Inclusion criteria
. Male or female subjects (ERT-naïve \[have never received a dose of rhGAA\] or ERT-experienced \[have received rhGAA every 2 weeks for at least 6 months immediately before enrollment, and if ERT dosage has been modified, must have been on the modified dosage for at least 3 months before enrollment\]) diagnosed with LOPD who are aged 12 to \<18 years at screening (Cohort 1 only) or aged 0 months to \< 12 years at screening (Cohort 2 only)
. Subject weighs ≤ 115 kg. (Cohort 1 Only)
. Subject must have a diagnosis of LOPD based on documentation as defined in study protocol
. If of reproductive potential and if sexually active, female and male subjects agree to use a highly effective method of contraception throughout the duration of the study and for up to 90 days after their last dose of Cipaglucosidase Alfa/Miglustat
. Subject has a sitting forced vital capacity (FVC) ≥ 30% of the predicted value for healthy Adolescents at screening (Cohort 1 only)
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.
What they're measuring
1
Incidence of treatment-emergent adverse events (TEAEs) from baseline
. Subject (aged 12 to \<18 years; Cohort 1) performs one 6-Minute Walk Test (6MWT) (≥ 75 meters) at screening that is valid, as determined by the clinical evaluator, or subject (aged ≥ 5 to \< 12 years; Cohort 2) performs one 6MWT (≥ 40 meters) at screening that is valid, as determined by the clinical evaluator
Exclusion criteria
. Subject has received any investigational/experimental drug, oral anabolic steroid or derivative, biologic, or device within 30 days or 5 half-lives of the therapy or treatment, whichever is longer, before screening
. Subject has received treatment with prohibited medications within 30 days of screening
. Subject has received any gene therapy at any time
. Subject has any intercurrent illness or condition at screening or baseline that may preclude the subject from fulfilling the protocol requirements or suggests to the investigator and/or the medical monitor that the potential subject may have an unacceptable risk by participating in this study
. Subject has a hypersensitivity to any of the excipients in ATB200, approved rhGAA, or AT2221
. Female subject is pregnant or breast-feeding at screening
. Subject requires the use of ventilation support for \> 6 hours per day while awake
. Subject has evidence of moderate to severe hypertrophic cardiomyopathy aligning with classic IOPD
