Key clinical point: A longer dupilumab dosing interval might be a good treatment option for patients with atopic dermatitis (AD) who have achieved good clinical response (GCR) or report treatment-related conjunctivitis with a previous dupilumab treatment (600 mg followed by 300 mg every 2 weeks).
Major finding: In the GCR group, the mean Eczema Area and Severity Index (EASI) score was 28.22, which reduced significantly to 0.44 among patients receiving dupilumab once every 3 weeks (Q3W) and to 0.19 among patients receiving dupilumab once every 4 weeks (Q4W) after >60 weeks (both P < .0001). EASI improved after 18 weeks in the treatment-resistant conjunctivitis group (P < .0001).
Study details: Findings are retrospectively collected data of 59 adult patients with AD who implemented Q3W (84.75%) or Q4W (15.25%) dupilumab dosing interval due to GCR or conjunctivitis.
Disclosures: This study did not receive any funding. Some authors declared serving as speakers, investigators, consultants, or advisory board members, or receiving personal fees from several sources.
