The Company focuses on discovering and developing small molecule drugs directed against tumor and immune cell targets that control key metabolic pathways in the tumor microenvironment. It is engaged in developing agents that take advantage of the metabolic requirements of tumor cells and cancer-fighting immune cells, such as cytotoxic T-cells. Its lead product candidate, CB-839, is a critical enzyme in tumor cells. Its other product candidate, CB-1158, which is an enzyme that depletes the amino acid arginine, a key metabolic nutrient for T-cells. Its lead preclinical program in tumor immunology is directed at developing inhibitors of the enzyme arginase and may provide a therapeutic agent for the target. CB-839 is a selective, reversible and orally bioavailable inhibitor of human glutaminase. Hexokinase is an enzyme in the pathway that allows cancer cells to convert glucose to energy to fuel cancer cell growth."
