Inhibitors of indoleamine 2,3-dioxygenase to be developed for oncology therapy
SAN DIEGO, March 15, 2016 /PRNewswire/ -- HUYA Bioscience International (HUYA), the leader in accelerating global development of China's pharmaceutical innovations, today announced it has signed an exclusive license with Fudan University for the ex-China rights to a series of novel immuno-oncology drug candidates discovered by Fudan researchers. The agreement includes a panel of novel inhibitors of indoleamine 2,3-dioxygenase (IDO) developed for more than 10 years by the research group of professor Qing Yang of the School of Life Sciences at Fudan University. The IDO pathway is one of several immune response checkpoints thought to play an important role in suppressing T-cell function, allowing tumors to avoid immune surveillance. HUYA plans to advance the products into clinical testing in parallel with the ongoing development of HBI-8000, HUYA's novel histone deacetylase inhibitor, which has been shown to demonstrate its own immunomodulatory properties.
"HUYA was the first company to recognize China's potential as an important source of innovative preclinical stage compounds for worldwide development," said Dr. Mireille Gillings, CEO & Executive Chair of HUYA. "We are pleased to continue HUYA's track record of identifying the most promising new therapeutics from premier institutions in China--in this case with Fudan University, which produces world class researchers and science."
Dr. Li Jin,Vice-president of Fudan University & Academician of Chinese Academy of Sciences said, "We are pleased to be working with HUYA on this program. Their expertise will help to maximize global value and showcase Fudan's world-class research capabilities."
The agreement with Fudan builds in a powerful way relationships with important research institutions in China that are leading a new generation of innovation in Life Sciences.
"These new IDO compounds will dramatically expand our immuno-oncology platform, enabling combination therapy with other drugs to address the limitations of immune therapy due to checkpoint T cell suppression," said Bob Goodenow, PhD, HUYA's CBO.
HBI-8000 is a member of the benzamide class of histone deacetylase (HDAC) inhibitors designed to block the catalytic pocket of Class I HDACs. HBI-8000 is an orally bioavailable, low-nanomolar inhibitor of cancer-associated HDAC enzymes with favorable pharmacology and safety profiles. HBI-8000 inhibits cancer-associated Class I HDAC1, HDAC2, HDAC3, as well as Class IIb HDAC10 at nanomolar concentrations and stimulates accumulation of acetylated histones H3 and H4 in tumor cells. Studies with human-derived tumor cell lines have demonstrated that HBI-8000 inhibits the growth of many tumor cell lines via multiple mechanisms of action, including epigenetic regulation of tumor cell growth and apoptosis, immunomodulatory effects regulating antitumor activity, as well as repression of genes associated with drug resistance. HBI-8000 became the first benzamide HDAC inhibitor approved worldwide when the drug was approved for the treatment of peripheral T cell lymphoma (PTCL) in China, where it is now marketed under the trade name Epidaza. In 2013, HUYA was the first company to use the China-Japan-Korea Tripartite Cooperation Treaty to reach an accelerated development path for Non-Hodgkin's Lymphoma with Japan's Pharmaceutical and Medical Devices Agency (PMDA) based on the China data. In 2015, Japan's Ministry of Health, Labour and Welfare granted HBI-8000 orphan drug designation for the treatment of PTCL. In 2016, HUYA and Eisai Co. Ltd signed an agreement for exclusive rights to HBI-8000 in Japan and 7 other Asian countries. Under the terms of the agreement, HUYA will continue the development in lymphoma through regulatory approval. Eisai will commercialize the product for lymphoma and other future indications including for solid tumors.
