Qualified Clinical Outcome Assessments (COA)

The table below lists qualified Clinical Outcome Assessments (COA). The tables include legacy projects (those submitted prior to passage of the 21st Century Cures Act), as well as those submitted as part of the newer section 507 process (referring to section 507 of the Federal Food, Drug and Cosmetic Act (FD&C Act)), which was created by Section 3011 of the 21st Century Cures Act). The tables are updated on a biannual basis and provide information on the COA qualification project, qualification statement, and supporting information. Additionally, the table includes documents from requestors that were received after the passage of the 21st Century Cures Act.

FDA’s posting of information submitted to the agency by outside parties requesting qualification of a drug development tool is not an endorsement or recommendation by FDA. Information about submissions are made publicly available in accordance with section 507 of the FD&C Act. FDA makes no representations, guarantees, or warranties as to the accuracy, completeness, currency, or suitability of the information about submissions. See the FDA decision letter corresponding to each submission for FDA considerations and recommendations related to each request for qualification.
