Brief summary
The primary objective of this study is to demonstrate that the efficacy of cangrelor (combined with usual care) is superior to that of usual care, in subjects requiring percutaneous coronary intervention (PCI) as measured by a composite of all-cause mortality, myocardial infarction (MI), and ischemia-driven revascularization (IDR).
Interventions
cangrelor bolus (30 mcg/kg) & cangrelor infusion (4 mcg/kg/min) administered from randomization for at least 2 hours, or until the end of the PCI, whichever is longer with the option to extend up to 4 hours maximum (per investigator discretion)
clopidogrel capsules (600 mg) at end of PCI
placebo bolus (30 mcg/kg) & placebo infusion (4 mcg/kg/min) administered from randomization for at least 2 hours, or until the end of the PCI, whichever is longer with the option to extend up to 4 hours maximum (per investigator discretion)
Placebo capsules given at the end of PCI to mimic 600mg clopidogrel dosing
Placebo capsules given at the end of infusion to mimic 600mg clopidogrel dosing

Eligibility
Inclusion criteria
Angiography demonstrating atherosclerosis amenable to treatment by percutaneous coronary intervention (PCI) with or without stent implantation and diagnosis of Acute Coronary Syndrome (ACS) by elevated cardiac markers or ischemic chest discomfort w/electrocardiogram changes + age \> 65 or diabetes.
Exclusion criteria
1. Not a candidate for PCI 2. ST-segment elevation myocardial infarction (STEMI) within 48 hours of randomization 3. Increased bleeding risk: ischemic stroke within the last year or any previous hemorrhagic stroke, intra-cranial tumor, cerebral arteriovenous malformation, or intracranial aneurysm; recent (\<1 month) trauma or major surgery \[including coronary artery bypass graft (CABG) surgery\]; currently receiving warfarin, active bleeding 4. Impaired hemostasis: known International Normalized Ratio (INR) \>1.5 at screening; past or present bleeding disorder (including congenital bleeding disorders such as von Willebrand's disease or hemophilia, acquired bleeding disorders, and unexplained clinically significant bleeding disorders), thrombocytopenia (platelet count \<100,000/µL) at screening 5. Severe hypertension not adequately controlled by antihypertensive therapy at the time of randomization 6. Receipt of fibrinolytic therapy in the 12 hours preceding randomization 7. Receipt of any thienopyridine (clopidogrel or ticlopidine) in the 7 days preceding randomization 8.

Recruitment details
Patients were selected for randomization based on the need for percutaneous coronary intervention (PCI). Randomization could only occur after the need for PCI was confirm by angiography.
