Overall Study Design: 
Structure: 
Multi-center, randomized, double-masked, Vehicle-controlled, parallel-group, safety 
and efficacy study 
Duration: 
Approximately 3-4 weeks (screening and 3 study visits) 
Controls: 
Vehicle  
Treatment plan: 
Visit 1 (Screening, Day -14 to -1): Qualified subjects will receive 1 drop of Vehicle 
instilled in each eye, followed by preliminary efficacy assessments to identify 
Vehicle responders at 15 minutes post-vehicle instillation.  
Visit 2 (Day 1): Baseline assessments. Subjects who meet all inclusion and none of 
the exclusion criteria and qualify as Vehicle non-responders, will be randomized 1:1 
to one of the following treatment arms: 
• 
CSF-1 (0.4% pilocarpine hydrochloride ophthalmic solution) 
• 
Vehicle 
Pre-treatment measurements taken at this visit are considered as baseline.  
At the Day 1 clinic visit, study personnel will instill Dose 1 of study drug at 8:30 AM 
± 30 minutes in each eye. Efficacy and safety assessments will be conducted for 2 
hours following Dose 1. Dose 2 will be instilled by study personnel at 10:30 AM ± 
30 minutes in each eye. Efficacy and safety assessments will be conducted for 4 
hours following Dose 2.  
All subjects will be instructed to dose twice daily (BID) with a single drop for 
approximately 1 week in each eye. The first daily dose should occur in the morning, 
with the second dose following 2 hours later (+1 hour). Subjects will be instructed 
not to dose at home on clinic visit days. 
Visit 3 (Day 8): Study personnel will instill Dose 1 of study drug at 8:30 AM ± 30 
minutes in each eye. Efficacy and safety assessments will be conducted for 2 hours 
following Dose 1. Dose 2 will be instilled by study personnel at 10:30 AM ± 30 
minutes in each eye. Efficacy and safety assessments will be conducted for 2 hours 
following Dose 2.  
All subjects will be instructed to dose twice daily (BID) with a single drop  for 
approximately 1 week in each eye. The first daily dose should occur in the morning 
with the second dose following 3 hours later (+1 hour). Subjects will be instructed 
not to dose at home on clinic visit days.  
Visit 4 (Day 15): Study personnel will instill Dose 1 of study drug at 8:30 AM ± 30 
minutes in each eye. Efficacy and safety assessments will be conducted up to 3 hours 
following Dose 1. Dose 2 will be instilled by study personnel at 11:30 AM ± 30

minutes in each eye. Efficacy and safety assessments will be conducted for 5 hours 
following Dose 2. 
Measures Taken to 
Reduce Bias: 
Randomization will be used to avoid bias in the assignment of subjects to treatment 
and to enhance the validity of statistical comparisons across treatment groups.  
Double-masked treatment will be used to reduce the potential of bias during data 
collection and the evaluation of clinical endpoints. 
Study Population Characteristics: 
Number of Subjects: 
Approximately 300 subjects (2 arms; 150 subjects per treatment arm) will be 
enrolled. 
Condition/Disease:

Efficacy Endpoints 
 
Primary Endpoints: 
Percentage of subjects with a ≥ 3-line (15-letter) gain, from baseline, in best distance-
corrected visual acuity (BDCVA) at 40 cm (Precision Vision chart) and no loss in 
best distance corrected visual acuity ≥ 5 letters (ETDRS chart at 4m) in the study eye 
at Visit 3, following Dose 1, 1 hour post-treatment

The 40 cm Precision Vision chart uses the same letter and line spacing as the ETDRS 
chart, only calibrated in size for testing at 40 cm. Similar to the 4m chart, the 
Precision Vision 40 cm chart is placed in light box creating retro illumination for 
testing. 
Secondary Endpoints: 
Percentage of subjects with a ≥ 3-line (15-letter) gain, from baseline, in BDCVA at 
40 cm (Precision Vision chart) and no loss in best distance corrected VA ≥ 5 letters 
(ETDRS chart at 4m) in the study eye at the following Visits, Doses and time points: 
 
Visit 3 (Day 8) 
Dose 1

General Statistical Methods and Types of Analyses 
Analysis Sets: 
• 
Full Analysis Set – The full analysis set (FAS) will include all randomized subjects who have received 
at least one dose of the study drug. Subjects in the FAS will be analyzed as randomized. 
• 
Per Protocol Set – The per-protocol (PP) set will include subjects in the FAS who do not have significant 
protocol deviations that affect the primary endpoint analysis. Protocol deviations will be assessed prior 
to database lock and unmasking. Subjects in the PP set will be analyzed as treated. 
• 
Safety Set – The safety set will include all subjects who have received at least one dose of the study 
drug. Subjects in the safety population will be analyzed as treated. 
Unit of Analysis: 
The study eye will be used for all monocular analyses. The fellow eye will inherently be included in all binocular 
analyses. Both eyes will be displayed and analyzed for all ophthalmic safety variables. 
The study eye will be defined by the study Investigator as the eye that meets all enrollment criteria. If both eyes 
meet all enrollment criteria, then the eye with the worse Visit 2 pre-treatment/baseline BDCVA at 40 cm 
(Precision Vision chart) will be the study eye. If both eyes have the same BDCVA at 40 cm, the right eye will be 
the study eye. 
General Considerations: 
In general, quantitative/continuous data will be summarized using descriptive statistics (n, mean, standard 
deviation (SD), median, minimum, and maximum). Qualitative/categorical data will be summarized using 
frequencies and percentages. Statistical testing, unless otherwise indicated, will be performed at a 2-sided 0.05 
significance level. 
For all variables, baseline is defined as the pre-randomization measurement taken at Visit 2 (Day 1), prior to 
administration of study drug. Change from baseline will be calculated as follow-up measure minus baseline 
measure. 
Hypothesis: 
The primary efficacy hypothesis is: 
H01: The difference between study eyes treated with CSF-1 and study eyes treated with Vehicle, in the percentage 
of study eyes with a ≥ 3-line (15-letter) improvement from baseline in BDCVA at 40 cm (Precision Vision chart) 
without a loss in best distance corrected VA of ≥ 5 letters (ETDRS at 4m) at Visit 3 (Day 8), 1 hour post-Dose 1 
= 0. 
H11: The difference between study eyes treated with CSF-1 and study eyes treated with Vehicle, in the percentage 
of study eyes with a ≥ 3-line (15-letter) improvement from baseline in BDCVA at 40 cm (Precision Vision chart) 
without a loss in best distance corrected VA of ≥ 5 letters (ETDRS at 4m) at Visit 3 (Day 8), 1 hour post-Dose 1 
≠ 0. 
The study will be considered a success if the null hypothesis, H01, is rejected at a 2-sided alpha = 0.05 in favor of 
CSF-1 in the alternative hypothesis, H11, tested as delineated in the primary efficacy analysis section, and the 
following secondary efficacy hypotheses will each be tested as stated under adjustments for multiplicity. 
The secondary efficacy hypotheses are:

= 0. 
H12: The difference between study eyes treated with CSF-1 and study eyes treated with Vehicle, in the percentage 
of study eyes with a ≥ 3-line (15-letter) improvement from baseline in BDCVA at 40 cm (Precision Vision chart) 
without a loss in best distance corrected VA of ≥ 5 letters (ETDRS at 4m) at Visit 3 (Day 8), 2 hours post-Dose 1

If the primary null hypothesis, H01, is rejected at a 2-sided alpha = 0.05 in favor of CSF-1 in the alternative 
hypothesis, H11, tested as delineated in the primary efficacy analysis section, then the study will be considered a 
success and the following secondary hypotheses will be tested in hierarchical order, each at a 2-sided alpha = 
0.05, where inference will be made on each null hypothesis only if the prior null hypotheses are rejected in favor 
of CSF-1

40 cm (Precision Vision chart) and no loss of best distance corrected VA ≥5 letters (ETDRS at 4m), 1-hour post 
each dose on Visit 3 (Day 8) assuming a response rate of 42.5% in CSF-1 and 17.5% in Vehicle using a Pearson 
chi-squared test with a 2-sided significance level of 0.05. 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
Accounting for approximately a 5% discontinuation rate, approximately 150 subjects per arm (approximately 300 
total) will be randomized. 
Estimates were obtained from the Phase 2b study (18-150-0006) Intent-to-Treat (ITT) population response for 
pilocarpine 0.4% vs. diclofenac (control), additionally imputing missing data as failures.  
At least approximately 30% of subjects will have light (i.e., blue, green, gray, and hazel) iris, and at least 
approximately 30% will have a brown iris. The actual percentages will vary based on enrollment. 
Primary Efficacy Analysis: 
The primary efficacy endpoint in this study is the percentage of subjects with a ≥ 3-line (15-letter) gain, from 
baseline, in best distance-corrected visual acuity (BDCVA) at 40 cm (Precision Vision chart) and no loss in best 
distance corrected visual acuity ≥ 5 letters (ETDRS chart) at Visit 3, 1 hour following Dose 1 in the study eye. 
The primary efficacy analysis will be conducted in the FAS with intercurrent events handled in the following 
manners:  
1) Discontinuation of study drug and non-optimal compliance will be ignored [treatment policy strategy]. 
2) Withdrawal due to lack of efficacy or adverse events: missing data will be singly imputed as failure 
[hypothetical strategy]. 
3) Missing data without withdrawal or withdrawal due to reasons other than lack of efficacy or adverse 
events: missing data will be imputed employing Multiple Imputation (MI) using randomized treatment-
based Markov Chain Monte Carlo (MCMC) methodology [hypothetical strategy]. 
No subject data will be excluded from the FAS due to protocol violations/deviations. The FAS will be used for 
the primary efficacy analyses. Note that multiple imputations of missing values will be completed for the 
continuous measures (BDCVA at 40 cm and best distance corrected VA at 4m), then the response variable will be 
determined therefrom. 
Sensitivity analyses on the primary efficacy variable will be performed using the FAS with all missing data 
imputed as failures, the FAS with observed data, and PP set with observed data. Additional sensitivity analyses 
such as control-based pattern mixture model MIs and tipping point may be performed and will be specified in the 
Statistical Analysis Plan (SAP). 
Descriptive statistics will be presented by treatment group. Testing of the percentage of subjects with at least a 3-
line (15-letter) improvement from baseline in BDCVA at 40 cm without a loss of ≥ 5 letters in best distance 
corrected VA at 4m will be completed separately for the 1 hour and 2 hour time points using a generalized linear 
mixed model with a binomial distribution including fixed effects of baseline BDCVA at 40 cm as a covariate, 
daily dose (Dose 1 and Dose 2), treatment, and the interaction of dose with treatment and random effect of 
subject to account for the correlation within a subject between daily doses. The dose-by-treatment interaction 
term will be used to check if there is differential treatment effect between Dose 1 and Dose 2. If the dose-by-

treatment interaction term is significant (p < 0.10), then the interaction term will remain in the model and testing 
of the treatment effect will be completed within the model separately following Dose 1 and following Dose 2. If 
the dose-by-treatment interaction term is not significant (p ≥ 0.10), then the interaction term will be removed 
from the model and testing of treatment effect will be completed within the model pooled over dose.  
The adjusted odds ratios and marginal proportions and difference in proportions along with corresponding two-
sided 95% Confidence Intervals (CIs) and p-values will be presented. 
Treatment comparisons will also be made separately for each time point and dose using logistic regression model 
including fixed effects of baseline BDCVA at 40 cm as a covariate and treatment, Pearson’s chi-squared test or 
Fisher’s exact test if any of the cell counts are less than five as a sensitivity analysis to the primary model above.  
Secondary Efficacy Analysis:  
For the secondary efficacy endpoints of BDCVA at 40 cm, the percentage of subjects who achieve a ≥ 3-line (15-
letters) improvement from baseline without a loss of ≥ 5 letters in best distance corrected VA at 4m for each 
Visit, time point and daily dose (Dose 1 and Dose 2) will be summarized and analyzed using the same imputation 
as the primary efficacy endpoint. The same modeling strategy will be used as detailed in the primary efficacy 
analysis for any time point that is measured after both doses within the visit

study drug, will be summarized by treatment group using frequency and percent for each System Organ Class 
(SOC) and Preferred Term (PT) within each SOC. Similar summaries will also be presented for serious TEAEs, 
TEAEs leading to death, TEAEs leading to study drug discontinuation, TEAEs related to IP and TEAEs by 
severity. When reporting the incidence of AEs, a subject will only be counted once if they ever experience an 
event within the SOC and ever experience the individual PT within the SOC. 
Actual results and changes from baseline results in monocular and binocular BCVA at 4m and Low- Luminance 
BCVA, slit-lamp biomicroscopy, conjunctival redness grading, IP drop comfort, IOP, and dilated fundus 
examination will be summarized descriptively at each visit by treatment group. 
Full details of the safety analyses will be specified in the formal SAP.

INTRODUCTION 
Most individuals will develop symptoms of presbyopia by age 50 (Truscott 2009). Worldwide, 
there were 1.8 billion people globally with presbyopia in 2015, with a prevalence of 
approximately 25%, which is growing as the world population is aging. Approximately 45% of 
these cases (~826 million) had near visual impairment (VI) because of lack of or inadequate 
vision correction (Fricke, Tahhan et al. 2018). The primary symptom of this condition is a 
progressive blurring of vision when performing near tasks such as reading, sewing, working at a 
computer, and using a tablet or cellular phone. Other symptoms include headaches and visual 
fatigue, which impair one’s quality of life (Truscott 2009).  
The underlying cause of presbyopia is an inability to change optical power (accommodation) 
(Donders 1864). Accommodation is facilitated by the contraction of the ciliary muscle fibers, 
which change the shape and location of the crystalline lens of the eye. In response to near vision, 
the crystalline lens becomes thicker and more rounded in response to the actions of the ciliary 
muscle fibers (Garner and Yap 1997, Croft, Glasser et al. 2001, Glasser 2006). As an individual 
ages, the lens becomes stiffer and less amenable to changing shape in response to ciliary Muscle 
activity and this culminates in the symptoms of presbyopia. 
Pupil size is determined by the dimensions of sphincter and dilator muscle spindles of the iris. 
The pupil becomes smaller in conjunction to accommodation. This reduction in the size of the 
pupil (termed miosis) improves the resolution of the retinal image by preventing peripheral light 
rays from reaching the retina. A relatively small pupil offers increased depth of field in a way 
similar to that achieved by reducing the aperture of a camera, leading to better visual acuity (VA) 
of close objects. 
Current presbyopia treatment strategies include corrective lenses with single vision or 
bifocal/multifocal lenses, corneal refractive surgery, corneal inlay procedures, and intra-ocular 
lens surgery. Monovision correction improves the near vision of one eye (through the use of 
lenses, contacts, or surgery) while allowing the other eye to be used for distance vision. This 
approach has had variable results and may cause disturbances in depth-perception (Fernandez, 
Schwarz et al. 2013). Lastly, surgical correction of vision in presbyopia includes conductive 
keratoplasty, laser-assisted in-situ keratomileusis (LASIK), laser-assisted epithelial 
keratomileusis (LASEK), photorefractive keratectomy (PRK), corneal inlays, and 
accommodative or multifocal intraocular lenses (IOLs). The results of these procedures are 
variable, at times inconsistent, and contraindicated in some patient groups (Moussa, Jehangir et 
al. 2017). The inconsistencies regarding the success of some of these procedures of presbyopia 
treatment indicate a need for alternative strategies. 
The treatment proposed here repurposes a muscarinic receptor agonist to stimulate effects on iris 
and ciliary contractility via stimulation of muscarinic acetylcholine receptor M3. Pilocarpine, a 
muscarinic agonist, has been successful in treating cases of dilated pupil following ocular 
surgery (Patel, Jenkins et al. 2002) and a broad spectrum of systemic conditions including 
botulism (Monaco, Freddi et al. 1998), leprosy (Lana-Peixoto, Campos et al. 2014), sarcoidosis 
(Bowie and Givre 2003), and Ross syndrome (Weller, Wilhelm et al. 1992, Chemmanam, 
Pandian et al. 2007). 
CSF-1 was initially developed as a combination of a Non-Steroidal Anti-Inflammatory Drug 
(NSAID), diclofenac, with pilocarpine to reduce a potential inflammatory response associated 
with pilocarpine.

The safety and efficacy of CSF-1 (the initial combination and current formulation) is well 
established based on several previous clinical studies; an investigator-led feasibility study and 
two Phase 2a studies demonstrated favorable safety and preliminary efficacy. 
A Phase 2b multicenter, randomized, double-masked, parallel groups, clinical study was 
conducted to measure the contribution of each active ingredient to the efficacy and safety of 
CSF-1. Subjects were assigned to one of three treatment arms; diclofenac sodium alone 
(0.006%), pilocarpine HCl (0.2% and 0.4%) combined with diclofenac sodium (0.006%), and 
pilocarpine HCl alone (0.2% and 0.4%, the latter being the current formulation). Results from 
this study showed that diclofenac did not significantly improve tolerability, safety or efficacy of 
pilocarpine in subjects with presbyopia. Furthermore, the percentage of subjects in the CSF-1 
(pilocarpine HCl 0.4%/diclofenac sodium 0.006%) and pilocarpine HCl (0.4%) alone groups 
with ≥ 3-line improvement in monocular BCVA at 40 cm from baseline, 1-hour post-treatment at 
Visit 4 was statistically significant (p-value=0.0015 for CSF-1 group and p-value= 0.0002 for 
pilocarpine HCl group) compared to the diclofenac group, demonstrating success for the primary 
efficacy endpoint in the CSF-1 (pilocarpine HCl 0.4%/diclofenac sodium 0.006%) and 
pilocarpine HCl (0.4%) alone groups. The study thus indicated that 0.4% pilocarpine HCl as a 
single active ingredient was responsible for the temporary correction of presbyopia and that 
diclofenac is not needed in the formulation. For this reason, the Sponsor decided to continue the 
clinical development of CSF-1 with pilocarpine HCl 0.4% alone and to drop diclofenac from the 
clinical formulation 
In addition, a post-hoc analysis was conducted with the additional criteria of no loss of ≥ 5 letters 
in distance VA to the primary endpoint. Results of this post-hoc analysis showed that 22 (43.1%) 
of the subjects in the CSF-1 group, and 21 (42.9%) of the subjects in the pilocarpine HCl group 
had a ≥3 line (15-letter) gain in BCVA at 40 cm and no loss of distance VA of ≥ 5 letters, 1-hour 
post-treatment at Visit 4 (Day 15) from baseline. This post-hoc analysis further solidifies the 
results from the Phase 2b study and suggests that not only is CSF-1 effective for the temporary 
correction of presbyopia (evidenced by a ≥ 3 line gain in BCVA 1-hour post-administration at 
Day 15 compared to baseline) but also that the benefit in BCVA at 40 cm remains after 
considering that no worsening of distance BCVA of ≥5 letters or more occurs. These results 
support the conduct of a multicenter, randomized, double masked, vehicle controlled, 2-arm, 
Phase 3 efficacy and safety study with the current formulation of CSF-1 (pilocarpine 0.4%) 
versus Vehicle, as well as define the choice of the primary end-point in the present study.

OVERALL STUDY DESIGN 
This is a 4-visit multi-center, randomized, double-masked, parallel-group study evaluating the 
safety and efficacy of CSF-1 compared with Vehicle in approximately 300 subjects with 
presbyopia. The study design is summarized in Figure 1. 
Visit 1 (Screening, Day -14 to -1): Qualified subjects will receive 1 drop of Vehicle instilled in 
each eye, followed by preliminary efficacy assessments to identify Vehicle responders at 15 
minutes post-vehicle instillation.  
Visit 2 (Day 1): Baseline assessments. Subjects who meet all inclusion and none of the exclusion 
criteria and qualify as Vehicle non-responders, will be randomized 1:1 to one of the following 
treatment arms: 
• CSF-1 (0.4% pilocarpine hydrochloride ophthalmic solution) 
• Vehicle 
Pre-treatment measurements taken at this visit are considered as baseline. 
At the Day 1 clinic visit, study personnel will instill Dose 1 of study drug at 8:30 AM ± 30 
minutes in each eye. Efficacy and safety assessments will be conducted for 2 hours following 
Dose 1. Dose 2 will be instilled by study personnel at 10:30 AM ± 30 minutes in each eye. 
Efficacy and safety assessments will be conducted for 4 hours following Dose 2. 
All subjects will be instructed to dose twice daily (BID) with a single drop for approximately 1 
week in each eye. The first daily dose should occur in the morning, with the second dose 
following 2 hours later (+1 hour). Subjects will be instructed not to dose at home on clinic visit 
days. 
Visit 3 (Day 8): Study personnel will instill Dose 1 of study drug at 8:30 AM ± 30 minutes in 
each eye. Efficacy and safety assessments will be conducted for 2 hours following Dose 1. Dose 
2 will be instilled by study personnel at 10:30 AM ± 30 minutes in each eye. Efficacy and safety 
assessments will be conducted for 2 hours following Dose 2.

STUDY PARAMETERS 
6.1 
Efficacy Endpoints 
Primary Efficacy Endpoints 
Percentage of subjects with a ≥ 3-line (15-letter) gain, from baseline, in BDCVA at 40 cm 
(Precision Vision chart) and no loss in BDCVA ≥ 5 letters (ETDRS chart at 4m) in the study eye 
at Visit 3, following Dose 1, 1 hour post-treatment 
The BDCVA at 40 cm is measured using an ‘ETDRS-like’ chart from Precision Vision. The 40 
cm Precision Vision chart uses the same letter and line spacing as the ETDRS chart, only 
calibrated in size for testing at 40 cm. Similar to the 4m chart, the Precision Vision 40 cm chart 
is placed in light box, creating retro illumination for testing. 
Secondary Efficacy Endpoints 
Percentage of subjects with a ≥ 3-line (15-letter) gain, from baseline, in BDCVA at 40 cm 
(Precision Vision chart) and no loss in BDCVA ≥ 5 letters (ETDRS chart at 4m) in the study eye

STUDY MATERIALS 
7.1 
Study Treatments 
Investigational Product 
The investigational product (IP) is CSF-1, a sterile topical eye drop solution. The formulation 
developed by Orasis Pharmaceuticals Ltd. is a preservative-free eye drop, containing the active 
ingredient pilocarpine hydrochloride 0.4%, with the addition of standard pharmacopoeial 
excipients used in sterile ophthalmic solutions. 
The vehicle (CSF-1 placebo) is a topical eye drop solution containing the same ingredients as in 
CSF-1 except for the active ingredient. 
Both IP and Vehicle are packaged in a single-dose transparent low-density polyethylene (LDPE) 
vials, enclosed within a pouch. Each pouch includes five vials. Kits will be dispensed to subjects 
at Visit 2 and Visit 3 with 1 week of at-home dosing in each kit. CSF-1 will be evaluated for 
comparison to Vehicle. 
Instructions for Use and Administration 
All study treatments are topical ophthalmic solutions that should be administered bilaterally.  
Following Visit 2, all subjects will be instructed to dose twice daily (BID) with a single drop in 
each eye for approximately 1 week. The first daily dose should occur in the morning, with the 
second dose following 2 hours later (+1 hour). Subjects will be instructed not to dose at home on 
clinic visit days. 
Following Visit 3, all subjects will be instructed to dose twice daily (BID) with a single drop in 
each eye for approximately 1 week. The first daily dose should occur in the morning with the 
second dose following 3 hours later (+1 hour). Subjects will be instructed not to dose at home on 
clinic visit days. 
Subject Instructions 
After randomization at Visit 2, subjects will receive study drug and a paper dosing diary. Once 
dispensed to the subject, the study drug must be stored in a refrigerator or cooler with ice pack. 
Study drug is packaged as a single dose unit. Subjects will remove one pouch from a single study 
drug kit and remove one vial from the strip. The remaining vials will be returned to the opened 
pouch and placed back into the refrigerator. Each subject will instill one drop of study drug to 
each eye and keep aside the used vial to be returned to the site at next visit for compliance check. 
An open vial should not be re-used. Subjects will be instructed to save and return all used and 
unused study drug and to bring their kits to each study visit. Following Visit 2, subjects will be 
instructed to dose bilaterally BID (with 2 hours (+1 hour) between doses) and record doses in 
their diary until Visit 3. Subjects should not dose at home on day of Visit 3. At Visit 3, subjects 
will receive their doses at the visit by study personnel after the required pre-treatment 
assessments and the current study drug will be collected. After subjects receive their study drug 
and dosing diary, subjects will be instructed to dose bilaterally BID (with 3 hours (+1 hour) 
between doses) and record doses in their diary until Visit 4. Subjects should not dose at home on 
day of Visit 4. At Visit 4, subjects will receive their doses at the visit by study personnel after the 
required pre-treatment assessments and their study drug will be collected. Subjects will exit the 
study after all assessments are complete at Visit 4.

STUDY METHODS AND PROCEDURES 
8.1 
Subject Entry Procedures 
Overview 
Subjects as defined by the criteria in Section 5.1 and Section 5.2 will be considered for entry into 
this study. 
Informed Consent 
Prior to a subject’s participation in the trial (i.e., changes in a subject’s medical treatment and/or 
study-related procedures), the study will be discussed with each subject, and subjects wishing to 
participate must give written informed consent using an Informed Consent Form (ICF) and other 
written documentation in accordance with local privacy requirements (where applicable). 
Additional information can be found in Section 11.1.1. 
Washout Intervals 
• Use any of the following prohibited systemic medications during the timeframe noted 
below: 
o The day of the study visit or within 12 hours prior to a study visit (chronic, daily 
use is not allowed):  
▪ nonsteroidal anti-inflammatory drugs (NSAIDs) (e.g., Advil®, Motrin®)  
▪ narcotic (opiate class) pain medication (e.g., codeine, OxyContin®, 
Vicodin®, Tramadol®) 
o Two (2) weeks (14 days) prior to Visit 1 or for the duration of the study:  
▪ bladder medication (e.g., Urecholine®, bethanechol) 
▪ antipsychotics 
▪ antidepressants 
▪ attention-deficit/hyperactivity disorder (ADHD) medications 
▪ alpha-blockers (e.g., tamsulosin [Flomax®], Jayln®, Uroxatral®, Rapaflo®) 
▪ anticholinergics (e.g., atropine, belladonna, benztropine, dicyclomine, 
donepezil, hyoscyamine, propantheline, scopolamine, trihexphenidyl) 
▪ muscarinic receptor agonists or cholinergic agonists (e.g., Salagen®, 
Evoxac®) other than the study drug 
▪ over-the-counter (OTC) or prescription antihistamines or decongestants 
▪ any ophthalmic medications (other than artificial tears or lubricant eye 
ointment [see exclusion 8 and 9 above]) 
▪ any other medication affecting the pupil or accommodation 
▪ recreational drug use (e.g., marijuana, methadone, heroin, cocaine) 
Procedures for Final Study Entry 
Subjects must satisfy all inclusion and none of the exclusion criteria in order to be entered into 
the study. 
Pregnancy 
Females must have a negative urine pregnancy test at Visit 1, if female of childbearing potential 
(those who have experienced menarche and who are not surgically sterilized [bilateral tubal 
ligation, hysterectomy, or bilateral oophorectomy] or post-menopausal [12 months after last 

Orasis Pharmaceuticals

menses]) and must use adequate birth control throughout the study period. Adequate birth control 
is defined as hormonal – oral, implantable, injectable, or transdermal contraceptives; mechanical 
– spermicide in conjunction with a barrier such as condom or diaphragm; IUD; or surgical 
sterilization of partner. For non-sexually active females, abstinence may be regarded as an 
adequate method of birth control. 
In the event a female has a positive urine pregnancy test at Visit 4, the subject will be withdrawn 
from the study and the investigator will notify 
 and the sponsor within 24 hours of knowledge 
of the positive pregnancy test. 
Methods for Assignment to Treatment Groups 
Each subject who signs an ICF will be assigned a subject number. Subject numbers will be 
assigned in sequential order beginning with 001. Once a subject meets all qualification criteria at 
Visit 2, he/she will be randomized in a 1:1 ratio via an Interactive Response Technology (IRT) 
system to one of the following treatment groups: 1: CSF-1 (pilocarpine hydrochloride 0.4% 
ophthalmic solution), 2: Vehicle, and stratified by iris color (brown versus light [i.e., blue, green, 
gray, and hazel]) and by baseline manifest refraction spherical equivalent (-4.5 D to <-0.5 D, -0.5 
D to +0.75 D, and >+0.75 D to +2.0 D); randomization will not be stratified by site.  
At least approximately 30% of subjects will have light (i.e., blue, green, gray, and hazel) iris and 
at least approximately 30% will have a brown iris. The actual percentages will vary based on 
enrollment. 
Randomization will be used to avoid bias in the assignment of subjects to treatment, to increase 
the likelihood that known and unknown subject attributes (e.g., iris color and baseline 
characteristics) are evenly balanced across treatment groups, and to enhance the validity of 
statistical comparisons across treatment groups. Double-masked treatment will be used to reduce 
the potential of bias during data collection and the evaluation of clinical endpoints.  
8.2 
Concurrent Therapies and Medical History 
The use of any concurrent medication, prescription, or OTC taken within 30 days of Visit 1, is to 
be recorded on the subjects’ source document and corresponding electronic Case Report Form 
(eCRF) along with the reason the medication was taken. 
All significant current and prior ocular medical and surgical history are to be recorded on the 
subjects’ source document and corresponding eCRF. All current and prior significant general 
medical and surgical history is to be recorded on the subject’s source document and 
corresponding eCRF. 
Concurrent enrollment in another investigational drug or medical device study is not permitted. 
Prohibited Medications/Treatments 
Washout intervals as described in Section 8.1.2 should be followed for all prohibited 
medications. Soft contact lenses must be removed at least 7 days prior to study Visit 1 and during 
the study, and RGP contact lenses must be removed at least 14 days prior to study Visit 1 and 
during the study.

ADVERSE EVENTS 
9.1 
Adverse Event 
An adverse event (AE) is defined as any untoward medical occurrence associated with the use of 
an IP in humans, whether it is considered IP-related or not. An AE can be any unfavorable and 
unintended sign (e.g., an abnormal laboratory finding), symptom, or disease temporally 
associated with the use of an IP, without any judgment about causality. An AE can arise from 
any use of the IP (e.g., off-label use, use in combination with another drug or medical device) 
and from any route of administration, formulation, or dose, including an overdose.  
All AEs spontaneously reported by the subject and/or in response to an open question from study 
personnel or revealed by observation, physical examination, or other diagnostic procedures will 
be recorded in the subject’s source document and eCRF. Any clinically relevant deterioration in 
clinical finding is considered an AE and must be recorded. When possible, signs and symptoms 
indicating a common underlying pathology should be noted as one comprehensive event. 
Documentation regarding the AE should be made as to the nature, date of onset, end date, 
severity, relationship to IP, expectedness, action(s) taken, seriousness, and outcome of any sign 
or symptom observed by the physician or reported by the patient upon indirect questioning. 
All AEs will be collected from the time a subject signs the ICF through the subjects’ study exit 
visit. 
Severity 
The severity of an AE is defined as a qualitative assessment of the degree of intensity of an AE 
as determined by the investigator or reported to him/her by the patient/subject. The assessment of 
severity is made irrespective of relationship to IP or seriousness of the event and should be 
evaluated according to the following scale: 
• Mild: Event is noticeable to the subject but is easily tolerated and does not interfere with 
the subject’s daily activities. 
• Moderate: Event is bothersome, possibly requiring additional therapy, and may interfere 
with the subject’s daily activities. 
• Severe: Event is intolerable, necessitates additional therapy or alteration of therapy, and 
interferes with the subject’s daily activities. 
Relationship to Investigational Product 
The relationship of each AE to the IP should be determined by the investigator using these 
explanations: 
• Suspected: A reasonable possibility exists that the IP caused the AE. 
• Not Suspected: A reasonable possibility does not exist that the IP caused the AE. 
“Suspected adverse reaction” means any AE for which there is a reasonable possibility that the 
IP caused the AE. “Reasonable possibility” means there is evidence to suggest a causal 
relationship between the IP and the AE. Types of evidence that would suggest a causal 
relationship between the IP and the AE include: a single occurrence of an event that is 
uncommon and known to be strongly associated with IP exposure (e.g., angioedema, hepatic 
injury, Stevens-Johnson Syndrome); one or more occurrences of an event that is not commonly 

Orasis Pharmaceuticals 
 
CSF-1 Ophthalmic Solution 
Protocol 20-150-0003 
 
 Version 2.0 (Amendment 1) 
IND # 131464

40 
 
associated with IP exposure, but is otherwise uncommon in the population exposed to the IP 
(e.g., tendon rupture); an aggregate analysis of specific events observed in a clinical trial (such as 
known consequences of the underlying disease or condition under investigation or other events 
that commonly occur in the study population independent of drug therapy) that indicates those 
events occur more frequently in the IP-treatment group than in a concurrent or historical control 
group. 
Expectedness 
The expectedness of an AE should be determined based upon existing safety information about 
the IP using these explanations: 
• Unexpected: an AE that is not listed in the Investigator’s Brochure (IB) or is not listed at 
the specificity or severity that has been observed. 
• Expected: an AE that is listed in the IB at the specificity and severity that has been 
observed. 
• Not applicable: an AE unrelated to IP. 
AEs that are mentioned in the IB as occurring with a class of products or as anticipated from the 
pharmacological (or other) properties of the product but are not specifically mentioned as 
occurring with the particular product under investigation are to be considered unexpected. 
The investigator should initially classify the expectedness of an AE. The final classification of an 
AE is subject to the sponsor’s determination. 
9.2 
Serious Adverse Events 
An AE is considered serious if, in the view of either the investigator or sponsor, it results in any 
of the following outcomes: 
• Death; 
• A life-threatening AE; 
Note: An AE is considered “life-threatening” if, in the view of either the investigator or 
sponsor, its occurrence places the patient or subject at immediate risk of death. It does not 
include an AE that, had it occurred in a more severe form, might have caused death. 
• Inpatient hospitalization or prolongation of existing hospitalization; 
Note: The term “inpatient hospitalization” refers to any inpatient admission (even if 
< 24 hours). For chronic or long-term inpatients, inpatient admission includes transfer 
within the hospital to an acute/intensive care inpatient unit. Inpatient hospitalization does 
not include: emergency room visits; outpatient/same-day/ambulatory procedures; 
observation/short stay units; rehabilitation facilities; hospice facilities; nursing homes; or 
clinical research/Phase 1 units. 
Note: The term “prolongation of existing hospitalization” refers to any extension of an 
inpatient hospitalization beyond the stay anticipated or required for the reason for the 
initial admission as determined by the investigator or treating physician. 
• A persistent or significant incapacity or substantial disruption of the ability to conduct 
normal life functions;

Note: A Serious Adverse Event (SAE) specifically related to visual threat would be 
interpreted as any potential impairment or damage to the subject’s eyes (e.g., intraocular 
hemorrhage, retinal detachment, central corneal ulcer, or damage to the optic nerve). 
• A congenital anomaly/birth defect. 
Important medical events that may not result in death, are life-threatening, or require 
hospitalization may be considered serious when, based upon appropriate medical judgment, they 
may jeopardize the patient or subject and may require medical or surgical intervention to prevent 
one of the outcomes listed in this definition. The medical monitor will review and determine the 
expectedness of any SAE following the investigator’s assessment.  
9.3 
Procedures for Reporting Adverse Events 
All AEs and their outcomes must be reported to 
, the study sponsor, and the IRB as required 
by the IRB, federal, state, or local regulations and governing health authorities and recorded on 
the appropriate subject source document and eCRF. 
Reporting a Suspected Unexpected Adverse Reaction 
All AEs that are ‘suspected’ and ‘unexpected’ are to be reported to 
the study sponsor, and 
the IRB as required by the IRB, federal, state, or local regulations and governing health 
authorities. 
Reporting a Serious Adverse Event 
To ensure subject safety, all SAEs, regardless of relationship to the study drug, must be 
immediately reported by the investigator to 
and the sponsor within 24 hours of becoming 
aware of the event. All information relevant to the SAE must be recorded on the appropriate 
source document, SAE Report Form, and eCRF, including all pertinent medical records, 
information, and medical judgments from colleagues who assisted in the treatment and follow-up 
of the subject, a complete case history, which includes a statement as to whether the event was or 
was not suspected to be related to the use of the IP. The investigator must also inform the IRB of 
the AE within their guidelines for reporting SAEs. The investigator is obligated to pursue and 
obtain information requested by 
 and/or the sponsor in addition to the information reported 
on the source document, SAE Report Form, and eCRF. All subjects experiencing an SAE must 
be followed-up with, and the outcome reported. 
Contact information for reporting SAEs: 
 
 
 
9.4 
Procedures for Unmasking (if applicable) 
Treatment assignment should not be communicated to the Contract Research Organization 
(CRO) or Sponsor and should not be recorded in any study documents or source document. 
When medically necessary, the investigator may need to determine what treatment has been 
assigned to a subject. When possible (i.e., in non-emergency situations), 
and/or the study 
sponsor should be notified before unmasking the study drug.

Type and Duration of the Follow-up of Subjects after Adverse Events 
The investigator will follow unresolved AEs to resolution, until the subject is lost to follow-up or 
until the AE is otherwise explained. Resolution means the subject has returned to baseline state 
of health or the investigator does not expect any further improvement or worsening of the AE. If 
the subject is lost to follow-up, the investigator should make 3 reasonable attempts to contact the 
subject via telephone, post, or certified mail. All follow-up will be documented in the subjects’ 
source document. Non-serious AEs identified on the last scheduled contact must be recorded on 
the source document with the status noted. 
If the investigator becomes aware of any new information regarding an SAE (i.e., resolution, 
change in condition, or new treatment), a new SAE Report Form must be completed and 
faxed/emailed to 
 and/or the study sponsor within 24 hours. The original SAE Report Form is 
not to be altered. The SAE Report Form should describe whether the event has resolved or 
continues and how the event was treated. 
 
10 STATISTICAL HYPOTHESES AND METHODS OF ANALYSES  
10.1 General Considerations  
In general, quantitative/continuous data will be summarized using descriptive statistics (n, mean, 
standard deviation (SD), median, minimum, and maximum). Qualitative/categorical data will be 
summarized using frequencies and percentages. Statistical testing, unless otherwise indicated, 
will be performed at a 2-sided 0.05 significance level.  
For all variables, baseline is defined as the pre-randomization measurement taken at Visit 2 (Day 
1), prior to administration of study drug. Change from baseline will be calculated as follow-up 
measure minus baseline measure. 
10.2 Hypotheses 
The primary efficacy hypothesis is: 
H01: The difference between study eyes treated with CSF-1 and study eyes treated with Vehicle, 
in the percentage of study eyes with a ≥ 3-line (15-letter) improvement from baseline in BDCVA 
at 40 cm (Precision Vision chart) without a loss in best distance corrected VA of ≥ 5 letters 
(ETDRS at 4m) at Visit 3 (Day 8), 1 hour post-Dose 1 = 0. 
H11: The difference between study eyes treated with CSF-1 and study eyes treated with Vehicle, 
in the percentage of study eyes with a ≥ 3-line (15-letter) improvement from baseline in BDCVA 
at 40 cm (Precision Vision chart) without a loss in best distance corrected VA of ≥ 5 letters 
(ETDRS at 4m) at Visit 3 (Day 8), 1 hour post-Dose 1 ≠ 0. 
The study will be considered a success if the null hypothesis, H01, is rejected at a 2-sided alpha 
= 0.05 in favor of CSF-1 in the alternative hypothesis, H11, tested as delineated in the primary 
efficacy analysis section, and the following secondary efficacy hypotheses will each be tested as 
stated under adjustments for multiplicity.

Adjustments for Multiplicity 
The following testing strategy will be employed to adjust for multiplicity: 
If the primary null hypothesis, H01, is rejected at a 2-sided alpha = 0.05 in favor of CSF-1 in the 
alternative hypothesis, H11, tested as delineated in the primary efficacy analysis section, then the 
study will be considered a success and the following secondary hypotheses will be tested in 
hierarchical order, each at a 2-sided alpha = 0.05, where inference will be made on each null 
hypothesis only if the prior null hypotheses are rejected in favor of CSF-1 
1) Visit 3 (Day 8), 2 hours following Dose 1 (H02) 
2) Visit 3 (Day 8), 1 hour following Dose 2 (H03) 
3) Visit 3 (Day 8), 2 hours following Dose 2 (H04)

10.3 Study Populations  
• Full Analysis Set – The full analysis set (FAS) will include all randomized subjects who 
have received at least one dose of the study drug. Subjects in the FAS will be analyzed as 
randomized. 
• Per Protocol Set – The per-protocol (PP) set will include subjects in the FAS who do not 
have significant protocol deviations that affect the primary endpoint analysis. Protocol 
deviations will be assessed prior to database lock and unmasking. Subjects in the PP set 
will be analyzed as treated. 
• Safety Set – The safety set will include all subjects who have received at least one dose 
of the study drug. Subjects in the safety population will be analyzed as treated.  
10.4 Unit of Analysis 
The study eye will be used for all monocular analyses. The fellow eye will inherently be 
included in all binocular analyses. Both eyes will be displayed and analyzed for all ophthalmic 
safety variables. 
The study eye will be defined by the study Investigator as the eye that meets all enrollment 
criteria. If both eyes meet all enrollment criteria, then the eye with the worse Visit 2 pre-
treatment/baseline BDCVA at 40 cm (Precision Vision chart) will be the study eye. If both eyes 
have the same BDCVA at 40 cm, the right eye will be the study eye.

10.5 Sample Size 
A total sample size of 280 subjects (140 subjects per arm) yields >97.5% power to establish 
superiority of CSF-1 to Vehicle in the percentage of study eyes demonstrating a ≥ 3-line (15-
letter) gain from baseline in BDCVA at 40 cm (Precision Vision chart) and no loss of best 
distance corrected VA ≥5 letters (ETDRS at 4m), 1-hour post each dose on Visit 3 (Day 8) 
assuming a response rate of 42.5% in CSF-1 and 17.5% in Vehicle using a Pearson chi-squared 
test with a 2-sided significance level of 0.05. 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
Accounting for approximately a 5% discontinuation rate, approximately 150 subjects per arm 
(approximately 300 total) will be randomized. 
Estimates were obtained from the Phase 2 study (18-150-0006) Intent-to-Treat (ITT) population 
response for pilocarpine 0.4% vs. diclofenac (control), additionally imputing missing data as 
failures.  
At least approximately 30% of subjects will have light (i.e., blue, green, gray, and hazel) iris, and 
at least approximately 30% will have a brown iris. The actual percentages will vary based on 
enrollment. 
10.6 Demographic and Baseline Characteristics  
Subject demographics including age, gender, race, ethnicity, and iris color will be presented 
using summary statistics (mean, SD, minimum, maximum, and median) or frequency counts and 
percentages as appropriate.  
10.7 Efficacy Analysis  
Primary Efficacy Analyses  
The primary efficacy endpoint in this study is the percentage of subjects with a ≥ 3-line (15-
letter) gain, from baseline, in best distance-corrected visual acuity (BDCVA) at 40 cm (Precision 
Vision chart) and no loss in best distance corrected visual acuity ≥ 5 letters (ETDRS chart) at 
Visit 3, 1 hour following Dose 1 in the study eye. The primary efficacy analysis will be 
conducted in the FAS with intercurrent events handled in the following manners:

1) Discontinuation of study drug and non-optimal compliance will be ignored [treatment 
policy strategy]. 
2) Withdrawal due to lack of efficacy or adverse events: missing data will be singly imputed 
as failure [hypothetical strategy]. 
3) Missing data without withdrawal or withdrawal due to reasons other than lack of efficacy 
or adverse events: missing data will be imputed employing Multiple Imputation (MI) 
using randomized treatment-based Markov Chain Monte Carlo (MCMC) methodology 
[hypothetical strategy]. 
No subject data will be excluded from the FAS due to protocol violations/deviations. The FAS 
will be used for the primary efficacy analyses. Note that multiple imputations of missing values 
will be completed for the continuous measures (BDCVA at 40 cm and best distance corrected 
VA at 4m), then the response variable will be determined therefrom. 
 
 
 
 
Descriptive statistics will be presented by treatment group. Testing of the percentage of subjects 
with at least a 3-line (15-letter) improvement from baseline in BDCVA at 40 cm without a loss 
of ≥ 5 letters in best distance corrected VA at 4m will be completed separately for the 1 hour and 
2 hour time points using a generalized linear mixed model with a binomial distribution including 
fixed effects of baseline BDCVA at 40 cm as a covariate, daily dose (Dose 1 and Dose 2), 
treatment, and the interaction of dose with treatment and random effect of subject to account for 
the correlation within a subject between daily doses. 
 
 
 
 
 
 
  
The adjusted odds ratios and marginal proportions and difference in proportions along with 
corresponding two-sided 95% Confidence Intervals (CIs) and p-values will be presented. 
Treatment comparisons will also be made separately for each time point and dose using logistic 
regression model including fixed effects of baseline BDCVA at 40 cm as a covariate and 
treatment, Pearson’s chi-squared test or Fisher’s exact test if any of the cell counts are less than 
five as a sensitivity analysis to the primary model above.  
Secondary Efficacy Analysis 
For the secondary efficacy endpoints of BDCVA at 40 cm, the percentage of subjects who 
achieve a ≥ 3-line (15-letters) improvement from baseline without a loss of ≥ 5 letters in best 
distance corrected VA at 4m for each Visit, time point and daily dose (Dose 1 and Dose 2) will 
be summarized and analyzed using the same imputation as the primary efficacy endpoint. The 
same modeling strategy will be used as detailed in the primary efficacy analysis for any time 
point that is measured after both doses within the visit [e.g.: 2 hours at Visit 3 (Day 8); 30 
minutes, 1 and 2 hours at Visit 2 (Day 1); and 20 minutes, 1, 2, and 3 hours at Visit 4 (Day 15)]. 
For those time points that are measured only after the second dose within the visit

10.8 Safety Analysis 
Verbatim descriptions of AEs will be mapped to Medical Dictionary for Regulatory Activities 
(MedDRA) terms and be presented in a data listing. Treatment Emergent AEs (TEAEs), those 
that occur after the first dose of study drug, will be summarized by treatment group using 
frequency and percent for each System Organ Class (SOC) and Preferred Term (PT) within each 
SOC. Similar summaries will also be presented for serious TEAEs, TEAEs leading to death, 
TEAEs leading to study drug discontinuation, TEAEs related to IP and TEAEs by severity. 
When reporting the incidence of AEs, a subject will only be counted once if they ever experience 
an event within the SOC and ever experience the individual PT within the SOC. 
Actual results and changes from baseline results in monocular and binocular BCVA at 4m and 
Low- Luminance BCVA, slit-lamp biomicroscopy, conjunctival redness grading, IP drop 
comfort, IOP, and dilated fundus examination will be summarized descriptively at each visit by 
treatment group. 
Full details of the safety analyses will be specified in the formal SAP.

10.10 Missing Data 
The primary efficacy analyses will be conducted with missing data and intercurrent events 
handled in the following manners:  
1) Discontinuation of study drug and non-optimal compliance will be ignored 
[treatment policy strategy]. 
2) Withdrawal due to lack of efficacy or adverse events: missing data will be singly 
imputed as failure [hypothetical strategy]. 
3) Missing data without withdrawal or withdrawal due to reasons other than lack of 
efficacy or adverse events: missing data will be imputed employing Multiple 
Imputation (MI) using randomized treatment-based Markov Chain Monte Carlo 
(MCMC) methodology [hypothetical strategy]. 
Sensitivity analyses on the primary efficacy variable will be performed using the FAS with all 
missing data imputed as failures, the FAS with observed data, and PP set with observed data. 
Additional sensitivity analyses such as control-based pattern mixture model MIs and tipping 
point may be performed and will be specified in the Statistical Analysis Plan (SAP). 
 
10.11 Adjustment for Multiplicity 
If the primary null hypothesis, H01, is rejected at a 2-sided alpha = 0.05 in favor of CSF-1 in the 
alternative hypothesis, H11, tested as delineated in the primary efficacy analysis section, then the 
study will be considered a success and the following secondary hypotheses will be tested in 
hierarchical order, each at a 2-sided alpha = 0.05, where inference will be made on each null 
hypothesis only if the prior null hypotheses are rejected in favor of CSF-1

All subjects have the right to withdraw consent at any time during the study period. If informed 
consent is taken under special circumstances (oral informed consent), then the procedures to be 
followed must be determined by 
and/or the sponsor and provided in writing by 
 and/or 
the sponsor prior to the consent process. 
IRB Approval 
This study is to be conducted in accordance with IRB regulations (U.S. 21 CFR Part 56.103). 
The investigator must obtain appropriate IRB approval before initiating the study and re-
approval at least annually. 
Only an IRB-approved version of the ICF will be used. 
11.2  Ethical Conduct of the Study 
This study will be conducted in accordance with the ethical principles that originated with the 
Declaration of Helsinki. 
11.3  Subject Confidentiality 
All personal study subject data collected and processed for the purposes of this study should be 
maintained by the investigator and his/her staff with adequate precautions to ensure that the 
confidentiality of the data is in accordance with local, state, and federal laws and regulations. 
Monitors, auditors and other authorized representatives of 
 the sponsor, the IRB approving 
this study, the FDA, the Department of Health and Human Services, other domestic government 
agencies, and other foreign regulatory agencies will be granted direct access to the study 
subjects’ original medical and study records for verification of the data and/or clinical trial 
procedures. Access to this information will be permitted to the aforementioned individuals to the 
extent permitted by law. 
A report of the results of this study may be published or sent to the appropriate health authorities 
in any country in which the study drug may ultimately be marketed in, but the subjects’ identity 
will not be disclosed in these documents. 
11.4  Documentation 
Source documents may include a subject’s medical records, hospital charts, clinic charts, the 
investigators’ subject files, as well as the results of diagnostic tests such as radiographs, 
laboratory tests, and electrocardiograms. The investigators’ copy of the eCRFs serves as the 
investigators’ record of a subjects’ study-related data. 
Retention of Documentation 
All study-related correspondence, patient records, consent forms, records of the distribution and 
use of all study drug, and copies of case report forms should be maintained on file for at least 2 
years after the last approval of a marketing application in an ICH region and until there are no 
pending or contemplated marketing applications in an ICH region; or until at least two years 
have elapsed since the formal discontinuation of clinical development of the study drug. These 
documents will be retained for a longer period if required by the applicable regulatory 
requirements or by an agreement with the sponsor. It is the responsibility of the sponsor to 
inform the investigator/institution as to when these documents no longer need to be retained. 
If the responsible investigator retires, relocates, or for other reasons withdraws from the 
responsibility of keeping study records, custody must be transferred to a person who will accept

Study Drug 
Labeling/Packaging 
Vehicle for screening and study drug will be packaged and labeled into clinical kits for screening 
and treatment. Vehicle for screening will be labeled and packaged into screening kits containing 
1 pouch each. After randomization, each subject will be assigned a single master kit containing 
two smaller (inner) kits of study drug for treatment. Each inner kit will be comprised of 5 
pouches containing one strip of 5 vials containing IP or vehicle. Each master kit will be uniquely 
identified by the kit number; the 2 inner kits inside will bear the same kit number with an 
additional designation indicating the visit at which each is to be dispensed (i.e., Visit 2 or Visit 
3). Screening kit, master kit, and inner kit labels will also include a space for the site to enter 
each subjects’ subject number and initials upon kit assignment.  
Clinical label texts for the packaging will meet applicable regulatory requirements and include 
the statement “Caution: New Drug-Limited by Federal Law to Investigational Use.”  
Storage of Investigational Product 
Study drug and Vehicle for screening must be stored in a secure area of the investigative site, 
accessible only to the investigator or designees, refrigerated between 2° to 8°C (36° to 46°F). A 
temperature log must be recorded throughout the course of the study, once every business day 
with the minimum and maximum temperature. Study drug will be administered/dispensed only 
to subjects entered into the clinical study, in accordance with the conditions specified in this 
protocol. Subjects will be instructed to store dispensed study drug under refrigerated conditions, 
and transport study drug kits to their homes using cooler bags and an ice pack provided by the 
site at the time of dispensation. All study drug will be returned to inventory after use in the 
provided return bags. Please refer to the IP manual for additional information.  
Accountability of Study Drug 
Study drug (IP and Vehicle) is to only be administered by study personnel and is to only be used 
in accordance with this protocol. Study drug must only be distributed to subjects properly 
qualified under this protocol to receive study drug. 
Sites must keep an accurate accounting of the study drug received from the supplier. This 
includes the amount of study drug administered to subjects and the amount returned or disposed 
throughout the course of the study. A detailed inventory must be completed for the study drug. 
Return or Disposal of Study Drug 
All study drug will be returned to the sponsor or their designee or destroyed. The return or 
disposal of study drug will be specified in writing. Any remaining study drug will be collected 
from the subject at Visit 3 and Visit 4 before study exit. Further details on labeling, packaging, 
storage, accountability, and return or disposal of study drug can be found in the IP Manual. 
11.6 Recording of Data on Source Documents and Electronic Case Reports 
Forms (eCRFs) 
The investigator is responsible for ensuring that study data is completely and accurately recorded 
on each subjects’ source document, eCRF, and all study-related material. All study data should

also be attributable, legible, contemporaneous, and original. Recorded datum should only be 
corrected in a manner that does not obliterate, destroy, or render illegible the previous entry 
(e.g., by drawing a single line through the incorrect entry and writing the revision next to the 
corrected data). An individual who has corrected a data entry should make clear who made the 
correction and when by adding to the correction his/her initials as well as the date of the 
correction.
