Study Summary

The objective of this clinical study is to evaluate the safety and efficacy of NR082 in the treatment of LHON caused by mitochondrial ND4 gene mutation. This study will enroll subjects aged ≥ 18 years old and ≤ 75 years old to receive a single unilateral intravitreal (IVT) injection of NR082 to evaluate its safety and efficacy. The clinical manifestations of all subjects are to be reduced visual acuity caused by LHON associated with ND4 mutation, with laboratory test showing G11778A mutation (a CLIA-certified laboratory) and reduced visual acuity lasted for \> 6 months and \< 10 years.
