Sanofi, Regeneron say latest Dupixent eczema drug tests positive

Drugmakers Sanofi and Regeneron said results from a one-year test of their Dupixent product aimed at adults with eczema or moderate-to-severe atopic dermatitis (AD) had been positive.

"In the CHRONOS study, Dupixent used with topical corticosteroids showed significantly greater clearance of skin lesions and overall disease severity compared to topical corticosteroids alone, which are commonly prescribed for moderate-to-severe atopic dermatitis," Andrew Blauvelt, the principal investigator of the study, said in a joint statement from the companies.

"This study provides positive long-term data for Dupixent, which is important given atopic dermatitis is a chronic inflammatory disease," he said.

A biologics license application (BLA) for Dupixent was accepted for Priority Review by the U.S. Food and Drug Administration (FDA) in September 2016.
