Estimated date first patient enrolled:  February 2019 
Estimated date last patient completed: Nov2022 
Phase of development:  
III 
Objectives:  
Primary: 
 To demonstrate that the intraocular pressure (IOP) reducing effect of DE-130A 
(latanoprost 50 microg/ml preservative-free eye drops emulsion) is non-inferior to that of 
Xalatan® [latanoprost 50 microg/ml Benzalkonium Chloride (BAK)-preserved eye drops

Week 12 without using any rescue medication(s). 
Secondary: 
 To compare the effect on improving Ocular Surface Disease (OSD) signs and symptoms 
between treatment groups over 3 months (Period 1). 
 To estimate the effect of DE-130A on OSD signs and symptoms improvement up to 15 
months (Periods 1 & 2). 
 To compare the efficacy on IOP reduction between treatment group  over 3 months 
(Period 1). 
 To estimate the effect of DE-130A on IOP upto 15 months (Periods 1 & 2). 
 To estimate the local ocular tolerance and systemic safety of the two treatments over 3 
months (Period 1). 
 To evaluate the local ocular tolerance and systemic safety of DE-130A up to 15 months

 5 days to 6-week washout period  
 15 months for the first 130 patients 
 12 weeks for the next 250 patients 
 
Patients will attend 6 visits following the wash-out phase (up to 6 weeks):  
 Period 1 (3-month investigator-masked treatment period, DE-130A vs Xalatan®): 
Randomisation/Baseline visit (Day 1), Week 4 (±3 days) and Week 12 (±3 days) 
 Period 2 (12-month follow-up from Week 12, open-label DE-130A treatment for the 
first 130 patients who complete their week 12 visit and agree to participate in the open-
label period of the study): Month 6 (± 7days), Month 9 (±7 days) and Month 15 (± 1 
week) visits. 
Number of patients (planned):  
Approximately 380 patients with Open-Angle Glaucoma (OAG), or ocular hypertension 
(OHT) (190 in DE-130A group and 190 in Xalatan® group) will be randomised in this study 
to obtain 173 evaluable patients per treatment group at Week 12 (assumed dropout rate of 
10%).  
A safety follow up of 12 months is planned for the first 130 patients who will attend the Week 
12 visit and agree to participate in the open-label period of the study. They will then be treated 
with DE-130A in an open-label fashion.

Study drug, dosage, mode and duration of administration:  
Study drug: DE-130A (latanoprost 50 microg/ml eye drops emulsion, SD) eye drops emulsion 
in single-dose containers. 
Regimen: Instillation of one drop, once daily in the evening (9 pm ±1 hour) in the 
conjunctival sac of the affected eye(s). Both eyes will be treated unless the patient suffers 
from unilateral OAG/OHT. 
Duration of treatment: 3 months during Period 1 (randomised, investigator-masked 
treatment) and up to 12 months during Period 2 (open-label DE-130A 12-month extension 
for the first 130 patients who complete their Week 12 visit and agree to participate in the 
open-label period of the study). 
The period 2 will be open in some countries only. 
Comparator, dosage, mode and duration of administration:  
Investigational product: Xalatan® (latanoprost 50 microg/ml eye drops solution) eye drops in 
2.5 ml dropper containers. 
Regimen: Instillation of one drop, once daily in the evening (9 pm ± 1 hour) in the 
conjunctival sac of the affected eye(s). Both eyes will be treated unless the patient suffers 
from unilateral OAG/OHT . 
Duration of treatment: 3 months during Period 1 (randomised, investigator-masked 
treatment) 
Wash-out phase therapy: 
At screening visit, prior therapies for OAG or OHT must be discontinued during a wash-out 
phase of at least 5 days and up to 6 weeks (according to the IOP lowering medications 
currently used at screening visit). Washout periods should be as follows: 
• 
Prostaglandin analogs = 4 weeks 
• 
Topical beta blockers ≥ 3 weeks and ≤ 4 weeks 
• 
Topical carbonic anhydrase inhibitors  ≥ 5 days and ≤ 4 weeks

9 
 
• 
All other IOP lowering medication ≥ 2 weeks and ≤ 4 weeks 
During this wash-out period, topical IOP-lowering medication will be replaced by 
brinzolamide* (Azopt®) one drop twice daily. Then brinzolamide will be stopped 5 days before 
randomisation (6 to 7 days if over the weekend). At baseline, if IOP is <22 mmHg, the wash-
out period can be extended and the IOP should be re-assessed two to three days after the first 
measurement. If the IOP is still < 22 mmHg at the second measurement, a third assessment 
should be performed two to three days after the second measurement. If the IOP is still < 22 
mmHg at the third  measurement, the patient cannot be randomized in the study. 
 
*Patients already receiving brinzolamide prior to screening visit will have to stop their 
treatment for a 5-day washout before randomisation (without any need to receive again the 
brinzolamide provided by the Sponsor).

• 
Quality of life (Glaucoma Quality of Life-15) scores at Baseline visit, Week 12, and 
Month 15/early termination visits. 
Safety: 
In the Safety population, at all visits and for each treatment (Period 1) and for the Open-
Label population for DE-130A at all visits (Period 2 and Periods 1 & 2 combined), safety and 
tolerability endpoints are:

The incidence and severity of ocular and systemic adverse events    
• 
Best-corrected distance visual acuity (BCDVA) 
• 
Slit lamp examination (lashes, anterior chamber and lens). 
• 
Dilated and undilated (for cup-to-disc ratio) fundoscopy. 
Statistical methods: 
Sample size 
Sample size was calculated assuming a mean difference in IOP change from baseline of 0 
mmHg and a common standard deviation of 4.26 mmHg in the peak or trough IOPs, 
respectively, for the comparison between the DE-130A and the Xalatan® (control) groups. A 
total sample size of approximately 380 subjects (190 per treatment arm) will provide 90% 
power to demonstrate the non-inferiority of the DE-130A group to the control group (one-sided 
α = 0.025) for non-inferiority margin of 1.5 mmHg, assuming 10% dropout rate. 
Randomisation 
Patients will be randomly assigned in a 1:1 ratio to receive either DE-130A (experimental) or 
Xalatan® (comparator) for 3 months. To minimize the effect of baseline OSD severity, 
randomisation will be stratified according to the CFS score at Baseline visit (CFS ≤ 1 and ≥ 2, 
modified Oxford scale). 
Study eye 
Data collection will be done on both eyes, however, efficacy analyses will only be performed 
on the study eye, which is defined as the eye that qualifies per inclusion/ exclusion criteria at 
the Baseline Visit. If both eyes are eligible, the eye with the higher IOP at the Baseline Visit 
will be chosen. If both eyes have the same IOP value, the eye with the higher CFS at the 
Baseline Visit will be chosen. If both eyes have the same IOP and CFS values, then the right 
eye will be designated as the study eye. 
Analysis Populations 
The following analysis populations are considered: 

DE-130A (latanoprost 50 microg/ml eye drops emulsion, SD) Amendment1 Version 5.0 26 February 2021 
 
Confidential 
12 
 
 The Full Analysis Set (FAS) population consists of all randomised subjects who 
received at least one dose of the study medication and provided at least one post-
baseline IOP measurement at peak and trough timepoints, separately. The FAS 
population will be the analysis population for  all efficacy endpoints in Period 1 and 
will use treatment as randomised. 
 The Safety population consists of all subjects randomized in the study who received 
at least one dose of the study medication. The Safety population will be the analysis 
population for all safety analyses in Period 1 and will use treatment as actually received. 
 The Glaucoma/OHT Per-Protocol (PP) population will be a subset of the FAS 
subjects. It includes all FAS subjects without any of the major protocol deviations that 
could affect the primary efficacy endpoint. The PP population will be used for 
sensitivity analyses of the primary efficacy endpoints in Period 1 and will use treatment 
as randomised.  
 The Ocular Surface Disease Per-Protocol (PP) population will be a subset of the FAS 
subjects. It includes all FAS subjects without any of the major protocol deviations that 
could affect the key secondary endpoints. This population will be used for sensitivity 
analyses of the key secondary endpoints in Period 1 and will use treatment as 
randomised. 
 The Open-Label Population will be a subset of the FAS subjects who complete their 
Week 12 Visit and agree to participate in the open-label period of the study, and 
received at least one dose of the study medication during the open-label period and 
provided at least one morning IOP measurement after the Week 12 Visit.This 
population will be the analysis population for the analyses of efficacy endpoints in 
Period 2 and for Periods 1 & 2 combined data and will use treatment as randomised. 
Analysis of Demographics and Baseline Characteristics 
Descriptive summaries will be performed for demographic (including age, gender, race, 
ethnicity, female patients’ menopausal status) and baseline characteristics variables 
(including time since diagnosis, past surgery or laser treatment in the study eye, and smoking 
status). They will be summarized by treatment groups for the overall FAS population, Safety 
population, Open-label population, separately.  
In addition, medical history (ocular and systemic), and prior and concomitant medication use 
will be summarized by treatment group for the overall FAS population.  
Analysis of Primary and Key Secondary Efficacy Endpoints 
The primary efficacy endpoint is the change from baseline in peak and trough IOP, 
respectively, between the DE-130A group and the Xalatan® group in the study eye at Week 
12. Statistical analysis will be performed using a  mixed-effects model for repeated measures 
(MMRM) on observed cases collected up to Week 12 based on FAS population. A separate 
MMRM model will be performed for IOP at peak and trough, respectively. The model will 
include treatment, visit, treatment-by-visit interaction and country as fixed effects, baseline 
IOP at the respective timepoint (peak or trough) as covariates. Non-inferiority will be

established if the upper limit of the one-sided 97.5% confidence intervalis less than or equal to 
the non-inferiority margin of 1.5 mmHg at both the peak and trough timepoints at Week 12. 
Superiority is achieved with respect to this endpoint if the upper limit of the one-sided 97.5% 
confidence interval is < 0 mmHg for both timepoints at Week 12.  
 
If non-inferiority in the primary endpoint is achieved, the two key secondary endpoints will be 
tested for superiority, sequentially according to hierarchical fixed procedure. MMRM models 
will be fitted for each key secondary endpoint using a similar model setting as described for the 
analysis of the primary efficacy endpoint.  Fixed sequence procedure will be applied to control 
the overall Type I error rate across all hypotheses in the primary and key secondary endpoints 
at the 0.05 level. 
 
Analysis of Other Secondary Efficacy Endpoints 
Ocular surface disease Assessments 
Change from baseline in Conjunctival fluorescein staining, TFBUT and each individual 
symptom score in the study eye at each analysis visit in Period 1 will be compared between 
treatment groups using MMRM on observed cases. More details on the model specifications will be 
provided in the SAP.

visit in Period 1 will be compared between treatment groups using a Chi-squared test or 
Fisher’s Exact test wherever appropriate for the FAS population. 
Artificial tears use during Period 1will be summarised by treatment group as a continuous 
variable as well as by percentage of patients who use artificial tears at each analysis visit.. 
CSF, corneal and conjunctival fluorescein staining, TFBUT, symptom scores [3-symptom 
average and individual symptom score], and slit lamp examination and their change from 
baseline at each visit will be summarized descriptively by treatment group. 
Quality of Life Assessments 
Mean scores of quality of life (Glaucoma Quality of Life-15), and their change from baseline 
(Period 1 and Periods 1 & 2) and change from Week 12 (Period 2) will be summarized by 
study period,  analysis visit and by treatment group (Period 1), for the FAS population (Period 
1), for the Open-Label Population (Period 2, Periods 1 & 2 combined). 
Subjects Global Rating of Treatment 
Subjects global rating of treatment at Week 12/early termination will be summarized by 
treatment groups for the FAS population. Also, it will be summarized at Month 15/early 
termination for the Open-Label Population.

IOP Assessments 
Changes in peak, trough, and mean diurnal IOPs at each analysis will be summarized on the 
study eye by treatment group.  
Peak, trough, and mean diurnal IOP responses in the study eye (IOP 20%, 25%, 30% responses, 
and IOP < 18 mmHg response) at each analysis visit will be summarized by treatment group.  
For patients participating in the safety follow-up, change from baseline and change from Week 
12, respectively, in mean morning (9:00 am ± 1 hour) IOP will be summarized for the Open-
Label population and for CFS subgroups at Month 6, Month 9 and Month 15/early termination.  
Analysis of Safety and Tolerability Endpoints 
Safety and tolerability endpoints will be summarized for the following three time periods:  
 Period 1 (Day 1 to Week 12 Visit): for whole Safety population by treatment group  
 Period 2 (Week 12 Visit to Month 15 Visit/early termination): for all subjects who 
entered into the open-label period (Open-Label Safety population) 
 Entire study period (Day 1 to Month 15/early termination): for all subjects who 
entered into the open-label period (Open-Label Safety population). 
Adverse Events 
An adverse event is treatment-emergent (TEAE) if it occurs or worsens after the first dose of 
study treatment. A suspected adverse reaction (SAR) is any adverse event for which there is a 
reasonable possibility that the study drug or study procedure caused the adverse event. 
Adverse events will be coded using the MedDRA dictionary. Frequencies and percentages will 
be given as follows:  1) Overall summary; 2) by system organ class and preferred term, 3) by 
system organ class, preferred term and maximal severity, 4) by system organ class, preferred 
term and relationship to study medication and study procedure, respectively, and 5) by system 
organ class, preferred term, maximal severity, and relationship to study medication  and study 
procedure, respectively.  
Separate analyses will be performed for AEs, SARs, SAEs, serious SARs, and for ocular and 
non-ocular events. Ocular events will be summarized for the study eye and the fellow eye 
separately. 
Other Safety Assessments 
Other safety assessment parameters (e.g. slit lamp examination, dilated fundoscopy, BCDVA, 
and visual field) will be summarized by analysis visit. They will be summarized for the study 
eye and the fellow eye separately. Pregnancy test results will be provided in a listing. 
Interim Analysis 
There is no planned interim analysis for this study.

INTRODUCTION 
Glaucoma and IOP 
Glaucoma is a chronic degenerative optic neuropathy that can be distinguished from most other 
forms of acquired optic neuropathy by the characteristic appearance of the optic nerve. Glaucoma 
is the second leading cause of blindness in Europe (EGS, 2017 (1)). In most Western countries, 
glaucoma diagnosis is often made late (Martus, 2005 (2)); approximately half of patients with 
manifest glaucoma are undiagnosed (Tielsch, 1991; Mitchell, 1996; Quigley, 2003 (3-5)). 
In glaucoma, the neuroretinal rim of the optic nerve becomes progressively thinner, thereby 
enlarging the optic-nerve cup. Glaucoma encompasses a group of diseases and is classified by the 
appearance of the iridocorneal angle (anterior-segment variations) that can elevate intraocular 
pressure (Kwon, 2009 (6)). There are open-angle, closed-angle, and developmental categories 
which are further divided into primary and secondary types. Primary open-angle glaucoma 
(POAG) is the most common type in western countries. POAG is a chronic optic neuropathy which 
occurs with an open angle in the absence of any explanatory causes. While there is no standard 
definition, current criteria require the presence of visual field and optic disc damage. OAG can 
occur at any level of intraocular pressure (IOP); with or without elevated IOP; the latter is 
sometimes called normal-tension glaucoma (Leske, 2007; Kwon, 2009 (6, 7)). However elevated 
IOP is the main risk factor for OAG development and reduction of IOP has been demonstrated to 
protect against further damage to the optic nerve, even in patients with normal tension glaucoma. 
Other risk factors of POAG than older age are black race, elevated IOP, family history of POAG, 
myopia or vascular factors (Kwon, 2009 (6)). 
Up to 10% of people over 40 years of age have IOPs above 21 mmHg (normal range 10 to 21 
mmHg); those who have such high pressures but no optic-nerve damage are considered to have 
ocular hypertension. In medical practice, patients who have ocular hypertension should be 
periodically examined (optic nerve, visual fields) to determine whether there is evidence of a 
progressive damage which would indicate the need to start with treatment. However, a high IOP 
without optic-nerve damage, in some cases (e.g. additional risk factors for glaucoma) may be 
treated. 
Glaucoma and ocular surface disease 
Glaucoma and ocular surface disease (OSD) signs and symptoms commonly occur together, and 
this overlap suggests an association between the two diseases. It is estimated that 50% to 60% of 
glaucoma patients have symptoms of OSD, eg. keratitis, conjunctivitis and lid disease (Leung, 
2008; Fechtner, 2010 (8, 9)). Abnormal tear film break-up time (TFBUT) with elevated Ocular 
Surface Disease Index (OSDI) and lissamine green scores were frequent in glaucoma patients 
when compared with controls (Saade, 2015 (10)). OSD has been found to be aggravated by the use 
of preserved topical intraocular pressure (IOP) lowering drugs (Pisella et al, 2002; Baudouin, 2010 
(11, 12)), and to play an important role in patient satisfaction and compliance (Lemij, 2015 (13)). 
In addition, Batra and collaborators recently demonstrated that OSD management resulted in 

DE-130A (latanoprost 50 microg/ml eye drops emulsion, SD) Amendment1 Version 5.0 26 February 2021

improved IOP control, suggesting that improving the ocular surface condition may help in the 
control of IOP (Batra, 2014 (14)). 
Management of Glaucoma  
The current therapeutic approach in open angle glaucoma is lowering IOP by pharmacological 
means, surgery, micro-invasive surgery, or with laser therapy to preserve visual function (Conlon 
et al, 2016; The glaucoma laser trial (GLT), 1995 (15, 16)). It is generally accepted that 
pharmacological treatments should be the first step, and the initial target IOP for each patient 
should be chosen individually according to the current amount of optic damage and the pressure 
at which the damage occurred, and that  the target IOP will be further adjusted according to the 
disease progression in subsequent examinations of visual field. Although different clinical aspects 
will guide the choice of the target initial pressure, it is common to pursue a decrease in the IOP 
between 20% and 40% depending on the degree of associated damage. Once the patient has 
achieved a “safe” IOP at which the disease does not progress, additional lowering of the IOP would 
provide marginal benefit entailing a higher risk of adverse reactions. 
The common goal among the various therapies is to lower the IOP to prevent loss of visual fields 
from excessive pressure on the optic nerve. The IOP level remains the only major glaucoma risk 
factor known to be modifiable. For that reason, there has been long-standing interest in the 
potential of IOP-lowering treatment to decrease OAG risk. Several clinical trials have 
demonstrated the effectiveness of lowering IOP to reduce visual field loss, at the various stages of 
the disease whether of the ‘high pressure’ or ‘’normal pressure’ variety as well as reducing the 
conversion of OHT to POAG (EGS, 2017b (17)). 
Several major classes of therapeutic agents are used in the treatment of glaucoma (EGS, 2017b 
(17)). IOP-L drugs may act in four ways: increasing outflow through the trabecular meshwork; 
increasing uveoscleral outflow; decreasing episcleral venous pressure; and decreasing aqueous 
humor production. Until today, the mechanism of action of IOP-L drugs consists of either 
decreasing aqueous fluid production in the ciliary epithelium, improving aqueous outflow via the 
trabecular meshwork (responsible for 80% of normal outflow) or increasing the uveoscleral route 
(20%), or a combination of both (Parikh, 2008 (18)). Recently, a new therapeutic class, the rho 
kinase and norepinephrine transporter inhibitor (netarsudil), has been developed. It increases the 
outflow from the trabecular meshwork, and may also lower episcleral venous pressure (Lin, 2018 
(19)). In 2018, netarsudil ophthalmic solution was approved by the FDA (Choy, 2018 (20)). 
There are thus five classes of topical antiglaucoma drugs administered as first therapy:  
 Prostaglandin analogues (including prostamins) that increase uveoscleral outflow 
 Beta-receptors agonists (non-selective beta-blockers or selective beta-1-blockers) that 
decrease aqueous production 
 Carbonic anhydrase inhibitors (topical or systemic) that decrease aqueous production 
 Alpha-2 selective adrenergic agonists that decrease aqueous production, and are 
associated with an increase in uveoscleral outflow for brimonidine

26 
 
 Rho kinase and norepinephrine transporter inhibitors which exhibit additive  effects with 
latanoprost. 
Prostaglandin treatment has been shown to provide patients with the highest reduction of IOP 
followed by non-selective b-blockers, alpha-adrenergic agonists, selective b-blockers and at last 
topical carbonic anhydrase inhibitors (van der Valk, 2005 (22)). A recent study showed longer 
visual field preservation in patients with POAG treated with latanoprost compared to those treated 
with placebo (Garway-Health, 2015(21)). Medical treatment is initiated with a topical ophthalmic 
drug (eye drops) and if necessary, a second topical drug is added (EGS, 2017b (17)).

Background on DE-130A 
Santen is currently developing the product DE-130A (formerly NOVA21027 of Novagali Pharma 
today part of SANTEN) which is a preservative-free, sterile ophthalmic emulsion containing 
latanoprost 50 microg/ml intended for topical use for the treatment of elevated intraocular pressure 
in patients with open angle glaucoma and/or ocular hypertension. It is a new formulation of the 
reference IOP lowering medication, Xalatan® (latanoprost 50 microg/ml eye drops solution – 
Pfizer), which was registered in Europe first in December 1996. These two medicinal products 
mainly differ by their pharmaceutical form, Xalatan® being a BAK-preserved eye drops solution 
in a 2.5 ml dropper container while DE-130A is an unpreserved emulsion in a single-dose container. 
4.1.1. 
Background information on the product 
Latanoprost (INN) is a well-known substance, a prostaglandin-analogue isopropyl ester prodrug 
which per se is inactive, but after hydrolysis to the acid of latanoprost becomes biologically active. 
This prostanoid selective prostaglandin F (FP) receptor agonist is believed to reduce the intraocular 
pressure (IOP) by increasing the outflow of aqueous humor. Studies in animals and man suggest 
that the main mechanism of action is increased uveoscleral outflow.  
The cationic emulsions in general (Lallemand, 2012; Daull, 2014; Amrane, 2014; Robert, 2016; 
Leonardi, 2016; Baudouin, 2017 (23-28)), and of latanoprost in particular (Liang, 2009; Daull, 
2012; Daull, 2014; Daull, 2017 (24, 29-31)) were demonstrated to be safe and well tolerated by 
the ocular surface in animal models and patients. 
4.1.2. 
Non-clinical development 
Regarding the active pharmaceutical ingredient (API) used in DE-130A, the ocular as well as 
systemic toxicity of latanoprost has been investigated in several animal species. In animal studies, 
latanoprost has not been found to have sensitising properties.  
In chronic ocular toxicity studies, increased palpebral fissure has been reported at latanoprost 6 
µg/eye/day, this reversible effect has not been seen in humans. Latanoprost was found negative in 
reverse mutation tests in bacteria, gene mutation in mouse lymphoma and mouse micronucleus 
test. Chromosome aberrations were observed in vitro with human lymphocytes, and this indicates 

DE-130A (latanoprost 50 microg/ml eye drops emulsion, SD) Amendment1 Version 5.0 26 February 2021

27 
 
that it is a class effect. Latanoprost has not been found to have any effect on male or female fertility 
in animal studies. No teratogenic potential has been detected with latanoprost. 
Regarding the vehicle used for the drug product DE-130A, latanoprost is formulated in a cationic 
emulsion based on the Novasorb® technology (Lallemand, 2012 (23)).  
The cationic emulsion vehicles possess protective properties for tear film stabilization via its 
interactions with the tear film lipid layer (TFLL) (meibum films) of the tear (Georgiev, 2016; 
Georgiev, 2017 (32, 33)), and help in the prevention of tear film break-up via the interaction of 
cetalkonium chloride (CKC) with the polar lipids of the TFLL (Cwiklik, 2017 (34)). In addition to 
these mechanical actions, the cationic emulsion also harbour intrinsic anti-inflammatory properties 
(Daull, 2016a ; Daull, 2016b (35, 36)) that help in the management of ocular surface inflammation, 
often present on the ocular surface of glaucoma patients, and wound healing properties (Liang, 
2009 (29)). Indeed, latanoprost formulated in cationic emulsion is safe (Daull, 2012 (30)) and 
appears a promising formulation for the management of ocular hypertension and ocular surface 
dryness and subclinical inflammation (Daull, 2017 (31)). 
Furthermore, when compared to either saline or anionic emulsions, submicron cationic emulsions 
have been shown to optimize ophthalmic topical drug delivery after instillation of one single drop 
(Tamilvanan, 2004; Calvo, 1996; Sahin, 2008; Tunc, 2006 (37-40)). 
The non-clinical data generated by Santen during DE-130A development (pharmacodynamics, 
pharmacokinetic and local tolerance) are detailed in the Investigator’s brochure.  DE-130A and 
Xalatan® share a similar pharmacodynamic profile (Study PCS09B001 – non-GLP). Both 
products have efficiently reduced high IOP in monkey glaucomatous eyes.  
The pharmacokinetic and toxicokinetic profiles of DE-130A (local biodistribution and systemic 
exposition) were characterized and compared to the one obtained with Xalatan®. DE-130A has a 
PK profile slightly inferior at short time points when compared to Xalatan®, as reflected by its 
lower exposition (AUC). However, the concentrations observed at 4h and 6h were similar for both 
formulations, suggesting that over a 24h period following a single instillation, DE-130A and 
Xalatan® have the same PK profile from the time point 4h until 24h. Thus, except for some short 
time points DE-130A and Xalatan® are comparable. DE-130A has a slower absorption rate, which 
is compensated by a longer exposition of the emulsion onto the eye surface. The latter being 
responsible for DE-130A concentrations observed at time points 4h and after. 
The local tolerance of DE-130A was assessed on ocular surface and in the nasal mucosa, and 
compared to that of Xalatan® in rabbits (Study To458 – GLP). DE-130A was well tolerated in the 
eye and did not induce any significant changes in the nasal mucosa. The UV-LLNA study (41506 
TSS – GLP) demonstrated that cationic emulsion vehicle containing 0.005% CKC did not show 
any phototoxic or photosensitizing (photoallergic) potential. 
Taking into account the legal basis of the DE-130A dossier, Article 10(3) of Directive 
2001/83/EC, Santen is not anticipating performing any additional non-clinical studies.

4.1.3. 
Clinical development 
Patients with mean baseline IOP of 24-25 mmHg who were treated for 6 months with latanoprost 
one drop once daily demonstrated 6-8 mmHg reductions in intraocular pressure (Patel,1996; 
Baudouin, 2006 (41, 42)). Long-term trials (up to 5 years) have shown that latanoprost 
monotherapy provides clinically significant and sustained IOP reduction (Alm, 2004 (43)).This 
drug is probably one of the most potent IOP-lowering medications currently available and has 
become one of the most useful antiglaucoma agents.  
The cationic emulsion of latanoprost 50 microg/ml eye drops emulsion, SD (DE-130A) has been 
evaluated in two phase II clinical trials conducted by Santen.  
DE-130A was compared to Travatan Z® in subjects with glaucoma or OHT and OSD over a 3-
month treatment period, in the USA (NVG10E118). The 95% confidence interval of the difference 
between treatment groups suggests at least the non-inferiority of DE-130A versus Travatan Z® in 
lowering IOP in patients suffering from OAG or OHT. The analysis of signs and symptoms of 
OSD in these subjects also suffering from OSD showed a statistically significant treatment group 
effect for corneal fluorescein staining (CFS) in favor of DE-130A associated with greater decrease 
in artificial tears usage in the DE-130A group compared with the Travatan Z® group. The safety 
analysis demonstrated the good safety profile of DE-130A, comparable to that of Travatan Z®. 
No safety concerns were raised as a result of this study. 
The second study (NVG09E115) assessed the efficacy and safety of a 3-month DE-130A treatment 
period after a switch from Xalatan®, in IOP-controlled patients with OAG or OHT (IOP 
≤22mmHg) (BAK-preserved latanoprost treatment either in monotherapy or in non-fixed 
combination with BAK-free anti-hypertensive treatment(s) for at least one month) and OSD, in 
France. The mean IOP improvement after the switch to DE-130A , with a mean change from 
baseline of-0.6mmHg at D28  and  -0.8mmHg at D84 (Study NVG09E115 – CSR). An 
improvement in the preexisting mild to moderate signs and symptoms of OSD was observed with 
during the study. DE-130A was very well tolerated and local tolerance after instillation improved, 
in particular for Burning/Stinging which was the most impairing symptom after instillation of 
Xalatan®. 
DE-130A effectively and safely lowered IOP and significantly reduced the signs and symptoms of 
these patients with OSD, demonstrating the benefits of the cationic emulsion on the mechanisms 
underlying OSD beyond it being preservative-free. These benefits may represent an important 
improvement in overall quality of life and convenience for OHT or glaucoma patients with OSD. 
 
4.2. 
Rationale for the Proposed Study 
The current pharmacological therapeutic approach in open angle glaucoma or ocular hypertension 
is lowering IOP. Otherwise, ocular surface disease (OSD) signs and symptoms are commonly 
associated with glaucoma, as 50% to 60% of glaucoma patients present with symptoms of OSD. 
A therapy which results in both lowering IOP and improving OSD signs and symptoms may thus 
positively impact patients’ quality of life and compliance with treatment.

At this stage of the development of DE-130A, a comparison to the reference IOP lowering agent 
(latanoprost) in a different formulation needs to be conducted. In line with the overall development 
program and with the “Guideline on the choice of the non-inferiority margin” (Doc. Ref. 
EMEA/CPMP/EWP/2158/99), the non-inferiority study design seems appropriate to compare DE-
130A with a different latanoprost eye drop solution. Latanoprost is available as Xalatan® in 
multidose containers or as Monoprost® in single dose containers (packaging similar to DE-130A). 
Monoprost® has only showed a non-inferiority to Xalatan®, and as mentioned in the CHMP 
advise (EMA/CHMP/SAWP/797001/2017), the comparison to preservative-free Monoprost® in 
single dose containers would have led to a questionable double bridging exercise from a scientific 
perspective; even though the comparison between DE-130A and Xalatan® prevents a double-
masked study. In fact, a double-masked study comparing DE-130A with Xalatan® would have 
required a double instillation of the active product and the placebo of the other study treatment 
(which may have led to bias by modifying the contact time of the study treatment). The 
formulations of DE-130A (preservative-free ophthalmic oily emulsion of latanoprost) and of 
Xalatan® (BAK-preserved eye drops solution) are most likely to exibit significantly different 
physicochemical properties, such as viscosity or surface-tension. Furthermore the high viscosity 
of DE-130A may impact the contact time of the active compound with the ocular surface. 
In the proposed non-inferiority study, to approximate the peak and trough times, the IOP will be 
measured at 9:00 (±1 hour) am and 4:00 (±1 hour) pm, and will be used to assess the primary 
efficacy endpoint and secondary endpoints during a 3-month period with randomised investigator-
masked medication. The chosen non-inferiority margin of 1.5 mmHg is well below (Musch, 2006 
(44)) the effect of the active control (−8.6±2.6 mmHg, Rouland, 2013 (45)). In addition to the 
comparison of peak, trough, and mean diurnal IOP, the rates of different responders (defined by a 
reduction in mean IOP of ≥ 20%, ≥ 25%, and ≥ 30%, and a mean IOP < 18mm Hg) will be 
compared between treatment groups.  
Regarding the OSD, the potential positive impact of the cationic formulation of DE-130A on OSD 
signs (using TFBUT, slit lamp examination, corneal, and conjunctival fluorescein staining with 
modified Oxford scale) and symptoms (using 3-symptom assessment) will be compared with the 
effect on OSD of the BAK-preserved Xalatan®. Furthermore the quality of life impact will also 
be compared between treatment groups. 
In this context, to ascertain the efficacy and safety according to patients severity, the randomisation 
will be stratified in order to prevent to high heterogeneity between treatment groups, with two 
OSD classes (baseline CFS≤1 and ≥2, modified Oxford scale).  
Regarding the trial duration, the previous trials with DE-130A had a duration of 3 months, in 
particular DE-130A ophthalmic emulsion has demonstrated its efficacy in controlling IOP over a 
3-month treatment period after a switch from Xalatan®. Three-month treatment duration is thus 
consistent to assess the IOP reducing effect. However in order to provide long-term additional data 
on the safety and tolerability of DE-130A, a 12-month follow-up with open-label DE-130A is to 
be offered to 130 patients (whatever their randomised treatment is) who complete their Week 12 

DE-130A (latanoprost 50 microg/ml eye drops emulsion, SD) Amendment1 Version 5.0 26 February 2021

Visit and agree to participate in the open-label period of the study. During this safety follow-up, 
only the peak IOP will be measured in order to minimize patients’ burden. 
In order to compare patients with the most homogenous IOP baseline, the study treatment period 
will be preceded by a wash-out period of previous glaucoma medications. Regarding OSD, the use 
of artificial tears (AT) will be protocolized (i.e. ATs with main impact on OSD will be excluded 
and the use of authorized AT will be in agreement with the SmPCs) to allow a comparison between 
treatment groups. 
As a result, the planned multinational, multicenter, investigator-masked, randomised, active-
controlled phase III clinical trial (0130A01SA) aims to demonstrate the non-inferiority of DE-
130A ophthalmic emulsion (cationic emulsion of latanoprost 50 microg/ml eye drops) compared 
to BAK-preserved latanoprost 50 microg/ml eye drops ophthalmic solution (Xalatan®) instilled 
once daily to patients suffering from OAG or OHT. Secondary objectives will include the 
comparison of the efficacy between treatment groups regarding IOP and OSD, and their 
safety/tolerability over the 3-month treatment period. In a subgroup of patients eligible for 12-
month follow-up with open-label DE-130A administration, the same objectives will be assessed 
over a 15-month study period. 
4.3. 
Benefit Risk Assessment  
The patients participating in the study will benefit either from the reference product (Xalatan®) to 
treat their OAG or OHT, or from DE-130A a novel BAK-free formulation of latanoprost with 
potential impact on OSD frequently observed in patients with OAG, in addition to the expected 
IOP-lowering effect. 
After the 3-month treatment period, a 12-month safety follow-up with open-label DE-130A is to 
be offered to the first 130 patients (whatever their randomised treatment is), who complete their 
Week 12 Visit and agree to participate in the open-label period of the study, in order to provide 
them the opportunity to continue their treatment with open-label DE-130A. The supernumerary 
patients will exit the study at Week 12. 
After the study end, patients will receive the best available treatment in the investigator’s opinion 
for OAG or OHT.  
 
Furthermore, patients will benefit from a close follow-up by the investigators (at Week 4 and Week 
12) which is not the case in the usual clinical setting during the first 3 months of a new treatment 
regime, and those patients entering the 12-month study extension will benefit from biannual visits. 
The risks related to the participation in the study are the adverse events listed in the investigator’s 
brochure, the potential risk of allergy to fluorescein, and anaesthetic eye drops or artificial tears.  
In light of the points listed above the benefit risk profile is considered to be favourable.

INVESTIGATIONAL PLAN 
6.1. 
Overall Study Design 
The proposed 3-month phase III study is a prospective, interventional, multinational, multicentre 
investigator-masked, randomised, active-controlled trial to demonstrate the non-inferior IOP 
reducing effect of DE-130A (latanoprost 50 microg/ml preservative-free eye drops emulsion) 
compared to Xalatan® (latanoprost 50 microg/ml BAK-preserved eye drops emulsion) over a 12 
weeks treatment period (Period 1) in patients with OAG or OHT. In addition, after Week 12, a 12-
month follow-up with open-label DE-130A in a subgroup of patients (n=130) will estimate the 
long-term safety and tolerance and explore the long-term efficacy of DE-130A (Period 2). This 
Period 2 will be open in some countries only. 
After a wash-out phase (5 days to 6 weeks) depending on previous IOP lowering medications 
patients will enter: 
• 
A investigator-masked randomised 12-week treatment period (Period 1, DE-130A and 
Xalatan® groups randomised in 1:1 ratio),  
• 
Followed by a 12-month open-label follow-up treatment period (Period 2, open-label DE-
130A once daily) only for the first 130 patients who complete the Week 12 visit and agree 
to participate in the open-label period of the study  
The study duration (including the wash-out period) will be up to 17 months, and patients will 
attend up to 6 scheduled visits after Screening visit (Table 3). 
In order to assess the primary endpoint, patients will be randomly (1:1) allocated to either DE-
130A or Xalatan® once daily in the evening for Period 1 (Figure 1). Furthermore, in order to 
minimize the effect of baseline ocular surface disease severity, the randomisation will be stratified 
by baseline CFS scores (CFS ≤ 1 vs. CFS ≥ 2, modified Oxford scale).

Notes:  
* Start of the open-label DE-130A 12-month safety follow-up for the first 130 patients who complete their Week 12 visit and 
agree to participate in the open-label period of the study. 
** End of study for patients who do not participate in the open-label period of the study. 
*** Brinzolamide will be stopped 5 days before randomisation (6 to 7 days if over the weekend). At Day 1, if IOP is <22 mmHg, 
the wash-out period can be extended and the IOP should be re-assessed two to three days after the first measurement. If the IOP 
is still < 22 mmHg at the second measurement, a third assessment should be performed two to three days after the second 
measurement. If the IOP is still < 22 mmHg at the third  measurement, the patient cannot be randomized in the study. 
 
Study visit schedule and assessments are summarized in Table 3. 
 Wash-out Phase  
After the signing of the informed consent and upon completion of the Screening Visit, all eligible 
study participants will undergo a wash-out phase. 
Prior therapies for OAG or IOP must be discontinued during a wash-out phase of at least 5 days 
and up to 6 weeks (according to the IOP lowering medications currently used at the Screening 
Visit). Washout periods should be as follows: 
• 
Prostaglandin analogs  = 4 weeks 
• 
Topical beta blockers ≥ 3 weeks and ≤ 4 weeks 
• 
Topical carbonic anhydrase inhibitors  ≥ 5 days and ≤ 4 weeks 
• 
All other IOP lowering medication ≥ 2 weeks and ≤ 4 weeks 
During this wash-out period, topical IOP-lowering medication will be replaced by brinzolamide* 
(Azopt®) one drop twice daily. Then brinzolamide will be stopped 5 days (6 to 7 days if over the 
weekend) before randomisation.

*Patients already receiving brinzolamide prior to the Screening Visit will have to stop their 
treatment for a 5-day washout phase before randomisation (without needing to receive again the 
brinzolamide provided by the Sponsor). 
Five days before the Baseline Visit, brinzolamide will end (5-day period without IOP lowering 
medication) as the purpose of the wash-out phase is to select patients for study inclusion with a 
post-washout peak IOP ≥ 22 mmHg and ≤ 32 mmHg (defined as the Baseline Visit [Day 1] mean 
IOP at 9:00 am [±1 hour], see Appendix A-IV) in at least one eye. At baseline, if IOP is <22 
mmHg, the wash-out period can be extended and the IOP should be re-assessed two to three days 
after the first measurement. If the IOP is still < 22 mmHg at the second measurement, a third 
assessment should be performed two to three days after the second measurement. If the IOP is still 
< 22 mmHg at the third  measurement, the patient cannot be randomized in the study.  
Brinzolamide will be provided by the Sponsor. During the wash-out phase protocol-authorised 
artificial tears (AT, see Section 8.2) are allowed but within the SmPC recommendations. 
After the 5 days (6 to 7 days if over the weekend) without any IOP-lowering medication at the end 
of the wash-out phase, patients will undergo the Baseline Visit (Day 1). Patients who meet the 
inclusion criteria for IOP ≥ 22 mmHg and ≤ 32 mmHg [defined by a mean IOP at 9:00 am (±1 
hour)] in at least one eye will be randomised in 1:1 ratio to either DE-130A or Xalatan® (one drop 
once daily in the evening) for Period 1 of the study. Patients not fulfilling the inclusion criteria 
following the wash-out phase will be withdrawn from the study without having received the study 
medication, and they will start the best treatment for their condition according to their 
ophthalmologist’s opinion.  
Eligible patients will thus enter the Study Treatment Periods. 
 Study Treatment Period 1  
During Baseline Visit (Day 1), patients will be instructed to instil one drop of the investigator-
masked study treatment once daily in the affected eye(s) (unilateral or bilateral OAG/OHT), and 
they will be scheduled for 2 additional study visits [Week 4 (± 3 days), Week 12 (± 3 days)] to 
assess the peak and trough IOPs [at 9:00 am (±1 hour) and 4:00 pm (±1 hour), respectively].  
The following other assessments will be performed prior to the morning (9:00 am ±1 hour) IOP 
measurement: 
• 
Evaluation of OSD signs [corneal and conjunctival fluorescein staining (scored with 
modified Oxford Scale), tear film break-up time (TFBUT)], 
• 
Completion of quality of life questionnaires (Glaucoma Quality of Life-15),  
• 
Evaluation of ocular tolerance [including slit lamp biomicroscopy and best corrected visual 
acuity (BCVA)] and systemic safety (medical/medication update). 
• 
Assessement of the Subject Global Rating of Treatment, at Week 12 visit. 
At Week 12, after the trough IOP (4:00 pm), a dilated fundoscopy will be carried out. 
At Week 12 and early termination visit, a urine pregnancy test will be performed on all females of 
childbearing potential.

Confidential 
37 
 
At Week 12, the 130 first patients who complete Period 1 and agree to the open-label follow-up 
will enter Study Treatment Period 2, while the supernumerary patients will exit the study.   
 
 
 Study Treatment Period 2  
At Week 12 visit, the eligible patients for Period 2 will start the 12-month open-label treatment 
Period 2 study: 
During Period 2, 3 additional study visits [Month 6 (±7days), Month 9 (± 7 days), and Month 15 
(± 7 days)] will be scheduled to assess the safety and tolerability of DE-130A. The morning IOP 
[at 9:00 am (±1 hour)] will be measured. 
The following other assessments will be performed prior to the IOP measurement: 
• 
Evaluation of OSD signs [corneal and conjunctival fluorescein staining (scored with 
modified Oxford Scale), tear film break-up time (TFBUT)], 
• 
Completion of  quality of life questionnaires (Glaucoma Quality of Life-15),  
• 
Evaluation of ocular tolerance [including slit lamp biomicroscopy and best corrected visual 
acuity (BCVA)] and systemic safety (medical/medication update). 
• 
Assessement of the Subject Global Rating of Treatment, only at Month 15 visit. 
At Month 15 Or early termination visit, women of childbearing potential will performed a urine 
pregnancy test. 
At Month 15 visit, after the morning IOP, a dilated fundoscopy will be carried out.  
In addition to the study medication, during the whole study, patients will also be allowed to use, if 
needed, unpreserved artificial tears to improve their dry eye symptoms. Patients must be instructed 
not to use artificial tears within 30 minutes before or after use of the study medication and within 
two hours before a scheduled study visit. All other concomitant medications will be recorded on 
the electronic case report form (eCRF). A change in the use of the study treatments or any use of 
topical eye drops other than the study medication, or topical medications allowed during the study 
will be considered a protocol violation. In this clinical trial, the emergence of complications and 
the safety of study treatment will be assessed at each visit up to the exit visit (Month 15 for the 
first 130 patients who completed their Week 12 Visit and willing to participate in the 12-month 
open-label period of the study and Week 12 for the supernumerative patients). 
6.2. 
Number of Subjects 
Approximately 380 patients with Open-Angle Glaucoma (OAG), or ocular hypertension (OHT) 
(190 in DE-130A group and 190 in Xalatan® group) will be randomised in this study to obtain 
173 evaluable patients per treatment group at Week 12 (assuming a dropout rate of 10%).

27. Patient has any condition or situation that, in the Investigator’s opinion, might 
confound the results of the study, may put the patient at significant risk or might 
interfere with the patient’s ability to participate in the study. 
7.4. 
Screen Failure 
Investigators must account for all patients who sign informed consent. If the patient is found to be 
not eligible at screening or baseline visit, the investigator should complete the eCRF for all  
assessments they performed. 
The primary reason for screen failure should be recorded in the eCRF using the following 
categories: 
 
Did not meet inclusion criteria or did meet exclusion criteria. 
 
Adverse events 
Patient numbers assigned to patients who fail screening should not be reused. Re-screening is 
possible.  
 
7.5. 
Subject Withdrawal Criteria 
The primary reason for discontinuation or withdrawal of the patient from the study should be 
recorded in the electronic case report form (eCRF) using the following categories.  
1. Adverse event (AE). The patient has experienced a AE that requires early termination 
because continued participation imposes an unacceptable risk to the patient’s health or 
the patient is unwilling to continue because of a AE. Patients discontinued for drug –
related AE(s) will be followed-up after patient’s discontinuation until the event is 
resolved, stabilized or a final assessment can otherwise be done by the investigator. 
2. Protocol deviation. The discovery after administration of the first dose of study drug 
that the patient failed to meet protocol entry criteria or did not adhere to protocol 
requirements, and continued participation poses an unacceptable risk to the patient’s 
health. 
3. Lost to follow-up. The patient did not return to the clinic and attempts to contact the 
patient were unsuccessful. In case of a patient lost-to-follow-up, the investigator must 
do his/her best to contact the patient initially by phone, then by letter, and finally by 
certified mail. If no response is obtained from the patient, the investigator is 
encouraged to contact one of the patient’s relatives or his/her general physician. 
These attempts must be documented and associated documentation filed in the patient 
medical chart. 
4. Voluntary withdrawal. The patient (or patient’s legally acceptable representative) 
wishes to withdraw from the study. The reason for withdrawal, if provided, should be 
recorded in the eCRF. 

DE-130A (latanoprost 50 microg/ml eye drops emulsion, SD) Amendment1 Version 5.0 26 February 2021 
 
Confidential 
43 
 
Note: All attempts should be made to determine the underlying reason for the 
withdrawal and, where possible, the primary underlying reason should be recorded (i.e., 
withdrawal due to an AE should not be recorded in the “voluntary withdrawal” 
category). 
5. Study termination. The Sponsor, IEC, or regulatory agency terminates the study. 
6. Lack of efficacy. the patient or the physician does not feel that the study medication 
has adequately relieved his/her symptoms. 
7. Pregnancy. The patient is found to be pregnant.  
Note: If the patient is found to be pregnant, the patient must be withdrawn immediately.  
8. Investigator decision due to non-compliance (to IMP, study visits or study related 
procedure). 
9. Other reason, specify. 
Note: All attempts should be made to determine the reason if Other is chosen (e.g. 
moving) and specific primary reason should be recorded in the “specify” field of the 
eCRF. 
 
7.6. 
Procedures for Discontinuation or Withdrawal of a Patient 
The investigator may terminate a patient’s study participation at any time during the study when 
the patient meets the study withdrawal criteria described in Section 7.5. Efforts should be made 
to perform all procedures scheduled for the Week 12/Month 15/Early Termination (ET) visit. 
Discontinued patients will not be replaced. 
 
7.7. 
Completed Enrolment 
The study enrolment will be considered as completed when the desired number of at least 380 
patients is randomised. Patients between the screening visit and the baseline visit at the time the 
desired number of 380 randomised patients is achieved, are eligible for inclusion if they fulfil the 
inclusion/exclusion criteria at the Baseline Visit (Day 1).

TREATMENT OF SUBJECTS 
8.1. 
Description of Study Drug  
8.1.1. 
DE-130A 
DE-130A 50 microg/ml eye drops emulsion, SD is formulated as sterile, preservative free, 
positively charged (cationic) oil-in-water ophthalmic emulsion using well-known excipients. It 
contains 50 micrograms of latanoprost per ml of emulsion. DE-130A is an oil-in-water emulsion, 
in which the oil droplets, containing latanoprost, are dispersed in the aqueous phase (see the 
Investigator’s Brochure). 
DE-130A contains the following excipients:   
- 
Medium Chain Triglycerides (MCT; w/w: 1.0%): the emulsion’s oily agent that 
constitutes the main droplet core component and solubilizes the drug. 
- 
Cetalkonium chloride (CKC; w/w: 0.005%): a cationic (positively charged) surfactant 
that ensures the emulsion stability by providing a positive charge to the oil droplets and 
consequently an electrostatic repulsion between droplets.  
- 
Polysorbate 80 (w/w: 0.050%) is a non-ionic surfactant and it is used to obtain stable 
emulsion.  
- 
Glycerol (w/w: 2.400%) is used to make the emulsion isotonic. Glycerol was selected as 
osmotic agent because it does not destabilize the emulsion. 
- 
Water for injections is added as a solvent  
Batch number and expiration dates of the investigational drug will be provided in the certificate 
of analysis. 
8.1.2. 
Xalatan® 
Xalatan® composition is described in its SmPC. Its active substance is latanoprost (50 
microg/ml) and excipients include sodium chloride, benzalkonium chloride (BAK, 0.02%), 
sodium dihydrogen phosphate monohydrate, anhydrous disodium phosphate, water for 
injections. 
 
8.2. 
Azopt® 
Azopt® will be provided to the patients for the wash out prior to the Day 1 visit.  
Patients already receiving brinzolamide prior to screening visit will have to stop their treatment 
for a 5-day washout before randomisation (6 to 7 days if over the weekend) without any need to 
receive again the brinzolamide provided by the Sponsor. At baseline, if IOP is <22 mmHg, the 
wash-out period can be extended and the IOP should be re-assessed two to three days after the 
first measurement. If the IOP is still < 22 mmHg at the second measurement, a third assessment 

DE-130A (latanoprost 50 microg/ml eye drops emulsion, SD) Amendment1 Version 5.0 26 February 2021 
 
Confidential 
45 
 
should be performed two to three days after the second measurement. If the IOP is still < 22 
mmHg at the third  measurement, the patient cannot be randomized in the study. 
Azopt® composition is described in its SmPC. Its active substance is brinzolamide (10mg/ml). 
 
8.3. 
Concomitant Medications/Therapies 
Concomitant therapies consist of any treatment or medication given concurrently with the study 
medication. The following concomitant medication(s)/treatment(s) are prohibited during study 
participation:  
- 
Use of any preserved artificial tears  
- 
Use of preservative free artificial tears over the SmPC recommended regimen  
- 
Use of Cationorm® 
- 
Use of any topical ocular treatments other than the study medication except 
preservative free artificial tears used according to the SmPC recommended regimen  
(but these artificial tears usage should remain stable during the course of the study).  
- 
Any refractive surgery (LASIK, LASEK, PRK, etc.) during the course of the study. 
The initiation or use during the course of the study of any treatments or procedures described above 
will be considered as a protocol deviation. 
8.4. 
Treatment Compliance 
Patient compliance will be assessed at each visit by pharmacist or person in charge of study 
delivery by questioning the patient and comparison to drug accountablity. All reported incidents 
of the lack of compliance will be recorded on the eCRF with the reasons. If a patient is persistently 
noncompliant with the study medication, the patient should be withdrawn from the study. All 
patients should be reinstructed about the dosing requirement during study visits. The authorized 
study personnel conducting the re-education must document the process in the patient source 
records. 
8.5. 
Randomisation and Masking  
At Baseline visit (Day 1), subjects who are eligible for the study will be randomly assigned (by 
the IWRS) in a 1:1 ratio to receive either DE-130A or Xalatan® for 12 weeks in a investigator-
masked fashion. The randomisation will be stratified according to the CFS score of the study eye 
at Baseline visit (CFS ≤ 1 vs. CFS ≥ 2, modified Oxford scale). A computer algorithm for random 
number generation will be used to generate the treatment assignments.  
Treatment assignments will be masked to Investigators. The investigator should try to avoid 
knowing the masked treatment. However, IN CASE OF EMERGENCY ONLY, (i.e. SERIOUS 
ADVERSE EVENT AND ONLY WHEN THIS INFORMATION INFLUENCES THE 
PATIENT'S MANAGEMENT), the investigator may unmask the patient by using IWRS, in 
order to obtain the study medication information (i.e. DE-130A or Xalatan®) to immediately start

the appropriate treatment [to be recorded in the source data and eCRF (electronic Case Report 
Form)]. A record will be made for the date, time and reason for breaking the code. The investigator 
should inform the Sponsor immediately after unmasking. The details of this unmasking procedure 
will be described in a separate document. Patients unmasked for the management of a SAE will be 
discontinued from the study.  
Treatment masking to the patients would be impossible due to the difference in the appearance of 
the DE-130A and Xalantan eye drops. But the patients shall not be explicitely told about the name 
of the study drug by the drug dispensing staff. Every effort will be made to keep all study team 
members involved in the study masked during the whole Period 1 study period, this shall include 
Santen personnel (except for drug supply personnel), CRO personnel (including CRAs except the 
ones in charge of accountability), and staffs at all clinical centers (except the drug dispensing 
person), etc.

Study Drug Storage 
All clinical trial material must be kept in an appropriate, limited-access, secure location until it is 
used or returned to the sponsor or designee for destruction. All study medication must be stored 
under the conditions specified on the label, and remain in the original container until dispensed. A 
daily temperature log of the drug storage area must be maintained every working day. Any 
temperature excursion of study drug should be notified to the sponsor and the supplies placed in 
quarantine before further instruction is received from the sponsor. The study medication will be 
delivered to the study centres by the clinical supplies distributor.  
The study medication, DE-130A must be stored below 30°C and it must not be frozen. After 
opening of the aluminium pouch, the single dose container should be kept in the original pouch in 
order to avoid evaporation.  The single dose container is to be used immediately after opening and 
the contents of one single dose container is sufficient for both eyes. The remaining content of the 
single dose container sould be discarded immediately after administration.  
The study medication Xalatan® must not be stored above 25°C and after opening of container 
used within four weeks. Keep the container in the outer carton box in order to protect from light. 
  Initially each centre will receive adequate supplies of study medication to cover the study 
treatment period for a pre-defined number of patients. Additional supplies will be dispatched after 
taking into account the recruitment rate of each study centre. The investigator or his/her designee 
will be responsible for correct handling and storage of the study medication during the course of 
the study.

as directed by Santen (or designee). A copy must be maintained at the site for the Investigator’s 
records. The Principal Investigator will keep a current record of the inventory and dispensing of 
all study drugs. This record will be made available to CRO or Santen Monitor (or designee) for 
the purpose of accounting for all clinical supplies. Any discrepancy and/or deficiency must be 
recorded with an explanation. All supplies sent to investigator must be accounted for and in no 
case will study drugs be used in any unauthorized situation.  
It is a responsibility of the Principal Investigator to return any unused supplies to  Santen monitor 
(or designee) at the conclusion of the study.  
Subjects are instructed to return all unused Single Dose containers, pouches and cardboard box 
of DE-130A and all used and unused IMP bottles and cardboard box of Xalatan® at the next 
visit. The used SD containers should be discarded by the subject after daily drop(s) have been 
instilled. Subjects are instructed to return wash-out medication including outer cardboard box 
back to the site at Baseline visit (Day 1). 
Upon completion or earlier termination of the study the investigator will, unless otherwise agreed, 
return to the clinical supplies distributor any surplus quantities, unused single dose containers and 
used and unused bottles, of study medication. The investigator will record each quantity of study 
medication that has been damaged or is missing. 
Drug supplies will be counted and reconciled at the site before being returned to Santen or 
designee or being destroyed by the site after Sponsor written approval.

11. 
ASSESSMENT OF EFFICACY 
11.1. 
Tonometry for measurement of Intraocular Pressure (IOP) (mmHg) 
IOP will be measured using Goldman applanation tonometry (one measurement), after instillation of 
one drop of oxybuprocaine 0.4% and fluorescein 2% solutions (both solutions provided by the 
Sponsor) (Appendix A-IV) . IOP will be assessed after completion of all other slit lamp examinations 
and dry eye assessments to avoid oxybuprocaine interference with the other examinations.  
Morning IOP must be performed at 9:00 am and afternoon IOP at 4:00 pm. all IOP measurements 
must be conducted within +/- 1 hour of the required time points. 
The patient and slit lamp should be adjusted so that the patient’s head is firmly positioned on the 
chin rest and against the forehead rest without leaning forward or straining.  Both eyes will be tested, 
with the right eye preceding the left eye. The same equipment must be used throughout the course of 
the study.  
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. 
 
11.2. 
Corneal and Conjunctival Fluorescein Staining  
Corneal and conjunctival fluorescein staining will be assessed immediately following the TFBUT.  
Reading will be performed between 1 and 4 minutes after fluorescein instillation for the TFBUT, to 
ensure that the dye does not diffuse into stroma blurring the discrete margin of any staining defects. 
The eye will then be examined at the slit lamp (16X magnification) using a yellow barrier filter and 
cobalt blue illumination to enhance visibility of staining.  
Staining using fluorescein (provided by the Sponsor) will be graded using the modified Oxford scale 
(7-point ordinal scale, score 0, 0.5, and 1 to 5 per area [cornea + nasal and temporal conjunctiva]) 
for cornea and conjunctiva separately, see Appendix A-III. On this modified scale, the score 0 
corresponds to no staining dots and the score 0.5 corresponds to one staining dot per area.  
A CFS grade of 0 represents complete corneal clearing. 
A negative change score from baseline (Period 1) and/or from Week 12 (Period 2) will indicate 
improvement. 
11.3. 
Tear Film Break-Up Time 
Tear film break-up time (TFBUT) will be measured by determining the time to tear break-up.   
The tear film break-up time (TFBUT) measurement is performed in conjunction with 
corneal/conjunctival fluorescein staining. 2 μl of non-preserved 2% sodium fluorescein is instilled 
onto the bulbar conjunctiva of each eye without inducing reflex tearing by using a micro-pipette. 

DE-130A (latanoprost 50 microg/ml eye drops emulsion, SD) Amendment1 Version 5.0 26 February 2021 
 
Confidential 
61 
 
To thoroughly mix the fluorescein with the tear film, the patient will be instructed to blink several 
times. In order to achieve maximum fluorescence, the examiner should wait approximately 30 
seconds after instillation before evaluating TFBUT. With the aid of a slit lamp at 10X magnification 
using cobalt blue illumination, the examiner will monitor the integrity of the tear film, noting the 
time it takes to form lacunae (clear spaces in the tear film) from the time that the eye is opened after 
the last blink. The TFBUT will be measured twice during the first minute after the instillation of the 
fluorescein, by using a stop watch. If the 2 readings differ by more than 2 seconds, then a third 
reading will be taken.  
The TFBUT value will be the average of the 2 or 3 measurements.  
A positive change from baseline (Period 1) and/or from Week 12 (Period 2) will indicate 
improvement. 
11.4. 
Slit lamp examination 
External ocular examination and undilated biomicroscopy will be performed using a slit lamp. The 
subject will be seated while being examined; grading of the Meibomian glands, lids, lashes, 
conjunctiva, tear film debris, anterior chamber and lens will be done according the scales in 
AppendixA-II. 
Slit lamp examination will also be used as a safety assessment (see 12.1.2).  
11.5. 
Dilated and undilated fundoscopy 
After the dilatation of the pupil with mydriatic eye drops, the fundus examination will be performed 
to assess the retina, optic nerve head, blood vessels. Cup-to-disc (C/D) ratio will be evaluated to 
assess the progression of glaucoma (Appendix A-VI).  At Baseline, Week 4, Month 6, and Month 9 
the fundoscopy will be done without dilatation. 
11.6. 
Use of Concomitant Artificial Tears 
The use of unpreserved artificial tears will be monitored over the course of the study for each patient. 
Patients will be asked about the average number of times per day artificial tears was used over the 
last week, and number of days they were not used during the week preceding the visits. 
11.7. 
Symptom Assessment 
Symptoms of ocular discomfort (unrelated to instillation of the study medication), including 
burning/stinging/itching, dry eye sensation, and blurred/poor vision will be done according to the 
scales in Appendix A-I.   
 
11.8. 
Subject global rating of treatment 
 
At Week 12 Visit (for subjects not participating in the open-label extension study) or at Month 15 
Visit (for subjects who participate in the open-label extension study), or at early termination visit, a 
staff member will ask the subject the following question during the office visit: “Please select one of 
the following 4 choices to rate your overall assessment of the effect of the glaucoma study medication

Adverse Events (AEs) 
Adverse events, including ocular AEs, ocular complications, and systemic AEs will be recorded in 
the eCRFs. Any clinically significant change in concomitant disease or new concomitant conditions 
that occurred between the Screening Visit and the Baseline Visit will be reported as AEs. 
12.1.4. 
Pregnancy Screen 
Women of childbearing potential cannot be included in the study if they are not using a medically 
acceptable, highly effective method of birth control (such as hormonal implants, injectable or oral 
contraceptives, intrauterine devices, sexual abstinence or vasectomized partner) from the Screening 
Visit throughout the conduct of the study treatment periods and up to 2 weeks after the study end. 
Sexual abstinence is defined as refraining from heterosexual intercourse during the entire study 
period and should be in line with the preferred and usual lifestyle of the subject. Post-menopausal 
women (two years without menstruation) do not need to use any method of birth control. For women 
of childbearing potential only, urine hCG pregnancy tests provided by the sponsor will be performed 
during the course of the study, and they will receive continued guidance with respect to the avoidance 
of pregnancy, as part of the Schedule of Study Procedures

Adverse Events and Other Safety Information 
12.2.1. 
Definitions 
12.2.1.1. Adverse Event (AE) 
An adverse event is any untoward medical occurrence in a clinical investigation subject administered 
a study drug. An AE does not necessarily have a causal relationship with the study drug.  For this 
study, the study drugs are DE-130A (latanoprost 50 microg/ml eye drops emulsion) and Xalatan® 
(latanoprost 50 microg/ml eye dropssolution). An AE can be any unfavourable unintended sign 
(including for example an abnormal laboratory finding), symptom, or disease temporally associated 
with the use of study drug which does not necessarily have to have a causal relationship with the 
study treatment.  
In general, changes in clinical safety variables will be recorded as AEs if clinically significant 
changes as judged by the investigator occur during the study. These may include, but are not limited 

DE-130A (latanoprost 50 microg/ml eye drops emulsion, SD) Amendment1 Version 5.0 26 February 2021 
 
Confidential 
65 
 
to, cases where a patient spontaneously reports a new symptom or when a change from baseline of 
clinical importance as judged by the investigator occurs. A clinically significant worsening in 
severity, intensity, or frequency of a pre-existing condition may indicate an AE.  
Worsening of findings e.g. in biomicroscopy from no findings to finding graded as moderate/severe, 
or change in grading from mild to severe, may be an indication of an AE. By investigator’s judgment, 
also milder changes can be recorded as AEs. 
An elective surgical procedure scheduled or planned prior to study entry 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 lack of efficacy of the study treatment for the condition being investigated is not considered an 
AE unless a clinically significant change in the patient’s condition is assessed by the investigator. 
Patients’ answers given to study questionnaires (or changes in these) are not reviewed as a basis for 
occurrence of AEs. However, the investigators will collect information on AEs at each subject 
contact by asking an open question on the subject’s general health. 
12.2.1.2. Serious Adverse Event (SAE) 
A serious AE may occur during any study phase (ie, screening, baseline, treatment, washout, or 
follow-up) at any dose of the study drug, comparator or artificial tears.  Serious AEs are abbreviated 
as ‘SAEs’ in the protocol. SAE must  fulfil one or more of the following criteria: 
 Results in death 
 It is immediately life-threatening* 
 It requires in-patient hospitalization or prolongation of existing hospitalization 
 It results in persistent or significant disability or incapacity 
 Results in a congenital abnormality or birth defect 
 It is an important medical event that may jeopardize the patient or may require medical 
intervention to prevent one of the outcomes listed above (including sight-threatening** 
events and cancer or neoplasm of any type). 
*Herein ‘Life-threatening’ refers to an event in which the patient was at immediate risk of death at the time of event; it 
does not refer to an event which hypothetically might have caused death.  
**Similarly ‘Sight-threatening’ refers to an event in which the patient was at immediate risk of losing sight; it does not 
refer to an event which hypothetically might have caused losing of sight. 
Serious ocular adverse events include, but are not limited to the following adverse events which are 
considered to be sight-threatening and are to be reported as SAEs (medically important criteria): 
- 
Adverse Events that caused a decrease in visual acuity of >6 lines (compared with the last 
assessment of visual acuity at the last visit) 
- 
Adverse Events that caused a decrease in visual acuity to the level of Light Perception or 
worse 
- 
Adverse Events that required surgical intervention or laser to prevent permanent loss of sight 
- 
Adverse Events associated with severe intraocular inflammation (i.e., 3+ anterior chamber 
cell/flare or 3+ vitritis)

- 
Corneal perforation 
- 
Adverse Events that, in the opinion of the investigator,  may require medical intervention to 
prevent permanent loss of sight 
12.2.1.3. Case of Special Interest (CSI) 
The following cases are considered to be of special interest by the Sponsor: 
- 
Non-serious AEs requiring (24 h) reporting to the sponsor: 
 Corneal ulceration 
 Decrease in visual acuity of 3-6 lines (compared with the last assessment of visual 
acuity at the last visit) 
- 
Overdose of study drug 
 Administration of a quantity of a medicinal product exceeding the dose defined in the 
study protocol. 
- 
Misuse of study drug 
 Situations where the medicinal product is intentionally and inappropriately used not 
in accordance with the study protocol. 
- 
Medication error 
 Any unintentional error in the prescribing, dispensing, or administration of a 
medicinal product while in the control of the healthcare professional or patient. 
- 
Abuse of study drug 
 Persistent or sporadic, intentional excessive use of medicinal product which is 
accompanied by harmful physical or psychological effects. 
12.2.1.4. Pregnancy Reports 
It is required that women of childbearing potential are using a medically acceptable, highly effective 
method of birth control during the study and up to 2 weeks after the study end. Any pregnancy 
occurring during the study or within 14 days of completing the study should be reported to Santen 
EMEA Safety Vigilance (SV) and the subject will be removed from the study. 
Pregnancies in partners of study subjects with paternal drug exposure must also be reported to Santen 
EMEA SV. 
12.2.2. 
Assessment of Adverse Events 
All AEs (non-serious and serious) spontaneously reported by the subject and/or in response to an 
open question from the study personnel or revealed by observation will be recorded and assessed 
during the study at the investigational site. 
Information about AEs will be collected from the signing of consent form until the end of the study. 
Even after completion of the study, the investigator shall notify Santen EMEA SV of any new SAEs 
that may be associated with the study drug. 
All non-serious AEs will be evaluated until recovery or until the last post-study visit/contact. The 
investigator must follow up subjects with a SAE with causal relationship to study treatment until it 

DE-130A (latanoprost 50 microg/ml eye drops emulsion, SD) Amendment1 Version 5.0 26 February 2021 
 
Confidential 
67 
 
has resolved, stabilized or a final assessment can otherwise be made. The same principle applies to 
all study drug -related AEs which can lead to early termination and AEs which are under special 
interest. 
The investigator will take appropriate and necessary therapeutic measures required for resolution of 
the AE. Any medication necessary for the treatment of a AE must be recorded. During the 
investigator-masked treatment period, the investigator should only unmask the treatment allocation 
if this is relevant to the safety of the subject. 
During the study, patients will also be allowed to use unpreserved artificial tears with the same dose 
regimen and frequency as before baseline. The events reported during the washout period with 
artificial tears are considered as AEs. After the first administration of the study drug, the events with 
causal relationship to the artificial tears are considered as AEs. The AEs with causal relationship to 
the artificial tears are also assessed, recorded and reported as described in the further section. 
12.2.2.1. Seriousness 
The seriousness of each AE must be assessed by the investigator according to the criteria set for 
SAEs in section 12.2.1.2. If the event does not meet the criteria of a SAE, it is assessed as non-
serious. 
12.2.2.2. Causality to Study Drug or Artificial Tears 
An investigator who is qualified in medicine must make the determination of causality to artificial 
tears for each AE during the washout period, and the causality assessment to the study drug and 
artificial tears, respectively, for AEs occurred during the treatment periods. The following categories 
shall be used:  
Related: There is a reasonable possibility that the AE may have been caused by the study drug 
or AT. 
Not related: There is no reasonable possibility that the AE may have been caused by the study 
drug or AT. 
The investigator should decide whether, in his or her medical judgment, there is a reasonable 
possibility that the event may have been caused by the study drug or artificial tears. If no valid reason 
exists for suggesting a relationship, then the AE should be classified as “unrelated.” If there is any 
valid reason, even if undetermined, for suspecting a possible cause-and-effect relationship between 
the study drug (or artificial tears) and the occurrence of the AE, then the AE should be considered 
“related”. 
The Sponsor should report serious adverse reactions with causal relationship to non-investigational 
medicinal product (artificial tears) to the MAH of the product (if not the Sponsor) or to the relevant 
competent authorities. 
12.2.3. 
Relationship to Study Procedures 
The relationship to study procedures (e.g., wash-out period) should be determined for AE using the 
following categories: 
Related: There is a reasonable possibility that an event may have been caused by a study 
procedure. 
Not Related: There is no reasonable possibility that an event may have been caused by a 
study procedure.

68 
 
12.2.3.1. 
Severity 
Severity will be assessed according to the following scale: 
 Mild: awareness of sign or symptom, but easily tolerated 
 Moderate: discomfort sufficient to cause interference with normal activities 
 Severe: incapacitating, with inability to perform normal activities 
It is important to distinguish between serious and severe AEs. Severity is a measure of intensity 
whereas seriousness is defined by the criteria under Section 12.2.1.2. An AE of severe intensity may 
not be considered serious. 
12.2.4. 
Expectedness 
AEs will be evaluated as to whether they are expected or unexpected. The assessment is performed 
by the Sponsor and in this study it is based on reference safety information (Investigator’s Brochure)  
 Expected: An AE is expected when the nature or severity of which is consistent with the 
applicable product information. 
 Unexpected: An AE is unexpected when the nature or severity of which is not consistent with 
the applicable product information. 
12.2.5. 
Reporting of Safety Information 
12.2.5.1. Reporting of Adverse Events 
All serious and non-serious AEs including non-serious AEs considered to be of special interest 
(CSIs) by sponsor (in Section 12.2.1.3), must be reported on the adverse event electronic case report 
form (AE eCRF). In addition, SAEs and non-serious AEs, which have been considered to be CSI, 
must be reported expeditedly to the sponsor (Section 12.2.4.3). 
For each AE, the investigator will evaluate and report  
 the event term (verbatim),  
 the onset date,  
 severity,  
 location (e.g. right/left eye, both eyes, or not applicable if non ocular event),  
 causality to study drug (for AEs only) and artificial tears,  
 relationship to study procedures,  
 action taken for study drug (for AEs only),  
 seriousness,  
 outcome of event 
 the end date, and  
 whether or not it caused the patient to discontinue the study. 
The AE term should be reported in standard medical terminology when possible.

If known, the diagnosis (i.e., disease or syndrome) must be recorded rather than component signs 
and symptoms (e.g., record as "worsening of cataract" rather than "drop in vision"). However, other 
events that are considered unrelated to an encountered syndrome or disease should be recorded as 
individual AEs (e.g., if worsening of macular edema and worsening of panuveitis are observed at the 
same time and are clinically unrelated, each event should be recorded as an individual AE). 
12.2.5.2. 
Reporting of Case of Special Interest and Pregnancy 
Other CSIs (non-serious AEs covered in the Section 12.2.1.3) or spontaneously reported pregnancy 
(Section 12.2.1.4) in a patient or in a partner to the patient must be recorded in the source documents 
at the investigation site and reported expeditedly to Santen EMEA SV (Section 12.2.4.3). 
Pregnancy in itself is not regarded as an AE unless there is a suspicion that an investigational product 
may have interfered with the effectiveness of a contraceptive medication. The pregnancy which 
occurs during the study or within 14 days of completing the study must be reported. 
The outcome of all pregnancies (spontaneous miscarriage, elective termination, normal birth or 
congenital abnormality) must be followed up and documented even if the patient was discontinued 
from the study presuming that the informed consent is obtained for this from the patient. The outcome 
(health of infant) must also be reported to the Santen EMEA SV. 
All reports of congenital abnormalities/birth defects are SAEs. Spontaneous miscarriages should also 
be reported and handled as SAEs. Elective abortions without complications should not be handled 
as AEs. 
12.2.5.3. 
Expedited reporting 
All SAE, CSI and Pregnancy reports must be reported to Santen EMEA SV immediately but no 
later than within 24 hours of the first awareness of the event. The investigator must complete, sign 
and date the SAE (or CSI/Pregnancy) pages, verify the accuracy of the information recorded on the 
SAE (or CSI/Pregnancy) pages, and send a copy by e-mail or fax to Santen EMEA SV: 
 
Santen EMEA, Safety Vigilance (SV) 
Email to safetyEU@santen.com or 
 Phone +358 3 284 8625 
 
The Sponsor records all SAE, CSI and Pregnancy reports in the safety database of Santen. 
Additional follow-up information, if required or available, should all be sent by e-mail or faxed to 
Santen EMEA SV immediately but no later than within 24 hours of receipt and this should be 
completed on a follow-up SAE (or CSI/Pregnancy) form and placed with the original information 
and kept with the appropriate section of the eCRF and/or study file. 
The Sponsor is responsible for ongoing safety evaluation of the study drug. If there is at least a 
reasonable possibility that the event is related to the study drug and it is both serious and unexpected 
(SUSAR), the sponsor shall initiate expedited reporting according to applicable reporting 
requirements to all relevant parties, including regulatory authorities, ethics committees and 
investigators. Reporting responsibilities are described in the study specific safety management plan.

12.2.5.4. Follow-up of Adverse Events 
All reported AEs should be followed until resolution or until the scheduled exit visit. A Subject 
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 CSIs (excluding medication errors or <other special situations(e.g. overdose)> 
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. 
The follow-up information on an individual SAE, AE or CSI 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, faxed 
or reported in writting to the appropriate Email/fax numbers or personnel identified in section 
12.2.4.3.   
 
 
12.2.6. 
Documentation of Safety Information 
All AEs will be recorded during the study in the subject’s medicinal records and on the appropriate 
AE eCRF at the investigational site. CSIs and Pregnancies will be recorded in the source documents. 
The Sponsor records all SAEs, CSIs and Pregnancy reports in the safety database of Santen.

STATISTICS 
13.1. 
General Considerations 
Unless specified otherwise, for Period 1 analyses, efficacy measures will be summarized by planned 
treatment on the FAS population, and safety measures will be summarized by actual treatment 
received on the Safety population. For Period 2, and Periods 1 & 2 combined analyses, both efficacy 
and safety measures will be summarized for DE-130A group on the Open-Label population. 
Continuous variables will be summarized using descriptive statistics such as number of observations 
(n), mean, standard deviation, medium, minimum, and maximum.  Categorical variables will be 
tabulated using frequency (n) and percent (%).  For the variables recorded for both eyes, the 
descriptions will be given separately for the study eye and for the fellow eye for all ocular safety 
measures. All efficacy analyses will only be performed on the study eye. 
All data manipulations and descriptive summaries will be performed using SAS Version 9.4 or later.  
The ICH guideline on case report tabulations will be followed.  A Statistical Analysis Plan (SAP) 
will be written and finalized before the start of the analysis of the study data, which will present the 
details of how all the analyses will be performed. 
Unless otherwise specified, all statistical testing will be done with Type I error rate of 0.05 (2-sided). 
13.1.1. 
Sample Size 
For the primary efficacy endpoint of change from baseline in peak IOP and trough IOP, separately, 
at Week 12 visit, sample size calculation was based on data obtained from the phase II study 
(NVG10E118). 
Sample size was thus calculated assuming a mean difference in IOP change from baseline of 0 mmHg 
and a common standard deviation of 4.26 mmHg in the peak or trough IOPs, respectively, for the 
comparison between the DE-130A and the control (Xalatan®) groups. A total sample size of 
approximately 380 subjects (190 per treatment arm) will provide 90% power to demonstrate the non-
inferiority of the DE-130A group to the control group (one-sided α = 0.025) for non-inferiority 
margin of 1.5 mmHg, assuming 10% dropout rate. 
13.1.2. 
Study Eye 
Data collection will be done on both eyes, however, efficacy analyses will only be performed on the 
study eye. 
The study eye is defined as the eye that qualifies per inclusion / exclusion criteria at the Baseline 
Visit. If both eyes are eligible, the eye with the higher IOP at the Baseline Visit will be chosen. If 
both eyes have the same IOP value at Baseline, the eye with the higher CFS score at the Baseline 
Visit will be chosen. If both eyes have the same IOP and CFS values, then the right eye will be 
designated as the study eye. 
13.1.3. 
Multiple Comparisons/Multiplicity 
To control the overall type I error rate at 0.05 level, the three hypotheses testing in the primary and 
key sencondary endpoints will be performed sequentially according to hierarchical fixed sequence 
procedure below:

1. Hypothesis testing of non-inferiority of DE-130A to Xalatan® for the primary endpoint: 
change from baseline in peak (9:00 am ± 1 hour) and trough (4:00 pm ± 1 hour) IOPs, 
respectively, at Week 12. 
2. Hypothesis testing of superiority of DE-130A to Xalatan® for the first key secondary 
endpoint: change from baseline in CFS score at Week 12 in subjects with baseline CFS ≥ 1. 
3. Hypothesis testing of superiority of DE-130A to Xalatan® for the second key secondary 
endpoint: change from baseline in symptom score (average of 3 symptoms: dry eye sensation, 
blurred/poor vision and burning/stinging/itching) at Week 12 in subjects with baseline 
symptom average score >0. 
 
13.2. 
Analysis Populations 
The following analysis populations are considered: 
 The Full Analysis Set (FAS) population consists of all randomised subjects who received at 
least one dose of the study medication and provided at least one post-baseline IOP 
measurement at peak and trough timepoints, separately. The FAS population will be the 
analysis population for  all efficacy endpoints in Period 1 and will use treatment as 
randomised. 
 The Safety population consists of all subjects randomised in the study who received at least 
one dose of the study medication. The Safety population will be the analysis population for 
all safety analyses in Period 1 and will use treatment as actually received. 
 The Glaucoma/OHT Per-Protocol (PP) population will be a subset of the FAS subjects. It 
includes all FAS subjects without any of the major protocol deviations that could affect the 
primary efficacy endpoint. The PP population will be used for sensitivity analyses of the 
primary efficacy endpoints in Period 1 and will use treatment as randomised.  
 The Ocular Surface Disease Per-Protocol (PP) population will be a subset of the FAS 
subjects. It includes all FAS subjects without any of the major protocol deviations that could 
affect the key secondary endpoints. This population will be used for sensitivity analyses of 
the key secondary endpoints in Period 1 and will use treatment as randomised. 
 The Open-Label Population will be a subset of the FAS subjects whocomplete their Week 
12 Visit and agree to participate in the open-label period of the study, and received at least 
one dose of the study medication during the open-label period and provided at least one 
morning IOP measurement after the Week 12 Visit. This population will be the analysis 
population for the analyses of efficacy endpoints in Period 2 and for Periods 1 & 2 combined 
data and will use treatment as randomised. 
 The Open-Label Safety population will be a subset of the FAS subjects who complete their 
Week 12 Visit and agree to participate in the open-label period of the study, and received at 
least one dose of the study medication during the open-label period. The Open-Label Safety 
population will be the analysis population for all safety analyses in Period 2 and for Periods 
1 & 2 combined data and will use treatment as actually received.

13.3. 
Analysis of Demographics and Baseline Characteristics 
Descriptive summaries will be performed for demographic (including age, gender, race, ethnicity, 
female patients’ menopausal status) and baseline characteristics variables (including time since 
diagnosis and past surgery or laser treatment in the study eye, and smoking status).  
In addition, medical history (ocular and systemic), and prior and concomitant medication uses will 
be summarized by treatment groups for the overall FAS population, Safety population, Open-label 
population, separately. In addition, medical history (ocular and systemic) and prior and 
concomitant medication use will be summarized by treatment group for the overall FAS 
population. Prior medication is defined as any medication that was used by the patients that is 
discontinued before the Baseline Visit (Day 1).  
13.4. 
Efficacy analyses 
During period 1, if a patient takes any concomitant medications or undergoes any concomitant 
therapies listed in Section 8.2 of this protocol, IOP and/or CFS and OSD symptom scores after 
taking the medication/therapy will be censored for the primary and/or key secondary efficacy 
endpoints analyses. The endpoint(s) that will be censored depends on the medications or therapies 
taken, which will be determined by the Sponsor team during the masked data review before database 
lock.   
 IOP data will be censored after any IOP-lowering medication/therapy is taken.  
 CFS and symptom scores will be censored after any medication (including artificial tears 
change)/therapy that might have any effect on the OSD signs and symptoms.  
If it is determined that a medication or therapy could have an effect on both IOP and OSD endpoints, 
IOP, CFS and symptom scores will all be censored. 
 
13.4.1. 
Analysis of Primary Efficacy Endpoint 
The analysis of primary efficacy endpoint will be performed on the FAS population. 
The difference in change from baseline in peak and trough IOP between the DE-130A group 
and the Xalatan® group at the Week 12 Visit in the IOP study eye will be compared using a  
mixed-effects model for repeated measures (MMRM) on observed cases collected up to Week 
12 based on FAS population. A separate MMRM model will be used for IOP at peak and 
trough, respectively. The model will include treatment, visit, treatment-by-visit interaction and 
country as fixed effects, baseline IOP at the respective timepoint (peak or trough) as covariates.  
The 95% confidence intervals intervals and p-values will be reported.  
For the primary efficacy endpoint, the following hypotheses will be tested: 
 
H0: µT  – µC > Δ for at least one 
timepoint  
versus  
HA: µT  – µC ≤ Δ for both timepoints 
 
where µT and µC denote the mean change from baseline in peak or trough IOP in DE-130A and 
Xalatan® groups, respectively, and Δ denotes the non-inferiority margin of 1.5 mmHg. Non-
inferiority will be established if the upper limit of the one-sided 97.5% confidence interval is less 

DE-130A (latanoprost 50 microg/ml eye drops emulsion, SD) Amendment1 Version 5.0 26 February 2021 
 
Confidential 
74 
 
than or equal to the non-inferiority margin of 1.5 mmHg at both the peak and trough timepoints at 
Week 12. 
Sensitivity analysis of the primary efficacy endpoints will be done with the Glaucoma/OHT PP 
population.  
Because both the peak and trough IOP endpoints have to meet the non-inferiority criterion in order 
to claim non-inferiority of DE-130A as compared to Xalatan®, no multiplicity adjustment is needed 
for the primary efficacy endpoint. 
13.4.2. 
Analysis of Secondary Efficacy Endpoints 
13.4.2.1. Analysis of the Key Secondary Endpoints 
The key secondary endpoints are: 
 Change from baseline in CFS score in the study eye at Week 12 in patients with baseline 
CFS ≥ 1 
 Change from baseline in OSD symptom score (average of 3-symptom: dry eye sensation, 
blurred/poor vision and burning/stinging/itching) in the study eye at Week 12 in patients 
with baseline symptom average score >0 
 
If non-inferiority in the primary endpoint is achieved, the above two key secondary endpoints will 
be tested for superiority, sequentially according to hierarchical fixed procedure: 
1) Change from baseline in CFS score at Week 12 in subjects with baseline CFS ≥ 1 
 
The MMRM model with a similar model setting described for the analysis of the primary efficacy 
endpoint will be used to test the following hypotheses: 
H0S1: µTs1 – µCs1  = 0  
versus  
HAS1: µTs1– µCs1 ≠ 0 
where µTs1 and µCs1 denote the mean change from baseline in CFS in DE-130A and Xalatan® 
groups, respectively. 
If the hypothesis is rejected at 0.05 significance level, then the following key secondary endpoint 
will be tested. 
2) Change from baseline in symptom score (3-symptom average) at Week 12 in subjects with 
baseline symptom score >0 
The MMRM model with a similar model setting described for the analysis of the primary efficacy 
endpoint will be used to test the following hypotheses: 
H0S2: µTs2 – µCs2  = 0 
versus 
HAS2: µTs2 – µCs2 ≠ 0 
where µTs2 and µCs2 denote the mean change from baseline in symptom score (3-symptom average) 
in DE-130A and Xalatan® groups, respectively.

The Ocular Surface Disease PP population will be used for the sensitivity analysis of the two key 
secondary efficacy endpoints. 
13.4.2.2. Analysis of the Other Secondary Endpoints 
Ocular Surface Disease Assessments 
Change from baseline in conjunctival fluorescein staining, TFBUT, and each individual symptom 
score in the study eye at each analysis visit in Period 1 will be compared between treatment groups 
using MMRM on observed cases. More details on the model specifications will be provided in the 
SAP. 
Percentage of patients with conjunctival hyperemia (measured by slit lamp scored using the 
photographic scale derived from McMonnies scale [1 to 6)) in the study eye at each analysis visit in 
Period 1 will be compared between treatment groups using a Chi-squared test or Fisher’s Exact test 
wherever appropriate for the FAS population. 
CFS, corneal and conjunctival fluorescein staining, TFBUT, 3-symptom average and individual 
symptom score, and slit lamp examination in the study eye at each analysis visit will be 
summarized descriptively by treatment group. 
Artificial tears use during Period 1 will be summarised by treatment group as a continuous variable 
as well as by percentage of patients who use artificial tears at each analysis visit. 
Descriptive statistics will also be provided for ocular surface disease endpoints (corneal and 
conjunctival fluorescein staining, TFBUT, symptom scores [3-symptom average and individual 
symptom score]) and their change from baseline at each visit by analysis visit and treatment group 
in Period 1 only. 
For the patients participating to the safety follow-up, OSD endpoints and their change from 
baseline will be summarized for subjects within the Open-Label population by analysis visit for the 
whole study period (Periods 1 & 2) and change from Week 12 for Period 2. 
IOP Assessments 
Changes in peak, trough, and mean diurnal IOPs on the study eye will be summarized by treatment 
group at Week 4 and Week 12. 
Peak, trough, and mean diurnal IOP responses on the study eye (IOP 20%, 25%, 30% responses, and 
IOP < 18 mmHg response, defined in Section 5.3.3) will be summarized by treatment group at Week 
4 and Week 12. 
Quality of life Assessements 
Mean scores of quality of life (Glaucoma Quality of Life-15), and their change from baseline (Period

Subjects Global Rating of Treatment 
Subjects global rating of treatment at Week 12/early termination will be summarized by treatment 
groups for the FAS population. Also, it will be summarized at Month 15/early termination for the 
Open-Label Population.  
 
13.5. 
Analysis of Safety and Tolerability Endpoints 
Safety and tolerability endpoints will be summarized for the following three time periods:  
 Period 1 (Day 1 to Week 12 Visit): for whole Safety population by treatment group  
 Period 2 (Week 12 Visit to Month 15 Visit/early termination): for all subjects who entered 
into the open-label period (Open-Label Safety population) 
 Entire study period (Day 1 to Month 15/early termination): for all subjects who entered into 
the open-label period (Open-Label Safety population).  
13.5.1. 
Adverse Events 
An adverse event is treatment-emergent (TEAE) if it occurs or worsens after the first dose of study 
treatment. A suspected adverse reaction (SAR) is any adverse event for which there is a reasonable 
possibility that the study drug, study procedure or artificial tears caused the adverse event. 
Adverse events will be coded using the MedDRA dictionary. Frequencies and percentages will be 
given as follows:  1) Overall summary; 2) by system organ class and preferred term, 3) by system 
organ class, preferred term and maximal severity, 4) by system organ class, preferred term and 
relationship to study medication and study procedure, respectively, and 5) by system organ class, 
preferred term, maximal severity, and relationship to study medication and study procedure, 
respectively.  
Separate analyses will be performed for AEs, SARs, SAEs, serious SARs, and for ocular and non-
ocular events. Ocular events will be summarized for the study eye and the fellow eye separately. 
13.5.2. 
Other Safety Assessments 
Other safety assessment parameters (e.g. slit lamp examination, dilated fundoscopy, BCDVA, and 
visual field) will be summarized by study period, analysis visit and treatment group (Period 1 only). 
They will be summarized for the study eye and the fellow eye separately. Pregnancy test results will 
be provided in a listing. 
13.6. 
Interim Analysis 
There is no planned interim analysis for this study. 
13.7. 
Handling of Missing Values 
Missing data will be handled within the MMRM model for all efficacy assessment analysed using 
this statistical model. 
No missing data on safety endpoints will be imputed.

For medical events including AEs, completely or partially missing onset and resolution dates will 
be imputed in a conservative fashion to be detailed in the Statistical Analysis Plan (SAP).  
Likewise, rules will be applied 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 the handling of missing data will be provided in the SAP.

DIRECT ACCESS TO SOURCE DATA/DOCUMENTS 
14.1. 
Study Monitoring 
Before an investigational site can enter a patient into the clinical study, a representative of the 
Sponsor will visit the investigational study site to: 
 Determine the adequacy of the facilities. 
 Discuss with the investigator(s) and other personnel their responsibilities with regard to 
protocol adherence, and the responsibilities of Santen or its representatives.  This will be 
documented in a Clinical Study Agreement between Santen or its designee and the 
investigator. 
During the study, a monitor from Santen or representative will have regular contacts with the 
investigational site, for the following: 
 Provide information and support to the investigator(s). 
 Confirm that facilities remain acceptable. 
 Confirm that the investigational team is adhering to the protocol, that data are being 
accurately recorded in the case report forms, and that investigational product accountability 
checks are being performed. 
 Perform source data verification.  This includes a comparison of the data in the case report 
forms with the patient’s medical records at the hospital or practice, and other records relevant 
to the study.  This will require direct access to all original records for each patient (e.g. clinic 
charts). 
 Record and report any protocol deviations not previously sent to Santen. 
 Confirm non-serious AEs and SAEs have been properly documented on eCRFs and confirm 
any safety information requiring expedited reporting to Santen EMEA SV (including SAEs, 
CSIs and Pregnancies) have been forwarded to Santen and those SAEs that met criteria for 
reporting have been forwarded to the IRB. 
The monitor will be available between visits if the investigator(s) or other staff needs information 
or advice. 
14.2. 
Audits and Inspections 
Authorized representatives of Santen, a regulatory authority (national or foreign), an Independent 
Ethics Committee or an Institutional Review Board may visit the site to perform audits or inspections, 
including source data verification.  The purpose of an audit or inspection is to systematically and 
independently examine all study-related activities and documents to determine whether these 
activities were conducted, and data were recorded, analyzed, and accurately reported according to 
the protocol, Good Clinical Practice guidelines of the International Conference on Harmonization, 
and any applicable regulatory requirements.  The investigator should contact Santen immediately if 
contacted by a regulatory agency about an inspection.

Appendix A-IV  Intraocular Pressure measurement  
 
Using the Goldmann applanation tonometry 
 
IOP will be performed at each visit.  
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.  
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 (oxybuprocaine 0.4%) one drop of 
fluorescein 2% may be instilled.  
 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. 
 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.

Appendix E 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 
48th WMA General Assembly, Somerset West, Republic of South Africa, October 1996 
52nd WMA General Assembly, Edinburgh, Scotland, October 2000  
53rd WMA General Assembly, Washington DC, USA, October 2002 (Note of Clarification added) 
55th WMA General Assembly, Tokyo, Japan, October 2004 (Note of Clarification added) 
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. 
7.         Medical research is subject to ethical standards that promote and ensure respect for all human 
subjects and protect their health and rights.

Study 0130A01SA 
 
 
 
Confidential 
104 
 
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 minimises 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 minimise the risks must be implemented. The risks must be continuously monitored, 
assessed and documented by the researcher.  
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

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 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 authorised 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 authorised representative. The potential subject’s dissent should be respected. 
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 authorised 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 authorised 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.

107 
 
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. 
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 authorised representative, may use an unproven intervention if in the 
physician's judgement 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.

If historical visual fields are not available 
within the last 18 months prior to screening, 
but at least two OCTs (optical coherence

last 6 months and are stable, the patient can be 
enrolled in the study if a visual field test is also 
performed at screening and shows no defect or 
only an early visual field loss in either eye 
(mean deviation lesser than -6 dB).

Subject Inclusion Criteria 
 
 
The following wording was added do define that 
the washout period after discontinuation of a 
treatment may vary between individuals. The 
protocol specifies that Post-washout IOP should 
be measured 5 to 7 days after stopping 
Brinzolamide as this timeframe is considered in 
many clinical trials. However it is possible that 
for some patients, some additional days may be 
necessary before the drug is considered washed 
out. In addition the patient is not at risk when 
receiving no treatment for a few more days 
given  the IOP is in the normal range (ie. <22 
mmHg) and the patient is closely monitored. 
Therefore, the time for IOP measurement after 
Brinzolamide discontinuation can be extended 
up to 6 additional days: 
 
If IOP is <22 mmHg, the wash-out period can 
be extended and the IOP should be re-assessed 
two to three days after the first measurement. If 
the IOP is still < 22 mmHg at the second 
measurement, a third assessment should be 
performed two to three days after the second 
measurement. If the IOP is still < 22 mmHg at 
the third  measurement, the patient cannot be 
randomized in the study.

Analysis of Primary and 
Key Secondary Efficacy 
Endpoints 
 
The primary efficacy endpoint is the change 
from baseline in peak and trough IOP, 
respectively, between the DE-130A group and 
the Xalatan® group in the study eye at Week 12. 
Statistical analysis will be performed using a  
mixed-effects model for repeated measures 
(MMRM) on observed cases collected up to 
Week 12 based on FAS population. A separate 
MMRM model will be performed for IOP at 
peak and trough, respectively. The model will 
include treatment, visit, treatment-by-visit 
interaction and country as fixed effects, 
baseline IOP at the respective timepoint (peak 
or trough) as covariates. Non-inferiority will be 
established if the upper limit of the one-sided 
97.5% confidence interval from the 
independent-sample Student’s t-test for the 
difference between DE-130A and Xalatan® in 
change from baseline peak and trough IOP, 
respectively, at Week 12 is less than or equal to 
the non-inferiority margin of 1.5 mmHg at both 
the peak and trough timepoints at Week 12. 
Superiority is achieved with respect to this 
endpoint if the upper limit of the one-sided 
97.5% confidence interval is < 0 mmHg for 
both timepoints at Week 12.  
 If non-inferiority in the primary endpoint is 
achieved, the two key secondary endpoints will 
be tested for superiority, sequentially according 
to hierarchical fixed sequence procedure. 
MMRM models will be fitted for each key 
secondary endpoint using a similar model 
setting as described for the analysis of the 
primary efficacy endpoint  Fixed sequence 
procedure will be applied to control the overall

Rationale for the 
Proposed Study 
 
 
The following wording has been deleted or 
added in order to optimize the statistical analyses 
part: 
In the proposed non-inferiority study, to 
approximate the peak and trough times, the IOP 
will be measured at 9:00 (±1 hour) am and 4:00 
(±1 hour) pm, and the diurnal mean will be 
used to assess the primary efficacy endpoint and 
secondary endpoints during a 3-month period 
with randomised investigator-masked 
medication. The chosen non-inferiority margin 
of 1.5 mmHg is well below (Musch, 2006 the

effect of the active control (−8.6±2.6 mmHg, 
Rouland, 2013 (45)). In addition to the 
comparison of peak, trough, and mean diurnal 
IOP, the rates of different responders (defined by 
a reduction in mean IOP of ≥ 20%, ≥ 25%, and ≥ 
30%, and a mean IOP < 18mm Hg) will be 
compared between treatment groups.  
Regarding the OSD, the potential positive 
impact of the cationic formulation of DE-130A 
on OSD signs (using TFBUT, slit lamp 
examination, corneal, and conjunctival 
fluorescein staining with modified Oxford scale) 
and symptoms (using 3-symptom assessment 
and artificial tears use) will be compared with 
the effect on OSD of the BAK-preserved 
Xalatan®. Furthermore the quality of life impact 
will also be compared between treatment groups. 
However in order to provide long-term 
additional data on the safety and tolerability of 
DE-130A, a 12-month follow-up with open-label 
DE-130A is to be offered up to the first 130 
patients (whatever their randomised treatment is) 
who complete their Week 12 Visit and agree to 
participate in the open-label period of the study. 
During this safety follow-up, only the peak IOP 
will be measured in order to minimize patients’ 
burden.

-CFS score of 1, 2, or 3 (Modified Oxford scale) 
-At 
least 
one 
of 
the 
symptom

where µT and µC denote the mean change from 
baseline in peak or trough IOP in DE-130A and 
Xalatan® groups, respectively, and Δ denotes the non-
inferiority margin of 1.5 mmHg.  Non-inferiority will 
be established if the upper limit of the one-sided 97.5% 
confidence interval is less than or equal to the non-
inferiority margin of 1.5 mmHg at both the peak and 
trough timepoints at Week 12. 
Sensitivity analysis of the primary efficacy endpoints 
will be done with the Glaucoma/OHT PP population 
and with the observed cases only.  
Because both the peak and trough IOP endpoints have 
to meet the non-inferiority criterion in order to claim 
non-inferiority of DE-130A as compared to Xalatan®, 
no multiplicity adjustment is needed for the primary 
efficacy endpoint.

Week 4 and Week 12, respectively, for the FAS 
population and CFS subgroups. 
Peak, trough, and mean diurnal IOP responses 
(IOP 20%, 25%, 30% responses, and IOP < 18 
mmHg response, defined in Section 5.3.3) will 
be summarized by treatment groups at Week 4 
and Week 12, respectively, for the FAS 
population and CFS subgroups. 
For patients participating to the safety follow-
up, change from baseline and change from 
Week 12, respectively, in mean morning (9:00 
am ± 1 hour) IOP will be summarized for the 
Open-Label population and for CFS subgroups 
at Month 6, Month 9 and Month 15/early 
termination. 
Ocular surface disease Assessments 
 
Change from baseline in each 
individual symptom score, and TFBUT 
at Week 12 will be compared between 
treatment groups using an 
independent-sample Student’s t-test for 
the FAS population and for CFS 
subgroups, respectively.   
 
Percentage of patients with moderate 
and severe conjunctival hyperemia 
(grade ≥ 3 measured by slit lamp scored 
using the photographic scale derived 
from McMonnies scale (1 to 6)) at 
Week 12 will be compared between 
treatment groups.  
 
Proportion of subjects using artificial 
tears at Week 12 will also be compared 
between treatment group using a Chi-
squared test or Fisher’s Exact test 
wherever appropriate for the FAS 
population and for CFS subgroups, 
respectively. 
Ocular surface disease endpoints (corneal and 
conjunctival fluorescein staining [modified 
Oxford scale], TFBUT, symptom scores [3-
symptom average and individual symptom 
score], use of artificial tears [continuous 
variable], and slit lamp examination) and their 
change from baseline at each visit will be 
summarized for the FAS population and for

CFS subgroups, respectively, by treatment 
group (Period 1) and by analysis visit. 
Artificial tears use during Period 1 (Day 1 to 
Week 12 Visit) will also be analyzed by 
treatment group on percentage of patients who 
use artificial tears at each visit. 
For the patients participating to the safety 
follow-up, OSD endpoints and their change 
from baseline will be summarized for the Open-
Label population and for CFS subgroups by 
analysis visit for the whole study (Periods 1 & 
2) and change from Week 12 for Period 2. 
Quality of life Assessments 
Mean scores of quality of life (Glaucoma Quality of 
Life-15), and their change from baseline (Period 1 and 
Periods 1 & 2) and change from Week 12 (Period 2) 
will be summarized by study period,  analysis visit and 
by treatment group (Period 1), for the FAS population 
(Period 1), for the Open-Label Population (Period 2, 
Periods 1 & 2)., and for CFS subgroups. 
Subjects Global Rating of Treatment 
Subjects global rating of treatment at Week 12/early 
termination will be summarized by treatment groups 
for the FAS population and for CFS subgroups, 
respectively. Also, it will be summarized at Month 
15/early termination for the Open-Label Population.

Adverse Events 
 
 
The following wording has been deleted or 
added in order to optimize the statistical analyses 
part: 
A suspected adverse reaction (SAR) is any adverse 
event for which there is a reasonable possibility that 
the study drug or study procedure or artificial tears 
caused the adverse event.

Protocol  
Other Safety 
Assessments 
 
The following wording has been added in order 
to optimize the statistical analyses part: 
Other safety assessment parameters (e.g. slit lamp 
examination, dilated fundoscopy, BCDVA, and visual 
field) will be summarized by study period, analysis 
visit and treatment group (Period 1 only).

Handling of Missing 
Values 
 
 
The following wording has been deleted or 
added in order to optimize the statistical analyses 
part: 
 
Missing data will be handled within the 
MMRM model for all efficacy assessment 
analysed using this statistical model. 
No missing data on safety endpoints will be 
imputed. 
subjects whose IOP, or CFS/symptom score 
data got censored due to the usage of 
prohibited medications/therapies, their 
censored data after being rescued will be 
imputed using a last-observation-carried-
forward approach (LOCF). For missing IOP 
measures, IOP values taken at the same time 
point (peak or trough) at the last visit prior to 
being rescued will be used for the imputation. 
If during Period 1, a subject has missing data 
but not taking any concomitant medications or 
therapies that has IOP-lowering or OSD sign 
and/or symptom improving effect, the LOCF 
approach will be used to impute the missing 
data on IOP, CFS, or symptom scores (3-
symptom average).  For peak or trough IOP, 
the last observation at peak or trough, 
respectively, will be carried forward. Missing 
data will be only imputed for the primary and 
key secondary efficacy endpoints analyses. 
For medical events including AEs, completely or 
partially missing onset and resolution dates will be 
imputed in a conservative fashion to be detailed in the 
Statistical Analysis Plan (SAP).  Same Likewise 
rules will be applied followed to impute the 
completely or partially missing start and end dates of 
non-study medications.
