Common therapeutic uses

Treats severe eosinophilic asthma and other conditions characterized by elevated eosinophil counts driven by IL-5, such as eosinophilic granulomatosis with polyangiitis (EGPA).

As an IL-5 antagonist, it binds to IL-5 with high affinity (Kd=10.5 pM), blocking its interaction with the IL-5 receptor alpha chain and inhibiting eosinophil activation, survival, and inflammatory responses.

Administered as an injectable biologic; requires proper diagnosis of eosinophilic phenotype; monitor for hypersensitivity reactions and parasitic infections.
