Real-World Clinical Practice Evaluation of Tralokinumab in Atopic Dermatitis: A 52-Week Multi-Center Retrospective...

Background: Tralokinumab is an anti-IL-13 monoclonal antibody approved for moderate-to-severe atopic dermatitis (AD). While pivotal trials have demonstrated its efficacy, real-world data remain limited. Methods: We conducted a retrospective, multi-center study in the Basque Country including 109 adults with moderate-to-severe AD treated with tralokinumab. Clinical outcomes (EASI, IGA, BSA, DLQI, and NRS-pruritus/sleep) were assessed at baseline, weeks 16, 24, and 52. Results: EASI-75/90/100 responses were 66%/44%/16% at week 16 and increased to 83%/70%/34% at week 52. Pruritus NRS decreased from 7.1 to 3.1 and DLQI from 17.8 to 9.0. Adverse events were uncommon, with only three cases of conjunctivitis (two discontinued). Conclusions: Our findings support tralokinumab as a safe and effective long-term therapy for AD in routine practice. Results were consistent with, or superior to, pivotal and other RWE studies.
