The Thrombin Receptor Antagonist for Clinical Event Reduction in Acute Coronary Syndrome (TRA*CER) trial: study
Background:
The protease-activated receptor 1 (PAR-1), the main platelet receptor for thrombin, represents a novel target for treatment of arterial thrombosis, and SCH 530348 is an orally active, selective, competitive PAR-1 antagonist. We designed TRA*CER to evaluate the efficacy and safety of SCH 530348 compared with placebo in addition to standard of care in patients with non-ST-segment elevation (NSTE) acute coronary syndromes (ACS) and high-risk features.
Trial Design:
TRA*CER is a prospective, randomized, double-blind, multicenter, phase III trial with an original estimated sample size of 10,000 subjects. Our primary objective is to demonstrate that SCH 530348 in addition to standard of care will reduce the incidence of the composite of cardiovascular death, myocardial infarction (MI), stroke, recurrent ischemia with rehospitalization, and urgent coronary revascularization compared with standard of care alone. Our key secondary objective is to determine whether SCH 530348 will reduce the composite of cardiovascular death, MI, or stroke compared with standard of care alone. Secondary objectives related to safety are the composite of moderate and severe GUSTO bleeding and clinically significant TIMI bleeding. The trial will continue until a predetermined minimum number of centrally adjudicated primary and key secondary end point events have occurred and all subjects have participated in the study for at least 1 year. The TRA*CER trial is part of the large phase III SCH 530348 development program that includes a concomitant evaluation in secondary prevention.
Conclusion:
TRA*CER will define efficacy and safety of the novel platelet PAR-1 inhibitor SCH 530348 in the treatment of high-risk patients with NSTE ACS in the setting of current treatment strategies.
Insights
The TRA*CER trial investigates SCH 530348, a novel protease-activated receptor-1 (PAR-1) antagonist, for treating high-risk patients with non-ST-segment elevation acute coronary syndromes (NSTE ACS). This study aims to define its efficacy and safety in reducing cardiovascular events.
Area of Science:
- Cardiovascular Medicine
- Pharmacology
- Clinical Trials
Background:
- Protease-activated receptor 1 (PAR-1) is a key platelet receptor for thrombin and a novel target for arterial thrombosis treatment.
- SCH 530348 is an orally active, selective, competitive PAR-1 antagonist.
- Non-ST-segment elevation acute coronary syndromes (NSTE ACS) with high-risk features require effective therapeutic strategies.
Purpose of the Study:
- To evaluate the efficacy and safety of SCH 530348 compared with placebo in patients with NSTE ACS and high-risk features.
- To demonstrate SCH 530348's ability to reduce the incidence of major adverse cardiovascular events when added to standard care.
- To assess the safety profile of SCH 530348, including bleeding events.
Main Methods:
- TRA*CER is a prospective, randomized, double-blind, multicenter, phase III trial.
- The study includes approximately 10,000 subjects.
- Primary endpoint: composite of cardiovascular death, myocardial infarction (MI), stroke, recurrent ischemia with rehospitalization, and urgent coronary revascularization. Key secondary endpoint: composite of cardiovascular death, MI, or stroke. Safety endpoints include bleeding events.
Main Results:
- Results are pending completion of the trial, which requires a predetermined number of adjudicated primary and key secondary endpoint events.
- The trial is designed to provide definitive data on the efficacy and safety of SCH 530348 in the target population.
- The study will continue until all subjects have at least 1 year of follow-up.
Conclusions:
- The TRA*CER trial is expected to define the efficacy and safety of the novel PAR-1 inhibitor SCH 530348.
- Findings will inform treatment strategies for high-risk NSTE ACS patients.
- This study is part of a larger phase III development program for SCH 530348.
