ADP-induced PRU represents the rate and extent of ADP-stimulated platelet aggregation and serves as a biomarker of clinical efficacy, with lower values indicating greater P2Y12 platelet inhibition. Observed PRU values are presented with statistical comparisons of difference in least squares mean (LS mean) PRU values between prasugrel and clopidogrel. Efficacy analyses are analyzed and presented separately for the LD and maintenance dose (MD) phase.

Efficacy analyses analyzed and presented separately for LD and maintenance dose (MD) phase. Analysis compares PRU for prasugrel LDs (30 mg and 60 mg) with clopidogrel 300-mg LD at 30 minutes post-LD. Data for Primary Cohort at 4 hours post-LD, already presented in first Primary Outcome Measure, are also presented here. ADP-induced PRU serves as biomarker of clinical efficacy, with lower values indicating greater P2Y12 platelet inhibition. Observed PRU values presented with statistical comparisons of least-squares mean (LS mean) difference between prasugrel and clopidogrel.
Adenosine Diphosphate (ADP)-Induced P2Y12 Reaction Units (PRU) Using the Accumetrics VerifyNow (VN) P2Y12 Assay at During Maintenance Dose (MD) Phase at 30 Days and 90 Days in Primary Cohort and Low Weight/Elderly Cohort
Efficacy analyses analyzed and presented separately for loading dose (LD) and MD phase. Analysis compares PRU for 3 prasugrel MDs (10 mg, 7.5 mg, and 5 mg) with clopidogrel 75-mg MD at 30 days post-MD. Data for Primary Cohort at 30 days post-LD, already presented in second Primary Outcome Measure, are also presented here. ADP-induced PRU serves as a biomarker of clinical efficacy, with lower values indicating greater P2Y12 platelet inhibition. Observed PRU values are presented with statistical comparisons of least squares (LS) mean difference between prasugrel and clopidogrel.
Percent Inhibition of Adenosine Diphosphate (ADP)-Induced P2Y12 Reaction Units (PRU) at 30 Minutes, 2 Hours, and 4 Hours Post-Loading Dose (LD) in Primary in Primary Cohort and Low Weight/Elderly Cohort
A higher percentage (percent inhibition least squares mean [LS mean]) represents greater platelet inhibition.
Percent Inhibition of Adenosine Diphosphate (ADP)-Induced P2Y12 Reaction Units (PRU) During the Maintenance Dose (MD) Phase at 30 Days and 90 Days in Primary Cohort and Low Weight/Elderly Cohort

Summary of Myocardial Infarction (MI), Stroke, Stent Thrombosis and Urgent Target Vessel Revascularization (UTVR) in Primary Cohort and Low Weight/Elderly Cohort
Nonfatal MI: American College of Cardiology (ACC) definition Nonfatal stroke: rapid onset of new, persistent neurologic deficit lasting >24 hours; classified as either ischemic or hemorrhagic based on imaging data, if available, or uncertain cause if imaging data was not available. Stent thrombosis: defined as definite, probable, or possible, based on Academic Research Consortium definitions. UTVR: percutaneous coronary intervention (PCI) or coronary artery bypass graft (CABG) for recurrent ischemia. Revascularization must have included the vessel(s) dilated at the initial procedure
Risk of Cardiovascular (CV) Death, Nonfatal Myocardial Infarction (MI), or Non-fatal Stroke
Risk was defined as the number of participants with events of CV death, nonfatal MI, or nonfatal stroke. CV death: death caused by CV event or not clearly attributable to non-CV causes. Nonfatal MI: per adapted American College of Cardiology definition. Nonfatal stroke: rapid onset of new, persistent neurologic deficit lasting more than 24 hours; either ischemic or hemorrhagic based on imaging data, if available, or uncertain cause if imaging data was not available. As a consequence of the overall low number of reported clinical events, composite endpoints were not analyzed.
Risk of Cardiovascular (CV) Death, Nonfatal Myocardial Infarction (MI), or Urgent Target Vessel Revascularization (UTVR)
Risk was defined as the number of participants with events of CV death, nonfatal MI, or UTVR. UTVR: percutaneous coronary intervention (PCI) or coronary artery bypass graft (CABG) for recurrent ischemia. Revascularization must have included the vessel(s) dilated at the initial procedure. As a consequence of the overall low number of reported clinical events, composite endpoints were not analyzed.
Risk of Cardiovascular (CV) Death, Nonfatal Myocardial Infarction (MI), Nonfatal Stroke, or Recurrent Myocardial Ischemia Requiring Hospitalization
Risk was defined as the number of events of CV death, nonfatal MI, nonfatal stroke or recurrent myocardial ischemia requiring hospitalization. Recurrent myocardial ischemia requiring hospitalization: rehospitalization for symptoms of myocardial ischemia at rest with either new ST-segment deviation ≥1 mm, or performance of a coronary revascularization procedure percutaneous coronary intervention (PCI) or coronary artery bypass graft (CABG) during the same hospital stay. As a consequence of the overall low number of reported clinical events, composite endpoints were not analyzed.
Risk of Cardiovascular (CV) Death, Nonfatal Myocardial Infarction (MI), Nonfatal Stroke, Urgent Target Vessel Revascularization (UTVR), or Recurrent Myocardial Ischemia Requiring Hospitalization (Analyzed Individually)
Risk was defined as the number of participants with events of CV death, nonfatal MI, nonfatal stroke, UTVR, or recurrent myocardial ischemia requiring hospitalization.
Risk of Definite or Probable Stent Thrombosis Per ARC (Academic Research Consortium) Definition
Risk was defined as the number of participants with events of definite or probable stent thrombosis. As a consequence of the overall low number of reported clinical events, composite endpoints were not analyzed.
Risk of Definite, Probable, or Possible Stent Thrombosis Per Academic Research Consortium (ARC) Definition
Risk was defined as the number of participants with events of definite, probable, or possible stent thrombosis. As a consequence of the overall low number of reported clinical events, composite endpoints were not analyzed.
Risk of All-cause Death in Primary Cohort and Low Weight/Elderly Cohort
Risk was defined as the number of participants with events of all-cause death.
Incidence of Non-coronary Artery Bypass Graft (CABG) Related Thrombolysis in Myocardial Infarction (TIMI) Life-threatening (a Subset of Non-CABG-related TIMI Major Bleeding), Major, Minor, and Minimal Bleeding
Bleeding events were classified and analyzed in accordance with the TIMI criteria definitions. Major bleeding: any intracranial hemorrhage (ICR) 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 but <5 gm/dL from baseline. Insignificant bleeding: any bleeding event that does not meet criteria for a Major or Minor bleed.
Incidence of CABG-related TIMI Major or Minor Bleeding.
Inpatient Healthcare Resource Utilization
Healthcare resource utilization data were modeled from historical analyses to determine initial hospitalization costs, total 30-day medical care costs, and total 90-day medical care costs.
Genetic Variation Related to Drug Metabolism and Transport Substudy Result Summary
The primary hypothesis for the genetics substudy was that CYP2C19 genetic variation has a significant effect on pharmacodynamic (PD) response to clopidogrel but not on PD response to prasugrel per change in PRU as measured by the Accumetrics VerifyNow P2Y12 device. Participants were classified by CYP2C19 genotype into predicted metabolic phenotypes according to literature-based functional predictions. These classifications were clustered into 2 groups: extensive metabolizer (EM) and reduced metabolizer (RM). A higher value for change in PRU indicates a greater level of platelet inhibition.
