Brief summary:
This study is the first administration of GSK2983559, a selective receptor interacting protein 2 (RIP2) kinase inhibitor, to humans. This will be randomized, double-blinded (sponsor open) and two part study (A and B). Part A of the study is single ascending dose crossover design with two separate cohorts (1 and 2). In Part A, 9 single dose levels will be explored. In Cohort 1, 10 healthy subjects will randomized to receive single oral doses of either GSK2983559 or placebo in a ratio of 4:1 in 5 way cross-over design with 5 treatment periods. In Cohort 2, 8 healthy subjects will be randomized to receive single oral doses of either GSK2983559 or placebo in a ratio of 3:1 in 4 way cross-overs design with 4 treatment periods. In Cohort 2 there will be an additional period (period 5-open label) for assessing GSK2983559 under fed conditions. There will be 48 hours wash-out period between each dose escalation period. Part B is repeat ascending dose sequential group design. It will contain 4 Cohorts of and dosing will be done sequential dosing. Subjects in Part B will receive once daily (QD) dose or twice daily dose (will be decided based upon the pharmacokinetic, safety and tolerability observed in Part A). There will 58 subjects involved in this study. Total duration of Part A will be approximately for 11 Weeks and Part B will be approximately for 15 Weeks.

Detailed description:

Original Protocol
06-OCT-2017
Amendment 01 24-JUL-2018
Overall Rationale for the Amendment:
As described in Section 5.5.5 and Section 8.2 of this protocol,  plasma concentrations of 
the mutagenic substance 5-ABT and its metabolite NAc-5-ABT are being monitored 
throughout the study to ensure that participants remain below the threshold of 
toxicological concern (TTC) of  <120 µg/day (for up to one month of dosing) as defined 
by the ICH M7 guidance.  Following administration of  a single dose of 100 mg 
GSK2983559 in Cohort 1 of Part A, quantifiable concentrations of 5-ABT were observed 
in 4 of the 8 subjects dosed with GSK2983559.  The maximum observed 5-ABT 
concentration of 1.25 ng/mL was below the stopping criteria of 3 ng/mL.  The presence 
of quantifiable concentrations of 5-ABT in plasma is believed to be due to hydrolysis of 
the drug substance to form 5-ABT in the acidic conditions of the stomach.  It is also 
known that the drug product contains 5-ABT; however, this is being controlled to < 10 
ppm in the current synthetic route and extraction procedure. 
This amendment will change the formulation from a standard capsule (HPMC) to an 
enteric capsule (HPMCAS) to determine if an enteric formulation minimises the gastric 
conversion of drug substance to  5-ABT.  The disintergration of an enteric capsule is pH 
dependent and is expected to avoid hydrolysis in the stomach and release active 
pharmaceutical ingredient (API) in the higher pH environment in the proximal small 
intestine. The 5-ABT stopping criteria are unchanged and continue with progression in to 
Cohort 2 and if controlled will carry through Cohort 6.
PK parameters AUC and Cmax for GSK2983559 and GSK2668176 increase 
approximately linearly with increasing doses.  Draft preliminary review of blinded safety 
data indicate that there are no clinical significant safety concerns.  No SAEs or deaths 
have been reported. Cohort 2 is planned to start with a 200 mg dose and escalate to the 
top predicted dose which values will not exceed the mean GSK2668176 AUC(0-24) and 
Cmax values observed at one third of the No Observable Effect Limit (NOAEL) in 
minipig. The sample size for Cohort 2 will be increased from 8 to 12 subjects to monitor 
for 5-ABT concentrations in more subjects and to ensure at least 8 active subjects 
progress to the food effect dosing in this cohort.

Overall Design:
This study will be a randomised, double-blind (sponsor open), placebo-controlled, two-
part study of oral administration of GSK2983559 in healthy participants. Part A will be a 
single ascending dose crossover design in two separate cohorts of participants (Cohorts 1 
and 2). In addition to the crossover treatment periods, subjects in Cohort 2 will participate 
in an additional treatment period and receive open-label GSK2983559 under fed 
conditions. Part B will be a repeat dose design in up to 4 cohorts of participants (Cohorts 
3-6). This study is planned to include approximately 62 participants.
Parts A and B of this study will be double-blind with respect to participants, investigator 
and site staff (except for the site pharmacist). Sponsor open refers only to members of the 
Dose Escalation Committee (DEC) at defined meetings. Members and requirements are 
provided in a Dose Escalation Charter. 

Part A – single ascending doses, randomized, placebo controlled, crossover.
Part A plans to explore up to 9 single ascending dose levels. This will be 2 cohorts, 
Cohort 1 (standard capsule) and Cohort 2 (enteric capsule), of 10 and 12 healthy 
participants, respectively. The total duration of Part A of the study for each participant, 
including screening and follow-up, is approximately 11 weeks.

Part B – repeat ascending dose, randomized, placebo controlled, sequential-group.
Part B will consist of up to four cohorts of 10 healthy participants. The total duration of 
Part B of the study for each participant, including screening and follow-up, is 
approximately 15 weeks. The treatment period will be 14 days.
In all cases the decision to proceed to the next dose level will be made at a DEC meeting 
(see Study Governance Considerations).

SCHEDULE OF ACTIVITIES (SOA)
The schedules of activities (SOA) for Part A and Part B are presented in Table 2 and 
Table 3, respectively.  The time points for the PK blood sample collection in Part A and 
Part B are presented in Table 2 and Table 4, respectively.
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 a result of emerging pharmacokinetic data must be documented and approved by the 
relevant study team members and then archived in the sponsor and site study files. The 
competent authority (CA) and ethics committee (EC) 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 CA and the EC before implementation.
There are times where the protocol requires more than one procedure to be completed at 
the same time point. In these instances the following will apply to post dose time points:
PK samples should take priority over other procedures scheduled at the same time point. 
As guidance, the preferred order of assessments is:

Electrocardiograms (ECGs)

Vital Signs

PK blood sampling (nominal time)

Other assessments e.g., physical exams, 
Electrocardiograms (ECGs) should be taken prior to vital signs when both measurements 
are scheduled at the same time point.  Other assessments, e.g., physical examinations etc, 
will be performed within the required time windows.  All safety assessments will be 
timed and performed relative to the start of dosing.

INTRODUCTION
3.1.
Study Rationale
This study is the first administration of GSK2983559, a selective RIP2 kinase inhibitor, 
to humans.  The purpose of this study is to evaluate the safety, tolerability, 
pharmacokinetics (PK), and exploratory pharmacodynamics (PD) of single (fed and 
fasted) and repeat oral doses of up to 14 days with GSK2983559 in healthy participants.  
The intention of this study is to provide sufficient confidence in the safety of the 
molecule to inform progression to further repeat dose proof of concept studies.
3.2.
Background
GSK2983559 is a novel oral first-in-class inhibitor of Receptor Interacting Protein 
Kinase-2 (RIPK2). GSK2983559 is a phosphate ester pro-drug, which breaks down 
rapidly into GSK2668176 providing an increase in solubility and exposure. GSK2668176 
is a potent, reversible, and highly-selective inhibitor of RIP2 kinase (RIPK2).
RIPK2 is a serine/threonine kinase, comprised of an N-terminal kinase domain, an 
intermediate domain, and C-terminal caspase-activation-and-recruitment (CARD) 
domain. The nucleotide-binding oligomerization domain 1 (NOD1)/RIP2 and 
NOD2/RIP2 pathways are widely expressed in both immune and non-immune cells. 
Upon activation RIP2 undergoes post-translational modifications (ubiquitination and 
autophosphorylation), which facilitate NF-κB and mitogen-activated protein kinase 
(MAPK) activation, and lead to release of multiple proinflammatory cytokines (e.g., 
tumour necrosis factor [TNF], interleukin [IL]-1, -6, -8, etc.). Properly regulated, these 
pathways play an important role in maintaining innate immune homeostasis and host 
defense. 
Dysregulation of these pathways has been linked to multiple inflammatory diseases.  
Mutations in the Leucine-rich repeat (LRR) domain of NOD2 have been linked to 
increased susceptibility to Crohn’s disease (CD). In both CD and ulcerative colitis (UC) a 
breakdown in intestinal immune homeostasis is associated with disruption of epithelial 
barrier integrity, leading to inappropriate interaction between commensal bacteria and 
mucosal immune cells, aberrant activation of pattern recognition receptors (PRRs), and 
RIPK2-dependent inflammation. Activating mutations in the nucleotide binding domain 
of NOD2 have been linked to Blau Syndrome, a rare, monogenic, autoinflammatory 
disease characterized by granulomatous inflammation affecting multiple organs, often 
presenting with the clinical trial of arthritis, uveitis, and dermatitis. RIP2-dependent 
signaling has also been implicated in additional inflammatory diseases, including 
rheumatoid arthritis, psoriasis, vasculitis, type 2 diabetes, and multiple sclerosis.
3.3.
Benefit/Risk Assessment
To date, GSK2983559 has not been administered to human participants; therefore, no 
clinical data are available.  This is the first single and repeat dose study proposed in 
human participants with GSK2983559.  GlaxoSmithKline is not aware of any compound 
targeting this pathway having previously been administered in humans.

The risk assessment of GSK2983559 is based on the pre-clinical studies conducted to 
date.  More detailed information about the known and expected benefits and risks and 
reasonably expected adverse events of GSK2983559 can be found in the GSK2983559 
Investigator’s Brochure [GlaxoSmithKline Document Number 2016N308990_00].  
Details of these risks and the proposed strategy to mitigate/monitor these risks are 
detailed in Section 3.1 below.  The proposed risk assessment and management plan for 
the study has been developed in accordance with the tenets of European Medicines 
Agency (EMA) guideline on strategies to identify and mitigate risks for first time in 
human (FTiH) clinical trials with investigational medicinal products [European 
Medicines Evaluation Agency (EMEA)/ Committee for Medicinal Products for Human 
Use (CHMP)/SWP/28367/07].  GlaxoSmithKline (GSK) has assessed this study for any 
risks that may be posed to participants taking part.  Only healthy male and female 
participants of non-child bearing potential (NCBP) will participate in this study.

Neurobehavioral effects
Non-clinical data:
Non-reproducible neurobehavioural observations in an 
acute study in rats at doses ≥15mg/kg/day (vocalisation, 
increased touch response, grip strength and body tone).
No central nervous system (CNS)-related clinical signs 
were seen in any other acute or repeat dose study in rats, 
dogs or minipigs.
Participant Selection:

Participants with known history of significant 
neurological or psychiatric disorders or suicidal 
ideation behaviour will be excluded from 
GSK2983559 clinical studies.  

Participants with potentially increased 
susceptibility for neurologic or psychiatric effects 
will be excluded based on medical history at 
screening.
Participant Monitoring:

Targeted physical examinations with 
comprehensive neurological assessments will be 
conducted at appropriate intervals throughout 
the study.

Participants will be monitored for standard CNS-
related adverse events (AEs). Common 
terminology criteria for adverse events (CTCAE)
Nervous System Stopping Criteria are included 
in the protocol.

Potential Risk of Clinical Significance
Summary of Data/Rationale for Risk
Mitigation Strategy
Immunosuppression
There is a theoretical risk of immunosuppression, including 
an increase in the frequency and/or severity of infection, 
resulting from the intended pharmacologic effect of 
GSK2983559.
Participant Selection:

Participants with recurrent, chronic or active 
infections will be excluded from GSK2983559
clinical studies.

Participants will be screened for tuberculosis 
(TB), human immunodeficiency virus (HIV), and 
Hepatitis B and C, and excluded from this study.
Participant Monitoring:

Participants will be monitored for signs of 
infection.
Vaccinations
There is a theoretical risk that GSK2983559 could 
decrease a participant’s immune response to vaccines or 
allow symptoms to develop following vaccination with a live 
vaccine when administered on therapy.  Currently, there
are no preclinical or clinical data with respect to this 
potential risk.
Participant Selection:

Routine or planned attenuated or live vaccines 
should not be administered to participants for 
30 days prior to the first dose of GSK2983559, 
during study participation, and for 5 half-lives 
plus 30 days after receiving GSK2983559.

Non-live vaccines (e.g., inactivated influenza 
vaccines) may be administered while receiving 
GSK2983559.

Potential Risk of Clinical Significance
Summary of Data/Rationale for Risk
Mitigation Strategy
Hepatotoxicity
Non-clinical data:
Increased mean serum glutamate dehydrogenase (GLDH) 
and alanine aminotransferase (ALT) concentrations 
correlated with mixed inflammatory cell infiltrates present 
around the bile duct regions in the liver in female rats given 
240 mg/kg/day (6-week study). These changes were not 
observed in male rats at any dose. Additional liver findings, 
including hepatocellular necrosis, have been observed in 
rats and minipigs at non-tolerated doses.
Participant Monitoring:

Clinical hematologic and chemistry laboratory 
tests are readily measurable in the clinic and will 
be monitored periodically throughout the study 
(see SoA in Section 2). 

Liver Chemistry Stopping Criteria are included in 
the clinical protocol.
Phototoxicity
Non-clinical data:
There is a potential risk that GSK2983559 can lead to 
photosensitivity responses in some people.  
In a ultraviolet/visible light (UV/VIS) spectrum for 
GSK2983559 (max abs [absorbance] 340 nm) and 
GSK2668176 (max abs 339 nm) in acetonitrile 
(ACN)/water showed an absorbance between 290-700 nm 
demonstrated a risk for potential phototoxicity effects.
Participant Selection:

Participants must agree to avoid prolonged UV 
exposure to natural sunlight or tanning beds for 
the duration of the study.

Participants should be advised to wear protective 
clothing (e.g., sun hat, long sleeves) covering 
exposed areas and use a broad spectrum 
ultraviolet A/ultraviolet B (UVA/UVB) sunscreen 
and lip balm (SPF ≥30) on exposed areas when 
outdoors for a minimum of 5 half-lives after 
receiving GSK2983559.  Participants should also 
wear sunglasses which filter UVA and UVB rays 
for a minimum of 5 half-lives after receiving 
GSK2983559.  
Participant Monitoring:

Participants should be monitored for adverse 
effects potentially related to phototoxicity.

Potential Risk of Clinical Significance
Summary of Data/Rationale for Risk
Mitigation Strategy
Mutagenicity/
Genotoxicity
Non-clinical data:
5-amino-benzothiazole (5-ABT), an impurity and acid 
degradant, is mutagenic in an in vitro Ames assay.  It is 
unknown if GSK2983559 itself presents a genotoxic 
hazard to humans.
Participant Monitoring:

Plasma samples from FTIH will be analysed for 
5ABT and N-acetyl 5ABT at each dose level. 
Dose escalation will be halted if in any individual 
the Cmax of combined concentration of 5-ABT 
and n-acetyl-5-amino benzothiazole (NAc-5-
ABT) (in ng/mL equivalents 5-ABT) is > 3 ng/mL
in either the standard or enteric capsule.
Reproductive toxicity
Non-clinical data:
Animal reproductive studies have not been conducted with 
GSK2983559.  Therefore, the compound must not be 
administered to pregnant women, nursing mothers or 
women of childbearing potential.
Subject Selection:

Male and female participants of non-childbearing 
potential (WONCBP) may be included in this 
study.

Male participants must agree to use highly 
effective methods of contraception during the 
treatment period and for at least 5 half-lives plus 
an additional 90 days after the last dose of study 
treatment and refrain from donating sperm during 
this period (Appendix 5).

3.3.2.
Benefit Assessment
The proposed study with GSK2983559 will be conducted in healthy participants.  No 
medical benefit will be derived by participants’ participation.  Participants will indirectly 
gain through their contribution to the process of developing new therapies in an area of 
unmet need.  
3.3.3.
Overall Benefit:Risk Conclusion
The known risks associated with GSK2983559 can be appropriately mitigated by the 
careful selection of study participants and the proposed safety monitoring procedures.  As 
such, the risk to potential participants is considered low.  Routine safety and tolerability 
will be evaluated from reported adverse events (AEs), scheduled physical examinations, 
vital sign measurements, cardiac rhythm monitoring, 12-lead ECGs, and clinical 
laboratory test results as well as continued observation by clinical staff.  
The study will be conducted in a hospital-based unit or unit with immediate access to 
hospital facilities for the treatment of medical emergencies.  The in-house periods as 
detailed in the SoA will allow for continuous medical monitoring for all participants 
following the first dose in each treatment group.  Participants will only be discharged 
from the unit 48 hours after their last dose of GSK2983559 if the Investigator deems it 
safe to do so.
Taking into account the measures taken to minimize risk to participants participating in 
this study, the potential risks identified in association with GSK2983559 are justified by 
the anticipated benefits that may be afforded by the future development of a new therapy 
in an area of unmet need.

STUDY DESIGN
5.1.
Overall Design
This study will be a randomised, double-blind (sponsor open), placebo-controlled, two-
part study of oral administration of GSK2983559 in healthy participants. Part A will be a 
single ascending dose crossover design in two separate cohorts of participants (Cohorts 1 
and 2). In addition to the crossover treatment periods, subjects in Cohort 2 will participate 
in an additional treatment period and receive open-label GSK2983559 under fed 
conditions. Part B will be a repeat dose design in up to 4 cohorts of participants (Cohorts 
3-6). This study is planned to include approximately 62 participants.
Parts A and B of this study will be double-blind with respect to participants, investigator 
and site staff (with the exception of the site pharmacist). Sponsor open refers only to 
members of the Dose Escalation Committee (DEC) at defined meetings. Members and 
requirements are provided in a Dose Escalation Charter. 

Part A – single ascending doses, randomized, placebo controlled, crossover.
Part A plans to explore up to 9 single ascending dose levels. This will be 2 cohorts, 
Cohort 1 (standard capsule) and Cohort 2 (enteric capsule), of 10 and 12 healthy 
participants, respectively. The total duration of Part A of the study for each participant, 
including screening and follow-up, is approximately 11 weeks.

25
-
Cohort 1: 5-way crossover design with the standard capsule. Each participant will 
receive single ascending oral doses of either GSK2983559 or placebo in a 4:1 ratio 
according to the randomisation schedule, in study periods 1 to 5, in a blinded manner.
-
Cohort 2: 4-way crossover design with the enteric capsule for single ascending dose, 
including an additional period for assessing GSK2983559 under fed conditions 
(period 5 – open-label).
During the blinded part, each participant will receive single ascending oral doses of 
either GSK2983559 or placebo in a 3:1 ratio according to the randomisation schedule, 
in study periods 1 to 4, in a blinded manner.
If dose levels 6-9 are not investigated, Cohort 2 will only be used for evaluating the 
effect of food. It will be an open-label 2-way crossover design.
-
Cohorts 1 and 2 will be dosed sequentially, incorporating sentinel participants: Cohort 
1 will complete all 5 dosing periods before Cohort 2 begins. 
-
Following completion of Cohort 1 and before starting Cohort 2, a GSK internal safety 
board (independent of DEC) will be reviewing the data.
-
Based on emerging PK data, all doses may not be investigated.
-
There will be a at least 48-hour washout period between each dose escalation step but 
the washout period may be extended depending on emerging data.
Treatment period
-
Cohort 1 (single dose) will be comprised of up to 5 study periods, each at least 4 days 
in duration with participants in-house for 3 nights (through 48 hours post-dose). 
During each treatment period, participants will be admitted to the unit the day before 
dosing and will be discharged after completion of the 48-hour post-dose assessments.
-
Cohort 2 (single dose) will be comprised of up to 4 study periods, each at least 4 days 
in duration with participants in-house for 3 nights (through 48 hours post-dose). 
During each treatment period, participants will be admitted to the unit the day before 
dosing and will be discharged after completion of the 48-hour post-dose assessments.

Sentinel dosing will be employed within each ascending dose cohort and treatment 
period (except for when investigating the food effect). On Day 1, one participant will 
receive GSK2983559 and one participant will receive matched-placebo, to evaluate 
tolerability and safety for at least 24 hours post-dose. Dosing in the remaining 8 and 
10 participants in Cohorts 1 and 2, and treatment period will occur at least 24 hours 
later after review of safety results from the initial 2 participants in a 7:1 and 4:1 ratios
(GSK2983559: placebo) for Cohorts 1 and 2, respectively
The decision to proceed to the next single dose level will be made at a DEC meeting (see 
Appendix 3: Study Governance Considerations).
Treatment sequences for Part A:
The treatment sequences for Part A are outlined below and the planned dose levels (DLs) 
are defined in Section 5.5. The dose of GSK2983559 administered with a high-fat meal 
will be a dose level already evaluated in the dose escalation part of the study and will be 
determined by DEC and based on attainment of adequate exposure and safety.

Treatment period
-
The treatment period will be 14 days. 
-
Participants will be admitted to the unit the day before dosing, will remain in the unit 
overnight, and will be discharged following completion of the assessments on Day 
16, provided there are no safety concerns. 
-
Participants will have a follow-up visit at least 7 days or 5 half-lives (as determined 
from Part A PK data) whichever is longer, and no greater than 14 days after last study 
drug administration. If warranted, additional follow-up visits may be scheduled.
Dosing
-
Once-daily (QD) dosing is planned in Part B, but twice-daily dosing (BID) may be 
considered based upon the PK profile as well as the safety and tolerability observed in 
Part A.
-
Sentinel dosing will be employed within each cohort.  On Day 1, one participant will 
receive GSK2983559 and one participant will receive matched-placebo, both 
participants will be dosed to steady state (approximately Day 2 minimum based on 
PK predictions from Part A). Dosing in the remaining 8 participants in each cohort 
will occur after review of safety results from the initial 2 participants in a 7:1 ratio 
(GSK2983559: placebo).
The decision on the dose level of GSK2983559 to be administered in Cohort 3 will be 
made at a DEC meeting based on all safety, tolerability, and PK data accumulated from 
Part A of the study. The decision to proceed to the next single dose level will be made at 
a DEC meeting (see Appendix 3: Study Governance Considerations).

Scientific Rationale for Study Design
The current study described herein has been designed to address regulatory guidance for 
FTIH studies and in particular General Considerations for Clinical Trials [The 
International Council for Harmonisation of Technical Requirements for Pharmaceuticals 
for Human Use (ICH) E8/ Committee For Proprietary Medicinal Products 
(CPMP)/ICH/291/95] and Guideline on Strategies to Identify and Mitigate Risk for First-
in-Human 
Clinical 
Trials 
with 
Investigational 
Medical 
Products 
[EMEA/CHMP/SWP/28367/07] as well as pre-clinical findings for GSK2983559, 
contributing to the frequency, type and duration of safety assessment and monitoring 
during treatment periods during each cohort.
The sequential design of the single dose components (Part A) and estimated 5-hour half-
life (t1/2) will allow for dose escalation to occur after less than 6 days of washout. The 
predicted time for GSK2668176 plasma concentrations to reach the lower limit of 
quantification (LLOQ, 0.20 ng/ml) after dosing for the highest selected dose (see Section 
5.5 below) was 3 days. This will allow any adjustment needed based on emerging safety, 
tolerability, and PK information. The randomised crossover design was chosen to allow 
for treatment comparison between and within participants. Further, a food-effect 
evaluation is planned to support progression into patient studies.

In Part B, the 14-day dosing will provide exposure to PK steady state and will also be 
informative of the likely safety and tolerability in future longer studies.
5.5.
Dose Justification
5.5.1.
Human PK prediction
GSK2983559 is a phosphate ester pro-drug which is converted into GSK2668176 (active 
moiety) primarily by the alkaline phosphatase present in the intestinal lumen. The 
systemic exposure of the prodrug GSK2983559 is predicted to be <2% in humans and is 
considered to have a negligible contribution to clinical effect and is not considered 
relevant for human dose determination.
The human pharmacokinetic (PK) profiles as well as parameters of parent drug 
GSK2668176 following oral dosing of prodrug GSK2983559 were predicted using in 
vitro to in vivo extrapolation and allometric scaling. The predicted human mean 
absorption rate constant (0.85 1/h), clearance (0.426 L/h/Kg), volume of distribution (2.8 
L/Kg), half-life (4.6 hours) and bioavailability (70%) were used to determine the blood 
PK profiles for GSK2668176 following oral administration of GSK2983559. 
As the exposures observed in preclinical species were in plasma, the predicted human PK 
estimates in blood were multiplied by a factor of 0.83 (blood/plasma ratio=1.2 for
GSK2668176) to give the corresponding human PK estimates in plasma for calculating 
the safety fold coverage to the no observable adverse effect limit (NOAEL).
5.5.2.
Starting dose selection for Part A
The predicted human PK parameters along with the human whole blood (HWB) ex vivo 
assay data (HWB:
muramyl dipepide
(MDP)/TNFα Inhibitory concentration 
(IC)90=86.67 ng/mL) were used for human PK/PD predictions at various human dose 
levels. The ‘Minimal Anticipated Biological Effect Level’ (MABEL) approach was used 
as the basis to define the starting dose for GSK2983559 monotherapy in the single 
ascending dose phase of the study. A starting dose of 2 mg was chosen, as maximum and 
minimum PD inhibition are predicted to be approximately 30% and 3% at the predicted 
mean Cmax and mimimum observed concentration (Cmin) (24 h) values, respectively. 
Mean Cmax and AUC(0-) values of GSK2668176 in human plasma are projected to be 
0.004 µg/mL and 0.038 µg.h/mL, respectively, for the starting dose of 2 mg 
GSK2983559; these human predicted exposures are 753- and 708-fold lower than plasma 
Cmax and area under the concentration-time curve from time zero to 24 hours post first 
dose [AUC(0-24)] values at the NOAEL(60 mg/kg/day) in the six-week female rat 
preclinical toxicological study and 1870 and 1338-fold lower at the NOAEL 
(120mg/kg/day) in the six-week minipig preclinical toxicology study. In addition, the 
predicted mean Cmax at the 2 mg/day human dose is 106-fold lower compared to Cmax at 
the no observable effect limit (NOEL)
(1 mg/kg) in the rat Irwin studies 
(neurobehavioural studies in male rats). Thus, a starting dose of 2 mg in human provides 
sufficient safety margins against the preclinical toxicological findings to ensure the safety 
of study participants.

5.5.3.
Anticipated efficacious dose
The level of inhibition of ex-vivo cytokine response required for efficacy is not known.
An efficacious dose may be anticipated with  90% inhibition of cytokine response at 
trough concentration measured at the end of a dosing interval at steady state (Ctrough)
(HWB:MDP/TNFα IC90=86.67 ng/mL). A dose of 800 mg QD was originally predicted 
to provide a mean inhibition of 90% at Ctrough for 24 hours.  A similar level of inhibition 
was predicted to be achieved with 100 mg BID dosing (total dose 200 mg/day). 
Accounting for between subject variability in PK and PD (assuming 30% between-
subject variability on apparent total clearance of the drug from plasma after oral 
administration (CL/F)], V/F, absorption rate constant (Ka) and IC50 for simulations), a 
dose of 400 mg BID (total daily dose of 800 mg) was predicted to be required for 90% 
inhibition at Ctrough in approximately 90% of population.  Based on emerging 
GSK2668176 pharmacokinetic data from the current study, a dose of 400 mg QD is 
predicted to provide a mean inhibition of 90% at Ctrough for 24 hours.  Accounting for 
between subject variability in PK, a dose of 200 mg BID (total daily dose of 400 mg) is 
predicted to be required for 90% inhibition at Ctrough in approximately 90% of population.
5.5.4.
Top dose selection for Part A
The expected exposure from the anticipated efficacious dose of 200 mg BID would have 
to be tested in the single ascending dose part, thus, requiring the need for evaluating 400 
mg. Since the level of inhibition of ex-vivo cytokine response required for efficacy is not 
known, doses that produce higher than 90% cytokine inhibition should be evaluated in 
the future efficacy dose ranging study. With the highest planned single dose of 600 mg, 
predicted plasma Cmax (1.84 µg/mL) and AUC(0-) (17.3 µg.h/mL) values are expected to 
provide >1.6-fold and >1.6-fold safety margin over the female rat NOAEL in the 6-week 
study for Cmax and area under the concentation-time curve (AUC), respectively and 4.1-
fold for Cmax and 2.94-fold for AUC in minipigs. If exposure levels are lower than 
expected, doses higher than 600 mg may be evaluated. The progression from one dose 
level to another will be made based on the assessment of the available data from previous 
dose levels by the Dose Escalation Committee (See Appendix 3: Study Governance 
Considerations). Table 7 lists the predicted NOAEL cover for GSK2668176 at various 
planned GSK2983559 doses in the FTIH study.

Dose selection for Food Effect
An assessment of the effect of food on the exposure to GSK2983559/ GSK2668176 will 
be incorporated into the single dose part of the study (Part A). The food effect was 
predicted to be non-significant up to 300 mg dose using GastroPlus (physiologically 
based pharmacokinetic modelling (PBPK) modeling platform). Fed State Simulated 
Intestinal Fluid / Fasted State Simulated Intestinal Fluid (FeSSIF / FaSSIF) ratio for 
GSK2983559 is 1.5; therefore, a 50% increase in exposure could be anticipated relative 
to fasting state exposure. The dose to be administered with food will be selected such 
that, if there were a 50% increase in exposure it would be predicted to be within the 
safety margins.
Dose selection for Part B
Part B (repeat dose) of the study will be initiated after completion of Part A. Dose 
selection will be based upon consideration of available safety, tolerability and PK data 
from Part A and/or preceding repeat dose cohorts in Part B. Based on the observed half-
life of approximately 8 h GSK2668176 in humans, minimum accumulation is anticipated 
after BID dosing.  The dose of GSK2983559, noted as X, is anticipated to provide 90% 
inhibition at Ctrough levels of GSK2668176 in 50% of the population and will be re-
estimated based on the PK and PD data collected in the early doses in Part A. The initial 


2017N322016_02
CONFIDENTIAL
205021
33
dose in Part B (Cohort 3, repeat dose) will be approximately half X. Dose escalation in 
the repeat dose part of the study will not exceed 2-fold between cohorts and will be 
driven by safety and PK stopping criteria (see Section 8). In addition, a dose will not be 
assessed as a repeat dose until the anticipated steady-state exposure (Cmax and AUC(0-) on 
Day 14) for that dose have been evaluated and shown not to have met safety stopping 
criteria in the single dose portion of the study (Part A). Based on current PK predictions a 
dose of 200 mg BID dosing regimen is predicted to provide 90% inhibition in 
approximately 90% of subjects. Dose levels higher than this may be explored in order to 
evaluate dose response in future phase 2 dose ranging study provided that exposure levels 
for that dose has been previously evaluated in Part A of the study.
5.5.5.
Assessment and control of 5-ABT
5-amino-benzothiazole (5-ABT), an impurity in the GSK2983559 drug substance (3-6 
parts per million (ppm) [m.2.1.S.3.2 Impurities in chemistry, manufacturing and controls 
(CMC) investigational medicinal product dossier (IMPD)], was found to be mutagenic in 
an in vitro Ames assay. In addition, 5-ABT was formed from GSK2668176 in bio
relevant media (pH 6.5 and pH 8 in FaSSIF and FeSSIF conditions), suggesting that a 
theoretical risk exists for its formation at physiological pH.  According to ICH M7 
guidance for the assessment and control of deoxyribonucleic acid (DNA) reactive 
(mutagenic) impurities in pharmaceuticals to limit potential carcinogenic risk, 5-ABT is 
classified as a Class 2 hazard (i.e. known mutagen with unknown carcinogenic potential) 
and must be controlled at or below the Threshold of Toxicological Concern (TTC) of 120 
µg/day considering the duration of treatment of ≤ 1 month..
5-ABT is not predicted to be a metabolite, and has not been observed as a metabolite in in 
vitro hepatocyte or S9 incubations. Real time analysis of plasma samples from FTIH for 
5-ABT and its metabolite N-acetyl 5-ABT will be performed to monitor exposure to 5-
ABT in healthy volunteers.
Quantifiable concentrations of 5-ABT were observed below the stopping criteria 
(combined Cmax of 5-ABT  and NAc-5-ABT of 3 ng/mL) in 4 out of 8 subjects treated 
with GSK2983559 in Cohort 1 at the 100-mg dose level.  The maximum observed 5-ABT 
concentration was 1.25 ng/mL.  An enteric capsule [Hydroxypropylmethyl Cellulose
Acetate Succinate (HPMCAS)] will be used starting in Cohort 2 and carry through to 
Cohort 6 to determine if this formulation will minimize the gastric conversion of drug 
substance to 5-ABT.  The disintergration of an enteric capsule is pH dependent and is 
expected to avoid hydrolysis of the active pharmaceutical ingredient (API) to 5-ABT in 
the acidic environment of the stomach and release API in a higher pH environment in the 
proximal small intestine.

9. Average QTc > 450 msec 
NOTES:
a.
The QTc is the QT interval corrected for heart rate according to Bazett’s
formula (QTcB), Fridericia’s formula (QTcF), and/or another method,
machine- read or manually over-read.
b. The specific formula that will be used to determine eligibility and
discontinuation for an individual participant should be determined prior to
initiation of the study. In other words, several different formulae cannot be
used to calculate the QTc for an individual participant and then the lowest
QTc value used to include or discontinue the participant from the trial.
For purposes of data analysis, QTcB, QTcF, another QT correction formula, or a
composite of available values of QTc will be used as specified in the Reporting and
Analysis Plan (RAP).

Method of Treatment Assignment
At screening a unique number (case report form [CRF] number) will be assigned to any 
participant who has at least one Screening procedure performed, other than signed
informed consent. The unique number will be used to identify individual participants 
during the course of the study.
Participants who meet the screening eligibility criteria will be randomised to a treatment 
group through an Interactive Response Technology (IRT). The IRT will confirm the 
participants CRF number and provide the randomisation number, where:

A randomisation number will be assigned from a randomisation schedule 
generated by Clinical Statistics, prior to the start of the study, using validated 
internal software. Once assigned, this number must not be reassigned to any other 
participant in the study.
The randomisation is centrally controlled by the IRT.
Part A
Within Cohort 1, participants will be assigned to one of 5 dosing sequences in a 1:1:1:1:1
ratio. 
Within Cohort 2, participants will be assigned to one of up to 4 dosing sequences in a 
1:1:1:1 ratio.

Blinding
This will be a double blind (sponsor open) study with respect to allocation of 
GSK2983559 or placebo to participants. The food effect part of the study will be open-
label. 
The following will apply:

The investigator or treating physician may unblind a participant’s treatment 
assignment only in the case of an emergency OR in the event of a serious 
medical condition when knowledge of the study treatment is essential for the 
appropriate clinical management or welfare of the participant as judged by the 
investigator.

Investigators have direct access to the participant’s individual study treatment.

It is preferred (but not required) that the investigator first contacts the Medical 
Monitor or appropriate GSK study personnel to discuss options before unblinding 
the participant’s treatment assignment.

If GSK personnel are not contacted before the unblinding, the investigator must 
notify GSK as soon as possible after unblinding, but without revealing the 
treatment assignment of the unblinded participant, unless that information is 
important for the safety of participants currently in the study.

The date and reason for the unblinding must be fully documented in the CRF.

A participant will be withdrawn if the participant’s treatment code is unblinded
by
the investigator
or
treating
physician.
The
primary
reason
for
discontinuation (the event or condition which led to the unblinding) will be 
recorded in the CRF.

GSK’s Global Clinical Safety and Pharmacovigilance (GCSP) staff may unblind 
the treatment assignment for any participant with an SAE. If the SAE requires
that an expedited regulatory report be sent to one or more regulatory agencies, a
copy of the report, identifying the participant’s treatment assignment, may be sent
to investigators in accordance with local regulations and/or GSK policy.

Sponsor open refers only to the DEC members involved in the review of the
unblinded safety data on an as required basis and at the dose escalation meetings,


2017N322016_02
CONFIDENTIAL
205021
43
where no-one outside of this committee will be unblinded to the study data.
Further details of how this will be managed are included in Appendix 3.
7.5.
Preparation/Handling/Storage/Accountability

The investigator or designee must confirm appropriate temperature conditions have 
been maintained during transit for all study treatment received and any discrepancies 
are reported and resolved before use of the study treatment.

Only participants enrolled in the study may receive study treatment and only 
authorized site staff may supply or administer study treatment. All study treatments 
must be stored in a secure, environmentally controlled, and monitored (manual or 
automated) area in accordance with the labeled storage conditions with access limited 
to the investigator and authorized site staff.

The investigator, institution, or the head of the medical institution (where applicable) 
is responsible for study treatment accountability, reconciliation, and record 
maintenance (i.e., receipt, reconciliation, and final disposition records).

Further guidance and information for the final disposition of unused study treatment 
are provided in the Study Reference Manual.

Under normal conditions of handling and administration, study treatment is not 
expected to pose significant safety risks to site staff.  

A Material Safety Data Sheet (MSDS)/equivalent document describing occupational 
hazards and recommended handling precautions either will be provided to the 
investigator, where this is required by local laws, or is available upon request from 
GSK.
7.6.
Treatment Compliance

When participants are dosed at the site, they will receive study treatment directly 
from the investigator or designee, under medical supervision.  The date and time of 
each dose administered in the clinic will be recorded in the source documents.  The 
dose of study treatment and study participant identification will be confirmed at the 
time of dosing by a member of the study site staff other than the person 
administering the study treatment.  Study site personnel will examine each 
participant’s mouth to ensure that the study treatment was ingested.
7.7.
Concomitant Therapy
Any medication or vaccine (including over-the-counter or prescription medicines, 
vitamins, and/or herbal supplements) that the participant is receiving at the time of 
enrollment or receives during the study must be recorded along with:

reason for use

dates of administration including start and end dates

dosage information including dose and frequency


2017N322016_02
CONFIDENTIAL
205021
44
The Medical Monitor should be contacted if there are any questions regarding 
concomitant or prior therapy.
Participants must abstain from taking prescription or nonprescription drugs (including 
vitamins and dietary or herbal supplements) within 7 days (or 14 days if the drug is a 
potential enzyme inducer) or 5 half-lives (whichever is longer) before the start of study 
treatment until completion of the follow-up visit, unless, in the opinion of the investigator 
and sponsor, the medication will not interfere with the study. 
Paracetamol, at doses of 2 grams/day, is permitted for use any time during the study. 
Other concomitant medication may be considered on a case-by-case basis by the 
Investigator in consultation with the Medical Monitor if required.
7.8.
Treatment after the End of the Study
Participants will not receive any additional treatment from GSK, or with GSK2983559, 
after the completion of the study because only healthy participants are eligible for study 
participation.
8.
DOSE ESCALATION CRITERIA
8.1.
PK criteria for GSK2668176
Due to the non-tolerated high dose of 420 mg/kg/day GSK2983559 in minipigs, the PK 
stopping criteria are based on AUC(0-24) and Cmax values at 1/3rd of the NOAEL of 120 
mg/kg/day GSK2983559 (GSK2668176 AUC(0-24) 50.9 µg*h/mL, Cmax 7.5 µg/mL).  
The decision to proceed to the next dose level of GSK2983559 in each part of this study 
will be made by the DEC, based on safety, tolerability, and preliminary PK data obtained 
(through at least 24 hours post dose) with at least 4 participants having received active 
treatment (GSK2983559) at the current dose level.  The actual doses to be administered 
may be adjusted based on safety, tolerability and preliminary PK data at previous dose 
levels; these dose adjustments may involve either an increase or a decrease in the planned 
dose, but will not exceed PK criteria.  Planned doses may also be repeated.
It is planned that the predicted human mean GSK2668176 AUC(0 24) or Cmax values will 
not exceed the mean GSK2668176 AUC(0-24) and Cmax values observed at one third of the 
NOAEL in minipig (16.94 µg*h/mL and 2.5 µg/mL, respectively).  In addition, the 
predicted human maximum AUC(0 24) or Cmax values will not exceed the maximum 
observed AUC(0 24) and Cmax values at one third NOAEL (21.6 µg*h/mL and 3.25 
µg/mL).
8.2.
PK criteria for 5-ABT and NAc-5-ABT
The drug product contains an impurity (5-ABT) known to be mutagenic (with unknown 
carcinogenic potential) that is controlled in drug production to assure its level is below a 
Threshold of Toxicological Concern (TTC) per the ICH M7 guideline.  However, 
because of a possibility for 5-ABT to be formed in the body, monitoring for 5-ABT (and 
its metabolite, NAc-5-ABT) in blood plasma will be undertaken with application of the 


2017N322016_02
CONFIDENTIAL
205021
45
same TTC (120 µg), which translates to a plasma concentration of 3 ng/mL under the 
assumption that the mutagenic impurity distributes into a volume equal to total body 
water of 42L. Based on this information, if in any individual the Cmax of combined 
concentration of 5-ABT and NAc-5-ABT (in ng/mL equivalents 5-ABT/mL) is > 3 
ng/mL, it will suggest the TTC level of 120 µg has been reached and further dose-
escalation will be stopped. During dose escalation, progression to the next dose level will 
be guided by the criteria where the maximum predicted 5-ABT amount for the next dose 
will not exceed the TTC of 120 µg.
8.3.
Safety criteria
The Principal Investigator and the GSK Medical Monitor will review the following and 
study dosing will be stopped if any of these criteria is met:

One (1) or more participants experience a serious adverse event (SAE) which has a 
reasonable possibility of relation to study drug.

Two (2) or more participants experience a severe or clinically significant non-serious 
adverse event (based upon investigator judgment) which has a reasonable possibility 
of relation to study drug.

Two (2) or more participants in a Part A cohort or 3 or more participants in a Part B 
cohort experience the same adverse event of moderate severity which has a 
reasonable possibility of relation to study drug.

Consistent Common Terminology Criteria for Adverse Events (CTCAE) Nervous 
System adverse events of any grade occur across participants that have a reasonable 
possibility of relation to study drug.
If dosing is halted and if deemed acceptable by GSK internal safety review to proceed 
with or modify dose escalation to further characterize the safety profile, a formal request 
with appropriate data and substantial amendment will be submitted to Medicines and 
Healthcare Products Regulatory Agency (MHRA) for approval.
9.
DISCONTINUATION CRITERIA
9.1.
Individual Safety Stopping Criteria

If a participant experiences a serious or severe clinically significant AE that in the 
clinical judgement of the Investigator, after consultation with the Medical 
Monitor, is possibly, probably or definitely related to investigational product.

The participant initiates treatment with any prohibited medications.

The participant develops a serious opportunistic or atypical infection.

If any of the liver chemistry stopping criteria or QTc stopping criteria are met.

The participant experiences any signs of suicidal ideation or behaviour.

9.2.
Neurological/psychiatric Stopping Criteria
The CNS observations in the first good laboratory practice (GLP) acute neurobehavioural 
study in rats were found to be present at all single doses.  The same findings were not 
observed in a second study with overlapping doses.  The CTCAE Nervous System is a 
monitoring tool which provides the Principal Investigator the appropriate guidance for 
grading of a neurological event.  The significance of any neurological event experienced 
by a participant will be determined based on clinical judgment, characteristics of the 
event and/or based upon changes from a baseline assessment.
The Principal Investigator and the GSK Medical Monitor will review all neurological
events utilizing the CTCAE Nervous System criteria
A participant will be withdrawn from the study if any of these criteria is met:

A Grade 3 or greater CTCAE Nervous System finding (see SRM) is observed or a 
significant neurologic change from a participant’s baseline physical examination is 
observed.

Any adverse event included in the CTCAE for Nervous System, which is also 
considered to be clinically significant by the Principal Investigator, will be reviewed 
for potential participant withdrawal.
9.3.
Liver Chemistry Stopping Criteria
Liver chemistry stopping and increased monitoring criteria have been designed to 
assure participant safety and evaluate liver event etiology (in alignment with the food 
and drug administration [FDA] premarketing clinical liver safety guidance). These 
protocol guidelines are in alignment with FDA premarketing clinical liver safety 
guidance:
http://www.fda.gov/downloads/Drugs/GuidanceComplianceRegulatoryInformation/Guid
ances/UCM174090.pdf.
Discontinuation of study treatment for abnormal liver tests should be considered by the 
investigator when a participant meets one of the conditions outlined in the algorithm or if 
the investigator believes that it is in the best interest of the participant. 
Study treatment will be discontinued for a participant if liver chemistry stopping criteria 
are met:

9.3.1.
Study Treatment Restart or Rechallenge
During part B, study treatment restart or rechallenge after liver chemistry stopping 
criteria are met by any participant in this study is not allowed.
9.4.
QTc Stopping Criteria

The same QT correction formula must be used for each individual participant to 
determine eligibility for and discontinuation from the study.  This formula may not 
be changed or substituted once the participant has been enrolled.

For example, if a participant is eligible for the protocol based on QTcB, then 
QTcB must be used for discontinuation of this individual participant as well.

Once the QT correction formula has been chosen for a participant’s eligibility, 
the same formula must continue to be used for that participant for all QTc data 
being collected for data analysis.  Safety ECGs and other non-protocol specified 
ECGs are an exception.  

The QTc should be based on single or averaged QTc values of triplicate 
electrocardiograms 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 treatment.


QTc > 500 msec,

Change from baseline: QTc >60 msec increase
See the SoA for data to be collected at the time of treatment discontinuation and follow-
up and for any further evaluations that need to be completed.
9.5.
Withdrawal from the Study

A participant may withdraw from the study at any time at his/her own request, 
or may be withdrawn at any time at the discretion of the investigator for safety, 
behavioral, compliance or administrative reasons.

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.

Refer to the SoA for data to be collected at the time of study discontinuation and 
follow-up and for any further evaluations that need to be completed.
9.6.
Lost to Follow Up
A participant will be considered lost to follow-up if he or she 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:

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/she will be considered to 
have withdrawn from the study with a primary reason of lost to follow-up. 
10.
STUDY ASSESSMENTS AND PROCEDURES

Study procedures and their timing are summarized in the SoA. 

Protocol waivers or exemptions are not allowed 


2017N322016_02
CONFIDENTIAL
205021
49

Immediate safety concerns should be discussed with the sponsor immediately upon 
occurrence or awareness to determine if the participant should continue or 
discontinue study treatment.

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 (eg, 
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 participant over the duration of 
the study, including any extra assessments that may be required, will not exceed 500
mL.

Repeat or unscheduled samples may be taken for safety reasons or for technical 
issues with the samples.
10.1.
Adverse Events
The definitions of an AE or SAE can be found in Appendix 4.
The investigator and any 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 treatment or the study, 
or that caused the participant to discontinue the study (see Section 9). 
10.1.1.
Time Period and Frequency for Collecting AE and SAE 
Information

All SAEs will be collected from the start of treatment until the follow-up visit at 
the time points specified in the SoA (Section 2).  However, any SAEs assessed 
as related to study participation (e.g., study treatment, protocol-mandated 
procedures, invasive tests, or change in existing therapy) or related to a GSK 
product will be recorded from the time a subject consents to participate in the 
study.

All AEs will be collected from the start of treatment until the follow-up visit at 
the time points specified in the SoA (Section 2).

Medical occurrences that begin before the start of study treatment but after 
obtaining informed consent will be recorded on the Medical History/Current 
Medical Conditions section of the case report form (CRF) not the AE section.

All SAEs will be recorded and reported to the sponsor or designee within 24 
hours after becoming aware of the event, as indicated in Appendix 4. The 


2017N322016_02
CONFIDENTIAL
205021
50
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 in former study 
participants. However, if the investigator learns of any SAE, including a death, 
at any time after a participant has been discharged from the study, and he/she 
considers the event to be reasonably related to the study treatment or study 
participation, the investigator must promptly notify the sponsor.

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 4.
10.1.2.
Method of Detecting AEs and SAEs
Care will be taken not to introduce bias when detecting AE and/or SAE. Open-ended and 
non-leading verbal questioning of the participant is the preferred method to inquire about 
AE occurrence. 
10.1.3.
Follow-up of AEs and SAEs
After the initial AE/SAE report, the investigator is required to proactively follow each 
participant at subsequent visits/contacts. All SAEs, will be followed until the event is 
resolved, stabilized, otherwise explained, or the participant is lost to follow-up (as 
defined in Section 9.6). Further information on follow-up procedures is given in 
Appendix 4.
10.1.4.
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 
participants and the safety of a study treatment 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 treatment 
under clinical investigation. The sponsor will comply with country-specific 
regulatory requirements relating to safety reporting to the regulatory authority, 
Institutional Review Boards (IRB)/Independent Ethics Committees (IEC), 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 Investigator’s Brochure and 
will notify the institutional
review board/independent ethics committee 
(IRB/IEC), if appropriate according to local requirements.

10.1.5.
Pregnancy

Details of all pregnancies in female partners of male participants will be collected 
after the start of study treatment and until 30 days after the last dose.

If a pregnancy is reported, the investigator should inform GSK within 24 hours of 
learning of the pregnancy and should follow the procedures outlined in Section 13.5.

Abnormal pregnancy outcomes (e.g., spontaneous abortion, fetal death, stillbirth, 
congenital anomalies, ectopic pregnancy) are considered SAE.
10.2.
Treatment of Overdose
GSK does not recommend specific treatment for an overdose.  The investigator will use 
clinical judgement to treat an overdose as and when they are made aware of this.
In the event of an overdose, the investigator should:
1.
Contact the Medical Monitor immediately.
2.
Closely monitor the participant for AE/SAE and laboratory abnormalities until 
GSK2983559 can no longer be detected systemically (at least 48hours).
3.
Obtain a plasma sample for PK analysis 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 
participant.
10.3.
Safety Assessments
Planned time points for all safety assessments are provided in the SoA.
10.3.1.
Physical Examinations

A full physical examination will include, at a minimum, assessments of the 
Skin, Cardiovascular, Respiratory, and Gastrointestinal systems. Height and 
weight will also be measured and recorded.

A brief physical examination will include, at a minimum, assessments of the 
skin, lungs, cardiovascular system, and abdomen (liver and spleen).

Investigators should pay special attention to clinical signs related to previous 
serious illnesses.
10.3.2.
Neurological Exams
Neurological examination will include, at a minimum, assessment of: mental status, gait, 
balance, coordination, cranial nerves, motor power, reflexes, and sensory system (light 


2017N322016_02

52
touch and pain). Assessments will be standardized across all scheduled time points (see 
SoA).  Significant changes from the baseline or any clinically significant changes will be 
noted as part of further scheduled examinations or unscheduled examinations (if needed).  
Clinically significant abnormalities or changes in status from baseline will be:

entered as an adverse event,

may trigger increased monitoring of the subject(s),

may result in withdrawal of the subject (see Section 9.2),

may result in referral to a specialist.
10.3.3.
Vital Signs

Vital signs will be measured in a semi-supine position after 5 minutes rest in a 
quiet setting without distractions (e.g., television, cell phones) and will include 
temperature, systolic and diastolic blood pressure, and pulse and respiratory rate.

In Part A and Part B on Day 1 vital signs (to be taken before blood collection for 
laboratory tests) will consist of triplicate pulse and blood pressure measurements
only (3 consecutive blood pressure readings will be recorded at intervals of at 
least 1 minute). All 3 readings will be recorded on the CRF.
10.3.4.
Electrocardiograms

Triplicate OR 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 QTc intervals. Refer to Section 9.4 for QTc withdrawal criteria 
and additional QTc readings that may be necessary.

At each time point at which triplicate ECG are required, 3 individual ECG 
tracings should be obtained as closely as possible in succession, but no more
than 2 minutes apart. The full set of triplicates should be completed in less than 
4 minutes.

Continuous cardiac telemetry will be performed at time points indicated in the 
SoA (Section 2).  Full disclosures will be reviewed in detail and the review 
maintained as part of the subject’s source documents.

Holter monitoring will be performed at screening only.  This 24-hour Holter will 
be performed to eliminate participants with non-clinically overt cardiac 
arrhythmias.
10.3.5.
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 AE 


2017N322016_02

53
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 participant'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 etiology 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.
10.4.
Pharmacokinetics
10.4.1.
Blood Sample Collection
Blood will be collected into ethylenediaminetetraacetic acid (EDTA) tubes and processed 
to plasma for PK analysis of GSK2983559, GSK2668176, 5ABT and NAc-5ABT at the 
time points indicated in Section 2, SoA Tables. The actual date and time (24-hour clock 
time) of each blood sample collection will be recorded. The timing of PK samples may be 
altered and/or PK samples may be obtained at additional time points to ensure thorough 
PK monitoring.  
In Part B on Day 1 and Day 14, at each sampling time point an additional blood sample 
will be collected for metabolite profiling. 
Details of blood sample collection, processing, storage and shipping procedures are 
provided in the SRM. 
10.4.2.
Plasma Sample Analysis
Plasma analysis will be performed at a bioanalytical site (to be detailed in the SRM) 
under the control of Platform Technology and Science In Vitro/In Vivo Translation (PTS 
IVIVT) and Third Party Resource, GlaxoSmithKline. Concentrations of GSK2983559, 
GSK2668176, 5ABT and NAc-5ABT in plasma samples will be determined using the 
currently approved bioanalytical methodology. Raw data will be archived at the 
bioanalytical site (detailed in the SRM). 
Once the plasma sample has been analysed for GSK2983559, GSK2668176, 5ABT and 
NAc-5ABT, any remaining plasma sample may be analysed for other compound-related 
material and the results may be reported under a separate PTS-Global Spectroscopy, 
GlaxoSmithKline protocol.
Drug concentration information that may unblind the study will not be reported to 
investigative sites or blinded personnel until the study has been unblinded.

10.4.3.
Urine sample collection and analysis
Urine samples for analysis of GSK2983559 and GSK2669176 as well as any metabolites 
will be collected at the time points listed in Section 2, SoA Table.
Prior to dosing on Day 1, each subject will be instructed to void their bladder and no 
more than 40 mL of this urine sample will be retained as a control. Urine collection time 
points listed in the SoA table will begin immediately following dose administration (0 to 
24 hours). The time will be recorded for each urine sample collected as well as the 24-
hour volume of urine for each subject. In Part A only, urine obtained at the highest dose 
reached will be shipped to GSK. Results will be reported under a separate PTS-Global 
Spectroscopy, GlaxoSmithKline protocol. Processing, storage and shipping procedures 
are provided in the Study Reference Manual (SRM).
10.5.
Exploratory Pharmacodynamics and Target Engagement
Blood samples will also be collected at the time points indicated in Section 2 SOA. The 
actual date and time of these collections will be recorded. All procedures will be 
performed at the site.
10.6.
Pharmacodynamic Samples
For this assay 1 mL of blood will be drawn into TruCulture tubes containing a 
standardized amount of the NOD2 agonist, MDP.  Following a 6 hr incubation at 37°C, 
plasma cytokines (macrophage inflammatory protein 1 alpha [MIP1α], MIP1β, and TNF) 
will be quantified using the MesoScale Discovery platform. Two pre-dose baseline 
samples will be drawn to measure the maximum intrasubject inhibition via treatment with 
a tool compound with a similar chemical structure to GSK2983559. Details of the 
collection, processing, and storage of these PD samples are provided in the SRM.
10.7.
Target Engagement (TE) Samples
Two sets of samples will be used to evaluate target engagement. (1) For ex-vivo
evaluation of TE, blood will be drawn into 2 mL sodium heparin or K2 EDTA tubes. (2) 
For post-challenge evaluation of TE, an aliquot of the residual cells will be collected 
from the Truculture PD samples (described above). Cellular lysates will be prepared form 
both sets of samples and TE will be assessed using a novel competitive binding assay. 
Details of the collection, processing and storage of these TE samples are provided in the 
SRM.
11.
STATISTICAL CONSIDERATIONS
The objectives of this study are to assess the safety and tolerability of single and repeat 
ascending doses of GSK2983559 in healthy volunteers. No formal hypotheses will be 
tested.

11.1.
Sample Size Determination
A minimum number of 18 participants (10 in cohort 1 and 8 in cohort 2) will be recruited 
into Part A, and up to 40 participants (10 in each of 4 cohorts) will be recruited into Part 
B. An additional cohort may be added to Part A of the study to allow for evaluation of 
additional dose levels or repeat an existing dose level. 
The sample size is based on feasibility considerations and no statistical techniques were 
used to calculate it. 
Safety is the primary objective of Parts A and B, where numbers of safety events are of 
interest. 
A maximum of 9 participants will receive each of the active doses in Part A or B. If 0 out 
of 9 participants with a particular safety event is observed, there is 95% certainty that the 
probability of observing a participant on active with a particular safety event will lie 
between 0.04 and 0.39.
There is no sample size re-estimation planned.

Statistical Analysis Methods
Secondary
Plasma GSK2983559 and GSK2668176, concentration-time data will be 
analysed by non-compartmental methods. Calculations will be based on the 
actual sampling times recorded during the study.
From the plasma concentration-time data, the following pharmacokinetic 
parameters will be determined, as data permit: maximum observed plasma 
concentration (Cmax), time to Cmax (tmax), area under the plasma concentration-
time curve [AUC(0-24), AUC(0-t) and AUC(0-∞)], and apparent terminal phase half-life 
(t1/2). 
Part A (single dose): Dose proportionality will be assessed by visual inspection 
of dose normalised AUC(0 ∞) [or if not available AUC(0-t)] and Cmax values 
versus dose. Analysis of these loge-transformed parameters may be carried out, 
using the power model.
Part A (food effect): The ratio of fed state to fasted state may be assessed for 
the loge-transformed parameters AUC(0-∞) [or if not available AUC(0-t)] and Cmax.
The effect of food will be assessed utilising a mixed effects model, with fed state 
(fasted or fed) as a fixed effect and participant as a random effect.
Part B: The extent of accumulation after repeat dosing, the observed 
accumulation ratio (Ro), may be determined. The plasma steady state ratio (Rs) 
and an assessment of plasma steady state across the trough concentrations may
also be made. Dose proportionality may be assessed using similar methods to 
the single dose Part A. 
For combined 5-ABT and NAc-5-ABT (corrected to 5-ABT), observed Cmax and 
Tmax will be determined using non-compartmental methods and will be 
summarised descriptively.
Further details will be included in the RAP.
11.3.3.
Other Analyses
Pharmacodynamic, and biomarker exploratory analyses will be described in the reporting 
and analysis plan. The population PK analysis and pharmacodynamic analyses will be 
presented separately from the main clinical study report (CSR).
11.3.4.
Interim Analyses
Dose escalation meetings will occur after each period in Part A and after the completion 
of 14 days dosing of each cohort in Part B. The decision to proceed to the next cohort and 
next dose strength to be studied, will be made by DEC based on assessment of safety
(e.g., AEs, clinical laboratory results, vital signs and ECG) and plasma GSK2983559 
pharmacokinetic and 5-ABT concentrations obtained in all participants at the prior dose 
level. Individual safety data (adverse events, laboratory safety tests, ECGs and vital

signs) will be reviewed. This study is double blind (sponsor open), where the participant, 
investigator and site staff will remain blinded to the treatment allocation. Sponsor open 
refers only to those members of the DEC.
Following completion of Cohort 1 (Part A) and before starting Cohort 2 (Part A), a GSK 
internal safety board (independent of DEC) will be reviewing the data.
A formal interim analysis may be performed during the study on completed cohorts in 
Part A of the study to aid internal decision making only. Only the DEC members will be 
unblinded. There will be no changes to the study design or planned number of 
participants in future cohorts as a result of this interim analysis. This analysis may 
include review of individual participant data, summaries, graphical presentations and/or 
statistical analysis.
The Reporting and Analysis Plan will describe the planned interim analysis in greater 
detail.

The Dose Escalation Committee (DEC) will make the decision to proceed to the next 
dose level of GSK2983559 at the end of each single dose and repeat dose cohort; along 
with making the decision to move into Part B of the study.
The decision will be based on:
All available safety and tolerability data from a minimum of 4 participants who 
have received a dose of GSK2983559 at the current dose level and have been 
followed for at least 48 hours post dose.
All available safety and tolerability data accumulated from preceding dose 
levels.

69
All available PK data (including levels of 5-ABT and NAc-5-ABT) from the 
current dose level for at least 4 participants who have been followed for at least 
24 hours, and from preceding doses levels. 
PK and safety stopping criteria will be strictly applied. Details of these criteria in Section 
8.
There will be an open and closed part to the dose escalation meeting. At the beginning of 
the meeting blinded data will be discussed in an open forum with the investigator in 
attendance. If required, the data will then be reviewed in an unblinded fashion by the 
unblinded members of the DEC. Members and requirements are provided in a separate 
Dose Escalation Charter.
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 multicenter 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.
Dissemination of Clinical Study Data
Data Quality Assurance

All participant data relating to the study will be recorded on printed or electronic 
CRF unless transmitted to the sponsor or designee electronically (eg, 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/IEC review, 
and regulatory agency inspections and provide direct access to source data 
documents. 

The sponsor or designee is responsible for the data management of this study 
including quality checking of the data. 

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 participants 


2017N322016_02
CONFIDENTIAL
205021
70
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 
Clinical Study Report (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. 
Source Documents

Source documents provide evidence for the existence of the participant and 
substantiate the integrity of the data collected. Source documents are filed at the 
investigator’s site.

Data reported on the CRF or entered in the electronic case report form (eCRF)
that are transcribed from source documents must be consistent with the source 
documents or the discrepancies must be explained. The investigator may need to 
request previous medical records or transfer records, depending on the study. 
Also, current medical records must be available.

A study specific source documentation list will be finalised by the sponsor 
before the start of the clinical phase of the study. The document will identify 
what data should be considered source data for this study.
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/IEC or local health authorities, the sponsor's procedures, or GCP guidelines

Inadequate recruitment of participants by the investigator


Appendix 4: Adverse Events: Definitions and Procedures for 
Recording, Evaluating, Follow-up, and Reporting
Definition of AE
AE Definition

An AE is any untoward medical occurrence in a clinical study participant, temporally 
associated with the use of a study treatment, whether or not considered related to the 
study treatment.

NOTE: An AE can therefore be any unfavorable and unintended sign (including an 
abnormal laboratory finding), symptom, or disease (new or exacerbated) temporally 
associated with the use of a study treatment.
Events Meeting the AE Definition 

Any abnormal laboratory test results (hematology, 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 treatment 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 
treatment 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 participant’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 
participant’s condition.

Medical or surgical procedure (e.g., endoscopy, appendectomy): the condition that 


2017N322016_02
CONFIDENTIAL
205021
72
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) present 
or detected at the start of the study that do not worsen.
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 
participant 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 participant 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 fulfills 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, diarrhea, influenza, 
and accidental trauma (eg, 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 


2017N322016_02
CONFIDENTIAL
205021
73
not be immediately life-threatening or result in death or hospitalization but may 
jeopardize the participant 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 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.
Recording 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 participant’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 participant identifiers, with the exception of the 
participant 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 participant, causing minimal discomfort 
and not interfering with everyday activities.

Moderate: An event that causes sufficiently 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.


2017N322016_02
CONFIDENTIAL
205021
74
Assessment of Causality

The investigator is obligated to assess the relationship between study treatment 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.

Alternative causes, such as underlying disease(s), concomitant therapy, and other 
risk factors, as well as the temporal relationship of the event to study treatment 
administration will be considered and investigated.

The investigator will also consult the Investigator’s Brochure (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 participant 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.


2017N322016_02
CONFIDENTIAL
205021
75
Reporting of SAE to GSK
SAE Reporting to GSK via Paper CRF

Facsimile transmission of the SAE paper CRF is the preferred method to transmit 
this information to the medical monitor.

In rare circumstances and in the absence of facsimile equipment, notification by 
telephone is acceptable with a copy of the SAE data collection tool sent by overnight 
mail or courier service.

Initial notification via telephone does not replace the need for the investigator to 
complete and sign the SAE CRF pages within the designated reporting time frames.

Contacts for SAE reporting can be found in Study Reference Manual.

Appendix 5: Contraceptive Guidance and Collection of 
Pregnancy Information
Definitions
Women in the following categories are not considered WOCBP
1. Premenarchal
2. Premenopausal female with ONE of the following:

Documented hysterectomy

Documented bilateral salpingectomy

Documented bilateral oophorectomy
Note:  Documentation can come from the site personnel’s: review of participant’s 
medical records, medical examination, or medical history interview.
3.
Postmenopausal female

A postmenopausal state is defined as no menses for 12 months without an 
alternative medical cause. A high follicle stimulating hormone (FSH) level in 
the postmenopausal range may be used to confirm a postmenopausal state in 
women not using hormonal contraception or hormonal replacement therapy 
(HRT). However, in the absence of 12 months of amenorrhea, a single FSH 
measurement is insufficient. 

Females on HRT and whose menopausal status is in doubt will be required to 
use one of the non-hormonal highly effective contraception methods if they wish 
to continue their HRT during the study. Otherwise, they must discontinue HRT 
to allow confirmation of postmenopausal status before study enrollment.
Contraception Guidance
Male participants

Male participants with female partners of child-bearing potential are eligible to 
participate if they agree to ONE of the following during the protocol-defined 
time frame in Section 6.1: 

Are abstinent from penile-vaginal intercourse as their usual and preferred 
lifestyle (abstinent on a long term and persistent basis) and agree to remain 
abstinent 

Agree to use a male condom plus an additional method of contraception 
with a failure rate of <1% per year as described in Table 9 when having 
penile-vaginal intercourse with a woman of childbearing potential 

Men with a pregnant or breastfeeding partner must agree to remain abstinent 
from penile-vaginal intercourse or use a male condom during each episode of 
penile penetration during the protocol-defined time frame.

Vasectomized partner 
(A vasectomized partner is a highly effective contraception method provided that the partner is 
the sole male sexual partner of the WOCBP and the absence of sperm has been confirmed. If 
not, an additional highly effective method of contraception should be used.)
Sexual abstinence 
(Sexual abstinence is considered a highly effective method only if defined as refraining from
heterosexual intercourse during the entire period of risk associated with the study drug. The
reliability of sexual abstinence needs to be evaluated in relation to the duration of the study and 
the preferred and usual lifestyle of the participant.)
NOTES: 
a.
Typical use failure rates may differ from those when used consistently and correctly. Use should be consistent 
with local regulations regarding the use of contraceptive methods for participants in clinical studies. 
b.
Hormonal contraception may be susceptible to interaction with the study drug, which may reduce the efficacy of 
the contraceptive method. In this case two highly effective methods of contraception should be utilized during the 
treatment period and for at least 90 after the last dose of study treatment

Collection of Pregnancy Information
Male participants with partners who become pregnant

Investigator will attempt to collect pregnancy information on any male participant’s 
female partner of a male study participant who becomes pregnant while participating 
in this study. This applies only to participants who receive study treatment.

After obtaining the necessary signed informed consent from the pregnant female 
partner directly, the investigator will record pregnancy information on the 
appropriate form and submit it to GSK within 24 hours of learning of the partner’s 
pregnancy. 

Partner will also be followed to determine the outcome of the pregnancy. 
Information on the status of the mother and child will be forwarded to GSK

Generally, follow-up will be no longer than 6 to 8 weeks following the estimated 
delivery date. Any termination of the pregnancy will be reported regardless of fetal 
status (presence or absence of anomalies) or indication for procedure.

Serum bilirubin fractionation should be performed if testing is available. If serum bilirubin fractionation is not 
immediately available, discontinue study treatment for that subject if ALT 3xULN and bilirubin 2xULN. 
Additionally, if serum bilirubin fractionation testing is unavailable, record presence of detectable urinary bilirubin on 
dipstick, indicating direct bilirubin elevations and suggesting liver injury. 
2.
All events of ALT 3xULN and bilirubin 2xULN (>35% direct bilirubin) or ALT 3xULN and INR>1.5, if INR 
measured, which may indicate severe liver injury (possible ‘Hy’s Law’), must be reported as an SAE (excluding 
studies of hepatic impairment or cirrhosis); INR measurement is not required and the threshold value stated will 
not apply to subjects receiving anticoagulants

SUMMARY OF KEY PROTOCOL INFORMATION
2.1.
Changes to the Protocol Defined Statistical Analysis Plan
This study was terminated during Cohort 2 of Part A. Participants in Cohort 2 received 
only 2 of 4 planned single doses.
Changes from the originally planned statistical analysis specified in the protocol are 
outlined in Table 1.

Statistical Analysis Plan
Statistical Analysis Plan
Rationale for Changes

Part A (single dose): Dose 
proportionality will be 
assessed by visual 
inspection of dose 
normalised AUC(0 ∞) [or if 
not available AUC(0-t)] and 
Cmax values versus dose. 
Analysis of these loge-
transformed parameters 
may be carried out, using 
the power model.

Summary of dose 
normalised PK parameters 
will be replaced by 
summary of PK parameters

No analyses of log-
transformed data will be 
conducted

Study terminated prior to 
full dose escalation 
completion

Part A (food effect): The 
ratio of fed state to fasted 
state may be assessed for 
the loge-transformed 
parameters AUC(0-∞) [or if 
not available AUC(0-t)] and 
Cmax. The effect of food 
will be assessed utilising a 
mixed effects model, with 
fed state (fasted or fed) as a 
fixed effect and participant 
as a random effect

No food effect summaries 
or statistical analyses

Study terminated prior to 
fed dosing period

Study Design
Overview of Study Design and Key Features – Part A Single Ascending Dose
Design
Features

Separate participants will be enrolled into both cohorts of Part A.

Cohort 1 Standard Capsule: 5-way crossover design. Each participant will 
receive single ascending oral doses of either GSK2983559 or placebo in a 
4:1 ratio according to the randomisation schedule, in study periods 1 to 5, in 
a blinded manner.

Cohort 2 Enteric Capsule: 4-way crossover design for single ascending
dose, including an additional period for assessing GSK2983559 under fed 
conditions (period 5 – open-label).

During the blinded part, each participant will receive single ascending oral 
doses of either GSK2983559 or placebo in a 3:1 ratio according to the 
randomisation schedule, in study periods 1 to 4, in a blinded manner.

Cohorts 1 and 2 will be dosed sequentially, incorporating sentinel 
participants: Cohort 1 will complete all 5 dosing periods before Cohort 2 
begins.

Following completion of Cohort 1 and before starting Cohort 2, a GSK 
internal safety board (independent of DEC) will be reviewing the data.

Based on emerging PK data, all doses may not be investigated.

There will be a at least 48-hour washout period between each dose 
escalation step but the washout period may be extended depending on 
emerging data.
Dosing

Participants will be randomised on Day 1 followed by a single oral dose of
GSK2983559

Sentinel dosing will be employed within each ascending dose cohort and treatment 
period (except for when investigating the food effect). 

On Day 1, one participant will receive GSK2983559 and one participant will receive 
matched-placebo, to evaluate tolerability and safety for at least 24 hours post-dose. 

Dosing in the remaining 8 and 10 participants in Cohorts 1 and 2, and treatment 
period will occur at least 24 hours later after review of safety results from the initial


At screening a unique number (case report form [CRF] number) will be assigned to 
any participant who has at least one Screening procedure performed, other than 
signed informed consent. The unique number will be used to identify individual 
participants during the course of the study.

Participants who meet the screening eligibility criteria will be randomised to a 
treatment group through an Interactive Response Technology (IRT). The IRT will 
confirm the participants CRF number and provide the randomisation number, 
where, a randomisation number will be assigned from a randomisation schedule 
generated by Clinical Statistics, prior to the start of the study, using validated 
internal software. Once assigned, this number must not be reassigned to any other 
participant in the study.

The randomisation is centrally controlled by the IRT.
Part A
Within Cohort 1, participants will be assigned to one of 5 dosing sequences in a 1:1:1:1:1
ratio.
Within Cohort 2, participants will be assigned to one of up to 4 dosing sequences in a 1:1:1:1 
ratio.

PLANNED ANALYSES
3.1.
Interim Analyses
Dose escalation meetings occurred after each period in Part A and were scheduled to 
occur following the completion of 14 days dosing of each cohort in Part B. The decision 
to proceed to the next cohort and next dose strength to be studied, was made by the Dose 
Escalation Committee (DEC) based on assessment of blinded safety (e.g., AEs, clinical 
laboratory results, vital signs and ECG), active moiety (GSK2668176) pharmacokinetic 
and 5-ABT concentrations obtained in all participants at the prior dose level. Individual 
safety data (adverse events, laboratory safety tests, ECGs and vital signs) was reviewed. 
This study was double blind (sponsor open), where the participant, investigator and site 
staff will remain blinded to the treatment allocation. Sponsor open refers only to those 
members of the DEC as required.
Following completion of Cohort 1: Part A and before starting Cohort 2: Part A, a GSK
internal safety board (independent of DEC) reviewed the emerging PK and safety data.
A formal interim analysis was due to be performed during the study on completed cohorts 
in Part A of the study to aid internal decision making only.  The study was terminated 
prior to completion of Part A.
3.2.
Final Analyses
The final planned primary analyses will be performed after the completion of the 
following sequential steps:
All participants have completed the study as defined in the protocol or the study is 
terminated.  
All required database cleaning activities have been completed and final database release
(DBR) and database freeze (DBF) has been declared by Data Management.
All criteria for unblinding the randomisation codes have been met. 
Randomisation codes have been distributed according to RandAll NG procedures.

Baseline Definitions

For all endpoints (except as noted in baseline definitions) the baseline value will be 
the latest pre-dose assessment with a non-missing value, including those from 
unscheduled visits. If time is not collected, Day 1 assessments are assumed to be 
taken prior to first dose and used as baseline.

For Part A, baseline definitions defined in the table are applicable to each treatment 
period.

Unless otherwise stated, if baseline data is missing no derivation will be performed 
and baseline will be set to missing. The mean of triplicate measurements at any given 
time point will be used as the value for that time point unless otherwise stated.

General
Multiple Measurements at One Analysis Time Point

Mean of the measurements will be calculated and used in any derivation of summary statistics but if 
listed, all data will be presented.

If there are two values within a time window (as per Section 11.3.1) the value closest to the target day
for that window will be used. If values are the same distance from the target, then the mean will be 
taken.

Participants having both High and Low values for Normal Ranges at any post-baseline visit for safety 
parameters will be counted in both the High and Low categories of “Any visit post-baseline” row of 
related summary tables. This will also be applicable to relevant Potential Clinical Importance summary 
tables.
Study Day

Calculated as the number of days from First Dose Date:

Ref Date = Missing              → Study Day = Missing 

Ref Date < First Dose Date → Study Day = Ref Date – First Dose Date

Ref Data ≥ First Dose Date → Study Day = Ref Date – (First Dose Date) + 1    
11.6.2.
Study Population
Treatment Compliance

Treatment compliance will be calculated based on the formula:  
Treatment Compliance = Number of Actual Doses / (Planned Treatment Duration in Days * 
Frequency)

Planned Treatment Duration is defined as 1 day in Part A in each period 
Extent of Exposure

Number of days of exposure to study drug will be calculated based on the formula:  
Duration of Exposure in Days = Treatment Stop Date – (Treatment Start Date) + 1

Participants who were randomised but did not report a treatment start date will be categorised as 
having zero days of exposure. 

The cumulative dose will be based on the formula:
Cumulative Dose = Sum of (Number of Days x Total Daily Dose)

If there are any treatment breaks during the study, exposure data will be adjusted accordingly.

Corrected QT Intervals

When not entered directly in the eCRF, corrected QT intervals by Fridericia’s (QTcF) formulas 
will be calculated, in msec, depending on the availability of other measurements.

IF RR interval (msec) is provided then missing QTcF will be derived as: 
Laboratory Parameters 

If a laboratory value which is expected to have a numeric value for summary purposes, has a non-
detectable level reported in the database, where the numeric value is missing, but typically a 
character value starting with ‘<x’ or ‘>x’ (or indicated as less than x or greater than x in the 
comment field) is present, the number of significant digits in the observed values will be used to 
determine how much to add or subtract in order to impute the corresponding numeric value. 
o
Example 1: 2 Significant Digits =  ‘< x ‘ becomes x – 0.01
o
Example 2: 1 Significant Digit   =  ‘> x’ becomes x + 0.1
o
Example 3: 0 Significant Digits = ‘< x’ becomes x – 1

Adverse 
Events

The eCRF allows for the possibility of partial dates (i.e., only month and year) to be 
recorded for AE start and end dates; that is, the day of the month may be missing. In 
such a case, the following conventions will be applied for calculating the time to onset 
and the duration of the event:
o
Missing Start Day: First of the month will be used unless this is before the start 
date of study treatment; in this case the study treatment start date will be used and 
hence the event is considered On-treatment as per Appendix 4: Study Phases
and Treatment Emergent Adverse Events.
o
Missing Stop Day: Last day of the month will be used, unless this is after the stop 
date of study treatment; in this case the study treatment stop date will be used.

Completely missing start or end dates will remain missing, with no imputation applied.
