A total of 917 adult patients in Trials 1 and 2 (16‑week trials) and 421 adult patients in Trial 3 (52‑week trial) with moderate‑to‑severe atopic dermatitis not adequately controlled with topical prescription treatments were randomized to DUPIXENT 300 mg Q2W or placebo. For all patients in Trial 3, lesions were treated with concomitant TCS.1
Disease severity was defined by an IGA score ≥3 in the overall assessment of atopic dermatitis lesions on a severity scale of 0 to 4, an EASI score ≥16 on a scale of 0 to 72, and a minimum body surface area involvement of ≥10%.1,a
Primary endpoint across all 3 adult pivotal trials: Change from baseline to Week 16 in the proportion of subjects with an IGA 0 (clear) or 1 (almost clear) and a ≥2-point improvement1

Adult clinical trials included monotherapy (Trials 1 and 2) and with concomitant TCS (Trial 3); all trials initiated with two 300 mg DUPIXENT or placebo subcutaneous injections at Week 0, and emollient background regimen was required.1
Treatment effects in subgroups in Trials 1, 2, and 3 were generally consistent with the results in the overall adult study population1,f
