Gene Therapy in Subjects With Biallelic RPE65 Mutation-associated Retinal Dystrophy

A Multi-center, Open-label, Dose-escalation Phase I/II Clinical Study to Evaluate the Safety, Tolerability and Efficacy of FT-001 Administered Via Subretinal Injection in Subjects With Biallelic RPE65 Mutation-associated Retinal Dystrophy

The goal of this clinical trial is to evaluate the safety, tolerability and efficacy of subretinal administration of FT-001 in subjects with biallelic RPE65 mutation-associated retinal dystrophy.

This study is a multi-center, open-label, phase I/II clinical study to evaluate the safety, tolerability, efficacy, immunogenicity, and in vivo biodistribution characteristics of FT-001 in subjects with biallelic RPE65 mutation-associated retinal dystrophy. Assessments will include visual acuity, vector shedding, immunogenicity and adverse events. Participants will be monitored for 5 years after treatment.

Exclusion Criteria:

1. Other interfering eye diseases
2. Presence of any systemic or ocular disease that can cause or likely to cause vision loss
3. There is evidence of obviously uncontrolled concomitant diseases
4. Known to have active or suspected autoimmune diseases
5. With active systemic infection under treatment
6. Pregnant or lactating women
