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

Eli Lilly and Company13,619 enrolled

Overview

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.

Inclusion Criteria: * A person who has been diagnosed with acute coronary syndrome and is to undergo a percutaneous coronary intervention. * A person who is of the legal age of 18 and is mentally competent to provide a signed written informed consent. * If a woman is of childbearing potential (i.e., before menopause), she must test negative for pregnancy and agree to use a reliable method of birth control. Exclusion Criteria: * 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. * Individuals who are at an increased risk of bleeding based on laboratory criteria evaluated by the treatment physician or on medication that can cause bleeding. * A person who has liver disease; for example, cirrhosis. * A person who has a condition such as alcoholism, mental illness, or is drug dependent. * A person who has cardiogenic shock, a refractory ventricular arrhythmia, or congestive heart failure (class IV).

Outcomes

Primary Outcomes

Number of Subjects Reaching the Composite Endpoint of Cardiovascular (CV) Death, Nonfatal Myocardial Infarction (MI), or Nonfatal Stroke

The endpoint in this measure is a combination of CV death, nonfatal MI, or nonfatal stroke. The data is presented by the study population, which is represented as follows: 1) subjects who presented with unstable angina and non-ST-segment elevation myocardial infarction (UA/NSTEMI), 2) subjects who presented with ST segment elevation myocardial infarction (STEMI), and 3) all subjects with acute coronary syndromes (ACS) (i.e. all subjects with UA/NSTEMI or STEMI).

Time frame: Randomization up to 15 months

Secondary Outcomes

Number of Treated Subjects With Non-Coronary Artery Bypass Graft (CABG) Related Thrombolysis In Myocardial Infarction (TIMI) Study Group Major and Minor Bleeding Events

TIMI classification for major and minor bleeding in the subset of subjects who did not undergo a coronary artery bypass operation (CABG) were defined as follows: Major bleeding: any intracranial hemorrhage (ICH) OR any clinically overt bleeding (including bleeding evident on imaging studies) associated with a fall in hemoglobin (Hgb) of ≥5 grams/deciliter (gm/dL)from baseline. Minor Bleeding: any clinically overt bleeding associated with a fall in Hgb of ≥3 gm/dL but \<5 gm/dL from baseline. Major bleeding events were further examined as events that were deemed life threatening and/or fatal.

Time frame: First dose of study drug up to 15 months (while at risk)

Number of Subjects Reaching the Composite Endpoint of Cardiovascular (CV) Death, Nonfatal Myocardial Infarction (MI), or Urgent Target Vessel Revascularization (UTVR)

The endpoint in this measure is a combination of CV death, nonfatal MI, or UTVR. Results are reported for the All ACS subject population for the 30 and 90 day periods.

Time frame: Randomization to 30 days; randomization to 90 days

Number of Subjects Reaching the Composite Endpoint of Cardiovascular (CV) Death, Nonfatal Myocardial Infarction (MI), or Nonfatal Stroke

The endpoint in this measure is a combination of CV death, nonfatal MI, or nonfatal stroke. Results are reported for the All ACS population for the 30 and 90 day periods.

Time frame: Randomization to 30 days; randomization to 90 days

Number of Subjects Reaching the Composite Endpoint of Cardiovascular (CV) Death, Nonfatal Myocardial Infarction (MI), Nonfatal Stroke, or Rehospitalization for Cardiac Ischemic Events

The endpoint in this measure is a combination of CV death, nonfatal MI, nonfatal stroke, or rehospitalization for cardiac ischemic events. Results are reported for the All ACS population.

Time frame: Randomization up to 15 months

Number of Subjects Reaching the Composite Endpoint of All-Cause Death, Nonfatal Myocardial Infarction (MI), or Nonfatal Stroke

The endpoint in this measure is a combination of all-cause death, nonfatal MI, or nonfatal stroke. Results are reported for the All ACS population.

Time frame: Randomization up to 15 months
