Long-term follow-up of individuals with Pompe disease

Determination of Cross-Reactive Immunological Material (CRIM) Status and Longitudinal Follow-up of Individuals With Pompe Disease

Observational Duke University · NCT01665326

What this trial studies

This observational study focuses on the natural history of infantile Pompe disease, a genetic disorder caused by a deficiency in the enzyme acid alpha-glucosidase. Researchers will collect and analyze medical data over time, including responses to enzyme replacement therapy (ERT) with alglucosidase alfa and the impact of immunosuppressive therapy in patients who develop antibodies against ERT. The study aims to understand the relationship between Cross-Reactive Immunological Material (CRIM) status and treatment outcomes, providing insights into patient tolerance to ERT and potential complications. Regular assessments will include clinical parameters, laboratory values, and antibody testing results.

Who should consider this trial

Good fit: Ideal candidates for this study are individuals diagnosed with infantile, atypical, or juvenile onset Pompe disease.

Not a fit: Patients who do not have a confirmed diagnosis of Pompe disease or those who cannot provide informed consent may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could improve treatment strategies for patients with Pompe disease by identifying factors that influence their response to enzyme replacement therapy.

How similar studies have performed: Other studies have shown success in understanding the natural history and treatment responses in Pompe disease, making this approach both relevant and valuable.
