PROTOCOL SUMMARY 
1.1. 
Synopsis 
Protocol Title: A single centre, single dose, open-label, randomised, 2-way crossover 
study in healthy Japanese male subjects to evaluate the bioequivalence of daprodustat 
tablets (2 mg tablet vs. 4 mg tablet) (Part 1) and the food effect on the pharmacokinetics 
of daprodustat (Part 2). 
Short Title: Daprodustat bioequivalence and food effect study 
Rationale: 
This study is composed of two parts. Part 1 aims to evaluate the bioequivalence of 
daprodustat tablets (2 mg tablet vs. 4 mg tablet), and Part 2 aims to evaluate the food 
effect on the pharmacokinetics (PK) of daprodustat. 
Objectives and Endpoints: 
Objective 
Endpoint 
Primary 
Part 1 
• To determine the bioequivalence of 
daprodustat 2 mg tablet vs. 4 mg tablet in 
healthy Japanese male subjects. 
Part 2 
• To investigate the food effect on PK of 
daprodustat following a single dose of 
daprodustat in the fed and fasted state in 
healthy Japanese male subjects. 
Parts 1 and 2 
• Plasma PK parameters for daprodustat: 
AUC(0-t), Cmax, and the other 
parameters [AUC(0-inf), Tmax, 
t1/2, %AUCex, CL/F, Vz/F, kel and MRT] 
Secondary 
Parts 1 and 2 
• To assess the safety and tolerability of 
single dose of daprodustat following 
administration of daprodustat in healthy 
Japanese male subjects. 
Parts 1 and 2 
• Safety: Adverse events (AEs), clinical 
laboratory tests, vital signs (blood 
pressure, pulse and body temperature), 
and 12-lead electrocardiogram (ECG) 
parameters. 
 
Overall Design: 
This study consists of two parts; Part 1 is a single centre, single dose, open-label, 
randomised, 2-way crossover study in healthy Japanese male subjects. Part 2 is a single

centre, single dose in the fed and fasted state, open-label, randomised, 2-way crossover 
study in healthy Japanese male subjects.  
In both parts (Part 1 and Part 2), healthy subjects will have a screening visit within 30 
days prior to the first dose of study intervention, two intervention periods, and re-visit 7 
(±1) days after the second dose for follow-up. All subjects will be administered 
daprodustat as a single oral dose, with assessments conducted for up to 24 hours post-
dose. Subjects will be housed in the clinical research unit from Day -1 through Day 2 of 
each period. At least 5-day wash-out period will occur between each intervention period. 
Disclosure Statement: This is an open-label, 2 parts, 2-way crossover study. 
Number of Participants: 
Sufficient participants will be randomised such that approximately 52 and 12 (a total of 
64 participants) evaluable participants complete the study of Part 1 and Part 2, 
respectively. The definition of the study complete is described in the section 4.4. 
If participants prematurely discontinue the study, additional replacement participants may 
be recruited and assigned to the same treatment sequence at the discretion of the Sponsor 
in consultation with the investigator. 
If PK parameters are not within the bioequivalence acceptance criterion because of an 
insufficient number of participants, one add-on participant study can be performed using 
not less than half the number of participants with the same methodology as the initial 
study according to the “Guideline for bioequivalence studies for different strengths of 
oral solid dosage forms [MHLW, 2012]” (Japanese BE guideline). 
Intervention Groups and Duration: 
Subjects will be divided into the study of Parts 1 and 2, and will be randomized to one of 
two groups (Part 1: A or B, Part 2: C or D) in the following table;  
Part 1 (Bioequivalence part) 
• Daprodustat 2 mg tablet x 2, single dose, in the fasted state

• 
The timing and number of planned study assessments, including safety, or PK assessments may be altered during the course of 
the study based on newly available data (e.g. to obtain data closer to the time of peak plasma concentrations) to ensure 
appropriate monitoring.  
• 
Any changes in the timing or addition of time points for any planned study assessments as the result of emerging PK data from 
this study must be documented and approved by the relevant study team member and then archived in the sponsor and site study 
files, but will not constitute a protocol amendment. The Institutional Review Board (IRB) will be informed of any safety issues 
that constitute a substantial amendment and require alteration of the safety monitoring scheme or amendment of the informed 
consent form (ICF). The changes will be approved by the IRB before implementation.

2. 
INTRODUCTION 
Daprodustat (GSK1278863) is a prolyl hydroxylase inhibitor that stimulates 
erythropoiesis in a manner similar to the natural response to hypoxia, whereby inhibition 
of hypoxia inducible factor (HIF) prolyl-4-hydroxylases (PHD1, PHD2, PHD3) by 
daprodustat ultimately results in increased levels of HIF-responsive genes. Daprodustat is 
currently under development in oral dose as an emerging new class of agent for treatment 
of anaemia associated with chronic kidney disease (CKD). 
2.1. 
Study Rationale 
Daprodustat is formulated as immediate release tablets with dose strengths of 1 mg, 2 mg, 
4 mg and 6 mg. For the commercial formulation coloured film coats will be used for the 
1 mg, 2 mg and 6 mg tablets and white film coat will be remained for 4 mg tablet for the 
Japanese market. The dissolution profiles of these tablets have been evaluated according 
to the Japanese BE guideline, and the dissolution test results across strengths 
demonstrated equivalence with the exception of the 2 mg vs 4 mg test using water. The 
result of the 2 mg vs 4 mg dissolution test using water was considered due to properties 
of the drug substance and the drug products of daprodustat. Considering the 
administration manner for the renal anaemia patients in Japan, the risk that water has any 
effects following administration of daprodustat in humans is low. This study is planned 
according to Japanese Guideline as follows: 
Part 1 
The purpose of Part 1 is to evaluate the bioequivalence between daprodustat tablet 
strengths (2 mg vs. 4 mg) in healthy Japanese male subjects according to the Japanese BE 
guideline. 
Part 2 
The purpose of Part 2 is to evaluate the food effect on the PK of daprodustat in healthy 
Japanese male subjects with reference to Japanese Notification for Clinical 
Pharmacokinetic Studies of Pharmaceuticals [MHLW, 2001]. This part will assess the PK 
of a single oral dose of daprodustat under fasted state and following a standard meal with 
reference to the Dietary recommendations for chronic kidney disease in Japan [Jpn J 
Nephrol, 2014]. 
2.2. 
Background 
As of June 2017, more than 1700 patients and healthy subjects have received daprodustat 
in domestic and overseas clinical trials. For Japanese subjects, a global Phase I study 
including 19 Japanese subjects (dose: 10 - 100 mg single dose) and three Phase II studies 
which are domestic and multinational (dose: up to 12 mg daily including 163 Japanese 
patients) have completed, and three Phase III studies (dose: 1 - 24 mg daily) are ongoing. 
Administration of daprodustat in development with a high fat/calorie breakfast led to a 
1.0 hr delay in Tmax and 29% decrease in Cmax, and an 8% decrease in AUC in healthy

South Asian subjects resident in India (Study PHI113634). These data suggest that 
daprodustat may be administered without regard to food. 
A detailed description of the chemistry, pharmacology, efficacy, and safety of 
daprodustat is provided in the Investigator’s Brochure (IB). 
2.3. 
Benefit/Risk Assessment 
Summaries of findings from both clinical and non-clinical studies conducted with 
daprodustat can be found in the daprodustat IB and IB supplement(s), if applicable.

2.3.1. 
Risk Assessment 
The potential risks of clinical significance including adverse events of special interest (AESI)(Section 8.3.4), and the mitigation strategies 
for this protocol taking into account the results of completed clinical and non-clinical studies with daprodustat, are outlined in the table 
below. These sentences are included in the interests of transparency. However, the risks of following events after the single lower dose 
(up to 4 mg) administration in this study are considered very low. 
Potential Risk of Clinical Significance 
Summary of Data/Rationale for Risk 
Mitigation Strategy 
Investigational Product (IP) [Daprodustat] 
Excessive erythropoiesis (polycythaemia) 
leading to thrombosis and/or tissue ischaemia 
In animal studies, excessive erythropoiesis (haemoglobin (Hgb) 
/haematocrit (Hct) > upper limit normal) attributed to daprodustat was 
associated with vascular congestion, inflammation, microthrombi, and 
tissue ischaemia in a number of organs. 
Phase II dose-ranging studies, and associated statistical and dose 
response modelling has informed Phase III dose rationale, starting doses, 
dose steps, and dose adjustment scheme to optimize Hgb management. 
Following review of clinical data received to date, this has not been 
identified as a safety concern for daprodustat at clinically relevant doses. 
 
Specific eligibility criteria related to 
requirements for entry Hgb are detailed in 
Exclusion Criteria. 
 
Hgb will be closely monitored throughout the 
dosing period as outlined in the SoA (Section 
1.2). 
 
Specific guidance for discontinuation of 
daprodustat based on Hgb is provided in 
Section 7.1. 
 
Monitoring of emerging safety data by an 
internal GSK Safety Review Team. 
Death, Myocardial infarction (MI), stroke, heart 
failure, thromboembolic events, thrombosis of 
vascular access at Hgb levels which are within 
the normal range (i.e. not polycythaemic 
conditions) 
Marketed recombinant human erythropoietin (rhEPO) and its analogues 
have been associated with an increased risk for death and serious 
cardiovascular (CV) events when used in patients with anaemia of CKD. 
In non-clinical studies conducted to date, not observed at tolerated doses 
when Hgb/Hct within normal range for species. 
The clinical data received to date are insufficient to conclude or refute this 
risk. 
 
Specific eligibility criteria related to CV risk are 
outlined in Section 5.2. 
 
Hgb will be closely monitored throughout the 
dosing period as outlined in the SoA (Section 
1.2).  
 
Monitoring of emerging safety data by an 
internal GSK Safety Review Team. 
Oesophageal and gastric erosions (e.g. upper 
gastrointestinal (GI) bleeding, severe abdominal 
pain, upper GI perforations)  
In animal studies, undesirable GI effects including emesis, abnormal 
faeces and/or decreased food consumption/body weight loss and stomach 
erosions/ulcers with haemorrhage were observed with daprodustat. 
In rats, stomach erosions were observed with intravenous and oral 
administration of daprodustat. 
Stomach erosions/ulcers also reported in rats with some marketed rhEPO 
 
Suspected GI bleeding or significant symptoms 
consistent with erosions or ulcers should be 
investigated diagnostically (i.e. endoscopic 
examination) as clinically warranted. 
 
Monitoring of emerging safety data by an 
internal GSK Safety Review Team.

Potential Risk of Clinical Significance 
Summary of Data/Rationale for Risk 
Mitigation Strategy 
and its analogues. 
In clinical trials to date with daprodustat, mild-moderate GI signs and 
symptoms represent the most frequently reported AE, however causal 
association has not been established. 
Following review of clinical data received to date, GI erosions have not 
been identified as a safety concern for daprodustat. 
Cancer-related mortality and tumour progression 
and recurrence 
In clinical trials, use of rhEPO and its analogues in patients with cancer has 
been associated with increased risk of cancer related morbidity and 
mortality. 
Administration of 60 mg/kg daprodustat to mice caused minimal increases 
in circulating vascular endothelial growth factor (VEGF) while significant 
erythropoietin (EPO) increases were observed. There were no test article-
related neoplastic findings in 2-year rat (oral daprodustat) or mouse 
(daprodustat + subcutaneous injection of the 3 major human metabolites; 
M2, M3 and M13) carcinogenicity studies. 
In clinical studies conducted to date, administration of daprodustat has 
been associated with: 
Once daily administration: 
 
In studies up to 4 weeks duration, a dose-ordered increase in VEGF 
plasma concentrations was observed at doses ranging from 10 to 
150 mg. In studies up to 24 weeks duration at doses up to 25 mg, 
changes in VEGF plasma concentrations were variable but similar 
relative to control. 
 
Systemic EPO concentrations within the physiologic range. 
Three times weekly administration: 
In studies up to 4 weeks duration at doses of 10 to 30 mg: 
 
Dose dependent increases in plasma VEGF and EPO concentrations 
were observed. 
 
Pre-dose concentrations of EPO and VEGF were near or below 
baseline indicating no accumulation of EPO or VEGF after three 
times weekly dosing. 
Following review of clinical data received to date, this has not been 
identified as a safety concern for daprodustat.  


Potential Risk of Clinical Significance 
Summary of Data/Rationale for Risk 
Mitigation Strategy 
suggested based on well-established effects of acute and chronic hypoxia 
in man on the pulmonary vasculature (vasoconstriction), and by findings in 
patients with naturally occurring mutations that result in decreased HIF 
degradation [Smith, 2006; Formenti, 2011]. 
There have been no histopathologic findings suggestive of PAH in pre-
clinical safety studies (up to 13-weeks duration in dogs, up to 2-years in 
rats and mice, and up to 39-weeks in monkeys.) 
Acute hypoxic challenge (rats): Daprodustat produced increases in peak 
right ventricular pressure (PRVP) during acute hypoxia that were slightly 
higher than the vehicle control group. However, these hypoxia-induced 
PRVP changes were within the range of PRVP changes noted among 
untreated rats. 
Results from a clinical study of acute hypoxic challenge in patients 
demonstrated that short-term (5 days) therapy with daprodustat 5 mg or 
100 mg had no clinically significant effect on transthoracic 
echocardiographic estimates of pulmonary artery systolic pressure (PASP) 
under either normoxic or hypoxic conditions. 
Echocardiograph (ECHO) assessments performed in Phase IIb studies 
(24weeks treatment duration) did not identify any clinically meaningful 
changes in PASP in subjects not on dialysis. 
In haemodialysis subjects, mean absolute change from baseline in PASP 
was similar for both treatment groups; however, there was a numeric 
imbalance (GSK Total: 8 [7%]; Control 0) in subjects reaching the PASP 
potential clinical importance (PCI) (>20 mmHg increase from baseline). 
Regarding this imbalance, there were a number of confounding factors in 
the study, most notably a 4.5:1 randomization scheme and inconsistency in 
timing of ECHOs relative to dialysis day. 
Additionally, 2 of 3 subjects with resolution of PASP on safety follow-up 
ECHOs had confounding conditions that could contribute to resolution 
other than discontinuation of study drug; and there was no dose 
relationship for subjects meeting the PASP PCI criterion. Overall, there is 
insufficient evidence to conclude a relationship to treatment with 
daprodustat.

identified as a safety concern for daprodustat. 
Cardiomyopathy 
Published data suggest that cardiac effects of HIF stabilization are likely a 
function of the mechanism, extent, and duration of the effects, and can 
range from protective to detrimental depending upon the specific model 
and experimental conditions utilized. 
With lifetime exposure to daprodustat in a 2-year rat oral carcinogenicity 
study, an exacerbation of rat spontaneous, progressive cardiomyopathy 
(PCM)(focal myofiber degeneration/necrosis with inflammatory infiltrates) 
was observed at doses of 0.8 mg/kg/day and above, although total 
incidence and severity distribution within any daprodustat group were 
within historical control ranges. This is consistent with an equivocal 
threshold for exacerbation of spontaneous, PCM at 0.8 mg/kg/day which is 
also the threshold dose for observing increased Hct values in individual 
rats. 
Cardiomyopathy has not been associated with naturally occurring mutation 
in man which results in increased HIF stabilization. 
ECHO assessments performed in Phase IIb studies (24 weeks treatment 
duration) did not identify any clinically meaningful changes in left 
ventricular ejection fraction (LVEF). 
Following review of clinical data received to date, this has not been 
identified as a safety concern for daprodustat.

Proliferative retinopathy, macular oedema,

Increases in local (ocular) VEGF production with retinal neovascularization 
and macular oedema observed in diabetic retinopathy and to choroidal 
leakage, oedema and neovascularization seen in age-related macular 
degeneration [Campochiaro, 2006]. 
Administration of 60 mg/kg daprodustat to mice caused minimal increases 
in circulating VEGF while significant EPO increases were observed. 
Aside from congestion of retinal vessels and optic disc hyperaemia 
secondary to markedly increased red cell mass, no ocular abnormalities 
were observed in non-clinical studies. 
In clinical studies up to 4 weeks duration, a dose-ordered increase in 
VEGF plasma concentrations was observed at doses ranging from 10 to 
150 mg administered once daily and from 10 to 30 mg administered three 
times weekly.

Summary of Data/Rationale for Risk

In studies up to 24 weeks duration at doses up to 25 mg, changes in VEGF 
plasma concentrations were variable but similar relative to control. 
Ophthalmologic assessments performed in Phase IIb studies (24 weeks 
treatment duration) did not identify any clinically meaningful changes in 
proliferative retinopathy, macular oedema, or choroidal neovascularization. 
Following review of clinical data received to date, this has not been 
identified as a safety concern for daprodustat. 
Exacerbation of rheumatoid arthritis 
In inflamed rheumatic joints, activation of HIF-related genes secondary to 
decreased oxygen and proinflammatory cytokines has been postulated to 
contribute to the neoangiogenesis, proliferation and infiltration of 
rheumatoid synovial fibroblasts [Westra, 2010; Muz, 2009]. 
No abnormalities were seen in non-clinical studies conducted to date. 
Following review of clinical data received to date, this has not been

Drug-drug interactions 
Daprodustat is a substrate of cytochrome P450 (CYP)2C8: 
Co-administration of daprodustat with a strong CYP2C8 inhibitor (i.e., 
gemfibrozil) increased the Cmax and AUC of daprodustat, 4- and 19-fold, 
respectively, while co-administration of a weak CYP2C8 inhibitor (i.e., 
trimethoprim) increased the Cmax and AUC of daprodustat by 1.3- and 
1.5-fold, respectively. Population PK analysis from completed Phase II 
studies suggests that co-administration of daprodustat with a moderate 
CYP2C8 inhibitor (i.e., clopidogrel) leads to a ~ 2-fold increase in AUC, 
with no clinically significant increase in the measured Hgb response. 
Although CYP2C8 induction studies were not performed, co-administration 
of daprodustat with an inducer of CYP2C8 (e.g. rifampin/rifampicin) may 
decrease the exposure of daprodustat. 
Even though co-administration of daprodustat with strong inhibitors and 
inducers of CYP2C8 is prohibited, inadvertent co-administration may 
occur. Due to the known time delay in enhancing erythropoiesis by 
daprodustat, co- administration with strong CYP2C8 inhibitors for up to 
14 days is not anticipated to lead to immediate marked increases in Hgb 
levels. Therefore, there is adequate time to change to alternate therapy 
that does not inhibit CYP2C8. 
Additionally, as the time for maximum induction of CYP2C8 occurs after

Potential Risk of Clinical Significance 
Summary of Data/Rationale for Risk 
Mitigation Strategy 
approximately 10 - 14 days of dosing with rifampin [Brodie, 2013; 
Ohnhaus, 1989], daprodustat systemic exposure will decrease over time 
which will result in a lag period before an effect on Hgb is recognized and 
is of clinical concern. 
Daprodustat is an inhibitor of CYP2C8:  
A clinical drug interaction study between 25 mg and 100 mg daprodustat 
with a CYP2C8 substrate (i.e., pioglitazone) showed that there is no PK 
interaction at these doses of daprodustat. 
Daprodustat is a substrate of breast cancer resistance protein (BCRP): 
Population PK analysis from Phase II studies suggested that while BCRP 
inhibitors were a covariate for daprodustat CL/F (8.6% lower clearance) the 
predicted change in exposure was not considered to be of clinical 
relevance. 
Daprodustat is an inhibitor of organic anion transporter polypeptide 
(OATP)1B1/1B3:  
A clinical drug interaction study between 25 mg and 100 mg daprodustat 
with an OATP1B1/1B3 substrate (i.e., rosuvastatin) showed that no PK 
interaction at this these doses of daprodustat.

Overall Benefit: Risk Conclusion 
Overall, the available data from non-clinical and clinical studies has not identified 
prohibitive risks associated with daprodustat at the exposures planned for this study.  
While there are a number of important potential risks identified for daprodustat, these 
can be addressed in clinical trials with proper subject selection, close safety 
monitoring, and specific risk characterization and mitigation.

STUDY DESIGN 
4.1. 
Overall Design 
This study consists of two parts; Part 1 is a single centre, single dose, open-label, 
randomised, 2-way crossover study in healthy Japanese male subjects. Part 2 is a

single centre, single dose in the fed and fasted state, open-label, randomised, 2-way 
crossover study in healthy Japanese male subjects.  
In both parts (Part 1 and Part 2), healthy subjects will have a screening visit within 30 
days prior to the first dose of study intervention, two intervention periods, and re-visit 
7 (±1) days after the second dose for follow-up. All subjects will be administered 
daprodustat as a single oral dose, with assessments conducted for up to 24 hours post-
dose. Subjects will be housed in the clinical research unit from Day -1 through Day 2 
of each period. At least 5-day wash-out period will occur between each intervention 
period. 
Subjects will participate in Parts 1 and 2, and receive the study intervention shown 
below;

Blood sampling for PK analysis will be performed prior to dosing and until 24 hours 
post-dose following each dose. The duration of each subject’s participation will be 
approximately 6 weeks from screening to the follow-up. 
Number of Participants 
Sufficient participants will be randomised such that approximately 52 and 12 (a total 
of 64 subjects) evaluable participants complete the study of Part 1 and Part 2, 
respectively. The definition of the study complete is described in the section 4.4. 
If participants prematurely discontinue the study, additional replacement participants 
may be recruited and assigned to the same treatment sequence at the discretion of the 
sponsor in consultation with the investigator. 
If PK parameters are not within the bioequivalence acceptance criterion because of an 
insufficient number of participants, one add-on participant study can be performed

using not less than half the number of participants with the same methodology as the 
initial study according to the Japanese BE guideline. 
4.2. 
Scientific Rationale for Study Design 
This is a 2-way crossover study design to compare the PK of daprodustat tablet (2 mg 
tablet vs. 4 mg tablet) and food effect on the PK of daprodustat following single oral 
doses in healthy Japanese male subjects. Part 1 is designed according to the Japanese 
BE guideline. To investigate the food effect in the closer clinical practice, a standard 
meal as recommended by the Japanese Society of Nephorology for chronic kidney 
disease [Jpn J Nephrol, 2014] will be used in Part 2. 
A previous single-dose study in healthy male Japanese subjects (PHI115385) using an 
earlier tablet formulation confirmed that the mean t1/2 of daprodustat from 10 
to100 mg was approximately 1.0 - 2.1 hours. Therefore, in this study, subjects will be 
hospitalised for 2 days in each period and undergo the examinations for safety 
assessments. The wash out between the 2 intervention periods is set to be ≥ 5 days, 
and the follow-up visit is set to be up to 7 (±1) days post the dose in Period 2. 
4.3. 
Justification for Dose 
A study is planned for the evaluation of the bioequivalence of daprodustat tablets 
(2 mg tablet vs. 4 mg tablet) (Part 1), because the dissolution tests of these tablets in 
water failed to demonstrate equivalence. To evaluate the bioequivalence of the 
daprodustat 2 mg and 4 mg tablet strengths, a single 4 mg dose has been selected for 
PK evaluation.  
To investigate the effect of food on the PK of daprodustat (Part 2), a single 4 mg dose 
which is the starting dose in Phase III studies in Japan has been selected. 
As of June 2017, more than 1700 patients and healthy subjects have received 
daprodustat. Overall, single oral doses of up to 500 mg (100 mg for Japanese) and 
repeated dose of up to 100 mg for 14 days administered to healthy subjects have been 
generally well tolerated.  
4.4. 
End of Study Definition 
A subject is considered to have completed the study if he has completed all phases of 
the study including the last scheduled procedure shown in the SoA. 
The end of the study is defined as the date of the last visit of the last subject in the 
study.

Study Intervention Compliance 
Subjects will receive study intervention directly from the investigator or designee, 
under medical supervision in the clinic. The date and time of each dose administered 
in the clinic will be recorded in the source documents. The dose of study intervention 
and study subject identification will be confirmed at the time of dosing by a member 
of the study site staff other than the person administering the study intervention. Study 
site personnel will examine each subject’s mouth to ensure that the study intervention 
was ingested. 
6.5. 
Concomitant Therapy 
Subjects must abstain from taking other prescription or non-prescription drugs 
(including vitamins and dietary or herbal supplements) within 14 days or 5 half-lives 
(whichever is longer) before the start of study intervention until completion of the 
follow-up visit, unless, in the opinion of the investigator and sponsor, the medication 
will not interfere with the study. 
6.6. 
Dose Modification 
This protocol allows no dose modification.

DISCONTINUATION OF STUDY INTERVENTION AND 
PARTICIPANT DISCONTINUATION/WITHDRAWAL 
7.1. 
Discontinuation of Study Intervention 
A subject may permanently discontinue study treatment at any time at his own request, 
or at the discretion of the investigator for safety or compliance reasons. A subject 
must permanently discontinue study intervention for the pre-specified reasons below. 
• 
Hgb value greater than the ULN. 
• 
Diagnosis of cancer (new or recurrent), with the exception of localized squamous 
cell or basal cell carcinoma of the skin. 
• 
Liver chemistry abnormalities exceeding the threshold criteria (Section 7.1.1). 
• 
QTc abnormalities exceeding the threshold criteria (Section 7.1.2). 
In all cases, the reason for study intervention discontinuation and the date of the last 
dose will be recorded in the subject’s case report form (CRF) and the subject will be 
withdrawn from the study as described in Section 7.2. 
7.1.1. 
Liver Chemistry Stopping Criteria 
Study intervention will be discontinued for a subject if liver chemistry stopping 
criteria are met:

Liver Safety Required Actions and Follow up Assessments Section can be found in 
Appendix 4. 
7.1.2. 
QTc Stopping Criteria 
The same QTc formula must be used for each individual subject to determine 
eligibility for and discontinuation from the study. This formula may not be changed or 
substituted once the subject has been enrolled. 
• 
For example, if a subject is eligible for the protocol based on QTcF, then 
QTcF must be used for discontinuation of this individual subject as well. 
• 
Once the QTc formula has been chosen for a subject’s eligibility, the same 
formula must continue to be used for that subject for all QTc data being 
collected for data analysis. Safety electrocardiograms (ECGs) and other non-
protocol specified ECGs are an exception.   
If the single QTc value meets either bulleted criterion, the additional double QTc 
values should be obtained over a brief (e.g. 5 - 10 minute) recording period. 
A subject that meets either bulleted criterion based on the average of triplicate ECG 
readings will be withdrawn from study intervention. 
• 
QTcF > 500 msec 
• 
Change from baseline:  QTc >60 msec 
See the SoA for data to be collected at the time of intervention discontinuation and 
follow-up and for any further evaluations that need to be completed. 
7.2. 
Participant Discontinuation/Withdrawal from the Study 
• 
A participant may withdraw from the study at any time at his own request, or 
may be withdrawn at any time at the discretion of the investigator for safety, 
behavioural, compliance or administrative reasons.  
• 
The participant will be permanently discontinued both from the study 
intervention and from the study at that time. 
• 
If the participant withdraws consent for disclosure of future information, the 
sponsor may retain and continue to use any data collected before such a 
withdrawal of consent. 
• 
If a participant withdraws from the study, he/she may request destruction of 
any samples taken and not tested, and the investigator must document this in 
the site study records. 
7.3. 
Lost to Follow Up 
A participant will be considered lost to follow-up if he repeatedly fails to return for 
scheduled visits and is unable to be contacted by the study site.  
The following actions must be taken if a participant fails to return to the clinic for a 
required study visit: 

2017N354137_00 
CONFIDENTIAL 
 
 
 
207727 
 
30 
 
• 
The site must attempt to contact the participant and reschedule the missed 
visit as soon as possible and counsel the participant on the importance of 
maintaining the assigned visit schedule and ascertain whether or not the 
participant wishes to and/or should continue in the study. 
• 
Before a participant is deemed lost to follow up, the investigator or designee 
must make every effort to regain contact with the participant (where possible, 
3 telephone calls and, if necessary, a certified letter to the participant’s last 
known mailing address or local equivalent methods). These contact attempts 
should be documented in the participant’s medical record. 
• 
Should the participant continue to be unreachable, he will be considered to 
have withdrawn from the study.  
 
8. 
STUDY ASSESSMENTS AND PROCEDURES 
• 
Study procedures and their timings are summarized in the SoA.  
• 
Protocol waivers or exemptions are not allowed.  
• 
Immediate safety concerns should be discussed with the sponsor 
immediately upon occurrence or awareness to determine if the subject should 
continue or discontinue study intervention. 
• 
Adherence to the study design requirements, including those specified in the 
SoA, is essential and required for study conduct. 
• 
All screening evaluations must be completed and reviewed to confirm that 
potential participants meet all eligibility criteria. The investigator will 
maintain a screening log to record details of all participants screened and to 
confirm eligibility or record reasons for screening failure, as applicable.  
• 
Procedures conducted as part of the participant’s routine clinical 
management (e.g. blood count) and obtained before signing of ICF may be 
utilized for screening or baseline purposes provided the procedure met the 
protocol-specified criteria and was performed within the time frame defined 
in the SoA. 
• 
The maximum amount of blood collected from each subject over the 
duration of the study, including any extra assessments that may be required, 
will not exceed 400 mL. 
• 
Repeat or unscheduled samples may be taken for safety reasons or for 
technical issues with the samples. 
8.1. 
Efficacy Assessments 
Efficacy assessments are not evaluated in this study. 
8.2. 
Safety Assessments 
Planned time points for all safety assessments are provided in the SoA.

8.2.1. 
Physical Examinations 
• 
A physical examination will include, at a minimum, assessments of the Skin, 
CV, Respiratory, GI and Neurological systems.  
• 
Height and weight will be measured and recorded at screening. 
• 
Investigators should pay special attention to clinical signs related to previous 
serious illnesses. 
8.2.2. 
Vital Signs 
• 
Axillary temperature, pulse, and blood pressure will be assessed. 
• 
Blood pressure and pulse measurements will be assessed with a completely 
automated device. Manual techniques will be used only if an automated 
device is not available. 
• 
Vital signs will be measured in a supine position after 5 minutes rest and will 
include temperature, systolic and diastolic blood pressure, and pulse. 
8.2.3. 
Electrocardiograms 
• 
Single 12-lead ECG will be obtained as outlined in the SoA using an ECG 
machine that automatically calculates the heart rate and measures PR, QRS, 
QT, and QTcF intervals. Refer to Section 7.1.2 for QTcF withdrawal criteria 
and additional QTcF readings that may be necessary. 
8.2.4. 
Clinical Safety Laboratory Assessments 
• 
Refer to Appendix 2 for the list of clinical laboratory tests to be performed 
and to the SoA for the timing and frequency.  
• 
The investigator must review the laboratory report, document this review, 
and record any clinically relevant changes occurring during the study in the 
adverse event (AE) section of the CRF. The laboratory reports must be filed 
with the source documents. Clinically significant abnormal laboratory 
findings are those which are not associated with the underlying disease, 
unless judged by the investigator to be more severe than expected for the 
subject's condition. 
• 
All laboratory tests with values considered clinically significantly abnormal 
during participation in the study should be repeated until the values return to 
normal or baseline or are no longer considered significantly abnormal by the 
investigator or medical monitor.  
• 
If such values do not return to normal/baseline within a period of time 
judged reasonable by the investigator, the aetiology should be identified and 
the sponsor notified. 
• 
All protocol-required laboratory assessments, as defined in Appendix 2 must 
be conducted in accordance with the laboratory manual and the SoA. 
8.3. 
Adverse Events and Serious Adverse Events 
The definitions of an AE or SAE can be found in Appendix 3. 

2017N354137_00 
CONFIDENTIAL 
 
 
 
207727 
 
32 
 
The investigator and any qualified designees are responsible for detecting, 
documenting, and reporting events that meet the definition of an AE or SAE and 
remain responsible for following up AEs that are serious, considered related to the 
study intervention or the study, or that caused the subject to discontinue the study 
intervention (see Section 7).  
8.3.1. 
Time Period and Frequency for Collecting AE and SAE 
Information 
• 
All SAEs will be collected from the start of intervention until the follow-up visit 
at the time points specified in the SoA. However, any SAEs assessed as related to 
study participation (e.g., study intervention, protocol-mandated procedures, or 
invasive tests) will be recorded from the time a subject consents to participate in 
the study. 
• 
All AEs will be collected from the start of intervention until the follow-up visit at 
the time points specified in the SoA. 
• 
Medical occurrences that begin before the start of study intervention but after 
obtaining informed consent will be recorded on the Medical History/Current 
Medical Conditions section of the CRF not the AE section. 
• 
All SAEs will be recorded and reported to the sponsor or designee immediately 
and under no circumstance should this exceed 24 hours, as indicated in Appendix 
3. The investigator will submit any updated SAE data to the sponsor within 
24 hours of it being available. 
• 
Investigators are not obligated to actively seek AEs or SAEs after the conclusion 
of study subjects. However, if the investigator learns of any SAE, including a 
death, at any time after a subject has been discharged from the study, and he 
considers the event to be reasonably related to the study intervention or study 
participation, the investigator must promptly notify the sponsor. 
8.3.2. 
Method of Detecting AEs and SAEs 
• 
The method of recording, evaluating, and assessing causality of AEs and SAEs 
and the procedures for completing and transmitting SAE reports are provided in 
Appendix 3. 
• 
Care will be taken not to introduce bias when detecting AE and/or SAE. Open-
ended and non-leading verbal questioning of the subject is the preferred method 
to inquire about AE occurrence. 
8.3.3. 
Follow-up of AEs and SAEs 
After the initial AE/SAE report, the investigator is required to proactively follow each 
subject at subsequent visits/contacts. All SAEs and non-serious AEs of special interest 
(as defined in Section 8.3.4) will be followed until the event is resolved, stabilized, 
otherwise explained, or the subject is lost to follow-up (as defined in Section 7.3). 
Further information on follow-up procedures is given in Appendix 3. 
8.3.4. 
Adverse Events of Special Interest (AESI) 
AESI have been identified based on non-clinical studies with daprodustat, clinical 
experience with recombinant human erythropoietins (rhEPOs), and current 

2017N354137_00 
CONFIDENTIAL 
 
 
 
207727 
 
33 
 
information regarding HIF-regulated pathways in mediating hypoxia-associated 
pathophysiology. The currently identified AESI for daprodustat are as follows: 
• Thrombosis and tissue ischemia secondary to excessive erythropoiesis 
• Death, MI, stroke, venous thromboembolism, thrombosis of vascular access 
• Cardiomyopathy 
• Pulmonary artery hypertension (PAH) 
• Increased cancer-related mortality and tumor progression and recurrence 
• Esophageal and gastric erosions 
• Proliferative retinopathy, macular edema, choroidal neovascularization 
• Exacerbation of rheumatoid arthritis 
8.3.5. 
Regulatory Reporting Requirements for SAEs 
• 
Prompt notification by the investigator to the sponsor of a SAE is essential 
so that legal obligations and ethical responsibilities towards the safety of 
subjects and the safety of a study intervention under clinical investigation are 
met.  
• 
The sponsor has a legal responsibility to notify both the local regulatory 
authority and other regulatory agencies about the safety of a study 
intervention under clinical investigation. The sponsor will comply with 
country-specific regulatory requirements relating to safety reporting to the 
regulatory authority, IRB, and investigators. 
• 
Investigator safety reports must be prepared for suspected unexpected 
serious adverse reactions (SUSAR) according to local regulatory 
requirements and sponsor policy and forwarded to investigators as necessary. 
• 
An investigator who receives an investigator safety report describing a SAE 
or other specific safety information (e.g. summary or listing of SAE) from 
the sponsor will review and then file it along with the IB and will notify the 
IRB, if appropriate according to local requirements. 
8.4. 
Treatment of Overdose 
For this study, any dose of daprodustat greater than 4 mg within a 24-hour time period 
will be considered an overdose. 
There is no specific antidote for overdose with daprodustat.  The expected 
manifestations of daprodustat overdose include signs and symptoms associated with 
an excessive and/or rapid increase in Hgb concentration. 
In the event of a suspected overdose, it is recommended that the appropriate 
supportive clinical care be instituted, as dictated by the subject’s clinical status. 
Additionally, subjects should be monitored closely for CV events, increased heart rate 
and haematologic abnormalities. 
In the event of an overdose, the investigator should: 
1. Contact the Medical Monitor immediately. 

2017N354137_00 
CONFIDENTIAL 
 
 
 
207727 
 
34 
 
2. Closely monitor the subject for AE/SAE and laboratory abnormalities until 
daprodustat can no longer be detected systemically (at least 14 days). 
3. Obtain a plasma sample for PK analysis within 14 days from the date of the last 
dose of study intervention if requested by the Medical Monitor (determined on a 
case-by-case basis). 
4. Document the quantity of the excess dose as well as the duration of the 
overdosing in the CRF. 
Decisions regarding dose interruptions or modifications will be made by the 
investigator in consultation with the Medical Monitor based on the clinical evaluation 
of the subject. 
8.5. 
Pharmacokinetics 
Blood samples of approximately 3 mL will be collected for measurement of plasma 
concentrations of daprodustat as specified in the SoA. Instructions for the collection 
and handling of biological samples will be provided by the sponsor. The actual date 
and time (24-hour clock time) of each sample will be recorded.

STATISTICAL CONSIDERATIONS 
The primary objective of Part 1 is to assess the bioequivalence of different 
daprodustat tablets strength (2 mg vs 4 mg) in healthy Japanese male subjects. 
The primary objective of Part 2 is to investigate food effect on PK of daprodustat in 
the fed state and fasted state in healthy Japanese male subjects. 
9.1. 
Statistical Hypotheses 
Part 1 
The bioequivalence between daprodustat 2 mg tablet and 4 mg tablet will be 
demonstrated using a framework of statistical hypothesis testing. The ratio of the 

2017N354137_00 
CONFIDENTIAL 
 
 
 
207727 
 
35 
 
geometric means (2mg/4mg) for AUC(0-t) and Cmax is the measure in the following 
statistical hypotheses: 
H0 (null hypothesis)  
: 2mg/4mg ≤ 0.80 or 2mg/4mg ≥ 1.25, 
H1 (alternative hypothesis) 
: 0.80 < 2mg/4mg < 1.25 
A judgment by 90% CI will be conducted in this study. The null hypothesis is rejected 
if the 90% confidence interval (CI) of 2mg/4mg falls within a range of 0.80 to 1.25, 
which results a conclusion of the bioequivalence. This is equivalent to carrying out 
two one-sided tests of hypothesis at the 5% level of significance.  
If the 90% CI of 2mg/4mg doesn’t fall within a range of 0.80 to 1.25 (i.e., null 
hypothesis is not rejected), the bioequivalence is established if the point estimate 
(2mg/4mg) falls within a range of 0.90 to 1.11. 
Part 2 
No formal statistical hypotheses will be tested. 
9.2. 
Sample Size Determination 
Part 1 
Refer to regulatory definition of bioequivalence criteria; 90% CI of the ratio for 
AUC(0-t) and Cmax between tablet strengths (2 mg x 2 vs. 4 mg x 1) should lie in the 
range of 0.80-1.25. Assuming the true ratio is 1.0 and the coefficient of variation 
within subject (%CVw) is 35%, in a 2-way crossover design 52 subjects in total (i.e. 
26 subjects for each group) will be randomised to achieve at least 90% power for 
meeting the bioequivalence criteria.  
The %CVw has been assumed conservatively from Japanese data in the previous 
Japanese study (PHI115385, Part 1) based on a power model using all dose groups. 
The power model used to estimate %CVw is as below. 
loge(PK parameter) =  + Si + β*log(Dj) + εij 
where  is the intercept, β is the slope, Si is the random effect for subject i, Dj is the 
dose, εij is the random error. The %CVw estimates based on the random error are 
24.3% and 26.8% for AUC(0-inf) and Cmax, respectively. For a little more 
conservative looking at higher variation in lower strength doses, an estimate 
of %CVw has been set to be 35% for sample size considerations.  
Part 2 
The number of subjects is determined based on the feasibility rather than statistical 
considerations. A total of 12 subjects (i.e. 6 subjects for each group) will be 
randomised in a 2-way crossover design. Assuming a %CVw of 35% for AUC(0-t) 
and Cmax as described, it is estimated that the lower and upper bounds of the 90% CI 
for the ratio of AUC(0-t) and Cmax in the fed and fasted state will be within +/- 30%. 
If the estimated ratio is 1.0, its 90% CI would be approximately (0.78, 1.29).

Enrolled 
All subjects who signed the ICF 
Safety 
This population will be defined for each Part. 
• All randomised subjects who received at least one dose of 
study intervention. 
PK 
This population will be defined for each Part. 
• All subjects in the Safety population who had at least 1 non-
missing PK assessment (Non-quantifiable [NQ] values will be 
considered as non-missing values). 
 
9.4. 
Statistical Analyses 
9.4.1. 
Pharmacokinetic Analyses 
All PK analyses will be performed on the PK Population for each Part.  
For each tablet strength (Part 1) and the fed and fasted state (Part 2), the plasma 
concentrations of daprodustat will be summarized by nominal time and individual 

2017N354137_00 
CONFIDENTIAL 
 
 
 
207727 
 
37 
 
plasma concentration-time profiles and median/mean profiles will be plotted. Each of 
the figures will contain one plot on the untransformed scale (i.e. a linear plot) and one 
plot on the log transformed scale (i.e. a log-linear plot). 
For both Part 1 and Part 2, from the plasma concentration-time data, the following PK 
parameters will be determined by non-compartmental methods with Phoenix 
WinNonlin (version 6.3 or higher), as data permit: AUC(0-t), AUC(0-inf), Cmax, 
Tmax, t1/2, %AUCex, CL/F, Vz/F, kel, MRT, and correlation coefficient between 
time and log concentration of daprodustat for the points used in estimation of kel. The 
bioequivalence between the tablets will be confirmed with comparisons of the values 
of the logarithmic parameters [AUC(0-t) and Cmax]. 
Calculations will be based on the actual sampling times recorded during the study. PK 
data, except for the correlation coefficient between time and log concentration for the 
points used in estimation of kel, will be presented in graphical and/or tabular form and 
will be summarized descriptively, using summary statistics (n, arithmetic mean with 
associated 95% CI, standard deviation (SD), minimum, median, and maximum). 
Except for Tmax, geometric mean with associated 95% CI, SD on loge scale and 
coefficient of variation between subjects (%CVb) will also be provided. Listings will 
be generated for each derived plasma PK parameters. 
The following statistical analysis methods will be used to assess the bioequivalence in 
Part 1 and the food effect in Part 2: 
Part 1 
Statistical Analysis Methods 
The exposure (Cmax and AUC(0-t)) of daprodustat will be assessed by using a mixed 
effect model as described below: 
loge (PK parameter) = 0 +i + j + k + l + εijkl 
where 0 is the intercept, i is the random subject effect for ith subject, j is the tablet 
strength effect (j = 2 mg or 4 mg), k is the period effect (k = period 1 or period 2), l is 
the group effect (l= group A or group B), and εijkl is the random error. The Kenward-
Roger degree of freedom approach will be used.  
Point estimates (loge) for the model-based means of PK parameters on loge scale will be 
provided for each tablet strength and a point estimate of the mean difference between 
tablet strengths (loge2mg - loge4mg) will be constructed along with the associated 90% 
CIs using the residual variances. The point estimates, the point estimate of the mean 
difference, and the associated 90% CIs on loge scale will be exponentially back-
transformed to obtain the model-based geometric means (), and the ratio for AUC(0-t) 
and Cmax (2mg/4mg) and the associated 90% CIs, respectively.  
The bioequivalence will be evaluated using the following criteria of Japan BE guideline. 
Evaluate using criterion 1 first, if criteria are not met, criterion 2 is used. 
• 
Criterion 1 
The 90% CIs of the ratios of the geometric means for AUC(0-t) and Cmax 
(2mg/4mg ) are within the range of 0.80 - 1.25.

• 
Criterion 2 
The ratio of the geometric means for AUC(0-t) and Cmax (2mg/4mg) is within the 
range of 0.90 - 1.11. 
 
Part 2 
Statistical Analysis Methods 
To estimate the food effect on PK parameters (Cmax and AUC(0-t)) of daprodustat, the 
PK parameters will be analysed using a mixed effect model as described as below: 
loge (PK parameter) = 0 +i + j + k + l + εijkl 
where 0 is the intercept, i is the random subject effect for ith subject, j is the food effect 
(j = fed or fasted), k is the period effect (k = period 1 or period 2), l is the group effect 
(l= group C or group D), and εijkl is the random error. The Kenward-Roger degree of 
freedom approach will be used. 
Point estimates (loge) for the model-based means of PK parameters on loge scale will be 
provided for the fed and fasted state and a point estimate of the mean difference between 
fed and fasted state (logefed - logefasted) will be constructed along with the associated 
90% CIs using the residual variances. The point estimates, the point estimate of the mean 
difference, and the associated 90% CIs on loge scale will be exponentially back-
transformed to obtain the model-based geometric means (), the ratio for AUC(0-t) and 
Cmax (fed/fasted) and the associated 90% CIs, respectively. 
 
9.4.2. 
Safety Analyses 
All safety analyses will be performed on the Safety Population for each Part.  
Safety data will be presented in tabular and/or graphical format and summarized 
descriptively according to GSK’s Integrated Data Standards Library (IDSL) standards. 
AEs, changes from baseline in clinical laboratory tests, vital signs (blood pressure, 
pulse and body temperature), and 12-lead ECG parameters will be summarized for 
each tablet strength (Part 1) and the fed or fasted state (Part 2). No statistical 
comparison will be made for the safety summaries. 
9.5. 
Interim Analyses 
No interim analysis is planned in this study.

A manuscript will be progressed for publication in the scientific literature if 
the results provide important scientific or medical knowledge. 
10.1.6. 
Data Quality Assurance 
• 
All subject data relating to the study will be recorded on printed or electronic 
CRF unless transmitted to the sponsor or designee electronically (e.g. 
laboratory data). The investigator is responsible for verifying that data 
entries are accurate and correct by physically or electronically signing the 
CRF.  
• 
The investigator must maintain accurate documentation (source data) that 
supports the information entered in the CRF.  
• 
The investigator must permit study-related monitoring, audits, IRB review, 
and regulatory agency inspections and provide direct access to source data 
documents.  
• 
Monitoring details describing strategy (e.g. risk-based initiatives in 
operations and quality such as Risk Management and Mitigation Strategies 
and Analytical Risk-Based Monitoring), methods, responsibilities and 
requirements, including handling of noncompliance issues and monitoring 
techniques (central, remote, or on-site monitoring) are provided in the 
Monitoring Plan. 
• 
The sponsor or designee is responsible for the data management of this study 
including quality checking of the data.  
• 
The sponsor assumes accountability for actions delegated to other 
individuals (e.g. Contract Research Organizations). 
• 
Study monitors will perform ongoing source data verification to confirm that 
data entered into the CRF by authorized 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 ICF, pertaining to the conduct of 
this study must be retained by the investigator for 25 years from the issue of 
the final CSR/ equivalent summary 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.  
10.1.7. 
Source Documents 
• 
Source documents provide evidence for the existence of the subject and 
substantiate the integrity of the data collected. Source documents are filed at 
the investigator’s site.

source documents. 
10.1.8. 
Study and Site Closure 
GSK or its designee reserves the right to close the study site or terminate the study at 
any time for any reason at the sole discretion of GSK. Study sites will be closed upon 
study completion. A study site is considered closed when all required documents and 
study supplies have been collected and a study-site closure visit has been performed. 
The investigator may initiate study-site closure at any time, provided there is 
reasonable cause and sufficient notice is given in advance of the intended termination. 
Reasons for the early closure of a study site by the sponsor or investigator may 
include but are not limited to: 
• 
Failure of the investigator to comply with the protocol, the requirements of 
the IRB or local health authorities, the sponsor's procedures, or GCP 
guidelines 
• 
Inadequate recruitment of subjects by the investigator 
• 
Discontinuation of further study intervention development 
10.1.9. 
Publication Policy 
• 
The results of this study may be published or presented at scientific meetings. 
If this is foreseen, the investigator agrees to submit all manuscripts or 
abstracts to the sponsor before submission. This allows the sponsor to protect 
proprietary information and to provide comments.  
• 
The sponsor will comply with the requirements for publication of study 
results. In accordance with standard editorial and ethical practice, the 
sponsor will generally support publication of multicentre studies only in their 
entirety and not as individual site data. In this case, a coordinating 
investigator will be designated by mutual agreement. 
• 
Authorship will be determined by mutual agreement and in line with 
International Committee of Medical Journal Editors authorship requirements.

10.3. 
Appendix 3: Adverse Events: Definitions and Procedures 
for Recording, Evaluating, Follow-up, and Reporting 
10.3.1. 
Definition of AE 
AE Definition 
• 
An AE is any untoward medical occurrence in a clinical study subject, temporally 
associated with the use of a study intervention, whether or not considered related 
to the study intervention. 
• 
NOTE: An AE can therefore be any unfavourable and unintended sign (including 
an abnormal laboratory finding), symptom, or disease (new or exacerbated) 
temporally associated with the use of a study intervention. 
 
Events Meeting the AE Definition 
• 
Any abnormal laboratory test results (haematology, clinical chemistry, or 
urinalysis) or other safety assessments (e.g. ECG, radiological scans, vital signs 
measurements), including those that worsen from baseline, considered clinically 
significant in the medical and scientific judgment of the investigator (i.e., not 
related to progression of underlying disease). 
• 
Exacerbation of a chronic or intermittent pre-existing condition including either 
an increase in frequency and/or intensity of the condition. 
• 
New conditions detected or diagnosed after study intervention administration 
even though it may have been present before the start of the study. 
• 
Signs, symptoms, or the clinical sequelae of a suspected drug-drug interaction. 
• 
Signs, symptoms, or the clinical sequelae of a suspected overdose of either study 
intervention or a concomitant medication. Overdose per se will not be reported as 
an AE/SAE unless it is an intentional overdose taken with possible suicidal/self-
harming intent. Such overdoses should be reported regardless of sequelae. 
 
Events NOT Meeting the AE Definition  
• 
Any clinically significant abnormal laboratory findings or other abnormal safety 
assessments which are associated with the underlying disease, unless judged by 
the investigator to be more severe than expected for the subject’s condition. 
• 
The disease/disorder being studied or expected progression, signs, or symptoms 
of the disease/disorder being studied, unless more severe than expected for the 
subject’s condition. 
• 
Medical or surgical procedure (e.g. endoscopy, appendectomy): the condition that 
leads to the procedure is the AE. 
• 
Situations in which an untoward medical occurrence did not occur (social and/or 
convenience admission to a hospital). 
• 
Anticipated day-to-day fluctuations of pre-existing disease(s) or condition(s) 

2017N354137_00 
CONFIDENTIAL 
 
 
 
207727 
 
46 
 
present or detected at the start of the study that do not worsen. 
 
10.3.2. 
Definition of SAE 
If an event is not an AE per definition above, then it cannot be an SAE even if serious 
conditions are met (e.g. hospitalization for signs/symptoms of the disease under study, 
death due to progression of disease). 
A SAE is defined as any untoward medical occurrence that, at any dose: 
a. Results in death 
b. Is life-threatening 
The term '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. 
c. Requires inpatient hospitalization or prolongation of existing hospitalization 
In general, hospitalization signifies that the subject has been detained (usually 
involving at least an overnight stay) at the hospital or emergency ward for observation 
and/or treatment that would not have been appropriate in the physician’s office or 
outpatient setting. Complications that occur during hospitalization are AE. If a 
complication prolongs hospitalization or fulfils any other serious criteria, the event is 
serious. When in doubt as to whether “hospitalization” occurred or was necessary, the 
AE should be considered serious. 
Hospitalization for elective treatment of a pre-existing condition that did not worsen 
from baseline is not considered an AE. 
d. Results in persistent disability/incapacity 
• 
The term disability means a substantial disruption of a person’s ability to conduct 
normal life functions. 
• 
This definition is not intended to include experiences of relatively minor medical 
significance such as uncomplicated headache, nausea, vomiting, diarrhoea, 
influenza, and accidental trauma (e.g. sprained ankle) which may interfere with 
or prevent everyday life functions but do not constitute a substantial disruption. 
e. Is a congenital anomaly/birth defect 
f. Other situations: 
• 
Medical or scientific judgment should be exercised in deciding whether SAE 
reporting is appropriate in other situations such as important medical events that 
may not be immediately life-threatening or result in death or hospitalization but 
may jeopardize the subject or may require medical or surgical intervention to 
prevent one of the other outcomes listed in the above definition. These events 
should usually be considered serious. 
Examples of such events include invasive or malignant cancers, intensive 

2017N354137_00 
CONFIDENTIAL 
 
 
 
207727 
 
47 
 
treatment in an emergency room or at home for allergic bronchospasm, blood 
dyscrasias or convulsions that do not result in hospitalization, or development of 
drug dependency or drug abuse. 
 
10.3.3. 
Recording and Follow-Up of AE and SAE 
AE and SAE Recording 
• 
When an AE/SAE occurs, it is the responsibility of the investigator to review all 
documentation (e.g. hospital progress notes, laboratory, and diagnostics reports) 
related to the event. 
• 
The investigator will then record all relevant AE/SAE information in the CRF. 
• 
It is not acceptable for the investigator to send photocopies of the subject’s 
medical records to GSK in lieu of completion of the GSK/AE/SAE CRF page. 
• 
There may be instances when copies of medical records for certain cases are 
requested by GSK. In this case, all subject identifiers, with the exception of the 
subject number, will be redacted on the copies of the medical records before 
submission to GSK. 
• 
The investigator will attempt to establish a diagnosis of the event based on signs, 
symptoms, and/or other clinical information. Whenever possible, the diagnosis 
(not the individual signs/symptoms) will be documented as the AE/SAE. 
Assessment of Intensity 
The investigator will make an assessment of intensity for each AE and SAE reported 
during the study and assign it to 1 of the following categories:  
• 
Mild: An event that is easily tolerated by the subject, causing minimal discomfort 
and not interfering with everyday activities. 
• 
Moderate: An event that causes sufficient discomfort and interferes with normal 
everyday activities. 
• 
Severe: An event that prevents normal everyday activities. An AE that is assessed 
as severe should not be confused with an SAE. Severe is a category utilized for 
rating the intensity of an event; and both AE and SAE can be assessed as severe. 
An event is defined as ‘serious’ when it meets at least 1 of the predefined 
outcomes as described in the definition of an SAE, NOT when it is rated as 
severe.  
 
Assessment of Causality 
• 
The investigator is obligated to assess the relationship between study intervention 
and each occurrence of each AE/SAE. 
• 
A "reasonable possibility" of a relationship conveys that there are facts, evidence, 
and/or arguments to suggest a causal relationship, rather than a relationship 
cannot be ruled out. 
• 
The investigator will use clinical judgment to determine the relationship. 

2017N354137_00 
CONFIDENTIAL 
 
 
 
207727 
 
48 
 
• 
Alternative causes, such as underlying disease(s), concomitant therapy, and other 
risk factors, as well as the temporal relationship of the event to study intervention 
administration will be considered and investigated. 
• 
The investigator will also consult the IB and/or Product Information, for 
marketed products, in his/her assessment. 
• 
For each AE/SAE, the investigator must document in the medical notes that 
he/she has reviewed the AE/SAE and has provided an assessment of causality. 
• 
There may be situations in which an SAE has occurred and the investigator has 
minimal information to include in the initial report to GSK. However, it is very 
important that the investigator always make an assessment of causality for 
every event before the initial transmission of the SAE data to GSK. 
• 
The investigator may change his/her opinion of causality in light of follow-up 
information and send an SAE follow-up report with the updated causality 
assessment. 
• 
The causality assessment is one of the criteria used when determining regulatory 
reporting requirements. 
 
Follow-up of AE and SAE 
• 
The investigator is obligated to perform or arrange for the conduct of 
supplemental measurements and/or evaluations as medically indicated or as 
requested by GSK to elucidate the nature and/or causality of the AE or SAE as 
fully as possible. This may include additional laboratory tests or investigations, 
histopathological examinations, or consultation with other health care 
professionals. 
• 
If a subject dies during participation in the study or during a recognized follow-
up period, the investigator will provide GSK with a copy of any post-mortem 
findings including histopathology. 
• 
New or updated information will be recorded in the originally completed CRF. 
• 
The investigator will submit any updated SAE data to GSK within 24 hours of 
receipt of the information. 
 
10.3.4. 
Reporting of SAE to GSK 
SAE Reporting to GSK via Electronic Data Collection Tool 
• 
The primary mechanism for reporting SAE to GSK will be the electronic data 
collection tool. 
• 
If the electronic system is unavailable, then the site will use the paper SAE data 
collection tool in order to report the event within 24 hours. 
• 
The site will enter the SAE data into the electronic system as soon as it becomes 
available. 
• 
The investigator or medically-qualified sub-investigator must show evidence 
within the eCRF (e.g. check review box, signature, etc.) of review and 
verification of the relationship of each SAE to IP/study participation (causality) 

2017N354137_00 
CONFIDENTIAL 
 
 
 
207727 
 
49 
 
within 72 hours of SAE entry into the eCRF. 
• 
After the study is completed at a given site, the electronic data collection tool will 
be taken off-line to prevent the entry of new data or changes to existing data. 
• 
If a site receives a report of a new SAE from a study subject or receives updated 
data on a previously reported SAE after the electronic data collection tool has 
been taken off-line, then the site can report this information on a paper SAE form 
or to the medical monitor by telephone. 
• 
Contacts for SAE reporting can be found in Appendix 5.
