Evaluate the Safety and Preliminary Efficacy of EXG110 in Subjects With Fabry Disease 12

Recruiting
Clinical Trial NCT06539624 is an interventional study for Fabry Disease that is recruiting. It started on 16 October 2024 with plans to enroll 12 participants. Led by The Children's Hospital of Zhejiang University School of Medicine, it is expected to complete by 9 April 2027. The latest data from ClinicalTrials.gov was last updated on 27 February 2026.
Brief Summary
Objective: To explore the safety and tolerability of different doses of EXG110 with Fabre disease
Detailed Description
An open-label, multicenter, single-arm, non-randomized, dose-escalation, and recommended dose-extension clinical design was used to evaluate the safety and efficacy of a single intravenous administration of different doses of EXG110 in patients

ExperimentalDose escalation-Cohort 1
Genetic : EXG110
EXG110 injection
EXG110 is a recombinant adeno-associated virus (rAAV) that not only significantly increases plasma AGA activity, but is also highly expressed in target organs such as the heart and kidneys.EXG110 will be administered in a single dose by intravenous infusion.
ExperimentalDose escalation-Cohort 2
Genetic : EXG110
EXG110 injection
EXG110 is a recombinant adeno-associated virus (rAAV) that not only significantly increases plasma AGA activity, but is also highly expressed in target organs such as the heart and kidneys.EXG110 will be administered in a single dose by intravenous infusion.
ExperimentalDose escalation-Cohort 3
Genetic : EXG110
EXG110 injection
EXG110 is a recombinant adeno-associated virus (rAAV) that not only significantly increases plasma AGA activity, but is also highly expressed in target organs such as the heart and kidneys.EXG110 will be administered in a single dose by intravenous infusion.
ExperimentalDose escalation-Cohort 4
Genetic : EXG110
EXG110 injection
EXG110 is a recombinant adeno-associated virus (rAAV) that not only significantly increases plasma AGA activity, but is also highly expressed in target organs such as the heart and kidneys.EXG110 will be administered in a single dose by intravenous infusion.
