The Effect of Reloading Prasugrel in a Patient Who Has Already Received a Loading Dose (LD) of Clopidogrel — SWITCH 600/60  

Acute Coronary Syndrome Clinical Trial

Official title:
SWITCH 600/60: The Effect of Reloading Prasugrel in a Patient Who Has Already Received a Loading Dose (LD) of Clopidogrel

Clinical Trial Summary

The primary objective of this study is to compare platelet reactivity between patients receiving a loading dose of clopidogrel and a reloading dose of prasugrel to patients receiving only a loading dose of prasugrel.

Clinical Trial Description

This is a prospective, open-label, non-randomized trial of approximately 260 patients with Acute Coronary Syndrome (ACS) undergoing percutaneous coronary intervention (PCI). In order to compare platelet reactivity, as assessed by the VerifyNow P2Y12 assay, we plan to recruit two study groups of interest:

1. Patients who have already received a 600 mg loading dose (LD) of clopidogrel in preparation for PCI will receive a loading dose of 60 mg of prasugrel.

2. Patients who have not received a LD of clopidogrel will receive a 60 mg LD of prasugrel prior to PCI.

A subset of 40 patients from each study group (80 patients total) will undergo additional platelet reactivity testing with the vasodilator stimulated phosphoprotein (VASP) assay.All patients will be followed throughout the duration of the hospital stay. ;
