Filter by:The purpose of this clinical trial is to investigate the safety of human placental-derived stem cells (HPDSC) given in conjunction with umbilical cord blood (UCB) stem cells in patients with various malignant or nonmalignant disorders who require a stem cell transplant. Patients will get either full dose (high-intensity) or lower dose (low intensity) chemo- and immunotherapy followed by a stem cell transplantation with UCB and HPDSC.
This is a clinical trial of bone marrow transplantation for patients with the diagnosis of a genetic disease of blood cells that do not have an HLA-matched sibling donor. Genetic diseases of blood cell include: Red blood cell defects e.g. hemoglobinopathies (sickle cell disease and thalassemia), Blackfan-Diamond anemia and congenital or chronic hemolytic anemias; White blood cells defects/immune deficiencies e.g. chronic granulomatous disease, Wiskott-Aldrich syndrome,Osteopetrosis, Kostmann's syndrome (congenital neutropenia), Hereditary Lymphohistiocytosis (HLH); Platelets defects e.g.Congenital amegakaryocytic thrombocytopenia; Metabolic/storage disorders e.g. leukodystrophies,mucopolysaccharidoses as Hurler disease;Stem cell defects e.g.reticular agenesis, among many other rare similar conditions. The study treatment plan uses a new transplant treatment regimen that aims to try to decrease the acute toxicities and complications associated with the standard treatment plans and to improve outcome The blood stem cells will be derived from either unrelated donor or unrelated umbilical cord blood.
The purpose of this study is to determine the safety and engraftment of donor hematopoietic cells using this conditioning regimen in patients undergoing a hematopoietic (blood forming) cell transplant for an inherited metabolic storage disease.
The main source of energy for the brain comes from a combination of oxygen and glucose (sugar). For brain cells to function normally they must receive a constant supply of these nutrients. As areas of the brain become more active blood flow into and out of these areas increase. In addition to oxygen and glucose, the brain uses chemical compounds known as phospholipids. These phospholipids make up the covering of nerve cells that assist in the transfer of information from cell to cell. Without phospholipids brain cell activity may become abnormal and cause problems in the nervous system. Certain diseases like Alzheimer's disease and brain tumors can affect blood flow to the brain and change the way the brain metabolizes phospholipids. In addition to diseases, changes in the brain occur with normal healthy aging. This study is designed to use PET scan to measure changes in blood flow and changes in phospholipid metabolism. Using this technique, researchers can improve their understanding of how certain diseases change the shape and function of the brain.
