Dupilumab shows rapid and sustained efficacy and favorable safety in erythrodermic atopic dermatitis

Key clinical point: Dupilumab with or without concomitant topical corticosteroids (TCS) was safe and provided rapid and sustained improvements in atopic dermatitis (AD) signs and symptoms in patients with erythrodermic AD.

Major finding: At week 16, dupilumab without and with concomitant TCS vs placebo provided significant improvements in the percentage of AD-affected body surface area (P = .02 and P < .001, respectively), Eczema Area and Severity Index score (P = .002 and P < .001, respectively), and Peak Pruritus Numerical Rating Scale score (P < .001 and P = .002, respectively), with improvements observed from week 1. Most treatment-emergent adverse events were mild or moderate in severity.

Study details: This post hoc analysis of six multicenter randomized trials included 209 patients with erythrodermic AD who were randomly assigned to receive dupilumab or placebo (both with or without concomitant TCS).
