Palleon Pharmaceuticals Announces Preclinical Data from EAGLE Platform to be Presented at the AACR Special Conference on Tumor Immunology and Immunotherapy

WALTHAM, Mass., November 26, 2018 – Palleon Pharmaceuticals, a leading biotech company focused on developing drugs that target Glyco-Immune Checkpoints to treat cancer, today announced an oral presentation of preclinical data from its EAGLE platform at the American Association for Cancer Research (AACR) Special Conference on Tumor Immunology and Immunotherapy, taking place in Miami from November 27 – 30, 2018.

Li Peng, Ph.D., Vice President, Biotherapeutics Discovery at Palleon, will present the poster – “A novel immunomodulatory strategy of targeting Glyco-Immune Checkpoints using EAGLE technology to treat cancer” – on Friday, November 30, between 8:00 – 9:30 a.m., during a Special Session on Novel Targets, Pathways and Tools.


Palleon’s EAGLE platform enables the development of drugs that inhibit Glyco-Immune Checkpoints by disabling the immunosuppressive function of tumor cell surface glycans. The critical challenge in this area arises from the complexity, heterogeneity and rapidly evolving nature of the tumor glycans. The EAGLE platform employs an enzyme/antibody bi-specific construct, which removes terminal sialic acids, the molecules that are responsible for suppressing the immune system, from cancer cell surface glycans in the tumor micro-environment. This enzymatic approach uniquely overcomes tumor glycan heterogeneity and makes tumors vulnerable to both innate and adaptive immune responses.

About Glyco-Immune Checkpoints

Cancer uses multiple pathways to evade the immune system, and Glyco-Immune Checkpoints are a significant and under-appreciated axis of immunosuppression in cancer. Tumors exploit Glyco-Immune Checkpoints through the alteration of glycans on the surface of their cells, impairing both innate and adaptive immune cells and resulting in a broad, comprehensive suppression of the anti-tumor immune response. Glyco-Immune Checkpoints had been overlooked relative to other anti-cancer strategies due to the complexity of glycoscience, and, until recently, the lack of scientific tools to demonstrate its relevance to immuno-oncology. Palleon has assembled the technologies needed to overcome these barriers and make drug development in this field possible.

About Palleon Pharmaceuticals

Palleon Pharmaceuticals is the leading biotechnology company focused on developing drugs that target Glyco-Immune Checkpoints to treat cancer. The company’s proprietary EAGLECONVERGENCE and HYDRA platforms integrate technologies and insights from world-renowned scientific leaders in the fields of glycoscience and human immunology to create a novel approach to treating cancer. By targeting multiple immune cell types, Glyco-Immune Checkpoint inhibition will tackle resistance to existing immuno-oncology agents and make possible a wider range of rational combination therapies to treat cancer. Palleon has several cancer drug discovery programs underway. Beyond oncology, other important areas where Glyco-Immune Checkpoints may play a role include infectious diseases, neurodegeneration, inflammation, and fibrosis. The company is advancing its pipeline and development programs with a $47.6 million Series A financing from leading biotech venture investors SR One, Pfizer Ventures, Vertex Ventures HC, Takeda Ventures, and AbbVie Ventures.
