Cangrelor to Clopidogrel or Prasugrel Transition Study

Completed · Phase 2

Conditions studied: Coronary Artery Disease (CAD)

In brief

There are two separate objectives in this study: 1. To demonstrate the pharmacodynamic (PD) profile when participants treated with cangrelor are switched to oral prasugrel 60 mg administered 30 minutes (min) after cangrelor infusion is discontinued 2. To demonstrate the PD profile when participants treated with cangrelor are switched to oral clopidogrel 600 mg administered during or immediately after cangrelor infusion.
