Primary Outcome Measures:
  • Percent Change From Baseline to Week 6 in Low-Density Lipoprotein (LDL)-C [ Time Frame: Baseline and 6 weeks ]
    Percent Change in LDL-C = [(week 6 value - baseline value)/baseline value]*100%


Secondary Outcome Measures:
  • Percent Change From Baseline to Week 6 in High-Density Lipoprotein Cholesterol (HDL-C) [ Time Frame: Baseline and 6 weeks ]
    Percent Change in HDL-C = [(week 6 value - baseline value)/baseline value]*100%

  • Percent Change From Baseline to Week 6 in Non-High-Density Lipoprotein Cholesterol (Non-HDL-C) [ Time Frame: Baseline and 6 Weeks ]
    Percent Change in Non-HDL-C = [(week 6 value - baseline value)/baseline value]*100%

  • Percent Change From Baseline to Week 6 in Total-Cholesterol [ Time Frame: Baseline and 6 Weeks ]
    Percent Change in Total-C = [(week 6 value - baseline value)/baseline value]*100%

  • Percent Change From Baseline to Week 6 in Triglycerides (TG) [ Time Frame: Baseline and 6 Weeks ]
    Percent Change in TG = [(week 6 value - baseline value)/baseline value]*100%

  • Percent Change From Baseline to Week 6 in Apolipoprotein B (Apo B) [ Time Frame: Baseline and 6 Weeks ]
    Percent Change in Apo B = [(week 6 value - baseline value)/baseline value]*100%

  • Percent Change From Baseline to Week 6 in Apolipoprotein A-I (Apo A-I) [ Time Frame: Baseline and 6 Weeks ]
    Percent Change in Apo A-I = [(week 6 value - baseline value)/baseline value]*100%

  • Percent Change From Baseline to Week 6 in Total-Cholesterol (TC):High-Density Lipoprotein Cholesterol (HDL-C) Ratio [ Time Frame: Baseline and 6 Weeks ]
    Percent Change in TC:HDL-C Ratio = [(week 6 ratio - baseline ratio)/baseline ratio]*100%

  • Percent Change From Baseline to Week 6 in Low-Density Lipoprotein-Cholesterol:High-Density Lipoprotein-Cholesterol (LDL-C:HDL-C) Ratio [ Time Frame: Baseline and 6 Weeks ]
    Percent Change in LDL-C:HDL-C Ratio = [(week 6 ratio - baseline ratio)/baseline ratio]*100%

  • Percent Change From Baseline to Week 6 in Apolipoprotein B:Apolipoprotein A-I (Apo B:Apo A-I) Ratio [ Time Frame: Baseline and 6 Weeks ]
    Percent Change in Apo B:Apo A-I Ratio = [(week 6 ratio - baseline ratio)/baseline ratio]*100%

  • Percent Change From Baseline to Week 6 in Non-High-Density Lipoprotein-Cholesterol:High-Density Lipoprotein-Cholesterol (Non-HDL-C:HDL-C) Ratio [ Time Frame: Baseline and 6 Weeks ]
    Percent Change in non-HDL-C:HDL-C Ratio = [(week 6 ratio - baseline ratio)/baseline ratio]*100%

  • Percent Change From Baseline to Week 6 in C Reactive Protein (CRP) [ Time Frame: Baseline and 6 Weeks ]
    Percent Change in CRP = [(week 6 value - baseline value)/baseline value]*100%

  • Number of Patients Who Attained Target Low-Density Lipoprotein Cholesterol (LDL-C) <70 mg/dL at Week 6 [ Time Frame: 6 Weeks ]
