Study Description
Brief Summary:
Pompe disease (also known as glycogen storage disease Type II) is caused by a deficiency of a critical enzyme in the body called acid alpha-glucosidase (GAA). Normally, GAA is used by the body's cells to break down glycogen (a stored form of sugar) within specialized structures called lysosomes. In patients with Pompe disease, an excessive amount of glycogen accumulates and is stored in various tissues, especially heart and skeletal muscle, which prevents their normal function. The overall objective of this study is to evaluate the long-term growth and development of patients with infantile-onset Pompe disease with alglucosidase alfa before 1 year of age. Patients will be followed for 10-year period.

Outcome Measures

Primary Outcome Measures :
  1. Long-term growth and development as measured by recumbent length/height, weight and head circumference [ Time Frame: Every 3 Months for up to 10 years ]
  2. Change from baseline in motor development and function, as measured by changes in the motor subscale of the Bayley Scales of Infant and Toddler Development (Bayley-III) (up to 42 months of age) at 10 years [ Time Frame: Up to 10 years ]
  3. Change from baseline in motor development and function, as measured by changes in the total score of the Gross Motor Function Measure (GMFM-88) at 10 years [ Time Frame: Up to 10 years ]
  4. Change from baseline in the raw scores, normative standard scores and scaled scores for the Functional Skills Mobility and Self-Care domains of the Pompe Pediatric Evaluation of Disability Inventory (Pompe PEDI) at 10 years [ Time Frame: Up to 10 years ]
  5. Change from baseline in Cognitive Development, as measured by changes in the raw scores, scaled scores and composite scores for the cognitive and language subscales of the Bayley Scales of Infant and Toddler Development (Bayley-III) at 10 years [ Time Frame: Up to 10 years ]
  6. Change from baseline in Cognitive Development, as measured by changes in raw and scaled subscale scores and composite scores and percentiles of Brief Scale IQ test of Leiter-R and/or Nonverbal IQ test of Leiter-3 (starting at 42 months of age) [ Time Frame: Up to 10 years ]
  7. Summary of Adverse Events [ Time Frame: Up to 10 years ]
