HOLON, Israel, Feb. 6, 2018 /PRNewswire/ -- Compugen Ltd. (NASDAQ: CGEN), a leader in predictive discovery and development
"The publication of the discovery and functional validation of ILDR2 and its potential therapeutic applications in a prestigious peer-reviewed journal is a scientific recognition of the significance of our findings. Compugen is the first to publish data on ILDR2 as a new immune checkpoint with a potential therapeutic role in autoimmune diseases and cancer immunotherapy, each presenting first-in-class therapeutic opportunities," stated Anat Cohen-Dayag, PhD, President and CEO of Compugen. "This is the third novel immune checkpoint we disclosed, following PVRIG and TIGIT. Similar to our discovery of the PVRIG/PVRL2 pathway in immuno-oncology and its potential clinical significance, here too, we identified a new pathway with robust and diversified data supporting its mechanism-of-action and broad therapeutic potential, both for the treatment of autoimmune diseases and for cancer immunotherapy."
The publication1 led by Compugen's scientists, describes the computational discovery approach leading to the discovery of ILDR2 as a novel immune checkpoint. The experimental validation of the role of this protein as a negative regulator of T cell activity was established both internally at Compugen as well as in collaboration with scientists from three leading academic institutions. The publication reports the beneficial effects of CGEN-15001 in an animal model of rheumatoid arthritis (RA), as well as in a translational assay utilizing blood cells from RA patients, that mimics the deleterious interactions of immune cells in the RA synovium. The latter study was led by Prof. Iain B. McInnes, Muirhead Chair of Medicine and Director of Institute of Infection, Immunity and Inflammation at the University of Glasgow.
Prof. McInnes, co-author of the Compugen publication, said, "These findings assign a new role to the ILDR2 protein, whose immune-related function was not previously known, and uncover a novel pathway involved in immune regulation. The expression pattern of this protein, as well as its mechanism of action elucidated in these two publications, involving the induction of immune tolerance and restoration of immune homeostasis, offer a potential novel treatment option for autoimmune and chronic inflammatory conditions. Both traits are highly desired in a broad range of autoimmune diseases and are not well addressed with currently available therapies, which are often globally immunosuppressive."
Preclinical research led by Compugen's scientists together with Profs. Stephen Miller, Ph.D., and Joseph R. Podojil, Ph.D., both from the Department of Microbiology-Immunology and Interdepartmental Immunobiology Center, Feinberg School of Medicine, Northwestern University2, and published in an additional paper, demonstrates the potential of ILDR2-Fc fusion protein to address autoimmune and inflammatory conditions as well as the mechanism of action underlying this activity. The data show the potent and long-lasting immunomodulatory activity of ILDR2-Fc fusion protein in animal models of multiple sclerosis (R-EAE) and type 1 diabetes, and its ability to promote engraftment in an animal model of bone marrow transplantation. This work reveals the mechanism of action of ILDR2-Fc in ameliorating autoimmunity through regulation of immune homeostasis and re-establishment of immune tolerance to the disease-causing antigen, by the induction of regulatory T cells (Tregs).
Prof. Miller commented, "Our findings point to a compelling mode of action for this Fc fusion protein in autoimmune diseases. In animals, this protein induced a long-term response following a short treatment duration through the promotion of regulatory T cells activating an immune tolerance induction mechanism. We also showed that this immune tolerance induction, addressing the autoimmune disease, is specific to the antigen driving the autoimmune disease and did not trigger a global non-specific inhibition of immune responses, thus potentially maintaining the immune response against infections and neo-malignancies."
