Key clinical point: Dupilumab showed an acceptable safety profile and sustained efficacy through 52 weeks in adolescents with inadequately controlled moderate-to-severe atopic dermatitis (AD).
Major finding: Rate of treatment emergent adverse events was 370.2 events/100 patient-years, with most being mild/moderate. At least 75% improvement in Eczema Area and Severity Index scores was achieved by 81.2% of patients receiving dupilumab at week 52 and 51.9% of patients who were uptitrated from every-4-week (q4w) to every-2-week (q2w) dosing regimen at week 48 after the first uptitration visit.
Study details: Findings are from an ongoing open-label extension study, LIBERTY AD PED-OLE , including 294 adolescents with moderate-to-severe AD who participated in previous dupilumab trials, received dupilumab q4w, and were uptitrated to the weight-tiered q2w dose regimen upon inadequate clinical response.
Disclosures: This study was funded by Sanofi and Regeneron Pharmaceuticals, Inc. Eight authors declared being employees or shareholders of Regeneron Pharmaceuticals or Sanofi, and the other authors reported ties with various sources, including Sanofi and Regeneron.
