Outcome Measures

Primary Outcomes (3)

  • Change in Urinary Glycosaminoglycan (GAG) Excretion

    Change in urinary glycosaminoglycan (GAG) excretion from baseline to 2 years

    Baseline and 2 years

  • Change in Distance Traveled

    Change in distance traveled in 6 minute walk and standard tests of range of motion and mobility. Improvement in distance walked from the start to study to end of the study is reported

    Baseline and 2 years

  • Change in Neurocognitive Ability

    Subjects will undergo full neuropsychological testing annually and abbreviated testing for attention and adaptive skills at the six-month interval visits

    Baseline and 2 years

Secondary Outcomes (2)

  • Number of Participants With Development of Neutralizing Antibodies to Naglazyme Therapy

    6 months

  • Number of Participants With Development of Neutralizing Antibodies to Naglazyme Therapy

    2 years

Study Arms (1)

Naglazyme®

EXPERIMENTAL

weekly Naglazyme® infusion for 2 years

Drug: Naglazyme®

Interventions
