Active clinical trials for "Lymphoma, Large B-Cell, Diffuse"

The purpose of this study is to collect long-term safety and efficacy data for participants treated with ibrutinib and to provide ongoing access to ibrutinib for participants who are currently enrolled in ibrutinib studies that have been completed according to the parent protocol, are actively receiving treatment with ibrutinib, and who continue to benefit from ibrutinib treatment.

Apoptosis is a specific form of cell death that leads to clearance of dead cells without causing inflammation or injury to normal adjacent tissues. Targeted cancer therapeutics that target this pathway for tumor cell death induction are in development, but few specific biomarkers of apoptosis are available to assess treatment response. Apoptosis also occurs in response to standard anthracycline or combination therapies such as rituximab, cyclophosphamide, doxorubicin, vincristine, and prednisolone (R-CHOP), rituximab, etoposide, phosphate, prednisone, vincristine sulfacte, cyclophosphamide, and doxorubicin hydrocholoride (R-EPOCH) used to treat many different histopathological types of lymphoma including Hodgkin and non- Hodgkin lymphoma such as diffuse large B-cell lymphoma (DLBCL), Burkitts lymphoma, primary mediastinal B-cell lymphoma and double hit DLBCL. Caspase-3 activation occurs as a result of apoptosis and may be a specific marker of apoptosis. Therefore, this study will assess whether 18F-FluorApoTrace (18F-FAT), a caspase-3 targeted tracer, has a reasonable dosimetry profile and can be used to detect apoptosis in patients with lymphoma being treated with standard therapy.

The purpose of this study is to determine the recommended phase 2 dose of the drug Vorinostat in children, adolescents and young adults following allogeneic blood or marrow transplant (BMT) and determine whether the addition of Vorinostat to the standard graft versus host disease (GVHD) prophylaxis will reduce the incidence of GVHD.

Diffuse large B-cell lymphoma (DLBCL) is the most common non-Hodgkin's lymphoma, accounting for 35% of lymphoma. Chimeric antigen receptor T cell (CAR-T) therapy is a new method to treat DLBCL. KTE-C19, published in the New England Medical Journal in December 2017, was used to treat relapsed and refractory B-cell lymphoma. One year of treatment for 111 patients, the total response rate was 82%, and the complete remission rate was 54%. However, a large number of clinical studies have shown that about 20% of patients with B-ALL and 50% of patients with B-NHL cannot achieve complete remission (CR) after CD19-CAR-T treatment. Targeting tumor microenvironment is an important new method to overcome the drug resistance of CAR-T cells. In this study, IL-7 and CCL19 were connected on the basis of traditional second generation CD19 CAR-T cells to construct novel fourth generation CAR-T cells, which can promote the infiltration, accumulation and survival of CAR-T cells in lymphoma tissue, and further enhance the anti-tumor effect of traditional CAR-T cells. At the same time, combined with four generations of CAR-T cells and PD1 monoclonal antibody, PD1 / PDL1 signal pathway was blocked, anti-tumor effect of CAR-T was improved, and immune response and long-term remission rate of DLBCL were improved.

This study is designed as a long-term follow-up study of participants who have receive genetically modified autologous CLBR001 CAR-T cells

Phase 2 Study of Abbreviated 3 Cycles of Rituximab plus CHOP (Cyclophosphamide, Adriamycin, Vincristine, and Prednisolone) Immunochemotherapy in Patients with Completely Excised Localized Gastrointestinal CD20 (+) Diffuse Large B-cell Lymphoma(SATURDAY STUDY)

A phase II trial of ifosfamide, etoposide, cytarabine, and methotrexate (IVAM) chemotherapy for refractory or relapsed diffuse large B cell lymphoma

Purinostat mesylate for injection (PM) was the novel and highly potent Class I a and IIb HDAC-selective inhibitors. The results of regular blood sampling analysis of the mouse B-cell lymphoma model induced by ighmyc transgenic mice showed that the treatment of PM in each group reduced the proportion of peripheral blood tumor cells in mice. Therefore, PM has the potential to treat diffuse large B cell lymphoma. The results of in vitro enzymatic activity screening showed that PM has high inhibitory activity on HDAC tumors (including HDAC1, 2, 3, 8 subtypes) and type II HDACs (including HDAC6, 10 isoforms), which are closely related to tumors in the HDAC family. Therefore, the results of in vitro enzyme activity screening showed that the IC50 values of PM for inhibiting HDAC1, HDAC2, HDAC3, HDAC8, HDAC6, and HDAC10 subtypes of HDAC class I and HDAC class IIb were 0.81, 1.4, 1.7, 3.8, 11.5, and 11 nM, respectively. However, the inhibitory activity of HDAC IIa and HDAC IV enzymes was low, and its IC50 values for HDAC4, HDAC5, HDAC7, HDAC9, and HDAC11 subtypes of HDAC IIa and HDAC IV were 1072, 426, 590, 622, and 3349 nM, respectively. These data means PM exist high selectivity for tumor-associated HDAC class I and HDAC IIb. Compared with the blank control group, the body weight of the tumor-bearing animals in each dose of PM group did not decrease seriously during the treatment process, and the animals were in good condition during the whole experiment, indicating that the PM is efficacy and safe. Main purpose: To further explore the safe and effective dose of priinostat mesylate for injection in the treatment of relapsed or refractory diffuse large B-cell lymphoma. To evaluate the objective response rate (ORR) of priinostat mesylate for injection in the treatment of relapsed or refractory diffuse large B-cell lymphoma. Secondary purpose: To explore the biomarkers related to the efficacy of priinostat mesylate for injection. To evaluate the time to tumor response (TTR), duration of response (DOR), disease control rate (DCR), and progression-free survival (PFS) in the treatment of relapsed or refractory diffuse large B-cell lymphoma with prilinostat mesylate for injection ), overall survival (OS). Assessing the safety and tolerability of priinostat mesylate for injection in the treatment of relapsed or refractory diffuse large B-cell lymphoma.

This trial is a translational, prospective, open-label, monocentric research. The study will be conducted in a population of 60 patients with diffuse large B-cell lymphoma (DLBCL) for whom first-line treatment with R-CHOP is planned as part of their standard of care. SIMILY program aims at identifying biomarkers and/or molecular signatures related to immuno-phenotypic and -genotypic characteristics of the tumor and immune microenvironment, at the time of diagnosis, during R-CHOP, and at 24 months or time of progression. Each patient will be followed during 2 years.

We hope to demonstrate that YESCARTA can be safely administered in the outpatient setting if we closely monitor subjects with physical exams, wearable devices, and telemedicine visits and only admit those who meet specified criteria
