Alirocumab (SAR236553/REGN727) is a fully human monoclonal antibody that binds PCSK9 (proprotein convertase subtilisin/kexin type 9). Primary Objective of the study: To demonstrate the reduction of low-density lipoprotein cholesterol (LDL-C) by alirocumab as add-on therapy to stable maximally tolerated daily statin therapy in comparison with ezetimibe after 24 weeks of treatment in participants with hypercholesterolemia at high cardiovascular (CV) risk. Secondary Objectives: * To evaluate the effect of alirocumab in comparison with ezetimibe on LDL-C at other time points * To evaluate the effect of alirocumab on other lipid parameters * To evaluate the safety and tolerability of alirocumab
The maximum study duration was 115 weeks per participant, including a 3-week screening period, 104-week randomized treatment period and 8-week follow-up period.

Percent Change From Baseline in Calculated LDL-C at Week 24 - Intent-to-treat (ITT) Analysis
Adjusted Least-squares (LS) means and standard errors at Week 24 were obtained from a mixed-effect model with repeated measures (MMRM) to account for missing data. All available post-baseline data from week 4 to week 52 regardless of status on- or off-treatment were used in the model (ITT analysis).
Time frame: From Baseline to Week 52
Percent Change From Baseline in Calculated LDL--C at Week 24 - On--Treatment Analysis
Adjusted LS means and standard errors at Week 24 were obtained from MMRM model including available post-baseline on-treatment data from Week 4 to Week 52 (i.e. up to 21 days after last injection or 3 days after the last capsule, whichever came first).
Time frame: From Baseline to Week 52
Percent Change From Baseline in Calculated LDL-C at Week 12 - ITT Analysis
