Key clinical point: Dupilumab showed an acceptable safety profile and sustained efficacy through 4 years in adults with moderate-to-severe atopic dermatitis (AD).
Major finding: At 4 years, the exposure-adjusted incidence rate of treatment emergent adverse events (TEAE) was 256.86 events/100 patient-years, with most events being mild to moderate in severity. At least one serious and severe TEAE was experienced by 10.4% and 9.8% of patients in two dose categories. At week 204, the mean Eczema Area and Severity Index (EASI) score improved by 91.07%, with patients switching from 300 mg dupilumab weekly to every-2-weeks dosing while maintaining EASI scores up to 48 weeks post-transition.
Study details: Findings are from an interim analysis of the ongoing phase 3, LIBERTY AD open-label extension study including 2677 adults with moderate-to-severe AD who received 300 mg dupilumab weekly or every 2 weeks in previous phase 1-3 AD trials.
Disclosures: This study was funded by Sanofi and Regeneron Pharmaceuticals, Inc. Seven authors declared being employees or shareholders of Regeneron Pharmaceuticals or Sanofi, and other authors reported ties with various sources.
