Benralizumab
nci_thesaurus_definition
An afucosylated, humanized monoclonal antibody against the alpha chain of the interleukin-5 receptor (IL-5Ra), with potential anti-asthmatic activity. Upon administration, benralizumab binds to IL-5Ra and elicits an antibody-directed cell cytotoxicity (ADCC) against IL-5Ra-expressing cells. This induces apoptosis in IL-5Ra-expressing cells and may reduce asthmatic episodes. IL-5Ra, expressed on both eosinophils and basophils, plays a key role in asthma.

Afucosylated humanized IgG1 monoclonal antibody targeting IL-5 receptor alpha that blocks IL-5 signaling and engages FcγRIIIa to drive potent ADCC, depleting IL-5Rα–expressing eosinophils and basophils to reduce eosinophilic inflammation.
