About this study
Official title: A Sequential, Phase 1a/1b, Double-blind, 2-part Study to Investigate the Safety, Tolerability, Microbiological Response, and Pharmacokinetics of Rev-56 for Inhalation Compared With Placebo in Healthy Adult Participants and Adult Non-cystic Fibrosis Bronchiectasis (NCFB) Patients With Chronic Pseudomonas Aeruginosa
This is a Phase 1a/1b study to test the safety, tolerability, microbiological response, and pharmacokinetics of inhaled Rev-56 compared to placebo in adult healthy participants and non-cystic fibrosis bronchiectasis (NCFB) patients with P. aeruginosa, respectively.
Phase 1a (Part A) will evaluate single doses of inhaled Rev-56 in adult healthy participants and includes up to 5 cohorts. Eligible participants will be randomized to active treatment or placebo in a 3:1 randomization scheme.
Phase 1b (Part B) will evaluate the safety, tolerability, microbiological response, and pharmacokinetics of multiple doses of inhaled Rev-56 in NCFB patients with P. aeruginosa and includes 2 cohorts evaluating once daily dosing and twice daily dosing, respectively. Eligible participants will be randomized to active treatment or placebo in a 2:1 randomization scheme.

Questions about this trial
What is this clinical trial studying?
A Phase 1 study testing Rev-56 for Inhalation in people with Healthy Participants and Non-cystic Fibrosis Bronchiectasis, run by Revagenix, Inc. 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 10 inclusion and 9 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: under way, not looking for participants, as of the sponsor's last update on 14 Oct 2026. 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?
This study is still under way. Results are not available in the source record yet.
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 (AEs) (time frame: 21 days (healthy participants) or 28 days (NCFB patients with P. aeruginosa)). 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 14 Oct 2026.
