Atopische Dermatitis: Kombination aus Dupilumab und Kortikosteroid auch bei 6- bis 11-Jährigen erfolgreich

Abstract

Background: Children with severe atopic dermatitis (AD) have limited treatment options. Objective: We report the efficacy and safety of dupilumab + topical corticosteroids (TCS) in children aged 6–11 years with severe AD inadequately controlled with topical therapies. Methods: In this double-blind, 16-week, phase 3 trial (NCT03345914), 367 patients were randomized 1:1:1 to 300 mg dupilumab every 4 weeks (300 mg q4w), a weight-based regimen of dupilumab every 2 weeks (100 mg q2w, baseline weight <30 kg; 200 mg q2w, baseline weight ≥30 kg), or placebo; with concomitant medium-potency TCS. Results: Both the q4w and q2w dupilumab + TCS regimens resulted in clinically meaningful and statistically significant improvement in signs, symptoms, and quality of life (QOL) versus placebo + TCS in all prespecified endpoints. For q4w, q2w, and placebo, 32.8%, 29.5%, and 11.4% of patients, respectively, achieved Investigator’s Global Assessment scores of 0 or 1; 69.7%, 67.2%, and 26.8% achieved ≥75% improvement in Eczema Area and Severity Index scores; and 50.8%, 58.3%, and 12.3% achieved ≥4-point reduction in worst itch score. Response to therapy was weight-dependent: optimal dupilumab doses for efficacy and safety were 300 mg q4w in children <30 kg and 200 mg q2w in children ≥30 kg. Conjunctivitis and injection-site reactions were more common with dupilumab + TCS than with placebo + TCS. Limitations: Short-term 16-week treatment period; severe AD only. Conclusion: Dupilumab + TCS is efficacious and well tolerated in children with severe AD, significantly improving signs, symptoms, and QOL.
