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

RATIONALE: Monoclonal antibodies, such as alemtuzumab and 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 alemtuzumab together with rituximab may kill more cancer cells. PURPOSE: This phase II trial is studying the side effects and how well giving alemtuzumab together with rituximab works in treating patients with high-risk, early-stage chronic lymphocytic leukemia.

This phase I/II study is designed to determine the safety and tolerability of APO866 for the treatment of refractory B-CLL not amenable to aHSCT. APO866 has shown to induce growth inhibition in cultures of a wide variety of human hematological malignant cells as well as in models with subcutaneously implanted human tumors. APO866 was considered to be safe and well-tolerated in a phase I study that treated 24 patients with advanced cancer. APO866 is administered by intravenous infusion continuously for 96 hours and is repeated every 4 weeks. In this study patients will receive only one cycle of treatment and the study endpoints will be evaluated 4 weeks after the start of infusion. Patients will be followed up for 12 weeks for safety.

RATIONALE: Biological therapies, such as agatolimod sodium, may stimulate the immune system in different ways and stop cancer cells from growing. 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. Radiolabeled monoclonal antibodies, such as yttrium Y 90 ibritumomab tiuxetan, can find cancer cells and carry cancer-killing substances to them without harming normal cells. Giving agatolimod sodium together with rituximab and yttrium Y 90 ibritumomab tiuxetan may kill more cancer cells. PURPOSE: This phase I/II trial is studying the side effects and best dose of agatolimod sodium when given together with rituximab and yttrium Y 90 ibritumomab tiuxetan and to see how well it works in treating patients with recurrent or refractory non-Hodgkin lymphoma.

The main aim of this study is to test the safety of acadesine in patients with B-CLL and see what effects it has on patients and their leukaemia. The study also aims to examine the way acadesine is processed by the body. The study will look at the effects of acadesine in the body and the concentration of the drug and its main by-product (ZMP) in the blood to determine the dose and the frequency of dosing that is likely to be the most effective.

This randomized phase II trial studies how well fludarabine (fludarabine phosphate) and rituximab with or without lenalidomide or cyclophosphamide work in treating patients with symptomatic chronic lymphocytic leukemia. Drugs used in chemotherapy, such as fludarabine phosphate and cyclophosphamide, work in different ways to stop the growth of cancer cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. Monoclonal antibodies, such as rituximab, may block cancer growth in different ways by targeting certain cells. Lenalidomide may stimulate the immune system in different ways and stop cancer cells from growing. Giving fludarabine phosphate and rituximab together with lenalidomide or cyclophosphamide may be an effective treatment for chronic lymphocytic leukemia.

The purpose of this study is to assess the safety and tolerability of escalating doses of SNS-032, given in 3 weekly administrations per cycle and to identify a recommended Phase 2 dose.

The purpose of this research study is to assess the safety and immune activity of a vaccine made from the participant's own cancer cells, when administered after a reduced intensity transplant. In recent years, researchers at Dana-Farber Cancer Institute have discovered that vaccines made from a patients's own cancer cells, that have been engineered in the laboratory to produce a protein called GM-CSF, can be effective in stimulating a powerful immune response specific to that cancer.

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, 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 cyclophosphamide and rituximab may kill more cancer cells. PURPOSE: This phase II trial is studying the side effects and how well giving pentostatin together with cyclophosphamide and rituximab works in treating patients with previously untreated chronic lymphocytic leukemia.

This single arm study will assess the safety and effect on response rate of a combination of rituximab and chlorambucil in previously untreated participants with B-cell chronic lymphocytic leukemia. Participants will receive 6 monthly cycles of combination treatment, followed by up to 6 cycles of chlorambucil alone. Rituximab will be administered on Day 1 of each cycle, at a dose of 375 milligrams per square meter (mg/m^2) intravenously (IV) in Cycle 1, and 500 mg/m^2 in subsequent cycles, and chlorambucil will be administered on Days 1-7 of each cycle at a dose of 10 mg/m^2/day per oral (PO).

The purpose of this study is to determine if a subcutaneous (SC) dosing schedule of veltuzumab can be established in NHL or CLL patients and to confirm the safety and efficacy of veltuzumab that was previously established when administered intravenously.
