Introduction: Clinical trials demonstrated that upadacitinib is efficacious in treating atopic dermatitis (AD). Its real-world effectiveness is less understood. In this study, we investigated the longitudinal real-world outcomes of upadacitinib-treated adults in the CorEvitas AD Registry. Methods: The CorEvitas AD Registry is a prospective, non-interventional registry of adults diagnosed with AD in the United States and Canada. We evaluated participants enrolled through April 30, 2024 with data available prior to upadacitinib exposure (baseline) and at the six-month follow-up visit, and were receiving upadacitinib at the follow-up visit. Outcomes evaluated include the achievement of: Validated Investigators Global Assessment Scale for Atopic Dermatitis (vIGA-ADTM) of “clear” or “almost clear” among participants rated “mild” or worse at baseline (vIGA-AD 0/1); Eczema Area and Severity Index improvement of ≥75%/≥90%/100% from baseline (EASI 75/90/100); Peak Pruritus Numeric Rating Scale (PP-NRS) improvement ≥4 among participants with a score ≥4 at baseline (∆PP-NRS≥4); PP-NRS score of 0 or 1 among participants with a score >1 at baseline (PP-NRS 0/1); Dermatology Life Quality Index (DLQI) score improvement ≥4 among participants with a score ≥4 at baseline (∆DLQI≥4); and DLQI score of 0 or 1 among participants with a score >1 at baseline (DLQI 0/1). Simultaneous achievement of both EASI 90 & PP-NRS 0/1 was also assessed. Data were analyzed as observed with no imputation. Safety events were not assessed in this analysis. Results: The longitudinal analysis included 192 participants (mean age 46.2 years; 57.8% female; 69.8% White; 43.8% prior exposure to dupilumab or tralokinumab; 64.4% receiving 15 mg dose at follow-up visit; mean upadacitinib treatment duration of 6.0 months). More than half achieved clear/almost clear skin (66.1% vIGA-AD 0/1), EASI 75 (69.3%), and EASI 90 (59.2%); 45.3% achieved complete skin clearance (EASI 100). More than 40% reported little-to-no itch (44.4% PP-NRS 0/1) and no impact of AD on quality of life (43.3% DLQI 0/1), and more than half reported meaningful improvements in itch (58.6% ∆PP-NRS≥4) and quality of life (76.0% ∆DLQI≥4). Simultaneous attainment of both EASI 90 & PP-NRS 0/1 was achieved in 46.6% of participants at 6 months. Conclusions: In the real-world setting, the majority of adults treated and remained on upadacitinib achieved clinically meaningful outcomes in skin lesions, itch, and quality of life, with many achieving complete skin clearance, little-to-no itch, and experiencing no impact of AD on their quality of life. These findings underscore upadacitinib's potential to offer multidimensional relief to patients with AD in everyday clinical practice.
