drug_description
Afucosylated humanized IgG1 monoclonal antibody targeting the IL-5 receptor alpha (IL-5Rα) on eosinophils and basophils, inducing antibody-dependent cell-mediated cytotoxicity (ADCC) and resulting in near-complete eosinophil depletion.

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.

drug_mechanism_of_action
Afucosylated humanized IgG1 monoclonal antibody targeting IL-5 receptor alpha on eosinophils and basophils; enhanced FcγRIIIa engagement drives potent ADCC, leading to near-complete depletion of eosinophils (and basophils) and functional blockade of IL-5 signaling, thereby reducing eosinophilic inflammation.
