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

Ofatumumab is a drug that works by attaching to the CD20 molecule found on the surface of cancerous B cells, and then triggering the death of those cells. It is approved by the FDA for treatment of another B-cell cancer, chronic lymphocytic leukemia, and also has evidence of success in people who's B-cell lymphomas have relapsed after initial treatments. In this research study we are looking to see if ofatumumab is effective and safe in treating previously untreated B-cell NHL.

RATIONALE: Vaccines, such as dendritic cell therapy (DC) made from a person's tumor cells and white blood cells may help the body build an effective immune response to kill tumor cells. Cryosurgery kills cancer cells by freezing them. Giving vaccine therapy together with cryosurgery may kill more tumor cells. PURPOSE: This clinical trial studies giving vaccine therapy together with or without cryosurgery in treating patients with B-cell Non-Hodgkin's lymphoma.

The clinical efficacy of rituximab, a chimeric monoclonal antibody targeted toward the B-cell specific antigen CD20, was initially demonstrated in cases of follicular lymphoma (FL), but the use of this antibody has been extended over the last few years to the majority of subtypes of B-cell CD20 positive non-Hodgkin's lymphomas, with promising results thus far. In MZL, small numbers of case reports have chronicled the use of rituximab as a single agent or phase II trial combination with chemotherapeutic regimens. The results of the rituximab maintenance phase III trial demonstrated that patients with FL who continued to take rituximab monotherapy as a maintenance therapy after responding to an initial course of chemotherapy combined with or without rituximab experienced longer progression-free survival durations than did those who received no rituximab maintenance therapy. The efficacy of maintenance treatment after first-line induction treatment with R-chemotherapy was addressed in the international PRIMA (Primary Rituximab and Maintenance) study, which has enrolled 1,217 patients. The first results are eagerly awaited. Although MZL has better prognosis in TTP and OS than FL, both of them are classified as the same category of indolent lymphoma -characterized by frequent relapse and prolonged survival. According to the results of our survey, advanced stage MZL tends to be an indolent disease - characterized by prolonged survival with frequent relapses. Rituximab appears to contribute to better responses, but not in TTP. Thus, we should consider maintenance treatments for MZL patients, to extend their response duration.

Phase 2, open-label, non-randomized, monotherapy study to evaluate the safety and efficacy of ibrutinib in subject with relapsed/refractory Marginal Zone Lymphoma (MZL).

This research study will evaluate the safety and efficacy of a study drug called Umbralisib (also known as TGR-1202) alone as a possible treatment for Waldenstrom's Macroglobulinemia that has come back or that has not responded to standard treatment.

This study is a multicenter phase II trial which primary objective is to assess the anti-lymphoma activity of atezolizumab associated with a BCL-2 inhibitor (GDC-199, venetoclax) and an anti-CD20 monoclonal antibody (obinutuzumab) in three separate cohorts: relapsed/refractory follicular lymphoma (FL) patients relapsed/refractory aggressive (DLBCL) lymphoma patients relapsed/refractory other indolent (iNHL) lymphoma patients (MZL and MALT)

This study will be conducted to evaluate the efficacy of Bendamustine Plus Rituximab (BR) in patients with relapsed or progressive Marginal Zone B-cell Lymphoma (MZBCL).

RATIONALE: AR-42 may stop the growth of cancer cells by blocking some of the enzymes needed for cell growth. PURPOSE: This phase I trial is studying the side effects and best dose of AR-42 in treating patients with advanced or relapsed multiple myeloma, chronic lymphocytic leukemia, or lymphoma.

RATIONALE: Biological therapies, such as fusion protein cytokine therapy, may stimulate the immune system in different ways and stop cancer cells from growing. 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 fusion protein cytokine therapy together with rituximab may kill more cancer cells. PURPOSE: This phase I trial is studying the side effects and best dose of fusion protein cytokine therapy when given after rituximab in treating patients with B-cell non-Hodgkin lymphoma.

This phase II trial studies giving rituximab before and after a donor peripheral blood stem cell transplant in patients with B-cell lymphoma that does not respond to treatment (refractory) or has come back after a period of improvement (relapsed). Monoclonal antibodies, such as rituximab, can interfere with the ability of cancer cells to grow and spread. Giving rituximab before and after a donor peripheral blood stem cell transplant may help stop cancer from coming back and may help keep the patient's immune system from rejecting the donor's stem cells.
