Real-World Clinical Experience of Tralokinumab in a Tertiary Centre: An Alternative for Patients with Conjunctivitis on Dupilumab?

Introduction: Tralokinumab, a human IgG4 monoclonal antibody that inhibits the IL-13 pathway, is approved for the treatment of atopic dermatitis. However, real-world data are lacking and are needed to inform its efficacy and safety in broader populations.

Methods: This retrospective study reviewed the Eczema Area and Severity Index (EASI) and Dermatology Life Quality Index (DLQI) at baseline and 16-20 weeks of 39 consecutive patients who received subcutaneous tralokinumab at the label dose in a tertiary centre.

Results: Twenty-nine out of 39 patients had an EASI score recorded after 16-20 weeks. At 16-20 weeks, 65.5% (19/29) of patients achieved EASI 50, 37.9% (11/29) achieved EASI 75, and 27.8% (9/29) achieved EASI 90. DLQI was reduced by an average of - 10.4 points at 16-20 weeks. No serious adverse events were reported. Ocular adverse events were reported in 25.6% (10/39) of the cohort but did not lead to treatment discontinuation. Six out of seven patients that previously experienced conjunctivitis with dupilumab had no recurrence with tralokinumab.

Conclusion: Our study supports using tralokinumab in atopic dermatitis with similar real-world efficacy to that shown in clinical trials. Tralokinumab offers an alternative for patients failing dupilumab because of conjunctivitis.
