Phase III

First Patient In 08-Nov-2007; Last Patient Last Visit 23-Mar-2009

Pre-Assignment Details
Significant events and approaches for the overall study following participant enrollment, but prior to group assignment
The study evaluated patients ≥ 65 years of age at moderately high or high risk for Coronary Heart Disease (CHD), with or without atherosclerotic vascular disease. The study was a 3-week single-blind placebo run-in period and a 12-week active treatment period where patients were equally randomized to one of 5 treatment groups for 12 weeks
