SYNOPSIS 
 
Protocol Title: 
Effects of NOV03 on the Tear Film in Subjects with Dry Eye 
Disease 
Protocol Number: 
922 
Investigational Product: 
Perfluorohexyloctane (PFHO; MIEBO™; NOV03) 
Study Phase: 
4 
Primary Objective(s): 
Determine the effect of a single instillation of PFHO on the 
thickness and evaporation rate of the mucus-aqueous layer of 
the tear film 
Exploratory Objective(s): 
 
 
Overall Study Design: 
Structure: 
This pilot, open label, single-arm, single-center study will 
consist of 2 study visits in subjects with dry eye disease 
associated with MGD. A Screening Visit will occur to verify 
subjects are eligible to participate followed by an Assessment 
Visit to evaluate tear film parameters at baseline and over 
approx. 4 hours following a single instillation of PFHO. 
Screening Visit: At Visit 1, the subjects will complete the 
informed consent process followed by a screening visit to 
determine the presence of dry eye and associated MGD, which 
will include slit-lamp exam, visual acuity (VA), intraocular 
pressure (IOP), meibomian gland dysfunction (MGD) 
assessment, Schirmer test, tear film break up time (TFBUT), 
corneal fluorescein staining (CFS), and ocular surface disease 
index (OSDI). 
Assessment Visit: At Visit 2, a slit lamp examination and two 
baseline tear film assessments will be performed (tear film 
parameters: mucus-aqueous layer thickness (MALT); mucus- 
aqueous thinning rate (MALTR); 
 
 
 Then 1 
drop of PFHO will be instilled into both eyes (the study eye 
will be the eye with the highest corneal fluorescein staining). 
The above assessments will be repeated at multiple time 
points up to 4 hours post-instillation (time points: 5±1 min, 
15±2 min, 30±2 min, 60±5 min, 120±10 min, 240±10 min). 
Any adverse events will be recorded.

Full Analysis Set (FAS): The FAS will consist of all enrolled subjects who are instilled with study drug 
Per Protocol Set (PP Set): The PP Set will consist of FAS subjects with no protocol violations expected 
to affect the evaluability of efficacy. 
Safety Analysis 
The number and percentage of subjects with specific treatment-emergent adverse events (TEAEs) will 
be summarized for each treatment group. The number of subjects will be tabulated by MedDRA System 
Organ Class and preferred term within each system organ class. 
Primary Efficacy Analyses 
The primary comparison in this trial is CFB in MALTR and MALT following a single instillation of 
PFHO. Change from baseline (post-instillation minus baseline, average of 2 baseline readings) at each 
post instillation time point will be summarized using continuous summary statistics. 
Hypotheses 
For each primary endpoint at each post-instillation timepoint, the null hypothesis is that the mean 
change from baseline is zero. The alternative hypothesis is that the mean change from baseline is not 
zero. 
Methods 
Each primary endpoint will be summarized by post-instillation timepoint using continuous summary 
statistics for the FAS. Paired t-tests will be used to test the statistical hypotheses. Each null hypothesis 
will be rejected if the corresponding two-sided p-value is less than 0.05. 
Sample Size Calculations 
A sample size of 30 subjects will have 80% power to detect a difference in means of 0.529 times the 
standard deviation of the paired differences, using a paired t-test with a 5% two-sided significance level.

1 INTRODUCTION 
Dry eye disease (DED) is a common ocular condition with approx. 18 million currently diagnosed with the 
disease in the US, and with many more people remaining undiagnosed (Farrand, et al. 2017; MarketScope 
2020). Typical clinical signs of DED include decreased tear fluid, tear film instability, and ocular surface 
damage with associated symptoms of dryness, grittiness, burning, stinging, light sensitivity, and blurred 
vision (Bartlett, et al. 2015; Craig, et al. 2017). Previously, DED was characterized into 2 main types, 
aqueous deficient (in which lacrimal secretion is reduced) or evaporative (in which evaporation of aqueous 
from the tear film is excessive) (Bron, et al. 2017; Craig, et al. 2017). It is now recognized that DED is on 
a continuum and that the most common cause of the disease is excessive evaporation due to conditions 
such as meibomian gland dysfunction (MGD), a reduced blink rate (for example due to long-term use of 
digital displays), certain drugs, contact lens use, and some eyelid disorders (Craig, et al. 2017). The most 
common cause of evaporative DED is MGD, which is present in approx. 9 out of 10 patients with the 
disease (Lemp, et al. 2012; Rabensteiner, et al. 2018; Badian, et al. 2021). MGD results in thinning of the 
tear film lipid layer leading to excessive evaporation of the underlying aqueous layer and associated tear 
film instability, hyperosmolarity, desiccation stress, and loss of mucin-producing goblet cells, which all 
cascade into a continuing cycle of inflammation and ocular surface damage (Baudouin, et al. 2016; Craig, 
et al. 2017). 
 
Current prescription DED therapies are aimed at reducing inflammation or increasing tear secretion but are 
not directly targeted at the main root cause of DED, namely excessive evaporation. Perfluorohexyloctane 
ophthalmic solution (PFHO; trade name MIEBO™; development name NOV03) is an FDA approved, 
water-free, non-steroidal, preservative-free eye drop indicated for treatment of the signs and symptoms of 
DED. PFHO belongs to a unique class of compounds known as semifluorinated alkanes which have low 
surface tension and amphiphilic properties due to a lipophobic/aerophilic fluorinated segment and a 
lipophilic hydrocarbon segment (Meinert and Roy 2000). PFHO is thought to act as a functional 
replacement for the lipid layer by spreading rapidly over the ocular surface to form a long-lasting, anti- 
evaporative barrier (Agarwal, et al. 2018; Krosser 2018; Borchman 2022). Therefore, PFHO may prevent 
excessive evaporation of the aqueous component of the tear film in patients with evaporative DED, thus 
reducing the signs and symptoms of DED as has been consistently demonstrated in both a Phase 2 study 
and 2 Phase 3 clinical studies (Tauber, et al. 2021; Sheppard 2022; Tauber, et al. 2022). 
 
To date, the effect of PFHO on inhibiting evaporation in vivo has not been demonstrated and there is 
limited available information regarding how PFHO modulates the lipid and aqueous tear film layers; in 
addition, demonstration of inhibition of evaporation by PFHO is currently limited to in vitro data. The 
Tear Film Imager (AdOM, Advanced Optical Technologies Ltd, Lod, Israel) combines spectrometry and 
imaging to quantitatively assess changes in the tear lipid and aqueous layers with nanometer resolution. 
There are 6 tear film parameters which are measured simultaneously with the TFI: 
 
1. MALT: the average Muco-Aqueous Layer Thickness in nanometer resolution 
2. MALTR: the rate of change of the MALT value in nm/sec, as measured in the steady state phase of 
a representative blink 
3. LLT: the average Lipid Layer Thickness in nanometer resolution 
4. LBUT: the Lipid Break Up Time (in sec) which strongly correlates to tear breakup time 
5. IBI: the average Inter-Blink-Interval (in sec). 
6. LMU: the average Lipid Map Uniformity measured on the Lipid map taken about 1 second after the 
blink which allows quantitation of the spatial variation of lipid across the cornea.

Several studies have been published which evaluated tear film parameters with the TFI. Cohen et al used 
the TFI to demonstrate that the distribution of lipid in eyes with DED is nonuniform and has more variance 
over the corneal surface as compared to normal eyes and hypothesized that this nonuniformity may be the 
cause of increased evaporation of the aqueous tear film layer in DED (Cohen, et al. 2020). In addition, the 
parameters of MALT and LBUT have been shown to be significantly thinner and shorter, respectively, in 
patients with DED vs controls (Segev, et al. 2020). Data from a recent study has also demonstrated 
correlation of specific tear film parameters with certain DED symptoms and/or signs (Arita, et al. 2022). 
Lastly, unpublished pilot data suggests that PFHO may decrease the MALTR and thus the rate of 
evaporation in a subject with evaporative DED. 
 
2 STUDY OBJECTIVES 
The primary objective is to test the hypotheses (twelve) that the effects of a single instillation of PFHO in 
the study eye on the thickness and evaporation rate of the mucus-aqueous layer of the tear film at six time 
points between 5 minutes and 4-hours (5±1 min, 15±2 min, 30±2 min, 60±5 min, 120±10 min, 240±10 
min) after instillation are nominally statistically significant in adults with established currently untreated 
bilateral dry eye disease associated with meibomian gland dysfunction who are not recent users of contact 
lenses or any medication that could affect ocular dryness. 
 
 
 
 
3 CLINICAL HYPOTHESES 
It is hypothesized that PFHO will increase MALT and decrease MALTR in a population of subjects with 
dry eye disease associated with MGD. 
 
4 OVERALL STUDY DESIGN 
This is a pilot, open label, single arm study. 
The study will consist of 2 study visits: a Screening Visit to verify subjects are eligible to participate and an 
Assessment study visit to evaluate tear film parameters at baseline and over approx. 4 hours following a 
single instillation of PFHO (Figure 1). 
At Visit 1, the subjects will complete the informed consent process followed by a screening visit to determine 
the presence of dry eye and associated MGD, which will include slit-lamp exam, visual acuity (VA), IOP, 
MGD assessment, Schirmer test, TBUT, CFS, OSDI. At Visit 2, a slit lamp examination will be performed. 
After 20 min, a baseline examination will be conducted by performing a Tear Film Imager assessment in the 
study eye (tear film parameters measured twice 20-40 min apart; study eye = worst CFS eye at baseline). 
The study eye drop will then be applied to both eyes. Tear film imager assessments will then be performed 
in the study eye at multiple time points up to 4 hours post-instillation as shown in Figure 1.

9 ADVERSE EVENTS 
 
Definition of Adverse Event (AE) 
An adverse event is any untoward medical occurrence in a subject participating in a clinical study, which 
does not necessarily have a causal relationship with the study product/procedure. Therefore, an adverse 
event includes: 
• Any unfavorable and/or unintended sign (including an abnormal laboratory finding), symptom, or 
disease onset, that occurs at any time between the signing of the ICF and study exit, without any 
judgement about causality (i.e., whether or not it is considered to be related to the study product) 
• Exacerbation, worsening, or progression of a pre-existing illness, including an increase in severity, 
frequency, and/or duration of a pre-existing episodic event or condition 
• Events occurring from drug overdose (accidental or intentional), drug abuse or misuse, drug 
hypersensitivity, drug extravasation, drug interactions, drug dependency, events occurring from 
drug withdrawal and medication errors 
• A condition detected or diagnosed after study product administration even though it may have been 
present prior to the start of the study 
A treatment-emergent adverse event (TEAE) is defined as an AE with a start date on or after the first dose 
of study drug, or that worsened following administration of study drug. 
An AE does not include the following: 

NOV03 (Perfluorohexyloctane) 
Clinical Trial Protocol #922 
Sponsor: Bausch & Lomb Incorporated 
Oct 16th 2023 FINAL v3.0 
Confidential 
Page 25 of 47 
 
 
• Medical or surgical procedures (e.g., surgery, endoscopy, tooth extraction, transfusion) as event 
terms; the condition that led to the procedure is the AE if it meets the definition of an AE. 
•  Situations where an untoward medical occurrence has not occurred (e.g., hospitalization for 
cosmetic elective surgery; and social and/or convenience admissions). 
Symptoms associated with disease, which are consistent with the subject’s usual clinical course; unless the 
subject experiences worsening of their symptom(s) or the symptom(s) meet the criteria for an SAE. 
 
9.1.1 Assessment of Severity of Adverse Events 
The severity of an AE will be graded as follows: 
Mild 
Awareness of a sign or symptom but is easily tolerated, 
requires no treatment, and does not interfere with subject’s 
daily activities 
Moderate 
Low level of concern to the subject and may interfere with 
daily activities but can be relieved by simple therapeutic 
care. 
Severe 
Interrupts the subject’s daily activity and requires 
systemic therapy or other treatment 
 
9.1.2 Assessment of Causality of Adverse Events 
The relationship of an AE to the study product will be assessed using the following guidelines, based upon 
available information: 
 
Related 
There is at least a reasonable possibility that the AE/SAE 
is related to the study drug. Reasonable possibility means 
that there is evidence to suggest a causal relationship 
between the drug and the AE. 
Not Related 
There is little or no reasonable possibility that the 
AE/SAE is related to the study drug. This assessment 
implies that the AE/SAE has little or no temporal 
relationship to the study drug and/or a more likely or 
certain alternative etiology exists. 
 
Rationale MUST be provided for any “not related” assessment and is recommended for “related” 
assessments. 
 
Serious Adverse Events 
An AE is considered “serious” if it meets at least one of the following criteria. The event: 
• Results in death 

NOV03 (Perfluorohexyloctane) 
Clinical Trial Protocol #922 
Sponsor: Bausch & Lomb Incorporated 
Oct 16th 2023 FINAL v3.0 
Confidential 
Page 26 of 47 
 
 
• Is life threatening (places the subject at immediate risk of death) 
NOTE: The term “life-threatening” in the definition of “serious” refers to an event in which the subject 
was at risk of death at the time of the event. It does not refer to an event which hypothetically might have 
caused death if it were more severe. 
• Requires inpatient hospitalization or prolongation of existing hospitalization NOTE: The term 
“hospitalization” refers to admission to a hospital as an in-patient for more than 24 hours. 
Therefore, an adverse event would meet the SAE criterion of “requires hospitalization” only if the 
event necessitated admission to a health care facility for longer than 24 hours. Elective 
hospitalization for an intervention that was already planned before inclusion of the subject in the 
study, hospitalization solely for the purpose of diagnostic tests (even if related to an AE), hospital 
admission for social circumstances, and admission to a day-care facility may not constitute 
sufficient grounds to be considered an SAE. 
Cases in which subjects are retained in the emergency room for more than 24 hours but not 
admitted for medical care should be evaluated individually, because the criterion “otherwise 
medically significant” may apply (see below). 
• Results in persistent or significant disability/incapacity 
NOTE: The term “disability” means a substantial disruption of a person’s ability to conduct normal 
life functions. This definition is not intended to include experiences of relatively minor medical 
significance (e.g., uncomplicated headache, influenza, or sprained ankle) that may transiently 
interfere with or prevent everyday life functions but do not constitute a substantial disruption. 
• Is a congenital anomaly/birth defect 
• Is considered otherwise medically significant, as determined by the PI or medically qualified sub- 
investigator 
NOTE: The term “medically significant” refers to important medical events that may not immediately 
be life threatening or result in death or hospitalization, but, based upon appropriate medical judgment, 
they jeopardize the subject or require medical or surgical intervention to prevent one of the other 
outcomes listed in the definition of an SAE. 
Examples of such medically significant events include allergic bronchospasm requiring intensive 
treatment in an emergency room or at home, blood dyscrasias, convulsions that do not result in 
inpatient hospitalization, or the development of drug dependency or drug abuse. 
Spontaneous abortion, elective abortion and ectopic pregnancy will be considered SAEs and must be reported 
to the sponsor within 24 hours of awareness of the event. 
Subjects will be withdrawn from the study if an SAE is identified and thought to be related to the study drug. 
The investigator is responsible for the reporting of all SAEs. 
Within 24 hours following the investigator’s knowledge of an SAE, the investigator must: 
• Report the SAE to the sponsor/designee. 
All SAEs occurring between screening and 30 days after the last administered dose of study drug 
(inclusive) must be reported to the sponsor/designee, independent of the circumstance or suspected 
cause, and regardless of the relationship to the study drug or protocol, within 24 hours from the time 
the event was reported to the investigator. For events occurring beyond the 30-day period after the 
last application of study drug, or for any timeframe greater than 30 days deemed medically

significant, only SAEs considered related to the study drug should be reported promptly to the 
sponsor. 
If the subject dies during participation in the study or during recognized follow-up period, and if 
cause of death is not available within the 24-hour reporting period, “death” must be reported as an 
SAE term to meet the timelines. Cause of death must be actively queried and submitted as a follow- 
up report.

Include copies of all confirmatory examinations carried out and the dates on which these 
examinations were performed. Care should be taken to ensure that the subject's identity is protected 
(personal identifiers are redacted), and the date and subject identifier in the clinical trial (i.e., 
subject number) are clearly visible on every page/copy of source document provided to the sponsor. 
For laboratory results, include the laboratory normal ranges. 
• Investigators should not wait to receive additional information before notifying the sponsor of an 
SAE. If only limited information is initially available, follow-up reports are required. 
Within 48 hours following the investigator’s knowledge of an SAE, the investigator must: 
• Enter the information related to the SAE in the appropriate sections of the CRF. 
• Send notification of the SAE to the monitoring team after investigator approval of the CRF 
All further data updates should be recorded in the CRF within one working day of knowledge of this 
additional information. Send notification of the updated SAE information to the monitoring team after 
investigator approval of the CRF. 
Additional documentation (e.g., laboratory data, concomitant medication, subject status, etc.), should 
be sent by fax or e-mail to the monitoring team within one working day of knowledge of this 
information. Care should be taken to ensure that the subject's identity is protected (personal identifiers 
are redacted) and the date and subject identifier in the clinical trial (i.e., subject number) are clearly 
visible on every page/copy of source document that is provided to the monitoring team. For laboratory 
results, include the laboratory normal ranges. 
After the EOS visit, the investigator does not need to actively monitor subjects for new SAEs. 
However, if the investigator becomes aware of a new or previously unreported serious adverse event 
within 30 days after the last investigational drug instillation, the event should be reported to the 
sponsor/designee within 24 hours of learning of the event. If the investigator becomes aware of a new 
or previously unreported SAE after 30 days from the last investigational drug instillation, only SAEs 
considered related to the study drug should be reported to the sponsor within 24 hours of the 
investigator’s knowledge of the event. Serious adverse events reported outside of the protocol-required 
reporting period will be captured within the safety database as clinical trial SAE Report Form cases for 
the purposes of expedited reporting.

9.2.1 Expedited Serious Adverse Events 
Any suspected unexpected serious adverse event considered related to the study drug may warrant 
expedited reporting. In addition, any unexpected SAE related to a subject’s participation in the study (or 
related to the conduct of the study), regardless of whether or not the study drug was administered, will be 
evaluated by Global Pharmacovigilance and Risk Management to determine if expedited reporting is 
required. For example, an unexpected, severe SAE that could be associated with the study procedures and 
could modify the study conduct requires expedited reporting. 
Each expedited safety report will routinely include a brief cover memorandum, the completed MedWatch 
Form FDA 3500A, a clinical analysis of the event with any similar events that have occurred with the 
product, and any additional pertinent information recommended by the study medical monitor. Once the 
report is compiled, the study center’s investigator must submit the expedited safety report to the local 
IRB/IEC within the required reporting timeframe. Follow-up reports should be submitted when requested 
or when pertinent information becomes available. The principal investigator must retain a complete copy of 
each expedited safety report as it was submitted to the IRB/IEC. It is important that the principal 
investigator review these expedited reports, as they contain safety information that may be relevant to each 
of the participating subjects. 
 
9.2.2 Pregnancy 
All female subjects of childbearing potential and male subjects with female partners of childbearing 
potential must use an effective method of birth control during the course of the study, in a manner such that 
risk of contraceptive failure is minimized. Abstinence is allowed as a birth control method. Before 
enrolling a female subject of childbearing potential or a male subject with a female partner of childbearing 
potential, the investigator must review the following information about study participation: 
 
• Informed consent requirement 
• Contraceptives in current use 
By signing the informed consent form, the investigator or designee asserts that he/she has discussed this 
information with the subject and provided appropriate counseling. Following the review of this 
information, the subject must sign the informed consent form to enroll in the study. During the study, all 
subjects should be instructed to contact the investigator immediately if they suspect that they or their 
partners might be pregnant (e.g., missed or late menstrual period). 
 
If a subject or investigator suspects that the subject may be pregnant prior to treatment, the study drug must 
be withheld until the results of laboratory pregnancy testing are available. If pregnancy is confirmed, the 
subject is considered to be a screen failure, must not continue in the study, and must not receive study drug. 
If pregnancy is suspected while the subject is receiving study treatment, the study drug must immediately 
be withheld until the result of pregnancy testing is known. If pregnancy is confirmed, the study drug will 
be permanently discontinued, and the subject and neonate will be followed until 30 days after the 
pregnancy comes to term. A Pregnancy Report form will be submitted to the sponsor, both when 
pregnancy is confirmed, and 30 days after the delivery date. Information provided on the Pregnancy 
Report Form must include the outcome of the pregnancy and any complications occurring during the 
pregnancy or the delivery. 
 
If a subject is withdrawn from the study and is found to be pregnant within 30 days of withdrawal, the 
subject and neonate will be followed until 30 days after the pregnancy comes to term.

All confirmed pregnancies must be immediately reported to the sponsor/designee and medical monitor on a 
Pregnancy Report form within 24 hours of the investigator’s awareness of the pregnancy. If a pregnancy is 
associated with an SAE, an SAE report form should also be submitted to the sponsor/designee and medical 
monitor within 24 hours of the investigator’s awareness. Abnormal pregnancy outcomes (e.g., spontaneous 
abortion, fetal death, stillbirth, congenital anomalies, ectopic pregnancy) are considered SAEs. 
 
Completed SAE Report Forms and completed Pregnancy Report Forms should be transmitted to the 
sponsor/designee and the medical monitor using the contact information provided in Section 9.2 above. 
 
If/when the investigator becomes aware of any new information regarding a pregnancy, the 
sponsor/designee and medical monitor should be notified of these updates as soon as the new information 
becomes available. Updates should be documented on a Pregnancy Report Form and sent by fax or email 
using the contact information provided above. The report should be marked as a follow-up report” and 
should include the updated status of the pregnancy. The original Pregnancy Report Form is not to be 
altered. 
 
 
General Guidelines for Reporting Adverse Events 
It is the responsibility of the investigator to document all AEs that occur during the course of the study. 
Throughout the study, efforts will be made by the investigator to remain alert to possible AEs. The period 
of observation for collection of AEs extends from the time the subject gives informed consent until the last 
study visit or discontinuation from the study. The first concern will always be the safety of the subject, and 
appropriate medical intervention will be made. 
The AEs should be documented as a single medical diagnosis. When this is not possible, the AE should be 
documented in terms of signs and/or symptoms observed by the investigator or reported by the subject at 
each study visit. Each AE which appears to be independent of any prior event will be reported separately. 
All AEs occurring after the subject signs the informed consent through the last study visit must be reported, 
regardless of whether or not the AEs are considered drug-related. All AEs, whether in response to a query, 
observed by the study site personnel, or reported spontaneously by the subject, will be recorded. Any AEs 
deemed related to treatment reported or observed at the final study/treatment visit will be followed until 
stabilization or resolution (or up to 30 days after final study visit). 
At each visit during the study, the subject will be assessed for the occurrence of new and ongoing AEs. 
Tolerability signs and symptoms that result in the subject’s requiring a concomitant therapy, interruption of 
treatment, or discontinuation from the study will be reported as an AE. The following data will be collected 
on all AEs and recorded on the appropriate CRF: 
• Event name (diagnosis preferred, if unknown, record the signs/symptoms) 
• Onset date and end date 
• Maximum intensity (severity) 
• Seriousness 
• Action taken regarding study drug 
• Corrective treatment/therapy, if given 
• Outcome

• Resolution 
The investigator will also provide an assessment of the causal relationship to the study drug (for pre- 
treatment AEs, causality is “not related”). Rationale MUST be provided for any “not related” assessment 
and is recommended for “related” assessments. 
All AEs must be reported regardless of whether the AEs are considered drug-related. 
In order to ensure the safety of the subjects, the investigator should take appropriate measures to follow all 
subjects with adverse events until clinical recovery is complete, progression has been stabilized, the subject 
is lost to follow-up, or until death. This may result in the need for observations to continue beyond the last 
planned protocol specified visit, and additional investigations may be requested by the monitoring team. 
If a subject requires further follow-up of ongoing AEs upon discontinuation or completion of the study, the 
Investigator should schedule post-study follow-up visits, as necessary. 
Laboratory results, vital signs, or ECG abnormalities are to be recorded as AEs (or SAEs, if applicable) 
only if at least one of the following apply: 
• the result is clinically significant 
• the subject is symptomatic 
• the subject requires either corrective treatment or consultation 
• the lab result, vital sign, or ECG abnormality leads to study drug discontinuation or dose 
modification 
• the event fulfills a criterion for an SAE 
In addition, the investigator’s assessment of causality will be recorded. 
Vital sign abnormalities are to be recorded as AEs (or SAEs, if applicable) only if they are clinically 
significant (for example: are symptomatic, requiring corrective treatment, leading to discontinuation or 
fulfilling a seriousness criterion). 
 
10 STATISTICS 
 
Assessment of Efficacy 
Efficacy evaluations will be completed using the Full Analysis Set. 
10.1.1 Primary Efficacy 
For each primary endpoint at each post-instillation timepoint, the null hypothesis (H0) is that the mean 
change from baseline (δ) is zero. The alternative hypothesis is that the mean change from baseline is not 
zero. 
𝐻𝐻0: 𝛿𝛿 = 0 
𝐻𝐻1: 𝛿𝛿 ≠ 0 
MALT and MALTR will be summarized using continuous summary statistics by time point (baseline, 5 
minutes, 15 minutes, 30 minutes, 1-, 2-, and 4 hours). Change from baseline (post-instillation minus 
baseline) at each post instillation time point will be summarized using continuous summary statistics. 
Paired t-tests will be used to test the statistical hypotheses.

10.1.2 Secondary Efficacy 
This section is not applicable because there are no secondary efficacy endpoints. 
10.1.3 Exploratory Efficacy 
The exploratory endpoints will be analyzed in the same manner as the primary efficacy endpoints. 
10.1.4 Statistical Hypothesis Testing and Control of Multiplicity 
Due to clinical considerations, the 36 statistical tests will not be adjusted for multiplicity. The p-values and 
any conclusions of statistical significance will be considered nominal. 
10.1.5 General Considerations 
Quantitative variables will be summarized descriptively using the number of subjects (n), mean, median, 
standard deviation, minimum, and maximum. Qualitative variables will be summarized using counts and 
percentages. 
All efficacy analyses will use a two-sided alpha = 0.05 test unless otherwise stated and corresponding 2- 
sided 95% confidence intervals (CIs) will be presented as applicable. 
For efficacy and non-ocular safety analyses, the unit of analysis will be the subject. In the cases where 
assessments are recorded for each eye, the study eye and fellow eye will be summarized separately and a 
mean across all eyes will also be calculated. 
 
Adverse events will also be summarized at the subject level; if an AE occurs in either or both eyes, the 
subject will be counted as having the AE. For other ocular safety analyses the unit of analysis will be the 
eye, with summaries showing results for the study eye and the fellow eye separately. 
 
 
Assessment of Safety 
The following safety variables will be recorded: 
 
• Adverse Events (AEs; reported, elicited and observed) 
10.2.1 Adverse Events 
Adverse events (AEs) will be coded using the MedDRA dictionary. Frequencies and percentages of 
treatment-emergent adverse events (TEAEs) will be summarized at the subject level by system organ class 
and preferred term for all TEAEs, treatment related TEAEs, and serious TEAEs. An AE is treatment 
emergent if it occurs or worsens after the first dose of study medication. Similar summaries will be 
presented for all TEAEs by maximal severity. Separate summaries will be performed for ocular and non- 
ocular AEs. 
10.2.2 Concomitant Medications 
All previous concomitant medications will be classified based on terminology from the WHO Drug 
Dictionary. Previous therapies and concomitant medications data will be presented in data listings. 
 
 
Subject Disposition 
Subject disposition will be presented in terms of the numbers and percentages of subjects who completed 
the study and discontinued from the study.

The number and percentage of subjects who prematurely discontinue from the study and the reasons for 
study discontinuation will be summarized. 
 
 
Demographics and Baseline Characteristics 
Subject demographics including age, sex, ethnicity, race, and baseline characteristics will be summarized 
using the appropriate descriptive statistics. 
 
Protocol Deviations 
All protocol deviations will be reported to the sponsor and recorded throughout the study. A tabulation of 
protocol deviations (including categorizations of major and minor) will be presented. 
Important protocol deviations leading to exclusion from the Per-Protocol Population will include the 
following. 
• Ineligibility 
• Missing primary endpoint data at any time point at Visit 1 
• Use of any prohibited medication potentially affecting the primary endpoint at Visit 1 
 
 
 
Compliance 
Compliance will not be evaluated in this study since the site will administer the drop. 
 
 
Interim Analyses 
There are no interim analyses planned for this study. 
 
 
Additional Statistical Considerations 
10.8.1 Analysis Population 
• Full Analysis Set (FAS): The FAS will consist of all subjects who are instilled with study 
drug. 
• Per Protocol Set (PP Set): The PP Set will consist of FAS subjects with no protocol 
deviations expected to affect the evaluability of efficacy. 
10.8.2 Sample Size Determination 
A sample size of 30 subjects will have 80% power to detect a difference in means of 0.529 times the standard 
deviation of the paired differences, using a paired t-test with a 5% two-sided significance level. 
10.8.3 Multiplicity Issues 
The probability of at least one type 1 error will be approximately 79% under the universal null hypothesis 
if the 36 endpoints are independent.

11 COMPLIANCE WITH GOOD CLINICAL PRACTICES, ETHICAL 
CONSIDERATIONS, AND ADMINISTRATIVE ISSUES 
This study will be conducted in compliance with the protocol, current Good Clinical Practices (GCPs), 
including the International Conference on Harmonisation (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 IP in the countries involved will be adhered to. 
 
 
Protection of Human Subjects 
11.1.1 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/IEC 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 B+L prior to submission to the governing 
IRB/IEC 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. 
11.1.2 Institutional Review Board (IRB) Approval 
This study is to be conducted in accordance with IRB regulations (U.S. 21 CFR Part 56.103). The 
investigator must obtain appropriate IRB approval before initiating the study and re-approval at least 
annually. 
Only an IRB/IEC approved version of the informed consent form will be used. 
 
 
Ethical Conduct of the Study 
This study will be conducted in accordance with the ethical principles that originated with the Declaration 
of Helsinki. 
 
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 is in accordance with local, state, and federal laws and regulations. 
Anonymized TFI measurement data will be analyzed by AdOM. 
Monitors, auditors and other authorized representatives of the sponsor, the IRB/IEC approving this study, 
the FDA, the DHHS, other domestic government agencies, and other foreign regulatory agencies will be 
granted direct access to the 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 IP may ultimately be marketed, but the subject’s identity will not be disclosed in these 
documents. 
 
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 EKGs. The 
investigator’s copy of the CRFs serves as the investigator’s record of a subject’s study-related data. 
11.4.1 Retention of Documentation 
All study related correspondence, subject records, consent forms, record of the distribution and use of all 
IP, 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 IP. 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. 
 
 Labeling, Packaging, Storage, Accountability, and Return or Disposal of 
Investigational Product 
11.5.1 Labeling/Packaging 
The investigational materials will be packaged and labeled in a manner consistent with the study design. 
They will be labelled according to the local regulatory requirements 
11.5.2 Storage of Investigational Product 
The IP must be stored in a secure area accessible only to the investigator and his/her designees. The IP will 
be administered only to subjects entered into the clinical study, in accordance with the conditions specified 
in this protocol. 
11.5.3 Accountability of Investigational Product 
The IP is to only be prescribed by the principal investigator or his/her named sub-investigator(s), and is to 
only be used in accordance with this protocol. The IP must only be distributed to subjects properly 
qualified under this protocol to receive IP. 
The investigator must keep an accurate accounting of the IP received from the sponsor on the Product 
Accountability Log. 
11.5.4 Return or Disposal of Investigational Product
