New hope for kids with pompe disease: expanded access to experimental therapy

NCT ID NCT04327973

First seen Jun 26, 2026 · Last updated Jun 26, 2026 · Updated 1 time

Summary

This expanded access program offers a new treatment combination (ATB200 and AT2221) to children with infantile-onset Pompe disease who are not eligible for other clinical trials and are declining on standard enzyme replacement therapy. The goal is to provide access to this experimental therapy for up to 18 years old. While not a cure, it may help control the disease and improve outcomes.

What this could mean

Our plain-language read of the trial. This is informational only — not medical advice or a prediction.

Active substance
ATB200 (enzyme replacement therapy) co-administered with AT2221 (miglustat)
What this could lead to
If this treatment works, it could offer a new option for children with infantile-onset Pompe disease who are not doing well on standard therapy.
What could go wrong
This is an expanded access program, not a formal trial, so results are limited. The treatment may not work for everyone, and there are risks like infusion reactions or side effects from the drug combination.
