Inclusion Criteria: * Male or female, diagnosed with Pompe disease and between 18 and 65 years of age, inclusive * Participant has been on a stable regimen and dose of rhGAA for at least 3 months before screening (stable regimen defined as currently receiving rhGAA every 2 weeks and stable dose defined as not varying by more than ± 10%) * Participant has an estimated glomerular filtration rate (eGFR) ≥ 50 mL/min at Screening; eGFR to be estimated using the 4-parameter Modification of Diet in Renal Disease (MDRD) equation: eGFR (mL/min/1.73 m\^2) = 175 x (Scr)\^(-1.154) x (Age)\^(-0.203) x (0.742 if female) x (1.212 if African-American) * Male and female participants of childbearing potential agree to use medically accepted methods of contraception during the study and for 30 days after study completion * Participant is willing and able to provide written informed consent and is able to comply with all study procedures Exclusion Criteria: * Participant has had a documented transient ischemic attack, ischemic stroke, unstable angina, or myocardial infarction within the 3 months before Screening * Participant has clinically significant unstable cardiac disease (for example, cardiac disease requiring active management, such as symptomatic arrhythmia, unstable angina, or New York Heart Association class III or IV congestive heart failure) * Participant requiring mechanical ventilation or is confined to a wheelchair * Participant has a history of allergy or sensitivity to stud…

Questions worth asking your doctor

Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.

1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?

Generated to help you prepare — always confirm anything about your own eligibility and care with the study team and your doctor.

Questions for the trial coordinator

The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.

1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?

A starting point for the conversation — always confirm anything about your own eligibility, costs, and care with the study team and your doctor.
