Study to Evaluate Efficacy and Safety of Benralizumab in Reducing Oral Corticosteroid Use in Adult Patients With Severe Asthma

This is an open-label, multicenter study designed to evaluate efficacy and safety of reducing daily oral corticosteroid (OCS) use after initiation of 30 mg dose of benralizumab administered subcutaneously (SC) in patients with severe eosinophilic asthma receiving high-dose inhaled corticosteroid (ICS)/long-acting β2 agonist (LABA) and OCS with or without additional asthma controller(s).
