DUPIXENT blocks the signaling of two key sources of Type 2 inflammation (IL-4 and IL-13). This inflammation is an important
component in the development of asthma, eczema, chronic obstructive pulmonary disease, chronic rhinosinusitis with nasal polyps, eosinophilic esophagitis, chronic spontaneous urticaria, and bullous pemphigoid.
