Change From Baseline in Cogstate Battery Test - Overall Composite Score at 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.
Measured: Baseline, Weeks 24, 68 and 104
Number of Participants With Tanner Staging at Baseline and Weeks 24, 68 and 104
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).
Measured: Baseline, Weeks 24, 68 and 104
DB Period: Number of Participants With Treatment-Emergent (TE) Positive Anti-Alirocumab Antibodies (ADA) Response
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.
Measured: Up to 24 weeks

Clinical summary
The research question as the sponsor registered it. This describes what the study plans to test, not what it found.
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).

DB Period: Percent Change From Baseline in Low Density Lipoprotein Cholesterol (LDL-C) at Week 24: Intent-to-treat (ITT) Estimand
Time frame: Baseline, Week 24
Adjusted least square (LS) means and standard errors (SE) were obtained from mixed-effect model with repeated measures (MMRM) model. All post-baseline data available up to Week 24 were used and missing data were accounted for by the MMRM model. MMRM model was run on participants with a Baseline value and a post-baseline value for at least one timepoint used in the model.

Questions about this trial
What is this clinical trial studying?
A Phase 3 study testing Alirocumab SAR236553 (REGN727), Rosuvastatin and Atorvastatin in people with Hypercholesterolaemia, run by Sanofi at 43 sites in 24 countries.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 5 inclusion and 13 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: finished, as of the sponsor's last update on 6 May 2023. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 43 sites in United States, Russia, Spain, Italy, Brazil and 19 more countries. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
What does this phase mean?
Phase 3 studies compare the treatment with the current standard treatment or a placebo in a large group, to confirm how well it works and watch for side effects.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
Are results available for this study?
Yes. Results are posted in the registry (first posted 6 May 2023). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
DB Period: Percent Change From Baseline in Low Density Lipoprotein Cholesterol (LDL-C) at Week 24: Intent-to-treat (ITT) Estimand (time frame: Baseline, Week 24). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT03510884, which also lists 1 linked publication.
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 6 May 2023; AzTrials last refreshed its copy on 8 Nov 2026.
