Real-world clinical efficacy of nemolizumab in Japanese patients with atopic dermatitis

Abstract

Nemolizumab was approved in Japan in August 2022 to treat patients with atopic dermatitis (AD). The study objective was to evaluate its effectiveness in controlling AD symptoms in the real world postmarketing. Eleven Japanese patients with AD treated with nemolizumab were assessed at 12 weeks for clinical manifestations, AD scores Visual Analog Scale and Eczema Area and Severity Index, and serum biomarkers. Visual Analog Scale and Eczema Area and Severity Index scores were significantly decreased by 80% and 66.4%, showing nemolizumab improved both itch and skin lesions. However, several serum AD biomarkers did not change during treatment with nemolizumab.
