16-week, randomised, double-blind, placebo-controlled, multi-centre, parallel-group, Phase 3 trial including adolescent patients who had moderate-to-severe AD, and were not adequately controlled by topical treatment

|AD-1526||16||251*||Patients were randomised (1:1:1) to 16 weeks of treatment with
a) 200 mg (weight, <60 kg) or 300 mg (weight, ≥60 kg) DUPIXENT Q2W (n=82) (licensed dose)†,
b) 300 mg DUPIXENT Q4W (n=84) or c) placebo Q2W (n=85).
One patient in the DUPIXENT Q4W group was randomised but did not receive treatment.
|The proportion of patients with both IGA 0/1 (clear/almost clear) and the proportion of patients achieving 75% improvement in EASI (EASI-75) from baseline to Week 16.|
*Patients were 12 to 17 years old with moderate-to-severe AD inadequately controlled by topical therapies. Inclusion criteria was defined by IGA score ≥3, and EASI score ≥16, pruritus NRS ≥4, and a minimum BSA involvement of ≥10.
†Topical therapy and other systemic atopic dermatitis therapies were prohibited but allowed as rescue treatment for intolerable symptoms. The use of rescue treatment resulted in patient being classed as a non-responder.
