Active clinical trials for "Leukemia, Lymphoid"

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.

The goal of this clinical research study is to learn if lenalidomide (Revlimid®) can help to control CLL in patients who have already received standard therapy. The safety of lenalidomide will also be studied.

The goal of this clinical research study is to learn if dasatinib can help to control Chronic Lymphocytic Leukemia (CLL). The safety of the drug will also be studied. Optional Procedures: You will be asked to have additional blood samples drawn. These samples will be used to see how the disease is responding to the drug.

This randomized phase III trial is studying low-dose vincristine to see how well it works compared with high-dose vincristine when given together with different combination chemotherapy regimens in treating young patients with intermediate-risk relapsed B-cell acute lymphoblastic leukemia. Drugs used in chemotherapy 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) and giving the drugs in different ways and different doses may kill more cancer cells..

RATIONALE: Giving chemotherapy drugs, such as fludarabine and cyclophosphamide, and total-body irradiation before a donor umbilical cord blood stem cell transplant helps stop the growth of cancer cells and prepares the patient's bone marrow for the stem 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. Sometimes the transplanted cells from a donor can make an immune response against the body's normal cells. Giving cyclosporine and mycophenolate mofetil may stop this from happening. PURPOSE: This phase II trial is studying how well giving fludarabine and cyclophosphamide together with total-body irradiation works in treating patients who are undergoing an umbilical cord blood transplant for hematologic cancer.

The primary objective of the trial is to estimate the activity of BMS-354825 (Dasatinib) in de novo adult Ph+ ALL patients in terms of hematological complete remission (HCR) rate.

Bone marrow stem cell transplants (otherwise called bone marrow transplants) from healthy donors are sometimes the only means of curing hematological malignant diseases such as acute and chronic leukemias, myelodysplastic syndrome, myeloproliferative diseases and lymphomas. Before transplant the patient receives chemotherapy and radiation treatment to reduce the malignancy to low levels and to prevent rejection of the transplant. The transplant restores the blood counts to normal and replaces the patients immunity with that of the donor. The donors immune cells increase the effect of the transplant by attacking remaining malignant cells. Donor immune cells (especially those called T lymphocytes) also attack healthy non-cancerous cells and tissues of the recipient causing "graft-versus-host-disease" (GVHD). Strong GVHD reactions occurring within weeks after the transplant can be life-threatening . In this study we remove most of the T lymphocytes from the transplant to minimize the risk of GVHD. However to improve immunity against residual malignant cells and boost immunity to infections, donor T cells (stored frozen at time of transplant) are given back around 90 days after the transplant when they have a reduced risk of causing serious GVHD. Any patient between 10 and 75 years of age with acute or chronic leukemia, myelodysplastic syndrome, myeloproliferative syndromes or lymphoma, who have a family member who is a suitable stem cell donor may be eligible for this study. Candidates are screened with a medical history and various tests and examinations.

RATIONALE: Drugs used in chemotherapy, such as cytarabine and clofarabine, 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 II trial is studying how well giving cytarabine together with clofarabine works in treating patients with relapsed or refractory acute lymphoblastic leukemia.

The purpose of this study is to determine whether HuMax-CD20 (ofatumumab) is effective in the treatment of patients failing both fludarabine and alemtuzumab.

This study aims to assess the short term efficacy of a combination immunochemotherapy in patients with relapsed B-cell chronic lymphatic leukemia.
