Enrollment: 8
Healthy volunteers: no

Brief summary:
GSK3008348 is being developed as a treatment for IPF. A first-time-in-human study showed that single nebulized doses of 1-3000 micrograms (mcg) GSK3008348 in healthy volunteers were well tolerated, with pharmacokinetic (PK) exposures within the defined limits set in the protocol. The proposed study is a 2-cohort study of single doses, intended to evaluate the safety, tolerability and PK of the drug in participants with IPF not currently treated with pirfenidone or nintedanib, and to obtain preliminary information on target engagement. Cohort 1 will be a 2-period, randomized, double-blind, placebo-controlled group with at least 7 days washout between doses, and follow-up period of up to 7-14 days. Cohort 2 is optional. It will be designed to further explore safety and to provide additional information on the target engagement profile of GSK3008348. The total duration of the study will be up to 62 days.

Detailed description:

SYNOPSIS
Protocol Title: A study of single doses to evaluate the safety, tolerability, 
pharmacokinetics and target engagement of nebulised GSK3008348 in idiopathic 
pulmonary fibrosis patients, using positron emission tomography (PET) imaging
Short Title: Single doses of GSK3008348 in IPF patients using PET imaging
Rationale:  GSK3008348 is a potent and selective inhibitor of the integrin receptor αvβ6, 
and is being developed as a treatment for idiopathic pulmonary fibrosis (IPF).  It has been 
shown to engage αvβ6 integrin and inhibit downstream fibrogenic mechanisms in mouse 
and human lung cells and tissue.  The first-time-in-human study (GSK Document 
Number 2014N201929_01, Study 200262) showed that single nebulised doses of 
1−3,000 µg GSK3008348 in healthy volunteers were well tolerated, with 
pharmacokinetic (PK) exposures within the defined limits set by the protocol.  The 
proposed study is intended to evaluate the safety, tolerability and pharmacokinetics of the 
molecule in patients with IPF not currently treated with pirfenidone or nintedanib, and 
obtain preliminary information on target engagement to support progression to repeat 
dose and proof of mechanism studies.  Target engagement will be measured by positron 
emission tomography (PET) using a radiolabelled αvβ6-specific ligand, [18F]-FBA-
A20FMDV2 (GSK2634673).    
Objectives and Endpoints:


To evaluate duration of target engagement 
after single nebulised doses of 
GSK3008348 in IPF patients

Changes in the uptake of [18F]-FBA-
A20FMDV2 in the lung (assessed as the 
VT) up to 28 h post-dose compared to pre-
dose, as measured by PET
Overall Design:
This is a multi-centre, 2-cohort, study of single doses to investigate the safety, 
tolerability, PK and target engagement of nebulised GSK3008348, in patients with IPF. 
Hospital-based clinical units will recruit and enrol participants; PET imaging will be done 
at a specialist imaging unit.  All participants will be screened up to 30 days before their 
first dose, will have 2 planned dosing periods, and will have a follow-up visit at 7–14 
days post-last dose.  
Cohort 1 will be a randomised, double-blind (sponsor unblind), placebo-controlled group 
of 7 participants, randomised 5:2 to receive 1,000 µg GSK3008348 or placebo.  Safety 
and tolerability will be assessed in dosing period 1, and PET scans in dosing period 2 will 
be used to assess target engagement of GSK3008348.  
After completion of Cohort 1, safety, PET and PK data will be reviewed. 
Cohort 2 is optional, and will be designed to further explore the safety and to provide 
additional information on the target engagement profile of GSK3008348, such that each 
participant has up to 3 PET scans and 2 planned doses of GSK3008348.  
Refer to Figure 1 for a schematic illustrating the study design.

Number of Participants:
It is anticipated that up to 21 participants will be randomized. 
Treatment Groups and Duration:
Cohort 1
Cohort 2
Screening
Within 30 days of the first dose.
Dosing 
Period 1
After pre-dose assessments at the 
clinical unit, participants will be 
admitted to the clinical unit the day of 
dosing (Day 1), stay overnight and be 
discharged after 24 h post-dose safety 
and PK assessments (Day 2). 
After pre-dose assessments at the 
clinical unit, participants will attend the 
clinical unit for dosing (Day 1) and stay 
for at least 8 h post-dose for safety and 
PK assessments.  Participants will return 
on Day 2 for 24 h post-dose safety and 
PK assessments.
Washout 
Period
At least 7 days and no more than 28 days between doses.  
Baseline 
PET scan
At least 7 days after the first dose, and no more than 14 days before the first 
post-dose PET.
Dosing 
Period 2
Participants will have pre-dose 
assessments at the clinical unit.  They 
will attend the imaging unit for dosing 
and a 30 min post-dose PET scan, and 
stay for at least 4 h post-dose.  
Participants will return to the imaging 
unit on Day 2 for a 24 h PET scan, and 
safety and PK assessments.
Participants will have pre-dose 
assessments at the clinical unit.  They 
will attend the clinical or imaging unit for 
dosing and will stay for at least 4 h post-
dose.  Participants will have up to 2 
post-dose PET scans on Days 1 or 2, at 
times to be determined after review of 
Cohort 1 data.
Follow-up
At least 7 days and no more than 14 days after the final dose.  If warranted, 
additional follow-up visits may be scheduled.
If a participant withdraws from the study prior to the final dose, the follow up visit 
should occur within 14 days of withdrawal unless a separate timepoint is agreed by 
the principal investigator and medical monitor
Study 
Duration
Up to 62 days
Treatment 
Arms
Participants will receive a single nebulised dose of GSK3008348 or placebo during 
each of 2 planned dosing periods. 
Participants will receive up to 3 microdose administrations of [18F]-FBA-A20FMDV2 
for the PET scanning.  The maximum amount of radioactivity injected during each 
PET scan will be 150 MBq and maximum mass of [18F]-FBA-A20FMDV2 
administered across the 3 administrations will be 100 µg.

INTRODUCTION
3.1.
Study Rationale
GSK3008348 is a potent and selective inhibitor of the integrin receptor αvβ6, and is 
being developed as a treatment for idiopathic pulmonary fibrosis (IPF).  It has been 
shown to engage αvβ6 integrin and inhibit downstream fibrogenic mechanisms in mouse 
and human lung cells and tissue.  The first-time-in-human study (GSK Document 
Number 2014N201929_01 Study 200262) showed that single nebulised doses of 
1−3,000 µg GSK3008348 in healthy volunteers were well tolerated, with 
pharmacokinetic (PK) exposures within the defined limits set by the protocol.  The 
proposed study is intended to evaluate the safety, tolerability and PK of the molecule in 
patients with IPF not currently treated with pirfenidone or nintedanib, and obtain 
preliminary information on target engagement to support progression to repeat dose and 
proof of mechanism studies.  Target engagement will be measured by positron emission 
tomography (PET) using a radiolabelled αvβ6-specific ligand, [18F]-FBA-A20FMDV2 
(GSK2634673).    
3.2.
Background
IPF is a form of chronic fibrosing interstitial pneumonia, limited to the lung and 
associated with the histological appearance of usual interstitial pneumonia (UIP) on 
surgical lung biopsy.  The aetiology of IPF is unknown; it progresses in a relentless and 
often insidious manner that may be difficult to detect using parameters such as 
symptomatology, chest radiographic findings, or spirometry alone. Spontaneous 
remissions do not occur, and mean survival ranges from 2 to 4 years (5-year survival 
range, 30 to 50%). 
In the United Kingdom, data from general practice shows that the 12 month prevalence is 
15−18/100,000 person and an incidence of about 5/100,000 person-years.  Approximately 
2,000 new cases of IPF are diagnosed each year in England and Wales
[Navaratnam, 2013]. 
No therapy has been demonstrated to reverse the progression of IPF and it remains a 
major indication for lung transplantation. Two oral therapies are currently marketed for 
IPF, pirfenidone (Roche), the mechanism of action for which is incompletely understood
and nintedanib (Boehringer Ingelheim), a kinase inhibitor. Both of these treatments 
demonstrate a reduction in the rate of decline in lung function (forced vital capacity 
[FVC]) over one year [King, 2014; Richeldi, 2014]. Pirfenidone is associated with 
phototoxicity, and both agents have significant gastrointestinal effects.  In a real-world 
study, treatment with pirfenidone led to discontinuation in approximately one third of 
patients due to adverse events [Hughes, 2016].
The association of transforming growth factor (TGF)activity with fibrosis has been 
established in many disease settings. TGFis secreted in an inactive form, and requires 
activation post-translationally.  Substantial evidence suggests that the v6 integrin 
performs a key TGFactivation function at sites of damaged epithelium [Margadant, 
2010].  Activation of TGFby v6 has been shown to play an important role in lung

fibrosis: 6 knockout mice are resistant to bleomycin-induced pulmonary fibrosis 
[Munger, 1999] and treatment with an αvβ6 neutralising antibody ameliorates bleomycin 
[Horan, 2008] and radiation-induced pulmonary fibrosis [Puthawala, 2008].
Immunohistochemistry of lung biopsy has shown that αvβ6 is significantly increased in 
the fibrotic areas of the lungs of IPF patients [Horan, 2008].  Expression levels of αvβ6 in 
IPF lungs predict mortality, with highest expression levels in IPF patients who progress 
rapidly [Saini, 2013]. In addition, animal models of pulmonary fibrosis have shown that 
the expression of αvβ6 correlates with the severity of the fibrotic response, and blockade 
of this target reduces the fibrosis [Horan, 2008; Puthawala, 2008]. Inhibition of v6 is 
considered to be advantageous over direct TGFinhibition because v6 expression is 
highly regulated and localised to damaged epithelial sites. Thus, inhibition of integrin-
mediated TGFactivation should minimise the risk of potential side effects caused by 
direct TGFinhibition, e.g. pro-inflammatory responses. 
GSK3008348 is being progressed as a twice-daily small molecule anti-fibrotic medicine,
to be delivered to IPF patients’ lungs by nebulisation. On reaching the peripheral areas of 
the lung, where the fibrosis occurs, GSK3008348 will bind to v6 on the damaged 
epithelium.  Our non-clinical work indicates that binding leads to internalisation of the 
integrin, inhibiting v6-mediated activation of TGFβ. The ability of TGFβ to promote 
collagen production by activated myofibroblasts is thereby limited.  It is hypothesised 
that GSK3008348 will slow or stop the progression of fibrosis, with the potential to 
provide significant benefit to patients in terms of reduction, avoidance or delay of 
symptoms, disability and death.
A 20 amino acid peptide (A20FMDV2), derived from the foot and mouth disease virus
(FMDV2), has been synthesised and shown to bind selectively to v6 (KD =0.22nM). 
The radiolabelled peptide, [18F]-FBA-A20FMDV2, will be used in this study to quantify 
levels of v6 expression and GSK3008348 receptor engagement in the lungs of IPF 
patients.  A single photon emission computed tomography (SPECT) analogue, 
[111In]-FBA-A20FMDV2, has been shown non-clinically to bind specifically to αvβ6 in 
the lungs of mice [John, 2013] and similar results have been obtained using the PET 
ligand in rats [internal GSK data on file].  [18F]-FBA-A20FMDV2 has also been 
administered to humans and shown to provide a signal that allows the distinction between 
IPF patients and healthy participants (GSK Document Number 2013N163906_00 Study 
RES116235).

Benefit/Risk Assessment
Information on the key potential risk associated with GSK3008348 and the strategies to 
mitigate this risk are detailed below in Section 3.3.1.  Further details about the potential 
risks and expected benefits of GSK3008348 may be found in the Investigator’s Brochure

Potential local irritancy
Non-clinical:
Upper respiratory tract irritancy was observed in the 4-week 
inhalation toxicity studies in rats and dogs. Principal changes 
included epiglottic cartilage necrosis, regeneration/ 
remodelling at 5850 and 12000 µg/kg/day in rats; and soft 
palate or laryngeal ulcerations in dogs at 3070 and 
8710 µg/kg/day. No Observed Adverse Effect Levels
(NOAELs) were identified at the lowest doses tested (1420 
and 899 µg/kg/day in rats and dogs, respectively).
Lower respiratory tract irritancy was also observed in the 4-
week inhalation toxicity study in dogs. Adverse mixed 
inflammation and alveolar macrophage aggregates were 
observed at 3070 and 8710 µg/kg/day. These findings were 
also present in some animals from the lowest dose tested 
(899 µg/kg/day – the NOAEL), including control. Changes in 
local draining lymph nodes of GSK3008348-treated dogs were 
considered to be a non-adverse secondary response to the 
pulmonary inflammation. 
Non-adverse alveolar macrophage aggregates were seen at a 
low incidence in the lungs of all treated groups and also in 
control males in the 4-week inhalation study in rats. A minor 
test article-related effect could not be entirely discounted in 
female rats. 
In this planned first-time-in-patient study, IPF patients 
will only receive single doses. 
Appropriate inclusion/exclusion criteria (e.g., exclusion 
for current upper or lower respiratory tract infection) will 
be implemented in clinical protocols.
Potential adverse events associated with irritancy (e.g., 
sore throat, cough, dyspnoea, wheezing) are readily 
monitored, and will be monitored during the study. 
Interpretation of these AEs may be compromised in IPF 
patients where cough or dyspnoea may be symptoms 
of their respiratory diseases. Therefore patients’ 
baseline symptoms will be recorded as part of the 
current conditions assessment, and physical 
measurements including respiratory rate and oxygen 
saturation monitoring reviewed, to aid interpretation of 
any new symptoms. It is anticipated that symptoms 
secondary to irritancy will be more acute in nature, 
which will help distinguish from chronic symptoms due 
to IPF.
Symptoms of clinical concern may be investigated 
further in collaboration with an Ear, Nose and Throat

Study Procedures
Participants exposed to 
ionising radiation as a 
consequence of patient’s 
participation in this study. 
The ionising radiation exposure comes from the administered 
radioligand, a high resolution CT (HRCT) for anatomical 
localization and low dose CT scans performed in order to 
correct the PET data for tissue attenuation.  The maximum 
effective dose of ionising radiation that participants in this 
study may be exposed to is 20.9 mSv.  This is equivalent to 
approximately 9 times the average yearly exposure (2.3 mSv) 
from natural background radiation in the United Kingdom.
The additional risk of developing a fatal malignancy as a result 
of these exposures has been estimated as approximately 1 in 
1,000 for an adult in normal health. The reduced life 
expectancy of IPF patients will result in a lower risk for these 
individuals.
Within the UK the guidance set out by International 
Commission on Radiological Protection (ICRP) 62 is generally 
followed in setting research study dose constraints. The level 
of risk may therefore be assumed to broadly fall within the 
ICRP 62 intermediate Category IIb, where the benefit should 
be more directly aimed at the cure or prevention of disease.
The study has been designed to keep the radiation 
dose as low as reasonably practicable whilst obtaining 
images of sufficient quality to meet the objectives.
Male participants < 50 years and female participants 
< 55 years will not be eligible.
To avoid recruitment of radiation worker or serial study 
volunteers, participants who have been exposed to 
ionising radiation in excess of 10mSv above 
background over the previous 3 year period as a result 
of occupational exposure to radiation or as a result of 
research studies are excluded.  Clinically justified 
(therapeutic or diagnostic) exposures are not included 
in the exposure calculation.  Participants are asked 
about any occupational exposure or previous 
participation in research studies at screening so that 
dose estimates can be obtained where necessary.
The study will exclude women of childbearing potential.

Appendix 8. 
Potential risk of 
immunogenicity related to 
A20FMDV2
There is a low theoretical risk that [18F]-FBA-A20FMDV2 may 
be immunogenic in humans. This could potentially lead to 
reduced signal in PET scans from neutralising anti-drug 
antibodies. There is also potential for anaphylactic and other 
immune mediated reactions. Neither of these phenomena has 
been observed in previous administrations of [18F]-FBA-
A20FMDV2 to humans (ongoing GSK Study RES116235).
[Of note, assay for measurement of antibodies to [18F]-FBA-
A20FMDV2 produced positive results in two participants in 
study RES116235. One healthy participant was positive pre-
and post-dosing, and one IPF participant was positive after the 
first scan and negative after the second scan. No clinical 
effects were attributed to effects of antibodies.]
Exclusion of participants with prior exposure to farm 
animals that may harbour FMDV2.
Exclusion of participants from countries where FMDV2 
is endemic.
Short period between repeat PET scans.
Collection of serum samples for measurement of 
antibodies to [18F]-FBA-A20FMDV2.
PET scans performed in an imaging unit with 
immediate access to emergency measures. 
Refer to Appendix 9 for more detail on the 
immunogenicity risk assessment and mitigation.
Potential bystander exposure 
to GSK3008348
Unintended inhalation of GSK3008348 (irritant potential).  
Since clear NOAELs were established in the nonclinical 
toxicity studies (with adequate safety margins) and the 
concentration in the room will be significantly less than direct 
exposure to GSK3008348, the risk for irritancy for bystanders 
is considered to be low.
No events in bystanders were reported in the study in healthy 
volunteers following single doses up to 3,000 µg.
Appropriate precautions will be taken to minimise 
bystander exposure in the study. Nebulised drug 
should not be administered in a confined and/or 
unventilated space.

Ensuring sufficient medical 
oversight for safety 
monitoring and transport 
between sites
In dosing period 2 of Cohort 1, the doses will be administered 
to participants in the imaging unit, so that the PET can be 
carried out at approximately 30 minutes post-dose.  However, 
in Cohort 2, there is the option to administer those doses in 
the hospital clinical unit, if required for logistical or safety 
reasons.  In that case, participants would be transported after 
dosing to the imaging site for the PET scans.
In both Cohorts 1 and 2, the first dosing period will be 
conducted in a hospital-based clinical unit, under the 
supervision of a chest physician, with immediate 
access to facilities for the treatment of medical 
emergencies, facilities for stabilizing individuals in an 
acute emergency and ready availability of Intensive 
Care Unit facilities. Following Principal Investigator (PI) 
and GSK medical monitor review of the individual 
safety and tolerability data from the completed first 
dosing period, the patient will continue to the baseline 
PET visit and second dosing period. In the second 
dosing period, the same dose will be administered by 
clinical staff in the imaging unit, alongside an 
appropriately trained research nurse.
If in Cohort 2 doses are to be administered in the 
clinical unit before transporting participants to the 
imaging unit in dosing period 2, patients will be 
observed for at least 4 hours post-dose before being 
transported to the imaging unit.

Benefit Assessment
Participants will receive single doses of GSK3008348, which is being developed as a 
treatment for IPF.  It is not anticipated that this single dose study will provide any clinical 
benefit to participants.  The results will inform the evaluation of GSK3008348 as a 
treatment for IPF, so participants may contribute to the process of developing new 
therapies for IPF and related conditions.  Participants will be monitored throughout the 
study for any worsening of IPF symptoms or decline in general health.
3.3.3.
Overall Benefit:Risk Conclusion
Taking into account the measures taken to minimize risk to participants participating in 
this study, the potential risks identified in association with single doses of GSK3008348 
and with study procedures are justified by the anticipated benefits from active treatment
that may be afforded to patients in the future, in developing GSK3008348 as a new 
therapy for IPF.

STUDY DESIGN
5.1.
Overall Design
This is a multi-centre, 2-cohort, study of single doses to investigate the safety, 
tolerability, PK and target engagement of nebulised GSK3008348, in patients with IPF. 
Hospital-based clinical units will recruit and enrol participants; the PET imaging will be 
done at a specialist imaging unit.  
Participants will be screened up to 30 days before their first dose, and will have a 
follow-up visit at 7–14 days post-last dose.  
Refer to Figure 1 for a schematic illustrating the study design.
5.1.1.
Cohort 1
Cohort 1 will be a randomised, double-blind (sponsor unblind), placebo-controlled group 
of 7 participants, randomised 5:2 to receive 1,000 µg GSK3008348 or placebo.  All 
participants will have 2 planned dosing periods, and receive the same dose in each period.  


2016N291965_02
CONFIDENTIAL
204715
22
Dosing period 1 aims to assess safety and tolerability, and dosing period 2 aims to assess 
target engagement using PET imaging. 
In dosing period 1, participants will be admitted to the clinical unit on the morning of 
Day 1 for pre-dose health assessments and a pharmacogenetic sample; these assessments 
may also take place on Day –1.  On Day 1, they will remain in the clinical unit overnight, 
to enable safety assessments to be carried out for at least 24 h after receiving their 
nebulised dose.  PK and exploratory biomarker samples will also be taken.  Participants 
will then be discharged from the clinical unit. 
There will be a washout of between 7 and 28 days between doses in periods 1 and 2.  
Participants will attend the imaging unit for a baseline PET scan and a high resolution 
computerised tomography (HRCT) scan, at least 7 days after their first dose, and a 
maximum of 14 days before their first post-dose PET scan in dosing period 2.  
In dosing period 2, participants will first attend the clinical unit for pre-dose health 
assessments, on Day 1 or Day −1.  If they pass the health assessments, participants will 
attend the imaging unit for dosing and a PET scan starting approximately 30 min post-
dose (i.e., post the start of nebulisation).  Participants will remain in the imaging unit for 
safety observation for at least 4 h post-dose on Day 1, and then return on Day 2 for a PET 
scan at approximately 24 h post-dose (post the start of nebulisation).  Safety assessments 
and PK sampling will be done throughout those visits.  
Cohort 1 will be considered complete when PET data at 30 min post-dose has been 
collected from 7 participants.  After completion of Cohort 1, blinded safety and PK data 
will be reviewed by a data review team, consisting of the investigators, medical monitor, 
statistician, clinical pharmacokineticist, pharmacovigilance representative, and clinical 
study team members, as appropriate.  The statistician will also perform an unblinded 
review of the PET data. 
5.1.2.
Cohort 2
Cohort 2 is optional, and will proceed only if there is evidence of target engagement at 
30 min post-dose in Cohort 1.  It will be designed to further explore the safety and to 
provide additional information on the target engagement profile of GSK3008348.  
Decisions on whether to proceed with Cohort 2, and on the most informative design for 
Cohort 2, will be based on Cohort 1 data.  Cohort 2 data may be reviewed in-stream and 
the design of Cohort 2 adjusted to maximise the value of the data obtained.  Cohort 2 will 
be designed such that each participant will have up to 3 PET scans and 2 planned doses 
of GSK3008348, and within the logistical limitations of dosing, safety monitoring, PET 
ligand radiochemistry and PET scanning.  For example: 

If there is no evidence of target engagement at 30 min post-dose in Cohort 1, then 
Cohort 2 will not go ahead. 

If the variability in PET measurements is higher than anticipated, participants in 
Cohort 2 may follow the same dosing and scanning regime as in Cohort 1, to 
increase the sample size.

23

If significant target engagement is observed at 30 min in Cohort 1, but there is no 
evidence of target engagement at 14−28 h, then Cohort 2 may explore time points 
between 30 min and 28 h after a 1,000 µg dose. 

If significant target engagement is observed at 30 min and at 14−28 h, then Cohort 2 
may explore target engagement at time points between 30 min and 28 h after a dose 
lower than 1,000 µg.
A decision-making flowchart is shown in Appendix 10.
Cohort 2 may be open-label, in which case up to 10 participants may receive single doses 
of GSK3008348 in an open-label manner.  If Cohort 1 data suggests that including a 
placebo control would be beneficial, for example for safety reasons, Cohort 2 will be 
carried out in a double-blind (sponsor unblind) fashion, with up to 14 participants 
randomised 5:2 to receive GSK3008348 or placebo. 
The dose level will be 1,000 µg or lower, and may be changed at any time depending on 
previous or emerging data. Participants may receive a lower dose in dosing period 2 
compared to dosing period 1.  The length of post-dose safety monitoring in the clinic will 
be decided based on previous or emerging data, but participants will be monitored for at 
least 8 h post-first dose.  
Participants will have 2 planned dosing periods, both on an outpatient basis, with an 
additional visit for baseline imaging, as follows.

Dosing period 1:  participants will have pre-dose health assessments and a 
pharmacogenetics sample at the clinical unit on the morning of Day 1.  They will 
remain in the clinical unit for at least 8 h after receiving their nebulised dose for 
safety observations, and then return to the clinical unit on Day 2.  Safety assessments 
will be done, and PK and exploratory biomarker samples taken.  

Baseline PET scan and HRCT scan at least 7 days after the first dose, and a maximum 
of 14 days before the first post-dose PET scan. 

Dosing period 2:  participants will attend the clinical unit for health assessments 
before dosing, on Day 1 or Day −1.  If participants pass the health assessments, they 
will attend the imaging unit, have their dose administered, and have up to 2 post-dose 
PET scans.  Alternatively, dosing may take place at the clinical unit before the patient 
is transferred to the imaging unit for their PET scan, depending on the PET scan 
timing; however, the participant must be observed for at least 4 h post-dose without 
changing location.  The timing of the post-dose PET scans will be determined based 
on emerging study data.  Doses will be separated by a washout of between 7 and 
28 days. 
5.1.3.
Changes to Cohorts 1 or 2
Participants in Cohorts 1 and 2 will have 2 planned dosing periods.  However, if a PET 
scan cannot be performed (e.g. because of technical issues, PET ligand synthesis 
radiochemistry failure, or because the participant cannot be scanned for safety reasons), 
participants may repeat the visit or dosing period, and repeat procedures in order to 


2016N291965_02

204715
24
obtain a full dataset for each endpoint.  Participants may be administered an additional 
dose of GSK3008348 after a 7-day washout, such that they receive a maximum of 
3 single doses in total during the study.  Participants will not, however, be administered 
an additional dose of [18F]-FBA-A20FMDV2; they will receive a maximum of 3 doses of 
the radiotracer during the study.  
If a participant experiences unexpected and/or potentially serious side effects after their
first or second dose, they will be referred to the clinical site investigator for assessment 
and ongoing care. That may include admission to a clinical bed, if deemed appropriate 
by the investigator, as per routine clinical practice. 
5.2.
Number of Participants
It is anticipated that up to 21 participants will be randomised, as follows. 

Cohort 1 – 7 participants will be randomised. (7 participants will be randomised, 
dosed and considered complete when PET data at 30 min post-dose has been 
collected)

Cohort 2 – up to 10 participants may be randomised if an open-label design is chosen; 
or up to 14 participants may be randomised if a double-blind design is chosen. 
Refer to Section 10.2 for definitions of participants who will be considered evaluable and 
therefore included in the analyses. 
If participants prematurely discontinue the study, additional replacement participants may
be recruited and randomised to the same treatment at the discretion of the Sponsor in 
consultation with the investigator.  Replacement participants will start the study at dosing 
period 1, in order to establish tolerability of the study medication before entering the PET 
scanning dosing period. 
5.3.
Participant and Study Completion
A participant is considered to have completed the study if he/she has completed all 
phases of the study, including the baseline PET scan, at least 1 post-dose PET scan, and 
the last follow-up visit.  
The end of the study is defined as the date of the last visit of the last participant in the 
study.
5.4.
Scientific Rationale for Study Design

Cohort 1 includes a placebo control to allow assessment of safety and tolerability, as 
reporting of adverse events in patients receiving placebo will facilitate the 
differentiation between ‘disease’ and ‘intervention’ adverse events.   

Cohort 1 will be conducted in a double-blind (sponsor unblind) fashion. Safety and 
PK data reviews will be conducted without treatment group assignment or subject 
numbers, so that the investigators and data review team remain blinded. The

25
statistician will perform an unblinded review of PET data as part of the pre-planned 
interim analysis, to allow appropriate decision-making.  The sponsor (including the 
medical monitor) may also undertake separate in-stream review of unblinded data to 
help determine the most appropriate response to emerging data.  

The number of patients to be enrolled in Cohort 1 (7 participants) is based on the 
probability of detecting a change in vβ6 internalisation at approximately 30 min
post-dose compared to pre-dose of 6% or greater, as measured by the uptake of [18F]-
FBA-A20FMDV2 in the lungs reported as the volume of distribution [VT]. This
predetermined change is equivalent to approximately half the difference in [18F]-
FBA-A20FMDV2 PET signal observed between healthy volunteers and IPF patients 
in a previous study RES116235. If GSK3008348 cannot achieve that reduction in 
vβ6-associated PET signal and the endpoint variability is as expected, then the study 
will end.

The design for Cohort 2 will be defined following completion of Cohort 1, to ensure 
the most informative doses of GSK3008348 are selected and the PET scans are timed 
appropriately.  Cohort 2 data may be reviewed in-stream and the design of Cohort 2 
adjusted to maximise the value of the data obtained.  The aim is to assess target 
engagement while exposing the smallest possible number of patients to ionising 
radiation from the PET procedure.
5.5.
Dose Justification
The first-time-in-human study 200262 showed that single nebulised doses of 1–3,000 μg 
GSK3008348 were well tolerated in healthy participants, with PK exposures within the 
defined limits set by the protocol.
The 1,000 μg dose was selected for this study as the preliminary geometric mean Cmax
and AUC(inf) observed in healthy volunteers in study 200262 provided 22- and 11-fold 
margins, respectively, over the systemic exposures observed in the most sensitive 
preclinical species (Day 1 exposures from the Rat 1 month good laboratory practice
[GLP] study at the 12000 µg/kg/day dose level; the no effect level for systemic toxicity). 
Additionally, the 1,000 μg dose maintains adequate safety coverage over the NOAEL 
based on the deposited lung dose (36-fold over the rat and 26-fold over the dog, 1 month 
GLP toxicity studies).  The proposed dose therefore allows significant safety margins in 
the event that systemic exposure is greater in IPF patients than in healthy volunteers.
In addition, the observed PK in study 200262 demonstrated peak systemic unbound 
concentrations significantly in excess of the in vitro Kd for GSK3008348. Given that 
GSK3008348 is inhaled, it is reasonable to assume that lung tissue exposures were at 
least as high as those observed in plasma and so are expected to engage with vβ6 to a 
significant extent.

Dose Modification
The proposed dose for Cohorts 1 and 2 is 1,000 µg GSK3008348. The dose may be 
decreased in Cohort 2 at any time, depending on previous or emerging data.  The decision 
will be made by the data review team based on available preliminary safety, tolerability, 
PK and PET data obtained from preceding participants. The dose will not be increased 
above 1,000 µg. 
7.3.
Method of Treatment Assignment
Participants will be randomised to a subject number in accordance with the randomisation 
schedule generated by GSK Clinical Statistics before the study start, using validated 
internal software (RANDALL NG).  Each participant in Cohort 1 will be randomised 5:2 
to receive either GSK3008348 or placebo.  Participants in Cohort 2 will receive 
GSK3008348 in an open-label manner, unless it is decided that a placebo control would 
be beneficial, in which case participants will be randomised 5:2 to receive either 
GSK3008348 or placebo. 
All participants will be centrally randomised using an Interactive Voice/Web Response 
System (IVRS/IWRS).  Before the study is initiated, the telephone number or log in 
information and directions will be provided to each site.  
Study treatment for both dosing periods will be dispensed by appropriately trained 
pharmacy staff. 
Returned study treatment should not be re-dispensed to the participants. 
7.4.
Blinding
Cohort 1 will be double-blind (sponsor unblind).  Cohort 2 may be open-label, or may be 
double-blind (sponsor unblind) if required.  For double-blind cohorts, the following will 
apply.


2016N291965_02
CONFIDENTIAL
204715
31
An unblinded monitor, if required, and in the event of a Quality Assurance audit, the 
auditors, will be allowed access to unblinded study treatment records at the sites to verify 
that randomisation and dispensing has been done accurately. 
The IVRS/IWRS will be programmed with blind-breaking instructions.  The blind may 
be broken by the investigator or treating physician in the case of an emergency, or if, in 
the opinion of the investigator, it is in the participant’s best interest for the investigator to 
know the study treatment assignment.  The investigator is encouraged to discuss with the 
GSK Medical Monitor or appropriate GSK study personnel before the blind is broken.  If 
GSK is not notified before the blind is broken, they must be notified as soon as possible 
after breaking the blind.  The date and reason that the blind was broken must be recorded 
in the source documentation and electronic case report form (eCRF), as applicable. 
A participant may continue in the study if their treatment assignment is unblinded, at the 
discretion of the Medical Monitor.  If a participant is withdrawn after their treatment code 
is unblinded by the investigator or treating physician, the primary reason for 
discontinuation (the event or condition which led to the unblinding) will be recorded in 
the eCRF.
GSK’s Global Clinical Safety and Pharmacovigilance (GCSP) staff may unblind the 
treatment assignment for any participant with an SAE. If the SAE requires that an
expedited regulatory report be sent to one or more regulatory agencies, a copy of the 
report, identifying the participant’s treatment assignment, may be sent to investigators in
accordance with local regulations and/or GSK policy.
For an open-label cohort, all participants will be randomised to active study treatment. 
7.5.
Preparation/Handling/Storage/Accountability

The investigator or designee must confirm appropriate temperature conditions have 
been maintained during transit for all study treatment received and any discrepancies 
are reported and resolved before use of the study treatment.

Only participants enrolled in the study may receive study treatment and only 
authorised site staff may supply or administer study treatment.  All study treatments 
must be stored in a secure, environmentally controlled, and monitored (manual or 
automated) area in accordance with the labelled storage conditions with access 
limited to the investigator and authorised site staff.

The investigator is responsible for study treatment accountability, reconciliation, and 
record maintenance (ie, receipt, reconciliation, and final disposition records).

Further guidance and information for the final disposition of unused study treatment 
are provided in the Study Reference Manual (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.


2016N291965_02
CONFIDENTIAL
204715
32

A Material Safety Data Sheet (MSDS)/equivalent document describing occupational 
hazards and recommended handling precautions either will be provided to the 
investigator, where this is required by local laws, or is available upon request from 
GSK.
7.6.
Treatment Compliance
Participants will be dosed at the sites, and will receive study treatment directly from the 
investigator or designee, under medical supervision.  The date and time of each dose 
administered in the clinic will be recorded in the source documents.  The dose of study 
treatment and study participant identification will be confirmed at the time of dosing by a 
member of the study site staff other than the person administering the study treatment. 
7.7.
Concomitant Therapy
Any medication or vaccine (including over-the-counter or prescription medicines, 
vitamins, and/or herbal supplements) that the participant is receiving at the time of 
enrolment or receives during the study must be recorded along with:

reason for use

dates of administration including start and end dates

dosage information including dose and frequency
Participants must not be taking pirfenidone or nintedanib, or must abstain from taking 
pirfenidone or nintedanib within 30 days before their first dose of study treatment until 
completion of the follow-up visit. 
There is an unknown risk of interaction with OAT substrates with a narrow therapeutic 
index (eg methotrexate and tenofovir).  Therefore, participants must abstain from taking 
these agents within 7 days or 5 half-lives (whichever is longer) before their first dose of 
study treatment until completion of the follow-up visit. Participants must also abstain 
from taking vitamins and dietary or herbal supplements for the same period, unless, in the 
opinion of the investigator and sponsor, the supplement will not interfere with the study 
medication. 
Other concomitant medication, including paracetamol at doses of 4 grams/day, is
permitted for use any time during the study.  The Medical Monitor should be contacted if 
there are any questions regarding concomitant or prior therapy.
7.8.
Treatment after the End of the Study
Participants will not receive any additional treatment from GSK after completion of the 
study.  The investigators are responsible for ensuring that consideration has been given to 
the post-study care of the participant’s medical condition.

Discontinuation of Study Treatment
8.1.1.
Liver Chemistry Stopping Criteria
Liver chemistry stopping and increased monitoring criteria have been designed to 
assure participant safety and evaluate liver event etiology (in alignment with the Food 
and Drug Administration [FDA] premarketing clinical liver safety guidance). These 
protocol guidelines are in alignment with FDA premarketing clinical liver safety 
guidance: 
http://www.fda.gov/downloads/Drugs/GuidanceComplianceRegulatoryInformation/Guid
ances/UCM174090.pdf.
Discontinuation of study treatment for abnormal liver tests should be considered by the 
investigator when a participant meets one of the conditions outlined in the algorithm or if 
the investigator believes that it is in the best interest of the participant.

Appendix 7.  
8.1.2.
QTc Stopping Criteria
A participant who meets either of the bulleted criteria below will be withdrawn from the 
study:

QTc > 500 msec OR Uncorrected QT > 600 msec

Change from baseline of QTc > 60 msec

For patients with underlying bundle branch block, follow the discontinuation criteria 
listed below:
Baseline QTc with Bundle Branch Block
Discontinuation QTc with Bundle 
Branch Block
< 450 msec
> 500 msec
450 – 480 msec
≥ 530 msec

The same QT correction formula must be used for each individual participant to 
determine eligibility for and discontinuation from the study.  This formula may not 
be changed or substituted once the participant has been enrolled.

For example, if a participant is eligible for the protocol based on QTcF, then 
QTcF must be used for discontinuation of this individual participant as well.

Once the QT correction formula has been chosen for a participant’s eligibility, 
the same formula must continue to be used for that participant for all QTc data 
being collected for data analysis.  Safety ECGs and other non-protocol specified 
ECGs are an exception.  

The QTc should be based on averaged QTc values of triplicate electrocardiograms 
obtained over a brief (e.g., 5-10 minute) recording period.  
8.1.3.
Individual Adverse Event Stopping Criteria
A participant will be withdrawn from the study if they experience:
1. An SAE that is at least possibly related to the study treatment 
2. An IPF exacerbation, upper or lower respiratory tract infection or other systemic 
infection
3. A clinically significant change in a laboratory value or vital sign
4. Failure to recover from an adverse event
A participant can be discontinued from therapy if the investigator decides that the patient 
should be withdrawn. 
Participants who are withdrawn will complete the follow-up visit, as described in the 
SoA.
8.2.
Withdrawal from the Study

A participant may withdraw from the study at any time at his/her own request, or 
may be withdrawn at any time at the discretion of the investigator for safety, 
behavioural, compliance or administrative reasons.

If the participant withdraws consent for disclosure of future information, the sponsor 
may retain and continue to use any data collected before such a withdrawal of 
consent.


2016N291965_02
CONFIDENTIAL
204715
35

If a participant withdraws from the study, he/she may request destruction of any 
samples taken and not tested, and the investigator must document this in the site 
study records.

Refer to the SoA for data to be collected at follow-up for evaluations that need to be 
completed.
8.3.
Lost to Follow Up
A participant will be considered lost to follow-up if he or she repeatedly fails to return for 
scheduled visits and is unable to be contacted by the study site. 
The following actions must be taken if a participant fails to return to the clinic for a 
required study visit:

The site must attempt to contact the participant and reschedule the missed visit as 
soon as possible and counsel the participant on the importance of maintaining the 
assigned visit schedule and ascertain whether or not the participant wishes to and/or 
should continue in the study.

Before a participant is deemed lost to follow up, the investigator or designee must 
make every effort to regain contact with the participant (where possible, 3 telephone 
calls and, if necessary, a certified letter to the participant’s last known mailing 
address or local equivalent methods). These contact attempts should be documented 
in the participant’s medical record.

Should the participant continue to be unreachable, he/she will be considered to have 
withdrawn from the study with a primary reason of lost to follow-up. 
9.
STUDY ASSESSMENTS AND PROCEDURES

Study procedures and their timing are summarized in the SoA. All post-dose time 
points are relevant to the start of nebulisation. 

Protocol waivers or exemptions are not allowed.

Immediate safety concerns should be discussed with the sponsor immediately upon 
occurrence or awareness to determine if the participant should continue or 
discontinue study treatment.

Adherence to the study design requirements, including those specified in the SoA, is 
essential and required for study conduct.

All screening evaluations must be completed and reviewed to confirm that potential 
participants meet all eligibility criteria. The investigator will maintain a screening 
log to record details of all participants screened and to confirm eligibility or record 
reasons for screening failure, as applicable. 

Procedures conducted as part of the participant’s routine clinical management (eg, 
blood count) and obtained before signing of ICF may be utilized for screening or 
baseline purposes provided the procedure met the protocol-specified criteria and was
performed within the time frame defined in the SoA.


The maximum amount of blood collected from each participant over the duration of 
the study, including any extra assessments that may be required, will not exceed 
500 mL. 

Repeat or unscheduled samples may be taken for safety reasons or for technical 
issues with the samples.
9.1.
Efficacy Assessments
Not applicable. 
9.2.
Adverse Events
The definitions of an AE or SAE can be found in Appendix 4.
The investigator and any designees are responsible for detecting, documenting, and 
reporting events that meet the definition of an AE or SAE and remain responsible for 
following up AEs that are serious, considered related to the study treatment or the study,
or that caused the participant to discontinue the study (see Section 8). 
9.2.1.
Time Period and Frequency for Collecting AE and SAE 
Information

All SAEs will be collected from the first dose of study treatment until the follow-up 
visit at the time points specified in the SoA (Section 2).

All AEs will be collected from the first dose of study treatment until the follow-up 
visit at the time points specified in the SoA (Section 2).

Medical occurrences that begin before the first dose of study treatment but after 
obtaining informed consent will be recorded on the Medical History/Current Medical 
Conditions section of the eCRF not the AE section.

All SAEs will be recorded and reported to the sponsor or designee within 24 hours, 
as indicated in Appendix 4. The investigator will submit any updated SAE data to the 
sponsor within 24 hours of it being available.

Investigators are not obligated to actively seek AEs or SAEs in former study 
participants. However, if the investigator learns of any SAE, including a death, at 
any time after a participant has been discharged from the study, and he/she considers 
the event to be reasonably related to the study treatment or study participation, the 
investigator must promptly notify the sponsor.

The method of recording, evaluating, and assessing causality of AEs and SAEs and 
the procedures for completing and transmitting SAE reports are provided in 
Appendix 4.
9.2.2.
Method of Detecting AEs and SAEs
Care will be taken not to introduce bias when detecting AE and/or SAE. Open-ended and 
non-leading verbal questioning of the participant is the preferred method to inquire about 
AE occurrence.

CONFIDENTIAL
204715
37
9.2.3.
Follow-up of AEs and SAEs
After the initial AE/SAE report, the investigator is required to proactively follow each 
participant at subsequent visits/contacts. All SAEs will be followed until the event is 
resolved, stabilized, otherwise explained, or the participant is lost to follow-up (as 
defined in Section 8.3). Further information on follow-up procedures is given in 
Appendix 4.
9.2.4.
Regulatory Reporting Requirements for SAEs

Prompt notification by the investigator to the sponsor of a SAE is essential so that 
legal obligations and ethical responsibilities towards the safety of participants and 
the safety of a study treatment under clinical investigation are met. 

The sponsor has a legal responsibility to notify both the local regulatory authority 
and other regulatory agencies about the safety of a study treatment under clinical 
investigation. The sponsor will comply with country-specific regulatory 
requirements relating to safety reporting to the regulatory authority, Institutional 
Review Boards (IRB)/Independent Ethics Committees (IEC), and investigators.

Investigator safety reports must be prepared for suspected unexpected serious 
adverse reactions (SUSAR) according to local regulatory requirements and sponsor 
policy and forwarded to investigators as necessary.

An investigator who receives an investigator safety report describing a SAE or other 
specific safety information eg, summary or listing of SAE) from the sponsor will 
review and then file it along with the Investigator’s Brochure and will notify the 
IRB/IEC, if appropriate according to local requirements.
9.2.5.
Cardiovascular and Death Events
For any cardiovascular events and all deaths, whether or not they are considered SAEs, 
specific Cardiovascular (CV) and Death sections of the eCRF will be required to be 
completed. These sections include questions regarding cardiovascular (including sudden 
cardiac death) and non-cardiovascular death. 
The CV eCRFs are presented as queries in response to reporting of certain CV Medical 
dictionary for regulatory activities (MedDRA) terms. The CV information should be 
recorded in the specific cardiovascular section of the CRF within one week of receipt of a 
CV Event data query prompting its completion. 
The Death eCRF is provided immediately after the occurrence or outcome of death is 
reported. Initial and follow-up reports regarding death must be completed within one 
week of when the death is reported.
9.2.6.
Pregnancy

Details of all pregnancies in female participants and, if indicated, female partners of 
male participants will be collected after the start of study treatment and until the 
follow-up visit.


If a pregnancy is reported, the investigator should inform GSK within 24 hours of
learning of the pregnancy and should follow the procedures outlined in Appendix 5.

Abnormal pregnancy outcomes (eg, spontaneous abortion, fetal death, stillbirth, 
congenital anomalies, ectopic pregnancy) are considered SAE.
9.3.
Treatment of Overdose
For this study, any dose of GSK3008348 greater than 1,000 µg within a 24-hour time 
period will be considered an overdose.
GSK does not recommend specific treatment for an overdose.
In the event of an overdose, the investigator should:
21. Contact the Medical Monitor immediately.
22. Closely monitor the participant for AE/SAE and laboratory abnormalities until 
GSK3008348 can no longer be detected systemically (at least 2 days).
23. Obtain a plasma sample for PK analysis within 2 days from the date of the last dose 
of study treatment if requested by the Medical Monitor (determined on a case-by-
case basis).
24. Document the quantity of the excess dose as well as the duration of the overdosing in 
the eCRF.
Decisions regarding dose interruptions or modifications will be made by the investigator 
in consultation with the Medical Monitor based on the clinical evaluation of the 
participant.
9.4.
Safety Assessments
Planned time points for all safety assessments are provided in the SoA.
9.4.1.
Physical Examinations

A complete physical examination will include, at a minimum, assessments of the 
skin, cardiovascular, respiratory, gastrointestinal and neurological systems, and the 
oropharynx. Height and weight will also be measured and recorded.

A brief physical examination will include, at a minimum, assessments of the skin, 
lungs, oropharynx, cardiovascular system, and abdomen (liver and spleen).

Investigators should pay special attention to clinical signs related to previous serious 
illnesses.
9.4.2.

automated device. Manual techniques will be used only if an automated device is not 
available.

Vital signs will be measured in a semi-supine position after 5 minutes rest. 
9.4.3.
Peripheral capillary oxygen saturation

Peripheral capillary oxygen saturation (SpO2) levels will be continuously monitored 
with a completely automated device. 
9.4.4.
Electrocardiograms

Triplicate 12-lead ECG will be obtained and recorded in the eCRF as outlined in the 
SoA using an ECG machine that automatically calculates the heart rate and measures 
PR, QRS, QT, and QTcF intervals. Refer to Section 8.1.2 for QTc withdrawal 
criteria and additional QTc readings that may be necessary.
9.4.5.
Clinical Safety Laboratory Assessments

Refer to Appendix 2 for the list of clinical laboratory tests to be performed and to the 
SoA for the timing and frequency. 

The investigator must review the laboratory report, document this review, and record 
any clinically relevant changes occurring during the study in the AE section of the 
eCRF. The laboratory reports must be filed with the source documents. Clinically 
significant abnormal laboratory findings are those which are not associated with the 
underlying disease, unless judged by the investigator to be more severe than 
expected for the participant's condition.

All laboratory tests with values considered clinically significantly abnormal during 
participation in the study should be repeated until the values return to normal or 
baseline or are no longer considered significantly abnormal by the investigator or 
medical monitor. 

If such values do not return to normal/baseline within a period of time judged 
reasonable by the investigator, the aetiology should be identified and the sponsor 
notified.

All protocol-required laboratory assessments, as defined in Appendix 2, must be 
conducted in accordance with the SRM and the SoA.

If laboratory values from non-protocol specified laboratory assessments performed at 
the institution’s local laboratory require a change in participant management or are 
considered clinically significant by the investigator (eg, SAE or AE or dose 
modification), then the results must be recorded in the eCRF.
9.4.6 Lung Function Tests

Spirometry measurements will be obtained using standard spirometry equipment 
available at sites, to include FEV1 and FVC.

DLCO will be measured according to local procedures.


2016N291965_02
CONFIDENTIAL
204715
40

For calculating % predicted FEV1, FVC and DLCO, the Quanjer 2012 
calculation is to be used.

All subjects will have spirometry and DLCO performed at Screening to assess 
eligibility and at time points as described in the time and events table.

Participants must perform 3 acceptable blows, all within 5% of each other. The 
difference between the highest FEV1 and the second highest should be within 
150 mL. A maximum of 8 attempts can be made for each time point.

Only the highest FEV1 and FVC measurements should be recorded. 

At each time point, measurements of FEV1 and FVC should be compared to 
baseline. Any clinically significant decreases in either measurements compared 
to baseline, as judged by the investigator, will be recorded as an AE.
9.5.
Pharmacokinetics

Whole blood samples of approximately 2 mL will be collected for measurement of 
plasma concentrations of GSK3008348 as specified in the SoA.  A maximum of 
5 additional samples may be collected at additional time points during the study if 
warranted and agreed upon between the investigator and the sponsor. Instructions for 
the collection and handling of biological samples will be provided in the SRM.  The 
actual date and time (24 hour clock time) of each sample will be recorded.

Samples will be used to evaluate the PK of GSK3008348.  Samples collected for 
analyses of GSK3008348 plasma concentration may also be used to evaluate safety or 
efficacy aspects related to concerns arising during or after the study.

Genetic analyses will not be performed on these plasma samples.  Participant 
confidentiality will be maintained. 

Once the plasma has been analyzed for GSK3008348, any remaining plasma may be 
analysed for other compound-related metabolites and the results reported under a 
separate protocol.

Urine samples will be analysed qualitatively for drug-related components and the 
results reported under a separate Platform Technology and Science-Product 
Development and Supply, GlaxoSmithKline study.
Drug concentration information that would unblind the study will not be reported to 
investigative sites or blinded personnel until the study has been unblinded.
9.6.
Positron Emission Tomography (PET)
Before each PET scan, participants will have a low dose CT scan to provide data to 
enable correction of the PET data for tissue attenuation.  [18F]-FBA-A20FMVD2 will 
then be injected into a cubital or forearm vein through an intravenous cannula, and 
emission data acquired for up to 90 minutes.  One rest period will be permitted during the 
scan, if required. 


2016N291965_02
CONFIDENTIAL
204715
41
An additional venous cannula in a cubital or forearm vein will be used to collect blood 
samples throughout the PET scan for quantification of the total and unmetabolised [18F]-
FBA-A20FMDV2-related radioactivity in whole blood and plasma.  The data will be 
used to derive an input function for the analysis of emission PET data.  The cannula may 
be flushed with saline to keep it patent, if required; HepSal will not be used.  At the end 
of the scanning day, the cannula will be removed.  
At the baseline visit only, an HRCT scan will also be performed for anatomical 
localisation.
In the event of a problem that prevents the PET scan going ahead after the study 
treatment has been administered, such as a quality control failure of the synthesised 
tracer, the scan may be rescheduled.  An additional dose of study treatment may be 
administered to the participant if required, at the discretion of the investigator and GSK 
Medical Monitor, as described in Section 5.1.3.
9.7.
Genetics
A 6 mL blood sample for deoxyribonucleic acid (DNA) isolation will be collected from 
participants who have consented to participate in the genetics analysis component of the 
study. Participation is optional. Participants who do not wish to participate in the genetic 
research may still participate in the study.
In the event of DNA extraction failure, a replacement genetic blood sample may be 
requested from the participant. Signed informed consent will be required to obtain a 
replacement sample unless it was included in the original consent.
See Appendix 6 for information regarding genetic research. Details on processes for 
collection and shipment and destruction of these samples can be found in the SRM.
9.8.
Biomarkers
Blood samples will be collected during this study and may be used for the purposes of
measuring novel biomarkers to identify factors that may influence IPF, and/or medically
related conditions, as well as the biological and clinical responses to GSK3008348. If
relevant, this approach will be extended to include the identification of biomarkers
associated with adverse events.  These analyses are exploratory in nature, and will be 
reported separately from the results of the clinical trial. 
Samples will be collected at the timepoints indicated in the SoA. The actual date and
time of each blood sample collection will be recorded. The timing of the collections may
be adjusted on the basis of emerging PK or pharmacodynamic (PD) data from this study 
or other new information in order to ensure optimal evaluation of the endpoints.
Novel candidate biomarkers and subsequently discovered biomarkers of the biological
response associated with IPF or medically related conditions and/or the action of study
treatment may be identified by the potential application of: 

Ribonucleic acid (RNA) transcriptome analysis of blood samples.


2016N291965_02
CONFIDENTIAL
204715
42

Measurement of the levels of a subset of RNA species in blood.

Proteome analysis in plasma and blood samples.

Measurement of the levels of a subset of proteins in plasma and blood samples 
which may include but are not limited to chemokine (C-C  motif) ligand 18 
(CCL18) [Prasse, 2009] and collagen degradation biomarkers [Jenkins, 2015].
Samples may be used for research to develop methods, assays, prognostics and/or 
companion diagnostics related to αvβ6, IPF disease processes, pathways associated with 
IPF and/or mechanism of action of GSK3008348.
All samples will be retained for a maximum of 15 years after the last participant
completes the trial.
9.9.
Immunogenicity Assessments
Serum samples will be analysed for the presence of anti-[18F]-FBA-A20FMDV2 
antibodies. Approximately 7 mL of blood will be collected into serum separator (SST) 
tubes (no anti-coagulant) at the timepoints indicated SoA.

STATISTICAL CONSIDERATIONS
10.1.
Sample Size Determination
This study is designed to assess the level of receptor engagement as measured by the 
effect of nebulised GSK3008348 on the v6-associated PET signal (VT). The PET data 
from the 5 participants in Cohort 1 receiving GSK3008348 will be used.  This sample 
size has been chosen based on considerations given to: a) the probability of declaring a 
successful study for reductions in v6-associated PET signal deemed to be 
representative of the expected receptor engagement activity, and b) the within-subject 
variability of the PET signal.
The chosen study success criteria is defined as Prob (θ < 0 | Study Data, Prior (θ)) ≥80%, 
where θ is the unknown true logarithm of the ratio of v6-associated PET signal post-
dose / pre-dose in patients receiving GSK3008348, and the prior distribution for θ is non-
informative. Assuming the within-subject standard deviation is as previously observed in 
study RES116235 (within-subject standard deviation following two PET scans was 
estimated to be 0.15, 95% CI [0.099, 0.34]), consideration was given to the probability of 
achieving the study success criteria for a range of true reductions in v6-associated PET 
signal with GSK3008348. In addition, the minimum detectable effect (MDE), i.e., the 
minimum observed reduction in v6-associated PET signal leading to the success

204715
43
criteria being achieved, was also derived. In particular, if the true reduction in v6-
associated PET signal is 14% then there is 86% probability of achieving the above 
success criteria, and the MDE is a 6.2% reduction in v6-associated PET signal. 
10.2.
Populations for Analyses
For purposes of analysis, the following populations are defined:
Population
Description
All participants
All participants who are screened and for whom a record exists on 
the study database.
Enrolled 
All participants who are screened and enrolled into the study.
Intent-To-Treat (ITT)
All randomised participants who receive at least one dose of study 
treatment. This population will be based on the treatment they 
actually received. 
Per-Protocol
All participants in the ITT population who comply with the protocol 
and that have at least one evaluable PET measurement post 
baseline. 
Pharmacokinetic

Statistical Analyses
10.3.1.
Pharmacodynamic Analyses
Endpoint
Statistical Analysis Methods
Volume of 
distribution [VT] in 
whole lung, not 
corrected for air 
volume
The logarithm of the v6-associated PET signal as measured by VT
will be analysed assuming that it follows a normal distribution. The 
mean or median signal level pre- and post-dose, as appropriate 
depending on the posterior distribution, along with the median 
difference post-dose – pre-dose, will be estimated and the 
corresponding 95% credible intervals will be produced. The posterior 
probability that the true difference in the logarithm of v6-associated 
PET signal post-dose vs pre-dose is less than 0 will be calculated. 
Non-informative priors will be used for all the parameters in the 
statistical model.
Secondary
Will be described in the reporting and analysis plan (RAP)
Exploratory
Will be described in the RAP

10.3.2.
Safety Analyses
All safety analyses will be performed on the ITT Population. Safety data will be 
presented in tabular and/or graphical format and summarised descriptively according to 
GSK’s Integrated Data Standards Library (IDSL) standards.
10.3.3.
Pharmacokinetic analyses
Plasma concentration-time data of GSK3008348 will be displayed in listings, summary 
tables and/or graphically.  Summary data will use nominal/planned sample times, listings 
will display planned and actual times.  Plasma concentration-time data may be used to 
derive PK parameters (such as AUC and Cmax) using standard non-compartmental 
analysis according to current working practices and using Phoenix WNL, or other 
currently validated software.  All calculations of non-compartmental parameters will be 
based on actual sampling times.
Additionally, plasma concentration-time data may be used to derive population PK 
parameters/models using NONMEM or other currently validated software.  Any 
population PK analysis will be presented separately from the main clinical study report 
(CSR).
Statistical analyses of the PK parameter data will be the responsibility of Clinical 
Statistics, GlaxoSmithKline.
10.3.4.
Other Analyses
Exploratory PD and biomarker analyses will be described in the RAP, and will be 
presented separately from the main CSR. 
10.3.5.
Interim Analyses
An interim analysis will be performed for futility or sample size re-estimation based on 
the variability of the PET signal (VT) and the level of receptor engagement at the end of 
Cohort 1 and prior to the start of Cohort 2. The PET data from the 5 participants in 
Cohort 1 receiving GSK3008348 will be used. The logarithm of the v6-associated PET 
signal as measured by VT will be analysed assuming that it follows a normal distribution. 
10.3.5.1.
Interim Analysis for Futility
Assuming that the variability is as anticipated, if the posterior probability Prob (θ < 0 | 
Study Data, Prior (θ)) < 80%, where θ is the unknown true logarithm of the ratio of 
v6-associated PET signal post-dose / pre-dose in patients receiving 1,000 µg
GSK3008348 in Cohort 1, and the prior distribution for θ is non-informative, then the 
study will stop for futility. If the study is stopped at the end of Cohort 1, then Cohort 2 
will not proceed.

10.3.5.2.
Interim Analysis for Sample Size Re-estimation
If the variability in VT is higher than expected, then sample size re-estimation will be 
performed and additional participants receiving 1,000 µg GSK3008348 will be recruited 
into Cohort 2. Sample size re-estimation will be primarily based on the posterior 
predictive distribution of the data given the information collected at the interim, and the 
predictive probability of end-of-study success. This probability will be calculated for a 
range of sample sizes up to a maximum of 10 additional participants receiving 1,000 µg 
GSK3008348 in Cohort 2.
Further details of the interim analysis will be provided in the RAP.

Appendix 4: Adverse Events: Definitions and Procedures for 
Recording, Evaluating, Follow-up, and Reporting
Definition of AE
AE Definition

An AE is any untoward medical occurrence in a clinical study participant, temporally 
associated with the use of a study treatment, whether or not considered related to the 
study treatment.

NOTE: An AE can therefore be any unfavorable and unintended sign (including an 
abnormal laboratory finding), symptom, or disease (new or exacerbated) temporally 
associated with the use of a study treatment.
Events Meeting the AE Definition 

Any abnormal laboratory test results (hematology, clinical chemistry, or urinalysis) 
or other safety assessments (eg, ECG, radiological scans, vital signs measurements), 
including those that worsen from baseline, considered clinically significant in the 
medical and scientific judgment of the investigator (ie, not related to progression of 
underlying disease).

Exacerbation of a chronic or intermittent pre-existing condition including either an 
increase in frequency and/or intensity of the condition.

New conditions detected or diagnosed after study treatment administration even 
though it may have been present before the start of the study.

Signs, symptoms, or the clinical sequelae of a suspected drug-drug interaction.

Signs, symptoms, or the clinical sequelae of a suspected overdose of either study 
treatment or a concomitant medication. Overdose per se will not be reported as an 
AE/SAE unless it is an intentional overdose taken with possible suicidal/self-
harming intent. Such overdoses should be reported regardless of sequelae.
Events NOT Meeting the AE Definition 

Any clinically significant abnormal laboratory findings or other abnormal safety 
assessments which are associated with the underlying disease, unless judged by the 
investigator to be more severe than expected for the participant’s condition.

The disease/disorder being studied or expected progression, signs, or symptoms of 
the disease/disorder being studied, unless more severe than expected for the 
participant’s condition.

Medical or surgical procedure (eg, endoscopy, appendectomy): the condition that 


2016N291965_02
CONFIDENTIAL
204715
57
leads to the procedure is the AE.

Situations in which an untoward medical occurrence did not occur (social and/or 
convenience admission to a hospital).

Anticipated day-to-day fluctuations of pre-existing disease(s) or condition(s) present 
or detected at the start of the study that do not worsen.
Definition of SAE
If an event is not an AE per definition above, then it cannot be an SAE even if serious 
conditions are met (eg, hospitalization for signs/symptoms of the disease under study, 
death due to progression of disease).
A SAE is defined as any untoward medical occurrence that, at any dose:
a.
Results in death
b.
Is life-threatening
The term 'life-threatening' in the definition of 'serious' refers to an event in which the 
participant was at risk of death at the time of the event. It does not refer to an event, 
which hypothetically might have caused death, if it were more severe.
c.
Requires inpatient hospitalization or prolongation of existing hospitalization
In general, hospitalization signifies that the participant has been detained (usually 
involving at least an overnight stay) at the hospital or emergency ward for observation 
and/or treatment that would not have been appropriate in the physician’s office or 
outpatient setting. Complications that occur during hospitalization are AE. If a 
complication prolongs hospitalization or fulfills any other serious criteria, the event is 
serious. When in doubt as to whether “hospitalization” occurred or was necessary, the AE 
should be considered serious.
Hospitalization for elective treatment of a pre-existing condition that did not worsen from 
baseline is not considered an AE.
d.
Results in persistent disability/incapacity

The term disability means a substantial disruption of a person’s ability to conduct 
normal life functions.

This definition is not intended to include experiences of relatively minor medical 
significance such as uncomplicated headache, nausea, vomiting, diarrhea, influenza, 
and accidental trauma (eg, sprained ankle) which may interfere with or prevent 
everyday life functions but do not constitute a substantial disruption.
e.
Is a congenital anomaly/birth defect
f.
Other situations:

Medical or scientific judgment should be exercised in deciding whether SAE 
reporting is appropriate in other situations such as important medical events that may 


2016N291965_02
CONFIDENTIAL
204715
58
not be immediately life-threatening or result in death or hospitalization but may 
jeopardize the participant or may require medical or surgical intervention to prevent 
one of the other outcomes listed in the above definition. These events should usually 
be considered serious.
Examples of such events include invasive or malignant cancers, intensive treatment 
in an emergency room or at home for allergic bronchospasm, blood dyscrasias or 
convulsions that do not result in hospitalization, or development of drug dependency 
or drug abuse.
Recording AE and SAE
AE and SAE Recording

When an AE/SAE occurs, it is the responsibility of the investigator to review all 
documentation (eg, hospital progress notes, laboratory, and diagnostics reports) 
related to the event.

The investigator will then record all relevant AE/SAE information in the eCRF.

It is not acceptable for the investigator to send photocopies of the participant’s 
medical records to GSK in lieu of completion of the GSK /AE/SAE eCRF page.

There may be instances when copies of medical records for certain cases are 
requested by GSK. In this case, all participant identifiers, with the exception of the 
participant number, will be redacted on the copies of the medical records before 
submission to GSK.

The investigator will attempt to establish a diagnosis of the event based on signs, 
symptoms, and/or other clinical information. Whenever possible, the diagnosis (not 
the individual signs/symptoms) will be documented as the AE/SAE.
Assessment of Intensity
The investigator will make an assessment of intensity for each AE and SAE reported 
during the study and assign it to 1 of the following categories: 

Mild: An event that is easily tolerated by the participant, causing minimal discomfort 
and not interfering with everyday activities.

Moderate: An event that causes sufficiently discomfort and interferes with normal 
everyday activities.

Severe: An event that prevents normal everyday activities. An AE that is assessed as 
severe should not be confused with an SAE. Severe is a category utilized for rating 
the intensity of an event; and both AE and SAE can be assessed as severe.
An event is defined as ‘serious’ when it meets at least 1 of the predefined outcomes 
as described in the definition of an SAE, NOT when it is rated as severe.


2016N291965_02
CONFIDENTIAL
204715
59
Assessment of Causality

The investigator is obligated to assess the relationship between study treatment and 
each occurrence of each AE/SAE.

A "reasonable possibility" of a relationship conveys that there are facts, evidence, 
and/or arguments to suggest a causal relationship, rather than a relationship cannot 
be ruled out.

The investigator will use clinical judgment to determine the relationship.

Alternative causes, such as underlying disease(s), concomitant therapy, and other 
risk factors, as well as the temporal relationship of the event to study treatment 
administration will be considered and investigated.

The investigator will also consult the IB and/or Product Information, for marketed 
products, in his/her assessment.

For each AE/SAE, the investigator must document in the medical notes that he/she 
has reviewed the AE/SAE and has provided an assessment of causality.

There may be situations in which an SAE has occurred and the investigator has 
minimal information to include in the initial report to GSK. However, it is very 
important that the investigator always make an assessment of causality for 
every event before the initial transmission of the SAE data to GSK.

The investigator may change his/her opinion of causality in light of follow-up 
information and send an SAE follow-up report with the updated causality 
assessment.

The causality assessment is one of the criteria used when determining regulatory 
reporting requirements.
Follow-up of AE and SAE

The investigator is obligated to perform or arrange for the conduct of supplemental 
measurements and/or evaluations as medically indicated or as requested by GSK to 
elucidate the nature and/or causality of the AE or SAE as fully as possible. This may 
include additional laboratory tests or investigations, histopathological examinations, 
or consultation with other health care professionals.

If a participant dies during participation in the study or during a recognized follow-
up period, the investigator will provide GSK with a copy of any post-mortem 
findings including histopathology.

New or updated information will be recorded in the originally completed eCRF.

The investigator will submit any updated SAE data to  GSK within 24 hours of 
receipt of the information.

CONFIDENTIAL
204715
60
Reporting of SAE to GSK
SAE Reporting to GSK via Electronic Data Collection Tool

The primary mechanism for reporting SAE to GSK will be the electronic data 
collection tool.

If the electronic system is unavailable for more than 24 hours, then the site will use 
the paper SAE data collection tool (see next section).

The site will enter the SAE data into the electronic system as soon as it becomes 
available.

The investigator or medically-qualified sub-investigator must show evidence within 
the eCRF (e.g., check review box, signature, etc.) of review and verification of the 
relationship of each SAE to study treatment (causality) within 72 hours of SAE entry 
into the eCRF. 

After the study is completed at a given site, the electronic data collection tool will be 
taken off-line to prevent the entry of new data or changes to existing data.

If a site receives a report of a new SAE from a study participant or receives updated 
data on a previously reported SAE after the electronic data collection tool has been 
taken off-line, then the site can report this information on a paper SAE form (see 
next section) or to the medical monitor by telephone.

Contacts for SAE reporting can be found in the SRM.
SAE Reporting to GSK via Paper CRF

Facsimile transmission of the SAE paper CRF is the preferred method to transmit 
this information to the medical monitor.

In rare circumstances and in the absence of facsimile equipment, notification by 
telephone is acceptable with a copy of the SAE data collection tool sent by overnight 
mail or courier service.

Initial notification via telephone does not replace the need for the investigator to 
complete and sign the SAE CRF pages within the designated reporting time frames.

Contacts for SAE reporting can be found in the SRM.

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


2016N291965_02
CONFIDENTIAL
204715
62
Men with a pregnant or breastfeeding partner must agree to remain abstinent from penile-
vaginal intercourse or use a male condom during each episode of penile penetration 
during the protocol-defined time frame.
Men must refrain from donating sperm for duration of study and for 90 days after study 
completion.
Female participants
Female participants of childbearing potential are not eligible to participate.

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

Pregnancy Testing

Women should only be included after a negative highly sensitive urine or serum 
pregnancy test 

Additional pregnancy testing will be performed before each PET scan, as required 
locally 
Collection of Pregnancy Information
Male participants with partners who become pregnant

Investigator will attempt to collect pregnancy information on any male participant’s 
female partner of a male study participant who becomes pregnant while participating 
in this study. This applies only to participants who receive study treatment.

After obtaining the necessary signed informed consent from the pregnant female 
partner directly, the investigator will record pregnancy information on the 
appropriate form and submit it to GSK within 24 hours of learning of the partner’s 
pregnancy. 

Partner will also be followed to determine the outcome of the pregnancy. 
Information on the status of the mother and child will be forwarded to GSK

Generally, follow-up will be no longer than 6 to 8 weeks following the estimated
delivery date. Any termination of the pregnancy will be reported regardless of fetal 
status (presence or absence of anomalies) or indication for procedure. 
Female Participants who become pregnant

Investigator will collect pregnancy information on any female participant, who 
becomes pregnant while participating in this study. 

Information will be recorded on the appropriate form and submitted to GSK within 
24 hours of learning of a participant's pregnancy. 

Participant will be followed to determine the outcome of the pregnancy. The 
investigator will collect follow up information on participant and neonate, which will 
be forwarded to GSK. Generally, follow-up will not be required for longer than 6 to 
8 weeks beyond the estimated delivery date.  

Any termination of pregnancy will be reported, regardless of fetal status (presence or 
absence of anomalies) or indication for procedure. 

While pregnancy itself is not considered to be an AE or SAE, any pregnancy 
complication or elective termination of a pregnancy will be reported as an AE or 
SAE. 

A spontaneous abortion is always considered to be an SAE and will be reported as 
such.  

Any SAE occurring as a result of a post-study pregnancy which is considered 
reasonably related to the study treatment by the investigator, will be reported to GSK
as described in Appendix 4. While the investigator is not obligated to actively seek 


2016N291965_02

Appendix 6: Genetics
USE/ANALYSIS OF DNA

Genetic variation may impact a participant’s response to therapy, susceptibility, 
severity and progression of disease. Variable response to therapy may be due to 
genetic determinants that impact drug absorption, distribution, metabolism, and 
excretion; mechanism of action of the drug; disease etiology; and/or molecular 
subtype of the disease being treated. Therefore, where local regulations and IRB/IEC 
allow, a blood sample will be collected for DNA analysis

DNA samples will be used for research related to GSK3008348 or IPF and related 
diseases. They may also be used to develop tests/assays including diagnostic tests) 
related to GSK3008348 (or study treatments of this drug class), and IPF. Genetic 
research may consist of the analysis of one or more candidate genes or the analysis 
of genetic markers throughout the genome [or analysis of the entire genome] (as 
appropriate)

DNA samples will be analyzed if it is hypothesized that this may help further 
understand the clinical data. 

The samples may be analyzed as part of a multi-study assessment of genetic factors 
involved in the response to GSK3008348 or study treatments of this class. The 
results of genetic analyses may be reported in the clinical study report or in a 
separate study summary.

The sponsor will store the DNA samples in a secure storage space with adequate 
measures to protect confidentiality. 

The samples will be retained while research on GSK3008348 (or study treatments of 
this class) or IPF continues but no longer than 15 years after the last visit of the last 
subject, or other period as per local requirements.

Appendix 8: Radiation Dose Risk Assessment
Participants will be exposed to an additional dose of ionising radiation as a consequence 
of their participation in this study. The ionising radiation exposure from PET and CT 
scanning comes from three sources. A proportion of the radiation exposure comes from 
the administered radioligand ([18F]-FBA-A20FMDV2). The remaining radiation dose 
comes from an HRCT for anatomical localisation (performed once only during the study) 
and low dose CT scans performed in order to correct the PET data for tissue attenuation. 
If the participant needs to be removed from the scanner and repositioned during the PET 
scan than a second low dose CT scan may be performed. The doses chosen for this study 
aim to deliver a minimal radiation exposure, compatible with a good quality PET and CT 
signal. 
Each participant will have up to three PET-CT scans. The effective dose for each 
radioligand administration will be 3.3 mSv based on a conversion factor of 
21.7 Sv/MBq determined from study RES116235 and a maximum administered activity 
of 150 MBq. A low-dose attenuation CT scan of the lung results in an effective dose of 
1.2 mSv. If the participant leaves the scanner during the scan and is repositioned, the CT 
scan will be repeated which would result in a further effective dose of 1.2 mSv. In 
addition, each participant will have one HRCT scan, resulting in an effective dose of 
3.8 mSv. The total effective dose to each participant will therefore be up to 3 x (3.3 + 2.4) 
+ 3.8 = 20.9 mSv. All of this exposure is over and above standard practice.
The total maximum effective dose of 20.9 mSv in this study is equivalent to 
approximately 9 times the average yearly exposure (2.3 mSv) from natural background 
radiation in the United Kingdom. The additional risk of developing a fatal malignancy as 
a result of these exposures has been estimated as approximately 1 in 1,000 for an adult in 
normal health. The reduced life expectancy of IPF patients will result in a lower risk for 
these individuals.
Within the UK the guidance set out by ICRP 62 is generally followed in setting research 
study dose constraints. The level of risk may therefore be assumed to broadly fall within 
the ICRP 62 intermediate Category IIb, where the benefit should be more directly aimed 
at the cure or prevention of disease.

Appendix 9: Assessment of the Potential Immunogenicity 
Risk for [18F]-FBA-A20FMDV2
Immunogenicity is a potential risk for exogenous peptides.  However, we consider the 
risk to be low under the current circumstances where the peptide is synthetic and is not 
administered repeatedly for clinical benefit, but is used as an imaging tracer. 
This potential risk may come from two sources: 
g.
pre-existing antibodies that may arise from prior exposure to the intact virus
h.
induction of a de novo immune response by exposure to the peptide
The risk assessment and management strategy is summarised in Table 3.

Previous exposure to 
FMDV may have 
elicited an immune 
response in certain 
individuals that may 
recognise the peptide
FMD is notifiable in 
the UK and the last 
outbreak was in 2007
FMD is endemic in 
certain areas of 
Africa, Asia and 
South America
Participants with prior exposure 
to farm animals are excluded 
from the study. 
Participants resident in 
endemic countries are 
excluded from the study.

Route of 
administration
[18F]-FBA-
A20FMDV2 will be 
administered 
intravenously. 
This route is less immunogenic 
than the subcutaneous route. 
Two participants in a previous 
study developed anti-peptide 
antibodies to this tracer but 
neither experienced any clinical 
event.
Low
Number and 
frequency of dosing
[18F]-FBA-
A20FMDV2 will be 
administered 2 or 3 
times to patients with 
IPF 
The 3 doses will be 
administered a maximum of 4  
weeks apart, reducing the 
potential for immune response 
maturation

Humans are likely to be

FBA-A20FMDV2 antibodies 
would require breaking

Risk level 
GSK2634673F is 
predicted to contain 
two sequences that 
have binding capacity 
for MHC class II
Aggregation of the peptide is 
minimal
Clinical relevance of in silico
predictions is uncertain, 
however a relevant T cell 
epitope cannot be excluded
In the absence of adjuvant a 
productive immune response is 
very unlikely
Risk mitigation measures
Clinical management
Although the risk of immunogenicity is low, some immune responses can progress to 
hypersensitivity reactions, such as IgE-mediated allergic reactions (anaphylaxis).  The 
impact of such a very rare event would be high. In order to manage this potential risk the 
following measures are in place at the site:

Crash trolleys are available on site

Suitably trained staff are available throughout the study

SOPs have been developed and are current at the site

Direct access to resuscitation teams and intensive care facilities are available 
immediately 
Assay to measure anti-peptide antibodies
Immunogenicity assessment will be performed for serum samples collected as per the 
SoA. Results will be analysed when the study is completed and will be correlated with 
any clinical or imaging observations.
Conclusions
Currently, the evidence suggests that the immunogenicity risk of [18F]-FBA-A20FMDV2, 
a synthetic 20 amino acid peptide, is predicted to be low. Mitigation strategies are 
incorporated into the protocol as described in the table above (such as exclusion of prior 
exposure to FMDV, short period between the 3 doses). In the unlikely event that 
anaphylaxis occurs, appropriate clinical management procedures are available 
immediately.

Section # 
and Name
Description of Change
Brief Rationale
7.4 Blinding
Clarified that the investigator may break the 
blind for a participant in an emergency, or if it 
is in the participant’s best interest for the 
investigator to know the study treatment 
assignment, whether or not an antidote is 
available, and that the responsibility lies with 
the investigator. The investigator is 
encouraged to discuss with GSK personnel 
before breaking the blind, but if not, may 
inform GSK after the event. 
As requested by the MHRA.

SUMMARY OF KEY PROTOCOL INFORMATION
2.1.
Changes to the Protocol Defined Statistical Analysis Plan
There are no changes or deviations to the originally planned statistical analysis specified 
in the protocol 2016N291965_02 (Dated: 24-JAN-2018). However, the protocol states 
that ‘If the study is stopped at the end of Cohort 1, then Cohort 2 will not proceed’, 
therefore, all analyses pertaining to Cohort 2 will not be conducted.

Study Design
Overview of Study Design and Key Features
Cohort 1 
Design
Features

This is a multi-centre, 2-cohort, study of single doses to investigate 
the safety, tolerability, PK and target engagement of nebulised 
GSK3008348, in patients with IPF.

Cohort 1 will be a randomised, double-blind (sponsor unblind), 
placebo-controlled group of 7 participants, randomised 5:2 to 
receive 1,000 µg GSK3008348 or placebo. After screening (within 
30 days of the first dose), all participants will have 2 dosing periods, 
and receive the same dose in each period as follows:  
o
Dosing period 1:  After pre-dose assessments at the clinical unit, 
participants will be admitted to the clinical unit the day of dosing 
(Day 1), stay overnight and be discharged after 24 h post-dose 
safety and PK assessments (Day 2).
o
Washout period: At least 7 days and no more than 28 days 
between doses.
o
Pre-dose scan: At least 7 days after the first dose, and no more 
than 14 days before the first post-dose PET.
o
Dosing period 2: Participants will have pre-dose assessments at 
the clinical unit. They will attend the imaging unit for dosing
and a 30 min post-dose PET scan and stay for at least 4 h post-
dose. Participants will return to the imaging unit on Day 2 for a 
24 h PET scan, and safety and PK assessments.

Cohort 2 was not conducted. It was optional and would have been
designed to further explore the safety of GSK3008348 and to 
provide additional information on the target engagement profile of 
GSK3008348. Based on Cohort 1 data, the decision was made to

Treatment 
Assignment

Cohort 1:

7 IPF patients will be enrolled. More IPF patients may be enrolled 
to achieve a target of 7 evaluable IPF patients.

Subjects in Cohort 1 will be randomised to receive either 1,000 µg 
GSK3008348 or placebo using a 5:2 ratio. 

Interim 
Analysis

An interim analysis to assess safety and tolerability, exposure and 
receptor engagement will occur at the end of Cohort 1. 

For safety assessments in Cohort 1, the review by the study team 
will include data on AEs, ECGs, pulmonary function, clinical 
laboratory values and VS.

Statistical Hypotheses / Statistical Analyses
All Parts:

The assessment of the safety and tolerability of single doses of nebulised 
GSK3008348 in this study will not include any formal statistical comparisons.
Cohort 1:

In Cohort 1, the primary comparison of interest is based on the changes in the uptake 
of [18F]-FBA-A20FMDV2 in the whole lung (assessed as the volume of distribution 
[VT], not corrected for air volume) at approximately 30 min post-dose compared to 
pre-dose, as measured by PET.

Interim Analyses
Details
Pharmacodynamics
(Cohort 1)

The purpose of the interim analysis at the end of Cohort 1 
was to provide the project team and key GSK stakeholders 
with data on receptor engagement to inform internal 
decision making. There were options to stop the study for 
success or to stop if it was deemed futile to proceed or to 
increase the sample size.

The interim occurred at the end of Cohort 1 when 5 IPF 
subjects receiving GSK3008348 had completed dosing 
period 2 and had a valid baseline and 30 minutes post-dose 
PET scan. 

The primary endpoint for decision-making at the interim 
analysis was the change in the uptake of [18F]-FBA-
A20FMDV2 in the whole lung (assessed as the volume of 
distribution [VT], not corrected for air volume) at 
approximately 30 min post-dose compared to pre-dose, as 
measured by PET

The review occurred on a clean database including the 
PET derived endpoints and the randomisation assignment. 
In addition, in-stream data reviews took place to ensure 
maximum data quality.

At the interim time point the change 30 minutes post-dose 
vs pre-dose in whole lung VT for the 5 active subjects was
analysed. The decision was made to stop the study due to 
success and evidence of receptor engagement, primarily
based on the predefined success criterion, i.e. the posterior 
probability that there was a reduction in uptake of [18F]-
FBA-A20FMDV2 in the whole lung (assessed as the 
volume of distribution [VT], not corrected for air volume) 
at approximately 30 min post-dose compared to pre-dose, 
as measured by PET.

Appropriate data summaries were at the treatment group 
level and individual subject numbers were scrambled so 
treatment allocation was not obvious.  The circulation of 
results was restricted to selected members of the GSK 
project team and key stakeholders. Interim results were
discussed with site investigators following internal review 
at GSK. 
PK

The purpose of the interim PK analysis at the end of 
Cohort 1 was to provide the study team with data on

(Cohort 1)
systemic exposure to inform dose selection for Cohort 2 
and/or dose selection for future studies and occurred at the 
end of Cohort 1.

PK analysis was performed on the data prior to cleaning. 
Additionally, the analysis was performed using nominal 
times and interim analysis was conducted on data with 
scrambled individual subject numbers. These scrambled 
numbers were different from scrambled numbers for the 
PET endpoint. The critical PK endpoints for assessment 
of systemic exposure were AUC and Cmax. AUC was
assessed as 0-t in the event of insufficient data to 
determine AUC(0-inf). Exposures relative to those observed 
at the NOAEL in toxicology studies were not calculated 
since we were not proceeding to Cohort 2.
Safety
(Cohort 1)

An informal review of safety data occurred at the end of 
Cohort 1. The purpose of this review was to compare 
safety parameters at the pre- and post-dose timepoints 
across both dosing periods and explore any safety signals 
that may have emerged.

The review by the study team included data on AEs,
ECGs, pulmonary function, clinical laboratory values and 
VS.

It was not expected that this review would occur on a 
clean database. No data listings were produced, and no 
statistical analysis was performed on the data.
3.2.
Final Analyses
The final planned primary analyses will be performed after the completion of the 
following sequential steps:
1.

PHARMACODYNAMIC ANALYSES
7.1.
Primary Pharmacodynamics Analyses
The three PET scans per subject will be denoted as ‘Pre-dose’ (Baseline PET in Period 
2), ‘PET1’ (Period 2, Day 1, 30 minutes PET after dose of GSK3008348, allowable time 
window is 20-60 mins) and ’PET2’ (Period 2, Day 2, 24 hours PET after dose of 
GSK3008348, allowable time window is 14-28 hrs).
7.1.1.
Endpoint / Variables
Change in the uptake of [18F]-FBA-A20FMDV2 in the whole lung (assessed as the 
volume of distribution [VT], not corrected for air volume) at approximately 30 min post-
dose compared to pre-dose, as measured by PET. VT is implicitly corrected for blood
volume.
7.1.2.
Summary Measure
Ratio (PET1/Pre-dose) in the volume of distribution (VT), not corrected for air volume at 
approximately 30 min post-dose as measured by PET.
7.1.3.
Population of Interest 
The primary pharmacodynamic analyses will be based on the Per-Protocol (PP)
population, unless otherwise specified.
7.1.4.
Strategy for Intercurrent (Post-Randomisation) Events
Several post-randomisations events have been considered e.g. use of rescue medication, 
discontinuation of treatment, treatment switching and death. Due to the short duration of 
the study (and the time at which the pharmacodynamic endpoint is measured; baseline, 
30mins and 14-28hrs post-dose) these post-randomisation events have been deemed to 
have little impact on the endpoint.
Therefore, a treatment policy approach will be adopted hence the actual values of the 
endpoint regardless of whether the intercurrent event has occurred will be analysed.
7.1.5.
Statistical Analyses / Methods
Details of the planned displays are provided in Appendix 12: List of Data Displays and 
will be based on GSK data standards and statistical principles.
Unless otherwise specified, endpoints/variables defined in Section 7.1.1 will be 
summarised using descriptive statistics, graphically presented (where appropriate) and
listed.

7.1.5.1.
Statistical Methodology Specification
Endpoint / Variables

VT (whole lung, not corrected for air volume), at 1000 mcg GSK3008348
Timepoint

The primary timepoint of interest is the 30 minutes post-dose PET scan timepoint.
Model Specification

The distribution of VT will be explored using graphical approaches. It is likely that 
this follows a log-normal distribution in which case the logarithm transformation 
will be applied, and a normal distribution assumed for log (VT).

Only data from those subjects receiving 1,000 mcg GSK3008348 will be included 
in the primary analysis (i.e., no placebo data will be included) in Cohort 1.

The three PET scans per subject will be denoted by Pre-dose (Baseline PET in 
Period 2), PET1 (Period 2, Day 1, 30 minutes PET after dose of GSK3008348, 
allowable time window is 20-60 mins) and PET2 (Period 2, Day 2, 24 hours PET
after dose of GSK3008348, allowable time window is 14-28 hrs).

The mean of the normal distribution will be allowed to vary per post-dose scan 
timepoint by defining the 3-dimensional array parameter ResponsebyVisit as 
follows:
o
ResponsebyVisit[1]  = mean of log (Response) at ‘Pre-dose’
o
ResponsebyVisit[2]  = mean of log (Response) at ‘PET1’
o
ResponsebyVisit[3]  = mean of log (Response) at ‘PET2’

In addition, the following 3 - dimensional array parameter ResponseRatio will also 
be created:
o
ResponseRatio[1] = PET1/Pre-dose
o
ResponseRatio[2] = PET2/Pre-dose
o
ResponseRatio[3] = PET2/PET1

The inclusion of covariates Age, Sex, Baseline % predicted FVC, and Baseline % 
predicted DLCO (baseline from Period 2) will be explored in a sequential manner 
and included in the model if the 95% HPD credible interval for the corresponding 
regression coefficient excludes 0.

This endpoint will be analysed using Bayesian inference assuming non-informative 
priors of the form N(mean=0, SD = 1000) for all regression coefficients in the 
model.

An unstructured 3x3 variance-covariance matrix will be assumed to model the 
dependency between log (VT) in the three PET scans. If the model fails to converge 
then additional structures such as the Toeplitz structure should be explored. Details 
of the prior distributions are presented in Section 12.2.
Model Checking & Diagnostics


The adjusted posterior median values of VTRatio (PET1/Pre-dose, PET2/Pre-dose
and PET2/PET1) will be presented in tabular form together with the corresponding 
standard deviations and 95% HPD credible intervals.

Plots of individual subject data for PET1/Pre-dose, PET2/ Pre-dose and 
PET2/PET1 will be superimposed with the adjusted posterior median values of 
PET1/Pre-dose, PET2/Pre-dose and PET2/PET1 respectively. These plots should 
also include the corresponding 95% HPD credible intervals for PET1/Pre-dose, 
PET2/Pre-dose and PET2/PET1. 

The posterior probability that the true ratio PET1/Pre-dose is less than 1 will be 
calculated.
Subgroup Analyses

None
Sensitivity and Supportive Analyses

Following review of the data, additional analyses may be conducted to further 
support the primary statistical analysis, if deemed appropriate. The posterior 
probability that the true ratio PET1/Pre-dose is less than 0.9, 0.8, 0.7 and 0.6, as 
appropriate depending on the observed data, will also be calculated. If the PP and 
ITT populations differ, the same statistical analysis using the ITT population will 
also be conducted.

Secondary Pharmacodynamic Analyses
The secondary pharmacodynamic analyses will be conducted in the same manner as the 
primary pharmacodynamic analyses. The only difference is that the timepoint of interest 
is now PET2. The output corresponding to the secondary pharmacodynamic analysis will 
be obtained from the primary pharmacodynamic analysis and corresponds to PET2/Pre-
dose and PET2/PET1.

Pharmacodynamic Interim Analyses
The interim analysis for pharmacodynamics in Cohort 1 was based on the Per Protocol 
population.
The interim analysis was conducted in the same manner as the primary pharmacodynamic 
analysis and the primary timepoint of interest was the 30 minutes post-dose scan 
timepoint. The secondary timepoint of interest was the 14-28hrs post dose scan point.
The data was reported to the study team with scrambled individual subject numbers.

12.2.1.
General Considerations for Bayesian Analysis

The following points are for guidance and illustration only and do not guarantee a 
successful model convergence. They cannot cover all eventualities and do not remove 
the requirement to do what is best for the specific set of observed data being 
modelled.

Unless otherwise stated, data collected at screening and at unscheduled time points 
will not be included in the statistical analyses, i.e., only planned/scheduled post-
screening data will be included except where screening data is used as baseline. 

All credible intervals reported will be 95% HPD intervals, unless otherwise specified.

After Markov Chain Monte Carlo (MCMC) for Bayesian inference, estimated and 
monitored model parameters (variance components and fixed effects) were compared 
to corresponding estimated parameters from the linear mixed model. Confidence was 
gained if results were similar. Different initial values for fixed effects (but not 


CONFIDENTIAL
204715
36
variance components) were used to assess convergence. Convergence for all the 
parameters in the model needs to be verified

A separate seed for each MCMC chain will be set to ensure reproducibility.
12.2.1.1.
Prior Distributions
Unless otherwise specified, the following will be the default approach to selecting prior 
distributions:

Non-informative priors of the form Normal (0, Var=1E6) will be assigned to each 
fixed-effect parameter in the proposed statistical model.

For repeated measures models, non-informative Inverse-Wishart priors of the 
form IW (υ, Σ) will be assigned for the Variance-Covariance (VC) matrix 
associated with the repeated measures timepoints. The parameter υ represents the 
dimension of VC (number of rows or columns) and the matrix Σ is an identity 
matrix of the same dimension as VC. The unstructured variance covariance 
structure for the repeated measurements will be assumed. In cases of non-
convergence, the Toeplitz structure will be used.
o
If there are issues with these distribution parameters, then Σ may be a 
diagonal matrix that uses best guesses for the residual variance at each 
repeated measure timepoint (or the residual estimate from fitting simple 
models). This only needs to be of the correct order of magnitude.

Non-informative inverse-gamma priors of the form IG(a=2.001, b=0.001) will be 
used for scale parameters (variances). If these parameters do not lead to 
convergence, then choose “a” small and “b” smaller than the expected standard 
deviation.   
It is good practice to ensure that each prior distribution is visualized to ensure it appears 
sensible, i.e., that it allows parameter values that generate clinically plausible response 
values and that it is truly non-informative over the region of the likelihood function 
where the data lies.
Note: 

The Gamma(a,b) density function takes the form
The mean is a/b and the variance is a/b2.

The IG(a,b) density function takes the form


CONFIDENTIAL
204715
37
The mode is b/(a+1), the mean is b/(a-1), if a>1, and the variance is b2/[(a-1)2(a-
2)], if a>2.

There is no requirement to formally report the prior visualisation outputs.
12.2.1.2.
Initial Values
The two MCMC chains should be generated using over-dispersed initial values. To 
achieve this the sample standard deviation of the change from baseline in log(response), 
SD_hat, should be estimated. The two over-dispersed initial values for the parameters 
(ResponsebyVisit) should then be sampled from the following normal distribution N(0, 
SD = 10*SD_hat).
For the remaining model parameters over-dispersed initial values may be drawn at 
random from their respected prior distribution.  If convergence of the Markov chain 
Monte Carlo (MCMC) algorithm is problematic then alternative estimates may be used 
(for example, these could be based on maximum likelihood estimates).
12.2.1.3.
Convergence Diagnostics
To be able to perform Bayesian inference using MCMC simulations the posterior samples 
for all the parameters in the model need to be obtained from the corresponding target 
posterior distribution. To ensure that this is the case the following is a list of convergence 
diagnostics that can be applied for each parameter:
Comparing MCSE vs. posterior standard deviation:

The Monte Carlo Standard Errors (MCSE) should be compared with the standard 
deviation of the posterior distribution (SD) to ensure that only a fraction of the 
posterior variability is due to the simulation, i.e., the ratio MCSE/SD should be as 
small as possible, typically < 0.01.  

Adequate values for the number of MCMC samples / thinning / number of burn-in 
samples should be chosen to ensure that the ratio MCSE/SD for all the parameters 
in the model is < 0.01. 

In addition, if possible, the number of tuning units and maximum number of 
tuning iterations may be increased to find a better proposal distribution for the 
model parameters, which in turn may reduce the MCSE/SD ratio.

Where possible the code should be written to allow the SAS compiler to identify 
and make use of conjugacy, since this can greatly reduce the corresponding 
MCSE/SD ratio.

Models selected with MCSE/SD values > 0.01 would need a brief 
remark/justification added to the CSR to clarify why it was not possible to reach 
the target and why it is believed the subsequent model still has utility from an 
inference perspective.


CONFIDENTIAL
204715
38
Gelman & Rubin diagnostics:

The Gelman & Rubin diagnostic assessment will be used to assess convergence of 
the multiple chains.

The Gelman & Rubin diagnostic is based on running multiple Markov chains, say 
m, each with n draws, with the different chains started at initial values that should 
be overdispersed relative to the target posterior distribution. Thus, the m chains 
yield m possible inferences; to answer the question of whether these inferences 
are similar enough to indicate approximate convergence, Gelman, 1992 suggested
comparing these to the inference made by mixing together the m*n draws from all 
the sequences as follows: the pooled variance across the chains is compared to the 
overall within-chain variance using a ratio, usually called the potential scale 
reduction factor, or
.

Values of 
close to 1 indicate that each of the m sets of n simulated observations 
is close to the target posterior distribution.

Although PROC MCMC in SAS does not provide the Gelman & Rubin , SAS 
has provided a macro, %gelman, for determining the statistic (note that for this to 
work at least two MCMC chains need to be generated, which means that PROC 
MCMC needs to be call as many times as the number of chains, with the different 
starting values). 
Diagnostic plots and visual inspection:

Trace plots of samples versus the simulation index can be used to assess some 
aspects of convergence. The centre of the chain should appear stable with very 
small fluctuations, i.e., the distribution of points should not change as the chain 
progresses and the posterior mean and variance are relatively constant.

Autocorrelation plots provide information on how slow or fast the Markov chain 
converges. If the autocorrelation does not decrease rapidly this means that the 
chain needs to be run for longer to achieve convergence.

Examination of correlation structures between relevant posterior parameters 
should be used to provide information about what potential issues may be and 
also what corrective action(s) may be worthwhile attempting.
Convergence for all the parameters in the model needs to be verified (apart from subject-
specific random effects).
12.2.2.
General Considerations for All Analyses
Model assumptions will be applied, but appropriate adjustments may be made based on 
the data. If there are any departures from the distributional assumptions, alternative 
models will be explored using appropriate transformed data.


CONFIDENTIAL
204715
39
Distributional assumptions underlying the model used for analysis will be examined 
through graphical approaches by assessing the distribution of the residuals against the 
assumed distribution of the response, and by assessing the distribution of the residuals 
against the fitted response values.
Outputs of the residual plots as a check of the normality assumptions of the log(response) 
will be produced.

Appendix 6: Derived and Transformed Data
15.6.1.
General
Multiple Measurements at One Analysis Time Point

Mean of the measurements will be calculated and used in any derivation of summary 
statistics but if listed, all data will be presented.

If there are two values within a time window (as per Section 15.3.1) the value closest 
to the target day for that window will be used. If values are the same distance from 
the target, then the mean will be taken.

Participants having both High and Low values for Normal Ranges at any post-
baseline visit for safety parameters will be counted in both the High and Low 
categories of “Any visit post-baseline” row of related summary tables. This will also 
be applicable to relevant Potential Clinical Importance summary tables.
Study Day

Calculated as the number of days from First Dose Date within a treatment period:
o
Ref Date = Missing              → Study Day = Missing 
o
Ref Date < First Dose Date → Study Day = Ref Date – First Dose Date
o
Ref Data ≥ First Dose Date → Study Day = Ref Date – (First Dose Date) + 1

ECG Parameters
RR Interval

ECGs are machine read, the RR value preceding the measurement QT interval was 
only collected during Imanova visits. Missing RR interval (msec) will not be derived.
Corrected QT Intervals

When not entered directly in the eCRF, corrected QT intervals by Bazett’s (QTcB) 
and Fridericia’s (QTcF) formulas will be calculated, in msec, depending on the 
availability of other measurements.

If RR interval (msec) is provided then missing QTcB and/or QTcF will be derived as:

Laboratory Parameters

If a laboratory value which is expected to have a numeric value for summary 
purposes, has a non-detectable level reported in the database, where the numeric 
value is missing or replaced with a character value starting with '<x' or '>x' (or 
indicated as less than x or greater than x in the comment field), the number of 
significant digits in the observed values will be used to determine how much to add or 
subtract in order to impute the corresponding numeric value. 
o
Example 1: 2 Significant Digits = ‘< x ' becomes x - 0.01
o
Example 2: 1 Significant Digit   = ‘> x' becomes x + 0.1
o
Example 3: 0 Significant Digits = '< x' becomes x - 1.    

If there is more than one value of a particular parameter for a subject for a visit, the 
scheduled value will be used in summary statistics; all values will be listed.

Appendix 7: Reporting Standards for Missing Data
15.7.1.
Premature Withdrawals
Element
Reporting Detail
General

Subject study completion is defined as a subject having reached Last 
Subject Last Visit (LSLV) at the end of Dosing Period 2 in Cohort 1.

Withdrawn subjects will be replaced in the study if they withdraw 
before successful completion of the 30mins PET scan in Dosing 
Period 2 of Cohort 1.

All available data from participants who were withdrawn from the 
study will be listed and all available planned data will be included in 
summary tables and figures, unless otherwise specified.

Withdrawal visits will be slotted as per Appendix 3: Assessment 
Windows or will be summarised as withdrawal visits.
15.7.2.
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:
o
These data will be indicated using 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. 
o
Answers such as “Not applicable” and “Not evaluable” are not 
considered to be missing data and should be displayed as such.
Outliers

Any participants excluded from the summaries and/or statistical 
analyses will be documented along with the reason for exclusion in the 
clinical study report.
PK

Adjustments to the derivation of PK parameters where NQ values are 
present in the data will be performed according to how extensive the NQ 
values are and which treatment groups the NQ’s are present in. Refer to 
the Standards for the Handling of NQ impacted PK Parameters 
documentation.
PET

Missing PET measurements will not be imputed.
15.7.2.1.
Handling of Missing and 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:
o
Missing Start Day: First of the month will be used unless this 


CONFIDENTIAL
204715
55
Element
Reporting Detail
is before the start date of study treatment; in this case the 
study treatment start date will be used and hence the event is 
considered On-treatment as per Appendix 4: Study Phases and 
Treatment Emergent Adverse Events.
o
Missing Stop Day: Last day of the month will be used, unless 
this is after the stop date of study treatment; in this case the 
study treatment stop date will be used.

Completely missing start or end dates will remain missing, with no 
imputation applied. Consequently, time to onset and duration of such 
events will be missing.
Concomitant 
Medications/
Medical 
History

Partial dates for any concomitant medications recorded in the CRF 
will be imputed using the following convention:
o
If the partial date is a start date, a '01' will be used for the day 
and 'Jan' will be used for the month
o
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.
15.7.2.2.
Handling of Missing Data for Statistical Analysis
For statistical analysis purposes, data will be assumed to be Missing at Random (MAR)
and no imputation will be conducted.
