Sanofi SNY and Regeneron Pharmaceuticals REGN today announced that pooled data from two Phase 1b trials with dupilumab (REGN668/SAR231893), an investigational, high-affinity, subcutaneously administered, fully-human antibody targeting the alpha subunit of the interleukin 4 receptor (IL-4R alpha), were presented at the 71st Annual Meeting of the American Academy of Dermatology (AAD) in Miami.
