Efficacy and Safety of Alirocumab (SAR236553/REGN727) Versus Placebo on Top of Lipid-Modifying Therapy in Patients With Heterozygous Familial Hypercholesterolemia (ODYSSEY HIGH FH)

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 effect of alirocumab on low-density lipoprotein cholesterol (LDL-C) levels after 24 weeks of treatment in comparison with placebo.

Secondary Objectives:

* 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 * To evaluate the safety and tolerability of alirocumab
