Study Design & Summary of Visit Schedule: 
This Phase 3 study will evaluate APP13007 in comparison to the matching vehicle placebo in a 
randomized, parallel-group, double-masked fashion.  The subjects will have undergone routine 
cataract surgery on Day 0 of the study and will be assessed the next day (POD1) after 
uncomplicated surgery for eligibility for randomization to study treatment. The study comprises 
the Main Study and the Endothelial Cell Sub-study.  All randomized subjects (approximately 
370) will participate in the Main Study. The Endothelial Cell Sub-study will comprise a 
subgroup of approximately 176 subjects at study sites qualified to perform corneal endothelial 
cell parameter assessments.   
All eligible subjects at the qualified study sites for corneal endothelial cell assessments will be 
requested to participate in the Sub-study. If a subject is unable or unwilling to participate in the 
Sub-study, the Investigator has the option to enroll the subject in the Main Study only, after 
consulting with the Study Medical Monitor.   
Subjects who experience postoperative inflammation on POD1 and who meet all other eligibility 
criteria will be randomized to one of two study treatments (either Treatment 1 or Treatment 2) at 
a 1:1 ratio:   
 
Treatment 1:  1 drop APP13007 twice daily (BID) (morning and evening) for 14 days instilled to the 
operated study eye 
 
 
Treatment 2:  1 drop matching vehicle placebo BID (morning and evening) for 14 days instilled to the 
operated study eye

endothelial cell parameters in the study eye and assessment of adverse events and 
concomitant medications (approximately three months after starting the study drug). 
Final Visit for the Endothelial Cell Sub-study. 
A detailed summary of study events is provided in Table 1 (Schedule of Events) and a study design 
schematic is provided in Figure 1 (Study Schematics).   
Test Product, Dose and Mode of Administration:   
Study Drugs (APP13007 or matching vehicle placebo) will be supplied in an eye drop bottle. 
The formulations are preserved with benzalkonium chloride filled in a multi-dose opaque low 
density polyethylene (LDPE) 5 mL round dropper bottle with a LDPE tip and tightly closed with 
a pink high density polyethylene (HDPE) cap.  The bottle will be labelled in accordance with 
FDA regulations for an investigational product.   
One bottle of study drug will be dispensed to each randomized subject in the trial.  Study drug 
will be administered twice daily (morning and evening) by instilling one drop at each dosing 
time into the conjunctival sac of the study eye.  If the subject misses his/her eye during 
instillation, then a second drop will be instilled and this will be documented in the dosing diary. 
Randomization:  Subjects who meet all eligibility criteria on POD1 will be randomized to one of the 
two study treatments at a 1:1 ratio (APP13007:placebo).     
Number of Subjects:   
A sufficient number of subjects will be screened to allow approximately 370 subjects (~185 on 
APP13007 and ~185 on placebo) to be randomized. From all the randomized subjects, 
approximately 176 subjects (~88 on APP13007 and ~88 on placebo) will participate in the 
Endothelial Cell Sub-study at the participating study sites.   
Inclusion Criteria:

angle of resolution (logMAR) in the study eye to be operated and contralateral eye as measured 
using an Early Treatment Diabetic Retinopathy Study (ETDRS) chart at Visit 1. Subjects who are 
unable to read the lines in an ETDRS chart because of the density of the cataract in the study eye 
may be enrolled if, in the opinion of the Investigator, there is no other significant ocular pathology 
that would account for the low visual acuity. 
7. 
Willing and able to comply with study requirements and visit schedule; Able to either self-
administer study medication or have someone available (e.g., spouse, caregiver, etc.) who can 
administer study medication according to the study schedule and instructions.  
Additional Inclusion Criteria on Postoperative Day (POD) 1/Day of Randomization (Visit 2): 
8. 
The subject has undergone unilateral cataract extraction via phacoemulsification and posterior 
chamber intraocular lens implantation in the study eye without any additional procedures or 
complications that would, in the opinion of the Investigator, interfere with study procedures or 
confound study objectives.

To be eligible, a participant must meet the Inclusion and Exclusion criteria above. In 
addition, the following criteria apply: 
1. Subjects with Type 1 diabetes mellitus are excluded from the Endothelial Cell Sub-study. 
2. Subjects with a central corneal endothelial cell density <1800 cells/mm2 in either eye at the Screening 
visit are excluded from the Endothelial Cell Sub-study, but may participate in the Main Study. 
3. The first ~176 consecutively randomized subjects (~88 on APP13007 and ~88 on placebo) at the 
qualified participating sites will be requested to participate in the Endothelial Cell Sub-study. 
a. After the first ~176 consecutively randomized subjects at the qualified participating sites have 
been entered in the Endothelial Cell Sub-study, further subjects at these qualified sites may be 
entered in the Main study only if they meet the Inclusion and Exclusion criteria in Section 4.2

and Section 4.3, respectively. The Endothelial Cell Sub-study assessments described in Section 
3.2.1 are not performed. 
4. At the discretion of the Investigator, and after consultation with the Study Medical Monitor, a subject 
at a qualified participating site may be allowed to participate in the Main Study only if they are 
unable or refuse to return for the Visit 7 (POD85) assessments. In this case, the Endothelial Cell Sub-
study assessments described in Section 3.2.1 are not performed. Note: Prior to completion of the 
cohort of ~176 subjects in the Endothelial Cell Sub-study across all the qualified sites, no more than 
3 subjects should participate in the Main Study at one of the qualified participating sites without 
approval of the Sponsor. 
Statistical Methods: 
All analysis variables will be summarized descriptively by treatment group. Summary statistics 
for continuous measures will include the number of subjects (n), mean, standard deviation, 
median, and range. Categorical measures will be summarized by the number and percent of 
subjects.  
Analyses of Primary Efficacy Endpoints: 
The primary efficacy analyses to compare APP13007 against placebo will be conducted on the 
Intent-To-Treat (ITT) population using the Pearson Chi-square statistic. Fixed sequence testing 
will be employed to maintain the 2-sided alpha = 0.05. The primary analyses will first test the 
difference in the proportion of subjects with ACC count = 0 (Grade = 0) at POD8 (Visit 4) 
maintained through POD15 (Visit 5) between treatment groups. If the test is statistically 
significant at the 2-sided alpha = 0.05 level in favor of APP13007, the difference in the 
proportion of subjects with Ocular Pain Grade = 0 at POD4 (Visit 3) maintained through POD15 
(Visit 5) between treatment groups will be tested at the two-sided alpha = 0.05 level.  
Analyses of Secondary Efficacy Endpoints: 
Mean change-from-baseline in ACC Grade, Ocular Pain Grade, ACF Grade and visual acuity at 
PODs 4, 8 and 15 will be analyzed using an analysis of covariance (ANCOVA). The ANCOVA 
model will include treatment as a fixed effect and baseline as a covariate. The rest of the 
secondary efficacy endpoints will be analyzed using the same method described for the primary 
efficacy endpoints. Rescued subjects will be considered to be treatment failures. 
Safety Analysis: 
The safety analysis will summarize ocular treatment emergent AEs (TEAEs) in the study eye and ocular 
AEs for the non-study eye. Ocular and non-ocular TEAEs will be summarized similarly.  
 
The other safety endpoints, including corneal endothelial cell parameters (corneal endothelial cell 
density, percent hexagonality and coefficient of variation) will be summarized as discussed in the 
Statistical Considerations section of the protocol.

1 Ophthalmic assessments will be performed in the study eye only at Visits 2-5 and Visit 7 and performed on both eyes at Visit 1 (Screening) and at Visit 6 (POD22) or at subject Early Termination/Withdrawal. In the Endothelial Cell Sub-study, corneal 
endothelial cell parameters are measured in both eyes at Screening and in the study eye only at Visit 6 (POD22) and Visit 7 (POD85). 
2 Surgery must occur between one to 28 days after Screening, preferably in the morning.  If, due to unexpected events, surgery is postponed and would occur > 28 days past the Screening visit, contact the Study Medical Monitor to determine which, if any, 
of the screening procedures should be repeated. Subjects will be determined to be a suitable candidate for surgery during a pre-surgery medical assessment, where the routine medication list prescribed by the cataract surgeon should be reviewed to rule 
out prohibited medications (Section 5.4.2). 
3 Visit 2 (POD1) should be scheduled between 18 to 34 hours following conclusion of surgery on Day 0. All assessments done on POD1 are done prior to Randomization to ensure eligibility. Note: Women-of-childbearing-potential are eligible for enrollment 
if they have a negative urine pregnancy test on POD1 prior to Randomization and they agree to abstinence from sexual activity or use of highly effective method of contraception from POD1 to Visit 6 (POD22).. 
4 Visit 5 (POD15) occurs on the day after the subject completes the study drug administration for 14 days. Women-of-childbearing-potential should have a urine pregnancy test. 
5 Visit 6 (POD22) is the last visit for subjects participating in the Main Study only. Subjects who are withdrawn early should have the Visit 6 assessments and a urine pregnancy test, if applicable, performed before they are released from the study. 
6 Visit 7 (POD85) is the last visit for subjects participating in the Endothelial Cell Sub-study. Subjects in the Endothelial Cell Sub-study who are withdrawn early after POD22 should have the Visit 7 assessments performed before release. 
7 Includes assessments of ocular pain and irritation. See Section 8.0 of protocol for information on how to record AEs and how to determine attributability (relatedness) of AE to study procedures (including cataract surgery) or study drug. 
8 Ocular inflammation assessment using ACC count, anterior chamber flare grade, bulbar conjunctival injection, sclera - ciliary flush and corneal edema. 
9 IOP should (but not required) be assessed at each visit within ± 2 h of the IOP assessment time at Visit 1. 
10 Only performed in the subjects in the Endothelial Cell Sub-study at participating centers. The parameters are: endothelial cell density (cells/mm2), percent hexagonality and coefficient of variation. Performed in both eyes at the Screening visit and in the 
study eye at Visit 6 (POD22) and Visit 7 (POD85). 
11 The first dose of study drug should be instilled into the study eye at the clinic visit under supervision of clinic staff. The second dose on POD1 can be administered at home. Subjects who are rescued will not continue to instill study drug or receive further 
diary cards but will remain in the study to complete the procedures/assessments through Visit 6 (POD22) (Main Study) or Visit 7 (Endothelial Cell Sub-study).  
12 The site must contact the subject via the subject’s preferred method on POD14 to remind him/her not to instill study drug on POD15 and to bring the bottle of study drug and the dosing diary back to the site at the POD15 visit. In addition, the subjects in 
the Endothelial Cell Sub-study will be sent US mail/email/voicemail/text message reminders on ~POD50 and ~POD78 to return for Visit 7 (POD85). 
13 Concomitant medications used for rescue should be reported in the eCRF. 
14 AEs and Concomitant Medications should only be recorded on Day 0 if they result in disqualification (i.e., screen failure) of the subject; otherwise, the AEs and Concomitant Medications applicable to Day 0 should be recorded when the subject returns for 
Visit 2 (POD1). 
15 Any AEs reported to the site during the POD14 contact or as a result of the POD50/POD78 reminders must be recorded in the source documents.  Further assessment of any reported AEs may require an Unscheduled Visit if medically significant or they 
may be assessed, as appropriate, during Visit 5 (POD15) or Visit 7 (POD85), respectively.

INTRODUCTION 
1.1 
OVERVIEW 
APP13007 is an ophthalmic nanosuspension that is prepared by dispersing 
 
, a corticosteroid, with a mixture of excipients in a multi-dose preserved aqueous 
 
1.2 
BACKGROUND 
1.2.1 
 
Corticosteroids regulate cellular signaling, immune function, inflammation and protein synthesis, 
and like other corticosteroids, CP has anti-inflammatory and vasoconstrictive properties.  The 
mechanism of the anti-inflammatory activity of CP is unclear, but it is thought to act by inducing 
lipocortins, proteins that inhibit phospholipase A2, an enzyme that releases arachidonic acid 
from membrane phospholipids.  By inhibiting phospholipase A2, lipocortins control the 
biosynthesis of potent mediators of inflammation such as prostaglandins and leukotrienes. 
CP is an analog of prednisolone with a very high degree of activity at the glucocorticoid receptor 
and only slight degree of mineralocorticoid activity (Clobex® 2018).  It is reported to be the most 
potent corticosteroid in terms of binding affinity to the glucocorticoid receptor and resulting 
pharmacological effects (Olsen 1986), (Jacob 2006).  CP has been used in dermal applications 
including ointments, creams and shampoos, where its efficacy and safety has been well-
established (Clobex® 2018); (Temovate® 2000); (Olsen 1986); (Hengge 2006); (Feldman 2009). 
1.2.2 
Pain and Inflammation Following Cataract Surgery 
Despite modern advances in surgical technique, trauma that occurs during cataract removal and 
intraocular lens placement regularly leads to some degree of inflammation.  The cellular damage 
on the surface of the cornea activates an inflammatory process that manifests initially as 
hyperemia, corneal edema, and increased anterior chamber cells and flare.  More serious 
complications such as corneal edema, increases in intraocular pressure (IOP), cystoid macular 
edema, and posterior capsule opacification may result if the inflammatory process is not 
managed appropriately (Tennant 1978) (Apple 1992).  For this purpose, a post-cataract surgery 
regimen of anti-inflammatory agents (such as corticosteroids) is typically prescribed because it 
reverses inflammation, pain and discomfort and reduces the risk of further complications.  When 
administered at the time of surgery and during the immediate postoperative period,

corticosteroids can reverse the clinical and non-clinical manifestations of inflammation (Leopold 
1985) (Aptel 2017). 
1.2.3 
Rationale for Development of APP13007 
Topical ocular administration of corticosteroids is a well-established therapy for the treatment of 
inflammation and pain after ocular surgery (Aptel 2017), and several marketed products are 
currently available that contain active ingredients such as dexamethasone, prednisolone, 
loteprednol etabonate and difluprednate.   
CP has been used for over 30 years in the US, Europe and Japan to treat the inflammatory and 
pruritic manifestations of corticosteroid responsive dermatoses such as psoriasis, eczema and 
atopic dermatitis.  CP has not been previously developed for ophthalmic use, presumably due to 
its lack of aqueous solubility.  Nevertheless, given its increased potency, an aqueous ophthalmic 
formulation of CP has the potential to produce rapid clearance of anterior chamber cells (ACC), 
return of visual acuity and relief of pain after ocular surgery, surpassing the effectiveness of 
corticosteroids currently on the market.   
APP13007 is an ophthalmic nanosuspension that is prepared by dispersing nanomilled CP with a 
mixture of excipients.  The proprietary nanomilling technology allows CP to be formulated as an 
aqueous suspension.  This suspension of CP nanoparticles in APP13007 is designed to promote 
efficient penetration of CP into the eye upon ocular surface instillation, thus delivering 
therapeutically relevant concentrations of CP to the target tissues within the eye. 
1.3 
NONCLINICAL STUDIES 
Multiple nonclinical pharmacology, pharmacokinetics, and toxicology studies have been 
conducted with various formulations of APP13007, and these are summarized in the APP13007 
Investigator Brochure.

Toxicology 
 
 
 
 
 
 The toxicology studies suggest that 
potential systemic effects in human subjects with ocular instillations of APP13007 are those 
typical of corticosteroids in general and that have been seen with approved dermal CP products, 
such as Temovate® and Clobex® (Temovate® 2000); (Clobex® 2018). 
The data from repeat dose toxicology studies did not identify any unacceptable risk for human 
subjects.   
1.4 
HUMAN STUDIES 
Two clinical studies have been completed with APP13007, and details of the subject populations, 
study dosing, conduct and results are summarized in the APP13007 Investigator Brochure. 
1.4.1 
CPN-201: A Phase 2 Safety and Preliminary Efficacy Study Post Cataract 
Surgery  
This was a multi-center, randomized, double-masked, placebo-controlled, parallel-group Phase 2 
study conducted in two parts (Parts A and B) to evaluate two APP13007 dose strengths and two 
dosing frequencies in subjects who had undergone routine cataract surgery and lens implantation.  
On Post-Operative Day 1 (POD1), subjects who met eligibility criteria were enrolled in the study

and randomized  to one of the study treatments instilled in the operated study eye: Treatment 1 or 
2 in Part A (1:1 ratio); Treatment 3, 4, 5, or 6 in Part B (1:1:1:1 ratio).  A total of 45 subjects 
were randomized in Part A and 87 subjects randomized in Part B. 
 Treatment 1:  1 drop 0.05% APP13007 BID for 21 days  
 Treatment 2:  1 drop 0.05% matching vehicle placebo BID for 21 days  
 Treatment 3:  1 drop 0.05% APP13007 BID for 3 days followed by 1 drop 0.05% APP13007 
QD for 11 days  
 Treatment 4:  1 drop 0.05% matching vehicle placebo BID for 3 days followed by 1 drop 
0.05% matching vehicle placebo QD for 11 days  
 Treatment 5:  1 drop 0.1% APP13007 BID for 3 days followed by 1 drop 0.1% APP13007 
QD for 11 days   
 Treatment 6:  1 drop 0.1% matching vehicle placebo BID for 3 days followed by 1 drop 0.1% 
matching vehicle placebo QD for 11 days  
1.4.1.1 Safety Results   
The 0.05% APP13007 and 0.1% APP13007 dosing regimens were well-tolerated with a safety 
profile similar to the matching placebo vehicles.

1.5.1.2 
Potential Risks Anticipated Based on Results from the Human Studies with 
APP13007 
As summarized in the APP13007 Investigator Brochure and in Section 1.4.1.2 and Section

 the 
systemic tolerability profile after ocular instillation of 0.05% APP13007 BID for 14 days is 
expected to be considerably better than that for dermal CP products summarized below.  
1.5.1.3 
Potential Risks Associated with the Use of CP in the Treatment of 
Corticosteroid-Responsive Dermatoses 
There is extensive experience with CP in the treatment of inflammatory and pruritic 
manifestations of corticosteroid-responsive dermatoses, where its safety and anti-inflammatory 
profile has been well defined (Olsen 1986); (Hengge 2006); (Feldman 2009).  These risks are 
summarized in the APP13007 Investigator’s Brochure. 
Potential non-ocular risks include: 
 Hypothalamic-Pituitary-Adrenal (HPA) Axis Suppression.  Recovery of HPA axis 
function is generally prompt upon discontinuation of topical corticosteroids.   
 Cushing's syndrome, hyperglycemia, and unmasking of latent diabetes mellitus. Use of 
more than one corticosteroid-containing product at the same time may increase the total 
systemic corticosteroid exposure. 
 Skin:  Allergic contact dermatitis may occur.   
 Pregnancy and Nursing (Breast-feeding) Mothers:  
o Corticosteroids are teratogenic in laboratory animals when administered 
systemically at relatively low dosage levels (Pregnancy Category C). When 
administered subcutaneously, CP was a significant teratogen in both the rabbit 
and mouse.  Females of child-bearing potential are eligible to participate in this

study only if they have a negative urine pregnancy test on POD1 pre-
randomization and they agree to use highly effective contraception or abstain 
from sexual activity from POD1 to POD22. Note: Pregnant and/or nursing 
(breast-feeding) mothers are excluded from participation in this study.   
o Systemically administered corticosteroids appear in human milk and could 
suppress growth, interfere with endogenous corticosteroid production, or cause 
other untoward effects.  It is not known whether ocular administration of 
APP13007 could result in sufficient systemic absorption of CP to produce 
detectable concentrations in human milk. 
Potential ocular risks are summarized below. 
1.5.1.4 
Potential Class-Related Ocular Risks Associated with Corticosteroid Therapies 
for the Treatment of Ocular Inflammation and Pain after Ocular Surgery 
The active ingredient in APP13007, 
, is a potent corticosteroid so it has the following 
anticipated ocular risks associated with the corticosteroid class: 
 Intraocular pressure (IOP) increase – prolonged use may result in glaucoma with damage 
to the optic nerve, defects in visual acuity and field of vision.  
 Cataracts – Prolonged use 
 may result in posterior subcapsular cataract 
formation in the non-operated eye.   
 Delayed healing – Use 
 after cataract surgery may delay healing and 
increase the incidence of bleb formation.  In those diseases causing thinning of the cornea 
or sclera, perforations have been known to occur with the use of topical corticosteroids.  
 Risk of Infection 
 Bacterial infections – Prolonged use 
 may suppress the host immune 
response and thus increase the hazard of secondary ocular infections.  In acute 
purulent conditions, corticosteroids may mask infection or enhance existing infection. 
 Viral infections – Use of ocular corticosteroids may prolong the course and may 
exacerbate the severity of many viral infections of the eye (including herpes simplex).  
 Fungal Infections – Fungal infections of the cornea are particularly prone to develop 
coincidentally with long-term local corticosteroid application.  Fungus invasion must 
be considered in any persistent corneal ulceration while a subject is participating in 
this clinical trial.

In clinical studies evaluating the use of corticosteroids after ocular surgery, ocular adverse 
reactions that occurred in 5% to 15% of subjects included corneal edema, ciliary and 
conjunctival hyperemia, eye pain, photophobia, posterior capsule opacification, anterior chamber 
cells, anterior chamber flare, conjunctival edema, and blepharitis.  Other ocular adverse reactions 
occurring in 1% to 5% of subjects included reduced visual acuity, punctate keratitis, eye 
inflammation, and iritis.  Ocular adverse reactions occurring in less than 1% of subjects included 
application site discomfort or irritation, corneal pigmentation and striae, episcleritis, eye pruritus, 
eyelid irritation and crusting, foreign body sensation, increased lacrimation, macular edema, 
sclera hyperemia, and uveitis.  Most of these reactions may have been the consequence of the 
surgical procedure.

Risk Mitigation Plan 
Given the potential risks noted above, a risk mitigation plan will be used to mitigate risks for 
subjects enrolled into the study.  The Risk Mitigation Plan is shown in Table 2. 
1.5.3 
Contraindications 
 
APP13007, as with other corticosteroids, is contraindicated in the presence of active viral 
diseases of the cornea and conjunctiva including epithelial herpes simplex keratitis (dendritic

keratitis), vaccinia, and varicella, and also in subjects with mycobacterial infection of the eye and 
fungal diseases of ocular structures. 
APP13007 must not be administered (i) to women of child-bearing potential without a negative 
urine pregnancy test on POD1 prior to randomization and agreement to use highly effective 
contraception or abstain from sexual activity from POD1 to POD22 or (ii) to pregnant or nursing 
(breast-feeding) woman. 
1.5.4 
Potential Benefits 
Topical ocular administration of corticosteroids is a well-established therapy for the treatment of 
inflammation and pain after ocular surgery, with multiple marketed products currently available 
that utilize corticosteroids as the active ingredient such as dexamethasone (Maxidex®), 
prednisolone (PredForte®), loteprednol etabonate (Lotemax®, Inveltys®, Lotemax SM®), and 
difluprednate (Durezol®). In all clinical trials, corticosteroid therapies were dosed at a frequency 
of twice daily or more frequently.    
As summarized in the APP13007 Investigator’s Brochure, in Study CPN-201 a greater 
proportion of subjects treated with APP13007 0.05% BID had complete clearing of anterior 
chamber cells and complete resolution of ocular pain compared to placebo-treated subjects. 
Thus, it is likely that subjects randomized to active APP13007 will experience a clinically-
meaningful reduction in inflammation and pain following cataract surgery. 
It is known from large clinical trials of products for the treatment of inflammation and pain after 
ocular surgery that a proportion of subjects randomized to placebo improve in the days following 
surgery (Lotemax® Product Insert 2018; Durezol® Product Insert 2017).  Thus, there may be a 
marginal benefit observed in some of the subjects enrolled into the study who are randomized to 
the matching vehicle placebo. 
1.5.5 
Assessment of Potential Risks and Benefits 
This is a placebo-controlled study in which subjects will be randomized 1:1 to APP13007 or 
matching vehicle placebo.  Subjects randomized to active APP13007 may benefit from the 
treatment by reduction in inflammation and pain, while the risks associated with active 
APP13007 treatment are likely to be low and manageable.  This assessment is supported by the 
results of the nonclinical (See Section 1.3) and clinical studies (See Section 1.4) that are 
summarized in detail in the APP13007 Investigator’s Brochure. 
Subjects randomized to placebo are not expected to benefit from the study treatment, but a 
proportion of subjects receiving placebo may show improvement of inflammation in the days 
following surgery.  Furthermore, the risks to subjects randomized to placebo in this study are 
mitigated as much as possible.  Specifically, the protocol contains instructions for careful

monitoring of safety and efficacy endpoints during the trial to identify subjects who show 
minimal improvement or worsening of the clinical conditions so that appropriate mitigation steps 
can be taken, including, but not limited to, withdrawal from study treatment and commencement 
of appropriate rescue medication. 
Overall, the risk:benefit analysis supports the evaluation of 0.05% APP13007 and matching 
vehicle placebo administered BID for 14 days after cataract surgery.

Risk Associated with Unexpected Safety Events 
Unexpected safety events  
Safety endpoints will be monitored 
during the trial.  
 
The Investigator will discuss 
unexpected safety events with the 
Study Medical Monitor who will 
then discuss unexpected safety 
events with the Sponsor to 
determine whether study drug 
should be stopped and rescue 
procedures commenced.   
The toxicology studies with 
APP13007 indicate that there is a 
low risk of ocular toxicity. The risks 
of systemic exposure to CP 
following dermal application are 
well characterized. 
 
 
 
 
 
.  
 
Nevertheless, the Investigator 
should be alert to the possibility that 
unexpected safety events may occur. 
The list of expected safety events is 
including in Section 1.5.1 and in the

Comments 
Risks Associated with the Corticosteroid Class 
Intraocular pressure (IOP) 
increase 
IOP will be monitored during the 
study. 
 
The protocol excludes subjects who 
may be at increased risk of steroid-
induced IOP increase, e.g. subjects 
with a history of raised 
IOP/glaucoma and subjects with 
IOP >30 mmHg at the POD1 pre-
randomization assessment.   
 
Section 9.5 includes stopping 
criteria for study drug due to IOP 
increase and criteria for initiation 
of IOP-lowering medication. 
 
After Randomization, the 
management of IOP > 30 mmHg or 
IOP ≥ 21 mmHg AND an IOP 
increase > 10 mmHg from pre-dose 
baseline is described in Section 
9.5.2. 
There was no clinically-meaningful 
APP13007-related elevation of IOP 
in the toxicology studies and in 
Study CPN-201. 
 
Prolonged use of CP may result in 
glaucoma with damage to the optic 
nerve, defects in visual acuity and 
fields of vision.  
 
An IOP ≥ 30 mmHg after 
randomization should be reported as 
an AE. 
Cataracts 
The lens structure and posterior 
capsular opacification (POC) in the 
study eye will be monitored at each 
clinic visit throughout the study.  
The lens in the non-operated eye 
will be evaluated at Screening, 
Visit 6 (POD22) and Early 
Termination/Withdrawal visits. 
 
 
 
Delayed Healing 
Subjects with thinning of the 
cornea or sclera are excluded 
because of the greater risk of 
perforations with the use of topical 
steroids.  
 
Protocol includes stopping criteria 
for study drug if the Investigator, in 
consultation with the Study 
Medical Monitor, is concerned 
about delayed healing. 
Use of APP13007 may delay 
healing after cataract surgery and 
increase the incidence of bleb 
formation. There were no reports of 
delayed healing after cataract 
surgery in Study CPN-201.

Comments 
Risk of Infection 
Subjects with on-going ocular 
bacterial, viral or fungal infections 
are excluded from the study. 
 
Ocular infections occurring during 
the study should be assessed and 
treated appropriately.   
 
The Investigator should discuss 
with the Study Medical Monitor 
whether to stop study drug if ocular 
infection occurs. 
Use of APP13007 may suppress the 
host immune response and increase 
the hazard of ocular infections.  This 
risk is likely to be low based on data 
from studies of other steroids 
products approved for the treatment 
of inflammation and pain after 
ocular surgery. 
Hypothalamic-Pituitary-
Adrenal Axis (HPA) 
Suppression 
Monitor for symptoms and signs of 
reduced adrenal function (including 
fatigue, muscle weakness, loss of 
appetite and weight, abdominal 
pain, nausea and diarrhea, low 
blood pressure, depression and 
irritability, salt craving and 
hypoglycemia). 
 
The Investigator should discuss 
with the Study Medical Monitor 
who will then discuss with the 
Sponsor whether to stop study 
drug. 
While systemic absorption of topical 
corticosteroids can produce 
reversible HPA axis suppression 
with the potential for glucocorticoid 
insufficiency after withdrawal from 
treatment, this risk is likely to be 
very low 
 
 
 
 
 
 
 
 
Nevertheless, Investigators should 
be aware that the symptoms and 
signs of reduced adrenal function 
can be nonspecific and they should 
remain alert to the possibility that 
this may occur.  
Effects related to excessive 
corticosteroid pharmacology 
Monitor for symptoms and signs of 
excess corticosteroid pharmacology 
such as Cushing's syndrome, 
hyperglycemia, and unmasking of 
latent diabetes mellitus. 
 
The Investigator should discuss 
with the Study Medical Monitor 
who will then discuss with the 
Sponsor whether to stop study 
drug. 
These effects have been reported 
after dermal use of CP and result 
from systemic absorption of topical 
CP.

STUDY DESIGN 
3.1 
STUDY DESIGN OVERVIEW 
This Phase 3 study will evaluate APP13007 in comparison to the matching vehicle placebo in a 
randomized, parallel-group, double-masked fashion.  The subjects will have undergone routine 
cataract surgery on Day 0 of the study and will be assessed the next day (POD1) after 
uncomplicated surgery for eligibility for randomization to study treatment. The study comprises 
the Main Study and the Endothelial Cell Sub-study.  All randomized subjects (approximately

370) will participate in the Main Study. The Endothelial Cell Sub-study will comprise a 
subgroup of approximately 176 subjects at study sites qualified to perform the assessment of 
corneal endothelial cell parameters (endothelial cell density [cells/mm2], percent hexagonality 
and coefficient of variation).  All eligible subjects at the participating study sites for corneal 
endothelial cell assessment will be requested to participate in the Sub-study.  If a subject is 
unable or unwilling to participate in the Sub-study, the Investigator has the option to enroll the 
subject in the Main Study only (see Section 4.4 for more details). 
Subjects who experience postoperative inflammation on POD1 and who meet all other eligibility 
criteria will be randomized to one of two study treatments (either Treatment 1 or Treatment 2) at 
a 1:1 ratio:   
 Treatment 1:  1 drop APP13007 BID (morning and evening) for 14 days instilled to the 
operated study eye 
 
 Treatment 2:  1 drop matching vehicle placebo BID (morning and evening) for 14 days 
instilled to the operated study eye 
3.2 
STUDY VISIT OVERVIEW 
This study will include up to 7 scheduled clinic visits (including the surgery day) over a range of 
~ 24 to ~ 51 days for the subjects in the Main Study who are not participating in the Endothelial 
Cell Sub-study, while subjects in the Endothelial Cell Sub-study will have up to 8 scheduled 
clinic visits (including the surgery day) over a range of ~ 87 to ~ 114 days. 
Note:  
(i) 
The schedule of visits is the same for all randomized subjects from Visit 1 to Visit 6 
(ii) 
The study drug will be dosed BID for 14 days for all randomized subjects. 
3.2.1 
Study Visits and Assessments 
Visit 1: Screening. Sign informed consent prior to the conduct of any study procedures or 
discontinuation of any medications related to this study.  Screening will occur between 28 days 
to 1 day prior to cataract surgery. Review Inclusion and Exclusion criteria for eligibility.   
Between Screening and the day of surgery (Day 0), the prospective subjects will be determined 
to be a suitable candidate for surgery during a pre-surgery medical assessment, where the routine 
medication list prescribed by the cataract surgeon should be reviewed to rule out prohibited 
medications (see Section 5.4.2).

test, if applicable. 
Visit 6: POD22 (± 2 days). Ocular inflammation, pain and safety assessments. Final visit for the 
Main Study.   
Subjects who are not participating in the Endothelial Cell sub-study will be discharged from the 
study after the assessments for Visit 6 (POD22) have been performed. 
Additional Visits and Assessments for Subjects in the Endothelial Cell Sub-study at Qualified 
Study Sites 
In addition to the visits and assessments in the Main Study described above, ~176 subjects 
consecutively randomized to APP13007 or placebo at the participating sites will have the 
following extra assessments/procedures: 
 Visit 1 (Screening): Measurement of corneal endothelial cell parameters (endothelial cell 
density [cells/mm2], percent hexagonality and coefficient of variation) in both the 
planned study eye and non-study eye.  Collect information on contact lens use. 
 Visit 6 (POD22)/Early Termination: Measurement of corneal endothelial cell parameters 
in the study eye. 
 Subjects will be contacted twice (on ~ POD50 and ~ POD78) by USPS mail, email, 
voicemail or phone text after Visit 6 to remind them that they need to return for Visit 7.

RATIONALE FOR STUDY DESIGN 
3.3.1 
Rationale for Number of Subjects to be Randomized 
This is a Phase 3 study. See Section 10.4 for rationale for the number of subjects to be enrolled 
in the study. 
3.3.2 
Rationale for the Primary Efficacy Endpoints 
The two primary endpoints are clinically-meaningful to clinicians and the subjects undergoing 
ocular surgery and have been applied to support the approval of other corticosteroid ophthalmic 
drug products for the treatment of post-operative inflammation and pain following ocular 
surgery.  
The efficacy data from Part A of Study CPN-201 summarized in the APP13007 Investigator’s 
Brochure show that APP13007 0.05% BID, compared to matching vehicle placebo, produced a 
statistically and clinically-meaningful increase in the proportion of subjects who had an ACC 
Count = 0 at POD8 that was maintained through POD15.  
A greater proportion of subjects dosed with APP13007 as compared to placebo had resolution of 
ocular pain (grade = 0) at POD4 that was maintained through POD15.   
The US FDA has agreed with the primary endpoints in this study at an End-of-Phase 2 meeting.  
3.3.3 
Rationale for Dosing Regimen 
The results from Study CPN-201 summarized in the APP13007 Investigator’s Brochure show 
that 0.05% APP13007 BID as compared to its matching vehicle placebo produced a clinically-
meaningful reduction of inflammation and pain after cataract surgery.  In addition, all APP13007 

Clinical Study Protocol:  CPN-302 (Version 1.2, Amendment 1)

Page 46 of 95 
dosing regimens were well-tolerated with a safety profile similar to the matching vehicle 
placebos.  
These data support the selection of 1 drop of APP13007 0.05% administered BID for 14 days as 
the dosage regimen for this Phase 3 clinical study. 
The US FDA has agreed with the selection of the dosing regimen to be used in this study at an 
End-of-Phase 2 meeting.

4.2.1 
At the Screening Visit (Visit 1): 
1. Provide signed and dated informed consent 
2. Age ≥ 18 years at time of informed consent  
3. Males or females of non-childbearing potential.  Females of non-childbearing potential is 
defined as women who have been permanently sterilized or are postmenopausal.  
Postmenopausal is defined as amenorrhea for a minimum of 12 months (without an 
alternative medical cause).  Note: Pregnant women or nursing (breast-feeding) mothers 
are excluded from the study.  
4. Women-of-childbearing-potential to be eligible for enrollment if they have a negative

19. Have previous ocular trauma with visible scarring or any deformities due to the trauma in 
the study eye that in the opinion of the Investigator may affect the pharmacokinetics of 
the study drug, or post-surgical outcome (including, but not limited to intraocular 
inflammation, IOP or the normal healing process). 
20. Require the use of a contact lens or a collagen shield within 72 hours prior to cataract 
surgery or for the remainder of the study period in either eye. 
21. Require use of non-diagnostic topical ophthalmic medications in either eye for the 
duration of the study with the exception of the following which are allowed: mydriatics, 
anesthetics, antiseptics, balanced salt solution, viscoelastics, osmotic agents (e.g., Muro 
128), prophylactic antibiotics, non-prostaglandin analog IOP-lowering agents for IOP 
increases on the day of cataract surgery, lid scrubs for mild blepharitis, or artificial tears 
for the management of mild dry eye. 
22. In the opinion of the investigator, have the potential for ocular hemorrhage in the study 
eye that may interfere with evaluation of post-surgery inflammation. 
23. Have a planned use of or use of femtosecond laser or any other ophthalmic surgical 
procedure (e.g., vitrectomy, relaxing incisions, iridectomy, conjunctival excisions, use of 
iris hooks or other iris dilators, etc.) in addition to the cataract extraction procedure via 
phacoemulsification and posterior chamber intraocular lens implantation in the study eye. 
24. Have a planned use of or use anterior capsule staining for capsulorhexis (i.e., trypan blue) 
during cataract surgery. 
25. Have planned to participate in another clinical trial during the duration of this study. 
26. Have participated in another clinical study or received any investigational product within 
the past 28 days prior to the Screening Visit. Subjects who previously participated in 
Study CPN-201 are eligible if the planned cataract surgery is for the eye that was the 
‘non-study’ eye in that study.  
27. Have any other condition that the Investigator determines should exclude the subject 
from the trial. 
28. Are an employee of the clinical site that is directly involved in the management, 
administration, or support of this study or are an immediate family member of the same.

ADDITIONAL CONSIDERATIONS FOR THE ENDOTHELIAL CELL SUB-
STUDY 
To be eligible, a participant must meet the Inclusion and Exclusion criteria in Section 4.2 and 
Section 4.3, respectively. In addition, the following criteria apply: 
1. Subjects with Type 1 diabetes mellitus are excluded from the Endothelial Cell Sub-study. 
2. Subjects with a central corneal endothelial cell density <1800 cells/mm2 in either eye at 
the Screening visit are excluded from the Endothelial Cell Sub-study, but may participate 
in the Main Study. 
3. The first ~176 consecutively randomized subjects at the qualified participating sites (~88 
on APP13007 and ~88 on placebo) will be requested to participate in the Endothelial Cell 
Sub-study. 
a. 
After the first ~176 consecutively randomized subjects at the qualified 
participating sites have been entered in the Endothelial Cell Sub-study, further 
subjects at these qualified sites may be entered in the Main study only if they meet 
the Inclusion and Exclusion criteria in Section 4.2 and Section 4.3, respectively. 
The Endothelial Cell Sub-study assessments described in Section 3.2.1 are not 
performed. 
4. At the discretion of the Investigator, after consultation with the Study Medical Monitor, a 
subject at a qualified participating site may be allowed to participate in the Main Study 
only if they are unable or refuse to return for the Visit 7 (POD85) assessments. In this 
case, the Endothelial Cell Sub-study assessments described in Section 3.2.1 are not 
performed. Note: Prior to completion of the cohort of ~176 subjects in the Endothelial 
Cell Sub-study across all the qualified sites, no more than 3 subjects should participate in

treatment period.  If the subject discontinues study drug, the study drug bottle should be 
collected at the next clinic visit. 
If a subject loses the single bottle of study drug or if it becomes compromised (e.g., damaged or 
dropped into the toilet) prior to the POD15 visit, the bottle of study drug should be replaced as 
soon as possible.  The site should use the IWRS system to identify a replacement bottle.  
Subjects are instructed to notify the study site as soon as the study drug bottle is lost or 
compromised, so that the site can arrange for the replacement bottle to be provided as soon as 
possible.  Any missed doses due to loss of study drug bottle will be documented in the diary and 
eCRF.  
Failure to dose from the replacement bottle (issued prior to POD 15) will be considered a 
protocol deviation. 
5.1.2.2 
Subject Diaries 
A study diary will be given to each subject at the visits indicated on the Schedule of Events 
(Table 1).  The subject will record the date and time of each dose of study drug as well as the 
number of drop(s) instilled correctly into the conjunctival sac of the study eye at each dosing 
time.  The diary will remind the subject to instill the study drug a minimum of 5 minutes prior to 
administration of other eye medications in the study eye.  
At each study visit noted in the Schedule of Events, site personnel will collect the diary and 
dispense a new diary to the subject.  Site personnel will review the diary to ensure compliance 
with drug dosing and diary recording procedures.  Diary data will be entered into the eCRF.  If 
there is an issue with dosing or recording compliance, site personnel will instruct the subject 
again on correct procedures at each visit.  If the subject is unable to comply with required dosing 
procedures, the subject may be discontinued from the study.  However, site personnel must 
contact the Study Medical Monitor prior to discontinuing a subject for compliance-related issues. 
5.1.2.3 
Study Drug Compliance 
Site personnel will record the dosing record taken from the diary into the eCRF.  This will 
include the number of drop(s) correctly applied in the study eye, date/time of application and 
verification that no other drugs were administered within 5 minutes of study drug application in 
the study eye.  If patient states that other drugs were administered in the study eye within 5 
minutes of instillation of study drug, this will be recorded in the eCRF as a protocol deviation.  
Instillation of the study drug in the non-study eye will be recorded as a protocol deviation.

Study Treatments 
The treatments are as follows:  
 Treatment 1:  1 drop APP13007 twice daily (BID) (morning and evening) for 14 days 
instilled to the operated study eye 
 Treatment 2:  1 drop matching vehicle placebo BID (morning and evening) for 14 days 
instilled to the operated study eye 
5.1.2.5 
Study Drug Dosing 
Study drug (APP13007 or matching vehicle placebo) will be supplied in an eye drop bottle with 
a drop tip, and the bottle is labeled in accordance with FDA regulations for investigational drug.  
One bottle will be dispensed to each subject throughout the study.  Study drug will be self-
administered twice daily as indicated per protocol by instilling one drop into the conjunctival sac 
near the medial corner of the operated (study) eye.   
If the subject misses the conjunctival cul-de-sac when dosing the first drop of study drug, the 
subject should use a tissue to wipe away the study drug around the eye, and then instill a second 
drop into the conjunctival cul-de-sac so that at least one drop of study drug is administered into 
the study eye.  If the second drop also misses the conjunctival sac, then the subject should record 
the missed dose in the diary, but should not instill a third drop. 
Study drug should be administered twice daily.  If other concomitant eye drops/drugs are to be 
instilled into the study eye, the study drug should be instilled first followed by a minimum of a 5 
minute lag time before any other ocular medications are applied to the study eye. 
After randomization, the first dose of study drug should be administered in the clinic on POD1 
so that the site personnel can ensure the subject is able to apply study drug correctly.  The second 
drop of the study drug on POD1 should be administered by the subject a minimum of 6 hours 
later. For all other days the first dose should be instilled in the morning and the second dose 
instilled a minimum of 6 hours, but preferably 8 to 12 hours, later.  The number of drops instilled 
and the date/time of instillation of each dose must be recorded by the subject in the subject’s 
diary.  Subjects will be instructed on POD1 of recording the necessary information on the diary 
on each dosing day. 
5.2 
STUDY DRUG RETURN AND ACCOUNTABILITY 
Study monitors 
 will conduct accountability of APP13007 
and matching vehicle placebo. Accountability will be ascertained by performing reconciliation 
between the number of bottles of study drug, along with bottle ID numbers, sent to the site and 

Clinical Study Protocol:  CPN-302 (Version 1.2, Amendment 1) 
Formosa Pharmaceuticals, Inc.

Page 55 of 95 
the number of bottles dispensed (used), unused or un-dispensed (along with bottle ID numbers) 
at the time of reconciliation.  In addition, the number of bottles of study drug (along with bottle 
ID numbers) dispensed and returned will also be accounted for. 
Clinical trial materials will be shipped to the investigational sites under sealed conditions with a 
temperature tracking device.  Study drugs shipment records will be verified by comparing the 
shipment inventory sheet to the actual quantity of study drug (number of bottles and bottle ID 
numbers) received at the site. Accurate records of receipt and disposition of the study drug 
(e.g., dates, number of bottles and each bottle ID number received, dispensed, lost or 
compromised, and returned) and subject number associated with the bottle ID number must be 
maintained by the Investigator or his/her designee. 
 
   
At the end of the study, all study materials, including any used (and returned) and unused study 
drugs bottles, even if empty, will be returned to the drug packaging and distribution vendor in 
accordance with Sponsor or designee’s standard operations procedures (SOPs), following 
approval by the Sponsor. All returns of study drugs 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. 
5.3 
MASKING AND UNMASKING 
The Sponsor, the management and project team at the CRO responsible for trial management, 
monitoring and data collection and management, the study monitors, the Study Medical Monitor, 
the study subjects, the Investigators and the study site staff responsible for managing and 
administering the study, communicating with the study subjects, and/or performing assessments 
of study endpoints will be masked to study treatment assignment of each subject throughout the 
entire study.   
The Study Medical Monitor will remain masked throughout the study unless unmasked 
information becomes necessary as part of the management of a medical emergency or SAE for a 
particular subject, as described below. 
A randomization schedule will be computer-generated by a qualified biostatistician independent 
of the study conduct and management and will be uploaded into the EDC system by a designated 
person not involved in the study conduct, data collection or management.  The EDC/IWRS 
system will be used for randomization and unmasking of treatment assignment when necessary.   
In case of a medical emergency or occurrence of an SAE, the Investigator will treat each subject 
as needed and should contact the Study Medical Monitor, if required, to discuss whether it is 
appropriate to unmask the subject to reveal the subject’s treatment assignment.  If deemed 
necessary, the Investigator will log into the EDC system to obtain unmasking information.  The 

Clinical Study Protocol:  CPN-302 (Version 1.2, Amendment 1)

Investigator must use their individual login information to gain access to the unmasking 
information. The Investigator will also notify the IRB and the CRO managing and monitoring 
this study when treatment assignment for a particular subject is unmasked.  The Study Medical 
Monitor will notify the Sponsor Medical Monitor when treatment assignment for a particular 
subject is unmasked due to a medical emergency or SAE.  It is important to note that the study 
treatment assignment will be revealed only on a subject-by-subject basis and the treatment 
assignment of the other subjects in the study, as described above, will remain masked until the 
final database is locked.  Once the treatment assignment for a specific subject is unmasked, it 
will be made available to the Investigator and the Sponsor.  Other personnel involved in the 
monitoring or conduct of this study will remain masked. 
5.4 
PRIOR/CONCOMITANT THERAPY AND RESCUE MEDICATION 
All prior/concomitant medications (prescription and OTC) a subject is receiving at the Screening 
visit and 90 days prior to the Screening visit and taken throughout the course of the study will be 
recorded as follows:    
 Information regarding the duration of a prior/concomitant medication (including start and 
stop dates), dose, frequency, site of dosing (right eye, left eye, both eyes, non-ocular) and 
the reason why the prior/concomitant medication is being taken will be recorded in the 
source documents and in the Prior/Concomitant Medications (ConMeds) page of the 
eCRF.  
 Medications used for the surgical procedure will be recorded in the source documents and 
in the ConMeds page of the eCRF.  
 The ocular medications (mydriatics and topical analgesics) used to perform the dilated 
ophthalmoscopy and Goldmann applanation tonometry assessments will be recorded in 
the source documents only. 
Note: The information on prior/concomitant medications will be used to determine whether a 
subject is taking or has taken prohibited medications as outlined in Section 5.4.2. 
5.4.1 
Rescue Medication 
Any subjects who have evidence of persistent or worsening inflammation as described in Section 
9.4 may be rescued and placed on appropriate alternate therapy. The choice of rescue medication 
is at the Investigator's discretion.  Rescue medication should be entered into the eCRF with 
annotation indicating that the medication was used for rescue. 
Rescued subjects will be considered as treatment failures, and the need for rescue therapy will 
not be considered an adverse event (AE). Rescued subjects will stop study drug and should not

DESCRIPTION OF STUDY VISITS 
6.2.1 
Visit 1 - Screening 
The Screening visit should occur no more than 28 days and no less than one (1) day prior to 
surgery. After obtaining written informed consent and HIPAA authorization, site staff will 
perform the assessments as shown in the Schedule of Events (Table 1).  All ocular assessments 
must be performed on both eyes at the Screening visit, including the endothelial cell parameter 
assessments (endothelial cell density [cells/mm2], percent hexagonality and coefficient of 
variation) which will be performed in both eyes only in the subjects in the Endothelial Cell Sub-
study.  
Note: Information on contact lens use will be collected for subjects in the Endothelial Cell sub-
study. 
If surgery is not performed on the planned scheduled day such that screening procedures would 
fall outside of the 28 day screening window, site staff must contact the Study Medical Monitor to 
determine which, if any, of the screening procedures must be repeated. 
Subjects may be rescreened, if, in the opinion of the Investigator, the subject would qualify for 
the study if a procedure/assessment is repeated/redone (in this case, the subject keeps the same 
subject number). Note: If subject who has failed screening is rescreened at a later time, the 
subject will be assigned a new subject number.    
Subjects who sign the informed consent form (ICF) and have undergone study 
procedures/assessments, but do not meet eligibility criteria any time prior to randomization on 
POD1 will be considered as screen failures.  Limited information on screen failures will be 
transcribed to the eCRF. 
After the screening assessments and before surgery, the subject may have a pre-surgery medical 
assessment to determine whether the subject is a suitable candidate for surgery. At this time, the 
routine medication list prescribed by the cataract surgeon should be reviewed to rule out 
prohibited medications (Table 4, Section 5.4.2).   
6.2.2 
Day of Surgery (Day 0) 
Prior to surgery, the surgeon’s routine medication list should be reviewed to exclude prohibited 
medications (Table 4, Section 5.4.2).  Surgery should preferably be scheduled in the morning to 
accommodate BID dosing on POD1.  However, if surgery has to be scheduled in the afternoon, 
subjects should still instill two doses of study drug on POD1 at least 6 hours apart.

Formosa Pharmaceuticals, Inc. 
APP13007 
 
 
CONFIDENTIAL 
Page 61 of 95 
On Day 0, the surgeon will perform his/her routine cataract surgical procedure using 
phacoemulsification and implantation of a posterior chamber intraocular lens in the operated eye 
following the surgeon’s usual pre-operative, operative, and post-operative procedures (with the 
exception of avoiding use of prohibited medications).  Aqueous release procedures are not 
permitted. 
Following surgery, the following should be performed: 
 Give the subject instructions regarding routine post-surgical care and instructions 
regarding the use of concomitant medications and restricted medications during the study. 
 Record surgery parameters in the source documents and eCRF.  
o For subjects in the Main Study (not in the Endothelial Cell Sub-study) record: 
surgery time, phaecoemulsification information and the Surgeon evaluation of 
difficulty or complications.  
o For subjects in the Endothelial Cell sub-study record: Phacoemulsification 
machine make/model, Phacoemulsification time, Lens type, Cataract density 
grade and type, Location of wound, Coding of surgery as ‘standard’ or ‘complex’, 
Surgeon evaluation of difficulty or complications). 
 Record the medications routinely administered for cataract surgery in the source 
documents. These medications will be reported as being used for routine cataract surgery. 
 If a medication is administered due to an AE, the medication must be entered in the 
source documents, indicating that the medication was used to treat an AE.   
 If a non-prostaglandin medication is used to lower IOP, the medication must be entered 
in the source documents and in the ConMeds page of the eCRF. 
 AEs and ConMeds associated with an AE should only be recorded in the source 
document on Day 0 if they result in screen failure of the subject. If a subject is not a 
screen failure on Day 0, the AEs and ConMeds applicable to Day 0 should be recorded in 
the source documents when the subject returns for Visit 2 on POD1. 
 Only for subjects who are randomized, enter the medications routinely used for cataract 
surgery and concomitant medications in the ConMeds page of the eCRF and AEs in the 
AE page of the eCRF. 
 Schedule the subject to return to the clinic on the following day, ie., POD1, in the 
morning (if possible).

6.2.3 
Visit 2 - POD1 (Day of Randomization) 
Subjects will return to the clinic for the study visit on POD1 between 18 to 34 hours following 
conclusion of surgery on Day 0.  This visit should be scheduled in the morning, as much as 
possible, to allow for administration of two doses of study drug during the day on POD1 for 
randomized subjects.  However, if surgery is to be performed in the afternoon, subjects should 
still instill two doses of study drug on POD1 at least 6 hours apart. 
All assessments will be performed as shown in the Schedule of Events (Table 1). Ocular 
assessments will be performed only on the operated, study eye. 
The site will review eligibility criteria (Section 4.2 and Section 4.3) to determine if the subject 
qualifies for randomization. Women of child-bearing potential must have a negative urine 
pregnancy test pre-randomization.  If the subject meets all criteria, the subject will be 
randomized by site personnel using the EDC/IWRS system.  The site should follow the 
instructions provided in the Study Reference Manual)/eCRF Completion Guidelines to enter 
appropriate subject data into the eCRF and randomize the subject.  A study drug bottle number 
will be assigned to the subject based on the predetermined randomization by the EDC/IWRS 
system.  The designated site personnel should supervise the administration of the first dose of 
study drug by the subject in the clinic before dispensing the assigned study drug bottle along 
with written dosing instructions and diary to the subject. The second dose will be administered at 
home.  
A subject who fails to qualify for the study on POD1 will not be rescreened. 
Note that the use of IOP-lowering medications or aqueous release procedures are not allowed on 
POD1.  
Study drug dosing/administration procedures including handling bottle replacement, diary/dosing 
compliance and the list of treatments are presented in Section 5.1.2.  Subjects are reminded to 
bring the diary to each clinic visit in order for site staff to review dosing compliance. 
6.2.4 
Visit 3 (POD4 ± 1) and Visit 4 (POD8 ± 1) 
All assessments will be performed as shown in the Schedule of Events (Table 1).  
Ocular assessments will be performed only on the operated, study eye at Visit 3 (POD4) and 
Visit 4 (POD8). 
6.2.5 
Day of Subject Contact on POD14 
POD14 is the last day of dosing.  Site personnel will contact the subject on POD14 (no specific 
window) to remind the subject not to take study drug on POD15 and onward and to bring the

contact the subject using the subject’s preferred reliable method of communication, 
e.g., telephone call, cell phone text or email.  The site staff must make an effort to ensure that the 
subject receives and acknowledges the receipt of the message. Method of contact and whether or 
not the subject was reached is to be documented in the source document. 
Any AEs reported to the site during the POD14 contact must be recorded in the source 
documents and eCRF.  Further assessment of any reported AEs may require an Unscheduled 
Visit on POD14 if medically significant or they may be assessed, as appropriate, at Visit 5 
(POD15).

Early Termination/Withdrawal 
6.2.10.1 
Main Study 
Subjects who are terminated/withdrawn from the study early will have the Visit 6 (POD22) 
assessments and a urine pregnancy test performed (if applicable) at the time of termination, or as 
soon thereafter as possible.  At an Early Termination/Withdrawal visit the ocular assessments are 
to be performed on both eyes.  
6.2.10.2 
Endothelial Cell Sub-study  
Subjects who are terminated/withdrawn from the study before Visit 6 (POD22) will have the 
Visit 6 assessments and a urine pregnancy test performed (if applicable) at the time of 
termination, or as soon thereafter as possible.  At an Early Termination/Withdrawal Visit, the 
ocular assessments (except the endothelial cell parameters) are to be performed on both eyes. 
The endothelial cell parameters will be measured in the study eye only. 
Appendix A describes the Early Termination/Withdrawal procedures that may be implemented 
because of the COVID-19 pandemic. 
6.2.11 
Unscheduled Visits 
Any visits performed beyond those specified within the protocol must be documented in the 
Unscheduled Visit pages of the eCRF. Unscheduled visits may include, but are not limited to, 
reporting and/or follow-up of AEs/SAEs, changes in concomitant medications, follow-up of 
subjects receiving rescue or IOP-lowering medications or ophthalmic assessments as deemed 
appropriate by the Investigator.

Study Visit Schedule for Rescued Subjects 
Subjects who are rescued as discussed in Section 9.4 will discontinue study drug and receive 
rescue medication.   
The Investigator should make every effort to: 
 keep rescued subjects in the Main study until they complete the Visit 6 (POD22) 
assessments Table 1), 
 keep rescued subjects in the Endothelial Cell Sub-study until they complete the Visit 7 
(POD85) assessments (Table 1). 
6.3 
SUBJECT EARLY TERMINATION (WITHDRAWAL) 
Any subject who wishes to voluntarily discontinue study drug or withdraw from participation in 
the study for any reason is entitled to do so without obligation.  If a subject requests to 
discontinue the study drug, the subject will be withdrawn from the study as an Early Termination 
(see Section 6.2.10). 
The Investigator may discontinue any subject from study drug or from study participation, if 
deemed necessary at any time during the study for any reason including, but not limited to: 
 The investigator considers that the subject requires alternative medication that is 
incompatible with further continuation of the study drug or participation in the study.  
 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. 
 Any SAE, clinically significant AE, severe laboratory abnormality, intercurrent illness, or 
other medical condition that indicates to the Investigator that continued participation in 
the study is not in the best interest of the subject or that continued participation could 
affect study objectives. 
 Any woman who reports becoming pregnant while participating in the study.  
Information on the pregnancy and outcome will be requested by the Investigator.   
 Subject’s continued failure to comply with protocol requirements or study-related 
procedures after being instructed on the correct requirements or procedures by the 
Investigator or site personnel. 
 Termination of the study by the Sponsor, FDA, or other regulatory authority.

Best corrected Visual Acuity 
The assessment of best corrected visual acuity in the study (operated) eye will be performed as 
described in Section 7.3.1.2. 
7.3 
SAFETY ASSESSMENTS 
The safety assessments are applied to both eyes at Visit 1 (Screening) and Visit 6 (POD22) or 
Early Termination/Withdrawal or to the Study (operated) eye only at Visit 2 through Visit 5 
(Table 1 Schedule of Events). The safety assessments in Table 1 are not performed on the day of 
surgery.  
In the Endothelial Cell Sub-study, the corneal endothelial cell parameter measurements are 
performed in both the planned study eye and non-study eye at Visit 1 (Screening), and in the 
study eye only at Visit 6 (POD22)/Early Termination and Visit 7 (POD85). 
7.3.1 
List of Safety Assessments  
 AEs 
 ETDRS Assessment of Best Corrected Visual Acuity by Pinhole Method 
 Slit Lamp Biomicroscopy assessment of the following signs of inflammation: corneal 
edema, ciliary flush, bulbar conjunctival injection. The assessments in the non-study eye 
will include an assessment of the lens  
 IOP Measurement using Goldmann applanation tonometry 
 Dilated Ophthalmoscopy assessment of the vitreous, retina, macula, choroid, and optic 
nerve with cup/disc ratio, and an assessment of the presence and severity of a cataract if 
present in the non-study eye 
 Corneal Endothelial Cell Parameters: corneal endothelial cell density (cells/mm2), percent 
hexagonality and coefficient of variation (only in Endothelial Cell Sub-study) 
 
7.3.1.1 
Assessment of Adverse Events 
All AEs spontaneously reported by the subject or in response to an AE query from study 
personnel or revealed by observation, physical examination or other diagnostic procedures will 
be recorded in the source document and on the appropriate pages of the eCRF.  Any clinically 
relevant deterioration in a clinical finding is considered an AE and must be recorded. When

Page 69 of 95 
possible, signs and symptoms indicating a common underlying pathology should be noted as one 
(1) comprehensive event. Any pre-existing medical condition that worsens after administration 
of study drug will also be considered as an AE.  
Ocular complaints associated with and expected as a result of the surgery, that are not recorded 
as AEs in the eCRFs will be recorded in the source documents. An ocular complaint will be 
recorded in the eCRF as AE when the complaint is outside the normal limits for cataract surgery 
or is associated with clinical sequelae (i.e., adverse slit lamp examination finding).  
See Section 8.0 for information on how to record AEs and how to attribute relatedness of an AE 
to study procedures, cataract surgery or study drug. 
7.3.1.2 
ETDRS Best Corrected Visual Acuity Measurement by Pinhole Method 
Best corrected visual acuity measurement will be performed using the ETDRS eye chart at a 
preferred (but not required) distance of 4 meters. The testing should be conducted under 
standardized lighting conditions using the pinhole method for the study visits indicated in Table 
1.  Other testing distances may be used as long as it is consistent with the recommendations 
provided for the ETDRS chart being used and will be used consistently at each visit.   
The subject starts at the top of the chart and reads down until the subject reaches a row where the 
subject is unable to correctly read any letters on that line.   
The ETDRS Acuity Log Score was calculated as follows: 
1. Determine the last row where the subject can correctly identify at least one (1) letter in 
that row.  This is the Base Logarithm of the Minimum Angle of Resolution (logMAR) 
line. 
2. Determine the log score for the Base logMAR line. 
3. Add 0.02 (T=0.02) log units for every letter that is incorrectly identified up to and 
including the Base logMAR line. 
The results will be recorded in the source documentation and the eCRF. 
7.3.1.3 Slit Lamp Biomicroscopy 
In addition to the assessment of ACC and ACF (Section 7.2.2.1), the following safety parameters 
will be evaluated at Visits 1 through 6 as indicated in Table 1 using the following scales during 
the slit lamp examination:

IOP measurements will be performed utilizing Goldmann applanation tonometry according to 
the Investigator’s standard procedure. All pressures will be recorded in mmHg.  IOP assessments 
will be performed at Visits 1 (Screening) through Visit 6 (POD22) or Early 
Termination/Withdrawal as indicated in Table 1. 
7.3.3 
Dilated Ophthalmoscopy 
A dilated fundus examination will be performed according to the Investigator’s standard 
technique at the Visits indicated in Table 1.  The Investigator should evaluate the vitreous, retina, 
macula, choroid, and optic nerve with cup/disc ratio and will note normal/abnormal findings. If a 
cataract is present in the non-study eye, the Investigator will make an assessment of its location 
and severity as described below. 
The Investigator will determine whether or not abnormalities observed at Visit 1 (Screening) 
would exclude a subject from study participation.

If a subject had an abnormality in the study eye or non-study eye at Visit 1 (Screening), the 
Investigator should make an assessment whether there has been a change at Visit 6 (POD22) or 
at Early Termination/Withdrawal and record this in the source document and eCRF. It is 
recommended that the Investigator refer to the documentation at Visit 1 (Screening) when 
making the assessment of a change in status. 
Grading a Cataract in the Non-Study Eye 
For subjects with phakic lens in the non-study eye, when present, a cataract will be assessed 
(a) by location - Nuclear, Cortical, and Posterior Subcapsular, and (b) by severity (minimal, 
mild, moderate or severe). Appendix B provides a guidance that may be used to grade the 
severity of a nuclear, cortical or posterior subcapsular cataract in the non-study eye. 
If a subject had a cataract in the non-study eye at Visit 1 (Screening), the Investigator should 
make an assessment whether there has been a change in the size or composition of the cataract at 
Visit 6 (POD22) or at Early Termination/Withdrawal and record this in the source document and 
eCRF. It is recommended that (i) the cataract grading is performed by the same Investigator at 
Screening and Visit 6 (POD22) or at Early Termination/Withdrawal, and (ii) the Investigator 
refers to the documentation of the non-study eye at Visit 1 (Screening) when making the 
assessment of change in the lens status. 
7.3.4 
Endothelial Cell Density by Specular Microscopy 
Measurement of endothelial cell parameters will be performed at Visit 1 (Screening), Visit 6 
(POD22)/Early Termination and Visit 7 (POD85) in the subjects participating in the Endothelial 
Cell Sub-study. 
 
Non-contact specular microscopy will be conducted according to the instrument 
manufacturer’s specific instructions.  Note:  Do not enter Protected Health Information 
when entering data on the subject information screen.   
 
A centralized reading center 
 
 
 
 will evaluate the site equipment, train technicians and will conduct the 
reading and analysis of images.  
 
Images will be exported to the central reading center for evaluation according to the 
process defined by

 
Specular microscopic images will be obtained from the center of the cornea at Visit 1 
(Screening), Visit 6 (POD22)/Early Termination and Visit 7 (POD85).  The center of the 
cornea will be defined as the region above the pupil.  
 
Acceptable images should be collected from the central region of the cornea.  
 
Endothelial cell density (cells/mm2), percent hexagonality and the coefficient of variation 
will be assessed from specular microscope images.

8.0 
ADVERSE EVENTS 
8.1 
DEFINITION OF ADVERSE EVENTS (AEs) 
Adverse event means any untoward medical occurrence in a subject or clinical investigation 
subject administered a pharmaceutical product and which does not necessarily have a causal 
relationship with this treatment (21CFR312.32 (a); ICF E6 Section 1).  An AE can therefore be 
any unfavorable sign and unintended sign (including an abnormal laboratory finding), symptom, 
or disease temporally associated with the use of a medicinal (investigational) product, whether or 
not related to the medicinal (investigational) product. 
In addition to the considerations in Sections 8.2 to 8.4, AEs will be reported in the source 
document from the time of signature of the informed consent form as indicated in Section 8.1.1 
and Section 8.1.2.   
8.1.1 
Subjects who are Randomized 
 An AE related to cataract surgery will be recorded in the Surgical AE log table in the 
source documents and in the eCRF. 
 AEs occurring prior to study drug administration will be recorded in the source 
documents only. 
 AEs occurring from the start of study drug administration will be reported in the source 
documents and eCRF. 
 Rescued subjects are considered to be treatment failures, and being rescued itself is not 
considered to be an AE. 

Clinical Study Protocol:  CPN-302 (Version 1.2, Amendment 1) 
Formosa Pharmaceuticals, Inc. 
APP13007 
 
 
CONFIDENTIAL 
Page 73 of 95 
 Adverse events occurring in rescued subjects will be reported in the source documents 
and eCRF.  
 An IOP > 30 mmHg after Randomization will be reported as an AE in the source 
documents and eCRF. 
 An IOP ≥ 21 mmHg AND an IOP increase > 10 mmHg from pre-dose baseline will be 
reported as an AE in the source documents and eCRF. 
 Serious Adverse Events will be collected from the time of signature of the informed 
consent form and reported in the source documents and eCRF. 
The term “severe” is used to describe the intensity of an AE; the event itself could be of 
relatively minor clinical significance (e.g., ‘severe’ headache).  This is not the same as “serious”.  
Seriousness of AEs is based on the outcome of an AE and usually associated with events that 
pose a threat to a subject’s life or functioning. 
A Treatment Emergent Adverse Event (TEAE) will be defined as any AE that occurs from the 
start of study drug administration through Visit 6 (POD22).   
8.1.2 
Subjects who are Not Eligible for Randomization (Screen Failures) 
 AEs will be reported in the source documents only 
 Serious Adverse Events will be collected from the time of signature of the informed 
consent form and reported in the source documents and eCRF 
8.2 
DEFINITION OF SERIOUS ADVERSE EVENTS (SAEs) 
An AE is considered "serious" if the event results in any of the following outcomes:   
• 
death,  
• 
a life-threatening adverse event (i.e. the subject is, in the view of the investigator, at 
immediate risk of death from the AE as it occurs),  
• 
subject hospitalization or prolongation of existing hospitalization,  
• 
a persistent or significant incapacity or substantial disruption of the ability to conduct 
normal life functions, or  
• 
a congenital anomaly/birth defect.  
Important medical events that may not result in death, but may be life-threatening, or require 
hospitalization may be considered serious when, based upon appropriate medical judgment, they

may jeopardize the participant and may require medical or surgical intervention to prevent one of 
the outcomes listed in this definition.  Examples of such medical events include allergic 
bronchospasm requiring intensive treatment in an emergency room or at home, blood dyscrasias 
or convulsions that do not result in subject hospitalization, or the development of drug 
dependency or drug abuse. 
A serious and unexpected suspected adverse reaction (SUSAR) is defined as a serious adverse 
reaction or suspected serious adverse reaction that is not listed in the APP13007 Investigator’s 
Brochure or is not listed at the specificity or severity that has been observed, or that is mentioned 
in the APP13007 Investigator’s Brochure as occurring with a class of drugs or as anticipated 
from the pharmacological properties of the study drug, but is not specifically mentioned as 
occurring with the particular drug under investigation (See Section 8.7.2). 
8.3 
CLASSIFICATION OF AN ADVERSE EVENT 
8.3.1 
Severity of Event 
Assessment of severity of an AE will be rated according to the definitions below in Table 5 and 
the worst grade documented. 
Table 5: 
Definitions of AE Severity 
Mild 
Events require minimal or no treatment and do not interfere with 
the participant’s daily activities. 
Moderate 
Events result in a low level of inconvenience or concern with the 
therapeutic measures. Moderate events may cause some 
interference with functioning. 
Severe 
Events interrupt a participant’s usual daily activity and may require 
systemic drug therapy or other treatment. Severe events are usually 
potentially life-threatening or incapacitating.  Of note, the term 
“severe” does not necessarily equate to “serious”. 
 
8.3.2 
Relationship to Ocular Surgical Procedure or Study Drug 
Determination of the relationship (if any) between the AE and the study drug will be made using 
the guidelines presented in Table 6 and Table 7. 

Clinical Study Protocol:  CPN-302 (Version 1.2, Amendment 1)

Page 75 of 95 
Table 6: 
Guidelines for Determining the Relationship (if any) between an Adverse 
Event and the Ocular Surgical Procedure 
Related 
This causal relationship is assigned if the AE starts at a reasonable time during or after 
the surgical intervention and could reasonably be explained by the known 
characteristics of the surgical intervention. 
Not Related 
This causal relationship is assigned when the time association or the subject’s clinical 
state is such that the surgical intervention was not likely to have had an association 
with the observed AE. 
 
Table 7: 
Guidelines for Determining the Relationship (if any) between an Adverse 
Event and the Study Drug 
Definite 
This causal relationship is assigned if the AE starts a reasonable time after the 
administration of study drug, stops/improves when the study drug is stopped, and could 
reasonably be explained by known characteristics of the study drug. 
Probable 
This causal relationship is assigned when the AE starts a reasonable time after the 
administration of study drug, stops/improves when the study drug is stopped, and could 
not be reasonably explained by known characteristics of the subject’s clinical state. 
Possible 
This causal relationship is assigned when the AE starts a reasonable time after the 
administration of study drug, but could be produced by the subject’s clinical state or 
other modes of therapy administered to the subject. 
Not Related 
This causal relationship is assigned when the time association or the subject’s clinical 
state is such that the study drug was not likely to have had an association with the 
observed AE. 
 
The attributability (relatedness) of an AE to the surgical procedure or to the study drug will be 
reported in the source documents and in the eCRF as described in Section 8.1.1 and Section 
8.1.2.   
8.3.3 
Expectedness 
An AE or a suspected adverse reaction (SAR) is considered “unexpected” if it is not listed in the 
APP13007 Investigator’s Brochure or is not listed at the specificity or severity that has been

8.3.4 
Action Taken with Study drug 
The action to be taken in response to an AE will be to either discontinue or continue study drug.   
Subjects will be permitted to restart study drug if there is a temporary interruption of study drug 
dosing not more than 1 day due to an AE.   
Decrease in the dosing frequency or dosing duration of the study drug is not allowed in this 
study. 
8.3.5 
Adverse Event Outcome 
If an AE occurs, the Investigator will institute support and/or treatment as deemed appropriate. 
The outcome of the adverse event will be categorized as follows: 
• 
Resolved 
• 
Resolved with sequelae 
• 
Ongoing 
• 
Death 
• 
Unknown 
The Investigator should make every attempt to follow SAEs to resolution. 
8.4 
ADVERSE EVENT FOLLOW-UP 
If a non-serious AE is unresolved at the time of the subject’s final study visit, the subject will 
still be released from the study, but 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 all SAEs to resolution.   
8.5 
OVERDOSE/UNDER-DOSE FOR ASSESSMENT OF COMPLIANCE 
8.5.1 
Overdose 
Dosing compliance will be assessed via a daily dosing diary completed by the subject and 
reviewed by the designated site personnel.   
The following will be classified as an overdose event and a protocol deviation (further explained 
in Note below): 
 Subject instills > 2 doses of study drug (each dose = 1 drop) into the study eye on 2 
consecutive days.

Note:  (i) As described in Section 5.1.2, if the subject misses the conjunctival cul-de-sac when 
dosing the study drug, the subject should use a tissue to wipe away the study drug around the eye 
and then instill a second drop into the conjunctival cul-de-sac.  This will not be considered a 
protocol deviation.  However, if the subject administers a third drop or more into the 
conjunctival sac, no matter if the previous drops were missed, this will be considered to be a 
protocol deviation; (ii) the importance of the protocol deviation (major/minor) will be 
determined by the amount of dosing over that specified in the protocol. 
8.5.2 
Under-dose 
Under-dosing will not be reported as a protocol deviation until the subject has missed both of the 
doses on 2 or more consecutive days. 
The importance of the protocol deviation (major/minor) will be determined by the amount of 
dosing under that specified in the protocol. 
8.6 
PREGNANCIES 
All female subjects enrolled into the study must be of non-childbearing potential or have a 
negative urine pregnancy test on POD1 prior to randomization (and agree to abstain from sexual 
activity or use a highly effective method of contraception).  Therefore, no pregnancies should 
occur.  A urine pregnancy test will also be performed at Visit 5 (POD15) or Early 
Termination/Withdrawal visit prior to Visit 5 (POD15). If there is an unexpected pregnancy, it 
will be handled on a case-by-case basis by discussing with the Study Medical Monitor and then 
the Sponsor Medical Monitor. 
Additionally, the Investigator should report the information to the Sponsor in a Pregnancy-
specific CRF as per the procedures to be followed for an SAE. Although a pregnancy itself is not 
an SAE, it has potentially serious consequences in subjects exposed to investigational drugs that 
can result in an SAE. 
The pregnancy and follow-up of the pregnancy must be reported on the appropriate pregnancy 
CRF/Pregnancy Reporting Form. The expected date of delivery or expected date of the end of 
the pregnancy, last menstruation, estimated fertility date, pregnancy result and neonatal data etc., 
should be included in this information. 
The investigator will follow the medical status of the mother, as well as the fetus, as if the 
pregnancy is an SAE and will report the outcome to the Sponsor. Follow-up visits must continue 
until the end of the pregnancy, even if that lasts beyond the end of the study. 
When the outcome of the pregnancy falls under the criteria for SAEs (spontaneous abortion, 
induced abortion, stillbirth, death of newborn, congenital anomaly [including anomaly in a

miscarried fetus]), the investigator should respond in accordance with the report procedure for 
SAEs. Additional information regarding the outcomes of a pregnancy which are categorized as 
an SAE is mentioned below: 
• 
"Spontaneous abortion" includes abortion and missed abortion. 
• 
Death of an infant within 1 month after birth should be reported as an SAE regardless of its 
relationship with the study drug. 
• 
If an infant dies more than 1 month after the birth, it should be reported if a relationship 
between the death and intrauterine exposure to the study drug is judged as "possible" by the 
investigator. 
• 
In the case of a delivery of a living newborn, the "normality" of the infant is evaluated at 
birth. 
• 
"Normality" of a miscarried fetus is evaluated by visual examination unless test results 
which indicate a congenital anomaly are obtained prior to miscarriage. 
8.7 
SERIOUS ADVERSE EVENT REPORTING 
8.7.1 
Reporting Requirements 
It is the responsibility of the Investigators or their designees to report any event of this nature to 
the Sponsor or a designee within 24 hours of the event being brought to the Investigators’ or 
their staffs’ attention.  It is also the responsibility of the Investigator to report all SAEs reported 
at their site to the IRB, as required.  The Investigator should make every attempt to follow all 
SAEs to resolution.   
All SAEs have to be reported on a separate SAE Report Form, whether or not considered 
causally related to the study drug, or to the study procedure(s). All SAEs will be recorded in the 
eCRF. SAEs will be recorded from the time the informed consent form is signed.  
The Sponsor will be responsible for reporting all reportable SAEs to regulatory authorities and 
the Investigator is responsible for reporting all reportable SAEs to the IRB (see NOTE below) in 
accordance with IRB guidelines and FDA regulations. As soon as the Investigator is aware of a 
potential SAE he/she should contact 
 
 and in any case no later than 24 hours after 
the knowledge of such a case. At the time of initial reporting the Investigator must provide as a 
minimum requirement, subject number, birth date, description of the SAE and a preliminary 
assessment of causality.  
For fatal or life-threatening adverse events where important or relevant information is missing, 
active follow-up is undertaken immediately. Investigators or other site personnel inform the 
Study Medical Monitor, the Sponsor, and the CRO for Study Management and Monitoring of 
any follow-up information on a previously reported SAE immediately but no later than within 24

hours of when the Investigator becomes aware of it. The Study Medical Monitor or Sponsor 
Medical Monitor will advise the Investigator/study site personnel how to proceed. The 
Investigator will immediately follow-up events deemed by the Sponsor to be Serious and 
Unexpected Suspected Adverse Reactions (SUSARs) or possible SUSAR events needing 
immediate follow-up in order to meet the 15 calendar day reporting requirements. 
The SAE reporting procedures are detailed in the study-specific Safety Management Plan. This 
plan is an agreement between the Sponsor, the CRO for Study Management and Monitoring and 
 
NOTE: If an unexpected SAE occurs at any one site that is determined to be related, probably 
related or possibly related to study drug, all study sites will be notified by the Sponsor via the 
CRO for Study Management and Monitoring and each Investigator will report it to the IRB.   
8.7.2 
Reporting of Serious and Unexpected Suspected Adverse Reactions (SUSARS) 
A serious suspected adverse reaction is any serious adverse event for which there is a reasonable 
possibility that the study drug caused the adverse event. A serious adverse reaction is considered 
"unexpected" (serious and unexpected suspected adverse reaction; SUSAR) if it is not listed in 
the APP13007 Investigator’s Brochure or is not listed at the specificity or severity that has been 
observed.  
SUSARs with an outcome of death or are life threatening must be reported to the relevant 
Regulatory Authorities within 7 calendar days, all other SUSARs must be submitted within 15 
calendar days.  The SUSAR reporting procedures are detailed in the study Safety Management 
Plan. This plan is an agreement between the Sponsor, the CRO for Study Management and 
Monitoring and Synergy Research Pharmacovigilance.  
NOTE: The Sponsor will notify the U.S. Food and Drug Administration (FDA) and all 
participating site Investigators of any SUSARs (via the CRO for Study Management and 
Monitoring) on an expedited basis and in accordance with applicable regulations.  In addition the 
sponsor is responsible for informing all Investigators in all ongoing studies involving the study 
drug about all SUSARs.  
Medical and administrative data related to Individual Case Safety Reports which qualify for 
expedited and periodic reporting, should be provided in compliance with U.S. FDA Code of 
Federal Regulations (CFR) 21, 312.32. 
It is the responsibility of the Investigator to promptly notify the IRB and other appropriate 
institutional regulatory bodies of all unexpected serious adverse reactions involving risk to 
human subjects as per their applicable requirements.

SAFETY MANAGEMENT 
9.1 
STOPPING CRITERIA  
9.1.1 
Individual Subject 
9.1.1.1 
Lack of Efficacy (See Section 9.4) 
The Investigator should consider whether to stop the study drug because of lack of efficacy and 
rescue the subject with alternative therapy (see Section 9.4).   
Rescued subjects shall continue in the study and be assessed at each subsequent scheduled visit 
until Visit 6 (POD22) (Main Study) or Visit 7 (Endothelial Cell Sub-study). The study drug will 
be stopped as indicated in Section 9.4.2. 
9.1.1.2 
Elevated Intraocular Pressure (See Section 9.5) 
The Investigator should consider whether to stop the study drug because of an elevation of IOP.  
The study drug may or may not be continued as indicated in Section 9.5.2. 
9.1.1.3 
Deleterious Effects of the Study Drug 
The investigator may stop the study drug and withdraw the subject if in their opinion the study 
drug is having a deleterious effect on the subject’s health or wellbeing.  The investigator should 
make an effort to follow up the subject until the deleterious effect is resolved. 
9.1.1.4 
Lack of Compliance 
The investigator may stop the study drug and withdraw the subject if in their opinion the subject 
is not complying with study procedures, including, but not limited to, dosing of the study drug. 
9.1.2 
Study Termination  
 The study can be stopped at any time if deemed necessary by the Sponsor Medical 
Monitor, in consultation with the Study Medical Monitor, due to safety concerns.  
Safety will be monitored on an ongoing basis via periodic masked review of AEs and 
other safety endpoints.   
O If it is observed that visual acuity worsens by 2 lines (Base LogMAR change 
of 0.2 using ETDRS chart) at Visit 6 (POD22) in the treated study eye as 
compared to Visit 2 (POD1), in 6 consecutive subjects, no further doses of 
study drug will be administered to any subjects in the study until a

comprehensive evaluation can be performed, and, if possible, a cause is 
identified.   
 Safety assessments will be performed throughout the course of the study. The 
APP13007 Investigator’s Brochure, Section 1.4.1 and the Risk Mitigation plan in 
Table 2 provide guidance for the Investigator on potential anticipated AEs that may 
occur. Any potential important safety issues that arise will be reviewed by the Study 
Medical Monitor, in consultation with the Sponsor Medical Monitor, to identify the 
appropriate course of action.   
 If the Sponsor elects to terminate the study for any reason, the Investigator will be 
responsible for notification of the IRB and will withhold further dosing of study drug. 
9.2 
DOSE MODIFICATION 
No dose modification is permitted.   
All instances of missed doses must be recorded.     
Note:  Study drug bottle will be replaced as soon as possible if a bottle is lost or otherwise 
compromised before Visit 5 (POD15) (see Section 5.1.2). This may require an unscheduled visit.   
9.3 
DOSING INTERRUPTIONS 
Investigator is not allowed to modify the dosing regimen due to an AE or any other 
circumstance, but the Investigator has the option of stopping study drug after consultation with 
the Study Medical Monitor, if feasible.   
Subjects will be permitted to restart study drug if there is a temporary dosing interruption of 
study drug of not more than 1 day due to an AE. 
9.4 
RESCUE MANAGEMENT 
9.4.1 
Criteria for Starting Rescue Medication 
Any subject not responding to the study drug because of lack of efficacy at any time after 
randomization at Visit 2 (POD1) may be rescued and placed on an appropriate alternative 
therapy determined by the Investigator.  
In general, at any visit, a subject with worsening inflammation or showing no improvement in 
degree of inflammation compared with the previous visit is eligible for rescue therapy at the 

Clinical Study Protocol:  CPN-302 (Version 1.2, Amendment 1)

Page 82 of 95 
discretion of the Investigator. However, the following guidance is provided to Investigators for 
consistency in the way subjects are rescued:  
1. Subjects who, on examination of the anterior chamber, have one or more of the following 
quantitative criteria should be rescued and discontinued from study drug dosing and 
placed on rescue mediation: 
o An increase of ACC count by > 15 cells from the Visit 2 (POD1) pre-dose 
baseline. 
o A ≥ 2 grade increase in ACF grade from the Visit 2 (POD1) pre-dose baseline.  
2. Subjects who have the following qualitative criteria may be rescued. If the subject is 
rescued, the study drug should be discontinued and rescue mediation started: 
o Subjects who have pain and/or photophobia that does not improve, even when 
there is an improvement in ACC count and/or ACF grade, may be rescued at 
the discretion of the investigator. 
o Subjects who have pain and/or photophobia that worsens may be rescued at 
the discretion of the investigator. 
Initiation of rescue medication is at the discretion of the Investigator. However, it is 
recommended that the Investigator uses the above guidance to determine when to rescue a 
subject. If the quantitative ACC count or ACF grade criteria are not met, the Investigator should 
discuss the qualitative reason(s) for rescue with the Study Medical Monitor for consistency 
across the study.    
9.4.2 
Management 
Investigators will use clinical judgment to determine when to rescue a subject using the guidance 
provided in Section 9.4.1 and the appropriate rescue medication to use. Rescued subjects will 
stop study drug and will continue in the study, and will be assessed at each subsequent visit, if 
possible, through completion of the Visit 6 (POD22) assessments (if participating in the Main 
study) or Visit 7 (POD85) assessments (if participating in the Endothelial Cell Sub-study) (Table 
1) or until the Investigator has deemed the subject is stable and can be released from the study. 
If a subject needs to be rescued at Visit 5 (POD15), the Visit 5 (POD15) assessments (Table 1) 
should be completed before the subject is administered rescue medication. 
Rescued subjects will be considered treatment failures, and the need for rescue medication will 
not be considered as an AE.

Page 83 of 95 
An AE occurring at the time of rescue will be recorded in the eCRF and will be followed by the 
Investigator to stabilization or resolution of the AE or the end of the study (whichever comes 
last).   
If a subject is rescued, this event will be recorded in the eCRF (not as an AE). Medications used 
for rescue will be recorded in the ConMeds section of the eCRF, indicating that they were used 
for rescue.   
9.5 
MANAGEMENT OF INCREASED IOP 
9.5.1 
Criteria for Starting IOP-Lowering Medication 
Investigators should use the following criteria to determine whether to start IOP-lowering 
medication:  
 After randomization, an IOP > 30 mmHg in the study eye 
 After randomization, an IOP ≥ 21 mmHg AND an increase of > 10 mmHg from the Visit 
2 (POD1) pre-dose baseline in the study eye (both of these criteria must be met) 
Initiation of IOP-lowering medication is at the discretion of the Investigator even if neither of the 
above criteria are met, however, it is recommended that the Investigator uses these criteria to 
determine when to consider a subject for IOP-lowering medication.     
9.5.2 
Management 
Investigator will use clinical judgment to determine the appropriate IOP-lowering medication to 
use and when to withdraw study drug and procedures, in consultation with the Study Medical 
Monitor.  
It is important to note that prostaglandin-based IOP lowering medications are prohibited in this 
study. 
 After randomization and start of study drug, if a subject has an IOP > 30 mmHg the 
Investigator may commence non-prostaglandin-based IOP-lowering medication while 
continuing the study drug, with appropriate follow-up at the next planned visit or at an 
unscheduled visit. The subject may require assessment at an unscheduled visit at the 
investigator’s discretion. 
o If the IOP is < 30 mmHg at the next visit, the subject may continue on study drug.   
o If at the next visit, the IOP remains > 30 mmHg while on IOP-lowering medication, 
then the study drug may be discontinued and alternative IOP-lowering medication

may be started, after consultation with the Study Medical Monitor. The subject 
should continue in the study and complete the assessments indicated in Table 1 
through Visit 6 (POD22) (Main Study) or Visit 7 (POD85) (Endothelial Cell Sub-
study).  The Study Medical Monitor should discuss the persistent elevation of IOP 
with the Sponsor Medical Monitor.   
 After randomization and start of study drug, an IOP of ≥ 21 mmHg AND an increase > 
10 mmHg from the Visit 2 (POD1)/pre-dose baseline (both criteria must be met) is 
considered clinically significant and the Investigator should consider starting non-
prostaglandin-based IOP-lowering medication while continuing the study drug, with 
appropriate follow-up at the next planned visit or at an unscheduled visit.   
o If the IOP reduction is satisfactory at the next visit, the subject may continue on 
study drug. 
o If the IOP reduction of IOP is not satisfactory at the next visit, then the study drug 
may be discontinued and alternative IOP-lowering medication may be started, after 
consultation with the Study Medical Monitor. The subject should continue in the 
study and complete the assessments indicated in Table 1 through Visit 6 (POD22) 
(Main Study) or Visit 7 (POD85) (Endothelial Cell Sub-study).  The Study Medical 
Monitor should discuss the persistent elevation of IOP with the Sponsor Medical 
Monitor.     
Medications used for treating increased IOP will be recorded in the Concomitant Medications 
section of the eCRF, noting that they were used to reduce IOP.

STATISTICAL CONSIDERATIONS 
10.1 
STATISTICAL ANALYTICAL PLAN 
The Statistical Analysis Plan (SAP) will describe the details of all efficacy and safety analyses 
and will be finalized prior to database lock. 
10.2 
ANALYSIS POPULATIONS 
The analysis populations are defined as follows: 
 Intent-to-Treat (ITT) Population: All subjects who are randomized to study drug.   
Following the ITT principle, subjects will be analyzed according to the treatment they are 
assigned to at randomization.

Page 85 of 95 
 Per-protocol (PP) Population: All subjects in the ITT population who (i) received at last 1 
dose of study drug, (ii) do not have major protocol deviations that would impact the 
evaluation of efficacy and (iii) have at least 80% overall dosing compliance.  
 Safety Population: All randomized subjects who receive at least one dose of study drug.   
10.3 
STATISTICAL METHODS 
10.3.1 
General Approach 
All analysis variables will be summarized descriptively by treatment group. Summary statistics 
for continuous measures will include mean, standard deviation, median, and range. Categorical 
measures will be summarized by the number and percent of subjects. 
10.3.2 
Analysis of Efficacy 
All efficacy analyses and summaries will be based on assessments in the study eye for each 
subject. 
Subjects who are rescued at any time prior to Visit 5 (POD15) will be considered as treatment 
failures for the primary efficacy endpoints and the relevant secondary efficacy endpoints. For 
subjects who discontinue from the study prior to Visit 5 (POD15), the last observation carried 
forward (LOCF) approach will be used to impute missing data.  
For continuous secondary efficacy endpoints, the LOCF approach will also be used to impute the 
data at visits after subjects are rescued. 
The ACC count will be graded as shown below:  
Grade 
0 
1 
2

10.3.2.1 
Analyses of Primary Efficacy Endpoints: 
The primary efficacy analyses to compare APP13007 against placebo will be conducted on the 
ITT population using the Pearson Chi-square statistic. Fixed sequence testing will be employed 
to maintain the 2-sided alpha = 0.05. The primary analyses will first test the difference between 
treatments in the proportion of subjects with ACC count = 0 (Grade = 0) at POD8 (Visit 4) 
maintained through POD15 (Visit 5). If the test is statistically significant at the 2-sided 
alpha = 0.05 level in favor of APP13007, the difference between treatments in the proportion of

Page 86 of 95 
subjects with Ocular Pain grade = 0 at POD4 (Visit 3) maintained through POD15 (Visit 5) will 
be tested at the two-sided alpha = 0.05 level.  
To confirm the robustness of primary analysis results, sensitivity analyses, including using 
observed data from all subjects, will be performed. The detailed sensitivity analyses will be 
described in the SAP.   
10.3.2.2 
Analyses of Secondary Efficacy Endpoints: 
Mean change-from-baseline in ACC Grade, ocular Pain Grade, ACF Grade and visual acuity at 
PODs 4, 8 and 15 will be analyzed using an analysis of covariance (ANCOVA). The ANCOVA 
model will include treatment as a fixed effect and baseline as a covariate. The rest of secondary 
efficacy endpoints will be analyzed using the same method described for the primary efficacy 
endpoints.   
10.3.3 
Analysis of Safety 
Analysis of safety data will be performed for all subjects in the Safety Population.  
Adverse events will be coded using Medical Dictionary for Regulatory Activities (MedDRA) 
and classified by system organ class and preferred terms. Adverse events will be summarized by 
total number of TEAEs, number of subjects reporting TEAEs, ocular TEAEs (affecting the study 
eye and/or the non-study eye and/or both eyes, when appropriate), non-ocular TEAEs, SAEs, 
serious and unexpected suspected adverse reactions (SUSARs), discontinuing study drug due to 
an AE, by relationship to study drug and/or ocular surgical procedure, and by severity.  
The IOP data for both eyes will be summarized at screening, Visit 6 (POD22)/Early Termination 
(Withdrawal) visit and change from screening. The observed IOP data and change-from-baseline 
(POD1) for the study eye will be summarized at each post-surgery visit. 
The data for slit lamp biomicroscopy examination endpoints will be summarized at each visit. 
The summary of change-from-baseline at each post-surgery visit will be presented for the study 
eye.  
Dilated indirect ophthalmoscopic examination findings for the study and non-study eye will be 
summarized at screening and Visit 6 (POD22)/Early Termination (Withdrawal).  
Visual Acuity data will be summarized at each visit. The summary of change-from-baseline at 
each post-surgery visit will be presented for the study eye.

Analysis of Corneal Endothelial Cell Parameters 
The corneal endothelial cell parameter data (corneal endothelial cell density [cell/mm2], percent 
hexagonality and coefficient of variation) from the Endothelial Cell Sub-study will be 
summarized at each assessment visit. The mean change from baseline (Visit 1/Screening) for 
each treatment group and the mean difference with 95% confidence interval between treatment 
groups will be calculated at Visit 7 (POD85) for the three parameters, as appropriate. The 
percent change from baseline at Visit 7 (POD85) for corneal endothelial cell density will also be 
summarized.  
10.3.5 
Interim Analysis 
No interim analyses are planned for this study. 
10.4 
SAMPLE SIZE ESTIMATION 
The assumption for the sample size determination was estimated using the Package Inserts of 
Durezol®, Lotemax® and Inveltys® and results from the APP13007 Phase 2 study (CPN-201).  
The sample size for ACC count primary efficacy endpoint is based on the assumption of 26% of 
subjects in the APP13007 group with ACC Count = 0 at POD8 and maintained through POD15 
and 12% of subjects in the matching vehicle placebo group. The two-group chi-square test, with 
a two-sided significance level of 5% and 92% power, requires 175 subjects per treatment group 
to detect the difference between APP13007 and placebo. 
The same sample size using the assumption of 57% of subjects with Ocular Pain Grade = 0 at 
POD4 and maintained through POD15 in APP13007 group and 38% of subjects in placebo group 
will provide 95% power to detect the treatment difference. 
With an estimated 5% dropout rate, this study will randomize approximately 185 subjects per 
treatment group for a total of approximately 370 subjects.   
In the Endothelial Cell Sub-study, a sample size of 80 subjects per treatment group is considered 
adequate to evaluate the corneal endothelial cell parameters between treatment groups. With a 
10% dropout rate, the Sub-study will enroll approximately 88 subjects per treatment group for a 
total of approximately 176 subjects to be randomized for the Endothelial Cell Sub-study. 
10.5 
LEVEL OF SIGNIFICANCE 
Unless otherwise specified, all statistical tests will be two-sided and the statistical significance 
will be tested at the 5% level.  
The primary efficacy endpoints will be evaluated using the fixed sequence testing described in 
Section 10.3.2.1.

PROCEDURE FOR ACCOUNTING FOR MISSING, UNUSED, OR SPURIOUS 
DATA 
If more than 5% of data points are missing at POD15 in any treatment group, a tipping point 
analysis will be performed to assess the sensitivity of the primary efficacy results to the 
distribution of the allocation of treatment success and failure to the missing data points. Other 
missing data imputations will be detailed in the SAP.  
10.7 
PROCEDURE FOR REPORTING DEVIATIONS FROM THE STATISTICAL 
PLAN 
Any deviations from the SAP will be described and a justification given in the final clinical study 
report. 
10.8 
SUBJECTS TO BE INCLUDED IN THE ANALYSIS 
All efficacy analyses will be performed using the ITT population. In addition, the analysis of the 
primary efficacy endpoints will be performed using the PP population as a supportive analysis. 
AEs and other safety endpoints will be analyzed using the Safety Population.

submitted to the IRB.  Written IRB approval must adequately identify the protocol and informed 
consent form.  Copies of all approved materials, all correspondence with the IRB, and written 
approval from the IRB must be made available to the Sponsor (or designated Study Monitor). 
Any modification of study procedures or amendments to the protocol must be approved by the 
IRB and submitted to FDA prior to implementation.  In the event that a modification or 
amendment is considered by the Investigator to be immediately necessary to ensure subject 
safety, the Investigator will promptly notify his or her IRB, the Study Medical Monitor, and the 
CRO for Study Management and Monitoring who will then notify the Sponsor. 
Investigators will report all SAEs reported at their site to their IRB, as appropriate.   
11.1.4 
Informed Consent Process 
Written informed consent will be obtained from each participant prior to any study-related 
procedures being performed (prior to or on the Screening visit).  A copy of the signed and dated 
informed consent document will be given to each subject.  The original signed and dated 
informed consent document must be maintained in the study files at the investigative site and be 
available for the CRO for Study Management and Monitoring and the Sponsor or designee(s) to 
review.   
Each informed consent will contain Investigator contact information with a telephone number the 
subject or the subject’s authorized representative can call 24 hours a day and 7 days a week if 
they have medical concerns. 
11.1.5 
Subject Confidentiality and Disclosure 
Study personnel will have access to a subject’s protected health information (PHI). This 
information may be obtained by the Sponsor, which includes any persons or companies that are 
working with, working for, or owned by the Sponsor.  PHI may be given to the U.S. FDA 
Department of Health and Human Services agencies, other governmental agencies in the U.S., 
governmental agencies in other countries, and governmental agencies to which certain diseases 
(reportable diseases) must be reported. 
11.2 
MONITORING AND AUDITING STUDY DOCUMENTATION 
The Investigator(s)/institution(s)  will permit trial-related monitoring, audits, IRB review, and 
regulatory inspection(s) by providing direct access to source data and documents (such as tests 
performed as a requirement for participation in the study and other medical records) to the Study 
Monitor or the Sponsor or its designee.

11.2.1 
Clinical Monitoring 
Before an investigational site can enter a subject into the study, a representative of the Sponsor 
or its designee such as the CRO for Study Management and Monitoring 
 
 and its Study Monitor will perform pre-study site evaluation at each of the 
investigational study sites in person or remotely to: 
 Determine the adequacy of the facilities 
 Discuss with the Investigator(s) and other personnel their responsibilities about protocol 
adherence, and the responsibilities of the Sponsor or its designated Study Monitor and 
representatives.  This will be documented in a Clinical Study Agreement between the 
Sponsor (Formosa Pharmaceuticals, Inc.) and the Investigator. 
 Confirm qualified staff are trained on the protocol, study processes and systems. 
 Confirm all supplies and study product are onsite and stored accordingly. 
 Collect any outstanding essential documents. 
During the study, a monitor from the Sponsor or its designated CRO for Study Management and 
Monitoring 
 and its Study Monitor or representative will have 
regular contacts with the investigational site, for the following: 
 Provide information and support to the Investigator(s). 
 Confirm that facilities remain acceptable. 
 Confirm that the investigational team is adhering to the protocol, that data are being 
accurately recorded in the eCRFs, and that study treatment accountability checks are being 
performed. 
 Perform source data verification.  This includes a comparison of the data in the eCRFs with 
the subject’s medical records at the investigational site, and other records relevant to the 
study.  This will require direct access to all original records for each subject (e.g. clinic charts 
or electronic records). 
 Record and report any protocol deviations not previously sent to the Sponsor and the IRB. 
 Confirm the site has adequate supplies and study drugs. 
 Confirm AEs and SAEs have been properly documented in eCRFs and confirm that any and 
all SAEs have been forwarded to the Sponsor via the CRO for Study Management and 
Monitoring and those SAEs that met criteria for reporting have been forwarded to the IRB. 
The Study Monitor and other representatives at the CRO for Study Management and Monitoring 
will be available between visits if the Investigator(s) or other staff needs information or advice.

11.2.2 
Auditing of Sites and Study Documentation 
Quality control and quality assurance may be performed before, during, and after the study by 
the Sponsor or Sponsor’s designee, such as the CRO for Study Management and Monitoring and 
its Study Monitors.  Regulatory authorities in certain countries reserve the right to audit study 
sites following submission of data in regulatory applications. The Investigator may be given due 
notice of any intended audit by a regulatory body.  By signing this protocol and the FDA Form 
1572, the Investigator acknowledges that these inspection procedures may take place and agrees 
to provide access to the required subject records and other study documentation.  Furthermore, 
the Investigator agrees to inform the Sponsor via the CRO for Study Management and 
Monitoring immediately of any known or suspected inspection by authorities.  If the Investigator 
does not comply with the protocol, GCP, or regulations, the Sponsor reserves the right to 
disqualify the Investigator and/or site from the current or future protocols. 
11.3 
DATA HANDLING AND RECORD KEEPING 
All procedures for the handling and analysis of data will be conducted using GCP and will meet 
ICH guidelines and US FDA regulations for the handling and analysis of data for clinical trials. 
11.3.1 
Data Collection and Management Responsibilities 
After data have been entered into the study database, a system of computerized data validation 
checks will be implemented and applied to the database.  Query reports pertaining to data 
omissions and discrepancies will be forwarded to the Investigator and Study Monitor(s) from the 
CRO for Study Management and Monitoring for resolution.  The study database will be updated 
in accordance with the resolved query reports.  All changes to the study database will be 
documented. 
11.3.2 
Study Records Retention 
The study center will retain all records related to the study in accordance with local and ICH 
GCP guidelines. 
11.4 
PROTOCOL DEVIATIONS 
Monitoring will be conducted to verify compliance.  Instances of minor, major and critical 
deviations that occur at investigative sites will be documented and communicated to the Sponsor 
and documented at the investigative site and recorded in the eCRF.  Any noted protocol 
deviations meeting the IRB reporting requirements will reported to the IRB.

CONTINGENCY PLANS RELATED TO THE COVID-19 
PANDEMIC 
 
In March 2020 the FDA issued the Guidance: “Conduct of Clinical Trials of Medical Products 
during COVID-19 Pandemic”.   
 
Based on the stated goal in this FDA Guidance, the following plans may be implemented: 
 
1. 
When a clinical site plans to or has to close operations and visits cannot be 
scheduled per protocol:  
 If possible, schedule an Early Termination/Withdrawal visit before the clinical site closes. 
o Ask subject to stop the study drug, if before Visit 5 (POD15). 
o Collected study drug and dosing diary. 
o Conduct the Visit 6 (POD22) assessments. 
 A Protocol Deviation is documented as “Early Termination/Withdrawal visit performed 
because the study site closed for operations prior to completion of the study visits due to 
COVID-19 infection-control requirements”. 
 
2. 
When a subject cannot or does not want to return for an in-person visit:  
 The clinical site coordinator contacts the subject by telephone (or alternative method of 
communication) and asks the subject to stop the study drug, if before Visit 5 (POD15), and 
collects AE and concomitant medication information.  
o The available information is entered in the Early Termination/Withdrawal section of the 
eCRF.  
o If before Visit 5 (POD15), the study coordinator requests the subject to send the study 
drug bottle and dosing diary to the study coordinator at the clinical site. 
 The Investigator withdraws the subject from the study and considers alternative methods of 
assessing the subject. 
 A Protocol Deviation is documented as “Subject withdrawn early (Early Termination) and 
the assessments for Visits X, Y and Z were not performed because the subject could not or 
did not want to return for an in-person visit due to COVID-19 infection-control 
requirements”.
