About this study

Official title: A Randomized, Double-Blind, Placebo-Controlled, Single Ascending Dose Study of the Safety, Tolerability, and Pharmacokinetics of REGN6490 in Healthy Japanese Volunteers

The primary objective of the study is to evaluate the safety and tolerability of 3 single ascending subcutaneous (SC) doses and 1 single intravenous (IV) dose of REGN6490 in healthy first-generation Japanese adult participants

The secondary objectives of the study are:

  • To characterize the pharmacokinetic (PK) profile of single SC and IV doses of REGN6490 in healthy first-generation Japanese adult participants
  • Assess immunogenicity of REGN6490 in healthy first-generation Japanese adult participants dosed with a single IV or SC dose of REGN6490
Being tested
REGN6490, Placebo

    TEAEs include abnormal laboratory testing, vital signs and electrocardiograms (ECGs)

    Measured: Up to Week 16

Secondary outcomes (2)
  1. Serum Concentration of REGN6490 over time

    Measured: Up to Week 16

  2. Incidence of Treatment-Emergent REGN6490 Anti-Drug Antibodies (ADAs)

    Measured: Up to Week 16

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing REGN6490 in people with Healthy Volunteer, run by Regeneron Pharmaceuticals at 1 site in United States.

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 6 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: stopped early, as of the sponsor's last update on 11 Nov 2021. 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 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 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 was stopped early (reason given: Sponsor decision). Results are not available in the source record.

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 and severity of Treatment-Emergent Adverse Events (TEAEs) (time frame: Up to Week 16). 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 11 Nov 2021.
