    This outcome measure evaluated the percent change from baseline to Day 180 in cholesterol (total, high-density lipoprotein [HDL], non-HDL) and apolipoproteins (B, A1) in participants (single and double dose) in the mITT population.

  8. Number of Participants Who Attained Global Lipid Modification Targets for Level of Atherosclerotic Cardiovascular Disease Risk [ Time Frame: Baseline, Day 180 ]

    This outcome measure evaluated the proportion of participants (single and double dose) in the mITT population who attained a global lipid modification target by baseline cardiovascular risk group, looking specifically at LDL-C levels (mg/dL) in the category of cardiovascular disease (CVD).

    CVD was defined as a participant who had at least 1 of the following: prior myocardial infarction, prior percutaneous coronary intervention, prior coronary artery bypass graft, prior stroke, prior transient ischemic attack, peripheral artery disease.

  3. Serum LDL-C ≥1.8 millimole (mmol)/liter (L) (≥70 mg/dL) for ASCVD participants or ≥2.6 mmol/L (≥100 mg/dL) for ASCVD-risk equivalent participants at screening.
  4. Fasting triglyceride <4.52 mmol/L (<400 mg/dL) at screening.

    • Unlikely to comply with the protocol requirements, instructions, and study-related restrictions (for example, uncooperative attitude, inability to return for follow-up visits, and improbability of completing the study).
    • Have any medical or surgical condition, which in the opinion of the investigator would put the participants at increased risk from participating in the study.
