About this study

This trial consists of two arms. One arm is a non pre-treatment arm. Participants in this arm will receive placebo immediately after NSTEMI diagnosis and prior to the diagnostic coronary angiography. A 60 mg prasugrel loading dose will be given immediately after coronary angiography when proceeding to PCI. Subsequently, participants will receive daily maintenance doses of prasugrel until day 30. Participants who are greater than or equal to 75 years of age or who have a body weight less than 60 kilograms (kg) will receive 5 mg oral dose daily. All others will receive a 10 mg oral daily maintenance dose for 30 days.

The other arm is a pre-treatment arm where participants will receive a split loading dose regimen with 30 mg of prasugrel administered immediately after NSTEMI diagnosis and prior to diagnostic coronary angiography. The remainder of the loading dose (30 mg) will be administered when the participants are proceeding to PCI. Subsequently, participants will receive daily maintenance doses of prasugrel until day 30. Participants who are greater than or equal to 75 years of age or who have a body weight less than 60 kg will receive 5 mg oral dose daily. All others will receive a 10 mg oral daily maintenance dose for 30 days.

Primary outcomes

  1. The Percentage of Participants With Occurrence of Cardiovascular (CV) Death, Myocardial Infarction (MI), Stroke, Urgent Revascularization (UR), or Glycoprotein (GP) IIb/IIIa Inhibitor Bailout

    Time frame: First loading dose (LD) through 7 days after first LD

    The percentage of participants is the total number of participants experiencing a CV death, MI, stroke, UR or GPIIb/IIIa Inhibitor bailout divided by number of participants in the treatment arm multiplied by 100. Endpoint events were adjudicated by the Clinical Endpoint Committee.

Secondary outcomes

  1. Percentage of Participants With All-Cause Death, Myocardial Infarction (MI), Stroke, or All Coronary Artery Bypass Graft (CABG) and Non-CABG Thrombolysis in Myocardial Infarction (TIMI) Major Bleeding

    Time frame: First loading dose (LD) through 7 days after first LD

    The percentage of participants is the total number of participants experiencing an all-cause death, MI, stroke or CABG and non-CABG TIMI major bleeding divided by number of participants in the treatment arm multiplied by 100. Endpoint events were adjudicated by the Clinical Endpoint Committee.

  2. Percentage of Participants With Incidence of Cardiovascular (CV) Death, Myocardial Infarction (MI), or Stroke Through 30 Days From First Loading Dose (LD)

    Time frame: First LD through 30 days after first LD

    The percentage of participants is the total number of participants experiencing a CV death, MI, or stroke divided by number of participants in the treatment arm multiplied by 100. Endpoint events were adjudicated by the Clinical Endpoint Committee.

  3. Percentage of Participants With Incidence of Cardiovascular (CV) Death or Myocardial Infarction (MI) Through 30 Days From First Loading Dose (LD)

    Time frame: First LD through 30 days after first LD

    The percentage of participants is the total number of participants experiencing a CV death or MI divided by number of participants in the treatment arm multiplied by 100. Endpoint events were adjudicated by the Clinical Endpoint Committee.

  4. Percentage of Participants With Incidence of Cardiovascular (CV) Death, Myocardial Infarction (MI), or Urgent Revascularization (UR) Through 30 Days From First Loading Dose (LD)

    Time frame: First LD through 30 days after first LD

    The percentage of participants is the total number of participants experiencing a CV death, MI, or UR divided by number of participants in the treatment arm multiplied by 100. Endpoint events were adjudicated by the Clinical Endpoint Committee.

  5. Percentage of Participants With Incidence of Cardiovascular (CV) Death Through 30 Days From First Loading Dose (LD)

    Time frame: First LD through 30 days after first LD

    The percentage of participants is the total number of participants experiencing a CV death divided by number of participants in the treatment arm multiplied by 100. Endpoint events were adjudicated by the Clinical Endpoint Committee.

  6. Percentage of Participants With Incidence of Definite or Probable Stent Thrombosis (ST) According to the Academic Research Consortium (ARC) Criteria Through 30 Days From First Loading Dose (LD)

    Time frame: First LD through 30 days after first LD

    ARC criteria were used to define ST. Definite ST is angiographic or pathologic confirmation of partial or total thrombotic occlusion within the peri-stent region, and at least one of the following additional criteria: acute ischemic symptoms; ischemic electrocardiogram changes; elevated cardiac biomarkers. Probable ST is any unexplained death within 30 days of stent implantation; any MI, which is related to documented acute ischemia in the territory of the implanted stent without angiographic confirmation of ST and in the absence of any other obvious cause. The percentage of participants is the total number of participants experiencing a definite or probable stent thrombosis divided by number of participants in the treatment arm multiplied by 100. Endpoint events were adjudicated by the Clinical Endpoint Committee.

  7. Percentage of Participants With All-cause Death, Myocardial Infarction (MI), Stroke, or All Coronary Artery Bypass Graft (CABG) and Non-CABG Thrombolysis in Myocardial Infarction (TIMI) Major Bleeding Through 30 Days From First Loading Dose (LD)

    Time frame: First LD through 30 days after first LD

    The percentage of participants is the total number of participants experiencing an all-cause death, MI, stroke or CABG and non-CABG TIMI major bleeding divided by number of participants in the treatment arm multiplied by 100. Endpoint events were adjudicated by the Clinical Endpoint Committee.

  8. Change in Standardized Troponin From Baseline to Percutaneous Coronary Intervention (PCI)

    Time frame: Baseline, before PCI (not greater than 48 hours after randomization)

    Standardized troponin is defined as the ratio of the assayed troponin value divided by the upper limit of normal (ULN). Least Squares (LS) means were obtained from an Analysis of Covariance (ANCOVA) model with treatment as a fixed effect and baseline standardized troponin as a covariate.

  9. Percentage of Participants With Incidence of All Coronary Artery Bypass Graft (CABG) or Non-CABG Thrombolysis In Myocardial Infarction (TIMI) Major Bleeding

    Time frame: First loading dose (LD) through 7 days after first LD

    The percentage of participants is the total number of participants experiencing a CABG or non-CABG TIMI major bleeding divided by number of participants in the treatment arm multiplied by 100. Endpoint events were adjudicated by the Clinical Endpoint Committee.

Other outcomes

  1. Summary of All-Cause Death

    Time frame: Randomization through 30 days

    All deaths, regardless of possible relatedness, were adjudicated by the Clinical Endpoint Committee (CEC) and are reported in this table.
