BRINSUPRI was studied in the largest clinical trial in bronchiectasis1
ASPEN was a Phase 3 placebo-controlled trial2,3
The ASPEN study was an international, multicenter, randomized, double-blind, parallel-group, placebo-controlled Phase 3 clinical trial. Patients were 12 to 85 years of age (41 adolescents and 1680 adults) and received 1 of 2 doses of BRINSUPRI (10 mg: n=583; 25 mg: n=575) or placebo (n=563), administered once daily for 52 weeks.2,3
Patients in all arms were permitted to continue using their existing concomitant therapy.3,4


All patients enrolled in ASPEN had a clinical history of confirmed non-cystic fibrosis bronchiectasis (NCFB) by chest computed tomography (CT). Adult patients had at least 2 documented pulmonary exacerbations prior to screening in the prior 12 months. Adolescent patients had at least 1 pulmonary exacerbation in the prior 12 months.2,3
WILLOW was a Phase 2 placebo-controlled trial2,5
WILLOW was a randomized, double-blind, placebo-controlled, parallel-group, multicenter, multinational Phase 2 clinical trial with 256 patients. Adults with NCFB received either BRINSUPRI (10 mg, 25 mg) or placebo once daily for 24 weeks.2,5


Demographic and baseline characteristics of patients in ASPEN and WILLOW2,3,7
Patient characteristics in ASPEN were representative of real-world populations of patients with bronchiectasis.
