Safety Evaluation of Gene Therapy in Leber Hereditary Optic Neuropathy (LHON) Patients

Plain-language summary

This study evaluated the safety and tolerability profile of ascending doses of GS010 in patients with Leber Hereditary Optic Neuropathy (LHON). The Phase 1/2 trial enrolled participants aged 18 or older with a documented diagnosis confirmed by genetic testing showing the G11778A mutation in the mitochondrial ND4 gene, and visual acuity of 1/10 or worse in the less functional eye.

The summary above is a plain-language rendering of the official record. The original English title is shown for reference.
