Yes. DUPIXENT treatment decreased FeNO (up to 35% reduction from baseline by Week 2^a) and circulating concentrations of eotaxin-3, total IgE (up to 83% reduction from baseline at Week 96^b), allergen-specific IgE, TARC, and periostin in asthma subjects relative to placebo. DUPIXENT decreased these markers of type 2 inflammation and sustained the effects throughout treatment. In addition, there was an impact on eosinophil activation and trafficking (up to 35% median reduction from baseline at Week 96^b). The mechanism of dupilumab action has not been definitively established.^1,6-12
