About this study

Official title: A Randomized, Double-Blind, Placebo- and Active-Controlled, 3-Way Crossover Study in Healthy Subjects to Determine the Effect of Omaveloxolone on QTc Interval

This is a randomized, double blind, placebo and active (moxifloxacin open label) controlled study in healthy subjects to assess the effect of the supratherapeutic exposure of omaveloxolone on QTc interval. Moxifloxacin will be used as an active control and will be administered as open label. Omaveloxolone and placebo will be administered in a blinded fashion. All treatments will be administered after an FDA high-fat meal. Concentration-QTc (C-QTc) analysis is the primary analysis for the study.

Being tested

What is being measured

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

  1. Change from baseline in placebo-corrected QTcF (∆∆QTcF)

    The relationship between ∆QTcF and omaveloxolone and its metabolites, M17 and M22 plasma concentrations will be investigated by a linear mixed effects modeling approach with ∆ QTcF as the dependent variable, time-matched concentration of omaveloxolone and its metabolites as a continuous covariate (ie, 0 for placebo), and centered baseline QTcF as an additional covariate, treatment (active = 1; or placebo = 0) and time as categorical factors, and a random intercept and slope per subject.

    Measured: At Day 1 of each period, which is 14 days for both Treatment A and Treatment B and 4 days for Treatment C

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing Omaveloxolone and Moxifloxacin in people with Health Adult Subjects, run by Biogen 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 4 inclusion and 21 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 30 May 2025. 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 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?

Change from baseline in placebo-corrected QTcF (∆∆QTcF) (time frame: At Day 1 of each period, which is 14 days for both Treatment A and Treatment B and 4 days for Treatment C). 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 NCT05927649, which also lists 1 linked publication.

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 30 May 2025.
