Key clinical point: Some patients with atopic dermatitis (AD) who failed to achieve ≥75% improvement in Eczema Area and Severity Index (EASI)-75 and Investigator’s Global Assessment score of 0/1 (IGA 0/1) after initial 16-week treatment with dupilumab seemed to benefit from continued long-term treatment.
Major finding: Among patients with a suboptimal 16-week response to dupilumab, 91% achieved EASI-75 by week 100 with 49% of patients receiving initial dupilumab once weekly and 45% on every 2 weeks achieving IGA 0/1 at week 100.
Study details: Findings are a post hoc analysis of 100-week data from dupilumab open-label extension study including 391 adults with moderate-to-severe AD who received 300 mg dupilumab weekly after showing suboptimal response with weekly or every 2 weeks dosing in the parent study.
