Filter by:This phase II trial is studying how well fludarabine phosphate and total-body irradiation followed by donor peripheral blood stem cell transplant work in treating patients with acute lymphoblastic leukemia or chronic myelogenous leukemia that has responded to previous treatment with imatinib mesylate, dasatinib, or nilotinib. Giving low doses of chemotherapy, such as fludarabine phosphate, and total-body irradiation (TBI) 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 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 mycophenolate mofetil and cyclosporine after the transplant may stop this from happening.
RATIONALE: Light-emitting diode (LED) therapy may be able to prevent mucositis of the mouth. PURPOSE: Randomized phase II trial to determine the effectiveness of LED therapy in preventing mucositis of the mouth in children who are receiving chemotherapy with or without radiation therapy before donor bone marrow transplantation.
The purposes of this study are to determine a maximum tolerated dose and to evaluate the safety and efficacy of CP-461 in patients with Chronic Lymphocytic Leukemia.
The purpose of this study is to determine the safety and tolerability of an oral Farnesyl Protein Transferase Inhibitor (SCH 66336) as a single agent in patients with Advanced Myelodysplastic Syndrome, Acute Myelogenous Leukemia, Chronic Myelogenous Leukemia in Blast Crisis, or Acute Lymphoblastic Leukemia.
RATIONALE: Cyclosporine may improve low blood counts caused by hematologic cancer. PURPOSE: Phase II trial to study the effectiveness of cyclosporine in treating patients who have low blood counts caused by hematologic cancer.
The reason for doing this study is to determine whether a new method of blood stem cell transplant (also known as bone marrow transplant) is able to treat acute lymphocytic leukemia. Blood stem cells are the "seed cells" necessary to make all blood cells. This new method of transplant uses a combination of low dose radiation and chemotherapy that may be less toxic and cause less harm than a conventional transplant. This lower dose transplant is called a "nonmyeloablative transplant". Researchers want to see if using less radiation and less chemotherapy combined with new immune suppressing drugs after the transplant will help a stem cell transplant to work. Researchers hope that this treatment will cure acute lymphocytic leukemia with fewer side effects. Researchers are hoping to see a mixture of recipient and donor blood cells after transplant. This mixture of donor and recipient blood cells is called "mixed chimerism". Researchers hope that donor cells will attack and eliminate the leukemia. This is called the "graft-versus-leukemia" effect. In addition, after the transplant, white blood cells from the donor may be given to enhance or "boost" the graft-versus-leukemia effect, and hopefully remove all remaining cancer cells. This study is being done because at the present time blood stem cell transplantation (or bone marrow transplantation) is the only known curative therapy for acute lymphocytic leukemia. Because of age or underlying health status acute lymphocytic leukemia patients have a higher likelihood of experiencing severe harm from a conventional blood stem cell transplant. Researchers are doing this study to see if this new nonmyeloablative method of low dose radiation and low dose chemotherapy given before transplant and immune suppressive drugs after transplant will help make the transplant safer and also cure acute lymphocytic leukemia
RATIONALE: Thalidomide may be an effective treatment for anemia caused by myelodysplastic syndrome. PURPOSE: Randomized phase II trial to study the effectiveness of thalidomide in treating anemia in patients who have myelodysplastic syndrome.
This phase II trial is studying imatinib mesylate to see how well it works in treating patients with chronic myelogenous leukemia. Imatinib mesylate may stop the growth of cancer cells by blocking the enzymes necessary for cancer cell growth
RATIONALE: Drugs used in chemotherapy use different ways to stop cancer cells from dividing so they stop growing or die. PURPOSE: Phase I/II trial to study the effectiveness of homoharringtonine in treating patients who have refractory acute promyelocytic leukemia.
RATIONALE: Vaccines made from a person's white blood cells may make the body build an immune response to kill cancer cells. PURPOSE: Phase I trial to study the effectiveness of vaccine therapy in treating patients who have chronic myelogenous leukemia.
