Study in Participants With Homozygous Familial Hypercholesterolemia (HoFH)
NCT03156621 · View on ClinicalTrials.gov ↗
Study 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

Full Details on ClinicalTrials.gov ↗What the Registry Record Tells You About NCT03156621
The ClinicalTrials.gov registry entry for NCT03156621 describes a study currently listed as completed. It is categorized as Phase 3, which is the standard way researchers label where a study sits along the investigational pathway from early safety work through later efficacy and post-marketing evaluation. The registered enrollment target is 69 participants, a figure that helps gauge the scale of data the investigators plan to collect. The listed sponsor is Regeneron Pharmaceuticals, which has 290 total studies on file at ClinicalTrials.gov, and sponsors are the parties responsible for study design, oversight, and regulatory filings.
The record links to 1 condition, with Homozygous Familial Hypercholesterolemia appearing as the primary indexed condition, and to 2 interventions — of which Placebo is the first listed. Interventions can include drugs, devices, procedures, behavioral programs, or observational arms, and each is tracked as a separate registry field so that downstream queries can filter accurately. When a trial lists multiple interventions, it usually reflects a multi-arm design or a comparison protocol rather than a single treatment being tested in isolation. The brief summary published in the registry is the clearest source of protocol intent and should be read before drawing conclusions from any sidebar tags.
Geographic footprint matters for practical reasons: NCT03156621 reports 20 study locations spanning 12 distinct geographic areas — top geographies include Other, Quebec, Florida. A larger site network tends to correlate with broader recruitment capacity, but it does not imply anything about study quality, and site-level enrollment status can diverge from the overall registry status shown above. Every data point on this page comes from the public ClinicalTrials.gov dataset and is reproduced here for reference only; it is not a medical recommendation, an endorsement of the sponsor, or an invitation to enroll.
