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.
Mucopolysaccharidosis Type II (MPS II)
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.
Mucopolysaccharidosis Type II (MPS II)
Hunter syndrome (Mucopolysaccharidosis II, \[MPS II\]) is a rare, genetically linked lysosomal storage disease (LSD) caused by deficiency of the enzyme, iduronate-2-sulfatase (I2S). Most MPS II patients will present with some degree of neurodevelopmental involvement, ranging from severe cognitive impairment and behavioral problems to mildly impaired cognition. This is an observational study; no investigational treatment will be administered. The primary objective of this study is to evaluate the neurodevelopmental status of pediatric patients with MPS II over time and to gain information to guide future treatment studies in this patient population.

This is a multiregional open-label extension (OLE) to assess the safety, tolerability, and efficacy of long-term treatment with tividenofusp alfa (DNL310), an investigational central nervous system (CNS)-penetrant intravenous (IV) enzyme replacement therapy (ERT) for Hunter syndrome (MPS II). Participants who complete at least through the Week 49 visit in Study DNLI-E-0002 and do not discontinue study intervention early and participants who complete Study DNLI-E-0007 will be enrolled in this OLE. All participants will receive DNL310 for up to 5 years from the time of entry in this OLE. Participants, site staff, and the Sponsor will remain blinded to the original treatment assignment for participants entering this OLE from Study DNLI-E-0007.
Mucopolysaccharidosis II
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).

Hunter Syndrome
Elaprase (idursulfase), a large molecular protein, is not expected to cross the blood brain barrier at therapeutic levels when administered intravenously. A new formulation of idursulfase, idursulfase-IT, that differs from that of the intravenous (IV) formulation, Elaprase, has been developed to be suitable for delivery into the cerebrospinal fluid (CSF) via intrathecal administration. This Phase I/II study is designed to obtain necessary safety and exposure data, as well as secondary and exploratory outcome measures, to be interpreted and used in the design of subsequent clinical trials.
Hunter Syndrome
The objective of this study is to evaluate the effect of anti-idursulfase antibodies on idursulfase safety (measured by infusion related adverse events) between patients who develop anti-idursulfase antibodies and patients who do not after long-term idursulfase enzyme replacement therapy (ERT).
Hunter Syndrome
Study TKT024EXT was a long-term, single-arm, open-label extension of Study TKT024, a one year Phase 2/Phase 3 registration study. The primary objective of this extension study was to collect long-term safety and clinical outcome data in Mucopolysaccharidosis II (MPS II), also known as Hunter Syndrome, from the Phase 2/Phase 3 Study TKT024. All patients enrolling into this study received weekly active treatment with idursulfase, the primary dosing regimen investigated in Study TKT024. Hunter Syndrome is an X-linked recessive lysosomal storage disease caused by a deficiency of iduronate-2-sulfatase, an enzyme required to catabolize glycosaminoglycans (GAGS) in cells. As a result, GAGs accumulate in the lysosomes leading to cellular engorgement, organomegaly, tissue destruction, and organ system dysfunction. Hunter Syndrome is a rare disease with an estimated incidence of 1 in 162,000 live births.
