Baseline IVUS interrogation determined to be unacceptable by the Imaging Core Lab 3. Subjects with uncontrolled diabetes defined as HbA1c > 10% at Screening 4. Subjects with triglycerides >500 mg/dL at Screening 5. Subjects with coronary artery bypass graft (CABG) surgery in previous 6 weeks or in whom CABG is planned 6.

E.5 End points |
E.5.1 | Primary end point(s) |
Primary endpoint: comparison of the primary efficacy parameter between randomized treatment groups (Placebo vs. CER-001 3 mg/kg) using an analysis of covariance (ANCOVA) with adjustment for baseline PAV. Adjusted mean endpoint in each treatment group and the difference in means (95% confidence interval) will be presented. Statistical significance will be assessed at the alpha=0.05 level. |
