Humanized Monoclonal Antibody 3F8 and Sargramostim in Treating Patients with Recurrent Osteosarcoma

Trial Status: closed to accrual

This phase II trial studies how well humanized monoclonal antibody 3F8 (Hu3F8) and sargramostim work in treating patients with bone cancer (osteosarcoma) that has come back (recurrent). Humanized monoclonal antibody 3F8 is a monoclonal antibody that may interfere with the ability of tumor cells to grow and spread. Colony-stimulating factors, such as sargramostim, may increase the number of granulocytes (kinds of white blood cells that are able to kill cancer cells). Sargramostim increases the number of other kinds of white blood cells that may help attack tumor cells. Sargramostim may also make humanized monoclonal antibody 3F8 more effective against osteosarcoma. Giving humanized monoclonal antibody 3F8 together with sargramostim may be an effective treatment for patients with osteosarcoma.
