  • ELAPRASE in Treatment-naïve Participants With Hunter Syndrome (Mucopolysaccharidosis [MPS] II)

    open to eligible males ages up to 6 years

    The main aim of this study is to evaluate the ability of a prophylactic immune tolerizing regimen (ITR) to prevent or reduce the development of high titer anti-idursulfase antibodies in treatment-naïve participants with Hunter syndrome. In this open label, single arm study, all participants will receive ELAPRASE treatment and a prophylactic ITR. Participants will be treated with ELAPRASE for up to 104 weeks. The prophylactic ITR will start 1 day prior to the start of ELAPRASE. The prophylactic ITR will consist of a 5-week cycle of: Rituximab (intravenously [IV], weekly for 4 weeks); Methotrexate (oral, 3 times per week for 5 weeks) and intravenous immunoglobulin (IVIG) (IV, every 4 weeks of the cycle). Following the completion of 1 cycle, an assessment will be made at Month 6, 12, and 18 regarding the need for administering another 5-week cycle of the ITR. Participants will be in the study for approximately 112 weeks (including 6 weeks for screening, up to 104 weeks for treatment, and 2 weeks for follow-up).

  • Tividenofusp Alfa (DNL310) in Pediatric Participants With Hunter Syndrome

    open to eligible males ages up to 18 years

    This is a multicenter, multiregional, open-label study to assess the safety, pharmacokinetics (PK), and pharmacodynamics (PD) of tividenofusp alfa (DNL310), an investigational central nervous system (CNS)-penetrant enzyme replacement therapy (ERT), designed to treat both the peripheral and CNS manifestations of Mucopolysaccharidosis type II (MPS II; Hunter syndrome). Participants, whose physicians feel they are deriving benefit, will have the opportunity to be reconsented into a safety extension and then an open-label extension for continued evaluation.

  • Voxzogo for Growth Deficits in MPS IVA and VI

    open to eligible people ages 5-10

    This is a Phase I/II, single arm, open label study of vosoritide therapy provided subcutaneously at 15 ug/kg/day for 48 weeks to 6 patients with MPS IVA or VI. Prior to enrollment in the interventional arm of study, subjects will be followed for a minimum of 24 weeks to gather information on safety profiles and determine annualized growth velocity. The primary study endpoint is the determination of safety and tolerability of daily vosoritide treatment in MPS. Exploratory endpoints include changes in linear and segmental growth as well as biomarkers of growth and bone metabolism.

  • Mucopolysaccharidosis I (MPS I) Registry

    open to all eligible people

    The Mucopolysaccharidosis I (MPS I) Registry is an ongoing, observational database that tracks the outcomes of patients with MPS I. The data collected by the MPS I Registry will provide information to better characterize the natural history and progression of MPS I as well as the clinical responses of patients receiving enzyme replacement therapy, such as Aldurazyme (Recombinant Human Alpha-L-Iduronidase), or other treatment modalities. The objectives of the Registry are: - To evaluate the long-term effectiveness and safety of Aldurazyme® (laronidase) - To characterize and describe the MPS I population as a whole, including the variability, progression, and natural history of MPS I - To help the MPS I medical community with the development of recommendations for monitoring patients and reports on patient outcomes to optimize patient care

  • Registry of Patients Diagnosed With Lysosomal Storage Diseases

    open to eligible people ages up to 64 years

    This 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.
