INTRODUCTION: Atopic dermatitis (AD) is a chronic inflammatory skin disease often requiring continuous therapy. The objective with the ECZTEND trial was to assess the long-term safety and efficacy of tralokinumab treatment.
METHODS: ECZTEND was a multicountry, open-label, 5-year extension trial conducted from September 2018 to July 2024 in patients (≥ 12 years) with moderate-to-severe AD who had received up to 1 year of tralokinumab treatment in a parent trial. Patients were eligible regardless of previous randomization (tralokinumab or placebo) or treatment response in the parent trial. The primary endpoint was the number of treatment-emergent adverse events (TEAEs) through week 268. Key secondary endpoints were Investigator's Global Assessment (IGA) and Eczema Area and Severity Index (EASI) through week 248.
RESULTS: In total, 1672 patients were enrolled (4466.2 patient-years of exposure; median 2.6 years). Overall, 68.4% of patients (n = 1143) completed the trial period they consented to; 7.1% (n = 117) discontinued owing to lack of efficacy; and 4.2% (n = 72) owing to adverse events. The TEAE incidence rate was 114.3/100 patient-years with a pattern consistent with that observed in the parent trials albeit at lower rates. The majority (> 97%) of TEAEs were nonserious and of mild or moderate severity. Most (> 80%) were assessed as not related to tralokinumab by the investigator and resolved by the end of the trial. Common TEAEs (≥ 5%) included nasopharyngitis, atopic dermatitis, coronavirus infection, upper respiratory tract infection, conjunctivitis, and headache. The proportions of patients with IGA 0/1 and EASI-75/EASI-90 increased during the first 16 weeks and then remained stable through week 248 at ≥ 50% for IGA 0/1 and EASI-90, and ≥ 80% for EASI-75.
CONCLUSIONS: Long-term tralokinumab treatment for up to 6 years (parent trials plus ECZTEND) in patients ≥ 12 years with moderate-to-severe AD was well tolerated and maintained long-term efficacy. A graphical abstract is available for this article.
