product (IMP) 
LAT8881 (Tyr-hGH177-191), 30 mg capsules and matching placebo. 
Two capsules to be taken at the onset (within one hour from the onset of pain) of a 
migraine headache of moderate to severe intensity. Total daily dose of IMP: 0 or 
60 mg LAT8881 
Indication 
Treatment of acute migraine with or without aura  
Study 
description 
This is a randomised, placebo controlled, double blind, crossover phase IIa proof 
of concept study to investigate the efficacy and safety of oral LAT8881 in acute 
migraine with or without aura. Subjects enrolled in the study will be randomised to 
receive IMP (LAT8881 60 mg or placebo), to be taken at the onset (within one 
hour from the onset of pain) of a migraine headache of moderate to severe 
intensity [Numeric rating scale (NRS) ≥4]. Rescue medication should not be taken 
until at least 2 hours post dose. Subjects will be given a single dose of IMP, to 
treat one migraine headache. 
After treatment of one migraine headache (or a maximum 28 days) the subject will 
return to the clinic for re-evaluation and crossover to the second treatment.  
After treatment of one migraine headache in the second treatment period or a 
maximum of 28 days from commencement of the second treatment period, the 
subject will return to the clinic for re-evaluation.  
An End of study visit (telephone) will occur 7 days after the end of the second 
treatment period.  
Subjects will complete diaries to record menstrual cycle, onset, and nature of 
migraine and non-migraine headaches, pain scores at time of IMP dosing and 
various time points post dose, associated symptoms, episodes of vomiting and 
rescue medication. Adverse events will be monitored.   
Number of 
subjects 
planned 
It is planned to have 20 subjects complete the study, defined as taking one dose of 
IMP in each treatment period and attending the followup (End of study) visit.  
Assuming up to 20% of subjects do not treat one migraine headache in each

treatment period or dropout of the study, 26 subjects will be enrolled in the study.  
If the dropout rate or noncompletion rate is higher than anticipated, additional 
subjects may be enrolled to ensure 20 subjects complete the study. 
Study 
objectives 
Primary 
To evaluate the effect of oral LAT8881 on migraine headache compared with 
placebo, when assessed by the headache severity on an 11 point Numeric Rating 
Scale (NRS) 
Secondary 
1. To evaluate the effect of oral LAT8881 on migraine associated symptoms 
compared with placebo, when assessed by the change in symptoms based on 
a 11 point Likert scale 
2. To investigate the percentage of subjects achieving “no headache pain” 
following treatment with oral LAT8881 for a migraine headache compared with 
placebo at any timepoint to 8 hours post dose, with no use of rescue 
medication 
3. To evaluate the safety and tolerability of single doses of oral LAT8881 in 
subjects with migraine headache 
Exploratory 
1. To investigate the percentage of subjects who are “sustained pain-free,” 
defined as having no headache pain following treatment with oral LAT8881 for 
a migraine headache compared with placebo, with no use of rescue 
medication and no relapse of headache pain within 24 hours (24-hour 
sustained pain-free) after administration 
2. To investigate the time to first pain-free timepoint following treatment with oral 
LAT8881 for a migraine headache compared with placebo to 24 hours post 
dose, with no use of rescue medication  
3. To determine the need for extra analgesic (rescue) medication after treatment 
with oral LAT8881 administration for a migraine headache, compared with 
placebo 
4. To investigate subject satisfaction with treatment of a migraine headache 
5. To investigate other factors influencing the extent of change in pain score and 
symptom scores in subjects with migraine headaches 
Endpoints 
Primary endpoint 
Change in migraine headache pain score, using an 11-point NRS, (0 = none, 10 = 
worst imaginable), from the time of dosing (t = 0 min) to 0.5, 1.0, 1.5, 2, 4, 8 and 
24-hours post dose. Pain is recorded in a subject diary and should reflect the 
subject’s pain at the time of recording. 
Secondary efficacy endpoints 
1. Change in migraine-associated symptoms of nausea, photophobia and 
phonophobia. Symptoms are assessed on an 11- point Likert scale (0 = no 
symptoms, 10 = severe symptoms), at time of dosing and at 0.5, 1.0, 1.5, 2, 4, 
8 and 24 hours post dose. 
2. Change in each subject’s most troublesome symptom that may include 
nausea, photophobia and phonophobia, cognitive impairment, dizziness and

20190725 lat-mig-001 protocol v1.0_redacted.docx Confidential 
page 12 of 59 
functional disability. Symptoms are assessed on an 11- point Likert scale (0 = 
no symptoms, 10 = severe symptoms at time of dosing and at 0.5, 1.0, 1.5, 2, 
4, 8 and 24 hours post dose.  
3. The percentage of subjects achieving “no headache pain” at 0.5, 1.0, 1.5, 2, 4 
and 8 hours post dose. 
Safety endpoints 
1. Changes in physical examinations and vital signs  
2. Changes in clinical laboratory tests  
3. Percentage of treatment emergent adverse events (TEAEs), including serious 
adverse events (SAEs), and suspected unexpected serious adverse reactions 
(SUSARs)  
4. Changes in concomitant medications  
Exploratory endpoints 
1. The percentage of subjects who are “sustained pain-free,” defined as having 
no migraine headache pain at 24 hours, with no use of rescue medication and 
no relapse of headache pain within 24 hours (24-hour sustained pain-free) 
after administration  
2. The time to first pain-free timepoint following treatment with oral LAT8881 
compared with placebo to 24 hours post dose, with no use of rescue 
medication  
3. Supplemental analgesic medication use in the 24 hour post treatment period 
4. Subject satisfaction with each treatment based on a 7-point Likert Scale, 
overall preference for Treatment 1 or Treatment 2, and historical comparison 
with usual treatment  
5. Association between change in headache pain and symptom scores and 
selected subject baseline characteristics, including for example, migraine 
with/without aura, relationship to menstrual cycle.

Study 
procedures 
Screening (Visit 1) 
Potential subjects will be required to provide written informed consent prior to any 
study-specific screening procedures being performed. A unique Screening number 
(Subject ID) will be assigned. During the screening procedure, subjects will 
undergo screening assessments including medical history, height, weight, 12-lead 
ECG, vital signs, and full physical examination. In addition to eligibility criteria, 
medical history will include details of history of migraine headaches: average 
duration (shortest and longest), description of nature (throbbing, aggravating 
factors, unilateral/bilateral, aura), severity and associated symptoms including 
most troublesome symptom and relationship to menstrual cycle. 
Concomitant medications will be recorded. Blood will be collected for routine 
haematology and biochemistry screening and, in female subjects of child-bearing 
potential, to test for pregnancy. A urine sample will be collected for urinalysis.  
Subjects deemed likely to be eligible for the trial will be given two diaries after 
completion of the above screening tests. The headache diary will be used to 
record menstrual cycles, and onset and nature of headaches (both migraine and 
non-migraine). In addition, they will be instructed to complete a migraine diary 
during a migraine headache to collect pain and symptom scores and concomitant 
medications. Scores will be recorded before taking their usual migraine medication 
and at 0.5, 1.0, 1.5, 2, 4, 8 and 24 hours after taking their usual migraine 
medication. The screening diaries will be completed for a minimum of 28 days. If 
the subject does not experience a migraine headache in this period or menstrual 
bleeding (menstruating females only), the screening diary period may be extended 
up to 35 days. 
Note that diary entries completed prior to Day 1 will be used only to confirm 
compliance with diary completion requirements on the day of a migraine, to verify 
the nature of migraine headache and the subject’s most troublesome symptom.  
Visit 2 
Treatment period 1  
Subjects will return to the unit on Day 1 (Visit 2) with their diaries completed from 
Day -28 to Day -1 inclusive. If a subject has not experienced a migraine headache 
or menstrual bleeding (menstruating females only) during the 28-day period, the 
screening diary period may be extended by 7 days.  
On Day 1, assessments including 12-lead ECG, vital signs, a targeted physical 
examination, recording of concomitant medications, review of the subject’s diaries, 
blood and urine sampling for safety monitoring, and urine sampling for pregnancy

testing in FOCBP, will be conducted. Results from safety monitoring tests are not 
required prior to randomisation.  
Eligibility will be confirmed and subjects will be randomised to LAT8881 60 mg or 
placebo.  
Subjects will leave the unit with their two diaries, and one dose of IMP and 
instructions to take the dose within one hour of the onset of a migraine headache 
of moderate to severe intensity (NRS ≥4). The headache diary will be used to 
record menstrual cycles and onset and nature of headaches (both migraine and 
non-migraine). The migraine diary will be used during a migraine headache to 
collect pain and symptom scores and concomitant medications before taking the 
IMP and at 0.5, 1.0, 1.5, 2, 4, 8 and 24 hours after taking the dose. No analgesics 
or antimigraine medication other than medications for routine prophylaxis not on 
the Prohibited medicines list may be taken within 24 hours prior to taking the dose 
of IMP. Rescue medication is permitted a minimum of 2 hours post IMP dose. The 
subject’s symptoms including nausea, photophobia and phonophobia plus the 
subject’s most troublesome symptom if other than nausea, photophobia or 
phonophobia will be recorded at the time of dosing and at 0.5, 1.0, 1.5, 2, 4, 8 and 
24 hours after taking the dose. Episodes of vomiting will also be recorded. 
The subject will be instructed to phone the clinic within one business day of taking 
the dose. 
On Day 15, if the subject has not phoned the clinic, the subject will be phoned to 
remind them to complete their diaries and to phone the clinic when the dose has 
been taken.  
Subjects will return to the clinic for Visit 3 within 5 business days after taking the 
dose or a maximum of 28 days after Visit 2 if IMP has not been taken. 
Visit 3 
Assessments including 12-lead ECG, vital signs, a targeted physical examination 
and concomitant medications will be recorded and the subject’s diaries will be 
reviewed. Blood and urine samples will be taken for safety monitoring and urine for 
pregnancy test (FOCBP only). Subject satisfaction with Treatment period 1 IMP 
will be recorded. Results from safety monitoring tests are not required prior to 
dosing. 
Treatment period 2 
Subjects will leave the clinic with their diaries and one dose of IMP (alternate 
treatment), instructions to take the dose within one hour of the onset of a migraine 
headache of moderate to severe intensity (NRS ≥4),  but not less than 48 hours 
after last dose and instructions to complete the diaries as for Treatment period 1. 
No analgesics or antimigraine medication other than medications for routine 
prophylaxis not on the Prohibited medicines list may be taken within 24 hours prior 
to taking the dose of IMP. Rescue medication is permitted a minimum of 2 hours 
post dose. 
The subject will be instructed to phone the clinic within one business day of taking 
the dose. 
If the subject has not phoned the clinic, the subject will be phoned 14 days after 
Visit 3 to remind them to complete their diaries and to phone the clinic when the

Subjects will return to the clinic for Visit 4 within 5 business days, after taking the 
dose or a maximum of 28 days after Visit 3 if IMP has not been taken. 
Visit 4 
Subjects will return to the clinic with their diaries at completion of Treatment 
period 2.  
Blood and urine samples will be taken for safety analysis. 12-lead ECG, vital signs, 
concomitant medications, targeted physical examination results and adverse 
events will be recorded. Subjects will be asked to complete assessments for 
Subject satisfaction of IMP Treatment period 2 and overall preference.   
End of study, Visit 5 
Subjects will be phoned 7 days after Visit 4 to review any new or changed adverse 
events or changes in concomitant medications.  
Early withdrawal 
An early withdrawal visit should be conducted within 7 days of the subject 
withdrawal, and/or a minimum 48 hours after last dose of IMP. 
Subjects who are completing an early withdrawal visit will return with their diaries 
and IMP.  
Blood and urine samples will be taken for safety analysis. 12-lead ECG, vital signs, 
concomitant medications, targeted physical examination results and adverse 
events will be recorded. Subjects will be asked to complete assessments for 
Subject satisfaction.   
Statistical 
analysis 
No formal statistical sample size estimation has been performed due to the 
exploratory nature of this study. Rather the sample size is based on clinical and 
practical considerations. 
The safety population includes all subjects who receive at least one dose of IMP 
and will be the population used for the analysis of safety endpoints. The full 
analysis set (FAS) population will be used to present demographic and other 
baseline characteristics and summaries of efficacy endpoints. A per-protocol (PP) 
population will be used as the primary population for efficacy analyses and to 
analyse exploratory endpoints. The PP population will be based on IMP exposure, 
including the time of any episodes of vomiting and major protocol deviations.  
The descriptive summaries for the categorical variables will include counts and 
percentages. The descriptive summaries for the continuous variables will include 
number of subjects (n), means, medians, standard deviations, and minimum and 
maximum values. All data will be listed for all subjects. As this is a Phase IIa proof 
of concept study, no formal statistical hypotheses are being specified although 
some may be investigated as part of the data presentation. A p-value of <0.05 will 
be declared statistically significant. Treatment period order will be ignored in any 
treatment comparisons. Results will be presented in a descriptive format by 
treatment within each treatment period and overall. Treatment comparisons will 
take into account the paired nature of the treatment responses where feasible.  
Individual pain score-time profiles for each treatment within each subject will be 
presented graphically. The difference between the NRS pain scores at each 

Protocol number LAT-MIG-001 
Lateral Pharma Pty Ltd 
 
20190725 lat-mig-001 protocol v1.0_redacted.docx Confidential 
page 18 of 59 
timepoint for LAT8881 60 mg compared with placebo within each subject will be 
estimated and presented graphically. The number of subjects, mean, standard 
deviation, minimum and maximum NRS pain score at each timepoint, change from 
baseline, difference between treatments at each timepoint and change from 
baseline difference between treatments will be presented for each treatment 
overall and within each treatment period. 
Nausea, photophobia and phonophobia symptom scores will be summarised and 
presented in the same way as the pain scores. The number and percent of 
headaches with each most troublesome symptom of migraine including nausea, 
cognitive impairment, dizziness, functional disability, photophobia phonophobia 
and vomiting will be summarised for each treatment. The most troublesome 
symptom scores will be summarised and presented in the same way as the pain 
scores.  
The number and percent of subjects with 'no headache pain' at each time point will 
be presented for each treatment. Two-way tables will present the 
presence/absence of pain classified for each treatment at each timepoint. Absence 
of pain will be defined as a pain NRS score of 0 or 1. 
The number and percent of subjects who are “sustained pain-free” at 24 hours 
after dose of IMP will be presented by treatment. A two-way table will present the 
“sustained pain-free” status for subjects on each treatment.  
The number and percent of subjects will be summarised by their first pain-free 
timepoint. A two-way table will present the classification of each subject’s first 
pain-free timepoint by treatment. Kaplan-Meier curves will present the time to first 
pain-free timepoint.  
Patient Satisfaction for each treatment recorded on a 7-point Likert scale and the 
within-subject difference between treatments will be summarised. The mean 
difference between treatments will be compared with a paired t-test and the 95% 
confidence interval for the mean difference will be presented. The number and 
percent of subjects from the overall satisfaction score will be presented for each 
treatment.    
Additional exploratory analyses to investigate the association between change in 
headache pain and symptom scores and selected subject baseline characteristics 
will be undertaken in a similar fashion with descriptive statistics. 
Adverse event data will be coded to system organ class and preferred term using 
the Medical Dictionary for Regulatory Activities (MedDRA). A by-subject AE data 
listing, including verbatim term, preferred term, system organ class, severity and 
relationship to investigational product will be provided. The number and 
percentage of subjects experiencing any treatment-emergent AE and the number 
of individual adverse events, overall, and by system organ class and preferred 
term will be tabulated. Treatment emergent adverse events will also be 
summarised by severity and relationship to investigational product.  
Absolute values and changes from baseline in vital signs, haematology and clinical 
chemistry parameters will be tabulated at each visit. 
Prior and concomitant medications will be listed by subject and coded using the 
most current World Health Organisation (WHO) drug dictionary and summarised 
by WHO Drug Class and preferred term for each treatment period and treatment

3. Introduction and background information 
3.1 
Acute migraine 
Migraine is a disabling neurovascular disorder, characterised by moderate to severe headaches which 
are usually throbbing, affect one side of the head and are accompanied by nausea and sensitivity to light 
and/or sound. It is one of the most common chronic conditions worldwide.  
The most common migraine types are migraine without aura (common migraine) and migraine with aura 
(classic migraine).3 
Migraine without aura is identified by headache symptoms lasting 4–72 hours, commonly with a unilateral 
location, pulsating quality of moderate or severe intensity, aggravated by routine physical activity and 
associated with nausea and/or light and sound sensitivity. Diagnosis is based on at least five attacks.3  
Migraine with aura is identified by recurrent attacks, lasting minutes, of unilateral fully reversible visual, 
sensory or other central nervous system symptoms that usually develop gradually and are commonly 
followed by headache and associated migraine symptoms. Diagnosis of migraine with aura requires at 
least two such attacks.3 
Recognition of the pathophysiology of migraine has evolved from the belief that it was a primary 
consequence of intracranial vasodilation, to the more recent theory that it is initiated by a complex series 
of neural and vascular events.4 According to this theory, migraine is primarily a neurogenic process with 
secondary changes in cerebral perfusion. The headache pain itself is considered to be due to activation 
of the trigeminovascular pathway, but it has been suggested that there are multiple neuronal functional 
abnormalities which are involved in the initiation of a migraine.5 
Migraine prevalence is reported to be between 2.6% and 21.7%, with an average of approximately 12%.6 
In the 2016 Global Burden of Disease Study,7 migraine (including medication overuse headache) ranked 
in the top ten of years lived with disability in all 195 countries and territories investigated, and overall was 
the second largest cause of disability. 
In the years prior to puberty, migraine is more common among boys than girls. However, by the onset of 
puberty, migraine is more prevalent in girls. Females in their late teens are about twice as likely to suffer 
from migraine as males of the same age.8 The prevalence of migraine peaks in both sexes and is at its 
highest from ages 25 to 55 years, when there is a substantial loss of productivity because of work 
absences and reduced efficiency. In Australia, it is estimated that the total economic cost from migraine 
in 2018 was $35.7 billion, consisting of $14.3 billion of health system costs, $16.3 billion of productivity 
costs, and $5.1 billion of other costs.9 There are also additional significant wellbeing costs for these 
individuals and their families.  
Selecting the optimal treatment for a particular patient is challenging because the severity, frequency, 
and characteristics of migraine can vary between individuals or even within the same individual over time. 
Treatment plans are usually individualised and based on a number of factors, such as patient preference, 
the severity and frequency of attacks, co-morbidities and concomitant medications.  
The American Headache Society guidance for the treatment of acute migraine10 is to use non-steroidal 
anti-inflammatory drugs (NSAIDs), including aspirin, non-opioid analgesics, paracetamol, or caffeinated 
analgesic combinations (eg aspirin + paracetamol + caffeine) for mild-to-moderate attacks. For moderate 
or severe attacks and mild-to-moderate attacks that respond poorly to NSAIDs or caffeinated 
combinations, migraine-specific agents (triptans, dihydroergotamine) are suggested.  
For some patients, acute treatments are not sufficiently effective or are not well tolerated and 
preventative medication may be suggested. However, non-compliance with chronic medication or side 
effects from treatment may reduce the effectiveness of such interventions. The availability of an effective 

Protocol Number LAT-MIG-001 
Lateral Pharma Pty Ltd 
 
20190725 lat-mig-001 protocol v1.0_redacted.docx Confidential 
page 22 of 59 
acute therapy, with a novel mechanism of action and good tolerability, will improve the options for 
patients with acute migraine who do not wish to progress to chronic preventative therapies.  
Some of the clinical features of migraine, such as allodynia and hyperalgesia, resemble the symptoms of 
neuropathic pain, leading to the suggestion that migraine might be a neuropathic pain disorder.11 It is in 
this context that it has been suggested that LAT8881, with its demonstrated activity in preclinical 
neuropathic pain models and evidence of inhibition of neuronal excitability (Section 3.2.1.1), might be a 
useful therapeutic agent for migraine. 
This is the first clinical study with LAT8881 in migraine and will assess its potential for treating acute 
migraine in a proof of concept trial. 
3.2 
LAT8881 
LAT8881 is a 16 amino acid peptide fragment based on human-growth hormone (hGH). It consists of the 
15 amino acids from the C-terminus of human growth hormone, to which a terminal tyrosine is added at 
the N-terminal end (Tyr-hGH177-191). Its molecular formula is NH2-Tyr-Leu-Arg-Ile-Val-Gln-Cys-Arg-Ser-
Val-Glu-Gly-Ser-Cys-Gly-Phe-OH, with a disulphide bridge between amino acids 7 and 14 (Figure 1). 
 
Figure 1: LAT8881 amino acid sequence 
LAT8881 was initially developed for the treatment of obesity (known during these studies as AOD9604). 
Six clinical trials involving 936 subjects were completed, with over 700 subjects treated with oral LAT8881 
(Section 3.2.2). There were no significant safety issues but the most recent efficacy study (METAOD006) 
did not meet the primary endpoint and development was discontinued for this indication in 2007. 
A clinical study is currently in progress to evaluate the efficacy and safety of LAT8881 in neuropathic 
pain. This study is being conducted at four Australian and two UK sites, and is planned to recruit up to 55 
subjects, so that 44 subjects complete the study.  
3.2.1 Non-clinical studies 
3.2.1.1 Non-clinical models  
As there are no established specific pharmacological models of migraine,12 non-clinical studies 
supporting a role for LAT8881 in migraine are based on its activity in relieving neuropathic pain as this 
action has been suggested to be relevant to its potential role in migraine.11 These studies are 
summarised in Table 1. Further details are provided in the Investigator’s Brochure.

3.2.1.2 Mechanism of action 
LAT8881 induced a membrane potential hyperpolarisation and inhibition of neuronal excitability when 
incubated with spinal cord slices taken from rats with confirmed neuropathic symptoms ((Study PDS003b, 
Figure 2). This is considered to be relevant to its potential therapeutic activity in migraine. 
 
Figure 2: Continuous recording of the effect of LAT8881 on membrane potential  
Mean resting membrane potential was reduced from -49.3 ± 2.4 mV (mean ± SEM) to a new steady state 
resting potential of -63 ± 2.4 mV in the presence of 10 µM LAT8881. When normalised to control resting 
potential, the LAT8881-induced inhibition amounted to a 30.6 ± 11.1% (P=0.033) change in membrane 
potential. 
Membrane potential hyperpolarisation was consistently associated with a significant reduction in neuronal 
input resistance with LAT8881, from a mean control resting value of 579.6 ± 178.9 MOhm to 301.0 ± 
103.2 MOhm (P=0.012) in the presence of LAT8881, amounting to a 278.6 ± 77.8 MOhm reduction in 
neuronal input resistance. When normalised relative to control, LAT8881-induced inhibition was 
associated with a reduction in input resistance to 49.4 + 4.4 % of control (P=0.00003). 
3.2.1.3 Non-clinical safety studies 
Studies in rats and monkeys at doses up to 10 mg/kg LAT8881 administered intravenously for up to 
periods of 28 days had no clinically significant toxic effect in either species. Fourteen-day treatment with 
oral doses of LAT8881 up to 100 mg/kg/day was well tolerated in both rats and monkeys and without any 
overt systemic toxicity. 
Chronic toxicity testing was conducted in both rodent and non-rodent species. Doses of 0 (control), 0.5, 
20 and 100 mg/kg/day LAT8881 (0, 3.5, 140, 700 mg/m2/day) were administered orally to rats once per 
day for six months (26 weeks). There were no unscheduled deaths and no treatment-related clinical 
signs. No marked effects on body weight were observed and there were no treatment-related effects on 
food consumption, food conversion efficiency ratios, ophthalmic examination, organ weights, 
macropathology, histopathology or clinical laboratory parameters. There was no effect of LAT8881 on 
bone densitometry.   
LAT8881 0.5, 10 and 50 mg/kg/day (6, 120 and 600 mg/m2/day) or vehicle control was administered to 
cynomolgus monkeys once per day for nine months. In this study there were no unscheduled deaths and 
no clinical signs attributable to treatment with LAT8881. There were no treatment-related changes in 
body weight, ophthalmology, haematology, biochemistry, urinalysis, organ weights, necropsy or histology. 
There was no effect of LAT8881 on bone densitometry.

page 25 of 59 
No antibodies to LAT8881 were detected in the serum of rats and monkeys at the end of the toxicological 
studies, indicating that LAT8881 was not neutralised by an antibody reaction, and thus LAT8881 is 
considered unlikely to be immunogenic.   
Extensive genotoxicity testing has been conducted. It is considered unlikely that LAT8881 is a potential 
genotoxic hazard to humans. 
Reproductive studies have been undertaken in rats and rabbits at doses up to 50 mg/kg/day (rabbit) and 
100 mg/kg/day (rat). The rabbit studies found no evidence of an effect on foetal development when 
administered from Days 6-18 of gestation. The rat studies involved dosing from 2 weeks pre-mating 
(males and females) up to Day 6 of lactation (females) or 2 weeks after pup delivery (males). No effect on 
reproduction was observed in these studies.  
More detailed results from the preclinical studies with LAT8881 are provided in the Investigator’s 
Brochure. 
3.2.2 Clinical studies 
Six clinical studies with LAT8881 have been completed, with over 700 subjects treated with LAT8881 
(Table 2Table 2: Summary of clinical studies with LAT8881). These studies were designed to investigate 
the safety and tolerability of LAT8881 and subsequently its efficacy in the treatment of obesity 
(METAOD005, METAOD006).  
A seventh study (LAT-NP-001) to investigate the safety and efficacy of LAT8881 in neuropathic pain at a 
dose of 60 mg per day (30 mg twice daily) has recently commenced and is recruiting subjects. No results 
from this study are yet available.

In all development studies for obesity, it was noted that the study drug was well tolerated. The only dose-
related adverse event (AE) trend was an increased incidence of gastrointestinal effects and general body 
symptoms of abdominal pain and headache in Study METAOD004 at 54 mg. This trend was not 
observed in subsequent studies.

5. Study design 
5.1 
Overall study design 
This is a randomised, placebo-controlled, double-blind, crossover, Phase IIa study to investigate the 
efficacy and safety of oral LAT8881 in acute migraine headache with or without aura. The overall study 
design is shown in  
 
Figure 3. Details of the procedures during each phase are described in Section 9. 
 
 
 
 
 
 
 
Figure 3: Overall study design for LAT-MIG-001 
Subjects entered into the study will be randomised to receive IMP (LAT8881 60 mg or placebo), to be 
taken at the onset (within one hour from the onset of pain) of a migraine headache of moderate to severe 
intensity. Rescue medication should not be taken until at least 2 hours post dose. Subjects will be given 
one dose of IMP (2 capsules), to treat one migraine headache. 
After treatment of one migraine headache (or a maximum 28 days) the subject will return to the clinic for 
re-evaluation and crossover to the second treatment. In the second treatment period, they will take IMP in 
the same manner as in treatment period 1. 
A followup (End of study) visit will occur within 7 days after treatment of one migraine headache in the 
second treatment period or a maximum 8 weeks from randomisation. 
Subjects will complete diaries to record menstrual cycle (in menstruating females), onset and nature  of 
migraine and non-migraine headaches, pain scores at time of IMP dosing and various time points post 
dose, associated symptoms and rescue medication. Adverse events will be monitored.   
5.2 
Justification of study design 
The design of this Phase IIa proof of concept trial as a randomised, double blind, placebo controlled, 
crossover study has, in general, followed clinical trial guidelines developed by the International Headache 
Society.13  
The crossover design was chosen to increase efficiency. As each subject acts as his/her own control the 
trial requires a smaller number of subjects than for a parallel group design. The crossover design also 
allows subject treatment preferences to be assessed.  
Period and carryover effects are potential disadvantages of a crossover trial design, but these 
considerations are considered unlikely to impact significantly on this study. As eligible subjects are 
required to have a stable pattern of migraine history, 2–8 attacks per month for the previous 12 months, 
and LAT8881 is a single dose, symptomatic treatment, no period effect is anticipated. Available 
preclinical pharmacodynamic data does not suggest that a single dose of LAT8881 would have a 
carryover effect, and a washout period of at least 48 hours between dosing is considered adequate. 
Preclinical and clinical safety data have not shown any significant adverse effects with LAT8881 that

would affect a subsequent treatment period, nor are there any notable AEs that would enable subjects to 
discriminate between active and placebo treatments.  
5.3 
Justification of dose 
The dose of 60 mg is based on preclinical studies in neuropathic pain models and preclinical and clinical 
safety data with LAT8881. In a number of models of neuropathic pain, LAT8881 significantly increased 
paw withdrawal time to a painful stimulus (a measure of analgesia) at dose of 5 mg/kg. This dose 
approximates to a dose of 0.8 mg/kg in man, based on normalisation to body surface area.14 Given that 
LAT8881 has a good clinical safety profile at doses up to 54 mg/day, refer study METAOD004, and that a 
dose of 60 mg (30 mg twice per day) is currently being evaluated in a study in neuropathic pain, it was 
determined that a 60 mg dose would be an appropriate dose for initial evaluation of LAT8881 in migraine 
headache.  
Full details of these preclinical and clinical studies are available in the Investigator’s Brochure. 
Following this study, it is planned to investigate the dose response to LAT8881 in patients with migraine 
headaches and to determine a minimum effective and optimal therapeutic dose. 
5.4 
Number of planned subjects  
It is planned to have 20 subjects complete the study, defined as taking one dose of IMP in each treatment 
period and attending the followup (End of study) visit.  
Assuming up to 20% of subjects do not treat one migraine headache in each treatment period or dropout 
of the study, 26 subjects will be enrolled in the study.  
If the dropout rate or non-completion rate is higher than anticipated, additional subjects may be enrolled 
to ensure 20 subjects complete the study. 
5.5 
Duration of study 
Approximately 9 months 
5.6 
Duration of subject participation  
Maximum participation duration is 14 weeks (98 days): Screening (28-35 days), Treatment period 1 (28 
days), Treatment period 2 (28 days), followup (7 days). 
5.7 
Withdrawal of subjects from study 
Subjects can terminate their participation in the study at any time, without giving a reason and without 
prejudice to further treatment. Subjects may also be withdrawn at any time at the discretion of the 
investigator(s) or sponsor for safety, behavioral or administrative reasons.   
Subjects who discontinue from the study should always be asked about the reason(s) for their 
discontinuation and about the presence of any adverse events. The reason(s) for withdrawal will be 
documented in the case report form (CRF). 
Possible reasons for discontinuation of a subject may include: 
• 
Withdrawal of consent by the subject 
• 
Serious or significant AE or laboratory abnormality 
• 
Non-compliance with the protocol  
• 
The need to take medication which may interfere with study measurements or is contraindicated 
• 
New inter-current diseases, which may affect the safety of the IMP  

Protocol Number LAT-MIG-001

page 30 of 59 
• 
Subject is lost to followup  
• 
Withdrawal for other reasons 
• 
Lateral terminating the study for administrative, financial, or other reasons    
Subjects withdrawing from the study will be requested to attend an End of study Visit. If the subject 
withdraws during the treatment period, the subject should attend the End of study visit within one week of 
the subject withdrawal, and/or a minimum 48 hours after last dose of IMP. 
Any new AEs occurring during that period must also be reported in the CRF and must be followed up until 
resolved, unless, in the investigator’s opinion, the condition is unlikely to resolve. This visit is primarily for 
the purposes of monitoring subject safety. 
Any AEs that are continuing at the time of withdrawal from the study, should, wherever possible, be 
followed to resolution or stabilisation, whichever is earlier. 
Reasonable efforts will be made to contact subjects who are lost to followup. These must be documented 
in the subject’s source documents.  
5.8 
Replacement of subjects 
Subjects who withdraw after randomisation will not be replaced.

7.1 
Description 
The IMP is supplied as opaque, size 0 capsules, in a high-density polyethylene bottle containing 2 
capsules. One bottle will contain sufficient capsules for the treatment of one migraine headache in one 
treatment period. 
7.2 
Formulation 
7.2.1 LAT8881 capsules 
Each capsule contains 30 mg LAT8881 plus L-arginine, polyethylene glycol and mannitol as excipients. 
7.2.2 Placebo capsules 
Placebo capsules contain the excipients L-arginine, polyethylene glycol and mannitol only (without 
LAT8881).  
7.3 
Manufacturer 
LAT8881 is is manufactured by Polypeptide Group Torrance, California, USA in accordance with current 
Good Manufacturing Practice (cGMP).  
The active and placebo blends for encapsulation is formulated and the capsules are filled by PCI Pharma 
Services (PCI), Port Melbourne, Victoria, Australia under cGMP conditions. 
PCI Pharma is responsible for quality control and stability testing. 
7.4 
Storage 
At the study site, the IMP must be stored refrigerated (2-80C) in a secure area, with access limited to 
authorised personnel.  
Subjects will also be asked to store their treatment at home under refrigeration. 
7.5 
Packaging and labelling 
IMP capsules will be packaged in bottles by PCI. Each bottle will contain 2 IMP capsules (2 capsules of 
formulated LAT8881 or 2 placebo capsules). The two bottles for treatment of each subject 
(active/placebo) will be packaged together in a clear plastic bag, according to the randomisation schedule 
prepared by the unblinded study statistician. Each bottle will appear identical to the other bottle in the 
box, except for the treatment period number (1/2 or 2/2) on the label. 
Bottles containing the IMP capsules and the bag in which they are packed will be labelled according to 
Annex 13 of the PIC/S Guide to Good Manufacturing Practice.15  
Each bottle will have both a permanently attached label and a tear-off drug accountability label. The tear-
off accountability label must be removed and attached to the Drug Accountability log when the product is 
dispensed. On dispensing, a dispensing label will be attached permanently to the bottle.  
Details of labelling and dispensing will be provided in the Study procedures manual. 
7.6 
Randomisation and blinding 
A computer-generated randomisation schedule and treatment allocation will be prepared by an unblinded 
statistician prior to the start of the study.  

Protocol Number LAT-MIG-001 
Lateral Pharma Pty Ltd 
 
20190725 lat-mig-001 protocol v1.0_redacted.docx Confidential 
page 35 of 59 
The treatment sequence each subject will receive will not be disclosed to the investigator, study site 
personnel, subjects, or sponsor personnel. The randomisation codes will be available to the Investigator if 
required for emergency unblinding purposes (see Section 8.1). 
7.7 
Dispensing of investigational product  
The investigator is responsible for ensuring that IMP is dispensed in accordance with the protocol and 
only to subjects enrolled in the study.  
On the morning of Day 1, after receipt of a prescription/authorisation from the investigator (or delegate), 
the study nurse (or Investigator) will obtain the allocated treatment. The subject’s study number, date and 
treatment number will be recorded in the Drug accountability log. The log will be countersigned by the 
investigator and must be available for inspection at any time. 
7.8 
Method for assigning subject study number  
At screening, each subject will, in chronological order, be allocated a unique Screening number (Subject 
ID). 
At randomisation on Day 1, the subject will be assigned a unique Randomisation number, which will be 
allocated in ascending order according to their chronological order of inclusion in the study. Confirmation 
of the randomisation number allocated to each subject will be documented in the drug accountability 
records and recorded in the CRF.  
The Subject ID number will be used to identify the subject throughout the study and on all study-related 
documentation. 
7.9 
Accountability of study supplies 
All supplies of IMP are provided for use only in this clinical study and must not be used for any other 
purpose. 
The investigator or designee is responsible for accountability of IMP, reconciliation and record 
maintenance. The investigator or designated site staff must maintain accountability records throughout 
the course of the study including prescriptions for IMP, records of the amount of IMP dispensed, the 
identification of the subject to whom the IMP was dispensed, the date and the amount dispensed. 
Subjects must bring their medication bottles with them to clinic visits at the end of each treatment period 
and the number of remaining capsules will be entered onto the CRF. The product, including used bottles 
and records, must be available for inspection by a study monitor during the study.  
Following completion of the study, remaining unused supplies will be returned to Lateral or destroyed as 
directed by the sponsor. 
7.10 Doses and treatment regimens 
Subjects will be instructed to take one dose of IMP (two capsules) with water within one hour of the onset 
of a migraine headache of moderate to severe intensity.  
7.11 Dose reduction/dose adjustments 
No within-subject dose reductions or adjustments are permitted. If a subject experiences an adverse 
event requiring (in the investigator’s opinion) temporary or permanent suspension of the IMP, the subject 
should be withdrawn from the study (refer to Section 5.7).

8. Treatment compliance 
Subjects will be asked to return their IMP bottles for a capsule count at each end of treatment period visit. 
Study drug accountability forms will be kept by pharmacy during the study and will be reviewed by the 
study monitor. Treatment compliance will be recorded in the subject’s source documents and the CRF.  
8.1 
Unblinding 
8.1.1 Medical emergency 
In a medical emergency, when management of a subject’s condition requires knowledge of the study 
drug, the code may be broken to determine the treatment allocation of the subject. Details will be 
provided in the Study manual. 
Wherever possible, such emergencies should be discussed with the study medical monitor and/or 
sponsor before breaking the code and disclosure of the treatment allocation (or as soon as possible 
thereafter). The date, reason for and name of the individual breaking the code will be documented along

9. Study procedures 
The Schedule of Assessments for the study are provided in Section 2. 
9.1 
Subject informed consent 
Following identification of potential subjects, staff in the clinic will contact the subject, explain the nature 
of the study and confirm potential interest and eligibility. The Participant (Subject) information sheet (PIS) 
and Consent forms (ICFs) may be provided. The subject will then be invited to attend the clinic for further 
information, signing of the ICF and conduct of screening procedures. 
The investigator must provide adequate information regarding the study, including its purpose, possible 
risks and potential benefits. Subjects must also be advised that they are free to discontinue from the 
study at any time. Subjects must be given time to review the study information and ask any questions. 
Written informed consent must be provided by the subject before any tests or investigations outlined in 
the study protocol are carried out. 
The ICF must be personally signed and dated by both the investigator and the subject. The investigator 
must store the original, signed ICF with the subject’s medical notes/source documents. A copy of the 
signed and dated ICF will be given to the subject.  
Screening procedures may commence immediately following signing of the ICF.  
9.2 
Screening visit (Visit 1) 
After written informed consent has been obtained, a unique Screening Number (Subject ID) will be 
assigned and screening assessments may commence.  
During the screening procedure, Days -28 to Day – 1 inclusive, subjects will undergo screening 
assessments including medical history, height, weight, 12-lead ECG, vital signs, and full physical 
examination. In addition to eligibility criteria, medical history will include details of history of migraine 
headaches, average duration (shortest and longest), description of nature (throbbing, aggravating factors, 
unilateral/bilateral, aura), severity and associated symptoms including most troublesome symptom and 
relationship to menstrual cycle (menstruating females). 
Concomitant medications will be recorded. Blood will be collected for routine haematology and 
biochemistry screening and, in female subjects of child-bearing potential, to test for pregnancy. A urine 
sample will be collected for urinalysis.  
Subjects deemed likely to be eligible for the trial will be given two diaries after completion of the above 
screening tests, shown how to record and to list concomitant medications. The headache diary will be 
used to record menstrual cycles, and onset and nature of headaches (both migraine and non-migraine). 
In addition, they will be instructed to complete a migraine diary during a migraine headache to collect pain 
and symptom scores and concomitant medications. Scores will be recorded before taking their usual 
migraine medication and at 0.5, 1.0, 1.5, 2, 4, 8 and 24 hours after taking their usual migraine medication.  
The screening diaries will be completed for a minimum of 28 days. If the subject does not experience a 
migraine headache in this period or menstrual bleeding (menstruating females only), the screening diary 
period may be extended by 7 days, ie up to 35 days total. 
Note that diary entries completed prior to Day 1 will be used only to confirm compliance with diary 
completion requirements on the day of a migraine headache, to verify the nature of migraine headache 
and the subject’s most troublesome symptom.

9.3 
First treatment period (Visit 2) 
Subjects will return to the unit on Day 1 (Visit 2) with their diaries completed from Day -28 to Day -1 
inclusive. If a subject has not experienced a migraine headache or menstrual bleeding (menstruating 
females only) during the 28-day period, the screening diary period may be extended to 35 days.  
On Day 1, assessments including 12-lead ECG, vital signs, a targeted physical examination, recording of 
concomitant medications, review of the subject’s diaries, blood and urine sampling for safety monitoring, 
and urine sampling for pregnancy testing in FOCBP, will be conducted. Results from safety monitoring 
tests are not required prior to randomisation.  
Eligibility will be confirmed and subjects will be randomised to LAT8881 60 mg or placebo.  
Subjects will leave the unit with their two diaries, and one dose of IMP and instructions to take the dose 
within one hour of the onset of a migraine headache of moderate to severe intensity (NRS ≥4). The 
headache diary will be used to record menstrual cycles and onset and nature of headaches (both 
migraine and non-migraine). The migraine diary will be used during a migraine headache to collect pain 
and symptom scores and concomitant medications before taking the IMP and at 0.5, 1.0, 1.5, 2, 4, 8 and 
24 hours after taking the dose. No analgesics or antimigraine medication other than medications for 
routine prophylaxis not on the Prohibited medicines list may be taken within 24 hours prior to taking the 
dose of IMP. Rescue medication is permitted a minimum of 2 hours post dose. The subject’s symptoms 
including nausea, photophobia and phonophobia plus the subject’s most troublesome symptom if other 
than nausea, photophobia or phonophobia will be recorded immediately before dosing and at 0.5, 1.0, 
1.5, 2, 4, 8 and 24 hours after taking the dose. Episodes of vomiting will also be recorded. 
The subject will be instructed to phone the clinic within 24 hours (or one business day) of taking the dose. 
On Day 15, if the subject has not phoned the clinic, the subject will be phoned to remind them to 
complete their diaries, and to phone the clinic when the dose has been taken.  
Subjects will return to the clinic for Visit 3 within 5 business days after taking the dose or a maximum of 
28 days after Visit 2. Subjects should be reminded to bring their diaries and medication container to the 
visit.  
9.4 
Visit 3 
Assessments including 12-lead ECG vital signs, a targeted physical examination and concomitant 
medications will be recorded and the subject’s diaries will be reviewed. Blood and urine samples will be 
taken for safety monitoring and pregnancy testing (FOCBP). Subject satisfaction with Treatment Period 1 
IMP will be recorded (if dose taken). Results from safety monitoring tests are not required prior to dosing. 
Treatment period 2 
Subjects will leave the clinic with their diaries and one dose of IMP (alternate treatment), to take the dose 
within one hour of the onset of a migraine of moderate to severe intensity (NRS ≥ 4), but not less than 48 
hours after last dose, and instructions to complete the diaries as for Treatment period 1. No analgesics or 
antimigraine medication other than medications for routine prophylaxis not on the Prohibited medicines 
list may be taken within 24 hours prior to taking the dose of IMP. Rescue medication is permitted a 
minimum of 2 hours post dose. 
The subject’s symptoms including, nausea, photophobia and phonophobia plus the subject’s most 
troublesome symptom if other than nausea, photophobia or phonophobia will be recorded at the time of 
dosing and at 0.5, 1.0, 1.5, 2, 4, 8 and 24 hours after taking the dose. Episodes of vomiting will also be 
recorded 
The subject will be instructed to phone the clinic within 24 hours (or one business day) of taking the 
second dose.

If the subject has not phoned the clinic, the subject will be phoned 14 days after Visit 3 to remind them to 
complete their diaries, and to phone the clinic when the dose has been taken.  
Subjects will return to the clinic for Visit 4 within 5 business days after taking the dose or a maximum of 
28 days after Visit 3. 
9.5 
End of second treatment period (Visit 4)  
Subjects will return to the clinic with their diaries and medication containers at completion of Treatment 
Period 2.  
Blood and urine samples will be taken for safety analysis. 12-lead ECG, vital signs, concomitant 
medications, targeted physical examination results and adverse events will be recorded. Subjects will be 
asked to complete assessments for subject satisfaction for Treatment period 2, if dose taken and overall 
preference for Treatment 1 or 2 if both doses have been taken.   
9.6 
End of study (Visit 5)  
Subjects will be phoned one week after Visit 4 to review any new or changed adverse events or changes 
in concomitant medications.  
9.7 
Early withdrawal visit  
An early withdrawal visit should be conducted within one week of the subject withdrawal, and/or a 
minimum 48 hours after last dose of IMP. 
Subjects who are completing an early withdrawal visit will return with their diaries and unused IMP.  
Blood and urine samples will be taken for safety analysis. 12-lead ECG, vital signs, concomitant

11.1.1 Medical history 
The medical history will include any conditions reported by the subject or noted by the investigator in 
each body system, including allergies or drug sensitivities, past surgeries and any history of substance 
abuse (drug or alcohol), and will be recorded at screening. A review of the subject’s medication use will 
also occur. 
A migraine history, to include frequency, duration and severity of headaches, will be recorded. Sufficient 
information should be collected to confirm the diagnosis, ie intensity, throbbing/nonthrobbing, aggravating 
factors, aura, unilateral or bilateral, associated symptoms, eg photophobia, phonophobia, nausea, 
vomiting, cognitive impairment, dizziness, functional disability, most troublesome symptom.  
11.1.2 Demographics

minutes prior to measurement. All ECG tracings will be reviewed by the Investigator or an appropriately 
medically qualified reviewer designated this responsibility by the Investigator.    
Any subject with an abnormal ECG at screening that is considered clinically significant will be excluded 
from the study. 
11.1.4 Vital signs 
Resting supine or semi-supine blood pressure (systolic and diastolic), heart rate, and respiratory rate will 
be evaluated. The same arm should be used throughout the study. Body temperature (tympanic), will 
also be evaluated as part of vital signs.

vital signs measurement. 
11.1.5 Physical examination 
Physical examinations are to be performed by a medically qualified physician according to their standard 
medical practice. Any new or worsening abnormality, clinical sign or finding must be documented. 
A full physical examination is to be performed at the first screening visit. At other scheduled time points, a 
targeted (symptom directed) physical examination, as clinically indicated, is to be performed.  
A full physical examination will include assessments of the head (eyes, ears, nose, mouth, throat), skin, 
neurological system, respiratory system, cardiovascular system, musculoskeletal system, abdomen (liver 
and spleen), lymph nodes and extremities, general appearance, and any additional assessments needed 
to establish baseline status or change from baseline or evaluate symptoms or adverse events.

11.2 Laboratory assessments 
11.2.1 Clinical safety testing 
Blood samples will be tested at one nominated laboratory per study site. Urinalysis (dipstick) will be 
performed at the investigational site. 
Details of the volume of blood and type of tubes required for the following tests will be provided in the 
Study Manual. At the investigator’s discretion, sample collection may be repeated if an abnormal result 
occurs due to technical or other reasons. 
The following tests will be performed.  
11.2.1.1

including erythrocytes, leucocytes, bacteria, casts, epithelial cells and crystals will be performed. 
11.2.2 Pregnancy  
Human chorionic gonadotropin levels (hCG) will be measured in blood samples from females of child-
bearing potential at screening. Urine hCG will be measured at other time points. 
11.3 Adverse event monitoring 
Subjects will be asked by direct questioning at each visit whether they have experienced any AEs. AEs 
will be assessed as described in Section 13.2. 
11.4 Concomitant medications 
Changes in use or new medications used during course of study will be documented and reviewed at 
each study visit.  
11.5 Efficacy assessments 
11.5.1 Pain intensity 
Migraine pain intensity will be recorded using the NRS in a subject migraine diary at the start of dosing (t

Lateral Pharma Pty Ltd 
 
20190725 lat-mig-001 protocol v1.0_redacted.docx Confidential 
page 44 of 59 
= 0 min) and at 0.5, 1.0, 1.5, 2, 4, 8 and 24 hours post dose. The NRS is an 11-point scale which grades 
pain from 0 (no pain) to 10 (worst pain imaginable). Pain should reflect the subject’s pain at the time of 
recording. 
11.5.2 Migraine symptoms 
Each subject will specify his/her most troublesome symptom at baseline (Day 1).  
On the day of a migraine headache, baseline information about the headache should be recorded to 
verify that the headache was an acute migraine headache including headache intensity, aura, presence 
or absence of associated symptoms, unilaterality or bilaterality of the headache, aggravation by exercise, 
throbbing or nonthrobbing.  
The subject’s symptoms will be recorded on an 11-point Likert scale. This scale allows the subject to 
record the presence of the symptom from 0 = no symptoms to 10 being severe symptoms. Symptom 
assessments will be recorded in the subject’s diary prior to dosing (t = 0 min) and at 0.5, 1, 1.5, 2, 4, 8 
and 24 hours post dose. Symptoms to be recorded include nausea, photophobia and phonophobia plus 
the subject’s most troublesome symptom (eg cognitive impairment, dizziness and functional disability) if 
other than nausea, photophobia or phonophobia. Episodes of vomiting will also be recorded. 
11.5.3 Subject satisfaction 
Subject satisfaction with treatment will be recorded at the end of each treatment period on a 7-point Likert 
scale, with 1 = very satisfied and 7 being very dissatisfied. Subjects will also be asked to record their 
satisfaction compared with their usual anti-migraine therapy. Subjects will be asked to complete the 
satisfaction survey for each Treatment period only if the dose has been taken for that period and the 
Treatment Preference survey only if doses have been taken in both Treatment periods.

12. Study oversight 
12.1 Within-subject stopping criteria  
The following criterion constitutes a contraindication to further administration of IMP to an individual 
subject: 
• 
Any experience, which is considered, by the investigator and/or the sponsor to be serious, 
and severe and clinically significant, which would suggest significant hazard that may be 
associated with the use of the IMP 
If the above criterion becomes applicable during the study, the subject must not receive further doses of 
IMP. Such subjects will be withdrawn and follow the withdrawal procedures as described in Section 5.7. 
12.2 Suspension or premature termination of the study 
Conditions may arise during the study that could prompt the study to be halted or the study site to be 
terminated. The sponsor may terminate part of, or the entire study for safety, administrative, or 
commercial reasons. Conditions that may prompt such considerations include, but are not limited to, the 
following: 
• 
The discovery of unexpected, serious, or unacceptable risk to subjects enrolled in the study; 
• 
A decision on the part of Sponsor to suspend, discontinue, or shorten the study; 
• 
Study conduct at a study site may warrant termination under conditions that include the following: 
o 
Failure of investigator(s) to enrol eligible subjects into the study; 
o 
Failure of the investigator to comply with country-specific regulations; 
o 
Submission of false information from the research facility to the sponsor, the clinical monitor, 
or a regulatory authority; 
o 
Insufficient adherence to protocol requirements; 
o 
A conflict of interest of the investigator, his/her institution, or site personnel that could 
negatively impact the integrity of the clinical study; 
o 
Institution or Ethics Committee under investigation for cause. 
Any decision by the sponsor on stopping or restarting the study must be discussed with the investigator. 
All actions are to be documented and the Ethics committee (EC) and regulatory (competent) authority 
notified in writing as required by local regulations. Should a protocol amendment be required, this will be 
managed in accordance with Section 15.1.4. The study must not recommence recruitment or dosing until 
approval is received in writing from the EC (if/as required by the EC).  
If the study is to be terminated for safety reasons, any further administration of IMP will be stopped.  
If the study is terminated for safety reasons, subjects will be followed up for a minimum of two weeks 
following the last exposure to IMP, at which time an End of study visit should be conducted. Refer to 
Section 9.6 for follow up assessments. Any AEs/SAEs ongoing at the time of the End of study visit will be 
followed to resolution or stabilisation (whichever is the sooner).

13. Adverse events 
13.1 Definitions 
13.1.1 Adverse event  
An adverse event is any untoward medical occurrence in a patient or clinical investigation subject 
administered a pharmaceutical product and may not necessarily have a causal relationship with the 
administered treatment.   
An AE can therefore be any unfavourable and unintended sign (including an abnormal laboratory finding), 
symptom, or disease temporally associated with the use of a medicinal (investigational) product, whether 
or not it is related to the medicinal (investigational) product. This includes an exacerbation of pre-existing 
conditions or events, intercurrent illnesses, drug interaction or any worsening (ie any clinically significant 
adverse change in frequency and/or intensity) of a pre-existing condition, which is temporally associated 
with the use of the sponsor’s product. Anticipated fluctuations of pre-existing conditions, including the 
disease under study, that do not represent a clinically significant exacerbation or worsening need not be 
considered AEs. 
Laboratory reference ranges are defined by upper or lower limits of parameters of the respective 
laboratory. The investigator should ensure that each parameter out of the normal range is assessed for 
clinical significance and the potential for being an AE (refer to Section 13.3). An adverse event is defined 
as ‘serious’ when it meets one of the pre-defined outcomes as described in Section 13.1.6. 
13.1.2 Adverse drug reaction/Suspected adverse (drug) reaction  
An adverse drug reaction (ADR) is any AE for which there is a reasonable possibility that the drug caused 
the AE. Reasonable possibility means there is evidence to suggest a causal relationship between the 
IMP and the adverse event. 
13.1.3 Suspected unexpected serious adverse reactions  
Suspected unexpected serious adverse reactions (SUSARs) are AEs that are believed to be related to an 
IMP and are both unexpected (ie the nature or intensity is not expected from the information provided in 
the Investigator’s Brochure) and serious. SUSARs are subject to expedited reporting to the applicable 
regulatory authorities.  
For regulatory reporting purposes, SUSARS will be unblinded. 
13.1.4 Causality 
The investigator must assign causality to each adverse event in relation to the IMP based on the 
following definitions: 
Not related: 
AE with an incompatible time relationship to IMP administration, and that could 
be explained by underlying disease or other drugs or is incontrovertibly not 
related to the Investigational Product  
Possibly related:  
AE with a reasonable time relationship to IMP administration, but which also 
could be explained by concurrent disease or other medications.  
Probably related:  
AE with a reasonable time relationship to IMP administration that is unlikely to be 
attributed to concurrent disease or other medications.  
Definitely related: 
AE with plausible time relationship to IMP administration and which cannot be 
explained by concurrent disease or concomitant medications.

13.1.5 Severity (intensity) of adverse event 
Grade refers to the intensity of an AE and should not be confused with seriousness (refer Section 13.1.6). 
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; 
hospitalisation or prolongation of hospitalisation indicated; disabling; limiting 
self-care ADL**. 
Grade 4  
Life-threatening consequences; urgent intervention indicated. 
Grade 5  
Death related to AE. 
Activities of daily living (ADL) 
*Instrumental ADL – refers to preparing meals, shopping for groceries or clothes, using the telephone, 
managing money, etc. 
**Self-care ADL – refers to bathing, dressing and undressing, feeding self, using the toilet, taking 
medications, and not bedridden. 
13.1.6 Serious adverse event  
A serious adverse event (SAE) is any untoward medical occurrence or effect that, at any dose: 
• 
Results in death, 
• 
Is life-threatening. 
• 
Life-threatening in the definition of serious refers to an event in which the subject was at risk of 
death at the time of the event, it does not refer to an event which hypothetically might have 
caused death if it were more severe. 
• 
Requires inpatient hospitalisation or prolongation of existing hospitalisation.  
• 
Hospitalisation is defined as inpatient admission or care regardless of duration. Out-patient 
treatment in an emergency room is not in itself an SAE, although the reasons for it may be. 
Elective surgery, or hospital admissions and/or surgical operations planned before or during this 
study are not considered AEs if the illness or disease existed before the subject was enrolled in 
the study, provided that it did not deteriorate in an unexpected way during the study. 
• 
Results in persistent or significant disability/incapacity. 
• 
Is a congenital anomaly/birth defect. 
• 
Is medically important or is a medically significant event.  
Medical and scientific judgement is required to decide if prompt notification is required in situations that 
the investigator regards as medically important that did not strictly meet the criteria above but may have 
jeopardised the subject or required intervention to prevent one of the outcomes listed above, or that 
would suggest any significant hazard, contraindication, side effect or precaution that may be associated 
with the use of the IMP. Such events should also be considered as serious.   
13.2 Recording of adverse events 
In this study, events from Screening to prior to first dose of IMP will be captured as medical history. All 

Protocol Number LAT-MIG-001 
Lateral Pharma Pty Ltd 
 
20190725 lat-mig-001 protocol v1.0_redacted.docx Confidential 
page 48 of 59 
events occurring during and following the first administration of IMP will be reported as AEs or SAEs (if 
criteria met) until the completion of the End of study visit.   
AEs that are ongoing at the End of study visit will be followed up until the event has resolved or 
stabilised. All followup information will be recorded in the subject’s source records. All spontaneously 
volunteered and enquired for, as well as observed AEs, will be recorded in the subject’s source records 
as well as the CRF. 
It is preferable that AEs and SAEs be reported as diagnoses if available, rather than individual signs and 
symptoms. SAEs should be reported and documented in accordance with the procedures in Section 13.4. 
The following data should be documented for each AE: the description of the event, start and stop dates, 
intensity, causality and outcome must be recorded, as well as any actions taken. 
13.3 Clinical lab abnormalities and other abnormal assessments  
Abnormal laboratory findings (eg, clinical chemistry, haematology, and urinalysis) or other abnormal 
assessments (eg, ECG, vital signs) per se are not reported as AEs. However, those abnormal findings 
that are deemed clinically significant or are associated with signs and/or symptoms must be recorded as 
AEs (and recorded as an SAE if they meet the criteria of being serious) as described previously. Clinically 
significant abnormal laboratory or other abnormal findings that are present at baseline and worsen after 
first dose of IMP are to be considered AEs (and SAEs if serious).   
The investigator should exercise his or her medical and scientific judgment in deciding whether an 
abnormal laboratory finding or other abnormal assessment is clinically significant. Usually, the 
abnormality should be associated with a clinically evident sign or symptom, or be likely to result in an 
evident sign or symptom in the near term, to be considered clinically significant. A clinically significant 
laboratory abnormality in the absence of clinical symptoms may jeopardize the subject and may require 
intervention to prevent immediate consequences.    
13.4 Reporting of serious adverse events  
Any SAE must be reported by the investigator if it occurs during the clinical study or within 2 weeks of the 
subject having received the last dose of IMP, whether or not the SAE is considered to be related to the 
IMP. This shall include pregnancy in a female subject or in a female partner of a male study subject. 
Instances of death, congenital abnormality or an event that is of such clinical concern as to influence the 
overall assessment of safety, if brought to the attention of the investigator at any time after cessation of 
IMP administration and linked by the investigator to this study, should be reported to the sponsor.   
The investigator must report an SAE on an SAE report form and forward the SAE report form, the AE 
form and the concomitant medication form to the sponsor or delegate within 24 hours of becoming 
aware of the SAE and regardless of causality. All pregnancies in a female subject or in a female 
partner of a male study subject should be reported on a Pregnancy report form following the same 
reporting process and timelines required for SAEs. 
The investigator should not wait to receive additional information to document fully the event before 
notification of a SAE, though additional information may be requested. Where applicable, information 
from relevant laboratory results, hospital case records and autopsy reports should be obtained. 
Followup information on SAEs must also be reported by the investigational site to the sponsor within the 
same time frame. If a non-serious AE becomes serious, this and other relevant followup information must 
also be provided within 24 hours of the investigator becoming aware. 
All SAEs will be recorded in the subject’s source documents and the CRF.   
It is the responsibility of the sponsor to determine whether a reported SAE fits the classification of a 
SUSAR (refer to Section 13.1.3). If the sponsor considers the SAE to be drug related (ie an adverse drug

page 49 of 59 
reaction), unexpected and fulfils the criteria for a suspected unexpected serious adverse reaction 
(SUSAR), the sponsor has the responsibility to expedite the reporting to all concerned investigators, to 
the EC where required, and to the appropriate regulatory authorities within the pre-defined timelines.  
The investigator must notify their EC of SAEs occurring at the site, within the time period and in 
accordance with requirements specified by the EC.   
The sponsor and/or delegate will promptly notify all relevant investigators and the regulatory authorities of 
findings that could adversely affect the safety of subjects, impact on the conduct of the study or alter the 
ethics approval/favourable opinion of the study.  
13.5 Followup of adverse events and serious adverse events 
All AEs and all SAEs must be followed by the investigator until resolution, or until in the opinion of the 
investigator, the AE has stabilised or is recognised as permanent, or until the subject is lost to follow up, 
whichever comes first. Followup investigations may be necessary according to the investigator’s medical 
judgement.

14. Statistical analysis 
14.1 General considerations 
The statistical analysis principles described below will be supplemented by a comprehensive statistical 
analysis plan (SAP) which will be finalised before the database is locked. This will contain details of 
methods for handling missing data, early withdrawals, data derivations and presentation. Any changes to 
the statistical analysis plan will be described and justified in the final report.  
The descriptive summary for the categorical variables will include counts and percentages. The 
descriptive summary for the continuous variables will include number of subjects (n), means, medians, 
standard deviations, and minimum and maximum values. All data will be listed for all subjects. Treatment 
period order will be ignored in any treatment comparisons. Results will be presented in a descriptive 
format by treatment within each treatment period and overall. Treatment comparisons will take into 
account the paired nature of the treatment responses where feasible. As this is a Phase IIa proof of 
concept study, no formal statistical hypotheses are being specified although some may be investigated 
as part of the data presentation, in which case corresponding 95% confidence intervals will be presented 
and p-values of <0.05 will be declared statistically significant. 
14.2 Sample size 
No formal statistical sample size estimation has been performed due to the exploratory nature of this 
study. Rather the sample size is based on clinical and practical considerations. 
14.3 Analysis populations 
14.3.1 Full analysis set 
The Full analysis set (FAS) consists of all subjects enrolled and randomised into the study. The FAS 
population will be used for summaries of subject disposition, demographic and baseline characteristics. 
Subjects will be analysed according to the treatment group they were assigned at randomisation. 
14.3.2 Per protocol population 
A per-protocol (PP) population will be used for efficacy analyses and to analyse exploratory endpoints. 
The PP population will be based on IMP exposure, including the time of any episodes of vomiting and 
major protocol deviations.  
14.3.3 Safety population 
The safety population consists of all randomised subjects who receive at least one dose of IMP. The 
safety population will be used for the analysis of safety and tolerability data. Subjects will be analysed as 
treated, regardless of the randomised treatment assigned, if this differs from that to which the subject was 
randomised. 
14.4 Subject disposition 
The total number of subjects will be summarised. The duration on study, and number of subjects 
terminating the study treatment early, along with the reason for early study treatment termination will also 
be summarised. 
14.5 Analysis of efficacy data 
The primary population for analysis of efficacy data is the PP population. All summary tables and results 
of statistical analyses will be presented for the PP population for all efficacy endpoints. In addition, all

Lateral Pharma Pty Ltd 
 
20190725 lat-mig-001 protocol v1.0_redacted.docx Confidential 
page 51 of 59 
summary tables and results will be presented for the FAS population. 
Individual pain score-time profiles for each treatment within each subject will be presented graphically. 
The difference between the NRS pain scores at each timepoint for LAT8881 60 mg compared with 
placebo within each subject will be estimated and presented graphically. The number of subjects, mean, 
standard deviation, minimum and maximum NRS pain score at each timepoint, change from baseline, 
difference between treatments at each timepoint and change from baseline difference between 
treatments will be presented for each treatment overall and within each treatment period. 
Nausea, photophobia and phonophobia symptom scores will be summarised and presented in the same 
way as the pain scores. The number and percent of headaches with each most troublesome symptom of 
migraine including nausea, cognitive impairment, dizziness, functional disability, photophobia and 
phonophobia will be summarised for each treatment. The most troublesome symptom scores will be 
summarised and presented in the same way as the pain scores. 
The number and percent of subjects with 'no headache pain' at each time point will be presented for each 
treatment. Two-way tables will present the presence/absence of pain classified for each treatment at 
each timepoint. Absence of pain will be defined as a pain NRS score of 0 or 1. 
The number and percent of subjects who are “sustained pain-free” at 24 hours after dose of IMP will be 
presented by treatment. A two-way table will present the “sustained pain-free” status for subjects on each 
treatment.  
The number and percent of subjects will be summarised by their first pain-free timepoint. A two-way table 
will present the classification of each subject’s first pain-free timepoint by treatment. Kaplan-Meier curves 
will present the time to first pain-free timepoint.  
Patient satisfaction for each treatment recorded on a 7-point Likert scale and the within-subject difference 
between treatments will be summarised. The mean difference between treatments will be compared with 
a paired t-test and the 95% confidence interval for the mean difference will be presented. Additional 
exploratory analyses to investigate the association between change in headache pain and symptom 
scores and selected subject baseline characteristics will be undertaken in a similar fashion with 
descriptive statistics. 
14.5.1 Analgesic use 
Rescue medication use over the treatment period will be listed for each subject. 
14.6 Analysis of safety data 
14.6.1 Extent of exposure 
The number of subjects exposed to study treatment, and total IMP administered within each period and 
overall, will be summarised.  
14.6.2 Adverse events 
Adverse events will be coded using the Medical dictionary for regulatory activities (MedDRA) and 
summarised by system organ class (SOC) and preferred term (PT).  
A summary of the number and percentage of subjects with the following adverse events will be prepared: 
• 
All adverse events 
• 
Serious adverse events 
• 
Adverse events leading to premature discontinuation of IMP

20190725 lat-mig-001 protocol v1.0_redacted.docx Confidential 
page 52 of 59 
• 
Adverse events by intensity 
• 
Adverse events by relationship to IMP 
All summaries of adverse events will include only treatment emergent adverse events (TEAEs). Refer 
Section 13.1 for adverse event definitions. 
14.6.3 Clinical laboratory evaluations 
Safety laboratory data (haematology, biochemistry, and urinalysis) will be summarised by visit and 
treatment. All laboratory data will be included in the data listings. In addition, a separate listing of 
laboratory data for subjects with clinically significant abnormal results will be prepared. 
14.6.4 Other safety measures 
Vital signs (body temperature, respiratory rate, heart rate, and blood pressure) will be summarised by 
baseline and treatment overall and for each treatment within the treatment sequence. Changes over time 
in vital signs will be summarised. 
Physical examination data will be listed only.  
The number and percentage of subjects receiving concomitant medications will be tabulated overall and 
by medication received.

15. Study management 
15.1 Regulatory and ethical considerations 
15.1.1 Regulatory compliance and ethical conduct 
This study must be conducted in compliance with the study protocol, the requirements and obligations of 
the International Conference on Harmonisation (ICH) and Good Clinical Practice (GCP) guidelines, 
Integrated Addendum to ICH E6(R1): Guideline for Good Clinical Practice E6(R2),1 the World Medical 
Association Declaration of Helsinki16 and its amendments and all applicable local guidelines, laws and 
regulations.   
Investigators and other site personnel will undergo appropriate study-specific training during the study 
site initiation visit. Before initiation of the study at the site(s), the written approval / favourable opinion of 
the local and/or national independent ethics committee(s) and relevant health authority(ies) will be sought 
and obtained.   
15.1.2 Ethics committee review 
Prior to the initiation of the study, the protocol and associated documentation (including all materials used 
to recruit subjects for the study) must be given a favourable opinion by an ethics committee (EC). A copy 
of this written approval and any correspondence with the EC will be provided to the sponsor.  
The investigator must obtain approval from the sponsor before potential subjects can undergo any study-
specific screening procedures. 
The investigator will comply with any additional requirements imposed by the EC. The investigator must 
submit progress reports to the EC according to local regulations and guidelines. The investigator must 
also provide their EC with any reports of SAEs from the study site in accordance with the EC’s 
requirements and timelines.  
15.1.3 Informed consent process 
The investigator will ensure that the subject is given full and adequate oral and written information about 
the nature, purpose, possible risks and potential benefits of the study. Subjects must also be notified that 
they are free to discontinue from the study at any time. The subject should be given the opportunity to 
ask questions and should be allowed time to consider the information provided. 
The subject’s signed and dated informed consent must be obtained before conducting any procedure 
specifically for the study. The investigator must store the original, signed ICF with the subject’s medical 
records. A copy of the signed and dated ICF must be given to the subject.  
Subjects who are incompetent and unable to freely provide informed consent and subjects who are 
unable to read or speak English without the assistance of an interpreter will not be invited to participate in 
the study. 
If new information arises during the study that may affect the safety of the subjects, the protocol and ICF 
will be amended as appropriate and submitted to the EC as outlined in Section 15.1.4. Following approval 
by the EC, subjects will be advised by letter of any safety related updates that may impact during the 
post-study period and be invited to discuss any concerns with the investigator. When applicable, subjects 
may be requested to re-consent to ongoing their participation in the study. 
15.1.4 Protocol amendments 
The signed, EC-approved protocol must not be changed without the agreement of the sponsor. If it is 
necessary for an EC-approved study protocol to be amended, the relevant EC and, if required, the local 

Protocol Number LAT-MIG-001 
Lateral Pharma Pty Ltd 
 
20190725 lat-mig-001 protocol v1.0_redacted.docx Confidential 
page 54 of 59 
regulatory authority must be informed and asked for its opinion as to whether a re-evaluation of the 
ethical aspects of the study is necessary.  
The investigator must not implement any deviation from, or change to the protocol, without agreement by 
the sponsor and prior review and documented approval/favourable opinion of the amendment from the 
relevant EC, except where it is necessary to eliminate an immediate hazard to study subjects, or where 
the change(s) involve(s) only logistical or administrative aspect(s) of the study, for example, change in 
monitor(s) or change of telephone number(s). 
If a protocol amendment requires a change to the Participant information sheet (PIS) or Informed consent 
form (ICF), approval of the revised PIS and ICF by the sponsor and EC is required before the updated 
document can be used. 
Following approval, the sponsor (or delegate) will distribute new versions of amended documents (eg 
protocol, PIS, ICF) to the site.  
15.1.5 Protocol deviations  
No deviations from or changes to the protocol will be implemented without documented approval from the 
EC of an amendment, except where necessary to eliminate an immediate hazard(s) to study subjects or 
when the change(s) involves only logistical or administrative aspects of the study. 
Any deviations from or changes to the protocol which were implemented to eliminate an immediate 
hazard and the proposed amendment, if appropriate, should be submitted to the EC for review and 
approval as soon as possible. 
Should any protocol deviation occur, it must be reported to the study monitor as soon as is reasonably 
practical. If a major protocol deviation occurs, the investigator must notify the sponsor and the 
appropriate EC as soon as possible or as per local requirements.  
All instances of noncompliance with the requirements of the Study protocol will be captured in a Protocol 
deviation log. The deviation and the reason for its occurrence must be documented, reported to the 
relevant EC (if required) and included in the clinical study report. 
15.2 Quality control and quality assurance 
15.2.1 Training of staff  
Each individual involved in the study must be qualified by education, training and experience to perform 
his or her respective tasks.   
Site staff may be trained at investigator meetings and initiation visits by the sponsor or their designees.  
15.2.2 Study monitoring 
The study will be independently monitored in accordance with ICH GCP1, and applicable local regulations.  
Before the start of the study, a study monitor appointed by the sponsor will evaluate the investigational 
site to ensure facilities are adequate and to discuss responsibilities with the site staff with regards to 
following the protocol and regulatory and ethical requirements. 
During the study, the study monitor will regularly visit the site to monitor and confirm protocol, regulatory 
and ethical adherence, confirm data accuracy and provide information and support as needed. 
The investigator is responsible for maintaining source documents. The investigator must agree to allow 
the study monitor direct access to all relevant documents at each monitoring visit, including electronic 
medical records, and to allocate their time and the time of their staff to the study monitor to discuss 
findings and any relevant issues. 

Protocol Number LAT-MIG-001 
Lateral Pharma Pty Ltd 
 
20190725 lat-mig-001 protocol v1.0_redacted.docx Confidential 
page 55 of 59 
Site staff will be provided with contact details for the study monitor and back-up persons in the event they 
have queries or require assistance. 
15.2.3 Data management and quality control 
The sponsor (or delegate) will be responsible for activities associated with the data management of this 
study. This will include setting up a database and data transfer mechanisms, along with appropriate 
validation of data and resolution of queries. 
Data generated within this clinical study will be handled according to the relevant SOPs of the sponsor 
and/or their delegate(s). An electronic CRF (eCRF) will be created by the data management group for 
recording of the required data and integration into the study database. All data (including electronically 
available data, ie eCRF and laboratory data) will be integrated into a validated Data Management System 
with full audit trail capability (ie a computerised log of all subsequent changes to the data will be 
recorded). Automated checks will be made against the data to ensure completeness and consistency. 
The database and check programs will be validated before implementation. AEs will be coded using 
MedDRA and medications will be coded using the current version of the WHO drug dictionary. 
Missing or inconsistent data will be queried via system generated queries to the investigator for 
clarification. Subsequent modifications to the database will be documented. 
Data collection and entry into the eCRF will be completed by authorised study site personnel designated 
by the investigator. Appropriate training and security measures will be completed with the investigator 
and all authorised study site personnel prior to the study being initiated and any data being entered for 
any study subjects. 
The eCRFs should always reflect the latest observations on the subjects participating in the study; 
therefore, the eCRFs are to be completed as soon as possible during or after the subject’s visit. The 
investigator must verify that all data entries in the eCRFs are accurate and correct. If some assessments 
are not done, or if certain information is not available or not applicable or unknown, this should be 
indicated in the eCRF. The investigator will be required to sign off on the final clinical data. 
During the study the study monitor will review the eCRFs and evaluate them for completeness and 
consistency. The eCRF will be compared with the source documents to ensure that there are no 
discrepancies. All entries, corrections and alterations are to be made by the investigator or designee.  
The study monitor cannot enter data into the eCRFs. If corrections are needed, the responsible study 
monitor or data manager will raise a query and the appropriate investigational staff will be required to 
provide an answer. All queries and resultant data changes will have an electronic audit trail, meaning that 
the name of the investigational staff responding to the query, time and date stamp are captured.  
The eCRF is considered a data entry form and should not constitute the original, or source document, 
unless otherwise specified. Source documents are documents used by the investigator or study site that 
relate to the subject’s medical record, that verify the existence of the subject, the inclusion and exclusion 
criteria and all records covering the subject’s participation in the study. They include, but are not limited 
to, laboratory reports, hospital records, subject files, etc. 
eCRFs will be completed for subjects who have signed the ICF, are eligible for this study and have been 
enrolled in the study. 
15.2.4 Audits and inspections 
An audit is a systematic and independent examination of study related activities and documents to 
determine whether the evaluated study activities were conducted and the data were recorded, analysed 
and accurately reported according to the protocol, the sponsor’s standard procedures or those of the 
sponsor’s designees, ICH GCP and applicable regulatory requirements.  

Protocol Number LAT-MIG-001 
Lateral Pharma Pty Ltd 
 
20190725 lat-mig-001 protocol v1.0_redacted.docx Confidential 
page 56 of 59 
In accordance with ICH GCP, this study may be selected for audit. Inspection of site facilities (eg 
pharmacy, medication storage areas, laboratories) and review of study-related records may occur by the 
sponsor, sponsor’s representative, ethics committee or regulatory authority to evaluate the study conduct 
and compliance with the protocol, ICH GCP, and applicable regulatory requirements. 
The regulatory authority or ethics committee inspectors are responsible for contacting and visiting the 
investigative site for the purpose of inspecting the facilities, if required, and, upon request, inspecting the 
various records of the study (eg source documents, CRFs, essential documentation, and other pertinent 
data) ensuring that subject confidentiality is respected. 
The investigator should contact the sponsor or designee immediately if they are contacted by a regulatory 
agency or Ethics Committee about an inspection at their centre. If an audit or inspection occurs, the 
Investigator and institution agree to allow the auditor/inspector direct access to all relevant documents 
and allocate their time and the time of their staff to the auditor/inspector to discuss findings and any 
relevant issues.  
15.3 Documentation, record access and archiving 
15.3.1 Maintenance of essential documents/supplements at study site during the study 
At the beginning of the study, an Investigator’s Study File will be established at the study sites. The 
investigator/institution is responsible for maintaining the study documents during the study as specified in 
the ICH GCP1 guidelines and applicable regulatory requirement(s). The investigator/institution must take 
measures to prevent accidental or premature destruction of these documents.  
These files must be suitable and available for inspection at any time by the sponsor, study monitor, 
and/or applicable regulatory authorities.    
15.3.2 Data protection 
To protect the subject’s identity, a unique subject identification code (Subject ID) will be assigned by the 
investigator to each study subject and used in lieu of the subject’s name when the investigator reports 
SAEs and/or other study related data. The subject’s study number, rather than the subject’s name, will 
appear on all documents. 
Personal information will be treated as confidential, but may need to be reviewed by authorised 
representatives of the sponsor (and/or delegate), the EC and regulatory authority(ies). The subject’s 
consent to direct access to his/her original medical records for data verification purposes must be 
obtained prior to that subject’s involvement in the study. 
Subjects will be informed that data will be held on file by the sponsor and that these data may be viewed 
by staff including the study monitor and by external auditors on behalf of the sponsor and appropriate 
regulatory authorities. Subjects will also be informed that a study report will be prepared and may be 
submitted to regulatory authorities and that the study results may be published. However, subjects will be 
identified in such reports only by study identification number (Subject ID), gender and age. All subject 
data will be held in strict confidence. 
The PIS will explain that electronic study data will be stored in a computer database, maintaining 
confidentiality in accordance with the applicable local privacy regulations. Subject data in the database 
will be identified by Subject ID number only. Electronic CRFs will also identify subjects by Subject ID only 
and will be maintained and stored in accordance with the applicable local privacy regulations.  
The PIS will also explain that for data verification purposes, authorised representatives of the 
investigator, sponsor, regulatory authorities or ECs may require direct access to parts of the hospital or 
practice records relevant to the study including the subject’s source documents and/or medical record.

page 57 of 59 
15.3.3 Data retention & archiving  
All study records (including the Investigator’s Study File containing Essential Documents as defined in 
ICH GCP1) and source data must be available for retrospective review or audit.   
Source documents are original documents, data, and records from which the subject’s CRF data are 
obtained. These include, but are not limited to: hospital records, subject’s source documents/files, clinical 
and office charts, laboratory and pharmacy records, diaries, radiographs, IMP accountability logs, and 
correspondence. CRF entries may be considered source data if the CRF is the site of the original 
recording (ie, there is no other written or electronic record of data). In this case, a note to the file should 
indicate which CRFs data points are considered source data. 
At completion of the study the investigator is responsible for the archiving of the study records for their 
site.   
All source data, clinical records and laboratory data relating to the study must be archived for no less 
than 2 years after the last approval of a marketing authorisation application in an ICH region and until 
there are no pending or contemplated marketing applications in an ICH region, or at least two years have 
elapsed after formal discontinuation of clinical development of the IMP. Study documents should be 
retained for a longer period as required by local regulatory requirements or by an agreement with the 
sponsor. In Australia, records should be retained by the trial sponsor for at least 15 years following 
completion of the trial. It is the responsibility of the sponsor to inform the investigator/Institution as to 
when the documents no longer need to be retained.  
No study document should be destroyed without prior written agreement between the sponsor and the 
investigator. If the investigator leaves the Institution, the responsibility for all study documents must be 
transferred to another person at the institution. If the investigator wishes to assign the study records to 
another party or move them to another location, he/she must notify the sponsor in writing of the new 
responsible person and/or the new location.  
15.4 Study administration 
15.4.1 Study agreements 
Financing and insurance of this study will be outlined in separate agreement(s) between the sponsor and 
all relevant parties. 
Payments will relate to the number of subjects as well as the cost of clinical visits, laboratory 
investigations and other services outside of normal routine examinations and specifically connected with 
the conduct of this study. This agreement will cover payment for eCRFs fully completed in conformity with 
the protocol. The fee for subjects who withdraw prematurely from the study will be on a pro-rata basis 
reflecting the percentage of study activities completed. 
Neither the sponsor nor its designee is financially responsible for further testing/treatment of any medical 
condition that may be detected during the screening process. In addition, in the absence of specific 
arrangements, neither the sponsor nor its designee is financially responsible for further treatment of the 
subject’s condition beyond the time period specifically outlined in this protocol. 
The investigator(s) must comply with all the terms, conditions and obligations of the study agreement for 
this study. In the event of any inconsistency between this protocol and the study agreement, the study 
agreement shall prevail. 
15.4.2 Confidentiality 
In signing the final protocol, every participating investigator agrees to keep all information and results 
concerning the study and the investigational product confidential for as long as the data remain 

Protocol Number LAT-MIG-001 
Lateral Pharma Pty Ltd 
 
20190725 lat-mig-001 protocol v1.0_redacted.docx Confidential 
page 58 of 59 
unpublished. The confidentiality obligation applies to all personnel involved at the study site. However, 
authorised regulatory officials and the sponsor’s personnel (or their representatives) will be allowed full 
access to inspect and copy the records. All IMPs, subject bodily fluids and/or other materials collected 
shall be used solely in accordance with this protocol, unless otherwise agreed to in writing by the sponsor 
and the EC. 
All CRFs as well as all reports and communications relating study involvement will identify each subject 
only by the subject identification code (Subject ID). The investigator will maintain a current confidential 
Subject Identification List of full names of all subjects in this study. This list will allow the investigator to 
reveal the identity of the subjects if they need to be contacted for safety reasons. This information will be 
held in the strictest confidence and will only be used if needed for emergency purposes. 
15.4.3 Insurance 
The sponsor has appropriate liability insurance cover available to enable it to indemnify and hold the 
investigator(s) and relevant staff as well as any hospital, institution, EC or the like, harmless from any 
claims for damages for unexpected injuries, including death, that may be caused by the IMP but only to 
the extent that the claim is not caused by the fault or negligence of the subjects or investigator(s). This 
insurance is held in accordance with the applicable local legal requirements.  
Further details of this and financial arrangements are specified in the agreements with the study site.
