A Randomized, Double-Masked, Sham-Controlled Clinical Trial to Evaluate the Efficacy of a Single Intravitreal Injection of GS010 in Subjects Affected for 6 Months or Less by LHON Due to the G11778A Mutation in the Mitochondrial ND4 Gene
In Brief
A Phase 3 clinical trial evaluating GS010 and Sham Intravitreal Injection for Optic, Atrophy, Hereditary, Leber. Completed, enrolled 39 participants across 7 sites in 5 countries.
Detailed Summary
The goal of this clinical trial is to assess the effectiveness of GS010, a gene therapy, in improving the visual outcome in participants with Leber Hereditary Optic Neuropathy (LHON) due to the G11778A ND4 mitochondrial mutation when vision loss is present for six months or less.

Timeline
Interventions
Both eyes of each participant will receive standard antiseptic preparation, administration of topical local ocular anesthetic agents and will undergo pupillary dilation. Administration of an intra-ocular pressure lowering agent will precede treatment for every participant. GS010-treated Eyes: GS010 is a recombinant adeno-associated viral vector serotype 2 (rAAV2/2) containing the wild-type ND4 gene (rAAV2/2-ND4). Participants will receive a single dose of GS010 in one of their randomly selected eyes, via intravitreal injection containing 9E10 viral genomes in 90μL balanced salt solution (BSS) plus 0.001% Pluronic F68®.
Both eyes of each participant will receive standard antiseptic preparation, administration of topical local ocular anesthetic agents and will undergo pupillary dilation. Administration of an intra-ocular pressure lowering agent will precede treatment for every participant. Sham-treated Eyes: One eye of each participant will undergo sham injection. Sham intravitreal injection will be performed by applying pressure to the eye at the location of a typical intravitreal injection procedure using the blunt end of a syringe without a needle.
