Summary

This trial will test a new treatment for Leber's Hereditary Optic Neuropathy (LHON) caused by a genetic mutation. Participants aged 18-75 will get a single injection in the eye to evaluate the safety, tolerability, and efficacy.

Who is the study for?
This trial is for adults aged 18 to 75 with vision loss from Leber's Hereditary Optic Neuropathy (LHON) due to ND1 gene mutation, present for more than 6 months but less than 10 years. Participants must have a specific genetic mutation (G3460A), and their worst eye's visual acuity should be at least Hand Motion VA. Men must use contraception post-treatment.
What is being tested?
The NFS-02 Injection is being tested in this study. It involves a one-time injection into the eye of individuals with LHON to check its safety, how well it's tolerated, and initial effectiveness in improving vision or slowing down vision loss.
What are the potential side effects?
While not explicitly listed here, potential side effects may include discomfort or complications related to intravitreal injections such as eye inflammation, infection risk increase around the injection site, bleeding inside the eye, retinal detachment or cataracts.
