Cangrelor is a P2Y₁₂ inhibitor under investigation as an antiplatelet drug^[1] for intravenous application. Some P2Y₁₂ inhibitors are used clinically as effective inhibitors of adenosine diphosphate-mediated platelet activation and aggregation.^[1] Unlike clopidogrel (Plavix), which is a prodrug, cangrelor is an active drug not requiring metabolic conversion.

Poor interim results led to the abandonment of the two CHAMPION clinical trials in mid-2009.^[2] The BRIDGE study, for short term use prior to surgery, continues.^[3] The CHAMPION PHOENIX trial was a randomized study of over 11,000 patients published in 2013. It found usefulness of cangrelor in patients getting cardiac stents. Compared with clopidogrel given around the time of stenting, intravenous ADP-receptor blockade with cangrelor significantly reduced the rate of stent thrombosis and myocardial infarction.^[4] Reviewers have questioned the methodology of the trial.^[5]
