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.
This is a multi-center, open label, study conducted to evaluate the safety of laronidase administered by intravenous drip infusion in Japanese patients with MPS I disease. Following baseline evaluation, patients will receive weekly infusions of JC0498 at an intravenous dose of 100 units/kg. Patient safety will be monitored continuously throughout the trial. In addition, the effects of JC0498 treatment in this patient population will be assessed by periodically evaluating aspects of MPS I disease in patients at scheduled intervals over the duration of the trial. Since patients may be eligible for the trial if they have received JC0498, a portion of the data may be captured retrospectively and recorded onto the case report forms (CRFs). This study represents the first good clinical practice (GCP) effort to characterize MPS I in the Japanese population and evaluate the effects of JC0498 on disease manifestations.
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.
The main objectives of this study are to evaluate the safety and pharmacokinetics (PK) of enzyme replacement therapy with recombinant human alpha-L-iduronidase [Aldurazyme® (laronidase)] in mucopolysaccharidosis I (MPS I) patients less than 5 years old. Efficacy measurements will also be evaluated in this study.
The main purpose of this study is to evaluate differences in the pharmacodynamic response of 4 Aldurazyme® (laronidase) dose regimens in patients with Mucopolysaccharidosis I (MPS I).
The purpose of this study is to determine whether the development of antibodies to laronidase in patients with MPS I receiving Aldurazyme® impairs the clearance of GAG substrate.
