Analytical Performance of a Real-time PCR-based Assay for V600 Mutations in the BRAF Gene, Used as the Companion Diagnostic Test for the Novel BRAF Inhibitor Vemurafenib in Metastatic Melanoma

Melanomas frequently harbor BRAFV600 mutations. Vemurafenib (RG7204/PLX4032), a small-molecule inhibitor of mutant BRAF, has shown striking clinical efficacy in BRAFV600 mutant melanoma, creating the need for a well-validated companion diagnostic to select patients for treatment. We describe analyti
