Key clinical point: Baricitinib could serve as an effective treatment option for patients with difficult-to-treat moderate-to-severe atopic dermatitis (AD), including those unresponsive to dupilumab treatment; however, a high discontinuation rate indicates its rather heterogenous efficacy.
Major finding: At week 16, the mean Eczema Area and Severity Index score and numerical rating scale-pruritis significantly decreased from 18.3 to 11.1 (P < .0001) and from 6.6 to 5.3 (P < .0001), respectively. The most frequent adverse events (AE) were nausea (11.8%), urinary tract infection (9.8%), and herpes simplex infections (7.8%). Baricitinib treatment was discontinued by 43.2% of patients due to ineffectiveness or AE.
Study details: This multicenter prospective observational study included 51 adult patients with moderate-to-severe AD from the BioDay registry who received baricitinib over 16 weeks.
Disclosures: This study did not report a source of funding. Some authors declared serving as speakers, consultants, advisory board members, or investigators for various organizations.
