Interleukin-12, Paclitaxel, and Trastuzumab in Treating Patients With Solid Tumors

Phase I trial to study the effectiveness of interleukin-12, paclitaxel, and trastuzumab in treating patients who have solid tumors. Interleukin-12 may kill tumor cells by stopping blood flow to the tumor and by stimulating a person's white blood cells to kill cancer cells. Drugs used in chemotherapy use different ways to stop tumor cells from dividing so they stop growing or die. Monoclonal antibodies such as trastuzumab can locate tumor cells and either kill them or deliver tumor-killing substances to them without harming normal cells. Combining interleukin-12, chemotherapy, and monoclonal antibody therapy may kill more tumor cells.
