Active clinical trials for "Lymphoma, B-Cell"

This will be a cohort study of all patients receiving Cluster of Differentiation 19 (CD19)-specific CAR T cell therapy for relapsed/refractory B cell haematological malignancies. Patients will receive cardiac assessment and have serum cardiac biomarkers, ECG, transthoracic echocardiogram and cardiac magnetic resonance imaging performed at baseline prior to CAR T cell therapy, 7 days post CAR T cell infusion, and 3 months post CAR T cell infusion. Abnormalities in these cardiac investigations will be used to demonstrate cardiac injury and identify which patients are most at risk of developing cardiac injury related to CAR T cell therapy.

This study enrolled patients with relapsed or refractory diffuse large B cell lymphoma treated with polatuzumab vedotin-based chemoimmunotherapies. Patients were allowed to use chemotherapy regimens other than Rituximab and Bendamustine and transplantation following polatuzumab vedotin was also allowed.

RATIONALE: Infection prophylaxis and management may help prevent cytomegalovirus (CMV) infection caused by a stem cell transplant. PURPOSE:This clinical trial studies infection prophylaxis and management in treating cytomegalovirus infection in patients with hematologic malignancies previously treated with donor stem cell transplant.

Evaluation of efficacy, safety profile and tolerability of rituximab (MabThera) in combination with chemotherapy in the treatment of Diffuse Large B-Cell Lymphoma (DLBCL). Participants, who were not treated previously for DLBCL, will receive MabThera in combination with Cyclophosphamide, Hydroxydaunorubicin, Oncovin, Prednisone (CHOP) or CHOP-like chemotherapy according to registered indication. Patients will be followed up for safety and efficacy evaluation in accordance with routine practice. The study will be non-interventional and by its design purely observational. All treatments prescribed during the observation period will be at the treating physician's discretion and will be prescribed according to package labeling, within approved indication and local approval status of respective drugs.

Central nervous system lymphoma (CNSL) is a rare brain tumor constituting 3% of all newly diagnosed brain tumors, and 2% to 3% of all cases of non-Hodgkin lymphoma. There are two subtypes of CNSL. Owing to its low incidence, there is limited prospective and/or randomized data to guide the therapy of CNSL. Current knowledge about optimal diagnostic, prognostic and therapeutic strategies of CNSL is urged. The immune system plays a fundamental role in controlling and eradicating cancer but is held in check by inhibitory receptors and ligands. These immune checkpoint pathways, which normally maintain self-tolerance and limit collateral tissue damage during anti-microbial immune responses, can be co-opted by cancer to evade immune destruction. A plethora of regulatory molecules have been identified. Among them, three have been studied most intensively: cytotoxic T lymphocyte antigen 4 (CTLA4) binding to CD80 or CD86, programmed cell death protein 1 (PD-1) binding to PD-1 ligand 1 (PD-L1) or PD-L2, and SIRPαbinding to CD47. Agents inhibiting CTLA-4, PD1, PD-L1 and CD47 are showing compelling antitumor activity in several solid and hematological cancers. Exploring the role of immune checkpoint pathways in CNSL may help us to establish the rational targeted therapies. In this study, the investigators will investigate the protein expression of several specific molecules in immune checkpoint pathways such as PD-L1, PD-L2 and CD47 in the large neurological resection specimens by immunohistochemical staining of patients with CNSL. Besides, the concentrations of above molecules and other prognostic relevant factors such as chemokine CXCL13, Interleukin-10 and soluble CD19 in the cerebrospinal fluid (CSF) at initial diagnosis and after treatment will be evaluated using enzyme-linked immunosorbent assays. About 100 patients with CNSL will be recruited. The protein expression of the above molecules will be correlated with the clinical outcome of patients with CNSL. The feasibility of adopting these CSF molecules as useful diagnostic or prognostic biomarkers in CNSL will also be investigated.

This is a non-interventional, retrospective cohort study using the Flatiron Health Research Database (FHRD) and data from the single-arm phase II JULIET clinical trial (NCT02445248).

This observational study aims to assess the therapeutic responsiveness of MabThera SC in patients with malignant lymphomas under everyday clinical practice conditions. Patients with previously untreated CD-20 positive follicular non-Hodgkin's lymphoma (NHL) or previously untreated CD-20 positive diffuse large B-cell lymphoma (DLBCL) who are planned for therapy with MabThera SC according to the assessment of the physician will be prospectively enrolled for observation. No study specific measures are required; treatment and documentation will be performed according to usual clinical practice.

This observational study will evaluate the safety and efficacy of MabThera/Rituxan (rituximab) plus chemotherapy as first-line treatment in patients with diffuse large B-cell lymphoma (DLBCL) or follicular lymphoma (FL). Data will be collected from each patient during the 6 months of induction treatment and for up to 3 years of follow-up.

Molecular imaging can be used for the noninvasive assessment of biodistribution of monoclonal antibodies. Atezolizumab has previously successfully been labeled with the radionucleotide Zirconium-89 (89Zr) and studied in solid malignancies (NCT02453984). The results of atezolizumab biodistribution can help to get a better understanding of the response mechanisms, the relation with minimal residual disease, the relation with the status of the T-cell and natural killer (NK)-cell repertoire and toxicity of programmed death ligand 1 (PDL1) checkpoint inhibition. Possibly in the future this will facilitate optimal patient selection. Sequential 89Zr-atezolizumab positron emission tomography (PET) scans can provide information on the dynamics of atezolizumab biodistribution over time. In combination with repeated characterization of tumor tissue and blood samples, these results can give inside in primary and acquired resistance. In this parallel study of the HOVON 151 trial, 89Zr-atezolizumab-PET-scans will be used to evaluate 20 high risk DLBCL patients before and after induction (R-CHOP) therapy, and at suspected relapse during or after atezolizumab consolidation (HOVON 151).

This research study is designed to test whether the results of a diffusion MRI scan performed after one cycle of chemotherapy for lymphoma can accurately predict the outcome of treatment for individual patients.
