Key Exclusion Criteria:   
 
  
 
 
 
 
 
 
 
 
 
 
 
• laser photocoagulation to the retina of the study eye within 3 months prior to screening   
 
 
   
 
 
 
 
 
 
 
 
 
 
Response Measures 
Efficacy:  BCVA measured by ETDRS, central retinal thickness measured by OCT, area of macular leakage 
measured with fluorescein angiography (FA) 
 
 
  
  
 
General Statistical Methods and Types of Analyses:   
Analysis Populations:  Three populations will be used for statistical analyses:  modified intent-to-treat (mITT),  
per-protocol (PP), and safety. 
Primary Efficacy Analysis:  The primary efficacy endpoint is the average change from baseline in BCVA over 
12 months.  The primary analysis will be an analysis of covariance (ANCOVA) comparing the treatment 
difference in the mean average BCVA change from baseline in a 12-month study period.  The ANCOVA model 
will include the treatment group as the main effect and baseline BCVA score as the covariate.  The average 
change will be computed by subtracting the baseline BCVA from the area under the BCVA curve (AUC) 
divided by the total follow-up time for each patient.  Calculations for AUC will be based on observed data using

the trapezoidal method and will include all postbaseline BCVA data for the patient from the study treatment to 
the last VA measurement, regardless of scheduled or unscheduled visits.   
Secondary Efficacy Analyses:  Secondary efficacy analyses include a Cochran–Mantel-Haenszel (CMH) test 
stratified within each study site by baseline BCVA categories (≥ 34 to ≤ 49 and  ≥ 50 to ≤ 70) for treatment 
difference in proportion of patients with ≥ 15 letters improvement from baseline of BCVA at month 12; and 
ANCOVA on retinal thickness and total leakage area at month 12.

1. 
 Background and Clinical Rationale  
Diabetes affects more than 220 million people worldwide (World Health Organization, 
WHO Diabetes Fact Sheet, 2011) and its prevalence is expected to grow to 366 million by 
2030 (Wild et al, 2004).  Diabetic macular edema (DME) is 1 of the major causes of vision 
loss in patients with diabetic retinopathy (Resnikoff et al, 2004).  Diabetic retinopathy (DR) 
and DME are common microvascular complications in patients with diabetes and may have 
sudden and debilitating impact on VA, eventually leading to blindness.  DME is a frequent 
manifestation of DR and is a major cause of vision loss in patients with DR.  DME results 
from retinal microvascular changes.  Thickening of the basement membrane and reduction in 
the number of pericytes are believed to lead to increased permeability and incompetence of 
the retinal vasculature.  This compromise of the blood-retinal barrier (BRB) leads to the 
leakage of plasma constituents into the surrounding retina, with subsequent retinal edema 
(Albert and Jakobiec, 2000).  Increase of vascular permeability and breakdown of the BRB in 
DME is thought to be caused by vascular epithelial growth factor (VEGF) effects, such as 
phosphorylation of tight junctional protein occludin and Fas-mediated endothelial cell 
apoptosis, and also by inflammatory effects like leukostasis, possibly due to increased 
expression of leukocyte adhesion molecules (Aiello et al, 1997). 
Laser photocoagulation has been shown to be efficacious in the prevention of mild to 
moderate vision loss from DME (ETDRS Report #1, 1985).  In the ETDRS protocol, laser 
photocoagulation reduced the risk of moderate visual loss from DME by 50% (from 24% to 
12% 3 years after initiation of treatment (ETDRS Report #2, 1987).  However, few patients 
experience improvement in vision following laser alone for DME, and persistent and 
recurrent macular edema is common (ETDRS Report #9, 1991).  DME due to DR may come 
from discrete points of leakage (focal edema) or from geographic areas of diffuse retinal 
vascular hyperpermeability (diffuse edema).  Diffuse diabetic macular edema is particularly 
refractory to laser treatment  (Bresnick, 1983).  The present study will use a modified 
EDTRS protocol (Modified-ETDRS Focal Photocoagulation Technique [Internet], 2006) 
commonly used in clinical practice (See Section 12.1.11). 
Ranibizumab has been approved for the treatment of DME in Europe and more recently 
(August 2012) in the USA. However, in China, for example, ranibizumab is approved only 
for treatment of age-related macular degeneration (AMD) and laser photocoagulation 
remains the current standard of care for DME.

Corticosteroids modulate vascular permeability through anti-inflammatory effects, in 
addition to suppressing production of VEGF and other permeability factors.   
Dexamethasone, a potent corticosteroid, has been shown to suppress inflammation by 
inhibiting edema, fibrin deposition, capillary leakage, and phagocytic migration of the 
inflammatory response.  In the past, the use of dexamethasone has yielded limited success in 
treating retinal disorders including macular edema, largely due to the inability to deliver and 
maintain adequate quantities of the drug to the posterior segment (Ahmed and Ai, 1999).  The 
dexamethasone Posterior Segment Drug Delivery System (DEX PS DDS) delivers a 700 µg 
total dose of dexamethasone to the vitreous with gradual release over time (Investigators 
Brochure) allowing for sustained drug levels to the target areas.  DEX PS DDS is composed 
of dexamethasone homogeneously dispersed into a biodegradable matrix composed of 
copolymers of lactic acid and glycolic acid, PLGA
 (poly [lactic-glycolic] acid), a material 
commonly used in medical devices such as absorbable sutures (Moritera et al, 1991; Singhal 
et al, 1988; Vicryl
® package insert, 1997; Visscher et al, 1985).  The DEX PS DDS does not 
need to be removed since the copolymer dissolves and absorbs over time.  An applicator (see 
Figure 2) was designed to facilitate intravitreal placement of the extruded DEX PS DDS.  By 
effectively delivering dexamethasone into the vitreous, DEX PS DDS offers a valuable new 
therapeutic option in the treatment of macular edema.

One of the most frequently reported adverse events associated with ophthalmic corticosteroid 
use is elevated intraocular pressure (IOP).  Although elevations of IOP were significantly 
more prevalent with DEX PS DDS than with sham, the increases either did not require 
treatment or were managed with topical IOP-lowering medications.  Like all injectable 
steroids, there was a higher incidence of cataracts with DEX PS DDS (7.4%) compared to 
sham (4.5%).  However, only 2 cataract surgeries were performed in the study eye (SE) 
during the 6-month study period. 
In the pivotal studies for patients with macular edema secondary to RVO, 98% of patients 
received a second injection of DEX PS DDS between 5 and 7 months after the initial 
treatment.  Post hoc analysis of these previous studies suggest that patients dosed between 
months 5 and 6 have better outcomes than the overall study population. 
Allergan has completed 1 phase 2 study with 700 µg DEX PS DDS in patients with DME.  
Study 206207-012 (PLACID study) was a 52-week, masked, multicenter, randomized, 
controlled trial (with up to 13 weeks additional follow up) to assess the safety and efficacy of 
700 µg DEX PS DDS in combination with laser photocoagulation in the treatment of patients 
with diffuse DME.  A
 total of 253 patients were randomized and enrolled in the study:   
126 in the Combination Therapy group and 127 in the Laser Alone group.  Intravitreal 
injection with 700 µg DEX PS DDS in combination with laser treatment was shown to 
provide more prolonged reduction in macular thickening and better VA
 overall than laser 
alone in patients with diffuse DME.  Treatment with combination therapy led to better 
outcomes than laser alone in improving vision at month 1 (31.7% versus 11.0%; p < 0.001) 
and at month 4 (26.2% versus 16.5%; p = 0.060) in the ITT population.  There was no 
statistically significant difference between the treatment groups at month 6. 
The aim of this study is to demonstrate that DEX PS DDS administered every 5 months will 
lead to greater improvement of VA
 than laser photocoagulation over 1 year of treatment.

2.2 
 Clinical
  Hypotheses
 
• Treatment with 700 µg DEX PS DDS every 5 months is superior to laser 
photocoagulation according to the modified ETDRS protocol (with respect to the average 
change from baseline of BCVA
 during 12 months of treatment for DME) 
• 700 µg DEX PS DDS administered every 5 months has an acceptable safety profile 
3. 
 Study
  Design
 
This study is a multicenter, randomized, 12-month comparative study to evaluate if 700 µg 
DEX PS DDS administered every 5 months is safe and can achieve improvement of BCVA
  
superior to laser photocoagulation administered according to the modified ETDRS protocol 
(Section 12.1.11). 
Consenting patients will participate in a screening period lasting 2 to 14 days to evaluate 
patient eligibility
.  After eligibility has been determined by the investigator, patients will be 
randomized in a 1:1 ratio to receive: 
• 700 µg DEX PS DDS every 5 months  
or 
• laser photocoagulation according to the modified ETDRS protocol  
The randomization will be stratified by BCVA
 score at baseline (≥ 34 to ≤ 49 and 
 ≥ 50 to ≤ 70) within each investigator site.  The primary efficacy measure is average change 
of BCVA
 over a period of 12 months.  The total duration of study participation for each 
patient is approximately 12.5 months including screening and randomization/retreatment 
period.  Patients will attend the following 11 visits:  screening visit, randomization visit, 
8 assessment/retreatment visits, and study exit visit. 
4. 
 Study Population and Entry Criteria 
4.1 
 Number of Patients  
Approximately 356 patients will be enrolled at approximately 20 sites to ensure that at least 
151 patients in each treatment group complete the study
.  Of those, approximate10 patients 
assigned to DEX PS DDS at selected sites will participate in therapeutic drug monitoring.

necessary
. 
Cataract surgery:  If a patient develops visually significant cataracts during the study period, 
the decision to perform cataract surgery is left to the discretion of the investigator and the 
patient.  Cataract surgery should be considered under the following conditions: 
• visual function no longer meets the patient’s needs and cataract surgery provides a 
reasonable likelihood of improvement 
• lens opacity inhibits optimal management of posterior segment disease 
• the lens causes inflammation (phacolysis, phacoanaphylaxis), angle closure, or medically 
unmanageable open-angle glaucoma 
Topical steroids, periocular, or intravitreal steroid injections:  allowed to treat inflammatory 
conditions in nonstudy eye 
Intravitreal anti-VEGF treatment:  allowed in the nonstudy eye

Use of systemic nonsteroidal anti-inflammatory drugs (NSAIDs):  systemic NSAIDs 
regularly used prior to enrollment will be allowed to continue during the study
, and should be 
administered at a dosage that remains constant throughtout the course of the trial. 
Nonocular steroids:  low-dose creams and ointments; intraarticular, inhaled, intranasal and 
ear drops allowed 
Panretinal photocoagulation:  if needed to treat neovascularization 
For patients who are assigned to DEX PS DDS drug monitoring, no corticosteroids (except 
the study medication) are allowed during the first 6 months. 
4.5.2 
 Acceptable Contraceptive Methods 
Women of childbearing potential must use reliable contraception.  The investigator and each 
patient will determine the appropriate method of contraception for the patient during the 
participation in the study
. 
If a female of childbearing potential 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 (if 
applicable), 700 µg DEX PS DDS, and (2) follow the progress of the pregnancy
.  The 
investigator should discontinue study treatment, 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. 
The following medications should be avoided during the study: 
• SE-intravitreal injections of any sort other than the study medication 
• SE-sub-tenon, subconjunctival or topical corticosteroids

5. 
 Study
  Treatments
 
 
5.1 
 Study Treatments and Formulations 
The study treatment will be dexamethasone intravitreal implant containing 700 µg 
dexamethasone in a solid polymer delivery system. 
5.2 
 Control
  Treatment
 
 
The control treatment will be laser photocoagulation according to modified ETDRS protocol. 
 
5.3 
 Escape
  Therapy
 
Treatment according to standard of care (SOC) should be considered for patients with a 
decrease of BCVA
  > 10 ETDRS letters from baseline, which is confirmed at 2 consecutive 
visits.  Patients who receive escape therapy will no longer eligible to receive study treatment, 
but will continue in the study for safety assessments.   
5.4 
 Methods for Masking/Blinding 
Study personnel collecting primary efficacy (BCVA) data and evaluators at the reading center 
will be blinded to study treatment assignment for the duration of the trial.  The BCVA
 
technician may not assist nor be present during the treatment procedure, as they need to 
remain unaware of patient treatment assignments.

5.5 
 Treatment Allocation Ratio and Stratification  
Patients will be randomized in a 1:1 ratio to either 700 µg DEX PS DDS or laser 
photocoagulation. 
The randomization will be stratified by BCVA
 score at baseline (≥ 34 to ≤ 49 and ≥ 50 to 
≤ 70) within each study site. 
5.6 
Method for Assignment to Treatment Groups/Randomization 
Prior to initiation of study treatment, each patient who provides informed consent and/or 
assent will be assigned a patient number that will serve as the patient identification number 
on all study documents. 
An automated interactive voice response system (IVRS) or interactive web response system 
(IWRS) will be used to manage the randomization and treatment assignment based on a 
randomization scheme prepared by Allergan Biostatistics. 
Study medication will be labeled with medication kit numbers.  The IVRS/IWRS system will 
provide the site with the specific medication kit number(s) for each randomized subject at the 
time of randomization.  Sites will dispense study medication/treatment according to the 
IVRS/IWRS instructions.  Sites will also call the IVRS or log onto the IWRS at subsequent 
visits to obtain a study medication kit number for dispensing study medication.  Sites will 
receive the IVRS/IWRS confirmation notifications for each transaction.  All notifications are 
to be maintained with the study source documents. 
5.7 
 Treatment Regimen and Dosing 
5.7.1 
 DEX PS DDS  
Patients assigned to the DEX PS DDS treatment group will receive 700 µg dexamethasone in 
a solid polymer delivery system at day 1, months 5, and 10.

5.9 
 Study Drug Administration  
5.9.1 
 Peri-operative
 Anti-infective
  Treatment
 
At the visit preceding each study drug administration, the patient will be given antibiotic 
ophthalmic solution (as applicable according to local practice) and instructed to instill a drop 
in the SE 4 times per day (QID) for 3 days prior to the study treatment procedure and up to 
QID (depending on the time of the study treatment procedure) on the day of the procedure, 
and QID for 3 days postoperatively
.  Patients should be instructed not to wear contact lenses 
while using antibiotics.  See the Procedure Manual for further details. 
5.9.2 
 Product
  Dispensing
 
 
Only qualified patients will receive study treatment.  The assigned staff member will access 
the IVRS/IWRS after patient randomization has been completed approximately 30 minutes 

Allergan Confidential 
Protocol 206207-026 Amendment 1 
700 µg DEX PS DDS 
 
 
 
26 
 
 
prior to the study treatment procedure to receive study treatment kit numbers that can be used 
for each patient (see the Procedure Manual for the IVRS/IWRS details).  Upon initial access 
to the IVRS/IWRS, a study treatment kit will be dispensed.  In the unlikely event that the 
initial applicator fails, the assigned staff member will access the IVRS/IWRS again to receive 
a second study treatment kit number to use.  Although it is not expected that further kits will 
be required, should further study treatment kits fail, up to a fourth kit may be obtained by 
accessing the IVRS/IWRS again.  If the fourth study treatment kit fails, the study treatment 
procedure should be aborted, and Allergan should be notified immediately
. 
The DEX PS DDS must only be handled at the time of the procedure and only under sterile 
conditions.  The study medication must be placed in enrolled patients’
 eyes by an investigator 
who possesses acceptable experience as determined by Allergan. 
5.9.3 
 Final Product Disposition 
The used applicators will be destroyed by the site.  For unused malfunctioning applicators, 
the assigned site personnel will record the nature of the malfunction on the appropriate form.  
The malfunctioning applicators will be destroyed by the site.  All unused applicators will be 
returned for destruction according to Allergan instructions. 
5.9.4 
 Operative
  Procedure
 
The study treatment procedure must be performed only in an operating room, surgical suite, 
or in an office setting using a sterile technique, as described in the Procedure Manual.  The 
study treatment kit(s) should be readily available during the procedure. 
Prior to study treatment, the SE of each patient will be anesthetized with topical and/or 
subconjunctival anesthetic and prepared according to the investigator’s standard of practice.  
Patients randomized to active treatment will have the study drug placed into the vitreous 
through the pars plana using the DEX PS DDS.  See the Procedure Manual for further details. 
Once the DEX PS DDS is deployed, the lever becomes locked to indicate that the applicator 
has been used and prevents reuse.

 Examination
  Procedures,
  Tests,
 Equipment, and Techniques  
6.4.1 
 Best-corrected
  Visual
 Acuity
 
BCVA
 in the SE and in the nonstudy eye will be measured using the ETDRS VA
 protocol 
following manifest refraction.  All BCVA
 data will be used to assess safety as well as 
efficacy
. 
6.4.2 
 Optical
  Coherence
  Tomography
 
OCT is a laser-based, noninvasive, diagnostic system providing high-resolution imaging 
optical sections of the retina.  The mean retinal thickness in the 1-mm central subfield of the 
SE will be captured using time-domain OCT (Stratus III, Zeiss) or spectral-domain OCT 
(Cirrus, Zeiss or Spectralis, Heidelberg).  Electronic OCT images will be collected for 
evaluation by a reading center
.  Once an OCT instrument has been selected for a patient, that 
instrument must be used for all the study assessments for that patient for the duration of the 
study
. 
6.4.3 
 Fluorescein
 Angiography
 
Early and transit images will be taken of the SE.  Mid- and late-phase images will be taken of 
the study and nonstudy eye.  Electronic FA
 images will be collected for evaluation by a 
reading center
. 
6.4.4 
 Intraocular Pressure Measurement 
IOP will be measured using a Goldmann applanation tonometer instrument or a hand held 
tonometer
.  Once an instrument for IOP measurement has been selected for a patient, that 
instrument must be used for all the study assessments for that patient for the duration of the 
study
. 
6.5 
 Other Study Supplies 
Laboratory kits for the collection and shipment of hematology
, biochemistry
, and urine 
samples, including pregnancy test kits, will be provided by the central laboratory contracted 
by Allergan.

6.6 
 Summary of Methods of Data Collection 
An IVRS/IWRS will be used to screen, randomize, and manage study medication inventory
. 
Data will be collected using electronic case report form (eCRF) via a validated electronic 
data capture (EDC) system.  Source documents will be used and stored at sites, and may 
include a patient’s medical records, hospital charts, clinical charts, patient chart, copy of the 
EDC file, as well as the results of diagnostic tests, such as laboratory tests and ophthalmic 
examinations or tests.  A
 central lab will be used for the analysis of all blood samples.  A
 
central reading facility will be used for FA
 and OCT evaluations.  
7. 
 Statistical
  Procedures
 
One database lock will occur when all patients have either completed the study or 
discontinued from the study prematurely
.  The study will be unmasked for statistical analysis 
following the database lock.  A
 detailed analysis plan will be approved prior to database lock. 
7.1 
 Analysis
  Populations
 
Three analysis populations will be used for statistical analyses:  modified intent-to-treat 
(mITT), per-protocol (PP), and safety
. 
The mITT population will include all randomized and treated patients with at least 1 
postbaseline BCVA
 measurement.  The mITT population will be used for analysis of efficacy 
variables and baseline characteristics based on the randomized treatment group.   
The PP population will include all randomized and treated patients without any significant 
protocol violations.  The PP population will be used to analyze the primary efficacy variable 
as a secondary efficacy analysis.  The PP analysis will be based on the actual treatment that 
the patients received.   
The safety population will include all treated patients.  This population will be used for the 
safety analysis that will be based on the actual treatment that the patients received. 
7.2 
 Collection and Derivation of Primary and Secondary  Efficacy 
Assessments 
BCVA
 measured in the SE using the ETDRS method will be the primary efficacy assessment.  
For each patient, BCVA
 data will be collected for both the study and nonstudy eyes at the 

Allergan Confidential 
Protocol 206207-026 Amendment 1 
700 µg DEX PS DDS 
 
 
 
30 
 
 
screening, day 1/randomization day (prior to the study treatment), and months 1, 2, 3, 5, 6, 7, 
9, 10, and 12/exit (or early exit) visits.  Analysis of BCVA
 obtained from the SE will be 
performed for efficacy
.  BCVA
 data from the nonstudy eye will be used only for safety 
evaluations. 
VA
 will be recorded on the CRF as the number of letters correctly read.  For a given eye, the 
4-meter distance (standard) of VA
 will be tested first.  If the patient correctly reads at least 
20 letters at 4 meters, the VA
 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 VA
 will be 
measured again at 1 meter
.  The VA
 score will be set to the number of letters read correctly at 
1 meter plus the number of letters read correctly at 4 meters. 
BCVA
 measured at the randomization visit on day 1 prior to the study treatment will be 
considered as baseline for change from baseline.  BCVA
 data measured at the screening visit 
will be used for baseline only in the absence of BCVA
 data at the randomization visit on 
day 1.   
7.2.1 
 Primary
  Efficacy
  Variables
 
 
The primary efficacy variable is the average change from baseline in BCVA
 over the 
12-month study period.  The average change will be computed by subtracting the baseline 
BCVA
 from the area under the BCVA
 curve (AUC) divided by the total follow-up time for 
each patient.  Calculations for AUC will be based on observed data using the trapezoidal 
method and will include all postbaseline BCVA
 data for the patient from the study treatment 
to the last VA measurement, regardless of scheduled or unscheduled visits.   
7.2.2 
 Secondary
  Efficacy
  Variables
 
Secondary efficacy variables include:   ≥ 15 letters improvement from baseline in BCVA
 at 
month 12; change from baseline in the retinal thickness based on OCT at month 12; and 
change from baseline in total leakage area based on FA
 at month 12. 
Change From Baseline in Retinal Thickness Based on OCT 
OCT is a laser-based diagnostic system providing high-resolution optical sections of the 
retina.  OCT will be performed at the investigators’
 sites.  The OCT images will be 
transferred to the reading center and evaluated by the retina specialists of the reading center 

Allergan Confidential 
Protocol 206207-026 Amendment 1 
700 µg DEX PS DDS 
 
 
 
31 
 
 
for the SE.  The retinal thickness (microns) in the central 1-mm macular subfield based on 
OCT will be assessed and analyzed as the secondary efficacy variable. 
Change From Baseline in Total Leakage Area Based on FA 
FA
 is a technique to examine the circulation of the retina using the dye tracing method.  It 
involves injection of sodium fluorescein into the systemic circulation, and then an angiogram 
is obtained by photographing the fluorescence emitted after illumination of the retina.  The 
focal and diffuse leakage area based on FA
 will be assessed.  The total leakage area defined 
as the sum of focal and diffuse leakage area will be computed and analyzed as the secondary 
efficacy variable. 
7.3 
 Hypothesis and Methods of Analysis 
Unless stated otherwise, analyses for efficacy will be performed using the mITT population 
based on the 2-sided hypothesis test with a nominal significance level of 0.05. 
7.3.1 
 Primary
  Efficacy
 Analyses
 
The primary efficacy endpoint is the average change from baseline in BCVA
 in 12 months.  
The primary analysis will be an analysis of covariance (ANCOVA) comparing the treatment 
difference in the mean average BCVA
 change from baseline over a 12-month study period.  
The ANCOVA
 model will include the treatment group as the main effect and baseline BCVA
 
score as the covariate.  
The null hypothesis is that there is no difference between 700-µg DEX PS DDS and laser in 
the average BCVA
 change from baseline in a 12-month period.  The alternative hypothesis is 
that there exists a difference between the 2 treatment groups.  The hypothesis test will be 
based on a 2-sided test at 0.05 significance level.  In addition, a 2-sided 95% confidence 
interval (CI) will be constructed for the difference between the treatment groups in 
least-square means using the same ANCOVA
 model.  Data collected after receiving any 
prohibited or standard of care treatments will be excluded from all the efficacy analysis. 
7.3.2 
 Secondary
  Efficacy
 Analyses
 
Analysis for proportion of patients with 15 or more letters improvement from baseline in 
BCVA
 at month 12 will be done using a Cochran–Mantel-Haenszel (CMH) test stratified by 
baseline BCVA
 categories (≥ 34 to ≤ 49 and ≥ 50 to ≤ 70) within each study site.   

Allergan Confidential 
Protocol 206207-026 Amendment 1 
700 µg DEX PS DDS

Analysis for change from baseline in retinal thickness at month 12 will be performed using 
an ANCOVA
 model with treatment and baseline BCVA
 score (≥ 34 to ≤ 49 and  ≥ 50 to ≤ 70) 
as the main effects and baseline retinal thickness as the covariate.  The between-group 
difference and the corresponding 2-sided 95% CI in least-square means will be computed 
using the ANCOVA
 model.  The within-group change from baseline will be analyzed using 
the paired t-test at the follow-up visits. 
Analysis for change from baseline in total leakage area at month 12 will be performed using 
an ANCOVA
 model with treatment and baseline BCVA
 score (≥ 34 to ≤ 49 and ≥ 50 to ≤ 70) 
as the main effects and baseline total leakage area as the covariate.  The between-group 
difference and the corresponding 2-sided 95% CI in least-square means will be computed 
using the ANCOVA
 model.  The within-group change from baseline will be analyzed using 
the paired t-test at the follow-up visits. 
 
 
 
 
 
 
 
  
 
7.3.4 
 Safety
 Analyses
 
The Medical Dictionary for Regulatory Activities (MedDRA) nomenclature will be used to 
code adverse events and biomicroscopy data.  
The number and percent of patients reporting adverse events will be tabulated by primary 
system organ class, preferred term, and severity for adverse event summarization.  The 
summary tables will be generated separately for adverse events reported during the screening 
to baseline period (pre-adverse event) and treatment emergent period.  Summaries for 
treatment-emergent adverse events will be organized into the following:  all adverse events 
regardless of causality; treatment-related adverse events; ocular adverse events in the SE; and 
treatment-related ocular adverse events in the SE.

  Event
 
An adverse event is defined as 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.

Adverse events will be assessed and documented, as appropriate, 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, nondirected 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 eCRF
.   
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 and may require 
medical or surgical intervention to prevent 1 of the outcomes listed in this definition.  (See 
Section 9.3 for procedures for reporting a serious adverse event.) 
Note:  Allergan considers all cancer adverse events as serious adverse events.  In addition, 
Allergan considers any abortion (spontaneous or nonspontaneous) as a serious adverse event. 
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 should 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 that 
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 

Allergan Confidential 
Protocol 206207-026 Amendment 1 
700 µg DEX PS DDS 
 
 
 
43 
 
 
determination is made that there is a reasonable possibility that the adverse event may have 
been caused by the drug or study procedure.   
9.2 
 Procedures for Reporting Adverse Events 
Any adverse event should be recorded on the appropriate eCRF
. 
All adverse events that are drug-related and unexpected (not listed as treatment-related in the 
current Investigators Brochure) are to 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. 
9.3 
 Procedures for Reporting a Serious Adverse Event 
Any serious adverse event occurring during the study period (beginning with informed 
consent) and for at least 2 months after the last dose of study drug should be immediately 
reported to an Allergan representative listed on the Allergan personnel page and recorded on 
the appropriate eCRFs.  All patients with a serious adverse event must be followed up, and 
the outcomes reported.  The investigator should supply Allergan and the IRB/IEC with any 
additional requested information (eg, autopsy reports and terminal medical reports).  
In the event of a serious adverse event, the investigator must: 
1. Notify Allergan immediately by fax using the serious adverse event reporting forms 
(for serious adverse event fax number, see page 1 of the protocol).  Emergency 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 case history (adverse event report form) that 
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.

Iris Color (screening only) 
Iris color will be recorded at screening using the following classification:  blue, green, hazel, 
brown, or other (specify).  
12.1.7.6 Lens 
Lens Status 
Lens status will be assessed as phakic, pseudophakic, or aphakic. 
Cataract Assessment (phakic eyes only) 
Presence and severity of nuclear, cortical, and posterior subcapsular cataract lens opacities 
will be evaluated by comparing biomicroscopic findings with standard photographs (refer to 
the Procedure Manual for further details).  Grades are assigned as follows for each type of 
opacity: 
Opacity is absent 
Opacity is present, but less than standard photo #2 
Opacity is present and as severe as or worse than standard photo #2

12.1.11 
Modified-ETDRS Focal Photocoagulation Technique 
The laser treatment “session” should generally be completed in a single “sitting.”  The 
photocoagulation treatment technique, as described below
, is a modification of the ETDRS 
technique and is the treatment approach that is commonly used in clinical practice 
(Modified ETDRS Focal Photocoagulation Technique [Internet], 2006).

Direct/grid photocoagulation (modified-ETDRS technique) 
Direct treatment 
Directly treat all leaking microaneurysms (MA) in areas of 
retinal thickening between 500 and 3000 microns from the 
center of the macula (although may treat between 300 and 
500 microns of macula if center-involved edema persists 
after initial focal photocoagulation, but generally not if the 
visual acuity is better than 20/40)
