About this study

Official title: A Phase 2 Pilot Study With a Randomized Double-Blind Treatment Phase to Evaluate the Pharmacodynamics and Safety of Alirocumab in Patients With Autosomal Dominant Hypercholesterolemia and Gain-of-Function Mutations in 1 or Both Alleles of the PCSK9 Gene or Loss-of-Function Mutations in 1 or More Alleles of the Loss-of-Function Mutations B Gene

What is being measured

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

  1. Percent Change in Measured Serum Low-Density Lipoprotein Cholesterol (LDL-C) From Baseline to Day 15

    By day 15, participants in groups A and C had received 1 subcutaneous (SC) dose of 150 mg alirocumab and participants in group B and D had received 1 SC dose of placebo. [Baseline adjusted least squares (LS) means and standard errors were obtained using analysis of covariance (ANCOVA) model specifying the treatment arm as the fixed effect and the baseline measured LDL-C value as a covariate.]

    Measured: Baseline to Day 15

Secondary outcomes (4)
  1. Percent Change in Apolipoprotein (Apo) B100 From Baseline to Day 15

    Baseline adjusted LS means and standard errors were obtained using the same ANCOVA model as for primary endpoint specifying the treatment arm as the fixed effect and the parameter value as a covariate.

    Measured: Baseline to Day 15

  2. Percent Change in Non High-Density Lipoprotein Cholesterol (Non-HDL-C) From Baseline to Day 15

    Measured: Baseline to Day 15

  3. Percent Change in Total Cholesterol (Total-C) From Baseline to Day 15

    Measured: Baseline to Day 15

  4. Percent Change in Apolipoprotein (Apo) B100/ ApoA-1 Ratio From Baseline to Day 15

    Measured: Baseline to Day 15

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing Alirocumab in people with Hypercholesterolemia, run by Regeneron Pharmaceuticals at 4 sites in 2 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 4 inclusion and 5 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 17 Jun 2020. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 4 sites in France, United States. 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 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.

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 17 Jun 2020). 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 Measured Serum Low-Density Lipoprotein Cholesterol (LDL-C) From Baseline to Day 15 (time frame: Baseline to Day 15). 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 NCT01604824, 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 17 Jun 2020.
