Filter by:The purpose of this study is to evaluate the safety, efficacy and blood kinetics of autologous T cells genetically modified to express CD19 Chimeric Antigen Receptor and PD-1 knockout engineered T cells in patients with relapsed or refractory B-Cell Non-Hodgkin Lymphoma and Leukaemia.
Acute leukaemias (AL) are the first cause of cancer in children, with a majority of B acute lymphoblastic leukemia (ALL). Some of the processes causing leukemogenesis are already identified and well characterized in some AL subtypes such as translocation t (12; 21) of good prognosis in ALL. However, translocations are not sufficient to explain all the different processes of leukemogenesis, and other processes such as genetic / epigenetic mutations leading to oncogene activation / inhibition of tumor suppressor genes are the object research. Among the latter, mutations in tumor suppressor genes such as DCC (Deleted in Colorectal Cancer) have recently been identified in solid cancers, such as in hemopathies. This gene was subsequently characterized as encoding a "dependence receptor" specifically binding to its Netrin-1 ligand. Dependence receptors (RDs) are transmembrane receptors that cause cell death in the absence of their ligand. RD decreases tumor progression and overexpression of their ligands is observed in many cancers, such as B lymphomatous hemopathies in adults. Inhibition of the RD-ligand interaction constitutes a new and original therapeutic target in oncology. The aim of this study is to investigate whether RDs, in particular DCC, are expressed in acute leukemia cells at the time of diagnosis or relapse in patients aged 1 to 18 years, and then in these patients at the time of the remission balance. This research will be both qualitative and quantitative.
Acute lymphoblastic leukemia , also known as acute lymphocytic leukemia, characterized by the overproduction and accumulation of cancerous, immature white blood cells, known as lymphoblasts, causing damage and death by inhibiting the production of normal cells (such as red and white blood cells and platelets) in the bone marrow and by spreading (infiltrating) to other organs. Acute lymphoblastic leukemia is most common in childhood, with a peak incidence at 2-5 years of age and another peak in old age.
Chronic lymphocytic leukemia is the most common type of chronic leukemia, accounting for approximately 40% of all leukemias and mainly affecting older individuals. As it has a highly variable clinical course, identification of molecular and biological prognostic markers has provided new insights into the risk stratification of patients with chronic lymphocytic leukemia.
This study involves adding the kinase inhibitor Ruxolitinib to Ibrutinib to treat Chronic Lymphocytic Leukemia (CLL).
Using phage libraries extensively pre-absorbed on a series of normal cell types, we will isolate phage specifically internalized by B-CLL cells from newly diagnosed and untreated CLL patients. Peptide sequences are then derived by Next Generation Sequencing (NGS). NGS-based studies are contributing to an improved understanding of cancer heterogeneity in order to tailor treatment to patients based on the individual makeup of their tumor. However the use of NGS to derive phage displayed peptide sequences is so far rare (22). Traditionally, after exposure to a target and recovery by elution, the phage clones are isolated by titration on bacterial lawns. It is technically demanding and labour intensive to select and analyze more than about 15 of the sometimes thousands clones recovered. Therefore information on other potentially important sequences is missed. NGS allows sequencing of the entire recovered phage pool and provides far more detailed bioinformatic analyses of peptide sequences or motifs. RNA from the CLL cells is used for RNA-seq expression sequencing. The wide application of NGS in combination with bioinformatics tools has begun to revolutionize cancer research, diagnosis and therapy. The peptide and RNA sequencing data will afford bioinformatic testing of correlations of exome expression and clinical parameters with the pattern of peptide sequences internalized by CLL cells of different patients. This information is crucial to answering questions 1, 2 and 3 discussed on page 1 above. The results of this analysis will probably not allow identification of specific receptors targeted by the peptides. The aim at this stage of the research is to identify candidate targeting peptides. Once identified, further research will be needed to identify the receptors to which they bind. Regarding question 4, there is currently very little published information on the therapeutic potential of PDCs in leukemia. Using two peptides we have isolated that target murine A20 leukemic cells, we will prepare multi-drug PDCs (using technology we have developed) and in an animal model, test their ability to enhance the survival and quality of life of CLL bearing animals.
CLL is a disease of the elderly, identifying effective therapies with better toxicity profiles is thus a high priority, and targeted therapies may allow attainment of this goal.
The purpose of this study is to determine whether the combination of As2O3 and ibrutinib is synergistic in chronic lymphocytic leukemia
The aim of our study is to improve the major molecular remission(MMR) rate and reduce the cost to treat ph(+) Acute Lymphoblastic Leukemia (ALL) by adjusting chemotherapy regimens and the dosage of Tyrosine Kinase Inhibitor (TKI). lower the classification of chemotherapy drugs, lower the side effect brought by which this would be a grateful news for the patients once this regimens gain a successful result, which is also the final aim of our efforts.
The purpose of this study is to determine whether deferasirox is effective in the treatment of acute lymphatic leukemia (ALL) and acute Myeloid leukemia (AML).
