Individualized treatment for patients with coronary artery disease

Pharmacodynamic Outcomes in Patients With Coronary Artery Disease Undergoing Percutaneous Coronary Intervention Treated With an Individualized Treatment STRATEGY

Phase 4 Interventional St. Antonius Hospital · NCT05773989

This study is testing if using a personalized blood-thinning treatment based on patients' genes can help people with coronary artery disease have better outcomes and fewer side effects after heart procedures.

What this trial studies

This study evaluates the pharmacodynamic response of patients with Chronic Coronary Syndrome (CCS) undergoing elective percutaneous coronary intervention (PCI) when treated with genotype-guided P2Y12-inhibitor monotherapy compared to standard dual antiplatelet therapy (DAPT). Patients will be randomized to receive either clopidogrel monotherapy or a P2Y12-inhibitor based on their CYP2C19 genotype. The study aims to assess bleeding and ischemic outcomes over a 6-month period. By personalizing treatment based on genetic factors, the study seeks to optimize patient outcomes while minimizing risks associated with antithrombotic therapy.

Who should consider this trial

Good fit: Ideal candidates are adults aged 18 and older with Chronic Coronary Syndrome undergoing elective PCI.

Not a fit: Patients with contraindications to the study medications 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 approach could lead to more effective and safer antithrombotic therapy for patients with coronary artery disease.

How similar studies have performed: Other studies have shown promise with genotype-guided antithrombotic strategies, indicating potential for success in this approach.
