Filter by:This phase II trial tests the safety, side effects and effectiveness of mosunetuzumab in treating patients with slow growing (indolent) B-cell lymphoma. Mosunetuzumab is a monoclonal antibody that may interfere with the ability of tumor cells to grow and spread.
Non-Hodgkin lymphomas (NHLs) constitute a heterogeneous group of malignant neoplasms, with diverse clinical behaviors and distinct pathologic and molecular characteristics. Among these lymphomas, follicular lymphomas (FLs), marginal zone lymphomas (MZLs) and diffuse large B-cell lymphomas (DLBCLs) emerge as the most prevalent entities. While FL and MZL are representative of indolent B-cell lymphomas, characterized by a slow progression of the disease and favorable clinical outcomes, DLBCL stands out as an aggressive lymphoma, often occuring from the transformation of a pre-existing indolent lymphoma. Chromosome translocations are a hallmark of some NHL subtypes, offering insights into their molecular pathogenesis. For instance, the conventional FL is genetically characterized by the t(14;18) chromosomal translocation, found in 85-90% of cases, resulting in sustained elevation of the antiapoptotic protein B-cell lymphoma 2 (BCL2). However, certain FL cases lack BCL2 translocations and exhibit distinct clinical, morphological and phenotypical features with genetic heterogeneity. A subset of BCL2-negative FLs displays rearrangements within chromosomal region 3q27, inducing abnormal modulation of B-cell lymphoma 6 (BCL6) expression. The BCL6 gene plays a critical role in germinal center development and B-cell differentiation. Previous investigations indicate that BCL6 rearrangements (BCL6-R) manifest distinct pathological and genetic features, diverging from classical FL presentations. FLs carrying BCL6-R commonly share a specific CD10- Bcl-2- Bcl-6+ phenotype, often accompanied by a monocytoid component and increased frequency of diffuse architectural patterns. Patients with BCL6-R tend to exhibit advanced clinical stages and complex genetic profiles. MZLs present differential diagnostic challenges due to shared monocytoid components, phenotypes traits, and common genetic features. The similarities observed between BCL6-R FL and MZL suggest a convergence in both morphological and genetic aspects, leading to intricate differentiation. Traditionally, these indolent NHLs with BCL6-R were categorized as FL and incorporated into the FL category in the WHO classification. However, few studies highlight the occurrence of BCL6-R in MZLs. This observation gives rise to the hypothesis that indolent NHLs exhibiting BCL6-R might correspond to a continuum comprising both FL and MZL. Additionally, BCL6-R has been frequently documented in DLBCL cases with residual MZL component. These DLBCL cases might display a mutational profile reminiscent of MZL. This suggests a plausible origin of BCL6-R DLBCL from indolent BCL6-R MZLs or BCL6-R FLs cases.
This phase II trial tests how well pirtobrutinib in combination with rituximab works in treating patients with marginal zone lymphoma (MZL). Pirtobrutinib is a BTK inhibitor. It works by blocking the action of the protein that signals tumor cells to multiply. Rituximab is a monoclonal antibody. It binds to a protein called CD20, which is found on B cells (a type of white blood cell) and some types of cancer cells. This may help the immune system kill cancer cells. Giving pirtobrutinib in combination with rituximab may be an effective treatment for MZL.
The purpose of the study is to establish the safety and efficacy of zanubrutinib in combination with rituximab for people with untreated B-cell lymphomas (marginal zone lymphoma and follicular lymphomas).
This phase II trial tests how well pemigatinib works in treating patients with mantle cell lymphoma (MCL) or marginal zone lymphoma (MZL) that has come back after a period of improvement (relapsed) or that does not respond to treatment (refractory). Pemigatinib may stop the growth of cancer cells by blocking some of the enzymes needed for cell growth.
Describe the efficacy and safety of Orelabrutinib in the treatment of HP-positive gastric MALT lymphoma
This phase I trial tests safety, side effects and best dose of B-cell activating factor receptor (BAFFR)-based chimeric antigen receptor T-cells, with fludarabine and cyclophosphamide lymphodepletion, for the treatment of patients with B-cell hematologic malignancies that has come back after a period of improvement (relapsed) or that does not respond to treatment (refractory). BAFFR-based chimeric antigen receptor T-cells is a type of treatment in which a patient's T cells (a type of immune system cell) are changed in the laboratory so they will attack cancer cells. T cells are taken from a patient's blood. Then the gene for a special receptor that binds to a certain protein on the patient's cancer cells is added to the T cells in the laboratory. The special receptor is called a chimeric antigen receptor (CAR). Large numbers of the CAR T cells are grown in the laboratory and given to the patient by infusion for treatment of certain cancers. Giving chemotherapy, such as fludarabine and cyclophosphamide, helps ill cancer cells in the body and helps prepare the body to receive the BAFFR based chimeric antigen receptor T-cells. Giving BAFFR based chimeric antigen receptor T-cells with fludarabine and cyclophosphamide for lymphodepletion may work better for the treatment of patients with relapsed or refractory B-cell hematologic malignancies.
This project proposes to establish a prospective, multicenter, randomized, controlled clinical study to compare the safety and efficacy of Intralesional Rituximab Injection versus Involved Site Radiation Therapy for the treatment of primary ocular adnexal MALT lymphoma. The aim is to provide high-level clinical evidence for the treatment of ocular adnexal MALT lymphoma and to offer patients treatment options that have fewer complications and comparable therapeutic effects.
This study is researching an experimental drug called odronextamab, referred to as study drug. The study is focused on patients who have one of two types of cancer: follicular lymphoma (FL) or marginal zone lymphoma (MZL) that has come back after treatment (called "relapsed"), or did not respond to treatment (called "refractory"). FL and MZL are subtypes of Non-Hodgkin 's lymphoma (NHL). This study will be made up of two parts (Part 1 not randomized, Part 2 randomized - controlled). The aim of Part 1 of the study is to see how safe and tolerable the study drug is when used in combination with lenalidomide, in participants with FL or MZL, and to determine the dose of the study drug to be used in Part 2 of this study. This combination is considered "first-in-human" as it has not been tested as a combination treatment in humans before. The aim of Part 2, of the study is to assess how the combination of odronextamab and lenalidomide works compared to the combination of rituximab and lenalidomide, (the current standard-of-care treatment for FL and/or MZL). Standard-of-care means the usual medication expected and used when receiving treatment for a condition. The study is looking at several other research questions, including: - What side effects may happen from taking the study drug in combination with lenalidomide - How much study drug is in your blood at different times - Whether the body makes antibodies against the study drug (which could make the study drug less effective or could lead to side effects) - The impact from the study drug on your quality-of-life and ability to complete routine daily activities
The goal of this clinical trial is to test the overall response rate of obrutinib combined with rituximab (OR regimen) for second-line treatment of refractory marginal zone lymphoma.
