Phase II Randomized, Double-Blind Study of Nebulized Ensifentrine vs Placebo in Adults With Non-Cystic Fibrosis Bronchiectasis

What this Trial Is About

Researchers are evaluating the effects of ensifentrine inhalation suspension compared to a placebo in adults with non-cystic fibrosis bronchiectasis NCFBE. This study aims to understand how ensifentrine, added to standard care, impacts lung flare-ups, symptoms, and quality of life. It is a randomized, double-blind, placebo-controlled Phase II trial designed to assess both efficacy and safety over up to 52 weeks. Participants will be randomly assigned to receive either 3 mg of nebulized ensifentrine or a placebo, both delivered twice daily using a standard jet nebulizer. The treatment period may last up to 52 weeks, although the study may end earlier once the last participant completes 24 weeks. Neither participants nor study staff will know which treatment is administered during the study. During the study, participants will be monitored regularly, including assessments of lung function, respiratory symptoms, quality of life, and tracking of any pulmonary exacerbations. Measurements will be taken at baseline and at various time points up to 52 weeks. Safety will be evaluated through adverse event tracking. The primary outcome focuses on the rate of pulmonary exacerbations per year, with additional assessments of symptom changes and lung function.
