About this study

Official title: A Randomized, Double-blind, Placebo-controlled, Parallel-group Study to Evaluate the Efficacy and Safety of Evinacumab in Patients With Homozygous Familial Hypercholesterolemia

The primary objective of the study is to demonstrate the reduction of low-density lipoprotein cholesterol (LDL-C) by evinacumab intravenously (IV) in comparison to placebo after 24 weeks in patients with homozygous familial hypercholesterolemia (HoFH). The secondary objectives of the study are to evaluate the effect of evinacumab IV on other lipid parameters, evaluate the effect of evinacumab on LDL-C goal attainment, assess the effect of evinacumab on eligibility for apheresis (using German and US apheresis criteria), evaluate the safety and tolerability of evinacumab in patients with HoFH, assess the pharmacokinetics (PK) of evinacumab in patients with HoFH and evaluate the potential development of anti-evinacumab antibodies.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Percent Change in Calculated Low-Density Lipoprotein Cholesterol (LDL-C) From Baseline to Week 24 (Intent-to-Treat [ITT] Estimand)

    Percent change was calculated as 100x(calculated LDL-C value at Week 24 - calculated LDL-C value at baseline)/calculated LDL-C value at baseline. The baseline LDL-C value was the last calculated LDL-C value obtained before the first dose of double-blind-study drug. The calculated LDL-C at week 24 was the LDL-C value obtained within the week 24 efficacy analysis window, regardless of adherence to treatment and subsequent therapies (intent-to-treat [ITT] estimand). The ITT population included all randomized participants who received at least one dose or part of a dose of double-blind study drug. Participants in the ITT population were analyzed according to the treatment group allocated by randomization (i.e., as randomized participant group).

    Measured: Week 24

Questions about this trial

What is this clinical trial studying?

A Phase 3 study testing evinacumab in people with Homozygous Familial Hypercholesterolemia, run by Regeneron Pharmaceuticals at 30 sites in 11 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 3 inclusion and 11 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 18 May 2021. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 30 sites in United States, Japan, Ukraine, Australia, Canada and 6 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 18 May 2021). 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?

Percent Change in Calculated Low-Density Lipoprotein Cholesterol (LDL-C) From Baseline to Week 24 (Intent-to-Treat [ITT] Estimand) (time frame: 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 NCT03399786, which also lists 2 linked publications.

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 18 May 2021.
