Active clinical trials for "Lymphoma, B-Cell"

Background: Burkitt lymphoma/leukemia (BL) is highly treatable, but most of the standard therapies require multiple doses of intensive chemotherapy that may require long hospital stays and frequently have severe side effects. In addition, BL is a fairly common type of cancer in patients who also have human immunodeficiency virus (HIV), but treatment outcomes are poor because standard treatments do not work very well in HIV-positive patients and the more intense treatment regimens are highly toxic. New approaches are needed that expand the ways to treat BL with the same efficiency but with reduced side effects. Etoposide, prednisone, vincristine, cyclophosphamide, doxorubicin, and rituximab (DA-EPOCH-R) is a standard chemotherapy treatment that consists of the drugs etoposide, prednisone, vincristine, cyclophosphamide, doxorubicin, and rituximab. It may be able to treat BL with similar effectiveness but with fewer side effects. Researchers are interested in confirming the results of previous studies that investigated the effectiveness of DA-EPOCH-R in treating BL. Objectives: - To determine the safety and effectiveness of DA-EPOCH-R in treating Burkitt lymphoma. Eligibility: - Individuals at least 18 years of age who have been diagnosed with Burkitt lymphoma and have not had any prior chemotherapy treatments. Design: Individuals will have a series of blood and other tests to determine their suitability for participating in the study. Eligible participants will be divided into high-risk and low-risk groups based on their disease prognosis and the possibility that the BL may or already has spread into the central nervous system. Participants will receive intravenous infusion of the six chemotherapy drugs in DA-EPOCH-R in 21-day treatment cycles. The exact doses will be adjusted depending on participants white blood cell counts and other tests. High-risk participants will receive six cycles of DA-EPOCH-R. To treat BL that may have entered the central nervous system, high-risk participants will also receive infusions of other chemotherapy drugs into their spinal fluid. Low-risk participants will receive up to six cycles of DA-EPOCH-R, with an additional dose of rituximab during each cycle. Frequent blood and urine tests will be performed during treatment, as well as body imaging scans and other tests of cancer progression as directed by the study doctors. Participants will receive additional medicines to help prevent possible adverse side effects of DA-EPOCH-R. Participants who respond successfully to the treatment will be asked to return for follow-up exams every 3 months for the first 18 months, then every year for the next 3 years. Participants who do not respond successfully to the treatment will be given the opportunity to participate in additional research and treatment protocols, if any are available.

RATIONALE: Giving high doses of chemotherapy drugs, such as busulfan and cyclophosphamide, before a donor bone marrow transplant 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 cyclosporine, methylprednisolone, and methotrexate after transplant may stop this from happening. PURPOSE: This clinical trial studies high-dose busulfan and high-dose cyclophosphamide followed by donor bone marrow transplant in treating patients with leukemia, myelodysplastic syndrome, multiple myeloma, or recurrent Hodgkin or Non-Hodgkin lymphoma.

This is a multicenter open-label uncontrolled phase II study. There are no previous clinical data to estimate the expected response rate of everolimus in MALT lymphomas and in the other less common MZLs (i.e. nodal and splenic) refractory or relapsing after at least 1 prior systemic treatment (chemotherapy or immunotherapy). The primary objective of this study is to define the antitumor activity, in term of overall response rate (ORR), as sum of complete remissions (CR) and partial remissions (PR) of everolimus in relapsed or refractory marginal zone B-cell lymphomas. The secondary objectives of this study are to assess safety, as acute or long-term toxicity, response duration (RD) (time to relapse or progression) in responders and progression-free survival (PFS) (time to disease progression or death from any cause) in all patients.

The purpose of this study is to determine the long-term safety of a fixed-dose, daily regimen of PCI-32765 PO in subjects with B cell lymphoma or chronic lymphocytic leukemia/small lymphocytic leukemia (CLL/SLL).

The purpose of this study is to compare lenalidomide to a control drug and see which one delays Diffuse Large B-Cell Lymphoma (DLBCL) disease progression longer.

This study is designed as a phase III, randomized, double-blind, placebo-controlled trial to explore the effect of maintenance therapy with lenalidomide versus placebo on progression-free survival (PFS) in patients treated with R-CHOP responding to induction therapy For the primary efficacy variable, PFS, an improvement in median PFS from 38.6 months for Treatment Arm B to 54 months for Treatment Arm A (corresponding to a 2-year PFS of 65% vs 73.6%), is considered clinically relevant.

RATIONALE: 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 cyclophosphamide, vincristine sulfate, prednisone, and liposome-encapsulated doxorubicin citrate, work in different ways to stop the growth of cancer cells, either by killing the cells or by stopping them from dividing. It is not yet known whether rituximab and combination chemotherapy are more effective when given together with or without liposome-encapsulated doxorubicin citrate in treating older patients with diffuse large B-cell non-Hodgkin lymphoma. PURPOSE: This randomized phase II trial is studying the side effects of giving rituximab together with cyclophosphamide, vincristine sulfate, and prednisone with or without liposome-encapsulated doxorubicin citrate and to see how well it works in treating older patients with stage II, stage III, or stage IV diffuse large B-cell non-Hodgkin lymphoma.

Everolimus is an oral mTOR inhibitor with demonstrated preliminary efficacy and safety in diffuse large B-cell lymphoma (DLBCL) in both preclinical and clinical studies. The purpose of this research study is to determine whether Everolimus plus rituximab is safe and effective in participants with relapsed or refractory DLBCL. Everolimus is an investigational drug that works by blocking a special protein that helps cancer cells grow. The safety and effectiveness of Everolimus in the treatment of DLBCL has not yet been fully determined and is still investigational. The other drug in this study, rituximab, is approved by the US Food and Drug Administration (FDA) for use in patients who have diffuse large B-cell lymphoma and certain other types of non-Hodgkin lymphoma. Rituximab is a drug that destroys both normal and cancerous B-cells.

The purpose of this study is to evaluate the safety, tolerability, and efficacy of vorinostat (MK-0683) in participants with relapsed and/or refractory follicular lymphoma. The exploratory purpose of this study is to evaluate efficacy of MK-0683 in participants with relapsed/refractory non-FL indolent B-NHL or relapsed/refractory MCL. The primary hypothesis is that MK-0683 will show efficacy in relapsed/refractory FL patients as measured by the Overall Response Rate.

The primary objective is to determine the maximum tolerated dose (MTD) of SAR3419 according to the dose limiting toxicities (DLTs) observed when administered as a single agent once weekly. Secondary objectives are: to characterize the global safety profile to evaluate the pharmacokinetic (PK) profile of SAR3419 in the proposed dosing schedule to assess preliminary evidence of anti-lymphoma activity.
