Multicenter Study Assessing the Efficacy and Safety of DE-117 Ophthalmic Solution 0.002% 
Compared with Timolol Maleate Ophthalmic Solution 0.5% in Subjects with Glaucoma or 
Ocular Hypertension - Spectrum 4 Study 
Protocol Number: 011710IN 
Number of Subjects (planned): Approximately 400 adult subjects (200 in each treatment arm) 
with Open-Angle Glaucoma (OAG) or Ocular Hypertension (OHT) and up to 30 pediatric 
subjects (15 in each treatment arm) with pediatric glaucoma or OHT will be randomized in this 
study

OHT after 1 week of treatment 
Safety objective:  
To determine the safety of DE-117 Ophthalmic Solution 0.002% as compared to Timolol 
Maleate Ophthalmic Solution 0.5% in subjects with glaucoma or OHT 
Duration of Treatment: 3 months 
Methodology:   
This is a Phase III, randomized, double-masked, active-controlled, parallel-group, multi-center 
study. Subjects diagnosed with glaucoma or OHT who meet eligibility criteria at Visit 1 
(Screening) will washout of their current topical IOP-lowering medication(s), if any. After 
completing the required washout period, subjects will return for Visit 2 (Baseline, Day 1). 
Subjects who meet all eligibility criteria at baseline will be randomized to receive treatment for 
3 months. 
Approximately 400 adult subjects and up to 30 pediatric subjects with glaucoma or OHT who 
meet all eligibility criteria will be randomized in a 1:1 ratio to receive either: 
 DE-117 Ophthalmic Solution 0.002% QD (20:00) and Vehicle QD (08:00), or 
 Timolol Maleate Ophthalmic Solution 0.5% BID (20:00 & 08:00). 
Study Design 
 
This study will consist of a Screening Period of up to 35 days including a washout period of up 
to 28 days (+ 7 days window) and a 3-month Double-Masked Treatment Period. 
At the Screening visit (Visit 1), subjects will be screened against the inclusion and exclusion 
criteria. Eligible subjects will be instructed to discontinue use of all IOP-lowering medications, 

Protocol 011710IN, Spectrum 4 Study 
DE-117 Ophthalmic Solution 
Version 1.1 13JULY2018

Page 6 of 103 
if any, during a washout period as follows (up to +7 days as a window is allowed): 
 Miotics: 7 days 
 Oral/topical Carbonic Anhydrase Inhibitors (CAIs): 7 days 
 Alpha agonists: 14 days 
 Alpha/beta agonists: 14 days 
 Alpha antagonists (α1 blocker): 28 days 
 Beta antagonists (β blocker, including αβ blockers): 28 days 
 Prostaglandin Analogs (PGA): 28 days 
 Rho kinase inhibitor: 28 days 
 Combination drugs: The longest washout period of the individual component will be 
used. 
During the required washout period, subjects who discontinue their current treatment may, if the 
Investigator deems it necessary, be treated with a short-acting IOP lowering agent, topical 
Carbonic Anhydrase Inhibitor (CAI), e.g., brinzolamide or dorzolamide eye drops, one drop 
twice daily. Topical CAI treatment must be stopped 1 week before the randomization at Visit 2 
(Baseline, Day 1). An interim safety visit during the washout period (mid-washout visit; Visit 
1a) may be performed during the washout period if, in the Investigator’s opinion, a subject’s 
IOP may be of concern during the washout period. If subjects are treated with a topical CAI 
during the washout period, mid-washout visit (Visit 1a) is recommended to be performed. 
Final eligibility for randomization will be determined at Visit 2 (Baseline) after all necessary 
washout from prior IOP-lowering medications have been completed. Subjects who have not 
used any IOP-lowering medication for the last 28 days, including treatment-naive subjects, must 
have ≥ 1 day between their screening visit and Visit 2 (Baseline).  
At Visit 2, baseline IOP will be measured for both eyes at 08:00 (±60 min), 10:00 (±60 min) and 
16:00 (±60 min). The study eye will be the eye that qualifies per eligibility criteria at Visit 2. If 
both eyes meet the eligibility criteria, the eye with the higher mean diurnal IOP at Visit 2 will be 
designated as the study eye. If both eyes meet the eligibility criteria and have the same mean 
diurnal IOP, the right eye will be designated as the study eye. Both eyes should be treated with 
the study medication for the duration of the study, even if only one eye is eligible per IOP 
inclusion criteria. For pediatric subjects, if only one eye has a diagnosis of glaucoma or 
OHT, the fellow eye doesn’t have to be treated by the study medications for the duration 
of the study. 
Double-Masked Treatment Period (3 months):  
Approximately 400 eligible adult subjects and up to 30 pediatric subjects will be randomized to 
receive either DE-117 0.002% QD in the evening and vehicle QD in the morning or Timolol 
Maleate 0.5% BID in a 1:1 ratio. Subjects will be treated for 3 months with scheduled visits at 
Visits 2, 3, 4 and 5 (Baseline, Week 1, Week 6 and Month 3). 
At Visit 2 (Baseline), subjects will receive their first dose of study medication (study eye drops) 
as per their assigned/randomized study treatment at 20:00 (±60 min). The next day, subjects will

Version 1.1 13JULY2018 
Confidential 
Page 7 of 103 
subsequently dose with their assigned study medication at 08:00 (±60 min), and 20:00 (±60 
min). At each scheduled follow-up visit, subjects will receive their morning dose of study 
medication/eye drops following the 08:00 IOP measurement at the investigative site (the 
doctor’s office). 
Timolol Maleate Ophthalmic Solution 0.5% was chosen as the active control because it has 
previously been proven to be effective for the reduction of elevated IOP in patients with 
glaucoma or OHT and is approved for these indications. 
IOP will be measured at 08:00, 10:00 and 16:00 (±60 min). At these scheduled visits, best-
corrected visual acuity (BCVA) and slit-lamp biomicroscopy will be performed just prior to the 
08:00 IOP measurement. Ophthalmoscopy (fundus examination) will be performed after the 
16:00 IOP measurement. Vital signs (resting blood pressure and pulse rate) will be collected in 
sitting position anytime at visit 1, and approximately 08:00 for Visits 2, and 5 before the 
morning dose. 
Pharmacogenomics/Genomics: 
Subjects who consent to the optional pharmacogenomics/genomics laboratory study will 
provide a blood sample for future testing. The purpose of this exploratory research is to identify 
possible genetic markers associated with the study medication(s) and/or ocular conditions. 
Masking: 
This is a double-masked study. The subjects, Investigators, Examiners and Santen personnel 
involved in the conduct of the study will be masked to the study treatment. An authorized 
unmasked study staff member who is not the Investigator or Examiner at the investigative site 
will dispense and collect study medication(s) and will query about dosing compliance. Subjects 
will be instructed not to show the eye drop bottles or discuss the eye drop to either the 
Investigator or the Examiner or other study subjects. The active control treatment (Timolol 
Maleate) containers will be over-labeled and packaged in the same secondary package (e.g., 
cardboard carton) as the investigational treatment (DE-117). All subjects will receive a bottle 
labeled “morning” for the morning dose and a bottle labeled “evening” for the evening dose. 
However, the DE-117/Vehicle arm will receive the vehicle (i.e., “morning” bottle) at the 
morning dose, while the Timolol Maleate arm receives the active treatment (i.e., “morning” 
bottle) at the morning dose. Each eligible subject will be assigned to receive a numbered study 
medication kit as assigned by Central randomization via Interactive Response Technology 
(Medidata BALANCE) at Visit 2 (Baseline) and at Visit 4 (Week 6). 
Inclusion Criteria for ADULT subjects: 
At Visit 1 (Screening), the subjects must meet all of the following inclusion criteria: 
1. Provide signed written informed consent on the Institutional Review Board (IRB)/Ethics 
Committee (EC) approved Informed Consent Form (ICF).

Criteria for Evaluation: 
Efficacy: 
Efficacy will be assessed by evaluating IOP at scheduled time points (08:00, 10:00 and 16:00) at 
all scheduled visits with the exception of the Screening visit.  
Safety: 
Safety will be assessed by adverse events (AEs), BCVA, slit-lamp biomicroscopy, 
ophthalmoscopy, iris color/eyelash/eyelid examination, resting blood pressure and pulse rate.  
Other: 
Subject demographics, baseline characteristics, medical history, concomitant medications, 
exposure to study medication, and pregnancy for females of childbearing potential will be 
summarized. 
Efficacy Endpoints: 
Primary Efficacy Endpoint 
The primary efficacy endpoint is the IOP in the study eye measured at the specified time points: 
08:00, 10:00 and 16:00 at Week 1, Week 6 and Month 3 (Visits 3, 4 and 5).  
Key Secondary Efficacy Endpoints 
 Mean diurnal IOP in the study eye at Month 3 (Visit 5) 
 Mean diurnal IOP in the study eye at Week 1 (Visit 3) 
Other Secondary Efficacy Endpoints 
 Change and percent change from baseline in IOP at each timepoint/post-baseline 
visit 
 Change and percent change from baseline in mean diurnal IOP at each post-baseline 
visit 
 Having a  mean diurnal IOP reduction ≥ 20%, ≥ 25%, or ≥ 30% from Baseline  
(Visit 2) at each post-baseline visit 
 Having a mean diurnal IOP ≤ 18 mmHg at each post-baseline visit 
Safety Endpoints 
Safety will be evaluated by the following parameters: 
 Incidence of ocular and systemic AEs

 Blood pressure and pulse rate  
 BCVA 
 Slit-lamp biomicroscopy findings: anterior chamber cells, anterior chamber flare, lid 
hyperemia, lid edema, conjunctival hyperemia, conjunctival chemosis, corneal 
edema, corneal staining, keratic precipitates, lens, anterior synechiae of iris, posterior 
synechiae of iris 
 Ophthalmoscopy 
 Iris color/eyelash/eyelid 
Statistical Methods: 
The sample size calculation was based on a two-sided Type I error rate of 5% and a non-
inferiority margin of 1.5 mmHg. Assuming a between-treatment difference of 0 mmHg, a 
standard deviation (SD) of 4.0 mmHg, and a correlation coefficient of 0.6 among repeated 
measures, approximately 400 adult subjects in total (200 subjects per treatment arm) will 
provide 90% power to demonstrate non-inferiority of DE-117 Ophthalmic Solution 0.002% to 
Timolol Maleate Ophthalmic Solution 0.5%. 
A mixed-effects model for repeated measures (MMRM) will be fitted and 95% confidence 
interval for least square mean difference between the DE-117/Vehicle arm and the Timolol 
Maleate arm at each scheduled time point of each post-baseline visit up to Month 3 will be 
estimated. Non-inferiority is achieved if the upper limit of the two-sided 95% confidence 
interval for the difference in the mean IOP (0.002% DE-117 - Timolol Maleate) is ≤ 1.5 mmHg 
at all nine time points and ≤ 1.0 mmHg in majority (5 or more) of the 9 time points. 
Separate statistical analysis for pediatric subjects may be performed depending on the number of 
pediatric subjects enrolled in this study.

INTRODUCTION 
Glaucoma represents a group of related diseases frequently associated with elevated IOP. When 
left untreated, glaucoma can lead to retinal ganglion cell death and optic nerve damage, resulting 
in progressive and irreversible loss of vision. Glaucoma is the second leading cause of blindness 
worldwide. In 2013, the global prevalence of glaucoma for population aged 40 to 80 years was 
3.54%. The number of people (aged 40 to 80 years) with glaucoma worldwide was estimated to 
be 64.3 million, increasing to 76.0 million in 2020 and 111.8 million in 2040 (Tham et al., 2014). 
It affects one in two hundred people aged fifty or younger and one in ten over the age of eighty 
(Resnikoff et al., 2004). Similarly in Japan, glaucoma is the first leading cause of blindness and 
it’s prevalence is 5.0% (POAG 3.9%, PACG 0.6%, secondary glaucoma 0.5%) and OHT 0.8% in 
population over the age of forty (Iwase et al., 2004; Yamamoto et al., 2005). 
Although currently there is no cure for OAG, results from multiple studies, including the 
Advanced Glaucoma Intervention Study (AGIS) (AGIS_Investigators, 2000), the Ocular 
Hypertension Treatment Study (OHTS) (Kass et al., 2002), and the Early Manifest Glaucoma 
Trial (EMGT) (Leske et al., 2003), and United Kingdom Glaucoma Treatment Study (UKGTS) 
(Garway-Heath et al., 2015) have demonstrated that treating elevated IOP with topical ocular 
hypotensive agents is effective in delaying or preventing disease progression. The lowering of 
IOP is currently the only method for reducing the risk of glaucomatous visual field loss and 
remains the primary goal of therapy. 
Several classes of ocular hypotensive medications exist today and are differentiated by their 
mechanism of action at the cellular/molecular level. These include miotics, β-adrenergic receptor 
antagonists (β-blockers), CAIs, -adrenergic receptor agonists (-agonists), and prostaglandin 
analogues (PGAs). The pharmacodynamic effect of these medications can differ substantially, as 
some affect aqueous humor production (β-blockers, -agonists, and CAIs) while others affect the 
outflow pathway (miotics, PGs, and -agonists). In general, PGAs are recommended as the first-
choice agent for most eyes with OHT and OAG. However as disease progresses and maintaining 
target IOP becomes difficult, more than one drug is needed to achieve optimum benefit and reach 
target IOP. Surgical interventions, including laser surgery, shunting of aqueous humor to an 
appropriate locale, and filtering surgery, are available options for treating insufficiently 
controlled IOP. In such instances pharmacotherapy may be continued as well. 
In some patients, treatment with a single IOP-lowering compound is not sufficient to obtain 
optimal IOP control. Adjunctive or combination therapy using different classes of drugs is often 
employed in order to achieve additional IOP-lowering effects. Moreover, consistent lowering of 
IOP over a 24-hour period has not yet been fully realized. If achieved, this could also contribute 
to slowing of disease progression. Therefore, new pharmacologic agents with new mechanism of 
action are needed. 
Santen has developed an ophthalmic topical formulation of omidenepag isopropyl (UR-7385) for 
the reduction of elevated IOP in patients with OHT or OAG. DE-117 is a pro-drug of the 
pharmacologically active acid metabolite, UR-7276, a synthetic non-prostanoid agonist of 
prostaglandin E2 (PGE2) receptor, subtype 2 (EP2). PGE2 has been shown to markedly reduce 
IOP when applied topically to human and animal eyes (Bito, 2001). PGE2, its analogues and 
receptor agonists are thought to mediate the IOP-lowering effect by relaxing the ciliary muscle

and increasing outflow of aqueous humor through the uveo-scleral pathway (Yamaji et al., 2005). 
Very recently, Fuwa et al., demonstrated that DE-117 lowers the IOP through a novel 
meachnism of action: that is, through both conventional and uveoscleral outflows (Fuwa et al., 
2017). Currently approved IOP- lowering medications such as latanoprost (Latanoprost 
Ophthalmic Solution, 0.005%; NDA 20-597) lower IOP by enhancing uveoscleral outflow only, 
but do so through effects on a receptor for PGF2α. Unlike latanoprost and other approved 
prostaglandin F receptor (FP) agonists that are synthetic prostanoid analogues, DE-117 is a non-
prostanoid chemical compound. 
To date, Santen has completed seven clinical studies including three clinical studies (33-001,  
33-002, 33-003) in the U.S. and four clinical studies (01171502, 01171503, 01171504, 
01171506) in Japan with DE-117 in healthy adult subjects, or subjects with OAG or OHT to 
evaluate the efficacy and safety of DE-117. DE-117 Ophthalmic Solution 0.002% appeared to be 
well tolerated and efficacious in IOP lowering. As a result, it was chosen to advance into the 
phase III clinical development program in the US.  
Additional information on DE-117 Ophthalmic Solution, including the results of nonclinical and 
clinical studies can be found in the Investigator’s Brochure. 
The proposed study is a randomized, double-masked, active-controlled, parallel group, multi-
center, Phase III study. The total duration of treatment is 3 months. The objective is to 
investigate the efficacy and safety of DE-117 Ophthalmic Solution 0.002% compared with 
Timolol Maleate Ophthalmic Solution 0.5% in subjects with glaucoma or OHT.

INVESTIGATIONAL PLAN 
7.1. 
Overall Study Design 
This is a Phase III, randomized, double-masked, active-controlled, parallel-group and multi-
center study investigating the efficacy and safety of DE-117 Ophthalmic Solution 0.002% in 
subjects with glaucoma or OHT. 
See the study design diagram in Figure 1. This study will consist of a Screening Period of up to 
35 days including a washout period of up to 28 days (+ 7 days window) and a 3-month Double-
Masked Treatment Period.  
Approximately 400 adult subjects and up to 30 pediatric subjects s with glaucoma or OHT who 
meet all eligibility criteria will be randomized in a 1:1 ratio to receive either: 
 DE-117 Ophthalmic Solution 0.002% QD (20:00) and Vehicle QD (08:00), or 
 Timolol Maleate Ophthalmic Solution 0.5% BID (20:00 & 08:00). 
In the Double-Masked Treatment Period, Timolol Maleate Ophthalmic Solution 0.5% will be 
used as active control. 
Figure 1: 
Study Design 
 
At the Screening visit (Visit 1), subjects will be screened against the inclusion and exclusion 
criteria. Eligible subjects will be instructed to discontinue use of all IOP-lowering medications, if 
any, during a washout period as follows (up to +7 days as a window is allowed):  
 Miotics: 7 days 
 Oral/topical Carbonic Anhydrase Inhibitors (CAIs): 7 days 

Protocol 011710IN, Spectrum 4 Study

Page 32 of 103 
 Alpha agonists: 14 days 
 Alpha/beta agonists: 14 days 
 Alpha antagonists (α1 blocker): 28 days 
 Beta antagonists (β blocker, including αβ blockers): 28 days 
 Prostaglandin Analogs (PGA): 28 days 
 Rho kinase inhibitor: 28 days 
 Combination drugs: The longest washout period of the individual component will be 
used. 
During the required washout period, subjects who discontinue their current treatment may, if the 
Investigator deems it necessary, be treated with a short-acting IOP lowering agent, topical CAI, 
e.g., brinzolamide or dorzolamide eye drops, one drop twice daily. Topical CAI treatment must 
be stopped 1 week before the randomization at Visit 2 (Baseline, Day 1). An interim safety visit 
during the washout period (mid-washout visit; Visit 1a) may be performed during the washout 
period if, in the Investigator’s opinion, a subject’s IOP may be of concern during the washout 
period. If subjects are treated with a topical CAI during the washout period, mid-washout visit 
(Visit 1a) is recommended to be performed. 
Final eligibility for randomization will be determined at Visit 2 (Baseline) after all necessary 
washouts from prior IOP-lowering medications have been completed. Subjects who have not 
used any IOP-lowering medication for the last 28 days, including treatment-naive subjects, must 
have ≥ 1 day between their screening visit and Visit 2 (Baseline).  
At Visit 2, baseline IOP will be measured for both eyes at 08:00 (±60 min), 10:00 (±60 min) and 
16:00 (±60 min). The study eye will be the eye that qualifies per eligibility criteria at Visit 2. If 
both eyes meet the eligibility criteria, the eye with the higher mean diurnal IOP at Visit 2 will be 
designated as the study eye. If both eyes meet the eligibility criteria and have the same mean 
diurnal IOP, the right eye will be designated as the study eye. Both eyes should be treated with 
the study medication for the duration of the study, even if only one eye is eligible per IOP 
inclusion criteria. For pediatric subjects, if only one eye has a diagnosis of glaucoma or OHT, 
the fellow eye doesn’t have to be treated by the study medications for the duration of the 
study. 
Double-Masked Treatment Period (3 months): 
Approximately 400 eligible adult subjects and up to 30 pediatric subjects will be randomized to 
receive either DE-117 0.002% QD in the evening and vehicle QD in the morning or Timolol 
Maleate 0.5% BID in a 1:1 ratio. Subjects will be treated for 3 months with scheduled visits at 
Visits 2, 3, 4 and 5 (Baseline, Week 1, Week 6 and Month 3). 
At Visit 2 (Baseline), subjects will receive their first dose of study medication (study eye drops) 
as per their assigned/randomized study treatment at 20:00 (±60 min). The next day, subjects will 
subsequently dose with their assigned study medication at 08:00 (±60 min), and 20:00 (±60 min). 
At each scheduled follow-up visit, subjects will receive their morning dose of study 
medication/eye drops following the 08:00 IOP measurement at the investigative site (the doctor’s 
office).

Timolol Maleate Ophthalmic Solution 0.5% was chosen as the active control because it has 
previously been proven to be effective for the reduction of elevated IOP in patients with 
glaucoma or OHT and is approved for these indications. 
IOP will be measured at 08:00, 10:00 and 16:00 (±60 min). At these scheduled visits, BCVA and 
slit-lamp biomicroscopy will be performed just prior to the 08:00 IOP measurement. 
Ophthalmoscopy (fundus examination) will be performed after the 16:00 IOP measurement. 
Vital signs (resting blood pressure and pulse rate) will be collected in sitting position anytime at 
Visit 1, and approximately 08:00 for Visits 2, and 5 before the morning dose. 
Pharmacogenomics/genomics: 
Subjects who consent to the optional pharmacogenomics/genomics laboratory study will provide 
a blood sample for future testing. The purpose of this exploratory research is to identify possible 
genetic markers associated with the study medication(s) and/or ocular conditions. 
7.2. 
Number of Subjects 
Approximately 400 adult subjects and up to 30 pediatric subjects are planned to be enrolled in 
this study. 
7.3. 
Treatment Assignment 
Subjects are randomized to one of two following treatment arms in a 1:1 ratio during the Double-
Masked Treatment Period: 
 DE-117 Ophthalmic Solution 0.002% QD (20:00) and Vehicle QD (08:00) 
 Timolol Maleate Ophthalmic Solution 0.5% BID (20:00 & 08:00)

a. 
Informed Consent Form and the Assent Form must be signed and dated before study procedures are performed. Informed 
consent for the optional pharmacogenomics/genomics laboratory research study may be obtained at any visit prior to study 
exit. 
b. 
Prostaglandin-naive subjects are defined as subjects who are not known to have used prostaglandin as their glaucoma 
treatment. The previous use of prostaglandin should be confirmed by either subject’s medical records or subject history. 
c. 
A urine pregnancy test will be conducted for all female subjects of childbearing potential. 
d. 
Vital signs (resting blood pressure and pulse rate) will be collected in anytime at Visit 1 (Screening), and approximately 
08:00 for Visit 2 (Baseline), and Visit 5 before the morning dose.  
e. 
Refraction will be performed at the screening visit if the pediatric subject is able to cooperate. Autorefraction is also 
acceptable. If more than 10 letters in BCVA are lost compared to the screening visit level, then refraction should be 
performed again if the pediatric subject is able to cooperate. BCVA examination will be completed before IOP measurement 
at 08:00. BCVA will be performed for the pediatric subjects who are able to cooperate using an age-appropriate eye chart 
and method (e.g. ETDRS chart, LEA symbols chart with logMAR notation, Tumbling E’s with logMAR notation, Landolt’s 
broken rings with LogMAR notation, fix and follow) under normal room illumination. Same eye chart should be used for a 
given subject throughout the study. 
f. 
Biomicroscopy examination must be completed before IOP is measured at 08:00. Aqueous flare and cell evaluation will be 
performed before instillation of fluorescein.

g. 
IOP measurements will be performed at 08:00, 10:00 and 16:00 (±60 min) at all visits except for Visit 1 and the optional 
Visit 1a (screening and mid-washout). IOP will be measured with age-appropriate tonometers (e.g. Goldmann applanation 
tonometer, a Perkins tonometer, or a tonopen, or iCare tonometer etc.) to the extent the subject is able to cooperate.  
h. 
Pachymetry will be performed after IOP measurement at Visit 1 (Screening) if the subject is able to cooperate. Subject must 
have sufficiently clear cornea that allows for a complete ophthalmic exam to be enrolled if pachymetry is not able to be 
obtained. 
i. 
Eye photograph will be taken at Visits 2 (Baseline), and 5 (Month 3) if the subject is able to cooperate.  
j. 
Gonioscopy will be performed at Visit 1 (Screening) if the subject is able to cooperate. If unable to cooperate, historical 
gonioscopy performed within 12 months prior to screening and documented in the subject’s records is acceptable. 
Gonioscopy performed at Visit 1 (Screening) should occur after IOP measurement. 
k. 
Visual field test will be performed if the subject is able to cooperate. If visual field test was performed within 3 months (90 
days) prior to screening and was documented in the subject’s records, no additional screening visual field test is necessary.  
l. 
Ophthalmoscopy will be performed if the subject is able to cooperate. Ophthalmoscopy will be performed at Visits 1, 2, and 
5 (i.e. Screening, Baseline and Month 3) after the 16:00 IOP measurements. Ophthalmoscopy will be performed with pupil 
dilation at Visit 1 and Visit 5/exit or early termination. Dilation of the pupil will be performed after the 16:00 IOP 
measurement. 
m. Blood sampling for the pharmacogenomics/genomics laboratory research study may be performed at any visit after the 
pharmacogenomics/genomics informed consent is obtained, subject is randomized and study drug dosing has begun. 
n. 
Optional at unscheduled visit, required for early terminated subjects.  
 
Guidance for the visual acuity and IOP measurements in pediatric subjects are shown in

7.4.1. 
Visit 1 (Screening) 
 Explain the purpose and conduct of the study to the subject and obtain written 
individual informed consent. Informed consent for the optional 
pharmacogenomics/genomics laboratory research study may be obtained at any visit 
prior to blood sampling. Ensure the subject understands that if he/she does not wish to 
provide a blood sample for the pharmacogenomics/genomics laboratory research 
study that their decision will have no influence on their participation in the main 
study. 
For pediatric subjects, written informed consent must be provided by the 
parent/legal guardian, and assent should be provided by the pediatric subjects. 
The evaluation of whether or not a child can give assent should not solely be 
based on chronological age, but should also depend on factors such as 
developmental stage, intellectual capacity and disease experience/understanding. 
 Prepare the list of screening/registration of subjects. 
 Obtain demographics. 
 Obtain medications, procedures/therapies and medical history including all lifetime 
ocular medical history to the extent possible, non-ocular medical history within 5 
years, diagnosis, ocular surgical history, current ocular and systemic conditions. 
 Obtain urine and perform urine pregnancy test, if the subject is a female of child-
bearing potential. 
 As per Schedule of Events and Procedures Table 3 (for adult subjects) or Table 4 
(for pediatric subjects), perform the following procedures or assessments (all 
ophthalmic procedures to be performed in both eyes): 
 Vital signs (blood pressure/pulse rate)  
 Refraction  
 BCVA (before IOP measurement) 
 Biomicroscopy (before IOP measurement) 
 IOP 
 Pachymetry (after IOP measurement)  
 Ophthalmoscopy with pupil dilation (after IOP measurement) 
 Gonioscopy  
 Visual field  
 Determine if the subject meets eligibility criteria. 
 If the subject meets eligibility criteria and is still willing to continue the study, 
discontinue any current IOP-lowering medications if any according to the following 
schedule (up to +7 days as a window is allowed): 
 Miotics: 7 days 

Protocol 011710IN, Spectrum 4 Study 
DE-117 Ophthalmic Solution 
Version 1.1 13JULY2018 
Confidential 
Page 39 of 103 
 Oral/topical Carbonic Anhydrase Inhibitors (CAIs): 7 days 
 Alpha agonists: 14 days 
 Alpha/beta agonists: 14 days 
 Alpha antagonists (α1 blocker): 28 days 
 Beta antagonists (β blocker, including αβ blockers): 28 days 
 Prostaglandin Analogs (PGA): 28 days 
 Rho kinase inhibitor: 28 days 
 Combination drugs: The longest washout period of the individual component will 
be used. 
 During the required washout period, subjects who discontinue their current treatment 
may, if the Investigator deems it necessary for safety, be treated with a topical CAI, 
e.g., brinzolamide or dorzolamide eye drops, one drop twice daily. Topical CAI 
treatment must stop 1 week before the randomization at Visit 2 (Baseline, Day 1). 
 An interim safety visit, mid-washout visit (Visit 1a), may be performed during the 
washout period if, in the Investigator’s opinion, a subject’s IOP causes any safety 
concerns during the washout period. If subjects are to be treated with topical CAI in 
the week before Visit 2 (Baseline, Day 1), mid washout visit (Visit 1a) is 
recommended to be performed. 
 The eligibility visit (Visit 2) will be scheduled at the end of the washout period for 
those subjects on prior IOP-lowering medications. 
 Subjects who have not used an IOP-lowering medication for the last 28 days, 
including treatment-naive subjects, will need a wait period of ≥ 1 day before their 
Visit 2 (Baseline, Day 1). 
 If a subject does not require washout from an IOP-lowering medication, but they 
use contact lenses in either eye for adult subjects or in the eye being considered 
for study treatment for pediatric subjects, they will need a wait period of ≥ 2-3 
weeks (2 weeks for soft contact lens wearers, and 3 weeks for rigid contact lens 
wearers) with no contact use before their Visit 2 (Baseline, Day 1). 
 Schedule the eligible subject to return for Visit 2 (Baseline, Day 1) after the required 
wait/washout period. 
 A subject who does not meet eligibility criteria or will not otherwise continue in the 
study is considered a screen failure. 
7.4.2. 
Visit 1a (Optional, Washout Period) 
 Visit 1a is an interim safety visit (referred to as mid-washout visit) that may be 
performed during the washout period if, in the Investigator’s opinion, a subject’s IOP 
causes any safety concern during washout period.

Subject Withdrawal Criteria 
An early termination occurs when a subject who provides written informed consent ceases 
participation in the study, regardless of circumstances, before the completion of the study. 
Subjects may be voluntarily discontinued from study medication or withdrawn from the study at 
any time for any reason. In addition, the Principal Investigator or Medical Monitor may 
discontinue the study drug administration or terminate a subject’s study participation due to any 
of the following reasons: 
 AE (e.g., not compatible with study continuation) 
 Non-compliance with study drug 
 Lack of efficacy (e.g., IOP exceeds 34 mmHg in either eye after randomization) 
 Progressive disease 
 Protocol deviation (e.g., not fulfilling eligibility criteria) 
 Pregnancy 
 Voluntary withdrawal by subject at any time for any reason 
 Lost to follow-up (e.g., no contact is possible) 
 Death 
 Other 
If the study drug administration is discontinued prior to Visit 5, they should be encouraged to 
still participate in all follow-up study visits until Visit 5 on an observational basis. 
If the study drug administration is discontinued prior to Visit 5, then to the extent possible, all 
procedures for Early Termination will be performed on the day of early drug discontinuation as 
per Table 3 (for adult subjects) or Table 4 (for pediatric subjects). Subjects who are discontinued 
from the study early will not be replaced.

Page 54 of 103 
 If artificial sodium chloride/potassium chloride ophthalmic solution, cataract 
treatment agents, Vitamin B12 formulation, over-the-counter dry eye artificial 
tears/drops are concomitantly used, there must be an interval of at least 5 
minutes between use of these ocular medications and use of the study medication. 
 All systemic medications for ocular hypotensive (e.g., oral or intravenous CAI, oral 
glycerol) during the study duration. 
 Any ocular, periocular, inhaled, nasal or systemic corticosteroids including joint 
injection, etc. during the study duration. 
 Lacrimal/punctal occlusion via plug (s) or cautery during the study duration.  
 Initiate or modify any systemic or topical medication known to affect IOP  
(e.g., β-adrenergic antagonists, α-adrenergic agonists, calcium channel blockers, ACE 
inhibitors, and ARB) within the first 30 days prior to Visit 1 (Screening) and during 
the study duration. 
 Contact lenses within 2-3 weeks prior to Visit 2 (Baseline, Day 1) until end of 
treatment in either eye for adult subjects or in the eye being considered for study 
treatment for pediatric subjects (2 weeks for soft contact lens wearers, and 3 weeks 
for rigid contact lens wearers). 
 Any ocular surgery or ocular laser treatment within 180 days prior to Visit 1 
(Screening) and throughout the study in either eye for adult subjects or in the eye 
being considered for study treatment for pediatric subjects. 
 Participation in any other clinical trial involving an investigational product within 
4 weeks prior to Visit 1 (Screening) and during the study. 
The decision to administer a prohibited medication or therapy should be made with the safety of 
the subject as the primary consideration. Whenever possible, Medical Monitor should be notified 
before any prohibited medication or therapy is administered. There may be additional prohibited 
therapies not mentioned above. Medical Monitor should be contacted if the permissibility of a 
specific medication or therapy is in question. 
9.3. 
Treatment Compliance 
To obtain reliable efficacy and safety data, the following precautions will be taken to ensure 
compliance with the treatment regimen during the study: 
 Subjects will receive verbal and written instructions for proper instillation of the 
study medication, the dosing regimen, and the conditions of the study medication 
storage.  
 Subjects will be reminded at study visits to consistently dose at the same time of the 
day 
 Twice daily at 08:00 and 20:00 [±60min] through Visit 2 to 5  
 Subjects will be reminded of the evening instillation of the study drug on the day 
before Visit 3 through Visit 5/Early Termination respectively. 

Protocol 011710IN, Spectrum 4 Study 
DE-117 Ophthalmic Solution 
Version 1.1 13JULY2018 
Confidential 
Page 55 of 103 
 Subjects will be reminded that the morning instillation of the study drug at each visit 
through Visit 3 to 5 will be done at the clinic.  
 For adult subjects, since subjects must have a diagnosis of OAG or OHT in both eyes, 
both eyes should be treated for the duration of the study, even if only one eye is 
eligible per IOP inclusion criteria. 
For pediatric subjects, if only one eye has a diagnose of glaucoma or OHT, the 
fellow eye doesn’t have to be treated by the study medications for the duration of 
the study.  
 Subjects will be queried regarding compliance with the protocol’s dosing regimen at 
Visit 3 through Visit 5/Early Termination.  
 Subjects will be counseled on proper dosing procedures and dosing schedule if the 
subject’s compliance is not 100%. 
 A subject’s dosing compliance for a specific period is determined by the total number 
of days that subject followed the proper dosing procedures and dosing schedule. 
Stoppage of study medication use, overdosing of study medication, incorrect time of 
study medication administration, will be noted as non-compliance. The subject’s 
dosing compliance will be recorded in the subject’s source documents at Visit 3 
through Visit 5/Early Termination.  
 Subjects may be discontinued from the study at the discretion of the Investigator if 
the subject cannot be brought into compliance. 
9.4. 
Randomization and Masking 
A stratified permuted-block randomization will be employed to randomize eligible subjects in a 
1:1 ratio to either DE-117/Vehicle arm or Timolol Maleate arm. Two strata will be constructed 
based on age (adult: ≥ 18 years; pediatric: < 18 years).  
The randomization schedule will be generated and implemented using central randomization via 
Interactive Response Technology (Medidata BALANCE). Each randomized subject will receive 
numbered study medication kits as assigned by BALANCE. 
This is a double-masked study. The subjects, Investigators, Examiners and Santen personnel 
involved in the conduct of the study will be masked to the study treatment. An authorized 
unmasked study staff member who is not the Investigator or Examiner at the investigative site 
will dispense and collect study medication(s) and will query about dosing compliance. Subjects 
will be instructed not to show the eye drop bottles or discuss the eye drop to either the 
Investigator or the Examiner or other study subjects. The active control treatment (Timolol 
Maleate) containers will be over-labeled and packaged in the same secondary package (e.g., 
cardboard carton) as the investigational treatment (DE-117). All subjects will receive a bottle 
labeled “morning” for the morning dose and a bottle labeled “evening” for the evening dose. 
However, the DE-117/Vehicle arm will receive the vehicle (i.e., “morning” bottle) at the 
morning dose, while the Timolol Maleate arm receives the active treatment (i.e., “morning” 
bottle) at the morning dose. 
In case of a medical emergency, the Principal Investigator may reveal the treatment information 
by unmasking through Medidata BALANCE to know which treatment the subject has received.

The Principal Investigator (or his/her designee) 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 AE or SAE for which study treatment was unmasked should be reported to 
Santen Pharmacovigilance.

in each eye at approximately 20:00 (±60min) and 08:00 (±60min) daily for 3 months.  
10.6. 
Study Medication Accountability 
The Principal Investigator is responsible for ensuring that an inventory is conducted upon receipt 
of the clinical supplies. The temperature chart recorder from the shipment will be deactivated, 
and the Investigator (or his/her designee) will verify that the temperature was maintained at 2° to 
8°C (36° to 46°F) during transit. In the event of a temperature excursion or any study 
medications damaged during transit, the Investigator (or his/her designee) will notify Santen (or 
designee) and will not dispense the study medications until obtaining authorization from Santen 
(or designee). The receipt of clinical supplies form should be completed, signed, dated, and 
returned as directed. A copy must be maintained at the site for the Investigator’s records.  
The Investigator (or his/her designee) will keep a current record of the inventory, storage 
conditions and dispensing of all study medications. 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 investigational site must be accounted for and in no case will study 
medications be used in any unauthorized situation. It is the responsibility of the Investigator to 

Protocol 011710IN, Spectrum 4 Study

ASSESSMENT OF EFFICACY 
11.1. 
Efficacy Parameter 
The IOP (mmHg) measured in the study eye (identified at the baseline visit) is the efficacy 
measure for this study. The IOP at each scheduled time point (08:00, 10:00 and 16:00) will be 
evaluated at each post-baseline visit. Besides observed IOP measurements, change and percent 
change from baseline in IOP at each scheduled time point as well as the change and percent 
change from baseline in mean diurnal IOP will also be derived and evaluated.

ASSESSMENT OF SAFETY 
12.1. 
Adverse Events and Serious Adverse Events 
12.1.1. 
Definition of Adverse Events 
An adverse event (AE) is any untoward medical occurrence in a clinical trial subject. An AE 
does not necessarily have a causal relationship with the study medication. For this study, the 
investigational products are DE-117, DE-117 vehicle and Timolol. Regardless of relationship to 
the study medication, an AE can be a clinically relevant unintended sign (including an abnormal 
laboratory finding), symptom, or disease.  
Any significant change in a subject’s condition from the time that written informed consent is 
obtained, regardless of causality, is to be considered an AE. A clinically significant worsening in 
severity, intensity, or frequency of a pre-existing condition may indicate an AE. 
An elective surgical procedure scheduled or planned prior to study entry that does not require an 
overnight hospitalization is not considered an AE, and the underlying diagnosis for the procedure 
should be captured in the medical history as a pre-existing condition. The surgical procedure 
should also include the term “elective” in all reports. An elective or planned hospitalization must 
be reported as an SAE. 
The lack of efficacy of the study medication for the condition being investigated is not 
considered an AE unless a clinically significant change is assessed by the Investigator. 
12.1.1.1. Assessment of Adverse Events 
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 events may also meet regulatory serious criteria. Refer to 
definitions and reporting of serious adverse events (SAEs) in Section 12.1.2. 
An Investigator who is medically qualified must make the determination of relationship (related 
or not related) to the investigational product for each AE or SAE. When determining relationship 
to study medication, the Investigator will consider any investigational products that a subject 
could be exposed to in this clinical trial. The Investigator should decide whether there is a 
reasonable possibility that the study medication caused the event, taking into account the 
following: a) evidence b) science-based rationale c) medical and clinical judgment d) 

Protocol 011710IN, Spectrum 4 Study 
DE-117 Ophthalmic Solution 
Version 1.1 13JULY2018 
Confidential 
Page 62 of 103 
mechanisms of action e) biologic plausibility f) confounding risk factors (i.e., medical history, 
concomitant medications) g) temporal relationship h) dechallenge/rechallenge and i) lack of 
alternative explanation. 
 The event may be recorded as Related to investigational product if: 
 There is a plausible temporal relationship between the onset of the AE and 
administration of the study medication 
 The AE abates or resolves upon discontinuation of the study medication or dose 
reduction and, if applicable, reappears upon rechallenge 
 The AE cannot be readily explained by the subject’s clinical state, intercurrent 
illness, or concomitant therapies  
 The AE follows a known pattern of response to the investigational product 
 Reporting the event as Not Related to study medication may be considered if: 
 There is good evidence that the AE has an etiology other than the investigational 
product (e.g., pre-existing medical condition, underlying disease, intercurrent 
illness, or concomitant medication) 
 The AE has no plausible temporal relationship to administration of the 
investigational product (e.g., cancer diagnosed 2 days after first dose of study 
medication) 
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 electronic case report 
form (eCRF). Each recorded AE will be described by its duration (represented in dates), affected 
eye(s) (if applicable), maximum severity of the AE, seriousness criteria, suspected relationship to 
the study medication, actions taken with the study medication and the study participation, 
outcome of the AE, and any other attributable causes of the AE. 
Regardless of relationship to the clinical study, AEs that occur at any time after the subject has 
provided written informed consent until subject withdrawal or the scheduled exit visit, must be 
recorded. To improve the quality and precision of acquired AE data, 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). 

Protocol 011710IN, Spectrum 4 Study 
DE-117 Ophthalmic Solution 
Version 1.1 13JULY2018 
Confidential 
Page 63 of 103 
 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 
(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 
12.1.2.1. Assessment of Serious Adverse Events 
An AE is considered serious if it fulfills one or more of the following criteria: 
 Death (i.e., the AE caused or led to death). 
 It was life threatening (i.e., immediately life-threatening). 
 It required or prolonged inpatient hospitalization. 
 It resulted in a persistent or significant disability/incapacity (i.e., the AE resulted in a 
substantial disruption of the subject’s ability to carry out normal life functions). 

Protocol 011710IN, Spectrum 4 Study 
DE-117 Ophthalmic Solution 
Version 1.1 13JULY2018 
Confidential 
Page 64 of 103 
 It resulted in a congenital anomaly/birth defect in the offspring of a study subject who 
was exposed to study therapy prior to conception or during pregnancy. 
 It is a medically significant event(s), which may include “sight-threatening events,” 
that may not meet any of the above serious criteria but may jeopardize the subject or 
require medical or surgical intervention to prevent one of the outcomes listed above. 
12.1.2.2. Reporting Serious Adverse Events 
The SAE eCRF must be completed with as much information as is available within 24 hours of 
knowledge of the event. 
To improve the quality and precision of acquired SAE data, 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 the 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. 
Depending on the nature and seriousness of the AE, Santen may request additional 
documentation, for example, copies of the ophthalmic and medical records as well as results of 
laboratory tests. If the subject was hospitalized, a copy of the discharge summary may be 
requested. 
12.1.2.3. Expedited Reporting of Serious Adverse Events 
Santen (or designee) will provide the Principal Investigator with a reporting cover letter and a 
masked expedited safety report for expedited reporting of SAEs to the IRB or IEC. 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 
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:  
 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 4 weeks for female subjects of 
childbearing potential and 12 weeks for male subjects capable of fathering 
children after the completion of the study. Any pregnancy occurring during study 
treatment should be reported and the subject will be discontinued from the study. 
The subject should be followed until the end of pregnancy or until the end of the 
study, whichever is longer. 

Protocol 011710IN, Spectrum 4 Study 
DE-117 Ophthalmic Solution 
Version 1.1 13JULY2018 
Confidential 
Page 65 of 103 
 Medication administration errors 
 Study medication administration errors determined to be significant by the 
Investigator will be reported and evaluated as ESIs. Examples of study medication 
administration errors may include, but are not limited to: incorrect dose of study 
medication and administration of study medication from an incorrect kit. An AE 
does not necessarily need to have occurred to count as a study medication 
administration error. A medication administration error is an unintended failure in 
the process of treatment with a medicinal product that leads to, or has the 
potential to lead to harm of the subject. 
 Macular edema (including cystoid macular edema):  
 Macular edema has been reported in some patients during the DE-117 clinical 
trials. Any cases of macular edema (including cystoid macular edema) should be 
reported in the ESI form in eCRF, or in case the EDC system is down, in the 
manual ESI form. Any cases of macular edema (including cystoid macular 
edema) will need to be followed until the event is determined to be resolved, 
irreversible, chronic, stable, the subject withdraws consent, or no further 
information can be reasonably obtained as per Section 12.1.4. 
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 issued after study medication treatment 
 On-going ESIs, including pregnancy, medication errors resulting in AE’s, and 
macular edema/cystoid macular edema issued after study medication treatment 
 Early termination and withdrawal from the study due to study medication related AEs 
In addition, on a case by case basis, Santen (or designee) may request follow up beyond the 
scheduled exit visit. 
The follow-up information on an individual SAE or AE (or ESI) will be entered into the eCRF 
prior to database lock. If the information requested by Santen is not part of the eCRF, or when 
database lock has already been completed, the site’s response to follow-up requests should be 
emailed to globalPVAmericas@santen.com or reported in writing and fax to +1-415-276-5882 
(in the US).  
12.1.5. 
Manual Back-Up Reporting Procedures 
This study is utilizing an EDC system for data entry. In the event that the EDC system is 
unavailable for electronic reporting, the manual back-up reporting procedures below should be 
followed. 
 Complete an AE Form, SAE Form, pregnancy Form, medication error Form, or ESI 
Form as appropriate.

When the EDC system becomes available, the EDC system should be updated with all 
previously reported information. 
12.2. 
Safety Parameters 
In addition to observed values, changes from baseline will be evaluated at relevant post baseline 
visits. For a safety outcome measure, the baseline value will be the last observation of that 
outcome measure prior to the first dose of study medication. 
12.2.1. 
Ocular Assessments 
Ocular assessments include: 
 BCVA 
 Slit-lamp biomicroscopy findings: anterior chamber cells, anterior chamber flare, lid 
hyperemia, lid edema, conjunctival hyperemia, conjunctival chemosis, corneal 
edema, corneal staining, keratic precipitate, lens, anterior synechiae of iris and 
posterior synechiae of iris

STATISTICAL METHODS 
This section outlines topics related to the statistical methods used in the design and analysis of 
the study. A more detailed description of all the analyses and methods is provided in the 
Statistical Analysis Plan (SAP). 
14.1. 
Interim Analysis 
There is no planned interim analysis for this study. 
14.2. 
Final Analysis 
An unmasked final analysis will be performed after all subjects completed Month 3. The analysis 
will evaluate the efficacy and safety of DE-117 Ophthalmic Solution 0.002% once daily 
compared with Timolol Maleate Ophthalmic Solution 0.5% twice daily. 
14.3. 
General Considerations 
Descriptive statistics, unless otherwise noted, will include the number of subjects (N), mean, 
standard deviation (SD), median, minimum, and maximum for continuous variables and N and 
percent for categorical variables. 
The study eye will be defined as the eye that qualifies per inclusion criteria at Baseline (Visit 2). 
For example, IOP must be ≥ 22 mmHg at all IOP measurement time-points (08:00, 10:00 and 
16:00). See Section 8.1 and Section 8.2 for all inclusion/exclusion criteria. If both eyes qualify, 
the eye with the higher mean diurnal IOP at Baseline (Visit 2) will be the study eye. If both eyes 
have the same mean diurnal IOP at baseline, then the right eye will be designated as the study 
eye. 
Statistical analyses for pediatric subjects may be performed separately depending on the number 
of pediatric subjects enrolled in this study. 
More details on the statistical methods will be described in SAP which will be finalized prior to 
unmasking the data. 
14.3.1. 
Sample Size 
The sample size calculation was based on a two-sided Type I error rate of 5% and a non-
inferiority margin of 1.5 mmHg. Assuming a between-treatment difference of 0 mmHg, SD of 
4.0 mmHg and a correlation coefficient of 0.6 among repeated measures, approximately 400 
adult subjects in total (200 subjects per treatment arm) will provide 90% power to demonstrate 
non-inferiority of DE-117 Ophthalmic Solution 0.002% to Timolol Maleate Ophthalmic Solution 
0.5%. 
14.3.2. 
Statistical Hypotheses and Level of Significance 
The primary efficacy endpoint is the IOP in the study eye measured at the specified time points: 
08:00, 10:00 and 16:00 at Week 1, Week 6 and Month 3 visits. 

Protocol 011710IN, Spectrum 4 Study 
DE-117 Ophthalmic Solution 
Version 1.1 13JULY2018 
Confidential 
Page 69 of 103 
For the primary endpoint, a Mixed Effect Model for Repeated Measurement (MMRM) will be 
used to test the following hypotheses: 
H0: µT – µC > Δ versus HA: µT – µC ≤ Δ  
where µT and µC denote the mean values of the primary endpoint in DE-117/Vehicle arm and 
Timolol Maleate arm, respectively, and Δ denotes the non-inferiority margin of 1.5 mmHg.  
Treatment difference between the DE-117/Vehicle arm and Timolol Maleate arm at each 
specified time point of each post-baseline visit up to Month 3 will be reported along with 95% 
confidence intervals. Non-inferiority is established if the upper limit of the two-sided 95% 
confidence interval for the difference in the mean IOP (0.002% DE-117 - Timolol Maleate) is  
≤ 1.5 mmHg at all nine time points and ≤ 1.0 mmHg in majority (5 or more) of the time points.  
If the upper limit of the 95% confidence interval for the difference is ≤ 0 at all nine time points, 
superiority of DE-117 to Timolol will be claimed.  
If non-inferiority in the primary endpoint is achieved, then the following two key secondary 
endpoints will be tested sequentially according to hierarchical fixed sequence procedure:  
1. Mean diurnal IOP in the study eye at Month 3 
The corresponding hypothesis is: 
H0S1: µTs1 – µCs1  > Δ versus HAS1: µTs1– µCs1 ≤  Δ 
where µTs1 and µCs1 denote the mean diurnal IOP at Month 3 in DE-117/Vehicle arm and Timolol 
Maleate arm, respectively; and Δ denotes the non-inferiority margin of 1.5 mmHg.   
If the hypothesis is rejected at 0.05 significance level, then the following key secondary endpoint 
will be tested: 
2. Mean diurnal IOP in the study eye at Week 1 
The corresponding hypothesis is: 
H0S2: µTs2  = µCs2  versus HAS2: µTs2 ≠ µCs2 
Where µTs2 and µCs2 denote the mean diurnal IOP at Week 1 in DE-117/Vehicle arm and Timolol 
Maleate arm, respectively.  
14.4. 
Study Populations 
14.4.1. 
Safety Population 
The Safety Population will include all randomized subjects who received at least one dose of the 
study medication. The safety analysis will be performed on the Safety Population by actual 
treatment received. 
14.4.2. 
Full Analysis Set 
The Full Analysis Set (FAS) will include all randomized subjects who received at least one dose 
of study medication and provided at least one post-baseline IOP measurement. The efficacy 
analysis will be performed on the FAS or a subset of the FAS by planned treatment. 

Protocol 011710IN, Spectrum 4 Study 
DE-117 Ophthalmic Solution 
Version 1.1 13JULY2018 
Confidential 
Page 70 of 103 
14.4.3. 
Per-Protocol Set 
The Per-Protocol Set (PPS) is a subset of the FAS, restricted to the subjects who fulfill the 
protocol in the terms of the eligibility, interventions, and outcome assessment. It will be the 
analysis population for some sensitivity analyses. More details will be provided in SAP. 
14.5. 
Handling of Missing Values 
The primary analysis of continuous IOP endpoints will be performed using the MMRM analysis 
on observed cases. As sensitivity analyses, a last-observation-carried-forward (LOCF) approach 
and a Pattern Mixture Models (PMM) approach may be applied to evaluate the impact of missing 
data on the primary analysis results. For the binary IOP endpoints, the missing data at Month 3 
will be imputed using an LOCF approach. 
For medical events including AEs and medical history, completely or partially missing onset and 
resolution dates will be imputed in a conservative fashion. Same rules will be followed to impute 
the completely or partially missing start and end dates of non-study medications. 
Unless specified otherwise, descriptive summaries will be based on observed cases.  
More details on handling of missing data will be provided in the SAP. 
14.6. 
Demographic and Baseline Characteristics 
Age, sex, race, ethnicity, iris color, and baseline IOP will be summarized with descriptive 
statistics by treatment. 
Concurrent diseases will be coded using the latest version of Medical Dictionary for Regulatory 
Activities (MedDRA). Subjects with any concurrent diseases will be tabulated by primary 
System Organ Class (SOC) and Preferred Term (PT) specified in the MedDRA. 
Subjects using any prior medications that has been used for glaucoma or OHT within 28 days 
before Screening (Visit 1) will be tabulated by Anatomical Therapeutic Chemical (ATC) levels 
and PT specified in the latest version of World Health Organization Drug Dictionary Enhanced 
(Organization, 2011). 
14.7. 
Efficacy Analyses  
Unless specified otherwise, for subjects who discontinue from the study medication per protocol 
before the Study Exit, the IOP data collected after the study medication discontinuation with any 
use of non-study IOP lowering medication or surgery will be censored from all efficacy analyses. 
14.7.1. 
Analysis of Primary Efficacy Endpoint  
The primary efficacy endpoint is the IOP in the study eye measured at the specified time points: 
08:00, 10:00 and 16:00 at Week 1, Week 6 and Month 3 (Visits 3, 4 and 5). 
A MMRM will be carried out on observed cases up to Month 3. At each scheduled time point of 
each visit, least square mean IOP of each treatment arm and 95% confidence interval for the 
difference in least square means between DE-117/Vehicle and Timolol Maleate will be 
estimated. Non-inferiority is established if the upper limit of the 95% confidence interval for the 

Protocol 011710IN, Spectrum 4 Study 
DE-117 Ophthalmic Solution 
Version 1.1 13JULY2018 
Confidential 
Page 71 of 103 
difference is ≤ 1.5 mmHg for all nine time points and ≤ 1.0 mmHg for at least 5 out of the 9 time 
points.  
The primary analysis will be based on the FAS. The same analysis will be repeated on the PPS 
population as a sensitivity analysis. More details on the model specifications will be provided in 
the SAP. 
14.7.2. 
Analysis of Secondary Efficacy Endpoints 
14.7.2.1. Key Secondary Efficacy Endpoints 
The key secondary efficacy endpoints are 
 Mean diurnal IOP in the study eye at Month 3 (Visit 5), and 
 Mean diurnal IOP in the study eye at Week 1 (Visit 3) 
A MMRM will be carried out on observed cases up to Month 3. The least square mean diurnal 
IOP of each treatment arm and 95% confidence interval for the difference in least square means 
between DE-117/Vehicle and Timolol Maleate at Week 1 and Month 3 will be estimated, 
respectively. If non-inferiority in the primary endpoint is achieved, then the two key secondary 
endpoints will be tested sequentially at the 0.05 significance level (2-sided) to control the overall 
Type I error rate associated with the two comparisons. 
The primary analysis will be based on the FAS. The same analysis will be repeated on the PPS 
population as a sensitivity analysis. More details on the model specifications and multiplicity 
adjustment will be provided in the SAP. 
14.7.2.2. Other Secondary Efficacy Endpoints 
Other secondary endpoints to be assessed include: 
 Change and percent change from baseline in IOP at each timepoint/post-baseline visit 
 Change and percent change from baseline in mean diurnal IOP at each post-baseline  
visit 
 Having a mean diurnal IOP reduction ≥ 20%, ≥ 25%, or ≥ 30% from Baseline  
(Visit 2) at each post-baseline visit 
 Having a mean diurnal IOP ≤ 18mmHg at each post-baseline visit 
The Continuous secondary endpoints will be analyzed using MMRM on observed cases. More 
details on the model specifications will be provided in the SAP. 
The binary secondary endpoints will be analyzed using the Pearson’s chi-square test for a 2×2 
contingency table. The Fisher’s Exact test may be conducted as a sensitivity analysis. 
Subgroup analyses may be performed for secondary endpoints using descriptive statistics. 
14.8. 
Safety Analyses 
All safety outcome measures will be summarized descriptively for the Safety Population. The 
safety outcome measures include AEs, blood pressure and pulse rate, BCVA, slit-lamp 
biomicroscopy findings, ophthalmoscopy, iris color, eyelash, and eyelid.

AEs will be coded using the latest version of Medical Dictionary for Regulatory Activities 
(MedDRA). Subjects with any AEs will be tabulated by primary SOC and PT specified in the 
MedDRA. Similarly, subjects with any ocular and non-ocular AEs will be tabulated separately. 
AEs, ocular and non-ocular will also be summarized by relationship to treatment and maximum 
severity. In addition, SAEs and discontinuations due to AEs will be summarized. 
Safety parameters listed in Section 12.2.1 and Section 12.2.2 will be summarized using 
descriptive statistics by actual treatment received. Changes from baseline in these safety 
parameters will also be summarized by treatment.

Ethics Review 
The final study protocol and the final version of the informed consent form (ICF), for the main 
study and the ICF for the pharmacogenomics study, assent form and other study related material, 
as appropriate, must be approved in writing by an IRB or IEC as appropriate. If an IRB or IEC 
does not approve the collection of blood samples for optional future pharmacogenomic research, 
this will not affect the approvals for conducting the main study. The Principal Investigator must 
submit written IRB or IEC approval to Santen (or designee) before study initiation. Refer to 
Section 21.1, Appendix A for a list of obligations of Investigators. 
The Principal Investigator is responsible for informing the IRB or IEC of any amendment to the 
protocol in accordance with local regulations and guidelines. In addition, the IRB or IEC must 
approve all advertising used to recruit subjects for the study. The protocol must be re-approved 
by the IRB or IEC upon receipt of amendments. 
The Principal Investigator is also responsible for providing the IRB or IEC with progress reports 
and notifications of any reportable serious adverse drug reactions from the investigational 
product. 
17.2. 
Ethical Conduct of the Study 
This study will be conducted in compliance with IRB or IEC, and regulatory requirements. This 
study will also be conducted in compliance with the protocol, GCP guidelines, International ICH 
guidelines, and the Declaration of Helsinki. 
17.3. 
Written Informed Consent 
The Principal Investigator at each center will ensure that the subject is given full and adequate 
oral and written information about the nature, purpose, possible risk and possible benefit of the 
study and participation in the collection of blood samples for future pharmacogenomic research 
studies. If the subject does not wish to provide a blood sample for the biomarker research study 
that it will not affect the subject’s enrollment in this clinical trial. Subjects must also be notified 
that they are free to withdraw from either study at any time. Subjects should be given the 
opportunity to ask questions and allowed time to consider the information provided. Before 
participating in any study-related activity, voluntary informed consent must be documented by 
the use of a written ICF approved by the IRB or IEC and signed and dated by the subject or the 
subject’s legally authorized representative at the time of consent. The original signed and dated 
ICF will be retained with the study records, and a copy of the signed ICF will be given to the 
subject or the subject’s legally authorized representative. See Section 21.2, Appendix B. 
For the pediatric subjects, written informed consent must be signed in accordance with 
local regulatory and legal requirements by the patient or parent/legal guardian, and giving 
of assent by the patient if appropriate, must be documented prior to initiation of any study-
related procedures. Subjects and their parents/legal guardians must be provided with 
adequate time to think over their possible participation in the study, to ask questions from 
the investigator and/or to discuss the study participation with their family or primary care

DATA HANDLING AND RECORDKEEPING 
18.1. 
Inspection of Records 
The Principal Investigator will allow Santen (or designee), the governing IRB or IEC and 
applicable regulatory agencies to inspect any aspect of the study, including all study records, 
eCRFs, and corresponding portions of the subject’s charts and medical records at any time 
during the study. The purpose of these inspections is to verify adherence to the protocol, 
completeness and accuracy of the eCRF data, and compliance with ICH-GCP guidelines and 
applicable regulatory requirements. 
18.2.

18.2.2. 
Source Data 
Source data is defined as all information in original records and certified copies of original 
records of clinical findings, observations, or other activities in a clinical trial necessary for the 
reconstruction and evaluation of the trial. Source data should be accurate, legible, 
contemporaneous, original, attributable, complete and consistent. Source data is documented in 
source documents which may be both electronic and on paper. 
The Investigator(s) should be aware about the location of the source data and consistent in 
recording them. The intended location should be clearly defined prior to subject enrollment. One 
way of achieving this is to generate a source data location list. The source data location list will 
be prepared by the site and will be signed and dated by the Principal Investigator. The list will be 
filed in the Investigator’s trial master file. 
18.2.3. 
Data Collection 
The Principal Investigator must maintain detailed records on all subjects who provide informed 
consent. Data for screened and randomized subjects will be entered into eCRFs. eCRFs should 
be completed within 3 business days of each subject visit as much as possible. Review of the 
eCRFs will be completed remotely by Santen (or designee). At designated intervals, a study 
monitor will perform Source Data Verification on site. During those visits, Santen (or designee) 
will monitor the subject data recorded in the eCRF against source documents at the study site. 
Santen (or designee) will review and evaluate eCRF data and use standard system edits, and may 
use centralized monitoring evaluations, to detect errors in data collection. At the end of the study, 
a copy of the completed eCRFs will be sent to the site to be maintained as study records.

for pediatric subjects is shown in Section 21.4.  
21.3.1. 
Demographics, Medication/Therapy and Medical History 
Demographics including age, sex, race, prostaglandin analogs naïve status, and ethnicity will be 
obtained through subject interviews at Visit 1 (Screening). 
Medications and procedures/therapies will be confirmed through subject interviews during the 
study. 
Following details of prior medication that has been used for glaucoma or OHT within 28 days 
before the date of Visit 1, or any concomitant medication, must be recorded in the subject’s 
source documents. 
 Name of medication, route of administration, treated eye(s) (if applicable), dose, 
frequency, indication, start date and stop date 
Following details of prior procedure/therapy that has been received for glaucoma or OHT within 
28 days before the date of Visit 1, or any concomitant procedure/therapy, must be recorded in the 
subject’s source documents. 
 Name of procedure/therapy, treated eye(s) (if applicable), indication, start date and 
stop date 
Medical history including all lifetime ocular medical history to the extent possible, non-ocular 
medical history within 5 years, diagnosis, ocular surgical history, current ocular and systemic 
conditions will be confirmed through subject interviews at Visit 1 (Screening) to determine if the 
subject meets eligibility criteria. Primary diagnosis and the affected eye must be recorded in the 
subject’s source documents. 
 Name of concurrent disease and affected eye(s) (if applicable) will be confirmed at 
Visit 1 (Screening) and Visit 2 (Baseline), and recorded in the subject’s source 
documents. 
21.3.2. 
Pregnancy Test 
A urine pregnancy test will be conducted using a commercially available test kit at Visit 1 
(Screening), Visit 2 (Baseline), and Visit 5 Study Exit/Early Termination for all females of 
childbearing potential. A female is considered of childbearing potential unless she is post-
menopausal (at least 12 months since last menses occurred), is without a uterus or without both 
ovaries, or has had a bilateral tubal ligation. To perform the pregnancy test, follow instructions 
provided by the manufacturer of the urine pregnancy test kit. 
21.3.3. 
Vital signs (Blood pressure/Pulse rate) 
Systolic blood pressure, diastolic blood pressure, and pulse rate will be measured at Visit 1 
(Screening), Visit 2 (Baseline) and Visit 5 Study Exit/Early Termination. Vital signs (resting 
blood pressure and pulse rate) will be collected anytime at Visit 1 (Screening), and 
approximately 08:00 for Visit 2 (Baseline), and Visit 5 before the morning dose.

Page 89 of 103 
Vital signs will be collected in a sitting position after keeping quiet for more than 5 minutes.  
21.3.4.
Iris color, Eyelash, Eyelid  
Please take photographs of the iris, eyelids and eyelashes of each eye at Visit 2 (Baseline), and 
Visit 5 Study Exit/Early Termination. Six (6) photos are required at each visit as follows:   
The photographs taken at Visit 2 (Baseline) will be used to help the Investigator assess iris color 
(e.g., brown, yellow-brown, green-brown, green with slightly brown, green, blue/gray-brown, 
blue/gray with slightly brown, blue/gray) and any changes from baseline (decreased/no 
change/increased) in iris color, eyelashes and eyelids at Visit 5 Study Exit/Early Termination. 
For any changes from baseline in deepening of the upper eyelid sulcus (DUES), the response will 
be YES or NO. 
Each photograph will be labeled with subject number, OD or OS, and Visit number, and kept 
with the subject’s source document. 
21.3.4.1. Iris Color 
The Investigator will assess the iris color and any change (e.g., pigmentation) at Visit 5 
Exit/Early Termination using the photographs obtained at Visit 2 (Baseline). 
21.3.4.2. Eyelash 
The Investigator will assess eyelash change at Visit 5 Study Exit/Early Termination (e.g., length, 
thickness, pigmentation and number) using the photographs obtained at Visit 2 (Baseline). 
21.3.4.3. Eyelid 
The Investigator will assess eyelid change at Visit 5 Study Exit/Early Termination (e.g., 
pigmentation, hair growth and deepening of the upper eyelid sulcus) using the photographs 
obtained at Visit 2 (Baseline). For any changes from baseline in deepening of the upper eyelid 
sulcus (DUES), the response will be YES or NO.

21.3.5. 
Refraction 
Refraction will be performed for each eye at Visit 1 (Screening). At Visits 2 to 5, if more than 10 
letters in BCVA were lost compared to the screening visit, then refraction should be performed. 
21.3.6. 
Best-Corrected Visual Acuity 
BCVA (Best-Corrected Visual Acuity) will be measured for each eye prior to the 08:00 IOP 
measurement at all visits except Visit 1/1a (Screening or mid washout visit) under normal room 
illumination using visual acuity chart (ETDRS chart) and the logMAR scoring will be recorded 
in the subject’s source document. For Visit 1/1a, the corrected visual acuity should be performed 
prior to IOP measurement. If ETDRS chart is used, the following procedure should be followed. 
21.3.6.1. ETDRS Visual Acuity Scoring 
The Examiner records each letter identified correctly by circling the corresponding letter on an 
appropriate visual acuity worksheet. The Examiner records a letter read incorrectly, or a letter for 
which the subject made no guess, by crossing the letter out with an “x” or a line. Each letter read 
incorrectly is scored as one point. The last line in which a letter is read correctly will be taken as 
the Base logMAR line. 
The total number of letters that have an “x” or a line through them (letters read incorrectly or not 
at all) down to and including the Base logMAR line, and multiply the total number by 0.02. Add 
this value to the Base logMAR value to obtain the logMAR score. 
Example: 
Subject correctly reads 4 of 5 letters on the +0.2 line, and 2 of 5 letters on the +0.1 line, and 
zero letters on the 0.0 line 
Base logMAR value = +0.1 (last line in which a letter was read correctly) 
Total number of letters missed = 4 (number of letters missed on the +0.2 line plus the number 
missed on the +0.1 line) 
LogMAR score = +0.1 + (4 x 0.02) = 0.18

21.3.8. 
Intraocular Pressure 
IOP will be performed at each visit. At visit 1/1a, IOP can be measured at any time. For Visit 2 
to Visit 5 Study Exit/Early Termination, IOP measurements will be scheduled for 08:00 
(±60min), 10:00 (±60min) and 16:00 (±60min). 
IOP will be measured using calibrated manual Goldmann applanation tonometer. Measurement 
will be performed preferably by the same Investigator (operator) and the same authorized study 
staff (recorder) throughout the study. Investigator (operator) who performs the IOP measurement 
must have at least 2 years of experience in IOP measurement.

Version 1.1 13JULY2018

Page 94 of 103 
The right eye is always tested first. At least two, and sometimes three, consecutive measurements 
are made to obtain a determination of IOP. Each IOP measurement and the clock time of IOP 
measurement will be recorded in the subject’s source document. 
A single measurement is made as follows: 
 The Investigator adjusts the force on the tonometer dial to an initial setting 
corresponding to 10 mmHg. The slit-lamp magnification is set at 10X. The light 
source is positioned at an angle of approximately 45º, and the aperture is maximally 
opened. A cobalt blue filter is employed. 
 After instillation of a topical anesthetic, a fluorescein paper strip is placed near the 
lateral canthus in the lower conjunctival sac. Once the lacrimal fluid is sufficiently 
colored, the paper strip is removed. Alternatively, one drop of premixed fluorescein 
and anesthetic (Fluress, Barnes Hind) may be instilled. The Investigator should use 
the same technique each time, be it a paper strip or a pre-mixed eye drop. 
 The subject and slit-lamp are adjusted so that the subject’s head is firmly positioned 
on the chin rest and against the forehead rest without leaning forward or straining. 
Tight-fitting neckwear is loosened. The subject is asked to look straight ahead at a 
distant object or fixation target. If it is necessary to hold the eyelids open, the 
Investigator holds the eyelids against the orbit rim, taking care not to apply any 
pressure to the globe. The subject is cautioned not to hold his breath. 
 The Investigator looks through the slit-lamp and gently brings the tip of the prism into 
contact with the center of the cornea. The mires are well-focused, centered 
horizontally, and positioned vertically so that they are of equal circumference above 
and below the horizontal dividing line. If the mires are narrower than approximately 
1/10 their diameter, additional fluorescein is instilled. 
 The Investigator adjusts the measuring drum until the inner borders of the two mires 
just touch each other or, if pulsation is present, until the mires separate a given 
distance during systole and overlap the same distance during diastole. 
 The Investigator removes the tip from the cornea, and the authorized study staff 
(recorder) records the reading on the dial, rounded to the next highest integer. For 
example, if the measurement indicated is between 16 and 17, then 17 is recorded as 
the measurement in the subject’s source document. 
 The Investigator may be recorder instead of the authorized study staff, if he/she is 
not assigned. 
 If corneal astigmatism is greater than 3.0 D, the prism is rotated so that the red line 
corresponds to the orientation of the longer axis of the elliptical applanated area. 
The above procedure is then repeated for the same eye, and that second measurement is also 
recorded in the subject’s source document. 
 If the two measurements differ by less than 3 mmHg, then the average of the two 
measurements becomes the recorded IOP. For example, if the two measurements are 
22 and 23, then 22.5 is the final recorded IOP.

Version 1.1 13JULY2018

Page 95 of 103 
 However, if the two measurements differ by 3 mmHg or more, then a third 
measurement is made, and the median of the three measurements becomes the 
recorded IOP (the median is the middle measurement after ordering the 
measurements from low to high). For example, if the three measurements are 15, 19, 
and 16, then 16 is the final recorded IOP. 
The IOP in the left eye is then measured using the same technique. 
21.3.8.1. Goldmann Applanation Tonometer Calibration 
Every tonometer being used in the study must be calibrated for accuracy before the first subject 
undergoes screening (mandatory), and then check calibration monthly until the last subject has 
exited the study. For checking calibration, follow the manufacturer’s instructions. If the variation 
is within ±2 mmHg, the tonometer is considered adequately calibrated. However, if the variation 
exceeds this amount, the tonometer should be sent for repair and a different, adequately 
calibrated instrument should be used for IOP measurement. The date of each calibration, along 
with the name and signature (or initials) of the person who performed the calibration, will be 
documented. The tonometer calibration record will be retained as a part of the study record. 
21.3.9. 
Pachymetry (Central Corneal Thickness) 
The central corneal thickness (µm) of each eye using any pachymeter including optical 
pachymeter, ultrasound pachymeter, OCT (optical coherence tomography) etc. will be measured 
and recorded after IOP measurement at Visit 1 (Screening). Pachymetry should be performed 
after IOP measurement. The same pachymeter should be used during the course of the study. 
21.3.10. 
Gonioscopy 
Gonioscopy will be performed to examine the angle of the anterior chamber after IOP 
measurement at Visit 1 (Screening), if it has not been performed within 3 months (90 days). The 
Shaffer scale will be used to rate the degree of angle closure. 
(0) = approximately 5 degrees or less, complete or partial closure 
(1) = approximately 10 degrees 
(2) = approximately 20 degrees 
(3) = approximately 30 degrees 
(4) = approximately 40 degrees or more 
21.3.11. 
Visual Field 
Visual field examinations will be performed using a static or dynamic perimeter (Humphrey or 
Octopus) without pupil dilation at Visit 1 (Screening), if it has not been performed within 3 
months (90 days) or the previous visual field test(s) indicates low subject reliability (e.g., due to 
fixation losses, false positive errors, or false negative errors). Glaucomatous visual field loss will 
be evaluated by the Investigator as presence or absence (mean deviation, pattern SD, glaucoma 
hemifield test, and type of glaucomatous visual field loss).

Page 96 of 103 
Visual field tests that, in the Investigator's opinion, indicate low subject reliability (e.g., due to 
fixation losses, false positive errors, or false negative errors) should be excluded. A copy of the 
computer printout from the visual field test(s) will be attached to the subject’s source documents. 
21.3.12. 
Ophthalmoscopy (Fundus) Examination 
The ophthalmoscopy (fundus) examination will be performed for each eye at Visit 1, Visit 2, and 
Visit 5 Study Exit/Early Termination, and graded as described below. The examination will be 
performed with pupil dilated at Visit 1 and Visit 5/Study Exit. Please dilate pupil and perform 
after all other ocular procedures have been completed. Cup to disc ratio and abnormality in 
retina, macula, choroid, and vitreous will also be evaluated. 
Glaucomatous Optic Nerve Findings 
The optic nerve will be evaluated using a 4-point scale (0-3 scale). 
None 
(0) = No damage 
Mild 
(1) = Optic nerve damage, secondary to glaucoma including any rim loss 
(sloping or thinning) 
Moderate (2) = Optic nerve damage, including cupping to disc margin at one or more 
points 
Severe 
(3) = Optic nerve damage, nearly total cupping, only nasal rim or less present 
21.3.13. 
Blood Sample for Pharmacogenomics/genomics Study 
At sites which elect to participate and for subjects who agree to provide a blood sample, an 
exploratory biomarker laboratory research study will be performed to evaluate the association of 
possible genetic biomarkers with the study drug(s) and/or ophthalmologic conditions. 
Approximately 10 mL of blood will be collected for genetic analysis from the subject and stored 
in a refrigerator until shipment. Please refer to the separate procedure manual for sample 
handling, storage, and shipment. The samples will be coded to protect the participants’ private 
information. Nucleic acids will be extracted from blood sample and stored in the repository for 
future pharmacogenomics/genomics studies performed by appropriate assay platforms such as 
PCR (Polymerase Chain Reaction), hybridization, and sequencing on the genes involved in the 
study drug(s) and/or ophthalmologic conditions. Individual subjects’ results from the research 
testing on their samples will not be communicated to them. 
Samples collected and stored, and relevant documents (the list of screening/registration of 
subjects only for documents to be retained by the medical institution) will be retained for the 
period agreed in the IC. Upon completion of analyses or the retention period, they will be 
anonymized and discarded. If the subject withdraws the consent, samples will be immediately 
disposed, and the applicable subject will be informed in writing. 
For any other matters not specified in the protocol, a written procedure will be defined 
separately.

Measurement for Pediatric Subjects  
Distance Visual Acuity Assessment for Pediatric Subjects (Pediatric Ophthalmology and 
Strabismus, 2017-2018 Basic and Clinical Science Course, AAO) 
Visual acuity assessment requires different eye charts or approaches depending on the age and 
cooperativeness of the child. The cognitively highest test type that the child is capable of 
performing should be used. The following age-appropriate eye charts or methods used for visual 
acuity testing serve as a guide only.  
 

The same type of eye chart or vision test and lighting conditions (e.g., room 
illumination) should be used throughout the course of the study.  

A child who has corrective glasses should be tested wearing them. The used 
refraction should also be recorded.  

In subjects who could not be tested using the manufacturer’s recommended test 
distance, the actual test distance should be recorded in the eCRF.

Intraocular Pressure Measurement for Pediatric Subjects 
IOP is the primary endpoint of the study. Every effort should be made to perform IOP 
measurement to have the diurnal curve. IOP will be measured with age-appropriate tonometers 
(e.g. Goldmann applanation tonometer, a Perkins tonometer, a tonopen, iCare tonometer etc.) to 
the extent the subject is able to cooperate. The same tonometer to measure IOP should be used at 
all visits for a given subject. Investigator or IOP examiner should follow the standard procedures 
used in their office to measure IOP.  
For pediatric subjects who are old enough and can sit at the slit lamp for applanation and are able 
to cooperate with the IOP measurement, Goldmann applanation tonometer is preferred. 
Otherwise, handheld tonometers, for example, Perkins applanation tonometer, iCare tonometer 
or tonopen tonometer are also acceptable. Follow the manufacturing guidance on the use of each 
handheld tonometer. For pediatric subjects who resist anesthetic eye drops, iCare tonometer can 
be tried.
