STUDY OUTLINE / PROTOCOL SYNOPSIS 
 
Title 
A Phase 3, Randomized, Adaptive Dose-Selection, Multi-Regional, Double-
Masked, Parallel-Group, 3–Month Trial Evaluating the Safety and Efficacy of 
NCX 470 vs. Latanoprost 0.005% in Subjects with Open-Angle Glaucoma or Ocular 
Hypertension (Mont Blanc) 
Study No. 
NCX-470-02 
Sponsor 
Nicox Ophthalmics, Inc. 
Background 
and Rationale  
Glaucoma is a leading cause of blindness worldwide (Jonas, 2017).  Intraocular 
pressure (IOP) is the primary risk factor for glaucoma, and lowering IOP to prevent 
optic nerve injury is currently the only proven effective treatment (Jonas, 2017).  
Topical prostaglandin analogs (PGAs), such as latanoprost, bimatoprost, and 
travoprost, are the most common first-line therapies used to lower IOP in glaucoma 
patients (Daka, 2014). 
Nicox is developing NCX 470, a nitric oxide (NO)-donating bimatoprost 
prostaglandin analog, as a new therapy for lowering of IOP in patients with open-
angle glaucoma (OAG) or ocular hypertension (OHT). When exposed to esterases 
in the eye, NCX 470 is cleaved into the prostamide bimatoprost, which in turn is 
converted to bimatoprost acid, a prostaglandin F2α receptor agonist, and into 6-
(nitrooxy)-hexanoic acid, a NO-donating moiety.   
Nitric oxide relaxes the trabecular meshwork (TM) and increases outflow of the 
aqueous humor through the primary outflow mechanism from the anterior chamber 
(Gabelt, 2011; Heyne, 2013; Cavet, 2014).  In an additive manner, bimatoprost acts 
by increasing the outflow of aqueous humor primarily through the uveoscleral 
pathway (Krauss, 2004).   
The additive effect of a NO-donor and a prostaglandin F2α receptor agonist has 
been established in clinical trials with latanoprostene bunod, a dual-acting single 
molecular entity with NO-donating moiety linked to latanoprost. Latanoprostene 
bunod ophthalmic solution, 0.024% (VYZULTA®) was developed for the reduction 
of IOP in patients with OAG or OHT (Medeiros, 2016; Weinreb, 2016). In addition 
to the clinical validation of this approach, extensive nonclinical studies for both 
NCX 470 and latanoprostene bunod support this dual mechanism of action of NO-
donating PGAs for increased outflow via TM and uveoscleral pathways. 
The results of the Phase 2 trial “Dolomites”, NCX-470-17001 demonstrated that all 
tested concentrations of NCX 470 (0.021%, 0.042%, and 0.065%) once daily (QD) 
met the primary efficacy endpoint of non-inferiority to latanoprost 0.005% QD for 
reduction from baseline in mean diurnal IOP at Day 28. In pre-specified secondary 
efficacy analyses, NCX 470 0.065% was superior to latanoprost for mean IOP 
reduction from baseline at all 3 time points (8AM, 10AM and 4PM) on Day 28, with 
the difference reaching up to 1.4 mmHg. Mean IOP reduction from baseline at the 
3 time points across Days 7, 14 and 28 ranged from 7.6 to 9.8 mmHg for 
NCX 470 0.065% compared with 6.3 to 8.8 mmHg for latanoprost. Additionally, all 
three concentrations of NCX 470 were well tolerated. The most frequent adverse 
event was conjunctival hyperemia. There were no treatment-related serious 
adverse events, and no evidence of treatment-related systemic side effects. 
NCX 470 showed increased IOP-lowering efficacy with each incremental 
concentration of NCX 470, with a conjunctival hyperemia dose-response which 
plateaued at the middle dose (0.042%). The separation of the dose-response 

NCX-470-02 version 2.0; 08-July-2020 
 
Page 14 of 78 
curves in IOP lowering vs. conjunctival hyperemia showed a favorable therapeutic 
index thereby allowing for a higher concentration of NCX 470 (i.e., 0.1%) to be 
evaluated in this trial alongside the highest dose tested (0.065% NCX 470) in the 
Phase 2 Dolomites trial. An adaptive design will be utilized wherein one of the 
NCX 470 doses will be discontinued during the adaptive evaluation, which will occur 
after at least 30 randomized subjects in each arm complete their Week 2 Visit.

Objectives  
The primary objective is to demonstrate that NCX 470 (0.065% or 0.1%) QD is non-
inferior to latanoprost 0.005% QD based on mean IOP reduction from time-matched 
baseline at the 8AM and 4PM time points at the Week 2, Week 6 and Month 3 Visits. 
A secondary objective is to demonstrate that NCX 470 QD is superior to latanoprost 
0.005% QD based on mean IOP reduction from time-matched baseline at the 8AM 
and 4PM time points at the Week 2, Week 6 and Month 3 Visits. 
Another secondary objective is to demonstrate that NCX 470 (0.065% or 0.1%) QD 
is safe and well tolerated when administered to subjects for 3 months.

1. INTRODUCTION 
1.1 
Background and Rationale 
Glaucoma is a leading cause of blindness worldwide (Jonas, 2017).  Globally it has been 
estimated that 57.5 million people were affected by primary open-angle glaucoma (POAG) 
in 2015, with this number projected to rise to 65.5 million by 2020 (Kapetanakis, 2016).  
Intraocular pressure (IOP) is the primary risk factor for glaucoma, and lowering IOP to 
prevent optic nerve injury is currently the only proven effective treatment (Jonas, 2017).  
Topical PGAs, such as bimatoprost, are considered as the mainstay of treatment due to their 
efficacy and safety in lowering IOP (Daka, 2014).  Clinical trials reported greater reduction in 
IOP in subjects with OAG or OHT with bimatoprost 0.03% compared with either travoprost 
0.004% or latanoprost 0.005% in some instances, and equivalence among the three 
treatments in others (Parrish, 2003; Gandolfi, 2001).  All treatments presented an acceptable 
safety profile although lower incidences of conjunctival hyperemia have been reported with 
latanoprost 0.005% than with the other PGAs (Canadian Agency for Drugs and Technologies 
in Health, 2015; Daka, 2014). 
Nicox is developing NCX 470, a nitric oxide (NO)-donating bimatoprost prostaglandin analog, 
as a new therapy for lowering IOP in patients with OAG or OHT. When exposed to esterases 
in the eye, NCX 470 is cleaved into its active metabolites, the prostamide bimatoprost, which 
in turn is converted to bimatoprost acid, a prostaglandin F2α receptor agonist, and into 6-
(nitrooxy)-hexanoic acid, a NO-donating moiety. The active metabolites of NCX 470 include 
bimatoprost, the active ingredient in LUMIGAN®, (NDAs 021275 and 022184), and 6-
(nitrooxy)-hexanoic acid which leads to the release of NO. Another NO-donating PGA 
(VYZULTA®, latanoprostene bunod ophthalmic solution, 0.024%), also discovered and 
invented by Nicox, received US FDA (Food and Drug Administration) approval in November 
2017 for the reduction of IOP in patients with OAG or OHT (NDA 207795). 
Bimatoprost and NO provide robust IOP-lowering activity by concomitantly activating two 
independent mechanisms: uveoscleral outflow and trabecular/Schlemm’s canal conventional 
outflow facilities (Woodward, 2010; Cavet, 2014). Nitric oxide donors relax the TM and 
increase aqueous humor outflow (Gabelt, 2011; Heyne, 2013; Cavet, 2014).  As a result, NO 
modulates IOP through the conventional pathway.  In contrast, bimatoprost acts by 
increasing the outflow of aqueous humor primarily through the uveoscleral pathway (Krauss, 
2004). 
The additive effect of a NO donor and a prostaglandin F2α receptor agonist has been 
confirmed with latanoprostene bunod, a dual-acting NO-donating latanoprost developed for 
the reduction of IOP in patients with OAG or OHT (Medeiros, 2016; Weinreb, 2016).  This 
approach is supported by the nonclinical data package compiled for NCX 470, as well as the 
publicly available data for bimatoprost. 
NCX 470 exhibited potent and effective IOP-lowering activity in three ocular hypertensive 
animal models (Impagnatiello, 2015). Nonclinical pharmacology studies in well-established 
animal models of glaucoma and OHT have demonstrated that the IOP-lowering efficacy of 
NCX 470 is greater than that of equimolar doses of bimatoprost.  In particular, in transient 
ocular hypertensive rabbits, known to respond poorly to PGF2α analogs and prostamides, 
NCX 470 lowers IOP likely via NO release.  Additionally, an equimolar dose of NCX 470 at 
0.042% lowers IOP more effectively than bimatoprost at 0.03% in ocular normotensive dogs 
at 12 hours post dose, as well as in laser-induced ocular hypertensive non-human primates.  
The results of the first-in-man Phase 2 trial “Dolomites”, NCX-470-17001 demonstrated that 
all tested concentrations of NCX 470 (0.021%, 0.042%, and 0.065%) QD met the primary

Page 24 of 78 
efficacy endpoint of non-inferiority to latanoprost 0.005% QD for reduction from baseline in 
mean diurnal IOP at Day 28. In pre-specified secondary efficacy analyses, NCX 470 0.065% 
was superior to latanoprost for mean IOP reduction from baseline at all 3 time points (8AM, 
10AM and 4PM) on Day 28, with the difference reaching up to 1.4 mmHg. Mean IOP 
reduction from baseline at the 3 time points across Days 7, 14 and 28 ranged from 7.6 to 9.8 
mmHg for NCX 470 0.065% compared with 6.3 to 8.8 mmHg for latanoprost.  Additionally, 
all 3 concentrations of NCX 470 were well tolerated. The most frequent adverse event was 
conjunctival hyperemia. There were no treatment-related serious adverse events, and no 
evidence of treatment-related systemic side effects. The linearly increasing, dose-dependent 
IOP-lowering efficacy of NCX 470 without reaching a plateau, and the plateauing of ocular 
adverse events at the mid-dose of NCX 470 (0.042%) in the Phase 2 Dolomites trial (NCX-
470-17001) indicated that a higher dose (0.1%) has the potential for greater IOP lowering 
without apparent significant additional risks. Therefore, an adaptive design will be utilized in 
the current trial whereby one of the NCX 470 doses (0.065% or 0.1%) will be discontinued 
during the adaptive evaluation, which will occur after at least 30 subjects randomized in each 
arm complete their Week 2 Visit.

Description of Active Comparator 
 
Justification of the Study Design  
The proposed Phase 3 is a randomized, multi-regional, double-masked, parallel groups, 
active comparator-controlled clinical trial with adaptive dose selection.  
During the initial adaptive design dose-ranging phase, at least 30 subjects will be randomized 
in each arm in a 1:1:1 ratio to receive NCX 470 ophthalmic solution (0.065% or 0.1%), or 
latanoprost ophthalmic solution, 0.005% QD in the evening, one drop in each eye.

Justification of the Route of Delivery 
The topical ophthalmic route of delivery selected for the NCX 470 is the same as for the 
topical ophthalmic IOP-lowering product VYZULTA. NCX 470 and VYZULTA have the same 
postulated mechanism of action, both comprised of a PGA and a NO-donating moiety. 
 
 
 
 
 
 
 
Justification of the Dose Selection for NCX 470 
The IOP-lowering effect of NCX 470 was initially established in normotensive beagle dogs 
and ocular hypertensive non-human primates. In these nonclinical models, topical 
ophthalmic formulations of NCX 470 0.042%, formulated to be equimolar to topical 
ophthalmic formulation of 0.03% bimatoprost, demonstrated 2.0 to 3.5 mmHg superiority in 
IOP-lowering effect compared to 0.03% topical ophthalmic bimatoprost.  
Therefore, clinical dose ranging in the Phase 2 trial was centered on the mid dose of 0.042% 
NCX 470 (equimolar with 0.03% bimatoprost); a low dose of 0.021% NCX 470 (equimolar to 
0.015% bimatoprost); and a high dose of 0.065% NCX 470 (equimolar to 0.05% 
bimatoprost).  
The once-daily (in the evening) dosing regimen for NCX 470 is consistent with that of other 
PGAs. 
The results of the Phase 2 trial “Dolomites”, NCX-470-17001 demonstrated that all tested 
concentrations of NCX 470 (0.021%, 0.042%, and 0.065%) QD met the primary efficacy 
endpoint of non-inferiority to latanoprost 0.005% QD for reduction from baseline in mean 
diurnal IOP at Day 28. In pre-specified secondary efficacy analyses, NCX 470 0.065% was 
superior to latanoprost for mean IOP reduction from baseline at all 3 time points (8AM, 10AM 

CONFIDENTIAL 
NCX-470-02 version 2.0; 08-July-2020 
 
Page 26 of 78 
and 4PM) on Day 28, with the difference reaching up to 1.4 mmHg. Mean IOP reduction from 
baseline at the 3 time points across Days 7, 14 and 28 ranged from 7.6 to 9.8 mmHg for 
NCX 470 0.065% compared with 6.3 to 8.8 mmHg for latanoprost. Additionally, all 
3 concentrations of NCX 470 were well tolerated. The most frequent adverse event was 
conjunctival hyperemia. There were no treatment-related serious adverse events, and no 
evidence of treatment-related systemic side effects. NCX 470 showed linearly increasing 
IOP-lowering efficacy with each incremental concentration of NCX 470 without reaching a 
plateau, with a conjunctival hyperemia dose-response which plateaued at the middle dose 
(0.042%). The separation of the dose-response curves in IOP lowering vs. conjunctival 
hyperemia showed a favorable therapeutic index thereby allowing for a higher concentration 
of NCX 470 (i.e., 0.1%) to be evaluated in this trial alongside the highest dose tested (0.065% 
NCX 470) in the Phase 2 Dolomites trial. An adaptive design will be utilized wherein one of 
the NCX 470 doses will be discontinued during the adaptive evaluation, which will occur after 
at least 30 randomized subjects in each arm complete their Week 2 Visit. 
Justification of the Active Comparator Selection 
Topical PGAs, such as latanoprost, bimatoprost and travoprost, are considered the mainstay 
of treatment for patients with OAG or OHT due to their efficacy and safety in lowering IOP 
(Li, 2016; Daka, 2014). Latanoprost accounted for 71% of all PGA prescriptions in the US in 
2017, and more than one third of all prescribed IOP-lowering medications (IMS Data). As 
latanoprost was the first approved and remains the most widely prescribed PGA, latanoprost 
has a well-established safety and efficacy profile. Latanoprost has been used as comparator 
in the Phase 2 dose-ranging study NCX-470-17001 and NCX 470 0.065% demonstrated its 
superiority to this standard-of-care treatment for mean IOP reduction from baseline at all 
3 time points (8AM, 10AM and 4PM) at the Week 4 Visit, with the difference reaching up to 
1.4 mmHg. Therefore, latanoprost 0.005% is a reasonable choice for an active comparator 
for the NCX 470 Phase 3 program.  
Selection of the Study Population 
A total of approximately 670 male and female adults with OAG or OHT in both eyes will be 
randomized in this clinical study at approximately 50 investigative sites in the US and 
approximately 1 to 3 investigative sites in China. Up to 15 additional sites may be added 
based on enrollment rates.  
 
 
 
1.3 
Potential Risks and Benefits to Human Subjects 
The potential risks to subjects that may occur in this study are likely to be similar to those 
reported during the Phase 2 NCX-470-17001 trial, as well as the clinical development and 
marketing experience of bimatoprost, latanoprost, and latanoprostene bunod ophthalmic 
solutions.

The potential benefit to subjects is lowering of IOP. Elevated IOP represents a major risk 
factor for glaucomatous visual field loss. The higher the level of IOP, the greater the likelihood 
of optic nerve damage and visual field loss. 
The results of the Phase 2 “Dolomites” trial, NCX-470-17001 demonstrated that all tested 
concentrations of NCX 470 (0.021%, 0.042%, and 0.065%) QD met the primary efficacy 
endpoint of non-inferiority to latanoprost 0.005% QD for reduction from baseline in mean 
diurnal IOP at the Week 4 Visit. In pre-specified secondary efficacy analyses, NCX 470 
0.065% was superior to latanoprost for mean IOP reduction from baseline at all 3 time points 
(8AM, 10AM and 4PM) at the Week 4 Visit, with the difference reaching up to 1.4 mmHg. 
Mean IOP reduction from baseline at the 3 time points across the Week 1, 2 and 4 Visits 
ranged from 7.6 to 9.8 mmHg for NCX 470 0.065% compared with 6.3 to 8.8 mmHg for 
latanoprost. Additionally, all 3 concentrations of NCX 470 were well tolerated. The most 
frequent adverse event was conjunctival hyperemia. There were no treatment-related 
serious adverse events, and no evidence of treatment-related systemic side effects. 
NCX 470 showed increased IOP-lowering efficacy with each incremental concentration of 
NCX 470, with a conjunctival hyperemia dose-response which plateaued at the mid-dose 
(0.042%). The separation of the dose-response curves in IOP lowering vs. conjunctival 
hyperemia showed a favorable therapeutic index thereby allowing for a higher concentration 
of NCX 470 (i.e., 0.1%) to be evaluated in this trial alongside the highest dose tested (0.065% 
NCX 470) in the Phase 2 trial.

controlled, Phase 3 clinical trial with adaptive dose selection.  This trial will be conducted in 
approximately 50 sites in the United States and 
 China.
 
 
Subjects will be assessed for initial eligibility at the Screening Visit (Figure 1). Subjects 
currently being treated with an IOP-lowering medication will be required to discontinue their 
IOP-lowering medication during a washout period which will occur between the Screening 
Visit and the Eligibility 1 Visit.
 
 
 
Successful washout and IOP-based eligibility for all subjects will be determined at the 
Eligibility 1 Visit (Day 
 and the Eligibility 2 Visit (Day 
) with diurnal IOP 
measurements at 8AM, 10AM, and 4PM at both visits. The baseline IOP for study eligibility 
will be based on the study eye IOP measurements from the Eligibility 1 and Eligibility 2 Visits. 
Subjects meeting eligibility requirements will be randomized at the end of the Eligibility 2 
Visit.  
 
During the initial adaptive design dose-ranging phase, at least 30 subjects will be 
randomized in each arm in a 1:1:1 ratio to receive NCX 470 ophthalmic solution (0.065% 
or 0.1%), or latanoprost ophthalmic solution, 0.005% QD in the evening, one drop in each 
eye. 
• 
NCX 470 ophthalmic solution, 0.065% (minimum 30 subjects randomized)

All doses will be self-administered or administered by a caregiver topically as eye drops in 
the evening. 
Approximately 640 subjects will be studied for 3 months 
 
 
 
A subject will be considered as having completed the study after completion of the 
Month 3/ Exit Visit (Day 90 [± 3 days]). The overall study duration is estimated to be 
approximately 12 to 15 months from the first subject enrolled until completion of the last 
subject. The maximum duration of subject participation (from the Screening Visit to the 
Month 3/Exit Visit) is approximately 139 days (or approximately 167 days for subjects for 
whom the washout period may be extended during the Adaptive Dose Selection Period).

3.2 
Washout Period for Majority of the Study Subjects 
Subjects currently using IOP-lowering medication(s) must undergo a minimum washout 
period as specified in Table 1 below according to the pharmacological class of their IOP-
lowering therapy.

The minimum washout period will begin at the Screening Visit and will be completed at the 
Eligibility 1 Visit (day 
 (Figure 1).  The time between the Screening Visit and the 
Eligibility 1 Visit should not 
 for any subject.  
After the Eligibility 1 Visit there will be an additional 
 without any IOP-lowering 
treatment before eligibility confirmation and randomization at the Eligibility 2 Visit. The time 
between the Screening Visit and the Eligibility 2 Visit should

All non-ophthalmic medications used in the 3 months prior to the Screening Visit, and all 
ophthalmic medications, including investigational ophthalmic products, used in the 
12 months prior to the Screening Visit must be recorded. Additionally, all medications used 
between the Screening Visit and the Month 3/Exit Visit must be recorded. 
Eligible subjects will discontinue all previous IOP-lowering medication(s), if applicable, on the 
day of the Screening Visit. However, the initiation of treatment with an IOP-lowering 
medication with a shorter washout period than the subject’s IOP-lowering medication at 
screening is permitted between the Screening Visit and Eligibility 1 Visit (see Table 1). 
Additionally, an IOP-lowering medication with a short washout period (e.g., a topical carbonic 
anhydrase inhibitor such as AZOPT) is permitted in non-randomized subjects during the 
Adaptive Dose Selection Period. 
The use of over-the-counter artificial tears or antihistamine eye drops is allowed provided 
they are administered a minimum of 5 minutes before or after the instillation of the study 
medication. 
Diagnostic ophthalmic agents administered throughout the study will not be captured in the 
concomitant medication log.  
5.2 
Prohibited Medication(s)  
All the prohibited drugs mentioned below are also listed in Section 4.4 (“Exclusion Criteria''). 
From the Screening Visit through the Month 3/Exit Visit subjects must not receive:

Storage of the Study Medication  
It is the Principal Investigator’s responsibility to ensure that all study medication is stored in 
a secure area and administered only to randomized subjects and in accordance with 
conditions specified in this protocol.  Only the unmasked site designee authorized by the 
Principal Investigator may have access to the study medication and will be responsible for 
delivering/collecting the study medication to/from the subjects. 
 
 
 
 
 
6.6 
Accountability of Study Medication 
The study medication will be shipped by the study medication supplier to each study site.  
The receipt of study medication by the unmasked site designee should be documented. The 
dispensed and returned study medication will be recorded by the unmasked site designee 
on an inventory log. 
It is the responsibility of the unmasked site designee to maintain detailed study medication 
accountability records.  The importance of returning the kits with all dispensed bottles must 
be emphasized to the subjects.  Study medication deliberately and/or accidentally destroyed 
must be accounted for and the reason must be documented.  Any discrepancy between 
dispensed and returned study medication must be explained and documented by the 
unmasked site designee. 
6.7 
Assigning Subjects to Treatment and Study Masking 
Each site will be assigned a 
 by the Sponsor or its representative. At the 
Screening Visit, the site will assign 
 to 
each subject and record it in the screening log.  The site will then register the subject in the 
EDC system in which they will be issued a

The subjects, investigators, site staff measuring IOP or evaluating safety parameters, the 
Sponsor, the Medical Monitor, and the CRO personnel interacting with the clinical sites (or 
handling study data) will be masked to the treatment assignment. The unmasked site 
designee will only perform handling of study medication, and a limited set of 
procedures
 
 
 
 
   
IRT assignment is based on a randomization schedule created by an unmasked statistician. 
6.8 
Study Medication Dispensing and Collection  
For each subject fulfilling eligibility criteria, the clinical site staff will access the EDC and IRT 
to randomize study subject(s) at the Eligibility 2 Visit (Day 1).  A randomization number will 
be allocated to each subject and study medication kit number will be issued. 
 
 
 
Once all Eligibility 2 Visit study procedures have been completed 
 
 
 
 
 
 
 
 
 
In the event a subject needs a replacement kit, utilize the IRT. If a subject’s study medication 
is lost or destroyed, the subject will be assigned a 
 
from within that 
 will be dispensed.  
Subjects will be instructed to return their study medication 
 only to the 
site’s unmasked site designee at the Week 6 and Month 3/Exit Visits. An inventory will be 
conducted by the unmasked site designee during the conduct of the trial.  
6.9 
Instructions for Use and Administration 
The study medication must be administered one drop in each eye by the subject or caregiver, 
at 
 from the evening of the Eligibility 2 Visit (Day ) to the evening prior 
to the subject’s last study visit. 
No study medication will be administered by the investigational site staff.  
Each subject will be given a copy of the study medication dosing and storage instructions.

6.10 
Emergency Subject Unmasking 
If unmasking of a subject becomes critical to the subject’s safety, the Principal Investigator 
must authorize such decision. If possible, such decision should be first consulted with both 
the study Sponsor and the Medical Monitor. The study treatment assignment of a subject 
should be unmasked via the IRT. In a situation when the IRT system is not accessible, the 
unmasking can be achieved via the scratch-off portion of the study kit label located in the 
source documentation. The Sponsor and the Medical Monitor must be notified within 
24 hours following an emergency unmasking of any subject.  
6.11 
Study Medication Compliance 
It is important to encourage the subject to be compliant with the study treatment. Compliance 
will be captured in a subject diary, and collected at the Week 2, Week 6, and Month 3/Exit 
Visits. The subject will be instructed on diary completion.  
6.12 
Return of Study Medication by the Clinical Sites 
Return of used and unused study medication by the clinical site to the study medication 
supplier should be performed following onsite verification by the CRA. 
6.13 
Other Study Supply 
Sites will also be provided with:

8. SCREEN FAILURES, COMPLETION AND DISCONTINUATION 
8.1 
Subject Screen or Eligibility Failures 
Subjects who are screen or eligibility failures should not be randomized into the study. The 
reason for screen/eligibility failure must be documented in the source document and in the 
eCRF. 
Subjects may be rescreened for participation in the trial following Sponsor’s approval. 
8.2 
Subject Completion 
A subject is considered to have completed the study at the end of the Month 3/Exit Visit. 
8.3 
Subject Early Discontinuation 
A subject may be discontinued from the study prior to the final study visit at the discretion of 
the Investigator, Sponsor, and/or IRB. Subjects may also discontinue their participation in 
the study at any time per their own decision. 
A subject may be discontinued from the study for the following reasons, including but 
not limited to: 
• 
Serious adverse event: If it is determined by the Investigator that only removal 
from the study could reduce subject’s risk or that the occurred SAE prevents the 
subject from further participation in the study treatment or follow-up, the subject 
may be withdrawn.   
• 
Violation of eligibility criteria: In case a subject has been randomized into the study 
despite not meeting study inclusion/exclusion criteria, or non-compliance with 
inclusion or exclusion criteria has occurred during the course of the study, the 
subject may be discontinued.   
• 
Lack of compliance with the study procedures or loss to follow-up.  
• 
.  
A subject must be discontinued from the study for the following reasons, including 
but not limited to: 
• 
 
• 
Withdrawal of consent 
• 
Subject becoming pregnant in the course of the study 
Procedures for Discontinuation 
If a subject is discontinued or withdraws consent during the washout period, no procedures 
other than those which may be related to the follow-up of AEs will be required.  The 
Investigator will document the reason for the subject withdrawal.  
If a subject is discontinued for reasons other than withdrawal of consent during the treatment 
period, the Month 3/Exit Visit assessments should be performed and documented. 
If a subject withdraws their consent during the study treatment period, all efforts should be 
taken to complete Month 3/Exit Visit procedures prior to subject’s exit. 

CONFIDENTIAL

Page 51 of 78 
If a subject is discontinued due to an AE, the status of the AE at the time of discontinuation 
will be recorded in the eCRF.   
 
 
 
Study medication must be returned by the subject to the site unmasked designee, as 
applicable. 
8.4 
Subject Lost to Follow-up 
Subjects who fail to present for a study visit should be contacted in an attempt to have the 
subject comply with the protocol and to return the diary and study medication, if applicable. 
If a subject cannot be contacted with a minimum of three documented telephone calls 
followed by a certified letter and there is no known reason for withdrawal (e.g., withdrawn 
consent), the reason for withdrawal from the study will be recorded as “lost to follow-up”. The 
date of withdrawal will be considered as seven days after the certified letter was mailed. 
8.5 
Study Termination 
Investigators and subjects should understand that the study may be discontinued by the 
Sponsor (Nicox) at any time, without their consent. 
8.6 
Subjects Discontinued Per Protocol Following Adaptive Evaluation 
Subjects, who were randomized to the discontinued dose of NCX 470, must discontinue at 
the next scheduled study visit following the completion of the Adaptive Dose Selection 
Period.

9. PROTOCOL COMPLIANCE 
Subjects who experience major protocol deviations will have all their data excluded from the 
Per Protocol (PP) analysis.  The list of major protocol deviations, as well as minor protocol 
deviations, will be finalized prior to database lock. 
In order to correctly identify and document protocol deviations, protocol deviations will be 
categorized as follows: 
• 
Minor Deviation: Deviation considered to not impact the primary efficacy outcome 
of the study (i.e., does not affect the study results). 
• 
Major Deviation: Deviation considered to impact the primary efficacy outcome of 
the study (i.e., affects the study results). 
All deviations will be recorded by the site and classified by the Sponsor.

10. ADVERSE EVENTS 
10.1 
Adverse Event Definition 
An AE is defined as any untoward medical occurrence in a subject or clinical investigation 
subject administered a pharmaceutical product and which does not necessarily have to have 
a causal relationship with this treatment.  
An AE can therefore be any unfavorable and unintended sign (including an abnormal 
laboratory finding), symptom, or disease temporally associated with the use of a medicinal 
(investigational) product, whether or not considered related to the medicinal (investigational) 
product.  Lack of efficacy will be reported as a treatment failure, not as an AE. 
10.2 
Severity of Adverse Event 
The severity of an AE should be categorized as mild, moderate or severe per Investigator’s 
judgment with the following scale in consideration: 
• 
Mild: Awareness of a sign or symptom that does not interfere with the subject’s usual 
activities or is transient, resolved without treatment and with no sequelae. 
• 
Moderate: interferes with the subject’s usual activities, and or requires symptomatic 
treatment. 
• 
Severe: symptom(s) causing severe discomfort and significant impact of the subject’s 
usual activities and requires treatment. 
10.3 
Causal Relationship with Study Medication 
A determination of the relationship between an AE and the study medication must be made 
by the Investigator for each AE. The following terms to evaluate the causality of the AE with 
the study drug should be used: 
• 
Unrelated: a simultaneous disease, a simultaneous treatment or any other known 
cause is clearly responsible for the safety event and the AE is not related to the study 
medication. 
• 
Unlikely: on the basis of the available knowledge regarding the subject’s history, 
the disease process, the timing of the safety event in relation to the administration 
of the study medication and the mode of action of study medication, a relation 
between the study medication and the safety event is unlikely, but cannot be totally 
excluded.  
• 
Possible: this relation exists when the safety event follows the reasonable 
chronological sequence from the moment of the study medication administration, but 
when the safety event could also have been caused by the clinical condition of the 
subject or by other treatment administered to the subject.  
• 
Probable: this relation exists when the safety event follows a reasonable 
chronological sequence from the moment of the study medication administration, 
corresponds to a known effect of the study medication, is confirmed by the 
observation of an improvement upon discontinuation of the study medication 
administration, and therefore the study medication is the most probable of all the 
causes.  
• 
Definite: this relation exists when the safety event follows a reasonable 
chronological sequence from the moment of the study medication administration, 
corresponds to a known effect of the category of the studied medication, is confirmed 

CONFIDENTIAL 
NCX-470-02 version 2.0; 08-July-2020 
 
Page 54 of 78 
by the observation of an improvement upon discontinuation of the study medication, 
and no other reasonable cause exists.  
Early exit for lack of efficacy/worsening of the disease will not be considered as an adverse 
event but as a treatment failure.  
10.4 
Serious Adverse Events  
SAE is any untoward medical occurrence that at any dose: 
• 
Results in death, or 
• 
Results in-subject hospitalization or prolongation of existing hospitalization, or 
• 
Results in persistent or significant disability/incapacity, or 
• 
Results in a congenital anomaly/birth defect (Section 12.2 - Procedure in Case of 
Pregnancy), or 
• 
Results in life-threatening illness or injury (Note: The term “life-threatening” in the 
definition of “serious” refers to an event in which the subject was at risk of death at 
the time of the event; it does not refer to an event which hypothetically might have 
caused death if it was more severe, or had continued untreated). 
• 
Results in a significant and persistent loss or impairment of vision.  
Additionally, medical events that may not meet these criteria, may be considered an SAE if, 
based on the medical judgment of the Investigator, such medical events may require an 
intervention to prevent any of the outcomes listed above.  
To ensure no confusion or misunderstanding of the difference between the terms "serious" 
and "severe," which are not synonymous, the following note of clarification is provided: the 
term "severe" is often used to describe the intensity of a specific event.  This is not the same 
as "serious," which is based on subject/event outcome or action criteria usually associated 
with events that pose a threat to a subject's life or functioning. 
Elective or planned procedures requiring hospitalization will not be considered SAE’s; 
however, other events may occur during this hospitalization that may be considered serious 
or non-serious adverse events and will need to be captured according to the protocol. 
Subjects must not undergo any elective, or plan any non-urgent procedures for the study 
duration and 30 days following the last treatment administration. 
10.5 
Adverse Event Reporting 
In this study, subjects should be encouraged to report AEs spontaneously or in response to 
general, non-directed questioning (e.g., “How has your health been since the last visit?”).  If 
it is determined that an AE has occurred, the Investigator should obtain all the information 
required to complete the AE Form(s).  
Additionally, subjects will be instructed to contact the Investigator, and/or study coordinator 
if any significant AEs occur between study visits.  
All AEs that occur from the signing of the ICF on the day of the Screening Visit through the 
Month 3/Exit Visit must be recorded on the appropriate AE form.  All AEs must be reported 
whether or not considered causally related to study medication.  For every AE, the Principal 
Investigator will provide an assessment of the severity and causal relationship to study 
medication, document all actions taken with regard to study medication, and any other 
treatment measures for the AE.   

CONFIDENTIAL 
NCX-470-02 version 2.0; 08-July-2020 
 
Page 55 of 78 
10.6 
Serious Adverse Event Reporting 
Any SAE occurring from the signing of the ICF on the day of the Screening Visit, and up to 
30 days following the most recent study drug administration (for a subject who exited the 
study early or after normal study completion) must immediately be reported to the company 
representing Nicox, and recorded on the appropriate forms.  All subjects with an SAE must 
be followed up and the outcomes reported. Subjects must be followed until complete healing 
or stabilization or blood tests are back to normal or up to 30 days after the end of the study 
treatment, whichever occurs first.  The Investigator must supply the company representing 
Nicox with any additional requested information (e.g., autopsy reports and final medical 
reports). 
In the event of an SAE, the Investigator must: 
1) Notify Sponsor’s Primary Contact for Study Related Matters and SAEs immediately 
(see contact information on Page 3 and Section 12.1), at the latest within 24 hours 
of becoming aware of the initial SAE.  Complete an SAE Form (see instructions for 
completion of SAE Form in Appendix 3) and send it to the Primary Contact for Study 
Related Matters and SAEs. Retain all submission confirmations with the items 
submitted.  
2) Obtain and maintain in subject’s files pertinent medical records, information, and 
medical judgments from colleagues who assisted in the treatment and follow-up of 
the subject.  
3) Complete and submit further follow-up reports for data collected until the SAE has 
resolved or a decision for no further follow up has been taken.  
4) Promptly inform the local IRB and/or other applicable regulatory body as required by 
local regulations.

11. STATISTICAL CONSIDERATIONS AND METHODS OF ANALYSIS 
A final analysis plan containing detailed statistical methods, including accounting for 
multiplicity, will be generated and finalized prior to database lock following the completion of 
the 3-month safety and efficacy evaluation period. There will be a single final statistical 
analysis plan for this multi-regional trial. 
Additionally, an interim analysis plan containing detailed statistical methods, including 
accounting for multiplicity, will be generated and finalized prior to the interim analysis 
supporting the adaptive evaluation of at least 30 subjects in each treatment arm through 
Week 2.  
11.1 
Determination of Sample Size and Power Calculations 
The primary objective of this study is to demonstrate that mean IOP reduction from time-
matched baseline (baseline minus follow-up) for NCX 470 (0.065% or 0.1%) is non-inferior 
to latanoprost ophthalmic solution, 0.005%.   
  
  
 
• 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
  
11.2 
Analysis Population 
For the 3-month treatment evaluation period, three different populations will be used in the 
analysis: an intent-to-treat (ITT) population, a Per Protocol (PP) population, and a safety 
population. 
The ITT population will include all randomized subjects. Demographics, baseline 
characteristics, and efficacy variables will be analyzed using the ITT population. These 
analyses will be performed on an as-randomized basis. 
The PP population will include all randomized subjects who received study medication, who 
had at least one follow-up visit and who had no major protocol deviations (see Section 9) 

CONFIDENTIAL 
NCX-470-02 version 2.0; 08-July-2020 
 
Page 57 of 78 
during the 3-month treatment period. The final PP population will be determined and 
approved by Nicox prior to database lock.  Demographics, baseline characteristics, and 
efficacy variables will be analyzed using the PP population. These analyses will be performed 
on an as-treated basis.   
The safety population will include all randomized subjects who received at least one dose of 
the study medication during the 3-month treatment period and will be used for the safety 
analyses. All safety variables will be analyzed on an as-treated basis using the safety 
population. 
11.3 
Data Display 
Data will be analyzed separately using the following treatment groups wherever appropriate: 
• 
NCX 470 ophthalmic solution, 0.065% 
• 
NCX 470 ophthalmic solution, 0.1% 
• 
Latanoprost ophthalmic solution, 0.005% 
11.4 
Collection and Derivation of Primary Efficacy Assessments 
At the Screening Visit, IOP will be measured at 8AM 
min., 10AM 
 min., or 4PM ± 
min. From the Eligibility 1 Visit to the Month 3 Visit, IOP will be measured at 8AM 
 min., 
10AM 
 min. and 4PM 
 min. IOP measurements will be conducted in both eyes. 
Handling of missing values: 
The primary efficacy analyses will be based on the ITT population with multiple imputation 
(MI) methods. To check for robustness of outcomes, missing data will be handled using 
 
 detailed in the formal statistical analysis 
plan. 
11.5 
Hypothesis and Methods of Analysis 
11.5.1 Primary Efficacy Analysis  
The primary efficacy assessment is the non-inferiority analysis of the difference in the 
treatment effect between NCX 470 and latanoprost 0.005% for mean IOP reduction from 
time-matched baseline at the 8AM and 4PM time-points at the Week 2, Week 6 and Month 3 
Visits in the study eye. 
Efficacy will be assessed by the primary variable: 
Mean reduction from baseline (average of Eligibility 1 and Eligibility 2 Visits) in time-matched 
IOP at the 8AM and 4PM time points at the Week 2, Week 6 and Month 3 Visits. 
The primary analysis of the primary outcome will employ a linear model with mean IOP at 
the given visit (Week 2, Week 6, and Month 3) and time point (8AM and 4PM) as the 
response, baseline IOP as a covariate, and treatment as a main effect, using the ITT 
population with multiple imputation techniques used to impute missing data.  
The primary analysis for superiority will be completed similarly.

11.5.3 Safety Analysis 
Safety analyses are based on the safety dataset.  The safety population will include all 
subjects who receive at least one dose of study medication. 
Subject disposition, demographics, and baseline characteristics will be summarized and 
presented in data listings. 
A treatment-emergent AE (TEAE) is defined as an AE that occurred on or after the treatment 
was initiated.  Ocular TEAEs by treatment group: NCX 470 0.065, NCX 470 0.1% and 
latanoprost 0.005%, will be summarized, by relationship to study drug, and by severity.  Non-
ocular TEAEs will be summarized by treatment group as follows: non-ocular TEAEs, by 
relationship to study, and by severity.  Serious AEs (SAEs), AEs resulting in study drug 
discontinuation, and deaths will be presented in data listings. 
Other ocular safety data will be summarized for treated study eyes and fellow eyes 
separately, with the exception of ocular adverse events, which will be summarized at the 
subject level accounting for all treated eyes.

12. EMERGENCY PROCEDURES 
12.1 
Emergency Contact Procedure 
In case of any Safety Event including an SAE, the first person to contact is: 
 
 
 
 
The secondary contact is the study Medical Monitor: 
 
 
 
 
The Principal Investigator is responsible for ensuring that procedures and expertise are 
available to cope with medical emergencies during the study.  Each subject will receive the 
Investigator’s emergency contact information (to call if needed).   
12.2 
Procedure in Case of Pregnancy 
If a pregnancy occurs during the study, pregnancy itself is not regarded as an AE unless 
there is a suspicion that the study medication may have interfered with the effectiveness of 
a contraceptive medication. 
If a female subject becomes pregnant during the study, the subject will be withdrawn from 
the study immediately.  However, any pregnancies must be followed up, and their outcomes 
must be reported to Nicox or to the company representing Nicox (i.e., mother and fetus(es) 
must be followed up at least until the birth of the infant and one month after the birth of the 
infant). Follow-up will include course, duration, outcome of the pregnancy and the health of 
the infant, as applicable. 
If the outcome of pregnancy is:  
• 
Elective abortion without complications: it must be documented and reported to Nicox 
or to the company representing Nicox, but it should not be handled as an AE.   
• 
Any spontaneous miscarriage or abortion for medical reasons or congenital anomaly 
or birth defect: it must be documented and handled as a SAE and full details will be 
requested.   
Any complications during pregnancy must be recorded as AEs and may constitute SAEs if 
they fulfill any of the specified criteria for a SAE.

13. STUDY MANAGEMENT 
13.1 
Monitoring 
Site monitoring is conducted to assess that subject protection, study procedures, study drug 
administration, and data collection processes meet protocol, ICH, GCP, and regulatory 
guidelines/requirements.   
Before the study starts, the company representing Nicox will visit/call the investigational sites 
to: 
• 
Determine the adequacy of the facilities, 
• 
Discuss with the Investigator(s), and other personnel involved in the study, about their 
responsibilities with regard to protocol adherence, and also about Sponsor’s 
responsibilities. 
During the study, a masked Clinical Research Associate (CRA) will monitor the study on a 
periodic basis by having regular contacts with the investigational sites, including on-site 
and/or remote visits, to: 
• 
Provide information and support to the Investigator(s), 
• 
Confirm that facilities and investigational site staff remain acceptable, 
• 
Ensure that the investigational site study team is adhering to the protocol, including 
verifying the accuracy of data recorded in the eCRF. 
Additionally, an unmasked CRA will monitor the site on a regular basis to ensure that all 
study medication is stored in a secure area and in accordance with the storage conditions 
indicated on the label of the outer kits. The unmasked CRA will also provide oversight of 
temperature excursions. Finally, the unmasked CRA will monitor the site to ensure that study 
medication is only dispensed to randomized subjects, and that all dispensed and returned 
study medication is recorded by the unmasked site designee on an inventory log. 
Any detected non-compliance with the approved study protocol, GCP, or any applicable 
regulatory requirements will be fully documented by the monitor. During the monitoring visits, 
the Investigator and clinical study staff should be available for questions, verification of data 
from the source documentation, and possible correction to the eCRF. 
Following each monitoring visit, the Investigator will be sent a follow up letter detailing any 
actions required by either the investigational site staff or the monitor.  Any actions must, 
wherever possible, be addressed immediately, or by the next scheduled monitoring visit. 
The monitor and the CRO’s clinical operations team will be reachable between visits if the 
Investigator, or other study staff at the site, needs information and advice. 
13.2 
Source Documents 
Each participating site will maintain appropriate medical and research records for this trial, in 
compliance with ICH E6(R2) GCP Section 4.9, and regulatory and institutional requirements 
for the protection of subject confidentiality. 
Source data are all information, original records of clinical findings, observations, or other 
activities in a clinical trial necessary for the reconstruction and evaluation of the trial. 

CONFIDENTIAL 
NCX-470-02 version 2.0; 08-July-2020 
 
Page 63 of 78 
Source documents may include, but are not limited to, a subject’s medical records, hospital 
charts if any, clinic charts if any, the Investigator’s subject study files, pharmacy dispensing 
records, recorded data from automated instruments, as well as the results of diagnostic tests. 
13.3 
Source Data Verification 
To ensure that data in the eCRF is accurate and complete and in accordance with subject 
source documents and other source data, source data verification (SDV) will be performed 
by the monitor on eCRF’s and SAE and pregnancy related documents as detailed in the 
Monitoring Plan (MP).  The SDV consists of a comparison of the source documentation and 
other relevant records to the eCRFs.  This will require direct access to all original records for 
each subject. 
It will be verified that documentation of the informed consent is on file for all subjects 
screened whether or not they were randomized into the study. 
13.4 
Completion of Electronic Case Report Forms  
eCRFs must be completed for each subject enrolled in the trial, including screening 
failures.  eCRFs should be completed as soon as possible after the subject visit.  All 
eCRFs must be checked for consistency, accuracy, and completeness by the responsible 
Investigator and personally electronically signed and dated by them.   
13.5 
Data Management 
The study Data Management Plan (DMP) will describe the methods used to collect, check 
and process clinical data, as well as the process for database locks.  The DMP will be 
developed by the company representing Nicox and approved by Nicox.  It will also list the 
roles and responsibilities of the various functions and personnel involved in the data 
management process. 
 
 
13.6 
Audits and Inspections 
Authorized representatives of Nicox or the company representing Nicox, a regulatory 
authority, or an IRB/IEC may visit the site to perform audits or inspections, including source 
data verification.  The purpose of such 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 approved protocol, GCP, ICH guidelines, and any applicable regulatory 
requirements.  The Investigator must contact Nicox or the company representing Nicox 
immediately if contacted by a regulatory agency about an inspection at their site. 
The presence of the CRA at the site is mandatory in case of an inspection or audit (at least 
for the SDV audit and the debriefing with the Principal Investigator).  Nevertheless, when 
justified, the CRA may be represented by another CRO representative involved in the study 
(e.g., lead CRA).  
13.7 
Access to Source Data 
Nicox, authorized representatives of the company representing Nicox, or regulatory authority 
representatives will be allowed to have full and direct access to the various records relating 

CONFIDENTIAL 
NCX-470-02 version 2.0; 08-July-2020 
 
Page 64 of 78 
to the trial (e.g., Subject’s data records, diagnostic tests) to verify adherence to the protocol 
and the completeness, consistency, and accuracy of the data being reported. 
13.8 
Training of Staff 
The Principal Investigator will maintain records of all individuals at their site involved in the 
study (medical, nursing, and other staff).  The Principal Investigator will ensure that 
appropriate training relevant to the study is given to all of the study staff, and that any new 
information of relevance to the performance of this study is forwarded to the staff involved.  
The Principal Investigator must inform the monitor, in a timely manner, of any change in the 
study site staff. 
13.9 
Changes to the Protocol 
Neither the Investigator nor the site staff may implement any changes to the protocol without 
approval by Nicox and prior review and documented approval/favorable opinion from the IRB 
of a protocol amendment, except where necessary to eliminate immediate hazards to study 
subjects, or when the changes involve only logistical or administrative aspects of the study 
(e.g., change in monitors, change of telephone numbers).  If a protocol amendment requires 
a change to a particular site's Informed Consent Form, then Nicox or the company 
representing Nicox and the site's IRB must be notified.  Approvals of the revised Informed 
Consent Form by Nicox or the company representing Nicox, and the IRB are required before 
the revised form is used. 
Nicox or the company representing Nicox will distribute amendments and new versions of 
the protocol to each Principal Investigator(s) and site study staff for review and any applicable 
training.

Good Clinical Practice (ICH GCP E6 (R2) - March 2018), and the applicable regulatory 
requirements.  
14.2 
Ethical Principles 
The study has to be conducted in accordance with the principles of the Declaration of Helsinki 
(1964), as amended or clarified by the General Assembly of the World Medical Association 
(World Medical Association Declaration of Helsinki, last amended October 2013). 
14.3 
Health Authorities and Institutional Review Board (IRB)  
This study is to be conducted in accordance with IRB regulations (U.S. 21 CFR Part 56). 
The study protocol and subject informed consent form must be submitted to the appropriate 
properly constituted IRB.  The approval from the IRB must refer to the exact protocol title and 
number, and identify all documents reviewed and their corresponding versions.  A list of the 
IRB review board members as well as a statement of compliance with GCP and applicable 
laws and regulations should be also provided.  Copies of all IRB correspondence with the 
Investigator should be given to the company representing Nicox. 
The company representing Nicox is to be notified immediately if the responsible IRB has 
been disqualified or if proceedings leading to disqualification have begun. 
The Principal Investigator is also responsible for providing the IRB with safety reports of any 
unexpected SAEs from any clinical study conducted with the study medication, as dictated 
by the IRB requirements.  These safety reports will be provided to the Principal Investigator 
by the company representing Nicox. 
The Principal Investigator is responsible for informing the IRB of any amendment to the 
protocol.  In addition, the IRB must approve all materials used to recruit subjects for the 
study.  Either the Principal Investigator, or the company representing Nicox, must submit 
progress reports to the IRB according to the IRB requirements and local regulations and 
guidelines.  The Principal Investigator must also provide the IRB with any reports of Serious 
Adverse Events from the study site, as dictated by the IRB requirements. 
14.4 
Subject Information and Consent 
It is the responsibility of the Investigator to obtain written and signed informed consent prior 
to enrollment into the study (i.e., at the Screening Visit) and before any procedure related to 
the trial is performed.   
The methods of obtaining and documenting informed consent and the contents of the ICF 
will comply with ICH GCP guidelines, the requirements of 21 CFR Part 50 “Protection of 
Human Subjects”, the Health Insurance Portability and Accountability Act (HIPAA) 
regulations for subjects in the U.S. and appropriate local guidelines, requirements, and 
regulations for the subjects in China, and all other applicable regulatory requirements. 
The Investigator or their designee must fully explain and adequately inform the subject of the 
purpose of the study prior to entering a subject into the clinical trial or performing any trial-
specific procedures.  

CONFIDENTIAL 
NCX-470-02 version 2.0; 08-July-2020 
 
Page 66 of 78 
Once the subject fully agrees to participate in this study, written ICF must be documented by 
the subject’s personally dated signature and the personally dated signature of the informing 
Investigator/designated person conducting the informed consent discussion.  The subject will 
receive one copy and the original ICF will be filed in the subject study file on site. 
The dates when the written informed consent was obtained for the subject and when the 
subject withdraws or exits the study, must be documented in the subject source documents 
so that it is known if the subject is currently participating in a clinical study. 
In signing the ICF, a subject accepts direct access to their data by Nicox, the company 
representing Nicox, monitor, auditor, and Health Authority representatives. 
14.5 
Confidentiality Regarding Trial Subjects Data 
In order to maintain subjects’ privacy, all study materials will identify subjects in a fully 
anonymized manner. The Investigator will grant the company or its designated 
representatives, or regulatory authorities the right to access subject’s original medical 
records for verification of the data gathered in the study. Subject’s confidentiality will be 
maintained and will not be made publicly available unless mandated by applicable laws and 
regulations. 
14.6 
Archiving at the End of the Study 
After the close-out visit at each site, the study is considered completed.  A copy of the final 
completed CRFs will be stored in the Investigator's archives for up 2 years following the final 
approval of the last marketing authorization, together with all the other site study-specific 
documents (including Investigator’s site file).  Neither of these is ever transferred to the 
Sponsor. 
All study-related materials must be stored in a secure manner and must remain available 
upon request from Nicox or any Health Authority.

APPENDIX 2: METHODS OF CLINICAL EVALUATION 
 
For all assessments, sites should use the same instrument(s) and the same examiner whenever 
possible throughout the study. All ophthalmic assessments will be performed bilaterally.  The 
right eye will be assessed first, then the left eye.  
1. URINE PREGNANCY TEST 
Urine pregnancy test is to be conducted on site by study staff per the instructions on the 
pregnancy kit at Screening, Eligibility 1, Week 6 and Month 3/Exit Visits.  
 
2. MANIFEST REFRACTION AND BEST CORRECTED VISUAL ACUITY (BCVA) 
The manifest refraction and visual acuity (VA) measurements should be obtained by a 
physician, optometrist, or trained technician, and every effort should be made to have the same 
assessor complete the assessment for a given subject using the same equipment and method 
every time. 
2.1 
Manifest Refraction  
Manifest refraction will be performed using the site’s standard procedures.  Refraction will be 
assessed at the Screening Visit and must be repeated
 
. 
The correction obtained and recorded at Screening will be used (i.e., placed in trial frames, 
use of phoropter/optometer or equivalent) for each measurement of best corrected visual 
acuity (BCVA) at follow-up visits.

4. PUPIL SIZE 
Measurement of pupil diameter will be performed at the Screening, Eligibility 1, Eligibility 2, 
Week 2, Week 6 and Month 3/Exit Visits using a pupillary gauge. 
Measurement of pupil size should occur after assessment of BCVA and using the same 
illumination for each subject visit at each visit throughout the course of this study.  
Measurement of pupil diameter should occur to the nearest 0.5 mm using a pupillary gauge 
while the subject fixates on a distant, non-accommodative target. To avoid stimulating the 
accommodative response and consequential constriction, the pupillary gauge should be held 
away from the visual axis of the subject.
