Efficacy and Safety of Alirocumab (SAR236553/REGN727) Versus Ezetimibe on Top of Statin in High Cardiovascular Risk Patients With Hypercholesterolemia (ODYSSEY COMBO II)
- Conditions
- Hypercholesterolemia
- Interventions
- Drug: Placebo (for alirocumab)Drug: Placebo (for ezetimibe)Drug: Lipid Modifying Therapy (LMT)
- Registration Number
- NCT01644188
- Lead Sponsor
- Sanofi
- 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 demonstrate the reduction of low-density lipoprotein cholesterol (LDL-C) by alirocumab as add-on therapy to stable maximally tolerated daily statin therapy in comparison with ezetimibe after 24 weeks of treatment in participants with hypercholesterolemia at high cardiovascular (CV) risk.
Secondary Objectives:
* To evaluate the effect of alirocumab in comparison with ezetimibe on LDL-C at other time points
* To evaluate the effect of alirocumab on other lipid parameters
* To evaluate the safety and tolerability of alirocumab
- Detailed Description
The maximum study duration was 115 weeks per participant, including a 3-week screening period, 104-week randomized treatment period and 8-week follow-up period.

- 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).
