Filter by:This is a multicenter prospective single arm phase II study, and the purpose of this study is to evaluate the safety and efficacy of orelabrutinib combined with obinutuzumab and lenalidomide in untreated marginal zone lymphoma. The primary objective was the best complete response rate (CRR).
Describe the clinical features, diagnosis and treatment status, disease course and primary outcomes of different subtypes of marginal zone B-cell lymphoma (MZL), observe the therapeutic efficacy and safety of different treatment modalities.
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 is a non-randomized clinical trial to evaluate the safety and efficacy of CD22CART administered after lymphodepleting chemotherapy in adults with relapsed / refractory B Cell Lymphomas. All evaluable participants will be followed for overall survival (OS), progression free survival (PFS), and duration of response (DOR). An evaluable participant is one who completes leukapheresis, lymphodepleting chemotherapy and CART infusion.
CXCR4 is type of receptor that has been detected in more than twenty different subtypes of cancers. Most of these cancers are associated with negative symptoms that worsen over time resulting in great disability and poor function. There is a need for novel tracers to image CXCR4-expressing tumors for better detection, staging, and monitoring of aggressive cancers without the need for invasive biopsy procedures that may not always properly capture the extent of a patient's disease. This study looks to assess the safety and efficacy of a novel radiopharmaceutical known as 18F-BL40 through its use in a PET/CT scan. Participants will receive 2 PET/CT scans: 18F-BL40 and 18F-FDG as part of this study.
This study evaluates the incidence and management of new and worsening high blood pressure in patients with B-cell cancers on BTKi treatment.
