Purpose: Chronic rhinosinusitis with nasal polyps (CRSwNP) is a predominantly type 2 inflammatory disease frequently coexisting with other type 2 conditions including asthma and non-steroidal anti-inflammatory drug-exacerbated respiratory disease (NSAID-ERD). Coexisting asthma leads to increased CRSwNP symptom burden. Dupilumab, a monoclonal antibody that blocks the shared receptor component for interleukin-4 and-13, demonstrated efficacy in adults with severe CRSwNP in the Phase 3 SINUS-24 (NCT02912468) and SINUS-52 (NCT02898454) studies, including in patients with coexisting asthma/NSAID-ERD. However, the impact of different asthma characteristics on dupilumab treatment in this population is unknown. We report CRSwNP and asthma outcomes with dupilumab in patients with CRSwNP and coexisting asthma according to baseline asthma characteristics. Methods: Change from baseline at Week 24 (pooled studies) and Week 52 (SINUS-52) in CRSwNP outcomes (nasal polyp score, nasal congestion, 22-item Sino-Nasal Outcome Test [SNOT-22], loss of smell score, University of Pennsylvania Smell Identification Test) and asthma outcomes (5-item Asthma Control Questionnaire [ACQ-5], pre-bronchodilator forced expiratory volume in 1 second [FEV1 ]) were analyzed post hoc for placebo and dupilumab 300 mg every 2 weeks according to baseline blood eosinophils ≥150/≥300 cells/µL, ACQ-5 scores <1.5/≥1.5, and FEV1 <80%. Results: In the pooled studies, 428/724 patients (59.1%) had coexisting asthma, of which 181/428 (42.3%) had coexisting NSAID-ERD. Dupilumab significantly improved all CRSwNP and asthma outcomes vs placebo at Week 24 (P < 0.001) regardless of baseline eosinophil or ACQ-5 category, or FEV1 <80%. Similar magnitude of improvement was seen at Week 52 (SINUS-52) and in patients with NSAID-ERD (pooled studies, Week 24). By Week 24, improvements with dupilumab exceeded the minimum clinically important differences for ACQ-5 and SNOT-22 in 35.2% to 74.2% and 72.0% to 78.7% of patients, respectively. Conclusion: Dupilumab improved CRSwNP outcomes in patients with CRSwNP and coexisting asthma, and improved asthma outcomes, regardless of differences in baseline asthma characteristics.
