Mechanism of action

Benralizumab targets interleukin-5 receptor alpha (IL-5Rα), a key receptor expressed on eosinophils and basophils. By blocking this receptor, the drug prevents IL-5 signaling and promotes antibody-dependent cellular cytotoxicity (ADCC), resulting in rapid depletion of these cells. This mechanism effectively reduces eosinophilic inflammation in conditions like severe eosinophilic asthma.
