Condition	Hypercholesterolemia
Interventions	Drug: Alirocumab; Drug: Placebo (for alirocumab); Drug: Lipid Modifying Therapy (LMT)
Enrollment	486

Participant Flow

Recruitment Details	The study was conducted at 89 centers in 14 countries. A total of 597 participants were screened between July 2012 and April 2013, 111 of whom were screen failures.
Pre-assignment Details	Randomization was stratified according to prior history of myocardial infarction or ischemic stroke, intensity of statin treatment & geographic region. Assignment to treatment arms was done centrally using an Interactive Voice/Web Response System in 1:2 (placebo:alirocumab) after confirmation of selection criteria. 486 participants were randomized.

Adjusted percentages at Week 24 were obtained from multiple imputation approach for handling of missing data. All available post-baseline data from Week 4 to Week 52 regardless of status on- or off-treatment were included in the imputation model.
