Comparing Clopidogrel and Aspirin after Stent Implantation for Heart Disease

Clopidogrel Versus Aspirin MOnotherapy After 1- to 3-month of Dual-antiplatelet thErapy Following Zotarolimus-eluting Onyx Stents Implantation; C-MODE Trial

NA · Yonsei University · NCT05320926

This study is testing whether clopidogrel or aspirin is better for heart disease patients after they have received a stent to see which one helps them avoid complications in the year following their treatment.

What this trial studies

This clinical trial investigates the effectiveness of clopidogrel monotherapy versus aspirin monotherapy following a short-term dual antiplatelet therapy (DAPT) in patients with ischemic heart disease who have undergone percutaneous coronary intervention (PCI) with zotarolimus-eluting stents. Patients will be randomized to receive either clopidogrel or aspirin after a 1- to 3-month DAPT period, with stratification based on bleeding risk, clinical presentation, and lesion complexity. The primary outcome is the rate of net adverse clinical events (NACE) at 12 months post-PCI. This study aims to determine which antiplatelet agent is more beneficial for patients after short-term DAPT.

Who should consider this trial

Good fit: Ideal candidates are patients aged 19 to 84 who have received zotarolimus-eluting Onyx stents for ischemic heart disease.

Not a fit: Patients over 85 years old, those with acute myocardial infarction, or those with a life expectancy of less than one year may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could help identify the most effective antiplatelet therapy for patients after stent implantation, potentially improving patient outcomes.

How similar studies have performed: Previous studies have shown varying results with different antiplatelet therapies, indicating that this approach is relevant but may still yield novel insights.
