Efficacy Study of GS010 for Treatment of Vision Loss From 7 Months to 1 Year From Onset in LHON Due to the ND4 Mutation (REVERSE)
United States, France, Germany37 participantsStarted 2016-01
Plain-language 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 more than six months and up to one year.

✓. Each eye of the participant maintaining visual ability to allow at least for counting of the examiner's fingers at any distance.
✓. Female participants (if of childbearing potential) must agree to use effective methods of birth control up to 6 months after IVT injection and male participants must agree to use condoms for up to 6 months after IVT injection.
✓. Ability to obtain adequate pupillary dilation to permit thorough ocular examination and testing.
✓. Signed written informed consent.
✓. Documented results of genotyping showing the presence of the G11778A mutation in the ND4 gene and the absence of the other primary LHON-associated mutations (ND1 or ND6) in the participant's mitochondrial DNA.

✕. Narrow angle in either eye contra-indicating pupillary dilation.
✕. Presence of disorders of the ocular media, such as the cornea and lens, which may interfere with visual acuity and other ocular assessments during the study period.
✕. Vision disorders, other than LHON, involving visual disability or with the potential to cause further vision loss during the trial period.
