AB-1009 Gene Therapy for Late-Onset Pompe Disease

This study is testing a new gene therapy called AB-1009 for adults with late-onset Pompe disease (LOPD). AB-1009 is given as a single infusion into a vein. The main goal is to see how safe AB-1009 is and if it causes any side effects. Researchers will also look at how well it works. You might be able to join if you are between 18 and 65 years old, have a confirmed diagnosis of LOPD, and have already received enzyme replacement therapy. The study plans to enroll up to 12 participants.

Study design
This is an open-label study, meaning both you and the study team will know which treatment you are receiving. It will include up to 12 participants and test two different doses of AB-1009.
What's involved
You would have a screening period of up to 75 days, followed by a primary observation period of 52 weeks after receiving the infusion.
Compensation
Not stated in the trial record.
Follow-up
After the primary observation period, participants will be followed for an additional 4 years to monitor their health.
