First seen Jun 27, 2026 · Last updated Jun 27, 2026

Summary

This study follows 17 people with Pompe disease who have already taken part in earlier trials of avalglucosidase alfa (Nexviadyme). It aims to check the drug's long-term safety and effectiveness by giving it every two weeks as an IV infusion. The study will continue until the drug is covered by French health insurance or until September 2026.

What this could mean

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

Active substance

Avalglucosidase alfa (Nexviadyme), an enzyme replacement therapy given by IV infusion every 2 weeks

What this could lead to

If successful, this study could confirm that long-term use of avalglucosidase alfa is safe and helps manage Pompe disease symptoms.

What could go wrong

This is a small, open-label extension study with only 17 participants, so results may not apply to everyone. Side effects like infusion reactions are possible.
