9.7 
Study Termination  
The study may be stopped at any time by the Investigator and/or Ora after consultation with 
the Sponsor, with appropriate notification.  
9.8 
Study Duration  
An individual subject’s participation will involve 5 visits over approximately 4-weeks (28 
days) 
9.9 
Monitoring and Quality Assurance  
During the course of the study a monitor, or designee, will make routine site visits to review 
protocol compliance, assess study drug accountability, subject safety, and ensure the study is 
being conducted according to the pertinent regulatory requirements.  The review of the 
subjects’ medical records will be performed in a manner that adequately maintains subject 
confidentiality.  A monitoring plan will outline further details of the study monitoring. 
Regulatory authorities of domestic and foreign agencies, Sponsor quality assurance, 
 
quality assurance and or its designees may carry out on-site inspections and/or audits, which 
may include source data checks.  Therefore, direct access to the original source data will be 
required for inspections and/or audits.  All inspections and audits will be carried out giving 
consideration to data protection as well as subject confidentiality to the extent that local, 
state, and federal laws apply. 
10 SAFETY DEFINITIONS, SAFETY MONITORING AND 
REPORTING 
10.1 Adverse Event 
An adverse event (AE) is defined as any untoward medical occurrence associated with the 
use of a drug in humans, whether or not the event is considered drug-related.  An AE can 
therefore be any unfavorable and unintended sign (e.g., an abnormal laboratory finding), 
symptom, or disease occurring after the subject started dosing with the study drug, without 
any judgment about causality.  Any pre-existing medical condition that worsens after 
administration of the study drug will also be considered a new AE.   
Study drug includes the investigational drug under evaluation and placebo. 
Documentation regarding the AE should be made as to the nature, date of onset, end date, 
severity, relationship to study drug, action(s) taken, seriousness, and outcome of any sign or 
symptom observed by the Investigator or reported by the subject upon indirect questioning. 
10.1.1 Severity 
Severity of an AE is defined as a qualitative assessment of the degree of intensity of an AE as 
determined by the investigator or reported to him/her by the patient/subject.  The assessment 

OC-02 Nasal Spray 
Sponsor: Oyster Point Pharma, Inc.  
Clinical Trial Protocol #OPP-003 
July 11, 2018 
 
CONFIDENTIAL 
Page 39 of 65 
 
of severity is made irrespective of relationship to study drug or seriousness of the event and 
should be evaluated according to the following scale: 
x Mild:  
Event is noticeable to the subject, but is easily tolerated and does not 
interfere with the subject’s daily activities. 
x Moderate: Event is bothersome, possibly requiring additional therapy, and may 
interfere with the subject’s daily activities. 
x Severe: 
Event is intolerable, necessitates additional therapy or alteration of 
therapy, and interferes with the subject’s daily activities. 
10.1.2 Relationship to Study Drug 
The relationship of each AE to the investigational product should be determined by the 
investigator (in a blinded manner) using these explanations: 
x Definite: When there are good reason and sufficient documentation to demonstrate a 
direct causal relationship between investigational product and AE 
x Probable: When there are good reasons and sufficient documentation to assume a 
causal relationship in the sense of plausible, conceivable, likely but not 
necessarily highly probable 
x Possible: When there is sufficient information to accept the possibility of a causal 
relationship in the sense of not impossible and not unlikely, although the 
connection is uncertain or doubtful, for example; due to missing data or 
insufficient evidence. 
x None: 
When there is sufficient information to accept a lack of a causal 
relationship, in the sense of impossible and improbable. 
x Unclassified: When the causal relationship is not assessable for whatever reason due 
to insufficient evidence, conflicting data or poor documentation. 
10.1.3 Expectedness 
The expectedness of an AE should be determined based upon existing safety information 
about the study drug using these explanations: 
x Unexpected: An AE that is not listed in the Investigator’s Brochure (IB) or is not 
listed at the specificity or severity that has been observed. 
x Expected: An AE that is listed in the IB at the specificity and severity that has been 
observed. 
x Not Applicable: Any AE that is unrelated to the study drug. 
AEs that are mentioned in the IB 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 are to be considered unexpected. 
The investigator should initially classify the expectedness of an AE, but the final 
classification is subject to the Medical Monitor’s determination.

10.2 Serious Adverse Events 
An AE is considered “serious” (SAE) if, in the view of either the investigator or Sponsor, it 
results in any of the following outcomes: 
x Death 
 
x A life-threatening AE 
Note: An AE is considered “life-threatening” if, in the view of either the investigator 
or Sponsor, its occurrence places the patient or subject at immediate risk of death.  It 
does not include an AE that, had it occurred in a more severe form, might have 
caused death. 
x Inpatient hospitalization or prolongation of existing hospitalization 
Note: The term “inpatient hospitalization” refers to any inpatient admission (even if 
less than 24 hours).  For chronic or long-term inpatients, inpatient admission includes 
transfer within the hospital to an acute/intensive care inpatient unit.  Inpatient 
hospitalization does not include:  emergency room visits; outpatient/same-
day/ambulatory procedures; observation/short stay units; rehabilitation facilities; 
hospice facilities; nursing homes; or clinical research/phase 1 units. 
Note:  The term “prolongation of existing hospitalization” refers to any extension of 
an inpatient hospitalization beyond the stay anticipated or required for the reason for 
the initial admission as determined by the investigator or treating physician. 
x A persistent or significant incapacity or substantial disruption of the ability to conduct 
normal life functions 
Note:  An SAE specifically related to visual threat would be interpreted as any 
potential impairment or damage to the subject’s eyes (e.g., hemorrhage, retinal 
detachment, central corneal ulcer or damage to the optic nerve). 
x A congenital anomaly/birth defect in an offspring of a study subject. 
Important medical events that may not result in death, are life-threatening, or require 
hospitalization may be considered serious when, based upon appropriate medical judgment, 
they may jeopardize the patient or subject and may require medical or surgical intervention to 
prevent one of the outcomes listed in this definition. 
10.3 Procedures for Reporting Adverse Events  
All AEs and their outcomes must be reported to Ora, the Sponsor, and the IRB/IEC as 
required by the IRB/IEC, federal, state, or local regulations and governing health authorities 
and recorded on the appropriate eCRF.

10.3.1 Reporting a Suspected Unexpected Adverse Reaction  
All AEs that are ‘suspected’ and ‘unexpected’ are to be reported to Ora, the Sponsor and the 
IRB/IEC as required by the IRB/IEC, federal, state, or local regulations and governing health 
authorities. 
10.3.2 Reporting a Serious Adverse Event 
To ensure subject safety, all SAEs, regardless of relationship to the study drug, must be 
immediately reported.  All information relevant to the SAE must be recorded on the 
appropriate CRFs.  The investigator is obligated to pursue and obtain information requested 
by 
 the Sponsor in addition to that information reported on the CRF.  All subjects 
experiencing a SAE must be followed up and the outcome reported. 
In the event of a SAE, the investigator must notify 
 the Sponsor immediately; obtain 
and maintain in his/her files all pertinent medical records, information, and medical 
judgments from colleagues who assisted in the treatment and follow-up of the subject; 
provide 
the Sponsor with a complete case history, which includes a statement as to 
whether the event was or was not suspected to be related to the use of the study drug; and 
inform the IRB of the SAE within their guidelines for reporting SAEs.

10.4 Procedures for Unmasking of Study Drug 
All subjects, investigators, and study personnel involved with the conduct of the study will be 
masked with regard to treatment assignments. When medically necessary, the investigator 
may need to determine what treatment regimen has been assigned to a subject. When 
possible (i.e., in non-emergent situations), 
 the Sponsor should be notified before 
unmasking study drug. The unmasked subject will continue the study if warranted by the 
Investigator in consultation with the Medical Monitor.

11.2.2 Safety Population 
The safety population will include all randomized subjects who received at least one dose of 
the study drug. Analysis on the safety population will group subjects according to the 
treatment actually received.  
11.4.1 General Considerations 
Quantitative variables will be summarized using the number of subjects (n), mean, SD, 
median, 25th and 75th percentiles, and minimum and maximum. Qualitative variables will be 
summarized using counts and percentages. 
All summaries will be presented by treatment group. Summaries will be provided for 
demographics, medical history, concomitant medications, and subject disposition. 
For the summaries, medical history, concomitant medications, and AEs will be coded to 
MedDRA and World Health Organization Drug dictionaries, as appropriate. 
Baseline measures are defined as the last measure prior to the initiation of study treatment, 
usually at Visit 1 screening. 
11.4.2 Unit of Analysis 
For efficacy endpoints, the unit of analysis will be the study eye as defined as the eye that 
meets all inclusion and exclusion criteria. If both eyes qualify, then the study eye will be the 
eye with the greatest increase in tear production with stimulation by a cotton swab at the 
Screening Visit. If there is no difference in stimulated tear production, the eye with the lower 
basal Schirmer’s score at screening. If there is no difference for either measure, the right eye 
will be used as the study eye. 
For safety endpoints, both eyes will be analyzed.

and the number of subjects with events (along with percentages) by treatment group for 
TEAEs in several categories base on seriousness, relationship to treatment, and severity.  
Other safety endpoints including visual acuity, slit-lamp biomicroscopy and intranasal 
examination will be summarized by treatment group and visit using descriptive statistics. 
Changes or shifts from baseline will be summarized where appropriate. For assessments 
performed by eye, study eye and fellow eye will be summarized separately. In addition, shifts 
from baseline to worst on-treatment value for ocular safety assessments will be summarized. 
The SAP will present methods of analysis of these defined parameters in detail. 
11.4.8 Interim Analysis 
No interim analysis planned for this study. 
12 COMPLIANCE WITH GOOD CLINICAL PRACTICES, ETHICAL 
CONSIDERATIONS, AND ADMINISTRATIVE ISSUES  
This study will be conducted in compliance with the protocol, Good Clinical Practices, 
including the International Conference on Harmonization (ICH) Guidelines, and in general, 
consistent with the Declaration of Helsinki.  In addition, all applicable local, state, and 
federal requirements relevant to the use of study drugs in the countries involved will be 
adhered to. 
12.1 Protection of Human Subjects 
12.1.1  Subject Informed Consent  
Informed consent/assent must take place before any study specific procedures are initiated.  
Signed and dated written informed consent must be obtained from each subject and/or from 
the subject’s parent or legal guardian prior to enrollment into the study.  If the subject is 
under the legal age of consent, the consent form must be signed by a legal guardian or as 
required by state and/or local laws and regulations. 
All informed consent/assent forms must be approved for use by the Sponsor and receive 
approval/favorable opinion from an IRB prior to their use.  If the consent form requires 
revision (e.g., due to a protocol amendment or significant new safety information), it is the 
investigator’s responsibility to ensure that the amended informed consent is reviewed and 
approved by Ora prior to submission to the governing IRB and that it is read, signed and 
dated by all subjects subsequently enrolled in the study as well as those currently enrolled in 
the study. 
If informed consent is taken under special circumstances (oral informed consent), then the 
procedures to be followed must be determined by 
Sponsor and provided in 
writing by 
 Sponsor prior to the consent process.

the Sponsor, the IRB 
approving this study, the Food and Drug Administration, the Department of Health and 
Human Services, 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 trial procedures.  Access to this information will be 
permitted to the aforementioned individuals to the extent permitted by law. 
A report of the results of this study may be published or sent to the appropriate health 
authorities in any country in which the study drug may ultimately be marketed, but the 
subject’s identity will not be disclosed in these documents. 
12.4 Documentation  
Source documents may include a subject’s medical records, hospital charts, clinic charts, the 
investigator’s study subject files, as well as the results of diagnostic tests such as X-rays, 
laboratory tests, and electrocardiograms.  The investigator’s copy of the CRFs serves as the 
investigator’s record of a subject’s study-related data. 
12.4.1  Retention of Documentation  
All study related correspondence, subject records, consent forms, record of the distribution 
and use of all study drug and copies of CRFs should be maintained on file for at least two 
years after the last approval of a marketing application in an ICH region and until there are 
no pending or contemplated marketing applications in an ICH region; or until at least two 
years have elapsed since the formal discontinuation of clinical development of the study 
drug. These documents will be retained for a longer period if required by the applicable 
regulatory requirements or by an agreement with the Sponsor.  It is the responsibility of the

APPENDIX 2: EXAMINATION PROCEDURES, TESTS, EQUIPMENT, 
AND TECHNIQUES  
The following examination procedures, tests, equipment and techniques are listed in this 
Appendix:  
Visual Acuity Procedures  
LogMAR visual acuity must be assessed using an ETDRS chart. The procedure used will be 
consistent with the recommendations provided for using the ETDRS eye chart. Visual acuity 
should be evaluated at the beginning of each visit in the study (i.e., prior to slit lamp 
examination). Participants should use the most recent correction to attain their corrected 
distance visual acuity (CDVA); if they forget their spectacles, this prescription can be placed 
in a trial frame. 
Equipment 
The visual acuity chart to be used is the ETDRS chart. If smaller reproduction (18" by 18", 
e.g., from Prevent Blindness) wall charts are used, the participant viewing distance should be 
exactly 10 feet (or as specified by the manufacturer). In ALL cases, for purposes of 
standardizing the testing conditions during the study, all sites must use only ETDRS Series 
2000 Chart 1 & 2, and the right eye should be tested first. For reflectance (wall) charts, the 
chart should be placed frontally and be well illuminated. 
Measurement Technique 
The chart should be at a comfortable viewing angle. The right eye should be tested first. The 
participant should attempt to read each letter, line-by-line, left to right, beginning with line 1 
at the top of the chart. The participant should be told that the chart has letters only, no 
numbers. If the participant reads a number, s/he should be reminded that the chart contains 
no numbers, and the examiner should then request a letter in lieu of the number. The 
participant should be asked to read slowly, so as to achieve the best identification of each 
letter. S/he is not to proceed to the next letter until s/he has given a definite response. 
If the participant changes a response (e.g., 'that was a "C" not an "O"') before s/he has read 
aloud the next letter, then the change must be accepted. If the participant changes a response 
having read the next letter, then the change is not accepted. The examiner should never point 
to the chart or to specific letters on the chart during the test. 
A maximum effort should be made to identify each letter on the chart. When the participant 
says s/he cannot read a letter, s/he should be encouraged to guess. If the participant identifies 
a letter as one of two letters, s/he should be asked to choose one letter and, if necessary, to 
guess. When it becomes evident that no further meaningful readings can be made, despite 
encouragement to read or guess, the examiner should stop the test for that eye. However, all 
letters on the last line should be attempted as letter difficulties vary and the last may be the 
only one read correctly. The number of letters missed or read incorrectly should be noted.

LogMAR Visual Acuity Calculations 
The last line in which a letter is read correctly will be taken as the base logMAR reading. To 
this value will be added the number "N x 0.02" where 'N' represents the total number of 
letters missed up to and including the last line read. This total sum represents the logMAR 
visual acuity for that eye. 
Example: Participant correctly reads 4 of 5 letters on the 0.2 line, and 2 of 5 letters on the 0.1 
line. 
Base logMAR 
= 0.1 
N (total number of letters incorrect on line 0.2 as well as 0.1) 
= 4 
N x T (T=0.02) 
= 0.08 
Base logMAR + (N x T) 
= 0.1 + 0.08 
logMAR visual acuity 
= 0.18 
 
Repeat the procedure for the left eye. 
In order to provide standardized and well-controlled assessments of visual acuity during the 
study, all visual acuity assessments at a single site must be consistently done using the same 
lighting conditions and same correction if possible during the entire study. If the same 
correction cannot be used (i.e., a participant broke his/her glasses), the reason for the change 
in correction should be documented. 
Note: A clinically significant visual acuity decrease (defined as an increase of 0.22 or greater 
in logMAR score) from the Screening Visit (Visit 1) should be evaluated by the Investigator 
as a potential AE.

Slit Lamp Biomicroscopy  
Slit lamp biomicroscopy will be performed during the study. Observations will be graded as 
Normal or Abnormal. Abnormal findings, which are clinically significant, will be described.  
Corneal Fluorescein Staining  
The examiner should instill 5 PL of 2% preservative-free sodium fluorescein solution into the 
inferior conjunctival cul-de-sac of each eye. Alternatively, corneal staining can be assessed 
using 1.0 mg sodium fluorescein strips. After moistening the tip of the strip with sterile 
buffered saline, the excess is shaken into a waste bin with a sharp flick. The lower lid is then 
pulled down and the flat end of the tip should be gently applied to the inferior tarsal 
conjunctiva with the intent of not inducing reflex tearing and instilling a very small volume 
of dye.  
The participant will be instructed to blink naturally several times without forced closure of 
the eyelid to distribute the fluorescein. In order to achieve maximum fluorescence, the 
examiner should wait at least two minutes after instillation before evaluating corneal 
fluorescein staining. A Wratten #12 yellow filter will be used to enhance the ability to grade 
fluorescein staining. The staining will be graded with the NEI Scale. The upper eyelid is 
lifted slightly to grade the entire corneal surface.

Intranasal Examination  
Qualified participants for the study must undergo an intranasal exam to make the final 
eligibility determination (e.g. severe nasal airway obstruction such as, severe septal deviation 
or inferior turbinate hypertrophy, or vascularized polyp seen on examination are reasons for 
exclusion).  To monitor nasal mucosal integrity during the study for participant safety, an 
examination of the nasal cavities via an intranasal exam will be performed at the Screening 
Visit(after all other screening procedures have been completed) and at Visit 5 or the Early 
Termination Visit.  This examination will be performed by an Ear Nose and Throat (ENT) 
specialist, otolaryngologist or other suitably qualified medical practitioner (i.e. one who has 
been trained to perform intranasal exam).  Still images or video may be captured.  The 
procedure used for the intranasal exam can be conducted either by endoscopic examination 
or nasal specula.

Schirmer’s Test with Topical Anesthesia  
At the Screening Visit, one basal Schirmer’s test will be performed followed by a Schirmer’s 
test with cotton swab nasal stimulation. The Schirmer’s test with topical anesthetic will be 
used to assess tear production using the following steps:   
1. Topical anesthetic drops such as 0.5% proparacaine hydrochloride or equivalent should 
be instilled in both eyes of the participant. 
2. The participant will be instructed to keep the eyes gently closed for one minute.   
3. After opening the eyes and allowing the eyes to recover for approximately one additional 
minute, excess moisture in the inferior fornix is gently removed with a spear. 
4. Schirmer’s strips (35 mm x 5 mm size filter paper strip) will be placed in each eye at the 
junction of the middle and lateral thirds of the lower eye lid.  
5. Under ambient light, the participant will be instructed to look forward and to blink 
normally during the course of the test. The test should be performed in a room with no 
direct air on the participant’s face. 
6. The Schirmer’s strips should remain in place until five minutes have elapsed or both 
strips have reached maximum score. 
7. After five minutes, strips will be removed from both eyes and the amount of wetting will 
be recorded. The strips should be taped to the CRF.   
Schirmer’s test using cotton swab nasal stimulation   
At the Screening Visit, the Schirmer’s test should be performed using cotton swab nasal 
stimulation. New anesthetic drops should be instilled following the same procedure specified 
in steps #1 to 3 above. 
1. With new strips in place, the examiner should insert cotton swabs in the participant’s two 
nostrils simultaneously and gently probe both nasal middle turbinates for approximately 
30 seconds. After this, the examiner can simply hold the swabs in place, applying gentle 
pressure, and repeat probing intermittently as necessary.   
2. Alternatively, the participant can be instructed to hold the cotton swabs and gently probe 
both nasal turbinates simultaneously, resting intermittently before probing again.  The 
examiner should continuously coach the participant on how to perform this test properly.  
3. The Schirmer’s strips should remain in place until five minutes have elapsed or both 
strips have reached maximum score. 
Both Schirmer’s scores will be recorded and verified that they meet the inclusion criteria.
