Active clinical trials for "Preleukemia"

This phase I trial is studying the side effects of monoclonal antibody therapy in treating patients with ovarian epithelial cancer, melanoma, acute myeloid leukemia, myelodysplastic syndrome, or non-small cell lung cancer. Monoclonal antibodies can locate tumor cells and either kill them or deliver tumor-killing substances to them without harming normal cells

The study seeks to compare time from formal search to hematopoietic cell transplantation (HCT) for patients 18 years and older, randomized between haplo-cord search and matched unrelated donor (MUD) search for patients with acute myeloid leukemia (AML) and high-risk myelodysplastic syndrome (MDS)

Relapse after an allogeneic hematopoietic stem cell transplantation (HSCT) is high in patients with advanced AML, in the 50% range. NK cells have been shown to possess significant anti-leukemic activity and may be used to reduce the incidence of relapse in patients with advanced AML. Investigators hypothesize that the administration of a purified boost of NK cells on day +7 post HSCT, will reduce the incidence of relapse from the current 50% to 25%. In a phase III multicenter clinical study, 116 patients will be randomized to receive or not a boost of donor NK cells on day +7 post-HSCT. The first 10 patients in the experimental arm will be analyzed for toxicity. The stopping rule will be a transplant related mortality of more than 50% in the first 20 patients who received NK cells.

This is a Phase II, single-arm, open-label, multinational, multicenter study of rATG in patients with low or intermediate-1 risk MDS who have either failed 1 prior treatment with growth factor(s), hypomethylating agents (5-azacitidine or decitabine), or the antiangiogenic agents lenalidomide or thalidomide, or who have never been treated for MDS (i.e., treatment-naïve patients).

This is a clinical research study designed to evaluate whether the administration of a vaccine to patients after transplant consisting of a minor histocompatibility antigen (mHag peptide) mixed with G-CSF (a drug intended to stimulate the immune system) can stimulate increased graft versus leukemia (GVL) responses without causing graft-versus-host disease (GVHD).

Myelodysplastic syndromes (MDS) are clonal diseases of hematopoietic stem cells (HSC) characterized by dysplastic and inefficient hematopoiesis related to excessive progenitor cell death. Ferroptosis is a recently described cell death mechanism and we think that it could be a major player in the pathophysiology of MDS, involved in the cell death that characterizes these diseases and contributing to cytopenias. The study aims to demonstrate that there is a significant activation of this phenomenon in MDS patients compared to a population of subjects without MDS.

This study will determine the activity of decitabine, low dose cytarabine (ARA-C) and G-CSF for patients with myelodysplasia and leukemia.

This study will collect tumor samples from people with cancers of the blood, bone marrow, or lymph glands for laboratory study of the biology of these conditions. Such studies contribute to a better understanding of cancer biology and to the development of new treatments. Planned studies include: Examination of individual cancer cells and to search for differences compared to other types of cancer and normal cells Examination of the chromosomes and genes in cancer cells and to search for differences compared to other types of cancer and normal cells Development of sensitive methods to detect small amounts of cancer that remain after treatment Search for new cancer proteins that might serve as targets for treatment Investigation of methods to develop cancer vaccines. Patients from >= 1 to 75 years of age with acute lymphocytic leukemia, acute myelogenous leukemia, myelodysplastic syndrome, chronic myelogenous leukemia, juvenile myelomonocytic leukemia, non-Hodgkin's lymphoma, Hodgkin's disease, and other hematologic malignancies may be eligible for this study. Blood or bone marrow samples will be collected when sampling is required for the patient's medical care. Cells from some individuals will be grown in test tubes, establishing cell lines or in animals, establishing xenograft models. (A xenograft is transplantation of cells of one species to another species.)

The purpose of this study was to determine which of the doses of decitabine maximizes genomic demethylation in patients with Myelodysplastic Syndrome (MDS).

The goal of this Pilot-study is to evaluate the response of unselected MDS patients to temsirolimus a drug approved for the treatment of renal cell cancer. It is planned to give temsirolimus at a weekly dose of 25 mg as intravenous infusion for a maximum duration of 12 months. Regular bone marrow biopsies are planned for controlling MDS response.
