Filter by:Recent studies of conventional chemotherapy for infants with high-risk hematologic malignancies show that the long-term disease-free survival is low. Although blood and marrow stem cell transplantation using an HLA identical sibling has improved the outcome for these children, less than 25% have this donor source available. Another option is haploidentical transplantation using a partially matched family member donor (i.e. parental donor). Although haploidentical transplantation has proven curative for some patients, this procedure has been hindered by significant complications, primarily regimen-related toxicity including infection and graft versus host disease (GVHD). Building on prior institutional trials, this study will provide patients a haploidentical graft depleted of T lymphocytes using the investigational device, CliniMACS selection system. One week after the transplant procedure, patients will also receive an infusion of additional donor derived white blood cells called Natural Killer (NK) cells in an effort to decrease risks for rejection of the graft, disease relapse, and regimen related toxicity. The primary objective of the study is to evaluate 1 year survival in infants with high risk hematologic malignancies who receive this study treatment.
This phase II trial is studying the side effects and best dose of alemtuzumab when given together with fludarabine phosphate and total-body irradiation followed by cyclosporine and mycophenolate mofetil in treating patients who are undergoing a donor stem cell transplant for hematologic cancer. Giving low doses of chemotherapy, such as fludarabine phosphate, a monoclonal antibody, such as alemtuzumab, and radiation therapy before a donor stem cell transplant helps stop the growth of cancer cells. Giving chemotherapy or radiation therapy before or after transplant also stops the patient's immune system from rejecting the donor's bone marrow stem cells. The donated stem cells may replace the patient's immune cells and help destroy any remaining cancer cells (graft-versus-tumor effect). Sometimes the transplanted cells from a donor can also make an immune response against the body's normal cells. Giving cyclosporine and mycophenolate mofetil after the transplant may stop this from happening.
Due to progressive therapy intensification in the four consecutive studies AML-BFM 78, 83, 93 and 98, prognosis for children with acute myeloid leukemia (AML) has improved steadily. In spite of the intensified therapy, rates of morbidity and mortality have remained unchanged or have even decreased. Against the background that about 40% of the patients still die from immediate causes of an underlying disease relapse or of nonresponse, it seems to be justifiable to intensify therapy - especially for high-risk patients - which on its parts will require an optimization of supportive measures. As the present risk stratification into standard- (SR) and high-risk (HR) patients has proved effective, we will pursue the risk-adapted therapy strategy. The aim of the study is to improve prognosis in children with AML by intensification of cytostatic therapy and to evaluate by randomisation the equivalence of a prophylactic central nervous system (CNS) irradiation with a total dose of 18 Gy versus 12 Gy.
RATIONALE: Giving chemotherapy and total-body irradiation before a donor bone marrow transplant or peripheral blood stem cell transplant helps stop the growth of cancer cells. It also helps stop the patient's immune system from rejecting the donor's stem cells. When the healthy stem cells from a donor are infused into the patient they may help the patient's bone marrow make stem cells, red blood cells, white blood cells, and platelets. Sometimes the transplanted cells from a donor can make an immune response against the body's normal cells. Giving antithymocyte globulin before transplant and cyclosporine after transplant may stop this from happening. PURPOSE: This randomized clinical trial is studying how well giving antithymocyte globulin together with cyclosporine works in preventing graft-versus-host disease in patients who are undergoing chemotherapy with or without radiation therapy followed by donor stem cell transplant for acute lymphoblastic leukemia or acute myeloid leukemia.
This randomized phase III trial is studying total-body irradiation (TBI) and fludarabine phosphate to see how it works compared with TBI alone followed by donor stem cell transplant in treating patients with hematologic cancer. Giving low doses of chemotherapy, such as fludarabine phosphate, and radiation therapy before a donor stem cell transplant helps stop the growth of cancer cells. It also stops the patient's immune system from rejecting the donor's stem cells. The donated stem cells may replace the patient's immune system cells and help destroy any remaining cancer cells (graft-versus-tumor effect). Sometimes the transplanted cells from a donor can also make an immune response against the body's normal cells. Giving cyclosporine and mycophenolate mofetil after transplant may stop this from happening. It is not yet known whether TBI followed by donor stem cell transplant is more effective with or without fludarabine phosphate in treating hematologic cancer.
RATIONALE: Monoclonal antibodies can locate tumor cells and either kill them or deliver tumor-killing substances to them without harming normal cells. PURPOSE: Phase II trial to study the effectiveness of monoclonal antibody in treating patients who have acute myelogenous leukemia that did not respond to standard treatment given in clinical trial PDL 195-301.
RATIONALE: Drugs used in chemotherapy use different ways to stop tumor cells from dividing so they stop growing or die. Monoclonal antibodies can locate tumor cells and either kill them or deliver tumor-killing substances to them without harming normal cells. It is not yet known if chemotherapy is more effective with or without monoclonal antibody therapy for acute myelogenous leukemia. PURPOSE: Randomized phase III trial to compare the effectiveness of combination chemotherapy with or without monoclonal antibody therapy in treating patients who have refractory or relapsed acute myelogenous leukemia.
RATIONALE: Giving combination chemotherapy before a peripheral blood stem cell transplant stops the growth of cancer cells by stopping them from dividing or killing them. After treatment, stem cells are collected from the patient's blood or bone marrow and stored. More chemotherapy or radiation therapy is given prepare the bone marrow for the stem cell transplant. The stem cells are then returned to the patient to replace the blood-forming cells that were destroyed by the chemotherapy and radiation therapy. Interleukin-2 may stimulate the patient's white blood cells to kill cancer cells. PURPOSE: This randomized phase III trial is studying two different regimens of combination chemotherapy, interleukin-2, and peripheral stem cell transplant and comparing them to see how well they work in treating patients with acute myeloid leukemia.
RATIONALE: Drugs used in chemotherapy use different ways to stop cancer cells from dividing so they stop growing or die. Combining more than one drug may kill more cancer cells. PURPOSE: Phase II trial to study the effectiveness of combination chemotherapy consisting of cytarabine plus idarubicin in treating patients who have relapsed acute myelogenous leukemia.
RATIONALE: Drugs used in chemotherapy use different ways to stop cancer cells from dividing so they stop growing or die. Combining more than one drug may kill more cancer cells. It is not yet known which combination chemotherapy regimen is more effective in treating older patients with acute myeloid leukemia. PURPOSE: Randomized phase III trial to compare the effectiveness of two different combination chemotherapy regimens in treating older patients with acute myeloid leukemia in first remission.
