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

RATIONALE: Giving chemotherapy before a donor bone marrow transplant helps stop the growth of cancer cells. It also helps stop the patient's immune system from rejecting the donor's stem cells. Also, monoclonal antibodies, such as alemtuzumab, can find cancer cells and either kill them or deliver cancer-killing substances to them without harming normal 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 methotrexate, cyclosporine and mycophenolate mofetil after the transplant may stop this from happening. Once the donated stem cells begin working, the patient's immune system may see the remaining cancer cells as not belonging in the patient's body and destroy them (called graft-versus-tumor effect). Giving an infusion of the donor's white blood cells (donor lymphocyte infusion) may boost this effect. PURPOSE: This phase I/II trial is studying the side effects of giving fludarabine together with cyclophosphamide and to see how well they work in treating patients who are undergoing donor stem cell transplant for B-cell chronic lymphocytic leukemia or Waldenström's macroglobulinemia.

This phase II trial studies how well giving ofatumumab together with pentostatin and cyclophosphamide works in treating patients with untreated chronic lymphocytic leukemia or small lymphocytic lymphoma. Monoclonal antibodies, such as ofatumumab, can block the ability of cancer cells to grow and spread. 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, by stopping them from dividing, or by stopping them from spreading. Giving ofatumumab together with pentostatin and cyclophosphamide may be a better way to block cancer growth.

This phase I trial studies the side effects and best dose of giving bortezomib and romidepsin together in treating patients with chronic lymphocytic leukemia (CLL), small lymphocytic lymphoma (SLL), indolent B-cell lymphoma, peripheral T-cell lymphoma (PTCL) or cutaneous T-cell lymphoma (CTCL). Bortezomib and romidepsin 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 dasatinib works in treating patients with unresectable or metastatic squamous cell skin cancer or RAI Stage 0-I chronic lymphocytic leukemia. Dasatinib may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth.

Primary Objective: 1. Evaluate the ability of Cyclophosphamide, Fludarabine, Alemtuzumab, and Rituximab (CFAR) to increase the proportion of patients with <5% CD5/CD19+ cells in bone marrow to 66% following 3 courses of treatment without significantly increasing the incidence of pneumonia or sepsis compared to a historic group of patients treated with the combination fludarabine, cyclophosphamide, and rituximab (FCR). Second Objectives: Assess complete remission (CR), nodular partial remission (nPR), and partial remission (PR) rates (overall response) in high-risk, previously untreated patients with CLL treated with CFAR. Evaluate molecular remission in bone marrow by polymerase chain reaction (PCR) for the clonal immunoglobulin heavy chain variable gene in responders treated with CFAR. Assess immune parameters including blood T cell counts and subset distribution and serum immunoglobulin levels pretreatment, during treatment, and post-treatment in patients treated with CFAR.

Primary Objective: To assess the activity of lenalidomide in patients with previously untreated chronic lymphocytic leukemia (CLL) age 65 and older. Secondary Objective: To assess the tolerability of lenalidomide in patients with untreated CLL age 65 and older

RATIONALE: Giving chemotherapy, such as cyclophosphamide and busulfan, and total-body irradiation before a donor stem cell transplant helps stop the growth of cancer cells. It also stops the patient's immune system from rejecting the donor's stem cells. The donated stem cells from bone marrow or umbilical cord blood 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 methotrexate and cyclosporine after transplant may stop this from happening. PURPOSE: This phase II trial is studying how well a donor stem cell transplant works in treating patients with previously treated lymphoma, multiple myeloma, or chronic lymphocytic leukemia.

The purpose of this study is to evaluate the safety and tolerability of TRU-016 in patients with previously treated chronic lymphocytic leukemia, and to obtain an estimate of clinical activity in patients with CLL and non-Hodgkin's lymphoma.

This phase I/II trial is studying the side effects and best dose of vorinostat when given together with rituximab, ifosfamide, carboplatin, and etoposide and to see how well they work in treating patients with relapsed or refractory lymphoma or previously untreated T-cell non-Hodgkin lymphoma or mantle cell lymphoma. Vorinostat may stop the growth of cancer cells by blocking some of the enzymes needed for cell growth. 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. Drugs used in chemotherapy, such as ifosfamide, carboplatin, and etoposide, work in different ways to stop the growth of cancer cells, either by killing the cells or by stopping them from dividing. Giving vorinostat together with rituximab and combination chemotherapy may kill more cancer cells

The purpose of the study is to determine whether it is possible to improve the immune response rate to 'flu vaccination in patients with chronic lymphocytic leukaemia (CLL). Annual flu vaccination is recommended for all patients with CLL because they are known to be susceptible to infections and particularly to chest infections that may occur as a complication of influenza. Protection against 'flu depends on patients having a high level of antibodies against the 'flu virus. Vaccination works by stimulating the immune system and thus boosting the levels of these protective antibodies. CLL patients have weakened immune systems due to the leukaemia itself but also following chemotherapy. The exact cause of these immune defects is not known. However, CLL patients typically have low antibody levels and their immune cells may not work normally. Unfortunately, studies have shown that patients with CLL are not very good at making antibodies to 'flu vaccination and as a result protection against flu is not very reliable. Recent studies have shown that only 15-20 % of CLL patients will achieve a protective antibody level. Recently a new type of medical cream has been introduced to treat certain skin conditions. Its name is Imiquimod and it is licensed to treat viral warts in the genital area and a type of skin cancer called basal cell carcinoma. It works by increasing the immune response in the skin. Animal studies have shown that as well as increasing immunity against viruses and cancers, it increases responses to vaccination when applied at the site of vaccination. In this study we propose to test whether this new medicine can improve the response to the 'flu jab.
