A Clinical trial comparing Cangrelor
to Clopidogrel in subjects who require percutaneous coronary intervention (PCI) to demonstrate that cangrelor is superior, or at least non-inferior, to that of clopidogrel as measured by a composite of all-cause mortality, myocardial infarction (MI) and ischaemia driven revascularisation (IDR).

Study type
Description of intervention(s) / exposure
Subjects who fulfill the criteria and are to under go PCI will be randomised on a 1:1 randomisation to receive either 4 placebo capsules orally plus Cangrelor bolus (30ug/kg) & infusion (4 ug/kg/min) for at least 2 hours or the duration of the procedure, whichever is longer. Post infusion be administered 4 Clopidogrel capsules (600mg) orally once. The other group would receive 4 Clopidogrel capsules (600mg) plus Placebo bolus (30 ug/kg) and infusion (4 ug/kg/min) for the duration of the procedure or 2 hours whichever is longer. At the end of the infusion they will receive 4 placebo capsules once. Clopidogrel maintenance is at the physicians discretion.

Brief summary
Each year over 1 million patients globally undergo diagnostic angiography and are discovered to have atherosclerotic plaque amenable to percutaneous coronary intervention (PCI). This area has been extensively researched and benefit shown with the use of aspirin, and more recently 300mg loading dose and 75mg maintenance dose of clopidogrel. Despite the apparent benefit, many patients still do not receive a loading dose (either deliberately – as there is a reasonable probability of being triaged to CABG) or because there is insufficient time (stable patients undergoing diagnostic angiogram who proceed immediately to PCI). Cangrelor is a new drug being developed, which in early phase trials appears to be safe and well tolerated & will provide platelet inhibition throughout the infusion with full recovery of platelet function within 60min of stopping the infusion. This trial aims to demonstrate the efficacy of cangrelor compared to clopidogrel in patients requiring PCI. The primary endpoints to be measured will be all cause mortality, myocardial infarction (MI) and ischemia driven reinfarction (IDR) at 48hrs and 1 month, then mortality at 1year. This study will employ double blind and double dummy tachniques in addition to an active control. Subjects, Investigators, Study Monitor, Data Analyst and the sponsor The Medicines Company will be blinded.
