Plexxikon Announces PLX4032 Phase I Clinical Trial Results

Plexxikon Inc. reports positive clinical data from a Phase 1 extension study of PLX4032 (RG7204) in metastatic melanoma patients. PLX4032 targets the BRAFV600E mutation that occurs in about 50 percent of melanomas and about eight percent of solid tumors. Tumor shrinkage has been observed in nearly all of the currently evaluable patients in the extension study, reflecting a 70 percent response rate. Plexxikon and Roche are co-developing PLX4032 under their 2006 license and collaboration agreement.
