What are the main findings? Response: This study examines the efficacy (and safety) of treating children and adults with a form of retinitis pigmentosa known as RPE65-associated Lebers congenital amaurosis, with an adeno-associated viral vector(AAV) delivered RPE65 construct.  Building on successful phase 1/2b trials from multiple centers, the AAV-hRPE65v2 agent now designated as voretigene neparvovec, contains a highly optimized enhancing sequence and promoter. The main findings were an improvement on a multiple light level mobility test (MLMT) and multiple additional supportive secondary endpoints which included improvements in full-field light sensitivity, Goldmann visual field, and others.
