China NMPA Approves Antengenes IND Application For ATG-019 In Patients With Advanced Solid Tumors Or NHL

Antengene Corporation Limited, a biopharmaceutical company dedicated to discovering, developing and commercializing global first-in-class and/or best-in class therapeutics in hematology and oncology, announced that the National Medical Products Administration (NMPA) has approved the Investigational New Drug (IND) application for a phase I clinical trial to evaluate safety and tolerability of ATG-019 (monotherapy or combined with niacin ER) in patients with advanced solid tumors or non-Hodgkin's lymphoma (NHL) in China.

As an orally bioavailable dual PAK4/NAMPT inhibitor, ATG-019 can lead to antitumor effects through energy depletion, inhibition of DNA repair, cell cycle arrest, inhibition of proliferation, and ultimately cell apoptosis. Hematological and solid tumor cells that are dependent on both PAK4 and NAMPT pathways may be susceptible to single-agent anti-tumor activity by ATG-019. ATG-019 has clear preclinical anti-tumor activity and a superior pharmacokinetics (PK) and safety profile making it an attractive novel drug candidate. Antengene has recently been conducting a Phase I clinical trial (TEACH) of ATG-019 in advanced solid tumors and NHL in Taiwan.

"The NMPA's approval of the IND application for ATG-019 indicates the potential of this drug to be applied to Chinese patients. We look forward to initiating the first clinical trial of ATG-019 in mainland China," said Dr. Jay Mei, founder, chairman and CEO of Antengene. "ATG-019 is an orally available dual PAK4/NAMPT inhibitor that achieves synergistic antitumor effects through the co-inhibition of the two pathways. We believe that ATG-019, as a novel agent under investigation, can potentially provide an additional treatment option for patients with advanced solid tumor and NHL."

ATG-019 is a global first-in-class oral dual PAK4/NAMPT inhibitor developed by Karyopharm Therapeutics Inc. (NASDAQ: KPTI). Antengene reached an exclusive agreement of cooperation and authorization with Karyopharm and obtained the exclusive development and commercialization rights of ATG-019 in multiple Asia-Pacific markets, including Greater China, South Korea, Australia, New Zealand and ASEAN countries.

PAK4 is a signaling protein regulating numerous fundamental cellular processes, including intracellular transport, cellular division, cell shape and motility, cell survival, immune defense and the development of cancer. PAK4 interacts with many key signaling molecules involved in cancer development such as beta-catenin, CDC42, Raf-1, BAD and myosin light chain.
