Study Endpoints
Primary Endpoints
Change in functional vision from baseline to week 52 in pooled analysis when study eyes in treatment group were compared to study eyes in untreated control
52 weeks

Change in functional vision from baseline to week 52 in pooled analysis from retinitis pigmentosa subjects when study eyes in treatment group were compared to study eyes in untreated control, as measured by the ability of a study participant to navigate through a maze in Luminance Dependent Navigation Assessment (LDNA)

Secondary Endpoints
Change in functional vision from baseline to week 52 in all the treated eyes from RP subjects (study eyes + fellow treated eyes) when compared to all the eyes (study eyes and fellow eyes) in untreated control group
52 weeks
Change from Baseline in visual function in patients with retinitis pigmentosa when treatment group were compared to untreated controls
52 weeks
Change from baseline in LDNA Lux-level results in treated subjects when compared to the untreated controls
