About CoFactor

CoFactor (ANX-510) is a folate-based biomodulator drug designed to replace leucovorin as the preferred method to enhance the activity and reduce associated toxicity of the widely used cancer chemotherapy 5-fluorouracil (5-FU). In comparison to leucovorin, CoFactor creates more stable binding of the active form of 5-FU to the target enzyme, thymidylate synthase (TS). CoFactor bypasses the metabolic pathway required by leucovorin to deliver the active form of folate, allowing 5-FU to work more effectively. CoFactor is in Phase 3 and Phase 2b clinical trials for the treatment of metastatic colorectal cancer, as well as in a Phase 2 clinical trial for the treatment of advanced breast cancer.
