Efficacy of tezepelumab against uncontrolled severe non‐type 2 asthma refractory to bronchial thermoplasty, benralizumab, dupilumab and mepolizumab

Abstract

Abstract Severe asthma affects approximately 5%–10% of patients with asthma. Herein, we describe a case of non‐type 2 asthma that progressively worsened over the years. An 80‐year‐old woman was diagnosed with asthma 11 years back. She experienced repeated exacerbations requiring treatment with systemic corticosteroid despite therapy with medications including high‐dose inhaled corticosteroids/long‐acting beta‐agonists plus long‐acting muscarinic antagonist. The patient presented with non‐eosinophilic asthma. Therefore, the patient was initially treated with bronchial thermoplasty, which was effective for 1 year only. Treatment with bronchial thermoplasty, benralizumab, dupilumab, and mepolizumab was ineffective. The fourth treatment, which included tezepelumab, was initiated. The patient's symptoms and quality of life improved significantly. This is the first case of a patient who did not respond to sequential bronchial thermoplasty, benralizumab, dupilumab, and mepolizumab but who presented with good clinical response to tezepelumab. Therefore, tezepelumab may be useful for patients with non‐type 2 asthma.
