Dupilumab Dose Reduction Achievable in Persistently Controlled Atopic Dermatitis

Key clinical point: Dose reduction of 300 mg dupilumab was successfully achieved by dose spacing to >2 weeks without loss of efficacy in most patients with persistently controlled atopic dermatitis (AD), regardless of previous exposure to biologics and Janus kinase inhibitors (JAKi).

Major finding: At a median follow-up of 10 months, dose spacing of 300 mg dupilumab without loss in efficacy was achieved in 35 of 37 patients with controlled AD receiving dupilumab treatment for a median duration of 20.1 months. Similar findings were observed in patients with vs without previous exposure to biologics or JAKi (P > .05).

Study details: Findings are from a retrospective cohort study including 37 patients with controlled AD for more than a year, who were treated with 300 mg dupilumab at intervals > 2 weeks, and of whom 7 patients were classified as non-naive to biologics and JAKi.
