Clinical Trial of Gene Therapy for Leber Congenital Amaurosis Caused by RPE65 Mutations

Leber Congenital Amaurosis Clinical Trial

Official title:
Phase I Trial of Ocular Subretinal Injection of a Recombinant Adeno-Associated Virus (rAAV2-hRPE65) Gene Vector to Patients With Retinal Disease Due to RPE65 Mutations

Clinical Trial Summary

The purpose of this clinical trial is to examine the safety of gene therapy for Lebers Congenital Amaurosis (LCA) caused by RPE65 mutations using a recombinant adeno-associated virus serotype 2 (rAAV2) vector carrying the human RPE65 (hRPE65) gene. Recently, three independent short-term gene therapy studies in humans with LCA due to RPE65 mutations were published, suggesting that subretinal delivery of rAAV virus carrying the RPE65 gene is safe. As a secondary outcome, improvement in visual function was observed in seven of the first nine treated patients. The proposed study is a similar open label, Phase I clinical trial of uniocular subretinal rAAV2-hRPE65 administration to individuals with RPE65-associated retinal disease. Two cohorts of three subjects each and one cohort of four subjects will be included in this trial. Cohort 1 and 2 will consist of individuals 18 years of age and older and Cohorts 3 will consist of individuals 8 years of age and older. In cohort 2, a larger volume of vector will be administered. Enrollment in Cohort 3 will begin only after confirming the safety of rAAV2-hRPE65 administration in the older group of participants.
