The goal of this observational study is to assess the safety and tolerability of AVR-RD-02 treatment in subjects who previously received AVR-RD-02 treatment (single dose administration).
Subjects who received AVR-RD-02 in the preceding treatment study (NCT04145037) and who meet all eligibility criteria may participate. Subjects will be asked to return for study visits annually for 14 years to assess measures of safety and persistence of AVR-RD-02 treatment.
