Efficacy and Safety of Alirocumab (SAR236553/REGN727) Versus Placebo on Top of Lipid-Modifying Therapy in Patients With Heterozygous Familial Hypercholesterolemia Not Adequately Controlled With Their Lipid-Modifying Therapy (ODYSSEY FH I)

January 11, 2016 updated by: Sanofi

A Randomized, Double-Blind, Placebo-Controlled, Parallel Group Study to Evaluate the Efficacy and Safety of SAR236553/REGN727 in Patients With Heterozygous Familial Hypercholesterolemia Not Adequately Controlled With Their Lipid-Modifying Therapy

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

Study Overview

Detailed Description

The maximum study duration was planned to be 89 weeks per participant including participants who successfully completed the 78-week treatment period had the possibility to join an open-label extension study (LTS13463, NCT01954394) at the end of the treatment period.
