Active clinical trials for "Leukemia, Myeloid, Acute"

RATIONALE: Drugs used in chemotherapy, such as cytarabine and daunorubicin, work in different ways to stop the growth of cancer cells, either by killing the cells or by stopping them from dividing. 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. It is not yet known whether cytarabine and daunorubicin followed by gemtuzumab ozogamicin is more effective than cytarabine and daunorubicin in treating acute myeloid leukemia or myelodysplastic syndromes. PURPOSE: This randomized phase III trial is studying cytarabine and two different doses of daunorubicin to see how well they work compared to cytarabine and daunorubicin followed by gemtuzumab ozogamicin in treating older patients with acute myeloid leukemia or myelodysplastic syndromes.

This phase II trial studies how well tacrolimus and mycophenolate mofetil works in preventing graft-versus-host disease in patients who have undergone total-body irradiation (TBI) with or without fludarabine phosphate followed by donor peripheral blood stem cell transplant for hematologic cancer. Giving low doses of chemotherapy, such as fludarabine phosphate, and TBI before a donor peripheral blood 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 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 tacrolimus and mycophenolate mofetil after the transplant may stop this from happening.

Based on success in other diseases, the Fred Hutchinson Cancer Research Center (FHCRC) has developed a transplant procedure for Fanconi anemia (FA), which does not completely destroy the patient's remaining bone marrow. It should also be less harmful (toxic). Researchers wish to test whether this approach can overcome the graft failure often seen when bone marrow or peripheral blood stem cells from an unrelated donor are used. Researchers also will look at whether the procedure is less toxic than a conventional bone marrow transplant (BMT).

The primary objectives of this study are: To evaluate whether the addition of amifostine will allow for the safe administration of idarubicin at a dose of 21 mg/m² in combination with standard-dose ara-C in older patients with newly diagnosed, previously untreated acute myeloid leukemia (AML); and To estimate the complete remission rate of induction therapy with amifostine, idarubicin (21 mg/m²), plus ara-C or induction therapy with idarubicin (12 mg/m²) plus ara-C in this patient population.

This phase I/II trial studies whether stopping cyclosporine before mycophenolate mofetil is better at reducing the risk of life-threatening graft-versus-host disease (GVHD) than the previous approach where mycophenolate mofetil was stopped before cyclosporine. The other reason this study is being done because at the present time there are no curative therapies known outside of stem cell transplantation for these types of cancer. Because of age or underlying health status, patients may have a higher likelihood of experiencing harm from a conventional blood stem cell transplant. This study tests whether this new blood stem cell transplant method can be made safer by changing the order and length of time that immune suppressing drugs are given after transplant.

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 I trial to study the effectiveness of combining irinotecan with cytarabine in treating patients who have refractory or recurrent acute myeloid leukemia or chronic myelogenous leukemia.

This phase I/II trial is studying the side effects of biological therapy and to see how well it works in treating patients with advanced myelodysplastic syndrome, chronic myeloid leukemia, acute myeloid leukemia, or acute lymphoblastic leukemia. Biological therapies, including immunotherapy, can potentially be used to stimulate the immune system and stop cancer cells from growing. Immunotherapy given to patients who have undergone donor stem cell transplantation may be a way to eradicate remaining cancer cells

This phase I trial is studying the side effects and best dose of tipifarnib and bortezomib in treating patients with acute leukemia or chronic myelogenous leukemia in blast phase. Tipifarnib and bortezomib may stop the growth of cancer cells by blocking some of the enzymes needed for cell growth. Giving tipifarnib together with bortezomib may kill more cancer cells.

The purpose of this trial is to to determine the safety and effectiveness of therapeutic combination - Clofarabine and Cytarabine for the treatment of AML and MDS.

This randomized phase II trial studies how well giving tacrolimus and mycophenolate mofetil (MMF) with or without sirolimus works in preventing acute graft-versus-host disease (GVHD) in patients undergoing donor stem cell transplant for hematologic cancer. Giving low doses of chemotherapy, such as fludarabine phosphate, and total-body-irradiation before a donor peripheral blood 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 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 MMF and tacrolimus with or without sirolimus after transplant may stop this from happening.
