Dupilumab provides sustained effectiveness on patient-reported outcomes and favorable safety in patients with moderate-to-severe atopic dermatitis: Up to 5-year results from the daily practice BioDay registry

Background Long-term daily practice data on patient-reported benefits of dupilumab for atopic dermatitis (AD) remains limited. Objective To evaluate patient-reported outcome measures (PROMs) and the safety of dupilumab in patients with moderate-to-severe AD over a follow-up period of up to 5 years. Methods Data were extracted from the prospective, multicenter BioDay registry (October 2017 - 2022) of patients with moderate-to-severe AD treated with dupilumab in daily practice. Results In total 1223 patients, 1108 adults and 115 pediatric patients, were included. After ≥1 year of treatment, mean Patient-Oriented Eczema Measure (POEM), Dermatology Life Quality Index (DLQI), Numeric rating scale (NRS)-pruritus ranged between 7.8-8.7, 3.5-4.2, and 2.9-3.1 in adults, respectively, whilst these PROMs ranged between 8.9-10.9, 4.4-6.4, and 3.0-3.7 in pediatric patients, respectively. At follow-up, overall work impairment decreased from 40.1% to 13.3-16.3% in adults. Furthermore, class I obesity and itch-dominant patients generally had less favorable treatment response. Of all patients, 66.8% reported ≥1 adverse event, with conjunctivitis being the most common(33.7%). Limitations The overall percentage of missing values for selected PROMs was 26% in adults and 46% in pediatric patients. Conclusion In addition to favorable safety, dupilumab has demonstrated sustained effectiveness across various PROMs, underscoring the treatment benefits from patients' perspectives.
