History of Changes
  Purpose

The purpose of this study is to evaluate whether a higher dosage of clopidogrel with aspirin (two doses) will decrease the risk of ischemic complications (cardiac death (CV death), myocardial infarction (MI), stroke) after a percutaneous coronary intervention (PCI).

Primary Outcome Measures:
  • First Occurrence of CV Death / MI / Stroke - Clopidogrel Treatment Regimen Comparison [ Time Frame: 30 days ] [ Designated as safety issue: No ]

    The primary endpoint is the first occurrence of any of the following events:

    • Cardiovascular death (any death with a clear cardiovascular or unknown cause),
    • Myocardial Infarction (diagnosis of new Myocardial Infarction (MI) - nonfatal or fatal)
    • Stroke (presence of a new focal neurologic deficit thought to be vascular in origin, with signs or symptoms lasting more than 24 hours - nonfatal or fatal)

    reported between the randomization and Day 30 (inclusive), and validated by the blinded Event Adjudication Committee (EAC).


  • First Occurrence of CV Death / MI / Stroke - ASA Dose Comparison [ Time Frame: 30 days ] [ Designated as safety issue: No ]
  • First Occurrence of CV Death / MI / Stroke - Interaction Clopidogrel Treatment Regimen and ASA Dose Level [ Time Frame: 30 days ] [ Designated as safety issue: No ]
  • First Occurrence of CV Death / MI / Stroke - Clopidogrel Treatment Regimen Comparison in PCI Subgroup [ Time Frame: 30 days ] [ Designated as safety issue: No ]

Secondary Outcome Measures:
  • Occurrence of Major Bleeding - Clopidogrel Dose Regimen Comparison [ Time Frame: 30 days ] [ Designated as safety issue: Yes ]
    Major bleeding is defined as any severe bleeding (associated with any of the following: death, leading to a drop in hemoglobin ≥ 5 g/dl, significant hypotension with the need for inotropic agents, symptomatic intracranial hemorrhage, requirement for surgery or for a transfusion ≥ 4 units of red blood cells or equivalent whole blood) and other major bleeding (significantly disabling bleeding, or intraocular bleeding leading to significant loss of vision or bleeding requiring transfusion of 2-3 units of red blood cells or equivalent whole blood) after validation by the independent EAC.

  • Occurrence of Major Bleeding - ASA Dose Level Comparison [ Time Frame: 30 days ] [ Designated as safety issue: Yes ]
