Amendment No. 1
This protocol amendment was created to include an additional exercise challenge 
procedure at 23 hours after the first dose of double-blinded study medication in each 
Treatment Period. The purpose is to demonstrate that inhaled Fluticasone 
Furoate/Vilanterol (FF/VI)100/25 mcg provides improved bronchoprotection against 
exercise-induced bronchoconstriction (EIB) compared with Fluticasone Propionate (FP) 
250 mcg after 23 hours of treatment with blinded medication. In addition, it will allow for 
an evaluation of the presence and extent of tachyphylaxis. Separately, the study title was 
revised to indicate the study is a ‘randomised’ study with a ‘crossover’ design. Other 
minor corrections and edits were also made.

2015-DEC-16
Amendment No. 2
This protocol is being amended to increase the screen failure rate to 20% (from 10%) and 
the run-in failure rate to 70% (from 55%). This takes into consideration the challenge of 
enrolling EIB subjects with Symptomatic Allergic Rhinitis (SAR) at screening and also 
the challenge for subjects to demonstrate a decrease in FEV1 of ≥20% at one time point 
within 30 minutes of the end of the exercise challenge at Visit 2; after taking fluticasone 
propionate for approximately four weeks during the run-in period. The amendment also 
allows subjects with symptomatic allergic rhinitis at screening to be treated with 
intranasal corticosteroids for up to four weeks, followed by a repeat screening visit to 
determine eligibility prior to entry into the study. Subjects with symptomatic allergic 
rhinitis during the study may be treated with intranasal corticosteroids at a constant dose 
for the duration of the study. 
The time window for the repeat exercise challenge has been extended from 24-48 hours 
to up to one week; taking into consideration the challenge for subjects to return within 48 
hours for a repeat procedure.
The ACT questionnaire has been replaced by the ACQ-5 questionnaire given the 
mismatch between treatment periods of two weeks and the recall period of 4 weeks for 
the ACT.
Tobacco/marijuana use and pregnancy (which were omitted in error in the original 
protocol) have been added as exclusion criteria.
The secondary endpoint for time to recovery has been changed to a binary endpoint 
defining recovery as those subjects who have a 30 minute post-exercise FEV1
measurement that is no more than 5% lower than their pre-exercise FEV1. In addition, the 
statistical testing hierarchy has been changed to prioritise the maximal percentage FEV1
reduction (primary endpoint) and binary recovery endpoints following the 12 hour post-

dose exercise challenge.
Other minor corrections and edits have been made.

Amendment No. 3
This amendment has been written to adjust text to better reflect the intention of the 
protocol with regard to visit timing:
Visit 2 (currently Day 1) redefined as Day 0 and Visit 3 (currently Day 2) redefined as 
Day 1.
Visit window around day 29 removed and footnote added.
Text regarding timing of visits clarified to ensure that the intention of the protocol is 
clearly reflected
Other changes were made as follows:
Subject number will be assigned at Pre-Screening following informed consent rather than 
at Visit 1
Nucala™ added as an example prohibited medication
Rescue medication supply strategy has been removed and the reader referred to the SRM
Confirmation that post exercise vital signs will be immediately post exercise, not after 5 
minutes of rest.

PROTOCOL SYNOPSIS FOR STUDY 201832
Rationale
For many patients with symptomatic asthma, physical exertion is often a precipitating 
factor. Although varying in methodology and criteria, early studies showed that as many 
as 90% of asthmatic patients have bronchoconstriction after exercise. In subjects with 
symptoms of persistent asthma, exercise and other forms of physical activity represent 
only one of many triggers that lead to worsening symptoms. 
Chronic treatment with inhaled corticosteroids (ICS) has been shown to reduce the 
severity of asthma associated with exercise. However, some patients continue to 
demonstrate asthma symptoms and a decrease in lung function during exercise even 
while receiving ICS. In patients with persistent asthma, improvements in protection from 
exercise-induced bronchoconstriction (EIB) with ICS/long-acting beta2-agonist (LABA) 
combination product Fluticasone propionate (FP)/salmeterol (ADVAIRTM) have been 
demonstrated. However, differences between FP/salmeterol and FP monotherapy have 
not consistently been observed.  In a study that evaluated the effect of FP/salmeterol 
compared with FP over the 12 hour dosing interval, a large percentage of subjects in both 
the FP/salmeterol (18%) and FP (36% and 33% at Day 1 and Week 4, respectively) 
treatment arms failed to complete the second exercise challenge test 8.5 hours after 
dosing, suggesting loss of protection against EIB towards the end of the 12 hour dosing 
interval. 
FF/VI (Fluticasone furoate/Vilanterol), a new ICS/LABA combination treatment, is 
dosed once daily and has demonstrated significant bronchodilation over 24 hours. The 
purpose of this study is to determine if the once-daily administration of FF/VI 
demonstrates improved protection from EIB over ICS alone (FP) over the 24-hour dosing 
interval.
Objectives
Primary Objective
To evaluate the protective effect of fluticasone furoate/vilanterol (FF/VI) 100/25 mcg 
once-daily compared with fluticasone propionate (FP) 250 mcg twice-daily against 
exercise-induced bronchoconstriction in adolescent and adult subjects aged 12 to 50 with 
persistent asthma 
Primary Endpoint

Maximal percent decrease from pre-exercise FEV1 (Forced Expiratory Volume in 
One Second ) following exercise challenge at 12 hours post evening dose at the end

Equivalent of Tasks (METs), sleep duration)

Proportion of subjects with a 5 minute post-challenge FEV1 that was no more than 
5% lower than their pre-exercise FEV1 following the exercise challenge at 12 hours

Overall Design
This is a multicenter, randomized, double-blind, double-dummy, crossover study with 
two 2-week treatment periods separated by a 2-week wash-out period.  Subjects will 
participate in up to eight study visits (Visit 0 to Visit 7) over the course of the study and a 
follow up phone call approximately a week after Visit 7. Visits 1, 2, 3, 5 and 6 are 
evening visits that will be conducted between 5PM and 11PM. Visit 4 and Visit 7 are also 
evening visits that will begin between 5PM and 11PM and continue over a period of 
approximately 24 hours. Subjects will be required to attend three clinic visits during this 
24-hour period.
Standardized exercise challenge testing (using a treadmill) will be conducted at Visit 2 
for eligibility determination, Visit 3 and Visit 6 (after 23 hours of the first treatment dose 
in each Treatment Period); and at 12 and 23 hours post evening dose at Visits 4 and 7. 
Spirometry will be conducted at Screening (Visit 1), and pre-dose at Visit 5, and prior to 
each exercise challenge at Visits 2, 3, 4, 6 and 7. Serial spirometry (6 time points over 60 
minutes) as FEV1 only will be conducted after each exercise challenge test. At Visit 2, 
subjects must demonstrate a decrease in FEV1 of ≥20% when compared to the FEV1
obtained immediately pre-exercise for at least one of the post-exercise spirometry efforts 
obtained within 30 minutes post-challenge.  Subjects who achieve a decrease in FEV1 of 
15% to <20% may continue taking their daily run-in medication and repeat the eligibility 
exercise challenge and associated procedures once within a week of the original 
procedure. Subjects should be monitored until they reach a recovery level where their 
FEV1 value represents a 95% recovery of the pre-exercise FEV1 result.  Additional 
spirometry and rescue medication may be used as needed during recovery.
A Pre-Screening Visit (Visit 0) is included to obtain a signed Informed Consent, 
demography and to review concomitant medications, and may be conducted on the same 
day as Visit 1, if appropriate. 
At Visit 1, subjects meeting eligibility criteria and will enter a 4 week single-blinded run-
in period on fluticasone propionate (FP) 250 mcg twice daily (BD). Subjects with 
symptomatic allergic rhinitis at Visit 1 (screening) may be treated for up to four weeks 
with intranasal corticosteroids followed by a repeat screening visit to determine eligibility 
prior to entry into the study. Only one repeat screening visit will be performed following 
treatment with intranasal corticosteroids. Subjects that continue to be symptomatic after 
up to four weeks of treatment will be excluded. Eligible subjects will enter the run-in 
period. Subjects who are asymptomatic at screening, who become symptomatic during 
the study will remain in the study and may be treated with intranasal corticosteroids at a 
constant dose for the duration of the study.
Albuterol/salbutamol will be issued for rescue use during the run-in, wash-out and 
treatment periods as needed.  Subjects will be instructed to contact the site if they develop 
worsening asthma.  
All subjects will be given a paper diary during the run-in, washout and treatment periods 
to record any medical problems experienced during the study, any medications taken, and 
rescue medication usage.

A screening electrocardiogram (ECG) and a complete physical examination will be 
conducted at Visit 1. Vital signs including pulse rate and systolic and diastolic blood 
pressure will be obtained at each clinic visit, including any Early Withdrawal visit. At all 
time points where both vital signs and spirometry are performed, vital signs will be done 
before the spriometry measurement. At visits where the exercise challenge is performed, 
vitals will be measured before (prior to the pre-exercise spirometry) and after the exercise 
challenge. 
Asthma control will be assessed using the ACQ-5 at Visits 2, 4, 5 and 7.
Physical activity levels will be monitored to assess activity outside the clinic with the use 
of a physical activity monitor (SenseWear Armband accelerometer) worn for 7 days prior 
to Visit 2 (baseline), for 7 days prior to Visit 4 (during the last week of Treatment Period 
1), for 7 days prior to Visit 5, and for 7 days prior to Visit 7 (during the last week of 
Treatment Period 2).  Subjects unwilling or unable to participate in daily physical activity 
monitoring may still participate in the study, if appropriate.
A follow up phone call will be conducted approximately 7 days after Visit 7.
Treatment Arms and Duration
Two treatment arms will be employed for the study: 

FF/VI 100/25 mcg QD via ELLIPTA + Placebo BD via Diskus

FP 250 mcg BD via Diskus + Placebo QD via ELLIPTA
As this is a 2-period cross-over study, all randomized subjects will receive both 
treatments in the study, either in Treatment Period 1 or Treatment Period 2. Also, each 
subject will receive a Diskus and ELLIPTA inhaler in Treatment Period 1 and Treatment 
Period 2.
Subjects will complete a 4-week single blind run-in on FP 250 mcg BID, followed by 2-
week double-blind Treatment Period 1 on randomized treatment, a 2-week single blind 
washout period on FP 250 mcg BID, 2-week double-blind Treatment Period 2 receiving 
the alternative treatment, and follow-up contact approximately 7-days after completing 
Treatment Period 2. The total duration of study participation is approximately 11 weeks; 
and up to 15 weeks for subjects with SAR at screening who may need to be treated with 
intranasal corticosteroids followed by a repeat screening visit.
Type and Number of Subjects
Approximately 275 subjects with persistent asthma with evidence of EIB and current use 
of a low- to moderate-dose inhaled corticosteroid (ICS) will be screened in order to 
randomize 66 subjects, assuming a 20% screen failure rate and 70% run-in failure rate. 
This is to achieve 56 evaluable subjects completing the exercise challenges and the FEV1
evaluations at the end of both treatment periods. This calculation assumes a 15% 
withdrawal rate during the study.

Analysis
The primary treatment comparison will be between the FF/VI combination and FP and 
will be performed using the intent-to-treat (ITT) Population. Demonstration of efficacy 
for the treatments will be based on a hypothesis testing approach whereby the null 
hypothesis is that there is no difference between the population treatment groups and the 
alternative hypothesis is that there is a difference between the population treatment 
groups.  
The primary endpoint will be defined as the maximal percent decrease from pre-exercise 
FEV1 at 12 hours post-evening dose at the end of the 2-week treatment period. Pre-
exercise FEV1 will be defined as the FEV1 value collected prior to the exercise challenge 
test at 12 hours post-dose. Maximal percent decrease will be defined as the percent 
change from the pre-exercise FEV1 value to the minimum FEV1 collected within one 
hour following exercise challenge at 12 hours post-dose. Mean post-exercise minimum 
FEV1 measurements and mean maximal percent decrease from pre-exercise values will 
be summarized with descriptive statistics by treatment group. A linear mixed model will 
be fitted that includes the following covariates: treatment, subject-level mean of the FEV1 
period baselines (mean of the 2 period baselines per subject), centered period-level 
baseline FEV1 (period baselines centered using subject-level mean of the FEV1 period 
baselines), gender, age and treatment period as fixed effects, and a random intercept for 
each subject.
A 2-sided 5% probability associated with incorrectly rejecting the null hypothesis 
(significance level) is considered acceptable for this study.  In order to account for 
multiplicity, the primary hypothesis test on the primary endpoint for the ITT population 
will act as a gatekeeper for all other hypothesis tests using the secondary endpoints, 
where these tests will proceed in a pre-defined order. If a given statistical test fails to 
reject the null hypothesis of no population treatment group difference at the significance 
level of 0.05, then all tests lower down the hierarchy will be interpreted as descriptive 
only.

INTRODUCTION
2.1.
Background
For many patients with symptomatic asthma, physical exertion is often a precipitating 
factor. Although varying in methodology and criteria, early studies showed that as many 
as 90% of asthmatic patients have bronchoconstriction after exercise [McFadden, 1994; 
Poppius, 1970]. In subjects with symptoms of persistent asthma, exercise and other forms 
of physical activity represent only one of many triggers that lead to worsening symptoms. 
Chronic treatment with inhaled corticosteroids (ICS) has been shown to reduce the 
severity of asthma associated with exercise. However, some patients continue to 
demonstrate asthma symptoms and a decrease in lung function during exercise even 
while receiving ICS. The addition of a long-acting beta2-agonist (LABA) to ICS has been 
considered as a possible treatment in these cases. International guidelines such as those 
issued by the Global Initiative for Asthma (GINA) [GINA, 2015] and the National Heart 
Lung and Blood Institute (NHLBI) [NIH, 2007] advocate the use of inhaled LABA in 
combination with ICS as maintenance therapy in asthma for subjects who remain 
symptomatic on low- to mid-dose ICS. 
2.2.
Study Rationale
In patients with persistent asthma, improvements in protection from exercise-induced 
bronchoconstriction (EIB) with ICS/LABA combination product Fluticasone propionate
(FP)/salmeterol (Advair™) have been demonstrated [Murray, 2011; Pearlman, 2009; 
Weiler, 2005]. However, differences between FP/salmeterol and FP monotherapy have 
not consistently been observed [Murray, 2011; Weiler, 2005]. In a study that evaluated 
the effect of FP/salmeterol compared to FP over the 12 hour dosing interval [Weiler, 
2005], a large percentage of subjects in both the FP/salmeterol (18%) and FP (36% and 
33% at Day 1 and Week 4, respectively) treatment arms failed to complete the second 
exercise challenge test 8.5 hours after dosing, suggesting loss of protection against EIB 
towards the end of the 12 hour dosing interval. 
FF/VI, a new ICS/LABA combination treatment, is administered once daily and has 
demonstrated significant bronchodilation over 24 hours. The purpose of this study is to 
determine if the once-daily administration of FF/VI demonstrates improved protection 
from EIB over ICS alone (FP) over the entire 24-hour dosing interval.
2.3.
Brief Background
Fluticasone furoate (FF) is a novel glucocorticoid approved in the US for use as a once-
daily inhaled treatment for asthma.  
Vilanterol (VI) is an orally inhaled LABA. The inhaled fixed-dose combination of once-
daily VI and FF is approved in the US for the maintenance treatment of asthma in adults 
aged 18 and older, and in the European Union and other regions in adults and adolescents 
≥12 years of age. The FF/VI 100/25 mcg combination is being developed globally as a

once-daily therapy for the long-term maintenance treatment of asthma in adults and 
children ≥5 years of age. The inhaled fixed-dose combination of FF and VI is 
administered via the ElliptaDry Powder Inhaler (DPI).  
Information on the physical, chemical, and pharmaceutical properties of FF alone, VI 
(GW642444) alone, and FF/VI in combination may be found in the respective 
Investigator Brochures (IB).

STUDY DESIGN
5.1.
Overall Design
This is a multicenter, randomized, double-blind, double-dummy, crossover study with 
two 2-week treatment periods separated by a 2-week wash-out period. Subjects will 
participate in up to eight study visits (Visit 0 to Visit 7) over the course of the study and a 
follow up phone call approximately a week after Visit 7. Visits 1, 2, 3, 5 and 6 are 
evening visits that will be conducted between 5PM and 11PM. Visit 4 and Visit 7 are also 
evening visits that will begin between 5PM and 11PM and continue over a period of 
approximately 24 hours. Subjects will be required to attend three clinic visits during this 
24-hour period.
Standardized exercise challenge testing (using a treadmill) will be conducted at Visit 2 
for eligibility determination, Visit 3 and Visit 6 (after 23 hours of the first dose in each 
Treatment Period); and at 12 and 23 hours post evening dose at Visits 4 and 7. 
Spirometry will be conducted at Screening (Visit 1), and pre-dose at Visit 5 and prior to 
each exercise challenge at Visits 2, 3, 4, 6 and 7. Serial spirometry (6 time points over 60 
minutes) as FEV1 only will be conducted after each exercise challenge test. At Visit 2, 
subjects must demonstrate a decrease in FEV1 of ≥20% when compared to the FEV1
obtained immediately pre-exercise for at least one of the post-exercise spirometry efforts 
obtained within 30 minutes post-challenge.  Subjects who achieve a decrease in FEV1 of 
15% to <20% may continue taking their daily run-in medication and repeat the eligibility

exercise challenge and associated procedures once within a week of the original 
procedure. Subjects should be monitored until they reach a recovery level where their 
FEV1 value represents a 95% recovery of the pre-exercise FEV1 result.  Additional 
spirometry and rescue medication may be used as needed during recovery. 
A Pre-Screening Visit (Visit 0) is included to obtain a signed Informed Consent (ICF), 
demography and to review concomitant medications, and may be conducted on the same 
day as Visit 1, if appropriate. 
At Visit 1, subjects meeting eligibility criteria will enter a 4-week single-blinded run-in 
period on fluticasone propionate (FP) 250 mcg twice daily (BD). Subjects with 
symptomatic allergic rhinitis at Visit 1 (screening) may be treated for up to four weeks 
with intranasal corticosteroids followed by a repeat screening visit to determine eligibility 
prior to entry into the study. Only one repeat screening visit will be performed following 
treatment with intranasal corticosteroids. Subjects that continue to be symptomatic after 
up to four weeks of treatment will be excluded. Eligible subjects will enter the run-in 
period. Subjects who are asymptomatic at screening, who become symptomatic during 
the study will remain in the study and may be treated with intranasal corticosteroids at a 
constant dose for the duration of the study.
Albuterol/salbutamol will be issued for rescue use during the run-in, wash-out and 
treatment periods as needed.  Subjects will be instructed to contact the site if they develop 
worsening asthma.  
All subjects will be given a paper diary during the run-in, washout and treatment periods 
to record any medical problems experienced during the study, any medications taken, and 
rescue medication usage.

A screening electrocardiogram (ECG) and a complete physical examination will be 
conducted at Visit 1. Vital signs including pulse rate and systolic and diastolic blood 
pressure will be obtained at each clinic visit, including any Early Withdrawal visit. At all 
time points where both vital signs and spirometry are performed, vital signs will be done 
before the spirometry measurement. At visits where the exercise challenge is performed, 
vitals will be measured before (prior to the pre-exercise spirometry) and after the exercise 
challenge. 
Asthma control will be assessed using the ACQ-5 at Visits 2, 4, 5 and 7.
Physical activity levels will be monitored to assess activity outside the clinic [Mitchell, 
2014] using a physical activity monitor (SenseWear Armband accelerometer) worn for 7 
days prior to Visit 2 (baseline), for 7 days prior to Visit 4 (during the last week of 
Treatment Period 1), for 7 days prior to Visit 5, and for 7 days prior to Visit 7 (during the 
last week of Treatment Period 2). Subjects unwilling or unable to participate in daily 
physical activity monitoring may still participate in the study, if appropriate. See Study 
Reference Manual (SRM) for additional details.
A follow up phone call will be conducted approximately 7 days after Visit 7.
Re-screening of subjects is not allowed in this study with the exception of subjects with 
symptomatic allergic rhinitis at screening who may have a repeat screening visit after 
treatment with intranasal corticosteroids.
There are no plans to routinely provide any of the study treatments for compassionate use 
following study completion, as asthma treatments including ICS/LABA combination 
products are available worldwide.
Supplementary study conduct information not mandated to be present in this protocol is 
provided in the SRM. The SRM will provide the site personnel with administrative and 
detailed technical information that does not impact subject safety.
5.2.
Treatment Arms and Duration
Two treatment arms will be employed for the study: 

FF/VI 100/25 mcg QD via ELLIPTA + Placebo BD via Diskus

FP 250 mcg BD via Diskus + Placebo QD via ELLIPTA
As this is a 2-period cross-over study, all randomized subjects will receive both 
treatments in the study either in Treatment Period 1 or Treatment Period 2. Also, each 
subject will receive a Diskus and ELLIPTA inhaler in Treatment Period 1 and Treatment 
Period 2.
Subjects will complete a 4-week single blind run-in on FP 250 mcg twice daily, followed 
by 2-week double-blind Treatment Period 1 on randomized treatment, a 2-week single 
blind washout period on FP 250 mcg twice daily, 2-week double-blind Treatment Period 
2 receiving the alternative treatment, and follow-up contact approximately 7-days after 
completing Treatment Period 2. The total duration of study participation is approximately

21
11 weeks; and up to 15 weeks for subjects with SAR at screening who may need to be 
treated with intranasal corticosteroids followed by repeat screening visit.
5.3.
Type and Number of Subjects
Subjects must have been diagnosed with persistent asthma with evidence of EIB and have 
been using a low- to moderate-dose ICS as a part of their asthma maintenance treatment.
Assuming a 20% screen failure rate and 70% run-in failure rate, approximately 275 
subjects will be screened in order to randomize 66 subjects in this study and ultimately 
achieve 56 evaluable subjects who have completed both the exercise challenges and 
spirometric evaluations at the end of both treatment periods. This calculation assumes a 
15% withdrawal rate during the study.  
5.4.
Design Justification
The study design is based on the practice parameters for assessing EIB developed by the 
Joint Task Force on Practice Parameters for Allergy and Immunology [Weiler, 2010], 
American Thoracic society clinical practice guideline [Parsons, 2013], EMA (European 
Medicines Agency) Note on Guidance on Clinical Investigation of Medicinal Products 
for Treatment of Asthma [EMA, 2013] and FDA Draft Guidance for the Development of 
Drugs for Exercise-Induced Bronchospasm [FDA Guidance for Industry, 2002].  
A randomized, double-blind, double dummy, cross-over design is a well-validated means 
to assess the efficacy and safety of two treatment groups. A cross-over design was chosen 
to reduce the impact of confounding variables, and allow for between and within group 
comparisons. The expectation that mild to moderate patients with EIB would already be 
using an ICS necessitated standardization of baseline ICS therapy and eliminates the need 
for use of a placebo comparator.  Considering a 4-week run-in period on FP, two weeks 
of treatment with FF/VI followed by exercise challenge is considered adequate to observe 
a treatment effect for this within-subject comparison. A two-week washout period is 
adequate to wash out the LABA, VI, prior to Treatment Period 2.
FP was chosen as the “gold standard” ICS active comparator as its ability to prevent EIB 
has been previously characterized and FF is not currently commercially available outside 
of the US.
The primary endpoint of maximal percent decrease from pre-exercise baseline FEV1 is a 
well-established measure of EIB and is consistent with agency guidance and established 
practice parameters. Exercise challenge testing at 12, and 23 hours post-dose at the end of 
each Treatment Period will allow for assessment of the duration of protective effect for 
the interventions.
5.5.
Dose Justification
The inhaled FF/VI 100/25 mcg dose combination corresponds to the dose approved in the 
US (adults) and EU (adults and adolescents) for the treatment of asthma corresponding to 
low to moderate ICS/LABA asthma therapy. FF100 is deemed a low/mid strength ICS.

Risk Assessment
For FF/VI the following risks and the mitigation strategy as applicable to asthma patients were taken from the summary of safety concerns 
in the European Union – Risk Management Plan (EU-RMP). For FF/VI the data/rationale for the risk were derived from the 2014 
Investigator’s Brochure, from an integrated analysis of key RELVAR studies (Integrated Summary of Safety for Fluticasone 
Furoate/Vilanterol v02 DBL 31 Jan 2014), from the RMP version 6.2 and in the RELVAR/BREO ELLIPTA Prescribing Information for 
countries in which FF/VI is approved for marketing.
Potential Risk of Clinical Significance
Summary of Data/Rationale for Risk
Mitigation Strategy
Investigational Product (IP) [FF/VI] 
Pneumonia in patients with asthma
The incidence of pneumonia in patients with 
asthma was uncommon. The incidence (adjusted 
for exposure) seen with FF/VI 100/25 microgram 
strength (8.5/1000 patient years) was similar to 
placebo (9.3/1000 patient years). No risk factors 
were identified.
In an analysis performed on the 18 key studies in 
subjects with asthma pneumonia  was reported 
by 0.5% (13 of 2369) of subjects who received 
FF/VI 100/25 subjects and 0.2% (2 of 1070) of 
subjects who received placebo.a
The risk of pneumonia in asthma patients is very 
low and is consistent with the risk of other ICS.  
Subjects are not at an increased risk in this 
study, since they enter the study stable on an 
existing ICS treatment. Subjects are alerted to 
the potential risk of pneumonia in the informed 
consent. Investigators are informed of the risk in 
Section 1.2.3 (Asthma Clinical Studies) and 
Section 5.3.3 (Safety in Asthma Clinical Studies) 
of the IB. Subjects with concurrent respiratory 
disease are excluded from the study.
Asthma related intubations and deaths
This is a class effect of LABA in asthma. This 
has not been observed for FF/VI.

composite endpoint of asthma-related deaths, 
intubations, and hospitalizations (asthma

significant difference among age groups.  The 
composite event incidence difference for all ages 
was 6.3 events per 1000 patient-years (95% 
confidence interval [CI]: 2.2-10.3) with LABAs 
compared with no LABA use. Among the 15,192 
patients with concurrent ICS use, the incidence 
difference was 0.4 events per 1000 patient-years 
(95% CI: -3.8 to 4.6).  The authors noted a trend 
of greater excess risk with LABA among the 
younger age groups [McMahon, 2011].
Serious cardiovascular events
In an analysis performed on the 18 key studies in 
subjects with asthma, eight serious 
cardiovascular events have been reported in 
patients exposed to FF/VI. Seven events in FF/VI 
100/25 and one event in FF/VI 200/25. This 
represents an incidence less than 1% in the 
asthmatic patients exposed to FF/VI.a
The events reported include atrial fibrillation, 
acute coronary syndrome, coronary artery 
disease, hypertension, myocardial ischemia, 
tachyarrhythmia and tachycardia.
Subjects with existing serious cardiovascular 
disease and/or abnormal ECG findings are 
excluded from the study. Investigators are made 
aware of the potential class effects of LABAs and 
are advised to exercise caution for subjects with 
existing serious cardiovascular disease (Section 
6.3 [Warnings and Precautions] of the IB).
Hypersensitivity
No FF/VI drug related hypersensitivity was noted 
in clinical trials.
Spontaneous reports of hypersensitivity 
reactions have been reported in post-marketing 
Subjects will be informed about the risk of 
hypersensitivity in the informed consent.

in Section 6.2 (Contraindications) of the IB.
Decreased bone mineral density and associated 
fractures
Risk of fracture has been associated with oral 
corticosteroids. It is unclear if inhaled 
corticosteroids carry the same risk. 
There were few events associated with bone 
disorders or fractures reported during the asthma 
development program. These events tended to 
be those associated with trauma. 
Currently the risk of reduced bone mineral 
density has not been observed in the asthma 
population [Jones, 2002]. In addition specific 
assessments in adolescents with asthma have 
not demonstrated an effect on bone mineral 
density, when controlled for growth [König, 1993; 
Turpeinen, 2010].
In an analysis performed on the 18 key studies in 
subjects with asthma bone fractures were 
reported by <1% (16 of 2369) of subjects who 
received FF/VI 100/25.a
Subjects will be informed about the risk of 
decreased bone mineral density and bone 
fractures in the informed consent. Investigators 
are made aware of the potential for this ICS 
class effect. Subjects will be advised to seek 
medical treatment if any signs of decreased bone 
mineral density or fractures occur.

Potential Risk of Clinical Significance
Summary of Data/Rationale for Risk
Mitigation Strategy
Adrenal Suppression
This is considered a class effect of ICS. 
Preclinical studies showed that FF effects are 
comparable with other corticosteroids. No 
studies have shown a clinically relevant effect of 
FF/VI on the hypothalamic-pituitaryadrenal axis 
(HPA) at the 100/25 strength. This includes a 
formal HPA study (HZA106851), using 24-hour 
serum cortisol measurements, and multiple 
studies with chronic obstructive pulmonary 
disorder (COPD) and asthma subjects which 
monitored urinary cortisol.
Subjects will be informed about the risk of 
adrenal suppression in the informed consent. 
Investigators are made aware of the potential for 
this class effect in Section 6.3 (Warnings and 
Precautions) of the IB. If systematic symptoms
appear, investigators should implement an 
appropriate treatment while observing the 
subject’s’ asthma symptoms.
Corticosteroid associated eye disorders
This is considered a class effect of ICS. 
Preclinical studies showed FF at high dose 
comparable to other high dose corticosteroids. In 
study HZA106839 (FF/VI, FF and FP in subjects 
with asthma), formal ophthalmic assessments 
were conducted (including LOCS III evaluations 
for ocular opacities) throughout the study. This 
study showed no apparent effects on lens 
opacification, compared to baseline. During 
studies in both subjects with asthma and COPD, 
no associated affect on ocular disorders was 
observed.
Subjects will be informed about the risk of
corticosteroid associated eye disorders in the 
informed consent. Subjects will be advised to 
seek medical treatment if any signs of eye 
disorder occur. Investigators are made aware of 
the potential for this class effect in Section 
5.3.3.7 (Ophthalmic Effects) of the IB.

study reference manual [SRM].) 
If a subject's FEV1 decreases to ≥40% from 
their pre-exercise FEV1 following exercise 
challenge, he/she must receive rescue therapy. If 
he/she requires rescue therapy with anything 
other than MDI (Metered Dose Inhaler )or 
nebulized albuterol/salbutamol or ipratropium 
(secondarily) following the exercise challenge 
assessment, he/she will not be allowed to 
continue in the study. 
Subjects will be monitored until their FEV1 
reaches ≥95% of their pre-exercise FEV1. 
Rescue Albuterol/salbutamol may be given 
during recovery.
Cardiovascular stress resulting from exercise
Rigorous exercise can lead to heart attack, 
stroke and even death. 
Subjects with existing serious cardiovascular 
disease and abnormal ECG findings are 
excluded from the study. Investigators are made 
aware of the potential class effects of LABAs and 
are advised to exercise caution for subjects with 
existing serious cardiovascular disease (Section 
6.3 [Warnings and Precautions] of the IB).
Musculoskelatal injury resulting from exercise 
challenge testing
Musculoskelatal injury is a risk of exercise on a 
treadmill.
The exercise challenge will begin gradually to 
allow the subject to warm up over 2 minutes, and 
end with a gradual stop.

Unknown risks to an embryo, fetus (unborn 
baby) or nursing infant
There are no studies with FF/VI or the individual 
components (FF and VI) in pregnant women.
As specified in the protocol:
Women who are pregnant, lactating or are 
planning on becoming pregnant during the 
study are not eligible to participate in this 
study.
Female subjects must be postmenopausal or 
using a highly effective method for avoidance 
of pregnancy while in this study.
If a female subject becomes pregnant during 
the study, she should let the study doctor 
know immediately. The study medication will 
be stopped.
For women of child-bearing potential, a urine 
pregnancy test will be performed at Screening

Asthma symptoms may worsen during the study
As specified in the protocol:
The use of certain asthma medications is 
excluded prior to and during the study.
After Visit 1, the use of rescue medication 
(albuterol/salbutamol) must be withheld for at 
least 6 hours prior to and during each clinic 
visit.
Patients will be placed on an ICS alone 
treatment during the run-in period and 
possibly during the treatment period.
The informed consent advises the subject to:
Talk to the study doctor about the excluded 
medications before deciding and consenting 
to participate in the study.
Use the rescue medication 
(albuterol/salbutamol) if asthma symptoms 
worsen.
Notify the study doctor or staff if his/her 
asthma symptoms worsen or do not get better 
after using the rescue medication.
Go immediately to the emergency 
department/seek medical attention if the 
symptoms are severe.
Shortness of breath, coughing, lightheadedness 
or fainting, and/or chest tightness during the 
spirometry measurements
None.
As specified in the informed consent form for this 
study, if any of these symptoms should happen 
to the subject, he/she will receive medical 
treatment.

Risk assessment for FP 250mcg
FLOVENT/FLIXOTIDE is a marketed drug that contains the ICS fluticasone propionate
(FP 250 mcg). A similar profile of undesirable effects as reported for ICS may occur with 
FP. Since FLOVENT/FLIXOTIDE contains an ICS (FP), the risk mitigation strategies 
for FF (ICS) as mentioned in Section 5.6.1 will be applicable.
Please refer to the authorized product label for further information about the risks of 
using FP. In this study, FP will be used in line with the recommendations provided in the 
product label.
5.6.3.
Benefit Assessment
Combined treatment with ICS and LABA has been shown to be more effective than the 
individual components in asthma, leading to the development of fixed dose combination 
inhalers. The use of ICS/LABA combinations is now well established in international 
treatment guidelines for moderate to severe persistent asthma patients for whom 
treatment with ICS alone is not sufficient. 
In patients with persistent asthma, improvements in protection from EIB with ICS/LABA 
combination product FP/salmeterol (Advair) have been demonstrated [Murray, 2011; 
Pearlman, 2009; Weiler, 2005].  Once-daily FF/VI 100/25 mcg is hypothesized to 
provide protection from EIB throughout the dosing period.
FP 250 mcg is a commercially available product for the treatment of persistent asthma 
and has a recognized safety profile. 
5.6.4.
Overall Benefit: Risk Conclusion
GlaxoSmithKline (GSK) has assessed this study for any potential risks that a subject may 
experience. The investigational product (IP) FF/VI has an acceptable safety profile for 
clinical use and there are no significant associated risks. This conclusion is supported by 
the results of previously performed clinical studies with the products in healthy 
volunteers and subjects with Asthma and COPD. The ICS (FP) described above will be 
used at a dose and frequency that is approved for the treatment of Asthma and has an 
acceptable safety profile for use. This conclusion is supported by the results of previously 
performed clinical studies and post-marketing experience (see local label).
Adverse effects that could be associated with the use of FF/VI and FP will be closely 
monitored. A safety criterion outlining details for subject withdrawal is included in the 
protocol (Section 6.4, Withdrawal Criteria). A thorough summary and evaluation of the 
available pre-clinical data can be found in the IB. Routine safety analysis of this study 
will be conducted by the company.
Taking into account the measures taken to minimize risk to subjects participating in this 
study, the potential risks identified in association with FF/VI and FP are justified by the 
anticipated benefits that may be afforded to patients with asthma.

6.3.
Screening/Baseline/Run-in Failures
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 reason details, Eligibility Criteria, and 
any Serious Adverse Events.
A subject who is assigned a subject number, has signed the informed consent, and has 
completed at least one study procedure, but does not enter the run-in period of the study 
is considered a ‘screen failure’.  
A subject who completes the screening visit and is dispensed FP 250 mcg, 
albuterol/salbutamol for rescue use, and a medical conditions diary card is considered to 
have entered the run-in period.  A subject who has entered the run-in period, but is not 
randomized to study treatment medication, is classified as a ‘run-in failure’.  
At a minimum, the following information will be collected for subjects who fail 
screening or run-in:
1.
Demographic information for race, age and gender
2.
Reason for screen/run-in failure (screen/run-in failure eCRF page, 
inclusion/exclusion criteria eCRF page, and randomization criteria eCRF page 
[if applicable])

6.4.
Withdrawal/Stopping Criteria
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. Once withdrawn from the investigational product a subject will be 
considered withdrawn from the study. Subjects who are withdrawn from the study may 
be replaced at the discretion of the Sponsor.  The primary reason for withdrawal will be 
recorded in the eCRF.
6.4.1.
Study Specific Withdrawal Criteria
A Subject will be withdrawn from the study if any of the following withdrawal criteria 
are met:
1.
Liver Chemistry: Meets any of the protocol-defined liver chemistry stopping 
criteria (see Appendix 2).
Liver chemistry stopping and increased monitoring criteria have been 
designed to assure subject safety and evaluate liver event etiology (in alignment 
with the FDA premarketing clinical liver safety guidance). 
http://www.fda.gov/downloads/Drugs/GuidanceComplianceRegulatoryInformatio
n/Guidances/UCM174090.pdf
If the liver chemistry stopping criteria are met by any subject participating in this 
study, treatment restart or rechallenge is not permitted.
2.
Severe Asthma Exacerbation
Subjects who experience a severe asthma exacerbation at any time during the study must 
be withdrawn from the study.  A severe exacerbation is 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 during the study. 
3.
Worsening of Asthma requiring additional treatment
Subjects requiring rescue therapy with anything other than MDI or nebulized 
albuterol/salbutamol or ipratropium (secondarily) following the exercise challenge 
assessment should be withdrawn.
NOTE: If a subject's FEV1 decreases to ≥40% from their pre-exercise FEV1
following exercise challenge, he/she must receive rescue therapy. If he/she 
requires rescue therapy with anything other than MDI or nebulized 

2015N231308_03
CONFIDENTIAL
201832
37
albuterol/salbutamol or ipratropium (secondarily) following the exercise 
challenge assessment, he/she is not allowed to continue in the study
Subjects who experience asthma worsening outside of the exercise challenges 
which, in the opinion of the investigator, requires additional asthma treatment 
other than study medication or study supplied albuterol/salbutamol should be 
withdrawn. 
4.
Pregnancy: Positive urine pregnancy test
5.
ECG: Discontinuation is required if any of the following ECG criteria are met 
during the study:
QTcF>500 msec or uncorrected QT>600 msec 
Change from baseline: QTcF> 60msec
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 subject to 
determine eligibility for and discontinuation from the study.  This formula 
may not be changed or substituted once the subject has been enrolled.
For example, if a subject is eligible for the protocol based on QTcB, then 
QTcB must be used for discontinuation of this individual subject as well.
Once the QT correction formula has been chosen for a subject’s eligibility, 
the same formula must continue to be used for that subject for all QTc data 
being collected for data analysis.  Safety ECGs and other non-protocol 
specified ECGs are an exception.  
The QTc should be based on single or averaged QTc values of triplicate 
electrocardiograms obtained over a brief (e.g., 5-10 minute) recording period.  
Details on performing ECG assessments can be found in Section 8.4.6.
6.4.2.
Reasons for Study Withdrawal
The primary reason for Study Withdrawal will be recorded in the eCRF and any data 
collected up until the point of withdrawal will be used in the data analyses.

Lost to Follow up (Non-Attendance)
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”. 
6.4.4.
Early Withdrawal Visit
Subjects may withdraw or be withdrawn from the study for any reason. If withdrawal 
occurs, the investigator must make every effort to have the subject return to the clinic as 
soon as possible after the subject stopped study medication for an Early Withdrawal 
(EW) Visit (ideally within 24 hours).  At withdrawal, all study medications and other 

2015N231308_03
CONFIDENTIAL
201832
39
study-related materials should be returned to the site by the subject (Time and Events 
Table Table 3).  In the event a subject withdraws at, or during, a scheduled visit, an Early 
Withdrawal Visit is not required.  However, all study procedures scheduled at an Early
Withdrawal Visit must be performed at this visit instead.  A follow-up phone contact 
should be made 7 days (± 2 days) after the Early Withdrawal Visit.
Following completion of these procedures, the subject will be discharged from the study.  
Upon completion of the Early Withdrawal Visit, each subject may resume any asthma 
medications deemed appropriate by the investigator for the management of the subject.
In the event that a subject is withdrawn from the study due to an adverse event, the 
investigator must attempt to follow the subject until the adverse event has either resolved 
or has become clinically insignificant.
6.5.
Subject and Study Completion
A completed subject is one who has completed all phases of the study including the 
follow-up phone contact. 
The end of the study is defined as the last subject’s last contact.
7.
STUDY TREATMENT
7.1.
Investigational Product and Other Study Treatment
The term ‘study treatment’ is used throughout the protocol to describe any combination 
of products received by the subject as per the protocol design. Study treatment may 
therefore refer to the individual study treatments or the combination of those study 
treatments.
Albuterol/salbutamol will be given to all subjects to use throughout the study to treat 
acute asthma symptoms as needed per product label. Only study-supplied 
albuterol/salbutamol should be used for rescue during the study. Rescue usage will be 
recorded once daily in the subject’s paper diary. Do not record albuterol/salbutamol 
use in the eCRF.
Albuterol/salbutamol inhalation aerosol will be supplied as detailed in the SRM.

Assignment of Subject Number
At the Pre-screen Visit, a unique Subject Number (CRF number) will be assigned to any 
subject who has given informed consent. The unique Subject Number will be used to 
identify individual subjects during the course of the study. 
All subjects that have a repeat screening visit following treatment for symptomatic 
allergic rhinitis will continue to use the same subject number assigned at the original 
screening visit.
7.2.2.
Assignment of Treatment Number
Subjects meeting the randomization eligibility criteria at Visit 2 will be randomized to a 
treatment group through an Interactive Response Technology (IRT). The IRT will 
confirm the subject’s CRF number (Subject Number) and provide two additional 
numbers:

A randomization number will be assigned from a randomization schedule 
generated by Clinical Statistics, prior to the start of the study, using validated 
internal software. Once assigned, this number must not be reassigned to any 
other subject in the study.

Two treatment pack numbers will be provided that identifies the single blinded 
study medication (Diskus) and double-blind study medication (ELLIPTA and 
Diskus) that should be dispensed to the subject from the investigator’s inventory

7.3.
Blinding
Subjects will be single blinded to the study medication given in the run-in and washout 
periods. Investigators and site staff will be unblinded to the run-in and washout 
medication. 
The treatment periods will be double-blind, double-dummy 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 eCRF 

GSK’s Global Clinical Safety and Pharmacovigilance (GCSP) staff may unblind 
the treatment assignment for any subject with a Serious Adverse Event (SAE). If 
the SAE requires that an expedited regulatory report be sent to one or more 
regulatory agencies, a copy of the report, identifying the subject’s treatment 
assignment, may be sent to investigators in accordance with local regulations 
and/or GSK policy.
7.4.
Packaging and Labeling
The contents of the label will be in accordance with all applicable regulatory 
requirements.
7.5.
Preparation/Handling/Storage/Accountability
No special preparation of study treatment is required. Eligible subjects will be taught 
proper use of the Diskus inhaler and administer their first dose of inhaled FP 250 mcg at 
Visit 1. Randomized subjects will be taught proper use of the ELLIPTA inhaler at Visit 2 
and administer their first doses from each inhaler (active and placebo) at the visit. 

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.
7.6.
Investigational Product Malfunction
Any investigational product inhaler that fails to function properly must be identified to 
GSK personnel for return to GSK for testing. Details of the failure will be documented in 
the eCRF. The subject should return the inhaler to the clinic as soon as possible to avoid 
missing any doses. The site will then contact GSK’s internal IVRS (also known as the 
Registration and Medication Ordering System [RAMOS] NG) and obtain a new 
treatment pack number for this subject and dispense a new study medication kit from the 
site's investigational product supply, as instructed per the IVRS. 
7.7.
Compliance with Study Treatment Administration
Subject compliance with study medication will be assessed at all visits (including at Early 
Withdrawal) via review of the dose counters on the ELLIPTA and DISKUS inhalers. 
This information will be recorded in the eCRF. Subjects who are not compliant with run-
in medication administration or study drug administration should be counselled on 
appropriate dosing of study drug and this counselling should be noted in the source 
documentation. Subjects who demonstrate <80% compliance may be withdrawn from the 
study upon consultation with the Sponsor. 
7.8.
Treatment of Study Treatment Overdose
For this study, an overdose will be defined as the subject receiving any amount of 
investigational product greater than the maximum dose permitted by the protocol, which 
results in clinical signs or symptoms.
GSK does not recommend specific treatment for an overdose. 

2015N231308_03
CONFIDENTIAL
201832
44
In the event of an overdose the investigator [or treating physician] should use their 
discretion as to whether other treatment is warranted and contact the Medical Monitor. 
Decisions regarding dose interruptions or modifications will be made by the investigator 
in consultation with the Medical Monitor based on the clinical evaluation of the subject.
7.9.
Treatment after the End of the Study
Subjects will not receive any additional treatment from GSK after completion of the 
study as other treatment options are available for persistent asthma. 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. At the end of Visit 7, investigators should prescribe asthma medication 
appropriate to the severity of the subject’s asthma in accordance with asthma guidelines 
[GINA, 2015; NIH, 2007]. Do not record asthma medications started on or after the 
final clinic visit in the eCRF.
7.10.
Concomitant Medications and Non-Drug Therapies
The names, doses, and regimens of the asthma medications taken during the 12 weeks 
prior to Visit 1 must be recorded in the Concomitant Medications section in the eCRF.
All concomitant medications taken during the study will be recorded in the eCRF. The 
minimum requirement is for the reporting of the drug name and dates of administration. 
Study provided albuterol/salbutamol should NOT be recorded in the eCRF.
Asthma medications taken after the final clinic visit will not be recorded in the eCRF.

8.3.1.
Spirometry
Subjects should abstain from drinking beverages with high caffeine content such as tea or 
coffee for 4 hours prior to the spirometry procedure. 
FEV1 should be measured using spirometry equipment that meets or exceeds the minimal 
recommendations of the American Thoracic Society (ATS)/European Respiratory Society 
(ERS) [Miller, 2005]. All sites will use standardized spirometry equipment provided by 
an external vendor. Full FEV1 and FVC will be conducted at Visit 1, and pre-dose at Visit 
5, and prior to each exercise challenge at Visits 2, 3, 4, 6 and 7. 
For full FEV1 and FVC testing at Screening and at randomisation (Visit 2), at least two 
valid and two repeatable (with no more than 8) efforts should be obtained using 
ATS/ERS guidelines. For all other visits where full FEV1 and FVC testing is performed 
(prior to each exercise test at visits 3, 4, 6 and 7), at least two valid efforts should be 

2015N231308_03
CONFIDENTIAL
201832
51
obtained.  At each time point, the largest FEV1 and FVC should be recorded, even if they 
do not come from the same effort. 
Serial FEV1 measurements only (not FVC) will be conducted serially as described in 
Time and Events Table Table 3 following each exercise challenge at Visits 2, 3, 4, 6 and 
7. 
Subjects must have a FEV1 of at least 70% of their predicted normal value to be eligible 
to take part in the study at Visit 1.
After Visit 1, subjects will always be required to withhold their albuterol/salbutamol for 
at least 6 hours before each clinic visit.
Subjects must not administer study drug prior to coming to the clinic on study visit days.
8.3.1.1.
Target FEV1 Calculations
Three target FEV1values will be calculated from the pre-exercise FEV1 to determine 
subject eligibility and for monitoring the safety of the subject prior to exercise challenge 
testing: 
1.
The FEV1 value that represents a ≥20% decrease in FEV1, which is the 
eligibility criterion. 
2.
The FEV1 value that represents a ≥40% decrease in FEV1, which will serve as 
an alert for severe bronchoconstriction and need for administering rescue 
treatment. 
3.
The FEV1 value that represents a ≥95% recovery of the FEV1 result.  
Subjects should be monitored until they reach a recovery level where their FEV1 value 
represents a 95% recovery of the pre-exercise FEV1 result.  Additional spirometry and 
rescue medication may be used as needed (See Section 8.3.2.1).
8.3.2.
Exercise Challenge Testing
The exercise challenge test is a stepped challenge on a treadmill at a speed and incline 
that will allow the subject’s heart rate to reach between 80% to 95% of their maximum 
heart rate. All exercise challenges will be performed on a treadmill. During the exercise 
challenge, subjects will breathe medical grade dry air at ambient temperature from a 
reservoir using a two-way non-rebreathing valve.
Subjects will exercise sufficiently to attain a heart rate between 80 to 95% of their 
predicted maximum within 4 minutes and maintain this heart rate with exercise for an 
additional 6 minutes for a total of 10 minutes of exercise. The challenge will be followed 
immediately by serial spirometry (FEV1 efforts only) at 6 time points over 60 minutes (5, 
10, 15, 30, 45 and 60 minutes post-exercise). The information gained from the eligibility 
challenge(s) regarding incline and speed will be used to obtain the target heart rate in the 
subsequent exercise challenges.

2015N231308_03
CONFIDENTIAL
201832
52
Exercise challenges should not be performed within 24 hours of exercise in cold air. 
Subjects should abstain from drinking beverages with high caffeine content such as tea or 
coffee for 4 hours prior to the exercise challenge. 
Additional instructions on exercise challenge testing can be found in the SRM.
8.3.2.1.
Worsening of Asthma during Exercise Challenge
Exercise challenges may be stopped at any time during the assessment for worsening 
asthma. Guidelines for treatment are provided in the SRM. 
If a subject's FEV1 decreases to ≥40% from their pre-exercise FEV1 following exercise 
challenge, he/she must receive rescue therapy. If he/she requires rescue therapy with 
anything other than MDI or nebulized albuterol/salbutamol or ipratropium (secondarily) 
following the exercise challenge assessment, he/she is not allowed to continue in the 
study (see Section 6.4.1). 
The subject should not leave the clinic until FEV1 returns to within 95% of the baseline 
FEV1 target recovery value or the subject is judged medically stable by the investigator to 
leave the clinic.
8.3.3.
Key Study Assessments
Information regarding spirometry, exercise testing, and study medication dosing at Visits 
will be conducted as described below. All other assessments will also be conducted as 
shown in Time and Events Table Table 3.
8.3.3.1.
Visit 1 (Screening)
Spirometry will be performed at Visit 1 between 5:00 PM and 11:00 PM, ideally at the 
end of the subjects ICS dosing interval. Full FEV1 and FVC testing will be conducted. At 
least two valid and two repeatable spirometry efforts should be obtained. Subjects must 
have a best pre-bronchodilator FEV1 of ≥ 70% of their predicted normal value to be 
eligible to take part in the study.  
8.3.3.2.
Visit 2 (Randomization)
Treatment period 1 baseline FEV1: Visit 2 begins between 5 PM and 11 PM and 
should begin at approximately the same time as Visit 1 (±1 hour).  Spirometry will be 
performed at Visit 2 at approximately the same time as at Visit 1 (±1 hour). The FEV1
should be measured approximately 12 hours (±1 hour) after dosing with run-in 
medication (FP 250 mcg). At least two valid and two repeatable spirometry efforts should 
be obtained before the first exercise challenge.
From this spirometry testing, the target FEV1 values #2 and #3 (Section 8.3.1.1) should 
be determined based on the pre-exercise FEV1. 

2015N231308_03
CONFIDENTIAL
201832
53
Eligibility Exercise Challenge: After the pre-exercise baseline FEV1 has been 
determined, an exercise challenge will be performed according to the method described 
in the SRM. 
Post-exercise Serial Spirometry: Following the eligibility exercise challenge, serial 
spirometry (FEV1) will be performed at 5, 10, 15, 30, 45 and 60 minutes post-exercise. 
To qualify for randomization, subjects must demonstrate a decrease in FEV1 of ≥20% 
when compared to the FEV1 obtained immediately pre-exercise for at least one of the 
post-exercise spirometry efforts obtained within 30 minutes post-challenge.  Subjects 
who achieve a decrease in FEV1 of 15% to <20% may continue taking their daily run-in 
medication and repeat the eligibility exercise challenge once within a week. In the event 
where a repeat visit is required for the exercise challenge, spirometry and vital signs 
measurements will be performed pre- and post- exercise challenge as detailed in Table 3. 
In addition, ACQ-5 and a review of concomitant medication and adverse events will be 
performed at the repeat visit. 
Dosing: Eligible subjects will administer their evening dose of double-blinded study 
medication following the eligibility exercise challenge/serial spirometry. Evening dosing 
should occur between 5 PM and 11PM.
8.3.3.3.
Visit 3 and Visit 6 (23 hours Post First Dose Exercise Challenge)
Visit 3 and Visit 6 begins between 5 PM and 11 PM and should begin at approximately 
the same time as Visit 1 (±1 hour).  These visits should begin prior to the subject’s 
evening dose on that visit day.
Pre-exercise FEV1: Spirometry will be performed at Visits 3 and 6 at approximately the 
same time as at Visit 1 (±1 hour). The FEV1 should be measured approximately 23 hours 
(±1 hour) after the first dose in each treatment period. At least two valid spirometry 
efforts should be obtained before the exercise challenge.
From this spirometry testing, the target FEV1 values #2 and #3 (Section 8.3.1.1) should 
be determined based on the pre-exercise FEV1. 
Exercise Challenge: After the pre-exercise FEV1 has been determined, an exercise 
challenge will be performed according to the method described in the SRM. 
Post-exercise Serial Spirometry: Following the eligibility exercise challenge at each 
visit, serial spirometry (FEV1) will be performed at 5, 10, 15, 30, 45 and 60 minutes post-
exercise.
Medication Dosing: At the end of Visits 3 and 6, the evening dose of study treatment 
medication should be administered following completion of the 23-hour post evening 
dose exercise challenge/serial spirometry, and prior to the subject’s leaving the clinic.

8.3.3.4.
Visit 4 and Visit 7 (Blinded Treatment Exercise Challenges)
Visit 4 and Visit 7 begin between 5 PM and 11 PM and are conducted over 
approximately 24 hours. Subjects will be required to attend three clinic visits during each 
24-hour period for Visit 4 and Visit 7. The evening visit should begin at approximately 
the same time as Visit 1 (±1 hour).  
Dosing: At the beginning of Visit 4 and Visit 7, subjects will administer their evening 
doses of double-blinded study medication in the clinic and the time of dosing will be 
recorded. In addition to administering the evening dose, vital signs will be measured and 
a review of concomitant medication and AEs performed.
Subjects will return to the clinic 12 (±1) hours and 23 (±1) hours after evening 
dosing for exercise challenge testing.
Pre-exercise FEV1: At least two valid spirometry efforts with full FEV1 and FVC 
maneuvers should be obtained just prior to each exercise challenge.
From this spirometry testing, the target FEV1 values #2 and #3 (Section 8.3.1.1) should 
be determined based on the pre-exercise FEV1. 
Exercise challenge testing: Exercise challenge testing will occur at 12 (±1) hours and 23 
(±1) hours after administering the evening dose. (The 12-hour exercise challenge and 
spirometry measurements should occur prior to dosing of the study medication). 
Post-exercise Serial Spirometry: Following the eligibility exercise challenge at each 
visit, serial spirometry (FEV1) will be performed at 5, 10, 15, 30, 45 and 60 minutes post-
exercise.
Washout Medication Dosing: At the end of Visit 4, the washout medication should be 
dispensed and first evening dose administered following completion of the 23-hour post 
evening dose exercise challenge/serial spirometry, and prior to the subject’s leaving the 
clinic.
8.3.3.5.
Visit 5
Treatment period 2 baseline FEV1: Spirometry will be performed at Visit 5 at 
approximately the same time as at Visit 1 (±1 hour). The FEV1 should be measured 
approximately 12 hours (±1 hour) after dosing with the washout medication. At least two 
valid spirometry efforts should be obtained.
Dosing: Subjects will administer their evening doses of double-blinded study medication 
following the spirometry.
8.3.4.
Physical Activity Monitor
Subjects should refrain from significant changes in their exercise level (e.g., joining a
gym), except as instructed by the investigator, for the duration of the study.

A clinically validated physical activity monitor (accelerometer) will be used to measure 
specific levels of physical activity. There will be 4 assessment periods, including an 
initial baseline assessment in order to provide a reliable estimate of habitual physical 
activity. The physical activity monitor will be worn by the study subjects during the 
weeks prior to Visit 2, Visit 4, Visit 5 and Visit 7. Further details will be provided in the 
SRM.
Subjects will be contacted by telephone 8-9 days prior to Visits 2, 4, 5 and 7 and 
reminded to wear the SenseWear Armband accelerometer for the 7 days preceding these 
visits.
Physical activity monitors will be shipped from each study site directly to GSK for 
analysis and interpretation or to an independent vendor, contracted by GSK, blinded to 
treatment assignment, who will be responsible for transmitting the data to GSK.
8.3.5.
Asthma Control Questionnaire-5 (ACQ-5)
The ACQ-5 will be completed at the beginning of all study visits where the form is 
completed. 
The ACQ-5 is a five-item questionnaire, which has been developed as a measure of 
subject’ asthma control that can be quickly and easily completed [Juniper, 2005]. The 
questions are designed to be self-completed by the subject. The five questions enquire 
about the frequency and/or severity of symptoms (nocturnal awakening on waking in the 
morning, activity limitation, and shortness of breathe, wheeze). The response options for 
all these questions consist of a zero (no impairment/limitation) to six (total impairment/ 
limitation) scale.
The subject should be given a quiet area in which to complete the questionnaire. The 
investigator should ask the subject to complete the questions as accurately as possible. If 
the subject requests help or clarification with any of the questions, he/she will be asked to 
re-read the instructions and give the answer that best reflects how he/she felt over the 
previous week. The subject should be reassured that there are no right or wrong 
answers. The investigator should not provide the subject with any answer or attempt to 
interpret any portion of a question.
It is recommended that the ACQ-5 be administered at the same time during each visit.
To avoid biasing responses, the subjects should not be told the results of diagnostic tests 
prior to completing the questionnaire and should be completed before any procedures are 
performed on the subject to avoid influencing the subject’s response. Adequate time 
should be allowed to complete all items on the ACQ-5.
8.4.
Safety
Safety will be assessed, as indicated in the Time and Events Table Table 3, by monitoring 
of AEs, a physical examination at screening, and vital signs (systolic and diastolic blood 
pressure and heart rate [pulse] at each visit. A screening 12-ECG will be conducted. 

2015N231308_03
CONFIDENTIAL
201832

In cases of suspected pneumonia, a confirmatory chest x-ray should be conducted within 
48 hours.
Planned time points for all safety assessments are listed in the Time and Events Table 
(Time and Events Table 3). 
8.4.1.
Adverse Events (AE) and Serious Adverse Events (SAEs)
The definitions of an AE or SAE can be found in Appendix 5.
The investigator and their designees are responsible for detecting, documenting and 
reporting events that meet the definition of an AE or SAE. 
8.4.1.1.
Time period and Frequency for collecting AE and SAE information

AEs and SAEs will be collected from the start of Study Treatment (the start of the 
run-in period) until the follow-up contact (see Section 8.4.1.3), at the time points 
specified in the Time and Events Table Table 3).

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 eCRF.

Any SAEs assessed as related to study participation (e.g., protocol-mandated 
procedures, invasive tests, or change in existing therapy) or related to a GSK 
product will be recorded from the time a subject consents to participate in the 
study up to and including any follow-up contact. 

All SAEs will be recorded and reported to GSK within 24 hours, as indicated in 
Appendix 5.

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 5.
8.4.1.2.
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?” 

2015N231308_03
CONFIDENTIAL
201832
57

“Have you taken any new medicines, other than those provided in this study, since 
your last visit/contact?” 
8.4.1.3.
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 5.6.1) 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 6.4). Further information on follow-up procedures is given in 
Appendix 5.
8.4.1.4.
Cardiovascular and Death Events
For any cardiovascular events detailed in Appendix 5 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 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.
8.4.1.5.
Regulatory Reporting Requirements for SAEs
Prompt notification by the investigator to GSK of SAEs and non-serious AEs related to 
study treatment (even for non- interventional post-marketing studies) is essential so that 
legal obligations and ethical responsibilities towards the safety of subjects and the safety 
of a product under clinical investigation are met. 
GSK has a legal responsibility to notify both the local regulatory authority and other 
regulatory agencies about the safety of a product under clinical investigation.  GSK will 
comply with country specific regulatory requirements relating to safety reporting to the 
regulatory authority, Institutional Review Board (IRB)/Independent Ethics Committee 
(IEC) and investigators.
Investigator safety reports are prepared for suspected unexpected serious adverse 
reactions according to local regulatory requirements and GSK policy and are forwarded 
to investigators as necessary.
An investigator who receives an investigator safety report describing a SAE(s) or other 
specific safety information (e.g., summary or listing of SAEs) from GSK will file it with 
the IB and will notify the IRB/IEC, if appropriate according to local requirements.

8.4.2.
Asthma Exacerbations
Severe asthma exacerbations should not be recorded as an AE unless they meet the 
definition of an SAE (Section 13.5.2).  For the purposes of this study, severe asthma 
exacerbations will be collected and recorded on the exacerbations log in the eCRF. The 
treatment details must also be recorded in the eCRF. 
The time period for collection of severe asthma exacerbations will begin from the time of 
randomization (first receipt of investigational product) and will end after the 7-day 
follow-up period has been completed.
8.4.3.
Pregnancy

Details of all pregnancies in female subjects will be collected from the time the 
informed consent is signed (Visit 1) and until the follow up contact.

Any pregnancy that occurs during study participation must be reported using a 
clinical trial pregnancy form.  

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 Section 
13.6.1.

Any SAE occurring in association with a pregnancy, brought to the investigator’s 
attention after the subject has completed the study and considered by the investigator 
as possibly related to the study treatment, must be promptly reported to GSK.
8.4.4.
Physical Exams

A detailed physical examination including, but not limited to an evaluation of the 
lungs and cardiovascular system, will be conducted at Visit 1.  Investigators 
should pay special attention to clinical signs related to previous serious illnesses

Licensed practitioners who are listed on the Form 1572 are permitted to perform 
the physical examination. A licensed physician on the Form 1572 must sign off on 
the physical examinations completed by non-physicians. The results will be 
recorded in the subject’s clinic notes. Whenever possible, the same person should 
perform the examination. 

If during routine clinical examination of the subject there is evidence of oral 
candidiasis infection, a culture can be taken and appropriate therapy should be 
instituted at the discretion of the Investigator.
8.4.5.
Vital Signs

Vital signs including pulse rate and systolic and diastolic blood pressure will be 
obtained at each clinic visit, including any Early Withdrawal visit. 

Vital signs will be obtained after subjects have rested for approximately 5 minutes 
in a semi-supine position, except in the case of the post exercise test vital signs 
which will be performed immediately following the end of the exercise test.


At all time points where both vital signs and spirometry are performed, vital signs 
will be done before the spriometry measurement. 

At visits where the exercise challenge is performed, vitals will be measured before 
(prior to the pre-exercise spirometry) and after the exercise challenge.

Heart rate will be measured during each exercise challenge. 

If there are any clinically significant abnormalities noted, further examinations 
must be performed until the abnormality is resolved.  
8.4.6.
Electrocardiogram (ECG)

A 12-lead ECG will be performed and interpreted by the investigator or his/her 
suitably qualified designee at Visit 1. The ECG will be recorded after 5 minutes 
rest; after vital signs and prior to performing spirometry.

Investigators will use a site ECG machine and perform a manual reading of the 
ECG parameters to determine whether a subject meets the eligibility criteria for 
enrolment in the study at screening (Visit 1). 

The ECG interpretation including the paper trace will be maintained at the site 
within the source documentation.
8.5.
Genetics
Information regarding genetic research is included in Appendix 4.

STATISTICAL CONSIDERATIONS AND DATA 
ANALYSES
10.1.
Hypotheses
The primary endpoint is the maximal percent decrease in FEV1 following exercise 
challenge at 12-hours post-dose at the end of the 2-week treatment period.  
The treatment comparison is the FF/VI combination versus FP.  Demonstration of 
efficacy for this treatment comparison will be based on a hypothesis testing approach 
whereby the null hypothesis is that there is no difference between treatment groups and 
the alternative hypothesis is that there is a difference between treatment groups.  
A 2-sided 5% probability associated with incorrectly rejecting the null hypothesis 
(significance level) is considered acceptable for this study. In order to account for 
multiplicity, this primary hypothesis test on the primary endpoint for the ITT (Intent-to-
Treat) population will act as a gatekeeper for all other hypothesis tests using the 
secondary endpoints, where these tests will proceed in a pre-defined order.
If the primary hypothesis on the primary endpoint for the ITT population is rejected then 
the following hierarchy of tests will be performed using the ITT population; 
1.
Test at the 5% level the null hypothesis that the true odds ratio between the two treatment 
groups of recovering to within 5% of pre-exercise FEV1 at the 30 minute post-exercise 
time point following the exercise challenge at 12 hours post evening dose is equal to one.
2.
Test at the 5% level the null hypothesis that the true population difference 
between the treatment group means in maximal percent decrease in FEV1 from 
pre-exercise at 23 hrs post-dose at the end of the 2-week treatment period is zero.
3.
Test at the 5% level the null hypothesis that the true odds ratio between the two treatment 
groups of recovering to within 5% of pre-exercise FEV1 at the 30 minute post-exercise 
time point following the exercise challenge at 23 hours post evening dose is equal to one.
4.
If 3 is significant then test at the 5% level the null hypothesis that the true 
population difference between the treatment group means in weighted mean 0-60

201832
61
minutes for percentage decrease in FEV1 from pre-exercise FEV1 at 12 hrs post-
dose at the end of the 2-week treatment period is zero.
5.
If 4 is significant then test at the 5% level the null hypothesis that the true 
population difference between the treatment group means in weighted mean 0-60 
minutes for percentage decrease in FEV1 from pre-exercise FEV1 at 23 hrs post-
dose at the end of the 2-week treatment period is zero.
If either the primary null hypothesis or any of the above null hypotheses are not rejected, 
then although all of the subsequent hypothesis tests will be performed, each test result, 
and the associated p-value will be used for descriptive purposes only.
10.2.
Study Design Considerations
10.2.1.
Sample Size Assumptions
For the primary efficacy endpoint of maximal percent decrease in FEV1 following 
exercise challenge at 12 hours post-dose at the end of the 2-week treatment period, given 
an assumed 20% screen failure rate, a 70% run-in failure rate, and a 15% withdrawal rate 
post-randomisation, a total of approximately 275 subjects will be screened. Given these 
assumed failure and withdrawal rates we expect 220 subjects will enter the run-in period, 
of which 66 subjects will be randomized, of which 56 subjects will be evaluable, that is 
completing the exercise challenges and the FEV1 evaluations at the end of both treatment 
periods. With 56 evaluable subjects this study has approximately 90% power assuming a 
true population difference of 5% in maximal percent decrease in FEV1 between the two 
treatment groups.  This assumes a within-subject standard deviation (SD) of 8% where 
significance is declared at the two-sided 5% significance level. 
Subjects will be centrally randomized to one of the two treatment sequences shown 
below in Table 4 in a 1:1 ratio:

Sample Size Re-estimation
Blinded sample size re-estimation will be conducted when approximately 50% of the 
subjects have completed their second exercise challenge. In order to assess the accuracy 
of the sample size assumption for the within-subject SD, the linear mixed model for the 
primary analysis will be fitted to this blinded interim data, but with a dummy variable to 
denote treatment group membership. If this suggests the original assumptions behind the 
sample size were incorrect, an adjustment may be made to the planned number of 
subjects to be recruited.

Data Analysis Considerations
10.3.1.
Analysis Populations
Three subject populations will be identified.
Total Population: This population will comprise of all subjects screened and for whom a 
record exists on the study database and will be used for the tabulation and listing of 
reasons for withdrawal before randomization.
Intent-to-Treat (ITT) Population: The ITT Population will comprise all subjects 
randomized to treatment and who received at least one dose of trial medication.  
Randomized subjects will be assumed to have received trial medication unless definitive 
evidence to the contrary exists.  This will constitute the primary population for all 
analyses of efficacy measures and safety measures. Outcomes will be reported according 
to the randomized treatment allocation.
Per Protocol (PP) Population: The PP Population will consist of all subjects in the ITT
Population who do not have full protocol deviations.  Protocol deviations can either be 
full or partial.  Subjects with only partial deviations will be considered part of the PP 
population but their data will be excluded from the date of their deviation until either the 
end of the study or the end of the treatment period in which the deviation occurred.  The 
decision to exclude a subject, or part of their data, from the PP Population will be made 
prior to breaking the blind.  Protocol deviations that will lead to full or partial exclusion 
from the PP population will be detailed in the Reporting and Analysis Plan (RAP).  This 
population will be used for confirmatory analyses of the primary efficacy endpoint only.
10.3.2.
Analysis Data Sets
Details of the derived data in analysis datasets to be created will be given in the RAP.
10.3.3.
Treatment Comparisons
10.3.3.1.
Primary Comparisons of Interest
The primary treatment comparison is the comparison of group means for the FF/VI 
combination and FP for the primary endpoint of maximal percent decrease in FEV1 from 
pre-exercise at 12 hrs post-evening dose at the end of the 2-week treatment period. This 
comparison is to be performed using the ITT Population.
10.3.3.2.
Other Comparisons of Interest
The primary treatment comparison of FF/VI combination versus FP for the primary 
endpoint will also be performed for the PP population.
In addition FF/VI combination will be compared to FP for the secondary and other 
efficacy endpoints.

10.4.
Key Elements of Analysis Plan
Where possible, data from subjects who withdraw prematurely from the study will be 
included in any analyses. Specific details for inclusion will be detailed in the RAP but, in 
general, if a subject has completed a treatment period, including both exercise challenges 
and FEV1 evaluations, then the data for that period will be included in the analysis. 
Specifically if a subject has completed the first exercise challenge at 12 hours post-dose, 
as well as the FEV1 evaluations after this challenge, but has not completed the second 
exercise challenge at 23 hours post-dose, then the data for the 12 hour post-dose time 
point will be included, but will not be carried forward to replace the missing 23 hour time 
point.
Any tests for interactions will be 2-sided at the 10% level of significance.  In all cases, if 
any assumptions of the proposed methods of analyses are not met, alternative methods of 
analyses will be used.
The baseline FEV1 for all endpoints will be the pre-treatment FEV1 value obtained at the 
start of each Treatment Period (Visit 2 or Visit 5).
10.4.1.
Efficacy Analyses
All efficacy data will be summarized using means, standard deviations, medians and 
ranges for continuous variables and frequencies and percentages for categorical variables.
10.4.1.1.
Primary Analysis
The primary efficacy end point is maximal percent decrease from pre-exercise FEV1
following exercise challenge at 12 hours post-dose following two weeks of treatment. 
Maximal percent decrease will be defined as the percent change from pre-exercise FEV1
to the minimum FEV1 collected within one hour following exercise challenge at 12 hours 
post-dose.  Pre-exercise FEV1 will be defined as the FEV1 value collected prior to the 
exercise challenge test at 12 hours post-dose.  
The primary analysis is a comparison of the estimated means of the two treatment groups 
in maximal percent decrease in FEV1 from pre-exercise at 12 hrs post-dose using a LMM 
to adjust for covariate effects. The LMM will include the following covariates: treatment, 
subject-level mean of the pre-treatment FEV1 period baselines (mean of the 2 period 
baselines per subject), centered period-level baseline FEV1 (period baselines centered 
using subject-level mean of the pre-treatment FEV1 period baselines), gender, age, 
treatment period and smoking history as fixed effects, and a random intercept for each 
subject.

Details will be provided in the RAP of alternative analyses methods to be used in the 
event that distributional assumptions do not hold (e.g. if the distribution appears to be 
heavily skewed).
Mean post-exercise minimum FEV1 measurements and mean maximal percent decrease 
from pre-exercise FEV1 will be summarized with descriptive statistics by treatment 
group. Summaries and analyses for the primary endpoint will be provided for both the 
ITT and PP populations.  
10.4.1.2.
Secondary Analyses
Summaries and analyses for secondary endpoints will be provided for the ITT population.  
Maximal percent decrease from pre-exercise FEV1 following exercise challenge (at 23 
hours post-dose at the end of the 2-week treatment period):
This endpoint will be summarized and analyzed as for the primary endpoint of maximal 
percent decrease from pre-exercise FEV1 following exercise challenge at 12 hours post-
dose.  
Proportion of subjects with a 30 minute post-challenge FEV1 that was no more than 
5% lower than their pre-exercise FEV1 following the exercise challenge at 12 hours 
and 23 hours post evening dose at the end of the 2-week treatment period
This endpoint will be analysed using a logistic regression model separately for the 12 and 
23 hour challenges using the covariates baseline FEV1, treatment group, gender, age, and 
smoking history.
Weighted mean 0-60 minutes for percentage decrease from pre-exercise FEV1 after 
exercise (at 12 hours and 23 hours post-dose at the end of the 2-week treatment 
period):
A comparison will be made of the estimated means of the two treatment groups in for 
weighted mean 0-60 minutes of the percentage decrease in FEV1 from pre-exercise at 12 
and 23 hrs post-dose using a LMM to adjust for covariate effects. The LMM will include 
the following covariates: treatment, subject-level mean of the pre-treatment FEV1 period 
baselines (mean of the 2 period baselines per subject), centered period-level baseline 
FEV1 (period baselines centered using subject-level mean of the pre-treatment FEV1
period baselines),  gender, age, treatment period and smoking history as fixed effects, and 
a random intercept for each subject.  
10.4.1.2.1. Other Efficacy Analyses
Other measures of efficacy include the evaluation of a categorical treatment response 
evaluating the percentage of subjects who demonstrate a decrease from pre-exercise 
challenge FEV1<10%, a decrease 10% to <20%, or a decrease 20%, and an evaluation 
of maximal percent decrease from  treatment period baseline in FEV1 (period baseline) 
following exercise challenge (at 12 hours and 23 hours post-dose).  Additional endpoints

include evaluation of physical activity monitoring the ACQ-5 score, and the proportion of 
subjects with a 5 minute post-challenge FEV1 that was no more than 5% lower than their 
pre-exercise FEV1 following the exercise challenge at 12 hours and 23 hours post 
evening dose at the end of the 2-week treatment period (repeat for the 10, 15, 45 and 60 
minute time points).

Adverse Events (AEs)
Frequency of adverse events will be tabulated by treatment group as the number of 
subjects with events occurring during the treatment period.  Drug-related adverse events 
will be tabulated in the same manner.  Subject listings will include all reported adverse 
events, all adverse events rated as serious and all adverse events leading to study 
discontinuation.

The study will be conducted in accordance with all applicable regulatory requirements, 
and with GSK policy.
The study will also be conducted in accordance with ICH Good Clinical Practice (GCP), 
all applicable subject privacy requirements, and the guiding principles of the current 
version of the Declaration of Helsinki.  This includes, but is not limited to, the following:

IRB/IEC review and favorable opinion/approval of the study protocol and 
amendments as applicable

Obtaining signed informed consent

Investigator reporting requirements (e.g. reporting of AEs/SAEs/protocol 
deviations to IRB/IEC)

GSK will provide full details of the above procedures, either verbally, in writing, 
or both.

written approval of the clinical protocol should state that approval of optional 
assessments is being deferred and the study, with the exception of the optional 
assessments, can be initiated.
11.3.
Quality Control (Study Monitoring)

In accordance with applicable regulations including GCP, and GSK procedures, 
GSK monitors will contact the site prior to the start of the study to review with the 
site staff the protocol, study requirements, and their responsibilities to satisfy 
regulatory, ethical, and GSK requirements.  

When reviewing data collection procedures, the discussion will also include 
identification, agreement and documentation of data items for which CRF will 
serve as the source document.
GSK will monitor the study and site activity to verify that the:

Data are authentic, accurate, and complete.

Safety and rights of subjects are being protected.

Study is conducted in accordance with the currently approved protocol and any 
other study agreements, GCP, and all applicable regulatory requirements.

201832
68
The investigator and the head of the medical institution (where applicable) agrees to 
allow the monitor direct access to all relevant documents
11.4.
Quality Assurance

To ensure compliance with GCP and all applicable regulatory requirements, GSK 
may conduct a quality assurance assessment and/or audit of the site records, and 
the regulatory agencies may conduct a regulatory inspection at any time during or 
after completion of the study. 

In the event of an assessment, audit or inspection, the investigator (and institution) 
must agree to grant the advisor(s), auditor(s) and inspector(s) direct access to all 
relevant documents and to allocate their time and the time of their staff to discuss 
the conduct of the study, any findings/relevant issues and to implement any 
corrective and/or preventative actions to address any findings/issues identified.
11.5.
Study and Site Closure

Upon completion or premature discontinuation of the study, the GSK monitor will 
conduct site closure activities with the investigator or site staff, as appropriate, in 
accordance with applicable regulations including GCP, and GSK Standard 
Operating Procedures.

GSK reserves the right to temporarily suspend or prematurely discontinue this 
study at any time for reasons including, but not limited to, safety or ethical issues 
or severe non-compliance. For multicenter studies, this can occur at one or more 
or at all sites.  

If GSK determines such action is needed, GSK will discuss the reasons for taking 
such action with the investigator or the head of the medical institution (where 
applicable).  When feasible, GSK will provide advance notification to the 
investigator or the head of the medical institution, where applicable, of the 
impending action.

If the study is suspended or prematurely discontinued for safety reasons, GSK will 
promptly inform all investigators, heads of the medical institutions (where 
applicable) and/or institution(s) conducting the study. GSK will also promptly 
inform the relevant regulatory authorities of the suspension or premature 
discontinuation of the study and the reason(s) for the action.  

If required by applicable regulations, the investigator or the head of the medical 
institution (where applicable) must inform the IRB/IEC promptly and provide the 
reason for the suspension or premature discontinuation.
11.6.
Records Retention

Following closure of the study, the investigator or the head of the medical 
institution (where applicable) must maintain all site study records (except for 
those required by local regulations to be maintained elsewhere), in a safe and 
secure location.  

2015N231308_03
CONFIDENTIAL
201832
69

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.
11.7.
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.
A manuscript will be progressed for publication in the scientific literature if the results 
provide important scientific or medical knowledge.

Appendix 4: Genetic Research
Genetic Research Objectives and Analyses
The objectives of the genetic research are to investigate the relationship between genetic 
variants and: 

Response to medicine, including FF/VI, FP or any concomitant medicines;

Asthma susceptibility, severity, and progression and related conditions
Genetic data may be generated while the study is underway or following completion of 
the study.  Genetic evaluations may include focused candidate gene approaches and/or 
examination of a large number of genetic variants throughout the genome (whole genome 
analyses). Genetic analyses will utilize data collected in the study and will be limited to 
understanding the objectives highlighted above.  Analyses may be performed using data 
from multiple clinical studies to investigate these research objectives.
Appropriate descriptive and/or statistical analysis methods will be used. A detailed 
description of any planned analyses will be documented in a Reporting and Analysis Plan 
(RAP) prior to initiation of the analysis. Planned analyses and results of genetic 
investigations will be reported either as part of the clinical RAP and study report, or in a 
separate genetics RAP and report, as appropriate.
Study Population
Any subject who is enrolled in the study can participate in genetic research.  Any subject 
who has received an allogeneic bone marrow transplant must be excluded from the 
genetic research.
Study Assessments and Procedures
A key component of successful genetic research is the collection of samples during 
clinical studies. Collection of samples, even when no a priori hypothesis has been 
identified, may enable future genetic analyses to be conducted to help understand 
variability in disease and medicine response.  

A 2 ml saliva sample will be taken for Deoxyribonucleic acid (DNA) extraction. 
A saliva sample is collected at the randomisation visit, after the subject has been 
randomized and provided informed consent for genetic research. Instructions for 
collection and shipping of the genetic sample are described in the laboratory 
manual. The DNA from the saliva sample may undergo quality control analyses to 
confirm the integrity of the sample. If there are concerns regarding the quality of 
the sample, then the sample may be destroyed. The saliva sample is taken on a 
single occasion unless a duplicate sample is required due to an inability to utilize 
the original sample.  
The genetic sample is labelled (or “coded”) with the same study specific number used to 
label other samples and data in the study.  This number can be traced or linked back to 

2015N231308_03
CONFIDENTIAL

81
the subject by the investigator or site staff. Coded samples do not carry personal 
identifiers (such as name or social security number). 
Samples will be stored securely and may be kept for up to 15 years after the last subject 
completes the study, or GSK may destroy the samples sooner.  GSK or those working 
with GSK (for example, other researchers) will only use samples collected from the study 
for the purpose stated in this protocol and in the informed consent form.  Samples may be 
used as part of the development of a companion diagnostic to support the GSK medicinal 
product.
Subjects can request their sample to be destroyed at any time.
Informed Consent
Subjects who do not wish to participate in the genetic research may still participate in the 
study.  Genetic informed consent must be obtained prior to any saliva being taken.
Subject Withdrawal from Study
If a subject who has consented to participate in genetic research withdraws from the 
clinical study for any reason other than being lost to follow-up, the subject will be given a 
choice of one of the following options concerning the genetic sample, if already 
collected:

Continue to participate in the genetic research in which case the genetic DNA 
sample is retained

Discontinue participation in the genetic research and destroy the genetic DNA 
sample 
If a subject withdraws consent for genetic research or requests sample destruction for any 
reason, the investigator must complete the appropriate documentation to request sample 
destruction within the timeframe specified by GSK and maintain the documentation in 
the site study records. 
Genotype data may be generated during the study or after completion of the study and
may be analyzed during the study or stored for future analysis. 

If a subject withdraws consent for genetic research and genotype data has not been 
analyzed, it will not be analyzed or used for future research.  

Genetic data that has been analyzed at the time of withdrawn consent will 
continue to be stored and used, as appropriate. 
Screen and Baseline Failures
If a sample for genetic research has been collected and it is determined that the subject 
does not meet the entry criteria for participation in the study, then the investigator should 
instruct the subject that their genetic sample will be destroyed. No forms are required to 
complete this process as it will be completed as part of the consent and sample

82
reconciliation process.  In this instance a sample destruction form will not be available to 
include in the site files.
Provision of Study Results and Confidentiality of Subject’s Genetic Data
GSK may summarize the genetic research results in the clinical study report, or 
separately and may publish the results in scientific journals. 
GSK may share genetic research data with other scientists to further scientific 
understanding in alignment with the informed consent. GSK does not inform the subject, 
family members, insurers, or employers of individual genotyping results that are not 
known to be relevant to the subject’s medical care at the time of the study, unless 
required by law. This is due to the fact that the information generated from genetic 
studies is generally preliminary in nature, and therefore the significance and scientific 
validity of the results are undetermined.  Further, data generated in a research laboratory 
may not meet regulatory requirements for inclusion in clinical care.

Appendix 5: Definition of and Procedures for Recording, 
Evaluating, Follow-Up and Reporting of Adverse Events
13.5.1.
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).

"Lack of efficacy" or "failure of expected pharmacological action" per se will not be 
reported as an AE or SAE.  However, the signs and symptoms and/or clinical 
sequelae resulting from lack of efficacy will be reported if they fulfil the definition
of an AE or SAE.

The signs and symptoms and/or clinical sequelae resulting from lack of efficacy will 
be reported if they fulfil the definition of an AE or SAE.  Also, "lack of efficacy" or 
"failure of expected pharmacological action" also constitutes an AE or SAE.
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 

2015N231308_03
CONFIDENTIAL
201832
84
Events NOT meeting definition of an AE include:
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 
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.
13.5.2.
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

2015N231308_03
CONFIDENTIAL
201832
85
Serious Adverse Event (SAE) is defined as any untoward medical occurrence that, 
at any dose:
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
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.
See Appendix 3 for the required liver chemistry follow-up instructions

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

Revascularization
13.5.4.
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.

Subject-completed Value Evidence and Outcomes questionnaires and the collection 
of AE data are independent components of the study.

Responses to each question in the Value Evidence and Outcomes questionnaire will 
be treated in accordance with standard scoring and statistical procedures detailed by 
the scale’s developer.

2015N231308_03
CONFIDENTIAL
201832
87

The use of a single question from a multidimensional health survey to designate a 
cause-effect relationship to an AE is inappropriate.
13.5.5.
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 
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.

2015N231308_03
CONFIDENTIAL
201832
88

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.
13.5.6.
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 

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 by telephone.

Contacts for SAE receipt can be found at the beginning of this protocol on the 
Sponsor/Medical Monitor Contact Information page.

SAE reporting to GSK via paper CRF

Facsimile transmission of the SAE paper CRF is the preferred method to transmit 
this information to the Medical Monitor 

In rare circumstances and in the absence of facsimile equipment, notification by 
telephone is acceptable, with a copy of the SAE data collection tool sent by 
overnight mail

Initial notification via the telephone does not replace the need for the investigator to 
complete and sign the SAE CRF pages within the designated reporting time frames.

Contacts for SAE receipt can be found at this beginning of the protocol on the 
Sponsor/Medical Monitor Contact Information page.

(FRP) and Collection of Pregnancy Information
This list does not apply to FRP with same sex partners, when this is their preferred and
usual lifestyle or for subjects who are and will continue to be abstinent from penile-
vaginal intercourse on a long term and persistent basis. 

Contraceptive subdermal implant 

Intrauterine device or intrauterine system 

Oral Contraceptive, either combined or progestogen alone [Hatcher, 2007] 

Injectable progestogen [Hatcher, 2007]

Contraceptive vaginal ring [Hatcher, 2007]

Percutaneous contraceptive patches [Hatcher, 2007]

Male partner sterilization with documentation of azoospermia prior to the female 
subject's entry into the study, and this male is the sole partner for that subject 
[Hatcher, 2007].  

Male condom plus partner use of one of the contraceptive options below:
o
Contraceptive subdermal implant 
o
Intrauterine device or intrauterine system 
o
Oral Contraceptive, either combined or progestogen alone [Hatcher, 2007]
Injectable progestogen [Hatcher, 2007]
o
Contraceptive vaginal ring [Hatcher, 2007]
o
Percutaneous contraceptive patches [Hatcher, 2007]
This is an all inclusive list of those methods that meet the GSK definition of highly 
effective: having a failure rate of less than 1% per year when used consistently and, 
correctly and, when applicable, in accordance with the product label.  For non-product 
methods (e.g.  male sterility), the investigator determines what is consistent and correct 
use. The GSK definition is based on the definition provided by the ICH [ICH, M3 (R2) 
2009].
The investigator is responsible for ensuring that subjects understand how to properly use 
these methods of contraception.
13.6.1.
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 5. 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

Protocol Amendment 01
This protocol amendment has been created to include an additional exercise challenge 
procedure at 23 hours after the first dose of double-blinded study medication in each 
Treatment Period. The purpose is to demonstrate that inhaled FF/VI 100/25 mcg provides 
improved bronchoprotection against EIB compared with FP 250 mcg after 23 hours of 
treatment with blinded medication. In addition, it will allow for an evaluation of the 
presence and extent of tachyphylaxis.
The study title has been revised to indicate the study is a randomised study with a 
crossover design.
Other minor corrections and edits have been made.

Protocol Synopsis: Overall Design
Original text:
This is a multicenter, randomized, double-blind, double-dummy, crossover study with 
two 2-week treatment periods separated by a 2-week wash-out period. Subjects will 
attend five evening visits over the course of the study. Standardized exercise challenge 
testing will be conducted at Visit 2 for eligibility determination, and at 12 and 23 hours 
post evening dose at Visits 3 and 5. Spirometry will be conducted at Screening (Visit 1),

and pre-dose at Visit 4, and prior to each exercise challenge at Visits 2, 3 and 5. Serial 
spirometry (6 time points over 60 minutes) as FEV1 only will be conducted after each 
exercise challenge test. Subjects should be monitored until they reach a recovery level 
where their FEV1 value represents a 95% recovery of the pre-exercise FEV1 result.  
Additional spirometry and rescue medication may be used as needed during recovery.
A Pre-Screening Visit (Visit 0) is included to obtain a signed Informed Consent and to 
review concomitant medications, and may be conducted on the same day as Visit 1, if 
appropriate. At Visit 1, subjects meeting eligibility criteria and will enter a 4 week single-
blinded run-in period on fluticasone propionate (FP) 250 mcg twice daily (BD). 
Albuterol/salbutamol will be issued for rescue use during the run-in, wash-out and 
treatment periods as needed.  Subjects will be instructed to contact the site if they develop 
worsening asthma.  
A screening electrocardiogram (ECG) and a complete physical examination will be 
conducted at Visit 1. Vital signs will be collected at each visit prior to spirometry and 
before and after each exercise challenge.
Physical activity levels will be monitored with the use of a physical activity monitor to 
assess activity outside the clinic worn for 7 days prior to Visit 2 (baseline), for 7 days 
during the last week of Treatment Period 1, for 7 days prior to Visit 4, and for 7 days 
during the last week of Treatment Period 2. Subjects unwilling or unable to participate in 
daily physical activity monitoring may still participate in the study, if appropriate.
Asthma control will be assessed using the Asthma Control Test at Visits 2 through 5. 
A follow up phone call will be conducted approximately 7 days after Visit 5.

duration)
Section 5.1: Overall Design
Original text:
This is a multicenter, randomized, double-blind, double-dummy, crossover study with 
two 2-week treatment periods separated by a 2-week wash-out period. Subjects will 
attend five evening visits over the course of the study. Standardized exercise challenge 
testing will be conducted at Visit 2 for eligibility determination, and at 12 and 23 hours 
post evening dose at Visits 3 and 5. Spirometry will be conducted at Screening (Visit 1), 
and pre-dose at Visit 4, and prior to each exercise challenge at Visits 2, 3 and 5. Serial 
spirometry (6 time points over 60 minutes) as FEV1 only will be conducted after each 
exercise challenge test. Subjects should be monitored until they reach a recovery level 
where their FEV1 value represents a 95% recovery of the pre-exercise FEV1 result.  
Additional spirometry and rescue medication may be used as needed during recovery.

A Pre-Screening Visit (Visit 0) is included to obtain a signed Informed Consent (ICF) 
and to review concomitant medications, and may be conducted on the same day as Visit 
1, if appropriate. At Visit 1, subjects meeting eligibility criteria will enter a 4-week 
single-blinded run-in period on fluticasone propionate (FP) 250 mcg twice daily (BD). 
Albuterol will be issued for rescue use during the run-in, wash-out and treatment periods 
as needed.  Subjects will be instructed to contact the site if they develop worsening 
asthma.  
All subjects will be given a paper diary during the run-in, washout and treatment periods 
to record any medical problems experienced during the study, any medications taken, and 
rescue medication usage.
A screening electrocardiogram (ECG) and a complete physical examination will be 
conducted at Visit 1. Vital signs will be collected at each visit prior to spirometry, and 
before and after exercise challenge testing.  
Asthma control will be assessed using the Asthma Control Test (ACT) at Visits 2 through 
5.
Physical activity levels will be monitored to assess activity outside the clinic [Mitchell, 
2014] using a physical activity monitor (SenseWear Armband accelerometer) worn for 7 
days prior to Visit 2 (baseline), for 7 days prior to Visit 3 (during the last week of 
Treatment Period 1), for 7 days prior to Visit 4, and for 7 days prior to Visit 5 (during the 
last week of Treatment Period 2). Subjects unwilling or unable to participate in daily 
physical activity monitoring may still participate in the study, if appropriate. See Study 
Reference Manual (SRM) for additional details.
A follow up phone call will be conducted approximately 7 days after Visit 5.

Section 7.8: Treatment after the End of the Study
Original text:
Subjects will not receive any additional treatment from GSK after completion of the 
study as other treatment options are available for persistent asthma. 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. At the end of Visit 5, investigators should prescribe asthma medication 
appropriate to the severity of the subject’s asthma in accordance with asthma guidelines 
[GINA, 2015; NIH, 2007]. Do not record asthma medications started on or after the final 
clinic visit in the eCRF.

A clinically validated physical activity monitor (accelerometer) will be used to measure 
specific levels of physical activity. There will be 4 assessment periods, including an 
initial baseline assessment in order to provide a reliable estimate of habitual physical 
activity. The physical activity monitor will be worn by the study subjects during the 
weeks prior to Visit 2, Visit 3, Visit 4 and Visit 5. Further details will be provided in the 
SRM.
Subjects will be contacted by telephone 8-9 days prior to Visits 2, 3, 4 and 5 and 
reminded to wear the SenseWear Armband accelerometer for the 7 days preceeding these 
visits.

1.
Test at the 5% level the null hypothesis that the true population difference 
between the treatment group means in maximal percent decrease in FEV1 from 
pre-exercise at 23 hrs post-dose is zero.
2.
If 1 is significant then test at the 5% level the null hypothesis that the true 
probability distributions for the treatment groups for not recovering to within 5% 
of pre-exercise FEV1 at 12 hrs post-dose (i.e. the “survival” distributions for the 
endpoint time to recovery to within 5% of pre-exercise FEV1 at 12 hrs post-dose) 
are equal.

population probability distributions for the treatment groups for not recovering to 
within 5% of pre-exercise FEV1 at 23 hrs post-dose (i.e. the “survival” 
distributions for the endpoint time to recovery to within 5% of pre-exercise FEV1
at 23 hrs post-dose) are equal.
4.
If 3 is significant then test at the 5% level the null hypothesis that the true 
population difference between the treatment group means in AUC for percentage 
decrease in FEV1 from pre-exercise FEV1 at 12 hrs post-dose is zero.
5.

Test at the 5% level the null hypothesis that the true population difference 
between the treatment group means in maximal percent decrease in FEV1 from 
pre-exercise at 23 hrs post-dose at the end of the 2-week treatment period is 
zero.
2.
If 1 is significant then test at the 5% level the null hypothesis that the true 
probability distributions for the treatment groups for not recovering to within 5% 
of pre-exercise FEV1 at 12 hrs post-dose at the end of the 2-week treatment 
period (i.e. the “survival” distributions for the endpoint time to recovery to within 
5% of pre-exercise FEV1 at 12 hrs post-dose) are equal.
3.
If 2 is significant then test at the 5% level the null hypothesis that the true 
population probability distributions for the treatment groups for not recovering to 
within 5% of pre-exercise FEV1 at 23 hrs post-dose at the end of the 2-week 
treatment period (i.e. the “survival” distributions for the endpoint time to 
recovery to within 5% of pre-exercise FEV1 at 23 hrs post-dose) are equal.

If 3 is significant then test at the 5% level the null hypothesis that the true 
population difference between the treatment group means in AUC for percentage 
decrease in FEV1 from pre-exercise FEV1 at 12 hrs post-dose at the end of the 2-
week treatment period is zero.

For the primary efficacy endpoint of maximal percent decrease in FEV1 following 
exercise challenge at 12 hours post-dose, given an assumed 10% screen failure rate, a 
55% run-in failure rate, and a 15% withdrawal rate post-randomisation, a total of 
approximately 165 subjects will be screened. Given these assumed failure and withdrawal 
rates we expect 148 subjects will enter the run-in period, of which 66 subjects will be 
randomized, of which 56 subjects will be evaluable, that is completing the exercise 
challenges and the FEV1 evaluations at the end of both treatment periods. With 56 
evaluable subjects this study has approximately 90% power assuming a true population 
difference of 5% in maximal percent decrease in FEV1 between the two treatment groups.  
This assumes a within-subject standard deviation (SD) of 8% where significance is 
declared at the two-sided 5% significance level.

Protocol Amendment 02
This amendment applies to all trial centres participating in study 201832.
This protocol is being amended to make the following changes:

Increase the screen failure rate to 20% (from 10%) and the run-in failure rate to 70% 
(from 55%). This takes into consideration the challenge of enrolling EIB subjects 
with symptomatic allergic rhinitis (SAR) at screening and also the challenge for 
subjects to demonstrate a decrease in FEV1 of ≥20% at one time point within 30 
minutes of the end of the exercise challenge at Visit 2; after taking fluticasone 
propionate for approximately four weeks during the run-in period. 

Allow subjects with symptomatic allergic rhinitis at screening to be treated for up to 
four weeks with intranasal corticosteroids followed by a repeat screening visit to 
determine eligibility prior to entry into the study. Subjects that continue to be 
symptomatic after up to four weeks of treatment will be excluded. Eligible subjects 
will enter the run-in phase for 4 weeks on FP before the first exercise challenge at
Visit 2.

Allow subjects who are asymptomatic at screening, who become symptomatic during 
the study to remain in the study and be treated with intranasal corticosteroids at a 
constant dose for the duration of the study. Therefore, the randomisation exclusion 
criterion 6 (symptomatic allergic rhinitis) has been deleted. 

Include tobacco/marijuana use and pregnancy (which were omitted in error in the 
original protocol) as exclusion criteria.

Clarify the expectations for subjects for Visits 4 and 7 with regards to the number of 
anticipated clinic visits (and procedures) over the 24-hour period for both visits.

Extend the time window for the repeat exercise challenge from 24-48 hours to up to 
one week; taking into consideration the challenge for subjects to return within 48 
hours for a repeat procedure.

Replace the ACT questionnaire with the ACQ-5 questionnaire, given the mismatch 
between treatment periods of two weeks and the recall period of 4 weeks for the 

2015N231308_03
CONFIDENTIAL
201832
117
ACT.  ACT will not clearly represent asthma control for the specific treatment 
periods.

Increase the restriction period for caffeinated beverages to 4 hours prior to 
spirometry and the exercise challenge procedure (previously 2 hours prior to 
spirometry) due to the possibility of inducing refractoriness. 

The time to recovery endpoint (time to recovery to within 5% of pre-exercise FEV1
as measured from the time of maximal decline in post-exercise FEV1) has been 
changed to a binary endpoint defining recovery as those subjects who have a 30 
minute post-exercise FEV1 measurement that is no more than 5% lower than their 
pre-exercise FEV1. This binary endpoint has also been included in the “other 
endpoints” at all the remaining post-exercise spirometry time points.

The statistical testing hierarchy has been changed to prioritise the maximal 
percentage FEV1 reduction (primary endpoint) and binary recovery endpoints 
following the 12 hour post-dose exercise challenge.

Other edits and minor corrections have been made.

Protocol Synopsis: Overall Design
Original text:
This is a multicenter, randomized, double-blind, double-dummy, crossover study with 
two 2-week treatment periods separated by a 2-week wash-out period. Subjects will 
attend up to eight visits over the course of the study. Standardized exercise challenge 
testing will be conducted at Visit 2 for eligibility determination, Visit 3 and Visit 6 (after 
23 hours of the first treatment dose in each Treatment Period); and at 12 and 23 hours 
post evening dose at Visits 4 and 7. Spirometry will be conducted at Screening (Visit 1), 
and pre-dose at Visit 5, and prior to each exercise challenge at Visits 2, 3, 4, 6 and 7. 
Serial spirometry (6 time points over 60 minutes) as FEV1 only will be conducted after 
each exercise challenge test. Subjects should be monitored until they reach a recovery 
level where their FEV1 value represents a 95% recovery of the pre-exercise FEV1 result.  
Additional spirometry and rescue medication may be used as needed during recovery.
A Pre-Screening Visit (Visit 0) is included to obtain a signed Informed Consent and to 
review concomitant medications, and may be conducted on the same day as Visit 1, if 
appropriate. At Visit 1, subjects meeting eligibility criteria and will enter a 4 week single-
blinded run-in period on fluticasone propionate (FP) 250 mcg twice daily (BD). 
Albuterol will be issued for rescue use during the run-in, wash-out and treatment periods 
as needed.  Subjects will be instructed to contact the site if they develop worsening 
asthma.  
A screening electrocardiogram (ECG) and a complete physical examination will be 
conducted at Visit 1. Vital signs will be collected at each visit prior to spirometry and 
before and after each exercise challenge.
Physical activity levels will be monitored with the use of a physical activity monitor to 
assess activity outside the clinic worn for 7 days prior to Visit 2 (baseline), for 7 days 
during the last week of Treatment Period 1, for 7 days prior to Visit 5, and for 7 days 
during the last week of Treatment Period 2. Subjects unwilling or unable to participate in 
daily physical activity monitoring may still participate in the study, if appropriate.

Asthma control will be assessed using the Asthma Control Test at Visits 2, 4, 5 and 7. 
A follow up phone call will be conducted approximately 7 days after Visit 7.
Revised text:
This is a multicenter, randomized, double-blind, double-dummy, crossover study with 
two 2-week treatment periods separated by a 2-week wash-out period. Subjects will
participate in up to eight study visits (Visit 0 to Visit 7) over the course of the study 
and a follow up phone call approximately a week after Visit 7. Visits 1, 2, 3, 5 and 6 
are evening visits that will be conducted between 5PM and 11PM. Visit 4 and Visit 7 
are also evening visits that will begin between 5PM and 11PM and continue over a 
period of approximately 24 hours. Subjects will be required to attend three clinic 
visits during this 24-hour period.
Standardized exercise challenge testing (using a treadmill) will be conducted at Visit 2 
for eligibility determination, Visit 3 and Visit 6 (after 23 hours of the first treatment dose 
in each Treatment Period); and at 12 and 23 hours post evening dose at Visits 4 and 7. 
Spirometry will be conducted at Screening (Visit 1), and pre-dose at Visit 5, and prior to 
each exercise challenge at Visits 2, 3, 4, 6 and 7. Serial spirometry (6 time points over 60 
minutes) as FEV1 only will be conducted after each exercise challenge test. At Visit 2, 
subjects must demonstrate a decrease in FEV1 of ≥20% when compared to the FEV1
obtained immediately pre-exercise for at least one of the post-exercise spirometry 
efforts obtained within 30 minutes post-challenge.  Subjects who achieve a decrease 
in FEV1 of 15% to <20% may continue taking their daily run-in medication and 
repeat the eligibility exercise challenge and associated procedures once within a 
week of the original procedure. Subjects should be monitored until they reach a 
recovery level where their FEV1 value represents a 95% recovery of the pre-exercise 
FEV1 result.  Additional spirometry and rescue medication may be used as needed during 
recovery.
A Pre-Screening Visit (Visit 0) is included to obtain a signed Informed Consent, 
demography and to review concomitant medications, and may be conducted on the same 
day as Visit 1, if appropriate. 
At Visit 1, subjects meeting eligibility criteria and will enter a 4 week single-blinded run-
in period on fluticasone propionate (FP) 250 mcg twice daily (BD). Subjects with 
symptomatic allergic rhinitis at Visit 1 (screening) may be treated for up to four 
weeks with intranasal corticosteroids followed by a repeat screening visit to 
determine eligibility prior to entry into the study. Only one repeat screening visit 
will be performed following treatment with intranasal corticosteroids. Subjects that 
continue to be symptomatic after up to four weeks of treatment will be excluded. 
Eligible subjects will enter the run-in period. Subjects who are asymptomatic at 
screening, who become symptomatic during the study will remain in the study and 
may be treated with intranasal corticosteroids at a constant dose for the duration of 
the study.

Albuterol/salbutamol will be issued for rescue use during the run-in, wash-out and 
treatment periods as needed.  Subjects will be instructed to contact the site if they develop 
worsening asthma.  
All subjects will be given a paper diary during the run-in, washout and treatment 
periods to record any medical problems experienced during the study, any 
medications taken, and rescue medication usage.
A screening electrocardiogram (ECG) and a complete physical examination will be 
conducted at Visit 1. Vital signs including pulse rate and systolic and diastolic blood 
pressure will be obtained at each clinic visit, including any Early Withdrawal visit. 
At all time points where both vital signs and spirometry are performed, vital signs 
will be done before the spriometry measurement. At visits where the exercise 
challenge is performed, vitals will be measured before (prior to the pre-exercise 
spirometry) and after the exercise challenge.
Asthma control will be assessed using the ACQ-5 at Visits 2, 4, 5 and 7. 
Physical activity levels will be monitored to assess activity outside the clinic with the 
use of a physical activity monitor (SenseWear Armband accelerometer) worn for 7 
days prior to Visit 2 (baseline), for 7 days prior to Visit 4 (during the last week of 
Treatment Period 1), for 7 days prior to Visit 5, and for 7 days prior to Visit 7 (during 
the last week of Treatment Period 2). Subjects unwilling or unable to participate in daily 
physical activity monitoring may still participate in the study, if appropriate.
A follow up phone call will be conducted approximately 7 days after Visit 7.
Section 2.2: Study rationale
Original text:
In patients with persistent asthma, improvements in protection from exercise-induced 
bronchoconstriction (EIB) with ICS/LABA combination product FP/salmeterol 
(Advair®) have been demonstrated [Murray, 2011; Pearlman, 2009; Weiler, 2005]. 
However, differences between FP/salmeterol and FP monotherapy have not consistently 
been observed [Murray, 2011; Weiler, 2005]. In a study that evaluated the effect of 
FP/salmeterol compared to FP over the 12 hour dosing interval [Weiler, 2005], a large 
percentage of subjects in both the FP/salmeterol (18%) and FP (36% and 33% at Day 1 
and Week 4, respectively) treatment arms failed to complete the second exercise 
challenge test 8.5 hours after dosing, suggesting loss of protection against EIB towards
the end of the 12 hour dosing interval

dose at Visits 4 and 7. Spirometry will be conducted at Screening (Visit 1), and pre-dose 
at Visit 5 and prior to each exercise challenge at Visits 2, 3, 4, 6 and 7. Serial spirometry 
(6 time points over 60 minutes) as FEV1 only will be conducted after each exercise 
challenge test. Subjects should be monitored until they reach a recovery level where their 
FEV1 value represents a 95% recovery of the pre-exercise FEV1 result.  Additional 
spirometry and rescue medication may be used as needed during recovery.
A Pre-Screening Visit (Visit 0) is included to obtain a signed Informed Consent (ICF) 
and to review concomitant medications, and may be conducted on the same day as Visit 
1, if appropriate. At Visit 1, subjects meeting eligibility criteria will enter a 4-week 
single-blinded run-in period on fluticasone propionate (FP) 250 mcg twice daily (BD). 
Albuterol will be issued for rescue use during the run-in, wash-out and treatment periods 
as needed.  Subjects will be instructed to contact the site if they develop worsening 
asthma.  
All subjects will be given a paper diary during the run-in, washout and treatment periods 
to record any medical problems experienced during the study, any medications taken, and 
rescue medication usage.
A screening electrocardiogram (ECG) and a complete physical examination will be 
conducted at Visit 1. Vital signs will be collected at each visit prior to spirometry, and 
before and after exercise challenge testing.

Asthma control will be assessed using the Asthma Control Test (ACT) at Visits 2, 4, 5 
and 7.
Physical activity levels will be monitored to assess activity outside the clinic [Mitchell, 
2014] using a physical activity monitor (SenseWear Armband accelerometer) worn for 7 
days prior to Visit 2 (baseline), for 7 days prior to Visit 4 (during the last week of 
Treatment Period 1), for 7 days prior to Visit 5, and for 7 days prior to Visit 7 (during the 
last week of Treatment Period 2). Subjects unwilling or unable to participate in daily 
physical activity monitoring may still participate in the study, if appropriate. See Study 
Reference Manual (SRM) for additional details.
A follow up phone call will be conducted approximately 7 days after Visit 7.
For determination of subject disposition, subjects will be considered to have completed 
the study upon completion of Visit 7. For entry into the electronic case report form 
(eCRF), study completion will be defined as completion of the follow up contact.
There are no plans to routinely provide any of the study treatments for compassionate use 
following study completion, as asthma treatments including ICS/LABA combination 
products are available worldwide.
Supplementary study conduct information not mandated to be present in this protocol is 
provided in the SRM. The SRM will provide the site personnel with administrative and 
detailed technical information that does not impact subject safety.
Revised text:
This is a multicenter, randomized, double-blind, double-dummy, crossover study with 
two 2-week treatment periods separated by a 2-week wash-out period. Subjects will
participate in up to eight study visits (Visit 0 to Visit 7) over the course of the study
and a follow up phone call approximately a week after Visit 7. Visits 1, 2, 3, 5 and 6 
are evening visits that will be conducted between 5PM and 11PM. Visit 4 and Visit 7 
are also evening visits that will begin between 5PM and 11PM and continue over a 
period of approximately 24 hours. Subjects will be required to attend three clinic 
visits during this 24-hour period.
Standardized exercise challenge testing (using a treadmill) will be conducted at Visit 2 
for eligibility determination, Visit 3 and Visit 6 (after 23 hours of the first dose in each 
Treatment Period); and at 12 and 23 hours post evening dose at Visits 4 and 7. 
Spirometry will be conducted at Screening (Visit 1), and pre-dose at Visit 5 and prior to 
each exercise challenge at Visits 2, 3, 4, 6 and 7. Serial spirometry (6 time points over 60 
minutes) as FEV1 only will be conducted after each exercise challenge test. At Visit 2, 
subjects must demonstrate a decrease in FEV1 of ≥20% when compared to the FEV1
obtained immediately pre-exercise for at least one of the post-exercise spirometry 
efforts obtained within 30 minutes post-challenge.  Subjects who achieve a decrease 
in FEV1 of 15% to <20% may continue taking their daily run-in medication and

repeat the eligibility exercise challenge and associated procedures once within a 
week of the original procedure. Subjects should be monitored until they reach a 
recovery level where their FEV1 value represents a 95% recovery of the pre-exercise 
FEV1 result.  Additional spirometry and rescue medication may be used as needed during 
recovery. 
A Pre-Screening Visit (Visit 0) is included to obtain a signed Informed Consent (ICF), 
demography and to review concomitant medications, and may be conducted on the same 
day as Visit 1, if appropriate. 
At Visit 1, subjects meeting eligibility criteria will enter a 4-week single-blinded run-in 
period on fluticasone propionate (FP) 250 mcg twice daily (BD). Subjects with 
symptomatic allergic rhinitis at Visit 1 (screening) may be treated for up to four 
weeks with intranasal corticosteroids followed by a repeat screening visit to 
determine eligibility prior to entry into the study. Only one repeat screening visit 
will be performed following treatment with intranasal corticosteroids. Subjects that 
continue to be symptomatic after up to four weeks of treatment will be excluded. 
Eligible subjects will enter the run-in period. Subjects who are asymptomatic at 
screening, who become symptomatic during the study will remain in the study and 
may be treated with intranasal corticosteroids at a constant dose for the duration of 
the study.
Albuterol/salbutamol will be issued for rescue use during the run-in, wash-out and 
treatment periods as needed.  Subjects will be instructed to contact the site if they develop 
worsening asthma.

All subjects will be given a paper diary during the run-in, washout and treatment periods 
to record any medical problems experienced during the study, any medications taken, and 
rescue medication usage.
A screening electrocardiogram (ECG) and a complete physical examination will be 
conducted at Visit 1. Vital signs including pulse rate and systolic and diastolic blood 
pressure will be obtained at each clinic visit, including any Early Withdrawal visit. 
At all time points where both vital signs and spirometry are performed, vital signs 
will be done before the spriometry measurement. At visits where the exercise 
challenge is performed, vitals will be measured before (prior to the pre-exercise 
spirometry) and after the exercise challenge.
Asthma control will be assessed using the ACQ-5 at Visits 2, 4, 5 and 7.
Physical activity levels will be monitored to assess activity outside the clinic [Mitchell, 
2014] using a physical activity monitor (SenseWear Armband accelerometer) worn for 7 
days prior to Visit 2 (baseline), for 7 days prior to Visit 4 (during the last week of

last week of Treatment Period 2). Subjects unwilling or unable to participate in daily 
physical activity monitoring may still participate in the study, if appropriate. See Study 
Reference Manual (SRM) for additional details.
A follow up phone call will be conducted approximately 7 days after Visit 7.
Re-screening of subjects is not allowed in this study with the exception of subjects 
with symptomatic allergic rhinitis at screening who may have a repeat screening 
visit after treatment with intranasal corticosteroids.

Original text:
The following non-asthma medications are permitted. This list is not all inclusive. For 
any questions contact the Medical Monitor.

Cardioselective beta-blockers (stable dose) and ophthalmic beta-blockers: 
Administer with caution as they may block bronchodilatory effects of beta-agonists 
and produce severe bronchospasm.

Strong cytochrome P450 3A4 inhibitors (e.g. ketoconazole, ritonavir, 
clarithromycin): Use with caution. May cause systemic corticosteroid and 
cardiovascular effects.

Tricyclic antidepressants and monoamine oxidase inhibitors (MAOIs):
Administer with extreme caution as they may potentiate the effects of beta-
agonists on the vascular system.

Diuretics: Caution is advised in the co-administration of beta-agonists with non 
potassium–sparing diuretics.

Decongestants: Subjects may take decongestants during the study except during the 
24 hours prior to ECG measurements.

Antihistamines: Short-acting and long-acting antihistamines are allowed to control 
symptoms of allergic disorders, however are not permitted the week prior to 
exercise testing. In addition, antihistamine eye drops are allowed during the study. 

Intranasal corticosteroids: Subjects may take intranasal corticosteroids to control 
symptoms of allergic disorders as long as the dose remains constant for the duration 
of the study.

Topical corticosteroids: Subjects may use topical corticosteroids (≤ 1% 
hydrocortisone) for dermatological diseases.

Section 8.3.1: Spirometry
Original text:
Subjects will be required to withhold their rescue medication (albuterol) for at least 6 
hours before each visit. 
Exercise challenges should not be performed within 24 hours of exercise in cold air. 
Subjects should abstain from smoking or drinking beverages with high caffeine content 
such as tea or coffee for 2 hours prior to pulmonary function testing. 
The FEV1 should be measured using spirometry equipment that meets or exceeds the 
minimal recommendations of the American Thoracic Society (ATS)/European 
Respiratory Society (ERS) [Miller, 2005]. All sites will use standardized spirometry 
equipment provided by an external vendor. 
FEV1 and FVC will be conducted at Visit 1, and pre-dose at Visit 5, and prior to each 
exercise challenge at Visits 2, 3, 4, 6 and 7. For full FEV1/FVC testing, at least 3 valid 
and 2 repeatable (with no more than 8) efforts should be obtained using ATS/ERS 
guidelines. At each time point, the largest FEV1 and FVC should be recorded, even if 
they do not come from the same effort. 
Serial FEV1 measurements only (not FVC) will be conducted serially as described in 
Table 3 following each exercise challenge at Visits 2, 3, 4, 6 and 7. For serial FEV1
testing, two FEV1 efforts will be obtained at each time point. At each time point, the 
largest FEV1 will be selected.

For full FEV1 and FVC testing at Screening and at randomisation (Visit 2), at least two
valid and two repeatable (with no more than 8) efforts should be obtained using 
ATS/ERS guidelines. For all other visits where full FEV1 and FVC testing is performed 
(prior to each exercise test at visits 3, 4, 6 and 7), at least two valid efforts should be 
obtained.  At each time point, the largest FEV1 and FVC should be recorded, even if they 
do not come from the same effort. 
Serial FEV1 measurements only (not FVC) will be conducted serially as described in 
Table 3 following each exercise challenge at Visits 2, 3, 4, 6 and 7. 
Subjects must have a FEV1 of at least 70% of their predicted normal value to be 
eligible to take part in the study at Visit 1.
After Visit 1, subjects will always be required to withhold their albuterol/salbutamol 
for at least 6 hours before each clinic visit.
Subjects must not administer study drug prior to coming to the clinic on study visit 
days.
Section 8.3.2: Exercise Challenge Testing
Original text:
The exercise challenge test is a stepped challenge on a treadmill at a speed and incline 
that will allow the subject’s heart rate to reach between 80% to 95% of their maximum 
heart rate. All exercise challenges will be performed on a treadmill. During the exercise 
challenge, subjects will breathe medical grade dry air at ambient temperature from a 
reservoir using a two-way non-rebreathing valve.
Subjects will exercise sufficiently to attain a heart rate between 80 to 95% of their 
predicted maximum within 4 minutes and maintain this heart rate with exercise for an 
additional 6 minutes for a total of 10 minutes of exercise. The challenge will be followed 
immediately by serial spirometry (FEV1 efforts only) at 6 time points over 60 minutes (5, 
10, 15, 30, 45 and 60 minutes post-exercise). The information gained from the eligibility 
challenge(s) regarding incline and speed will be used to obtain the target heart rate in the 
subsequent exercise challenges.
Additional instructions on exercise challenge testing can be found in the SRM.

Section 8.3.5: Asthma Control Test (ACT) 
Original text:
The ACT is a five-item questionnaire developed as a measure of subjects’ asthma control 
that can be quickly and easily completed in clinical practice. The questions are designed 
to be self-completed by the subject. It is recommended that the ACT be administered at 
the same time during each visit. To avoid biasing responses, the subjects should not be 
told the results of diagnostic tests prior to completing the questionnaire and should be 
completed before any procedures are performed on the subject to avoid influencing the 
subject’s response. Adequate time should be allowed to complete all items on the ACT.
The subject should be given a quiet area in which to complete the questionnaire.
The investigator should ask the subject to complete the questions as accurately as 
possible. If the subject requests help or clarification with any of the questions, he/she will 
be asked to re-read the instructions and give the answer that best reflects how he/she felt 
over the previous 4 weeks. The subject should be reassured that there are no right or 
wrong answers. The investigator should not provide the subject with any answer or 
attempt to interpret any portion of a question.

Asthma Control Questionnaire-5 (ACQ-5) (New text)
The ACQ-5 will be completed at the beginning of all study visits where the form is 
completed. 
The ACQ-5 is a five-item questionnaire, which has been developed as a measure of 
subject’ asthma control that can be quickly and easily completed [Juniper, 2005].
The questions are designed to be self-completed by the subject. The five questions 
enquire about the frequency and/or severity of symptoms (nocturnal awakening on 
waking in the morning, activity limitation, and shortness of breath, wheeze). The 
response options for all these questions consist of a zero (no impairment/limitation) 
to six (total impairment/ limitation) scale.
The subject should be given a quiet area in which to complete the questionnaire. 
The investigator should ask the subject to complete the questions as accurately as 
possible. If the subject requests help or clarification with any of the questions, 
he/she will be asked to re-read the instructions and give the answer that best reflects 
how he/she felt over the previous week. The subject should be reassured that there 
are no right or wrong answers. The investigator should not provide the subject with 
any answer or attempt to interpret any portion of a question.
It is recommended that the ACQ-5 be administered at the same time during each 
visit. To avoid biasing responses, the subjects should not be told the results of 
diagnostic tests prior to completing the questionnaire and should be completed

Section 10.1: Hypotheses
Original text:
The primary endpoint is the maximal percent decrease in FEV1 following exercise 
challenge at 12-hours post-dose at the end of the 2-week treatment period.  
The treatment comparison is the FF/VI combination versus FP.  Demonstration of 
efficacy for this treatment comparison will be based on a hypothesis testing approach 
whereby the null hypothesis is that there is no difference between treatment groups and 
the alternative hypothesis is that there is a difference between treatment groups.  
A 2-sided 5% probability associated with incorrectly rejecting the null hypothesis 
(significance level) is considered acceptable for this study. In order to account for 
multiplicity, this primary hypothesis test on the primary endpoint for the ITT (Intent-to-
Treat) population will act as a gatekeeper for all other hypothesis tests using the 
secondary endpoints, where these tests will proceed in a pre-defined order.
If the primary hypothesis on the primary endpoint for the ITT population is rejected then 
the following hierarchy of tests will be performed using the ITT population; 
1.
Test at the 5% level the null hypothesis that the true population difference 
between the treatment group means in maximal percent decrease in FEV1 from 
pre-exercise at 23 hrs post-dose at the end of the 2-week treatment period is zero.
2.
If 1 is significant then test at the 5% level the null hypothesis that the true 
probability distributions for the treatment groups for not recovering to within 5% 
of pre-exercise FEV1 at 12 hrs post-dose at the end of the 2-week treatment 
period (i.e. the “survival” distributions for the endpoint time to recovery to within 
5% of pre-exercise FEV1 at 12 hrs post-dose) are equal.
3.
If 2 is significant then test at the 5% level the null hypothesis that the true 
population probability distributions for the treatment groups for not recovering to 
within 5% of pre-exercise FEV1 at 23 hrs post-dose at the end of the 2-week 
treatment period (i.e. the “survival” distributions for the endpoint time to recovery 
to within 5% of pre-exercise FEV1 at 23 hrs post-dose) are equal.
4.
If 3 is significant then test at the 5% level the null hypothesis that the true 
population difference between the treatment group means in AUC for percentage 
decrease in FEV1 from pre-exercise FEV1 at 12 hrs post-dose at the end of the 2-
week treatment period is zero.
5.
If 4 is significant then test at the 5% level the null hypothesis that the true 
population difference between the treatment group means in AUC for percentage 
decrease in FEV1 from pre-exercise FEV1 at 23 hrs post-dose at the end of the 2-
week treatment period is zero.

Section 10.2.1: Sample Size Assumptions
Original text:
For the primary efficacy endpoint of maximal percent decrease in FEV1 following 
exercise challenge at 12 hours post-dose at the end of the 2-week treatment period, given 
an assumed 10% screen failure rate, a 55% run-in failure rate, and a 15% withdrawal rate 
post-randomisation, a total of approximately 165 subjects will be screened. Given these 
assumed failure and withdrawal rates we expect 148 subjects will enter the run-in period, 
of which 66 subjects will be randomized, of which 56 subjects will be evaluable, that is 
completing the exercise challenges and the FEV1 evaluations at the end of both treatment 
periods. With 56 evaluable subjects this study has approximately 90% power assuming a 
true population difference of 5% in maximal percent decrease in FEV1 between the two 
treatment groups.  This assumes a within-subject standard deviation (SD) of 8% where 
significance is declared at the two-sided 5% significance level. 
Subjects will be centrally randomized to one of the two treatment sequences shown 
below in Table 4 in a 1:1 ratio:

Original text:
Summaries and analyses for secondary endpoints will be provided for the ITT population.  
Maximal percent decrease from pre-exercise FEV1 following exercise challenge (at 23 
hours post-dose at the end of the 2-week treatment period):
This endpoint will be summarized and analyzed as for the primary endpoint of maximal 
percent decrease from pre-exercise FEV1 following exercise challenge at 12 hours post-
dose.  
Time required for recovery to within 5% of the pre-exercise FEV1 from the time of the 
maximal percentage decrease from pre-exercise FEV1 following the challenge (at 12 
hours and 23 hours post-dose at the end of the 2-week treatment period):
The time required for recovery to within 5% of the pre-exercise FEV1 from the time of 
the maximal percentage decrease from pre-exercise FEV1 following exercise challenge at 
12 hours and 23 hours post-dose for both treatment groups will be compared using a log-
rank test. The log rank test will test the null hypotheses that the survival distributions of 
the two treatment groups are equal. In addition the estimated hazard ratio, confidence 
interval and p-value will be presented. Kaplan-Meier plots showing the cumulative 
incidence curves for each treatment group will be produced. 
AUC (0-60 min) for percentage decrease from pre-exercise FEV1 after exercise (at 12 
hours and 23 hours post-dose at the end of the 2-week treatment period):
A comparison will be made of the estimated means of the two treatment groups in AUC 
of the percentage decrease in FEV1 from pre-exercise at 12 and 23 hrs post-dose using a 
LMM to adjust for covariate effects. The LMM will include the following covariates: 
treatment, subject-level mean of the pre-treatment FEV1 period baselines (mean of the 2 
period baselines per subject), centered period-level baseline FEV1 (period baselines 
centered using subject-level mean of the pre-treatment FEV1 period baselines),  gender, 
age, treatment period and smoking history as fixed effects, and a random intercept for 
each subject.
