| E.2 Objective of the trial | 
| E.2.1 | Main objective of the trial | 
| The study objectives are to assess: (1) the safety of the treatment; (2) the effects of treatment on the mean change in atrophic lesion area quantified from fundus autofluorescence images;
 (3) the effects of treatment on the mean change in low luminance best corrected visual acuity (BCVA);
 (4) the effects of  treatment on the mean change in standard BCVA;
 (5) the effects of treatment on the mean change in retinal sensitivity quatified using scotopic/mesopic microperimetry;
 (6) to characterize the systemic pharmacokinetic profile of Brimo DDS.

| E.3 | Principal inclusion criteria | 
| • Male or female patients 55 years of age or older as assessed at Screening Visit 1 The study eye must have:
 • Diagnosis of GA secondary to AMD, as assessed with fundus autofluorescence (FAF) at Screening Visit 1 and confirmed by the central reading center (CRC); these atrophic areas consist of funduscopically visible discrete areas characterized by a marked decrease in fundus autofluorescence intensity and loss of outer-retinal layers with choroidal signal enhancement as assessed with SD-OCT.
 Areas of atrophy must be multifocal lesions that contain all of the following characteristics:
 - At least one focal lesion must be equal to or larger than 0.2 mm2
 - The total lesion area must be greater than 1.25 mm2, but not larger than 18 mm2
 - The presence of banded or diffuse perilesional hyper-autofluorescence evident on fundus autofluorescence examination.
 - The distance between the optic disc or peripapillary atrophy and any atrophic lesion must be greater than 300 μm
 • Presence of drusen, yellow or white accumulations of extracellular material formed between Bruch's membrane and the retina pigmented epithelial cell layer, assessed with fundus photography and/or SD-OCT at Screening Visit 1 and confirmed by the CRC
 - BCVA better than or equal to 45 letters (20/125 Snellen equivalent) at Screening Visit 1 and the Baseline visit as assessed using the standard ETDRS (Early Treatment of Diabetic Retinopathy Study) visual acuity protocol
 - Clear ocular media and adequate pupil dilation to permit good quality retinal imaging as assessed at Screening Visit 1 and confirmed by the CRC
 - For patients participating in microperimetry assessments: abitity to complete repeat assessments of scotopic/mesopic microperimetry with an intra-visit, mean, retinal sensitivity reproducibility of 6 dB or less, as assessed at Screening Visit 2 and confirmed by the CRC
 •  The Fellow Eye must have Standard BCVA of 34 letters (Snellen equivalent 20/200) or better at Screening Visit 1
 
 |  | 
| E.4 | Principal exclusion criteria | 
| • History or evidence of choroidal neovascularization in either eye at Screening Visit 1, as confirmed by the CRC • Diagnosis of GA secondary to AMD that presents as unifocal atrophic lesions, lesions with no perilesional hyper-autofluorescence, lesions with only focal areas of perilesional hyper-autofluorescence on FAF examination of the study eye at Screening Visit 1 and confirmed by the CRC
 • Spherical equivalent of the refractive error of -6 diopters of myopia or worse (prior to cataract or refractive surgery) in the study eye at Screening Visit 1
