Torque, an immuno-oncology company developing Deep Primed cellular therapies with pharmacologic control to direct immune power deep within the tumor microenvironment, announced today preclinical data for the company's Deep-Primed IL-15 and Deep-Primed IL-12 programs demonstrating their activity compared to systemically administered IL-15 and IL-12. These data were presented at the 2018 American Association for Cancer Research (AACR) Annual Meeting in Chicago.
“Deep Primed” is a term trademarked by Torque. Deep-Priming uses advanced material engineering to anchor immune-stimulatory drugs directly to the surface of multi-targeted, antigen-primed T cells to activate both the adaptive and innate immune system with pharmacologic control in the tumor microenvironment. This approach does not require genetic engineering and enables tunable loading of precise doses of cytokines onto the surface of T cells to deliver sustained and controlled immune activation.
"Both Il-15 and IL-12 are potent cytokines capable of inducing strong anti-tumor immune responses, yet their clinical use as systemic therapies is limited by the potential for severe toxicities," said Thomas Andresen, PhD, Chief Scientific Officer of Torque. "Anchoring these powerful immune activators to the surface of T cells that traffic to tumors is a unique approach to direct immune power in the tumor microenvironment. These preclinical studies demonstrate superior efficacy for this approach compared to systemic administration of these same cytokines and are the foundation for the first clinical trials that will begin later this year for Deep IL-15."
