  • 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 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.

  • Determine the Efficacy and Safety of DNL310 vs Idursulfase in Pediatric Participants With Neuronopathic (nMPS II) or Non-Neuronopathic Mucopolysaccharidosis Type II (nnMPS II)

    open to eligible people ages 2-16

    This is a Phase 2/3, multiregional, two-arm, double-blind, randomized, active (standard-of-care)-controlled study of the efficacy and safety of DNL310, an investigational central nervous system (CNS)-penetrant enzyme-replacement therapy (ERT) for mucopolysaccharidosis type II (MPS II). Participants may also qualify to enter an open-label treatment phase with DNL310 or idursulfase based on pre-specified criteria.

  • CAMPSIITE™ RGX-121 Gene Therapy in Subjects With MPS II (Hunter Syndrome)

    open to eligible males ages 4 months to 5 years

    RGX-121 is a gene therapy which is intended to deliver a functional copy of the iduronate-2-sulfatase gene (IDS) to the central nervous system. This study is a safety and efficacy, dose ranging study to determine whether RGX-121 is safe, effective and well-tolerated by patients with MPS II.

  • In Utero Enzyme Replacement Therapy for Lysosomal Storage Diseases

    open to eligible females ages 18-50

    The investigators aims to determine the the maternal and fetal safety and feasibility of in utero fetal enzyme replacement therapy in fetuses with Lysosomal Storage Diseases.

  • 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.

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

    Sorry, not currently recruiting here

    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).

  • RGX-121 Gene Therapy in Children 5 Years of Age and Over With MPS II (Hunter Syndrome)

    Sorry, in progress, not accepting new patients

    RGX-121 is a gene therapy which is designed to deliver a functional copy of the iduronate-2-sulfatase (IDS) gene to the central nervous system. This study is a phase I/II study to determine whether RGX-121 is safe, well tolerated, and potentially effective in children five years of age and over who have severe MPS II.

  • Long Term Safety and Clinical Outcomes of Idursulfase IT and Elaprase Treatment in Pediatric Participants Who Have Completed Study HGT-HIT-094

    Sorry, in progress, not accepting new patients

    This extension study will allow participants that completed Study HGT-HIT-094 to continue receiving Elaprase treatment in conjunction with idursulfase IT or to continue receiving Elaprase treatment and begin concurrent IT treatment for those that did not receive idursulfase IT treatment in Study HGT-HIT-094.

  • Potential Treatment-Responsive Biomarkers and Clinical Outcomes in Hunter Syndrome

    Sorry, in progress, not accepting new patients

    This is a four-part prospective, multicenter, multiregional observational study of patients with mucopolysaccharidosis type II (MPS II), also known as Hunter syndrome, to assess biomarkers potentially related to disease severity and/or treatment response and prospectively assess the progression of disease in participants with MPS II who are aged 2 through 10 years (Part 1), 2 through 30 years (Part 2), < 8 years (Part 3), and 6 to < 17 years (Part 4) at the time of enrollment.
