Effect of Tezepelumab on Sino-Nasal Outcome Test (SNOT)-22 Domain and Symptom-Specific Scores in Patients with Severe, Uncontrolled Asthma and a History of Chronic Rhinosinusitis with Nasal Polyps

AbstractIntroductionTezepelumab blocks the activity of thymic stromal lymphopoietin, an epithelial cytokine implicated in the pathogenesis of asthma and chronic rhinosinusitis with nasal polyps (CRSwNP). In a previous analysis, tezepelumab improved asthma and rhinosinusitis symptoms compared with placebo in patients with severe, uncontrolled asthma and a history of CRSwNP in the 2years before randomization in the NAVIGATOR study. This post hoc analysis of patients with a CRSwNP diagnosis at any time before randomization in NAVIGATOR enabled domain and symptom-specific analyses of Sino-Nasal Outcome Test (SNOT)-22 outcomes.MethodsPatients (aged 12–80years) with severe, uncontrolled asthma were randomized to tezepelumab 210mg or placebo subcutaneously every 4weeks for 52weeks. SNOT-22 total, domain, and item scores were assessed in patients with a history of CRSwNP. Annualized asthma exacerbation rate (primary efficacy outcome), pre-bronchodilator forced expiratory volume in 1s, and Asth...
