Pompe Disease Registry Protocol

The Pompe Registry is a global, multicenter, international, longitudinal, observational, and voluntary program for patients with Pompe disease, designed to track the disease's natural history and outcomes in patients, both treated and not. Data from the Registry are also used to fulfill various global regulatory commitments, to support product development/reimbursement, and for other research and non-research related purposes. The objectives of the Registry are: * To enhance understanding of the variability, progression, identification, and natural history of Pompe disease, with the ultimate goal of better guiding and assessing therapeutic intervention. * To assist the Pompe medical community with the development of recommendations for monitoring patients, and to provide reports on patient outcomes, to optimize patient care. * To characterize the Pompe disease population. * To evaluate the long-term effectiveness of alglucosidase alfa.

Clinical Study for Treatment-naïve IOPD Babies to Evaluate Efficacy and Safety of ERT With Avalglucosidase Alfa

This is a single group, treatment, Phase 3, open-label study to assess efficacy, safety, pharmacokinetic (PK), pharmacodynamics (PD) of avalglucosidase alfa in treatment-naïve male and female participants with IOPD. Study details include: * Study duration: Screening - up to 4 weeks; * Primary Analysis Period (PAP) - 52 weeks; * Extended Treatment Period (ETP) - 52 weeks; * Extended Long term Treatment Period (ELTP) - 104 weeks; 4-week follow-up period for a total study duration - up to 4.08 years. * Treatment duration: Up to 4 years * Visit frequency: every other week and potentially every week

China Post-approval Commitment (PAC) Study of Avalglucosidase Alfa in Participants With IOPD

This is a single group, 52-week treatment, Phase 4, open-label, single-arm study to assess the safety and efficacy of avalglucosidase alfa IV infusion in male and female Chinese participants with IOPD who are treatment-naïve or were previously treated with ERT. Study details include: * The study duration: total study duration is approximately 64 weeks. * Screening period of up to 8 weeks * Treatment period of 52 weeks * Follow-up period of 4 weeks. (if the participant enrolls in another study or receives commercially available ERT, the follow-up period may be reduced from 4 to 2 weeks) * The number of visits will be 30, including 29 site visits and 1 phone call follow-up visit.

Avalglucosidase Alfa French Post-trial Access for Participants With Pompe Disease (PTA Avalglucosidase)

This long-term open label safety and efficacy study is intended to follow up, and to provide post-trial access to enzyme replacement therapy (ERT) with avalglucosidase alfa to patients with Pompe disease in France who have completed Study EFC14028, LTS13769, or ACT14132, from market authorization until reimbursement of avalglucosidase alfa in France or until September 2026, whichever comes first. \- Study visit frequency: every 2 weeks

A Prospective Study to Observe & Describe Clinical Outcomes of Alglucosidase Alfa Treatment in Patients ≤6 Months of Age With Infantile-onset Pompe Disease (IOPD)

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.

A Gene Transfer Study for Late-Onset Pompe Disease (RESOLUTE)

The purpose of this study is to evaluate the safety, tolerability, and efficacy of a single intravenous infusion of SPK-3006 in adults with clinically moderate, late-onset Pompe disease receiving enzyme replacement therapy (ERT). Participants will be treated in sequential, dose-level cohorts.

Treatment Frequency Reduction in Pompe Disease

The aim of this study is to assess if dosing frequency reduction of alglucosidase alfa 20 mg/kg once every 2 weeks to once every 4 weeks is safe and does not lead to increased progression of disease in a selected group of patients with late-onset Pompe disease.

Higher Dose of Alglucosidase Alpha for Pompe Disease

This study is aimed to investigate that whether the higher dose ERT improve safety and clinical outcomes of Pompe disease patients. Also, wish to develop a new therapeutic recommendation and hope that it could improve the long-term outcomes of Pompe diesease patients.
