251 adolescent patients
(12-17 years) studied in AD‑15261

Clinical trials in adolescents included 1 monotherapy trial (AD‑1526) and 1 open-label extension trial (AD‑1434). In AD‑1526, patients were initiated with 2 DUPIXENT (200 mg or 300 mg) doses or placebo (subcutaneous injection) at Week 0 followed by 1 DUPIXENT (200 mg or 300 mg) dose or placebo every 2 weeks, based on the adolescent’s weight.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

dWeekly averaged Peak Pruritus NRS score (10 indicates the most severe).1

Primary endpoint in the adolescent clinical trial: The proportion of subjects with an IGA 0 (clear) or 1 (almost clear) and a ≥2-point improvement at Week 16.1

Other endpoints included the proportion of subjects with EASI-75 at Week 16 and ≥4-point improvement in the Peak Pruritus NRS at Week 16.1
