Comparing ticagrelor and prasugrel for heart disease treatment

Switching From Dual Antiplatelet Therapy to Monotherapy With Potent P2Y12 Inhibitors: Pharmadodynamic Comparison Between Prasugrel and Ticagrelor Monotherapy. The Switching Antiplatelet -7 (SWAP-7) Study

Phase 4 Interventional University of Florida · NCT06691191

This study is testing whether ticagrelor or prasugrel is better at preventing bleeding and heart issues in patients with heart disease who have already been on another type of treatment.

What this trial studies

This study aims to compare the effectiveness of ticagrelor and prasugrel as single antiplatelet therapies after patients have undergone dual antiplatelet therapy for coronary artery disease. It will evaluate the pharmacodynamic profiles of both medications to determine if they are comparable in reducing bleeding events without increasing the risk of heart-related complications. The study will involve patients aged 18 to 75 who have been on dual antiplatelet therapy for at least 90 days following a percutaneous coronary intervention. Participants will be randomly assigned to receive either ticagrelor or prasugrel for the duration of the study.

Who should consider this trial

Good fit: Ideal candidates are adults aged 18 to 75 who have been on dual antiplatelet therapy for at least 90 days after a percutaneous coronary intervention.

Not a fit: Patients with a history of stent thrombosis, recent PCI, or those over 75 years old may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could help identify a safer and more effective antiplatelet therapy for patients with coronary artery disease.

How similar studies have performed: Previous studies have shown success with similar approaches, particularly with ticagrelor monotherapy demonstrating reduced bleeding events without increasing ischemic risk.
