The FDA has the authority to require sponsors to perform 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. Post-approval studies can provide patients, health care professionals, the device industry, the FDA and other stakeholders information on the continued safety and effectiveness (or continued probable benefit, in the case of an HDE) of approved medical devices. This database allows you to search Post-Approval Study information by applicant or device information.

Study Strengths & Weaknesses This enhanced surveillance requirement was designed to collect data for two years of commercial experience, in order to characterize adverse events from a real world setting. There was no pre-specified sample size, and only 17 patients were enrolled out of 47 patients who received commercial treatments at the participating study sites.

Recommendations for Labeling Changes Due to the low sample size and study limitations, no labeling change is recommended.
