Health-related quality of life with tralokinumab in moderate-to-severe atopic dermatitis: A phase 2b randomized study.

BACKGROUND: Atopic dermatitis (AD) is associated with a substantial burden on quality of life (QoL). OBJECTIVE: To evaluate the effects of tralokinumab on health-related QoL in patients with moderate-to-severe AD using patient-reported outcomes. METHODS: This was a phase 2b, randomized, double-blind, placebo-controlled, dose-ranging study in adults with moderate-to-severe AD. The patients received subcutaneous tralokinumab or placebo (1:1:1:1) every 2 weeks for 12 weeks and class 3 topical corticosteroid cream or ointment at least once daily from the run-in to end of follow-up. Patient-reported outcome end points were change from baseline to week 12 in the Dermatology Life Quality Index (dermatology life quality index (DLQI); prespecified secondary objective), the Short Form 36 Health Survey (SF-36) version 2, and sleep interference numeric rating scale score (prespecified exploratory objectives). RESULTS: A total of 204 patients were randomized to placebo (n = 51) or tralokinumab (45 mg, n = 50; 150 mg, n = 51; 300 mg, n = 52). Tralokinumab 300 mg every 2 weeks improved total Dermatology Life Quality Index vs placebo at week 12 (placebo-adjusted mean change, -3.51 [95% confidence interval, -6.00 to -1.02]). At week 12, both the mental component summary (4.23 [0.98-7.47]) and the physical component summary (4.26 [1.83-6.69]) and all 8 domains of the Short Form 36 Health Survey were improved in patients treated with tralokinumab 300 mg vs placebo. Sleep interference was improved at week 12 with all tralokinumab doses vs placebo. CONCLUSION: Tralokinumab improved health-related QoL in patients with moderate-to-severe atopic dermatitis, providing further evidence of the value of targeting interleukin-13 in such patients.
