PROTOCOL SYNOPSIS 
Study Title: Safety and Efficacy of HB-1 for Panic Disorder: A Mulitcenter, Randomized, 
Double-Blind, Placebo-Controlled Trial 
Protocol Number: 
HB-001 
Phase: 2 
HB-1 and Study Rationale: 
New treatments that safely improve whole brain functional connectivity could radically 
transform outcomes for people suffering from Psychiatric Disorders (Tumati S. 2021).  
Anxiety Disorders (ie, Panic Disorder, Social Anxiety Disorder, Generalized Anxiety 
Disorder, Obsessive Compulsive Disorder, and Specific Phobia) are a clinically diverse group 
of disorders that have significant pathophysiological overlap.  Anxiety disorders commonly 
feature disequilibrium in functional connectivity.  Specifically, simultaneous alterations within 
more than one functional brain network, such as default mode, salience and somatomotor 
networks, are common to these disorders (Kim Y., Yoon H. 2018).  Anxiety disorders also 
commonly feature dysregulations in both adrenergic and angiotensin systems (Winter A. 2019, 
Killgore W. 2014, Milani A. 2017).  For example, patients with Panic Disorder and also 
patients with Post-Traumatic Stress Disorder display atypical brain connectivity in regions that 
govern autonomic nervous system regulation (Faravelli C. 1997, Rotella F. 2014, Reiman E. 
1984, Owega A. 2001).  In fact, successful treatment of symptoms for anxiety disorders is 
associated with resolution of multiple atypical patterns of regional cerebral connectivity 
(Zandvakili A. 2020, Lai C. 2013). 
Currently, no FDA-approved treatments for anxiety disorders are designed to improve whole 
brain functional connectivity by targeting the angiotensin and adrenalin systems 
simultaneously.  This is a critical research gap because anxiety disorders are 1) common, 
2) debilitating, 3) co-morbid and 4) difficult to treat (Cerda M. 2010).  Panic Disorder, for 
example, is prevalent in 6% of primary care patients (Katon W. 1986).  Current FDA-approved 
treatments, which target symptomatology using neurotransmitter-specific approaches, are 
limited due to adverse reactions, including abuse potential.  For example, current treatments 
for Panic Disorder include selective serotonin reuptake inhibitors (SSRIs), which have small to 
medium effects, and benzodiazepines, which are not beneficial for long-term use due to 
tolerance, dependence, cognitive disturbance, and exacerbation of co-morbid mood disorders 
(Otto M. 1989, Edwards R. 1980).  Regarding future treatments, the drugs currently being 
tested for Panic Disorder target mechanisms of action similar to currently approved treatments. 
This study introduces HB-1, a fixed dose combination of 96 mg telmisartan and 288 mg 
verapamil, two previously FDA-approved antihypertensives, as a novel therapeutic agent 
targeting symptoms and quality of life (QoL) for patients with Panic Disorder. HB-1 works by 
re-equilibrating functional networks within the telencephalon and the mesencephalon brain 
regions. HB-1 is a promising treatment for Panic Disorder because Panic Disorder is 
characterized by abnormal physiological stress responses associated with disequilibrium in 

Protocol HB-001

Version 4.0 (02 Dec 2021)

more than one functional brain network. 
This study hypothesizes that, in patients with Panic Disorder, HB-1 demonstrates a 
comparable safety profile compared to the safety profiles of the individual agents; and a 
statistically significant reduction in disease severity, compared to placebo. This study will also 
examine the effects of HB-1 in treating the most commonly experienced co-morbidities in 
patients diagnosed with Panic Disorder. 
These hypotheses are based on literature that describes relationships between psychosocial 
stress, emotional intelligence, theories of human motivation, the adrenergic system, functional 
connectivity, angiotensin receptors, and calcium channels (Lea R. 2019, Zheng Z. 2016, Sagar-
Ouriaghli I. 2018, Keller S. 2003).  This work builds upon a prior observational pilot study 
that demonstrated improvement in anxiety and cognitive symptomatology in a diverse group 
of Neurology & Psychiatry patients who received these co-administered medications in a 
community-based Neuropsychiatry specialty practice.  Regarding safety, adverse events were 
minimal, and systolic and diastolic blood pressure did not change significantly before and after 
an average of nine months of treatment observations.  Regarding effectiveness, drastic 
reductions in symptomatology were noted across a broad array of disabling symptoms in 
patients not only with Panic Disorder but also with common co-morbidities.

Sample Size Justification 
A sample size of 80 patients is planned for the study to be randomized in a 1:1 ratio of active 
to control.   
Assuming a standard deviation of 4.5 in the PDSS, 80 patients will provide for in excess of 
95% power to detect a difference in the mean change (from baseline) in the PDSS score of 
3.75 at an alpha-level of 0.05. This corresponds to a 50% reduction in mean PDSS scores on 
HB-1 and a 25% reduction in mean PDSS scores on placebo, assuming baseline mean PDSS 
scores of 15 for both groups.. 
In addition, with respect to adverse events, the study has approximately 95% power to detect at 

Protocol HB-001 
Honeybrains Biotech 
Version 4.0 (02 Dec 2021)

Page 11 of 60 
least one patient with an event that occurs in 7.2% of patients in either treatment group. 
Statistical Methodology 
The study data will be reported using tabular and graphical displays.  Baseline information and 
safety results will be presented for the safety population consisting of patients who received at 
least one dose of study treatment (active or placebo) during the trial.  Effectiveness 
assessments will be compared on an intent-to-treat basis using the randomized treatment 
assignment.  Demographics and baseline information will be summarized descriptively.  Study 
treatment accountability and exposure will be summarized descriptively.  Study drug exposure 
information will include information of compliance such as the percentage of planned 
treatment used. 
Safety Analyses: 
Descriptive summaries of treatment adverse events, laboratory results, and orthostatic vital 
signs will be provided. C-SSRS (Oquendo MA 2003) results will be provided in a listing. 
Efficacy Analyses: Efficacy will be evaluated by comparing change from baseline of HB-1 
patients versus placebo patients in gold standard outcome measures for panic disorder and its 
common co-morbidities.  For efficacy, the primary endpoint will be change from baseline in 
the PDSS. 
Descriptive summaries and inferential tests are identified in the analysis section.  Significance 
testing will be at the two-sided 0.05 alpha-level and confidence intervals will be at 95% 
confidence.

BACKGROUND 
New treatments that safely improve whole brain functional connectivity could radically 
transform outcomes for people suffering from Psychiatric Disorders (Tumati S. 2021).  Anxiety 
disorders (ie, Panic Disorder, Social Anxiety Disorder, Generalized Anxiety Disorder, Obsessive 
Compulsive Disorder, Post-traumatic Stress Disorder and Specific Phobia) are a clinically 
diverse group of disorders that have significant pathophysiological overlap.  Anxiety disorders 
commonly feature disequilibrium in functional connectivity.  Specifically, simultaneous 
alterations within more than one functional brain network, such as default mode, salience and 
somatomotor networks, are common to these disorders (Kim Y, Yoon H. 2018).  Anxiety 
disorders also commonly feature dysregulations in both adrenergic and angiotensin systems 
(Winter A. 2019, Killgore W. 2014, Milani A. 2017).  For example, patients with Panic Disorder 
and also patients with Post-Traumatic Stress Disorder display atypical brain connectivity in 
regions that govern autonomic nervous system regulation (Faravelli C. 1997, Rotella F. 2014, 
Reiman E. 1984, Owega A. 2001).  In fact, successful treatment of symptoms for anxiety 
disorders is associated with resolution of multiple atypical patterns of regional cerebral 
connectivity (Zandvakili A. 2020, Lai C. 2013). 
This study introduces HB-1, a fixed dose combination of 96 mg telmisartan and 288 mg 
verapamil, two previously FDA-approved antihypertensives, as a novel therapeutic agent 
targeting symptoms and quality of life (QoL) for patients with Panic Disorder. HB-1 works by 
re-equilibrating functional networks within the telencephalon and the mesencephalon brain 
regions.  HB-1 is a promising treatment for Panic Disorder because Panic Disorder is 
characterized by abnormal physiological stress responses associated with disequilibrium in more 
than one functional brain network. 
This study hypothesizes that, in patients with Panic Disorder, HB-1 demonstrates a comparable 
safety profile compared to the safety profiles of the individual agents; and a statistically 
significant reduction in disease severity, compared to placebo. This study will also examine the 
effects of HB-1 in treating the most commonly experienced co-morbidities in patients diagnosed 
with Panic Disorder. 
These hypotheses are based on real-world clinical observation of significant improvement in 
anxiety and cognitive symptomatology in a diverse group of Neurology & Psychiatry patients 
who received these co-administered medications at a community-based Neuropsychiatry 
specialty practice.  Regarding safety, adverse events were minimal, and systolic and diastolic 
blood pressure did not change significantly before and after an average of nine months of 
treatment observations.  Regarding effectiveness, drastic reductions in symptomatology were 
noted across a broad array of disabling symptoms in patients not only with Panic Disorder but 
also with common co-morbidities.  This hypothesis is also based on an extensive body of 
literature that describes relationships between psychosocial stress, emotional intelligence, 
theories of human motivation, quality of life, the adrenergic system, functional connectivity, 
angiotensin receptors and calcium channels (Lea R. 2019, Zheng Z. 2016, Sagar-Ouriaghli I. 
2018, Keller S. 2003) (see Figure 1).

1.1.
Unmet Need
Currently, no FDA-approved treatments for anxiety disorders are designed to improve whole 
brain functional connectivity by targeting the angiotensin and adrenalin systems simultaneously.
This is a critical research gap because anxiety disorders are 1) common, 2) debilitating, 
3) co--morbid and 4) difficult to treat (Cerda M. 2010).  Panic Disorder, for example, is prevalent 
in 6% of primary care patients (Katon W. 1986).  Current FDA-approved treatments, which
target symptomatology using neurotransmitter-specific approaches, are limited due to adverse 
reactions, including abuse potential.  For example, current treatments for Panic Disorder include 
selective serotonin reuptake inhibitors (SSRIs), which have a small to medium effects, and 
benzodiazepines, which are not beneficial for long-term use due to tolerance, dependence, 
cognitive disturbance, and exacerbation of co-morbid mood disorders (Otto M. 1989, Edwards R. 
1980).  Regarding future treatments, the drugs currently being tested for Panic Disorder target 
mechanisms of action similar to currently approved treatments.
Whereas many of the anxiety disorders feature hundreds of novel treatment options in 
development, Panic Disorder represents an important disorder with fewer options in

development.  There are few planned or active Phase 2 or 3 studies for the treatment of Panic 
Disorder in adults. 
1.2. 
HB-1 for the Treatment of Panic Disorder  
The Sponsor plans to develop a single dosage formulation therapy of verapamil and telmisartan 
for the treatment of Panic Disorder in adults.  HB-1 contains telmisartan and verapamil, two 
products previously approved by the FDA for the treatment of cardiovascular conditions.  
Telmisartan (Micardis®) was approved by the FDA in 1998 and Verapamil (Verelan® PM) was 
approved in the United States in 1981.  HB-1 is dosed using a specific ratio of verapamil to 
telmisartan which leads to its unique clinical effects.  HB-1 treatment is expected to help patients 
achieve greater reductions in specific symptomatology, faster psychosocial advancement, and 
higher quality of life, with a mechanism of action related to normalization of asymmetric 
cerebral blood flow patterns that cause disability. 
At this time, Honeybrains has conducted an IRB-approved, observational cohort study of a 
diverse group of neurology and psychiatry patients who received combination therapy with 
telmisartan and verapamil from 2019 to March 2020.  The trial included a total of 102 patients, 
ages 18 to 70, with clinically diagnosed panic disorder, social anxiety disorder, ADHD, and other 
co-morbidities such as PTSD, migraine, and/or chronic musculoskeletal pain.  Overall, the 
treatment appeared to significantly reduce symptomatology without causing adverse 
symptomatology or changes to vital signs.  Specifically, the average self-reported symptom 
severity was significantly reduced in eight of the 10 cardinal neuropsychiatric symptoms 
(ie, anxiety, depression, irritability, apathy, body pain, insomnia, headache, cognitive difficulty) 
post treatment compared to baseline.  Effect sizes were largest for anxiety, apathy, cognitive 
difficulty and overall neuropsychiatric disability.  Psychosocial outcomes (NIH Toolbox General 
Life Satisfaction) were significantly better after combination treatment.  Post-treatment systolic 
and diastolic blood pressure measurements did not change significantly from baseline.  The 
effect of combination therapy on vital signs was no different than the effect of individual 
telmisartan or individual verapamil.  The Overall Medical Review of Symptoms score was not 
significantly higher at one month or last observation; in fact, it was lower.  Also, the rate of 
adverse symptoms from combination treatment was similar to known rates of adverse symptoms 
from verapamil and telmisartan.  Importantly, the lateralization of the Weber test, which 
indicates the dominant side of activity of the auditory functional network, changed significantly 
when patients went on or off treatment, suggesting that the mechanisms of action is acting on 
reversible patterns of functional connectivity. 
In summary, this study suggested that in terms of safety HB-1 was well tolerated, with an 
adverse event profile that is no different than those of the individual agents, and as a novel 
therapeutic agent HB-1 is hypothesized to significantly reduce disease severity in patients with 
panic disorder and ADHD.  An extensive body of literature supports the use of this co-
administration and describes relationships between psychosocial stress, the adrenergic system, 
functional connectivity, cerebral blood flow, angiotensin receptors and calcium channels 
(Kikuchi K. 2020, Jennings JR. 2009).  Collectively, findings from the clinical data and from 
prior research suggest that treatments that normalize cerebral blood flow may lead to more 
complete relief of inter-related neuropsychiatric symptoms (anxiety, depression, irritability, body

pain, fatigue, headache, apathy, cognitive difficulty, psychosis, insomnia) that are germane to 
different neurological and behavioral health disorders.  
1.3. 
HB-1 
HB-1, a fixed dose combination of 96 mg telmisartan and 288 mg verapamil, two previously 
FDA-approved antihypertensives, is a novel therapeutic agent targeting symptoms and QoL for 
patients with Panic Disorder. HB-1 treatment is expected to help patients achieve greater 
reductions in specific symptomatology, faster psychosocial advancement, and higher QoL, with a 
mechanism of action related to normalization of asymmetric cerebral blood flow patterns that 
cause disability. HB-1 is a new treatment which modulates the brain renin angiotensin system 
(RAS) and adrenergic system simultaneously, resulting in a central hemodynamic that improves 
outcomes in different neuropsychiatric disorders. The use of treatments that target central 
mechanisms common to more than one co-morbidity could radically improve the quality of 
outcomes in neurological and behavioral disorders.  
1.4. 
Telmisartan 
Telmisartan, an angiotensin II type 1 receptor (AT1) blocker, is approved for the treatment of 
hypertension.  The pro-inflammatory properties of angiotensin II as well as its anti-inflammatory 
effects are well-established (Fan X. 2017).  Poor adaptation to stress, alterations in 
cerebrovascular function and excessive brain inflammation play critical roles in the 
pathophysiology of many psychiatric and neurological disorders (Saavedra JM. 2012).  AT1 
blockade may have a therapeutic effect in these types of disorders. 
1.5. 
Verapamil Hydrochloride 
Verapamil is a calcium channel antagonist used in cardiovascular diseases such as hypertension, 
angina, and certain arrythmias.  It is used clinically as a racemic mixture that contains equal 
amounts of (R) verapamil and (S) verapamil.  Its antihypertensive effects result from causing a 
decrease in peripheral vascular resistance.  It specifically blocks the L-type calcium channel 
along with other, lesser characterized, calcium channels (T-, P-, and possibly N- and Q-type Ca 
(2+) channels) (Tfelt-Hansen P. 2009, Dobrev D. 1999). 
P-glycoprotein function, which is involved in verapamil BBB efflux, is associated with several 
neurodegenerative and psychiatric diseases (van Assema DM. 2012).  Measures of psychiatric 
morbidity in patients taking verapamil tended to improve, such as measurements of cognitive 
scores and psychiatric comorbidity scores (Palmer A. 1990).  Multiple studies found verapamil 
to be well tolerated in patients with bipolar disorder with therapeutic effects in mania comparable 
to amitriptyline, prazosin and propranolol (Cipriani A. 2016).  Other psychiatric clinical 
measures have shown significant improvement with verapamil therapy such as the Brief 
Psychiatric Rating Scale (BPRS) and general impression.

STUDY DESIGN AND DESCRIPTION 
4.1. 
Study Design 
This is a multicenter, randomized, double-blind, placebo-controlled trial.  All patients with Panic 
Disorder, with or without specified co-morbidities, who meet all of the inclusion and none of the 
exclusion criteria will be eligible.  Patients and researchers will be blinded to their treatment 
group. 
Approximately 80 patients with Panic Disorder will be enrolled and randomized in a 1:1 ratio to 
HB-1 or placebo using a central randomization. 
The study design is presented in Figure 2.  A schedule of assessments is presented in Table 1.

4.2. 
Justification for Study Design, Dose, and Endpoints 
This study was designed as a pragmatic trial because in real-world conditions most panic 
disorder patients have multiple neuropsychiatric co-morbidities and are usually taking one or 
more medications.  Pragmatic trial design was chosen because pragmatic trials are useful to

address questions related to generalizability and variability in response.  Pragmatic trials can be 
useful to evaluate the effectiveness of an intervention in real-world setting, ie, in patients who 
may not be adherent to treatment and/or who have co-morbid conditions.  Pragmatic trials focus 
on a wide range of outcomes, such as symptoms, mechanisms, functional status, quality of life, 
and costs. 
A pragmatic study design that enables wider inclusion of patients, regardless of whether they 
have co-morbidities, or are already on treatment, was also important in order to increase the 
recruitability of patients (reduce exclusionary criteria).  A pragmatic design is enabled by the fact 
that the drug does not interact with most common psychiatric treatments. 
4.3. 
Dosing Frequency 
HB-1 and placebo are dosed once a day (QD), nightly at bedtime (QHS) with or without food. 
4.4. 
Monitoring of Adverse Events 
Safety will be assessed through the monitoring of Adverse Events (AEs), Treatment Emergent 
Adverse Events (TEAEs), clinical laboratory assessments, ECGs, Columbia Suicide Severity 
Rating Scale (C-SSRS) (Oquendo MA 2003), and orthostatic vital signs.  Patients will be 
monitored for safety from the first dose of HB-1 or placebo at study Week 0 through the Safety 
Follow-up visit. Serious adverse events (SAEs) will be reported immedidately to the sponsor and 
recorded in the eCRF. 
Table 2 below provides guidance on the management of known toxicities that have been 
associated with verapamil or telmisartan monotherapy. If any of the following criteria are met, 
the subject will have study treatment discontinued and the Medical Monitor must be informed 
immediately. Subjects may discontinue study treatment, however, and remain in the study (see 
Section 4.5). The stopping criteria listed below will also be captured as adverse events (see 
Section 8).

6.1.7. 
Orthostatic Vital Signs 
Orthostatic vital signs check will be performed at the time points specified in the Schedule of 
Assessments (Table 1).  Orthostatic vital signs should include the following steps based up the 
Agency for Healthcare Research and Quality procedure (Tool3F): 
1. Instruct the patient on the process of orthostatic blood pressure measurement and its 
rationale. 
2. Assess by verbal report and observation the patient's ability to stand. 
3. Have patient lie in bed with the head flat for a minimum of 3 minutes. 
4. Measure the blood pressure and the pulse while the patient is supine. 
5. Instruct patient to sit for 1 minute. 
a. Ask patient about dizziness, weakness, or visual changes associated with position 
change. Note diaphoresis or pallor. 
b. Check sitting blood pressure and pulse. 
c. If the patient has symptoms associated with position change or sitting blood 
 90/60, put patient back to bed. 
6. Instruct patient to stand. 
a. Ask patient about dizziness, weakness, or visual changes associated with position 
change. Note diaphoresis or pallor. 
b. If patient is unable to stand, sit patient upright with legs dangling over the edge of 
the bed. 
c. The patient should be permitted to resume a supine position immediately if 
syncope or near syncope develops. 
7. Measure the blood pressure and pulse 3 minutes after patient stands. Support the forearm 
at heart level when taking the blood pressures to prevent inaccurate measurement. 
8. Assist patient back to bed in a position of comfort. 
9. Document vital signs and other pertinent observations on the nursing flowsheet or in the 
medical record. Note all measurements taken and the position of the patient during each 
reading. 
Subtract values 3 minutes after standing (or if patient cannot stand, then sitting) from lying 
values.  
minutes of standing indicates orthostatic hypotension. Clinically significant orthostatic 
hypotension should be treated per standard of care and the Medical Monitor should be contacted.

Adverse Events (AEs) 
All AEs should be captured on the eCRF from Visit 2/Week 0 through the Safety Follow-up 
visit.  Adverse events considered at least possibly related to study treatment should be followed 
until resolution, return to baseline, or deemed chronic or stable.   
All serious adverse events (SAEs) will be immediately reported to the Sponsor from the time of 
Visit 2/Week 0 (dosing) through the Safety Follow-up/End of Study Visit.  
See Section 8.2 for a full description of the collection and reporting of AEs during this study. 
6.1.11. 
Electrocardiogram (ECG) 
At Visit 1/Screening, Visit 4/Week 4, Visit 5/Week 8 and Visit 6/Week 12 a standard 12-lead 
ECG will be conducted. following an approximate 10-minute rest period in all patients and will 
be interpreted by the Investigator to assess clinical significance. 
6.1.12. 
Weber Test 
A Weber Test will be conducted at Baseline/Visit 2 and Visit 6/Week 12.  The Weber test is a 
test of lateralization of auditory function.  Tap the tuning fork strongly on your palm and then 
 ask the patient 
where they hear the sound.  Normally, the sound is heard in the center of the head or equally in 
both ears.  If there is a conductive hearing loss present, the vibration will be louder on the side 
with the conductive hearing loss.  If the patient does not hear the vibration at all, attempt again, 
 
Weber Test results will be documented on the eCRF.

The Columbia Suicide Severity Rating Scale (C-SSRS) (Oquendo MA 2003) is a suicidal 
ideation rating scale. The scale identifies behaviors and thoughts that are associated with an 
increased risk of suicidal actions in the future. The C-SSRS Baseline/Screening version will be 
conducted at Screening. The C-SSRS Since Last Visit version will be conducted at each post-
Screening visit, including Baseline. 
If the investigator determines that a patient is at risk of suicide or self-harm, appropriate 
ain mental health evaluation must be 
implemented. Patients who meet criteria will be referred to a local psychiatrist for prompt 
evaluation and also to the National Suicide Prevention Hotline. The patient must immediately be 
discontinued from the study. The event should be recorded as either an AE or SAE as determined 
by the investigator and reported within 24 hours to the Sponsor. 
6.1.13.7. Clinical Global Impression-Severity Scale (CGI-S)

6.2.2. 
Contraception and Pregnancy 
The effects of HB-1 on conception, pregnancy, and lactation are unknown. 
Note: According to the information available in the Micardis® (telmisartan) label, telmisartan 
belongs to pregnancy categories C (first trimester) and D (second and third trimesters). When 
pregnancy is detected, discontinue telmisartan as soon as possible, as it can cause fetal harm 
when administered to a pregnant woman. 
According to the information available in Verelan® PM (verapamil hydrochloride) label, 
verapamil belongs to pregnancy category C, there are no adequate and well-controlled studies 
in pregnant women. Verapamil should be used during pregnancy only if the potential benefit 
justifies the potential risk to the fetus. Verapamil crosses the placental barrier and can be 
detected in umbilical vein blood at delivery. 
At Screening, all female patients who are not surgically sterile or postmenopausal must agree to 
use at least 2 acceptable methods of birth control (defined as the use of an IUD, a barrier method 
with spermicide, condoms, or any form of hormonal contraceptives,) for the duration of the study 
and for 4 months after the last dose of study treatment. 
At Screening, all male patients who are not sterile (biologically or surgically) must commit to the 
use of a reliable method of birth control (condoms with spermicide) for the duration of the study 
and for 4 months after the last dose of study treatment.  Male patients should not donate sperm 
for 4 months following the last dose of study treatment. 
Individuals who are involved exclusively in same-sex relationships are exempt from the birth 
control requirements but must agree to abide by the recommendations if they do engage in a 
heterosexual relationship. 
Women who are using oral contraceptives will be monitored for adverse events associated with 
overexposure at each study visit. This should include signs and symptoms of myocardial 
infarction, stroke, and venous thromboembolism.

will include a temperature monitoring device that records required storage conditions for the 
bottles at regular intervals for the entire time the shipment is in transit. 
Upon receipt by the site, the designated site personnel will examine the shipment and 
temperature monitoring devices to verify the study treatment bottles were received in acceptable 
condition.  If not received in acceptable condition, the site must notify their Clinical Research 
Associate and the site should quarantine the study drug until a decision has been made by 
Honeybrains regarding its use.  Once inspected, bottles should be stored at USP Controlled 
Room Temperature Conditions, 20oC to 250C in a locked, limited access area.

7.2. 
Drug Accountability 
The Investigator or designee is responsible for taking an inventory of each shipment of drug 
received and comparing it with the accompanying drug order form. All unused drug will be 
retained at the site.  After full drug accountability and reconciliation, the Investigator will 
dispose of any drug at the clinical trial site per site procedures, or if necessary, all drug will be 
returned to the Sponsor or its designee. Disposition of all drug should be documented, including 
any drug that is lost or damaged. 
7.3. 
Assignment to Treatment 
Once enrolled, each patient will be assigned a unique subject identification number.  This 
ghout 
the study.  Once a subject number is assigned, it cannot be reassigned to any other patient.  All 
patients will either be assigned to receive HB-1 or placebo using a central randomization 
system..  Patients and Investigators will be blinded to the study treatment assignment.  
Study treatment will be dispensed to patients in blinded bottles.  Bottle 1 will be dispensed at 
Visit 2/Week 0; patient will bring it back for accountability at Visit 3/Week 2 and will take it 
back home; patient will return Bottle 1 at Visit 4/Week 4 and will be dispensed Bottle 2 (with 
return of Bottle 2 at Visit 5/Week 8); then Bottle 3 will be dispensed at Visit 5/Week 8 (and 
returned at Visit 6/Week 12). 
7.4. 
Unblinding Procedure 
The study drug blind shall not be broken by the Investigator unless information concerning the 
study drug is necessary for the medical treatment of the subject.  All study assessments and 
assignment of causality for AEs should be performed, if possible, prior to unblinding.  In the 
event of a medical emergency, if possible, the medical monitor should be contacted before the 
study drug blind is broken to discuss the need for unblinding. 
For unblinding a subject, the study drug blind can be broken via the central randomization 
system. 
The sponsor must be notified as soon as possible if the study drug blind is broken.  The date, 
time, and reason the blind is broken must be recorded in the source documents and the same 
information (except the time) must be recorded on the eCRF. 
If any site personnel are unblinded, study drug must be stopped immediately and the subject 
must be withdrawn from the study. 
No change should be made to any prior assessments or data of any subject after unblinding of 
his/her treatment assignment.

SAFETY DATA COLLECTION, RECORDING, AND 
REPORTING 
The Medical Monitor will perform an ongoing blinded review of safety and tolerability and will 
advise on whether it is safe to continue study treatment.  Safety will be assessed through the 
monitoring of TEAEs, clinical laboratory assessments, ECG, Columbia Suicide Severity Rating 
Scale (C-SSRS) (Oquendo MA 2003), and orthostatic vital signs. 
8.1. 
Adverse Events  
8.1.1. 
Definition of an Adverse Event (AE) 
An AE is defined as any untoward medical occurrence associated with the use of a drug, or with 
study participation, whether or not consider related to study treatment.  
An AE can therefore be any unfavorable and unintended sign (including an abnormal laboratory 
finding, for example), symptom, or disease temporally associated with the use of the medicinal 
product, whether or not considered related to the medicinal product.  
AEs include worsening of a pre-existing medical condition as well as clinically significant 
changes from baseline laboratory values/conditions.  Worsening of the preexisting medical 
condition (eg, diabetes, hypertension) means that it has increased in severity, frequency, and/or 
duration, and/or has an association with a significantly worse outcome.  A pre-existing condition 
that has not worsened during the study is not considered an AE. 
8.1.2. 
Definition of Treatment Emergent Adverse Event (TEAE) 
A treatment-emergent adverse event (TEAE) is defined as any event not present prior to the 
initiation of the drug treatment or any event already present that worsens in either intensity or 
frequency following exposure to the drug treatment. 
8.1.3. 
Definition of Serious Adverse Event (SAE) 
An SAE is any untoward medical occurrence that at any dose: 
 Results in death 
 Is immediately life-threatening 
 Requires inpatient hospitalization or prolongation of existing hospitalization.  
- 
Elective or pre-planned treatment for a pre-existing condition that is unrelated to the 
indication under study and has not worsened since signing the ICF (as documented as 
medical history on the eCRF) is not considered an SAE 
- 
Scheduled therapy for the target disease of the study, including admissions for 
transfusion support or convenience, is not considered an SAE 
 Results in persistent or significant disability/incapacity 
 Results in congenital anomaly/birth defect 
 Is considered an important medical event 

Protocol HB-001

Version 4.0 (02 Dec 2021) 
CONFIDENTIAL  
Page 43 of 60 
- 
If an AE does not meet one of the serious criteria, but the Investigator or Sponsor 
considers an event to be clinically important, the event could be classified as an SAE 
 
8.2. 
Procedures for Recording and Reporting Adverse Events 
8.2.1. 
Recording Adverse Events 
Patients will be instructed to report all AEs and will be asked a general health status question at 
each study visit.  All AEs and SAEs occurring in patients will be recorded in the eCRF from 
Visit 2/Week 0 through the Saftey Follow-up Visit after the last dose of drug.  An AE will be 
followed until it is either resolved, has returned to baseline, or is determined to be a stable or 
chronic condition.  All SAEs will be processed as outlined in Section 8.2.2. 
At each required visit during the trial, all AEs that have occurred since the previous visit must be 
reviewed by the Investigator.  The Investigator must determine if the AE is serious or 
non-serious. 
The Investigator must assign the following AE attributes: 
 AE diagnosis or syndrome(s) if known 
 If not known at time of the report, record the signs and/or symptoms as AEs and 
provide an updated report with diagnosis when obtained 
 Dates of onset and resolution 
 Severity as defined per protocol 
 Assessment of relatedness to drug 
 Action taken with drug as a result of the AE 
In general, an AE that is the primary cause of subsequent events should be identified by the 
primary cause (eg, for dehydration due to diarrhea, the AE would be diarrhea).  However, AEs 
occurring secondary to an initiating event that are separated in time should be recorded as 
independent events (eg, sepsis secondary to pneumonia, both events should be recorded). 
8.2.1.1. 
Relationship to Study Treatment 
The Investigator must assess whether the AE may be related to study drug or study mandated 
procedure, when applicable. The relationship is defined below: 
 
 None: The event is related to an etiology other than the study product administration (the 
alternative etiology must be documented in the study 
medical record). 
 Remote: The event is unlikely to be related to the study product and likely to be related to 
factors other than study product. 
 
 Possible: There is an association between the event and the administration of drug, and 
there is a plausible mechanism for the event to be related to the study product; but there 

Protocol HB-001 
Honeybrains Biotech 
Version 4.0 (02 Dec 2021) 
CONFIDENTIAL  
Page 44 of 60 
may also be alternative etiology, such as characteristics of the 
clinical status or 
underlying disease. 
 Probable: There is an association between the event and the administration of drug, there 
is a plausible mechanism for the event to be related to the study product, and the event 
could not be reasonably explained by known characteristics of the 
clinical status 
or an alternative etiology is not apparent. 
 Definite: There is an association between the event and the administration of drug, there is 
a plausible mechanism for the event to be related to the study product and causes other 
than drug have been ruled out and/or the event re-appeared on re-exposure to drug. 
8.2.1.2. 
Adverse Event Severity 
The Investigator will assess the Grade of the AE using the criteria below:  
 Grade 1: Mild; asymptomatic or mild symptoms; clinical or diagnostic observations only; 
intervention not indicated 
 Grade 2: Moderate; minimal, local or noninvasive intervention indicated; limiting 
age-appropriate instrumental activities of daily living (ADL) 
 Grade 3: Severe or medically significant but not immediately life-threatening; 
hospitalization or prolongation of hospitalization indicated; disabling; limiting self-care 
ADL 
 Grade 4: Life-threatening consequences; urgent intervention indicated 
 Grade 5: Death related to AE 
Note: it is important to distinguish between SAEs and severe AEs. Severity is a measure of 
intensity, whereas seriousness is classified by the criteria based on the regulatory definitions as 
described in Section 8.1.3 above. 
8.2.2. 
Reporting of Serious Adverse Events 
SAEs will be reported to the sponsor immediately and recorded on the appropriate eCRF and 
SAE Report Form within 24 hours of the Investigator
experience does not appear to be related to drug, from the Visit 2/Week 0 through the Safety 
Follow-up visit after the last dose of study drug. 
The initial SAE eCRF must be as complete as possible, including details of the current illness 
and SAE, and an assessment of the relationship between the event and drug.  Additional 
information relating to a previously reported SAE must also be reported within 24 hours of the 
Investigator
 The Investigator may also be asked, by the 
Sponsor or designee, to provide clarifications or additional information. 
8.2.2.1. 
Reporting of Serious Adverse Events to Regulatory Authorities and Institutional 
Review Board 
The Sponsor or designee will determine expectedness of 
 product for each reported 
SAE based on the appropriate reference safety information per local requirements.  The Sponsor 

Protocol HB-001

or designee shall notify regulatory authorities of serious, unexpected, and related AEs or other 
AEs, per local requirements.  
The Sponsor or designee shall notify the Investigator of serious, related, and unexpected AE(s) 
submitted to the regulatory agencies, per local country requirements.  
The Investigator will notify the appropriate IRB of serious, related, and unexpected AE(s), or 
significant risks to patients, per local country requirements.  The Investigator must keep copies 
of all AE information on file, including correspondence with the Sponsor or IRBs.

STATISTICAL METHODS 
9.1. 
General Considerations 
This is a multicenter, randomized, double-blind placebo-controlled trial. All patients will be 
randomized in a 1:1 ratio to receive an oral dose of HB-1 or matching placebo once a day.  Study 
data will be provided in listings and sorted by patient number, study period, and assessment time.  
The study results will be displayed using descriptive summary tables and inferential analyses 
completed as described below.  Summaries will be displayed by treatment group for all tables.  
For measurements that have multiple intermediate visits, results for observed data will be 
summarized for each time point. 
Standard numeric descriptive statistics include number of patients or records observed (N), 
mean, standard deviation (std), median, minimum (min), and maximum (max) values. Standard 
categorical descriptive statistics include the count and percentages of patients with a level of the 
variable summarized.  Hypothesis tests will assess the null hypothesis that there is no difference 
between HB-1 and placebo treatment arms.  Testing will be done at the 0.05 alpha-level.  Any 
confidence intervals provided will be at 95% confidence. 
All summaries, statistical analyses, and individual patient data listings described below will be 
completed using Version 9.4 or later of the SAS Statistical Analysis System (SAS Institute, Inc. 
Cary, NC). 
Additional details regarding estimands, including handling of intercurrent events will be 
provided in a separate statistical analysis plan (SAP) to be finalized prior to completion of the 
study and unblinding. 
Determination of Sample Size 
A sample size of 80 patients is planned for the study to be randomized in a 1:1 ratio of active to 
control.   
Assuming a standard deviation of 4.5 in the PDSS, 80 patients will provide for in excess of 95% 
power to detect a difference in the mean change (from baseline) in the PDSS score of 3.75 at an 
alpha-level of 0.05 at 12 weeks. This corresponds to a 50% reduction in mean PDSS scores on 
HB-1 and a 25% reduction in mean PDSS scores on placebo, assuming baseline mean PDSS 
scores of 15 for both groups. 
In addition, with respect to adverse events, the study has approximately 95% power to detect at 
least one patient with an event that occurs in 7.2% of patients in either treatment group. 
Analysis Populations 
Analyses will be performed comparing treatment groups for each of the following populations: 
All Patients  all patients who sign informed consent and are assigned a unique patient 
identification number. 
Intent-to-Treat (ITT)  all patients who are successfully randomized to either the HB-1 or control 
treatment groups. This will be the primary population used for efficacy analyses. Patients will be 
analyzed according to randomized treatment group. 

Protocol HB-001 
Honeybrains Biotech 
Version 4.0 (02 Dec 2021) 
CONFIDENTIAL  
Page 47 of 60 
Safety Population  patients who are randomized and receive at least one dose of study drug.  
This will be the primary population used to summarize all safety data.  Safety summaries will be 
based on the treatment that patients actually receive. 
Handling of Missing Data 
Data may be missing either because an assessment is not completed or if patients have 
withdrawn consent from further participation in the study. Additional details for handling 
missing data will be dependent on the extent of missing data and will be specified in the SAP. 
Adjustments of Multiplicity 
To control for multiplicity of select analyses, a hierarchical approach will be used to test the 
following endpoints in order, each at the 0.05 alpha-level.  These endpoints are 1) PDSS 
(primary efficacy endpoint), 2) mean number of panic attacks, 3) CGI-S.  Irrespective, of the 
significance of these specific measures, planning for future studies will be based on the totality 
of safety and efficacy data and nominal p-values will be reported for all inferential tests.  
Interim Analyses 
Interim analyses are not planned for this study. 
Patient Disposition 
Patient disposition will be summarized for the All Patients population and summarized by 
treatment group and overall for all patients.  The number and percentage of patients who are 
screened, screen-failed, randomized, and completed the treatment period, follow-up period, or 
discontinued the study (including reasons for discontinuation) will be presented. 
Demographics and Baseline Characteristics 
Demographics information will be summarized using descriptive statistics. For gender, race, and 
ethnicity the summarization of those categorical values will be performed using percentages and 
frequency.  Age, height, weight, and BMI will be summarized using descriptive statistics as total 
number of patient observed (n), mean, median, minimum, and maximum.  Listings and 
summaries of demographics, baseline characteristics, and medical history, will be summarized 
by treatment group for the Safety population. 
Extent of Exposure to Study Medications and Treatment Compliance 
All patients will receive an oral dose of HB-1 or matching placebo once a day for a total of 
12 weeks.  One (1) bottle will be dispensed to the patient at Visits 2, 4 and 5.  Study drug 
accountability will be performed at Visits 3  6 and study drug bottles will be returned at Visits 
4-6. 
Drug exposure and compliance will be summarized by treatment for the safety population. Drug 
exposure (in days) will be calculated as: last dose date - first dose date + 1.  Exposure will be 
summarized as a continuous variable for the treatment period.  Percent compliance will be 
calculated by visit and overall for the treatment period.  Compliance will be summarized as a 
continuous variable.

Prior and Concomitant Therapies
All patients with Panic Disorder, with or without co-morbidities will be eligible, as long as they 
are stable on their current psychiatric medications for at least three months as determined by 
Investigator and are willing to remain on current doses of other psychiatric medications 
throughout the length of the trial.  Concomitant medications will be summarized categorically by 
treatment group for the safety population by visit and overall for the treatment period. 
Efficacy and Exploratory Analyses 
All efficacy and exploratory analyses shall be conducted by treatment group on the ITT 
population.  These endpoints are based on measurement scales collected over the visits of the 
study.  Each of the scales may have domains or subdomains.   
A mixed model repeated measures (MMRM) approach, with fixed effects for treatment, visit, the 
treatment-by-visit interaction, baseline, baseline-by-visit, will be used to analyze continuous 
endpoints.  The outcome is the change from baseline to each on-treatment time point. All 
protocol-scheduled time points will be included in the model. The model will use the 
unstructured or Toeplitz (whichever has a better fit by AICC value) within-subject variance-
covariance matrix. The denominator degrees of freedom will be according to the method of 
Kenward-Roger.  The estimated least square (LS) means and their standard errors as well as the 
estimated treatment effect (differences between treatments at each time point) will be 
summarized by treatment. In addition, the 95% confidence intervals of the LS means and the 
difference between treatments, p-values for treatment comparisons will be provided. For 
endpoints without a baseline measurement, baseline and the visit-by-baseline interaction will be 
omitted from the model. The primary analysis timepoint will be at 12 weeks.  
Efficacy Endpoint Analyses 
Scales of interest Panic Disorder are the: 
 Panic Disorder Symptom Severity Scale (PDSS) (Furukawa TA. 2009) 
 Number of panic attacks 
 Clinical Global Impression-Severity Scale (CGI-S) (Guy W. 1976)

Safety Analyses 
Safety endpoints include TEAEs, clinical laboratory abnormalities, changes in ECG, and 
orthostatic vital signs between treatment groups.  C-SSRS (Oquendo MA 2003) results will be 
provided in a listing.  All summaries of safety and tolerability will be performed on data from the 
safety population using descriptive statistics only unless otherwise specified. 
Adverse Events 
All adverse events will be summarized descriptively by group without comparison between the 
groups.  An overall summary of aderse events should be provided to the show the the number 
and percentage of patients with at least one TEAEs, at least one serious TEAEs, at least one drug 
related event, and at least one serious drug-related event.  The total number of each event type 
will also be summarized along the severity and relatedness distribution of all events. 
Summaries of the number and percentage of patients in the safety population with at least one 
adverse event, classified according to preferred term and/or body system using the current

Good Clinical Practice Statement 
This study is to be performed in accordance with the protocol, the Declaration of Helsinki, the 
International Conference on Harmonisation (ICH) Harmonised Tripartite Guideline for Good 
Clinical Practice (GCP) E6 (R2), and all applicable local laws and regulatory requirements. 
10.2. 
Informed Consent (ICF) 
The Sponsor or designee will provide a sample patient informed consent form (ICF) for 
modification, as appropriate, by the Investigator.  The ICF must include all elements required by 
ICH and GCP and must adhere to the IRB/IEC requirements and the ethical principles that have 
their origin in the Declaration of Helsinki. 
The Investigator or designee will explain the nature of the study, its purpose and associated 
procedures, the expected duration, and the potential risks involved to the patient prior to 
enrollment.  The Investigator or designee will obtain written, informed consent.  The patient will 
have ample time and opportunity to ask questions and will be informed about the right to 
withdraw from the study at any time without any disadvantage and without having to provide a 
reason for this decision.  Following the discussion regarding the study, a patient will be asked if 
they are willing to sign and personally date a statement of informed consent.  Only if the patient 
voluntarily agrees to sign the informed consent statement and has done so, may he/she enter the 
study. A copy of the signed and dated ICF will be provided to the patient.  The original signed 
 
The ICF and any other written information provided to the patients will be revised whenever 
important new information becomes available that may be relevant to the patient
there is an amendment to the protocol which necessitates a change to the content of the patient
informed consent.  The Investigator will inform the patients of changes in a timely manner and 
will ask the patients to confirm continuation of their participation in the study by their signature 
on the revised ICF (if applicable).  Any written ICF and written information must receive the 
approval/favorable opinion of the IRB in advance of use.  Any additional approvals from the 
initial ICF should be forwarded to the Sponsor. 
10.3. 
Patient Confidentiality 
The written ICF will explain that study data will be stored in a database, maintaining 
confidentiality in accordance with national data legislation.  All data processed by the Sponsor or 
its representative(s) will be identified by patient number and study code. 
The written ICF will also explain that for data verification purposes, authorized representatives 
of the Sponsor, a regulatory authority, and an IRB may require direct access to parts of the 
hospital or clinic records relevant to the study that include the patient
 
The Investigator must ensure that the patient
documents submitted to the Sponsor, patients should not be identified by their names, but by 
their assigned patient number and study code.  Documents not for submission to the Sponsor, 
such as signed ICF, should be maintained in strict confidence by the Investigator.

Institutional Review Board Requirements 
The final study protocol, including the final version of the ICF, must be approved or given a 
favorable opinion in writing by an institutional review board (IRB) at each clinical trial site.  The 
Principal Investigator must submit written approval from the IRB to the Sponsor before he or she 
can enroll any patient into the study. 
The Principal Investigator is responsible for informing the IRB of any amendment to the 
protocol.  In addition, the IRB must approve all advertising used to recruit patients for the study.  
The protocol must be re-approved by the IRB annually or as required by the IRB, regulations, 
and guidelines. 
Progress reports and notifications of SAEs will be provided to the IRB according to regulations 
and guidelines. 
10.5. 
Case Report Forms and Source Documentation 
eCRFs will be provided for the recording of all data.  The Principal Investigator or designee will 
record data from all observations, tests, and assessments specified in the protocol on the eCRFs 
provided by the Sponsor. 
As used in this protocol, the term CRF should be understood to refer to either a paper form or an 
electronic data record or both, depending on the data collection method used in this study. 
A CRF is required and should be completed for each included subject.  The completed original 
CRFs are the sole property of Honeybrains and should not be made available in any form to third 
parties without written permission from Honeybrains. 
The Investigator has ultimate responsibility for the collection and reporting of all clinical, safety 
and laboratory data entered on the CRFs and any other data collection forms (source documents) 
and ensuring that they are accurate, authentic / original, attributable, complete, consistent, 
legible, timely (contemporaneous), enduring and available when required.  The CRFs must be 
signed by the investigator or by an authorized staff member to attest that the data contained on 
the CRFs is true.  Any corrections to entries made in the CRFs, and /or source documents must 
be dated, initialed and explained (if necessary) and should not obscure the original entry.  
In most cases, the source documents are the hospital's or the physician's subject chart. In these 
cases, data collected on the CRFs must match the data in those charts.  In some cases, the CRF, 
or part of the CRF, may also serve as source documents.  In these cases, a document should be 
, as well as at Honeybrains and clearly identify those data that 
will be recorded in the CRF, and for which the CRF will stand as the source document.
