Short-term Tezepelumab effectiveness in patients with severe asthma: a multicenter study.

AbstractObjectiveMethodsResultsConclusionSevere asthma presents significant management challenges, often requiring advanced treatments to control symptoms and reduce exacerbations. The use of monoclonal antibodies has revolutionized the clinical course of patients with severe asthma, showing a significant impact on exacerbations reduction, oral corticosteroids (OCS) cessation and on the improvement of lung function and quality of life. Tezepelumab, an anti-thymic stromal lymphopoietin (TSLP) monoclonal antibody, has emerged as a potential therapeutic option for these patients.We conducted an observational, prospective, multicenter study including 20 patients with confirmed severe asthma according to ERS guidelines and GINA recommendations. Patients received Tezepelumab 210 mg every 4 wk due to uncontrolled asthma despite maximal inhalation treatment with ICS/LABA. Data were collected before treatment initiation (T0) and after three months from the first administration (T3).After three months of Tezepelumab treatment, we reported significant improvements in asthma symptoms and quality of life, as well as a consistent reduction in exacerbations and OCS use. We found no statistically meaningful differences among main clinical and functional outcomes according to inflammatory biomarkers, while lung function improved significantly in patients with less allergic sensitization. No serious adverse event was reported during the follow up, while the rates of mild adverse effects were comparable to those from registration trials.Tezepelumab demonstrated short-term efficacy in improving asthma control and quality of life, showing a favorable safety profile. Further studies with larger sample sizes and longer follow-up would confirm these findings and identify predictors of response to Tezepelumab. [ABSTRACT FROM AUTHOR]
