Protocol Summary 
Study Compound:  AGN-190342, Brimonidine Posterior Segment Drug Delivery System (Brimo DDS®) 
Phase:  2b 
Study Objectives:  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 (FAF) 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 quantified using 
scotopic/mesopic microperimetry; and (6) to characterize the systemic pharmacokinetic profile of Brimo DDS  
Clinical Hypotheses: 
• 
Brimo DDS is safe and well tolerated with repeated intravitreal administration in patients with 
geographic atrophy (GA) secondary to age-related macular degeneration (AMD) as assessed by the 
incidence of adverse events 
• 
Brimo DDS is more effective than Sham treatment in slowing the growth of atrophic lesion area and 
the loss of standard and low luminance BCVA 
 
Study Design 
Structure:  Multicenter, randomized, double-masked, Sham treatment-controlled study  
Duration:  30 months 
Study Treatment Group:  400 µg Brimo DDS administered by intravitreal injection 
Control:  Sham treatment with needleless DDS applicator 
Dosage/Dose Regimen:  One treatment to the study eye every 3 months from Baseline (Day 1) through 
Month 21 
Randomization/Stratification:  Randomization to treatment groups will use a 1:1 allocation ratio and will be 
stratified by region (North America, Europe, and Australia) and by atrophic lesion area (≤ 8 mm2 versus 
> 8 mm2) in the study eye as assessed by FAF examination at Screening Visit 1 and quantified by the central 
reading center (CRC).

General Statistical Methods and Types of Analyses:   
Analysis of safety data will be based on the safety population, ie, all patients who received at least one study 
treatment.  Analysis of efficacy data will be based on the modified intent-to-treat population (mITT), ie, all 
randomized and treated patients with baseline and at least one post-baseline data point for atrophic lesion area.  
All analyses will be based on the actual treatment that the patient received. 
The primary analysis for efficacy will be performed when all enrolled patients have completed the Month-24 
visit or have exited early, prior to Month 24.  An interim analysis may be performed after 50% of patients 
complete the Month-18 visit.  Three database locks are planned for the study:  an interim lock at Month 18 
(50% of patients), the primary lock at Month 24, and the final lock at the end of the study (Month 30). 
The primary efficacy variable is the change from Baseline in atrophic lesion area in the study eye as assessed 
with FAF and quantified by the CRC.  Statistical analysis will be based on a mixed model for repeated measures 
(MMRM). The model includes treatment, study region (North America, Europe, and Australia), analysis visit, 
and treatment-by-visit interaction as factors as well as the baseline value and baseline value-by-analysis visit 
interaction as covariates.  
The Medical Dictionary for Regulatory Activities (MedDRA) nomenclature will be used to code adverse 
events.  The number and percent of patients reporting adverse events will be tabulated by primary system organ 
class, preferred term, and severity using the safety population. 
Sample Size Calculation: 
A standard method for measuring disease progression in patients with GA secondary to AMD is to quantify the 
expansion rate of the areas of atrophy.  Over a 12-month period this expansion rate typically ranges between 1 
and 2 mm2 (Sunness et al, 2007; Holz et al, 2007; Holz et al, 2010).  The atrophic lesion expansion rate used in 
the sample size calculation for the current study was from the GAP study (Holz et al, 2010).  The selection of 
the GAP data was based on the large patient population in this natural history study and because of the 
similarities between the GAP study and the current study in both study design and patient populations.   
The 12-month lesion expansion rate from the GAP study was 1.73 mm2.  A projected 24-month expansion rate, 
2.8 mm2, was calculated by applying a 20% discount to a linear extrapolation of the GAP lesion expansion data. 
Based on this lesion expansion rate and assuming a common standard deviation of 1.65 mm2, a 2-sided t-test 
with 90% power and an alpha of 0.05 will require a sample size of 120 patients per group to detect a 25% 
reduction from the Sham treatment.  A 25% reduction from the Sham treatment corresponds to a treatment

difference of 0.70 mm2.  With an anticipated dropout rate of 20%, approximately 300 patients will be enrolled 
such that 240 (120 per group) will complete the Month 24 visit.

Background and Clinical Rationale 
Age-related macular degeneration (AMD) is the leading cause of legal blindness in persons 
over the age of 65 years (Friedman et al, 2004; Klein et al, 2006; Chakravarthy et al, 2007).  
Vision loss with this disease is attributed in large part to the advanced stages of this disease, 
exudative AMD and geographic atrophy (GA).  While antibody fragments and antibody 
mimetics directed against vascular endothelial growth factor (VEGF) are effective treatments 
for exudative AMD (Rosenfeld et al, 2006; Brown et al, 2006; Heier et al, 2012), GA remains 
a large unmet medical need because of its high incidence and the absence of effective 
treatments.  Klein and colleagues (2006) have reported that the 15 year cumulative incidence 
of GA in individuals 43 to 86 years old with early signs of AMD was 14%.  In individuals 
over 85 years of age the incidence of GA is approximately 4 times that of exudative AMD 
(Klein et al, 2007). 
GA is characterized by the degeneration of the retinal pigment epithelium (RPE), 
photoreceptor cells and choriocapillaris (Nowak, 2006).  These morphological changes 
initially appear in the extrafoveal region and advance into the fovea as the disease progresses.  
In earlier stages when the disease is limited to the extrafoveal region, the atrophic lesions 
impair visual performance by limiting the size of the functioning fovea and patients may be 
able to see only a portion of words when reading.  As the disease progresses to include the 
parafoveal region, central vision becomes affected.  Severe vision loss occurs when these 
areas of atrophy enlarge or coalesce and expand into the foveola.  In addition to the 
formation of scotomas that progress into the foveola, patients with geographic atrophy can 
experience a variety of visual symptoms such as distorted vision, trouble discerning colors, a 
slow recovery of visual function after exposure to bright light, a loss of contrast sensitivity 
and marked visual impairment in dimly lit environments (Sunness et al, 1997; 
Sunness et al, 2007; Sunness et al, 2008). 
Previous studies have reported atrophic lesion expansion rates that range between 1.3 and 
2.8 mm2 per year (Klein et al, 2007; Age-Related Eye Disease Study [AREDS] Research 
Group, 2009; Holz et al, 2007; Fritsche et al, 2008; Sunness et al, 1999; 
Schatz and McDonald, 1989).  While the majority of these studies have shown an association 
between the development of GA and systemic and environmental factors including blood 
pressure, smoking, heavy drinking status, body mass index, sedentary lifestyle, age, and 
gender, none of these studies have found an association between differences in intra-
individual lesion expansion rates and systemic or environmental risks.  In contrast to these 
findings, several natural history studies have identified a number of atrophic lesion 
characteristics that are associated with differences in lesion growth rates.  In a 5-year

follow-up of 32 patients with GA, Klein and collaborators (2008b) reported that lesion 
growth is more rapid in lesions with multiple areas of atrophy, ie, multifocal lesions.  Holz 
and colleagues have demonstrated that patterns of increased fundus autofluorescence (FAF) 
outside patches of GA also predict subsequent progression (Holz et al, 2007).  In the Age 
Related Eye Disease study, baseline lesion area was an important predictor of subsequent 
lesion growth (AREDS Research Group, 2009).  The GAP natural history study with baseline 
measurements from over 500 patients not only confirmed these associations between lesion 
phenotypic characteristics and lesion growth rates, but also reported that lesion growth is 
more rapid for extrafoveal lesions compared to foveal lesions (Holz et al, 2010).  In the 
current study (BEACON Study) patients with unifocal atrophic lesions, lesions in which the 
total lesion area is greater than 18 mm2 and lesions without perilesional hyperfluorescence 
will be excluded.  The expectation is that this reduction in lesion phenotypic variability will 
decrease the variability of lesion growth rates, decreasing the sample size required to 
demonstrate a treatment effect in a study that is using atrophic lesion growth as the primary 
efficacy variable. 
A number of genetic variants have been associated with both the neovascular and GA forms 
of advanced AMD.  These include variants in complement factor H (CFH), complement 
factor B (CFB), complement factor 2 (C2), complement factor 3 (C3), apolipoprotein E and 
the age related maculopathy susceptibility 2 (ARMS2) locus (Gold et al, 2006; 
Yates et al, 2007; Seddon et al, 2007; Seddon et al, 2009).  Of these CFH, C2, C3, CFB, and 
ARMS2 have been reported to predict the progression from intermediate to advanced AMD 
(Seddon et al, 2007; Francis et al, 2008).  Together these findings prompted 
Scholl et al (2009) and Klein et al (2010) to assess whether specific alleles at these gene loci 
were associated with the rate of atrophic lesion growth.  While these 2 studies confirmed the 
association of the high risk variants for CFH, C2, C3, and ARMS2 with the presence of GA, 
with the exception of ARMS2 in the study by Klein and colleagues (2010), there was no 
association between the high risk variants and atrophic lesion growth. 
The association between genetic variants and treatment response has also been evaluated in 
several studies of advanced AMD.  In a cohort of 397 patients the mean change in best 
corrected visual acuity (BCVA) following 3 intravitreal injections with ranibizumab was a 
10-letter gain in patients homozygous for the non-risk genotype for CFH and ARMS2; in 
comparison, there was no improvement in BCVA in the group of patients homozygous for 
the CFH and ARMS2 high risk alleles (Smailhodzic et al, 2012).  Similar findings have been 
reported in the ARED Study.  In an analysis of a subgroup of category 3 and 4 patients, ie, 
those with the greatest risk for the development of advanced AMD, there was an association 
between treatment response and genetic risk factors.  Within those patients homozygous for

the non-risk CFH allele, 34% treated with placebo versus 11% treated with anti-oxidants plus 
zinc progressed to advanced AMD.  Within those patients homozygous for the high-risk CFH 
allele, 44% of the placebo-treated patients and 39% of the antioxidant-plus-zinc-treated 
patients progressed to advanced AMD (Klein et al, 2008a).  In contrast to these findings, in 
the CATT (Comparison of AMD Treatments Trials) trial, which compared the treatment 
effects of ranibizumab and bevacizumab in 1185 patients with exudative AMD, there was no 
association between the genetic variants for CFH, C3 nor ARMS2 and the response to 
treatment (Hagstrom et al, 2013).  More specifically, there were no high risk alleles that 
predicted final BCVA or change in BCVA, the degree of anatomical response nor the 
number of intravitreal injections.  
In the BEACON study patients will be genotyped using a genome-wide array in an effort to 
uncover novel disease-associated genes.  The variance of lesion growth explained by 
genotyped markers will be analyzed according to standard methods (Fritsche et al, 2016).  A 
generally accepted genome-wide significance threshold will be adopted to determine if a 
variant (and thus a genetic locus) is significantly associated with GA lesion growth.   
In nearly all of the epidemiological and natural history studies of GA, disease progression 
has been based on lesion growth assessments that were derived from color fundus 
photographs (Davis et al, 2005; Klein et al, 2008b; Schatz and McDonald, 1989; 
Sunness et al, 1997; Sunness et al, 1999; Sunness et al, 2007).  With color fundus 
photography, lesion identification is based on an abrupt transition of fundus pigmentation 
which results from the atrophy of RPE cells.  Due to inter-patient variability of fundus 
pigmentation, media opacities, the presence of drusen and small satellites of atrophy, graders 
at reading centers have commonly reported difficulty with reproducibly measuring atrophic 
areas from color fundus photographs (Pirbhai et al, 2005; Scholl et al, 2003; 
Sunness et al, 1999).  An alternative approach for lesion area quantification, FAF imaging, 
has been used to quantify the progression of GA in a large multicenter study (Fundus 
Autofluorescence in Age-related Macular Degeneration [FAM] study) conducted in Germany 
(Bindewald et al, 2005; Holz et al, 2001; Holz et al, 2007; Schmitz-Valckenberg et al, 2006).  
With this technique imaging of atrophic lesions is based on the normal autofluorescence 
properties of RPE cells; the loss of RPE autofluorescence indicates disruption of the 
functional interaction between RPE and photoreceptor cells due to damage or death of 
photoreceptor cells and/or RPE cells (Schmitz-Valckenberg, 2009).  While the loss of these 
cells is also visualized with color fundus photography, lesion boundary discrimination 
appears to be improved with FAF imaging (Sunness et al, 1999; Schmitz-Valckenberg, 2009; 
Schmitz-Valckenberg et al, 2011).  Due to its increased boundary discrimination, FAF 
imaging will be used to evaluate the effect of brimonidine in the BEACON study.

Brimonidine (AGN-190342) is a selective alpha-2 adrenergic agonist with a long history of 
clinical use in the treatment of patients with ocular hypertension and open-angle glaucoma.  
Beyond its intraocular pressure (IOP)-lowering effect, brimonidine has also been reported to 
have cyto/neuroprotective effects (Evans et al, 2003; Tsai and Chang, 2005).  It is postulated 
that the neuroprotective effect of brimonidine is mediated by activation of the alpha-2 
adrenoceptor which is expressed throughout the neurosensory retina and is involved in 
pathways that inhibit apoptosis.  In preliminary data from a rat model of retinal degeneration, 
systemic administration of brimonidine protected photoreceptors from photo-oxidative 
damage, as assessed with optical coherence tomography (OCT) and preserved photoreceptor 
function, as assessed with full-field electroretinography.  The neuroprotective effects of 
brimonidine have also been observed in animal models of retinal vein occlusion, retinal 
ischemia and retinal detachment.  Cytoprotective effects of brimonidine have been 
demonstrated in vitro, in human RPE (ARPE-19 cell line) and Müller cells (MIO-M1 cell 
line) (Ramírez et al, 2016).  The use of brimonidine to preserve structural and functional 
capacity as demonstrated in animals may provide a novel mechanism for reducing the risk of 
retinal degeneration in human diseases such geographic atrophy. 
Brimonidine solution administered by intravitreal injection has a vitreal half-life of 
approximately 1.45 hours.  Sustained retinal drug concentrations of brimonidine can be 
achieved when the drug is formulated into a solid implant composed of a biodegradable 
poly-D,L-lactide (PLA) and poly-D,L-lactide-co-glycolide polymer (PLGA) matrix and 
injected into the vitreous using the Novadur drug delivery system (DDS®).  A formulation of 
this product using brimonidine tartrate salt (Brimonidine Tartrate Posterior Segment DDS or 
Brimonidine DDS [Generation 1]) has been used in animal studies and in clinical Phase 1 
and Phase 2 studies. 
In these human clinical studies Brimonidine DDS (Generation 1) (132 µg or 264 µg) was 
well tolerated (Studies 190342-028D, 190342-030D, 190342-031D, 190342-036, and 
190342-032D).  The majority of the treatment-related adverse effects were ocular and were 
attributed in large part to the injection procedure; the most frequently reported treatment-
related adverse effects were conjunctival hemorrhage and conjunctival hyperemia. 
Study 190342-032D investigated the use of Brimonidine DDS (Generation 1) (132 µg or 
264 µg) compared with a Sham treatment in 117 patients with GA secondary to AMD; 
treatments with the sustained release formulation or Sham treatment were administered at the 
baseline visit and at the month 6 visit.  In this study the safety profile was not different from 
that in clinical studies with a single injection.  Three months after the first injection, the 
increase in atrophic lesion size was significantly smaller, p ≤ 0.032, in both brimonidine-

treated groups compared with the Sham group; however, at the 12-month timepoint there 
were no between-group differences in lesion growth rates.  The lack of statistical significance 
at the later timepoint may have been a consequence of the small sample size, the phenotypic 
heterogeneity of the patient population and/or the advanced stage of disease within the 
patient population.  It is also conceivable that the dose and dosing frequency may have been 
insufficient to sustain an effective drug concentration in the retina. 
To address this latter issue vitreous brimonidine levels were quantified over an 8-week time 
period in patients receiving 132 µg or 264 µg Brimonidine DDS (Generation 1) and then 
undergoing a pars plana vitrectomy (Study 190342-036).  A pharmacokinetic model was then 
constructed based on these clinical data along with vitreous and retinal concentrations in 
monkeys treated with the Brimonidine DDS (Generation 1).  Based on the pharmacokinetic 
model, retinal levels in man achieved with the Brimonidine DDS (Generation 1) were 
equivalent to those that preserved photoreceptor function in the acute model of photo-
oxidative damage but only for 30 to 40 days after administration of the implant.  
To support further studies in patients with GA, a new brimonidine sustained-release 
formulation has been developed (Brimonidine Posterior Segment Drug Delivery System 
[Brimonidine DDS (Generation 2)], hereafter called Brimo DDS).  By changing the active 
ingredient from the tartrate salt to the free base, a 50% higher implant drug load can be 
achieved.  Changing the PLGA/PLA polymer blend created a more rapid degradation of the 
polymer matrix, which achieves not only a more rapid release of brimonidine, but also higher 
retinal levels.  With this new formulation, 4 months after administration of the 400-µg 
implant, macular concentrations of brimonidine in monkeys were 2-fold above the effective 
retina concentration in the acute photo-oxidative model.  Pharmacokinetic/pharmacodynamic 
modeling suggests that dosing every 3 months will maintain brimonidine concentrations in 
the retina that are equivalent to the concentrations that protected photoreceptors in an acute 
photo-oxidative model of retinal degeneration. 
In addition to the modified drug formulation, the size of the implants was modified to permit 
their delivery with a smaller needle, ie, a 25-gauge compared with a 22-gauge needle in the 
previous formulation.  Using a smaller needle for implant delivery is expected to result in 
fewer injection-related adverse events, greater patient comfort, and a better product safety 
profile. 
The cyto/neuroprotective effects of Brimonidine DDS (Generation 1) observed in animal 
studies, as well as the safety and effectiveness reported in human studies, suggest that 
brimonidine has the potential for slowing disease progression in patients with geographic

atrophy secondary to AMD.  The improvements in the formulation and the reduction of inter-
patient phenotypic variability, as well as the use of newer ocular imaging modalities, may 
allow better detection of an efficacy signal in this population.  Atrophic lesion area will be 
measured using FAF and correlated with spectral-domain optical coherence tomography (SD-
OCT).  The combination of these imaging modalities will provide both quantitative and 
qualitative assessments of lesion progression.  Structural measurements will be supplemented 
with assessment of photoreceptor function using microperimetry, facilitating correlations 
between functional and structural degeneration at precise areas of the retina.  Genotypic 
analysis will be performed to provide a greater understanding of the relationship between 
specific genes variants and their association with GA progression and/or treatment benefit.

Study Objectives and Clinical Hypotheses 
2.1 
Study Objectives 
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 FAF images; (3) the effects of 
treatment on the mean change in low luminance 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 quantified using scotopic/mesopic microperimetry; and (6) to characterize the 
systemic pharmacokinetic profile of Brimo DDS.  
2.2 
Clinical Hypotheses 
The clinical hypotheses are that: 
• Brimo DDS is safe and well tolerated with repeated intravitreal administration in patients 
with GA secondary to AMD as assessed by the incidence of adverse events 
• Brimo DDS is more effective than Sham treatment in slowing the growth of atrophic 
lesion area and the loss of standard and low luminance BCVA 
3 
Study Design 
This is a multicenter, double-masked, randomized, Sham treatment-controlled, 30-month 
phase 2b study designed to evaluate the safety and efficacy of Brimo DDS in patients with 
GA secondary to AMD.  Patients will be randomized in a 1:1 ratio to receive 400 µg Brimo 
DDS, administered by intravitreal injection, or Sham treatment (control).  The study 
medication will be administered every 3 months from Baseline (Day 1) through Month 21.  
The primary efficacy measure, the mean change in atrophic lesion area as assessed with FAF 
will be assessed at Month 24.  In addition to quantifying structural changes of the retina,

functional assessments will be performed using scotopic/mesopic microperimetry, as well as 
standard and low luminance BCVA.  Total duration of the study for each patient is 30 months 
following randomization/treatment.  
 
  
For patients who do not participate in the microperimetry procedure or patients from sites not 
participating in the microperimetry procedure, there will be only 1 Screening visit, and 
therefore 13 visits over the study duration. 
 
3.1 
Data Review Committee 
A Data Review Committee (DRC) consisting of physicians and trained study personnel, in 
addition to ad hoc internal/external experts, will assess study treatment effects throughout the 
study; these assessments will include a review of unmasked safety data and biodegradation of 
the implant to determine the appropriateness of continuing dosing and enrollment.  The 
composition and activities of the committee are described in the DRC charter, a separate 
document.

Study Population and Entry Criteria 
4.1 
Number of Patients  
Approximately 300 patients (150 per treatment group) will be enrolled in the study at 
approximately 40 sites.  Two hundred forty patients are expected to reach Month 24 for the 
primary endpoint assessment.  The anticipated dropout rate is 20%. 
4.2 
Study Population Characteristics 
To avoid selection bias, the investigator should ensure that all persons who meet the 
following inclusion and exclusion criteria are offered enrollment in the study.  To ensure that 
the study population will be representative of all eligible patients, no additional exclusions 
can be applied by the investigator.  Selection of patients will exclude all considerations of 
race, occupation, socioeconomic status, and gender.  If both eyes meet all of the 
inclusion/exclusion criteria, the eye with the worst standard BCVA will be selected as the 
study eye.  If both eyes meet all of the inclusion/exclusion criteria and BCVA values are 
identical for both eyes, the right eye will be selected as the study eye.

Permissible and Prohibited Medications/Treatments 
4.5.1 
Permissible Medications/Treatments 
Therapy considered necessary for the patient’s welfare may be given at the discretion of the 
investigator.  All medications and procedures should be recorded in the electronic case report 
form (eCRF).  If the permissibility of a specific medication/treatment is in question, please 
contact Allergan.  
Use of the following medications is permissible during the study: 
• Alpha-1 antagonists (eg, prazosin, terazosin, doxazosin, labetolol) and other selective 
alpha-antagonists that do not inhibit alpha-2 adrenoceptors 
• Non-ocular use of alpha-2 agonists and alpha-2 antagonists are permissible if used for at 
least 30 days prior to Baseline, and the use of the medication is expected to remain stable 
(dose and dosing regimen) for the duration of the study.  Any changes to such 
medications should be documented on the appropriate eCRFs. 
YAG capsulotomy is recommended to be scheduled no sooner than 2 to 3 weeks before a 
scheduled Brimo DDS injection, or at least 2 to 3 weeks after a Brimo DDS injection. The 
YAG opening should be kept slightly smaller than the periphery of the IOL optic to reduce 
the chance that the Brimo DDS implants will migrate from the vitreous cavity to the anterior 
chamber. 
In case of retinal tear, withhold the study treatment until the tear is successfully treated and 
resolved. Treatment may be re-initiated later at the investigator’s discretion and if the patient 
does not meet any of the discontinuation criteria in Section
 
   
If a patient develops choroidal neovascularization in the fellow eye, study treatment can 
continue in the study eye. The fellow eye should be treated according to best medical 
practice. 
If cataract surgery is necessary, attempt to schedule cataract surgery ≥ 7 days after the most 
recent study treatment. Study treatment may be resumed ≥ 14 days after cataract surgery, 
assuming no surgery-related complications.

Definition of Females of (Non-) Childbearing Potential and 
Acceptable Contraceptive Methods 
For purposes of this study, females will be considered of childbearing potential unless they 
are naturally postmenopausal or permanently sterilized (ie, hysterectomy).  Natural 
menopause is defined as the permanent cessation of menstrual periods, determined 
retrospectively after a woman has experienced 12 months of amenorrhea without any other 
obvious pathological or physiological cause.  For women of childbearing potential who may 
participate in the study, the following methods of contraception, if properly used, are 
generally considered reliable: hormonal contraceptives (ie, oral, patch, injection, implant), 
male condom with intravaginal spermicide, diaphragm or cervical cap with spermicide, 
vaginal contraceptive ring, intrauterine device, surgical sterilization (bilateral tubal ligation, 
bilateral salpingectomy), vasectomized partner, or sexual abstinence. 
The investigator and each patient will determine the appropriate method of contraception for 
the patient during the participation in the study. 
If a female becomes pregnant during the study, the investigator will notify Allergan 
immediately after the pregnancy is confirmed and the patient will be exited from the study 
after appropriate safety follow-up.  The investigator will (1) notify the patient’s physician 
that the patient was being treated with an investigational drug (Brimo DDS or Sham) and 
(2) follow the progress of the pregnancy.  The investigator should document the outcome of 
the pregnancy and provide a copy of the documentation to Allergan. 
4.5.3 
Prohibited Medications/Treatments 
The decision to administer a prohibited medication/treatment is done with the safety of the 
study participant as the primary consideration.  When possible, Allergan should be notified 
before the prohibited medication/treatment is administered.  Use of the following 
medications is prohibited during the study: 
• Any periocular injection or intravitreally injected therapy  
• Ocular use (other than the study medication) of brimonidine, apraclonidine, 
oxymetazoline, naphazoline, tetrahydrozoline, or any other medications with known 
alpha-2 agonist activity  
• Inconsistent or intermittent use of systemic medications with known alpha-2 antagonism 
(eg, phentolamine, phenoxybenzamine, yohimbine, risperidone) or medications with 
known alpha-2 agonism (eg, methyldopa, clonidine, guanfacine, tizanidine) 
• Use of roflumilast (Daliresp®) or other oral phosphodiesterase-4 inhibitors

scotopic/mesopic microperimetry will be certified.  Certification by the CRC of the 
equipment and examiners at each investigative site will occur prior to patient screening.  
6.4.2 
Standard and Low Luminance Best Corrected Visual Acuity 
Standard BCVA will be quantified using the ETDRS visual acuity protocol.  BCVA testing 
should precede any examination requiring contact with the eye.  BCVA should be performed 
following manifest refraction.  Low luminance BCVA will be measured using 2.0 log unit 
neutral density filter and the ETDRS visual acuity protocol.  Certification and procedures for 
performing the standard and low luminance BCVA measurements are included in the 
Procedure Manual.   
6.4.3 
Spectral-domain Optical Coherence Tomography 
SD-OCT images collected in the study may be collected only with the 
 
  A standardized procedure for obtaining  SD-OCT images using

Procedure Manual.  SD-OCT images from each of the specified study visit will be sent to the 
CRC; images from the Screening Visit 1 will be used to define foveal involvement and 
patient eligibility as confirmed by the CRC. 
6.4.4 
Microperimetry 
Scotopic/mesopic microperimetry will be performed at selected sites.  Patients at these sites 
can enroll into the study if they decline to participate in the scotopic/mesopic microperimetry 
assessments, or if they do not meet inclusion criterion #9 (Section 4.3).  Scotopic/mesopic 
microperimetry assessments may only be performed with the Nidek MP-1 Scotopic (MP-1S) 
microperimeter.  A customized procedure for microperimetry using the Nidek MP-1S is 
included in the Procedure Manual.  Nidek MP-1S images will be sent to the CRC. 
The reproducibility of the mean retinal sensitivity threshold measurements from the repeat 
assessment performed during the Screening Visit 2 will be used to evaluate patient eligibility 
for the microperimetry procedure, as confirmed by the CRC.  The Nidek MP-1S image-
assessment report from each visit, beginning with the Baseline visit, will be submitted to the 
CRC; these reports will include the fundus images submitted in an uncompressed format.

Other Study Supplies 
Allergan will make provisions (directly or indirectly) to supply the study sites with 
pregnancy test kits; ETDRS instrumentation (if needed); medications or supplies (eg, anti-
infective ophthalmic solution, local anesthetic eye drop, dilating eye drop, povidone iodine, 
syringe, needles, cotton tip swabs, cellulose sponges), and blood sampling kits for 
pharmacokinetic analysis (at selected sites), genotyping, and gene expression.  Tubes for 
collection of samples for clinical laboratory analysis will be provided by a central laboratory. 
6.6 
Summary of Methods of Data Collection 
Clinical data for this study will be collected in eCRFs using the Phase Forward Inform 
System.  Data entered into the eCRF will correspond to and be supported by source 
documentation maintained at the site.  Data will be transferred to Allergan from the CRC and 
genotyping laboratory. 
7 
Statistical Procedures 
The primary analysis for efficacy will be based on data collected through Month 24.  An 
interim analysis may be performed after 50% of patients complete the Month 18 visit.  Up to 
3 database locks are planned for the study:  an interim lock at Month 18 (50% of patients), 
the primary lock at Month 24, and the final lock at the end of the study (Month 30). 
Statistical methods for data analyses will be detailed in the analysis plan as a separate 
document which will be finalized prior to the first interim lock. 
7.1 
Analysis Populations 
The following 2 populations will be used for statistical analyses:  modified intent-to-treat 
(mITT) and safety. 
The mITT population will include all randomized and treated patients with Baseline and at 
least one post-baseline measurement for the atrophic lesion area.  The mITT population will 
be used for analyses of efficacy variables.  The safety population will include all treated 
patients and will be used for safety analyses.  All analyses will be performed based on the 
randomized treatment.

Collection and Derivation of Primary and Secondary Efficacy 
Assessments 
The primary efficacy measure in this study is the atrophic lesion area measured by FAF 
examination.  The primary timepoint for the efficacy analysis is Month 24.   
7.2.1 
Primary Efficacy Variable 
The primary efficacy variable is the change from Baseline in the atrophic lesion area in the 
study eye, assessed with FAF and quantified by the CRC.  
7.2.2 
Secondary Efficacy Variables 
The secondary efficacy variables are (1) change from Baseline in low luminance BCVA in 
the study eye as assessed using a 2.0 log unit neutral density filter and the ETDRS visual 
acuity protocol (2) change from Baseline in standard BCVA in the study eye as assessed with 
the ETDRS visual acuity protocol.  
7.3 
Hypothesis and Methods of Analysis 
7.3.1 
Primary Efficacy Analyses 
The primary efficacy variable is the change from Baseline in atrophic lesion area in the study 
eye.  The primary analysis will use the mITT population and will be based on a mixed model 
for repeated measures (MMRM) that includes treatment, study region (North America, 
Europe, and Australia), analysis visit, and treatment-by-visit interaction as factors as well as 
the baseline value and baseline value-by-analysis visit interaction as covariates.  The least-
squares means (LS means) for change from baseline will be calculated for each group.  
Statistical test for the between-group difference (Brimo DDS versus Sham) in LS means and 
the construction of the corresponding 2-sided 95% confidence intervals will be done using 
the same MMRM model.  If warranted, data transformation will be applied to the effective 
diameter (ED) (such as the square root transformation), and the final statistical analysis for 
the change from baseline will be based on the transformed data. 
7.3.2 
Secondary Efficacy Analyses 
Analysis of data collected for both standard and low luminance BCVA will include change 
from baseline in BCVA scores as the number of letters read correctly and categorical change 
in BCVA.

7.3.4 
Safety Analyses 
Statistical analysis for safety will be based on the safety population.  The Medical Dictionary 
for Regulatory Activities (MedDRA) nomenclature will be used to code adverse events and 
biomicroscopy and ophthalmoscopy data.  The number and percent of patients reporting 
adverse events will be tabulated by primary system organ class, preferred term, and severity.  
The summary tables will be generated separately for adverse events reported during the 
screening to baseline period (pre-treatment adverse events) and treatment period (treatment-
emergent adverse events [TEAEs]).  Summaries for TEAEs will be organized into the 
following:  all adverse events regardless of causality; treatment-related adverse events; ocular 
adverse events in the study eye; treatment-related ocular adverse events in the study eye; and 
primary safety measures as outlined in Section 6.3.  Group comparisons will be done using a 
chi-square test or Fisher’s exact test as appropriate. 
 
 
 
 
 
7.4 
Subgroup Analyses 
Analyses of subgroups defined by important baseline disease characteristics (such as lesion 
size), will be performed, if applicable.

7.5 
Sample Size Calculation 
A standard method for measuring disease progression in patients with GA secondary to AMD 
is to quantify the expansion rate of the areas of atrophy.  Over a 12-month period this 
expansion rate typically ranges between 1 and 2 mm2 (Sunness et al, 2007; Holz et al, 2007; 
Holz et al, 2010).  The atrophic lesion expansion rate used in the sample size calculation for 
the current study was from the GAP study (Holz et al, 2010).  The selection of the GAP data 
was based on the large patient population in this natural history study and because of the 
similarities between the GAP study and the current study in both study design and patient 
populations.   
The 12-month lesion expansion rate from the GAP study was 1.73 mm2.  A projected 
24-month expansion rate, 2.8 mm2, was calculated by applying a 20% discount to a linear 
extrapolation of the GAP lesion expansion data.  Based on this lesion expansion rate and 
assuming a common standard deviation of 1.65 mm2, a 2-sided t-test with 90% power and an 
alpha of 0.05 will require a sample size of 120 patients per group to detect a 25% reduction 
from the Sham treatment.  A 25% reduction from the Sham treatment corresponds to a 
treatment difference of 0.70 mm2.  With an anticipated dropout rate of 20%, approximately 
300 patients will be enrolled such that 240 (120 per group) will complete the Month 24 visit. 
The sample size calculations are based on the procedure MTTO-1 in nQuery (v6.01). 
7.6 
Interim Analyses 
An interim analysis may be performed after 50% of patients have completed the Month 18 
visit or have exited early from the study.  To maintain an overall Type I error rate at 0.05 
level, the significance level will be 0.001 for the interim analysis at Month 18 and 0.05 
(Haybittle–Peto method) for the Month 24 analysis.  The purpose of the interim analysis is to 
support the decision making process and the planning of further development. 
To maintain the integrity of the study, individuals who are directly involved in study conduct 
and data management will remain masked to treatment assignment of individual patients until 
study completion.

Patient Entry Procedures  
8.1.1 
Overview of Entry Procedures 
Prospective patients as defined by the criteria in Sections 4.3 and 4.4 (inclusion/exclusion 
criteria) will be considered for entry into this study. 
8.1.2 
Informed Consent and Patient Privacy 
The study will be discussed with the patient and a patient wishing to participate must give 
informed consent prior to any study-related procedures or change in treatment.  The patient 
must also give authorization (US only), data protection consent (Europe only), and other 
written documentation in accordance with the relevant country and local privacy 
requirements (where applicable) prior to any study-related procedures or change in treatment.   
Each patient who provides informed consent will be assigned a patient number that will be 
used on patient documentation throughout the study.   
8.2 
Procedures for Final Study Entry 
Patient eligibility based on lesion characteristics, as well as the reproducibility of the retinal 
sensitivity measurements, must be confirmed by the CRC prior to patient randomization.  
Patients at sites participating in scotopic/mesopic microperimetry can enroll into the study if 
they decline to participate in the microperimetry procedure , or if they do not meet inclusion 
criterion #9 (Section 4.3).  In addition, all screening laboratory tests must be performed, and 
the results must be evaluated and determined to be acceptable to the investigator prior to 
patient randomization into the study.  Screening laboratory tests may be repeated once at the 
discretion of the investigator or Allergan. 
Female patients of childbearing potential must have a negative pregnancy test result prior to 
entry into the study. 
A patient is considered to have entered the study at the time of randomization to treatment on 
Day 1.  See Section 5.5 for the method for assignment to treatment groups/randomization.

Patients who develop neovascular AMD must be discontinued.  Any patient who develops a 
concomitant retinal disorder in the study eye that prevents retinal visualization and 
quantification of the area of atrophic lesions, or causes a sustained ≥ 30 letter loss of BCVA 
(a sustained loss is defined as a loss evident on 2 consecutive study visits) must be 
discontinued. 
For patients who discontinue from the study early, every effort should be made to have these 
patients return to the clinical center for completion of the exit visit.  Additionally, patients 
who discontinue from the study early should be encouraged to return to the clinical center for 
an ophthalmological evaluation 12 weeks after their most recent study treatment.  Adverse 
events leading to patient early discontinuation must be followed-up as appropriate. 
8.7.1 
Treatment Failures 
Allergan considers the benefit-risk of study participation to be positive, and does not 
recommend study discontinuation due to treatment failure.  Currently, there are no approved 
treatments for GA, and consequently there are no standard-of-care treatment options 
available for patients who fail study treatments.  Further, inclusion of treatment failure 
criteria in a masked study may introduce bias.  As an example, treatment failure criteria 
based on lesion progression may apply unequally by treatment assignment (Sham versus 
active), where potentially more Sham-treated patients would be identified as treatment 
failures.  Likewise, removal of patients who fail active treatment would also create a bias 
towards the appearance of more significant study drug effects. 
Results from clinical studies to date suggest a positive benefit-risk profile of the study 
treatment.  The Phase 2a clinical study 190342-032D results in patients with GA suggest a 
modest effect of Brimo DDS.  In the 190342-032D study, patients treated with Brimo DDS 
(Generation 1) 264 µg experienced a 27.4% reduction in GA progression rate at the 12-month 
primary timepoint compared with sham-treated patients.  Exploratory analysis of these data 
(Kuppermann et al, 2017) indicates that the effects of Brimo DDS may be even larger in a 
subpopulation of fast-progressing patients (defined as patients with baseline GA ≥ 9 mm2).  
Reductions in progression rate in this subpopulation were nearly 38% and this effect was 
statistically significant.  As a progressive disease, continuation of treatment may be necessary 
to realize a clinically meaningful outcome on disease progression.  Clinical study safety 
results to date, including a long-term safety study, suggest that Brimo DDS is well tolerated, 
and risks associated with the study treatment are mainly related to the intravitreal injection.  
Likewise, patients randomized to Sham have no increased risk with additional Sham 
treatments, as these are needleless.  Given these considerations, Allergan considers the

preponderance of evidence to favor study participation, as compared with absence of 
treatment.  Therefore, criteria for treatment failure are not included in this protocol. 
8.8 
Study Termination 
The study may be stopped at his/her study site at any time by the site investigator.  Allergan 
may stop the study (and/or the study site) for any reason with appropriate notification.  
9 
Adverse Events  
Adverse events occurring during the study will be recorded on an adverse event eCRF.  If 
adverse events occur, the first concern will be the safety of the study participants.  
9.1 
Definitions 
9.1.1 
Adverse Event 
An adverse event is any untoward medical occurrence in a patient or clinical investigation 
subject administered a pharmaceutical product and that does not necessarily have a causal 
relationship with this treatment.  An adverse event can therefore be any unfavorable and 
unintended sign (including an abnormal laboratory finding), symptom, or disease temporally 
associated with the use of a medicinal (investigational) product, whether or not related to the 
medicinal (investigational) product.  In addition, during the screening period, adverse events 
will be assessed regardless of the administration of a pharmaceutical product.   
Progression of the treatment indication, including new or worsening of anticipated clinical 
signs or symptoms, which are collected as clinical efficacy variables and assessed as 
unequivocally associated with the disease progression and/or lack of efficacy, should not be 
reported as adverse events unless the disease progression is greater than anticipated in the 
natural course of the disease. 
Note:  Adverse events must be collected once informed consent has been obtained, regardless 
of whether or not the patient has been administered study drug. 
Adverse events will be assessed, documented, and recorded in the eCRF throughout the study 
(ie, after informed consent has been obtained).  At each visit, the investigator will begin by 
querying for adverse events by asking each patient a general, non-directed question such as 
“How have you been feeling since the last visit?”  Directed questioning and examination will 
then be done as appropriate.  All reported adverse events will be documented on the 
appropriate CRF.

9.1.2 
Serious Adverse Event 
A serious adverse event is any adverse event occurring at any dose that results in any of the 
following outcomes:  death, a life-threatening adverse event, inpatient hospitalization or 
prolongation of existing hospitalization, a persistent or significant disability/incapacity, or a 
congenital anomaly/birth defect.  Important medical events that may not result in death, be 
life threatening, or require hospitalization may be considered a serious adverse event when, 
based upon appropriate medical judgment, they may jeopardize the patient or subject and 
may require medical or surgical intervention to prevent one of the outcomes listed in this 
definition.  (See Section 9.3 for procedures for reporting a serious adverse event.) 
Allergan considers all cancer adverse events as serious adverse events.  In addition, Allergan 
considers any abortion (spontaneous or nonspontaneous) as a serious adverse event. 
Pre-planned surgeries or procedures for pre-existing, known medical conditions for which a 
patient requires hospitalization are not reportable as serious adverse events. 
Any pre-planned surgery or procedure should be clearly documented in the site source 
documents by the medically qualified investigator at the time of the patient’s entry into the 
study.  If it has not been documented at the time of the patient’s entry into the study, then it 
should be documented as a serious adverse event and reported to Allergan. 
9.1.3 
Severity 
A clinical determination will be made of the intensity of an adverse event.  The severity 
assessment for a clinical adverse event must be completed using the following definitions as 
guidelines: 
Mild 
Awareness of sign or symptom, but easily tolerated. 
Moderate 
Discomfort enough to cause interference with usual activity. 
Severe 
Incapacitating with inability to work or do usual activity. 
Not applicable 
In some cases, an adverse event may be an “all or nothing” finding 
which cannot be graded. 
 
9.1.4 
Relationship to Study Drug or Study Procedure 
A determination will be made of the relationship (if any) between an adverse event and the 
study drug or study procedure, as applicable.  A causal relationship is present if a

determination is made that there is a reasonable possibility that the adverse event may have 
been caused by the drug or study procedure.   
Note:  a study procedure occurring during the screening/baseline period can include a 
washout of medication or introduction of a run-in medication or study required diagnostic 
procedure.   
For treatment-related adverse events, the investigator will note on the eCRF whether the 
event is related to the study drug (DDS) and/or the applicator, and/or the insertion procedure. 
9.2 
Procedures for Reporting Adverse Events 
Any adverse event must be recorded on the appropriate CRF. 
All adverse events that are drug-related and unexpected (not listed as treatment-related in the 
current Investigator’s Brochure) must be reported to the governing Institutional Review 
Board/Independent Ethics Committee (IRB/IEC) as required by the IRB/IEC, local 
regulations, and the governing health authorities.  Any adverse event that is marked 
“ongoing” at the exit visit must be followed-up as appropriate. 
9.3 
Procedures for Reporting a Serious Adverse Event 
Any serious adverse event occurring during the study period (beginning with informed 
consent) and any serious ocular adverse event occurring within 4 months after the last dose 
of study treatment must be immediately reported but no later than 24 hours after learning of a 
serious adverse event.   
Serious adverse events must be reported to Allergan as listed on the Allergan Study Contacts 
Page and recorded on the serious adverse event form.  All patients with a serious adverse 
event must be followed up and the outcomes reported.  The investigator must supply Allergan 
and the IRB/IEC with any additional requested information (eg, autopsy reports and 
discharge summaries).  
In the event of a serious adverse event, the investigator must: 
1. Notify Allergan immediately by fax or email using the serious adverse event form 
(contact details can be found on page 1 of the serious adverse event form; phone numbers 
and relevant Allergan personnel contacts are also on the front page of protocol). 
2. Obtain and maintain in his/her files all pertinent medical records, information, and 
medical judgments from colleagues who assisted in the treatment and follow-up of the 
patient.

3. Provide Allergan with a complete, written description of the adverse event(s) on the 
serious adverse event form describing the event chronologically, including any treatment 
given (eg, medications administered, procedures performed) for the adverse event(s).  
Summarize relevant clinical information about the event:  signs, symptoms, diagnosis, 
clinical course and relevant clinical laboratory tests, etc.  Include any additional or 
alternative explanations for the causality which includes a statement as to whether the 
event was or was not related to the use of the investigational drug. 
4. Promptly inform the governing IRB/IEC of the serious adverse event as required by the 
IRB/IEC, local regulations, and the governing health authorities. 
9.4 
Procedures for Unmasking of Study Medication 
When necessary for the safety and proper treatment of the patient, the investigator can 
unmask the patient’s treatment assignment to determine which treatment has been assigned 
and institute appropriate follow-up care.  When possible, the Allergan Medical Safety 
Physician should be notified prior to unmasking study medication.  The investigator should 
inform the Allergan Medical Safety Physician of the unmasking if there is no notification 
prior to the unmasking.   
The treatment assignment for the patient can be determined by designated site personnel 
calling into the IVRS or IWRS system via password protected access.  The reason for 
breaking the code must be recorded in the patient’s source documents. 
10 
Administrative Items 
This protocol is to be conducted in accordance with the applicable Good Clinical Practice 
(GCP) regulations and guidelines, eg, the International Conference on Harmonisation (ICH) 
Guideline on GCP. 
10.1 
Protection of Human Patients 
10.1.1 
Compliance With Informed Consent Regulations (US 21 CFR 
Part 50) and Relevant Country Regulations 
Written informed consent is to be obtained from each patient prior to any study-related 
activities or procedures in the study, and/or from the patient’s legally authorized 
representative.  If the patient is under the legal age of consent, the consent form must be 
signed by the legally authorized representative in accordance with the relevant country and 
local regulatory requirements.

Section 
Revision 
Rationale 
Section 8.8 
Removed language about treatment failures and 
deleted section; added new section 8.7.1 to 
provide rationale for not discontinuing patients 
due to treatment failure 
 
Potential for bias as more sham 
patients may be removed for 
treatment failure; hurts potential 
to realize a treatment difference 
between sham and Brimo DDS; 
there are no available 
treatments to which patients can 
escape 
Section 10.4.1 
Removed references to printouts for source 
documents 
Only electronic versions are 
needed 
Section 11

Introduction 
This statistical analysis plan (SAP) details comprehensive, technical specifications of the 
statistical analyses of the efficacy and safety data outlined and/or specified in the final protocol 
of Study 190342-038 (BEACON) and the most recent amendment (version 7). Specifications of 
tables, figures, and data listings are contained in a separate document. The SAP for 
microperimetry 
 fundus autofluorescence (FAF) signal intensity, 
pharmacokinetic/pharmacodynamics (Blood samples for PK), genomic analysis (Blood Samples 
for Genotypic Analysis and Gene Expression Analysis) and health economics and health 
outcomes research data
 will be prepared 
separately. 
This document is organized into 3 main sections: 
1. Study overview 
2. Statistical Methodology and Study Endpoints 
3. Data Handling and Analysis Conventions  
4.1 
Study Design Summary 
4.1.1 
Overall Design 
This is a multicenter, double-masked, randomized, Sham treatment-controlled, 30-month phase 
2b study designed to evaluate the safety and efficacy of Brimo DDS in patients with geographic 
atrophy (GA) secondary to age-related macular degeneration (AMD). Patients will be 
randomized in a 1:1 ratio to receive 400 µg Brimo DDS, administered by intravitreal injection, or 
Sham treatment (control). Randomization will be stratified by region (North America, Europe, 
and Australia) and by atrophic lesion area (≤ 8 mm2 versus > 8 mm2) in the study eye as assessed 
by FAF examination at Screening Visit 1 and quantified by the Central Reading Center (CRC). 
The study medication will be administered every 3 months from Baseline (Day 1) through Month 
21. 
The primary efficacy measure, the mean change in atrophic lesion area as assessed with FAF, 
will be assessed at Month 24. In addition to quantifying structural changes of the retina, 
functional assessments will be performed using scotopic/mesopic microperimetry, as well as 
standard and low luminance Best-corrected visual acuity  (BCVA) evaluations. Total duration of 
the study for each patient is 30 months following randomization/treatment. 
 
 
For patients who do not participate in the microperimetry procedure or patients from sites not 
participating in the microperimetry procedure, there will be only 1 Screening visit, and therefore 
13 visits over the study duration.  
4.1.2 
Number of Participants 
According to the study protocol, approximately 300 patients (150 per treatment group) will be 
enrolled in the study at approximately 40 sites. Two hundred forty patients are expected to reach 
Month 24 for the primary endpoint assessment. The anticipated dropout rate is 20%.

From the patient enrollment monitoring as of September, 2016, total 310 patients were enrolled. 
Assuming approximately 25% dropout rate based on the survival analysis using Kaplan-Meier 
estimate, 310 patients will be enough that 240 patients complete the Month 24 visit. 
4.2 
Study Objectives and Endpoints 
Each study objective is presented with corresponding endpoint(s) below: 
Objectives 
Endpoints 
• To compare the efficacy of Brimo DDS with

Statistical Methods Planned in the Protocol and Determination of 
Sample Size 
This statistical analysis plan (SAP) will be approved prior to database lock. The SAP expands the 
statistical section of the protocol and contains a detailed description of methods to analyze data 
collected in the study. The text portion of the SAP will be included in the CSR report as 
Appendix 16.1.9.  
5.1.1

Safety 
All patients who received ≥ 1 administration of study treatment 
As treated 
If a patient is mis-stratified at the randomization, then the patient will be analyzed using the intended stratum in 
which the patient should belong to. 
5.1.1.1.2 
Study Treatments 
The following treatment groups are defined for this study: 
• Brimo DDS 400 µg 
• Sham 
5.1.1.1.3 
Statistical Methodology 
The methodologies defined below apply as specified to individual endpoints defined in this SAP. 
When indicated, two-sided 95% confidence intervals and two-sided p-values will be presented. 
Individual endpoint analyses may specify exceptions (additions or deletions) to these general 
definitions.

The model includes treatment, study region (North America, Europe, and 
Australia), analysis visit, and treatment-by-visit interaction as factors as well as 
the baseline value and baseline value-by-analysis visit interaction as covariates. 
An unstructured (co)variance structure shared across treatment groups was used 
to model the within-patient errors (compound symmetry if convergence fails). 
The Kenward-Roger approximation was used to estimate denominator degrees of 
freedom and adjust standard errors. Analyses were implemented with SAS PROC 
MIXED. The following is the sample SAS codes.

Best Corrected Visual Acuity Analyses 
Visual acuity will be recorded on the CRF as the number of letters correctly read. For a given 
eye, the 4-meter distance (standard) of visual acuity is tested first. If the patient correctly reads at 
least 20 letters at 4 meters, the visual acuity score will be set as the sum of 30 and the number of 
letters read correctly. If the patient correctly reads less than 20 letters at 4 meters, the visual 
acuity is measured again at 1 meter. The visual acuity score will be set to the number of letters 
read correctly at 1 meter plus the number of letters read correctly at 4 meters.

Retinal sensitivity thresholds in the study eye are measured by MP-1S Microperimetry using a 
grid with 56 stimulus points at baseline, Month 6, 12, 18, 24 and 30.  For each subject at each 
visit, the mean retinal sensitivity by one of the three neutral density filters (0, 1.0, 2.0) is recorded 
on the CRF. The mean retinal sensitivity data will be analyzed by each of the three neutral 
density filters and well as the numeric correction. Correction to the retinal sensitivity values will 
be conducted as follows: if neutral density filter is 0, then keep the recorded value; if the neutral 
density filter is 1.0, then add 10dB to the non-zero recorded value; if the neutral density filter is 
2.0, then add 20dB to the non-zero recorded value.

Subgroup Analyses 
Subgroup analysis will be performed based on baseline GA values for the primary endpoint.  The 
subgroup cutoff value will be chosen based on the the median of baseline GA size to analyze the 
data properly. 
5.1.1.6 
Interim Analyses 
One interim analysis was conducted when 100% of patients complete the Month-12 visit and 50% 
of patients complete the Month-18 visit. The study was terminated based on results from the 
interim analysis. 
5.1.2 
Determination of Sample Size 
Sample size determination was based on previous data or literature (Holz et al, 2010).  The 
following assumptions were made:  A GA lesion size of 2.8 mm2 for the Sham and 2.1 mm2 for 
the Brimo DDS groups (a 25% reduction from the Sham treatment) and a common SD of 1.65 
mm2. Under these assumptions, 120 patients will be required in each treatment group to detect 
the above treatment difference with a power of 90% or greater at the 2-sided t-test with 5%

significance level. With an anticipated dropout rate of 20%, approximately 300 patients will be 
enrolled such that 240 (120 per group) will complete the Month 24 visit. The sample size 
calculations are based on the procedure MTTO-1 in nQuery (v6.01). 
The sample size assumptions and estimate are summarized as follows:

Changes in the Conduct of the Study 
Prior to database lock, there were no changes in study conduct from what was described in the 
protocol. 
5.2.2 
Changes to Analyses Prior to Database Lock 
According to the study protocol (section 7.1), mITT and safety populations would be analyzed 
based on the actual treatment that the patient received (as treated). However, the analysis based 
on mITT population will be conducted based on the treatment to which the patient was 
randomized (as randomized), and the analysis based on safety population will be based on the 
actural treatment received. The deviated patients between randomized and actual treatment 
received will be listed. In addition, analysis based on per-protocol population (PP) will not be 
performed.  
 
Presence or absence of reticular drusen measured by near-IR (NiR), instead of area of reticular 
drusen assessed using NiR images, will be analyzed due to the technical difficulties to measure 
reticular drusen. GA lesion area by FAF in fellow eye was not obtained and will not be analyzed. 
Medical and ophthalmic history, the atrophic lesion area assessed with SD-OCT examination, 
and the location of implants and fragments will be not analyzed due to the changed scope of the 
analyses.

randomization, then the patient will be analyzed using the intended stratum in which the patient 
should have been randomized.

SUMMARY OF CHANGES 
 
The following planned lesion area by SD-OCT analyses will be conducted post-hoc after the DBL:  
1. Table 14.2-1.7 “Geographic Atrophy Lesion Area (mm2) by SD-OCT: Raw and Change from 
Baseline”  
2. Table 14.2-1.8 “Geographic Atrophy Lesion Area (mm2) by SD-OCT: Raw and Change from 
Baseline; Lesion Area < 4.5 mm2”  
3.  Table 14.2-1.9 “Geographic Atrophy Lesion Area (mm2) by SD-OCT: Raw and Change 
from Baseline; Lesion Area >= 4.5 mm2”  
Continuous 
descriptives 
• 
N1, mean, standard deviation (SD), median, minimum, maximum 
• 
N1 = number of participants with non-missing value 
CFB MMRM 
• 
Continuous descriptives for baseline, postbaseline, and CFB values 
• 
Estimates derived from mixed model for CFB value controlling for factors 
(treatment group, study region, analysis visit), covariate (baseline GA lesion 
size as measured by SD-OCT) and interaction (treatment group by analysis 
visit, treatment group by baseline value).  
o Least squares (LS) means, standard errors, and 95% confidence 
intervals for within group change from baseline 
o LS mean differences, standard errors, and confidence intervals vs 
Placebo 
o P-values from contrast t-test comparing treatment group vs. Placebo 
o N1 = participants with non-missing values at both baseline and the 
specified postbaseline analysis visit
