TRC102 and Temozolomide for Relapsed Solid Tumors and Lymphomas

Background: \- Methoxyamine hydrochloride (TRC102) is a new cancer treatment drug that may help improve the results of chemotherapy. It blocks tumor cells' attempts to repair damaged deoxyribonucleic acid (DNA), which may allow chemotherapy to kill the cells more easily. Researchers want to see how well it works with temozolomide, a chemotherapy drug that is designed to damage tumor cell DNA. These drugs will be given to people who have advanced solid tumors or lymphomas that have not responded to earlier treatments. Objectives: \- To test the safety and effectiveness of TRC102 and temozolomide for advanced solid tumors and lymphomas. Eligibility: \- Individuals at least 18 years of age who have advanced solid tumors or lymphomas that have not responded to earlier treatments. Design: * Participants will be screened with a physical exam and medical history. Blood and urine samples will be collected. Tumor samples may also be collected. The size and location of the tumors will be determined with imaging studies. * Participants will take TRC102 and temozolomide for 28-day cycles of treatment. They will take temozolomide and TRC 102 by mouth once a day on days 1-5. Participants will keep a diary to record doses and any side effects. * Treatment will be monitored with frequent blood tests and imaging studies. Tumor samples will also be collected. * Participants will continue their treatment as long as the cancer does not grow and there are no severe side effects.
