Trial to Assess the Effects of Vorapaxar (SCH 530348; MK-5348) in Preventing Heart Attack and Stroke in Patients With Atherosclerosis (TRA 2°P - TIMI 50) (P04737)

The study is designed to determine whether vorapaxar, when added to the existing standard of care (SOC) for preventing heart attack and stroke (eg, aspirin, clopidogrel) in participants with a known history of atherosclerosis, will yield additional benefit over the existing standard of care without vorapaxar in preventing heart attack and stroke. The study is also designed to assess risk of bleeding with vorapaxar added to the standard of care versus the standard of care alone.
