SUMMARY OF AMENDED PROTOCOL CHANGES 
PROTOCOL VERSION 2.0 (AMENDMENT 1) 
This amendment to the Final Study Protocol, dated 11 October 2018, has been issued to add a 
study restriction to minimise exposure to ultraviolet (UV) light as recommended by the 
Medicines and Healthcare products Regulatory Agency (MHRA). 
Details of the changes incorporated in this amendment are provided in the table below. 
Protocol Section 
Description of Changes from Final Protocol, dated 11 October 2018 
1.5 
New text added in bold: 
In albino and pigmented mice, [14C]-GB1211-related radioactivity was 
well absorbed and rapidly distributed into tissues, [14C]-GB1211-related 
radioactivity was rapidly eliminated from tissues, and the mean overall 
recovery of the radioactivity administered was 103%. GB1211 showed a 
trend for distribution to the uveal tract and skin of pigmented mice. 
This was reversible and below the limit of quantification at 168 
hours. 
4.4 
Addition of exclusion criterion 20: 
Subject is not willing to minimise or avoid exposure to natural or 
artificial sunlight (tanning beds or UVA/B treatment) following 
administration of study drug until 24 hours after the last dose. 
4.5 
Addition of exclusion criterion 20: 
Subject is not willing to minimise or avoid exposure to natural or 
artificial sunlight (tanning beds or UVA/B treatment) following 
administration of study drug until 24 hours after the last dose. 
4.6 
Addition of exclusion criterion 26: 
Subject is not willing to minimise or avoid exposure to natural or 
artificial sunlight (tanning beds or UVA/B treatment) following 
administration of study drug until 24 hours after the last dose.

6.6. Exposure to Ultraviolet Light 
Subjects should minimise or avoid exposure to natural or artificial 
sunlight (tanning beds or UVA/B treatment) following 
administration of study drug until 24 hours after the last dose. If 
subjects need to be outdoors during this period, they should wear 
loose fitting clothes that protect skin from sun exposure and discuss 
other sun protection measures with the Investigator.

SYNOPSIS 
Title of study: GB1211 – A Randomised, Double-Blind, Placebo-Controlled, First-In-Human, 
Study of Orally Administered GB1211 to Evaluate the Safety, Tolerability, and Pharmacokinetics 
of Single Ascending Doses (SAD) and Multiple Ascending Doses (MAD) in Healthy Subjects and 
in Subjects with Suspected Nonalcoholic Steatohepatitis (NASH) and Liver Fibrosis 
Objectives:  
The primary objectives of the study are: 
• 
to evaluate the safety and tolerability of single and multiple doses of GB1211 administered 
to healthy subjects. 
• 
to evaluate the safety and tolerability of multiple doses of GB1211 administered to subjects 
with suspected NASH and liver fibrosis. 
The secondary objectives of the study are: 
• 
to evaluate the pharmacokinetics (PK) of single doses of GB1211 in plasma and urine in 
healthy subjects, and the PK of multiple doses of GB1211 in plasma of healthy subjects and 
subjects with suspected NASH and liver fibrosis 
• 
to determine the effect of food on the single oral dose PK of GB1211. 
The exploratory objectives of the study are: 
• 
to investigate biomarkers related to GB1211 activity at single and/or multiple doses in 
comparison to placebo in healthy subjects and subjects with suspected NASH and liver 
fibrosis. 
• 
to investigate biomarkers of metabolism, inflammation, and fibrosis following multiple 
doses of GB1211 in healthy subjects and/or subjects with suspected NASH and liver 
fibrosis.  
• 
to identify metabolites of GB1211 in plasma and urine. 
Study design: 
This is a Phase 1, randomised, double-blind, placebo-controlled, first-in-human study in which the 
safety, tolerability, and PK of orally administered GB1211 will be assessed in healthy adult subjects 
and adult subjects with suspected NASH and liver fibrosis. 
Suspected NASH is defined as the presence or history of fatty liver, together with elevated alanine 
aminotransferase (ALT), plus either confirmed type 2 diabetes mellitus (T2DM) or metabolic 
syndrome, in the absence of any other liver disease. Additional criteria aim to enrich for individuals 
with liver fibrosis (as per inclusion criteria). 
The study will consist of 3 parts: a SAD phase (Part A) enrolling a total of 5 cohorts of healthy 
subjects; a MAD phase (Part B) enrolling 2 cohorts of healthy subjects; and an optional Part C 
MAD phase enrolling 1 cohort of subjects with suspected NASH and liver fibrosis. One cohort of 
Part A will receive GB1211 under both fasted and fed conditions to investigate the effect of food. 
Number of subjects: 
Part A: 40 subjects will be studied in 5 cohorts (Cohorts A1 to A5) 
Part B: 22 subjects will be studied in 2 cohorts (Cohorts B1 to B2) 
Part C: 25 subjects will be studied in 1 cohort (Cohort C1)

60 years (inclusive) for Part B; with a body mass index (BMI) ≥ 18.0 kg/m2 and ≤ 32.0 kg/m2, who 
must be healthy, as determined by no clinically significant findings from medical history, physical 
examination, 12-lead electrocardiogram (ECG), vital signs measurements, and clinical laboratory 
evaluations (congenital nonhaemolytic hyperbilirubinemia [eg, suspicion of Gilbert’s syndrome 
based on total and direct bilirubin] is not acceptable) at Screening and Check-in as assessed by the

following: magnetic resonance imaging (MRI) suggesting liver fat ≥ 8%, ultrasound (US) indicating 
fatty liver, or Fibroscan Controlled Attenuation Parameter (CAP) > 270 dB/m. In subjects without a 
documented history of fatty liver, a Fibroscan CAP or US can be performed at Screening. Subjects 
with a Fibroscan CAP > 270 dB/m or US indicating fatty liver are eligible. In addition, subjects 
should have metabolic syndrome (Adult Treatment Panel III definition) or T2DM (defined as stable 
diabetes with glycosylated haemoglobin (HbA1c) ≤ 9.5%); have ALT ≥ 20 U/L for females and 
≥ 30 U/L for males at Screening; and have Fibroscan ≥ 7 KPa and < 13 KPa, or Fibrosis-4 (FIB-4) 
index ≥ 1.1 and < 3.25.

Test products: 5 and 50 mg GB1211 capsules 
Proposed dose levels for Part A: 5, 20, 50, 100, and 200 mg 
Proposed dose levels for Part B: to be determined based on data from Part A.  
Proposed dose level for Part C: to be determined based on data from Part A, and data from at least 
1 Part B cohort. 
The dosing frequency/interval and dosing duration for Part B will be fully decided, in consultation 
with the Sponsor, on the basis of data from Part A; and for Part C, will be fully decided on the basis 
of data from Part A and at least 1 Part B cohort. The daily dose administered will not exceed the 
highest dose administered in Part A. 
Administration route: oral 
Reference product and mode of administration: 
Reference product: placebo capsules 
Administration route: oral 
Duration of subject participation in the study: 
Planned Screening duration: approximately 4 weeks. 
Planned study duration (Screening to Follow-up):  
   Part A, Cohorts A1 to A5 (excluding food-effect cohort, planned to be Cohort A3: approximately   
5 weeks.  
   Part A, Food-effect cohort (planned to be Cohort A3): approximately 6 to 7 weeks. 
   Part B: approximately 6 to 7 weeks. 
   Part C: approximately 11 weeks.

Endpoints: 
Primary endpoints: 
Incidence and severity of adverse events, incidence of laboratory abnormalities (haematology, 
clinical chemistry, urinalysis), 12-lead ECG parameters, vital signs measurements, and physical 
examinations. 
Secondary endpoints: 
Blood samples for the analysis of plasma concentrations of GB1211 following single and multiple 
oral doses of GB1211. In addition, urine samples for the analysis of urinary concentrations of 
GB1211 following single oral doses of GB1211 (Part A). 
The PK parameter endpoints for Part A will include area under the plasma concentration-time curve 
(AUC) from time zero to infinity (AUC0-∞), AUC from time zero to the time of the last quantifiable 
concentration (AUC0-tlast), maximum observed plasma concentration (Cmax), time of the maximum 
observed plasma concentration (Tmax), apparent plasma terminal elimination half-life (t1/2), apparent 
total plasma clearance (CL/F), apparent volume of distribution (Vz/F), amount of drug excreted in 
urine (Ae), percentage of dose excreted unchanged (fe) in urine, and renal clearance (CLR). In 
Parts B and C, the PK parameters will include AUC over a dosing interval (AUC0-τ), AUC0-∞, Cmax, 
Tmax, t1/2, minimum observed plasma concentration (Cmin), observed accumulation ratio based on 
AUC0-τ (RAAUC0-τ), and observed accumulation ratio based on Cmax (RACmax). Other PK parameters 
may also be reported. 
Exploratory endpoints: 
For all SAD and MAD cohorts (Parts A, B, and C), exploratory biomarker endpoints include serum 
galectin-3, chemokine (C-C motif) ligand (CCL)-4 (CCL4), and other biomarkers may also be 
measured in an exploratory fashion. For all MAD cohorts (Parts B and C), changes from baseline at 
Day 10 (healthy subjects) and Day 42 (subjects with suspected NASH and liver fibrosis) will be 
assessed in fasting plasma glucose and insulin; in lipid profile; in heat shock C-reactive protein 
(hsCRP), interleukin (IL)-12, monocyte chemotactic protein (MCP)-1, tumor necrosis factor (TNF)-
alpha, CCL2, CCL3, CCL4 and the chemokine (C-C motif) receptors (CCR)-1 and CCR2; and 
other biomarkers of inflammation as required. For the MAD cohort in subjects with suspected 
NASH and liver fibrosis (Part C), changes from baseline at Day 42 in biomarkers of fibrosis, 
including but not limited to extracellular matrix proteins (tissue inhibitor of matrix 
metalloproteinase-1 [TIMP-1], hyaluronic acid [HA], and aminoterminal peptide of pro-collagen III 
[P3NP]), A9, E74-like transcription factor (ELF) panel, cytokeratin (CK)-18, plasminogen activator 
inhibitor (PAI)-1, chitinase-3-like protein-1 (CH3L1), IL6, and pro-collagen 3. In addition, 
identification of GB1211 metabolites in plasma and urine. 
Statistical methods: 
Pharmacokinetics: 
Individual plasma and urine concentrations of GB1211 (Part A only for urine concentrations) will 
be listed and summarised using descriptive statistics. Individual and mean GB1211 
concentration-time profiles will be presented graphically.  
Where data are available, GB1211 dose proportionality will be examined across the dose cohorts. 
The PK parameters will be analysed for dose proportionality using a power model approach or 
analysis of variance (ANOVA) model as appropriate. Where data are available, the effect of food at 
1 dose level in Part A will be investigated using an ANOVA model. 
Exploratory biomarker data: 
Exploratory biomarker data will be listed and summarised using descriptive statistics. No formal 
statistical analysis of exploratory biomarker data is planned. 
Safety: 
Safety parameters will be listed and summarised using descriptive statistics. No formal statistical 
analysis of safety data is planned.

1. INTRODUCTION 
1.1. 
Overview 
Galectin-3, a beta-galactoside binding lectin, is a key regulator of fibrosis and inflammation 
in lung, liver, and kidney. Mice deficient in galectin-3 are protected from fibrosis and exhibit 
reduced scarring in response to injury. Galectin-3 regulates myofibroblast differentiation (the 
major source of collagens during tissue fibrosis) and also has profound effects on 
macrophage polarisation. In addition, secretion of galectin-3 by macrophages results in 
activation of myofibroblasts, further amplifying a pro-fibrotic loop.1,2 Galectin-3 inhibitors, 
when delivered locally in the lung, have also been shown to reduce fibrosis in mice.3,4  
Nonalcoholic fatty liver disease (NAFLD) affects about a third of the adult population in 
Western nations, and may manifest histologically as a fatty liver or steatohepatitis. Fatty liver 
is generally non-progressive or progresses slowly compared to nonalcoholic steatohepatitis 
(NASH), which is more likely to lead to progressive fibrotic remodelling of the liver 
culminating in cirrhosis. Prevalence of NASH cirrhosis is growing and it is at present, the 
second leading cause for liver transplantation. There is no approved therapy for NASH or 
NASH fibrosis.  
The gold standard methodology for the diagnosis on NASH is liver biopsy. Nonalcoholic 
steatohepatitis is characterised by a pattern of injury composed of steatosis, lobular 
inflammation, and ballooning degeneration. Liver biopsy is an invasive methodology and 
subject to a certain degree of sampling variability; however, there are no noninvasive tools to 
diagnose definite NASH with enough accuracy to serve as a stand-alone entry criteria for 
advanced phase trials and to avoid using histology-based endpoints. However, in early proof 
of concept trials, noninvasive models are generally used to identify those who may have 
definite NASH with some degree of fibrosis (“suspected NASH with liver fibrosis”).5 
Galecto Biotech is developing a systemically active galectin-3 inhibitor for the treatment of 
fibrotic disorders such as NASH, renal fibrosis, and cardiac fibrosis. This is the first time 
GB1211 will be administered to humans. Additional details on GB1211 can be found in the 
Investigator’s Brochure (IB).6  
1.2. 
Summary of Nonclinical Pharmacology 
In 2 primary pharmacodynamic (PD) studies, the effect of GB1211 on carbon 
tetrachloride-induced liver fibrosis in mice was evaluated. The percentage area of Picrosirius 
Red positive staining in liver sections was significantly reduced in animals given 10 mg/kg 
GB1211 twice daily (BID; p = 0.009), indicating decreased fibrotic collagen deposition in the 
hepatic parenchyma; and significantly reduced (p ≤ 0.05) in once daily and BID groups in a 
second study. The collagen content, measured by hydroxyproline, was also found to be 
significantly reduced in the BID group of one study. There were no clear significant changes 
in liver function, liver fibrosis biomarkers, or indicators of the collagen life cycle, with the 
exception of increased serum ALT with 10 mg/kg GB1211 BID in 1 study. In a secondary 
PD study, GB1211 showed no cross-reactivity against an industry standard panel of 87 
enzyme and radioligand binding assays.

1.3. 
Summary of Safety Pharmacology 
In a Good Laboratory Practice (GLP) study in male CD-1 mice, no effects were observed on 
the central nervous system or body temperature or respiratory parameters when given a single 
oral dose of up to 500 mg/kg. In another GLP study in male telemeterized Beagle dogs, no 
effects were observed on hemodynamic or electrocardiography parameters, or body 
temperature, when given a single oral dose of up to 50 mg/kg. In 6-week repeat-dose toxicity 
studies, there was also no evidence of gastrointestinal toxicity or renal toxicity in mice or 
dogs; and GB1211 was negative in all genotoxicity studies.  
In addition, 2 human ether-à-go-go-related gene (hERG) studies were conducted. In the 
non-GLP study, GB1211 significantly (p ≤ 0.05) inhibited the hERG tail current density at 1 
and 10 μM by 16.8% and 35.9%, respectively. There was no evidence of reversal based on 
measures taken after a 5-minute washout period in cells exposed to 10 μM. In the GLP study, 
GB1211 significantly (p < 0.05) inhibited the hERG tail current amplitude at all 
concentrations (6.83%, 28.51%, 57.60%, and 93.33% for 0.3, 1, 10, and 100 μM, 
respectively). The half maximal inhibitory concentration (IC50) was 5.06 μM (2700 ng/mL). 
1.4. 
Summary of Toxicology 
As detailed in Section 4.3 of the IB6, repeat-dose toxicity studies were conducted in 2 species, 
the CD-1 mouse and Beagle dog: 
• In 2 mice repeat-dose toxicity studies, there were no GB1211-related deaths.  
o In a non-GLP study, there were no significant findings in mice given single 
escalating oral doses up to 500 mg/kg, or daily oral doses at 500 mg/kg/day 
for 14 days.  No effects on body weights, food consumption, clinical 
pathology, organ weights, or macroscopic or microscopic findings were 
observed. Systemic saturation was observed at doses > 50 mg/kg/day. 
o In the 6-week GLP study (doses of 50, 150, and 500 mg/kg/day), there were 
no GB1211-related deaths. However, there were 10 deaths in total, with 
4 animals sacrificed in moribund condition with eye-related changes, 3 were 
due to gavage errors (2 were sacrificed moribund, 1 was found dead), and the 
cause of 3 deaths was not determined (1 was sacrificed moribund due to 
clinical observations and 2 were found dead). Additional details for these 
deaths can be found in the IB6 (Section 4.3.2.1.2). No GB1211-related, adverse 
effects were observed (no effects on clinical signs, ophthalmic observations, 
body weights, food consumption, clinical pathology parameters, organ weight, 
or macroscopic or microscopic pathology were observed in the dosing or 
recovery periods). The no observed adverse effect level (NOAEL) was 
500 mg/kg/day, which corresponded to maximum observed plasma 
concentration (Cmax) values of 17005.0 and 22506.6 ng/mL, and area under the 
plasma concentration-time curve (AUC) from zero to the time of the last 
quantifiable concentration (AUC0-tlast) values of 46617.4 and 
58355.9 ng·h/mL, for males and females, respectively, on Day 42 (Table 1).

• In 2 dog repeat-dose toxicity studies, systemic saturation was observed at doses 
> 50 mg/kg. No GB1211-related adverse effects were observed. Increases in QT and 
QT interval corrected for heart rate (QTc) intervals noted in males at 15 or 
50 mg/kg/day and females at 50 mg/kg/day were not considered adverse because the 
range of individual QT values were within what would be considered the normal 
range for the dog. The left bundle branch block (LBBB) noted in one female at 
50 mg/kg/day (1 hour postdose in Week 6) is not a normal variation in dogs, however, 
as it was present during the predose phase collection for this animal, it was not 
considered to be GB1211 related (Covance study 8377741 – to be published). In 
addition, no electrocardiogram (ECG) findings were observed in telemeterized dogs 
given up to 50 mg/kg in the cardiovascular safety pharmacology study. The NOAEL 
was 50 mg/kg/day, which corresponded to Cmax values of 27047.0 and 
17789.9 ng/mL, and AUC0-tlast values of 117585.2 and 63452.2 ng·h/mL, for males 
and females, respectively, on Day 42 (Table 2). 
In addition, there was no genotoxic potential for GB1211 in appropriately conducted assays 
in bacteria (reverse mutation test), human lymphocytes (in vitro micronucleus test), and in 
mouse bone marrow (in vivo micronucleus test).  
No developmental and reproductive toxicology studies have been conducted so far. 
1.5. 
Summary of Nonclinical Pharmacokinetics 
In the 6-week GLP study6 in CD-1 mice (doses of 50, 150, and 500 mg/kg/day; Table 1) Cmax 
values were reached between 15 minutes and 2 hours. Apparent plasma terminal half-life 
(t1/2) values ranged between 1.93 and 3.63 hours. In general, increases in AUC0-tlast on Day 1 
and Day 42 were less than dose-proportional between 50 and 500 mg/kg, with AUC0-tlast 
being higher at 150 mg/kg/day than at 500 mg/kg/day on Day 42 for both male and females.   
The Cmax and AUC0-tlast values on Day 42 decreased after daily administration. No sex 
differences were observed.

In the 6-week study in Beagle dogs6 (doses of 5, 15, and 50 mg/kg/day; Table 2) Cmax values 
were reached between 0.5 and 1.02 hours. Values for t1/2 ranged between 4.47 and 8.23 hours. 
In general, increases in AUC0-tlast values on Day 1 and Day 42 were approximately 
dose-proportional between 5 and 15 mg/kg and were less than dose-proportional between 15 
and 50 mg/kg. Mean Cmax and AUC0-tlast values were similar between Day 1 and Day 42, 
suggesting no accumulation. Concentrations were generally higher for males when compared 
to females.

a The no observed adverse effect level 
In 5 pharmacokinetic (PK) studies, effects of GB1211 on human ATP binding cassette 
transporters, single-dose absorption, tissue distribution, and elimination, protein binding, in 
vitro metabolism, and enzyme inhibition were evaluated. Results indicated that GB1211 is a

substrate of P-glycoprotein (P-gp), but not of breast cancer resistance protein (BCRP); and an 
inhibitor of BCRP, but not of P-gp. The mean free fractions of GB1211 in plasma were 
14.1% (rabbit), 7.66% (mouse), 5.34% (human), 3.87% (dog), 1.22% (rat); and protein 
binding was not concentration dependent. Mean elimination half-lives from plasma were 1.46 
(intravenous) and 3.04 hours (oral), with total plasma exposure (AUC0-tlast) to 
[14C]-GB1211-related radioactivity at 1170 (intravenous) and 13100 h.ng eq./g (oral). Oral 
bioavailability was 109%. In albino and pigmented mice, [14C]-GB1211-related radioactivity 
was well absorbed and rapidly distributed into tissues, [14C]-GB1211-related radioactivity 
was rapidly eliminated from tissues, and the mean overall recovery of the radioactivity 
administered was 103%. GB1211 showed a trend for distribution to the uveal tract and skin 
of pigmented mice. This was reversible and below the limit of quantification at 168 hours. 
(refer to Sections 4.2.3 and 4.2.5 of IB6 for further information). The mean free fractions of 
GB1211 in human liver microsomes across GB1211 concentrations were similar at protein 
concentrations of 0.1 mg/mL (97.8%) and 1 mg/mL (67.6%), but at 5 mg/mL the free fraction 
was higher at 1 µM (61.5%) than at 10 μM (26.4%) and 100 μM (36.4%). The metabolic 
turnover (percent of parent remaining) of [14C]-GB1211 was most extensive in dog, mouse, 
and rat hepatocytes; was lower in rabbit; and was negligible in human hepatocytes. No 
unique human in vitro metabolites were formed and the proportions of metabolites present in 
the human profiles were not greater than those observed in the other species. Enzyme 
activities mediated by cytochrome P450 (CYP)-1A2, CYP2C8, CYP2D6 and CYP3A4 were 
weakly inhibited by GB1211, and the inhibition was not considered to be metabolism 
dependent.  
Further details from the nonclinical PK programme can be found in the IB.6  
1.6. 
Summary of Clinical Experience 
This study is a first-in-human study. No clinical studies have been performed with GB1211 to 
date. 
1.7. 
Study Rationale 
The principal aim of this study is to obtain safety and tolerability data when GB1211 is 
administered orally as single doses and as multiple doses to healthy subjects. In addition, an 
optional part has been included to obtain safety and tolerability data when GB1211 is 
administered orally as multiple doses to subjects with suspected NASH and liver fibrosis 
(refer to Section 3.1). This information, together with the PK data, will help establish the 
doses and dosing regimen suitable for future studies in subjects with the targeted indication. 
The effect of GB1211 on exploratory biomarkers will also be investigated, along with the 
effects of food on the PK of GB1211. 
1.8. 
Benefit-risk Assessment 
Healthy subjects and subjects with suspected NASH and liver fibrosis in the current study 
will not receive any health benefit (beyond that of an assessment of their medical status) from 
participating in the study. The risks of participation are primarily those associated with 
adverse reactions to the investigational medicinal product (IMP), although there may also be 
some discomfort from collection of blood samples and other study procedures. More

3. INVESTIGATIONAL PLAN 
This is a Phase 1, randomised, double-blind, placebo-controlled, first-in-human study in 
which the safety, tolerability, and PK of orally administered GB1211 will be assessed in 
healthy adult subjects and adult subjects with suspected NASH and liver fibrosis.  
Suspected NASH is defined as the presence or history of fatty liver, together with elevated 
alanine aminotransferase (ALT; defined as ALT values ≥ 30 U/L in males or ≥ 20 U/L in 
females), plus either confirmed type 2 diabetes mellitus (T2DM) or metabolic syndrome 
(Adult Treatment Panel III definition), in the absence of any other liver disease. Additional 
criteria aim to enrich for individuals with liver fibrosis (as per inclusion criteria; Section 4.3). 
The study will consist of 3 parts: a SAD phase (Part A) enrolling a total of 5 cohorts of 
healthy subjects; a MAD phase (Part B) enrolling 2 cohorts of healthy subjects; and an 
optional Part C MAD phase, enrolling 1 cohort of subjects with suspected NASH and liver 
fibrosis. One cohort of Part A will receive GB1211 under both fasted and fed conditions to 
investigate the effect of food.  
3.1. 
Overall Study Design and Plan 
3.1.1. 
Part A 
Part A will comprise a single-dose, sequential-cohort study incorporating a single-cohort, 
randomised, 2-part arm to investigate the effect of food. Overall, 40 subjects will be studied 
in 5 cohorts (Cohort A1 to A5), with each cohort consisting of 8 subjects.

Potential subjects will be screened to assess their eligibility to enter the study within 28 days 
prior to the first dose administration. Each subject will participate in 1 treatment period only, 
residing at the Clinical Research Unit (CRU) from Day -1 (the day before dosing) to Day 3 
(48 hours postdose), except for the food-effect cohort (planned to be Cohort A3), where each 
subject will participate in 2 treatment periods separated by a minimum of 7 days.  
All subjects will return for a Follow-up visit 5 to 7 days after their final dose.  
Dose Regimen: 
In each of Cohorts A1 to A5, 6 subjects will receive GB1211 and 2 will receive placebo. In 
all cohorts, except the food-effect cohort, all doses will be administered in the fasted state in 
accordance with a randomisation schedule on the morning of Day 1. For the food-effect 
cohort, which is planned to be Cohort A3, Treatment Period 1, Day 1 doses will be 
administered in the fasted state in accordance with the randomisation schedule and in 
Treatment Period 2, Day 1 doses will be given 30 minutes after the start of a high fat 
breakfast. Each subject in Cohorts A1 to A5 (except the food-effect cohort) will receive only 
a single dose of GB1211 or placebo during the study. In the food-effect cohort, subjects will 
receive the same treatment in both periods and will receive 2 single doses of GB1211 or 
placebo during the study. 
In Cohorts A1 to A5 (except the fed period of the food-effect cohort), dosing will occur such 
that 2 subjects (1 active and 1 placebo) will be dosed at least 24 hours before the remaining 
subjects, where continuation to dose the remaining subjects will be at the Investigator’s 
discretion. 
Based on the ongoing review of the safety, tolerability, and PK results, additional 
nonresidential visits may be required. The number of additional visits per subject will not 
exceed 3 and will not extend beyond 28 days after each final dosing occasion. 
An overview of the study design is shown in Figure 1 and Figure 2 and the planned dose

Part B will start following review of safety, tolerability, and PK data from a single dose with 
exposure higher than the predicted steady-state exposure. 
Potential subjects will be screened to assess their eligibility to enter the study within 28 days 
prior to the first dose administration. Each subject will participate in 1 treatment period only 
and reside at the CRU from Day -1 (the day before dosing) until the morning of Day 11 
(24 hours after the final dose on Day 10). 
All subjects will return for a Follow-up visit 5 to 7 days after their final dose.  
Dose Regimen: 
In each of Cohorts B1 to B2, 8 subjects will receive GB1211 and 3 subjects will receive 
placebo. The dietary state for dosing in Part B will be fasted unless data from the food-effect 
cohort is available and supports dosing in the fed state. For all subjects, the planned dosing 
will be BID on Days 1 to 9, inclusive, and a final single dose administration will occur in the 
morning of Day 10. The dosing interval/frequency and dosing duration in Part B may be 
changed following review of data from cohorts in Part A (Section 3.4). The predicted total 
daily exposure will not exceed the highest exposure observed in Part A. There will be a 
minimum of 10 days between dose escalations for each cohort. 
An overview of the study design is shown in Figure 4 and the planned dose levels in Figure 5.

Part C (Optional) 
Part C will comprise a multiple-dose cohort of 25 subjects with suspected NASH and liver 
fibrosis (Cohort C1). Part C may start following review of data from Part A and at least 
1 Part B cohort. 
Potential subjects will be screened to assess their eligibility to enter the study within 28 days 
prior to the first dose administration. Each subject will participate in 1 treatment period only 
and reside at the CRU from Day -1 (the day before dosing) until the morning of Day 2, 
returning for nonresidential visits on Days 7, 14, 21, 28, and 35. Subjects will then check 
back into the CRU on Day 41 until the morning of Day 43 (24 hours after the final dose on 
Day 42). 
All subjects will return for a Follow-up visit 5 to 7 days after their final dose. 
Dose Regimen: 
For Part C, Cohort C1, 15 subjects will receive GB1211 and 10 subjects will receive placebo. 
The dietary state for dosing in Part C will be fasted unless data from the food-effect cohort is 
available and supports dosing in the fed state. For all subjects, the planned dosing will be BID 
on Days 1 to 41 inclusive, and a final single dose administration will occur in the morning of 
Day 42. The total daily dose administered, dose interval/frequency, and dosing duration will 
be based on review of data from Parts A and B.

 Study Start and End of Study Definitions 
The start of the study is defined as the date the first subject, who is subsequently enrolled, 
signs an Informed Consent Form (ICF). The point of enrolment occurs at the time of subject 
number allocation. The end of the study is defined as the date of the last subject’s last 
assessment (scheduled or unscheduled). 
3.3. 
Additional Groups 
Following review of the safety, tolerability, and PK data, additional dose cohorts (where 
systemic exposure is not expected to exceed that stated in the dose escalation stopping criteria 
[Section 3.7]) may be added to the study. Up to 3 further cohorts may be included in each of 
Parts A, B, and C. The requirement for additional cohorts will be agreed with the Sponsor 
and documented in the Trial Master File (TMF). 
3.4. 
Discussion of Study Design, Including the Choice of Control Groups 
For Parts A and B of the study, a sequential-cohort, ascending-dose design has been chosen 
for safety reasons as GB1211 is in the early stages of clinical development, with Part A of the 
study being the first time it will be administered to humans. Oral doses have been chosen for 
all parts of the study, as this is the intended clinical route of administration. A 2-part design 
has been chosen for the food-effect arm, as this gives a within-subject assessment of the 
influence of food on the PK of GB1211 and so increases the power of the study for the given 
number of subjects.

Page 30 of 78 
It is the intent of Part B to dose subjects such that steady-state plasma levels of GB1211 are 
achieved and maintained for several days. Based on the available nonclinical data, it is 
expected that this will be achieved following 9 days of BID dosing; however, a full review of 
all the safety, tolerability, and PK data from Part A will be performed to confirm the dose 
regimen for Part B. The dose regimen will comprise no less than once every day and will not 
exceed 4-times-daily dosing. The dosing duration will comprise no fewer than 7 consecutive 
days and will not exceed 14 consecutive days of dosing.  
Conducting the initial single- and MAD in healthy subjects mitigates the potential 
confounding effects of the disease state and concomitant medications.  
For Part C, it is the intent to dose subjects with suspected NASH and liver fibrosis to 
investigate safety, tolerability, PK, and the effect on specified exploratory biomarkers 
following multiple oral doses of GB1211 in subjects of the targeted indication. Preclinical 
toxicology data provides evidence for dosing over 42 days for Part C, and a study by 
Mudaliar et al., indicates that decreases in serum markers of fibrosis were observed following 
6 weeks administration of obeticholic acid in NAFLD patients7; however, a full review of all 
the safety, tolerability, PK, and emerging exploratory biomarker data from Parts A and B will 
be performed to confirm the dose regimen for Part C. 
Details of the dosing regimen and duration used for Parts B and C of the study will be 
documented in the TMF. 
Based upon the nonclinical data, the duration of each treatment period is considered adequate 
to achieve the study objectives. Where applicable, an interval of at least 7 days between 
treatment periods in the food-effect arm is considered adequate to prevent carryover of 
GB1211; however, may be adjusted based on emerging PK data. 
This study will be double-blind and placebo-controlled in order to avoid bias in the collection 
and evaluation of data during its conduct. Placebo has been chosen as the control treatment to 
assess whether any observed effects are treatment-related or simply reflect the study 
conditions. 
Continuous 12-lead ECG monitoring will be included in this study in order to explore 
potential GB1211 effects on the QT interval, with a view of supporting a potential thorough 
QT study waiver. 
3.4.1. 
Dose Interval 
Following thorough review of all available nonclinical data (pharmacological and 
toxicological), dosing at each dose level in Part A will be such that 2 subjects (1 GB1211 and 
1 placebo) will be dosed 24 hours before the remaining 6 subjects. After dosing the first 
2 subjects on a separate day, a minimum of a 5-minute dosing interval for the remaining 
6 subjects in each dose-ascending cohort is considered acceptable. Continuation to dose the 
remaining 6 subjects will be at the Investigator’s discretion.  
For Part B, sentinel dosing is not planned as the total daily dose administered will not exceed 
a dose shown to be safe and well tolerated in Part A. In addition, accumulation is not 
expected based on the available nonclinical data and therefore, predicted total daily exposure

in Part B will not exceed a well-tolerated exposure in Part A. However, following review of 
data in Part A, sentinel dosing may be introduced for Part B cohorts, if exposure is predicted 
to exceed the maximum exposure in Part A. 
3.5. 
Selection of Doses in the Study 
In the 42-day repeat oral dose toxicology studies, NOAELs in the mouse and the dog were 
500 mg/kg/day and 50 mg/kg, respectively, corresponding to human equivalent doses (HEDs) 
of 40 and 27 mg/kg, respectively. Therefore applying a 10-fold safety margin the maximum 
recommended starting dose (MRSD) is 2.7 mg/kg, approximately 162 mg for a 60 kg subject. 
In vitro data in human cells suggests an IC50 of GB1211 of 0.1 µM (0.5 µg/mL) supporting 
the chosen MRSD. 
In the PD study6 evaluating the effect of GB1211 in carbon tetrachloride-induced liver 
fibrosis in mice there was no pharmacological activity observed at 2 mg/kg but there was 
activity at 10 mg/kg. Therefore the MRSD that is not considered to be pharmacologically 
active, based on the 2 mg/kg dose level, is 0.16 mg/kg, equivalent to approximately 9.6 mg in 
a 60 kg subject. The lowest pharmacologically active dose has been defined as 10 mg/kg, 
representing a HED of 48 mg for a 60 kg subject. 
The proposed starting dose of 5 mg is 1.9-fold lower than the MRSD of 9.6 mg (based on the 
PD study6) and therefore is not expected to have any pharmacological activity.  
The proposed IMP dose levels for the study are shown in Table 3. As described in Section 3.6 
each dose following the starting dose may be subject to change based on review of data from 
previous cohorts.

For Part C of the study, dose levels, dosing frequency/interval, and dosing duration will be 
fully decided, in consultation with the Sponsor, on the basis of data from Part A, and at least 
1 Part B cohort. The total daily dose of GB1211 administered during this part of the study 
will not exceed the maximum well-tolerated dose level studied in Part A.

Dose levels should not increase by more than 5-fold for predicted nonpharmacologically 
active dose levels and by 3-fold for predicted pharmacologically active dose levels.  
The highest dose level may exceed the top dose shown in the above table, providing systemic 
exposure does not exceed that stated in the dose escalation stopping criteria (Section 3.7). 
Details of all doses administered in Parts A, B, and C of the study will be documented in the 
TMF. 
3.6. 
Dose Escalation 
Doses will be administered in an escalating manner following satisfactory review by the 
Sponsor and Investigator of the safety and tolerability data (up to 48 hours post-final dose) 
and PK data (up to 24 hours post-final dose) from the lower dose levels. Doses may be 
reduced and may be lower than the starting dose. There will be a minimum of 10 days 
between dose escalations to allow sufficient time for an adequate safety review. 
Dose escalation in both Parts A and B will only occur if data from a minimum of 6 and 
7 subjects, respectively, have been reviewed from the previous lower dose cohort, such that 
data from a minimum of 4 subjects who have received GB1211 will be used to make the dose 
escalation decision. 
The justification for this is as follows: 
• Based upon nonclinical data, no clinically important off-target effects are 
expected within the proposed dose range. 
• A minimum of 4 subjects receiving the active drug is considered sufficient to 
characterise the safety profile and PK response to GB1211. 
Between each dose escalation, the Investigator will review all available blinded data to ensure 
it is safe to proceed with the planned dose escalation. An interim safety report, summarising 
results from all available safety assessments, will be sent to the Sponsor prior to the start of 
each successive cohort. Any clinically significant results will be discussed with the Sponsor 
before dose escalation continues. Interim PK data will also be reviewed in terms of dose 
escalation and to confirm that the study design remains appropriate. In the event of a 
disagreement between Sponsor and Investigator on the dose escalation decision, the decision 
of the Investigator will be upheld. 
3.7. 
Dose Escalation Stopping Criteria 
The study will be halted if 1 or more subjects experience an serious adverse event (SAE) that 
is considered to be related to IMP or 2 or more subjects experience severe AEs that are 
considered to be related to IMP. If, following an internal safety review, the Sponsor deems it 
appropriate to restart the study; this can be done following approval of a substantial protocol 
amendment.

In Parts A and B, following consultation with the Sponsor, dose escalation will stop if: 
• One or more subjects in a cohort experience an SAE that is considered to be 
related to IMP or 2 or more subjects in a cohort experience severe AEs that are 
considered to be related to IMP. 
• Clinically relevant signs or symptoms of similar nature occur in 2 or more 
subjects in a cohort that, in the opinion of the Investigator, warrant stopping of 
dose escalation. 
• There is evidence of clinically significant increases in liver function tests 
(aspartate aminotransferase [AST], ALT, alkaline phosphatase, bilirubin, and/or 
gamma-glutamyl transferase), defined as 3 times the upper limit of normal (ULN) 
in 2 or more subjects in a cohort (confirmed with repeat testing), which are 
considered related to the IMP in the opinion of the Investigator. 
• QT interval corrected for heart rate using Fridericia’s method (QTcF) 
increases > 60 msec compared to baseline (predose) and/or absolute QTcF 
values > 500 msec (confirmed by repeat measurement) in 2 or more subjects in a 
cohort. 
• The systemic exposure for any individual subject is predicted to exceed a Cmax of 
19755 ng/mL and/or an AUC from time zero to 24 hours postdose (AUC0-24) of 
52486 ng.h/mL; ie, systemic exposure will be no greater than the lowest exposure 
at the NOAEL (Criterion is based on preclinical toxicology data from both male 
and female mice, where no gender differences were observed in terms of safety 
findings).

For Parts A and B, subjects may previously have been screened on a generic basis to 
determine their eligibility for inclusion in Phase I clinical studies conducted at the CRU. If 
generic screening was performed within the specified study screening window, selected 
study-specific procedures will be repeated either at an additional Screening visit or on 
admission to the CRU on Day -1.  
4.7. 
Subject Number and Identification 
Subjects will have a unique identification number used at Screening. Subjects will be 
assigned a subject number at the time of first dose/dosing. Assignment of subject numbers 
will be in ascending order and no numbers will be omitted (eg, in Part A Subjects 0101, 0102, 
etc, in Part B Subjects 0201, 0202, etc, in Part C Subjects 0301, 0302, etc). Replacement 
subjects (Section 4.8) will be assigned a subject number corresponding to the number of the 
subject he/she is replacing plus 1000 (eg, Subject 1101 replaces Subject 101). 
Subjects will be identified by subject number only on all study documentation. A list 
identifying the subjects by subject number will be kept in the Site Master File. 
4.8. 
Subject Withdrawal and Replacement 
A subject is free to withdraw from the study at any time. In addition, a subject will be 
withdrawn if any of the following criteria are met: 
• change in compliance with any inclusion/exclusion criterion that is clinically 
relevant and affects subject safety as determined by the Investigator (or designee). 
• noncompliance with the study restrictions that might affect subject safety or study 
assessments/objectives, as considered applicable by the Investigator (or designee). 
• any clinically relevant sign or symptom that, in the opinion of the Investigator (or 
designee), warrants subject withdrawal. 
In the event of confirmed results for any of the following criteria, dosing of a subject with the 
IMP will be stopped permanently: 
• 
QTcF increases > 60 msec compared to baseline (predose) and/or absolute 
QTcF values > 500 msec (confirmed by repeat measurement). 
• 
Systemic exposure for any individual subject is predicted to exceed a Cmax of 
19755 ng/mL and/or an AUC0-24 of 52486 ng.h/mL; ie, systemic exposure will 
be no greater than the lowest exposure at the NOAEL.  
• 
Liver chemistry results: 
1. ALT or AST > 5 x ULN, which is confirmed by repeat 
2. ALT or AST >  3 x ULN, which is confirmed and total bilirubin > 2 x 
ULN or international normalised ratio >1.5 
3. ALT or AST > 3 x ULN, which is confirmed and the new appearance 
(ie, onset coincides with the changes in hepatic enzymes) of fatigue, 
nausea, vomiting, right upper quadrant pain or tenderness, fever, rash,

or eosinophilia (> ULN) felt by the Investigator to be potentially 
related to hepatic inflammation/injury. 
If a subject is withdrawn, the Sponsor will be notified and the date and reason(s) for the 
withdrawal will be documented in the subject’s electronic Case Report Form (eCRF). If a 
subject is withdrawn, efforts will be made to perform all follow-up assessments, if possible 
(Appendix 6). Other procedures may be performed at the Investigator’s (or designee’s) and/or 
Sponsor’s discretion. If the subject is in-house, these procedures should be performed before 
the subject is discharged from the clinic. The Investigator (or designee) may also request that 
the subject return for an additional Follow-up visit. All withdrawn subjects will be followed 
until resolution of all their AEs or until the unresolved AEs are judged by the Investigator (or 
designee) to have stabilised. 
Subjects who are withdrawn for reasons not related to study drug may be replaced following 
discussion between the Investigator and the Sponsor. Subjects withdrawn as a result of AEs 
thought to be related to the study drug will generally not be replaced. 
4.9. 
Study Termination 
The study may be discontinued at the discretion of the Investigator (or designee), Sponsor, or 
Sponsor’s Medical Monitor if any of the following criteria are met: 
• adverse events unknown to date (ie, not previously reported in any similar 
investigational study drug trial with respect to their nature, severity, and/or 
duration). 
• increased frequency, severity, and/or duration of known, anticipated, or previously 
reported AEs (this may also apply to AEs defined at Check-in as baseline signs 
and symptoms). 
• medical or ethical reasons affecting the continued performance of the study. 
• difficulties in the recruitment of subjects. 
• cancellation of drug development. 
5. STUDY TREATMENTS 
5.1. 
Description, Storage, Packaging, and Labelling 
The IMPs (5 and 50 mg GB1211 and placebo capsules) will be supplied by the Sponsor (or 
designee), along with the batch/lot numbers and Certificates of Analysis. A Certificate of 
Release authorised by a Qualified Person in the EU will also be issued for the IMP. 
The IMP will be provided in high-density polyethylene bottles and stored according to the 
instructions on the label. The IMPs will be stored at the study site in a location that is locked 
with restricted access. 
The bulk drug container and unit dose containers will be labelled in accordance with national 
laws and regulations. The IMPs will be transferred from bulk supplies into the subject’s dose 
container by qualified clinical staff.

Study Treatment Administration 
Each dose of GB1211 and placebo will be administered orally with approximately 240 mL of 
room temperature water. In Part A, all doses will be administered after an overnight fast of at 
least 10 hours, with the exception of the food-effect cohort (planned to be Cohort A3), where 
the dose given in Treatment Period 2 will be administered 30 minutes after starting a high-fat 
breakfast. The dietary status for dosing in Parts B and C will be fasted unless data from the 
food-effect cohort is available and supports dosing in the fed state. 
Subjects in Part A and B will be administered the IMP in numerical order while standing and 
will not be permitted to lie supine for 2 hours after dosing, except as necessitated by the 
occurrence of an AE(s) and/or study procedures.  
In Part C, the doses of GB1211 (taken at the site) on Days 1/2 and Days 41/42 will be 
administered to subjects at the study site while standing and will not be permitted to lie 
supine for 2 hours after dosing, except as necessitated by occurrence of an AE(s) and/or study 
procedures; but all other doses will be administered by the subject at home. 
5.3. 
Randomisation 
For Parts A and B, the randomisation code will be produced by the statistics department at 
Covance using a computer-generated pseudo-random permutation procedure. Randomisation 
for Part C is to be confirmed. 
In Part A, 2 subjects per cohort will be randomly assigned to receive placebo. For all cohorts 
in Part A (except the fed treatment period of the food-effect cohort), sentinel dosing will 
occur whereby 2 subjects (1 active and 1 placebo) will be dosed on 1 day and, providing no 
safety concerns arise, the remaining 6 subjects will be dosed after 24 hours.  
Subjects in the food-effect cohort (planned to be Cohort A3) will be randomised to receive 
the same treatment in Treatment Periods 1 and 2.  
In Part B, 3 subjects per cohort will be randomly assigned to receive placebo, and in Part C, 
10 subjects in Cohort C1 will be randomly assigned to receive placebo.

Prior to the start of the study, live randomisation code will be distributed according to the 
randomisation specification form and will include the Covance CRU pharmacy staff.  
5.4. 
Blinding 
The following controls will be employed to maintain the double-blind status of the study: 
• The placebo capsules will be identical in appearance to the GB1211. 
• The Investigator and other members of staff involved with the study will remain 
blinded to the treatment randomisation code during the assembly procedure. 
• Interim bioanalytical data will be provided to Covance in a blinded manner. 
• Where possible, exploratory biomarker data will be provided to Covance in a 
blinded manner. 
To maintain the blind, the Investigator will be provided with a sealed randomisation code for 
each subject, containing details of their treatment. These individual sealed envelopes will be 
kept in a limited access area that is accessible 24 hours a day. In order to manage subject 
safety or to support dose escalation decisions (in the event of possibly treatment-related SAEs 
or severe AEs), the decision to unblind resides solely with the Investigator. Whenever 
possible, and providing it does not interfere with or delay any decision in the best interest of 
the subject, the Investigator will discuss the intended code-break with the Sponsor. If it 
becomes necessary to break the code during the study, the date, time, and reason will be 
recorded in the subject’s source data and on the individual envelope and will be witnessed by 
a second person. 
5.5. 
Treatment Compliance 
The following measures will be employed to ensure treatment compliance for Parts A and B: 
• All doses will be administered under the supervision of suitably qualified study 
site staff. 
• Immediately after dose administration, visual inspection of the mouth and hands 
will be performed for each subject. 
• At each dosing occasion, a predose and postdose inventory of IMP will be 
performed on the dose containers. 
For Part C, treatment compliance will be assessed based on the number of capsules provided 
on Day 1 compared to the number of capsules returned on Day 42. 
5.6. 
Drug Accountability 
The Investigator (or designee) will maintain an accurate record of the receipt of the study 
supplies received. In addition, an accurate drug disposition record will be kept, specifying the 
amount dispensed to each subject and the date of dispensing. This drug accountability record 
will be available for inspection at any time. At the completion of the study, the original drug 
accountability record will be available for review by the Sponsor upon request.

For each batch of unit doses, the empty used unit dose containers will be discarded upon 
satisfactory completion of the compliance and accountability procedures. Any unused 
assembled unit doses will be retained until completion of the study. 
At the completion of the study, all unused supplies will be returned to the Sponsor or 
disposed of by the study site, per the Sponsor’s written instructions.

Concomitant Therapies for Part C 
Subjects of Part C will refrain from use of any prescription or nonprescription 
medications/products during the study with exceptions, as stated in Section 4.6, until the 
Follow-up visit, unless the Investigator (or designee) and/or Sponsor have given their prior 
consent.  
Paracetamol/acetaminophen (2 g/day for up to 3 consecutive days) and hormone replacement 
therapy are acceptable concomitant medications.  
The administration of any other concomitant medications during the study is prohibited 
without prior approval of the Investigator (or designee), unless its use is deemed necessary 
for treatment of an AE. Any medication taken by a subject during the course of the study and 
the reason for its use will be documented in the source data. 
6.2. 
Diet 
6.2.1. 
Parts A and B 
While confined at the study site for Parts A and B, subjects will receive a standardised diet at 
scheduled times that do not conflict with other study-related activities. Subjects will be fasted 
overnight (at least 8 hours) before collection of blood samples for clinical laboratory

On the days with intensive PK assessments (Day 1 for Part A and Days 1 and 10 for Part B), 
meals will be identical for each cohort, with the exception of the high-fat breakfast for the 
food-effect cohort (planned to be Cohort A3). 
On Day 1 in Part A, subjects will be fasted for at least 10 hours prior to study drug 
administration until 4 hours postdose, when a meal will be provided (lunch times on Day 1 
will be staggered between subjects to ensure this). With the exception of water given with the 
dose, subjects will not be allowed fluids from 1 hour prior to until 2 hours after dosing. Meals 
will be provided as appropriate at other times. Other than the fluid restrictions on dosing 
days, water will be freely available at all times. 
For the food-effect cohort (planned to be Cohort A3), subjects receiving the GB1211 or 
placebo under fed conditions will consume the following high-fat breakfast (Table 5) before 
dosing. Subjects should start the meal 30 minutes prior to administration of the IMP. Study 
subjects should eat this meal in 30 minutes or less. The drug product should be administered 
30 minutes after start of the meal.

activities. Subjects will be fasted overnight (at least 8 hours) before collection of blood 
samples for safety laboratory tests.  
On the days with intensive PK assessments (Days 1 and 42), every effort will be made to 
ensure within a subject that they have the same meal on these PK assessment days. 
The time interval between meals and dosing will be determined by the PK data from Part A 
and will be documented in the TMF. During the residential or nonresidential visits, meals will 
be provided as appropriate at other times. With the exception of water given with the dose, 
subjects will not be allowed fluids from 1 hour prior to dosing until 2 hours after dosing. 
Other than these fluid restrictions, water will be freely available at all times. 
From 7 days prior to Check-in until the Follow-up visit, foods and beverages containing 
poppy seeds, grapefruit, or Seville oranges will not be allowed. Caffeine-containing foods 
and beverages will not be allowed from 36 hours before each site visit.  
Consumption of alcohol will not be permitted from 36 hours prior to each site visit. During 
the rest of study, the patient should limit alcohol consumption to 2 units per day. 
6.3. 
Smoking 
For Parts A and B, subjects will not be permitted to use tobacco- or nicotine-containing 
products within 3 months prior to Check-in until the Follow-up visit. 
6.4. 
Exercise 
Subjects are required to refrain from strenuous exercise from 7 days before Check-in until the 
Follow-up visit and will otherwise maintain their normal level of physical activity during this 
time (ie, will not begin a new exercise program nor participate in any unusually strenuous 
physical exertion). 
6.5. 
Blood Donation 
Subjects are required to refrain from donation of blood from 3 months prior to Screening, 
plasma from 2 weeks prior to Screening, and platelets from 6 weeks prior to Screening until 
3 months after the Follow-up visit.  
6.6. 
Exposure to Ultraviolet Light 
Subjects should minimise or avoid exposure to natural or artificial sunlight (tanning beds or 
UVA/B treatment) following administration of study drug until 24 hours after the last dose. If 
subjects need to be outdoors during this period, they should wear loose fitting clothes that 
protect skin from sun exposure and discuss other sun protection measures with the 
Investigator.

7. STUDY ASSESSMENTS AND PROCEDURES 
Every effort will be made to schedule and perform the procedures as closely as possible to the 
nominal time, giving considerations to appropriate posture conditions, practical restrictions, 
and the other procedures to be performed at the same timepoint. 
The highest priority procedures will be performed closest to the nominal time. The order of 
priority for scheduling procedures around a timepoint is (in descending order of priority): 
• dosing 
• blood samples 
• urine samples (Part A only) (for GB1211 assay) 
• any other procedures (ECGs will be scheduled before vital signs measurements). 
Where activities at a given timepoint coincide, consideration must be given to ensure that the 
following order of activities is maintained: ECGs, vital signs, blood draws. 
7.1. 
Pharmacokinetic Assessments 
7.1.1. 
Sample Collection and Processing 
Blood samples (approximately 1 × 4 mL) will be collected by venipuncture or cannulation at 
the times indicated in the Schedule of Assessments in Appendix 6. Furthermore, up to 
3 additional blood samples may be taken from each subject per treatment period, with the 
maximum volume of blood withdrawn per subject not exceeding the limit detailed in 
Appendix 3. Any changes to the scheduled times of PK assessments will be agreed with the 
Sponsor and documented in the TMF. Samples taken from subjects who received placebo 
will not be analysed. 
Procedures for collection, processing, and shipping of PK blood samples will be detailed in a 
separate document.  
Urine samples for Part A will be collected into preweighed polyethylene containers over the 
time intervals indicated in the Schedule of Assessments in Appendix 6. Procedures for 
collection, processing, and shipping of PK urine samples will be detailed in a separate 
document. 
7.1.2. 
Analytical Methodology 
Plasma and urine concentrations of GB1211 will be determined using validated analytical 
procedures. Specifics of the analytical methods will be provided in separate documents. 
An exploratory analysis of GB1211 metabolites in plasma and urine may be performed 
utilising the blood and urine samples collected for PK evaluation. If performed, the results of 
this analysis will be reported separately to the clinical study report.

7.2. 
Exploratory Biomarker Assessments 
Biomarkers (as listed in Section 2.2.3) in which to assess the exploratory objectives include: 
• Serum galectin-3 
• CCL4 
• Fasting plasma glucose and insulin 
• Lipid profile (eg, low density lipoprotein [LDL], high density lipoprotein [HDL], 
total cholesterol, triglycerides) 
• hsCRP, IL-12, MCP1, and TNF-α, as well as the proinflammatory chemokines, 
CCL2, CCL3, CCL4, and the chemokine receptors CCR1 and CCR2; and other 
biomarkers of inflammation as required 
• Exploratory biomarkers related to fibrosis will include but are not limited to 
extracellular matrix proteins (TIMP-1, HA, and P3NP), A9, ELF panel, CK18, 
PAI-1, CH3L1, IL6, and pro-collagen 3  
The list of biomarkers for the exploratory endpoints may be subject to change based on 
ongoing review of the data. 
The timings of all exploratory biomarker assessments to be performed (as described in 
Section 2.2.3) during the study are indicated in the Schedule of Assessments in Appendix 6 
and may be subject to change based on the ongoing review of the data.  
Blood samples for these assessments will be collected by venipuncture or cannulation, with 
blood volumes including 3 additional blood samples if required (each subject per treatment 
period) detailed in Appendix 3. To avoid potential issues with repeat freeze thawing, samples 
of serum will be aliquoted into a minimum of 2 but ideally 3 aliquots. Samples for biomarker 
analysis will be shipped to an alternate site (to be determined) for analysis, and may be kept 
for future analysis of other exploratory biomarkers. 
Any changes to the scheduled times of biomarker assessments will be agreed with the 
Sponsor and documented in the TMF. 
7.3. 
Safety and Tolerability Assessments 
Additional safety and tolerability assessments as described below will be performed at other 
times if judged to be clinically appropriate or if the ongoing review of the data suggests a 
more detailed assessment of clinical laboratory safety evaluations is required. 
7.3.1. 
Adverse Events 
Adverse event definitions, assignment of severity and causality, and procedures for reporting 
SAEs are detailed in Appendix 1. 
The condition of each subject will be monitored from the time of signing the ICF to final 
Discharge from the study. Subjects will be observed for any signs or symptoms and asked 
about their condition by open questioning, such as “How have you been feeling since you

were last asked?”, at least once each day while resident at the study site and at each study 
visit. Subjects will also be encouraged to spontaneously report AEs occurring at any other 
time during the study. 
Any AEs and remedial action required will be recorded in the subject’s source data. The 
nature, time of onset, duration, and severity will be documented, together with an 
Investigator’s (or designee’s) opinion of the relationship to study drug. 
Adverse events recorded during the course of the study will be followed up, where possible, 
until resolution or until the unresolved AEs are judged by the Investigator (or designee) to 
have stabilised. This will be completed at the Investigator’s (or designee’s) discretion. 
7.3.2. 
Clinical Laboratory Evaluations 
Blood and urine samples will be collected for clinical laboratory evaluations (including 
clinical chemistry, haematology, urinalysis, serology [including coagulation parameters for 
Part C]) at the times indicated in the Schedule of Assessments in Appendix 6. Clinical 
laboratory evaluations are listed in Appendix 2. Additional clinical laboratory evaluations 
will be performed at other times if judged to be clinically appropriate or if the ongoing review 
of the data suggests a more detailed assessment of clinical laboratory safety evaluations is 
required. 
Subjects will be asked to provide urine samples for drugs of abuse screen and will undergo an 
alcohol breath test at the times indicated in the Schedule of Assessments in Appendix 6. For 
all female subjects, a pregnancy test will be performed at the times indicated in the Schedule 
of Assessments in Appendix 6.  
An Investigator (or designee) will perform a clinical assessment of all clinical laboratory 
data. 
7.3.3. 
Vital Signs 
Supine blood pressure, supine pulse rate, and oral body temperature will be assessed at the 
times indicated in the Schedule of Assessments in Appendix 6. Vital signs may also be 
performed at other times if judged to be clinically appropriate or if the ongoing review of the 
data suggests a more detailed assessment of vital signs is required. 
Day 1 predose blood pressure and pulse rate will be measured in triplicate at approximately 
2-minute intervals. The median value will be used as the baseline value in the data analysis. 
All subsequent measurements will be performed singly and repeated once if outside the 
relevant clinical reference ranges. Oral body temperature will be measured singly. 
Subjects must be supine for at least 5 minutes before blood pressure and pulse rate 
measurements.

7.3.4. 
Electrocardiogram 
7.3.4.1. 
12-Lead Electrocardiogram 
Resting 12-lead ECGs will be recorded after the subject has been supine and at rest for at 
least 5 minutes at the times indicated in the Schedule of Assessments in Appendix 6. Single 
12-lead ECGs will be repeated once if either of the following criteria apply: 
• QTcF value > 500 msec 
• QTcF change from the baseline (predose) is > 60 msec. 
Additional 12-lead ECGs may be performed at other times if judged to be clinically 
appropriate or if the ongoing review of the data suggests a more detailed assessment of ECGs 
is required. The Investigator (or designee) will perform a clinical assessment of each 12-lead 
ECG.  
Day 1 predose 12-lead ECGs will be measured in triplicate at approximately 2-minute 
intervals. The mean value will be used as the baseline value in the data analysis. All 
subsequent measurements will be performed singly and repeated once if outside the relevant 
clinical reference ranges. 
7.3.4.2. 
Telemetry 
Cardiac rhythm will be monitored by telemetry at the times indicated in the Schedule of 
Assessments in Appendix 6. 
Telemetry is not planned for Parts B and C of the study but may be implemented if any 
clinically significant findings are identified in the data from Part A. 
7.3.4.3. 
Continuous 12-lead Electrocardiogram Monitoring for Part A 
Continuous 12-lead ECG monitoring using a digital recorder will take place at the times 
indicated in the Schedule of Assessments in Appendix 6. Continuous 12-lead ECG 
monitoring will not be performed in the fed treatment period in Part A. 
All continuous ECG data collected on study will be archived without extraction or analysis 
and will not be reported in the scope of this study. 
Subjects will be supine for at least 10 minutes before the extraction timepoint and for 
5 minutes from the start of each extraction timepoint (each extraction will last for 5 minutes). 
Environmental distractions (eg, television, radio, conversation) should be avoided during the 
pre-ECG resting period and during ECG recording.  
When coinciding, vital signs assessments and PK sampling should always be performed after 
the ECG extraction time window. If a separate ECG machine is being used for safety 
assessments described in Section 7.3.4.1, that machine should be in place prior to the 
extraction window to permit safety ECGs to be recorded irrespective of the extraction 
window. If the machine is not in place prior to the extraction window, safety ECGs must be

recorded after the extraction window. If an integral system is used, safety ECGs may be 
recorded irrespective of the extraction window. 
7.3.5. 
Physical Examination 
A full physical examination or symptom-directed physical examination will be performed at 
the timepoints specified in the Schedule of Assessments in Appendix 6. Full physical 
examination will usually only be performed at Screening. 
7.3.6. 
Body Weight 
Body weight (in underclothes) will be recorded at the times indicated in the Schedule of 
Assessments in Appendix 6. 
8. SAMPLE SIZE AND DATA ANALYSIS 
8.1. 
Determination of Sample Size 
No formal statistical assessment, in terms of sample size, has been conducted as this is the 
first time GB1211 is being administered to humans. However, the number of subjects in each 
part of the present study is common in early clinical pharmacology studies and is considered 
sufficient to achieve the objectives of the study. 
8.2. 
Analysis Populations 
8.2.1. 
Safety Population 
The safety population will include all subjects who received at least 1 dose of study treatment 
(GB1211 or placebo). 
8.2.2. 
Pharmacokinetic Population 
The PK population will include all subjects who received at least 1 dose of GB1211 and have 
evaluable PK data. A subject will be excluded from the PK summary statistics and statistical 
analysis if the subject has an AE of vomiting that occurs at or before 2-times median time to 
maximum concentration.  
8.2.3. 
Biomarker Population 
The biomarker population will include all subjects who received at least 1 dose of study 
treatment (GB1211 or placebo) and have at least 1 postdose biomarker assessment. 
8.3. 
Pharmacokinetic Analyses 
Noncompartmental PK analysis will be performed on individual plasma and urine (Part A 
only for urine) concentration data, using commercial software such as Phoenix® WinNonlin®.  
Plasma and urine concentrations (Part A only for urine) of GB1211 and PK parameters will 
be listed and summarised using descriptive statistics. Individual and mean GB1211 
concentration-time profiles will also be presented graphically.

In Part A, where data are available, GB1211 dose proportionality will be examined across 
dose cohorts. The PK parameters will be analysed for dose proportionality using a power 
model approach or analysis of variance (ANOVA) model as appropriate. Where data are 
available, the effect of food at 1 dose level in Part A will be investigated using ANOVA. 
In Part B, the PK parameters on Day 10 will be analysed for dose proportionality using a 
power model approach or ANOVA model as appropriate. 
8.4. 
Exploratory Biomarker Analyses 
Exploratory biomarker data will be listed and summarised using descriptive statistics. No 
formal statistical analysis of exploratory biomarker data is planned. 
8.5. 
Safety Analysis 
Safety parameters will be listed and summarised using descriptive statistics. No formal 
statistical analysis of safety data is planned. Each AE will be coded using the Medical 
Dictionary for Regulatory Activities. 
8.6. 
Interim Analysis 
No formal interim analyses are planned for this study.

Appendix 1: Adverse Event Reporting 
Definitions 
An adverse event (AE) is any untoward medical occurrence in a patient or clinical 
investigation subject administered a pharmaceutical product, which does not necessarily have 
a causal relationship with this treatment. An AE can therefore be any unfavourable and/or 
unintended sign (including a clinically significant abnormal laboratory finding), symptom, or 
disease temporally associated with the use of a study drug, whether or not related to the study 
drug. 
Assessment of Severity 
The Investigator will be asked to provide an assessment of the severity of the AE using the 
following categories:  
• Mild: Usually transient and may require only minimal treatment or therapeutic 
intervention. The event does not generally interfere with usual activities of daily 
living. 
• Moderate: Usually alleviated with additional specific therapeutic intervention. 
The event interferes with usual activities of daily living, causing discomfort but 
poses no significant or permanent risk of harm to the subject. 
• Severe: Interrupts usual activities of daily living, or significantly affects clinical 
status, or may require intensive therapeutic intervention. 
Relationship to Study Treatment 
The Investigator (or designee) will make a determination of the relationship of the AE to the 
study drug using a 4-category system according to the following guidelines: 
• Not Related: The AE is definitely caused by the subject’s clinical state or the 
study procedure/conditions. 
• Unlikely Related: The temporal association between the AE and the drug is such 
that the drug is not likely to have any reasonable association with the AE. 
• Possibly Related: The AE follows a reasonable temporal sequence from the time 
of drug administration but could have been produced by the subject’s clinical state 
or the study procedures/conditions. 
• Related: The AE follows a reasonable temporal sequence from administration of 
the drug, abates upon discontinuation of the drug, follows a known or 
hypothesised cause-effect relationship, and (if appropriate) reappears when the 
drug is reintroduced.  
Follow-up of Adverse Events 
Every reasonable effort will be made to follow up with subjects who have AEs. Any subject 
who has an ongoing AE that is possibly related or related to the investigational medicinal

Page 56 of 78 
product (IMP) or study procedures at the Follow-up visit will be followed up, where possible, 
until resolution or until the unresolved AE is judged by the Investigator (or designee) to have 
stabilised. This will be completed at the Investigator’s (or designee’s) discretion. Any subject 
who has an ongoing AE that is not related or unlikely related to the IMP or study procedures 
at the Follow-up visit can be closed out as ongoing at the Investigator’s discretion.  
Adverse Drug Reactions 
All noxious and unintended responses to an IMP (ie, where a causal relationship between an 
IMP and an AE is at least a reasonable possibility) related to any dose should be considered 
adverse drug reactions. 
For marketed medicinal products, a response to a drug which is noxious and unintended and 
which occurs at doses normally used in man for prophylaxis, diagnosis, or therapy of diseases 
or for modification of physiological function is to be considered an adverse drug reaction. 
An unexpected adverse drug reaction is defined as an adverse reaction, the nature or severity 
of which is not consistent with the applicable product information (eg, Investigator’s 
Brochure for an unapproved IMP). 
Serious Adverse Events 
A serious AE (SAE) is defined as any untoward medical occurrence that at any dose either: 
• results in death 
• is life-threatening 
• requires inpatient hospitalisation or prolongation of existing hospitalisation 
• results in persistent or significant disability/incapacity (disability is defined as a 
substantial disruption of a person’s ability to conduct normal life functions) 
• results in a congenital anomaly/birth defect 
• results in an important medical event (see below). 
Important medical events that may not result in death, be life-threatening, or require 
hospitalisation may be considered SAEs when, based upon appropriate medical judgment, 
they may jeopardise the subject and may require medical or surgical intervention to prevent 
one of the outcomes listed in this definition. 
Instances of death or congenital abnormality, if brought to the attention of the Investigator at 
any time after cessation of the study treatment and considered by the Investigator to be 
possibly related to the study treatment, will be reported to the Sponsor. 
Definition of Life-threatening 
An AE is life-threatening if the subject was at immediate risk of death from the event as it 
occurred (ie, does not include a reaction that might have caused death if it had occurred in a 
more serious form). For instance, drug-induced hepatitis that resolved without evidence of

Protocol Reference: GB1211-001 
Protocol Version 2.0, 05 November 2018 
Page 57 of 78 
hepatic failure would not be considered life-threatening even though drug-induced hepatitis 
can be fatal. 
Definition of Hospitalisation 
Adverse events requiring hospitalisation should be considered serious. In general, 
hospitalisation signifies that the subject has been detained (usually involving an overnight 
stay) at the hospital or emergency ward for observation and/or treatment that would not have 
been appropriate at the Clinical Research Unit (CRU). When in doubt as to whether 
hospitalisation occurred or was necessary, the AE should be considered as serious. 
Hospitalisation for elective surgery or routine clinical procedures, which are not the result of 
an AE, need not be considered AEs and should be recorded on a Clinical Assessment Form 
and added to the electronic Case Report Form. If anything untoward is reported during the 
procedure, this must be reported as an AE and either ‘serious’ or ‘nonserious’ attributed 
according to the usual criteria. 
Serious Adverse Event Reporting 
Covance Drug Safety Solutions (DSS) are responsible for coordinating the reporting of SAEs 
in accordance with the European Directive 2001/20/EC. 
The Investigator will complete an SAE report form and forward it by facsimile or email to 
DSS and the Sponsor immediately (within 24 hours) upon becoming aware of an SAE. 
The responsibilities of Covance DSS include the following: 
• Prepare an AE reporting plan prior to the start of the study. Where this plan differs 
from the applicable CRU standard operating procedure on SAE reporting, the 
Safety Management Plan will always take precedence. 
• Receive and review SAE report forms from the CRU and inform the Sponsor of 
the SAE within 2 working days of the initial notification to DSS. Drug Safety 
Services will delete any information from the SAE report forms that may identify 
the subject. 
• Write case narratives and enter the case into Covance’s safety database as defined 
in the AE reporting plan. 
• Produce appropriate reports of all Suspected Unexpected Serious Adverse 
Reactions and forward to the Ethics Committee, Medicines and Healthcare 
Products Regulatory Agency, Principal Investigator, and the Sponsor within the 
timeframes stipulated in the Clinical Trials Directive Guideline (ENTR/CT 3).  
The responsibility for reporting SAEs will be transferred to the Sponsor 28 days after the end 
of the study.

Pregnancy 
Pregnancy (maternal or paternal exposure to study drug) does not meet the definition of an 
AE. However, to fulfil regulatory requirements any pregnancy should be reported following 
the SAE process to collect data on the outcome for both mother and foetus.

Appendix 4: Contraception Guidance 
Definitions 
Women of Childbearing Potential: premenopausal females who are anatomically and 
physiologically capable of becoming pregnant following menarche. 
Women of Nonchildbearing Potential:  
1. Surgically sterile: females who are permanently sterile via hysterectomy, 
bilateral salpingectomy, and/or bilateral oophorectomy by reported medical 
history and/or medical records. Surgical sterilisation to have occurred a minimum 
of 6 weeks, or at the Investigator’s discretion, prior to Screening. 
2. Postmenopausal: Females at least 45 years of age with amenorrhea for 12 months 
without an alternative medical reason with confirmatory follicle-stimulating 
hormone (FSH) levels of ≥ 40 mIU/mL. The amenorrhea should not be induced by 
a medical condition such as anorexia nervosa, hypothyroid disease or polycystic 
ovarian disease, or by extreme exercise. It should not be due to concomitant 
medications that may have induced the amenorrhea such as oral contraceptives,

Contraception Guidance 
Female Subjects 
Female subjects who are of nonchildbearing potential will not be required to use 
contraception.  
Female subjects of childbearing potential must be willing to use 2 methods (1 primary and 
1 secondary method) of birth control from the time of signing the Informed Consent Form 
until 90 days after the Follow-up visit. Primary (non-barrier) methods of contraception 
include: 
• hormonal injection (as prescribed) 
• combined oral contraceptive pill or progestin/progestogen-only pill (as prescribed) 
• combined hormonal patch (as prescribed) 
• combined hormonal vaginal ring (as prescribed) 
• surgical method performed at least 3 months prior to the Screening visit: 
o 
bilateral tubal ligation 
o 
Essure® (hysteroscopic bilateral tubal occlusion) with confirmation of 
occlusion of the fallopian tubes

• hormonal implant 
• hormonal or non-hormonal intrauterine device 
• vasectomised male partner (sterilisation performed at least 90 days prior to the 
Screening visit, with verbal confirmation of surgical success, and the sole partner 
for the female subject)  
Secondary (barrier) methods of contraception include: 
• male condom with spermicide 
• female condom with spermicide 
• over-the-counter sponge with spermicide 
• cervical cap with spermicide (as prescribed) 
• diaphragm with spermicide (as prescribed). 
Female subjects of childbearing potential should refrain from donation of ova from Check-in 
(Day -1) until 90 days after the Follow-up visit. 
Male Subjects 
Male subjects (even with a history of vasectomy) with partners of childbearing potential must 
use a male barrier method of contraception (ie, male condom with spermicide) in addition to 
a second method of acceptable contraception from Check-in until 90 days after the Follow-up 
visit. Acceptable methods of contraception for female partners include: 
• hormonal injection 
• combined oral contraceptive pill or progestin/progestogen-only pill 
• combined hormonal patch 
• combined hormonal vaginal ring 
• surgical method (bilateral tubal ligation or Essure® [hysteroscopic bilateral tubal 
occlusion])  
• hormonal implant 
• hormonal or non-hormonal intrauterine device 
• over-the-counter sponge with spermicide 
• cervical cap with spermicide 
• diaphragm with spermicide 
An acceptable second method of contraception for male subjects is vasectomy that has been 
performed at least 90 days prior to the Screening visit, with verbal confirmation of surgical 
success.

For male subjects (even with a history of vasectomy), sexual intercourse with female partners 
who are pregnant or breastfeeding should be avoided unless condoms are used from the time 
of the first dose until 90 days after the Follow-up visit. Male subjects are required to refrain 
from donation of sperm from Check-in until 90 days after the Follow-up visit. 
Sexual Abstinence and Same-sex Relationships 
For subjects who practice true abstinence, subjects must be abstinent for at least 6 months 
prior to Screening and must agree to remain abstinent from the time of signing the ICF until 
90 days after the Follow-up visit. 
A subject in a same-sex relationship at the time of signing the ICF must agree to refrain from 
engaging in a heterosexual relationship from the time of signing the ICF until 90 days after 
the Follow-up visit.

Appendix 5: Regulatory, Ethical, and Study Oversight Considerations 
Regulatory and Ethical Considerations 
This study will be conducted in accordance with the protocol and with the following: 
• Consensus ethical principles derived from international guidelines including the 
Declaration of Helsinki and Council for International Organizations of Medical 
Sciences (CIOMS) International Ethical Guidelines. 
• Applicable International Conference on Harmonisation (ICH) Good Clinical 
Practice (GCP) Guidelines. 
• Applicable laws and regulations. 
The protocol, protocol amendments, Informed Consent Form (ICF), Investigator Brochure, 
and other relevant documents must be submitted to an Ethics Committee (EC) by the 
Investigator and reviewed and approved by the EC before the study is initiated.  
Any substantial protocol amendments, likely to affect the safety of the subjects or the conduct 
of the study, will require EC and regulatory authority (as locally required) approval before 
implementation of changes made to the study design, except for changes necessary to 
eliminate an immediate hazard to study subjects or any nonsubstantial changes, as defined by 
regulatory requirements.  
The Investigator will be responsible for the following: 
• Providing written summaries of the status of the study to the EC annually or more 
frequently in accordance with the requirements, policies, and procedures 
established by the EC. 
• Notifying the EC of serious adverse events or other significant safety findings as 
required by EC procedures. 
• Providing oversight of the conduct of the study at the site and adherence to 
requirements of 21 Code of Federal Regulations (CFR), ICH guidelines, the EC, 
European regulation 536/2014 for clinical studies (if applicable), and all other 
applicable local regulations. 
Finances and Insurance 
Financing and insurance will be addressed in a separate agreement. 
Informed Consent 
Prior to starting participation in the study, each subject will be provided with a study-specific 
ICF giving details of the study drugs, procedures, and potential risks of the study. Subjects 
will be instructed that they are free to obtain further information from the Investigator (or 
designee) and that their participation is voluntary and they are free to withdraw from the 
study at any time. Subjects will be given an opportunity to ask questions about the study prior 
to providing consent for participation.

Covance Study: 8392356 
Protocol Reference: GB1211-001 
Protocol Version 2.0, 05 November 2018 
Page 67 of 78 
Following discussion of the study with Clinical Research Unit personnel, subjects will sign 
2 copies of the ICF in the presence of a suitably trained member of staff to indicate that they 
are freely giving their informed consent. One copy will be given to the subject, and the other 
will be maintained in the subject’s records. 
Subjects must be re-consented to the most current version of the ICF(s) during their 
participation in the study. 
Subject Data Protection 
Subjects will be assigned a unique identifier and will not be identified by name in electronic 
Case Report Forms (eCRFs), study-related forms, study reports, or any related publications. 
Subject and Investigator personal data will be treated in compliance with all applicable laws 
and regulations. In the event the study protocol, study report, or study data are included in a 
public registry, all identifiable information from individual subjects or Investigators will be 
redacted according to applicable laws and regulations.  
The subject must be informed that his/her personal study-related data will be used by the 
Sponsor in accordance with local data protection law. The level of disclosure must also be 
explained to the subject. The subject must also be informed that his/her study-related data 
may be examined by Sponsor or Contract Research Organisation (CRO) auditors or other 
authorised personnel appointed by the Sponsor, by appropriate EC members, and by 
inspectors from regulatory authorities. 
Disclosure 
All information provided regarding the study, as well as all information collected and/or 
documented during the course of the study, will be regarded as confidential. The Investigator 
(or designee) agrees not to disclose such information in any way without prior written 
permission from the Sponsor. 
Data Quality Assurance 
The following data quality steps will be implemented: 
• All relevant subject data relating to the study will be recorded on eCRFs unless 
directly transmitted to the Sponsor or designee electronically (eg, laboratory data). 
The Investigator is responsible for verifying that data entries are accurate and 
correct by electronically signing the eCRF.  
• The Investigator must maintain accurate documentation (source data) that 
supports the information entered in the eCRF.  
• The Investigator must permit study-related monitoring, audits, EC review, and 
regulatory agency inspections and provide direct access to source data documents.  
• Covance is responsible for the data management of this study including quality 
checking of the data. Predefined agreed risks, monitoring thresholds, quality 
tolerance thresholds, controls, and mitigation plans will be documented in a risk

management register. Additional details of quality checking to be performed on 
the data may be included in a Data Management Plan.  
• A Study Monitor will perform ongoing source data verification to confirm that 
data entered into the eCRF by authorised site personnel are accurate, complete, 
and verifiable from source documents; that the safety and rights of subjects are 
being protected; and that the study is being conducted in accordance with the 
currently approved protocol and any other study agreements, ICH GCP, and all 
applicable regulatory requirements. 
• Records and documents, including signed ICFs, pertaining to the conduct of this 
study must be retained by the Investigator in the study site archive for at least 
5 years after the end of the study unless local regulations or institutional policies 
require a longer retention period. No records may be destroyed during the 
retention period without the written approval of the Sponsor. No records may be 
transferred to another location or party without written notification to the Sponsor.  
Investigator Documentation Responsibilities 
All individual, subject-specific study data will also be entered into a 21 CFR 
Part 11-compliant electronic data capture (EDC) system on an eCRF in a timely fashion. 
All data generated from external sources (eg, laboratory and bioanalytical data), and 
transmitted to Covance electronically, will be integrated with the subject’s eCRF data in 
accordance with the Data Management Plan.  
An eCRF must be completed for each enrolled subject who undergoes any screening 
procedures, according to the eCRF completion instructions. The Sponsor, or CRO, will 
review the supporting source documentation against the data entered into the eCRFs to verify 
the accuracy of the electronic data. The Investigator will ensure that corrections are made to 
the eCRFs and that data queries are resolved in a timely fashion by the study staff. 
The Investigator will sign and date the eCRF via the EDC system’s electronic signature 
procedure. These signatures will indicate that the Investigator reviewed and approved the 
data on the eCRF, data queries, and site notifications. 
Publications 
If on completion of the study the data warrant publication, the Investigator may publish the 
results in recognised (refereed) scientific journals subject to the provisions of the clinical 
study agreement (CSA). Unless otherwise specified in the CSA, the following process will 
occur: 
If the Investigator expects to participate in the publication of data generated from this site, the 
institution and Investigator will submit reports, abstracts, manuscripts, and/or other 
presentation materials to the Sponsor for review before submission for publication or 
presentation. The Sponsor will have 60 days to respond with any requested revisions 
including, without limitation, the deletion of confidential information. The Investigator will 
act in good faith upon requested revisions, except the Investigator will delete any confidential
