Regeneron Pharmaceuticals, Inc. and Sanofi announced that a one-year phase 3 study, known as LIBERTY AD CHRONOS, evaluating investigational dupilumab met its primary and key secondary endpoints. In the study, dupilumab with topical corticosteroids (TCS) was compared to TCS alone in moderate-to-severe atopic dermatitis (AD) adult patients. Patients in the study were inadequately controlled by topical corticosteroids (TCS) with or without topical calcineurin inhibitors (TCI). Dupilumab with TCS significantly improved measures of overall disease severity at 16 and 52 weeks, when compared to placebo with TCS.
