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.

Final Safety Findings Re-treatment with Belotero Balance did not result in an increase in ¿severe¿ adverse events (AEs). Total percentage subjects with severe ¿common¿ AEs was 15.6% after the initial treatment, during the pre-approval study, and 7.7% with re-treatment during the post-approval study (p<0.0085). Specifically, the incidence rates of severe adverse events after re-treatment were 11.5% and 5.4% for subjects with Fitzpatrick Skin Type Grades I-III and Grades IV-VI respectively. The duration of ¿severe¿ adverse events with re-treatment was generally short (mean 10.2 days, SD = 5.6, 95% CI = 8.2, 12.2) and none of these events required treatment.
Final Effect Findings No effectiveness endpoints were included in the study.
Study Strengths & Weaknesses The post-approval study sample size was 117 exceeding the minimum requirement of 104 subjects. A total of 113 re-treated subjects completed the study achieving a 97% follow-up rate. Adverse events occurring beyond one month after re-treatment were not captured because the length of follow-up was restricted to one month.
Recommendations for Labeling Changes Labeling changes are recommended to reflect severe adverse event incidence rates after re- treatment.
