title: Review of ubenimex (Bestatin): clinical research.
abstract: An immunomodulating agent, ubenimex (Bestatin) has low toxicity even after long-term oral administration and brings about significant modifications in immunological response. In a cooperative randomized controlled study of Bestatin immunotherapy for adult acute nonlymphocytic leukemia, prolongation of remission duration and survival was achieved with Bestatin immunotherapy combined with remission maintenance chemotherapy. The significant prolongation of remission duration and survival was seen in the Bestatin group, especially in the elderly patients. Randomized controlled studies of Bestatin immunotherapy were performed in solid tumors including malignant melanoma, carcinoma of the lung, stomach, bladder, head and neck and esophagus, and therapeutic benefits regarding disease free-interval or survival were observed in certain types of the above-mentioned cancers; however, Bestatin immunotherapy for these cancers should be further investigated in large-scale controlled studies to confirm its activity.
