Dupilumab is a monoclonal antibody designed for the treatment of atopic diseases.[1] It binds to the alpha subunit of the interleukin-4 receptor (IL-4Rα).[2] Through blockade of IL-4Rα, dupilumab modulates signaling of both the IL-4 and IL-13 pathway, which have been implicated in the pathophysiology of allergic disease.[3]

This drug was developed by Regeneron Pharmaceuticals.

On May 21/2013 mid-stage data was presented at the American Thoracic Society meeting and published in the NEJM demonstrating an 87% reduction in asthma exacerbations in patients with moderate-to-severe allergic asthma.[2]
