Number of Participants With First Occurrence of Any Component of the Composite of Major Adverse Cardiovascular Events (Cardiovascular [CV] Death, Non-fatal Myocardial Infarction [MI] or Non-fatal Stroke) During the Time Period for Follow-up of CV Events [ Time Frame: From randomization until the End-of-Treatment visit or the last date on which endpoints were able to be assessed (up to 4.25 years/average of 3.51 years) ]
CV death=death due to a CV cause, which included but was not limited to deaths resulting from stroke, arrhythmia, sudden death (witnessed/unwitnessed), MI, heart failure, pulmonary embolism, peripheral arterial disease, or complications of a CV procedure. Deaths not clearly attributable to non-CV causes are considered to be CV deaths. Acute MI=evidence of myocardial necrosis in a clinical setting consistent with myocardial ischemia. Prior MI diagnosed post-randomization (e.g., silent MI)=the development of new pathological Q waves with/without symptoms OR imaging evidence of a region of loss of viable myocardium that is thinned and fails to contract, in the absence of a non-ischemic cause (pre-event imaging data required for verification of new abnormality), OR pathological findings of a healed/healing MI. Stroke=presence of a new focal neurologic deficit thought to be of vascular origin, with signs/symptoms lasting >24 hours or results in death (in <24 hours).
Time to the first occurrence of any component of the composite of Major Adverse Cardiovascular Events [MACE: CV death (death due to a cardiovasacular cause), non-fatal myocardial infarction, non-fatal stroke] [ Time Frame: Patients will remain in the study until a specified number of MACE events have occurred. It is anticipated that patients will be in the study about 3 years. ]

  • Number of Participants With First Occurrence of Any Event in the Composite of Major Coronary Events (Coronary Heart Disease [CHD] Death, Non-fatal MI, or Urgent Coronary Revascularization [CR] for MI) During the Time Period for Follow-up (FU) of CV Events [ Time Frame: From randomization until the End-of-Treatment visit or the last date on which endpoints were able to be assessed (up to 4.25 years/average of 3.51 years) ]
    CHD death=occurrence of a fatal MI, death caused by documented cardiac arrest, death resulting from heart failure in a participant with known CHD, death from other forms of acute/chronic CHD, unwitnessed death of unknown origin, or sudden death. Acute MI=evidence of myocardial necrosis in a clinical setting consistent with myocardial ischemia. Prior MI diagnosed post-randomization (e.g.,silent MI)=the development of new pathological Q waves with/without symptoms OR imaging evidence of a region of loss of viable myocardium that is thinned and fails to contract, in the absence of a non-ischemic cause (pre-event imaging data required for verification of new abnormality), OR pathological findings of a healed/healing MI. Urgent CR for MI=ischemic discomfort at rest that prompted CR (percutaneous coronary intervention [PCI: any attempt at CR even if not successful] or coronary artery bypass graft) during the same hospitalization or resulted in hospital transfer for the purpose of CR.
  • Number of Participants With First Occurrence of Any Event in the Composite of Total Coronary Events (CHD Death, Non-fatal MI, Hospitalization for Unstable Angina, or Any Coronary Revascularization Procedure) During Time Period for FU of CV Events [ Time Frame: From randomization until the End-of-Treatment visit or the last date on which endpoints were able to be assessed (up to 4.25 years/average of 3.51 years) ]
    CHD death, acute MI, and prior MI are defined in the previous secondary endpoint (major coronary events). Hospitalization for unstable angina=one of the following, but not fulfilling the criteria for MI: ischemic discomfort at rest associated with electrocardiogram (ECG) changes leading to hospitalization; ischemic discomfort at rest regardless of ECG changes leading to hospitalization and revascularization during the same admission; ischemic discomfort at rest in hospital associated with ECG changes; ischemic discomfort at rest in hospital without ECG changes resulting in revascularization during the same admission. NOTE: The event was not considered to be unstable angina if, after invasive/non-invasive testing or other diagnostic testing, the discomfort is found not to be caused by myocardial ischemia.
  • Number of Participants With CV Death During the Time Period for Follow-up of CV Events [ Time Frame: From randomization until the End-of-Treatment visit or the last date on which endpoints were able to be assessed (up to 4.25 years/average of 3.51 years) ]
    CV death is defined as a death due to a CV cause, which included but was not limited to deaths resulting from stroke, arrhythmia, sudden death (witnessed/unwitnessed), MI, heart failure, pulmonary embolism, peripheral arterial disease, or complications of a CV procedure. Deaths not clearly attributable to non-CV causes are considered to be CV deaths.
  • Number of Participants With First Occurrence of MI (Fatal/Non-fatal) During the Time Period for Follow-up of CV Events [ Time Frame: From randomization until the End-of-Treatment visit or the last date on which endpoints were able to be assessed (up to 4.25 years/average of 3.51 years) ]
    Acute MI is defined as evidence of myocardial necrosis in a clinical setting consistent with myocardial ischemia. Prior MI diagnosed post-randomization (e.g., silent MI)=the development of new pathological Q waves with/without symptoms OR imaging evidence of a region of loss of viable myocardium that is thinned and fails to contract, in the absence of a non-ischemic cause (pre-event imaging data required for verification of new abnormality), OR pathological findings of a healed/healing MI.
  • Number of Participants With First Occurrence of Stroke (Fatal/Non-fatal) During the Time Period for Follow-up of CV Events [ Time Frame: From randomization until the End-of-Treatment visit or the last date on which endpoints were able to be assessed (up to 4.25 years/average of 3.51 years) ]
    Stroke is defined as the presence of a new focal neurologic deficit thought to be of vascular origin, with signs/symptoms lasting >24 hours or results in death (in <24 hours).
  • Number of Participants With First Occurrence of Any Component of the Composite of All-cause Mortality, Non-fatal MI, or Non-fatal Stroke During the Time Period for Follow-up of CV Events [ Time Frame: From randomization until the End-of-Treatment visit or the last date on which endpoints were able to be assessed (up to 4.25 years/average of 3.51 years) ]
    Acute MI is defined as evidence of myocardial necrosis in a clinical setting consistent with myocardial ischemia. Prior MI diagnosed post-randomization (e.g., silent MI)=the development of new pathological Q waves with/without symptoms OR imaging evidence of a region of loss of viable myocardium that is thinned and fails to contract, in the absence of a non-ischemic cause (pre-event imaging data required for verification of new abnormality), OR pathological findings of a healed/healing MI.

The Stabilization of Atherosclerotic Plaque by Initiation of Darapladib Therapy Trial
LPL100601, A Clinical Outcomes Study of Darapladib Versus Placebo in Subjects With Chronic Coronary Heart Disease to Compare the Incidence of Major Adverse Cardiovascular Events (MACE)
This study will test whether darapladib can safely lower the chances of having a cardiovascular event (such as a heart attack or stroke) in people with coronary heart disease.
Subjects who qualify for the study will be randomized 1:1 to either darapladib or placebo administered in addition to standard therapy. Following the baseline visit, subjects will be expected to return for clinic visits at 1 month, 3 months, and every 6 months until the end of the study. Average time in the study for an individual subject is expected to be about 3 years.
