Tezepelumab on Airway Structure and Function in Patients With Uncontrolled Moderate-to-severe Asthma

Summary

In adult patients with uncontrolled moderate-to-severe asthma, blocking TSLP with tezepelumab will improve ventilation heterogeneity (evaluated by hyperpolarized 129Xe MRI), and this will be associated with reduced airway inflammation (evaluated by sputum composition), luminal narrowing and plugging (evaluated by CT).
