Active clinical trials for "Leukemia, Lymphoid"

RATIONALE: Drugs used in chemotherapy, such as pentostatin and 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 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. It is not yet known whether giving pentostatin and cyclophosphamide together with rituximab is more effective with or without bevacizumab in treating patients with B-cell chronic lymphocytic leukemia or small lymphocytic lymphoma. PURPOSE: This randomized phase II trial is studying the side effects of giving pentostatin and cyclophosphamide together with rituximab with or without bevacizumab and to see how well it works in treating patients with B-cell chronic lymphocytic leukemia or small lymphocytic lymphoma.

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.

The primary objective of this study (TOTXVI) is to compare the clinical benefit, the pharmacokinetics, and the pharmacodynamics of polyethylene glycol-conjugated (PEG) asparaginase given in higher dose (HD PEG) versus those of PEG-asparaginase given in conventional dose (CD PEG) during the continuation phase. This study has several secondary objectives: Therapeutic Objectives: To estimate the event-free survival and overall survival of children with ALL who are treated with risk-directed therapy. To study whether intensifying induction, including fractionated cyclophosphamide and thioguanine, in patients with day 15 MRD > 5%, will result in improved leukemia cytoreduction in this subgroup compared to TOTXV. To assess whether intensification of central nervous system (CNS)-directed intrathecal and systemic chemotherapy will improve outcome in patients at high risk of CNS relapse. Exploratory Pharmacologic Objectives: To identify pharmacogenetic, pharmacokinetic and pharmacodynamic predictors for treatment-related outcomes in the context of the systemic therapy used in the protocol. To compare the pharmacokinetics and pharmacodynamics of PEG-asparaginase given in higher dose (3,500 or 3,000 units/m2) versus those of PEG-asparaginase given in conventional dose (2,500 units/m2) in the continuation phase. Exploratory Biologic Objectives: To determine the prognostic value of levels of minimal residual disease in peripheral blood at day 8 of remission induction. To validate new markers and methods for MRD detection. To genotype natural killer (NK) cell receptors and measure their expressions at diagnosis and before reinduction, and to associate these features with treatment outcome. To identify new prognostic factors by applying new technologies to study patient material (e.g., stored plasma, serum, cerebrospinal fluid, and normal and leukemic cells). Exploratory Neuroimaging Objectives: To use quantitative MR measures (Diffusion Tensor Imaging and high resolution volumetric imaging) to assess differences in myelin and cortical thickness development in patients treated for ALL relative to healthy controls matched for age and gender. To assess the impact of folate pathway genetic polymorphisms on myelin and cortical thickness development and neurocognitive performance. To assess the impact of frontal-parietal lobe myelin and cortical thickness development on neurocognitive performance in attention, working memory, fluency, visual-spatial reasoning and processing speed.

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 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.

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