Active clinical trials for "Leukemia, Myeloid, Chronic-Phase"

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 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.

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: Giving chemotherapy before a donor bone marrow transplant helps stop the growth of cancer cells. It also helps stop the patient's immune system from rejecting the donor's stem cells. Also, imatinib mesylate may stop the growth of cancer cells by blocking the enzymes needed for cancer cell growth. Interferon alfa may interfere with the growth of cancer cells and slow the growth of cancer. 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. It is not yet known which treatment regimen is most effective in treating chronic phase chronic myelogenous leukemia. PURPOSE: This randomized phase III trial is studying imatinib mesylate with or without interferon alfa or cytarabine to see how well it works compared with interferon alfa followed by donor stem cell transplant in treating patients with newly diagnosed chronic phase chronic myelogenous 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.

This is a phase III study of BMS-354825 in subjects with chronic phase Philadelphia chromosome or BCR-ABL positive chronic myelogenous leukemia, who are resistant or intolerant to imatinib mesylate (Gleevec).

The goal of this clinical research study is to learn if an experimental agent, AMN107 (nilotinib), can help to control CML in chronic phase. The safety of this experimental agent will also be studied.

RATIONALE: Bone marrow transplantation may be able to replace immune cells that were destroyed by the chemotherapy or radiation therapy that was used to kill cancer cells. PURPOSE: Phase II trial to study the effectiveness of allogeneic bone marrow transplantation in treating patients who have multiple myeloma, chronic phase chronic myelogenous leukemia, or agnogenic myeloid metaplasia.

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.

Phase 3, 2-arm, randomized, open label trial. Patients will be randomized to receive bosutinib or imatinib for the duration of the study.
