Study Details

Brief summary:

  • The purpose of this study is to determine the level of inhibition of platelet activation of an approved thienopyridine(clopidogrel or prasugrel) and aspirin regimen in the setting of drug eluting coronary stent implantation.
  • In subjects with high residual levels of platelet reactivity after receiving either a maintenance or loading dose of either clopidogrel or prasugrel, a cross over of thienopyridine treatment to the alternate medication will occur.
  • The study tests the hypothesis that adequate platelet inhibition will occur in subjects who have high levels of platelet reactivity and are subsequently switched from clopidogrel to prasugrel(loading or maintenance dose) without increased episodes of bleeding or MACE events at discharge and 30 days post Percutaneous Coronary Intervention (PCI).

Interventions and Outcome Measures

Arms

active comparator: Maintenance Dose Arm

Open label clopidogrel 75 mg daily or prasugrel 10 mg daily

active comparator: Loading Dose Arm

Clopidogrel 600 mg or Prasugrel 60 mg at time of PCI.

Interventions

Loading Dose Arm

Subjects who are thienopyridine naive will be randomized 1:1 to either clopidogrel 600 mg or prasugrel 60 mg loading dose at the time of PCI. A Verify Now P2Y12 platelet assay will measure platelet reactivity. Cross over to loading dose and maintenance dose of alternate medication will occur based on level of platelet reactivity.

Maintenance Dose Arm

Verify Now P2Y12 platelet assay will measure platelet reactivity. Cross over to a loading dose and maintenance dose of alternate medication will occur based on level of platelet reactivity.

Primary outcome measure

  • Change in platelet reactivity after switching medication regimen of two thienopyridines- clopidogrel and prasugrel [ Time Frame: 4 hours post medicaton administration ]
