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).

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

Sorry, in progress, not accepting new patients
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.

Cannabidiol in Sanfilippo Syndrome
Sorry, not yet accepting patients
The goal of this clinical trial is to test cannabidiol in Sanfilippo syndrome. The main questions it aims to answer are: 1) determine the safety of cannabidiol in Sanfilippo syndrome, and 2) explore the efficacy of cannabidiol in treating the neurobehavioral symptoms and functional outcomes of Sanfilippo syndrome. Each participant's caregiver will be asked to complete surveys related to the participant's behavior, mood, sleep, stooling, pain, and caregiver stress intermittently throughout the study. All participants will be enrolled into one of two cohorts based on enrollment order: 1. Sentinel Safety Cohort (first 5 participants) - all participants treated with Epidiolex (cannabidiol) 2. Controlled Cohort (next 30 participants) - participants randomized 1:1 (equal chance) to start treatment with Epidiolex (cannabidiol) or placebo for 16 weeks, followed by an 8-week washout period (no treatment). Participants then switch to the opposite treatment group for 16 weeks followed by all participants treated for 52 weeks with Epidiolex (cannabidiol).
