Key clinical point: Both oral and topical Janus kinase inhibitors (JAKi) led to clinically meaningful improvement in the severity of atopic dermatitis (AD), with topical JAKi demonstrating an excellent safety profile and oral JAKi demonstrating an adverse effect (AE) profile that warrants monitoring.
Major finding: Patients receiving JAKi vs. placebo showed a significant improvement in the Eczema Area and Severity Index score (standardized mean difference [SMD] −0.79) and the pruritus numerical rating scale score (SMD −0.49; both P < .00001). Although patients in topical JAKi groups experienced no significant AE; however, those in oral JAKi groups were at an increased risk for ≥1 AE (odds ratio 1.23; P < .0001) with the most frequent AE being gastrointestinal disorders ( P < .00001) and headache ( P = .0003).
Study details: Findings are from a meta-analysis of 25 studies including 9931 patients with AD, of which 2383 and 7548 participants were involved in topical and oral JAKi studies, respectively.
Disclosures: This study did not receive any funding. No conflicts of interest were reported.
