NCT00500617

Brief Summary

The PREDICT study is to develop and validate a diagnostic blood ASGES (age, sex, gene expression score) or Corus CAD for atherosclerotic coronary artery disease (CAD). The Corus CAD (Age/Sex/Gene Expression score - ASGES) will use quantitative real-time PCR (RT-PCR) to quantify the expression of multiple genes from circulating peripheral blood cells to assess the presence of clinically significant CAD in a patient.

Outcome Measures

Primary Outcomes (1)

  • Algorithm AUC >0.50

    The primary analysis will be performed during the third segment of the study using a subset of the enrolled subjects ("primary subjects"). The primary endpoint for the PREDICT study is a validated algorithm that can accurately classify subjects with and without any coronary artery lesion with a ≥50% diameter stenosis, as measured by Core Laboratory blinded quantitative coronary angiography. In evaluating this endpoint, subjects will be classified as either cases or controls. The endpoint will be assessed by calculating the area under the curve (AUC) for the algorithm score, and testing against an AUC = 0.50 to determine clinical utility, using an alpha level of 0.05 (two-sided).
