Eligibility Criteria
Inclusion Criteria:
- Patient is a male, or a female who is unlikely to conceive, as indicated by meeting at least one of the following conditions: (a) Patient is a male.(b) Patient is a female of reproductive potential and either agrees to remain abstinent (if this form of birth control is accepted by local regulatory agencies and review committees as the sole method of birth control) or use (or have their partner use) 2 acceptable methods of birth control within the projected duration of the study.(c) Patient is a female who is not of reproductive potential and therefore eligible to participate in this study without requiring the use of contraception.
- Lipid-modifying therapy (LMT) is appropriate for the patient
- Patient meets one of the following criteria based on the National Cholesterol Education Program Adult Treatment Panel III guidelines : 1) High risk and is on a statin with LDL-cholesterol (LDL-C) <100 mg/dL or intolerant to statins with LDL-C <120 mg/dL; 2) Multiple risk with LDL-C <130 mg/dL; 3) Low risk with LDL-C <190 mg/dL

- Female patient plans to donate eggs during the study
- Male patient plans to donate sperm during the study
- Patient has or has a history of any condition, therapy, or lab abnormality that might confound the study results, interfere with participation for the full duration of the study, or make participation in the study not in the patient's best interest
- Patient has donated or received blood within 8 weeks of screening or plans to donate/receive blood during and 8 weeks after the study
- Patient is experiencing menopausal hot flashes

Outcomes
Primary Outcome Measures
Number Participants With Days Per Week With Global Flushing Severity Score (GFSS) ≥4 Partitioned Into 6 Categories During the Postwithdrawal Period
Flushing symptoms were recorded using participant's response to the Global Flushing Severity Score (GFSS), which assessed the overall severity of the flushing experience, using a scale of 0 (no symptom) to 10 (extreme). The number of days/week was derived as: 7*(total number of days with GFSS ≥4 across Weeks 21-32 divided by the total number of days with nonmissing GFSS across the same period). The number of days/week with a GFSS ≥4 for each participant was listed in 1 of the following 6 categories: 0, >0 to 0.5, >0.5 to 1, >1 to 2, >2 to 3, and >3 days per week.
Secondary Outcome Measures
Number of Participants With Maximum GFSS ≥4 During the Post-withdrawal Period
Flushing symptoms were recorded using participant's response to the Global Flushing Severity Score (GFSS), which assesses the overall severity of the flushing experience (including redness, warmth, tingling, or itching) using a scale with response categories of None, Mild, Moderate, Severe, and Extreme. The categories were supplemented with numbers 0 to 10 to allow for greater precision within each category (None=0, Mild=1-3, Moderate=4-6, Severe=7-9, Extreme=10). The daily response was recorded in the morning, and reflected the symptoms experienced during the previous 24 hours.
