Dupilumab Improves Clinical Scores in Pediatric Patients Aged 2 to <18 Years with Uncontrolled Atopic Dermatitis: A Single‐Center, Real‐World Study

Abstract

Dupilumab is the first biologic agent approved for treatment of moderate to severe atopic dermatitis (AD). Phase 3 clinical trials have shown the efficacy and safety in AD children. However, real‐world evidence is still scarce. Thirty‐nine pediatric patients with uncontrolled AD who regularly received dupilumab were included in a single‐center retrospective study. Eight patients (20.5%) were aged 2 to <6 years, fifteen (38.5%) were 6 to <12 years, and sixteen were 12 to <18 years. Changes in clinical AD scores (EASI, SCORAD, P‐NRS, CDLQI, and POEM) at baseline, week 4 (W4), W10, and W16, as well as safety data were collected. At W16, the average EASI values dropped from 29.0 ± 16.2 to 5.1 ± 4.7, and 22 patients (73.3%) achieved 75% improvement in EASI. 16 patients (53.3%) achieved 75% improvement in SCORAD. Significant reduction was also observed in the changes of P‐NRS, CDLQI, and POEM values. Notably, the change of clinical scores was similar among three age subgroups. At W16, the mean percent decreases in EASI for 2 to <6 years, 6 to <12 years, and 12 to <18 years, and subgroups were 67.3%, 78.5%, and 83.9%, respectively. A total of three cases of adverse effects were recorded, with conjunctivitis seen in two >6‐year‐old patients and the injection site reaction in one <6‐year‐old child. Dupilumab exhibited favorable efficacy and safety profile, including the 2 to <6 years old subgroup.
