Introduction:
Dupilumab was initially approved in 2017 as the first biologic therapy for atopic dermatitis (AD). We characterized adults with AD initiating dupilumab in a real-world setting in the USA/Canada.
Methods:
PROSE is an ongoing, longitudinal, prospective, observational, multicenter registry of patients with AD initiating dupilumab per country-specific prescribing information. We report baseline data (day of first dupilumab injection) for patients enrolled from April 2018 through July 2019.
Results:
Among 315 patients (mean age 42.5 years, 55.2% female), the median AD duration was 17.0 years; 65.4% reported a history of type 2 inflammatory comorbidities (e.g., allergic rhinitis, asthma), and 93.3% reported treatment(s) for AD in the previous year, including topical corticosteroids (90.8%), systemic corticosteroids (36.2%), and nonsteroidal systemic therapies (14.0%). In total, 89.2% had an Overall Disease Severity score of 3 (moderate) or 4 (severe). Other mean disease severity scores included the following: Eczema Area and Severity Index 16.9 (range 0-72), body surface area affected 26.8%, Patient-Oriented Eczema Measure 18.5 (range 0-28), Dermatology Life Quality Index 12.7 (range 0-30), and pruritus Numerical Rating Scale score 6.9 (range 0-10).
Conclusion:
Patients initiating dupilumab have longstanding moderate-to-severe AD with significant disease burden and frequent type 2 comorbidities.
