Clinical trials

This is a single-arm, open-label, non-randomized, single dose-escalation, first-in-human (FIH) clinical trial to evaluate the safety and preliminary efficacy of VG801 for treatment of patients with retinal dystrophy (Stargardt disease) due to biallelic ABCA4 mutations.

The goal of this phase 1 clinical trial is to learn about the safety and efficacy of a gene therapy, VG901, in patients with a rare disorder of the eye called Retinitis Pigmentosa. The main questions the study aims to answer are: * What is the best tolerated dose and are there any side effects, in particular any inflammatory reactions post drug administration? * Are there any early signs of efficacy on visual function? Participants will be administered a single intravitreal dose of VG901 into the most affected eye through a syringe and followed up for a year to monitor safety and efficacy. There will be two cohorts of participants in this study. Study Cohort 1 will receive the low dose and Study Cohort 2 will receive the high dose as specified in the Protocol.
