Name of Investigational Product:  DE-122 injectable solution 
Name of Active Ingredient:  DE-122, a chimeric anti-CD105 (Endoglin) IgG1 antibody consisting of 
human Cκ and Cγ1 constant regions with murine Vκ and VH regions 
Title of Study:  A Multi-Center, Randomized, Double Masked and Active Controlled Phase II Study 
Assessing the Efficacy, Safety of Intravitreal Injections of DE-122 in combination with Lucentis® 
Compared to Lucentis® Monotherapy in Subjects with Wet Age-related Macular Degeneration 
- AVANTE study 
Study Period:  Approximately 31 months 
Estimated date first subject enrolled: July 2017 
Estimated date last subject completed: January 2020 
Phase of Development:  
Phase II 
Primary Objective:  
 
To assess the safety and efficacy of repeated intravitreal injections of DE-122 (2.0 mg/eye and  
4.0 mg/eye) given in combination with Lucentis® in subjects with wet age-related macular 
degeneration (AMD) compared with Lucentis® alone. 
Secondary Objective:  
 
To evaluate the pharmacokinetics and immunogenicity of DE-122 following repeated IVT 
injections of DE-122 in subjects with wet AMD in serum samples.  
 
To evaluate biomarker candidates of DE-122 following repeated IVT injections of DE-122 in 
subjects with wet AMD in both serum and aqueous humor samples. 
Methodology: 
This is a randomized, double masked and active controlled study assessing the safety and efficacy of 
repeated intravitreal injections of DE-122 (2.0 mg or 4.0 mg) in combination with Lucentis® compared 
to Lucentis® monotherapy in subjects with wet AMD.  Approximately seventy six (76) subjects with 
wet AMD will be randomly assigned to one of three treatment arms:  
Arm 1: Sham + Lucentis® 0.5 mg (N=17) 
Arm 2: DE-122, 2.0 mg + Lucentis® 0.5 mg (N=31) 
Arm 3: DE-122, 4.0 mg + Lucentis® 0.5 mg (N=28) 
Subjects will receive 6 monthly intravitreal injections of DE-122 (2.0 mg or 4.0 mg) or Sham, in 
combination with Lucentis®.  The primary analysis will be performed when all subjects complete the 
Week 24 visit.  
The first 6 subjects will be randomized to Arm 1 or Arm 2 in a 1:1 ratio in Stage 1.  The Safety Review 
Team will review the safety parameters of the 6 subjects in Stage 1 and determine if the safety and 
tolerability at Week 4 are acceptable.  If so, enrollment will be continued in a 1:2:2 ratio in the three 
arms for the remaining approximately 70 subjects in Stage 2.  
To be eligible, subjects must have a diagnosis of active CNV secondary to AMD, with some subfoveal 
component (CNV, fluid, or hemorrhage under the fovea) with lesions ≤ 12 disc areas and ≤ 50% 
hemorrhage in the study eye. Subjects must be previously treated (i.e., At least 3 IVT injections of  
Anti-VEGF for treatment naïve eyes or eyes adequately maintained on continuous intravitreal anti-

VEGF therapy).  Subjects with Polypoidal Choroidal Vasculopathy (PCV) lesions will be allowed, but 
Retinal Angiomatous Proliferation (RAP) lesions will be excluded from this study.  Screening Visit 
SD-OCT images and Fluorescein Angiography from Investigator-identified eligible subjects will be 
sent to the central reading center to confirm eligibility based on AMD lesion attributes specified in the 
protocol.  To balance the randomization, subjects will be stratified by subgroups on the reading center’s 
assessment of lesion type, up to approximately one third (1/3) of the subjects in each arm should have 
PCV in Stage 2.  Subjects must satisfy all other inclusion and exclusion criteria. 
Subjects must have best corrected visual acuity (BCVA) of 65 to 25 ETDRS letters (equivalent to 20/50 
to 20/320 Snellen) in the study eye. 
Eligible subjects who are enrolled in the study will be seen for up to 14 visits.  
Subjects are eligible for rescue with any anti-VEGF IVT during the Week 24 and Week 28 if one of the 
following rescue criteria is met:  
Rescue Criteria: 
 BCVA decrease of ≥ 5 letters from the last visit  
 Central subfield thickness (CST) increase of ≥ 50 µm from the last visit  
 The discretion of investigator 
Number of Subjects (planned): 
Approximately 76 subjects with wet AMD will be enrolled at approximately 14 sites. 
Duration of the Study: 
The total study period for each subject will include a screening period (up to 14-days), then a treatment 
and follow up period (up to 32 weeks). 
Masking: 
This is a double-masked study, with subjects and examiners including the Principal Investigator (PI) 
masked to the treatment regimen.  However, the designated injecting physician (not the PI) will not be 
masked to the treatment regimen. 
The Sponsor will have masked and unmasked data review teams. The designated Safety Review Team 
will review the safety data of the 6 subjects in Stage 1 to determine if the safety and tolerability of the 
doses at Week 4 are acceptable. 
Diagnosis and Main Criteria for Inclusion:

as determined by a central reading center 
 
Change from baseline in greatest linear dimension of the total lesion area by FA, as determined 
by a central reading center 
A Follow-up Analysis is planned when all subjects complete the Week 32 visit.  The Analysis will 
include the number of anti-VEGF injections used for Rescue in addition to efficacy and safety data. 
Safety:  
The safety assessments will include adverse events (AEs), slit lamp biomicroscopy, indirect 
ophthalmoscopy, BCVA, IOP, fundus photography, fluorescein angiography, serum chemistry, 
hematology, urinalysis, vital signs, physical examination, EKG, and pregnancy. 
Immunogenicity:  
ADA titer will be measured in all subjects at prior to the Lucentis® injection of Day 1, and at Week 24. 
Pharmacokinetics (PK): 
Levels of DE-122 in serum will be determined and pharmacokinetic assessments will be performed on 
a subset of subjects.  
Pharmacogenomics/genomics: 
Subjects who have consented will provide a blood sample for a future Pharmacogenomics/genomics 
laboratory research.  The purpose of this Pharmacogenomics/genomics analysis is future exploratory 
research to identify possible genetic markers, associated with the study drug(s) and/or ophthalmologic 
disease conditions.  Blood sample will be collected once at Day 1 or any visit after Day 1 during the 
study. 
Biomarker Candidates: 
The exploratory investigation of biomarker candidates will be examined in serum and aqueous humor 
in subjects who give their consent. The samples will also be stored for future exploratory research to 
identify possible biomarkers associated with the study drug(s) and/or ophthalmologic disease 
conditions.  Serum samples and aqueous humor samples (optional) will be collected on certain 
scheduled visits.  SS-OCT angiography images will be taken at selected sites and stored. 
Statistical Methods: 
The primary analysis will be performed at Week 24. All safety and efficacy data will be summarized by 
treatment arms with descriptive statistics. BCVA and CST data will also be presented graphically. 
Due to the exploratory nature of this study, the sample size was not calculated for a statistical power.

INTRODUCTION 
AMD is the leading cause of irreversible vision loss in developed countries.  AMD is 
characterized by extracellular matrix deposits, known as drusen, accumulating between the 
retinal pigment epithelium and Bruch’s membrane.  In exudative or wet AMD unwanted blood 
vessels grow into the macula which leads to hemorrhage and subretinal fluid.  In addition, retinal 
pigment epithelial detachment, retinal tears, fibrovascular scarring and vitreous hemorrhage may 
occur.  The aberrant growth of leaky vessels is the result of local inflammatory responses leading 
to disruption of the balance of cytokines that control angiogenesis (Lim et al., 2008). 
Angiogenesis is a complex and coordinated process of the growth and sprouting of new blood 
vessels from pre-existing vasculature.  Although several angiogenic factors have been identified, 
VEGF family proteins, their receptors and intracellular signaling molecules appear to be the key 
mediators of angiogenesis (Kane et al., 2008).  
Exciting advances have been made in understanding the pathogenesis of AMD in recent years.  
Since 2004, several anti-VEGF medications, such as ranibizumab (Lucentis®), pegaptanib 
(Macugen®) and aflibercept (Eylea®) have been approved by the FDA for patients with wet 
AMD.  Although Eylea®, which is the most recently approved anti-VEGF medication for wet 
AMD, showed more than 95% of the subjects maintained vision defined as losing < 15 ETDRS 
letters for 12 months, only 30% of subjects gained > 15 ETDRS letters.  Moreover, 
approximately 30% of subjects still showed cystic intraretinal edema and subretinal fluid after 
12 months of treatment (Heier et al., 2012).  Therefore, anti-VEGF treatment may not represent 
the only pathway towards anti-angiogenesis.  New or novel approaches to inhibit angiogenesis 
are needed to elicit further improvements in visual acuity, macular edema, and quality of life in 
wet AMD patients. 
Endoglin (also known as CD105) is a member of the TGF-β receptor family that is expressed by 
proliferating endothelial cells and is considered as one of the essential factors for angiogenesis.  
Normal levels of endoglin are needed for endothelial cell proliferation (Guo et al., 2004; 
Warrington et al., 2005).  Endoglin expression is increased by cellular hypoxia through the 
production of hypoxia-inducible factor-1-α (HIF-1-α), and endoglin protects hypoxic cells from 
apoptosis (Li et al., 2003). 
Endoglin acts to modulate signaling of multiple kinase receptor complexes of the TGF-β 
superfamily, including TGF-β receptors, bone morphogenic protein (BMP) receptors, activin 
receptor-like kinases (ALKs) and activin receptors (Barbara et al., 1999).  In the absence of 
endoglin, activation of TGF-β receptors results in phosphorylation of SMAD 2/3 proteins that 
inhibit endothelial cell growth.  However, activation of endoglin by BMP modulates SMAD 
protein phosphorylation, through phosphorylation of SMAD 1/5/8 (Nolan-Stevaux et al., 2012).  
The end result is release of the growth inhibitory effects of TGF-β receptor activation on 
endothelial cells (Lebrin et al., 2004).  Similarly, endoglin is required for proliferation of 
endothelium in response to BMP.  BMP-9 and BMP-10 bind to endoglin and phosphorylate 
SMAD 1/5/8 to signal endothelial cell proliferation (Park et al., 2008).

DE-122 Injectable Solution

A recent study has demonstrated that endoglin is highly expressed in choroidal 
neovascularization (CNV) membranes surgically excised from wet AMD patients (Yasukawa et 
al., 2000). 
TRC105 is an anti-angiogenic mouse/human chimeric antibody against human endoglin 
developed by TRACON Pharmaceuticals, Inc.  TRC105 binds endoglin on proliferating 
endothelial cells to inhibit ligand binding by BMP, interrupting signal transduction, resulting in 
growth inhibition and apoptosis.  TRC105 also mediates antibody-dependent cell-mediated 
cytotoxicity (ADCC).  
A series of pharmacology studies in the TRACON oncology program have characterized 
TRC105 as a potent anti-angiogenic agent.  TRC105 alone inhibits VEGF- and bFGF-induced 
endothelial cell proliferation, suggesting that TRC105 can achieve similar therapeutic effects as 
anti-VEGF agents but through a different mechanism and specific or shared signaling pathway. 
It may be that TRC105 and anti-VEGF agents work synergistically to inhibit neovascularization 
and that TRC105 suppresses the escape mechanism underlying resistance to the long-term anti-
VEGF treatment, both of which are mediated by overexpression of endoglin.  
Several clinical trials for various cancer patients have been conducted by TRACON 
Pharmaceuticals, Inc.  As of December 06, 2015, over 438 patients had been treated with 
TRC105.  The majority of the patients have been Caucasian with ages ranging from 18 to 
87 years.  TRC105 has been well tolerated and exhibited a remarkably consistent adverse event 
profile, whether dosed as a single agent or dosed in combination with VEGF inhibitors or 
chemotherapy.  Activity of TRC105 in combination has been particularly noteworthy and 
represents the current development strategy. 
Santen is developing an ophthalmic formulation of TRC105, DE-122 injectable solution, suitable 
for intravitreal injection for the treatment of wet AMD. 
Santen has conducted a Phase I/II, open-label, dose-escalating, sequential cohort study assessing 
the safety, tolerability, immunogenicity, and bioactivity of a single IVT injection of DE-122 
injectable solution in the study eye of approximately twelve subjects with refractory wet AMD 
(Protocol 36-001).  Four dose levels of DE-122 were assessed in this Phase I/II study,  
0.5 mg/eye, 1.0 mg/eye, 2.0 mg/eye and 4.0 mg/eye.  The doses selected for use in this study 
were based on the results from non-clinical studies.  Additional information regarding the non-
clinical studies is provided in the Investigator’s Brochure. 
As of July 2017, all 12 subjects completed the study.  There were no reported SAEs.  No dose-
dependent events were reported and no new safety concerns were identified at all investigated 
doses. Ocular AEs were reported in 5 subjects (41.7%).  Most common AE was Subconjunctival 
haemorrhage (3 subjects, 25%) and all were considered to be due to the injection procedure.  
Santen believes that the Phase I/II study results mentioned above, in addition to the results of the 
non-clinical studies, supports the use of repeated IVT injections of the 2.0 mg and 4.0 mg 
concentrations of DE-122 in humans in the Phase II clinical trial (Protocol 36-002).

INVESTIGATIONAL PLAN 
7.1. 
Overall Study Design and Plan 
This is a randomized, double masked and active controlled study assessing the safety and 
efficacy of repeated intravitreal injections of DE-122 (2.0 mg or 4.0 mg) in combination with 
Lucentis® compared to Lucentis® monotherapy in subjects with wet AMD.  Approximately 
seventy six (76) subjects with wet AMD will be randomly assigned to one of three treatment 
arms:  
Arm 1: Sham + Lucentis® 0.5 mg (N=17) 
Arm 2: DE-122, 2.0 mg + Lucentis® 0.5 mg (N=31) 
Arm 3: DE-122, 4.0 mg + Lucentis® 0.5 mg (N=28) 
Subjects will receive 6 monthly intravitreal injections of DE-122 (2.0 mg or 4.0 mg) or Sham in 
the study eye, in combination with Lucentis®.  
The first 6 subjects will be randomized to Arm 1 or Arm 2 in a 1:1 ratio in Stage 1.  The Safety 
Review Team will review the safety parameters of the 6 subjects in Stage 1 and determine if the 
safety and tolerability at Week 4 are acceptable.  If so, enrollment will be continued in a 
1:2:2 ratio in the three arms for the remaining approximately 70 subjects in Stage 2.   
To be eligible, subjects must have a diagnosis of active CNV secondary to AMD, with some 
subfoveal component (CNV, fluid, or hemorrhage under the fovea) with lesions ≤ 12 disc areas 
and ≤ 50% hemorrhage in the study eye. Subjects must be previously treated (i.e., At least 3 IVT 
injections of Anti-VEGF for treatment naïve eyes or eyes adequately maintained on continuous 
intravitreal anti-VEGF therapy).  Subjects with Polypoidal Choroidal Vasculopathy (PCV) 
lesions will be allowed, but Retinal Angiomatous Proliferation (RAP) lesions will be excluded 
from this study. 
Screening Visit SD-OCT images and Fluorescein Angiography from Investigator-identified 
eligible subjects will be sent to the central reading center to confirm eligibility based on AMD 
lesion attributes specified in the protocol.  To balance the randomization, subjects will be 
stratified by subgroups on the reading center’s assessment of lesion type, up to approximately 
one third (1/3) of the subjects in each arm should have PCV in Stage 2.  Subjects must satisfy all 
other inclusion and exclusion criteria. 
Subjects must have best corrected visual acuity (BCVA) of 65 to 25 ETDRS letters (equivalent 
to 20/50 to 20/320 Snellen) in the study eye. 
Eligible subjects who are enrolled in the study will be seen for up to 14 visits. 
The Primary Analysis is planned when all subjects complete the Week 24 visit.  The Follow-up 
Analysis is planned at Week 32 to assess the number of anti-VEGF injections used for Rescue in 
addition to efficacy and safety data. 
Subjects are eligible for rescue with any anti-VEGF IVT injection during the Week 24 and Week 
28 if one of the following rescue criteria is met:

Selection of Concentrations in the Study 
In this clinical study, two dose levels of DE-122 (2.0 mg and 4.0 mg) are being tested in subjects 
with wet AMD.  The maximum amount of DE-122 that a subject can possibly receive is 24 mg 
over a 20 week period. Systemic exposure of DE-122 in this study given 6 times by IVT 
injection is anticipated to be significantly lower than the systemic exposure in over 500 cancer 

Protocol 36-002

Version 4.0 08JAN2019

Confidential 
subjects (most of whom received 10 mg/kg of TRC105 by weekly intravenous infusion).  
Therefore, no concerns regarding systemic toxicity are anticipated in this study. 
In pre-clinical studies, the highest tested DE-122 IVT dose of 5 mg/injection in the monkey eye 
would correlate to 10 mg/eye in human eyes due to the difference in volume, hence the 
difference in vitreous volume between human and monkey (2:1 ratio) conveys a margin of safety. 
In the mouse model of laser-induced CNV efficacy study, animals were given an IVT injection 
of DE-122 at 0.5, 1.5 and 5.0 μg/eye.  DE-122 inhibited CNV in a dose-dependent manner.  The 
highest effective dose was 5 μg/eye.  Considering the vitreous volume difference between human 
and mouse (~1000:1 ratio), a range of 0.5 to 5 mg/eye is considered a logical effective dose level 
for humans.   
In Phase I/II clinical study (Protocol 36-001), four dose levels of DE-122 (0.5 mg, 1.0 mg, 
2.0 mg and 4.0 mg) were tested in subjects with refractory wet AMD.  No dose-dependent events 
were reported and no new safety concerns were identified at all investigated doses. Most 
common AE was Subconjunctival haemorrhage (3 subjects, 25%) and all were considered to be 
due to the injection procedure.  
7.2. 
Number of Subjects 
Approximately 76 subjects (Arm 1: 17 subjects, Arm 2: 31 subjects, Arm 3: 28 subjects) with 
wet AMD will be enrolled at approximately 14 sites in the Philippines and the US.  The final 
number of subjects enrolled may be adjusted up to 80 based on drop-out rate. 
7.3. 
Treatment Assignment 
Two dose levels of DE-122 and Lucentis® will be administered by IVT injection in the study eye. 
 DE-122 injectable solution 2.0 mg (20 µL of 100 mg/mL)  
 DE-122 injectable solution 4.0 mg (40 µL of 100 mg/mL)  
 Ranibizumab (Lucentis®) 0.5 mg (50 µL of 10 mg/mL)  
7.4. 
Dose Adjustment Criteria 
The Safety Review Team will review safety parameters after the 6 subjects in Stage 1 have 
completed Week 4.  If the safety criteria for adjusting or stopping doses and the criteria for study 
termination are not met, the remaining subjects in three Arms will be enrolled in the study. 
7.4.1. 
Safety Criteria for 6 Subjects in Stage 1 
If more than one of the following events is observed by Week 4 visit in Stage 1, planned doses 
may be adjusted or stopped by the Safety Review Team. 
 Visual acuity loss from baseline defined as: 
 Loss of best corrected visual acuity (BCVA) of 30 or more letters not due to 
vitreous hemorrhage or injection procedure OR  
 Transition to no light perception (NLP) not due to injection procedure 
 Clinically significant inflammation defined as:

Study Procedures 
All subjects must sign a written ICF before participating in any study-related activity, and the 
subject will be assigned a unique screening number.  Central randomization will occur at Visit 1 
(Day 1) after a subject meets all eligibility requirements at Screening.  Each randomized subject 
will be assigned a unique subject number.  If a subject is discontinued from the study for any 
reason, the subject number will remain in effect and will not be reused. 
A Schedule of Events can be found below and detailed procedures for examinations can be found 
in Section 23.4, Appendix D – Procedures for Examinations.

TREATMENT OF SUBJECTS 
9.1. 
Description of Study Drug 
DE-122 is a chimeric anti-CD105 IgG1 antibody consisting of human Cκ and Cγ1 constant 
regions with murine Vκ and VH regions.  DE-122 is composed of two light chains of 213 amino 
acids and two heavy chains of 448 amino acids and has an approximate molecular weight of  
148 kDa.  DE-122 is utilized in this clinical study in a formulation designed for IVT injection. 
9.2. 
Concomitant Medications 
The use of any concomitant prescription or over-the-counter medication will be recorded during 
the study.  Therapy considered necessary for the subject’s welfare may be given at the discretion 
of the Clinical Investigator during the study.  Whenever possible, concomitant medications 
should be administered in dosages that remain constant throughout the study.  The generic name, 
indication, route of administration, frequency, dose, start date and stop date (if applicable) will 
be recorded for each medication. 
9.2.1. 
Prohibited Medications or Treatments 
Any treatments for wet AMD in the study eye other than DE-122 and Lucentis® are prohibited 
during the study. 
Any systemic treatments with anti-VEGF agents (e.g., bevacizumab) are prohibited during the 
study. 
The decision to administer a prohibited concomitant medication or treatment during the study 
should be made with the safety of the subject as the primary consideration.  Whenever possible, 
Santen should be notified before any prohibited medication or treatment is administered or if the 
permissibility of a specific medication or treatment is in question. 
9.2.2. 
Rescue Therapy 
Rescue therapy is defined as IVT injection of Anti-VEGF medication in the study eye.  
Eligibility for Rescue therapy to be determined as per rescue criteria in Section 7.1. 
9.3. 
Treatment Compliance 
In order to obtain efficacy and safety data, it is critical that the treatment regimen and visit 
schedule specified in this protocol are followed.  The Clinical Investigator is required to 
administer the DE-122 injection and Lucentis®, and is responsible for scheduling the subject for 
follow-up visits as specified in the protocol.  Study monitors will verify pertinent data to confirm 
the study is conducted according to the protocol. 
9.4. 
Randomization and Masking 
The first 6 subjects will be randomized in a 1:1 ratio to Arm 1 or Arm 2 at Visit 1 in Stage 1.  If 
the safety and tolerability at Week 4 for the 6 subjects are acceptable, randomization will be 

Protocol 36-002 
DE-122 Injectable Solution 
Version 4.0 08JAN2019 
54 of 106 
Confidential 
continued in a 1:2:2 ratio in the three arms for the remaining approximately 70 subjects in  
Stage 2.  
To balance the randomization, subjects will be stratified by subgroups on the reading center’s 
assessment of lesion type, up to approximately one third (1/3) of the subjects in each arm should 
have PCV in Stage 2. 
One of arms will have sham injection which is a mimic procedure of a real intravitreal injection 
but does not penetrate the eye.  To keep masking of the clinical trial, investigator and authorized 
study staffs must follow the points below.   
 The designated unmasked injecting physician and the designated unmasked injection 
staff must ensure any information regarding clinical study drugs injection during the 
study is inaccessible to other study staff. 
 The designated unmasked injecting physician and the designated unmasked injection 
staff cannot perform any assessments or examinations for the study other than clinical 
study drug injection procedures and examinations post drug injections. 
 Masked study staff not designated to study drug injections, including investigators, 
examiner and other clinical site staff, cannot participate in any procedures for clinical 
study drug injections and examinations post drug injections. 
In case of a medical emergency, the Principal Investigator or site staff may reveal the treatment 
information by unmasking in IWRS to know which treatment the subject has received.  The 
Principal Investigator should contact Santen, or Santen’s designee, before taking this measure, if 
there is sufficient time. Santen, or Santen’s designee, must be informed of all instances where the 
code is broken and of the reasons for such instances. 
Additionally, the adverse event or serious adverse event for which study treatment was 
unmasked should be reported to Santen Drug Safety (see Section 12.1).

<Investigational drug:  DE-122> 
Once an investigational drug vial number has been assigned to the subject, the vial of 
investigational drug with the assigned vial number will be removed from the refrigerator.  Care 
should be taken to protect the product from light.  Investigational drug should be drawn into the 
provided sterile single-use custom marked syringe (see Section 10.5) within 30 minutes after 
removing the vial from the refrigerator.  Investigational drug should be injected within 1 hour of 
being drawn up into the single-use syringe.  Study drug preparation should be performed by the 
designated injecting physician.  
Each vial contains enough DE-122 to inject one subject.  Each vial will be used one time only.  
Write the subject number on the carton label.  After use, return the vial in the unit carton, seal 
and initial the carton. 
<Investigational drug: Sham>

<Investigational drug:  DE-122> 
A sterile, single-use 250 μL syringe custom marked at 20 µL or 40 µL will be provided 
separately for IVT injection of DE-122.  Instructions for filling the syringe are as follows: 
1. Remove the sterile, single-use 250 μL syringe, custom marked at 20 µL or 40 µL, from 
the packaging. 
2. Attach a 19-gauge x 1 ½ inch filter needle to the syringe.  DE-122 is dispensed in a  
0.3 ml fill in a 2 mL vial.  See Figure 2. 
3. Using sterile technique, carefully draw up approximately 200 μL of DE-122 into the 
syringe.  (Sufficiently larger volume than 20 or 40 µL is needed to allow for dead space 
in syringe and needles prior to IVT injection). 
4. Remove the 19-gauge x 1½ inch filter needle from the syringe and replace with a  
30-gauge x 0.5-inch needle for the IVT injection.   
a. Ensure that the 30-gauge x 0.5-inch needle is affixed tightly to the syringe. 
b. Align the top edge of the red O-ring of the plunger with the 20 µL or 40 µL black 
mark on the syringe, expelling the excess fluid drawn up.  See Figure 3.

4. Use a sterile cotton-tipped applicator to remove excess fluid from the lower conjunctival 
sac. 
5. Take 2 sterile cotton tipped applicators and thoroughly soak with 0.5 % proparacaine 
topical anesthetic eye drops or an equivalent topical ophthalmic anesthetic.  Place the 
soaked applicators, side by side, gently but firmly on the conjunctival surface at the area 
of the entry site described below in Step 2 (Section 10.7) and hold in place for 
approximately 1 minute. 
6. Insert sterile eyelid speculum. 
7. Place sterile eye drape over study eye. 
<Investigational drug:  Sham> 
Eye preparation for Sham injection is the same as DE-122. 
10.7. 
Study Drug Administration  
<Concomitant drug: Lucentis®> 
Lucentis® administration to be done as per Lucentis® drug labeling. 
<Investigational drug: DE-122> 
1. Prior to starting the injection procedure, DE-122 should have been prepared as described 
in Section 10.4 and Section 10.5, and the study eye should have been prepared as 
described in Section 10.6.  
2. If the subject is phakic, the entry site is 4.0 mm from the limbus.  If the subject is 
pseudophakic or aphakic, the entry site is 3.5 mm from the limbus.  A caliper may be 
used to identify the needle entry site.  The entry site location for the investigational drug 
should be the same quadrant as the concomitant drug, but not at the same entry point.  
3. Insert the needle perpendicular to the eye wall at the location specified in Step 2  
(Section 10.7).  The needle should be inserted until the tip is just visible through the 
dilated pupil.  Note:  If paracentesis is considered necessary, it should be performed after 
injection of the DE-122 and noted in the source documents. 
4. Very slowly, inject the entire DE-122 dose volume (20 µL or 40 µL) and slowly 
withdraw the needle.  Do not pull back on the plunger at any time prior to withdrawing 
the needle. 
5. Briefly apply pressure for approximately 1 minute to the needle entry site with sterile 
cotton tipped applicator (may be skipped per Clinical Investigator’s discretion). 
6. Remove the eyelid speculum. 
7. Patch the study eye at the Clinical Investigator’s discretion. 
8. Prescribe fluoroquinolone equivalent antibiotic eye drops three times/day for two days 
following injection, to be initiated as soon as possible.

<Investigational drug:  Sham> 
Sham is injection that simulates DE-122 drug administration.  Sham intravitreal injections will 
be administered to subjects according to the same dosing schedule and procedure as DE-122 
injections.  However, the Sham intravitreal injection procedure will only mimic DE-122 
intravitreal injection in that the blunt end of an empty syringe is pressed against an anesthetized 
eye, instead of a needle attached to DE-122 syringe injected into the anesthetized eye.  Therefore, 
Step #3 and #4 of above DE-122 administration procedure will be skipped for the Sham injection. 
To keep masking of the study, investigator and authorized staff must follow the points described 
in Section 9.4.  
10.8. 
Study Drug Accountability 
The Principal Investigator is responsible for ensuring that an inventory is conducted upon receipt 
of the clinical supplies.  The temperature recorder from the shipment will be deactivated and 
authorized study staff will verify that the temperature was maintained at 2° to 8°C (36° to 46°F) 
during transit.   
The Principal Investigator will keep a current record of the inventory, storage conditions and 
dispensing of all study drugs.  This record will be made available to Santen (or designee) for the 
purpose of accounting for all clinical supplies.  Any significant discrepancy and/or deficiency 
must be recorded with an explanation.  
All supplies sent to the Principal Investigator must be accounted for and in no case will study 
drugs be used in any unauthorized situation.  It is the responsibility of the Principal Investigator 
to ensure that any used and unused supplies are available to Santen (or designee) throughout the 
study. 
10.9. 
Study Drug Handling and Return 
All investigational products including used/unused vials of DE-122/Lucentis® and syringes 
supplied by Santen/Representative will be fully accounted for by the monitor with the help of the 
unmasked person responsible for dispensing the DE-122 and will be returned to 
Santen/Representative or designee.  Accountability will be documented by use of drug 
accountability forms. 
Refer to Study Drug Manual for study drug handling.

ASSESSMENT OF SAFETY 
12.1. 
Adverse Events 
12.1.1. 
Definition of Adverse Events 
An AE is any untoward medical occurrence in a subject administered a pharmaceutical product 
and which does not necessarily have a causal relationship with the study drug(s).  An AE, 
therefore, can be an unintended sign (including an abnormal laboratory finding), symptom, or 
disease that has clinical significance and is temporally associated with the use of a medicinal 
(investigational) product, whether or not related to the medicinal (investigational) product. 
In clinical studies, an undesirable medical condition occurring at any time, including baseline or 
pre-treatment period, may be recorded as an AE even if no study drug has been administered. 
Any significant adverse change in a subject’s condition from baseline, regardless of causality, is 
to be considered an AE, unless the change is determined to be a continuation of a pre-existing 
condition that is documented in the subject’s medical history.  However, a clinically significant 
worsening in severity, intensity, or frequency of a pre-existing condition may indicate an AE.  In 
addition, all conditions that lead to hospitalizations, defined as an overnight hospital stay, are 
considered as AEs.  This includes planned elective surgeries.  
Lack of efficacy of the study drug(s) for the condition being investigated is not considered an AE 
unless a clinically significant change is assessed by the Clinical Investigator.  An elective 
surgical procedure scheduled or planned prior to study entry is not considered an AE if an 
overnight hospital stay is not required, and the underlying diagnosis for which surgery is to be 
performed should be captured in the medical history as a pre-existing condition.  The surgical 
procedure should also include the term “elective” in all reports.  
12.1.1.1. Assessment of Adverse Events 
Clinical Investigators will seek information on AEs at each subject contact.  Subjects should be 
asked, using a general, non-direct question, if there has been any change in their general health.  
Direct questioning and examination should then be performed as appropriate. 
Severity of the AE should be assessed according to the following criteria: 
Mild:  No interference with the subject’s daily activities; no medical intervention/therapy 
required 
Moderate:  Possible interference with the subject’s daily activities; no or minimal 
medical intervention/therapy required 
Severe:  Considerable interference with the subject’s daily activities; medical 
intervention/therapy required 
Regardless of severity, some AEs may also meet regulatory serious criteria.  Refer to definitions 
and reporting of serious adverse events (SAEs) in Section 12.1.2. 
A Clinical Investigator who is qualified in medicine must make the determination of the 
relationship of the study drug(s) to each AE (related or not related).  The Clinical Investigator 

Protocol 36-002 
DE-122 Injectable Solution 
Version 4.0 08JAN2019 
62 of 106 
Confidential 
should decide whether, in his or her medical judgment, there is a reasonable possibility that the 
DE-122, Lucentis® or the Sham injection could have caused the AE/SAE based on facts, 
evidence, scientific rationales, and clinical judgment.  When assessing causality, the Clinical 
Investigator may consider the following information when determining the relationship to the 
study drug(s) for each AE: mechanism of action, biologic plausibility, confounding risk factors 
(i.e., medical history, concomitant medications), temporal relationship, dechallenge/rechallenge, 
and lack of alternative explanation.  It should be specified if the AE is related to the injection 
procedure and not the study drug.  
 The AE may be recorded as Related to the study drug(s) if there is a plausible 
temporal relationship between the onset of the AE and administration of the study 
drug(s), and the AE cannot be readily explained by the subject’s clinical state, 
concurrent illness, or concomitant therapies; and/or the AE follows a known pattern 
of response to the study drug(s),; and/or the AE abates or resolves upon 
discontinuation of the study drug(s).  
 Reporting the AE as Not Related to study drug(s), may be considered if, for example, 
there is good evidence that the AE has an etiology other than the study drug(s)  
(e.g., pre-existing medical condition, underlying disease, concurrent illness, or 
concomitant medication); and/or the AE has no plausible temporal relationship to 
administration of the study drug(s) (e.g., cancer diagnosed 2 days after dose of study 
drug(s)). 
12.1.1.2. Reporting Adverse Events  
AEs, whether spontaneously reported by the subject or noted by authorized study personnel, will 
be recorded in the subject’s medical record and on the appropriate AE eCRF.  Each recorded AE 
will be described by its duration (i.e., start and end dates), frequency, severity, regulatory 
seriousness criteria if applicable, suspected relationship to the study drug(s), relation to injection 
procedure, location, actions taken and outcome. 
AEs that occur after any subject has provided written informed consent, before treatment, during 
treatment, or until study exit visit, whether or not they are related to the study, must be recorded.  
To improve the quality and precision of acquired AE data, Clinical Investigators should observe 
the following guidelines: 
 Whenever possible, use recognized medical terms when recording.  Do not use 
colloquialisms and/or abbreviations. 
 If known, record the diagnosis (i.e., disease or syndrome) rather than component 
signs and symptoms and /or laboratory or test findings (e.g., record congestive heart 
failure rather than dyspnea, rales, and cyanosis, and enlarged heart on chest x-ray).  
However, other events that are considered unrelated to an encountered syndrome or 
disease should be recorded as individual AEs (e.g., if congestive heart failure and 
severe headache are observed at the same time and are clinically unrelated, each event 
should be recorded as an individual AE). 
If the diagnosis is not known, then record the leading component sign, symptom or 
test finding and describe the other clinically related findings in the narrative 
description of the case.  A suspected diagnosis can be used and described as such 

Protocol 36-002 
DE-122 Injectable Solution 
Version 4.0 08JAN2019 
63 of 106 
Confidential 
(e.g., record suspected or probable myocardial infarction); this has to be updated in 
the clinical database once the diagnosis is confirmed.  
AEs occurring secondary to other events (e.g., sequelae) should be identified by the 
primary cause.  A primary AE, if clearly identifiable, generally represents the most 
accurate clinical term.  If a primary AE is recorded, events occurring secondary to the 
primary event should be described in the narrative description of the case.  For 
example: 
The subject developed orthostatic hypotension and subsequently fainted and fell to 
the floor wherein she experienced a head trauma and neck pain. 
The primary AE in this example is orthostatic hypotension.  The fall, head trauma and 
neck pain should be described in the narrative description of the case.  
 For intermittent events (e.g., intermittent headache), the event onset date should be 
recorded as the date the subject first started to experience the event and resolution 
date should reflect when the last occurrence resolved or stopped.  Separate AEs for 
each event should not be recorded.  For example, if a subject experienced headache 
on 14SEP2015 lasting for three hours, then subsequently experienced intermittent 
episodes of headache every day for approximately 3 hours until 21SEP2015, then the 
AE date of onset is 14SEP2015 and the resolution date is 21SEP2015. 
 For intermittent events, record the maximum severity of the individual events.  For 
example, if a subject complains of intermittent headaches for one week and the 
severity of each headache ranges from mild to moderate, then the severity would be 
moderate. 
 For intermittent hospitalizations occurring for a primary AE (e.g., in a subject with 
multiple sclerosis, commonly known for its relapsing and remitting course, in some 
cases leading to multiple hospital confinements), the subsequent hospitalizations 
should be described in the narrative description of the case.  
 If treatment was initiated, include the treatment and duration of the medication(s) in 
the eCRF. 
12.1.2. 
Serious Adverse Events 
SAEs are defined as any findings that suggest a significant hazard, contraindication, side effect, 
or precaution.  Any adverse event is considered a serious adverse event if it results in any of the 
following outcomes: 
 Death 
 Life threatening: 
A life-threatening event is any event that places the subject at immediate risk of death 
from the event as it occurred; it does not refer to an event that hypothetically might 
have caused death if it were more severe. 
 Hospitalization, at the minimum an overnight stay  
 A persistent or significant disability/incapacity  

Protocol 36-002 
DE-122 Injectable Solution 
Version 4.0 08JAN2019

Confidential 
 A congenital anomaly/birth defect 
 Other medically significant events:  
Other medically significant events are events that may not result in death, be life-
threatening, or require hospitalization but may be considered a serious adverse drug 
experience when, based upon appropriate medical judgment, they may jeopardize the 
subject and may require medical or surgical intervention to prevent one of the 
outcomes listed above.  
 Sight threatening event:  
A sight-threatening event is any event that places the subject at immediate risk of 
permanently losing vision in either eye as a direct result of the event.  It is defined as 
a loss of ≥ 30 letters or 6 lines of vision from Baseline.  
12.1.2.1. Reporting Serious Adverse Events 
A SAE eCRF must be completed with as much information available within 24 hours of 
knowledge of the event. 
To improve the quality and precision of acquired SAE data, Clinical Investigators should observe 
the following guidelines: 
 Death - Death is an outcome of an event.  The event that resulted in the death should 
be recorded and reported as a SAE. 
 Hospitalizations for Surgical or Diagnostic Procedures - The illness 
leading to the surgical or diagnostic procedure should be recorded as the 
SAE, not the procedure itself.  The procedure should be captured in the case 
narrative as part of the action taken in response to the illness. 
When new significant information (including the outcome of the event) is obtained, the Clinical 
Investigator should enter the information directly into the eCRF within 24 hours or as soon as 
possible after knowledge of the information. 
Depending on the nature and seriousness of the AE, Santen may request additional 
documentation, for example, copies of the ophthalmic and medical record of the subject as well 
as results of laboratory tests.  If the subject was hospitalized, the site should summarize the 
hospital discharge summary and provide to Santen upon request. 
12.1.2.2. Expedited Reporting of Serious Adverse Events 
Santen (or designee) will provide the Principal Investigator with a reporting cover letter and an 
anonymized MedWatch 3500A or CIOMs form as appropriate for expedited reporting of SAEs 
to the IRB or IEC and the Philippines or the US regulatory agency.  The Principal Investigator is 
responsible for receiving and reviewing expedited safety reports, submitting expedited safety 
reports to the IRB or IEC, and maintaining copies of expedited safety reports in the study 
records.

12.1.3. 
Events of Special Interest 
Events of Special Interest (ESIs) are events that may require special attention for the purposes of 
on-going patient safety review during this study.  The following are considered ESIs and should 
be reported on the appropriate eCRF with as much information as available within 24 hours of 
knowledge of the event: 
 Study medication administration error – Study medication administration errors 
determined to be significant by the Clinical Investigator will be reported and 
evaluated as ESIs.  Examples of study medication administration errors may include, 
but are not limited to:  overdose of study medication and administration of study 
medication from an incorrect kit. 
 Pregnancy - There are no controlled data with the investigational product in human 
pregnancy.  It is required that females of childbearing potential use effective 
contraception during the study and recommended for 12 weeks after the completion 
of the study.  Any pregnancy occurring during study treatment should be reported and 
the subject removed from the study.  The subject should be followed until the end of 
pregnancy or until the end of the study, whichever is longer. 
 Ocular telangiectasia and bleeding events – There is no data showing that the 
investigational product is related to these events.  However, these are seen in the 
Osler-Weber-Rendu (OWR) syndrome, a genetic condition that causes endoglin 
dysfunction.  DE-122 binds to and suppresses human endoglin, thus information 
about the ocular manifestations of OWR are of value in predicting possible ocular 
adverse events following IVT injection of DE-122.  The following events will be 
considered ESIs and the subject followed until the end of the study or resolution of 
the event.  
 Ocular telangiectasia (Conjunctival and intraocular) 
 Intra- and extra-ocular bleeding (hemorrhage) not attributed to the injection 
procedure and/or AMD 
 Common systemic OWR signs: Epistaxis, gingival bleeding and mucocutaneous 
telangiectasia 
12.1.4. 
Follow-up of Adverse Events 
All reported AEs should be followed until resolution or until the subject’s participation in the 
study ends.  Subjects with the following types of events should be followed by the Investigator 
until the event is determined to be resolved, irreversible, chronic, stable, the subject withdraws 
consent, or no further information can be reasonably obtained.  
 On-going SAEs 
 On-going ESIs (excluding medication errors not resulting in AEs) 
 Early termination and withdrawal from the study due to study drug related AEs 
In addition, on a case by case basis, Santen (or designee) may request follow up beyond the 
scheduled exit visit.

Slit-lamp Biomicroscopy 
The Clinical Investigator will assess Slit-lamp biomicroscopy examination using Slit-lamp 
microscope.  On the visit of any IVT treatment, a biomicroscopy examination will be performed 
prior to Lucentis® injection and a second one within 30 minutes after DE-122 or Sham injection.  
This will be also applied for the post IVT injection of Rescue treatment. 
12.2.6. 
Intraocular Pressure 
IOP will be measured by applanation tonometry and reported in millimeters of mercury (mmHg).  
On the visit of any IVT injection, IOP will be measured before Lucentis® and 40 (±10) minutes 
after Lucentis® injection.  If post-injection IOP is > 21 mmHg or increased ≥ 10 mmHg from  
pre-injection IOP, the IOP will be measured again 60 (±10) minutes following Lucentis® 
injection.  If there is an increase of ≥ 10 mmHg at 60 (±10) minutes post-injection, the IOP 
increase of ≥ 10 mmHg will be reported as an AE.  
Moreover, IOP will be measured after DE-122 or Sham injection.  If post-DE-122 or Sham 
injection IOP is > 21 mmHg or increased ≥ 10 mmHg from pre-injection IOP, the IOP will be 
measured again 60 (±10) minutes following injection.  If there is an increase of ≥ 10 mmHg at 60 
(±10) minutes post-injection compared to pre-injection IOP, the IOP increase of ≥ 10 mmHg will 
be reported as an AE.  This will be also applied for the post IVT injection of Rescue treatment.

Randomization  
The first 6 subjects will be randomized to Arm 1 and Arm 2 in a 1:1 ratio in Stage 1.  If the 
safety and tolerability at Week 4 are acceptable, remaining approximately 70 subjects will be 
randomized to all Arms in a 1:2:2 ratio in Stage 2.  To balance the randomization, subjects will 
be stratified by subgroups on the central reading center’s assessment of lesion type, up to 
approximately one third (1/3) of the subjects in each arm should have PCV in Stage 2. 
16.2.4. 
Study Eye 
The study eye must meet all inclusion and exclusion criteria, including confirmation by the 
central reading center.  If both eyes are eligible based on inclusion and exclusion criteria, the 
study eye is defined as the eye with worse vision.  If both eyes have the same vision, the right 
eye (OD) should be determined as the study eye. 
16.3. 
Study Populations 
The following study populations are defined for analysis:  Intention-to-treat (ITT) and Safety. 
ITT Population: The ITT population will include all randomized subjects in the study.

Appendix C - Declaration of Helsinki 
WMA Declaration of Helsinki - Ethical Principles for Medical Research Involving Human 
Subjects 
Adopted by the 18th WMA General Assembly, Helsinki, Finland, June 1964 
and amended by the: 
29th WMA General Assembly, Tokyo, Japan, October 1975 
35th WMA General Assembly, Venice, Italy, October 1983 
41st WMA General Assembly, Hong Kong, September 1989

59th WMA General Assembly, Seoul, Republic of Korea, October 2008 
64th WMA General Assembly, Fortaleza, Brazil, October 2013 
 
Preamble 
1. The World Medical Association (WMA) has developed the Declaration of Helsinki as a 
statement of ethical principles for medical research involving human subjects, including 
research on identifiable human material and data. 
The Declaration is intended to be read as a whole and each of its constituent paragraphs 
should be applied with consideration of all other relevant paragraphs. 
2. Consistent with the mandate of the WMA, the Declaration is addressed primarily to 
physicians.  The WMA encourages others who are involved in medical research 
involving human subjects to adopt these principles.  
General Principles 
3. The Declaration of Geneva of the WMA binds the physician with the words, “The health 
of my patient will be my first consideration,” and the International Code of Medical 
Ethics declares that, “A physician shall act in the patient's best interest when providing 
medical care.” 
4. It is the duty of the physician to promote and safeguard the health, well-being and rights 
of patients, including those who are involved in medical research.  The physician's 
knowledge and conscience are dedicated to the fulfilment of this duty. 
5. Medical progress is based on research that ultimately must include studies involving 
human subjects. 
6. The primary purpose of medical research involving human subjects is to understand the 
causes, development and effects of diseases and improve preventive, diagnostic and 
therapeutic interventions (methods, procedures and treatments).  Even the best proven 
interventions must be evaluated continually through research for their safety, 
effectiveness, efficiency, accessibility and quality. 

Protocol 36-002 
DE-122 Injectable Solution 
Version 4.0 08JAN2019 
90 of 106 
Confidential 
7. Medical research is subject to ethical standards that promote and ensure respect for all 
human subjects and protect their health and rights. 
8. While the primary purpose of medical research is to generate new knowledge, this goal 
can never take precedence over the rights and interests of individual research subjects. 
9. It is the duty of physicians who are involved in medical research to protect the life, 
health, dignity, integrity, right to self-determination, privacy, and confidentiality of 
personal information of research subjects.  The responsibility for the protection of 
research subjects must always rest with the physician or other health care professionals 
and never with the research subjects, even though they have given consent. 
10. Physicians must consider the ethical, legal and regulatory norms and standards for 
research involving human subjects in their own countries as well as applicable 
international norms and standards.  No national or international ethical, legal or 
regulatory requirement should reduce or eliminate any of the protections for research 
subjects set forth in this Declaration. 
11. Medical research should be conducted in a manner that minimizes possible harm to the 
environment. 
12. Medical research involving human subjects must be conducted only by individuals with 
the appropriate ethics and scientific education, training and qualifications.  Research on 
patients or healthy volunteers requires the supervision of a competent and appropriately 
qualified physician or other health care professional. 
13. Groups that are underrepresented in medical research should be provided appropriate 
access to participation in research. 
14. Physicians who combine medical research with medical care should involve their patients 
in research only to the extent that this is justified by its potential preventive, diagnostic or 
therapeutic value and if the physician has good reason to believe that participation in the 
research study will not adversely affect the health of the patients who serve as research 
subjects. 
15. Appropriate compensation and treatment for subjects who are harmed as a result of 
participating in research must be ensured. 
Risks, Burdens and Benefits  
16. In medical practice and in medical research, most interventions involve risks and 
burdens. 
Medical research involving human subjects may only be conducted if the importance of 
the objective outweighs the risks and burdens to the research subjects. 
17. All medical research involving human subjects must be preceded by careful assessment 
of predictable risks and burdens to the individuals and groups involved in the research in 
comparison with foreseeable benefits to them and to other individuals or groups affected 
by the condition under investigation. 
Measures to minimize the risks must be implemented.  The risks must be continuously 
monitored, assessed and documented by the researcher. 

Protocol 36-002 
DE-122 Injectable Solution 
Version 4.0 08JAN2019 
91 of 106 
Confidential 
18. Physicians may not be involved in a research study involving human subjects unless they 
are confident that the risks have been adequately assessed and can be satisfactorily 
managed. 
When the risks are found to outweigh the potential benefits or when there is conclusive 
proof of definitive outcomes, physicians must assess whether to continue, modify or 
immediately stop the study. 
Vulnerable Groups and Individuals 
19. Some groups and individuals are particularly vulnerable and may have an increased 
likelihood of being wronged or of incurring additional harm. 
All vulnerable groups and individuals should receive specifically considered protection. 
20. Medical research with a vulnerable group is only justified if the research is responsive to 
the health needs or priorities of this group and the research cannot be carried out in a non-
vulnerable group.  In addition, this group should stand to benefit from the knowledge, 
practices or interventions that result from the research. 
Scientific Requirements and Research Protocols  
21. Medical research involving human subjects must conform to generally accepted scientific 
principles, be based on a thorough knowledge of the scientific literature, other relevant 
sources of information, and adequate laboratory and, as appropriate, animal 
experimentation.  The welfare of animals used for research must be respected. 
22. The design and performance of each research study involving human subjects must be 
clearly described and justified in a research protocol. 
The protocol should contain a statement of the ethical considerations involved and should 
indicate how the principles in this Declaration have been addressed. The protocol should 
include information regarding funding, sponsors, institutional affiliations, potential 
conflicts of interest, incentives for subjects and information regarding provisions for 
treating and/or compensating subjects who are harmed as a consequence of participation 
in the research study. 
In clinical trials, the protocol must also describe appropriate arrangements for post-trial 
provisions. 
Research Ethics Committees 
23. The research protocol must be submitted for consideration, comment, guidance and 
approval to the concerned research ethics committee before the study begins.  This 
committee must be transparent in its functioning, must be independent of the researcher, 
the sponsor and any other undue influence and must be duly qualified.  It must take into 
consideration the laws and regulations of the country or countries in which the research is 
to be performed as well as applicable international norms and standards but these must 
not be allowed to reduce or eliminate any of the protections for research subjects set forth 
in this Declaration.  
The committee must have the right to monitor ongoing studies.  The researcher must 
provide monitoring information to the committee, especially information about any 

Protocol 36-002 
DE-122 Injectable Solution 
Version 4.0 08JAN2019 
92 of 106 
Confidential 
serious adverse events.  No amendment to the protocol may be made without 
consideration and approval by the committee. After the end of the study, the researchers 
must submit a final report to the committee containing a summary of the study’s findings 
and conclusions. 
Privacy and Confidentiality 
24. Every precaution must be taken to protect the privacy of research subjects and the 
confidentiality of their personal information. 
Informed Consent 
25. Participation by individuals capable of giving informed consent as subjects in medical 
research must be voluntary.  Although it may be appropriate to consult family members 
or community leaders, no individual capable of giving informed consent may be enrolled 
in a research study unless he or she freely agrees. 
26. In medical research involving human subjects capable of giving informed consent, each 
potential subject must be adequately informed of the aims, methods, sources of funding, 
any possible conflicts of interest, institutional affiliations of the researcher, the 
anticipated benefits and potential risks of the study and the discomfort it may entail, post-
study provisions and any other relevant aspects of the study.  The potential subject must 
be informed of the right to refuse to participate in the study or to withdraw consent to 
participate at any time without reprisal.  Special attention should be given to the specific 
information needs of individual potential subjects as well as to the methods used to 
deliver the information. 
After ensuring that the potential subject has understood the information, the physician or 
another appropriately qualified individual must then seek the potential subject’s freely-
given informed consent, preferably in writing.  If the consent cannot be expressed in 
writing, the non-written consent must be formally documented and witnessed. 
All medical research subjects should be given the option of being informed about the 
general outcome and results of the study. 
27. When seeking informed consent for participation in a research study the physician must 
be particularly cautious if the potential subject is in a dependent relationship with the 
physician or may consent under duress.  In such situations the informed consent must be 
sought by an appropriately qualified individual who is completely independent of this 
relationship. 
28. For a potential research subject who is incapable of giving informed consent, the 
physician must seek informed consent from the legally authorized representative.  These 
individuals must not be included in a research study that has no likelihood of benefit for 
them unless it is intended to promote the health of the group represented by the potential 
subject, the research cannot instead be performed with persons capable of providing 
informed consent, and the research entails only minimal risk and minimal burden. 
29. When a potential research subject who is deemed incapable of giving informed consent is 
able to give assent to decisions about participation in research, the physician must seek 
that assent in addition to the consent of the legally authorized representative.  The 
potential subject’s dissent should be respected. 

Protocol 36-002 
DE-122 Injectable Solution 
Version 4.0 08JAN2019 
93 of 106 
Confidential 
30. Research involving subjects who are physically or mentally incapable of giving consent, 
for example, unconscious patients, may be done only if the physical or mental condition 
that prevents giving informed consent is a necessary characteristic of the research group.  
In such circumstances the physician must seek informed consent from the legally 
authorized representative.  If no such representative is available and if the research cannot 
be delayed, the study may proceed without informed consent provided that the specific 
reasons for involving subjects with a condition that renders them unable to give informed 
consent have been stated in the research protocol and the study has been approved by a 
research ethics committee.  Consent to remain in the research must be obtained as soon as 
possible from the subject or a legally authorized representative. 
31. The physician must fully inform the patient which aspects of their care are related to the 
research.  The refusal of a patient to participate in a study or the patient’s decision to 
withdraw from the study must never adversely affect the patient-physician relationship. 
32. For medical research using identifiable human material or data, such as research on 
material or data contained in biobanks or similar repositories, physicians must seek 
informed consent for its collection, storage and/or reuse.  There may be exceptional 
situations where consent would be impossible or impracticable to obtain for such 
research.  In such situations the research may be done only after consideration and 
approval of a research ethics committee. 
Use of Placebo 
33. The benefits, risks, burdens and effectiveness of a new intervention must be tested 
against those of the best proven intervention(s), except in the following circumstances: 
Where no proven intervention exists, the use of placebo, or no intervention, is acceptable; 
or 
Where for compelling and scientifically sound methodological reasons the use of any 
intervention less effective than the best proven one, the use of placebo, or no intervention 
is necessary to determine the efficacy or safety of an intervention 
and the patients who receive any intervention less effective than the best proven one, 
placebo, or no intervention will not be subject to additional risks of serious or irreversible 
harm as a result of not receiving the best proven intervention. 
Extreme care must be taken to avoid abuse of this option. 
Post-Trial Provisions 
34. In advance of a clinical trial, sponsors, researchers and host country governments should 
make provisions for post-trial access for all participants who still need an intervention 
identified as beneficial in the trial.  This information must also be disclosed to 
participants during the informed consent process. 
Research Registration and Publication and Dissemination of Results 
35. Every research study involving human subjects must be registered in a publicly 
accessible database before recruitment of the first subject. 

Protocol 36-002 
DE-122 Injectable Solution 
Version 4.0 08JAN2019 
94 of 106 
Confidential 
36. Researchers, authors, sponsors, editors and publishers all have ethical obligations with 
regard to the publication and dissemination of the results of research.  Researchers have a 
duty to make publicly available the results of their research on human subjects and are 
accountable for the completeness and accuracy of their reports.  All parties should adhere 
to accepted guidelines for ethical reporting.  Negative and inconclusive as well as 
positive results must be published or otherwise made publicly available.  Sources of 
funding, institutional affiliations and conflicts of interest must be declared in the 
publication.  Reports of research not in accordance with the principles of this Declaration 
should not be accepted for publication. 
Unproven Interventions in Clinical Practice 
37. In the treatment of an individual patient, where proven interventions do not exist or other 
known interventions have been ineffective, the physician, after seeking expert advice, 
with informed consent from the patient or a legally authorized representative, may use an 
unproven intervention if in the physician's judgment it offers hope of saving life, re-
establishing health or alleviating suffering.  This intervention should subsequently be 
made the object of research, designed to evaluate its safety and efficacy.  In all cases, 
new information must be recorded and, where appropriate, made publicly available.

Appendix D - Procedures for Examinations 
23.4.1. 
Demographics/Eligibility, Medical/Surgical History and Concomitant 
Medication 
Demographics/Eligibility, medical/surgical history and concomitant medication will be obtained 
through subject interviews at Screening (Day -14 to Day -1).  Medical history and concomitant 
medications will be obtained through subject interviews at each visit.  
23.4.2. 
Physical Examination 
A full body systematic physical examination will be conducted during Visit 0/Screening  
(Day -14 to Day -1), Visit 11 (Week 24) and Visit 13 (Week 32).  Clinical Investigator or an 
external internist will confirm subject’s overall condition noting any abnormalities by a review 
of the following systems: e.g., head, eyes, ears, nose and throat (HEENT), cardiopulmonary, 
endocrine, gastrointestinal, musculoskeletal/rheumatic, neurologic/psychiatric, dermatologic, 
hepatic/renal systems, and other. 
The Clinical Investigator will assess subject’s overall condition to determine qualification for 
study entry considering possible class effects of DE-122.  Newly noted abnormalities or 
worsening of previously noted abnormalities found at Study Exit, or at any safety assessment 
visit, will be assessed as an AE.  The Clinical Investigator should use his or her clinical judgment 
for appropriate treatment and/or medical referral. 
23.4.3. 
Vital Signs 
Blood pressure and heart rate will be measured at each visit except Visit 2 (Day 3), Visit 9 
(Week 20 + 2 days) and Visit10 (Week 20 + 7 days) using an automated or manual blood 
pressure monitor.  Systolic and diastolic blood pressures will be recorded in millimeters of 
mercury (mmHg) and heart rate will be recorded in beats per minute (bpm).  
In accordance with the recommendations of the Joint National Committee on Prevention, 
Detection, Evaluation, and Treatment of High Blood Pressure  
(US_Dept_Health_And_Human_Services, 2004), the following measurement procedure will be 
used to measure vital signs: 
 Subject should not smoke or ingest caffeine within the 30-minute period immediately 
before the measurement. 
 Subject should be seated quietly in a chair with the back supported, feet on the floor, 
arm bared, and arm supported at heart level. 
 Begin the measurement after at least 5 minutes of rest. 
 To ensure an accurate measurement, use an appropriately sized cuff.  The cuff 
bladder should encircle at least 80 % of the arm.  Many adults need a large cuff. 
 Take two (2) systolic/diastolic pressure and heart rate measurements separated by at 
least 30 seconds.  Record each measurement in the subject’s source document. 

Protocol 36-002 
DE-122 Injectable Solution 
Version 4.0 08JAN2019

Confidential 
 If the two pressure measurements differ by 5 mmHg or less, then the average of the 
two becomes the recorded pressure.  For example, if the two measurements are 
120/90 and 125/95, then 122.5/92.5 is the recorded systolic/diastolic pressure. 
 If the two pressure measurements differ by more than 5 mmHg, then a third reading 
measurement is made, and the average of the three becomes the recorded pressure.  
For example, if the three measurements are 115/90, 124/96, and 120/92, then 
119.7/92.7 is the recorded systolic/diastolic pressure.  The recorded blood pressure 
will be the average of the measurements. 
 Record the heart rate.  For heart rate, the average of the two (or three, if performed) 
measurements obtained becomes the recorded heart rate.  
23.4.4. 
EKG 
EKGs will be recorded at Visit 0/Screening (Day -14 to Day -1) and reviewed for abnormalities 
by the Clinical Investigator prior to enrollment. EKGs will also be performed at Visit 3 (Week 1), 
Visit 10 (Week 20 + 7 days), Visit 11 (Week 24) and Visit 13 (Week 32). 
23.4.5. 
Best Corrected Visual Acuity 
ETDRS chart will be used to examine BCVA at each study visit except Visit 2 (Day 3), Visit 9 
(Week 20 + 2 days) and Visit10 (Week 20 + 7 days).  See Study Procedures manual for the 
detailed procedure for measuring visual acuity. 
23.4.6.

M-CHARTS™ will be used to examine metamorphopsia at each study visit except Visit 2  
(Day 3), Visit 9 (Week 20 + 2 days) and Visit10 (Week 20 + 7 days).  Two types of values which 
are vertical metamorphopsia score (MV) and horizontal metamorphopsia score (MH) will be 
assessed. See instruction for measuring metamorphopsia. 
23.4.7.

Intraocular Pressure 
IOP will be measured by applanation tonometry at each study visit except Visit 2 (Day 3), Visit 9 
(Week 20 + 2 days) and Visit 10 (Week 20 + 7 days).   
At visits with IVT injection, IOP will be measured before Lucentis® injection and 40 (±10) 
minutes after injection.  If post-Lucentis® injection IOP is > 21 mmHg or increased ≥ 10 mmHg 
from pre-injection IOP, the IOP measurement will be repeated at 60 (±10) minutes following 
Lucentis® injection. 
If post-injection IOP at 60 (±10) minutes is ≥ 30 mmHg OR increased ≥ 10 mmHg from pre-
injection IOP, the subject should be prescribed a topical IOP-lowering medication until he or she 
returns for follow-up per the Clinical Investigator’s discretion, and the event will be reported as 
an AE. 
IOP will be also measured after DE-122 or Sham injection.  If post-DE-122 or Sham injection 
IOP is > 21 mmHg OR increased ≥ 10 mmHg from pre-Lucentis® injection at 40 (±10) minutes 
after injection, the IOP measurement will be repeated at 60 (±10) minutes after the injection.  If 
post-DE-122 or Sham injection IOP at 60 (±10) minutes is ≥ 30 mmHg OR increased

≥ 10 mmHg from pre-Lucentis® injection IOP, the subject should be prescribed a topical IOP-
lowering medication, and the IOP elevation will be reported as an AE. If post-injection IOP at  
60 (±10) minutes is > 21 mmHg AND < 30 mmHg, the subject will be managed according to the 
Clinical Investigator’s discretion. 
If rescue IVT injection is performed, IOP will be measured 40 (±10) minutes after the injection.  
If post-injection IOP is > 21 mmHg OR increased ≥ 10 mmHg from pre-injection IOP, IOP 
measurement will be repeated at 60 (±10) minutes post-injection.  If post-injection IOP at 60 
(±10) minutes is ≥ 30 mmHg OR increased ≥ 10 mmHg from pre-injection IOP, the subject 
should be prescribed a topical IOP-lowering medication, and the IOP elevation will be reported 
as an AE. Per the Clinical Investigator’s discretion, the subject can return for follow-up.  If post-
injection IOP at 60 (±10) minutes is > 21 mmHg AND < 30 mmHg, the subject will be managed 
according to the Clinical Investigator’s discretion. 
The applanation tonometer must be calibrated for accuracy before the first subject undergoes 
screening, and periodically until the last subject has exited the study.  For checking calibration, 
follow the manufacturer’s instructions.  
The following IOP measurement procedure is in accordance with the procedure used in the 
Ocular Hypertension Treatment Study (Gordon et al., 2001) at each visit: 
At least two, and sometimes three, consecutive measurements are made to obtain a determination 
of intraocular pressure.  Each IOP measurement should be recorded in the subject’s source 
document and in the eCRFs. 
 If the first 2 measurements differ by less than 3 mmHg, report the mean of the first  
2 measurements.  For example, if the two measurements are 22 and 23, then 22.5 is 
the final recorded IOP. 
 However, if the first 2 measurements differ by greater than or equal to 3 mmHg, take 
a third measurement and report the median IOP (the median is the middle 
measurement after arraying the measurements from low to high).  For example, if the 
three measurements are 15, 19, and 16, then 16 is the final recorded IOP. 
23.4.9. 
Indirect Ophthalmoscopy 
Indirect ophthalmoscopy will be performed for each eye at each visit except Visit 2 (Day 3), 
Visit 9 (Week 20 + 2 days) and Visit10 (Week 20 + 7 days) with pupil dilation. 
Indirect ophthalmoscopy will be used to examine the retina at each study visit.  Indirect 
ophthalmoscopy will be performed prior to and within 30 minutes after each DE-122 or Sham 
injection.  Areas to be assessed include cup to disc ratio, retina, macula and choroid, and 
vitreous.  This will be also applied for the post IVT injection of Rescue treatment. 
Cup/Disc Ratio 
The cup/disc ratio will be determined by the examiner and recorded using two decimal places 
(e.g., 0.80).
