Primary Objective:
To evaluate the effect of alirocumab (SAR236553/REGN727) on low-density lipoprotein cholesterol (LDL-C) levels compared with placebo when co-administered with 80 mg of atorvastatin after 8 weeks of treatment in participants with LDL-C ≥ 100mg/dL (≥ 2.59 mmol/L) on atorvastatin 10 mg.
Secondary Objectives:
- To evaluate the effects of alirocumab on other lipid levels in comparison with placebo, when co-administered with 80 mg of atorvastatin after 8 weeks of treatment.
- To evaluate the efficacy of alirocumab when co-administered with a high dose of atorvastatin (80 mg) versus atorvastatin 10 mg.
- To evaluate the safety and tolerability of alirocumab when co-administered with 2 different doses of atorvastatin.
- To evaluate the development of anti-alirocumab antibodies.
- To evaluate the pharmacokinetics of alirocumab.
Condition or disease | Intervention/treatment | Phase |
---|---|---|
Hypercholesterolemia | Drug: Alirocumab Drug: Placebo (for alirocumab) Drug: Atorvastatin Drug: Placebo (for atorvastatin) | Phase 2 |
The duration of study participation depended on the status of the patient at screening:
- For participants receiving atorvastatin 10 mg at stable dose for at least 6 weeks prior to screening, the study participation was to be approximately 17 weeks including a screening period of 1 week, a double-blind treatment period of 8 weeks and a follow-up period of 8 weeks.
- For participants receiving a lipid lowering treatment other than atorvastatin/ or not at stable dose of atorvastatin 10 mg for at least 6 weeks prior to screening, or drug naive participants, the study participation was to be approximately 23 weeks with a screening period of 1 week, a run-in treatment period with atorvastatin 10 mg of 6 weeks, a double-blind treatment period of 8 weeks and a follow-up period of 8 weeks.

- Percent Change From Baseline in Calculated LDL-C at Week 8 - On-treatment Analysis [ Time Frame: From Baseline to Week 8 (LOCF) ]Calculated LDL-C values were obtained using the Friedewald formula. Baseline adjusted least squares (LS) means and standard errors were estimated using an analysis of covariance (ANCOVA) model including available post-baseline data on treatment from first investigational product (IP) injection up to 21 days after last IP injection (on-treatment analysis). Missing Week 8 data were imputed by last observation carried forward [LOCF] method.
- Absolute Change From Baseline in Calculated LDL-C (mmol/L) at Week 8 - On-treatment Analysis [ Time Frame: From baseline to Week 8 (LOCF) ]Adjusted LS means and standard errors were estimated using the same ANCOVA model as for primary endpoint.
- Absolute Change From Baseline in Calculated LDL-C (mg/dL) at Week 8 - On-treatment Analysis [ Time Frame: From baseline to Week 8 (LOCF) ]Adjusted LS means and standard errors were estimated using the same ANCOVA model as for primary endpoint.
- Percentage of Participants Achieving Calculated LDL-C <100 mg/dL (2.59 mmol/L) and < 70 mg/dL (1.81 mmol/L) at Week 8 - On-treatment Analysis [ Time Frame: Week 8 (LOCF) ]
- Percent Change From Baseline in Total Cholesterol, Fasting Triglycerides, Non-high-Density Lipoprotein Cholesterol (Non-HDL-C), Apolipoprotein B (Apo-B) and Lipoprotein(a) at Week 8 - On-treatment Analysis [ Time Frame: From baseline to Week 8 (LOCF) ]Since the assumptions of normal distribution and equality of variances were not verified for the lipid parameters, percent changes were expressed as median (interquartile range).
- Percent Change From Baseline in High-Density Lipoprotein Cholesterol (HDL-C) at Week 8 - On-treatment Analysis [ Time Frame: From Baseline to Week 8 (LOCF) ]Adjusted LS means and standard errors were estimated using the same ANCOVA model as for primary endpoint.
- Absolute Change in the Ratio Apolipoprotein B/Apolipoprotein A-1 (ApoB/ApoA-1) From Baseline to Week 8 - On-treatment Analysis [ Time Frame: From Baseline to Week 8 (LOCF) ]Adjusted LS means and standard errors were estimated using the same ANCOVA as for primary endpoint.
