Study Summary

A recombinant adeno-associated virus serotype 2 (rAAV2) vector has been altered to carry the human RPE65 (hRPE65) gene. This vector has been shown to restore vision in animal models that resemble human RPE65-associated Leber congenital amaurosis (LCA), an incurable retinal degeneration that causes severe vision loss. The proposed study is an open label, Phase I clinical trial of subretinal rAAV2-CBSB-hRPE65 administration to individuals with RPE65-associated retinal disease. Five cohorts will be included in this trial. Cohorts 1, 2 and 4 will consist of individuals 18 years of age and older. Cohorts 3 and 5 will consist of individuals between the ages of 8 and 17, inclusive. Enrollment in Cohorts 3 and 5 will begin only after confirming the safety of rAAV2-CBSB-hRPE65 administration in the older groups of participants. This trial will lead to a greater understanding of the safety and thereby potential value of gene transfer in RPE65-associated retinal disease and will have implications for other forms of retinal degenerative disease amenable to this type of intervention. The goal of this clinical trial is to determine the safety of uniocular subretinal administration of rAAV2-CBSB-hRPE65 in individuals with RPE65-associated retinal disease. Ocular and systemic toxicity will be assessed prior to and following vector administration to determine if there are adverse changes that may be associated with vector administration.
