Background: While extended dual antiplatelet therapy (DAPT) with aspirin and a platelet (P2Y12) inhibitor after percutaneous coronary intervention (PCI) reduces the risk of stent thrombosis (ST) and myocardial infarction (MI), it also increases bleeding. Newer generation drug-eluting stents with bioabsorbable polymer coatings may reduce thrombotic events and allow abbreviated DAPT in selected patients. The EVOLVE Short DAPT study is designed to evaluate the safety of 3-month DAPT in high bleeding risk subjects treated with the SYNERGY bioabsorbable polymer everolimus-eluting stent.

Trial design: EVOLVE Short DAPT is a prospective, single-arm, international study that enrolled 2009 high risk bleeding subjects (defined as age ≥75 years, chronic anticoagulation, major bleeding within 12 months, history of stroke, renal insufficiency/failure, or thrombocytopenia) who underwent PCI with the SYNERGY stent. Subjects presenting with acute MI or complex lesions were excluded. After 3 months treatment with DAPT (except those on anticoagulant in whom aspirin is optional), subjects free from stroke, MI, revascularization or ST will be eligible to discontinue P2Y12 inhibitor, but continue aspirin. Co-primary endpoints assessed between 3-15 months are: i) death/MI compared for non-inferiority with propensity-adjusted historical group receiving 12-month DAPT, and ii) definite/probable ST compared to a performance goal. The secondary endpoint is the rate of bleeding in subjects not receiving chronic anticoagulation compared for superiority against a propensity-adjusted historical control.

Conclusion: The EVOLVE Short DAPT study will prospectively define the safety of DAPT discontinuation at 3 months in high bleeding risk patients treated with the SYNERGY stent.
