Led by Barry Labinger, CEO, Checkmate is a clinical stage biotechnology company pursuing a novel approach to specifically activating the innate arm of the immune system to recognize and ultimately destroy tumor cells in combination with other therapies. The company is leveraging its expertise and the vast body of knowledge in the field of CpG oligonucleotides to validate an approach designed to combine the ability of CpG DNA to activate an anti-tumor T cell response with checkpoint inhibition to overcome a tumor’s ability to mute the immune response.
