- Brief 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 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
- 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.

Group Intervention Description Placebo Placebo (for alirocumab) Placebo for alirocumab every 2 weeks (Q2W) on top of stable lipid-modifying therapy (LMT) for 78 weeks. Placebo Lipid Modifying Therapy (LMT) Placebo for alirocumab every 2 weeks (Q2W) on top of stable lipid-modifying therapy (LMT) for 78 weeks. Alirocumab 75 mg/Up to 150 mg Q2W Alirocumab Alirocumab 75 mg Q2W on top of stable LMT for 78 weeks. Alirocumab dose up-titrated to 150 mg from Week 12 when low-density lipoprotein cholesterol (LDL-C) levels ≥ 70 mg/dL (1.81 mmol/L) at Week 8. Alirocumab 75 mg/Up to 150 mg Q2W Lipid Modifying Therapy (LMT) Alirocumab 75 mg Q2W on top of stable LMT for 78 weeks. Alirocumab dose up-titrated to 150 mg from Week 12 when low-density lipoprotein cholesterol (LDL-C) levels ≥ 70 mg/dL (1.81 mmol/L) at Week 8.
- Primary Outcome Measures
Name Time Method Percent Change From Baseline in Calculated LDL-C at Week 24 - Intent-to-Treat (ITT) Analysis From Baseline to Week 52 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).
