Active clinical trials for "Lymphoma, B-Cell"

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.

The purpose of this research is to compare reactions and antibody responses following receipt of different doses of the experimental influenza vaccine or standard influenza vaccine.

The purpose of this study is to define the safety profile of rituximab given intrathecally in lymphomatous meningitis related to CD20+ non-Hodgkin's lymphomas.

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 purposed of this study is to determine whether an infusion with specialized 'modified T cells' (or CD19 chimeric antigen T cells, also called CD19 CAR T cells) that target the B cell marker will reduce the risk of relapse after transplant.

The goal of this observational study is to evaluate the anti-lymphoma activity of glofitamab, administered according to the Compassionate Use Program, in relapsed/refractory B-NHL patients. The main question it aims to answer is the rate of patients in complete response.

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.

This is an observational retrospective and prospective multicenter study aimed at describing the role of the COVID -19 prophylaxis with Tixagevimab and Cilgavimab in CLL or indolent B-NHL patients who received first COVID-19 prophylaxis dose between March 2022 and October 2022.
