Does an intensified oral loading strategy with prasugrel 60 mg improve outcomes compared to standard clopidogrel 600 mg loading in biomarker-negative patients undergoing elective PCI?
In biomarker-negative patients undergoing elective PCI, an intensified loading strategy with prasugrel did not show a conclusive difference in efficacy or safety compared to standard clopidogrel loading, though the trial was prematurely terminated.
BACKGROUND: Even among biomarker-negative patients undergoing elective percutaneous coronary intervention (PCI), periprocedural thrombotic and bleeding complications can lead to increased morbidity and mortality. Whether stronger platelet inhibition by an intensified oral loading strategy (ILS) before PCI impacts on outcomes among these patients in contemporary practice remains unclear. METHODS: This multicenter, randomized, assessor-blinded trial tested the hypothesis that in elective PCI prasugrel 60 mg (ILS) is superior to standard loading strategy with clopidogrel 600 mg regarding a composite primary end point of all-cause death, any myocardial infarction, definite/probable stent thrombosis, stroke, or urgent vessel revascularization. After PCI, all patients were on clopidogrel 75 mg/day and aspirin. The trial was terminated prematurely because of slower-than-expected recruitment and funding discontinuation. RESULTS: =0.70, respectively. CONCLUSIONS: In biomarker-negative stable and unstable angina patients undergoing elective PCI, the trial did not find a conclusive difference in efficacy or safety. This observation should be interpreted in the context of wide CIs and premature termination of the trial. Registration: URL: https://www.clinicaltrials.gov. Unique identifier: NCT02548611.
