Cangrelor
The recently published CHAMPION (Cangrelor
versus Standard Therapy to Achieve Optimal Management
of Platelet Inhibition) PHOENIX RCT
evaluated cangrelor, an intravenous direct-acting
ADP receptor antagonist with a short half-life.27
Among patients undergoing PCI who were not taking
ADP receptor antagonists, cangrelor re duced
major coronary events at 48 hours compared with
placebo (5.9% v. 4.7%; odds ratio 0.78, 95% CI
0.66–0.93) without increasing severe bleeding
events. A meta-analysis of the 3 CHAMPION trials
confirmed these findings, including a reduction in
stent thrombosis at 48 hours.
