Post-Approval Studies (PAS) Database

  • E-mail

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 Design Description The purpose of this study is to collect long term safety data of Optisure family of high voltage leads. This study transitions the

Optisure Post Approval Study from a traditional prospective study design to a real world evidence data method for post market

monitoring of the Optisure lead. This method merges multiple real world datasets to assess the Optisure lead performance in a larger

patient population. The proposed method matches patient population datasets from Abbott and Centers for Medicare and

Medicaid Services (CMS) in order to generate data that can be used to evaluate safety of leads in a post market setting.
Study Population Description All patients who had an implant of the Optisure Lead, meet inclusion/exclusion criteria, and link to Medicare FFS claims will be

included in the analysis of this endpoint.
Sample Size Assuming the time to first complication follows an exponential distribution and the complication-free survival at 5 years is 95%, a

minimal sample size of 645 patients provides 80% power to reject the null hypothesis of 92.5% complication-free survival years at the 5%

significance level.

It is estimated that 4287 patients with Optisure lead implants will meet inclusion/exclusion criteria and link to Medicare FFS claims for this

study, which greatly exceeds the minimal required sample size.
Data Collection The primary outcome measure is the complication free survival rate at five years for complications related to the Otisure leads.

The secondary outcome measure is a rate of cardiac tamponade or cardiac perforation events.
Follow-up Visits and Length of Follow-up The study completion is 5 years after final implant, December 2020. The data retention period will be for 2 years after the submission of the final report.
