Active clinical trials for "Leukemia, Lymphocytic, Chronic, B-Cell"

RATIONALE: Pentostatin may stop the growth of cancer cells by blocking some of the enzymes needed for cell growth. Drugs used in chemotherapy, such as cyclophosphamide and mitoxantrone, 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. Giving pentostatin together with combination chemotherapy and rituximab may kill more cancer cells. PURPOSE: This phase I/II trial is studying the side effects and best dose of mitoxantrone when given together with pentostatin, cyclophosphamide, and rituximab and to see how well it works in treating patients with chronic lymphocytic leukemia or other low-grade B-cell cancer.

RATIONALE: 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 find cancer cells and help kill them or carry cancer-killing substances to them. Colony-stimulating factors, such as GM-CSF, may increase the number of immune cells found in bone marrow or peripheral blood. Giving monoclonal antibody therapy together with GM-CSF may be an effective treatment for early-stage chronic lymphocytic leukemia. PURPOSE: This phase II trial is studying the side effects of giving rituximab and alemtuzumab together with GM-CSF and to see how well it works in treating patients with early-stage chronic lymphocytic leukemia.

RATIONALE: Drugs used in chemotherapy, such as fludarabine and cyclophosphamide, work in different ways to kill cancer cells or stop them from growing. Monoclonal antibodies, such as rituximab and alemtuzumab, can block cancer growth in different ways. Some find cancer cells and help kill them or carry cancer-killing substances to them. Others interfere with the ability of cancer cells to grow and spread. It is not yet known whether giving fludarabine and cyclophosphamide together with rituximab is more effective than giving fludarabine and cyclophosphamide together with alemtuzumab in treating B-cell chronic lymphocytic leukemia. PURPOSE: This randomized phase III trial is studying giving fludarabine together with cyclophosphamide and rituximab to see how well it works as first-line therapy compared with giving fludarabine together with cyclophosphamide and alemtuzumab in treating patients with B-cell chronic lymphocytic leukemia.

To determine if the rate of cytomegalovirus reactivation during treatment with alemtuzumab (Campath) is reduced by the use of valganciclovir prophylaxis.

This study will test different doses of anti-CD74 antibody in patients with NHL and/or CLL.

Oral clofarabine is related to two intravenous chemotherapy drugs used for this disease and works in two different ways. It affects the development of new cancer cells by blocking two enzymes that cancer cells need to reproduce. When these enzymes are blocked, the cancer call can no longer prepare the DNA needed to make new cells. Clofarabine also encourages existing cancer cells to die by disturbing components within the cancer cell. This causes the release of a substance that is fatal to the cell. This trial studies the efficacy of oral clofarabine in the treatment of relapsed non-Hodgkin lymphomas.

The purpose of this study is to determine the dose that can be safely given to see what effect it may have on your cancer and to determine how the drug is distributed in the body.

Objectives: To evaluate disease free survival after Campath 1H-based in vivo T-cell depletion and non-myelo-ablative ablative stem cell transplantation in patients with hematologic malignancies. To evaluate the incidence and severity of acute and chronic GVHD after Campath 1H-based in vivo T-cell depletion, in patients with hematologic malignancies undergoing non-myelo-ablative stem cell transplantation. To evaluate engraftment and chimerism after Campath 1H-based in vivo T-cell depletion and non-myelo-ablative ablative stem cell transplantation in patients with hematologic malignancies.

The aim of this study is to determine the maximal tolerated dose level of lenalidomide combined with fludarabine/rituximab in the therapy of patients with previously untreated CD20-positive chronic lymphocytic leukemia. Following a dose escalation phase lenalidomide will be given at the pre-determined maximum tolerated dose in combination with rituximab to further determine the efficacy and tolerability of this regimen.

Primary Objectives To determine the safety and maximum tolerated dose (MTD) of Adenovirus-CD154 (Ad-ISF35) when it is injected directly into the lymph nodes of patients with CLL or SLL. Secondary Objectives To determine and monitor clinical and biological responses in patients treated with injections of Ad-ISF35. To determine how ISF35 works in CLL/SLL patients' cells.
