Miami (August 12, 2026) – The Bronchiectasis and NTM Association today announced a collaboration with Insmed Incorporated, on a multicenter, prospective study designed to evaluate the real-world effectiveness, safety, and tolerability of brensocatib in adult patients with non-cystic fibrosis (non-CF) bronchiectasis.
The Brensocatib Effectiveness, Safety, and Tolerability in Bronchiectasis (BEST-BE) observational study is designed to measure the incidence and frequency of pulmonary exacerbations, or episodes of sudden worsening of respiratory symptoms, in adults 18 to 85 years old with non-CF bronchiectasis observed over a two-year period.
In addition, the study will track changes in participants’ health-related quality of life, and the incidence and frequency of adverse events. To deepen the evidence base for brensocatib, building on the landmark Phase 3 ASPEN study, the BEST-BE study will capture these data across a broad, diverse population of participants, including those with concurrent nontuberculous mycobacterial (NTM) lung infections and immunocompromised individuals.
