About this trial
This study will evaluate the safety and effects of ALX1, an inhaled investigational treatment, in adults with bronchiectasis. Participants will receive either ALX1 or a placebo (a treatment with no active medicine) for 14 days. The study will compare different dose levels of ALX1 to help identify appropriate doses for future research based on safety, tolerability, and changes in predictive biomarkers.
Eligibility criteria
Qualifiers

FEV1 ≥ 40% of predicted values at Screening.
Disqualifiers
Negative sputum NEATstik result for neutrophil elastase at Pre-screening.
