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

May 11, 2023 updated by: Frontera Therapeutics

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.

Study Overview

Detailed Description

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.
