Homozygous Familial Hypercholesterolemia

Brief summary

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

Participant flow

Recruitment details

Participants were recruited from 27 centers in 13 countries around Europe, Asia, South Africa, and North America. A total of 85 participants were screened. Of those,16 were considered screen failures (mainly due to violations of inclusion/exclusion criteria).

Pre-assignment details

Sixty-nine of the 85 participants were eligible and randomized in a 2:1 ratio to receive either alirocumab 150 mg SC Q2W or matching placebo. Randomization was stratified by LDL apheresis treatment status (on vs off treatment).
