Lung function improvement was seen as early as Week 2 and sustained through
Week 52
Post-bronchodilator FEV1
Change in post‑bronchodilator FEV1 from baseline at Week 12 and Week 52 (ITT population; secondary endpoint)1
Pre-bronchodilator FEV1
Significant improvements of similar magnitude were observed in change from baseline in pre-bronchodilator FEV1 at Weeks 12 and 52 in subjects treated with DUPIXENT compared to placebo across the BOREAS and NOTUS trials.1
Patients administered DUPIXENT + triple therapy saw numerical improvement in post‑bronchodilator FEV1 of 134 mL at Week 12 (n=470) and 127 mL at Week 52 (n=362), compared with 67 mL at Week 12 (n=465) and 59 mL at Week 52 (n=359) in patients receiving placebo + triple therapy (LSM change from baseline, ITT population).1
Post-bronchodilator lung function results are descriptive. Definitive conclusions cannot be made.
