33006 Long-term improvement of patient-reported outcomes in adult patients with atopic dermatitis treated with baricitinib in the US and Canada

Abstract

Objective: To evaluate long-term patient-reported outcome (PRO) improvements in patients with atopic dermatitis (AD) treated with baricitinib, a Janus kinase (JAK)1/JAK2 inhibitor. Methods: Data were derived from 2 phase 3 studies: double-blind placebo-controlled BREEZE-AD5 (NCT03435081) and long-term open-label extension BREEZE-AD6 (NCT03559270) through 52 weeks of treatment. Low-potency topical corticosteroids were permitted after Week 16 in BREEZE-AD5 and throughout BREEZE-AD6. PROs [Dermatology Life Quality Index (DLQI), Patient-Oriented Eczema Measure (POEM), and Hospital Anxiety Depression Scale (HADS-anxiety and HADS-depression)] were assessed to Week 52 using descriptive statistics with missing data imputed by last observation carried forward. Results: In 146 patients receiving baricitinib 2 mg, the quality of life measure DLQI (mean ± standard deviation at baseline 15.0 ± 7.6) showed a mean change from baseline of −7.0 ± 8.2 at Weeks 48-52. Patient-reported improvements in skin symptoms as measured by POEM were −7.3 ± 8.8 at Weeks 48-52 from mean baseline value of 21.7 ± 5.4. By Weeks 48-52, 68.9% and 57.6% of patients had achieved a clinically meaningful ≥4-point improvement in DLQI and POEM, respectively. HADS-anxiety and HADS-depression scores were 7.0 ± 4.4 and 5.2 ± 4.3 at baseline, respectively, with patients reporting a change from baseline of −1.9 ± 3.7 and −1.8 ± 3.3 at Weeks 48-52. Conclusion: Patients with moderate to severe AD treated with baricitinib 2 mg experienced clinically meaningful PRO improvements in skin symptoms, quality of life, and anxiety and depression over 52 weeks.
