Mechanism of action

Dupilumab binds to IL-4 receptor alpha, a shared component of IL-4 and IL-13 signaling pathways that drive type 2 inflammation. By blocking this receptor, it suppresses the production of IgE and inflammatory cytokines, reducing eosinophil recruitment and activation. This mechanism addresses the underlying pathophysiology of multiple type 2 inflammatory conditions including atopic dermatitis, asthma, and eosinophilic diseases.
