Purpose
The purpose of this research study is to determine the effect(s) of medications that alter the immune system on anti-rhGAA immune response in Pompe patients receiving rhGAA enzyme replacement therapy (ERT), and to understand the immune response in Pompe patients treated with ERT that do not make antibodies against ERT. The investigators would also like to determine whether treating Pompe Disease with medications that affect the immune system has any effects on the overall health or disease progression of children with Pompe.

| Official Title: | Effects of Immunomodulation Therapy on Anti-rhGAA Immune Response in Children With Pompe Disease Receiving rhGAA Replacement Therapy |
- Anti-rh GAA antibody titers [ Time Frame: 52 weeks ] [ Designated as safety issue: No ]anti-rh-GAA antibody titers will be evaluated at baseline and every 4-8 weeks for 52 weeks of participation in the primary study. Subjects who continue participation in the extension study (>52 weeks - 3 years, anti-rh-GAA antibody titers will be evaluated every 12 weeks
- Safety Labs [ Time Frame: 52 weeks ] [ Designated as safety issue: Yes ]Safety labs including white count, IgG, CD20 will be evaluated every 4-12 weeks during the primary study and every 12 weeks for subjects who participate in the extension study (>52 weeks - 6 years)
Biospecimen Retention: Samples With DNA
Primary Skin cell fibroblast line will be maintained and any residual blood samples will be stored as serum and plasma when available.

Age 0 months to 65 years
With a diagnosis of early-onset Pompe Disease. Total of 25 subjects enrolled, some of who will be candidates for immunomodulation therapy.
|
Eligibility| Ages Eligible for Study: | up to 65 Years |
| Genders Eligible for Study: | Both |
| Accepts Healthy Volunteers: | No |
| Sampling Method: | Non-Probability Sample |
The study population will consist of male an female patients age 0-65 years, with a diagnosis of early-onset Pompe Disease. Up to 25 subjects will be enrolled.
Inclusion Criteria:
- diagnosed with early-onset Pompe Disease, confirmed by mutational analysis and/or GAA enzyme assay
- eligible regardless of whether they have begun enzyme replacement therapy prior to enrollment
- all subjects will receive ERT as standard of care during the course of the study, although they may not have begun ERT treatment at the time of enrollment
- subjects may receive an immunomodulatory regimen as part of their standard of care; this may include rituximab, sirolimus, methotrexate, IVIG or other immunomodulatory agents, alone or in combination, at the discretion of their caregiver(s)
Exclusion Criteria:
- subject is unable to meet the study requirements
- subjects medical condition contraindicates participation or Study Investigators feel that participation is otherwise not in the Subject's best interest
- subject does not receive ERT treatment
