Study Summary

Alirocumab (SAR236553/REGN727) is a fully human monoclonal antibody that binds PCSK9 (proprotein convertase subtilisin/kexin type 9). Primary Objective of the study: To evaluate the long-term safety and tolerability of alirocumab in high cardiovascular risk participants with hypercholesterolemia not adequately controlled with their current lipid modifying therapy (LMT). Secondary Objectives: * To evaluate the effect of alirocumab on low-density lipoprotein cholesterol (LDL-C) levels after 24 weeks of treatment in comparison with placebo. * To evaluate the effect of alirocumab in comparison with placebo on LDL-C at other time points. * To evaluate the effects of alirocumab on other lipid parameters.

Primary Outcome

Reported adverse events are treatment-emergent adverse events that is AEs that developed/worsened during the 'treatment-emergent period' (the time from the first dose of study drug up to the last dose of study drug +70 days).
