Dupilumab treatment with concomitant topical corticosteroids provided rapid and sustained improvement in itch intensity and frequency in children aged 6-11 years with severe atopic dermatitis.

The findings come from a post hoc analysis of a phase 3 trial known as LIBERTY AD PEDS (NCT03345914) that Gil Yosipovitch, MD, presented during a late-breaking research session at the Revolutionizing Atopic Dermatitis virtual symposium.
"Severe AD is complex, highly symptomatic, multidimensional condition characterized by an intense pruritus that negatively impacts a patient's life," said Yosipovitch, professor of dermatology and director of the Miami Itch Center at the University of Miami. Published data from the double-blind, placebo-controlled, 16-week, LIBERTY AD PEDS trial in children aged 6–11 years with severe AD showed that dupilumab significantly improved AD signs, symptoms, and quality of life, with an acceptable safety profile (J Am Acad Dermatol. 2020;21:119-31).
For the current analysis, Yosipovitch and colleagues evaluated the time to onset, magnitude, and sustainability of the effect of dupilumab on different measures of itch using data from approved Food and Drug Administration doses studied in the LIBERTY AD PEDS trial. A total of 243 children aged 6-11 years were randomized to dupilumab 300 mg every 4 weeks (300 mg q4w, baseline weight of less than 30 kg; 600-mg loading dose), 200 mg every 2 weeks (200 mg q2w, baseline weight 30 kg or greater; 400-mg loading dose), or placebo.
