aTyr Pharma and its Hong Kong Subsidiary, Pangu BioPharma, Announce Government Grant to Fund Bispecific Antibody Development Platform – BioSpace

Grant awarded by the Hong Kong Government's Innovation and Technology Commission under the Partnership Research Program

Two-year project will initially focus on development of new bi-specific antibodies targeting NRP2

SAN DIEGO, March 24, 2020 (GLOBE NEWSWIRE) --aTyr Pharma Inc., Inc. (Nasdaq: LIFE), a biotherapeutics company engaged in the discovery and development of innovative medicines based on novel immunological pathways, today announced that the companys Hong Kong subsidiary, Pangu BioPharma Limited (Pangu), together with the Hong Kong University of Science and Technology (HKUST), has been awarded a grant of approximately $750,000 to build a high-throughput platform for the development of bi-specific antibodies. Initially the research focus will be on diseases, including cancer, in which Neuropilin-2 (NRP2) overexpression is strongly implicated. The two-year project is being funded by the Hong Kong Governments Innovation and Technology Commission (ITC) under the Partnership Research Program (PRP). The PRP aims to support research and development projects undertaken by companies in collaboration with local universities and public research institutions. The grant will fund approximately 50% of the total estimated project cost, with aTyr contributing the remaining 50%.

Partnering with leading research institutions, such as HKUST, remains a key component of our long-term growth strategy, and we are optimistic that this collaboration, with important financial assistance from ITC, could eventually lead to breakthroughs in the treatment of cancer and other serious diseases where improved treatment options are needed," said Sanjay S. Shukla, M.D., M.S., president and chief executive officer of aTyr. We would like to thank the ITC for this grant to help fund development of a platform that we believe can yield new bi-specific antibody candidates. As we continue to advance our understanding of the role of NRP2 in immunology and cancer, we believe therapeutics selectively targeting NRP2 pathways have the potential to become a new class of therapies. The fact that NRP2 interacts with various co-receptor molecules makes it a prime target for bi-specific antibodies that can target both receptors simultaneously.

Dr. Mingjie Zhang, Chair Professor of the Division of Life Science and Kerry Holdings Professor of Science at HKUST and project coordinator of the Pangu collaboration, commented, We are excited to expand the collaboration between Pangu and HKUST to establish cutting-edge antibody discovery and engineering capabilities. This project has the potential to further solidify the role that Hong Kongs translational science and early discovery capabilities can play in the development of potentially life-changing therapies.

About NRP2

Neuropilin-2 (NRP2) is a cell surface receptor that plays a key role in lymphatic development and in regulating inflammatory responses. In many forms of cancer, high NRP2 expression is associated with worse outcomes. NRP2 can interact with multiple ligands and co-receptors through distinct domains to influence their functional roles, making it a potential drug target with multiple distinct therapeutic applications. NRP2 interacts with type 3 semaphorins and plexins to impact inflammation and with forms of vascular endothelial growth factor (VEGF) and their receptors, to impact lymphangiogenesis. In addition, NRP2 modulates interactions between CCL21 and CCR7 potentially impacting homing of dendritic cells to lymphoid organs. aTyr is currently investigating NRP2 receptor biology, both internally and in collaboration with key academic thought leaders, as a novel target for new product candidates for a variety of diseases, including cancer and inflammation.

About aTyr

aTyr is a biotherapeutics company engaged in the discovery and development of innovative medicines based on novel immunological pathways. aTyrs research and development efforts are concentrated on a newly discovered area of biology, the extracellular functionality and signaling pathways of tRNA synthetases. aTyr has built a global intellectual property estate directed to a potential pipeline of protein compositions derived from 20 tRNA synthetase genes and their extracellular targets. aTyrs primary focus is ATYR1923, a clinical-stage product candidate which binds to the neuropilin-2 receptor and is designed to down-regulate immune engagement in interstitial lung diseases.
