View clinical trials related to DLBCL.
Filter by:Multi-center retrospective analysis of patients with DLBCL aged ≥80 years old treated with R-CHOP-14 compared to other regimens. Patient data including baseline characteristics, histology, dose intensity and treatment outcomes will be extracted from hospital medical electronic records. Relative dose intensity (RDI) will be calculated as the percentage of the dose intensity achieved divided by the intended dose intensity. Primary endpoints are overall (OS), progression-free (PFS) and event-free survival (EFS), defined as time from diagnosis to death, death or progression/relapse, progression/relapse or treatment discontinuation.
Large-cell B-cell lymphoma (DLBCL) is the most common non-Hodgkin's lymphoma and accounts for about 40% of new cases. Although the DLBCL is a single entity in the WHO classification, several subgroups with different prognoses are recognized. These subgroups take into account the tumor localization (primitive cerebral lymphoma, serous lymphoma, intravascular or exclusive lymph node) or a particular molecular signature (GCB profile, germline center B cell or ABC, activated B cell). Despite the introduction of immunotherapy, treatment failures are common. Overall survival at 5 years is estimated to be between 26 and 73%. This highlights the important heterogeneity of this pathology and therefore the need for biomarkers prognosis. Recently, an increase in monocytes in the blood of DLBCL patients has been proposed as a prognostic factor for independent survival. This marker of poor prognosis is also found in many solid. Monocytes are effectors of the inflammatory response. They have different functional profiles depending on the level of expression of CD14 and CD16. Four subtypes of monocytes are distinguished: classical (CD14posCD16neg), intermediate (CD14posCD16pos) and non-classical (CD14lowCD16pos); the latter population is divided into two sub-groups depending on the expression of the SLAN protein. The different monocytic subpopulations have very diverse functions ranging from an immunosuppressive profile to an activation of the immune system. CD14posCD16neg monocytes are specialized in phagocytosis, production of oxygen derivatives (ROS) and pro-inflammatory cytokine secretion in response to microbial infection. CD14dimCD16pos monocytes are specialized in immune surveillance and produce proinflammatory cytokines such as TNFα and IL-1β in response to LPS stimulation.7 The Slanpos subpopulation produces IL-12 and thus has pro-inflammatory properties. Finally, CD14posCD16pos monocytes have controversial functions. For some authors, they produce the immunomodulatory cytokine IL-10, inhibit the proliferation of CD4 T lymphocytes and induce the recruitment of regulatory T lymphocytes, while for others they produce TNF-α, a pro- inflammatory.From a practical point of view CD14 and CD16 expression forms a continuum, which translates into complexity in the phenotypic definition of these cells and explains the contradictory data on their functionalities. Interestingly, in a laboratory work and in the course of publication, this fraction is increased in the blood of DLBCL patients compared to healthy donors (manuscript in preparation), on the contrary the monocytic fraction CD14dimCD16 pos is decreased in these patients. In the end, if the increase in monocytes is known to be poor prognosis in patients with DLBCL, the monocyte fraction involved and the monocytic functions involved in this phenomenon are not known. Since 2011, the Clinical and Biological Hematology Services have a database from a research protocol (BMS_LyTrans). This protocol includes patients with DLBCL as well as healthy patients, in order to allow the biological characterization of biomarkers in this pathology. Thus, we have blood samples and analysis of certain monocyte subtypes by flow cytometry at diagnosis, in more than 100 patients with DLBCL.
This is a Phase 1 platform protocol designed to evaluate various targeted agents for the treatment of relapsed/refractory aggressive Non-Hodgkin's Lymphoma (NHL).
The purpose of this study is to test the safety and efficacy of AUTO3, a CAR T cell treatment targeting CD19 and CD22 followed by limited duration of anti-PD1 antibody in patients with DLBCL
This is a Phase 1/2, open-label, dose-escalation, dose-expansion study for the treatment of patients with advanced cancers. Eligible patients with DLBCL or other advanced lymphomas will be enrolled into the dose-expansion cohort.
Diffuse Large B-cell Lymphoma (DLBCL) is the most frequent high grade lymphoma in adults. Although immunotherapy has improved its prognosis, DLBCL is a heterogeneous disease with patients exhibiting a wide range of outcomes with a 5-year overall survival ranging between 55 to 94% depending of the International Prognostic Index factor. Diagnostic and prognostic biomarkers are mandatory to optimize treatment. Transcriptomics has been used to detect such new biomarkers using microarrays analyses applied to RNA collected from total tumor tissues or cell extracts. Molecular prognostic factors have been thoroughly studied in DLBCL tumor tissues. However, it is a big challenge to obtain transcriptomic-qualified tumor samples in a multicentric and prospective clinical trial. Coordinating nvestigator hypothesized that blood may be a deep source of native and secreted analytes and therefore carries transcriptomic signatures related to DLBCL and its prognosis. This project is organized in the extension of the GOELAMS-075 clinical trial which concerns aggressive DLBCL.
In this study, the investigators purpose is to evaluate the adaptation of treatment with early response based on PET scan results after 2 cycles of chemotherapy, for patient aged from 18 to 80 years, with low IPI DLBCL. This is an open randomized study. The primary endpoint is to evaluate the 3 years PFS with the aim to demonstrate the non inferiority of the experimental arm in comparison to standard arm: In standard arm, the patients will receive 6 cycles of R-CHOP 21 without taking into account of PET scan results after 2 cycles. In experimental arm, early good responder patients (defined as having a negative PET scan after 2 cycles, confirmed after 4 cycles) will receive only 4 cycles of R-CHOP 21. In both arms, if the PET scan remains positive after 4 cycles of chemotherapy, a biopsy exam is needed to confirm the failure and an intensive chemotherapy is then recommended. All of the patients, in both arms, will have an early evaluation with PET scan. All PET scan will be reviewed by a group of expert according to Deauville criteria defined by Meignan et al to adapt the decision after the 2nd cycle in experimental arm and after the 4th cycle for all patients. The final evaluation of response will be made according to 2007 Cheson's criteria.
This is a prospective international, multi-center, randomized, double-blind controlled study designed to assess and compare the pharmacokinetics, pharmacodynamics and the safety of MabThera® and TL011, in combination with CHOP in previously untreated patients with diffuse large B cell lymphoma.
