Safety Study of an Adeno-associated Virus Vector for Gene Therapy of Leber's Hereditary Optic Neuropathy
Completed · Phase 1
Conditions studied: Leber's Hereditary Optic Neuropathy
In brief
The study is a dose-escalation study, phase 1. The objective of this proposed clinical trial is to evaluate the safety of mitochondrially targeted ND4 gene therapy with the adeno-associated viral vector in appropriate LHON patients.

- Pregnant or nursing women or unwillingness for subject with childbearing potential to use contraception during the first year of the study.
- Optic disc drusen on exam or in previous history.
- Ocular diseases or visual dysfunction conditions other than refractive error (e.g. amblyopia, glaucoma, etc.) in the eye selected for the injection.
- Previous eye surgery in the eye selected for injection.
- Aspartate transaminase (AST)/alanine transaminase (ALT) >5.0 x upper limit of normal (ULN); Total bilirubin >3 x ULN; Hemoglobin < 8 g/dL; neutrophil count <1.0 x 109/L; or platelet count < 50 x 109/L
- a) Any laboratory screening test that meets the abnormality criteria stated above can be repeated once between Baseline one to Baseline 2.

- History of neurodegenerative conditions (e.g. multiple sclerosis, neuromyelitis optica, Parkinson's disease)
- History of autoimmune conditions (e.g. systemic lupus erythematosus)
- Systemic diseases having ocular manifestations likely to confound assessment of study results. History of cancer within five years other than localized basal or squamous cell carcinoma not near the orbital area. Patients with a prior history of cancer will need documentation from their cancer specialist that the cancer was cured at least 5 years before study entry.
