PARIS-- French drug giant Sanofi (SAN.FR) and U.S. partner Regeneron Pharmaceuticals (REGN) said a one-year phase three trial study showed a treatment combining their drug dupilumab with topical corticosteroids significantly improved the situations of a group of patients suffering from atopic dermatitis.

The treatment including dupilumab improved the overall severity of the disease for patients whose atopic dermatitis was inadequately controlled by a treatment of just topical corticosteroids, the companies said Monday.

The patients who took the dupilumab treatment were compared with another group of similar patients who took topical corticosteroids and a placebo.

Large pharmaceutical labs like Sanofi are rushing to develop new drugs to replace a number of existing drugs that are entering the public domain, which would allow generic pharmaceutical groups to produce and sell the same drugs at a fraction of the current price, a phenomenon known as the "patent cliff."
