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.

Interim or Final Data Summary
Actual Number of Patients Enrolled 100
Actual Number of Sites Enrolled 7
Patient Follow-up Rate 95%
Final Safety Findings No significant safety problems were reported at 36 months. A clinically significant decrease in systolic blood pressure was sustained for 36 months.
Final Effect Findings The rate of the primary endpoint was 91.7% and the lower limit of the 95% two-sided confidence interval was 84.2%. The primary premarket hypothesis tested was the 9-month primary patency rate that resulted greater than 60% (p < 0.001). Therefore, the rate was higher than the performance goal. Technical Success was 97.4% (112/115) on a per lesion basis.
Study Strengths & Weaknesses Results provide further evidence of the clinical utility and safety of this device.
Recommendations for Labeling Changes Post-approval study findings should be part of the device labeling, including the following key safety findings: the 9-month primary patency rate (table 3.10-1), Major Adverse Events (table 3.11.1-1), technical success, acute procedural success (tables 3.11.2-1 and3.11.3-1), blood pressure results (table3.11.6.1-1) cured and improved hypertension at 36 months (table 3.11.6.3-
1) and renal function results (tables 3.11.7-1 and 3.11.7-2).
