  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 Pompe.

Further study details as provided by University of Florida:

Primary Outcome Measures:
  • Anti-rh GAA antibody titers [ Time Frame: 52 weeks ] [ Designated as safety issue: No ]
    Antibody titer for recombinant alpha acid glucosidase (GAA), or 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


Secondary Outcome Measures:
  • Safety Labs [ Time Frame: 52 weeks ] [ Designated as safety issue: Yes ]
    Reports from clinical labs including white count, Immune-globulin G (IgG), B-lymphocyte antigen (CD20) will be added to the study record when available every 4-12 weeks during the primary study and every 12 weeks for subjects who participate in the extension study (>52 weeks - 6 years)


Estimated Enrollment: 25
Study Start Date: October 2008
Estimated Study Completion Date: October 2018
Estimated Primary Completion Date: October 2018 (Final data collection date for primary outcome measure)
Groups/Cohorts
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
Study Population

The study population will consist of male and female patients age 0-65 years, with a diagnosis of early-onset Pompe Disease. Up to 25 subjects will be enrolled.

Criteria

Inclusion Criteria:

  • patients between the ages of 0 months and 65 years
  • 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, Gamunex, Hizentra, Zavesca 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
