Abstract

BACKGROUND: The decision to initiate advanced systemics in patients with atopic dermatitis (AD) is complex. OBJECTIVES: To explore disease burden and clinical characteristics of patients with moderate-to-severe AD and identify characteristics associated with initiating new systemics. METHODS: Data from prospective, longitudinal, non-interventional CorEvitas AD Registry were evaluated. Differences in demographic and clinical characteristics, comorbidities, disease severity (vIGA-AD; body surface area (BSA); Eczema Area and Severity Index (EASI); SCORing AD [SCORAD]), and patient-reported outcomes (PROs) were assessed between systemic and non-systemic therapy groups. RESULTS: Of 883 patients, 673 were newly prescribed systemics and 210 were not. Non-systemic therapy group had higher than expected rates of severe disease at enrollment based on vIGA-AD = 4 (39%), mean BSA involvement (31%), and mean EASI (19). PROs for non-systemic therapy group indicated elevated burden from AD on quality of life and poor disease control. SCORAD, peak pruritus in the past 24 h, history of biologics, and facial pallor, were significantly associated with initiation of systemics at enrollment. CONCLUSION: While disease burden likely influences the initiation of systemic therapy, many patients with significant burden are not treated with systemics for unclear reasons. Further research is needed to identify other factors, beyond disease severity, that influence this decision.
