Outcome

Type	Measure	Description	Time frame	Safety issue
Other	Evaluation of therapy safety	Evaluation of major ocular adverse events (bacterial or fungal septic endophthalmitis, retinal detachment, vitreous proliferative-fibrotic reaction with retinal traction, secondary glaucoma, phthisis bulbs, iris rubeosis), studied at slit-lamp evaluation in the anterior and posterior chambers.	1 year
Primary	Autofluorescence atrophy area changes in treated eyes compared with sham group	Stabilization of enlargement of hypoautofluorescent area (atrophy) or at most a maximum increase of no more than 20% compared with baseline in treated subjects compared with placebo group from baseline until follow-ups	1 year
Primary	Autofluorescence atrophy area changes in treated eyes compared with sham group (1)	Stabilization of the enlargement of the hyperfluorescent area (atrophy enhancement) or at most a maximum increase of not more than 20% from the baseline	1 year
Secondary	ETDRS visual acuity	Increase of at least two lines from baseline measurement and/or to the contralateral untreated eye at 3 and 6, 12, months.	1 year
Secondary	Mean increase in ONL thickness and retinal volumetrics	Mean increase, measured by high-resolution quantitative OCT, of at least 20% from baseline at 3 and 6, 12, months	1 year
Secondary	Mean increase in retinal volumetrics	Mean increase, measured by high-resolution quantitative OCT, of at least 20% from baseline at 3 and 6, 12, months	1 year
Secondary	Stabilization of the atrophy region of the EPR	Stabilization in enface OCT with less than 20% increase from baseline, comparing it with the placebo group, at 3 and 6, 12, months.	1 year
Secondary	Retinography of the ocular fundus	Change in ocular fundus	1 year
Secondary	Incomplete retinal pigment epithelial (RPE) and outer retinal atrophy (iRORA)	Change during follow ups	1 year
Secondary	Outer retinal atrophy (iRORA)	Change during follow ups	1 year
