Change From Baseline in Cardiac Function at Week 52 [ Time Frame: Baseline, Week 52 ]
Cardiac function was measured by the left ventricular mass Z-score (LVM-Z). Z-Scores indicate the number of standard deviations (SD) from the mean in a normal distribution. A negative change from baseline indicates a decrease and positive change from baseline indicates an increase in LVM Z-score. The normal range is -2 to 2 and greater than 2 may indicate left ventricular hypertrophy.
Change from baseline in cardiac function as measured by the left ventricular mass index Z-score(LVMI-Z) [ Time Frame: 52 weeks ]

  • Percentage of Participants With Estimated Probability of Survival [ Time Frame: Up to Week 52 ]
  • Number of Participants With Invasive Ventilator-Free Survival [ Time Frame: Up to Week 52 ]
    Invasive ventilator-free survival was defined as the time during which the participant is alive and not invasively ventilated. Number of Participants with invasive ventilator-free survival were reported.
  • Change From Baseline in Motor Development Status at Week 52 [ Time Frame: Baseline, Week 52 ]
    Motor development status was assessed by the Gross Motor Function Measure - 88 Scale (GMFM-88) total percent scores. GMFM-88 is an 88-item measure to detect gross motor function. It consists of 5 categories: lying and rolling; sitting; crawling and kneeling; standing; walking, running and jumping. Each item was scored on a 4-point Likert scale (0 = cannot do; 1 = initiates [<10% of the task]; 2 = partially completes [10% to <100% of the task]; 3 = task completion). The score for each dimension was expressed as a percentage of the maximum score for that dimension. Total score ranges from 0% to 100%, where higher scores indicate better motor functions.

A Noninferiority Study of Alglucosidase Alfa Manufactured at the 160 L and 4000 L Scales in Treatment Naïve Patients With Infantile-Onset Pompe Disease
A Phase 3/4, Prospective, Multinational, Open-label, Noninferiority Study of Alglucosidase Alfa Manufactured at the 160 L and 4000 L Scales in Treatment Naïve Patients With Infantile-Onset Pompe Disease
A study to demonstrate comparable safety, efficacy, and pharmacokinetics (PK) of alglucosidase alfa manufactured at the 160 litre (L) and 4000 L scales in participants who had been diagnosed with infantile-onset Pompe disease. Participants were treated with alglucosidase alfa 160 L scale product in the United States (US) and 4000 L scale product in the regions outside the US.
