aTyr Pharma and its Hong Kong Subsidiary, Pangu BioPharma, Achieve Milestones for First Year of Government Grant to Develop Bispecific Antibody Platform
Key milestones achieved for the first year of the project included building out a highly skilled research team to establish an innovative antibody discovery platform at HKUST. An integral part of this project was the development and implementation of a novel single-cell antibody discovery approach which has so far yielded numerous candidate high-affinity NRP2/co-receptor antibodies that are currently being screened in functional assays. The second year of the project aims to identify the most productive pairings, optimize mid-scale production/purification and prioritize lead candidate bispecific antibodies based on activity in therapeutically relevant cell-based assays.
“We are very pleased with the progress of Pangu and HKUST in the first year of this important project,” said
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.
aTyr is a biotherapeutics company engaged in the discovery and development of innovative medicines based on novel biological pathways. aTyr’s 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. aTyr’s 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 inflammatory lung diseases.
