Post-Approval Studies Program

The FDA may require a post-approval study (or studies) at the time of approval of a Premarket  Approval (PMA), Humanitarian Device Exemption (HDE), or product development protocol (PDP) application to help assure continued safety and effectiveness (or continued probable benefit, in the case of an HDE) of the approved device.  

Post-approval studies are conditions of device approval. A sponsor’s failure to comply with any post-approval requirement may be grounds for the FDA to withdraw approval. (Note: A device may have more than one post-approval study imposed by a PMA, HDE, or PDP application.)

The FDA's Post-Approval Studies Program ensures that methodologies are well-designed and conducted effectively, efficiently and in the least burdensome manner.

  • Applicant’s Reporting Status in the database is listed as Sponsor’s Reporting Status in the guidance.

Updates to Study Information in the Database

The FDA updates the database every Sunday with any new or revised information on study protocol parameters (for example, patient population), overall study status, or information related to the review of data from interim or final reports.

Obtaining PMA Approval Letters, PAS Protocols, or PAS Final Reports 

The Premarket Approval (PMA) for a device includes the order for post-approval studies, as well as the Summary of Safety and Effectiveness Data (SSED). To access the approval letter, go to the Premarket Approval (PMA) database.
