Pre-assignment details
The Screening Period occurred no more than 70 days and no less than 7 days prior to the first dose of study drug. The up to 10-week Screening Period allowed for a 6-week washout period, if needed, followed by an up to 4-week Qualification Period that was used to assess patient eligibility. Prior to treatment on Day 1, eligible patients were randomized in a 1:1:1 ratio to 1 of 3 treatment groups. Randomization was stratified by sex, statin use, and PK assessment.
