Active clinical trials for "Lymphoma, Large B-Cell, Diffuse"

Primary Objective: Participants Achieving an Objective Response Rate (Cheson 2007) Secondary Objectives: Progression Free Survival Overall Survival Response Duration

Background: Mantle cell lymphoma (MCL) and diffuse large B-cell lymphoma (DLBCL) are aggressive subtypes of non-Hodgkin lymphoma. Flavopiridol is an investigational drug that works differently from standard chemotherapy and may target abnormalities in MCL and DLBCL cells, such as a protein excess that prevents tumor cells from dying. A challenge in developing flavopiridol for treatment has been determining its optimal dosing schedule. The schedule used for this study is effective in a type of leukemia called chronic lymphocytic leukemia (CLL) and may benefit patients with MCL and DLBCL also. Objectives: To determine the highest dose of flavopiridol that can be given safely to patients with relapsed MCL and DLBCL at the dosing schedule detailed below To assess the response of the tumor to flavopiridol given at the test dosing schedule Eligibility: Patients 18 years of age and older with relapsed MCL or DLBCL Design: Flavopiridol is given at four different dose levels, starting with the lowest dose for the first group of three to six patients and increasing with subsequent groups, depending on side effects at the preceding dose. The drug is given weekly for 4 weeks followed by a 2-week break (one cycle) for up to six cycles. It is given through a vein as a 30-minute infusion followed by a 4-hour infusion. Patients undergo the following procedures for research studies and to evaluate the effect of treatment on the tumor: Blood tests Lymph node, bone marrow and tumor biopsies Lymphapheresis to collect blood cells for research Disease staging with imaging studies (computed tomography (CT), positron emission tomography (PET) and/or magnetic resonance imaging (MRI) after every 2 cycles

This phase I trial is studying the side effects and best dose of vorinostat in treating patients with metastatic or unresectable solid tumors or lymphoma and liver dysfunction. (closed for accrual as of 04/05/2010) Vorinostat may stop the growth of cancer cells by blocking some of the enzymes needed for cell growth. Vorinostat may have different effects in patients who have changes in their liver function.

The purpose of this study is to compare the standard CHOP-R regimen of Cyclophosphamide, Doxorubicin, Vincristine, Prednisone, and Rituximab to CPOP-R (same regimen, but substituting Doxorubicin with Pixantrone). The objective is to show that CPOP-R is not inferior to CHOP-R.

This phase I trial is studying the side effects and best dose of vorinostat when given together with decitabine in treating patients with advanced solid tumors or relapsed or refractory non-Hodgkin's lymphoma, acute myeloid leukemia, acute lymphocytic leukemia, or chronic myelogenous leukemia. Vorinostat may stop the growth of cancer cells by blocking some of the enzymes needed for cell growth. Drugs used in chemotherapy, such as decitabine, 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 decitabine may kill more cancer cells.

This phase I trial is studying the best dose of 3-AP and the side effects of giving 3-AP together with gemcitabine in treating patients with advanced solid tumors or lymphoma. Drugs used in chemotherapy, such as 3-AP and gemcitabine (GEM), work in different ways to stop the growth of cancer cells, either by killing the cells or by stopping them from dividing. 3-AP may help gemcitabine kill more cancer cells by making the cells more sensitive to the drug. 3-AP may also stop the growth of tumor cells by blocking some of the enzymes needed for cell growth.

This phase I trial is studying the side effects and best dose of vorinostat when given together with isotretinoin in treating young patients with recurrent or refractory solid tumors, lymphoma, or leukemia. Drugs used in chemotherapy, such as vorinostat, work in different ways to stop the growth of cancer cells, either by killing the cells or by stopping them from dividing. Vorinostat may also stop the growth of cancer cells by blocking some of the enzymes needed for cell growth and by blocking blood flow to the cancer. Isotretinoin may cause cancer cells to look more like normal cells, and to grow and spread more slowly. Giving vorinostat together with isotretinoin may be an effective treatment for cancer.

Conventional therapy is effective for diffuse aggressive lymphomas and low grade lymphomas, but is limited by relapse occurs in 40 to 50% of subjects. This study assesses autologous stem cell transplant (ASCT) supplemented with high-dose therapy increases the event-free survival in diffuse aggressive lymphomas and low grade lymphomas, as an alternative to the limitations of conventional therapy. Preliminary studies with rituximab in low grade lymphomas indicate a response rate of about 50% with very little toxicity. Rituximab is hypothesized to be a candidate for post-transplant therapy because the majority of malignant lymphomas express the CD20 antigen; rituximab has impressive independent anti-tumor activity; and the antibody has little toxicity outside of the acute administration.

RATIONALE: Drugs used in chemotherapy work in different ways to stop tumor cells from dividing so they stop growing or die. Combining chemotherapy with stem cell transplantation may allow the doctor to give higher doses of chemotherapy drugs and kill more tumor cells. Monoclonal antibodies, such as rituximab, can locate tumor cells and either kill them or deliver tumor-killing substances to them without harming normal cells. It is not yet known whether stem cell transplantation is more effective with or without rituximab in treating relapsed or progressive B-cell diffuse large cell lymphoma. PURPOSE: Randomized phase III trial to compare the effectiveness of stem cell transplantation with or without rituximab in treating patients who have relapsed or progressive B-cell diffuse large cell lymphoma.

This study will measure the effectiveness and any side effects of LY317615 in participants with diffuse large B-cell lymphoma (DLBCL: a sub-type of Non-Hodgkins Lymphoma).
