Vemurafenib With Sorafenib Tosylate or Crizotinib in Treating Patients With Advanced Malignancies With BRAF Mutations

This phase I clinical trial studies vemurafenib with sorafenib tosylate or crizotinib in treating patients with advanced malignancies with BRAF mutations. Sorafenib tosylate and crizotinib may stop the growth of cancer cells by blocking some of the enzymes needed for cell growth. Sorafenib tosylate may also stop the growth of advanced malignancies by blocking blood flow to tumors. Drugs used in chemotherapy, such as vemurafenib, work in different ways to stop the growth of cancer cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. Giving vemurafenib together with sorafenib tosylate or crizotinib may kill more cancer cells.
