Conditions: Amyloidosis
Keywords: GSK3039294 GSK2315698 systemic amyloidosis CPHPC dose-escalation
Sponsor: GlaxoSmithKline
Start date: 2016-05-12; Completion date: 2017-05-10
Enrollment: 23 participants; Allocation: NON_RANDOMIZED; Intervention model: PARALLEL

Brief summary:
GSK3039294 has been developed in order to offer an orally available alternative to parenteral CPHPC (GSK2315698 \[metabolite of GSK3039294\]) for plasma serum amyloid P component (SAP) depletion prior to use of anti SAP monoclonal antibody (mAb) in the treatment of systemic amyloidosis. This phase 1 study is intended to study safety, tolerability and pharmacokinetic (PK) profile of GSK3039294 in humans. This study consists of three parts. Part A will evaluate safety and tolerability of single doses of GSK3039294 in healthy subjects, Part B will evaluate safety and tolerability of repeat doses of GSK3039294 in healthy subjects, and Part C will evaluate safety and tolerability of repeat doses of GSK3039294 in subjects with systemic amyloidosis. Part A is a single dose, open label, dose escalation study. Two cohorts of subjects will be enrolled to provide data from 6 subjects per cohort and up to 4 different doses (2 dose levels per cohort) of GSK3039294 will be tested. For Cohorts 1 and 2, each subject may take part in two dosing periods. Part B is repeat dose, open label, dose escalation study. Sufficient number of subjects will be enrolled in Cohort 3a to ensure 6 completers (Cohort 3b will be conducted if required) and GSK3039294 will be administered repeatedly for a total of 21 days. Each subject will take part in a single study period. In Part C a single dose level of GSK3039294 will be tested for 21 days repeat dose, in 12 subjects with systemic amyloidosis. Each subject will take part in a single study period. The total duration for Part A is approximately 8 weeks, Part B is approximately 8-9 weeks, and Part C is approximately 13 weeks.

Detailed description:

Arms: arm 1: Subjects will receive a single dose of GSK3039294 (Dose level 1) on Day 1 and will remain in-house until Day 4. Wash-out will take place from Day 5 to Day 14. Subjects will receive Dose level 2 on Day 15 (Period 2). arm 2: Subjects will receive a single dose of GSK3039294 (Dose level 3) on Day 1 and will remain in-house until Day 4. Wash-out will take place from Day 5 to Day 14. Subjects will receive Dose level 4 on Day 15 (Period 2). arm 3: Subjects will receive repeat dosing of GSK3039294 for a total of 21 days. The dose will be escalated every week throughout the study duration. Subjects will first receive a low dose given once daily. After 7 days, if well tolerated, the total daily dose will be increased and, GSK3039294 will be given, for example, as twice daily dosing for 7 days. At the end of this 7 day period and if previous dosing was well tolerated, the dose will be increased to a maximum daily dose that will not exceed pre-clinical safety exposure limits. On Day 4 and 5 GSK3039294 will be administered under fasted and fed conditions, respectively, to investigate the food effect on the PK. arm 4: Subjects will be enrolled in Cohort 3b only if required for further investigation. Subjects will receive GSK3039294 for 21 consecutive days and more than one dose level or regimen may be investigated, for example on the first 10 days the dose may be administered thrice daily, and on the last 11 days may be administered twice daily. arm 5: Subjects will receive repeat dosing of GSK3039294 at the predicted optimal clinical dose determined from Part B for a total of 21 days.
Interventions: intervention 1: GSK3039294
Intervention descriptions: intervention 1: GSK3039294 will be provided as white, opaque capsules. A single capsule or multiple capsules (20 mg to 200 mg), depending on the dosage required, will be taken orally with water.

Overall Design
This is a three-part, open-label, non-randomised study.

Treatment Arms and Duration
Part A: Single dose escalation in healthy volunteers
Two cohorts (cohorts 1 and 2) of subjects will be enrolled to provide data from 6 subjects 
per cohort and up to 4 different doses (2 dose levels per cohort) of GSK3039294 will be 
tested.
Subjects will be admitted to the unit on Day -1, following the dose on Day 1 subjects will 
remain in-house until Day 4. Wash-out will take place from Day 5 to Day 14.
Providing a review of the data from each dose (safety data: AE, vital signs, ECG and 
laboratory safety test and PK data up to 48 h etc) is favourable, the next dose level will be 
administered. 
Part B: Repeat dose escalation in healthy volunteers
Cohort 3: In a group of healthy volunteers (preferably < 45 years of age) sufficient 
subjects will be enrolled to ensure 6 completers, the study drug will be administered 
repeatedly for a total of 7 days.  The dose will be one that is expected to be well tolerated 
based on the single dose data and not predicted to exceed exposure limits based on single 
dose PK. 
A sentinel subject will be dosed first with repeat GSK3039294 administration for 7 
consecutive days. Subsequent subjects will only be dosed after the sentinel subject has 
successfully completed the full 7 days of dosing without any clinically concerning AEs 
being reported. If the safety data from the sentinel subject is deemed to be equivocal, a
second subject can be dosed individually for 7 days at the discretion of the Investigator in 
consultation with the GSK study team. If the safety data from the second subject is also 
equivocal, at the discretion of the Investigator in consultation with the GSK study team, 
subsequent subjects can also be individually dosed with GSK3039294 for 7 days. 
The food effect exploration in Cohort 3 will only be conducted once the Investigator in 
consultation with the GSK study team is satisfied with the safety profile of repeat dose 
GSK3039294. Following this, the food effect will be conducted on Days 4 and 5, and 
GSK3039294 will be administered under fasted and then under fed conditions
(respectively).
Sufficient subjects will be enrolled to ensure a minimum of 6 subjects complete all study 
procedures, including the food effect exploration.
Providing a review of the data (safety data: AE, vital signs, ECG, telemetry, laboratory 
safety tests and PK) is overall acceptable, Cohort 4a will be initiated. The approving REC 
will be informed of the outcome of this data review.
Cohort 4a: In a group of healthy volunteers sufficient subjects will be enrolled to ensure 6 
completers, the study drug will be administered repeatedly for a total of 21 days.

The dose level for this cohort will be determined by a review of the safety and PK data 
from cohort 3. The dose may be adjusted (up or down) during the 21 day dosing session 
based on preliminary PK collected during dosing and ongoing review of safety. If the 
dose is to be altered, this will be done no later than Day 16 in order to achieve a new 
steady-state at Day 21.
The predicted maximum daily exposure will not exceed pre-clinical safety exposure 
limits.
Cohort 4b(optional, only if required): Based on data from Cohorts 3 and 4a, dose levels 
may be selected for further investigation in a further cohort of healthy volunteers 
(recruitment to ensure 6 completers). For this purpose the compound will be dosed for 21 
consecutive days. The dose level and / or dosing regimen may be altered once during the 
21days providing a review of the data from the starting dose (safety data: AE, vital signs, 
ECG, laboratory safety tests and PK – all obtained once steady state has been achieved) is
favourable. The predicted maximum daily dose administered will not exceed pre-clinical 
safety exposure limits.
Part C: Repeat dose escalation in patients with systemic amyloidosis
A single dose level of GSK3039294 will be tested for 21 days repeat dose, in patients 
with systemic amyloidosis which may include those with cardiac amyloid involvement.
Type and Number of Subjects
In Part A, sufficient healthy volunteers will be enrolled to ensure 6 subjects per cohort 
have completed the in-patient phases.
In Part B, sufficient healthy volunteers will be enrolled to ensure 6 subjects per cohort 
have completed each of the in-patient phases.
In Part A and B of the study, if subjects prematurely discontinue, replacement subjects 
may be enrolled and assigned to the same cohort at the discretion of the Sponsor in 
consultation with the investigator. Replacement subjects do not need to have received the 
first dose for a given cohort to join the study in the second cohort.
In Part C, a minimum of 12 patients with systemic amyloidosis will be enrolled. If 
subjects prematurely discontinue, replacement subjects may be enrolled at the discretion 
of the Sponsor in consultation with the investigator.  
Additional subjects/cohorts may be enrolled to allow for further evaluation of a given 
dose or for evaluation of additional dose levels.

Analysis
There are no formal hypotheses to be tested as part of this study.
Interim analyses
Safety, PK and PD data will be reviewed on an ongoing basis throughout the study by the 
study team and investigator in order to inform dosing decisions for subsequent dosing 
sessions, cohorts and study parts.  
In addition, in all Parts of the study, individual profiles over time will also be presented 
graphically for selected urine and plasma laboratory parameters pertaining to the kidney. 
To inform dosing decisions for subsequent dosing sessions in Part A, individual values of 
Cmax and AUC[0-inf] will be derived by means of non-compartmental analysis.  To 
inform dosing decisions for subsequent study parts, GSK2315698 concentration data and 
plasma SAP levels will be analysed using the PK/PD model that was developed for 
GSK2315698.
Primary and secondary analyses
Safety, PK and PD data will be listed, summarised and presented graphically as 
appropriate. GSK2315698 concentration data and plasma SAP levels will be analysed 
using the PK/PD model that was developed for GSK2315698.
Cohort Safety Reviews: A safety review will be performed on completion of each Cohort 
in Part B, as well as at completion of Cohort 5 in Part C (see Section 4.2.2. & Section 
4.2.3.). Initiation of Cohort 4a will be contingent on the findings of the safety review at 
completion of Cohort 3 (see Section 4.2.2.)
Summary of Cardiac Arrhythmia Adverse Events in Part A of this study
A total of 4 separate arrhythmias in 3 male subjects over 45 year old were reported on 24-
hour Holter after single dose administration of GSK3039294 in Part A. Three episodes of 
supraventricular tachycardia (SVT), all of atrial tachycardia morphology at doses of 
GSK3039294 at 600mg and 1200mg, and one episode of a single 5-beat accelerated 
idioventricular rhythm (AIVR) at 600mg GSK3039294, were reported in these 3 separate 
subjects. Each of the events was of short duration, completely asymptomatic, and was not 
associated with hemodynamic instability. 
No prolongation of the QTcF interval was observed in any subject after administration of 
200mg, 600mg, or 1200mg of GSK3039294 in Part A.
Both SVTs and ventricular salvos of short duration are known to occur in healthy 
volunteer subjects and can be considered to be within the normal (non-pathological) 
variation of ECG parameters. In this regard, SVTs have been reported to arise in 13.9% 
of healthy volunteer subjects over 45 years of age compared to an incidence of 1.1% in 
healthy volunteer subjects 45 years or less in FIH studies (Hingorani et al, 2016). In Part 
A, none of the three affected subjects had plasma levels of GSK3039294 detectable 
approximate to the time at which each cardiac arrhythmia occurred. Moreover, the timing

of each of the four arrhythmic events after dosing with GSK3039294 was not associated 
with the Tmax of CPHPC including one subject whom had no detectable plasma CPHPC 
present at approximately the time of the first of their two arrhythmic events.
Therefore, at this time, given that there were also no arrhythmogenic liabilities identified 
for GSK3039294 in preclinical toxicological studies, it is unlikely that the arrhythmias 
reported after dosing with GSK3039294 in Part A are attributable to its single dose 
administration at 600 mg or 1200mg.

INTRODUCTION
GSK2315698 (CPHPC), crosslinks serum amyloid P component (SAP) resulting in 
depletion of SAP from the plasma, but needs to be given parenterally. GSK3039294 is a 
pro drug of CPHPC that has been developed in order to offer the potential of an orally 
available alternative to parenteral CPHPC for plasma SAP depletion prior to use of anti 
SAP mAb in the treatment of systemic amyloidosis. 
Systemic amyloidosis is a clinical disorder caused by progressive accumulation of 
insoluble, misfolded deposits of normally soluble precursor proteins (amyloid) in the 
extracellular matrix of target organs (kidney, liver, heart, spleen). Amyloid deposition is 
responsible for progressive and usually relentless organ dysfunction, failure and almost 
always death. 
Although the nature of the misfolded culprit protein may vary with the type of systemic 
amyloidosis, (20 different proteins have been reported in the different forms of the 
disease), they all share a common cross-β structure, they are derived from normally 
soluble precursor proteins and amyloid deposits are always decorated with SAP.
SAP is a normal, non fibrillar, plasma glycoprotein circulating at 20-40 mg/L. Its 
circulating concentration is not affected in health and disease including amyloidosis. SAP 
is a normal constituent of the extracellular matrix located on the microfibrillar mantle of 
elastic fibers throughout the body and in the lamina rara interna of the glomerular 
basement membrane. However the amount of SAP in these normal tissue sites is 
extremely low compared to the fluid phase SAP. In systemic amyloidosis, SAP 
accumulates in amyloid deposits bound to fibrils and in equilibrium with fluid phase SAP 
pool. In patients with extensive systemic amyloidosis, as much as 20g of SAP may be 
bound in amyloid deposits.
CPHPC is being developed in an obligate therapeutic parternship with anti-SAP 
monoclonal antibodies. CPHPC or GSK3039294 would be used to acutely deplete plasma 
SAP to enable subsequent safe administration of an anti-SAP monoclonal antibody 
(mAb). Binding of the antibody to residual SAP on amyloid deposits triggers their 
removal [Richards, 2015].

Study Rationale
GSK3039294 has been developed in order to offer an orally available alternative to 
parenteral CPHPC for plasma SAP depletion prior to use of anti SAP mAb in the 
treatment of systemic amyloidosis. 
This phase 1 study is intended to study safety, tolerability and PK profile of 
GSK3039294 in humans. It is expected that GSK3039294 will, after oral administration, 
release CPHPC in the circulation and thereby reduce plasma SAP to a level considered 
sufficient for safe administration of anti-SAP mAb (currently a target of below 2mg/L 
with IV CPHPC administration).
CPHPC PK/PD has been studied in both healthy volunteers and patients. A PK/PD model 
taking into account the various compartments, the equilibrium between amyloid bound 
SAP and plasma SAP, the affinity for CPHPC and elimination rate of the complex has 
been established. This model will be used in the present study for determination and 
comparison of the PK/PD profile of the prodrug with the profile of CPHPC [Sahota, 
2015].
Past data with CPHPC have shown that the PK /PD relationship (SAP depletion) 
observed in healthy volunteers is predictive of that in patients with systemic amyloidosis. 
The Study will therefore include healthy volunteers for single and repeat ascending doses 
and determination of PK parameters of the GSK3039294. A group of patients with 
systemic amyloidosis will be included and treated with a dose predicted to be active in 
order to verify that transformation of GSK3039294 is similar in patients and healthy 
volunteers and leads to plasma SAP depletion expected with similar exposures to 
CPHPC.
2.2.
Brief Background
CPHPC has been used in humans in order to decrease circulating SAP. In previous 
academic-sponsored studies patients with systemic amyloidosis, an infusion of CPHPC at 
doses between 0.25-6 mg/kg/day resulted into a rapid and consistent depletion of 
circulating SAP in all subjects. The most common daily dose for long term use was 1 
mg/kg. The treatment was reported to be safe and well tolerated. Some patients with 
systemic amyloidosis were treated for up to 104 weeks at 1mg/kg (given in 2 daily sc 
administrations). Subcutaneous CPHPC administration sometimes led to minor local 
stinging and bruising at the injection site. 
PK/PD studies with CPHPC have been conducted by GSK in both in healthy volunteers 
and patients with systemic amyloidosis after i.v. and s.c. administration. In all cases an iv 
regimen CPHPC decreased plasma SAP concentrations to 2 mg/L. In patients with 
systemic amyloidosis the time to nadir was longer and greatly dependent on the amyloid 
load and liver involvement. The time to plasma recovery was also dependent on amyloid 
load and took longer in patients with amyloid deposits. This indicates that most of the 
newly produced SAP is distributed to amyloid deposits before repleting the circulating 
compartment. As CPHPC is renally cleared the dose is corrected for renal function

Treatment Arms and Duration
4.2.1.
Part A (single dose escalation in healthy volunteers)
Part A is a single dose, open label, dose escalation study conducted in healthy volunteers 
and will evaluate safety, tolerability, and PK of the compound including 
biotransformation of GSK3039294 into active CPHPC.
Two cohorts of subjects will be enrolled to provide data from 6 subjects per cohort and 
up to 4 different doses (2 dose levels per cohort) of GSK3039294 will be tested.
Doses will be administered to Cohorts using a sentinel dosing approach as described 
below. Subjects will be admitted to the unit on Day -1, following the dose on Day 1 
subjects will remain in-house until Day 4. Wash-out will take place from Day 5 to Day 
14.
Providing a review of the data from each dose (safety data: AE, vital signs, ECG and 
laboratory safety test and PK data up to 48 h etc) is favourable, the next dose level will be 
administered. Cohort 1 will be used for 2 dosing periods (Doses 1 and 2), Cohort 2 will 
also be used for 2 dosing periods (Doses 3 and 4).  A review of the data will always be 
conducted prior to the administration of the next dose level.
The planned doses for Dose levels 2, 3 and 4 may be modified based on emerging safety, 
tolerability and PK data. The number of dosing periods may be reduced or extended 
depending on emerging data. Replacement subjects in either Cohort do not need to have 
received the first dose prior to receiving the second dose.
Sentinel dosing:  For all dose levels the subsequent subject will be dosed approximately 
24 hrs after the preceding subject if there are no safety or tolerability concerns. The 
remaining subjects receiving the same dose within the cohort will receive the dose 
approximately 24hrs after the subsequent subject at intervals no less than 1hr apart.

Study Design for Healthy Volunteer Subjects Single Dose (Cohorts 1 
and 2)
All data obtained from this study will be included in the existing PK model established 
from completed studies with CPHPC [Sahota, 2015] and will inform the dose selection 
for the next cohort/dosing session. 
At the end of this single dose part, all PK data will be analysed (see Section 9.3.2) and 
reviewed together with all available safety data.
The study drug will be further evaluated in Parts B and C, unless following Part A it is 
determined that:

If the safety profile is acceptable however the calculated bioavailability would 
mean that even following dosing of GSK3039294 at a maximum dose (which 
does not exceed pre-clinical safety exposure limits), insufficient CPHPC would be 
generated to be an effective depleter of plasma SAP. 


2014N218204_03

201664
24

If the safety profile restricts the maximum well tolerated dose level to one that 
does not generate sufficient CPHPC to be an effective depleter of plasma SAP. 
In this situation the study may be terminated.
4.2.2.
Part B (repeat dose escalation in healthy volunteers)
Part B is repeat dose, open label, dose escalation conducted in healthy volunteer subjects 
and will evaluate the safety, tolerability, PK, pharmacodynamics of repeat dosing (7 day 
in Cohort 3, 21 day in Cohort 4) of GSK3039294. In addition to PK, plasma SAP levels 
will be measured at time points as in the Time and Events table (Section 7.1.1) to 
determine the ability of GSK3039294 to decrease plasma SAP levels to aid prediction of 
the optimal clinical dose.
4.2.2.1.
Sentinel Dosing in Part B
In each individual study cohort in Part B, a sentinel subject will complete all dosing days 
up to and including Day 7. If there are no clinically concerning safety or tolerability 
issues observed, the rest of the subjects within the cohort can be dosed. 
If the safety data from the sentinel subject is deemed to be equivocal, a second (and 
subsequent) subjects will complete all dosing days individually, up to and including Day 
7, at the discretion of the Investigator in consultation with the GSK study team.
4.2.2.2.
7 Day Repeat Dosing (Cohort 3)
In a group of healthy volunteers, sufficient subjects will be enrolled to ensure a minimum 
of 6 subjects complete all study procedures (including evaluation of food-effect) 
associated with 7 days repeat dosing administration.The dose will be one that is expected 
to be well tolerated based on the single dose data and predicted to not exceed exposure 
limits based on single dose PK. 
A food effect exploration will be conducted at Days 4 and 5 of this cohort once the 
investigator is satisfied with the safety data from the sentinel subject(s). To evaluate a 
potential food effect, GSK3039294 will be administered under fasted and then under fed 
conditions (please see SRM for details of meals), and PK samples will be taken to 
investigate the food effect on the PK.
Cardiac Safety Review of Cohort 3
Given that all cardiac arrhythmic events after single dose administration of GSK3039294 
in Part A (where there were detectable levels of plasma CPHPC) were relatively acute 
and observed between approximately 4 to 7 hours after tmax of CPHPC and when no 
GSK3039294 was detectable, and given steady state is expected to be reached after 
approximately 5 days of repeat dosing, 7 day continuous cardiac telemetry in Cohort 3 is 
deemed to be of sufficient duration to detect any potential cardiac arrhythmias associated 
with repeat dosing of GSK3039294.

201664

On completion, in addition to full safety review, a cardiac safety review will be 
performed where individual subject telemetry data will be reviewed in relation to the PK 
data of GSK3039294 and CPHPC.
4.2.2.3.
21 Day Repeat Dosing (Cohort 4a)
In a group of healthy volunteers sufficient subjects will be enrolled to ensure 6 
completers, the study drug will be administered repeatedly for a total of 21 days. 
The dose level and / or dosing regimen may be adjusted (up or down)  once during the 21 
days providing a review of the data from the starting dose (safety data: AE, vital signs, 
ECG, laboratory safety tests and PK – all obtained once steady state has been achieved) is 
favourable. If the dose is to be altered, this will be done no later than Day 16 in order to 
achieve a new steady-state at Day 21. The predicted maximum daily dose administered 
will not exceed pre-clinical safety exposure limits.
Initiation of Cohort 4a: Cohort 4a will only be initiated if the conclusion of the safety 
review from Cohort 3 demonstrates an acceptable safety profile associated with the repeat 
administration of GSK3039294 for 7 days. 
Individual subjects in Cohort 4a can be withdrawn from the study at the discretion of the 
Investigator in consultation with the GSK study team if individual subject safety review 
at Day 7 demonstrates any AEs which are deemed to be equivocal or clinically 
concerning. Affected subject(s) should be followed-up, at the discretion of the 
Investigator, as per local practice.
Data from cohorts 3 and 4a are expected to provide a good evaluation of the safety, 
tolerability and repeat-dose PK. The data will be evaluated using the PK/PD model to 
identify an optimal clinical dose (see Section 9.3.2.1). However, if it is determined that 
further investigation of dose levels are required before progressing to Part C (e.g. if the 
observations in cohort 4a are different from those which the PK /PD modelling 
predicted), then recruitment into Cohort 4b may be initiated.
4.2.2.4.
21 Day Repeat Dosing (Cohort 4b – optional, only if required)
In a group of healthy volunteers, sufficient subjects will be enrolled to ensure a minimum 
of 6 completers, the study drug will be administered repeatedly for a total of 21 days. 
Based on data from Cohorts 3 and 4a, dose levels will be selected for further 
investigation in a further cohort of healthy volunteers (recruitment to ensure 6 
completers). For this purpose the compound will be dosed for 21 consecutive days. The 
dose level and / or dosing regimen may be adjusted (up or down)  once during the 21 
days providing a review of the data from the starting dose (safety data: AE, vital signs, 
ECG, laboratory safety tests and PK – all obtained once steady state has been achieved) is 
favourable. If the dose is to be altered, this will be done no later than Day 16 in order to 
achieve a new steady-state at Day 21. The predicted maximum daily dose administered 
will not exceed pre-clinical safety exposure limits.

assess the ability of GSK3039294 to maintain this level over 21 days in patients with 
systemic amyloidosis.
Safety and tolerability will also be evaluated

Sentinel Dosing in Part C
Renal Amyloidosis Sentinel Subject: A sentinel systemic amyloidosis patient (n=1) 
with known renal involvement and an estimated GFR ≥ 60 ml / min, but with no known 
cardiac involvement, will be dosed repeatedly with GSK3039294 for the full 21-day 
period before dosing any other patients begin. Following this, dosing of other patients 
with renal involvement (with an eGFR > 50 mL / min) but with no cardiac involvement 
can be initiated, provided no concerning safety signals are detected in this sentinel 
patient.
Cardiac Amyloidosis Sentinel Subject: Once the sentinel renal patient has successfully 
completed dosing, a sentinel cardiac amyloidosis patient (n=1) with eGFR≥ 60 mL / min 
& LV Ejection Fraction (EF)  ≥ 50% will be dosed repeatedly with GSK3039294 for the 
full 21-day period. Following this, dosing of any other patients with cardiac involvement 
(NYHA ≤2) can be initiated provided no concerning safety signals are detected in the 
sentinel cardiac patient.

Type and Number of Subjects
In Part A, sufficient healthy volunteers will be enrolled to ensure 6 subjects per cohort 
have completed the in-patient phases.
In Part B, sufficient healthy volunteers will be enrolled to ensure a minimum of 6 
subjects per cohort have completed the in-patient phases with all study procedures.
Subjects who participate in Part A will be eligible to participate in Part B at the discretion 
of the Investigator. 
In Part A and B of the study, if subjects prematurely discontinue, replacement subjects 
may be enrolled and assigned to the same cohort at the discretion of the Sponsor in 
consultation with the investigator. Replacement subjects do not need to have received the 
first dose for a given cohort to join the study in the second cohort.
In Part C, a minimum of 12 patients with systemic amyloidosis (which may include
those with known cardiac amyloid involvement) will be enrolled.  If subjects prematurely 
discontinue, replacement subjects may be enrolled at the discretion of the Sponsor in 
consultation with the investigator.  
Additional subjects/cohorts may be enrolled to allow for further evaluation of a given 
dose or for evaluation of additional dose levels. 
4.4.
Design Justification
CPHPC has had a good safety and tolerability profile in clinical studies to date.
GSK3039294 is expected to release CPHPC in the circulation. The measures of this are 
pharmacokinetic and pharmacodynamic (SAP depletion) and therefore no control group 
is included. Subjects treated with placebo are also not included because an assessment of 
the precision of causality that feasible numbers of subjects would give is poor (see 
Section 9.2). 
Previous data shows that the PK/PD of CPHPC in healthy volunteers is predictive of that 
in the target patient population, hence the inclusion of this group in the study.

Once an effective and well-tolerated regimen has been established in healthy volunteers, 
this will be tested in patients with systemic amyloidosis to confirm that the PK PD of the 
pro drug.   
Part A will allow assessment of safety, tolerability and PK including biotransformation 
of GSK3039294 into active CPHPC of single doses of GSK3039294. If the absorption of 
GSK3039294 and subsequent biotransformation of GSK3039294 to CPHPC is sufficient 
then repeat dosing will be investigated in Part B.
Part A washout period:  In Part A of the study, subjects will receive 2 dose levels of 
GSK3039294, and the washout between doses will be appoximately 14 days.  This 
washout period will allow a thorough investigation of safety, tolerability and PK, 5 days 
is considered sufficient to eliminate any systemic exposure carryover between dosing 
periods.
Part B will allow assessment of safety, tolerability and PK including biotransformation 
of GSK3039294 into active CPHPC of repeat doses of GSK3039294 and PD (depletion 
of plasma SAP). PK and PD data will be compared within a subject following repeat 
dosing and dose escalation and regimen adjustments. If the exposure to CPHPC and the 
resulting depletion of SAP is sufficient the repeat dosing of patients with systemic 
amyloidosis will be investigated in Part C.
The duration of 7 days for Cohort 3 Part B was selected as steady state is predicted to be 
achieved in this time. The duration of 21 days for Cohorts 4a and 4b in Part B was 
selected to reflect the likely duration of treatment needed for clinical use with the anti 
SAP monoclonal antibody. 
Part C will confirm the ability of GSK3039294 (given at the predicted pharmacological 
dose determined from Part B) to decrease plasma SAP to a level suitable for mAb 
administration in subsequent studies and its ability to maintain this level over 21 days in 
patients with systemic amyloidosis. Also, safety and tolerability of the optimal clinical 
dose of GSK3039294 will be evaluated in systemic amyloidosis patients which may 
include those with known cardiac amyloid involvement.
The duration of 21 days for Part C was selected to reflect the likely duration of treatment 
needed for clinical use with the anti SAP monoclonal antibody.
Pharmacogenetics: Although human esterases can exhibit a high level of redundancy for 
specific substrates, there are particular prodrugs, such as oseltamivir which have been 
found to be preferentially metabolized by a specific esterase (i.e. carboxyesterase (CES)-
1). Therefore, in all three parts of the study, blood samples will be collected from healthy 
volunteers and patients, and stored for retrospective SNP (single nucleotide 
polymorphism) array analysis in the event of unexpected PK profile patterns for 
GSK2315698 (CPHPC) and / or plasma SAP being observed. This might be indicative of 
either slower or accelerated pro-drug CPHPC activation which might be explained by the 
presence of a germline SNP affecting a specific esterase-encoding gene(s) (see Section 
7.6 & Appendix 3).

Dose Justification
This study is planned to test single doses of GSK3039294 and repeat doses up to the 
maximum tolerated dose or the maximum allowable dose based on pre-clinical findings. 
The intention is to target the PK exposure of CPHPC seen in previous clinical studies 
producing the SAP depletion required for future studies with anti-SAP mAb.
Part A
The starting dose in Part A is planned to be 200mg of GSK3039294. This dose is selected 
using the PK/PD model that was developed for CPHPC (active molecule) [Sahota, 2015], 
adjusted for the oral absorption of GSK3039294 and the conversion of GSK3039294 to 
CPHPC. PK in pre-clinical species (rat and dog) show a very fast and complete 
conversion of GSK3039294 into CPHPC. Several marketed pro-drugs (viread, cerebyx, 
spectracef, hepsera) have either a fast and complete conversion into the active compound, 
or a tmax of the active compound that is within a few hours consistent with fast 
conversion.
Assuming fast and complete oral absorption of GSK3039294 and  fast and complete 
conversion of GSK3039294 into CPHPC, then both processes are described by a single 
first-order process (Ka) and high bioavailability (F). For the purposes of dose estimation 
Ka and F have been assumed to be high: 1.3/hr and 100%, as this will result in the highest 
exposures to CPHPC possible. Distribution and elimination of CPHPC is expected to be 
the same, regardless of IV administration of CPHPC or oral administration of the pro-
drug (GSK3039294). Therefore, distribution and elimination parameters, as well as 
between subject variability, were set to the estimates from the analysis of CPHPC itself.
The NOAEL for GSK3039294 in preclinical species is set to 1000 mg/kg/day, which is 
associated with CPHPC exposure of AUC[0-24] of 250 g.hr/mL and Cmax of 
22.1 g/mL. In the rat cardiovascular changes were observed at concentrations of about 
6 g/mL. These changes were not observed in studies with dogs, and are considered 
species specific, however, to confirm there are no cardiovascular changes in clinic, the 
SD dose escalation in Part A will start at a dose that is predicted to result in CPHPC 
concentrations that are lower than 6 g/mL.
Using the PK/PD model the concentration-time profiles of CPHPC after a single dose of 
GSK3039294 were simulated, and Cmax and AUC[0-inf] were derived. For a dose of 
200 mg, this resulted in a predicted AUC[0-inf] of 14.5 g.hr/mL  (95% CI of 9.5-22.4 
g.hr/mL) and a predicted Cmax of 3.4 g/mL (95% CI of 2.1-5.0 g.hr/mL).
The next doses in Part A will be determined based on the data of the preceding dosing 
sessions. All available PK data will be analysed (see Section 9.3.2.1), and the next dose 
will be such that the median Cmax will be about 6 g/mL, and the predicted 95% CI will 
not exceed preclinical Cmax and AUC limits.
The highest dose in Part A will not exceed pre-clinical safety exposure limits of 
AUC[0-24] of 250 g.hr/mL and Cmax of 22.1g/mL.

Part B
The dose level for Cohort 3 in Part B will be determined based on the PK data obtained in 
Part A, by analysing all available PK data from Part A and subsequently predicting 
concentration-time profiles at steady state after repeat dosing. Table 5 shows examples of 
dose levels and frequencies with predicted AUC[0-24] and Cmax at steady state, using 
the PK/PD model that was developed for CPHPC (active molecule) [Sahota, 2015], 
adjusted for oral absorption and conversion of GSK3039294 into CPHPC. The PK data 
from Part A will be used to obtain estimates for Ka and F.

The dose levels for subsequent cohorts in Part B will be determined based on the PK data 
from Part A (single dose), and cohort 3 in Part B (multiple dose). All available PK data 
will be analysed (see Section 9.3.2.1). The dose levels and dosing frequencies will be 
chosen such that the predicted 95% CI of Cmax and AUC at steady state will not exceed 
preclinical Cmax and AUC limits (22.1 g/mL and 250 g.hr/mL, respectively).

Part C
GSK3039294 will be administered at the predicted optimal clinical dose for 21 days. This 
dose will be determined using the PK/PD model that was developed for CPHPC (active 
molecule) [Sahota, 2015]. Using all available PK and plasma SAP (PD) data from Parts 
A and B, the model will be adjusted for the oral absorption of GSK3039294 and the 
conversion of GSK3039294 to CPHPC. Plasma concentration-time profiles of CPHPC as 
well as the plasma SAP time course after repeat dosing with GSK3039294 will be 
predicted in order to determine the optimal clinical dose and dose frequency. The dose 
level and frequency will be chosen such that the predicted 95% CI of Cmax and AUC at 
steady state will not exceed preclinical Cmax and AUC limits (22.1 g/mL and 250 
g.hr/mL, respectively). See Section 9.3.2.1 for further details of the analysis.
4.6.
Benefit:Risk Assessment
GSK3039294 is an oral prodrug of CPHPC (GSK2315698). CPHPC has been associated 
with a good safety profile in clinical studies to date (see Investigator’s Brochure)
There is no clinical benefit to either healthy volunteer subjects or systemic amyloidosis 
patients in achieving plasma SAP depletion during any Part of the study.  
A NOAEL of 1000 mg/kg/day has been identified in Wistar rats based upon adverse 
findings as regards urine biochemistry in the absence of any identified pathological 
changes within the kidney using light microscopy techniques. Close monitoring of 
plasma and urine biochemical parameters, including renal function and proteinuria 
surveillance, will be performed in all Parts of the study including in systemic amyloidosis 
patients in Part C (see Section 7.1 & Section 7.5).
The release of CPHPC from GSK3039294 will be accompanied by the release of 2 
molecules of formaldehyde. Formaldehyde is generated by endogenous human basal 
metabolism is substantial amounts, (approximately 50g per day).  For a dose of 1.2 g per 
day (a dose not likely to be exceeded in this study), the total amount of formaldehyde
generated would be around 120mg. In addition, a number of prodrug compounds such as 
Viread, Cerebyx, Spectracef and Hepsera releasing up to 120mg/day of formaldehyde
have been described in the literature and there have been no specific human toxicology 
findings [Dhareshwar, 2008] associated with this upper level of formaldehyde release 
from their metabolism Exogenous production of formaldehyde from either food stuffs or 
licensed prodrugs is not known, to date, to cause detectable organ or physiological 
dysfunction in humans.
Summaries of findings from non-clinical studies conducted with GSK3039294 can be 
found in the Investigator’s Brochure. Summaries of findings from both clinical and non-
clinical studies conducted with GSK2315698 can be found in the Investigator’s Brochure.

Refer to Section 4.5
Maximum dose is likely to be below 1.2g,

Small volume nose bleeds have been noted 
in a few patients which have been self-
limited and not associated with any 
evidence of thrombocytopenia or 
coagulopathy. 
The relationship to GSK2315698 is unclear 
but subjects are closely monitored for 
bleeding.

Monitoring of haemoglobin & platelets
Potential food effect on PK of GSK3039294 
(and subsequent GSK2315698)
Based on the physical-chemical properties 
of GSK3039294 it is not expected that the 
PK will be affected by food. However, as it 
is not feasible to give bid or tid dosing 
under fasted conditions, administration of 
GSK3039294 in Weeks 2 and 3 of Part B 
and in Part C will be without restrictions 
with respect to meal times.
A potential effect of food will be explored 
in this study (Cohort 3 of Part B). If the 
food effect exploration shows an effect of 
food on the PK of GSK3039294 (and 
subsequently GSK2315698), a formal food 
effect study will be considered.

Preclinical finding of potential 
nephrotoxicity of GSK3039294
Following 4 weeks oral dosing in rats, 
minor changes in urine composition 
comprising of low pH in males given 300 
mg/kg/day (mean pH was 5.8 and 6.4 at 
1000 mg/kg/day or control respectively) and 
females given 1000 mg/kg/day (mean pH 
was 5.6 and 5.9 at 1000 mg/kg/day or 
control respectively), an increase in total 
protein excretion in both sexes given 1000 
mg/kg/day (up to 1.48X control) and 
increased specific gravity, creatinine and 
glucose output for males given 1000 
mg/kg/day (1.02X, 1.14X and 1.22X 
control, respectively). These changes were 
considered not biochemically concerning, 
and were not associated with any renal 
pathological findings on H&E staining of rat 
kidney paraffin sections. 
Additionally, no change in any urinalysis 
parameters was observed in the dog 28 day 
toxicity study with GSK3039294 at doses 
1000 mg/kg/day.
Overall, in the absence of any renal 
pathological changes under light 
microscopy, the significance of these rat 
renal biochemical changes is unclear.
Precautions as listed in Section 7.4 to detect 
signals of potential nephrotoxicity from 
GSK3039294 in humans at the earliest time 
point possible during both single and repeat 
dose administration in both healthy 
volunteer subjects and systemic amyloidosis 
patients.

Preclinical finding of haematologic effects 
associated with GSK2315698
In toxicology studies using IV 
GSK2315698, minor reductions in red cell 
parameters were observed in female dogs 
given 200 mg/kg/day for 4 weeks. A 34% 
increase in platelet count was seen in rats 
receiving 400 mg/kg/day for 8 days. 
Some trends (haemoglobin increased; white 
cells and platelets decreased) within the 
reference range were observed in a single 
dose study in healthy volunteers 
(CPH113776). The clinical significance of 
these observations is not clear and similar 
changes were not observed in the patient 
study (CPH114527).
Therefore, at this time, it is felt to be very 
unlikely that GSK2315698 (CPHPC) has 
any haematological toxicity properties in 
human subjects.
Haematological parameters will be 
monitored in the clinic.
Dosing not to exceed the existing NOAEL.
Preclinical finding of testicular changes 
associated with GSK2315698
In one study in male rats (but not in another 
similar study), testicular changes 
(seminiferous tubular degeneration/atrophy, 
reduced spermatozoa, shedding of 
spermatogenic cells) were observed at the 
highest dose tested (400 mg/kg/day for 28 
days). No testicular changes were observed 
in a rat 26 week study (terminated at week 
The highest dose of GSK3039294 will not 
yield exposures of GSK2315698 exceeding 
a predicted mean AUC0-24 of 145 ug*h/mL 
and Cmax of 6.05 ug/mL based on the 
NOAEL in the rat 28 day IV repeat dose 
studies, and therefore the potential risk to 
humans during the proposed short term 
dosing is considered very low

One healthy volunteer subject had two 
separate arrhythmic events which consisted

single 5-beat episode of AIVR 
approximately 12 hours later.

4.6.2.
Benefit Assessment
No medical benefit can be expected by participating in this study.
4.6.3.
Overall Benefit:Risk Conclusion
GSK3039294 is an oral prodrug of CPHPC, as such it is expected to release CPHPC after 
oral administration. Previous clinical experience with CPHPC shows it has a good safety 
and tolerability profile therefore we do not anticipate safety issues linked to the release of 
the active moiety.
At this time, although the cardiac arrhythmias reported in Part A are unlikely to be 
attributable to single dose administration of GSK3039294 at either 600mg or 1200mg, as 
a precaution, and to further assess and confirm this conclusion, the cardiac safety 
monitoring of healthy volunteer subjects during repeat dose administration of 
GSK3039294 for 7 consecutive days in Cohort 3 Part B has been enhanced (see Section 
7.3.7.), and also in systemic amyloidosis patients in Cohort 5 Part C who are known to 
have cardiac amyloid involvement (see Section 7.3.8.).
Biotransformation from prodrug into active will release 2 molecules of formaldehyde. 
There is precedent of licensed prodrugs releasing formaldehyde with no associated 
toxicity on a background that formaldehyde is physiologically metabolised very rapidly 
within the systemic circulation (EFSA Journal, 2014; 12(2):3550). 
Preclinical signs of potential nephrotoxicity were observed at very high doses which are 
unlikely to be reached in the clinic, however monitoring of renal function will be 
performed in the study in order to detect any potential changes. 
There will be no medical benefit to healthy volunteers or patients with systemic 
amyloidosis being treated with GSK3039294 alone. The design of the study, schedule of 
assessments, and oversight mean that any risks to participants are minimised including 
those which might potentially affect the kidney and heart, and therefore the clinical study 
is justified.

Screening/Baseline/Run-in Failures
Screen failures are defined as subjects who consent to participate in the clinical trial but 
are never subsequently enrolled. In order to ensure transparent reporting of screen failure 
subjects, meet the Consolidated Standards of Reporting Trials (CONSORT) publishing 
requirements, and respond to queries from Regulatory authorities, a minimal set of screen 
failure information is required including Demography, Screen Failure details, Eligibility 
Criteria, and any Serious Adverse Events.

Withdrawal/Stopping Criteria
The following actions must be taken in relation to a subject who fails to attend the clinic 
for a required study visit:

The site must attempt to contact the subject and re-schedule the missed visit as soon 
as possible. 

The site must counsel the subject on the importance of maintaining the assigned visit 
schedule and ascertain whether or not the subject wishes to and/or should continue in 
the study. 

In cases where the subject is deemed ‘lost to follow up’, the investigator or designee 
must make every effort to regain contact with the subject (where possible, 3 
telephone calls and if necessary a certified letter to the subject’s last known mailing 
address or local equivalent methods). These contact attempts should be documented 
in the subject’s medical record. 

Should the subject continue to be unreachable, only then will he/she be considered to 
have withdrawn from the study with a primary reason of “Lost to Follow-up”. 
Non-compliance to the study regimen or withdrawal of consent (no reason has to be 
given by the individual subject) will lead to the removal from the study. An individual 
subject may withdraw from study treatment at any time at his/her own request, or may be 
withdrawn at any time at her own request, or at the discretion of the investigator for 
safety, behavioural or administrative reasons. If a subject 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 entire study will be terminated if the sponsor (GSK) 
stops the study at any stage.
Individual subjects may be withdrawn at the investigator’s discretion at any time during 
the study, provided there is a valid and confirmable clinical reason. The presence of 
severe AEs predefined as stopping criteria below in Section 5.5, or SAE as defined in
Appendix 3, will lead to the withdrawal of an individual subject. Withdrawn subjects will 
be replaced by new subjects as per the guidance in Section 6.4
5.4.1.
Cardiovascular Safety Stopping Criteria
1. New onset or worsening symptoms of cardiac ischemia which is reasonably 
attributable to GSK3039294
2. Development of decompensated or uncontrolled cardiac failure which is 
reasonably attributable to GSK303294.
3. Systolic blood pressure > 170 mmHg as an average of triplicate readings taken at 
rest over 15 minutes on three consecutive days at any time after administration 
and is reasonably attributable to GSK3039294.
4. Healthy Volunteers & Amyloidosis Patients without bundle branch block:
QTcF > 500 msec, (or a change from baseline of QTcF > 60 msec on a 12-lead

5. Systemic Amyloidosis patients with bundle branch block - if baseline QTcF < 
450 msec: QTcF > 500 msec on a 12-lead ECG at any time after administration of 
GSK3039294; If baseline QTcF 450-480 msec: QTcF > 530 msec at any time 
after drug administration and is reasonably attributable to GSK3039294, as an 
average of triplicate readings (see Section 5.4.3).
6. Any cardiovascular SAE as predefined in Appendix 4 after drug administration 
and is reasonably attributable to GSK3039294
Please also see Section 5.4.4. Cardiac Arrhythmia stopping criteria

5.4.4.
Cardiac Arrhythmia Stopping Criteria
All cardiac arrhythmias in individual subjects will be reviewed by the Investigator in 
consultation with the Medical Monitor at the earliest possible opportunity after the event, 
and will also be reviewed by a cardiologist where it is deemed appropriate to do so by the 
Investigator in consultation with the Medical Monitor on a case-by-case basis.
A clinically concerning cardiac arrhythmia in this study is any type of arrhythmia or 
divergent QRS complex morphology that is deemed by the Investigator to be reasonably 
attributable to GSK3039294 - rather than within normal variation for each type of 
affected subject receiving repeat dose GSK3039294; i.e. healthy volunteer subjects in 
Part B, or systemic amyloidosis patients with known cardiac involvement Part C.
Furthermore, a clinically concerning arrhythmia is an adverse event which is deemed by 
the Investigator in consultation with the Medical Monitor to be of sufficient temporal 
duration and / or character to potentially affect subject safety. 
Detection of the following during baseline assessment or following administration of 
GSK3039294 will lead to withdrawal:
a). Sustained (≥ 10 beats) / symptomatic monomorphic ventricular tachycardia (VT), or 
rapid polymorphic VT; b). Complete heart block; c). Brady arrhythmias deemed 


2014N218204_03
CONFIDENTIAL
201664
50
clinically concerning by the Investigator in consultation with the Medical Monitor (i.e. 
except physiological bradycardia or first degree heart block).
Additional cardiac arrhythmic events could include, but are not restricted, to: 

A sustained arrhythmia (i.e. ≥30 seconds) except physiological bradycardia.

A non-sustained wide-complex tachyarrhythmia ≥ 100 / minute that is:
o
accompanied by symptoms or other new ECG changes (e.g. new ST 
depression)
o
repetitive (e.g. repeated short salvos)
o
Greater than 10 seconds in duration
Subjects who either have a clinically concerning arrhythmic event during the study, or 
where there is electrophysiological diagnostic uncertainty on cardiac telemetry / ECG, 
must be withdrawn from the study, and should have an immediate cardiac troponin level 
evaluated using a high-sensitivity point-of-care assay as outlined in Section 7.3.7 & 
Figure 5, below. 
Affected subjects should be referred to the local cardiology service and the Medical 
Monitor should be informed as soon as possible.

doses of GSK3039294 in Parts B & C based on Arrhythmia 
Characterization
In Part C, the patient’s amyloidosis physician should be informed as soon as possible 
after any type of cardiac adverse event, by the Medical Monitor, irrespective of the 
patient’s cardiac amyloid status at Screening.
5.4.5.
Renal Stopping Criteria
The presence of any of the following which are reasonably attrituble to GSK3039294 will 
be nominally categorised as a severe adverse event and will constitute individual stopping 
criteria for subjects:
Healthy volunteers (Part A or Part B): 

Spot Urine Protein Creatinine (UPC) ratio > 0.5
Healthy volunteers (Part A or Part B) & Patients (Part C):

Increase in serum creatinine (ΔsCr) of 0.3 g/dL from baseline (or an increase of 50% 
at any time if the baseline is > 0.6 g/dL)

Detectable glycosuria in the presence of concomitant normoglycaemia


2014N218204_03
CONFIDENTIAL
201664
52

Hypophosphataemia (less than 0.8mmol/L)

Metabolic acidosis 
All abnormal results should be confirmed within 24 hours before individual subject 
stopping criteria are implemented.
5.4.6.
Stopping Criteria Based On Disease Progression in Systemic 
Amyloidosis Patients in Part C
In Part C, individual systemic amyloidosis patients can be withdrawn at any time during 
the study where the investigator has a reasonable level of clinical suspicion that the 
patient's underlying systemic amyloidosis is worsening (including worsening cardiac 
dysfunction in those patients known to have cardiac amyloid involvement). In this 
setting, the investigator in consultation with the Medical Monitor must refer the patient to 
their primary hospital physician for further consultation and appropriate diagnostic tests
5.5.
Stopping Criteria for the Entire Healthy Volunteer or Patient 
Study Groups

If an SAE occurs that the investigator believes is reasonably attributable to IMP, in 
any subject at any one dose level of GSK3039294, continuation of the study will be 
temporarily halted and no further subjects will be dosed until a full safety review of 
the data has taken place.

If the same severe adverse event is observed in two subjects across all study parts, 
and is reasonably attributable, in the opinion of the investigator, to GSK3039294, the 
study will be temporarily halted and no further subjects will be dosed until a full 
safety review of the study has taken place. 

If the study is temporarily halted, relevant reporting and discussion with the Medical 
Monitor, relevant GSK personnel, and with the applicable regulatory authority will 
take place prior to any resumption of dosing

Every effort will be made to take a blood sample for pharmacokinetic analysis from 
each affected individual at the time of any of the adverse events described above
5.6.
Subject and Study Completion
A completed subject is one who has completed all phases of the study including the final 
follow-up visit.

STUDY TREATMENT
6.1.
Investigational Product and Other Study Treatment
The term ‘study treatment’ is used throughout the protocol to describe any combination 
of products received by the subject as per the protocol design. Study treatment may 
therefore refer to the individual study treatments or the combination of those study 
treatments.
Study Treatment
Product name:
GSK3039294 Capsules
Dosage form:
Capsules 
Unit dose 
strength(s)/Dosage 
level(s):
20 to 200mg
Route of Administration
Oral 
Dosing instructions:

6.2.
Treatment Assignment
This is an open-label, non-randomised study with no active or placebo control.
GSK3039294 doses will be administered sequentially, as detailed in Section 4.1, and will 
be based on the review of safety, PK and PD data from previous cohorts, dosing sessions 
and study parts. 
6.3.
Planned Dose Adjustments
This protocol allows some alteration from the currently outlined dosing schedule, but the 
maximum daily dose will not exceed pre-clinical exposure limits (Cmax of 22.1 g/mL 
and AUC[0-24] of 250 g.hr/mL).
The decision to proceed to the next dose level of GSK3039294, will be made by the GSK 
Study Team and the investigator based on safety, tolerability and preliminary 
pharmacokinetic and/or pharmacodynamic data (Parts B and C) obtained in at least 6
subjects at the prior dose level (see Section 10.7.1).  The actual doses to be administered 
may be adjusted based on safety, tolerability and preliminary pharmacokinetic and/or 


2014N218204_03
CONFIDENTIAL
201664
54
pharmacodynamic data at previous dose levels; these dose adjustments may involve 
either an increase or a decrease in the planned dose.
The dosing schedule may also be adjusted to expand a dosing cohort to further evaluate 
safety, pharmacokinetic and/or pharmacodynamic findings at a given dose level, or to add 
cohorts to evaluate additional dose levels.  The study procedures for these additional 
subject(s) or cohort(s) will be the same as that described for other study subjects.
6.4.
Blinding
This will be an open-label, non-randomised, dose-escalation study with no active or 
placebo control.
6.5.
Packaging and Labeling
The contents of the label will be in accordance with all applicable regulatory 
requirements.
6.6.
Preparation/Handling/Storage/Accountability
A description of the methods and materials required for preparation of GSK3039294 will 
be detailed in a Study Specific Technical Agreement/Memo (TTS) or Pharmacy Manual 
which will be accompanied by a Quality Agreement.

Only subjects enrolled in the study may receive study treatment and only authorized 
site staff may supply or administer study treatment.  All study treatments must be 
stored in a secure environmentally controlled and monitored (manual or automated) 
area in accordance with the labelled storage conditions with access limited to the 
investigator and authorized site staff. 

The investigator, institution, or the head of the medical institution (where applicable) 
is responsible for study treatment accountability, reconciliation, and record 
maintenance (i.e. receipt, reconciliation and final disposition records).  

Further guidance and information for final disposition of unused study treatment are 
provided in the SRM. 

Under normal conditions of handling and administration, study treatment is not 
expected to pose significant safety risks to site staff.  Take adequate precautions to 
avoid direct eye or skin contact and the generation of aerosols or mists. In the case of 
unintentional occupational exposure notify the monitor, Medical Monitor and/or 
GSK study contact.

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.

6.7.
Compliance with Study Treatment Administration
When the individual dose for a subject is prepared from a bulk supply, the preparation of 
the dose will be confirmed by a second member of the study site staff. 
When subjects 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 subject identification will be confirmed at the time of dosing by a 
member of the study site staff other than the person administering the study treatment.  
Study site personnel will examine each subject’s hands and mouth to ensure that the 
study treatment was ingested.
When subjects self-administer study treatment(s) at home, compliance with GSK3039294 
will be assessed through a dosing record, querying with the subject during the site visits 
and documented in the source documents and CRF.  A record of the number of 
GSK3039294 capsules dispensed to and taken by each subject must be maintained and 
reconciled with study treatment and compliance records.  Treatment start and stop dates, 
including dates for treatment delays and/or dose reductions will also be recorded in the 
CRF.
6.8.
Treatment of Study Treatment Overdose
For this study, any dose of GSK3039294 greater than the agreed dose for a particular 
cohort, dosing session or study part will be considered an overdose.
GSK does not recommend specific treatment for an overdose.
In the event of an overdose the investigator or treating physician should:
1.
Contact the Medical Monitor immediately
2.
Closely monitor the subject for adverse events (AEs)/serious adverse events (SAEs) 
and laboratory abnormalities until GSK3039294 or GSK2315698 (CPHPC) can no 
longer be detected systemically (at least 4 days for GSK2315698 (CPHPC))
3.
Obtain a plasma sample for pharmacokinetic (PK) analysis as soon as possible, but at
least within 7 days from the date of the last dose of study treatment if requested by 
the Medical Monitor (determined on a case-by-case basis)
4.
Document the quantity of the excess dose as well as the duration of the overdosing in 
the CRF.
Decisions regarding dose interruptions or modifications will be made by the investigator 
in consultation with the Medical Monitor based on the clinical evaluation of the subject.
6.9.
Treatment after the End of the Study
Subjects will not receive any additional treatment from GSK after completion of the 
study because the regimens investigated are not designed as study treatments but to 
investigate PK/PD kinetics of various regimens of GSK3039294 dosing.

Lifestyle and/or Dietary Restrictions
6.10.1.
Meals and Dietary Restrictions

In Part A, and during Cohort 3 of Part B on all dosing days, subjects will be required 
to fast from midnight until 3 hours after administration of study treatment (with the 
exception of Day 5 of Cohort 3 in which subjects will be fed). At other times, snacks 
and meals will be provided by the clinical unit.  Water will be allowed as desired 
except for one hour before and after drug administration.

An investigation into a possible food effect will be conducted on Days 4 and 5 of 
Cohort 3 of Part B in this study (This will only be triggered by the Investigator in 
consultation with the Medical Monitor as per Section 4.2.2). On Day 4 subjects will 
be fasted until following the collection of the 4hr post-dose PK sample, on Day 5 
subjects will be fed prior to PK samples being taken. This investigation will inform 
possible further meal restrictions in the study (rest of Part B and Part C).

There are no meal restrictions for Cohorts 4a and 4b of Part B and all of Part C, 
unless the food effect exploration indicates significant effects on PK.
6.10.2.
Caffeine and Alcohol, and Tobacco

During each dosing session, subjects will abstain from ingesting caffeine- or 
xanthine-containing products (e.g., coffee, tea, cola drinks and chocolate) for at least 
24 hours (48 hours for Cohort 3) prior to the start of dosing until collection of the 
final pharmacokinetic and or pharmacodynamic sample during each session. 

Healthy Subjects: During each treatment period, subjects will abstain from alcohol 
for 24 hours (48 hours for Cohort 3) prior to the start of dosing until collection of the 
final PK sample for each in-house session. Subjects will also abstain from alcohol 
for 24 hours prior to screening and follow-up.  At all other times during the study, 
male subjects should have no more than 2 drinks per day and female subjects should 
have no more than 1 drink per day (1 drink is equivalent to 12 g of alcohol: 360 mL 
of beer, 150 mL of wine or 45 mL of 80 proof distilled spirits).

Patients with raised LFT’s at baseline: No alcohol is to be consumed from D-1 
until follow-up assessments are completed

Screening and Critical Baseline Assessments
Cardiovascular medical history/risk factors (as detailed in the CRF) will be assessed at 
screening.
The following demographic parameters will be captured: year of birth, sex, race and 
ethnicity.
Medical/medication/family history will be assessed as related to the inclusion/exclusion 
criteria listed in Section 5.  
Procedures conducted as part of the subject’s routine clinical management e.g. blood 
count and obtained prior to signing of informed consent may be utilized for Screening or 
baseline purposes provided the procedure meets the protocol-defined criteria and has 
been performed in the timeframe of the study.
7.3.
Safety
Planned time points for all safety assessments are listed in the Time and Events Tables
(Section 7.1).  Additional time points for safety tests (such as vital signs, physical exams 
and laboratory safety tests) may be added during the course of the study based on newly 
available data to ensure appropriate safety monitoring.
7.3.1.
Adverse Events (AE) and Serious Adverse Events (SAEs)
The definitions of an AE or SAE can be found in Appendix 4 and Section 12.4
The investigator and their designees are responsible for detecting, documenting and 
reporting events that meet the definition of an AE or SAE. 
7.3.1.1.
Time period and Frequency for collecting AE and SAE information

AEs and SAEs will be collected from the start of Study Treatment until the follow-
up contact (see Section 7.3.1.3), at the timepoints specified in the Time and Events 
Table (Section 7.1).

Medical occurrences that begin prior to the start of study treatment but after 
obtaining informed consent may be recorded on the Medical History/Current 
Medical Conditions section of the CRF.

Any SAEs assessed as related to study participation (e.g., protocol-mandated 
procedures, invasive tests, or change in existing therapy) or related to a GSK product 
will be recorded from the time a subject consents to participate in the study up to and 
including any follow-up contact. 

All SAEs will be recorded and reported to GSK within 24 hours, as indicated in 
Appendix 4 .

Investigators are not obligated to actively seek AEs or SAEs in former study 
subjects. However, if the investigator learns of any SAE, including a death, at any 
time after a subject has been discharged from the study, and he/she considers the 


2014N218204_03
CONFIDENTIAL
201664
71
event reasonably related to the study treatment or study participation, the investigator 
must promptly notify GSK.
NOTE: The method of recording, evaluating and assessing causality of AEs and SAEs 
plus procedures for completing and transmitting SAE reports to GSK are provided in 
Appendix 4
7.3.1.2.
Method of Detecting AEs and SAEs
Care will be taken not to introduce bias when detecting AEs and/or SAEs. Open-ended 
and non-leading verbal questioning of the subject is the preferred method to inquire about 
AE occurrence.  Appropriate questions include:

“How are you feeling?”

“Have you had any (other) medical problems since your last visit/contact?” 

“Have you taken any new medicines, other than those provided in this study, since 
your last visit/contact?” 
7.3.1.3.
Follow-up of AEs and SAEs
After the initial AE/SAE report, the investigator is required to proactively follow each 
subject at subsequent visits/contacts.  All SAEs, and non-serious AEs of special interest 
(as defined in Section 4.6.1) will be followed until resolution, until the condition 
stabilizes, until the event is otherwise explained, or until the subject is lost to follow-up 
(as defined in Section 5.4). Further information on follow-up procedures is given in 
Appendix 4 .
7.3.1.4.
Regulatory Reporting Requirements for SAEs
Prompt notification by the investigator to GSK of SAEs and non-serious AEs related to 
study treatment (even for non- interventional post-marketing studies) is essential so that 
legal obligations and ethical responsibilities towards the safety of subjects and the safety 
of a product under clinical investigation are met. 
GSK has a legal responsibility to notify both the local regulatory authority and other 
regulatory agencies about the safety of a product under clinical investigation.  GSK will 
comply with country specific regulatory requirements relating to safety reporting to the 
regulatory authority, Institutional Review Board (IRB)/Independent Ethics Committee 
(IEC) and investigators.
Investigator safety reports are prepared for suspected unexpected serious adverse 
reactions according to local regulatory requirements and GSK policy and are forwarded 
to investigators as necessary.
An investigator who receives an investigator safety report describing a SAE(s) or other 
specific safety information (e.g., summary or listing of SAEs) from GSK will file it with 
the IB and will notify the IRB/IEC, if appropriate according to local requirements.

7.3.2.
Pregnancy

Details of all pregnancies in female partners of male subjects will be collected after 
the start of dosing and until follow-up.

If a pregnancy is reported then the investigator should inform GSK within 2 weeks 
of learning of the pregnancy and should follow the procedures outlined in Appendix 
4.
7.3.3.
Physical Exams

A complete physical examination will include, at a minimum, assessment of the 
Cardiovascular, Respiratory, Gastrointestinal and Neurological systems. Height and 
weight will also be measured and recorded. 

A brief physical examination will include, at a minimum assessments of the lungs, 
cardiovascular system, and abdomen (liver and spleen).

Investigators should pay special attention to clinical signs related to previous serious 
illnesses
7.3.4.
Vital Signs

Vital signs will be measured in semi-supine position after 5 minutes rest and will 
include temperature, systolic and diastolic blood pressure and pulse. 

Triplicate readings of blood pressure and pulse rate will be taken and averaged at all 
times.
7.3.5.
Cardiac Monitoring – Electrocardiogram (ECG), Telemetry & Non-
Implantable Devices for Remote Monitoring

12-lead ECGs will be measured in semi-supine position after 5 minutes rest 
(triplicate readings will be taken and averaged at all times) will be obtained at each 
timepoint during the study using an ECG machine that automatically calculates the 
heart rate and measures PR, QRS, QT, and QTcF intervals. Refer to Section 5.4.3 for 
QTcF withdrawal criteria and additional QTcF readings that may be necessary.
7.3.5.1.
Cardiac Safety Monitoring in Cohort 3 (Part B) at Screening & Baseline
This will consist of a 48 hour Holter at Screening and continuous telemetry for 24 hours 
immediately preceding the first dose of GSK303294 at baseline. 

In-Patient Dosing with GSK3039294: Continuous telemetry during repeat 7 day 
dosing of healthy volunteer subjects in Cohort 3 will be performed for up to 
approximately 24 hours after Day 7 to detect any cardiac arrhythmias potentially 
attributable to repeat dosing with GSK3039294 for 7 days in Cohort 3.

CONFIDENTIAL
201664
73
7.3.5.2.
Cardiac Safety Monitoring in Cohort 5 (Part C) patients with known 
cardiac amyloid involvement

Screening: 7-day out-patient cardiac monitoring using an appropriate non-
implantable recording device which is acceptable to the patient – this will 
evaluate the arrhythmic background of eligible cardiac amyloidosis patients such 
that false positive attribution of arrhythmias to GSK3039294 during repeat dosing 
will be minimized.

Baseline: 24 hour in-patient telemetry immediately before the first dose of 
GSK3039294.

In-patient dosing with GSK3039294: Continuous telemetry will be performed 
for up to 24 hours after Day 7 administration of GSK3039294 to detect any 
arrhythmias in patients with known cardiac amyloidosis potentially attributable to 
repeat dosing with GSK3039294 including worsening of known patient-specific 
arrhythmias from Screening and / or Baseline assessments.

Optional cardiac monitoring after completion of in-patient dosing: At 
Investigator discretion, on a case by case basis determined by in-patient cardiac 
telemetry / ECG findings, and in consultation with the Medical Monitor, cardiac 
monitoring can be extended either as an in-patient or as an out-patient (using a 
portable non-implantable device of Investigator choosing) in patients with known 
cardiac amyloidosis.
Cardiac monitoring should continue in cardiac amyloidosis patients based on emerging 
safety data until it is deemed to be clinically appropriate for monitoring to stop after 
consultation with the Medical Monitor.
7.3.6.
Clinical Safety Laboratory Assessments
All protocol required laboratory assessments, as defined in Table 7, must be conducted in 
accordance with the Laboratory Manual, and Protocol Time and Events Schedule.
Laboratory requisition forms must be completed and samples must be clearly labelled 
with the subject number, protocol number, site/centre number, and visit date. Details for 
the preparation and shipment of samples will be provided by the laboratory and are 
detailed in the SRM. Reference ranges for all safety parameters will be provided to the 
site by the laboratory responsible for the assessments.
If additional non-protocol specified laboratory assessments are performed at the 
institution’s local laboratory and result in a change in subject management or are 
considered clinically significant by the investigator (e.g., SAE or AE or dose 
modification) the results must be recorded in the CRF.
Refer to the SRM for appropriate processing and handling of samples to avoid duplicate 
and/or additional blood draws.

7.3.7.
High Sensitivity Cardiac Troponin-T (hs-cTnT) Monitoring after a 
Cardiac Arrhythmia in Part B, or Part C
Baseline hs-cTnT: In Part B  and Part C, all subjects will have hs-cTn level for purposes 
of screening as well as to provide baseline with which to compare, in the event that a 
subject develops a clinically concerning cardiac arrhythmic event after dosing with 
GSK3039294. 
Subjects should be advised by the local study site to abstain from strenuous exercise (e.g. 
running or gym work) ≤ 24 hours before a baseline hs-cTn level is taken.
Monitoring of hs-cTnT after an Arrhythmia Event: A blood samples for hs-cTnT will 
be taken immediately at the time of onset of a cardiac arrhythmia which is deemed by the 
Investigator to be of clinical concern (see Section 5.4.4), or where there is 
electrophysiological diagnostic uncertainty. 
High-sensitivity cTn levels should be serially repeated (using the same assay) following 
local troponin monitoring protocols at the study site, and with advice from a cardiologist 
if this is deemed clinically necessary by the Investigator. 
Additional investigations, including but not restricted to serial ECGs and evaluation of

imaging, can be performed at the discretion of the Investigator in consultation with the 
Medical Monitor and a cardiologist.

Renal Safety Monitoring
All urine studies will be performed in the early morning prior to eating in healthy 
volunteers (with the expection of the Part B, Day 4 which will be fasting) and patients. 
For all Parts of the study, a urine sample will be taken and stored from individual subjects 
at baseline for each dose level in Part A, at the beginning of week 1 for repeat dosing in 
Parts B & C, and at the beginning of week 2 in Part B only (see T&E Table).
Core renal parameters will assessed frequently as shown in the T&E Tables.

Whenever urine pH is 
confirmed to be < 6.0 on an 
average of three readings over 
10 minutes from the same 
urine sample additional 
assesments e.g. a venous 
bicarbonate analysis will be 
initially performed. If this is 
deemed to be low, an arterial 
blood gas (ABG) must then be 
performed to investigate 
development of metabolic 
acidosis.
7.3.8.1.
Guidance on the Clinical Approach for Suspected Renal Injury
If Renal Injury is Suspected (any subject), additional urine samples will be taken on a 
prospective basis if biochemical signatures of renal injury are detected at any time during 
the study. Urine samples will be analysed for biomarkers of renal injury (e.g. KIM-1 and 
NGAL), as well as for the presence of small molecular proteins (e.g. cystatin C & α1-
microglobulin). The Investigator should liaise with a local nephrologist as regards any 
additional investigations which may be necessary to confirm either that renal injury has 
occurred or its nature.

Genetics
In the event of an unexpected PK profile (i.e. increased or decreased metabolism of 
GSK3039294) being observed in an individual subject during any Part of the study, 
germline SNP analysis for recognised esterase-encoded genes which have been 
previously implicated in the dysfunctional metabolism of other esterase-cleaved 
prodrugs (e.g. CES-1 in oseltamivir), or genome-wide locus agnostic analysis, will 
be initiated from the stored blood samples of the affected individual subject(s). In 
addition, the stored blood samples of the remaining unaffected subjects within that 
particular part of the study will also undergo SNP analysis. This will facilitate 
comparative SNP data analysis of the affected subject(s) versus the rest of the study 
population.
Information regarding genetic research will be included in Appendix 3.
8.
DATA MANAGEMENT

No formal hypotheses will be tested in this study.

Sample Size Considerations
9.2.1.
Sample Size Assumptions
The sample size for this study is based primarily on feasibility.  An assessment of the 
planned sample size has been based on the level of precision the study would provide

81
around the estimated true rate of a given safety event and around the estimated SAP 
depletion levels for a given dose. 
9.2.1.1.
Safety
Table 11 presents the 95% credible interval for the true event rate of a specific AE, 
assuming various observed AE rates and a sample size of 6 and 12. Here the credible 
interval specifies with a fixed probability of 95%, a range of values for the true AE rate 
after updating some prior position on the true AE rate with the AE data observed during 
the study. In general, a larger sample size will yield a narrower 95% credible interval.
For example, if we observe one specific adverse event in a single cohort/dosing session 
with n=6, ie an observed AE rate of 17%, then there is a 95% probability that the true AE 
rate lies between 4 and 58%. This implies that a true AE rate of greater than 58% could 
occur, though with a 2.5% probability.
Similarly, if we observe one specific adverse event in a single cohort/dosing session with 
n=12, ie an observed AE rate of 8%, then there is a 95% probability that the true AE rate 
lies between 2 and 36%. This implies that a true AE rate of greater than 36% could occur, 
though with a 2.5% probability.

9.2.1.2.
Pharmacodynamics (Plasma SAP)
The standard deviation of log-transformed post-dose plasma SAP depletion levels, based 
on completed CPHPC studies to date, is assumed to be approximately 0.3 in healthy 
volunteers and between 0.7 and 0.9 in systemic amyloidosis patients.  
With an assumed standard deviation of 0.9 for log-transformed post-dose plasma SAP 
depletion levels, and 6 subjects, the upper limit of the 95% confidence interval (CI) 
around the observed geometric mean post-dose plasma SAP level will be 2.57 times the 
observed geometric mean. Hence, if we observe a geometric mean post-dose plasma SAP 
level of 2mg/L, then the upper limit of the 95% CI around this observed geometric mean 


2014N218204_03

82
will be approximately 5.1mg/L.  Similarly, if we observe a geometric mean post-dose 
plasma SAP level of 0.5mg/L, then the upper limit of the 95% CI around this observed 
geometric mean will be approximately 1.3mg/L.  
A small gain in precision is achieved with more than 6 subjects (see Section 9.2.2, 
Sample Size Sensitivity).
9.2.2.
Sample Size Sensitivity
An assessment of sample size sensitivity has been based on the level of precision the 
study would provide around the estimated true rate of a given safety event and around the 
estimated SAP depletion levels for a given dose.
9.2.2.1.
Safety
Table 12 presents the 95% credible interval for the true event rate of a given AE, 
assuming various observed AE rates and selected sample sizes between 5 and 20.  
Sample sizes of less than 6 per cohort/dosing session were not planned since this would 
mean, irrespective of the number of events for a given AE in a single cohort/dosing 
session (i.e. an observed AE rate of ≥0%) that the upper limit of the 95% credible interval 
for the true AE rate would range as high as approximately 50% or more.
Sample sizes greater than 12 per cohort/dosing session were not planned since in order to 
provide significant gains in terms of safety information, the sample size would need to be 
increased beyond feasibility.  For example, with a sample size of 20, if we observe one 
given adverse event (ie an observed AE rate of 5%) then a 95% credible interval about 
the true AE rate would still have an upper limit as high as 24%.

Pharmacodynamics (Plasma SAP)
Figure 5 shows how the precision around the observed geometric mean post-dose plasma 
SAP levels improves with decreasing standard deviation and increasing sample size (i.e. 
the factor by which the upper 95% CI is above the observed geometric mean decreases 
with decreasing standard deviation and increasing sample size). 
Given an expected post-dose depletion level for plasma SAP to less than 2mg/L, no 
significant improvement in precision would be achieved with greater than 6 subjects.  
Similarly, precision levels across the explored range of standard deviations would not 
differ significantly.

Safety Population:
This population is defined as all subjects who received at least one dose of study 
medication.  This will be the primary population for assessing safety.

CONFIDENTIAL
201664
85
PK Population:
This population is defined as all subjects administered at least one dose of study 
medication and who have at least one PK sample taken and analysed.  This will be the 
primary population for assessing PK.  Subjects will be classified by the actual dose 
received.
PD Population:
This population is defined as all subjects who received at least one dose of study 
medication and who also have a baseline measurement and at least one post-treatment PD 
measure. This will be the primary population for assessing PD.  Subjects will be 
classified by the actual dose received.
PK/PD Population:
This population is defined as all subjects included in both the PK and PD populations.  
This will be the primary population for PK/PD modelling.  Subjects will be classified by 
the actual dose received.
9.3.2.
Interim Analysis
Data will be reviewed on an ongoing basis throughout the study by the study team and 
investigator in order to inform dosing decisions for subsequent dosing sessions, cohorts 
and study parts.  Dose escalation meetings will be held prior to increasing the dose. Key 
data to inform dosing decisions will include but not be limited to: safety (AEs, clinical 
laboratory data, vital signs and ECGs), PK (concentrations of GSK2315698, and if 
possible, GSK3039294 and the intermediate molecule GSK3037412), and plasma SAP 
levels (Parts B & C only).
In addition to the ongoing review of data throughout the study, at the end of Part B,
individual profiles over time will be presented graphically for selected urine and plasma 
laboratory parameters pertaining to the kidney. Individual profiles will be presented for 
both single and repeat-dose healthy volunteer data to further inform the evaluation of 
renal safety and the decision to progress to repeat dosing in systemic amyloidosis patients 
in Part C.
9.3.2.1.
Pharmacokinetics and pharmacodynamics
To inform dosing decisions for subsequent dosing sessions in Part A, individual values of 
Cmax and AUC[0-inf] will be derived by means of non-compartmental analysis. 
Assuming linear kinetics, the next dose will be such that the 95%CI of Cmax and AUC 
will not exceed preclinical safety limits (22.1 g /mL and 250 g.hr/mL, respectively).
To inform dosing decisions for subsequent study parts, GSK2315698 concentration data 
and plasma SAP levels will be analysed using the PK/PD model that was developed for 
GSK2315698 [Sahota, 2015]. Based on pre-clinical data it is expected that the 
conversion of GSK3039294 to GSK2315698 is very fast. Therefore, it can be assumed 
that this conversion will occur mainly during the absorption phase, and that the 


2014N218204_03
CONFIDENTIAL
201664
86
distribution and elimination of GSK2315968 are not altered. Therefore, all distribution 
and elimination parameters (PK/PD) will be fixed to the reported parameter estimates, 
and only bioavailability (F) and absorption related parameters (e.g. Ka) will be estimated. 
Nominal time points will be used for this interim analysis. This updated model will be 
used to simulate concentration-time data and plasma SAP levels using different dose 
levels and dosing regimens, which will be used to inform dosing decisions for subsequent 
dosing sessions, cohorts and study parts.
9.4.
Key Elements of Analysis Plan
9.4.1.
Primary Analyses
Safety data will be listed and presented in tabular and/or graphical format, as appropriate, 
and summarized descriptively according to GSK’s Integrated Data Standards Library 
(IDSL) standards.
9.4.2.
Secondary Analyses
9.4.2.1.
Pharmacokinetics, pharmacodynamics and PK/PD model
Concentration data of GSK2315698 and GSK3039294 will be listed and presented in 
tabular and graphical format, as appropriate, and summarised descriptively. Further 
details will be described in the RAP.
Individual plasma SAP profiles over time will be listed and presented graphically.  
Plasma SAP levels will be log-transformed, or other transformation as appropriate, and 
summarised over time by cohort/dose, together with corresponding 95% confidence 
intervals.  Further details will be described in the RAP.
GSK2315698 concentration data and plasma SAP levels will be analysed using the 
PK/PD model that was developed for GSK2315698 [Sahota, 2015]. Based on pre-
clinical data it is expected that the conversion of GSK3039294 to GSK2315698 is very 
fast. Therefore, it can be assumed that this conversion will occur mainly during the 
absorption phase, and that the distribution and elimination of GSK2315698 are not 
altered. GSK3039294 and the intermediate molecule GSK3037412 do not affect plasma 
SAP levels, and therefore it can be assumed that the PK/PD relationship between 
GSK2315698 and SAP is not changed. Therefore, all distribution and elimination 
parameters and all PD parameters will be fixed to the reported parameter estimates, and 
only bioavailability (F) and absorption related parameters (e.g. Ka) will be estimated. If 
needed, the PK/PD model may be updated in a data driven fashion. Actual time points 
will be used for this final analysis. Further details will be described in the RAP.

institution (where applicable) must inform the IRB/IEC promptly and provide the 
reason for the suspension or premature discontinuation.
10.6.
Records Retention

Following closure of the study, the investigator or the head of the medical institution 
(where applicable) must maintain all site study records (except for those required by 
local regulations to be maintained elsewhere), in a safe and secure location.  

The records must be maintained to allow easy and timely retrieval, when needed 
(e.g., for a GSK audit or regulatory inspection) and must be available for review in 
conjunction with assessment of the facility, supporting systems, and relevant site 
staff.  

Where permitted by local laws/regulations or institutional policy, some or all of these 
records can be maintained in a format other than hard copy (e.g., microfiche, 
scanned, electronic); however, caution needs to be exercised before such action is 
taken.  

The investigator must ensure that all reproductions are legible and are a true and 
accurate copy of the original and meet accessibility and retrieval standards, including 
re-generating a hard copy, if required.  Furthermore, the investigator must ensure 
there is an acceptable back-up of these reproductions and that an acceptable quality 
control process exists for making these reproductions.

GSK will inform the investigator of the time period for retaining these records to 
comply with all applicable regulatory requirements.  The minimum retention time 
will meet the strictest standard applicable to that site for the study, as dictated by any 
institutional requirements or local laws or regulations, GSK standards/procedures, 
and/or institutional requirements.  

The investigator must notify GSK of any changes in the archival arrangements, 
including, but not limited to, archival at an off-site facility or transfer of ownership 
of the records in the event the investigator is no longer associated with the site.
10.7.
Provision of Study Results to Investigators, Posting of 
Information on Publically Available Clinical Trials Registers 
and Publication
Where required by applicable regulatory requirements, an investigator signatory will be 
identified for the approval of the clinical study report.  The investigator will be provided 
reasonable access to statistical tables, figures, and relevant reports and will have the 
opportunity to review the complete study results at a GSK site or other mutually-
agreeable location.
GSK will also provide the investigator with the full summary of the study results.  The 
investigator is encouraged to share the summary results with the study subjects, as 
appropriate.

Appendix 3 - Genetic Investigation of Individuals
Genetic Research Objectives and Analyses
The objectives of the genetic research are to investigate the relationship between genetic 
variants and: 

Response to any treatment regimens under investigation in this study
Genetic data may be generated while the study is underway or following completion of 
the study.  Single Nucleotide Polymorphism (SNP) analysis for recognised esterase-
encoded genes which have been previously implicated in the dysfunctional metabolism of 
other esterase-cleaved prodrugs (e.g. CES-1 in oseltamivir), or genome-wide locus 
agnostic analysis, may be performed to investigate (for example) an unexpected PK or 
plasma SAP profile, and / or clinically concerning AEs being observed in an individual 
subject. Genetic analyses will utilize data collected in the study and will be limited to 
understanding the objectives highlighted above.  Analyses may be performed using data 
from multiple clinical studies to investigate these research objectives.
Appropriate descriptive and/or statistical analysis methods will be used. A detailed 
description of any planned analyses will be documented in a Reporting and Analysis Plan 
(RAP) prior to initiation of the analysis. Planned analyses and results of genetic 
investigations will be reported either as part of the clinical RAP and study report, or in a 
separate genetics RAP and report, as appropriate.
Study Population
Any subject who is enrolled in the study can participate in genetic research.  Any subject 
who has received an allogeneic bone marrow transplant must be excluded from the 
genetic research.
Study Assessments and Procedures
A key component of successful genetic research is the collection of samples during 
clinical studies.  

A 6 ml blood sample will be taken for Deoxyribonucleic acid (DNA) extraction. A 
Blood sample is collected during the study, after the subject has been randomized 
and provided informed consent for genetic research. Instructions for collection and 
shipping of the genetic sample are described in the laboratory manual. The DNA 
from the blood/saliva sample may undergo quality control analyses to confirm the 
integrity of the sample. If there are concerns regarding the quality of the sample, then 
the sample may be destroyed. The blood/saliva sample is taken on a single occasion 
unless a duplicate sample is required due to an inability to utilize the original sample.  
The genetic sample is labelled (or “coded”) with the same study specific number used to 
label other samples and data in the study.   This number can be traced or linked back to 
the subject by the investigator or site staff. Coded samples do not carry personal 
identifiers (such as name or National Insuramnce number). 


2014N218204_03
CONFIDENTIAL
201664
100
Samples will be stored securely and may be kept for up to 15 years after the last subject 
completes the study, or GSK may destroy the samples sooner.  GSK or those working 
with GSK (for example, other researchers) will only use samples collected from the study 
for the purpose stated in this protocol and in the informed consent form.  Samples may be 
used as part of the development of a companion diagnostic to support the GSK medicinal 
product.
Subjects can request their sample to be destroyed at any time.
Informed Consent
Subjects who do not wish to participate in the genetic research may still participate in the 
study.  Genetic informed consent must be obtained prior to any blood/saliva being taken.
Subject Withdrawal from Study
If a subject who has consented to participate in genetic research withdraws from the 
clinical study for any reason other than being lost to follow-up, the subject will be given a 
choice of one of the following options concerning the genetic sample, if already 
collected:

Continue to participate in the genetic research in which case the genetic DNA sample 
is retained

Discontinue participation in the genetic research and destroy the genetic DNA 
sample 
If a subject withdraws consent for genetic research or requests sample destruction for any 
reason, the investigator must complete the appropriate documentation to request sample 
destruction within the timeframe specified by GSK and maintain the documentation in 
the site study records. 
Genotype data may be generated during the study or after completion of the study and 
may be analyzed during the study or stored for future analysis. 

If a subject withdraws consent for genetic research and genotype data has not been 
analyzed, it will not be analyzed or used for future research.  

Genetic data that has been analyzed at the time of withdrawn consent will continue 
to be stored and used, as appropriate. 
Screen and Baseline Failures
If a sample for genetic research has been collected and it is determined that the subject

instruct the subject that their genetic sample will be destroyed. No forms are required to 
complete this process as it will be completed as part of the consent and sample 
reconciliation process.  In this instance a sample destruction form will not be available to

Provision of Study Results and Confidentiality of Subject’s Genetic Data
GSK may summarize the genetic research results in the clinical study report, or 
separately and may publish the results in scientific journals. 
GSK may share genetic research data with other scientists to further scientific 
understanding in alignment with the informed consent. GSK does not inform the subject, 
family members, insurers, or employers of individual genotyping results that are not 
known to be relevant to the subject’s medical care at the time of the study, unless
required by law. This is due to the fact that the information generated from genetic 
studies is generally preliminary in nature, and therefore the significance and scientific 
validity of the results are undetermined.  Further, data generated in a research laboratory 
may not meet regulatory requirements for inclusion in clinical care.

Appendix 4: Definition of and Procedures for Recording, 
Evaluating, Follow-Up and Reporting of Adverse Events
12.4.1.
Definition of Adverse Events
Adverse Event Definition:

An AE is any untoward medical occurrence in a patient or clinical investigation 
subject, temporally associated with the use of a medicinal product, whether or not 
considered related to the medicinal product.

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 medicinal product.
Events meeting AE definition include:

Any abnormal laboratory test results (hematology, clinical chemistry, or urinalysis) 
or other safety assessments (e.g., ECGs, radiological scans, vital signs 
measurements), including those that worsen from baseline, and felt to be clinically 
significant in the medical and scientific judgement of the investigator.

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 prior to the start of the study.

Signs, symptoms, or the clinical sequelae of a suspected 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 this is an intentional overdose taken with possible suicidal/self-
harming intent.  This should be reported regardless of sequelae).
.
Events NOT meeting definition of an AE include:

Any clinically significant abnormal laboratory findings or other abnormal safety 
assessments which are associated with the underlying disease, unless judged by the 
investigator to be more severe than expected for the subject’s condition.

The disease/disorder being studied or expected progression, signs, or symptoms of 
the disease/disorder being studied, unless more severe than expected for the subject’s 
condition.

Medical or surgical procedure (e.g., endoscopy, appendectomy): the condition that 
leads to the procedure is an AE.


2014N218204_03
CONFIDENTIAL
201664
103

Situations where 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.
12.4.2.
Definition of Serious Adverse Events
If an event is not an AE per definition above, then it cannot be an SAE even if serious 
conditions are met (e.g., hospitalization for signs/symptoms of the disease under study, 
death due to progression of disease, etc).
Serious Adverse Event (SAE) is defined as any untoward medical occurrence that, 
at any dose:
a. Results in death
b. Is life-threatening
NOTE:
The term 'life-threatening' in the definition of 'serious' refers to an event in which the 
subject was at risk of death at the time of the event.  It does not refer to an event, which 
hypothetically might have caused death, if it were more severe.
c.
Requires hospitalization or prolongation of existing hospitalization
NOTE:

In general, hospitalization signifies that the subject has been detained (usually 
involving at least an overnight stay) at the hospital or emergency ward for 
observation and/or treatment that would not have been appropriate in the physician’s 
office or out-patient setting.  Complications that occur during hospitalization are 
AEs.  If a complication prolongs hospitalization or fulfills any other serious criteria, 
the event is serious.  When in doubt as to whether “hospitalization” occurred or was 
necessary, the AE should be considered serious.

Hospitalization for elective treatment of a pre-existing condition that did not worsen 
from baseline is not considered an AE.
d.
Results in disability/incapacity
NOTE:

The term disability means a substantial disruption of a person’s ability to conduct 
normal life functions.

This definition is not intended to include experiences of relatively minor medical 
significance such as uncomplicated headache, nausea, vomiting, diarrhea, influenza, 
and accidental trauma (e.g. sprained ankle) which may interfere or prevent everyday 
life functions but do not constitute a substantial disruption


2014N218204_03
CONFIDENTIAL
201664
104
e.
Is a congenital anomaly/birth defect
f.
Other situations:

Medical or scientific judgment should be exercised in deciding whether reporting is 
appropriate in other situations, such as important medical events that may not be 
immediately life-threatening or result in death or hospitalization but may jeopardize 
the subject or may require medical or surgical intervention to prevent one of the 
other outcomes listed in the above definition.  These should also be considered 
serious.

Examples of such events are 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
g.
Is associated with liver injury and impaired liver function defined as:

ALT 3xULN and total bilirubin* 2xULN (>35% direct), or

ALT 3xULN and INR** > 1.5.
* Serum bilirubin fractionation should be performed if testing is available; if unavailable, 
measure urinary bilirubin via dipstick.  If fractionation is unavailable and ALT 3xULN 
and total bilirubin 2xULN, then the event is still to be reported as an SAE.
** INR testing not required per protocol and the threshold value does not apply to 
subjects receiving anticoagulants.  If INR measurement is obtained, the value is to be 
recorded on the SAE form.

Refer to Appendix 2 for the required liver chemistry follow-up instructions
12.4.3.
Recording of AEs and SAEs
AEs and SAE Recording:

When an AE/SAE occurs, it is the responsibility of the investigator to review all 
documentation (e.g., hospital progress notes, laboratory, and diagnostics reports) 
relative to the event.

The investigator will then record all relevant information regarding an AE/SAE in 
the CRF

It is not acceptable for the investigator to send photocopies of the subject’s medical 
records to GSK in lieu of completion of the GSK, AE/SAE CRF page.

There may be instances when copies of medical records for certain cases are 
requested by GSK.  In this instance, all subject identifiers, with the exception of the 
subject number, will be blinded on the copies of the medical records prior to 
submission of to GSK.

The investigator will attempt to establish a diagnosis of the event based on signs, 


2014N218204_03
CONFIDENTIAL
201664
105
symptoms, and/or other clinical information.  In such cases, the diagnosis will be 
documented as the AE/SAE and not the individual signs/symptoms.
12.4.4.
Evaluating AEs and SAEs
Assessment of Intensity
The investigator will make an assessment of intensity for each AE and SAE reported 
during the study and will assign it to one of the following categories:

Mild:  An event that is easily tolerated by the subject, causing minimal discomfort 
and not interfering with everyday activities.

Moderate:  An event that is sufficiently discomforting to interfere with normal 
everyday activities

Severe:  An event that prevents normal everyday activities. - an AE that is assessed 
as severe will not be confused with an SAE. Severity is a category utilized for rating 
the intensity of an event; and both AEs and SAEs can be assessed as severe.

An event is defined as ‘serious’ when it meets at least one of the pre-defined 
outcomes as described in the definition of an SAE.
Assessment of Causality

The investigator is obligated to assess the relationship between study treatment and 
the occurrence of each AE/SAE.

A "reasonable possibility" is meant to convey that there are facts/evidence 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 natural history of the underlying diseases, concomitant 
therapy, other risk factors, and the temporal relationship of the event to the study 
treatment will be considered and investigated.

The investigator will also consult the Investigator Brochure (IB) and/or Product 
Information, for marketed products, in the determination of 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 when 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 
prior to the initial transmission of the SAE data to GSK.

The investigator may change his/her opinion of causality in light of follow-up 


2014N218204_03
CONFIDENTIAL
201664
106
information, amending the SAE data collection tool accordingly.

The causality assessment is one of the criteria used when determining regulatory 
reporting requirements.
Follow-up of AEs and SAEs

The investigator is obligated to perform or arrange for the conduct of supplemental 
measurements and/or evaluations as may be indicated or as requested by GSK to 
elucidate as fully as possible the nature and/or causality of the AE or SAE.

The investigator is obligated to assist.  This may include additional laboratory tests 
or investigations, histopathological examinations or consultation with other health 
care professionals.

If a subject dies during participation in the study or during a recognized follow-up 
period, the investigator will provide GSK with a copy of any post-mortem findings, 
including histopathology.

New or updated information will be recorded in the originally completed CRF.

The investigator will submit any updated SAE data to GSK within the designated 
reporting time frames.
12.4.5.
Reporting of SAEs to GSK
SAE reporting to GSK via paper CRF

Facsimile transmission of the SAE paper CRF is the preferred method to transmit 
this information to the Medical Monitor 

In rare circumstances and in the absence of facsimile equipment, notification by 
telephone is acceptable, with a copy of the SAE data collection tool sent by 
overnight mail

Initial notification via the 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 receipt can be found at this beginning of the protocol on the 
Sponsor/Medical Monitor Contact Information page.

The maximum duration of 21 days for Part B was selected to reflect the likely duration of 
treatment needed for clinical use with the anti SAP monoclonal antibody. The duration of 
7 days treatment before dose escalation was chosen as, based on the half life of CPHPC 
of approximately 18 hrs, steady state PK will be achieved by 4 days.

The duration of 7 days for Cohort 3 Part B was selected as steady state is predicted 
to be achieved in this time. The maximum duration of 21 days for Cohorts 4a and 4b 
in Part B was selected to reflect the likely duration of treatment needed for clinical use 
with the anti SAP monoclonal antibody. The duration of 7 days treatment before dose 
escalation was chosen as, based on the half life of CPHPC of approximately 18 hrs, 
steady state PK will be achieved by 4 days.

Part B
The dose level in Part B will be determined based on the PK data obtained in Part A, by 
analysing all available PK data from Part A and subsequently predicting concentration-
time profiles at steady state after repeat dosing (see Section 9.3.2.1). The dose levels and 
dosing frequencies will be chosen such that the predicted 95% CI of Cmax and AUC at 
steady state will not exceed preclinical Cmax and AUC limits (22.1 g/mL and 
250 g.hr/mL, respectively).
REVISED TEXT
Part B
The dose level for Cohort 3 in Part B will be determined based on the PK data obtained 
in Part A, by analysing all available PK data from Part A and subsequently predicting 
concentration-time profiles at steady state after repeat dosing. Table 3 shows examples 
of dose levels and frequencies with predicted AUC[0-24] and Cmax at steady state, 
using the PK/PD model that was developed for CPHPC (active molecule) [Sahota, 
2015], adjusted for oral absorption and conversion of GSK3039294 into CPHPC. 
The PK data from Part A will be used to obtain estimates for Ka and F.

The dose levels for subsequent cohorts in Part B will be determined based on the PK 
data from Part A (single dose), and cohort 3 in Part B (multiple dose). All available 
PK data will be analysed (see Section 9.3.2.1). The dose levels and dosing frequencies

Part B: Repeat dose escalation in healthy volunteers
Cohort 3: In a group of healthy volunteers sufficient subjects will be enrolled to ensure 6 
completers, the study drug will be administered repeatedly for a total of 7 days.  The dose 
will be one that is expected to be well tolerated based on the single dose data and not 
predicted to exceed exposure limits based on single dose PK. Providing a review of the 
data (safety data: AE, vital signs, ECG, laboratory safety tests and PK) is favourable, 
Cohort 4 will be initiated.
A food effect exploration will be conducted at Days 4 and 5 of this cohort. On these days 
GSK3039294 will be administered under fasted and then under fed conditions

Part B: Repeat dose escalation in healthy volunteers
Cohort 3: In a group of healthy volunteers (preferably < 45 years of age) sufficient 
subjects will be enrolled to ensure 6 completers, the study drug will be administered 
repeatedly for a total of 7 days.  The dose will be one that is expected to be well tolerated 
based on the single dose data and not predicted to exceed exposure limits based on single 
dose PK. Providing a review of the data (safety data: AE, vital signs, ECG, laboratory 
safety tests and PK) is favourable, Cohort 4 will be initiated.
A food effect exploration will be conducted at Days 4 and 5 of this cohort. On these days 
GSK3039294 will be administered under fasted and then under fed conditions
A sentinel subject will be dosed first with repeat GSK3039294 administration for 7 
consecutive days. Subsequent subjects will only be dosed after the sentinel subject 
has successfully completed the full 7 days of dosing without any clinically 
concerning AEs being reported. If the safety data from the sentinel subject is 
deemed to be equivocal, a second subject can be dosed individually for 7 days at the 
discretion of the Investigator in consultation with the GSK study team. If the safety 
data from the second subject is also equivocal, at the discretion of the Investigator in 
consultation with the GSK study team, subsequent subjects can also be individually 
dosed with GSK3039294 for 7 days. 
The food effect exploration in Cohort 3 will only be conducted once the Investigator 
in consultation with the GSK study team is satisfied with the safety profile of repeat 
dose GSK3039294. Following this, the food effect will be conducted on Days 4 and 5, 
and GSK3039294 will be administered under fasted and then under fed conditions 
(respectively).
Sufficient subjects will be enrolled to ensure a minimum of 6 subjects complete all 
study procedures, including the food effect exploration.
Providing a review of the data (safety data: AE, vital signs, ECG, telemetry, 
laboratory safety tests and PK) is overall acceptable, Cohort 4a will be initiated. The 
approving REC will be informed of the outcome of this data review.

Cohort Safety Reviews: A safety review will be performed on completion of each 
Cohort in Part B, as well as at completion of Cohort 5 in Part C (see Section 4.2.2. & 
Section 4.2.3.). Initiation of Cohort 4a will be contingent on the findings of the safety 
review at completion of Cohort 3 (see Section 4.2.2.)
Summary of Cardiac Arrhythmia Adverse Events in Part A of this study
A total of 4 separate arrhythmias in 3 male subjects over 45 year old were reported 
on 24-hour Holter after single dose administration of GSK3039294 in Part A. Three 
episodes of supraventricular tachycardia (SVT), all of atrial tachycardia 
morphology at doses of GSK3039294 at 600mg and 1200mg, and one episode of a 
single 5-beat accelerated idioventricular rhythm (AIVR) at 600mg GSK3039294, 
were reported in these 3 separate subjects. Each of the events was of short duration, 
completely asymptomatic, and was not associated with hemodynamic instability. 
No prolongation of the QTcF interval was observed in any subject after 
administration of 200mg, 600mg, or 1200mg of GSK3039294 in Part A.

132
Both SVTs and ventricular salvos of short duration are known to occur in healthy 
volunteer subjects and can be considered to be within the normal (non-pathological) 
variation of ECG parameters. In this regard, SVTs have been reported to arise in 
13.9% of healthy volunteer subjects over 45 years of age compared to an incidence 
of 1.1% in healthy volunteer subjects 45 years or less in FIH studies (Hingorani et 
al, 2016). In Part A, none of the three affected subjects had plasma levels of 
GSK3039294 detectable approximate to the time at which each cardiac arrhythmia 
occurred. Moreover, the timing of each of the four arrhythmic events after dosing 
with GSK3039294 was not associated with the Tmax of CPHPC including one 
subject whom had no detectable plasma CPHPC present at approximately the time 
of the first of their two arrhythmic events.
Therefore, at this time, given that there were also no arrhythmogenic liabilities 
identified for GSK3039294 in preclinical toxicological studies, it is unlikely that the 
arrhythmias reported after dosing with GSK3039294 in Part A are attributable to 
its single dose administration at 600 mg or 1200mg.

PREVIOUS TEXT
Part B is repeat dose, open label, dose escalation conducted in healthy volunteer subjects
and will evaluate the safety, tolerability, PK, pharmacodynamics of repeat dosing of 
GSK3039294. In addition to PK, plasma SAP levels will be measured at time points as in 
the Time and Events table (Section 7.1.1) to determine the ability of GSK3039294 to 
decrease plasma SAP levels to aid prediction of the optimal clinical dose.
In a group of healthy volunteers sufficient subjects will be enrolled to ensure a minimum 
of 6 subjects complete all study procedures (including the food-effect part) completers, 
the study drug will be administered repeatedly for a total of 7 days.  The dose will be one 
that is expected to be well tolerated based on the single dose data and predicted to not 
exceed exposure limits based on single dose PK. Providing a review of the data (safety

data: AE, vital signs, ECG, laboratory safety tests and PK) is favourable, Cohort 4 will be 
initiated.
Sentinel dosing:  The subsequent subjects will be dosed after the first subject has 
completed all dosing days if there are no safety or tolerability concerns.
A food effect exploration will be conducted at Days 4 and 5 of this cohort. On these days
GSK3039294 will be administered under fasted and then under fed conditions (please see 
SRM for details of meals), and PK samples will be taken to investigate the food effect on 
the PK.
In a group of healthy volunteers sufficient subjects will be enrolled to ensure 6 
completers, the study drug will be administered repeatedly for a total of 21 days. 
The dose level for this cohort will be determined by a review of the safety and PK data 
from cohort 3. The dose may be adjusted (up or down) during the 21 day dosing session 
based on preliminary PK collected during dosing and ongoing review of safety. If the 
dose is to be altered, this will be done no later than Day 16 in order to achieve a new 
steady-state at Day 21.
The predicted maximum daily exposure dose that will not exceed pre-clinical safety 
exposure limits.
Data from cohorts 3 and 4a are expected to provide a good evaluation of the safety, 
tolerability and repeat-dose PK. The data will be evaluated using the PK/PD model to 
identify an optimal clinical dose (see Section 9.3.2.1). However, if it is determined that 
further investigation of dose levels are required before progressing to Part C (e.g. if the 
observations in cohort 4a are different from those which the PK /PD modelling 
predicted), then recruitment into Cohort 4b may be initiated.
Based on data from Cohorts 3 and 4a, dose levels will be selected for further 
investigation in a further cohort of healthy volunteers (recruitment to ensure 6
completers). For this purpose the compound will be dosed for 21 consecutive days. The 
dose level and / or dosing regimen may be altered once during the 21 days providing a 
review of the data from the starting dose (safety data: AE, vital signs, ECG, laboratory 
safety tests and PK – all obtained once steady state has been achieved) is favourable. The 
predicted maximum daily dose administered will not exceed pre-clinical safety exposure 
limits.

Sentinel Dosing in Part B
In each individual study cohort in Part B, a sentinel subject will complete all dosing 
days up to and including Day 7. If there are no clinically concerning safety or 
tolerability issues observed, the rest of the subjects within the cohort can be dosed. 
If the safety data from the sentinel subject is deemed to be equivocal, a second (and 
subsequent) subjects will complete all dosing days individually, up to and including 
Day 7, at the discretion of the Investigator in consultation with the GSK study team.

a potential food effect, On these days GSK3039294 will be administered under fasted 
and then under fed conditions (please see SRM for details of meals), and PK samples will 
be taken to investigate the food effect on the PK.
Cardiac Safety Review of Cohort 3
Given that all cardiac arrhythmic events after single dose administration of 
GSK3039294 in Part A (where there were detectable levels of plasma CPHPC) were 
relatively acute and observed between approximately 4 to 7 hours after tmax of 
CPHPC and when no GSK3039294 was detectable, and given steady state is 
expected to be reached after approximately 5 days of repeat dosing, 7 day 
continuous cardiac telemetry in Cohort 3 is deemed to be of sufficient duration to 
detect any potential cardiac arrhythmias associated with repeat dosing of 
GSK3039294. 
On completion, in addition to full safety review, a cardiac safety review will be 
performed where individual subject telemetry data will be reviewed in relation to 
the PK data of GSK3039294 and CPHPC.
21 Day Repeat Dosing (Cohort 4a)
In a group of healthy volunteers sufficient subjects will be enrolled to ensure 6 
completers, the study drug will be administered repeatedly for a total of 21 days. 
The dose level for this cohort will be determined by a review of the safety and PK data
from cohort 3. The dose may be adjusted (up or down) during the 21 day dosing session

Initiation of Cohort 4a: Cohort 4a will only be initiated if the conclusion of the 
safety review from Cohort 3 demonstrates an acceptable safety profile associated 
with the repeat administration of GSK3039294 for 7 days. 
Individual subjects in Cohort 4a can be withdrawn from the study at the discretion 
of the Investigator in consultation with the GSK study team if individual subject 
safety review at Day 7 demonstrates any AEs which are deemed to be equivocal or 
clinically concerning. Affected subject(s) should be followed-up, at the discretion of 
the Investigator, as per local practice.
Data from cohorts 3 and 4a are expected to provide a good evaluation of the safety, 
tolerability and repeat-dose PK. The data will be evaluated using the PK/PD model to 
identify an optimal clinical dose (see Section 9.3.2.1). However, if it is determined that

Section 4.6.3. Overall Benefit:Risk Conclusion
PREVIOUS TEXT
GSK3039294 is an oral prodrug of CPHPC, as such it is expected to release CPHPC after 
oral administration. Previous clinical experience with CPHPC shows it has a good safety 
and tolerability profile therefore we do not anticipate safety issues linked to the release of 
the active moiety.
Biotransformation from prodrug into active will release 2 molecules of formaldehyde. 
There is precedent of drugs releasing formaldehyde with no associated toxicity.
Preclinical signs of potential nephrotoxicity were observed at very high doses which are 
unlikely to be reached in the clinic, however monitoring of renal function will be 
performed in the study in order to detect any potential changes. 
There will be no medical benefit to healthy volunteers or patients with systemic 
amyloidosis being treated with GSK3039294 alone. The design of the study, schedule of 
assessments, and oversight mean that any risks to participants are minimised including 
those which might potentially affect the kidney, and therefore the clinical study is 
justified.

and tolerability profile therefore we do not anticipate safety issues linked to the release of 
the active moiety.
At this time, although the cardiac arrhythmias reported in Part A are unlikely to be 
attributable to single dose administration of GSK3039294 at either 600mg or 
1200mg, as a precaution, and to further assess and confirm this conclusion, the 
cardiac safety monitoring of healthy volunteer subjects during repeat dose 
administration of GSK3039294 for 7 consecutive days in Cohort 3 Part B has been 
enhanced (see Section 7.3.7.), and also in systemic amyloidosis patients in Cohort 5 
Part C who are known to have cardiac amyloid involvement (see Section 7.3.8.).
Biotransformation from prodrug into active will release 2 molecules of formaldehyde. 
There is precedent of licensed prodrugs drugs releasing formaldehyde with no 
associated toxicity on a background that formaldehyde is physiologically metabolised 
very rapidly within the systemic circulation (EFSA Journal, 2014; 12(2):3550).
Preclinical signs of potential nephrotoxicity were observed at very high doses which are 
unlikely to be reached in the clinic, however monitoring of renal function will be 
performed in the study in order to detect any potential changes. 
There will be no medical benefit to healthy volunteers or patients with systemic 
amyloidosis being treated with GSK3039294 alone. The design of the study, schedule of 
assessments, and oversight mean that any risks to participants are minimised including 
those which might potentially affect the kidney and heart, and therefore the clinical 
study is justified.

involvement
Section 5.4.4. Cardiac Arrhythmia Stopping Criteria
Additional Text and Figure:
All cardiac arrhythmias in individual subjects will be reviewed by the Investigator 
in consultation with the Medical Monitor at the earliest possible opportunity after 
the event, and will also be reviewed by a cardiologist where it is deemed appropriate 
to do so by the Investigator in consultation with the Medical Monitor on a case-by-
case basis.
A clinically concerning cardiac arrhythmia in this study is any type of arrhythmia 
or divergent QRS complex morphology that is deemed by the Investigator to be 
reasonably attributable to GSK3039294 - rather than within normal variation for 
each type of affected subject receiving repeat dose GSK3039294; i.e. healthy 
volunteer subjects in Part B, or systemic amyloidosis patients with known cardiac 
involvement Part C.
Furthermore, a clinically concerning arrhythmia is an adverse event which is 
deemed by the Investigator in consultation with the Medical Monitor to be of 
sufficient temporal duration and / or character to potentially affect subject safety. 
Detection of the following during baseline assessment or following administration of 
GSK3039294 will lead to withdrawal:

a). Sustained (≥ 10 beats) / symptomatic monomorphic ventricular tachycardia 
(VT), or rapid polymorphic VT; b). Complete heart block; c). Brady arrhythmias 
deemed clinically concerning by the Investigator in consultation with the Medical 
Monitor (i.e. except physiological bradycardia or first degree heart block).
Additional cardiac arrhythmic events could include, but are not restricted, to: 

A sustained arrhythmia (i.e. ≥30 seconds) except physiological bradycardia.

A non-sustained wide-complex tachyarrhythmia ≥ 100 / minute that is:
o
accompanied by symptoms or other new ECG changes (e.g. new ST 
depression)
o
repetitive (e.g. repeated short salvos)
o
Greater than 10 seconds in duration
Subjects who either have a clinically concerning arrhythmic event during the study, 
or where there is electrophysiological diagnostic uncertainty on cardiac telemetry / 
ECG, must be withdrawn from the study, and should have an immediate cardiac 
troponin level evaluated using a high-sensitivity point-of-care assay as outlined in 
Section 7.3.9 & Figure 5, below. 
Affected subjects should be referred to the local cardiology service and the Medical 
Monitor should be informed as soon as possible.

In Part C, the patient’s amyloidosis physician should be informed as soon as 
possible after any type of cardiac adverse event, by the Medical Monitor, 
irrespective of the patient’s cardiac amyloid status at Screening.
Section 5.4.6. Stopping Criteria Based On Disease Progression in Systemic 
Amyloidosis Patients in Part C
PREVIOUS TEXT
In Part C, individual patients can be withdrawn at any time during the study where the 
investigator has a reasonable level of clinical suspicion that the patient's underlying 
systemic amyloidosis is worsening. In this setting, the investigator in consultation with 
the Medical Monitor must refer the patient to their primary hospital physician for further 
consultation and appropriate diagnostic tests
REVISED TEXT
In Part C, individual systemic amyloidosis patients can be withdrawn at any time during 
the study where the investigator has a reasonable level of clinical suspicion that the 
patient's underlying systemic amyloidosis is worsening (including worsening cardiac 
dysfunction in those patients known to have cardiac amyloid involvement). In this

Cardiac Safety Monitoring in Cohort 3 (Part B) at Screening & Baseline
This will consist of a 48 hour Holter at Screening and continuous telemetry for 24 
hours immediately preceding the first dose of GSK303294 at baseline. 

In-Patient Dosing with GSK3039294: Continuous telemetry during repeat 7 
day dosing of healthy volunteer subjects in Cohort 3 will be performed for up 
to approximately 24 hours after Day 7 to detect any cardiac arrhythmias 
potentially attributable to repeat dosing with GSK3039294 for 7 days in 
Cohort 3.
Cardiac Safety Monitoring in Cohort 5 (Part C) patients with known cardiac 
amyloid involvement

Screening: 7-day out-patient cardiac monitoring using an appropriate non-
implantable recording device which is acceptable to the patient – this will 
evaluate the arrhythmic background of eligible cardiac amyloidosis patients 
such that false positive attribution of arrhythmias to GSK3039294 during 
repeat dosing will be minimized.

Baseline: 24 hour in-patient telemetry immediately before the first dose of 
GSK3039294.

In-patient dosing with GSK3039294: Continuous telemetry will be performed 
for up to 24 hours after Day 7 administration of GSK3039294 to detect any 
arrhythmias in patients with known cardiac amyloidosis potentially 
attributable to repeat dosing with GSK3039294 including worsening of 
known patient-specific arrhythmias from Screening and / or Baseline 
assessments.

Optional cardiac monitoring after completion of in-patient dosing: At 
Investigator discretion, on a case by case basis determined by in-patient 
cardiac telemetry / ECG findings, and in consultation with the Medical 
Monitor, cardiac monitoring can be extended either as an in-patient or as an 
out-patient (using a portable non-implantable device of Investigator 
choosing) in patients with known cardiac amyloidosis. 
Cardiac monitoring should continue in cardiac amyloidosis patients based on 
emerging safety data until it is deemed to be clinically appropriate for monitoring to 
stop after consultation with the Medical Monitor.

Cardiac Arrhythmia in Part B, or Part C 
Addition of Section:

149
Baseline hs-cTnT: In Part B  and Part C, all subjects will have hs-cTn level for 
purposes of screening as well as to provide baseline with which to compare, in the 
event that a subject develops a clinically concerning cardiac arrhythmic event after 
dosing with GSK3039294. 
Subjects should be advised by the local study site to abstain from strenuous exercise 
(e.g. running or gym work) ≤ 24 hours before a baseline hs-cTn level is taken.
Monitoring of hs-cTnT after an Arrhythmia Event: A blood samples for hs-cTnT 
will be taken immediately at the time of onset of a cardiac arrhythmia which is 
deemed by the Investigator to be of clinical concern (see Section 5.4.4), or where 
there is electrophysiological diagnostic uncertainty. 
High-sensitivity cTn levels should be serially repeated (using the same assay) 
following local troponin monitoring protocols at the study site, and with advice from 
a cardiologist if this is deemed clinically necessary by the Investigator. 
Additional investigations, including but not restricted to serial ECGs and evaluation 
of cardiac function using echocardiogram and / or cardiac magnetic resonance 
(CMR) imaging, can be performed at the discretion of the Investigator in 
consultation with the Medical Monitor and a cardiologist.

Design
Features
This will be a three-part open-label, non-randomised, dose-escalation 
study with no active or placebo control.
Part A will allow assessment of safety, tolerability and PK including 
biotransformation of GSK3039294 into active CPHPC of single doses 
of GSK3039294. If the absorption of GSK3039294 and subsequent 
biotransformation of GSK3039294 to CPHPC is sufficient then repeat 
dosing will be investigated in Part B.
Part B will allow assessment of safety, tolerability and PK including
evaluation of food-effect and biotransformation of GSK3039294 into 
active CPHPC of repeat doses of GSK3039294 and PD (depletion of 
plasma SAP). PK and PD data will be compared within a subject 
following repeat dosing and dose escalation and regimen adjustments. 
If the exposure to CPHPC and the resulting depletion of SAP is 
sufficient and well tolerated, then repeat dosing of patients with 
systemic amyloidosis will be investigated in Part C.
Part C will confirm the ability of GSK3039294 (dosing regimen
determined from Part B) to decrease plasma SAP to a level suitable for 
mAb administration in subsequent studies and its ability to maintain 
this level over 21 days in patients with systemic amyloidosis. Also, 
safety and tolerability of the optimal clinical dose of GSK3039294 will 
be evaluated in systemic amyloidosis patients which may include those 
with known cardiac amyloid involvement.
Dosing
This study is planned to test single doses of GSK3039294 and repeat 
doses up to the maximum tolerated dose or the maximum allowable 
dose based on pre-clinical findings. 
Part A

The starting dose in Part A is planned to be 200mg of 
GSK3039294. This dose has been selected using the PK/PD model 
that was developed for CPHPC (active molecule), adjusted for the 
oral absorption of GSK3039294 and the conversion of 
GSK3039294 to CPHPC. 

The next doses in Part A will be determined based on the data of 
the preceding dosing sessions. All available PK data will be 
analysed and the next dose will be such that the predicted median 
Cmax will be about 6 g/mL, and the upper limit of the 95% 
prediction interval will not exceed preclinical Cmax and AUC 
limits.

The highest dose in Part A will not exceed pre-clinical safety 
exposure limits of AUC[0-24] of 250 g.hr/mL and Cmax of 
22.1g/mL.
Part B

The dose levels for Cohort 3 in Part B will be determined based on 
the PK data obtained in Part A, by analysing all available PK data 


CONFIDENTIAL
201664
12
from Part A and subsequently predicting concentration-time 
profiles at steady state after repeat dosing. 

The dose levels for subsequent cohorts in Part B will be determined 
based on the PK data from Part A (single dose) and cohort 3 in Part 
B (multiple dose). The dose levels and dosing frequencies will be 
chosen such that the upper limit of the 95% prediction interval for
Cmax and AUC at steady state will not exceed preclinical Cmax 
and AUC limits (22.1 g/mL and 250 g.hr/mL, respectively).
Part C

GSK3039294 will be administered at the predicted optimal clinical 
dose for 21 days. This dose will be determined using the PK/PD 
model that was developed for CPHPC (active molecule) and using 
all available PK and plasma SAP (PD) data from Parts A and B, the 
model will be adjusted for the oral absorption of GSK3039294 and 
the conversion of GSK3039294 to CPHPC. The dose level and 
frequency will be chosen such that the upper limit of the 95% 
prediction interval for Cmax and AUC at steady state will not 
exceed preclinical Cmax and AUC limits (22.1 g/mL and 
250 g.hr/mL, respectively).
Treatment 
Assignment

This is an open-label, non-randomised study with no active or 
placebo control.

GSK3039294 doses will be administered sequentially and will be 
based on the review of safety, PK and PD data (as applicable) from 
previous cohorts, dosing sessions and study parts. 
Interim 
Analysis

The planned protocol-defined unblinded interim analyses are: 
[1] Ongoing data reviews throughout the study
[2] Data reviews to inform dosing decisions for subsequent dosing 
sessions, cohorts and study parts
[3] At the end of Part B, interim analysis of selected renal safety 
data.

PLANNED ANALYSES
3.1.
Interim Analyses
Data will be reviewed on an ongoing basis throughout the study by the study team and 
investigator in order to inform dosing decisions for subsequent dosing sessions, cohorts 
and study parts. Dose escalation meetings will be held prior to increasing the dose. Key 
data to inform dosing decisions will include but not be limited to: safety (AEs, clinical 
laboratory data, vital signs and ECGs), PK (concentrations of GSK2315698, and if 
possible GSK3039294), and plasma SAP levels.


CONFIDENTIAL
201664

Data listings direct from the PIMS (Patient Information Management System) data 
capture system will facilitate ongoing reviews of safety data.
To inform dosing decisions for subsequent dosing sessions in Part A, individual values of 
Cmax and AUC[0-inf] will be derived by means of non-compartmental analysis. 
Assuming linear kinetics, the next dose will be such that the upper limit of the 95% 
prediction interval for Cmax and AUC will not exceed preclinical safety limits (22.1 g 
/mL and 250 g.hr/mL, respectively).
To inform dosing decisions for subsequent study parts, GSK2315698 concentration data 
and plasma SAP levels will be analysed using the PK/PD model that was developed for 
GSK2315698 [Sahota, 2015].  Based on pre-clinical data it is expected that the 
conversion of GSK3039294 to GSK2315698 is very fast. Therefore, it can be assumed 
that this conversion will occur mainly during the absorption phase, and that the 
distribution and elimination of GSK2315968 are not altered. Hence, all distribution and 
elimination parameters (PK/PD) will be fixed to the reported parameter estimates, and 
only bioavailability (F) and absorption related parameters (e.g. Ka) will be estimated. 
Nominal time points will be used. This updated model will be used to simulate 
concentration-time data and plasma SAP levels using different dose levels and dosing 
regimens, which will be used to inform dosing decisions for subsequent dosing sessions, 
cohorts and study parts.
In addition to the ongoing review of data throughout the study, at the end of Part B, 
individual profiles over time will be presented graphically for selected urine and plasma 
laboratory parameters pertaining to the kidney (including, but not limited to: blood & 
urine glucose, urine protein, serum creatinine, urine protein/urine creatinine ratio, serum 
phosphate, urine pH, and arterial blood gas test results (blood pH and blood bicarbonate)
if available.  Note, an arterial blood gas test will only be performed if urine pH is 
abnormal, i.e. acidic. Individual profiles will be presented for both single (Part A) and 
repeat-dose (Part B) healthy volunteer data to further inform the evaluation of renal 
safety and the decision to progress to repeat dosing in patients in Part C.

Pharmacokinetic / Pharmacodynamic Analyses

The primary goal of this analysis is to recommend the dose regimen that adequately 
reduces plasma SAP levels when the active moiety, GSK2315698, is administered as 
an oral prodrug, GSK3039294, to subjects with amyloidosis.

A summary of the planned population pharmacokinetic/pharmacodynamic analyses 
is outlined below:
o GSK2315698 plasma concentration – pharmacodynamic data (plasma SAP) 
obtained from healthy volunteers and patients with systemic amyloidosis will be 
analysed using the PK/PD model that was developed for GSK2315698 [Sahota, 
2015] using the program NONMEM to develop a population PK/PD model.
o This PK/PD model will be adjusted for oral absorption of GSK3039294 and 
conversion into GSK2315698.

Baseline Definition & Derivations
10.3.2.1.
Baseline Definitions
For all endpoints, the baseline value will be the latest pre-dose assessment within a given 
study part, i.e. Day 1 (pre-dose) if available, or Day -1 if Day 1 (pre-dose) not available, 
or Screening if Day -1 and Day 1 (pre-dose) not available.

Derivations and Handling of Missing Baseline Data
Change from Study Part Baseline = Post-Dose Visit Value – Study Part Baseline.
If baseline data is missing no derivation will be performed and it will be set to missing.

General
’Any Visit Post-Baseline’ Timepoint for Summaries

Subjects having both High and Low values for Normal Ranges at any post-baseline visits for 
safety parameters will be counted in both the High and Low categories of “Any visit post-
baseline” row of related summary tables. This will also be applicable to relevant Potential 
Clinical Importance summary tables.
Study Part Day

Calculated as the number of days from randomisation date for given study part:

Ref Date = Missing
→ Study Part Day = Missing

Ref Date < Randomisation Date → Study Part Day = Ref Date – Randomisation Date

Ref Data ≥ Randomisation Date → Study Part Day = Ref Date –(Randomisation Date)+1
10.4.2.
Study Population
Demographics
Age

GSK standard IDSL algorithms will be used for calculating age where birth date is imputed as:

Any subject with a missing day will have this imputed as day ‘15’. 

Any subject with a missing day and month will have this imputed as ‘30th June’.

Birth date will be presented in listings as ‘YYYY’.
Body Mass Index (BMI)

Calculated as Weight (kg) / [Height (m)2]
Extent of Exposure

Exposure will be calculated/presented by study part.

Number of days of exposure to study drug will be calculated based on the formula:  
Duration of Exposure in Days = Treatment Stop Date – (Treatment Start Date) + 1

Subjects who were randomized but did not report a treatment start date will be categorised as 
having zero days of exposure. 

The cumulative dose will be based on the formula:
Cumulative Dose = Sum of (Number of Days x Total Daily Dose)

If there are any treatment breaks during the study, exposure data will be adjusted accordingly.

and all available planned data will be included in summary tables and figures, 
unless otherwise specified.
10.5.2.
Handling of Missing Data
Element
Reporting Detail
General

Missing data occurs when any requested data is not provided, leading to blank 
fields on the collection instrument:

These data will be indicated by the use of a “blank” in subject listing 
displays. Unless all data for a specific visit are missing in which case the 
data is excluded from the table. 

Answers such as “Not applicable” and “Not evaluable” are not considered to 
be missing data and should be displayed as such.
Outliers

Any subjects excluded from the summaries and/or statistical analyses will be 
documented along with the reason for exclusion in the clinical study report.
10.5.2.1.
Handling of Missing/Partial Dates
Element
Reporting Detail
General
Partial dates will be displayed as captured in subject listing displays.
Adverse 
Events

The eCRF allows for the possibility of partial dates (i.e., only month and year) to 
be recorded for AE start and end dates; that is, the day of the month may be 
missing. In such a case, the following conventions will be applied for calculating 
the time to onset and the duration of the event:

Missing Start Day: First of the month will be used unless this is before the 
start date of investigational product; in this case the study treatment start 
date will be used (and hence the event is considered On-treatment as per 
Appendix 2: Treatment States and Phases).

Missing Stop Day: Last day of the month will be used, unless this is after the 
stop date of study treatment; in this case the study treatment stop date will 
be used.

Completely missing start or end dates will remain missing, with no imputation 
applied. Consequently, time to onset and duration of such events will be 
missing.

Concomitant 
Medications

Partial dates for any concomitant medications recorded in the CRF will be 
imputed using the following convention:

If the partial date is a start date, a '01' will be used for the day and 'Jan' will 
be used for the month

If the partial date is a stop date, a '28/29/30/31' will be used for the day 
(dependent on the month and year) and 'Dec' will be used for the month.

The recorded partial date will be displayed in listings.

Appendix 7: Pharmacokinetic / Pharmacodynamic Analyses
10.7.1.
Systems
All non-linear mixed effects modelling will be performed using NONMEM (ICON 
Solutions) and PsN (Perl Speaks NONMEM). R (The R Foundation for Statistical 
Computing) will be used for exploratory graphical analysis, graphical model diagnostics 
and, if needed, modifications of the dataset. The analysis will be performed by, or under 
the direct auspices of, CPMS, GlaxoSmithKline in the GSK modelling environment PME 
(Predictive Modelling Environment) using the currently supported versions of all 
software packages.
10.7.2.
Data Assembly
The merge of PK, PD, regimen and CRF data together with the creation of the 
NONMEM-specific dataset will be performed by, or under the direct auspices of, Clinical 
Statistics (Programmer), GlaxoSmithKline. This dataset programming will be conducted 
in the GSK Harmonisation for Analysis and Reporting Program (HARP) environment 
using the currently supported version of SAS. The dataset will be consistent with the 
specifications summarised in Section 10.7.5.
10.7.3.
PK/PD Modelling of GSK2315698 and SAP Concentrations
An exploratory graphical analysis of the data will be performed by generating the plots as 
presented in Appendix 9: List of Data Displays.
A PK/PD model for GSK2315698 and its effect on plasma SAP levels was developed 
previously [Sahota, 2015]. Covariates in this model are creatinine clearance (affecting 
GSK2315698 clearance), subject gender (affecting SAP baseline), and baseline amyloid 
load (affecting SAP distribution). Because of the target mediated drug disposition 
(TMDD) of GSK2315698, PK and PD will be analysed simultaneously, or parameters of 
either PK or PD will be fixed to reported estimates while exploring PD or PK, 
respectively.
As a first step the oral absorption of GSK3039294 and conversion into GSK2315968 will 
be added to the model. To that end, all available plasma GSK2315968 data will be 
analysed using the PK/PD model, extended with first order absorption and oral 
bioavailability. Based on preclinical data it is expected that the conversion of 
GSK3039294 to GSK2315698 is very fast. Therefore, it will be assumed that this 
conversion will occur mainly during the absorption phase, and that the distribution and 
elimination of GSK2315698 are not altered. GSK3039294 and the intermediate molecule 
GSK3037412 do not affect plasma SAP levels, and therefore it will be assumed that the 
PK/PD relationship between GSK2315698 and SAP is not changed.
Summarising, this means that for the first step all distribution and elimination parameters 
and all PD parameters will be fixed to the reported parameter estimates, and only 
bioavailability (F) and absorption related parameters (e.g. Ka) will be estimated. If a 
simple first order process for oral absorption and conversion is not sufficient to describe 


CONFIDENTIAL
201664
48
the data (e.g. in case the conversion does not occur very fast), the part of the PK/PD 
model describing the absorption and conversion into GSK2315698 will be developed in a 
data driven fashion.
Subsequently, using the PK/PD model updated for oral absorption of GSK3039294 and 
conversion into GSK2315698, visual predictive checks (VPCs) will be conducted to 
assess graphically whether simulations from the PK/PD model are able to reproduce both 
the central trend and variability in the observed SAP concentrations from the current 
study as a function of time.
This VPC will be based on 1000 simulations with the model and the design structure of 
the observed data (i.e. dose level and time, time of SAP sampling and individual values 
of model covariates). The median and the 5th and 95th percentiles (or 10th and 90th, 
dependent on the size of the final dataset) will be compared to the observed data. 
Applicable stratification, such as dose level of GSK3039294 and baseline amyloid load, 
will be used.
If the VPC shows a difference between the simulated and observed PK, it will be 
investigated if the population PK/PD model can be adjusted with the current PK and SAP 
data. This process will be data driven.
10.7.4.
Diagnostics
Model acceptability will be judged by convergence, covariance estimation and standard 
goodness-of-fit plots that may include, but are not limited to:

Population and individual predictions versus observations

Conditional weighted residuals versus population predictions and time.
For the final PK/PD model, visual predictive checks (VPCs) will be conducted as 
described in Section 10.7.3.
10.7.5.
Specifications for NONMEM-specific Dataset
The concentration dataset will be a comma delimited text file, named 
“NM_GSK2315698_201664_PKPD_v1.csv”. The version number will be updated each 
time a new version is created and issued.
This file will include events of dosing, GSK3039294, GSK2315698 or SAP 
concentration as rows, with the variables in the table below as columns. Rows will be in 
increasing order of unique subject identification number; and all events in the same 
subject must be consecutive and in chronological order, ending with the last 
GSK3039294 / GSK2315698 / SAP concentration event (i.e. dosing events that occur 
after the last quantifiable concentration in a subject will not be included in the data file).
Non-numerical concentration values (such as missing samples, not assayed samples, non-
quantifiable samples or non-reportable samples) will not be included. Subjects with no 
quantifiable concentration values will not be included.
