Overview
Brief Summary
A placebo-controlled, randomized, double-blind, parallel group, phase III multicenter study in subjects recently hospitalized for ACS and with the appropriate genetic profile. Subjects will provide informed consent before any study-specific procedures are performed. Subject enrollment may begin in the hospital and will continue following release from the hospital. Screening procedures may be performed at the time of the index ACS event or anytime thereafter, with the condition that randomization must occur within the mandated window (4-12 weeks after the index event). Subjects will be assessed based on their medical history. Those who are likely to qualify will undergo Genotype Assay testing to evaluate genetic determination for the presence of AA genotype.
Detailed Description
This is an event driven study to reach statistical power given all other assumptions. Subjects will visit the clinic 1 month after randomization and at regular intervals thereafter. Additionally, for any subject prematurely discontinuing study medication, assessments will be conducted every 6 months for the collection of study endpoints. Those who are likely to qualify will undergo Genotype Assay Testing to evaluate genetic determination or the presence of the AA genotype. The test is investigational and test procedures are Roche Molecular Diagnostics protocol ADCY9-COB-389.

Eligibility Criteria
Inclusion Criteria

Outcomes
Primary Outcomes
Composite of Cardiovascular Death, Resuscitated Cardiac Arrest, Non-Fatal Myocardial Infarction, and Non-Fatal Stroke
Time Frame: From randomization to the first occurrence of any component of the composite primary endpoint (median duration of follow-up was 39.9 months)
All efficacy endpoints were adjudicated by an independent clinical endpoint committee (CEC). The primary efficacy endpoint was the time from randomization to the first occurrence of any component of the composite endpoint, which included death from cardiovascular causes, resuscitated cardiac arrest, non-fatal myocardial infarction, or non-fatal stroke, as positively adjudicated by the CEC.
Secondary Outcomes
- Composite Endpoint of Cardiovascular Death, Resuscitated Cardiac Arrest, Non-Fatal Myocardial Infarction, Non-Fatal Stroke or Hospitalization for New or Worsening Heart Failure(From randomization to the first occurrence of any component of the composite secondary endpoint (median duration of follow-up was 39.9 months))
- Composite Endpoint of Cardiovascular Death, Resuscitated Cardiac Arrest, Non-Fatal Myocardial Infarction, Non-Fatal Stroke, Hospitalization for ACS (With Electrocardiogram Abnormalities) or Unanticipated Coronary Revascularization(From randomization to the first occurrence of any component of the composite secondary endpoint (median duration of follow-up was 39.9 months))
