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 EVOLVE Short DAPT clinical trial is a prospective, multicenter, single-arm study designed to assess the safety of 3-month dual antiplatelet therapy (DAPT) in subjects at high risk for bleeding undergoing percutaneous coronary intervention (PCI) with the SYNERGY¿ Everolimus-Eluting Platinum Chromium Coronary Stent System (SYNERGY Stent System).
Study Population Description Device:

Subject considered at high risk for bleeding, defined as meeting one or more of the following criteria at the time of enrollment: ≥75 years of age, current anticoagulation therapy, history of major bleeding, stroke, or renal insufficiency (creatinine ≥2.0 mg/dl) or renal failure (dialysis dependent).


Historical data collected from subjects at high risk for bleeding receiving 12 months of DAPT

Sample Size 2,000 subjects will be enrolled in up to 110 sites worldwide in the United States, Europe, Japan, and Brazil.

Number of evaluable test subjects required in the propensity score model is 1,650 (1,500 *1.1) including additional 10% subjects accounting for model variability

Expected drop out rate due to ineligibility for 3 month DAPT in 0 to 3 months = 15%

Expected attrition rate in 3 to 15 months = 3%

Data Collection Primary endpoint: Rate of death or MI between 3 and 15 months post-index procedure

Powered major secondary endpoints:

¿ Rate of ARC definite/probable stent thrombosis (ST) involving the SYNERGY stent between 3 and 15 months post-index procedure

¿ Rate of major bleeding (GUSTO severe/life-threatening + moderate) between 3 and 15 month post-index procedure

Follow-up Visits and Length of Follow-up All enrolled subjects are to be followed through 15 months after the index procedure. The study will be considered complete with regard to the primary endpoint after all subjects have completed 15-months follow-up.
