PROTOCOL SYNOPSIS 
Protocol Title: 
A Randomized, Double-blind, Placebo-controlled Phase II Study of 
BNC210 in Adults with Post-Traumatic Stress Disorder (PTSD). 
Rationale for the Study: 
BNC210 acts through negative allosteric modulation (NAM) of the 
alpha 7 nicotinic acetylcholine receptor and is under development for 
the treatment of anxiety, and trauma and stressor-related disorders. 
 
 
 
 
 
 
 
 
 
 
 
. This study will assess the safety and efficacy of BNC210 in 
subjects with a diagnosis of PTSD, a stress and trauma related 
disorder with limited pharmacotherapy treatment options. 
Objectives: 
Primary Objectives 
• 
To assess the effects of BNC210 on Investigator-rated 
symptoms of PTSD measured by Clinician-Administered 
PTSD Scale for the Diagnostic and Statistical Manual of 
Mental Disorders, 5th Edition (DSM-5) (CAPS-5) scores.  
Secondary Objectives 
• 
To assess the effects of BNC210 on Investigator-rated 
symptoms of PTSD measured by each of the four symptom 
clusters (Intrusion; Avoidance; Negative Alterations in 
Cognition and Mood; Arousal and Reactivity) of the CAPS-5. 
• 
To assess the effects of BNC210 on other psychiatric outcomes 
in subjects with PTSD including anxiety and depression. 
• 
To assess the effects of BNC210 on global functioning and 
Quality of Life in subjects with PTSD. 
• 
To assess the effects of BNC210 on patient-reported outcomes 
in subjects with PTSD. 
• 
To assess the safety and tolerability of BNC210 in subjects with 
PTSD. 
 
 
 
  
 
 
 
 
 
 
 
 
 
 
  
 
 
 
Endpoints 
Primary Efficacy Endpoint 
The effect of BNC210 compared to placebo on baseline to endpoint 
change in CAPS-5 total symptom severity scores after 12 weeks of

Safety Analyses 
Suicidal ideation, self-injurious non-suicidal and suicidal behavior 
will be monitored from Baseline to week 15 using the Columbia 
Suicide Severity Rating Scale (C-SSRS).  
Other 
safety 
parameters 
(e.g. 
vital 
sign 
measurements, 
electrocardiogram (ECG) readings, physical examination, and 
laboratory tests) will be monitored from Baseline to week 15 and 
described using descriptive statistics by treatment group when 
applicable, and by visit otherwise.  
All adverse events (AEs) will be listed and summarized by treatment 
group, organ class and preferred term with:  
• 
The number of subjects with at least one AE and number of 
AEs for each treatment group and overall. 
• 
Analyses taking into account intensity and drug relationship to 
treatment could also be carried out. 
Description of potentially clinically significant values will be 
performed for vital signs, ECG parameters, blood chemistry and 
hematology parameters. All these parameters will be listed by subject 
and measurement time. The data outside of normal ranges will be 
flagged.

Criteria for evaluation: 
Efficacy: Response to treatment will be assessed using the CAPS-5, 
PCL-5, CGI-I/CGI-S, HAM-A, MADRS, CANTAB Cognitive 
Assessment, SDS, PSQI, PGI-I/PGI-S and AQoL-8D. 
Safety: Vital signs, ECG, hematology and blood chemistry, urinalysis, 
physical examinations, C-SSRS and continuous AE reporting. 
Adherence: This will be assessed via blood sampling for 
determination of BNC210 plasma concentrations and counts of 
returned medication bottles. 
  
 
Nicotine intake: The average daily number of tobacco products 
smoked and the use of nicotine replacement products will be recorded. 
Overall Design: 
This is a randomized, double-blind, parallel, placebo-controlled, 
multi-centre study with a 12-week, 4-arm treatment phase (placebo 
and 150mg bid, 300mg bid and 600mg bid BNC210).  Subjects will 
attend a Screening visit within 3 weeks of randomization to confirm 
eligibility.  Approximately 192 subjects who fulfill the inclusion 
criteria and none of the exclusion criteria will be randomized on Day 1 
using a 1:1:1:1 ratio. Subjects will then complete 12 weeks of their 
allocated treatment. The Investigational Product or Placebo will be

taken twice daily (bid) with food.  Subjects will return to the clinical 
site at weekly or 2-weekly intervals to receive study medication, 
complete safety assessments and questionnaires.  Subjects are then 
requested to attend a post-study visit at 15 weeks (i.e., 3 weeks after 
the last treatment). Subjects will undergo assessments for efficacy and 
safety during the study as per the schedule of assessments. 
Study Duration: 
Screening evaluation within 3 weeks of randomization 
Treatment phase: 12 weeks of treatment, bid (weekly or fortnightly 
visits to the clinic). 
Post-study visit:   3 weeks after the last treatment (i.e. 15 weeks after 
the first treatment). 
Recruitment timeframe estimate is 2 years. 
Study Centers: 
Approximately 20-30 centers located in Australia and the United 
States.  
Number of Planned 
Subjects: 
A total of 192 male and female patients with PTSD will be enrolled 
in the study at a 1:1:1:1 ratio (about 48 subjects per treatment arm). 
 
 
 
 
 
 
 
 
 
 
 
Investigational Product: 
BNC210 (150 mg, 300 mg, and 600 mg) administered bid with food 
from a prefilled single-use bottle for 12 weeks (BNC210 will be 
suspended in a vehicle solution).

1 INTRODUCTION AND RATIONALE 
1.1 
Disease Background 
According to the Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition 
(DSM-5), Post-Traumatic Stress Disorder (PTSD) results from exposure to a traumatic event 
during which an individual experienced, witnessed, or was confronted with the actual threat 
of death or serious injury, or the threat to physical integrity to self or others. PTSD symptoms 
can be divided into four clusters: (1) persistent re-experiencing of the trauma, (2) avoidance 
behavior associated with feelings of detachment and emotional numbness, (3) negative 
alterations in cognitions and mood, and (4) symptoms of increased autonomic arousal. 
Treatment is based on early interventions, psychotherapies (cognitive behavioral therapy 
[Otis et al. 2009], exposure, eye movement desensitization and reprocessing [EMDR], etc.) 
and pharmacotherapy. For the latter, only two pharmacological agents, the antidepressants 
Paxil® (paroxetine) and Zoloft® (sertraline), belonging to the selective serotonin reuptake 
inhibitors class (SSRIs), are FDA-approved for the treatment of PTSD, but they have not 
been shown to ameliorate the full range of PTSD symptoms, and complete remission of 
symptoms is rare. Combat exposure, in particular, produces a virulent form of PTSD, which 
is highly resistant to current pharmacological interventions. Overall, antidepressants have (1) 
moderate efficacy (2) marginal efficacy on male military populations (3) rebound effect upon 
treatment discontinuation (worsening symptoms) (4) severe side effects upon initiation of 
treatment (depression, generalized anxiety, panic, substance abuse, suicidal ideation), (5) 
elevated risk of suicide in young adults (non-approved treatment for children) and (6) 
potential for sexual dysfunction. 
Benzodiazepines (BZD) use is not indicated for PTSD. Data on alprazolam show that it has a 
deleterious effect on PTSD recovery during exposure therapy (Rothbaum et al. 2014, Rosen 
et al. 2013) and it is now contraindicated in the Veterans Administration Guideline 
(Kobayashi et al. 2015). The 2008 World Federation of Societies of Biological Psychiatry 
conference have also cautioned against the use of BZDs in PTSD (Bandelow et al. 2008). In 
an epidemiological study, the concomitant use of BZD with an antidepressant increased the 
risk of hospitalization, both in psychiatric and non-psychiatric wards (Hawkins et al 2013). 
However, despite a reduction in prescriptions, 30% of PTSD patients still received BZD in 
2012 (Lund et al. 2012). 
Community-based epidemiologic studies indicate a lifetime prevalence of PTSD ranging 
from 8% to 12% (Kessler et al. 1995, Breslau et al. 1991), with at-risk individuals (victims of 
criminal violence, survivors of civilian disasters, combat veterans) showing a prevalence rate 
from 4% to 30% (Berger et al. 2012, Burri et al. 2014, Thomas et al. 2010, Winfield et al. 
1990, Shore et al. 1989, Jordan et al. 1991). 
1.2 
Investigational Product 
The investigational product (IP), BNC210, is a new chemical entity being developed by 
Bionomics Limited for the treatment of anxiety, and trauma and stressor-related, disorders. 
BNC210 is a negative allosteric modulator (NAM) of the alpha 7 nicotinic acetylcholine 
receptor, which represents a novel target for the treatment of these disorders. In vivo 
pharmacology has confirmed BNC210 efficacy in animal models of anxiety at low doses with 
a wide therapeutic index. There is an absence of the adverse effects particularly those 
associated with standard-of-care treatments for acute disorders, such as BZD and the 
antidepressants used as first line therapy for chronic disorders.

1.3 
Rationale 
 
 
This Phase II study is intended to assess the potential effect of BNC210 on the treatment of 
PTSD, a condition which is now classified in the DSM-5 as a Trauma and Stressor-Related 
Disorder rather than an Anxiety Disorder. Previous human studies have established safety, 
tolerability and demonstrated a reduction of CCK-induced anxiety in healthy subjects, as well 
as cognitive profiling. A Phase II imaging (fMRI) study 
 
 showed significant effects of 
BNC210 on anxiety-related brain activity and defensive behavior in drug-free GAD patients. 
In line with preclinical data demonstrating BNC210’s positive effects on fear extinction, and 
in order to expand the usefulness of BNC210 to other disorders related to anxiety, this 
molecule will be studied in PTSD patients where deficits in fear extinction are thought to 
contribute to the pathology of this disorder. Thus, PTSD is a condition with unmet medical 
needs, for which BNC210 may be of benefit.

3 INVESTIGATIONAL PLAN 
3.1 
Description of Overall Study Design and Plan 
This is a randomized, double-blind, parallel, placebo-controlled, multi-center study with a 
12-week, 4-arm treatment phase (placebo and BNC210).  Subjects will attend a Screening 
visit within 3 weeks before randomization to confirm eligibility. Approximately 192 subjects 
who fulfill the inclusion criteria and none of the exclusion criteria will be randomized on 
Day 1 using a 1:1:1:1 ratio. Subjects will then complete 12 weeks of their allocated treatment. 
The IP (total daily dose 300 mg, 600 mg or 1200 mg) or Placebo will be taken bid with food.  
Subjects will return to the clinical site at weekly or 2-weekly intervals to receive study 
medication, complete safety assessments and questionnaires.  Subjects are then requested to 
attend a post-study visit at 15 weeks (i.e., 3 weeks after the last treatment). 
The details are included in the Schedule of Assessments (Table 1). 
3.2 
Discussion of Study Design Including Choice of Control Groups 
This randomized, double-blind, placebo-controlled, Phase II study design was chosen to 
investigate whether BNC210 causes a decrease in symptoms of PTSD, as assessed by the 
CAPS-5 (National Centre for PTSD) compared to placebo. Subjects will be randomized to 
ensure that there are no order effects and to minimize bias. The study will be double-blind to 
ensure that the patients and clinic staff are unaware of the dosing assignment and to minimize 
the potential for bias in study assessments or in reporting of AEs.  
Subjects will still receive standard of care, even if randomized to placebo as their wellbeing 
will be monitored through application of various questionnaires and safety assessments.  
Subjects who received psychotherapy on a regular basis in the previous 3 months before 
inclusion into the study may continue to receive this care. A stable as needed (PRN) dose of 
benzodiazepine use will still be allowed during the study. 
3.3 
Selection of Study Population 
Each Investigator will identify potentially suitable patients from their active caseload.  A 
recruitment campaign may also be implemented to facilitate recruitment.  The campaign may 
consist of radio, print, and web based advertisements approved by the Human Research 
Ethics Committee (HREC) / Independent Review Board (IRB). The Principal or Co-
Investigator will be responsible for enrolling patients who are referred by an external clinician 
or respond to an advertisement.  All patients will be evaluated against the study eligibility 
criteria at Screening.  Only eligible patients will proceed through to the treatment phase. 
Patients must complete all protocol defined visits at study centers listed on the Clinical Trial 
Notification (CTN) form (Australia) and the Investigational New Drug (IND) application 
(USA).  
At the Screening visit, each patient will participate in the informed consent process and sign 
and date the patient informed consent form (PICF) before any procedures specified in this 
protocol are performed.

12 months prior to Screening and confirmed by follicle-stimulating hormone [FSH] 
levels in menopausal range at Screening). Sterilized male patients must be at least 1 
year post-vasectomy to be considered of non-child bearing potential. Acceptable 
forms of sterilization include bilateral tubal ligation, bilateral oophorectomy, and 
hysterectomy for women or vasectomy for men. 
Females and males of childbearing potential must agree to use two effective methods 
of contraception (double barrier contraception or hormonal contraceptive along with a 
barrier contraceptive) during the study and for 16 weeks following last study 
treatment.  Contraception that is deemed acceptable in this study includes the 
following:  
• Condoms  
• Hormonal (includes oral, injected, intrauterine, transdermal, or implanted).  
Females must be using hormonal contraceptives for at least 3 months prior to 
randomization and not change the contraceptive during the trial. 
Rhythm methods will not be considered as an effective method of birth control, 
however, abstinence may be allowed based on the opinion of the Investigator.  
Requirement for contraception can be waived in certain circumstances (i.e. same sex 
relationships) if approved by the Sponsor. 
Males must agree to not donate sperm for at least 16 weeks following last study 
treatment.

4.2 
Identity of Investigational Product 
BNC210 will be supplied in an amber single-use bottle as an 8 mL suspension in a vehicle.  
Placebo will be supplied in an amber single-use bottle as an 8 mL suspension of a suspension 
agent and yellow coloring agent in the same vehicle.  These treatments will be very similar in 
appearance. 
 
  
 
 
 
 
 
 
 
  
 
 
 
 
 
 
 
 
 
 
 
 
 
 
4.3 
Methods of Assigning Subjects to Treatment 
The IP in this study will only be administered to subjects included in the study following the 
procedures set out in the protocol.  Treatment will be randomly assigned using an IWRS. 
 
 
 patients will be randomly 
assigned to the four treatment groups in a 1:1:1:1 ratio until the close of randomization.  
4.4 
Selection of Dose in the Study 
The doses selected span the effective plasma exposure levels in the Phase II GAD patient 
study where significant results were obtained with single doses of 300 mg and 2000 mg 
BNC210.

4.5 
Selection and Timing of Dose for Each Subject 
Subjects will take 150 mg or 300 mg or 600 mg BNC210 or placebo bid, with food, as oral 
suspensions from single-use bottles for 12 weeks. Doses should be administered 
approximately 12 hours apart (+2 hours), with breakfast, and with an evening meal. Subjects 
must document all missed and partially administered doses in their Dosing Diary.  
4.6 
Dose Interruptions and Reductions 
Dose interruptions will be allowed following AEs. However, should an interruption of 3 or 
more days occur, approval from the Medical Monitor and Sponsor must be obtained prior to 
re-commencing study treatment. Dose reductions will not be allowed. 
4.7 
Blinding 
This study will be double-blind with the subject, Investigator, and rater being unaware of the 
treatment the subjects will receive. 
4.8 
Emergency Unblinding of Study Subjects 
The Investigator should contact the Medical Monitor to discuss the need to break the blind. In 
the event that an emergency unblinding is required and the Medical Monitor is unavailable, 
the Investigator will be able to unblind via the Interactive Web Response System (IWRS). 
Refer to the IWRS User Guide for further instructions. The Sponsor and Medical Monitor 
must be notified within 24 hours of any emergency unblinding. Blinding codes should only be 
broken in emergency situations for reasons of subject safety and when knowledge of the 
treatment assignment will impact the clinical management of the subject. Every reasonable 
attempt should be made to complete the Early Termination Visit prior to unblinding, as 
knowledge of the treatment arm could influence subject assessment. In all cases, the reasons 
and rationale for unblinding will be documented in writing and maintained in the study file. 
4.9 
Supply, Packaging and Labeling of the Investigational Product 
The IPs will be packaged in treatment kits according to Good Manufacturing Practice (GMP) 
and all local regulations. They will be labeled in accordance with Australian and USA 
requirements. Treatment kits will be supplied to each study site with an acknowledgement of 
receipt form. The manufacturer will provide a certificate of analysis and a batch release 
certificate for IPs used in the study. 
The Investigator, or Designee, will only dispense treatment kits to subjects enrolled in this 
study. Kits will be allocated using the IWRS. All dispensing episodes, including the kit and 
batch number, will be captured in IWRS. Each subject will maintain a Dosing Diary where 
the time and date of each dose is recorded. These diaries will be returned at each visit after 
Baseline and a new diary issued. The data will then be captured in the eCRF.

4.10 Storage of the Investigational Product 
Prior to dispensing, all IP must be stored in a secure and locked storage area with limited 
access, under monitored, temperature controlled conditions. The Pharmacist or Designee will 
be responsible for the correct storage and handling of the IP, the details of which are provided 
in the BNC210.007 Pharmacy Manual. Deviations from the storage requirements, including 
corrective action, must be documented.   
Once the subjects have received their treatment kits, the clinical site will instruct them on the 
correct storage requirements. 
4.11 Accountability, Reconciliation and Return of the Investigational Product 
The Investigator must maintain complete and current IWRS dispensing and inventory 
records.  The Investigator is accountable for all IP supplied by the Sponsor. The IWRS logs 
must be printed at the conclusion of the study and will contain the following information: 
• Date of receipt. 
• Number of kits received. 
• Batch number(s). 
• The identification of the subject to whom the kit was dispensed. 
• The date(s) and quantity of kits dispensed to the subject. 
• The cumulative total of kits at site. 
• Kits damaged, destroyed, or returned. 
Supplies will be shipped to the investigational site as needed. The Monitor will complete drug 
accountability during routine monitoring visits. 
At the completion or termination of the study, final drug accountability and reconciliation 
will be completed and any discrepancies must be investigated and their resolution 
documented.  All full, partially full, and empty bottles of IP must be returned to the 
Pharmacy, Manufacturer or Sponsor for destruction, and the appropriate form sent to the 
Sponsor. 
Please refer to the Pharmacy Manual for further details and the storage, handling, and 
dispensing of IP. 
4.12 Prior and Concomitant Therapy 
Use of any investigational drug within 30 days prior to Screening and at any point during the 
study is prohibited. 
Inducers of cytochrome P450 3A4 should not be used within one month of Screening and 
their use is prohibited during the study. This includes, but is not limited to: carbamazepine, 
phenytoin, oxcarbazepine, barbiturates, phenobarbital, butalbital, St. John's wort, rifampicin, 
rifabutin, efavirenz, nevirapine, pioglitazone, troglitazone, corticosteroids by the systemic 
route.   
Moderate – strong inhibitors of cytochrome P450 3A4 should not be used within two weeks 
of Screening and their use is prohibited during the study.  These include grapefruit juice, 
verapamil, diltiazem, fluvoxamine, fluconazole and itraconazole and HIV antivirals.

Subjects that are under consideration for the study and are being treated with a psychiatric 
medication that is not permitted under inclusion criterion 4, must have discontinued the 
medication for at least two weeks prior to Screening and be titrated off their treatment in 
accordance with current prescribing guidelines. The withdrawal of psychiatric medication is 
at the discretion of the subject in consultation with their primary physician and falls outside 
the scope of this study protocol. 
Concurrent use of no more than one SSRI (fluvoxamine is excluded) or SNRI within the 
licensed prescribing dose range, is permitted from Screening through Week 15.  Subjects 
must have been on a stable dose for at least 3 months prior and through Screening and no 
dose adjustments are allowed on study,  
The use of any other psychiatric medication is prohibited during all stages of the study. This 
includes, but is not limited to, antidepressants / anxiolytics not otherwise listed under 
inclusion criterion 4, mood stabilizers, stimulants, antipsychotics, hypnotics, and 
acetylcholinesterase inhibitors. 
Limited use of BZD is permitted on a PRN basis as rescue medication. The frequency of use 
must not exceed 2 times per week and the total dose in diazepam equivalents must not exceed 
30 mg/day.  
The use of antihistamines as a sleep medication is permitted. However, subjects must avoid 
the use of antihistamines for 12hrs prior to visits where cognitive function is assessed 
(Baseline, V3, and V7). 
Subjects must not have been treated with alprazolam or flunitrazepam for 3 months prior to 
Screening and the use of these medications in prohibited during the study. 
The use of non-prescription medications (including herbal medications) will be discouraged 
during the course of the study. Prescription medications should be limited and avoided if 
possible, but will be allowed where clinically indicated, e.g. for treatment of AEs or pre-
existing medical conditions documented at Screening.  The use of all concomitant medication 
(including non-prescription medications) must be recorded for each subject over the duration 
of the study. The indication for use, generic name of the drug, dosage, and date of 
administration will be recorded. 
Ongoing long-term supportive counseling or intensive regular psychotherapy is allowed only 
if the subject commenced therapy > 3 months prior to Screening and is willing to continue 
therapy at the same frequency through Week 15 or study withdrawal, whichever occurs last. 
If a medication or treatment is administered that is in breach of these restrictions, the 
Sponsor’s Medical Monitor must be promptly notified in order to assess the subject’s 
suitability for continued study participation. 
4.13 Treatment Compliance 
Treatment compliance will be assessed by the following procedures: 
• Blood sampling for the assessment of BNC210 concentrations at Screening and three 
times during treatment. 
• Doses administered based on the number of IP bottles returned used and unused.

4.14 Measures to Minimize Bias 
4.14.1 Randomization Procedures 
At Screening, subjects will be allocated a sequential five-digit study subject identification 
number (SSID), the first two numbers of which denote the study center. This is followed by 
the sequential three-digit subject number. As an example, the first subject screened at site 10 
will be allocated the SSID 10-001. Subjects will retain the same SSID for the duration of the 
study. An IWRS will allocate a randomization number at the baseline visit but the number 
will not be used for subject identification purposes. 
Data associated with subjects that fail screening will not be entered into the eCRF.  
 
 patients will be randomly 
assigned to the four treatment groups in a 1:1:1:1 ratio until the close of randomization.  
The IWRS vendor will be supplied with a validated randomization list by an Independent 
Statistician. 
4.14.2 Maintenance of Consistent Behaviors 
Over the course of the study, subjects will be counseled on the importance of maintaining 
consistent behaviors. This includes limiting any change to alcohol or tobacco use, dietary 
intake, and sleep patterns when compared to baseline. Subjects will also be encouraged to 
attend study visits at the same time of day to avoid possible diurnal variation in measurement 
responses.  
Cognitive function must be assessed at the same time during each visit (+ 1hr of baseline 
assessment start time). The use of rescue benzodiazepines, recreational drugs (e.g. cannabis, 
amphetamines), antihistamines, and excessive alcohol use within 12hrs prior to the 
assessment of cognitive function should also be avoided. Subjects who have used these 
medications / drugs within 12hrs should be invited to re-attend the following day where the 
visit can be completed. Should a subject refuse an invitation to re-attend, the Investigator 
should proceed with the assessment making a note within the CANTAB system indicating the 
results may be influenced by drug or medication use.

5.11 Unscheduled Visits 
Subjects may attend an unscheduled visit at any time. All assessments completed during an 
unscheduled visit must be captured in the electronic case report form (eCRF). This 
includes the results of all pathology tests scheduled by the Investigator. 
Visits scheduled due to an increase in ALT or AST >3 x ULN (see Section 6) must be 
captured as an unscheduled visit.  
A visit with a Subject’s primary physician (i.e. not a study Investigator) is not considered 
an unscheduled visit. Similarly, hospital admissions due to SAEs are also not considered 
unscheduled visits. Assessments completed by external institutions should not be entered 
into the eCRF.  
5.12 Re-screening of Study Subjects. 
In the event that a subject fails a clinical laboratory or ECG screening assessment, that 
assessment can be repeated once only. The repeat assessment must be completed within 
the allowed screening period (21 days + 2 days of Baseline) for eligibility purposes. If the 
repeat assessment cannot be completed within the screening period, the subject must be re-
screened in entirety. Subjects who fail any other screening assessment must be screen-
failed.  Subjects can be re-screened once only.

6 WITHDRAWAL OF SUBJECTS OR TERMINATION OF THE 
STUDY 
Subjects should be encouraged to complete all study assessments. However, subjects may 
withdraw consent to participate in this study at any time and for any reason without penalty or 
loss of benefits to which they were otherwise entitled.  The Sponsor or the Investigator may 
withdraw subjects at any time for safety or administrative reasons.  If a subject is withdrawn 
from the study or treatment, the reason will be recorded on the eCRF and the Sponsor notified 
promptly. 
Subjects who are withdrawn from treatment early due to SAEs must be followed-up and 
provided appropriate medical care until their signs and symptoms have remitted or stabilized, 
until the subject is lost to follow-up, or until the post study visit, whichever comes last. 
Subjects who experience an SAE that is deemed to be related to the IP will have treatment 
withdrawn. 
A subject may be withdrawn from the study if any of the following occur during the study: 
1. Subject withdraws consent; 
2. AE makes the continuation of the subject impossible or inadvisable; 
3. Pregnancy; 
4. Subject is lost to follow-up; 
5. Subject discovered after enrollment not to have met the protocol inclusion criteria; 
6. Subject refuses to comply with required study procedures; 
7. Use of any restricted medication (including experimental) or therapy; 
8. The study Sponsor terminates the Investigator Site or the study. 
Subjects are to have treatment withdrawn by the Investigator for any of the following: 
• Any new suicidal behavior since Screening, as disclosed by the subject during 
administration of the C-SSRS. 
• Any suicidal ideation with intent (yes to item 4 and / or 5) since Screening, as 
disclosed by the subject during administration of the C-SSRS. 
• A score > 4 on item 10 of the MADRS. 
• Prolonged QTcF interval: Subjects with prolonged QTcF interval of ≥500 msec 
(confirmed after triplicate repeated measurement at least 2 minutes apart) should be 
discontinued from treatment either temporarily or permanently and monitored for 
safety by the Investigator. 
• Elevated serum transaminases (LFT abnormalities) confirmed to be: 
o ALT or AST >5 x ULN; 
o ALT or AST >3 x ULN for more than 2 weeks; 
o ALT or AST >3 x ULN and total bilirubin >2 x ULN (Hy’s Law); or 
o ALT or AST >3 x ULN with the appearance of worsening of fatigue, nausea, 
vomiting, right upper quadrant pain or tenderness, fever, rash or eosinophilia. 
Should a subject experience an elevation of ALT or AST >3 x ULN, the subject should return 
to the clinic for repeat LFT testing every 3 to 5 days while on study drug until the ALT or 
AST returns to baseline, becomes stable, or reaches any of the stopping rules for LFT 
abnormalities.

All subjects that have treatment withdrawn prior to Visit 7 (week 12) for any reason should 
return to the study site within 10 calendar days of last dose and an Early Termination (ET) 
Visit completed. Should treatment be withdrawn during a visit, that visit becomes the ET 
Visit. After withdrawal from treatment, subjects will be asked to return to the study site at the 
regular protocol-defined visit schedule (calculated from Day 1) where only the following 
assessments will be completed as per the regular schedule of assessments: 
• 
CAPS-5. 
• HAM-A. 
• 
MADRS. 
• PCL-5. 
• 
CANTAB Cognitive Assessment. 
• SDS. 
• AQoL-8D. 
• PSQI. 
• CGI-I/CGI-S. 
• C-SSRS 
• PGI-I/PGI-S. 
• AE recording. 
• Record concomitant medication use. 
• Record of nicotine use. 
The measurement of vital signs, the collection of pathology samples (including the BNC210 
compliance, 
 samples), and the completion of ECGs during 
visits that occur after the treatment withdrawal are not required unless clinically indicated. 
The timing of the post treatment withdrawal visits are calculated from Day 1 and should 
follow the study schedule of assessments through Visit 7 (week 12) as captured in Table 1. 
During this period, subjects must adhere to all concomitant medication and therapy 
restrictions as captured in protocol section 4.11. Those subjects unable to adhere to the 
medication and therapy restrictions post treatment withdrawal must be withdrawn from the 
study completely and attend an Early Termination Visit within 10 calendar days of their last 
dose.  No further study visits are required. Subjects are also free to withdraw from the study 
at any time and without prejudice to further care according to standard clinical practice.

7 EFFICACY VARIABLES 
7.1 
Definitions of Variables 
All the assessments/questionnaires below will be assessed at time-points as captured in the 
Schedule of Assessments (Table 1). 
7.1.1 
Clinician-Administered PTSD Scale for the DSM-5 (CAPS-5) 
The CAPS-5 is a 30-item structured interview used to diagnose PTSD and assess PTSD 
symptoms over the past week. Information about the frequency and intensity of each item is 
combined into a severity rating, and the CAPS-5 total severity is calculated by adding the 
severity scores for the 20 PTSD symptoms in the DSM-5 (National Centre for PTSD). The 
severity of PTSD is rated from 0 (absent) to 4 (extreme/incapacitating).  
7.1.2 
PTSD Checklist for DSM-5 (PCL-5) 
The PCL-5 is a 20-item self-report assessment of the 20 DSM-5 symptoms of PTSD 
(National Centre for PTSD). Each symptom is rated on a scale from 0 (not at all) to 4 
(extremely).  
7.1.3 Clinical Global Impression scales – Improvement and Severity (CGI-I/CGI-S) 
The CGI-S is a rating scale designed to assess the severity of the subject’s symptoms, and the 
CGI-I is designed to assess the change in the subject’s condition since the initial assessment. 
Severity is rated on the CGI-S from 1 (normal, not at all ill) to 7 (among the most extremely 
ill of subjects). The changes in the subject’s condition are rated on the CGI-I from 1 (very 
much improved) to 7 (very much worse). 
7.1.4 
Patient Global Impression Scales – Improvement and Severity (PGI-I/PGI-S) 
The PGI-S is a self-rating scale designed to assess the severity of the subject’s symptoms, and 
the PGI-I is designed to assess the change in the subject’s condition since the initial 
assessment. Severity is rated on the CGI-S from 1 (normal) to 4 (severe). The changes in the 
subject’s condition are rated on the CGI-I from 1 (very much better) to 7 (very much worse). 
7.1.5 
Assessment of Quality of Life (AQoL-8D) 
The AQoL-8D is a 35 question self-rating scale designed to assess a subject’s quality of life 
on the following eight dimensions; Independent Living, Happiness, Mental Health, Coping, 
Relationships, Self-Worth, Pain and the Senses. The scale takes approximately 5 minutes to 
complete.  
7.1.6 
Hamilton Anxiety Rating Scale (HAM-A) 
The HAM-A is an interview questionnaire that measures severity of anxiety symptoms based 
on 14 parameters, including anxious mood, tension, fears, insomnia, somatic complaints and 
behavior during the interview (Hamilton, 1959). It takes approximately 15-20 minutes to 
complete and each parameter is rated on a scale of 0 (not present) to 4 (very severe).

7.1.7 
Montgomery-Asberg Depression Rating Scale (MADRS) 
The MADRS is a 10-item self-diagnostic and clinician-rated questionnaire to measure the 
presence and severity of depressive episodes and includes the following symptoms: 1) 
apparent sadness; 2) reported sadness; 3) inner tension; 4) reduced sleep; 5) reduced appetite; 
6) concentration difficulties; 7) lassitude; 8) inability to feel; 9) pessimistic thoughts; and 10) 
suicidal thoughts (Williams and Kobak, 2008). The rater must decide whether the rating lies 
on defined scale steps (0, 2, 4, 6) or between them (1, 3, 5). 
7.1.8 
CANTAB Cognitive Assessment 
The CANTAB cognitive assessment is a battery of tests designed to detect both cognitive 
impairment and enhancement. The battery will measure cognitive function through assessing 
sustained attention, episodic memory, working memory and executive function. All tests will 
be completed electronically using iPads. The test battery will take approximately 20-25 
minutes to complete. The CANTAB cognitive assessment must be completed at the same 
time during each visit (+ 1hr of baseline assessment start time). 
 
A Paired Associates Learning (PAL) task will be used to assess episodic memory. During the 
test, boxes are displayed on the screen and open in turn to reveal a number of patterns. 
Participants are instructed to try to remember the location in which each pattern was shown. 
After all the boxes have been opened, each pattern is then shown in the center of the screen in 
a randomized order, and the participant touches the box in which the pattern was located. If 
an error is made, all the patterns are re-presented to remind the participant of their locations. 
As the test progresses so the stages become more difficult as the number of patterns to be 
remembered increases, up to a maximum of 8 patterns. For participants who fail to complete 
all levels, an adjusted total is calculated that allows for errors predicted in the stages that were 
not attempted. The key outcome measures for this task are total errors and first trial memory 
score. 
 
A Spatial Working Memory (SWM) task will be used to assess the ability of the subject to 
retain spatial information and manipulate it in working memory. It is a self-ordered task that 
also gives a measure of strategy. A number of colored boxes are presented on the screen, and 
the computer hides a token in these boxes one at a time. The participant is instructed to touch 
the boxes in turn to search for the token that has been hidden. When a token is found it should 
be placed in a home area on the right side of the screen. The participant then searches for 
more tokens until the same number of tokens as the number of colored boxes has been found. 
The key task instruction is that the computer will never hide a token in the same colored box 
twice in the same problem. As the test progresses, so it becomes more difficult. The key 
outcome measures for this task are between errors and strategy. 
 
A Rapid Visual Information Processing (RVP) task will be used to assess sustained attention, 
outputting measures of response accuracy, target sensitivity and reaction times. For the RVP 
task, single digits appear in a pseudo-random order at a rate of 100 digits per minute in box in 
the center of the screen. Subjects must detect a series of 3-digit target sequences (e.g. 3-5-7; 
2-4-6; 4-6-8) and respond by touching the button at the bottom of the screen when they see 
the final number of the sequence. Nine target sequences appear every minute. Key outcome 
measures include target sensitivity and reaction times.

Factors that could influence the cognitive function assessments must be captured within the 
CANTAB system. This includes, but is not limited to, drug and medication use within 12hrs 
of assessment, lack of sleep, and failure to understand the test requirements. Please refer to 
the CANTAB User Manual for details on how to capture this information. 
7.1.9 
Sheehan Disability Scale (SDS) 
The SDS is a rating scale designed to measure impairment in three domains: work/school, 
social life, and family life/home responsibilities. Each item is rated on a scale of 0 (not at all) 
to 10 (extremely), for a total score of 0 to 30.  
7.1.10 Pittsburgh Sleep Quality Index (PSQI) 
The PSQI is a questionnaire consisting of 19 questions designed to assess the following 
7 components of sleep quality: subjective sleep quality, sleep latency (i.e., how long it takes 
to fall asleep), sleep duration, habitual sleep efficiency, sleep disturbances, use of sleeping 
medication, and daytime dysfunction over the previous month. Each question is weighted on 
a scale from 0 to 3 and a global score is obtained, with lower scores correlating with better 
sleep quality.

9 SAFETY VARIABLES 
9.1 
Safety Endpoint(s) 
Safety will be assessed during the study through physical examination, urinalysis, vital signs, 
ECG, laboratory tests, C-SSRS and continuous AE reporting, as outlined in the Schedules of 
Assessment (Table 1). 
9.2 
Physical Examination 
A complete physical examination will be performed at Screening, Visit 7 (Week 12), and 
Early Termination. A complete physical examination will include assessments of general 
appearance; skin and lymphatics; eyes; ears; nose; throat; cardiovascular system; respiratory 
system; abdomen/gastrointestinal system; musculoskeletal and neurological systems.  Other 
body systems may also be examined as required. 
An abbreviated physical examination will be performed at Visit 2 (Week 2), Visit 4 (Week 6), 
and Post Study (Week 15). An abbreviated physical examination will include assessments of 
eyes, 
ears, 
nose, 
throat, 
cardiovascular 
system, 
respiratory 
system, 
and 
abdomen/gastrointestinal system. Other body systems may also be examined as required. 
Clinically significant changes from first dose of Investigational Product will be recorded as 
AEs. 
Height and weight will be recorded in centimeters (cm) and kilograms (kg), respectively and 
only at Screening. Weight is measured with subjects wearing light clothing without shoes. 
9.3 
Vital signs 
Vital signs will be measured at every visit from Screening to Week 15 (Post Study Visit). 
Vital signs include systolic and diastolic blood pressure, pulse rate, respiration rate and body 
temperature.  Blood pressure and heart rate will be measured in a sitting position after resting 
for 5 minutes.  Systolic blood pressure (SBP) and diastolic blood pressure (DBP) should be 
measured in millimeters of mercury (mmHg), heart rate in beats per minute, respiration rate 
in breaths per minute and temperature (oral) in degrees Celsius (°C). 
9.4 
12-lead ECGs 
ECGs will be taken at time-points as indicated in the Schedule of Assessments (Screening, 
Visit 2, Visit 4, Visit 7 / ET). 
ECG recordings will be taken in triplicate, with at least a 2-minute break between each test.  
The QTcF value will be calculated as the mean of the 3 ECG readings. One repeat is allowed 
for screening purposes if abnormal findings are observed. The repeat must also be completed 
in triplicate. 
The subject must be resting in a semi-supine or supine position for at least 5 minutes prior to 
performing the ECG.  The same ECG machine should be used for all recordings from an 
individual subject, where possible.  ECGs will be read by the Investigator or designated 
physician at the unit.  Machine-read automated ECG intervals (PR, QRS, QT and HR), and 
calculated RR intervals will be captured in the eCRF and any other abnormalities noted.  
QTcF values will be derived from the data available and the average QTcF will be used when 
assessing eligibility and treatment withdrawal.

     Page 47 of 62 
 
For safety monitoring purposes, the Investigator or Designee must review, sign and date all 
ECG tracings.  Paper copies will be kept at the study center with the subject's clinical file as 
part of the permanent record.  The ECG intervals and interpretation will be recorded on the 
appropriate eCRF form. 
Paper ECG recordings should be photocopied and maintained as a permanent source 
document.  The Sponsor reserves the right to request copies of paper ECG recordings for 
independent cardiology review. 
9.5 
Clinical Laboratory Tests 
Blood samples for laboratory assessments will be taken at Screening, Visit 2, Visit 4, Visit 7 / 
ET. 
Laboratory data obtained at Screening will be used as baseline in the safety analyses.  Safety 
Laboratory Data include: 
• Complete blood count (CBC):  hemoglobin, hematocrit, red blood cell (RBC) count, 
MCV, white blood cell (WBC) with differential (neutrophils, lymphocytes, 
monocytes, eosinophils, basophils), and platelet count.  
• Chemistry panel: Albumin, ALP, ALT (SGPT), aspartate aminotransferase (AST, 
SGOT), gamma glutamyltransferase (GGT) bicarbonate, total and direct bilirubin, 
BUN or plasma urea, corrected calcium, chloride, sodium, creatinine, eGFR 
(Cockcroft Gault), glucose, potassium, uric acid and total protein. 
• CRP. 
• FSH on postmenopausal females. 
• Urinalysis: specific gravity, pH, protein, glucose, ketones, bilirubin, blood, nitrite, and 
leukocyte esterase. 
o Specimens with abnormal Protein, WBC or RBC will be submitted for 
microscopy testing and reporting on WBCs, RBCs, epithelial cells, casts, 
crystals, yeast, and bacteria.  Specimens with elevated WBC may be submitted 
for microbiological testing for infection. 
Screening blood tests include: 
Serology: hepatitis (HepB surface antigen, anti-HCV), HIV.  
Pregnancy Tests 
A serum pregnancy test will be performed on all females of childbearing potential at 
Screening and a urine pregnancy test on Day 1 before randomization and at Visit 7 / ET.

9.6 
Columbia Suicide Severity Rating Scale (C-SSRS) 
The C-SSRS is a suicidal ideation rating scale designed to identify behaviors that may be 
indicative of a patient’s intent to commit suicide. The scale is administered via a semi-
structured interview and measures both passive and active suicidal ideation and the intensity 
and duration of the ideation. Both suicidal and non-suicidal self-injurious behavior is also 
assessed. 
9.7 
Adverse Events (AEs) 
The Principal Investigator and clinical facility staff are responsible for detection, recording, 
and reporting of events that meet the criteria and definition of various AEs as listed below. 
AEs will be recorded from first administration of IP through Week 15 (Post Study Visit). The 
Principal Investigator and clinical facility staff are responsible for detection, recording and 
reporting of pregnancy and appropriate follow up. 
9.7.1 
Definitions 
An AE is any untoward medical occurrence in a patient or clinical investigational subject 
administered a pharmaceutical product and which does not necessarily have to have a causal 
relationship with this 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 a 
medicinal product, whether or not related to the medicinal product. 
AEs will not include: 
• A medical or surgical procedure such as surgery, endoscopy, tooth extraction, or 
transfusion (although the condition that leads to the procedure may be an AE).  
• A pre-existing disease or condition present at the start of the study that does not 
worsen during the study  
• Any situation where an untoward medical occurrence has not occurred (for example, 
hospitalizations for cosmetic elective surgery or social admissions)  
• An overdose of either the IP or a concurrent medication without any resulting signs or 
symptoms. 
9.7.2 
Grading of Adverse Events 
The maximum intensity of an AE during a day should be graded according to the definitions 
below and recorded as indicated in the eCRF.  If the intensity of an AE changes over a 
number of days, then separate entries should be made with distinct onset dates. 
The severity of each AE will be categorized using the following criteria: 
• Grade 1 (Mild):  usually transient; requires no special treatment and does not interfere 
with the subject’s daily activities.  No limitation in daily activity. 
• Grade 2 (Moderate):  produces a low level of inconvenience to the subject and may 
interfere with daily activities.  These events are usually ameliorated by simple 
therapeutic measures.  Some limitation in daily activity. 

Bionomics Limited 
Version 4.0 
Protocol No.: BNC210.007 
Date: 30-May-2018 
CONFIDENTIAL  
     Page 49 of 62 
 
• Grade 3 (Severe):  interrupts daily activity and requires systemic drug therapy or other 
medical treatment.  Unable to perform daily activity. 
An AE that is assessed as severe should not be confused with a SAE. Severity is a category 
utilized for rating the intensity of an event; and both AEs and SAEs can be assessed as severe. 
An AE is defined as ‘serious’ when it meets one of the pre-defined serious outcomes as 
described in Section 9.8. 
9.7.3 
Causal Relationship to Investigational Product  
The relationship of an AE to the IP is a clinical decision by the Investigator based on all 
available information at the time of reporting. The causal relationship must be graded as 
follows: 
• Not related: a reaction for which sufficient information exists to indicate that the 
etiology is unrelated to the study drug; the subject did not receive the study 
medication or the temporal sequence of the AE onset relative to administration of the 
study medication is not reasonable or the event is clearly related to other factors such 
as the ’s clinical state, therapeutic intervention or concomitant therapy. 
• Possible: a clinical event, including laboratory test abnormality, with a reasonable 
time sequence to administration of the drug but which could also be explained by 
concurrent disease or other drugs or chemicals, information on drug withdrawals may 
be lacking or unclear. 
• Probable: a clinical event including laboratory test abnormality, with a reasonable 
time sequence to administration of the drug, unlikely to be attributed to concurrent 
disease or other drugs or chemicals and which follows a clinically reasonable response 
on withdrawal (de-challenge): re-challenge information is not required to fulfill this 
definition. 
• Definite: a reaction that follows a reasonable temporal sequence from administration 
of the drug or in which the drug level has been established in body fluids or tissues, 
that follows a known or expected response pattern to the suspected drug, and that is 
confirmed by improvement on stopping or reducing the dosage of the drug, and 
reappearance of the reaction on repeated exposure (re-challenge). 
9.7.4 
Documentation of Adverse Events by the Investigator 
When an AE occurs, it is the responsibility of the Principal Investigator to review all 
documentation (e.g. progress notes, laboratory, and diagnostics reports) relative to the event. 
The Principal Investigator will then record the AE on the AE eCRF. Additional reporting 
requirements for an AE meeting serious criteria are discussed in Section 9.8 below. The 
Principal Investigator will attempt to establish a diagnosis of the event based on signs, 
symptoms, and/or other clinical information. In all cases, when available, the diagnosis 
should be reported as the event and not the individual signs/symptoms.  
9.7.5 
Laboratory Test and other Test Abnormalities as Adverse Events 
Abnormal assessments (e.g., ECGs and vital signs) that are judged by the Principal 
Investigator as clinically significant or if the abnormal assessment results in clinical sequelae 
will be recorded as AEs.  
 

Bionomics Limited 
Version 4.0 
Protocol No.: BNC210.007 
Date: 30-May-2018 
CONFIDENTIAL  
     Page 50 of 62 
 
Laboratory abnormalities will be reported by the Investigator as AEs if the abnormality is 
considered clinically significant or if the abnormality results in clinical sequelae.  
Clinically significant abnormal laboratory findings or other abnormal assessments that are 
detected during the study or are present at baseline and significantly worsen following the 
first administration of IP will be reported as AEs.  
The Principal Investigator and Co-Investigators will exercise their medical and scientific 
judgment in deciding whether an abnormal laboratory finding or other abnormal assessment 
is clinically significant. 
9.8 
Serious Adverse Events (SAE) 
An SAE is any AE that: 
• Results in death, or 
• Is life-threatening, or 
• Requires inpatient hospitalization or prolongation of existing hospitalization, or 
• Results in persistent or significant disability/incapacity, or 
• Is a congenital anomaly/birth defect. 
Important medical events that may not result in death, be life-threatening, or require 
hospitalization may be considered SAEs when, based upon appropriate medical judgment, 
they may jeopardize the subject and may require medical or surgical intervention to prevent 
one of the outcomes listed in this definition. 
The term ‘life-threatening’ in the definition of ‘serious’ refers to an event/reaction in which 
the subject was at immediate risk of death at the time of the event/reaction; it does not refer to 
an event/reaction, which hypothetically might have caused death, if it were more severe.  
Any planned procedures that require admission to hospital for compliance with this protocol 
as well as any planned elective procedures are not considered SAEs (unless the underlying 
condition has worsened or the procedure results in a worsening of the subject’s condition).  In 
addition pregnancy that occurs during the course of the study or absence of a treatment effect 
will also not be considered to be an SAE. 
9.8.1 
Reporting for Serious Adverse Events (24 Hours) 
SAEs must be followed until their signs and symptoms have remitted or stabilized, until the 
subject is lost to follow-up, or until Week 15 (Post Study Visit), whichever comes last. 
Investigators are not obligated to actively seek SAEs after Week 15 (Post Study Visit). 
However, if an Investigator learns of any SAEs that occur after study participation for a 
subject has concluded and the event is deemed relevant to the use of study drug, it should be 
promptly reported. 
AEs meeting serious criteria MUST be reported promptly to the designated Clinical Research 
Organization (CRO) Safety Desk within 24 hours, and to the HREC/IRB in accordance with 
their safety reporting policy. The SAE report form will always be completed as thoroughly as 
possible with all available details of the event and signed by the Principal Investigator (or 
Designee). If the Principal Investigator does not have all information regarding an SAE, 
he/she will not wait to receive additional information before reporting the event. The SAE 
report form will be updated when additional information is received.

The Principal Investigator will always provide an assessment of causality at the time of the 
initial report as described in Section 9.7.3.  
Facsimile or email transmission of the SAE report form is the preferred methods to transmit 
this information to the designated CRO Safety Desk. In rare circumstances notification by 
telephone is acceptable, with a copy of the SAE report form sent by overnight mail.  
Initial notification via the telephone does not replace the need for the Principal Investigator to 
complete and sign the SAE report form within the outlined time frames. The Sponsor will 
provide a list of project contacts for SAE receipt, fax numbers, telephone numbers, and 
mailing addresses 
The Principal Investigator, or responsible person according to local requirements, will comply 
with the applicable local regulatory requirements related to the reporting of SAEs to 
regulatory authorities and the HREC/IRB. 
9.9 
Safety Review Committee 
An independent Safety Review Committee will be established to monitor subject safety 
throughout the study. The meetings will occur approximately every 6 months and will review 
all safety data including vitals signs, ECG, pathology results, physical examinations, C-
SSRS and continuous AE reporting.

10 DATA MANAGEMENT AND STATISTICS 
10.1 Data Collection 
Designated investigator staff must enter all information required by the Protocol into the 
eCRF. Monitors will review the eCRFs for completeness and accuracy and instruct site 
personnel to make any required corrections or additions.  All data will be collected in an 
eCRF with controlled access and audit trail. 
10.2 Data Management and Quality Control 
eCRF data will be validated by a series of programmed checks and listing reviews as defined 
in the Data Validation Plan and in accordance with the Data Management group’s own 
internal standard operating systems (SOPs) that have been reviewed and approved by the 
study Sponsor. Queries will be either automatically generated or manually added to the eCRF 
for resolution by the site. Responses to queries will be entered directly into the eCRF by site 
staff. Quality control audits of all key safety and efficacy data in the database are made prior 
to locking the database.  
Concomitant medications entered into the database will be coded using the World Health 
Organization Drug Dictionary (WHODRUG) terminology. 
Medical history/current medical conditions and AEs will be coded using the Medical 
dictionary for regulatory activities (MedDRA) terminology. 
The eCRFs will be reviewed and approved by the study Sponsor. The eCRFs and associated 
programmed validation checks and listings will undergo User Acceptance Testing prior to 
being released for use in the study. All access to the eCRF is controlled by user permissions 
and reviewed via audit trail. 
Data Retention procedures will be conducted in accordance with the Data Management 
group’s own internal SOPs that have been reviewed and approved by the study Sponsor. All 
eCRF and biometrics study related data to be archived will be maintained in the Biometrics 
Trial Master File. 
Data will be retained in the electronic Biometrics Trial Master file for a period of 15 years 
after release of any related batch of finished product in accordance with the Data 
Management group’s own internal SOPs. Bionomics Ltd, the study Sponsor will retain 
CDISC files and in addition the following documents will be provided by the Data 
Management group for inclusion in the Trial Master File, and other documents would most 
likely be provided from other sources: 
• Blank copy of approved eCRF (including AE forms) 
• Training records – eCRF system 
• Relevant correspondence 
• pdf of completed CRFs (including audit trail, discrepancies and AEs) 
10.3 Statistical Considerations 
The Biostatistical Department of 
  will be responsible for the 
analysis of demographic, safety, efficacy and compliance data. 
 
 using SAS® software version 9.3 (or higher) (SAS Institute Inc.,

Cary, NC, USA).  A detailed statistical analysis plan (SAP) will be compiled before data base 
lock describing the methods used for the statistical analyses. 
10.4 Sample Size 
Sample size estimation is based on the following: 
 
 
 
 
 
 
 
 
 
  
 
 
.  With the 
level of significance set to 0.05 and a 2-sided test, a sample size of 36 subjects per arm is 
required to achieve a power of 80%.  For PTSD patients a relatively high withdrawal rate is 
anticipated, therefore the sample size was increased by 33% to 48 per arm (=1.33x36) 
(Hoskins et al. 2015, Marshall et al. 2001; Marshall et al. 2007; Tucker et al. 2001). Because 
this is a Phase II study the level of significance will be 0.05 with no adjustment for multiple 
comparisons. 
10.4.1 Review of Sample Size calculation 
 
 
 
 
 
 
 
 
10.5 Statistical Methods 
Descriptive statistics will be supplied according to the nature of the criteria where 
Quantitative variables will be presented as follows: sample size, arithmetic mean, SD, 
median, minimum and maximum.  Qualitative variables will be presented as follows: sample 
size, frequencies and percentages per category 
10.6 Analysis Populations and/or Subsets 
The Intent-to-treat (ITT) population will comprise all randomised subjects; analysed as per 
randomised treatment.  The Modified ITT (mITT) population will be those subjects from the 
ITT population who received at least one dose of study medication.  The mITT population 
will be used for all efficacy analyses, tabulations, and listings.

The safety population will comprise all randomised subjects who receive at least one dose of 
study medication and will be analyzed as per treatment received.  The safety population will 
be used for all safety analyses and listings.  
The analysis sets will be validated during a blind review meeting. 
10.6.1 Description of the Populations 
A summary table with the description of the number of subjects in each analysis set, the 
number of subjects who completed the study, and the number of subjects who discontinued 
classified by reason of withdrawal, will be prepared.  Corresponding individual listings will 
be prepared. 
Listings with end of study status and visit dates will also be prepared. 
10.7 Demographics and Baseline Characteristics 
The following analysis will be performed on the Randomized (mITT) set. 
The subject’s demographic characteristics and baseline characteristics (including the 
applicable questionnaires) will be summarized by treatment and overall. Details of drug 
dosing will be listed by subject. 
10.8 Protocol Deviations 
A protocol deviation is defined as any intentional or unintentional change to, or 
noncompliance with, the approved protocol procedures or requirements. Deviations may 
result from the action or inaction of the subject, Investigator, or site staff. All deviations will 
be tracked and should be reported to IRBs in accordance with their reporting policy. 
Examples of deviations include, but are not limited to:  
• Failure to adhere to study exclusion and inclusion criteria.  
• Failure to comply with dispensing or dosing requirements.  
• Use of medications, herbal remedies, supplements, or therapies that are specifically 
prohibited in the protocol.  
• Missed or out-of-window visits.  
• Drug dosing not administered within the time frame specified in the protocol  
• Failure to adhere to test requirements, including vital signs, laboratory tests, physical 
examinations, medical history, etc. – either tests not done, incorrect tests done, or not 
done within the time frame specified in the protocol.  
• Procedural deviations such as incorrect storage of study drug, failure to update the 
PICF when new risks become known, failure to obtain HREC/IRB approvals for the 
protocol and PICF revisions.  
10.9 Efficacy Analysis 
10.9.1 Primary Efficacy Endpoint 
The primary efficacy endpoint is CAPS-5 total symptom severity score at Week 12 and will 
be analyzed with a MMRM with sequential Multiple Imputation (MI) used to estimate the

     Page 55 of 62 
 
missing observations. The repeated measurements will range from Baseline to Week 12 for 
the primary endpoint.  
The primary efficacy model will include the CAPS-5 total symptom severity scores from 
Baseline to Week 12 as the dependent variable, the Baseline CAPS-5 value as a Baseline 
covariate, Week, and treatment group as factors, and treatment group by Week as an 
interaction term. Additional covariates in the model will include gender, age, country 
(Australia/USA), nicotine use at Baseline (Current/Former/Never), and concomitant 
antidepressant use at Baseline (Yes/No).  
Further details of the MMRM and MI for missing values will be included in the SAP prior to 
database lock and subsequent unblinding. 
Each dose group will be compared to placebo. Because this is a Phase II study, the level of 
significance will be 0.05 with no adjustment for multiple comparisons. Additional sensitivity 
analyses will include: 
• MMRM with the ‘as observed’ (i.e. no imputation for missing values) dataset. 
• MMRM with the last observation carried forward (LOCF) dataset. 
• MMRM with the baseline observation carried forward (BOCF) dataset. 
10.9.2 Secondary Efficacy Endpoints 
The effect of each dose of BNC210 on Investigator-rated and self-reported PTSD symptom 
severity, depression, anxiety, cognitive function, global function, quality of life, social 
functioning, and sleep quality after 12 weeks of treatment, will be compared to placebo using 
the following instruments: 
• Cluster score for CAPS-5 Criterion B: Intrusion. 
• Cluster score for CAPS-5 Criterion C: Avoidance. 
• Cluster score for CAPS-5 Criterion D: Negative Alterations in Cognition and Mood. 
• Cluster score for CAPS-5 Criterion E: Arousal and Reactivity. 
• PCL-5. 
• MADRS. 
• HAM-A. 
• CANTAB Cognitive Assessment  
• CGI-S/CGI-I. 
• PGI-S/PGI-I. 
• AQoL-8D. 
• Social functioning: SDS. 
• Sleep monitoring: PSQI. 
The CAPS-5 symptom cluster severity scores, PCL-5, MADRS HAM-A, CANTAB 
Cognitive Assessment, SDS and PSQI, will be analysed as continuous variables using 
MMRM (and MI) as described for the CAPS-5 total symptom severity score. The covariate 
will be the respective baseline continuous variable.  The MMRM analyses for the secondary 
efficacy variables will be repeated using the ‘as observed’ (i.e. no imputation) dataset. For all 
secondary efficacy variables the level of significance will be 0.05 with no adjustment for 
multiple comparisons.

For all variables the data will be graphed over time as adjusted means with 95% confidence 
intervals (CIs). As appropriate the means and 95% CI at Week 12 will be summarized as 
forest plots.  
The CGI-I/CGI-S & PGI-I /PGI-S will be reported as tables of frequencies and percentages.

10.12 Safety Analysis 
10.12.1 Safety Analysis Criteria 
The safety criteria include the following: 
• AEs 
• Vital signs  
• Standard 12-lead ECG 
• Haematology, blood chemistry, urinalysis 
• Physical examination, weight. 
• C-SSRS 
10.12.2 Statistical Methodology 
Analysis of safety parameters will be performed on the Safety Population. 
10.12.3 Columbia Suicide Severity Rating Scale Safety Analysis 
The C-SSRS comprises several categorical questions, which are not summarized into a total 
score. The categorical responses will be summarized by tables of frequencies and percentages 
at Week 15, and over time.  
10.12.4 Adverse Event Analysis  
All AEs will be listed by and summarized by treatment group. 
AEs will be considered as treatment-emergent according to the rule set out in Section 9.7.1. 
Repetitions will only be counted once in summary tables. Repetitions are defined as follows: 
If a given subject presents several AEs with the same verbatim text during the treatment 
period, only one event is defined; the others are considered repetitions or recurring episodes. 
The start time of the event will be the start time of the first occurrence, the end time will be 
the end time of the last episode. The intensity will be the highest recorded intensity for all 
episodes. The causality will be the highest likelihood recorded for all episodes. 
AEs will be summarized by system organ class and preferred term in tables with: 
• The number of subjects with at least one AE and number of AEs for each treatment 
group and overall, 
• Analyses taking into account intensity and drug relationship to treatment could also be 
carried out. 
Other Safety parameters (vital sign measurements, ECG readings, physical examination, and 
laboratory tests) will also be described using descriptive statistics by treatment group when 
applicable, by visit otherwise.  
Description of potentially clinically significant values will be performed for vital signs, ECG 
parameters, blood chemistry and hematology parameters. All these parameters will be listed 
by subject and measurement time. The data outside of normal ranges will be flagged.

The Investigator or the appointed persons agree to complete the subject's eCRF forms after 
each study visit. Only the Investigator or the Investigator designee may enter and correct 
eCRF data.  
Prior to database lock and when authorized by Data Management, the Investigator must sign 
and date the eCRF in order to attest respectively to: 
• authenticity of the data collected in the eCRF, 
• coherence between the data in the eCRF and those in the source documents. 
At the end of the study, the Investigator will keep a .pdf copy of the correctly completed 
eCRFs for his/her own records. The Investigator will keep a log of study volunteers screened 
for study participation and as appropriate, will indicate the reason individual study volunteers 
did not enter the study. The Investigator must submit to the Sponsor or its representatives a 
completed eCRF for each subject who receives any IP. 
The Investigator must guarantee the safety of the study data in the medical files by 
implementing security measures to prevent unauthorized access to the data and to the 
computer system. 
11.2.2 Monitoring 
All aspects of the study will be monitored carefully by the Sponsor’s Designee with respect to 
current GCP and SOPs for compliance with applicable government regulations, the study 
protocol and Investigator’s obligations.  It is the responsibility of the Investigator to provide 
all study records, including eCRFs, source documents, among other records, for review and 
inspection by the Monitor. 
All CRFs will be 100% verified against corresponding source documentation for each subject.  
Monitors will periodically evaluate the progress of the study, including the verification of the 
accuracy and completeness of the eCRFs.  Prior to database lock, the completed eCRFs must 
be reviewed, signed and dated by a qualified physician who is delegated this responsibility by 
the Principal Investigator. 
11.2.3 Audit 
The study may be selected for an audit to inspect the facilities and review the study-related 
records in order to evaluate the trial conduct and compliance with the protocol, ICH, GCP and 
applicable regulatory requirements. 
The Investigator will be informed that an audit will be carried out, at the request of the 
Sponsor, before, during or after the study. 
The Investigator will be informed that the Regulatory Authorities may also carry out an 
inspection. In this case, the Investigator must inform the Sponsor as soon as he/she receives 
the notification of inspection. 
The Investigator must allow the representatives of the Regulatory Authorities and persons 
responsible for the audit to inspect the site, facilities and material used for the study, meet all
