Abstract

BACKGROUND: The BURAN study (ClinicalTrials.gov: NCT05552508) was a multicenter open-label study evaluating airway structure/function changes in adults with severe eosinophilic asthma (SEA) following eosinophil depletion by benralizumab. We assessed the changes in airway structure/function following treatment with benralizumab in adults with SEA. METHODS: We recruited adults (18-70 years) with SE…
