South African Health Products Regulatory Authority
As stated in the MRSA and ZAF-9, the South African Health Products Regulatory Authority (SAHPRA) is the regulatory authority overseeing medicines and clinical research, as well as medical devices and radiation safety. As stated in the MRSA and GRMRSA, SAHPRA is responsible for clinical trial oversight, approval, and inspections in South Africa. The agency grants permission for clinical trials to be conducted in South Africa in accordance with the provisions of the GRMRSA.
Per the MRSA and ZAF-39, the SAHPRA is an independent, state-owned entity established to oversee the regulation of medicines in South Africa. According to ZAF-39, this agency is responsible for:
- The regulation of health products intended for human and animal use
- The licensing of manufacturers, wholesalers, and distributors of medicines and medical devices; radiation emitting devices; and radioactive nuclides
- The conduct of clinical trials in a manner that is compatible with national medicines policy
Per the MRSA, SAHPRA is a state-owned entity within the public administration but outside the public service. It acts through a Board appointed by South Africa’s Minister of the National Department of Health (NDOH). For details on the Board appointments, see ZAF-39 and ZAF-38.
As described in ZAF-39 and the SA-GCPs, SAHPRA is tasked with regulating (monitoring, evaluating, investigating, inspecting, and registering) all health products. This includes clinical trials, complementary medicines, medical devices, and in vitro diagnostics (IVDs). Its mission is to promote access to health products and protect human and animal health in South Africa through science-based regulatory decisions. Per ZAF-36, SAHPRA’s Clinical Trial Committee (CTC), within the Clinical Trial Unit, reviews clinical trial applications and bioequivalence studies for human participants and recommends approval of the conduct of clinical trials. SAHPRA also authorizes the importation of unregistered medicine for the purpose of conducting clinical trials. The SA-GCPs also states that SAHPRA is responsible for the following: ensuring efficient, effective, and ethical evaluation or assessment of health products that meet defined standards of quality, safety, efficacy, and performance; ensuring that the process of evaluating or assessing and registering health products is transparent, fair, objective, and concluded in a timely fashion; ensuring periodic re-evaluation and monitoring of health products; and conducting announced and unannounced inspections.

Overview
In accordance with the GRMRSA, the South African Health Products Regulatory Authority (SAHPRA) is responsible for reviewing and approving all clinical trial applications for an unregistered medicine, and for any new indication or dosage regimen of a registered medicine. The scope of the SAHPRA’s assessment includes all clinical trials (Phases I-IV) and bioequivalence/bioavailability studies. Per ZAF-23, the review and approval of clinical trial applications by SAHPRA and a registered ethics committee (EC) may be conducted in parallel. However, the G-EthicsHR-ZAF recommends that scientific review be completed prior to ethics review, and in cases where scientific review capacity is not available, the EC approval should be delayed until SAHPRA scientific approval has been provided.
ZAF-36 states that the SAHPRA’s Clinical Trial Unit (CTU) provides the legal framework for the review of clinical trials and bioequivalence studies for human participants and recommends approval of the conduct of clinical trials. The unit also authorizes the importation of unregistered medicines for the purpose of conducting clinical trials. As per G-GenInfo, the CTU is responsible for the evaluation of clinical trial applications, clinical trial amendments, and adverse event reports arising from a clinical trial.
Clinical Trial Review Process
Per ZAF-36, the CTU of SAHPRA receives, processes, and evaluates clinical trial applications and any subsequent amendments for approval to conduct a study within South Africa. Researchers must submit a completed application and the prescribed fee on predetermined dates (ZAF-11). The proof of delivery, proof of payments, and cover page must be sent to SAHPRA via email.
As stated in ZAF-36, the CTU completes a preliminary screening of the application and sends an official letter to the applicant with the outcome and follow-up questions on a screening checklist. As indicated in ZAF-23, incomplete documentation or sub-standard submissions will be rejected. Additionally, applications submitted without clinical trial insurance will be rejected. Applicants will be allowed a maximum of two (2) rounds of queries to respond to, and if the responses are not satisfactory, the application will be rejected. Per ZAF-36, if an application is rejected, no response is required; the screening checklist should be used as guidance for resubmission during the next review cycle. Next, the CTU’s Clinical Trial Committee (CTC) (which includes an expert committee of specialists, as needed) reviews the proposed clinical trials pursuant to the schedule on SAHPRA’s website. (See ZAF-11 for 2025 dates). Per ZAF-1, clinical trial reviews will result in one (1) of the following outcomes:
- Category 1A: Approved; no items pending
- Category 1B: Approved; ethics approval pending
- Category 2A: Not approved; for approval by in-house evaluators, 1-2 or more items outstanding as deemed by the committee
- Category 2B: Not approved; for approval by the original evaluator and in-house if a need arises
- Category 3: Not approved; items outstanding to be discussed at the next CTC meeting
- Category 4: Not approved; for referral for specialist opinion
- Category 5: Not approved – technical/scientific deficiencies; applicant to resubmit for the next cycle
- Category 6: Rejected due to administrative and technical items outstanding; applicant to resubmit for the next cycle
If an applicant would like to request a meeting with the CTC, the request should be submitted through the SAHPRA Chief Executive Office pursuant to the procedures in the G-ConsultMtg.
Other Considerations
Per the G-Capacity, SAHPRA will also review clinical trial applications for evidence of plans to build capacity at each study site as well as enhancing research activities and skills of professionals from historically disadvantaged groups. See G-Capacity for detailed information on actions that will comply with this requirement.
In addition, see G-Clin for South Africa's use of a “reliance model” to register medicines based on clinical trial data from other regulatory authorities.
Overview
As indicated in the TMMDAct and the CT-Regs, the Tanzania Medicines and Medical Devices Authority (TMDA) is responsible for reviewing, evaluating, and approving clinical trial applications in Tanzania. The scope of the TMDA’s assessment includes all clinical trials (Phases I-IV). As delineated in the TMMDAct, the CT-Regs, and the G-AppConductCT, the TMDA’s approval of a clinical trial application is dependent upon obtaining proof of national ethics committee (EC) approval from the National Health Research Ethics Committee (NatHREC). According to the G-AppConductCT and TZA-4, the TMDA and national EC reviews may be conducted in parallel. However, the TMDA application must include a copy of the national EC's acknowledgement of receipt for the study protocol. In addition, the TMDA's approval will only be finalized once national EC approval is obtained.
As described in TZA-2, TMDA’s Clinical Trials Control and Pharmacovigilance (CTPV) section is responsible for the regulation of clinical trials, pharmacovigilance, and post-marketing surveillance. Its functions include the following:
- Review and assess applications to conduct clinical trials in Tanzania, including evaluating clinical trial protocols, including preclinical studies, clinical data, and quality of investigational products (IPs)
- Approve clinical trial applications with minimum requirements
- Inspect clinical trial sites to ensure compliance with good clinical practices (GCPs), good clinical laboratory practices (GCLPs), clinical trials regulations, guidelines, standard operating procedures (SOPs), and internationally accepted standards
- Update and maintain the Tanzania Clinical Trials Registry, which is accessed via the Regulatory Information Management System (RIMS) Customer Self Service Portal (TZA-34)
- Review and evaluate all safety information (adverse events) from clinical trials
- Review and evaluate progress reports of all approved clinical trials
- Serve as Secretariat to Tanzania’s Clinical Trials Technical Committee
- Monitor and respond to all inquiries regarding conduct of clinical trials in Tanzania
Per the G-ResearchClearance, the Tanzania Commission for Science and Technology (COSTECH) must review and approve all research in Tanzania to:
- Ensure research conduct complies with national laws and regulations
- Document and register research
- Secure research results and promote its use in policy and practice
- Safeguard the dignity, rights, safety, and well-being of research participants
- Reduce systemic risks imposed through the research
- Provide research permits
Clinical Trial Review Process
Tanzania Medicines and Medical Devices Authority
As set forth in the TMMDAct, the CT-Regs, and G-AppConductCT, the TMDA coordinates the clinical trial application process. Upon receipt of a clinical trial application, the TMDA initially screens the application for completeness. If complete, the TMDA officer acknowledges receipt of the application by returning a signed copy of the cover sheet to the applicant (see Annex 1 of the G-AppConductCT). The TMMDAct states that the TMDA Director General must issue a Clinical Trial Certificate to authorize the trial to be conducted. (See the Submission Content section for submission requirements.) TZA-4 indicates that the TMDA may request a clarification or additional documents through the online submission system (TZA-34). The assessment will resume once the applicant has provided clarification and responded to the queries.
Per the G-AppConductCT, the TMDA reviews clinical trial applications and amendments to assess the quality of the products and determine that the use of the IP for the purposes of the clinical trial does not endanger the health of participants or other persons, the clinical trial is not contrary to the best interests of a participant, and the objectives of the clinical trial may be achieved. Evaluation of applications is conducted on a first-in, first-out basis unless the IP meets the fast-track criteria. The application assessment must involve the TMDA and external evaluators. If the TMDA requests additional information from the applicant, the evaluation process will stop until the TMDA receives a written response to the query. The response should be submitted within six (6) months after being issued with a query letter. All queries issued in the same letter must be submitted together in one (1) transaction. Non-compliance to these requirements in content and format will lead to rejection of the clinical trial. Evaluation of applications will be completed within 60 working days of receiving the application. A new clinical trial application may be fast tracked and assessed within 30 working days of its submission if the applicant has requested this and paid twice the prescribed clinical trials application fees. If authorization is not granted, an appeal may be submitted to the TMDA within 60 days of the TMDA’s decision. If no appeal is submitted by the applicant within this period or, if after consideration of any comments submitted, the TMDA is still not satisfied, it must reject the application. In an appeal, the applicant must give grounds for review for each reason given for the rejection of a clinical trial. The grounds for the appeal request must be based on the information that was submitted in the application. Any additional or new information that was not earlier submitted will only be considered upon submission of a new application. The TMDA may review, reject, or vary its own decision.
Per the G-AppConductCT, the clinical trials certification will be valid up to the proposed duration of the study indicated in the application. However, the validity will not extend beyond five (5) years. If the trial will last more than five (5) years, the applicant must request an extension. Further, the TMDA must approve amendments to a previously authorized protocol for changes that affect participant selection and monitoring; changes that affect clinical efficacy and safety requirements; changes that affect participant discontinuation; addition/deletion of an investigational site(s); changes that result in the extension of trial duration; and/or changes that relate to the chemistry and manufacturing information that may affect drug safety and quality. An application for amendment(s) must be accompanied by clearance or authorization from NatHREC.
The G-AppConductCT indicates that the TMDA must not authorize a clinical trial where it finds that:
- The information and documents as set out in the guidelines have not been provided
- The application contains false or misleading information
- The information provided is insufficient to enable the TMDA to assess the safety and risks of the IP or clinical trial
- Queries raised by the TMDA in relation to the application were not adequately responded to
- The applicant has not submitted an ethical clearance from any approved medical research institute
- The use of the IP for the purposes of the clinical trial endangers the health of a clinical trial participant or any other person
- The objectives of the clinical trial will not be achieved
- It is not in the public interest to authorize the clinical trial
- Any other reasonable grounds as may be determined by the TMDA
Next, the G-AppConductCT states that following the TMDA’s authorization of a new clinical trial or amendment, information regarding refusals by other regulatory authorities or ECs should be submitted as a notification. Further, the TMDA may suspend, terminate, or withdraw authorization of a clinical trial if it finds that the conditions of authorization of a trial have been violated; or there is information raising doubts about the safety or scientific validity of the trial or the conduct of the trial at a particular trial site. For additional information, see TZA-4.
(See the Submission Process section for additional details on the clinical trial application and amendments submissions.)
Tanzania Commission for Science and Technology
As for COSTECH review, the G-ResearchClearance indicates that once COSTECH receives a new application, the Secretariat screens the application for completeness; registers the application; sends an acknowledgement to the applicant; submits the application for the appropriate expert, local, and National Research Clearance Committee (NRCC) review; records NRCC’s final decision; and informs the applicant of the decision. COSTECH’s NRCC must reach a decision through a consensus of members forming a quorum at their meeting. The decision may be approval without amendments, approval subject to minor or major amendments, a denial, or a postponement pending further information. If approved, researchers should collect their permit within 90 days after the decision is communicated, and failure to do so requires a new application.
Per the G-ResearchClearance, permits are valid for one (1) year, and can be renewed, provided that COSTECH receives satisfactory progress reports for the previous periods. COSTECH must review the research to ensure compliance with the approved permit and see if any material changes have occurred in the research or if there are findings that may cause termination. The principal investigator (PI) must write to COSTECH two (2) months before the expiration date to request a renewal of the permit. For renewals, COSTECH will submit the registered application to an internal reviewer for evaluation, and otherwise, follow the same review and notification procedures as outlined above for a new permit. Regarding applications for amendments, if there is a change in PI, the affiliate institution must notify COSTECH within one (1) month of the departure of the outgoing PI in writing with an accompanying progress report. If a new researcher joins an ongoing project, the PI must submit a request for a research permit for the new member to COSTECH at least two (2) months prior to joining the team, accompanied with a detailed CV and rationale. Changes to the study site, objectives, and methodologies for an ongoing research project must be submitted in writing to COSTECH at least two (2) months prior to implementing the change.
See TZA-47 for additional information about national research registration.

Overview
As stipulated in the NHA, ethics committees (ECs) in South Africa are governed by the National Health Research Ethics Council (NHREC), which is a statutory body established under the NHA. NHREC determines guidelines for the functioning of ECs and registers and audits ECs, among other functions. Further, according to the NHA and ZAF-52, NHREC gives direction on ethical issues relating to health and develops guidelines for the conduct of research involving humans and animals. As delineated in the NHA, the G-EthicsHR-ZAF, and the SA-GCPs, all ECs are required to register with the NHREC in order to undertake the ethical review of a clinical study.
The NHA and the G-EthicsHR-ZAF require that every institution, health agency, and health establishment at which research is conducted establish an EC or have access to an independent EC that is registered with the NHREC. Per the G-EthicsHR-ZAF, researchers without affiliation to an institution or organization with an EC should approach a registered EC to request it to review their health research protocols.
Ethics Committee Composition
As delineated in the SA-GCPs and the G-EthicsHR-ZAF, an EC must consist of members who collectively encompass the qualifications and experience required to review and evaluate the scientific, medical, and ethical aspects of all proposed research studies. Further, per the G-EthicsHR-ZAF, ECs should be independent, multidisciplinary, multi-sectoral, and pluralistic. In general terms, membership should include the following:
- As many disciplines, sectors, and professions as possible, appropriate to the remit of the specific EC
- Members from diverse age groups and academic or professional ranks
- Ethnically and culturally diverse members and an appropriate mix of genders
- Lay persons
- Researchers who do not conduct human participant research or animal use research
The G-EthicsHR-ZAF states that subject to institutional requirements, a chairperson could be appointed or elected at the first meeting of a newly constituted EC. Alternatively, the chairperson could be appointed by the institutional leadership for a period of three (3) to five (5) years, renewable once, if so specified in the terms of reference. The chairperson must have experience in research methodology and research ethics, should have at least two (2) years’ experience as an EC member and should have leadership experience. If the chairperson is an external appointee, the institution must provide the chairperson with the necessary support and authority to perform the role. The chairperson should be assisted by at least one (1) deputy chairperson, who is elected by the EC members and assists the chairperson and serves as the role of chairperson when necessary.
As delineated in the G-EthicsHR-ZAF, the composition of ECs should promote optimal human participant welfare, research integrity (including data robustness and scientific validity), defendable significance of proposed research questions (including translatability of scientific findings into practice, where applicable), as well as legal, professional, and regulatory compliance. All EC members should have documented proof (i.e., evidence) of research ethics training, refreshed at least once. EC membership should consist of:
- A minimum of nine (9) members with a quorum being a simple majority; where the number of members is more than 15, the quorum may be 33%
- At least one (1) layperson
- At least one (1) member with knowledge of, and current experience in, the professional care, counselling, or health-related treatment of people, (e.g., a social worker, nurse, psychologist, or medical practitioner)
- At least one (1) member with professional training and experience in qualitative research methodologies
- Members with professional training and experience in quantitative research methodologies
- A member with expertise in biostatistics
- A member with expertise in research ethics
- At least one (1) member who is legally qualified and has extensive knowledge of family law, health law, and research ethics
Terms of Reference, Review Procedures, and Meeting Schedule
Per the G-EthicsHR-ZAF, when appointing EC members, institutions should be mindful of the need for ECs to develop institutional memory among the membership as well as to ensure succession planning. Members of ECs should be appointed formally for periods of three (3) to five (5) years, renewable once, after which the member should step down for at least one (1) term. Appointments should overlap so that no more than half the committee membership is new at any one appointment time. ECs should have standard operating procedures (SOP) that specify meeting attendance expectations, possible sanctions if attendance is poor, expectations for promptness of reviews, preparation for meetings, agenda, minutes, etc. ECs must define the review timelines in their SOPs. The appointment letter should describe the essential expectations of membership. ECs should provide induction training for new members that includes discussion of the role of EC members, the code of conduct, expectations of integrity, and confidentiality. Each EC should also have terms of reference that include the delegated and inherent authority as well as the scope of the EC's authority, its responsibilities, its relationship to non-affiliated researchers, its accountability responsibilities, and the mechanisms for reporting and remuneration, if any, for members. See the G-EthicsHR-ZAF for a sample terms of reference.
In addition, per the G-EthicsHR-ZAF, EC members are expected to familiarize themselves with the institutional documentation, as well as the national and relevant international research ethics guidelines, and should have documented proof of such familiarity, e.g., an assessment of training certificate, not a mere attendance certificate. See the G-EthicsHR-ZAF for additional training requirements. The SA-GCPs stipulate that EC members who review clinical trial proposals should have research ethics training and good clinical practice training, evidenced by certificates issued in the last three (3) years.
The G-EthicsHR-ZAF states that it is important for ECs to have clear SOPs that clarify the expectations about EC members’ review responsibilities. For EC meetings, the quorum should be a simple majority, and where the number of members is more than 15, the quorum may be 33%.
Per the G-EthicsHR-ZAF, institutions must have a Code of Conduct for EC members, which details the conduct and integrity expectations of members, including regular and punctual attendance at meetings, diligent performance of responsibilities, maintenance of confidentiality, and management of potential conflicts of interest. The induction process for new members should require that they sign the Code of Conduct to indicate they know and understand the expectations. (See A2.6 Code of Conduct for REC members sample.) Institutions must also ensure there is a formal appointment letter for EC members that sets out the term of office and the assurance that members are indemnified from personal liability against claims that may arise in the course of ordinary business of the EC.
Per the G-EthicsHR-ZAF, ECs should correspond primarily with the principal investigator (PI) or a delegated signatory, and not with the sponsor unless dictated by specific circumstances. EC members should disclose information that may lead to potential, actual, and perceptions of conflict of interest. EC members should not review or make decisions about research protocols in which they are involved personally (including as supervisor of a student) or financially. When such a protocol is to be discussed, the member concerned must declare the potential conflict and offer to recuse themselves from the meeting for that time. Should the member be permitted to remain for the discussion at the discretion of the chairperson (e.g., to facilitate clarifications), the member must leave the meeting for the duration of the final decision-making discussion concerning the application in question. EC members and ad hoc reviewers must not use the ethics review process to impose personal biases, professional jealousy, or territorial protection conduct about an applicant's protocol, including about research methods or the topic. If applicants pay fees for the ethics review service, this must not negatively affect the rigor of reviews, the integrity of the process, or the capacity to monitor the research that the EC approves. The EC should be alert to whether an advocate for special interest groups of participants proposed for specific research would add value to the review process for informed responsible decision-making in the context. The EC should be alert to the potential for poor consent processes in the absence of appropriately translated materials and the availability of interpreters.
Regarding archiving and record keeping, the G-EthicsHR-ZAF states that ECs should keep written records of all research protocols received for review, including information sheets, consent forms, and relevant correspondence, in the form in which they were approved. Electronic records are acceptable, provided the signatures, especially on the finally approved documentation, are properly documented and included in the record. EC records must provide a reliable and authoritative record of the business of the EC that will stand up to scrutiny in the event of queries, conflict, and audit. The record should include at least the following:
- Name of PI
- Protocol identification number
- Title of the project
- Date of approval or rejection
- Duration of approval period (maximum 12 months, renewable)
- Conditions of approval, if applicable
- Whether approval was expedited
- Copy of the signed final protocol or protocol approved
- Whether and how consultation occurred
- Records of adverse events
- Records of amendments
- Reports of adverse and serious adverse events and action taken
- Other relevant information such as complaints from participants
Per the SA-GCPs, the EC should retain all relevant records for a period of at least three (3) years or as per institutional requirement, whichever period is longer, after completion of the trial and make them available upon request from the applicable regulatory authority.
Overview
As indicated in the G-AppConductCT, all clinical trials require national ethics committee (EC) approval for each trial site. Per the G-TMRCC and TZA-50, the national EC in Tanzania is the National Health Research Ethics Committee (NatHREC), which focuses on the ethical issues surrounding submitted research proposals. As delineated in the G-TMRCC, NatHREC-Charter, TZA-5, and TZA-18, NatHREC is a subcommittee of the Medical Research Coordination Committee (MRCC), which serves as the national health research coordinating body, and is responsible for supervising, controlling, coordinating, evaluating, and promoting health research in Tanzania or elsewhere on behalf of or for the benefit of Tanzania. The MRCC, which is part of the National Institute for Medical Research (NIMR), delegates the registration, review, approval, and monitoring of clinical research to the NatHREC.
As delineated in NatHREC-Charter, NatHREC provides ethical review and clearance of health research protocols and monitors and evaluates research studies. In addition, NatHREC conducts the following activities:
- Receiving and registering all health research carried out in Tanzania
- Ensuring that all health research protocols are thoroughly reviewed to safeguard the dignity, rights, safety, and well-being of research participants
- Advising researchers on the risks and responsibilities of conducting research
- Recommending to the MRCC for ethics clearance approval, all health research protocols that have complied with the country’s ethics regulations and guidelines
- Monitoring and coordinating all approved health research conducted in Tanzania
- Advocating for and overseeing all issues pertaining to health research data and material sharing and/or transfer
- Supporting health research institutions in Tanzania to establish institutional ECs or Institutional Review Boards (IRBs)
- Accrediting health research institutions’ ECs
Per the G-AppConductCT, G-EthicsHR-TZA, the G-ResearchIntegrity, the G-RevPrtcl, TZA-18, TZA-5, and TZA-1, all health research involving foreign collaborators must get ethics approval from both the institutional EC and NatHREC. In addition, TZA-5 specifies that the following also require review by both NatHREC and the zonal or institutional EC: all clinical trials; research dealing with vulnerable, special, or marginalized groups; and sensitive topics or indigenous communities. Protocols that do not involve foreign collaborators and non-clinical trials of investigational products (IP) can be reviewed and given ethics clearance at the zonal or institutional level. NatHREC may request zonal or institutional EC reviewers to assist in review or joint review of protocols when needed. The NatHREC-Charter indicates that institutional and zonal ECs complement NatHREC’s function of issuing institutional ethics clearance certificates and monitoring the approved research at their institutions. TZA-18 states that if there is no institutional EC available, the approval must be obtained from NatHREC.
The G-EthicsHR-TZA further states that institutional ECs should monitor their hosted research activities to ensure compliance. Institutional ECs may function at the institutional, zonal, or national levels. ECs act as independent reviewers of any proposed study on human research participants, to ensure ethical conduct of research, and that participant’s rights and welfare are not violated. The major responsibility of ECs is to safeguard the rights, safety, and well-being of research participants. See the Oversight of Ethics Committees section for information on the registration and accreditation of ECs by NatHREC.
Ethics Committee Composition
National Health Research Ethics Committee
Per the G-EthicsHR-TZA and TZA-5, the Director General of NIMR is responsible for appointing NatHREC members. Members are selected based on their capacity, interest, ethical and scientific knowledge, and expertise, as well as their commitment and willingness to volunteer the necessary time and effort for the NatHREC’s work. NatHREC must consist of not less than nine (9) and up to 15 members with the relevant qualifications and experience to review and evaluate the science, medical, and ethical aspects of health research protocols. In addition, NatHREC must be composed of members with varying backgrounds to promote a complete and adequate review of health research protocols commonly received by the NatHREC. Per TZA-5, committee members must include medical scientists, biomedical scientists, social scientists, legal representatives, unaffiliated community representatives, representatives of religious or faith-based organizations, a representative from the President’s Office-Regional Administration and Local Government (PO-RALG), and a representative from the Tanzania Ministry of Health. The Director General may appoint additional members depending on the need for expertise and/or representation and not exceeding the maximum number of members. Regarding leadership, the NatHREC Chairperson must be elected from among appointed members but must not be an employee of NIMR. The NatHREC Secretary, however, must always be an employee of NIMR. See TZA-5 for additional information on NatHREC’s standard operating procedures (SOPs).
Per the G-TMRCC, the NatHREC is represented by the following organizations:
- NIMR
- Tanzania Commission for Science and Technology (COSTECH)
- Muhimbili University of Health and Allied Sciences (MUHAS)) (formerly known as Muhimbili University College of Health Science (MUCHS))
- Christian Social Services Commission (CSSC)
- The National Muslim Council of Tanzania (BAKWATA)
- Economic and Social Research Foundation (ESRF)
- Tanzania Gender Networking Programme (TGNP)
- Legal and Human Rights Centre (LHRC)
- University of Dar es Salaam (UDSM)
- Ministry of Health (MoH)
- Ministry of Education (MoE)
Institutional Ethics Committees
As per the G-EthicsHR-TZA, institutional ECs must have members capable of providing a competent and thorough review of research protocols. Membership typically includes physicians, scientists, laboratory experts, nurses, lawyers, ethicists, and other professionals. In addition, the above membership also includes community members or representatives of patients’ groups who can represent the cultural and moral values of study participants. When a proposed study involves vulnerable individuals or groups, as may be the case in research involving prisoners or illiterate persons, representatives of relevant advocacy groups should be invited to meetings where such protocols will be reviewed. Regular rotation of members is desirable for balancing the advantage of experience with that of fresh perspectives. In addition, each institutional EC must include at least one (1) member who is not affiliated with the institution and is not part of the immediate family of a person who is affiliated with the institution. Further, an EC may invite individuals with competence in particular areas to assist in the review of issues, which require expertise beyond, or in addition to that available in the EC; these individuals do not vote with the EC.
Per IERC-Accredit, following are the membership requirements for ECs accredited with NIMR:
- The Chairperson must have adequate experience in health research, leadership, and have basic knowledge of bioethics
- An EC must comprise at least five (5) members or more, and the total must be an odd number
- At least one-third of the members of the EC must be of either gender
- At least one (1) member should come from outside the institution
- At least two (2) members should have research expertise and experience, and one (1) of these should be in the health field
- At least one (1) member should represent a lay group
- For ECs reviewing clinical research, the committee should have representation from medicine, laboratory, pharmacy, and nursing as needed; a clinician who is active in clinical practice (with a valid practicing license) or in clinical research is mandatory
- At least one (1) member of the EC should possess knowledge and understanding of Tanzanian law
- Where an EC has been formed to serve more than one (1) institution, the institution hosting the Secretariat is responsible for the functioning of the EC in all aspects
- Where multiple institutions are involved in one (1) EC, the appointing authority must make appointments in consultation with the relevant heads of the respective institutions
The G-ResearchIntegrity recommends that composition should not only be multi-disciplinary and multi-sector but should also balance scientific expertise, age, and gender distribution, and should have a non-technical member representing community interests. The institution should determine the type of members needed and establish procedures for selecting/appointing members and number of persons. It is recommended that ECs have seven (7) to 15 members. See the G-ResearchIntegrity and TZA-23 for additional recommendations.
Terms of Reference, Review Procedures, and Meeting Schedule
National Health Research Ethics Committee
The G-TMRCC and TZA-5 state that the NatHREC must operate within written SOPs, including a process to be followed for conducting reviews. The G-TMRCC states that the SOPs should include information on NatHREC composition, meeting schedules, frequency of reviews, requirements for initial and ongoing evaluation of the research study, and requirements for notifying the investigator and the institution of results related to the study’s initial and ongoing evaluation. Committee members should agree to disclose their names, occupations, and affiliations, and to sign the confidentiality and conflict of interest agreements. Per TZA-5, the SOPs facilitate and support ethical review by improving the standard and uniformity of decision-making and assuring and gaining the confidence of the public in the NatHREC. Membership must be for three (3) years, renewable once, under the discretion of the MRCC Chairperson. A member of the NatHREC may resign by submitting an official letter of resignation to the MRCC Chairperson. A member of the NatHREC may also be disqualified from membership should the appointing authority provide adequate written reasons to the NatHREC and there is unanimous agreement. The NatHREC must request a replacement of any member when there is protracted illness that prevents the member from participating; persistent absenteeism or missing three (3) consecutive committee meetings; voluntary withdrawal or resignation; and/or ethical misconduct.
According to TZA-5, the NatHREC Secretary oversees the daily operations of the Secretariat and arranges training and educational programs to new and continuing committee members and the scientific community on health research ethics. The training must include programs about the basic principles of human participant protection, current literature, and regulations and guidelines affecting the committee and NIMR. Further, the Secretary assists in recruiting new committee members, as well as preparing and submitting an annual committee operational budget and plan to NIMR in consultation with the Chair. See TZA-5 for details on the functions of the NatHREC Secretariat.
Per TZA-5, NatHREC members must fulfill the following responsibilities:
- Review, discuss, and consider health research protocols submitted for ethical clearance evaluation
- Review research study progress reports and monitor on-going studies as appropriate
- Review reports on adverse events, serious adverse events, and/or suspected unexpected serious adverse reactions, as well as any other safety reports and recommend appropriate actions
- Maintain professional confidentiality of documents and deliberations of the committee review proceedings and meetings
- Declare conflicts of interest when they exist
- Participate in continuing education activities in biomedical ethics and research
- Undertake committee duties assigned to them by the NatHREC Chairperson
- Attend NatHREC meetings regularly and participate actively during deliberations
- Participate in the review of NatHREC SOPs
- Conduct research site monitoring visits as deemed necessary
According to TZA-5, the NatHREC must convene at least once a month with a quorum of at least half the number of committee members. The NatHREC Secretary, with support from the Secretariat, must prepare an annual almanac of meetings. The meeting package must include the agenda; all research protocols; and all related materials including, but not limited to, copies of the protocols, informed consent materials, continuing and final reviews, and safety reports. The Secretariat must keep a record of attendance as well as meeting deliberations, indicating which members were present and the discussions of review applications. If members have reviewed a protocol and identified issues that require the principal investigator (PI) to be present during the meeting for further deliberations, then the PI of that research protocol may be invited to answer questions or clarify issues. The meeting members must reach decisions by a consensus; however, if a consensus cannot be achieved, a formal vote must be taken. All members have the right to vote. The committee must provide formal recommendations to the MRCC on the approval of applications, along with minutes that include protocol title and date of review, a checklist of documents reviewed, and a decision reached by the committee, whether approved, approved with stipulation, recommended for resubmission after revision, or not recommended with reasons. For detailed NatHREC procedures and information, see TZA-5.
Institutional Ethics Committees
Per the G-EthicsHR-TZA, the EC members are appointed by institutional appointing authorities. The EC must be constituted according to a document that specifies the manner in which members and the Chair will be appointed, reappointed, and replaced. EC members must regularly update their knowledge about the ethical conduct of health-related research. If committees do not have the relevant expertise to adequately review a specific protocol, they must consult external persons with the required skills or certification. Each EC member must undergo at least one (1) basic training in research ethics within one (1) year of appointment and, thereafter, should undergo continued ethics training at least once every two (2) years. Members of an EC must serve for a term of three (3) years. EC members must guard against any tendencies of unethical conduct on their part. For example, they must protect the confidentiality of research projects, documents, and discussions; an EC member must not appropriate the submitted protocol for their own use; and they must not compel investigators to submit to an unnecessary repetition of review.
In addition, as delineated in the G-EthicsHR-TZA, ECs are responsible for determining whether the research objectives are responsive to the health needs and priorities of the proposed study population, particularly in Tanzania. The ability to judge the ethical acceptability of various aspects of a research protocol requires a thorough understanding of a community’s customs and traditions. For example, the EC should include members that are able to indicate suitable community members to serve as intermediaries between investigators and research participants and to advise on whether material benefits or inducements may be regarded as appropriate considering a community’s gift exchange and other customs and traditions. ECs must have mechanisms to ensure the independence of their operations. They must avoid undue influence and minimize and manage conflicts of interest. ECs must require that their members disclose to the committee any interests that could constitute a conflict of interest or otherwise bias their evaluation of a research protocol. ECs must evaluate each study considering any disclosed interests and ensure appropriate steps are taken to mitigate possible conflicts of interest. ECs may receive a fee for reviewing protocols, and this need not constitute a conflict of interest.
As required in the G-EthicsHR-TZA, ECs should hold meetings as frequently as possible to facilitate timely ethical clearance. ECs must review proposed research at convened meetings where at least 50 percent of the members are present, including at least one (1) member who represents the interests of the community. The Chairperson may be given powers to approve minor matters on behalf of the EC but ensure that the papers are made available to the rest of the EC members at the next meeting. ECs should have the power to co-opt professional or lay members where necessary. For a research protocol to be approved, it must receive the approval of a simple majority of those members present at the meeting; the only exception to the simple majority requirement is in the case of expedited review.
Regarding documentation, per the G-EthicsHR-TZA, the institution must ensure that the EC prepares and maintains adequate documentation and retain the records for at least five (5) years after the completion of the study. All records must be accessible for inspection and copying by authorized representatives, including the following:
- Detailed written procedures for the EC
- Copies of all research protocols reviewed, scientific evaluations that accompany the protocols, approved sample consent documents, progress reports submitted by the investigator(s), reports of injuries to research participants, etc.
- Minutes of EC meetings that must be in sufficient detail to show attendance at the meetings; actions taken by the IRB; the vote on these actions, including the number of members voting for, against, and abstaining; the basis for requiring changes in or disapproving research; and a written summary of the discussion of controversial issues and their resolution
- Records of continuing review activities
- Copies of all correspondence between the EC and investigator(s)
- Statements of significant new findings that were provided to research participants
Per the G-ResearchIntegrity, institutions should have clear documentation of candidacy requirements and procedures for identifying or recruiting EC members. The recruitment methods, duration of membership, terms of service, qualifications, disqualifications, resignation procedures, re-appointment/renewal, and other duties and responsibilities should be documented in EC SOPs. Appointment of EC members must be done at the institutional managerial level in consultation with experts, relevant boards, and peer institutions. Institutions should minimize conflicts of interest and establish mechanisms for maximizing transparency and confidentiality of review processes. These qualities may be enhanced by rotation and turnaround of members to allow inflow of new ideas and accountability. The conditions of appointment must clearly indicate the decision on whether to release professional profiles to the public, level of accessibility, members’ cost recovery ceilings for EC-related activities, confidentiality, and any other mechanisms geared to enhancing confidence over the EC’s operations. The pros and cons of each option must be carefully considered and communicated to candidates. Both scientific and support staff must sign a confidentiality agreement and declare any conflicts of interest from the outset.
Overview
Per the SA-GCPs, clinical trials should be conducted in accordance with all ethical principles outlined in the Declaration of Helsinki (ZAF-44) and consistent with good clinical practice and other applicable regulatory requirements. In accordance with the NHA, the SA-GCPs, and the G-EthicsHR-ZAF, ethics committees (ECs) must evaluate the ethical and scientific rigor of all research studies to be conducted in the country. An EC’s primary responsibilities are to (Note: Each of the items listed below will not necessarily be found in all sources, which provide overlapping and unique elements):
- Review protocols to ensure that research involving human participants has scientific merit and will promote health, and prevent or cure disability and disease; in addition, ensure the research has social merit in light of South Africa’s research priorities or is otherwise justified
- Ensure clinical trials are governed by the ethical principles of beneficence and non-maleficence, distributive justice (equity), and respect for persons (dignity and autonomy)
- Uphold the key norms for ethical research with human participants including relevance and value; scientific integrity; stakeholder engagement; fair selection of participants; informed consent; ongoing respect for enrolled participants; and researcher competence and expertise
- Grant approval for research where the protocols meet the ethical standards of the institution, agency, or establishment
- Determine whether and why randomization is relevant, and how this is addressed
- Evaluate the appropriateness of the inclusion/exclusion criteria and the recruitment process in the South African context
- Ensure the feasibility of obtaining meaningful results with the lowest possible risk of harm for participants and whether the risk of harm is appropriately weighed against anticipated benefits for participants or the class of persons from which they are drawn; high risk of harm may be justifiable where the anticipated benefit is of high importance to increase relevant knowledge and appropriate mitigating measures are in place to minimize harm to participants; and attention must be given to harms and benefits beyond the life of the trial itself, especially in respect to early phase studies and (pharmacovigilance) surveillance for chronic and life-threatening conditions
- Protect the welfare of certain classes of participants deemed to be vulnerable (See the Informed Consent topic for additional information about these populations).
Role in Clinical Trial Approval Process
Per the G-EthicsHR-ZAF, the SA-GCPs, and the NHAParticipants, the principal investigator (PI) or the sponsor must submit a clinical trial application to both the South African Health Products Regulatory Authority (SAHPRA) and a registered EC for review and approval before a study may commence. Per ZAF-23, the review and approval of clinical trial applications by SAHPRA and a registered EC may be conducted in parallel. However, the G-EthicsHR-ZAF recommends that scientific review be completed prior to ethics review and, in cases where scientific review capacity is not available, the EC approval should be delayed until SAHPRA scientific approval has been provided. Further, where site permissions are required, e.g., from Provincial Health Research Committees (PHRCs) or superintendents, to conduct research in health care facilities, ECs must delay granting full approval until these permissions are received. This is to prevent research from beginning before the facility knows it will happen.
The G-EthicsHR-ZAF indicates that after the deliberative review process, the EC should approve, require amendment to, or reject a research protocol. In considering a research protocol, the EC may seek assistance from experts who have no conflicts of interest. EC decisions should be recorded in writing and appropriately documented in the minutes. A decision to approve should include the conditions (e.g., the duration of the approval, the reporting requirements, etc.). Reasons for a decision to require an amendment or to reject a research protocol should be recorded and provide sufficient feedback to the applicant. Outright rejection should be avoided if a researcher can be advised to improve the protocol. Researchers should be encouraged to address the concerns and improve their protocols. In addition, feedback should include the expected return date to minimize delays to finalize the approval process. The maximum time for a return date should not exceed six (6) months. Should the applicant exceed the stipulated return date without communication to the EC, the application should be removed from the agenda, and a new application must be submitted. ECs should require researchers to report immediately if a project is terminated or suspended before the anticipated date of completion. ECs should require researchers to report immediately anything that might warrant reconsideration of ethical approval of the protocol, including but not limited to:
- Serious or unexpected adverse effects on participants
- Proposed changes in the protocol
- Unforeseen events that might affect continued ethical acceptability of the project
Per the G-EthicsHR-ZAF, to prevent unnecessary duplication of work, ECs may, at their own discretion, recognize the review and approval of a research protocol granted by another registered South African EC. Reciprocal recognition means that two (2) or more registered ECs decide to recognize each other’s review. This arrangement may involve formal agreements between the ECs explaining how the workload and responsibilities are shared and the basis on which recognition occurs. Alternatively, the committee may decide to use reciprocity recognition on a case-by-case basis. ECs that recognize reciprocal review agree on the nature of the documents to be filed at each office. The expectation is that ECs should communicate with each other, through their chairpersons, and agree on a way forward regarding review of a multi-site protocol when it is desirable to avoid duplication of effort. The possibility of reciprocal recognition of reviews should occur in a collaborative, harmonious manner, bearing in mind that each EC retains the responsibility of protecting the safety, rights, and interests of participants enrolled in the studies it has approved. For more details on reciprocal review, see the G-EthicsHR-ZAF.
The SA-GCPs requires the EC’s approval of the following before the clinical trial may begin: protocol and any amendments; case report form, if applicable; informed consent form(s); any other written information to be provided to the participants; advertisement for participant recruitment (if used); participant compensation; and any other documents given approval/favorable opinion.
The SA-GCPs mandate that the sponsor receive confirmation of EC review from the investigator(s) or institution(s). The sponsor must receive the following information prior to the trial’s commencement:
- The name and address of the relevant EC registered with National Health Research Ethics Council (NHREC), with its documented approval
- If EC approval is conditional on required modifications, a copy of the modification(s) made and the date the final approval was granted by the EC
- Documentation and dates of any EC re-approvals/re-evaluations
Per the G-EthicsHR-ZAF and ZAF-20, if there is an amendment to the protocol, the sponsor must notify the EC and get its approval. This approval should be sent to the SAHPRA using the Application for Protocol Amendment to an Approved Trial (ZAF-20).
As delineated in the G-EthicsHR-ZAF, ECs have the right to monitor the research it approves. The frequency and type of monitoring should reflect the degree and extent of risk of harm to participants. Monitoring types include passive and active measures. Active monitoring requires a site visit. Passive monitoring is generally paper, using reports and other information. A site visit is expected for investigation of adverse events, serious adverse events for high-risk research, as well as other occurrences that prompt concerns for ECs. The EC should ensure that appropriate feedback is given to the PI, with an opportunity to address any identified gaps within a negotiated timeline. ECs may recommend and adopt any additional appropriate mechanism for monitoring, including random inspection of research sites, welfare monitoring sheets, data and signed consent forms, and records of interviews. ECs should ensure information and consent materials indicate that such monitoring may take place. Further, ECs should request regular, at least annual, reports from PIs. See the G-EthicsHR-ZAF for more details including the report requirements.
The G-EthicsHR-ZAF states that where circumstances indicate that a project is non-compliant with the approved protocol and the interests of participants are at risk of harm, the EC may withdraw approval, after due process has been followed. A clear process should be followed that permits swift but proper investigation and decision-making to ensure protection of participants. The investigation should include interaction with the researchers and other interested parties to ensure a fair and transparent process. If the decision is to withdraw approval, the EC should inform the PI and other interested parties, including the institutional authorities, and recommend suspension (temporary stoppage) or termination (permanent stoppage) of the project. It should also recommend remedial action where appropriate. In the case of suspension, the PI must comply with the recommendations and any special conditions imposed by the EC.
Expedited Review
Per the G-EthicsHR-ZAF, expedited review applies, in principle, only to research that poses no more than minimal risk of harm. Generally, expedited review means that no fewer than two (2) EC members review the protocol and that deliberation in the full committee meeting is foregone, unless the reviewers believe there are issues that the EC should discuss. The nature of research that may be expedited should be described in the procedures. The outcomes of the expedited review process must be reported to the full committee, at least by being noted on the agenda, so that the record is complete.
Rapid Review
As delineated in the G-EthicsHR-ZAF, rapid review process permits rapid but thorough processing of ethics review applications in circumstances that require accelerated preparation for a research study or project, for example when there is a national or localized emergency. The EC should carefully assess the nature of the research to determine the appropriate review process, bearing in mind that not all research during a major incident is necessarily urgent. Careful ethical reflection is essential, notwithstanding any perceived urgency. All the usual ethical norms and standards must be considered. The EC should have a review standard operating procedure (SOP) that allows a combination of rapid but thorough review and reciprocal recognition of review (see above) by other registered ECs. The SOP might stipulate that a small group of reviewers (3-5 persons) with appropriate expertise reviews the protocol. The deliberations and outcome of the process must be documented in minutes and reported to the full EC at its next meeting.
Joint Review
The G-EthicsHR-ZAF allows joint reviews wherein two (2) or more ECs review a multi-site research protocol together. The sites may be within South Africa or may include sites elsewhere on the African continent. A joint review is not the same as a reciprocally recognized review (described above). A joint review entails members of the ECs concerned communicating virtually or face-to-face to discuss their respective reviews and queries and come to conclusions. The joint review process permits efficiency of reviews, facilitation of capacity building, development of trust, and avoids unnecessary repetition of administrative work. When deliberations are completed and a decision to approve has been reached, each EC uses its own approval SOPs and processes. Joint review does not exempt any of the ECs involved from their responsibilities, including monitoring and looking after the interests of participants at their sites. The PIs concerned are responsible for informing their institutional EC of the fact of multi-site research, as well as the names of the other ECs with jurisdiction over other research sites. This information enables the chairs of the ECs to arrange a joint meeting of the ECs involved to review, deliberate on, and approve the protocol concerned simultaneously. Joint reviews involving South African and other African ECs can be used in a similar manner to facilitate the ethics review and approval processes. A memorandum of understanding is recommended between the ECs involved that outlines the process, the expectations, and the responsibilities.
Foreign Research Collaboration
The G-EthicsHR-ZAF indicates that where international research (multi-country studies) is conducted exclusively online or the online platform is used to recruit study participants, and the PI neither lives or works in South Africa, an exemption from ethics review and approval is possible. This is on the proviso that the PI can demonstrate to a local registered EC that permission has been obtained from the website owners and that a notice of research intent is posted on the relevant website. In addition, the PI must comply with the privacy policies and terms of website use, and with personal data protection requirements in the POPIA. (See the Personal Data Protection section for more information).
Artificial Intelligence
Per G-EthicsHR-ZAF, ECs must consider the following ethical considerations when reviewing protocols that involve the use of artificial intelligence (AI):
- Transparency in the context of AI necessitates openness and clarity at every phase of the research
- Researchers should explain how interpretable these models are, how this interpretation is communicated to a user, and to what extent interpretation is possible
- Responsibility and accountability—Researchers should have a sufficient understanding of the AI model/technology and take responsibility for its use. Information on technical engineering perspectives should be made available for the ECs conducting the review. The ethical and responsible use and deployment of AI tools remain the responsibility of the PI to ensure the protection of research participants’ data
- Equity and fairness—AI tools must be designed and implemented equitably and without unfair discrimination against any individual or group. Special attention should be given to vulnerable and historically underrepresented populations. Researchers should actively involve diverse participant groups in the design and testing phases to ensure fairness and representation. Additionally, algorithms should be assessed regularly for bias, and any discovered discrepancies should be promptly addressed and rectified
- Benefit sharing, with particular attention to the needs and contributions of low-income communities, should be considered. Evidence of fostering equitable and collective sharing of the benefits and burdens of research must be presented to the EC
- Safety risks and well as vulnerabilities to attack (security risks) should be addressed, prevented, and eliminated throughout the lifecycle of an AI system
- Researchers must prioritize safety in the implementation of AI-enabled systems, with thorough assessments of the risk of harm and strategies for mitigation
See the G-EthicsHR-ZAF for detailed guidance on the above AI considerations.
Overview
According to the G-TMRCC and the G-EthicsHR-TZA, the primary scope of information assessed by the National Health Research Ethics Committee (NatHREC) and the institutional ethics committees (ECs) relates to maintaining and protecting the dignity and rights of research participants and ensuring their safety throughout their participation in health research studies. The NatHREC and the institutional ECs must also pay special attention to reviewing informed consent and to protecting the welfare of certain classes of participants deemed to be vulnerable. (See the Vulnerable Populations; Children/Minors; Pregnant Women, Fetuses & Neonates; Prisoners; and Mentally Impaired sections for additional information about these populations). The NatHREC is responsible for ensuring an independent, timely, and competent review of all ethical aspects of the clinical trial protocol. TZA-5 states that the NatHREC must function in accordance with national and international standards and guidelines on health research, and guided specifically by the ethical principles expressed in the Declaration of Helsinki (TZA-30), international ethical guidelines such as the International Council for Harmonisation's Guideline for Good Clinical Practice E6(R2) (TZA-13), and the G-EthicsHR-TZA.
As indicated in the G-ResearchIntegrity, institutional ECs review, approve, and recommend for approval, research proposals that have met scientific merit, ethical, and professional standards. The institutional ECs are expected to provide recommendations on proposals that would need approval from a nationally overseeing ethics body where available. Per the G-EthicsHR-TZA, institutional ECs act as independent reviewers of any proposed study on human research participants to ensure ethical conduct of research and that participant’s rights and welfare are not violated. The major responsibility of institutional ECs is to safeguard the rights, safety, and well-being of research participants. In addition, it is essential that they review the scientific soundness of the research protocols, which involves a proper scientific review to verify that a competent expert body has determined the research to be scientifically sound, or consult with qualified experts to ensure that the research design and methods are appropriate. If the EC does not have expertise to judge science or feasibility, they must draw on relevant expertise. See G-EthicsHR-TZA for more information on the scientific review.
Role in Clinical Trial Approval Process
National Health Research Ethics Committee
As per the TMMDAct, the CT-Regs, and the G-AppConductCT, the Tanzania Medicines and Medical Devices Authority (TMDA) and the NatHREC must approve a clinical trial application prior to the sponsor, the contract research organization (CRO), or the principal investigator (PI) initiating the clinical trial. According to the G-AppConductCT and TZA-4, the TMDA and NatHREC reviews may be conducted in parallel. However, the TMDA application must include a copy of the national EC's acknowledgement of receipt for the study protocol. In addition, the TMDA's approval will only be finalized once national EC approval is obtained.
As described in TZA-31, the NatHREC’s ethics review is managed through its Research Ethics Information Management System (REIMS) (TZA-32) (also referred to as the National Health Research Management Information System (NHRMIS)), an online web application for the submission of research protocols for NatHREC’s review, validation of protocols per NatHREC checklist (TZA-1), online review of proposals, and application status tracking. The G-RevPrtcl indicates that the NatHREC Secretariat will validate submissions for completeness upon receipt in REIMS. The G-RevPrtcl recommends the following review sequence after the materials are checked for completeness: write comments in an MS Word document; read the PI’s cover letter, the institution’s commitment letter, and other supporting letters; review the abstract/summary; review the application form, protocol, and appendices; and synthesize and submit comments online through REIMS (TZA-32). Per TZA-5, following successful validation of an application to the REIMS, the system generates a unique protocol number/identifier; this unique identifier must be used in reference to all communications to the PI or applicant regarding the application. Depending on the research area of the submitted protocols, at least two (2) primary reviewers must be assigned to review a new protocol by the NatHREC Secretariat. Comments from reviewers will reach the PI within two (2) days, depending on the type of study protocol. If the applicant fails to respond to the comments within 30 days, the NatHREC Secretariat must notify the PI of its intent to remove the protocol from the REIMS. Once the research protocol is removed from the REIMS, the PI must re-apply for ethical clearance and pay the application fee. For clinical trial applications, reviewers’ comments and the outcome of the NatHREC meeting must be forwarded to the PI within 30 days from the date of acceptance by the NatHREC. If the research protocol is cleared and the ethical clearance certificate is issued, the PI must receive it via mail at the institution’s postal address. Additionally, the PI may be able to download the soft copy of the ethical clearance certificate from the REIMS account. A PI may appeal a decision in writing to the Medical Research Coordination Committee (MRCC) Chairperson within 30 days of receipt of the decision, stating the precise issues upon which the appeal is based. The MRCC will respond to PIs in writing within 30 days or upon scrutiny of the appeal. The MRCC Chairperson may invite the PI to appear in person to the MRCC within 30 days of receiving the written appeal.
Expedited Review
TZA-5 delineates the categories of research that qualify for NatHREC expedited review:
- Research activities that present no more than minimal risk to human participants
- Minor changes (modification or amendment) to a previously approved research proposal
- Studies that involve interviews of a non-confidential nature and not likely to harm the status or interest of study participants
- Studies that involve collection of small amounts of biological specimens by non-invasive means (e.g., body fluids, excreta, hair or nail in non-disfiguring or threatening manner) for local analysis and no transfer of specimens outside of Tanzania
- Collection of data for research purposes through non-invasive procedures (not involving general anesthesia or sedation), routinely employed in clinical practices and using medical devices which have been already approved for use
- Research involving data, documents, or specimens that have been already collected or will be collected for on-going medical treatment or diagnosis
- Continuing review of certain research previously approved by the NatHREC
- Research that aligns with disease outbreaks or public health emergencies
TZA-5 states that expedited review must be conducted by two (2) or more experienced reviewers designated by the Secretariat. The expedited review must include a review of the complete study protocol with all required attachments. Results of the review process may be communicated to the PI even before being reported to the NatHREC. Expedited reviewers may exercise all the authorities of the committee except that the NatHREC reviewers may not disapprove of the research. Any research activity may be disapproved only after reviewing the protocol in accordance with the non-expedited procedure. Approval for expedited protocols is given by the MRCC through the Chairperson upon recommendation for approval from the reviewers. Once expedited approval has been granted, the protocol may be implemented as approved. Clinical trials with investigational products (IP) are not eligible for expedited review but may be considered for accelerated review. The final decision for a protocol to undergo an expedited review is determined by the NatHREC Chairperson, the NatHREC Secretariat, and/or the MRCC Chairperson, as needed. The Secretariat must notify the NatHREC of all expedited reviews at the next scheduled meeting through a listing in the meeting agenda.
Reviews During Public Health Events
Per TZA-5, rapid review of public health research and clinical trials may be implemented during public health events of national and/or international concern. During public health emergencies, the declaration will come from the public health authority of the country or an internationally recognized organization responsible for international public health. To expedite commencement of the research, many of the preliminary research processes (drafting of documents, translations, approvals) will be allowed to happen in parallel. Protocols should be sent to reviewers within 24 hours of submission by the Secretariat, and reviewers should complete their reviews within three (3) days. The consolidated review and suggested revisions (or approval) should be communicated to the PI(s) within five (5) days. The PI should respond to the review notification within 48 hours. See TZA-5 for additional details on the emergency review requirements.
Approval Duration
Regarding duration of the NatHREC approval, per TZA-5, the NatHREC Secretariat determines how often the committee must re-evaluate the research study, appropriate to the degree of risk, but not less than once per year. Studies whose approval has expired must be suspended until an extension through a renewal process is approved. The PI must submit an electronic continuing review report through REIMS with a frequency as indicated in the terms and conditions of the ethics clearance certificate. The NatHREC Secretary must place the continuing review report on the next meeting’s agenda for review. The NatHREC may provide directives or guidance to the study following review that will be communicated to the PI. In addition, the committee may recommend that the research study is halted.
Protocol Amendments
Per TZA-5, the NatHREC recognizes certain protocol amendments as minor/insubstantial or major/substantial; see TZA-5 for examples of each type. Amendments made to protocols may not be implemented until approved by the NatHREC. Upon receipt of the amendment package, the Secretariat must follow the receiving and validation procedures of submitted protocols. After review of the amendment submission, the Secretariat must determine whether the protocol requires expedited or full review. The amended protocol will be sent to the reviewers of the original submission; in absence of the original reviewers, the Secretariat must appoint and send the amendment application to another reviewer with the same or similar expertise. The number of reviewers will range from one (1) to three (3), depending on the number of the amendments. Minor amendments may be reviewed by members of the Secretariat. If the committee requires modifications to any of the documents, specific changes required must be communicated to the PI with instructions to make the necessary changes and resubmit the documents to the Secretariat. If the committee does not recommend approval of the protocol amendment, this information will be communicated to the MRCC who will review the decision and make the final decision on the approval. If an application is not approved, the PI must be informed of the reasons for not approving the amendment.
Institutional Ethics Committees
Per the G-EthicsHR-TZA, ordinary review is the institution’s normal process for reviewing minimal or more than minimal risk studies. For research that is externally sponsored, the ethical standards should not be less stringent than they would be for research carried out in the country of the sponsoring organization. Local ECs must be fully empowered to disapprove a study they believe is unethical. An EC must require that information given to research participants as part of informed consent complies with the general requirements for informed consent. However, the EC may require that more information be given to the research participants, provided such additional information would meaningfully add to the protection of the rights and the welfare of the research participants. An EC must generally require documentation of the informed consent process. For certain types of research, however, the EC may need the investigator to administer a comprehension test (or test of understanding) to ensure that prospective research participants have acquired adequate knowledge of the relevant facts and consequences of participation in the study. Within 14 days of its review, the EC must notify investigators in writing of the outcome of the research protocol review. If an EC does not approve a research activity, it must include in its written notification a statement of the reasons for its decision.
The G-ResearchIntegrity states that ECs must review protocols in accordance with their standard operating procedures (SOPs) and in a timely and professional manner. Names, titles, and institutional affiliation of reviewers for each proposal will be kept confidential. The decision should be communicated to the investigators in a written letter that is signed or stamped by the EC chair. The letter should include the research/study title as written in the application, the name of the applicant, research site, draft number, date submitted, name and date of EC sitting for that proposal, suggested changes, and a clear statement of final decision by EC. The investigators must notify the EC of protocol amendments, unforeseen circumstances affecting the study, termination of the study, progress reporting, and study termination before or at completion. ECs should also establish monitoring and/or inspection mechanisms for ongoing research projects to ensure compliance with approved criteria.
Expedited Review
As delineated in the G-EthicsHR-TZA, expedited review is a process by which studies that involve no more than minimal risk may be reviewed and approved in a timely manner by an individual EC member or a designated subset of the full EC. Relevant authorities or ECs must establish a list of criteria for protocols that qualify for an expedited review process. Further, relevant authorities or ECs may establish procedures for the expedited review of research protocols, which should specify the following:
- The nature of the applications, amendments, and other considerations that will be eligible for expedited review
- The minimum number of committee members required for expedited review
- The status of decisions (for example, subject to confirmation by a full EC or not)
Accelerated Review
Per the G-EthicsHR-TZA, an accelerated review process may be used for a clinical trial protocol submitted for ethical approval. In reviewing a clinical trial, reviewers may exercise all the authorities of the committee to recommend approval of the submitted protocol. Final approval for protocol is granted in accordance with the standard procedures outlined above. However, applications for accelerated review of clinical trial protocols will be reviewed on a case-by-case basis by the EC, and the applicant may be required to undergo an ordinary review process due to the nature of the trial or else, as determined by the EC.
Continuing Review
As required in the G-EthicsHR-TZA, the EC must conduct additional reviews on approved studies as necessary, particularly if there are significant changes in the protocol that require re-consent by participants or affect the safety of participants, or if other ethical matters emerge during the study. These further reviews include amendments, progress reports submitted by researchers, and possible monitoring of researchers’ compliance with approved protocols. For approved studies, ECs must conduct continuing review of research at intervals appropriate to the degree of risk, but not less than once a year, and must have authority to observe or have a third party observe the informed consent process. The EC must investigate research fraud and take appropriate action where scientific fraud has been suspected or proven.
Suspension or Termination
Per the G-EthicsHR-TZA, the EC has the authority to halt, suspend, or terminate approval of research that is not being conducted in accordance with the EC’s requirements, or research that has been associated with unexpected serious harm to research participants. For example, the EC may suspend research when:
- It finds that the investigator has implemented significant changes in the research protocol without the prior approval of the EC
- The investigator has failed to follow specific procedures or requirements articulated by the EC in its initial review of the research protocol
- When there is severe unexpected harm to the research participants, including, but not limited to, serious physical injury or death
Per the G-EthicsHR-TZA, any suspension or termination of ethics approval must include a written statement of the reasons for the EC’s action. It must be reported promptly to the investigator(s), appropriate institutional officials, and the National Institute for Medical Research (NIMR) Director General.
Multicenter Research
For multicenter research, the G-EthicsHR-TZA states that the study must be conducted in a methodologically identical way at each center, and ECs at individual centers have the authority to adapt the informed consent document provided by the lead institution to make it culturally appropriate. To avoid lengthy procedures, multicenter research within Tanzania should be reviewed by only one (1) EC and other applicable ECs should accept that review. To be informed of the necessary approach, the study team should be consulted. In cases of multicenter research, if a local review committee proposes changes to the original protocol that it believes are necessary to protect the research participants, these changes must be reported to the research institution or sponsor responsible for the whole research program for consideration and possible action. This should ensure that all persons are protected and that the research will be valid across sites. Ideally, review procedures should be harmonized, which may decrease the time needed for review and, accordingly, speed up the research process. Joint reviews may be organized and requested by the study team or sponsor across country borders or institutions in compliance with guidelines. Joint reviews are based on voluntary cooperation between the relevant national regulatory authorities and ECs. In the case of multi-country joint reviews, each country is solely responsible for granting regulatory or ethics approval to the sites within its borders. To harmonize review processes and to maintain sufficient quality of these processes, ECs should develop quality indicators for ethical review.
Exemption
Per the G-EthicsHR-TZA, some studies may be exempt from EC review. If an investigator considers that their research project satisfies the requirements for exemption from ethics review, the EC must ensure that the proposed research satisfies the requirements for exemption from EC review and grant exemption through procedures set by the EC. The following studies may be exempt from EC review:
- Research with negligible risk that involves using existing collections of data or records that contain only non-identifiable data about human beings
- Use of publicly available unlinked data that does not identify individuals or communities
- Use of existing collections of data or records that contain only non-identifiable data about human beings
- Quality assurance/evaluation activities undertaken in the normal course of conducting the business of the institution, i.e., educational assessments, student feedback surveys, audits of organizational activities and systems, and quality assurance reviews
- Emergency use of a test article provided that such emergency use is reported to the EC within five (5) working days; any subsequent use of the test article at the institution is subject to EC approval
- Health systems research if public officials are interviewed in their official capacity on issues that are in the public domain
As indicated in the G-EthicsHR-ZAF, ethics committees (ECs) may independently decide whether to charge fees for a protocol review for external researchers. Researchers without affiliation to an institution or organization with an EC should approach a registered EC to request it to review their health research protocols. If the EC is willing to review external applications, a fee for service may be levied.
National Health Research Ethics Committee
According to the G-TMRCC, the National Health Research Ethics Committee (NatHREC) requires the sponsor, the contract research organization, or the principal investigator (PI) to pay a nonrefundable fee to submit a clinical trial research protocol for ethical review and approval.
As per TZA-17, the fees are as follows:
- Tanzanian researchers, expedited review – 3,875,000 Tanzanian Shillings
- Tanzanian researchers, ordinary review – 2,625,000 Tanzanian Shillings
- Tanzanian researchers, amendment – 750,000 Tanzanian Shillings
- Tanzanian researchers, extension – 300,000 Tanzanian Shillings
- Tanzanian students, expedited review – 390,625 Tanzanian Shillings
- Tanzanian students, ordinary review – 390,625 Tanzanian Shillings
- Tanzanian students, amendment – 250,000 Tanzanian Shillings
- Tanzanian students, extension – 125,000 Tanzanian Shillings
- International researchers, expedited review – $5,125 USD
- International researchers, ordinary review – $2,625 USD
- International researchers, amendment – $750 USD
- International researchers, extension – $300 USD
- International students, expedited review – $548 USD
- International students, ordinary review – $548 USD
- International students, amendment – $375 USD
- International students, extension – $125 USD
See TZA-17 for appeal fees and late renewal penalties.
Payment Instructions
No information is current available regarding payment instructions for the NatHREC.
Institutional Ethics Committees
Institutionally based ethics committees (ECs) may independently decide whether to charge fees for a protocol review. Per the G-ResearchIntegrity, ECs should delineate procedures for the fee structure, mode of payment, and proof of payment in their standard operating procedures (SOPs). Applicants should contact ECs individually for specific fees and payment instructions.
Overview
As stipulated in the NHA, ethics committees (ECs) in South Africa are governed by the National Health Research Ethics Council (NHREC), which is a statutory body established under the NHA. NHREC determines guidelines for the functioning of ECs and registers and audits ECs, among other functions. The NHREC was created by the Minister of Health to provide ethical oversight of clinical research and to safeguard the rights and welfare of human participants involved in clinical studies. According to ZAF-52, NHREC gives direction on ethical issues relating to health and develops guidelines for the conduct of research involving humans and animals. Further, NHREC upholds the principle that research involving human participants is based on a moral commitment to advancing human welfare, knowledge, and understanding, and to exploring cultural dynamics, especially in large-scale trials conducted in developing countries. Of fundamental importance is the duty to conduct scientifically sound research while acting in the participant’s best interests and respecting and protecting the participant’s autonomy.
As delineated in the NHA, the SA-GCPs, and the G-EthicsHR-ZAF, the NHREC’s core responsibilities center on promoting, ensuring, and monitoring compliance by ECs. According to the G-EthicsHR-ZAF and ZAF-52, the functions of the NHREC include:
- Determine guidelines for the functioning of ECs
- Register and audit ECs
- Set norms and standards for conducting research on humans and animals including clinical trials
- Adjudicate complaints about the functioning of ECs
- Refer to the relevant statutory health professional council matters involving the violation or potential violation of an ethical or professional rule by a health care provider
- Institute such disciplinary action as prescribed
- Advise the national department and provincial departments on any ethical issues concerning research
Registration, Auditing, and Accreditation
As delineated in the NHA, the G-EthicsHR-ZAF, and the SA-GCPs, all ECs are required to register with the NHREC in order to undertake the ethical review of a clinical study. Registration information is available on the NHREC webpage (ZAF-12), and a list of ECs currently registered with NHREC is available at ZAF-13. The application to register an EC is at ZAF-53. ZAF-54 states that the EC registration is recorded and publicly listed by the NHREC.
Per the G-EthicsHR-ZAF, the criteria for the NHREC registration assessment and the eligibility audit for ECs are based on the G-EthicsHR-ZAF and other internationally recognized guidelines. Members of the NHREC undertake the assessment and auditing to ensure that ECs comply with capacity and operational requirements. After the first pre-registration audit, guidance and recommendations for improvement are provided with specific timelines for improvements. Before the registration is completed and a registration number is issued, NHREC conducts a follow-up audit to ensure that required revisions have been completed. Voluntary deregistration can occur when an EC is no longer active and closes. A critical part of the ongoing quality assurance review process is the EC annual report form (ZAF-54).
The G-EthicsHR-ZAF states that the NHREC conducts a comprehensive quality assurance assessment and administrative audit of ECs on a five (5)-year cycle to check compliance with the various administrative and record-keeping standards. When an EC persistently fails to comply with expected standards, the NHREC must enforce the standards, e.g., to suspend operations until compliance is achieved or, in extreme cases, to revoke registration of the committee. If an EC is suspended, the NHREC informs the EC of the suspended registration status and outlines the steps to be taken to rectify matters so that a registered status may be reinstated. Capacity evaluation and enhancement for ECs is also an important function of the NHREC. During the period of suspension, the EC concerned may not review new protocols for health research and may not permit another registered EC to review on their behalf. Instead, they should refer applicants to another registered EC. An assessment of the implications for harm to participants will determine whether ongoing monitoring of approved studies is acceptable to the NHREC. Failure by the EC to respond to the required measures to reverse the status of suspended registration can lead to registration being revoked. In this case, a new application for registration is required.
Overview
As mandated by the MedRsrchAct, the National Institute for Medical Research (NIMR) is the central body responsible for oversight, and for the promotion and coordination of research in Tanzania. The NIMR is a semi-autonomous organization under the Ministry of Health (MoH). The IERC-Accredit, the G-EthicsHR-TZA, the G-TMRCC, and TZA-5 state that the NIMR’s Medical Research Coordination Committee (MRCC) serves as the national health research coordinating body, and is responsible for supervising health research in Tanzania. The MRCC, as the NIMR’s clearance body, delegates the registration, review, approval, and monitoring of research to the National Health Research Ethics Committee (NatHREC), which is a subcommittee of the MRCC. The NatHREC focuses on the ethical issues surrounding submitted research proposals. All clinical trial protocols to be conducted in Tanzania are also reviewed by a specialized nine (9)-member Clinical Trials Sub-Committee, which meets monthly and reports to the NatHREC. For detailed information on NatHREC responsibilities, see the G-TMRCC, the G-EthicsHR-TZA, and TZA-5.
TZA-5 acknowledges that not all human subjects research requires review and approval at the national level—i.e., research that does not involve investigational products or collaboration with foreign institutions. For studies that may not need national review, the local ethics committee (EC) must submit quarterly reports listing studies that were approved by the local EC. The NatHREC may request any information related to approved research studies at the institutional level, and ECs are subject to audit.
Registration, Auditing, and Accreditation
Per the G-EthicsHR-TZA, institutions that intend to establish an institutional EC must make a written request to the Director General of NIMR and, upon approval, submit quarterly and annual progress reports to NIMR. In the initial request, the institution must indicate that it will comply with the following minimum requirements:
- A statement of principles governing the institution's discharge of its responsibilities for protecting the rights and welfare of human research participants of research conducted at or sponsored by the institution; this may include an appropriate existing code, declaration, or statement of ethical principles or a statement formulated by the institution itself
- Details on ensuring meeting space availability and sufficient staff and resources to support the EC’s review and record-keeping duties
- A list of members identified by name, qualifications, profession, representative capacity, indicators, or experience such as board certification, and licenses
- Written procedures for monitoring the conduct of studies approved by the EC
As delineated in the IERC-Accredit, institutional ECs may apply for accreditation. Registered and accredited ECs support the NatHREC function of facilitating institutional ethical clearance and monitoring the approved research studies at the level of the institutions to which they belong or are affiliated. ECs are not mandated to approve research protocols for clinical trials and those involving foreign collaborators. These types of research are cleared at the national level only. Following are the EC accreditation assessment criteria:
- Suitability of infrastructure and office space for EC activities
- Adequacy of equipment to support ethics review management
- Adequacy of qualified EC Secretariat staff (technical and support staff) to manage the ethics review procedures
- Appropriateness of the EC governance and structure
- Plan for capacity building/training program for the EC Secretariat, members, and reviewers
- Plan for monitoring of research activities by the EC
- Adequacy of institutional support services
- Appropriateness of EC standard operating procedures (SOPs)
The IERC-Accredit indicates that ECs approved for full accreditation will be published on the NIMR website. The duration of accreditation is three (3) years from the date of notification (certification) by NIMR. Applications for renewal must be made six (6) months before the expiry of the accreditation period. Failure to renew accreditation or failure to maintain the appropriate standards for continuity of accreditation will mean that the accreditation status of the EC will lapse at the end of the current accreditation period and the committee must cease to function. Accreditation must be terminated if NIMR, in consultation with NatHREC, finds that the accredited EC has failed to maintain the required standards. See IERC-Accredit for additional accreditation information, including application procedures and reporting.
See the Tanzania Commission for Science and Technology’s (COSTECH) and the G-ResearchIntegrity for institutional guidance on the introduction and strengthening of research integrity mechanisms. When such mechanisms are well established, institutional ECs can advance to a stage of accreditation.
Overview
As delineated in the SA-GCPs, the sponsor and the investigator must obtain approval from the South African Health Products Regulatory Authority (SAHPRA) and a registered ethics committee (EC) to begin a clinical trial in South Africa. Per ZAF-23, the review and approval of clinical trial applications by SAHPRA and an accredited EC may be conducted in parallel. As indicated in ZAF-20, the same process applies to the review and approval of an amendment to the protocol. However, note that the G-EthicsHR-ZAF recommends that scientific review be completed prior to ethics review and, in cases where scientific review capacity is not available, the EC approval should be delayed until SAHPRA scientific approval has been provided.
Regulatory Submission
Per ZAF-36, researchers must submit a completed application (ZAF-23) and the prescribed fee to SAHPRA on predetermined dates (ZAF-11) and obtain proof of delivery. The proof of delivery, proof of payments, and cover page must be sent to SAHPRA via email. The G-CTA-Electronic delineates the electronic submission and communication process in SAHPRA’s Clinical Trial Unit (CTU). For new clinical trial applications (excluding bioequivalence studies), upon submission at SAHPRA Reception, applicants are requested to alert the CTU via e-mail at ctcresponses@sahpra.org.za and include a copy of the proof of delivery, proof of payment, and proof of insurance. In the subject of the e-mail, the applicant should provide the application type, protocol number, SAHPRA predetermined cycle (see ZAF-11), and email number in case of multiple emails (e.g., “email 1 of 5”). Note that the submission email must include organized zipped folders for various sections of the clinical trial application. Individual site documents for each staff member must be uploaded into one (1) document and labelled with the staff name and arranged in folders according to the site which they belong to.
Per G-CTA-Electronic, to respond to SAHPRA’s screening checklist or to CTU’s expert committee review, the applicant must submit all responses by e-mail to ctcresponses@sahpra.org.za and include labelled attachments to the required documents. In the subject of the email, the applicant should provide the type of application, protocol number, and SAHPRA database tracking number. Responses to the CTU’s expert committee recommendations can be in MSWord or PDF formats. All other accompanying documents should be in PDF format v1.4, 1.5, 1.6, or 1.7 and legible with the Acrobat Reader search plugin or any other freeware viewer. PDF files should be saved as “Optimized” to reduce the size and allow faster opening when viewed online. The use of additional software to navigate and work with the files is not acceptable. If PDF files are not produced from an electronic source document but from scanned paper, readability and file size should be balanced; the following is recommended: resolution 300 dpi (photographs up to 600 dpi), avoid grayscale or color where possible, use only lossless compression techniques. The file must be searchable (OCR scanned). In addition, the maximum size of documents allowed per e-mail is 5 MB. As per arrangement with CTU, in case of a big file of documents and documents that need to be couriered, the waybill should indicate the type of application, protocol number, and SAHPRA database tracking number.
As delineated in the G-CTA-Electronic, for bioequivalence studies, the application and accompanying documents should be emailed to ctcbeprotocols@sahpra.org.za. The clinical trial application form should be in MS Word format and all other accompanying documents in PDF, as described above. As per arrangement with CTU, in case of a big file of documents and documents need to be couriered, the waybill should indicate the type of application, protocol number, and SAHPRA database tracking number. The email subject should include the application type, protocol number, and SAHPRA database tracking number. See the G-CTA-Electronic for specific examples of labeling the emails.
Per the G-CTAPHEmerg, during a public health emergency, applicants should use the modified clinical trial application form in G-CTAPHEmerg. This form recognizes the constraints on the availability of information posed by the emergency. SAHPRA may accept clinical trial applications with reduced information together with a commitment to update and complete the required information as soon as possible. However, all documents submitted must be organized with zipped folders according to the checklist in G-CTAPHEmerg and correctly labelled to ensure easy validation by SAHPRA (See the Submission Content and Emergencies sections for more details).
The G-CTA-Electronic provides instructions on submitting protocol amendments during the conduct of clinical trials, for additional investigators and sites during the conduct of clinical trials, bioequivalence studies, notifications and notification studies, and individual serious adverse events. The applicant must submit to SAHPRA the application for amendment to an approved trial (ZAF-20), as well as notify and get EC approval. (Also see Site/Investigator Selection and Safety Reporting sections for information about these submittal processes.)
The G-CTA-Electronic and ZAF-23 state that the clinical trial application must be sent to SAHPRA in a submission email (per directions above). However, ZAF-1 provides the following address for delivery of clinical trial applications to SAHPRA Reception:
South African Health Products Regulatory Authority
SAHPRA Reception – 2nd floor
Loftus Park, Building A
402 Kirkness St, Arcadia
Pretoria, 0007
South Africa
Per ZAF-1, upon receipt of the clinical trial application at SAHPRA Reception, an acknowledgement of receipt in the form of a stamp and signature will be issued. The waybill from a courier company does not suffice as proof of delivery. SAHPRA’s CTU requires a document, referred to as the ‘stamp page,’ which includes the SAHPRA trial reference number, protocol number, and study title. This document will then be date-stamped and signed by SAHPRA’s Administrative Department and returned as proof.
As per the GRMRSA, all applications and supporting data submitted to the SAHPRA should be presented in English. Original documents that are not in English must be accompanied by an English translation.
Ethics Review Submission
Each EC has its own required submission procedures, which can differ significantly regarding the number of copies to be supplied and application format requirements. Refer to each EC’s website for specific submission procedures.
Overview
According to the TMMDAct, the CT-Regs, and the G-AppConductCT, the Tanzania Medicines and Medical Devices Authority (TMDA) requires the sponsor, the designated contract research organization (CRO), or the investigator to obtain TMDA approval. Per TZA-5, the principal investigator (PI) is required to submit an application for ethical review of a research study to the national ethics committee (EC), the National Health Research Ethics Committee (NatHREC). All clinical trials must get ethics approval from both the institutional EC and the NatHREC. TZA-18 states that if there is no institutional EC available, the approval must be obtained from NatHREC. According to the G-AppConductCT and TZA-4, TMDA and NatHREC reviews may be conducted in parallel. However, the TMDA application must include a copy of the NatHREC's acknowledgement of receipt for the study protocol. In addition, the TMDA's approval will only be finalized once NatHREC approval is obtained.
Per the G-ResearchClearance, the Tanzania Commission for Science and Technology (COSTECH) must review and approve all research in Tanzania.
Regulatory Submission
Tanzania Medicines and Medical Devices Authority
Per the G-AppConductCT, applicants must submit both paper and electronic copies of the clinical trial application (CTA). Per TZA-4 and TZA-36, electronic CTAs must be completed online via the Regulatory Information Management System (RIMS) Customer Self Service Portal (TZA-34). Applicants must fill out CTAs as per the Modules and the Common Technical Document (CTD) highlighted in the G-AppConductCT. Applications for amendment(s) to a previously authorized clinical trial must be submitted on the applicable form in RIMS. The clinical trial application form is available at TZA-38, and the application forms for protocol amendments are at TZA-43 and TZA-44. Note that a list of clinical trial forms is posted to TZA-35.
Per the G-AppConductCT, the hard copy of the application may be delivered in person or by courier to the TMDA at the following address:

ZAF-20 delineates the contents and requirements for submitting an application for protocol amendment to an approved clinical trial.
Per the G-CTAPHEmerg, SAHPRA states that during a public health emergency, new and experimental treatments may become necessary and clinical trials are essential to provide the evidence to develop appropriate policies for patient treatments. Under these circumstances, there may be limited information available. However, applications need to contain a certain minimum of information to enable a meaningful evaluation and regulatory decisions. To address this, SAHPRA provides an information grading system in the G-CTAPHEmerg wherein required information is labelled. Applicants must attempt to provide the information listed below and justify when this is not available. The required information is graded as follows:
- Essential – Application will not be considered without this
- Important – Necessary information that must be provided later and must be justified if not available
- Not essential – May be omitted from this preliminary application
All incomplete information must be explained, justified, and provided to SAHPRA as a complete application (ZAF-23), when available. This means that repeat evaluations of an application may be necessary.

Overview
Based on ZAF-23 and the SA-GCPs, the review and approval of clinical trial applications by the South African Health Products Regulatory Authority (SAHPRA) and an accredited ethics committee (EC) may be conducted in parallel. The applicant must notify each regulatory body of the other’s approval once it has been received. However, note that the G-EthicsHR-ZAF recommends that scientific review be completed prior to ethics review and, in cases where scientific review capacity is not available, the EC approval should be delayed until SAHPRA scientific approval has been provided. Also, where site permissions are required, e.g., from Provincial Health Research Committees (PHRCs) or superintendents, to conduct research in health care facilities, ECs must delay granting full approval until these permissions are received to prevent research from beginning before the facility knows it will happen.
Regulatory Authority Approval
In general, per ZAF-36, SAHPRA’s Clinical Trial Unit (CTU) aims to process new applications and issue a screening checklist within three (3) weeks of receipt. After that, the expert Clinical Trials Committee (CTC) recommendations will be sent within 10 weeks of the submission due date. There are cases where this turnaround time might be prolonged, such as an unfamiliar investigational product which may be referred to external reviewers or other SAHPRA committees for input.
Per ZAF-1, during the preliminary screening, the CTU screens the application and sends an official letter to the applicant with the outcome and follow-up questions on a screening checklist. The applicant receives the screening checklist within 15 working days after application submission. The applicant must respond within seven (7) working days after receipt of the screening review.
Next, the CTC reviews the proposed clinical trials. ZAF-11 provides the dates of the 2025 CTC meetings and the SAHPRA submission due dates. It is advisable to submit clinical trial applications before these due dates. Once the reviewer approves the application, the CTC presents the committee’s/reviewer’s recommendations to the SAHPRA. ZAF-1 states that applicants receive a response within 10 working days from the CTC meeting, and they must send an answer within seven (7) working days after receipt of comments. If an applicant would like to request a meeting with the CTC, the request should be submitted through the SAHPRA Chief Executive Office pursuant to the procedures in the G-ConsultMtg.
Ethics Committee Approval
Review timelines vary per each EC’s procedures. The G-EthicsHR-ZAF states that ECs must define the review timelines in their standard operating procedures.
Overview
Based on the TMMDAct, the CT-Regs, and the G-AppConductCT, the Tanzania Medicines and Medical Devices Authority (TMDA)'s approval of a clinical trial application is dependent upon obtaining proof of ethical approval from the national ethics committee (EC), the National Health Research Ethics Committee (NatHREC). According to the G-AppConductCT, TMDA and NatHREC reviews may be conducted in parallel. However, the TMDA application must include a copy of the NatHREC's acknowledgement of receipt for the study protocol. In addition, the TMDA's approval will only be finalized once NatHREC approval is obtained. As per the G-ResearchClearance, after receiving TMDA and NatHREC approvals, the researcher must submit an application for research clearance to the Tanzania Commission for Science and Technology (COSTECH).
Regulatory Authority Approval
Tanzania Medicines and Medical Devices Authority
According to the G-AppConductCT, the TMDA review process is conducted on a first-in, first out basis. The TMDA will evaluate complete applications within 60 working days of receiving the application. The fast-track evaluation provides that a new clinical trial application may be fast tracked and assessed within 30 working days of its submission if the applicant has requested and paid twice the prescribed clinical trial application fee. The CTC-Time validates the timelines in the G-AppConductCT.
As set forth in the TMMDAct, the CT-Regs, and the G-AppConductCT, the TMDA coordinates the clinical trial application process. Upon receipt of a clinical trial application, the TMDA initially screens the application for completeness. If complete, the TMDA officer acknowledges receipt of the application by returning a signed copy of the cover sheet to the applicant (see Annex 1 of the G-AppConductCT or First Schedule of the CT-Regs). Per the G-AppConductCT, the TMDA may request clarification, certificates, and/or samples through a query letter. Once a query has been raised and sent to the applicant, the evaluation process stops until the TMDA receives a written response to the query. The response should be submitted within six (6) months after the query letter was issued. In addition, TMDA reserves the right to request information or set conditions not specifically described in the G-AppConductCT to allow it to adequately assess the safety, efficacy, or quality of an investigational product (IP). If authorization is not granted, an appeal may be submitted to the TMDA within 60 days of the TMDA’s decision. If no appeal is submitted by the applicant within this period or, if after consideration of any comments submitted, the TMDA is still not satisfied, it must reject the application.
The TMMDAct states that the TMDA Director General must issue a Clinical Trial Certificate to authorize the trial to be conducted. Per the G-AppConductCT, the TMDA’s clinical trial authorization will be valid up to the proposed duration of the study indicated in the application. However, the validity will not extend beyond five (5) years. If the trial needs more than five (5) years, the applicant must request an extension. If granted, the TMDA will issue an updated certificate.
Tanzania Commission for Science and Technology
The G-ResearchClearance indicates that once COSTECH receives a new application, the Secretariat screens the application for completeness; registers the application; and sends an acknowledgement to the applicant within five (5) business days. If approved after COSTECH’s review, the principal investigator (PI) is then required to collect the research permit certificate from COSTECH. Per TZA-47, COSTECH’s review committee meets every two (2) months, and applicants are advised to apply two (2) months before the research commencement date.
Ethics Committee Approval
National Health Research Ethics Committee
As set forth in the G-TMRCC and TZA-5, the NatHREC meets once a month to evaluate application submissions. TZA-5 indicates an e-mail notification acknowledging receipt and successful validation of the clinical trial application must be sent to the PI or applicant by NatHREC within two (2) working days from the date of receipt. Comments from reviewers will reach the PI within two (2) days through the Research Ethics Information Management System (REIMS) (TZA-32) (also referred to as the National Health Research Management Information System (NHRMIS)), depending on the type of study protocol. If the PI or applicant fails to respond to the committee’s and reviewers’ comments within 30 days, the NatHREC Secretariat must notify the PI of intent to remove the protocol from the REIMS. For clinical trials applications, reviewers’ comments and the outcome of the NatHREC meeting must be forwarded to the PI within 30 days from the date of acceptance by the NatHREC. A PI may appeal that decision in writing to the Medical Research Coordination Committee (MRCC) Chairperson within 30 days of receipt of the decision. The MRCC will respond to PIs in writing within 30 days or upon scrutiny of the appeal. The MRCC Chairperson may invite the PI to appear in person to the MRCC within 30 days of receiving the written appeal. For protocol reviews during public health events of national and/or international concern, protocols should be sent to reviewers within 24 hours of submission by the Secretariat. Reviewers should complete their reviews within three (3) days. The consolidated review and suggested revisions (or approval) should be communicated to the PI(s) within five (5) days. The PI should respond to the review notification within 48 hours.
Per TZA-18, the whole process of receiving, reviewing, and approving the protocols takes a maximum of six (6) weeks.
Institutional Ethics Committees
According to TZA-5, the institutional EC review may occur prior to the proposal review by the NatHREC as the application to the NatHREC requires an EC approval certificate from an affiliated institution(s), where applicable (i.e., for foreign sponsors and when an institution has an EC). As required in the G-EthicsHR-TZA, the EC must notify investigators in writing of the review decision within 14 days of its review.

In accordance with the GRMRSA, the SA-GCPs, the G-EthicsHR-ZAF, and the NHAParticipants, a clinical trial can only commence in South Africa once an applicant receives approval from the South African Health Products Regulatory Authority (SAHPRA) and from a registered ethics committee (EC). There is no waiting period required following the applicant’s receipt of these approvals. Note that the G-EthicsHR-ZAF recommends that scientific review be completed prior to ethics review and, in cases where scientific review capacity is not available, the EC approval should be delayed until SAHPRA scientific approval has been provided. Also, where site permissions are required, e.g., from Provincial Health Research Committees (PHRCs) or superintendents, to conduct research in health care facilities, ECs must delay granting full approval until these permissions are received to prevent research from beginning before the facility knows it will happen.
The trial must be conducted in compliance with the SA-GCPs, the G-EthicsHR-ZAF, and the GRMRSA. Also, per the SA-GCPs, all clinical trials must be conducted in a laboratory complying with Good Laboratory Practices (GLP). See ZAF-2 for the World Health Organization (WHO)’s handbook on GLPs.
Per the SA-GPPs, pharmacists must be involved in clinical trials, including for example, assisting in the development of protocols, overseeing medicine supplies, monitoring administration protocols, and maintaining registries. According to the SA-GCPs, the sponsor must also define and allocate all study related duties and responsibilities to the investigator prior to initiating the study.
Clinical Trial Agreement
According to the SA-GCPs, all parties involved in the conduct of a trial should be familiar with guidance in the International Council for Harmonisation's Guideline for Good Clinical Practice E6(R2) (ZAF-27) and other international guidelines. All clinical trials should be conducted in accordance with all ethical principles outlined in the Declaration of Helsinki (ZAF-44). Before the trial begins, a sponsor must prepare a written agreement. The agreement must be signed by the sponsor and the PI, and any other parties involved (e.g., institutions and contract research organizations) with the trial to confirm the contract terms. Both the sponsor and the PI must commit to providing safety information between each other. The sponsor should also obtain the investigator's agreement to:
- Conduct the trial in compliance with the SA-GCPs, the SAHPRA requirements, ZAF-27, and the EC approved protocol
- Comply with data recording/reporting procedures
- Permit monitoring, auditing, and inspection
- Retain the trial-related essential documents until the sponsor informs the investigator(s) and institution(s) that these documents are no longer needed
In addition, per the SA-GCPs, the financial aspects of the trial should be documented in the agreement. A declaration must be signed by the sponsor and PI stating that sufficient funds are available to complete the study. The sponsor is also responsible for securing agreements to ensure direct access to all trial-related sites, source data/documents, and reports for the purpose of monitoring and auditing by the sponsor, and inspection by domestic and foreign regulatory authorities.
Clinical Trial Registration
According to the SA-GCPs, NHAParticipants, and ZAF-32, the PI or the sponsor must enter the trial information in the South African National Clinical Trials Register (SANCTR) (ZAF-48). The G-EthicsHR-ZAF states that solely the sponsor must register all South Africa-based trials on SANCTR, and if the trial has no commercial sponsor, the PI must register the trial. According to the SA-GCPs, the National Department of Health (NDOH) then issues a unique SANCTR National Register Number. ZAF-32 has instructions for registering either online or via email.
ZAF-48 states that SANCTR fulfills the requirements of the International Committee of Medical Journal Editors (ICMJE) publication mandates and has a formal partnership with the Pan African Clinical Trials Registry (ZAF-50), which is recognized by the WHO.
Governance
The G-EthicsHR-ZAF explains that research, especially that using state or provincial facilities and resources, should link to health care system priorities, and findings should be integrated into policy planning and management of health programs. PHRCs were established to liaise with researchers to ensure that the greatest health needs of each province are being addressed. As such, they perform a gate-keeping role by managing access to health facilities. While they accept ethics approval granted by a registered EC, they need to consider applications to use their facilities to manage potential interference with or interruption of services. It is thus important that PIs respect this role of the PHRCs. Some provinces have also registered provincial ECs, and these committees are important in areas of the country where other ECs are not active.
Overview
In accordance with the TMMDAct, the CT-Regs, and the G-AppConductCT, a clinical trial can only commence after an applicant receives permission from the Tanzania Medicines and Medical Devices Authority (TMDA) and approval from the national ethics committee (EC), the National Institute for Medical Research (NIMR)’s National Health Research Ethics Committee (NatHREC). Per the G-ResearchClearance, following TMDA and NatHREC approvals, the applicant must also apply to the Tanzania Commission for Science and Technology (COSTECH) for review, registration, and to obtain a research permit prior to initiating a study. No waiting period is required following the applicant’s receipt of these approvals.
In addition, as per the TMMDAct, the CT-Regs, the TFDCA-ImptExpt, and the G-AppConductCT, the sponsor or the principal investigator (PI) is required to obtain an import license for the shipment of an investigational product to be used in the trial. (See the Manufacturing & Import section for additional information).
Clinical Trial Agreement
Prior to the trial’s commencement, the G-AppConductCT specifies that the protocol must be dated and signed by the investigator, the host institution, and the sponsor, and can function as a contract. In addition, as per the G-CTInsurance-TZA, a clinical trial agreement must be signed by the chief executive of the host institution, the sponsor, and the PI. G-EthicsHR-TZA also states that the PI must sign the protocol and holds primary responsibility for managing and ensuring the integrity of the research study from initiation to finalization.
Per the G-AppConductCT, the sponsor and researchers are required to conduct the clinical trial in compliance with applicable Tanzanian laws and regulations and the International Council for Harmonisation's Guideline for Good Clinical Practice E6(R2) (TZA-13). TZA-13 states that the sponsor is responsible for obtaining agreement from all involved parties to ensure direct access to all trial related sites, source data/documents, reports for monitoring and auditing purposes, and inspection by domestic and foreign regulatory authorities. Quality control should be applied to each stage of data handling to ensure that all data are reliable and have been correctly processed. A written agreement must be signed by both the sponsor and the investigator, or any other parties involved with the clinical trial, verifying that both parties agree to the trial protocol, the monitoring and auditing practices, the standard operating procedures (SOPs), and their respective duties. The sponsor must also obtain the investigator(s)’ and the institution(s)’ agreement to:
- Conduct the trial in compliance with TZA-13, applicable regulatory requirement(s), and the protocol agreed to by the sponsor and approved by the EC
- Comply with data recording and reporting procedures
- Permit monitoring, auditing, and inspection
- Retain essential documents until the sponsor indicates that they are no longer needed
Also, per the CT-Regs, the sponsor must ensure that all agreements made with the PI and any other parties involved in a clinical trial are in writing, as part of the protocol or in a separate agreement.
Clinical Trial Registration
As per the CT-Regs and the G-AppConductCT, all clinical trials taking place in Tanzania must be registered with the Tanzania Clinical Trials Registry (TzCTR) which is accessed via the Regulatory Information Management System (RIMS) Customer Self Service Portal (TZA-34). An applicant must submit detailed clinical trial information to the TzCTR not later than 21 days after the first participant is enrolled in the trial. See the CT-Regs for complete registry submission requirements. The G-AppConductCT further stipulates that applicants have the option to register in any other publicly accessible registries accepting international clinical trial information and recognized by the World Health Organization (WHO). The registration number should be made available to the TMDA.
Safety Reporting Definitions
In accordance with the SA-GCPs and the G-SafetyRpt, the following definitions provide a basis for a common understanding of South Africa’s safety reporting requirements:
- Adverse Event/Experience (AE) – Any untoward medical occurrence that may present during treatment with a medicine, but which does not necessarily have a causal relationship with this treatment
- Adverse Drug Reaction or Adverse Reaction (ADR) – A noxious and unintended response to a medicine in humans or animals, including lack of efficacy, and which occurs at any dosage and can also result from overdose, misuse, or abuse of a medicine
- Serious Adverse Event (SAE) or Serious Adverse Drug Reaction (SADR) – Any untoward medical occurrence that at any dose: results in death, is life-threatening, requires patient hospitalization or prolongation of existing hospitalization, results in persistent or significant disability or incapacity, or is a congenital anomaly or birth defect
- Unexpected Adverse Drug Reaction – One in which the nature, specificity, severity, and outcome is inconsistent with the applicable product information (i.e., with the approved package inserts for registered medicines, the investigator’s brochure, or other product information for unregistered medicines being used)
The G-EthicsHR-ZAF defines SAE as an unforeseen harmful event related to the study (e.g., injury/death due to an experimental intervention), thereby negatively affecting the research participants and requiring an intervention.
Per the G-EmergencyProc, all clinical trial sites must have an emergency standard operating procedure that should be available for inspection by the South African Health Products Regulatory Authority (SAHPRA). In addition, each clinical trial site should have adequately trained investigators to manage medical emergencies. Further, there must be an emergency 24-hour contact number for trial participants who experience an unexpected AE.
Safety Reporting Requirements
Investigator Responsibilities
As specified in the SA-GCPs, the principal investigator (PI) must inform the sponsor immediately, or within the time specified in the protocol, of any serious and/or unexpected AEs occurring during the study. The initial reporting form and any relevant follow-up information should be sent to the sponsor. The G-SafetyRpt directs the investigator to report AEs to the sponsor in a manner defined in the protocol. Per the SA-GCPs, AEs and/or laboratory abnormalities identified in the protocol as critical to safety evaluations must be reported to the sponsor in accordance with the reporting requirement and within the time periods specified in the protocol. In the case of participant deaths, the PI must supply the sponsor, the ethics committee (EC), and SAHPRA with any additional information, as requested. The initial and follow-up reports must identify the affected participants by the participant identification code.
Per the G-EthicsHR-ZAF, researchers are expected to provide appropriate information to the EC to facilitate monitoring, including alerts. If an EC conducts a site visit, the evaluation should include inspecting documentation of AEs and SAEs. In addition, ECs should request regular, at least annual, reports from PIs on matters including a list of all AEs in the past 12 months.
Sponsor Responsibilities
As delineated in the GRMRSA, the sponsor is required to report all expected or unexpected SAEs/SADRs on an expedited basis to all concerned parties, including the investigator(s) and institution(s), the SAHPRA, and the ECs. Pursuant to the G-SafetyRpt, the sponsor is required to submit the following safety reports to SAHPRA:
- Reports of SUSARs occurring in the clinical trial using the SAHPRA SAE form (ZAF-19), CIOMS form (ZAF-15), or Annex B of G-SafetyRpt
- Reports of all SUSARs and trends occurring with the investigational product (IP) in South Africa
- Six-month progress report
- Annual Development Safety Update Reports (DSURs) that include information gathered from all clinical experience with the IP, whether in South Africa or elsewhere
- Final Progress Report
- Final Study Report
The SA-GCPs states that the sponsor is responsible for performing an ongoing safety evaluation of the IP and must promptly provide written notification to the investigator and SAHPRA of findings that may adversely affect the safety of participants or the conduct of the trial, and/or change the EC's approval to continue the trial. The commitment to provide safety information must be included in the clinical trial agreement signed between the sponsor and the investigator.
The G-SafetyRpt delineates the following reporting timeframes:
- The sponsor should initially report all fatal or life-threatening SAEs in local reports within seven (7) calendar days after first knowledge, using CIOMS format (ZAF-15)/SAHPRA SAE form (ZAF-19). The follow-up report should be submitted within an additional eight (8) calendar days.
- All fatal or life-threatening SAEs in foreign reports should initially be reported within 30 calendar days after first knowledge by the sponsor. The follow-up report should be submitted within an additional six (6) months as part of the progress report. If the SAEs result in premature study closure, the reporting times are shorter—seven (7) days for the initial report and within an additional eight (8) days for the follow-up report. These reports should be in a line listing format. Note that these reporting requirements also cover foreign reports of “special concern,” which is a significant safety issue defined for each clinical trial that requires urgent attention from the regulatory authority. An adverse reaction of special concern from a foreign jurisdiction should be based on the decision of its regulatory authority. A safety issue leading to international regulatory action is considered to be significant at all times and hence reportable.
- Local reports of other serious events (unexpected, not fatal or life threatening) within 15 calendar days of the event and every six (6) months in the CIOMS format (ZAF-15)/SAHPRA SAE form (ZAF-19)
- A line listing of all local reports—serious (unexpected and expected) AEs—and any other issues of special concern outside South Africa should be submitted every six (6) months (using the progress report form in ZAF-18).
- An initial detailed report of new information impacting the risk-benefit profile of the IP or conduct of trial should be submitted within three (3) calendar days; a follow-up report should be submitted within an additional six (6) months.
- An initial detailed report of other major safety concerns (e.g., changes in nature, severity, or frequency of risk factors) should be submitted within 15 days of knowledge of the concern; a follow-up report should be submitted within an additional six (6) months.
- DSURs should be submitted within one (1) year from approval of the study and annually thereafter.
In addition, SAHPRA reserves the right to impose additional reporting timelines on an individual protocol basis, and it may require expedited reporting of AEs of special interest, whether serious or not.
See the G-SafetyRpt for details on the contents of the reports and other safety report requirements.
Form Completion & Delivery Requirements
Per the G-SafetyRpt and ZAF-19, the SAHPRA’s Safety Reporting During Clinical Trials Form (ZAF-19) should be used to complete SAE/ADR reports—for both initial and follow-up safety reports. The G-SafetyRpt indicates that adverse drug reactions occurring during post-marketing studies (Phase 4 and observational studies) should be reported to the Vigilance Unit of SAHPRA, and adverse drug reactions occurring during the use of concomitant and/or comparator medicine in a clinical trial should be reported to the Clinical Trial Unit of SAHPRA. Reportable safety information must be sent to:
- ctcsaes@sahpra.org.za for clinical trials (per ZAF-47, ctcsaes@sahpra.org.za should be used for individual patient SAEs and related queries)
- adr@sahpra.org.za or e2b@sahpra.org.za for post-marketing studies
- section21@sahpra.org.za for reporting of SAEs for medicines used under Section 21
As per ZAF-47, the following is the contact information for pharmacovigilance-related submissions:
- ADR reports in an e2b in an xml format: e2b@sahpra.org.za
- All other ADR reports: adr@sahpra.org.za
- Pharmacovigilance related queries: pvqueries@sahpra.org.za
- Documentation relating to identified safety concerns, responses to recommendations, and Risk Management Plans (RMPs): pvsubmissions@sahpra.org.za
G-CTA-Electronic details the requirements for electronic submission of individual SAEs. All SAEs should be submitted to ctcsaes@sahpra.org.za with a cover letter detailing:
- The title of the study
- The SAHPRA reference number
- Protocol number
- Name of site
- Patient study ID
- Cause of SAE
- Causality and SAE reporting form
- Other applicable information
The email subject line should include the following information: SAE, protocol number, and SAHPRA database tracking number.
Safety Reporting Definitions
In accordance with the CT-Regs, the G-ReptSafetyData, and the G-AppConductCT, the following definitions provide a basis for a common understanding of Tanzania’s safety reporting requirements:
- Adverse Event (AE) – Any adverse medical occurrence in a research participant to whom a drug product was administered, and which does not necessarily bear a causal relationship to the treatment
- Adverse Drug Reaction (ADR) – All noxious and unintended responses to a medicinal product related to any dose
- Serious Adverse Event (SAE) or Serious Adverse Drug Reaction (SADR) – Any untoward medical occurrence that at any dose: results in death, is life threatening, requires hospitalization or prolongation of existing hospitalization, results in persistent or significant disability/incapacity, or is a congenital anomaly/birth defect
- Suspected Unexpected Serious Adverse Reaction (SUSAR) (also referred to as Unexpected ADR) – A serious adverse reaction where the nature and severity of the event is not consistent with the medicinal product
The PV-Regs reaffirms that the reporting of SAEs and SUSARs occurring during clinical trials should comply with the requirements in the CT-Regs.
Per the G-EthicsHR-TZA, the severity of an AE must be graded as follows:
- Mild: Includes events that do not interfere with activities of daily living and do not require treatment
- Moderate: Includes events that have minimal effect on activities of daily living and usually require out-patient treatment
- Severe: Includes activities that significantly affect activities of daily living and may require inpatient hospitalization
- Life-threatening: Includes all events that are life threatening and usually require emergency procedures
- Death
The G-EthicsHR-TZA states that an AE must be deemed unexpected if:
- It is previously unobserved or undocumented in humans under the health research intervention (or one substantially similar)
- The nature or severity is not consistent with information in the investigator’s brochure or other safety information known at the time
- The event is observed with higher frequency or severity than previously documented
See the G-EthicsHR-TZA for additional details on grading AEs.
Safety Reporting Requirements
Investigator Responsibilities
As stated in the G-ReptSafetyData and the G-AppConductCT, the investigator is responsible for documenting and reporting all AEs/ADRs, SAEs/SADRs, and SUSARs to the sponsor using the case report form (CRF)/reporting form and the SAE/SADR Reporting Form approved in the protocol, or CIOMS Form I (TZA-7). See section 3.0 of the G-ReptSafetyData for key data elements to include on the form. TZA-5 requires the principal investigator (PI) to ensure that the protocol includes all required elements for safety monitoring, including assessment and reporting of any anticipated or unanticipated AEs and SAEs. Ethics committees (ECs) (both the National Health Research Ethics Committee (NatHREC) and institutional ECs) must review and address AEs, SAEs, and/or SUSARs. Investigators must be familiar with the regulations, policies, and procedures concerning reporting and continuing review requirements, as well as timelines for submission of notifications and reports.
The CT-Regs states that the PI must immediately report to the Tanzania Medicines and Medical Devices Authority (TMDA) any SAE/SADR that occurs to a participant at a trial site where the PI is responsible for the conduct of the trial. The report may be made orally or in writing and must be followed up with a written report in 14 days. Also, the PI must report AEs that the protocol identifies as critical to safety evaluations. The reports must identify each participant by a number assigned to that participant in accordance with the protocol.
The CT-Regs further states the PI or sponsor must record and report SUSARs that are fatal or life-threatening to the TMDA within seven (7) days and other SUSARs within 15 days.
The G-EthicsHR-TZA requires the investigator to promptly investigate all SAEs, take appropriate measures to ensure the safety of all research participants, and report these and any other information that is likely to affect the safety of the research participants or the conduct of the research events, to the regulatory authority, institutions, and sponsor within the timelines stated in standard operating procedures. Specifically, the investigator must report the following to the EC and TMDA:
- All SAEs irrespective of relationship to the health-related intervention
- All unexpected events of greater than moderate severity irrespective of relationship to health-related intervention
- All events associated with protocol violations irrespective of severity and relationship to health-related intervention
- When criteria for stopping or pausing a study as stipulated in the protocol are met
- Any event mandated by regulatory authorities
- Any event stipulated in the protocol as reportable to the regulatory bodies
Per the G-EthicsHR-TZA, all SAEs must be reported to the local EC as soon as possible and in any case no later than seven (7) days of becoming aware of the event. Thereafter, a detailed report of the SAE should be submitted within eight (8) days. All other reportable AEs should be reported to the EC as soon as possible and in any case not later than 15 days. TZA-5 requires the investigator to submit an initial report on an SAE to NatHREC within 24 hours of its occurrence and a final or followup report on the SAE within 14 days of its occurrence.
Further the G-EthicsHR-TZA requires the investigator to clearly outline in the protocol how management of both foreseeable and unforeseeable AEs will be done. Certain categories of interventions whose long-term effects are not known or cannot be extrapolated will require extended monitoring for AEs, such as genetically modified substances, gene therapy, and DNA-based therapies.
Sponsor Responsibilities
The G-ReptSafetyData states that the sponsor is responsible for the assessment and timely reporting of SAEs/SADRs and SUSARs to the TMDA. The sponsor must retain detailed records of safety information reported by the investigator(s) and ensure that all reports required by the TMDA are submitted on time. In addition, the sponsor must report all SAEs and SUSARs occurring from trial sites outside the country to the TMDA.
The G-ReptSafetyData requires that fatal or life-threatening SAEs/SADRs or SUSARs must be immediately reported to the TMDA by telephone, fax, or email followed by a complete report within seven (7) additional calendar days. The G-AppConductCT specifies that the immediate reporting period is within 24 hours. Further, the report should include an assessment of the importance and implication of the findings, including relevant previous experience with the same or similar products. All deaths during the study, including the post-treatment, follow-up period, and deaths that resulted from a process that began during the study, should be reported.
Per the G-ReptSafetyData and the G-AppConductCT, all other SAEs and SUSARs that are not fatal or life-threatening must be filed as soon as possible but no later than 14 calendar days after first knowledge by the sponsor. Please note that the CT-Regs states that non-life-threatening SUSARs should be reported in 15 days.
See the CT-Regs and the G-ReptSafetyData for detailed reporting requirements.
Form Completion & Delivery Requirements
As per the G-ReptSafetyData and the G-AppConductCT, all SAEs/SADRs and SUSARs must be reported on the protocol-approved CRF/reporting form, or CIOMS Form I (TZA-7), and should include trial specific details such as participants’ ID numbers and/or protocol number. The form must be submitted to the TMDA office by courier, mail, email (as an attachment), or by fax.
According to TZA-26, the TMDA address and contact information is as follows:
P.O. Box 1253, Dodoma or P.O. Box 77150, Dar es Salaam, Tanzania
Telephone: +255 22 262961989 / 262961990
Fax: +255 22 2450793
Email: info@tmda.go.tz
See Annex 15 of the G-AppConductCT and Appendix 1 of the G-ReptSafetyData for the reporting forms.
Interim and Annual Progress Reports
In accordance with the GRMRSA, the person authorized by the South African Health Products Regulatory Authority (SAHPRA) to conduct a clinical trial (i.e., the sponsor) must submit progress reports to the SAHPRA every six (6) months from the application approval date. The SA-GCPs requires the investigator to submit written progress reports to the ethics committee (EC) annually and to the SAHPRA every six (6) months. ECs and the SAHPRA may request reports more frequently. The G-EthicsHR-ZAF states that ECs should request regular, at least annual, reports from principal investigators (PIs) on matters including: progress; current enrolment status; whether participant follow-up is still active or completed; record maintenance and security; evidence of compliance with the approved protocol and any conditions of approval; negative reports from monitors or good clinical practice (GCP) inspectors; all adverse events in the past 12 months; and all amendments made in the past 12 months.
Per the GRMRSA, the SA-GCPs, and G-SafetyRpt, the six-month report (ZAF-18) must include the following (Note: Each of the items listed below will not necessarily be found in all sources, which provide overlapping and unique elements):
- SAHPRA database tracking number
- Study title
- Protocol number
- Details of the sponsor
- Progress to date or the outcome in case of completed research
- Whether participant follow up is still active or has been completed
- List of all active trial sites, addresses, and PIs
- Trial information, including date of approval of study, treatment hold (if applicable), and expected date of completion
- Number of participants per site and current enrollment status
- Sponsor comment on progress to date
- Summary of Data Safety Monitoring Board or Safety Committee recommendations and relevant safety data
- Serious adverse events and suspected unexpected serious adverse reactions for all participants per site in South Africa, including identification of previous safety reports submitted to the SAHPRA concerning a similar suspected adverse reaction and an analysis of their connection
- Any safety issues of special concern outside of South Africa
- Line listing of all critical and major protocol violations/noncompliance and resolutions/actions taken at a site or conditions of approval
- PI comment on other major safety concerns
- Signature of the PI
- Signature of the sponsor
Note that the SA-GCPs directs the investigator to promptly provide written reports to the sponsor/applicant, the EC, and where applicable, the institution on changes that significantly affect trial conduct and/or increase the risk of participant harm.
Final Report
The sponsor is required to submit a final progress report to the SAHPRA 30 days following the trial’s completion as stated in the GRMRSA and the G-SafetyRpt. Further, per G-SafetyRpt, a final study report should be submitted within 180 days of clinical trial completion or termination.
In addition, per the SA-GCPs, upon the trial’s end, the investigator must inform the institution (if applicable), the EC, and the SAHPRA and provide them with a summary of the trial outcome and other required reports.
The G-EthicsHR-ZAF states PIs or research leaders must disseminate research results or findings, whether positive or negative, in a timely, accessible, responsible, and competent manner. This includes reporting back to participant communities where appropriate.
The SA-GCPs specifies that the sponsor must ensure that trial results and outcomes are reported to the investigators, the SAHPRA, and the National Department of Health (NDOH) via the South African National Clinical Trials Register (SANCTR) (ZAF-48) within one (1) year of the study’s completion. The sponsor and the PI are responsible for appropriate dissemination of the trial findings.
Interim and Annual Progress Reports
As delineated in the G-AppConductCT, the sponsor or the principal investigator (PI) must submit progress reports to the Tanzania Medicines and Medical Devices Authority (TMDA) on a six (6)-month basis from the date of the clinical trial’s commencement. The content should be as prescribed in TZA-11. In addition, the TMDA provides a six (6)-month progress report form for clinical trials of investigational products (TZA-3). The CT-Regs states that progress reports should be submitted annually, or more frequently, as required by the TMDA.
Per the G-EthicsHR-TZA, researchers must submit progress reports to the ethics committee (EC). The investigator must ensure appropriate and timely feedback on the research process including progress reports at regular intervals as stipulated by the EC. Periodic progress reports enable the EC to determine whether the research study is progressing according to the approved protocol.
According to TZA-5, the investigator must submit written progress reports every six (6) months to the National Health Research Ethics Committee (NatHREC) for all ongoing approved health research activities in Tanzania.
In addition, per the G-ResearchClearance, the PI is required to submit annual progress reports (as part of the annual permit-renewal process) to the Tanzania Commission for Science and Technology (COSTECH) that include the title of the study, COSTECH registration reference number, study site, brief background and objective of the study, progress in the reporting period, any problems encountered, and implementation plan for the next period.
Final Report
The G-AppConductCT requires the sponsor or the PI to submit a closing report to the TMDA within 60 days of the trial’s completion. This report should be followed by a final study report within six (6) months after trial closure unless otherwise justified. The structure and content of the final report should comply with TZA-11.
In addition, per TZA-5, the PI is required to submit a final report to the NatHREC once the last participant has completed all visits and all adverse experiences have been brought to appropriate resolution. Final reports must be submitted to the NatHREC on a Close-out Form (Form 08 in TZA-5) and processed as an expedited review. The Secretariat will review the Close-out Form. The expedited reviewer will request additional information from the researcher, as needed. Written documentation acknowledging the closeout will be provided to the investigator and a copy retained in the proposal file. Further, the G-EthicsHR-TZA requires researchers to submit a final report to the institutional EC containing a summary of the study's key findings, recommendations, and conclusions.
The G-ResearchClearance requires the researcher to submit a soft and hardcopy of the final report to COSTECH. The report should be accompanied with any relevant publications, electronic raw data, and proof of dissemination if applicable. The final report should include:
- COSTECH registration reference number
- Title of study
- Summary of report in English and Swahili
- Brief background and objective of the study
- Methodology, including study sites
- Key findings
- Constraints or problems encountered
- Conclusions and recommendations
As defined in the SA-GCPs, a sponsor is the person or organization responsible for the initiation, management, or financing of a clinical trial. A sponsor can be a pharmaceutical company, the principal investigator (PI), a funding body, or an individual or organization designated by the funding body or academic institution. An applicant can be an individual, company, institution, or organization that acts on behalf of the sponsor to initiate and manage the trial as its local representative. In the case of an international sponsor, a local applicant designated by the sponsor is responsible for initiation and management of the trial in the local context.
Per the SA-GCPs, a sponsor may transfer any or all trial-related duties and functions to a contract research organization (CRO). However, the sponsor is always ultimately responsible for the study data quality and integrity. Further, per the G-Monitor, the sponsor is solely responsible for adequate oversight of clinical trial conduct, including the justification for and selection of monitoring methods. Any trial-related responsibilities transferred to and assumed by a CRO should be specified in writing. The sponsor retains those responsibilities not specifically transferred to and assumed by a CRO.
Per the CT-Regs and the G-AppConductCT, a sponsor is defined as an individual, company, institution, or organization which takes responsibility for the initiation, management, and/or financing of a clinical trial. The Tanzanian government also permits a sponsor to authorize a contract research organization (CRO) to perform one (1) or more of a sponsor’s trial-related duties and functions.
As required in the G-EthicsHR-TZA, the sponsor is responsible for providing all the necessary financial support for the initiation and completion of the research study. Additional sponsor responsibilities include developing the final study report; providing forms for safety monitoring and reporting; securing compensation or indemnity in the event of research-related injuries, disability, or death; and managing matters related to the investigational new drug.
The G-EthicsHR-TZA states that research may be externally sponsored, meaning that it is sponsored, financed, and sometimes wholly or partly carried out by an external organization with the collaboration or agreement of the appropriate authorities of the host community.
Overview
As set forth in the SA-GCPs, the sponsor is responsible for using qualified individuals (e.g., biostatisticians, clinical pharmacologists, and physicians), as appropriate, throughout all stages of the trial process. Sponsors should select investigator(s) who are qualified by training and experience and have adequate resources to conduct the proposed clinical trial.
Per the SA-GCPs, all parties involved in the conduct of a trial should be familiar with the guidance in the International Council for Harmonisation's Guideline for Good Clinical Practice E6(R2) (ZAF-27) and other international guidelines.
Capacity Building & Training
As described in the G-Monitor, the sponsor should consider previous experience with the investigator or site, workload of the investigator, and resource availability at the study site during investigator and site selection. Per the G-Capacity, clinical trial applications should include evidence and activity plans to build capacity at each study site as well as enhancing research activities and skills of professionals from historically disadvantaged groups. Mandatory training in Good Clinical Practice (GCP) forms a part of capacity building. To support transformation and capacity building, the South African Health Products Regulatory Authority (SAHPRA) states that the sponsor must have a policy on “Capacity Building and Transformation in Clinical Research in SA” in place, and preferentially select sites that are compliant. See G-Capacity, for detailed information on actions that will comply with this requirement.
The G-EthicsHR-ZAF states that researchers must be suitably qualified and technically competent (trained and supervised, in the case of student researchers) to carry out the proposed research. The principal investigator (PI) has primary responsibility to ensure the safety and wellbeing of participants, the scientific integrity of the protocol, research data management, and responsible implementation of that protocol. Competence is demonstrated mainly by academic qualifications, credentials, and scientific and technical competence, as evidenced in previous publications or testimonials. Competence includes research competence, which is assessed in terms of education, knowledge, certification, and experience. In addition, researchers must produce evidence of appropriate research ethics training within the previous three (3) years.
The SA-GCPs prescribes mandatory GCP training with evidence of current (i.e., within three (3) years) GCP training and general research ethics training. To meet the required GCP training, the GCP-Trning indicates that virtual methods are acceptable (Zoom, Teams, etc.) for both basic and refresher training. Virtual training must be done properly, which includes monitoring interactive and active engagement of participants, and using a full-time facilitator (qualified to conduct training) available for the entire duration including questions and answers. To ensure inclusivity and fairness, consideration should be given to those who are unable to attend virtual training, especially in remote areas where internet accessibility remains a challenge. A hybrid model could be considered in this case. The duration of basic GCP training should be in alignment with the prescribed outcomes or unit standards (approximately two (2) days). The training content should be accredited by the Health Professions Council of South Africa (HPCSA).
Management of Investigators
According to the SA-GCPs, the sponsor must also define and allocate all study related duties and responsibilities to the investigator prior to initiating the study.
In addition, per ZAF-21, to add or change investigators and/or additional sites to an approved clinical trial, the sponsor must submit a signed application to SAHPRA. See ZAF-21 for details.
Per the G-CTInvestigators, SAHPRA will recognize and approve categories of investigators for trial leadership. The PI must be a South Africa-based scientist, who has sole or joint responsibility for the design, conduct, and delegation of trial responsibilities, analysis, and reporting. The PI is accountable to the sponsor and regulatory authorities. The PI can designate and supervise sub-principal investigator(s) (Sub-PI) of which at least one (1) must be a clinician and registered with the appropriate statutory entity to provide clinical oversight within their scope of practice. Further, the SAHPRA recognizes a category of co-principal investigator (co-PI), which allows for a team consisting of two (2) co-PIs to lead a study at a site. At least one (1) of the co-PIs must be a clinician registered with the appropriate statutory body and qualified to provide clinical oversight within their scope of practice. For multi-center studies, there must be a national PI appointed, who may or may not be a site PI. The national PI must have appropriate experience and expertise in that field and must be responsible for the application to the SAHPRA to conduct the study. The national PI must meet all other requirements to be a PI and sign a declaration accepting the responsibility as national PI and sign off on the clinical trial application. For more information on PI requirements, roles, and responsibilities, see the G-CTInvestigators.
Foreign Sponsor Responsibilities
As required in the SA-GCPs, if South Africa is selected as a clinical trial site but the country of origin or other high-income countries are not, the sponsor must explain the reason(s) why and provide a clear ethical justification. Further, multi-national trials should ensure that a reasonable proportion of project team members are South African researchers, including scientists and health care professionals and those from previously disadvantaged backgrounds.
Per the G-EthicsHR-ZAF, all international collaborative health research conducted in South Africa must undergo ethics review and approval by a South African registered EC and comply with the SA-GCPs. In addition, if international collaborators are affiliated with a foreign research institution or university, they must provide evidence of ethics review and approval from their home institution. International researchers are expected to demonstrate sensitivity to and understanding of the local socio-economic and political conditions of the research context, as these may indicate vulnerabilities of potential participants. It is advisable to create appropriate memoranda of understanding (MOUs) and agreements to establish the expectations, roles, and contributions of the various parties, as well as the limitations of the collaborative relationship. An agreement should exist between the host research institution and the collaborating institution(s) regarding all aspects of the research, including management of the research itself; research data management that includes the fate of the data and samples after completion of the study; financial arrangements; approach to research output publications; infrastructure development; allocation of intellectual property rights; and dispute resolution mechanisms. Selection of study participants is expected to be based on distributive justice and fairness. Risk/benefit assessments must be properly conducted to ensure that foreseeable risks of harm are mitigated and that anticipated benefits of participation are distributed fairly.
Data and Safety Monitoring Board
Per the SA-GCPs, the sponsor may establish an independent Data Safety Monitoring Board (DSMB) to assess the progress of a clinical trial, including safety data and critical efficacy endpoints at intervals, and to recommend to the sponsor whether to continue, modify, or stop a trial. The DSMB must have written standard operating procedures and must maintain written records of all its meetings.
Multicenter Studies
Per the SA-GCPs, if the trial is a multicenter and/or multi-country trial, any differences in trial designs between the South African and other sites must be clearly documented and explained in the trial protocol and/or related documents. In addition, international research groups must comply with South African regulatory requirements, and researchers must adapt the trial design and informed consent procedures to take into account local conditions and characteristics.
The G-EthicsHR-ZAF states that for international multi-site research, at least one (1) PI or co-PI must be physically in South Africa.
Overview
The Tanzanian government complies with the requirements delineated in the G-AppConductCT and the International Council for Harmonisation's Guideline for Good Clinical Practice E6(R2) (TZA-13) for conducting clinical trials. As set forth in TZA-13, the sponsor is responsible for selecting the investigator(s) and the institution(s) for the clinical trial, and for ensuring that the investigator(s) are qualified by training and experience. Additionally, the sponsor must define and allocate all study related duties and responsibilities to the relevant parties participating in the study. As delineated in TZA-13 and the G-AppConductCT, prior to entering into an agreement with the investigator(s) and the institution(s) to conduct a study, the sponsor should provide the investigator(s) with the protocol and an investigator’s brochure. Furthermore, the sponsor must sign an agreement or contract with the participating institution(s).
The G-AppConductCT delineates that the principal investigator (PI) must have the following minimum qualifications and experience:
- University degree in medicine, pharmacy, pharmacology, toxicology, or biochemistry and related fields
- Practical experience within the relevant professional area
- Previous experience as a co-investigator in at least two (2) trials in the relevant professional area
- Must be responsible for the conduct of the clinical trial at a clinical trial site
- Tanzanian resident
- In good standing with a professional organization
- For multicenter studies where the PI is not a resident of Tanzania, the appointed national PI must be a resident and should assume full responsibilities for all local clinical trial sites
- Ensure that sufficient time is available to conduct and complete the trial, and that other commitments or trials do not divert essential subjects, resources, or facilities away from the trial in hand
- The maximum number of clinical trials that a PI is allowed to supervise at the same time is five (5)
All investigators in a clinical trial, as well as the trial monitor, must have had formal training in Good Clinical Practices (GCPs) within the last three (3) years. Evidence of attending the GCP course should be submitted.
Per the G-AppConductCT, clinical trials must be carried out under conditions that ensure adequate safety for the participants. The site selected should be appropriate to the stage of development of the product and the potential risks involved. The trial site must have adequate facilities, including laboratories, equipment, and sufficient medical, paramedical, and clerical staff to support the trial and to deal with all reasonably foreseeable emergencies. All laboratory assays must be validated, and principles of Good Laboratory Practice (GLP) should be observed.
Per G-EthicsHR-TZA, institutions hosting research are overall accountable for research projects within their institutions. The institution must work closely with the investigators and monitor implementation of the research activities. Specifically, the host institution must ensure that they have qualified and competent investigators to carry out the research studies at the institution; facilitate the smooth implementation of research studies conducted at the institution; and take appropriate disciplinary action against investigators for non-compliance.
Foreign Sponsor Responsibilities
The G-EthicsHR-TZA states that research may be externally sponsored. The ethical standards should not be less stringent than they would be for research carried out in the country of the sponsoring organization. Local ethics committees (ECs) are fully empowered to disapprove a study they believe is unethical.
The G-ResearchClearance requires all foreign researchers to identify and affiliate to a local institution that has the appropriate capacity in the relevant type of research and obtain a local collaborator. Minimum qualifications of the local collaborator should be a person with a master’s degree and an expert in the relevant field of study. There should be a memorandum of agreement between the local institution/collaborator and the foreign researcher that includes methods for sharing data, material transfer agreements, access benefit sharing agreements, managing intellectual property, and dissemination of research results.
Data and Safety Monitoring Board
Per the G-EthicsHR-TZA, all Phase I, II, and III clinical trials, including drug efficacy trials, conducted in Tanzania must have a safety monitoring plan and Data and Safety Monitoring Board (DSMB) or a Data Monitoring Committee (DMC). Other interventional studies, such as community trials, may be required to set up DSMBs on a case-by-case basis. The National Health Research Ethics Committee (NatHREC) must ensure the establishment of a DSMB in all clinical trials to periodically assess the progress of implementation of safety data and the efficacy endpoints and to recommend to the sponsor whether to continue, modify, or terminate a trial. See the G-EthicsHR-TZA for details on the DSMB composition, qualifications, affiliation, terms of reference, and reporting.
As delineated in TZA-5, NatHREC considers DSMBs to be relevant in the following kind of studies:
- Controlled studies with mortality and/or severe morbidity as a primary or secondary endpoint
- Randomized controlled studies focused on evaluating the clinical efficacy and safety of a new intervention
- Early studies of a high-risk intervention
- Studies in the early phases of a novel intervention with very limited information on clinical safety
- Studies where the design or expected data accrual is complex, particularly studies with a long duration
- Studies carried out in emergency situations
The CT-Regs states that the DSMB requirement may depend on trial design and scientific background, risk and benefit assessment, or any other reasons determined by the NatHREC.
TZA-5 states that for clinical trials conducted only in Tanzania, the DSMB must include representation from Tanzania. For multi-country clinical trials, the DSMB must include regional representation, and a Tanzanian must be among the members. Where necessary, NatHREC may request that the sponsor submit the most recent report from the DSMB. In contrast, per TZA-1, for clinical trials that require a DSMB, the PI must submit a list of DSMB members, including at least one (1) Tanzanian, to the National Institute for Medical Research (NIMR). Additionally, the CT-Regs requires the following information:
- Trial objectives and terms of reference
- Member composition, qualifications, specific roles, and relationship to the investigators and study
- How meetings will be organized
The G-AppConductCT also specifies that a DSMB/DMC is required in situations where safety concerns may be unusually high. A DMC is recommended for any controlled trial of any size that will compare rates of mortality or major morbidity. It also indicates that a DSMB or DMC must be considered in the following situations:
- The study endpoint is such that a highly favorable or unfavorable result, or even a finding of futility, at an interim analysis might ethically require termination of the study before its planned completion
- There are a priori reasons for a particular safety concern (e.g., if the procedure for administering the treatment is particularly invasive)
- There is prior information suggesting the possibility of serious toxicity with the study treatment
- The study is being performed in a potentially fragile population such as children, pregnant women, the very elderly, other vulnerable populations, or those who are terminally ill or of diminished mental capacity
- The study is being performed in a population at elevated risk of death or other serious outcomes, even when the study objective addresses a lesser endpoint
- The study is large, of long duration, and multi-center
Additional details on the procedures and composition of the DSMB or DMC are provided in the G-AppConductCT and Part VIII of the CT-Regs. In addition, per the G-ReptSafetyData, the sponsor must also ensure that the DSMB’s interim safety data analyses are submitted to the Tanzania Medicines and Medical Devices Authority (TMDA).
Multicenter Studies
Per the G-EthicsHR-TZA, for multicenter studies, the study must be conducted in a methodologically identical way at each center. See the Scope of Review section for more details on multicenter studies.
As delineated in TZA-13, in the event of a multicenter clinical trial, the sponsor must ensure that:
- All investigators conduct the trial in strict compliance with the protocol agreed to by the sponsor, and, if required, by the TMDA, and given ethics committee (EC) approval
- The case report forms (CRFs) are designed to capture the required data at all multicenter trial sites
- Investigator responsibilities are documented prior to the start of the trial
- All investigators are given instructions on following the protocol, complying with a uniform set of standards to assess clinical and laboratory findings, and completing the CRFs
- Communication between investigators is facilitated
The CT-Regs and the G-AppConductCT also state that in the case of multicenter studies where the PI is foreign, the appointed national PI must be a resident and assume full responsibilities for all local clinical trial sites.
Insurance
As set forth in the G-Insurance and the SA-GCPs, all clinical trial sponsors and investigators must obtain adequate insurance and indemnity to cover any liability claims during the conduct of a clinical trial, in accordance with the responsibilities described in the SA-GCPs. As delineated in the SA-GCPs and G-Insurance, a sponsor must follow the principles set forth in the Association of the British Pharmaceutical Industry’s (ABPI) guidelines (ZAF-26 and ZAF-25) to comply with South Africa’s clinical trial insurance requirements. Per the SA-GCPs, research participants should not bear any financial cost to rectify harms that occur as a result of trial participation. The insurer pays the medical costs of necessary treatment to restore the previous position of the participant, if possible, when bodily or other injury is attributable to trial participation. Only bodily injuries of an enduring and disabling character (including exacerbation of an existing condition) and/or death are covered by the insurance. Temporary pain or discomfort or less serious or curable complaints are generally not regarded as trial-related, bodily injury. In the case of an in-utero injury due to the mother’s participation, payment for medical expenses proceeds as though the unborn child is a research participant. For additional details on limitations on liability, dispute resolution, weighting of risk factors, and insurance settlements, see the SA-GCPs. In addition, see the G-EthicsHR-ZAF, which reaffirms these requirements and provides legal analysis of insurance and legal claims.
Per the G-Insurance, the application to conduct a clinical trial must include evidence of comprehensive no fault insurance for serious injury and harm and/or death. In addition, the sponsor must provide indemnification for all investigators and trial sites involved in their clinical studies on compliance with the protocol requirements. In cases where the investigators/site staff were negligent and/or did not comply with the protocol requirements, personal malpractice insurance would apply.
As delineated in the G-Insurance and ZAF-23, an insurance certificate and indemnity must be included in the clinical trial application submitted to the South African Health Products Regulatory Authority (SAHPRA). Per the G-Insurance, the sponsor must include details of the insurance, including the following:
- Name and local address of the insurance company, including contact name and telephone number
- Title and protocol number of the clinical trial
- Date of commencement and termination of coverage
- Liability limit – per occurrence and total per occurrence and total for the study. Note that the limit should be adequate enough to cover extended stay in an intensive care unit or hospital
- Date of issuance of the insurance policy and expiry thereof
- Original or electronic signature of the insurer
- Special conditions if any. It is unacceptable to have special conditions which may invalidate or abate the clinical trial cover
- Any additional coverage
- Declaration of compliance with the SA-GCPs and ABPI guidelines on the certificate and in the patient information leaflet
- Where the insurance is not provided by a local company, a local insurance vendor must be identified with full details
- Insurance policy number
- The amount insured
Compensation
Injury or Death
As set forth in the G-Insurance, all clinical trial sponsors and investigators must have adequate insurance to cover any liability claims during the conduct of a clinical trial, in accordance with the responsibilities as described in the SA-GCPs. As delineated in the SA-GCPs and G-Insurance, a sponsor must follow the principles set forth in the ABPI guidelines (ZAF-26 and ZAF-25) to comply with South Africa’s participant compensation and treatment requirements for trial-related injuries. The guidelines state that the sponsor should furnish written assurance to the investigator that the sponsor will agree to pay compensation to participants and/or their legal heirs in the event of trial-related injuries or death. The investigator, in turn, communicates this information to the relevant ethics committee (EC).
The SA-GCPs, the G-Insurance, and ZAF-26 provide several compensation principles to guide sponsors in fulfilling their obligations (Note: Each of the items listed below will not necessarily be found in all sources, which provide overlapping and unique elements):
- Compensation should be paid when it can be demonstrated that a causal relationship exists between a participant’s injury and their participation in a trial
- Compensation should be paid when the injury results in permanent injury or disability to the participant
- When there is an adverse reaction to a medicinal product under trial, and injury is caused by a procedure adopted to deal with that adverse reaction
- The sponsor/applicant is under strict liability with respect to injuries caused by the investigational product (IP), and research participants should not bear any financial cost to rectify harms that occur as a result of trial participation
- The insurer should pay the medical costs of necessary treatment to restore the previous position of the participant, if possible
- In the case of an in-utero injury due to the mother’s participation, payment for medical expenses proceeds as though the unborn child is a research participant
- In principle, only bodily injuries of an enduring and disabling character (including exacerbation of an existing condition) and/or death are covered by the insurance; temporary pain or discomfort or less serious or curable complaints are generally not regarded as trial-related, bodily injury
- Where there is an adverse reaction to an IP and the injury is caused by a procedure adopted to deal with that adverse reaction, compensation should be paid for such injury as if it were caused directly by the IP
- Payment for medical expenses is made without acknowledgement of any legal liability and is thus to be understood to be an ex-gratia payment
- The provision of insurance cover and payment of medical expenses does not mean that an injured participant may not pursue legal action against the sponsor for loss or harm not covered by the insurance; however, an argument that pain and suffering, loss of income, and other possible claims should be paid for by the sponsor’s insurer is not sound in South African law and will not succeed
- The likelihood of an adverse reaction, or the fact that the participant has freely consented (whether in writing or otherwise) to participate in the trial should not exclude the participant from being eligible for compensation
According to the SA-GCPs and ZAF-26, the amount of compensation to be paid to the participant should be appropriate to the nature, severity, and persistence of the injury. The compensation should also be generally consistent with the amount of damages commonly awarded for similar injuries. The amount paid in compensation should be abated, or in certain circumstances excluded, in light of the following factors (which will depend on the risk level the participant can reasonably be expected to accept):
- The seriousness of the disease being treated
- The degree of probability that adverse reactions will occur and any warning given
- The risks and benefits of the established treatments relative to those known or suspected of the trial medicines
ZAF-26 provides that in any case where the sponsor agrees to pay the participant, but the two (2) parties differ on what is the appropriate level of compensation, it is recommended that the sponsor agree to seek, at the sponsor’s own cost, the opinion of a mutually acceptable independent expert. This opinion should then be made available to the participant(s), and the expert’s opinion should be given substantial weight by the sponsor in reaching a decision on the payment amount.
Additionally, any participant claims pursuant to ZAF-26 should be made to the sponsor, preferably via the investigator. The participant should include details on the nature and background of the claim, which the sponsor should review expeditiously. The review process may be delayed if the participant requests an authority to examine any medical records relevant to the claim.
Trial Participation
As specified in the G-TIECompensation and the SA-GCPs, the sponsor or the designated representative is responsible for providing compensation to research participants. The SA-GCPs state that before the clinical phase of the trial commences, the EC must approve the documentation on participant compensation. Per the G-EthicsHR-ZAF, the SA-GCPs, and the G-TIECompensation, compensation should be based on time, inconvenience, and expenses (TIE). In addition, the G-EthicsHR-ZAF and the SA-GCPs also address researcher requirements to budget for participant travel and other expenses. (See the G-EthicsHR-ZAF for detailed information).
The G-TIECompensation guides sponsors of approved clinical trials and proposes a model for minimum compensation that can be paid. It is not intended as an exclusive approach and the SAHPRA reserves the right to request any additional information. In addition, G-TIECompensation is not applicable to Phase I clinical trials, which pose a higher risk for participants and should be compensated on a different scale.
The G-EthicsHR-ZAF explains that inducements (also known as incentives) may be offered in justified circumstances (e.g., where recruitment is anticipated to be difficult) to encourage participation and to express appreciation by offering gifts over and above reimbursement of expenses and compensation for time and inconvenience. Inducements are not necessarily cash but may take other forms like data or airtime vouchers, food vouchers, etc. Importantly, an inducement should not unfairly influence an informed choice about whether to participate or undermine a potential participant’s ability to assess the risk of harm. This is especially important for Phase I and First in Humans clinical trials where the circumstances may involve healthy people being offered significant payments over and above those outlined in the TIE method. All inducements should be clearly explained and justified to the EC. If there are community members on the EC, their input may be constructive regarding appropriate inducements.
Post-Trial Access
The G-PostCTAccess guides sponsors on when to consider post-trial or continued access (PTA/CA) to the IP following the trial’s conclusion. Only those participants who derive benefit from the IP will be considered (this excludes participants on standard of care, placebo, and registered medicines). Where appropriate and available, the possibility of PTA/CA should be disclosed to and discussed with potential participants during the initial informed consent process or via a separate consent process. Where appropriate and/or available, details of potential PTA/CA should be included in the clinical trial application form, informed consent form, and patient information leaflet. Additional considerations include the following:
- PTA/CA is not applicable for Phase I and II studies. However, PTA/CA may be necessary for particular diseases (e.g., cancer or rare diseases).
- PTA/CA should be considered for Phase III studies when there is no registered and marketed standard of care in South Africa, provided that data from interim or final analyses shows that access is clinically justifiable.
- PTA/CA is not applicable to Phase IV studies
- A minimum of four (4) years after completion of the study is recommended as the acceptable time period to provide PTA/CA to the participants, unless there are compelling reasons for determining otherwise.
- During the PTA/CA period, the sponsor must ensure monitoring and oversight of participants using the IP.
Insurance
As set forth in the CT-Regs, the G-AppConductCT, the G-CTInsurance-TZA, and TZA-5, the sponsor or the designated contract research organization (CRO) is responsible for providing insurance coverage for any unforeseen injury to research participants. Before a clinical trial begins, the sponsor should also provide insurance and indemnify the investigator and the institution against claims arising from malpractice or negligence, and provide a copy of a valid insurance certificate from a recognized insurer in the clinical trial application submission. Additionally, per the CT-Regs, the insurance policy should be obtained from an insurance company registered in Tanzania. The G-CTInsurance-TZA and the G-AppConductCT state that details and proof of insurance must be provided in the ethics review submission. Furthermore, per the CT-Regs, for investigator-initiated trials, proof of current malpractice insurance that covers clinical trials must be provided to the Tanzania Medicines and Medical Devices Authority (TMDA). (See the Submission Content section for additional submission requirements.) The G-EthicsHR-TZA requires that insurance issues are clearly described in all clinical trial protocols, and that sponsors and investigators comply with the G-CTInsurance-TZA.
As per the CT-Regs and the G-CTInsurance-TZA, the sponsor or the designated CRO must sign an indemnity agreement with the host institution and the investigator(s) to cover any risks related to a research participant being injured by an investigational product, or from any procedure deemed necessary by the protocol. The sponsor and the institution’s chief executive officer must sign the indemnity. See Appendix 1 of the G-CTInsurance-TZA for a sample agreement. Per the CT-Regs, the sponsor must also indemnify the investigator against claims arising from the trial, except for claims that arise from malpractice or negligence.
The G-CTInsurance-TZA states that the insurance policy must meet the following requirements:
- Cover the conduct of the relevant clinical trial in Tanzania
- Provide a policy registered by the Tanzania Insurance Regulatory Authority (TIRA)
- Contain insurance coverage for an amount sufficient to meet the indemnification requirements applicable to the ethics committee (EC)-specified level of risk
- Cover claims made by research participants during the trial as well as those made after the trial is completed
Compensation
Injury or Death
As specified in the G-CTInsurance-TZA and the G-EthicsHR-TZA, the sponsor or the designated CRO is responsible for providing compensation to research participants and/or their legal heirs in the event of trial-related injuries or death. The sponsor must also ensure that participants who suffer any trial-related injuries are provided with free medical treatment for such injuries. The G-EthicsHR-TZA states that research study participants must not be asked to waive the right to compensation and must retain the legal rights to seek monetary compensation for research-related injuries including settlements out of court, in accordance with applicable laws in Tanzania.
Per TZA-5, investigator(s) must ensure participants (or their dependents in case of participant death) are equitably compensated should they sustain unexpected serious injuries (physical, psychological, or social harm) that are judged to be related to the investigational product (IP) or study procedure. Participants must not be compensated if they sustain expected adverse events or those related to other licensed medicines appropriately prescribed during the trial.
As per the G-CTInsurance-TZA, the amount of compensation paid should be appropriate to the nature, severity, and persistence of the injury. Compensation should be abated, or in certain circumstances excluded, in light of the following factors (which will depend on the risk level the participant can reasonably be expected to accept):
- The seriousness of the disease being treated
- The degree of probability that adverse reactions will occur and any warning given
- The risks and benefits of the established treatments relative to those known or suspected of the trial medicines
Trial Participation
As per the CT-Regs and the G-AppConductCT, participants may also be compensated for travel and incidental expenses incurred while participating in the trial. Per the G-AppConductCT, the clinical trial application must indicate the compensation to be received by participants, including a breakdown of costs.
The G-EthicsHR-TZA indicates that research study participants may be reimbursed for lost earnings, travel costs, lunch, and other expenses incurred in taking part in a study; they may also receive free medical services. Research participants, particularly those who receive no direct benefit from the research, will be compensated for inconvenience and time spent. Compensation must not be so large as to induce potential participants to consent to participate in the research study against their better judgement (undue inducement). A local EC must approve reimbursement and compensation for research study participants. Incentives to research study participants for their participation in research studies must not be considered a research benefit, but a recruitment incentive, and should not present undue influence on potential research participants.
Post-Trial Access
Per the study protocol template in the G-AppConductCT and TZA-42, details on post-trial access to products must be provided in the study protocol.
Per the G-EthicsHR-TZA, where appropriate, the clinical trial protocol should include a provision for the involvement of the community in the research process including the post-research period. The community in this context may be geographical or the study population. Further, there should be optimization of collateral benefits to the research communities including access to the products of the research. If the investigational product is found to be beneficial, the investigator should assist to secure its provision, without charge, to participants in the research study following the conclusion of the study.
Quality Assurance/Quality Control
Per the SA-GCPs, the sponsor is responsible for implementing a quality management system to manage quality throughout the design, conduct, recording, evaluation, reporting, and archiving of clinical trials. This quality management system should adopt a risk-based approach for risk identification, evaluation, control, communication, and reporting. The sponsor should focus on trial activities that promote human participant protection and reliability of trial results, which include using qualified individuals, designating qualified medical personnel to respond to trial-related medical questions, and ensuring all aspects of the trial are operationally feasible and avoiding unnecessary complexity, procedures, and data collection. With respect to quality assurance (QA) and quality control (QC), the sponsor is responsible for implementing and maintaining QA and QC systems with written standard operating procedures (SOPs) to ensure that trials are conducted and data are generated, documented (recorded), and reported in compliance with the protocol, good clinical practice, and the applicable regulatory requirement(s).
Per the G-Monitor, the responsibility for adequate oversight of the conduct of a clinical trial, including the justification for and selection of monitoring methods, remains that of the sponsor solely.
Per the SA-GCPs, all parties involved in the conduct of a trial should be familiar with guidance in the International Council for Harmonisation's Guideline for Good Clinical Practice E6(R2) (ZAF-27) and other international guidelines. Additionally, the investigator must agree to conduct the trial in compliance with the SA-GCPs, ZAF-27, South African Health Products Regulatory Authority (SAHPRA) requirements, and the ethics committee (EC) approved protocol. In the event of an interpretation conflict between the SA-GCPs and an international guideline, the SA-GCPs take precedence.
Monitoring Requirements
In accordance with the SA-GCPs, the sponsor must conduct an independent audit to evaluate trial conduct and compliance with the protocol, procedures, good clinical practice, and the applicable regulatory requirements. The sponsor must appoint individuals who are independent of the clinical trials to conduct the audits and ensure that the auditors are qualified by training and experience to conduct audits properly. The sponsor's audit plan and procedures for a trial audit must be guided by the number of participants in the trial, the type and complexity of the trial, the level of risks to the trial participants, and any identified problem(s). Observations and findings of the auditors must be documented. The sponsor is responsible for obtaining agreement from all involved parties to ensure direct access to all trial related sites, source data/documents, and reports for monitoring and auditing purposes, and inspection by domestic and foreign regulatory authorities.
In addition, per the G-Monitor, the sponsor’s monitoring plan should include planned audits to ensure that monitoring activities are in accordance with the monitoring plan, applicable regulations, guidance, and the sponsor’s plans and policies.
As delineated in the G-EthicsHR-ZAF, researchers are expected to provide appropriate information to the EC to facilitate monitoring, including alerts and investigator brochures.
Premature Study Termination/Suspension
Per the SA-GCPs, if a trial is prematurely terminated or suspended for any reason, the investigator must promptly inform the trial participants and ensure appropriate therapy and follow-up for them. If the investigator, sponsor, institution, SAHPRA, or the EC terminate or suspend a trial, the investigator must promptly inform the other parties with a detailed written explanation for the termination or suspension. The sponsor is also responsible for ensuring that the South African National Clinical Trials Register (SANCTR) (ZAF-48) is updated as well.
The G-EthicsHR-ZAF reiterates that if a project is terminated or suspended before the anticipated date of completion, then the researchers must report this immediately to the EC.
Quality Assurance/Quality Control
As stated in the CT-Regs and the G-AppConductCT, the Tanzanian government complies with the International Council for Harmonisation's Guideline for Good Clinical Practice E6(R2) (TZA-13) requirement that the sponsor implement and maintain quality assurance (QA) and quality control (QC) systems with written standard operating procedures (SOPs) to ensure that trials are conducted and data are generated, recorded, and reported in compliance with the protocol. Per the G-EthicsHR-TZA, the investigator is responsible for documenting all steps in data management to allow a step-by-step retrospective assessment of the quality of the data and the performance of the research study.
Per G-EthicsHR-TZA, during the conduct of clinical trials, deviations from the original study might occur, such as changes in the sample size or analysis of the data as described in the protocol. Deviations must be reported to ethics committees (ECs). In the case of permanent deviations, researchers may write an amendment. The EC must decide whether a deviation is accidental or purposeful. Protocol violations are deviations from the original protocol that significantly affect the rights or interests of research participants and the scientific validity of the data. In the case of protocol violations, study participants must be informed and provisions made to protect their safety and welfare. ECs may halt the continuation of a previously approved protocol if they find protocol violations or other misconduct. Any serious or continuing non-compliance with ethical standards in the conduct of previously approved research projects must be reported to the sponsor and institutional or governmental authorities by the study’s principal investigator (PI) and the Data and Safety Monitoring Board (DSMB).
Per TZA-13, the sponsor should implement a system to manage quality throughout all stages of the trial process, focusing on trial activities essential to ensuring participant protection and the reliability of trial results. The quality management system should use a risk-based approach that includes:
- Identifying processes and data that are critical to ensure participant protection and the reliability of trial results during protocol development
- Identifying risks to critical trial processes and data
- Evaluating the identified risks, against existing risk controls
- Deciding which risks to reduce and/or which risks to accept
- Documenting quality management activities and communicating to those involved in or affected by these activities
- Periodically reviewing risk control measures to ascertain whether the implemented quality management activities are effective and relevant
- Describing the quality management approach implemented in the trial and summarize important deviations from the predefined quality tolerance limits and remedial actions taken in the clinical study report
The G-AppConductCT states that the sponsor should ensure that the protocol or other written agreement specifies that the investigator(s)/institution(s) will permit Tanzania Medicines and Medical Devices Authority (TMDA) inspection(s) and provide direct access to source data/documents. Further, TZA-13 indicates that the sponsor is responsible for obtaining agreement from all involved parties to ensure direct access to all trial related sites, source data/documents, reports for monitoring and auditing purposes, and inspection by domestic and foreign regulatory authorities. QC should be applied to each stage of data handling to ensure that all data are reliable and have been correctly processed.
As described in the G-AppConductCT, study design, statistical considerations, choice of control groups, reporting of data, and conduct of the trial should also comply with the International Council for Harmonisation’s Efficacy Guidelines (E3-E16), provided in TZA-24.
Monitoring Requirements
As part of its QA system, the G-AppConductCT and TZA-13 note that the sponsor should ensure the trial is monitored and audited. The purpose of the audit should be to evaluate trial conduct and compliance with the protocol, SOPs, TZA-13, and other applicable regulatory requirements. The sponsor should appoint auditors to review the clinical trial, ensure that the auditors are qualified by training and experience, and document their qualifications. The sponsor must also ensure that the audit is conducted in accordance with any custom SOPs, the auditor observations are documented, and data are available as needed for the TMDA. No specific timeframe is provided for the audit process. The sponsor should develop a systematic, prioritized, risk-based approach to monitoring clinical trials. The extent and nature of monitoring is flexible and permits varied approaches that improve effectiveness and efficiency. The sponsor may choose on-site monitoring, a combination of on-site and centralized monitoring, or where justified, centralized monitoring. The sponsor should document the rationale for the chosen monitoring strategy (e.g., in the monitoring plan).
The G-GCPInspections provides guidance on clinical trial inspections to ensure the trial is conducted in accordance with the study protocol, procedures, TZA-13, and regulatory requirements, and that the data are accurate and valid. Inspectees (i.e., sponsor, investigator site, and contract research organization) should follow the G-GCPInspections requirements to ensure consistent conduct of trial inspections, including uniform reporting.
Per Pub-Rpts, to promote transparency of clinical trial oversight in the country, the TMDA will publish to its website clinical trial public assessment reports (CTPAR) and clinical trial public inspection reports (CTPIR) of all approved and ongoing clinical trials on an annual basis. The publication will only be undertaken after obtaining the consent of the respective PIs and sponsors. The PIs and sponsors are required to provide their consent within 14 days from the TMDA’s notification letter. Failure to respond is assumed to mean that the PIs and sponsors have consented to the publication of the CTPAR and CTPIR. For further clarification on this notice, contact TMDA at clinicaltrials@tmda.go.tz or info@tmda.go.tz.
Premature Study Termination/Suspension
The CT-Regs and the G-AppConductCT state that if a trial is prematurely terminated or suspended, the PI or the sponsor must inform the TMDA no later than 15 days after the date of the termination, and explain the reason(s) for the termination and its impact on the proposed or ongoing clinical trials. The sponsor or PI must also inform all co-investigators of the termination, the reasons for the termination, and advise them in writing of potential health risks to research participants. For each discontinued clinical trial site, the sponsor must stop the use or importation of the investigational product (IP) from the date of the trial’s discontinuation and take all reasonable measures to ensure the recovery of all unused quantities of the IP.
The G-EthicsHR-TZA also indicates that in the event of early termination of the research study, the investigator must inform, in writing, the appropriate EC, the National Institute for Medical Research (NIMR), the TMDA, and the research sponsor of the early termination and the underlying reason for such termination. Per TZA-5, the National Health Research Ethics Committee (NatHREC) should be notified if the investigator chooses to suspend the study. To resume a suspended study regardless of who initiated the suspension, the PI must submit a request to the Medical Research Coordination Committee (MRCC) with a report on the progress of addressing corrective actions. Research studies may be terminated based on the recommendation of the NatHREC, zonal or institutional ECs, DSMB, study sponsor, PI, or regulatory authority. In addition, a research study can be terminated due to an arising conflict of interest among investigators or financial misuse, which negatively affects implementation of the research project.
According to TZA-13, if it is discovered that noncompliance significantly affects or has the potential to significantly affect participant protection or reliability of trial results, the sponsor should perform a root cause analysis and implement appropriate corrective and preventive actions. Further, the EC should also be informed promptly and provided the reason(s) for the termination or suspension by the sponsor.
Electronic Data Processing System
Per the SA-GCPs, the sponsor must ensure that the electronic data processing system conforms to the specific documented requirements for completeness, accuracy, reliability, and consistency of intended performance, and that standard operating procedures for using these systems are maintained. In addition, the sponsor must:
- Ensure that the systems are designed to document data changes without deleting previously entered data (i.e., maintain an audit trail)
- Maintain a security system that prevents unauthorized access to the data
- Maintain a register of persons authorized to make data changes
- Maintain adequate data backup
- Ensure that blinding, if any, is maintained during data entry and processing
- Ensure the integrity and confidentiality of data, including any that describe the context, content, and structure of the data – especially when making changes to computerized systems
- If data are transformed during processing, it must be possible to compare the original data and observations with the processed data
- Use an unambiguous participant identification code that allows identification of all data reported for each participant
- Report any transfer of ownership of the data to the South African Health Products Regulatory Authority (SAHPRA)
See the G-EthicsHR-ZAF for detailed ethical, legal, and security considerations for database storage and access.
Per the G-Monitor, when developing a study’s monitoring plan, the sponsor should consider how it uses electronic data capture (EDC) systems. EDC systems that are capable of assessing quality metrics in real time will help identify high-risk sites that need more intensive monitoring.
Records Management
As set forth in the SA-GCPs, the sponsor should inform the investigator(s) in writing of the need for record retention, and should notify these parties in writing when the trial related records are no longer needed. The sponsor, or other data owners, must retain all the sponsor-specific essential documents pertaining to the trial for not less than 10 years or until at least two (2) years have elapsed since the formal discontinuation of clinical development of the investigational product (IP).
Electronic Data Processing System
As stated in the CT-Regs and the G-AppConductCT, the Tanzanian government complies with the International Council for Harmonisation's Guideline for Good Clinical Practice E6(R2) (TZA-13). As per TZA-13, when using electronic trial data processing systems, the sponsor must ensure that the electronic data processing system conforms to the sponsor’s established requirements for completeness, accuracy, reliability, and consistency of intended performance. Per TZA-13, the sponsor should base their approach to validate such systems on a risk assessment that takes into consideration the intended use and the potential of the system to affect participant protection and reliability of trial results. In addition, the sponsor should maintain standard operating procedures (SOPs) for the systems that cover system setup, installation, and use. The responsibilities of the sponsor, investigator, and other parties should be clear, and the system users should be provided with training. Refer to TZA-13 for additional information.
Records Management
The CT-Regs states that the investigator and the sponsor must retain all trial-related records, documents, and information at the trial site for a period not less than 20 years following the trial’s completion. Further, documentation should be retained for at least two (2) years after the last approval of a marketing application. The sponsor should inform the investigator(s) and the institution(s) in writing when trial-related records are no longer needed. See the CT-Regs for detailed record retention requirements. As set forth in TZA-13, all sponsor-specific essential documents used in the trial should be retained for at least two (2) years after formal discontinuation of the trial.
In addition, TZA-13 states that the sponsor and investigator/institution should maintain a record of the location(s) of their respective essential documents including source documents. The storage system used during the trial and for archiving (irrespective of the type of media used) should allow for document identification, version history, search, and retrieval. The sponsor should ensure that the investigator has control of and continuous access to the data reported to the sponsor. The investigator/institution should have control of all essential documents and records generated by the investigator/institution before, during, and after the trial.
Responsible Parties
For the purposes of data protection requirements, the POPIA provides that the “responsible party” is a public or private body or any other person that, alone or in conjunction with others, determines the purpose of and means for processing personal information.
Data Protection
Per the POPIA, participants have the right to privacy, which includes a right to protection against the unlawful collection, retention, dissemination, and use of personal information by public and private bodies. This right to privacy is subject to justifiable limitations that are aimed at protecting other rights and interests (e.g., the right of access to information). Additional information on the rights of data subjects is provided in the POPIA.
The POPIA states that the responsible party must protect the constitutional right to privacy by safeguarding personal information when it is processed. The law provides conditions under which personal information may be gathered and processed.
- Accountability – The responsible party must ensure that the conditions and all the measures in the POPIA are complied with at the time the purpose and means of processing is determined
- Processing limitation – Personal information may only be processed in a fair and lawful manner and only with the consent of the data subject
- Purpose specification – Personal information may only be processed for specific, explicitly defined, and legitimate reasons
- Further processing limitation – Personal information may not be processed for a secondary purpose unless that processing is compatible with the original purpose
- Information quality – The responsible party must take reasonable steps to ensure that the personal information collected is complete, accurate, not misleading, and updated where necessary
- Openness – The data subject whose information you are collecting must be aware that you are collecting such personal information and for what purpose the information will be used
- Security safeguards – Personal information must be kept secure against the risk of loss, unlawful access, interference, modification, unauthorized destruction and disclosure
- Data subject participation – Data subjects may request whether their personal information is held, as well as the correction and/or deletion of any personal information held about them
The G-EthicsHR-ZAF reaffirms that data protection measures should be aligned with the requirements of the POPIA, including the conditions for cross-border transfer and sharing of health data. To ensure data processing is lawful, fair, and transparent, researchers should submit a data management plan to the ethics committee (EC), which covers how data will be collected, stored, accessed, shared, and disposed of or retained. The data management plan should indicate how it complies with the POPIA, how data security will be maintained and the processes for possible data breaches. If data-sharing options include the use of open-access databases, the selected databases must meet the minimum legal, ethical, and security requirements. See the G-EthicsHR-ZAF for additional guidance and analysis. Also see the Specimen Import & Export section for details on sharing human biological material (HBM) and HBM data.
The POPIA establishes a duty requiring a public or private body to register its Information Officer with the Information Regulator (South Africa). Per the POPIA, the Information Officer is responsible for compliance with lawful processing of information and working with and responding to requests by the Regulator. Per the POPIA-Regs, the Information Officer has further responsibilities to:
- Develop, implement, monitor, and maintain a compliance framework
- Conduct a personal information impact assessment to ensure compliance with the conditions for the lawful processing of personal information
- Develop, monitor, and maintain a manual; and make it available upon request by any person, provide copies of the manual to any person upon request and payment of a fee to be determined by the Information Regulator from time to time
- Develop internal measures and systems to process requests for information or access
- Conduct internal awareness sessions on protection of personal information requirements
- Provide reasonable assistance free of charge to the data subject in objecting to processing of personal information (using Form 1 in the POPIA-Regs) and/or correcting or revising a record of personal information (using Form 2 in the POPIA-Regs)
The POPIA provides that records of personal information for research may be retained longer than is necessary for achieving the purpose for which the information was collected or processed if the responsible party has established appropriate safeguards against the records being used for any other purposes.
For additional guidance on processing personal data, including guidance on “special personal information” (e.g., health history) and personal information of children, see the Information Regulator website.
Consent for Processing Personal Data
Per the POPIA and the POPIA-Regs, personal information may only be processed if the data subject or legal representative/guardian consents to the processing. The responsible party bears the burden of proof for the consent. The data subject or legal representative/guardian may withdraw consent at any time if the lawfulness of the processing of personal information will not be affected.
As delineated in the G-EthicsHR-ZAF, consent to processing of personal information in terms of the POPIA requires a voluntary, specific, and informed expression of will, separate from the consent to participate in research. Special attention should be given to ensuring that computers and electronically stored data are protected from unauthorized access, inadvertent or accidental dissemination in the form of a ‘data dump’, etc. In general terms, a participant should know what personal information is being collected; why it is being collected; what will happen to it; how long it will be retained; whether it will identify the participant; whether it will be shared with others and why; whether it will be shared with third parties inside South Africa and why; and whether it will be sent outside South Africa and why. The participant should agree to these terms. Note that when processing some types of personal information, consent alone is insufficient as stipulated in the POPIA. Necessity must be evident too with special personal information, such as information about a person’s race or ethnic origin, a person’s health or sex life, a person’s inherited characteristics (genetic makeup), biometric information, or children’s personal information.
Consent for Processing Personal Data of Minors
Per the POPIA, there is a general prohibition on the processing of personal information of a minor. However, a responsible party may process personal information concerning a minor if the processing meets one (1) of the following conditions:
- It is carried out with the prior consent of a competent person
- It is necessary for the establishment, exercise, or defense of a right or obligation in law
- It is necessary to comply with an obligation of international public law
- It is for historical, statistical, or research purposes to the extent that the purpose serves a public interest and the processing is necessary for the purpose concerned; or it appears to be impossible or would involve a disproportionate effort to ask for consent and the processing does not adversely affect the individual privacy of the child to a disproportionate extent
- It is of personal information which has deliberately been made public by the minor with the consent of a competent person
As required in the G-EthicsHR-ZAF, when personal information about a minor (under 18 years) is to be processed, permission of a parent/legal guardian is required before data collection, even when permission is not required for the specific activity that gives rise to the information (e.g., donating blood). A minor aged 16 years or more may donate blood without parent/legal guardian permission, but the POPIA requires parent/legal guardian permission to process the information.
Responsible Parties
For the purposes of data protection requirements, PDP-Act delineates that the “data controller” (i.e., the natural/legal person or public body designated by law) is responsible for determining the purpose and means of processing personal data. The "data processor" processes personal data on behalf of the data controller. The “data protection officer” is an individual appointed by the data controller or data processor to ensure compliance with the PDP-Act and its regulations. Data controllers and processors must be registered with the Personal Data Protection Commission (PDPC). See the PDP-Reg-TZA for detailed procedures on registering with PDPC.
Data Protection
Per the PDP-Act, the data controller or data processor must protect personal data by ensuring that it is:
- Processed lawfully, fairly, and transparently
- Collected for explicit, specified, and legitimate purposes and not further processed in a manner incompatible with those purposes
- Adequate, relevant, and limited to what is necessary in relation to the purposes for which it is processed
- Accurate and where necessary, kept up to date, with every reasonable step taken to ensure that any inaccurate personal data is erased or rectified without delay
- Stored in a form which permits identification of data subjects for no longer than is necessary for the purposes for which the personal data is processed
- Processed in accordance with the rights of a data subject
- Processed in a manner that ensures appropriate security of the personal data, including protection against unauthorized or unlawful processing and against any loss, destruction, or damage
- Not transferred abroad contrary to the provisions of the PDP-Act
Regarding transborder data flow, the PDP-Act prohibits the transfer of personal data outside of Tanzania except under the following circumstances:
- If the data is transferred to a country that also has a data protection law enacted
- If the country does not have a data protection law, data may only be transferred outside of Tanzania based on several factors, including the recipient state's federal legal frameworks, security and privacy principles, the type of information being shared, the data transfer mechanisms in place, the specific reason for the transfer, and the proposed length of data processing (See the PDP-Act for more details)
See the PDP-Reg-TZA for detailed implementation requirements.
Consent for Processing Personal Data
Per the PDP-Act, before collecting data, a data controller must ensure that the data subject is aware of the purposes for which the personal data is collected; the fact that collection of the personal data is for authorized purposes; and any intended recipients of the personal data. However, the data controller is not required to inform the data subject if the personal data is publicly available, the data subject concerned authorizes the collection of the personal data from a third party, compliance is not reasonably practicable in the circumstances of the particular case, non-compliance is necessary per other written laws, or compliance would prejudice the lawful purpose of the collection.
As required in the PDP-Act, sensitive personal data must not be processed without obtaining prior written consent of the data subject, which may be withdrawn by the data subject at any time and without any explanation or charges. If the data subject is a minor, a person of unsound mind, or any other person unable to consent, such person’s consent must be obtained or sought from the legal representative(s)/guardian(s). Exceptions to this rule apply where the processing is necessary in these circumstances:
- Compliance with other written laws
- To protect the vital interests of the data subject or of another person, where the data subject is incapable of giving consent or is not represented by a legal representative
- Necessary for the institution, trial, or defense of legal claims
- Relates to personal data that has been made public by the data subject
- The purposes of scientific research and the PDPC has, by special guidelines, specified the circumstances under which such processing may be carried out
- For the purposes of medical reasons in the interest of the data subject and the sensitive personal data concerned is processed under the supervision of a health professional in accordance with the law
Further, the PDP-Act delineates that data collected may only be disclosed if the data subject has consented to such disclosure and if the disclosure is authorized or required by law, directly related to the purpose for which such data was collected, and/or would preserve health or reduce harm to another person or the society. Disclosure of information may also be permitted where the data subject is not identified for statistical or research purposes and where it is guaranteed that such data will not be published in a manner that will identify the data subject. Additionally, data collectors must establish a code of ethics for personal data protection during collection or processing of personal data, and they must maintain a proper security system.
Per the PDP-Reg-TZA, the rights of participants regarding their personal data are the autonomous right to control their personal data, the right to communicate and exercise their data rights, and the right to human intervention to minimize biases that automated processes may create. In addition, per the G-EthicsHR-TZA, researchers using online and digital tools must protect the individual’s right to privacy and confidentiality including whether they knew or were expected to know that records and data were being kept. If individuals have reasonable expectations of privacy and impermanence of their online activities, then researchers may need to take specific measures to inform the respondents and obtain their consent to use their data for research. Further, if studies use artificial intelligence, the participant’s “right to be forgotten” must be protected by enabling their ability to request that a search engine remove information about them.
Obtaining Consent
In all South African clinical trials, a freely given, written informed consent is required to be obtained from each participant in accordance with the principles set forth in the NHA, the Declaration of Helsinki (ZAF-44), the SA-GCPs, and the International Council for Harmonisation's Guideline for Good Clinical Practice E6(R2) (ZAF-27).
As per the SA-GCPs and the G-GPHlthCare, the informed consent form (ICF) and patient information sheet(s) are essential documents that must be reviewed and approved by a registered ethics committee (EC) based in South Africa and provided to the South African Health Products Regulatory Authority (SAHPRA) with the clinical trial application. (See the Required Elements section for details on what should be included in the form.) The principal investigator (PI), or a person designated by the PI, should provide research study information to the participant or legal representative/guardian. When drafting and presenting the ICF, special consideration must be taken with regard to the participant’s culture, traditional values, intelligence, and education. The informed consent document should be non-technical and understandable to the participant and in a participant’s preferred written language. The ICF content should be briefly and clearly presented, without coercion or unduly influencing a potential participant to enroll in the clinical trial.
The SA-GCPs directs that none of the oral or written information concerning the study, including the written ICF, should contain any language that causes the participant or legal representative/guardian to waive or appear to waive their legal rights, or that releases or appears to release the investigator(s), the institution, the sponsor, or the representatives from the sponsor’s liabilities for any negligence.
G-EthicsHR-ZAF explains that an important element of enabling an informed choice is the nature and quality of information made available to the potential participant, such as reading the information sheet and/or dialoguing with the participants, allowing for verbal consent, which is then recorded and transcribed or documented manually in the researchers’ notes. The process should permit sufficient time for consultation between the recruitment step and the time of deciding whether to participate. No person should be required to make an immediate decision. ECs should assess the proposed process for informed consent as well as the information that potential participants will be given and the measures to facilitate understanding. Considerations for assessment include whether:
- The informed consent setting is sufficiently private and appropriate to minimize the possibility of undue influence
- The person conducting the informed consent process is appropriately trained, independent, and bias-free
- The text is in plain language and appropriate to the participants’ level of understanding with translations, as needed
Re-Consent
The G-GPHlthCare-IC states that the participant must be informed of any relevant new findings over the course of the study, and be given the choice to continue to participate or withdraw from the study. Per the SA-GCPs, written informed consent documentation and other participant-related information should be revised when new information that may be relevant to a participant’s consent or willingness to continue to participate in the trial becomes available. Any revisions must be submitted for ethics review and approval before implementation. Communication of the new information to participants must be documented.
Per the G-EthicsHR-ZAF, the informed consent should be a trust-based process and relationship between the researcher and the participants, groups, and communities that extends over time. Consent must be negotiated and renegotiated as the research continues and develops.
Language Requirements
According to the SA-GCPs, the ICF should be provided in a participant’s preferred written language. The G-GPHlthCare states that the researchers should provide information to the participants in a language that the participant understands and in a manner that takes into account the participant’s level of literacy, understanding, values, and personal belief systems.
The G-EthicsHR-ZAF states that informed consent material must be translated into the language(s) best suited for the population and context of the study. If appropriate, the consent documents can be translated. However, merely translating documents is insufficient to ensure that consent is informed because illiteracy is prevalent in some contexts, language dialects vary substantially across regions, some words and terminology are not easily translated, translated written materials may not be helpful to some participants, and/or professional translators are not content experts so mistranslation may occur. Therefore, it may be more useful to train a research assistant/interpreter who can explain information about the study verbally to potential participants in their language of choice and answer any questions they may have about the study.
Regarding the plain language text, the G-EthicsHR-ZAF indicates that the text should be appropriate to the participants’ level of understanding, which means:
- Translated into the language(s) best suited for the population and context of the study
- Has content, language(s), and procedures that are simplified and modified to accommodate any written or verbal language differences or impairments with which the participant may present
- Free of jargon and unexplained acronyms
- Clear and explains technical terminology
Documenting Consent
As stated in the SA-GCPs and the G-GPHlthCare, the ICF should be signed by the participant and the PI, or the person designated by the PI. If the participant is incapable of giving an informed consent, the legal representative/guardian should sign the ICF. The original signed ICF and patient information sheet(s) should be retained by the investigator and a copy should be given to the participant. The SA-GCPs requires an additional copy of the signed ICF and a source document identifying the study and recording the participation dates should be placed in the participant’s medical records. According to the NHA, the SA-GCPs, the G-EthicsHR-ZAF, the G-GPHlthCare, and the G-GPHlthCare-IC, in all cases, written informed consent must be obtained. Where the participant is illiterate and/or the legal representative/guardian is illiterate, verbal consent should be obtained in the presence of and countersigned by a literate witness. The participant or legal representative/guardian, the PI or person designated by the PI, and if applicable, a literate witness must personally sign the ICF. Further, the SA-GCPs states that the participant should indicate willingness to participate by making a mark (either a cross or a fingerprint). The witness signs to affirm that the participant willingly consented to participate. The witness dates the mark and signature.
The G-EthicsHR-ZAF indicates that there may be circumstances where alternative forms of obtaining consent are allowed when it is not possible to have written consent. If it is ethically justifiable for the specific circumstances, then verbal consent may be approved. Usually, if verbal consent is permitted, a witness attests that the person did consent to participation after indicating understanding of the information provided. In addition, sometimes the nature of the research requires electronic data collection, or the potential participants may have an impairment that prevents a personal face-to-face consent process with written consent. Alternatives to face-to-face personal consent may not occur without sound justification approved by a registered EC. The justification for an alternate format of consent process must be evidenced by clear descriptions of why an alternative is justified in the circumstances and how the interests of the potential participant are properly protected.
Per the G-EthicsHR-ZAF, where electronic consent is proposed, the research protocol must describe in detail the method and process for obtaining consent. Electronic signatures are a functional equivalent of a paper-based signature with the same legal authority if it meets legal requirements including:
- A typed name at the end of an email
- A scanned image of a handwritten signature embedded into a document
- A digital signature
Further, the G-EthicsHR-ZAF states that in regards to telephonic (verbal) and electronic informed consent, EC reviewers of research protocols must insist on a proper decisive description of how informed consent will be regarded as authentic. The following electronic methods of obtaining informed consent are recommended:
- Telephonic recruitment for research that poses more than minimal risk of harm should be limited to screening for eligibility, followed by face-to-face informed consent, or virtual informed consent via an electronic platform
- Telephonic research surveys are possible for minimal risk studies, and verbal agreement to participate serves as informed consent
- For research that poses more than minimal risk of harm, different electronic platforms could be used for different purposes: a technology (e.g., email) to screen and obtain informed consent and another system to collect data
Waiver of Consent
Per the G-EthicsHR-ZAF, any decision by the EC to grant a waiver of participant or legal representative/guardian consent must be documented and must include the justification for the decision. A waiver of consent to conduct the research can be justified on two (2) grounds: if the waiver will not infringe upon any right of a participant, and obtaining consent is impracticable; or if the rights infringement is minimal and is outweighed by the expected social value of the research, and obtaining consent is impracticable. Any decision by the EC to grant a waiver of participant or legal representative/guardian consent must be documented and must include the justification for the decision. A waiver of consent is not automatic and requires a researcher to apply to the EC for approval to use someone's personal information or personal health information without obtaining consent from the individual. The application must explain why a waiver is requested and how one of the justification criteria above applies. The EC must assess the level of risk of harm associated with a waiver, which refers to the risk of harm flowing from researchers accessing identifiable private information and not to risk of harm concerning the whole research project. An alteration of requirements for informed consent (as opposed to a full waiver) is possible, e.g., when existence of a signed consent form might pose a risk of harm (breach of confidentiality) to the participant in studies involving illegal behavior. The alteration may take the form of permitting unsigned informed consent documentation.
Obtaining Consent
In all Tanzanian clinical trials, a freely given informed consent must be obtained from each participant in accordance with the requirements set forth in the CT-Regs, the G-AppConductCT, and the G-EthicsHR-TZA. As per the G-AppConductCT and the G-EthicsHR-TZA, the informed consent form (ICF) is viewed as an essential document that must be reviewed and approved by the national ethics committee (EC), the National Health Research Ethics Committee (NatHREC), and provided to the Tanzania Medicines and Medical Devices Authority (TMDA) for approval with the clinical trial application. (See the Required Elements section for details on what should be included in the form.)
The G-AppConductCT and the G-EthicsHR-TZA state that the investigator, or the designated representative, must provide detailed research study information to the participant or the legal representative/guardian. The G-AppConductCT, the G-EthicsHR-TZA, and TZA-5 also specify that the oral and written information concerning the trial, including the ICF, should be easy to understand and presented without coercion or unduly influencing a potential participant to enroll in the clinical trial. The participant and the legal representative/guardian, should also be given adequate time to consider whether to participate. The G-EthicsHR-TZA indicates that informed consent protects the individual’s freedom of choice and respects the individual’s autonomy. The consent process should be a flow of information exchange between the researcher and research participants during the whole research process. The information provided should be adequate, and clearly understood by the research participants. Seeking consent must be carried out under circumstances that provide the prospective research participant or the representative sufficient opportunity to consider whether to participate and minimize the possibility of coercion or undue influence. The information given to the research participant or the representative, whether it is conveyed orally, in writing, or another delivery mechanism, must be in a language and form understandable to the participant or the legal representative/guardian.
As per the G-AppConductCT and the G-EthicsHR-TZA, none of the oral and written information concerning the research study, including the written ICF, should contain any language that causes the participant or the legal representative/guardian to waive or to appear to waive their legal rights, or that releases or appears to release the investigator(s), the institution, the sponsor, or their representatives from their liabilities for any negligence.
Per the G-EthicsHR-TZA, for verbal consent, the procedures used to obtain consent must be described within the ethics application, and the verbal consent must still contain all of the elements required for informed consent.
Re-Consent
According to G-AppConductCT, any change in the ICF due to a protocol modification or an alteration in treatment modality, procedures, or site visits, should be approved by the NatHREC and the TMDA prior to implementing any changes. The participant or the legal representative/guardian should also be informed in a timely manner if new information becomes available that may be relevant to the participant’s willingness to continue participation in the trial. The communication of this information should be documented.
Per the G-EthicsHR-TZA, the investigator must ensure that there is continued adequacy of the informed consent process and renewal of informed consent if there are significant changes in the conditions or procedures of the research project or if new information becomes available that could affect the research participant’s willingness to continue in the research project.
Regarding secondary use of materials or data in databases, registries, and repositories, the G-EthicsHR-TZA states that in the absence of broad consent to future use of material or data, including images, for research purposes, the following is recommended:
- The nature of the previously obtained consent should be determined to ascertain whether subsequent usage was envisaged and whether it falls within the scope of the current protocol. If so, new consent is not required
- If the scope of the current protocol is different, then new consent may be required
- If samples are anonymous and the results of research would not place any individual, family, or community at social, psychological, legal, or economic risk of harm, then new consent is not required
- If the link to identifiers exists but is not provided to the research team and the results of research will not place any individual, family, or community at social, psychological, legal, or economic risk of harm, then new consent is not required. The person who holds the code or link should sign an explicit written agreement not to release the identifiers to the research team. This agreement should be submitted to the EC
- If the samples can be linked to identifiers, the EC must decide on a case-by-case basis whether expedited or full review is necessary
Language Requirements
As stated in the G-AppConductCT, the ICF content should be presented in both English and Kiswahili, and all information given to participants, both oral and written, must be in both English and Kiswahili.
Documenting Consent
The G-AppConductCT and the G-EthicsHR-TZA state that the participant or the legal representative/guardian, and the person who conducted the informed consent discussion must sign and date the ICF. Where the participant is illiterate and/or the legal representative/guardian is illiterate, verbal consent should be obtained in the presence of and countersigned by an impartial witness. Before participating in the study, the participant should receive a copy of the signed and dated ICF, and any other written information provided during the informed consent process. The G-AppConductCT states that the participant or the legal representative/guardian should also receive a copy of any updates to the signed and dated ICF, and copies of any amendments to the written information originally provided.
Per the G-EthicsHR-TZA, the study participant may imply consent by voluntary actions (e.g., express consent verbally or sign (written consent form)). A verbal or oral consent process is where the researcher and participant have a conversation to give information and obtain consent. Usually, oral consent is used when it is not possible to get written consent. The verbal consent may be deemed appropriate and applied under the following situations where:
- The study is deemed to be of minimal risk
- There are cultural or political concerns with signing contract-like documents
- The researcher and or participants could be put at risk by the existence of a paper record
- The study is conducted remotely via video conferencing software, telephone, etc.
- It may not be feasible in large information-taking settings (e.g., some focus group discussions (FGDs)); however, documentation of verbal consent for participants in FGDs must be written down to include the names of participants who consented verbally and those that did not
Waiver of Consent
Per the G-EthicsHR-TZA, for research that is no more than minimal risk, the EC may approve a request to waive some or all of the required elements of informed consent under specific circumstances. Waivers of informed consent are primarily requested for projects involving the secondary analysis of existing data. To waive or alter informed consent elements, the following conditions must be met:
- The study could not practicably be carried out without the waiver or alteration (whenever appropriate the study participants will be provided with additional pertinent information after participation)
- In situations where deception needs to be applied to achieve the objectives of the study
- The only record linking the study participant and the study would be the consent document and the principal risk to the research participant would be potential harm resulting from a breach of confidentiality
- The study participant presents in an emergency situation and informed consent cannot be reasonably obtained (See the Emergencies section for more information)
The G-EthicsHR-TZA states that if a waiver of written informed consent is granted by the EC, then each study participant should be asked whether they wish to have documentation that links them with the study; and the participant’s wishes must govern.
Based on the informed consent essential elements in the SA-GCPs, the G-EthicsHR-ZAF, the G-GPHlthCare, G-PostCTAccess, and the NHAParticipants, the informed consent form (ICF) should include the following statements or descriptions, as applicable (Note: Each of the items listed below will not necessarily be found in all sources, which provide overlapping and unique elements):

Compensation Disclosure
Regarding compensation, TZA-5 states that investigator(s) must ensure participants are aware of the compensation guidelines and that their rights regarding compensation are protected. Participants must not be asked to waive their rights to free treatment or compensation for research-related harms, nor must they be required to show negligence or lack of a reasonable degree of skill on the part of the researcher to claim free treatment or compensation. The informed consent process or form must not contain statements that would absolve a researcher from responsibility in the case of harm, or that would imply that participants waive their right to seek compensation.
See the Vulnerable Populations and Consent for Specimen sections for further information.
Overview
South Africa’s ethical standards promote respect for all human beings and safeguard the rights of research study participants. In accordance with the principles held forth in the Declaration of Helsinki (ZAF-44), the SA-GCPs, the G-EthicsHR-ZAF, the G-GPHlthCare, the G-GPHlthCare-IC, the NHAParticipants, and the International Council for Harmonisation’s Guideline for Good Clinical Practice E6(R2) (ZAF-27), a participant’s rights must be clearly addressed in the informed consent form (ICF) and during the informed consent process. Below are the basic rights for participants in clinical research studies. (See the Required Elements and Vulnerable Populations sections for additional information regarding requirements for participant rights.)
The Right to Participate, Abstain, or Withdraw
According to the NHA and the NHAParticipants, everyone has the right to participate in any decision affecting their health or treatment, including research. The participant or legal representative/guardian should be informed that participation is voluntary, that the participant may withdraw from the research study at any time, and that refusal to participate will not involve any penalty or loss of benefits to which the participant is otherwise entitled.
The Right to Information
According to the G-GPHlthCare-IC, a potential research study participant has the right to be fully informed on the nature and purpose of the research study, its anticipated duration, the sponsor and investigator(s), any potential benefits or risks, study procedures, any compensation for participation, injury and/or treatment, and any significant new information regarding the research study. (See the Required Elements section for a more detailed list.)
Per POAIA, a participant may seek access to their clinical trial records, pursuant to their constitutional right of access to any information held by the State or by another person.
The Right to Privacy and Confidentiality
Per the G-GPHlthCare-IC, participants have the right to privacy and confidentiality, and the ICF must provide a statement identifying this right. It is the responsibility of the investigator to safeguard the confidentiality of research data to protect the identity and records of research participants.
The Right of Inquiry/Appeal
Per the G-GPHlthCare-IC, the research participant or legal representative/guardian should be provided with contact information for the investigator(s), and the ethics committee to address clinical trial-related queries, in the event of any injury and/or to appeal against a violation of the participant’s rights. It is also required that the South African Health Products Regulatory Authority (SAHPRA) address and contact information be provided. (See the Required Elements section for more detailed information regarding participant rights.)
The Right to Safety and Welfare
The SA-GCPs and ZAF-44 clearly state that research participants have the right to safety and well-being, which must take precedence over the interest of science and society. The NHA and the NHAParticipants safeguard the rights of all South Africans including vulnerable populations.
Overview
As stated in the G-AppConductCT, the Tanzanian government complies with the ethical principles set forth in the International Council for Harmonisation’s Guideline for Good Clinical Practice E6(R2) (TZA-13) and the Declaration of Helsinki (TZA-30), which promote respect for all human beings and safeguard the rights of research participants. A participant’s rights must also be clearly addressed in the informed consent form (ICF) and during the informed consent process. (See the Required Elements and Vulnerable Populations sections for additional information regarding requirements for participant rights.)
The Right to Participate, Abstain, or Withdraw
As set forth in the G-AppConductCT and the G-EthicsHR-TZA, the participant or the legal representative/guardian should be informed that participation is voluntary, that the participant may withdraw from the research study at any time, and that refusal to participate will not involve any penalty or loss of benefits to which the participant is otherwise entitled.
The Right to Information
As delineated in the G-AppConductCT and the G-EthicsHR-TZA, a potential research participant or the legal representative/guardian has the right to be informed about the nature and purpose of the research study, its anticipated duration, study procedures, any potential benefits or risks, any compensation for participation or injury/treatment, and any significant new information regarding the research study. (See the Required Elements section for more detailed information regarding participant rights.) The G-EthicsHR-TZA states that information about the research study must be communicated in understandable and legally accepted language and format, and in a conducive environment, at all stages of the research.
The Right to Privacy and Confidentiality
As per the G-AppConductCT and the G-EthicsHR-TZA, all participants must be afforded the right to privacy and confidentiality, and the ICF must provide a statement that recognizes this right.
The Right of Inquiry/Appeal
The G-AppConductCT and the G-EthicsHR-TZA state that the research participant or the legal representative/guardian should be provided with contact information for the sponsor and the investigator(s) to address trial-related inquiries. (See the Required Elements section for more detailed information regarding participant rights.)
The Right to Safety and Welfare
As specified in the CT-Regs, the G-EthicsHR-TZA, and the G-AppConductCT, the Tanzanian government complies with the principles in TZA-13 that state a research participant’s right to safety and the protection of the participant’s health and welfare must take precedence over the interests of science and society.
The NHA and the G-EthicsHR-ZAF make provisions to protect the rights of a research participant during the informed consent process when the procedure is complicated by medical emergencies. As per the G-EthicsHR-ZAF, there are emergency situations that merit use of deferred consent (also called delayed consent). Usually, the circumstances entail a temporary loss of decision-making capacity and a reasonably held prognosis that the person will regain the capacity within a predictable period (e.g., an unconscious patient in the Emergency Unit who is predicted to regain consciousness within hours). Deferred consent should be used only where the likelihood of obtaining personal informed consent after the research has begun is likely. The ethics committee (EC) may approve use of deferred consent if the following conditions are met:
- The proposed research is based on valid scientific hypotheses that support a reasonable possibility of more benefit than that offered by standard care
- The individual has a temporary loss of decision-making capacity
- There is a reasonably held prognosis that they will regain the capacity within a predictable period
- Participation is not contrary to the medical interests of the patient
- When the individual regains capacity to make decisions, they must be informed that they have been enrolled in a research study (i.e., deferred consent must be obtained); if they object to having been enrolled in the study, this counts as a refusal to participate, and they should be asked whether their data already collected must be withdrawn
If death of the participant occurs before deferred consent can be obtained, it should not be assumed that continued use of the data and/or samples is ethical. The deceased’s wishes or those of their proxy or mandate holder should be ascertained.
Per the G-EthicsHR-ZAF, during disease outbreaks, potential participants must be assisted to understand the research proposed and the implications of enrollment, despite the situational duress and anxiety. The notion that informed consent is a process does not change because the research is being conducted in pandemic circumstances. Research during a public health emergency must adhere to standard research ethics principles including informed consent.
Per the G-CTAPHEmerg, the South African Health Products Regulatory Authority (SAHPRA) states that during a public health emergency, informed consent and the patient information sheet(s) remain essential documents that must be reviewed and approved by an EC and provided to the SAHPRA with the clinical trial application.
As per the G-AppConductCT, in an emergency, if the signed informed consent form (ICF) cannot be obtained from the research participant, the consent of the legal representative/guardian should be obtained. If prior consent from the participant or the legal representative/guardian cannot be obtained, participant enrollment should require measures described in the protocol and/or elsewhere. Tanzania Medicines and Medical Devices Authority (TMDA) approval should also be obtained in order to protect the participant’s rights, safety, and well-being and to ensure compliance with National Health Research Ethics Committee (NatHREC) and TMDA requirements. The participant or the legal representative/guardian should provide consent as soon as possible.
In addition, per the G-EthicsHR-TZA, an EC may approve a waiver of consent if the study participant presents in an emergency situation and informed consent cannot be reasonably obtained from the participant or the legal representative/guardian. During a public health emergency of national and international concern, some of the activities focusing on diseases or events threatening national and international health security are considered non-research and need immediate attention. Informed consent may not be required in non-research activities.
Overview
The NHA, the SA-GCPs, the G-EthicsHR-ZAF, the G-GPHlthCare, and the NHAParticipants require special considerations for vulnerable populations, and characterize them by limited education, limited economic resources, inadequate protection of human rights, discrimination due to health status, limited ability to provide informed consent, limited availability of health care and treatment options, or an inadequate understanding of scientific research. Vulnerable populations include children/minors, mentally and physically disabled, pregnant women, substance abusers, prisoners, armed forces, the homeless, the elderly, members of a group with a hierarchical structure, patients with incurable diseases, persons in nursing homes, unemployed or impoverished persons, patients in emergency situations, ethnic minority groups, nomads, refugees, and other vulnerable groups such as persons in dependent relationships. (Note: Each of the items listed above will not necessarily be found in all sources, which provide overlapping and unique elements).
The SA-GCPs state that ethics committees (ECs) must pay special attention to protecting participants from vulnerable populations. The ECs may impose additional measures such as imposing additional protective measures for the informed consent process or requiring increased monitoring and interim reporting on the participants’ welfare. As per the NHAParticipants, research with vulnerable participants must comply with the following requirements:
- Involve vulnerable persons only when non-vulnerable persons are not appropriate for inclusion
- Not systematically avoid inclusion of vulnerable participants because it is unfairly discriminatory, and would prevent this population from benefiting from relevant research
- Be responsive to health needs and priorities of vulnerable persons, and
- Provide special attention in the ethical review to ensure research-related risks are assessed and minimized, and appropriate consent procedures are followed
Per the G-EthicsHR-ZAF, where factors usually associated with vulnerability are integral to the research, the protocol should demonstrate how vulnerability will be managed. In cases where the researcher is known to the community and speaks the local language and/or is accepted as part of that community, this may be seen as a positive element for the research context. Special care should be exercised before undertaking research involving participants in such communities, and ECs should ensure that:
- Persons in these communities are not being involved in the research merely because they are expediently accessible, while the research is feasible to undertake in a less vulnerable community
- Research is relevant to the needs and priorities of the targeted community
- Research participants know they will take part in research and that the research will be carried out only with appropriate consent
See the Children/Minors; Pregnant Women, Fetuses & Neonates; Prisoners; and Mentally Impaired sections for additional information about these populations.
Persons in Dependent Relationships or Hierarchical Situations
As indicated in the SA-GCPs and the G-EthicsHR-ZAF, participants whose proposed involvement in research arises from dependent or hierarchical relationships need additional attention, and particular attention should be given to ensuring that their consent is both adequately informed and voluntary. In addition, per the NHAParticipants, research is appropriate when research-related risks of harm are minimized. These types of relationships include, but are not limited to, those who are in junior or subordinate positions in hierarchically structured groups, such as prisoners and prison authorities, older persons and their caregivers, and patients and healthcare professionals.
Persons Highly Dependent on Medical Care
Per G-EthicsHR-ZAF, individuals who are highly dependent on medical care deserve special attention when considering research participation. The gravity of their medical condition may require invasive measures that carry increased risk of harm. The quality of informed consent may be compromised by the effect the medical condition has on the participant’s decision-making or communication abilities. A patient may be reluctant to refuse consent for fear that this may compromise their medical treatment. Adequate provision must be made for informing patients and their relatives about the research to ensure that stress and other emotional factors do not impair their understanding. Their dependency on caregivers should not unfairly affect research participation decisions.
Persons with Physical Disabilities
As described in the G-EthicsHR-ZAF, recruitment strategies for research participation should be sensitive to the possibility that persons with visual, hearing, or mobility impairments may wish to volunteer, and, therefore, should ensure that there are no unintended barriers to such participation (e.g., the absence of ramps or a lift for wheelchair-bound potential participants). Research involving participants with physical disabilities should anticipate possible barriers and include measures to minimize them.
Elderly Persons
As per the G-GPHlthCare, research involving elderly persons requires consent to be provided by the participant’s legal representative/guardian on that person's behalf. Because of their vulnerability, the elderly should not be included in research unless the research is necessary to promote the health of this population and unless this research cannot instead be performed on legally competent persons.
Research Involving Collectivities
Per the G-EthicsHR-ZAF, a collectivity is a term used to distinguish some distinct groups from informal communities, commercial, or social groups. Collectivities are persons who participate in research in groups distinguished by common beliefs, values, social structures, and other features that identify them as a separate group; customary collective decision-making according to tradition and beliefs; the custom that leaders express a collective view; and members of the collectivity being aware of common activities and common interests. Research involves a collectivity when property or information private to the group as a whole is studied or used; permission of people occupying positions of authority is required; and participation of members acknowledged as representatives is involved. Among other requirements, research involving collectivities should include measures to ensure an informed consent process for individual participants.
Overview
As per the G-AppConductCT and the G-EthicsHR-TZA, in all Tanzanian clinical trials, research participants selected from vulnerable populations must be provided additional protections to safeguard their health and welfare during the informed consent process. Vulnerable populations include those who are incapable of protecting their own interests due to a lack of autonomy, intelligence, education, resources, strength, or other necessary attributes, and have an increased likelihood of being wronged or of incurring additional harm during clinical trials. For example, the G-AppConductCT includes persons who are illiterate, marginalized by their social status or behavior, or living in an authoritarian environment. Vulnerable groups include individuals in hierarchical relationships, institutionalized persons, nomads, refugees or displaced persons, people living with disabilities, people with incurable or stigmatized conditions or diseases, and people faced with physical frailty. The G-EthicsHR-TZA additionally identifies children, mature and emancipated minors, street children, prisoners, the homeless, substance abusers, handicapped (mentally and physically), armed forces, and pregnant women. In some cases, willingness to volunteer to participate in research is unduly influenced by the expectation of benefits associated with their participation, or fear of retaliation from interested senior members of the hierarchy in case of refusal to participate. Characteristics that constitute vulnerability with reference to communities include one (1) or more of the following:
- Limited economic empowerment
- Inadequate protection of human rights
- Discrimination on the basis of health status
- Inadequate understanding of scientific research
- Limited availability of health care and treatment options
- Limited ability in the community to provide informed consent
As per the G-EthicsHR-TZA, clinical trials involving vulnerable persons require additional attention to ensure their protection. Where factors relating to vulnerability are an aspect of the research study, ethics committees (ECs) must ensure that researchers specify how that vulnerability would be addressed, particularly:
- Selection of the particular communities is justified by the research goals
- Research study is relevant to the needs and priorities of the community in which it is to be conducted
- Research study is beneficial to that community
- The community can access products of the research
- Where appropriate, feedback of results should be provided to the community
- Study participants must be fully aware that they are participating in the research and should provide informed consent
- Special attention should be paid to the content, language of the consent document, procedures for obtaining informed consent, monitoring of the process, and testing comprehension
TZA-5 requires the investigator to specify in the clinical trial application if a research protocol involves a vulnerable population or special group, provide adequate justification for their involvement, and provide information on how the participants’ rights and welfare will be safeguarded. Further, the investigator should include information about how they will assess the participants’ capacity to consent for themselves. If the participant is not able to consent, the researcher should include information about how consent will be obtained from the participant’s legal representative/guardian and how assent will be obtained from the participant (where appropriate).
See the Children/Minors; Pregnant Women, Fetuses & Neonates; Prisoners; and Mentally Impaired sections for additional information about these vulnerable populations.
Information on the specific vulnerable populations specified in the G-EthicsHR-TZA is provided below.
Persons Highly Dependent on Medical Care
Per the G-EthicsHR-TZA, persons highly dependent on medical care, such as those living with disabilities (physical or mental) or terminally ill patients, require special attention because they are prone to being socially marginalized. Therefore, their dignity, rights, and well-being in research must be respected. For persons living with disabilities, careful consideration should be made where proxy consent is used, and where the use of signed consent forms is not feasible, alternative viable methods should be employed. Persons living with disabilities should not be unfairly excluded from participating in research. Researchers should make efforts to address communication, disability, and comprehension constraints. (See Mentally Impaired section for requirements on persons with mental disabilities). For terminally ill patients, their dire state may affect their ability to make voluntary decisions regarding participation in research studies. A research protocol involving terminally ill patients as study participants must meet the following additional requirements: the research can only be conducted with terminally ill patients; if the research objectives of the study cannot be addressed using another non-vulnerable group; and the risk-benefit ratio should be favorable to the patients.
Elderly Persons
As per the G-EthicsHR-TZA, it is important to exercise special care when involving the elderly who have been in the hospital or in a residential home for a long time because they may be more dependent on others for their care. Independent, but caring observer(s) for the elderly must be fully informed about the study and be satisfied that the elderly participant understands the intended research activities prior to consent.
As per the G-AppConductCT, TZA-14 should be followed for clinical trials that involve:
- New investigational products that are likely to have significant use in the elderly
- New formulations and new combinations of established medicinal products when there is specific reason to expect that conditions common in the elderly are likely to be encountered and are not already dealt with in current labeling
- New formulation or new combination is likely to alter the geriatric patient’s response in a way different from previous formulations
- New uses that have significant potential applicability to the elderly
Students
The G-EthicsHR-TZA states that research studies involving students can be conducted as long as the following conditions are met:
- The tutor involved in the tuition of the student should not be involved in the recruitment and other negotiations on the terms and research conditions
- The informed consent should clearly state that the student may wish at any stage of the research study to withdraw without any undue consequences
- An impression should not be created that acceptance to participate in the study will benefit the student in the passing of their examinations
- An impression should not be created that non-acceptance will result in discrimination and consequences on the student’s studies
- There should not be any form of coercion, pressure, or financial inducement other than that proposed as reimbursements for participants
Homeless Persons
Per the G-EthicsHR-TZA, the category of homeless persons includes street children, adults staying on the street, refugees, and internally displaced persons. In conducting research with people who are homeless, researchers should be guided by the following principles:
- Research must be conducted with respect to the human rights, welfare, and dignity of study participants
- The research study must be conducted in a non-judgmental way regarding the person’s appearance, strategies for making money, or personal habits
- The right to privacy and security must be respected at all times for people who are homeless
Armed Forces
For research involving participants in the armed forces, the G-EthicsHR-TZA requires the following consent conditions:
- Any possible advantages accruing to participants through their participation in the research study (when compared to the general living conditions, medical care, quality of food, amenities, and opportunity for earnings) are not of such magnitude so that it might impair participants’ ability to weigh the risks of the study against the value of these advantages in the military environment
- The risks involved in the research study are commensurate with the risks that would be accepted by non-armed force volunteer participants
- Procedures for the selection of study participants from within the military are fair to all military personnel and insulated from arbitrary intervention by military authorities or by other members of the armed forces
- The information conveyed to the participants is presented in a language that is understandable to them
- There is adequate assurance that a participant’s participation or refusal to participate in the study will not be considered in decisions regarding their promotion, pay, or any other career opportunities
The SA-GCPs and G-EthicsHR-ZAF stipulate that minors are younger than 18 years old and are regarded as vulnerable persons due to their lack of legal capacity. The G-GPHlthCare-IC states that a person over the age of 18 years is an adult and is legally competent to decide on all forms of treatment and medical procedures. However, a minor who is 12 years of age and older is legally competent to consent to a proposed investigation if the minor is of sufficient maturity and is able to understand the benefits, risks, social, and other implications of the research. A minor's refusal to participate in research must be respected.
Per the SA-GCPs, documented permission from the parent/legal guardian must be obtained in advance prior to approaching the minor to request participation. According to the NHA, the SA-GCPs, the G-GPHlthCare, and the G-GPHlthCare-IC, consent for minors to participate in research must be obtained from:
- The parent/legal guardian in all but exceptional circumstances (such as emergencies)
- The minor/child who is competent to make the decision
- Any organization or person required by law (defined in the NHA)
- Where the minor/child is not competent, assent from the minor/child and consent from the parent/legal guardian
According to the NHA, where research or experimentation is to be conducted on a minor for therapeutic purposes, the study may only be conducted when:
- It is in the best interests of the minor
- It is carried out in such manner and on such conditions as may be prescribed
- The consent of the minor’s parent/legal guardian is provided
Where research or experimentation is to be conducted on a minor for non-therapeutic purposes, the NHA, the NHAParticipants, the SA-GCPs, and the G-MinisterConsent state that a study may only be conducted when:
- It is carried out in such manner and on such conditions as may be prescribed
- The consent of the Minister of Health is provided, or, where appropriate, consent from a delegated authority
- The consent of the minor’s parent/legal guardian is provided
- The consent of the minor is provided when the minor is capable of understanding
The G-EthicsHR-ZAF further indicates that the following are minimum conditions for an ethics committee (EC) to approve research with minors:
- Their participation is scientifically essential to the research and investigate a problem of relevance to minors, and the protocol should provide sufficient information to justify why minors should be included as participants
- Minors should only participate in research where such research poses acceptable risks of harm
- Research involving minors must be reviewed appropriately, including pediatric or child research specialists as reviewers
- Registered ECs’ deliberations are properly documented in minutes and recorded and include EC members with appropriate minor research experience
- Minors should participate in research only when the required written permissions from the parent/legal guardian have been obtained
- When a parent/legal guardian gives permission for their minor to choose whether to participate in research, this permission is given based on a detailed description of all diagnostic and therapeutic interventions that will affect the minor in the study
- The informed consent documentation must explain whether results of tests will be made known to minor participants and their parents
- The minor’s interest in confidentiality must be respected
- The minor’s privacy interests are considered
- Research involving minors must respect their evolving capacity to give consent
- Researchers must familiarize themselves with the legal obligations to report minor abuse and neglect
See the NHAParticipants and G-EthicsHR-ZAF for detailed application requirements.
In addition, per the G-MinisterConsent, the Minister of Health may not give consent if any of the following circumstances apply:
- The study objective(s) can also be achieved if conducted on an adult
- The research is unlikely to significantly improve scientific understanding of the minor’s condition, disease, or disorder to such an extent that it will result in significant benefit to the minor(s)
- The reasons for the consent to the research by the parent/legal guardian and, if applicable, the minor, are contrary to public policy
- The research poses a significant risk to the health of the minor
- The risk to the health or well-being of the minor is not significantly outweighed by the potential benefit
For more information on ministerial consent for non-therapeutic health research with minors, see the operational guidelines at the G-MinisterConsent.
Assent Requirements
The SA-GCPs requires the EC to ensure that adequate steps outlined in the clinical protocol are used to obtain a minor’s assent when, in the EC’s judgment, the minor is capable of providing such assent. When the EC determines that assent is required, it must also indicate whether and how such assent should be documented. A minor’s assent should not be assumed simply because of failure to object during the informed consent process. It is necessary for the minor and the parent/legal guardian to be in agreement on participation. The minor’s refusal to participate is final.
Per the G-EthicsHR-ZAF, the parent/legal guardian does not choose for the minor who has factual capacity to choose, rather, the parent/guardian gives permission for the minor to choose (i.e., to assent to participation). Where a minor is very young (less than seven (7) years old) or is factually incapable of exercising a choice, then the parent/legal guardian chooses whether the minor should participate. When ECs review protocols that involve minors, it is critical to consider whether the required written permissions have been obtained, including assent from the minor in writing preferably (i.e., agreement to participate) if they choose to participate.
See the Personal Data Protection section for requirements on processing personal data of minors.
The ChildAct states that a person less than 18 years of age should be known as a child. As per the G-AppConductCT and the G-EthicsHR-TZA, when the research participant is a child, the informed consent form (ICF) must be signed by the child’s parent/legal guardian.
According to the G-EthicsHR-TZA, research involving greater than minimal risk, but presenting the prospect of direct benefit to a child, may be conducted only if:
- The risk is justified by the anticipated benefit to the child
- The relation of the anticipated benefit to the risk is at least as favorable to the research study participants (children) as that presented by available alternative approaches
- Adequate provisions have been made for the solicitation of the child’s assent and the informed consent of the child’s parent/legal guardian
Further, per the G-EthicsHR-TZA, research that involves greater than minimal risk and entails no prospect of direct benefit to the individual child participant, but is likely to yield generalizable knowledge about the child’s disorder or condition may not be conducted unless:
- The risk represents a minor increase over minimal risk
- The intervention or procedure presents experiences that are commensurate with those inherent in their actual or expected medical, dental, psychological, social, or educational situations
- The intervention or procedure is likely to yield generalizable knowledge about the child’s disorder or condition that is of vital importance for the understanding or amelioration of that disorder or condition
- Adequate provisions have been made for the solicitation of the child’s assent and their parents’/legal guardians’ informed consent
- When the child’s participation is indispensable and participation is not contrary to the child’s best interest
As delineated in the G-EthicsHR-TZA, mature minors are individuals 14 to 17 years of age who are able to demonstrate the ability and capacity to manage their own affairs and to live wholly or partially independent of their parent/legal guardian. This is someone who has not reached adulthood (as defined by country law) but who may be treated as an adult for certain purposes (e.g., consenting to medical care). Emancipated minors refer to persons who have not reached the age of majority (18 years) and are empowered by law to make autonomous decisions. They are free from control by their parent/legal guardian, and the parent/legal guardian is free from the responsibility for the child. Mature and emancipated minors may independently provide informed consent to participate in research if:
- In the ethics committee’s (EC’s) view, the research is not objectionable to parents/legal guardians in the community (established with evidence from the community)
- The research protocol includes clear justification for targeting mature and emancipated minors as participants, and a clear justification for not involving parents/legal guardians in the consent process
The G-AppConductCT delineates that data on the appropriate use of investigational products (IPs) in the pediatric population should be generated unless its use in pediatric patients is clearly inappropriate. The pediatric development program should not delay completion of adult studies and availability of IPs for adults. The decision to proceed with a pediatric development program for an IP and the nature of that program should follow the requirements in TZA-12.
Assent Requirements
The G-EthicsHR-TZA, states that the child’s assent takes precedence over the parent’s/legal guardian’s consent. For all research involving children, there must be no financial or other inducements to participate for the parent, guardian, or child, although reimbursements and a token for the child after completion of the study may be acceptable.
Per the G-EthicsHR-TZA, children and adolescents who are minors cannot give legally-valid informed consent, but they may be able to give assent. To give assent means that the child or adolescent is meaningfully engaged in the research study discussion in accordance with their capacities. Assent must be considered as a process and is not merely the absence of dissent. Furthermore, the researcher must involve the child or adolescent in the actual decision-making process and use age-appropriate information. It is particularly important to inform the child or adolescent and obtain assent as described above, preferably in writing for children who are literate. Specific protections to safeguard children and adolescents’ rights and welfare in the study are necessary. Before undertaking research studies involving children and adolescents, the researcher and the ECs must ensure that:
- A parent/legal guardian of the child or adolescent has given permission
- Assent of the child or adolescent has been obtained, after having been provided with adequate information about the study tailored to the child’s or adolescent’s level of maturity
- If children reach the legal age of maturity during the study period, their consent to continued participation should be obtained
Per the G-EthicsHR-TZA, children or adolescents are required to assent if they are between 10 and 17 years old and can read and write, as well as understand the description of the study. In general, the refusal of a child or adolescent to participate or continue in the study must be respected unless, in exceptional circumstances, where participation is considered the best medical option. For research interventions or procedures that have the potential to benefit children or adolescents, the risks must be minimized and outweighed by the prospect of potential individual benefit. For research interventions or procedures that have no potential individual benefits for children/adolescents, the interventions should be studied in adults first, unless the necessary data cannot be obtained without participation of children/adolescents and the risks are minimized.
As per the NHA and the G-EthicsHR-ZAF, any research studies involving pregnant women, women who may become pregnant, or fetuses, require additional safeguards to ensure the research conforms to appropriate ethical standards and upholds societal values. The ethics committee (EC) must provide particular attention to these participants due to the potential for additional health concerns that may arise during pregnancy, and the need to avoid unnecessary risk to the fetus.
The G-EthicsHR-ZAF states that any proposed exclusion of women participants must be justifiable in light of research priorities as well as the specific research question under consideration. Systematic class exclusion must be guarded against to avoid unfair participant selection. Additional health concerns arise during pregnancy, including the need to avoid unnecessary risk to the embryo, fetus, or infant; however, automatic exclusion of pregnant women should be avoided to prevent data inequities for pregnant and nursing women. Researchers and ECs should exercise extra caution when women participants are or may become pregnant. Exclusion of women from research may be justifiable to protect the health of the embryo, fetus, or infant and if exclusion is scientifically supportable. The informed consent documents must explain carefully and fully what the effects of the research activities on the embryo, fetus, or infant might be. Usually, research involving pregnant women should be undertaken when:
- The purpose of the proposed research is to meet the health needs of the mother of the embryos, fetuses, or infants
- Appropriate studies on animals and nonpregnant women have been completed
- The risk of harm to the embryo, fetus, or infant is minimal, when procedures or interventions have no potential individual benefit for the women or embryo, fetus, or infant
- The risk of harm is outweighed by the prospect of potential individual benefit, when procedures or interventions have potential individual benefit for the women or embryo, fetus, or infant
- In all cases, inclusion poses the least risk of harm possible for achieving the objectives of the research
The SA-GCPs stipulates that pregnant women, women planning to become pregnant, or breastfeeding women are usually excluded from human clinical trials where a new chemical entity (NCE) or medicines with no information on safety in pregnancy/lactation are investigated for treatment of a particular disease/condition or disorder. However, when safety and other relevant information is available, pregnant or breastfeeding women should be included in clinical trials to ensure that appropriate knowledge about NCEs for this group is developed.
The G-AppConductCT recommends that women of child-bearing potential be included at the earliest possible stages of clinical trial research so that potential sex-related differences are identified and taken into consideration when planning Phase III trials. The timing of including women of childbearing potential or pregnant women in clinical trials should comply with guidance in the International Council for Harmonisation's Guidance on Nonclinical Safety Studies for the Conduct of Human Clinical Trials and Marketing Authorization for Pharmaceuticals (TZA-15). Any research involving pregnant women should be individualized and based on a careful risk/benefit assessment, considering:
- The nature and severity of the disease
- The availability and results of previous nonclinical and clinical data
- The availability of alternative therapy and knowledge about their risks
- The stage of pregnancy in relation to the overall development of the fetus, especially regarding fetal brain development
- The potential for harm to the woman, the fetus, or child
- The long-term follow up of the pregnancy, fetus, and child, when possible
Additional considerations for including pregnant women in clinical trials are provided in the G-AppConductCT.
The G-AppConductCT identifies the following considerations for deciding whether to include breastfeeding women in clinical trials:
- A new indication is being sought for an approved therapeutic product and there is evidence of use or anticipated use by breastfeeding women
- After market authorization, use of a therapeutic product in breastfeeding women becomes evident
- There is concern that the consequences of uninformed dosages for use while breastfeeding are potentially serious and/or severe
- A therapeutic product is under review for market authorization and is expected to be used by women of reproductive age
- The trial involves marketed medications that are commonly used by women of reproductive age
- The risk to the infant or mother is not greater than that from established procedures routinely used during breastfeeding, is comparable to those being studied, and the purpose of the research is the development of biomedical knowledge which cannot be obtained by any other means
As per the G-EthicsHR-TZA, research studies relating to pregnant women or fetuses may be undertaken under the following conditions:
- The risk to the fetus is minimal and is the least possible risk for achieving the objectives of the research study, except where the purpose of the research study is to meet the health needs of the mother and the fetus, and the foreseeable benefits outweigh the potential risks
- No procedural changes that could cause greater than minimal risk to the fetus or to the pregnant woman may be introduced into the procedure for termination of the pregnancy
- No inducements, whether financial or any other form, may be offered to terminate the pregnancy for the purposes of the research study
- Appropriate studies on animals and non-pregnant individuals have been completed
- The purpose of the proposed research is to meet the health needs of the mother and the fetus will be placed at risk to the minimum extent necessary to meet these needs or the risk to the fetus is minimal
- The mother and the father are both legally competent and have been fully informed of the possible impact on the fetus and have given their informed consent to proceed; however, the father’s consent is not required if the purpose of the research is primarily to meet the health needs of the mother, the father’s identity and/or whereabouts are unknown, the father is not available, or the pregnancy resulted from rape or incest
According to the NHA, the G-EthicsHR-ZAF, and the NHAParticipants, a prisoner may not, even with consent, participate in any scientific experimentation, research study, or clinical trial except under limited conditions. Per the G-EthicsHR-ZAF, prisoners are considered a vulnerable class of persons because of the potential effect of incarceration on the voluntariness of the decision to participate in research. Neither coercion nor undue influence is acceptable in the informed consent process. Researchers should pay attention to whether their intended participants are prisoners who are awaiting trial or are convicted as different ethical issues arise for each group. The recruitment strategy design must pay careful attention to how coercion and undue influence will be avoided. Similarly, persons administering questionnaires or conducting interviews must be conscious of environmental factors that may influence voluntariness. The ethics committee (EC) should include, at least on an ad-hoc basis, a member with experience and knowledge of working with prisoners when deliberating on the protocol.
Per the G-EthicsHR-ZAF, research should be conducted on prisoners only if:
- Their participation is indispensable to the research
- The research cannot be conducted with non-prisoners
- The research concerns a problem of relevance to prisoners
- Sound informed consent processes can be ensured
- Engagement with relevant role players about the proposed research has occurred
Generally, it is unlikely that independent consent by minor prisoners will be justifiable.
According to the G-EthicsHR-TZA, prisoners are vulnerable to abuse by research because their freedom for consent can easily be undermined, which could affect their ability to make a voluntary decision regarding their participation in research. Research involving prisoners may not be approved unless the proposed research has the intent and a reasonable probability of improving the health and well-being of the study participants, and appropriate knowledgeable persons in penology, medicine, and ethics have been consulted in the course of reviewing the research protocol. Further, research with prisoners can be conducted only if:
- The research offers a distinctly favorable benefit to risk ratio, not because the prisoners are a convenient source of participants
- The research improves the well-being of prisoners while taking great care to protect their health, well-being, and human rights
- The ethics committee (EC) reviews and verifies that the criteria for permissible research are satisfied
- EC members have no association with the prison(s) involved other than their status as members of the EC reviewing the proposed research study
- Where possible, a prisoner or an ex-prisoner should be co-opted to the EC in reviewing the proposed research study
- The risks involved in the research study are commensurate with risks that will be accepted by non-prisoner volunteers
- The procedure for selecting participants in the prison are fair to all prisoners
- There is adequate assurance that a prisoner’s participation or refusal to participate will not be considered in decisions regarding their release or further detention and each prisoner is clearly informed in advance that participation in the research study will have no effect on their release
- Any possible advantages accruing to the prisoner through participation in the research study, when compared to the general living conditions, medical care, quality of food, amenities, and opportunity for earnings in the prison, are not of such magnitude that the prisoner’s ability to weigh the risks of the research against the value of these advantages in the prison environment is impaired
According to the NHA, the SA-GCPs, the G-EthicsHR-ZAF, the G-GPHlthCare, and the NHAParticipants, sufficient justification must be provided for any research or treatment involving a participant who has a mental or intellectual impairment or substance abuse related disorder, and the research must be relevant to the mental disability or substance abuse disorder.
Per the G-EthicsHR-ZAF, research involving adults with incapacity should be approved only if:
- The research, including observational research, is not contrary to the best interest of the individual
- The risk of harm assessment shows that the research, including observational research, places the incapacitated adult at no more than minimal risk
- The research involves greater than minimal risk but provides the prospect of direct benefit for the incapacitated adult; the degree of risk must be justified by the potential benefit
- The research, including observational research, involves greater than minimal risk, with no prospect of direct benefit for the incapacitated adult, but has a high probability of providing generalizable knowledge (i.e., the risk should be justified by the risk-knowledge ratio)
- Greater than minimal risk must represent no more than a minor increase over minimal risk
- Where appropriate, the person assents to participation (Note that the incapacitated person’s refusal or resistance to participate, as indicated by words or behavior, takes precedence over permission by a proxy)
As delineated in the G-EthicsHR-ZAF, proxy decision-makers for incapacitated adults are not permitted in South African law unless the proxy is a court appointed curator or holds a statutory mandate to make health care decisions for the now incapacitated person pursuant to the NHA. Incapacity may not be assumed but requires independent and objective assessment by appropriately trained persons. If the research participant regains capacity to make decisions, they must be informed that they have been enrolled in a research study. If they object to having been enrolled in the research study, this counts as a refusal to participate, and their data must be withdrawn. If the participant does not object, personal consent may be desirable depending on the length and complexity of the study.
As indicated in the G-EthicsHR-TZA, persons living with mental disabilities require special attention because they are prone to being socially marginalized, and therefore, their dignity, rights, and well-being in research must be respected. Careful consideration should be made where proxy consent is used. Where the use of signed consent forms is not feasible, alternative viable methods should be employed. Persons living with disabilities should not be unfairly excluded from participating in research. Researchers should make efforts to address communication, disability, and comprehension constraints. Persons with mental health conditions including psychiatric, cognitive, or developmental conditions, and substance abuse related disorders at times may be hospitalized or institutionalized, which may further compromise their ability to make voluntary decisions to participate in a research project. Research must not be conducted if the purpose of the research is not relevant to the particular health needs of persons living with disabilities, or alternative interventions exist that are at least as advantageous to the individual participant as that under the proposed study. Further, the following should be scrutinized:
- There is sufficient justification for inclusion
- There are appropriate evaluation procedures for ascertaining study participants’ ability to give informed consent; if such study participants are deemed unable to understand and to make an informed decision, then an appropriate proxy should be identified
- An informed consent process that is free from coercion
- Be of no more than minimal risk; if minimal risk is involved, the risk is outweighed by the anticipated benefits of the research study to the participants
The G-EthicsHR-TZA outlines the requirements to safeguard the rights and welfare of adults who are incapable of giving informed consent in research studies. Before undertaking research with adults who are not capable of giving informed consent, the researcher and the EC must ensure that:
- A legal representative of the person who is incapable of giving informed consent has given permission and this permission takes account of the participant’s previously formed preferences and values (if any)
- The assent of the participant has been obtained to the extent of that person’s capacity, after having been provided with adequate information about the study at the level of the participant’s capacity for understanding this information
- If participants become capable of giving informed consent during the study, their consent to continued participation must be obtained; in general, a potential participant’s refusal to enroll in the study must be respected, unless in exceptional circumstances where study participation is considered the best available medical option for an individual who is incapable of giving informed consent
As delineated in the SA-GCPs and the PIC-S-GMP-Guide (which South Africa adopted pursuant to the SA-GMPs), an investigational product is defined as a pharmaceutical form of an active ingredient or placebo being tested or used as a reference in a clinical trial. This includes:
- A product with a marketing authorization when used or assembled (formulated or packaged) in a different way from the approved form
- When used for an unapproved indication
- When used to gain further information about an approved use
As delineated in the G-AppConductCT, an investigational medicinal product (IP) is defined as a pharmaceutical form of an active ingredient or placebo being tested or used as a reference in a clinical trial. Further, per the G-EthicsHR-TZA, an IP refers to a preventative (vaccine), therapeutic (drug or biologic), device, diagnostic, or palliative used in a clinical trial. The G-AppConductCT and the G-EthicsHR-TZA state that an IP includes:
- A product with a marketing authorization when it is used or assembled (formulated or packaged) in a different way from the approved form
- When used for an unapproved indication
- When used to gain further information about an approved use
Manufacturing
According to the SA-GMPs and the GRMRSA, the South African Health Products Regulatory Authority (SAHPRA) is responsible for authorizing the manufacture of investigational products (IPs) in South Africa. As delineated in the G-ManuImpExp, a manufacturer’s license for IPs is required for both total and partial manufacture, and for the various processes of dividing up, packaging, or presentation, in accordance with the MRSA. To obtain a license, the application form (ZAF-55) should be emailed to SAHPRA at gmplicensing@sahpra.org.za, accompanied by the following information:
- Proof of payment
- Existing SAHPRA license for renewal and amendment applications
- Cover letter
- Site Master File
- Signed declaration
- SAHPRA inspection resolution
- Intellectual property documentation
- Department of Health premises license
- Registration of responsible pharmacist
- South African Pharmacy Council (SAPC) Record of a Pharmacy
- SAPC Record of a Pharmacy Owner
- Municipal Approval/Zoning Certificate
Per ZAF-55, the license is valid for five (5) years and the application to renew the license must be submitted at least 180 days before the expiration of the current license.
In addition, per ZAF-23, a clinical trial application to SAHPRA must include a certificate of good manufacturing practice (GMP) for manufacture of the IP(s). The SA-GCPs also states that the sponsor must ensure that the IP (including active comparator and placebo, if applicable) is manufactured in accordance with applicable GMP standards.
Pursuant to the SA-GMPs, South Africa adopted the PIC-S-GMP-Guide for the manufacturing of therapeutic goods. The PIC-S-GMP-Guide includes requirements for a Certificate of Analysis to be issued by the manufacturer for all IPs to be used in a clinical trial. For GMP agreements with competent international regulatory authorities, the SA-GMPs states that these agreements do not permit automatic acceptance but may be used to enhance regulatory oversight and compliance. SAHPRA may request additional documentation and/or schedule an inspection to ensure GMP compliance. The following conditions demonstrate GMP compliance:
- The site has been approved by a recognized regulatory authority (RA) within the previous three (3) years
- The dosage form of the IP within the application is within the same dosage form grouping as the dosage form approved by the RA
- The product type applied for is the same as the product type approved by the recognized RA
- The activities applied for by the applicant are the same activities that have been approved by the recognized regulator
Import
The SA-GCPs states that IPs may be imported into South Africa only after approval of the protocol by SAHPRA. Samples of the IP to be imported before trial approval require a SAHPRA license under MRSA. The sponsor must ensure that the IP (including active comparator and placebo, if applicable) is manufactured in accordance with any applicable GMP standards. Per G-ManuImpExp to import an IP, the applicant must submit an application form (ZAF-55) to SAHPRA.
The CTA-Import indicates that there have been delays in the release of IPs at the SAHPRA border control because the import licenses (clinical trial approval letters) have not specified the quantities of study medication authorized for importation. To address this problem, a protocol amendment application (ZAF-20) is required to request the approval of the remaining study medication to be imported for these specific trials. Applicants will be allowed six (6) months from the date of the CTA-Import (i.e., from September 19, 2024) to obtain the necessary approvals.
Per the G-ImprtPorts, SAHPRA’s Regulatory Compliance Unit is responsible for ensuring that health products at ports of entry meet importation requirements under MRSA, including for IPs. Imported IPs must be accompanied by the certificate of registration that proves authorization under the MRSA.
Please note: South Africa is party to the Nagoya Protocol on Access and Benefit-sharing (ZAF-8), which may have implications for studies of IPs developed using certain non-human genetic resources (e.g., plants, animals, and microbes). For more information, see ZAF-34.
Manufacturing
According to the TMMDAct, the CT-Regs, and the G-AppConductCT, the Tanzania Medicines and Medical Devices Authority (TMDA) is responsible for authorizing the manufacture of investigational products (IPs) in Tanzania. The TMDA will approve the manufacture of an IP after the clinical trial application has been approved via the Regulatory Information Management System (RIMS) Customer Self Service Portal (TZA-34). Regarding inspection frequency, the GMP-Insp and TZA-19 state that a domestic manufacturing facility must be inspected once a year to renew its annual business permit. The GMP-Insp also states that a manufacturing facility must be inspected once every three (3) years. However, a facility may be inspected at any time when necessary. See the G-AppConductCT for details on the quality requirements for manufacturing IPs.
Per the GMP-Insp, domestic and foreign manufacturing facilities of human medicinal products must comply with the good manufacturing practice (GMP) in the latest versions of the World Health Organization (WHO)’s Technical Report Series (WHO-TRS). In addition, other guidelines—such as those by the International Council for Harmonisation of Technical Requirements for Pharmaceuticals for Human Use and Pharmaceutical Inspection Co-operation Scheme—may be used as supplementary guidance when establishing compliance of facilities to GMP requirements. See the GMP-Insp for additional details and information on the inspection of manufacturing facilities of human medicinal products.
Import
Per the TMMDAct, the CT-Regs, the TFDCA-ImptExpt, the G-AppConductCT, and the G-ImpExp, the TMDA is also responsible for authorizing the import of IPs. As per the TMMDAct, the TFDCA-ImptExpt, and the G-ImpExp, the sponsor or the principal investigator (PI) may apply for an import license once the clinical trial application has been approved by the TMDA. The TFDCA-ImptExpt specifies that in order to be granted an import license, the applicant must:
- Have a pharmacist registered by the Pharmacy Council who must be a Superintendent of the business
- Have premises registered by the TMDA
- Hold a valid business permit
The G-ImpExp states that importation of pharmaceutical products and raw materials must be done by importers whose premises are registered by the TMDA or the relevant government institutions. All importers should import pharmaceutical products and raw materials through authorized ports of entry. A person must not import any pharmaceutical product with a shelf life of more than 24 months whose remaining shelf life is less than 60%, or a pharmaceutical product with a shelf life of less than or equal to 24 months whose remaining shelf life is less than 80%.
The TFDCA-ImptExpt specifies that the import license application should be accompanied by the clinical trial approval letter issued by the TMDA. The applicant must fill out the Application for Importation of Pharmaceutical Products provided in the First Schedule of the TFDCA-ImptExpt and pay the fee pursuant to the TMMDAFees. In addition, the application should be accompanied by three (3) copies of the proforma invoice numbered, dated, and signed by the superintendent of the business. (A proforma invoice is an abridged or estimated invoice sent in advance of a shipment or delivery of goods.) The proforma invoice should include the following:
- Name and address of the supplier
- Name and address of the manufacturer of each product
- Trade or proprietary name of each product
- The international nonproprietary name (generic name) of the drug and its strength
- In the case of the product containing more than one (1) active ingredient, the name and strength of each product
- The pharmacopoeia specification of the ingredient of each product
- Product registration number issued by the authority for each product
- The quantity, pack size, unit value, and total value in convertible currency
- Batch or lot number where applicable for each product
- Manufacturing and expiration date, where applicable, for each product
- Mode of shipment (sea, air, or road)
- Authorized port of entry
- Signature and stamp of the supplier
Per TZA-34, the import license application can be submitted to the TMDA via TZA-34, which can be accessed by first creating a trader account. An online access registration form is available in Annex I of the G-ImpExp.
As delineated in the TFDCA-ImptExpt and the G-ImpExp, the import permit is valid for six (6) months, not transferable, and issued to cover only one (1) shipment. Per the G-ImpExp, in the case of partial shipments, two (2) shipments may be allowed based on the initial import permit. See the TFDCA-ImptExpt and the G-ImpExp for detailed import application requirements.
The TFDCA-ImptExpt and the G-ImpExp identify the authorized ports of entry for pharmaceutical products imported into Tanzania. The TFDCA-ImptExpt states that an importer must provide all necessary documents as may, from time to time, be requested by the inspector. When it is deemed necessary to collect samples or where the inspector suspects that any product may contravene any regulation or law, the inspector may take samples for further investigation.
Investigator’s Brochure
In accordance with the SA-GCPs, the sponsor is responsible for ensuring an up-to-date Investigator’s Brochure (IB) is available to the investigator; investigators must provide it to the responsible ethics committee (EC). In the case of an investigator-sponsored trial, the sponsor-investigator must determine whether an IB is available from the commercial manufacturer.
The SA-GCPs states that the IB should contain the following sections, each with literature references where appropriate:
- Table of Contents
- Summary: A brief summary (preferably not exceeding two (2) pages) to highlight the significant physical, chemical, pharmaceutical, pharmacological, toxicological, pharmacokinetic, metabolic, and clinical information available that is relevant to the stage of clinical development of the investigational product (IP)
- A brief introductory statement with the chemical name (and generic and trade name for an approved product) of the IP, all active ingredients in the IP, its pharmacological class and expected position within this class (e.g., advantages), the rationale for conducting research with the IP, and the anticipated prophylactic, therapeutic, and/or diagnostic indications. Also include a description of the general approach to be followed in evaluating the IP.
- Physical, chemical, and pharmaceutical properties and formulation parameters
- Pre-clinical studies (pharmacology, pharmacokinetics, toxicology, and metabolism profiles)
- Effects of IP in humans (pharmacology, pharmacokinetics, metabolism, and pharmacodynamics; safety and efficacy; regulatory and postmarketing experiences)
- Summary of data and guidance for the investigator(s)
Quality Management
As defined in the SA-GCPs, the sponsor must ensure that IPs are manufactured in accordance with good manufacturing practice (GMPs), including the requirements in Annex 13 of the PIC-S-GMP-Guide (which South Africa adopted pursuant to the SA-GMPs). (See Product Management section for additional information on IP supply, storage, and handling requirements). As indicated in ZAF-23, the following information must be furnished in the clinical trial application:
- Whether the IP contains an active substance of chemical origin or of biological/biotechnological origin
- IP name(s) and details (e.g., formulation(s) and strength(s))
- Properties of the IP (e.g., mechanism of action)
- Summary of pre-clinical findings (e.g., laboratory, animal, toxicity, or mutagenicity)
- Summary of clinical findings
- Comparator product(s) name(s) and details
- Concomitant name(s) and details including rescue medications
- Registration status of IP, concomitant, and/or comparator medicine(s); include the IB, South African Health Products Regulatory Authority (SAHPRA)-approved principal investigator (PI), and other international professional information (package inserts) if not approved in South Africa, and a Certificate of Analysis (CoA)
- Whether the IP is modified in relation to its original registration for the purpose of the clinical trial
- Estimated quantity of trial material (each drug detailed separately) for which exemption will be required, including for concomitant medicines to be imported
- Explanation for use of imported drugs when the same product is available in South Africa
- Details of receiving the drugs from supplier including storage, dispensing, and packaging of drugs
- Details of intention to register the IP or explain if registration is not envisioned
- Details of the manufacture, quality control, and stability of the IP (including IP destruction process) and include GMP certificate
- Previous studies using this medicine that have been approved by the SAHPRA, including the SAHPRA approval number, study title, protocol number, date of approval, national PI/PI, date(s) of progress report(s), and date of final report
See ZAF-23 for detailed instructions on IP submission requirements.
Per the PIC-S-GMP-Guide (which South Africa adopted pursuant to the SA-GMPs), the release of IPs should not occur until after the authorized person has certified that the relevant requirements have been met. CoAs should be issued for each batch of intermediate or active pharmaceutical ingredient, on request. CoAs should be dated and signed by authorized personnel of the quality unit(s) and should show the name, address, and telephone number of the original manufacturer. See the PIC-S-GMP-Guide for certification requirements.
Investigator’s Brochure
In accordance with the CT-Regs and the G-AppConductCT, the Tanzanian government follows the International Council for Harmonisation's (ICH) Guideline for Good Clinical Practice E6(R2) (TZA-13), and requires the sponsor or the designated contract research organization (CRO) to provide investigators with an Investigator’s Brochure (IB). The G-AppConductCT states that the IB should be presented in a concise, simple, objective, balanced, and non-promotional form that enables a clinician, or potential investigator, to understand it and make an unbiased risk-benefit assessment of the appropriateness of the proposed trial. The contents of the IB should be approved by the disciplines that generated the described data and a medically qualified person should generally participate in the editing of an IB. If the investigational product (IP) is locally marketed and its pharmacology is well established and widely understood by medical practitioners, an extensive IB may not be necessary, and a current summary of product characteristics may be submitted as an alternative. If a marketed product is being studied for a new use (i.e., a new indication), an IB specific to that new use should be prepared. The IB should be reviewed at least annually and revised as necessary in compliance with a sponsor’s written procedures. More frequent revision may be appropriate depending on the stage of development and the generation of relevant new information.
TZA-13 specifies that the IB must contain all of the relevant information on the IP(s) obtained through the earlier research phases, including preclinical, toxicological, safety, efficacy, and adverse event data. Per the CT-Regs, the sponsor should also update the IB as significant new information becomes available and maintain records of each change.
TZA-13 requires the IB to provide coverage of the following areas:
- Physical, chemical, and pharmaceutical properties and formulation parameters
- Non-clinical studies (pharmacology, pharmacokinetics, toxicology, and metabolism profiles)
- Effects of IP in humans (pharmacology, pharmacokinetics, metabolism, and pharmacodynamics; safety and efficacy; regulatory and post-marketing experiences)
- Summary of data and guidance for the investigator(s)
- Bibliography
See Section 7.3 of TZA-13 for detailed content guidelines.
Quality Management
Per the G-AppConductCT, the sponsor must document details regarding the chemistry, manufacturing, and control of the IP as prescribed in Module 3. This should include data to demonstrate the quality of the IP, including relevant batch analyses results. If a comparator medicinal product is used, the proprietary name of the medicinal product, non-proprietary or common name of the active pharmaceutical ingredient, company name, country from which the clinical supplies were obtained (as well as the market status in that country), dosage form(s), and strength(s) should be listed. Batch analysis results for the active pharmaceutical ingredient may be provided in either the quality summary or by providing a copy of the certificate of analysis. The certificate of good manufacturing practice should also be included in the clinical trial application.
As delineated in the GMP-Insp, domestic and foreign manufacturing facilities of human medicinal products must comply with good manufacturing practice (GMP) in the latest versions of the World Health Organization’s Technical Report Series (WHO-TRS). In addition, other guidelines—such as those by the ICH and Pharmaceutical Inspection Co-operation Scheme—may be used as supplementary guidance when establishing compliance of facilities to GMP requirements. The manufacturing facilities are subject to inspection by the Tanzania Medicines and Medical Devices Authority (TMDA). The GMP-Insp describes the types of inspections, inspection fees, and other procedures. If the TMDA finds noncompliance, the manufacturer must prepare and implement a Corrective Action and Preventive Action plan (CAPA). The CAPA plan must be prepared based on quality risk management principles and submitted to the TMDA. The CAPA report must indicate root cause analysis, corrections, corrective actions and preventive actions, timelines, and evidence of implementation for each non-compliance observation. Manufacturers must be allowed a maximum of two (2) rounds to submit CAPA responses. The first CAPA response must be submitted within 90 calendar days of the TMDA’s inspection report cover letter. If the assessment of the first CAPA response is deemed to be non-satisfactory, the manufacturer will have an opportunity to submit a second CAPA response within 60 calendar days. If the assessment of the second CAPA response is still non-satisfactory, the facility must be re-inspected. If the company fails to submit CAPA report within the prescribed period without any request for extension, the facility is deemed non-compliant.
Investigational product (IP) labeling in South Africa must comply with the requirements set forth in the SA-GCPs, the GRMRSA, MRSA, and the PIC-S-GMP-Guide (which South Africa adopted pursuant to the SA-GMPs). The GRMRSA states that for an IP to be used in a clinical trial, it must be properly labeled in English and at least one (1) other official language, and should appear in clearly legible and indelible letters. As set forth in the PIC-S-GMP-Guide, the following labeling information must be included on both the outer packaging and the immediate container:
- The name, address, and telephone number of the sponsor, contract research organization (CRO), or investigator
- The pharmaceutical dosage form, route of administration, quantity of dosage units, and in the case of open trials, the name/identifier and strength/potency
- The batch and/or code number to identify the contents and packaging operation
- A trial reference code allowing identification of the trial, site, investigator, and sponsor (if not given elsewhere)
- The trial participant identification number/treatment number and where relevant, the visit number
- The investigator name (if not already included above)
- Directions for use (reference may be made to a leaflet or other explanatory document intended for the trial participant or person administering the product)
- “For clinical trial use only” or similar wording
- The storage conditions
- The period of use (use-by date, expiration date, or re-test date as applicable), in month/year format and in a manner that avoids any ambiguity
- “Keep out of reach of children” except when the product is for use in trials where the product is not taken home by the participant
In addition, precautions against mislabeling should be intensified by trained staff (e.g., label reconciliation, line clearance, and in-process control checks by appropriately trained staff).
The SA-GCPs specify that in blinded trials, the IP should be coded and labeled in a manner that protects the blinding. The IP(s) coding system should include a mechanism that permits rapid IP(s) identification in case of a medical emergency but does not permit undetectable breaks of the blinding.
Investigational product (IP) labeling in Tanzania must comply with the requirements set forth in the CT-Regs, the TFDCA-ImptExpt, and the G-ImpExp. The TFDCA-ImptExpt and the CT-Regs state that for an IP to be used in a clinical trial, it must be properly labeled in English or Kiswahili (also known as Swahili) language or both, and the information printed on the labels must be indelible, engraved, or embossed on a primary and secondary container.
As set forth in the CT-Regs, the TFDCA-ImptExpt, and the G-ImpExp, the following information must be included on the label (Note: Each of the items listed below will not necessarily be found in all sources, which provide overlapping and unique elements):
- Statement indicating that the product is for “clinical trial purpose only”
- Name, number, or identifying mark
- Recommended storage conditions
- Sponsor name and address
- Protocol code or identification
- Trade or brand name where appropriate
- International Non-Proprietary Name (INN, Generic name)
- Active ingredient quantities listed in the formulation
- Manufacture and expiration dates
- Batch or lot number
- Storage conditions
- Manufacturer name and address
- Product registration number issued by the Tanzania Medicines and Medical Devices Authority (TMDA) included in the outer and inner packaging, where applicable
- Immediate outer packaging and the enclosed and accompanying literature must be in English or Kiswahili
- Active pharmaceutical ingredient specification (BP, USP, etc.)
According to the CT-Regs, where applicable, investigational medicinal products must be labeled in a manner that protects the blinding. Also, re-labelling of any remaining investigational medicinal product from previously manufactured batches must be performed in accordance with established written procedures and good manufacturing practice principles.
Per the G-EthicsHR-TZA, the sponsor is responsible for proper labelling of the IP(s). The investigational and comparator products must be labelled in conformity with the research protocol and the labelling must state that the product is for investigational purposes only.
Supply, Storage, and Handling Requirements
As defined in the SA-GCPs, the sponsor is responsible for supplying a sufficient quantity of the investigational product (IP) after the sponsor obtains study approvals from the South African Health Products Regulatory Authority (SAHPRA) and the ethics committee (EC). The sponsor must ensure that written procedures include instructions and relevant documents for the investigator to follow for handling and storage of the IP for the trial. The procedures must address adequate and safe receipt, handling, storage, dispensing, retrieval of unused product from participants, and return of unused IP to the sponsor (or alternative disposition if authorized by the sponsor and in compliance with the SAHPRA-approved protocol). In addition, the sponsor must:
- Ensure timely delivery of the IP to the investigator
- Maintain records that document shipment, receipt, disposition, return, and destruction of the IP
- Maintain a system for retrieving the IP and then documenting such retrieval (e.g., for deficient product recall, reclaim after trial completion, and expired product reclaim)
- Maintain a system for disposal of unused IP and for its documentation
- Take steps to ensure that the IP is stable over the period of use
- Maintain sufficient quantities of the IP used in the trials to reconfirm specifications, if necessary, and maintain records of batch sample analyses and characteristics; to the extent that IP stability permits, samples should be retained until analyses of trial data are complete or as required by the applicable regulatory requirement(s), whichever is longer
- Provide and maintain a system for retrieving and disposing of trial-related waste (e.g., syringes and needles)
Per the SA-GCPs, the sponsor should determine acceptable temperatures, conditions, times for IP storage, reconstitution fluids/procedures, and devices for product infusion, if any, that comply with the SA-GPPs. The sponsor must inform all parties involved (e.g., monitors, investigators, pharmacists, storage managers) of these determinations.
The SA-GCPs specify that if significant formulation changes are made in the IP(s) or comparator product(s) during the course of clinical development, the results of any studies of the newly formulated product(s) should be made available prior to its use in the clinical trial. Refer to the SA-GCPs for detailed sponsor-related IP requirements.
Regarding packaging, the PIC-S-GMP-Guide indicates that IPs are normally packed individually for each participant in the clinical trial. The number of units to be packaged should be specified prior to the start of the packaging operations, including units necessary for carrying out quality control and any retention samples to be kept. Sufficient reconciliations should take place to ensure the correct quantity of each product required has been accounted for at each stage of processing. During packaging, the risk of product mix up must be minimized by using appropriate procedures and/or, specialized equipment as appropriate and relevant staff training. The packaging must ensure that the IP remains in good condition during transport and storage at intermediate destinations. Any opening or tampering of the outer packaging during transport should be readily discernible. Similarly, the SA-GCPs state that the IPs must be suitably packaged in a manner that will prevent contamination and unacceptable deterioration during transport and storage.
Record Requirements
Per the SA-GCPs, the sponsor, or other data owners, must retain all essential documents pertaining to the trial for not less than 10 years or until at least two (2) years have elapsed since the formal discontinuation of clinical development of the IP. In addition, the sponsor should obtain the investigator’s agreement to retain trial-related essential documents until the sponsor informs the investigator/institution that these documents are no longer needed.
Supply, Storage, and Handling Requirements
Per the G-AppConductCT, the sponsor must obtain approval from the Tanzania Medicines and Medical Devices Authority (TMDA) for the investigational product (IP) dossier in the clinical trial application and any changes to the IP that relate to the chemistry and manufacturing information that may affect drug safety and quality. For example, specifications for the IP where limits of the test are relaxed or deleted; where a new impurity or degradation product has been identified; and addition of new raw materials, solvents, reagents, catalysts, or any other materials used in the manufacture of the active pharmaceutical ingredient.
The G-AppConductCT requires researchers to comply with the CT-Regs and the International Council for Harmonisation's Guideline for Good Clinical Practice E6(R2) (TZA-13). Per TZA-13, the sponsor must supply the investigator(s)/institution(s) with the IP(s), but not until the sponsor obtains approvals from the TMDA and an ethics committee. The sponsor must ensure the following:
- IP product quality and stability over the period of use
- IP manufactured according to any applicable Good Manufacturing Practices (GMPs)
- Proper coding, packaging, and labeling of the IP(s)
- Records maintained for document shipment, receipt, disposition, return, and destruction of the IP(s)
- Acceptable storage temperatures, conditions, and times for the IP
- Timely delivery of the IP(s)
- Written procedures including instructions for handling and storage of the IP(s), adequate and safe receipt of the IP(s), dispensing of the IP(s), retrieval of unused IP(s), return of unused IP(s) to the sponsor, and disposal of unused IP(s) by the sponsor
- Maintain sufficient quantities of the IP(s) to reconfirm specifications, should this become necessary
See the GSDP-Reg and the G-GSDP for requirements and guidance on good storage and distribution practice, including on quality management, the design of premises, receiving areas, storage practices and conditions, stock control and rotations, and traceability of products.
The G-AppConductCT further requires the sponsor to be responsible for the destruction of unused and/or returned IPs. IPs should not be destroyed without prior written authorization by the sponsor. The delivered, used, and recovered quantities of product should be recorded, reconciled, and verified by or on behalf of the sponsor for each trial site and each trial period. Destruction of unused IPs should be carried out for a given trial site or a given trial period only after any discrepancies have been investigated and satisfactorily explained and the reconciliation has been accepted. Requests to dispose IPs must be made to and authenticated by the TMDA. The destruction must be done in accordance with applicable environmental regulations.
The TFDCA-ImptExpt requires that every importer or exporter of a pharmaceutical product must, in respect to the premises, make available the following information to the TMDA: an appropriate inventory control system; an inspection reports file; procedures for handling complaints; and registers for unfit medicines, controlled drugs, recalls, and customers. Further, an importer should maintain the following documents on the premises for a period of not less than one (1) year after the expiration date of the pharmaceutical product: final invoices with corresponding import permits; copies of delivery notes; and sales invoices.
Per the G-EthicsHR-TZA, the sponsor must:
- Provide to the ethics committee (EC) and all other regulatory authorities, a description of the investigational and comparator drugs and a dossier
- Ensure that the IP and any comparator products are of appropriate quality and are subject to quality assurance procedures
- Promptly provide the investigator with any relevant new information that arises during the course of the trial, including information relating to IP safety
- Be responsible for proper packaging and labelling of the IP
- Retain sufficient samples of each batch of the IP and a record of analyses and characteristics so that, if necessary, an independent laboratory may check the product for quality control or bioequivalence
Record Requirements
As set forth in the G-AppConductCT, which complies with TZA-13, the sponsor must ensure maintenance of the following:
- Records documenting IP(s) handling, storage, shipment, receipt, disposition, return, and destruction
- A system for retrieving IPs and documenting this retrieval
- A system to dispose of unused IP(s) and corresponding documentation
- Sufficient quantities of the IP(s) used in the trial to reconfirm specifications, should this become necessary, and maintenance of records of batch samples analyses and characteristics
Per the GSDP-Reg and the G-GSDP, good distribution and storage practices of pharmaceutical products must ensure the following (Note: Each of the items listed below will not necessarily be found in both sources, which provide overlapping and unique elements):
- Documentation is an essential part of the quality management system and must cover all written procedures, instructions, records, contracts, reports, and data, whether in paper or electronic form
- Documents must be appropriately designed, completed, reviewed, authorized, distributed, and maintained as required
- Documents must be readily available and retrievable for inspection by the TMDA
- The nature, content, and retention of documentation related to distribution and investigations should be retained for at least one (1) year after the expiry date of the product of concern
- Documents must be stored in facilities that safeguard against unauthorized access, modification, damage, deterioration, or loss
- Written procedures must exist for the preparation, review, approval, use, and control of all documents
- Documents must be laid out in an orderly format for easy completion, review, and verification
- Documents should be reviewed regularly and kept up to date; they must use version control mechanisms
- Outdated procedures should be removed from workstations and archived
- Records must be accurate, legible, traceable, attributable, unambiguous, and maintained with backup and restoration procedures in place
- Documents must not be hand-written unless necessary, in which case sufficient space should be provided
- Any alterations to documents must be signed and dated, ensuring the original information remains visible; if applicable, reasons for changes must be recorded
- Documents should be retained for at least five (5) years or as required by regulatory guidelines
- Electronic and physical records must be stored securely, ensuring confidentiality and restricted access
- Electronic storage and signatures may be employed, but access must be restricted, and electronic records must conform to regulatory requirements
- Where applicable, electronic records must be backed up following written procedures; backups should be maintained both within and outside the facility to prevent accidental data loss
- Dealers must maintain comprehensive records of all receipts, storage, issues, and distribution activities. These records must include at minimum: date of receipt or dispatch; Product name (brand and generic); Strength and dosage form; pack size (stock-keeping unit); quantity received or supplied; name and address of the supplier and customer; batch number and corresponding date markings; manufacturing and expiry dates; suitability of the supplier and qualification of customers
- Written documentation must be sufficient to permit tracing and tracking of operations throughout the distribution process
- Records should be created at the time each operation is undertaken
- Internal and external audit reports must be retained along with records of complaints, investigations, and any corrective or preventive actions taken
- Mechanisms must exist for the transfer of information, including quality or regulatory data, between distributors, customers, and the regulatory authority
- Permanent records, written or electronic, must exist for each stored product, specifying recommended storage conditions and any necessary precautions
The G-AppConductCT further requires the sponsor to record and retain destruction operations of IPs. These documents should clearly identify, or allow traceability to, the batches and/or patient numbers involved and the actual quantities destroyed.
See the Data & Records Management section for information about clinical trial-related records retention requirements.
In South Africa, the NHARegMicroLabs refers to a specimen as a “diagnostic specimen,” and defines it as any human or animal material, including excreta, secreta, blood and its components, tissue or tissue fluids, that is to be used for the purpose of diagnosis, but does not include live infected animals. The NHABiol and the G-EthicsHR-ZAF define “human biological materials (HBM)” as material from a human being, including DNA, RNA, blastomeres, polar bodies, cultured cells, embryos, gametes, progenitor stem cells, small tissue biopsies, and growth factors from the same. The G-EthicsHR-ZAF states that blood and blood products are also included pursuant to NHASpecAmend. The NHABloodCells generally refers to substances of human origin as biological substances.
Please refer to the G-EthicsHR-ZAF, the NHABiol, the NHA, the NHABloodCells, the NHATissue, and the NHAStemCell for more specific definitions of selected terms including blood, cultured cells, embryonic tissue, human tissue, plasma, stem cell, and genetic material.
Per the G-EthicsHR-TZA, human biological materials include any substance obtained from a human research participant including, but not limited to, blood, urine, stool, saliva, hair, nail clippings, skin, and microorganisms and other associated bio-products. In Tanzania, specimens are biological materials transferred between researchers/organizations for medical research use only (see TZA-10).
Import/Export
Per the NHA, the MTA-Human, the NHABloodCells, the NHARegMicroLabs, the NHATissue, and the NHAStemCell, a permit must be obtained from the National Department of Health (NDOH) Director General to import or export human biological material (HBM). Both the South African Health Products Regulatory Authority (SAHPRA) approval letter and the NDOH import/export permit must be included with each HBM shipment. See also the Submission Content section for information on completing a clinical trial application. (Note that HBM is referred to as a “biological substance” in the older South African regulations (e.g., the NHABloodCells); this summary will hereinafter use HBM to refer to human biological material, specimens, and biological substances.)
As set forth in the NHA, the NHABloodCells, the NHARegMicroLabs, the NHATissue, and the NHAStemCell, the NDOH Director-General, as delegated by the NDOH Minister, is responsible for establishing regulations related to the import and export of HBM. In addition, only the Minister can authorize an institution or hospital to import or export HBM for research purposes.
In accordance with the NHA, the NHABloodCells, the NHARegMicroLabs, the NHATissue, and the NHAStemCell, the NDOH Director-General reviews and approves all import or export requests by an institution or hospital. These requests must be submitted in writing using the application forms that may be obtained by contacting the NDOH Permit Programme at importexportpermit@health.gov.za. The forms also appear as Annexures 1-6 in the NHABloodCells and Form 1 in the NHARegMicroLabs.
Upon review of the application, the Director-General will issue a permit or certificate authorizing the import or export request if the Director-General is satisfied that the submission meets the NHA, the NHABloodCells, the NHARegMicroLabs, the NHATissue, and the NHAStemCell requirements, as applicable. The permit will contain an expiration date for the approved HBM.
Per the G-EthicsHR-ZAF, sharing HBM and data about HBM must comply with the POPIA and may not occur unless:
- The recipient is in a country that has similar legal protections for processing of personal information
- For situations where the recipient is in a country that does not have an adequate level of protection, prior authorization has been obtained or there is a code of conduct in place
- The data subject has consented specifically to the intended transborder data sharing
- The transfer is necessary in terms of a contract or for the benefit of the data subject
In addition, per the G-EthicsHR-ZAF, ethics committees (ECs) should consider the following during the review process for proposed HBM and HBM data sharing:
- The recipient of such data should have the necessary research approvals to use the data for research purposes
- The recipient should comply with the POPIA requirements, have clear processes to deal with possible data breaches, and must inform the provider and EC should a breach occur
- The recipient must specify the timeframe for storage of the data and its destruction, where relevant
- Any proposed re-use of the data not specified in the protocols should be subject to EC review and approval, as well as approval from the provider
- Intellectual property rights must be specified
- If the HBM and data are shared only for research purposes, such HBM and data cannot be used for commercialization
- The researchers involved in HBM and data sharing must ensure that proper updated records are kept
- Where data alone is shared, a Data Transfer Agreement (DTA) or Data Sharing Agreement (DSA) is necessary
General Import/Export Requirements for HBM
The NHABloodCells states that each HBM to be imported into South Africa must be accompanied by a certificate from the supplier stating that the substance has been exported in terms of the originating country’s applicable laws and regulations.
As per the NHABloodCells and ZAF-7, export permits for HBM may only be issued by the Director-General to a Southern African Development Community (SADC) member state or to a South African citizen, provided that the country’s market requirements have been met. An applicant must also be registered with the Health Professions Council of South Africa (HPCSA) and operating in South Africa in order to apply for a permit to import or export HBM. The applicant must also provide the Director-General with written information on stock levels for this substance along with the export application.
Applicants to whom a permit has been issued must keep a record of the import or export and submit this information using the register forms listed in Annexures 4, 5, and 6 of the NHABloodCells. The forms must be submitted to the Director-General annually before the end of February, for the preceding calendar year.
Import/Export Requirements for Specific HBM Categories
The NHABloodCells provides details on unique application requirements for specific types of HBM as outlined below:
- Import of tissues being used for therapeutic purposes: application must be accompanied by donor health status
- Export of tissues or gametes: application must include written proof that the donated HBM complies with the NHA requirements
- Import or export of placenta tissue, embryonic or fetal tissue, embryonic, fetal or umbilical stem cells: applications will only be approved with the Minister’s written consent
- Import or export of blood or blood products: applications must be accompanied by a national blood transfusion service certificate and test results. If no documentation is included, the applicant must submit a letter to the Director-General explaining the reason. The Director-General will decide whether tests must be conducted, and the Minister is authorized to determine whether the applicant’s institution can be exempted from these requirements.
Material Transfer Agreement
Per the MTA-Human, all the providers and recipients of HBM for use in research or clinical trials under the auspices of ECs must use the “Material Transfer Agreement of Human Biological Materials” in MTA-Human. The agreement must be signed by the research institution’s authorized representative and the EC. The EC’s obligations are to:
- Review and approve research proposals and protocols that require the transfer of human biological materials
- Review and approve the material transfer agreement (MTA) and ensure it adequately safeguards human biological material and ethical requirements
- Review and approve all secondary use research if the material is to be transferred
The EC must be the last party to sign the agreement after all the provisions of MTA-Human have been satisfied.
The G-EthicsHR-ZAF indicates that the MTA covers the transport of HBM between institutions/organizations within the country and cross-border transfers to provide access by the recipient to that material. The MTA should provide guidance on key issues, such as:
- Purpose of the transfer of the HBM
- Obligations of the parties
- Terms and conditions under which HBM may be used
- Whether modifications to the HBM are permissible
- Whether third-party transfers may happen
- What the benefit-sharing arrangements are
- The relevant intellectual property rights
- The indemnity arrangements
Research institutions may tailor the content to suit their individual contexts. Although some MTAs may include clauses governing sharing of data, it is advisable, as part of data management, to enter into separate data sharing agreements to regulate sharing of one (1) or more data sets from the custodian/provider to a third party.
Import/Export
As delineated in the G-EthicsHR-TZA, investigators, sponsors, and collaborators must ascertain that in-country capacity to perform the required investigations/testing is not sufficient for the investigations before considering import of human biological materials outside the country. The only exception to this is when samples are being transferred for external quality assurance purposes. Investigators, sponsors, and collaborators are encouraged to build, develop, or strengthen local capacity for any investigative testing to fulfill the objectives of the proposed research study. All exchanges and transfers (including importation) of biological materials for research purposes requires approval from the National Health Research Ethics Committee (NatHREC).
The G-ResearchClearance requires foreign researchers to identify and affiliate with a locally-recognized institution. The local institution should support foreign partners in permit acquisition, communicating with relevant government offices, and facilitating the material transfer arrangements and access benefit sharing arrangements.
As indicated in TZA-5, when sharing or transferring material and/or data into or outside Tanzania, materials and/or data may be subject to government regulation and import/export control laws that define the conditions under which certain information, technologies, and materials can be transferred or shared. In situations where materials and/or data are shared or transferred from foreign or international investigators to Tanzania, the provider’s country regulations for sharing or transferring materials and/or data will guide the initial process. After sharing and/or transferring material and/or data outside Tanzania, the principal investigator should provide NatHREC with proof of shipment.
Material Transfer Agreement
As delineated in the G-ResearchClearance, all researchers granted Tanzania Commission for Science and Technology (COSTECH) research permits that involve the collection of human data intended to be exported outside Tanzania must submit to COSTECH a signed Material Transfer Agreement (MTA) (TZA-10) and a Data Transfer Agreement (DTA) (TZA-8) between the Tanzanian institution and its foreign counterpart. The MTA and DTA will specify the terms for collecting, storing, managing, transporting, and disposing or returning the materials and data to Tanzania. TZA-5 also requires submittal of the MTA and DTA to the NatHREC during the ethics review. Investigators who wish to share or transfer materials and/or data should complete an MTA or a DTA before any research samples/materials or data are transferred or shared with another institution, laboratory, or researcher. Authorized investigators and signatories from the recipient’s and provider’s institutions must complete the MTA and/or DTA and submit them to NatHREC for certification before any research samples, materials, and/or data is transferred or shared to another institution, laboratory, or researcher.
As delineated in the G-EthicsHR-TZA, when it is necessary to transfer samples for storage abroad, the host institution must negotiate an MTA with the recipient institution. The specific details of the MTA should include, among others, purpose for the transfer/export, clear arrangements for collaboration and benefit sharing, a framework for accessing and sharing data, restrictions to third-party transfer, and annual reports to the host institution and the National Institute for Medical Research (NIMR) on the status of the samples. Applications for permission to exchange or transfer human biological materials must be made to NIMR. The following are the necessary steps for the exchange or transfer of materials for research purposes:
- The research study that involves the exchange or transfer of human biological material must first be registered and approved by the ethics committee (EC) through the established procedures for research approvals in Tanzania
- The applicant must be a legal resident of Tanzania or be affiliated with a local legally recognized institution in Tanzania
- A request for the exchange or transfer of human biological material must be made in writing to the Director General of NIMR
- An MTA and any other document related to the exchange or transfer of human biological material must accompany the request for the exchange or transfer of the material
- The MTA, after review and approval, is signed by the NIMR Director General or a delegate
- After receipt of a signed MTA, the investigator is required to secure an export or import permit from the Tanzania Medicines and Medical Devices Authority (TMDA) to finalize the process that allows the movement of biological samples outside the country or to enter the country
- The investigators must abide by any other requirements that are to be followed to facilitate the exchange or transfer of human biological material
In accordance with the NHA, the NHASpecAmend, the NHABiol, and the MTA-Human, prior to removing or withdrawing any human biological material (HBM) from the body of a living person for research purposes, consent must be obtained from that person in writing, before a competent witness. If the person is a minor, the parent/guardian of that person must provide consent. Furthermore, when withdrawing blood, the NHASpecAmend requires written consent from persons older than 16 years. Per the MTA-Human, the sponsor must obtain the completed informed consent form (ICF) from the donors of HBM and data, and submit it with the project protocol to the ethics committee (EC) for approval. Further, the sponsor must submit the ICF for secondary uses of the material to the EC should the need arise. Secondary use is defined as the use of the materials for health research purposes other than the uses determined in the approved protocol.
Per the G-EthicsHR-ZAF, collection of HBM specifically for research use requires prospective informed consent, usually from the participant. In exceptional circumstances, where a participant is not able to provide informed consent, proxy consent may be permissible. Different consent models may be used depending on the circumstances. Specific (narrow) consent is the most restrictive and permits use of the HBM for the current research study only and excludes consent to storage of leftover HBM for later use and sharing of data or HBM with other researchers, which means that the HBM (including leftover and waste) must be disposed of at the end of the current study. If further use for additional research is wanted, fresh consent must be obtained before disposal occurs.
G-EthicsHR-ZAF states that tiered (differentiated) consent lets the participant provide consent for the current study and to include consent to a small range of additional options if wanted (e.g., to permit storage of their HBM and associated data for specified future research use, or to permit data sharing, or both, etc.). Broad consent is more flexible than tiered consent but still maintains limitations. It lets the participant provide consent for the current study, and to include consent for storage, and for future research use that is within the scope of the current research. This is permitted even if the precise topic of future research is unclear at present. The nature of possible further usage should be described as fully as possible even if the precise topics are unknown; and the consent document must stipulate that further prior ethics review of any new study is necessary, and that permission may be requested to re-contact the person for fresh consent if the future use is outside the scope of the current consent. Certain persons are specially protected: HBM may not be taken from mentally ill or incapacitated persons; HBM that are not naturally replaceable may not be taken from a minor; no gametes may be taken from a minor; and no fetal HBM, except for umbilical cord progenitor cells, may be collected. These restrictions are absolute, which means that research with the categories of person mentioned requires Ministerial permission. Researchers must provide ECs with appropriate evidence that the necessary permission has been obtained.
The G-EthicsHR-ZAF states that the research participant has a right to withdraw consent; however, this right is limited with anonymized HBM and data.
The NHABiol specifically states that when taking HBM samples from a child, where the person is younger than 18 years, Part 3, Section 129 of the ChildrensAct must be followed.
Additionally, the NHABiol requires the following consent for the removal or withdrawal of HBM samples to treat a person with mental illness:
- The mentally ill person’s consent, if capable;
- A court appointed curator, spouse, next of kin, parent or guardian, major child, brother, or sister, partner or associate, if the mentally ill person is incapable of giving consent; and
- The head of the health institution in the case of an emergency
Similarly, the NHA and the NHABiol include consent provisions for the donation of human bodies and the tissue of deceased persons. These documents state that any person who is competent to make a will may donate their body or any specified tissue to be used after death for medical and dental purposes, as long as the person signs the will in the presence of at least two (2) competent witnesses. The person may also give consent to a post-mortem examination of their body for research purposes, and may select an institution or person as the recipient. In the absence of a donation as described above, the individual’s spouse, child over 18 years, parent, guardian, or brother/sister over 18 years may donate the person’s body or any specific tissue to an institution or person for research purposes. Please refer to the NHA and the NHABiol for detailed requirements. (See the Required Elements and Participant Rights sections for additional information on informed consent).
The SA-GCPs observe that many HBM samples are collected during clinical interventions for diagnostic purposes, which means the potential for future use of these samples may be presented. Use of human biological materials and their associated data facilitates research in new technologies, which include genetic and genomic research, and cell and gene therapy (CGT). Sponsors and researchers should, therefore, follow the fundamental ethical principles that underpin all research involving human biological materials and their associated data. Research proposals must address specifically the social value of the research especially in the local context; how consent, privacy, confidentiality will be managed; and the potential effect on families, communities, and other groups. Specific concerns include protection of privacy and whether and how incidental findings are to be communicated to the person from whom the sample originates.
In addition, per the NHATissue, tissue banks are required to develop donor record management systems in which the tissue donor register contains the full identity and relationship of the consenting person. The system will also document tissue banking processes, including the process of obtaining informed written consent.
See the G-EthicsHR-ZAF for additional details on HBM consent, including for databases, storage, and access.
Human Stem Cell Consent Requirements
The NHAStemCell similarly states that authorized stem cell banks must retain a record of the donor’s written informed consent. Further, no person shall use stem cells or its therapeutic research products for educational purposes unless authorized by the National Department of Health (NDOH) and is compliant with the following requirements:
- Has obtained the donor’s informed written consent even in the case of residual tissue, blood, or blood products
- Is certain the donor has donated voluntarily, and it is properly documented
The NHA also indicates that the NDOH Minister may permit research on stem cells and zygotes that are not more than 14 days old on a written application, and if the applicant documents the research for record purposes, and prior consent is obtained from the donor.
Human Genetic and Genome Research Consent Requirements
The G-EthicsHR-ZAF states that the investigator or institution must obtain consent for human genetic research. Researchers must provide detailed information in the protocol for the EC’s ethics review. When assessing the ethical implications of proposed genetic research, ECs must pay attention to multiple considerations, including the anticipated social value of the research, consent, privacy, confidentiality, as well as the potential effect of the research findings on families, communities, and other social groupings. Because of the types of information that genetic research may reveal, including the range of consequences of this information for participants and their relatives, ECs should consider developing a plan to manage this kind of information. Often, follow-up clinical testing or counselling may be recommended. The proposed plan to manage the information gathered from genetic research should indicate the clinical relevance of the study findings, the implications of the study findings for both participants and those involved in the study, as well as whether and how these findings will be disseminated. This plan must be explained to potential participants.
Per the G-EthicsHR-ZAF, regarding genetic and genome research, specific elements should be incorporated into the separate consent process in addition to the usual information for appropriate informed consent for research participation. Common features of genetic and genomic research that must be explained include what genetic or genomic research means, that indefinite storage and future use and sharing of HBM and derived data is requested, that there are ongoing privacy vulnerabilities for participants as well as for third parties, and that there may be social harms. See the G-EthicsHR-ZAF for detailed requirements.
Waiver of Consent
Per the G-EthicsHR-ZAF, a waiver of consent might be granted for research using archived HBM in circumstances where the HBM is anonymous and the HBM data will also be anonymous and aggregated. However, waivers relating to genetic and genomic research should be approached cautiously, since re-identification of the original source of the HBM may be technically possible despite anonymity of HBM.
In accordance with the G-AppConductCT, prior to collecting, storing, or using a research participant’s biological specimen(s), informed consent must be obtained, including for any proposed archiving of specimens for future research. Per the G-EthicsHR-TZA, if it is anticipated that collected human biological materials may be used for other research purposes in the future, the informed consent should include information to participants about future intended use. The information should clearly state that the collected materials will be stored for possible future research studies. Research participants should be informed on measures to protect confidentiality and policies that will govern use of the samples in future research studies. After explaining the need to store the samples, the research study participant should be permitted to choose whether their samples should or should not be stored and/or used for future studies. See the G-EthicsHR-TZA for additional information on the storage and future use of biological samples.
