Brief Summary
Patients undergoing the percutaneous coronary intervention (PCI) for in-stent restenosis (ISR) are enrolled. All patients will be randomized to receive either 12 months or 24 months of dual antiplatelet therapy with a P2Y12 receptor antagonist in addition to aspirin, all patients continue receiving aspirin indefinitely. The primary efficacy end points of this study are the incidence of a composite end point including all cause deaths, myocardial infarction, the incidence of Academic Research Consortium defined definite or probable stent thrombosis and stroke (MACCE) at 24 months. The primary safety end point is the incidence of GUSTO moderate or severe bleeding.

Study Arms (2)
24 months of P2Y12 receptor antagonist
ACTIVE COMPARATORReceive 24 months of dual antiplatelet therapy (with a P2Y12 receptor antagonist in addition to aspirin) after index procedure. All subjects receive aspirin for the duration of study.
12 months of P2Y12 receptor antagonist
PLACEBO COMPARATORReceive 12 months of dual antiplatelet therapy (with a P2Y12 receptor antagonist in addition to aspirin) after index procedure. All subjects receive aspirin for the duration of study.
Interventions
All subjects will be received 12 months of dual antiplatelet therapy with a P2Y12 receptor antagonist (clopidogrel/prasugrel/ticagrelor) in addition to aspirin.
All subjects will be received 24 months of dual antiplatelet therapy with a P2Y12 receptor antagonist (clopidogrel/prasugrel/ticagrelor) in addition to aspirin.
The maintenance dose of aspirin is 100 mg daily, to be taken indefinitely.
