Scientific Background:Indoleamine 2,3-dioxygenase (IDO) is an enzyme that catalyzes the degradation of L-tryptophan to N-formylkynurenine. This immunomodulatory enzyme has been shown to allow tumor cells to escape the immune system by depletion of L-Trp in the microenvironment of cell A wide range of human cancers overexpress human IDO (hIDO).
