Dupilumab treatment in paediatric atopic dermatitis (2 to 18 years): Spanish multicentre retrospective real-life study.
Clinical and Experimental Dermatology 2024 August 3
BACKGROUND: Moderate-to-severe atopic dermatitis (AD) can be difficult to manage in paediatric patients, with few licensed treatments in this age group. Dupilumab is approved for AD in children older than 6 months.
OBJECTIVES: To assess the effectiveness and safety of dupilumab in a real-life cohort of paediatric AD patients in Spain.
METHODS: A multicentre, retrospective real-life study on the effectiveness and safety of dupilumab in patients aged 2 to 18 years old with moderate-to-severe AD was conducted. Demographic and clinical characteristics were analysed, and effectiveness (EASI, IGA, DLQI, NRS itch), safety, and drug survival measures were assessed. A comparison of our results with other real-world outcomes and with clinical trials was made.
RESULTS: Data from 243 patients from 19 centres was collected, with a mean follow-up of 85 weeks. Dupilumab exhibited significant effectiveness, with marked reductions in severity scores from week 4. By week 16, 79.4% of patients reached EASI75 and 40.5% reached EASI90. Mean percentage reduction in EASI was 79.7%. Increasing improvements were observed until week 52, with 85.8% and 49.6% achieving EASI75 and EASI90, respectively. Forty-three patients developed adverse events (AE) (43/243, 17.7%), being the most frequent ocular surface diseases (20/243, 8.2%), injection site reactions (8/243, 3.3%) and facial redness (7/243, 2.9%). Drug survival was high (96.9% and 93.1% after 1 and 2 years of follow-up, respectively), with only 19 (19/243, 7.8%) patients interrupting treatment: 7 (7/243, 2.9%) due to AE, 2 (2/243, 0.82%) due to secondary failure, 5 (5/243, 2.1%) were lost to follow-up and 5 (5/243, 2.1%) entered remission and stopped treatment.
CONCLUSION: Real-life use of dupilumab in paediatric AD showcased sustained effectiveness, high drug survival, and acceptable safety profiles. Longer-term studies are crucial for AE surveillance and how to manage disease remission.
