简要总结
Primary Objective:
To demonstrate the reduction of low-density lipoprotein cholesterol (LDL-C) by a regimen of Alirocumab including a starting dose of 150 mg every 4 weeks (Q4W) as add-on to non-statin lipid modifying background therapy or as monotherapy in comparison with placebo in participants with primary hypercholesterolemia not treated with a statin.
Secondary Objective:
- To evaluate the effects on other lipid parameters of Alirocumab 150 mg Q4W versus placebo.
- To evaluate the safety and tolerability of Alirocumab 150 mg Q4W.
Alirocumab 75 mg Q2W was added as a calibrator arm.
详细描述
The core study duration was approximately 35 weeks per participant (screening: 3 weeks, double-blind treatment period: 24 weeks; follow-up: 8 weeks). Participants who successfully completed the treatment period had the possibility to participate in an optional open-label treatment period with Alirocumab 150 mg Q4W until second quarter 2017 or until the drug is commercially available in the country, whatever occurred first.

研究组 & 干预措施
Placebo Q2W
Period 1: Placebo (for Alirocumab) subcutaneous (SC) injection every 2 weeks (Q2W) added to stable non-statin lipid modifying therapy (LMT) or diet alone for 24 weeks.
Period 2: Alirocumab 150 mg SC injection every 4 weeks (Q4W) from Week 24 until second quarter 2017 or until the drug is commercially available in the country, whatever occurred first. Alirocumab dose could be either up-titrated to 150 mg Q2W from Week 36 or maintained according to the investigator judgement and low-density lipoprotein cholesterol (LDL-C) values. Subsequent down titration to 150 mg Q4W was allowed.

Percent Change From Baseline in Calculated LDL-C at Week 24 - Intent-to-Treat (ITT Analysis)
时间窗: From Baseline to Week 24
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 24 regardless of status on- or off-treatment were used in the model (ITT analysis).
