MedKoo CAT#: 205920
Description: VAL-083 is a bi-functional alkylating agent, with potential antineoplastic activity. Upon administration, VAL-083 crosses the blood brain barrier (BBB) and appears to be selective for tumor cells. This agent alkylates and crosslinks DNA which ultimately leads to a reduction in cancer cell proliferation. In addition, VAL-083 does not show cross-resistance to other conventional chemotherapeutic agents and has a long half-life in the brain.

VAL-083 has demonstrated activity in cyclophosphamide, BCNU and phenylanine mustard resistant cell lines and no evidence of cross-resistance has been encountered in published clinical studies. Based on the presumed alkylating functionality of VAL-083, published literature suggests that DNA repair mechanisms associated with Temodar and nitrosourea resistance, such as 06-methylguanine methyltransferace (MGMT), may not confer resistance to VAL-083. VAL-083 readily crosses the blood brain barrier where it maintains a long half-life in comparison to the plasma. Published preclinical and clinical research demonstrates that VAL-083 is selective for brain tumor tissue. VAL-083 has been assessed in multiple studies as chemotherapy in the treatment of newly diagnosed and recurrent brain tumors. In published clinical studies, VAL-083 has previously been shown to have a statistically significant impact on median survival in high grade gliomas when combined with radiation vs. radiation alone. The main dose-limiting toxicity related to the administration of VAL-083 in previous clinical studies was myelosuppression. (source: http://www.delmarpharma.com/product_development_programs/val083/).
