The National Institute of Allergy and Infectious Diseases (NIAID)’s ClinRegs website is an online database of country-specific, clinical research regulatory information. By providing well-documented and current information in a single place, ClinRegs serves as a central resource and time-saver for persons involved in planning and implementing international clinical research.

Information Available

Countries and topics are included based on NIAID’s international clinical research priorities.

Country-specific regulatory information is organized by the following topic areas:

  • Regulatory Authority
  • Ethics Committee
  • Clinical Trial Lifecycle
  • Sponsorship
  • Informed Consent
  • Investigational Products
  • Specimens

The single-country profile view provides a summary of the requirements for each topic section. Cited sources are accessible by clicking on the source links.

The comparison view provides a side-by-side view of the topic summaries for up to four countries. Cited sources are accessible by clicking on the source links.

When available, ClinRegs provides English versions of regulatory documents. English translations from sources other than a regulatory authority are designated “unofficial.” When more than one language is available, you can select from the hyperlinked options. For certain non-English sources, links to online machine translations, such as Google translations, are provided. These links are for information purposes only and may not always work as expected. ClinRegs does not control the quality or accuracy of translated content. If you require assistance locating specific regulatory information or have questions about the site, then contact the ClinRegs team by clicking the Contact Us link at the top of each page.

Content Development and Maintenance

The ClinRegs team—comprised of regulatory, legal, and policy analysis experts—reviews and analyzes regulatory authority information to develop the website content. To ensure fidelity, accuracy, and consistency, all content is vetted by country-specific subject matter experts and edited for clarity and style. See the Acknowledgements page for a list of the country experts.

On average, country content is reviewed and, if necessary, updated yearly. However, updates may be issued more frequently, particularly to incorporate substantial, timely changes to country regulations or requirements. We welcome you to share your expertise via the comment button on the right side of the page, or via the Contact Us link at the top of each page.

Broken links are identified and fixed monthly.


ClinRegs is a NIAID Executive Committee-approved project developed under NIAID’s Barriers to Clinical Research initiative. Management responsibility for ClinRegs resides principally in the Division of Clinical Research (DCR) with guidance from the ClinRegs Steering Group (ClinRegs SG), a subcommittee of the NIAID Clinical Research Subcommittee. Comprised of NIAID divisional representatives with expertise in international clinical research, ClinRegs SG members are responsible for providing input, guidance, and prioritization for the site’s content, features, and functionality based on the interests, needs, and preferences of their respective NIAID divisions. The ClinRegs SG also serves as the site’s change control board.
