An Efficacy and Safety Study of Alirocumab in Children and Adolescents With Heterozygous Familial Hypercholesterolemia

Registration Number
NCT03510884
Lead Sponsor
Sanofi
Brief Summary

Primary Objective:

To evaluate the efficacy of alirocumab administered every 2 weeks (Q2W) and every 4 weeks (Q4W) versus placebo after 24 weeks of double-blind (DB) treatment on low-density lipoprotein cholesterol (LDL-C) levels in participants with heterozygous familial hypercholesterolemia (heFH) 8 to 17 years of age on optimal stable daily dose of statin therapy ± other lipid modifying therapies (LMTs) or a stable dose of non-statin LMTs in case of intolerance to statins.

Secondary Objectives:

* To evaluate the efficacy of alirocumab versus placebo on LDL-C levels.

* To evaluate the effects of alirocumab versus placebo on other lipid parameters.

* To evaluate the safety and tolerability of alirocumab in comparison with placebo.

* To evaluate the efficacy, safety, and tolerability of alirocumab after open label treatment.

* To evaluate the development of anti-alirocumab antibodies.

Detailed Description

The study duration was approximately up to 110 weeks (run-in period \[if needed\]: up to 4 weeks \[+2 days\], screening period: up to 2 weeks \[+5 days\], double-blind treatment period: 24 weeks, open label (OL) treatment period: 80 weeks).

Change From Baseline in Cogstate Battery Test - Overall Composite Score at Weeks 24, 68 and 104Baseline, Weeks 24, 68 and 104

Cogstate battery test (cognitive testing system) consisted of detection test (DET), identification test (IDN), one card learning test (OCL) and Groton maze learning test (GML) to assess processing speed, attention, visual learning and executive functioning, respectively. For each test, Z-scores were computed based on participant's age at Baseline and Weeks 24, 68 and 104. Composite score: calculated as mean of Z-scores equally weighted, provided that at least 3 of 4 tests were available and if all of these domains were covered as: attention, through either DET or IDN, visual learning, through OCL and executive function, through GML. There is not minimum/maximum since values were reported as z-score but z-score of 0 means result equals to mean with negative numbers indicating values lower than mean and positive values higher. Positive change in z-score = an improvement in cognition, i.e., a better outcome; and negative change in z-score = worsening in cognition, i.e., a worse outcome.

Tanner stage defines physical measurements of development in children and adolescent based on external primary and secondary sex characteristics. Participants were evaluated for pubic hair distribution, breast development (only females) and genital development (only males) and classified in 3 categories as: Prepubescent (defined as a person just before start of the development of adult sexual characteristics), Pubescent (defined as a person at or approaching the age of puberty), Postpubescent (sexually mature or a person who has completed puberty).

DB Period: Number of Participants With Treatment-Emergent (TE) Positive Anti-Alirocumab Antibodies (ADA) ResponseUp to 24 weeks

Anti-drug (alirocumab) antibodies samples were analyzed using a validated non-quantitative, titer-based bridging immunoassay. Number of participants with positive ADA during 24-week treatment period is reported. Treatment-emergent positive ADA response was defined as 1) participants with no ADA positive response at baseline but with any positive response in the post-baseline period or 2) participants with a positive ADA response at baseline and at least a 4- fold increase in titer in the post-baseline period. A persistent positive response was defined as a TE ADA positive response detected in at least 2 consecutive post-baseline samples separated by at least a 12-week period. Persistent positive response was only analyzed for participants with positive TE ADA response.
