About PLX4032 (RG7204)—A Personalized Medicine for Cancer Treatment

PLX4032 is a novel, oral small molecule for the treatment of melanoma and other cancers harboring the V600E mutation of the BRAF kinase gene. This defect is present in approximately 50 percent of melanoma skin cancers, 10 percent of colorectal cancers and about eight percent of all solid tumors. Plexxikon and Roche are co-developing PLX4032 under their 2006 license and collaboration agreement. A companion diagnostic also is being co-developed along side of PLX4032 to determine the BRAF mutation status of patients.
