Japan Tobacco Inc. (JT) (TSE:2914) and Torii Pharmaceutical Co., Ltd. (Torii) (TSE:4551) announced the top-line results of a Phase 3 comparative study for JTE-061, conducted in Japan, for the treatment of atopic dermatitis. JT signed an exclusive license agreement with Dermavant Sciences GmbH (Dermavant) for the development and commercialization of tapinarof, a topical, therapeutic aryl hydrocarbon receptor agonist (JTE-061), for dermatological diseases and conditions in Japan. JT also signed an exclusive license agreement with Torii for co-development and commercialization of JTE-061 in Japan. JTE-061 is being developed for patients with atopic dermatitis and plaque psoriasis.

This study is a double blind, randomized and parallel-group comparison study to evaluate the efficacy and safety of JTE-061 cream in comparison to vehicle over 8 weeks in adult and adolescent patients with atopic dermatitis. The top-line results show that the IGA response1 at week 8, the primary endpoint of efficacy, has met statistical superiority to vehicle. In addition, JTE-061 cream demonstrated higher EASI75 achievement rate2 at Week 8, key secondary endpoint of efficacy, compared with vehicle. The safety of JTE-061 cream was confirmed and there were no observed issues of tolerability for the cream.

JT and Torii will aim to submit a manufacturing and marketing application for JTE-061 cream in Japan, based on the results of the study and other Phase 3 studies currently being conducted. Separately, Phase 3 clinical studies in patients with plaque psoriasis and Phase 2 clinical studies in pediatric patients (aged 2 to ?11 years) with atopic dermatitis are ongoing and being conducted in Japan. Tapinarof cream developed by Dermavant has been approved for the treatment of plaque psoriasis on May 23, 2022 in the U.S.
