Liberia Medicines and Health Products Regulatory Authority
As per the LMHRA-Act, the LibCTReg, and the G-LibClinTrial, the Liberia Medicines and Health Products Regulatory Authority (LMHRA) is the regulatory authority responsible for clinical trial approvals, oversight, and inspections. According to the LMHRA-Act, the LMHRA operates as an autonomous government agency that reports to the President of the Republic of Liberia. In addition to its role in authorizing clinical trials, the LMHRA-Act indicates that the LMHRA’s responsibilities also include drug and health care product registration, inspections, import/export control, licensing, quality control, advertising and promotion, and pharmacovigilance and post-marketing surveillance.
Per LBR-30, the Clinical Trials Unit within LMHRA’s Pharmacovigilance & Clinical Trials Department is responsible for coordinating all aspects of clinical trials in Liberia including:
- Receiving and assessing all clinical trial applications submitted to the LMHRA
- Conducting good clinical practice (GCP) inspections of trial sites and GCP training for inspectors and the study team to ensure compliance that is in line with LMHRA regulatory requirements and international best practices
- Reviewing all reports from clinical trial sites and advising management on appropriate regulatory actions
- Investigating the conduct of clinical trials
- Suspending or stopping clinical trials (depending on the magnitude of the offense)
- Serving as secretariat for the Scientific Advisory Committee (SAC) on clinical trials
- Reviewing importation permits for investigational products (IPs) that are required for the conduct of clinical trials
- Conducting pre-submission meetings to discuss issues related to application processes
- Reviewing all reports (safety reports, quarterly reports, Serious Adverse Events (SAE) reports and final or close-out reports) from clinical trial studies conducted
Per the LibCTReg, the LMHRA can establish advisory committees for the review of clinical trial applications and for post-approval safety and compliance issues, if needed, and especially in the event of new/emerging technologies. According to LBR-29, the LMHRA has established an SAC to provide technical support to review clinical trial applications.

Overview
In accordance with the LMHRA-Act, the LibCTReg, and the G-LibClinTrial, the Liberia Medicines and Health Products Regulatory Authority (LMHRA) is responsible for reviewing, evaluating, and approving applications for clinical trials using registered or unregistered investigational products (IPs). According to the G-LibClinTrial, proposed clinical trials of registered medicines may include changes to indications, new methods of administration, or new combinations, etc. The G-LibClinTrial specifies that the scope of the LMHRA’s assessment includes all clinical trials (Phases I-IV). In addition, per the LibCTReg and the G-LibClinTrial, the National Research Ethics Board of Liberia (NREB) and LMHRA reviews may be conducted in parallel. However, the G-LibClinTrial and the G-NREB specify that the LMHRA will only issue final approval once NREB (ethics committee (EC)) approval is obtained.
Clinical Trial Review Process
According to LBR-30, the LMHRA’s Clinical Trials Unit within the Pharmacovigilance & Clinical Trials Department is responsible for coordinating all clinical trial activities. According to LBR-29, the LMHRA has established a Scientific Advisory Committee (SAC) to review clinical trial applications.
Per the G-LibClinTrial, the LMHRA will only process an application upon receipt of a completed application and the prescribed fees. Upon receipt, the LMHRA screens the clinical trial application package for completeness and must inform the applicant in writing about the validity of the application or the formal grounds for non-acceptance of the application. After validating the application package is complete, the LMHRA conducts a scientific assessment of the application.
During the clinical trial scientific assessment process, the LibCTReg and G-LibClinTrial also explain that relevant clinical trial decisions, reports, or information from other national regulatory authorities or regional and international bodies can be recognized or used by the LMHRA. The LibCTReg further specifies that the scope/extent of utilization of relevant clinical trial decisions, reports, or information from other national regulatory authorities or regional and international bodies will be at the sole discretion of the LMHRA. In such instances, business and company secrets must remain confidential.
The LibCTReg also states that the LMHRA must inform the NREB if it is in possession of information bearing on other clinical trials which is of significance to the board's assessment of the clinical trial on which it is to issue an expert opinion; this applies especially to information on aborted or otherwise prematurely discontinued investigations. In such instances, business and company secrets must remain confidential. Also, the LMHRA must ensure that the list of approved and rejected clinical trial applications as well as summary of evaluation reports and status of approved clinical trials are publicly available and periodically updated.
Per G-LibClinTrial, all applications must be evaluated with the same set of criteria based on up-to-date scientific knowledge and ethics standards, regardless of the applicant. The LMHRA may also request additional documents or changes through a query letter. Once a query has been raised and issued to the applicant, the process stops when the LMHRA receives a written response to the query. If the LMHRA requires changes to the application, the applicant must modify the application within an established timeline, or it will be rejected.
As indicated in the G-LibClinTrial, the LMHRA must issue a clinical trial certificate indicating the LMHRA clinical trial number to the applicant upon application approval. The clinical trial certificate may contain conditions required by the LMHRA with respect to the conduct or reporting of the trial. If the application is rejected, the applicant can submit a written appeal to the LMHRA’s Managing Director. Moreover, the information provided in a clinical trial application must not be disclosed by the LMHRA to a third party except with the written consent of the applicant or in accordance with the directive of the LMHRA Board of Directors.
Per the LibCTReg and the G-LibClinTrial, under certain circumstances, the LMHRA may accept an expedited application and review process for clinical trials (e.g., epidemics or other urgent public health interests requiring fast use of new medicines or health products and/or fast gathering of health product information). The LibCTReg also notes that in the case of emergency situations, the LMHRA may also make exemptions to the documentation requirements for the submission of clinical trial applications. Refer to 2.3 of the G-LibClinTrial for additional information on how to submit an expedited clinical trial application package. In the case of trials involving human participants, per the G-LibClinTrial, the applicant must provide proof of current, relevant, and appropriate study insurance for all participants or professional indemnity insurance for investigators as part of the application submission package to be sent to the LMHRA.
As delineated in the LibCTReg, any amendments to approved clinical trial documentation, trial arrangements, and the IPs referenced in the application must be classified and processed as determined by the LMHRA in the corresponding guidelines. The G-LibClinTrial explains that depending on the nature of the change, trial amendments are regarded as substantial or non-substantial/minor amendments. Amendments to a clinical trial are regarded as “substantial” when they are likely to have significant impact on the safety or physical or mental integrity of the trial participants and/or the scientific value of the trial. Any substantial amendments to the clinical trial protocol, clinical trial arrangements, or the IP or related product deemed to be an amendment must be approved by the LMHRA and the NREB before such amendments are carried out. Written NREB approval is also required before the LMHRA can reach a decision on an amendment. The LMHRA should respond within 20 calendar days upon receipt of the NREB’s written decision. The LMRHA may reject or accept the changes, or recommend a revision of the sponsor’s classification.
Per the G-LibClinTrial, non-substantial/minor amendments, by comparison, can be implemented immediately by the sponsor and should always be documented and notified to the LMHRA and the NREB. However, in order to allow the LMHRA to exercise its clinical trial oversight function, the sponsor should ensure that the LMRHA is aware of a non-substantial amendment(s) as soon as possible. For example, progress reports including safety data as well as annual updates of the investigator's brochure (IB) are not considered amendments per se, and therefore, do not have to be notified as substantial amendments to the LMHRA. However, the sponsor has to verify whether the data presented requires a change to the documentation submitted with the request for clinical trial authorization. If this amendment is substantial, the rules for notification of substantial amendments apply to these changes. See the G-LibClinTrial for additional amendment requirements. See the Submission Process section for amendment submission requirements.
Per the LibCTReg, the LMHRA’s written approval of a clinical trial with IPs involving human participants is based on the conclusion that the anticipated therapeutic and public benefits justify the risk and may be continued only if compliance with this requirement is permanently monitored. An LMHRA authorization may only be refused if:
- The documents submitted are incomplete up to the expiration of an appropriate deadline given to the applicant for their supplementation
- The documents submitted, especially the data on the IP(s) and the trial protocol including the investigator's brochure (IB), do not comply with the current state of scientific knowledge, and especially, the clinical trial is unsuitable for providing proof of IP(s) safety or efficacy, or
- In the case of trials involving human participants, the documentation requirements (see Section 1 (4) of LibCTReg), particularly insurance coverage for trial participants, are not fulfilled
- The LMHRA is in possession of findings which indicate that the testing facility is not suitable to conduct the clinical trial
- The LMHRA is of the opinion that the number of clinical trial participants to be recruited in the trial is not scientifically justified, or
- The requirements provided for in the general conditions and special preconditions for conducting a clinical trial (see Chapter II (Sections 1-2) of LibCTReg) are no longer fulfilled
The LibCTReg indicates that in a clinical trial of an IP consisting of a genetically modified organism, consisting of a combination of genetically modified organisms, or containing such organisms, unjustifiable harmful effects on the health of third persons and the environment are not to be expected when the trial is conducted according to the state of scientific knowledge in relation to the trial’s purpose.
(See the Submission Process and Submission Content sections for detailed submission requirements and the Timeline of Review section for additional LMHRA timeline information.)
The LibCTReg further explains that a clinical trial authorization must be suspended by the LMHRA for a limited period of time if at least one (1) of the following is true:
- It becomes known that one (1) of the grounds for refusal previously indicated existed at the time the trial authorization was issued (see also Chapter II (Section 5 (3)) of LibCTReg)
- The conditions surrounding the clinical trial do not correspond to the information contained in the authorization application
- The facts presented give reason to doubt the safety or the scientific basis of the clinical trial
Per the LibCTReg, the LMHRA must withdraw a clinical trial authorization when scientific justification for resuming the trial is not provided to address the reasons previously indicated for suspension. The LMHRA must also immediately inform the NREB through a written communication stating the grounds for its action. Before a decision is taken, the applicant must be allowed a deadline of 10 working days to submit a statement, unless the LMHRA orders the immediate interruption of the clinical trial. The lodging of an objection and an action to rescind the withdrawal or the order to suspend the authorization should not have a suspensive effect. If the authorization to conduct a clinical trial is withdrawn or suspended, the clinical trial may not be continued. Also, if the LMHRA, in the context of its activities, becomes aware of facts which justify the assumption that one (1) or more of the investigators or the sponsor or the sponsor’s representative no longer fulfills their obligations with regard to the proper conduct of the clinical trial, the LMHRA must immediately inform this individual(s) and must order remedial measures to be taken by the individual(s).
Pursuant to Part VIII of the LMHRA-Act, the LibCTReg states that any person(s), institution(s), corporate entity(ies), their designees, or legal representatives who violates the clinical trial authorization procedures, the serious adverse event notification requirements, and/or the suspension/withdrawal provisions delineated in the LibCTReg will be liable to pay administrative fines. See the LibCTReg for details.
Inspection
As stated in the LibCTReg, the LMHRA should inspect a clinical trial to ensure that the general public is adequately protected against the adverse event risks related to a clinical trial with IP(s); and, to confirm that the PI and the sponsor, including the sponsor’s representatives, are strictly adhering to the specific and general conditions to which the trial was authorized. The G-LibClinTrial also indicates that the LMHRA may inspect clinical trial sites and/or the sponsor's/contract research organization (CRO)’s premises and/or the manufacturer’s premises to ensure that the clinical trials comply with good clinical practice (GCP) provisions before, during, or after the trial is conducted.
Per the LibCTReg and the G-LibClinTrial, NREB representatives may accompany the LMHRA during clinical trial site inspections, or, per the LibCTReg, they may choose to do the inspections independently. The G-LibClinTrial also notes that the LMHRA may include other relevant regulatory authorities in the inspection. The PI and/or the sponsor/CRO and/or the manufacturer must be notified in writing of the inspection unless the LMHRA has reasonable cause to believe that the approved protocol is being violated. In this case, an unannounced inspection may be conducted. Following these inspections, the LMHRA must prepare an inspection report, and the report will be made available to the PI and/or sponsor while safeguarding the confidential aspects. The report may also be made available to the NREB and other regulatory authorities upon their request.
Additionally, the LibCTReg specifies that the LMHRA may also:
- Request additional information
- Inspect any resources that are deemed by the LMHRA to be related to the clinical trial and that may be located at the trial site, the sponsor´s and/or CRO’s facilities, or other establishments deemed appropriate by the LMHRA
- Suspend or stop a clinical
- Withdraw the authorization to conduct a clinical trial, if the LMHRA is of the opinion that the safety of the trial participants may be compromised, that the scientific reasons for conducting the trial have changed, or if the integrity of the data is compromised
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
Per the G-ACRE-IRB and the G-NREB, all research involving human participants should be reviewed by an ethics committee (EC). According to the NatResHlthPlcy, Liberia has two (2) ethics committees (ECs): the National Research Ethics Board of Liberia (NREB) and the Atlantic Center for Research and Evaluation Institutional Review Board (ACRE IRB) (formerly known as the University of Liberia-Pacific Institute for Research and Evaluation Institutional Review Board (UL-PIRE-IRB)).
National Research Ethics Board of Liberia
As explained in the G-NREB, the NREB is an advisory institution that reports to the Ministry of Health (MoH), and its members are appointed by the Minister of Health. According to LBR-38, only the NREB has the sole responsibility to review all clinical trial protocols. The G-NREB states that the board ensures all research related protocols within and outside of Liberia are in compliance with internationally recognized ethical standards (including the Belmont Report (LBR-11), the Declaration of Helsinki (LBR-27), the International Council for Harmonisation’s Guideline for Good Clinical Practice E6(R2) (LBR-8), and the Council for International Organizations of Medical Sciences (CIOMS’) International Ethical Guidelines for Health-related Research Involving Humans (LBR-2)), as well as Liberia’s applicable regulations and guidelines. In addition, per the G-NREB and LBR-12, the NREB is responsible for reviewing research proposals involving human participants to assess their compliance with ethical principles, regulatory requirements, and international guidelines, and for approving research protocols that meet ethical standards and providing recommendations for addressing any ethical concerns.
Per the NatResHlthPlcy the G-NREB, and LBR-12, the NREB is also responsible for the following (Note: Each of the items listed below will not necessarily be found in all sources, which provide overlapping and unique elements):
- Ensuring that researchers obtain informed consent from participants and protect their rights, privacy, and confidentiality
- Evaluating the potential risks and benefits of research projects and ensure that they are justified and minimized
- Developing and disseminating policies, guidelines, and standards for ethical conduct in research
- Providing guidance and support to researchers, research institutions, and ECs on ethical issues related to research involving human participants
- Fostering awareness and understanding of ethical principles and regulatory requirements among stakeholders in the research community
- Conducting training programs, workshops, and seminars to educate researchers, EC members, and other stakeholders on ethical principles and best practices in research ethics
- Building the capacity of research institutions and ECs to effectively review and oversee research involving human participants
- Promoting a culture of ethical conduct and responsible research practices within the research community
- Monitoring compliance with approved research protocols and ethical standards throughout the duration of research projects
- Conducting periodic reviews or audits of research activities to ensure adherence to ethical principles and regulatory requirements
- Investigating and addressing any allegations of research misconduct or breaches of ethical standards
- Establishing guidelines for the review of research for health protocols for use by other review boards
- Giving advice on ethical research issues to the MoH and related government ministries and agencies
- Engaging with the public, policymakers, and other stakeholders to raise awareness of ethical issues in research and foster dialogue on ethical considerations
- Advocating for the protection of research participants’ rights and the promotion of ethical conduct in research at the national and international levels
- Collaborating with relevant government agencies, institutions, and organizations to advance the ethical governance of research
- Establishing and maintaining a repository of all protocols reviewed in the country along with finished research/study reports
Atlantic Center for Research and Evaluation Institutional Review Board
As noted in the G-ACRE-IRB, the ACRE IRB is mandated by the Board of Directors of the ACRE Africa Center. According to LBR-28, the ACRE IRB has the expertise to review clinical research, and some members of the ACRE IRB also serve on the NREB and provide expertise in the review of clinical trial protocols. However, due to a Memorandum of Understanding (MOU) between the NREB and the ACRE IRB in 2022, the ACRE IRB does not review and approve clinical trial protocols. All clinical research protocols submitted to the ACRE IRB are referred to the NREB.
Ethics Committee Composition
National Research Ethics Board of Liberia
According to the G-NREB, the NREB is composed of 21 members who jointly represent a diverse community with a range of expertise. The G-NREB notes that the majority of the board members are clinicians, scientists, and national subject matter experts. Per LBR-18, the NREB board typically consists of experts in various fields related to research ethics, such as medicine, public health, social sciences, ethics, law, and community representatives. Board members may include researchers, ethicists, healthcare professionals, legal experts, and representatives from government agencies and civil society organizations. LBR-38 further specifies that the NREB membership includes, but is not limited to, a sociologist, an infectious disease scientist, a biologist, a lawyer, a pharmacist, an epidemiologist, a statistician, a bioethicist, a mental health specialist, a health system strengthening specialist, a religious elder, community elders, surgeons, clinicians, and public health specialists.
In addition, per LBR-18, although the NREB organization structure may vary based on its specific mandate, size, and operational requirements, the board typically consists of a chairperson/executive director, a secretariat or administrative staff, ethics review committees/panels, and advisory groups that may provide specialized expertise or support for specific activities or initiatives.
Atlantic Center for Research and Evaluation Institutional Review Board
As specified in the G-ACRE-IRB, the ACRE IRB members (full, regular, and ad-hoc) must be recommended by the ACRE IRB Chair and appointed by the ACRE Board of Directors. The ACRE IRB must be comprised of 12 members with the qualifications and experience, individually and collectively, to review and evaluate the scientific, medical, and ethical aspects of research protocol submissions. The membership must include both scientists and non-scientists from diverse backgrounds to undertake an impartial and adequate review of research proposals. The ACRE IRB membership must include the following:
- Scientists (including, but not limited to, professionals in natural science, social science, and behavioral science)
- Non-scientists (health practitioners, legal experts representing the community, and civil society)
In addition, the ACRE IRB must ensure social inclusivity and gender sensitivity in its membership and recruitment of ad-hoc reviewers. There must be adequate representation by age, gender, community, etc., on the board to safeguard the interests and welfare of all segments of society. ACRE IRB members must be drawn from both public and private institutions within the country.
Terms of Reference, Review Procedures, and Meeting Schedule
National Research Ethics Board of Liberia
Pursuant to the G-NREB, the NREB follows standard operating procedures (SOPs) as well as relevant ethical guidelines and regulations to ensure compliance with research ethics principles and to uphold societal interests. The NREB may seek subject matter expert opinions regarding specific research protocols and/or issues, as long as the experts have no conflict of interest, including participation in the research, financial interest in the outcome, and/or involvement in competing research, among other reasons. NREB members should meet bi-monthly for regular meetings and adhere to the board’s threshold requirement to review a minimum of three (3) complete applications at each meeting. When applicable, the NREB director may also convene ad-hoc meetings. All complete applications submitted by the deadline must be reviewed at the next regularly scheduled meeting if the number of applications meet the threshold. Members are encouraged to attend all meetings and the quorum required for voting is two-thirds of the NREB membership. Members who cannot attend a meeting due to unforeseen reasons must inform the NREB director two (2) weeks prior to the scheduled meeting. If unable to attend, members must also advise the NREB director regarding their views or concerns on specific agenda items one (1) week prior to a scheduled meeting. Meeting agendas and research protocols should be distributed to members no later than three (3) weeks before a regular meeting. Refer to the G-NREB and LBR-12 for detailed committee requirements.
Atlantic Center for Research and Evaluation Institutional Review Board
As delineated in the G-ACRE-IRB, the ACRE IRB Chair must be the head and chief spokesperson of the board and must conduct meetings in accordance with the policies, regulations, and timetable approved by the board. ACRE IRB members must be appointed initially for a term of three (3) years, which must be renewable and is subject to the ACRE IRB Board of Directors’ decision. To maintain continuity in ACRE IRB operations, at least one-third of the membership must be retained at any given time. The outgoing Chair must be an ex-officio member of the incoming ACRE IRB. ACRE IRB members and consultant reviewers must be provided with all relevant SOPs by the Secretariat to guide in the review process of all submitted protocols. ACRE IRB members are required to review, discuss, and consider protocols submitted to the board for evaluation to safeguard the rights, safety, and well-being of study participants; review progress reports and monitor ongoing research studies appropriately; evaluate final reports and outcomes; maintain absolute confidentiality in all document deliberations at board meetings; state conflicts of interest, where applicable; and participate during deliberations. Members with a conflict of interest will recuse themselves from the review of submissions with which they have a conflict, except to answer specific questions posed by the board. Additionally, per LBR-28, ACRE IRB reviews are conducted virtually via the Zoom platform.
The ACRE IRB must convene a meeting every month or when deemed necessary. The Chair, or a delegated board member, must call the meeting to order, provided there is a quorum. If there is no quorum, the meeting must be rescheduled. A quorum must be greater than 50% of the voting board members at any given event. A quorum must consist of regular and/or alternate board members (persons formally selected by the board to substitute for regular members who are unavailable ), and it must include at least one (1) member whose primary background is science related, and one (1) member whose primary background is not science related. Special/independent consultants cannot be used to establish a quorum. Members who are recused from the review of a protocol cannot be used to establish a quorum. A simple majority vote of ACRE IRB members in attendance is required for a protocol to be approved.
The ACRE IRB Chair may invite individuals with competence in special areas to assist in the review of issues that require expertise beyond or in addition to that available on the board. These individuals will be required to sign a confidentiality agreement before they review a protocol or attend a board protocol discussion, however, they are not permitted to vote. The consultant will provide the Chair with a written report to be shared with all reviewers summarizing relevant information.
Refer to the G-ACRE-IRB for detailed information on ACRE IRB administrative processes.
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
According to the G-ACRE-IRB and the G-NREB, the primary scope of information assessed by ethics committees (ECs) in Liberia relates to maintaining and protecting the dignity and rights of research participants and ensuring their safety throughout their participation in a clinical trial. According to the NatResHlthPlcy, Liberia has two (2) ECs: the National Research Ethics Board of Liberia (NREB) and the Atlantic Center for Research and Evaluation Institutional Review Board (ACRE IRB) (formerly the University of Liberia-Pacific Institute for Research and Evaluation Institutional Review Board (UL-PIRE-IRB)).
The G-ACRE-IRB and the G-NREB also state that the ECs are responsible for ensuring independent, timely, and competent reviews of all ethical aspects of the clinical trial protocol. The ECs must also act in the interests of the potential research participants and the communities involved by evaluating the possible risks and expected benefits to participants, and they must verify the adequacy of confidentiality and privacy safeguards. As per the G-ACRE-IRB, the ACRE IRB must pay special attention to reviewing informed consent and protecting the welfare of certain classes of participants deemed to be vulnerable, including children.
See the G-ACRE-IRB and the G-NREB for detailed ethical review guidelines.
Role in Clinical Trial Approval Process
As per the LibCTReg and the G-LibClinTrial, the Liberia Medicines and Health Products Regulatory Authority (LMHRA) and the NREB must approve a clinical trial application prior to the sponsor or the representative initiating the clinical trial. Per the LibCTReg and the G-LibClinTrial, the NREB and LMHRA reviews may be conducted in parallel. However, the G-LibClinTrial and the G-NREB specify that the LMHRA will only issue final approval once NREB approval is obtained. In addition, per the LibCTReg and the G-LibClinTrial, any substantial amendment to the approved clinical trial research protocol must be approved by the LMHRA and the NREB before such amendments are carried out.
Additionally, per the LibCTReg, the LMHRA must inform the NREB if it is in possession of information bearing on other clinical trials which is of significance to the board's assessment of the clinical trial on which it is to issue an expert opinion; this applies especially to information on aborted or otherwise prematurely discontinued investigations. In such instances, business and company secrets must remain confidential.
National Research Ethics Board of Liberia
Per the G-LibClinTrial and the G-NREB, ethical clearance by the NREB is required as part of the LMHRA clinical trial approval process. As per the G-NREB, a protocol will be reviewed if the number of submitted protocols meets the board’s threshold requirement to review a minimum of three (3) complete applications at each meeting.
As delineated in the LibCTReg, the NREB provides its opinion on the application for a clinical trial in line with its written standard operating procedures (SOPs). According to LBR-20, upon receiving the research proposals, the NREB conducts a preliminary screening to ensure that all required documents and information are included and that the proposals meet the submission requirements. Incomplete or insufficient proposals may be returned to researchers with instructions for revisions or additional information. An ethics review committee/panel composed of experts in relevant fields, such as medicine, public health, ethics, law, and community representatives is then assigned by the NREB, and the committee members review the proposals independently or collectively, depending on the complexity of the research and the availability of resources. The ethics review committee/panel thoroughly evaluates each research proposal based on established ethical review criteria.
Per LBR-31, the NREB follows established ethical review criteria to evaluate research proposals to help ensure that research studies adhere to ethical principles and protect the rights, welfare, and dignity of research participants. The ethical criteria delineated in LBR-31 include informed consent, beneficence, justice, privacy and confidentiality, respect for participants’ rights and dignity, scientific validity and integrity, and compliance with regulatory requirements. See LBR-31 for details.
Per LBR-20, the committee members also assess the ethical implications of the proposed research, including the risks and benefits to participants, the adequacy of the informed consent process, the protection of vulnerable populations, and the equitable distribution of research burdens and benefits. The review process may involve discussions, debates, and deliberations among committee members to reach consensus on the ethical acceptability of the research proposals. See also LBR-23 for additional EC review guidelines.
LBR-20 further explains that the NREB communicates the outcomes of the ethical review process to researchers, including decisions on approval, conditional approval pending revisions, or rejection. Researchers receive feedback and recommendations from the EC to address any ethical concerns raised during the review process and may be required to make revisions to their proposals, provide additional information, or address specific ethical issues before final approval is granted. The LibCTReg also notes that a written permission from the NREB may only be refused if the documents submitted are incomplete up to the expiration of an appropriate deadline given to the applicant for their supplementation; the documents submitted, including the trial protocol, the investigator’s brochure, the modalities for selecting trial participants, and informed consent/assent, do not correspond to the current state of scientific knowledge, and especially, the clinical trial is unsuitable for providing IP(s) proof of safety or efficacy, or; the applicable requirements specified in the general conditions for conducting clinical trials (see Chapter II (Section 1) of LibCTReg) are not fulfilled.
Per the G-NREB, a principal investigator (PI) will be contacted by written communication (letter or email) if the NREB determines that additional materials are required to complete its review. PIs may also be asked to be available for presentations and/or contacted during the meetings. The G-NREB also explains that the NREB should notify PIs in writing of its decision within two (2) weeks following a board meeting, where applicable, following a complete review of the protocols. The NREB will also communicate its decisions to the NREB Secretariat. An approval expiration date is not specified. Pursuant to the G-NREB, PIs may also re-submit previously considered protocols, which will require a full NREB review. Per LBR-20, once all the ethical requirements have been met, the NREB grants final approval for the research proposals to proceed.
As indicated in the G-NREB, for continuing review submissions, PIs must submit review reports to the NREB Secretariat at least eight (8) weeks prior to the approved protocol’s expiration. If the NREB has not reviewed and approved a study’s request by the current expiration date, study activities should cease until the board determines whether continuing the research is in the best interest of all previously enrolled participants. The NREB will also review continuing review submissions prior to the expected expiration date of NREB approval for requests to extend the ethical approval to continue implementation of the research project. See LBR-6 for the NREB Continuing Review Form. See the Progress Reporting section for additional information on continuing review.
Additionally, per LibCTReg, the NREB’s written permission must be withdrawn if the NREB subsequently becomes aware that grounds for a refusal as referred to in the clinical trial authorization procedures (see Chapter II (Section 5 (1)) of LibCTReg) existed at the time the authorization was issued. The authorization must be withdrawn if the NREB becomes aware of the fact that subsequently at least one (1) of the following is true:
- Requirements regarding the suitability of the investigator, the investigator’s deputy, or the trial site are no longer fulfilled
- Trial participants are no longer properly insured or the prerequisites for an exception to the insurance obligation no longer exist
- Modalities for selecting trial participants no longer correspond to the current state of medical knowledge and, especially, the clinical trial is unsuitable for providing proof of the IP(s) safety or efficacy
- Prerequisites for the inclusion of persons pursuant to the general conditions and special preconditions for conducting a clinical trial (see Chapter II (Sections 1-2) of LibCTReg) are no longer fulfilled. The NREB shall inform the LMHRA through a written communication
For protocol amendments, per the G-NREB, the NREB must review and approve any protocol amendments prior to implementation. The NREB secretariat must first consult with the NREB Chair to determine the type of review required (full board review or expedited due to risk). Protocols that pose no or minimal risk to participants, have no formal informed consent process, or are subject to NREB continuing review, may be considered exempt and may qualify for expedited review. Refer to the G-NREB for detailed information on the decision types and various review processes the NREB uses to consider protocol submissions.
Additionally, the G-NREB explains that as a condition of research protocol approval, the NREB requires the PI to provide regular updates to the Secretariat from the date of approval. LBR-20 also notes that researchers are required to report any significant deviations from the approved protocols or ethical concerns that arise during the course of the research to the NREB for review and guidance. The NREB may also provide ongoing monitoring and oversight to ensure continued compliance with ethical standards and regulatory requirements. The G-NREB specifies that the NREB must conduct site visits at appropriate intervals. In certain cases, the site visits may be unannounced to ensure the integrity of the study.
Reviews During Public Health Emergencies
As delineated in the G-CTEmergncy, in the event a public health emergency is declared in Liberia or a neighboring country by the World Health Organization (WHO), the Ministry of Health (MoH), or the National Public Health Institute of Liberia (NPHIL), the NREB will expedite the initiation of research and many processes (i.e., drafting documents, translations, and obtaining approvals) will occur in parallel, rather than sequentially, as is typical during non-emergency situations.
Per the G-CTEmergncy, in addition to the NREB review form (if applicable), the following checklist will be included to streamline fast-tracking of epidemic-related research:
- Identify the research as epidemic or outbreak-related to facilitate fast-tracking
- Specify whether prior research data on the disease exists, referencing relevant local and international studies
- Ensure the inclusion of at least one (1) (preferably two (2)) PIs or co-PIs from the country where the research and review take place
- Provide qualifications of key investigators, including details of their previous experience with outbreak-relevant research
- Indicate if the protocol is part of a multicenter trial. If so, describe the status of ethics approval for the master protocol or the ethics approval from the sponsoring country
The G-CTEmergncy indicates that the NREB will also use the following guidelines to ensure compliance during health emergencies:
- Establish surge capacity for reviews and systems for virtual discussions (via platforms like Zoom)
- Identify core members who will handle the majority of the review burden, providing specialized training in outbreak-related research review to ensure high standards without compromising ethical considerations. Additional members can be called upon as demand increases
- The Director will alert members and determine whether they are available for emergency review
- Identify subject experts (technical and ethical) within the country and abroad who are willing to serve as ad hoc or co-opted members during outbreaks, anticipating the need to review multiple studies in a short time
- Establish a quorum consisting of one-third of NREB members, including pre-identified subject matter experts. If a pre-identified member submits their review but cannot attend the meeting, the member will still count towards the quorum
The G-CTEmergncy further states that revised SOPs will be circulated to all review committee members. Meetings may be virtual or electronic to reduce health risks during highly infectious outbreaks (e.g., COVID-19, Ebola). Protocols should be submitted electronically for efficiency, with hard copies to follow if mandatory. PIs must inform the NREB as early as possible about their intent to submit a high-level overview of their research (e.g., trial of a new medicine or vaccine, observational study, or survey) to prepare the committee for forthcoming protocols. Face-to-face meetings with PIs are not mandatory and may be conducted electronically or virtually if necessary. Also, protocols will be sent to reviewers within 48 hours of submission. Reviewers should complete their reviews within five (5) days during an outbreak. The PI should receive consolidated reviews with suggestions or approval within 10 working days, and should respond to the review within 48 hours. The director of the NREB secretariat will be the primary contact for communication with PIs, and all communications will be documented and archived for future reference.
Atlantic Center for Research and Evaluation Institutional Review Board
Per G-ACRE-IRB, the ACRE IRB’s purpose is to review and certify the ethical acceptability of all research involving human participants conducted in Liberia. However, per LBR-28, due to a Memorandum of Understanding (MOU) between the NREB and the ACRE IRB in 2022, the ACRE IRB does not review and approve clinical trial protocols. All clinical trial protocols submitted to the ACRE IRB are referred to the NREB.
Per G-ACRE-IRB, all studies submitted to the ACRE must be approved by the ACRE IRB. This includes all studies conducted by ACRE investigators as well as all research conducted by outside investigators or students and faculty of universities in Liberia. The G-ACRE-IRB is intended to ensure quality and consistency in the ACRE IRB’s review of social, behavioral, clinical, and biomedical research protocols that comply with the Council for International Organizations of Medical Sciences (CIOMS’) International Ethical Guidelines for Health-related Research Involving Humans (LBR-2) and the national ethical guidelines for research on human participants.
According to G-ACRE-IRB, on receipt of a proposal for review, the ACRE IRB Secretariat will preliminarily assess the completeness of the submission. If the submission is incomplete, the Secretariat will inform the PI accordingly and request the additional materials. Once the submission is deemed complete, the Secretariat will notify the PI and distribute the materials to the assigned ACRE IRB members. Exempt studies will be reviewed by all board members; expedited studies will be reviewed by all board members; full review studies will be sent to the entire ACRE IRB membership for review. An expedited study is defined as one which does not require review by a convened ACRE IRB quorum because it has been determined that participants are subject to low risk. Additional information about the various review types can be found in the G-ACRE-IRB. The PI must check the level at which the protocol will be reviewed and confirm the required documents before submitting it for review. Please refer to the G-ACRE-IRB for additional information on the administrative processes relating to proposal submission.
As specified in the G-ACRE-IRB, the ACRE IRB approval will commence on the day the study is approved and will expire within a defined time period based on the risk assessment and regulations. If specific conditions are stipulated in the approval letter, those conditions must be met by the designated date or approval may be withdrawn.
The G-ACRE-IRB also states that the ACRE IRB must review and approve any protocol amendments prior to those changes being implemented. The protocol submission is reviewed either via expedited procedures (for minor changes) or via full ACRE IRB review (for all other changes). The criteria for approval are the same as for initial review. In addition, the ACRE IRB has a continuing responsibility to monitor the approved trial(s) to ensure ethical compliance throughout the study duration. A continuing review is conducted to review progress of an ongoing study, and not just changes made in the study, in order to ensure continued protection of the rights and welfare of research participants. Refer to the G-ACRE-IRB for protocol amendment and continuing review documentation submission and procedural requirements.
Additionally, per the G-ACRE-IRB, a protocol may be selected to undergo post-approval monitoring due to reported complaints and/or requests by the convened EC. Other reasons for post-approval monitoring may include:
- From continuing review or reports from other sources, it is revealed that material changes may have occurred without ACRE IRB approval
- Where an investigator conducting a project has previous records of noncompliance
- Projects involving vulnerable populations that raise cause for concern
- Complex projects involving unusual levels or types of risks to participants
- Upon request by the investigator
- In response to inquiries from external regulatory agencies
The G-ACRE-IRB further notes that if the monitoring reveals serious or continuing noncompliance, the EC Secretariat or EC designee will compile the information regarding the allegation, complaint, or report and submit the information to the EC for further review and processing as needed. See the G-ACRE-IRB for additional information on monitoring procedures, reporting of monitoring results, and noncompliance.
As described in the G-ACRE-IRB, the ACRE IRB is also authorized to suspend or terminate an approved research study for a variety of reasons, including but not limited to:
- Failure to obtain appropriate consent or keep appropriate study-related paperwork
- Conduct of research activities without prior ACRE IRB approval
- Serious adverse event(s)
- Detrimental change in the risk-benefit ratio of the study
- Failure of investigators to complete required training
The convened board is specifically authorized to suspend or terminate approval of research protocols that are not being conducted in accordance with the ACRE IRB’s requirements or that has been associated with serious harm to the participants. The ACRE IRB Chair, or the designee, is authorized to suspend research protocols in emergency situations, such as when the rights, safety, or welfare of research participants are at immediate risk. Refer to the G-ACRE-IRB for detailed information on the board’s process for study suspension/termination, notification of the investigator, the consequences of study suspension/termination, and ACRE IRB requirements for permitting study reinstatement.
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
National Research Ethics Board of Liberia
As described in the G-NREB, the National Research Ethics Board of Liberia (NREB) must charge a minimal fee for the review of each submission type. Submissions include research protocols, re-submissions, amendments, and continuing reviews. The fee structure is based on the following application types: research protocol, behavioral research, investigational product (IP) (clinical trial), non-clinical trial, or waiver/exemption. Fees specifically associated with conducting a clinical trial involving IPs is based on a project’s scope, duration, sample size, and complexity as well as the types and quantities of IPs, among other criteria. The fees delineated in the G-NREB are as follows:
- Clinical trial: $7,000 USD
- Re-submission: $1,500 USD
- Continuing Review: $1,500 USD
- Amendment: $1,500 USD
Payment Instructions

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
There are no applicable regulations or guidance regarding the authorization of ethics committees (ECs) in Liberia. However, per G-NREB, the National Research Ethics Board of Liberia (NREB) is responsible for maintaining a registry of health research ECs and mitigating conflicts among ECs, researchers, and research entities.
Registration, Auditing, and Accreditation
No information is available on registration, auditing, and accreditation requirements.
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
According to the LibCTReg and the G-LibClinTrial, the National Research Ethics Board of Liberia (NREB) and the Liberia Medicines and Health Products Regulatory Authority (LMHRA) reviews may be conducted in parallel. However, per the G-LibClinTrial and the G-NREB, the LMHRA will only issue final approval once NREB approval is obtained.
Regulatory Authority Approval
The LibCTReg and the G-LibClinTrial indicate that upon receipt of a clinical trial application, the LMHRA screens the application package for completeness and must inform the applicant in writing about the validity of the application or the formal grounds for non-acceptance of the application within 10 working days of application receipt. If applicable, the applicant, in turn, must address formal grounds for non-acceptance within 10 working days.
The LibCTReg and the G-LibClinTrial further explain that after validation of a complete clinical trial application, the LMHRA must inform the applicant in writing about the outcome of the scientific assessment of the application within a maximum of 60 working days, or according to the following timeline for the different types of investigational products (IPs), unless otherwise specified by the LMHRA on a case-by-case basis:
- Pharmaceutical IPs: 45 working days
- Biological and biotechnology IPs: 60 working days
- Genetically modified organism IPs: 90 working days
As indicated in the LibCTReg and the G-LibClinTrial, these timelines exclude time taken for the applicant to respond to queries from the LMHRA during the review and decision process. If changes are required and the applicant fails to modify the application within a maximum of 30 working days, the application will be rejected. Per the G-LibClinTrial, during the clinical trial scientific assessment process, the LMHRA may request additional documents or changes through a query letter. Once a query has been raised and issued to the applicant, the process stops when the LMHRA receives a written response to the query. If the LMHRA requires changes to the application, and the applicant fails to modify the application within a maximum of 90 days, the application will be rejected.
As explained in the G-LibClinTrial, the LMHRA must issue a clinical trial certificate indicating the LMHRA clinical trial number to the applicant upon application approval. The clinical trial certificate may contain conditions required by the LMHRA with respect to the conduct or reporting of the trial. If the application is rejected, the applicant can submit a written appeal to the LMHRA’s Managing Director within 60 days of receipt of the rejection notice.
Per the G-LibClinTrial, in the case of expedited clinical trial application reviews, the LMHRA will review the application in no more than 14 working days for approved products and within 21 days for new products.
Additionally, per the G-LibClinTrial, the LMHRA must respond to any substantial clinical trial amendment within 20 calendar days upon receipt of the written decision from the NREB.
Ethics Committee Approval
National Research Ethics Board of Liberia
Pursuant to the G-NREB, principal investigators (PIs) are required to submit new research protocols no later than one (1) month prior to the next bi-monthly board meeting. The NREB should notify PIs in writing of its decision within two (2) weeks following a board meeting, where applicable, following a complete review of the protocols. The G-NREB does not specify an approval expiration date.
The G-NREB explains that for protocol amendments, the NREB Secretariat, in consultation with the Chair, will make a determination regarding the type of review (full board review or expedited given the risk) and will notify the investigator within three (3) weeks upon submission per the board’s decision. Expedited reviews must take no more than three (3) weeks, and if any committee member raises a concern about a protocol that was expedited, the protocol must undergo a full board review.
Refer to the G-NREB for additional information on the various submission types that may be submitted to the board and their corresponding review and approval processes.
Atlantic Center for Research and Evaluation Institutional Review Board
As specified in the G-ACRE-IRB, PIs are required to submit all application materials to the Atlantic Center for Research and Evaluation Institutional Review Board (ACRE IRB) four (4) weeks in advance of the date that a decision is requested. (Note: Per LBR-28, due to a Memorandum of Understanding (MOU) between the NREB and the ACRE IRB in 2022, the ACRE IRB does not review and approve clinical trial protocols. All clinical trial protocols submitted to the ACRE IRB are referred to the NREB.) In the case of full review studies, submission is required four (4) weeks prior to the next scheduled ACRE IRB meeting. The ACRE IRB will convene a special meeting, if necessary, to accommodate the PI’s compliance with an external funding deadline; however, submission is required four (4) weeks prior to the special meeting date.
As specified in the G-ACRE-IRB, the ACRE IRB approval will commence on the day the study is approved and will expire within a defined time period based on a risk assessment and regulations. If specific conditions are stipulated in the approval letter, those conditions must be met by the designated date or approval may be withdrawn. No timeline of review is specified for the ACRE IRB’s review. However, the G-ACRE-IRB states that the clinical research protocol and accompanying documents are approved as they are submitted.
The G-ACRE-IRB states that the ACRE IRB must also review and approve any clinical research protocol amendments prior to those changes being implemented. The clinical research protocol submission is reviewed either via expedited procedures (for minor changes) or via full board review (for all other changes). Refer to the G-ACRE-IRB for clinical research protocol amendment documentation submission and procedural requirements.
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.
Overview
In accordance with the LMHRA-Act, the LibCTReg, and the G-LibClinTrial, a clinical trial can only commence after the sponsor or the representative receives authorization from the Liberia Medicines and Health Products Regulatory Authority (LMHRA). The LibCTReg and the G-LibClinTrial, in turn, state that the sponsor, the legal representative, the principal investigator (PI), or the sponsor-investigator must obtain written permission from the National Research Ethics Board of Liberia (NREB). In addition, per the G-LibClinTrial, the appointed PI must provide proof of residency in Liberia in the clinical trial application submission package.
As per the G-LibClinTrial, the sponsor or the representative is required to obtain LMHRA approval for the clinical trial before the import of an investigational product (IP) to be used in the trial is authorized. However, parallel submission for approval of the clinical trial and the permit to import the IP is possible if the import permit application is included in the clinical trial application submission package.
In addition, per the LibCTReg, the applicant must inform the LMHRA in writing of the exact clinical trial commencement date (i.e., first patient first visit). If the trial does not begin within 90 calendar days from issuance of the clinical trial certificate, the applicant must show cause for the failure to commence as scheduled and solicit issuance of a new clinical trial certificate. Pursuant to Part VIII of the LMHRA-Act, the LibCTReg delineates that failure to inform the LMHRA of the commencement or not starting the clinical trial within this period will have regulatory implications including, but not limited to, the payment of administrative charges for the re-issuance of the clinical trial certificate on its expiration.
The LibCTReg also states that the sponsor, the investigator, and all of the persons involved in the clinical trial must fulfill the requirements of good clinical practice in accordance with the International Council for Harmonisation’s Guideline for Good Clinical Practice E6(R2) (LBR-8) and the World Health Organization (WHO)'s Guidelines for Good Clinical Practice (GCP) for Trials on Pharmaceutical Products (LBR-25) as determined by the LMHRA. The G-LibClinTrial further specifies that the LMHRA has adopted LBR-8 for use along with the LMHRA guidelines.
Clinical Trial Agreement
While a signed clinical trial agreement is not an official requirement, the G-LibClinTrial states that the protocol should contain a statement that the trial will be conducted in compliance with the protocol, LBR-8, and the applicable regulatory requirements. The protocol should also be signed and dated by both the sponsor or the representative and the PI to document the investigator’s and the sponsor’s agreement to the protocol. If the protocol is not signed and dated by both parties, a corresponding declaration signed and dated by both must be provided to the LMHRA with the application.
Clinical Trial Registration
As delineated in the LibCTReg, the sponsor or the sponsor-investigator must register all clinical trials with a public international database. The G-LibClinTrial further specifies that the LMHRA requires the sponsor or the representative to provide proof of registration with the Pan African Clinical Trials Registry (PACTR) (LBR-36) or another WHO Primary Registry (LBR-35).
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
According to the LibCTReg, the G-LibPV, and the G-ACRE-IRB, the following definitions provide a basis for a common understanding of Liberia’s safety reporting requirements (Note: Each of the items listed below will not necessarily be found in all sources, which provide overlapping and unique elements):
- Adverse Event (or Adverse Experience) (AE) – Any untoward medical occurrence in a participant to whom a medicinal product has been administered, including occurrences which are not necessarily caused by or related to that product, or any abnormal sign (e.g., any abnormal physical exam or laboratory finding), symptom, or disease, temporally associated with the participant’s involvement in the research; AEs encompass both physical and psychological harms
- Adverse Drug Reaction (ADR) – Any noxious and unintended responses in a participant to an investigational medicinal product which is related to any dose administered to that participant. A causal relationship between a medicinal product and an adverse event is at least a reasonable possibility, i.e., the relationship cannot be ruled out
- 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, is a congenital anomaly/birth defect, or may jeopardize the participant’s health and may require medical or surgical intervention based upon appropriate medical judgment (e.g., the development of drug dependency or drug abuse). A causal relationship between a medicinal product and an adverse event is at least a reasonable possibility, i.e., the relationship cannot be ruled out
- Unexpected Adverse Drug Reaction – An adverse reaction where the nature or severity is inconsistent with the applicable product information (e.g., Investigator's Brochure for an unapproved investigational product (IP) or package insert/summary of product characteristics for an approved product)
Safety Reporting Requirements
Per the LibCTReg and the G-LibClinTrial, the principal investigator (PI) or the sponsor should report any SAEs/SADRs suspected to be related to the IP immediately, and in any event, no later than three (3) calendar days after becoming aware of the event to the Liberia Medicines and Health Products Regulatory Authority (LMHRA) and the National Research Ethics Board of Liberia (NREB). Per the G-LibClinTrial, in the case of multicenter trials involving clinical trial sites (in and outside of Liberia), the PI or sponsor must submit all SAEs/SADRs deemed to be related to the IP within 15 calendar days to the LMHRA and the NREB. The PI or the sponsor is also required to indicate the timelines allocated for related investigations.
The G-LibPV provides the following scale by which to assess the severity of AEs/ADRs: Mild, Moderate, Severe, or Fatal. For more details, see Table 2 in G-LibPV. The G-LibPV also provides criteria for determining the link between the intervention and the AEs/ADRs as either certain, probably/likely, possible, unlikely, conditional/unclassified, or un-assessable/unclassified. For more details, see Table 3 in G-LibPV.
Investigator Responsibilities
The G-NREB indicates that investigators are required to submit a report to the NREB for all AEs except those resulting in death within seven (7) calendar days. Investigator(s) must report all deaths that are possibly, probably, or definitely related to the study within 24 hours to the NREB.
Other events that must be reported to the NREB include the following:
- Unanticipated problems involving risks to participants or others
- Non-compliance (including major protocol deviations and non-compliance unrelated to a protocol deviation)
- New information that might affect the willingness of participants to enroll or continue to participate in the study
As indicated in the G-ACRE-IRB, for studies using the Atlantic Center for Research and Evaluation Institutional Review Board (ACRE IRB), the investigator must promptly report any unanticipated problems to the ACRE IRB in accordance with the following guidelines (Note: Per LBR-28, due to a Memorandum of Understanding (MOU) between the NREB and the ACRE IRB in 2022, the ACRE IRB does not review and approve clinical trial protocols. All clinical trial protocols submitted to the ACRE IRB are referred to the NREB.):
- Unanticipated problems that are SAEs must be reported to the ACRE IRB within five (5) business days of the investigator becoming aware of the event. The board strongly recommends that a preliminary report be submitted by the investigator within 48 hours of learning of the SAE with a formal follow-up report submitted within the above timeline
- Any other unanticipated problem should be reported to the ACRE IRB within two (2) weeks of the investigator becoming aware of the problem. The board strongly recommends that a preliminary report be submitted by the investigator within five (5) business days of learning of the unanticipated problem with a formal follow-up report submitted within the above timeline
In addition, per the G-ACRE-IRB, when making a report to the ACRE IRB, the investigator should include the following information:
- The appropriate identifying information for the research protocol, such as the title, the investigator’s name, and the ethics committee (EC) project number
- A detailed description of the AE, incident, experience, or outcome; however, to maintain confidentiality, participants’ names and identifiable information should not be included in the report
- An explanation of the basis for determining that the AE, incident, experience, or outcome represents an unanticipated problem
- A description of any changes to the protocol or other corrective actions that have been taken or are proposed in response to the unanticipated problem
Other Safety Reports
As explained in the G-ACRE-IRB, for studies using the ACRE IRB, the ACRE IRB Executive Committee conducts the initial review of unanticipated problems. This committee is authorized to take the following actions in response to any incident report:
- Conduct an administrative review of the report, including assessing whether the incident constitutes an unanticipated problem
- If a convened ACRE IRB review is needed, the Chair assigns the incident report for review at the next available regularly scheduled ACRE IRB meeting
- Alternately, the ACRE IRB Executive Committee may convene an emergency meeting of the ACRE IRB to review the report
- If the ACRE IRB Executive Committee finds that the rights, safety, and welfare of the participants are jeopardized by the research, the Chair may suspend the research until such time when the full ACRE IRB can convene to review the report. When reviewing a particular incident, experience, or outcome reported as an unanticipated problem by the investigator, the board may determine that the incident, experience, or outcome does not meet the criteria for an unanticipated problem
Following a review of the unanticipated problem report, per the G-ACRE-IRB, the ACRE IRB may require the following actions, in order to protect the ongoing safety of the research participants:
- Modification of participant inclusion or exclusion criteria to mitigate the newly identified risks
- Implementation of additional procedures for monitoring participants
- Modification of informed consent documents to include a description of newly recognized risks
- Addition of provisions about newly recognized risks to previously enrolled participants
- Suspension of enrollment of new participants
- Suspension of research procedures in currently enrolled participants
- Suspension of the entire study
- Termination of approval for the entire study
Per the G-ACRE-IRB, if the solution to an unanticipated problem is to amend the research protocol and/or informed consent forms, then an amendment request must be made to the ACRE IRB. If the changes are minor, they may be reviewed by expedited review procedures. If the changes are major, they must be reviewed and approved by the convened board. Changes made in response to an unanticipated problem must be reviewed and approved by the ACRE IRB before being implemented, except where implementation is necessary to eliminate immediate hazards to research participants.
Form Completion & Delivery Requirements
Liberia Medicines and Health Products Regulatory Authority
As per the G-LibPV, all SAEs/SADRs and SUSARs must be reported on the LMHRA’s Suspected Adverse Drug Reaction Reporting Form (Annex 3 in the G-LibClinTrial).
Atlantic Center for Research and Evaluation Institutional Review Board
Per LBR-28, since all clinical trials protocols submitted to the ACRE IRB are referred to the NREB for review, all AEs/ADRs and SAEs/SADRs are only sent to the NREB.
National Research Ethics Board of Liberia
No information is available on NREB safety reporting forms and delivery requirements.
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.

Per the G-ACRE-IRB, PI(s) should complete Section 12 (Disposition of Project) of the ACRE IRB Submission Form (Section 25.02 in Article XXV of the G-ACRE-IRB) for the final ACRE IRB review. For the board’s purposes, the project has ended when there is no further participant enrollment, intervention(s), or data collection, and the remaining data are either de-identified or maintained with safeguards. The PI(s) should use this section to describe the disposition of the project and its data and provide a brief summary of their 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 stated in the LibCTReg and the G-LibClinTrial, the Liberia Medicines and Health Products Regulatory Authority (LMHRA) has adopted the International Council for Harmonisation's Guideline for Good Clinical Practice E6(R2) (LBR-8) for use along with LMHRA guidelines. Per LBR-8 and the LibCTReg, the sponsor is defined as an individual, company, institution, or organization that takes responsibility for the initiation, management, and/or financing of a clinical trial.
LBR-8 and the LibCTReg also define a sponsor-investigator as an individual who both initiates and conducts an investigation, and under whose immediate direction the investigational product is administered or dispensed. The term does not include any person other than an individual. The obligations of a sponsor-investigator include both those of a sponsor and those of an investigator.
In addition, per the LibCTReg, the sponsor may hire a contract research organization (CRO) (commercial, academic, or other) to perform one (1) or more of the sponsor’s trial-related duties and functions. LBR-8 further explains that although a sponsor may transfer responsibility for any or all of the sponsor’s obligations to a CRO, the ultimate responsibility for the trial data’s quality and integrity always resides with the sponsor. The sponsor should also ensure oversight of any trial-related duties and functions carried out on its behalf, including trial-related duties and functions that are subcontracted to another party by the sponsor’s CRO. Any trial-related responsibilities transferred to a CRO should be specified in writing. The CRO should implement quality assurance and quality control.
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
According to the LibCTReg and the G-LibClinTrial, the Liberia Medicines and Health Products Regulatory Authority (LMHRA) has adopted the International Council for Harmonisation's Guideline for Good Clinical Practice E6(R2) (LBR-8) for use along with LMHRA guidelines. Per LBR-8, the sponsor is responsible for selecting the investigator(s) and the institution(s) for the clinical trial. Each investigator should be qualified by training and experience and should have adequate resources to properly conduct the trial for which the investigator is selected. LBR-8 also explains that the sponsor should utilize appropriately qualified individuals to supervise the overall conduct of the trial, to handle the data, to verify the data, to conduct the statistical analyses, and to prepare the trial reports.
As indicated in LBR-8, the investigator(s) should be qualified by education, training, and experience to assume responsibility for the proper conduct of the trial, should meet all the qualifications specified by the applicable regulatory requirement(s), and should provide evidence of such qualifications through up-to-date curriculum vitae (CV) and/or other relevant documentation requested by the sponsor, the ethics committee (EC), and/or the regulatory authority(ies) (see section 4 in LBR-8 for detailed investigator requirements).
As stated in the G-LibClinTrial, all investigators must be trained in good clinical practices (GCP) documented by the provision of training certificates not older than three (3) years at the time of application. Any other training or experience from previous clinical trials and patient care as needed for the conduct of the trial must be provided for the investigators to prove their qualifications. The principal investigators (PIs) should have acted as PI or at least as an investigator in at least one (1) prior clinical trial and must provide proof of residency in Liberia in the clinical trial application submission package. The LibCTReg also states that the trial is to be conducted in an appropriate facility by a suitably qualified investigator in a responsible manner and managed by an investigator who can provide evidence of sufficient experience in the conduct of clinical trials as determined by the LMHRA.
Per the G-NREB, PIs are also required to be able to provide a current Certificate of Training in GCP for PIs, be qualified to undertake the particular study, and be knowledgeable in the values and tenets of ethical and regulatory principles and scientific method applications associated with conducting research in human participants.
In addition, the G-LibClinTrial requires the applicant to provide details of the site(s) where the clinical trial is to be conducted and a duly justified written statement on the suitability of the trial sites adapted to the nature and use of the investigational product in the clinical trial application submission package. The statement should include a description of the suitability of facilities, equipment, human resources, and description of expertise, issued by the head of the clinic/institution at the trial site or by some other responsible person.
Furthermore, per LBR-8, the sponsor should obtain the investigator's/institution's agreement to:
- Conduct the trial in compliance with GCP, the applicable regulatory requirement(s), and the approved protocol
- Comply with procedures for data recording/reporting
- Permit monitoring, auditing, and inspection
- Retain the trial related essential documents until the sponsor informs the investigator/institution these documents are no longer needed
The sponsor and the investigator/institution should sign the protocol, or an alternative document, to confirm this agreement.
Foreign Sponsor Responsibilities
No information is available on foreign sponsor requirements.
Data and Safety Monitoring Board
As per the G-LibClinTrial, the sponsor or the representative should provide information on the composition of the Data and Safety Monitoring Board (DSMB) in the clinical trial application submission package. This information should include the list of members, the terms of reference, and the CVs of its members to justify their expertise as members of the DSMB.
LBR-8 further indicates that the sponsor may consider establishing a DSMB (also known as an independent data monitoring committee (IDMC)) to assess the progress of a clinical trial, including the safety data and the critical efficacy endpoints at intervals, and to recommend to the sponsor whether to continue, modify, or stop a trial. The DSMB should have written operating procedures and maintain written records of all its meetings.
Multicenter Studies
As delineated in LBR-8, 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 are given 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 among investigators is facilitated
Further, per LBR-8, if the organization of a coordinating committee and/or selection of coordinating investigator(s) are to be used in multicenter trials, their organization and/or selection are the sponsor's responsibility.
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 LibCTReg and the G-LibClinTrial, the applicant should include documentation in the clinical trial application submission package to verify active clinical trial insurance that covers phases I, II, and III, proof of professional indemnity (malpractice insurance), and proof of sponsor indemnification for investigators and the trial site. The LibCTReg also notes that an indemnity in the form determined by the Liberia Medicines and Health Products Regulatory Authority (LMHRA) is to be signed by the participant protecting the LMHRA from liability related to an injury or an adverse event which may be sustained by a person, directly or indirectly, as a result of the conduct of the trial and which occurs or reveals itself at the time of the trial or subsequently.
The G-LibClinTrial also specifies that a study insurance certificate and an indemnity provision should be current and valid for the full duration of the trial and follow-up period. If the validity is shorter, a written renewal commitment for the trial duration is required. The certificate should contain a reference to the clinical trial, the clinical trial protocol number, and the countries to which the insurance cover is extended. The insurance cover should be provided from an internationally recognized company. Additionally, the LibCTReg, requires an insurance policy to be in place to provide benefits in the event that a clinical trial participant suffers injury or death related to the study.
Per LBR-29, both clinical trial insurance and indemnification certificates must be included in the clinical trial application dossier in accordance with the African Vaccine Regulatory Forum (AVAREF)’s Clinical Trial Application Checklist (LBR-1). According to LBR-4, the AVAREF was established by the World Health Organization (WHO) in 2006 to promote the harmonization of ethics and regulatory processes in Africa.
In addition, per the G-LibClinTrial, under certain circumstances, the Liberia Medicines and Health Products Regulatory Authority (LMHRA) may accept an expedited application and review process for clinical trials (e.g., epidemics or other urgent public health interests requiring fast use of new medicines or health products and/or fast gathering of health product information). In the case of trials involving human participants, the applicant must provide proof of current, relevant, and appropriate study insurance for all participants or professional indemnity insurance for investigators as part of the application submission package to be sent to the LMHRA. Furthermore, as specified in the LibCTReg and the G-LibClinTrial, the LMHRA has adopted the International Council for Harmonisation's Guideline for Good Clinical Practice E6(R2) (LBR-8) for use along with the LMHRA guidelines. LBR-8 states that if required by the applicable regulatory requirement(s), the sponsor should provide insurance or should indemnify (legal and financial coverage) the investigator/the institution against claims arising from the trial, except for claims that arise from malpractice and/or negligence.
Compensation
Injury or Death
Per LBR-8, the sponsor or the representative is responsible for providing compensation to research participants and/or their legal heirs in the event of trial-related injuries or death.
LBR-8 states that the sponsor's policies and procedures should address the treatment costs of trial participants in the event of trial-related injuries, and when trial participants receive compensation, the method and manner of compensation should comply with applicable regulatory requirement(s). According to LBR-29, the LMHRA does not have a compensation committee.
In addition, per the LibCTReg, any person(s), institution(s), corporate entity(ies), their designees, or legal representative(s) who does not provide insurance coverage for prospective participants as required, and in the course of the research bodily injury or substantial harm results, the person(s), institution(s), corporate entity(ies), their designees, or legal representative(s) commits a first degree misdemeanor consistent with the PenalLaw. The PenalLaw states a person commits a misdemeanor of the first degree if the person recklessly engages in conduct which creates a substantial risk of death or serious bodily injury to another.
Pursuant to Part VIII of the LMHRA-Act, the LibCTReg also specifies that the principal investigator or organization is subject to an action of damages for any Serious Adverse Event (SAE)/Serious Adverse Drug Reaction (SADR) that is life-threatening, or results in persistent or significant disability/incapacity or congenital anomaly/birth defect, during the conduct of a clinical trial. Additionally, any SAE that results in the death of a participant during the conduct of a clinical trial must constitute negligent homicide consistent with the PenalLaw which states that a person is guilty of negligent homicide if the person causes the death of another human being negligently; negligent homicide is a felony of the third degree.
Trial Participation
Per LBR-8, the participant should be provided with information regarding any anticipated prorated payment, if any, for participating in the trial.
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

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
As specified in the LibCTReg and the G-LibClinTrial, the Liberia Medicines and Health Products Regulatory Authority (LMHRA) has adopted the International Council for Harmonisation (ICH)'s Guideline for Good Clinical Practice E6(R2) (LBR-8) for use along with the LMHRA guidelines. Per LBR-8, sponsors are responsible for implementing and maintaining 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 LBR-8, 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:
- During protocol development, identifying processes and data that are critical to ensure participant protection and the reliability of trial results
- 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 communicate 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
- In the clinical study report, describing the quality management approach implemented in the trial and summarize important deviations from the predefined quality tolerance limits and remedial actions taken (Refer to the ICH’s Structure and Content of Clinical Study Reports (E3) guidelines (LBR-37))
Pursuant to Part VIII of the LMHRA-Act, the LibCTReg states that any person(s), institution(s), corporate entity(ies), their designees, or legal representatives who violates the clinical trial authorization procedures, the serious adverse event notification requirements, and/or the suspension/withdrawal provisions delineated in the LibCTReg will be liable to pay administrative fines. See the LibCTReg for details.
Monitoring Requirements
Per LBR-8, if or when sponsors perform audits as part of implementing quality assurance, they should consider the following:
- The purpose of the audit should be to evaluate trial conduct and compliance with the protocol, SOPs, good clinical practice (GCP), and applicable regulatory requirements
- The selection and qualification of auditors who are independent of clinical trials/systems to conduct audits; the sponsors should ensure the auditors are qualified by training and experience to conduct audits properly and have appropriate qualifications that should be documented
- Auditing procedures that ensure the auditing of clinical trials/systems is conducted in accordance with the sponsor’s written procedures on what to audit, how to audit, the frequency of audits, and the form and content of audit reports
In addition, per LBR-8, 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).
Refer to LBR-8 additional audit procedure details.
Premature Study Termination/Suspension
Pursuant to the LibCTReg, if the trial is suspended or terminated before its purpose is achieved, the applicant must convey the reason(s) in writing to the LMHRA and the National Research Ethics Board of Liberia (NREB) within 10 working days and all information must be provided as determined by the LMHRA. The G-LibClinTrial also states that the applicant must inform the LMHRA of a clinical trial suspension or premature termination of a clinical trial within 10 working days and clearly explain the reasons for this decision. LBR-8 further explains that if a trial is prematurely terminated or suspended, the sponsor should promptly inform the investigator(s)/institution(s) and the regulatory authority(ies) of the termination or suspension and the reason(s) for the termination or suspension. The ethics committee (EC) should also be informed promptly and provided the reason(s) for the termination or suspension by the sponsor or by the investigator/institution, as specified by the applicable regulatory requirement(s). Additionally, according to LBR-8, 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 sponsor should promptly inform the EC and provide the reason(s) for the termination or suspension.
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
As specified in the LibCTReg and the G-LibClinTrial, the Liberia Medicines and Health Products Regulatory Authority (LMHRA) has adopted the International Council for Harmonisation (ICH)'s Guideline for Good Clinical Practice E6(R2) (LBR-8) for use along with the LMHRA guidelines.
As per LBR-8, 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. Sponsors 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, sponsors should maintain standard operation 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 in their use. Refer to LBR-8 for additional information.
Records Management
The G-LibClinTrial specifies that the principal investigator (PI) must keep an Investigator Site File (ISF), and the sponsor must keep a Trial Master File (TMF) containing essential documents relating to the clinical trial, which provide verification for the trial conduct and the quality of the data generated, taking into account all trial characteristics. The files must be readily available and directly accessible upon request from the LMHRA. The sponsor and the investigator must archive the contents of the TMF and ISF, respectively, for at least 25 years after the end of the trial including the medical files of study participants.
As set forth in LBR-8, the sponsor should inform the investigator(s)/institution(s) in writing of the need for record retention and should notify the investigator(s)/institution(s) in writing when the trial related records are no longer needed. Sponsor-specific essential documents should be retained for at least two (2) years after the last approval of a marketing application, until there are no pending or contemplated marketing applications, or at least two (2) years have elapsed since the formal discontinuation of the investigational product’s clinical development. The sponsor should inform the investigator(s) and the institution(s) in writing when trial-related records are no longer needed.
In addition, LBR-8 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. Per LBR-8, the sponsor should ensure the protocol or other written agreement specify that the investigator(s)/institution(s) provide direct access to source data/documents for trial related monitoring, audits, ethics committee review, and regulatory inspection.
As per the G-LibClinTrial, data handling and recordkeeping should be conducted in conformity with the World Health Organization's Good Clinical Practice Guidelines (LBR-25) (refer to Section 8 for details).
Per the G-ACRE-IRB, for clinical research studies using the Atlantic Center for Research and Evaluation Institutional Review Board (ACRE IRB), the ACRE IRB must retain all relevant records (e.g., study documents specific to board activities and administrative documents related to ACRE IRB internal operations) per the following timelines (Note: Per LBR-28, due to a Memorandum of Understanding (MOU) between the National Research Ethics Board of Liberia (NREB) and the ACRE IRB in 2022, the ACRE IRB does not review and approve clinical trial protocols. All clinical trial protocols submitted to the ACRE IRB are referred to the NREB.):
- All records regarding a research application (regardless of whether it is approved) must be retained for at least three (3) years
- All records regarding all applications that are approved, and the research initiated must be retained for at least three (3) years after completion of the research
- Denied applications will be treated as terminated files and records must be retained for three (3) years after the denial of the research
The G-ACRE-IRB further explains the research records from a study must be retained by the investigator(s) for a period of no more than five (5) years following the closure date. If other regulations and policies apply to a particular protocol, then the duration of protocol retention is in accordance with the applicable regulations/policies. For detailed ACRE IRB recordkeeping requirements, refer to the G-ACRE-IRB.
The G-ACRE-IRB also specifies that although a research protocol has been closed, the investigator(s) should keep the data they have collected, including identifiable private data, in a manner consistent with the board-approved protocol and participant consent requirements. The investigator(s) must continue to honor any confidentiality protections of the data. Refer to the Informed Consent topic for additional information on documentation requirements and research participant rights during the informed consent process.
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
No information is available related to responsible parties for personal data protection.
Data Protection
No information is available related to data protection.
Consent for Processing Personal Data
As stated in the LibCTReg, the clinical trial participant must be informed of the purpose and scope of the collection and use of personal data, especially medical data. The trial participant must be informed especially of the fact that where necessary, the collected data should be:
- Kept available for inspection by the Liberia Medicines and Health Products Regulatory Authority (LMHRA) or for monitoring or auditing by the sponsor in order to verify the proper conduct of the clinical trial
- Be passed on to the sponsor and the LMHRA without disclosing the identity of the trial participant
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 accordance with the LibCTReg and the G-LibClinTrial, the Liberia Medicines and Health Products Regulatory Authority (LMHRA) has adopted the International Council for Harmonisation's Guideline for Good Clinical Practice E6(R2) (LBR-8) for use along with the LMHRA guidelines. Per LBR-8, a freely given informed consent must be obtained from every study participant prior to clinical trial participation. According to the G-ACRE-IRB, the G-NREB, and LBR-8, the informed consent form (ICF) is viewed as an essential document that must be reviewed and approved by an ethics committee (EC).
As delineated in the LibCTReg, the trial participant should be informed of the nature, significance, and implications of the clinical trial and have given a voluntary written informed consent. The trial participant or witness, if applicable, must be informed by an investigator, who is a healthcare professional or a person designated by the investigator, and who is knowledgeable about the nature, significance, risks, and implications of the clinical trial as well as about the participant’s right to withdraw from the clinical trial at any time. A generally comprehensible information sheet is to be handed out to the participant. The trial participant is also to be given the opportunity to have a counseling session with an investigator or a person designated by the investigator about the other conditions surrounding the conduct of the clinical trial.
The LibCTReg further notes that a declaration of consent to participate in a clinical trial can be revoked at any time in the presence of the investigator or a member of the investigating team, orally or in writing, without disadvantage to the trial participant. In the case of a revocation of consent, the study participant must decide whether their stored data may continue to be used.
Per the G-ACRE-IRB, the Atlantic Center for Research and Evaluation Institutional Review Board (ACRE IRB) must assess the study to ensure the voluntary, non-coercive recruitment of research participants. The board must ensure that they have adequately considered the following in the protocol (Note: Per LBR-28, due to a Memorandum of Understanding (MOU) between the National Research Ethics Board of Liberia (NREB) and the ACRE IRB in 2022, the ACRE IRB does not review and approve clinical trial protocols. All clinical trial protocols submitted to the ACRE IRB are referred to the NREB.):
- Procedures for obtaining informed consent
- Content of the participant information sheet
- Content and language of the informed consent document
- Translation of the informed consent document into the local language
- The language used in the documents should be simple relative to the general public’s level of understanding
- Contact persons with their addresses and telephone numbers (for both the study team and the EC)
- Privacy and confidentiality
- Risks (physical, mental, social)
- Benefits to participants and to others
- Compensation (reasonable/unreasonable)
- Involvement of vulnerable participants
- Provision for medical/psychosocial support
- Treatment for study-related injuries
- Use of biological materials
Per the G-ACRE-IRB, if the informed consent procedures and consent document(s) are reviewed by the ACRE IRB Secretariat and found to be complete, the documentation is then submitted to the board for review. If the documentation qualifies for expedited review, the chairperson or a designated expedited reviewer will evaluate the materials. After the investigator makes the required changes suggested by the ACRE IRB, the application may be approved by the chair.
(See the Required Elements section for details on what should be included in the ACRE IRB and NREB forms. Refer to LBR-33 for the NREB Exempt Human Research Consent Script Form and LBR-34 for the NREB Short Consent Form.)
LBR-8 states that the investigator or the designated representative must provide detailed research study information to the participant or legal representative/guardian. LBR-8 further specifies 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 or legal representative/guardian, should also be given adequate time to consider whether to participate.
Further, per LBR-8, 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 the 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.
Re-Consent
According to LBR-8, the LMHRA and an EC should approve any change in the ICF due to a protocol modification before such changes are implemented. The participant or legal representative/guardian should be informed in a timely manner if new information becomes available that might be relevant to the participant’s willingness to continue participation in the trial. The participant or legal representative/guardian will also be required to re-sign the revised ICF and receive a copy of any amended documentation.
In addition, per the G-ACRE-IRB, in the case that ACRE IRB approval is reinstated, the ACRE IRB may require previously enrolled participants to re-consent.
Language Requirements
As stated in the G-LibClinTrial, all clinical trial application documentation must be submitted in English. If documents are written in another language, a certified translation is required.
Documenting Consent
The LibCTReg states that if the trial participant is unable to read or write English, the informed consent should be obtained in the language the participant understands and in the presence of at least one (1) witness. The witness, who should be able to read and write English and understand the local language in which the trial participant is informed, should not be a member of the investigating team. The consent given by the trial participant must be documented in writing, dated, and signed by the witness and thumb printed by the trial participant.
Per LBR-8, before participating in the study, the participant or legal representative/guardian should receive a copy of the signed and dated ICF. The participant or legal representative/guardian should also receive a copy of the signed and dated consent form updates and a copy of any amendments to the written information provided to the participants.
LBR-34 also provides a sample NREB ICF for adults capable of consent. A witness must also be present during the consent process and the witness must sign and date the ICF. The number of copies to be signed and distributed is not specified.
Per LBR-8, if a participant is unable to read or if a legally acceptable representative is unable to read, an impartial witness should be present during the entire informed consent discussion. The witness should sign and date the ICF after the following steps have occurred:
- The written ICF and any other written information provided to the participant is read and explained to the participant and legal representative/guardian
- The participant and legal representative/guardian, have orally consented to the participant’s involvement in the trial, and has personally signed and dated the ICF, if capable of doing so
Waiver of Consent
As specified in the G-ACRE-IRB, to obtain a waiver or alteration of informed consent, the investigator must include the request (and provide justification for the waiver or alteration) in the protocol submission to the ACRE IRB. The request for waiver or alteration will be reviewed by the convened board, the ACRE IRB Chair, or the designated expedited reviewer. The ACRE IRB reviewer (Chair or designee) may approve the waiver or alteration of informed consent, if the board reviewer can establish that the research is to be conducted by or subject to the approval of state or local government officials and is designed to study, evaluate, or otherwise examine:
- Public benefit or service programs
- Procedures for obtaining benefits or services under those programs
- Possible changes in or alternatives to those programs or procedures, or
- Possible changes in methods or levels of payment for benefits or services under those programs
The ACRE IRB reviewer should also be able to ascertain that the research could not practicably be carried out without the waiver or alteration.
Additionally, per the G-ACRE-IRB, the ACRE IRB reviewer may approve the waiver or alteration of informed consent, if the reviewer determines the following:
- The research involves no more than minimal risk to the participants
- The research could not practicably be conducted without the requested waiver or alteration
- If the research involves using identifiable private information or identifiable biospecimens, the research could not practicably be carried out without using such information or biospecimens in an identifiable format
- The waiver or alteration will not adversely affect the rights and welfare of the participants, and
- Whenever appropriate, the participants or legal representative/guardian will be provided with additional pertinent information after participation. The ACRE IRB reviewer will document the findings for waiver or alteration of informed consent. An alteration to informed consent may apply when conducting a study where there is deception or an incomplete disclosure (for example, studies that require deception because the study would be compromised if participants were told the true purpose)
In addition, the G-ACRE-IRB explains that a waiver of a signed ICF may be appropriate for some research studies such as survey or interview studies containing highly sensitive questions (e.g., health status, sexual practices, criminal behavior, etc.), or surveys containing non-sensitive information. To obtain a waiver of documented (signed) informed consent, the investigator must include the request (and provide justification for the waiver or alteration) in the protocol submission process. The request for waiver or alteration will be reviewed by the convened ACRE IRB, the Chair, or the designated expedited reviewer. The ACRE IRB reviewer will consider the investigator’s request and review the request to determine if:
- The only record linking the participant and the research would be the consent document, and the principal risk would be potential harm resulting from a breach of confidentiality
- The research presents no more than minimal risk of harm to participants and involves no procedures for which written consent is normally required outside of the research context
- The participants or legal representative/guardian are members of a distinct cultural group or community in which signing forms is not the norm, that the research presents no more than minimal risk of harm to participants, and provided that there is an appropriate alternative mechanism for documenting that informed consent was obtained. In cases where the documentation requirement is waived, the ACRE IRB may require the investigator to provide participants with a written statement regarding the research, such as an information sheet, instead of an informed consent document
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.
Liberia Medicines and Health Products Regulatory Authority
As specified in the LibCTReg and the G-LibClinTrial, the Liberia Medicines and Health Products Regulatory Authority (LMHRA) has adopted the International Council for Harmonisation's Guideline for Good Clinical Practice E6(R2) (LBR-8) to comply with informed consent requirements for use along with the LMHRA guidelines.

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
As specified in the LibCTReg and the G-LibClinTrial, the Liberia Medicines and Health Products Regulatory Authority (LMHRA) has adopted the International Council for Harmonisation's Guideline for Good Clinical Practice E6(R2) (LBR-8) for use along with the LMHRA guidelines. The G-ACRE-IRB also complies with the Council for International Organizations of Medical Sciences (CIOMS)’ International Ethical Guidelines for Health-related Research Involving Humans (LBR-2) and the national ethical guidelines for research on human participants. (Note: Per LBR-28, due to a Memorandum of Understanding (MOU) between the National Research Ethics Board of Liberia (NREB) and the ACRE IRB in 2022, the ACRE IRB does not review and approve clinical trial protocols. All clinical trial protocols submitted to the ACRE IRB are referred to the NREB.)
As per LBR-8, Liberia’s ethical standards promote respect for all human beings and safeguard the rights of research participants. LBR-8 and the G-ACRE-IRB state that a participant’s rights must also be clearly addressed in the informed consent form (ICF) and during the informed consent process.
The Right to Participate, Abstain, or Withdraw
As set forth in the G-ACRE-IRB, LBR-8, LBR-33, and LBR-34, 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
As per the G-ACRE-IRB, LBR-8, LBR-33, and LBR-34, a potential research participant or 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 a more detailed list.)
The Right to Privacy and Confidentiality
As per LBR-8 and the G-ACRE-IRB, 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-ACRE-IRB, LBR-8, LBR-33, and LBR-34, state that the research participant or legal representative/guardian should be provided with contact information for the sponsor and the investigator(s) to address trial-related inquiries.
The Right to Safety and Welfare
LBR-8 states that the research participant’s rights, safety, and well-being must take precedence over the interests of science and society.
(See the Required Elements and Vulnerable Populations sections for additional information regarding requirements for participant rights.)
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.
As set forth in the LibCTReg, in an emergency situation where consent cannot be obtained, treatment which is necessary without delay to save the life of the trial participant can be started immediately. Such situations must be defined by the Liberia Medicines and Health Products Regulatory Authority (LMHRA) and consent for continued participation must be obtained as soon as possible and not later than as defined by the National Research Ethics Board of Liberia (NREB) for a given clinical trial.
The LibCTReg and the G-LibClinTrial further explain that the LMHRA has adopted the International Council for Harmonisation's Guideline for Good Clinical Practice E6(R2) (LBR-8) for use along with the LMHRA guidelines. LBR-8 makes provisions to protect the rights of a research participant during the informed consent process when the procedure is complicated by medical emergencies in which prior consent from the participant is not possible.
As delineated in LBR-8, 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 the prior consent of the participant or legal representative/guardian cannot be obtained, the participant’s enrollment should follow measures specified in the protocol, and/or elsewhere, with documented LMHRA approval to protect the rights, safety, and well-being of the participant, and to ensure compliance with ethics committee (EC) and LMHRA requirements. The participant or the participant’s legal representative/guardian should be informed about the trial and provide consent as soon as possible.
Per the G-LibClinTrial, examples of emergency situations are epidemics or other urgent public health interests that require fast utilization of new medicines or health products and/or fast gathering of information on products. Information provided to clinical trial participants about the process of obtaining consent must be included in the documents submitted to the LMHRA. Refer to 2.3 of the G-LibClinTrial for additional information on how to submit an expedited clinical trial application package.
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 LibCTReg and the G-LibClinTrial explain that the Liberia Medicines and Health Products Regulatory Authority (LMHRA) has adopted the International Council for Harmonisation's Guideline for Good Clinical Practice E6(R2) (LBR-8) for use along with the LMHRA guidelines. According to LBR-8, research participants selected from vulnerable populations must be provided additional protections to safeguard their health and welfare during the informed consent process.
LBR-8 explains that vulnerable populations include those participants whose willingness to volunteer in a clinical trial may be unduly influenced by the expectation, whether justified or not, of benefits associated with participation, or of a retaliatory response from senior members of a hierarchy in case of refusal to participate. Examples may include, but are not limited to, members of a group with a hierarchical structure, such as medical, pharmacy, dental, and nursing students; subordinate hospital and laboratory personnel; employees of the pharmaceutical industry; members of the armed forces; and persons kept in detention. Other vulnerable study participants include patients with incurable diseases, persons in nursing homes, unemployed or impoverished persons, patients in emergency situations, ethnic minority groups, homeless persons, nomads, refugees, minors, and those incapable of giving consent.
Persons with Diseases
As indicated in the LibCTReg, in the case of a clinical trial on a person of legal age who is suffering from a disease for which the investigational product (IP) is to be used, one (1) of the following conditions should be applied along with the general clinical trial requirements delineated in the LibCTReg:
- The use of the IP is indicated according to the findings of medical science in order to save the person's life
- The IP must be of direct benefit to the group of patients who are suffering from the same disease as this person
Persons Under Legal Disability
As set forth in the LibCTReg, “persons under legal disability” are defined as being under the same category as a minor in terms of the individual’s ability to grant consent, except that the person under disability may be above the age of consent (18 years), but may be too ill to participate in decisions regarding their own health. In this case, priority is not given to parents or next of kin to petition the Probate Court for Guardianship, but priority is given to any natural person who demonstrates best interest in the welfare of the disabled.
The LibCTReg further explains that a person under legal disability may participate in a trial, if their parents/legal guardians have be informed of the nature, significance, and implications of the clinical trial and have given a written voluntary informed consent. If the informed implication is grave, it may be necessary for the guardian to secure the permission from the Probate Court before granting consent, due to the fact that the Decree of Guardianship has a clause that the Court appointed guardian should not release the disabled person to any other body in which case their welfare will be put at peril. Otherwise, it can be argued that the appointed guardian has breached their fiduciary duty to the Court by releasing the disabled person to peril.
See the Children/Minors and Mentally Impaired sections for additional information about these vulnerable populations.
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
According to the LibCTReg and the G-NREB, Liberia defines children and minors as those persons under 18 years of age. The G-NREB also defines adolescents as those between the ages of 15 and 17.
The LibCTReg also states that the definition of legal guardian or the “legal representative of a minor” is based on the premise that a minor cannot grant consent or enter into an agreement. According to LibCTReg, the interest of a minor must be firstly protected by the parents (the father if the parents are married or the child is legitimized) or the mother of the child if the parents are not married. Where there is no parent alive, especially the mother if the child is not born out of wedlock or legitimized, any next of kin, preferably the grandparents first, the siblings second, or any person with interest in the welfare of the child, may petition the Probate Court for Decree of Guardianship. A guardian must be authorized to give consent for the minor child. No institution can serve as guardian and give consent for research on the child. A guardian must be a natural person, not an institution.
Additionally, per the LibCTReg, a minor may participate in a trial, if their parents/legal guardians have been informed of the nature, significance, and implications of the clinical trial and have given a written voluntary informed consent. If the informed implication is grave, it may be necessary for the guardian to secure the permission from the Probate Court before granting consent, due to the fact that the Decree of Guardianship has a clause that the Court appointed guardian should not release the minor to any other body in which case their welfare will be put at peril. Otherwise, it can be argued that the appointed guardian has breached their fiduciary duty to the Court by releasing the minor or disabled to peril.
Also, as indicated in LibCTReg, in the case of a clinical trial on a minor who suffers or may suffer from a disease for which the investigational product (IP) is to be used, the following conditions should be applied:
- The use of the IP must be indicated according to the findings of medical science in order to save the life of the trial participant, to restore the participant to health, to alleviate suffering, or to prevent a disease
- The clinical trial must be of direct benefit to the group of patients suffering from the same disease as the trial participant
- The research must be absolutely necessary in order to confirm data obtained in clinical trials on other persons or by means of other research methods
- The research must relate to a clinical condition from which the minor concerned is suffering or may suffer
- The research may cause only minimal risk and minimal burden to the trial participant
LBR-34 also provides a sample National Research Ethics Board of Liberia (NREB) informed consent form (ICF) for children that explains the parents’ or guardian’s signatures document their permission for the child to take part in a research study as well as their permission for the use and disclosure of the child’s protected health information. If a second parent’s signature is not obtained, the first parent or guardian needs to choose one (1) of the following options on the form to justify why this is not possible:
- The ethics committee (EC) has determined that the permission of one (1) parent is sufficient (this option is only listed on the form if it has been approved by the EC)
- Second parent is deceased
- Second parent is unknown
- Second parent is incompetent
- Second parent is not reasonably available
- Only one (1) parent has legal responsibility for the care and custody of the child
In addition, an individual may provide permission as a guardian for a child only if that individual can provide a written document indicating that the individual is legally authorized to consent to the child’s general medical care and this documentation must be attached to the signed ICF. LBR-34 indicates that the EC must approve the consent form, a witness must be present during the consent process, and the witness must sign and date the ICF.
LBR-8 further states that when a clinical trial includes minors, the minor should be informed about the trial to the extent compatible with his or her understanding and, if capable, the minor should sign and personally date the written informed consent.
As delineated in the G-ACRE-IRB, the Atlantic Center for Research and Evaluation Institutional Review Board (ACRE IRB) must classify research involving children into one (1) of four (4) categories and document its discussion of the risks and benefits of the research study in order to approve such research. The risk/benefit categories are as follows (Note: Per LBR-28, due to a Memorandum of Understanding (MOU) between the NREB and the ACRE IRB in 2022, the ACRE IRB does not review and approve clinical trial protocols. All clinical trial protocols submitted to the ACRE IRB are referred to the NREB.):
- When the ACRE IRB determines that the risk is no more than minimal to children in a study, it may approve the research only if adequate provisions are made for soliciting the assent of the children and permission of their parents or legal guardians
- When the ACRE IRB determines that more than minimal risk to children is presented by a procedure that indicates the prospect of direct benefit to an individual child, or by a monitoring procedure that is likely to contribute to the child’s well-being, the ACRE IRB may approve the research if it is established that: the risk is justified by the anticipated benefit to the children; the relation of the anticipated benefit to the risk is at least as favorable to the children as that presented by available alternative approaches; and adequate provisions are made for soliciting the assent of the children and permission of their parents or legal guardians
- When the ACRE IRB determines that the study presents more than minimal risk to children and does not hold out the prospect of direct benefit for the individual child, but is likely to contribute generalizable knowledge about the child’s disorder or condition, the board may approve the research if it established that: the risk represents a minor increase over minimal risk; the study intervention or procedure presents experiences to participants that are reasonably 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 participants’ disorder or condition which is of vital importance for the understanding or improvement of the participants’ disorder or condition; and adequate provisions are made for soliciting the assent of the children and permission of their parents or legal guardians
- When the ACRE IRB determines that the research does not meet the requirements in any of the above three (3) categories, the board may only approve the research if it finds that the study presents a reasonable opportunity to further the understanding, prevention, or alleviation of a serious problem affecting the health or welfare of children
The G-ACRE-IRB further states that the ACRE IRB should ensure that adequate permissions are made for soliciting the permission of each child’s parent/legal guardian. The following provisions are used depending on the category of research:
- Research not involving greater than minimal risk to children: Where parental permission is to be obtained, the ACRE IRB may suggest that the permission of one (1) parent is sufficient for research not involving greater than minimal risk
- Research involving greater than minimal risk but presenting the prospect of direct benefit to the individual child: Where parental permission is to be obtained, the board may suggest that the permission of one (1) parent is sufficient for research involving greater than minimal risk but presenting the prospect of direct benefit to the individual participants
- Research involving greater than minimal risk and no prospect of direct benefit to the individual child, but likely to yield generalizable knowledge about the child’s disorder or condition: When the research is approved under this category, both parents must give their permission unless one (1) parent is deceased, unknown, incompetent, not reasonably available, or when only one (1) parent has legal responsibility for the care and custody of the child
If the ACRE IRB determines that a research study is designed for a participant population for which approval from the parents and/or legal guardian(s) or representative(s) is not reasonably required to protect the participants (e.g., neglected or abused children), the G-ACRE-IRB indicates that the consent requirements may be waived. In order to protect the rights and welfare of children in a research study, the board should consider the involvement of a court appointed guardian.
Assent Requirements
Per the LibCTReg, an assent form must be signed, and, if possible, dated by the minor. Similarly, per the G-LibClinTrial, when the research participant is a minor, the investigator must obtain assent from the child/minor. The G-NREB also indicates that both written parental consent and assent forms should be completed for children less than 18 years of age. Per LBR-34, the child’s assent should also be attained unless this can be justified by one (1) of the following reasons:
- The EC determined that assent of the child was not a requirement
- The capability of the child is so limited that the child cannot reasonably be consulted
According to LBR-34, the EC must approve the assent form, a witness must be present during the consent process, and the witness must sign and date the ICF.
In addition, the G-ACRE-IRB explains that adequate provisions for the assent of children include the following:
- Children capable of assenting: After the ACRE IRB determines that a child is capable of assenting, the proposed research procedures should be explained to the child in a language that is appropriate to the age, experience, maturity, and condition of the child and should include any discomforts and inconveniences the child may experience if the child agrees to participate in the study
- The option to withdraw: As they are in the developmental stage, children should be asked if they do or do not wish to participate in the research, especially where the research does not involve interventions likely to be of benefit to the participants but that they will be volunteers for the benefit of others
- The signing of assent or consent: When an assent requirement is established, the investigator or the designee and the child (when appropriate) will sign the study consent form. When it is inappropriate for the child to sign the form (due to age or ability), the board requires that the document be signed by the investigator (or the designee) and the parent/legal guardian
Per the G-ACRE-IRB, the ACRE IRB may determine that assent may be waived if the capability of some or all of the children is so limited that they cannot reasonably be consulted; or the intervention or procedure involved in the research has a direct benefit to the health or well-being of the children and is available only in the context of the research. In such instances, a child’s dissent which should normally be respected, may be overruled by the child’s parents at the discretion of the board (for example, when a research study involves providing experimental therapies for life-threatening diseases such as Ebola Virus Disease, severe COVID-19, or cancer, parents may wish to try anything to help their children, even with the likelihood of success being uncertain). If the child is a matured adolescent, the child’s wishes should be respected.
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 set forth in the LibCTReg and the G-LibClinTrial, the Liberia Medicines and Health Products Regulatory Authority (LMHRA) has adopted the International Council for Harmonisation's Guideline for Good Clinical Practice E6(R2) (LBR-8) for use along with the LMHRA guidelines.
As stated in the G-ACRE-IRB, for clinical research studies using the Atlantic Center for Research and Evaluation Institutional Review Board (ACRE IRB), pregnant women or fetuses may be involved in research if all the following conditions are met (Note: Per LBR-28, due to a Memorandum of Understanding (MOU) between the National Research Ethics Board of Liberia (NREB) and the ACRE IRB in 2022, the ACRE IRB does not review and approve clinical trial protocols. All clinical trial protocols submitted to the ACRE IRB are referred to the NREB.):
- Where scientifically appropriate, preclinical studies, including studies on pregnant animals, and clinical studies, including studies on non-pregnant women, have been conducted and provide data for assessing potential risks to pregnant women and fetuses
- The risk to the fetus is caused solely by the interventions or procedures considered directly beneficial for the woman or the fetus; or, if there is no such prospect of specific benefit, the risk to the fetus is not greater than minimal and the purpose of the research is for the development of important biomedical knowledge which cannot be obtained by any other means
- Any risk is the least possible for achieving the objectives of the research
- Consent is obtained in accordance with the informed consent provisions in the G-ACRE-IRB if the research holds out the prospect of direct benefit to a pregnant woman; the prospect of a direct benefit both to the pregnant woman and the fetus, or no prospect of benefit for the woman or the fetus when risk to the fetus is not greater than minimal; and the purpose of the research is the development of important biomedical knowledge that cannot be obtained by any other means
- If the research holds the prospect of direct benefit solely to the fetus, then the consent of the pregnant woman and the father is obtained in accordance with the informed consent provisions in the G-ACRE-IRB, except that the father’s consent need not be obtained if he is unable to consent due to unavailability, incompetence, or temporary incapacity, or, the pregnancy resulted from rape or incest (close relationship)
- Each person providing consent is fully informed regarding the foreseeable impact of the research on the fetus and/or resultant child
- For children who are pregnant, assent and permission are obtained in accordance with the provisions for children indicated in this guideline
- No inducements, monetary or otherwise, will be offered to terminate a pregnancy
- Individuals engaged in the research will have no part in any decisions as to the timing, method, or procedures used to terminate a pregnancy
- Individuals engaged in the research will have no part in determining the viability of a fetus
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
Pursuant to the G-ACRE-IRB, for clinical research studies using the Atlantic Center for Research and Evaluation Institutional Review Board (ACRE IRB), due to the vulnerability of prisoners, research involving prisoners should be reviewed by a fully convened ACRE IRB. (Note: Per LBR-28, due to a Memorandum of Understanding (MOU) between the National Research Ethics Board of Liberia (NREB) and the ACRE IRB in 2022, the ACRE IRB does not review and approve clinical trial protocols. All clinical trial protocols submitted to the ACRE IRB are referred to the NREB.) Per the G-ACRE-IRB, the ACRE IRB may only approve research projects involving prisoners if the research falls under one (1) of the following categories:
- Study of possible causes, effects, and processes of incarceration, and of criminal behavior, provided that the study presents no more than minimal risk or inconvenience to the participant
- Study of prisons as institutional structures or of prisoners as incarcerated persons, provided that the study presents no more than minimal risk and no more than inconvenience to the participants
- Research on conditions particularly affecting prisoners as a class (for example, vaccine trials and other research on Ebola, COVID-19, hepatitis, as well as social and psychological research such as alcoholism, drug addiction, and sexual assaults)
- Research on practices that are intended and have the probability of improving the health or well-being of the participants
In addition, per the G-ACRE-IRB, the ACRE IRB must review research involving prisoners and approve such research only if it finds that:
- The risks involved in the research are commensurate with risks that would be accepted by non-prisoner volunteers
- Procedures for the selection of participants within the prison are fair to all prisoners, and free of arbitrary interference by prison authorities or prisoners. Other than the investigator’s justification to the ACRE IRB, the use of other procedures, and the selection of control participants from the available prisoner population for a particular research study should be randomly done
- The information is presented in a language that is understandable to the participant population
- There is adequate assurance that parole boards will not take into account a prisoner’s participation, withdrawal, or lack of participation in the research in making decisions regarding parole, and each prisoner is clearly informed in advance that their participation, withdrawal, or lack of participation in the research will have no effect on his or her parole
- The ACRE IRB should ensure that adequate provisions are made where there will be a follow-up examination or care of participants after the end of their participation, considering the variable lengths of individual prisoners’ sentences, and informing participants of this information
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
As set forth in the LibCTReg, “persons under legal disability” is defined as being under the same category as a minor in terms of the individual’s ability to grant consent, except that the person under disability may be above the age of consent (18 years) even though the person may lack the mental capacity to reason properly and grant consent. In this case, priority is not given to parents or next of kin to petition the Probate Court for Guardianship, but priority is given to any natural person who demonstrates the best interest in the welfare of the disabled.
The LibCTReg further explains that a person under legal disability may participate in a trial, if their parents/legal guardians have be informed of the nature, significance, and implications of the clinical trial and have given a written voluntary informed consent. If the informed implication is grave, it may be necessary for the guardian to secure the permission from the Probate Court before granting consent, due to the fact that the Decree of Guardianship has a clause that the court-appointed guardian should not release the disabled person to any other body in which case their welfare will be put at peril. Otherwise, it can be argued that the appointed guardian has breached their fiduciary duty to the court by releasing the disabled person to peril.
Also, as indicated in LibCTReg, in the case of a clinical trial on a person of legal age who is incapable of comprehending the nature, significance, and implications of a clinical trial and of determining their will in the light of these facts, and who is also suffering from a disease which is to be treated by the investigational product (IP), the following conditions should be applied:
- The use of the IP must be indicated, according to the findings of medical science, in order to save the life of the trial participant, to restore the participant to health or to alleviate suffering
- The research must relate directly to a life-threatening or highly debilitating clinical condition suffered by the trial participant and the clinical trial may involve as little burden and other foreseeable risks as possible for the trial participant. Both the degree of burden and the risk threshold must be defined specifically in the trial protocol and monitored constantly by the investigator. The clinical trial may only be conducted if there is a justified expectation that the benefits of using the IP for the trial participant outweigh the risks
- Consent should be given by the legal representative/guardian after participant has been duly informed per the general clinical trial requirements in LibCTReg
- The research must be absolutely necessary for the confirmation of data obtained from clinical trials conducted on persons capable of granting informed consent or by means of other research methods
- With the exception of adequate compensation, no advantages may be granted
Additionally, as per the LibCTReg and the G-LibClinTrial, the Liberia Medicines and Health Products Regulatory Authority (LMHRA) has adopted the International Council for Harmonisation's Guideline for Good Clinical Practice E6(R2) (LBR-8) for use along with the LMHRA guidelines.
LBR-34 provides a sample National Research Ethics Board of Liberia (NREB) informed consent form (ICF) for adults unable to consent, which explains that the signature of the legally authorized representative documents their permission for the participant named in the ICF to take part in this research study, as well as their permission for the use and disclosure of the participant’s protected health information. The participant’s assent should also be attained unless this can be justified by one (1) of the following reasons:
- The EC determined that assent of the participant was not a requirement
- The capability of the participant is so limited that the participant cannot reasonably be consulted
The previously listed options are only available if they have been approved by the EC. A witness must also be present during the consent process and the witness must sign and date the ICF.
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
Per the LibCTReg and the G-LibClinTrial, the Liberia Medicines and Health Products Regulatory Authority (LMHRA) has adopted the International Council for Harmonisation's Guideline for Good Clinical Practice E6(R2) (LBR-8) for use along with the LMHRA guidelines.
As delineated in LibCTReg and LBR-8, an investigational 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. This 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, or when used to gain further information about an approved use. In Liberia, IPs are referred to as investigational medicinal products (IMPs).
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
As set forth in the LMHRA-Act, the Liberia Medicines and Health Products Regulatory Authority (LMHRA) is responsible for issuing licenses or permits for premises and personnel to engage in the manufacture of medicinal products in Liberia. The LibCTReg also states that investigational products (IPs) for clinical trials must be manufactured according to internationally accepted good manufacturing practice (GMP) principles.
Per the LibCTReg and the G-LibClinTrial, the LMHRA has also adopted the International Council for Harmonisation (ICH)'s Guideline for Good Clinical Practice E6(R2) (LBR-8) for use along with the LMHRA guidelines. LBR-8 notes that the sponsor should ensure an IP including the active comparator(s) and placebo, if applicable, is characterized as appropriate to the IP’s stage of development and is manufactured in accordance with applicable GMP. Per LBR-29, the World Health Organization’s (WHO) GMP Guidelines for IPs (LBR-26) and the International Council for Harmonisation (ICH) Harmonised Tripartite GMP Guide for Active Pharmaceutical Ingredients (LBR-9) must also be complied with during the IP manufacturing process.
As explained in G-Inspec-PMS, where pharmaceutical factories have not yet established validated manufacturing processes for pharmaceuticals for use in clinical trials, or have not yet established comprehensive manufacturing control standards, the factories must establish written operational procedures and keep detailed and accurate records for each batch of products manufactured, and each batch of raw material used. Batch manufacturing records must be kept until clinical trials are completed, or until at least two (2) years after the product is completed, whichever period is longer. Additionally, where pharmaceutical factories produce biopharmaceuticals or biotechnology products for use in clinical trials, impurities caused by virus inactivation/removal or other organisms may not exceed the limits imposed on other similar products on the market; where operational procedures for said products have not yet been validated, quality control tests must be performed.
Import
As set forth in the LMHRA-Act, the LMHRA is also responsible for issuing licenses or permits for the import/export of medicinal products in Liberia. Pursuant to the G-Inspec-PMS, authorization must be obtained from the LMHRA for the importation of medicines to be used in clinical trials. Per LBR-30, the Clinical Trials Unit within the LMHRA’s Pharmacovigilance & Clinical Trials Department is responsible for reviewing importation permits for IPs that are required for the conduct of clinical trials. Per LBR-5, the department is also responsible for receiving IP application submissions in Liberia and coordinating with the LMHRA’s Clinical Trial Team to ensure the safety and efficacy of the IPs to be used in clinical trials.
According to LBR-5, the IP dossier documentation requirements for the LMHRA’s approval are as follows:
- Submit typewritten application as per G-LibClinTrial
- Pay the required fee into the LMHRA bank account
- Submit payment slip to the Finance Department to obtain an official LMHRA receipt
- Present the IP dossier(s) along with the official receipt and product samples to the LMHRA
The G-LibClinTrial further explains that if the IP(s), health products, or any auxiliary medicinal product must be imported, the clinical trial must be approved by the LMHRA before the import can be authorized. IPs may only be imported if they are not locally available or if the need for importation is otherwise justified. The justification must be stated in the import permit application letter.
Per the LibCTReg and the G-LibClinTrial, the import permit application must contain the following information and documentation:
- Name and address of the sponsor, the sponsor’s legal representative, or the sponsor-investigator (both physical and postal)
- Principal investigator’s name, address (both physical and postal), and contact details (e.g., phone number and email)
- The clinical trial for which the application is made
- The planned clinical trial sites and the planned number of participants at the sites
- IP(s) description by name or code, strength, and dosage form
- IP(s) unit of issue, total quantity, batch number, manufacture, and expiry dates
- Sample labels of the primary and secondary containers
- Planned return of unused IP(s) to sponsor or destruction at the clinical trial site
The LibCTReg also notes that an application letter should be sent to the LMHRA Managing Director along with the required documentation.
In addition, per G-LibClinTrial, a parallel submission for approval of the clinical trial and the import permit application is possible. In this case, the import permit application can be included in the clinical trial application package.
Please note: Liberia is party to the Nagoya Protocol on Access and Benefit-sharing (LBR-3), 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 LBR-17.
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
Per the LibCTReg and the G-LibClinTrial, the Liberia Medicines and Health Products Regulatory Authority (LMHRA) has adopted the International Council for Harmonisation's Guideline for Good Clinical Practice E6(R2) (LBR-8) for use along with the LMHRA guidelines. Per the LBR-8, the sponsor should also update the investigator’s brochure (IB) as significant new information becomes available.
As specified in the LBR-8, the IB must provide coverage of the following areas:
- Physical, chemical, and pharmaceutical properties
- Pharmaceutical aspects
- Pharmacokinetics and metabolism
- Toxicological effects in any animal species tested under a single dose study, a repeated dose study, or a special study
- Results of clinical pharmacokinetic studies
- Information regarding safety, pharmacodynamics, efficacy, adverse events data, and dose responses obtained from prior clinical trials in humans
See the LBR-8 for additional details regarding the IB.
Quality Management
Per the G-LibClinTrial, the Good Manufacturing Practice (GMP) certificate issued from the national regulatory authority of the country where the investigational product (IP) is manufactured must be included in the clinical trial application submission package, if applicable. If necessary, the certificate must be translated to English.
According to LBR-29, the sponsor or the representative must also ensure that the products are manufactured in accordance with the WHO’s GMP Guidelines for Investigational Products (LBR-26) and the ICH Harmonised Tripartite Good Manufacturing Practice Guide for Active Pharmaceutical Ingredients (LBR-9).
Per LBR-8, the sponsor must maintain a Certificate of Analysis to document the identity, purity, and strength of the IP(s) to be used in the clinical trial.
(See Product Management section for additional information on sponsor 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 Liberia must comply with the requirements set forth in the LibCTReg, the G-LibClinTrial, and the G-Inspec-PMS. While there is no specified language requirement for IP labeling, English appears to be the preferred language. (Note: IPs are also referred to as investigational medicinal products (IMPs)). Per the LibCTReg and the G-LibClinTrial, the Liberia Medicines and Health Products Regulatory Authority (LMHRA) has adopted the International Council for Harmonisation's Guideline for Good Clinical Practice E6(R2) (LBR-8) for use along with the LMHRA guidelines.
The LibCTReg specifies that IPs to be used in a clinical trial center must be properly labelled and the package must sufficiently identify the following:
- The clinical trial to be carried out
- The medicine(s) to be used
- The trial participant identification number to whom the medicine is to be administered
- The name and address of the site where the clinical trial is conducted
- The directions in regard to the manner in which such medicine should be used
- The date of dispensing, if applicable
- The storage conditions
- The use-by, expiry, or re-test date, as applicable
- The reference number, as applicable
- Any other information as may be required by the LMHRA
As delineated in the G-LibClinTrial, if the primary container takes the form of blister packs or small units such as ampoules, the secondary packaging should be provided bearing a label with the required particulars. However, the primary container should bear the following information:
- Name of the sponsor, contract research organization (CRO), or investigator
- Route of administration (may be excluded for oral solid dosage forms) and in the case of open trials, the name/identifier of the IP and strength/potency
- 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
In addition, the G-LibClinTrial explains that if it becomes necessary to change the expiry/use-by date, an additional label should be affixed to the IP which should state the new use-by date and repeat the batch number. It may be superimposed on the old date, but for quality control reasons, not on the original batch number. The operation should be performed at an appropriately authorized manufacturing site. However, when justified, the operation may be performed at the investigational site by or under the supervision of the clinical trial site pharmacist (if available), the principal investigator, or the clinical trial monitor(s), who should be appropriately trained. The provisions listed above may apply for auxiliary medicinal products. An auxiliary medicinal product is a medicinal product used for the needs of a clinical trial as described in the protocol, but not as an IP (e.g., medicinal products used as rescue medication, challenge agents, to assess endpoints in the clinical trial, or background treatment).
As explained in the G-Inspec-PMS, where pharmaceutical factories produce pharmaceuticals for use in clinical trials, the IPs must also be labeled “for use in clinical trials only” and marked with the name of the party that commissioned the clinical trial and a trial code sufficient to identify the trial location and the research personnel involved. However, where pharmaceuticals for use in clinical trials are tested in closed trials (double-blind trials), drug name, potency, and efficacy may be replaced by product codes, serial numbers, and packaging batch numbers.
LBR-8 states that the IP must be coded and labeled in a manner that protects the blinding, if applicable, and comply with applicable regulatory requirements. The IPs must also be suitably packaged in a manner that will prevent contamination and unacceptable deterioration during transport and storage.
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
Per the LibCTReg and the G-LibClinTrial, the Liberia Medicines and Health Products Regulatory Authority (LMHRA) has adopted the International Council for Harmonisation (ICH)'s Guideline for Good Clinical Practice E6(R2) (LBR-8) for use along with the LMHRA guidelines. According to LBR-29, the World Health Organization's (WHO) Good Manufacturing Practice (GMP) Guidelines for Investigational Products (IPs) (LBR-26) and the ICH Harmonised Tripartite Good Manufacturing Practice Guide for Active Pharmaceutical Ingredients (LBR-9) must also be complied with during IP product management. In addition, per the LMHRA-Act, the LMHRA is responsible for the supply and storage of medicinal products in Liberia. See LBR-26 and LBR-9 for details.
The LibCTReg specifies that it is the responsibility of the sponsor to supply IPs (also referred to as investigational medicinal products (IMPs)) produced in compliance with internationally accepted GMP principles. According to LBR-8, the sponsor or the representative must also supply the investigator(s)/institution(s) with the IPs. The sponsor or the representative should not supply either party with the IP(s) until all the required documentation is obtained. In this case, per the LMHRA-Act, the LMHRA approval license/permit is the required documentation. Per LBR-8, the IPs should be manufactured, handled, and stored in accordance with applicable GMP and the sponsor must ensure that the written procedures include instructions that the investigator/institution should follow for the handling and storage of IP(s) for the trial and documentation thereof. The procedures should address adequate and safe receipt, handling, storage, dispensing, retrieval of unused product from participants, and return of unused IP(s) to the sponsor (or alternative disposition if authorized by the sponsor and in compliance with the applicable regulatory requirement(s)). The sponsor must also ensure the timely delivery of the IP(s).
LBR-8 specifies that the sponsor should determine acceptable storage temperatures, storage conditions (e.g., protection from light), storage times, reconstitution fluids and procedures, and devices for product infusion for the IPs, if any. The sponsor should inform all involved parties (e.g., monitors, investigators, pharmacists, storage managers) of these determinations. Further, the sponsor should also take steps to ensure that the IPs are stable for the period of use and maintain sufficient quantities of IPs to reconfirm specifications, and if necessary, maintain records of batch sample analyses and characteristics. To the extent stability permits, samples should be retained either until the trial data analyses are complete, or as required by the applicable regulatory requirements, whichever represents the longer retention period. Refer to LBR-8 for detailed, sponsor-related IP requirements.
The LibCTReg further specifies that destruction operations for IPs should be carried out in such a manner that all operations may be accounted for. Documentation should clearly identify, or allow traceability to, the batches and/or trial participant numbers involved and the actual quantities destroyed. The G-LibClinTrial also states that if the IP(s), health product(s), or auxiliary medicine(s) used in a clinical trial are to be destroyed at any point in time, a respective destruction procedure must be provided to the LMHRA as part of the clinical trial protocol. The sponsor or the contract research organization (CRO) must bear the cost of the disposal.
As per the LibCTReg, if the sponsor or sponsor-investigator would like to export the IP(s) remaining after the clinical trial has been stopped or completed, the sponsor, the legal representative, or the sponsor-investigator must obtain an export authorization from the LMHRA.
Per the G-Inspec-PMS, pharmaceutical factories must determine a suitable expiration date for pharmaceuticals for use in clinical trials based on the product properties, container characteristics, and storage conditions. See the G-Inspec-PMS for additional information.
Record Requirements
Per LBR-8, the sponsor must ensure the following:
- Maintain records that document IP(s) shipment, receipt, disposition, return, and destruction
- Maintain a system for retrieving IPs and documenting this retrieval
- Maintain a system for the disposition of unused IP(s) and for the documentation of this disposition
LBR-8 also specifies that the investigator/institution and/or a pharmacist, or other appropriate individual who is designated by the investigator/institution, should maintain records of the IP's delivery to the trial site, the inventory at the site, the use by each participant, and the return to the sponsor or alternative disposition of unused product(s). These records should include dates, quantities, batch/serial numbers, expiration dates (if applicable), and the unique code numbers assigned to the IP(s) and trial participants. Investigators should maintain records that document adequately that the participants were provided the doses specified by the protocol and reconcile all IP(s) received from the sponsor.
In addition, per LBR-8, sponsor-specific essential documents should also be retained until at least two (2) years after the last approval of a marketing application, until there are no pending or contemplated marketing applications, or at least two (2) years have elapsed since the formal discontinuation of the IP’s clinical development.
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 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.
While the Liberia Medicines and Health Products Regulatory Authority (LMHRA) does not provide a formal definition for specimens, the Atlantic Center for Research and Evaluation Institutional Review Board (ACRE IRB) describes examples of specimens in the G-ACRE-IRB. As per the G-ACRE-IRB, examples of biological specimens include:
- Collection of blood via finger or ear stick
- Hair and nail clippings collected in a non-disfiguring manner
- Excreta and external secretions (including sweat)
- Sputum collected through expectoration
- Bodily fluids
- Tissue biopsies
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
Information is unavailable regarding the Liberia Medicines and Health Products Regulatory Authority (LMHRA)’s role in approving the import of biological specimens.
Export
As set forth in the LibCTReg and the G-LibClinTrial, the applicant must obtain an authorization from the LMHRA if biological samples are to be exported out of Liberia. Additionally, per the LibCTReg and G-LibClinTrial, the applicant must provide an annual progress report on the use and results obtained from the biological samples exported out of Liberia. Pursuant to Part VIII of the LMHRA-Act, the LibCTReg also states that any person(s), institution(s), corporate entity(ies), their designees or legal representatives who is found in violation of any provision of the biological sample export requirements delineated in LibCTReg will be liable to fines as prescribed by the LMHRA at the time of commission.
Material Transfer Agreement
Per the LibCTReg and the G-LibClinTrial, a material transfer agreement (MTA) must also be provided to the LMHRA. The G-LibClinTrial notes that the authorization request and the MTA should be included in the clinical trial application submission package.
The G-NREB indicates that the National Research Ethics Board of Liberia (NREB) requires the MTA process be used for the shipment of specimens/biological materials outside of Liberia. The G-NREB also specifies that when a protocol application is submitted for review by the NREB, the accompanying documentation should also include an MTA for the shipment of the specimen/biological materials outside of Liberia (where applicable).
According to the G-ACRE-IRB, the Atlantic Center for Research and Evaluation Institutional Review Board (ACRE IRB) requires the MTA process be used for the shipment of specimens/biological materials outside of Liberia. The G-ACRE-IRB further explains that the purpose of an MTA is to protect the interests of local researchers and Liberia’s human and natural resources in all its biodiversity and how they can be legitimately used. It ensures that the interests of all relevant parties are protected from exploitation and egregious harm. (Note: Per LBR-28, due to a Memorandum of Understanding (MOU) between the NREB and the ACRE IRB in 2022, the ACRE IRB does not review and approve clinical trial protocols. All clinical trial protocols submitted to the ACRE IRB are referred to the NREB.)
Per the G-ACRE-IRB, for studies using the ACRE IRB, the MTA must detail the type of materials, anticipated use, location of storage outside Liberia, duration of such storage, and limitations on use, transfer, and termination of use of such materials subject to any laws, regulations, and enactments in Liberia.
In addition, per the G-ACRE-IRB, the ACRE IRB requires an MTA be signed by all parties involved in the research including local and international principal investigators, heads of local institutions, research sponsors, and other relevant entities prior to the transfer or export of biological samples out of Liberia. The MTA must detail the type of materials, anticipated use, location of storage outside Liberia, duration of such storage, limitations on use, transfer, and termination of use of such materials, subject to any laws, regulations, and enactments in Liberia. The following requirements must also be met:
- The ACRE IRB (the provider institution) must review the MTA to ensure consistency with the stated objectives of the research, the contents of the informed consent documents, and the principles stated in the G-ACRE-IRB. The ACRE IRB must grant provisional approval pending the submission of the MTA to the ethics committee (EC) (the recipient institution) and the EC’s receipt of acknowledgement
- The applicant for research review (the scientist or sponsor at the provider institution) must file a copy of the MTA and provisional approval by the ACRE IRB (the provider institution) with the EC (the recipient institution) for record purposes only
- The EC (the recipient institution) must acknowledge receipt of the MTA to the applicant (the scientist or sponsor at the provider institution) who must inform the ACRE IRB (the provider institution)
- The ACRE IRB (the provider institution) is required to grant final approval to research involving international transfer of Liberian samples after all the other stated criteria have been met and upon acknowledgement of MTA receipt
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
Detailed information is unavailable regarding the Liberia Medicines and Health Products Regulatory Authority (LMHRA)’s requirements for obtaining informed consent from participants prior to collecting, storing, or using their biological sample(s). Additionally, no applicable requirements are available regarding the National Research Ethics Board of Liberia (NREB)’s requirements for obtaining participant informed consent prior to collecting, storing, or using their biological sample(s).
However, the G-ACRE-IRB notes that for studies using the Atlantic Center for Research and Evaluation Institutional Review Board (ACRE IRB), the Material Transfer Agreement (MTA) does not invalidate the right of research participants or communities to request that their samples be withdrawn from research according to the terms of the informed consent process. (Note: Per LBR-28, due to a Memorandum of Understanding (MOU) between the NREB and the ACRE IRB in 2022, the ACRE IRB does not review and approve clinical trial protocols. All clinical trial protocols submitted to the ACRE IRB are referred to the NREB.)
As delineated in the G-ACRE-IRB, the following information must be provided for the ACRE IRB’s review of a research protocol involving specimens:
- A full description of any specimens that will be collected (blood, bodily fluids, tissue biopsies, etc.)
- Plans for obtaining consent and clearance from participants and the ACRE IRB, for long-term storage, export, and future research
- Arrangements for transfer and disposal
- Community considerations
- The impact and relevance of the research on the local community from where the research participants are recruited as well as the wider communities and the environment of concern
- The consultation procedures with the concerned communities at the time of the planning and designing of the research
- The influence of the community on the consent of the research participants/individuals
- Proposed community consultation during the course of the research
- The extent to which the research contributes to capacity-building, such as the improvement of local healthcare, research, and the ability to respond to public health needs
- Description of how the research results will be made available to the research participants and the concerned communities
Pursuant to the G-ACRE-IRB, for research that involves the collection of identifiable private information or identifiable biospecimens, one (1) of the following must be included in the informed consent:
- A statement that identifiers will be removed from the identifiable private information or identifiable biospecimens and that, after such removal, the information or biospecimens could be used for future research studies without additional informed consent from the participant or legal representative/guardian; or
- A statement that the participant's information or biospecimens collected as part of the research, even if identifiers are removed, will not be used or distributed for future research studies
See the Required Elements and Participant Rights sections for additional information on informed consent.
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.
