FDA accepts BLA for dupilumab to treat moderate-to-severe atopic dermatitis.- Sanofi + Regeneron

Sanofi and Regeneron Pharmaceuticals, Inc. announced that the FDA has accepted for priority review the Biologics License Application (BLA) for dupilumab for the treatment of adult patients with inadequately controlled moderate-to-severe atopic dermatitis (AD), a serious, chronic inflammatory skin disease. The application has been given a Prescription Drug User Fee Act (PDUFA) target action date of March 29, 2017. The investigational biologic therapy dupilumab 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 major driver in the pathogenesis of the disease.

The BLA for dupilumab contains data from three Phase III pivotal studies in the global LIBERTY AD program that included more than 2,500 patients. The goal of the studies was to evaluate dupilumab 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. In 2014, the FDA granted Breakthrough Therapy designation to dupilumab for the treatment of adults with moderate-to-severe AD who are not adequately controlled with topical prescription therapies or for whom these treatments are not appropriate.
