GTI-2040, Oxaliplatin, and Capecitabine in Treating Patients With Locally Advanced or Metastatic Colorectal Cancer or Other Solid Tumors

This phase I trial is studying the side effects and best dose of capecitabine when given together with GTI-2040 and oxaliplatin in treating patients with locally advanced or metastatic colorectal cancer or other solid tumors. Drugs used in chemotherapy, such as oxaliplatin and capecitabine, work in different ways to stop tumor cells from dividing so they stop growing or die. GTI-2040 may increase the effectiveness of chemotherapy by making tumor cells more sensitive to the drugs. Giving GTI-2040 together with oxaliplatin and capecitabine may kill more tumor cells
