PROTOCOL SYNOPSIS FOR STUDY 205184
Protocol Title: A single-centre, randomized, double-blind (sponsor-unblinded), placebo-
controlled study to evaluate the safety, tolerability and pharmacokinetics of GSK2982772 
in repeat oral doses in healthy subjects.
Short Title: GSK2982772 high dose safety and PK study in healthy volunteers.
Rationale: The purpose of this study is to evaluate the safety, tolerability and 
pharmacokinetics (PK) of repeat oral doses of GSK2982772 (TID and BID, if required) 
in healthy subjects. TID dosing will be administered as a 7hr, 7hr, 10hr dosing interval 
and BID as a 12hr dosing interval. 
Objectives and Endpoints:
Objective
Endpoint
Primary

To investigate the safety and tolerability of 
repeat doses of GSK2982772 in healthy 
subjects.

Adverse events.

Clinical laboratory values (clinical chemistry, 
haematology and urinalysis).

Vital sign measurements (blood pressure, 
heart rate, respiratory rate and body 
temperature).

Physical examinations.

12-Lead ECG monitoring.
Secondary

To characterise the PK profile of repeat 
doses of GSK2982772 in healthy subjects.

A 24 hr profile to be collected on Day 1 of 
Part A and Day 14 of Part B. On Day 1 of 
Part B, the PK profile will be evaluated 
following the first dose only. Derived PK 
parameters for GSK2982772, including area 
under the plasma drug concentration versus 
time curve over 24 hr (AUC(0-24)) and AUC 
over each dose interval (i.e. AUC(0-7), AUC(7-
14) and AUC(14-24) for TID and AUC(0-12) and 
AUC(12-24) for BID). Maximum observed 
plasma drug concentration (Cmax) following
each dose, time to maximum observed 
plasma drug concentration (Tmax) following 
each dose, observed trough plasma drug 
concentrations (C0, C7, C14 and C24 for TID
dosing and C0, C12 and C24 for BID dosing).

To assess the impact of food on the PK of 
repeat doses of GSK2982772 in healthy 
subjects at steady state

Derived PK parameters for GSK2982772, 
including AUC(0-7), AUC(7-14), Cmax, after 1st
dose of day and Tmax after 1st dose of day.

Type and Number of Participants:
Healthy volunteer subjects will be enrolled, such that up to approximately 12 subjects (9 
active, 3 placebo) in each Cohort (up to approximately 48 in total) complete dosing and 
critical assessments. A subject is defined to have completed the study when he/she has 
attended all study visits.
Sentinel dosing will be employed within each Cohort for both Part A and Part B of the 
study. The doses in the single-ascending dose portion of the study (Part A) will be 
staggered such that for each of the three treatment periods, on Day 1, two of the 12 
subjects will be randomized to treatment (one subject will receive GSK2982772 and one 
subject will receive matched-placebo). Assuming 2 subjects are dosed on Day 1 and 
assuming adequate safety in the judgment of the Principal Investigator (e.g., vital signs, 
ECGs, and adverse events) through approximately 24 hours after their last dose on Day 1, 
the remaining subjects may be randomized to dosing in that period. The doses in the 
repeat dose portion of the study (Part B) will be staggered such that for each treatment 
period on Day 1, two of the 12 subjects will be randomized to treatment (one subject will 
receive GSK2982772 and one subject will receive matched-placebo) and dosed for at 
least 7 days before the rest of the cohort is randomized. Assuming 2 subjects are dosed on 
Day 1 to 7 and assuming adequate safety in the judgment of the Principal Investigator 
(e.g., vital signs, ECGs, and adverse events) through approximately Day 7, the remaining 
subjects may be randomized to dosing.
If subjects prematurely discontinue the study, additional replacement subjects may be 
randomized in order to guarantee that sufficient subjects are treated with GSK2982772 at 
any given dose before escalating to the following dose. Replacement subjects will be 
assigned to the same treatment sequence (Cohort 1) or treatment (Cohorts 2-4) and start 
from the period to be replaced at the discretion of the Sponsor and in consultation with 
the Principal Investigator.
Treatment Groups and Duration:
The study duration, including screening and follow-up, is not expected to exceed 
13 weeks for Part A and 8 weeks for Part B of the study.
Study Duration – Cohort 1
Screening
Approximately 28 days.
Number of Subjects
One Cohort of 12 subjects (N=12).
Treatment Period
Cohort 1 will comprise of three treatment periods, investigating three dosing regimens. 
Each dose regimen consists of 1 day treatment duration, with subjects in house for 4
nights (through at least 48 hours post-last dose). Subjects will be admitted to the unit 
the day before dosing, will remain in the unit overnight, and will be released following 
completion of the assessments on Day 4 of each treatment period, provided there are 
no safety concerns.
Washout Period 
Will be at least 7 days between dose regimens for an individual subject.
Follow-up
At least 7 days and no greater than 14 days after last study drug administration. If 
warranted, additional follow-up visits may be scheduled.

SCHEDULE OF ACTIVITIES (SOA)
Protocol waivers or exemptions are not allowed with the exception of immediate safety 
concerns. Therefore, adherence to the study design requirements, including those 
specified in the Schedule of Activities (SoA) tables (Section 2.1 and Section 2.2), are 
essential and required for study conduct.
Supplementary study conduct information not mandated to be present in this protocol is 
provided in the Study Reference Manual (SRM). The SRM will provide the site 
personnel with administrative and detailed technical information that does not impact 
subject safety.
This section lists the procedures and parameters of each planned study assessment. The 
exact timing of each assessment is listed in the SoA tables (Section 2.1 and Section 2.2).
The following points must be noted:

If assessments are scheduled for the same nominal time, THEN the assessments 
should occur in the following order:
1. 12-Lead ECG
2. Vital Signs
3. Blood Draws
Note: The timing of the assessments should allow the blood draw to occur at the exact 
nominal time.

The timing and number of planned study assessments, including safety, 
pharmacokinetic, or other 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.

The change in timing or addition of time points for any planned study assessments 
must be documented in a Note to File, which is approved by the relevant GSK 
study team member and then archived in the study sponsor and site study files, 
but this will not constitute a protocol amendment.

No more than 500 mL of blood will be collected over the duration of the study, 
including any extra assessments that may be required.

The Institutional Review Board/Independent Ethics Committee (IRB/IEC) will be 
informed of any safety issues that require alteration of the safety monitoring 
scheme or amendment of the Informed Consent Form.
A table defining the allowed variance in timings of assessments without being considered 
a protocol deviation will be included in the SRM.

INTRODUCTION
3.1.
Study Rationale
The current study is being conducted to support administration of higher dose levels than 
initially studied in the First Time in Human (FTiH) study - 200975. The dose in the FTiH 
study was capped at 120 mg BID based on exposure margins with the no observable 
adverse effect limit (NOAEL) in the 28-day monkey toxicology study (10 mg/kg/day). 
Subsequently, a 13-week toxicity study in monkeys has completed which increased the 
NOAEL to 30 mg/kg/day which will allow for an approximate 4-fold increase in the 
safety margins, in terms of systemic exposure to GSK2982772. The current study is 
being conducted to explore administration of higher dose levels than achieved in the 
FTiH study to support subsequent Phase 2a Proof of Concept (PoC) studies and Phase 2b 
dose range studies in subjects with psoriasis (PsO), rheumatoid arthritis (RA) and 
ulcerative colitis (UC).    
3.2.
Background
GSK2982772 is a first-in-class, highly selective, small molecule inhibitor of receptor-
interacting serine/threonine protein-1 (RIP1) kinase. RIP1 is a member of the receptor-
interacting serine/threonine kinase family containing an amino-terminal kinase domain, 
an intermediate domain and a carboxy-terminal death domain. RIP1 regulates 
inflammatory signalling in response to stimuli such as tumour necrosis factor (TNF) and 
ligands of the Toll-like receptor family in both kinase-dependent and -independent 
manners [Ofengeim, 2013]. Upon binding to its receptor, tumour necrosis factor receptor-
1 (TNFR1), TNFα triggers one of three distinct cellular fates; NFκB activation, apoptosis, 
or the more recently identified programmed necrosis [Ofengeim, 2013]. In addition, 
recent studies have shown that the programmed necrosis signalling complex also 
regulates the induction of certain cytokines. Although RIP1 serves as a key decision 
checkpoint for all three of these pathways, its kinase activity is only requisite for the 
initiation of programmed necrosis and pro-inflammatory cytokine production [Berger, 
2014]. The discovery of this newly defined inflammatory, programmed necrotic pathway 
calls into question the major contributor to human disease downstream of the TNFR1. As 
such, a RIP1 kinase inhibitor represents a novel, selective mechanism for the treatment of 
inflammatory conditions such as Crohn’s Disease, Plaque Psoriasis, and Rheumatoid 
Arthritis through multiple mechanisms, including the blockade of cell death, danger 
associated molecular pattern (DAMP)-driven inflammation and pro-inflammatory 
cytokine production.

Investigational Product (IP) GSK2982772
Central Nervous System (CNS) Effects
Non-Clinical Data:
In the 4-week GLP toxicology study, CNS 
findings were observed in 2/12 monkeys which 
were administered 100 or 300 mg/kg/day. CNS 
findings included uncoordination, irregular gait, 
trembling, hunched appearance and decreased 
activity. The NOAEL for this study was 
determined at 10 mg/kg/day.
In the 13-week GLP toxicology study, there were 
no CNS findings observed in monkeys 
administered 10, 30 or 100 mg/kg/day. The 
NOAEL for this study was determined at 30 
mg/kg/day.
Clinical Data:
A FTiH study with single ascending and multiple 
ascending dose study has been performed in 67 
healthy male volunteers to date (see IB 
[GlaxoSmithKline Document Number 
2014N204126_02]). No drug-associated CNS 
adverse events (AEs) were identified and no 
Serious AEs (SAEs) were reported.
Subject Selection:
Subjects with known history of significant 
neurologic disorders including but not limited to 
progressive multiple sclerosis (MS), Amyotrophic
lateral sclerosis (ALS), Alzheimer’s and dementia 
will be excluded. 
Individuals with potentially increased 
susceptibility for neurologic effects will be 
excluded based on medical history at screening.
Subject Monitoring:
Subjects will be monitored for standard CNS-
related AEs.

Potential Risk of Clinical Significance
Summary of Data/Rationale for Risk 
Mitigation Strategy
Immunosuppression
The possibility of immunosuppression, including 
an increase in the frequency and/or severity of 
infection, may result from the intended 
pharmacologic effect of GSK2982772. This may
be enhanced in subjects taking other 
immunomodulating drugs or corticosteroids.
Clinical Data:
In the FTiH study, no SAEs were reported. One 
subject experienced an Adverse Event (AE) 
herpes zoster approximately 27 days after 
receiving his last dose with GSK2982772 or 
placebo. The blinded investigator determined this 
to be potentially drug-related.
Subject Selection:
Subjects with recurrent, chronic or active 
infections will be excluded from the study.
Subjects will be screened for TB, HIV, Hepatitis 
B and C, and excluded from the study if positive.
Investigators are expected to follow local and/or 
national guidelines with respect to vaccinations, 
including against influenza and pneumococcus.
Subject Monitoring:
Subjects will be monitored for signs of infection.
See Individual Safety Stopping Criteria for 
atypical or opportunistic infections (Section 
8.1.5).
Vaccinations
There is a theoretical risk that GSK2982772 
could decrease an individual’s immune response 
to vaccines or allow symptoms to develop 
following vaccination with a live vaccine when 
administered while on therapy.
Subject Selection:
Attenuated or live vaccines should not be 
administered to subjects from 30 days prior to 
the first dose of GSK2982772, during the study 
and for 5 half-lives plus 30 days (total 32 days) 
after GSK2982772 is discontinued.

Potential Risk of Clinical Significance
Summary of Data/Rationale for Risk 
Mitigation Strategy
If indicated, non-live vaccines (e.g. inactivated 
influenza vaccines) may be administered while 
receiving GSK2982772 based on a treating 
physician assessment of the benefit: risk (e.g., 
risk of theoretical decreased responsiveness).
Investigators will be expected to have followed 
local and/or national guidelines with respect to 
vaccinations, including against influenza and 
pneumococcus.
Respiratory
Non-clinical data:
In the single-dose Safety Cardiovascular and 
Respiratory Study in monkeys, a decrease in 
minute volume (MV) and respiratory rate was 
observed at all doses (10, 100, and 300 mg/kg).  
These findings were noted to be reversible and 
mild in severity.
In a 14-day repeat dose Safety Respiratory 
Study in monkeys, no respiratory effects on total 
pulmonary ventilation (MV) or respiratory rate 
were observed at doses of 1 or 10 mg/kg/day. 
See IB for GSK2982772 [GlaxoSmithKline 
Document Number 2014N204126_02].
Subject Monitoring:
Subjects should be monitored for standard 
respiratory-related AEs.
Vital signs will be monitored during study visits.

Potential Risk of Clinical Significance
Summary of Data/Rationale for Risk 
Mitigation Strategy
Clinical data:
In the FTiH study, repeat doses of GSK2982772 
up to 120 mg BID were administered x 14 days 
in 48 healthy male volunteers. Extensive 
respiratory monitoring with end-tidal CO2 
(ETCO2), oxygen saturation (SpO2) and 
nocturnal respiratory rate monitoring was 
performed.   No SAEs occurred, and no drug-
associated respiratory-related AEs were 
identified.
Suicidality
GSK2982772 is considered to be a CNS-active 
drug based on pre-clinical studies.
Clinical Data:
In the FTiH study, there have been some reports 
of lethargy, abnormal dreams and depressed 
mood. No events of suicidal ideation or 
behaviour or changes in behaviour were 
reported.
Subject Selection:
Subjects with a current history of Suicidal 
Ideation Behaviour (SIB) as measured using the 
Columbia Suicide Severity Rating Scale (C-
SSRS) or a history of attempted suicide will be 
excluded from the study.
Subject Monitoring:
Subjects should be monitored appropriately and 
observed closely for suicidal ideation and 
behaviour or any other unusual changes in 
behaviour.

personnel using the C-SSRS in all subjects.
Reproductive Toxicity
Non-Clinical Data:
In the rat embryofetal development study, there 
were no maternal or developmental toxicity at 
doses ≤200 mg/kg/day.
In the rabbit embryofetal development study, 
GSK2982772 was administered at doses of 0, 
10, 100, 300 or 600 mg/kg/day on gestation day 
7 to 19. No developmental toxicity was evident at 
doses up to 300 mg/kg/day.
Subject Selection:
Male and female subjects of childbearing 
potential will be included in this study only if they 
agree to use highly effective methods of 
contraception and avoid conception for defined 
periods of time before first administration of 
study drug until 30 days (females) and 90 days 
(males) after the last administration of study 
drug.
Females of childbearing potential will undergo 
serum pregnancy test at screening and then 
urine pregnancy testing at regular intervals 
during the study.
Pregnant and lactating females are not eligible 
for inclusion in the study.
Withdrawal Criteria:
If a female subject should become pregnant 
during the study, study medication should be 
discontinued. The subject will be followed to 
determine the outcome of the pregnancy. Any

pregnancy complication or elective termination of 
a pregnancy will be reported as an AE or SAE.
Drug Interaction
Non-Clinical Data:
In vitro studies with GSK2982772 assessing 
potential drug-drug interactions with Cytochrome 
P450 3A4 (CYP3A4) substrates and P-
glycoprotein (Pgp) inhibitors were completed. To 
date, formal drug interaction studies in humans 
have not been performed with GSK2982772.
There is a low risk that GSK2982772 could be an 
inducer of CYP3A4 and therefore may lower 
circulating levels of concomitant medications that 
are metabolised by CYP3A4 when co-
administered with GSK2982772.
GSK2982772 is a Pgp substrate and therefore 
co-administration with concomitant medications 
that are Pgp inhibitors could increase circulating 
levels of GSK2982772.  See Section 4.3.6 of 
GSK2982772 IB [GlaxoSmithKline Document 
Number 2014N204126_02].
Subject Selection:
Subjects who are taking concomitant 
medications known to inhibit Pgp or are CYP3A4 
narrow therapeutic index (NTI) substrates will be 
excluded from the study.
Subject Monitoring:
Subjects’ concomitant medication usage will be 
reviewed prior to inclusion and monitored 
throughout the study.
Subjects should be monitored throughout the 
study for potential effects of interaction between 
GSK2982772 and other concomitant 
medications.

3.3.2.
Benefit Assessment
The proposed study with GSK2982772 will be conducted in healthy volunteers; no 
medical benefit will be derived by volunteers’ participation. Subjects 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 GSK2982772 can be appropriately mitigated by the 
careful selection of study participants and the proposed safety monitoring procedures. As 
such, the risk to potential subjects is considered low. Routine safety and tolerability will 
be evaluated from reported 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 (Section 2) will allow for continuous medical monitoring for all 
subjects following the first dose in each treatment group. Subjects will only be discharged 
from the unit 48 hours post-dose if the Investigator deems it safe to do so.
Taking into account the measures taken to minimize risk to subjects participating in this 
study, the potential risks identified in association with GSK2982772 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 is a single-centre, randomized, double-blind (sponsor-unblinded), placebo-controlled 
study to evaluate the safety, tolerability and pharmacokinetics of GSK2982772, in repeat 
oral doses in healthy subjects. The study design schematic is depicted in Figure 1.
Figure 1
Study Design
*With Food Effect Treatment
This study is planned to include approximately 48 subjects and consists of 2 parts:

Part A (Cohort 1) – single ascending dose, randomized, placebo-controlled, 3-way 
crossover.  

Part B (Cohorts 2, 3 and 4) – repeat dose, randomized, placebo-controlled, 
sequential-group.
For TID dosing, GSK2982772 or placebo will be administered using a 7hr, 7hr and 10hr
dosing interval. For BID dosing, GSK2982772 or placebo will be administered using a 
12hr dosing interval. 
The impact of food on the PK of GSK2982772 will be investigated during the 14 Day 
repeat dose phase of the study (Part B) in Cohorts 2 and 3. On Days 1 to 14, subjects will 
fast for 8hr overnight. Breakfast will be served 2hr after dosing on Days 1 through 8, 10,

12 and 14. A standard breakfast will be served 30 minutes prior to dosing on Day 9, and a
high fat breakfast will be served 30 minutes prior to dosing on Day 11. 
All of the Cohorts in this study will be double-blind with respect to the subjects, 
investigator and site staff (with the exception of the site pharmacist). The Sponsor, the 
GSK study team, will be unblinded throughout.
5.2.
Number of Participants
Sufficient number of healthy subjects will be enrolled, such that approximately 12 
subjects in each Cohort complete dosing and critical assessments. If subjects prematurely 
discontinue the study, additional replacement subjects may be randomized in order to 
guarantee that sufficient subjects are treated with GSK2982772 at any given dose before 
escalating to the following dose. Subjects that participate in Part A of the study cannot 
participate in Part B.
5.3.
Sentinel Dosing
Sentinel dosing will be employed within each dosing period in Part A of the study. The 
doses in the single-ascending dose portion of the study (Part A) will be staggered such 
that for each of the three treatment periods, on Day 1, two of the 12 subjects will be 
randomized to treatment (one subject will receive GSK2982772 and one subject will 
receive matched-placebo). Assuming 2 subjects are dosed on Day 1 and assuming 
adequate safety in the judgment of the Principal Investigator (e.g., vital signs, ECGs, and 
AEs) through approximately 24 hours after their last dose on Day 1, the remaining 
subjects may be randomized to dosing in that period. The doses in the repeat dose portion 
of the study (Part B) will be staggered such that for each treatment period on Day 1, two 
of the 12 subjects will be randomized to treatment (one subject will receive GSK2982772 
and one subject will receive matched-placebo) and dosed for at least 7 days before the 
rest of the cohort is randomized. If participants prematurely discontinue the study, 
additional replacement participants may be recruited and assigned to the same treatment 
sequence, at the discretion of the Sponsor in consultation with the investigator.
5.4.
Dose Escalation Decisions
The decision to proceed to the next dose level of GSK2982772 within the study will be 
made by a Dose Escalation Committee (DEC) consisting of Principal Investigator, or 
delegate, and other relevant GSK clinical staff (See Section 10.5).
5.5.
Participant and Study Completion
A participant is considered to have completed the study if he/she has completed all 
phases of the study including the last scheduled procedure shown in the SoA (Section 2).
The end of the study is defined as the date of the last visit of the last participant in the 
study or last scheduled procedure shown in the SoA for the last participant in the trial 
globally.

Scientific Rationale for Study Design
In Part A, each cohort will initially evaluate the safety, tolerability and PK of 
GSK2982772 administered for 1 day as a TID or BID dosing regimen (Cohort 1). 
In Part B, the 14-day TID or BID repeat dosing (Cohort 2, 3 and 4) was chosen since it 
will provide sufficient safety and tolerability data to bridge to longer duration studies 
with the recently achieved safety margins from the 13-week toxicology study in 
monkeys. In the previous FTiH study (200975), GSK2982772 was administered up to 
120 mg BID for 14 days and was well tolerated with no safety concerns identified. Please 
see GSK2982772 IB [GlaxoSmithKline Document Number 2014N204126_02].
Cohort 4, 360 mg BID dosing regimen, may only be evaluated if the results of a modified 
release (MR) formulation study (205017) being conducted in parallel with the current 
study indicate that a MR formulation is not feasible for GSK2982772. In which case a 
BID regimen using the current immediate release formulation may be taken forward in to
Phase 2a PoC studies. Additionally, Cohort 4 dose may be modified to include the 
repetition of a previous or lower TID or BID dose based on the results of the safety and 
tolerability review or if further characterization of the safety profile at a previously tested
dose is required.     
In the previous FTiH (Study 200975), the impact of a high-fat meal on the absorption of 
GSK2982772 was investigated following single dose administration of GSK2982772 at a 
dose of 40 mg. The rate and extent of absorption was similar in the fed state as compared 
to the fasted state, although there was evidence of a time lag in the absorption in the fed 
state, probably as a result of delayed gastric emptying. It is likely that higher doses to be 
used in this study will have a similar food effect to that observed at 40 mg. Therefore,
this study plans to evaluate the impact of food during the repeat dose phase in Cohorts 2 
and 3 rather than conducting a standalone single dose food effect PK study.
5.7.
Dose Justification
An adaptive dose-escalation approach, guided by the observed safety, tolerability and 
plasma PK exposure will be taken to allow an efficient evaluation of a range of doses 
above the 120 mg BID dose that was evaluated in the FTiH study.    
The initial starting dose planned is 120 mg TID and the maximum daily dose is 
anticipated to be approximately 720 mg administered as 240 mg TID and 360 mg BID.  
For doses of up to 120 mg BID, the pharmacokinetics of GSK2982772 are approximately 
linear. Please see GSK2982772 IB [GlaxoSmithKline Document Number 
2014N204126_02]. After attainment of  Cmax, at approximately 2 hours post-dose, 
GSK2982772 concentrations decline rapidly until about 12 hours post-dose, with a t1/2 of 
approximately 2 to 3 hours. The majority of the systemic exposure to GSK2982772 is 
observed within the first 12 hours after administration. Following repeat dosing of 
GSK2982772, there is no evidence of drug accumulation for either a QD or BID dosing 
regimen. The major circulating metabolite is an N-glucuronide which accounts for 
approximately 70% of drug related material in plasma. Since glucuronidation is a high 

2017N326600_00

205184
30
capacity clearance mechanism it is unlikely that the kinetics of GSK2982772 will become 
saturable with more frequent dosing nor at the higher doses planned in the current study.   
Due to the short half-life of GSK2982772 (~2-3 hr), it is expected that steady-state will 
be achieved by Day 2 of dosing and that negligible accumulation will be observed. 
Therefore, the PK safety margins described for Day 1 and for Day 14 of dosing will be
similar. 
The predicted mean AUC(0-24) for the highest planned doses of 240 mg TID and 360 mg 
BID (40.2 μg*h/mL) approximates parity with the mean AUC(0-24) observed at the 
NOAEL (30 mg/kg/day) in the 13-week monkey toxicology study (48.4 μg*h/ml). Mean 
Cmax values for the 240 mg TID (3.21 μg/mL) and 360 mg BID (4.31 μg/mL) doses are 
predicted to be 1/4th and 1/3rd respectively, of the Cmax observed at the NOAEL (12.3 
μg/mL). The doses for Cohorts 2 and 3 may be adjusted based on PK/safety data from 
previous treatment periods. It is planned that the 95th percentile for the predicted 
AUC(0-24) values will not exceed the maximum AUC(0-24) value observed at the NOAEL
and for Cmax the 95th percentile will not exceed the mean Cmax and the NOAEL. The 
current predicted 5th -95th percentiles for AUC(0-24) and Cmax values using repeat dose PK 
data from FTiH study and mean/individual AUC(0-24) and Cmax values from the 13-week 
Monkey Study at 30 mg/kg/day (NOAEL) and 100 mg/kg/day are shown in Figure 2 and 
Figure 3, respectively.

Method of Treatment Assignment
On Day 1 participants will be assigned a unique number (randomization number) in 
ascending numerical order. The randomization number encodes the participant’s 
assignment to either GSK2982772 or placebo, according to the randomization schedule 
generated prior to the study by the Statistics Department at GSK, using validated internal 
software. 
All participants will be centrally randomized using an Interactive Voice/Web Response 
System (IVRS/IWRS). Before the study is initiated, the telephone number and call-in 
directions for the IVRS and/or the log in information & directions for the IWRS will be 
provided to the site.
Study treatment will be dispensed at the study visits summarized in SoA. Each participant 
will be dispensed blinded study treatment, labelled with his/her unique randomization 
number, throughout the study. Returned study treatment should not be re-dispensed to the 
participants
In all four cohorts, subjects will be randomized in a 3:1 ratio to either GSK2982772 or 
placebo. In Cohort 1, the subjects will be randomized to one of three sequences (ABP, 
APC, PBC), where the treatments are:
A
120 mg TID
B
240 mg TID

CONFIDENTIAL
205184

The planned dose levels are defined in Section 5.1.
The randomisation will reflect the fact that at least 2 of the 12 subjects (one subject will 
receive GSK2928772 and one subject will receive matched-placebo) will be dosed first 
(on Day 1) in each part to enable dose staggering. 
Once a treatment allocation number has been assigned to a subject, it cannot be 
reassigned to any other subject.
7.3.
Blinding
This will be a double blind (sponsor-unblinded) study and the following will apply:

The Investigator or treating physician will remain blinded to each participant’s 
assigned study treatment throughout the course of the study. In order to maintain 
this blind, an otherwise uninvolved 3rd party will be responsible for the 
reconstitution and dispensation of all study treatment and will endeavour to 
ensure that there are no differences in time taken to dispense following 
randomization

This 3rd party will instruct the participant to avoid discussing the taste, dosing 
frequency, or packaging of the study treatment with the investigator

Unblinded monitors and in the event of a Quality Assurance audit, the auditor(s) 
will be allowed access to un-blinded study treatment records at the site(s) to 
verify that randomization/dispensing has been done accurately.

The IVRS/IWRS will be programmed with blind-breaking instructions.

In case of an emergency, the investigator has the sole responsibility for 
determining if unblinding of a participant’s treatment assignment is 
warranted. Participant safety must always be the first consideration in making 
such a determination.

If the investigator decides that unblinding is warranted, the investigator should 
make every effort to contact GSK prior to unblinding a participant’s treatment 
assignment unless this could delay emergency treatment of the participant.

If a participant’s treatment assignment is unblinded, GSK must be notified 
within 24 hours after breaking the blind.

The date and reason that the blind was broken must be recorded in the source 
documentation and Case Report Form (CRF), as applicable.

A subject will be withdrawn if the subject’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 subject 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 subject’s treatment assignment, may be sent to 
investigators in accordance with local regulations and/or GSK policy.
7.4.
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 SRM.

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.
7.5.
Treatment Compliance

When the individual dose for a participant is prepared from a bulk supply, the 
preparation of the dose will be confirmed by a second member of the study site staff. 

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.
7.6.
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 
enrolment or receives during the study must be recorded along with:

The Medical Monitor should be contacted if there are any questions regarding 
concomitant or prior therapy.
Participants must abstain from taking prescription or non-prescription 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.
7.7.
Treatment after the End of the Study
Subjects will not receive any additional treatment from GSK, or with GSK2982772, after 
completion of the study because only healthy volunteers are eligible for study 
participation.

DISCONTINUATION CRITERIA
8.1.
Discontinuation of Study Treatment
8.1.1.
Dose Modification/Stopping Criteria
This protocol allows some alteration from the currently outlined dosing schedule, but the 
maximum total daily dose will not intentionally exceed the 13-week NOAEL exposure in 
monkeys. Currently, the highest planned dose is 720 mg/day of GSK2982772.
The decision to proceed to the next dose level of GSK2982772 in each part of this study 
will be made by the DEC, including the Medical Monitor and the Investigator and 
relevant clinical site staff (see Section 10.5) based on safety, tolerability, and preliminary 
PK data obtained in at least 6 subjects (through at least 24 hours post-dose) with at least 6
subjects having received active treatment (GSK2982772) at the prior 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 the PK criteria defined 
in Section 8.1.2.  Planned doses may also be repeated.
The Principal Investigator and the GSK Medical Monitor will review the following and 
dosing will be halted and progression to the next higher dose level stopped if:

One (1) or more subjects experience a SAE which has a reasonable possibility of 
relation to study drug.

Two (2) or more subjects experience a severe or clinically significant non-serious 
AE (based upon investigator judgment) which has a reasonable possibility of relation 
to study drug.

Two (2) or more subjects in a Part A cohort or 3 or more subjects in a Part B cohort 
experience the same AE of moderate severity which has a reasonable possibility of 
relation to study drug.

Consistent Common Terminology Criteria for Adverse Events (CTCAE) Nervous 
System AEs of any grade occur across subjects 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 MHRA (Medicines 
and Healthcare Products Regulatory Agency) for approval.
8.1.2.
Pharmacokinetic Dose Modification or Stopping Criteria
The 240 mg TID dose and/or the 360 mg BID dose in Cohorts 1, 3 and 4 may be adjusted 
up or down based on PK data from previous treatment periods. It is planned that the 95th

percentile for the predicted AUC(0-24) values will not exceed the maximum AUC(0-24)
value observed at the NOAEL and for Cmax the 95th percentile will not exceed the mean 
Cmax and the NOAEL. 
8.1.3.
Liver Chemistry Stopping Criteria
Liver chemistry stopping and increased monitoring criteria have been designed to 
assure participant safety and evaluate liver event etiology.
Discontinuation of study treatment for abnormal liver tests is required when:

when in the presence of abnormal liver chemistries not meeting protocol-specified 
stopping rules, the investigator believes study treatment discontinuation is in the 
best interest of the participant.

QTcF > 500 msec,

Change from baseline: QTc > 60 msec

The same QT correction formula must be used for each individual participant to 
determine eligibility for and discontinuation from the study (i.e., QTcF in this study).  

2017N326600_00
CONFIDENTIAL
205184
43
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 QTcF, then QTcF
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. If an 
ECG demonstrates a prolonged QTc, obtain 2 more ECGs over a brief period (5-10 
minutes), and then use the averaged QTc values of the 3 ECGs to determine whether 
the subject should be discontinued from the study.
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.
8.1.5.
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 becomes pregnant.

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 (See Section 8.1.3) or QTc stopping 
criteria (see Section 8.1.4) are met.

The participant experiences any signs of suicidal ideation or behaviour (See 
Section 9.3.6).
8.1.6.
Group Safety Stopping Criteria
In addition to the criteria specified above, AEs, SAEs, laboratory abnormalities, ECG 
abnormalities and changes in vital signs occurring across all randomized subjects will be 
regulatory reviewed by the Sponsor Safety Review Team (SRT) in order to ensure 
appropriate subject safety. Any changes to the study due to safety reasons will be 
promptly communicated to the appropriate Regulatory Authorities.
8.1.7.
Nervous System Stopping Criteria
The CNS observations in the 4-week GLP toxicology study in monkeys were found to be 
random, diverse, and unpredictable in monkeys (see Section 3.3.1).  There were no 
similar findings observed in the 13-week GLP toxicology study in monkeys.  The 
CTCAE Nervous System is a monitoring tool which provides the Principal Investigator 

2017N326600_00
CONFIDENTIAL
205184
44
the appropriate guidance for grading of a neurological event.  The significance of any 
neurological event experienced by a subject 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 and dosing may be halted if and 
progression to the next higher dose level stopped as per Section 8.1.1.
A subject will be withdrawn from the study if:

A Grade 3 or greater CTCAE Nervous System finding is observed or a significant 
neurologic change from a subject’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 subject withdrawal.
Note:  Appendix 7 (Section 12.7) provides Guidance for Grading Adverse Events that is 
taken from the CTCAE Version 4.03.
8.1.8.
Rechallenge
8.1.8.1.
Study Treatment Restart or Rechallenge
Study treatment restart or rechallenge after liver chemistry stopping criteria are met by 
any participant in this study is not allowed.
8.2.
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, 
behavioural, compliance or administrative reasons. The reason for withdrawal 
should be documented in the CRF.

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.
If a subject chooses to withdraw from the study after dosing, then the Investigator must 
make every effort to complete the follow-up assessments detailed in the SoA (Section 2).
8.3.
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. 

2017N326600_00
CONFIDENTIAL
205184
45
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.

STUDY ASSESSMENTS AND PROCEDURES

Study procedures and their timing are summarized in the SoA. 

Protocol waivers or exemptions are not allowed 

Immediate safety concerns should be discussed with the sponsor immediately upon 
occurrence or awareness to determine if the 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 (e.g., 
blood count) and obtained before signing of ICF may be utilized for screening or 
baseline purposes provided the procedure met the protocol-specified criteria and was 
performed within the time frame defined in the SoA.

The maximum amount of blood collected from each 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.
9.1.
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 treatment (see Section 8). 
9.1.1.
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).

2017N326600_00
CONFIDENTIAL
205184
47

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 CRF not the AE section.

All SAEs will be recorded and reported to the sponsor or designee immediately 
and under no circumstance should this exceed 24 hours, as indicated in 
Appendix 4. The investigator will submit any updated SAE data to the sponsor 
within 24 hours of it being available.

Investigators are not obligated to actively seek AEs or SAEs 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.
9.1.2.
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. 
9.1.3.
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, and non-serious AEs of special 
interest (as defined in Section 3.3.1), will be followed until the event is resolved, 
stabilized, otherwise explained, or the participant is lost to follow-up (as defined in 
Section 8.3). Further information on follow-up procedures is given in Appendix 4.
9.1.4.
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, 
IRB/ 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 

2017N326600_00
CONFIDENTIAL
205184
48
sponsor will review and then file it along with the Investigator’s Brochure and 
will notify the IRB/IEC, if appropriate according to local requirements.
9.1.5.
Pregnancy

Details of all pregnancies in female participants and, if indicated, 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 Appendix 5.

Abnormal pregnancy outcomes (e.g., spontaneous abortion, fetal death, stillbirth, 
congenital anomalies, ectopic pregnancy) are considered SAE.
9.2.
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 or treating physician should:
1.
Contact the Medical Monitor immediately.
2.
Closely monitor the participant for AE/SAE and laboratory abnormalities until 
GSK2982772 can no longer be detected systemically (at least 2 days for 
GSK2982772).
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.
9.3.
Safety Assessments
Planned time points for all safety assessments are provided in the SoA.
9.3.1.
Physical Examinations

A complete physical examination will include, at a minimum, assessments of the 
Skin, Cardiovascular, Respiratory, Gastrointestinal and Neurological systems.
Height (screening only) 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.

2017N326600_00
CONFIDENTIAL
205184
49
9.3.2.
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 
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 8.2),

may result in referral to a specialist.
9.3.3.
Vital Signs

Temperature, pulse rate, respiratory rate, and blood pressure will be assessed.

Blood pressure and pulse measurements will be assessed in a supine or semi-
supine position with a completely automated device. Manual techniques will be 
used only if an automated device is not available.

Blood pressure and pulse measurements should be preceded by at least 5 
minutes of rest for the participant in a quiet setting without distractions (e.g., 
television, cell phones).

Vital signs will be measured in a supine or semi-supine position after 5 minutes’
rest and will include temperature, systolic and diastolic blood pressure, and 
pulse and respiratory rate.

In Part A and B on Day 1, vital signs (to be taken before blood collection for 
laboratory tests) will consist of 3 pulse and 3 blood pressure measurements pre-
dose on Day 1 (3 consecutive blood pressure readings will be recorded at 
intervals of at least 1 minute). The average of the 3 blood pressure readings will 
be recorded on the CRF.
9.3.4.
Electrocardiograms

Triplicate 12-lead ECG will be obtained as outlined in the SoA (see Section 2) 
using an ECG machine that automatically calculates the heart rate and measures 
PR, QRS, QT, and QTc intervals. Refer to Section 8.1.4 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 with at least 2 
minutes but no more than 10 minutes apart. 

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.

9.3.5.
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 
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 SRM and the SoA.
9.3.6.
Suicidal Risk Monitoring
GSK2982772 is considered to be a CNS-active drug.  There is some concern that some 
CNS-active drugs may be associated with an increased risk of suicidal thinking or 
behaviour when given to some subjects. Although this drug has not been shown to be 
associated with an increased risk of suicidal thinking or behaviour when given to healthy 
volunteers, GSK considers it important to monitor for such events before or during 
clinical studies with compounds such as this.
Participants being treated with GSK2982772 should be monitored appropriately and 
observed closely for suicidal ideation and behaviour or any other unusual changes in 
behaviour. All subjects who experience signs of suicidal ideation or behaviour must 
immediately be discontinued from study medication.
Families and caregivers of participants being treated with GSK2982772 should be alerted 
about the need to monitor participants for the emergence of unusual changes in 
behaviour, as well as the emergence of suicidal ideation and behaviour and to report such 
symptoms immediately to the study investigator.
At screening and baseline (pre-dose Day 1) in Part B only, the Baseline/Screening 
assessment of suicidal ideation and behaviour and treatment emergent suicidal ideation 
and behaviour will be monitored during study 205184 using C-SSRS. At Days 7 and 17 
of the study, the ‘Since Last Visit C-SSRS’ will be completed. Refer to Section 2, SoA,
for more information.
Subjects who answer ‘Yes’ to any suicidal behaviour or ‘Yes’ to suicidal ideation 
Questions 4 or 5 will be referred to their General Practitioner (GP) or appropriate 

2017N326600_00

51
psychiatric care. The medical monitor will be notified. If appropriate, an AE or SAE 
should be reported (see Section 9.1). In addition, the investigator should complete a 
Possible Suicidality Related Adverse Event (PSRAE) form to collect detailed information 
on the circumstances of the reported AEs which, in the investigator’s opinion, are 
possibly suicidality-related. These may include, but are not limited to, an event involving 
suicidal ideation, a preparatory act toward imminent suicidal behaviour, a suicide 
attempt, or a completed suicide.
9.4.
Pharmacokinetics
9.4.1.
Blood Sample Collection 
Blood will be collected into EDTA tubes and processed to plasma for PK analysis of 
GSK2982772 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.  
Blood will be collected into EDTA tubes and processed to plasma for PK analysis of M8 
(GSK3562183) and M9 (GSK2997852). This will be collected at the time points 
indicated in Section 2, SoA Tables. The actual date and time of each blood sample 
collection will be recorded. 
Blood will be collected into EDTA tubes and processed to plasma for
4β-hydroxycholesterol and cholesterol. This will be collected at the time points indicated 
in Section 2, SoA Tables. The actual date and time of each blood sample collection will 
be recorded. 
Details of blood sample collection, processing, storage and shipping procedures are 
provided in the SRM. 
9.4.2.
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 GSK2982772
will be determined in plasma samples, and concentrations of M8 (GSK3562183) and M9 
(GSK2997852) will be determined in select plasma samples, 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 GSK2982772 (or M8 [GSK3562183] and 
M9 [GSK2997852] as indicated above), any remaining plasma sample may be analysed
for other compound-related material and the results may be reported under a separate 
PTS-IVIVT, 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.

Plasma Sample for CYP3A4 Enzyme Activity
Plasma derived from select PK blood samples in Part B (as in the SoA Table), will be 
analyzed for 4β-hydroxycholesterol and cholesterol as a potential in vivo marker of 
CYP3A4 enzyme activity. Samples collected pre-treatment and at steady-state will be 
compared to evaluate this potential marker.
Details on CYP3A4 enzyme activity marker plasma sample collection, processing, 
storage and shipping procedures are provided in the SRM.
Baseline and Day 14, post-treatment plasma samples will be analyzed using a validated, 
specific, and sensitive liquid chromatography–mass spectrometry (LC-MS/MS) method 
to determine concentrations of 4β-hydroxycholesterol and total cholesterol.  A 
comparison will be made between the ratio of 4β-hydroxycholesterol : cholesterol at 
baseline and on Day 14 to assess potential changes in CYP3A4 enzyme activity 
following GSK2982772 treatment.
Analysis will be performed at a bioanalytical site (to be detailed in the SRM) under the 
control of PTS-IVIVT and Third Party Resource, GlaxoSmithKline.

STATISTICAL CONSIDERATIONS
The objectives of this study are to assess the safety and tolerability of single and repeat 
ascending doses of GSK2982772. No formal hypotheses will be tested.  
An estimation approach will be used to describe PK of GSK2982772, where point 
estimates and corresponding 90% confidence intervals will be constructed.
10.1.
Sample Size Determination
No statistical techniques were used to calculate the sample size, and sample size is based 
on feasibility.
The primary objective of the study is safety, where the number of safety events are of 
interest.  A maximum of 9 subjects will receive each active dose and; therefore, if 0/9 of 
a particular safety event in the GSK2982772 group is observed, the upper limit of the 
exact 95% CI indicates that a true incidence rate of 33.6% could not be ruled out.  
Whereas if 1/9 of the same safety event in the GSK2982772 group is observed, the upper 
limit of the exact 95% CI indicates that a true incidence rate of 48.2% could not be ruled 
out.

2017N326600_00
CONFIDENTIAL
205184
53
Using a Bayesian approach to determine the confidence interval around an observed 
safety event, we would assume a flat Beta (1,1) prior, and if we were to observe one
safety event in 9 then the posterior distribution would be Beta (2, 9), as outlined below:
Bayesian Approach to Determine Confidence in a Safety Event.
Thus, we can be 95% certain that the true probability of the safety event lies between 
0.04 and 0.39.
Pharmacokinetic Parameters
To date the pharmacokinetics of GSK2982772 have been studied up to 120 mg BID. The 
maximum between-subject coefficient of variation (CVb) for AUC(0-τ) and Cmax observed 
in study 200975 was 27.1 and 36.1 respectively. 
Based on these estimates of variability, slightly more conservative for a cross-over study
and a sample size of 9 completers in Cohort 2, it is estimated that the lower and upper 
bounds of the 90% confidence interval for the means of AUC and Cmax will be within 
approximately 17.9% and 24.2% of the point estimate, respectively.
10.2.
Sample Size Sensitivity
A sample size sensitivity analysis has been conducted on the primary endpoint, to 
investigate different safety event rates. If the number of subjects who completed each 
active dose, then the true incidence rates of safety events that could not be ruled out (as 
outlined in Section 10.1 Sample Size Determination) would change.  These changes are 
outlined in Table 1:

An interim analysis may be performed during the study on completed cohorts in Part A 
and Part B of the study to aid internal decision making only. There will be no changes to 
the study design or planned number of subjects in future cohorts as a result of the interim 
analysis.
For Parts A and B of the study, interim PK analyses will be performed on plasma 
GSK2982772 concentration-time data generated during the conduct of this study.
The decision to proceed to higher dose strengths will be made by the DEC based on 
assessment of safety, tolerability and pharmacokinetic data at the preceding dose. The 
exception to this will be in Part A where only a safety assessment (not PK) for the 120 
mg TID dose will be performed. To date, the PK of GSK2982772 has been well-
characterised up to 120 mg BID in the FTiH study and the 120 mg TID for Part A 
represents a 50% increase in dose where PK simulations are predictable. This analysis 
can include review of individual subject data, summaries, graphical presentations and/or 
statistical analysis.
The RAP will describe the planned interim analyses in greater detail.
10.5.
Dose Escalation Committee
The decision to proceed to the next dose level of GSK2982772 in each Cohort will be 
made by a DEC consisting of the Principal Investigator (or appropriate designee), 
Medical Monitor, GSK Clinical Investigational lead and/or Study Team Leader, GSK 
Pharmacokineticist, a GSK GCSP representative and GSK Statistician. All GSK 
personnel including the GSK Statistician and the GSK Pharmacokineticist will remain 
unblinded throughout the course of the study. 
For Part A, dose escalation decisions will be based on data obtained from 6 or more 
subjects receiving GSK2982772 at the prior dose level. The review of the data set will

consist at a minimum of: listings of all AEs, clinical laboratory results, flagged vital 
signs, flagged findings during continuous cardiac monitoring (telemetry), ECG and PK 
results derived from 24-hour plasma profiles.
The decision and selection of dose to proceed to Part B, will be made by the DEC based 
on safety, tolerability, and PK data from the same dose levels evaluated in Part A.  
For Part B, dose escalation decisions will be based on data obtained from 6 or more 
subjects receiving GSK2982772 at the prior dose level. The review of the data set will 
consist at a minimum of: listings of all AEs, clinical laboratory results, flagged vital 
signs, flagged findings during continuous cardiac monitoring (telemetry) and ECG 
findings through Day 16 of the previous cohorts(s) in Part B. Also included will be any 
PK results derived through at least Day 7 of the previous cohort(s).

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 assessmentse.g.eg, 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 
leads to the procedure is the AE.

Situations in which an untoward medical occurrence did not occur (social and/or 

2017N326600_00
CONFIDENTIAL
205184
69
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 fulfils any other serious criteria, the event is 
serious. When in doubt as to whether “hospitalization” occurred or was necessary, the AE 
should be considered serious.
Hospitalization for elective treatment of a pre-existing condition that did not worsen from 
baseline is not considered an AE.
d.
Results in persistent disability/incapacity

The term disability means a substantial disruption of a person’s ability to conduct 
normal life functions.

This definition is not intended to include experiences of relatively minor medical 
significance such as uncomplicated headache, nausea, vomiting, diarrhoea, influenza, 
and accidental trauma (e.g., sprained ankle) which may interfere with or prevent 
everyday life functions but do not constitute a substantial disruption.
e.
Is a congenital anomaly/birth defect
f.
Other situations:

Medical or scientific judgment should be exercised in deciding whether SAE 
reporting is appropriate in other situations such as important medical events that may 
not be immediately life-threatening or result in death or hospitalization but may 
jeopardize the participant or may require medical or surgical intervention to prevent 

2017N326600_00
CONFIDENTIAL
205184
70
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.
Assessment of Causality

The investigator is obligated to assess the relationship between study treatment and 

2017N326600_00
CONFIDENTIAL
205184
71
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

Appendix 5: Contraceptive Guidance and Collection of 
Pregnancy Information
Definitions
Woman of Childbearing Potential (WOCBP)
A woman is considered fertile following menarche and until becoming post-menopausal 
unless permanently sterile (see below)
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

Documented tubal ligation
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 enrolment.
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 

2017N326600_00
CONFIDENTIAL
205184
74

Agree to use a male condom plus an additional method of contraception 
with a failure rate of <1% per year as described in Table 4 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

In addition, male participants must refrain from donating sperm for duration of 
study and for 90 days after study completion or from last dose
Female participants
Female participants of childbearing potential are eligible to participate if they agree to 
use a highly effective method of contraception consistently and correctly as described in 
Table 4. 
Table 4
Highly Effective Contraceptive Methods

Highly Effective Methods That Are User Independent 

Implantable progestogen-only hormonal contraception associated with inhibition of 
ovulationb

Intrauterine device (IUD)

Intrauterine hormone-releasing system (IUS)

bilateral tubal occlusion
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 

2017N326600_00
CONFIDENTIAL
205184
75
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 7 days after the last dose of study treatment 
Pregnancy Testing

WOCBP should only be included after a confirmed menstrual period and a negative 
highly sensitive serum pregnancy test 

Additional pregnancy testing at admission to each study period and at the follow-up 
visit.

Pregnancy testing will be performed whenever a menstrual cycle is missed or when 
pregnancy is otherwise suspected.

Pregnancy testing, with a sensitivity of 25 mIU/mL will be performed using the test 
kit approved by the sponsor and in accordance with instructions provided in its 
package insert.
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.

Female Participants who become pregnant

Investigator will collect pregnancy information on any female participant, who 
becomes pregnant while participating in this study. 

Information will be recorded on the appropriate form and submitted to GSK within 
24 hours of learning of a participant's pregnancy. 

Participant will be followed to determine the outcome of the pregnancy. The 
investigator will collect follow up information on participant and neonate, which will 
be forwarded to GSK Generally, follow-up will not be required for longer than 6 to 8 
weeks beyond the estimated delivery date.  

Any termination of pregnancy will be reported, regardless of fetal status (presence or 
absence of anomalies) or indication for procedure. 

While pregnancy itself is not considered to be an AE or SAE, any pregnancy 
complication or elective termination of a pregnancy will be reported as an AE or 
SAE. 

A spontaneous abortion is always considered to be an SAE and will be reported as 
such.  

Any SAE occurring as a result of a post-study pregnancy which is considered 
reasonably related to the study treatment by the investigator, will be reported to GSK
as described in Appendix 4. While the investigator is not obligated to actively seek 
this information in former study participants, he or she may learn of an SAE through 
spontaneous reporting. 
Any female participant who becomes pregnant while participating will discontinue study 
treatment.

Amendment 01 07-Dec-2017
Overall Rationale for the Amendment:
Clarification of the allowed contraception methods for female participants of child 
bearing potential and male participants with female partners of child bearing potential. 
Pharmacogenetic sampling has been incorporated into the protocol and glucuronide levels 
will be assessed in Part A of the study, as well as Part B. In addition, further 
administrative clarifications have been made.

Information
An additional line for ‘Highly 
effective contraceptive method 
(WOCBP only)’ and ‘Contraception 
with male condoms (WOCBP using 
hormonal contraceptive method 
and male subjects with female 
partners of childbearing potential 
only)’ has been added to the SoA 
tables in Section 2.1. and Section 
2.2.
Updated wording for the subject 
selection for the risk of 
Reproductive Toxicity.
Updated wording for Inclusion 
Criteria 4 for Male and Female 
subjects.
Update of the contraception 
guidance wording for women of 
child bearing potential and male 
subjects with female partners of 
child bearing potential.
Female subjects of child-bearing potential 
who use hormonal contraception are 
required to have their sexual partners use a 
male condom from the first dose of study 
drug until the follow-up visit to avoid 
conception until at least 30 days after the 
last administration of drug.
This is being added as a precautionary 
measure for all WOCBP because an AE of 
“breakthrough bleeding” was reported in 
Cohort 1 TP2 of this study in a female 
subject who is on a combination oral 
contraceptive pill. In the FTiH Study 
200975, there was no increase detected in 
an in vivo marker for CYP3A4 enzyme 
activity following repeat dose administration 
up to 120 mg BID.  Measurement of 4β-
hydroxycholesterol is being evaluated in 
this study to determine CYP3A4 enzyme 
activity in repeat dose administration up to 
720 mg/day.  Until data are available the 
added contraception is being required.

to the protocol (9.6) and appendix 
(6)
To take a pharmacogenetic sample from 
consenting subjects.
One subject in Cohort 1 (not the subject 
with break through bleeding), had 
consistently high exposure to GSK2982772 
compared to the other subjects (~2-fold 
higher Cmax) for the 120 mg and 240 mg 
TID dose levels. This may be due to a 
UGT1A9 genetic polymorphism, which is 
responsible for the conversion to the 
glucuronide metabolite of GSK2982772.

Clinical 
Laboratory 
Tests
In Part A of the study, 
Haem/Chem/Urinalysis 
assessments can be non-fasted for 
Day -1 and the Follow-Up Visit.
In Part B of the study 
Haem/Chem/Urinalysis 
assessments can be non-fasted for 
Day -1 only.
Additional wording included to Note 
2 in Table 3 - Non-fasted samples 
can be collected on Day -1 (All 
Parts) and at the Follow-Up visit 
(Part A Only).
The fasting lipid panel in Part B was 
separated out in the SoA since it was noted 
to be performed on Day -1 or Day 1.  This 
was moved to Day 1 only since subjects will 
not be fasted on Day -1. The 4β-
hydroxycholesterol will be checked on Day 
1, as a fasted sample.
It is recommended that all other lab time 
points being performed (inclusive of the 
follow-up visit) are to be performed under 
fasted conditions since this is essential to 
assess lipid profiles.
6.2. Exclusion 
Criteria
An additional Exclusion Criteria 
(16) has been added. “The subject 
has participated in a clinical trial 
and has received an investigational 
product within the following time 
period prior to the first dosing day 
in the current study: 30 days, 5 
half-lives or twice the duration of 
the biological effect of the 
investigational product (whichever 
is longer). All subsequent exclusion 
criteria numbers have increased by 
1.
To define the minimum length of time since 
a subject was last exposed to a new 
chemical entity.

section under the procedure 
“Randomization” in Section 2.1. 
and Section 2.2 to state:
“Randomization can occur on either 
Day -1 or Day 1 in both Parts A and 
B of the study.”
Updated wording to include that 
randomization can take place on 
Day -1 or Day 1 in Section 7.2.
There was a discrepancy in the SoA under 
the procedure “Randomization” in both Part 
A and B on Day -1 and Section 7.2. 
Randomization can take place on either 
Day -1 or Day 1.

Description of Change
Brief Rationale
Assignment
9.3.3. Vital 
Signs
The semi-supine position has been 
removed from this section.
To remove any ambiguity with this 
assessment, the supine position will be the 
only position used to assess vital signs.
2.2. Time and 
Events Table 
– Part B 
(Cohorts 2-4)
A comment has been added to the 
Meals row to state that “Meals will 
be served as per the site schedule
on Days -1, 16 and 17.”
Clarification of the wording for the meal 
schedule on non-dosing and non PK 
sampling days.
2.2. Time and 
Events Table 
– Part B 
(Cohorts 2-4)
Superscript ‘g’ has been removed 
from the PK blood sampling on Day 
1.
Superscript ‘g’ refers to study assessments 
on Day 14 of the protocol and not Day 1. 
This is a correction of a typographical error.
6.2. Exclusion 
Criteria
Update of the wording in Exclusion 
Criteria 3 to change the definition of 
what constitutes a positive 
tuberculin skin test from <5 mm 
skin induration at 48 to 72 hours to 
>5 mm skin induration at 48 to 72 
hours.
Correction of a typographical error. An 
induration of >5 mm skin induration at 48 to 
72 hours is considered a positive TB test.
7.2. Method 
of Treatment 
Assignment
The Method of Treatment 
Assignment has been updated to 
note that subjects in Cohort 1 will 
be randomized to 1 of 4 treatment 
sequences rather than 1 of 3. The 
additional treatment sequence 
(ABC) has been added. 
Correction of a typographical error. There is 
no change to the randomization ratio, which 
is 3:1.
2.1. Time and 
Events Table 
– Part A 
(Cohort 1)
Removal of the 10hr time interval 
post-last dose in note ‘b’ for TID 
dosing. This now reads “TID 
dosing: GSK2982772 or placebo 
will be administered using a 7hr, 
7hr dosing interval.”
Correction of a typographical error. Since 
Part A is a single-day of dosing, this 10hr 
interval has been removed.
2.2. Time and 
Events Table 
– Part B 
(Cohorts 2-4)
The Neurological Examination 
originally on Day 4 has been 
moved to Day 3.
Correction of a typographical error. 48hr 
post-first dose assessment would be on 
Day 3.
6.2. Exclusion 
Criteria
Exclusion Criteria 29 has been 
updated to state “Fasting total 
cholesterol” rather than “Total 
fasting cholesterol”.
Correction of typographical error.

PROTOCOL SYNOPSIS FOR STUDY 205184
Protocol Title: A single-centre, randomized, double-blind (sponsor-unblinded), placebo-
controlled study to evaluate the safety, tolerability and pharmacokinetics of GSK2982772 
in repeat oral doses in healthy subjects.
Short Title: GSK2982772 high dose safety and PK study in healthy volunteers.
Rationale: The purpose of this study is to evaluate the safety, tolerability and 
pharmacokinetics (PK) of repeat oral doses of GSK2982772 (TID and BID, if required) 
in healthy subjects. TID dosing will be administered as a 7hr, 7hr, 10hr dosing interval 
and BID as a 12hr dosing interval. 
Objectives and Endpoints:
Objective
Endpoint

Part B, the PK profile will be evaluated 
following the first dose only. Derived PK 
parameters for GSK2982772, including area 
under the plasma drug concentration versus 
time curve over 24 hr (AUC(0-24)) and AUC 
over each dose interval (i.e. AUC(0-7), AUC(7-
14) and AUC(14-24) for TID and AUC(0-12) and 
AUC(12-24) for BID). Maximum observed 
plasma drug concentration (Cmax) following
each dose, time to maximum observed 
plasma drug concentration (Tmax) following 
each dose, observed trough plasma drug 
concentrations (C0, C7, C14 and C24 for TID
dosing and C0, C12 and C24 for BID dosing).

To assess the impact of food on the PK of 
repeat doses of GSK2982772 in healthy 
subjects at steady state

Derived PK parameters for GSK2982772, 
including AUC(0-7), AUC(7-14), Cmax, after 1st

single-day and repeat dosing of 
GSK2982772.

Quantify M8 (GSK3562183) and M9 
(GSK2997852) in select plasma PK 
samples after single-day dosing and at pre-
dose and 2 hr following Day 14 of repeat 
dosing of GSK2982772.
Overall Design:
This is a single-centre, randomized, double-blind (sponsor-unblinded), placebo-controlled 
study to evaluate the safety, tolerability and pharmacokinetics of GSK2982772, in repeat 
oral doses in healthy subjects. The study design schematic is depicted in the Figure

Type and Number of Participants:
Healthy volunteer subjects will be enrolled, such that up to approximately 12 subjects (9 
active, 3 placebo) in each Cohort (up to approximately 48 in total) complete dosing and 
critical assessments. A subject is defined to have completed the study when he/she has 
attended all study visits.
Sentinel dosing will be employed within each Cohort for both Part A and Part B of the 
study. The doses in the single-ascending dose portion of the study (Part A) will be 
staggered such that for each of the three treatment periods, on Day 1, two of the 12 
subjects will be randomized to treatment (one subject will receive GSK2982772 and one 
subject will receive matched-placebo). Assuming 2 subjects are dosed on Day 1 and 
assuming adequate safety in the judgment of the Principal Investigator (e.g., vital signs, 
ECGs, and adverse events) through approximately 24 hours after their last dose on Day 1, 
the remaining subjects may be randomized to dosing in that period. The doses in the 
repeat dose portion of the study (Part B) will be staggered such that for each treatment 
period on Day 1, two of the 12 subjects will be randomized to treatment (one subject will 
receive GSK2982772 and one subject will receive matched-placebo) and dosed for at 
least 7 days before the rest of the cohort is randomized. Assuming 2 subjects are dosed on 
Day 1 to 7 and assuming adequate safety in the judgment of the Principal Investigator 
(e.g., vital signs, ECGs, and adverse events) through approximately Day 7, the remaining 
subjects may be randomized to dosing.
If subjects prematurely discontinue the study, additional replacement subjects may be 
randomized in order to guarantee that sufficient subjects are treated with GSK2982772 at 
any given dose before escalating to the following dose. Replacement subjects will be 
assigned to the same treatment sequence (Cohort 1) or treatment (Cohorts 2-4) and start 
from the period to be replaced at the discretion of the Sponsor and in consultation with 
the Principal Investigator.
Treatment Groups and Duration:
The study duration, including screening and follow-up, is not expected to exceed 
13 weeks for Part A and 8 weeks for Part B of the study.
Study Duration – Cohort 1
Screening
Approximately 28 days.
Number of Subjects
One Cohort of 12 subjects (N=12).
Treatment Period
Cohort 1 will comprise of three treatment periods, investigating three dosing regimens. 
Each dose regimen consists of 1 day treatment duration, with subjects in house for 4
nights (through at least 48 hours post-last dose). Subjects will be admitted to the unit 
the day before dosing, will remain in the unit overnight, and will be released following 
completion of the assessments on Day 4 of each treatment period, provided there are 
no safety concerns.
Washout Period 
Will be at least 7 days between dose regimens for an individual subject.
Follow-up
At least 7 days and no greater than 14 days after last study drug administration. If 
warranted, additional follow-up visits may be scheduled.

SCHEDULE OF ACTIVITIES (SOA)
Protocol waivers or exemptions are not allowed with the exception of immediate safety 
concerns. Therefore, adherence to the study design requirements, including those 
specified in the Schedule of Activities (SoA) tables (Section 2.1 and Section 2.2), are 
essential and required for study conduct.
Supplementary study conduct information not mandated to be present in this protocol is 
provided in the Study Reference Manual (SRM). The SRM will provide the site 
personnel with administrative and detailed technical information that does not impact 
subject safety.
This section lists the procedures and parameters of each planned study assessment. The 
exact timing of each assessment is listed in the SoA tables (Section 2.1 and Section 2.2).
The following points must be noted:

If assessments are scheduled for the same nominal time, THEN the assessments 
should occur in the following order:
1. 12-Lead ECG
2. Vital Signs
3. Blood Draws
Note: The timing of the assessments should allow the blood draw to occur at the exact 
nominal time.

The timing and number of planned study assessments, including safety, 
pharmacokinetic, or other 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.

The change in timing or addition of time points for any planned study assessments 
must be documented in a Note to File, which is approved by the relevant GSK 
study team member and then archived in the study sponsor and site study files, 
but this will not constitute a protocol amendment.

No more than 500 mL of blood will be collected over the duration of the study, 
including any extra assessments that may be required.

The Institutional Review Board/Independent Ethics Committee (IRB/IEC) will be 
informed of any safety issues that require alteration of the safety monitoring 
scheme or amendment of the Informed Consent Form.
A table defining the allowed variance in timings of assessments without being considered 
a protocol deviation will be included in the SRM.


The timing and number of planned study assessments, including safety, pharmacokinetic or other 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 must be documented and approved by 
the relevant study team member and then archived in the sponsor and site study files, but will not constitute a protocol 
amendment. The IRB/IEC will be informed of any safety issues that require alteration of the safety monitoring scheme or 
amendment of the informed consent form (ICF).

INTRODUCTION
3.1.
Study Rationale
The current study is being conducted to support administration of higher dose levels than 
initially studied in the First Time in Human (FTiH) study - 200975. The dose in the FTiH 
study was capped at 120 mg BID based on exposure margins with the no observable
adverse effect limit (NOAEL) in the 28-day monkey toxicology study (10 mg/kg/day). 
Subsequently, a 13-week toxicity study in monkeys has completed which increased the 
NOAEL to 30 mg/kg/day which will allow for an approximate 4-fold increase in the 
safety margins, in terms of systemic exposure to GSK2982772. The current study is 
being conducted to explore administration of higher dose levels than achieved in the 
FTiH study to support subsequent Phase 2a Proof of Concept (PoC) studies and Phase 2b 
dose range studies in subjects with psoriasis (PsO), rheumatoid arthritis (RA) and 
ulcerative colitis (UC).
3.2.
Background
GSK2982772 is a first-in-class, highly selective, small molecule inhibitor of receptor-
interacting serine/threonine protein-1 (RIP1) kinase. RIP1 is a member of the receptor-
interacting serine/threonine kinase family containing an amino-terminal kinase domain, 
an intermediate domain and a carboxy-terminal death domain. RIP1 regulates 
inflammatory signalling in response to stimuli such as tumour necrosis factor (TNF) and 
ligands of the Toll-like receptor family in both kinase-dependent and -independent 
manners [Ofengeim, 2013]. Upon binding to its receptor, tumour necrosis factor receptor-
1 (TNFR1), TNFα triggers one of three distinct cellular fates; NFκB activation, apoptosis, 
or the more recently identified programmed necrosis [Ofengeim, 2013]. In addition, 
recent studies have shown that the programmed necrosis signalling complex also 
regulates the induction of certain cytokines. Although RIP1 serves as a key decision 
checkpoint for all three of these pathways, its kinase activity is only requisite for the 
initiation of programmed necrosis and pro-inflammatory cytokine production [Berger, 
2014]. The discovery of this newly defined inflammatory, programmed necrotic pathway 
calls into question the major contributor to human disease downstream of the TNFR1. As 
such, a RIP1 kinase inhibitor represents a novel, selective mechanism for the treatment of 
inflammatory conditions such as Crohn’s Disease, Plaque Psoriasis, and Rheumatoid 
Arthritis through multiple mechanisms, including the blockade of cell death, danger 
associated molecular pattern (DAMP)-driven inflammation and pro-inflammatory 
cytokine production.

Investigational Product (IP) GSK2982772
Central Nervous System (CNS) Effects
Non-Clinical Data:
In the 4-week GLP toxicology study, CNS 
findings were observed in 2/12 monkeys which 
were administered 100 or 300 mg/kg/day. CNS 
findings included uncoordination, irregular gait, 
trembling, hunched appearance and decreased 
activity. The NOAEL for this study was 
determined at 10 mg/kg/day.
In the 13-week GLP toxicology study, there were 
no CNS findings observed in monkeys 
administered 10, 30 or 100 mg/kg/day. The 
NOAEL for this study was determined at 30 
mg/kg/day.
Clinical Data:
A FTiH study with single ascending and multiple 
ascending dose study has been performed in 67 
healthy male volunteers to date (see IB 
[GlaxoSmithKline Document Number 
2014N204126_02]). No drug-associated CNS 
adverse events (AEs) were identified and no 
Serious AEs (SAEs) were reported.
Subject Selection:
Subjects with known history of significant 
neurologic disorders including but not limited to 
progressive multiple sclerosis (MS), Amyotrophic
lateral sclerosis (ALS), Alzheimer’s and dementia 
will be excluded. 
Individuals with potentially increased 
susceptibility for neurologic effects will be 
excluded based on medical history at screening.
Subject Monitoring:
Subjects will be monitored for standard CNS-
related AEs.

Potential Risk of Clinical Significance
Summary of Data/Rationale for Risk 
Mitigation Strategy
Immunosuppression
The possibility of immunosuppression, including 
an increase in the frequency and/or severity of 
infection, may result from the intended 
pharmacologic effect of GSK2982772. This may 
be enhanced in subjects taking other 
immunomodulating drugs or corticosteroids.
Clinical Data:
In the FTiH study, no SAEs were reported. One 
subject experienced an Adverse Event (AE) 
herpes zoster approximately 27 days after 
receiving his last dose with GSK2982772 or 
placebo. The blinded investigator determined this 
to be potentially drug-related.
Subject Selection:
Subjects with recurrent, chronic or active 
infections will be excluded from the study.
Subjects will be screened for TB, HIV, Hepatitis 
B and C, and excluded from the study if positive.
Investigators are expected to follow local and/or 
national guidelines with respect to vaccinations, 
including against influenza and pneumococcus.
Subject Monitoring:
Subjects will be monitored for signs of infection.
See Individual Safety Stopping Criteria for 
atypical or opportunistic infections (Section 
8.1.5).
Vaccinations
There is a theoretical risk that GSK2982772 
could decrease an individual’s immune response 
to vaccines or allow symptoms to develop 
following vaccination with a live vaccine when 
administered while on therapy.
Subject Selection:
Attenuated or live vaccines should not be 
administered to subjects from 30 days prior to 
the first dose of GSK2982772, during the study 
and for 5 half-lives plus 30 days (total 32 days) 
after GSK2982772 is discontinued.

Potential Risk of Clinical Significance
Summary of Data/Rationale for Risk 
Mitigation Strategy
If indicated, non-live vaccines (e.g. inactivated 
influenza vaccines) may be administered while 
receiving GSK2982772 based on a treating 
physician assessment of the benefit: risk (e.g., 
risk of theoretical decreased responsiveness).
Investigators will be expected to have followed 
local and/or national guidelines with respect to 
vaccinations, including against influenza and 
pneumococcus.
Respiratory
Non-clinical data:
In the single-dose Safety Cardiovascular and 
Respiratory Study in monkeys, a decrease in 
minute volume (MV) and respiratory rate was 
observed at all doses (10, 100, and 300 mg/kg).  
These findings were noted to be reversible and 
mild in severity.
In a 14-day repeat dose Safety Respiratory 
Study in monkeys, no respiratory effects on total 
pulmonary ventilation (MV) or respiratory rate 
were observed at doses of 1 or 10 mg/kg/day. 
See IB for GSK2982772 [GlaxoSmithKline 
Document Number 2014N204126_02].
Subject Monitoring:
Subjects should be monitored for standard 
respiratory-related AEs.
Vital signs will be monitored during study visits.

Potential Risk of Clinical Significance
Summary of Data/Rationale for Risk 
Mitigation Strategy
Clinical data:
In the FTiH study, repeat doses of GSK2982772 
up to 120 mg BID were administered x 14 days 
in 48 healthy male volunteers. Extensive 
respiratory monitoring with end-tidal CO2 
(ETCO2), oxygen saturation (SpO2) and 
nocturnal respiratory rate monitoring was 
performed.   No SAEs occurred, and no drug-
associated respiratory-related AEs were 
identified.
Suicidality
GSK2982772 is considered to be a CNS-active 
drug based on pre-clinical studies.
Clinical Data:
In the FTiH study, there have been some reports 
of lethargy, abnormal dreams and depressed 
mood. No events of suicidal ideation or 
behaviour or changes in behaviour were 
reported.
Subject Selection:
Subjects with a current history of Suicidal 
Ideation Behaviour (SIB) as measured using the 
Columbia Suicide Severity Rating Scale (C-
SSRS) or a history of attempted suicide will be 
excluded from the study.
Subject Monitoring:
Subjects should be monitored appropriately and 
observed closely for suicidal ideation and 
behaviour or any other unusual changes in 
behaviour.

personnel using the C-SSRS in all subjects.
Reproductive Toxicity
Non-Clinical Data:
In the rat embryofetal development study, there 
were no maternal or developmental toxicity at 
doses ≤200 mg/kg/day.
In the rabbit embryofetal development study, 
GSK2982772 was administered at doses of 0, 
10, 100, 300 or 600 mg/kg/day on gestation day 
7 to 19. No developmental toxicity was evident at 
doses up to 300 mg/kg/day.
Subject Selection:
Female subjects of childbearing potential will be 
included in this study only if they agree to use 
one of the highly effective methods of 
contraception beginning at least 28 days prior to 
first dose of study drug until 30 days after the last 
administration of study drug. Women using a 
hormonal contraceptive method will also be 
required to have partners use a male condom 
from the first dose of study drug and until the 
follow-up visit to avoid conception until at least 
30 days after the last administration of study 
drug.  
Male subjects with female partners of 
childbearing potential must agree to use male 
condoms to avoid conception for defined periods 
of time before first administration of study drug 
until 90 days after the last administration of study 
drug. It is also recommended that a male subject 
with a female partner of childbearing potential 
employ a highly effective contraceptive method 
throughout this same period of time.
Females of childbearing potential will undergo

urine pregnancy testing at regular intervals 
during the study.
Pregnant and lactating females are not eligible 
for inclusion in the study.
Withdrawal Criteria:
If a female subject should become pregnant 
during the study, study medication should be 
discontinued. The subject will be followed to 
determine the outcome of the pregnancy. Any 
pregnancy complication or elective termination of 
a pregnancy will be reported as an AE or SAE.
Drug Interaction
Non-Clinical Data:
In vitro studies with GSK2982772 assessing 
potential drug-drug interactions with Cytochrome 
P450 3A4 (CYP3A4) substrates and P-
glycoprotein (Pgp) inhibitors were completed. To 
date, formal drug interaction studies in humans 
have not been performed with GSK2982772.
There is a low risk that GSK2982772 could be an

circulating levels of concomitant medications that 
are metabolised by CYP3A4 when co-

GSK2982772 is a Pgp substrate and therefore 
co-administration with concomitant medications 
that are Pgp inhibitors could increase circulating 
levels of GSK2982772.  See Section 4.3.6 of

Benefit Assessment
The proposed study with GSK2982772 will be conducted in healthy volunteers; no 
medical benefit will be derived by volunteers’ participation. Subjects 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 GSK2982772 can be appropriately mitigated by the 
careful selection of study participants and the proposed safety monitoring procedures. As 
such, the risk to potential subjects is considered low. Routine safety and tolerability will 
be evaluated from reported 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 (Section 2) will allow for continuous medical monitoring for all 
subjects following the first dose in each treatment group. Subjects will only be discharged 
from the unit 48 hours post-dose if the Investigator deems it safe to do so.
Taking into account the measures taken to minimize risk to subjects participating in this 
study, the potential risks identified in association with GSK2982772 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 is a single-centre, randomized, double-blind (sponsor-unblinded), placebo-controlled 
study to evaluate the safety, tolerability and pharmacokinetics of GSK2982772, in repeat 
oral doses in healthy subjects. The study design schematic is depicted in Figure 1.
Figure 1
Study Design
*With Food Effect Treatment
This study is planned to include approximately 48 subjects and consists of 2 parts:

Part A (Cohort 1) – single ascending dose, randomized, placebo-controlled, 3-way 
crossover.  

Part B (Cohorts 2, 3 and 4) – repeat dose, randomized, placebo-controlled, 
sequential-group.
For TID dosing, GSK2982772 or placebo will be administered using a 7hr, 7hr and 10hr
dosing interval. For BID dosing, GSK2982772 or placebo will be administered using a 
12hr dosing interval. 
The impact of food on the PK of GSK2982772 will be investigated during the 14 Day 
repeat dose phase of the study (Part B) in Cohorts 2 and 3. On Days 1 to 14, subjects will 
fast for 8hr overnight. Breakfast will be served 2hr after dosing on Days 1 through 8, 10,

12 and 14. A standard breakfast will be served 30 minutes prior to dosing on Day 9, and a 
high fat breakfast will be served 30 minutes prior to dosing on Day 11. 
All of the Cohorts in this study will be double-blind with respect to the subjects, 
investigator and site staff (with the exception of the site pharmacist). The Sponsor, the 
GSK study team, will be unblinded throughout.
5.2.
Number of Participants
Sufficient number of healthy subjects will be enrolled, such that approximately 12 
subjects in each Cohort complete dosing and critical assessments. If subjects prematurely 
discontinue the study, additional replacement subjects may be randomized in order to 
guarantee that sufficient subjects are treated with GSK2982772 at any given dose before 
escalating to the following dose. Subjects that participate in Part A of the study cannot 
participate in Part B.
5.3.
Sentinel Dosing
Sentinel dosing will be employed within each dosing period in Part A of the study. The 
doses in the single-ascending dose portion of the study (Part A) will be staggered such 
that for each of the three treatment periods, on Day 1, two of the 12 subjects will be 
randomized to treatment (one subject will receive GSK2982772 and one subject will 
receive matched-placebo). Assuming 2 subjects are dosed on Day 1 and assuming 
adequate safety in the judgment of the Principal Investigator (e.g., vital signs, ECGs, and 
AEs) through approximately 24 hours after their last dose on Day 1, the remaining 
subjects may be randomized to dosing in that period. The doses in the repeat dose portion 
of the study (Part B) will be staggered such that for each treatment period on Day 1, two 
of the 12 subjects will be randomized to treatment (one subject will receive GSK2982772 
and one subject will receive matched-placebo) and dosed for at least 7 days before the 
rest of the cohort is randomized. If participants prematurely discontinue the study, 
additional replacement participants may be recruited and assigned to the same treatment 
sequence, at the discretion of the Sponsor in consultation with the investigator.

Scientific Rationale for Study Design
In Part A, each cohort will initially evaluate the safety, tolerability and PK of 
GSK2982772 administered for 1 day as a TID or BID dosing regimen (Cohort 1). 
In Part B, the 14-day TID or BID repeat dosing (Cohort 2, 3 and 4) was chosen since it 
will provide sufficient safety and tolerability data to bridge to longer duration studies 
with the recently achieved safety margins from the 13-week toxicology study in 
monkeys. In the previous FTiH study (200975), GSK2982772 was administered up to 
120 mg BID for 14 days and was well tolerated with no safety concerns identified. Please 
see GSK2982772 IB [GlaxoSmithKline Document Number 2014N204126_02].
Cohort 4, 360 mg BID dosing regimen, may only be evaluated if the results of a modified 
release (MR) formulation study (205017) being conducted in parallel with the current 
study indicate that a MR formulation is not feasible for GSK2982772. In which case a 
BID regimen using the current immediate release formulation may be taken forward in to
Phase 2a PoC studies. Additionally, Cohort 4 dose may be modified to include the 
repetition of a previous or lower TID or BID dose based on the results of the safety and 
tolerability review or if further characterization of the safety profile at a previously tested
dose is required.     
In the previous FTiH (Study 200975), the impact of a high-fat meal on the absorption of 
GSK2982772 was investigated following single dose administration of GSK2982772 at a 
dose of 40 mg. The rate and extent of absorption was similar in the fed state as compared 
to the fasted state, although there was evidence of a time lag in the absorption in the fed 
state, probably as a result of delayed gastric emptying. It is likely that higher doses to be 
used in this study will have a similar food effect to that observed at 40 mg. Therefore,
this study plans to evaluate the impact of food during the repeat dose phase in Cohorts 2 
and 3 rather than conducting a standalone single dose food effect PK study.
5.7.
Dose Justification
An adaptive dose-escalation approach, guided by the observed safety, tolerability and 
plasma PK exposure will be taken to allow an efficient evaluation of a range of doses 
above the 120 mg BID dose that was evaluated in the FTiH study.    
The initial starting dose planned is 120 mg TID and the maximum daily dose is 
anticipated to be approximately 720 mg administered as 240 mg TID and 360 mg BID.  
For doses of up to 120 mg BID, the pharmacokinetics of GSK2982772 are approximately 
linear. Please see GSK2982772 IB [GlaxoSmithKline Document Number 
2014N204126_02]. After attainment of  Cmax, at approximately 2 hours post-dose, 
GSK2982772 concentrations decline rapidly until about 12 hours post-dose, with a t1/2 of 
approximately 2 to 3 hours. The majority of the systemic exposure to GSK2982772 is 
observed within the first 12 hours after administration. Following repeat dosing of 
GSK2982772, there is no evidence of drug accumulation for either a QD or BID dosing 
regimen. The major circulating metabolite is an N-glucuronide which accounts for 
approximately 70% of drug related material in plasma. Since glucuronidation is a high

40
capacity clearance mechanism it is unlikely that the kinetics of GSK2982772 will become 
saturable with more frequent dosing nor at the higher doses planned in the current study.   
Due to the short half-life of GSK2982772 (~2-3 hr), it is expected that steady-state will 
be achieved by Day 2 of dosing and that negligible accumulation will be observed. 
Therefore, the PK safety margins described for Day 1 and for Day 14 of dosing will be 
similar. 
The predicted mean AUC(0-24) for the highest planned doses of 240 mg TID and 360 mg 
BID (40.2 μg*h/mL) approximates parity with the mean AUC(0-24) observed at the 
NOAEL (30 mg/kg/day) in the 13-week monkey toxicology study (48.4 μg*h/ml). Mean 
Cmax values for the 240 mg TID (3.21 μg/mL) and 360 mg BID (4.31 μg/mL) doses are 
predicted to be 1/4th and 1/3rd respectively, of the Cmax observed at the NOAEL (12.3 
μg/mL). The doses for Cohorts 2 and 3 may be adjusted based on PK/safety data from 
previous treatment periods. It is planned that the 95th percentile for the predicted 
AUC(0-24) values will not exceed the maximum AUC(0-24) value observed at the NOAEL
and for Cmax the 95th percentile will not exceed the mean Cmax and the NOAEL. The 
current predicted 5th -95th percentiles for AUC(0-24) and Cmax values using repeat dose PK 
data from FTiH study and mean/individual AUC(0-24) and Cmax values from the 13-week 
Monkey Study at 30 mg/kg/day (NOAEL) and 100 mg/kg/day are shown in Figure 2 and 
Figure 3, respectively.

Method of Treatment Assignment
On Day -1 or Day 1 participants will be assigned a unique number (randomization 
number) in ascending numerical order. The randomization number encodes the 
participant’s assignment to either GSK2982772 or placebo, according to the 
randomization schedule generated prior to the study by the Statistics Department at GSK, 
using validated internal software. 
All participants will be centrally randomized using an Interactive Voice/Web Response 
System (IVRS/IWRS). Before the study is initiated, the telephone number and call-in 
directions for the IVRS and/or the log in information & directions for the IWRS will be 
provided to the site.
Study treatment will be dispensed at the study visits summarized in SoA. Each participant 
will be dispensed blinded study treatment, labelled with his/her unique randomization 
number, throughout the study. Returned study treatment should not be re-dispensed to the 
participants
In all four cohorts, subjects will be randomized in a 3:1 ratio to either GSK2982772 or 
placebo. In Cohort 1, the subjects will be randomized to one of four sequences (ABC, 
ABP, APC, PBC), where the treatments are:
A
120 mg TID
B
240 mg TID

The planned dose levels are defined in Section 5.1.
The randomisation will reflect the fact that at least 2 of the 12 subjects (one subject will 
receive GSK2928772 and one subject will receive matched-placebo) will be dosed first 
(on Day 1) in each part to enable dose staggering. 
Once a treatment allocation number has been assigned to a subject, it cannot be 
reassigned to any other subject.
7.3.
Blinding
This will be a double blind (sponsor-unblinded) study and the following will apply:

The Investigator or treating physician will remain blinded to each participant’s 
assigned study treatment throughout the course of the study. In order to maintain 
this blind, an otherwise uninvolved 3rd party will be responsible for the 
reconstitution and dispensation of all study treatment and will endeavour to 
ensure that there are no differences in time taken to dispense following 
randomization

This 3rd party will instruct the participant to avoid discussing the taste, dosing 
frequency, or packaging of the study treatment with the investigator

Unblinded monitors and in the event of a Quality Assurance audit, the auditor(s) 
will be allowed access to un-blinded study treatment records at the site(s) to 
verify that randomization/dispensing has been done accurately.

The IVRS/IWRS will be programmed with blind-breaking instructions.

In case of an emergency, the investigator has the sole responsibility for 
determining if unblinding of a participant’s treatment assignment is 
warranted. Participant safety must always be the first consideration in making 
such a determination.

If the investigator decides that unblinding is warranted, the investigator should 
make every effort to contact GSK prior to unblinding a participant’s treatment 
assignment unless this could delay emergency treatment of the participant.

If a participant’s treatment assignment is unblinded, GSK must be notified 
within 24 hours after breaking the blind.

The date and reason that the blind was broken must be recorded in the source 
documentation and Case Report Form (CRF), as applicable.

A subject will be withdrawn if the subject’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 subject 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 subject’s treatment assignment, may be sent to 
investigators in accordance with local regulations and/or GSK policy.
7.4.
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 SRM.

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.
7.5.
Treatment Compliance

When the individual dose for a participant is prepared from a bulk supply, the 
preparation of the dose will be confirmed by a second member of the study site staff. 

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.
7.6.
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 
enrolment or receives during the study must be recorded along with:


reason for use

dates of administration including start and end dates


The Medical Monitor should be contacted if there are any questions regarding 
concomitant or prior therapy.
Participants must abstain from taking prescription or non-prescription 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.
7.7.
Treatment after the End of the Study
Subjects will not receive any additional treatment from GSK, or with GSK2982772, after 
completion of the study because only healthy volunteers are eligible for study 
participation.

Discontinuation of Study Treatment
8.1.1.
Dose Modification/Stopping Criteria
This protocol allows some alteration from the currently outlined dosing schedule, but the 
maximum total daily dose will not intentionally exceed the 13-week NOAEL exposure in 
monkeys. Currently, the highest planned dose is 720 mg/day of GSK2982772.
The decision to proceed to the next dose level of GSK2982772 in each part of this study 
will be made by the DEC, including the Medical Monitor and the Investigator and 
relevant clinical site staff (see Section 10.5) based on safety, tolerability, and preliminary 
PK data obtained in at least 6 subjects (through at least 24 hours post-dose) with at least 6
subjects having received active treatment (GSK2982772) at the prior 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 the PK criteria defined 
in Section 8.1.2.  Planned doses may also be repeated.
The Principal Investigator and the GSK Medical Monitor will review the following and 
dosing will be halted and progression to the next higher dose level stopped if:

One (1) or more subjects experience a SAE which has a reasonable possibility of 
relation to study drug.

Two (2) or more subjects experience a severe or clinically significant non-serious 
AE (based upon investigator judgment) which has a reasonable possibility of relation 
to study drug.

Two (2) or more subjects in a Part A cohort or 3 or more subjects in a Part B cohort 
experience the same AE of moderate severity which has a reasonable possibility of 
relation to study drug.

Consistent Common Terminology Criteria for Adverse Events (CTCAE) Nervous 
System AEs of any grade occur across subjects 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 MHRA (Medicines 
and Healthcare Products Regulatory Agency) for approval.
8.1.2.
Pharmacokinetic Dose Modification or Stopping Criteria
The 240 mg TID dose and/or the 360 mg BID dose in Cohorts 1, 3 and 4 may be adjusted 
up or down based on PK data from previous treatment periods. It is planned that the 95th
percentile for the predicted AUC(0-24) values will not exceed the maximum AUC(0-24)
value observed at the NOAEL and for Cmax the 95th percentile will not exceed the mean 
Cmax at the NOAEL.

The same QT correction formula must be used for each individual participant to 
determine eligibility for and discontinuation from the study (i.e., QTcF in this 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 QTcF, then QTcF
must be used for discontinuation of this individual participant as well.

53

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. If an 
ECG demonstrates a prolonged QTc, obtain 2 more ECGs over a brief period (5-10 
minutes), and then use the averaged QTc values of the 3 ECGs to determine whether 
the subject should be discontinued from the study.
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.
8.1.5.
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 becomes pregnant.

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 (See Section 8.1.3) or QTc stopping 
criteria (see Section 8.1.4) are met.

The participant experiences any signs of suicidal ideation or behaviour (See 
Section 9.3.6).
8.1.6.
Group Safety Stopping Criteria
In addition to the criteria specified above, AEs, SAEs, laboratory abnormalities, ECG 
abnormalities and changes in vital signs occurring across all randomized subjects will be 
regulatory reviewed by the Sponsor Safety Review Team (SRT) in order to ensure 
appropriate subject safety. Any changes to the study due to safety reasons will be 
promptly communicated to the appropriate Regulatory Authorities.
8.1.7.
Nervous System Stopping Criteria
The CNS observations in the 4-week GLP toxicology study in monkeys were found to be 
random, diverse, and unpredictable in monkeys (see Section 3.3.1).  There were no 
similar findings observed in the 13-week GLP toxicology study in monkeys.  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 subject will be determined based on clinical 
judgment, characteristics of the event and/or based upon changes from a baseline 
assessment.

2017N326600_01
CONFIDENTIAL
205184
54
The Principal Investigator and the GSK Medical Monitor will review all neurological 
events utilizing the CTCAE Nervous System criteria and dosing may be halted if and 
progression to the next higher dose level stopped as per Section 8.1.1.
A subject will be withdrawn from the study if:

A Grade 3 or greater CTCAE Nervous System finding is observed or a significant 
neurologic change from a subject’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 subject withdrawal.
Note:  Appendix 8 (Section 12.8) provides Guidance for Grading Adverse Events that is 
taken from the CTCAE Version 4.03.
8.1.8.
Rechallenge
8.1.8.1.
Study Treatment Restart or Rechallenge
Study treatment restart or rechallenge after liver chemistry stopping criteria are met by 
any participant in this study is not allowed.
8.2.
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, 
behavioural, compliance or administrative reasons. The reason for withdrawal 
should be documented in the CRF.

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.
If a subject chooses to withdraw from the study after dosing, then the Investigator must 
make every effort to complete the follow-up assessments detailed in the SoA (Section 2).
8.3.
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:

2017N326600_01
CONFIDENTIAL
205184
55

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.

STUDY ASSESSMENTS AND PROCEDURES

Study procedures and their timing are summarized in the SoA. 

Protocol waivers or exemptions are not allowed 

Immediate safety concerns should be discussed with the sponsor immediately upon 
occurrence or awareness to determine if the 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 (e.g., 
blood count) and obtained before signing of ICF may be utilized for screening or 
baseline purposes provided the procedure met the protocol-specified criteria and was 
performed within the time frame defined in the SoA.

The maximum amount of blood collected from each 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.
9.1.
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 treatment (see Section 8). 
9.1.1.
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).

2017N326600_01
CONFIDENTIAL
205184
57

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 CRF not the AE section.

All SAEs will be recorded and reported to the sponsor or designee immediately 
and under no circumstance should this exceed 24 hours, as indicated in 
Appendix 4. The investigator will submit any updated SAE data to the sponsor 
within 24 hours of it being available.

Investigators are not obligated to actively seek AEs or SAEs 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.
9.1.2.
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. 
9.1.3.
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, and non-serious AEs of special 
interest (as defined in Section 3.3.1), will be followed until the event is resolved, 
stabilized, otherwise explained, or the participant is lost to follow-up (as defined in 
Section 8.3). Further information on follow-up procedures is given in Appendix 4.
9.1.4.
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, 
IRB/ 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 

2017N326600_01
CONFIDENTIAL
205184
58
sponsor will review and then file it along with the Investigator’s Brochure and 
will notify the IRB/IEC, if appropriate according to local requirements.
9.1.5.
Pregnancy

Details of all pregnancies in female participants and, if indicated, 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 Appendix 5.

Abnormal pregnancy outcomes (e.g., spontaneous abortion, fetal death, stillbirth, 
congenital anomalies, ectopic pregnancy) are considered SAE.
9.2.
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 or treating physician should:
1.
Contact the Medical Monitor immediately.
2.
Closely monitor the participant for AE/SAE and laboratory abnormalities until 
GSK2982772 can no longer be detected systemically (at least 2 days for 
GSK2982772).
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.
9.3.
Safety Assessments
Planned time points for all safety assessments are provided in the SoA.
9.3.1.
Physical Examinations

A complete physical examination will include, at a minimum, assessments of the 
Skin, Cardiovascular, Respiratory, Gastrointestinal and Neurological systems.
Height (screening only) 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.

2017N326600_01
CONFIDENTIAL
205184
59
9.3.2.
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 
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 8.2),

may result in referral to a specialist.
9.3.3.
Vital Signs

Temperature, pulse rate, respiratory rate, and blood pressure will be assessed.

Blood pressure and pulse measurements will be assessed in a supine position
with a completely automated device. Manual techniques will be used only if an 
automated device is not available.

Blood pressure and pulse measurements should be preceded by at least 5 
minutes of rest for the participant in a quiet setting without distractions (e.g., 
television, cell phones).

Vital signs will be measured in a supine position after 5 minutes’ rest and will 
include temperature, systolic and diastolic blood pressure, and pulse and 
respiratory rate.

In Part A and B on Day 1, vital signs (to be taken before blood collection for 
laboratory tests) will consist of 3 pulse and 3 blood pressure measurements pre-
dose on Day 1 (3 consecutive blood pressure readings will be recorded at 
intervals of at least 1 minute). The average of the 3 blood pressure readings will 
be recorded on the CRF.
9.3.4.
Electrocardiograms

Triplicate 12-lead ECG will be obtained as outlined in the SoA (see Section 2) 
using an ECG machine that automatically calculates the heart rate and measures 
PR, QRS, QT, and QTc intervals. Refer to Section 8.1.4 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 with at least 2 
minutes but no more than 10 minutes apart. 

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.

9.3.5.
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 
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 SRM and the SoA.
9.3.6.
Suicidal Risk Monitoring
GSK2982772 is considered to be a CNS-active drug.  There is some concern that some 
CNS-active drugs may be associated with an increased risk of suicidal thinking or 
behaviour when given to some subjects. Although this drug has not been shown to be 
associated with an increased risk of suicidal thinking or behaviour when given to healthy 
volunteers, GSK considers it important to monitor for such events before or during 
clinical studies with compounds such as this.
Participants being treated with GSK2982772 should be monitored appropriately and 
observed closely for suicidal ideation and behaviour or any other unusual changes in 
behaviour. All subjects who experience signs of suicidal ideation or behaviour must 
immediately be discontinued from study medication.
Families and caregivers of participants being treated with GSK2982772 should be alerted 
about the need to monitor participants for the emergence of unusual changes in 
behaviour, as well as the emergence of suicidal ideation and behaviour and to report such 
symptoms immediately to the study investigator.
At screening and baseline (pre-dose Day 1) in Part B only, the Baseline/Screening 
assessment of suicidal ideation and behaviour and treatment emergent suicidal ideation 
and behaviour will be monitored during study 205184 using C-SSRS. At Days 7 and 17 
of the study, the ‘Since Last Visit C-SSRS’ will be completed. Refer to Section 2, SoA,
for more information.
Subjects who answer ‘Yes’ to any suicidal behaviour or ‘Yes’ to suicidal ideation 
Questions 4 or 5 will be referred to their General Practitioner (GP) or appropriate 

2017N326600_01

61
psychiatric care. The medical monitor will be notified. If appropriate, an AE or SAE 
should be reported (see Section 9.1). In addition, the investigator should complete a 
Possible Suicidality Related Adverse Event (PSRAE) form to collect detailed information 
on the circumstances of the reported AEs which, in the investigator’s opinion, are 
possibly suicidality-related. These may include, but are not limited to, an event involving 
suicidal ideation, a preparatory act toward imminent suicidal behaviour, a suicide 
attempt, or a completed suicide.
9.4.
Pharmacokinetics
9.4.1.
Blood Sample Collection
Blood will be collected into EDTA tubes and processed to plasma for PK analysis of 
GSK2982772 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.  
Blood will be collected into EDTA tubes and processed to plasma for PK analysis of M8 
(GSK3562183) and M9 (GSK2997852). This will be collected at the time points 
indicated in Section 2, SoA Tables. The actual date and time of each blood sample 
collection will be recorded. 
Blood will be collected into EDTA tubes and processed to plasma for
4β-hydroxycholesterol and cholesterol. This will be collected at the time points indicated 
in Section 2, SoA Tables. The actual date and time of each blood sample collection will 
be recorded. 
Details of blood sample collection, processing, storage and shipping procedures are 
provided in the SRM. 
9.4.2.
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 GSK2982772
will be determined in plasma samples, and concentrations of M8 (GSK3562183) and M9 
(GSK2997852) will be determined in select plasma samples, 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 GSK2982772 (or M8 [GSK3562183] and 
M9 [GSK2997852] as indicated above), any remaining plasma sample may be analysed 
for any compound-related material and the results may be reported as part of this study or 
under a separate PTS-IVIVT, 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.

Plasma Sample for CYP3A4 Enzyme Activity
Plasma derived from select PK blood samples in Part B (as in the SoA Table), will be 
analyzed for 4β-hydroxycholesterol and cholesterol as a potential in vivo marker of 
CYP3A4 enzyme activity. Samples collected pre-treatment and at steady-state will be 
compared to evaluate this potential marker.
Details on CYP3A4 enzyme activity marker plasma sample collection, processing, 
storage and shipping procedures are provided in the SRM.
Baseline and Day 14, post-treatment plasma samples will be analyzed using a validated, 
specific, and sensitive liquid chromatography–mass spectrometry (LC-MS/MS) method 
to determine concentrations of 4β-hydroxycholesterol and total cholesterol.  A 
comparison will be made between the ratio of 4β-hydroxycholesterol : cholesterol at 
baseline and on Day 14 to assess potential changes in CYP3A4 enzyme activity 
following GSK2982772 treatment.
Analysis will be performed at a bioanalytical site (to be detailed in the SRM) under the 
control of PTS-IVIVT and Third Party Resource, GlaxoSmithKline.
9.5.
Pharmacodynamics
Pharmacodynamic parameters are not evaluated in this study.
9.6.
Genetics
A blood sample for DNA isolation will be collected from participants who have 
consented to participate in the genetics analysis component of the study. Participation is 
optional. Participants who do not wish to participate in the genetic research may still 
participate in the study.
In the event of DNA extraction failure, a replacement genetic blood sample may be 
requested from the participant. Signed informed consent will be required to obtain a 
replacement sample unless it was included in the original consent.
See Appendix 6 for Information regarding genetic research. Details on processes for 
collection and shipment and destruction of these samples can be found in the Study 
Reference Manual.

STATISTICAL CONSIDERATIONS
The objectives of this study are to assess the safety and tolerability of single and repeat 
ascending doses of GSK2982772. No formal hypotheses will be tested.  
An estimation approach will be used to describe PK of GSK2982772, where point 
estimates and corresponding 90% confidence intervals will be constructed.
10.1.
Sample Size Determination
No statistical techniques were used to calculate the sample size, and sample size is based 
on feasibility.
The primary objective of the study is safety, where the number of safety events are of 
interest.  A maximum of 9 subjects will receive each active dose and; therefore, if 0/9 of 
a particular safety event in the GSK2982772 group is observed, the upper limit of the 
exact 95% CI indicates that a true incidence rate of 33.6% could not be ruled out.  
Whereas if 1/9 of the same safety event in the GSK2982772 group is observed, the upper 
limit of the exact 95% CI indicates that a true incidence rate of 48.2% could not be ruled 
out.
Using a Bayesian approach to determine the confidence interval around an observed 
safety event, we would assume a flat Beta (1,1) prior, and if we were to observe one
safety event in 9 then the posterior distribution would be Beta (2, 9), as outlined below:
Bayesian Approach to Determine Confidence in a Safety Event.
Thus, we can be 95% certain that the true probability of the safety event lies between 
0.04 and 0.39.

Pharmacokinetic Parameters
To date the pharmacokinetics of GSK2982772 have been studied up to 120 mg BID. The 
maximum between-subject coefficient of variation (CVb) for AUC(0-τ) and Cmax observed 
in study 200975 was 27.1 and 36.1 respectively. 
Based on these estimates of variability, slightly more conservative for a cross-over study
and a sample size of 9 completers in Cohort 2, it is estimated that the lower and upper 
bounds of the 90% confidence interval for the means of AUC and Cmax will be within 
approximately 17.9% and 24.2% of the point estimate, respectively.
10.2.
Sample Size Sensitivity
A sample size sensitivity analysis has been conducted on the primary endpoint, to 
investigate different safety event rates. If the number of subjects who completed each 
active dose, then the true incidence rates of safety events that could not be ruled out (as 
outlined in Section 10.1 Sample Size Determination) would change.  These changes are 
outlined in Table 1:

(exp(SD2) -1)) will be provided, where the SD is the standard deviation of 
log-transformed data.
10.4.3.
Other Analyses
Descriptive statistics (n, arithmetic mean, standard deviation, 95% CI, minimum, median 
and maximum) of circulating glucuronide metabolite (M8; GSK3562183) and des-methyl 
metabolite will be investigated in healthy subjects after single-day and repeat dosing of 
GSK2982772. 
10.4.4.
Interim Analyses
An interim analysis may be performed during the study on completed cohorts in Part A 
and Part B of the study to aid internal decision making only. There will be no changes to 
the study design or planned number of subjects in future cohorts as a result of the interim 
analysis.
For Parts A and B of the study, interim PK analyses will be performed on plasma 
GSK2982772 concentration-time data generated during the conduct of this study.
The decision to proceed to higher dose strengths will be made by the DEC based on 
assessment of safety, tolerability and pharmacokinetic data at the preceding dose. The 
exception to this will be in Part A where only a safety assessment (not PK) for the 120 
mg TID dose will be performed. To date, the PK of GSK2982772 has been well-
characterised up to 120 mg BID in the FTiH study and the 120 mg TID for Part A 
represents a 50% increase in dose where PK simulations are predictable. This analysis 
can include review of individual subject data, summaries, graphical presentations and/or 
statistical analysis.
The RAP will describe the planned interim analyses in greater detail.
10.5.
Dose Escalation Committee
The decision to proceed to the next dose level of GSK2982772 in each Cohort will be 
made by a DEC consisting of the Principal Investigator (or appropriate designee), 
Medical Monitor, GSK Clinical Investigational lead and/or Study Team Leader, GSK 
Pharmacokineticist, a GSK GCSP representative and GSK Statistician. All GSK 
personnel including the GSK Statistician and the GSK Pharmacokineticist will remain 
unblinded throughout the course of the study.

For Part A, dose escalation decisions will be based on data obtained from 6 or more 
subjects receiving GSK2982772 at the prior dose level. The review of the data set will 
consist at a minimum of: listings of all AEs, clinical laboratory results, flagged vital 
signs, flagged findings during continuous cardiac monitoring (telemetry), ECG and PK 
results derived from 24-hour plasma profiles.
The decision and selection of dose to proceed to Part B, will be made by the DEC based 
on safety, tolerability, and PK data from the same dose levels evaluated in Part A.  
For Part B, dose escalation decisions will be based on data obtained from 6 or more 
subjects receiving GSK2982772 at the prior dose level. The review of the data set will 
consist at a minimum of: listings of all AEs, clinical laboratory results, flagged vital 
signs, flagged findings during continuous cardiac monitoring (telemetry) and ECG 
findings through Day 16 of the previous cohorts(s) in Part B. Also included will be any 
PK results derived through at least Day 7 of the previous cohort(s).

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 assessmentse.g.eg, 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 
leads to the procedure is the AE.

Situations in which an untoward medical occurrence did not occur (social and/or 

2017N326600_01
CONFIDENTIAL
205184
80
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 fulfils any other serious criteria, the event is 
serious. When in doubt as to whether “hospitalization” occurred or was necessary, the AE 
should be considered serious.
Hospitalization for elective treatment of a pre-existing condition that did not worsen from 
baseline is not considered an AE.
d.
Results in persistent disability/incapacity

The term disability means a substantial disruption of a person’s ability to conduct 
normal life functions.

This definition is not intended to include experiences of relatively minor medical 
significance such as uncomplicated headache, nausea, vomiting, diarrhoea, influenza, 
and accidental trauma (e.g., sprained ankle) which may interfere with or prevent 
everyday life functions but do not constitute a substantial disruption.
e.
Is a congenital anomaly/birth defect
f.
Other situations:

Medical or scientific judgment should be exercised in deciding whether SAE 
reporting is appropriate in other situations such as important medical events that may 
not be immediately life-threatening or result in death or hospitalization but may 
jeopardize the participant or may require medical or surgical intervention to prevent 

2017N326600_01
CONFIDENTIAL
205184
81
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.

2017N326600_01
CONFIDENTIAL
205184
82
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.

Reporting of SAE to GSK
SAE Reporting to GSK via Paper CRF

Email transmission of the SAE paper CRF is the preferred method to transmit this 
information to the medical monitor or the SAE coordinator.

In rare circumstances and in the absence of email 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
Woman of Childbearing Potential (WOCBP)
A woman is considered fertile following menarche and until becoming post-menopausal 
unless permanently sterile (see below)
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 enrolment.
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 treatment phase and 
until at least 90 days after the last administration of study drug: 

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 and recommend subject or partner use of an 
additional method of contraception with a failure rate of <1% per year as 

2017N326600_01
CONFIDENTIAL
205184
85
described in Table 4 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 

In addition, male participants must refrain from donating sperm for duration of 
study and for 90 days after study completion or from last dose
Female participants
Female participants of childbearing potential are eligible to participate if they agree to 
use a highly effective method of contraception consistently and correctly as described in 
Table 4 for a minimum of 28 days prior to the first dose of study drug and until at least 30 
days after the last administration of study drug. For female particpants using a hormonal 
method of contraception, partner use of male condoms is also required during the 
treatment period and until at least 28 days after the last administration of study drug.

ovulationb

Intrauterine device (IUD)

Intrauterine hormone-releasing system (IUS)

bilateral tubal occlusion
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 

2017N326600_01
CONFIDENTIAL
205184
86
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 the use of a male condom should be utilized during the treatment period 
and for at least 30 days after the last dose of study treatment.
Pregnancy Testing

WOCBP should only be included after a confirmed menstrual period and a negative 
highly sensitive serum pregnancy test 

Additional pregnancy testing at admission to each study period and at the follow-up 
visit.

Pregnancy testing will be performed whenever a menstrual cycle is missed or when 
pregnancy is otherwise suspected.

Pregnancy testing, with a sensitivity of 25 mIU/mL will be performed using the test 
kit approved by the sponsor and in accordance with instructions provided in its 
package insert.
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.

Female Participants who become pregnant

Investigator will collect pregnancy information on any female participant, who 
becomes pregnant while participating in this study. 

Information will be recorded on the appropriate form and submitted to GSK within 
24 hours of learning of a participant's pregnancy. 

Participant will be followed to determine the outcome of the pregnancy. The 
investigator will collect follow up information on participant and neonate, which will 
be forwarded to GSK Generally, follow-up will not be required for longer than 6 to 8 
weeks beyond the estimated delivery date.  

Any termination of pregnancy will be reported, regardless of fetal status (presence or 
absence of anomalies) or indication for procedure. 

While pregnancy itself is not considered to be an AE or SAE, any pregnancy 
complication or elective termination of a pregnancy will be reported as an AE or 
SAE. 

A spontaneous abortion is always considered to be an SAE and will be reported as 
such.  

Any SAE occurring as a result of a post-study pregnancy which is considered 
reasonably related to the study treatment by the investigator, will be reported to GSK
as described in Appendix 4. While the investigator is not obligated to actively seek 
this information in former study participants, he or she may learn of an SAE through 
spontaneous reporting. 
Any female participant who becomes pregnant while participating will discontinue study 
treatment.

Appendix 6: Genetics
USE/ANALYSIS OF DNA

Genetic variation may impact a participant’s response to therapy, susceptibility, 
severity and progression of disease. Variable response to therapy may be due to 
genetic determinants that impact drug absorption, distribution, metabolism, and 
excretion; mechanism of action of the drug; disease etiology; and/or molecular 
subtype of the disease being treated. Therefore, where local regulations and IRB/IEC 
allow, a blood sample will be collected for DNA analysis.

DNA samples will be used for research related to GSK2982772 or immuno-
inflammatory and related diseases. They may also be used to develop tests/assays 
including diagnostic tests) related to GSK2982772 (or study treatments of this drug 
class) and immuno-inflammatory diseases. Genetic research may consist of the 
analysis of one or more candidate genes or the analysis of genetic markers 
throughout the genome [or analysis of the entire genome] (as appropriate)

DNA samples will be analyzed for UDP-glucuronosyltransferase 1-9 family, 
polypeptide A cluster enzyme that is encoded by the UGT1A9 gene complex.  
Additonal analyses may be conducted if it is hypothesized that this may help further 
understand the clinical data. 

The samples may be analyzed as part of a multi-study assessment of genetic factors 
involved in the response to GSK2982772 or study treatments of this class. The 
results of genetic analyses may be reported in the clinical study report or in a 
separate study summary.

The sponsor will store the DNA samples in a secure storage space with adequate 
measures to protect confidentiality. 

The samples will be retained while research on GSK2982772 (or study treatments of 
this class) continues but no longer than 15 years after the last subject last visit or 
other period as per local requirements.

Amendment 02 Republishing 26-Feb-2018
Overall Rationale for the Amendment:
Due to a number of asymptomatic, non-serious and self-limiting cardiac arrhythmias
observed in Cohorts 1 and 2 prompting a temporary dosing hold, the 120 mg TID for 14 
days will be repeated in Cohort 3. The randomization ratio has been changed to 9:5 
(Active:Placebo) in the remaining Cohorts of Part B (Cohorts 3, 4 and 5) to provide a 
more balanced comparison between subjects on active and placebo. Furthermore, 24 hour 
Holter monitoring will now be conducted at the screening visit to better understand the 
background telemetry patterns of each subject prior to the start of dosing.
Two additional PK timepoints will be collected on Day 1 in Cohorts 3 and 4 to enable the 
Cmax to be determined following the second dose of the day.
In addition, further administrative clarifications have been made.

The Study Design schematic has 
been updated to add Cohort 3 and 
adjust the randomization ratio from 
3:1 to 9:5 in Cohorts 3, 4 and 5.
The Type and Number of 
Participants has been raised to 14 
subjects in each Cohort 3, 4 and 5, 
which has been reflected in the 
Treatment Groups Table.
Figure 1 Study Design has been 
updated to add an additional 
Cohort and adjust the 
randomization ratio from 3:1 to 9:5 
in Cohorts 3, 4 and 5.
The text has been edited to state 
that there will be 12 subjects in 
each Cohort 1 and Cohort 2 and 14 
subjects in each of Cohorts 3, 4
and 5.
The wording has been updated 
such that sentinel dosing will take 
place in all Cohorts, except Cohort 
3.
The additional Cohort (3) has been 
included in the rationale for Part B 
of the study.
The randomization ratio has been 
changed from 3:1 to 9:5 in Cohorts 
3, 4 and 5. No sentinel dosing will 
take place in Cohort 3.
The title for Table 1 has been 
updated to Safety Events - Sample 
Size Sensitivity on Active Dose.
Except for the two sentinel subjects in 
Cohort 2, dosing was not completed in this 
Cohort because of the temporary halt, 
therefore this dose level will be repeated 
under the new Cohort designation of Cohort 
3.
Cohort 3 will not require sentinel dosing 
since this was completed in the original 
dose level (Cohort 2).
The randomization ratio for Cohorts 3, 4
and 5 has changed from 3:1 to 9:5, with the 
overall number of subjects participating in 
each of these Cohorts increasing from 12 to 
14. This will provide a more balanced 
review with the number of subjects on 
active and placebo.

Objective
Endpoint

To assess potential effect of repeat doses 
of GSK2982772 on CYP3A4 enzyme 
activity.

Plasma 4β-hydroxycholesterol to 
cholesterol ratio pre-treatment and following 
14 days of repeat dosing of GSK2982772.
Exploratory

To investigate the levels of circulating 
glucuronide metabolite (M8; GSK3562183)
and desmethyl metabolite (M9; 
GSK2997852) in healthy subjects after 
single-day and repeat dosing of 
GSK2982772.

Quantify M8 (GSK3562183) and M9 
(GSK2997852) in select plasma PK 
samples after single-day dosing and at pre-
dose and 2 hr following Day 14 of repeat 
dosing of GSK2982772.
Overall Design:
This is a single-centre, randomized, double-blind (sponsor-unblinded), placebo-controlled 
study to evaluate the safety, tolerability and pharmacokinetics of GSK2982772, in repeat 
oral doses in healthy subjects. The study design schematic is depicted in the Figure
below:

Type and Number of Participants:
Healthy volunteer subjects will be enrolled, such that up to approximately 12 subjects (9 
active, 3 placebo) in Cohorts 1 and 2 (up to approximately 24 in total) and 14 subjects (9 
active, 5 placebo) in Cohorts 3, 4 and 5 (up to approximately 42 in total) complete dosing 
and critical assessments. A subject is defined to have completed the study when he/she 
has attended all study visits.
Sentinel dosing will be employed within each Cohort for both Part A and Part B of the 
study, except Cohort 3 since this was completed in the original dose level (Cohort 2). The 
doses in the single-ascending dose portion of the study (Part A) will be staggered such 
that for each of the three treatment periods, on Day 1, two of the 12 subjects will be 
randomized to treatment (one subject will receive GSK2982772 and one subject will 
receive matched-placebo). Assuming 2 subjects are dosed on Day 1 and assuming 
adequate safety in the judgment of the Principal Investigator (e.g., vital signs, ECGs, and 
adverse events) through approximately 24 hours after their last dose on Day 1, the 
remaining subjects may be randomized to dosing in that period. The doses in the repeat 
dose portion of the study (Part B) will be staggered such that for each treatment period on 
Day 1, two of the 12 subjects in Cohort 2 and two of the 14 subjects in Cohorts 4 and 5
will be randomized to treatment (one subject will receive GSK2982772 and one subject 
will receive matched-placebo) and dosed for at least 7 days before the rest of the cohort is 
randomized. Assuming 2 subjects are dosed on Day 1 to 7 and assuming adequate safety 
in the judgment of the Principal Investigator (e.g., vital signs, ECGs, and adverse events) 
through approximately Day 7, the remaining subjects may be randomized to dosing.
If subjects prematurely discontinue the study, additional replacement subjects may be 
randomized in order to guarantee that sufficient subjects are treated with GSK2982772 at 
any given dose before escalating to the following dose. Replacement subjects will be 
assigned to the same treatment sequence (Cohort 1) or treatment (Cohorts 2-4) and start 
from the period to be replaced at the discretion of the Sponsor and in consultation with 
the Principal Investigator.
Treatment Groups and Duration:
The study duration, including screening and follow-up, is not expected to exceed 
13 weeks for Part A and 8 weeks for Part B of the study.

SCHEDULE OF ACTIVITIES (SOA)
Protocol waivers or exemptions are not allowed with the exception of immediate safety 
concerns. Therefore, adherence to the study design requirements, including those 
specified in the Schedule of Activities (SoA) tables (Section 2.1 and Section 2.2), are 
essential and required for study conduct.
Supplementary study conduct information not mandated to be present in this protocol is 
provided in the Study Reference Manual (SRM). The SRM will provide the site 
personnel with administrative and detailed technical information that does not impact 
subject safety.
This section lists the procedures and parameters of each planned study assessment. The 
exact timing of each assessment is listed in the SoA tables (Section 2.1 and Section 2.2).
The following points must be noted:

If assessments are scheduled for the same nominal time, THEN the assessments 
should occur in the following order:
1. 12-Lead ECG
2. Vital Signs
3. Blood Draws
Note: The timing of the assessments should allow the blood draw to occur at the exact 
nominal time.

The timing and number of planned study assessments, including safety, 
pharmacokinetic, or other 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.

The change in timing or addition of time points for any planned study assessments 
must be documented in a Note to File, which is approved by the relevant GSK 
study team member and then archived in the study sponsor and site study files, 
but this will not constitute a protocol amendment.

No more than 500 mL of blood will be collected over the duration of the study, 
including any extra assessments that may be required.

The Institutional Review Board/Independent Ethics Committee (IRB/IEC) will be 
informed of any safety issues that require alteration of the safety monitoring 
scheme or amendment of the Informed Consent Form.
A table defining the allowed variance in timings of assessments without being considered 
a protocol deviation will be included in the SRM.

INTRODUCTION
3.1.
Study Rationale
The current study is being conducted to support administration of higher dose levels than 
initially studied in the First Time in Human (FTiH) study - 200975. The dose in the FTiH 
study was capped at 120 mg BID based on exposure margins with the no observable 
adverse effect limit (NOAEL) in the 28-day monkey toxicology study (10 mg/kg/day). 
Subsequently, a 13-week toxicity study in monkeys has completed which increased the 
NOAEL to 30 mg/kg/day which will allow for an approximate 4-fold increase in the 
safety margins, in terms of systemic exposure to GSK2982772. The current study is 
being conducted to explore administration of higher dose levels than achieved in the 
FTiH study to support subsequent Phase 2a Proof of Concept (PoC) studies and Phase 2b 
dose range studies in subjects with psoriasis (PsO), rheumatoid arthritis (RA) and 
ulcerative colitis (UC).
3.2.
Background
GSK2982772 is a first-in-class, highly selective, small molecule inhibitor of receptor-
interacting serine/threonine protein-1 (RIP1) kinase. RIP1 is a member of the receptor-
interacting serine/threonine kinase family containing an amino-terminal kinase domain, 
an intermediate domain and a carboxy-terminal death domain. RIP1 regulates 
inflammatory signalling in response to stimuli such as tumour necrosis factor (TNF) and 
ligands of the Toll-like receptor family in both kinase-dependent and -independent 
manners [Ofengeim, 2013]. Upon binding to its receptor, tumour necrosis factor receptor-
1 (TNFR1), TNFα triggers one of three distinct cellular fates; NFκB activation, apoptosis, 
or the more recently identified programmed necrosis [Ofengeim, 2013]. In addition, 
recent studies have shown that the programmed necrosis signalling complex also 
regulates the induction of certain cytokines. Although RIP1 serves as a key decision 
checkpoint for all three of these pathways, its kinase activity is only requisite for the 
initiation of programmed necrosis and pro-inflammatory cytokine production [Berger, 
2014]. The discovery of this newly defined inflammatory, programmed necrotic pathway 
calls into question the major contributor to human disease downstream of the TNFR1. As 
such, a RIP1 kinase inhibitor represents a novel, selective mechanism for the treatment of 
inflammatory conditions such as Crohn’s Disease, Plaque Psoriasis, and Rheumatoid 
Arthritis through multiple mechanisms, including the blockade of cell death, danger 
associated molecular pattern (DAMP)-driven inflammation and pro-inflammatory 
cytokine production.

Investigational Product (IP) GSK2982772
Central Nervous System (CNS) Effects
Non-Clinical Data:
In the 4-week GLP toxicology study, CNS 
findings were observed in 2/12 monkeys which 
were administered 100 or 300 mg/kg/day. CNS 
findings included uncoordination, irregular gait, 
trembling, hunched appearance and decreased 
activity. The NOAEL for this study was 
determined at 10 mg/kg/day.
In the 13-week GLP toxicology study, there were 
no CNS findings observed in monkeys 
administered 10, 30 or 100 mg/kg/day. The 
NOAEL for this study was determined at 30 
mg/kg/day.
Clinical Data:
A FTiH study with single ascending and multiple 
ascending dose study has been performed in 67 
healthy male volunteers to date (see IB 
[GlaxoSmithKline Document Number 
2014N204126_02]). No drug-associated CNS 
adverse events (AEs) were identified and no 
Serious AEs (SAEs) were reported.
Subject Selection:
Subjects with known history of significant 
neurologic disorders including but not limited to 
progressive multiple sclerosis (MS), Amyotrophic
lateral sclerosis (ALS), Alzheimer’s and dementia 
will be excluded. 
Individuals with potentially increased 
susceptibility for neurologic effects will be 
excluded based on medical history at screening.
Subject Monitoring:
Subjects will be monitored for standard CNS-
related AEs.

Potential Risk of Clinical Significance
Summary of Data/Rationale for Risk 
Mitigation Strategy
Immunosuppression
The possibility of immunosuppression, including 
an increase in the frequency and/or severity of 
infection, may result from the intended 
pharmacologic effect of GSK2982772. This may 
be enhanced in subjects taking other 
immunomodulating drugs or corticosteroids.
Clinical Data:
In the FTiH study, no SAEs were reported. One 
subject experienced an Adverse Event (AE) 
herpes zoster approximately 27 days after 
receiving his last dose with GSK2982772 or 
placebo. The blinded investigator determined this 
to be potentially drug-related.
Subject Selection:
Subjects with recurrent, chronic or active 
infections will be excluded from the study.
Subjects will be screened for TB, HIV, Hepatitis 
B and C, and excluded from the study if positive.
Investigators are expected to follow local and/or 
national guidelines with respect to vaccinations, 
including against influenza and pneumococcus.
Subject Monitoring:
Subjects will be monitored for signs of infection.
See Individual Safety Stopping Criteria for 
atypical or opportunistic infections (Section 
8.1.5).
Vaccinations
There is a theoretical risk that GSK2982772 
could decrease an individual’s immune response 
to vaccines or allow symptoms to develop 
following vaccination with a live vaccine when 
administered while on therapy.
Subject Selection:
Attenuated or live vaccines should not be 
administered to subjects from 30 days prior to 
the first dose of GSK2982772, during the study 
and for 5 half-lives plus 30 days (total 32 days) 
after GSK2982772 is discontinued.

Potential Risk of Clinical Significance
Summary of Data/Rationale for Risk 
Mitigation Strategy
If indicated, non-live vaccines (e.g. inactivated 
influenza vaccines) may be administered while 
receiving GSK2982772 based on a treating 
physician assessment of the benefit: risk (e.g., 
risk of theoretical decreased responsiveness).
Investigators will be expected to have followed 
local and/or national guidelines with respect to 
vaccinations, including against influenza and 
pneumococcus.
Respiratory
Non-clinical data:
In the single-dose Safety Cardiovascular and 
Respiratory Study in monkeys, a decrease in 
minute volume (MV) and respiratory rate was 
observed at all doses (10, 100, and 300 mg/kg).  
These findings were noted to be reversible and 
mild in severity.
In a 14-day repeat dose Safety Respiratory 
Study in monkeys, no respiratory effects on total 
pulmonary ventilation (MV) or respiratory rate 
were observed at doses of 1 or 10 mg/kg/day. 
See IB for GSK2982772 [GlaxoSmithKline 
Document Number 2014N204126_02].
Subject Monitoring:
Subjects should be monitored for standard 
respiratory-related AEs.
Vital signs will be monitored during study visits.

Potential Risk of Clinical Significance
Summary of Data/Rationale for Risk 
Mitigation Strategy
Clinical data:
In the FTiH study, repeat doses of GSK2982772 
up to 120 mg BID were administered x 14 days 
in 48 healthy male volunteers. Extensive 
respiratory monitoring with end-tidal CO2 
(ETCO2), oxygen saturation (SpO2) and 
nocturnal respiratory rate monitoring was 
performed.   No SAEs occurred, and no drug-
associated respiratory-related AEs were 
identified.
Suicidality
GSK2982772 is considered to be a CNS-active 
drug based on pre-clinical studies.
Clinical Data:
In the FTiH study, there have been some reports 
of lethargy, abnormal dreams and depressed 
mood. No events of suicidal ideation or 
behaviour or changes in behaviour were 
reported.
Subject Selection:
Subjects with a current history of Suicidal 
Ideation Behaviour (SIB) as measured using the 
Columbia Suicide Severity Rating Scale (C-
SSRS) or a history of attempted suicide will be 
excluded from the study.
Subject Monitoring:
Subjects should be monitored appropriately and 
observed closely for suicidal ideation and 
behaviour or any other unusual changes in 
behaviour.

personnel using the C-SSRS in all subjects.
Reproductive Toxicity
Non-Clinical Data:
In the rat embryofetal development study, there 
were no maternal or developmental toxicity at 
doses ≤200 mg/kg/day.
In the rabbit embryofetal development study, 
GSK2982772 was administered at doses of 0, 
10, 100, 300 or 600 mg/kg/day on gestation day 
7 to 19. No developmental toxicity was evident at 
doses up to 300 mg/kg/day.
Subject Selection:
Female subjects of childbearing potential will be 
included in this study only if they agree to use 
one of the highly effective methods of 
contraception beginning at least 28 days prior to 
first dose of study drug until 30 days after the last 
administration of study drug. Women using a 
hormonal contraceptive method will also be 
required to have partners use a male condom 
from the first dose of study drug and until the 
follow-up visit to avoid conception until at least 
30 days after the last administration of study 
drug.  
Male subjects with female partners of 
childbearing potential must agree to use male 
condoms to avoid conception for defined periods 
of time before first administration of study drug 
until 90 days after the last administration of study 
drug. It is also recommended that a male subject 
with a female partner of childbearing potential 
employ a highly effective contraceptive method 
throughout this same period of time.
Females of childbearing potential will undergo

Withdrawal Criteria:
If a female subject should become pregnant 
during the study, study medication should be 
discontinued. The subject will be followed to 
determine the outcome of the pregnancy. Any 
pregnancy complication or elective termination of 
a pregnancy will be reported as an AE or SAE.

Non-Clinical Data:
In vitro studies with GSK2982772 assessing 
potential drug-drug interactions with Cytochrome 
P450 3A4 (CYP3A4) substrates and P-
glycoprotein (Pgp) inhibitors were completed. To 
date, formal drug interaction studies in humans 
have not been performed with GSK2982772.
There is a low risk that GSK2982772 could be an

Benefit Assessment
The proposed study with GSK2982772 will be conducted in healthy volunteers; no 
medical benefit will be derived by volunteers’ participation. Subjects 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 GSK2982772 can be appropriately mitigated by the 
careful selection of study participants and the proposed safety monitoring procedures. As 
such, the risk to potential subjects is considered low. Routine safety and tolerability will 
be evaluated from reported 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 (Section 2) will allow for continuous medical monitoring for all 
subjects following the first dose in each treatment group. Subjects will only be discharged 
from the unit 48 hours post-dose if the Investigator deems it safe to do so.
Taking into account the measures taken to minimize risk to subjects participating in this 
study, the potential risks identified in association with GSK2982772 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 is a single-centre, randomized, double-blind (sponsor-unblinded), placebo-controlled 
study to evaluate the safety, tolerability and pharmacokinetics of GSK2982772, in repeat 
oral doses in healthy subjects. The study design schematic is depicted in Figure 1.
Figure 1
Study Design
*With Food Effect Treatment
This study is planned to include approximately 66 subjects and consists of 2 parts:

Part A (Cohort 1) – single ascending dose, randomized, placebo-controlled, 3-way 
crossover.  

Part B (Cohorts 2, 3, 4 and 5) – repeat dose, randomized, placebo-controlled, 
sequential-group.
For TID dosing, GSK2982772 or placebo will be administered using a 7hr, 7hr and 10hr
dosing interval. For BID dosing, GSK2982772 or placebo will be administered using a 
12hr dosing interval. 
The impact of food on the PK of GSK2982772 will be investigated during the 14 Day 
repeat dose phase of the study (Part B) in Cohorts 2, 3 and 4. On Days 1 to 14, subjects

will fast for 8hr overnight. Breakfast will be served 2hr after dosing on Days 1 through 8, 
10, 12 and 14. A standard breakfast will be served 30 minutes prior to dosing on Day 9, 
and a high fat breakfast will be served 30 minutes prior to dosing on Day 11. 
All of the Cohorts in this study will be double-blind with respect to the subjects, 
investigator and site staff (with the exception of the site pharmacist). The Sponsor, the 
GSK study team, will be unblinded throughout.
5.2.
Number of Participants
Sufficient number of healthy subjects will be enrolled, such that approximately 12 
subjects in Cohorts 1 and 2 and 14 subjects in Cohorts 3, 4 and 5 complete dosing and 
critical assessments. If subjects prematurely discontinue the study, additional replacement 
subjects may be randomized in order to guarantee that sufficient subjects are treated with 
GSK2982772 at any given dose before escalating to the following dose. Subjects that 
participate in Part A of the study cannot participate in Part B.
5.3.
Sentinel Dosing
Sentinel dosing will be employed within each dosing period in Part A of the study. The 
doses in the single-ascending dose portion of the study (Part A) will be staggered such 
that for each of the three treatment periods, on Day 1, two of the 12 subjects will be 
randomized to treatment (one subject will receive GSK2982772 and one subject will 
receive matched-placebo). Assuming 2 subjects are dosed on Day 1 and assuming 
adequate safety in the judgment of the Principal Investigator (e.g., vital signs, ECGs, and 
AEs) through approximately 24 hours after their last dose on Day 1, the remaining 
subjects may be randomized to dosing in that period. The doses in the repeat dose portion 
of the study (Part B) will be staggered such that for each treatment period on Day 1, two 
subjects in each Cohort, except Cohort 3 since this was completed in the original dose 
level (Cohort 2), will be randomized to treatment (one subject will receive GSK2982772 
and one subject will receive matched-placebo) and dosed for at least 7 days before the 
rest of the cohort is randomized. If participants prematurely discontinue the study, 
additional replacement participants may be recruited and assigned to the same treatment 
sequence, at the discretion of the Sponsor in consultation with the investigator.
5.4.
Dose Escalation Decisions
The decision to proceed to the next dose level of GSK2982772 within the study will be 
made by a Dose Escalation Committee (DEC) consisting of Principal Investigator, or 
delegate, and other relevant GSK clinical staff (See Section 10.5).
5.5.
Participant and Study Completion
A participant is considered to have completed the study if he/she has completed all 
phases of the study including the last scheduled procedure shown in the SoA (Section 2).
The end of the study is defined as the date of the last visit of the last participant in the 
study or last scheduled procedure shown in the SoA for the last participant in the trial 
globally.

5.6.
Scientific Rationale for Study Design
In Part A, each cohort will initially evaluate the safety, tolerability and PK of 
GSK2982772 administered for 1 day as a TID or BID dosing regimen (Cohort 1). 
In Part B, the 14-day TID or BID repeat dosing (Cohort 2, 3, 4 and 5) was chosen since it 
will provide sufficient safety and tolerability data to bridge to longer duration studies 
with the recently achieved safety margins from the 13-week toxicology study in 
monkeys. In the previous FTiH study (200975), GSK2982772 was administered up to 
120 mg BID for 14 days and was well tolerated with no safety concerns identified. Please 
see GSK2982772 IB [GlaxoSmithKline Document Number 2014N204126_02].
Cohort 5, 360 mg BID dosing regimen, may only be evaluated if the results of a modified 
release (MR) formulation study (205017) being conducted in parallel with the current 
study indicate that a MR formulation is not feasible for GSK2982772. In which case a 
BID regimen using the current immediate release formulation may be taken forward in to
Phase 2a PoC studies. Additionally, Cohort 5 dose may be modified to include the 
repetition of a previous or lower TID or BID dose based on the results of the safety and 
tolerability review or if further characterization of the safety profile at a previously tested
dose is required.     
In the previous FTiH (Study 200975), the impact of a high-fat meal on the absorption of 
GSK2982772 was investigated following single dose administration of GSK2982772 at a 
dose of 40 mg. The rate and extent of absorption was similar in the fed state as compared 
to the fasted state, although there was evidence of a time lag in the absorption in the fed 
state, probably as a result of delayed gastric emptying. It is likely that higher doses to be 
used in this study will have a similar food effect to that observed at 40 mg. Therefore,
this study plans to evaluate the impact of food during the repeat dose phase in Cohorts 2, 
3 and 4 rather than conducting a standalone single dose food effect PK study.
5.7.
Dose Justification
An adaptive dose-escalation approach, guided by the observed safety, tolerability and 
plasma PK exposure will be taken to allow an efficient evaluation of a range of doses 
above the 120 mg BID dose that was evaluated in the FTiH study.    
The initial starting dose planned is 120 mg TID and the maximum daily dose is 
anticipated to be approximately 720 mg administered as 240 mg TID and 360 mg BID.  
For doses of up to 120 mg BID, the pharmacokinetics of GSK2982772 are approximately 
linear. Please see GSK2982772 IB [GlaxoSmithKline Document Number 
2014N204126_02]. After attainment of Cmax, at approximately 2 hours post-dose, 
GSK2982772 concentrations decline rapidly until about 12 hours post-dose, with a t1/2 of 
approximately 2 to 3 hours. The majority of the systemic exposure to GSK2982772 is 
observed within the first 12 hours after administration. Following repeat dosing of 
GSK2982772, there is no evidence of drug accumulation for either a QD or BID dosing 
regimen. The major circulating metabolite is an N-glucuronide which accounts for 
approximately 70% of drug related material in plasma. Since glucuronidation is a high

capacity clearance mechanism it is unlikely that the kinetics of GSK2982772 will become 
saturable with more frequent dosing nor at the higher doses planned in the current study.   
Due to the short half-life of GSK2982772 (~2-3 hr), it is expected that steady-state will 
be achieved by Day 2 of dosing and that negligible accumulation will be observed. 
Therefore, the PK safety margins described for Day 1 and for Day 14 of dosing will be 
similar. 
The predicted mean AUC(0-24) for the highest planned doses of 240 mg TID and 360 mg 
BID (40.2 μg*h/mL) approximates parity with the mean AUC(0-24) observed at the 
NOAEL (30 mg/kg/day) in the 13-week monkey toxicology study (48.4 μg*h/ml). Mean 
Cmax values for the 240 mg TID (3.21 μg/mL) and 360 mg BID (4.31 μg/mL) doses are 
predicted to be 1/4th and 1/3rd respectively, of the Cmax observed at the NOAEL (12.3 
μg/mL). The doses for Cohorts 2, 3, 4 and 5 may be adjusted based on PK/safety data 
from previous treatment periods. It is planned that the 95th percentile for the predicted 
AUC(0-24) values will not exceed the maximum AUC(0-24) value observed at the NOAEL
and for Cmax the 95th percentile will not exceed the mean Cmax and the NOAEL. The 
current predicted 5th -95th percentiles for AUC(0-24) and Cmax values using repeat dose PK 
data from FTiH study and mean/individual AUC(0-24) and Cmax values from the 13-week 
Monkey Study at 30 mg/kg/day (NOAEL) and 100 mg/kg/day are shown in Figure 2 and 
Figure 3, respectively.

Method of Treatment Assignment
On Day -1 or Day 1 participants will be assigned a unique number (randomization 
number) in ascending numerical order. The randomization number encodes the 
participant’s assignment to either GSK2982772 or placebo, according to the 
randomization schedule generated prior to the study by the Statistics Department at GSK, 
using validated internal software. 
All participants will be centrally randomized using an Interactive Voice/Web Response 
System (IVRS/IWRS). Before the study is initiated, the telephone number and call-in 
directions for the IVRS and/or the log in information & directions for the IWRS will be 
provided to the site.
Study treatment will be dispensed at the study visits summarized in SoA. Each participant 
will be dispensed blinded study treatment, labelled with his/her unique randomization 
number, throughout the study. Returned study treatment should not be re-dispensed to the 
participants
In Cohorts 1 and 2, subjects will be randomized in a 3:1 ratio to either GSK2982772 or 
placebo. In Cohorts 3, 4 and 5, subjects will be randomized in a 9:5 ratio to either
GSK2982772 or placebo. In Cohort 1, the subjects will be randomized to one of four
sequences (ABC, ABP, APC, PBC), where the treatments are:

CONFIDENTIAL
205184
47
A
120 mg TID
B
240 mg TID
C
360 mg BID
P
Placebo
The planned dose levels are defined in Section 5.1.
The randomization will reflect the fact that at least 2 of the 12 subjects in Cohorts 1 and 2 
and at least 2 of the 14 subjects in Cohort 4 and 5 (one subject will receive GSK2928772 
and one subject will receive matched-placebo) will be dosed first (on Day 1) in each part 
to enable dose staggering.
Once a treatment allocation number has been assigned to a subject, it cannot be 
reassigned to any other subject.
7.3.
Blinding
This will be a double blind (sponsor-unblinded) study and the following will apply:

The Investigator or treating physician will remain blinded to each participant’s 
assigned study treatment throughout the course of the study. In order to maintain 
this blind, an otherwise uninvolved 3rd party will be responsible for the 
reconstitution and dispensation of all study treatment and will endeavour to 
ensure that there are no differences in time taken to dispense following 
randomization

This 3rd party will instruct the participant to avoid discussing the taste, dosing 
frequency, or packaging of the study treatment with the investigator

Unblinded monitors and in the event of a Quality Assurance audit, the auditor(s) 
will be allowed access to un-blinded study treatment records at the site(s) to 
verify that randomization/dispensing has been done accurately.

The IVRS/IWRS will be programmed with blind-breaking instructions.

In case of an emergency, the investigator has the sole responsibility for 
determining if unblinding of a participant’s treatment assignment is 
warranted. Participant safety must always be the first consideration in making 
such a determination.

If the investigator decides that unblinding is warranted, the investigator should 
make every effort to contact GSK prior to unblinding a participant’s treatment 
assignment unless this could delay emergency treatment of the participant.

If a participant’s treatment assignment is unblinded, GSK must be notified 
within 24 hours after breaking the blind.

The date and reason that the blind was broken must be recorded in the source 
documentation and Case Report Form (CRF), as applicable.

2017N326600_03
CONFIDENTIAL
205184
48

A subject will be withdrawn if the subject’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 subject 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 subject’s treatment assignment, may be sent to 
investigators in accordance with local regulations and/or GSK policy.
7.4.
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 SRM.

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.
7.5.
Treatment Compliance

When the individual dose for a participant is prepared from a bulk supply, the 
preparation of the dose will be confirmed by a second member of the study site staff. 

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.

7.6.
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 
enrolment 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
The Medical Monitor should be contacted if there are any questions regarding 
concomitant or prior therapy.
Participants must abstain from taking prescription or non-prescription 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.
7.7.
Treatment after the End of the Study
Subjects will not receive any additional treatment from GSK, or with GSK2982772, after 
completion of the study because only healthy volunteers are eligible for study 
participation.

DISCONTINUATION CRITERIA
8.1.
Discontinuation of Study Treatment
8.1.1.
Dose Modification/Stopping Criteria
This protocol allows some alteration from the currently outlined dosing schedule, but the 
maximum total daily dose will not intentionally exceed the 13-week NOAEL exposure in 
monkeys. Currently, the highest planned dose is 720 mg/day of GSK2982772.
The decision to proceed to the next dose level of GSK2982772 in each part of this study 
will be made by the DEC, including the Medical Monitor and the Investigator and 
relevant clinical site staff (see Section 10.5) based on safety, tolerability, and preliminary 
PK data obtained in at least 6 subjects (through at least 24 hours post-dose) with at least 6
subjects having received active treatment (GSK2982772) at the prior 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 the PK criteria defined 
in Section 8.1.2. Planned doses may also be repeated.
The Principal Investigator and the GSK Medical Monitor will review the following and 
dosing will be halted and progression to the next higher dose level stopped if:

One (1) or more subjects experience a SAE which has a reasonable possibility of 
relation to study drug.

Two (2) or more subjects experience a severe or clinically significant non-serious 
AE (based upon investigator judgment) which has a reasonable possibility of relation 
to study drug.

Two (2) or more subjects in a Part A cohort or 3 or more subjects in a Part B cohort 
experience the same AE of moderate severity which has a reasonable possibility of 
relation to study drug.

Consistent Common Terminology Criteria for Adverse Events (CTCAE) Nervous 
System AEs of any grade occur across subjects 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 MHRA (Medicines 
and Healthcare Products Regulatory Agency) for approval.
8.1.2.
Pharmacokinetic Dose Modification or Stopping Criteria
The 240 mg TID dose and/or the 360 mg BID dose in Cohorts 1, 4 and 5 may be adjusted 
up or down based on PK data from previous treatment periods. It is planned that the 95th
percentile for the predicted AUC(0-24) values will not exceed the maximum AUC(0-24)
value observed at the NOAEL and for Cmax the 95th percentile will not exceed the mean 
Cmax at the NOAEL.

Liver Chemistry Stopping Criteria
Liver chemistry stopping and increased monitoring criteria have been designed to 
assure participant safety and evaluate liver event etiology.
Discontinuation of study treatment for abnormal liver tests is required when:

when in the presence of abnormal liver chemistries not meeting protocol-specified 
stopping rules, the investigator believes study treatment discontinuation is in the 
best interest of the participant. 
Phase I Liver Chemistry Stopping Criteria – Liver Stopping Event Algorithm

Report as an SAE if possible Hy’s Law case: ALT≥3xULN and  Bilirubin≥2xULN (>35% direct)  or 
INR>1.5, if measured*
Liver Safety Required Actions and Follow up Assessments Section can be found in
Appendix 7.
8.1.4.
QTc Stopping Criteria
A subject that meets either bulleted criterion based on the average of triplicate ECG 
readings will be withdrawn from study treatment.  

QTcF > 500 msec,

Change from baseline: QTc > 60 msec

The same QT correction formula must be used for each individual participant to 
determine eligibility for and discontinuation from the study (i.e., QTcF in this 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 QTcF, then QTcF
must be used for discontinuation of this individual participant as well.

2017N326600_03
CONFIDENTIAL
205184
52

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. If an 
ECG demonstrates a prolonged QTc, obtain 2 more ECGs over a brief period (5-10 
minutes), and then use the averaged QTc values of the 3 ECGs to determine whether 
the subject should be discontinued from the study.
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.
8.1.5.
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 becomes pregnant.

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 (See Section 8.1.3) or QTc stopping 
criteria (see Section 8.1.4) are met.

The participant experiences any signs of suicidal ideation or behaviour (See 
Section 9.3.6).
8.1.6.
Group Safety Stopping Criteria
In addition to the criteria specified above, AEs, SAEs, laboratory abnormalities, ECG 
abnormalities and changes in vital signs occurring across all randomized subjects will be 
regulatory reviewed by the Sponsor Safety Review Team (SRT) in order to ensure 
appropriate subject safety. Any changes to the study due to safety reasons will be 
promptly communicated to the appropriate Regulatory Authorities.
8.1.7.
Nervous System Stopping Criteria
The CNS observations in the 4-week GLP toxicology study in monkeys were found to be 
random, diverse, and unpredictable in monkeys (see Section 3.3.1).  There were no 
similar findings observed in the 13-week GLP toxicology study in monkeys.  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 subject 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 and dosing may be halted if and 
progression to the next higher dose level stopped as per Section 8.1.1.
A subject will be withdrawn from the study if:

A Grade 3 or greater CTCAE Nervous System finding is observed or a significant 
neurologic change from a subject’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 subject withdrawal.
Note:  Appendix 8 (Section 12.8) provides Guidance for Grading Adverse Events that is 
taken from the CTCAE Version 4.03.
8.1.8.
Rechallenge
8.1.8.1.
Study Treatment Restart or Rechallenge
Study treatment restart or rechallenge after liver chemistry stopping criteria are met by 
any participant in this study is not allowed.
8.2.
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, 
behavioural, compliance or administrative reasons. The reason for withdrawal 
should be documented in the CRF.

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.
If a subject chooses to withdraw from the study after dosing, then the Investigator must 
make every effort to complete the follow-up assessments detailed in the SoA (Section 2).
8.3.
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:

2017N326600_03
CONFIDENTIAL
205184
54

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.

STUDY ASSESSMENTS AND PROCEDURES

Study procedures and their timing are summarized in the SoA. 

Protocol waivers or exemptions are not allowed.

Immediate safety concerns should be discussed with the sponsor immediately upon 
occurrence or awareness to determine if the 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 (e.g., 
blood count) and obtained before signing of ICF may be utilized for screening or 
baseline purposes provided the procedure met the protocol-specified criteria and was 
performed within the time frame defined in the SoA.

The maximum amount of blood collected from each 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.
9.1.
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 treatment (see Section 8). 
9.1.1.
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).

2017N326600_03
CONFIDENTIAL
205184
56

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 CRF not the AE section.

All SAEs will be recorded and reported to the sponsor or designee immediately 
and under no circumstance should this exceed 24 hours, as indicated in 
Appendix 4. The investigator will submit any updated SAE data to the sponsor 
within 24 hours of it being available.

Investigators are not obligated to actively seek AEs or SAEs 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.
9.1.2.
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. 
9.1.3.
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, and non-serious AEs of special 
interest (as defined in Section 3.3.1), will be followed until the event is resolved, 
stabilized, otherwise explained, or the participant is lost to follow-up (as defined in 
Section 8.3). Further information on follow-up procedures is given in Appendix 4.
9.1.4.
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, 
IRB/ 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 

2017N326600_03
CONFIDENTIAL
205184
57
sponsor will review and then file it along with the Investigator’s Brochure and 
will notify the IRB/IEC, if appropriate according to local requirements.
9.1.5.
Pregnancy

Details of all pregnancies in female participants and, if indicated, 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 Appendix 5.

Abnormal pregnancy outcomes (e.g., spontaneous abortion, fetal death, stillbirth, 
congenital anomalies, ectopic pregnancy) are considered SAE.
9.2.
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 or treating physician should:
1.
Contact the Medical Monitor immediately.
2.
Closely monitor the participant for AE/SAE and laboratory abnormalities until 
GSK2982772 can no longer be detected systemically (at least 2 days for 
GSK2982772).
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.
9.3.
Safety Assessments
Planned time points for all safety assessments are provided in the SoA.
9.3.1.
Physical Examinations

A complete physical examination will include, at a minimum, assessments of the 
Skin, Cardiovascular, Respiratory, Gastrointestinal and Neurological systems.
Height (screening only) 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.

2017N326600_03
CONFIDENTIAL
205184
58
9.3.2.
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 
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 8.2),

may result in referral to a specialist.
9.3.3.
Vital Signs

Temperature, pulse rate, respiratory rate, and blood pressure will be assessed.

Blood pressure and pulse measurements will be assessed in a supine position
with a completely automated device. Manual techniques will be used only if an 
automated device is not available.

Blood pressure and pulse measurements should be preceded by at least 5 
minutes of rest for the participant in a quiet setting without distractions (e.g., 
television, cell phones).

Vital signs will be measured in a supine position after 5 minutes’ rest and will 
include temperature, systolic and diastolic blood pressure, and pulse and 
respiratory rate.

In Part A and B on Day 1, vital signs (to be taken before blood collection for 
laboratory tests) will consist of 3 pulse and 3 blood pressure measurements pre-
dose on Day 1 (3 consecutive blood pressure readings will be recorded at 
intervals of at least 1 minute). The average of the 3 blood pressure readings will 
be recorded on the CRF.
9.3.4.
Electrocardiograms

Triplicate 12-lead ECG will be obtained as outlined in the SoA (see Section 2) 
using an ECG machine that automatically calculates the heart rate and measures 
PR, QRS, QT, and QTc intervals. Refer to Section 8.1.4 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 with at least 2 
minutes but no more than 10 minutes apart. 

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.

9.3.5.
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 
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 SRM and the SoA.
9.3.6.
Suicidal Risk Monitoring
GSK2982772 is considered to be a CNS-active drug.  There is some concern that some 
CNS-active drugs may be associated with an increased risk of suicidal thinking or 
behaviour when given to some subjects. Although this drug has not been shown to be 
associated with an increased risk of suicidal thinking or behaviour when given to healthy 
volunteers, GSK considers it important to monitor for such events before or during 
clinical studies with compounds such as this.
Participants being treated with GSK2982772 should be monitored appropriately and 
observed closely for suicidal ideation and behaviour or any other unusual changes in 
behaviour. All subjects who experience signs of suicidal ideation or behaviour must 
immediately be discontinued from study medication.
Families and caregivers of participants being treated with GSK2982772 should be alerted 
about the need to monitor participants for the emergence of unusual changes in 
behaviour, as well as the emergence of suicidal ideation and behaviour and to report such 
symptoms immediately to the study investigator.
At screening and baseline (pre-dose Day 1) in Part B only, the Baseline/Screening 
assessment of suicidal ideation and behaviour and treatment emergent suicidal ideation 
and behaviour will be monitored during study 205184 using C-SSRS. At Days 7 and 17 
of the study, the ‘Since Last Visit C-SSRS’ will be completed. Refer to Section 2, SoA,
for more information.
Subjects who answer ‘Yes’ to any suicidal behaviour or ‘Yes’ to suicidal ideation 
Questions 4 or 5 will be referred to their General Practitioner (GP) or appropriate 

2017N326600_03
CONFIDENTIAL
205184
60
psychiatric care. The medical monitor will be notified. If appropriate, an AE or SAE 
should be reported (see Section 9.1). In addition, the investigator should complete a 
Possible Suicidality Related Adverse Event (PSRAE) form to collect detailed information 
on the circumstances of the reported AEs which, in the investigator’s opinion, are 
possibly suicidality-related. These may include, but are not limited to, an event involving 
suicidal ideation, a preparatory act toward imminent suicidal behaviour, a suicide 
attempt, or a completed suicide.
9.3.7.
Holter Monitoring
Holter monitoring will be performed at screening only. This 24-hour Holter ECG will be 
performed to eliminate subjects with clinically significant cardiac arrhythmias and to 
inform whether possible cardiac rhythm abnormalities potentially observed during 
continuous cardiac telemetry monitoring or 12-lead ECG are different from baseline. If 
necessary, additional or extended monitoring (e.g., telemetry or Holter) may be 
performed at the investigator or sponsor’s discretion to further characterize any emerging 
safety signals.
9.4.
Pharmacokinetics
9.4.1.
Blood Sample Collection
Blood will be collected into EDTA tubes and processed to plasma for PK analysis of 
GSK2982772 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.  
Blood will be collected into EDTA tubes and processed to plasma for PK analysis of M8 
(GSK3562183) and M9 (GSK2997852). This will be collected at the time points 
indicated in Section 2, SoA Tables. The actual date and time of each blood sample 
collection will be recorded. 
Blood will be collected into EDTA tubes and processed to plasma for
4β-hydroxycholesterol and cholesterol. This will be collected at the time points indicated 
in Section 2, SoA Tables. The actual date and time of each blood sample collection will 
be recorded. 
Details of blood sample collection, processing, storage and shipping procedures are 
provided in the SRM. 
9.4.2.
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 GSK2982772
will be determined in plasma samples, and concentrations of M8 (GSK3562183) and M9 
(GSK2997852) will be determined in select plasma samples, using the currently approved 

2017N326600_03

205184
61
bioanalytical methodology. Raw data will be archived at the bioanalytical site (detailed in 
the SRM).
Once the plasma sample has been analysed for GSK2982772 (or M8 [GSK3562183] and 
M9 [GSK2997852] as indicated above), any remaining plasma sample may be analysed 
for any compound-related material and the results may be reported as part of this study or 
under a separate PTS-IVIVT, 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.
9.4.3.
Plasma Sample for CYP3A4 Enzyme Activity
Plasma derived from select PK blood samples in Part B (as in the SoA Table), will be 
analyzed for 4β-hydroxycholesterol and cholesterol as a potential in vivo marker of 
CYP3A4 enzyme activity. Samples collected pre-treatment and at steady-state will be 
compared to evaluate this potential marker.
Details on CYP3A4 enzyme activity marker plasma sample collection, processing, 
storage and shipping procedures are provided in the SRM.
Baseline and Day 14, post-treatment plasma samples will be analyzed using a validated, 
specific, and sensitive liquid chromatography–mass spectrometry (LC-MS/MS) method
to determine concentrations of 4β-hydroxycholesterol and total cholesterol.  A 
comparison will be made between the ratio of 4β-hydroxycholesterol : cholesterol at 
baseline and on Day 14 to assess potential changes in CYP3A4 enzyme activity 
following GSK2982772 treatment.
Analysis will be performed at a bioanalytical site (to be detailed in the SRM) under the 
control of PTS-IVIVT and Third Party Resource, GlaxoSmithKline.
9.5.
Pharmacodynamics
Pharmacodynamic parameters are not evaluated in this study.
9.6.
Genetics
A blood sample for DNA isolation will be collected from participants who have 
consented to participate in the genetics analysis component of the study. Participation is 
optional. Participants who do not wish to participate in the genetic research may still
participate in the study.
In the event of DNA extraction failure, a replacement genetic blood sample may be 
requested from the participant. Signed informed consent will be required to obtain a 
replacement sample unless it was included in the original consent.
See Appendix 6 for Information regarding genetic research. Details on processes for 
collection and shipment and destruction of these samples can be found in the Study 
Reference Manual.

STATISTICAL CONSIDERATIONS
The objectives of this study are to assess the safety and tolerability of single and repeat 
ascending doses of GSK2982772. No formal hypotheses will be tested.  
An estimation approach will be used to describe PK of GSK2982772, where point 
estimates and corresponding 90% confidence intervals will be constructed.
10.1.
Sample Size Determination
No statistical techniques were used to calculate the sample size, and sample size is based 
on feasibility.
The primary objective of the study is safety, where the number of safety events are of 
interest.  A maximum of 9 subjects will receive each active dose and; therefore, if 0/9 of 
a particular safety event in the GSK2982772 group is observed, the upper limit of the 
exact 95% CI indicates that a true incidence rate of 33.6% could not be ruled out.  
Whereas if 1/9 of the same safety event in the GSK2982772 group is observed, the upper 
limit of the exact 95% CI indicates that a true incidence rate of 48.2% could not be ruled 
out.
Using a Bayesian approach to determine the confidence interval around an observed 
safety event, we would assume a flat Beta (1,1) prior, and if we were to observe one
safety event in 9 then the posterior distribution would be Beta (2, 9), as outlined below:
Bayesian Approach to Determine Confidence in a Safety Event.
Thus, we can be 95% certain that the true probability of the safety event lies between 
0.04 and 0.39.

Pharmacokinetic Parameters
To date the pharmacokinetics of GSK2982772 have been studied up to 120 mg BID. The 
maximum between-subject coefficient of variation (CVb) for AUC(0-τ) and Cmax observed 
in study 200975 was 27.1 and 36.1 respectively. 
Based on these estimates of variability, slightly more conservative for a cross-over study
and a sample size of 9 completers in Cohort 2, it is estimated that the lower and upper 
bounds of the 90% confidence interval for the means of AUC and Cmax will be within 
approximately 17.9% and 24.2% of the point estimate, respectively.
10.2.
Sample Size Sensitivity
A sample size sensitivity analysis has been conducted on the primary endpoint, to 
investigate different safety event rates. If the number of subjects who completed each 
active dose changes, then the true incidence rates of safety events that could not be ruled 
out (as outlined in Section 10.1 Sample Size Determination) would change.  These 
changes are outlined in Table 1:

clinical laboratory values, vital sign measurements and 12-lead ECG 
monitoring.
10.4.2.
PK Analyses
Endpoint
Statistical Analysis Methods
Secondary
PK analyses will be described in the RAP. 
The PK of TID and BID dosing on Day 1 in Part A will be evaluated. In 
Part B the comparisons of interest will be:
The PK profile following the 1st dose of the day following administration 
in the fed state (standard meal on Day 9 and high fat meal on Day 11) or in 
the fasted state (Day 14).  
The pharmacokinetic profile following the 1st dose on Day 14 (fasted) and 
the 1st dose on Day 1 (fasted);  
Pharmacokinetic data will be listed and presented in graphical form and 
will be summarized descriptively. 
Statistical summaries of the PK parameter data will be the responsibility of

Descriptive statistics (n, arithmetic mean, standard deviation, 95% CI, 
minimum, median and maximum,) will be calculated for all 
pharmacokinetic parameters by treatment. In addition, for loge-transformed 
variables geometric mean, 95% confidence interval and %CVb (100 * √ 
(exp(SD2) -1)) will be provided, where the SD is the standard deviation of 
log-transformed data.
10.4.3.
Other Analyses
Descriptive statistics (n, arithmetic mean, standard deviation, 95% CI, minimum, median 
and maximum) of circulating glucuronide metabolite (M8; GSK3562183) and des-methyl 
metabolite will be investigated in healthy subjects after single-day and repeat dosing of 
GSK2982772. 
10.4.4.
Interim Analyses
An interim analysis may be performed during the study on completed cohorts in Part A 
and Part B of the study to aid internal decision making only. There will be no changes to 
the study design or planned number of subjects in future cohorts as a result of the interim 
analysis.
For Parts A and B of the study, interim PK analyses will be performed on plasma 
GSK2982772 concentration-time data generated during the conduct of this study.
The decision to proceed to higher dose strengths will be made by the DEC based on 
assessment of safety, tolerability and pharmacokinetic data at the preceding dose. The 
exception to this will be in Part A where only a safety assessment (not PK) for the 120 
mg TID dose will be performed. To date, the PK of GSK2982772 has been well-
characterised up to 120 mg BID in the FTiH study and the 120 mg TID for Part A 
represents a 50% increase in dose where PK simulations are predictable. This analysis 
can include review of individual subject data, summaries, graphical presentations and/or 
statistical analysis.
The RAP will describe the planned interim analyses in greater detail.
10.5.
Dose Escalation Committee
The decision to proceed to the next dose level of GSK2982772 in each Cohort will be 
made by a DEC consisting of the Principal Investigator (or appropriate designee), 
Medical Monitor, GSK Clinical Investigational lead and/or Study Team Leader, GSK 
Pharmacokineticist, a GSK GCSP representative and GSK Statistician. All GSK 
personnel including the GSK Statistician and the GSK Pharmacokineticist will remain 
unblinded throughout the course of the study.

For Part A, dose escalation decisions will be based on data obtained from 6 or more 
subjects receiving GSK2982772 at the prior dose level. The review of the data set will 
consist at a minimum of: listings of all AEs, clinical laboratory results, flagged vital 
signs, flagged findings during continuous cardiac monitoring (telemetry), ECG and PK 
results derived from 24-hour plasma profiles.
The decision and selection of dose to proceed to Part B, will be made by the DEC based 
on safety, tolerability, and PK data from the same dose levels evaluated in Part A.  
For Part B, dose escalation decisions will be based on data obtained from 6 or more 
subjects receiving GSK2982772 at the prior dose level. The review of the data set will 
consist at a minimum of: listings of all AEs, clinical laboratory results, flagged vital 
signs, flagged findings during continuous cardiac monitoring (telemetry) and ECG 
findings through Day 16 of the previous cohorts(s) in Part B. Also included will be any 
PK results derived through at least Day 7 of the previous cohort(s).

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 assessmentse.g.eg, 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 
leads to the procedure is the AE.

Situations in which an untoward medical occurrence did not occur (social and/or 

2017N326600_03
CONFIDENTIAL
205184
80
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 fulfils any other serious criteria, the event is 
serious. When in doubt as to whether “hospitalization” occurred or was necessary, the AE 
should be considered serious.
Hospitalization for elective treatment of a pre-existing condition that did not worsen from 
baseline is not considered an AE.
d.
Results in persistent disability/incapacity

The term disability means a substantial disruption of a person’s ability to conduct 
normal life functions.

This definition is not intended to include experiences of relatively minor medical 
significance such as uncomplicated headache, nausea, vomiting, diarrhoea, influenza, 
and accidental trauma (e.g., sprained ankle) which may interfere with or prevent 
everyday life functions but do not constitute a substantial disruption.
e.
Is a congenital anomaly/birth defect
f.
Other situations:

Medical or scientific judgment should be exercised in deciding whether SAE 
reporting is appropriate in other situations such as important medical events that may 
not be immediately life-threatening or result in death or hospitalization but may 
jeopardize the participant or may require medical or surgical intervention to prevent 

2017N326600_03
CONFIDENTIAL
205184
81
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.

2017N326600_03
CONFIDENTIAL
205184
82
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.

2017N326600_03
CONFIDENTIAL
205184
83
Reporting of SAE to GSK
SAE Reporting to GSK via Paper CRF

Email transmission of the SAE paper CRF is the preferred method to transmit this 
information to the medical monitor or the SAE coordinator.

In rare circumstances and in the absence of email 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.

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 enrolment.
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 treatment phase and 
until at least 90 days after the last administration of study drug: 

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 and recommend subject or partner use of an 
additional method of contraception with a failure rate of <1% per year as 

2017N326600_03

described in Table 4 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 

In addition, male participants must refrain from donating sperm for duration of 
study and for 90 days after study completion or from last dose
Female participants
Female participants of childbearing potential are eligible to participate if they agree to 
use a highly effective method of contraception consistently and correctly as described in 
Table 4 for a minimum of 28 days prior to the first dose of study drug and until at least 30 
days after the last administration of study drug. For female particpants using a hormonal 
method of contraception, partner use of male condoms is also required during the 
treatment period and until at least 28 days after the last administration of study drug.

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 

2017N326600_03

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 the use of a male condom should be utilized during the treatment period 
and for at least 30 days after the last dose of study treatment.
Pregnancy Testing

WOCBP should only be included after a confirmed menstrual period and a negative 
highly sensitive serum pregnancy test 

Additional pregnancy testing at admission to each study period and at the follow-up 
visit.

Pregnancy testing will be performed whenever a menstrual cycle is missed or when 
pregnancy is otherwise suspected.

Pregnancy testing, with a sensitivity of 25 mIU/mL will be performed using the test 
kit approved by the sponsor and in accordance with instructions provided in its 
package insert.
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.

Female Participants who become pregnant

Investigator will collect pregnancy information on any female participant, who 
becomes pregnant while participating in this study. 

Information will be recorded on the appropriate form and submitted to GSK within 
24 hours of learning of a participant's pregnancy. 

Participant will be followed to determine the outcome of the pregnancy. The 
investigator will collect follow up information on participant and neonate, which will 
be forwarded to GSK Generally, follow-up will not be required for longer than 6 to 8 
weeks beyond the estimated delivery date.  

Any termination of pregnancy will be reported, regardless of fetal status (presence or 
absence of anomalies) or indication for procedure. 

While pregnancy itself is not considered to be an AE or SAE, any pregnancy 
complication or elective termination of a pregnancy will be reported as an AE or 
SAE. 

A spontaneous abortion is always considered to be an SAE and will be reported as 
such.  

Any SAE occurring as a result of a post-study pregnancy which is considered 
reasonably related to the study treatment by the investigator, will be reported to GSK
as described in Appendix 4. While the investigator is not obligated to actively seek 
this information in former study participants, he or she may learn of an SAE through 
spontaneous reporting. 
Any female participant who becomes pregnant while participating will discontinue study 
treatment.

Appendix 6: Genetics
USE/ANALYSIS OF DNA

Genetic variation may impact a participant’s response to therapy, susceptibility, 
severity and progression of disease. Variable response to therapy may be due to 
genetic determinants that impact drug absorption, distribution, metabolism, and 
excretion; mechanism of action of the drug; disease etiology; and/or molecular 
subtype of the disease being treated. Therefore, where local regulations and IRB/IEC 
allow, a blood sample will be collected for DNA analysis.

DNA samples will be used for research related to GSK2982772 or immuno-
inflammatory and related diseases. They may also be used to develop tests/assays 
including diagnostic tests) related to GSK2982772 (or study treatments of this drug 
class) and immuno-inflammatory diseases. Genetic research may consist of the 
analysis of one or more candidate genes or the analysis of genetic markers 
throughout the genome [or analysis of the entire genome] (as appropriate)

DNA samples will be analyzed for UDP-glucuronosyltransferase 1-9 family, 
polypeptide A cluster enzyme that is encoded by the UGT1A9 gene complex.  
Additonal analyses may be conducted if it is hypothesized that this may help further 
understand the clinical data. 

The samples may be analyzed as part of a multi-study assessment of genetic factors 
involved in the response to GSK2982772 or study treatments of this class. The 
results of genetic analyses may be reported in the clinical study report or in a 
separate study summary.

The sponsor will store the DNA samples in a secure storage space with adequate 
measures to protect confidentiality. 

The samples will be retained while research on GSK2982772 (or study treatments of 
this class) continues but no longer than 15 years after the last subject last visit or 
other period as per local requirements.

Appendix 9: Protocol Amendment History
The Protocol Amendment Summary of Changes Table for the current amendment is 
located directly before the Table of Contents (TOC).
Amendment 01 (07-Dec-2017)
Overall Rationale for the Amendment: Clarification of the allowed contraception 
methods for female participants of child bearing potential and male participants with 
female partners of child bearing potential. Pharmacogenetic sampling has been 
incorporated into the protocol and glucuronide levels will be assessed in Part A of the 
study, as well as Part B. In addition, further administrative clarifications have been made.

Information
An additional line for ‘Highly 
effective contraceptive method 
(WOCBP only)’ and ‘Contraception 
with male condoms (WOCBP using 
hormonal contraceptive method 
and male subjects with female 
partners of childbearing potential 
only)’ has been added to the SoA 
tables in Section 2.1. and Section 
2.2.
Updated wording for the subject 
selection for the risk of 
Reproductive Toxicity.
Updated wording for Inclusion 
Criteria 4 for Male and Female 
subjects.
Update of the contraception 
guidance wording for women of 
child bearing potential and male 
subjects with female partners of 
child bearing potential.
Female subjects of child-bearing potential 
who use hormonal contraception are 
required to have their sexual partners use a 
male condom from the first dose of study 
drug until the follow-up visit to avoid 
conception until at least 30 days after the 
last administration of drug.
This is being added as a precautionary 
measure for all WOCBP because an AE of 
“breakthrough bleeding” was reported in 
Cohort 1 TP2 of this study in a female 
subject who is on a combination oral 
contraceptive pill. In the FTiH Study 
200975, there was no increase detected in 
an in vivo marker for CYP3A4 enzyme 
activity following repeat dose administration 
up to 120 mg BID.  Measurement of 4β-
hydroxycholesterol is being evaluated in 
this study to determine CYP3A4 enzyme 
activity in repeat dose administration up to 
720 mg/day.  Until data are available the 
added contraception is being required.

A Genetics section has been added 
to the protocol (9.6) and appendix 
(6)
To take a pharmacogenetic sample from 
consenting subjects.
One subject in Cohort 1 (not the subject 
with break through bleeding), had 
consistently high exposure to GSK2982772 
compared to the other subjects (~2-fold 
higher Cmax) for the 120 mg and 240 mg 
TID dose levels. This may be due to a 
UGT1A9 genetic polymorphism, which is 
responsible for the conversion to the 
glucuronide metabolite of GSK2982772.

Laboratory 
Tests
In Part A of the study, 
Haem/Chem/Urinalysis 
assessments can be non-fasted for 
Day -1 and the Follow-Up Visit.
In Part B of the study 
Haem/Chem/Urinalysis 
assessments can be non-fasted for 
Day -1 only.
Additional wording included to Note 
2 in Table 3 - Non-fasted samples 
can be collected on Day -1 (All 
Parts) and at the Follow-Up visit 
(Part A Only).
The fasting lipid panel in Part B was 
separated out in the SoA since it was noted 
to be performed on Day -1 or Day 1.  This 
was moved to Day 1 only since subjects will 
not be fasted on Day -1. The 4β-
hydroxycholesterol will be checked on Day 
1, as a fasted sample.
It is recommended that all other lab time 
points being performed (inclusive of the 
follow-up visit) are to be performed under 
fasted conditions since this is essential to 
assess lipid profiles.
6.2. Exclusion 
Criteria
An additional Exclusion Criteria 
(16) has been added. “The subject 
has participated in a clinical trial 
and has received an investigational 
product within the following time 
period prior to the first dosing day 
in the current study: 30 days, 5 
half-lives or twice the duration of 
the biological effect of the 
investigational product (whichever 
is longer). All subsequent exclusion 
criteria numbers have increased by 
1.

“Randomization can occur on either 
Day -1 or Day 1 in both Parts A and 
B of the study.”
Updated wording to include that 
randomization can take place on 
Day -1 or Day 1 in Section 7.2.
There was a discrepancy in the SoA under 
the procedure “Randomization” in both Part 
A and B on Day -1 and Section 7.2. 
Randomization can take place on either 
Day -1 or Day 1.

removed from this section.
To remove any ambiguity with this 
assessment, the supine position will be the 
only position used to assess vital signs.

(Cohorts 2-4)
A comment has been added to the 
Meals row to state that “Meals will 
be served as per the site schedule 
on Days -1, 16 and 17.”
Clarification of the wording for the meal 
schedule on non-dosing and non PK 
sampling days.
2.2. Time and 
Events Table 
– Part B 
(Cohorts 2-4)
Superscript ‘g’ has been removed 
from the PK blood sampling on Day 
1.
Superscript ‘g’ refers to study assessments 
on Day 14 of the protocol and not Day 1. 
This is a correction of a typographical error.
6.2. Exclusion 
Criteria
Update of the wording in Exclusion 
Criteria 3 to change the definition of 
what constitutes a positive 
tuberculin skin test from <5 mm 
skin induration at 48 to 72 hours to 
>5 mm skin induration at 48 to 72 
hours.
Correction of a typographical error. An 
induration of >5 mm skin induration at 48 to 
72 hours is considered a positive TB test.
7.2. Method 
of Treatment 
Assignment
The Method of Treatment 
Assignment has been updated to 
note that subjects in Cohort 1 will 
be randomized to 1 of 4 treatment 
sequences rather than 1 of 3. The 
additional treatment sequence 
(ABC) has been added. 
Correction of a typographical error. There is 
no change to the randomization ratio, which 
is 3:1.
2.1. Time and 
Events Table

Removal of the 10hr time interval 
post-last dose in note ‘b’ for TID 
dosing. This now reads “TID 
dosing: GSK2982772 or placebo 
will be administered using a 7hr, 
7hr dosing interval.”
Correction of a typographical error. Since 
Part A is a single-day of dosing, this 10hr 
interval has been removed.
2.2. Time and 
Events Table

(Cohorts 2-4)
The Neurological Examination 
originally on Day 4 has been 
moved to Day 3.
Correction of a typographical error. 48hr 
post-first dose assessment would be on 
Day 3.
6.2. Exclusion 
Criteria
Exclusion Criteria 29 has been 
updated to state “Fasting total 
cholesterol” rather than “Total 
fasting cholesterol”.
Correction of typographical error.
