Turnstone Biologics Inc. is a clinical-stage biotechnology company based in Ottawa, Canada, with an additional office in New York. Founded in 2015, the company is dedicated to advancing innovative viral immunotherapies aimed at improving cancer patient survival. Its lead product, RIVAL-01, utilizes a vaccinia virus backbone that encodes several immunomodulators, including Flt3 ligand, anti-CTLA-4 antibody, and IL-12 cytokine, which work together to enhance immune activity and optimize the tumor microenvironment for effective cancer treatment. Additionally, Turnstone Biologics is developing next-generation tumor-infiltrating lymphocyte (TIL) therapies by isolating and expanding the most potent and tumor-reactive T cells from patients' tumors, thereby harnessing the body's own immune system to combat solid tumors. Through these innovative approaches, Turnstone Biologics aims to deliver breakthrough cancer immunotherapies that significantly improve clinical outcomes for patients.
