Filter by:This study is being conducted to identify pediatric patients with Hunter syndrome who have neurodevelopmental disease characteristics, who are currently receiving treatment with Elaprase, and who may be suitable to participate in a clinical study with an investigational agent.
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.
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).
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.
The objective of this study is to determine the safety of once weekly dosing of idursulfase 0.5 mg/kg administered by intravenous (IV) infusion for male Hunter syndrome patients ≤ 5 years old.
