A Prospective Study to Observe & Describe Clinical Outcomes of Alglucosidase Alfa Treatment in Patients ≤6 Months of Age With Infantile-onset Pompe Disease (IOPD)
United States, Belgium, France16 participantsStarted 2021-06-10
Plain-language summary
Primary Objective:
To describe the effect of routine practice with alglucosidase alfa in patients with IOPD ≤6 months of age, on invasive ventilation-free survival after 52 weeks of treatment.
Secondary Objectives:
* To describe the effect of routine practice with alglucosidase alfa on invasive ventilation-free survival and survival at 12 and 18 months of age, as well as on change in left ventricular mass (LVM) Z score, Alberta Infant Motor Scale (AIMS) score, body weight, body length, and head circumference Z scores, and urinary glucose tetrasaccharide (Hex4), at Week 52 of treatment.
* To describe the safety, tolerability, and immunogenicity of alglucosidase alfa in the routine practice of IOPD treatment.

Inclusion Criteria:
* At the time of informed consent, participants must be ≤6 months of age, corrected for gestation if necessary. Gestational age \<40 weeks will be adjusted to a full-term gestational age of 40 weeks.
* Participants must have alglucosidase alfa enzyme replacement therapy (ERT) planned or initiated for IOPD treatment irrespective of study participation, according to the treating physician's decision regarding participants' routine disease management.
* Participants must have available and accessible medical records from the time of IOPD diagnosis and from subsequent follow-up.
* Participants must have a confirmed diagnosis of IOPD, defined as presence of 2 pathogenic acid alpha glucosidase (GAA) variants and documented GAA deficiency in blood (dried blood spot \[DBS\] accepted), skin, or muscle tissue, or presence of 1 pathogenic GAA variant and documented GAA deficiency in blood, skin, or muscle tissue from separate samples (either from 2 different tissues or from the same tissue but at 2 different sampling dates.) (DBS and leukocytes are acceptable as 2 different samples from blood).
* Participants must have established cross-reacting immunologic material (CRIM) status available prior to enrollment. CRIM status may be provided by historical CRIM testing results or prediction of CRIM status based on genotyping performed at a Clinical Laboratory Improvement Amendments (CLIA) or other appropriately certified genetic laboratory.
* Participants must have cardi…
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.
