This study is to evaluate an investigational study drug, itepekimab, for the treatment of bronchiectasis. The main purpose for this study is to assess the safety, efficacy, and tolerability of itepekimab in bronchiectasis in addition to the current background treatment you are receiving which may include bronchodilators, inhaled corticosteroids, mucolytics, and/or maintenance antibiotics. You will receive either the study drug or a placebo if you participate in this research. This study will include about 300 participants with bronchiectasis across approximately 20 countries worldwide.

This research seeks to gather important insights about patients' experiences of NCFBE-related exacerbations and brensocatib treatment by conducting semi-structured qualitative interviews in the USA. A total of up to 30 interviews of approximately one hour are planned. Patient must be at least 18 years old and currently participating in the brensocatib PTA program for at least 3 months.

This is a Phase 2, double-blind, randomized, placebo-controlled study to evaluate the safety, tolerability, and efficacy of AP-PA02 administered by inhalation. This study will evaluate AP-PA02 administration in stable NCFB (non-cystic fibrosis bronchiectasis) patients. Subjects will either be included in Cohort A or Cohort B. For Cohort A, subjects will be randomized to receive either inhaled AP-PA02 or placebo. Cohort A will include individuals with NCFB and confirmed chronic P. aeruginosa infection but not on chronic inhaled antibiotics. These individuals will receive wither AP-PA02 or placebo for 10 days twice a day.
Cohort B will include individuals who with NCFB and confirmed P. aeruginosa infection but who are on chronic antibiotics. These individuals will receive either AP-PA02 or placebo for 10 days plus their current inhaled antibiotics for 28 days.
