Riluzole in Combination With mFOLFOX6 and Bevacizumab in Treating Patients With Metastatic Colorectal Cancer

This phase I trial is to find out the best dose, possible benefits, and/or side effects of riluzole and how well it works in combination with standard of care mFOLFOX6 and bevacizumab in treating patients with colorectal cancer that has spread to other places in the body (metastatic). Riluzole is a well-tolerated oral medication that has demonstrated it may make chemotherapy work better. Chemotherapy drugs, such as oxaliplatin, leucovorin calcium and fluorouracil, work in different ways to stop the growth of \[cancer/tumor\] cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. Bevacizumab is an antibody that targets the blood vessel by blocking the activity of a protein called vascular endothelial growth factor alpha (VEGF-A). It helps to make the mFOLFOX6 more effective. Giving riluzole, mFOLFOX6, and bevacizumab may kill more tumor cells compared to mFOLFOX6 and bevacizumab alone in treating patients with colorectal cancer.
