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) approved medical devices. This database allows you to search Post-Approval Study information by applicant or device information.

Detailed Study Protocol Parameters
Study Design Description New enrollment study designed to evaluate the safety and effectiveness of

Lap-Band. Prospective single-arm cohort.

Study Population Description Patients with BMI >=30 kg/m2 and <40 kg/m2 and 1 or more obesity-

related comorbidities. There is no control group in this study.

Sample Size 325 subjects will be enrolled across 20 U.S. sites. Assuming 20% attrition, a sample size of 260 subjects at 5 years provides 84% power to test the hypothesis that the reduction in diabetes prevalence at 5 years will be at least 5%. This will be tested using a 1-sided exact binomial test with a 5% significance level. Up to 65 subjects can be enrolled per site.

Data Collection Primary safety endpoint: 5-year explant rate; Secondary effectiveness

endpoints: 5-year responder rate (where response is defined as achieving >=

7% TBL), diabetes prevalence at 5 years, and change in obesity-related comorbidities at 5 years compared to baseline

Follow-up Visits and Length of Follow-up 10 Years - In-office visits before and after surgery, at 1, 2, 3, and 6 months, and 1, 3, 5,

7, and 10 years after surgery. Patients will complete a questionnaire at 2, 4,

6, 8, and 9 years after surgery.
