Filter by:RATIONALE: Giving chemotherapy before a donor umbilical cord blood transplant (UCBT) helps stop the growth of cancer and abnormal cells and helps stop the patient's immune system from rejecting the donor's stem cells. When the stem cells from an unrelated donor, that do not exactly match the patient's blood, 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 and mycophenolate mofetil after transplant may stop this from happening. PURPOSE: This phase II trial is studying how well donor umbilical cord blood stem cell transplant works in treating patients with hematologic malignancies.
This pilot research trial studies biomarkers in bone marrow samples from pediatric patients with high risk acute myeloid leukemia. Studying samples of bone marrow from patients with cancer in the laboratory may help doctors identify and learn more about biomarkers related to cancer.
This phase I trial is studying the safety and potential efficacy of infusing non-human leukocyte antigen (HLA) matched ex vivo expanded cord blood progenitors following treatment with clofarabine and cytarabine for patients with acute myeloid leukemia (AML). The combination of clofarabine, cytarabine (Ara-C) and granulocyte colony-stimulating factor (G-CSF) has been tested in earlier studies for the treatment of acute myeloid leukemia. In these previous clinical trials, this combination of drugs has been shown to have an anti-leukemia effect. However, the combination of clofarabine and Ara-C is profoundly myelosuppressive and immunosuppressive causing periods of neutropenia potentially lasting more than three weeks. During this period, patients are at increased risk of infections that can result in an increased risk of death. G-CSF is a growth factor that is used to help the white blood cells recover more quickly, but even with G-CSF, the use of clofarabine and Ara-C is often limited by the need to take long breaks between treatments to allow blood counts to recover. In our lab we have developed a method of growing or "expanding" blood stem cells (cells that give rise to the blood system) from umbilical cord blood. We are doing this study to find out if giving these expanded cells after chemotherapy is safe, helps the blood system recover more quickly from chemotherapy to allow shorter breaks between treatments, and decreases the risk of infection
This phase II trial studies how well donor peripheral blood stem cell (PBSC) transplant works in treating patients with hematologic malignancies. Cyclophosphamide when added to tacrolimus and mycophenolate mofetil is safe and effective in preventing severe graft-versus-host disease (GVHD) in most patients with hematologic malignancies undergoing transplantation of bone marrow from half-matched (haploidentical) donors. This approach has extended the transplant option to patients who do not have matched related or unrelated donors, especially for patients from ethnic minority groups. The graft contains cells of the donor's immune system which potentially can recognize and destroy the patient's cancer cells (graft-versus-tumor effect). Rejection of the donor's cells by the patient's own immune system is prevented by giving low doses of chemotherapy (fludarabine phosphate and cyclophosphamide) and total-body irradiation before transplant. Patients can experience low blood cell counts after transplant. Using stem cells and immune cells collected from the donor's circulating blood may result in quicker recovery of blood counts and may be more effective in treating the patient's disease than using bone marrow.
The purpose of this study is to test the safety of vorinostat (Zolinza) and azacitidine (Vidaza) when combined with gemtuzumab ozogamicin (GO) at different dose levels. These drugs increase the effect of GO against leukemia cells in the test tube, but we don't know yet whether they also increase the anti-leukemia effect of GO in people.
This randomized phase II trial is studying two different schedules of alvocidib to compare how well they work when given together with cytarabine and mitoxantrone in treating patients with newly diagnosed acute myeloid leukemia. Drugs used in chemotherapy, such as alvocidib, cytarabine, and mitoxantrone, work in different ways to stop the growth of cancer cells, either by killing the cells or by stopping them from dividing. It is not yet known which schedule of alvocidib is more effective when given together with cytarabine and mitoxantrone in treating patients with acute myeloid leukemia.
This phase II trial studies the side effects and best dose of bortezomib when given together with daunorubicin and cytarabine and to see how well it works in treating older patients with previously untreated acute myeloid leukemia. Bortezomib may stop the growth of cancer cells by blocking some of the enzymes needed for cell growth. Drugs used in chemotherapy, such as daunorubicin and cytarabine, work in different ways to stop the growth of cancer cells, either by killing the cells or by stopping them from dividing. Giving bortezomib together with combination chemotherapy may kill more cancer cells.
RATIONALE: Vorinostat may stop the growth of cancer cells by interfering with various proteins needed for cell growth. Monoclonal antibodies, such as gemtuzumab ozogamicin (GO), can block cancer growth in different ways. GO finds cancer cells and helps kill them by carrying a cancer-killing substance to them. Giving vorinostat together with gemtuzumab ozogamicin may kill more cancer cells. PURPOSE: This phase II trial is studying how well giving vorinostat together with gemtuzumab ozogamicin works in treating older patients with previously untreated acute myeloid leukemia.
This phase II trial is studying the side effects and best dose of bortezomib and to see how well it works when given together with combination chemotherapy in treating younger patients with recurrent, refractory, or secondary acute myeloid leukemia (AML). Bortezomib may stop the growth of cancer cells by blocking some of the enzymes needed for cell growth. Drugs used in chemotherapy, such as idarubicin, cytarabine, and etoposide, work in different ways to stop the growth of cancer cells, either by killing the cells or by stopping them from dividing. Giving more than one drug (combination chemotherapy) together with bortezomib may kill more cancer cells
This phase II trial is studying the side effects of giving azacitidine together with gemtuzumab ozogamicin to see how well it works in treating older patients with previously untreated acute myeloid leukemia. Drugs used in chemotherapy, such as azacitidine, work in different ways to stop the growth of cancer cells, either by killing the cells or by stopping them from dividing. Azacitidine may also stop the growth of cancer cells by blocking some of the enzymes needed for cell growth. Monoclonal antibodies, such as gemtuzumab ozogamicin, can block cancer growth in different ways. Some block the ability of cancer cells to grow and spread. Others find cancer cells and help kill them or carry cancer-killing substances to them. Giving azacitidine together with gemtuzumab ozogamicin may kill more cancer cells.
