OTL-200 in Patients With Late Juvenile Metachromatic Leukodystrophy (MLD)
Lysosomal Storage DiseasesMetachromatic LeukodystrophyOTL-200 is a cryopreserved dispersion for infusion containing autologous CD34+ cell enriched population that contains haematopoietic stem and progenitor cells (HSPC) transduced ex vivo using a lentiviral vector encoding the human arylsulfatase A (ARSA) gene. MLD is an autosomal recessive lysosomal storage disorder (LSD) characterized by severe and progressive demyelination affecting the central and peripheral nervous system. The aim of this clinical study is to assess the pharmacodynamic effect and long-term clinical efficacy and safety of OTL-200 in Late Juvenile MLD patients.
A Gene Transfer Study for Late-Onset Pompe Disease (RESOLUTE)
Pompe DiseasePompe Disease (Late-onset)5 moreThe purpose of this study is to evaluate the safety, tolerability, and efficacy of a single intravenous infusion of SPK-3006 in adults with clinically moderate, late-onset Pompe disease receiving enzyme replacement therapy (ERT). Participants will be treated in sequential, dose-level cohorts.
A Safety and Efficacy Study of Cryopreserved OTL-200 for Treatment of Metachromatic Leukodystrophy...
Lysosomal Storage DiseaseMetachromatic LeukodystrophyOTL-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.
Stem Cell Gene Therapy for Cystinosis
Lysosomal Storage DiseasesCystinosisThis study is a Phase 1/2 clinical trial that will assess the safety and efficacy of enriched gene-corrected hematopoietic stem cells isolated from patients affected with cystinosis. (Investigational Product: CTNS-RD-04 or CTNS-RD-04-LB, where the suffix "-LB" stands for LentiBOOST)
Gene Therapy for Metachromatic Leukodystrophy (MLD)
Lysosomal Storage DiseaseMetachromatic LeukodystrophyThis 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.
A Pilot Study for Systematic Neonatal Screening for Lysosomal Storage Diseases Using Tandem Mass...
Neonatal ScreeningLysosomal Storage DiseasesThe study will include all newborns in Normandie region for 3 years (about 105,000 births) for whom signed consent by one (or two) parents will be collected. Based on our previous pilot study (2011) assessing MCAD and PKU using tandem mass spectrometry-based method in Normandie region in which informed consents have been signed for all newborns (43,000) but we are expecting a great willingness to participate to this project. Thus, we are aiming to include 100,000 newborns, and the study will be continued until we reach at least this target. The primary objective is to evaluate the epidemiology of MPS1 and Pompe disease using dried blood samples in the first cohort of neonates tested in France (Normandie region).
Registry of Patients Diagnosed With Lysosomal Storage Diseases
Mucopolysaccharidosis IMucopolysaccharidosis II6 moreThis is an international prospective and retrospective registry of patients with Lysosomal Storage Diseases (LSDs) to understand the natural history of the disease and the outcomes of fetal therapies, with the overall goal of improving the prenatal management of patients with LSDs.
A Long Term Follow-Up Study of Fabry Disease Subjects Treated With FLT190
Fabry DiseaseLysosomal Storage DiseasesFabry disease is a rare, X-linked inborn error of glycosphingolipid metabolism caused by an abnormal gene encoding the α-galactosidase A (αGLA) enzyme. The αGLA enzyme is ubiquitously expressed throughout the body and is responsible for the breakdown of glycosphingolipids, deficiency of which results in the accumulation of specific glycosphingolipids that are associated with the pathophysiology of the disease. Current treatment for Fabry disease is limited to the symptomatic management of pain, conventional management of complications, and methods to increase the availability of functional αGLA. This clinical study aims to investigate the long-term safety and durability of αGLA in patients who have been dosed with a new gene therapy product (FLT190) in earlier clinical studies.
Genetic Studies of Lysosomal Storage Disorders
Lysosomal Storage DisordersGaucher Disease1 moreThe purpose of this study is to identify genetic, biochemical, and clinical factors that are associated with disease severity in people with Gaucher disease and other lysosomal storage disorders. There is a vast spectrum of clinical manifestations in people with Gaucher disease as well as other lysosomal storage disorders. This study will evaluate patients with lysosomal disorders on an outpatient or inpatient basis in order to better characterize the clinical, genetic, and pathophysiological features of these disorders. Participants will be re-evaluated on an annual basis.
Study of Inborn Errors of Cholesterol Synthesis and Related Disorders
Lysosomal Storage DiseaseCholesterol MetabolismThis 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.
