A Phase 2, Open-label Trial of the Safety and Biological Effect of Subcutaneous IRX-2 (With Cyclophosphamide, Indomethacin, and Zinc) in Patients With Resectable Cancer of the Head and Neck

IRX-2 is designed to activate your own body's immune system so that it can better fight the invasion of head and neck cancer. In pre-clinical studies, IRX-2 has been shown to activate a number of different cells of the immune system. IRX-2 was previously tested in a study of 13 patients with advanced head and neck cancer who had been previously treated and failed chemotherapy and/or radiation therapy. The trials were specifically designed to test the safety of IRX-2. Researchers found that IRX-2 did not appear to have major side effects. Also, the researchers believed that further study in less advanced head and neck cancer patients could be useful in obtaining more data on the safety of IRX-2 as well as data on possible effects on tumors and on patient survival.

Stanford is not currently accepting new patients for this trial. You may want to check to see if other locations are recruiting.
