Epacadostat (INCB024360) is an orally available hydroxyamidine and inhibitor of indoleamine 2,3- dioxygenase (IDO1). It shows little activity against other related enzymes such as IDO2 or tryptophan 2,3-dioxygenase (TDO). Epacadostat displays potential immune modulating and antineoplastic activities. Epacadostat has been tested in phase II and III studies for the treatment of malignant melanoma, fallopian tube cancer, non-small cell lung cancer, ovarian cancer, peritoneal cancer, solid tumors, pancreatic cancer. The most common detected adverse events were fatigue, nausea, decreased appetite, vomiting, constipation, abdominal pain, diarrhea, dyspnea, back pain, and cough.
