Mechanism of action

IL-4 and IL-13 are key cytokines driving type 2 inflammatory responses. By binding to IL-4Rα, lebrikizumab prevents both IL-4 and IL-13 from activating their downstream signaling pathways, thereby suppressing eosinophilic and allergic inflammation. This mechanism is particularly relevant in diseases characterized by elevated type 2 immune responses.
