What is the study measuring?
-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Percentage of Participants Who Experience at Least 1 Adverse Event (AE) | An AE was any unfavorable and unintended sign (including an abnormal laboratory finding), symptom, or disease temporally associated with use of a medicinal product, regardless of whether or not it was considered related to the medicinal product. The percentage of participants who reported at least 1 AE was summarized. | Up to 2 weeks post last dose of study drug (up to 54 weeks) | 
| Percentage of Participants Who Had Study Drug Discontinued Due to an AE | An AE was any unfavorable and unintended sign (including an abnormal laboratory finding), symptom, or disease temporally associated with use of a medicinal product, regardless of whether or not it was considered related to the medicinal product. The percentage of participants who had study drug discontinued due to an AE was summarized. | up to 52 weeks | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Percentage Change From Baseline in Low-Density Lipoprotein-Cholesterol (LDL-C) | Blood was collected at baseline (predose) and after 52 weeks of treatment to determine LDL-C levels. LDL-C was calculated using the Friedewald equation. If triglycerides (TG) exceeded 400 mg/dL (4.6 mmol/L), LDL-C was determined by beta quantification ultracentrifugation. The percentage change from baseline at Week 52 was summarized. | Baseline (predose) and Week 52 |
