Post-Approval Studies (PAS) Database

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.

Detailed Study Protocol Parameters
Study Objectives Objectives: to evaluate post-market safety and effectiveness of the GORE Viabahn endoprosthesis for treatment of ISR of the SFA.

Study design: a prospective, non-randomized, multicenter, single-arm observational study involving a minimum of 108 newly enrolled subjects.
Study Population Subjects presenting with symptomatic peripheral artery disease (Rutherford Category 2-5) with occlusive lesion(s) within and adjacent to previously implanted non-covered stent(s) located in the SFA.
Sample Size A total of 108 subjects, comprising of a minimum of 81 subjects in the US and maximum of 27 OUS subjects will be enrolled from 15 US and 5 OUS sites. The study population will include a minimum of 20 subjects with ISR lesion length 230- 270mm.
The sample size of 108 subjects is expected to yield an evaluable sample size of 86 subjects at 1-year after 20% lost to follow-up.
Key Study Endpoints Primary Effectiveness Endpoint: Primary Patency at 12 months
Primary Safety Endpoint:
Device- and procedure-related SAEs within 30 days of the index procedure

Secondary Endpoint:
Acute Procedural Success
Secondary endpoint to be evaluated at 30 days, 12, 24 and
36 months include: Primary Patency
Primary Assisted Patency
Secondary Patency
Freedom from Target Lesion Revascularization (TLR) Freedom from Major Amputation
Change in Ankle-Brachial Index from pre-procedure Change in Rutherford Category from pre-procedure Adverse Event Report
Stent Fracture Assessment at 12, 24 and 36 months by the Core Lab
Follow-up Visits and Length of Follow-up 3 years
30 days, 1, 2 and 3 years
Interim or Final Data Summary
Actual Number of Patients Enrolled 108
Actual Number of Sites Enrolled 23
Patient Follow-up Rate 30 day visit: 101 out of 108 (93.5%)
12-month visit: 78 out of 95 (82.1%)
2-year follow-up visit: 61 out of 73 (83.6%)
3- year follow-up visit: 53 out of 61 (86.9%)
Final Safety Findings SAE events were reported within 30 days: Three (2.8%; sepsis, retroperitoneal bleed, groin hematoma)
Free from SAE within 30 days: 105 (97.2%)
Final Effect Findings Primary patency at 12-months for the intent-to-treat subject cohort is 71.5% (Kaplan-Meier Estimates 95% Confidence Interval: 60.7%, 79.7%).
30 days: 99.0%
12 months: 71.5%
24 months: 56.1%
36 months: 44.9 %
Study Strengths & Weaknesses The follow-up compliance and study deviations were within reasonable expectations.
Recommendations for Labeling Changes Additional information is available from these results that supplements information already contained in the publicly available SSED and labeling. Therefore, labeling changes are recommended.
