Regulatory compliance standardsSanofi and Regeneron Pharmaceuticals, Inc.  have announced that the European Medicines Agency (EMA) has accepted for review the Marketing Authorization Application (MAA) for Dupixent (dupilumab) for the treatment of adults with moderate-to-severe atopic dermatitis (AD) who are candidates for systemic therapy.

The investigational biologic therapy Dupixent inhibits signaling of IL-4 and IL-13, two key cytokines required for the type 2 (including Th2) immune response, which is believed to be a major driver in the pathogenesis of the disease. 

The MAA for Dupixent contains data from three Phase III pivotal studies in the global LIBERTY AD programme that included more than 2500 patients. The objective of the studies was to evaluate Dupixent as monotherapy (SOLO 1 and SOLO 2) and in concomitant administration with topical corticosteroids (CHRONOS), in adult patients with moderate-to-severe AD whose disease is not adequately controlled with topical prescription therapies.  

A biologics license application (BLA) for Dupixent was accepted for Priority Review by the US Food and Drug Administration (FDA) in September 2016. Per the Prescription Drug User Fee Act (PDUFA), the target FDA action date is 29 March 2017. The European Medicines Agency (EMA) and FDA have conditionally accepted Dupixent as the trade name for dupilumab.

Dupixent is currently under clinical development and its safety and efficacy have not been fully evaluated by any regulatory authority. In addition to AD in adults, Dupixent is being studied in pediatric AD, asthma, nasal polyposis and eosinophilic esophagitis. If approved, Dupixent would be commercialized by Regeneron and Sanofi Genzyme, the specialty care global business unit of Sanofi.
