Adenosine Diphosphate (ADP)-Induced P2Y12 Receptor-mediated Platelet Aggregation (P2Y12 Reaction Units; PRU) Using the Accumetrics VerifyNow (VN) P2Y12 Assay at 4 Hours Post-Loading Dose (LD) in Primary Cohort (≥60 kg and <75 Years)
Časové okno: At 4 hours following LD administration
|
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. |

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
Časové okno: 30 days and 90 days
|
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. |

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. |

Genetic Variation Related to Drug Metabolism and Transport Substudy Result Summary
Časové okno: Baseline to 4 hours post-loading dose (LD), 30 days and 90 days during maintenance dose (MD) phase
|
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. |
