Tezspire approved in the US for severe asthma.- AstraZeneca + Amgen.

Tezspire was approved following a Priority Review by the FDA and based on results from the PATHFINDER clinical trial programme. The application included results from the pivotal NAVIGATOR Phase III trial in which Tezspire demonstrated superiority across every primary and key secondary endpoint in patients with severe asthma, compared to placebo, when added to standard therapy.

Tezspire is a first-in-class biologic for severe asthma that acts at the top of the inflammatory cascade by targeting thymic stromal lymphopoietin (TSLP), an epithelial cytokine. It is the first and only biologic to consistently and significantly reduce asthma exacerbations across Phase II and III clinical trials which included a broad population of severe asthma patients irrespective of key biomarkers, including blood eosinophil counts, allergic status and fractional exhaled nitric oxide (FeNO). Tezspire is the only biologic approved for severe asthma with no phenotype (e.g. eosinophilic or allergic) or biomarker limitation within its approved label.

Professor Andrew Menzies-Gow, Director of the Lung Division, Royal Brompton Hospital, London, UK, and principal investigator of the NAVIGATOR trial, said: “Due to the complex and heterogeneous nature of severe asthma and despite recent advances, many patients continue to experience frequent exacerbations, an increased risk of hospitalisation and a significantly reduced quality of life. Tezspire represents a much-needed new treatment for the many patients who remain underserved and continue to struggle with severe, uncontrolled asthma.”
