Long-term Safety and Tolerability of SAR236553 (REGN727) in High Cardiovascular Risk Patients With Hypercholesterolemia Not Adequately Controlled With Their Lipid Modifying Therapy: A Randomized, Double-Blind, Placebo-Controlled Study

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.
The maximum study duration was to be 89 weeks per participant, including a 3-week screening period, a 78-week randomized treatment period and 8-week follow-up period.
