Randomized Controlled Trial Multicenter Study
Benralizumab for chronic obstructive pulmonary disease and sputum eosinophilia: a randomised, double-blind, placebo-controlled, phase 2a study.
Chronic obstructive pulmonary disease (COPD) is associated with eosinophilic airway inflammation in 10-20% of patients. Benralizumab, an anti-interleukin-5 receptor α monoclonal antibody, depletes blood and sputum eosinophils. We aimed to establish whether benralizumab reduces acute exacerbations of COPD in patients with eosinophilia and COPD. ⋯ MedImmune.

Randomized Controlled Trial Multicenter Study
Benralizumab, an anti-interleukin 5 receptor α monoclonal antibody, versus placebo for uncontrolled eosinophilic asthma: a phase 2b randomised dose-ranging study.
Persistent eosinophilic airway inflammation in asthma increases the risk of exacerbations. In a phase 2b dose-ranging study, we aimed to assess the efficacy and safety of benralizumab, an anti-interleukin 5 receptor α monoclonal antibody that depletes blood and airway eosinophils, in adults with uncontrolled eosinophilic asthma. ⋯ MedImmune.
