Gene therapy for inherited blindness passes early safety check
NCT ID NCT02064569
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tested a gene therapy called GS010 in 19 adults with Leber Hereditary Optic Neuropathy (LHON), a rare inherited eye disease that causes rapid vision loss. The main goal was to see if the treatment is safe and tolerable at different doses. The therapy uses a harmless virus to deliver a working gene to the eye, aiming to stop or slow vision loss.

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.
Inclusion Criteria: Documented diagnosis of LHON based on a genetic test confirming the presence of the G11778A mutation in the mitochondrial ND4 Age 18 years old or older at the time of study entry (informed consent signature) Visual acuity ≤ 1/10 of the less functional eye Exclusion Criteria: Any known allergy or hypersensibility to one of the product used during the trial Contraindication to IVT surgery (anaemia Hb \<8g/dl, severe cardiovascular disease, severe coagulopathy…) Disorder of the ocular humors and of the internal retina involving visual disability Glaucoma Presence of other pathology whose symptoms or associated treatments might affect the retina or the optic nerve Vascular retinal occlusion Narrow angle contra-indicating pupillary dilation Other cause of optic neuropathy (inflammatory conditions or exposure to toxins...) Patients presenting known mutation of other genes implicated in pathological retinal conditions
