A Safety and Efficacy Study to Confirm the Cardioprotective Effects of MC-1 in Patients Undergoing High-Risk CABG

Summary

The purpose of this study is to determine the effect of MC-1 on the combined incidence of cardiovascular death and nonfatal myocardial infarction (MI) up to and including 30 days following coronary artery bypass graft (CABG) surgery compared with placebo.

Outcome

Missed primary endpoint

paper The primary efficacy outcome occurred in 140 of 1510 patients (9.3%) in the MC-1 group and 133 of 1486 patients (9.0%) in the placebo group (risk ratio, 1.04; 95% confidence interval, 0.83-1.30; P = .76). PMID 18381567 ↗

paper In this population of intermediate- to high-risk patients undergoing CABG surgery, MC-1 did not reduce the composite of cardiovascular death or nonfatal MI. PMID 18381567 ↗
