A Phase 2 study to evaluate the efficacy of nanatinostat in combination with valganciclovir in patients with relapsed/refractory EBV-positive lymphomas
Hematological malignancies gather several various pathologies included myeloproliferative disorders (as acute myeloid leukemia (AML) or chronic myeloid leukemia (CML)) and lymphoproliferative disorders (as chronic lymphoid leukemia (CLL), non-Hodgkin lymphoma (NHL) and multiple myeloma (MM)) . Over the last decade, the treatments have evolved significantly but the overall survival remains limited, especially for the AML and MM patients. There's an ongoing imperative to continue in-vitro and in-vivo studies to better evaluate the anti-cancer drugs sensitivity and therefore improving the response to treatments and open new fields of application. The healthy control group will be contributing to produce some pertinent and significant data for the results of the index cases group. The investigators aim to analyze 10 differents drugs, common use in chemotherapy or immunotherapy and evaluate by 2 ways the sensitivity: first, Flow cytometry (cells apoptosis by Annexine V and propidium iodide) on fresh samples and in a second time, monitoring of the blasts in the mouse's blood after injection.
Epstein Barr virus infects over 90% of human population and persists during lifetime. After infecting B lymphocytes, EBV remains latent in memory B cells. In immunocompromised patients, primary infection could lead to an uncontrolled EBV infected B cells proliferation because of impaired T cell specific cytotoxicity. The latent EBV infection is characterized by expression of restricted latent gene products, which drive cell proliferation and progression to PTLD. As a consequence, EBV seronegativity and EBV mismatch are major risk factors for developing PTLD. The investigators reported in a previous work from the French Registry that the incidence of PTLD was multiplied by ten in adult EBV negative kidney transplant recipients. Moreover, even if the event is relatively rare after transplantation, the prognosis is severe with high morbidity and an overall mortality rate around 50%. Nowadays, few and inconsistent data exist regarding beneficial preventing strategies like antiviral therapy, reduction of immunosuppression or immunoglobulin infusion in this high-risk population of EBV negative recipients. Therefore, an efficient and safe preventive treatment is still lacking to decrease PTLD incidence. Rituximab, has been already proposed in stem cell transplant recipients as a preemptive therapy in patients with a persistent EBV viremia independently of their EBV status. A pilot study was performed in EBV negative kidney transplant recipients but in a very small population. Schachtner60 reported the cases of 5 EBV negative recipients receiving kidney from EBV positive donors after a treatment with Rituximab. Only 2 patients showed a seroconversion and no patients developed neither a viremia nor a PTLD after 49 months of follow-up. The main objective of the investigators study is to evaluate the efficacy of early infusion of Rituximab in the prevention of EBV primary infection and post-transplant lymphoproliferative disorder (PTLD) occurrence in adult EBV negative kidney transplant recipients transplanted with an EBV positive donor.
This phase II trial studies the effect of acalabrutinib and obinutuzumab in treating patients with follicular lymphoma or other indolent non-Hodgkin lymphoma for which the patient has not received treatment in the past (previously untreated). Acalabrutinib may stop the growth of cancer cells by blocking some of the enzymes needed for cell growth. Immunotherapy with obinutuzumab may induce changes in body's immune system and may interfere with the ability of cancer cells to grow and spread. Giving acalabrutinib and obinutuzumab may kill more cancer cells.
The main purpose of this study is to determine the effectiveness of the study drug pacritinib in people with relapsed or refractory lymphoproliferative disorders.
1. To study the expression pattern of CD19(cluster of differentiation antigen19) complex in lymphoproliferative disorders and its diagnostic value. 2. To investigate the biological significance of CD19 complex expression in lymphoproliferative disorders. 3. To explore the possibility of ectopic expression of CD19 complex in non B-lineage lymphoproliferative disorders.
This study is for patients that have a type of lymph gland disease called Hodgkin or non-Hodgkin Lymphoma or T/NK-lymphoproliferative disease which has come back or has not gone away after treatment, including the best treatment the investigators know for these diseases. Some patients with Lymphoma or T/NK-lymphoproliferative disease show signs of virus that is sometimes called Epstein Barr virus (EBV) that causes mononucleosis or glandular fever ("mono") before or at the time of their diagnosis. EBV is found in the cancer cells of up to half the patients with Hodgkin's and non-Hodgkin Lymphoma, suggesting that plays a role in causing Lymphoma. The cancer cells (in lymphoma) and some immune system cells infected by EBV are able to hide from the body's immune system and escape destruction. T cells, also called T lymphocytes, are special infection-fighting blood cells that can kill other cells, including cells infected with viruses and tumor cells. T cells have been used to treat patients with cancers. T cells, that have been trained to kill EBV infected cells can survive in the blood and affect the tumor. The investigators have treated over 80 people on studies using T cells to target these diseases. About half of those patients who had disease at the time they got the cells had responses including some patients with complete responses. The investigators think that if T cells are able to last longer in the body, they may have a better chance of killing EBV and EBV infected tumor cells. Therefore, in this study the investigators will add a new gene to the EBV T cells that can cause the cells to live longer called C7R. The investigators know that T cells need substances called cytokines to survive and the cells may not get enough cytokines after infusion into the body. The investigators have added the gene C7R that gives the cells a constant supply of cytokine and helps them to survive for a longer period of time. The purpose of this study is to find the largest safe dose of C7R-EBV T cells, and additionally to evaluate how long they can be detected in the blood and what affect they have on cancer.
This study is a Phase 2 trial designed to evaluate the clinical efficacy, safety, and tolerability of MAS825 in patients with NLRC4-GOF, XIAP deficiency, or CDC42 mutations.
The purpose of this study is to assess the efficacy and safety of tabelecleucel in participants with Epstein-Barr virus (EBV) associated diseases.
