About this trial
Evaluate short- and long-term biomarker, motor function, respiratory function and safety with avalglucosidase alfa in IOPD and LOPD patients who switched from other ERT.

Trial outcomes
Primary outcomes
Urinary Glc4/Hex4
the primary endpoints for effectiveness analysis of avalglucosidase alfa. Urinary Glc4/Hex4 is usually elevated in Pompe patients and are sensitive though nonspecific biomarkers for diagnosis and monitoring of IOPD or LOPD
Secondary outcomes
Creatine kinase
Serum CK is usually elevated in Pompe patients and are sensitive though nonspecific biomarkers for diagnosis and monitoring of IOPD or LOPD (Kishnani et al., 2006; Li et al., 2021; Young et al., 2009).
motor function (Quick Motor Function Test)
QMFT score is strongly correlated with proximal muscle strength, and significantly differentiated between patients with different levels of mobility (van Capelle et al., 2012), muscle function will be assessed by QMFT annually.
respiratory function (forced vital capacity).
Pulmonary function will be assessed by forced vital capacity. For infants, pulmonary function tests are difficult to administer and therefore data might be limited.
