Filter by:OTL-200 is autologous CD34+ cells transduced with lentiviral vector containing human arylsulfatase A (ARSA) complementary deoxyribonucleic acid (cDNA) used for the treatment of MLD. MLD is an autosomal recessive lysosomal storage disorder (LSD) characterized by severe and progressive demyelination affecting the central and peripheral nervous system. This study will assess safety and efficacy of treatment using cryopreserved formulation of OTL-200 in pediatric subjects with pre-symptomatic Early Onset MLD (Late Infantile (LI) to Early Juvenile (EJ) MLD) and early symptomatic EJ MLD.
This study is designed to test the ability to achieve donor hematopoietic engraftment while maintaining low rates of transplant-related mortality (TRM) in patients with high-risk lysosomal and peroxisomal disorders using a novel conditioning regimen for hematopoietic cell transplantation (HCT). After a reduced-intensity conditioning regimen using volumetric-modulated arc therapy (VMAT)-delivered low-dose total body irradiation (TBI) with highly conformal marrow boosting, patients will be transplanted using either a related or unrelated allograft. The cell source may be marrow, peripheral blood or cord blood based on donor availability.
This Phase I/II clinical trial consists of the application of lentiviral vector-based gene therapy to patients affected by Metachromatic Leukodystrophy (MLD), a rare inherited Lysosomal Storage Disorder (LSD) resulting from mutations in the gene encoding the Arylsulfatase A (ARSA) enzyme. The medicinal product consists of autologous CD34+ hematopoietic stem/progenitor cells in which a functional ARSA cDNA is introduced by means of 3rd generation VSV-G pseudotyped lentiviral vectors.
Development of a new MS-based biomarker for the early and sensitive diagnosis of Maroteaux-Lamy disease from blood
This is a 24-month study of the use of laronidase administered into the spinal fluid to treat cognitive decline in mucopolysaccharidosis I (MPS I). MPS I is a rare genetic condition due to deficiency of the enzyme alpha-l-iduronidase. Laronidase is the manufactured form of the enzyme alpha-l-iduronidase. MPS I is a heterogeneous disease with several clinical phenotypes ranging from the most severe, Hurler syndrome, to the attenuated forms, Hurler-Scheie and Scheie. Although patients with milder forms of MPS I may not have grossly observable problems with cognition, these patients do have learning difficulties that are apparent in school and with neuropsychological testing. The goal of this study is to evaluate whether intrathecal recombinant human alpha-l-iduronidase (rhIDU) injections can stabilize or improve cognitive decline in individuals with MPS I.
This is a one-year extension study of the use of laronidase into the spinal fluid to treat spinal cord compression in mucopolysaccharidosis I. Mucopolysaccharidosis I is a rare genetic condition due to deficiency of the enzyme alpha-l-iduronidase. Spinal cord compression occurs in this condition due to accumulation of material called glycosaminoglycans (GAG). Laronidase is the manufactured form of the enzyme alpha-l-iduronidase that is deficient in mucopolysaccharidosis I patients. The aim of this study is to determine whether laronidase is safe and effective when given into the spinal fluid as a potential non-surgical treatment for spinal cord compression due to mucopolysaccharidosis I disease.

The primary objective is to determine the feasibility of attaining acceptable rates of donor cell engraftment (>25% donor chimerism at 180 days) following reduced intensity conditioning (RIC) regimens in pediatric patients < 21 years receiving cord blood transplantation for non-malignant disorders.
This study will investigate the cause and medical problems associated with a group of genetic disorders known as inborn errors of cholesterol synthesis, in which the body does not produce cholesterol. People with this disorder may have birth defects and learning and behavioral problems. People with an inborn error of cholesterol synthesis and related disorders, including Smith-Lemli-Opitz syndrome, lathosterolosis, desmosterolosis, X-linked dominant chondrodysplasia, CHILD syndrome, Greenberg dysplasia, and some cases of Antley-Bixler syndrome, may be eligible for this study. People who are carriers of the disorders also may enroll. Participants and family members will provide blood and urine samples, as well as other tissue samples collected during medically indicated procedures such as biopsy or surgery. These tissues may include, for example, gallstones, cataracts, cerebrospinal fluid, amniotic fluid, lymph tissue, and DNA samples. In rare instances, a skin biopsy may be requested to aid in establishing a diagnosis. Medical information will also be gathered from medical records, photographs, and X-rays.
Transcranial Magnetic Stimulation (TMS) is a non-invasive technique to gather information about brain function. It is very useful when studying the areas of the brain related to motor activity (motor cortex, corticospinal tract, spinal cord and nerve roots). The procedure is conducted by transmitting a magnetic signal into the brain to stimulate an area of the body. Electrodes (small pieces of metal taped to areas of the body) are used in order to measure electrical activity. A magnetic signal is sent from a metal instrument held close to the patient's head, to an area of the brain responsible for motor activity of a certain area of the body. The electrodes pick up and record the electrical activity in the muscles. This study will employ the use of TMS to diagnose neurological disorders that affect the motor cortex or the corticospinal tract. Normal subjects are sometimes studied to investigate normal activity of the nervous system and to train doctors in clinical neurophysiology and electrodiagnostic medicine at the National Institutes of Health (NIH).
Leukodystrophy is a disease of the white matter of the brain. White matter is the portion of the brain responsible for conducting electrical impulses from one area of the brain to the other. Insulating cells called myelin cover the brain and nerve cells in the white matter. If myelin becomes damaged electrical information cannot be transferred properly. Many patients suffering from leukodystrophies do not fit the description of any of the defined types of leukodystrophies and are therefore considered to have a leukodystrophy of unknown cause. The purpose of this study is to define groups of patients with leukodystrophies and to work toward finding the cause of the disorders. In order to do this, researchers will analyze patients with leukodystrophies of unknown causes. Patients will undergo clinical, neurophysiologic, biochemical, and genetic examinations and tests. Researchers believe that by studying these patients and their disorders they will be able to better understand the causes of myelin destruction, and eventually lead to effective treatments for these disorders.
