Active clinical trials for "Lymphoma, B-Cell, Marginal Zone"

The primary objective of this study is to assess the antitumor activity (in terms of overall response rate - ORR - i.e. sum of complete and partial responses)of bortezomib in pretreated MALT lymphomas with one prior sistemic therapy regimen

Assess the therapeutic activity and safety of the combination of Chlorambucil and Rituximab in MALT lymphomas and determine whether the addition of Rituximab to Chlorambucil will improve the outcome of MALT lymphoma in comparison to treatment with Chlorambucil alone. In April 2006, a third arm of treatment was added to compare the antitumor activity and safety of rituximab alone vs chlorambucil alone

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

Evaluation of event free survival (EFS) of patients treated with the study chemotherapy induction program: R-CHOP compared to the standard R-CVP regimen and response rates, time to best response, PFS, OS, neutropenic fever rate, infection rate, change in Ig levels, change in lymphocyte subpopulations counts in previously untreated indolent lymphoma patients in need of systemic treatment.

Pre-clinical data and recently published clinical data suggest a synergistic effect between lenalidomide and dexamethasone. We hypothesize that a combination of lenalidomide-dexamethasone can overcome rituximab resistance. To determine the response rate to lenalidomide and dexamethasone plus rituximab therapy in subjects with recurrent small B-cell non-Hodgkin lymphoma who have had lymphoma progression within 6 months of being treated with rituximab alone or with a rituximab-containing regimen, we propose initial treatment with both drugs for two 28-day treatment cycles (Part I). After response assessment following two cycles of lenalidomide-dexamethasone, patients will enter Part II of the study. In Part II, patients will receive lenalidomide-dexamethasone and rituximab to evaluate the potential reversal of rituximab resistance as measured by response to rituximab and progression-free survival following rituximab.

Drugs used in chemotherapy, such as CCI-779, work in different ways to stop cancer cells from dividing so they stop growing or die. This phase II trial is studying how well CCI-779 works in treating patients with recurrent or refractory B-cell non-Hodgkin's lymphoma or chronic lymphocytic leukemia.

This phase I trial is studying the side effects and best dose of EMD 121974 in treating patients with solid tumors or lymphoma. Cilengitide (EMD 121974) may stop the growth of cancer cells by stopping blood flow to the cancer

Bortezomib may stop the growth of cancer cells by blocking the enzymes necessary for their growth. Drugs used in chemotherapy, such as flavopiridol, work in different ways to stop cancer cells from dividing so they stop growing or die. Bortezomib may increase the effectiveness of flavopiridol by making cancer cells more sensitive to the drug. Giving bortezomib together with flavopiridol may kill more cancer cells. This phase I trial is studying the side effects and best dose of bortezomib and flavopiridol in treating patients with recurrent or refractory indolent B-cell neoplasms.

This phase II trial studies the side effects and the best dose of alemtuzumab when given together with fludarabine phosphate and low-dose total body irradiation (TBI) and how well it works before donor stem cell transplant in treating patients with hematological malignancies. Giving chemotherapy and low-dose TBI before a donor peripheral blood stem cell transplant helps stop the growth of cancer cells. It may also 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 also make an immune response against the body's normal cells. Giving cyclosporine (CSP) and mycophenolate mofetil (MMF) after transplant may stop this from happening.

Phase II trial to study the effectiveness of combining bryostatin 1 with vincristine in treating patients who have progressive or relapsed non-Hodgkin's lymphoma after autologous bone marrow transplantation or autologous stem cell transplantation. Drugs used in chemotherapy such as vincristine use different ways to stop cancer cells from dividing so they stop growing or die. Bryostatin 1 may help vincristine kill more cancer cells by making the cells more sensitive to the drug
