Filter by: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.
The primary objective of this study is to determine the recommended phase 2 dose (RP2D) and characterize the safety profile of TG-1801. As per protocol v3.0, ublituximab will be discontinued.
This is a Phase 3 double-blind, placebo-controlled, randomized study designed to investigate whether tafasitamab and lenalidomide as an add-on to rituximab provides improved clinical benefit compared with lenalidomide as an add-on to rituximab in patients with R/R FL Grade 1 to 3a or R/R MZL.
This is a multicenter open label phase II trial in patients with previously treated Marginal Zone Lymphomas. The aim of the study is to evaluate the efficacy and the safety of tafasitamab in combination with acalabrutinib. Twenty-four patients are expected to be enrolled and treated every 28 days with acalabrutinib and tafasitamab for 24 cycles. The study consists of two parts, which are performed sequentially. The first part is a safety run-in to evaluate the safety data once 6 patients (representing the 25% of the total cohort) have completed the first cycle of treatment. An Independent Data Monitoring Committee (IDMC) will provide an independent assessment of this evaluation. The second part starts after the outcome of this evaluation and will include the remaining 18 patients. The 6 patients of the safety run-in phase will be considered for the final evaluation of the study. Between 11 - 13 weeks, patients showing partial or complete response (PR, CR) will continue treatment, while patients showing stable disease (SD) will discontinue it. However, patients in SD who benefit from therapy may continue to be treated, after agreement between the Investigator and the Sponsor. Patients who complete the 24 cycles of treatment will enter the follow-up phase up to 3 years from patient's last study treatment dose (about 5 years from treatment start). Patients who discontinue treatment before cycle 24 for any reason will be followed for up to 3 years (every 6 months for the first year and yearly for the second and third year) from the patient's last study treatment dose. .
Background: B-cell lymphoma is a cancer of certain white blood cells (called lymphocytes). These cells are found in lymph nodes. The cancer can cause enlargement of the lymph nodes leading to pain and discomfort. Swollen lymph nodes can also press on nearby organs such as liver and kidneys which can affect normal functioning of the organs. Researchers think that a new combination of drugs may be able to help. Objective: To find out if it is safe to give the combination of Magrolimab, Obinutuzumab and Venetoclax to people with B-cell lymphomas. Eligibility: Adults age 18 and older with an indolent B-cell lymphoma whose disease has returned or progressed after other treatment. Indolent B-cell lymphoma for this protocol is defined as having either follicular lymphoma, mantle cell lymphoma, chronic lymphocytic leukemia/small lymphocytic lymphoma or marginal zone lymphoma. Design: Participants will be screened under a separate protocol. Participants will have 28-day 'cycles' of treatment. They will take Venetoclax by mouth daily. They will get Obinutuzumab and Magrolimab by intravenous (IV) infusion. Treatment will last for about 8 months. They may be able to have more cycles of treatment if their cancer is responding well. Participants will have physical exams, medical histories, and medicine reviews. Data about how they function in their daily activities will be obtained. They will have blood and urine tests. They may have bone marrow tests. Participants will have imaging scans. These will include computed tomography (CT) and/or magnetic resonance imaging (MRI) scans and positron emission tomography (PET) scans. Participants may give a cheek swab or saliva sample. They may give tumor tissue and bone marrow samples. These samples may be used for gene testing. Participants will have a follow-up visit about 30 days after treatment ends. Then they will have visits every 3 months for the first 2 years, every 6 months for the next 3 years, and then yearly after that.
The trial is an open-label, multi-center safety and preliminary efficacy trial of epcoritamab (EPKINLY™) in Japanese patients with relapsed, progressive or refractory B-cell lymphomas and Japanese patients with B-cell lymphomas that have achieved partial response (PR) or complete response (CR) following prior SOC. The trial consists of two parts: Part 1, dose escalation (phase 1), and Part 2, expansion (phase 2). The purpose of the dose-escalation part of the trial is to determine the maximum tolerated dose (MTD) and the recommended Phase-2 dose (RP2D), as well as to establish the safety profile of epcoritamab in Japanese patients with relapsed, progressive or refractory B-cell lymphoma and Japanese patients with B-cell lymphomas that have achieved partial response (PR) or complete response (CR). In the expansion part, additional patients will be treated with epcoritamab, at the RP2D and the purpose is to further explore and determine the safety and efficacy of epcoritamab. Part 2 of the trial will be initiated once the RP2D has been determined in Part 1. In Part 2, epcoritamab is investigated as a monotherapy and in combination with other standard of care (SOC) agents.
The purpose of this study is to test the safety of 19(T2)28z1xx CAR T cells in people with relapsed/refractory B-cell cancers. The researchers will try to find the highest dose of 19(T2)28z1xx CAR T cells that causes few or mild side effects in participants. Once they find this dose, they can test it in future participants to see if it is effective in treating their relapsed/refractory B-cell cell cancers. This study will also look at whether 19(T2)28z1xx CAR T cells work against participants' cancer.
This study will help researchers understand how effective the combination of venetoclax and rituximab is in treating MZL in people who have not received a previous treatment for their cancer.
The purpose of this study is to see if the combination of rituximab and ibrutinib can help people with marginal zone lymphoma who have not received treatment in the past. The study will also compare the combination of rituximab and ibrutinib with the combination of rituximab and placebo to see which combination works better.
This is a Phase 1/2 study of imvotamab in adult subjects with relapsed or refractory B-cell Non-Hodgkin Lymphoma. This study will consist of a dose-escalation stage, a combination stage, and a randomized dose-expansion stage where subjects will be enrolled into indication-specific expansion cohorts. imvotamab will be administered intravenously (IV). Additional CD20-positive NHL histologies (e.g. MZL and MCL), may be allowed with Medical Monitor approval during the Dose-Escalation Phase of the study.
