Benralizumab, sold under the brand name Fasenra, is a monoclonal antibody directed against the alpha chain of the interleukin-5 receptor (CD125). It was developed by MedImmune for the treatment of asthma.[3][4]

Two phase III clinical trials of benralizumab reported meeting their primary endpoints in 2016.[5][6] It was approved by the US Food and Drug Administration in November 2017 for the treatment of severe eosinophilic asthma.[7] It was granted designation as an orphan drug by the Food and Drug Administration for treatment of eosinophilic oesophagitis in August 2019.[8]

Common adverse effects include injection site reactions, which were reported in 2.2% of patients (vs. 1.9% for placebo) in clinical trials.[9]
