Active clinical trials for "Leukemia"

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: Drugs used in chemotherapy, such as cladribine, use different ways to stop cancer cells from dividing so they stop growing or die. Monoclonal antibodies, such as rituximab, can locate cancer cells and either kill them or deliver cancer-killing substances to them without harming normal cells. Combining cladribine with rituximab may kill more cancer cells. PURPOSE: This phase II trial is studying how well giving cladribine and rituximab as remission induction therapy together with rituximab and stem cell mobilization in treating patients with chronic lymphocytic leukemia.

RATIONALE: Biological therapies, such as denileukin diftitox, may interfere with the growth of cancer cells and slow the growth of chronic lymphocytic leukemia. PURPOSE: This phase II trial is studying how well denileukin diftitox works in treating patients with fludarabine-refractory B-cell chronic lymphocytic leukemia.

The principal goal of this clinical trial is to assess the ability of cenersen sodium (EL625) to improve cancer responsiveness to the established AML therapeutic agent Idarubicin used alone or in combination with Cytarabine (Ara-C). Cenersen sodium is a drug that is designed to block the effects of a protein called p53. Laboratory evidence shows that blocking p53 will make many types of cancer, including acute myelogenous leukemia (AML), more sensitive to a variety of established cancer therapeutics while making normal tissues more resistant to the toxic effects of these agents.

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 purpose of this study is to assess the toxicity and the rate of complete and overall response using fludarabine, rituximab, and alemtuzumab to treat patients with B-chronic lymphocytic leukemia or small lymphocytic leukemia who have received previous treatment.

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).

This phase II trial is studying how well giving fludarabine together with rituximab followed by alemtuzumab works in treating patients with chronic lymphocytic leukemia. Monoclonal antibodies, such as rituximab and alemtuzumab, can block cancer growth in different ways. Some block the ability of cancer cells to grow and spread. Others can find cancer cells and help kill them or carry cancer-killing substances to them. Drugs used in chemotherapy, such as fludarabine, work in different ways to stop the growth of cancer cells, either by killing the cells or by stopping them from dividing. Giving fludarabine together with rituximab followed by alemtuzumab may kill more cancer cells.

Phase I trial to study the effectiveness of combining MS-275 with isotretinoin in treating patients who have metastatic or advanced solid tumors or lymphomas. MS-275 may stop the growth of cancer cells by blocking the enzymes necessary for their growth. Isotretinoin may help cancer cells develop into normal cells. MS-275 may increase the effectiveness of isotretinoin by making cancer cells more sensitive to the drug. MS-275 and isotretinoin may also stop the growth of solid tumors or lymphomas by stopping blood flow to the cancer. Combining MS-275 with isotretinoin may kill more cancer cells

Tipifarnib may stop the growth of cancer cells by blocking some of the enzymes needed for cell growth. This phase I trial is studying the side effects and best dose of tipifarnib in treating patients with relapsed or refractory acute myeloid leukemia
