Mechanism of action

These monoclonal antibodies bind to the IL-5 receptor (IL-5R) on the surface of eosinophils and their precursors, blocking the signaling pathway that promotes eosinophil survival, activation, and recruitment. By inhibiting IL-5 signaling, these antibodies reduce circulating and tissue eosinophil counts, thereby suppressing eosinophil-mediated inflammatory responses in conditions characterized by eosinophilic inflammation.
