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 Population Description Patients treated with the BethCath 3.5F System. These patients receive beta radiation to the site of successful percutaneous coronary intervention for the treatment of in-stent restenosis in native coronary arteries with discrete lesions in a reference vessel diameter ranging from 2.7 to 4.0 mm.
Sample Size 200 patients, 1 site
Data Collection The primary safety endpoints are: (1) Incidence of device related procedural events and (2) major adverse events at each study point. The primary efficacy endpoints are: 1) device success including successful delivery of source train, return of source train and delivery of intended dose and 2) target vessel revascularization.
Follow-up Visits and Length of Follow-up Patients will be followed clinically at 6 months, 1, 2, 3, 4, and 5 years post treatment. Due to retrospective enrollment, patients may be enrolled at any of the specified time points and followed for subsequent visits.
