Mechanism of action

AK001 binds to Siglec-8, an inhibitory receptor expressed on eosinophils and mast cells, and uses its bispecific design to induce cell death of these effector cells involved in allergic and eosinophilic diseases. By depleting eosinophils and mast cells, the drug reduces the inflammatory cascade characteristic of type 2 immune responses, potentially providing therapeutic benefit in eosinophil-driven and mast cell-driven conditions.
