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

This randomized phase III trial studies how well graft-vs-host disease (GVHD) prophylaxis works in treating patients with hematologic malignancies undergoing unrelated donor peripheral blood stem cell transplant. Giving chemotherapy and total-body irradiation before a donor peripheral blood stem cell transplant (PBSCT) helps stop the growth of cancer cells. It may also stop the patient's immune system from rejecting the donor's 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 total-body irradiation (TBI) together with fludarabine phosphate (FLU), cyclosporine (CSP), mycophenolate mofetil (MMF), or sirolimus before transplant may stop this from happening.

RATIONALE: Carfilzomib may stop the growth of cancer cells by blocking some of the enzymes needed for cell growth. PURPOSE: This phase I trial is studying the side effects and the best dose of carfilzomib in treating patients with relapsed or refractory chronic lymphocytic leukemia(CLL),small lymphocytic lymphoma(SLL), or prolymphocytic leukemia (PLL).

This single arm, open-label study will assess the safety and efficacy of low dose fludarabine and cyclophosphamide in combination with standard dose MabThera/Rituxan (rituximab) as primary therapy in elderly patients (>/= 65 years) with chronic lymphocytic leukemia. Patients will receive six 28-day cycles of treatment with Mabthera/Rituxan (375 mg/m2 intravenously [iv] Day 0 of cycle 1, 500 mg/m2 iv Day 1 of cycles 2-6), fludarabine (12.5 mg/m2/d iv Days 1-3, cycles 1-6) and cyclophosphamide (150 mg/m2/d iv Days 1-3, cycles 1-6). Anticipated time on study treatment is 6 months, with a 30-month follow-up period.

Panobinostat may stop the growth of cancer cells by blocking some of the enzymes needed for cell growth. This phase II trial is studying how well panobinostat works in treating patients with relapsed or refractory non-Hodgkin lymphoma

RATIONALE: Monoclonal antibodies such as alemtuzumab can locate tumor cells and either kill them or deliver tumor-killing substances to them without harming normal cells. Peripheral stem cell transplantation may be able to replace immune cells that were destroyed by chemotherapy or radiation therapy. Combining monoclonal antibody therapy, chemotherapy, radiation therapy, and peripheral stem cell transplantation may kill more tumor cells. PURPOSE: Phase II trial to study the effectiveness of alemtuzumab plus peripheral stem cell transplantation in treating patients who have chronic lymphocytic leukemia.

RATIONALE: Drugs used in chemotherapy use different ways to stop cancer cells from dividing so they stop growing or die. Combining more than one drug may kill more cancer cells. PURPOSE: Phase I trial to study the effectiveness of bryostatin 1 plus fludarabine in treating patients who have chronic lymphocytic leukemia or relapsed, indolent non-Hodgkin's lymphoma.

The purpose of this research study is to test whether giving T-cells (type of white blood cell that are also known as immune cells) that have been specially processed in the laboratory will help chronic lymphocytic leukemia (CLL) patients' immune system return to normal faster after chemotherapy. This research study will also look into the ability of the lab to process the T-cells for infusion and the side effects of giving T-cells to patients with chronic lymphocytic leukemia (CLL).

This phase II trial studies autologous peripheral blood stem cell transplant followed by donor bone marrow transplant in treating patients with high-risk Hodgkin lymphoma, non-Hodgkin lymphoma, multiple myeloma, or chronic lymphocytic leukemia. Autologous stem cell transplantation uses the patient's stem cells and does not cause graft versus host disease (GVHD) and has a very low risk of death, while minimizing the number of cancer cells. Peripheral blood stem cell (PBSC) transplant uses stem cells from the patient or a donor and may be able to replace immune cells that were destroyed by chemotherapy. These donated stem cells may help destroy cancer cells. Bone marrow transplant known as a nonmyeloablative transplant uses stem cells from a haploidentical family donor. Autologous peripheral blood stem cell transplant followed by donor bone marrow transplant may work better in treating patients with high-risk Hodgkin lymphoma, non-Hodgkin lymphoma, multiple myeloma, or chronic lymphocytic leukemia.

This open-label, randomized, 3-arm study will evaluate the efficacy and safety of obinutuzumab (RO5072759) in combination with chlorambucil as compared to rituximab plus chlorambucil or chlorambucil alone in patients with previously untreated chronic lymphocytic leukemia (CLL). Patients will be randomized 2:2:1 to receive a maximum of six 28-day cycles of either RO5072759 (1000 mg intravenous (iv) infusion, on days 1, 8 and 15 of cycle 1 and day 1 of cycles 2-6) plus chlorambucil (0.5 mg/kg orally, days 1 and 15 of cycles 1-6), or rituximab (iv infusion day 1, 375 mg/m^2 cycle 1, 500 mg/m^2 cycles 2-6) plus chlorambucil, or chlorambucil alone. Anticipated time on study treatment is >6 months and follow-up for disease-progression and safety will be at least 5 years. In the US, this trial is sponsored/managed by Genentech.

This phase II trial studies how well lenalidomide and ofatumumab work in treating participants with previously treated chronic lymphocytic leukemia or small lymphocytic lymphoma. Drugs used in chemotherapy, such as lenalidomide, work in different ways to stop the growth of tumor cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. Monoclonal antibodies, such as ofatumumab, may interfere with the ability of tumor cells to grow and spread. Giving lenalidomide and ofatumumab may work better in treating participants with chronic lymphocytic leukemia or small lymphocytic lymphoma
