Evaluation of the long-term treatment effects of idursulfase using statistical modelling: Data from the Hunter Outcome Survey (HOS)
Treatment for mucopolysaccharidosis type II (MPS II Hunter syndrome) is available in the form of intravenous enzyme replacement therapy (ERT) with idursulfase (Shire, Lexington, MA, USA). This analysis used statistical modelling to evaluate the long-term treatment effects of idursulfase on selected clinical parameters based on data from HOS, a global, observational registry (Shire, Lexington, MA, USA). Mixed modelling was used to analyse data from male patients followed prospectively in HOS who had received idursulfase for 5-8 years and information available for two or more timepoints, of which one was pre-ERT. Data were excluded from patients with only pre-ERT information available, who ha…

Clinical outcomes in idursulfase-treated patients with MPS II: 3-year data from the Hunter Outcome Survey (HOS)
Multidisciplinary management of Hunter syndrome.
Hunter syndrome is a rare, X-linked disorder caused by a deficiency of the lysosomal enzyme iduronate-2-sulfatase. In the absence of sufficient enzyme activity, glycosaminoglycans accumulate in the lysosomes of many tissues and organs and contribute to the multisystem, progressive pathologies seen in Hunter syndrome. The nervous, cardiovascular, respiratory, and musculoskeletal systems can be involved in individuals with Hunter syndrome. Although the management of some clinical problems associated with the disease may seem routine, the management is typically complex and requires the physician to be aware of the special issues surrounding the patient with Hunter syndrome, and a multidiscipl…

PO-0096 Clinical Effectiveness Of Idursulfase In Boys Aged 0–5 Years With Hunter Syndrome: 3-year Data From The Hunter Outcome Survey
Background and aims Symptoms of Hunter syndrome typically become apparent at 2–4 years of age. Previous analyses have demonstrated improvements in certain clinical measures in young patients receiving idursulfase (Shire); however, data on long-term idursulfase use in these patients remain limited. This analysis used data available in the Hunter Outcome Survey (HOS), a global, observational registry sponsored by Shire, to investigate long-term effectiveness of idursulfase in boys with Hunter syndrome aged 0–5 years. Methods As of January 2014, 260/564 males followed prospectively in HOS had received ≥1 idursulfase infusion (excluding those who had received a bone marrow transplant or were en…
Idursulfase treatment of Hunter syndrome in children younger than 6 years: results from the Hunter Outcome Survey.
Purpose: To use the Hunter Outcome Survey, an international database, to assess the safety and effectiveness of enzyme replacement therapy with idursulfase in patients with Hunter syndrome who started treatment before 6 years of age. Methods: The study population included all patients enrolled in the Hunter Outcome Survey who started idursulfase infusions (0.5 mg/kg every other week) before 6 years of age and who had at least one follow-up examination recorded. Results: The study population included 124 patients, younger than 6 years, who had a mean age at start of idursulfase of 3.6 ± 1.6 years (mean ± SD). The mean duration of treatment was 22.9 ± 14.6 months. A total of 69 infusion-relat…
Characteristics of patients with mucopolysaccharidosis type II who have received a bone marrow transplant: Data from the Hunter Outcome Survey
Mucopolysaccharidosis type II (MPS II Hunter syndrome) is a rare, life-limiting, X-linked lysosomal storage disease. The Hunter Outcome Survey (HOS) is a Shire-sponsored, global, observational registry initiated in 2005 that collects real-world data on the natural history of MPS II and long-term treatment with enzyme replacement therapy (ERT) with idursulfase. Patients receiving other forms of pharmacological ERT are excluded from HOS but individuals who have received a bone marrow transplant (BMT) may be enrolled. This analysis examined the characteristics of 36 male patients in HOS from Europe and North America who had received a BMT (March 2018 data). In total, 22 patients (61.1%) were E…

Long-term, open-labeled extension study of idursulfase in the treatment of Hunter syndrome.
Purpose: This study evaluated the safety and effectiveness of long-term enzyme replacement therapy with idursulfase (recombinant human iduronate-2-sulfatase) in patients with Hunter syndrome. Methods: All 94 patients who completed a 53-week double-blinded study of idursulfase enrolled in this open-labeled extension study and received intravenous idursulfase at a dose of 0.5 mg/kg weekly for 2 years, and clinical outcomes and safety were assessed. Results: No change in percent predicted forced vital capacity was seen, but absolute forced vital capacity demonstrated sustained improvement and was increased 25.1% at the end of the study. Statistically significant increases in 6-minute walking t…
