Protocol Synopsis 
Study Title:  A Phase 1/2a Assessment of WB007 Ophthalmic Solution in Subjects with 
Primary Open-Angle Glaucoma or Ocular Hypertension 
Investigational Product:  WB007 (also known as AGN-227535) 
Phase:  1/2a 
Study Objectives:  The objective of this study is to assess the safety, ocular tolerability and 
IOP-lowering effects of AGN-227535 in adult subjects with bilateral primary open-angle 
glaucoma or ocular hypertension. 
Clinical Hypotheses:   
Parts 1/2:  
AGN-227535 has an acceptable safety and tolerability profile; 
Part 1: 
The safety profile allows for assessing AGN-227535 in Part 2; 
Part 2:   
At least 1 concentration of AGN-227535 demonstrates an IOP lowering effect. 
Type of Study:  Two-part, multi-centered [(Part 1- single-dose in one eye, open-labeled, 
dose-escalation), (Part 2 - multiple-dose, randomized, double-masked, active-controlled)], 
bilateral treatment.  
Study Population: Adult (at least 18 years of age) male or female subjects with primary 
open-angle glaucoma or ocular hypertension in each eye who are otherwise in generally good 
health.  Only one eye must meet all ocular entry criteria.   
Number of Subjects and Sites: Approximately 100 subjects will be screened to participate 
in the study (Part 1 – 25; Part 2 – 75).  An expected 95 subjects will be assigned to study 
treatment such that approximately 18 (Part 1) and 60 (Part 2) subjects complete the study at 
3-5 sites.  Subjects who do not complete the study may be replaced.   
Part 1: 
Approximately 6 subjects per dose-escalation cohort (up to 3). 
Part 2:  
Up to 2 investigational doses will be chosen based on results from Part 1.  
Approximately 24 subjects per AGN-227535 group and approximately 12 subjects 
for the timolol group will be given study treatment.   
Duration of Study Participation:   
Part 1: 
Up to 2 months from Screening through Day 2/Exit;   
Part 2: 
Up to 2.5 months from Screening through Day 14/Exit. 
Study Treatments:  AGN-227535 Ophthalmic Solution (Parts 1 and 2) and timolol 0.5% 
ophthalmic solution (as a control in Part 2 only) 
Part 1: 
Study Treatments 1-3:   AGN-227535 (0.05%; 0.15%; 0.40%);   
Part 2: 
Up to 2 AGN-227535 study treatments and Timolol 0.5% (Study Treatment 4). 
Dosage/Dose Regimen:   
Part 1: 
Subjects will be given 1 dose of study treatment to one eye in the morning 
(administered by site personnel). 

Whitecap Biosciences

2021.01.30 
Part 2: 
Subjects will dose study treatment every morning and every evening 
(approximately 12 hours apart) to each eye for up to 14 days.  Site personnel will 
administer the morning dose at study visits. 
Randomization/Stratification: 
Part 1: 
If only one eye qualifies, the study medication will be administered to that eye.  If 
both eyes qualify, the eye with the higher IOP at Baseline (Day -1) Hour 0 will be 
the study eye and will receive study medication.  If both eyes have the same IOP 
value at this timepoint, the right eye will be the study eye. 
Part 2: 
Part 2:  Subjects will be randomly assigned to 1 of up to 3 treatment arms (based 
on results from Part 1) in a 2(:2):1 allocation ratio to receive 1 of up to 2 AGN-
227535 concentrations or timolol 0.5% in each eye.  The randomization will be 
stratified by baseline IOP (IOP ≤ 25 mm Hg and > 25 mm Hg at Hour 0) and 
performed centrally (ie, across sites).  Randomization and stratification will be 
performed using the Interactive Web Response System (IWRS), a module within 
the electronic data capture (eDC) system. 
Visit Schedule:  
Part 1: 
Screening (days -50 to -4, including washout/waiting period as required); Baseline 
(Day -1), Day 1, Day 2/Exit 
Part 2: 
Screening (days -50 to -4, including washout/waiting period as required; Baseline 
(Day -1), Day 1, Day 4 and Day 14/Exit. 
Primary Efficacy Endpoint (Part 2 only):  Mean change from baseline in IOP 
Statistical Method for primary endpoint:   
In general, data will be summarized with descriptive statistics which will include sample 
size, mean, standard deviation, median, minimum and maximum for continuous variables 
and frequency and percentage for categorical variables. 
The Medical Dictionary for Regulatory Activities (MedDRA) nomenclature will be used to 
code adverse events. The number and percentage of subjects with adverse event reports will 
be tabulated for all treatment-emergent adverse events (TEAEs) regardless of causality, 
treatment-related TEAEs, all serious TEAEs, treatment-related serious TEAEs, and all 
adverse events leading to premature discontinuation of study treatment.  
Analysis populations: Each population will be analyzed based on the treatment received. 
Part 1:  
The Safety population consisting of all treated subjects will be used for all 
analyses.  All safety and IOP-lowering effects tabulations will provide descriptive 
statistics by cohort. 
Part 2: 
The Safety population, as defined above, will be used for analyses of all Safety 
data. In addition to the Safety population two other populations are defined for 
analyses of Part 2 efficacy data: 

Whitecap Biosciences 
Confidential 
 Protocol WB007-001_05

2021.01.30 
The Modified Intent-to-treat (mITT) will consist of all randomized and treated subjects who 
provide IOP data at baseline and at least one post-baseline IOP assessment.  This population 
will be used for analyses of efficacy data.  
The Per-protocol (PP) population is a subset of the mITT population and will consist of 
subjects who did not have any major protocol violations deemed to have potential impact on 
the primary endpoint.  This population will be used to confirm the primary efficacy analysis. 
The primary efficacy endpoints are the Day 14/Exit mean IOP changes from Baseline (Day -
1) at each time-matched hour (0, 2, 4, 8) in the study eye.  The primary efficacy analysis will 
be within-group mean change from baseline IOP at hour 2, the time of peak effect of timolol.  
Between treatment group comparative analyses will be performed in the mITT population via 
analysis of covariance (ANCOVA) tests which will have treatment as the main effect and the 
baseline hour-matched IOP as the covariate in the model.  Pairwise treatment group 
comparisons will be performed for each individual dose of AGN-227535 ophthalmic solution 
versus timolol ophthalmic solution 0.5%.  Confidence intervals (95%) based on this 
ANCOVA model will be provided for the differences between treatment groups.  AGN-
227535 will be considered to be non-inferior to Timolol 0.5% if the upper limit of the 95% 
CI does not exceed 1.5 mm Hg at the majority of timepoints evaluated (ie, 3/4) at the Day 
14/Exit visit.  If AGN-227535 ophthalmic solution is determined to be non-inferior to 
Timolol ophthalmic solution 0.5%, a further attempt to show superiority of AGN-227535 
over Timolol will be made.  These analyses will also be performed on the PP population.  As 
this is an exploratory trial, all treatment comparisons will be made at the two-sided α = 0.05 
level without adjustment for multiple comparisons. 
Additional safety analyses will include evaluation of peak severity of macroscopic hyperemia 
and hyperemia as evaluated on biomicroscopy at each post-baseline visit (Days 4 and 14) and 
across all post-baseline time points. 
Sample Size Calculation:  For each cohort in Part 1 of the study a sample size of 6 patients 
will provide 83% power to detect a 3 mm Hg within-group change from pre-dose assuming a 
standard deviation of 2 and two-sided alpha = 0.05.  
Part 2 sample size will provide >90% power to detect within-group and between-group 
treatment differences of mean change from baseline of at least 3 mm Hg for the primary 
endpoint assuming a standard deviation of 2.5 with two-sided alpha = 0.05.  With a treatment 
group difference of -1 mmHg, the power ranged from 50% for a common SD of 3.5 to 78% 
for a common SD of 2.5 to conclude non-inferiority based on a 1.5 mmHg margin and a 1-
sided alpha = 0.025. 
Data Monitoring Committee:  No formal Data Monitoring Committee is planned.  Between 
dose-escalation groups in Part 1, all available data collected to date will be used to assist in 
decision making to continue to the next dose or to stop the study.  All data collected in Part 1 
will be used to select 1 or 2 concentrations of AGN-227535 to evaluate in Part 2.  The 
decision to proceed or to stop the study will be made by the Medical Monitor, the Head of 
Clinical and the Chief Executive Officer.  All decisions will be documented.

Background and Rationale 
1.1. 
Background 
Ocular hypertension, or chronically elevated intraocular pressure (IOP), is a major risk factor 
for optic nerve injury and sight loss associated with glaucoma (AGIS, 2000; Heijl et al, 
2002); therefore, a primary goal of glaucoma management is to reduce IOP.  Brimonidine 
(ALPHAGAN®, ALPHAGAN® P) is a potent alpha2 adrenergic receptor full agonist that is 
used clinically for long-term management of increased IOP.  However, due to its relatively 
short duration of action, it is labelled in the United States for administration three times daily 
(TID).  An alpha-agonist with an improved pharmacokinetic profile could lead to higher 
therapeutic drug levels or decreased dosing which may provide an opportunity for better IOP 
management.  
Whitecap Biosciences plans to conduct an initial 2-part clinical study to evaluate the safety 
and IOP-lowering effects of AGN-227535 ophthalmic solution in adult patients with primary 
open-angle glaucoma (POAG) or ocular hypertension (OHT).  Part 1 will be an open-label, 
single-dose, dose-escalation assessment of up to 3 concentrations (0.05% 0.15%, 0.4%) of 
AGN-227535 administered unilaterally to assess initial safety, tolerability and IOP-lowering 
effects.  Results from Part 1 will determine concentration(s) to assess in Part 2.  In Part 2, up 
to 2 concentrations of AGN-227535 will be administered bilaterally, twice-daily for up to 14 
days and compared to timolol as the active control.  The non-clinical data package supports 
twice-daily dosing of AGN-227535 0.4% for up to 28 days in humans. 
1.2. 
Investigational Product  
AGN-227535 is a pivalate ester prodrug that undergoes enzymatic hydrolysis in the cornea to 
yield the active metabolite, AGN-222390.  Whereas AGN-227535 is only a weak alpha2 
agonist, AGN-222390 is a potent alpha2 adrenergic receptor pan-agonist that exhibits partial 
agonism at the alpha2A receptor AGN-222390 is also the 3-methyl hydroxylated metabolite 
of dexmedotomidine  a marketed drug used to produce short-term sedation of patients in the 
critical care setting.  
A detailed description of the chemistry, non-clinical pharmacology and toxicology of AGN-
227535 is provided in the Investigator’s Brochure.  
1.3. 
Summary of Nonclinical Studies  
Nonclinical studies have been conducted with AGN-227535 to assess pharmacology, 
pharmacokinetics and toxicology (both locally and systemically) from ocular and oral 

Whitecap Biosciences 
Confidential 
 Protocol WB007-001_05 
 
15 
2021.01.30 
administration using various models including in vitro, rat, rabbit, dog, and nonhuman 
primates.  The focus of the nonclinical testing strategy was 3-fold: to establish whether AGN-
227535 is differentiated from brimonidine relative to attributes that may form the basis for a 
better therapy for IOP management; to validate the conversion of the prodrug to the active 
metabolite and to enable the conduct of clinical testing of AGN-227535 with completion of 
the prerequisite IND-enabling toxicology studies.  
Below is a high-level summary of findings from the nonclinical studies: 
• AGN-227535 is a pivalate ester prodrug that is enzymatically hydrolyzed as it passes 
through the cornea to its active metabolite, AGN-222390; 
• AGN-222390 is a potent alpha2 receptor pan-agonist that exhibits partial agonism at the 
alpha2A receptor whereas its parent, AGN-227535, exhibits only weak activity;  
• AGN-222390 may offer advantages over brimonidine including less potential for receptor 
down regulation (tachyphylaxis) and a longer duration of IOP reduction; 
• Pharmacological and pharmacokinetic evidence indicate that AGN-222390 is the 
pharmacologically active moiety; 
• Ocular instillation of AGN-227535 is well tolerated at the proposed clinical 
concentrations and did not result in adverse morphological changes; 
• Systemic effects of AGN-227535 are largely the known pharmacologic effects of alpha2 
receptor agonists and include decreased intestinal motility, arterial hypotension, 
bradycardia, and sedation.  In some cases, these were transient. The pharmacologic 
systemic adverse effects are monitorable and reversible. At higher doses than the planned 
human equivalent starting dose, adverse cardiovascular effects and/or decreased GI 
motility were the likely cause(s) of death observed following oral administration in 
rats.  The lower systemic exposure achieved with topical ocular dosing suggests that 
cardiovascular effects are unlikely to occur with the topical dose (up to 0.4%) and dosing 
frequency (twice-daily) in this clinical study; 
• Morphological changes in the dog testes and epididymides were observed at the highest 
dose tested in a 14-day oral toxicity study but not in the 1-month oral toxicity study at 
equivalent or higher doses; 
• Overall, systemic effects of topically applied AGN-227535 at concentrations of up to 
0.4% dosed twice daily are not expected in humans given the administration of a 
relatively small administered dose and a much larger central volume compared to the 
toxicology species; 
• AGN-227535 and AGN-222390 are not mutagenic or clastogenic. 
Details of the non-clinical pharmacology, pharmacokinetics and toxicology of AGN-227535 
is provided in the Investigator’s Brochure. The non-clinical profile of AGN-227535 supports

 Protocol WB007-001_05

the planned twice-daily dosing regimen of concentrations of up to 0.4% and the 2-week study 
duration in this clinical study.  This study will be conducted in compliance with the protocol, 
International Conference on Harmonization guidance and Good Clinical Practices.  
1.4. 
Benefit/Risk Assessment 
This is the first clinical study of AGN-227535 in humans; the potential benefits may be 
identifying an alpha-agonist with a longer duration of action and a better safety profile than 
currently available alpha-agonist treatments for IOP lowering.  Detailed information about 
the potential and/or known risks and potential adverse events of AGN-227535 may be found 
in the Investigator’s Brochure. 
2. 
Study Purpose, Objectives, and Clinical Hypothesis(es)   
Overall Study Purpose  
The purpose of this study is to assess initial ocular and systemic safety in humans of AGN-
227535 ophthalmic solution and to assess its potential to lower IOP in subjects with 
glaucoma or ocular hypertension.  
Study Objective(s) 
The objective of this study is to assess the safety, ocular tolerability and IOP-lowering effects 
of AGN-227535 in adult subjects with primary open-angle glaucoma or ocular hypertension. 
Clinical Hypotheses  
Parts 1/2: 
AGN-227535 has an acceptable safety and tolerability profile. 
Part 1: 
The IOP-lowering effects of at least 1 concentration of AGN-227535 are 
sufficient for evaluation to proceed to Part 2;  
Part 2: 
The IOP effects of at least 1 concentration of AGN-227535 demonstrate 
adequate IOP lowering; 
3. 
Study Design and Rationale 
Study Design Description:  This is a 2-part study designed to evaluate the safety, tolerability 
and IOP-lowering effects of AGN-227535 in subjects with primary open-angle glaucoma 
(POAG) or ocular hypertension (OHT).   Approximately 100 subjects are planned to be 
enrolled at up to approximately 5 study centers in the United States. 
In Part 1, an open-label dose-escalation of AGN-227535 0.05%, 0.15% and 0.4% is planned 
in order to assess initial safety, tolerability and IOP-lowering effects.  Approximately 6 
subjects will be exposed to a single dose (to one eye) at each concentration level.  Between 

Whitecap Biosciences 
Confidential 
 Protocol WB007-001_05 
 
17 
2021.01.30 
cohorts, all available data will be used to assess the appropriateness to pursue the next 
concentration.  Approximately 25 subjects will be screened so that 18 subjects complete the 
study.   
In Part 2, In addition to the primary analysis of the within-group mean IOP change from 
baseline, a parallel comparison of AGN-227535 with timolol 0.5% is planned.  Study 
treatments will be administered twice-daily for 14 days.  Up to 2 investigational doses will be 
chosen based on results from Part 1.  Subjects will be randomized in a 2(:2):1 ratio to receive 
one of up to two concentrations of AGN-227535 (based on results from Part 1) or timolol 
ophthalmic solution 0.5% and will be stratified based on IOP at Baseline, Hour 0 (≤ 25 mm 
Hg versus > 25 mm Hg).  Approximately 24 subjects per AGN-227535 group and 12 subjects 
for the timolol group will be given study treatment.  If 2 investigational doses are selected: 
approximately 75 subjects will be screened so that 60 subjects complete the study.  
For both Parts 1 and 2, potential subjects will be screened within the 50 days prior to 
initiation of treatment.  Thus, the total duration of study participation for each subject is up to 
2.5 months which includes 4 (Part 1) and 5 (Part 2) in-clinic visits.  The visit schedule 
requires day-long visits at some time points to perform sufficient clinical assessments.  The 
primary efficacy endpoint (Part 2) is IOP change from baseline at each time-matched hour at 
Day 14/Exit. 
Subject safety will be monitored throughout the study.  
Rationale for the Study Design:  Part 1 of this first in-human study will be conducted in a 
dose-escalation approach to assess the initial safety, tolerability and IOP-lowering effects of 
AGN-227535 following a single dose.  Part 2 will be conducted as a 14-day assessment of 
the safety, tolerability and IOP-lowering effects of AGN-227535 dosed bilaterally BID to 
evaluate the short-term potential to lower IOP with an acceptable safety/tolerability profile. 
Timolol, an accepted standard of care treatment, will be used as the control in Part 2. 
Rationale for Dose and Route of Administration:  Alpha-2 agonists are well-characterized.  
For  AGN-227535 approximately 44- to 714-fold safety margins were derived from the 
systemic, local (ocular), cardiovascular, and pulmonary toxicology studies in rats and/or dogs 
(Studies TX11082, TX11057, TX11154, and TX11120); these margins are considered to be 
sufficient to support the clinical starting dose of 0.05% AGN-227535 with up to BID bilateral 
administration in subjects with POAG or OHT.  As a topical eyedrop, the route of 
administration is considered appropriate.

2021.01.30 
 Rationale for Duration of Observation:  As the first-in-humans study, it is appropriate to 
take a measured approach with limited exposure to confirm the non-clinical results.  Alpha-
agonists are well-characterized in humans and based on results of Part 1, a planned 14-day 
assessment is appropriate. 
3.1. 
Study Endpoints 
3.1.1. 
Primary Efficacy Endpoint(s) 
The primary efficacy endpoint is mean change from baseline in IOP at each time-matched 
hour of Day 14/Exit (Hours 0, 2, 4 and 8).   
3.1.2. 
Secondary Efficacy Endpoint(s) 
Mean IOP at Day 14/Exit.   
3.2. 
Methods for Randomization, Stratification, Masking, and 
Minimization of Bias  
3.2.1. 
Randomization and Stratification (Part 2 Only) 
Subjects will be randomly assigned to 1 of up to 3 treatment arms (based on results from Part 
1) in a 2(:2):1 allocation ratio to receive 1 of up to 2 AGN-227535 concentrations or timolol.   
To ensure balance of elements that could influence the IOP-lowering effects across treatment 
groups, the randomization will be stratified by baseline (Hour 0) IOP (≤25 mm Hg; >25 mm 
Hg). 
The randomization scheme will be prepared by Whitecap Biosciences Biostatistics or its’ 
designee. The IWRS, a module within eDC, will be used to confirm Baseline IOP eligibility 
and in Part 2 only, stratification and randomization of subjects.     
3.2.2. 
Masking 
Part 1: Subject treatment will not be masked.  If both eyes qualify, the eye with the higher 
IOP at Baseline (Day -1) Hour 0 will be the study eye and will receive study medication.  If 
both eyes have the same IOP value at this timepoint, the right eye will be the study eye.   
Part 2: Subject treatment will be double-masked; neither the investigator nor the staff or 
subject will be aware of treatment assignment.  All study treatments will be provided in 
similarly-appearing bottles with the same colored bottle caps and identical cartons to 
maintain masking of the study. 

Whitecap Biosciences

 Protocol WB007-001_05 
 
19 
2021.01.30 
3.2.3. 
Minimization of Bias 
The study design is that of a well-controlled clinical trial that includes elements necessary for 
a valid ascertainment of the effectiveness of treatment.  Part 2 of the study is randomized and 
double-masked to minimize investigator and subject bias.  A parallel-group design eliminates 
possible confounding effects that are inherent in other study designs (eg, crossover).  The 
selection of subjects, study endpoints, and therapy are in general similar to studies that 
established the safety and efficacy of other IOP-lowering treatments of subjects with 
glaucoma or ocular hypertension.  Subjects who are chronically treated with ocular 
hypotensive medications will be required to undergo appropriate washout periods prior to 
study entry to eliminate residual effects of other active ocular hypotensive medications. 
3.3. 
Treatment Stopping Rules and Discontinuation Criteria  
3.3.1. 
Treatment Stopping Rules  
There are no specific treatment stopping rules.  On an ongoing basis, all available safety data 
will be reviewed by the sponsor.  If two or more adverse events of the same kind that are 
severe in nature and considered possibly study drug related occur, a decision will be made as 
to whether to stop enrollment of the cohort (Part 1 only), to add subjects to a lower 
concentration cohort (Part 1 only), to stop the study and exit all subjects, or to continue the 
study and proceed as planned (see Section 3.4 for details on decision making). 
3.3.2. 
Discontinuation Criteria 
Subject Discontinuation 
Whitecap Biosciences, or the investigator, may decide to discontinue subjects who are 
enrolled into the study but who had significant deviation from protocol-specified 
inclusion/exclusion criteria. 
If a subject meets any of the following criteria, s/he must be exited from the study (see Early 
Exit Procedures, Section 8.9).   
• The investigator or Whitecap Biosciences deems that it is unsafe for the subject to 
continue in the study; 
• Subject indicates that s/he no longer want to participate in the study. 
Subjects will be discontinued from the study under the following circumstances:  if a female 
subject becomes pregnant during the study, the investigator will notify Whitecap Biosciences 
immediately after the pregnancy is confirmed, the subject should not receive further study 
treatment and she must be exited from the study and the pregnancy followed to term (see 

Whitecap Biosciences 
Confidential 
 Protocol WB007-001_05 
 
20 
2021.01.30 
Section 8.9 for Early Exit Procedures and Section 6.4.3 for Procedures for Pregnancy 
Follow-up and Reporting). 
Subjects who are exited before completing the study may be replaced following consultation 
with sponsor. 
Study Discontinuation 
The study may be stopped at a study site at any time by the site investigator.  Whitecap 
Biosciences may stop the study (and/or the study site) for any reason with appropriate 
notification. 
3.4. 
Decision Making During Parts 1 and 2 
No formal Data Monitoring Committee will be established for this study.  Prior to each dose-
escalation step in Part 1, all available data will be reviewed to determine if the next dose 
should be assessed or if the study should be stopped.  If the study proceeds to Part 2, the 
determination of doses to evaluate will be based on an unmasked review of all available data 
from Part 1. 
All decisions to proceed or stop the study at any time will be made by a committee 
comprised of the Medical Monitor, the Head of Clinical and the Chief Executive Officer.  
Dose selection to be studied in Part 2 will be made by the same committee:  an unmasked 
review of all Part 1 safety, tolerability and IOP effect results will be performed to determine 
if Part 2 should be performed and if yes, which dose(s) should be assessed.  All decisions will 
be documented.   
4. 
Study Population  
Prospective approval of protocol deviations to recruitment and enrollment criteria, also 
known as protocol waivers or exemptions, is not permitted. 
The study population consists of adult subjects with POAG or OHT (but who are otherwise 
healthy).  Subject eligibility will be based on the entry criteria below.  
4.1.

4.3. 
Lifestyle Considerations 
During the study, subjects will be advised to: 
• Refrain from activities that may cause irritation to the eye (eg, swimming or smoking); 

Whitecap Biosciences 
Confidential 
 Protocol WB007-001_05 
 
25 
2021.01.30 
• Refrain from engaging in strenuous physical activities/exercise within 24 hours prior to a 
study visit or changing established exercise routine during the study; subjects may 
participate in light recreational activities during the study (eg, watching television, 
reading); 
• Refrain from use of types of medications listed in exclusion criteria.  If used, document, 
in subject’s Source Document /Case Report Form; 
• Refrain from drinking more than ½ cup of liquid for one hour prior to IOP measurements 
on study visit days. 
4.4. 
Screen Failures 
Screen failures are defined as subjects who consent to participate in the clinical study but are 
not subsequently entered into the study.  A minimal set of screen failure information is 
required to ensure transparent reporting of screen failure subjects to meet the Consolidated 
Standards of Reporting Trials (CONSORT) publishing requirements and to respond to 
queries from regulatory authorities. Minimal information includes demography, screen 
failure reasons, eligibility criteria, and any serious adverse event (SAE). 
Individuals who do not meet certain eligibility criteria (eg, IOP) for participation in this study 
(screen failure) may be re-screened once.  Each case must be discussed with Whitecap 
Biosciences for re-screening consideration.  Re-screened subjects should be assigned the 
same participant number as for the initial screening. 
4.5. 
Rationale for Inclusion and Exclusion Criteria  
The inclusion criteria and exclusion criteria [11-17] are designed to enroll adult subjects with 
OHT or mild POAG, as these subjects will be unlikely to require other treatment 
interventions during the study. 
Exclusion criteria [18-26] are designed to exclude subjects whose study results could 
interfere with the interpretation of the efficacy results. Exclusion criteria [29-38] are designed 
to avoid including subjects with ocular conditions that may interfere with the interpretation 
of the study results.

the night before a study visit. 
5.2.2. 
Treatment Compliance  
The IP must be dispensed/ administered only to the study subject by appropriately qualified 
site personnel.  The IP is to be used in accordance with the protocol for subjects who are 
under the direct supervision of an investigator. 
Part 1:  The study treatment will be administered by site personnel.   
Part 2:  Subjects will be instructed on proper dosing techniques and site personnel will 
periodically remind subjects to take their treatments (via text message or phone call), 
(at a minimum, the night before a scheduled follow-up visit). 
6. 
Concomitant Treatments and Medications 
Any medication or vaccine (including over-the-counter or prescription medicines, vitamins, 
and/or herbal supplements) that the subject is receiving after study treatment dosing is 
initiated must be recorded along with: 
• Reason for use; 
• Dates of administration including start and end dates; 
• Dosage information including dose and frequency. 
The Medical Monitor should be contacted if there are any questions regarding concomitant 
treatments and medications. 
6.1. 
Prohibited Treatments and Medications 
The decision to administer a prohibited treatment and/or medication is done with the safety 
of the study participant as the primary consideration.  When possible, Whitecap Biosciences 
should be notified before the prohibited treatment or medication is administered. 
The following medications, classes of medications, and treatment procedures are not 
permitted as concurrent therapy during the study: 
• Medication, conditions, or treatments that are contraindicated to brimonidine;  
• Treatment with any alpha agonists, alpha antagonists (including medications for benign 
prostate hyperplasia), anticholinergics, sedative medications (including antihistamines, 
benzodiazepines, or opiate-type medications), or cold medications;

• Use of adrenergic augmenting antidepressant drugs, MAOIs, SNRIs, or TCAs, or drugs;  
• Use of oral, intramuscular, intravenous, intravitreal, periocular, or topical ophthalmic 
corticosteroids.  NOTE:  intra-articular, inhaled, nasal, and dermal corticosteroids are 
permitted; 
• Use of sedative-hypnotics or other agents (including over the counter) for insomnia; 
• Use of any other ophthalmic topical medications or oral medications for ophthalmic 
indications.  NOTE: artificial tears are allowed during study (see Section 6.3 for 
acceptable usage); 
• Excessive consumption of alcohol or caffeine; 
• Wearing of contact lenses. 
6.2. 
Washout/Waiting Period 
The washout/waiting period between Screening and Baseline is 4 to 50 days.  The duration of 
this period is dependent upon whether a subject is taking IOP-lowering medications at 
Screening. 
6.2.1. 
Washout Period  
Eligible subjects who are being treated with IOP-lowering medication(s) in either eye will 
begin washout of these medication(s) following the screening visit.  The minimum washout 
period will be 4 days to 6 weeks depending on the washout schedule below (Table 5).  Note:  
The time from Screening to Baseline should not exceed 50 days.

6.2.2. 
Considerations During Washout Period 
For a subject on IOP-lowering medication(s), to minimize the effect of the absence of IOP-
lowering therapy during the washout period, the investigator (at his/her discretion) may 
choose to modify a subject’s medication regimen to a medication with a shorter washout 
duration rather than stop all IOP-lowering medications at once (eg, while undergoing the 
washout of a prostaglandin analog [PGA] (6 weeks), a subject may be switched to a carbonic 
anhydrase inhibitor which has shorter washout duration (4 days) than the PGA).  The 
duration of the washout period must adhere to the requirements summarized in Table 5 based 
on the medications used at the time of Screening.  At the discretion of the investigator, for 
subjects undergoing a washout period, consideration should be given to interim safety 
evaluation of IOP at some time during the washout period. 
6.2.3. 
Waiting Period 
Subjects who are not taking any IOP-lowering medications at Screening must have a 
minimum of 3 days between the Screening and Baseline visits.  If a subject has taken 
IOP-lowering medications prior to the screening visit, then s/he must also adhere to the 
appropriate washout period (See Table 5). 
6.3. 
Permissible Medications and Treatments  
During the study, therapy considered necessary for the subject's welfare may be given at the 
discretion of the investigator.  If the permissibility of a specific medication/treatment is in 
question, please contact the Medical Safety Physician.   
Use of intra-articular, inhaled, nasal, and dermal corticosteroids are permitted. 
Use of artificial tears is permitted providing the artificial tear is not given within 30 minutes 
pre- or post-study treatment administration.  Use of artificial tears will be documented in the 
appropriate eCRF. 
Existing use of chronic systemic medications that may have a substantial effect on IOP (eg, 
systemic beta-blockers, carbonic anhydrase inhibitors cholinergic agonists) are allowed 
providing the dosage has been stable for at least 3 months prior to randomization and remains 
stable throughout the study.

Pregnancy and Contraception Considerations 
Definition of Female of Child-bearing Potential  
For purposes of this study, a female will be considered of childbearing potential unless she is 
permanently sterilized (ie, hysterectomy) or is naturally postmenopausal.  Natural menopause 
is defined as the permanent cessation of menstrual periods, determined retrospectively after a 
woman who is at least 40 years of age has experienced 12 months or more of amenorrhea 
without any other obvious pathological or physiological cause.  Female subjects who have 
had a hysterectomy or are naturally postmenopausal will not be required to perform a urine 
pregnancy test or to use contraceptives during the study. 
6.4.1. 
Pregnancy Considerations 
All female subjects who are of child-bearing potential will be advised to avoid pregnancy and 
are required to use methods of contraception considered acceptable to Whitecap Biosciences 
during the study.   
 For information about pregnancy reporting procedures, see Section 6.4.3. 
6.4.2. 
Acceptable Contraception 
The investigator will review the contraception requirements for the study with each subject.  
The following methods of contraception, if properly used, are considered acceptable for use 
to avoid pregnancy during this study:  hormonal contraceptives for females, (ie, oral, patch, 
injection, implant); sterilization (ie, bilateral salpingectomy, bilateral tubal ligation, 
vasectomy with the appropriate post-vasectomy documentation of the absence of sperm in 
the ejaculate); intrauterine devices/systems, sexual abstinence (when this is the lifestyle of 
the subject), and the following barrier methods (male condom with intravaginal spermicide, 
diaphragm or cervical cap with spermicide, vaginal contraceptive ring).  Note: spermicide 
alone is not an acceptable barrier method. 
6.4.3. 
Procedures for Pregnancy Follow-up and Reporting  
If a female subject becomes pregnant during the study (or within 30 days post-study exit), the 
investigator will notify Whitecap Biosciences (or designee) immediately after the pregnancy 
is confirmed.  The subject should not receive further study treatment and she must be exited 
from the study (see Section 8.9 for Early Study Exit Procedures).   
The investigator will (1) notify the subject’s physician that the subject was enrolled in the 
study and treated with an investigational drug AGN-227535 ophthalmic solution or with 
timolol ophthalmic solution, and (2) follow the progress of the pregnancy to term.  The 

Whitecap Biosciences

condition of the conjunctiva, cornea, anterior chamber, iris/pupil, and lens.   The lens will 
also be evaluated following dilation for the cataract assessment; 
• Visual Field Examinations:  Visual field examinations (including historical tests used 
for screening) will be performed using Humphrey automated perimetry.  Acceptable test 
methods are the Humphrey 24-2 full-threshold or Swedish Interactive Threshold 
Algorithm (SITA) Standard tests.  The same test methodology will be used for all study-
related examinations for a given subject; 
• Dilated fundus exam:  Stereoscopic fundus assessments should be conducted through a 
dilated pupil.  The examination will include evaluation of the macula, optic nerve, 
vitreous, and retina.  The cup/disc (C/D) ratio will also be assessed using the Armaly 
Cup-Disc grading card.

of each part of the study; detailed laboratory data will not be captured in EDC. 
8. 
Study Conduct 
This section provides a high-level summary of when during the study the procedures are to 
be performed.  Detailed information on the examination procedures, equipment, and 
techniques is presented in Attachment 12.2.  The procedures should be performed in the order 
as listed on the Schedule of Visits and Procedures (see Tables 1, 2 and 3).  The order of the 
following procedures (Medical and ophthalmic histories, Prior medications/treatments, 
concomitant medications/treatments) can be completed at any time during the study visit.  
For a glossary of terms and abbreviations, see Table 7; for a glossary of subject status 
definitions and other definitions, see Table 8.  For a list of other study supplies besides the IP, 
see Attachment 12.3. 
This study consists of the following scheduled visits: 
• Part 1 (4 visits):  Screening (Days -50 to -4); Baseline (Day -1); Days 1, 2/Exit; 
• Part 2 (5 visits):  Screening (Days -50 to -4); Baseline (Day -1); Days 1, 4, 14/Exit; 
designated site personnel will phone the subject on the evenings before Days 4 and 
14/Exit to remind subjects of dosing requirements (See Section 8.4.2 for details). 
Several visits (Part 1:  Baseline [Day -1], Day 1; Part 2:  Baseline [Day -1], Day 4, Day 
14/Exit) will consist of an 8-hour diurnal assessment. 
The following subsections provide details on the conduct of the study and list of procedures 
for each scheduled visit. Listed ocular procedures should be performed on both eyes.  The 
procedures are listed in the order in which they should be performed (unless otherwise 
specified. 
The Screening visit will occur between 4 and 50 days prior to Baseline (Day -1).  Final 
subject qualification for the study will be determined at Baseline (Day -1).  Subjects who 
qualify for the study will be considered eligible for study treatment administration and be 
assigned to one of the cohorts in a sequential manner (Part 1) or randomly assigned to one of 
the treatment groups (Part 2).

2021.01.30 
To minimize diurnal variation across study visits, particularly for IOP, the time of 
examinations for each subject’s post-screening study-related activities and examinations 
should remain consistent over the course of the study.  IOP measurements should be 
performed at approximately the same time each day based on the time of day established at 
the corresponding Baseline visit.  Hour 0 should occur between 0700 and 0900 hours.  At the 
Baseline visit, IOP measurements should occur 2, 4 and 8 hours from the time of the Hour 0 
IOP evaluation.  At post-Baseline visits, IOP measurements should be obtained as close as 
possible to the same time of day as the corresponding timepoint at Baseline. 
Evaluations should be performed in the order listed in the Schedule of Visits and Procedures 
(see Tables 1, 2 and 3).  Evaluations should be performed by the same evaluator throughout 
the study whenever possible.  If it is not possible to use the same evaluator to follow the 
subject, then evaluations should overlap (ie, examine the subject together and discuss 
findings) for at least one visit. 
If a female becomes pregnant during the study, the investigator will notify Whitecap 
Biosciences immediately after the pregnancy is confirmed and the subject will stop taking 
study treatment.  The subject will be discontinued from the study after appropriate safety 
follow-up. See Section 6.4.3 for Procedures for Pregnancy Follow-up and Reporting. 
8.1. 
Informed Consent  
The study will be discussed with potential subjects.  Those who are interested must give 
written informed consent prior to being subjected to any study-related procedures.  Written 
documentation will be obtained in accordance with relevant country requirements (ie, Written 
Authorization for Use and Release of Health and Research Study Information and local 
privacy requirements, where applicable.  See Section 10.1.3 for details on the Informed 
Consent process. 
After obtaining consent and authorization, potential subjects will undergo a series of 
preliminary screening procedures to assess qualification for the study.  At Screening, each 
subject will be assigned a subject number. 
8.2. 
Subject Screening Visit /Screening Period (Days –50 to –4) 
Subjects who provide informed consent will be assigned a subject identification number that 
will be used on all study documents.  For each subject, the start of the study is defined as the 
time the informed consent is signed.  Study-related procedures and data collection for study 
purposes may commence only after the informed consent has been obtained.  All subjects 
(Part 1 and Part 2) will undergo screening that includes procedures for initial qualification at 

Whitecap Biosciences

 Protocol WB007-001_05 
 
36 
2021.01.30 
the Screening visit followed by a Screening period (washout/waiting period, see Section 6.2) 
for those who meet required Screening visit eligibility criteria (see Sections 4.1 and 4.2 for 
inclusion/exclusion criteria).  For subjects who screen fail, the reason for screen failure, as 
well as demographic and AE data will be collected and reported on the appropriate eCRF. 
Once informed consent has been provided, the following procedures should be performed in 
the order below:  
• Informed consent and authorization; 
• Query to screen for any recent event that could jeopardize the subject’s safety prior to 
further screening; 
• Subject comfort of eye drops evaluation (for IOP-lowering agent(s) subject is taking at 
Screening) (Part 2 only); 
• Medical and ophthalmic histories (including demographic data); 
• Prior medications and treatments (current as well as those that have been stopped within 
3 months prior to the Screening visit); 
• Physical exam (including height and weight); 
• Respiratory rate and temperature (seated); 
• Postural (supine/standing) blood pressure and heart rate; 
• Clinical laboratory evaluation (non-fasting), including CBC with differential, blood 
chemistries and urinalysis.  Note:  The Screening labs will be used to determine subject 
eligibility.  If repeat testing is required, a non-fasting sample should be drawn at least 3 
days prior to the scheduled Baseline visit to ensure results are available for review prior 
to randomization; 
• Macroscopic (gross) hyperemia evaluation; 
• Visual acuity (VA):  Manifest refraction required to obtain a correction for VA evaluation; 
• Slit-Lamp Biomicroscopy;  
• IOP (GAT); 
• Visual field:  May be performed up to 12 months prior to or at Screening using the 
protocol-required testing method.  For subjects requiring pupil dilation, the visual field 
should be performed after the IOP measurement or the next day.  The same test 
methodology should be used throughout the study for a given subject; 
• Fundus exam (including cup/disc ratio, post-pupil dilation); 
• Begin washout of all IOP-lowering medication (see Section 6.2); 
• Enter subject as "in Screening” in eDC; 

Whitecap Biosciences 
Confidential 
 Protocol WB007-001_05 
 
37 
2021.01.30 
• Preliminary determination of eligibility. 
Washout Period (Days –50 to –4) 
Eligible subject who are being treated with IOP-lowering medication(s) in either eye will 
enter the Screening Period and begin washout of these medication(s) following the Screening 
visit.  Details of the washout requirements and options to minimize the absence of treatment 
during washout can be found in Section 6.2 and Table 5.  The Baseline visit will occur 
following the completion of the washout period. 
Waiting Period (Days –4 to –1) 
There is a minimum of 3 days waiting between the Screening and Baseline visits for all 
subjects.  Additionally, for subjects who have taken IOP-lowering medications prior to/at the 
screening visit, then they must also adhere to the appropriate washout period (See Table 5). 
8.3. 
Subject Enrollment – Baseline Visit (Day -1) 
A subject is considered to be enrolled in the study when s/he has completed all screening and 
qualification procedures and meets all eligibility criteria at the Baseline (Day -1) visit based 
on the inclusion/exclusion criteria (see Section 4.1 and 4.2) and confirmed eligibility on the 
morning of Day 1 (Part 1) AND has been randomized at Day 1 (Part 2). 
Baseline - Hour 0: 
• Adverse event (AE) query 
• Medical and ophthalmic histories (including demographic data) 
• Prior medications and treatments (between Screening and Baseline) 
• Concomitant medications and treatments 
• Respiratory rate and temperature (seated) 
• Postural (supine) blood pressure and heart rate  
• 12 lead-ECG 
• Urine Pregnancy Test - Results of pregnancy tests (required for female subjects of 
childbearing potential only) must be obtained prior to treatment and must be negative for 
the subject to be eligible   
• Macroscopic (gross) hyperemia evaluation 
• Pupil Size using near card (Part 2 only) 
• Visual acuity (VA):  Manifest refraction required to obtain a correction for VA evaluation  
• Contrast Sensitivity (Part 2 only)

8.3.1. 
Procedures Prior to Randomization (Part 2 only) 
At the end of the Screening period, subjects will be assessed at the Baseline (Day -1) visit for 
eligibility.  Qualified subjects will return the morning of Day 1 where eligibility will be 
confirmed.  Eligible subjects may then be randomized. (Note:  Subjects who do not meet 
eligibility criteria at Baseline (Day -1) or confirmation of eligibility on Day 1 before dosing 
occurs will be exited from the study as screen failures).  
Only eligible subjects will be randomized. 
8.3.2. 
Randomization Procedures (Part 2 only) 
Prior to randomization of a subject, the site will be required to enter certain data into eDC. 
For IOP, each of the Baseline (Day -1) IOP measurements (either 2 or 3 per eye per hour) 
will need to be entered into IWRS, within eDC.  These measurements will be used to confirm 
that the subject meets IOP inclusion criterion numbers 3 e and f (see Section 4.1).  For 
confirmed qualified IOP, IWRS will assign a stratification code based on the IOP value(s) 
entered, randomize the subject and assign a study kit number.  The kit number corresponds to 
the assigned study treatment for the subject.  See Study Randomization Procedures in the 
IWRS section of the Study Reference Manual for detailed instructions on randomization 
procedures. 
8.4.

Unscheduled Visits and Associated Procedures 
Additional examinations may be conducted as necessary to ensure the safety and well-being 
of subjects during the study period.  eCRFs should be completed for each unscheduled visit.  
For all parameters not measured, indicate “Not Done”. 
Subjects may experience adverse events that necessitate their returning for unscheduled 
visits.  The adverse event and all required information should be recorded on the appropriate 
eCRF and the subject’s record should include all relevant information.   
8.6. 
Instructions for Subjects  
The principal investigator or designated study personnel will instruct the subject on proper 
dosing techniques prior to dispensing the study treatment to the subject.  The sites will 
contact subjects routinely to remind them to administer their study treatment as instructed.  

Whitecap Biosciences 
Confidential 
 Protocol WB007-001_05 
 
43 
2021.01.30 
After each subject has signed the informed consent, s/he will be instructed as follows:  
• To provide a list of all medications (prescription, non-prescription, vitamins, herbal 
supplements), taken within the 3 months prior to Screening and those that will be 
continued during the study period, including the dose and the reason for taking the 
medication and a list of any non-medicinal treatments; 
• At Screening, subjects whose IOP is currently being treated with IOP-lowering 
medication(s) will be instructed by the site to stop taking the IOP-lowering meds 
(ie, begin the washout period) following the Screening visit.  The washout period will be 
a minimum of 4 days to 6 weeks depending on the schedule in Table 5.  Subjects may be 
instructed to return for a visit during the washout period so that the investigator may 
assess their IOP; 
• To return to the study site, at approximately the same time of day established at Baseline 
(Day -1); 
• To remain at the site to complete the remainder of the day’s study-related procedures as 
explained to them by the study site personnel; 
• To refrain from swimming and smoking, being exposed to smoke or other exposure that 
might cause eye irritation during the study; 
• To refrain from drinking more than ½ cup of liquid within 1 hour prior to IOP 
measurement; 
• To avoid discussing side effects (if any experienced) with other subjects in the trial; 
• If spectacles are worn for vision correction, subjects should remember to bring the 
spectacles each time they visit the doctor’s office; 
• Females of childbearing potential should be reminded that they are to maintain the agreed 
to contraception method throughout the study and notify the site in the event of a 
pregnancy, up to 30 days after exiting from the study (see Section 6.4.3); 
• Subjects should also be reminded to contact the study site if they are experiencing any 
difficulties during their study participation. 

Whitecap Biosciences 
Confidential 
 Protocol WB007-001_05 
 
44 
2021.01.30 
In Part 2 only, subjects will also be instructed as follows: 
• On proper dosing of ocular medications and to dose study medication as directed:  
administer one drop in each eye each evening (between 1900 and 2100 hours) starting the 
evening of Day 1 and each morning (between 0700 and 0900 hours) through the evening 
of Day 13. The final dose of study medication on the morning of Day 14/Exit will be 
administered by site personnel after the Hour 0 examination.  Subjects will be reminded 
to take their study medications approximately 12 hours before their Hour 0 appointments 
the evening prior to a post-baseline study visit and to not dose in the morning of Days 4 
and 14.  If desired, subjects will also be given the option for periodic (eg, daily) 
reminders from the Site to take their study medications each morning and evening; 
• On proper storage conditions for study medications.  The study medications should be 
kept in their unit carton (box).  Do not show the bottles to other subjects or study staff 
(except the individual who dispenses the study medication to the subject).  The study 
medications may be stored at room temperature during the study period (between 59°F 
and 77°F); 
• To bring all used and unused study medication to all visits and to remind subjects that all 
study medications will be collected by the site at the Day 14/Exit visit. 
8.7. 
Safety Monitoring  
Investigators are responsible for identifying, monitoring and reporting adverse events that 
occur throughout the study (from subject signing of informed consent through study exit).  
Any adverse event that is marked ‘ongoing’ at the exit visit should be followed-up as 
appropriate until the event is resolved or deemed chronic or stable by the Study Investigator.  
8.7.1. 
Procedures for Collecting and Reporting Adverse Events 
Adverse events will be assessed, documented, and recorded in the eCRF throughout the study 
(ie, after informed consent has been obtained).  At each visit, the investigator will begin by 
querying for adverse events by asking each subject a general, non-directed question such as 
“How have you been feeling since the last visit?”  Directed questioning and examination will 
then be done as appropriate.  All reported adverse events will be documented on the 
appropriate eCRF. 
If, after obtaining the subject’s informed consent but prior to administration of study 
product/treatment, a medical condition is identified via a study entry protocol assessment or 
procedure (eg, screening ECG test) which, based on the Investigator’s judgment (and in 
consultation with the subject), is determined to be a pre-existing condition (ie, a condition 
existing prior to the time of the subject’s informed consent), it should be documented on the 

Whitecap Biosciences 
Confidential 
 Protocol WB007-001_05 
 
45 
2021.01.30 
appropriate eCRF.  Otherwise, the condition should be reported as a pre-treatment adverse 
event.  
All adverse events that are drug-related and unexpected (not listed as treatment-related in the 
current Investigator's Brochure) must be reported to the governing Institutional Review 
Board/Independent Ethics Committee (IRB/IEC) as required by the IRB/IEC, local 
regulations, and the governing health authorities.   
8.7.2. 
Severity 
A clinical determination will be made of the intensity of an AE.  The severity assessment for 
an AE must be completed using the following definitions as guidelines: 
Mild 
Awareness of signs or symptoms, but easily tolerated 
Moderate 
Discomfort enough to cause interference with usual activity 
Severe 
Incapacitating with inability to work or do usual activity 
Not Applicable 
In some cases, an AE may be an ‘all or nothing’ finding that cannot be 
graded (eg, death) 
8.7.3. 
Relationship to Study Drug or Study Procedure 
A determination will be made of the relationship (if any) between an AE and the study drug 
or study procedure, as applicable.  A causal relationship is present if a determination is made 
that there is a reasonable possibility that the AE may have been caused by the study drug or 
study procedure. 
8.7.4. 
Procedures for Reporting a Serious Adverse Event 
Any serious adverse event must be immediately reported but no later than 24 hours after 
learning of the serious adverse event. The first report should be submitted even if the 
available information is minimal.  All subjects with a serious adverse event must be followed 
up and the outcomes reported.  The investigator must supply Whitecap Biosciences and the 
IRB/IEC with any additional requested information (eg, autopsy reports, discharge 
summaries).   
In the event of a serious adverse event, the investigator must: 
1. Notify Whitecap Biosciences (or designee) immediately by email using the Serious 
Adverse Event Form; phone numbers and relevant Whitecap Biosciences (or designee) 
personnel contacts are on the front page of this protocol. 

Whitecap Biosciences 
Confidential 
 Protocol WB007-001_05 
 
46 
2021.01.30 
2. Obtain and maintain in his/her files all pertinent medical records, information, and 
medical judgments from colleagues who assisted in the treatment and follow-up of the 
subject. 
3. Provide Whitecap Biosciences (or designee) with a complete, written description of the 
adverse event(s) on the Serious Adverse Event Form describing the event 
chronologically, including any treatment given (eg, medications administered, other 
treatments given) for the adverse event(s).  Summarize relevant clinical information 
about the event:  signs, symptoms, diagnosis, clinical course and relevant clinical 
laboratory tests, etc.  Include any additional or alternative explanation(s) for the 
causality which includes a statement as to whether the event was or was not related to 
the use of the investigational drug. 
4. Provide follow-up SAE reports to Whitecap Biosciences (or designee) as more 
information becomes available 
5. Promptly inform the governing IRB/IEC of the serious adverse event as required by the 
IRB/IEC, local regulations, and the governing health authorities. 
See Study Reference Manual for additional details. 
8.8. 
Procedures for Stopping Study Treatment  
Part 1- There are no specific procedures for stopping treatment. 
Part 2 - When the study treatment is stopped for an individual subject prior to the protocol 
defined duration for study treatment administration, the Day 14/Exit (Hour 0) procedures, at 
a minimum should be performed.  The reason that the study treatment is stopped should be 
documented on the appropriate eCRF. 
8.9. 
Early Study Exit Procedures 
8.9.1. 
Subject Discontinuation/Withdrawal from the Study 
• A subject may withdraw from the study at any time at his/her own request, or may be 
withdrawn at any time at the discretion of the investigator for safety, behavioral, 
compliance, or administrative reasons;   
• If the subject withdraws consent for disclosure of future information, the sponsor may 
retain and continue to use any data collected before such a withdrawal of consent; 
• If a subject withdraws from the study, he/she may request destruction of any samples 
taken and not tested, and the investigator must document this in the site study records; 
• A subject who is enrolled, but who had significant deviation from protocol-specified 
inclusion/exclusion criteria, may be discontinued from participation in the study; 

Whitecap Biosciences 
Confidential 
 Protocol WB007-001_05 
 
47 
2021.01.30 
• If a female becomes pregnant during the study, the investigator will notify Whitecap 
Biosciences immediately after the pregnancy is confirmed and the subject will stop taking 
study treatment.  The subject will be discontinued from the study after appropriate safety 
follow-up. See Section 6.4.3 for Procedures for Pregnancy Follow-up and Reporting; 
• Subjects who are exited before completing the study may be replaced. 
See Schedule of Visits and Procedures for specific data to be collected at the time of study 
discontinuation and follow-up and for any further evaluations that need to be completed.  If a 
subject is discontinued prior to completing the study, the procedures outlined for the Day 
2/Exit visit (for Part 1) or the Day 14/Exit visit (Hour 0 timepoint at a minimum) for Part 2 
should be performed at the last visit attended. 
When a subject exits before completing the study, the reason for the early exit will be clearly 
documented on the appropriate eCRF. 
If the subject exits before completing the study, any serious adverse events or treatment-
related non-serious adverse events occurring within 14 days after the last dose of study 
treatment should be reported to the Site.   
8.9.2. 
Lost to Follow Up 
A participant will be considered lost to follow-up if he or she repeatedly fails to return for 
scheduled visits and is unable to be contacted by the study site.  
The following actions must be taken if a participant fails to return to the clinic for a required 
study visit: 
• The site must attempt to contact the participant and reschedule the missed visit as soon as 
possible and counsel the participant on the importance of maintaining the assigned visit 
schedule and ascertain whether or not the participant wishes to and/or should continue in 
the study; 
• Before a participant is deemed lost to follow up, the investigator or designee must make 
every effort to regain contact with the participant (where possible, 3 telephone calls and, 
if necessary, a certified letter to the participant’s last known mailing address or local 
equivalent methods). These contact attempts should be documented in the participant’s 
medical record; 
• Should the participant continue to be unreachable, he/she will be considered to be lost to 
follow up and exited from the study;  
• When a subject is lost to follow-up, the reason for the early exit will be clearly 
documented on the appropriate eCRF.

2021.01.30 
8.10. 
Procedures for Unmasking of Study Medication 
When necessary for the safety and proper treatment of the subject, the investigator can 
unmask the subject’s treatment assignment to determine which treatment has been assigned 
and institute appropriate follow-up care.  When possible, Whitecap Biosciences (or designee) 
should be notified prior to unmasking study medication.  The investigator should inform 
Whitecap Biosciences (or designee) of the unmasking if there is no notification prior to the 
unmasking.  
The treatment assignment for the subject can be determined by designated site personnel 
through the IWRS via password protected access.  The reason for breaking the code must be 
recorded in the subject’s source documents.  See Study Reference Manual for additional 
details. 
9. 
Statistical Procedures 
One database lock will occur when all subjects (both Part 1 and Part 2) have either completed 
the study or discontinued from the study prematurely, and all data queries have been 
resolved.  Randomization release will occur following the database lock.  A detailed 
statistical analysis plan (SAP) will be approved prior to database lock.  
9.1. 
Analysis Population(s) 
Each population will be analyzed based on the treatment received. 
Part 1:  The Safety population consisting of all treated subjects will be used for all analyses. 
Part 2: The following populations will be used for analysis:  
• The Safety population will consist of all treated subjects. All safety analyses will be 
performed using the safety population; 
• The Modified Intent-to-treat (mITT) will consist of all randomized and treated subjects 
who provide IOP data at baseline and at least one post-baseline IOP assessment.  This 
population will be used for analyses of efficacy data; 
• The Per-protocol (PP) population is a subset of the mITT population and will consist of 
subjects who did not have any major protocol violations deemed to have potential impact 
on the primary endpoint.  This population will be used to confirm the primary efficacy 
analysis and will be determined prior to database lock.

9.2. 
Sample Size Calculation 
For each cohort in Part 1 of the study a sample size of 6 patients will provide 83% power to 
detect a 3 mmHg within-group change from pre-dose assuming a standard deviation of 2 and 
two-sided alpha = 0.05, based on a one-sample t-test.  With larger standard deviations (≥2.5) 
the power to detect this difference is <66%. 
For Part 2, a sample size of 24 has > 90% power to detect a within-group mean changes from 
baseline IOP of 3 mm Hg, assuming a SD of 2.5 mm Hg.  Also, power calculations were 
performed for the comparison of each dose of AGN–227535 versus Timolol.  These 
calculations consider treatment differences (AGN–227535 minus Timolol) mean changes 
from baseline in study eye IOP in the mITT population at Day 14/Exit.  
The power to detect treatment group differences from -1 to -4 mm Hg with common standard 
deviations (SDs) ranging from 2.5 to 3.5, based on a two-sample t-test are shown in Table 6.

Additional sample size calculations were performed for tests of non-inferiority of either dose 
of AGN-227535 to Timolol.  These calculations considered a non-inferiority margin of 1.5 
mm Hg and one-sided α = 0.025.   With a treatment group difference of -1 mm Hg, the power 
ranged from 50% for a common SD of 3.5 to 78% for a common SD of 2.5. 
The calculation was based on the non-inferiority tests for the difference between two means 
using t-test as implemented in the commercial software PASS version 16.0.3 (2018).

Methods of Analyses 
In general, data will be summarized with descriptive statistics which will include sample 
size, mean, standard deviation, median, minimum and maximum for continuous variables 
and frequency and percentage for categorical variables.   
Part 1: All safety and IOP-lowering effects tabulations will provide descriptive statistics by 
cohort. 
Part 2: For continuous variables, treatment groups will be compared using analysis of 
variance covariance techniques or two-sample t-tests.  Nominal variables will be 
analyzed using Pearson's chi-square test or Fisher's exact test.  
Analyses performed for the mITT population will use the method of last observation carried 
forward (LOCF) to impute missing values.  No imputation for missing data will be 
performed for the PP or safety populations.   
As this is an exploratory trial, all treatment comparisons will be made at the two-sided α = 
0.05 level without adjustment for multiple comparisons.  
9.3.1 
Efficacy (Part 2) 
9.3.1.1. 
Primary Efficacy Endpoint(s) 
The primary response measure is IOP.  Two consecutive measurements of IOP will be taken 
for each eye, with the right eye measured first.  If the first two measurements of either eye 
differ by more than two mm Hg, a third measurement will be taken for the eye.  Depending 
on the number of measurements required and obtained, the IOP for a given eye will be 
represented by either the average or the median of the readings.  Details will be provided in 
the SAP.  
The change from baseline for each eye at each post-baseline assessment is calculated as the 
IOP at that assessment minus the IOP at the corresponding hour at baseline.  Efficacy will be 
evaluated in the study eye. The study eye is the eye that meets the inclusion/exclusion 
criteria.  If both eyes meet the criteria, the study eye will be the eye with the worse (highest) 
IOP at Day -1 Hour 0.  If both eyes have the same IOP value at this timepoint, the right eye 
will be the study eye. 
The primary efficacy endpoints are the Day 14/Exit mean IOP changes from Baseline (Day -
1) at each time-matched hour (0, 2, 4, 8). The primary hypothesis is that AGN-227535 
ophthalmic solution effectively lowers IOP.  The primary efficacy analysis is the within-

 Protocol WB007-001_05 
 
51 
2021.01.30 
group mean change from baseline at Hour 2, the time of peak efficacy of timolol.  This study 
will also assess if AGN-227535 is non-inferior to Timolol ophthalmic solution 0.5% with 
respect to change from baseline (follow-up minus baseline) in study eye IOP at each time-
matched hour evaluated (hours 0, 2 4, and 8) at Day 14/Exit in the mITT population.  The 
analyses will be performed via analysis of covariance (ANCOVA) which will have treatment 
as the main effect and the Baseline hour-matched IOP as the covariate in the model.  
Pairwise treatment group comparisons will be performed for each individual dose of AGN-
227535 versus timolol ophthalmic solution 0.5%. A 2-sided 95% confidence interval (CI) for 
the treatment difference (AGN-227535 Ophthalmic Solution minus Timolol ophthalmic 
solution 0.5%) will be constructed based on this ANOVA model for each AGN-227535 dose.  
AGN-227535 ophthalmic solution will be considered to be non-inferior to Timolol 
ophthalmic solution 0.5% if the upper limit of the 95% CI does not exceed 1.5 mmHg at the 
majority of timepoints evaluated (ie, 3/4) at the Day 14/Exit visit.  If AGN-227535 
ophthalmic solution is determined to be non-inferior to Timolol ophthalmic solution 0.5%, a 
further attempt to show superiority of AGN-227535 over Timolol will be made.   
Primary efficacy will be evaluated in the mITT population.  
9.3.1.2. 
Secondary Efficacy Endpoint(s) 
Mean IOP at Day 14/Exit. 
Mean IOP change from baseline at each time-matched hour via analysis of variance 
(ANOVA) which will have treatment and the Baseline IOP stratum (IOP ≤25 mm Hg and > 
25 mm Hg as the main effects in the model. 
9.3.2. 
 
Safety Analyses 
All safety analyses will be performed on the Safety Population. 
The Medical Dictionary for Regulatory Activities (MedDRA) nomenclature will be used to 
code adverse events. A detailed definition of treatment emergent adverse events (TEAEs) will 
be provided in the SAP. The number and percent of subjects with adverse event reports will 
be tabulated for all treatment emergent adverse events (TEAEs) regardless of causality, 
treatment-related TEAEs, all serious TEAEs, treatment-related serious TEAEs, and all 
adverse events leading to premature discontinuation of study treatment.  
For Part 2, analyses of macroscopic hyperemia and hyperemia as evaluated on 
biomicroscopy will include evaluation of peak severity at each post-baseline visit (Days 4 
and 14) and across all post-baseline time points.

9.4. 
Other Analyses 
The primary analysis (see Section 9.3.1.1) will be performed for the PP population. 
Additional planned analyses include treatment comparisons of: 
• Mean diurnal IOP (average of IOP measurements taken throughout the day) change from 
baseline.  The same methods as described in Section 9.3.1.1 will be used; 
• IOP values at each scheduled hour of Day 14/Exit.  Analyses will be performed using an 
ANCOVA model with treatment as the main effect and baseline IOP hour-matched IOP as 
the covariate;  
• Mean diurnal IOP at Day 14/Exit. Analyses will be performed using a two-way ANCOVA 
model with treatment as the main effect and baseline mean diurnal IOP as the covariate. 
Additional exploratory analyses may be described in the SAP.  
9.5. 
Subgroup Analyses 
For Part 2, descriptive statistics for the primary analyses will be provided by Baseline IOP 
stratum. Additional subgroup analyses may be specified in the SAP.

12.2. 
Examination Procedures, Tests, Equipment, and Techniques  
Study evaluations should be performed by the same investigator or sub-investigator 
throughout the study whenever possible.  If it is not possible to use the same individual to 
follow the subject, then an attempt should be made to have visits overlap (examine the 
subject together and discuss findings) for at least one visit.  At designated study visits, 
physical examinations and the comfort of eye drop subject questionnaire should be conducted 
prior to other assessments or invasive procedures.  Data will be recorded on the appropriate 
eCRF. 
12.2.1. 
Demographics and Baseline Characteristics 
Demographic information including age, race (including limited ethnicity), gender and iris 
color are to be obtained at the screening visit. 
12.2.1.1. Medical and Ophthalmic Histories and Procedures 
Medical (relevant) and ophthalmic history (including the history of the current 
disease/disorder), any pertinent procedures that could potentially influence the safety of the 
subject and/or the outcome of the study and any information regarding underlying 
disease/disorders are to be obtained at Screening.  Data will be recorded on the appropriate 
eCRF.   
12.2.1.2. Physical Examination (Including Height and Weight) 
The subject will be examined for any detectable abnormalities of the following body 
systems:  general appearance; head, eyes, ears, nose and throat (HEENT); 
heart/cardiovascular; lungs; abdomen; neurologic; extremities; back; musculoskeletal; 
lymphatic and skin. 
Height will be measured (without shoes) in inches (in) or centimeters (cm).  Weight (without 
shoes) will be measured in pounds (lb) or kilograms (kg) using a scale.  Historical subject 
information and/or subject reports should not be used for the height and weight 
measurements. 
12.2.1.3. Respiratory Rate and Temperature 
Respiration rate will be measured after the subject has been in a resting state (seated) for at 
least 5 minutes.  Respiration rate will be counted for 30 seconds, multiplied by 2, and 
recorded as breaths per minute.  Temperature will be measured after the subject has been in 
a resting state (seated) for at least 5 minutes.  Temperature will be measured in Celsius (°C) 
or Fahrenheit (°F).  Oral, Skin or tympanic temperature methods of collection are acceptable.

12.2.1.4. Postural (Supine / Standing) Blood Pressure and Heart Rate  
Postural Systolic/diastolic blood pressure and heart rate will be measured after the subject 
has been in a resting state (supine) for at least 5 minutes and then again 3 minutes after 
standing.  Record the 2 measurements from the 2 positions (supine and standing).  Pulse will 
be counted for 30 seconds, multiplied by 2, and recorded in bpm. 
12.2.1.5. Urine Pregnancy Test 
Female subjects who are of child-bearing potential (see Section 6.4 for definition) will have a 
urine pregnancy test performed.  Pregnancy test kits will be provided by a qualified third-
party vendor (see Attachment 12.4) and will be administered according to the instructions 
provided with the tests. 
12.2.1.6. 12 lead-ECG 
Sites will receive training on the use of ECG equipment provided.   
[Triplicate] 12-lead ECG will be obtained using an ECG machine that automatically 
calculates the heart rate and measures PR, QRS, QT, and [QTc] intervals.  At each time point, 
3 individual ECG tracings should be obtained as closely as possible in succession, but no 
more than 2 minutes apart. The full set of triplicates should be completed in less than 4 
minutes.  
12.2.1.7. Clinical Safety Laboratory Assessments (non-fasting) 
The investigator must review the laboratory report, document this review, and record any 
clinically relevant changes occurring during the study in the AE section of the eCRF.  
Clinically significant abnormal laboratory findings are those which are not associated with 
the underlying disease, unless judged by the investigator to be more severe than expected for 
the participant's condition.  The laboratory reports must be filed with the source documents.   
All laboratory tests with values considered clinically significantly abnormal during 
participation in the study or within [insert timeframe] after the last dose of study treatment 
should be repeated until the values return to normal or baseline or are no longer considered 
clinically significant by the investigator or medical monitor. 
• If such values do not return to normal/baseline within a period of time judged reasonable 
by the investigator, the etiology should be identified and the sponsor notified; 
• All protocol-required laboratory assessments (see below) must be conducted in 
accordance with the Laboratory Manual and the Schedule of Visits and Procedures;

12.2.2.1. Subject Comfort of Eye Drops Evaluation (Questionnaire) (Part 2 only) 
Subjects will be asked questions by a designated clinical staff member at the site to assess the 
study medications by responding to a series of questions regarding their comfort of their IOP-
lowering medications.  Conduct these interviews in a quiet place with only the study 
participant and the interviewer present.  Please instruct each subject that his/her input is 
important.  Subjects should report on their experiences and impressions (ie, there are no 
“right” or “wrong” answers).  Begin with asking the subject about all of the symptoms s/he 
may be experiencing or overall comfort in the right eye and then when complete, ask about 
the symptoms of the left eye. 
Subjects will be asked questions by a clinical staff member at the site to assess the comfort of 
their eye drop medication(s) (for each eye): 
• (if applicable) the IOP-lowering medication they are taking prior to entry into the study 
(at Screening); 
• the study medication (at post-Baseline visits). 
Leading Question at Screening:  Thinking about your <appropriate> eye, how would you 
rate the overall comfort of your current glaucoma eye drops? 
Leading Question at Study Visits:  Thinking about your <appropriate> eye, how would you 
rate the overall comfort of the study eye drops? 
Using the Subject Comfort of Eye Drops Questionnaire on a 6-point scale, read to the subject 
each of the responses for the selection that best matches their experience:  Very comfortable, 
Comfortable, Slightly uncomfortable, Uncomfortable, Very Uncomfortable, Intolerable. 
12.2.2.2. Macroscopic Bulbar Conjunctival Hyperemia 
The macroscopic (gross) hyperemia grading should be completed prior to any other eye 
examinations.  Bulbar hyperemia will be graded by the Investigator upon gross inspection 
under consistent illumination by comparing the appearance of the bulbar conjunctiva to 
standard photographs.

12.2.2.3. Visual Acuity 
Manifest refraction will be performed at specified study visits (See the Schedule of Visits and 
Procedures Tables 1, 2, and 3 in the protocol synopsis and see Section 8) to obtain a 
correction for all visual acuity evaluations.  Visual acuity (in Snellen equivalents) will be 
measured for each eye using a logarithmic (LogMar) visual acuity chart for testing at 4 
meters.  Please refer to the Study Reference Manual for details on the procedures for 
measuring visual acuity. 
12.2.2.4. Pupil Size (Part 2 only) 
Pupil size for each eye will be measured using the centimeter ruler on the near card, measure 
the subject's undilated pupils to the nearest 0.5 mm in size.  The pupil gauge on the near card 
may be used instead per investigator preference.  The size of the pupil will be measured prior 
to biomicroscopy and IOP evaluations. 
12.2.2.5. Contrast Sensitivity (Part 2 only) 
Contrast Sensitivity will be measured using the VectorVision CSV-1000 test at four levels of 
contrast.  The test distance for the chart must be kept consistent throughout the study.  Do not 
set up chart in brightly lit room or sunlight.  Details for the operation of the equipment and 
the conduct of the test for each patient can be found in the Study Reference Manual. 
12.2.2.6. Biomicroscopic Examinations

Iris color will be recorded at Screening using the following classification:  blue, blue-gray, 
blue/gray-brown, gray, green, green-brown, hazel, brown, dark brown, or other (specify). 
12.2.2.7. Intraocular Pressure (IOP) (mm Hg)  
IOP should be measured only after the biomicroscopic exam is completed and must be 
measured prior to pupil dilation.  IOP measurements will be taken by two qualified 

Whitecap Biosciences 
Confidential 
 Protocol WB007-001_05 
 
72 
2021.01.30 
independent study site personnel using a Goldmann applanation tonometer (GAT) affixed to 
a slit lamp with the subject seated.  One person will adjust the dial in masked fashion while a 
second person will read and record the value.  The subject and slit lamp should be adjusted so 
that the subject’s head is firmly positioned on the chin rest and against the forehead rest 
without leaning forward or straining.  Tight fitting neckwear should be loosened.  Both eyes 
will be tested, with the right eye preceding the left eye.  Each IOP measurement is to be 
recorded. 
One person (“the measurer”) looks through the binocular viewer of the slit lamp at low 
power.  The tension knob is pre-set at a low-pressure value (4 to 6 mm Hg).  The measurer 
follows the image of the fluorescein-stained semicircles while he/she slowly rotates the 
tension knob until the inner borders of the fluorescein rings touch each other at the midpoint 
of their pulsation in response to the cardiac cycle.  When this image is reached, the measurer 
takes his/her fingers off the tension knob and the second person (“the reader”) records the 
IOP reading along with the date and time of day in the source document, thus maintaining a 
masked IOP reading.  For a given subject, the reader should not also be the person to 
dispense/administer/discuss study medications with the subject. 
At least two, and if necessary, three consecutive measurements will be taken to determine 
IOP in the manner described above.  If the first two measurements differ by 2 mm Hg or less, 
a third measurement is not required, and the two measurements will be recorded.  If the first 
two measurements differ by more than 2 mm Hg, a third measurement should be made, and 
all three measurements will be recorded. 
12.2.2.8. Visual Field 
Measure the subject’s pupils (to the nearest 0.5 mm).  If they are less than 3 mm in diameter, 
dilate them with 2.5% phenylephrine drops, unless contraindicated.  If the brow is heavy or 
the upper lid is drooping, tape accordingly.  Visual field results must be reliable (ie, ≤ 33% 
fixation losses, false positive or false negative errors) or the field should be repeated within 
two weeks.  Visual field examinations will be performed using a Humphrey automated 
perimetry test (24-2) using the full threshold or SITA standard testing method).  The same 
test method (eg, SITA Standard 24-2) should be used for all visual fields for a given subject, 
including the historical visual field, if applicable.  Preferred equipment is the Humphrey 700 
Humphrey Field Analyzer (HFA) 2 series machines (eg, 740 or 750).  Visual fields will be 
reported as normal or abnormal and the mean deviation will also be recorded in decibels 
(dB).

Begin by testing the right eye.  Adjust the chin rest and the table height as needed to achieve 
proper alignment as well as to maintain the subject in a comfortable seated position 
throughout the test.  It is permissible to encourage the subject occasionally if the subject 
seems to be fatigued or losing concentration, and to allow the subject to pause and rest if 
necessary.  The subject should also be informed that a good time to blink is when the 
response button is pushed so as not to affect the results of the test. 
12.2.2.9. Other Ophthalmic Examinations 
Use biomicroscopic examination, indirect lenses, direct/indirect ophthalmoscopy, etc. as 
appropriate to visualize. 
Lens 
Lens Status 
Lens status will be assessed as phakic, pseudophakic, or aphakic.  The lens (including the 
posterior capsule for subjects who have undergone lens extraction) will also be evaluated for 
pathology.  If pathology is present, it will be described. 
Cataract Assessment (phakic eyes only) 
Under dilated examination, the presence and severity of nuclear, cortical and posterior 
subcapsular cataract lens opacities will be evaluated.  At the first dilated examination, each 
type of cataract, if present, will be graded using the scale below.  At the last follow-up dilated 
examination, each type of cataract will be assessed for change from baseline and if changed, 
the current severity will be graded using the scale below:

Revision 
Rationale 
4.1 
Exclusion 15: removed “evidence of unilateral cataract 
surgery” from the criterion.  The criterion now is: 
“Evidence of cataract surgery resulting in complications 
(eg, capsular rupture) in the study eye.” 
Loosened the criterion to 
ensure efficient enrollment of 
the study population without 
jeopardizing the outcome of the 
study.   
4.1 and 8.4.1 
Modified exclusion 27: “Previous participation in this 
study” to “Previous randomization in Part 2 of this 
study”. 
 
Part 1 Day 2 (Hour 0): removed statement not allowing 
participation in Part 2 for subjects who participated in 
Part 1. 
Allow for subjects who 
participated in Part 1of the 
study to participate in Part 2.  A 
subject who participates in both 
Parts 1 and 2 will be counted 
only once in the total number of 
participants of the study.

Amendment 5 Summary 
Study Title:  A Phase 1/2a Assessment of WB007 Ophthalmic Solution in Subjects with 
Primary Open-Angle Glaucoma or Ocular Hypertension 
Protocol WB007-001_05 (Amendment 5);  Date of Amendment:  January 2021 
Section(s) 
Revision 
Rationale 
Synopsis, 3.2.1, 
7.5, 8.3.2, Table 
8, 12.4. 
Further clarified wording on the role of the IWRS for 
selection of study eye.  
IWRS was used to confirm IOP 
eligibility.  Designation of the 
study eye was based on the 
algorithm pre-specified in the 
protocol in Section 9.3.1.1. 
Synopsis, 3, 
9.3.1.1, 
 
Clarified the wording for the primary efficacy analysis.  
The primary efficacy analysis is the within-group mean 
change from baseline at Hour 2, the time of peak efficacy 
of timolol. 
The protocol wording was 
clarified to align with the 
Statistical Analysis Plan (SAP).   
Synopsis, 9.2 
 
 
Clarified the sample size power calculation to include the 
power to detect within-group mean change from baseline 
of at least a 3 mm Hg for the primary endpoint assuming 
a standard deviation of 2.5 with two-sided alpha = 0.05.”  
 
In Section 9.2, deleted the last paragraph and replaced the 
3rd sentence under the table to align with the protocol 
synopsis. 
The protocol wording was 
clarified to align with the SAP.
