An additional optional Period 
(Period 7) has been added to 
Part B. The clinical protocol 
currently only allows for 
dosing in the morning of 
Day 1 in each period and 
administering a standard 
high-fat breakfast pre-dose. 
The protocol will be updated
to allow dosing in the evening 
and the potential for dosing a 
high-fat breakfast or evening 
meal 30 to 60 minutes 
post-dose (for Part B Period 7 
only).
Based on emerging data from Part B, the 
sponsor (GSK) would like the opportunity 
to investigate whether the 
between-subject variability in absorption 
time following administration of 480 mg 
tablet with a standard high-fat breakfast 
(administered in previous periods) can be 
reduced by changing feeding regimen or 
time of administration in an additional 
optional period (Period 7) to Part B of the 
study. This additional period will allow for 
the possibility of a delayed breakfast or 
evening meal at 30 or 60 minutes 
post-dose, morning or evening dosing 
and/or administration after a standard or 
high-fat breakfast or evening meal.

SYNOPSIS
Protocol Title: A two part, non-randomised, open label study designed to assess the 
pharmacokinetic profile of modified release prototype coated tablet formulations of 
GSK2982772 relative to an immediate release reference tablet formulation at a fixed 
strength (Part A) and the pharmacokinetic profile of alternative tablet strengths of the 
selected modified release prototype coated tablet formulations (Part B, optional) in 
healthy participants.
Short Title: A study to investigate the pharmacokinetics of modified release prototype 
formulations of GSK2982772.
Rationale: Previous clinical studies of immediate release (IR) formulations of 
GSK2982772 resulted in a high peak:trough ratio of GSK2982772. Additionally, the 
short half-life for GSK2982772 (~2 to 3 hours) necessitates twice daily (BID) or three 
times daily (TID) dosing of an IR formulation.  As a result, modified release (MR) 
formulations using a polymer matrix approach with minitablets in capsule and MR tablet 
formulations were investigated. The emerging pharmacokinetic (PK) data of the MR 
formulations investigated to date have demonstrated that a once daily (QD) PK profile 
can be achieved in the fasted state but the polymer matrix formulation is susceptible to 
food effects when administered with a high-fat breakfast. The purpose of this study is to 
evaluate MR prototype coated tablet formulations. The MR coated tablet formulation 
uses a combination of a controlled-release polymer matrix and controlled-release coating 
to achieve a modified-release of the drug. The MR tablet coating used in Part A and the 
initial periods of Part B will have an aperture drilled into the enteric coating of either side
of the tablet.  This allows some drug release to commence in the stomach whilst 
providing a controlled release throughout the GI tract.  This MR tablet coating has been 
used in other formulations (e.g. Lamictal XR) and in vivo has shown robustness against 
food effects. The hypromellose (HPMC) polymer has been shown to be effective in 
achieving a controlled delay to the drug release rate and thus lowering the maximum 
observed concentration (Cmax) and increasing the concentration at 24 hours post-dose
(C24h) of the product.  However, it is believed that the digestive mechanical action that 
the dosage form is exposed to in the fed stomach, and/or the longer stomach retention 
time when dosed in the fasted state, causes an increase in the rate of drug release.  
Application of an enteric coating with apertures will control the release rate when in the 
stomach.  In Part B only, a new IMP will be manufactured to allow comparison of the 
tablet coating either with apertures (i.e., drilled) or without apertures (i.e., full 
coat/non-drilled).  
Part A of the study is an adaptive crossover study that will optimise the MR prototype 
coated tablet formulation to provide a formulation suitable for QD dosing and has no 
clinically significant food effect.  The MR prototype coated tablet formulations have a 
matrix core containing hypromellose polymers.  The MR prototype coated tablet 
formulations will be optimised within a one-dimensional design space where release rate 
from the tablet will be adjusted by varying the polymer ratio in the tablet core.  The 
polymers will be hypromellose 2208 K3LV (polymer 1) and/or K100LV (polymer 2) 
and/or K4M (polymer 3).  The dose will be fixed at 240 mg, and the in vitro release rate 
will be targeted such that the tablet core of GSK2982772 MR prototype coated tablet

10
formulation MR1 will have a dissolution profile that is similar to the release rate of the 
slowest release MR minitab formulation from Study 205017 (approximately 80% in vitro 
release at 12 hours).  GSK2982772 MR prototype coated tablet formulation MR2 will be 
designed such that the in vitro dissolution is slower than that of MR1, and will be the 
slowest available within the design space.  If neither MR1 nor MR2 provide an optimal 
profile, further MR prototype coated tablet formulations will be investigated.  The impact 
of food on the PK of GSK2982772 will also be evaluated for the selected formulation(s).  
After completion of Periods 3, 4 and 5, interim analyses will be conducted to determine 
the formulation and prandial status to be investigated in the next period.  After 
completion of Part A, an interim analysis will be conducted to identify the MR prototype 
coated tablet formulation(s) for progression into Part B.  If none of the MR prototype 
coated tablet formulations are suitable, then Part B of the study may not be conducted or 
Part B may be used to continue to optimise the formulation, which may include varying 
the tablet coating either with apertures (i.e., drilled) or without apertures (i.e., full 
coat/non-drilled) by the manufacture of a new IMP.
Optional Part B will assess the pharmacokinetics of alternative tablet strengths (120 mg 
and 480 mg, or alternative strengths) as allowed by the design space or tablets with 
apertures (i.e., drilled) or without apertures (i.e., full coat/non-drilled) or multiple dosing 
units of the optimum MR formulation selected from Part A.  If the in-vivo profile of 
either or both the 120 mg or 240 mg tablets (or alternative strengths) differs from the 
optimal profile with the 240 mg, the ratio of the polymers K3LV, K100LV and/or K4M 
may be adjusted within each of the alternative strengths. In order to assess the effect of 
the aperture on the in vivo performance of the formulation, a fully coated tablet (i.e.,
without apertures) may be assessed in Part B, Period 3 onwards. If fully coated tablet(s) 
are dosed, the core composition will match a previously dosed formulation to allow a 
valid comparison. Prior to initiation of Part B, a substantial amendment to the 
investigational medicinal product dossier (IMPD), will be submitted to the Medicines and 
Healthcare products Regulatory Agency (MHRA) for approval, to include updated 
information on the selected GSK2982772 MR prototype coated tablet formulations at 
alternative strengths.

Overall Design:
This is an open label, non-randomised single centre, two part, single dose study in 
healthy male and female participants to assess MR prototype coated tablet formulations
of GSK2982772.  The impact of food (high-fat breakfast) on the rate and extent of 
absorption will be evaluated for suitable MR prototype coated tablet formulations, and an 
assessment of alternative tablet strengths, dosing of multiple dose units and 
presence/absence of apertures in the tablet may also be performed. An assessment of a 
standard or high-fat breakfast/evening meal or study drug administration 30 or 
60 minutes before a standard or high-fat (Part B, Period 7 only) breakfast or evening meal 
may also be included. The single dose may be given in the morning or evening (Part B,
Period 7 only).
Part A of the study is a non-randomised up to 6 period, 6-way fixed sequence design in 
which up to 4 MR prototype coated tablet formulations may be evaluated following 
single dose administration in the fasted state (240 mg).  Periods 1, 2 and 3 will evaluate
MR1 (similar in vitro dissolution to the slowest minitab MR formulation from study 
205017), IR tablet (240 mg) and MR2 (slower in vitro dissolution than MR1) 
respectively. Periods 4, 5 and 6 will be flexible and the dosing regimen will be dependent 
on the outcome of Periods 1 to 3.  In Periods 4 to 6, there will be the option to optimise 
the MR release duration and evaluate the impact of a high-fat meal on one or more

already studied MR formulations. In addition, the impact of food (standard breakfast or 
administration 30 or 60 minutes before a standard breakfast) on selected MR prototype 
coated tablet formulations may also be evaluated in Period 5 or 6, as applicable.  There 
will also be the option to cancel Periods 5 and 6 if an optimal formulation is determined 
in Periods 1 or 3 which shows no clinically significant food effect with a high-fat meal in 
Period 4.  There will be interim decisions after Periods 3, 4 and 5, where appropriate, to 
determine the formulation and prandial status to be investigated in the next period.  
Following the final period of Part A, there will be an interim review to determine whether 
to proceed with optional Part B, and if so, the formulations and tablet strengths to be 
investigated in Part B.  
Optional Part B of the study is an open-label, non-randomised up to 7-period fixed 
sequence study design to evaluate the selected MR prototype coated formulation(s) at 
different tablet strengths or as multiple unit doses and with or without apertures in the
tablet coatings.  Up to 4 different MR prototype coated tablet formulations may be 
selected for investigation in Part B.  These will be selected from Part A and ongoing 
interim reviews in Part B; the selected formulations may be adjusted during interim 
reviews during Part B.  The tablet strengths and number of dosing units selected in Part B 
will be based on the exposure of GSK2982772 achieved in an ongoing high dose 
pharmacokinetic study in which doses of the IR tablet up to 240 mg TID are being 
administered, and the bioavailability of the selected MR prototype coated tablet 
formulations relative to the IR tablet (from Part A).  Up to 4 different dose levels (as 
different tablet strengths or multiple unit doses) may be administered in Part B.  The 
proposed dose levels are 120 mg, 480 mg, 960 mg and 1200 mg but these may be 
adjusted following review of the data from Part A or following the interim reviews during 
Part B, as appropriate.  In Part B, administration of the MR prototype coated tablet 
formulations will either be in the fed or fasted state, or administered 30 or 60 minutes
before a standard or high-fat (Period 7 only) breakfast/evening meal (Period 7 only), 
which will be based on emerging PK data.  There will be an interim review following 
each of Periods 1 to 5 of Part B to select the dose level, formulation and prandial status, 
as appropriate, for each subsequent period. An interim data review after Part B Period 6 
will determine if optional Period 7 is required and the dose level, dosing time (morning or 
evening), formulation and prandial status for that period.

Number of Participants:
It is planned to enrol up to 16 participants into each part of the study to allow for 
sufficient data in at least 12 evaluable participants. For Part A, an evaluable participant
will have received the IR tablet formulation (reference) and at least one of the MR 
formulations and will have completed the planned safety and PK assessments up to 
24 hours after dosing.  For the food effect assessment, an evaluable subject will have 
received the chosen MR formulation in the fasted state and the relevant prandial state and 
will have completed the planned safety and PK assessments up to 48 hours after dosing.  
For Part B, an evaluable participant will have completed the planned safety and PK 
assessments up to 48 hours after dosing with at least one MR prototype coated tablet 
formulation.

In Part A, each participant will be enrolled in the study for approximately 10 to 12 weeks, 
dependent on screening and washout duration between periods.  Participation will include 
a screening evaluation within 28 days of study treatment administration and up to 
6 separate inpatient periods.  Subjects will be admitted to the clinic in the morning of the 
day before dosing (i.e., Day -1) of each inpatient period.  Each inpatient period for the 
MR regimens (Periods 1 and 3 to 6) will consist of 4 days and 3 nights, and the inpatient 
period for the IR tablet (Period 2) will consist of 3 days and 2 nights.  There will be a 
minimum washout of 7 days between doses, and a follow-up visit will occur 7 to 9 days 
after the last study treatment.  Participants will receive a single oral dose of study 
treatment during each inpatient period.
In Part B, each participant will be enrolled in the study for approximately 10 to 14 weeks.  
Participation will include a screening evaluation within 28 days of study treatment 
administration and up to 7 separate periods. Participants will be admitted to the clinic in 
the morning of the day before dosing (i.e., Day -1) of each inpatient period.  Each 
inpatient period will consist of a 4-day, 3-night inpatient period with a minimum of 
7 days washout between doses.  A follow-up visit will occur 7 to 9 days after the last 
study treatment. Participants will receive a single oral dose of study treatment during 
each inpatient period.

SCHEDULE OF ACTIVITIES (SOA)
The schedules of activities for each part are presented in Table 1, and the time points for 
the pharmacokinetic (PK) blood sample collection in each part are presented in Table 2.
The timing and number of planned study assessments, including safety or PK
assessments may be altered during the course of the study based on newly available data 
(e.g., to obtain data closer to the time of peak plasma concentrations) to ensure 
appropriate monitoring. 
Any changes in the timing or addition of time points for any planned study assessments 
as a result of emerging PK data must be documented and approved by the relevant study 
team member and then archived in the sponsor and site study files. The competent 
authority (CA) and ethics committee (EC) will be informed of any safety issues that

15
constitute a substantial amendment and require alteration of the safety monitoring scheme 
or amendment of the informed consent form (ICF). The changes will be approved by the 
CA and the EC before implementation.
There are times where the protocol requires more than one procedure to be completed at 
the same time point. In these instances, the following will apply to post-dose time points:
PK samples should take priority over other procedures scheduled at the same time point. 
As guidance, the preferred order of assessments is:
ECGs

Vital 
Signs

PK blood sampling
(nominal time)

Other assessments e.g.
physical exams, 
Electrocardiograms (ECGs) should be taken prior to vital signs when both measurements 
are scheduled at the same time point. Other assessments, e.g., physical examinations etc, 
will be performed within the required time windows. All safety assessments will be 
timed and performed relative to the start of dosing.

INTRODUCTION
GSK2982772 is a first-in-class, highly selective, receptor-interacting protein-1 (RIP1)
kinase inhibitor being developed for the treatment of inflammatory bowel disease, plaque 
psoriasis (PsO), rheumatoid arthritis (RA) and other disease conditions.
3.1.
Background
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 is a key signalling node which plays an essential role in inflammation and 
cell death in response to signals including tumour necrosis factor (TNF) family cytokines, 
ligands for toll like receptor (TLR)3/TLR4, sensors of viral infection, and interferons 
[Ofengeim, 2013].  Through tight regulation by ubiquitylation, deubiquitylation and 
interaction with its receptors, RIP1 has dual roles as a kinase and a scaffolding protein, 
and serves as an upstream checkpoint for both cell death and survival [Ofengeim, 2013].  
Detailed understanding of RIP1 kinase function has not been fully elucidated, but it is 
known that RIP1 exerts it signalling functions through both its catalytic kinase activity 
and by acting as a scaffolding protein for signalling complexes.  Recent work has 
demonstrated that RIP1 catalytic kinase activity can regulate TNF-mediated necroptosis 
[Ofengeim, 2013] and noncanonical apoptosis [Wang, 2008; Dondelinger, 2013].  In 
addition, the production of certain inflammatory cytokines can be regulated by RIP1 
kinase activity.  In contrast, RIP1’s scaffolding function acts to facilitate other immune 
processes including TNF mediated classical apoptosis and Nuclear factor-kappaB-
signalling [Ofengeim, 2013; Humphries, 2015].  With this, an inhibitor of RIP1 kinase 
activity with GSK2982772 may fill a unique niche in the treatment of inflammatory 
conditions, such as ulcerative colitis, chronic PsO and RA, through multiple mechanisms, 
including inhibition of inflammation-induced cell death (necroptosis and apoptosis) and 
inhibition of the production of certain pro-inflammatory cytokines.
A detailed description of the chemistry, pharmacology, efficacy, and safety of 
GSK2982772 is provided in the Investigator’s Brochure [GlaxoSmithKline Document 
Number 2014N204126_03].
3.2.
Study Rationale
Pharmacokinetic data from the first time in human (FTIH) study for GSK2982772 
(200975) [GlaxoSmithKline Document Number 2014N204126_03 ] showed that the 
half-life of GSK2982772 was short (~2 to 3 hours).  As a result, twice daily (BID) and 
three times daily (TID) dosing regimens are being evaluated in three ongoing proof of 
mechanism studies.  A once daily (QD) formulation would be more convenient from a 
patient perspective and could offer the advantage of providing a flatter GSK2982772 
concentration time profile.  Pharmacokinetic data from a modified release (MR)
formulation study (205017) showed that a QD formulation was feasible; however, the 
MR formulation (minitabs in capsules) was susceptible to a food effect and a MR 
monolithic matrix tablet formulation may be mechanistically susceptible to a food effect 
as well.  This study will evaluate the feasibility of developing an MR prototype coated 
tablet formulation using a combination of a controlled release polymer matrix and

controlled-release coating.  The MR tablet coating used in Part A and the initial periods 
of Part B will have an aperture drilled into the enteric coating of either side of the tablet.  
This allows some drug release to commence in the stomach whilst providing controlled 
release throughout the GI tract.  This MR tablet coating has been used in other 
formulations (e.g. Lamictal XR) and in vivo has shown robustness against food effects. 
The hypromellose (HPMC) polymer has been shown to be effective in achieving a 
controlled delay to the drug release rate and thus lowering maximum observed 
concentration (Cmax) and increasing the concentration at 24 h post-dose (C24h) of the 
product.  However, it is believed that the digestive mechanical action that the dosage 
form is exposed to in the fed stomach, and/or the longer stomach retention time when 
dosed in the fasted state, causes an increase in the rate of drug release. Application of an 
enteric coating with apertures will control the release rate when in the stomach.  The MR 
prototype coated tablet formulations have a matrix core containing hypromellose
polymers.  The MR prototype coated tablet formulations will be optimised within a 
one-dimensional design space where release rate from the tablet will be adjusted by 
varying the polymer ratio in the tablet core. In Part B only, a new IMP will be 
manufactured to allow comparison of the tablet coating either with apertures (i.e., drilled) 
or without apertures (i.e., full coat/non-drilled).  
The Clinical Trial Authorisation application for this study describes a flexible protocol 
design using the concept of formulation design space to allow decision-making in 
response to interim PK observations. The principles of a flexible protocol were discussed 
and agreed with the Medicines and Healthcare products Regulatory Agency (MHRA) at a 
Scientific Advice Meeting between the MHRA and Quotient Sciences (formerly 
Pharmaceutical Profiles).
Based upon the concept of formulation design space, specific Investigational Medicinal 
Products (IMPs) are not detailed within the Investigational Medicinal Product Dossier but 
rather a defined range of formulation inputs and corresponding performance outputs are 
described and justified based on in vitro studies.
3.3.
Benefit/Risk Assessment
As of 10 November 2018, approximately 296 participants have been enrolled in 8 clinical 
studies with GSK2982772. In completed Study 200975, GSK2982772 was administered 
up to 120 mg BID for 14 days (total daily dose 240 mg).  A total of 67 participants
received GSK2982772 and 26 participants received placebo (including crossover) in that 
study, of whom 31 participants received a single dose of GSK2982772.  No safety 
concerns were identified and no SAEs, including deaths, were reported in this study.
In ongoing Phase 1 studies (high dose PK Study [205184] and modified release 
formulation Study [205017]), a total of approximately 47 and 45 participants have been 
randomised to single doses of GSK2982772 up to 720 mg/day and repeat doses up to
300 mg/day for 3 days, respectively.  In this ongoing Phase 1 study 209261, 
approximately 17 healthy subjects have been exposed to GSK2982772 as of 10 Nov 
2018.

In the ongoing GSK2982772 study 205184 (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), a subject 
experienced an asymptomatic non-serious adverse event of elevated ALT [7.5 × upper 
limit of normal (ULN)] and AST (4.5 × ULN) on study Day 15, one day after completing 
a 14 day treatment of GSK2982772 120 mg orally three times a day.  Due to the absence 
of another plausible explanation, the event was considered likely related to study drug 
and was severe in intensity. Bilirubin, prothrombin time, and work-up were all within 
normal limits and both ALT and AST returned to normal within 4 weeks.  Confounders 
included the following:
1. Subject received 1 g dose of paracetamol on study Day 13 for headache.
2. Subject had a history of mild aminotransferase elevation (1.7 and 1.3 × ULN for 
ALT and AST, respectively) in another healthy volunteer study while receiving an 
investigational monoclonal antibody.
3. Subject’s AST slightly increased (1.75 × ULN) during the follow-up period after 
initially declining to normal.  Creatine phosphokinase (CPK) was also elevated at 
that time and this elevation could be associated with physical activity.
The benefit/ risk profile is considered unchanged by this single, reversible and 
monitorable event.
In ongoing Study 205017 (A three-part, non-randomised, open label Phase 1 Study 
205017 assessing the PK of GSK2982772 modified release (MR) formulations relative to 
an immediate release (IR) reference formulation (Part A), the PK of escalating, repeat 
doses of a selected MR prototype (Part B), and the PK of GSK2982772 following 
administration of MR formulation in the fed and fasted state (Part C)), a completed 
suicide was reported 29 days after the subject received a single dose of GSK2982772. 
This subject had a prior undisclosed suicide attempt and the event was determined by the 
Investigator to be unlikely related to study drug. Given the short half-life of 
GSK2982772, there is no temporal relationship to support a causal association.
In the Phase 2a studies in PsO (Study 203167) and RA (Study 203168) and in the 
ongoing Ulcerative Colitis (Study 202152), approximately 107 participants (47 in the 
PsO study, 33 in the RA study) have been randomised/exposed to GSK2982772 60 mg 
BID or 60 mg TID. In Study 203167, there was a death of a 19-year-old male participant 
due to an accidental overdose with recreational drug 3,4-methylenedioxy-
methamphetamine (MDMA) that was not considered drug related by the Principal 
Investigator (PI). 
There is currently limited information available about the relationship of adverse events 
(AEs) to administration of GSK2982772 in human subjects. Therefore, all serious 
adverse events (SAEs) are considered unexpected. Any SAE deemed related to the IMP 
will be reported as a Suspected Unexpected Serious Adverse Reaction (SUSAR), in 
compliance with local health authority safety reporting requirements (see Appendix 7).

There was no maternal or developmental toxicity at doses ≤200 mg/kg/day in rats and no
developmental toxicity was evident at doses up to 300 mg/kg/day in rabbits (area under 
concentration vs time curve [AUC] of 1270 µg.h/mL and Cmax of 153 µg/mL).  Non-
clinical studies show no evidence of genotoxicity or teratogenicity.
The compound must not be administered to pregnant women or nursing mothers. 
Women of childbearing potential must use highly effective methods of contraception 
(<1% failure rate; Appendix 5) for 30 days prior to exposure to GSK2982772 until the 
follow-up visit for the final dosing period (7-9 days after the last dose).

SAE of death via accidental overdose of Ecstasy/MDMA in 
a subject receiving GSK2982772 60 mg BID.  There was 
no evidence reported to suggest that this event was a 
suicide.
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 in the FTiH study was diagnosed with herpes 
zoster 42 days after receiving GSK2982772 80 mg 
(Treatment Period 2).  The blinded investigator considered 
the AE to be potentially drug-related.
One subject from the PsO study experienced an AE of 
herpes zoster on Study Day 9 (GSK2982772 60 mg BID).  
The blinded investigator considered the AE to be of 
moderate severity and not related to study drug.
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.
Subject Monitoring:

Subjects will be monitored for signs of infection.

See Individual Stopping Criteria for atypical or 
opportunistic infections (Section 8.1.3).
Vaccinations
No preclinical data.
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.

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

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 (CV) and 
Respiratory Study in monkeys, a decrease in minute 
volume 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 (minute volume) or respiratory rate were 
observed at doses of 1 or 10 mg/kg/day. See Investigator’s
Brochure for GSK2982772 [GlaxoSmithKline Document 
Number 2014N204126_03].
Clinical data:
In the FTIH study, repeat doses of GSK2982772 were 
administered x 14 days in 36 healthy male volunteers. 
Extensive respiratory monitoring with end-tidal carbon 
dioxide (CO2), oxygen saturation and nocturnal respiratory 
rate monitoring was performed.  No SAEs were reported, 
and no drug-associated respiratory-related AEs were 
identified.
Subject Monitoring:

Subjects should be monitored for standard 
respiratory-related AEs.

Vital signs will be monitored during study visits.
Suicidality
GSK2982772 is considered to be a CNS-active drug based 
upon pre-clinical studies.
Clinical data:
In the FTIH study, there have been some reports of 
lethargy, abnormal dreams, and depressed mood. 
Subject Selection:

Subjects with a current history of suicidal ideation and 
behaviour (SIB) or a history of attempted suicide will 
be excluded from the study.

did not plan to take action on these feelings. The 
investigator kept the subject on study.
In the open-label modified release formulation study 
(205017), a completed suicide was reported 29 days after 
the subject received a single dose of GSK2982772. This 
subject had a prior undisclosed suicide attempt and the 
event was determined by the Investigator to be unlikely 
related to study drug. Given the short half-life of 
GSK2982772, there is no temporal relationship to support 
a causal association.
Subject Monitoring:

Subjects receiving multiple doses should be 
monitored appropriately and observed closely for 
suicidal ideation and behaviour or any other unusual 
changes in behaviour.
Reproductive toxicity
Non-clinical data:
There was no maternal or developmental toxicity at doses 
200 mg/kg/day in rats and no developmental toxicity was 
evident at doses up to 300 mg/kg/day in rabbits (AUC of 
1270 µg.h/mL and Cmax of 153 µg/mL).
When GSK2982772 was given to F0 female rats from 
gestation day (GD) 6 through lactation day (LD) 21, there 
was no maternal toxicity observed up to a dose of 
300 mg/kg/day, the highest dose tested.  There were no 
effects on F1 viability up to 300 mg/kg/day, or F1 growth 
and development up to 100 mg/kg/day.  At 300 mg/kg/day, 
mean pup weight was lower than the control from 
post-natal day (PND) 1 through PND 21.
In female rats, GSK2982772 was given for 15 days prior to 
cohabitation, through cohabitation and on GD 0 to 6.  
There was decreased body weight gain and food

consumption prior to mating at 400 mg/kg/day and during 
gestation at >200 mg/kg/day.  At the dose level of 
400 mg/kg/day, there were effects on reproductive 
performance (decreased mean numbers of corpora lutea, 
implantations and mean live litter size and increased 
post-implantation loss).  The NOAEL for female fertility and 
early embryonic development in rats was considered to be 
200 mg/kg/day.
In male rats, there were no effects on mating, fertility and 
organ weights, and no male-mediated foetal 
developmental toxicity following administration of 10, 60 or 
200 mg/kg/day for 44-45 days.  Therefore, the NOAEL for 
reproductive performance and for male-mediated 
developmental toxicity is 200 mg/kg/day. 
The mutagenic and clastogenic potential of GSK2982772 
has been assessed using in vitro tests in bacteria and 
cultured mammalian cells and also in an in vivo rodent 
bone marrow micronucleus assessment to test for 
induction of structural chromosomal damage and/or 
aneuploidy. Appropriate vehicle and positive controls were 
included in each test. In addition, an assessment of the 
route of synthesis for GSK2982772 has been conducted to 
determine if there are any impurities which are known or 
suspected deoxyribonucleic acid (DNA)-reactive mutagens 
are likely to be present in the final drug substance.
Non-clinical studies show no evidence of genotoxicity or 
teratogenicity.

Potential Risk of Clinical Significance
Summary of Data/Rationale for Risk
Mitigation Strategy
OAT3 substrates 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 a 
perpetrator of a drug interaction with OAT3 substrates.  
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.

2014N204126_03 ].
paracetamol/acetaminophen, hormonal contraception, 
hormone replacement therapy and other treatments 
required for AEs.
Subject Monitoring:

Caution is advised when dosing GSK292772 with 
CYP3A4 NTI substrates, OAT3 substrates or Pgp 
inhibitors.
Study Procedures
Cannulation 
During cannulation, more than one attempt may be needed 
to insert the cannula in a vein of a participant and it is 
possible that bruising and/or inflammation may be 
experienced at the site of cannulation.

A vein assessment will be conducted at screening to 
ensure only volunteers with veins suitable for multiple 
venepuncture and cannulation are enrolled.  
Cannulation and venepuncture will only be performed 
by staff who are trained in these procedures.
Electrocardiograms
Electrocardiogram stickers on the participants' chests and 
limbs may cause some local irritation and may be 
uncomfortable to remove. 

Participants will be closely monitored to ensure any 
local irritation does not persist.

Benefit Assessment
There is no intended direct health benefit to the participants in this study.  The benefit to 
participants include contributing to the process of developing new therapies in an area of 
unmet need.

Overall Benefit:Risk Conclusion
Taking into account the measures taken to minimise risk to healthy participants
participating in this study, the potential risks identified in association with GSK2982772
are justified by the anticipated benefits that may be afforded to patients with 
inflammatory conditions such as ulcerative colitis, PsO and RA.

STUDY DESIGN
5.1.
Overall Design
This is an open label, non-randomised single centre, two part, single dose study in 
healthy male and female participants to assess MR prototype coated tablet formulations 
of GSK2982772.  The impact of food (high-fat breakfast) on the rate and extent of 
absorption will be evaluated for suitable MR prototype coated tablet formulations, and an 
assessment of alternative tablet strengths, dosing of multiple dose units and 
presence/absence of apertures in the tablet may also be performed. An assessment of a 
standard or high-fat breakfast/evening meal or study drug administration 30 or 
60 minutes before a standard or high-fat breakfast or evening meal (Part B, Period 7 only) 
may also be included. The single dose may be given in the morning or evening (Part B, 
Period 7 only).
5.1.1.
Part A
Part A of the study is a non-randomised up to 6 period, 6-way fixed sequence design in 
which up to 4 MR tablet prototype coated formulations may be evaluated following 
single dose administration in the fasted state (240 mg) (Figure 1).  Periods 1, 2 and 3 will 
evaluate MR1 (similar in vitro dissolution to the slowest minitab MR formulation from 
study 205017), IR Tablet (240 mg) and MR2 (slower in vitro dissolution than MR1) 
respectively. Periods 4, 5 and 6 will be flexible and the dosing regimen will be dependent 
on the outcome of Periods 1 to 3.  In Periods 4 to 6, there will be the option to optimise 
the MR release duration and evaluate the impact of a high-fat meal of one or more
already studied MR formulations.  In addition, the impact of food (standard breakfast or 
administration 30 or 60 minutes before a standard breakfast) on selected MR prototype 
coated tablet formulations may also be evaluated in Period 5 or 6, as applicable.  There 
will also be the option to cancel Periods 5 and 6 if an optimal formulation is determined 
in Periods 1 or 3 which shows no clinically significant food effect with a high-fat meal in 
Period 4.  There will be interim decisions after Periods 3, 4 and 5, where appropriate, to 
determine the formulations and prandial status to be investigated in the next period.  
Following the final period of Part A, there will be an interim review to determine whether 
to proceed with optional Part B, and if so, the formulations and tablet strengths to be 
investigated in Part B.  
Each inpatient period for the MR regimens (Periods 1, 3, 4 to 6) will consist of 4 days 
and 3 nights, and the inpatient period for the IR tablet (Period 2) will consist of 3 days 
and 2 nights.  There will be a minimum washout of 7 days between doses, and a 
follow-up visit will occur at 7 to 9 days after the last study treatment.  Participants will 
receive a single oral dose of study treatment during each inpatient period.

Part B
Optional Part B of the study is an open-label, non-randomised up to 7-period fixed 
sequence study design to evaluate the selected MR prototype coated tablet formulation(s)
at different tablet strengths or as multiple unit doses and with or without apertures in the 
tablet coatings (Figure 2).  Up to 4 different MR prototype coated tablet formulations 
may be selected for investigation in Part B.  These will be selected from Part A and 
ongoing interim reviews in Part B; the selected formulations may be adjusted during 
interim reviews in Part B.  The tablet strengths and the number of dosing units selected in 
Part B will be based on the exposure of GSK2982772 achieved in an ongoing high dose 
PK study in which doses of the IR tablet up to 240 mg TID are being administered, and 
the bioavailability of the selected MR prototype coated tablet formulations relative to the 
IR tablet (from Part A).  Up to 4 different dose levels (as different tablet strengths or 
multiple unit doses) may be administered in Part B.  The proposed dose levels are 
120 mg, 480 mg, 960 mg and 1200 mg but these may be adjusted following review of the 
data from Part A or following the interim reviews during Part B, as appropriate.  In 
Part B, administration of the MR prototype coated tablet formulations will either be in the 
fed or fasted state, or administered 30 or 60 minutes before a standard or high-fat 
(Period 7 only) breakfast/evening meal (Period 7 only), which will be based on emerging 
PK data.  There will be an interim review following each of Periods 1 to 5 of Part B to 
select the dose level, formulation and prandial status, as appropriate, for each subsequent 
period. An interim data review after Part B Period 6 will determine if optional Period 7 is 
required and the dose level, dosing time (morning or evening), formulation and prandial 
status for that period.
Participants will be admitted to the clinic in the morning of the day before dosing (i.e.,
Day -1) of each inpatient period.  Each inpatient period will consist of a 4-day, 3-night

Criteria for Interim Decisions
In Part A there will be an interim review following completion of Period 3, Period 4 and 
Period 5, where appropriate, to decide whether to dose a different MR prototype coated 
tablet formulation (created by adjusting the percentage polymer content in the core or the 
polymer ratios) or whether to dose one of the previously dosed formulation in the fed 
state (high-fat breakfast). Once the impact of a high-fat meal on a selected MR has been 
studied, the subsequent periods may be dosed in the fasted or fed state (a high-fat 
breakfast or standard breakfast) or dosing 30 or 60 minutes before a standard breakfast.  
There will also be the option to cancel Periods 5 and 6 if an optimal formulation is 
determined in Periods 1 or 3 which shows no clinically significant food effect with a 
high-fat meal in Period 4.  Following the final period of Part A, there will be an interim
review to determine whether to proceed with optional Part B, and if so, the formulations 
and tablet strengths to be investigated in Part B.  The decision to progress to Part B will 
be based upon identifying a formulation from Part A that has an appropriate exposure 
profile and does not show a clinically significant food effect with 1 or more of the food 
states described above. There will be an interim review following each of Periods 1 to 5 
of Part B to select the dose level, formulation and prandial status, as appropriate, for each 
subsequent period. An interim data review after Part B Period 6 will determine if optional 
Period 7 is required and the dose level, dosing time (morning or evening), formulation 
and prandial status for that period.
The highest dose level may be adjusted based on observed relative bioavailability of the 
MR tablet but will be planned that the mean AUC(0-24) and mean Cmax will not exceed the 
GSK2982772 systemic exposure associated with the single day administration of 240 mg 
IR TID (i.e., mean AUC(0-24) of 45.0 µg.h/mL and mean Cmax of 4.3 µg/mL).  These 
exposures are below those achieved at the monkey and rat no observed adverse effect 
levels in the 13-week toxicology studies.
Interim decisions will only be made after a complete review of all relevant data collected 
from the previous dose group. Data should be available from a minimum of 
12 participants who have completed the planned safety and PK assessments up to 
24 hours after dosing, or 48 hours after dosing for the food effect assessment and for 
Part B; if full data, as described below, are not available for 12 participants, the PI, 
scientific lead and sponsor will take a decision as to whether the data available are 
sufficient to support the formulation selection decision. An evaluable participant must 
also have received the relevant test and reference formulations for the comparisons of 
interest e.g., an MR formulation and the IR reference and/or the selected MR formulation 
in both the fed and fasted states. If data in fewer than 12 participants are used in the 
decision process, replacement participants will not be dosed with previous regimens to 
increase the number of participants in the completed regimen.
The following data will be provided to the sponsor by Quotient Sciences:

AEs, vital signs, ECGs, safety laboratory data and physical examinations.

Plasma concentrations of GSK2982772.

The decision on formulation, tablet strength, dose level, dosing time (Part B Period 7 
only) and prandial state selection or stopping the study will be made by the Quotient 
study team (i.e., PI, scientific lead and pharmacokineticist) and sponsor study team (as a 
minimum the sponsor’s medical monitor, Clinical Pharmacokinetics Modelling and 
Simulation [CPMS] and Global Clinical Safety and Pharmacovigilance [GCSP]). The 
decision will be documented and signed by the PI as per Quotient Sciences current 
standard operating procedure (SOP). Evidence of the decision will be retained in the 
Investigator Site File (ISF) and GlaxoSmithKline (GSK) Trial Master File.
The following decision criteria will be used as a guide to MR formulation selection 
during the study.
Since the aim of the MR development programme in to provide a QD formulation with as 
high as possible Cmin, the decision criteria will be based on this PK parameter.  To avoid 
issues with potential outliers at a single nominal time point (e.g. defining C24h as 
minimum observed concentration [Cmin]), the decision criteria will be based on the 
nominal PK sampling times between 18 and 24 hours.  Other PK parameters may also be 
taken into consideration in the MR formulation selection including, but not limited, to 
bioavailability relative to IR, ratios of Cmax:C18h, Cmax:C20h, Cmax:C22h and Cmax:C24h and 
between subject coefficient of variation (CVb) of C18h, C20h, C22h and C24h.  The duration 
of drug release may also be taken into consideration since shorter drug release durations 
using weaker polymers may be more susceptible to food effect whereas longer release 
duration will be more susceptible to PK variability due to inter- and intra-subject 
differences in gastrointestinal transit time.
Food effect arm/s may be conducted with one or more MR formulations and/or one or 
more fed states.
N.B. The release rate of MR1 is planned to be similar to the slowest release minitab in 
study 205017 (~12h for 80% release) and the release rate of MR2 will be the slowest 
available within the design space.

Decision Criteria for Part 1:  Period 5
If an intermediate release rate (MR3) is evaluated in Period 4, then a 2nd intermediate 
release rate (MR4) between MR3 and either MR1 or MR2 may be evaluated using the 
same criteria as in Period 4.  If the criteria for evaluating an intermediate release rate in 
Period 5 are not met, then either MR1, MR2 or MR3 will be administered with a high-fat 
meal in Period 5.
If a faster release rate than MR1 is evaluated in Period 4, then an even faster release rate 
or an interim release rate between MR3 and MR1 or MR2 may be evaluated based on the 
same criteria as Period 4.  If the criteria for evaluating an even faster release rate on an 
intermediate release rate in Period 5 are not met, then either MR1 or MR3 will be 
administered with a high-fat meal in Period 5.
Decision on which MR Formulation to be used for assessment of High-Fat Meal:  
Periods 4, 5 and/or 6
The MR formulation to be selected for the food effect arm will ideally have the highest 
GSK2982772 concentrations in the majority of timepoints between C18h and C24h along 
with the lowest CVb.
Decision on which MR Formulation to be taken to Part 2
The duration of release for the 120 mg and 480 mg MRX formulations in Periods 1 and 2 
will have a similar release rate duration as the optimal MRX formulation from Part A, 
where optimal is defined in the same way as for the food effect arm (e.g. the highest 
GSK2982772 concentrations in the majority of timepoints between C18h and C24h along 
with the lowest CVb).
Decision of whether to evaluate 480 mg or 120 mg MRYh in Part B
If dose normalised Cmin is 10% different compared to the 240 mg dose normalised Cmin,

then the MR release duration may be adjusted in Period 3 and/or Period 4.
5.2.
Number of Participants
It is planned to enrol up to 16 participants into each part of the study to allow for 
sufficient data in at least 12 evaluable participants.  For Part A, an evaluable participant 
will have received the IR tablet formulation (reference) and at least one of the MR 
formulations and will have completed the planned safety and PK assessments up to 
24 hours after dosing.  For the food effect assessment, an evaluable subject will have
received the chosen MR formulation in the fasted state and the relevant prandial state and 
will have completed the planned safety and PK assessments up to 48 hours after dosing.  
For Part B, an evaluable participant will have completed the planned safety and PK 
assessments up to 48 hours after dosing with at least one MR prototype coated tablet 
formulation.
Participants withdrawn due to an IMP-related AE that is at least moderate in severity or 
termination of the study will not be replaced.  If participants prematurely discontinue the 
study for other reasons, additional replacement participants may be recruited at the 
discretion of the Sponsor in consultation with the investigator.
Up to 4 replacement participants may be enrolled in each part of the study. The 
maximum number of participants that may be dosed in each part of the study is 20. 
Replacement participants enrolled will be dosed with the next planned treatment of the 
withdrawn participant, and they will not receive any treatment that the withdrawn
participant has already received unless required to obtain the minimum number of 
evaluable participants required for interim decisions, and to obtain data in any other 
treatment that is required for a valid comparison. Replacement participants will receive 
the required treatments in the same order as planned for the original participants and the 
minimum washout period will be respected with regard to the timing of dosing.
5.3.
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 i.e., the 
follow-up visit.
The definition of the end of the study is defined as the point at which the sponsor 
determines that any remaining optional groups are not required to meet the objectives of 
the trial i.e., signed dose decision document. If all optional groups are used, completion 
of the last follow-up visit will be considered the end of the study.
5.4.
Scientific Rationale for Study Design
Previous clinical studies of IR formulations of GSK2982772 resulted in a high 
peak:trough ratio of GSK2982772.  Additionally, the short half-life for GSK2982772 
(~2 to 3 hours) necessitates BID or TID dosing of an IR formulation.  As a result, MR 
formulations using a polymer matrix approach with minitablets in capsule and MR tablet 
 
2019N407804_00

209261
43
formulations were investigated.  The emerging PK data of the MR formulations 
investigated to date have demonstrated that a QD PK profile can be achieved in the fasted 
state but the polymer matrix formulation is susceptible to food effects when administered 
with a high-fat breakfast. The purpose of this study is to evaluate MR prototype coated 
tablet formulations.  The MR prototype coated tablet formulation uses a combination of a 
controlled-release polymer matrix and controlled-release coating to achieve a 
modified-release of the drug.  The MR tablet coating used in Part A and the initial 
periods of Part B will have an aperture drilled into the enteric coating of either side of the 
tablet.  This allows some drug release to commence in the stomach whilst providing
controlled release throughout the GI tract.  This MR tablet coating has been used in other 
formulations (e.g. Lamictal XR) and in vivo has shown robustness against food effects.  
The HPMC polymer has been shown to be effective in achieving a controlled delay to the 
drug release rate and thus lowering Cmax and increasing the C24h of the product.  
However, it is believed that the digestive mechanical action that the dosage form is 
exposed to in the fed stomach, and/or the longer stomach retention time when dosed in 
the fasted state, causes an increase in the rate of drug release.  Application of an enteric 
coating with apertures will control the release rate when in the stomach.  In Part B only, a 
new IMP will be manufactured to allow comparison of the tablet coating either with 
apertures (i.e., drilled) or without apertures (i.e., full coat/non-drilled).  
Part A of the study is an adaptive crossover study that will optimise the MR prototype 
coated tablet formulation to provide a formulation suitable for QD dosing and has no 
clinically significant food effect.  The MR prototype coated tablet formulations have a 
matrix core containing hypromellose polymers.  The MR prototype coated tablet 
formulations will be optimised within a one-dimensional design space where release rate 
from the tablet will be adjusted by varying the polymer ratio in the tablet core.  The 
polymers will be hypromellose 2208 K3LV (polymer 1) and/or K100LV (polymer 2) 
and/or K4M (polymer 3).  The dose will be fixed at 240 mg, and the in vitro release rate 
will be targeted such that the tablet core of GSK2982772 MR prototype coated tablet 
formulation MR1 will have a dissolution profile that is similar to the release rate of the 
slowest release MR minitab formulation from Study 205017 (approximately 80% in vitro 
release at 12 hours).  GSK2982772 MR prototype coated tablet formulation MR2 will be 
designed such that the in vitro dissolution is slower than that of MR1, and will be the 
slowest available within the design space.  If neither MR1 nor MR2 provide an optimal 
profile, further MR prototype coated tablet formulations will be investigated.  The impact 
of food on the pharmacokinetics of GSK2982772 will also be evaluated for the selected 
formulation(s).  After completion of Periods 3, 4 and 5, interim analyses will be 
conducted to determine the formulation and prandial status to be investigated in the next 
period.  After completion of Part A, an interim analysis will be conducted to identify MR 
prototype coated tablet formulations for progression into Part B.  If none of the MR 
prototype coated tablet formulations are suitable, then Part B of the study may not be 
conducted or Part B may be used to continue to optimise the MR prototype coated tablet 
formulations, which may include varying the tablet coating either with apertures (i.e. 
drilled) or without apertures (i.e., full coat/non-drilled) by the manufacture of a new IMP. 
Optional Part B will assess the pharmacokinetics of alternative tablet strengths (120 mg 
and 480 mg, or alternative strengths) as allowed by the design space or tablets with 
apertures (i.e., drilled) or without apertures (i.e., full coat/non-drilled) or multiple dosing

44
units of the optimum MR formulation selected from Part A.  If the in-vivo profile of 
either or both the 120 mg or 240 mg tablets (or alternative strengths) differs from the 
optimal profile with the 240 mg, the ratio of the polymers K3LV, K100LV and/or K4M 
may be adjusted within each of the alternative strengths.  In order to assess the effect of 
the aperture on the in vivo performance of the formulation, a fully coated tablet (i.e.,
without apertures) may be assessed in Part B, Period 3 onwards. If fully coated tablet(s) 
are dosed, the core composition will match a previously dosed formulation to allow a 
valid comparison.  To investigate whether the between-subject variability in absorption 
time observed following administration of 480 mg tablet with a high-fat breakfast 
(administered in previous periods) can be reduced; a change to the food regimen or time 
of administration may be explored in Part B, Period 7.  Subjects may be dosed in the 
fasted state or fed state (standard or high-fat breakfast/evening meal) or in the fasted state 
followed by a delayed standard or high-fat breakfast/evening meal, on the morning or 
evening of Day 1.  Prior to initiation of Part B, a substantial amendment to the 
investigational medicinal product dossier (IMPD), will be submitted to the MHRA for 
approval, to include updated information on the selected GSK2982772 MR prototype 
coated tablet formulations at alternative strengths.
As this is a Phase 1 study, the most relevant population is healthy participants which
allows characterisation of safety, tolerability and PK in a homogenous population without 
potential biases from a patient population. The European Medicines Agency (EMA)
recommends including participants aged 18 years and older with normal weight, who are 
non-smokers, without a history of alcohol or drug abuse. The latter criteria are proposed 
to avoid interaction on drug metabolism and to avoid non-compliance. Therefore, this 
study will enrol healthy male and female participants aged between 18 to 65 years of age.
5.5.
Dose Justification
In the blinded high dose PK study (205184) in healthy participants, single doses up to 
720 mg/day appear to be well-tolerated with no safety concerns identified. No SAEs or 
deaths have been reported. Repeat dosing with up to 720 mg/day x 14 days is ongoing.
Single doses are to be used in this study since single doses are generally more sensitive 
than steady-state dosing in assessing rate and extent of release of the drug substance from 
the drug product into the systemic circulation. In addition, GSK 2982772 has time in-
dependent pharmacokinetics as demonstrated with similar single and repeat dose PK 
profiles following 14 days dosing with GSK2992772 Immediate Release (Study 200975) 
and following 3 days dose with minitab MR (Study 205017).  Single doses are also 
required for development of in-vitro / in-vivo correlation which may be developed for the 
DiffCore formulation at a later date”.
In Part A, a dose of 240 mg has been selected as this is expected to be safe and well 
tolerated, and is within the expected dose range that is planned to be taken forward into 
the Phase 2b dose ranging studies.
In Part B, the selection of the doses will be based on the results from Part A.  The highest 
dose will not be predicted to exceed the GSK2982772 systemic exposure associated with 
the single day administration of 240 mg TID (i.e., mean AUC(0-24) of 45.0 µg.h/mL and

mean Cmax of 4.3 µg/mL).  These exposures are below those achieved at the monkey and 
rat no observed adverse effect levels in the 13-week toxicology studies.

Subjects must complete 90% of the meal to be dosed.  De-caffeinated fluids 
will be allowed ad-libitum from 4 hours post-dose.  Participants will be 
provided with a snack at 4 hours post-dose.

During each dosing session, participants will abstain from ingesting caffeine- or 
xanthine-containing products (e.g., coffee, tea, cola drinks, and chocolate) for 
24 hours before admission until after collection of the final PK sample in that period.

Participants will abstain from alcohol for 24 hours before screening. During each 
dosing session, participants will abstain from alcohol from 24 hours before 
admission until after collection of the final PK sample in that period.

Current smokers or users of other tobacco products will not be enrolled in this study.
6.3.2.
Activity

Participants will abstain from strenuous exercise for 72 hours before screening and 
then from 72 hours before admission until discharge from the study. Participants 
may participate in light recreational activities during studies (e.g., watching 
television, reading).
6.4.
Screen Failures
Screen failures are defined as participants who consent to participate in the clinical study 
but are not subsequently entered in the study. A minimal set of screen failure information 
is required to ensure transparent reporting of screen failure participants to meet the 
Consolidated Standards of Reporting Trials (CONSORT) publishing requirements and to 
respond to queries from regulatory authorities. Minimal information includes 
demography, screen failure details, eligibility criteria, and any SAEs.
Individuals who do not meet the criteria for participation in this study (screen failure) 
may be rescreened at the discretion of the investigator if the reasons for the screening 
failure are expected to be temporary. Rescreened participants will be assigned a new 
screening number and will be re-consented.

Dose Modification
This protocol allows some alteration from the currently outlined dosing schedule (see 
Section 5.1 and Section 5.5). The dosing regimens in Part B will be selected based on PK 
and safety data from participants in Part A, and the mean AUC(0-24) and Cmax will not 
exceed a total daily dose equivalent to the systemic exposure for IR 240 mg TID (i.e.,
mean AUC(0-24) of 45.0 µg.h/mL and mean Cmax of 4.3 µg/mL) taking into account the 
bioavailability of MR relative to IR (i.e., if the bioavailability of MR is 50% that of IR, 
the maximum daily dose of MR to be administered would be 1440 mg).
The decision on the dose of GSK2982772 to be administered in Part B will be made by 
the sponsor and investigator based on safety, tolerability, and PK data obtained in at least 
12 participants at the prior dose level, as described in Section 5.1.3.
7.3.
Method of Treatment Assignment
This is an open-label, non-randomised study. A treatment allocation list will take the 
place of the randomisation schedule, which will be developed by the sponsor. 
At screening, a unique Subject Number will be assigned to any subject who has at least 
one screening procedure performed, other than informed consent. The unique Subject 
Number will be used to identify individual subjects during the course of the study, and 
will start with
.
A treatment allocation list will be produced by GSK Clinical Statistics prior to the start of 
the study, using the validated internal software, which will dictate the treatments that 
should be administered to each participant in each period. The master treatment 
allocation list will be sent to the site and retained in the ISF.
Participant numbers will be allocated on the morning of dosing of Period 1 according to 
the code 
to 
 for Part A, and 
 to 
for Part B using the lowest number 
available.  Replacement subjects will be assigned Participant Numbers
 to

Preparation/Handling/Storage/Accountability
1.
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.
2.
Only participants enrolled in the study may receive study treatment and only 
authorised 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 authorised 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).
4.
Further guidance and information for the final disposition of unused study treatment 
are provided in the technical agreement. 

Under normal conditions of handling and administration, study treatment is not 
expected to pose significant safety risks to site staff. 

A Material Safety Data Sheet (MSDS)/equivalent document describing occupational 
hazards and recommended handling precautions either will be provided to the 
investigator, where this is required by local laws, or is available upon request from 
GSK.
7.6.
Treatment Compliance

When participants are dosed at the site, they will receive study treatment directly 
from the investigator or designee, under medical supervision.  The date and time of 
each dose administered in the clinic will be recorded in the source documents.  The 
dose of study treatment and study participant identification will be confirmed at the 
time of dosing by a member of the study site staff other than the person 
administering the study treatment.  Study site personnel will examine each 
participant’s mouth to ensure that the study treatment was ingested.
7.7.
Concomitant Therapy
Any medication or vaccine (including over-the-counter or prescription medicines, 
vitamins, and/or herbal supplements) that the participant is receiving at the time of 
enrolment or receives during the study must be recorded in the source data 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 nonprescription drugs (including 
vitamins and dietary or herbal supplements) within 7 days (or 14 days if the drug is a 
potential enzyme inducer) or 5 half-lives (whichever is longer) before the start of study 
treatment until completion of the follow-up visit, unless, in the opinion of the investigator 
and sponsor, the medication will not interfere with the study. 
Paracetamol/Acetaminophen, at doses of 2 grams/day, is permitted for use any time 
during the study. Use of hormonal contraception and hormone replacement therapy is 
permitted provided use is stable 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 to treat AEs.

DISCONTINUATION CRITERIA
8.1.
Discontinuation of Study Treatment
In rare instances, it may be necessary for a participant to permanently discontinue study 
treatment. See the SoA (Section 2) for data to be collected at the time of treatment 
discontinuation and follow-up and for any further evaluations that need to be completed.
8.1.1.
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:

a participant meets one of the conditions outlined in the algorithm below or

when in the presence of abnormal liver chemistries not meeting protocol-specified 
stopping rules, the investigator believes that study treatment discontinuation is in the 
best interest of the participant.

8.1.1.1.
Study Intervention Restart or Rechallenge after liver stopping criteria 
met
Study intervention restart or rechallenge after liver chemistry stopping criteria are met by 
any participant in this study is not allowed.
8.1.2.
QTc Stopping Criteria
The same QT correction formula must be used for each individual participant to 
determine eligibility for and discontinuation from the study.  This formula may not be 
changed or substituted once the participant has been enrolled.
For example, if a participant is eligible for the protocol based on QTcB, then QTcB must 
be used for discontinuation of this individual participant as well.

Once the QT correction formula has been chosen for a participant’s eligibility, the 
same formula must continue to be used for that participant for all QTc data being 
collected for data analysis.  Safety ECGs and other non-protocol specified ECGs 
are an exception. 

The QTc should be based on averaged QTc values of triplicate ECGs obtained 
over a brief (eg, 5-10 minute) recording period.  
A participant that meets either bulleted criterion based on the average of triplicate ECG 
readings will be withdrawn from study treatment.  

QTc >500 msec

Change from baseline (pre-dose Day 1) of QTc >60 msec
See the SoA (Section 2) for data to be collected at the time of treatment discontinuation 
and follow-up and for any further evaluations that need to be completed.
8.1.3.
Individual Safety Stopping Criteria

If a participant experiences a serious or severe clinically significant AE that in the 
clinical judgement of the Investigator 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 or QTc stopping criteria are met.

The participant experiences any signs of suicidal ideation or behaviour.
8.1.4.
Temporary Discontinuation
If a participant is not dosed when planned in a particular period (eg, in case of 
unexpected personal circumstances or AEs that occur between treatment periods), they 
may be dosed at a later date (if a subject cannot re-attend within 28 days, they should be 
considered withdrawn), provided the following criteria are met:

CONFIDENTIAL
209261
59

The AE has resolved or stabilised.

The AE preventing dosing was not considered related to the IMP.

The participant has not met any individual stopping criteria.

It is considered safe to continue to dose in the opinion of the investigator.
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.  If a participant withdraws 
from the study, he/she may request destruction of any samples taken, and the 
Investigator must document this in the site study records.  The reason for 
withdrawal should be documented in the source data.

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.

The Sponsor’s request, for reasons such as significant protocol deviations or 
participant safety concern (and after discussion with the Investigator).

If a participant is withdrawn from study treatment, this participant is also 
considered to be withdrawn from the study following completion of follow-up 
assessments.

Study is terminated by the Sponsor.

Refer to the SoA (Section 2) for data to be collected at the time of study 
discontinuation and follow-up and for any further evaluations that need to be 
completed.
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:

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 source data.

209261
60

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. 
8.4.
Study Stopping Criteria
The study will be halted, and the risk to other participants evaluated, prior to a decision as 
to whether to terminate the study if any of the following criteria are met: 

A serious adverse reaction (i.e., a serious adverse event considered at least 
possibly related to the IMP administration) in one subject.

Severe non-serious adverse reactions (i.e., severe non-serious adverse events 
considered as, at least possibly related to the IMP administration) in two subjects, 
independent of within or not within the same system organ class.
Relatedness will be determined by the investigator. If the study is halted, a temporary halt 
will be submitted to the MHRA and EC in the form of a substantial amendment. The 
study may be resumed or terminated; however, it will not be resumed until a further 
substantial amendment to resume the study is submitted and approved by MHRA and EC.
8.5.
Study Termination
After the start of protocol activities but prior to the commencement of dosing, the study 
may be terminated by the sponsor and investigator without consultation with the MHRA 
and EC. The end of the trial must be notified to the MHRA and EC immediately and at 
the latest within 15 days after the study is terminated, clearly explaining the reasons. A 
description of follow up measures taken for safety reasons, if applicable, will also be 
provided.
If the study is abandoned prior to commencement of any protocol activities, the PI or 
sponsor must notify the EC and MHRA by letter outlining the reasons for abandonment 
of the trial.
Once exposure to GSK2982772 has begun, the study will be completed as planned unless 
the following criteria are satisfied that require a temporary halt or early termination of the 
study.

The occurrence of serious or severe AE(s), as defined in Appendix 4, if 
considered to be related to the IMP.

New information regarding the safety of the IMP that indicates a change in the 
risk/benefit profile for the compound, such that the risk/benefit is no longer 
acceptable for participants in the study.

Significant violation of Good Clinical Practice (GCP) that compromises the 
ability to achieve the primary study objectives or compromises participant
safety.
If any of the above occurs, the study will be terminated if careful review of the overall 
risk/benefit analysis described in Section 3.3 demonstrates that the assumptions have 
changed and that the overall balance is no longer acceptable. In these circumstances,
 
2019N407804_00

61
termination can only take place with the agreement of the investigator and sponsor. The 
MHRA and EC will be informed of study termination.
If it becomes necessary to consider termination of the study after dosing has begun, 
dosing may be suspended pending discussion between the investigator and sponsor. 
Dosing will be stopped immediately on safety grounds.
The study may be terminated or suspended at the request of the MHRA or EC.
9.
STUDY ASSESSMENTS AND PROCEDURES

Study procedures and their timing are summarised in the SoA (Section 2). 

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
(Section 2), 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 or by 
generic screening (eg, blood count) and obtained before signing of ICF may be 
utilised for screening or baseline purposes provided the procedure met the 
protocol-specified criteria and was performed within the time frame defined in the 
SoA (Section 2).

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 
550 mL in a 70-day period.

Repeat or unscheduled samples may be taken for safety reasons or for technical 
issues with the samples.

A participant will be allowed to leave the premises following completion of 
study-specific procedures at 48 hours post-dose (Part A, Treatment Periods 1, 3, 4, 5, 
6 and Part B, all periods) or 24 hours post-dose (Part A, Treatment Period 2)
providing that:
−
No AEs have been reported during the study visit
−
The participant responds positively when asked “How are you feeling?”
If any of these conditions are not met, then the participant may only be allowed to 
leave the clinical unit with the authorisation of the investigator or appropriately 
qualified delegate.

Efficacy Assessments
Not applicable.
9.2.
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). 
9.2.1.
Time Period and Frequency for Collecting AE and SAE 
Information

All SAEs will be collected from the signing of the ICF until the follow-up visit
at the time points specified in the SoA (Section 2).

All AEs will be collected from the start of treatment until the follow-up visit at 
the time points specified in the SoA (Section 2).

Medical occurrences that begin before the start of study treatment but after 
obtaining informed consent will be recorded on the Medical History/Current 
Medical Conditions section of the source data not the AE section.

All SAEs will be recorded and reported to the sponsor or designee within 
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.
9.2.2.
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. 
9.2.3.
Follow-up of AEs and SAEs
After the initial AE/SAE report, the investigator is required to proactively follow each 
participant at subsequent visits/contacts. All SAEs will be followed until the event is 
resolved, stabilised, otherwise explained, or the participant is lost to follow-up (as 
 
2019N407804_00

defined in Section 8.3). Further information on follow-up procedures is given in 
Appendix 4.
9.2.4.
Regulatory Reporting Requirements for SAEs

Prompt notification by the investigator to the sponsor of a SAE is essential so 
that legal obligations and ethical responsibilities towards the safety of 
participants and the safety of a study treatment under clinical investigation are 
met. 

The sponsor has a legal responsibility to notify both the local regulatory 
authority and other regulatory agencies about the safety of a study treatment 
under clinical investigation. The sponsor will comply with country-specific 
regulatory requirements relating to safety reporting to the regulatory authority, 
Institutional Review Boards (IRB)/Independent Ethics Committees (IEC), and 
investigators.

Investigator safety reports must be prepared for SUSARs according to local 
regulatory requirements and sponsor policy and forwarded to investigators as 
necessary.

An investigator who receives an investigator safety report describing a SAE or 
other specific safety information e.g., summary or listing of SAE) from the 
sponsor will review and then file it along with the Investigator’s Brochure and 
will notify the IRB/IEC, if appropriate according to local requirements.

Further details can be found in Appendix 7.
9.2.5.
Pregnancy

Details of all pregnancies in female participants and, female partners of male 
participants will be collected after the start of study treatment and until the follow-up 
visit at the time points specified in the SoA (Section 2).

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, foetal death, stillbirth, 
congenital anomalies, ectopic pregnancy) are considered SAE.
9.3.
Treatment of Overdose
For this study, any dose of GSK2982772 greater than that intended in this study will be 
considered an overdose.
There is no specific antidote for overdose with GSK2982772.
In the event of an overdose, the investigator should:

Closely monitor the participant for AE/SAE and laboratory abnormalities until study 
treatment can no longer be detected systemically (at least 48 hours following the last 
dose of 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 source.
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.
9.4.
Safety Assessments
Planned time points for all safety assessments are provided in the SoA (Section 2).
9.4.1.
Physical Examinations

A complete physical examination will include, at a minimum, assessments of the 
skin, cardiovascular, respiratory, GI and neurological systems. Height and 
weight will also be measured and recorded.

A brief physical examination will include, at a minimum, assessments of the 
skin, lungs, cardiovascular system, and abdomen (liver and spleen).

Investigators should pay special attention to clinical signs related to previous 
serious illnesses.
9.4.2.
Vital Signs

Vital signs will be measured in a semi-supine position after 5 minutes rest and 
will include temperature, systolic and diastolic blood pressure, heart rate and 
respiratory rate.

The acceptable deviations from the nominal vital signs measurement time points 
are:
−
The pre-dose vital signs measurements will be taken ≤2 hours before 
dosing.
−
Post-dose vital signs measurements will be taken ± 15 minutes from the 
nominal post-dose time points.
−
Discharge vital signs measurements will be taken ± 1 hour from the 
nominal time point.

If a participant shows an abnormal assessment at any stage, repeat 
measurements may be made and the abnormality followed to resolution if 
required. Additional measurements may be taken as deemed necessary by the 
investigator.

Any clinically significant abnormality, including changes from baseline
(pre-dose Day 1), must be reported as an AE.

9.4.3.
Electrocardiograms

Triplicate 12-lead ECGs will be obtained at screening and single 12-lead ECGs 
will be obtained as outlined in the SoA (Section 2) using an ECG machine that 
automatically calculates the heart rate and measures PR, QRS, QT, and QTc 
intervals. If a single ECG shows a QTc increase of ≥60 msec from baseline
(pre-dose Day 1), two further ECGs should be performed over a brief period (eg, 
5 to 10 minutes) and the assessment made on the mean QTc of the triplicate 
ECGs.  Refer to Section 8.1.2 for QTc withdrawal criteria and additional QTc 
readings that may be necessary.

The QTc should be based on averaged QTc values of triplicate ECGs obtained 
over a brief (eg, 5 to 10 minutes) recording period.

The acceptable deviations from the nominal ECG measurement time points are:
−
The pre-dose ECG measurements will be taken ≤2 hours before dosing
−
Post-dose ECG measurements will be taken ± 15 minutes from the 
nominal post-dose time point.
−
Discharge ECG measurements will be taken ± 1 hour from the nominal 
time point.

ECGs are to be measured after participant has been in a semi-supine or supine 
position after approximately 5 minutes rest.

If a participant shows an abnormal assessment at any stage, repeat 
measurements may be made and the abnormality followed to resolution if 
required. Additional measurements may be taken as deemed necessary by the 
investigator.

Any clinically significant abnormality, including changes from baseline
(pre-dose Day 1), will be reported as an AE.
9.4.4.
Clinical Safety Laboratory Assessments

Refer to Appendix 2 for the list of clinical laboratory tests to be performed and 
to the SoA (Section 2) for the timing and frequency. 

Blood samples for scheduled laboratory assessments will be taken following an 
overnight fast.

The acceptable deviations from the nominal blood sampling time points for 
laboratory assessments are:
−
Post-dose blood samples will be taken ± 1 hour from the nominal blood 
sampling time except when the time point coincides with the PK blood 
sampling time. In this situation, the time window for the PK sample applies.

The acceptable deviations from the nominal urine sampling time points for 
urinalysis are:
−
Post-dose urine samples will be taken ± 2 hour from the nominal urine 
sampling time.


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 study database. The laboratory reports must be filed with the 
source documents. Clinically significant abnormal laboratory findings are those 
that 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 or within 7 days after the last dose of study 
treatment should be repeated until the values return to normal or baseline or are 
no longer considered significantly abnormal by the investigator or medical 
monitor. 

If such values do not return to normal/baseline within a period of time judged 
reasonable by the investigator, the etiology should be identified and the sponsor 
notified.

All protocol-required laboratory assessments, as defined in Appendix 2, must be 
conducted in accordance with the laboratory manual and the SoA (Section 2).

If laboratory values from non-protocol specified laboratory assessments 
performed at the institution’s local laboratory require a change in participant 
management or are considered clinically significant by the investigator (eg, SAE 
or AE or dose modification), then the results must be recorded in the source.
9.4.5.
Suicidal Risk Monitoring
GSK2982772 is considered to be a CNS-active drug.  There has been some concern that 
some CNS-active drugs may be associated with an increased risk of suicidal thinking or 
behaviour when given to some patients with disease.  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 for 
suicidal ideation and behaviour or any other unusual changes in behaviour. Study 
medication must be immediately discontinued in all participants who experience signs of 
suicidal ideation or behaviour.
Families and caregivers of patients 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.
9.5.
Pharmacokinetics

Blood samples of approximately 2 mL will be collected for measurement of 
plasma concentrations of GSK2982772 as specified in the SoA (see Section 2).
Instructions for the collection and handling of biological samples will be provided 
by the sponsor. The actual date and time (24-hour clock time) of each sample will 
be recorded.

confidentiality will be maintained. 
Plasma analysis will be performed under the control of Platform Technology & Science 
(PTS), In Vitro/In Vivo Translation (IVIVT) and Third Party Resourcing (TPR), GSK.  
Concentrations of GSK2982772 will be determined in plasma using the current approved 
bioanalytical methodology.  Raw data will be archived at the Bioanalytical site as 
detailed in the SRM or equivalent.
9.6.
Pharmacodynamics
Pharmacodynamic parameters are not evaluated in this study.
9.7.
Genetics

A 6 mL blood sample for DNA isolation will be collected from participants who 
have consented to participate in the genetics analysis component of the study, as 
specified in the SoA (see Section 2). Participation is optional. Participants who do 
not wish to participate in the genetic research may still participate in the study.


STATISTICAL CONSIDERATIONS
10.1.
Hypotheses
No formal hypothesis will be tested. However, point estimates and corresponding 90% 
confidence intervals will be derived for Cmax, AUC(0-24), AUC(0-inf) and C24h.
10.2.
Sample Size Determination
The maximum between-subject coefficient of variation (CVb) for the PK parameters 
observed in Part A of Study 205017 were used for precision estimates; CVb (%) for 
AUC(0-inf), Cmax, C18h, C20h, C22h, and C24h were 48.7%, 58.5%, 68.5%, 68.7%, 65.1%, and 
73.2%, respectively. Therefore, the respective estimates of within subject coefficient of 
variation (CVw [%]) are 30.9%, 36.7%, 42.3%, 42.5%, 40.4%, and 44.9%. Based on 
these estimates of variability and a sample size of 12 completers, it is estimated that the 
lower and upper bounds of the 90% confidence interval (CI) for the geometric mean ratio 
(MR/IR) of AUC and Cmax will be within approximately 24.3% and 29.2% of the point 
estimate, respectively.  Similarly, it is estimated that the lower and upper bounds of the 
90% confidence interval for the geometric mean ratio (MR2/MR1) of C18h, C20h, C22h, and 
C24h will be within approximately 32.3%, 33.9%, 34.1%, and 36.2% of the point estimate, 
respectively. 
Since it is expected that the MR1 tablet formulation vs IR is to reduce Cmax by 80% and 
AUC by 40%, a sample size of 12 ensures that the 90% CI is within the region 
0.459-0.796 for AUC and 0.132-0.310 for Cmax if the observed geometric ratio is 
0.57-0.64 for AUC and 0.17-0.24 for Cmax.  Since it is expected that the MR2 tablet 
formulation will increase C18h, C20h, C22h, and C24h by 28%, 43%, 44%, and 27%, 
respectively vs MR1, a sample size of 12 ensures that the 90% CI is within the region 
0.945-1.746 for C18h, 1.046-1.968 for C20h, 1.051-1.985 for C22h, and 0.910-1.784 for C24h
if the observed geometric mean ratio is 1.25-1.32 for C18h, 1.40-1.47 for C20h, 1.41-1.48
for C22h, and 1.24-1.31 for C24h.
Sample Size Sensitivity
Using estimates of parameter (this can be any PK parameter AUC, Cmax) variability 
observed in Part A of Study 205017, the precision of these estimates calculated as half 
width of a 90% confidence interval for the mean ratio (MR/IR or MR2/MR1) and 
expressed as distance from mean to limits for 10, 12, 14 and 16 participants has been 
calculated (Table 3).

16, it is estimated that the lower and upper bounds of the 90% confidence interval for the 
geometric mean ratio of the PK parameter (eg, AUC, Cmax) will be within approximately 
20.3% of the point estimate.
10.3.
Populations for Analyses

The plasma concentration-time data for each of the regimens, the following PK 
parameters will be determined, as data permit: 

maximum observed plasma concentration (Cmax).

time to Cmax (Tmax).

the elapsed time from dosing at which GSK2982772 was first quantifiable in a 
concentration vs time profile (Tlag).

observed concentration at 24 hours post-dose (C24h).

observed concentration at 8 and 12 hours post-dose (C8h and C12h) for IR only.

area under the plasma concentration vs time curve (AUC(0-t), AUC(0-24) and 
AUC(0-inf)).  

the percentage of AUC extrapolated beyond the last measured time point 
(AUC%extrap).

terminal half-life (t1/2).

relative bioavailability (Frelformulation) of test formulations (under fed or fasted 
conditions) vs reference formulation based on AUC(0-24) and AUC(0-inf) (or AUC(0-t) if 
AUC(0-inf) can’t be derived) and Cmax.

relative bioavailability (FrelFE) of fed (high-fat breakfast or high-fat evening meal, 
standard breakfast or standard evening meal or delayed meal (30 or 60 minutes) vs
fasted based on AUC and Cmax.

relative bioavailability (Frel(time effect) of evening dosing vs morning dosing based 
on AUC and Cmax)

relative bioavailability (FrelMRFormulation) of MR prototype coated tablet formulations 
relative to each other, as appropriate, based on AUC and Cmax (optional Part B only) 

Cmax/Dose and AUC/Dose (optional Part B only) 
Descriptive statistics (n, arithmetic mean, standard deviation [SD], 95% CI, minimum, 
median and maximum) will be calculated by treatment for all PK concentrations over 
time and for the derived PK parameters. In addition, for loge-transformed PK parameter 
variables geometric mean, 95% CI and %CVb (100 * √ (exp(SD2) -1)) will be provided, 
where the SD is the standard deviation of log-transformed data.
Endpoint
Statistical Analysis Methods
Primary
The primary PK endpoints to compare MR formulations with IR formulations will be 
summarised descriptively. Ratios of AUC(0-inf), AUC(0-24), (AUC(0-t), if AUC(0-inf) cannot 
be derived), Cmax, C24h for MR formulation to IR formulation will be computed with 
90% CI.
Primary
The primary endpoints for food effect will be summarised descriptively. In addition, 
log-transformed AUC(0-inf) (AUC(0-t), if AUC(0-inf) cannot be derived), C24h, and Cmax will 
be analysed using a mixed effects model with regimen as a fixed effect and subject 
within sequence as a random effect.  Point estimates and corresponding 90% CI will

be computed for the differences in GSK2982772 MR formulation taken in the fed 
state (test) vs in the fasted state (reference) using the residual error from the model 
(MSE). The point and interval estimates on the log-scale will then be exponentially 
back transformed to give estimates of the ratios of geometric means and 90% CI.
Within-subject coefficients of variation for AUC(0-inf)and Cmax will be calculated based 
on the loge-Normal distribution: CVw (%) = sqrt[exp(mse) - 1] x 100, where MSE is 
the residual error from the model.
Statistical analysis of the PK endpoint Tmax of GSK2982772 MR formulation 
administered under both fed and fasted conditions will be separately analysed non-
parametrically [Hauschke, 1990]. The point estimates for the medians for each 
treatment, the median difference and 90% CI for the median difference will be 
calculated for the contrast (test-reference).
Secondary
The secondary PK endpoints for the selected MR formulations at different tablet 
strengths and multiple dose units will be summarised descriptively. 
For Part B, plots of dose vs dose normalised AUC(0-24), C24h and Cmax will be 
generated to determine if there are any dose dependent changes in the absorption of 
GSK2982772 following administration of different tablet strengths and multiple dose 
units of the selected MR formulation(s).
For Part B, dose proportionality will be assessed by visual inspection of dose 
normalised AUC(0-24), AUC(0-inf) [or if not available AUC(0-t)] and Cmax values versus 
dose. Analysis of these loge-transformed parameters may be carried out, using the 
power model.
For Part B Period 7, the relative bioavailability of time effect (Frel(time effect)) will be 
assessed by comparing AUC(0-inf), AUC(0-t), Cmax, Tmax, between evening dosing (test) 
versus morning dosing in the same prandial state (reference).
The Reporting and Analysis Plan will describe the planned PK analyses in greater detail.

10.4.3.
Interim Analyses
No formal statistical analyses are planned. However, after Periods 1 to 3, 4 and 5 of 
Part A are complete, the PK data will be analysed which will guide Periods 4, 5 and 6.
Periods 4, 5 and 6 will be flexible and the dosing regimen will be dependent on the 
outcome (safety and PK) of preceding periods.  There will be the option to optimise the 
MR release duration and/or to evaluate the impact of a high-fat meal on the selected MR 
formulation(s). If an optimal formulation is identified in Part A, Part B will proceed.  If 
none of the MR prototype coated tablet formulations are suitable, then Part B of the study 
may not be conducted or Part B may be used to continue to optimise the MR prototype 
coated tablet formulations. This will be based upon identifying a formulation that has an 
appropriate exposure profile that does not show a significant food effect. 
In Part B, there will be an interim review following completion of each of Periods 1 to 5
to determine the dose level, formulation and prandial status, as appropriate, to be used in 
subsequent periods. There will also be an interim review following completion of 
Period 6 to determine if optional Period 7 is required and the dose level, dosing time 
(morning or evening), formulation and prandial status for that period.
See Section 5.1.3 for full details on the criteria for interim decisions.
The Reporting and Analysis Plan will describe the planned interim analyses in greater 
detail.
10.4.4.
Stopping Criteria
After data is available and analysed for Period 1, 2 and 3 in Part A, a decision to stop the 
study could be triggered if:

The PK profile of IR and MR are similar, based on visual judgement of 
concentration-time curves.  Consideration of PK parameters, AUC(0-inf) and Cmax
will assist with this judgement but no formal quantitative no-go will be defined 
due to the exploratory and flexible nature of the study.

Additional tests may be performed at any time during the study as determined 
necessary by the investigator or required by local regulations.

All laboratory tests with values that are considered clinically significantly 
abnormal during participation in the study should be repeated until the values 
return to normal or baseline.  If such values do not return to normal within a 
period judged reasonable by the Investigator, the etiology should be identified 
and the sponsor notified.

If the participant information sheet (PIS) and ICF are updated as a result of an 
amendment, the new versions will be used to re-consent currently enrolled participants
and must be provided to additional participants prior to their entry into the study.
Protocol Deviations
The study must be conducted in accordance with the Clinical Protocol. Should a protocol 
deviation occur, it must be promptly assessed in order to decide whether any of these 
non-compliances should be reported to the MHRA as a serious breach of GCP and the 
Clinical Protocol.
Protocol waivers are not acceptable.
Deviations from the protocol will be recorded in the source data as noted by the clinical 
staff. If necessary, the sponsor will be informed of the deviation.
Any protocol deviations assessed as major will be discussed with the sponsor in order to 
determine if the withdrawal criteria stated in Section 8 have been met.
Financial Disclosure

Appendix 4: Adverse Events: Definitions and Procedures for 
Recording, Evaluating, Follow-up, and Reporting to GSK
Definition of AE
AE Definition

An AE is any untoward medical occurrence in a clinical study participant, temporally 
associated with the use of a study treatment, whether or not considered related to the 
study treatment.

NOTE: An AE can therefore be any unfavorable and unintended sign (including an 
abnormal laboratory finding), symptom, or disease (new or exacerbated) temporally 
associated with the use of a study treatment.
Events Meeting the AE Definition 

Any abnormal laboratory test results (hematology, clinical chemistry, or urinalysis) 
or other safety assessments (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 (ie, 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 (eg, endoscopy, appendectomy): the condition that 
leads to the procedure is the AE.
 
2019N407804_00

2018N367092_04
CONFIDENTIAL
209261
85

Situations in which an untoward medical occurrence did not occur (social and/or 
convenience admission to a hospital).

Anticipated day-to-day fluctuations of pre-existing disease(s) or condition(s) present 
or detected at the start of the study that do not worsen.
Definition of SAE
If an event is not an AE per definition above, then it cannot be an SAE even if serious 
conditions are met (eg, 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 (eg, sprained ankle) which may interfere with or prevent 
everyday life functions but do not constitute a substantial disruption.
e.
Is a congenital anomaly/birth defect
f.
Other situations:

Medical or scientific judgment should be exercised in deciding whether SAE 
reporting is appropriate in other situations such as important medical events that may 
 
2019N407804_00

2018N367092_04
CONFIDENTIAL
209261
86
not be immediately life-threatening or result in death or hospitalization but may 
jeopardise the participant or may require medical or surgical intervention to prevent 
one of the other outcomes listed in the above definition. These events should usually 
be considered serious.
Examples of such events include invasive or malignant cancers, intensive treatment 
in an emergency room or at home for allergic bronchospasm, blood dyscrasias or 
convulsions that do not result in hospitalization, or development of drug dependency 
or drug abuse.
Definition of an Adverse Drug Reaction (ADR)
An ADR is defined as any untoward medical occurrence that, at any dose:

where a causal relationship with the IMP is at least a reasonable possibility (possibly 
related or related)
Definition of SUSAR
A SUSAR is defined as any untoward medical occurrence that, at any dose:

Is believed to be related to an IMP and is both unexpected (ie the nature or severity is 
not expected from the information provided in the Investigator’s Brochure) and 
serious. SUSARs are subject to expedited reporting to the MHRA, European 
Medicines Agency (EMA), EC (see Appendix 7)
Recording AE and SAE
AE and SAE Recording

When an AE/SAE occurs, it is the responsibility of the investigator to review all 
documentation (eg, hospital progress notes, laboratory, and diagnostics reports) 
related to the event.

The investigator will then record all relevant AE/SAE information in the source (ie 
the date and time of onset, a description of the AE, severity, duration, actions taken, 
outcome and an investigator’s current opinion on the relationship between the study 
treatment and the event).

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 source.

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.
 
2019N407804_00

2018N367092_04
CONFIDENTIAL
209261
87

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; intervention may be needed.

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 utilised 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 
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 
 
2019N407804_00

2018N367092_04
CONFIDENTIAL
209261
88
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 recognised 
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 source data.

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 Electronic Data Collection Tool

The primary mechanism for reporting SAE to GSK will be the electronic data 
collection tool.

If the electronic system is unavailable for more than 24 hours, then the site will use 
the paper SAE data collection tool (see next section).

The site will enter the SAE data into the electronic system as soon as it becomes 
available.

The investigator or medically-qualified sub-investigator must show evidence within 
the study database (eg, check review box, signature, etc.) of review and verification 
of the relationship of each SAE to IP/study participation (causality) within 72 hours 
of SAE entry into the study database.

After the study is completed at a given site, the electronic data collection tool will be 
taken off-line to prevent the entry of new data or changes to existing data.

If a site receives a report of a new SAE from a study participant or receives updated 
data on a previously reported SAE after the electronic data collection tool has been 
taken off-line, then the site can report this information on a paper SAE form (see 
next section) or to the medical monitor by telephone.

Contacts for SAE reporting can be found in the Communication Plan.

89
SAE Reporting to GSK via Paper CRF

Facsimile transmission of the SAE paper CRF is the preferred method to transmit 
this information to the medical monitor.

In rare circumstances and in the absence of facsimile equipment, notification by 
telephone is acceptable with a copy of the SAE data collection tool sent by overnight 
mail or courier service.

Initial notification via telephone does not replace the need for the investigator to 
complete and sign the SAE CRF pages within the designated reporting time frames.

Contacts for SAE reporting can be found in the Communication Plan.

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)
If fertility is unclear (e.g., amenorrhea in adolescents or athletes) and a menstrual cycle 
cannot be confirmed before first dose of study intervention, additional evaluation should 
be considered.
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
For individuals with permanent infertility due to an alternate medical cause other 
than the above, (e.g., mullerian agenesis, androgen insensitivity), investigator 
discretion should be applied to determining study entry.
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 (ie
≥40 IU/L) 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-estrogen 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.

Highly Effective Contraceptive Methods

CONTRACEPTIVESa ALLOWED DURING THE STUDY INCLUDE:

Highly Effective Methodsb That Have Low User Dependency Failure rate of <1% per 
year when used consistently and correctly.

Implantable progestogen-only hormone contraception associated with inhibition of 
ovulationc

Intrauterine device (IUD)

Intrauterine hormone-releasing system (IUS)c

Bilateral tubal occlusion

Vasectomized partner

Note: Vasectomized partner is a highly effective contraceptive method provided that 
the partner is the sole sexual partner of the woman of childbearing potential and the 
absence of sperm has been confirmed. If not, an additional highly effective method of
contraception should be used. Spermatogenesis cycle is approximately 90 days.

Highly Effective Methodsb That Are User Dependent Failure rate of <1% per year when 
used consistently and correctly.

Combined (estrogen- and progestogen-containing) hormonal contraception associated with 
inhibition of ovulation
oral
intravaginal
transdermal
injectable

Progestogen-only hormone contraception associated with inhibition of ovulationc
Oral
Injectable

Sexual abstinence

Note: 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 intervention. The reliability of sexual abstinence needs to be evaluated in 
relation to the duration of the study and the preferred and usual lifestyle of the 
participant
a.
Contraceptive use by men or women should be consistent with local regulations regarding the use of 
contraceptive methods for those participating in clinical studies.
b.
Failure rate of <1% per year when used consistently and correctly. Typical use failure rates differ from those 
when used consistently and correctly.
c.
If locally required, in accordance with Clinical Trial Facilitation Group (CTFG) guidelines, acceptable 
contraceptive methods are limited to those which inhibit ovulation as the primary mode of action.
Note: Periodic abstinence (calendar, sympto-thermal, post-ovulation methods), withdrawal (coitus interruptus), 
spermicides only, and lactational amenorrhoea method (LAM) are not acceptable methods of contraception for this 
study. Male condom and female condom should not be used together (due to risk of failure with friction)

5.8 mIU/mL will be performed and assayed in the certified local laboratory (The 
Doctors Laboratory)  
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 foetal
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 foetal 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 for medical reasons 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 be withdrawn 
from the study

Appendix 7: Safety Reporting to Ethics Committee and 
Regulatory Authorities
Events Requiring Expedited Reporting
SUSARs are subject to expedited reporting to the MHRA, EMA and EC.
In addition to SUSARs, other safety issues may qualify for expedited reporting where 
they might materially alter the current benefit-risk assessment of an IMP or that would be 
sufficient to consider changes in the IMPs administration or in the overall conduct of the 
study, for instance:

an increase in the rate of occurrence or a qualitative change of an expected serious 
adverse reaction, which is judged to be clinically important

SAEs that occur after the participant has completed the clinical study where the 
sponsor considers them to be a SUSAR

new events related to the conduct of the study or the development of the IMPs and 
likely to affect the safety of the participants, such as:
−
an SAE which could be associated with the study procedures and which could 
modify the conduct of the study
−
a major safety finding from a newly completed animal study (such as 
carcinogenicity)
−
any anticipated end or temporary halt of a study for safety reasons and 
conducted with the same IMPs in another country by the same sponsor
Reporting of Suspected Unexpected Serious Adverse Reactions (SUSARs)
It is the responsibility of the sponsor to determine whether a reported SAE fits the 
classification of a SUSAR and to notify the investigator of their decision as soon as 
possible.
Expedited Reporting of Events
It is the responsibility of the sponsor to determine whether an event requires expedited 
reporting and to notify the investigator of their decision as soon as possible.
Where expedited reporting is required, the following procedures should be followed.
Fatal or life-threatening SUSARs
It is the responsibility of the sponsor to report fatal or life-threatening SUSARs to the 
MHRA and EMA as soon as possible, but no later than 7 calendar days after they first 
became aware of the reaction. This responsibility may be delegated to the 
pharmacovigilance provider.
The investigator is required to notify the EC of any SUSAR as soon as possible, but no 
later than 7 calendar days after they first became aware of the reaction.
Any additional relevant information should be sent within 8 days of the report.

Other SUSARs
It is the responsibility of the sponsor to report other SUSARs to the MHRA and EMA as 
soon as possible, but no later than 15 calendar days after they first became aware of the 
reaction. This responsibility may be delegated to the pharmacovigilance provider.
The investigator is required to notify the EC of other SUSARs as soon as possible, but no 
later than 15 calendar days after they first became aware of the reaction.
Urgent Safety Measures
If Quotient Sciences or any of its staff or contractors becomes aware of an actual or 
potential urgent safety issue, then the sponsor must be immediately contacted so that 
appropriate urgent safety measures can be agreed. An urgent safety issue is defined as: 

An immediate hazard to the health or safety of participants enrolled in a clinical study

A serious risk to human health or potentially a serious risk to human health
An urgent safety issue may include issues with an investigational drug or comparators, 
study procedures, inter-current illness (including pandemic infections), concomitant 
medications, concurrent medical conditions or any other issues related to the safe conduct 
of the study or that pose a risk to study participants.
In exceptional circumstances of imminent hazard and in order to safeguard the health or 
safety of individuals, Quotient Sciences may take urgent safety measures before 
informing the sponsor, but the sponsor must be informed immediately after the hazard 
has resolved. 
Quotient Sciences will take responsibility for informing appropriate competent 
authorities, and the EC.
Reporting of Urgent Safety Issues
Quotient Sciences is required to inform the appropriate competent authorities and the EC
within 3 calendar days of the urgent safety issue.
Serious Breaches
It is the responsibility of the sponsor to notify the licensing authority of any serious 
breach, which is likely to affect, to a significant degree, the safety or mental integrity of 
the participants of the study or the scientific value of the study. 
All serious breaches will be notified to the MHRA within 7 days. The reporting will be 
performed by the party who suspects the serious breach.

Appendix 8: 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 hypothesised 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 1 28-AUG-2018
Overall Rationale for the Amendment:
This amendment addresses the Grounds for Non-Acceptance (GNA) received by MHRA 
noting that an Investigator should only have the responsibility of determining causality of 
a SAE or severe clinically significant AE without sponsor consultation.
Section # 
and Name
Description of Change
Brief Rationale
Section 8.1.3
Removal of GSK MM consultation 
for determining causality of a SAE 
or severe clinically significant AE.
The determination of causality for individual 
subject withdrawal should be at the 
responsibility of an Investigator only.
Amendment 2 26 FEB 2019
Overall Rationale for the Amendment
This amendment includes a new investigational medicinal product (IMP), requested by 
the sponsor, in order to compare the type of coating for GSK2982772 Modified Release 
(MR) prototype coated tablets. This substantial amendment will also incorporate protocol 
non-substantial amendments (NSA) 03 to 06, which were implemented after 
Amendment 1 approval date 28 AUG 2018.

Part B
The clinical protocol currently 
only allows variance of the 
polymer content of the tablets 
core. Tablets are currently 
manufactured with an 
aperture on either side of the 
tablet (i.e., drilled). A new IMP 
will be manufactured without 
apertures (i.e., full coat/non-
drilled).
The sponsor would like to compare the 
current modified release tablet, which has 
an aperture drilled into the coating on 
each side of the tablet, with a fully coated 
tablet. The composition of the coat will not 
change between formulations. An 
additional IMP will be manufactured to 
allow comparison of the tablet coating -
without apertures (i.e., full coat/non-
drilled) or with apertures (i.e., drilled).

The IR tablet will be dosed in 
Period 2 (Regimen B) and the 
MR prototype coated tablet 
MR2 will be dosed in Period 3 
(Regimen C). 
The Sponsor requested that the 
immediate release reference tablet is to 
be dosed in Period 2 instead of Period 3. 
There have been some issues with some 
of the supplied modified release tablet 
batches and the Sponsor required time to 
investigate the quality of the product and 
assess if a re-manufacture was required 
before dosing in the clinic.

be administered in Part B, 
Periods 2 to 6. 
Following review of clinical data from 
Part A of this study and data generated as 
part of other studies used for dose 
prediction, the highest dose in Part B 
would require dosing multiple units rather 
than only one tablet of high strength. The 
sponsor would like to have the option to 
dose at a higher strength based on 
emerging data.

Benefit/Risk 
Assessment
Updates made based on 
emerging safety results from

The protocol currently only allows for an 
alternative composition of tablet to be 
dosed in Part B Periods 3 to 5. Following 
review of clinical data from Part B 
Periods 1 and 2, the sponsor would like to 
have the option to dose a formulation
