Kineta Presents New Preclinical Data at the 2020 SITC Annual Meeting on its VISTA Antagonist Antibodies

Preclinical data demonstrates that VISTA is a novel target checkpoint against immunosuppressive myeloid cells

Seattle, WA — (November 12, 2020) Kineta, Inc., a clinical stage biotechnology company focused on the development of novel immunotherapies in oncology and neuroscience, announced today the presentation of new preclinical data on its VISTA antagonist antibodies at the Society for Immunotherapy of Cancer (SITC) 35th Anniversary Annual Meeting, taking place November 9-14, 2020. Thierry Guillaudeux, PhD, Senior Vice President Immuno-oncology at Kineta, will present a poster on the new preclinical data on the company’s fully human anti-VISTA antibodies.

“VISTA is a novel immuno-oncology checkpoint that works against myeloid cells, which are a key driver of the immunosuppressive tumor microenvironment” said Thierry Guillaudeux. “I am excited to present these new data on Kineta’s fully human lead antibodies that have demonstrated strong potency and binding against VISTA and offer the potential to become an effective immunotherapy for patients with cancer”.

VISTA is a key driver of the immunosuppressive tumor microenvironment (TME) and is overexpressed on myeloid-derived suppressor cells (MDSC) and regulatory T cells (Tregs). It is a critical myeloid cell immune-checkpoint, and VISTA blockade can reprogram suppressive myeloid cells and reactivate antitumor immune function. Blocking VISTA activates an immune cell cascade that increases T cell effector functions to drive an efficient anti-tumor response. Preclinical studies have demonstrated single agent anti-VISTA activity but also demonstrate that targeting VISTA in combination with PD-1, PD-L1 or CTLA-4 can significantly improve the efficacy of those checkpoint inhibitors.
