Study Summary

This study is a prospective, open-label, multicenter, randomized clinical trial to evaluate the efficacy of 1 month dual antiplatelet therapy (DAPT) with aspirin plus clopidogrel followed by clopidogrel monotherapy, compared with 12 months DAPT with aspirin plus clopidogrel in patients undergoing percutaneous coronary intervention with Genoss® drug eluting stents.

Eligibility Criteria

Inclusion

Inclusion Criteria:

  • Subjects must be at least 19 years of age
  • Subjects undergoing elective PCI with Genoss® Drug Eluting Stents
  • Subject who can understand the risk, benefit and treatment alternatives, and whenhe/she or his/her legally authorized representative provides written informed consentprior to any study related procedure

Exclusion

Exclusion Criteria:

  • Subjects presenting with acute myocardial infarction
  • Subjects with less than 1 year of life expectancy
  • Subjects presenting with cardiogenic shock
  • Subjects requiring anticoagulation (warfarin, direct oral anticoagulant), or thoserequiring antiplatelet agents other than aspirin and P2Y12 inhibitors.
  • Subjects with history of intracranial hemorrhage (ICH)
  • Known hypersensitivity or contraindications to study medications (aspirin,clopidogrel), or drugs used in the procedure (heparin, contrast media, sirolimus).Those with contrast hypersensitivity can be enrolled if symptom/signs can becontrolled by anti-histamines or steroids.

Study Description

Dual antiplatelet therapy (DAPT) with aspirin and a P2Y12 inhibitor is recommended following percutaneous coronary intervention (PCI). However, the optimal duration of DAPT is still controversial, and current US and European guidelines recommend 12+ months for Acute Coronary Syndrome (ACS) and 6+ months in Chronic Coronary Syndrome (CCS). A meta-analysis comparing short (6 months) and long-term (12 months) DAPT has shown a lower risk of bleeding with no significant increase in ischemia risk associated with short DAPT use.

Monotherapy with a P2Y12 inhibitor clopidogrel has been proposed as a novel alternative to DAPT in patients with atherosclerotic cardiovascular disease. Clopidogrel has shown comparable bleeding events after PCI compared to aspirin, and reduced the risk of subsequent ischemic events. In addition, several trials have reported that clopidogrel monotherapy now has a lower risk of bleeding than antiplatelet drug therapy (DAPT). These results suggest that P2Y12 inhibitor monotherapy has a lower risk of bleeding in patients with PCI and can be compared with DAPT in preventing recurrent ischemic events.

Given that Genoss® Drug-Eluting Stent (DES) has a very low incidence of Stent Thrombosis (ST), short-term DAPT after PCI is now expected to reduce the risk of bleeding with clopidogrel instead of aspirin, without increasing cardiovascular events.
