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).
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 objective of the phase I part of the trial is the determination of the maximum tolerated dose (MTD) of TCP (Tranylcypromine) in combination with fixed-dose ATRA (all-trans-retinoic acid) and with fixed-dose AraC (Cytarabine) and to derive the recommended phase II dose (RP2D) in patients with non-APL AML or MDS for whom no standard treatment is available or who failed azanucleoside treatment. The objective of the phase II part of the trial is a first evaluation of the efficacy of TCP at the RP2D in combination with fixed-dose ATRA and with fixed-dose AraC as basis for further investigations of TCP
The primary objectives of the trial are to assess the safety and pharmacokinetics profile of pegolsihematide for treatment of anemia patient with myelodysplastic syndromes.
