Percent Change in Low Density Lipoprotein-Cholesterol (LDL-C) at Study Endpoint After Six Weeks of Treatment

Percent Change in LDL-C at study endpoint after six weeks of treatment is calculated as the difference between week 6 measure and baseline measure divided by baseline measure \*100.

Time frame: Baseline and 6 weeks

Population: Full Analysis Set (FAS): The FAS population includes all randomized participants who took at least 1 dose of study medication and had a baseline (BL) value and at least one post BL value.

The Percentage of Participants Achieving Designated Low Density Lipoprotein-Cholesterol (LDL-C) Levels After 6 Weeks of Treatment

The percentage of participants who achieved a target LDL-C goal of \< 100 mg/dL, of \<70 mg/dL, and of \<77 mg/dL at study endpoint after six weeks of treatment. The numerator is the number of participants in a treatment group who achieved a target LDL-C goal and the denominator is the total number of participants within that treatment group.
