The efficacy and safety of dupilumab for the treatment of atopic dermatitis among Chinese patients in clinical practice: A single‐center retrospective study

Little real-work data regarding the efficacy and safety of dupilumab in the treatment of atopic dermatitis (AD) is available at present. To assess the efficacy and safety of dupilumab at 12 weeks in the treatment of AD in clinical routine clinical practice. A retrospective, single-centre study of adult patients with moderate to severe AD treated with dupilumab for 12 weeks in China. In total, 60 patients (48 male, 12 female; mean age: 53.2 ± 15.6) were enrolled in this retrospective study. These patients exhibited a mean AD disease course of 10.6 years (6.0), 30% exhibited a family history of allergies, and 31 (51.7%) had one or more allergic comorbidities. Following dupilumab treatment for 12 weeks, 83.3% and 42% of patients had achieved EASI-50 and EASI-75, respectively. Overall, adverse events (AEs) were reported by 15% of patients, with the most common being conjunctivitis, injection site reactions, and herpes simplex virus infections. Laboratory testing after 12 weeks revealed pronounced decreases in both circulating eosinophil counts (from 0.6 (0.1-2.8) to 0.3 (0.1-9.7) 109 /L) and total IgE concentrations (from 327 (2.46-2500) to 230 (47.6-2200) U/ml) in these patients. These real-world data reaffirm the safety and efficacy of dupilumab as a treatment for moderate-to-severe AD among Chinese patients in clinical practice.
