Real-World Evidence of Tralokinumab Effectiveness and Safety: A Systematic Review and Meta-analysis

Background

Tralokinumab, a first-in-class and second biologic approved for treating moderate-to-severe atopic dermatitis in adolescents and adults, has demonstrated consistent efficacy and safety across multiple clinical trials.

Objective

We aimed to assess the real-world effectiveness and safety of tralokinumab by performing a systematic review and meta-analysis on the real-world evidence of tralokinumab.

Methods

We systematically searched PubMed and EMBASE from inception until 28 July, 2024 for observational studies describing the effectiveness and safety of tralokinumab for the treatment of atopic dermatitis. The primary outcome was the proportion of patients achieving a ≥75% improvement in the Eczema Area and Severity Index (EASI-75) after 16 weeks and secondary outcomes included the proportion of patients achieving EASI-50 and EASI-90 and the proportion of patients experiencing adverse events.

Results

Nineteen unique studies encompassing 911 bio-naïve and bio-experienced patients with atopic dermatitis treated with tralokinumab were included. After 16 weeks of treatment, 82%, 59% and 26% of patients achieved EASI-50, EASI-75 and EASI-90, respectively, and the proportion of patients developing conjunctivitis was 3.2%.

Conclusions

Tralokinumab demonstrates strong effectiveness and good tolerability in real-world settings, with a high proportion of patients achieving a clinical response and adverse events being observed only infrequently.
