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

Acute Graft-versus-Host-Disease (GVHD) is an important cause of morbidity and mortality after allogeneic hematopoietic stem cell transplantation (HSCT). This study aims to determine if any of three new GVHD prophylaxis approaches improves the rate of GVHD and relapse free survival at one year after transplant compared to the current standard prophylaxis regimen.

This phase II trial studies how well brentuximab vedotin, bendamustine, and rituximab work in treating patients with B-cell non-Hodgkin lymphoma that has returned after a period of improvement or has not responded to previous treatment. Monoclonal antibody-drug conjugates, such as brentuximab vedotin, use antibody to target chemotherapy in cancer cells. Drugs used in chemotherapy, such as bendamustine, work in different ways to kill cancer cells. Monoclonal antibodies, such as rituximab, kill the cancer cells directly, but also harness the immune system to kill the cancer cells. Adding brentuximab to rituximab may improve response rates in CD30 positive, CD20 positive Relapsed Refactory NHL.

The application of positron emission tomography with lymphoproliferative diseases today provides diagnostic and therapeutic information of major importance , especially in terms of speed and quality of response to treatment. The radiopharmaceutical used in clinical practice for this exam is fluorodeoxyglucose 18F-2-fluoro-2-deoxy-D-glucose fluorodeoxyglucose ([18F]-FDG) . However , the uptake of this tracer is not elective in lymphoid tissues , with a lack of specificity. In addition , the avidity of this tracer is unequal according to the histological subtype (lack of sensitivity). To try to improve the results of this clinical exploration of lymphoid malignancies, the investigators developed a new radiopharmaceutical ( [18F] - fludarabine ). The idea of transforming the fludarabine radiopharmaceutical is based on the existence of a fluorine atom in the molecule and the pharmacokinetic characteristics of this drug. The [18F]-Fludarabine is a new radiopharmaceutical reproducing the same dosage formulation of fludarabine , a drug used for the treatment of certain types of lymphoproliferative diseases, especially those where the tumor cells have a low proliferation kinetics . This drug is used in therapy in particular pharmacokinetic effect for a high affinity for the lymphoid tissue . Preclinical results on normal and lymphoma xenograft -bearing mice showed a specificity restricted to lymphoid tissue fixation with [18F]-Fludarabine compared with [18F]-FDG . Based on these encouraging results , the investigators propose in this work to explore the Dosimetry and Biodistribution of [18F] - Fludarabine in human lymphoproliferative diseases : 1)A first group of patients with non-Hodgkin's large cell lymphomas in which it already has a wealth of experience in exploration [18F]-FDG, and 2) a second group of patients with chronic lymphocytic leukemia, where the results of the exploration [18F]-FDG are considered disappointing and did not, for this reason, experienced clinical development.

This phase II trial studies how well giving rituximab together with combination chemotherapy works in treating patients with previously untreated high- or high-intermediate-risk diffuse large B-cell lymphoma (DLBCL). Monoclonal antibodies, such as rituximab, can block cancer growth in different ways. Some block the ability of cancer 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, doxorubicin hydrochloride, vincristine sulfate, and prednisone (CHOP), work in different ways to stop the growth of cancer cells, either by killing the cells or by stopping them from dividing. Giving more than one drug, combination chemotherapy, may kill more cancer cells. Giving rituximab together with combination chemotherapy together may be an effective treatment for DLBCL

This is a retrospective observational study of the therapeutic mechanism and resistance mechanism of the treatment of Selinexor combined with lenalidomide and rituximab in diffuse large B-cell lymphoma patients. By detecting the immune cells in peripheral blood and tumor tissues of patients before and after treatment, the key immune cell subsets and immune molecules linked to the action and resistance of the treatment of Selinexor combined with lenalidomide and rituximab, so as to provide the basis for the optimization of the treatment or the combination of other immunotherapies.

To estimate the I-year progression-free survival probability in patients up to 70 years of age with previously untreated diffuse large B-celllymphoma (DLBCL), or with intermediate (Burkitt-like) lymphoma, whose tumor cells show MYC rearrangement, and who are treated with alternating cycles of Rituximab-HCV AD and Rituximab-Methotrexate-Cytarabine, in concert with optimal supportive treatment including Pegfilgrastim, prophylactic antimicrobials, and close clinical follow-up.

The goal of this study is to identify biomarkers that will predict outcome to standard and targeted therapies in patients with relapsed/refractory diffuse large B-cell lymphoma (DLBCL). The specific aims of the present project are: To explore associations between expression of target antigens on surface of neoplastic cells of DLBCL patients and response to target therapies To identify specific miRNA signatures as predictors of response to upfront and salvage immune-chemotherapies in DLBCL patients. To refine the diagnosis and molecular profiling of DLBCL, and to provide biological information of prognostic relevance in the setting of innovative treatments of patients with DLBCL.

The purpose of the project is to set up a national, prospective, longitudinal, multicenter registry platform to document uniform data on characteristics, molecular diagnostics, treatment and course of disease, to collect patient-reported outcomes and to establish a decentralized biobank for patients with hematological malignancies in Germany.

Digital case management systems have the potential to increase compliance with protocol-driven treatment, reduce treatment abandonment and ultimately help to close the discrepancy in pediatric cancer outcomes between Low and Middle Income Countries (LMICs) and high-income countries (HICs). The investigators aim to adapt an open-source digital case management platform to incorporate standardized pediatric oncology protocols. Effectiveness will be evaluated by provider protocol compliance (primary outcome) and patient treatment abandonment rates using the digital case management system as compared to historic controls. The study population will include patients diagnosed with Burkitt lymphoma, Diffuse large B-cell lymphoma (DLBCL) or retinoblastoma at Bugando Medical Centre in Tanzania.

RATIONALE: Lithium carbonate may be an effective treatment for intestinal graft-versus-host disease caused by a donor stem cell transplant. PURPOSE: This clinical trial is studying lithium carbonate in treating patients with acute intestinal graft-versus-host-disease after donor stem cell transplant.
