SAN MATEO, Calif. and SINGAPORE and TOKYO, June 22, 2023 (GLOBE NEWSWIRE) -- ASLAN Pharmaceuticals Pte Ltd (“ASLAN”, Nasdaq: ASLN), a clinical-stage, immunology-focused biopharmaceutical company developing innovative treatments to transform the lives of patients, and a leading Japanese pharmaceutical company Zenyaku Kogyo Co. Ltd. (“Zenyaku”), a subsidiary of privately held Zenyaku Holdings Co., Ltd. (“Zenyaku Holdings”), today announced a strategic licensing agreement granting Zenyaku exclusive rights to develop and commercialize eblasakimab in atopic dermatitis (AD) and all other indications in Japan.

ASLAN will receive an upfront payment of $12 million and is eligible to receive an additional $3 million from Zenyaku upon achieving certain pre-agreed conditions for the TREK-AD Phase 2b trial data readout and delivery of the clinical study report, up to $29.5 million in development milestones and up to $94 million in commercial milestones. Zenyaku will make double digit royalty payments to ASLAN on net sales of eblasakimab in percentages ranging up to low twenties. Under the terms of the licensing agreement, Zenyaku will be responsible for all development and commercialization activities for eblasakimab in Japan. Zenyaku plans to initiate a Phase 1 study of eblasakimab in Japan in the first half of 2024. ASLAN retains an option that can be exercised at any time to reacquire the rights to eblasakimab in Japan in the future.

Zenyaku has extensive product development, regulatory and marketing expertise in dermatology and immunology indications in Japan. A long-term partner of leading global pharmaceutical companies, Zenyaku markets Rituxan® (rituximab) in the Japanese market, and conducts all clinical development in Japan. Zenyaku has successfully obtained regulatory approvals in Japan for Rituxan® in 11 additional indications, including several oncology and dermatology indications, 7 of which are unique to the Japanese market.

“We are extremely pleased to partner with Zenyaku, a leading Japanese pharmaceutical company with exceptional clinical and life cycle management expertise. Zenyaku has established a successful track record in developing novel biologics and gaining regulatory approvals, as well as successfully commercializing dermatology therapies in Japan,” said Dr Carl Firth, CEO, ASLAN Pharmaceuticals. “The burden of AD is significant and growing in Japan – there are 5 million people living with the disease1 and millions more who live with other Type 2 driven diseases. As we approach late-stage development of eblasakimab globally, it was important for us to identify a partner like Zenyaku who can apply its experience to accelerate the development of eblasakimab in Japan.”

“As the burden of living with moderate-to-severe AD continues to grow in Japan, there is an increasing demand for more innovative, effective and convenient treatments from physicians and patients,” saidKoichi Hashimoto, President and Chief Executive Officer of Zenyaku Kogyo. “We are very pleased to partner with ASLAN as we expand our dermatology portfolio, and eblasakimab’s unique mechanism of action and the potential for a safe, efficacious, and convenient treatment for moderate-to-severe AD, represents an important and strategic addition to our pipeline. Based on the positive data generated to date, we believe that eblasakimab has the potential to be a first-in-class differentiated therapy for AD in Japan.”

About eblasakimab

Eblasakimab is a potential first-in-class monoclonal antibody targeting the IL-13 receptor subunit of the Type 2 receptor, a key pathway driving several allergic inflammatory diseases. Eblasakimab’s unique mechanism of action enables specific blockade of the Type 2 receptor and has the potential to improve upon current biologics used to treat allergic disease. By blocking the Type 2 receptor, eblasakimab prevents signaling through both interleukin 4 (IL-4) and interleukin 13 (IL-13) – the key drivers of inflammation in atopic dermatitis (AD). Positive results from a Phase 1b multiple-ascending-dose study established proof-of-concept for eblasakimab and supported its potential as a novel, differentiated treatment for AD. ASLAN is currently conducting TREK-AD, a Phase 2b trial to evaluate eblasakimab in biologic naïve moderate-to-severe AD patients, with topline readout expected in early July 2023. ASLAN is also investigating eblasakimab in dupilumab experienced, moderate-to-severe AD patients in the Phase 2 trial TREK-DX, with data expected in the first quarter of 2024.
