Title of Study: A Randomized, Multicenter, Observer-Masked Study to Compare the Safety and 
Efficacy of BTQ-1901-A, BTQ-1901-B, and BTQ-1902 to Timolol 0.5% in Subjects with Primary 
Open Angle Glaucoma or Ocular Hypertension  
Study center(s): Up to 20 sites in the United States 
Studied period (years):  
Estimated date first patient enrolled: September 2020 
Estimated date last patient completed: June 2021 
Phase of development:  
2 
Objectives: To evaluate ocular and systemic safety and the efficacy of BTQ-1901-A,  
BTQ-1901-B, and BTQ-1902 ophthalmic suspensions in comparison to timolol 0.5% ophthalmic 
solution in subjects with primary open-angle glaucoma (POAG) or ocular hypertension (OHT). 
Methodology: This will be a randomized, multicenter, parallel-group, observer-masked study with 
approximately 240 subjects who will be treated for 84 days (12 weeks).  
Adult subjects will have POAG or OHT in both eyes (presence of POAG in one eye and OHT in the 
fellow eye is acceptable) that requires therapy and elevated intraocular pressure (IOP) adequately 
controlled, in the opinion of the Investigator, on no more than 2 ocular hypotensive medications 
(fixed dose combinations count as 2 medications). Subjects with OHT on no ocular hypotensive 
medication are acceptable. If required, subjects will participate in a minimum washout period of 
28 days for prostaglandin analogs, rho-associated protein kinase (ROCK) inhibitors, or beta (β) 
blockers, 14 days for adrenergic agonists, and 5 days for muscarinic agonists or carbonic anhydrase 
inhibitors (CAIs). A mid-washout onsite safety check may be conducted for subjects undergoing a 
28-day washout period, at the Investigator’s discretion. At Visit 3/Qualification/Baseline (Day 1), 
eligible subjects must have unmedicated IOP measurements ≥ 22 and ≤ 34 mm Hg at 8:00 AM and  
≥ 18 and ≤ 34 mm Hg at 10:00 AM and 4:00 PM in the same eye(s) qualifying at the 8:00 AM time 
point. The IOP must be at least 22 mm Hg at each consecutive measurement at the 8 AM time point. 
At Visit 3, IOP will be taken bilaterally at 8:00 AM, 10:00 AM, and 4:00 PM (each ± 30 minutes). 
Even if only one eye meets all inclusion/exclusion criteria, both eyes will be treated.  
Eligible subjects will be randomized in a 1:1:1:1 ratio into 1 of 4 treatment arms and receive 1 drop in 
each eye twice daily (BID), morning and evening, for 84 days: 
• 
BTQ-1901-A (nebivolol 0.5%) ophthalmic suspension (N = 60) 
• 
BTQ-1901-B (nebivolol 1.0%) ophthalmic suspension (N = 60) 
• 
BTQ-1902 (timolol 0.5%) ophthalmic suspension (N = 60) 
• 
Timolol 0.5% ophthalmic solution (N = 60)

Methodology (Continued): 
The study will be observer masked. Randomized study medication will be provided in foil pouches 
contained in identical-appearing boxes. The pouches will contain 5 mL multidose bottles for the 
BTQ-1901-A, BTQ-1901-B, and BTQ-1902 treatment arms and 10 mL multidose bottles for the 
timolol 0.5% treatment arm). An unmasked staff member not involved in performing study  
endpoint-related procedures (i.e., IOP measurement) will be responsible for providing dosing 
instructions, dispensing study medication, and conducting study medication accountability and dosing 
compliance assessment. The identity of the study medications will be masked to the Investigator and 
study personnel responsible for study endpoint-related procedures. Moreover, IOP measurements for 
a given subject should be performed by the same Investigator/designee who will be masked to the 
readout of the tonometer, which will be read and entered into the source documentation (whether 
electronic or paper) by a second staff member once the Investigator/designee reaches the correct 
applanation effect in the slit lamp. 
Study visits will be conducted as follows: Visit 1/Screening/Day -35 to -1, Visit 2/Washout Safety 
Check/Day -14 ± 3 (optional, but conducted at the Investigator’s discretion for subjects undergoing 
28-day washout periods), Visit 3/Qualification/Baseline/Day 1, Visit 4/Day 15 ± 3, 
Visit 5/Day 42 ± 3, and Visit 6/Day 84 ± 3. At Visits 4, 5, and 6, subjects will be evaluated for 
efficacy and safety at 8:00 AM, at 2 hours after study medication dosing at the clinical site 
(~10:00 AM), and at 4:00 PM (each ± 30 minutes). All ophthalmic assessments will be performed 
bilaterally. 
Number of Patients (Planned): The sample size is approximately 60 subjects per group, for a total 
of approximately 240 subjects. 
Inclusion Criteria:  
Individuals must meet the following criteria: 
1. Willing and able to understand and sign an informed consent form prior to any study-related 
procedures. 
2. Able to administer or have a caregiver accurately administer an eye drop. 
3. 18 years of age or older, male, or female. 
4. Have POAG or OHT in both eyes that requires therapy for IOP and is adequately controlled, 
in the opinion of the Investigator, on no more than 2 ocular hypotensive medications (fixed 
dose combinations count as 2 medications). Subjects with OHT on no ocular hypotensive 
medication are acceptable. Presence of POAG in one eye and OHT in the fellow eye is 
acceptable.  
5. Able, in the opinion of the Investigator, to safely discontinue use of ocular hypotensive 
medications, if applicable, and undergo the appropriate required washout period for ocular 
hypotensive medications prior to Visit 3/Qualification/Baseline. 
6. At Visit 3/Qualification/Baseline, at least one eye must have unmedicated (post washout) IOP 
≥ 22 and ≤ 34 mm Hg at 8:00 AM, and ≥ 18 and ≤ 34 mm Hg at 10:00 AM and 4:00 PM (in 
the same eye[s] qualifying at the 8:00 AM time point). The IOP must be at least 22 mm Hg at 
each consecutive measurement at the 8:00 AM time point. 
7. No significant visual field (VF) loss, defined as a mean deviation in either eye greater than 
- 12 dB or a central point of fixation < 5 dB in either eye. If the VF performed at or within 
90 days prior to Visit 1 does not meet study required parameters, it may be repeated (test 
should be prior to randomization at Visit 3/Qualification/Baseline).

Reference Therapy, Dosage and Mode of Administration: 
Timolol 0.5% ophthalmic solution, 1 drop in each eye BID 
Duration of Treatment:  
Twelve (12) weeks (84 days) 
Criteria for Evaluation: 
Efficacy: Efficacy will be assessed in the study eye at each visit by IOP values at each timepoint as 
measured by Goldmann applanation tonometry. 
Safety: Safety will be assessed at each visit by LogMAR VA, slit lamp examination, resting heart rate 
(HR)/blood pressure (BP), and adverse event (AE) collection. Ophthalmoscopy/dilated fundus 
examination and VF testing will occur at Visit 1/Screening and Visit 6/Day 84 (note: VF testing is not 
mandated at Visit 1/Screening if a test meeting the protocol requirements was performed and the 
results were documented within 90 days prior to Visit 1/Screening). 
Safety/Tolerability Assessments: 
Subjective comfort/tolerability data (i.e., rating of drop comfort as assessed by the subject) will be 
collected at Visit 3/Qualification/Baseline (Day 1), and at each post baseline visit. Conjunctival 
hyperemia will be assessed by the Investigator using the McMonnies photographic scale at 
Visit 3/Qualification/Baseline and at each post baseline visit. 
Pharmacokinetics: 
Plasma concentration will be measured in a subset of 40 subjects; blood samples will be collected 
following dosing at Visit 4/Day 15 and Visit 6/Day 84. 
Study Endpoints: 
Primary Efficacy Endpoint: IOP values at each time point (8:00 AM, 2 hours after study medication 
dosing at the clinical site [~10 AM], 4:00 PM) at Visit 4/Day 15, Visit 5/Day 42, and Visit 6/Day 84.  
Secondary Efficacy Endpoints:  
• 
Change from baseline (Visit 3/Qualification/Baseline) in the average of the 3 daily IOP 
measurements at each post baseline visit. 
• 
Time-matched change from baseline (Visit 3/Qualification/Baseline) in IOP measurements at 
all time points at Visit 4/Day 15, Visit 5/Day 42 and Visit 6/Day 84. 
Statistical Methods: 
Primary efficacy analysis will be conducted on the per protocol (PP) population (those subjects in the 
intent to treat [ITT] population who were both randomized and dosed and who had no major protocol 
deviations). Efficacy analyses will also be conducted on the ITT population. Safety analyses will be 
performed using the safety analysis set (all randomized subjects who received at least one dose of the 
allocated study medication). 
The primary efficacy analysis will be the between-group comparison of the mean IOP values in the 
study eye at each time point at each of the Visit 4/Day 15, Visit 5/Day 42, and Visit 6/Day 84 visits 
(ie, a total of 9 between-group comparisons). A hierarchical analysis will be conducted to compare 
each of the investigational products against the comparator, timolol 0.05%, as follows: (1) BTQ-1902, 
(2) BTQ-1901B, and (3) BTQ-1901A. To demonstrate noninferiority, the upper limits of the 2-sided 
95% confidence interval (CI) for the difference between each comparison should be lower than 
1.5 mm Hg at all timepoints. Additionally, the upper limits of the 95% CI should be lower 
than 1.0 mm Hg for the majority of time points measured (ie, 5 of 9).

appropriate statistical techniques and summarized descriptively. Full details will be provided in the 
Statistical Analysis Plan. 
Sample Size Justification:  
The sample size is not based on a formal sample size calculation; this study is planned to provide 
sufficient data to power the Phase 3 study.

NOTE: Subjects using ocular hypotensive medications must have undergone the appropriate required washout period prior to Visit 3/Qualification/Baseline. 
NOTE: If a study subject is discontinued from study medication before Visit 6/Day 84 but after Visit 3/Qualification/Baseline/Day 1, every effort should be 
taken to perform all the procedures listed for Visit 6/Last Day of Treatment (Section 10.4.3). If the subject is willing to remain at the site for the 8-hour visit, it 
should be conducted as specified, but if the subject is not willing to remain for the full duration, the VF test and the dilated ophthalmoscopy should be conducted 
as the last ophthalmic assessments in the early discontinuation visit. 
a Mid-washout safety check for subjects undergoing 28-day washout periods (i.e., prior prostaglandin analogs, rho-associated protein kinase [ROCK] inhibitors, 
or β-blockers) may be performed at the Investigator’s discretion. 
b The window for each time point is ± 30 minutes. For Visit 4/Day 15, Visit 5/Day 42, and Visit 6/Day 84, the 2 h post-dose timepoint will fall around 
10:00 AM, but the timing of the IOP measurement is dependent on the time study medication was administered at the site that day and should be 2 hours 
(± 30 minutes) after the dose was administered. 
c All AEs that occur following consent and until the final study visit (Visit 6/Day 84) should be collected and recorded on the AE eCRF page. 
d Required only for women of childbearing potential. At Visit 3/Qualification/Baseline/Day 1 it must be performed prior to randomization. At Visit 6/Day 84 it 
may be performed anytime. 
e HR and BP will be measured seated after at least 5 minutes rest. Vital signs may be repeated once, after at least an additional 5 minutes rest in the seated 
position, if they are out of range.

f It is preferred that conjunctival hyperemia be graded as part of the external eye exam performed prior to biomicroscopy. 
g At Visit 3/Qualification/Baseline, IOP will be taken bilaterally at 8:00 AM, 10:00 AM, and 4:00 PM (each ± 30 minutes). At Visits 4, 5, and 6, IOP will be 
taken bilaterally at 8:00 AM, 2 hours after study medication dosing at the clinical site (~10:00 AM), and at 4:00 PM (each ± 30 minutes). Two consecutive IOP 
measurements of each eye will be performed. If the 2 measurements differ by more than 2 mm Hg, a third measurement will be taken. Consult the Study 
Manual for specific details. 
h Visual field measurement may be performed within 90 days prior to Screening if a test meeting the protocol requirements was performed and the results were 
documented. If the VF performed at or within 90 days prior to Visit 1 does not meet study required parameters, it may be repeated (test should be prior to 
randomization at Visit 3/Qualification/Baseline).The procedure may be performed at any time during the visit prior to dilation for ophthalmoscopy. 
i Gonioscopy may be performed within 90 days prior to Screening. The procedure must be performed after IOP measurement and before dilation for 
ophthalmoscopy. 
j Pachymetry may be performed within 90 days prior to Screening. The procedure may be performed at any time during the visit after IOP measurement. 
k Plasma concentration will be measured in a subset of 40 subjects; samples will be collected 2 hours (± 30 minutes) after study medication dosing at the clinical 
site. 
l Dose instillation should occur as close as possible to 15 minutes after IOP measurement, but not before 10 minutes after IOP measurement. Artificial tear use is 
prohibited within 10 minutes of instillation of study medication. 
m Subjects will be asked to rate the tolerability of the drop according to the following 4-point scale: 0 = No discomfort, 1 = Mild discomfort, 2 = Moderate 
discomfort, 3 = Severe discomfort. This rating should take place ≥ 10 minutes after the IOP measurement. 
n Study medication accountability may be performed at any time during the visit. 
o Compliance will be monitored via subject-reported missing doses in the Missed Doses Log. Documentation of compliance may be performed at any time 
during the visit.

INTRODUCTION 
BTQ-1901 (nebivolol) and BTQ-1902 (timolol) ophthalmic suspensions are being developed by 
Betaliq, Inc. (the Sponsor) for the treatment of elevated intraocular pressure (IOP) in patients 
with ocular hypertension (OHT) or primary open-angle glaucoma (POAG). Glaucoma is a 
leading cause of blindness worldwide. The global prevalence is estimated to be 64 million people 
in 2013 and it is expected to increase to nearly 112 million in 2040 (Tham et al, 2014).  
Intraocular pressure is balanced between the secretion of aqueous humor by the ciliary body and 
drainage of aqueous humor through 2 independent pathways—the trabecular meshwork and 
uveoscleral outflow pathways. In POAG, the most common form of glaucoma, there is increased 
resistance to aqueous outflow through the trabecular meshwork. The same mechanism applies to 
OHT, in which IOP is elevated without visual field (VF) deficits or clinically apparent damage to 
the optic nerve. Mechanical stress from continued elevated IOP may result in progressive 
damage to the optic nerve, which can result in visual disability leading to blindness.  
Elevated IOP in eyes with POAG is typically treated with topical ophthalmic medications. Many 
patients with OHT are untreated, but topical hypotensive medication has been found effective in 
delaying or preventing the onset of POAG; in the Ocular Hypertension Treatment Study, the 
incidence of OAG after 60 months of follow-up was 9.5% in the observation group vs 4.4% in 
the treated group (Kass et al, 2002). The most frequently used medications are prostaglandin 
analogues, which increase uveoscleral outflow of aqueous humor, and beta(β)-adrenergic 
blockers, which reduce aqueous humor production. While β-blockers are well tolerated locally, 
they may have important systemic adverse events (AEs), such as bronchospasm, decreased heart 
rate, and congestive heart failure, all of which may limit their use. 
The Sponsor is developing two β-blockers, BTQ-1901 and BTQ-1902, in a unique vehicle 
composed of one excipient, the inert and anhydrous semifluorinated alkane, 
perfluorohexyloctane (F6H8). F6H8 is a clear, colorless, chemically inert liquid without 
pharmacologic activity. Both BTQ-1901 and BTQ-1902 are free of other excipients like oils, 
surfactants, buffers, and preservatives, and are administered in a multidose bottle rather than a 
unit dose vial. Due to the low surface tension of F6H8, the resulting eye drops are relatively small, 
with a volume of approximately 11 μL/drop.  
The active ingredient of BTQ-1901 is nebivolol, a β1 selective β-blocker. The chief advantage of 
β1 selectivity is the absence of β2-adrenergic inhibition which minimizes the risk of respiratory 
side effects. Nebivolol also stimulates nitric oxide release via stimulation of the β3 receptor 
which produces a vasodilatory effect (Kuroedov et al, 2004) that may improve blood flow to the 
optic nerve. While extensively used as a systemic blood pressure medication (Bystolic® was 
approved by the United States [US] Food and Drug Administration [FDA] in 2007 [Bystolic 
package insert, 2019]), nebivolol has not been evaluated for ocular use as an ocular hypotensive 
therapy.  
The active ingredient of BTQ-1902 is timolol. Timolol was the first topical ocular β-blocker 
approved by the FDA (1978), and it is still an integral part of the standard of care for glaucoma. 
Utilizing F6H8 as the vehicle for the BTQ-1901 and BTQ-1902 ophthalmic suspensions allows 
development of these products as non-preserved suspensions in a multi-dose bottle, thus 
minimizing tolerability and ocular irritation issues that may arise when eye drops contain 
preservatives or phosphates. This quality may potentially result in fewer ocular AEs.

Importantly, it is postulated that the resulting drug products might have less systemic absorption 
and fewer negative systemic AEs because of the smaller drop size. 
Nonclinical pharmacology, pharmacokinetics, and toxicology studies were conducted in support 
of the development of timolol (topical ocular route) and nebivolol (systemic route). Based on the 
results of the 28-day and 6-month repeat dose toxicology studies in albino rabbits, the 
pharmacological and toxicological data for BTQ-1901-A, BTQ-1901-B, and BTQ-1902 are 
considered adequate to support their safe clinical use for this initial Phase 2 clinical trial. There 
were no significant macroscopic or microscopic findings observed in rabbits dosed with 
nebivolol 1.0% ophthalmic suspension (BTQ-1901-B) 4 times daily for 28 days or twice daily 
(BID) for 6 months, or with timolol 0.5% ophthalmic suspension (BTQ-1902) BID for 6 months. 
Moreover, systemic accumulation of nebivolol 1.0% and timolol 0.5% was very low after the 
6-month treatment period (around the lower limits of quantification [LLOQ]). Therefore, ocular 
instillation of BTQ-1901 or BTQ-1902 twice daily to subjects with a maximum clinical 
concentration of 1.0% nebivolol or 0.5% timolol for up to 12 weeks is considered safe for the 
initial Phase 2 clinical study.  
BTQ-1901 and BTQ-1902 ophthalmic suspensions are topical treatments for POAG or OHT that 
have not been previously evaluated in clinical trials. The planned first in human (FIH) study is a 
randomized, multicenter, observer-masked study to compare the safety and efficacy of 
BTQ-1901-A, BTQ-1901-B, and BTQ-1902 to timolol 0.5% ophthalmic solution in subjects with 
POAG or OHT in both eyes over a 12-week (84-day) treatment period. For additional 
information regarding BTQ-1901 and BTQ-1902 ophthalmic suspensions, please refer to the 
Investigator’s Brochure.

ophthalmic solution. The study will enroll approximately 240 subjects with POAG or OHT who 
will be treated for 84 days (12 weeks). 
Adult subjects will have POAG or OHT in both eyes (presence of POAG in one eye and OHT in 
the fellow eye is acceptable) that requires therapy and elevated IOP adequately controlled, in the 
opinion of the Investigator, on no more than 2 ocular hypotensive medications (fixed dose 
combinations count as 2 medications). Subjects with OHT on no ocular hypotensive medications 
are acceptable. If required, subjects will participate in a minimum washout period of 28 days for 
prostaglandin analogs, rho-associated protein kinase (ROCK) inhibitors, or beta (β) blockers; 
14 days for adrenergic agonists; and 5 days for muscarinic agonists or carbonic anhydrase 
inhibitors (CAIs). A mid-washout onsite safety check may be conducted, at the Investigator’s 
discretion, for subjects undergoing a 28-day washout period.  
Eligible subjects must have unmedicated IOP measurements at Visit 3/Qualification/Baseline 
≥ 22 and ≤ 34 mm Hg at 8:00 AM and ≥ 18 and ≤ 34 mm Hg at 10:00 AM and 4:00 PM (each 
qualifying eye must fall within the required IOP range at all 3 time points and must be at least 
22 mm Hg at each consecutive measurement at the 8:00 AM time point).  
At least one eye must qualify for the study, but even if only one eye meets all inclusion/exclusion 
criteria, both eyes will be treated. If both eyes qualify, the qualifying eye with the higher IOP at 
8:00 AM at Visit 3/Qualification/Baseline will be designated as the study eye. Should the 
8:00 AM IOP be the same in both eyes, then the right eye will be designated as the study eye.  
A total of 240 eligible subjects will be randomized in a 1:1:1:1 ratio into 1 of 4 treatment arms: 
BTQ-1901-A: nebivolol 0.5% ophthalmic suspension; BTQ-1901-B: nebivolol 1.0% ophthalmic 
suspension; BTQ-1902: timolol 0.5% ophthalmic suspension; and timolol 0.5% ophthalmic 
solution and receive 1 drop in each eye BID, morning and evening, for 84 days. 
Randomized study medication will be provided in foil pouches contained in identical-appearing 
boxes to conceal the differences in presentation (5 mL multidose bottles for the BTQ-1901-A, 
BTQ-1901-B, and BTQ-1902 treatment arms versus 10 mL multidose bottles for the timolol 
0.5% treatment arm). The identity of the study medications will be masked to the Investigator 
and study personnel responsible for endpoint-related study procedures. Moreover, Goldmann 
IOP measurements should be performed by the same Investigator/designee throughout the study 
who will be masked to the readout of the tonometer, which will be read and entered into the 
source documentation (whether electronic or paper) by a second staff member once the 
Investigator/designee reaches the correct applanation effect in the slit lamp.  
Study visits will be conducted as follows: Visit 1/Screening/Day -35 to -1, Visit 2/Washout 
Safety Check/Day -14 ± 3 (conducted for subjects undergoing 28-day washout periods at the 
Investigator’s discretion), Visit 3/Qualification/Baseline/Day 1, Visit 4/Day 15 ± 3, 
Visit 5/Day 42 ± 3, and Visit 6/Day 84 ± 3. At Visits 4, 5, and 6, subjects will be evaluated for

Criteria for Withdrawal from the Study/Criteria for Discontinuation 
of Study Medication  
The following are the criteria for considering withdrawal from the study: 
• Withdrawal of subject consent. The subject may request for any reason at any time to 
be withdrawn from the study. 
• Subject lost to follow-up. 
• The Sponsor terminates the study (see Section 6.4). 
If a subject withdraws from the study, the principal reason for withdrawal will be recorded in the 
electronic case report form (eCRF). Subjects who are withdrawn will not be replaced.

30 
 
If a study subject fails to attend a study visit at any point during the study period, every effort 
should be made to keep the subject in the study and conduct all study visits as scheduled; all 
attempts to contact the subject must be documented. If the subject relocates during the study 
period, the clinical research organization (CRO), should be contacted to determine if there is a 
possibility that the subject could continue at another clinical site. 
The following are criteria for considering discontinuation from study medication: 
• Pregnancy: If a subject becomes pregnant during the study, the subject will be 
withdrawn from study medication and followed through the conclusion of the 
pregnancy (Section 9.5.3). 
• Adverse event: A clinically significant or serious AE (SAE) that in the Investigator’s 
or Medical Monitor’s judgment, suggests that continued administration of study 
medication is not in the subject’s best interests for safety reasons. Additionally, if an 
AE requires treatment, the Investigator in consultation with the Medical Monitor may 
determine that study medication should not be concurrently administered with a 
required concomitant medication. 
• Intraocular pressure in either eye >34 mm Hg during the treatment period. 
• Subject request: Subject requests to be withdrawn from study medication. 
When possible, a decision to discontinue a subject from study medication should first be 
discussed with the Medical Monitor. If a subject is discontinued from study medication, every 
effort should be made to encourage the subject to continue to attend study visits to be followed 
for safety, rather than withdrawing the subject from the study or, failing that, to perform all early 
discontinuation assessment procedures at the visit the subject is withdrawn (Section 10.5).  
In case a subject must be withdrawn from the trial, the sponsor will be informed immediately. If 
there is a medical reason for withdrawal, the subject will remain under the supervision of the 
investigator until satisfactory health has returned or the subject´s health has reached a stable 
condition.

TREATMENT OF SUBJECTS 
8.1. 
Description of Study Drugs 
BTQ-1901-A (nebivolol 0.5%), BTQ-1901-B (nebivolol 1.0%), and BTQ-1902 (timolol 0.5%) 
are formulated for topical ocular delivery as sterile, preservative-free ophthalmic suspensions 
and contain the active ingredient (as specified) in a vehicle composed of one excipient, the inert 
and anhydrous semifluorinated alkane, perfluorohexyloctane (F6H8). These study drugs are 
packaged in identical 5 mL multidose bottles to maintain masking of treatment identity.  
The active comparator, timolol, is a sterile, preserved ophthalmic solution that contains timolol 
0.5% and is packaged in 10 mL multidose bottles (Timolol maleate ophthalmic solution 
prescribing information, 2016). 
8.2. 
Randomization and Masking 
Study medication will be randomized in a 1:1:1:1 ratio into 1 of 4 treatment arms (BTQ-1901-A, 
N = 60; BTQ-1901-B, N = 60; BTQ-1902, N = 60; timolol 0.5%, N = 60). A randomized block 
design will be used, and the randomization will be created by a biostatistician independent of the 
trial. Randomization will not be stratified by any factors. 
If subjects meet eligibility criteria (see Section 7) at Visit 1/Screening as well as at 
Visit 3/Qualification/Baseline, sites will access the Interactive Web Response System (IWRS) to 
randomize subjects to study treatment and assign the study medication kit to be dispensed. The 
drug kit and randomization numbers will be recorded in the subject’s eCRF. Study medication 
from the IWRS-assigned kit will be dispensed to the subject after initial dosing at the study site 
on Day 1 (Visit 3/Qualification/Baseline).  
The study will be observer masked. The study medication will be provided in foil pouches 
contained in identical-appearing boxes. The pouches will contain 5 mL bottles for the 
BTQ-1901-A, BTQ-1901-B, or BTQ-1902 treatment arms and 10 mL bottles for the timolol 
0.5% treatment arm (see Section 8.1). An unmasked staff member not involved in performing 
study endpoint-related procedures (i.e., IOP measurement) will be responsible for providing 
dosing instructions, dispensing study medication, and conducting study medication 
accountability and dosing compliance assessment. The identity of the study medications will be 
masked to the Investigator and study personnel responsible for study endpoint-related 
procedures. Moreover, IOP measurements should be performed by the same 
Investigator/designee who will be masked to the readout of the tonometer, which will be read 
and entered into the source documentation (whether electronic or paper) by a second staff 
member once the Investigator/designee reaches the correct applanation effect in the slit lamp. 
8.2.1. 
Unmasking During the Study Period 
Should it be necessary to unmask a subject’s treatment assignment in case of emergency, the 
Investigator may obtain the treatment code for a given randomized subject from the IWRS. The 
treatment code is to be obtained only if a medical emergency exists and knowledge of the 
medication being taken will influence the medical management of the subject.

The following procedure should be followed: 
1. The Investigator should attempt to contact the Medical Monitor via phone before 
unmasking a subject unless it is not possible to do so without risk to the subject. 
2. The Investigator should document the AE and justification for unmasking in the eCRF.  
3. If the subject is to be discontinued from study medication, then ALL procedures 
described in the Early Discontinuation Visit (Section 10.5) should be completed. 
4. The Investigator should contact the CRO at safety@trialrunners.com within 24 hours 
with the subject number and details of the AE or SAE and any action taken. 
8.3. 
Concomitant Medications 
8.3.1. 
Permitted Medications and Treatments 
Therapy considered necessary for the subject’s welfare that will not interfere with the evaluation 
of the study medication may be given at the discretion of the Investigator. If there is any question 
as to whether the medication may interfere, the Investigator should contact the Medical Monitor 
or Sponsor. Whenever possible, medications should be administered in dosages that remain 
constant throughout the study duration. Note: Artificial tear use is permitted prior to and during 
the study period as needed provided the use is not required for severe dry eye disease. Artificial 
tears should not be instilled within 10 minutes of administration of study medication. 
8.4. 
Treatment Compliance 
Treatment compliance will be monitored by subject-reported missed doses assessed at each 
treatment visit (Visit 4/Day 15, Visit 5/Day 42, and Visit 6/Day 84) via response to the Missed 
Doses Log. Subjects will be asked to log if they have missed any doses since the previous visit, 
and if so, the date of missed dose, which dose was missed (AM and/or PM), which eye was not 
dosed (right, left, both), and the reason for the missed dose. These data will be analyzed to 
determine an estimate of compliance over the duration of the study. 
8.4.1. 
Prohibited Medications 
The Medical Monitor should be notified before prohibited medication or therapy is administered 
unless the safety of the subject requires immediate action. The decision to administer a 
prohibited medication or therapy should be done with the safety of the subject as the primary 
consideration. The Medical Monitor MUST be contacted to determine whether the subject 
should continue with study medication. 
Prohibited medications and therapies are summarized in Table 3 and specific details are found in 
the Study Manual. 
8.5. 
Study Medication Materials and Management 
8.5.1. 
Packaging and Labeling 
Study medication will be packaged and labeled at a central packaging facility. Study sites will 
utilize the IWRS to assign kits to subjects. Each kit has 3 boxes (subkits). Contents of the boxes

(subkits) will differ depending upon treatment allocation (either 5 mL multidose bottles or 10 mL 
multidose bottles).   
• Box 1, dispensed at Visit 3/Qualification/Baseline, includes either 1 bottle (5 mL) of 
BTQ-1901-A, BTQ-1901-B, BTQ-1902 OR 1 bottle of timolol 0.5% (10 mL)  
• Box 2, dispensed at Visit 4/Day 15, includes either 2 bottles (5 mL each) of 
BTQ-1901-A, BTQ-1901-B, BTQ-1902 OR 2 bottles of timolol 0.5% (10 mL)  
• Box 3, dispensed at Visit 5/Day 42, includes either 3 bottles (5 mL each) of 
BTQ-1901-A, BTQ-1901-B, BTQ-1902 OR 3 bottles of timolol 0.5% (10 mL)  
8.5.2. 
Storage and Administration 
Study medication must be stored at room temperature, 15°C - 25°C, or 59°F - 77°F, under 
temperature monitored conditions. Subjects should be instructed not to store or place the study 
medication where it can be exposed to extreme temperatures (e.g., refrigeration or leaving it in a 
hot car) or light.  
An unmasked staff member not involved in performing study endpoint-related procedures will 
instruct the subject on proper instillation technique and dispense the first study medication kit at 
Visit 3/Qualification/Baseline. At each study visit during the treatment period (Visit 4/Day 15 , 
Visit 5/Day 42, and Visit 6/Day 84) the subject (or caregiver, if the subject is not able to 
self-administer the medication) will administer the morning dose of study medication at the 
study site, instilling 1 drop in each eye. Before administering the eye drops, the hands should be 
washed. The steps described in detail in the Subject Dosing and Storage Instructions will be 
followed.  
Each day of dosing, the subject will administer one drop to each eye BID (morning and evening).  
8.5.3. 
Study Medication Accountability 
An unmasked staff member not involved in performing endpoint procedures will maintain full 
accountability records for the study medication and will be responsible for recording the receipt, 
dispensing, and return of all supplies of the study medication using the inventories supplied by 
the Sponsor. At each visit subsequent to Visit 3/Qualification/Baseline (i.e., Visit 4/Day 15, 
Visit 5/Day 42, and Visit 6/Day 84) all bottles that were dispensed at the previous visit (empty, 
used, or unused) should be returned to the site in the kit. At Visits 4 and 5, study medication 
accountability procedures will be conducted, and new study medication kits will be dispensed for 
the next study period. At Visit 6 all study medication materials will be returned to the study site, 
and final study medication accountability will be conducted. Visit 6 will be the last day of study 
treatment; no further study medication will be dispensed at this visit. The monitor will review 
dispensing and study medication accountability records at the completion of the study and note 
any discrepancies. All investigational study medication must be stored in a secure facility with 
limited access.

STUDY ASSESSMENTS 
Prior to entry into the study or initiation of any study-related procedures, the subject must read, 
sign, and date the current Institutional Review Board (IRB)-approved version of the informed 
consent form (ICF). A full discussion of informed consent is presented in Section 13.3. 
Ophthalmic procedures should be performed in the order specified in Table 2. 
9.1. 
Demographic and Background Characteristics 
9.1.1. 
Demographic/Medical History 
A complete medical history will be obtained from each subject. Demographic information 
including date of birth, gender, race, ethnicity, iris color, and date of informed consent will be 
recorded. 
9.1.2. 
Concomitant Medications History 
All concomitant medications (prescription and over-the-counter [OTC]) taken at 
Visit 1/Screening and for 90 days prior to Visit 1 and throughout the course of the study will be 
recorded in the Concomitant Medications page of the eCRF. Information regarding the dates of 
first and last dose, site of dosing (e.g., right eye, left eye, both eyes [OU], systemic), and the 
reason the concomitant medication is being taken must be recorded in the eCRF. When a 
concomitant medication has been taken at a stable dose for longer than 6 months, an estimation 
of the year of the start date is adequate. Standard procedural medications will not be captured in 
the eCRF but are recorded on a standard procedural medication log provided by the CRO. 
9.1.3. 
Ophthalmic History and Ophthalmic Intervention History 
Clinically significant ophthalmic history and ophthalmic intervention history will be documented 
and will include any clinically significant previously diagnosed ophthalmic abnormalities and 
ocular surgeries, including laser procedures. 
9.1.4. 
Urine Pregnancy Test 
A urine pregnancy test will be performed for females of childbearing potential at 
Visit 1/Screening, Visit 3/Qualification/Baseline, and Visit 6 or Early Discontinuation Visit. 
9.2. 
Efficacy Assessment 
The efficacy of BTQ-1901-A (nebivolol 0.5%), BTQ-1901-B (nebivolol 1.0%) or BTQ-1902 
(timolol 0.5%) ophthalmic suspensions will be compared to the active comparator (timolol 0.5% 
ophthalmic solution) as measured by mean IOP values in the study eye at each time point at each 
of the Visit 4/Day 15, Visit 5/Day 42, and Visit 6/Day 84 visits (ie, a total of 9 between-group 
comparisons).  
9.2.1. 
Intraocular Pressure 
Intraocular pressure will be measured utilizing a calibrated Goldmann tonometer and using the 
standard of care. NOTE: For  3 through 6, IOP measurements must be made within 30 minutes 
of the protocol-specified time points (8:00 AM, 10:00 AM, and 4:00 PM for Visit 3 and 8:00

AM, 2 hours after study medication dosing at the clinical site [~10:00 AM], and 4:00 PM for 
Visits 4, 5, and 6). For any given subject, IOP should be measured with a calibrated tonometer 
and by the same Investigator/designee, if possible, throughout the study who will be masked to 
the readout of the tonometer, which will be read and entered into the source documentation 
(whether electronic or paper) by a second staff member once the Investigator/designee reaches 
the correct applanation effect in the slit lamp. Two consecutive IOP measurements of each eye 
will be performed. If the 2 measurements differ by more than 2 mm Hg, a third measurement 
will be taken. Consult the Study Manual for specific details. 
9.3. 
Pharmacokinetic Assessments 
Plasma concentration will be measured in a subset of 40 subjects; blood samples will be 
collected 2 hours (± 30 minutes) after study medication dosing at the clinical site at Visit 4/Day 
15 and Visit 6/Day 84. Consult the Study Manual for specific details. 
9.4. 
Safety Assessments 
Safety will be assessed at each visit by LogMAR VA, biomicroscopy, resting heart rate 
(HR)/blood pressure (BP), and AE collection. Ophthalmoscopy/dilated fundus examination and 
VF testing will be performed at Visit 1/Screening and Visit 6/Day 84. Safety/tolerability 
assessments at each visit will include grading of conjunctival hyperemia by the Investigator and 
subjective assessment of comfort/tolerability data by the subject. Ophthalmic assessments should 
be performed in the order in which they appear in the Schedule of Procedures (Table 2).  
9.4.1. 
Visual Acuity 
Best corrected visual acuity measurement will be performed in each eye at all study visits with 
the logMAR eye chart. Consult the Study Manual for specific details. 
9.4.2. 
Biomicroscopy 
A slit-lamp examination will be conducted at each study visit to assess the anterior ocular 
structures. Abnormalities will be documented as abnormal, non-clinically significant (NCS) or 
abnormal, clinically significant (CS). Consult the Study Manual for specific details. 
9.4.3. 
Grading of Conjunctival Hyperemia 
Conjunctival hyperemia will be graded using the McMonnies photographic scale (McMonnies 
and Chapman, 1987a; McMonnies and Chapman, 1987b). Please note that this scale was 
designed for contact lens wearers but validated for non-contact lens wearers (McMonnies and 
Ho, 1991). Consult the Study Manual for specific details. 
9.4.4. 
Vital Signs 
Blood pressure and HR will be measured after at least 5 minutes rest in the sitting position. Vital 
signs may be repeated once, after at least an additional 5 minutes rest in the seated position, if 
they are out of range. Consult the Study Manual for specific details.

9.4.5. 
Ophthalmoscopy/Dilated Fundoscopy 
Ophthalmoscopy/dilated fundoscopy will be conducted, and the structures will be graded as 
normal or abnormal, NCS, or abnormal, CS. Consult the Study Manual for specific details.  
9.4.6. 
Visual Field Testing 
Automated perimetry will be performed at Visit 1/Screening and Visit 6/Day 84. The site should 
perform the automated perimetry assessments following the investigator’s standard practices. If 
the VF performed at or within 90 days prior to Visit 1 does not meet study required parameters, 
it may be repeated (test should be prior to randomization at Visit 3/Qualification/Baseline/ 
Day 1).  
The preferred equipment for the VF is the Humphrey Perimeter using the full threshold 24-2 test 
with the SITA Standard or SITA Fast strategy. The same strategy used for the initial test should 
be used for any subsequent VF test. Visual field results should be reliable. Subjects with a 
functionally significant VF loss, defined as mean deviation greater than -12 dB or a central 
fixation point less than 5 dB in either eye, are excluded from the study. Other equipment may be 
used after approval by the Sponsor. Consult the Study Manual for specific details. 
9.4.7. 
Subjective Grading of Comfort/Tolerability 
Subjective comfort/tolerability data (i.e., rating of drop comfort as assessed by the subject) will 
be collected at each post baseline visit (≥ 10 minutes after the IOP measurement). Consult the 
Study Manual for specific details. 
9.5. 
Adverse and Serious Adverse Events 
9.5.1. 
Definition of Adverse Events 
9.5.1.1. 
Adverse Event (AE) 
An AE is any untoward medical occurrence in a patient or clinical study subject administered a 
study medication (pharmaceutical/biological product) that does not necessarily have a causal 
relationship to this medication. An AE can therefore be any unfavorable and unintended sign 
(including abnormal laboratory findings), symptom, or disease temporally associated with the 
use of the study medication, whether or not related to the study medication. Study medication 
includes the investigational drug under evaluation and the comparator product or vehicle placebo 
that is given during any phase of the study. 
Adverse events are collected from the time the subject signs the ICF through the final study visit. 
Medical conditions/diseases present before starting the investigational treatment are only 
considered AEs if they worsen any time after the subject signs the ICF. Abnormal test results 
constitute AEs only if they induce clinical signs or symptoms or require therapy. 
The occurrence of AEs should be sought by open-ended questioning of the subject at each visit 
during the study. At each clinic visit, study personnel should ask the following question: "Have 
you had any problems since your last visit?” AEs also may be detected when they are 
volunteered by the subject during or between visits or through study assessments.

37 
 
9.5.1.2. 
Serious Adverse Event (SAE) 
An SAE is any untoward medical occurrence that at any dose: 
• Results in death, 
• Is life-threatening, 
Note: The term "life-threatening" refers to an event in which the subject was at risk of 
death at the time of the event; it does not refer to an event which hypothetically might 
have caused death if it were more severe. 
• Results in persistent or significant disability/incapacity (excluding 
progression/outcome of the disease under study), 
• Is a congenital anomaly/birth defect, 
• Requires inpatient hospitalization or prolongation of existing hospitalization, or 
• Is medically significant, i.e., defined as an event that jeopardizes the health of the 
subject or may require medical or surgical intervention to prevent one of the 
outcomes listed above. 
Treatment on an outpatient emergency basis that does not result in hospital admission, or a 
hospitalization that is elective or is a preplanned treatment for a pre-existing condition that is 
unrelated to the indication under study and has not worsened since the start of the study, is not 
considered an SAE. 
All SAEs that are ongoing at the time of completion or discontinuation from the study will be 
followed until stabilization or resolution of the event. 
9.5.2. 
Relationship to Study Drug 
The relationship of AEs to the study medication should be assessed by the Investigator using the 
definitions below. 
Not related: The temporal relationship of the event to the study medication makes a causal 
relationship unlikely, or other drugs, therapeutic interventions or underlying conditions provide a 
sufficient explanation for the observed event. 
Related: The temporal relationship of the event to the study medication makes a causal 
relationship possible or other drugs, therapeutic interventions or underlying conditions do not 
provide a sufficient explanation for the observed event. 
If there is any valid reason, even if undetermined, for suspecting a possible cause-and-effect 
relationship between the study medication and the occurrence of the AE, then the AE should be 
considered “related.” 
If the relationship between the AE/SAE and the investigational product is determined by the 
Sponsor to be “related,” the event will be considered related to the investigational product for the 
purposes of expedited regulatory reporting.

9.5.3. 
Recording Adverse Events 
Adverse events spontaneously reported by the subject and/or in response to an open question 
from the study personnel or revealed by observation, regardless of severity or potential 
association with the study medication or study procedures, will be recorded in the eCRF. 
Changes from baseline assessments that are part of the disease being studied will not necessarily 
be recorded as AEs unless the Investigator deems them as such. Clinically significant changes in 
BP and HR should be reported as AEs. All AEs that occur following consent and until the final 
study visit (Visit 6/Day 84) should be collected and recorded on the AE eCRF page. Serious 
adverse events will be followed until the event is resolved or stabilized. 
The AE term should be reported in standard medical terminology when possible. For each AE, 
the Investigator will evaluate and report the following: 
• Onset (date) 
• Resolution (date) 
• Severity grade (mild, moderate, severe) 
• Relationship to study medication (not related, related) 
• Action taken regarding study medication (none, study medication temporarily 
interrupted, study medication permanently discontinued)  
• Action taken regarding the event (concomitant medication taken; 
hospitalization/prolonged hospitalization; other) 
• Serious (yes/no) 
The severity grade should be determined by the Investigator using the definitions below. 
• Mild: Discomfort noticed but no disruption of normal daily activity  
• Moderate: Discomfort sufficient to cause interference with normal daily activity  
• Severe: Incapacitating, with inability to perform normal activities 
It is important to distinguish between serious and severe AEs. Severity is a measure of intensity 
(as defined directly above) whereas seriousness is defined by the criteria under Section 9.5.1.2. 
An AE of severe intensity may not be considered serious. 
Should a pregnancy occur, it must be reported and recorded on the pregnancy form. Pregnancy is 
not regarded as an AE unless there is a suspicion that an investigational product may have 
interfered with the effectiveness of a contraceptive medication. The subject will be withdrawn 
from study medication and followed through conclusion of pregnancy. The outcome of all 
pregnancies (spontaneous miscarriage, elective termination, normal birth, or congenital 
abnormality) must be followed up and documented. 
9.5.4. 
Reporting Adverse Events 
All SAEs (related and unrelated) will be recorded following consent and until the final study 
visit, Visit 6/Day 84, following the end of treatment exposure. Any SAEs suspected to be related 
to the investigational product should be reported.

Any SAE that occurs must be reported to Trial Runners, the CRO, within 24 hours of its 
occurrence or within 24 hours of learning of its occurrence. Recurrent episodes, complications, 
or progression of the initial SAE must be reported to Trial Runners as follow-up to the original 
episode within 24 hours of the Investigator receiving the information. Information about all 
SAEs will be collected and recorded on the SAE form. All pertinent medical records and 
information collected during the treatment and follow-up of the subject should be maintained at 
the site with a copy emailed to safety@trialrunners.com. The Investigator must assess the SAE 
relationship and complete and sign the SAE form. Trial Runners/the Sponsor may request 
additional information. Follow-up information (e.g., discharge summary) will be retained in the 
subject’s chart and a copy will be emailed to safety@trialrunners.com. 
In addition, all SAEs should be recorded on the Adverse Event eCRF page with the serious 
question marked “Yes”. 
It is the Investigator’s responsibility to notify the approving IRB of any SAEs on a timely basis 
as instructed by the Sponsor following the Sponsor’s determination of causality. 
All subjects who experience an SAE should be followed clinically and undergo the appropriate 
diagnostic evaluations until stabilization or resolution of the event. 
The Sponsor will report all SAEs to the US Food and Drug Administration (FDA) on the 
appropriate schedule depending if the event is drug related or not drug related, expected or 
unexpected (based on the available information in the Investigator’s Brochure). 
Any death occurring during the study and follow up period should be reported as an SAE. For 
any death occurring through the end of the study, regardless of the degree of relationship to study 
medication, the SAE resulting in the death must be reported to Trial Runners. A death occurring 
after completion of the study does not require completion of the SAE form.

STUDY ACTIVITIES 
Table 2 provides a tabular summary of all scheduled visits and procedures to be performed 
during the clinical study. Ophthalmic procedures should be performed in the order in which they 
are shown in the Schedule of Procedures. Please note that per Section 10.1.1, procedures 
performed at Visit 1/Screening may be split and conducted at a separate visit (preferably within 
1 week after Visit 1) to be scheduled before Visit 3/Qualification/Baseline/Day 1. 
10.1. 
Screening Visit  
Screening eligibility assessments are obtained during the Screening Visit conducted on or 
between Day -35 to -1 (Visit 1), which is dependent on the required washout period for prior 
ocular hypotensive medications. 
10.1.1. 
Visit 1/Screening (Day -35 to -1)  
At Visit 1/Screening, (Day -35 to -1), subjects will provide informed consent before any 
study-related procedures are conducted. Subjects will then participate in screening procedures to 
establish eligibility for the study.  
If necessary, Visit 1 may be split and a separate visit (preferably within 1 week after Visit 1) may 
be scheduled to allow all required screening procedures to be performed before 
Visit 3/Qualification/Baseline. For example, if dilated ophthalmoscopy is not performed because 
the subject prefers not to be dilated at this visit, the subject may return on another day. Also, if 
the VF performed at or within 90 days prior to Visit 1 does not meet study required parameters, 
it may be repeated (test should be prior to randomization at Visit 3/Qualification/Baseline). 
At the end of the visit/split visit, inclusion/exclusion criteria will be reviewed. Eligible subjects 
will begin the washout period that is required for the ocular hypotensive medication the subject 
was receiving or, if medication naïve, be scheduled for Visit 3/Qualification/Baseline.

that IOP can be taken at 8:00 AM, at 2 hours after the dosing of study medication at the clinical 
site (~10:00 AM), and at 4:00 PM (each ± 30 minutes).  
Subjects should be reminded before each visit not to dose in the morning before coming to the 
site and to bring their box containing all study medication materials (opened and unopened 
bottles/vials and pouches) to the study site for drug accountability/treatment compliance 
assessment. When the subject arrives, confirm that the previous day’s evening dose of study 
medication was administered, and the morning dose of study medication has not been 
administered. Subjects who did not dose the evening before or who dosed prior to the morning 
visit MUST be rescheduled, even if the next appointment is out of window.

Early Discontinuation Assessment Procedures 
If a study subject is discontinued from study medication before Visit 6/Day 84 but after 
Visit 3/Qualification/Baseline/Day 1, every effort should be taken to perform all the procedures 
listed for Visit 6 (Section 10.4.3).  
If the subject is willing to remain at the site for the 8-hour visit, it should be conducted as 
specified, but if the subject is not willing to remain for the full duration, the VF test and the 
dilated ophthalmoscopy should be conducted as the last ophthalmic assessments in the early 
discontinuation visit.

STATISTICS 
11.1. 
General Considerations 
This is a Phase 2 study to evaluate ocular and systemic safety and the efficacy of BTQ-1901-A, 
BTQ-1901-B, and BTQ-1902 ophthalmic suspensions in comparison to timolol 0.5% ophthalmic 
solution in subjects with POAG or OHT. 
Subjects will be randomized in a 1:1:1:1 ratio into 1 of 4 treatment arms and receive 1 drop in 
each eye BID, morning, and evening, for 84 days: 
• BTQ-1901-A (nebivolol 0.5% ophthalmic suspension) (N = 60) 
• BTQ-1901-B (nebivolol 1.0% ophthalmic suspension) (N = 60) 
• BTQ-1902 (timolol 0.5% ophthalmic suspension) (N = 60) 
• Timolol 0.5% ophthalmic solution (N = 60) 
A biostatistician will perform statistical analyses as agreed with the Sponsor according to the 
Statistical Analysis Plan (SAP).  
Primary efficacy analysis will be conducted on the per protocol (PP) population. Efficacy 
analyses will also be conducted on the intent to treat (ITT) population. Safety analyses will be 
performed using the safety analysis population. Definitions for all of the analysis populations can 
be found in Section 11.3. 
At least one eye must qualify for the study. Even if only one eye meets all inclusion/exclusion 
criteria, both eyes will be treated. If both eyes qualify, the qualifying eye with the higher IOP at 
8:00 AM at Visit 3/Qualification/Baseline will be designated as the study eye. Should the 
8:00 AM IOP be the same in both eyes, then the right eye will be designated as the study eye. 
At each IOP measurement time point, 2 consecutive IOP measurements of each eye will be 
performed. If the 2 measurements differ by more than 2 mm Hg, a third measurement will be 
taken. Mean IOP is calculated as the mean of 2 measurements or as the median of 
3 measurements. 
A detailed SAP will be finalized prior to database lock. The analysis of continuous and ordinal 
variables will use the applicable parametric methods (t-test, analysis of variance [ANOVA], and 
analysis of covariance [ANCOVA], and mixed models for repeated measures [MMRM]). 
Descriptive statistics will be used to summarize continuous outcomes (number of subjects [N], 
mean, standard deviation or standard error of the mean, median, maximum, and minimum) and 
categorical variables (frequency and percentage) at each assessment time point (the time points 
at which data are collected are specified in the Schedule of Procedures—see Table 2). 
The primary efficacy analysis will be the between-group comparison of the mean IOP values in 
the study eye at each time point at each of the Visit 4/Day 15, Visit 5/Day 42, and Visit 6/Day 84 
visits (ie, a total of 9 between-group comparisons). 
Final analyses of efficacy will be conducted when all subjects complete Visit 6.

11.1.1. 
Handling of Missing Data 
All efficacy analyses will be based on observed cases (without imputation). Multiple imputation 
methods and single imputation methods (e.g., last observation carried forward [LOCF]) will be 
utilized for sensitivity analyses for select variables. Full details will be provided in the SAP. 
11.2. 
Determination of Sample Size 
The sample size is not based on a formal sample size calculation; this study is planned to provide 
sufficient data to power the Phase 3 study. 
11.3. 
Analysis Populations 
Three populations will be used for analysis, as described below. 
11.3.1. 
Populations for Efficacy Analysis 
11.3.1.1. Intent-to-Treat (ITT) Population 
The ITT population is defined as all randomized subjects. Supplemental efficacy analyses will be 
conducted on the ITT population. 
11.3.1.2. Per-Protocol (PP) Population 
The PP population consists of those subjects in the ITT population who were randomized and 
dosed and had no major protocol deviations. The primary efficacy analysis will be conducted on 
the PP population. 
11.3.2. 
Safety Population  
The safety population is defined as all randomized subjects who received at least one dose of the 
allocated study medication. All safety analyses will be performed using the safety population. 
11.4. 
Demographics and Baseline Characteristics 
Subject demographic and baseline characteristics will be summarized for all analysis 
populations. Summary tables will be supported with individual subject data listings. 
11.5. 
Efficacy Analysis 
Efficacy analyses will be performed on the PP population for the primary efficacy endpoint using 
observed data only. Analysis of the efficacy endpoints will also be conducted with the ITT 
population. 
Efficacy data will be presented in tables of descriptive statistics and frequency distribution. All 
summary tables will be supported with individual subject data listings. 
The efficacy measures (IOP) taken at Visit 3/Day 1 at 8:00 AM, 10:00 AM, and 4:00 PM will 
serve as baseline.

11.5.1. 
Hypothesis Testing 
The primary efficacy analysis will be the between-group comparison of the mean IOP values in 
the study eye at each time point at each of the Visit 4/Day 15, Visit 5/Day 42, and Visit 6/Day 84 
visits (ie, a total of 9 between-group comparisons). A hierarchical analysis will be conducted to 
compare each of the investigational products against the comparator, timolol 0.5%, as follows: 
(1) BTQ-1902, (2) BTQ-1901B, and (3) BTQ-1901A.  
To demonstrate noninferiority, the upper limits of the 2-sided 95% confidence interval (CI) for 
the difference between each comparison should be lower than 1.5 mm Hg at all timepoints. 
Additionally, the upper limits of the 95% CI should be lower than 1.0 mm Hg for the majority of 
time points measured (ie, 5 of 9).  
All other comparisons are considered exploratory. 
11.5.2. 
Primary Efficacy Endpoints 
The primary efficacy endpoint will be IOP values at each time point (8:00 AM, 2 hours after 
dosing of study medication [~10:00 AM], 4:00 PM) at Visit 4/Day 15, Visit 5/Day 42, and 
Visit 6/Day 84. 
11.5.3. 
Primary Efficacy Analysis 
A summary of the efficacy endpoints will be prepared at each time point.  
The between-treatment comparison will employ an MMRM with treatment, visit/time, 
treatment-by-visit/time interaction, and baseline values as fixed effects. Linear contrasts will be 
used to calculate the confidence intervals at all visit/times.  
Sensitivity analyses include repeating the primary analysis with the ITT population, imputing 
missing data using multiple imputation techniques and repeating the primary analysis; utilizing 
LOCF imputed data and ANCOVA models at each visit/time point; and using Wilcoxon rank 
sum tests to compare treatments at each time point. Full details will be provided in the SAP. 
11.5.4. 
Secondary Efficacy Endpoints 
Secondary endpoints will include the following: 
• Change from baseline (Visit 3/Qualification/Baseline) in the average of the 3 daily 
IOP measurements at each post baseline visit. 
• Time-matched change from baseline (Visit 3/Qualification/Baseline) in IOP 
measurements at all time points at Visit 4/Day 15, Visit 5/Day 42 and Visit 6/Day 84. 
11.5.5. 
Secondary Efficacy Analysis 
Similar analysis methods to those used for the primary efficacy endpoints will be utilized for the 
secondary efficacy endpoints. Full details will be provided in the SAP. 
11.6. 
Safety Analyses 
The safety of BTQ-1901 and BTQ-1902 will be compared to timolol 0.5% with analysis of 
safety variables including bilateral ophthalmic examinations (LogMAR BCVA, slit lamp

QUALITY CONTROL AND QUALITY ASSURANCE 
The Sponsor and/or their contracted agents utilize standard operating procedures (SOPs) 
designed to ensure that research procedures and documentation are consistently 
conducted/prepared to the highest quality standards. These SOPs require compliance with FDA 
regulations and the International Council for Harmonisation (ICH) Good Clinical Practice (GCP) 
guidance. 
The study will be monitored by clinical research associates (CRAs)/monitors provided by Trial 
Runners, the CRO, to verify that the rights and well-being of human subjects are being protected, 
the reported data are accurate, complete, and verifiable, and that the conduct of the study is in 
compliance with the currently approved protocol, with ICH GCP, and with the applicable 
regulatory requirements. 
To ensure compliance with GCP and all applicable regulatory requirements, the Sponsor or its 
agent may conduct a quality assurance audit at any time during or after completion of a study. 
The Investigator will be given adequate notice if he/she is selected for an audit. The audit will 
include but is not limited to a review of all informed consent/assent forms, medical records, and 
regulatory documentation; an assessment of study conduct and protocol compliance; and a 
review of the study materials receipt, storage, and administration. At the conclusion of an audit, 
the auditor will conduct a brief meeting with the Investigator to review the findings of the audit.

ADMINISTRATIVE CONSIDERATIONS 
13.1. 
Institutional Review Board (IRB) Approval 
The IRB must review, approve, and provide continuing review of the clinical study protocol, 
protocol amendments, the informed consent documents, subject recruitment advertisements, and 
any other written information to be provided to the subjects. Initial IRB approval is an 
affirmative decision that the clinical study has been reviewed and may be conducted at the study 
site within the constraints set forth by the IRB, the institution, GCP, and applicable regulatory 
requirements. A copy of the IRB approval letter for the protocol, the informed consent, the 
intended advertising, and any written material to be provided to the subject must be submitted to 
the Sponsor or designee prior to release of investigational supplies to the study site. Progress 
reports and notifications of serious adverse reactions will be provided to the IRB according to 
local regulations and guidelines. The IRB must be notified of completion or termination of the 
study. The study site must maintain an accurate and complete record of all reports, documents, 
and other submissions made to the IRB concerning this protocol. 
13.2. 
Ethical Conduct of the Study 
The study will be conducted according to all stipulations of the protocol, including all statements 
regarding confidentiality, and in compliance with ICH guidelines, and all applicable US federal 
regulations and local legal and regulatory requirements. 
13.3. 
Subject Information and Consent 
A sample ICF containing the required elements of informed consent will be provided by the 
Sponsor or designee. Any changes made to this sample must be approved by Betaliq or designee 
prior to submission to the IRB. After approval by the Sponsor or designee, the ICF must be 
submitted to and approved by the IRB. The informed consent must be written in a language in 
which the subject is fluent. Regulations require that foreign language informed consent forms be 
submitted to the IRB for approval. The foreign language translation is required to contain a 
statement of certification of the translation. The Investigator must forward a copy of the consent 
forms, the certified foreign language translation, and an IRB approval letter to the Sponsor or 
designee. 
It is the responsibility of the Investigator to inform each subject of the purpose of this clinical 
trial, including possible risks and benefits, and to document the informed consent process. Prior 
to undergoing any study-related procedures, the subject must read, sign, and date the current 
IRB-approved version of the informed consent form. The original informed consent form is to be 
retained by the study site, and a copy of the signed consent form is to be given to the subject. 
13.4. 
Subject Confidentiality 
Data generated for the study should be stored in a limited-access file area and be accessible only 
to representatives of the study site, the Sponsor, Trial Runners, the IRB, and FDA/relevant 
regulatory agencies. Medical information resulting from a subject’s participation in this study 
may be given to the subject’s personal physician or to the appropriate medical personnel 
responsible for the subject’s welfare. No information that can be related to a specific individual

subject will be released or used in any fashion without the signed written consent of that subject. 
All reports and communications relating to study subjects will identify subjects only by initials 
and subject identification number. Complete subject identification will be kept by the 
Investigator for purposes of long-term follow-up, if needed. This information will be treated with 
strict adherence to professional standards of confidentiality. 
13.5. 
Study Monitoring 
The study will be monitored by Trial Runners on behalf of the Sponsor in accordance with 
current GCP to assure compliance with the study protocol and the quality of the data collected. 
Monitoring visits will occur as required and could include a study initiation visit, monitoring 
visit(s), and a study close-out visit. Training will be provided for key investigative personnel in 
all aspects of study conduct. The Investigator will be responsible for making sure that site 
personnel are provided adequate training on conducting delegated tasks.  
Before a site can enter a subject into the study, a representative of the Sponsor will: 
• Determine the adequacy of the facilities 
• Discuss with the Investigator(s) and other personnel their responsibilities regarding 
protocol adherence and the responsibilities of the Sponsor and or its representatives 
This study will utilize electronic data capture (eDC) to optimize the eCRF source verification 
process with limited separate source documentation. Monitors will review e-source data and 
overall study data/consistency remotely and query discrepancies based upon eCRF entries (eCRF 
initial entry is the source). During this monitoring, data are reviewed as entered by the site, and 
the monitors will flag any abnormalities, trends, or safety signals for Medical Monitor review 
and monitor follow-up onsite, if necessary. Refer to the Study Manual for details regarding the 
direct data entry of study assessments and requirements for maintaining additional source 
documentation via paper/medical record. 
During visits to the study site, the monitor may review the source documents including but not 
limited to signed informed consent forms, inclusion/exclusion checklist, medical/ocular history, 
concomitant medications, study material accountability and storage, the reporting procedures for 
AEs, SAEs, and protocol deviations. The CRA will review the study documents to ensure all 
documentation is current and only qualified and trained staff are appropriately delegated study 
related tasks. The CRA will also review the site-specific processes and research-related SOPs to 
ensure appropriate Investigator oversight is being maintained and documented as required by 
GCP/ICH. 
All data generated during this study and the medical records/documents from which they 
originated are subject to inspection by the Sponsor or designee, the FDA, and other regulatory 
agencies. The Investigator must notify the Sponsor or designee promptly of any inspections 
scheduled by regulatory authorities. 
Upon completion of the study, the clinical monitor will conduct a final visit (closeout) to the site. 
The objectives of this visit are to ascertain that all regulatory records and reports are complete, 
verify that the investigational product (IP) and other supplies have been accounted for 
(returned/destroyed), and ensure that the Investigators are aware of their responsibilities once the 
study ends.

The Investigator is responsible for permitting the Sponsor or designee direct access to any study 
documents for monitoring and auditing purposes, for providing adequate space for monitoring, 
and for addressing any questions or issues that might be raised by the monitor or auditor on a 
timely basis. 
13.6. 
Case Report Forms and Study Records 
Data relating to study procedures may be entered by site personnel directly onto eCRFs available 
in the study’s eDC system. When the eCRF is the first place study data are recorded, it will be 
the source document; exceptions are detailed in the Study Manual. Paper source documents will 
be retained at the study site when appropriate. 
13.7. 
Protocol Deviations 
The Investigator should not deviate from the requirements of this protocol except in the event of 
a medical emergency.  
A major protocol deviation is defined as nonadherence to the protocol that involves 
inclusion/exclusion criteria, affects subject safety, or has the potential to affect the integrity of 
the data, for example, enrollment of a subject who does not meet key eligibility criteria, or 
failing to collect data necessary to interpret primary endpoints. All protocol deviations will be 
reported to the Sponsor by entering the event in the appropriate eCRF page. Protocol deviations 
should be reported to the IRB in accordance with IRB-specific guidelines. If there is any 
question as to whether the deviation is reportable, the Sponsor or designee and the IRB should be 
contacted. If subjects are enrolled in error they may be removed after review by the Medical 
Monitor, but removal is not required. Major and minor protocol deviations will be defined before 
unmasking. 
All changes to the protocol will be made by the Sponsor or designee as an approved amendment 
to the protocol, submitted to the FDA, and approved by the IRB prior to implementation. 
13.8. 
Access to Source Documentation 
A trial-related monitoring audit, review by the IRB, and/or regulatory inspection may be 
conducted at any time during or after completion of a study (Section 12). The Investigator will 
be given adequate notice if he/she is selected for an audit and must provide direct access to study 
documentation. The audit may include, but is not limited to, a review of all informed consent 
forms; a review of medical records; a review of regulatory documentation; an assessment of 
study conduct and protocol compliance; and a review of the study materials receipt, storage, and 
administration. 
13.9. 
Data Generation and Analysis 
Management of data and the production of the clinical study report will be the responsibility of 
the Sponsor or its designee. 
During the trial, data queries will be generated for data items that are potentially erroneous and 
require appropriate clarification or correction. Such clarifications and corrections will be

discussed with and approved by site personnel and appropriately documented. Prior to database 
lock, data listings will be generated, and anomalous values investigated. 
13.9.1. 
Retention of Data 
Investigators should retain study-related records at the site until informed by the Sponsor. The 
Investigator will not move study documents or discard any records without notifying the 
Sponsor. If the Principal Investigator moves from the current clinical site, the Sponsor should be 
notified of the name of the person who will assume responsibility for maintenance of the records 
at the clinical site or the new address at which the records will be stored. The Investigator will 
notify the Sponsor as soon as possible in the event of accidental loss or destruction of any study 
documentation. If it becomes necessary for the Sponsor or designee, or the FDA or relevant 
regulatory authorities to review any documentation relating to the study, the Investigator must 
permit access to such records. 
13.10. 
Publication and Disclosure Policy 
All information concerning BTQ-1901, BTQ-1902 and the operations of the Sponsor, such as 
patent applications, formulas, manufacturing processes, basic scientific data or formulation 
information not previously published, are considered CONFIDENTIAL and shall remain the sole 
property of the Sponsor. The Investigator agrees to use this information only in accomplishing 
this study and will not use it for other purposes without the written consent of the Sponsor. 
The publication policy is addressed in a separate agreement.
