7.6 
Study Duration 
An individual subject’s participation will involve 2 visits over approximately 6 months.  
 
7.7 
Monitoring and Quality Assurance 
During the course of the study a monitor, or designee, will make routine site visits to review 
protocol compliance, assess 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, 
 
 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. 
8 
SAFETY DEFINITIONS, SAFETY MONITORING AND 
REPORTING 
8.1 
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. 
8.1.1 
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 
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 

OC-01 (varenicline tartrate) Nasal Spray 
Clinical Trial Protocol #OPP-002-01EXT 
Sponsor: Oyster Point Pharma, Inc.

Page 17 of 32 
  
 
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. 
 
8.1.2 
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. 
 
8.1.3 
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.  
 
8.2 
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 

OC-01 (varenicline tartrate) Nasal Spray 
Clinical Trial Protocol #OPP-002-01EXT 
Sponsor: Oyster Point Pharma, Inc. 
January 21, 2019 
CONFIDENTIAL 
Page 18 of 32 
  
 
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. 
 
 
8.3 
Procedures for Reporting Adverse Events 
All AEs and their outcomes must be reported to 
 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. 
8.3.1 
Reporting a Suspected Unexpected Adverse Reaction 
All AEs that are ‘suspected’ and ‘unexpected’ are to be reported to 
 the Sponsor and the 
IRB/IEC as required by the IRB/IEC, federal, state, or local regulations and governing health 
authorities. 
8.3.2 
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 

OC-01 (varenicline tartrate) Nasal Spray 
Clinical Trial Protocol #OPP-002-01EXT 
Sponsor: Oyster Point Pharma, Inc. 
January 21, 2019 
CONFIDENTIAL 
Page 19 of 32 
  
 
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 
 and 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 
and 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. 
Contact information for reporting SAEs: 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
8.4 
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. 
8.5 
Type and Duration of the Follow-up of Subjects after Adverse Events 
The investigator will follow unresolved AEs to resolution until the subject is lost to follow- 
up or until the AE is otherwise classified. Resolution means the subject has returned to 
baseline state of health or the Investigator does not expect any further improvement or 
worsening of the AE. If the patient is lost to follow-up, the Investigator should make 3 
reasonable attempts to contact the patient via telephone, post, or certified mail. All follow-up 
will be documented in the subject’s source document. Non-serious AEs identified on the last 
scheduled contact must be recorded on the AE eCRF with the status noted. 
If the Investigator becomes aware of any new information regarding an existing SAE (i.e., 
resolution, change in condition, or new treatment), a new SAE/Unanticipated Report Form 

OC-01 (varenicline tartrate) Nasal Spray 
Clinical Trial Protocol #OPP-002-01EXT 
Sponsor: Oyster Point Pharma, Inc. 
January 21, 2019 
CONFIDENTIAL 
Page 20 of 32 
  
 
must be completed and faxed to 
within 24 hours of the site’s awareness of the new 
information. The original SAE form is not to be altered. The report should describe whether 
the event has resolved or continues and how the event was treated. 
8.6 
Compliance with Protocol 
Subjects will be instructed on the necessity to attend Visit 1 and Visit 2 to be examined and 
to have their adverse event information collected. 
 
8.7 
Subject Disposition 
8.7.1 
Completed Subjects 
A completed subject is one who has completed both study visits (Visit 1 and Visit 2). 
8.7.2 
Discontinued Subjects 
Subjects may be discontinued from involvement in the study at any time prior to their 
completion of the study due to: 
x AEs; 
x protocol violations; 
x sponsor termination of study; 
x non-compliance 
x withdraw by subject 
x other 
Note: In addition, any subject may be discontinued from from study involvement 
from any sound medical reason at the discretion of the investigator (after consultation 
with the Sponsor) or Sponsor. 
Notification of a subject discontinuation and the reason for discontinuation will be made to 
 Sponsor and will be clearly documented on the eCRF. 
Discontinued subjects will not be replaced.  
 
8.8 
Study Termination 
The study may be stopped at any time by the Investigator 
after consultation with 
the Sponsor, with appropriate notification. 
 
8.9 
Study Duration 
An individual subject’s participation will involve 2 study visits over approximately 6 
months 
 
8.10 Monitoring and Quality Assurance 
During the course of the study a monitor, or designee, will make routine site visits to review

For safety endpoints, both eyes will be analyzed. 
 
10 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. 
 
10.1 Protection of Human Subjects 
10.1.1  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 
 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. 
10.1.2 Institutional Review Board Approval 
This study is to be conducted in accordance with IRB regulations [U.S. 21 Code of Federal 
regulations (CFR) Part 56.103]. The investigator must obtain appropriate IRB approval 
before initiating the study and re-approval at least annually. 
Only an IRB-approved version of the informed consent form will be used. 
 
10.2 Ethical Conduct of Study 
This study will be conducted in accordance with the ethical principles that originated with the 
Declaration of Helsinki. 
 
10.3 Subject Confidentiality 
All personal study subject data collected and processed for the purposes of this study should 
be maintained by the investigator and his/her staff with adequate precautions as to ensure that 
the confidentiality of the data in accordance with local, state, and federal laws and 
regulations. 
Monitors, auditors and other authorized representatives of 
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. 
 
10.4 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. 
10.4.1  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

Sponsor to inform the investigator/institution as to when these documents no longer need to 
be retained. 
If the responsible investigator retires, relocates, or for other reasons withdraws from the 
responsibility of keeping study records, custody must be transferred to a person who will 
accept the responsibility. The Sponsor must be notified in writing of the name and address of 
the new custodian. 
 
10.5 Recording of Data on Source Documents and Electronic Case Report 
Forms 
All subject data will be captured in the subject source documents which will be transcribed in 
the eCRFs. The investigator is responsible for ensuring that study data is completely and 
accurately recorded on each subject’s eCRF, source documents, and all study-related 
materials. All study data should also be attributable, legible, contemporaneous, and original. 
Recorded datum should only be corrected in a manner that does not obliterate, destroy, or 
render illegible the previous entry (e.g., by drawing a single line through the incorrect entry 
and writing the revision next to the corrected data). An individual who has corrected a data 
entry should make clear who made the correction and when, by adding to the correction 
his/her initials as well as the date of the correction. 
Data entry of all enrolled subjects will use software that conforms to 21 CFR Part 11 
requirements, and will be performed only by staff who have been trained on the system and 
have access to the system. Data will not be entered for screen failure subjects. An audit trail 
will be maintained within the electronic system to capture all changes made within the eCRF 
database. After the end of the study and database lock, electronic copies of all applicable 
subjects’ eCRFs will be provided to each Investigator Site to be maintained on file by the 
Investigator. 
 
10.6 Handling of Biological Specimens 
Not applicable. 
 
10.7 Publications 
The study will be documented in a final report, which will contain appropriate statistical 
analysis and medical overview. No individual site or Investigator may publish or present any 
results from the study until the Sponsor completes a joint, multi-center publication of the trial 
results is made by Sponsor in conjunction with various participating Investigators and 
appropriate sites contributing data and comments. Subsequently, individual Investigators 
may request to publish or present results from the trial; however, approval will be at the sole 
discretion of the Sponsor. Should the foregoing language be in conflict with the language 
addressing publication in the clinical trial agreement, the language in the Clinical Trial 
Agreement will prevail.

APPENDIX 2: EXAMINATION PROCEDURES, TESTS, EQUIPMENT, 
AND TECHNIQUES 
The following examination procedures, tests, equipment and techniques are listed in this 
Appendix: 
 
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. 
 
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). 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.
