A Phase 1a/1b Study to Investigate the Safety, Tolerability, Microbiological Response, and Pharmacokinetics of Inhaled Rev-56 in Adult Healthy Volunteers and Adult Non-cystic Fibrosis Bronchiectasis (NCFB) Patients With Chronic P. Aeruginosa
What this study is about
This is a Phase 1a/1b study to test the safety, tolerability, microbiological response, and how the drug moves through the body of inhaled Rev-56 compared to placebo in adult healthy participants and non-cystic fibrosis bronchiectasis (NCFB) patients with P. aeruginosa, respectively.
View original scientific description
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.

Frequently asked questions
What is a clinical trial?
A clinical trial is a research study that tests new medical treatments, drugs, devices, or procedures to determine their safety and effectiveness. Trials are carefully designed and monitored to protect participants while advancing medical knowledge.
Is it safe to participate?
Clinical trials follow strict safety guidelines and ethical standards. Trials must be reviewed and approved, and participants are closely monitored by medical professionals throughout the study. You can withdraw at any time if you choose.
Will I be compensated?
Many clinical trials offer compensation for your time, travel expenses, and inconvenience. The specific compensation varies by study and will be discussed during the screening process. All study-related medical care is typically provided at no cost to participants.
Will I receive a placebo instead of treatment?
When effective treatment exists, participants typically receive either the standard treatment plus the study intervention, or the standard treatment plus placebo. You would not be denied effective care. Placebos are primarily used when no proven treatment is available, or in addition to standard care. Your trial consent form will clearly explain what treatments you may receive.
Can I leave a trial if I change my mind?
Absolutely. Participation in clinical trials is completely voluntary. You have the right to withdraw from the study at any time, for any reason, without penalty or loss of benefits to which you are otherwise entitled.
How long does a clinical trial last?
Trial duration varies widely depending on the study design and purpose. Some trials last just a few weeks, while others may continue for months or years. The study coordinator will provide specific timeline information during your screening call.
