Filter by:The different mechanisms of action between Antithymocyte globulin and cyclosporine can improve the effectivity when both are used in combination in patients with myelodysplastic syndrome.
Association group of therapeutic specialities authorized in a remission induction treatment(FLAG-IDA: fludarabine, cytarabine, G-CSF (lenograstim) and idarubicin) and an intensive postremission treatment with authorized therapeutic association specialities and with/without Autologous Hemopoietic Stem Cell Transplantation or Bone Marrow Transplantation in Patients With High Risk Myelodysplastic Syndromes or Secondary Acute Myeloblastic Leukemia.
This registry is a prospective, multi-center, observational study compiling data on the natural history and management of patients receiving Vidaza, and will provide unique insights into the management of myelodysplastic syndromes (MDS) and other hematological disorders and the impact of these disorders on patients.
The purpose of this study is to investigate the effects of iron chelation using deferasirox in low and INT-1 risk (referring to the international prognostic scoring system, IPSS) MDS patients who show signs of iron overload due to repeated blood transfusions. This trial is not recruiting patients in the United States.
This study is to evaluate the safety and tolerability of vorinostat in combination with decitabine as well as the in vivo molecular and biological effects of vorinostat in patients with refractory or relapsed Acute Myelogenous Leukemia (AML) and intermediate or high risk as defined by International Prognostic Scoring System (IPSS) Myelodysplastic Syndrome (MDS). Participants with Acute Myelogenous Leukemia or Myelodysplastic Syndrome are eligible.
Objectives: Primary: 1. To establish the feasibility of delayed infusion of ex vivo anergized donor peripheral blood mononuclear cells (PBMC) after CD34 selected megadose haploidentical hematopoietic stem cell transplant (HSCT) Determine the feasibility of collecting parental allogeneic stimulator cells to induce anergy to the non-shared donor:recipient haplotype Determine the feasibility of collecting donor PBMC as a source of T cells for ex vivo anergization Determine the number of transplanted individuals who meet the criteria for proceeding to delayed infusion of ex vivo anergized donor PBMC 2. To establish the safety of delayed infusion of ex vivo anergized donor PBMC by establishing the maximal number of donor T cells that can be infused without unacceptable graft-versus-host disease (GVHD) Secondary: 1. To evaluate in vitro the induction and specificity of alloantigen hyporesponsiveness in donor PBMC after ex vivo anergization 2. To assess in vitro the function of immune cells engrafted in the recipient To assess in vitro whether alloantigen hyporesponsive donor T cells are present in the recipient after HSCT To develop preliminary in vitro data on the extent of pathogen-specific immunity and its rate of recovery To describe the patterns of opportunistic infections in patients so treated
This phase II trial is studying how well cediranib maleate works in treating patients with relapsed, refractory, or untreated acute myeloid leukemia or high-risk myelodysplastic syndrome. Cediranib maleate may stop the growth of cancer cells by blocking some of the enzymes needed for cell growth and by blocking blood flow to the cancer.
The goal of this clinical research study is to learn if using a combination of fludarabine, busulfan, and antithymocyte globulin (ATG) can help to control myelofibrosis or myelodysplastic syndrome in patients receiving a bone marrow or blood stem cell transplant. The safety of these drugs will also be studied.
This is an open label extension study of romiplostim for treatment of thrombocytopenia (platelet count ≤ 50 x 10^9/L) in MDS subjects. The study is designed to assess the long-term safety of treatment with romiplostim, as measured by incidence of overall adverse events, the incidence of bleeding events, the utilization of platelet transfusions, and the duration of platelet response. The study will further describe the time to disease progression to acute myeloid leukemia (AML) and survival.
The purpose of this study is to determine the efficacy and safety of transplanting StemEx® in patients with certain hematological malignancies. For these patients, it is suggested that StemEx® can improve upon the outcome of transplanting a single, unmanipulated cord blood unit by significantly increasing the number of stem/progenitor cells available to the patient.
