Abstract
Background: Chronic rhinosinusitis with nasal polyps is a predominantly type-2 mediated inflammatory disease with high symptom and quality of life burden. Dupilumab significantly improved 22-item Sino-Nasal Outcome Test (SNOT-22) total score vs placebo (PBO) in SINUS-24 and SINUS-52 trials (NCT02912468; NCT02898454).
Objectives: Post hoc analysis of pooled SINUS-24 and SINUS-52 to identify the SNOT-22 items most important to patients (pts), assess the effect of dupilumab on these items, and association with objective disease measures.
Methods: Nasal polyp (NPS) and Lund-Mackay (LMK) scores were assessed in pts with and without improvement at Wk 24 in the SNOT-22 items ranked most important by pts at baseline (BL).
Results: Decreased sense of smell/taste and nasal blockage were the most important SNOT-22 items at BL (cited important by 87% and 82% of pts, respectively). More dupilumab (N=438) vs PBO (N=286) pts improved in these items at Wk 24 (smell/taste: 76.7% vs 30.4%; nasal blockage: 79.5% vs 44.4%). Dupilumab significantly improved NPS and LMK in all pts regardless of improvement in SNOT-22 items, with the greatest treatment effect seen in pts who had an improvement (Table below).
Conclusions: A higher percentage of dupilumab-treated pts improved in symptoms most important to pts (smell/taste; nasal blockage) vs PBO. Improvement in these symptoms signals greater improvement in objective measures (LMK and NPS).
