Modeling Macrophages Activation Pattern in X-linked Adrenoleukodystrophy, Metachromatic Leukodystrophy...
AdrenoleukodystrophyAdrenomyeloneuropathy2 moreThis study is a national, non-randomized, open-label, multi-site with minimal risk study in adult with adrenomyeloneuropathy (AMN), childhood and adult subjects with cerebral ALD (cALD), juvenile/adult metachromatic leukodystrophy (MLD) and adults with leukoencephalopathy and axonal spheroids and pigmented glia (ALSP). 49 subjects will be enrolled with one blood sample collection during one of their medical follow-up visit. This trial will evaluate the role of innate immunity to influence disease progression in X-ALD, MLD and ALSP, and if the mutations related to these leukodystrophies result in a specific immune response leading to the pathogenesis.
The Myelin Disorders Biorepository Project
LeukodystrophyWhite Matter Disease20 moreThe Myelin Disorders Biorepository Project (MDBP) seeks to collect and analyze clinical data and biological samples from leukodystrophy patients worldwide to support ongoing and future research projects. The MDBP is one of the world's largest leukodystrophy biorepositories, having enrolled nearly 2,000 affected individuals since it was launched over a decade ago. Researchers working in the biorepository hope to use these materials to uncover new genetic etiologies for various leukodystrophies, develop biomarkers for use in future clinical trials, and better understand the natural history of these disorders. The knowledge gained from these efforts may help improve the diagnostic tools and treatment options available to patients in the future.
ScreenPlus: A Comprehensive, Flexible, Multi-disorder Newborn Screening Program
Acid Sphingomyelinase DeficiencyCeroid Lipofuscinosis15 moreScreenPlus is a consented, multi-disorder pilot newborn screening program implemented in conjunction with the New York State Newborn Screening Program that provides families the option to have their newborn(s) screened for a panel of additional conditions. The study has three primary objectives: 1) define the analytic and clinical validity of multi-tiered screening assays for a flexible panel of disorders, 2) determine disease incidence in an ethnically diverse population, and 3) assess the impact of early diagnosis on health outcomes. Over a five-year period, ScreenPlus aims to screen 175,000 infants born in nine high birthrate, ethnically diverse pilot hospitals in New York for a flexible panel of 14 rare genetic disorders. This study will also involve an evaluation of the Ethical, Legal and Social issues pertaining to NBS for complex disorders, which will be done via online surveys that will be directed towards ScreenPlus parents who opt to participate and qualitative interviews with families of infants who are identified through ScreenPlus.
Phase I/II Pilot Study of Mixed Chimerism to Treat Inherited Metabolic Disorders
Hurler Syndrome (MPS I)Hurler-Scheie Syndrome10 moreThe goal of this research study is to establish chimerism and avoid graft-versus-host-disease (GVHD) in patients with inherited metabolic disorders.
The Natural History of Metachromatic Leukodystrophy Study (HOME Study)
Metachromatic LeukodystrophyThe primary aims of the HOME Study are to: Design and implement a natural history study for metachromatic leukodystrophy to serve as a source of external control data, to augment or replace concurrent controls in clinical trials; Pilot test and develop guidance on how to design, conduct, and analyze the data from a natural history study to support adaptive trial designs for regulatory use; Reduce burden of participation in trials and provide a potential solution to patient recruitment challenges, particularly for RCT's; and Design approaches that support remote participation in studies.
The Natural History of Metachromatic Leukodystrophy
Metachromatic LeukodystrophyThere have not been longitudinal studies which track patients' neurologically or developmentally in a systematic manner. By simultaneously tracking patients' neurodevelopment along with neuroimaging and neurophysiologic studies it becomes much easier to draw conclusions on the differential effects of the disease process and any available treatments that patients might receive. In addition, many of the gene mutations, which cause MLD have not been linked to the age of onset or the expected disease course.
Open-Label Extension Study of Recombinant Human Arylsulfatase A (HGT-1111) in Late Infantile MLD...
Late Infantile Metachromatic LeukodystrophyThis is a multi-center, open-label, extension study of patients with late infantile MLD who have previously completed clinical study HGT-MLD-048 (NCT00633139), defined as the completion of all Week 52 procedures. This group of patients will be offered ongoing treatment with HGT-1111 in this protocol. One infusion will be given every other week until the product is commercially available, the patient discontinues, or the study is terminated by the Sponsor, provided no safety issues have emerged.
A Study to Learn About Metachromatic Leukodystrophy (MLD) in Children in Spain
Metachromatic Leukodystrophy (MLD)The main aim of this study is to learn about metachromatic leukodystrophy (MLD) in children and teenagers in Spain. This includes checking the number of new MLD cases and the frequency of children with MLD in 2022 in Spain. There is no treatment involved in this study. Participants' data will be taken from their medical records (charts), which were already collected as a part of their routine care between 01 January 2000 and 31 December 2022.
Efficacy METAZYM for the Treatment Metachromatic Leukodystrophy Treated With Hematopoietic Stem...
Metachromatic LeukodystrophyThere is currently no effective treatment for late infantile MLD once clinical symptoms are evident. METAZYM is a recombinant human arylsulfatase A developed for an intravenous ERT for the treatment of late infantile MLD. The overall objective of this study is to evaluate the efficacy and safety of intravenous rhASA treatment in a patient with late infantile MLD who had previously received hematopoietic stem cell transplantation (HCT).
Multicenter Study of HGT-1110 Administered Intrathecally in Children With Metachromatic Leukodystrophy...
Metachromatic Leukodystrophy (MLD)The purpose of this study is to determine the safety of ascending doses of HGT-1110 administered by intrathecal (IT) injection for 38 weeks (20 injections) in children with metachromatic leukodystrophy (MLD).
