Efficacy and safety of dupilumab in patients with uncontrolled severe chronic rhinosinusitis with nasal polyps and a clinical diagnosis of NSAID‐ERD: Results from two randomized placebo‐controlled phase 3 trials

Background About one‐tenth of patients with difficult‐to‐treat chronic rhinosinusitis with nasal polyps (CRSwNP) have comorbid non‐steroidal anti‐inflammatory drug‐exacerbated respiratory disease (NSAID‐ERD). Dupilumab, a fully human monoclonal antibody that blocks the shared interleukin (IL)‐4/IL‐1...

Description
Summary:Background About one‐tenth of patients with difficult‐to‐treat chronic rhinosinusitis with nasal polyps (CRSwNP) have comorbid non‐steroidal anti‐inflammatory drug‐exacerbated respiratory disease (NSAID‐ERD). Dupilumab, a fully human monoclonal antibody that blocks the shared interleukin (IL)‐4/IL‐13 receptor component, is an approved add‐on treatment in severe CRSwNP. This post hoc analysis evaluated dupilumab efficacy and safety in patients with CRSwNP with/without NSAID‐ERD. Methods Data were pooled from the phase 3 SINUS‐24 and SINUS‐52 studies in adults with uncontrolled severe CRSwNP who received dupilumab 300 mg or placebo every 2 weeks. CRSwNP, nasal airflow, lung function, and asthma control outcomes at Week 24 were evaluated, and treatment–subgroup interactions were assessed for patients with and without NSAID‐ERD. Results Of 724 patients, 204 (28.2%) had a diagnosis of NSAID‐ERD. At Week 24, least squares mean treatment differences demonstrated significant improvements in nasal polyp score, nasal congestion (NC), Lund–Mackay computed tomography, 22‐item Sinonasal Outcome Test (SNOT‐22), Total Symptom Score (TSS), rhinosinusitis severity visual analog scale, peak nasal inspiratory flow (PNIF), six‐item Asthma Control Questionnaire score, and improvement in smell with dupilumab versus placebo (all p
