Safety and Efficacy Study of rAAV2-ND4 Treatment of Leber Hereditary Optic Neuropathy (LHON)
Safety and Efficacy Study of a Single Intravitreal Injection of rAAV2-ND4 Treatment of Leber Hereditary Optic Neuropathy

This study is meant to assess the safety and efficacy of rAAV2-ND4 treatment of Leber hereditary optic neuropathy with 11778 LHON mutation.

Leber's Hereditary Optic Neuropathy (LHON) is a maternally inherited ocular disorder associated with a mutation in mtDNA . The common manifestation is visual loss which caused by the respiratory chain enzymes complex dysfunction resulting in increased oxidative stress enzymes production.

Material and Method Seven patients with 11778 LHON mutation were randomly treated with a Single IVT Injection of recombinant Adeno-Associated Virus-NADH dehydrogenase, subunit 4 (complex I)(rAAV2-ND4)(0.06ml/1.5×1010; The visual acuity, visual evoked potential (VEP),optical coherence tomography( OCT), computerized visual field, Electroretinography(ERG) and Liver and kidney function in plasma were compared before and after treatment at 1,3,and 6, months interval.
