Extension Study of Intrathecal Enzyme Replacement Therapy for MPS I

Spinal Cord CompressionMucopolysaccharidosis I3 more

This is a one-year extension study of the use of laronidase into the spinal fluid to treat spinal cord compression in mucopolysaccharidosis I. Mucopolysaccharidosis I is a rare genetic condition due to deficiency of the enzyme alpha-l-iduronidase. Spinal cord compression occurs in this condition due to accumulation of material called glycosaminoglycans (GAG). Laronidase is the manufactured form of the enzyme alpha-l-iduronidase that is deficient in mucopolysaccharidosis I patients. The aim of this study is to determine whether laronidase is safe and effective when given into the spinal fluid as a potential non-surgical treatment for spinal cord compression due to mucopolysaccharidosis I disease.

Intrathecal Enzyme Replacement for Hurler Syndrome

Hurler Syndrome

This protocol will examine whether the enzyme alpha-L-iduronidase (Laronidase), delivered into the spinal fluid of patients with Hurler syndrome at intervals before and after bone marrow transplant, is a safe and effective approach to slow the neurologic degeneration seen in Hurler patients undergoing transplantation.

Administration of IV Laronidase Post Bone Marrow Transplant in Hurler

Hurler Syndrome

This is a single center pilot study in which Laronidase will be given weekly for two years in patients with Hurler syndrome, also known as mucopolysaccharide IH (MPS I, Hurler syndrome), that have previously been treated with an allogeneic transplant.

Phase 3 Extension Study of the Safety and Efficacy of Aldurazyme® (Laronidase) in Mucopolysaccharidosis...

Mucopolysaccharidosis IHurler's Syndrome2 more

This study is being conducted to collect additional long-term efficacy and safety data of Aldurazyme® (laronidase) patients with MPS I disease. Patients who were previously enrolled in the Phase 3 Double-Blind Study will be enrolled in this study.

Extension Study Evaluating Long Term Safety and Activity of AGT-181 in Children With MPS I

Mucopolysaccharidosis I

AGT-181 is a fusion protein containing alpha-L-iduronidase that is intended to deliver the enzyme peripherally and to the brain, when administered intravenously. This is a long term safety and tolerability study of AGT-181 in patients with MPS I who completed the previous 26-week study, AGT-181-101. Information on the biological activity of the investigational drug will also be collected.

China Post-marketing Surveillance (PMS) Study of Aldurazyme®

Mucopolysaccharidosis I

This is a single treatment arm study that is open-label to be conducted in Chinese participants with MPS I. Trial Objectives are to evaluate the safety and tolerability of Aldurazyme in Chinese MPS I participants, and to evaluate the efficacy of Aldurazyme on the percent change of urinary glycosaminoglycans (uGAGs) from baseline to Week 26. The study will also evaluate the effect on uGAG level and liver volume (hepatomegaly) after 26 weeks, with Aldurazyme treatment in Chinese MPS I participants. Treatment duration will include: 2 weeks of screening, 26 weeks of treatment and 1 week of follow-up period. During the treatment period, weekly visits are designed to accommodate weekly administration of Aldurazyme (laronidase).

A Study of Intrathecal Enzyme Therapy for Cognitive Decline in MPS I

Cognitive DeclineMucopolysaccharidosis I3 more

This is a 24-month study of the use of laronidase administered into the spinal fluid to treat cognitive decline in mucopolysaccharidosis I (MPS I). MPS I is a rare genetic condition due to deficiency of the enzyme alpha-l-iduronidase. Laronidase is the manufactured form of the enzyme alpha-l-iduronidase. MPS I is a heterogeneous disease with several clinical phenotypes ranging from the most severe, Hurler syndrome, to the attenuated forms, Hurler-Scheie and Scheie. Although patients with milder forms of MPS I may not have grossly observable problems with cognition, these patients do have learning difficulties that are apparent in school and with neuropsychological testing. The goal of this study is to evaluate whether intrathecal recombinant human alpha-l-iduronidase (rhIDU) injections can stabilize or improve cognitive decline in individuals with MPS I.
