Active clinical trials for "Leukemia"

RATIONALE: Drugs used in chemotherapy, such as busulfan and fludarabine, work in different ways to stop the growth of cancer cells, either by killing the cells or by stopping them from dividing. Giving chemotherapy with a peripheral stem cell or bone marrow transplant may allow more chemotherapy to be given so that more cancer cells are killed. Sometimes the transplanted cells from a donor can make an immune response against the body's normal cells. Tacrolimus and methotrexate may stop this from happening. PURPOSE: This phase II trial is studying how well giving busulfan together with fludarabine before donor stem cell transplant works in treating patients with hematologic cancer.

The purpose of this study is to further assess the safety of dasatinib in imatinib intolerant or resistant patients with chronic phase chronic myeloid leukemia, advanced phase chronic myeloid leukemia or Philadelphia chromosome positive acute lymphoblastic leukemia. The efficacy of the drug in this kind of patients will also further be documented.

RATIONALE: Drugs used in chemotherapy, such as cyclophosphamide, work in different ways to stop the growth of cancer cells, either by killing the cells or by stopping them from dividing. Monoclonal antibodies, such as rituximab, can block cancer growth in different ways. Some block the ability of cancer cells to grow and spread. Others find cancer cells and help kill them or carry cancer-killing substances to them. Vaccines may help the body build an effective immune response to kill cancer cells. Giving cyclophosphamide and rituximab together with vaccine therapy may kill more cancer cells. PURPOSE: This randomized phase II trial is studying cyclophosphamide and rituximab followed by two different schedules of vaccine therapy to compare how well they work in treating patients with chronic lymphocytic leukemia.

The purpose of this study is to test the safety of a new investigational acute myeloblastic leukemia (AML) vaccine and see what effects (good and bad) it has on patients with advanced myelodysplasia or acute myelogenous leukemia.

Dasatinib and lenalidomide are both prescribed for use in patients with different cancers of the blood. This study is experimental because neither drug has been approved by the Food and Drug Administration for the treatment of chronic lymphocytic leukemia. There are few standard treatments when fludarabine is no longer effective in patients with CLL. Some patients have received additional combination therapy with fludarabine, Campath, bone marrow transplants or supportive care. Dasatinib and lenalidomide have been effective in high-risk CLL patients in other pilot mono therapy studies. The combination of dasatinib and lenalidomide has not been studied in humans before and this study is designed to test whether this combination is safe to use.

RATIONALE: Drugs used in chemotherapy, such as bendamustine, work in different ways to stop the growth of cancer cells, either by killing the cells or by stopping them from dividing. Monoclonal antibodies, such as rituximab, can block cancer cell growth in different ways. Some block the ability of cancer cells to grow and spread. Others find cancer cells and help kill them or carry cell-killing substances to them. Giving bendamustine together with rituximab may kill more cancer cells. PURPOSE: This phase II trial is studying the side effects of giving bendamustine together with rituximab and to see how well it works in treating patients with B-cell chronic lymphocytic leukemia that has not responded to previous treatment.

RATIONALE: Drugs used in chemotherapy, such as fludarabine phosphate, work in different ways to stop the growth of cancer cells, either by killing the cells or by stopping them from dividing. Monoclonal antibodies, such as rituximab and bevacizumab, can block cancer growth in different ways. Some block the ability of cancer cells to grow and spread. Others find cancer cells and help kill them or carry cancer-killing substances to them. Giving fludarabine phosphate together with rituximab and bevacizumab may kill more cancer cells. PURPOSE: This phase II trial is studying how well giving fludarabine phosphate together with rituximab and bevacizumab works in treating patients with B-cell chronic lymphocytic leukemia that has relapsed or not responded to treatment.

This is an open-label, multi-center study with 2 arms. The primary objective is to assess the response to treatment with rasburicase in 2 populations of adult and pediatric patients with lymphoma/leukemia/solid tumor malignancies, those previously treated with a uricolytic agent, and those not previously treated with a uricolytic agent at their first relapse or refractory disease.

Since there is no standard rescue therapy for refractory CLL or relapsed to the purine analogous, our target is to carry out a rescue therapy combining several chemotherapy agents (CHOP) adding the synergistic effect of Rituximab in order to act against tumour-like CLL forms, with assessable size lymph nodes. Afterwards, based in other studies, we shall study the role of Alemtuzumab as drug for consolidation or improvement of responses obtained with the initial therapy (CHOP-R), acting by "cleaning" from peripheral blood and bone marrow the CLL lymphocytes that may have had remain as residual after chemotherapy induction therapy. More precisely, the addition of Alemtuzumab as maintenance treatment would increase the complete responses with negative residual disease number and may prolong the duration of the response. For this, it is necessary to have not only an adequate and rigorous clinical follow-up but also biological, i.e. being able to analyze minimal residual disease by molecular biology techniques. This is the reason of writing this phase II clinical trial protocol.

RATIONALE: Monoclonal antibodies such as rituximab can locate tumor cells and either kill them or deliver tumor-killing substances to them without harming normal cells. Biological therapies such as interferon alfa-2b use different ways to stimulate the immune system and stop cancer cells from growing. PURPOSE: Phase II trial to study the effectiveness of rituximab or interferon alfa-2b in treating patients who have chronic lymphocytic leukemia or multiple myeloma in remission.
