研究概览
简要总结
The primary objective of the study is to demonstrate the reduction of low-density lipoprotein cholesterol (LDL-C) with alirocumab subcutaneous (SC) every 2 weeks (Q2W) in comparison to placebo after 12 weeks of treatment.
The secondary objectives of the study are:
- To evaluate the effect of alirocumab Q2W on other lipid parameters (ie, apolipoprotein [Apo] A-1 and B, non-high-density lipoprotein cholesterol [non-HDL-C], total-cholesterol [TC], proportion of participants with 15%, 30%, and 50% LDL-C reductions, Lp(a), HDL-C, triglycerides [TG]) in participants with HoFH
- To evaluate the safety and tolerability of alirocumab SC Q2W in participants with HoFH
- To assess the pharmacokinetics of alirocumab SC Q2W in participants with HoFH
- To assess the potential development of anti-drug (alirocumab) antibodies

排除标准
- •Documented evidence of a null mutation in both LDLR alleles
- •Use of a PCSK9 inhibitor within 10 weeks from screening visit
- •Background medical lipid modifying therapy (LMT) that has not been stable for at least 4 weeks (6 weeks for fibrates, 24 weeks for mipomersen, 12 weeks for maximum tolerated dose of lomitapide) before the screening visit.
- •LDL apheresis schedule/apheresis settings that have not been stable for at least 8 weeks before the screening visit or an apheresis schedule/settings that is not anticipated to be stable over the next 24 weeks.
