Building on the observation that tumor regression can occur in the setting of bacterial infection, we have developed a proprietary platform that exploits bacteria’s natural ability to activate both innate and adaptive cellular immune pathways. Leveraging our novel insights into the levels and ratios of activating signals needed to safely elicit a broad immune response, we are creating and advancing a pipeline of proprietary, attenuated and killed non-pathogenic gram-negative bacterial candidates designed to be widely accessible, with broad anti-tumor and anti-viral activity.
