Dupilumab is a monoclonal antibody designed for the treatment of atopic diseases.[1] This drug was developed by Regeneron Pharmaceuticals. The US Food and Drug Administration has designated dupilumab a “breakthrough therapy” which is designed to speed promising new drugs to market.[2]

Mechanism of action

It binds to the alpha subunit of the interleukin-4 receptor (IL-4Rα).[3] Through blockade of IL-4Rα, dupilumab modulates signaling of both the interleukin 4 and interleukin 13 pathway.

Medical uses

The interleukin 4 and 13 pathways have been implicated in the pathophysiology of allergic disease, particularly asthma and atopic dermatitis.[4][5]

Clinical trials

In 2013 mid-stage data was presented at the American Thoracic Society meeting and published in the NEJM demonstrating an 87% (placebo: 67%) reduction in asthma exacerbations in patients with moderate-to-severe allergic asthma.[3] In an atopic dermatitis study, 85% of patients improved their symptoms by at least 50% within twelve weeks (measured by eczema area and severity index), versus 35% in the placebo group.[6]

In 2016 good results were announced from the SOLO1 and SOLO2 phase III trials (for atopic dermatitis/eczema symptoms)[7] and the US FDA granted it priority review status with a final decision due by March 2017.[8]
