Active clinical trials for "Anemia, Refractory, with Excess of Blasts"

Phase II trial to study the effectiveness of thalidomide in treating patients who have myelodysplastic syndrome. Thalidomide may improve the immune system's ability to fight myelodysplastic syndrome

The goal of this clinical research study is to find the highest safe dose of the anti-CD33 immunotoxin HuM-195/rGel that can be given to patients with advanced myeloid malignancies. This treatment will be given to patients whose leukemia has not responded to prior chemotherapy.

Randomized phase III trial to compare the effectiveness of different chemotherapy regimens with or without bone marrow transplantation in treating children who have acute myelogenous leukemia or myelodysplastic syndrome. Drugs used in chemotherapy use different ways to stop cancer cells from dividing so they stop growing or die. Combining chemotherapy with bone marrow transplantation may allow the doctor to give higher doses of chemotherapy drugs and kill more cancer cells. It is not yet known which treatment regimen is more effective for acute myelogenous leukemia or myelodysplastic syndrome

The main part of this trial is a phase II study of vosaroxin with azacitidine in older patients with newly diagnosed AML and intermediate or adverse genetic risk or MDS-EB-2. An initial safety run-in phase of the study will be performed administering the study drug vosaroxin with azacitidine in up to 18 patients. After completion of the run-in phase, toxicity and response data will be provided to the external Data and Safety Monitoring Board (DSMB) and the Trial Committee by the Coordinating Investigator. The Trial Committee will decide on the basis of these data and the recommendation of the DSMB on dose modification and the vosaroxin dose for the phase II part of the study, which will include 150 patients in total.

This phase II trial is studying the safety and potential efficacy of infusing non-human leukocyte antigen matched ex vivo expanded cord blood progenitors with one or two unmanipulated umbilical cord blood units for transplantation following conditioning with fludarabine phosphate, cyclophosphamide and total body irradiation, and immunosuppression with cyclosporine and mycophenolate mofetil for patients with hematologic malignancies. Chemotherapy, such as fludarabine phosphate and cyclophosphamide, and total-body irradiation given before an umbilical cord blood transplant stops the growth of leukemia cells and works to prevent the patient's immune system from rejecting the donor's stem cells. The healthy stem cells from the donor's umbilical cord blood help the patient's bone marrow make new red blood cells, white blood cells, and platelets. It may take several weeks for these new blood cells to grow. During that period of time, patients are at increased risk for bleeding and infection. Faster recovery of white blood cells may decrease the number and severity of infections. Studies have shown that counts recover more quickly when more cord blood cells are given with the transplant. We have developed a way of growing or "expanding" the number of cord blood cells in the lab so that there are more cells available for transplant. We are doing this study to find out whether or not giving these expanded cells along with one or two unexpanded cord blood units is safe and if use of expanded cells can decrease the time it takes for white blood cells to recover after transplant. We will study the time it takes for blood counts to recover, which of the two or three cord blood units makes up the patient's new blood system, and how quickly immune system cells return.

RATIONALE: Decitabine may help myelodysplastic cells become more like normal stem cells. PURPOSE: This clinical trial studies differentiation therapy with decitabine in treating patients with myelodysplastic syndrome.

This phase I trial studies the side effects and maximum tolerated dose of yttrium Y 90 anti-cluster of differentiation 45 (CD45) monoclonal antibody BC8 (90Y-BC8) followed by donor stem cell transplant in treating patients with acute myeloid leukemia (AML), acute lymphoblastic leukemia (ALL), or myelodysplastic syndrome (MDS) that is likely to come back or spread. Giving chemotherapy drugs, such as fludarabine phosphate (FLU), and total-body irradiation (TBI) before a donor peripheral blood stem cell (PBSC) or bone marrow transplant helps stop the growth of cancer or abnormal cells and helps stop the patient's immune system from rejecting the donor's stem cells. Radiolabeled monoclonal antibodies, such as 90Y-BC8, can find cancer cells and carry cancer-killing substances to them without harming normal 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 FLU, 90Y-BC8, and TBI before the transplant together with cyclosporine and mycophenolate mofetil after the transplant may stop this from happening.

The purpose of this research study is to determine if the GM-K562/leukemia cell vaccine can be safely given soon after allogeneic marrow or blood stem cell transplant. The GM-K562/leukemia cell vaccine is composed of a cultured cell line that has been genetically modified to secrete GM-CSF, a naturally occuring substance in the body that stimulates the immune system. The vaccine is a mixture of the GM-K562 cells (radiated to prevent them from growing in the participants body) with the participant's previously frozen and killed leukemia cells. By mixing the GM-K562 with the leukemia cells, we would like to study whether this vaccine combination will stimulate the participant's new immune system to recognize and fight against their MDS/AML cancer cells.

This phase II trial is studying how well giving MS-275 together with GM-CSF works in treating patients with myelodysplastic syndrome and/or relapsed or refractory acute myeloid leukemia. MS-275 may stop the growth of cancer cells by blocking some of the enzymes needed for cell growth and by blocking blood flow to the cancer. Colony-stimulating factors, such as GM-CSF, may increase the number of immune cells found in bone marrow or peripheral blood. Giving MS-275 together with GM-CSF may be an effective treatment for myelodysplastic syndrome and acute myeloid leukemia

This study will examine the effect intravenously administered rigosertib has on the relationship between bone marrow blasts response and overall survival in myelodysplastic syndromes (MDS) patients who have 5-30% bone marrow blasts and who progressed on or after treatment with azacitidine or decitabine.
