Pilot Study of Allogeneic/Syngeneic Blood Stem Cell Transplantation in Patients With High-Risk and Recurrent Pediatric Sarcomas
In Brief
A Phase 2 clinical trial evaluating F-18 Fluorodeoxyglucose, therapeutic allogeneic lymphocytes, and 13 other interventions for Sarcoma. Completed, enrolled 60 participants across 1 site.
Detailed Summary
This study will examine the safety and effectiveness of stem cell transplantation for treating patients with sarcomas (tumors of the bone, nerves, or soft tissue). Stem cells are immature cells in the bone marrow and blood stream that develop into blood cells. Stem cells transplanted from a healthy donor travel to the patient's bone marrow and begin producing normal cells. In patients with certain cancers, such as leukemia and lymphoma, the donor's immune cells attack the patient's cancer cells in what is called a "graft-versus-tumor" effect, contributing to cure of the disease. This study will determine whether this treatment can be used successfully to treat patients with sarcomas. Patients between 4 and 35 years of age with a sarcoma that has spread from the primary site or cannot be removed surgically, and for whom effective treatment is not available, may be eligible for this study. Candidates must have been diagnosed by the age of 30 at the time of enrollment. They must have a matched donor (usually a sibling). Participants undergo the following procedures: Donors: Stem cells are collected from the donor. To do this, the hormone granulocyte colony stimulating factor (G-CSF) is injected under the skin for several days to move stem cells out of the bone marrow into the bloodstream. Then, the cells are collected by apheresis. In this procedure the blood is drawn through a needle placed in one arm and pumped into a machine where the stem cells are separated out and removed. The rest of the blood is returned to the donor through a needle in the other arm. Patients: For patients who do not already have a central venous catheter (plastic tube), one is placed into a major vein. This tube can stay in the body the entire treatment period for giving medications, transfusing blood, , withdrawing blood samples, and delivering the donated stem cells. Before the transplant procedure, patients receive from one to three cycles of "induction" chemotherapy, with each cycle consisting of 5 days of fludarabine, cyclophosphamide, etoposide, doxorubicin, vincristine, and prednisone followed by at least a 17-day rest period. All the drugs are infused through the catheter except prednisone, which is taken by mouth. After the induction therapy, the patient is admitted to the hospital for 5 days of chemotherapy with high doses of cyclophosphamide, melphalan, and fludarabine. Two days later, the stem cells are infused. The anticipated hospital stay is about 3 weeks, but may be longer if complications arise. Patients are discharged when their white cell count is near normal, they have no fever or infection, they can take sufficient food and fluids by mouth, and they have no signs of serious graft-versus-host disease (GVHD)-a condition in which the donor's cells "see" the patient's cells as foreign and mount an immune response against them. After hospital discharge, patients are followed in the clinic at least once or twice weekly for a medical history, physical exam, and blood tests for 100 days. They receive medications to prevent infection and GVHD and, if needed, blood transfusions. If GVHD has not developed by about 120 days post transplant, patients receive additional white cells to boost the immune response. After 100 days, follow-up visits may be less frequent. Follow-up continues for at least 5 years. During the course of the study, patients undergo repeated medical evaluations, including blood tests and radiology studies, to check on the cancer and on any treatment side effects. On four occasions, white blood cells may be collected through apheresis to see if immune responses can be generated against the sarcomas treated in this study. Positron emission tomography (PET) scans may be done on five occasions. This test uses a radioactive material to produce images useful in detecting primary tumors and cancer that has spread.
