Active clinical trials for "Myelodysplastic-Myeloproliferative Diseases"

RATIONALE: Doxercalciferol may improve low blood cell counts and decrease the need for blood transfusions and may be an effective treatment for myelodysplastic syndrome or chronic myelomonocytic leukemia. PURPOSE: Phase II trial to study the effectiveness of doxercalciferol in treating patients who have myelodysplastic syndrome or chronic myelomonocytic leukemia.

RATIONALE: Giving low doses of chemotherapy 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) 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 immunosuppressive therapy before or after the transplant may stop this from happening. PURPOSE: This phase II trial is studying how well chemotherapy followed by donor peripheral stem cell transplant works in treating patients with hematologic cancer or aplastic anemia.

This phase I trial is studying the side effects and best dose of decitabine and FR901228 in treating patients with relapsed or refractory leukemia, myelodysplastic syndromes or myeloproliferative disorders. Drugs used in chemotherapy, such as decitabine and FR901228, work in different ways to stop the growth of cancer cells, either by killing the cells or by stopping them from dividing. FR901228 may also stop the growth of cancer cells by blocking some of the enzymes needed for cell growth and by blocking blood flow to the cancer. Giving decitabine together with FR901228 may kill more cancer cells.

RATIONALE: Drugs used in chemotherapy, such as amifostine, work in different ways to stop the growth of cancer cells, either by killing the cells or by stopping them from dividing. PURPOSE: This phase II trial is studying how well amifostine works in treating young patients with newly diagnosed de novo myelodysplastic syndromes.

RATIONALE: Giving low doses of chemotherapy 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 that have been treated in the laboratory 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 tacrolimus before and after transplant may stop this from happening. PURPOSE: This phase I trial is studying the side effects and best dose of donor lymphocytes when given after alemtuzumab and combination chemotherapy in treating patients who are undergoing donor stem cell transplant for hematologic cancer.

RATIONALE: Drugs used in chemotherapy, such as fludarabine, work in different ways to stop cancer cells from dividing so they stop growing or die. 3-AP may help fludarabine kill more cancer cells by making them more sensitive to the drug. PURPOSE: This phase I trial is studying the side effects and best dose of fludarabine when given together with 3-AP in treating patients with relapsed or refractory acute leukemia, chronic leukemia, or high-risk myelodysplastic syndrome.

RATIONALE: Donor peripheral stem cell transplantation may be able to replace bone marrow and immune cells that were destroyed by chemotherapy. Sometimes the transplanted cells from a donor are rejected by the body's normal cells. Eliminating the T cells from the donor cells before transplanting them and giving cyclosporine may prevent this from happening. PURPOSE: This phase I trial is studying the side effects of T-cell-depleted allogeneic stem cell transplantation after immunoablative induction chemotherapy and reduced-intensity transplantation conditioning (chemotherapy) in treating patients with hematologic malignancies.

This phase II trial is studying the side effects and best dose of alemtuzumab when given together with fludarabine phosphate and total-body irradiation followed by cyclosporine and mycophenolate mofetil in treating patients who are undergoing a donor stem cell transplant for hematologic cancer. Giving low doses of chemotherapy, such as fludarabine phosphate, a monoclonal antibody, such as alemtuzumab, and radiation therapy before a donor stem cell transplant helps stop the growth of cancer cells. Giving chemotherapy or radiation therapy before or after transplant also stops the patient's immune system from rejecting the donor's bone marrow stem cells. The donated stem cells may replace the patient's immune 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 the transplant may stop this from happening.

RATIONALE: Drugs used in chemotherapy, such as clofarabine and cyclophosphamide, 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) may kill more cancer cells. PURPOSE: This phase I trial is studying the side effects and best dose of clofarabine and cyclophosphamide in treating patients with relapsed or refractory acute leukemia, chronic myelogenous leukemia, or myeloproliferative disorders.

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