Abstract

Dual antiplatelet therapy consisting of aspirin and a P2Y 12-receptor antagonist is important for preventing major adverse cardiovascular events in patients managed with percutaneous coronary intervention (PCI). The current P2Y12-receptor antagonists are only available for oral administration and exhibit a delayed onset of action. Furthermore, several days are required for platelet function to return to normal following cessation of therapy. Cangrelor is an intravenous ATP analog that directly, selectively and reversibly inhibits P2Y12 receptors on platelets. A 30-μg/kg bolus dose followed by a 4-μg/kg per minute continuous infusion of cangrelor achieves peak concentration and maximal platelet inhibition within minutes of administration. Cangrelor also demonstrates a fast offset as normal platelet function is restored 1-2 h after cessation of the infusion. Three large, double-blind, randomized trials - CHAMPION PLATFORM, CHAMPION PCI and CHAMPION PHOENIX - assessed the efficacy and safety of cangrelor compared with clopidogrel (during or immediately after PCI) or placebo in the setting of PCI. In the most recent CHAMPION PHOENIX trial, cangrelor was superior to clopidogrel for preventing adverse cardiovascular events with no significant increase in major bleeding. Based on the clinical trial results combined with unique properties such as intravenous administration and fast onset and offset, cangrelor may provide benefit in certain patients undergoing PCI.
