About this study

Official title: A Phase 1, Randomized, Double-Blind, Placebo-Controlled Study to Evaluate the Safety, Tolerability, Pharmacokinetics, and Pharmacodynamics of Single Ascending Doses of REGN7544, an Antagonistic Monoclonal Antibody to NPR1, in Healthy Adults

The study is researching an experimental drug called REGN7544.The study is focused on healthy adults. The aim of the study is to see how safe and tolerable the study drug is in healthy adults.

The study is looking at several other research questions, including:

  • What side effects may happen from taking the study drug
  • How much study drug is in your blood at different times
  • Whether the body makes antibodies against the study drug (which could make the drug less effective or could lead to side effects)
Being tested
REGN7544, Matching Placebo
Keywords
Hypotension and/or hypovolemia

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing REGN7544 in people with Healthy Volunteers, run by Regeneron Pharmaceuticals at 1 site in New Zealand.

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 6 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 12 Aug 2024. 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 New Zealand. 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?

Incidence of Treatment Emergent Adverse Events (TEAEs) (time frame: Through approximately day 162). The study lists 2 primary outcomes in all. 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 12 Aug 2024.
