Successful tapering of dupilumab in patients with atopic dermatitis with low disease activity: a large pragmatic daily practice study from the BioDay registry

BACKGROUND: Limited data are available regarding patient-centred dosing of dupilumab for atopic dermatitis (AD) in daily practice. OBJECTIVES: To evaluate our patient-centred dupilumab dosing regimen in daily practice, to assess prognostic factors for successful tapering and to estimate medication-related cost savings. METHODS: This prospective multicentre study included adult patients with AD, participating in the BioDay registry, treated with dupilumab for ≥ 1.3 years. Interval prolongation was considered in the case of dupilumab standard dose for ≥ 1 year and persistent controlled AD [Eczema Area and Severity Index (EASI) ≤ 7; ≥ 6 months]. Primary endpoints were the mean EASI and Numeric Rating Scale (NRS)-pruritus after the start of tapering. Prognostic factors for successful tapering were analysed with logistic regression and a cost-savings analysis was performed. RESULTS: A total of 595 patients were included, of whom 401 patients [mean EASI 2.5 (SD 2.3); NRS-pruritus of 2.4 (SD 1.9) at the start of tapering] prolonged their dupilumab interval. In 83.3% of these patients tapering was successful; most patients used dupilumab every 3 or 4 weeks (Q3W/Q4W). A significant small increase was observed for EASI (highest mean 3.5) and NRS-pruritus (highest mean 3.2) (P < 0.001); however, scores remained low. Predicting successful tapering showed nonsignificant odds ratios for all incorporated variables. The estimated cost savings was €3 977 033.98 for 401 patients between January 2019 and June 2022. CONCLUSIONS: This study showed successful tapering of dupilumab in 83.3% of patients with AD who attempted tapering, while maintaining controlled disease and with the majority using Q3W/Q4W. Interval prolongation can be beneficial both for the patient and from a socio-economic perspective

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 and 8.7, 3.5 and 4.2, and 2.9 and 3.1 in adults, respectively, whilst these patient-reported outcome measures (PROMs) ranged between 8.9 and 10.9, 4.4 and 6.4, and 3.0 and 3.7 in pediatric patients, respectively. At follow-up, overall work impairment decreased from 40.1% to 16.3% to 13.3% 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
