Primary Outcome Measures:
  • Change in Height [ Time Frame: 52 weeks ]
  • Change in Weight [ Time Frame: 52 weeks ]
  • Change in Haed Circumference [ Time Frame: 52 weeks ]

Secondary Outcome Measures:
  • Change in Urinary Glycosaminoglycan Levels [ Time Frame: minimum 52 weeks of dosing ]

Detailed Description:

The primary objective of the study was to evaluate the efficacy of two dose levels of Naglazyme in preventing the progression of skeletal dysplasia in infants under the age of one year who have MPS VI by monitoring physical appearance, x-ray of the skeletal system and growth.

The secondary objective of the study was to evaluate the efficacy of the two dose levels of Naglazyme in preventing several measures of disease progression in infants under the age of one year who have MPS VI by monitoring urinary GAGs, gross and fine motor function, cardiac function, vision, hearing, and use of health resources.

The safety objective of the study was to evaluate the safety of two dose levels of Naglazyme in infants under the age of one year who have MPS VI.

  • Parent or legal guardian willing and able to comply with all study procedures
  • Equal to or greater than 36 weeks estimated gestational age by physical exam at birth
