Proven to significantly reduce exacerbation risk in bronchiectasis1,2
ASPEN study design
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 orally once daily for 52 weeks.1,2
Patients in all arms were permitted to continue using their existing concomitant therapy.2,3
Exacerbations
PRIMARY ENDPOINT
BRINSUPRI is proven to reduce the risk of bronchiectasis exacerbations1,2,a
BRINSUPRI 10 mg
21.1%
reduction in exacerbation risk over 52 weeks
Rate ratio vs placebo (95% Cl): 0.79 (0.68-0.92); P=0.004.b
BRINSUPRI 25 mg
19.4%
reduction in exacerbation risk over 52 weeks
Rate ratio vs placebo (95% Cl): 0.81 (0.69-0.94); P=0.005.b
BRINSUPRI demonstrated a significant reduction in exacerbation risk over 52 weeks
aAnnualized rate.1
bP value was adjusted for multiplicity.2
Annualized exacerbation rate: BRINSUPRI 10 mg: 1.02, BRINSUPRI 25 mg: 1.04, placebo: 1.29.
Pulmonary exacerbations were defined as a worsening of ≥3 major symptoms over 48 hours resulting in a physician’s decision to prescribe systemic antibiotics.1
SECONDARY ENDPOINT
BRINSUPRI prolonged the time to first exacerbation1,2,4
BRINSUPRI 10 mg
12-week
median delay vs placebo
Hazard ratio vs placebo (95% CI): 0.81 (0.70-0.95); P=0.02.c
BRINSUPRI 25 mg
14-week
median delay vs placebo
Hazard ratio vs placebo (95% CI): 0.83 (0.70-0.97); P=0.04.c
Time to patients’ first exacerbation in the study
cP value was adjusted for multiplicity.2
Time to first exacerbation (median weeks): BRINSUPRI 10 mg: 49.0, BRINSUPRI 25 mg: 50.7, placebo: 36.7.
SECONDARY ENDPOINT
Severe pulmonary exacerbations with BRINSUPRI vs placebo1,2
Pulmonary exacerbations were considered severe if they required treatment with IV antibacterial drugs and/or resulted in hospitalization.

Lung function
SECONDARY ENDPOINT
BRINSUPRI 25 mg significantly reduced lung function decline at Week 521,2
Placebo: Patients taking placebo in the trial had a 62-mL mean decline from baseline in post-BD FEV1 at Week 52
BRINSUPRI 10 mg
19%
less decline in post-BD FEV1 vs placebo at Week 52
Difference vs placebo (95% CI): 11 mL (-14 to 37); P=0.38.e
Results were not statistically significant.
BRINSUPRI 25 mg
61%
less decline in post-BD FEV1 vs placebo at Week 52
Difference vs placebo (95% CI): 38 mL (11-65); P=0.04.e
Mean change from baseline in post-BD FEV1 at Week 52
eP value was adjusted for multiplicity.2
