Active clinical trials for "Lymphoma"

Treatments-related cardiotoxicity is a critical issue in long term lymphoma survivors, particularly at young age, and its early identification is important to prevent clinically relevant cardiac events. Complete echocardiographic assessment including 2-dimension global longitudinal strain (2D-GLS), seems to be an effective tools in detecting preclinical systolic changes to the cardiac function even when the ejection fraction is preserved. The aim of Cardiocare study is to investigate early detection of subclinical chemo and radiation-induced changes in left ventricular function using 2D-GLS.

The purpose of this study is to describe the effectiveness (overall response rate [ORR] and time to progression [TPP]) of Ibrutinib therapy in participants with chronic lymphocytic leukemia (CLL) and mantle cell lymphoma (MCL).

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.

Relapse after autologous hematopoietic stem cell transplantation (ASCT) is still challenging for high-risk aggressive lymphoma. This study was to investigate the efficacy and safety of maintenance therapy post-ASCT.

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 study aims to collect clinical data, mainly focused on safety, in the local target population as per the requirement of Korea Ministry of Food and Drug Safety for market authorization. The study population comprises patients with approved local indications chronic lymphocytic leukemia (CLL) and/or follicular lymphoma (FL) in routine clinical practice after launch.

A non-interventional, multicenter, multinational retrospective analysis using electronic case report forms completed by the investigators based on information from patient medical records

This is a prospective, multicenter, non-interventional study to test the safety and effectiveness of MabThera administered subcutaneously in participants with NHL or CLL. The length of study is expected to be 6 years.

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).

The purpose of this study is to evaluate whether a semi-quantitative interpretation using the liver SUVmax as reference can better interpret 18F- FDG PET/CT and predict disease progression during chemotherapy or survival in NK/T-cell lymphoma.
