Retrospective Analysis of Lebrikizumab in the Management of Atopic Dermatitis: Insights from Real-World Practice

Atopic dermatitis (AD) is a chronic, relapsing inflammatory disease, significantly impacting a patient's quality of life. To date, a substantial proportion of patients present an insufficient response to available treatment options. Lebrikizumab, a monoclonal antibody targeting interleukin 13, has shown a promising clinical benefit in phase 3 trials, however, real-world data on the effectiveness and safety of lebrikizumab for atopic dermatitis (AD) are limited and mostly restricted to Asian populations. Aim of this study was to evaluate the real-world effectiveness and safety of lebrikizumab in patients with AD.

This retrospective study included 35 patients from a largely homogenous Central European population with moderate to severe Atopic Dermatitis treated with lebrikizumab at the Dermatology Department of the St. Josef-Hospital in Bochum between December 2023 and April 2025. Eczema area and severity index (EASI), SCORing Atopic Dermatitis (SCORAD), peak-pruritus (PP)-numerical rating scale (NRS) and dermatology life quality index (DLQI) were assessed during the treatment.

Lebrikizumab reduced all clinical indices by week 4, with improvements maintained through week 16. At week 24, the achievement rates for EASI-50 (50% reduction in EASI), EASI-75 (75% reduction in EASI) and EASI-90 (90% reduction in EASI) were 100%, 75% and 75%, respectively, and the SCORAD-50 (50% reduction in SCORAD) response rate was 64.2%. The proportions of patients achieving a ≥ 4-point reduction in the PP-NRS and in the DLQI at week 24 were 55.8% and 91.6%, respectively. No new safety signals were observed.

Lebrikizumab demonstrated favorable real-world effectiveness and safety over 24 weeks in patients with moderate-to-severe AD, supporting its use in routine clinical practice.
