Conditions: Asthma
Keywords: Fluticasone furoate/vilanterol Asthma fraction of exhaled nitric oxide cross-over
Allocation: RANDOMIZED | Intervention model: CROSSOVER
Enrollment: 28
Healthy volunteers: no

Brief summary:
For asthmatic subjects, a combination of inhaled corticosteroid (FF) and long-acting beta2 receptor agonist (VI) is recommended for use (once daily) and fraction of exhaled nitric oxide (FeNO) is a non-invasive airway inflammation marker.

In this randomised, double blind, placebo-controlled, two-period, crossover repeat dose study, the duration of action of fluticasone furoate (FF) will be determined by monitoring the return of FeNO levels to baseline, following the treatment with FF/vilanetrol (VI) in asthmatic subjects.

Subjects who meet the eligibility criteria will participate in the following two treatment periods: FF/VI 100/25 mcg once-daily and placebo once-daily. Approximately 28 subjects will be enrolled in order to achieve 24 evaluable subjects. A 2-week treatment period will be followed by a 21-day monitoring/washout period before crossing over to the next treatment period. Total duration of each subject will be a maximum of 21 weeks. FeNO will be monitored up to 21 days after treatment with FF/VI together with FEV1 (up to 7 days).

Detailed description:

Arms:
arm 1: Subjects will receive FF/VI 100/25 mcg each morning (once daily) from Day 1 to Day 14, followed by a 21-day monitoring/washout period arm 2: Subjects will receive placebo each morning (once daily) from Day 1 to Day 14, followed by a 21-day monitoring/washout period

Interventions: intervention 1: Fluticasone furoate (FF) (100 mcg) intervention 2: Vilanterol (VI) (25 mcg) intervention 3: Placebo
Intervention descriptions: intervention 1: First blister strip contains FF blended with lactose, 100 mcg per blister intervention 2: Second blister strip contains vilanterol blended with lactose and magnesium stearate, 25 mcg per blister intervention 3: Matching placebo will have two blister strips, identical in appearance to the inhaler containing active study medication; one containing lactose and the second strip containing lactose and magnesium stearate

Overall Design
This study will be a randomised, double blind, placebo-controlled, two-period, crossover 
repeat dose study in adult subjects with asthma.
Following screening, subjects will provide AM and PM FeNO and PEF data from Day -7 
of Treatment Period 1.  The Day -7 AM FeNO readings will be used to confirm eligibility 
(FeNO >40ppb).  On Day 1, pre-treatment (AM) FeNO, FEV1 and PEF readings will be
used as baseline for Treatment Period 1.  Subjects will then receive FF/VI 100/25 or 
placebo once daily (AM) for 14 (2) days. All treatments will be taken at the same time 
of day (within 2 hours of the treatment on Day 1).
FeNO will be measured by the subjects AM (pre-dose) and PM for 14 days during each 
treatment period. On Day 14, FEV1 and FeNO will be recorded before the final dose of 
FF/VI or placebo.
FeNO (AM and PM) will be measured for 21 days after the end of treatment (up to Day 
35 for each of the two treatment periods). This will be as an in-patient on Days 14 to 19.  
All FeNO (out-patient and in clinic) measurements will be obtained using the same FeNO 
meter for each subject.
FEV1 will be recorded AM and PM (i.e. every 12 hours) as an in-patient on Days 14 to 
19. Subjects will then be discharged before returning 2 days later (on Day 21) for a 
further measurement of FEV1 (168 hours post-treatment). An FEV1 measurement will 
also be performed on Day 35.
Up to 4 weeks after the final assessment is collected on Day 35 of Treatment Period 1, 
subjects will then be crossed over to the alternative treatment.  Baseline FEV1, PEF and 
FeNO values will be collected pre-treatment in the morning on Day 1: these will be the 
baseline values for Treatment Period 2.  Subjects will then receive FF/VI 100/25 or 
placebo once daily (AM) for 14 (2) days. The second treatment period procedures will 
be identical to the first treatment period.
A single measurement of FeNO will be collected according to American Thoracic 
Society (ATS)/European Respiratory Society (ERS) guidelines at each time point, using a 
NIOX Vero device with electronic data capture. Appropriate dietary and/or lifestyle 
restrictions will be applied.  The order of assessments collected in the clinic will be: 
FeNO, FEV1, and then PEF. When the subjects are at home, FeNO will be collected 
before the PEF measurements. FEV1 measurements taken within 6 hours of short acting 
beta2-receptor agonist (SABA) use will not be analysed.
PEF measurements (best of 3 recordings) will be recorded AM and PM (i.e. every 12 
hours) from Day-7 through to Day 35 of Treatment Period 1, and then from Day 1 of 
Treatment Period 2 through to the follow-up visit. Subjects will be provided with a PEF 
meter and these measurements will be captured electronically whilst they are at home and 
in the clinic.

Treatment Arms and Duration
Each subject will participate in two treatment periods of 14 (2 days).  FF/VI 100/25 
mcg will be received once daily (AM dosing) in one period and placebo (AM dosing) 
will be administered in the other period.  At the end of each treatment period, there will 
be a monitoring period of 21 days.
Total duration for each subject (from screening to follow-up) will be a minimum of 76 
days, with a maximum of up to 21 weeks, depending on the screening period and the time 
period between Treatment Periods 1 and 2.
A complete subject is one who has completed both treatment periods, all assessments up 
to Day 35 of both treatment periods, and all of the follow-up assessments.
Type and Number of Subjects
Approximately 28 adult subjects with asthma will be enrolled into this study to ensure 
that 24 subjects complete dosing and critical assessments for both treatment periods.
Analysis
Following loge-transformation, primary endpoint of FeNO change from baseline ratio
following cessation of treatment will be analyzed using a mixed effects repeated 
measures model with fixed effect terms for period, treatment, day, time, (period-level 
baseline)*day*time interaction term, treatment*day*time interaction term, period-level 
baseline and subject-level baseline. Day*time interaction term will be fitted as repeated 
measure.
Secondary endpoints of FeNO change from baseline ratio during treatment and FEV1 will 
be analysed similarly to the primary FeNO endpoint.  FEV1 will not be log-transformed.
PEF and safety data will be listed and summarised. Exploratory biomarker data 
(including blood eosinophil and serum periostin data) will be summarized descriptively, 
if available.

INTRODUCTION
2.1.
Study Rationale/Brief Background
Treatment with an inhaled corticosteroid (ICS) is recommended for asthma patients who 
are symptomatic while taking as-needed short acting bronchodilators. In patients who 
remain symptomatic on low to medium doses of ICS, treatment with a combination of a 
long-acting β2 agonists (LABA) and an ICS is recommended. The combination of the 
ICS fluticasone furoate (FF) and the LABA vilanterol (VI) is approved for the once daily 
treatment of asthma (RELVAR ELLIPTA or BREO ELLIPTA; 100/25 and 200/25 mcg).
The FF/VI asthma clinical development program demonstrated efficacy over the 24 hour 
dosing interval resulting in regulatory approvals for once-daily administration. The 
duration of bronchodilation produced by a single dose of FF/VI 100/25 mcg beyond the 


2015N241692_00
CONFIDENTIAL
201499
11
24 hour dosing interval was assessed [GlaxoSmithKline Document Number 
2014N194756_00] and showed clinically significant bronchodilation over 48 hours with 
effects still apparent up to 72 hours post-dose. This effect was predominantly attributed 
to the LABA (VI) component. The persistence of the anti-inflammatory effect of the ICS 
(FF) component of FF/VI following cessation of dosing has not been determined.
In subjects with asthma the fraction of exhaled nitric oxide (FeNO) is a non-invasive 
marker of airway inflammation. In symptomatic subjects high FeNO levels (>50ppb) 
indicate significant airway eosinophilia which is likely to respond to ICS (Taylor, 2006; 
Smith, 2005).  The onset of action for ICS in reducing FeNO occurs within one week and 
is maintained with chronic dosing (Kharitonov, 2002; Nolte, 2013). Dose-related 
reductions in FeNO have been shown with low dose ICS (Kharitonov, 2002; Silkoff, 
2001), while fluticasone propionate (FP) produced comparable near-maximal reductions 
in FeNO across a wide dose range (50-2,000 mcg/5 days) with a maximum possible 
effect for the agonist (Emax) of 63% reduction and an effective dose for 50% of people 
receiving the drug (ED50) of 18 mcg which is below the minimal approved clinical dose 
[GSK Document Number GM2005/00525/00]. A limited investigation (3 days 
treatment) of the effects of high doses of FF (250 mcg and 1000 mcg) in comparison with 
FP (1000 mcg) on FeNO was conducted during the early clinical development of FF 
[GSK Document Number GM2003/00418/00]. Both FF and FP reduced FeNO with a 
greater effect seen with FF 1000 mcg compared with either FF 250 mcg or FP 1000mcg.  
However, the overall response to FP was approximately half that produced by the same 
dose administered for 5 days [GSK Document Number GM2005/00525/00] indicating 
that the 3 day treatment duration may have been insufficient to produce maximal
reductions in FeNO. In a study with mometasone furoate (Nolte, 2013) a greater effect 
on FeNO was seen after 14 days compared with the response at 7 days across all doses 
(100, 200 and 400 mcg), although the difference was minimal (approximately 90% of the 
Day 14 response was apparent by Day 7).  This indicates a treatment with ICS for at least 
14 days is necessary for the optimal effect on airway inflammation as measured by 
FeNO.
Following the cessation of ICS treatment FeNO levels progressively return to pre-
treatment baseline levels, suggesting a return of inflammation.  FeNO levels returned to 
baseline 7 days after cessation of treatment with budesonide (Kharitonov, 2002) and two 
weeks after administration of FP 1000 mcg/day for one month, although earlier time-
points were not assessed (Van Rensen, 1999).  Following short term FF treatment (3 
days) FeNO levels remained lowered for 72 hours after the last dose [GSK Document 
Number GM2003/00418/00]; later time-points were not investigated.  
FF demonstrates a number of characteristics that could result in a prolonged anti-
inflammatory action including a greater glucocorticoid receptor binding and higher tissue 
uptake and retention than other ICS molecules (Salter, 2007; Valotis, 2007) together with 
a longer lung retention than FP in man (Allen, 2013).  The duration of anti-inflammatory 
activity of the FF component of FF/VI beyond the 24 hour dosing interval is not known.
This study will determine the duration of action of FF by monitoring the return of FeNO 
levels to baseline following the cessation of repeat dose treatment with FF/VI. The study 
will use a clinical strength of FF/VI (RELVAR ELLIPTA 100/25 mcg Once Daily (OD)) 
administered for a two week treatment period. FeNO will continue to be monitored up to

12
21 days after treatment with FF/VI together with forced expiratory volume in 1 second 
(FEV1) (up to 7 days).
Information on the physical, chemical and pharmaceutical properties of FF/VI is 
available in the Investigator Brochure (IB) [GlaxoSmithKline Document Number 
RM2008/00012/07] and also in the BREO ELLIPTA datasheet on the New Zealand

STUDY DESIGN
4.1.
Overall Design
This study will be a randomised, double blind, placebo-controlled, two-period, crossover 
repeat dose study in adult subjects with asthma.
Following screening, subjects will provide AM and PM FeNO and PEF data from Day -7 
of Treatment Period 1.  The Day -7 AM FeNO readings will be used to confirm eligibility 
(FeNO >40ppb).  On Day 1, pre-treatment (AM) FeNO, FEV1 and PEF readings will be 
used as baseline for Treatment Period 1.  Subjects will then receive FF/VI 100/25 or 
placebo once daily (AM) for 14 (2) days. All treatments will be taken at the same time 
of day (within ± 2 hours of the treatment on Day 1).
FeNO will be measured by the subjects AM (pre-dose) and PM for 14 days during each 
treatment period. On Day 14, FEV1 and FeNO will be recorded before the final dose of 
FF/VI or placebo.
FeNO (AM and PM) will be measured for 21 days after the end of treatment (up to Day 
35 for each of the two treatment periods). This will be as an in-patient on Days 14 to 19.  
All FeNO (out-patient and in clinic) measurements will be obtained using the same FeNO 
meter for each subject.
FEV1 will be recorded AM and PM (i.e. every 12 hours) as an in-patient on Days 14 to 
19. Subjects will then be discharged before returning 2 days later (on Day 21) for a 
further measurement of FEV1 (168 hours post-treatment). An FEV1 measurement will 
also be performed on Day 35.
Up to 4 weeks after the final assessment is collected on Day 35 of Treatment Period 1, 
subjects will then be crossed over to the alternative treatment.  Baseline FEV1, PEF and 
FeNO values will be collected pre-treatment in the morning on Day 1: these will be the 
baseline values for Treatment Period 2.  Subjects will then receive FF/VI 100/25 or 
placebo once daily (AM) for 14 (2) days. The second treatment period procedures will 
be identical to the first treatment period.
A single measurement of FeNO will be collected according to ATS/ERS guidelines at 
each time point, using a NIOX Vero device with electronic data capture. Appropriate 
dietary and/or lifestyle restrictions will be applied.  The order of assessments collected in 
the clinic will be: FeNO, FEV1, and then PEF. When the subjects are at home, FeNO will 
be collected before the PEF measurements. FEV1 measurements taken within 6 hours of 
SABA use will not be analysed.
PEF measurements (best of 3 recordings) will be recorded AM and PM (i.e. every 12 
hours) from Day-7 through to Day 35 of Treatment Period 1, and then from Day 1 of 
Treatment Period 2 through to the follow-up visit. Subjects will be provided with a PEF 
meter and these measurements will be captured electronically whilst they are at home and 
in the clinic.

Design Justification
Treatment period. The characterisation of the FeNO time profile following 
administration of FF is not known and its determination is the primary objective of this 
study. The onset of action of ICS on FeNO occurs within a few days with significant and 
near maximal effects seen after one week. In subjects with asthma and elevated FeNO 
(mean baseline eNO >65ppb) treatment with FP for 5 days reduced FeNO by 47-60% 
with a similar effect produced across a 40-fold dose range (50-2,000 mcg twice daily 
(BD); GSK Document Number GM2005/00525/00). A lesser reduction of approximately 
33% from baseline was seen with FP 1,000 mcg BD for 3 days [GSK Document Number 
GM2003/00418/00] suggesting that this treatment duration may have been sub-optimal.  
Approximately 90% of the maximal effect of mometasone furoate on FeNO was seen 
after 7 days treatment compared with 14 days treatment (Nolte, 2013) These data suggest 
that the selected treatment period of 14 days should be associated with a near maximal 
effect of FF on eNO and that a longer treatment duration would be unlikely to result in 
further substantial effects.
Washout. As the duration of action of FF on eNO is not known, the washout period of at 
least 21 days represents a pragmatic balance between a likely duration of action and 
successful and timely study completion. A washout period of 14-28 days was 
successfully used in a previous study with repeat dose FP [GSK Document Number 
GM2005/00525/00]. There is a minimum of a 21 day washout period from the end of 
Treatment Period 1 to the start of Treatment Period 2. This is expected to be a sufficient 
washout for FeNO levels to return to baseline. However, to provide flexible scheduling 
for Treatment Period 2, there may be a further period of up to 4 weeks after the end of 
this initial 21 day washout period has finished before the subject commences Treatment 
Period 2.
Design Rationale. A placebo-controlled double-blind crossover study is preferred to a 
parallel group as this will require fewer subjects.  Screening failure rates in a similar 
study [GSK Document Number 2014N194756_00] at the same site were in the order of 
90% and a parallel group study is not considered to be feasible.  The drop-out rate 
predicted for this study is considered to be low (based on the previous study HZA116592 
conducted at the same site) [GSK Document Number 2014N194756_00].
Baseline FeNO (for eligibility). Based on the ATS FeNO 2011 guidelines [ATS, 2011],
the lower limit of 40ppb to be used in this study is classified as ‘intermediate’ (range 25-
50ppb). Patients with intermediate FeNO values respond to ICS treatment and clinical 
cut-offs between 35 and 50ppb have been linked with a high likelihood of asthma 
diagnosis as well as an increased risk of worsening symptoms and exacerbations 
(Bjermer, 2014).  FeNO >40ppb is considered to be elevated and this lower limit has 
previously been successfully used by the study site. In a previous study with repeat dose 
FP in AMP sensitive asthmatics receiving SABA only [GSK Document Number 
GM2005/00525/00], mean baseline FeNO across the treatments ranged between 66 and 
85ppb.
Dietary and smoking restrictions. In healthy subjects, eNO increased by 60% two hours 
after a nitrate-rich meal and was still 22% higher than baseline after 15 hours before 


2015N241692_00
CONFIDENTIAL
201499
16
returning to baseline at 20 hours [Vints, 2005]. Therefore, avoidance of nitrate-rich foods 
is a restriction in this study.
Smoking can reduce FeNO by 30-60%, dependent on daily cigarette consumption
(Bjermer, 2014).  Consequently, all subjects will be non-smokers.
4.5.
Dose Justification
FF/VI 100/25 mcg represents the lower approved dose for asthma (RELVAR ELLIPTA 
and BREO ELLIPTA) and is likely to be the most frequently prescribed strength. The 
predicted effects of FF/VI 200/25 on FeNO would either be of comparable or of longer 
duration and therefore the 100/25 mcg dose represent the ‘worst case’ in terms of 
duration. The dose response for FF reduction in eNO is not known. However, repeat 
dose FP for 5 days [GSK Document Number GM2005/00525/00] produced similar 
reductions in FeNO (ranging from 47% [50 mcg BD] to 60% [2,000 mcg BD] with an 
ED50 of 18 mcg and an Emax of 63%). Given the greater potency, higher glucocorticoid 
receptor selectivity, greater tissue uptake and longer intracellular and lung retention of FF 
compared with FP it is considered to be reasonable to assume that FF 100 mcg for 14 
days will produce a maximal or near maximal reduction of eNO.
4.6.
Benefit:Risk Assessment
Summaries of findings from both clinical and non-clinical studies conducted with FF/VI
can be found in the Investigator’s Brochure) [GlaxoSmithKline Document Number 
RM2008/00012/07] and also in the BREO ELLIPTA datasheet on the New Zealand 
Medsafe website: 
http://www.medsafe.govt.nz/profs/datasheet/b/breoelliptainhalation.pdf.
The study is considered low risk. The dose of FF/VI to be used in this study (100/25mcg) 
is an approved dose world-wide and has been administered on an out-patient basis in 
phase III studies in both asthma and chronic obstructive pulmonary disease (COPD) and 
was well tolerated.  The asthma patients to be included in this study are comparable to 
those in the asthma phase III studies.  There are some low risks associated with the study 
design and procedures and these are summarised below:

Risk Assessment
Potential Risk of Clinical Significance
Mitigation Strategy
Monitoring implemented
Investigational Product (IP)
There is a potential risk of worsening asthma as 
subjects will receive placebo in one treatment 
arm and no treatments during the washout 
periods (however access to SABA rescue 
medication will be available throughout the entire 
study).
Stopping criteria will be applied for both FEV1
(during the clinic stays/visits) and PEF (out-
patient and in-clinic) which will be monitored 
throughout the study treatment and washout 
periods.
Stopping criteria will be applied for both FEV1
(during the clinic stays) and PEF (out-patient and 
in-clinic) which will be monitored throughout the 
study treatment and washout periods.
As with any inhaled medication paradoxical 
bronchospasm may occur with an immediate 
wheeze after dosing.
If bronchospasm occurs following dosing, 
immediate administration of a short-acting (i.e., 
quick relief) inhaled bronchodilator (e.g., 
albuterol) is recommended. If this treatment fails 
to provide relief, a physician should be contacted 
immediately and/or emergency treatment should 
be sought.
First dose of the study medication in each 
treatment period will be administered in the clinic 
under the supervision of a physician.
FF/VI is contraindicated in subjects with severe 
milk protein allergy or known hypersensitivity or 
any ingredient of the preparation.
These subjects will be excluded from the study.
Not applicable.
Cardiovascular effects, such as cardiac 
arrhythmias e.g. supraventricular tachycardia 
and extrasystoles may be seen with 
sympathomimetic drugs, including fluticasone 
furoate/vilanterol. Therefore fluticasone 
furoate/vilanterol should be used with caution in 
patients with severe cardiovascular disease.
Caution is needed in patients with pre-existing 
cardiovascular (CV) disease, especially severe 
CV disease. Patients with severe CV disease will
be excluded.

Benefit Assessment
Benefit considerations for each individual subject may include:

Potential benefit of receiving FF/VI combined inhaled therapy during the study

Contributing to the process of developing new asthma therapies

Medical evaluations/assessments associated with study procedures e.g. PEF, 
FEV1, physical examinations and vital signs.
4.6.3.
Overall Benefit:Risk Conclusion
The study is considered low risk. The dose of FF/VI to be used in this study (100/25mcg) 
is an approved dose world-wide and has been administered on an out-patient basis in 
phase III studies in both asthma and COPD and was well tolerated.  The asthma patients 
to be included in this study are comparable to those in the asthma phase III studies.
Taking into account the measures taken to minimise risk to patients participating in this 
study, the potential low risks identified in association with inhaled FF/VI are justified by 
the anticipated benefits that will be afforded to subjects with asthma.

investigator or GSK Medical Monitor, contraindicates their participation.
5.3.
Screening Failures
Screen failures are defined as subjects who consent to participate in the clinical trial but 
are never subsequently randomized. In order to ensure transparent reporting of screen 
failure subjects, meet the Consolidated Standards of Reporting Trials (CONSORT) 
publishing requirements, and respond to queries from Regulatory authorities, a minimal 
set of screen failure information is required including Demography, Screen Failure 
details, Eligibility Criteria, and Serious Adverse Events (SAEs) (see Section 7.4.1.6).
Subjects who initially fail screening based on not meeting one of the inclusion/exclusion 
criteria may be rescreened subsequently. A limited rescreen checking this parameter 
against the inclusion/exclusion criteria may be performed, and if the subject then meets 
all the eligibility criteria, they would be allowed to be enrolled onto the study. However, 
repeat Day -7 visits cannot be performed.
5.4.
Withdrawal/Stopping Criteria
Worsening asthma: The following criteria will be used to aid the Investigator in 
determining asthma stability. A randomised subject who meets any of the following 
stopping criteria will be withdrawn from the study:

CONFIDENTIAL
201499
24

Clinic PEF and FEV1 below the stability limit values calculated at pre-treatment Day 
1, Treatment Period 1.  Subjects must have completed a minimum of at least 10 out 
of 14 peak flow measurements during the one week prior to randomisation (Day -7 
to Day 1).

During the study, the subject experienced:
1.
At least 4 consecutive days in which the PEF (either AM, PM or both) 
has fallen below the PEF Stability Limit calculated at pre-treatment Day 
1, Treatment Period 1 OR
2.
At least 3 days in which 12 inhalations/day of albuterol/salbutamol 
were used.

Subjects who experience a protocol-defined severe exacerbation, defined as 
deterioration of asthma requiring the use of systemic corticosteroids (tablets, 
suspension, or injection) for at least 3 days or an in-patient hospitalization or 
emergency department visit due to asthma that required systemic corticosteroids.

Clinical asthma worsening which in the opinion of the investigator requires 
additional asthma treatment other than study medication or study supplied albuterol/ 
salbutamol.
The following actions must be taken in relation to a subject who fails to attend the clinic 
for a required study visit:

The site must attempt to contact the subject and re-schedule the missed visit as soon 
as possible. 

The site must counsel the subject on the importance of maintaining the assigned visit 
schedule and ascertain whether or not the subject wishes to and/or should continue in 
the study. 

In cases where the subject is deemed ‘lost to follow up’, the investigator or designee 
must make every effort to regain contact with the subject (where possible, 3 
telephone calls and if necessary a certified letter to the subject’s last known mailing 
address or local equivalent methods). These contact attempts should be documented 
in the subject’s medical record. 

Should the subject continue to be unreachable, only then will he/she be considered to 
have withdrawn from the study with a primary reason of “Lost to Follow-up”. 
A subject may withdraw from study treatment at any time at his/her own request, or may 
be withdrawn at any time at the discretion of the investigator for safety, behavioural or 
administrative reasons. If a subject withdraws from the study, he/she may request 
destruction of any samples taken, and the investigator must document this in the site 
study records. 
5.5.
Subject and Study Completion

Blinding
This will be a double-blind study and the following will apply. 

The investigator or treating physician may unblind a subject’s treatment assignment 
only in the case of an emergency OR in the event of a serious medical condition 
when knowledge of the study treatment is essential for the appropriate clinical 
management or welfare of the subject as judged by the investigator. 

Investigators have direct access to the subject’s individual study treatment. 

It is preferred (but not required) that the investigator first contacts the Medical 
Monitor or appropriate GSK study personnel to discuss options before unblinding 
the subject’s treatment assignment. 

If GSK personnel are not contacted before the unblinding, the investigator must 
notify GSK as soon as possible after unblinding, but without revealing the treatment 
assignment of the unblinded subject, unless that information is important for the 
safety of subjects currently in the study. 

The date and reason for the unblinding must be fully documented in the CRF.
The patients, site staff and GSK will remain blinded for the duration of the study.
A subject will be withdrawn if the subject’s treatment code is unblinded by the 
investigator or treating physician. The primary reason for discontinuation (the event or 
condition which led to the unblinding) will be recorded in the CRF.

GSK’s Global Clinical Safety and Pharmacovigilance (GCSP) staff may unblind the 
treatment assignment for any subject with an SAE. If the SAE requires that an 
expedited regulatory report be sent to one or more regulatory agencies, a copy of the 
report, identifying the subject’s treatment assignment, may be sent to investigators in 
accordance with local regulations and/or GSK policy.
Sealed code break envelopes will be provided to the site, in case of unblinding.
6.4.
Packaging and Labeling
The contents of the label will be in accordance with all applicable regulatory 
requirements.
6.5.
Preparation/Handling/Storage/Accountability
No special preparation of study treatment is required.

Only subjects enrolled in the study may receive study treatment and only authorized 
site staff may supply or administer study treatment.  All study treatments must be 
stored in a secure environmentally controlled and monitored (manual or automated) 
area in accordance with the labelled storage conditions with access limited to the 
investigator and authorized site staff.


The investigator, institution, or the head of the medical institution (where applicable)
is responsible for study treatment accountability, reconciliation, and record 
maintenance (i.e. receipt, reconciliation and final disposition records).  

Further guidance and information for final disposition of unused study treatment are 
provided in the SRM.

Under normal conditions of handling and administration, study treatment is not 
expected to pose significant safety risks to site staff.  Take adequate precautions to 
avoid direct eye or skin contact and the generation of aerosols or mists. In the case of 
unintentional occupational exposure notify the monitor, Medical Monitor and/or
GSK study contact.

A Material Safety Data Sheet (MSDS)/equivalent document describing occupational 
hazards and recommended handling precautions either will be provided to the 
investigator, where this is required by local laws, or is available upon request from 
GSK.
6.6.
Compliance with Study Treatment Administration
When subjects are dosed at the site (on Day 1 and Day 14 of each treatment period), they 
will receive study treatment directly from the investigator or designee, under medical 
supervision.  The date and time of each dose administered in the clinic will be recorded in 
the source documents.  The dose of study treatment and study subject identification will 
be confirmed at the time of dosing by a member of the study site staff other than the 
person administering the study treatment.  
When subjects self-administer study treatment at home (on Days 2 to 13 of each 
treatment period), dosing details will be completed by the subjects in individual paper
diaries, and then later transcribed by the site into the CRF. Dosing compliance will be 
assessed through querying the subject during the subsequent site visits and this will be 
documented in the source documents and CRF.  A dosing record for each subject must be 
maintained and reconciled with study treatment and compliance records.
Subject compliance with study treatment administered at home will be reinforced by the 
site using various methods including the use of daily text reminders and weekly 
telephone contact. More details will be given in the SRM.
6.7.
Treatment of Study Treatment Overdose
An overdose for this study will be considered as any dose of study drug more than the 
planned dose on each dosing occasion. In the event of an overdose, there are no 
recommended medications or non-drug therapies for treatment. GSK is not 
recommending specific treatment guidelines for overdose and toxicity management. The 
investigator should contact the GSK Medical Monitor, and is advised to refer to the 
relevant documents for detailed information regarding warnings, precautions, 
contraindications, adverse events, and other significant data pertaining to the study 
drug(s) being used in this study. Such documents may include, but not limited to, the 
Investigator’s Brochure (IB) or equivalent document provided by GSK, the approved 
product label if applicable, or both. Clinical judgment should be used in treating the 


2015N241692_00
CONFIDENTIAL

28
overdose. Management should be supportive and the investigator should use his/her 
clinical judgement in treating any overdose situation.  Subjects experiencing such adverse 
events will be followed up clinically until the event has resolved.
6.8.
Treatment after the End of the Study
Subjects will not receive any additional treatment from GSK after completion of the 
study because the indication being studied is not life threatening or seriously debilitating 
and/or other treatment options are available.
The investigator is responsible for ensuring that consideration has been given to the post-
study care of the subject’s medical condition, whether or not GSK is providing specific 
post-study treatment.

Screening and Critical Baseline Assessments
Cardiovascular medical history/risk factors (as detailed in the CRF) will be assessed at 
screening.
The following demographic parameters will be captured: year of birth, sex, race and 
ethnicity.
Medical/medication/family history will be assessed as related to the inclusion/exclusion 
criteria listed in Section 5.  
7.3.
Pharmacodynamics
7.3.1.
FeNO measurements
Fractionated exhaled nitric oxide (FeNO) measurements will be collected from 7 days 
before Day 1 (start of treatment) (Day -7), and then every morning and evening all the 
way through to Day 35 of each treatment period (see Time and Events Table in Section 
7.1).  Additional time points may be added during the course of the study based on newly 
available information.
Single FeNO measurements will be collected at each time-point in accordance with 
ATS/ERS guidelines. These measurements will be recorded using a NIOX Vero device
which will be supplied to the patient on Day -7 by the site. Measurements will be 
captured electronically and regularly downloaded by the site at each clinic visit.
Training and practice with these devices will be given to each patient at the screening 
visit.
More details will be given in the SRM.
7.3.2.
Spirometry
Three technically acceptable FEV1 measurements will be made at the time points outlined 
in the Time and Events table (Section 7.1) and the highest values will be recorded.
Spirometry assessments must be performed in accordance with ATS/ERS guidelines 
[ATS/ERS Task Force, 2005]. The Forced Expiratory Volume during the first 6 seconds 
(FVC6), rather than the full Forced Vital Capacity (FVC) will be measured.
Screening FEV1 must be measured between 7am-10am.
7.3.2.1.
Reversibility testing
The presence of reversible airways disease can have been demonstrated historically 
within 6 months of the screening visit.
OR
It must be demonstrated at the screening visit.


2015N241692_00
CONFIDENTIAL
201499

Following the spirometry assessment at screening, administer a single dose of 400 g 
inhaled albuterol / salbutamol using a metered dose inhaler (MDI) and spacer device.  
The bronchodilator will be withheld for 6 hours prior to the screening visit. At any time 
point between 15 and 30 minutes post administration of albuterol / salbutamol, take 
triplicate FEV1 measurements and record the highest.
Reversibility is shown if there is an increase in FEV1 of 12.0% over baseline and an 
absolute change of 200 mL between the highest pre and post salbutamol FEV1.
7.3.2.2.
FEV1 Stability Limit
Calculate a FEV1 Stability Limit as follows:
Best pre-dose FEV1 x 80%
The FEV1 Stability Limit value will be calculated at the pre-dose time point of treatment 
period 1 and used as reference until the pre-dose time point of treatment period 2. The 
stability limit will be re-calculated at the pre-dose time point of treatment period 2 and
used for the remainder of the study.
7.3.3.
PEF
Each subject will be given a PEF meter by the site on Day -7. Data will be captured 
electronically.
Subjects must measure morning and evening PEF as indicated in the time and events 
table. Three technically acceptable PEF measurements will be collected at each time 
point and the highest values will be recorded.
7.3.3.1.
PEF Stability Limit
Subjects must have completed a minimum of at least 10 out of 14 peak flow 
measurements during the one week prior to randomisation (Day -7 to Day 1).
Calculate a PEF Stability Limit as follows:
Mean AM PEF from the available 7 days preceding Day 1 dose x 80%
The AM PEF from the morning of Day 1 will be included in the calculation of the PEF 
stability limit.
The PEF Stability Limit value will be used for the remainder of the study.
PEF devices will be set to alert the subject if their PEF drops below this limit.
7.3.3.2.
PEF below Stability Limit
Should the PEF fall below the PEF stability limit, the subject should contact the site. The 
investigator must monitor the subject and withdraw the subject is he/she meets any of the 
criteria in Section 5.4.

Safety
Planned time points for all safety assessments are listed in the Time and Events Table 
(Section 7.1).  Additional time points for safety tests (such as vital signs and physical 
examinations) may be added during the course of the study based on newly available data 
to ensure appropriate safety monitoring.
7.4.1.
Adverse Events (AE) and Serious Adverse Events (SAEs)
The definitions of an AE or SAE can be found in Appendix 2.
The investigator and their designees are responsible for detecting, documenting and 
reporting events that meet the definition of an AE or SAE. 
7.4.1.1.
Time period and Frequency for collecting AE and SAE information

Any SAEs assessed as related to study participation (e.g., protocol-mandated 
procedures, invasive tests, or change in existing therapy) or related to a GSK product 
will be recorded from the time a subject consents to participate in the study up to and 
including any follow-up contact. 

AEs will be collected from the start of the run-in period (Day -7) until the follow-up 
contact (see Section 7.4.1.3), at the time-points specified in the Time and Events 
Table (Section 7.1).

Medical occurrences that begin prior to the start of study treatment but after 
obtaining informed consent may be recorded on the Medical History/Current 
Medical Conditions section of the CRF.

All SAEs will be recorded and reported to GSK within 24 hours, as indicated in 
Appendix 2.

Investigators are not obligated to actively seek AEs or SAEs in former study 
subjects. However, if the investigator learns of any SAE, including a death, at any 
time after a subject has been discharged from the study, and he/she considers the 
event reasonably related to the study treatment or study participation, the investigator 
must promptly notify GSK.
NOTE: The method of recording, evaluating and assessing causality of AEs and SAEs 
plus procedures for completing and transmitting SAE reports to GSK are provided in 
Appendix 2.
7.4.1.2.
Method of Detecting AEs and SAEs
Care will be taken not to introduce bias when detecting AEs and/or SAEs. Open-ended 
and non-leading verbal questioning of the subject is the preferred method to inquire about 
AE occurrence.  Appropriate questions include:

“How are you feeling?”

“Have you had any (other) medical problems since your last visit/contact?”


2015N241692_00
CONFIDENTIAL
201499
36

“Have you taken any new medicines, other than those provided in this study, since 
your last visit/contact?”
7.4.1.3.
Follow-up of AEs and SAEs
After the initial AE/SAE report, the investigator is required to proactively follow each 
subject at subsequent visits/contacts.  All SAEs, and non-serious AEs of special interest 
(as defined in Section 4.6.1) will be followed until resolution, until the condition 
stabilizes, until the event is otherwise explained, or until the subject is lost to follow-up 
(as defined in Section 5.4). Further information on follow-up procedures is given in 
Appendix 2.
7.4.1.4.
Cardiovascular and Death Events
Investigators will be required to fill out event specific data collection tools for the
following AEs and SAEs:

Myocardial infarction/unstable angina

Congestive heart failure

Arrhythmias

Valvulopathy

Pulmonary hypertension

Cerebrovascular events/stroke and transient ischemic attack

Peripheral arterial thrombosis

Deep Venous Thrombosis

Revascularization
For these cardiovascular events detailed above and for all deaths, whether or not they are 
considered SAEs, specific Cardiovascular (CV) and Death sections of the CRF will be 
required to be completed. These sections include questions regarding cardiovascular 
(including sudden cardiac death) and non-cardiovascular death. 
The CV CRFs 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 CRF 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.
7.4.1.5.
Disease-Related Events and/or Disease-Related Outcomes Not 
Qualifying as SAEs
The following disease related events (DREs) are common in subjects with asthma and 
can be serious/life threatening:


2015N241692_00
CONFIDENTIAL
201499
37
1.
Wheezing
2.
Chest tightness or chest heaviness
3.
Coughing
Because these events are typically associated with the disease under study, they will not 
be reported according to the standard process for expedited reporting of SAEs to GSK 
(even though the event may meet the definition of a SAE).  These events will be recorded 
on the DRE page in the subject’s CRF within 5 working days.
NOTE: However, if either of the following conditions apply, then the event must be 
recorded and reported as an SAE (instead of a DRE): 

The event is, in the investigator’s opinion, of greater intensity, frequency, or 
duration than expected for the individual subject, or

The investigator considers that there is a reasonable possibility that the event 
was related to treatment with the investigational product
7.4.1.6.
Regulatory Reporting Requirements for SAEs
Prompt notification by the investigator to GSK of SAEs related to study treatment (even 
for non- interventional post-marketing studies) is essential so that legal obligations and 
ethical responsibilities towards the safety of subjects and the safety of a product under 
clinical investigation are met. 
GSK has a legal responsibility to notify both the local regulatory authority and other 
regulatory agencies about the safety of a product under clinical investigation.  GSK will 
comply with country specific regulatory requirements relating to safety reporting to the 
regulatory authority, Institutional Review Board (IRB)/Independent Ethics Committee 
(IEC) and investigators.
Investigator safety reports are prepared for suspected unexpected serious adverse 
reactions according to local regulatory requirements and GSK policy and are forwarded 
to investigators as necessary.
An investigator who receives an investigator safety report describing a SAE(s) or other 
specific safety information (e.g., summary or listing of SAEs) from GSK will file it with 
the IB and will notify the IRB/IEC, if appropriate according to local requirements.
7.4.2.
Pregnancy

Details of all pregnancies in female subjects and female partners of male subjects 
will be collected after the start of dosing and until the follow-up visit.

If a pregnancy is reported then the investigator should inform GSK within 2 weeks 
of learning of the pregnancy and should follow the procedures outlined in Appendix
3.

A complete physical examination will include, at a minimum, assessment of the 
Cardiovascular, Respiratory, Gastrointestinal and Neurological systems. Height and 
weight will also be measured and recorded.

Investigators should pay special attention to clinical signs related to previous serious 
illnesses
7.4.4.
Vital Signs

Vital signs will be measured in semi-supine position after 5 minutes rest and will 
include temperature, systolic and diastolic blood pressure (BP) and pulse rate. 
7.4.5.
Clinical Safety Laboratory Assessments
All protocol required laboratory assessments as detailed in Table 1 must be conducted in 
accordance with the Laboratory Manual, and Protocol Time and Events Schedule.
Laboratory requisition forms must be completed and samples must be clearly labelled
with the subject number, protocol number, site/centre number, and visit date. Reference 
ranges for all safety parameters will be provided to the site by the laboratory responsible 
for the assessments.
If additional non-protocol specified laboratory assessments are performed at the 
institution’s local laboratory and result in a change in subject management or are 
considered clinically significant by the investigator (e.g., SAE or AE or dose 
modification) the results must be recorded in the CRF.
Parameters to be tested are listed in Table 1.

Exploratory Biomarkers
With the subject’s consent, blood samples will be collected during this study and used for 
the purposes of measuring exploratory biomarkers, including but not limited to, blood 
eosinophil and serum periostin levels on Day 1 pre-dose (baseline) and following inhaled 
administration of FF/VI.
Samples will be collected at the time-points indicated in the Time and Events Table in 
Section 7.1. The timing of the collections may be adjusted on the basis of emerging data 
from this study or other new information in order to ensure optimal evaluation of the PD 
endpoints. Analyses of these biomarker data may be reported separately. Further details 
will be provided in the SRM.

DATA MANAGEMENT

For this study, subject data will be entered into GSK defined CRFs, transmitted 
electronically to GSK or designee and combined with data provided from other 
sources in a validated data system.

Subject paper diaries will also be used for when the subjects are at home, for 
collection of dosing information, details of any AEs/SAEs and concomitant 
medications.  These will then be transcribed into the CRF by clinic staff.

Management of clinical data will be performed in accordance with applicable GSK 
standards and data cleaning procedures to ensure the integrity of the data, e.g., 
removing errors and inconsistencies in the data.

Adverse events and concomitant medications terms will be coded using MedDRA 
(Medical Dictionary for Regulatory Activities) and an internal validated medication 
dictionary, GSKDrug.  

CRFs (including queries and audit trails) will be retained by GSK, and copies will be 
sent to the investigator to maintain as the investigator copy.  Subject initials will not 
be collected or transmitted to GSK according to GSK policy.

STATISTICAL CONSIDERATIONS AND DATA 
ANALYSES
9.1.
Hypotheses
No formal hypothesis will be tested, an estimation approach will be adopted to address 
the primary objective. A point estimate and corresponding 95% CI will be constructed for 
the treatment ratio of test treatment, (test) and reference treatment(reference), where 
FF/VI 100/25mcg is the test treatment and placebo the reference treatment.

Sample Size Considerations
9.2.1.
Sample Size Assumptions
Approximately 28 subjects will be recruited to ensure 24 evaluable subjects.  An 
evaluable subject is defined as a subject who completes dosing and critical assessments in 
both treatment periods.
A re-analysis of FeNO data from the FFA10028 study [GlaxoSmithKline Document 
Number GM2003/00418/00] was carried out to estimate the within-subject coefficient of 
variation (CVw) from a repeated measures analysis using the treatments and time-points 
most relevant to this study (i.e. FF and placebo treatments and all pre-dose, 12 hour and 
24 hour time-points on all days assessed (Days 1-5).  A mixed effects repeated measures 
model was fitted with fixed effect terms for period, treatment, day, time, period-level 
baseline, subject-level baseline, (period-level baseline)*day*time interaction term and the 
treatment*day*time interaction term. Day*time interaction term was fitted as a repeated 
measure.  FeNO was loge-transformed prior to deriving subject-level baseline and period-
level baseline.  The CVw from the re-analysis was 21.6%.
Based upon a CVw of 21.6% and a sample size of 24 subjects, it is estimated that the 
lower and upper bounds of the 95% confidence interval for the treatment ratio (FF/VI vs 
Placebo) for FeNO will be approximately 14% of the point estimate.
9.2.2.
Sample Size Sensitivity
A sensitivity analysis was conducted in the event that the variability deviates from that 
estimated from the FFA10028 study [GlaxoSmithKline Document Number 
GM2003/00418/00]. The table below shows precision estimates for varying within 
subject coefficient of variability keeping all other variables constant.

Data Analysis Considerations
9.3.1.
Analysis Populations
Statistical analyses of the pharmacodynamic parameter data will be the responsibility of 
Clinical Statistics, GlaxoSmithKline.
Subjects excluded from any analyses will be fully documented and justified within the 
clinical study report. All analyses will be based on the actual treatment that each subject 
received. Any departures from the planned treatment according to the randomisation 
schedule will be documented in the clinical study report.
The ‘All Subjects’ population will consist of all subjects randomised to treatment who 
received at least one dose of study treatment.
The ‘Pharmacodynamic’ (PD) population will consist of all subjects from the ‘All 
Subjects’ population who had at least one PD assessment.
9.3.2.
Interim Analysis
No interim analysis is planned.
9.4.
Key Elements of Analysis Plan
9.4.1.
Primary Analyses
Following loge-transformation, primary endpoint of FeNO change from baseline ratio
following cessation of treatment will be analyzed using a mixed effects repeated 
measures model with fixed effect terms for period, treatment, day, time, (period-level 
baseline)*day*time interaction term, treatment*day*time interaction term, period-level 
baseline and subject-level baseline. Day*time interaction term will be fitted as repeated 
measure. FeNO will be loge-transformed prior to deriving subject-level baseline and 
period-level baseline.  Point estimates and their associated 95% confidence intervals will 
be constructed for the difference [FF/VI 100/25mcg] – [Placebo] at each timepoint 
(AM/PM i.e. pre-dose & 12 hours) on each day. The point estimates and their associated 
95% confidence intervals will then be back-transformed to provide point estimates and 
95% confidence intervals for the ratios, [FF/VI 100/25mcg]/[Placebo] for each day and 
AM/PM timepoint. Further details will be provided in the Reporting and Analysis Plan
(RAP) regarding the model to be fitted and model checking.
9.4.2.
Secondary Analyses
Secondary endpoints of FeNO change from baseline ratio during treatment and FEV1 will 
be analysed similarly to the primary FeNO endpoint.  FEV1 will not be log-transformed.
PEF data will be listed and summarised.
Further details will be provided in the RAP.

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

12.2.
Appendix 2: Definition of and Procedures for Recording, 
Evaluating, Follow-Up and Reporting of Adverse Events
12.2.1.
Definition of Adverse Events
Adverse Event Definition:

An AE is any untoward medical occurrence in a patient or clinical investigation 
subject, temporally associated with the use of a medicinal product, whether or not 
considered related to the medicinal product.

NOTE: An AE can therefore be any unfavorable and unintended sign (including an 
abnormal laboratory finding), symptom, or disease (new or exacerbated) temporally 
associated with the use of a medicinal product.
Events meeting AE definition include:

Any abnormal laboratory test results (hematology, clinical chemistry, or urinalysis) 
or other safety assessments (e.g., ECGs, radiological scans, vital signs 
measurements), including those that worsen from baseline, and felt to be clinically 
significant in the medical and scientific judgement of the investigator.

Exacerbation of a chronic or intermittent pre-existing condition including either an 
increase in frequency and/or intensity of the condition.

New conditions detected or diagnosed after study treatment administration even 
though it may have been present prior to the start of the study.

Signs, symptoms, or the clinical sequelae of a suspected interaction.

Signs, symptoms, or the clinical sequelae of a suspected overdose of either study 
treatment or a concomitant medication (overdose per se will not be reported as an 
AE/SAE unless this is an intentional overdose taken with possible suicidal/self-
harming intent.  This should be reported regardless of sequelae).
Events NOT meeting definition of an AE include:

Any clinically significant abnormal laboratory findings or other abnormal safety 
assessments which are associated with the underlying disease, unless judged by the 
investigator to be more severe than expected for the subject’s condition.

The disease/disorder being studied or expected progression, signs, or symptoms of 
the disease/disorder being studied, unless more severe than expected for the subject’s 
condition.

Medical or surgical procedure (e.g., endoscopy, appendectomy): the condition that 
leads to the procedure is an AE.

Situations where an untoward medical occurrence did not occur (social and/or 


2015N241692_00
CONFIDENTIAL
201499
50
convenience admission to a hospital).

Anticipated day-to-day fluctuations of pre-existing disease(s) or condition(s) present 
or detected at the start of the study that do not worsen.
12.2.2.
Definition of Serious Adverse Events
If an event is not an AE per definition above, then it cannot be an SAE even if serious 
conditions are met (e.g., hospitalization for signs/symptoms of the disease under study, 
death due to progression of disease, etc).
Serious Adverse Event (SAE) is defined as any untoward medical occurrence that, 
at any dose:
a.
Results in death
b.
Is life-threatening
NOTE:
The term 'life-threatening' in the definition of 'serious' refers to an event in which the 
subject was at risk of death at the time of the event.  It does not refer to an event, which 
hypothetically might have caused death, if it were more severe.
c.
Requires hospitalization or prolongation of existing hospitalization
NOTE:

In general, hospitalization signifies that the subject has been detained (usually 
involving at least an overnight stay) at the hospital or emergency ward for 
observation and/or treatment that would not have been appropriate in the physician’s 
office or out-patient setting.  Complications that occur during hospitalization are 
AEs.  If a complication prolongs hospitalization or fulfills any other serious criteria, 
the event is serious.  When in doubt as to whether “hospitalization” occurred or was 
necessary, the AE should be considered serious.

Hospitalization for elective treatment of a pre-existing condition that did not worsen 
from baseline is not considered an AE.
d.
Results in disability/incapacity
NOTE:

The term disability means a substantial disruption of a person’s ability to conduct 
normal life functions.

This definition is not intended to include experiences of relatively minor medical 
significance such as uncomplicated headache, nausea, vomiting, diarrhea, influenza, 
and accidental trauma (e.g. sprained ankle) which may interfere or prevent everyday 
life functions but do not constitute a substantial disruption


2015N241692_00
CONFIDENTIAL
201499
51
e.
Is a congenital anomaly/birth defect
f.
Other situations:

Medical or scientific judgment should be exercised in deciding whether reporting is 
appropriate in other situations, such as important medical events that may not be 
immediately life-threatening or result in death or hospitalization but may jeopardize 
the subject or may require medical or surgical intervention to prevent one of the 
other outcomes listed in the above definition. These should also be considered 
serious.

Examples of such events are invasive or malignant cancers, intensive treatment in an 
emergency room or at home for allergic bronchospasm, blood dyscrasias or 
convulsions that do not result in hospitalization, or development of drug dependency 
or drug abuse
g.
Is associated with liver injury and impaired liver function defined as:

ALT 3xULN and total bilirubin* 2xULN (>35% direct), or

ALT 3xULN and INR** > 1.5.
* Serum bilirubin fractionation should be performed if testing is available; if unavailable, 
measure urinary bilirubin via dipstick.  If fractionation is unavailable and ALT 3xULN 
and total bilirubin 2xULN, then the event is still to be reported as an SAE.
** INR testing not required per protocol and the threshold value does not apply to 
subjects receiving anticoagulants.  If INR measurement is obtained, the value is to be 
recorded on the SAE form.
12.2.3.
Definition of Cardiovascular Events
Cardiovascular Events (CV) Definition:
Investigators will be required to fill out the specific CV event page of the CRF for the 
following AEs and SAEs:

Myocardial infarction/unstable angina

Congestive heart failure

Arrhythmias

Valvulopathy

Pulmonary hypertension

Cerebrovascular events/stroke and transient ischemic attack

Peripheral arterial thromboembolism

Deep venous thrombosis/pulmonary embolism

201499
52

Revascularization
12.2.4.
Recording of AEs and SAEs
AEs and SAE Recording:

When an AE/SAE occurs, it is the responsibility of the investigator to review all 
documentation (e.g., hospital progress notes, laboratory, and diagnostics reports) 
relative to the event.

The investigator will then record all relevant information regarding an AE/SAE in 
the CRF

It is not acceptable for the investigator to send photocopies of the subject’s medical 
records to GSK in lieu of completion of the GSK, AE/SAE CRF page.

There may be instances when copies of medical records for certain cases are 
requested by GSK.  In this instance, all subject identifiers, with the exception of the 
subject number, will be blinded on the copies of the medical records prior to 
submission of to GSK.

The investigator will attempt to establish a diagnosis of the event based on signs, 
symptoms, and/or other clinical information.  In such cases, the diagnosis will be 
documented as the AE/SAE and not the individual signs/symptoms.
12.2.5.
Evaluating AEs and SAEs
Assessment of Intensity
The investigator will make an assessment of intensity for each AE and SAE reported 
during the study and will assign it to one of the following categories:

Mild:  An event that is easily tolerated by the subject, causing minimal discomfort 
and not interfering with everyday activities.

Moderate:  An event that is sufficiently discomforting to interfere with normal 
everyday activities

Severe:  An event that prevents normal everyday activities. - an AE that is assessed 
as severe will not be confused with an SAE. Severity is a category utilized for rating 
the intensity of an event; and both AEs and SAEs can be assessed as severe.

An event is defined as ‘serious’ when it meets at least one of the pre-defined 
outcomes as described in the definition of an SAE.
Assessment of Causality

The investigator is obligated to assess the relationship between study treatment and 


2015N241692_00
CONFIDENTIAL
201499
53
the occurrence of each AE/SAE.

A "reasonable possibility" is meant to convey that there are facts/evidence or 
arguments to suggest a causal relationship, rather than a relationship cannot be ruled 
out.

The investigator will use clinical judgment to determine the relationship.

Alternative causes, such as natural history of the underlying diseases, concomitant 
therapy, other risk factors, and the temporal relationship of the event to the study 
treatment will be considered and investigated.

The investigator will also consult the Investigator Brochure (IB) and/or Product 
Information, for marketed products, in the determination of his/her assessment.

For each AE/SAE the investigator must document in the medical notes that he/she 
has reviewed the AE/SAE and has provided an assessment of causality.

There may be situations when an SAE has occurred and the investigator has minimal 
information to include in the initial report to GSK.  However, it is very important 
that the investigator always make an assessment of causality for every event 
prior to the initial transmission of the SAE data to GSK.

The investigator may change his/her opinion of causality in light of follow-up 
information, amending the SAE data collection tool accordingly.

The causality assessment is one of the criteria used when determining regulatory 
reporting requirements.
Follow-up of AEs and SAEs

The investigator is obligated to perform or arrange for the conduct of supplemental 
measurements and/or evaluations as may be indicated or as requested by GSK to 
elucidate as fully as possible the nature and/or causality of the AE or SAE.

The investigator is obligated to assist.  This may include additional laboratory tests 
or investigations, histopathological examinations or consultation with other health 
care professionals.

If a subject dies during participation in the study or during a recognized follow-up 
period, the investigator will provide GSK with a copy of any post-mortem findings, 
including histopathology.

New or updated information will be recorded in the originally completed CRF.

The investigator will submit any updated SAE data to GSK within the designated 
reporting time frames.

12.2.6.
Reporting of SAEs to GSK
SAE reporting to GSK via electronic data collection tool

Primary mechanism for reporting SAEs to GSK will be the electronic data collection 
tool

If the electronic system is unavailable for greater than 24 hours, the site will use the 
paper SAE data collection tool and fax it to the Medical Monitor and the GSK Study 
Manager

Site will enter the serious adverse event data into the electronic system as soon as it 
becomes available.

The investigator will be required to confirm review of the SAE causality by ticking 
the ‘reviewed’ box at the bottom of the eCRF page within 72 hours of submission of 
the SAE.

After the study is completed at a given site, the electronic data collection tool (e.g., 
InForm system) 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 subject or receives updated data 
on a previously reported SAE after the electronic data collection tool has been taken 
off-line, the site can report this information on a paper SAE form or to the Medical 
Monitor or the GSK Study Manager by telephone.

Contacts for SAE receipt can be found at the beginning of this protocol on the 
Sponsor/Medical Monitor Contact Information page.

Collection of Pregnancy Information

Investigator will collect pregnancy information on any female subject, who becomes 
pregnant while participating in this study

Information will be recorded on the appropriate form and submitted to GSK within 2 
weeks of learning of a subject's pregnancy.

Subject will be followed to determine the outcome of the pregnancy. The 
investigator will collect follow up information on mother and infant, 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 2. While the investigator is not obligated to actively seek 
this information in former study participants, he or she may learn of an SAE through 
spontaneous reporting.
Any female subject who becomes pregnant while participating 

will discontinue study medication or be withdrawn from the study.

Investigator will attempt to collect pregnancy information on any female partner of a 
male study subject who becomes pregnant while participating in this study.  This 
applies only to subjects who are randomized to receive study medication. 

After obtaining the necessary signed informed consent from the female partner 
directly, the investigator will record pregnancy information on the appropriate form 
and submit it to GSK within 2 weeks 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.

Overview
Key Elements of the RAP
Exploratory
Objective / 
Endpoint
To investigate the effect of repeat administration of FF/VI 100/25mcg 
combination on exploratory biomarkers, including but not limited to, blood 
eosinophil levels and serum periostin levels, in comparison with placebo in 
subjects with asthma as measured by:

Measurement of exploratory biomarkers, including but not 
limited to, blood eosinophil and serum periostin levels at baseline, and 
at various time points after cessation of repeat dose treatment with 
FF/VI
Study 
Design
Randomised, double blind, placebo-controlled, two-period, crossover 
repeat dose study in adult subjects with asthma. 
Approximately twenty eight adult asthmatic subjects will be enrolled to 
ensure 24 subjects complete dosing and critical assessments for both 
treatment periods.
Each subject will participate in two treatment periods of 14 (+ 2 days).  
FF/VI 100/25mcg will be received once daily (AM dosing) in one period 
and placebo (AM dosing) will be administered in the other period. At the 
end of each treatment period , there will be a monitoring period of 21 days.  
Following the 21 day monitoring period following treatment period 1, there 
may be a period of up to a further 4 weeks before the subjects start 
treatment period 2. 
Planned 
Analyses

No interim analysis is planned.

The final planned analyses will be performed after database freeze has 
been declared.
Analysis 
Population

All Subjects Population comprise of all subjects randomised to 
treatment who received at least one dose of study medication

Pharmacodynamic Population comprise of all  Subjects in the 
‘All Subjects’ population who had at least one PD assessment
Hypothesis
No formal hypothesis will be tested, an estimation approach will be 
adopted to address the primary objective. A point estimate and 
corresponding 95% CI will be constructed for the treatment ratio of test 
treatment, μ(test) and reference treatment, µ(reference), where FF/VI 
100/25mcg is the test treatment and placebo the reference treatment
Primary 
Analyses
FeNO, change from baseline ratio will be formally analysed following loge-
transformation.  A mixed effects repeated measures model will be fitted 
with fixed effect terms for period, treatment, day, time, (period-level 
baseline)*day*time interaction term, treatment*day*time interaction term, 
period-level baseline and subject-level baseline. Day*time interaction term 
will be fitted as repeated measure. FeNO will be loge-transformed prior to 
deriving subject-level baseline and period-level baseline.


Change from baseline ratio of loge transformed FeNO over time following the 
cessation of repeat dose treatment with FF/VI.
Model Specification
Endpoints will be statistically analysed using a mixed models repeated measures 
(MMRM) model.
Terms fitted in the MMRM model will include:
Fixed effect terms: Period, Treatment, Day, Time, Period-level baseline*Day*Time 
interaction term, Treatment*Day*Time interaction term, Period-level baseline and 
Subject-level baseline. 
Repeated: Day*Time interaction term.
Note: FeNO will be loge-transformed prior to deriving subject-level baseline and period-
level baseline.
Model Checking & Diagnostics

Refer to Appendix 8: Model Checking and Diagnostics will be performed for 
mentioned Statistical Analyses as required.
Model Results Presentation

Point estimates and their associated 95% confidence intervals will be constructed for 
the difference [FF/VI 100/25mcg] – [Placebo] at each timepoint (AM and PM i.e. 
pre-dose & 12 hours) on each day. The point estimates and their associated 95% 
confidence intervals will then be back-transformed to provide point estimates and 
95% confidence intervals for the ratios, [FF/VI 100/25mcg]/[Placebo] for each day 
and AM/PM timepoint.

Estimates of within-subject variability for FeNO will also be provided, where 
CVw(%) = SQRT(exp(MSE) – 1)×100 and MSE is the residual mean squared error 
from the model. CVw represents a pooled measure of within-subject variability across 
the regimens FF/VI 100/25mcg, Placebo and timepoints.

Multiple Measurements at One 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 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.
Study Day

Calculated as the number of days from randomisation date :

Ref Date = Missing                     → Study Day = Missing 

Ref Date < Treatment start Date → Study Day = Ref Date – Treatment start Date    

Ref Data ≥ Treatment start Date → Study Day = Ref Date – (Treatment start
Date) + 1

Demographics
Age

GSK standard IDSL algorithms will be used for calculating age where birth date will 
be imputed as follows:
o
Any subject with a missing day will have this imputed as day ‘15’. 
o
Any subject with a missing date and month will have this imputed as ‘30th June’.

Birth date will be presented in listings as ‘YYYY’.
Body Mass Index (BMI)

Calculated as Weight (kg) / [Height (m)2]
Extent of Exposure

Number of days of exposure to study drug will be calculated based on the formula:  
Duration of Exposure in Days = (Treatment Stop Date – Treatment Start Date) + 1

Subjects who were randomized but did not report a treatment start date will be 
categorised as having zero days of exposure. 

The cumulative dose will be based on the formula:
Cumulative Dose = Sum of (Number of Days x Total Daily Dose)

Laboratory Parameters

If a laboratory value which is expected to have a numeric value for summary purposes, 
has a non-detectable level reported in the database, where the numeric value is 
missing, but typically a character value starting with ‘<x’ or ‘>x’ (or indicated as less 
than x or greater than x in the comment field) is present, the number of significant 
digits in the observed values will be used to determine how much to add or subtract in 
order to impute the corresponding numeric value. 
o
Example 1: 2 Significant Digits =  ‘< x ‘ becomes x – 0.01
o
Example 2: 1 Significant Digit   =  ‘> x’ becomes x + 0.1

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 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: Treatment States and Phases.
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.

will remain missing, with no imputation applied.
11.7.2.2.
Handling of Partial Dates
Element
Reporting Detail
Concomitant 
Medications

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.
Adverse 
Events

Any partial dates for adverse events will be raised to data management. 
If the full date cannot be ascertained, the following assumptions will be 
made:
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
However, if these results in a date prior to Week 1 Day 1 and the 
event could possibly have occurred during treatment from the 
partial information, then the Week 1 Day 1 date will be assumed to 
be the start date. 
o
The AE will then be considered to start on-treatment (worst case).
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.

Statistical Analysis Assumptions
Endpoint(s)

Loge (FeNO) and FEV1
Analysis

MMRM

Model assumptions will be applied, but appropriate adjustments maybe made based 
on the data.

The Kenward and Roger method for approximating the denominator degrees of 
freedom and correcting for bias in the estimated variance-covariance of the fixed 
effects will be used.

An unstructured covariance structure for the R matrix will be used by specifying 
‘type=UN’ on the REPEATED line.
o
In the event that this model fails to converge, alternative correlation structures 
may be considered such as CSH or CS. 
o
Akaike's Information Criteria (AIC) will be used to assist with the selection of 
covariance structure.

Distributional assumptions underlying the model used for analysis will be examined 
by obtaining a normal probability plot of the residuals and a plot of the residuals 
versus the fitted values (i.e. checking the normality assumption and constant variance 
assumption of the model respectively) to gain confidence that the model assumptions
