Pompe disease long-term monitoring with avalglucosidase alfa
Official title: Long Term Follow-up for Patients With Pompe Disease Undergoing Compassionate Use and Transitioning to Medication Listed Under the National Health Insurance.
Run by National Taiwan University Hospital · NCT07834320 · Data updated 2026-11-12
This is an observational program to see how people with Pompe disease who started avalglucosidase alfa fare over time, including biomarkers, muscle and breathing function, and safety.

Is this trial a fit for you?
✓Likely a good fit
Pompe disease patients who have switched to avalglucosidase alfa and have confirmed GAA deficiency or two pathogenic GAA gene variants.
✕Probably not a fit
Patients who do not show changes in the measured endpoints or who discontinue treatment early may not observe benefits in this program.

What this trial studies
This observational program collects clinical data from Pompe patients who switch to avalglucosidase alfa, tracking adverse events and several effectiveness measures. Primary focus is urinary Glc4/Hex4 as an indicator of treatment effect, with additional data on creatine kinase, motor function via the Quick Motor Function Test, and forced vital capacity for respiratory function. The evolution of these measures will be described and compared to each patient’s baseline before initiation or prior to a year before initiation, enabling descriptive analyses at the individual level. The study is conducted at National Taiwan University Hospital, led by NTUH with no listed collaborators.
Why it matters
Potential benefit: Participants may gain a better understanding of how avalglucosidase alfa affects biomarkers, motor and respiratory function, and safety over time.
How similar studies have gone: Prior studies of avalglucosidase alfa in Pompe disease have reported variable biomarker and functional changes; this program adds real-world long-term observations.
