Active clinical trials for "Lymphoma, B-Cell"

This multicenter, observational study will evaluate the correlation between clinical and biological factors and International Prognostic Index (IPI) as prognostic factors in patients with diffuse large B-cell lymphoma receiving first-line treatment with MabThera/Rituxan (rituximab) in combination with CHOP chemotherapy. Eligible patients receiving treatment according to standard of care and local guidelines will be followed for the duration of treatment (approximately 8 months) and during 1 year of follow-up.

Marginal zone B-cell lymphoma (MZL) is a lymphoma originated from B-cell in lymph node with variable differentiation status, which is distributed to a variety of organs. A high response rate and long term survival is possible through surgery or radiation therapy alone in the case of limited disease. However frequent relapse and progression is observed despite of long term survival. The treatment after relapse has not been established yet. So we investigate the efficacy of radioimmunotherapy using 131I-rituximab in refractory or relapsed patients with MZL.

The aim of this study is to optimize the number of cycles of R-CHOP in patients with diffuse large B-cell lymphoma based on the interim results of PET/CT.

Patients receive anti-CD19-CAR (coupled with CD137 and CD3 zeta signalling domains)vector-transduced autologous T cells over a period of 4 or 5 consecutive days in an escalating dose. After completion of study treatment, patients are followed intensively for 6 months, every 3 months for 2 years, and annually thereafter for 10 years.

This study aims to evaluate the safety, efficacy and duration of response of CD19 Chimeric Antigen Receptor (CAR) redirected allogeneic T-cells in patients with chemotherapy-resistant or refractory CD19+ B cell lymphoma.

This prospective trial will assess the activity and feasibility of a new high-dose methotrexate-based high-dose sequential chemotherapy combination in patients with B-cell lymphomas and CNS involvement at diagnosis or relapse. Selected drugs, with a well-documented anti-lymphoma activity, will be administered at high doses to increase blood-brain barrier penetration and CNS bioavailability as well as to reduce potential cross-resistance.

Poor prognosis dufuse large B-cell lymphoma (DLBCL) represents 50% of all DLBCL with overall cure rates ranging from 50-60% with modern dose-dense immunochemotherapy regimens such as R-CHOP14. Using an alternative strategy, as infusional and dose-adjusted R-EPOCH, the investigators have shown an 83% of complete responses (CR), with an estimated 5-year overall survival (OS) rate of 75% (García-Suárez et al. British Journal of Haematology 2007, 136:276). Despite this improvement in outcome, the search for new treatment strategies should continue. Therefore, compared with prior R-EPOCH the investigators decided to investigate whether the introduction of dexamethasone (40 mg IV on days 1-5) in place of prednisone (based upon data which demonstrated that the former was associated with enhanced Central Nervious System penetration) and the reduction of treatment intervals from 3 to 2 weeks would be feasible and might improve the outcome in this group of patients.

This is a two stage, Phase I/II clinical trial for patients with relapsed or refractory primary mediastinal large B-cell lymphoma (rrPMBCL). In the first stage, the participants will receive GVD (Gemcitabine, Vinorelbine and Doxorubicine) chemotherapy and PD-1 antibody (SHR-1210) treatment. The safety and efficacy of combined regimen will be evaluated. If deemed safe and efficacious, the investigators will proceed to the second stage of the study. In the second stage, the participants will receive GVD chemotherapy and SHR-1210 treatment with low-dose Decitabine priming. The safety and feasibility of combined regimens will be evaluated in phase I study. The feasibility will be accessed.
