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 Status Completed
Application Number P000040 S014/ PAS001
Date Current Protocol Accepted 04/23/2012
Study Name Genesys HTA Post Approval Registry
General Study Protocol Parameters
Study Design Prospective Cohort Study
Data Source Sponsor Registry
Comparison Group No Control
Analysis Type Analytical
Study Population Adult: >21
Detailed Study Protocol Parameters
Study Design Description A Multi-center, Single-arm, Prospective Registry of the Genesys HTATM System for the Treatment of Menorrhagia will evaluate safety and technical performance of the device at time of treatment.
Study Population Description All women treated with the Genesys HTATM System under the approved indications for use who agree to participate
Sample Size 1312 subjects at a maximum of 100 clinical sites
Data Collection Rate of clinically significant burns (primary)

Rate of technical complaints with the system (secondary)

Assessment of serious adverse events (secondary)
Interim or Final Data Summary
Actual Number of Patients Enrolled 1,014
Actual Number of Sites Enrolled 18
Patient Follow-up Rate 91.8% (931/1,014)
Final Safety Findings There have been 4 burn events: 3 non-clinically significant burns and 1 clinically significant burn were reported. The rate of this clinically significant event was 0.1% (95% CI 0.0%, 0.6%). The primary hypothesis of the PAS is that the subject rate of clinically significant burns is not significantly greater than 1.0%.

For the secondary endpoint, there has been one (1) Serious Adverse Device Effect. This was a superficial 2nd degree burn for a subject for a rate of 0.1% (95% CI: 0.0% ¿ 0.6%).

Final Effect Findings There was no effectiveness endpoint per se. The secondary objective of the study was to obtain data on technical problems with the device. Fifty-three (53) technical complaints were reported for 44 subjects in the intent-to-treat population (N=992). Therefore, the rate of technical complaints per subject was 5.3% (53/992).
Study Strengths & Weaknesses This study had an adequate sample size that was large enough to study key safety issues.
Recommendations for Labeling Changes No labeling changes are recommended
