Active clinical trials for "Leukemia"

This is a non-interventional, Phase 4 study designed to improve understanding of current clinical practice in the treatment of CLL/SLL and to describe treatment pattern and evaluate outcomes of ibrutinib-treated CLL patients in China. This study will include both retrospective and prospective data collection.

Acute myeloid leukemia (AML) is a heterogeneous disorder characterized by clonal expansion of myeloid progenitors (blasts) in the bone marrow and peripheral blood.Several studies have reported correlations of aberrantly expressed markers by flowcytometry with clinical outcome in AML. X-inactive specific transcript RNA was one of the first long noncoding RNAs (lncRNAs) to be discovered in the early 1990s. Xist RNA is the master regulator of XCI, the epigenetic process that equalizes the dosage of X-linked genes between female (XX) and male (XY) mammals. Yildirim et al., (2013) deleted Xist in the blood compartment of mice and demonstrated that mutant females developed a highly aggressive myeloproliferative neoplasm and myelodysplastic syndrome (mixed MPN/MDS) with 100% penetrance. Their study implies that human hematologic cancers may result from overdosage of X, either from Xist loss on Xi or from duplication of Xa. And they proposed that carcinogenesis is driven by a series of changes occurring in the HSC and further accumulated in mature hematopoietic cells. These changes are initiated by loss of Xist, which leads to progressive X reactivation, which in turn induces a cascade of unfavorable genome-wide changes that include dysregulation of genes involved in DNA replication, chromosome segregation, cell-cycle checkpoints, and hematopoiesis. A failure of HSC maturation and loss of long-term HSC in the marrow progressively shift hematopoiesis to extramedullary sites resulting in extra medullary hematopoiesis (EMH), thereby causally linking the X chromosome to cancer in mice. Thus, they concluded that Xist RNA not only is required to maintain XCI but also suppresses cancer in vivo. Indeed, the emerging role of aberrant gene dosage in diseases, whether of the X chromosome or for autosomes, brings with it the possible application of drugs that impact on epigenetic regulators in potential therapeutic strategies. To date, there are no published studies on human about Xist gene and its relationship with the immunophenotyping in AML patients. So, this will be the first study designed to explain its unexplored pathway in AML and detect its prognostic role and immunophenotypic association.

This international observational study aims at examining the patterns of health-related quality of life differences between long-term acute myeloid leukemia patients and their healthy peers from the general population.

Immunotherapy is a promising therapeutic approach for patients with cancers. Patients with acute lymphoblastic leukemia (ALL) experiencing early relapse less than 18 months from diagnosis had very poor prognosis with 5-year survival rate of 21% (1). Recent clinical trials demonstrated that infusions of autologous T cell modified with chimeric antigen receptors (CARs) induced durable complete remissions in patients with relapse or refractory B-cell ALL (2-4). The editors of Science Journal announced cancer immunotherapy as the breakthrough of the year for 2013 (5). On Jan 30, 2015, Dr. Steven M. Altschuler, chief executive officer of the Children's Hospital of Philadelphia and 9-year-old ALL patient Emily Whitehead with 3-year leukemia free after CAR-T cell infusion were invited to White House for President Barack Obama's announcement of the Precision Medicine Initiative. The MIT Technology Review announced that the top one breakthrough technology in 2016 is genetically engineered immune cells saving the lives of cancer patients. This project will focus on the manufacturing of clinical-grade anti-CD19 CARs for B-cell malignancies in the future clinical trials.

The purpose of this study is to describe the incidence, clinic characteristics, biological and suvirval in Lymphoblastic Leukemia patients in Mexico City reference hospitals.

The objective of this study is to evaluate the prognostic factors of acute leukemia patients and to invent the molecular genetic test for sensitive detection of minimal residual disease, and thereby this study would contribute to plan the risk adapted treatment. Patients will have samples of blood and/or bone marrow collected during diagnosis process, treatment and/or thereafter

Core binding factor (CBF) positive acute myeloid leukemia (AML) consist of 15% of patients in overall AML, expected to harbor a favorable prognosis. However, around a half of cases relapses. Accordingly, more sophisticated classification in CBF positive AMLs is essential to achieve further improvement in the treatment outcome. The current study is designed to evaluate CBF positive AML patients with genome-wide SNP array and KIT mutation study in CBF positive AML patients diagnosed at the Samsung Medical Center and Hwasun Chonnam National University Hospital, Korea between 1994 and 2008. Construction of the CBF positive AML patient cohort: clinical database establishment (including treatment outcomes and prognosis) and extraction/storage of tumor cell DNAs from marrow samples, then processing of Affymetrix SNP array 6.0. Construction of prognostic predictive model using pharmacogenomics with the results of genotypes and copy number variations (CNVs). Detection of hidden microscopic cytogenetic lesions with SNP array technique, and correlation with clinical outcomes in CBF positive AML. Detection of KIT, FLT3/ITD, and NPM1 gene mutation and its correlation with clinical outcomes in CBF positive AML. The current study attempts to analyze genetic data of core binding factor (CBF) positive acute myeloid leukemia (AML) using genome wide SNP array technique with tumor DNAs collected at the time of diagnosis. To detect microcytogenetic lesions and will analyze its prognostic significance To analyze genome-wide genotypes and copy number variations (CNVs) using pharmacogenetic approach and will construct a prognostic predictive model To detect KIT, FLT3/ITD and NPM1 mutation and evaluate its prognostic significance. The present study will establish individualized therapy for CBF positive AML, will provide a basis for molecular marker guided clinical trial in CBF positive AML.

In malignant or neoplastic disease, angiogenesis is defined as the generation of new capillaries from preexisting blood vessels, e.g. by sprouting or by intusseption. Through the pioneering work of Folkman, it was recognized that angiogenesis plays an important role in tumor development, progression, and metastasis. It is also conceivable that there are forms or developmental stages of leukemia, multiple myeloma, or lymphomas that will progress independently of angiogenesis. Synthesis of angiogenesis activators, such as vascular endothelial growth factor (VEGF) and other angiogenic factors, such as basic fibroblast growth factor (bFGF), has been demonstrated for leukemia cells, non-Hodgkin's lymphoma, and myeloma cells. Microvessel density is also significantly elevated over normal controls with progressive increases according to the stages of myelodysplastic syndrome. Increased microvessel density (MVD) in the bone marrow was found in patients with multiple myeloma in comparison to normal controls and increased MVD is an adverse prognostic marker in multiple myeloma. However, the functional status of the blood vessel (e.g. permeability) cannot be determined by the above mentioned methods.

Clinical presentation and management of Mixed-Phenotype Acute leukemia (MPAL) is heterogeneous. This descriptive observationnal study aims to review MPAL cases in the East of France based on a 10-year multicentre retrospective collection.

CAR T cells targeting CD19 have been approved for patients with relapsed or refractory ALL, failing two or more prior protocols. Several institutional-based studies with other CAR T cells targeting CD19 have demonstrated outstanding response rates in patients with refractory disease, and the ability of CAR T cells to clear CNS leukemia. Nevertheless, these cases are sparse and have never been reported collectively. Here, we aim to retrospectively assess toxicity and long term outcome of patients treated with CAR T cells for CNS relapse of ALL.
