Primary Outcome Measures:
  • Part A: Percent Change From Baseline in Low Density Lipoprotein Cholesterol (LDL-C) at Week 12 [ Time Frame: Baseline and Week 12 ]
    LDL-C was quantified using the ultracentrifugation method.

  • Part B: Percent Change From Baseline in Low Density Lipoprotein Cholesterol (LDL-C) at Week 12 [ Time Frame: Baseline and Week 12 ]
    LDL-C was quantified using the ultracentrifugation method.


Secondary Outcome Measures:
  • Part A: Change From Baseline in LDL-C at Week 12 [ Time Frame: Baseline and Week 12 ]
    LDL-C was quantified using the ultracentrifugation method.

  • Part A: Percent Change From Baseline in Non-High Density Lipoprotein Cholesterol (Non-HDL-C) at Week 12 [ Time Frame: Baseline and Week 12 ]
  • Part A: Percent Change From Baseline in Apolipoprotein B at Week 12 [ Time Frame: Baseline and Week 12 ]
  • Part A: Percent Change From Baseline in the Total Cholesterol/HDL-C Ratio at Week 12 [ Time Frame: Baseline and Week 12 ]
  • Part A: Percent Change From Baseline in Apolipoprotein B/Apolipoprotein A1 Ratio at Week 12 [ Time Frame: Baseline and Week 12 ]
  • Part A: Percentage of Participants With 15% or Greater Reduction in LDL-C From Baseline at Week 12 [ Time Frame: Baseline and Week 12 ]
    LDL-C was quantified using the ultracentrifugation method.

  • Part A: Change From Baseline in Proprotein Convertase Subtilisin/Kexin Type 9 (PCSK9) at Week 12 [ Time Frame: Baseline and Week 12 ]
  • Part B: Percent Change From Baseline in LDL-C at the Mean of Weeks 6 and 12 [ Time Frame: Baseline and Weeks 6 and 12 ]
    LDL-C was quantified using the ultracentrifugation method.

  • Part B: Percent Change From Baseline in Apolipoprotein B at Week 12 [ Time Frame: Baseline and Week 12 ]
  • Part B: Percent Change From Baseline in Apolipoprotein B at the Mean of Weeks 6 and 12 [ Time Frame: Baseline and Weeks 6 and 12 ]
  • Part B: Percent Change From Baseline in Lipoprotein (a) at Week 12 [ Time Frame: Baseline and Week 12 ]
  • Part B: Percent Change From Baseline in Lipoprotein (a) at the Mean of Weeks 6 and 12 [ Time Frame: Baseline and Weeks 6 and 12 ]
