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

The purpose of this study is to provide treatment for patients who have chronic lymphocytic leukemia (CLL), and to compare the use of rituximab added to fludarabine+cyclophosphamide (FC) with FC alone, to determine if rituximab lengthens the time a patient remains free of leukemia symptoms.

The goal of this clinical research study is to find the highest safe dose of Mylotarg that can be combined with chemotherapy in patients receiving allogeneic bone marrow transplantation. Researchers will study the effects of this treatment combination on patients with high-risk acute leukemia, chronic myelogenous leukemia, or myelodysplastic syndrome. Primary Objective: 1. To determine the safety and maximum tolerated dose of Mylotarg as part of a reduced-intensity preparative regimen patients undergoing related, mismatched-related or matched unrelated donor transplantation. Secondary Objectives: To evaluate response rates, engraftment kinetics and degree of chimerism achievable with this strategy. To evaluate the incidence and severity of GVHD in this population To evaluate disease-free and overall survival and relapse rates.

To evaluate the role of high dose therapy and autologous or allogeneic hematopoietic cell transplantation for the treatment of chronic lymphocytic leukemia.

This is a phase I/II study of the combination of etanercept and rituximab in patients with chronic lymphocytic leukemia (CLL) and small lymphocytic lymphoma (SLL). This combination is proposed to improve the efficacy and diminish the toxicity of this the

Monoclonal antibodies, such as yttrium Y 90 ibritumomab tiuxetan, can block find cancer cells and either kill them or carry cancer-killing substances to them without harming normal cells. Giving monoclonal antibodies, low doses of chemotherapy, such as fludarabine phosphate, and low dose total-body radiation therapy before a donor peripheral stem cell transplant helps stop the growth of cancer cells and 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 or mycophenolate mofetil after the transplant may stop this from happening

Primary Objectives: To document the efficacy of treatment with autologous lymphoma-derived HSPPC-96 of selected patients with indolent lymphoma. The efficacy endpoints are: the rate of complete and partial responses the time to progression. Secondary Objectives: To evaluate the safety and tolerability of autologous tumor-derived heat-shock protein peptide complex (HSPPC-96) administered intradermally once weekly for four consecutive weeks, followed by HSPPC-96 administered once every two weeks. To evaluate the feasibility of autologous HSPPC-96 preparation from lymphoma specimens. To assess approximately the composition of the tissue source of the autologous HSPPC-96 for each patient. To study the effect of autologous lymphoma-derived HSPPC-96 vaccine therapy on the expression of Fas ligand and TRAIL death proteins in peripheral blood lymphocytes of patients with indolent lymphoma.

This study will evaluate the effectiveness of an experimental drug called LMB-2 for treating chronic lymphocytic leukemia (CLL) in patients who have a protein called cluster of differentiation 25 (CD25) on their cancer cells. LMB-2 is a recombinant immunotoxin. It is made up of two parts: a genetically engineered monoclonal antibody that binds to cancer cells with CD25 on their surface, and a toxin produced by bacteria that kills the cancer cells to which it binds. LMB-2 has killed CD 25-containing cells in laboratory experiments and has caused tumors in mice to shrink. Preliminary studies in humans have shown some effectiveness in shrinking tumors in patients with various types of lymph and blood cancers. Patients 18 years of age and older with CLL who have CD25 receptor proteins on their cancer cells and whose disease has progressed within 2 years of treatment with fludarabine may be eligible for this study. Candidates are screened with a medical history and physical examination, blood and urine tests, electrocardiogram (EKG), echocardiogram, chest x-ray, computed tomography (CT) scans of the chest, abdomen and pelvis, and a bone marrow biopsy. Participants receive up to six cycles of LMB-2 therapy. Each 28-day cycle consists of 30-minute infusions of LMB-2 on cycle days 1, 3, and 5. The drug is infused through an intravenous (IV) catheter (plastic tube placed in a vein) or a central venous line-an IV tube placed in a large vein in the neck or chest that leads to the heart. Patients are admitted to the National Institutes of Health (NIH) Clinical Center for the first treatment cycle. If the infusion is well tolerated, subsequent cycles may be given on an outpatient basis. In addition to drug therapy, patients undergo the following procedures: Blood draws: Blood is drawn before, during, and after each LMB-2 infusion to measure blood levels of the drug, evaluate its effects on the cancer cells, and monitor side effects. Blood tests are also done before and during each cycle to determine how the immune system is interacting with the drug. Disease evaluations: Patients undergo a physical examination, blood tests, chest x-ray, and EKG before each treatment cycle and at follow-up visits. With the patient's permission, CT scans, echocardiogram, and bone marrow biopsies may be repeated before some treatment cycles if these tests prove useful in evaluating the disease response to LMB-2. Patients may receive up to six cycles of LMB-2 as long as their cancer does not worsen and they do not develop serious side effects. At the end of the treatment cycles, patients will have blood tests done weekly by their local physician, and the results will be sent to the NCI study investigators.

This study is for patients that have chronic lymphocytic leukemia (CLL). This research study aims to determine the safety and dosage of special cells that may make the patients own immune system fight the cancer. To do this, we will put a special gene into cancer cells that have been taken from the patients body. This will be done in the laboratory. This gene will make the cells produce interleukin 2 (IL-2), which is a natural substance that may help the immune system kill cancer cells. Additionally, we will stimulate the cancer cells with another natural protein called CD40 ligand (CD40L), which experiments in animal and human cells in vitro demonstrated can help IL-2 perform better. Some of these cells will then be put back into the patient's body. Studies of cancers in animals and in cancer cells that are grown in laboratories suggest that combining substances like IL-2 and CD40L helps the body kill cancer cells. An experimental treatment similar to this has already been used in children and similar experimental treatments are being used in adults with other cancers.

The goal of this clinical research study is to learn if giving CAMPATH-1H with rituximab can shrink or slow the growth of the disease in patients with chronic lymphoid disorders that have either not responded or whose disease has returned after treatment with standard therapies.

This phase I trial is studying the side effects and best dose of bortezomib when given together with fludarabine with or without rituximab in treating patients with relapsed or refractory indolent non-Hodgkin's lymphoma or chronic lymphocytic leukemia. Bortezomib may stop the growth of cancer cells by blocking the enzymes necessary for cancer cell growth. Drugs used in chemotherapy, such as fludarabine, work in different ways to stop cancer cells from dividing so they stop growing or die. 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 bortezomib together with fludarabine with or without rituximab may kill more cancer cells.
