These therapies are generally indicated for patients with eosinophilic or allergic asthma phenotypes; to date, there are no approved biologic treatments for patients with confirmed eosinophil-low asthma (in the absence of eosinophil-lowering systemic corticosteroid therapy). Studies in progress will provide further evidence of whether tezepelumab can be an effective treatment for a broad population of patients with severe asthma. Worsening of asthma was defined as new or increased symptoms or signs that were either worrisome to the patient or related to an asthma diarydriven alert. Overexpression of TSLP can result in pathologic inflammation that can lead to asthma exacerbations, symptoms, and physiological effects such as bronchoconstriction and airway hyperresponsiveness and remodelling. 2018;209(S2):S2833. tezspire (tezepelumab) is being developed by astrazeneca in collaboration with amgen as a potential first-in-class human monoclonal antibody that inhibits the action of tslp, a key epithelial cytokine that sits at the top of multiple inflammatory cascades and is critical in the initiation and persistence of allergic, eosinophilic and other types [, Chen H, Gould MK, Blanc PD, Miller DP, Kamath TV, Lee JH, et al.
