A Comparison of CS-747 and Clopidogrel in Acute Coronary Syndrome Subjects Who Are to Undergo Percutaneous Coronary Intervention

The sponsors of this investigational drug are developing prasugrel (also known as CS-747) as a possible treatment for patients with acute coronary syndrome (heart attack or chest pain) who need, or are expected to need, a percutaneous coronary intervention (PCI; also called a balloon angioplasty). Prasugrel was compared with Clopidogrel to determine which drug is better at reducing deaths, future heart attacks, or stroke.

• A person who has had an ischemic stroke within the last 3 months or a hemorrhagic stroke at any time in the past.
• A person who has active internal bleeding or has a history of a bleeding disorder.
