Filter by:The prospective BoHemE study is designed to evaluate the correlation between bone marrow function and skeletal health in elderly patients (>= 60 years) with or without pre-existing myelodysplastic syndromes (MDS).
The trial will be conducted as a multicentre open label, randomised prospective phase II clinical trial in patients with high risk myeloid malignancies. The primary objective is to evaluate whether prophylactic donor lymphocyte infusions (DLI) delivered as part of a planned schedule improves the disease free survival of patients with myeloid malignancies.
Allogeneic hematopoietic stem cell transplantation (allo-HSCT) appears to be an efficient tool to cure refractory anemia with excess blasts-1 (RAEB-1), refractory anemia with excess blasts-2 (RAEB-2) and acute myeloid leukemia (AML) secondary to myelodysplastic syndrome (MDS). At present, the necessity of chemotherapy pre-transplantation for RAEB-1, RAEB-2 and AML secondary to MDS (bone marrow blast cells less than 50%) undergoing allo-HSCT remains in discussion. In this study, the effects of chemotherapy and no chemotherapy pre-transplantation in patients with RAEB-1, REAB-2 and AML secondary to MDS (bone marrow blast cells less than 50%) undergoing allo-HSCT are evaluated.
The project's objective is to identify and characterize somatic mutations in cases of idiopathic cytopenia of undetermined significance (ICUS) on the basis of molecular defects found in myelodysplastic syndrome (MDS), in order to validate the hypothesis whereby ICUS may be a precursor of MDS
This study seeks to examine treatment therapy that will reduced regimen-related toxicity and relapse while promoting rapid immune reconstitution with limited serious graft-versus-host-disease (GVHD) and also improve disease-free survival and quality of life. The investigators propose to evaluate the safety and efficacy of selective naive T-cell depleted (by TCRɑβ and CD45RA depletion, respectively) haploidentical hematopoietic cell transplant (HCT) following reduced intensity conditioning regimen that avoids radiation in patients with hematologic malignancies that have relapsed or are refractory following prior allogeneic transplantation. PRIMARY OBJECTIVE: - To estimate engraftment by day +30 post-transplant in patients who receive TCRɑβ-depleted and CD45RA-depleted haploidentical donor progenitor cell transplantation following reduced intensity conditioning regimen without radiation. SECONDARY OBJECTIVES: - Assess the safety and feasibility of the addition of Blinatumomab in the early post-engraftment period in patients with CD19+ malignancy. - Estimate the incidence of malignant relapse, event-free survival, and overall survival at one-year post-transplantation. - Estimate incidence and severity of acute and chronic (GVHD). - Estimate the rate of transplant related mortality (TRM) in the first 100 days after transplantation.
MDS are a diverse group of hematopoietic malignancies, which mainly occur in patients over 75 years of age. Incidence rate in 2012 in France was more than 6 cases per 100 000 person-years. MDS are characterized by ineffective haematopoiesis causing cytopenia, and by leukemic transformation. The disease is heterogeneous, its pathophysiology complex and clinical evolution variable.The few data available on MDS patients show how difficult it is to understand MDS, its prognosis and the reasons for prescribing or not some treatments. In the context of a highly complex potentially lethal disease such as MDS, it is of utmost importance to optimize the information conveyed to patients. Particularly, 70.5% of MDS patients surveyed in our developmental study would have preferred more information about prognosis at diagnosis disclosure. A simple intervention based on the use of a question prompt list (QPL), would greatly improve the information process by helping patients to express their main concerns at their medical consultations. Cultural differences may exist in the appraisal of QPLs and QPLs have not yet been widely used in France. However, in line with the previous results available in the literature and in a context a priori favourable to the use of such an instrument, the investigators hypothesise that use of a QPL will increase MDS patients' expressions of concerns and questions at their medical consultations. Particularly the investigators assume that the discussion about prognosis will be facilitated, without increasing anxiety because patients remain free to ask or not for such information. The use of QPLs would also be a way to limit social inequalities related to insufficient information and to encourage patient-doctor communication and meeting of patient preferences which could lead to better health outcomes.
To evaluate the safety and clinical efficacy of ultra-low-dose decitabine in Chinese MDS
Multi-center study enrolling patients suspected or newly diagnosed with myelodysplastic syndromes (MDS), myelodysplastic syndromes/myeloproliferative neoplasms (MDS/MPN) overlap disorder, or idiopathic cytopenia of undetermined significance (ICUS). Participants will be followed long term. Clinical data, blood, and tissue samples will be collected to establish a biorepository to facilitate the study of the natural history of MDS.
This phase II clinical trial studies how well personalized natural killer (NK) cell therapy works after chemotherapy and umbilical cord blood transplant in treating patients with myelodysplastic syndrome, leukemia, lymphoma or multiple myeloma. This clinical trial will test cord blood (CB) selection for human leukocyte antigen (HLA)-C1/x recipients based on HLA-killer-cell immunoglobulin-like receptor (KIR) typing, and adoptive therapy with CB-derived NK cells for HLA-C2/C2 patients. Natural killer cells may kill tumor cells that remain in the body after chemotherapy treatment and lessen the risk of graft versus host disease after cord blood transplant.
The purpose of this study is to collect and store samples and health information for current and future research to learn more about the causes and treatment of blood diseases. This is not a therapeutic or diagnostic protocol for clinical purposes. Blood, bone marrow, hair follicles, nail clippings, urine, saliva and buccal swabs, left over tissue, as well as health information will be used to study and learn about blood diseases by using genetic and/or genomic research. In general, genetic research studies specific genes of an individual; genomic research studies the complete genetic makeup of an individual. It is not known why many people have blood diseases, because not all genes causing these diseases have been found. It is also not known why some people with the same disease are sicker than others, but this may be related to their genes. By studying the genomes in individuals with blood diseases and their family members, the investigators hope to learn more about how diseases develop and respond to treatment which may provide new and better ways to diagnose and treat blood diseases. Primary Objective: - Establish a repository of DNA and cryopreserved blood cells with linked clinical information from individuals with non-malignant blood diseases and biologically-related family members, in conjunction with the existing St. Jude biorepository, to conduct genomic and functional studies to facilitate secondary objectives. Secondary Objectives: - Utilize next generation genomic sequencing technologies to Identify novel genetic alternations that associate with disease status in individuals with unexplained non-malignant blood diseases. - Use genomic approaches to identify modifier genes in individuals with defined monogenic non-malignant blood diseases. - Use genomic approaches to identify genetic variants associated with treatment outcomes and toxicities for individuals with non-malignant blood disease. - Use single cell genomics, transcriptomics, proteomics and metabolomics to investigate biomarkers for disease progression, sickle cell disease (SCD) pain events and the long-term cellular and molecular effects of hydroxyurea therapy. - Using longitudinal assessment of clinical and genetic, study the long-term outcomes and evolving genetic changes in non-malignant blood diseases. Exploratory Objectives - Determine whether analysis of select patient-derived bone marrow hematopoietic progenitor/stem (HSPC) cells or induced pluripotent stem (iPS) cells can recapitulate genotype-phenotype relationships and provide insight into disease mechanisms. - Determine whether analysis of circulating mature blood cells and their progenitors from selected patients with suspected or proven genetic hematological disorders can recapitulate genotype-phenotype relationships and provide insight into disease mechanisms.
