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

This phase I trial studies the side effects, best way to give, and the best dose of alvocidib when given together with fludarabine phosphate and rituximab in treating patients with previously untreated or relapsed lymphoproliferative disorders or mantle cell lymphoma. Monoclonal antibodies such as rituximab can locate cancer cells and either kill them or deliver cancer-killing substances to them without harming normal cells. Drugs used in chemotherapy such as alvocidib and fludarabine use different ways to stop cancer cells from dividing so they stop growing or die. Combining monoclonal antibody therapy with chemotherapy may kill more cancer cells.

RATIONALE: Monoclonal antibodies can locate tumor cells and either kill them or deliver tumor-killing substances to them without harming normal cells. PURPOSE: Phase I trial to study the effectiveness of monoclonal antibody therapy in treating patients who have relapsed or refractory chronic lymphocytic leukemia or small lymphocytic lymphoma.

This clinical trial studies how well giving fludarabine phosphate together with total-body irradiation (TBI) before donor peripheral blood stem cell transplant works in treating patients with chronic lymphocytic leukemia or small lymphocytic leukemia. Giving low doses of chemotherapy, such as fludarabine phosphate, and TBI before a donor peripheral blood stem cell transplant helps stop the growth of cancer cells. Giving chemotherapy before or after peripheral blood stem cell transplant also stops the patient's immune system from rejecting the donor's stem cells. The donated stem cells may replace the patient's immune cells and help destroy any remaining cancer cells (graft-versus-tumor effect). Sometimes the transplanted cells from a donor can also make an immune response against the body's normal cells. Giving cyclosporine and mycophenolate mofetil before and after the transplant may stop this from happening.

The purpose of this study is to determine whether a reduced intensity conditioning regimen for stem cell transplant with donor cells will allow the donor cells to be effective without causing health problems.

The goal of this clinical research study is to learn if giving CAMPATH-1H first as an injection into a vein, then as an injection under the skin can shrink or slow the growth of the disease in patients with chronic lymphocytic leukemia (CLL) who have already received standard therapy. Another goal is to learn if the side effects related to CAMPATH-1H treatment are less severe by giving the drug first as an injection into a vein then as an injection under the skin.

RATIONALE: Biological therapies such as lenalidomide use different ways to stimulate the immune system and stop cancer cells from growing. Monoclonal antibodies such as rituximab can locate cancer cells and either kill them or deliver cancer-killing substances to them without harming normal cells. Combining lenalidomide with rituximab may kill more cancer cells. PURPOSE: This phase II trial is studying the how well giving lenalidomide with or without rituximab works in treating patients with relapsed or refractory chronic lymphocytic leukemia.

This phase II trial studies pentostatin and donor lymphocyte infusion in preventing graft rejection in patients who have undergone donor stem cell transplant. Giving pentostatin and an infusion of the donor's T cells (donor lymphocyte infusion) after a donor stem cell transplant may stop the patient's immune system from rejecting the donor's stem cells. The donated stem cells may replace the patient's immune cells and help destroy any remaining cancer cells (graft-versus-tumor effect). Sometimes the transplanted cells from a donor can also make an immune response against the body's normal cells. Giving pentostatin before donor lymphocyte infusion may stop this from happening.

This is a Phase 3, prospective, multicenter, open-label, randomized, controlled study to evaluate and compare the efficacy and safety of fludarabine plus alemtuzumab versus fludarabine alone as second-line therapy for patients with relapsed or refractory B-cell chronic lymphocytic leukemia (B-CLL). Patients who meet all eligibility criteria and sign the informed consent document may be entered on the study.

This phase I trial is studying the side effects and best dose of 17-DMAG in treating patients with metastatic or unresectable solid tumors or lymphomas. Drugs used in chemotherapy, such as 17-DMAG, work in different ways to stop cancer cells from dividing so they stop growing or die

To determine the safety and efficacy of elsamitrucin in patients with relapsed or refractory non-Hodgkin's lymphoma (NHL). To determine if elsamitrucin is efficacious in a particular pathologic NHL subtype(s).
