About this study

Official title: A Phase 1 Randomized, Double-Blind, Placebo-Controlled, 2-Part Study to Assess the Safety and Tolerability, Pharmacokinetics, And Pharmacodynamics of Single and Multiple Doses of REGN4461 in Healthy Subjects

The primary objective of the study is to evaluate the safety and tolerability of REGN4461 in healthy participants. The secondary objectives of the study are to:

  • Characterize the Pharmacokinetic (PK) profile of single and repeated doses of REGN4461 and evaluate the effects of baseline covariates on PK profile
  • Estimate the effects of repeated doses of REGN4461 on body weight over 12 weeks in overweight and obese participants
  • Assess the effects of repeated doses of REGN4461 on ad lib energy intake in overweight and obese participants
  • Evaluate the effects of single and repeated doses of REGN4461 on soluble forms of lipid-regulating proteins levels over time
  • Assess the immunogenicity of single and repeated doses of REGN4461
Read the detailed description

This is a 2-part study of the safety, tolerability, PK and pharmacodynamic (PD) of single and repeated doses of REGN4461 in healthy participants. In Part A, healthy lean or overweight participants will be enrolled to evaluate the safety, tolerability, PK, and PD of single ascending intravenous (IV) and subcutaneous (SC) doses. Interim PK and safety information from Part A will be used to select the dose level, frequency, and mode of administration (IV or SC) for repeat dosing in Part B. In Part B, overweight/obese participants with body mass index (BMI) 25-40 kg/m2 will be enrolled to evaluate the safety, tolerability, PK, and PD of repeated doses of REGN4461 in 4 distinct cohorts defined by baseline leptin levels.

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing REGN4461 in people with Healthy Volunteers, run by Regeneron Pharmaceuticals at 1 site in Belgium.

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 8 inclusion and 20 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 9 Mar 2020. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in Belgium. 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 1 studies test a treatment in a small group of people for the first time or in a new way, mainly to check safety and find the right dose.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

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?

Number of treatment-emergent adverse events (TEAEs) (time frame: Up to week 27). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
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 9 Mar 2020.
