This phase I trial studies the side effects and best dose of sorafenib tosylate when given
together with riluzole in treating patients with advanced solid tumors or melanoma. Riluzole
may stop or slow the growth of tumor cells. Sorafenib tosylate may stop the growth of tumor
cells by blocking some of the enzymes needed for cell growth. Giving riluzole together with
sorafenib tosylate may kill more tumor cells.
Minimum age: 18 Years.
Maximum age: N/A.
Gender(s): Both.
