aTyr Pharma Presents Preclinical Research Showing Effects of ATYR2810 in Lung and Breast Cancer at the 2021 AACR Virtual Annual Meeting
Findings demonstrate tumor inhibitory effects of ATYR2810 when used as a monotherapy or in combination with chemotherapy in models of non-small cell lung cancer.
ATYR2810 used in combination with chemotherapy or bevacizumab increased anti-tumor effects in triple-negative breast cancer model.
The posters present findings from preclinical studies, conducted in collaboration with Dr.
“The data presented in these posters affirm the therapeutic potential of ATYR2810 for aggressive cancer and provide a compelling rationale for evaluating the efficacy of ATYR2810 in patients,” said Dr.
“These findings build upon our preclinical work related to ATYR2810 and strengthen our understanding of blocking VEGF-mediated NRP2 signaling as a potential approach to inhibiting tumor growth,” said

About ATYR2810
aTyr is developing ATYR2810 as a potential therapeutic for certain aggressive tumors where Neuropilin-2 (NRP2) is implicated. ATYR2810 is a fully humanized monoclonal antibody that is designed to specifically and functionally block the interaction between NRP2 and one of its primary ligands, VEGF. ATYR2810 is the first Investigational New Drug (IND) candidate to arise from aTyr’s in-house research program designing monoclonal antibodies to selectively target the NRP2 receptor and its associated signaling pathways. NRP2 is a cell surface receptor that is highly expressed in certain tumors, in the lymphatic system and on key immune cells implicated in cancer progression. Increased NRP2 expression is associated with worse outcomes in many cancers. Preclinical data suggest that ATYR2810 could be effective against certain types of solid tumors. ATYR2810 is currently undergoing IND-enabling studies.
About aTyr
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.
