Brief Summary:
This is a phase 1/2 open-label, ascending dose, multicenter clinical study to evaluate the safety and efficacy of AT845 in adult (aged ≥ 18 years) subjects, ambulatory or nonambulatory, with Late Onset Pompe Disease (LOPD).
Detailed Description:
This study (FORTIS) will evaluate the safety and efficacy of an investigational gene replacement therapy, AT845, in adult subjects with LOPD. Subjects will receive a single dose of AT845 delivered via intravenous (IV) infusion.
Up to 3 nominal dose levels of AT845 are planned to be evaluated in this study. A single AT845 administration via IV infusion is planned for each subject. The initial dosing cohort received a single dose of 3x10\^13 vg/kg of AT845. The second dose cohort will receive a single dose of 6×10\^13 vg/kg. The third dose cohort will receive a single dose of 1×10\^14 vg/kg. Dose escalation between cohorts will be based on evaluations of safety and in consultation with the independent DMC.
There will be a core observation period of 48 weeks with scheduled visits and assessments. Following the conclusion of the core observation period, subjects will be seen every 6 months for a safety follow-up visit for up to 5 years postdose.
