Who can take part
You may be able to join if
- Participants must be 18 to 80 years of age inclusive, at the time of signing the informed consent
- Clinical history consistent with NCFB, such as chronic productive cough and/or recurrent respiratory infections
- Documented evidence of at least 2 PEx defined as episodes requiring a physician-prescribed course of antibiotics (oral and/or IV) for ≥5 days for signs and symptoms of respiratory infection within the 12 months prior to the Screening Visit
- Radiologic evidence of bronchiectasis, confirmed by a chest HRCT
- A minimum MPS of 4 (out of maximum 18) on chest HRCT performed before Baseline Visit
- Current sputum production with a documented history of chronic expectoration lasting ≥3 months within the previous 12 months
You likely can't join if
- A primary diagnosis of smoking-related COPD or asthma as determined by the Investigator. Participants with comorbid smoking-related COPD may be included if bronchiectasis is confirmed as their primary diagnosis and is the predominant cause of their respiratory symptoms
- Diagnosis of ABPA or any of the allergic bronchopulmonary mycoses
- Active NTM pulmonary disease currently requiring or receiving antimycobacterial treatment, or history of NTM pulmonary disease with incomplete treatment. Participants with NTM identified at Screening in association with symptoms or radiological findings warranting therapeutic evaluation according to ATS/IDSA criteria are also excluded
- Bronchiectasis due to any of the following: CF, CVID, AAT or PCD
- History of significant hemoptysis (requiring medical intervention and/or requiring blood transfusion)
- Current tobacco smokers
