Active clinical trials for "Leukemia, Myeloid, Accelerated Phase"

This phase I trial studies the side effects and the best dose of sunitinib malate in treating human immunodeficiency virus (HIV)-positive patients with cancer receiving antiretroviral therapy. Sunitinib malate may stop the growth of cancer cells by blocking some of the enzymes needed for cell growth and by blocking blood flow to the tumor.

This phase I trial is studying the side effects and best dose of 7-hydroxystaurosporine when given together with perifosine in treating patients with relapsed or refractory acute leukemia, chronic myelogenous leukemia, or myelodysplastic syndromes. 7-Hydroxystaurosporine may stop the growth of cancer cells by blocking some of the enzymes needed for cell growth. Drugs used in chemotherapy, such as perifosine, work in different ways to stop the growth of cancer cells, either by killing the cells or by stopping them from dividing. Giving 7-hydroxystaurosporine together with perifosine may kill more cancer cells.

This phase I multicenter feasibility trial is studying the safety and potential efficacy of infusing ex vivo expanded cord blood progenitors with one unmanipulated umbilical cord blood unit for transplantation following conditioning with fludarabine, cyclophosphamide and total body irradiation (TBI), and immunosuppression with cyclosporine and mycophenolate mofetil (MMF) for patients with hematologic malignancies. Chemotherapy, such as fludarabine and cyclophosphamide, and TBI 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 are more likely to recover more quickly if increased numbers of 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 unexpanded cord blood unit 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 cord blood units makes up the patient's new blood system, and how quickly immune system cells return

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.

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.

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.

RATIONALE: Giving low doses of chemotherapy, such as fludarabine, and radiation therapy 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). Giving an infusion of the donor's T cells (donor lymphocyte infusion) or interferon alfa after the transplant may help increase this 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. PURPOSE: This phase II trial is studying how well giving fludarabine together with radiation therapy works in treating patients who are undergoing donor stem cell transplant for chronic phase or accelerated phase chronic myelogenous leukemia.

RATIONALE: STI571 may interfere with the growth of cancer cells and may be effective treatment for chronic myelogenous leukemia. PURPOSE: Phase II trial to study the effectiveness of STI571 in treating patients who have accelerated phase chronic myelogenous leukemia.

This clinical trial studies fludarabine phosphate, low-dose total body irradiation, and donor stem cell transplant in treating patients with hematologic malignancies or kidney cancer. Giving chemotherapy drugs, such as fludarabine phosphate, and total-body irradiation before a donor peripheral blood stem cell transplant helps stop the growth of cancer cells. It may also stop the patient's immune system from rejecting the donor's stem cells. The donated stem cells may replace the patient's immune cells and help destroy any remaining cancer cells (graft-versus-tumor effect). Giving an infusion of the donor's T cells (donor lymphocyte infusion) after the transplant may help increase this effect. Sometimes the transplanted cells from a donor can also make an immune response against the body's normal cells. Giving cyclosporine before the transplant and cyclosporine and mycophenolate mofetil after the transplant may stop this from happening.

This phase II trial studies how well an umbilical cord blood transplant with added sugar works with chemotherapy and radiation therapy in treating patients with leukemia or lymphoma. Giving chemotherapy and total-body irradiation before a donor umbilical cord blood transplant helps stop the growth of cells in the bone marrow, including normal blood-forming cells (stem cells) and cancer 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. The umbilical cord blood cells will be grown ("expanded") on a special layer of cells collected from the bone marrow of healthy volunteers in a laboratory. A type of sugar will also be added to the cells in the laboratory that may help the transplant to "take" faster.
