SYNOPSIS 
Study Title:
Safety and Efficacy of KPI-121 1% Ophthalmic Suspension versus 
Prednisolone Acetate Ophthalmic Suspension 1% for the Treatment 
of Inflammation Following Cataract Surgery in Children 0 to 3 
Years of Age
Objectives:
To compare the safety and efficacy of KPI-121 1% ophthalmic
suspension (KPI-121 1%) dosed twice daily versus prednisolone
acetate ophthalmic suspension 1% (prednisolone acetate 1%) dosed
four times daily in children 0 to 3 years of age following cataract
surgery.
Study Population: 
The study population will consist of pediatric subjects from 0 
through 3 years of age who have undergone routine, uncomplicated 
cataract surgery.
Number of 
Subjects:
Approximately 120 subjects who are candidates for cataract surgery 
will be screened. One study eye from approximately 60 subjects
will be randomized.
Investigational 
Products:
KPI-121 1% and vehicle or prednisolone acetate 1% will be 
supplied as investigational product.
Route and Duration 
of Administration:
Subjects will be randomized to either:
x
1-2 drops of KPI-121 1% and vehicle dosed two times per day
each for a total of four times per day (QID) instilled in the 
study eye for 29 days ± 2 days post-surgery, starting at the first 
post-operative assessment. This may be followed by treatment 
or taper using a commercially available product as determined 
by the Investigator.
OR
x
1-2 drops of prednisolone acetate 1% dosed QID instilled in 
the study eye for 29 days ± 2 days post-surgery, at the first 
post-operative assessment. This may be followed by treatment 
or taper using a commercially available product as determined 
by the Investigator.
Study Design:  
This is a Phase 3B, multicenter, double-masked, randomized, 
parallel-group, active-controlled study designed to evaluate the 
safety and efficacy of KPI-121 1% versus prednisolone acetate 1%
in controlling postoperative inflammation in children 0 to 3 years of 
age who have undergone cataract surgery. Approximately 120 
subjects who are candidates for cataract surgery will be screened.

Subjects who meet all eligibility criteria and undergo routine, 
uncomplicated, cataract surgery will be randomized into this study 
at approximately 20 centers located in the United States (US). 
Subjects will be randomized into one of two study groups in an 
approximate 1:1 ratio. Subjects will be randomized to either:
o
BOTH KPI-121 1% ophthalmic suspension AND
KPI-121 vehicle dosed BID each for 29 days ± 2
OR
o
Prednisolone acetate ophthalmic suspension 1% 
dosed QID for 29 days ± 2 days.  
Dosing with investigational product will be initiated at the first 
post-operative assessment and will be instilled as one to two drops
in the surgery eye according to the assigned dosing regimen for 29
± 2 days. This may be followed by treatment or taper using a 
commercially available product as determined by the Investigator.
This study will include 6 clinic visits as well as the surgery visit
over 35 to 53 days total study duration. Visit 1 (Screening) will 
occur between 14 and 1 day(s) prior to surgery. Subjects who meet
preoperative screening inclusion/exclusion criteria will be entered 
into the study. On the day of surgery, subjects will undergo routine 
cataract surgery according to the Investigator’s normal procedures.
At the first post-surgery assessment, which may be later on the
same day of surgery or the following day, eligibility regarding 
inclusion and exclusion criteria will be confirmed and subjects will 
be randomized to one of the two treatment arms. The first dose of 
investigational product will be administered in the clinic, and
parents/guardians will be instructed how to dose and record 
investigational product use. This will be considered Day 1 (Visit 2).
Following randomization, subjects’ parents/caregivers will be 
instructed to return to the clinic to be evaluated on Day 8 ± 2 days
(Visit 3), Day 15 ± 2 days (Visit 4), Day 29 ± 2 days (Visit 5), and 
Day 36 ± 2 days (Visit 6). Additional investigational product will 
be dispensed at Visit 4. Investigational product will be discontinued 
at Visit 5. Used investigational product kits will be collected by the 
study staff at Visits 4 and 5. At Visit 5 further treatment or taper
with a commercially available product may be given as determined 
by the Investigator. Additionally, a phone contact will be made 
between Visits 4 and 5 (Day 21-23) to assess subject progress.
Subjects will return for a Follow-Up/Safety Visit on Day 36 ± 2
days (Visit 6).

Efficacy 
Evaluation:
Primary Efficacy Evaluation:
1. The proportion of study eyes with anterior chamber cell
grade = 0 at Visit 4 (Day 15 ± 2 days) without receiving rescue 
medication prior to Visit 4 as compared between the KPI-121
1% dose BID and the prednisolone acetate 1% dosed QID 
treatment arms.
Secondary Efficacy Evaluation:
1. The proportion of study eyes with a Modified Global Overall 
Assessment of Postoperative Inflammation Score = 0 at Visit 4
(Day 15 ± 2 days) without receiving rescue medication prior to 
Visit 4 as compared between the KPI-121 1% BID and the 
prednisolone acetate 1% QID treatment arms.
Statistical Analysis:
The efficacy and safety analyses will be based on a single study eye 
for each subject.  Each subject’s study eye will be defined as the 
surgery eye. All statistical analyses will be performed using 
Statistical Analysis System (SAS) software.

The primary analysis population will be the Intent-to-Treat (ITT) 
population, defined as all subjects randomized and with at least one 
post-baseline assessment. A subset of efficacy analyses, the Per 
Protocol (PP) population, will be repeated using data from those 
subjects who were randomized, completed 15 days ± 2 days of 
investigational product use, had complete data at Visit 4 (Day 15 ± 
2 days), and did not have significant protocol deviations. Rescued 
subjects will be included in the PP population if they did not have
significant protocol deviations: however, these subjects will be 
considered treatment failures.
No inferential statistical analyses are planned. Data will be 
summarized using descriptive statistics only. Assessment of 
efficacy will be based primarily on the number and percentage of 
subjects in each treatment group with an anterior chamber cell grade 
of 0 at Visit 4 (Day 15 ± 2 days) with no need for rescue medication 
through Visit 4 and, secondarily, on the Modified Global Overall 
Assessment of Postoperative Inflammation score of 0 at Visit 4
(Day 15 ± 2 days) without receiving rescue medication prior to Visit 
4.
The individual components of the Global Assessment score will 
also be evaluated (i.e., number and percentage of subjects in each 
treatment group in each score category at each visit). 
Safety Evaluations:
Assessment of AEs
Change from baseline to each post-surgery visit in ocular signs:
x
Visual Acuity
x
IOP Measurement
x
Dilated Ophthalmoscopy (at Visits 1 and 5 only)
Assessment of safety will be based on the assessment of AEs. To 
allow for at least a 95% chance of detecting an AE with a 10% 
incidence rate, a minimum sample size of 30 subjects per group 
(KPI-121 1% or prednisolone acetate 1%) is required.
Eligibility Criteria:
Inclusion Criteria:
At Visit 1, individuals of either gender and any race will be eligible

INTRODUCTION
The most frequent surgery in ophthalmology is cataract extraction and intraocular lens
(IOL) implantation in adult patients with age-related cataracts. Most controlled clinical
trials evaluating the anti-inflammatoryactivity of topical corticosteroids have been
conducted in this patient population and have demonstrated efficacy in the treatment of 
both inflammation and pain following cataract surgery.
Children also experience cataracts, which are often treated via surgery, although the
incidence is significantly less than in adults. Pediatric cataract is a major cause of 
preventable childhood blindness, affecting approximately 200,000 children worldwide,
with an estimated prevalence ranging from three to six per 10,000 live births (Foster, 
Gilbert, & Rahi, 1997; Holmes, Leske, Burke, & Hodge, 2003; Stayte, Reeves, &
Wortham, 1993).  Pediatric cataracts are characterized as congenital if present within the
first year of life, developmental if present after infancy, or traumatic if caused by injury.
As in adults, the most common treatment for cataract in the pediatric population is
cataract extraction. Pediatric cataract surgery has historically been associated with a
high incidence of postoperative inflammation, which is most commonly treated with
topical corticosteroids (Sharma, Pushker, Dada, Vajpayee, & Dada, 1999; Zwaan,
Mullaney, Awad, Al-Mesfer, & Wheeler, 1998). Although improvements in surgical
techniques and IOL design have improved outcomes in pediatric cataract surgery, 
postoperative inflammation is still a concern for these patients (Medsinge & Nischal,
2015). Topical corticosteroids are generally considered to have significant anti-
inflammatory activity in pediatric patients, despite a dearth of controlled studies in this
population. In the American Academy of Ophthalmology Pediatric Ophthalmology
Education Center’s publication ‘Pediatric Cataracts: Overview’ the following is stated: 
“Prednisolone eye drops are the mainstay of treatment to control severe inflammation,
which is generally inevitable” (Wilson, 2016).

developing this novel loteprednol etabonate formulation for the treatment of 
postoperative anterior segment inflammation and pain.
KPI-121 vehicle has the same excipient composition as KPI-121 1% ophthalmic 
suspension with the exception of the active drug, LE.
Pred Forte® (prednisolone acetate ophthalmic suspension, USP) 1%, an approved
glucocorticoid product, will be purchased and supplied to sites as the active comparator
product. Pred Forte® contains prednisolone acetate (microfine suspension) 1% as the 
active ingredient. Inactive ingredients are benzalkonium chloride (as preservative); boric 
acid; edetate disodium; hypromellose; polysorbate 80; purified water; sodium bisulfite; 
sodium chloride; and sodium citrate. The pH during its shelf life ranges from 5.0 - 6.0.
For additional details on toxicology studies and the respective safety profiles, see the 
KPI-121 Investigator’s Brochure and the Pred Forte® package insert.
1.2.
JUSTIFICATION FOR ROUTE OF ADMINISTRATION AND DOSE SELECTION
KPI-121 1% and prednisolone acetate 1% will be administered as topical ophthalmic 
suspensions. Direct instillation into the eye is the most efficient method for delivery to 
the ocular surface and is an accepted and widely used method for topical application to 
the eye. KPI-121 1% dosed BID has been shown to be safe and effective in adults (Kim, 
Gupta, Holland and Brazzell, 2018). Prednisolone acetate 1% dosed QID has been shown 
to be safe and effective in both adults and children (Wilson, 2016).
1.3.
GCP COMPLIANCE
This clinical trial will be conducted in compliance with the protocol, International 
Conference on Harmonization (ICH) guidelines, Good Clinical Practices (GCP) 
guidelines and other applicable regulatory requirements.
1.4.
POPULATION TO BE STUDIED
Approximately 120 subjects, from 0 - 3 years of age, who are candidates for cataract 
surgery will be screened. The surgical/study eye from approximately 60 subjects who 
have undergone routine, uncomplicated, cataract surgery, with or without capsulotomy 
and vitrectomy and with or without posterior chamber intraocular lens (IOL) 
implantation, but not combined with any other surgery, will be randomized and evaluated 
at approximately 20 centers located in the US.

Dosing of investigational product will be initiated at the first post-surgery assessment, 
Visit 2 (Day 1), instilled as 1-2 drops in the study eye. The first dose of investigational 
product will be administered by the subject’s parent/caregiver under the supervision of a 
dedicated dosing coordinator who is otherwise uninvolved in the assessment or 
evaluation of the subject.
This study will include up to 6 clinic study visits and a phone contact and 35 to 53 days
total study duration. Visit 1 (Screening) will occur between 14 and 1 day(s) prior to 
surgery and subjects who meet preoperative screening inclusion/exclusion criteria will be 
entered into the study. On the day of Surgery, subjects will undergo routine cataract 
surgery according to the Investigator’s normal procedures. The first post-surgery
assessment, which may be later on the same day of surgery or the following day will be 
considered Visit 2 (Day 1). At this visit, subjects who continue to meet the eligibility 
criteria will be randomized to one of the two study groups and will initiate dosing with 
investigational product. Following randomization, the subject’s parent/caregiver will be 
instructed to instill investigational product in the study eye four times a day (QID) for 29
days ± 2 days up until Visit 5. The subject will return to the clinic to be evaluated at Visit 
3 (Day 8 ± 2 days), Visit 4 (Day 15 ± 2 days) and Visit 5 (Day 29 ± 2 days/End of 
Investigational Product Use Visit). A phone contact will be made between Visits 4 and 5 
(Day 21 -23) to assess subject progress.
Investigational product will be discontinued and collected at Visit 5. This may be 
followed by treatment or taper using a commercially available product as determined by 
the Investigator. Subjects will return for a follow up visit, Visit 6 (Day 36 ± 2 days) then

white, high impact polystyrene caps. The commercial bottle label will be over-wrapped to 
cover the commercial label, and then a masked clinical trial label will be applied to the 
overwrap. masked clinical trial label. 
Subjects’ parents/caregivers will be instructed to shake the investigational product bottle
well before every use.
The randomized investigational product kits to be dispensed will consist of a box with 
four dropper bottles, labeled Bottle 1 through Bottle 4.
At Visit 2, eligible subjects’ parents/caregivers will receive an investigational product kit
containing four bottles. Parents/caregivers will be instructed to dose with 1-2 drops of 
Bottle 1 in the morning, followed by 1-2 drops of Bottle 2 at midday, 1-2 drops of Bottle 
3 in the afternoon, and 1-2 drops of Bottle 4 at bedtime. This treatment schedule will be 
followed for 29 days ± 2 days. All bottles should be stored upright and shaken well
before dosing.
Subjects randomized to KPI-121 1% will receive investigational product kits containing 
both KPI-121 1% (Bottles 1 and 4) and vehicle (Bottles 2 and 3). Thus, the treatment 
schedule will result in QID dosing with 2 of the doses KPI-121 1% and 2 of the doses 
vehicle.
Subjects randomized to prednisolone acetate 1% will receive kits with 4 bottles of 
prednisolone acetate 1%, for QID dosing.
Subject’s parent/caregiver will return their kits (and bottles) and receive a new kit 
containing the same product at Visit 4 to ensure sufficient investigational product through 
Visit 5. At Visit 5 they will return their second kit and end investigational product use. 
Completion of investigational product use may be followed by treatment or taper with a 
commercially available product as determined by the Investigator.

All kit labels and dropper bottle labels will contain the following information: sponsor 
name, protocol and kit number, storage temperature, and required statement(s) per the 
appropriate regulatory agency. The dropper bottle labels will also be printed with the 
bottle number (e.g., Bottle 1, Bottle 2, etc.).
Subjects’ parents/caregivers will be instructed to shake the investigational product bottle
well prior to administering each dose.  When subjects receive the first dose administered 
in the clinic, the dose will count as one of the daily doses. Parents/caregivers will then 
administer the additional doses of investigational product later that day, according to the 
dosing schedule and instructions provided by the dosing coordinator.
The Investigator will store all investigational product upright in a secure area, with 
limited access, at controlled room temperature (15-25qC/59 -77qF). Parents/caregivers 
will be instructed to store the investigational product upright at room temperature.

Methods to Minimize Bias
To minimize bias, the following measures will be taken:
x
Investigational product assignment (KPI-121 1% ophthalmic suspension
or prednisolone acetate ophthalmic suspension 1%) will be randomized 
and masked to the sponsor, subjects, and investigative staff with the 
exception of a dedicated dosing coordinator. The dedicated dosing 
coordinator will manage drug dispensing and return, parent/caregiver 
instruction and initial dosing and will review the dosing diary. Since the 
KPI-121 1% ophthalmic suspension is only dosed BID, it will be 
supplemented with BID dosing of vehicle to support the masking.
x
The randomization schedule will be generated by the randomization 
statistician (who is not on the project team) or designee and maintained via 
the electronic data capture system (EDC) used for the trial.

SUBJECT WITHDRAWAL AND/OR DISCONTINUATION 
Any parent/guardian who wishes to discontinue their child’s investigational product use 
or withdraw their child from participation in the study for any reason is entitled to do so 
without obligation.  The Investigator may also discontinue any subject from 
investigational product use or from study participation, if deemed necessary. 
Investigational product use may be discontinued, and any subject may be discontinued 
from study participation at any time during the study at the discretion of the Investigator 
or the sponsor for any reason including but not limited to:
1. Occurrence of any medical condition or circumstance that exposes the 
subject to substantial risk and/or does not allow the subject to adhere to 
the requirements of the protocol.
2. Any SAE, clinically significant AE, severe, intercurrent illness, or other 
medical condition that indicates to the Investigator that continued 
participation is not in the best interest of the subject.
3. Parent’s/guardian’s decision to withdraw.
4. Parent’s/caregiver’s failure to comply with protocol requirements or study 
related procedures.
5. Termination of the study by the Sponsor, FDA, or other regulatory 
authorities.
In the event study discontinuation of a randomized subject is necessary, the Investigator 
should make every attempt possible to have the subject complete the Early Termination
assessments.  The Investigator should make every attempt to follow all serious adverse 
events (SAEs) to resolution.  The reason for premature discontinuation should be 
recorded in the subject’s chart.

Subjects who withdraw from the trial will not be replaced.
Additionally, the trial or parts of the trial may be discontinued by the sponsor or at the 
recommendation of the Investigator after consultation with Kala Pharmaceuticals, Inc.  
This may be based on a significant number of AEs of a similar nature that warrant such 
action.
5.3.
COLLECTION OF DATA
Source documentation for data collected in this study will be maintained at the investigative 
site.  The CRF will be electronic (eCRF) and data will be electronically entered from the 
source documentation into the eCRF. After study completion, an archival copy [e.g., 
portable document format (PDF)] of the eCRF data will be retained by the site.

RESCUE MEDICATION USE
Any subjects not responding adequately to the investigational product may be rescued 
and placed on alternate therapy at the Investigator's discretion at any time. The choice of 
rescue medication is at the Investigator's discretion. Any subject placed on rescue therapy 
will discontinue use of the investigational product and continue study participation 
through Visit 6.
Rescued subjects will be considered treatment failures, and the need for rescue therapy 
will not be considered an AE. Rescued subjects should not be withdrawn from the study, 
but rather followed through the end of the study/Visit 6.

TREATMENT OF SUBJECTS
6.1.
INVESTIGATIONAL PRODUCTS TO BE ADMINISTERED
KPI-121 1% and vehicle or prednisolone acetate 1% will be supplied as investigational 
product.  One Kit of randomized investigational product containing four dropper bottles 
will be allocated to each subject at Visit 2.
The investigational product will be stored at the site upright in a secure area, with limited 
access, at 15-25qC/59-77qF.
Parents/caregivers will be asked to administer investigational product four times daily
during the treatment phase. Instillation of the four doses should be spaced throughout the 
day at the approximate time points of: morning (Bottle 1), midday (Bottle 2), afternoon
(Bottle 3), and bedtime (Bottle 4). Prior to each instillation of investigational product, the 
parent/caregiver will be instructed to shake the investigational product bottle well. The 
parent/caregiver will record the time of administration and number of drops administered 
for each dose of investigational product in the Daily Dosing Diary (Appendix 7).
Additional investigational product will be dispensed at Visit 4 and discontinued at Visit 
5.  Used investigational product kits will be collected by the study staff at Visits 4 and 5.  
Compliance with instillation of investigational product will be assessed at each clinic 
visit and reviewed with the parent/caregiver if poor compliance is noted.
6.2.
CONCOMITANT MEDICATIONS
With the exception of peri-operative standard of care medications, all medication that the 
subject has taken 30 days prior to Visit 1 and through Visit 6 or discontinuation from the 
study will be recorded in the subject’s chart/source documents and the eCRF. The name 
of the drug, dose, route of administration, duration of treatment (including start and stop 
dates), frequency, indication, and whether or not the medication was taken due to an AE 
will be recorded for each medication.
6.2.1.
Permitted Medications
Medications not specifically excluded in Section 6.2.2 may be taken as necessary.
Concomitant treatment with ocular antibiotics at the discretion of the Investigator is 
allowed (with the exception of besifloxacin). Medications routinely administered (and 
not explicitly prohibited in this protocol) as part of an uncomplicated cataract surgery

product (e.g., dates, subject number, kit number dispensed, and kits and bottles returned) 
must be maintained by the Investigator or his/her designee. Investigational product will 
be stored upright in a secure area, with limited access, at 15-25qC/59-77qF.
At the end of the study, all investigational product (KPI-121 1%, vehicle and 
prednisolone acetate 1%), including all used and unused bottles and kits, will be returned 
to the drug packaging vendor in accordance with sponsor or designee’s standard 
operating procedures (SOPs), following approval by the Sponsor. All returns of
investigational product will be documented. The study monitor or designee will verify 
drug accountability. All drug accounting procedures must be completed before the study 
is considered complete.
6.5.
MAINTENANCE OF RANDOMIZATION AND PROCEDURE FOR BREAKING THE 
CODE
The sponsor, the project teams at the designated Contract Research Organizations 
(CROs), and investigative staff responsible for assessments of study endpoints will be 
masked to investigational product assignments. In case of medical emergency, or 
occurrence of an SAE, the randomization code may be unmasked and made available to 
the Investigator, sponsor, and/or other personnel involved in the monitoring or conduct of 
this study. In the absence of medical need, the randomization code will not be available 
to the above individuals until after the study is completed and the database is locked.  
In the event of a medical need, the Investigator will treat each subject as needed. Since 
there is no specific antidote to KPI-121 1%, immediate emergency unmasking is not 
necessary. If the Investigator feels it is necessary to unmask a subject’s assignment after 
an emergency situation, the Investigator may call the medical monitor and notify the 
sponsor. The investigational product assignment will be revealed on a subject-by-subject
basis with the approval of the medical monitor and sponsor, thus leaving the masking of 
the remaining subjects intact.

ADVERSE EVENT DEFINITIONS
Adverse Event (AE): Any untoward medical occurrence associated with the use of an 
investigational product in humans, whether or not considered drug related.
Adverse Reaction (AR): Any AE caused by a drug. Adverse reactions are a subset of all 
suspected adverse reactions where there is reason to conclude that the drug caused the 
event. 
Suspected Adverse Reaction (SAR): Any AE for which there is a reasonable possibility 
that the drug caused the AE. For the purposes of IND safety reporting, “reasonable 
possibility” means there is evidence to suggest a causal relationship between the drug and 
the AE. A SAR implies a lesser degree of certainty about causality than adverse reaction, 
which means any AE caused by a drug. 
Unexpected: An AE or SAR 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.
Life-threatening: An AE or SAR 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 or suspected adverse reaction that, had it occurred in a 
more severe form, might have caused death.

A SERIOUS ADVERSE EVENT (SAE) is any AE or suspected adverse reaction 
occurring at any dose that: 
x
Results in death.
x
Is life-threatening.
x
Results in a persistent or significant incapacity or substantial disruption of 
the ability to conduct normal life functions.
x

investigational product (unrelated, unlikely, possibly, probably, definitely). The AE will 
be assessed using the following definitions:
Unrelated:

Event or intercurrent illness due wholly to factors other than investigational 
product use.
Unlikely:

Poor temporal relationship with investigational product use.

Event easily explained by subject’s clinical state or other factors.

(NOTE: Expected changes such as the presence of inflammation resulting from routine 
uncomplicated cataract surgery will not be captured as AEs.)
8.3.
PROCEDURES FOR AE REPORTING BY THE INVESTIGATOR
AEs will be monitored throughout the study. AE reporting will start with the first dose of 
investigational product. AEs will be reported through the conclusion of Visit 6. AEs will 
be recorded on the CRF with the date and time of onset, date and time of resolution, 
severity, seriousness, causality (relationship to use of investigational product), treatment 
required, and the outcome. To elicit AEs, simple questions with minimal suggestions or 
implications should be used as the initial questions at all evaluation points during the 
trial.  For example:
x
How has your child felt since their last visit?
x
Has your child had any health problems since your last visit?
The severity of each AE should be categorized as mild, moderate, or severe.
The causality of use of investigational product in relation to the AE will be assessed by 
the Principal Investigator after careful medical consideration and categorized as 
unrelated, unlikely, possible, probable, or definite.
If an AE occurs, the Investigator will institute support and/or treat as deemed appropriate.  
If an AE is unresolved at the time of the last study visit, an effort will be made to follow 
up until the AE is resolved or stabilized, the subject is lost to follow-up, or there is some 
other resolution of the event.  The Investigator should make every attempt to follow 
SAEs to resolution.

STATISTICS
9.1.
STATISTICAL METHODS
Continuous measures (e.g., age) will be summarized descriptively by the mean, standard 
deviation, median, minimum and maximum values. Categorical measures will be 
summarized by the number and percent of subjects.
9.1.1.
Subject Disposition, Demographic and Background Characteristics
Subject disposition, demographic characteristics, and background variables will be 
summarized by study group.  
9.1.2.
Evaluation of Efficacy
The efficacy and safety evaluations will be based on a single study eye, defined as the 
surgery eye, for each subject. 
The primary analysis population will be the Intent-to-Treat (ITT) population, defined as 
all subjects randomized and with at least one post-baseline assessment. A subset of 
efficacy analyses will be repeated using data from those subjects who were randomized, 
completed 15 days ± 2 days of investigational product use, had complete data at Visit 4
(Day 15 ± 2 days), and did not have significant protocol deviations, the Per Protocol (PP)
population. Rescued subjects will be included in the PP population if they did not have 
significant protocol deviations, however, these subjects will be considered treatment 
failures.
No inferential statistical analyses are planned. Data will be summarized using descriptive 
statistics only. Assessment of efficacy will be based primarily on the number and 
percentage of subjects in each treatment group with an anterior chamber cell grade of 0 at 
Visit 4 (Day 15 ± 2 days) with no need for rescue medication through Visit 4 and,
secondarily, on the Modified Global Overall Assessment of Postoperative Inflammation 
score of 0 at Visit 4 (Day 15 ± 2 days) without receiving rescue medication prior to Visit 
4.
The individual components of the Global Assessment score will also be evaluated (i.e., 
number and percentage of subjects in each treatment group in each score category at each 
visit).
The following scoring scale for anterior chamber cells will be used:
0 = No cells seen
1 = 1 - 5 cells

Analysis of Safety
Analysis of safety data will be presented for all subjects in the Safety population (i.e., all 
subjects receiving randomized investigational product). AEs will be coded using Medical 
Dictionary for Regulatory Activities (MedDRA, version 21.0) and categorized by system 
organ class using preferred terms. AEs will be tabulated by study group with respect to 
their intensity and relationship to the investigational product. Ophthalmoscopy findings 
will be summarized descriptively. IOP measurements, Visual Acuity and Dilated 
Ophthalmoscopy assessments will be summarized as safety outcomes.
9.2.
SAMPLE SIZE ESTIMATION
Assessment of safety will be based on the assessment of AEs. To allow for at least a 95% 
chance of detecting an AE with a 10% incidence rate, a minimum sample size of 
30 subjects per group (KPI-121 1% or prednisolone acetate 1%) is required. All 
statistical analyses will be performed using Statistical Analysis System (SAS) software. 
9.3.
LEVEL OF SIGNIFICANCE
Only descriptive analyses are planned.
9.4.
PROCEDURE FOR ACCOUNTING FOR MISSING, UNUSED, OR SPURIOUS DATA
If more than 5% of data points are missing at the primary analysis time point (Day 15) in 
any treatment group, a tipping point analysis will be employed to assess the sensitivity of 
the results to the distribution of the allocation of treatment success and failure to the 
missing data points.
9.5.
PROCEDURE FOR REPORTING DEVIATIONS FROM THE STATISTICAL PLAN
Any deviations from the statistical analysis plan will be described and a justification 
given in the final clinical study report.
9.6.
SUBJECTS TO BE INCLUDED IN THE ANALYSIS
The primary analysis population will be the Intent-to-Treat (ITT) population, defined as 
all randomized subjects with at least one post-randomization assessment. A subset of 
efficacy analyses will be repeated using data from those subjects who were randomized, 
completed 15 days ± 2 days of investigational product use, had complete data at Visit 4
(Day 15 ± 2 days), and did not have significant protocol deviations, the Per Protocol (PP)

APPENDIX 3: ASSESSMENT OF SIGNS OF ANTERIOR OCULAR INFLAMMATION  
Signs of anterior ocular inflammation will be assessed by slit lamp biomicroscopy,
ophthalmoscopy or light examination depending on subject’s tolerance and as determined by the 
Investigator. It is recommended that a table-top slit lamp be used if at all possible. The use of a
portable slit lamp, ophthalmoscope or muscle light (transilluminator) should be reserved for 
subjects who cannot comply with the table-top slit lamp exam.
The same method will be used consistently for each subject (when possible).
The signs of anterior ocular inflammation will be performed at every study visit (when 
obtainable).
The following signs will be assessed:
Anterior Chamber Cells
0 = No cells seen
1 = 1 - 5 cells
2 = 6 - 15 cells
3 = 16 - 30 cells
4 = greater than 30 cells
Anterior Chamber Flare
0 = None
1 = Mild (trace to clearly noticeable, visible)
2 = Moderate (without plastic aqueous humor)
3 = Marked (with plastic aqueous humor)
4 = Severe (with fibrin deposits and/or clots)
Corneal Clarity
0 = Absent
1 = Mild
2 = Moderate
3 = Severe
Conjunctival Injection
0 = Absent
1 = Mild
2 = Moderate
3 = Severe

APPENDIX 4: IOP MEASUREMENT
IOP measurements will be performed utilizing an Icare rebound tonometer, or similar tonometer 
according to the Investigator’s standard procedure. All pressures will be recorded in mmHg.  
IOP will be assessed at all study visits (when obtainable, except at Visit 2 when this assessment 
is required). If unable to obtain a valid measurement by tonometer at Visit 2, assessment by other 
means, as determined by the investigator, will be accepted.

APPENDIX 5: DILATED OPHTHALMOSCOPY
Dilated ophthalmoscopy will include assessment of vitreous clarity, optic disc, vessels, retina, 
choroid, macula and periphery. Indirect ophthalmoscopy will be used. The Investigator will 
determine if findings are within normal limits or are abnormal.  For abnormal findings at Visit 1, 
the Investigator will determine whether or not the abnormality would exclude subject from study 
participation.
Dilated Ophthalmoscopy will be performed at Visit 1 and Visit 5 (when obtainable).
