reliever effect as prescribed by the Investigator 
10. Mean central corneal thickness greater than 620 μm in either eye at screening 
11. Any abnormality preventing reliable applanation tonometry of either eye 
(eg, keratoconus, etc.) 
 
Systemic:

13. Clinically significant systemic disease (eg, uncontrolled diabetes, myasthenia gravis, 
hepatic, renal, endocrine or cardiovascular disorders) which might interfere with the 
study 
14. Participation in any investigational study within 60 days prior to screening  
15. Systemic medication that could have a substantial effect on IOP within 30 days prior 
to screening, or anticipated during the study, including any corticosteroid-containing

Subject Enrollment 
Enrollment numbers are higher in this study (230 subjects per arm) than statistically required 
for demonstrating efficacy at 90% power, accounting for an estimated 15% discontinuation 
rate over the course of the first 3 months of the study.  
5. STUDY TREATMENTS 
5.1 
Description of Treatments 
5.1.1 
Investigational Product 
• PG324 Ophthalmic Solution is a sterile, isotonic, buffered aqueous solution 
containing AR-13324 (0.02%), latanoprost (0.005%), boric acid, mannitol, water for 
injection, and preserved with benzalkonium chloride (0.02%).  The product 
formulation is adjusted to approximately pH 5.  
5.1.2 
Comparator Products 
• Latanoprost Ophthalmic Solution, 0.005% is a sterile, isotonic, buffered aqueous 
solution of latanoprost with a pH of approximately 6.7 and an osmolality of 
approximately 267 mOsmol/kg. Each mL of Latanoprost Ophthalmic Solution, 
0.005% contains 50 micrograms of latanoprost.  Benzalkonium chloride, 0.02% is 
added as a preservative. The inactive ingredients are sodium chloride, sodium 
dihydrogen phosphate monohydrate, disodium hydrogen phosphate anhydrous, and 
water for injection. 
• AR-13324 Ophthalmic Solution is a sterile, isotonic, buffered aqueous solution 
containing AR-13324 (0.02%), boric acid, mannitol, water for injection, and 
preserved with benzalkonium chloride (0.015%).  The product formulation is adjusted 
to approximately pH 5. 
5.2 
Treatments Administered  
There will be 3 treatments in this study:  
• PG324 (AR-13324, 0.02% and latanoprost, 0.005%) Ophthalmic Solution  
• AR-13324 Ophthalmic Solution, 0.02% 
• Latanoprost Ophthalmic Solution, 0.005%  
Subjects will be assigned according to a computer-generated randomization list in a 1:1:1 
ratio to PG324 Ophthalmic Solution, AR-13324 Ophthalmic Solution, 0.02%, or Latanoprost 
Ophthalmic Solution, 0.005% (stratified by investigative site and by maximum baseline IOP 
[< 25 mmHg vs ≥ 25 mmHg]).  Subjects will instill 1 drop of study drug into each eye, one 
time per day in the evening, at approximately 24 hour intervals; all treatments will be OU.  
Doses will be self-administered by the study subjects.  For subjects deemed unable to 

PG324 Ophthalmic Solution 
Clinical Study Protocol: PG324-CS301, Amendment 4 
Aerie Pharmaceuticals, Inc. 
 
Confidential 
Page 45 of 123 
 
self-administer the doses, a caregiver will be asked to administer the medication. All subjects 
will administer study treatment for approximately 365 days. 
5.3 
Selection and Timing of Dose for Each Subject 
The dose of PG324 selected for this study is based upon the positive outcomes seen for 
PG324 in the PG324-CS201 clinical study.  Each investigational product is being dosed 
QD OU (in the evening between 20:00 and 22:00 hours) in this study to allow for estimated 
peak and trough levels of both AR-13324 and latanoprost to be present in ocular tissue at the 
observation times selected in the clinic for the following morning and the subsequent 
afternoon.  The treatment period is selected on the basis of nonclinical safety studies and 
regulatory requirements for pivotal studies of ophthalmic glaucoma medications.  
5.4 
Method of Assigning Subjects to Treatment Groups 
A randomization code for allocating the treatments will be prepared by an independent 
biostatistician who is not involved in the day-to-day conduct of the study.  Subjects will be 
randomized using an IWRS in a 1:1:1 ratio to receive PG324 Ophthalmic Solution, 
AR-13324 Ophthalmic Solution, 0.02%, or Latanoprost Ophthalmic Solution, 0.005%.

An independent person at the site not responsible for performing any of the study procedures 
is assigned to dispense, collect, and store investigational product while maintaining the 
masking of the study. 
Study related site personnel will be cautioned that any used or unused subject kits are not to 
be opened at the clinical site by the site staff involved in efficacy or safety measurements.   
Treatment assignments will be masked to the Investigator, the clinical study team 
(Sponsor, personnel involved in day to day study management, Data Managers, and 
Statisticians), and the subjects prior to all subjects completing 3 months of treatment.  
Treatment assignment(s) will be unmasked and made available to the Investigator and the 
Sponsor’s Medical Monitor during this period only in case of medical emergency or 
occurrence of adverse events that in the opinion of the investigator warrant unmasking.  
In the absence of medical need, the randomization code/treatment assignment(s) will not be 
available to the above study personnel until after the study is completed and the database is 
locked.  
If the Investigator feels it is necessary to unmask a subject’s treatment assignment after an 
emergency situation, the Investigator should promptly contact the Sponsor’s Medical 
Monitor or designee.  A decision will be made as to whether or not the treatment for the 
subject should be unmasked, preferably after consultation with the Sponsor’s Medical 
Monitor or designee.  The treatment assignment will be revealed on a subject-by-subject 
basis, thus leaving the masking on remaining subjects intact.

In an emergency situation in which treatment of an adverse event requires immediate 
unmasking, and the Investigator is unable to promptly contact the Sponsor’s Medical 
Monitor, the Investigator may unmask the treatment.  The masked portion of the kit label 
may be revealed for the treatment assignment.  In the case of such unmasking in an 
emergency situation, the Investigator should contact the Sponsor immediately thereafter and 
document the unmasking in writing, recording the date, time, and reason for unmasking the 
study drug treatment in the source documentation.  Individual unmasking by the Investigator 
will normally result in withdrawal of the subject from the study and should only be 
performed for the specific subject requiring unmasking in their treatment group.   
5.6 
Concomitant Therapy 
Intermittent use of over-the-counter (OTC) artificial tear lubricant products is acceptable, 
with a minimum of 10 minutes between use of OTC products and study medication.  
However, concurrent therapy with any form of ocular hypotensive medications 
(prescription or over-the-counter) is not allowed during the study.  Subjects who are not 
taking any concomitant disallowed ocular medication or who do not require washout of 
ocular hypotensive medication can return as soon as clinical chemistry and hematology 
results are received for Qualification Visit #1 (see Section 7.1.2 of this protocol for more 
details). 
Disallowed concomitant ocular medications for enrolled subjects include: 
• Miotics  
• Epinephrine-related compounds  
• Carbonic anhydrase inhibitors (ocular or systemic)  
• α-adrenoceptor agonists  
• β- adrenoceptor antagonists 
• Muscarinic agonists (eg, pilocarpine)  
• Prostaglandin analogues other than that contained in the provided investigational 
product 
Systemic therapy with agents that could have an effect on IOP is to be consistent in dose, 
regimen and agent within the 30 days prior to screening and throughout the study, except for 
corticosteroid-containing drugs.  For example, a subject can be treated with a systemic β-
adrenoceptor antagonist as long as the particular agent and its dose and regimen had been 
consistent for the 30 days prior to screening, and there is no reason to believe that alteration 
would be necessary at some point later during the study.  Subjects should be cautioned to 
avoid use of alcohol or the use of drugs such as marijuana during the study visit days.

Page 47 of 123 
Any corticosteroid-containing systemic drug is disallowed during the study regardless of 
route of administration.    
Contact lens wear during the study is acceptable.  However, subjects must remove their 
contact lenses at least 30 minutes before instillation of study medication, and not place them 
in their eye(s) until 30 minutes after instillation.   
Use of all medications should be documented on the appropriate CRF.  Investigators are 
encouraged to contact the Sponsor for any questions regarding allowed medications.  
Judgment of continued study participation by the subject, and inclusion of this subject’s 
subsequent visits in the safety and efficacy analysis will be made by the Sponsor.   
All medications which the subject has taken within 30 days prior to screening and during the 
study will be recorded in the CRF.  The name of the drug, dose, route of administration, 
duration of treatment and indication will be recorded for each medication.  For combination 
products (eg, Contac®), the brand name is required.  For non-combination products, the 
generic name is desired.  The use of routine ophthalmic diagnostic pharmaceutical agents 
(eg, fluorescein and local anesthetic) will be allowed, and individual documentation not 
required.  Any change in dosing parameters should also be recorded in the CRF.   
5.7 
Restrictions 
5.7.1 
Prior Therapy 
Individuals currently using ocular hypotensive medications must undergo a minimum 
washout period as specified in Table 1.  If washout is to be extended beyond 6 weeks 
(42 days) for logistical or other reasons, the Sponsor should be contacted.  If subjects need to 
washout of a hypotensive medication, they are not allowed to use a washout medication of 
shorter required washout time (including Azopt) than for the original hypotensive 
medication.

Ophthalmic Solution, 0.005% will be removed and replaced with an investigational label 
which will be similar in appearance for all treatment groups.   
Upon dispensing of a clinical trial material packer or kit to a subject, a portion of the kit label 
will be affixed to the designated study drug kit label log which will be part of the study files 
at the individual study site for this study. 
5.10 
Storage and Accountability  
The investigational products should be stored refrigerated (2°C to 8°C/36°F to 46°F) until 
provided to the subject.  The subject should be instructed that, once an investigational 
product bottle is opened, the product may be kept refrigerated or at room temperature 
(up to 25°C/77°F) while continuing to store the bottle in the carton.  Do not freeze the 
product and protect from light.  Prior to dispensing to the subject, all investigational material 
must be stored in a secure location at the recommended long-term storage condition 
(2°C to 8°C) with strictly limited access documented by signature of authorized persons who 
may dispense investigational product. Temporary temperature excursions up to 30°C are 
permissible. 
5.11 
Investigational Product Accountability at Study Site   
5.11.1 
Receipt and Disposition of Study Medication 
Investigational product will be shipped to the Investigator’s site from a central depot.  
A study staff member at the Investigator’s site who is not involved in conducting any 
efficacy or safety procedures will verify study medication shipment records by comparing the 
shipping documentation accompanying the study medication to the study medication actually 
received at the Investigator’s site.  If a discrepancy is noted, the appropriate individual at the 
Sponsor or designee must be notified immediately.  The responsible person for dispensing 
study medication at the Investigator’s institution is the only site staff member that can 
distribute investigational product and also has sole responsibility to account for all returned 
used, partially used and unused bottles and kits of investigational products.  The 
investigational product(s) must not be used outside this protocol.  A Drug Accountability Log 
will be kept at the clinical site.  
5.11.2 
Return of Study Medication 
When the study is completed or is terminated by the Sponsor, all study material including 
used and unused study medication kits will be returned to the Sponsor or their designee.  
All study medication accounting procedures must be completed before the study is 
considered to be concluded.  The responsible person at the Investigator’s institution has the 
sole responsibility to account for all used, partially used and unused bottles of investigational 
products.  This site staff member at the Investigator’s institution will complete a study drug 
returns form or equivalent that will be signed by the Investigator or designee prior to 
returning the used and unused study medication kits and bottles to the Sponsor or their 
designee.

Study staff responsible for dispensing investigational product will be listed on the Delegation 
of Responsibilities log.  When a subject meets all criteria for selection and has completed all 
screening assessments, the subject will be assigned to a treatment according to the interactive 
web-based response system (IWRS).  The responsible study staff will account for all used 
and unused investigation product packers and their kit contents by maintaining an 
investigational product accountability log.   
6.4 
Appropriateness of Measurements 
The ophthalmic and systemic measures used in this study are consistent with standard of 
care.  In particular, intraocular pressure (IOP) as measured by Goldmann applanation 
tonometry, the primary efficacy assessment in this study, is accepted worldwide as a standard 
for testing of pharmacologically active agents intended to reduce IOP. 
6.5 
Efficacy Assessments 
6.5.1 
Specification of the Efficacy Parameters  
The primary efficacy outcome will be the comparison of PG324 Ophthalmic Solution relative 
to each of its active components, AR-13324, 0.02% and latanoprost, 0.005%, for the mean 
IOP within a treatment group at 08:00, 10:00, and 16:00 hrs at the Week 2, Week 6, and 
Month 3 study visits.  A description of the method for measuring IOP to be used in this study 
is contained in Appendix 2.  Study visits at Month 6, Month 9, and Month 12 will focus 
primarily on safety and will include measurement of IOP at 08:00, 10:00 and 16:00 hrs. 
Secondary efficacy outcomes will include a summary of the following comparisons of 
PG324 Ophthalmic Solution relative to each of its active components (AR-13324, 0.02% and 
latanoprost, 0.005%) for: 
• Mean IOP within a treatment group at each post-treatment time point  
• Mean diurnal IOP within a treatment group at each post-treatment visit 
• Mean change from diurnally adjusted baseline IOP at each post-treatment time point  
• Mean change from baseline in diurnal IOP at each post-treatment visit  
• Mean percent change from diurnally adjusted baseline IOP at each post-treatment 
time point 
• Mean percent change from baseline in diurnal IOP at each post-treatment visit  
• Percentages of subjects achieving pre-specified mean, mean change, and percent 
mean change diurnal IOP levels  
Other secondary efficacy analyses will be carried out as described in the study Statistical 
Analysis Plan.

All treatment-emergent adverse events occurring during the study, regardless of the 
assumption of causal relationship, must be documented on the respective CRF.  
Adverse events should be documented from the time the subject receives the first dose of 
Investigational Product until the subject’s participation in the study has been completed.  
If a subject has an ongoing adverse event at the time of study completion, the ongoing 
adverse event must be followed-up and provided appropriate medical care until the event has 
resolved or stabilized.   
Documentation of adverse events/adverse reactions includes start date and stop date, severity, 
action(s) taken, seriousness and outcome.   
6.9.2 
Adverse Event Definitions 
The following definitions of terms apply to this section: 
• Adverse event: any untoward medical occurrence associated with the use of a drug in 
humans, whether or not considered drug related.   
• Life-threatening adverse event or life-threatening suspected adverse reaction: an 
adverse event or suspected adverse reaction is considered “life-threatening” if, in the 
view of either the Investigator or Sponsor, its occurrence places the subject or subject 
at immediate risk of death.  It does not include an adverse event or suspected adverse 
reaction that, had it occurred in a more severe form, might have caused death.   
• Serious adverse event (SAE) or serious suspected adverse reaction (SSAR):  an 
adverse event or suspected adverse reaction is considered ‘‘serious’’ if, in the view of 
either the Investigator or Sponsor, it results in any of the following outcomes: Death, 
a life-threatening or sight-threatening adverse event, in subject hospitalization or 
prolongation of existing hospitalization, a persistent or significant incapacity or 
substantial disruption of the ability to conduct normal life functions, or a congenital 
anomaly/birth defect.  Important medical events that may not result in death, be 
life-threatening, or require hospitalization may be considered serious when, based 
upon appropriate medical judgment, they may jeopardize the subject and may require 
medical or surgical intervention to prevent one of the outcomes listed in this 
definition.  Examples of such medical events include allergic bronchospasm requiring 
intensive treatment in an emergency room or at home, blood dyscrasias or 
convulsions that do not result in subject hospitalization, or the development of drug 
dependency or drug abuse. 
• Suspected adverse reaction: any adverse event for which there is a reasonable 
possibility that the drug caused the adverse event.  For the purposes of IND safety 
reporting, ‘‘reasonable possibility’’ means there is evidence to suggest a causal 
relationship between the drug and the adverse event.  Suspected adverse reaction 
implies a lesser degree of certainty about causality than adverse reaction, which 
means any adverse event caused by a drug.

Clinical Study Protocol: PG324-CS301, Amendment 4 
Aerie Pharmaceuticals, Inc.

Page 55 of 123 
 
• Unexpected adverse event or unexpected suspected adverse reaction:  an adverse 
event or suspected adverse reaction is considered ‘‘unexpected’’ if it is not listed in 
the Investigator’s Brochure or is not listed at the specificity or severity that has been 
observed; or, if an Investigator’s Brochure is not required or available, is not 
consistent with the risk information described in the general investigational plan or 
elsewhere in the current application, as amended.  For example, under this definition, 
hepatic necrosis would be unexpected (by virtue of greater severity) if the 
Investigator’s Brochure referred only to elevated hepatic enzymes or hepatitis.  
Similarly, cerebral thromboembolism and cerebral vasculitis would be unexpected 
(by virtue of greater specificity) if the Investigator’s Brochure listed only cerebral 
vascular accidents.  “Unexpected,” as used in this definition, also refers to adverse 
events or suspected adverse reactions that are mentioned in the Investigator’s 
Brochure as occurring with a class of drugs or as anticipated from the 
pharmacological properties of the drug, but are not specifically mentioned as 
occurring with the particular drug under investigation. 
Note: Any medical condition present prior to administration of the masked study medication 
which remains unchanged or improved should not be recorded as an adverse event at 
subsequent visits. 
Note: If an event occurs during the washout period, prior to subject enrollment and the 
commencement of study medication, it should be recorded as part of the Medical History and 
not as an adverse event.  As noted in Section 7.1.2, any change in their Visit 1 (screening) 
health status should be recorded on the Medical History page of the CRF (eg, the subject has 
been diagnosed with cancer). 
Note: In the present study, Investigators are asked to use the verbatim term “conjunctival 
hyperemia” on the study AE form to describe observations of conjunctival redness if the 
ocular redness observation is increased from Visit 1 (Screening) observations.  Investigators 
are also asked to note all observations of conjunctival hyperemia on the biomicroscopy CRF 
as well as on the study AE form. 
6.9.3 
Timing for Reporting of Adverse Events 
The AEs occurring during the study must be documented, regardless of the assumption of a 
causal relationship.  AEs should be documented from the time the subject receives the first 
dose of investigational product until subject participation in the study has been completed.  
If a subject has one or more ongoing AEs at the time of study completion, the subject must 
be followed and provided appropriate medical care until the sign(s) and/or symptoms(s) of 
the AE have remitted or stabilized in the opinion of the Investigator. 
When recording an AE, the following information should be provided on the study AE CRF: 
1. Action Taken with Study Drug:  
• None 

PG324 Ophthalmic Solution 
Clinical Study Protocol: PG324-CS301, Amendment 4 
Aerie Pharmaceuticals, Inc.

Page 56 of 123 
 
• Investigational Product Discontinued 
• Investigational Product Interrupted 
2. Other Action Taken:  
• None 
• Non-Drug Therapy 
• New OTC or Rx Drug Added 
• Hospitalized less than 24 hours 
• Hospitalized greater than or equal to 24 hours 
3. Outcome of an adverse event is to be coded as: 
• Fatal 
• Not Recovered/Not Resolved 
• Recovered/Resolved 
• Recovered/Resolved with sequelae 
• Recovering/Resolving 
• Unknown/Lost to follow-up 
6.9.4 
Severity 
Severity of an adverse event is defined as a qualitative assessment of the level of discomfort 
or the degree of intensity of an adverse event as determined by the Investigator or reported to 
him/her by the subject.  The assessment of severity is made irrespective of study medication 
relationship or seriousness of the event and should be evaluated according to the following 
scale: 
• 1 = Mild: present and noticeable, but not distressing, and no disruption of normal 
daily activities 
• 2 = Moderate:  bothersome, discomfort sufficient to possibly reduce or affect normal 
daily activity 
• 3 = Severe: incapacitating, with inability to work or perform normal daily activity 

PG324 Ophthalmic Solution 
Clinical Study Protocol: PG324-CS301, Amendment 4 
Aerie Pharmaceuticals, Inc. 
Confidential 
Page 57 of 123 
A change in severity for a reported AE will require a stop date for the previous severity and a 
new start and stop date for the new severity.  For example, a change in severity may go from 
mild to severe, or from severe to moderate.  In either case, the start and stop dates should be 
recorded.   
Please note: a severe AE is not the same as a serious AE.  Seriousness of an AE (NOT 
severity) serves as a guide for defining regulatory reporting obligations (see Section 6.9.9 for 
further information on serious AEs [SAEs]). 
6.9.5 
Relationship 
The study medication relationship for each adverse event/adverse reaction should be 
determined by the Investigator using these explanations: 
•
Not Related: The event is clearly related to other factors such as subject’s clinical
condition, therapeutic interventions, concomitant disease or therapy administered to
the subject and does not follow a known response pattern to the product.
•
Unlikely Related: The event is most probably caused by other etiologies such as
participant’s underlying condition, therapeutic intervention, or concomitant therapy;
or the delay between administration and the onset of the AE is incompatible with a
causal relationship. Therefore, there is not a reasonable possibility that the AE was
caused by the study medication.
•
Possibly Related:  The event follows a reasonable, temporal sequence from the time
of study medication administration and/or follows a known response pattern to the
study medication, but could have been produced by other factors such as the subject’s
clinical state, therapeutic interventions or concomitant therapy administered to the
subject.
•
Related:  The event follows a reasonable, temporal sequence from the time of study
medication administration and/or follows a known response pattern to the study
medication and cannot be reasonably explained by other factors such as subject’s
clinical state, therapeutic interventions or concomitant therapy administered to the
subject, and either occurs immediately following study medication administration, or
improves on stopping the study medication, or reappears on repeat exposure, or there
is a positive reaction at the application site.
6.9.6 
Expectedness 
For AR-13324, the most frequently reported AE in 3 Phase 2 studies (AR-13324-CS201, 
AR-13324-CS202, and PG324-CS201) has been conjunctival hyperemia.  Other AEs seen in 
greater frequency with AR-13324 than in active control treatment arms in these studies 
include instillation site erythema or pain, conjunctival hemorrhage, blurred vision, eye 
irritation, increased lacrimation, and foreign body sensation. 

PG324 Ophthalmic Solution

Confidential 
Page 58 of 123 
 
The most common AEs seen with Latanoprost Ophthalmic Solution, 0.005% in clinical trials 
as reported in the latanoprost prescribing information (Appendix 3) include conjunctival 
hyperemia, eyelash changes, increased iris pigmentation, eyelid skin darkening, macular 
edema (including cystoid macular edema), and intraocular inflammation (iritis/uveitis). 
An AE or suspected adverse reaction is considered “unexpected” if it is not listed in the 
Investigator’s Brochure or is not listed at the specificity or severity that has been observed.  
“Unexpected,” as used in this definition, also refers to adverse events or suspected adverse 
reactions that are mentioned in the Investigator’s Brochure as occurring with this class of 
drugs or as anticipated from the pharmacological properties of AR-13324 or latanoprost, and 
are not specifically mentioned as occurring with the investigational product.  The AEs that 
are both unexpected and serious should be reported in an expedited fashion to the Sponsor 
(see Section 6.9.10 for further details). 
6.9.7 
Clinical Significance 
Determination of whether a finding is clinically significant will be made by the Principal 
Investigator or the Sub-Investigator and will be documented on the CRF. 
6.9.8 
Clinical Laboratory Adverse Events 
Clinical laboratory values (other than pregnancy tests results) that are noted as abnormal and 
clinically significant at study exit and that are changes from Visit 1 (screening) values will be 
documented as AEs. 
6.9.9 
Serious Adverse Events (SAEs) or Serious Suspected Adverse Reactions  
6.9.9.1 
Reporting Serious Adverse Events 
An investigator must immediately report any SAE or SSAR (see Section 6.9.2 for 
definitions) to the Sponsor or Rho Product Safety, the Sponsor CRO representative, whether 
or not the SAE or SSAR is considered drug-related, including those listed in the protocol or 
Investigator’s Brochure.  The investigator report must include an assessment of whether there 
is a reasonable possibility that the drug caused the event.  The Investigator must report any 
SAE or SSAR that occurs during the study for a subject or any SAE or SSAR that occurs 
within 4 weeks (ie, 30 days) after the last administration of IP. Study endpoints that are 
serious adverse events (eg, all-cause mortality) must be reported in accordance with the 
protocol unless there is evidence suggesting a causal relationship between the drug and the 
event (eg, death from anaphylaxis).  In that case, the Investigator must immediately report 
the event to the Sponsor.  The investigator must record non-serious adverse events and report 
them to the Sponsor according to the timetable for reporting specified in the protocol.  In 
case of incomplete information, the Investigator must provide follow-up information as soon 
as possible, again using the SAE report form.   
In addition, in the case of immediately life-threatening AEs or AEs with fatal outcome, or 
adverse events that are serious, unexpected (ie, not in the Investigator’s Brochure) and

6.9.11 
Follow-up of Subjects after Adverse Events 
If an adverse event/adverse reaction occurs, the Investigator will institute support and/or 
treatment as deemed appropriate.  If a non-serious adverse event/adverse reaction is 
unresolved at the time of the last visit, efforts will be made to follow up until the adverse 
event/adverse reaction is resolved or stabilized, the subject is lost to follow-up, or there is 
other resolution to the event.  
6.10 
Comfort Test 
Individuals will be asked “Did you experience any discomfort when placing the drops in your 
eyes?”  This will refer to the study medication use the previous evening.  The response will 
be scored as None, Mild, Moderate or Severe. 
6.11 
Best Corrected Visual Acuity (BCVA) 
Best corrected visual acuity (BCVA) will be taken at visits as a measure of ocular function 
and will be measured at screening and frequently throughout the study. Visual acuity will be 
measured using ETDRS charts or their equivalents.  Accepted charts are those designed 
according to the principles described by Ferris and coworkers (Ferris 1982) and supported by 
the guidelines from the Eye Care Technology Forum (Ferris 1996). 
See Appendix 2 for details of the procedures to be followed when determining BCVA.   
6.12 
Pupil Size 
Pupil size will be measured prior to dilation with a ruler to the nearest 0.5 mm in ambient 
room light. 
6.13 
Biomicroscopy 
Biomicroscopic examination of the eyelids, conjunctiva, cornea, anterior chamber, lens, iris, 
and pupil of both lenses will be carried out at every study visit for both eyes of subjects.  
Normal or abnormal status of these ocular tissues will be graded as described in Appendix 2.  
6.14 
Gonioscopy/Pachymetry 
Gonioscopy will be used to confirm the iridocorneal angle is open and to what extent. 
Eligible subjects must have an angle grading of 3 or 4 (Shaffer grading scale: Kolker 1976) 
for participation in the study.  Pachymetry will be used to measure the thickness of the 
central cornea.  Both of these assessments will be done in order to determine the eligibility of 
a subject to be enrolled in this study.  Further information on these procedures is found in 
Appendix 2.

Actions after Discontinuation 
All subjects who discontinue Investigational Product due to a report of an AE must be 
followed-up and provided appropriate medical care until their signs and symptoms have 
remitted or stabilized or until clinically significant abnormal laboratory findings have 
returned to acceptable or pre-study limits. 
For the subject who chooses to withdraw consent or who is discontinued for non-compliance, 
every possible effort should be made by the Investigator to assure there is an exit visit that 
includes all examinations listed for Visit 9.0 (Day 365) and dilated ophthalmoscopy.   
6.17.4 
Discontinuation of the Entire Study  
The entire study may be discontinued at a given site (by the Investigator or the Sponsor) or

7. STUDY ACTIVITIES 
The schedule of study visits and procedures is shown in Appendix 1. 
7.1 
Study Visits  
7.1.1 
Visit 1 (Screening Visit) 
This visit may occur at any time of the day.  Individuals who are potential subjects will arrive 
at the Investigator’s office at any time point during the day.   
A member of the Investigator’s staff will interview the individual as to their qualifications for 
participation in the study.  Individuals will be asked to review the informed consent, discuss 
issues as needed, and to sign the form.  Significant medical and ophthalmic history including 
systemic and ocular medication use will be taken, and demographic measures recorded 
(see Section 6.2).  An examination will be conducted, including measurement of heart rate 
and blood pressure, a urine pregnancy test (for females of childbearing potential), collection 
of a blood sample for clinical laboratory assessments, and an ophthalmic examination to 
include symptoms, best corrected visual acuity (BCVA), intraocular pressure (before pupil 
dilation), biomicroscopy, gonioscopy, central corneal thickness by ultrasound pachymetry, 
visual field testing, and dilated ophthalmoscopy.  Gonioscopy and visual fields may be taken 
up to three months (ie, within 90 days) prior to randomization.  If assessment of visual fields 
requires dilation due to subject small pupils, visual field testing should not take place within 
48 hours of Visit 2 (Qualification Visit #1).  
Pachymetry must be taken at screening Visit 1 or within one week of Visit 1.  The results of 
blood work should be reviewed after this study visit in order to determine eligibility of the 
subject prior to undertaking the examination at Visit 2 (Qualification Visit #1).  For subjects 
who are unable or unwilling to have blood drawn for clinical labs at Visit 1 (screening), the 
blood sample may be drawn at Visit 2 (Qualification Visit #1) so long as the results of the 
clinical labs are available for that subject prior to Visit 3 (Qualification Visit #2). 
All females of childbearing potential must have a negative urine pregnancy test result at the 
screening examination and must not intend to become pregnant during the study. 
The Investigator will evaluate the results of these examinations for possible enrollment of the 
individual into the study.  All individuals who are qualified for enrollment at this study visit 
should undergo a washout period (if needed) as noted in Section 5.7.1 and will be asked to 
return for Visit 2 (Qualification Visit #1).  
7.1.1.1 
Evaluation of eye-drop instillation performance 
Subjects (or a legally authorized representative for subjects deemed unable to 
self-administer) will be provided a bottle of commercially available, multi-dose,

non-medicated artificial tears in a room with access to water and soap.  Medication instiller 
will be asked to instill a drop of the artificial tear in each eye under the observation of a 
member of the investigator’s staff.  The staff will observe the subject or representative to 
assure that they instill one drop of the artificial tear into each eye, without touching the tip of 
the bottle to their eye or face (Stone 2009).  The staff member may work with the individual 
to improve their delivery technique to meet this standard.  If the instiller (or representative) 
cannot demonstrate proper delivery of the eye drop, or if staff member feels that the 
individual will be unable to do so consistently, then the subject will be excluded from further 
study participation.   
7.1.1.2 
Washout 
As noted in Section 5.7.1., a washout period is required for individuals currently using ocular 
hypotensive medications.  The Investigator is encouraged to have interim visits during the 
washout period for intraocular pressure measurement for individuals to whom the washout 
period may be a risk for further glaucomatous progression.  
7.1.2 
Visit 2 (Qualifying Visit #1, for 08:00 hours IOP measurement) 
After the washout, if required, individuals will return to the Investigator’s office in the early 
morning.  For individuals not requiring washout of ocular hypotensive medication, this visit 
should take place at least one day and no later than approximately 28 days subsequent to the 
screening visit.  The subject will be questioned regarding any changes in their health or 
concomitant medication use.  Any change in the individual’s Visit 1 health status or use of 
concomitant medications should be recorded on the Medical History page of the CRF 
(eg, the subject has been diagnosed with cancer).  Inclusion/exclusion criteria will be 
reviewed again for the qualified individual, and the subject’s heart rate and blood pressure 
will be measured.  Results of the clinical laboratory tests from Visit 1 need to be available, 
and reviewed by the Investigator. For subjects who were unable or unwilling to have blood 
drawn for clinical labs at Visit 1, the blood sample may be drawn at Visit 2 
(Qualification Visit #1) so long as the results of the clinical labs are available for that subject 
prior to Visit 3 (Qualification Visit #2). 
The following procedures then will be performed: 
• Symptomatology: Individuals will be asked “How are you feeling?”  
• Best corrected visual acuity 
• A non-dilated eye examination will be performed, including IOP and biomicroscopy 
o IOP must be measured within 30 minutes of the nominal time (ie, 07:30 to 
08:30 hours) 
o IOP measurements:  Unmedicated (post-washout) IOP > 20 mmHg and 
< 36 mmHg in both eyes at this qualification visit at 08:00 hour is required. This 
is the first of four qualifying IOPs for randomization.  Individuals who do

NOT meet this requirement may return for up to 2 additional (unscheduled) 
qualification visits within 1 week of failing this qualification visit.  Individuals 
returning at an unscheduled visit within 1 week are required to only re-measure 
IOP in both eyes.  Individuals who screen fail due to IOP being ≥ 36 mmHg in 
either eye at this study visit or at an unscheduled visit within 1 week of the 
original visit MAY NOT return for additional qualification visits and are to be 
exited from the study. 
Qualified individuals who have met all criteria at this study visit will be scheduled to return 
2-7 days later for the second qualification visit.   
7.1.3 
Visit 3.0 (Qualifying Visit #2 [Day 1] for IOP measurement at 08:00 hours) 
Within 2 to 7 days after Visit 2, individuals will return to the Investigator’s office for the next 
08:00 hour IOP measurement.  The results of the clinical laboratory tests from Visit 1 or 
Visit 2 need to be available, and reviewed by the Investigator.  In order for the individual to 
be enrolled at a subsequent visit, the tests CANNOT be indicative of any clinically 
significant disease in the opinion of the Investigator.  The subject will be questioned 
regarding any changes in their health or concomitant medication use.  Any change in the 
individual’s health relative to their Visit 1 (screening) or Visit 2 health status and 
concomitant medication use should be recorded on the Medical History page of the CRF 
(eg, the subject has been diagnosed with cancer).  Inclusion/exclusion criteria will be 
reviewed again for the qualified individual.   
The following procedures will be performed: 
• Symptomatology: Individuals will be asked “How are you feeling?” 
• Heart rate and blood pressure 
• Best corrected visual acuity 
• A non-dilated eye examination will be performed, including pupil size, IOP and 
biomicroscopy   
o IOP must be measured within 30 minutes of the nominal time (ie, 07:30 to 
08:30 hours) 
o IOP measurements:  Unmedicated (post-washout) IOP > 20 mmHg and 
< 36 mmHg in both eyes at this study visit at 08:00 hour is required.  This is the 
second of four qualifying IOPs for randomization.   
Qualified individuals will continue with the measurements of IOP at 10:00 hours and 
16:00 hours on the day of this study visit.  Individuals who do NOT meet the above IOP 
requirement may return for up to 2 additional (unscheduled) qualification visits within 
1 week of failing this qualification visit.  Individuals returning at an unscheduled visit within 
1 week are required to only re-measure IOP in both eyes.  Upon return for an unscheduled

qualification visit, such individuals’ IOP measurements would need to qualify at each of 
08:00, 10:00 and 16:00 hours.  Individuals who screen fail due to IOP being ≥ 36 mmHg in 
either eye (exclusion criterion) at any of these time points at this study visit or at an 
unscheduled visit within 1 week of the original visit MAY NOT return for additional 
qualification visits and are to be exited from the study. 
Individuals are allowed to leave the Investigator’s office on the day of this study visit 
between assessments, and eat and drink with no restrictions.  However, individuals are not to 
consume alcohol or engage in strenuous exercise.  
7.1.4 
Visit 3.1 (Day 1, for IOP measurement at 10:00 hours) 
Inclusion/exclusion criteria will be reviewed again for the qualified individual.  
Qualified individuals will be examined.  Each examination will include: 
• Symptomatology: Individuals will be asked “How are you feeling?” 
• A non-dilated eye examination will be performed, including IOP and biomicroscopy  
o IOP must be measured within 30 minutes of the nominal time (ie, 09:30 to 
10:30 hours) 
 
At this and any other in-office visit, any subject complaining of visual function issues 
will have visual function assessed as judged appropriate by the Investigator.   
For further participation in the study, unmedicated IOP at this time (10:00 hours, Day 1) 
must be > 17 mmHg and < 36  mmHg in both eyes.  This is the third of four qualifying 
IOPs for randomization.   
Qualified individuals will continue with the qualification visit.  Individuals who do NOT 
meet this requirement may return for up to 2 additional unscheduled qualification visits 
within 1 week of failing this qualification visit.  Individuals returning at an unscheduled visit 
within 1 week are required to only re-measure IOP in both eyes.  Upon return, such 
individuals would need to qualify at 08:00, 10:00 and 16:00 hours.  Individuals who screen 
fail due to IOP being ≥ 36 mmHg in either eye (exclusion criterion) at any of these time 
points at this study visit or at an unscheduled visit within 1 week of the original visit MAY 
NOT return for additional qualification visits and are to be exited from the study. 
Individuals are allowed to leave the Investigator’s office on the day of this study visit 
between assessments, and eat and drink without restrictions.  However, individuals are not to 
consume alcohol or engage in strenuous exercise. 
7.1.5 
Visit 3.2 (Day 1, for IOP measurement at 16:00 hours) 
Inclusion/exclusion criteria will be reviewed again for the qualified individual.   
Qualified individuals will be examined.  Each examination will include:

• Symptomatology: Individuals will be asked “How are you feeling?” 
• A non-dilated eye examination will be performed, including IOP and biomicroscopy 
o IOP must be measured within 30 minutes of the nominal time (ie, 15:30 to 
16:30 hours) 
For further participation in the study, unmedicated IOP for a subject must be > 17 mmHg and 
< 36 mmHg in both eyes at this time (16:00 hours, Day 1).  This is the fourth of four 
qualifying IOPs for randomization.   
Individuals who do NOT meet this requirement may return for up to 2 additional 
unscheduled qualification visits within 1 week of failing the first qualification visit.  
Individuals returning at an unscheduled visit within 1 week are required to only re-measure 
IOP in both eyes.  Upon return, such individuals would need to qualify at 08:00, 10:00 and 
16:00 hours.  Individuals who screen fail due to IOP being ≥ 36 mmHg in either eye 
(exclusion criterion) at any of these time points at this study visit or at an unscheduled visit 
within 1 week of the original visit MAY NOT return for additional qualification visits and 
are to be exited from the study. 
As noted in Section 4.2, subjects must qualify in both eyes based upon IOP and ocular 
history.  For a subject who qualifies, the study eye will be the eye with the higher IOP at 
08:00 hours on Visit 3.  If both eyes have the same IOP at 08:00 hours on Visit 3, then the 
right eye will be the study eye.  In each subject, BOTH eyes will be treated.   
At this point, eligible subjects will be enrolled and assigned to an investigational product 
through an IWRS system according to a computer-generated randomization list.  The first kit 
removed from an investigational product packer assigned through the IWRS system to the 
eligible subject will be dispensed unopened to the subject, along with written storage 
instructions.   
Subjects will be:  
• Instructed to self-administer their masked medication at home between 20:00-22:00

Sample Size Considerations 
Efficacy: 
One-hundred ninety six (196) subjects per arm completing 3 months of treatment yields at 
least 90% power to conclude statistical superiority of PG324 to latanoprost and >99% power 
to conclude statistical superiority of PG324 to AR-13324 at all nine time points assuming a 
two-sided alpha = 0.05, a true mean difference of 1.5 mmHg (to latanoprost) and 2.0 mmHg 
(to AR-13324), a common standard deviation of 3.5 mmHg at each time point, and 
independence among time points.  Power increases as the correlation among time points 
increases.  Therefore, 196 subjects per arm yield at least 90% power to conclude superiority 
to both controls over all nine time points.   
9.3 
Analysis Populations  
Randomized Population: The randomized population will include all subjects who were 
randomized to treatment.  Baseline variables and demographic characteristics will be 
summarized for this population. 
Intent-to-Treat Population (ITT): The ITT population will include all randomized subjects 
who have received at least one dose of study medication.  This population will be the primary 
population for efficacy analyses and will be used to summarize all efficacy variables and will 
summarize subjects as randomized. 
Per-protocol population (PP): The PP population is a subset of the ITT population, which 
will include those subjects (and their visits) who do not have major protocol violations likely 
to seriously affect the primary outcome of the study as judged by a masked evaluation prior 
to the unmasking of the study treatment.  This population will be the secondary population 
for efficacy analyses and will be used to summarize a subset of efficacy variables.  If the PP 
and ITT populations are exactly the same, then additional efficacy analyses on the PP 
population will not be performed.  The PP population will summarize subjects as treated.

Safety Population: The safety population will include all randomized subjects who have 
received at least one dose of study medication.  This population will be used to summarize 
safety variables and will summarize subjects as treated.   
9.4 
Statistical Methods to be Employed 
9.4.1 
General Considerations 
All continuous study assessments will be summarized by treatment and time point 
(as applicable) using descriptive statistics (n, mean, median, standard deviation, minimum, 
and maximum).  All categorical study assessments will be summarized by treatment and time 
point (as applicable) using frequency counts and percentages.   
Hypothesis testing, unless otherwise indicated, will be performed at a 2-sided 
0.05 significance level.  When applicable, two-sided 95% confidence intervals will be 
reported.  All p-values will be displayed to four decimal places, with p-values less than 
0.0001 presented as '<0.0001' and p-values greater than 0.9999 presented as ‘>0.9999’.  
Differences between PG324 and each comparator (latanoprost and AR-13324) will be 
calculated as PG324 – comparator.   
All study data will be listed by treatment, subject and time point (as applicable).  
For diurnally-adjusted IOP, baseline will refer to the time-relevant measure at Visit 3.0 
through 3.2 (eg, IOP at 08:00 hours at Visit 3.0 will be the baseline for 08:00 hours at 
Visit 4.0, Visit 5.0, and Visit 6.0; IOP at 10:00 hours at Visit 3.1 will be the baseline for 
10:00 hours at Visit 4.1, Visit 5.1, and Visit 6.1; etc.).  For all other variables, baseline is 
defined as the last measurement prior to the first dose of study medication.  
The unit of analysis for efficacy will be the study eye.  For a subject who qualifies, the study 
eye will be the eye with the higher IOP at 08:00 hours on Visit 3.  If both eyes have the same 
IOP at 08:00 hours on Visit 3, then the right eye will be the study eye. 
Data collected during the observation extension visits may be summarized separately from 
the data collected during the main portion of the study. 
Statistical methods will be more fully described in separate document(s) (ie, the Statistical 
Analysis Plan).   
9.4.2 
Interim Analyses 
When all subjects have completed three months of treatment, the Sponsor will unmask the 
study to analyze the 3 month efficacy and safety data.  This is the time for primary efficacy 
analysis of the study.  Efforts will be made to keep the Investigators, site staff, and subjects 
masked as to individual subject assignments, as the subjects continue to be evaluated for 
safety for the following 9 months. The Sponsor will conduct an additional data base lock and 
unmask the study when all subjects have completed their 12 month visit. This is the time for 
primary analysis of the 12 month safety data. Interim analyses will be conducted so as to

Page 83 of 123 
•
Percentages of subjects achieving pre-specified mean, mean change, and percent
mean change diurnal IOP levels
Other secondary efficacy analyses will be conducted as described in the study Statistical 
Analysis Plan.  Note that each subject will have one eye designated as the study eye.  
Only the study eyes will be evaluated for the primary efficacy measure or for selected 
secondary efficacy measures; however, both eyes will be treated.   Qualifying fellow eyes 
will be evaluated separately for the primary analysis of the primary efficacy measure.    
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 (08:00, 10:00, and 
16:00 hours) as the response, baseline IOP as a covariate, and treatment as a main effect 
factor, using the intent to treat population with multiple imputation techniques 
(eg, Monte Carlo Markov Chain) used to impute missing data.  Each time point within each 
visit will be modeled separately.  The least squares mean differences (test – control) between 
PG324 Ophthalmic Solution and each of Latanoprost Ophthalmic Solution, 0.005% and 
AR-13324 Ophthalmic Solution, 0.02% will be presented as well as 2-sided p-values and 
95% confidence intervals. For a given comparator (latanoprost and AR-13324), if the p-value 
is P < 0.05 and the point estimate < 0 for all time points at the Week 2, Week 6, and Month 3 
Visits, then the corresponding null hypothesis will be rejected in favor of the alternative 
hypothesis and PG324 will be considered to be superior to the comparator.  Results will be 
presented in both tabular and graphical form. 
Analyses will be performed primarily on the ITT population using multiple imputation 
techniques to impute missing data and secondarily using: observed data only, last observation 
carried forward (LOCF) where LOCF will be performed using time-relevant measures; and 
baseline observation carried forward (BOCF) using time-relevant measures to determine the 
robustness of results.  Additionally, the above analyses will be repeated on the PP population 
to determine robustness of results.  Additional imputation techniques may be designated in 
the formal statistical analysis plan.  Sample SAS code to demonstrate the methodology that 
will be used for data imputation can be found in Appendix 7. 
Secondary analyses of the primary endpoint will be completed using individual two-sample 
t-tests and 95% t-distribution confidence intervals for each comparison (PG324 vs 
latanoprost and AR-13324) at each time point (08:00, 10:00, and 16:00 at the Week 2, 
Week 6, and Month 3 Visits) using the ITT population. Similar analyses will be completed 
on the secondary endpoints: mean IOP measure at each time point and visit and mean diurnal 
IOP and change from baseline diurnal IOP measures.  Models adjusting for baseline will only 
be performed on the mean IOP response variable as inference is identical between this 
response and the change from baseline IOP response variable in such a model. 
Additionally, for the mean IOP values at each time point, mixed model repeated measures 
will be run with baseline as the covariate; treatment, visit, time point, treatment by visit, 
treatment by time point, visit by time point, and treatment by visit by time point as the fixed 
effect factors; and subject as the random effect, repeated measure.  An unstructured 
covariance structure will be used to model the within subject, between visit and time point

for relation to Investigational Product and by severity.  Fisher’s exact test will be used to test 
the difference in proportions of subjects with each AE between treatment groups 
(SOC and PT).   
9.5 
Procedure for Accounting for Missing, Unused, or Spurious Data   
Analyses will be performed primarily on observed data only (without imputation) and 
secondarily using: last observation carried forward (LOCF) where LOCF will be performed 
using time-relevant measures (ie, from the same time point of the most recent visit with a 
non-missing value); BOCF using time-relevant measures; and using multiple imputation 
methods to determine the robustness of results.  Any missing, unused, or spurious data will 
be noted in the final statistical report. 
9.6 
Procedure for Reporting Deviations from the Statistical Plan   
Any deviations from the statistical plan will be described and a justification given in the final 
statistical report. 
9.7 
Data Listings   
Data listings will be prepared for all data on the database.

agencies) may be granted direct access to the study subject’s original medical and study 
records for verification of the data or clinical study procedures. Access to this information 
will be permitted to representatives of the aforementioned organizations to the extent 
permitted by law.  
A report of this study’s results may be published or sent to the appropriate health authorities 
in any country in which the study drug may ultimately be marketed, but subject identities will 
not be disclosed in these documents. 
10.8 
Study Monitoring 
Clinical research associates hired or contracted by the Sponsor will be responsible for 
monitoring the study sites and study activities.  They will contact and visit the Investigator 
regularly.  The actual frequency of monitoring visits depends on subject enrollment and on 
study site performance.  Among others, the following items will be reviewed: 
•
Study progress
•
Compliance with the protocol
•
Completion of CRFs
•
Dispensing, storage, and accountability of IP, including intentional or inadvertent
unmasking of IP
•
Source data verification
•
AE and SAE reporting
•
Essential documents contained within the regulatory binder
For source data verification (ie, comparison of CRF entries with subject records), data will be 
100% source verified and will include as a minimum:  
•
Subject identification
•
Informed consent (procedure, signature, and date)
•
Selection criteria
•
Primary efficacy and safety parameters (ie, AEs)
Member(s) of the Sponsor or their designee will meet with the Investigator prior to the 
initiation of the study in order to assess the adequacy of the Investigator's subject population, 
facilities, and equipment, and to familiarize the Investigator with the protocol.

Page 90 of 123 
A member of the Sponsor or their designee in the role of Study Monitor will subsequently 
meet with the Investigator after several of the subjects have initiated the study in order to 
ensure that the subjects are being properly selected, that adequate supplies for the study have 
been provided and that the assignment of medication is properly recorded. In addition, the 
Study Monitor will verify that the Investigator follows the approved protocol and all 
approved amendments, if any, by reviewing the Investigator’s regulatory documents, source 
documents, Informed Consent Forms, and Case Report Forms of study subjects. 
The Study Monitor will meet with the Investigator when all subjects have completed the 
Final Visit of the study, in order to collect the Case Report Forms, unused study medications, 
and unused supplies and materials. 
Interim monitoring visits and telephone consultations will be done by the Study Monitor as 
necessary, to ensure the proper progression and documentation of the study. 
10.9 
Case Report Forms and Study Records 
The initial point of entry of study data should be the subject source documentation.  The 
location and nature of the source documentation for all data collected in the study will be 
identified in the study files at the investigator’s site.  In cases where no source documents 
will be used (ie, data will be recorded directly onto the case report form (CRF) without first 
being recorded on another document, such as a flowsheet, laboratory report, or other typical 
form of data reporting for later transcription to the CRF), the original data will be included in 
the CRF.  
Source document information should be legible. Recorded data should only be corrected by 
drawing a single line through the incorrect entry and writing the revision next to the 
corrected data. The person who has made the correction should place his or her initials as 
well as the date of the correction next to the correction. Data may not be obliterated by 
erasure, redaction, or with correction fluid. 
Study data will be transcribed and recorded via an electronic data capture (EDC) system as 
electronic CRFs (eCRFs). Security and authorization procedures consistent with the EDC 
system must be used. At each subject visit, the appropriate eCRFs must be completed.  
Whenever an eCRF is used, be sure to provide all information requested including subject 
identification number and initials, name or number of Investigator, date(s), etc.  
All applicable questions should be answered and all data requested should be provided.  
Those areas that require a response but are not filled in correctly are considered incomplete 
or erroneous entries, and will have to be corrected.   
Each authorized study staff member will receive a unique access account in order to use the 
EDC system. Access accounts will not be shared among study staff. Authorized users will 
make entries and/or changes to eCRFs via a secure internet access. Each completed set of 
eCRFs will be reviewed by the Investigator who will then electronically sign and date the 
eCRF confirming that data for the subjects are complete and accurate. 

PG324 Ophthalmic Solution 
Clinical Study Protocol: PG324-CS301, Amendment 4 
Aerie Pharmaceuticals, Inc.

The study records must include a copy of each Investigator's CV and medical license, 
completed, FDA Form 1572 or statement of Investigator, each eCRF, subject charts/source 
documents, Investigator’s Brochure, protocol, protocol amendments, correspondence with 
the Sponsor and the IRB/IEC, IP storage, receipts, returns and dispensing records, Delegation 
of Responsibilities Log, site training records, records of site monitoring, any unmasking 
documentation, AE and SAE reporting, IRB/IEC approvals, advertisements, written 
information provided to subjects, and subject completed ICFs. If the Investigator moves, 
withdraws from an investigation, or retires, the responsibility for maintaining the records 
may be transferred to another person (eg, Sponsor, other Investigator) who will accept the 
responsibility. Notice of this transfer, including written acceptance, must be made to and 
agreed upon by the Sponsor. 
10.10 Protocol Deviations 
A protocol deviation occurs when there is non-adherence to study procedures or schedules 
which does not involve inclusion/exclusion criteria or the primary efficacy endpoint and 
which does not place the subject at any added risk or affect the data quality or study outcome. 
Examples of deviations include common out of window visits or timed procedures, a missed 
procedure, etc. Sites will record protocol deviations in the study records. To the extent 
possible, sites will make their best efforts to quickly remedy deviations. 
The site will contact the Sponsor for clarification of inclusion/exclusion criteria as needed 
prior to enrollment of a study subject. The Sponsor will document clarification requests and 
responses. If a potential subject does not meet all inclusion and exclusion criteria during 
screening, that subject may not be enrolled in the study. 
The site will notify the Sponsor or their representative and IRB/IEC within 10 days of 
becoming aware of any significant protocol deviation. Typically, significant protocol 
deviation include significant deviations from the inclusion and exclusion criteria that may 
impact interpretation or the quality of efficacy information or the safety of a subject, 
concomitant medication restrictions, or any other protocol requirement that results in a 
significant added risk to the subject or has an impact on the quality of the data collected or 
the outcome of the study. 
The Sponsor will review, designate, and/or approve all protocol deviations prior to database 
lock. 
10.11 Access to Source Documentation 
Monitors, auditors, and other authorized representatives of the Sponsor, the governing 
IRB(s)/IEC(s), the FDA, the DHHS, other domestic government agencies, and other foreign 
regulatory agencies will be granted direct access to the study subject’s original medical and 
study records for verification of the data and/or clinical study procedures. Access to this 
information will be permitted to representatives of the aforementioned organizations to the 
extent permitted by law.

10.12 Data Generation and Analysis 
After data have been entered into the study EDC system database, a system of computerized 
data validation checks will be implemented and applied to the database.  Query reports 
pertaining to data omissions and discrepancies will be forwarded to the clinical Investigator 
and the Sponsor for resolution.  Where required, the Investigator will be asked for 
supplementary information through a query.  The study EDC system database will be 
updated by the clinical investigator or their staff, in accordance with the resolved query 
reports.  All changes to the study database will be documented.   
Once the eCRFs are monitored in the EDC system, the data management CRO and the 
Sponsor will further check the eCRFs for completeness and plausibility of the data. The data 
management CRO will use quality systems in order to verify accurate and complete data 
entry, including additional checks of the data once entered in a database 
(eg, range checks, cross checks and other edit checks).  
All procedures for the handling and analysis of data will be conducted using good computing 
practices meeting ICH and US Food and Drug Administration (FDA) guidelines for the 
handling and analysis of data for clinical trials.  Data will be checked per the data 
management CRO’s SOPs. The database then will be locked and a biostatistician will 
complete the analyses of the data in accordance with the Statistical Analysis Plan. 
10.13 Retention of Data 
Archived versions of the EDC system database will be saved by the Sponsor consistent with 
ICH Good Clinical Practices Guidelines.  The Sponsor will notify the investigator when 
documents should be returned.   
The Investigator’s site and the study clinical laboratory will retain all records related to the 
study in compliance with ICH Good Clinical Practices Guidelines and 21 CFR 312.57(c)  
(see Appendix 5 for additional investigator obligations).  
10.14 Financial Disclosure 
The Principal Investigator and Sub-investigators (as listed on Form FDA 1572) will provide 
financial disclosure information prior to participation in the study. The Principal Investigator 
and any Sub-investigators will notify the Sponsor promptly of any required revision to their 
financial disclosure status during the term of this study, annually, or at the end of the study 
(if applicable). The Principal Investigator and Sub-investigators will provide updated 
financial disclosure information upon the Sponsor’s written request following completion of 
the study. 
10.15 Publication and Disclosure Policy 
Aerie Pharmaceuticals, as the Sponsor, has proprietary interest in the study. Authorship and 
manuscript composition will reflect joint cooperation between multiple investigators and 
sites and Aerie Pharmaceuticals personnel.  As this study involves multiple centers, no

FULL PRESCRIBING INFORMATION 
1 INDICATIONS AND USAGE 
Latanoprost Sterile Ophthalmic Solution is indicated for the reduction of elevated intraocular 
pressure in patients with open-angle glaucoma or ocular hypertension. 
2 DOSAGE AND ADMINISTRATION 
The recommended dosage is one drop in the affected eye(s) once daily in the evening. If one 
dose is missed, treatment should continue with the next dose as normal.   
The dosage of latanoprost ophthalmic solution should not exceed once daily; the combined 
use of two or more prostaglandins, or prostaglandin analogs including latanoprost is not 
recommended. It has been shown that administration of these prostaglandin drug products 
more than once daily may decrease the intraocular pressure (IOP) lowering effect or cause 
paradoxical elevations in IOP.   
Reduction of the IOP starts approximately 3 to 4 hours after administration and the maximum 
effect is reached after 8 to 12 hours.   
Latanoprost ophthalmic solution may be used concomitantly with other topical ophthalmic 
drug products to lower IOP.  If more than one topical ophthalmic drug is being used, the 
drugs should be administered at least five (5) minutes apart.  Contact lenses should be 
removed prior to the administration of latanoprost ophthalmic solution, and may be 
reinserted 15 minutes after administration. 
3 DOSAGE FORMS AND STRENGTHS 
Sterile ophthalmic solution containing 50 mcg/mL latanoprost. 
4 CONTRAINDICATIONS 
Known hypersensitivity to latanoprost, benzalkonium chloride, or any other ingredients in 
this product. 
5 WARNINGS AND PRECAUTIONS 
5.1 Pigmentation 
Latanoprost has been reported to cause changes to pigmented tissues. The most frequently 
reported changes have been increased pigmentation of the iris, periorbital tissue (eyelid), and 
eyelashes. Pigmentation is expected to increase as long as latanoprost is administered. 
The pigmentation change is due to increased melanin content in the melanocytes rather than 
to an increase in the number of melanocytes. After discontinuation of latanoprost, 
pigmentation of the iris is likely to be permanent, while pigmentation of the periorbital tissue 
and eyelash changes have been reported to be reversible in some patients. Patients who 
receive treatment should be informed of the possibility of increased pigmentation. Beyond 5 
years the effects of increased pigmentation are not known [see Clinical Studies (14.2)]. 
Iris color change may not be noticeable for several months to years. Typically, the brown 
pigmentation around the pupil spreads concentrically towards the periphery of the iris and 

PG324 Ophthalmic Solution 
Clinical Study Protocol: PG324-CS301, Amendment 4

Page 108 of 123 
 
the entire iris or parts of the iris become more brownish.  Neither nevi nor freckles of the iris 
appear to be affected by treatment. While treatment with latanoprost can be continued in 
patients who develop noticeably increased iris pigmentation, these patients should be 
examined regularly [see Patient Counseling Information (17.1)]. 
5.2 Eyelash Changes 
Latanoprost may gradually change eyelashes and vellus hair in the treated eye; these changes 
include increased length, thickness, pigmentation, the number of lashes or hairs, and 
misdirected growth of eyelashes. Eyelash changes are usually reversible upon 
discontinuation of treatment [see Patient Counseling Information (17.2)]. 
5.3 Intraocular Inflammation 
Latanoprost should be used with caution in patients with a history of intraocular 
inflammation (iritis/uveitis) and should generally not be used in patients with active 
intraocular inflammation because inflammation may be exacerbated. 
5.4 Macular Edema 
Macular edema, including cystoid macular edema, has been reported during treatment with 
latanoprost. Latanoprost ophthalmic solution should be used with caution in aphakic 
patients, in pseudophakic patients with a torn posterior lens capsule, or in patients with 
known risk factors for macular edema. 
5.5 Herpetic Keratitis 
Reactivation of Herpes Simplex keratitis has been reported during treatment with latanoprost 
ophthalmic solution.  Latanoprost should be used with caution in patients with a history of 
herpetic keratitis. Latanoprost should be avoided in cases of active herpes simplex keratitis 
because inflammation may be exacerbated. 
5.6 Bacterial Keratitis 
There have been reports of bacterial keratitis associated with the use of multiple-dose 
containers of topical ophthalmic products. These containers had been inadvertently 
contaminated by patients who, in most cases, had a concurrent corneal disease or a disruption 
of the ocular epithelial surface [see Patient Counseling Information (17.3)]. 
5.7 Use with Contact Lenses 
Contact lenses should be removed prior to the administration of latanoprost ophthalmic 
solution, and may be reinserted 15 minutes after administration. 
6 ADVERSE REACTIONS 
The following adverse reactions were reported in postmarketing experience and are discussed 
in greater detail in other sections of the label: 
• Iris pigmentation changes [see Warnings and Precautions (5.1)] 
• Eyelid skin darkening [see Warnings and Precautions (5.1)] 
• Eyelash changes (increased length, thickness, pigmentation, and number of lashes) [see   
Warnings and Precautions (5.2)] 
• Intraocular inflammation (iritis/uveitis) [see Warnings and Precautions (5.3)]

• Macular edema, including cystoid macular edema [see Warnings and Precautions (5.4)] 
6.1 Clinical Trials Experience 
Because clinical trials are conducted under widely varying conditions, the adverse reaction 
rates observed in the clinical studies of a drug cannot be directly compared to rates in the 
clinical trials of another drug and may not reflect the rates observed in clinical practice. 
Latanoprost was studied in three multicenter, randomized, controlled clinical trials. Patients 
received 50 mcg/mL latanoprost once daily or 5 mg/mL active-comparator (timolol) 
twice daily. The patient population studied had a mean age of 65±10 years. Seven percent of 
patients withdrew before the 6-month endpoint.

Less than 1% of the patients treated with latanoprost required discontinuation of therapy 
because of intolerance to conjunctival hyperemia. 
6.2 Postmarketing Experience 
The following reactions have been identified during postmarketing use of latanoprost in 
clinical practice. Because they are reported voluntarily from a population of unknown size, 
estimates of frequency cannot be made. The reactions, which have been chosen for inclusion 
due to either their seriousness, frequency of reporting, possible causal connection to 
latanoprost, or a combination of these factors, include: 
Nervous System Disorders: dizziness, headache, and toxic epidermal necrolysis 
Eye Disorders: eyelash and vellus hair changes (increased length, thickness, pigmentation, 
and number); keratitis; corneal edema and erosions; intraocular inflammation (iritis/uveitis); 
macular edema, including cystoid macular edema; misdirected eyelashes sometimes resulting 
in eye irritation; periorbital and lid changes resulting in deepening of the eyelid sulcus. 
Respiratory, Thoracic and Mediastinal Disorders: asthma and exacerbation of asthma; 
dyspnea

7 DRUG INTERACTIONS 
In vitro studies have shown that precipitation occurs when eye drops containing thimerosal 
are mixed with latanoprost.  If such drugs are used, they should be administered at least five 
(5) minutes apart.  
The combined use of two or more prostaglandins, or prostaglandin analogs including 
latanoprost is not recommended. It has been shown that administration of these prostaglandin 
drug products more than once daily may decrease the IOP lowering effect or cause 
paradoxical elevations in IOP. 
8 USE IN SPECIFIC POPULATIONS 
8.1 Pregnancy 
Teratogenic Effects: Pregnancy Category C. 

PG324 Ophthalmic Solution 
Clinical Study Protocol: PG324-CS301, Amendment 4 
Aerie Pharmaceuticals, Inc.

Reproduction studies have been performed in rats and rabbits.  In rabbits, an incidence of 4 
of 16 dams had no viable fetuses at a dose that was approximately 80 times the maximum 
human dose, and the highest nonembryocidal dose in rabbits was approximately 15 times the 
maximum human dose. 
There are no adequate and well-controlled studies in pregnant women. Latanoprost should be 
used during pregnancy only if the potential benefit justifies the potential risk to the fetus. 
8.3 Nursing Mothers 
It is not known whether this drug or its metabolites are excreted in human milk. Because 
many drugs are excreted in human milk, caution should be exercised when latanoprost is 
administered to a nursing woman. 
8.4 Pediatric Use 
Safety and effectiveness in pediatric patients have not been established. 
8.5 Geriatric Use 
No overall differences in safety or effectiveness have been observed between elderly and 
younger patients. 
10 OVERDOSAGE 
Intravenous infusion of up to 3 mcg/kg in healthy volunteers produced mean plasma 
concentrations 200 times higher than during clinical treatment and no adverse reactions were 
observed.  Intravenous dosages of 5.5 to 10 mcg/kg caused abdominal pain, dizziness, 
fatigue, hot flushes, nausea, and sweating.  If overdosage with latanoprost occurs, treatment 
should be symptomatic. 
11 DESCRIPTION 
Latanoprost is a prostaglandin F2α analogue. Its chemical name is isopropyl-(Z)-
7[(1R,2R,3R,5S)3,5-dihydroxy-2-[(3R)-3-hydroxy-5-phenylpentyl]cyclopentyl]-5-
heptenoate. Its molecular formula is C26H40O5 and its chemical structure is: 
 
 
 
Latanoprost is a colorless to slightly yellow oil that is very soluble in acetonitrile and freely 
soluble in acetone, ethanol, ethyl acetate, isopropanol, methanol, and octanol. It is practically 
insoluble in water. 
Latanoprost ophthalmic solution 0.005% is supplied as a sterile, isotonic, buffered aqueous 
solution of latanoprost with a pH of approximately 6.7 and an osmolality of approximately 

PG324 Ophthalmic Solution 
Clinical Study Protocol: PG324-CS301, Amendment 4

Page 112 of 123 
 
267 mOsmol/kg.  Each mL of Latanoprost ophthalmic solution contains 50 micrograms of 
latanoprost.  Benzalkonium chloride, 0.02% is added as a preservative.  The inactive 
ingredients are: sodium chloride, sodium dihydrogen phosphate monohydrate, disodium 
hydrogen phosphate anhydrous, and water for injection.  One drop contains approximately 
1.5 mcg of latanoprost. 
12 CLINICAL PHARMACOLOGY 
12.1 Mechanism of Action 
Latanoprost is a prostanoid selective FP receptor agonist that 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. 
Elevated IOP represents a major risk factor for glaucomatous field loss. The higher the 
level of IOP, the greater the likelihood of optic nerve damage and visual field loss. 
12.2 Pharmacodynamics 
Reduction of the IOP in man starts about 3–4 hours after administration and maximum effect 
is reached after 8–12 hours. IOP reduction is present for at least 24 hours. 
12.3 Pharmacokinetics 
Absorption 
Latanoprost is absorbed through the cornea where the isopropyl ester prodrug is hydrolyzed 
to the acid form to become biologically active. 
Distribution 
The distribution volume in humans is 0.16 ± 0.02 L/kg. The acid of latanoprost can be 
measured in aqueous humor during the first 4 hours, and in plasma only during the first 
hour after local administration. Studies in man indicate that the peak concentration in the 
aqueous humor is reached about two hours after topical administration. 
Metabolism 
Latanoprost, an isopropyl ester prodrug, is hydrolyzed by esterases in the cornea to the 
biologically active acid. The active acid of latanoprost reaching the systemic circulation 
is primarily metabolized by the liver to the 1,2-dinor and 1,2,3,4-tetranor metabolites via 
fatty acid β-oxidation. 
Excretion 
The elimination of the acid of latanoprost from human plasma is rapid (t1/2 = 17 min) after 
both intravenous and topical administration. Systemic clearance is approximately 
7 mL/min/kg. Following hepatic β-oxidation, the metabolites are mainly eliminated via the 
kidneys. Approximately 88% and 98% of the administered dose are recovered in the urine 
after topical and intravenous dosing, respectively.

13 NONCLINICAL TOXICOLOGY 
13.1 Carcinogenesis, Mutagenesis, Impairment of Fertility 
Latanoprost was not carcinogenic in either mice or rats when administered by oral gavage at 
doses of up to 170 mcg/kg/day (approximately 2800 times the recommended maximum 
human dose) for up to 20 and 24 months, respectively. 
Latanoprost was not mutagenic in bacteria, in mouse lymphoma, or in mouse micronucleus 
tests. Chromosome aberrations were observed in vitro with human lymphocytes.  Additional 
in vitro and in vivo studies on unscheduled DNA synthesis in rats were negative. 
Latanoprost has not been found to have any effect on male or female fertility in animal 
studies. 
14 CLINICAL STUDIES 
14.1 Elevated Baseline IOP 
Patients with mean baseline IOP of 24 – 25 mmHg who were treated for 6 months in multi-
center, randomized, controlled trials demonstrated 6 – 8 mmHg reductions in IOP. This IOP 
reduction with latanoprost 0.005% dosed once daily was equivalent to the effect of timolol 
0.5% dosed twice daily. 
14.2 Progression of Increased Iris Pigmentation 
A 3-year open-label, prospective safety study with a 2-year extension phase was conducted to 
evaluate the progression of increased iris pigmentation with continuous use of latanoprost 
once-daily as adjunctive therapy in 519 patients with open-angle glaucoma. The analysis was 
based on observed-cases population of the 380 patients who continued in the extension 
phase.  Results showed that the onset of noticeable increased iris pigmentation occurred 
within the first year of treatment for the majority of the patients who developed noticeable 
increased iris pigmentation. Patients continued to show signs of increasing iris pigmentation 
throughout the five years of the study. Observation of increased iris pigmentation did not 
affect the incidence, nature, or severity of adverse events (other than increased iris 
pigmentation) recorded in the study.  IOP reduction was similar regardless of the 
development of increased iris pigmentation during the study.

17 PATIENT COUNSELING INFORMATION 
17.1 Potential for Pigmentation 
Advise patients about the potential for increased brown pigmentation of the iris, which may 
be permanent. Inform patients about the possibility of eyelid skin darkening, which may be 
reversible after discontinuation of Latanoprost ophthalmic solution [see Warnings and 
Precautions (5.1)]. 
17.2 Potential for Eyelash Changes 
Inform patients of the possibility of eyelash and vellus hair changes in the treated eye during 
treatment with Latanoprost ophthalmic solution. These changes may result in a disparity 
between eyes in length, thickness, pigmentation, number of eyelashes or vellus hairs, and/or 
direction of eyelash growth.  Eyelash changes are usually reversible upon discontinuation 
of treatment. 
17.3 Handling the Container 
Instruct patients to avoid allowing the tip of the dispensing container to contact the eye or 
surrounding structures because this could cause the tip to become contaminated by 
common bacteria known to cause ocular infections. Serious damage to the eye and 
subsequent loss of vision may result from using contaminated solutions [see Warnings and 
Precautions (5.6)]. 
17.4 When to Seek Physician Advice 
Advise patients that if they develop an intercurrent ocular condition (e.g., trauma or 
infection) or have ocular surgery, or develop any ocular reactions, particularly conjunctivitis 
and eyelid reactions, they should immediately seek their physician’s advice concerning the 
continued use of the multiple-dose container. 
17.5 Use with Contact Lenses 
Advise patients that Latanoprost ophthalmic solution contains benzalkonium chloride, which 
may be absorbed by contact lenses. Contact lenses should be removed prior to administration 
of the solution. Lenses may be reinserted 15 minutes following administration of Latanoprost 
ophthalmic solution. 
17.6 Use with Other Ophthalmic Drugs 
If more than one topical ophthalmic drug is being used, the drugs should be administered at 
least five (5) minutes apart.

Appendix 5 
Investigator’s Obligations 
The Investigator is obligated to: 
1. In the event of a serious adverse experience, whether related to the use of the study 
medication or device or not, or the death of a subject, the Investigator is responsible for 
notifying the Sponsor Safety Officer immediately (see Section 6.9, Adverse events). 
The Investigator must also notify the Sponsor Representative and the Institutional 
Review Board (IRB) to which he/she is responsible. 
2. Prior to initiating the study, sign and return to the Sponsor Representative, the relevant 
form (Statement of Investigator form provided by the Sponsor for studies involving 
non-significant risk devices, or OTC drugs; or an FDA No. 1572 is required for IND 
Phase I, II, III and IV studies). Each sub-Investigator who will assist in the study is to be 
identified in the required form. The current curriculum vitae (signed and dated) of the 
principal Investigator and of each sub-Investigator named in the Statement of Investigator 
form or 1572 form is to accompany the form.  
3. Cooperate with the Sponsor on the preparation of an FDA Form No. 3454 
(Certification: Financial Interests and Arrangements of Clinical Investigators) or 3455 
(Disclosure: Financial Interests and Arrangements of Clinical Investigators).  
4. Obtain and submit to the Sponsor a copy of his/her IRB approval of the protocol prior to 
initiating the study. 
5. Obtain signed informed consent from each subject or his/her legal guardian prior to 
acceptance of the subject into the study. 
6. Read, and agree to adhere to the study protocol prior to the initiation of the study. 
Deviations from the study protocol are not to be implemented without the prior written 
approval of the Sponsor and IRB, unless protection of the safety and welfare of study 
subjects requires prompt action. During the study, if the Investigator feels that in his/her 
clinical judgment, it is necessary to promptly terminate one or more subjects from the 
study, or to promptly implement reasonable alternatives to, or deviations from the 
protocol in consideration of the safety of study subjects, the Sponsor is to be notified of 
these terminations, alternatives, and deviations, and the reasons for such changes are to 
be documented in the study records. The Investigator is to also notify his/her IRB of any 
such changes. 
7. Accurately record, at the Investigator’s site, all required data on each subject's electronic 
Case Report Form.

Appendix 6 
Declaration of Helsinki 
Recommendations Guiding Medical Doctors in Biomedical Research Involving Human 
Subjects 
I. BASIC PRINCIPLES 
1. Biomedical research involving human subjects must conform to generally accepted 
scientific principles and should be based on adequately performed laboratory and animal 
experimentation and on a thorough knowledge of the scientific literature. 
2. The design and performance of each experimental procedure involving human subjects 
should be clearly formulated in an experimental protocol which should be transmitted to 
a specially appointed independent committee for consideration, comment and guidance. 
3. Biomedical research involving human subjects should be conducted only by scientifically 
qualified persons and under the supervision of a clinically competent medical person. 
The responsibility for the human subject must always rest with a medically qualified 
person and never rest with the subject of the research, even though the subject has given 
his or her consent. 
4. Biomedical research involving human subjects cannot legitimately be carried out unless 
the importance of the objective is in proportion to the inherent risk to the subject. 
5. Every biomedical research project involving human subjects should be preceded by 
careful assessment of predictable risks in comparison with foreseeable benefits to the 
subject or to others. Concern for the interests of the subject must always prevail over the 
interests of science and society. 
6. The right of the research subject to safeguard his or her integrity must always be 
respected. Every precaution should be taken to respect the privacy of the subject and to 
minimize the impact of the study on the subject's physical and mental integrity and on the 
personality of the subject. 
7. Doctors should abstain from engaging in research projects involving human subjects 
unless they are satisfied that the hazards involved are believed to be predictable. 
Doctors should cease any investigation if the hazards are found to outweigh the potential 
benefits. 
8. In publication of the results of his or her research, the doctor is obliged to preserve the 
accuracy of the results. Reports of experimentation not in accordance with the principles 
laid down in this Declaration should not be accepted for publication. 
9. In any research on human beings, each potential subject must be adequately informed of 
the aims, methods, anticipated benefits and potential hazards of the study and the 
discomfort it may entail. He or she should be informed that he or she is at liberty to 

PG324 Ophthalmic Solution 
Clinical Study Protocol: PG324-CS301, Amendment 4 
Aerie Pharmaceuticals, Inc. 
 
Confidential 
Page 120 of 123 
 
abstain from participation in the study and that he or she is free to withdraw his or her 
consent to participation at any time. The doctor should then obtain the subject's given 
informed consent, preferably in writing. 
10. When obtaining informed consent for the research project the doctor should be 
particularly cautious if the subject is in a dependent relationship to him or her or may 
consent under duress. In that case, the informed consent should be obtained by a doctor 
who is not engaged in the investigation and who is completely independent of this official 
relationship. 
11. In case of legal incompetence, informed consent should be obtained from the legal 
guardian in accordance with national legislation. Where physical or mental incapacity 
makes it impossible to obtain informed consent, or when the subject is a minor, 
permission from the responsible relative replaces that of the subject in accordance with 
national legislation. 
12. The research protocol should always contain a statement of the ethical considerations 
involved and should indicate that the principles enunciated in the present Declaration are 
complied with. 
II. MEDICAL RESEARCH COMBINED WITH PROFESSIONAL CARE 
(CLINICAL RESEARCH) 
13. In the treatment of the sick person, the doctor must be free to use a new diagnostic and 
therapeutic measure, if in his or her judgment it offers hope of saving life, reestablishing 
health or alleviating suffering. 
14. The potential benefits, hazards and discomforts of a new method should be weighed 
against the advantages of the best current diagnostic and therapeutic methods. 
15. In any medical study, all subjects - including those of a control group, if any, should be 
assured of the best proven diagnostic and therapeutic methods. 
16. The refusal of the subject to participate in a study must never interfere with the 
doctor-subject relationship. 
17. If the doctor considers it essential not to obtain informed consent, the specific reasons for 
this proposal should be stated in the experimental protocol for transmission to the 
independent committee. 
18. The doctor can combine medical research with professional care, the objective being the 
acquisition of new medical knowledge, only to the extent that medical research is 
justified by its potential diagnostic or therapeutic value for the subject.

III. NON-THERAPEUTIC BIOMEDICAL RESEARCH INVOLVING HUMAN 
SUBJECT (NONCLINICAL BIOMEDICAL RESEARCH) 
19. In the purely scientific application of medical research carried out on a human being, it is 
the duty of the doctor to remain the protector of the life and health of that person on 
whom biomedical research is being carried out. 
20. The subjects should be volunteers - either healthy person or subjects for whom the 
experimental design is not related to the subject's illness. 
21. The Investigator or the team should discontinue the research if in his/her or their 
judgment it may, if continued, be harmful to the individual.  
22. In research on man, the interest of science and society should never take precedence over 
consideration related to the well-being of the subject.
