Tezepelumab in Adults with Severe Chronic Rhinosinusitis with Nasal Polyps

Treatment with tezepelumab has been effective for sinonasal symptoms in patients with severe, uncontrolled asthma and a history of chronic rhinosinusitis with nasal polyps, but its efficacy and safety in adults with severe, uncontrolled chronic rhinosinusitis with nasal polyps is unknown.

We randomly assigned adults with physician-diagnosed, symptomatic, severe chronic rhinosinusitis with nasal polyps to receive standard care and either tezepelumab (at a dose of 210 mg) or placebo subcutaneously every 4 weeks for 52 weeks. The coprimary end points were the changes from baseline in the total nasal-polyp score (range, 0 to 4 [for each nostril]; higher scores indicate greater severity) and the mean nasal-congestion score (range, 0 to 3; higher scores indicate greater severity) at week 52. Key secondary end points assessed in the overall population were the loss-of-smell score, the total score on the Sinonasal Outcome Test (SNOT-22; range, 0 to 110; higher scores indicate greater severity), the Lund-Mackay score (range, 0 to 24; higher scores indicate greater severity), the total symptom score (range, 0 to 24; higher scores indicate greater severity), and the first decision to treat with nasal-polyp surgery or use of systemic glucocorticoid therapy, or both, assessed in time-to-event analyses (individual and composite).
