SUMMARY OF CHANGES TO PT010006-01 VERSION 2.0, 
DATED 04 MAY 2016 
Section(s)/Description of Change 
Rationale 
Synopsis, Section 2.2/Secondary Objectives, 
and Section 3.2/Secondary Efficacy 
Endpoints 
Added rate of moderate or severe COPD 
exacerbations. 
Added time to Clinically Important 
Deterioration (CID)-except for the US 
approach 
Exacerbations are an important endpoint and 
there is sufficient sample size to observe at 
least a numerical benefit in the form of a 
trend, even though the study is not optimized 
to demonstrate statistical significance. 
Time to CID encompasses lung function, 
symptomatic benefit, and exacerbations into 
a single endpoint. 
Section 2.3/Other Efficacy Objective 
Removed the rate of moderate or severe 
COPD exacerbations. 
Added time to sustained CID. 
Added time to CID (since not included as a 
secondary endpoint in US approach). 
The rate of moderate or severe exacerbations 
is now a secondary objective.  
Synopsis and Study Endpoint Sections 3, 
3.2.1, 3.2.2, 3.2.3, 3.3.1, 3.3.2, 3.4, 3.5, 3.6.1, 
3.6.2, 3.6.3.2, and 9.1. 
Added the following sentence to Section 3 
“Study Endpoints”, Section 9.1 and 
Synopsis: Countries not specifically 
mentioned will be decided by regulatory 
requirements and included in one of the three 
defined registration approaches. 
Addition of US endpoints 
The EXACT Total Score which was a 
secondary endpoint is now an Other 
endpoint. The E-RS:COPD RS-Total Score, 
which was an other endpoint, is instead a 
secondary endpoint in place of the EXACT 
Total Score for the EU/CAN approach. 
Added sentence to clarify the registration 
approach for countries that are not 
specifically mentioned. 
Added US endpoints to support registration 
in the US and other markets that use similar 
endpoints. 
The E-RS:COPD RS-Total score is more 
aligned with the population included in this 
study. The EXACT total is more appropriate 
for an exacerbation study. 
Though underpowered, analyses of severe 
COPD exacerbations will be conducted as 
well due to their clinical relevance. 
A table is needed to support the plot of FEV1 
over time in the 12-hr PFT sub-study. 
AUC0-4 is assessed in subjects outside of the

Severe COPD exacerbations were added 
Clarification of the endpoints for the 12-hr 
PFT sub-study  
AUC and trough SC at Week 24 were 
removed as HPA axis secondary endpoints. 
Day 1 assessments were clarified.  
sub-study as well, so is not needed. 
The AUC0-24 is already a key component in 
the primary endpoint. Trough SC 
concentration is not being defined as a 
distinct endpoint, since there will be 
summaries of serum cortisol concentration 
by time point.  
Day 1 assessments were edited to reflect that 
FEV1 AUC0-4 is already covered by that 
endpoint being specified elsewhere, and 
response defined as an improvement of 100 
mL is also of interest. 
Synopsis, Section 9.4.2, and Section 9.4.4.2 
A separate margin of 75 mL is specified for 
post-dose FEV1 measures. 
The margin for FEV1 AUC0-4 is larger since 
larger benefits and greater variability is 
expected.  
Section 5.4.4/Other Prohibited Medications 
Table 3 - Added NaSSAs to row containing 
SSRIs and SNRIs. Added note to 
specify/clarify use topical medications. 
Table 4 - Moved Carvedilol from table to a 
footnote. Added footnote to clarify usage. 
Paragraph below Table 4 - For consistency 
added language clarifying continuation in the 
study after randomized treatment 
discontinuation. 
Added or reorganized language to provide 
consistency across protocol sections. 
Section 5.7/Reasons for Treatment 
Discontinuation or Study Withdrawal 
Created third-level sections for “Reasons for 
Treatment Discontinuation” and “Reasons 
for Study Withdrawal”. 
Reorganized language to separate reasons for 
treatment discontinuation and study 
withdrawal. 
Sections 4.1, 7.1.4.5 and 9.4.4.5 and 
Appendix 12 
Modified based on name change.  The 
EXACT name was used in the protocol 
Noted the updated EXACT questionnaire 
nomenclature based on recognition of the 
new name “the Evaluating Respiratory 
Symptoms (E-RS) measure”, announced 7 
March 2016. When referring specifically to 
its use in COPD, the proposed context of use

unless specifically noted otherwise. 
for qualification, the full name is now 
“Evaluating Respiratory Symptoms in COPD 
(E-RS™: COPD)”. 
Section 7.2.1/Medical/Surgical History and 
Physical Examination. 
Added “or Treatment Discontinuation 
Withdrawal Visit”. 
Changed to maintain consistency throughout 
the protocol and reflect study conduct. 
Section 7.5.7.3/Pneumonia 
Replaced PAC with CEC. 
Corrected the name of the adjudication 
committee. 
Section 7.5.13/Paternal Exposure  
Added New Section “Paternal Exposure”. 
Added to clarify protocol conduct and 
consistency across protocol sections. 
Section 9.3/Study Populations 
A more complete definition of the mITT 
Population is provided. 
Demography and baseline characteristics will 
be produced for the mITT Population.  
Added to provide additional clarity about the 
data to be included in the mITT Population. 
The main population for demography and 
baseline characteristics was changed from the 
ITT to the mITT Population to reflect the 
primary analyses. Note that the baseline 
information is expected to be identical for the 
mITT and ITT Populations. 
Section 9.4/Efficacy Analyses 
Added Section 9.4.1 on “Estimands” and 
modified text based on estimands in Sections 
9.4.2.1, 9.4.2.2, 9.4.3, 9.4.3.7, 9.4. 
Added the attributable estimand. 
Added missing approaches by comparison in 
9.4.2.1. 
Added estimands to Section 9.4.5 “Control of 
Type I Error” and sub-sections 9.4.5.1, 
9.4.5.2, and 9.4.5.3. 
Added Type I error control for the US 
approach. 
Added Estimands to Section 9.15 “Handling 
The efficacy analysis section has been 
updated using wording around estimands in 
keeping with current statistical thinking. As 
such, analyses previously using the mITT 
Population, the ITT Population, and the Per-
Protocol Population have been replaced with 
the efficacy estimand and attributable 
estimand, the treatment policy estimand, and 
the per-protocol estimand, respectively. The 
new estimand called the attributable estimand 
has been added to further evaluate benefit of 
treatments in the context of having missing 
data. This attributable estimand has been 
added to the Type I error control. 
Type I error control was added for the US 
approach corresponding to the addition of US 
endpoints.

of Missing Data”. 
The non-inferiority margin for TDI was 
changed from 1.0 to 0.75. 
The TDI margin was tightened to be less than 
the minimum clinically relevant difference.  
Non-inferiority margins for other secondary 
measures are specified in the SAP. 
Section 9.5/Subgroup Analyses 
Important Chinese and Asian subgroups were 
added as were primary endpoints. 
The Chinese and Asian subgroups are also 
important to mention that they are planned 
for analysis.  The mention of primary 
endpoints was inadvertently left out of 
previous versions. 
Section 9.7/Pharmacokinetic Analyses 
Comparison to Symbicort was added. 
The comparison to Symbicort TBH was 
inadvertently left out of previous versions. 
Section 9.15/Handling of Missing Data 
Text was edited to specify that exploration of 
the potential impact of missing data will be 
explored and that details will be provided in 
the SAP. 
It is not considered optional to explore the 
potential impact of missing data. 
Other administrative changes to correct and/or clarify protocol language were also 
addressed. These changes included edits for consistency, grammar, and typographical 
errors, which are not summarized in this table.

Study Design: 
This is a multicenter, randomized, double-blind, parallel-group, chronic-dosing (24 weeks) 
study to assess the efficacy and safety of BGF MDI, GFF MDI, BFF MDI compared with 
Symbicort TBH as an active control, in subjects with moderate to very severe COPD. 
This study will be conducted at approximately 160 sites, contributing approximately 10 to 20 
subjects per site.  Across these sites, it is planned that approximately 1800 subjects with 
moderate to very severe COPD will be randomized to the study to provide approximately 
1600 subjects who will complete the study. 
Subjects will be randomized in a 2:2:1:1 scheme.  Approximately 600 subjects each will be 
randomized to the BGF MDI and GFF MDI treatment groups, and 300 subjects each will be 
randomized to the BFF MDI and Symbicort TBH treatment groups.  Randomization will be 
stratified by reversibility to Ventolin HFA, country, and disease severity. 
This study will evaluate the benefit of BGF MDI compared to BFF MDI, GFF MDI, and 
Symbicort TBH, and will also compare BFF MDI to Symbicort TBH with respect to lung 
function in subjects with moderate to very severe COPD that remain symptomatic (COPD 
Assessment Test ≥10) on 2 or more inhaled maintenance therapies.  A history of 
exacerbations in the prior year will be obtained to characterize the population, but the entry 
criteria do not require an exacerbation in the prior year.  COPD severity as defined as post-
bronchodilator forced expiratory volume in 1 second (FEV1) must be <80% predicted normal 
value, calculated using the Third National Health and Nutrition Examination Survey 
reference equations or local reference equations provided by the Sponsor, and the measured 
FEV1 must also be ≥25% of predicted normal value. 
Reversibility of FEV1 to Ventolin HFA, a short acting β2 agonist and to Atrovent HFA, a 
short-acting muscarinic antagonist will be tested at Visits 2 and 3, respectively.  The 
spirometry data obtained at Visit 2 will be used for stratification purposes. 
After the Randomization Visit (Visit 4), subjects will be examined at Visit 5 (Week 4), Visit 
6 (Week 8), Visit 7 (Week 12), Visit 8 (Week 16), Visit 9 (Week 20) and Visit 10a (Week 
24).

For subjects who remain on treatment throughout the study (i.e., complete Visit 10a), a 
follow-up telephone call will be performed at least 14 days after the last study drug dose.   
Subjects who discontinue study treatment prior to Week 24 (Visit 10a) will be encouraged to 
remain in the study to complete all remaining study visits during the 24 week treatment 
period.  Subjects who agree to continue to be followed post treatment discontinuation will 
sign an ICF addendum.  All subjects who agree to continue study participation beyond 
treatment discontinuation will complete a Treatment Discontinuation/Withdrawal Visit (refer 
to Table 8) prior to transitioning back to regularly scheduled study visits.  Subjects 
participating in a sub-study who choose to discontinue from treatment will only complete 
regularly scheduled visits and not complete any remaining sub-study assessments.  Treatment 
discontinuation subjects will return to appropriate maintenance COPD medications, per the 
investigators discretion.  For subjects recorded as Treatment Discontinuations that do not 
complete at least one post-treatment data collection a telephone follow-up call is required at 
least 14 days after last study drug dose. 
If a subject chooses not to continue with study assessments, at a minimum the subject will 
complete the Treatment Discontinuation/Withdrawal Visit (refer to Table 8).  These subjects 
will return to appropriate maintenance COPD medications, per the investigators discretion.  
A follow-up telephone call will be performed at least 14 days after the last study drug dose.  
In the event the Treatment Discontinuation/Withdrawal Visit is performed >14 days post last 
study drug dosing, a follow-up telephone call will not be required.  These subjects will be 
followed for vital status at 24 weeks post randomization in accordance with the informed 
consent. 
Subjects participating at study centers in Japan will be invited to participate in a 28-week 
safety extension study, Study PT010007.  Any additional assessments required for this 
extension study will be obtained as stipulated in the Study PT010007 protocol. 
This study includes the following 3 sub-studies: 12-hour Pulmonary Function Test (PFT), 
Pharmacokinetic (PK) Profile, and HPA Axis. 
12-Hour Pulmonary Function Test Sub-study: Serial PFTs will be conducted over 12 
hours in a subset of approximately 600 randomized subjects (200 subjects from each of BGF 
MDI and GFF MDI treatment groups, and 100 subjects from each of the BFF MDI and 
Symbicort TBH treatment groups) at Visit 10a (Week 24). 
The PFT sub-study will be conducted at specific sites in the United States (US) that have 
agreed to participate.  Once the target number of subjects has been met, no further enrollment 
will be allowed in the PFT sub-study. 
Pharmacokinetic Sub-study: Pharmacokinetic assessments will be performed in a subset of 
subjects who participate in the PFT sub-study.  Approximately 240 randomized subjects (80 
subjects from each of the BGF MDI and GFF MDI treatment groups, and 40 subjects from 
each of the BFF MDI and Symbicort TBH treatment groups) will be assessed at Visit 10a 
(Week 24). 
Pharmacokinetic assessments will be performed on a subset of PFT sub-study subjects at the 
sites in the US that have agreed to participate.  Once the target number of subjects has been 
met, no further enrollment will be allowed in the PK sub-study. 
HPA Axis Sub-study: Adrenocorticosteroid activity will be assessed in a subset of subjects 
in the PK sub-study.  Serum cortisol will be measured in approximately 108 randomized

It is planned that each subject will receive study treatment for 24 weeks. 
Duration of Study:  
The entire study period is scheduled to take approximately 30 weeks (expected range 
between 27 to 30 weeks) for each individual subject.  The study is anticipated to run for 
approximately 18 months and is not expected to exceed 30 months. 
Efficacy Assessments: 
All efficacy assessments are relative to pre-dose baseline obtained at or prior to Visit 4.  The 
primary endpoints, treatment comparisons of interest, and analysis timeframes may differ by 
country or region due to local regulatory agency requirements.  The 3 different registration 
approaches will be called: (1) Japan/China, (2) Europe (EU)/Canada, and (3) US.  Countries 
not specifically mentioned will be decided by regulatory requirements and included in one of 
the three defined registration approaches.  The multiplicity controls for the primary and 
secondary measures will be delineated by approach. 
Primary Efficacy Endpoints: 
Primary Endpoint (Japan/China Approach) 
• Change from baseline in morning pre-dose trough FEV1 over Weeks 12 to 24 (BGF MDI 
versus BFF MDI, BGF MDI versus GFF MDI, and BFF MDI versus Symbicort TBH) 
 
Primary Endpoints (EU/Canada Approach) 
• FEV1 area under the curve from 0 to 4 hours (AUC0-4) over 24 weeks (BGF MDI versus 
BFF MDI and BGF MDI versus Symbicort TBH) 
• Change from baseline in morning pre-dose trough FEV1 over 24 weeks (BGF MDI 
versus GFF MDI and BFF MDI versus Symbicort TBH[non-inferiority])

use at Screening as categorical covariates and baseline trough FEV1, baseline eosinophil 
count, and percent reversibility to Ventolin HFA as continuous covariates.  An unstructured 
covariance matrix will be used to model correlation within a subject.  If this model fails to 
converge, a first order autoregressive structure will be used; for this model, subject will be 
considered a random effect.  Two-sided p-values and point estimates with  
2-sided 95% confidence intervals will be produced for each treatment difference.  All 
comparisons will be for superiority, except the comparison of BFF MDI to Symbicort TBH, 
which will be for non-inferiority and will use margins of 50 mL for trough FEV1 and 75 mL 
for FEV1 AUC0-4.  Analyses of change from baseline in FEV1 AUC0-4 will use a similar 
model to trough FEV1.  Sensitivity analyses will also be conducted to evaluate the robustness 
of the primary analyses to the nature of the missing data. 
Sample Size:  
It is estimated that a sample size of 1800 randomized subjects (600 per arm in the BGF MDI 
and GFF MDI groups and 300 per arm in the BFF MDI and Symbicort TBH groups) will 
provide the following power estimates, all assuming Type I error control at a 2-sided alpha 
level of 0.05 unless specified otherwise: 99% power to detect a difference of 75 mL between 
BGF MDI and BFF MDI in FEV1 AUC0-4 over 24 weeks; 96% power to detect a difference 
of 35 mL between BGF MDI and GFF MDI in morning pre-dose trough FEV1 over 24 weeks 
and approximately 92% power over Weeks 12 to 24; 97% power to detect a difference of 50 
mL between BGF MDI and BFF MDI in morning pre-dose trough FEV1 over Weeks 12 to 
24; and 96% power to demonstrate non-inferiority of BFF MDI to Symbicort TBH in 
morning pre-dose trough FEV1 over 24 weeks and approximately 92% power over Weeks 12 
to 24 based on a margin of 50 mL (1-sided, alpha=0.025) assuming no true difference.   
Assumptions regarding variability for the primary endpoint are based on Pearl’s experience 
with Phase IIb and III clinical studies.  A composite value standard deviation (SD) of 200 mL 
for the change from baseline at each visit has been assumed for trough FEV1 and 220 mL for 
FEV1 AUC0-4.  Dropout is anticipated to be approximately 12% by the end of the study.  
Based on the repeated-measures analysis, an effective SD for the change over 24 weeks of 
157 mL and 173 mL for trough FEV1 and FEV1 AUC0-4, respectively, is assumed.  For 
Weeks 12 to 24, an effective SD for trough FEV1 of 171 mL is assumed.

Data Monitoring and Clinical Endpoint Committees:  
Data Monitoring Committee:  
An external Data Monitoring Committee will be set up to provide systematic and unbiased 
assessment of safety for Study PT010006.  Members of the DMC will review data at 
predetermined intervals.  If significant safety issues arise in between scheduled meetings, ad 
hoc meetings will be scheduled to review the data.  Based on the safety implications of the 
data, the DMC may recommend modification or termination of the study. 
Clinical Endpoint Committee: 
An external clinical endpoint committee will be established for this study.  The committee 
will provide systematic and unbiased assessment of pre-defined, Investigator reported 
adverse events.  The committee will consist of experts who will provide a centralized review 
functioning independently of Pearl.  Three Clinical Endpoint Adjudication Charters will 
outline the clinical endpoints for adjudication.

INTRODUCTION 
Chronic obstructive pulmonary disease (COPD) is a common preventable and treatable 
disease characterized by persistent airflow limitation that is usually progressive and 
associated with an enhanced chronic inflammatory response in the airways and the lung to 
noxious particles or gases.  Exacerbations and co-morbidities contribute to the overall 
severity in individual patients.  Chronic obstructive pulmonary disease is a leading cause of 
morbidity and mortality worldwide and results in significant economic and social burden that 
is both substantial and increasing.  Pharmacologic therapy in COPD is used to reduce 
symptoms, reduce the frequency and severity of exacerbations, and improve health status and 
exercise tolerance as described in the Global Initiative for Chronic Obstructive Lung Disease 
(GOLD) and Japanese Respiratory Society (JRS) guidelines (GOLD 2014, JRS 2013) 
Bronchodilator medications are central to the symptomatic management of COPD.  The 
principal bronchodilator treatments are β2-agonists, anticholinergics, and methylxanthines 
used as monotherapy or in combination.  Treatment with long acting bronchodilators is more 
convenient and more effective at producing maintained symptom relief than treatment with 
short acting bronchodilators. 
Regular treatment with inhaled corticosteroids (ICS) improves symptoms, lung function, and 
quality of life and reduces the frequency of exacerbations in subjects with COPD with a 
forced expiratory volume in 1 second (FEV1) value of <60% of predicted.  Withdrawal from 
treatment of ICS may lead to exacerbations in some patients.  When combined with a long 
acting β2 agonist (LABA), an ICS is more effective than the individual components in 
improving lung function, quality of life, and reducing exacerbations in subjects with 
moderate to very severe COPD (GOLD, 2014). 
Pearl Therapeutics, Inc.  (hereinafter referred to as Pearl) is developing the fixed-dose ICS/ 
long-acting anti-muscarinic agent (LAMA)/LABA triple combination product, Budesonide, 
Glycopyrronium, and Formoterol Fumarate Inhalation Aerosol (PT010), hereafter referred to 
as budesonide, glycopyrronium, and formoterol fumarate metered dose inhaler (BGF MDI), 
for the treatment of patients with COPD.  Budesonide and Formoterol Fumarate Inhalation 
Aerosol (PT009, hereinafter referred to as budesonide and formoterol fumarate (BFF) MDI is 
also being developed as a twice daily (BID) fixed dose ICS/LABA treatment for patients 
with COPD.  Glycopyrronium and Formoterol Fumarate Inhalation Aerosol (PT003) 
hereinafter referred to as glycopyrronium and formoterol fumarate (GFF) MDI is being 
developed as a BID maintenance bronchodilator treatment in patients with COPD. 
Budesonide is a well-established corticosteroid approved worldwide in monotherapy and 
combination therapies for treatment of asthma and allergic rhinitis.  It is available in both 
intranasal and orally inhaled formulations.  Inhaled budesonide in combination with 
formoterol fumarate dihydrate, i.e., Symbicort is approved for use in patients with COPD.   
Glycopyrronium is a LAMA which exerts its bronchodilatory effect via muscarinic receptors 
located on smooth muscle cells within the trachea and bronchi.  Glycopyrronium is approved 
in many countries in multiple formulations for different indications, including for the

treatment of COPD.  In addition, tiotropium bromide (Spiriva®) is approved worldwide and 
has been shown to reduce the rate of COPD exacerbations and to improve the effectiveness 
of pulmonary rehabilitation (Niewoehner, 2005; Casaburi, 2005). 
Formoterol fumarate is a selective LABA approved worldwide for use in asthma and COPD.  
In addition, formoterol fumarate is also approved worldwide in combination with budesonide 
(e.g., Symbicort® MDI, Symbicort® Turbuhaler® (TBH [AstraZeneca, LP]) for use in patients 
with asthma and COPD.  When inhaled, formoterol fumarate acts locally in the lung as a 
bronchodilator.  Formoterol fumarate stimulates β2-adrenoreceptors in the airways, inducing 
airway smooth muscle relaxation and reducing or preventing bronchoconstriction. 
In clinical studies, Symbicort MDI 320/9 µg administered BID demonstrated significant 
improvements in lung function compared with Budesonide MDI 320 µg BID or formoterol 
fumarate (Oxis® Turbuhaler) 9 µg BID in patients with COPD.  In the clinical studies, 
improvements in secondary endpoints of morning and evening peak expiratory flow and 
reduction in rescue medication use were supportive of the efficacy of Symbicort MDI 320/9 
µg (Symbicort Inhalation Aerosol Prescribing Information, 2012; Rennard, 2009; Tashkin, 
2008). 
This study will assess the efficacy of the triple combination therapy (BGF MDI) to its 
relevant LABA/LAMA and ICS/LABA dual combinations (GFF MDI and BFF MDI) as well 
as to an approved ICS/LABA product (Symbicort TBH).  The study will also evaluate the 
safety of BGF MDI, BFF MDI, GFF MDI, and Symbicort TBH for subjects with moderate to 
very severe COPD. 
1.1 
Study Rationale 
This Phase III study is designed to assess the long-term efficacy and safety of BGF MDI 
compared with GFF MDI, BFF MDI, and Symbicort TBH on lung function, subject-reported 
symptom outcomes, and health status over 24 weeks.  While studies of shorter duration (e.g., 
8 to 12 weeks) may be sufficient for the assessment of bronchodilators, Pearl has chosen to 
characterize efficacy and safety of the aforementioned investigational products for at least 24 
weeks to fully characterize the ICS benefit compared with GFF MDI and to fully characterize 
the LAMA benefit compared with BFF MDI to allow for global registration of BGF MDI.   
Consistent with feedback from global regulatory agencies, this study will evaluate a patient 
population that remains symptomatic despite treatment with 2 or more inhaled maintenance 
medications.  Due to the duration of the Study, a randomized, double-blind (other than the 
open-label active control), parallel-group design was adopted in order to minimize bias in 
treatment allocation and to allow unbiased comparisons of treatment groups. 
BGF MDI, GFF MDI, and BFF MDI will be randomly assigned in a double-blind fashion, 
while Symbicort TBH is included as an open-label treatment arm to allow for safety and 
efficacy comparisons relative to an approved ICS/LABA dual combination.

INVESTIGATIONAL PLAN 
4.1 
Overall Study Design and Plan 
This is a multi-center, randomized, double-blind, parallel-group, chronic-dosing (24 weeks), 
active-controlled study to assess the efficacy and safety of BGF MDI, GFF MDI, BFF MDI, 
compared with Symbicort TBH as an active control in subjects with moderate to very severe 
COPD. 
This study will assess the benefit of BGF MDI compared with BFF MDI, GFF MDI, and 
Symbicort TBH and will also compare BFF MDI to Symbicort TBH with respect to lung 
function in subjects with moderate to very severe COPD that remain symptomatic (COPD 
Assessment Test [CAT] ≥10) on 2 or more inhaled maintenance therapies.  A history of 
exacerbations in the prior year will be obtained to characterize the population, but the entry 
criteria do not require an exacerbation in the prior year.  COPD severity as defined as post-
bronchodilator FEV1 must be <80% predicted normal value, calculated using Third National 
Health and Nutrition Examination Survey (NHANES III) reference equations or local 
reference equations provided by the Sponsor, and the measured FEV1 must also be ≥25% of 
predicted normal value. 
This study will be conducted at approximately 160 sites, contributing approximately 10 to 20 
subjects per site.  Across these sites, approximately 1800 subjects with moderate to very 
severe COPD will be randomized into the study to provide approximately 1600 subjects to 
complete the study. 
Subjects will be randomized in a 2:2:1:1 scheme.  Approximately 600 subjects each will be 
randomized to the BGF MDI and GFF MDI treatment groups, and 300 subjects each will be 
randomized to the BFF MDI and Symbicort TBH treatment groups.  Randomization will be 
stratified by reversibility to Ventolin HFA, country, and disease severity. 
The Screening Period will be comprised of 3 study visits. 
At Visit 1 (Screening), all subjects are to sign an informed consent form (ICF) prior to the 
conduct of any screening assessments.  Subject participation in the sub-studies also will be 
determined at Screening, prior to any study procedures.  At the Screening Visit, the 
Investigator will obtain a medical history including specific cardiovascular history, COPD 
exacerbations within the last year, clinical laboratory tests, physical examination, and any 
required documentation in order to determine eligibility for participation (i.e., inclusion 
/exclusion criteria).  Subjects must meet spirometry criteria for COPD as detailed in the 
inclusion/exclusion criteria. 
During the screening period subjects that are receiving an ICS/LABA will discontinue the 
ICS/LABA, but will continue the ICS component for the remainder of the screening period.   
Similarly, subjects treated with an ICS as part of their inhaled maintenance therapy will also 
be permitted to continue their ICS for the remainder of the screening period.  All subjects 
will receive sponsor-provided open-label Atrovent® hydrofluoroalkane (HFA; ipratropium

bromide inhalation aerosol) administered QID for COPD maintenance.  All subjects will 
receive sponsor-provided Ventolin® HFA (albuterol sulfate inhalation aerosol) for rescue use 
throughout the study.  NOTE: ICS and Atrovent HFA administered during screening will be 
discontinued at Visit 4 prior to randomization. 
Subjects will be issued and trained on the use of the electronic diary (eDiary) at Visit 1 
(Screening) and will be instructed to collect practice data during the Screening Period 
(between Visit 1 and Visit 4).  Subject eDiary compliance will be reviewed at Visits 2 and 3, 
and the subject will be retrained if necessary. 
Subjects who meet all entry criteria (Section 5.1 and Section 5.2) will discontinue any 
prohibited COPD medications for the duration of the study, with a minimum washout period 
observed between Visits 1 and 2 (see Table 1) followed by an adjustment of medications to 
protocol-allowable COPD therapy (see Section 5.4.1) 
Reversibility of FEV1 to Ventolin HFA, a short acting β2 agonist (SABA) and to Atrovent 
HFA, a short-acting muscarinic antagonist (SAMA) will be tested at Visit 2 and 3, 
respectively.  Reversibility testing is described in Section 7.1.1.1.  The spirometry data 
obtained at Visit 2 will be used as an inclusion criterion (Section 5.1).  Re-screening is not 
allowed for subjects who do not meet the spirometry criteria at Visit 1. 
Subjects participating at study centers in Japan will be invited to participate in a 28-week 
safety extension study, Study PT010007.  Any additional assessments required for this 
extension study will be obtained as stipulated in the Study PT010007 protocol. 
This study includes the following 3 sub-studies: 12-hour pulmonary function test (PFT), 
pharmacokinetic (PK), and HPA axis. 
12 Hour Pulmonary Function Test Sub-study (US sub-study only): Serial PFTs will be 
conducted over 12 hours in a subset of approximately 600 randomized subjects (200 subjects 
from each of BGF MDI and GFF MDI treatment groups, and 100 subjects from each of the 
BFF MDI and Symbicort TBH treatment groups) at Visit 10a (Week 24).  On the test day, 
additional serial spirometry will be obtained at 6, 8, 10, 11.5 and 12 hours post-dose (refer to 
Section 7.1.1 and Table 10 for details). 
The PFT sub-study will be conducted at specific sites in the US that have agreed to 
participate.  Once the target number of subjects for recruitment has been met, no further 
enrollment will be allowed in the PFT sub-study. 
Pharmacokinetic Sub-study: Pharmacokinetic assessments will be performed in a subset of 
subjects who participate in the PFT sub-study.  Approximately 240 randomized subjects (80 
subjects from each of the BGF MDI and GFF MDI treatment groups, and 40 subjects from 
each of the BFF MDI and Symbicort TBH treatment groups) will be assessed at Visit 10a 
(Week 24).  Refer to Section 7.3 for PK sample collection requirements and Table 10 for 
timing of PK assessments.

Pharmacokinetic assessments will be performed on a subset of PFT sub-study subjects at 
specific sites in the US that have agreed to participate.  Once the target number of subjects 
for recruitment has been met, no further enrollment will be allowed in the PK sub-study. 
Pharmacokinetic assessments will be performed on a subset of PFT sub-study subjects at 
specific sites that have agreed to participate.  Once the target number of subjects for 
recruitment has been met, no further enrollment will be allowed in the PK sub-study. 
HPA Axis Sub-study: Adrenocorticosteroid activity will be assessed in a subset of subjects 
in the PK sub-study.  Serum cortisol (SC) will be measured in approximately 108 
randomized subjects (36 subjects from each of the BGF MDI and GFF MDI treatment 
groups, and 18 subjects from each of the BFF MDI and Symbicort TBH treatment groups) 
over 24 hours, between Visits 3 and 4 prior to dosing at Randomization and Visit 10a (Week 
24).  Refer to Section 7.4 for HPA Axis sample collection requirements and Table 10 for 
timing of HPA Axis assessments. 
Adrenocorticosteroid activity assessments will be conducted on a subset of PK sub-study 
subjects at specific sites in the US that have agreed to participate in this HPA Axis sub-study.  
Once the target number of subjects for recruitment has been met, no further enrollment will 
be allowed in the HPA Axis sub-study. 
At Visit 4 (Day 1, Randomization), subject eDiary compliance will be reviewed, and subjects 
who are unable to meet the compliance requirement (>70% subject completion of diary 
assessments) in the last 7 days preceding Visit 4, or who are unable to meet the FEV1 
baseline stability criteria, will be considered screen failures (Refer to Section 7.1.2).  
Subjects will be evaluated for FEV1 baseline stability criteria (baseline FEV1 at Visit 4 must 
be within ±20% or 200 mL of mean of the pre-dose FEV1 values obtained at the 2 preceding 
visits [see Section 7.1.1.2]).  Those subjects who remain eligible for participation in the study 
will discontinue their ICS and Atrovent HFA administered during screening and will be 
randomized into 1 of the 4 treatment arms.  Randomization will be centralized through the 
use of an Interactive Web Response System (IWRS). 
Subjects will inhale 2 puffs from their MDI in the morning between 6:00 and 10:00 AM 
(breakfast time) and in the evening between 6:00 and 10:00 PM (dinner time).  Symbicort 
TBH also will be administered as 2 inhalations twice daily. 
After the Randomization Visit (Visit 4), subjects will be examined at Visit 5 (Week 4), Visit 
6 (Week 8), Visit 7 (Week 12), Visit 8 (Week 16), Visit 9 (Week 20) and Visit 10a (Week 
24).  In total, each completed subject will attend 10 scheduled visits in this study for a 
maximum of 30 weeks.  For the assessments scheduled at each of these visits, refer to the 
Schedule of Events (Table 8). 
Mean pre-dose morning PFTs will be assessed at every visit.  Post-dose PFTs will also be 
assessed at all visits (refer to Section 7.1.1 for details). 
Throughout the course of the study the subjects will be required to complete the following 
questionnaires; Baseline Dyspnea Index/Transition Dyspnea Index (BDI/TDI) , St.  George’s

Respiratory Questionnaire (SGRQ), EuroQol 5 Dimensions Questionnaire (EQ-5D-5L), 
Chronic Obstructive Pulmonary Disease Assessment Test (CAT) and Exacerbations of 
Chronic Pulmonary Disease Tool – Patient Reported Outcomes (EXACT, please note new 
name in Section 7.1.4.5 and see Section 8 for details and timing of the assessments).  The 
EXACT nomenclature will be used throughout the protocol unless otherwise noted.  Site will 
be requested to complete HCRU questionnaire throughout the study (see Section 8 for details 
and timing of the assessments).   
For subjects who remain on treatment throughout the study (i.e., complete Visit 10a), a 
follow-up telephone call will be performed at least 14 days after the last study drug dose.   
Subjects who discontinue study treatment prior to Week 24 (Visit 10a) will be encouraged to 
remain in the study to complete all remaining study visits during the 24 week treatment 
period.  Subjects who agree to continue to be followed post treatment discontinuation will 
sign an ICF addendum.  All subjects, who agree to continue study participation beyond 
treatment discontinuation, will complete a Treatment Discontinuation/Withdrawal Visit 
(refer to Table 8) prior to transitioning back to regularly scheduled study visits.  Subjects 
participating in a sub-study who choose to discontinue from treatment will only complete 
regularly scheduled visits and not complete any remaining sub-study assessments.  Treatment 
discontinuation subjects will return to appropriate maintenance COPD medications, per the 
investigators discretion.  For subjects recorded as Treatment Discontinuations that do not 
complete at least one post-treatment data collection a telephone follow-up call is required at 
least 14 days after last study drug dose. 
If a subject chooses not to continue with study assessments, at a minimum the subject will 
complete the Treatment Discontinuation/Withdrawal Visit (refer to Table 8).  These subjects 
will return to appropriate maintenance COPD medications, per the investigators discretion.  
A follow-up telephone call will be performed at least 14 days after the last study drug dose.  
In the event the Treatment Discontinuation/Withdrawal Visit is performed >14 days post last 
study drug dosing, a follow-up TC will not be required.  These subjects will be followed for 
vital status at 24 weeks post randomization in accordance with the informed consent. 
Further details will be provided in the DMC charter and in the Statistical Analysis Plan 
(SAP). 
General Considerations for Treatment Visits 4 through Visit 10a 
• Subjects that are randomized will be instructed to discontinue all previous inhaled 
medication used during the screening period, including protocol adjusted ICS therapy as 
defined at Visit 1 (screening), and only use sponsor provided inhaled study medications 
for the remainder of the study. 
• At the start of each study visit, prior to any study procedures being performed, site 
personnel must confirm the subject withheld all COPD medications, including study 
medication, rescue Ventolin HFA or locally available product (where necessary), for at 
least 6 hours, by confirming the last time of dosing for all COPD medication(s).

• Note: Subjects who inadvertently took COPD medication(s) within 6 hours of the start of 
study procedures must be rescheduled as soon as is practical but within the specified visit 
window.  In addition, before the in-clinic dose is administered, the site must confirm the 
subject met all other protocol specified requirements (e.g., FEV1 baseline stability and 
eDiary compliance). 
• All post-randomization visits will be scheduled relative to Visit 4 (Day 1).  Visits 5, 6, 7, 
8, 9, and 10a will be scheduled 4, 8, 12, 16, 20 and 24 Weeks (± 2 days) of Visit 4, 
respectively.  Sites should make every effort to maintain subjects within the scheduled 
visit window.  If a visit falls outside the expected visit window the subsequent visit 
should still be scheduled as planned relative to Visit 4. 
• Subjects must not ingest xanthine and/or xanthine analogue (caffeine)-containing foods, 
medications, and beverages for at least 6 hours prior to each study visit and for the 
duration of each study visit.  Examples of such products include coffee, tea, chocolate, 
and cola.  Decaffeinated beverages are acceptable. 
• Subjects will be required to refrain from smoking (nicotine gums or patches are allowed) 
for at least 4 hours prior to each study visit and throughout the duration of each study 
visit. 
• In order to minimize diurnal variance, sites should make every effort to assess subjects at 
the same time throughout the study and to discuss the importance of dosing in a timely 
manner, every 12 hours. 
• Subjects will be required to return to the clinic at approximately the same time as Visit 4 
for all treatment visits (± 2 hours) but no later than 10:00 AM and will be required to 
remain at the clinic until completion of all protocol-defined assessments. 
• Sites should make every effort to ensure that the in-clinic dosing time is before 10:00 AM 
and within 12±2 hours of the prior at home evening dosing time. 
• The in-clinic dosing time for study drug (BGF MDI, GFF MDI, and BFF MDI) will be 
recorded as the time of administration of the second puff. 
• To ensure standardization of dosing times, it is recommended that sites encourage 
subjects to maintain a dosing schedule consistent with their in-clinic dosing time and that 
sites call the subject on the day before a scheduled visit and remind the subject of the 
following: 
- 
To take their last dose the evening before the scheduled visit; 
- 
To bring their study medications and eDiary with them to the clinic and to withhold 
all COPD medications (locally available products, if applicable) for at least 6 hours 
prior to PFTs; 
- 
To refrain from ingesting xanthine (caffeine)-containing foods, beverages, or 
medications for at least 6 hours prior to each study visit and for the duration of each 
study visit; 
- 
To refrain from smoking for at least 4 hours prior to the study visit and throughout the 
duration of each study visit. 
• Site personnel will instruct subjects not to take any COPD medications, without site 
personnel permission during a visit until all study procedures have been completed, and 
the subject is discharged.  Site personnel should take every precaution to prevent subject

use of COPD medications during the test day.  Site personnel may request the subject to 
surrender all COPD medications prior to the start of the visit before performing any study 
procedures and return the COPD medications to the subject at the end of the visit when 
all study procedures are completed.  Subjects will be asked to abstain wherever possible 
from using rescue Ventolin HFA during study visits.  If a subject is experiencing severe 
symptoms and requires Ventolin HFA for relief of COPD symptoms at any time during a 
test day, site personnel must note the time and justification of use in the subject’s chart 
and all subsequent spirometry assessments should be stopped.  However, safety 
assessments should be continued at the discretion of the Investigator. 
• Subjects completing Visit 10a may be invited to participate in a safety extension study in 
Japan (Study PT010007) to evaluate the long-term safety of BGF MDI, BFF MDI, and 
GFF MDI for an additional 28 weeks.  All subjects from Japan who volunteer to 
participate in the extension study will complete Visit 10a (Final Study Visit) and Visit 
10b (Safety Extension Study Entry Visit) (refer to the protocol for Study PT010007 for 
additional details).   
• Subjects not participating in the safety extension study (Study PT010007) will complete 
all Visit 10a (Final Study Visit) assessments and will be scheduled for a post study 
follow-up telephone call at least 14 days from Visit 10a.

4.2 
Rationale of Study Design 
This Phase III study is designed to assess the long-term efficacy and safety of BGF MDI 
compared with GFF MDI, BFF MDI, and Symbicort TBH on lung function, subject-reported 
symptom outcomes, exacerbations and health status over 24 weeks.  While studies of shorter 
duration (e.g., 8 to 12 weeks) may be sufficient for the assessment of bronchodilators, Pearl 
has chosen to characterize efficacy and safety of the aforementioned investigational products 
for at least 24 weeks to fully characterize the ICS benefit compared with GFF MDI and to 
fully characterize the LAMA benefit compared with BFF MDI to allow for global 
registration of BGF MDI.   
Consistent with feedback from global regulatory agencies, this study will evaluate a patient 
population that remains symptomatic despite treatment with 2 or more inhaled maintenance 
medications.   
Due to the duration of the Study, a randomized, double-blind (other than the open-label 
active control), parallel-group design was adopted in order to minimize bias in treatment 
allocation and to allow unbiased comparisons of treatment groups. 
BGF MDI, GFF MDI, and BFF MDI will be randomly assigned in a double-blind fashion, 
while Symbicort TBH is included as an open-label treatment arm to allow for safety and 
efficacy comparisons relative to an approved ICS/LABA dual combination. 
In order to place the efficacy and safety of BGF MDI into context, BFF MDI, GFF MDI and 
Symbicort TBH are included in the study.  It is important to ensure that subjects only receive 
the inhaled treatment assigned at randomization.  Those subjects on oral phosphodiesterase 
inhibitors (e.g., roflumilast, theophylline) may continue to use these medications as 
prescribed.  When necessary, subjects will be allowed to use sponsor-provided Ventolin 
(albuterol sulfate) HFA or a locally available and comparable rescue product.   
No currently approved treatment prevents death or irreversible morbidity by influencing the 
course of disease. 
4.3 
Rationale of Dose/Regimen and Duration of Treatment 
The safety and efficacy of the individual components, budesonide, glycopyrronium, and 
formoterol fumarate are well characterized, and all 3 components are components (alone or 
in combination) of approved inhalation products for the treatment of patients with COPD. 
The doses of the glycopyrronium and formoterol fumarate components of BGF MDI and 
BFF MDI match the doses utilized in the GFF MDI development program.  The GFF MDI 
clinical program consisted of 12 clinical studies to support the dose selection of 
glycopyrronium and formoterol fumarate for the dual combination GFF MDI, as well as its 
components GP MDI and FF MDI, in subjects with moderate to very severe COPD.  Based 
on the data obtained through this Phase II program, a dose of GFF MDI 14.4/9.6 μg BID was 
selected for progression into Phase III.  Two Phase III pivotal efficacy and safety studies, and 
one long-term extension study, have recently completed which evaluated the efficacy and

safety of GFF MDI, GP MDI, and FF MDI as bronchodilator treatments in subjects with 
moderate to very severe COPD.   
In order to select the appropriate budesonide dose for Phase III studies, Pearl Therapeutics 
has conducted 2 Phase I PK and safety studies.  Pearl Therapeutics has conducted an initial 
Phase I, single-dose, PK and safety study in healthy adult subjects (Study PT010001) with 3 
doses of the triple combination product, BGF MDI, compared with 2 doses of Symbicort 
MDI and a single dose of the Pearl dual combination product GFF MDI.  The study 
demonstrated that formoterol and glycopyrrolate plasma concentrations following 
administration of all BGF MDI doses were similar to those following GFF MDI 
administration, and budesonide plasma concentrations were comparable between BGF MDI 
and Symbicort MDI.  All treatments were well tolerated with a low frequency of AEs, and no 
untoward safety signals were observed.  The results of Study PT010001 supported the 
evaluation of BGF MDI 320/14.4/9.6 μg and lower doses in further clinical studies, and 
suggested that the addition of budesonide to GFF MDI does not impact the systemic levels of 
either component.   
Pearl Therapeutics also conducted a randomized, double-blind, single-dose crossover study 
(Study PT010002) to evaluate the safety and PK of BGF MDI (320/14.4/9.6 μg), BFF MDI 
(320/9.6 μg), and Symbicort TBH (400/12 μg) in healthy adult subjects.  Study PT010002 
was conducted to investigate the PK comparability of BGF MDI and BFF MDI to Symbicort 
TBH.  The budesonide component of BGF MDI was nearly identical on Cmax with a GMR 
of 1.02 and 90% confidence interval (CI) of (0.81, 1.30), but AUC0-12 was approximately 
25% higher than Symbicort TBH.  Similar results were obtained for the comparison of BFF 
MDI to Symbicort TBH.  Study PT010002 also investigated the potential for a DDI by 
comparing the budesonide and formoterol 12-hour PK profiles following a single dose of 
BGF MDI or BFF MDI.  No DDI was observed as both budesonide and formoterol Cmax and 
AUC0-12 were similar, following administration of either BGF MDI or BFF MDI. 
Based on results from Studies PT010001 and PT010002 and given that higher doses of 
budesonide are approved in many countries for asthma, it is reasonable to progress to the 
320 µg budesonide as the highest dose of BGF MDI and BFF MDI in this study.

entered on the eCRF.  Any current ongoing medications, including OTC drugs and herbal 
supplements, will be allowed provided they are not prohibited by the protocol (refer to 
Section 5.4.1) and are approved by the Investigator.  Subjects should also be instructed to 
contact the Investigator if they develop any illnesses.   
All concomitant medications taken during the study will be recorded on the Concomitant 
Medications eCRF with indication, dose, dose regimen, and dates of drug administration. 
5.4.1 
Allowed Medications to Treat a COPD Exacerbation 
Medications to treat an exacerbation should not be used for more than 14 days.  Recent data 
have suggested that treatment with systemic steroids for shorter periods of time results in 
similar outcomes with less systemic steroid exposure.  Therefore, it is recommended that 
subjects are treated with a 5 day course of steroids (Leuppi, 2013) and no longer than 14 
days.  During a COPD exacerbation, it is important for subjects to be treated as deemed 
appropriate by the treating health care provider.  However, subjects should return to their pre-
exacerbation medication regimen as soon as practical.  
5.4.2 
Pneumococcal and Annual Influenza Vaccination 
All subjects should be vaccinated per local guidelines [current global recommendation per 
local policies, availability, and affordability: GOLD, 2016].  For subjects that have been 
previously vaccinated with pneumococcal vaccine, the investigator should assess whether a 
booster vaccination is required.  Annual influenza vaccine should also be administered per 
local guidelines.  Pneumococcal and/or annual influenza vaccine can be given at Visit 1 or at 
any other visit throughout the study at the discretion of the investigator; however, 
administration should occur after obtaining all requisite PFT assessments for that specific test 
day.  There should be at least 7 days between vaccination and subsequent PFT assessments. 
5.4.3 
Prohibited COPD Medications and Required Washout Period Prior to Visit 2 
Subjects who meet the screening criteria at Visit 1 that are being treated with any of the 
medications listed in Table 1 need to discontinue these medication and observe the minimum 
washout requirement before returning for Visit 2.  These medications are prohibited 
throughout the course of the study, and should a subject require use of any of the listed 
medications, they should be discontinued, unless meeting conditions described in 
Section 5.4.1.

Subjects who meet all entry criteria but are using 1 or more of the prohibited COPD 
medications (previously listed) will have their maintenance therapy for COPD adjusted as 
follows:  
• Subjects taking COPD medications (listed previously) at Visit 1 (Screening) will 
discontinue these medications for the duration of the Study and be switched to Sponsor 
provided Atrovent HFA administered 4 times daily (QID) and Sponsor provided Ventolin 
HFA to be administered up to 4 times per day, as needed, for control of symptoms during 
the Screening Period. 
• Subjects receiving a maintenance dose of an ICS as part of a fixed-dose combination 
therapy containing fluticasone and salmeterol, mometasone and formoterol, budesonide 
and formoterol or fluticasone and formoterol or other approved fixed dose ICS/LABA 
combinations must have been on the ICS component for at least 4 weeks prior to Visit 1 
(Screening) and maintained on a stable dose for at least 4 weeks prior to Visit 1 
(Screening).  These subjects will be switched to the corresponding dose of fluticasone, 
mometasone, or budesonide administered as a single agent BID, with Sponsor-provided 
Atrovent HFA administered QID, and Sponsor-provided Ventolin HFA to be 
administered up to QID, as needed, to control symptoms during the Screening Period. 
• Subjects receiving a maintenance dose of an ICS that is not administered as a fixed-dose 
combination together with a LABA will be permitted to continue the ICS provided they 
have been maintained on a stable dose for at least 4 weeks prior to Visit 1 (Screening). 
• All subjects treated with either a LABA (salmeterol, formoterol, indacaterol, vilanterol, 
olodaterol), or currently-marketed LAMA (tiotropium, aclidinium, glycopyrronium, 
umeclidinium) administered alone, as a loose combination, or as a fixed combination 
(e.g., umeclidinium/vilanterol, Glycopyrronium/indacaterol, aclidinium 
bromide/formoterol fumarate ) will have these medications discontinued and replaced 
with Sponsor-provided Atrovent HFA administered QID, and Sponsor-provided Ventolin 
HFA to be administered up to QID, as needed for control of symptoms during the 
Screening Period. 
 
Note: All adjusted maintenance therapy for COPD, including ICS will be stopped at 
randomization. 
It is preferred that Atrovent and Ventolin be US-sourced products.  In cases where it is not 
possible for the US-sourced product to be used, a locally available product will be provided 
by the Sponsor.  The EU-sourced Symbicort TBH must be used for the active control, and a 
locally available product cannot be substituted for the sponsor-provided Symbicort TBH. 
Subjects receiving the following respiratory medications must discontinue these medications 
at the initial Screening Visit (Visit 1).  The minimum cessation period must be met prior to 
returning for Visit 2.  These medications are not permitted during the study (Table 2).

Other Restrictions, Illicit Drugs, or Drugs of Abuse 
5.5.1 
Illicit Drugs 
Illicit drugs or drugs of abuse will not be allowed from the start of Screening (Visit 1) to the 
end of the Follow-up TC or to whenever the subject withdraws from the study.  If any illicit 
drugs or drugs of abuse are used by the subject during the study, the dates of use and the 
amount will be documented and the subject will be discontinued at the discretion of the 
investigator.  Medical marijuana is not an exclusionary drug if used for medical purposes, 
and there is no change in the dose or frequency of consumption. 
5.5.2 
Dietary Restrictions 
Subjects in the PK sub-study are encouraged to refrain from consuming grapefruits or 
grapefruit juice during the last 4 weeks of the study (i.e., between Visit 9 and Visit 10a).  
After the screening visit (Visit 1), subjects must not ingest xanthine and/or xanthine analogue 
(caffeine)-containing foods or beverages or caffeine containing medications, for at least 6 
hours prior to each study visit and for the duration of each study visit.  Examples of such 
products include coffee, tea, chocolate, and cola.  Decaffeinated beverages are acceptable. 
5.6 
Smoking Status 
Changes in a subject’s smoking status (i.e., stopping or re-starting smoking) may have an 
impact on the efficacy outcome measures.  At all visits, the subject will be asked about any 
recent change in their smoking status (i.e., whether a subject’s status has changed from 
smoker to non-smoker or vice versa).  Any change in smoking status during the Screening 
Period (Visit 1 to Visit 4) will result in a screen failure.  Smoking status changes during the 
24-week Treatment Period will be captured in the eCRF, but the subject will be permitted to 
continue in the study.  Subjects will be required to refrain from smoking (including medical 
marijuana and electronic cigarettes) for at least 4 hours prior to each study visit after the 
Screening Visit, and throughout the duration of each study visit.  Study participants may 
utilize various nicotine replacement treatments such as chewing gum and patches, as needed, 
in accordance with recommendations from the Investigator during the entire study visit. 
Note: For this study, the use of electronic cigarettes will be treated in the same manner as 
smoking. 
5.7 
Reasons for Treatment Discontinuation or Study Withdrawal 
5.7.1 
Reasons for Treatment Discontinuation 
The subject may voluntarily discontinue treatment at any time without prejudice to further 
treatment. 
If a subject experiences any of the changes of concern listed below, a repeat assessment 
should be obtained, and if confirmed, the subject should be discontinued from randomized 
treatment and continued in the study.  The changes of concern include:

• Calculated QTcF intervals >500 msec, and have increased by 60 msec or more over test 
day baseline value. 
• Hepatic impairment defined as abnormal liver function test of AST, ALT or total 
bilirubin ≥3 times upper limit of normal on repeat testing. 
 
If a subject experiences any of the changes of concern listed below, a repeat assessment 
should be obtained, and if confirmed, the Investigator or designee needs to make a 
determination as to the suitability of continuing the subject in the randomized treatment of 
the study.  The changes of concern include: 
• Following dosing, a heart rate increase of >40 bpm from the pre-dose value obtained on 
that specific test day and the measured value is also >120 bpm. 
• Following dosing, a systolic blood pressure increase of >40 mmHg from the pre dose 
value obtained on that specific test day and the measured value is also >160 mmHg. 
• Decrease in creatinine clearance to a value ≤30 mL/minute using CKD-EPI formula or a 
clinically relevant change from baseline as determined by the Investigator. 
 
If a subject requires any of the following prohibited medications, they should be discontinued 
from randomized treatment (see Section 8.7):  
• Initiation of maintenance therapy with any prohibited medications as listed in 
Section 5.4.3.   
• Initiation of maintenance therapy with a LABA (e.g., salmeterol, formoterol, indacaterol, 
vilanterol, olodaterol) administered alone or in combination with an ICS or a LAMA 
(e.g., tiotropium, aclidinium, glycopyrronium, umeclidinium). 
• Change inhaled maintenance therapy during the course of the study. 
 
NOTE: Subjects who suffer a COPD exacerbation (regardless of severity) will remain in the 
study and continue to take their assigned study drug unless the Investigator decides that it is 
in the best interest of the subject to discontinue randomized treatment and/or withdraw from 
the study (see Section 8).  
5.7.2 
Reasons for Study Withdrawal 
Subjects may be withdrawn from the study at any time at their own request, upon request of 
the Investigator, or by Pearl at any time or for any reason.  A subject who withdraws consent 
will always be asked about the reason(s) and the presence of any adverse events (AE).  For 
all subjects who withdraw from the study for any reason, they, their family or healthcare 
providers, will be contacted 24 weeks post randomization to determine vital status, and if 
applicable, cause of death (Section 8.10). 
If a female subject becomes pregnant during the course of the study, the subject will be 
withdrawn from the study and the pregnancy will be followed through delivery or final 
outcome (see Sections 7.2.4.4 and 7.5.12).

Emergency Unblinding of Treatment Assignment 
The IWRS should be used in order to unblind subjects and to unmask drug identity.  When 
the Investigator contacts the system to unblind a subject, he/she must provide the requested 
subject identifying information and confirm the necessity to unblind the subject.  Pearl will 
not provide a disclosure envelope with the clinical supplies. 
The Investigator or treating physician may unblind a subject’s treatment assignment only in 
the case of an emergency, when knowledge of the study treatment is essential for the 
appropriate clinical management or welfare of the subject. 
Whenever possible, the Investigator must first discuss options with the Medical Monitor or 
appropriate study personnel before unblinding the subject’s treatment assignment.  If this is 
impractical, the Investigator must notify Pearl as soon as possible, 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 
recorded in the appropriate data collection tool. 
6.6 
Storage Requirements 
Blinded Supplies should be kept in a secured location.  BGF MDI, GFF MDI, and BFF MDI 
should be stored below 25° C (77° F) in a dry place.  Excursions permitted up to 30° C (86° 
F). 
Symbicort® Turbuhaler supplies: Do not store above 30°C (84° F).  Keep the container 
tightly closed, in order to protect from moisture. 
Ventolin® HFA supplies: Store between 15°C and 25°C (59°F and 77°F).  Store the inhaler 
with the mouthpiece down.  For best results, the inhaler should be at room temperature 
before use.  Do not use or store near heat or open flame.  Exposure to temperatures above 
120°F (49°C) may cause bursting.  Never throw into a fire or incinerator. 
Atrovent® HFA supplies: Store at 25°C (77°F); excursions permitted to 15°C to 30°C (59°F 
to 86°F) [Refer to Unites States Pharmacopoeia Controlled Room Temperature].  For optimal 
results, the canister should be at room temperature before use.  Do not puncture.  Do not use 
or store near heat or open flame.  Exposure to temperatures above 120°F (49°C) may cause 
bursting.  Never throw the inhaler into a fire or incinerator. 
The clinical supplies storage area at the site must be monitored by the site staff for 
temperature consistency with the acceptable storage temperature range specified in 
accordance with the product label.  Documentation of temperature monitoring should be 
maintained. 
6.7 
Instructions for Preparation of Treatments for Administration and 
Dispensing 
6.7.1 
BGF MDI, GFF MDI, BFF MDI 
Individual BGF MDI, GFF MDI, and BFF MDI will be packaged in a foil pouch and 
contained in an individual visit treatment box.  Both the visit treatment box and the foil 
overwrap will have a label with a component ID number.  Confirm that the identifier given 
by IWRS and the component ID number written on the label are the same.  The visit 
treatment box is labeled with a 2 part label.  Write the subject number and treatment visit 
number on each of the 2-part labels.  The ‘tear-off’ part of the label is to be placed onto the 
IWRS confirmation report. 
All MDIs must be primed before the first use.  Priming involves releasing a certain number 
of sprays (4) into the air before the first use of the inhaler.  Shaking and priming the inhaler 
fills a chamber inside the canister with the correct dose and mix of medication so that the 
inhaler is ready to use.

The MDI must be primed in a separate room, away from the subject treatment area.  Each 
dose will consist of 2 puffs from the MDI.  Subjects will be dispensed the MDI and 
instructed to continue taking study medication twice daily, 2 puffs in the morning and 2 puffs 
in the evening approximately 12 hours apart, until subject returns to the clinic.  The MDI 
should be stored at room temperature by the subject, to avoid temperature extremes, and the 
products should not be stored in direct sunlight.  Refer to Appendix 2 for instructions on 
administration and cleaning of BGF MDI, GFF MDI, and BFF MDI.

6.8 
Drug Accountability/Return of Clinical Supplies 
Under no circumstances will the Investigator(s) allow the study drug to be used other than as 
directed by this protocol. 
Investigational clinical supplies must be received by a designated person at the study site, 
handled and stored safely and properly, and kept in a secure location to which only the 
Investigator and designated assistants have access.  Storage conditions for the clinical 
supplies should be observed, monitored and documented.  Clinical supplies are to be 
dispensed only in accordance with the protocol.  The Investigator or designee is responsible 
for keeping accurate records of the clinical supplies received from Pearl, the amount 
dispensed to and returned by the subject, and the amount remaining at the conclusion of the 
study.  Study medication should be handled in accordance with Good Pharmacy Practices 
(i.e., gloves should always be worn by study personnel if directly handling tablets or capsules 
that are returned).  The Clinical Monitor should be contacted with any questions concerning 
investigational products where special or protective handling is indicated.  At the end of the 
study, all clinical supplies including partial and empty containers must be returned as 
directed by Pearl. 
Sites should check with the Pearl representative for appropriate documentation that needs to 
be completed for drug accountability. 
The Investigator or designated assistant should not open individual clinical supply containers 
until all pre-dose assessments have been completed and the subject is eligible to be

Clinical Monitor. 
For each subject, all used study drug materials will be collected.  Used subject supplies will 
be kept at room temperature in a secure and locked cabinet until returned to Pearl or 
designee.   
Note: Used study drug will be stored separately from unused study drug. 
All product complaints (including device malfunctions) must be reported to Pearl using the 
Product Complaints Form provided in each site’s regulatory binder.  Pearl will contact the 
site to evaluate the nature of the complaint and determine what further action is needed.

7.1 
Efficacy Assessments 
7.1.1 
Pulmonary Function Tests 
Forced expiratory spirometry maneuvers for derivation of FEV1, FVC, FEF25-75, and PEFR 
will be assessed using a spirometer that meets or exceeds minimum performance 
recommendations of the ATS (Refer to Appendix 6). 
The volume accuracy of the spirometer is to be checked daily using a 3 L syringe across 3 
flow ranges (i.e., low, medium and high flows), with temperature and barometric pressure 
correction.  The calibration syringe must meet ATS specifications and must not be used 
beyond the expiry date.  Required accuracy is ±3% (i.e., 3.09 L to 2.91 L) (ATS/ERS).  The 
results will be printed and maintained in a calibration log, which will be monitored for 
compliance during the monitoring visits (Refer to Appendix 7, Spirometry Assessment 
Criteria). 
All PFTs including FEV1, FVC, and PEFR as defined in ATS/ERS guidelines will be 
performed in accordance with ATS criteria (Miller, 2005). 
To standardize spirometry, all sites will be provided with identical spirometry systems 
 with customized, study-
specific software.  All study staff responsible for performing pulmonary function testing will 
receive standardized training at the Investigator meetings.  All technicians are required to 
demonstrate proficiency in the use of the equipment and the ability to perform technically 
acceptable PFTs (ATS criteria, Miller, 2005) prior to performing testing on study subjects.  
After each test is performed, the spirometry software will provide immediate feedback to the 
technician indicating whether the effort meets ATS acceptability and repeatability standards.  
All efforts will be stored electronically.  After completion of testing, the study staff will 
electronically transmit the spirometric measurements for centralized quality assurance review 
.  Feedback on the quality of the measurements 
will be provided to the investigational site and to Pearl or designee for central data 
management. 
At Visit 1, a single spirometry assessment will be conducted.   
Note: Spirometry must meet both acceptability and repeatability criteria.  (Refer to Exclusion 
Criteria, Section 5.2).

At Visit 2 and Visit 3, spirometry will be conducted 60 minutes and 30 minutes prior to 
bronchodilator administration and at 30 min post bronchodilator.   
Note: Spirometry must meet both acceptability and repeatability criteria.  (Refer to Exclusion 
Criteria, Section 5.2). 
Spirometry will be conducted 60 minutes and 30 minutes prior to study drug administration 
at Visit 4 through Visit 10a.  The mean of the 60 minutes and 30 minutes pre-dose spirometry 
assessments conducted at Visit 4 will be used to establish baseline FEV1, FVC, FEF25-75, and 
PEFR. 
At Visit 4 (Day 1) through Visit 10a (Week 24) spirometry will be obtained at 15 and 30 
minutes, and 1, 2 and 4 hours post-dosing of study drug.  Note: At Visit 4 (Day 1) only, a 5-
minute post-dose spirometry assessment will also be obtained. 
For subjects participating in the 12-hour PFT sub-study, at Visit 10a (Week 24), 
additional spirometry assessments will be obtained at 6, 8, 10, 11.5 and 12 hours after dosing. 
7.1.1.1 
Characterization of Reversibility 
Reversibility to Ventolin HFA will be evaluated at Visit 2 and reversibility to Atrovent HFA 
will be evaluated at Visit 3.  The procedures will be as follows: 
• Reversibility testing to Ventolin HFA (Visit 2 Only): 
- 
Perform pre-bronchodilator PFTs (-60 min and -30 min) prior to administration of 
Ventolin HFA 
- 
Administer 4 puffs of Ventolin HFA 
- 
Perform post-bronchodilator PFT 30 min after the administration of Ventolin HFA or 
locally available SABA. 
 
• Reversibility testing to Atrovent HFA (Visit 3 Only): 
- 
Perform pre-bronchodilator PFTs (-60 min and -30 min) prior to administration of 
Atrovent HFA. 
- 
Administer 4 puffs of Atrovent HFA  
- 
Perform post-bronchodilator PFT 30 minutes after the administration of Atrovent 
HFA or locally available short-acting anticholinergic 
 
Reversibility will be a comparison of the average best FEV1 effort obtained at -60 min 
and -30 min pre-bronchodilator to the best FEV1 effort obtained at 30 minutes post- 
bronchodilator.  A subject is determined to be reversible to Ventolin HFA or Atrovent HFA, 
if the improvement in FEV1 approximately 30 minutes following administration of 4 puffs of 
Ventolin HFA or Atrovent HFA, respectively, is ≥12% and ≥200 mL.  Reversibility to 
Ventolin HFA (obtained at Visit 2) will be used as a stratification variable at randomization 
to ensure an even distribution of reversibility across the treatment arms.  Reversibility to 
Atrovent HFA will be used to characterize the population.

values obtained at Visit 4 (Randomization), it is important to ensure that the baseline FEV1 is 
stable and reflective of the subjects COPD severity prior to being randomized into the study.  
As such, the baseline FEV1 at Visit 4 must be within ±20% or 200 mL of the mean of the pre 
dose FEV1 obtained at the 2 preceding visits (average of pre-dose FEV1 obtained at Visit 2 
and Visit 3).  At Visit 4, if the pre-dose FEV1 average is outside of the ±20% or 200 mL 
range, but the -30 min assessment is within ±22% or 220 mL, then another assessment may 
be conducted 30 minutes later.  If the last 2 assessments meet the FEV1 baseline stability 
requirements (i.e., within ±20% or 200 mL), the initial 60 minute pre-dose assessment will 
not be used and the last 2 assessments will be used to establish the eligibility criteria.  If the 
test day FEV1 is not within ±20% or 200 mL, the subject will not be randomized and will be 
considered a screen failure. 
7.1.2 
Subject Electronic Diary Data Collection 
Subjects will be provided with an electronic Diary (eDiary) at screening to be completed 
twice daily to record time of study medication administration, daily symptoms using the 
Exacerbations of Chronic pulmonary disease Tool (EXACT) scale (see Section 7.1.4.5), and 
the use of rescue albuterol (Ventolin HFA) throughout their study participation.  The dose 
indicator reading will be recorded from Visit 4 onwards once daily for subject on blinded 
study drug.  Before issuing the eDiary to the subject, site personnel will be responsible for 
programming the eDiary and training the subject on its use. 
During the screening period (between Visit 1 and Visit 4), subjects will be required to 
demonstrate acceptable eDiary collections and compliance in order to be eligible for 
randomization.   
Electronic Diary Compliance Requirement: Subject participation may be terminated at any 
time during the study for the following reasons: 
• Chronic failure, in the judgment of the Investigator, to comply with diary compliance, 
despite documentation at the site of repeated efforts to reinforce compliance.  As defined 
for this study, compliance requires >70% subject completion of diary assessments.  Pearl 
may also instruct a site to discontinue a subject based on consistent noncompliance.   
• Subjects who are unable to meet the compliance requirement (>70% subject completion 
of diary assessments) in the last 7 days preceding the Randomization Visit (Visit 4) will 
be considered a screen failure. 
 
The eDiary data report will be available to site personnel through the vendor's server.  The 
eDiary data report should be reviewed by the study personnel at each visit.  The review 
should verify that morning and evening diary entries have been recorded by the subject for 
compliance requirements.  The EXACT responses will be reviewed at each visit as part of the 
subject diary review.  The subject should be reinstructed, as appropriate, on the importance 
of recording twice daily entries if missing entries are observed.

7.1.2.1 
Rescue Medication Usage 
The subject will record the total number of “puffs” of rescue medication (i.e., albuterol 
sulfate or locally available equivalent product) used on a daily basis in the eDiary.  The 
number of “puffs” of rescue product will be recorded as the number of actuations on the 
canister.  For example, when rescue product is required and 2 actuations are inhaled, this 
should be recorded as 2 “puffs.” In the event the subject requires 4 actuations, this should be 
recorded as 4 “puffs”.  Subjects requiring more than 8 puffs per day on 3 consecutive days 
with worsening symptoms should contact the site. 
7.1.2.2 
Medication Compliance 
Time of dosing with study medication will be recorded in the subject’s eDiary for each day 
of treatment (except the in-clinic dosing time).  Study medication compliance will be 
checked at all visits, and any issues identified will be documented in the appropriate study 
files. 
7.1.2.3 
Major/Minor Symptom Worsening Assessment and Alert System 
All major and minor symptoms of a worsening event will be captured once each morning for 
the purposes of a symptom worsening alert.  The purpose of this alert is to notify both the 
subject and the site of a potential symptom worsening event that warrants contact between 
the subject and site for further evaluation. 
All questions will have a 24-hour recall period.  Questions pertaining to the severity of 
symptoms versus their usual state will have 3 response options (e.g., How breathless have 
you been in the last 24 hours? Less breathlessness than usual, Usual level of breathlessness, 
More breathless than usual) whereas questions related to the presence or absence of a 
symptom will have a dichotomous response (e.g., Have you had a sore throat in the last 24 
hours? No, Yes, I had a sore throat). 
An alert will be triggered if 2 or more major symptoms (dyspnea, sputum volume, and 
sputum color) worsen for 2 consecutive days or if 1 major symptom and 1 minor symptom 
(sore throat, cold, fever without other cause, cough, and wheeze) worsen for at least 2 
consecutive days.  When either of these criteria is met, the subject will be alerted via the 
eDiary to contact the site as soon as possible for further evaluation.  Likewise, the study site 
will be alerted to contact the subject within approximately 24 to 72 hours if he/she has not 
yet contacted the study site for further evaluation. 
7.1.3 
COPD Exacerbations 
A COPD exacerbation will be defined as a change in the subject’s usual COPD symptoms 
that lasts 2 or more days, is beyond normal day-to-day variation, is acute in onset, and may 
warrant a change in regular medication.  The change in symptoms must include at least one 
major COPD symptom and at least one other major or minor symptom from the list below: 
• Major COPD symptoms: dyspnea, sputum volume, and sputum color

Page 65 of 184 
• Minor COPD symptoms: cough, wheeze, sore throat, cold symptoms (rhinorrhea or nasal 
congestion), and fever without other cause  
 
If symptoms are acute or have progressed rapidly and require treatment less than two days 
from onset of symptoms, the investigator will have to justify the decision for defining the 
event as an exacerbation and record it in the eCRF.   
If a subject’s symptoms and the overall clinical findings support the diagnosis of a COPD 
exacerbation, but the subject has not experienced a worsening of at least one major COPD 
symptom and at least one other major or minor symptom, the investigator will have to justify 
the decision for defining the event as an exacerbation and record it in the eCRF. 
7.1.3.1 
Severity of COPD Exacerbation 
COPD exacerbations will be classified as mild, moderate or severe based on the following 
criteria: 
Exacerbations will be considered moderate if they result in:  
• Use of systemic corticosteroids and/or antibiotics for at least 3 days; a single depot 
injectable dose of corticosteroids will be considered equivalent to a 3-day course of 
systemic corticosteroids 
 
Exacerbations will be considered severe if they result in:  
• An inpatient COPD-related hospitalization (documentation stating that the subject was 
hospitalized for the COPD exacerbation or a record of the subject being admitted for ≥24 
hours to an observation area, the emergency department, or other equivalent healthcare 
facility depending on the country and healthcare system). 
• COPD-related death 
 
Exacerbations will be considered mild if they do not meet the requirements to be classified as 
moderate or severe but otherwise fulfill the definition of COPD exacerbation. 
7.1.3.2 
Duration of COPD Exacerbation 
For moderate or severe exacerbations, the duration is defined by the length of prescribed 
treatment, whereas for mild exacerbations, the duration is defined by the length of symptoms. 
For moderate or severe COPD exacerbations, the start date will be defined as the start date of 
prescribed treatment with a systemic corticosteroid or systemic antibiotic and the stop date 
will be defined as the last day of prescribed treatment with a systemic corticosteroid or 
systemic antibiotic.  In order to ensure that the same event is not counted twice, concurrent 
moderate or severe COPD exacerbations with start and stop dates equal to or less than 7 days 
apart will be considered the same event and assigned the maximum severity between the two.

Page 66 of 184 
For mild COPD exacerbations, start date will be defined as the onset of worsened symptoms 
as recorded by the subject in the eDiary, and the stop date will be defined as the last day of 
worsened symptoms.  In order to ensure that the same event is not counted twice, mild COPD 
exacerbations with start and stop dates equal to or less than 7 days apart will be considered 
the same event. 
7.1.3.3 
Approach for Capturing COPD Exacerbations 
All moderate or severe COPD exacerbations must be captured using the COPD Exacerbation 
eCRF.  Mild COPD exacerbations will be captured based on symptoms as recorded by the 
subject in the eDiary.  COPD exacerbations of any severity will be considered expected study 
endpoints and will not be reported as adverse events (AEs) unless considered a serious AE 
(SAE). 
7.1.3.4 
Other Information 
Pearl Therapeutics will be using an electronic diary (eDiary) to capture daily symptom 
reporting.  If symptoms meet a specific threshold (i.e., one major COPD symptom and at 
least one other major or minor symptom for 2 consecutive days), the eDiary generates alerts 
to the subject and the clinical site.  This alert is intended to generate a contact between the 
subject and the clinical investigator.  The clinical investigator makes the decision to escalate 
or initiate treatment (steroids and/or antibiotics and/or hospitalizations). 
Circumstances will occur where symptoms are not captured in the eDiary (e.g.  technical 
difficulties, rapid deterioration, or sudden death).  In these cases, the investigator or designee 
will enter the information into the eCRF to capture the symptoms related to a COPD 
exacerbation. 
7.1.3.5 
Investigator-Judged COPD Exacerbations 
For events which do not meet the outlined symptom criteria and/or when symptoms have a 
shorter duration, the investigator can justify the decision for considering the event an 
exacerbation.  Exacerbations could be defined by an investigator when symptoms of COPD 
warranted urgent treatment due to rapid onset or rapidly progressive symptoms.  Such a 
situation does not allow enough time to strictly fulfill the criteria for symptom duration (≥2 
consecutive days).  In these cases, the investigator may define such an event as a COPD 
exacerbation.  As clinical presentations may vary among patients with COPD, exacerbations 
defined by an investigator can be supported by respiratory symptoms that may not strictly 
fulfill all symptom requirements defined above.  Since the investigator will need to document 
the symptoms that justify his or her decision to begin treatment defining a COPD 
exacerbation event, all exacerbations in the study will have documented symptoms justifying 
their clinical relevance. 
7.1.4 
Subject Questionnaires 
The following subject questionnaires will be completed by subjects using the study-supplied 
electronic questionnaire devices at specified visits throughout the study: CAT, SGRQ, and

EQ-5D-5L.  The BDI/TDI will be interviewer-administered to study subjects using the study-
supplied questionnaire (electronic version) at specified visits throughout the study.  The 
EXACT questionnaire will be captured via the subject eDiary (see Section 7.1.2).  When the 
BDI/TDI, SGRQ, and/or EQ-5D-5L are obtained at the same visit, it is recommended that the 
BDI/TDI be collected first, followed immediately by the SGRQ and then the EQ-5D-5L.   
7.1.4.1 
Chronic Obstructive Pulmonary Disease Assessment Test (CAT) 
The CAT is a self administered questionnaire designed to assess the condition of subjects and 
overall impact of COPD [Jones, 2009].  It has been proven that the CAT has good 
repeatability and discriminative properties, which suggest that it is sensitive to treatment 
effects at a group level.  Since the CAT is designed to assess the impact of COPD on the 
subject by measuring overall impairment, it has moderate correlations with other instruments, 
such as the Modified Medical Research Council Dyspnea Scale, SGRQ, and the 6 minute 
walk test.   
Subjects will complete the CAT (Refer to Appendix 8) at Visit 2.  The CAT score will 
describe the burden and symptomatic impact of COPD in subjects enrolled in the Study and 
will be used to determine subject eligibility to participate in the study. 
7.1.4.2 
Baseline and Transition Dyspnea Indices 
Dyspnea is the primary symptom of COPD and its relief is an important goal of therapy.  In 
the evaluation of pharmacotherapy for COPD, several instruments are available to provide a 
discriminative and evaluative assessment of dyspnea.  Among these are the BDI and TDI 
indices, which assess breathlessness in components related to functional impairment, 
magnitude of task and magnitude of effort.  The reliability and validity of the BDI have been 
reported (Mahler, 1984).  The validity of the BDI/TDI based on its association with other 
related measures has also been demonstrated (Witek, 2003).  The BDI/TDI questionnaire 
should always be completed before any other assessments are made to avoid influencing the 
responses.  The Interviewer-administered rating of severity of dyspnea at a single state 
provides a multidimensional measurement of dyspnea based on 3 components that evoke 
dyspnea in activities of daily living, in symptomatic individuals.  The BDI score ranges from 
0 (very severe impairment) to 4 (no impairment) for each domain and are summed to 
determine the BDI focal score (0 to 12) (i.e., the lower the score, the worse the severity of 
dyspnea).  The appropriate language version of the questionnaires will be used.  The 
questionnaire can be found in Appendix 9.   
The TDI measures changes in dyspnea severity from the baseline as established by the BDI.  
TDI components are: Change in Functional Impairment, Change in Magnitude of Task, and 
Change in Magnitude of Effort.  The TDI score ranges from -3 (major deterioration) to +3 
(major improvement) for each component.  The sum of all components yields the TDI focal 
score (-9 to +9) (i.e., the lower the score, the more deterioration in severity of dyspnea).  The 
BDI will be completed at Visit 4 (Day 1, prior to study drug administration).  The TDI will 
be completed at each post-randomization visit including the Treatment 
Discontinuation/Withdrawal Visit.

The BDI/TDI should be completed prior to study drug administration and before 
administration of SGRQ Questionnaire. 
7.1.4.3 
St.  George Respiratory Questionnaire 
The SGRQ 4-week recall tool will be used to provide the health status/health-related quality- 
of-life measurements in this study (Refer to Appendix 10).  The appropriate language version 
of the questionnaires will be available in each participating country.  The subject should 
complete the questionnaires in a quiet area and be allowed to ask questions; however site 
staff should take care not to influence the subject’s responses.  The subject will be instructed 
to provide the most accurate and best individualized response about how they felt regarding 
their health status/health-related Quality of Life in the last 4 weeks from the study visit day.  
The questionnaire will be checked for completeness and collected before the subject leaves 
the study site.  At later visits, subjects are not allowed to review their previous responses.   
The SGRQ contains 50 items divided into 3 domains: "Symptoms" concerned with 
respiratory symptoms, their frequency and severity; "Activity" concerned with activities that 
cause or are limited by breathlessness; and "Impacts" which covers a range of aspects 
concerned with social functioning and psychological disturbances resulting from airway 
disease.  A “Total” score combining each domain will be calculated.  In each case the lowest 
possible value is zero and the highest is 100.  Higher values correspond to greater impairment 
of quality of life.  Completed questionnaires will be reviewed and examined by the 
Investigator or designee, before the clinical examination, for responses which may indicate 
potential AEs or SAEs.  The Investigator should review not only the responses to the 
questions in the questionnaire but also for any unsolicited comments written by the subject.  
Investigators should not encourage the subjects to change the responses reported in the 
questionnaire. 
The SGRQ will be completed by the subject prior to study drug administration at Visit 4 
(Day 1) and at each post-randomization visit including the Treatment 
Discontinuation/Withdrawal Visit. 
7.1.4.4 
European Quality-of-Life-5 Dimension Questionnaire 
The EQ-5D-5L is a standardized instrument for use as a measure of health outcome.  
Applicable to a wide range of health conditions and treatments, it provides a simple 
descriptive profile and a single index value for health status [EuroQol, 2014].  The EQ-5D-
5L consists of 2 assessments, a descriptive system and a visual analogue scale (VAS).  The 
descriptive system comprises of the following 5 dimensions: mobility, self-care, usual 
activities, pain/discomfort, and anxiety/depression.  Each dimension has 5 severity levels: no 
problems, slight problems, moderate problems, severe problems, and extreme problems.   
The VAS records the respondent’s self-rated health on a 20 cm, 0-100 vertical scale with 
endpoints labeled “the best health you can imagine” and “the worst health you can imagine”, 
with higher scores corresponding to a better health state.  This information is used as a 
quantitative measure of health as judged by the individual respondents.

The EQ-5D-5L (see Appendix 11) will be completed by the subject prior to study drug 
administration at Visit 4 (Day 1; Randomization) and at each post-randomization visit 
including the Treatment Discontinuation/Withdrawal Visit. 
7.1.4.5 
Exacerbations of Chronic Pulmonary Disease Tool (EXACT) 
The EXACT is a 14-item patient-reported outcome (PRO) instrument developed to assess the 
frequency, severity and duration of COPD exacerbations (Jones, 2011).  The instrument was 
developed for daily, at home, administration using a handheld electronic device.  
Respondents are instructed to complete the diary each evening just prior to bedtime and to 
answer the questions while considering their experiences “today”.  The instrument includes 
assessments of breathlessness (5 items), cough and sputum (2 items), chest symptoms (3 
items), and 4 additional items (difficulty with sputum, tired or weak, sleep disturbance, and 
psychological state).   
The daily EXACT total score is computed across the 14 items and has a range of 0-100 with 
higher scores indicative of greater severity.  Total score changes are used to identify the onset 
and recovery from an EXACT-defined exacerbation event.  In identifying event onset and 
recovery, the EXACT can provide information on event frequency and duration as well as 
event severity. 
The E-RS is an 11-item sub-set of the 14- question EXACT to evaluate the severity of 
respiratory symptoms of COPD (Jones, 2011).  The E-RS was designed to be captured as part 
of the daily EXACT assessment.  On 07 March 2016, the EXACT-Respiratory Symptoms 
Scale was renamed the Evaluating Respiratory Symptoms (E-RS) measure. When referring 
specifically to its use in COPD, the proposed context of use for qualification, the full name is 
now “Evaluating Respiratory Symptoms in COPD (E-RS™: COPD).  Summation of E-RS 
item responses produces a total score ranging from 0 to 40, with higher scores indicating 
greater severity.  In addition to the total score, symptom domain scores can be calculated for 
breathlessness (5 items; score range: 0–17), cough and sputum (3 items; score range: 0–11) 
and chest symptoms (3 items; score range: 0–11) by summing the responses of items within a 
respective domain.  As with the total score, higher domain scores indicate greater severity. 
The EXACT (see Appendix 12) will be completed daily by the subject as part of the eDiary 
assessments. 
7.2 
Safety Assessments 
The safety assessments include physical examination findings, vital signs, ECGs, and clinical 
laboratory tests in addition to recording of AEs. 
7.2.1 
Medical/Surgical History and Physical Examination 
Medical history, including specific cardiovascular history details, will be collected at Visit 1 
(Screening) and updated during the Screening Period (Visit 1 to Visit 4).  The number of 
COPD exacerbations requiring oral steroids and/or oral antibiotics, or hospitalization within 
12 months of Visit 1 (Screening) will be collected.  A complete physical examination will be

performed at Visit 1 (Screening) and at Visit 10a or Treatment Discontinuation/Withdrawal 
Visit.  A complete physical examination will include evaluation of the following: general 
appearance, skin, head, eyes, ears, nose, throat, neck (including thyroid), lymph nodes, chest, 
heart, abdomen, extremities, and nervous system.  Weight, assessed in ordinary indoor 
clothing with shoes removed will be recorded at Visit 1 (Screening) and Visit 10a or 
Treatment Discontinuation/Withdrawal Visit only.  Height will be recorded at Visit 1 
(Screening) only. 
7.2.2 
Vital Sign Measurements 
Vital signs, including Heart rate (HR) and systolic and diastolic blood pressure (DBP), and 
temperature will be assessed as outlined below; assessments may be obtained while the 
subject is resting for 5 minutes in either the supine or seated position. 
A single set of vital signs will be obtained at Visit 1 (Screening) and the Treatment 
Discontinuation/Withdrawal Visit. 
Vital signs will be obtained at Visit 2 and Visit 3 within 60 minutes pre-bronchodilator and at 
30 minutes post-bronchodilator.   
At Visit 4 (Randomization) only, pre-dose vital signs will be obtained two times at least 5 
minutes apart within 1 hour prior to dosing.  Post-dose vital signs will be obtained 30 
minutes and 2 hours post study drug dosing.   
Note: Temperature will be obtained at Visit 1 (Screening) and pre dose at all visits and will 
not be repeated post dose at subsequent time points unless clinically indicated.   
At Visits 5 through 10a:  
• Pre-dose vital signs will be obtained once within 1 hour prior to dosing. 
• Post-dose vital signs will be obtained at 30 minutes and 2 hours post study drug dosing at 
all treatment visits. 
 
For subjects participating in the 12-hour PFT and PK sub-studies at Visit 10a 
(Week 24), additional vital signs will be obtained at 12 hours post study drug dosing.

whole blood will be collected within 30 minutes before administration of study drug. 
Post-Dose Administration - Week 24 (Visit 10a): Approximately 10 mL of whole blood will 
be collected at 2, 5, and 20 minutes, and at 1, 2, 4, 8, 10, and 12 hours post-dose. 
Blood will be collected by direct venipuncture or may be obtained from an indwelling 
intravenous cannula (per the study site’s Standard Operating Procedure [SOP] after review 
by Pearl’s Medical Monitor or designee) using a vacuum collection tube (e.g., Vacutainer™ 
plasma collection tube) containing ethylenediaminetetraacetic acid (EDTA) tripotassium.  
Refer to the Laboratory Manual for details of plasma collection, storage, and handling. 
7.3.1.1 
Procedure for Shipping Blood Samples 
Samples are to be shipped frozen by overnight courier to the central laboratory for analysis.  
Plasma levels of budesonide, glycopyrrolate (the bromide salt of glycopyrronium), and 
formoterol will be determined using a validated High Performance Liquid Chromatography 
tandem Mass Spectrometry methodology.  Instructions for sample handling, storage, and 
shipping will be provided in the Laboratory Manual. 
7.4 
HPA Axis Sub-Study Assessments 
Blood samples to measure serum cortisol will be obtained in a subset of PFT sub-study 
subjects over 24 hours between Visits 3 and 4 prior to dosing at Randomization and Visit 10a 
(Week 24).  It is recommended that subjects provide samples starting 24 hours prior to 
Randomization.  However, the subject can complete the 24-hour blood draws any day 
between Visits 3 and 4. 
Samples will be collected at the following time points: 30 minutes pre-dose, and 1, 2, 4, 8, 
10, 12, 14, 16, 20, 22, and 24 hours post-dose.  Samples will be sent to the central laboratory 
and analyzed for cortisol levels.  These data will also be categorized as normal/abnormal. 
Those subjects participating in the HPA Axis sub-study will also participate in the Week 24 
PK profile sub-study (see Section 7.3). 
7.5 
Adverse Events 
7.5.1 
Performing Adverse Event Assessments 
The Investigator is responsible for promptly documenting and reporting all AEs observed 
during the study in the subject’s case report form and on the AE Reporting Form.  If the AE 
is “alarming,” the Investigator must report the AE immediately to Pearl.  In addition, certain 
AEs (as described in Section 7.5.10) are classified as "serious" and must be reported no later 
than 24 hours after the Investigator recognizes/classifies the event as an SAE to Pearl or its 
designee.

Page 75 of 184 
In the case of SAEs, after discussing the details of the AE, the Investigator and the Medical 
Monitor may discontinue the subject from treatment prematurely. 
7.5.2 
Adverse Event Definitions 
The following definitions of terms are guided by the International Conference on 
Harmonisation of Technical Requirements for Registration of Pharmaceuticals for Human 
Use (ICH), the US Code of Federal Regulations (21 CFR 312.32) and EU Directive 
2001/83/EC and are included herein. 
An AE is any untoward medical occurrence associated with the use of a drug in humans, 
whether or not considered drug related.  An AE (also referred to as an adverse experience) 
can be any unfavorable and unintended sign (e.g., an abnormal laboratory finding), symptom, 
or disease temporally associated with the use of a drug, without any judgment about 
causality.  An AE can arise from any use of the drug (e.g., off-label use, use in combination 
with another drug) and from any route of administration, formulation, or dose, including an 
overdose. 
Adverse events include, but are not limited to: 
• Any symptom or condition not previously reported by the subject (medical history). 
• An exacerbation of a pre-existing symptom or condition. 
• A significant increase in frequency or intensity of a pre-existing episodic event or 
condition. 
• A drug interaction. 
• A condition first detected or diagnosed after study drug administration even though it 
may have been present prior to the start of the study. 
 
An AE does not include: 
• Medical or surgical procedures (e.g., surgery, endoscopy, tooth extraction, blood 
transfusion); the condition that leads to the procedure is an AE (e.g., bleeding esophageal 
varices, dental caries) 
• Overdose of either study drug or concurrent medication without any clinical signs or 
symptoms 
• Non-clinically significant abnormal laboratory values.  (If accompanied by 
signs/symptoms, the signs or symptoms are considered an AE.) 
 
7.5.3 
Pre-Randomization Adverse Events 
Adverse events that occur between the time subject signs the ICF for the study and the time 
when that subject is randomized will be summarized as medical history and not as an adverse 
event unless the event meets the definition of an SAE as defined in Section 7.5.10.

Page 76 of 184 
7.5.4 
Severity 
The Investigator must categorize the severity of each AE according to the following 
guidelines: 
Mild: Associated with no limitation of usual activities or only slight discomfort; generally not 
requiring alteration or cessation of study drug administration; and/or not needing therapeutic 
intervention. 
Moderate: Associated with limitation of usual activities or significant discomfort; generally 
requiring alteration or cessation of study drug administration; and/or requiring therapeutic 
intervention. 
Severe: Associated with inability of subject to carry out usual activities or very marked 
discomfort; considered to be life-threatening; resulting in significant disability or incapacity; 
and requiring therapeutic intervention. 
7.5.5 
Relationship 
The relationship of each AE to the study drug administration will be assessed by the 
Investigator after careful consideration, and according to the following guidelines: 
Definitely: A reaction that follows a reasonable temporal sequence from administration of 
study drug; that follows a known or expected response pattern to the study drug; it disappears 
or decreases on cessation or reduction in study drug dose; and/or it reappears or worsens 
when the study drug is administered. 
Probably: A reaction that follows a reasonable temporal sequence from administration of 
study drug; that follows a known or expected response pattern to the study drug; and/or that 
could not be reasonably explained by other factors such as underlying disease, complications, 
concomitant drugs, or concurrent treatments. 
Possibly: A reaction that follows a reasonable temporal sequence from administration of 
study drug; that follows a known or expected response pattern to the study drug, but that 
could reasonably have been produced by a number of other factors including underlying 
disease, complications, concomitant drugs, or concurrent treatments. 
Not Related: A reaction for which sufficient data exist to indicate that the etiology is 
unrelated to the study drug. 
7.5.6 
Chronic Obstructive Pulmonary Disease Exacerbations 
All moderate or severe COPD exacerbations must be captured using the COPD Exacerbation 
eCRF.  Mild COPD exacerbations will be captured based on symptoms as recorded by the 
subject in the eDiary.  COPD exacerbations of any severity will be considered expected study 
endpoints and will not be reported as adverse events (AEs) unless considered a serious AE 
(SAE).

Page 77 of 184 
Exacerbation(s) of COPD is expected to occur as a progression of disease despite 
standardized drug treatment, or treatment(s) with combination therapies.  As a result, the 
Sponsor has classified this event as a protocol specified criteria expected event.  Any 
individual case safety reports received related to exacerbation of COPD will not be submitted 
on an expedited basis as a Suspected Unexpected Serious Adverse Reaction (SUSAR) unless 
otherwise required as per the Sponsor’s medical assessment. 
7.5.7 
Adverse Events of Special Interest 
Certain AEs have been identified as adverse events of special interest (AESIs) due to the 
class of drugs being studied.  These adverse events will be captured through spontaneous 
reporting and the reporting of these AESIs will be described in the SAP.  Some events are 
described below but this is not a comprehensive list of all AESIs. 
7.5.7.1 
LABA and LAMA Effects 
Known effects of LAMAs and LABAs include cardiovascular effects, ocular disorders, 
urinary retention, gastrointestinal disorders, and anticholinergic effects for LAMAs and 
cardiovascular and tremor effects for LABAs. 
7.5.7.2 
Local Steroid Effects 
Local steroid effects include oral candidiasis, hoarseness candidiasis, oropharyngeal 
candidiasis, dysphonia, and throat irritation. 
7.5.7.3 
Pneumonia 
In order to adequately assess and characterize the risk of pneumonia in patients in a non-
biased manner, an external, independent Clinical Endpoint Committee (CEC), as described in 
the Pneumonia Clinical Endpoint Adjudication Charter, will review all adverse events 
reported as pneumonia to ensure appropriate pre-defined and clinically consistent pneumonia 
criteria are met. 
To standardize the diagnosis of pneumonia a clinically consistent definition of pneumonia 
will be implemented, which will require the following:  
1. Clinical diagnosis of pneumonia by the Investigator 
2. Documentation of chest imaging obtained within 14 days of the diagnosis of pneumonia 
that is compatible with the diagnosis of pneumonia 
3. Treatment with antibiotics (and/or if appropriate antiviral and/or antifungal agents) 
4. At least 2 of the following clinical signs, symptoms, or laboratory findings: 
• Increased cough  
• Increased sputum purulence or production  
• Adventitious breath sounds on auscultation  
• Dyspnea or tachypnea 
• Fever

Page 78 of 184 
• Elevated white blood cell counts 
• Hypoxemia 
 
The CEC will be empowered to request any additional information, including copies of chest 
X-rays or CT scans if needed, to confirm the pneumonia diagnosis.   
Radiographs will be evaluated locally and the results (infiltrate compatible with pneumonia 
(yes/no) will be entered in the eCRF.  If the Investigator becomes aware that a diagnosis of 
pneumonia was made without a chest image having been performed, he or she should obtain 
a chest image (frontal and lateral) up to 10 to 14 days after the date of pneumonia diagnosis. 
7.5.7.4 
Paradoxical Bronchospasm 
Monitoring for paradoxical bronchospasm will occur at each visit during the Treatment 
Period (Visits 4 through 10a) at 15 and 30 minutes post-dose.  In this study, paradoxical 
bronchospasm is defined as a reduction in FEV1 of >20% from baseline (i.e., the mean FEV1 
values obtained 60 and 30 minutes prior to study drug administration) that occurs within 30 
minutes post-dosing with associated symptoms of wheezing, shortness of breath, or cough. 
7.5.8 
Major Adverse Cardiovascular Events 
Due to the prevalence of cardiovascular diseases in patients with COPD, MACE will be 
evaluated according to pre-defined criteria as described in the Cardiovascular and 
Cerebrovascular Clinical Endpoint Adjudication Charter.  The CEC will review potential 
clinical endpoints to determine if the events meet the following MACE criteria: 
• Cardiovascular death 
• Non-fatal myocardial infarction (MI) 
• Non-fatal stroke 
 
The Clinical Endpoint Adjudication Charters will be established to govern these processes as 
described in Section 7.5.16 Clinical Endpoint Committee. 
7.5.9 
Clinical Laboratory Adverse Events 
Many laboratory abnormalities observed during the course of a study will be included under 
a reported AE describing a clinical syndrome (e.g., elevated BUN and creatinine in the 
setting of an AE of renal failure, or decreased hemoglobin in a case of bleeding esophageal 
varices).  Isolated laboratory abnormalities should be reported as AEs if they are considered 
to be clinically significant by the Investigator. 
Criteria for a "clinically significant" laboratory abnormality are: 
• A laboratory abnormality that leads to a dose-limiting toxicity (e.g., an abnormality that 
results in study drug dose reduction, suspension, or discontinuation)

Page 79 of 184 
• A laboratory abnormality that results in any therapeutic intervention (i.e., concomitant 
medication or therapy) 
• Other laboratory abnormality judged by the Investigator to be of any particular clinical 
concern (e.g., significant fall in hemoglobin not requiring transfusion) 
 
For laboratory abnormalities that do not meet the above criteria but are outside of normal 
range (e.g., < or > normal reference range), the Investigator should indicate whether the 
value is clinically significant or not clinically significant for the subject. 
7.5.10 
Serious Adverse Events 
An AE is considered “serious” if, in the view of the Investigator or Sponsor, it results in any 
of the following outcomes: 
• Death 
• A life-threatening AE 
• In patient hospitalization or prolongation of existing hospitalization  
• A persistent or significant incapacity or substantial disruption of the ability to conduct 
normal life functions 
• A congenital anomaly/birth defect. 
 
Important medical events that may not result in death, be life threatening, or require 
hospitalization may be considered serious when, based upon appropriate judgment, they may 
jeopardize the subject or subject and may require medical or surgical intervention to prevent 
one of the outcomes listed in the definition.  Examples of such medical events include 
allergic bronchospasm requiring intensive treatment in an emergency room or at home, blood 
dyscrasias or convulsions that do not result in subject hospitalization, or the development of 
drug dependency or drug abuse. 
Hospitalization for a pre-existing condition, including elective procedures, which has not 
worsened, does not constitute an SAE. 
An AE or suspected adverse reaction is considered “life-threatening’ if, in the view of the 
Investigator or Sponsor, its occurrence places the subject or subject at immediate risk of 
death.  It does not include an adverse reaction or suspected adverse reaction that, had it 
occurred in a more severe form, might have caused death. 
An AE or suspected adverse reaction is considered unexpected if it is not listed in the current 
Investigator brochure or is not listed at the specificity or severity that has been observed. 
7.5.10.1 
Reporting of Serious Adverse Events 
In agreeing to the provisions of this protocol, the Investigator accepts all legal responsibilities 
for AE identification, documentation, grading, assignment of causality, and prompt 
notification of SAEs to Pearl Pharmacovigilance or designee.  All SAEs must be reported to 


Budesonide, Glycopyrronium, and Formoterol Fumarate Inhalation Aerosol

Page 80 of 184 
Pearl Therapeutics no later than 24 hours after the Investigator recognizes/classifies the event 
as an SAE.  At a minimum, a description of the event and the Investigator’s judgment of 
causality must be provided at the time of the initial report using the appropriate form (e.g., 
SAE Report Form).  After the initial report, as necessary, the Investigator must provide any 
additional information on a SAE to Pearl Pharmacovigilance within 2 working days after 
he/she receives that information.  This follow-up information will be a detailed written report 
that may include copies of hospital records, case reports, and autopsy reports, and other 
pertinent documents. 
Post-study SAEs following the last dose of study drug must be reported to Pearl as described 
in Section 7.5.10.3. 
The Investigator is responsible for continuing to report any new or relevant follow-up 
information that he/she learns about the SAE. 
7.5.10.2 
Supplemental Investigations of SAEs 
The Investigator and supporting personnel responsible for subject care should discuss with 
the Medical Monitor any need for supplemental investigations of SAEs.  The results of these 
additional assessments conducted must be reported to Pearl.  If a subject dies during 
participation in the study and a post-mortem examination is performed, a copy of the autopsy 
report must be submitted to Pearl. 
7.5.10.3 
Post-Study Follow-Up of Adverse Events 
Any AEs that are unresolved at the subject’s last AE assessment in the study are followed up 
by the Investigator for as long as medically indicated, but without further recording in the 
eCRF.  Pearl retains the right to request additional information for any subject with ongoing 
AE(s)/SAE(s) at the end of the study, if judged necessary. 
7.5.10.4 
Notification of Post-Study Serious Adverse Events 
Investigators are not obligated to actively follow subjects after the completion of the study.  
However, if the Investigation becomes aware of a post-study SAEs occurring up to 14 days 
following the last dose of study drug must be reported to Pearl, whether or not the event is 
attributable to study drug.  All SAEs must be reported to Pearl no later than 24 hours after the 
Investigator recognizes/classifies the event as an SAE. 
7.5.10.5 
Investigational Research Board/Independent Ethics Committee Notification of 
Serious Adverse Events 
The Investigator is responsible for promptly notifying her/his Investigational Research 
Board/Independent Ethics Committee (IRB/IEC) of all SAEs, including any follow-up 
information, occurring at her/his site and any SAE regulatory report, including any follow-up 
reports that he/she receives from Pearl.  Documentation of the submission to the IRB/IEC 
must be retained for each safety report.  The Investigator is also responsible for notifying

Pearl if their IRB/IEC requires revisions to the ICF or other measures based on its review of 
an SAE report. 
7.5.10.6 
Health Authority Safety Reports 
Pearl or its representatives will submit a safety report to the Food and Drug Administration 
(FDA) and/or any other appropriate regulatory agencies, for any suspected adverse reaction 
that is both serious and unexpected within the appropriate time frame. 
Pearl or its representatives will send copies of each safety report submitted to the FDA and/or 
other regulatory agencies to the Investigators who are actively participating in Pearl-
sponsored clinical studies.  Safety reports must be submitted to the appropriate IRB/IEC as 
soon as possible.  Documentation of the submission to the IRB/IEC must be retained for each 
safety report. 
7.5.11 
Overdose 
An overdose is defined as a dose greater than the high dose level evaluated in this study as 
described in Section 6.2 (Product Descriptions) that results in clinical signs and symptoms.  
In the event of an overdose of study medication, the Investigator should use clinical 
judgment in treating the overdose and contact the study Medical Monitor.  The Investigator 
should refer to the relevant document(s) for detailed information regarding warnings, 
precautions, contraindications, AEs, and other significant data pertaining to the study drug(s) 
being used in this study.  Such document may include, but not be limited to, the 
Investigator’s Brochure for BGF MDI, BFF MDI, GFF MDI, and approved product labeling 
for open-label products. 
7.5.12 
Pregnancy 
To ensure subject safety, each pregnancy in a female subject from Visit 1 (Screening) until 
study completion must be reported to Pearl within 24 hours of learning of its occurrence.  
The pregnancy should be followed up to determine outcome, including spontaneous or 
voluntary termination, details of the birth, and the presence or absence of any birth defects, 
congenital abnormalities, or maternal and/or newborn complications.  Pregnancy should be 
recorded on a Paper Pregnancy Report Form and reported by the Investigator to Pearl 
Pharmacovigilance or designee.  Pregnancy follow-up should be recorded on the same form 
and should include an assessment of the possible relationship to the Pearl study drug of any 
pregnancy outcome.  Any SAE experienced during pregnancy must be reported on the SAE 
Report Form. 
7.5.13 
Paternal Exposure 
Male subjects who are sexually active must agree to use a double barrier method of 
contraception (condom with spermicide) from the first dose of randomized treatment until 2 
weeks after their last dose, and must not donate sperm during their study participation period.  
If a male subject's partner becomes pregnant during the course of the study, it must be 
reported to the Sponsor within 24 hours of the investigator learning of its occurrence.

Hy’s Law 
Cases where a subject shows an AST or ALT ≥ 3x Upper Limit of Normal (ULN) and Total 
Bilirubin (TBL) ≥ 2x ULN may need to be reported as SAEs.  Please refer to Appendix 13 
for further instructions in cases of combined increase of aminotransferase and TBL. 
7.5.15 
Use of Steroids During the Study 
At each visit, subjects will be asked whether they have been administered oral, intramuscular, 
or intravenous corticosteroids since the last visit.  Use of oral, intramuscular, or intravenous 
corticosteroids for the management of COPD exacerbations or other condition is not a reason 
for early treatment discontinuation or study withdrawal.  Use of corticosteroids should be 
documented.  Subjects who are being treated for a COPD exacerbation with oral 
corticosteroids or have been treated for a COPD exacerbation with oral corticosteroids within 
14 days of the scheduled visit will be allowed to perform PFTs under close medical 
supervision.  The Investigator can decide to stop PFTs if subject safety is at risk or symptoms 
make it difficult for the subject to continue. 
Subjects treated with oral, intramuscular, or intravenous corticosteroids for other indications 
will follow their visit schedule.  If a subject requires intraocular corticosteroids, this should 
be fully documented and the Investigator should make a determination as to the suitability of 
the subject continuing on randomized treatment. 
7.5.16 
Clinical Endpoint Committee 
An external CEC will be established for this study.  The committee will provide systematic 
and unbiased assessment of pre-defined, Investigator reported adverse events.  The 
committee will consist of experts who will provide a centralized review functioning 
independently of Pearl.  Three Clinical Endpoint Adjudication Charters will outline the 
clinical endpoints for adjudication.   
• Cardiovascular and Cerebrovascular (CCV) Clinical Endpoint Adjudication Charter 
• Cause-Specific Mortality Clinical Endpoint Adjudication Charter 
• Pneumonia Clinical Endpoint Adjudication Charter 
 
Further details are provided in the Adjudication Committee Charters. 
7.5.16.1 
Cardiovascular and Cerebrovascular Clinical Endpoint Adjudication Charter 
A Cardiovascular and Cerebrovascular Clinical Endpoint Adjudication Charter will be 
referenced for the review and assessment of non-fatal serious CCV events and classification 
of Major Adverse Cardiovascular Event (MACE).  The CEC will review potential clinical 
endpoints to determine if the event meets MACE criteria.

Cause-Specific Mortality Clinical Endpoint Adjudication Charter 
A Cause-Specific Mortality Clinical Endpoint Adjudication Charter will be referenced for the 
review and assessment of the cause of deaths.  The CEC will review fatal reports to 
determine if the event meets MACE criteria.  Cardiovascular deaths will be classified as 
MACE. 
7.5.16.3 
Pneumonia Clinical Endpoint Adjudication Charter 
A Pneumonia Clinical Endpoint Adjudication Charter will be referenced for the review and 
assessment of all pneumonia-related events to ensure appropriate pre-defined and clinically 
consistent pneumonia criteria are met. 
7.5.17 
Data Monitoring Committee 
An external Data Monitoring Committee (DMC) will be set up to provide systematic and 
unbiased assessment of safety for Study PT010006.  Members of the DMC will review data 
at predetermined intervals.  If significant safety issues arise in between scheduled meetings, 
ad hoc meetings will be scheduled to review the data.  Based on the safety implications of the 
data, the DMC may recommend modification or termination of the study. 
7.6 
Health Care Resource Utilization 
The number of days missed from work, days that primary caregivers of subjects missed work 
as a result of the subject’s COPD, telephone calls to health care providers or general 
practitioners (GPs), visits to health care providers or GPs, Emergency Room (ER) visits, days 
in the hospital, days in Intensive Care Units (ICU), days in Coronary Care Units (CCU), and 
use of ambulance transport will be assessed at Visit 5 (Week 4), Visit 6 (Week 8), Visit 7 
(Week 12), Visit 8 (Week 16), Visit 9 (Week 20), Visit 10a (Week 24), and the telephone 
follow up call or Treatment Discontinuation/Withdrawal Visit. 
7.7 
Termination of the Study 
An Investigator may choose to discontinue study participation at any time with sufficient 
notice by the Investigator for any reason as per the terms of the contract with Pearl.   
Pearl reserves the right to discontinue the study at any time for clinical or administrative 
reasons.  Such a termination must be implemented by the Investigator, if instructed to do so 
by Pearl, in a time frame that is compatible with the subjects’ wellbeing.

laboratory assessments, PK, and spirometry. 
a 
Scheduling Visits: The maximum Screening Period is 28 days; the earliest a subject can be randomized from Visit 1 date is 9 days (7 days for LABA 
washout plus 1 day between Visit 2 and 3 plus 1 day between Visit 3 and Visit 4) or 16 days if subject is washing off of tiotropium; Site should make every 
effort to maintain subjects within the scheduled visit window.  Subjects who fall outside the visit window will be placed in the appropriate visit window at 
the next scheduled visit. 
b 
Subjects will be tested for reversibility to albuterol (Ventolin HFA) at Visit 2 and reversibility to Atrovent HFA at Visit 3; Refer to Section 7.1.1.1 for 
additional details 
c 
Subjects will complete the CAT (see Appendix 8) at Visit 2 as an entry criterion.

d 
At all visits beyond Visit 1 (Screening), note time of last dose of short-acting bronchodilator and other COPD medications (if <6 hours, visit should be 
rescheduled). 
e 
Refer to Section 7.1.1 and Table 9 for spirometry assessments and specific time points for these assessments to be performed at each treatment visit. 
f 
Includes evaluation of weight at Visit 1 (Screening) and Visit 10a and evaluation of height at Visit 1 (Screening) only. 
g 
Refer to Section 7.2.2 and Table 9 for vital signs assessments and specific time points for these assessments to be performed at each treatment visit.   
h 
Refer to Section 7.2.3 and Table 9 for ECG assessments and specific time points for these assessments to be performed at each treatment visit. 
i 
Refer to Section 7.2.4 and Table 9 for clinical laboratory assessments (hematology, chemistry and urinalysis) and specific time points for these assessments 
to be performed at each treatment visit.  Serum pregnancy test will be performed at Visit 1 (Screening) and at Visit 10a (Week 24) or at the Treatment 
Discontinuation/Withdrawal Visit.  At Visit 7 (Week 12), a urine pregnancy test will be performed.  Note: A Basic Metabolic Panel (BMP) will be obtained 
at 30 minutes and 2 hours post-dosing at Visit 4 (Day 1), Visit 5 (Week 4), Visit 10a (Week 24) 
j 
Obtain a new chest x-ray (frontal and lateral) at Visit 1 if a chest x-ray or CT performed within the 6 months prior to Visit 1 (Screening) is not available, 
except in countries with restrictive radiology assessment practice, where only subjects who have had a chest x-ray or CT scan (thorax) performed outside of 
the study in the last 6 months are allowed to be enrolled.  Alternatively, in these countries, an MRI should be used instead of a CT scan or chest x-ray as per 
local practice assessment. 
k 
At Visit 1 (Screening), stop prohibited COPD medications and change COPD medications as specified in Section 5.4.1 (i.e., Sponsor provided Atrovent 
HFA with or without ICS).  At the end of Visit 10a, return subject to pre-study or other appropriate inhaled maintenance COPD. 
l 
Sponsor-provided Atrovent HFA or Ventolin HFA is dispensed only after a subject is determined to be eligible to proceed to Visit 2 (i.e., only if a subject 
meets COPD definition following spirometry assessments at Screening). 
m 
When BDI/TDI and SGRQ are obtained at the same visit, it is recommended that the BDI/TDI should be collected first, followed immediately by the SGRQ 
and then the EQ-5D-5L.  The BDI/TDI, SGRQ, and EQ-5D-5L should be completed by the subject prior to any other visit procedures. 
n 
It is recommended that subjects provide these samples 1 day prior to Randomization (see Section 7.4) 
o 
Issue and train subjects on eDiary use, only after a subject is determined to qualify to proceed to Visit 2.  Retraining will be done if necessary at Visits 2 and 
3. 
p 
Refer to Section 7.1.2 for details on eDiary review.  Subjects will be asked to maintain a daily record of their study drug dosing and rescue medication use.  
EXACT will be reviewed at each visit as part of the e Diary review.   
q 
It is recommended that sites call the subject on the day before a scheduled visit and remind the subject of the expectations for the upcoming visit (e.g., 
Dosing appropriately the day before the visit, withholding COPD medications the morning of the scheduled visit, bring all study drug and eDiary to the 
visit). 
r 
Vital status check for all subjects.  For subjects that discontinue, the vital status check will be conducted 24 weeks after randomization. 
s 
These are the minimum procedures that should be completed at a Treatment Discontinuation/Withdrawal Visit.

clinical laboratory assessments, PK, and spirometry. 
a 
In-clinic dosing time is recorded as time of the second puff.  Safety assessments ( vital signs and ECG) should be started approximately 5 to 10 minutes ahead of the specified 
time point to ensure that spirometry assessments for FEV1, FVC, and PEFR will be conducted as close to the specified time points as possible (i.e., FEV1, FVC, and PEFR 
assessments need to be conducted within ±15 minutes of specified time prior to study drug administration; ±5 minutes of specified time point for the first 60 minutes post 
study drug administration; ±15 minutes of specified time point for assessments obtained thereafter). 
b 
This is not a timed assessment.  Sites should plan to perform these activities so as not to interfere with collection of timed assessments such as spirometry. 
c 
At Visit 4 only, pre-dose vital signs will be collected twice, at least 5 minutes apart within 1 hour prior to dosing.  Vital signs will be obtained within 1 hour pre-dosing and at 
30 minutes and 2 hours post-dose at all treatment visits.  Temperature will be obtained pre-dose; no further temperature assessments are required unless clinically indicated. 
d 
At Visit 4 only, pre-dose ECGs will be collected twice, at least 5 minutes apart.  An ECG will be obtained pre-dose and at 30 minutes and 2 hours post-dose Visit 4 (Day 1), 
Visit 5 (Week 4), Visit 7 (Week 12) and Visit 10a (Week 24). 
e 
Clinical laboratory tests ((hematology, chemistry and urinalysis) will be obtained prior to dosing at Visit 4 (Day 1), Visit 5 (Week 4), Visit 7 (Week 12), and Visit 10a (Week 
24) only.  Serum pregnancy test will be performed at Visit 10a (Week 24) and a urine pregnancy test will be performed at Visit 7 (Week 12).   
f 
A Basic Metabolic Panel (BMP) will be obtained at 30 minutes and 2 hours post-dosing at Visit 4 (Day 1), Visit 5 (Week 4), Visit 10a (Week 24). 
g 
The baseline FEV1 at Visit 4 must be within ±20% or 200 mL of the mean of the pre dose FEV1 obtained at the 2 preceding visits (average of pre-dose FEV1 obtained at Visit 
2 and Visit 3).  At Visit 4, if the pre-dose FEV1 average is outside of the ±20% or 200 mL range, but the 30 min assessment is within ±22% or 220 mL, then another

sign an ICF addendum.  All subjects who agree to continue study participation beyond 
treatment discontinuation will complete a Treatment Discontinuation/Withdrawal Visit (refer 
to Table 8) prior to transitioning back to regularly scheduled study visits.  Subjects 
participating in a sub-study who choose to discontinue from treatment will only complete 
regular scheduled visits and not complete any remaining sub-study assessments.  Treatment 
discontinuation subjects will return to appropriate maintenance COPD medications, per the 
investigators discretion.  For subjects recorded as Treatment Discontinuations that do not 
complete at least one post-treatment data collection a telephone follow-up call is required at 
least 14 days after last study drug dose.   
If a subject chooses not to continue with study assessments, at a minimum the subject will 
complete the Treatment Discontinuation/Withdrawal Visit (refer to Table 8).  These subjects 
will return to appropriate maintenance COPD medications, per the investigators discretion.  
A follow-up telephone call will be performed at least 14 days after the last study drug dose.  
In the event the Treatment Discontinuation/Withdrawal Visit is performed >14 days post last 
study drug dosing, a follow-up TC will not be required.  These subjects will be followed for 
vital status at 24 weeks post randomization in accordance with the informed consent. 
8.8 
Unscheduled Visit and Treatment Discontinuation/Withdrawal Visit 
Repeat assessments, if needed, will be captured in unscheduled visits. 
Treatment Discontinuation/Withdrawal Visits will be captured as unscheduled visits.  The 
following minimum procedures will be completed for these types of visits:

PLANNED STATISTICAL METHODS 
9.1 
Introduction 
This study will be conducted as a double-blind, active-control (open-label), and parallel-
group study evaluating the following treatments in approximately 1800 subjects: 
• BGF MDI (320/14.4/9.6 μg BID) 
• GFF MDI (14.4/9.6 μg BID) 
• BFF MDI (320/9.6 μg BID) 
• Symbicort Turbuhaler (400/12 μg BID) 
 
Approximately 1800 subjects with moderate to very severe COPD will be randomized to 
provide approximately 1600 subjects to complete the study.   
The primary objective of this study is to compare the effects of treatment with BGF MDI 
relative to GFF MDI, BFF MDI, and Symbicort TBH on lung function in subjects with 
moderate to very severe COPD.   
This study will include a 24 week Treatment Period, preceded by a Screening Period and 
followed by either enrollment into a 28-week extension study or a 2-week follow-up 
telephone call. 
The primary endpoints, comparisons of interest, and time frames for analyses may differ by 
country or region due to local regulatory agency requirements.  The 3 different registration 
approaches will be called: (1) Japan/China, (2) EU/Canada, and (3) US.  Countries not 
specifically mentioned will be decided by regulatory requirements and included in one of the 
three defined registration approaches. The impact of these approaches is delineated in each of 
the relevant sections below.  Where not specified, a common approach will be used for all 
regions.   
The registration requirements also impact controls for multiplicity; these multiplicity controls 
will be delineated by approach. 
9.2 
Protocol Variables 
9.2.1 
Efficacy Endpoints 
All efficacy assessments are relative to pre-dose baseline obtained at or prior to Visit 4 
(Section 3).

Safety Endpoints 
• Adverse events (AEs) 
• 12-lead electrocardiograms (ECG) 
• Clinical laboratory testing 
• Vital sign measurements 
 
9.3 
Study Populations 
The following analysis populations are defined in this study: 
• The Intent-To-Treat Population is defined as all subjects who are randomized to 
treatment and used any amount of the study treatment.  Subjects will be analyzed 
according to the treatment they were assigned to at randomization.  Data obtained after 
discontinuation of treatment, but prior to withdrawal from the study, will be included 
• The Modified Intent-to-Treat (mITT) Population is a subset of the ITT Population, 
defined as all subjects with post randomization data obtained prior to discontinuation 
from treatment.  Any data collected after completion of or discontinuation from 
randomized study medication will be excluded from the mITT analysis but will still be 
included in the ITT analysis. Subjects will be analyzed according to randomized 
treatment group. (Note that a subject who used a study treatment, but took less than one 
full dose of treatment will qualify for this population). Data obtained after treatment 
discontinuation will be excluded. The mITT Population will be the primary population 
for all efficacy analyses except for the non-inferiority analyses. Note: The knowledge that 
a subject did not have a COPD exacerbation constitutes an efficacy assessment. 
• The Rescue Ventolin User Population is defined as all subjects in the ITT Population 
with mean baseline rescue Ventolin use of ≥1.0 puff/day. 
• The Per-Protocol (PP) Population is a subset of the ITT Population, defined as all 
subjects with post-randomization data obtained prior to any major protocol deviations.  
Data obtained after any major protocol deviation or discontinuation from treatment will 
be excluded.  Since receiving the wrong treatment will be a major protocol deviation, 
subjects in the PP population will be analyzed as randomized (which for this population if 
identical to analysis by the actual treatment received).  Any evaluability criteria with a 
potential impact on efficacy results will be identified in a blinded fashion from review of 
data listings prior to unblinding.  Major protocol deviations (protocol violations), 
therefore, can result in exclusion of all data from a particular subject from the PP 
population or require exclusion of data from a specific time point and/or subsequent time 
points for an endpoint. 
• The Safety Population is similar to the ITT Population (all subjects who are randomized 
to treatment and receive at least one dose of the study treatment).  However, subjects will 
be analyzed according to treatment received rather than randomized.  If a subject received 
more than 1 randomized treatment, they will be analyzed and included in summaries 
according to the treatment they received the most.  Subjects receiving no study treatment

will be excluded, as will subjects who have no post-dose safety assessments.  (Note that a 
subject who used a study treatment, but took less than 1 full dose of treatment will 
qualify for this population).  Note: The statement that a subject had no AEs also 
constitutes a safety assessment 
• The PK Population is defined as all randomized and treated subjects who have sufficient 
data to reliably calculate at least 1 PK parameter.  Subjects will be analyzed according to 
treatment received rather than randomized. 
• The HPA Axis Population consists of subjects who participated in the HPA axis sub-
study and is a subset of the ITT Population without protocol deviations which could 
affect the serum cortisol endpoint and whose serum samples did not have confounding 
factors that would affect the interpretation of the results 
 
Analyses will be performed as follows: 
Demographics will be summarized for the mITT, PP, Safety, and Non-randomized 
Populations.  Extent of exposure will be summarized for the Safety Population.  The Safety 
Population will be used to summarize safety.  Efficacy Analyses will be performed for the 
ITT, mITT, and PP Populations.  The mITT Population using only on-treatment data will be 
considered the primary population for these analyses, with the ITT and PP populations being 
considered supportive.  
9.4 
Efficacy Analyses 
9.4.1 
Estimands 
The primary estimand of interest is called the efficacy estimand and is the effect of the 
randomized treatments in all subjects assuming continuation of randomized treatments for 
the duration of the study regardless of actual compliance. There are three additional 
estimands of interest. One is called the attributable estimand and is the effect of treatment in 
subjects attributable to the randomized treatment. For this estimand, discontinuation of 
randomized medication for reasons such as tolerability or lack of efficacy is considered a bad 
outcome. Another estimand of interest is called the treatment policy estimand. This estimand 
is the effect of randomized treatment over the study period regardless of whether randomized 
treatment is continued. The final estimand of interest is called the per protocol estimand. This 
estimand is the effect of treatment on subjects who are compliant with the protocol (i.e. no 
major protocol deviations), including the use of randomized medication. 
The primary analysis for the efficacy estimand will be conducted using the mITT Population 
where only data obtained prior to subjects discontinuing from randomized treatment will be 
utilized. This assumes that efficacy observed on treatment is reflective of what would have 
occurred after discontinuation of randomized treatment had they remained on treatment.  
The second estimand of interest is the attributable estimand. Analyses of the attributable 
estimand will be conducted in the mITT Population, but data that are missing due to 
treatment discontinuation will be imputed based on the 95th percentile of the reference arms’ 
distribution if the reason is reasonably attributable to tolerability or lack of efficacy. The 95th

percentile applies to an endpoint for which a higher value is a worse outcome; however, the 
5th percentile applies to an endpoint for which a higher value is a better outcome. More 
detail about the computation of the attributable estimand will be provided in the SAP. 
The third estimand of interest is the treatment policy estimand. Analyses of the treatment 
policy estimand will be conducted in the ITT Population, in which all observed data will be 
utilized regardless of whether subjects remain on randomized treatment. The treatment policy 
estimand will be provided as a supporting analysis for all primary and secondary endpoints. 
Finally, the last estimand of interest is the per protocol estimand. Analysis of this estimand 
will use the PP Population. This estimand will serve as primary for the non-inferiority 
comparison of BFF MDI to Symbicort TBH. It will be supportive for all other comparisons 
of interest. 
9.4.2 
Primary Efficacy Analyses 
For the primary comparisons, the null hypothesis for each pair-wise comparison will be that 
the mean treatment difference is zero (mean treatment effects are equal).  The alternative 
hypothesis is that the mean treatment difference is greater (less than) zero (mean treatment 
effects are not equal).   
All comparisons will be for superiority except that the comparison of BFF MDI to Symbicort 
TBH will be for non-inferiority and will use margins (δ’s) of 50 mL for trough FEV1 and 75 
mL for post-dose FEV1 measures.  P-values will be reported as 2-sided.  
9.4.2.1 
Change from Baseline in Morning Pre-dose Trough FEV1 
The primary analysis will be conducted using the efficacy estimand.  The change from 
baseline in morning pre-dose trough FEV1 will be analyzed using a linear model with 
repeated measures (RM).  The model will include treatment, visit, treatment, treatment by 
visit interaction, and ICS use at Screening as categorical covariates and baseline FEV1, 
percent reversibility to Ventolin HFA, and baseline eosinophil counts as continuous 
covariates.  Baseline FEV1 is defined as the average of the non-missing 60 minute and 30 
minute values obtained prior to dosing at Visit 4, and baseline eosinophil count is defined as 
the average of non-missing eosinophil counts prior to treatment.  An unstructured covariance 
matrix will be used to model correlation within a subject.  If this model fails to converge, a 
first-order autoregressive structure will be used instead; for this model, subject will be 
included as a random effect.  Contrasts will be used to obtain estimates of the treatment 
differences over 24 weeks (primary for EU/Canada; secondary for Japan/China; secondary 
for the US), over Weeks 12 to 24 (primary for Japan/China), and at Week 24 (primary for 
US).  Two-sided p values and point estimates with 2-sided 95% CIs will be produced for 
each treatment difference.  The primary analysis will be for the efficacy estimand.  
Secondary analyses will be produced for the attributable estimand.  The non-inferiority 
comparison of BFF MDI to Symbicort TBH will be based on the per-protocol estimand.  
Supportive analyses will:

Page 105 of 184 
• repeat the above analysis using the treatment policy estimand  
• provide estimates of the change from baseline at individual time points from the primary 
RM model 
 
Subgroup analyses for morning pre-dose trough FEV1 will be performed for the Japanese 
region versus the remaining regions combined.  Additional subgroup analyses may be 
defined in the Statistical Analysis Plan (SAP) as appropriate.   
Sensitivity analyses to evaluate the robustness of the primary analyses to the nature of the 
missing data are discussed in Section 9.15. 
9.4.2.2 
FEV1 AUC0-4 
Change from baseline in FEV1 AUC0-4 over 24 weeks will be analyzed in a similar manner as 
for morning pre-dose trough FEV1.  Area under the curve will be calculated using the 
trapezoidal rule and will be normalized by dividing by the time in hours from dosing to the 
last measurement included (typically 4 hours).  Only 1 non-missing, post dose value is 
required for the calculation of AUC.  Actual time from dosing will be used if available; 
otherwise scheduled time will be used. 
9.4.3 
Analysis of Secondary Endpoints 
The following variables appear as secondary for 1 or more registration approaches: peak 
FEV1, TDI focal score over 24 weeks, rescue Ventolin HFA usage over 24 weeks, SGRQ 
total score over 24 weeks, percentage of subjects achieving an MCID of 4 units or more in 
SGRQ total score at Week 24, RS-total score over 24 weeks, time to CID, the rate of 
moderate or severe COPD exacerbations, and time to onset. Multiplicity will be controlled 
for the secondary variables as described in Section 9.4.5.  The main analysis for secondary 
endpoints and other endpoints will use the efficacy estimand. The attributable estimand and 
treatment policy estimand will be estimated as sensitivity analyses for the secondary 
endpoints with the exception of time of onset on Day 1. The attributable estimand will 
impute missing data due to lack of efficacy and tolerability punitively, whereas all other 
missing data will be imputed using the observed data model. Details of imputation will be 
described in the SAP. The treatment policy estimand will include all post-treatment 
discontinuation data. 
9.4.3.1 
Transition Dyspnea Index 
Assessments of dyspnea will be obtained using the BDI/TDI.  The BDI/TDI questionnaire is 
presented in Appendix 9. 
At Visit 4, the severity of dyspnea at baseline will be assessed using the BDI.  At subsequent 
visits (as per Schedule of Events, Table 8) change from baseline will be assessed using the 
TDI.  The difference between treatment groups in TDI focal score over 24 weeks will be 
evaluated using a similar RM approach as for the primary endpoint, but using BDI instead of 
baseline FEV1 in the model, and adding baseline post-bronchodilator percent predicted FEV1

accordance with the user’s guide for the TDI score.  Two-sided p values and point estimates 
with 2-sided 95% CIs will be produced for each treatment difference.  The comparison of 
BFF MDI to Symbicort TBH will be for non inferiority rather than superiority and will use a 
margin of 0.75. 
The above analyses of the TDI focal score will be repeated over Weeks 12 to 24 as secondary 
efficacy for Japan/China.   
The difference between treatments at each of the individual visits will be evaluated and 
summarized, both for the focal score as well as for the individual components of the TDI: 
functional impairment, magnitude of task, and magnitude of effort.  Responder analyses will 
be performed, where responders are defined as a response of 1.0 point or more 
(corresponding to at least a minor improvement) on average over 24 weeks, and separately 
over Weeks 12 to 24.  Logistic regression will be used to compare the treatment groups with 
BDI, baseline eosinophil count, post-bronchodilator percent predicted FEV1, and percent 
reversibility to Ventolin HFA as continuous covariates, and treatment, and ICS use at 
Screening as categorical covariates.  P-values and odds ratios with 95% CIs will be produced 
for each treatment comparison. 
9.4.3.2 
Peak FEV1 
The peak change from baseline in FEV1 within 2 hours post-dosing over 24 weeks, over 
Weeks 12 to 24, and at Week 24 will be analyzed in a similar way to morning pre-dose 
trough FEV1. 
9.4.3.3 
St. George Respiratory Questionnaire 
The SGRQ is presented in Appendix 10.  The difference between treatment groups in the 
change from baseline in SGRQ over 24 weeks and over Weeks 12 to 24 will be evaluated 
using a similar RM approach as for the TDI focal score, but adding country as a covariate, 
and with baseline SGRQ replacing BDI in the model.  Scoring and handling of missing items 
will be conducted in accordance with the user’s guide for the SGRQ.  Each response is to be 
given a unique empirically derived weight between 0 and 100, the weights of all responses 
are then summed up and divided by the maximum possible score and expressed as a 
percentage.  Missing data of the SGRQ total score will not be imputed.  Two-sided p-values 
and point estimates with 2-sided 95% CIs will be produced for each treatment difference. 
As supportive analyses, the difference between treatments at each of the individual visits will 
be evaluated and summarized.  Individual domains of the SGRQ also will be analyzed in a 
similar fashion as the overall score.  A responder analysis will be performed where 
responders are defined as an improvement of 4.0 points or more on average at 24 weeks, over 
24 weeks, over Weeks 12-24, and at each post-randomization assessment time-point.  
Logistic regression will be used to compare the treatment groups with baseline SGRQ using a 
similar approach as the TDI responder analyses - with baseline eosinophil count, baseline 
post-bronchodilator percent predicted FEV1, and reversibility to Ventolin HFA as continuous

covariates, and treatment, country, and ICS use at Screening as categorical covariates.  P-
values and odds ratios with 95% CIs will be produced for each treatment comparison. 
9.4.3.4 
Rescue Ventolin HFA Use 
The number of puffs of rescue Ventolin HFA taken in the previous 12 hours will be recorded 
in the subject diary in the morning and evening.  The mean daily number of puffs of rescue 
Ventolin HFA will be calculated overall and for each of the 4-week intervals during the 
Treatment Period.  Diary data recorded during the last 7 days of the Screening Period will be 
used to calculate the baseline.  For every interval of time over which the mean number of 
puffs of rescue will be calculated for both overall as well as 4-week intervals, records with 
missing values will be ignored in both the numerator and denominator.  As such, the 
denominator will be adjusted based on the number of days (including half days) with non-
missing values.   
The difference between treatment groups in the change from baseline in rescue Ventolin 
HFA usage over 24 weeks will be evaluated using a similar RM approach as for the TDI.  
Instead of visit, the number of the relevant 4-week interval (Interval 1 to Interval 6) will be 
used as a categorical covariate in the model.  As supportive analyses, the treatment difference 
for each 4 week interval and over Weeks 12 to 24 will be evaluated and summarized.  
Additionally as supportive analyses, daytime rescue Ventolin HFA use and night-time rescue 
Ventolin HFA usage will be evaluated and summarized in a similar fashion.  Two sided p 
values and point estimates with 2-sided 95% CIs will be produced for each treatment 
difference. 
9.4.3.5 
RS-Total Score 
The EXACT is a 14-item PRO daily diary which will be used to measure the effect of 
treatment on exacerbations, and on the severity of respiratory symptoms.  The RS-total 
utilizes the 11 respiratory symptom items contained in the 14-item EXACT. The RS-Total 
score represents respiratory symptom severity, overall.  The mean change from baseline in: 
the RS-Total Score will be calculated over each 4-week interval of the 24-week Treatment 
Period.  The last 7 days of the Screening Period will be used to calculate the baseline.  The 
mean change from baseline in the RS-Total Score will be analyzed using a similar model 
as for the TDI to estimate treatment effects over 24 weeks, but using the baseline mean score 
instead of the BDI as a covariate, and baseline post-bronchodilator percent predicted FEV1 as 
a continuous covariate.  Instead of visit, the number of the relevant 4-week interval (Interval 
1 to Interval 6) will be used as a categorical covariate in the model.  This analysis will be 
secondary for the EU only. 
9.4.3.6 
COPD Exacerbations 
Secondary Endpoint Analysis: 
The rate of moderate or severe COPD exacerbations will be analyzed using negative 
binomial regression.  Chronic obstructive pulmonary disease exacerbations will be 
considered separate events provided that 7 or more days are between the recorded stop date

of the earlier event and start date of the latter.  Time at risk of experiencing an exacerbation 
will be used as an offset variable in the model.  Time during an exacerbation or in the 7 days 
following an exacerbation will not be included in the calculation of time at risk.  For 
moderate or severe COPD exacerbations, the start date is be defined as the start date of 
prescribed treatment with a systemic corticosteroid or systemic antibiotic and the stop date 
will be defined as the last day of prescribed treatment with a systemic corticosteroid or 
systemic antibiotic.  Treatments will be compared adjusting for country, baseline post-
bronchodilator percent predicted FEV1, baseline COPD exacerbation history, baseline 
eosinophil count, and ICS use at Screening. 
Other endpoints: 
The rate of COPD exacerbations of any severity and the rate of severe COPD exacerbations 
will be analyzed in a similar manner. 
The time to first moderate or severe COPD exacerbation, the time to the first COPD 
exacerbation of any severity, and the time to the first severe COPD exacerbation will each be 
analyzed using Cox regression model.  The model will include treatment; baseline percent 
predicted FEV1, baseline COPD exacerbation history, baseline eosinophil count, and ICS use 
at Screening.  Estimated adjusted hazard ratios relative to the comparator will be displayed 
along with the associated Wald 2-sided 95% CIs and p-values.  Time to first moderate or 
severe COPD exacerbation as well as the time to first COPD exacerbation of any severity 
will be displayed graphically for each treatment group using a Kaplan-Meier curve.  Subjects 
who did not experience a COPD exacerbation will be censored at the Week 24 visit.  
Subjects who withdrew from the study without experiencing a COPD exacerbation will be 
censored at the date of withdrawal. 
Duration of COPD Exacerbation 
For moderate or severe exacerbations, the duration is defined by the length of prescribed 
treatment, whereas for mild exacerbations, the duration is defined by the length of symptoms. 
For moderate or severe COPD exacerbations, the start date will be defined as the start date of 
prescribed treatment with a systemic corticosteroid or systemic antibiotic and the stop date 
will be defined as the last day of prescribed treatment with a systemic corticosteroid or 
systemic antibiotic.  In order to ensure that the same event is not counted twice, concurrent 
moderate or severe COPD exacerbations with start and stop dates equal to or less than 7 days 
apart will be considered the same event and assigned the maximum severity between the two.   
For mild COPD exacerbations, start date will be defined as the onset of worsened symptoms 
as recorded by the subject in the eDiary, and the stop date will be defined as the last day of 
worsened symptoms.  In order to ensure that the same event is not counted twice, mild COPD 
exacerbations with start and stop dates equal to or less than 7 days apart will be considered 
the same event.   
In addition, in order to not double count exacerbations that are moderate or severe, eDiary 
data from dates within 7 days of a moderate or severe exacerbation will not be included as

additional mild COPD exacerbations.  This implies that continuing worsened symptoms that 
meet the definition of a mild exacerbation would need to be present at least 2 days prior to 
the 7-day period immediately preceding the start date of a moderate or severe COPD 
exacerbation in order to be considered a separate event.  Similarly, worsened symptoms 
would need to be present for at least 2 days after the 7-day period immediately following a 
moderate or severe COPD exacerbation to be considered a separate event.   
Analyses of each severity of exacerbation will account for the time that subjects are at risk of 
having an exacerbation of that severity or greater.  Time during or immediately following an 
exacerbation will not be considered as part of the time that the subject was at risk.  However, 
time during or immediately following an exacerbation of lower severity will be included 
since, for example, a subject experiencing a mild exacerbation is still at risk of the event 
increasing in severity and becoming a moderate exacerbation. 
9.4.3.7 
Time to Clinically Important Deterioration 
CID is defined as a ≥ 100 mL decrease (from baseline) in trough FEV1, or ≥ 4 points increase 
(from baseline) in SGRQ total score, or a TDI focal score of -1 point or less, or treatment-
emergent moderate-or-severe COPD exacerbation occurring up to Week 24. Sustained CID is 
defined as ≥ 100 mL decrease (from baseline) in trough FEV1, or ≥ 4 points increase (from 
baseline) in SGRQ total score, or a TDI focal score of -1 point or less, any of which is 
occurring on two consecutive analysis visits or for ≥ 50% of all available subsequent analysis 
visits, or a treatment emergent moderate-or-severe COPD exacerbation occurring up to Week 
24.  
Time to CID analysis will be performed using the Cox regression model. The model will 
include baseline post-bronchodilator percent predicted FEV1, baseline eosinophil count, 
baseline COPD exacerbation history (0, 1, ≥2), country, and ICS use at Screening (yes/no). 
Time to a CID event will be based on the component event which occurs first. Subjects who 
do not have a CID event will be censored at the earliest day among the component censoring 
times. COPD exacerbations happening after Week 24 will not be counted as CID events. 
Estimated adjusted hazard ratios will be displayed along with associated 95% CI and p-
values. Time to CID will be displayed for each treatment group using a Kaplan-Meier curve. 
Time to CID will be presented for the efficacy, the attributable, the treatment policy, and per-
protocol estimands.  
The analyses will be repeated for time to sustained CID as an ‘other’ endpoint for the 
efficacy estimand. 
9.4.3.8 
Time to Onset of Action 
The onset of action will be determined for each treatment using the post dosing FEV1 
assessments from Day 1.  The onset of action for each product (BGF MDI, GFF MDI, and 
BFF MDI) will be defined as the first time point where the mean change from baseline 
exceeds 100 mL.  Supportive analyses may be conducted using alternatively definitions of 
onset of action.

Analysis of Other Endpoints 
All exploratory endpoints will be presented for the efficacy estimand only. These will not be 
presented for the attributable, treatment policy, or per-protocol estimands.  
9.4.4.1 
Other Spirometry Endpoints 
The analysis of the other between-treatment comparisons for changes in morning pre-dose 
trough FEV1 at each post-dose time point has already been described in Section 9.4.2.1.  
Treatment differences in the change from baseline in FEV1, morning pre-dose trough FVC, 
PEFR, and FEF25-75 will be evaluated in a similar manner to the primary endpoint. 
9.4.4.2 
12-Hour Pulmonary Function Tests 
FEV1 AUC0-12 will be measured in a subset of subjects at the 12 week visit.  Area under the 
curve will be calculated using the trapezoidal rule and transformed into a weighted average 
by dividing by the time in hours from dosing of the last measurement included (typically 12 
hours).  Only 1 non-missing post dose value is required for the calculation of AUC.  The per 
protocol estimand is primary for the non-inferiority comparison of BFF vs. Symbicort. 
Actual time from dosing will be used if available; otherwise scheduled time will be used.  
The differences between treatment groups in FEV1 AUC0-12 at Week 12 will be evaluated 
using an ANCOVA with baseline FEV1, baseline eosinophil count, and percent reversibility 
to Ventolin HFA as continuous covariates, and treatment, and ICS use at Screening as 
categorical covariates.  Two-sided p-values and point estimates with 2-sided 95% CIs will be 
produced for each treatment difference.  The comparison of BFF MDI to Symbicort TBH 
will be for non-inferiority rather than superiority and will use a margin of 75 mL. 
As additional supportive analyses, FEV1 AUC0-4, FEV1 AUC0-6, FEV1 AUC6-12, FVC 
AUC0-4, FVC AUC0-4, PEFR AUC0-12, PEFR AUC0-4, and FEF25-75 AUC0-12, FEF25-75 AUC0-4 
will be calculated and analyzed for the efficacy estimand only, in a similar fashion as the 
efficacy estimand for FEV1 AUC0-12. 
9.4.4.3 
Percentage of Days with No Rescue Ventolin HFA Use over the Treatment 
Period 
As a supportive analysis, the percentage of days with ‘no rescue Ventolin HFA use’ over 24 
weeks will be analyzed.  A ‘day with no rescue use’ is defined as any day where the subject 
reported zero puffs of rescue Ventolin HFA.  The rescue Ventolin HFA usage diary data 
from days where rescue Ventolin HFA usage data is non-missing will be used to ascertain the 
days with “no rescue Ventolin HFA use”.  The percentage of days with ‘no rescue Ventolin 
HFA use’ will be summarized by treatment and analyzed using ANCOVA with baseline 
average daily rescue Ventolin HFA use instead of baseline FEV1 as a covariate, and baseline 
post-bronchodilator percent predicted FEV1 as a continuous covariate.

Time to Treatment Discontinuation 
Treatment discontinuation will be defined as a moderate or severe COPD exacerbation or 
discontinuation from treatment for any reason.  The time to treatment discontinuation will be 
analyzed using a Cox regression model.  The model will include treatment, baseline post-
bronchodilator percent predicted FEV1, baseline eosinophil count, baseline COPD 
exacerbation history, and ICS use at Screening.  Estimated adjusted hazard ratios will be 
displayed along with associated 95% CIs and p-values.  Time to treatment discontinuation 
will be displayed graphically for each treatment group using a Kaplan-Meier curve.  Subjects 
who did not experience a treatment discontinuation will be censored at Week 24.

Exacerbations of Chronic Pulmonary Disease Tool 
The EXACT (please note new name Section 7.1.4.5) is a 14-item PRO daily diary which will 
be used to measure the effect of treatment on exacerbations, and on the severity of respiratory 
symptoms.  The severity of respiratory systems will be measured using the E-RS:COPD, 
which is an 11-item subset of the EXACT.  The analysis of the RS-Total score is already 
described under secondary endpoints.  Mean change from baseline in: the daily EXACT 
Total Score, and the 3 subscale scores of the E-RS:COPD (i.e. RS-Breathlessness, RS-Cough 
and Sputum, and RS-Chest Symptoms) will be calculated over each 4-week interval of the 
24-week Treatment Period and analyzed using a similar approach as the RS-Total score.  The 
last 7 days of the Screening Period will be used to calculate the baseline. 
9.4.4.6 
European Quality-of-Life-5 Dimension-5 Level Questionnaire 
The European Quality-of-Life-5 Dimension-5 Level Questionnaire (EQ-5D-5L) data will be 
weighted to calculate an index score based upon subjects responses to the 5 dimensions.  The 
visual analogue scale will be scored from 0 (worst imaginable health state) through 100 (best 
imaginable health state) to represent the subject’s self-report concerning how bad or how 
good their health was during that day.  The percentage of subjects’ categorical responses to 
each of the 5-dimensions will be summarized.  Descriptive statistics for the index score and 
VAS will be presented by treatment group.  VAS scores over 24 weeks may be analyzed 
using a similar RM model as is used for the TDI, but using baseline EQ-5D-5L VAS score as 
a covariate instead of BDI. 
The compliance of completing the EQ-5D-5L questionnaires will be described at each 
assessment time-point, by the number and percentage of subjects who filled out a 
questionnaire (per subject, at least 1 question answered). 
9.4.5 
Control of Type I Error 
There are 3 separate plans for control of Type I error, corresponding to each of the 3 
registration approaches for Japan/China, EU/Canada, and US.  Each of the plans will test the 
primary endpoint (s) using the efficacy estimand first for superiority comparisons, followed 
by the attributable estimand as the first secondary.  Additional secondary endpoints will only 
be tested using the efficacy estimand for Type I error control.  Non-inferiority comparisons 
will be made using the per-protocol estimand.  Additional details, including non-inferiority

margins, will be described in detail in the SAP.  All secondary endpoints with the exception 
of time to onset are included in the Type I error control plans described below. 
9.4.5.1 
Japan/China Approach:  
The comparisons of interest for the Japan/China approach are BGF MDI versus BFF MDI 
and BGF MDI versus GFF MDI, both for superiority, and BFF MDI versus Symbicort TBH 
for non-inferiority. 
Strong control of the Type I error rate will be maintained at the 2-sided 0.05 level for the 
primary endpoint across key treatment comparisons using a sequential approach across 
comparisons, and then for the secondary measures.  Type I error control will be maintained 
within comparison using a combination of sequential and simultaneous approaches as 
detailed below.  Based on positive dependence of the test statistics (Sarkar, 2008; Sarkar and 
Chang 1997), simultaneous control of Type I error for the relevant secondary measures will 
be achieved using the Hochberg procedure (Hochberg, 1988).   
The following 3 between-treatment comparisons will be conducted, in the order stated, for 
morning pre-dose trough FEV1 over Weeks 12 to 24: BGF MDI versus BFF MDI, BGF MDI 
versus GFF MDI, using the efficacy estimand, and BFF MDI versus Symbicort TBH (non-
inferiority) using the per-protocol estimand.  Each comparison will be made only if the 
preceding comparison in the sequence is statistically significant.   
If the comparisons for BGF MDI versus BFF MDI and BGF MDI versus GFF MDI are both 
statistically significant at a 2-sided alpha level of 0.05, testing will proceed to comparison of 
the respective attributable estimands in the same order. If the comparisons of the attributable 
estimands are also significant, then the remaining secondary measures within each 
comparison will be tested using the efficacy estimand.  Type I error will be controlled at 0.05 
within each comparison (BGF MDI versus BFF MDI, BGF MDI versus GFF MDI) for the 
secondary endpoints through simultaneous testing under the Hochberg procedure with a 2-
sided alpha of 0.05. 
If non-inferiority is established for the comparison of trough FEV1 between BFF MDI and 
Symbicort TBH, then tests of the additional secondary measures for this comparison will be 
interpreted without any additional control of Type I error. 
9.4.5.2 
EU/Canada Approach 
The comparisons of interest for the EU/Canada approach are: BGF MDI versus GFF MDI, 
BGF MDI versus BFF MDI, and BGF MDI versus Symbicort TBH, all for superiority, and 
the comparison of BFF MDI vs. Symbicort for non-inferiority.  All comparisons are 
evaluated over 24 weeks unless stated otherwise. 
Strong control of the Type I error rate will be maintained at the 2-sided 0.05 level for the key 
comparisons using a sequential approach for the primary endpoints and then for the 
secondary measures Type I error control will be maintained within comparison using a 
combination of sequential and simultaneous approaches as detailed below.

The following 4 comparisons will be conducted first, in the order they appear below: 
• FEV1 AUC0-4 for BGF MDI versus BFF MDI using the efficacy estimand 
• Trough FEV1 for BGF MDI versus GFF MDI using the efficacy estimand 
• FEV1 AUC0-4 for BGF MDI versus BFF MDI using the attributable estimand 
• Trough FEV1 for BGF MDI versus GFF MDI using the attributable estimand 
 
All subsequent comparisons below will use only the efficacy estimand. 
If the comparison of FEV1 AUC0-4 between BGF MDI and BFF MDI using the attributable 
estimand above is statistically significant, testing will proceed to the secondary comparison 
of BGF MDI versus BFF MDI for change in morning pre-dose trough FEV1 using a 2-sided 
0.05 level test.  If this test is also significant, testing will proceed to the remaining secondary 
endpoints.  BGF MDI versus BFF MDI will be simultaneously compared among these 
secondary endpoints using the Hochberg procedure with a 2-sided alpha of 0.05.  
If the comparison of BGF MDI versus GFF MDI for change in morning pre-dose trough 
FEV1 using the attributable estimand is statistically significant, testing will proceed to the 
remaining secondary endpoints for BGF MDI vs. GFF MDI using the efficacy estimand.  
BGF MDI versus GFF MDI will be simultaneously compared among the secondary 
endpoints using the Hochberg procedure with a 2-sided alpha of 0.05. 
If the comparison of FEV1 AUC0-4 for BGF MDI versus BFF MDI is statistically significant 
using the attributable estimand, testing will also proceed to a comparison of BGF MDI versus 
Symbicort TBH for of FEV1 AUC0-4 using the efficacy estimand.  If statistically significant, 
the remaining secondary endpoints for BGF MDI versus Symbicort TBH will be 
simultaneously compared among the secondary endpoints using the Hochberg procedure with 
a 2-sided alpha of 0.05. 
Finally, if the comparison of FEV1 AUC0-4 over 24 weeks for BGF MDI versus BFF MDI is 
statistically significant, testing will proceed to the non-inferiority comparisons of BFF MDI 
versus Symbicort TBH.  If non-inferiority is established, tests of the additional secondary 
measures for this comparison will be interpreted without any additional control of Type I 
error. 
9.4.5.3 
US Approach  
The comparisons of interest for the US approach are: BGF MDI versus GFF MDI and BGF 
MDI versus BFF MDI, both for superiority, and at Week 24 unless stated otherwise. 
Statistical significance for nominal comparisons will be at alpha=0.05. 
Strong control of the Type I error rate will be maintained at the 2-sided 0.05 level for the key 
comparisons using a sequential approach for the primary endpoints and then for the 
secondary measures Type I error control will be maintained within comparison using a 
combination of sequential and simultaneous approaches as detailed below .

• Trough FEV1 for BGF MDI versus GFF MDI using the attributable estimand 
 
If the comparison of FEV1 AUC0-4 between BGF MDI versus BFF MDI using the 
attributable estimand is statistically significant, the secondary endpoints for BGF MDI versus 
BFF MDI will be compared simultaneously using the efficacy estimand, and using the 
Hochberg procedure with a 2-sided alpha of 0.05. 
If the comparison of trough FEV1 AUC0-4 between BGF MDI versus GFF MDI for the

Subgroup analyses for primary and secondary endpoints will be performed for the Japanese 
region versus the remaining regions combined as well as for Chinese and Asian subgroups.  
Additional subgroup analyses will be defined in the SAP as appropriate.

Safety Analyses 
9.6.1 
Adverse Events 
The version of the Medical Dictionary for Regulatory Activities (MedDRA) that is current at 
the time of database lock will be used to code verbatim terms for AEs for final analysis of the 
data.  The number and incidence of adverse events, serious adverse events, adverse events of 
special interest by category, confirmed AEs of pneumonia, and study drug discontinuations 
due to adverse events will be summarized by treatment group.  They will be tabulated at the 
level of the Medical Dictionary for Regulatory Activities (MedDRA) preferred term and the 
MedDRA system organ class.  Tabulations will be broken down by severity, by relationship 
to study drug, and AEs leading to treatment discontinuation.  No hypothesis tests will be 
performed. 
9.6.2 
Cardio- and Cerebrovascular Events Determined by Clinical Endpoint 
Committee 
The CEC will review and adjudicate serious CCV events as MACE.  MACE events are 
defined as the following: 
• Cardiovascular death 
• Non-fatal myocardial infarction (MI)

• Non-fatal stroke  
 
The CEC will review and assess these non-fatal serious CCV events and all deaths as to 
whether or not they fulfill criteria (based on CEC working practices) for MACE. 
MACE events will be summarized by treatment group. 
9.6.3 
Pneumonia Events Determined by Clinical Endpoint Committee 
All AEs/SAEs with preferred terms that could relate to pneumonia will be adjudicated to 
provide a more complete assessment of all physician-reported pneumonias.  The assessment 
of pneumonia events will include the overall rates of pneumonia. 
In order to account for specific patient risk factors, time to first pneumonia will be compared 
between treatments using Cox proportional hazards.  Specific patient risk factors that have

baseline assessment (Day 1) and for the pre-dose value and change from baseline at pre dose 
value of post-baseline visits with scheduled lab assessments of continuous laboratory 
variables, including serum potassium and glucose will be tabulated. 
Shift tables relative to the normal reference ranges will be produced using the categories 
defined by the CTCAE Version 4.03 grades.  For these shift tables, for each treatment, the 
subject’s pre-dose grade will be cross-tabulated by the subject’s maximum post baseline 
grade during the treatment; also, the subject’s maximum post-baseline grade during treatment 
will be tabulated for all baseline grades combined. 
The number and percent of subjects with potentially clinically significant (PCS) lab values 
will be summarized.  Potentially clinically significant values for serum potassium are <3.0 
mmol/L or >6.0 mmol/L, and for blood glucose <2.2 mmol/L or >13.9 mmol/L.  Potentially 
clinically significant values for additional labs will be defined in the SAP.  No hypothesis 
tests will be performed. 
9.6.5 
Vital Signs 
Summary statistics (mean, median, standard deviation and range) for absolute values and 
change from baseline values will be tabulated for each treatment and assessment time.  For 
vital signs, baseline values will be defined as the average of the values prior to dosing at the 
randomization visit (Visit 4).  Potentially clinically significant values for vital signs will be 
defined in the SAP and the percentage of subjects with PCS values will be summarized.  No 
hypothesis tests will be performed.

Electrocardiograms 
Summary statistics (mean, median, standard deviation and range) for raw values and change 
from baseline values in Heart Rate, PR Interval, QRS Axis, QRS Interval, QT Interval and 
QTcF interval will be calculated, where baseline is defined as the average of the pre-dose 
measurements taken prior to the start of treatment at the randomization visit (Visit 4).  The 
QTcF (Fridericia Corrected QT) is defined as (QT/[RR1/3]).  Heart rate (bpm) is estimated as 
60,000/RR.  These assessments will be tabulated for each treatment and assessment time.  
Potentially clinically significant values for ECG parameters will be defined in the SAP, and 
the percentage and number of subjects with PCS ECG values will be tabulated.  No 
hypothesis tests will be performed. 
9.6.7 
Exposure 
The duration of exposure to study medication (in days), the person-years of exposure, the 
mean number of doses, and number and percentage of subjects who are compliant will be 
summarized by treatment group.  All exposure summaries will be generated for the safety 
population by actual treatment received. 
9.7 
Pharmacokinetic Analyses 
Non-compartmental parameter estimates for budesonide, glycopyrronium, and formoterol 
AUC0-12 and Cmax will be natural-log transformed and analyzed using mixed effect models.  
Additional analyses will estimate bioavailability of BGF MDI relative to GFF MDI, BFF 
MDI, or Symbicort TBH.  Separate mixed models with fixed effects for treatment, visit and 
treatment-by-visit interaction and a random effect for subject will be fit for each analyte. 
9.8 
HPA Axis 
The primary analysis will performed on the log transformed ratio from baseline of the serum 
cortisol weighted mean (0-24 h) for subjects in the HPA Axis Population.  Baseline was 
defined as the weighted mean 0-24 h from Day -1/1.  An analysis of covariance (ANCOVA) 
model was fitted with baseline (log transformed), gender, age, and treatment group as terms 
in the model and the following comparisons will be made: BGF MDI versus GFF MDI, BGF 
MDI versus BFF MDI, and Symbicort TBH versus GFF MDI.  The change from Screening 
(Visit 3) to Visit 10a (Week 24) in the 0- to 24-hour weighted mean SC at Week 24 will also 
be summarized by treatment group.  Serum cortisol profiles over 24 hours will be graphically 
presented by treatment group using box plots over time, at baseline and at Week 24. 
The percentage of subjects observing a 30% or greater reduction from baseline in the 0-24 
hour weighted mean SC will be summarized.

9.10 Randomization 
Subjects will be randomized in a 2:2:1:1 scheme.  Approximately 600 subjects each will be 
randomized to the BGF MDI and GFF MDI treatment groups, and 300 subjects each will be 
randomized to the BFF MDI and Symbicort TBH treatment groups.  Randomization will be 
stratified by reversibility (yes/no) to Ventolin HFA, country, and disease severity as 
determined by post-bronchodilator percent predicted FEV1 (≥50%=moderate versus 
<50%=severe or very severe) to ensure even distribution of treatment arms within each 
stratum. 
9.11 Experimental Design 
This study is a multi-center, double-blind, parallel-group, active-controlled (open-label 
Symbicort TBH) design. 
9.12 Sample Size 
It is estimated that a sample size of 1800 subjects (600 per arm in the BGF MDI and GFF 
MDI groups and 300 per arm in the BFF MDI and Symbicort TBH groups) will provide the 
following power estimates, all assuming Type I error control at a 2-sided alpha level of 0.05 
unless specified otherwise: 99% power to detect a difference of 75 mL between BGF MDI 
and BFF MDI in FEV1 AUC0-4 over 24 weeks; 96% power to detect a difference of 35 mL 
between BGF MDI and GFF MDI in morning pre-dose trough FEV1 over 24 weeks and 
approximately 92% power over Weeks 12 to 24; 97% power to detect a difference of 50 mL 
between BGF MDI and BFF MDI in morning pre-dose trough FEV1 over Weeks 12 to 24; 
and 96% power to demonstrate non-inferiority of BFF MDI to Symbicort TBH in morning 
pre-dose trough FEV1 over 24 weeks and approximately 92% power over Weeks 12 to 24 
based on a margin of 50 mL (one-sided, alpha=0.025) assuming no true difference.   
Assumptions regarding variability for the primary endpoint are based on Pearl’s experience 
with Phase IIb and III clinical studies.  A composite value standard deviation (SD) of 200 mL 
for the change from baseline at each visit has been assumed for trough FEV1 and 220 mL for 
FEV1 AUC0-4.  Dropout is anticipated to be approximately 12% by the end of the study.  
Based on the repeated measures analysis, an effective SD for the change over 24 weeks of 
157 mL and 173 mL for trough FEV1 and FEV1 AUC0-4, respectively, is assumed.  For 
Weeks 12 to 24, an effective SD for trough FEV1 of 171 mL is assumed. 
9.13 Data Validation and Transformation 
In general the distribution of spirometry measures is well-approximated by a normal 
distribution.  Under some circumstances, however, (for example during a COPD 
exacerbation, unrelated to treatment) extreme and atypical values can arise.  Such values 
have high influence on estimation of variance parameters and on standard errors of fixed 
effect estimates.  The distribution and potential influence of outliers will be evaluated and 
additional sensitivity analyses will be conducted if warranted to demonstrate the robustness 
of the primary and secondary results.

9.14 Analysis Plan 
All analyses will be specified in a detailed SAP that will be accompanied by table and data 
listing shells with mock graphical representations.  The analysis plan will be approved by 
signature before database lock and unblinding.  
9.15 Handling of Missing Data 
All observed values will be included in the treatment policy estimand.  All observed values 
recorded prior to treatment discontinuation will be included in the efficacy estimand.  As a 
maximum likelihood method, RM is valid for missing-at-random (MAR) data (Little and 
Rubin, 2002).  Additional sensitivity analyses will be performed using multiple imputations 
under varying assumptions about treatment effects in the unobserved data to explore the 
impact of missing data.  Further details are provided in the SAP. 
Change from baseline in morning pre-dose trough FEV1 at each visit is defined as the 
average of the 60 and 30 minute pre-dose values minus baseline.  In subjects missing either 
of these pre-dose assessments, the value will be calculated from the single measurement.  In 
subjects missing both pre-dose values, morning pre-dose trough FEV1 at that visit will not be 
calculated. 
Peak FEV1 and FEV1 AUC0-4 will be included in the efficacy, attributable, treatment policy, 
and per-protocol estimands as long as there is at least 1 non-missing post-dose value during 
the first 4 hours post-dose. 
For the subset of subjects included in the 12-hour spirometry assessment at Visit 10a (Week 
24), the efficacy estimand will use all available data with the trapezoidal rule to calculate 
AUC0-12 (AUC0-6 and AUC6-12) using change from baseline values.  The determination of 
peak change from baseline in FEV1 requires at least 1 non-missing FEV1 value during the 
first 2 hours post-dose. 
9.16 Statistical Software 
Data processing, statistical screening, descriptive reporting and analysis of the efficacy and 
safety data will be performed using SAS (Version 9.2 or higher).  Graphs may also be 
produced using R (R Development, 2003).

10.8 Study Monitoring 
In accordance with applicable regulations, GCP, and Pearl procedures, clinical monitors will 
contact the site prior to subject enrollment to review the protocol and data collection 
procedures with site staff.  In addition, the monitor will periodically contact the site, 
including conducting on-site visits.  The extent, nature, and frequency of on-site visits will be 
based on such considerations as the study objective and/or endpoints, the purpose of the 
study, study design complexity, and enrollment rate. 
During these contacts, the monitor will: 
• Check the progress of the study. 
• Review study data collected.   
• Conduct source document verification. 
• Identify any issues and address their resolution. 
 
This will be done in order 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 
amendments), GCP, and all applicable regulatory requirements. 
 
The Investigator agrees to allow the monitor direct access to all relevant documents and to 
allocate his/her time and the time of his/her staff to the monitor to discuss findings and any 
relevant issues. 
Upon completion of the study, the monitor will conduct the following activities in 
conjunction with the Investigator or site staff, as appropriate: 
• Return of all study data to Pearl  
• Data queries  
• Accountability, reconciliation, and arrangements for unused investigational product(s)

assurance auditors and by all applicable regulatory authorities.  The period of time these 
documents must be maintained is governed by applicable regulations.  Pearl or its designee 
will inform the Investigator when these documents may be destroyed.  Pearl or its designee 
must be notified in writing at least 6 months prior to the intended date of disposal of any 
study record related to this protocol to allow Pearl to make alternate storage arrangements. 
10.10 Financial Disclosure 
The Principal Investigator or sub-Investigators named on the FDA Form 1572 or the locally 
accepted alternate Investigator Statement form, will need to complete a financial disclosure 
form prior to study initiation, at any time during the study execution if new information 
needs to be disclosed, and for 1 year after study completion.  Investigators should make the 
IRB/IEC aware of any financial interests that the Investigator has in the investigational 
product. 
10.11 Investigator’s Final Report 
Shortly after completion of the Investigator's participation in the study, the Investigator will 
submit a written report to Pearl. 
10.12 Publication Policy 
Pearl intends to publish the results of all of the clinical studies that it sponsors in compliance 
with the Declaration of Helsinki (http://www.wma.net/en/10home/index.html).  Consistent 
with the recommendations of the editors of several leading medical journals, the International 
Committee of Medical Journal Editors (ICMJE), authorship of publications resulting from 
Pearl -sponsored studies should fairly recognize the activities of those that have made a 
significant contribution to the study.  Thus, it is anticipated that authorship will reflect the 
contribution made by Pearl personnel, the Investigators and others involved, such as 
statisticians. 
In recent years, issues about conflicts of interest and accuracy of the study data have been 
raised in the medical press.  Accordingly, Pearl has developed publication guidelines as 
described below: 
1. Responsibility: Each Principal Investigator is responsible for the accuracy and 
completeness of all data from their site.  Pearl (or its representatives) is responsible for 
the accuracy of the data entered into the study databases and for the accuracy of the 
analyses conducted. 
2. Authorship and Publication Committee: The Sponsor, in collaboration with the 
Investigators, will establish the appropriate authorship and responsibility for drafting 
study documents in accordance with the principles of the ICMJE and the International 
Society for Medical Publication Professionals. It is anticipated that a publication 
committee will be formed to assume oversight of these activities. All manuscripts will be 
reviewed and agreed upon before submission for publication by all authors. 
3. Sponsor Review of External Manuscripts: Consistent with the previous bullet point, 
drafts of any and all publications or presentations that may arise from this study must be 


Budesonide, Glycopyrronium, and Formoterol Fumarate Inhalation Aerosol

submitted at least 30 days prior to submission for publication or presentation to Pearl for 
review, approval, and to ensure consistency with the policy in this protocol.  Pearl will 
have the right to request appropriate modification to correct facts and to represent its 
opinions, or the opinions of the publication committee, if these differ with the proposed 
publication. 
4. Confidentiality: Investigators will conduct all interactions with Pearl and with third 
parties consistent with the executed confidentiality agreements.  While publication, by 
intention, presents the critical scientific data in a public forum, some information (such as 
future plans, results of nonclinical studies, or chemical formulae) may still need to remain 
confidential. 
5. Medical Journal Review: Consistent with the intention of Pearl to publish the study in a 
fair and accurate manner, Pearl supports diligence in the publication review process of 
medical journals.  Accordingly, upon request, all pertinent study data and information 
will be made available as supplemental information for journal editors and reviewers to 
evaluate and audit, e.g., protocol and amendments, data tabulations.  The journal and 
reviewers will need to make arrangements to maintain the confidentiality of such 
supplemental information, where relevant, and Pearl will make suitable arrangements to 
ensure that the identity of journal reviewers is kept confidential.  Records will be 
maintained of reviewers and the respective documents and datasets that were reviewed by 
each of them. 
6. Reporting of Clinical Trial Results: To provide transparency in the conduct and 
reporting of randomized clinical trials, Pearl reports clinical findings based on the 
guidance of The CONSORT (Consolidated Standards of Reporting Trials) Statement 
(CONSORT, 2010) and a 25 item checklist which is intended to improve the reporting of 
a randomized controlled Study, and to facilitate reader understanding of the Study design, 
conduct, analysis and interpretation, and to support their ability to assess the validity of 
its results. 
7. Internet Clinical Trial Listing: In addition, also consistent with the recommendations of 
the ICMJE, Pearl will make available appropriate information regarding the study via the 
internet.  This will include registration and listing of the study on www.clinicaltrials.gov, 
the US National Institutes of Health listing of clinical trials, and other clinical trial 
listings as appropriate (e.g., EUdraCT; https://eudract.ema.europa.eu).  Per AstraZeneca 
policy, Pearl posts clinical study protocols for public viewing when a manuscript is 
published in a medical journal.  Prior to being made public, the protocol is reviewed by 
AstraZeneca Intellectual Property.

Subject Instructions for Use of  BGF MDI, GFF MDI, 
and BFF MDI 
How do I store the inhaler? 
• The inhaler should be stored below 25°C (77°F) in a dry place.  Excursions permitted up 
to 30°C (86°F).   
• The contents of the canister are under pressure.  Do not puncture or throw the canister 
into a fire or incinerator.  Do not use or store it near heat or open flame.  Storage above 
120ºF may cause the canister to burst. 
• Keep the product and all medicines out of the reach of children. 
 
For Oral Inhalation Only 
Parts of the Inhaler: 
• The parts of your inhaler are seen in Figure 1. 
 
Figure 1 
 
 
• The Dose indicator lets you know about how many puffs are left in your inhaler and is 
the part of the inhaler that is pressed to dispense a puff of medication.  See Figure 1. 
• The Dose indicator should be pointing just to the right of 120 when your inhaler is new.  
See Figure 1. 
• The Dose indicator has numbers for every 20 puffs.  The Dose indicator display will 
move after every tenth puff.

• For example, if the Dose indicator is pointing to 120 (see Figure 2a) and you take 10 
puffs it will move between 120 and 100.  This means that there are 110 puffs of medicine 
left (see Figure 2b).  After 10 more puffs are used, the Dose indicator pointer will move 
to the number 100.  This means that there are 100 puffs of medicine left (see Figure 2c). 
• The Dose indicator number will continue to change after every 20 puffs. 
• When the number in the Dose indicator window changes to 20 and the color behind the 
number changes to red, this means that there are only 20 puffs left in your inhaler.  See 
Figure 2d. 
 
Figure 2 
 
Preparing the Inhaler for Use: 
The inhaler comes in a foil pouch that contains a drying packet (desiccant). 
• Take the inhaler out of the foil pouch. 
• Throw away the pouch and the drying packet.  Do not eat or inhale the contents of the 
drying packet.   
• Remove the Cap from the Mouthpiece as shown in Figure 3.   
 
Figure 3 
 
Prime the inhaler before you use it for the first time.

Priming the Inhaler: 
• Check inside the Mouthpiece for objects before use. 
• Hold the Actuator with the Mouthpiece pointing away from you and others as shown in 
Figure 4a. 
• Shake the inhaler well before each puff. 
• Push down fully on the center (not ‘off center’) of the Dose indicator on top of the 
Canister (see Figure 1) until the Canister stops moving in the Actuator to release a 
puff from the Mouthpiece as shown in Figure 4b.  Note: It is normal to hear a soft click 
from the dose indicator as it counts down during use. 
• Repeat this priming step 3 more times for a total of 4 times, shaking the inhaler each time 
before you press it. 
• After completing the 4 priming puffs, your inhaler is now primed ready to use for the first 
time. 
You must re-prime your inhaler again if you have not used it in more than 7 days.  Take the 
cap off the mouthpiece and shake and spray the inhaler 2 times into the air away from your 
face. 
Figure 4 
 
 
Using the Inhaler: 
Your dose of medicine comes from 2 puffs from the inhaler. 
Refer to Figure 5 for Step 1 through Step 8. 
• Step 1: Remove the Cap from the Mouthpiece. 
• Step 2: Shake the inhaler well before each puff. 
• Step 3: While holding the inhaler with the Mouthpiece pointing towards you breathe out 
through your mouth to empty as much air from your lungs as possible.

Instructions for Use of Symbicort® Turbuhaler® 
Inhalation Powder Device 
Preparing your new Symbicort Turbohaler 
Before using your new Symbicort Turbohaler for the first time, you need to prepare it for 
use as follows: 
• Unscrew the cover and lift it off.  You may hear a rattling sound. 
• Hold your Turbohaler upright with the red grip at the bottom. 
• Turn the red grip as far as it will go in one direction.  Then turn it as far as it will go in 
the other direction (it does not matter which way you turn it first).  You should hear a 
click sound. 
 
 
• Do this again, turning the red grip in both directions. 
• Your Turbohaler is now ready for use. 
 
How to take an inhalation 
Every time you need to take an inhalation, follow the instructions below. 
1. Unscrew the cover and lift it off.  You may hear a rattling sound. 
2. Hold your Turbohaler upright with the red grip at the bottom.   
3. Do not hold the mouthpiece when you load your Turbohaler.  To load your Turbohaler 
with a dose, turn the red grip as far as it will go in one direction.  Then turn it as far as it 
will go in the other direction (it does not matter which way you turn it first).  You should 
hear a click sound.  Your Turbohaler is now loaded and ready to use.  Only load your 
Turbohaler when you need to use it.   
4. Hold your Turbohaler away from your mouth.  Breathe out gently (as far as is 
comfortable).  Do not breathe out through your Turbohaler.   
5. Place the mouthpiece gently between your teeth.  Close your lips.  Breathe in as deeply 
and as hard as you can through your mouth.  Do not chew or bite on the mouthpiece.

6. Remove your Turbohaler from your mouth.  Then breathe out gently. 
The amount of medicine that is inhaled is very small.  This means you may not be able to 
taste it after inhalation.  If you have followed the instructions, you can still be confident 
that you have inhaled the dose and the medicine is now in your lungs. 
 
7. If you are to take a second inhalation, repeat steps 2 to 6.   
8. Replace the cover tightly after use.   
9. Rinse your mouth with water after your daily morning and/or evening doses, and spit it 
out.   
Do not try to remove or twist the mouthpiece.  It is fixed to your Turbohaler and must not be 
taken off.  Do not use your Turbohaler if it has been damaged or if the mouthpiece has come 
apart from your Turbohaler. 
Cleaning your Turbohaler  
Wipe the outside of the mouthpiece once a week with a dry tissue.  Do not use water or 
liquids. 
How to store Symbicort Turbohaler  
• Keep this medicine out of the sight and reach of children.   
• Do not use this medicine after the expiry date that is stated on the carton or on the label 
of your inhaler after EXP.  The expiry date refers to the last day of that month.   
• Do not store above 30°C.   
• Keep the container/cap tightly closed, in order to protect from moisture.   
• Do not throw away any medicines via wastewater or household waste.  Ask your 
pharmacist how to throw away medicines you no longer use.  These measures will help 
protect the environment.

• The counter starts at either 204 or 064, depending on which size inhaler you have.  The 
number will count down by 1 each time you spray the inhaler.  The counter will stop 
counting at 000. 
• Do not try to change the numbers or take the counter off the metal canister.  The counter 
cannot be reset, and it is permanently attached to the canister. 
• The blue plastic actuator sprays the medicine from the canister.  The actuator has a 
protective cap that covers the mouthpiece.  See Figure A.  Keep the protective cap on the 
mouthpiece when the canister is not in use.  The strap keeps the cap attached to the 
actuator. 
• Do not use the actuator with a canister of medicine from any other inhaler. 
• Do not use a VENTOLIN HFA canister with an actuator from any other inhaler. 
 
Before using your VENTOLIN HFA inhaler 
Before you use VENTOLIN HFA for the first time, you must prime the inhaler so that 
you will get the right amount of medicine when you use it. 
To prime the inhaler, take the cap off the mouthpiece and shake the inhaler well.  Then spray 
the inhaler 1 time into the air away from your face.  See Figure C.  Avoid spraying in eyes.

Spirometry Performance Recommendations 
Spirometry data of the highest quality must be obtained for proper interpretation of the 
results of this protocol.  To these ends, a standard spirometer will be used (provided by 
Pearl), central training provided, qualification will be required, and specific operating 
instruction will also be provided.

Series.  European Respiratory Journal 2005;26(2):319-338. 
FEV1 and FVC Maneuvers 
Equipment Requirements 
The spirometer must be capable of accumulating volume for >15 s (longer times are 
recommended) and measuring volumes of >8 L (body temperature (ie, 37°C), ambient 
pressure, saturated with water vapor, BTPS) with an accuracy of at least +3% of reading or 
+0.050 L, whichever is greater, with flows between 0 and 14 L-s-1.  The total resistance to 
airflow at 14.0 L-s-1 must be <1.5 cmH2O L-1s-1 (0.15 kPa L-1s-1).  The total resistance 
must be measured with any tubing, valves, pre-filter, etc.  included that may be inserted 
between the subject and the spirometer.  Some devices may exhibit changes in resistance due 
to water vapor condensation, and accuracy requirements must be met under BTPS conditions 
for up to 8 successive FVC maneuvers performed in a 10-minute period without inspiration 
from the instrument. 
Display 
For optimal quality control, both flow–volume and volume–time displays are useful, and test 
operators should visually inspect the performance of each maneuver for quality assurance 
before proceeding with another maneuver.  This inspection requires tracings to meet the 
minimum size and resolution requirements set forth in this standard.  Displays of flow versus 
volume provide more detail for the initial portion (first 1 s) of the FVC maneuver.  Since this 
portion of the maneuver, particularly the peak expiratory flow (PEF), is correlated with the 
pleural pressure during the maneuver, the flow–volume display is useful to assess the 
magnitude of effort during the initial portions of the maneuver.  The ability to overlay a 
series of flow–volume curves registered at the point of maximal inhalation may be helpful in 
evaluating repeatability and detecting sub-maximal efforts.  However, if the point of maximal 
inhalation varies between blows, then the interpretation of these results is difficult because 
the flows at identical measured volumes are being achieved at different absolute lung 
volumes.  In contrast, display of the FVC maneuver as a volume–time graph provides more 
detail for the latter part of the maneuver.  A volume–time tracing of sufficient size also 
allows independent measurement and calculation of parameters from the FVC maneuvers.  In 
a display of multiple Studys, the sequencing of the blows should be apparent to the user.  For 
the start of test display, the volume–time display should include >0.25 s, and preferably 1 s, 
before exhalation starts (zero volume).  This time period before there is any change in 
volume is needed to calculate the back extrapolated volume (EV) and to evaluate effort

during the initial portion of the maneuver.  Time zero, as defined by EV, must be presented 
as the zero point on the graphical output.  The last 2 s of the maneuver should be displayed to 
indicate a satisfactory end of test. 
When a volume–time curve is plotted as hardcopy, the volume scale must be >10 mm L-1 
(BTPS).  For a screen display, 5 mm L-1 is satisfactory (Table A1-1).

*The correct aspect ratio for flow versus volume display is two units of flow per one unit of volume 
 
The time scale should be >20 mm-s-1, and larger time scales are preferred (>30 mm-s-1) when 
manual measurements are made.  When the volume–time plot is used in conjunction with a 
flow–volume curve (i.e., both display methods are provided for interpretations and no hand 
measurements are performed), the time scale requirement is reduced to 10 mm-s-1 from the 
usually required minimum of 20 mm-s-1 (Table A1-1).  The rationale for this exception is that 
the flow–volume curve can provide the means for quality assessment during the initial 
portion of the FVC maneuver.  The volume–time curve can be used to evaluate the latter part 
of the FVC maneuver, making the time scale less critical. 
Validation 
It is strongly recommended that spirometry systems should be evaluated using a computer-
driven mechanical syringe or its equivalent, in order to test the range of exhalations that are 
likely to be encountered in the test population.  Testing the performance of equipment is not 
part of the usual laboratory procedures. 
Quality Control 
Attention to equipment quality control and calibration is an important part of Good 
Laboratory Practice.  At a minimum, the requirements are as follows: 1) a log of calibration 
results is maintained; 2) the documentation of repairs or other alterations which return the 
equipment to acceptable operation; 3) the dates of computer software and hardware updates 
or changes; and 4) if equipment is changed or relocated (eg., industrial surveys), calibration 
checks and quality-control procedures must be repeated before further testing begins. 
Key aspects of equipment quality control are summarized in Table A1-2.

Calibration is the procedure for establishing the relationship between sensor-determined 
values of flow or volume and the actual flow or volume.  A calibration check is different 
from calibration and is the procedure used to validate that the device is within calibration 
limits, eg., +3% of true.  If a device fails its calibration check, then a new calibration 
procedure or equipment maintenance is required.  Calibration checks must be undertaken 
daily, or more frequently, if specified by the manufacturer.  The syringe used to check the 
volume calibration of spirometers must have an accuracy of +15 mL or +0.5% of the full 
scale (15 mL for a 3-L syringe), and the manufacturer must provide recommendations 
concerning appropriate intervals between syringe calibration checks.  Users should be aware 
that a syringe with an adjustable or variable stop may be out of calibration if the stop is reset 
or accidentally moved.  Calibration syringes should be periodically (eg, monthly) leak tested 
at more than one volume up to their maximum; this can be done by attempting to empty them 
with the outlet corked.  A dropped or damaged syringe should be considered out of 
calibration until it is checked. 
With regard to time, assessing mechanical recorder time scale accuracy with a stopwatch 
must be performed at least quarterly.  An accuracy of within 2% must be achieved. 
Quality Control for Volume-Measuring Devices 
The volume accuracy of the spirometer must be checked at least daily, with a single 
discharge of a 3-L calibrated syringe.  Daily calibration checking is highly recommended so 
that the onset of a problem can be determined within 1 day, and also to help define day-to-
day laboratory variability.  More frequent checks may be required in special circumstances, 
such as: 1) during industrial surveys or other studies in which a large number of subject 
maneuvers are carried out, the equipment’s calibration should be checked more frequently 
than daily; and 2) when the ambient temperature is changing (eg, field studies), volume 
accuracy must be checked more frequently than daily and the BTPS correction factor 
appropriately updated.

The accuracy of the syringe volume must be considered in determining whether the measured 
volume is within acceptable limits.  For example, if the syringe has an accuracy of 0.5%, a 
reading of +3.5% is appropriate. 
The calibration syringe should be stored and used in such a way as to maintain the same 
temperature and humidity of the testing site.  This is best accomplished by keeping the 
syringe in close proximity to the spirometer, but out of direct sunlight and away from heat 
sources. 
Volume-type spirometer systems must be evaluated for leaks every day.  The importance of 
undertaking this daily test cannot be overstressed.  Leaks can be detected by applying a 
constant positive pressure of >3.0 cmH2O (0.3 kPa) with the spirometer outlet occluded 
(preferably at or including the mouthpiece).  Any observed volume loss of 30 mL after 
1 minute indicates a leak and needs to be corrected. 
At least quarterly, volume spirometers must have their calibration checked over their entire 
volume range using a calibrated syringe or an equivalent volume standard.  The measured 
volume should be within +3.5% of the reading or 65 mL, whichever is greater.  This limit 
includes the 0.5% accuracy limit for a 3-L syringe.  The linearity check procedure provided 
by the manufacturer can be used if it is equivalent to one of the following procedures: 1) 
consecutive injections of 1-L volume increments while comparing observed volume with the 
corresponding cumulative measured volume, eg., 0–1,1–2, 2–3,…6–7 and 7–8 L, for an 8-L 
spirometer; and 2) injection of a 3-L volume starting at a minimal spirometer volume, then 
repeating this with a 1-L increment in the start position, eg., 0–3, 1–4, 2–5, 3–6, 4–7 and 
5-8 L, for an 8-L spirometer.  The linearity check is considered acceptable if the spirometer 
meets the volume accuracy requirements for all volumes tested. 
Quality Control for Flow-Measuring Devices 
With regards to volume accuracy, calibration checks must be undertaken at least daily, using 
a 3-L syringe discharged at least 3 times to give a range of flows varying between 0.5 and 
12 L-s-1 (with 3-L injection times of 6 s and 0.5 s).  The volume at each flow should meet the 
accuracy requirement of +3.5%.  For devices using disposable flow sensors, a new sensor 
from the supply used for patient tests should be tested each day. 
For linearity, a volume calibration check should be performed weekly with a 3-L syringe to 
deliver 3 relatively constant flows at a low flow, then 3 at a mid-range flow and finally 3 at a 
high flow.  The volumes achieved at each of these flows should each meet the accuracy 
requirement of +3.5%. 
VC Maneuvers 
Equipment 
For measurements of VC, the spirometer or flow meter must comply with the requirements 
for FVC (as described previously) and be capable of accumulating volume for >30 s.  
Expiratory maneuvers or, ideally, both inspiratory and expiratory maneuvers should be

included in the display of VC maneuver.  Regardless of whether the inspiratory or expiratory 
maneuver is used for deriving measurements, a display of the entire recorded VC maneuver 
must be provided.  The maximal expiratory volume must be assessed to determine whether 
the subject has obtained a plateau in the expiratory effort.  For display of the slow VC, the 
time scale may be reduced to 5 mm-s-1. 
Technical Considerations 
Minimal recommendations for spirometry systems 
Accurate results require accurate equipment.  Spirometer equipment recommendations apply 
to all spirometers and are minimal requirements.  In some circumstances, it may be 
appropriate to exceed these requirements (ie, in some research/surveillance applications).  
Instrumentation recommendations should be followed to provide accurate spirometric data 
and information that is comparable from laboratory to laboratory and from one time period to 
another.  The accuracy of a spirometry system depends on characteristics of the entire 
system, from the volume or flow transducer and the use of an in-line filter, to the recorder, 
display or processor.  Changes in any aspect of the equipment or errors at any step in the 
process can affect the accuracy of the results.  For example, if the BTPS correction factor is 
wrong, an accurately measured FVC will be incorrectly reported.  Spirometers are not 
required to measure all of the indices in Table A1-3, but must meet the recommendations for 
those that are measured.  Accuracy and repeatability recommendations apply over the entire 
volume range of the instrument.

BTPS correction 
All spirometry values should be reported at BTPS by any method (measuring temperature 
and barometric pressure) proven effective by the manufacturer.  For volume-type 
spirometers, the temperature inside the spirometer should be measured for each breathing 
maneuver.  Regardless of the BTPS correction technique used, the ambient temperature must 
always be recorded with an accuracy of +1°C.  In situations where the ambient air 
temperature is changing rapidly (>3°C in <30 min), continuous temperature corrections may 
be necessary.  Spirometer users should be aware of potential problems with testing performed 
at lower ambient temperatures: 17°C is the lower limit for ambient temperature, unless a 
manufacturer states that their spirometer will operate accurately at lower ambient 
temperatures.  If barometric pressure is not used in calculating the BTPS correction factor, 
the range of barometric pressures over which the BTPS correction factor is valid must be 
published.

Appendix 7 
Spirometry Assessment Criteria 
Acceptable Versus Usable Tests 
Acceptable Tests must meet the following 7 Criteria: 
1. Acceptable start of exhalation with brisk upstroke, no hesitation or false start, and back 
extrapolation volume (EV) <5% of FVC or 0.150 L, whichever is the greater.  (Refer to 
example in Figure A2-1) 
2. No cough during the first second. 
3. No valsalva maneuver. 
4. No leak. 
5. No obstruction of mouthpiece. 
6. No extra breaths. 
7. Plateau achieved, i.e., the volume-time curve shows no change in volume (<0.025 L) for 
≥1 second, and the patient has tried to exhale for at least 6 seconds. 
 
An acceptable test meets all 7 criteria listed.  This is to be considered the “gold standard”. 
Useable spirometry tracings are those that only meet criteria 1 and 2.  When this occurs, 
repeat testing up to 8 attempts in an effort to obtain 3 acceptable spirograms.  If only Usable 
tests are obtained, report results based on the 3 best Usable Studys with observed limitations.

Between-Maneuver Reproducibility Criteria 
After 3 acceptable spirograms have been obtained, apply the following tests 
• The 2 largest values of FVC must be within 0.150 L of each other 
• The 2 largest values of FEV1 must be within 0.150 L of each other 
 
If these criteria are met, the spirometry testing for that time-point may conclude.  The highest 
FEV1 and the highest FVC obtained at each testing time-point (even if from different 
reproducible tracings), will be collected.   
If acceptability criteria are not met, continue testing until they are met or the patient cannot/ 
should not continue (Maximum of 8 attempts).

Rules for Evaluation of Abnormal Liver Laboratory 
Values 
INTRODUCTION  
During the course of the study the Investigator will remain vigilant for increases in liver 
biochemistry.  The Investigator is responsible for determining whether a subject meets 
potential Hy’s Law (PHL) criteria at any point during the study. 
The Investigator participates, together with Pearl clinical representatives, in review and 
assessment of cases meeting PHL criteria to agree whether Hy’s Law (HL) criteria are met.  
Hy’s Law criteria are met if there is no alternative explanation for the elevations in liver 
biochemistry other than Drug-Induced Liver Injury (DILI) caused by study drug.   
The Investigator is responsible for recording data pertaining to PHL/HL cases and for 
reporting AEs and SAEs according to the outcome of the review and assessment in line with 
standard safety reporting processes. 
DEFINITIONS 
• Potential Hy’s Law 
The levels of AST or ALT ≥3x ULN and TBL ≥2x ULN at any point during the study 
irrespective of an increase in ALP.  The elevations do not have to occur at the same time or 
within a specified time frame.  
• Hy’s Law 
The levels of AST or ALT ≥3x ULN and TBL ≥2x ULN, where no other reason, other than 
the study drug, can be found to explain the combination of increases, eg., elevated ALP 
indicating cholestasis, viral hepatitis, or another drug.  The elevations do not have to occur at 
the same time or within a specified time frame. 
IDENTIFICATION OF POTENTIAL HY’S LAW CASES 
In order to identify cases of PHL it is important to perform a comprehensive review of 
laboratory data for any subject who meets any of the following identification criteria in 
isolation or in combination: 
• ALT ≥3x ULN 
• AST ≥3x ULN 
• TBL ≥2x ULN 
 
When a subject meets any of the identification criteria in combination, the central laboratory 
will immediately send an alert to the Investigator and Pearl representative.   
The Investigator will also remain vigilant for any laboratory reports where the identification 
criteria are met, the Investigator will:

• Request a repeat of the test (new blood draw) by the central laboratory. 
 
When the identification criteria are met from central laboratory results the Investigator will 
without delay: 
• Determine whether the subject meets PHL criteria by reviewing all laboratory reports 
including previous visits.  
• Notify the Pearl representative. 
• Promptly enter the laboratory data into the laboratory CRF.  
 
FOLLOW-UP 
Potential Hy’s Law Criteria not met 
If the subject does not meet PHL criteria the Investigator will: 
• Inform the Pearl representative that the subject has not met PHL criteria. 
• Perform follow up on subsequent laboratory results according to the guidance provided in 
the Clinical Study Protocol.  
 
Potential Hy’s Law Criteria met 
If the subject does meet PHL criteria the Investigator will: 
• Notify the Pearl representative who will then inform the central Study Team. 
 
The Medical Monitor contacts the Investigator, to provide guidance, discuss, and agree on 
method of follow up and the continuous review of data.  Subsequent to this contact, the 
Investigator will: 
• Monitor the subject until liver biochemistry parameters and appropriate clinical 
symptoms and signs return to normal or baseline levels, or as long as medically indicated. 
• Investigate the etiology of the event and perform diagnostic investigations as discussed 
with the Pearl Medical Monitor. 
• If at any time (in consultation with the Pearl Medical Monitor) the PHL case meets 
serious criteria, report the event as an SAE using standard reporting procedures. 
 
REVIEW AND ASSESSMENT OF POTENTIAL HY’S LAW CASES 
The instructions in this section should be followed for all cases where PHL criteria are met. 
No later than 2 weeks after the biochemistry abnormality was initially detected, the Pearl 
Medical Monitor contacts the Investigator in order to review available data and agree on 
whether there is an alternative explanation for meeting PHL criteria other than DILI caused

by the study drug.  The Pearl Medical Monitor and other subject matter experts (as 
appropriate) will collaborate in the review and assessment of these cases. 
According to the outcome of the review and assessment, the Investigator will follow the 
instructions below. 
If there is an agreed alternative explanation for the ALT or AST and TBL elevations, a 
determination of whether the alternative explanation is an AE will be made and subsequently 
whether the AE meets the criteria for an SAE: 
• If the alternative explanation is not an AE, record the alternative explanation on the 
appropriate CRF. 
• If the alternative explanation is an AE/SAE, record the AE /SAE in the CRF accordingly 
and follow the standard reporting procedures. 
 
If it is agreed that there is no explanation that would explain the ALT or AST and TBL 
elevations other than the study drug: 
• Report as an SAE (report term “Hy’s Law case”) according to Pearl standard processes.   
• The “Medically Important” serious criterion should be used if no other serious criteria 
apply. 
• As there is no alternative explanation for the HL case, a causality assessment of “related” 
should be assigned. 
 
If, there is an unavoidable delay of over 2 weeks in obtaining the information necessary to 
assess whether or not the case meets the criteria for HL, then it is assumed that there is no 
alternative explanation.  Until an informed decision can be made, the following procedure 
should be followed: 
• Report as an SAE (report term “Potential Hy’s Law”) applying serious criteria and 
causality assessment as per above. 
 
Continue follow up and review according to the agreed plan.  Once the necessary 
supplementary information is obtained, repeat the review and assessment to determine 
whether HL criteria are met.  Update the SAE Report Form according to the outcome of the 
review.

determined at Screening, prior to any study procedures. Approximately 1800 subjects with 
moderate to very severe COPD will be randomized in a 2:2:1:1 scheme into the study to provide

approximately 1600 subjects to complete the study. Approximately 600 subjects each will be 
randomized to the BGF MDI and GFF MDI treatment groups, and 300 subjects each will be 
randomized to the BFF MDI and Symbicort TBH treatment groups. Randomization will be 
stratified by reversibility to Ventolin HFA, country, and disease severity. 
All Japanese sites that participated in Study PT010006 will be eligible to contribute subjects to 
extension study PT010007. It is planned that approximately 324 Japanese subjects with moderate 
to very severe COPD will continue into study PT010007 for an additional 28 weeks to provide 
approximately 300 subjects to complete the study. Based on the randomization ratio from the 
Study PT010006, PT010007 will evaluate approximately 100 completed Japanese subjects in the 
BGF MDI and GFF MDI arms, and approximately 50 completed Japanese subjects in the BFF 
MDI and Symbicort TBH arms. 
In PT010006, subjects who discontinue study treatment prior to Week 24 (Visit 10a) will be 
encouraged to remain in the study to complete all remaining study visits during the 24 week 
treatment period. Subjects who agree to continue to be followed post treatment discontinuation 
will sign an informed consent form (ICF) addendum. All subjects who agree to continue study 
participation beyond treatment discontinuation will complete a Treatment 
Discontinuation/Withdrawal Visit prior to transitioning back to regularly scheduled study visits. 
Subjects participating in a sub-study who choose to discontinue from treatment will only 
complete regularly scheduled visits and not complete any remaining sub-study assessments. 
Treatment discontinuation subjects will return to appropriate maintenance COPD medications, 
per the investigators discretion.  
If a subject chooses not to continue with study assessments, at a minimum the subject will complete 
the Treatment Discontinuation/Withdrawal Visit (refer to the Schedule of Events in the Study 
Protocol). These subjects will return to appropriate maintenance COPD medications, per the 
investigators discretion. A follow-up telephone call will be performed at least 14 days after the last 
study drug dose. In the event the Treatment Discontinuation/Withdrawal Visit is performed >14 days 
post last study drug dosing, a follow-up TC will not be required. These subjects will be followed for 
vital status at 24 weeks post randomization in accordance with the informed consent. 
Sub-Studies: 
The PT010006 study will include the following 3 sub-studies: 
12-Hour PFT Sub-study (US sub-study only): Serial PFTs will be conducted over 12 hours in 
a subset of approximately 600 randomized subjects (200 subjects from each of BGF MDI and 
GFF MDI treatment groups, and 100 subjects from each of the BFF MDI and Symbicort TBH 
treatment groups) at Visit 10a (Week 24). On the test day, additional serial spirometry will be 
obtained at 6, 8, 10, 11.5 and 12 hours post-dose.  
Pharmacokinetic Sub-study: PK assessments will be performed in a subset of subjects who 
participate in the PFT sub-study. Approximately 240 randomized subjects (80 subjects from each

of the BGF MDI and GFF MDI treatment groups, and 40 subjects from each of the BFF MDI 
and Symbicort TBH treatment groups) will be assessed at Visit 10a (Week 24).  
HPA Axis Sub-study: Adrenocorticosteroid activity will be assessed in a subset of subjects in 
the PK sub-study. SC will be measured in approximately 108 randomized subjects (36 subjects 
from each of the BGF MDI and GFF MDI treatment groups, and 18 subjects from each of the 
BFF MDI and Symbicort TBH treatment groups) over 24 hours, between Visits 3 and 4 prior to 
dosing at Randomization and Visit 10a (Week 24).  
The Schedules of Events and Timed Assessments are in the study protocols. 
 
The overall study design is summarized and illustrated in Figure 1.

Prior, Concomitant, Post-Treatment, Prohibited Medications, and Other 
Restrictions (if applicable) 
All prescription and over-the-counter (OTC) medications taken by the subject within 30 days 
before Visit 1 (Screening) will be recorded on the prior/concomitant medications electronic case 
report form (eCRF). All concomitant medications taken during the study will be recorded on the 
Concomitant Medications eCRF page with indication, total daily dose, dose regimen, and dates 
of drug administration. 
3.2
Hypothesis Testing 
For the primary comparisons, the null hypothesis for each pair-wise comparison will be that the 
mean treatment difference is zero (mean treatment effects are equal). The alternative hypothesis 
is that the mean treatment difference is greater than (less than) zero (mean treatment effects are 
not equal). All comparisons will be for superiority except that the comparison of BFF MDI to 
Symbicort TBH will be for non-inferiority and will use margins (įs) of -50 mL for the lower 
bound of a 2-sided 95% CI for the treatment difference for morning pre-dose trough FEV1 and -
75 mL for FEV1 AUC0-4. Margins for secondary endpoints are provided with their descriptions 
below in Section 6.4. P-values will be reported as 2-sided.  
The primary null (H0) and alternative (H1) hypotheses with μ representing the mean are: 
x
H0: μBGF = μGFF 
H1: μBGF  μGFF 
x
H0: μBGF = μBFF 
H1: μBGF  μBFF  
x
H0: μBFF  μSymbicort í 50 mL for morning pre-dose trough FEV1 
H1: μBFF > μSymbicort í 50 mL for morning pre-dose trough FEV1 
Secondary and other efficacy analyses will involve the above hypotheses applied to secondary 
efficacy endpoints. The directionality – being “< “or “>” -- of H1 will depend on the endpoint. 
3.3
Interim Analysis 
No interim efficacy analyses are planned for this study. 
A Data Monitoring Committee (DMC) will review safety data approximately every 6 months. 
Further detail is given in the DMC Charter.  
3.4
Sample Size 
For Study PT010006, it is estimated that a sample size of 1800 subjects (600 per arm in the BGF 
MDI and GFF MDI groups and 300 per arm in the BFF MDI and Symbicort TBH groups) will 
provide the following power estimates, all assuming Type I error control at a 2-sided alpha level

of 0.05 unless specified otherwise: 99% power to detect a difference of 75 mL between BGF 
MDI and BFF MDI in FEV1 AUC0-4 over 24 weeks; 96% power to detect a difference of 35 mL 
between BGF MDI and GFF MDI in morning pre-dose trough FEV1 over 24 weeks and 
approximately 92% power over Weeks 12 to 24; 97% power to detect a difference of 50 mL 
between BGF MDI and BFF MDI in morning pre-dose trough FEV1 over Weeks 12 to 24; and 
96% power to demonstrate non-inferiority of BFF MDI to Symbicort TBH in morning pre-dose 
trough FEV1 over 24 weeks and approximately 92% power over Weeks 12 to 24 based on a 
margin of 50 mL (one-sided, alpha=0.025) assuming no true difference.  
Assumptions regarding variability for the primary endpoint are based on Pearl’s experience with 
Phase IIb and III clinical studies. A composite value standard deviation (SD) of 200 mL for the 
change from baseline at each visit has been assumed for trough FEV1 and 220 mL for FEV1 
AUC0-4. Dropout is anticipated to be approximately 12% by the end of the study. Based on the 
repeated measures (RM) analysis, an effective SD for the change over 24 weeks of 157 mL and 
173 mL for trough FEV1 and FEV1 AUC0-4, respectively, is assumed. For Weeks 12 to 24, an 
effective SD for trough FEV1 of 171 mL is assumed. 
For Study PT010007, the sample size of 324 (108 per arm in the BGF MDI and GFF MDI 
groups and 54 per arm in the BFF MDI and Symbicort TBH groups) includes all Japanese 
subjects who were enrolled in Study PT010006. The sample size was not calculated to achieve 
statistical power but was selected to provide approximately 100 completing subjects in the BGF 
MDI and GFF MDI arms.

DATA AND ANALYTICAL QUALITY ASSURANCE 
The overall quality assurance procedures for the study data, statistical programming and analyses 
are described in Standard Operating Procedures (SOPs) of Everest Clinical Research. Detailed 
data management procedures are documented in the study Data Management Plan, Data 
Validation Check Specifications, and Integrated Safety Data Review Plan. Detailed statistical 
and programming quality control and quality assurance procedures are documented in the 
Statistical Analysis and Programming QC/QA Plan. 
Transfer of PFT data from the central PFT laboratory (iCardiac PFT Global) to Everest Clinical 
Research will be defined in the iCardiac DMP (Data Management Plan), and data handling rules 
related to this data are included in Appendix 1 of this SAP. The quality of all PFTs obtained at 
each time point will be graded independently at iCardiac by qualified personnel. Quality grading 
assessments will be based on ATS (American Thoracic Society)/ERS criteria and will be 
included in data transfers.

ANALYSIS POPULATIONS 
5.1
Population Definitions 
5.1.1
Intent-to-Treat (ITT) Population (PT010006 only) 
The ITT Population is defined as all subjects who are randomized to treatment and receive any 
amount of the study treatment in Study PT010006. Subjects will be analyzed according to 
randomized treatment group. Data obtained after discontinuation of treatment, but prior to 
withdrawal from the study, will be included. The ITT population will be used for sensitivity 
analyses. 
5.1.2
Modified Intent-to-Treat (mITT) Population (PT010006 only) 
The mITT Population is a subset of the ITT Population, defined as all subjects with post-
randomization data obtained prior to discontinuation from treatment in Study PT010006. Any 
data collected after completion of or discontinuation from randomized study medication will be 
excluded. Subjects will be analyzed according to randomized treatment group. (Note that a 
subject who used a study treatment, but took less than one full dose of treatment will qualify for 
this population). The mITT Population will be the primary population for all efficacy analyses 
except for the non-inferiority analyses. Note: The knowledge that a subject did not have a COPD 
exacerbation constitutes an efficacy assessment. 
5.1.3
Japanese Modified Intent-to-Treat (mITT) Population 
The Japanese mITT Population is defined as the subgroup of the mITT Population who are 
Japanese subjects (enrolled at sites in Japan) from Study PT010006, regardless of participation in 
Study PT010007. Subjects will be analyzed according to the active treatment they were assigned 
to at randomization in Study PT010006. Data from both Study PT010006 and Study PT010007 
will be included. 
5.1.4
Rescue Ventolin User Population (RVU) (PT010006 Only) 
Regional differences in rescue Ventolin HFA usage are expected with subjects in some countries 
using virtually no rescue medication at study entry. Therefore, the RVU Population is defined as 
all subjects in the ITT Population with mean baseline Rescue Ventolin use of  1.0 puff/day. 
5.1.5
Per-Protocol (PP) Population (PT010006 only) 
The PP Population is a subset of the ITT Population, defined as all subjects with post-
randomization data obtained prior to any major protocol deviations in Study PT010006. Data 
obtained after any major protocol deviation or discontinuation from treatment will be excluded. 
Since receiving the wrong treatment is a major protocol deviation, data after the deviation from 
such subjects will be excluded from the PP Population. If the first treatment received is the 
wrong treatment then the subject will be excluded entirely from the PP population. Any 
evaluability criteria with a potential impact on efficacy results will be identified during Blinded 
Data Review Meeting (BDRM) prior to database lock. Major protocol deviations, therefore, can 
result in exclusion of all data from a particular subject from the PP Population or require 


BGF MDI/GFF MDI/BFF MDI 
Protocols PT010006 and PT010007 
Version 2.0

Page 28 of 355
 
 
exclusion of data from a specific time point and/or subsequent time points for an endpoint. The 
PP Population will be the main population for all non-inferiority analyses.  
Protocol deviations and criteria for exclusion from the PP Population will be established at a 
BDRM prior to database lock. Reasons for exclusion from the PP Population will include, but 
are not limited to, the following: 
1. An incorrect diagnosis of COPD. 
2. Subjects who do not have an established clinical history of COPD and severity where 
an established clinical history of COPD and severity is to be identified at the BDRM. 
3. For those subjects who use rescue Ventolin HFA less than 6 hours before study visit, 
all data post-Ventolin HFA administration will be considered missing for that day. 
4. For subjects who take any protocol-prohibited medication that would affect 
spirometry assessments on the date of an assessment, spirometry measurements taken 
at that assessment will be excluded.  
5. For spirometry endpoints, the subject will not be eligible for the endpoint-specific, 
visit-specific PP Population if the subject did not take study medication in the 
evening prior to the visit day. 
6. Subjects are also excluded from the PP Population for PFT endpoints if the following 
condition is true: 
-
Subjects who cannot meet protocol-specified baseline stability criteria. FEV1 baseline 
stability is defined as the mean of the -60 minute and -30 minute pre-dose FEV1 
assessments at Visit 4 being within ±20% or 200 mL of the mean of the pre-
bronchodilator FEV1 assessments obtained at the 2 preceding visits (average of pre-
dose FEV1 assessments obtained at Visit 2 and Visit 3). 
Subjects who fail to meet any of the three restriction criteria prior to spirometry will be 
handled as follows. The 3 restrictions are (1) subject was not to smoke for at least 4 
hours prior to study visit and throughout the duration of each study visit, (2) subject 
was not to use xanthine-containing products (i.e., coffee, tea, cola and chocolate) for 
at least 6 hours prior to study visit and for the duration of each study visit, and (3) 
subject was not to have COPD bronchodilator medications for at least 6 hours prior to 
study visit. Spirometry data for these subjects at the affected visits will be removed 
from the PP Population for PFT endpoints. Such restrictions will be applied only if 
data pertaining to the meeting of the criteria (including the timing) were collected. 
 
5.1.6
Safety Population (PT010006 only) 
The Safety Population is defined as all subjects who are randomized to treatment and receive at 
least one dose of the study treatment in Study PT010006. However, subjects will be analyzed 
according to treatment received rather than randomized. If a subject received more than one 
randomized treatment, they will be analyzed and included in summaries according to the 
treatment they received the most. Subjects receiving no study treatment will be excluded, as will

Protocols PT010006 and PT010007 
Version 2.0

subjects who have no post-dose safety assessments. Note: The statement that a subject had no 
AEs also constitutes a safety assessment. 
5.1.7
Japanese Safety Population 
The Japanese Safety Population is a subset of the Safety Population that is defined as all 
Japanese subjects (enrolled at sites in Japan) who received any amount of study medication in 
Study PT010006, regardless of participation in Study PT010007. Subjects will be analyzed 
according to the actual treatment they received. Data from both Study PT010006 and Study 
PT010007 will be included. 
5.1.8
PT010007 Safety Population 
The PT010007 Safety Population is defined as all subjects who received any amount of study 
medication in Study PT010007. Subjects will be analyzed according to the actual treatment they 
received. Data from both Study PT010006 and Study PT010007 will be included. 
5.1.9
PK Population 
The PK Population is defined as all randomized and treated subjects who have sufficient data to 
reliably calculate at least one PK parameter in Study PT010006. Subjects will be analyzed 
according to treatment received rather than randomized. 
The PK Population will be determined after review of the clinical study data (e.g., concomitant 
medications, dosing information from the subject diary, and adverse events). Prior to the final 
PK analysis, subject data as well as protocol deviations will be reviewed in a blinded manner by 
Everest and Pearl at the BDRM for inclusion/exclusion into the PK Population. 
5.1.10
HPA Axis Population 
The HPA Axis Population is defined as all subjects who participated in the HPA axis sub-study. 
The HPA Axis Population is a subset of the Safety Population without protocol deviations which 
could affect SC endpoint and whose serum samples did not have confounding factors that would 
affect the interpretation of the results. Exclusion from the HPA Axis Population will be 
established at a blinded data review meeting prior to database lock. Subjects will be analyzed 
according to treatment received rather than randomized. 
5.2
Populations for Primary and Sensitivity Analyses 
PT010006: 
Demographics will be summarized for the mITT, PP, Safety, and Non-randomized Populations 
as well as for subjects participating in the 12-hr PFT, PK, and HPA Axis sub-studies.  
Extent of exposure will be summarized for the Safety Population. The Safety Population will be 
used to summarize safety.

Efficacy Analyses will be performed for the ITT, mITT, and PP Populations. The mITT 
Population will be used for the primary efficacy analyses, with the ITT and PP populations being 
considered supportive with one exception. The PP Population will be primary for the non-
inferiority comparisons of BFF MDI vs. Symbicort TBH.  
PK will be summarized for the PK Population. HPA Axis results will be summarized for the 
HPA Axis Population.  
Selected analyses will be performed for specified sub-populations. See the Subgroup Analyses 
section (Section 6.4.9). 
PT010007:  
When the final database for PT010007 becomes available, selected safety and efficacy results 
will be generated using the Japanese Safety and Japanese mITT populations respectively. 
Selected AE summaries will be repeated on the PT010007 Safety Population. 
 
6.
STATISTICAL ANALYSIS 
Study PT010006 analyses will be performed when the PT010006 final database is available, with 
PT010007 analyses to be performed later once the PT010007 final database is available. 
All data collected contributing to the analysis will be provided in listings. Data for all subjects 
who are randomized will be included in the subject data listings. Data for non-randomized 
subjects will be listed where available. 
All safety and efficacy parameters will be summarized by treatment unless specified otherwise. 
Continuous variables will be summarized with descriptive statistics (the number of non-missing 
values, mean, standard deviation, median, minimum, and maximum). Additionally, the 25th and 
75th percentiles will be presented when appropriate based on historical knowledge of the 
normality or non-normality of the distribution of underlying data. 
Categorical variables will be summarized with frequency counts and percentages (where 
appropriate). 
6.1
Data Handling Rules and Definitions, Including Handling of Missing Data 
Missing data will be maintained as missing in the analysis datasets, unless specified otherwise. 
For variables where missing data are imputed, the analysis dataset will contain a new variable 
with the imputed value and the original variable value will be maintained as missing. 


BGF MDI/GFF MDI/BFF MDI 
Protocols PT010006 and PT010007 
Version 2.0

Page 31 of 355
 
 
Data Imputation for Adverse Events Summaries by Severity and Relationship to Study Drug 
For the AE summaries by severity (mild, moderate, or severe), an AE with missing severity will 
be deemed as severe. For the AE summaries by relationship to study drug, an AE with a missing 
relationship to study drug will be deemed as definitely related. Imputed values will not be listed 
in data listings. 
Data Imputation for Laboratory, Vital Sign, and ECG Summaries (Continuous Parameters) 
Data from unscheduled visits will not be used for by-visit summaries. Data from both scheduled 
and unscheduled visits will be used for the end-of-treatment summary, for shift tables and for 
determining incidence of clinically significant values. 
Data Imputation (All Laboratory Summaries) 
Laboratory values of ‘>=x’ or ‘<=x’ will be taken as the value of x in the analyses. If a 
laboratory value is prefixed with‘>’: the available original value +0.001 will be used for table 
summaries; if a laboratory value is prefixed with ‘<’, then the original value –0.001 will be used 
in table summaries. 
Study Dates and Day of Assessment or Event 
Study Day and Day of Assessment or Event definitions are provided in Appendix 1, Data 
Handling Rules. 
On-treatment COPD exacerbations 
An exacerbation will be considered “on-treatment” if its start date is before or on the last 
treatment date. For treatment discontinuations, this definition is extended to include 
exacerbations starting one day after the last treatment date. (If it is decided during a clinic visit to 
discontinue study drug and to switch to a treatment for the ongoing exacerbation symptoms, the 
subject typically would not take the morning dose of study drug at that visit, and their 
exacerbation start date will be one day after the last treatment date. Such exacerbations will still 
be considered “on-treatment”). 
6.2
Subject Disposition and Analysis Populations 
A disposition table for PT010006 for all subjects randomized will be provided (Table 1.1.1.1). 
This tabulation will include the number of subjects in each randomized treatment who were not 
treated, who received the study treatment, who discontinued treatment prematurely, who 
discontinued treatment prematurely but completed the study, who discontinued treatment 
prematurely and withdrew from the study, who withdrew from the study prematurely, and who 
completed the study. The number and percentage of randomized subjects included in the mITT, 
Japanese mITT, ITT, PP, Safety, Japanese Safety, 12-hr PFT Sub-study, PK, and HPA Axis 
Populations will also be tabulated (Table 1.1.1.1). A disposition table for subjects in PT010006 
and PT010007 will also be provided (Table 1.1.1.2). Informed consent is listed in Listing 9.7.

The numbers of subjects randomized and in the analysis populations will be provided by country, 
center, and treatment in Table 1.1.2. The number of subjects randomized by stratification factor 
and cross-classification of reversibility to Ventolin HFA and disease severity, using interactive 
web response system (IWRS) data and Clinical data for the stratification-factor levels, will be 
tabulated in Tables 1.1.5.1, 1.1.5.2, 1.1.6.1, and 1.1.6.2, respectively. If there are any subjects 
who took study treatment other than what was randomized during the study, both the treatment 
assigned at randomization and actual treatment(s) received during the Treatment Period will be 
listed (Listing 1.3). The duration of actual treatment will also be listed (Listing 1.3). A list of the 
discrepancies between IWRS-based and clinical-data-based stratification factors will be provided 
(Listing 1.6). 
A summary of reasons subjects were not randomized will be provided for all subjects not 
randomized (Table 1.1.3). A listing of reasons subjects were not randomized will also be 
provided (Listing 1.4). Subjects excluded from the ITT, mITT, PP, Safety, PK and HPA Axis 
analysis populations will be summarized (Table 1.1.4) for all subjects randomized. Reasons for 
premature discontinuation from study treatment will be summarized for the Safety Population 
and for the Japanese Safety Population (Table 1.2.1 and Table 1.2.2 respectively).
The number and percentage of subjects in the ITT Population who withdrew from the study will 
be tabulated by reason for withdrawal (Table 1.2.3).
The reason for exclusion from the PP Population will be tabulated by study treatment for all 
mITT subjects (Table 1.3.1). The reason for exclusion of a subject from the ITT, mITT, PP, 
Safety, PK and HPA Axis Populations or exclusion of partial data (at some but not all time 
points) for a subject will be listed for all randomized subjects (Table 1.1.4). A listing of subjects 
who did not comply with restrictions on smoking, use of rescue medication, and xanthine-
containing products (protocol deviations requiring removal of data from the PP Population 
analysis) just prior to spirometry will be provided in Listing 6.1.1. Use of rescue medication at 
pre-dose or during the post-dose assessments on each specific test day (yes/no), will be tabulated 
in Listing 6.1.3. In addition, the eligibility information (inclusion/exclusion criteria with any 
waivers granted) of all subjects who are randomized will be listed (Listing 2.1). 
The number and percentage of subjects with changes in smoking status after the start of study 
treatment will be tabulated by randomized treatment, by visit and overall during the study, in 
Table 1.13 (Safety Population) and Table 1.14 (Japanese Safety Population) (Listing 1.5).
6.3
Demographic and Baseline Characteristics and Extent of Exposure 
The definitions for the derived demographic or baseline characteristic variables can be found in 
Appendix 1. 
6.3.1
Demography, Physical Characteristics, CAT 
Subject demographics, total CAT score, use of inhaled corticosteroids (ICS) at screening, and 
smoking status/history will be summarized for the mITT, PP, and Safety Populations and for 
Non-Randomized subjects (Tables 1.4.1.1 through 1.4.5.1, respectively, and Listing 1.2). The

ITT population does not need to be tabulated because it is the same as the mITT population for 
demographics. If the Safety Population has the same treatment assignment as the mITT, then it 
will be identical as well and hence not produced. Use of ICS (yes/no) will be summarized for all 
populations except for the Non-Randomized subjects. Demographics will also be summarized for 
the subjects in the 12-hr PFT sub-study (Tables 1.4.6.1 through 1.4.6.4), HPA Axis Population 
(Tables 1.4.6.5 through 1.4.6.8), and PK Population (Tables 1.4.6.9 through 1.4.6.12). 
Demographics and baseline characteristics will also be summarized for subjects in the Japanese 
mITT, Japanese Safety, and PT010007 Safety Populations (Tables 1.4.7.1, 1.4.7.2, 1.4.7.3). 
Demographic and baseline characteristic variables summarized will include the following:

COPD History, Screening/Baseline Spirometry, and Reversibility 
Duration of COPD and the number of years prior to the start of study medication that COPD was 
first diagnosed (calculated as [Date of First Dose of Study treatment in the study – Date COPD 
First Diagnosed] /365.25) will be summarized by treatment and for all subjects for the mITT, 
Safety, Japanese mITT, and Japanese Safety Populations and listed (Tables 1.5.1, 1.5.4, 1.5.5, 
and 1.5.8 and Listing 4.1). Severity of COPD at Screening Visit 2 post-Ventolin HFA will also 
be included in these summaries. History of moderate or severe COPD exacerbations within the 
past 12 months will be summarized and listed for subjects in the Safety, Japanese Safety, 
PT010007, mITT and Japanese mITT Populations (Table 1.9.4, Table 1.9.5, Table 1.9.6, Table

1.9.7 and Listing 4.3). Severity of COPD is defined in terms of baseline FEV1, as found in the 
Data Handling Rules (Appendix 1). 
Descriptive statistics will be provided for screening period pre-bronchodilator and 
post-bronchodilator and baseline spirometry parameters (Tables 1.6.1, 1.6.2, 1.6.3, 1.6.4, and 
1.6.5, for the mITT, ITT, PP, Japanese mITT Populations, and 12-hr PFT Sub-study, 
respectively, and Listings 2.2 and 2.3). 
Characterization of Reversibility: 
Reversibility to Ventolin HFA (short-acting ȕ2-agonist, SABA) will be evaluated at Visit 2. 
Reversibility to Atrovent HFA (short-acting anticholinergic) will be evaluated at Visit 3. 
Reversibility to Ventolin HFA (obtained at Visit 2) will be used as a stratification variable at 
randomization to ensure an even distribution of reversibility across the treatment arms. 
Reversibility to Atrovent HFA will be used to characterize the population.  
Reversibility (%) to a bronchodilator is defined as 100 x (the change from pre-bronchodilator 
HFA to post-bronchodilator HFA for FEV1)/pre-bronchodilator HFA FEV1. Reversible (Yes/No) 
is defined as improvement in FEV1 post-bronchodilator HFA administration compared to pre-
bronchodilator HFA of >=12% and >=200mL. 
Reversibility to Ventolin HFA at Screening Visit 2 and reversibility to Atrovent HFA at 
Screening Visit 3 will be summarized for the mITT, 12-hr PFT Sub-study, and Japanese mITT 
Populations and listed (Tables 1.7.1 to 1.7.5, and Tables 1.8.1 to 1.8.5 for Ventolin HFA and 
Atrovent HFA reversibility, respectively, and Listings 2.2 and 2.3 for Ventolin HFA reversibility 
and Atrovent HFA reversibility respectively, and Listing 5.2 for Atrovent HFA and Ventolin 
HFA dispensing). The number and percentage of subjects reversible will be included in these 
summaries. A summary of the change in FEV1 from pre-dose FEV1 to post-bronchodilator 
assessment will also be included. If multiple time points are available post-bronchodilator, then 
the one with the highest FEV1 will be used. 
Additionally, the number and percentage of subjects meeting each of the following response 
criteria will be summarized for both Ventolin HFA and Atrovent bronchodilators: 
x
12% improvement post-bronchodilator in FEV1 from pre-bronchodilator 
x
150 mL improvement post-bronchodilator in FEV1 from pre-bronchodilator 
x
200 mL improvement post-bronchodilator in FEV1 from pre-bronchodilator

Testing
Medical and Surgical History at Screening will be summarized for the Safety Population and 
Japanese Safety Population and listed for all randomized subjects (Table 1.9.1.1, Table 1.9.1.2, 
and Listing 4.4). Cardiovascular medical history of interest at Screening will be summarized for

the Safety Population and Japanese Safety Population and listed for all randomized subjects 
(Table 1.9.2.1 and Table 1.9.2.2 and Listing 4.5). 
Screening Reproductive Status and Pregnancy Testing Results will be listed (Listing 4.6). 
Subjects’ history of moderate or severe COPD exacerbations within the past 12 months will be 
summarized for the Safety, Japanese Safety, PT010007 Safety, mITT, and Japanese mITT 
Populations (Tables 1.9.3 through 1.9.7). 
6.3.4
Prior, Concomitant, and Post-Treatment Medications/Treatments 
All prescription and OTC medications taken by the subject during 30 days before Screening will 
be recorded on the Concomitant Medications case report form (CRF) page. 
Coding: Verbatim medication/treatment terms will be coded by Everest Clinical Research and 
will be assigned a preferred term (PT) and an ATC (anatomic therapeutic class) term using the 
latest version of the World Health Organization Drug Dictionary (WHO-DD) available (version: 
3Q2016 or later). 
Multiple ATC assignments: If there are multiple ATC codes assigned to the same concomitant 
medication, the “primary” one based on a Pearl medical evaluation will be used. All prior 
medication taken by the subject within 30 days of Screening for the study and all concomitant 
therapy taken by the subject while on study will be recorded in the eCRF. 
Prior medication/treatment is any medication/treatment taken prior to study treatment, even if 
this medication continued to be taken on the day of the start of study treatment in the study or 
afterward (Appendix 1).
Concomitant medication/treatment is any medication/treatment reported as being taken after 
the start of the randomized study treatment in the study and being taken on or before the date 
prior to the last dose of study treatment for the subject. A medication with an onset date on or 
after the date of discontinuation from or completion of randomized study treatment for the 
subject will not be considered concomitant, but will be considered a Post-Treatment
medication/treatment. 
Any medication/treatment which cannot be identified as Prior, Concomitant, or Post-Treatment 
will be considered as being in each of the categories that are possible from the available 
information. 
Concomitant COPD-related, COPD exacerbation-related, and Non-COPD related 
medications/treatments will be summarized by preferred term and actual treatment received for 
the Safety Population (Tables 1.11.1, 1.11.1b, 1.11.2, 1.11.5.1 to 1.11.8) and Japanese Safety 
Population (Tables 1.11.3, 1.11.4). COPD-related summaries will not include the COPD-
exacerbation medications. Prior, concomitant/post-treatment COPD, COPD exacerbation, and 
Non-COPD medications will be displayed in separate listings (Listings 4.7 and 4.8, respectively).

Reported prior medications for COPD and non-COPD-related medications will be tabulated for 
the Safety Population (Tables 1.10.1.1 and 1.10.2) and the Japanese Safety Population (Tables
1.10.3 and 1.10.4) and listed separately (Listings 4.7 and 4.8, respectively). 
Prior COPD Medications will be tabulated (for the Safety population) for subjects having 
received any one, two, all three, or none of the following treatments whether in fixed 
combination products or separate are used at the time of screening and separately for post-
treatment (for any duration): (1) a muscarinic antagonist, (2) a ȕ2 agonist, and (3) an ICS (Table
1.10.1.2). For this purpose, scheduled SAMA (Short-acting muscarinic antagonist) or SABA 
treatments are included. In addition, tabulations for long-acting muscarinic antagonists (LAMA) 
and long-acting ȕ2 agonists (LABA) will also be included. 
Post-treatment medications will be tabulated for subjects having received any one, two, all three, 
or none of the following treatments: (1) a muscarinic antagonist, (2) a ȕ2 agonist, and (3) an ICS 
(Table 1.11.5.2). 
6.3.5
Extent of Exposure to Study Medication and Compliance 
Subject’s exposure to a study treatment will be determined by the duration of time (days) for 
which the doses were administered, defined as “([End date of treatment – Date of first dose of 
treatment] + 1)”. Percent compliance is defined as (total number of puffs of study treatment 
taken on a study day/total expected puffs taken on a study day) averaged across all days of a 
subject’s dosing between start of study treatment and last day on study treatment x 100. The 
expected number of puffs for a test day which is the last date of treatment will be 2, and the 
expected number of puffs for the last date of treatment which is not a test day will be 4 when a 
PM dose is taken but will be 2 otherwise; the expected number of puffs on dates prior to the last 
date of treatment will be 4. 
 
The number of days of exposure to study treatment will be summarized for each treatment for the 
Safety Population and Japanese Safety Population. The total person-years of exposure for a 
treatment group, defined as the total exposure in the study across all subjects in the treatment, 
will also be provided by treatment (Table 1.12.1 for the Safety Population, Table 1.12.2 for the 
Japanese Safety Population, Table 1.12.3 for PT010007 Safety Population). In addition, 
treatment compliance will be provided in this summary. The treatment compliance will be 
categorized into 7 different groups depending on the degree of compliance: 0 – <20%, 20 – 
<40%, 40 – <60%, 60 – <80%, 80 – 100%, >100 – 120%, and >120%. Descriptive 
statistics (n, mean, standard deviation, median, minimum and maximum) for percent compliance 
will also be provided by treatment. Treatment compliance will be reported in Listing 5.3. A 
listing of treatment dosing and dispensing information will be provided in Listing 5.1. Any 
comments related to study medication or any other additional study comments will be listed 
(Listing 9.6).

Efficacy Analyses 
For study PT010006, there are four pairwise comparisons of treatments of interest, namely,

However, summary statistics will be provided by randomized treatment and for each treatment 
difference for all comparisons. All comparisons will be performed for testing superiority except 
that the comparison of BFF MDI to Symbicort TBH will be for non-inferiority. Superiority 
comparisons will chiefly use the mITT population. Non-inferiority analyses will chiefly use the 
PP population, unless specifically stated otherwise. In order for non-inferiority to be met, the 
confidence bound (on the side of lower efficacy for BFF) from a 95% two-sided confidence 
interval (for the treatment difference or treatment ratio [as applicable]) must be less extreme than 
the non-inferiority margin. 
6.4.1
Estimands 
 
The primary estimand of interest is called the efficacy estimand and is the effect of the 
randomized treatments in all subjects assuming continuation of randomized treatments for the 
duration of the study regardless of actual compliance. There are three additional estimands of 
interest. One is called the attributable estimand and is the effect of treatment in subjects 
attributable to the randomized treatment. For this estimand, discontinuation of randomized 
medication for reasons such as tolerability or lack of efficacy are considered unfavorable 
outcomes. Another estimand of interest is called the treatment policy estimand. This estimand is 
the effect of randomized treatment over the study period regardless of whether randomized 
treatment is continued. The final estimand of interest is called the per protocol estimand. This 
estimand is the effect of treatment on subjects who are compliant with the protocol (i.e. no major 
protocol deviations), including the use of randomized medication. 
The primary analysis for the efficacy estimand will be conducted using the mITT Population 
where only data obtained prior to subjects discontinuing from randomized treatment will be 
utilized. This assumes that efficacy observed on treatment is reflective of what would have 
occurred after discontinuation of randomized treatment had they remained on treatment.  
The second estimand of interest is the attributable estimand. Analyses of the attributable 
estimand will be conducted in the mITT Population. Data that are missing due to treatment 
discontinuation will be imputed based on the 5th percentile of the reference arms’ distribution if 
the reason is reasonably attributable to tolerability or lack of efficacy. The 5th percentile applies 
to an endpoint for which a higher value is a better outcome; however the 95th percentile applies 
to an endpoint for which a lower value is a better outcome. Other missing data are to be imputed 
using the observed data model, i.e. assumed to be missing at random (MAR). The number of 
imputations used for the derivation of the attributable estimand will be between 100 and 1000.

More detail about the computation of the attributable estimand will be provided in subsequent 
sections (especially 6.4.4.1) and in the Details Appendix to this SAP. 
Treatment discontinuations reasonably attributable to tolerability or lack of efficacy will be 
identified during the BDRM and documented in the minutes prior to unblinding. 
Discontinuations will be attributed to tolerability if the subject had an adverse event determined 
by the investigator to be possibly, probably, or definitely related to study drug, and for which 
study drug was permanently discontinued. Discontinuations will be attributed to lack of efficacy 
if ‘lack of efficacy’ is indicated to be the primary reason for discontinuation from study drug. For 
the remaining discontinuation categories, where specific reasons or criteria frequently need to be 
considered, decisions will be made and documented at the BDRM. Once these subjects are 
identified, post-treatment discontinuation FEV1 values for each patient will be imputed based on 
the 5th percentile of the reference arms’ distribution.  
The third estimand of interest is the treatment policy estimand. Analyses of the treatment policy 
estimand will be conducted in the ITT Population, in which all observed data will be utilized 
regardless of whether subjects remain on randomized treatment.  
Finally, the last estimand of interest is the per protocol estimand. Analysis of this estimand will 
use the PP Population. 
6.4.2
Baselines and Baseline Covariates for Analysis 
The mean of all evaluable 60- and 30-minute pre-dose spirometry assessments conducted at 
Day 1 (Visit 4) will be used to establish baseline for all FEV1, FVC, FEF25-75, and PEFR 
parameters. 
For the diary symptom score parameters and rescue medication usage, baseline will be the mean 
of the non-missing values from the diary data collected in the last seven days of the Screening 
Period. 
For the SGRQ scores, baseline will be the value of the score calculated using the Day 1 
questionnaire data collected prior to the start of randomized study treatment. 
Baseline COPD exacerbation history is set to 0, 1, or  2 moderate or severe exacerbations in the 
last 12 months (from the Visit 1 CRF page).  
Baseline percent predicted FEV1 is the mean of the 30 minute and 60 minute values of FEV1 
prior to dosing on Day 1 (Visit 4). 
ICS use at screening (Yes or No) is to be defined as follows. A subject was considered to have 
had “ICS Use at Screening” if: 
x
the subject was taking a medication that contained a component (active ingredient) that is 
in the WHODRUG SDG (standardized drug grouping) of “CORTICOSTEROIDS”, and

x
the route of administration was “INHALED”, and the medication was used at any time 
during the screening period (or in the 30 days prior to the screening period). Medications 
may be but are not necessarily ongoing medications. 
 
Baseline blood eosinophil count is the mean of non-missing blood eosinophil count values prior 
to the first dose of study medication. 
Baseline age is the age in years at the time of Informed Consent. 
Baseline post-bronchodilator FEV1 is the highest value of FEV1 obtained approximately 30 
minutes after dosing with Ventolin (or later if there are repeated assessments) at Visit 2 unless it 
is missing, in which case the post-Atrovent value at Visit 3 will be used.  
The baseline post-bronchodilator percent predicted FEV1 is the baseline post-bronchodilator 
FEV1 divided by the predicted FEV1 and multiplied by 100. 
Baseline percent reversibility to Ventolin is 100 x (POST-PRE)/PRE, where POST is the highest 
value of FEV1 obtained 30 minutes (or later if there are repeated assessments) after dosing with 
Ventolin at Visit 2 and PRE is the mean of the 30 minute and 60 minute values of FEV1 prior to 
dosing with Ventolin at Visit 2. 
6.4.3
Visits and Time Windows for Visit-Based Efficacy Assessments 
Efficacy data obtained during unscheduled visits will not be used for any of the pre-defined 
efficacy analyses. Efficacy from scheduled and unscheduled visits will be listed.  
For efficacy analysis or derivation of AUC based on time points, the change from baseline in 
PFT assessments will be allocated to derived nominal collection time windows using the time 
intervals specified for each below.

Change from Baseline in Morning Pre-Dose Trough FEV1
PT010006: 
Change from baseline in morning pre-dose trough FEV1 at each visit is defined as the mean of 
the 60 and 30 minute pre-dose values minus baseline. In subjects missing either of these pre-dose 
assessments, the value will be calculated from the single measurement. In subjects missing both 
pre-dose values, morning pre-dose trough FEV1 at that visit will not be calculated.

The change from baseline in morning pre-dose trough FEV1 will be analyzed using an RM linear 
mixed model. The model will include treatment, visit, treatment by visit interaction, and ICS use 
at Screening as categorical covariates and baseline FEV1, baseline eosinophil count, and percent 
reversibility to Ventolin HFA as continuous covariates. Baseline FEV1 is defined as the mean of 
the non-missing -60 minute and -30 minute values obtained prior to dosing at Visit 4, and 
baseline eosinophil count is defined as the mean of non-missing eosinophil counts prior to the 
first dose of study treatment. An unstructured correlation (UN) matrix will be used to model 
correlation within a subject. If the UN model fails to converge, then a first-order autoregressive 
(AR(1)) structure will be used instead. In the AR(1) model, subject will be included as a random 
effect. 
Contrasts will be used to obtain estimates of the treatment differences over Weeks 12 to 24 
(primary for Japan/China), over 24 weeks (i.e. Weeks 4 to 24) (primary for EU and Canada; 
secondary for Japan/China; secondary for US), at Week 24 (primary for US), and at each post-
randomization visit (“other” endpoint). Subject data from the first 24 weeks post-randomization 
will be included in the analyses. Two-sided p-values and point estimates with two-sided 95% 
confidence intervals (CIs) will be produced for each treatment difference.  
All comparisons will be for superiority except that the comparison of BFF MDI to Symbicort 
TBH will be for non-inferiority and will use a margin of -50 mL for the lower bound of a 2-sided 
95% CI for the treatment difference. The primary analysis will be conducted using the efficacy 
estimand except for the non-inferiority comparisons of BFF MDI vs. Symbicort TBH, for which 
the per protocol estimand will be primary treatment (Tables and Figures 2.1.1, 2.1.3, 2.1.5, and
Figures 2.1.6.1, to 2.1.6.10 for the efficacy estimand, the attributable estimand, the treatment 
policy estimand, and the per protocol estimand, respectively). Efficacy data from unscheduled 
visits will not be used for this analysis. Additional figures will display the change from baseline 
in morning pre-dose trough FEV1 by completion vs. discontinuation patterns for the efficacy 
estimand, the attributable estimand, and the treatment policy estimand (Figures 2.1.6.11 to 
2.1.6.14). 
The attributable estimand will use the mITT Population but then impute missing post-treatment 
discontinuation data based on the 5th percentile of the reference arms’ (BFF’s and GFF’s 
combined) distribution if the reason for discontinuation is attributable to lack of efficacy 
or/tolerability. All other missing data will be imputed using the observed data model. The 
variance used for the multiple imputation is described in the Details Appendix to this SAP 
(Appendix 6). The number of imputations used for the derivation of the attributable estimand 
will be between 100 and 1000. Work by Seaman, White and Leacy (2014) and Cro (2017) show 
that Rubin’s rules can be validly used in conjunction with so called control-based multiple 
imputation methods, of which our attributable analysis is one type. Given these results we 
believe the attributable analysis to be conservative from a Type I error control perspective. 
Sensitivity analyses will be conducted to assess robustness of the analyses to missing data (See 
Section 6.4.4.4).

PT010007: 
The change from baseline in morning pre-dose trough FEV1 over 52 weeks (Weeks 4 to 52) and 
at each post-baseline visit will be analyzed for the efficacy estimand with the Japanese mITT 
Population using an RM linear mixed model. The model will include treatment, visit, and 
treatment by visit interaction, and ICS use at screening as categorical covariates and baseline 
FEV1, baseline eosinophil count, and percent reversibility to Ventolin HFA as continuous 
covariates. Baseline is defined as the mean of the non-missing -60 minute and -30 minute values 
obtained prior to dosing at Visit 4. An unstructured correlation matrix will be used to model 
variability across time within each subject. If the UN model fails to converge, then an AR(1) 
structure will be used instead. In an AR(1) model, subject will be included as a random effect. 
Two-sided p-values and point estimates with two-sided 95% CIs will be produced for each 
treatment difference. The analysis will assess the treatment effects over the entire 52 weeks of 
treatment, i.e. subject data from the first 24 weeks of Study PT010006 will be included in the 
analyses (Table and Figure 2.1.2 and Figures 2.1.2.1 and 2.1.2.2 for the Japanese mITT 
Population). 
6.4.4.2
FEV1 AUC0-4
FEV1 AUC0-4 will be analyzed for PT010006.  
FEV1 AUC0-4 is the area under the curve for the change from baseline for FEV1 and is calculated 
using the trapezoidal rule. The AUC will be normalized by converting it into a weighted average, 
which will be accomplished through dividing by the time in hours from dosing to the last 
measurement included (typically 4 hours). Only one non-missing post-dose value is required for 
the calculation of AUC. Actual time from dosing will be used if available; otherwise scheduled 
time will be used.  
The differences between treatment groups in FEV1 AUC0-4 over 24 weeks (i.e. Weeks 4 to 24) 
(primary for EU/ Canada), over Weeks 12 to 24 (secondary for Japan/China), at Week 24 
(primary for US), and at Day 1 and each post-randomization visit (“other” endpoint), will be 
evaluated using an RM linear mixed model with baseline FEV1, percent reversibility to Ventolin 
HFA, and baseline eosinophil count as continuous covariates and treatment, visit, treatment by 
visit interaction, and ICS use at Screening as categorical covariates. Two-sided p-values and 
point estimates with two-sided 95% CIs will be produced for each treatment difference of 
interest (Tables and Figures 2.1.8 to 2.1.11, and Figures 2.1.12.1to 2.1.12.8 for the efficacy, 
attributable, treatment policy, and per protocol estimands, respectively). Additional figures will 
display FEV1 AUC0-4 by completion vs. discontinuation patterns for the efficacy estimand, the 
attributable estimand, and the treatment policy estimand (Figures 2.1.12.9 to 2.1.12.12). 
All comparisons will be for superiority except that the comparison of BFF MDI to Symbicort 
TBH will be for non-inferiority and will use a margin of -75 mL for the lower bound of the 95% 
CI for the treatment difference. The primary analysis will be conducted using the efficacy 
estimand except for the non-inferiority comparisons of BFF MDI vs. Symbicort TBH, for which 
the per protocol estimand will be the primary population.

For the attributable estimand of FEV1 AUC0-4 (for the analysis at Week 24, the analysis over 
Weeks 12-24, and the analysis over 24 weeks), data that are missing due to treatment 
discontinuation will be imputed in a similar manner as in the attributable estimand for morning 
pre-dose trough FEV1 in Section 6.4.4.1 above. 
Sensitivity analyses will be conducted to assess robustness of the analyses to missing data (See 
Section 6.4.4.4). 
Study PT010007 did not have post-dose spirometry and therefore the analysis of FEV1 AUC0-4 is 
not possible. 
6.4.4.3
Assumptions Checks and Removal of Outliers in Sensitivity Analyses 
In general, the distribution of spirometry measures is well-approximated by a normal 
distribution. Under some circumstances (for example during a COPD exacerbation unrelated to 
treatment), atypical values can arise. Such values may disproportionately affect model-based 
estimates of the fixed effect and variance parameters. Prior to database lock and unblinding, the 
change from baseline values for efficacy endpoints will be examined as part of data quality 
management. This may include production of normal probability plots, kernel density estimates, 
and normal order outlier statistics. Based on this blinded evaluation, if atypical values are 
identified, nonparametric methods or data transformations (e.g. logarithmic or normal rank 
transformation) will be considered. If erroneous values are detected, every effort will be made to 
correct them prior to database lock. If these values cannot be corrected, they will be considered 
for removal from analysis. These analyses will be conducted if warranted to demonstrate the 
robustness of the primary and secondary results and reported in the Statistical Methods Appendix 
to the clinical study report (CSR). 
The assumption of normality in the change from baseline in the morning trough FEV1 data will 
be checked by visually inspecting the distribution of the residuals. Also, model fit and the 
assumption of homogeneity of variance will be verified by inspection of scatter plots of predicted 
vs. residuals, residuals vs. treatment, residuals vs. ICS use (yes/no), and by box plots of residuals 
for model variables with a potential effect on variance (treatment, visit, and ICS use). Plots for 
scaled (marginal) residuals will be prepared (option=VCIRY on the model statement and ODS 
graphics option allows the production of plots using these residuals). As a sensitivity analysis, if 
appropriate, the linear RM model analysis will be conducted by allowing for heterogeneity of 
variance between treatments, visits (if unstructured correlation matrix fail to converge), and/or 
ICS use categories (yes/no). Note that the unstructured correlation matrix structure allows for 
heterogeneity among the visits. 
 
Some further assumptions checks are mentioned in the Details Appendix to this SAP.

Sensitivity Analyses for Missing Data 
Sensitivity analyses will be conducted for FEV1 and AUC0-4 to evaluate the robustness of the 
primary analysis findings to missing data.  
Robustness of results to missing data will be explored using tipping point analyses (Ratitch 
2013).  
For the attributable estimand for morning pre-dose trough FEV1 and FEV1 AUC0-4, data that are 
missing due to treatment discontinuation will be imputed based on the 5th percentile of the GFF 
and BFF reference arms’ distribution if the reason is reasonably attributable to tolerability or lack 
of efficacy (see Sections 6.4.4.1 and 6.4.4.2). Other missing data are to be imputed using the 
observed data model. 
 
Analyses of the treatment policy estimand will be conducted in the ITT Population where all 
observed data will be utilized regardless of whether subjects remain on randomized treatment. A 
sensitivity analysis will be conducted where missing data in the treatment arm are imputed with 
the benefit of treatment decremented by up to 500 mL until the p-value  0.05. 
The following table summarizes the multiple imputation-based sensitivity analyses under the 
PMM (pattern mixture model) framework that will be undertaken,

treatment discontinuation 
is due to tolerability or 
lack of efficacy of study 
drug (as in the primary 
analysis of this estimand). 
Otherwise, all missing data 
are imputed using the 
observed data model 
except that for subjects in 
the treatment arm (not the

are imputed with the 
change from baseline in

with the change from 
baseline in the treatment 
arm decremented by up to 
500 mL until the p-value 

MNAR = Missing not at random. Missingness determined to be potentially MNAR will be defined and documented 
in the BDRM minutes prior to unblinding. The tipping point will be shown to at least a precision of 10 mL. Imputed 
values may not be impossible values – i.e. changes from baseline that would imply a negative FEV1 value. Thus the 
values will be imputed from a truncated distribution. 
The primary analysis is for the efficacy estimand, which includes data collected up until the time 
of discontinuation of treatment. The efficacy estimand quantifies the difference in outcomes for 
all patients as if they continued on their initially randomized treatment. The primary analysis 
uses a linear mixed model and assumes that all missing data are MAR or MCAR (missing 
completely at random).  
Although the analysis for the attributable estimand starts with the same amount of missingness, 
less remains after imputation for missingness deemed attributable to the treatments is performed. 
These remaining missing data are imputed using the observed data model in the main analysis 
under the assumption of MAR. More detail about the computation of the attributable estimand is 
provided in subsequent sections and in the Details Appendix to this SAP. 
Tipping-point analyses will be conducted to examine the impact of varying the treatment mean 
for missing data in subjects who discontinue BGF MDI. Multiple imputation (MI) techniques

will be used to impute the missing data for these patients by varying the mean in the treatment 
arm. The change from baseline in the treatment arm will be decremented by up to 500 mL until 
the p-value for the comparison of treatment to comparator becomes  0.05. A total of 10 
imputations will be used for each set of tipping point analyses. This imputation technique will be 
applied in sensitivity analyses as described below. 
Tipping Point Analyses of the Primary Estimand: 
Tipping Point #1: this first set of analyses will impute diminished effects only for 
subjects on BGF MDI whose missing data are determined to be MNAR.  
Tipping Point #2: this analysis will impute diminished effects for all missing data in the 
BGF MDI arm.  
Note that for both tipping point analyses, all other missing data will be imputed using the 
observed data model. 
Tipping Point Analysis of the Attributable Estimand: 
For the attributable estimand, by definition, missing data in all arms due to tolerability and lack 
of efficacy are already imputed based on the 5th percentile of the reference arms’ distribution, 
therefore the remaining missing data imputed using the observed data model in the main analysis 
are likely MAR or MCAR. Hence, there is no need to conduct a tipping analysis like #1 planned 
for the efficacy estimand. A tipping point analysis like #2 will be conducted where the non-
attributable missing data will be imputed using progressively diminished effects. 
Tipping Point Analysis of the Treatment Policy Estimand: 
For the treatment policy estimand, a tipping point analysis like #2 will be conducted where 
missing data in the treatment arm will be imputed using progressively diminished effects. 
In all of these analyses, the imputed values that would have been seen are then combined with 
the observed values to provide a complete dataset. These data are then analyzed using the same 
linear mixed model used for the primary analysis. This analysis is repeated multiple times and 
the results are combined using Rubin’s formulae [Rubin, 1987].  
For the tipping point analyses, tables giving results for each progressively diminished effect will 
be produced. Figures of delta (decrement in treatment effect) versus p-values will also be 
produced. Details of the sensitivity analyses are discussed in the Statistical Methods Appendix to 
the CSR. 
Cumulative Responder Analysis 
Additional sensitivity analyses will be implemented based on a cumulative responder approach 
(Farrar et al., 2006) for the change from baseline in morning pre-dose trough FEV1 over Weeks

12-24, over 24 weeks, and at Week 24 (Tables 2.1.14.1 to 2.1.14.3 for the efficacy estimand, 
Tables 2.1.14.1a to 2.1.14.3a for treatment policy estimand), and change from baseline in FEV1 
AUC0-4 over 24 weeks and at Week 24 (Tables 2.1.14.4 and 2.1.14.5 for the efficacy estimand 
and Tables 2.1.14.4b and 2.1.14.5b for the treatment policy estimand). A cumulative distribution 
plot by treatment arm will also be produced. The observed change from baseline in morning pre-
dose trough FEV1 over Weeks 12-24 (over 24 weeks and at Week 24) will be plotted on the X 
axis, while the proportion of responders (subjects that equal or exceed that level of change) will 
be plotted on the Y axis (Figures 2.1.14.1 to 2.1.14.3 for the efficacy estimand, Figures 
2.1.14.1a and 2.1.14.3a for the treatment policy estimand), and a cumulative proportion of 
responders plot for change from baseline in FEV1 AUC0-4 over 24 weeks and at Week 24 
(Figures 2.1.14.4 and 2.1.14.5 for the efficacy estimand and Figures 2.1.14.4a and 2.1.14.5a for 
the treatment policy estimand). Subjects without post-baseline data or who discontinue treatment 
for any reason will be considered non-responders in the analysis. For display purposes only, the 
range of the X axis will be from -1 to +1 liters [L] by increments of 0.01 liters in order to avoid 
the undue influence of outlying values. The cumulative responder curves for each treatment will 
then be compared pairwise using Kolmogorov-Smirnov tests. Cumulative responder analyses for 
the attributable estimand will not be performed because they are not well defined: methodology 
to apply Rubin’s rules for combining multiply imputed data for such an analysis is not readily 
available. 
6.4.5
Analysis of Secondary Efficacy Variables 
The following variables appear as secondary for 1 or more registration approaches: morning pre-
dose trough FEV1 over 24 Weeks, FEV1 AUC0-4 over Weeks 12-24, peak FEV1, TDI focal score 
(at Week 24, over Weeks 12-24, and over 24 weeks), rescue Ventolin HFA usage over 24 weeks, 
SGRQ total score over Weeks 12-24 and over 24 weeks, percentage of subjects achieving an 
MCID of 4 units or more in SGRQ total score at Week 24, RS-Total score over 24 weeks, time 
to CID, the rate of moderate or severe COPD exacerbations, and time to onset. Multiplicity will 
be controlled for the secondary variables as described in Section 6.4.11. The main analysis for 
secondary endpoints will use the efficacy estimand. The treatment policy estimand will include 
all post-treatment discontinuation data and will serve as a sensitivity analysis. The attributable 
estimand will also be estimated as a sensitivity analysis for the secondary endpoints with the 
exception of time of onset on Day 1.  
For the attributable estimand for continuous variables, namely, rescue Ventolin use, the SGRQ 
total score, and the RS-Total Score, missing data are imputed based on the 95th percentile of the 
reference arms’ distribution if the reason for discontinuation is attributable to lack of efficacy 
or/tolerability, while for TDI and Peak FEV1, missing data are imputed based on the 5th 
percentile of the reference arms’ distribution if the reason for discontinuation is attributable to 
lack of efficacy or/tolerability. All other missing data will be imputed using the observed data 
model. The variance used for the multiple imputation is described in the Details Appendix to this 
SAP. Time to onset on Day 1 is excluded since there is anticipated to be very little missing data 
at this early time point. The imputation for the rate of moderate or severe COPD exacerbations 
and time to CID is described in the respective sections below.

The non-inferiority margins will be set to 0.75 for TDI, 10% for achievement of MCID in 
SGRQ, 75 mL for peak change from baseline in FEV1, and -1.5 for E-RS total score. 
6.4.5.1
Transition Dyspnea Index 
The TDI is collected in Study PT010006 only. 
 
Assessments of dyspnea will be obtained using the BDI/TDI (where BDI is the Baseline Dyspnea 
Index). The BDI/TDI questionnaire can be found in Protocol Appendix 10.  
 
At Randomization (Visit 4), the severity of dyspnea at baseline will be assessed using the BDI. 
BDI components are functional impairment, magnitude of task, and magnitude of effort (Listing 
6.1.6). The possible range of values for each BDI component score is 0 (very severe impairment) 
to 4 (no impairment). The BDI component scores are summed to determine the BDI focal score 
(0 to 12) (i.e., the lower the score, the worse the severity of dyspnea). 
At subsequent visits (as per Schedule of Events: see of the Schedule of Events in the PT010006 
protocol), change from baseline will be assessed using the TDI. TDI components include: 
Change in Functional Impairment, Change in Magnitude of Task, and Change in Magnitude of 
Effort (Listing 6.1.6). The TDI component score ranges from -3 (major deterioration) to +3 
(major improvement). The sum of all component scores yields the TDI focal score (-9 to +9) 
(i.e., the lower the score, the more deterioration from baseline).  
The difference between treatment groups in TDI focal score over Weeks 12-24 and over 24 
weeks and at each post-randomization visit will be analyzed using a similar RM approach as for 
the primary endpoint, but using BDI instead of baseline FEV1 in the model, and adding baseline 
post-bronchodilator percent predicted FEV1 as a continuous covariate. Thus, the model will 
include treatment, visit, treatment by visit interaction, and ICS use at Screening as categorical 
covariates and BDI, baseline eosinophil count, percent reversibility to Ventolin HFA and 
baseline post-bronchodilator percent predicted FEV1 as continuous covariates. The treatment 
comparisons at each visit are considered to be “other” endpoints. Data from all study treatments 
will be included in the modeling. Scoring and handling of missing items will be conducted in 
accordance with the user’s guide for the TDI score. Two-sided p-values and point estimates with 
2-sided 95% CIs will be produced for each treatment difference (Tables and Figures 2.2.1 for the 
efficacy estimand).  
Analyses in the attributable estimand, the treatment policy estimand, and the per protocol 
estimand over Weeks 12-24 and over 24 Weeks will be conducted as supportive (Tables and 
Figures 2.2.2, 2.2.3 and 2.2.5, respectively). 
The attributable estimand will be computed in a similar manner as the attributable estimand is 
computed for change from baseline in morning pre-dose trough FEV1 at Week 24 as described in 
Section 6.4.4.1.

All comparisons will be for superiority except that the comparison of BFF MDI to Symbicort 
TBH will be for non-inferiority rather than superiority and will use a margin of -0.75 for the lower 
bound of the two sided 95% CI for the treatment difference. The main analysis will be conducted 
using the efficacy and attributable estimands except for the non-inferiority comparisons of BFF 
MDI vs. Symbicort TBH, for which the per protocol estimand analysis will be main analysis. 
In addition, the difference between treatments for the individual components of the TDI (as 
“other” endpoints): functional impairment, magnitude of task, and magnitude of effort will each 
be analyzed over 24 weeks, over Weeks 12-24, and at each post-baseline visit using the same 
modeling approach as for the TDI total score (Table 2.2.7 and Figures 2.2.7.1-2.2.7.3 for the 
functional impairment, magnitude of task, and magnitude of effort for the efficacy estimand).  
Furthermore, as supportive analyses, responder analyses will be performed (for the TDI focal 
score) where responders are defined as subjects with a response of 1.0 point or more 
(corresponding to at least a minor improvement) on average over 24 weeks and on average over 
Weeks 12-24. Logistic regression with SAS PROC GENMOD will be used to compare the 
treatment groups with BDI, baseline eosinophil count, post-bronchodilator percent predicted 
FEV1, and percent reversibility to Ventolin HFA as continuous covariates and treatment, and ICS 
use at Screening as categorical covariates. P-values and odds ratios with 95% CIs will be 
produced for each of the four treatment comparisons (Table 2.2.13 for the efficacy estimand). 
For the TDI, at each visit, if a response to any of the three questions is missing, then the focal 
score will also be considered missing. For the TDI responder analyses, subjects without post-
baseline data or who discontinue treatment for any reason will be considered to be non-
responders. 
TDI and BDI data will be listed in Listing 6.1.6. 
6.4.5.2
Peak FEV1
Peak FEV1 will be included in the analyses of the efficacy, attributable, treatment policy, and per 
protocol estimands as long as there is at least one non-missing post-dose value. 
Peak FEV1 will be analyzed for Study PT010006. 
The peak change from baseline in FEV1 within 4 hours post-dosing (assessed within a visit) over 
Weeks 12-24 (Japanese/China Approach), over 24 weeks (EU and Canada approaches), and at 
Week 24 (US Approach) will be analyzed and summarized similarly to morning pre-dose trough 
FEV1. The peak change from baseline on Day 1 and at each post randomization visit will also be 
analyzed. Peak FEV1 will be included in efficacy, attributable, and treatment policy estimand 
analyses as long as there is at least one non-missing post-dose value during the first 4 hours post-
dose. For the per protocol estimand analysis, Peak FEV1 will be calculated if there are at least 
two non-missing FEV1 data-points during the first 4 hours post-dose (Tables and Figures 2.3.1,
2.3.2, 2.3.3, and 2.3.5 for the efficacy, attributable, treatment policy, and per protocol estimands, 
respectively).

The attributable estimand will be computed in a similar manner as the attributable estimand is 
computed for change from baseline in morning pre-dose trough FEV1 at Week 24 as described in 
Section 6.4.4.1.  
Additional sensitivity analyses will be implemented based on a cumulative responder approach 
as described in Farrar 2006 for the peak change from baseline in FEV1 within 4 hours post-dose 
over 24 Weeks (Table 2.3.4 for the efficacy estimand). A cumulative distribution plot by 
treatment arm (Farrar et al., 2006) will also be produced. The observed peak change from 
baseline in FEV1 will be plotted on the X axis, while the proportion of responders (subjects that 
equal or exceed that level of change) will be plotted on the Y axis (Figure 2.3.4 for the efficacy 
estimand). Subjects without post-baseline data or who discontinue treatment for any reason will 
be classified as non-responders. For display purposes only, the range of the X axis will be from -
1 to +1 liters [L] by increments of 0.01 liters in order to avoid the undue influence of outlying 
values. The cumulative responder curves for each treatment will then be compared pairwise 
using Kolmogorov-Smirnov tests. Cumulative responder analyses for the attributable estimand 
will not be performed because they are not well defined: methodology to apply Rubin’s rules for 
combining multiply imputed data for such an analysis is not readily available. 
Tipping Point Analyses for Peak Change from Baseline in FEV1 within 4 hours Post-Dose at 
Week 24  
Robustness of results to missing data will be explored using tipping point analyses (Ratitch 
2013). A brief overview of the approach is summarized in the table below. Details of the 
methods are similar to sensitivity analyses of FEV1 and AUC0-4 (found in Sections 6.4.4.4 and in 
the Details Appendix to this SAP), but with the model for peak change from baseline in FEV1 
described above. Multiple-imputation results will be combined using Rubin’s formulae [Rubin, 
1987]. Details of the methods may be found in the Details Appendix to this SAP.

St. George’s Respiratory Questionnaire 
The SGRQ is collected in Study PT010006. 
The SGRQ will be used to provide the health status/health-related QoL measurements in this 
study (see PT010006 Protocol Appendix 10). The SGRQ contains 50 rated items divided into 
three domains: "Symptoms" concerned with respiratory symptoms, their frequency, and severity; 
"Activity" concerned with activities that cause or are limited by breathlessness; and "Impacts" 
which covers a range of aspects concerned with social functioning and psychological 
disturbances resulting from airway disease. Individual items of SGRQ data will be listed 
(Listings 6.1.7 for All Subjects Randomized). 


BGF MDI/GFF MDI/BFF MDI 
Protocols PT010006 and PT010007

A score will be calculated for each component and a "Total" score will also be calculated 
(Listings 6.1.9 for All Subjects Randomized). In each case, the lowest possible value is zero and 
the highest is 100. Higher values correspond to greater impairment of QoL. 
The difference between treatment groups in the change from baseline in SGRQ over 24 weeks 
and over Weeks 12 to 24 will be evaluated using a similar RM approach as for TDI focal score, 
but adding country as a covariate, and with baseline SGRQ score replacing BDI in the model. 
Thus the model will include treatment, visit, treatment by visit interaction, ICS use at Screening, 
and country as categorical covariates and baseline SGRQ score, baseline eosinophil count, 
percent reversibility to Ventolin HFA and baseline post-bronchodilator percent predicted FEV1 
as continuous covariates. Scoring and handling of missing items will be conducted in accordance 
with the user’s guide for the SGRQ. Each response is to be given a unique empirically derived 
weight between 0 and 100, the weights of all responses are then summed up and divided by the 
maximum possible score and expressed as a percentage. Missing SGRQ total scores will not be 
imputed. Two-sided p-values and point estimates with 2-sided 95% CIs will be produced for 
each treatment difference. The comparison of BFF MDI to Symbicort TBH will be for 
non-inferiority rather than superiority and will use a margin of 3 units for the upper bound of the two 
sided 95% CI for the treatment difference. 
The main analysis of the SGRQ will be for the efficacy estimand. Supportive analyses will use 
the attributable estimand, the treatment policy estimand, and per protocol estimand over Weeks 
12-24 and over 24 Weeks (Tables and Figures 2.4.1, 2.4.3, 2.4.4, and 2.4.5 for the efficacy, 
attributable, treatment policy, and per protocol estimands, respectively).  
The attributable estimand (for the analysis of the change from baseline in total SGRQ score) will 
be computed in a similar manner as the attributable estimand is computed for change from 
baseline in morning pre-dose trough FEV1 at Week 24 as described in Section 6.4.4.1 except that 
the 95th percentile will be used instead of the 5th percentile. 
As additional supportive analyses (i.e. as other efficacy endpoints), the difference between 
treatments at each of the individual visits will be evaluated and summarized (Tables and Figures
2.4.1, 2.4.4, and 2.4.5). Individual domains of the SGRQ (as “other” endpoints) will also be 
analyzed in a similar fashion as the total score (Tables 2.4.7 for the efficacy estimand).  
Responder analyses will be performed where responders are defined as subjects with an 
improvement of (i.e. a decrease in the total SGRQ score of) 4.0 points at Week 24 (secondary 
endpoint for US Approach), and on average over 24 weeks (EU and Canada Approaches) and 
Weeks 12-24 (Japan/China Approach). For the SGRQ responder analyses, subjects without post-
baseline data or who discontinue treatment for any reason will be considered non-responders. 
Logistic regression will be used to compare the treatment groups with baseline SGRQ Score, 
baseline eosinophil count, baseline post-bronchodilator percent predicted FEV1, and percent 
reversibility to Ventolin HFA as continuous covariates, and treatment, country, and ICS use at 
Screening as categorical covariates. P-values and odds ratios with 95% CIs will be produced for 
each treatment comparison (Table 2.4.13 for the efficacy estimand and Tables 2.4.14, 2.4.15, and

2.4.16 for the attributable estimand, the treatment policy estimand, and the per protocol 
estimand, respectively). 
The attributable estimand (for responder analysis of SGRQ) will be computed as follows. First, 
multiple imputations will be performed on the continuous total SGRQ scores in a similar manner 
as for the attributable estimand that is computed for change from baseline in morning pre-dose 
trough FEV1 (Section 6.4.4.1), except that the 95th percentile will be used instead of the 5th 
percentile. After that, it will be determined whether the subject has attained the MCID. The 
analysis will proceed using logistic regression as described above, followed by combining of 
results across the multiple imputations using the formulae of Rubin [Rubin, 1987]. 
Additional sensitivity analyses will be implemented based on a cumulative responder approach 
as described in Farrar 2006 for the change from baseline in SGRQ score over 24 weeks (Table
2.4.2 for the efficacy estimand). A cumulative distribution plot by treatment arm (Farrar et al., 
2006) will also be produced. The observed change from baseline in SGRQ over 24 weeks will be 
plotted on the X axis, while the proportion of responders (subjects that equal or exceed that level 
of change) will be plotted on the Y axis (Figure 2.4.2 for the efficacy estimand). Subjects 
without post-baseline data or who discontinue treatment for any reason will not be considered 
non-responders at all values. For display purposes only, the range of the X axis will be from -8 to 
+8 by increments of 0.1 in order to avoid the undue influence of outlying values. The cumulative 
responder curves for each treatment will then be compared pairwise using Kolmogorov-Smirnov 
tests. Cumulative responder analyses for the attributable estimand will not be performed because 
it is not well defined. 
Tipping Point Analyses for Percentage of Subjects achieving an MCID of 4 Units or More in 
SGRQ Total Score at Week 24  
Robustness of results to missing data will be explored using tipping point analyses (Ratitch 
2013). A brief overview of the approach is summarized in the table below. Details of the 
methods are similar to sensitivity analyses of FEV1 and AUC0-4 (found in Section 6.4.4.4 and in 
the Details Appendix to this SAP), but with the model for SGRQ total score described above. 
Multiple-imputation results will be combined using Rubin’s formulae [Rubin, 1987]. Details of 
the methods may be found in the Details Appendix to this SAP.

The multiple imputation will be applied to the continuous total SGRQ scores within the already-
stated repeated-measures analysis framework for total SGRQ score. Missing values will first be 
imputed for the missing total SGRQ scores prior to the computation of whether the subject has 
attained the MCID (for the sensitivity analysis). The analysis using the imputed data will proceed 
using logistic regression as described above, followed by a combining of results across the

Rescue Ventolin HFA Use 
PT010006: 
The number of puffs of rescue Ventolin HFA taken in the previous 12 hours since the previous 
(AM or PM) dose will be recorded in the subject diary in the morning and evening. The mean 
daily number of puffs of rescue Ventolin HFA used by subjects during the study will be 
calculated overall and for each of the 4-week intervals during the treatment period and provided 
in a diary data listing (Listing 6.1.3 for All Subjects Randomized). Diary data recorded during 
the last 7 days of the 10- to 14-day Screening Period will be used to calculate the baseline. For 
every interval of time over which the mean number of puffs of rescue will be calculated, records 
with missing values will be ignored in both the numerator and denominator. As such, the 
denominator will be adjusted based on the number of days (including half days) with 
non-missing values. 
That is, the mean daily number of puffs of daytime rescue use (M_DT) will be set to the total 
number of daytime puffs divided by the number of half-days when daytime rescue use was 
recorded. The mean daily number of puffs of nighttime rescue use (M_DN) will be set to the 
total number of nighttime puffs divided by the number of half-days when the nighttime rescue 
use was recorded. The mean daily rescue use (puffs) is then two multiplied by the mean of 
M_DT and M_DN. 
The difference between treatment groups in the change from baseline in rescue Ventolin HFA 
usage over 24 weeks will be evaluated using a linear RM analysis of covariance (ANCOVA) 
model which will include treatment, 4-week time interval (Interval 1 – Interval 6), treatment by 
time-interval interaction, and ICS use at Screening as categorical covariates, and baseline rescue 
Ventolin HFA use, baseline eosinophil count, percent reversibility to Ventolin HFA, and 
baseline post-bronchodilator percent predicted FEV1 as continuous covariates. A UN matrix will 
be used to model additional autocorrelation within subject. If the UN model fails to converge, an 
AR(1) structure will be used instead. In the AR(1) model, subject will be included as a random 
effect. Contrasts will be used to obtain estimates of the treatment differences over the entire 
24 weeks. Two-sided p-values and point estimates with two-sided 95% CIs will be produced for 
each of the four treatment differences. The comparison of BFF MDI to Symbicort TBH will be for 
non-inferiority rather than superiority and will use a margin of 0.75 puffs/day for the upper bound of 
the two sided 95% CI for the treatment difference. The main analysis will be conducted using the 
efficacy estimand (Table and Figure 2.5.1) restricted to the Rescue Ventolin User (RVU) 
Population. Supportive analyses will use the attributable, the treatment policy estimand, and the 
per protocol estimand (Tables and Figures 2.5.3 and 2.5.5) restricted to the RVU Population. 
Other supportive analyses will use the efficacy estimand not restricted to the RVU Population 
and the treatment policy estimand not restricted to the RVU Population (Tables and Figures
2.5.6 and 2.5.7).  
The attributable estimand (for the analysis of average daily rescue Ventolin HFA use) will be 
computed in a similar manner as the attributable estimand is computed for change from baseline

in morning pre-dose trough FEV1 at Week 24 as described in Section 6.4.4.1 except that the 95th 
percentile will be used instead of the 5th percentile. 
As supportive analyses, the treatment difference for each 4-week interval and over Weeks 12 to 
24 will be evaluated and summarized. Additionally, as supportive analyses, daytime rescue 
Ventolin® HFA use and night-time rescue Ventolin HFA use will be evaluated and summarized 
in a similar fashion. Two-sided p-values and point estimates with 2-sided 95% CIs will be 
produced for each treatment difference (Tables and Figures 2.5.9 and 2.5.13 for the efficacy 
estimand restricted to the RVU Population).  
Additional sensitivity analyses will be implemented based on a cumulative responder approach 
as described in Farrar 2006 for the change from baseline in average daily rescue medication over 
24 weeks (Table 2.5.1a for the efficacy estimand). A cumulative distribution plot by treatment 
arm (Farrar et al., 2006) will also be produced. The observed change from baseline in average 
daily rescue medication over 24 weeks will be plotted on the X axis, while the proportion of 
responders (subjects that equal or exceed that level of change) will be plotted on the Y axis 
(Figure 2.5.1a for the efficacy estimand. Subjects without post-baseline data or who discontinue 
treatment for any reason will be considered non-responders for all values. For display purposes 
only, the range of the X axis will be from the 1st percentile to the 99th percentile irrespective of 
treatment in order to avoid the undue influence of outlying values. The cumulative responder 
curves for each treatment will then be compared pairwise using Kolmogorov-Smirnov tests. 
Cumulative responder analyses for the attributable estimand will not be performed because they 
are not well defined. 
Tipping Point Analyses for Rescue Ventolin HFA Use Over 24 Weeks  
Robustness of results to missing data will be explored using tipping point analyses (Ratitch

6.4.5.5
RS-Total Score 
PT010006: 
The EXACT is a 14-item patient reported outcome (PRO) instrument from the daily diary which 
will be used to measure the effect of treatment on exacerbations, and on the severity of 
respiratory symptoms. Mean change from baseline in the daily EXACT Total Score, the 11-item 
RS-Total Score, as well as 3 subscale scores, RS-Breathlessness, RS-Cough and Sputum, and 
RS-Chest Symptoms, will be calculated over each post-randomization 4-week interval of the 24-
week Treatment Period. Higher scores indicate a more severe condition. The last 7 days of the 10 
to 14 day Screening Period will be used to calculate the baseline. The mean change from 
baseline in the EXACT Total Score, RS-Total Score, RS-Breathlessness, RS-Cough and Sputum, 
and RS-Chest Symptoms over each 4-week interval will be analyzed using a similar RM model 
as for TDI to estimate treatment effects over 24 weeks and over Weeks 12 to 24, but using the 
corresponding baseline mean score instead of the BDI as a covariate (Tables and Figures 2.6.1, 
2.6.3, 2.6.4, and 2.6.5 for the efficacy estimand, the attributable estimand, and the treatment 
policy estimand, and Tables 2.6.13 and 2.6.14 for the efficacy estimand and the efficacy 
estimand in the Japanese mITT Population). The analyses on the attributable estimand, treatment 
policy estimand, and per protocol estimand will pertain to the RS-Total Score only. Instead of 
visit, the number of the relevant respective 4-week interval (Interval 1 to Interval 6) will be used 
as a categorical covariate in the model. Thus the model will include treatment, time interval, 
treatment by time-interval interaction, and ICS use at Screening as categorical covariates and 
baseline score, baseline eosinophil count, percent reversibility to Ventolin HFA and baseline 
post-bronchodilator percent predicted FEV1 as continuous covariates. An unstructured 
correlation matrix will be used to model additional autocorrelation within subject. If the UN 
model fails to converge, then an AR(1) structure will be used instead. In the AR(1) model, 
subject will be included as a random effect. The RS-Total score over 24 weeks is a secondary 
efficacy endpoint. The EXACT Total score, RS-Total score and the RS subscale scores are 
“other” endpoints. EXACT data will be listed in Listing 6.1.5. The analysis of RS-Total score 
will be secondary for the EU only. 
The attributable estimand (for the analysis of RS-Total score) will be computed in a similar 
manner as the attributable estimand is computed for change from baseline in morning pre-dose 
trough FEV1 at Week 24 as described in Section 6.4.4.1 except that the 95th percentile will be 
used instead of the 5th percentile. 
Additional sensitivity analyses will be implemented based on a cumulative responder approach 
as described in Farrar 2006 for the change from baseline in daily RS-Total Score over 24 weeks 
(Table 2.6.1a for the efficacy estimand). A cumulative distribution plot by treatment arm (Farrar 
et al., 2006) will also be produced. The observed change from baseline in mean daily RS-Total 
score over 24 weeks will be plotted on the X axis, while the proportion of responders (subjects 
that equal or exceed that level of change) will be plotted on the Y axis (Figure 2.6.1a for the 
efficacy estimand). Subjects without post-baseline data or who discontinue treatment for any 
reason will be considered non-responders for all values. For display purposes only, the range of 
the X axis will be from the 1st percentile to the 99th percentile irrespective of treatment in order

to avoid the undue influence of outlying values. The cumulative responder curves for each 
treatment will then be compared pairwise using Kolmogorov-Smirnov tests. Cumulative 
responder analyses for the attributable estimand will not be performed because they are not well 
defined. 
PT010007: 
The mean change from baseline in RS-Total Score, EXACT Total Score, RS-Breathlessness, RS-
Cough and Sputum, and RS-Chest Symptoms will be summarized by treatment group over 52

6.4.5.6
Time to Onset of Action Assessed Using FEV1 on Day 1 
This analysis will be conducted for PT010006. 
The onset of action will be determined for each treatment using the post-dosing FEV1 
assessments from Day 1. The onset of action for each product (BGF MDI, GFF MDI, and BFF 
MDI) will be defined as the first time point where the mean change from baseline exceeds 100 
mL. Supportive analyses may be conducted using alternatively definitions of onset of action. The 
resulting tables and figures are Table and Figure 2.7.1 for the efficacy estimand. 
6.4.5.7
Other Spirometry Endpoints 
Analyses of other endpoints will be performed for the efficacy estimand only.  
PT010006: 
The analysis for between-treatment comparisons of changes from baseline in morning pre-dose 
trough FEV1 over 24 weeks, over Weeks 12-24 and at each post-randomization visit through 
Week 24 has already been described in Section 6.4.4.1 (Tables and Figures 2.1.1, and 2.1.3). 
Analyses for FEV1 AUC0-4 over 24 weeks, over Weeks 12-24, and at each post-randomization 
visit have been described in a similar manner in Section 6.4.4.2 (Table and Figure 2.1.9 for 
efficacy estimand). Peak change from baseline within 4 hours in FEV1 over 24 weeks, over 
Weeks 12 to 24, and at Day 1 and at each post-randomization visit where measured through 
Week 24 will be estimated and compared between treatment groups using a linear mixed RM 
model with the same model as pre-dose trough FEV1 (Table and Figure 2.3.1 for the efficacy).  
Similar analyses will be conducted for FVC, PEFR, and FEF25-75 over 24 weeks, over Weeks 12 
to 24, and at each post-randomization visit where measured for the mITT and ITT Populations, 
respectively. The baseline covariate for each model will be endpoint-specific (Tables and 
Figures 2.8.1 to 2.8.14 for change from baseline in morning pre-dose trough FVC, PEFR, and 
FEF25-75; Tables and Figures 2.9.1 to 2.9.14 for peak change from baseline within 4 hours for 
FVC, PEFR, and FEF25-75; Tables and Figures 2.10.1 to 2.10.14 for FVC AUC0-4, PEFR AUC0-4, 
and FEF25-75 AUC0-4). The analyses for change from baseline at each post-dose time point in 
FEV1, FVC, PEFR, and FEF25-75 on Day 1 will be provided (Tables and Figures 2.7.1 and 2.7.3

for FEV1 and 2.11.7 to 2.11.19 for FVC, PEFR, and FEF25-75, respectively; Listings 6.3.1 to 6.3.7 
for the efficacy estimand). 
On Day 1 during the first four hours post-dosing and by time point, the proportion of subjects 
achieving an improvement from baseline in FEV1 using different thresholds (i.e., 10%, 12%, 
100 mL, 200 mL, and “12% and 200 mL”) will be estimated for each treatment. Subjects 
without post-baseline data will not be considered in the analysis. Logistic regression, performed 
with SAS PROC GENMOD, will be used to compare the treatments, adjusting for baseline 
FEV1, reversibility to Ventolin HFA, and baseline eosinophil count as continuous covariates, and 
ICS use at Screening as a categorical covariate. The odds ratio for treatment will be determined, 
along with the Wald two-sided 95% CI. The Wald chi-square test will be used to calculate p-
values for comparisons between treatments (Tables and Figures 2.12.1, 2.12.3, 2.12.4, 2.12.5, 
and 2.12.7 for the efficacy estimand). 
PT010007: 
The analysis for changes from baseline in morning pre-dose trough FEV1 over 52 weeks (Weeks 
4 to 52) and at each post-randomization visit has been described in Section 6.4.4.1 (Table 2.1.2 
and Figures 2.1.2, 2.1.2.1, and 2.1.2.2 for the Japanese mITT Population). 
Similar analyses will be performed on Change from baseline in morning pre-dose trough for 
FVC, PEFR, and FEF25-75 over 52 weeks (Weeks 4 to 52), and at each post randomization visit 
measured for the Japanese mITT Populations (Tables and Figures 2.8.2, 2.8.8, and 2.8.14 for
FVC, PEFR, and FEF25-75).  
6.4.5.8
Rate of COPD Exacerbations 
COPD Exacerbations 
A COPD exacerbation will be defined as a change in the subject’s usual COPD symptoms that 
lasts 2 or more days, is beyond normal day-to-day variation, is acute in onset, and may warrant a 
change in regular medication. The change in symptoms must include at least one major COPD 
symptom and at least one other major (dyspnea, sputum volume, and sputum color) or minor 
symptom (cough, wheeze, sore throat, cold symptoms, and fever without other cause). 
Exacerbations will be considered moderate if they result in:  
 
•
Use of systemic corticosteroids and/or antibiotics for at least 3 days; a single depot injectable 
dose of corticosteroids will be considered equivalent to a 3-day course of systemic 
corticosteroids. 
Exacerbations will be considered severe if they result in:  
•
An inpatient COPD-related hospitalization (documentation stating that the subject was 
hospitalized for the COPD exacerbation or a record of the subject being admitted for 24

hours to an observation area, the emergency department, or other equivalent healthcare 
facility depending on the country and healthcare system). 
•
COPD-related death. 
Moderate-or-severe COPD exacerbations will be entered in the eCRF.  
Additionally, the investigator may identify certain events (recorded on the same CRF page) 
which don’t entirely meet the criteria above as exacerbations; the justifications supporting the 
investigator’s judgment will be recorded on a separate page on the eCRF. 
COPD exacerbations not meeting the criteria for moderate or severe COPD exacerbations will be 
considered to be mild COPD exacerbations. For more detail about moderate-or-severe, severe, 
and any-severity COPD exacerbation events (and their start and end dates) and how they are 
operationally defined, see the subsections titled “Duration of COPD Exacerbation”, “Moderate-
or-Severe Exacerbation and Severe Exacerbation: Operational Definitions:”, and “Exacerbation 
of any Severity: Operational Definition:”. 
Tipping Point Analyses for Rate of Moderate or Severe COPD Exacerbations  
Robustness of results to missing data will be explored using tipping point analyses (Ratitch 
2013). A brief overview of the approach is summarized in the table below. Details of the 
methods are similar to sensitivity analyses of FEV1 and AUC0-4 (found in Sections 6.4.4.4 and in 
the Details Appendix to this SAP), but with the negative binomial model for rate of moderate or 
severe COPD exacerbations described below.

compared adjusting for baseline post-bronchodilator percent predicted FEV1 and baseline 
eosinophil count as continuous covariates and baseline COPD exacerbation history (0, 1,

exacerbations will be considered separate events provided that there are more than 7 days 
between the recorded stop date of the earlier event and the start date of the later event. 
Time at risk of experiencing an exacerbation will be used as an offset variable in the 
model.  
x
For the efficacy estimand, the time at risk is defined as time of exposure to randomized 
treatment – not during or within 7 days after an exacerbation (of equal or greater severity)

– until the last dosing date. More precisely, this is the amount of time between the date of 
first dose of study medication and the date of premature discontinuation from study 
medication plus + 1 day or the date of completion of study medication minus the number 
of days while the subject was experiencing any exacerbation and minus the seven days 
subsequent to any exacerbation. Any days subsequent to the date of premature 
discontinuation from study medication + 1 day or the date of completion of study 
medication are not subtracted. For the treatment policy estimand, time at risk is defined 
as follow-up time (equivalently, the total exposure to randomized medication and post-
treatment follow-up for efficacy) – not during or within 7 days after an exacerbation (of 
equal or greater severity) – up to the last recorded date (of any assessment or contact) for 
the subject (including telephone contact) (Tables 2.13.1.1 and 2.13.4.1 for the efficacy 
estimand, and the treatment policy estimand, respectively). The per protocol estimand is 
not applicable for this endpoint.

Duration of COPD Exacerbation  
For moderate or severe exacerbations, the duration is defined by the length of prescribed 
treatment (using the eCRF COPD exacerbation page), whereas for mild exacerbations, the 
duration is defined by the length of symptoms.  
For moderate or severe COPD exacerbations, the start date will be defined as the start date of 
prescribed treatment with a systemic corticosteroid or systemic antibiotic and the stop date will 
be defined as the latter of the last day of prescribed treatment with a systemic corticosteroid or 
systemic antibiotic (if applicable). In order to ensure that the same event is not counted twice, 
consecutive or concurrent moderate or severe COPD exacerbations with equal to or fewer than 7 
days between the recorded stop date of the earlier event and start date of the later event will be 
considered the same event and assigned the maximum severity between the two. 
For mild COPD exacerbations, start date will be defined as the onset of worsened symptoms as 
recorded by the subject in the eDiary, and the stop date will be defined as the last day of 
worsened symptoms. In order to ensure that the same event is not counted twice, consecutive or 
concurrent mild COPD exacerbations with equal to or fewer than 7 days between the recorded 
stop date of the earlier event and start date of the later event will be considered the same event.  
In addition, in order to not double-count exacerbations, eDiary data from dates within 7 days 
prior to or after a moderate or severe exacerbation will not be counted as an additional mild 
COPD exacerbations. This implies that continuing worsened symptoms that meet the definition 
of a mild exacerbation would need to be present at least 2 days prior to the 7-day period 
immediately preceding the start date of a moderate or severe COPD exacerbation in order to be 
considered a separate event. Similarly, worsened symptoms would need to be present for at least 
2 days after the 7-day period immediately following a moderate or severe COPD exacerbation to 
be considered a separate event.  
Analyses of each severity of exacerbation will account for the time that subjects are at risk of 
having an exacerbation of that severity or greater. Time during or immediately following – i.e. 
within 7 days of – an exacerbation will not be considered as part of the time that the subject was 
at risk. However, time during or immediately following an exacerbation of lower severity will be 
included since, for example, a subject experiencing a mild exacerbation is still at risk of the event 
increasing in severity and becoming a moderate exacerbation. Moderate and severe COPD 
exacerbations occurring within 7 days of one another will be coalesced into a single COPD 
exacerbation event with the severity of “severe” (see details below).  
Moderate-or-Severe Exacerbation and Severe Exacerbation: Operational Definitions: 
x
Moderate exacerbations and severe exacerbations will be defined based on information 
from the COPD Exacerbation eCRF page. A time interval from a single COPD 
exacerbation eCRF page will be designated as being during an event of a moderate-or-

severe COPD exacerbation if for that interval, either antibiotics or oral corticosteroids 
were administered for the exacerbation. 
 
Call this time interval a “P-Interval”. The start date of the P-Interval is the earliest start date 
of the above, and the stop date will be defined as the last stop day of the above. If the subject 
was hospitalized due to the exacerbation or if the exacerbation led to a COPD-related death, 
then the severity of “severe” will be assigned to this P-interval; otherwise the severity of 
“moderate” will be assigned. The later of the stop date of the treatment with a systemic 
corticosteroid and the stop date of the treatment with an antibiotic will be the end date of the 
COPD exacerbation (i.e. the end of the P-Interval).  
An overarching interval of (any number of) such P-Intervals – including any P-Intervals with 
an end date not more than 7 days prior to the start date of some other P-Interval or with a 
start date not more than 7 days after the end date of some other P-Interval – and including the 
days in any gaps between them – will be called an “QMS-Interval”. This QMS-interval will 
represent the consolidated duration of several exacerbations recorded on different CRF 
pages. This QMS-Interval will be considered to be a single event of a moderate-or-severe 
COPD exacerbation. See Figure 2. 
x
A P-interval of severe COPD exacerbation is called a “severe” P-Interval. Any QMS 
interval that contains at least one “severe” P-Interval will also be called a “QS-Interval”. 
This QS-Interval will be considered to be a single event of a severe COPD exacerbation.

In summary, we combine CRF-based moderate-or-severe COPD exacerbation events if they are 
close enough together in time (Figure 2). We also combine severe COPD exacerbation events 
with other severe COPD exacerbation events or with moderate-or-severe COPD exacerbation 
events if they are close enough together in time (Figure 2) – thus forming a single severe COPD 
exacerbation event. We also combine mild-moderate-or-severe COPD exacerbations if they are 
close enough together in time; this coalescing is done first within-data-source (CRF [Figure 2] or 
diary [Figure 3]) and then between the two sources (Figure 4).

Time-at-Risk for COPD Exacerbations of Various Severities: Operational Definition 
x
During a time when a subject is not experiencing a severe COPD exacerbation (i.e. QS 
interval) – and is not in the seven days following a severe COPD exacerbation – a subject 
is considered to be at risk of having a severe exacerbation. During a time when a subject 
is not experiencing a moderate-or-severe COPD exacerbation (i.e. QMS interval) – and is 
not in the seven days following a moderate-or-severe COPD exacerbation – a subject is 
considered to be at risk of having a moderate-or-severe exacerbation. During a time when 
a subject is not experiencing an any-severity COPD exacerbation (i.e. QQ interval) – and 
is not in the seven days following an any-severity COPD exacerbation – a subject is 
considered to be at risk of having an any-severity exacerbation. 
Overarching coalesced intervals (i.e. events) of COPD exacerbation will be listed for severe 
exacerbations, moderate -to-severe exacerbations, and any-severity exacerbations (Listing
6.1.2.3). A severe COPD exacerbation event must be classified also as a moderate-or-severe 
event and also as an any-severity event. A moderate-or-severe COPD exacerbation event must be 
classified also as an any-severity event. 
PT010006:

Rate of COPD exacerbations of any severity will be analyzed in a manner similar to the 
rate of moderate or severe COPD exacerbations (Table 2.13.11.1 for the efficacy 
estimand). 
x
Rate of severe COPD exacerbations will be analyzed in a manner similar to the rate of 
moderate or severe COPD exacerbations (Table 2.13.12.1 for the efficacy estimand). 
PT010007:

Rate of COPD exacerbations of any severity will be analyzed in a manner similar to the 
rate of moderate or severe COPD exacerbations (Table 2.13.11.2 for the efficacy 
estimand with the Japanese mITT Population). 
x
Rate of severe COPD exacerbations will be analyzed in a manner similar to the rate of 
moderate or severe COPD exacerbations (Table 2.13.12.2 for the efficacy estimand with 
the Japanese mITT Population). 
The count of COPD exacerbations of any severity is the number of QQ-Intervals (for a subject) 
as defined previously. Time at risk of experiencing an exacerbation will be used as an offset 
variable in the model. Time during an exacerbation (of any severity) or in the 7 days following 
an exacerbation (of any severity) will not be included in the calculation of exposure (i.e. time at 
risk). Data related to COPD exacerbations of any severity are listed in Listings 6.1.2.1, 6.1.2.2, 
6.1.2.3, and 6.1.4. For moderate-or-severe COPD exacerbations that were identified apart from 
an eDiary alert, the symptom information is listed in Listing 6.1.2.2.

6.4.6
Time to Clinically Important Deterioration 
Time to CID will be analyzed for PT010006. 
Two definitions of CID will be used: 
x
CID: is  100 mL decrease (from baseline) in trough FEV1, or  4 points increase (from 
baseline) in SGRQ total score, or a TDI focal score of -1 point or less, or treatment-
emergent moderate-or-severe COPD exacerbation occurring up to Week 24. 
x
Sustained CID: is  100 mL decrease (from baseline) in trough FEV1, or  4 points 
increase (from baseline) in SGRQ total score, or a TDI focal score of -1 point or less, any 
of which is occurring on two consecutive analysis visits or for  50% of all available 
subsequent analysis visits, or a treatment emergent moderate-or-severe COPD 
exacerbation occurring up to Week 24 
Time to CID analysis will be performed for each CID definition using the Cox regression model. 
The model will include baseline post-bronchodilator percent predicted FEV1, baseline eosinophil 
count, baseline COPD exacerbation history (0, 1, >=2), country, and ICS use at Screening 
(yes/no). Time to a CID event will be based on the component event which occurs first. Subjects 
who do not have a CID event will be censored at the earliest day among the component 
censoring times. COPD exacerbations happening after Week 24 will not be counted as CID 
events. Estimated adjusted hazard ratios will be displayed along with associated 95% CI and p-
values (Tables 2.60.1, to 2.60.5). Time to CID will be displayed for each treatment group using a 
Kaplan-Meier curve (Figures 2.60.1 to 2.60.5). Time to CID will be analyzed for the efficacy 
estimand, the attributable estimand, the treatment policy estimand, and the per protocol estimand. 
The comparison of BFF MDI to Symbicort TBH will be for non-inferiority with the per protocol 
estimand rather than superiority and will use a margin of 1.1 for the upper bound of the two sided 
95% CI for the hazard ratio. 
For the analysis of the attributable estimand, missing data that have been reasonably attributed to 
tolerability or lack of efficacy will be imputed based on either the 5th or the 95th percentile (see 
below) of the reference arms’ distribution. The attributable estimand for time to CID will employ 
multiple by-visit imputation of pre-dose trough FEV1 and the SGRQ total score (at visits for 
which they are missing) (as described in Sections 6.4.4.1 and 6.4.5.3, respectively) and multiple 
imputation of time to first moderate-or-severe COPD exacerbation. A complete dataset for the 
COPD exacerbation count will be created analogously to that described in the analysis of Rate of 
Moderate or Severe Exacerbations in Section 6.4.5.8; however, the timing of imputed events is 
also needed. These will be obtained for each imputed event by randomly drawing a value from 
the uniform distribution over the interval that starts with time of treatment discontinuation + 1 
day (in study days) and ends at 24 weeks. The attributable estimand for time to CID will also 
employ multiple by-visit imputation of the TDI focal score in a manner similar to that for SGRQ. 
The application of the percentile penalty to the attributable estimand will be carried out for the 
four component variables simultaneously.

Analysis of Other Endpoints 
6.4.7.1
Percentage of Days with “No Rescue Ventolin HFA Use” Over the Treatment 
Period 
PT010006: 
As a supportive analysis, percentage of days with “no rescue Ventolin HFA use” over 24 weeks 
will be analyzed. A “day with no rescue use” is defined as any day where the subject reported 
zero puffs of rescue Ventolin HFA. The rescue Ventolin HFA usage diary data from days where 
rescue Ventolin HFA usage data is non-missing will be used to ascertain the days with “no 
rescue Ventolin HFA use”. The percentage of days with no rescue use will be calculated as 100 x 
(number of days no rescue Ventolin use over the entire treatment period / number of days with 
non-missing rescue Ventolin use over the entire treatment period). The percentage of days with 
“no rescue use” will be summarized by treatment and analyzed using ANCOVA with baseline 
average daily rescue Ventolin HFA use, percent reversibility to Ventolin HFA, baseline post-
bronchodilator percent predicted FEV1, baseline blood eosinophil count as continuous covariates 
and ICS use at Screening as a categorical covariate. Two-sided p-values and point estimates with 
2-sided 95% CIs will be produced for each treatment difference (Tables 2.15.1 for the efficacy 
estimand).  
For the efficacy estimand, the analyses of Percentage of Days with “No Rescue Ventolin HFA 
Use” will be restricted to the Rescue Ventolin User Population. 
PT010007: 
Percentage of days with “no rescue Ventolin HFA use” over 52 weeks (PT010007) will be 
summarized descriptively (Table 2.15.2 for the efficacy estimand with the Japanese mITT 
Population). 
6.4.7.2
Time to First COPD Exacerbation 
Time to First COPD Exacerbation will be analyzed for PT010006. 
Time to first COPD exacerbation of any severity is the time from first dose of study medication 
(or from randomization for any subjects randomized but not treated) to the time of onset of the 
first COPD exacerbation (mild, moderate, or severe). Time to first severe COPD exacerbation is 
the time from first dose of study medication (or from randomization for any subjects randomized 
but not treated) to the time of onset of the first COPD exacerbation (severe). Time to first 
moderate or severe COPD exacerbation is the time from first dose of study medication (or from 
randomization for any subjects randomized but not treated) to the time of onset of the first COPD 
exacerbation (moderate or severe).  
The time to first COPD exacerbation of any severity will be analyzed up through Week 24 using 
a Cox regression model. Treatment comparisons will be performed using the model, adjusting 
for baseline percent predicted FEV1 and baseline eosinophil count as continuous covariates and

baseline COPD exacerbation history (0, 1, 2), country, and ICS use at Screening (Yes/No) as 
categorical covariates. Estimated adjusted hazard ratios relative to the comparator for each 
treatment comparison will be displayed along with the associated Wald two-sided 95% CIs and 
p-values (Table 2.13.13 for the efficacy estimand).  
Time to first COPD exacerbation of any severity will be displayed graphically for each treatment 
using a Kaplan-Meier curve (Figure 2.13.13 for the efficacy estimand). Subjects who do not 
experience a COPD exacerbation over treatment period will be censored at the Week 24 visit. 
Subjects who withdraw from the study without experiencing a COPD exacerbation will be 
censored at the date of withdrawal or the last date of treatment, whichever is later. Time to first 
moderate or severe COPD exacerbation will be analyzed and displayed similarly to the time to 
first COPD exacerbation of any severity (Table and Figure 2.13.19 for the efficacy estimand and 
Listing 6.1.2.3). 
Time to first severe COPD exacerbation will be analyzed similarly to the analysis for time to first 
COPD exacerbation of any severity (Table 2.13.20 and Figure 2.13.19).  
6.4.7.3
Time to Treatment Failure 
Time to Treatment Failure will be analyzed for PT010006. 
Treatment failure is defined as a moderate or severe COPD exacerbation or premature 
discontinuation from treatment for any reason or death. Time to treatment failure will be 
displayed graphically for each treatment group using a Kaplan-Meier curve and analyzed using a 
log-rank test to compare the curves between the treatments (Figure 2.14.1). Subjects who do not 
experience a treatment failure will be censored at their Week 24 Visit. The time to treatment 
failure will be analyzed using the efficacy estimand. The model will include treatment, baseline 
post-bronchodilator percent predicted FEV1, baseline eosinophil count, baseline COPD 
exacerbation history (0, 1, >=2), country, and ICS use at Screening (yes/no). Estimated adjusted 
hazard ratios will be displayed along with associated 95% CI and p-values (Table 2.14.1). 
6.4.7.4
European Quality-of-Life-5 Dimension-5 Level Questionnaire 
Data from the EQ-5D-5L will be analyzed for PT010006. 
The data will be weighted to calculate an index score based upon subjects’ responses to the 5 
dimensions. The visual analogue scale (VAS) will be scored from 0 (worst imaginable health 
state) through 100 (best imaginable health state) to represent the subject’s self-report concerning 
how bad or how good their health was during that day. 
EQ-5D will be presented in three different ways:  
1. Presenting results from the EQ-5D-5L descriptive system as a health profile at baseline, at all 
visits, and at EoT (%, n) by domain  
2. Presenting results of the VAS as a measure of overall self-rated health status - baseline scores, 
scores at each visit, changes from baseline at each visit, and mean VAS score over the treatment 
period

3. Presenting results from the EQ-5D-5L index score (using UK value set) baseline, each visit, 
changes from baseline to each visit, and the mean index score over the treatment period.  
 
The percentage of subjects’ categorical responses to each of the 5-dimensions will be 
summarized (Table 2.16.1 for the efficacy estimand). Descriptive statistics for the index score 
(Table 2.16.7 for the efficacy estimand) and VAS (Table 2.16.13 for the efficacy estimand) will 
be presented by treatment group. VAS scores over 24 weeks may be analyzed using a similar 
RM model as is used for the TDI, but using baseline EQ-5D VAS score as a covariate instead of 
BDI (Table and Figure 2.16.7 for the index score and Table 2.16.13 for VAS for the efficacy 
estimand). EQ-5D data are listed in Listing 6.1.11. 
For calculations of index score, the method recommended by the national institute for health and 
care excellence (NICE) August 2017 will be applied. Cross-walk between EQ-5D-3L value set 
and EQ-5D-5L descriptive system have been developed by Van Hout et al 2012 (Van Hout et al. 
2012) and this cross-walk value set for EQ-5D-5L will be used to calculate the index score (Van 
Reenan 2015). Appendix 10 contains the SAS/SPSS codes for crosswalk between 5L and 3L for 
calculation of index score. 
 
No imputation will be made for missing data in either the EQ-5D-5L or VAS responses.  
 
The compliance of completing the EQ-5D-5L questionnaires is a critical issue in the QoL and 
health-state evaluation, and will be described by post-randomization visit, by displaying the 
number and percentage of subjects who were assessed (per subject, at least 1 question answered) 
at each visit (Table 2.16.19 for the efficacy estimand).
  
6.4.8
12-Hour Pulmonary Function Tests 
12-Hour PFTs will be analyzed for PT010006. 
FEV1 AUC0-12 will be measured in a subset of approximately 600 randomized subjects at Day 1 
(Visit 4) and Week 24 (Visit 10a). Area under the curve at Week 24 will be calculated using the 
trapezoidal rule, after first subtracting the baseline FEV1 value, and transformed into a weighted 
average by dividing by the time in hours from dosing of the last measurement included (typically 
12 hours). Spirometry data are listed in Listings 6.2, 6.3.9 for FEV1, 6.3.12 for FVC, 6.3.15 for 
PEFR, and 6.3.18 for FEF25-75 for the efficacy estimand). Participation in the 12-hr PFT Sub-
study is listed in Listing 9.7. 
At least one non-missing post-dose value is required for the calculation of AUC. Actual time 
from dosing will be used if available; otherwise scheduled time will be used. The differences 
between treatments in FEV1 AUC0-12 at Day 1 and Week 24 will be evaluated using an 
ANCOVA with baseline FEV1, baseline eosinophil count, and percent reversibility to Ventolin 
HFA as continuous covariates and treatment and ICS use at Screening as categorical covariates. 
Two-sided p-values and point estimates with two-sided 95% CIs will be produced for each

treatment difference (Table 2.17.1 to 2.17.4 for the efficacy, attributable, treatment policy, and 
per protocol estimands for FEV1 AUC0-12, and Table 2.17.7 and Figure 2.17.7 for FEV1 over 12 
hours post-dose for the efficacy estimand). The comparison of BFF MDI to Symbicort TBH will 
be for non-inferiority rather than superiority and will use a margin of -75 mL for the lower bound 
of the two sided 95% CI for the treatment difference; for that comparison, the analysis on the per 
protocol estimand will be the main analysis. As additional supportive analyses, FEV1 AUC0-4, 
FEV1 AUC0-6, and FEV1 AUC6-12 will be calculated and analyzed in a similar fashion as FEV1 
AUC0-12 (Tables 2.17.28 for AUC0-4, 2.17.31 for AUC0-6, and 2.17.34 for AUC6-12, for the efficacy 
estimand). Similar analyses (as for AUC0-4 and AUC0-12) will be performed for FVC, PEFR, and 
FEF25-75 (Tables 2.17.37 for FVC AUC0-4, 2.17.40 for FVC AUC0-12, 2.17.43 for PEFR AUC0-4,
2.17.46 for PEFR AUC0-12, 2.17.49 for FEF25-75 AUC0-4, 2.17.52 for FEF25-75 AUC0-12, for efficacy 
estimand). The baseline covariate will be endpoint-specific.
Treatments will be compared using change from baseline at each post-dose time point over 
12 hours at Week 24 (Visit 10a) for the following variables: FEV1, FVC, PEFR, and FEF25-75. 
The differences between treatments will be evaluated using an ANCOVA with baseline of the 
respective endpoint, baseline eosinophil count, and percent reversibility to Ventolin HFA as 
continuous covariates and treatment and ICS use at Screening as categorical covariates (Tables 
and Figure 2.17.7 and Listing 6.3.9 for FEV1, 2.17.13 and Listing 6.3.12 for FVC, 2.17.19 and
Listing 6.3.15 for PEFR, and 2.17.25 and Listing 6.3.18 for FEF25-75 for the efficacy estimand).
The 12-hour post-dose trough is defined as the average of the 11.5 and 12 hour post-dose values. 
In subjects missing either of these assessments, the value will be calculated from the single 
measurement. In subjects missing both values, this value will be missing. 
The attributable estimand (for the analysis of FEV1 AUC0-12) will be computed in a similar 
manner as the attributable estimand is computed for change from baseline in morning pre-dose 
trough FEV1 at Week 24 as described in Section 6.4.4.1.

(combined subgroups) analysis. Estimates for the treatment effect and for the treatment

differences will be displayed in the efficacy endpoint tables for each subgroup (Tables 6.1.1 to
6.11.40). 
 
For each subgroup analysis, a test for the treatment-by-subgroup interaction will be performed 
using the same model that was used for the overall (combined subgroups) analysis but with the 
addition of terms for subgroup and the treatment-by-subgroup interaction. A table will be 
provided with the p-value for the test of the treatment-by subgroup interaction (Table 6.13 for the 
efficacy estimand). Should any country/region effects be identified, shrinkage estimates may be 
generated in order to further understand the impact of these effects (Carroll and Fleming, 2013). 
Subgroup analyses of the trough FEV1 will be conducted in the baseline eosinophil count-high 
(150 cells per mm3) and the baseline eosinophil count-low (<150 cells per mm3) subgroups. It is 
acknowledged 150 cells per mm3 may not ultimately be the appropriate threshold for evaluation 
of treatment benefit. Thus, additional analyses will evaluate alternative thresholds, and the 
results from these analyses could then inform thresholds for future clinical studies. This 
exploration will include using additive mixed models that combine nonparametric regression for 
the relationship of eosinophil levels to trough FEV1 as well as potentially using subgroups 
defined by different cut points. 
6.4.9.1
China and Asia Subgroups 
The China subgroup is defined as all subjects enrolled in sites in China. The Asia subgroup is 
defined as all subjects enrolled in sites located in Japan and China. 
Corresponding ITT, mITT, RVU, PP and Safety analysis populations, as well as other relevant 
analysis sets, for the China and Asia subgroups are defined as described in Section 5.1 and 
restricted to the China/Asia subgroups. Populations described for primary analyses in Section 5.2 
are applied to China/Asia subgroups. 
6.4.9.2
Subgroup Analyses China and Asia 
To support registration in China, a separate Clinical Study Report will be written to present the 
study results in the China and Asia subgroups with the objective of demonstrating consistency 
with the overall Study PT010006 population. Select subject disposition, demographic and 
baseline characteristics, extent of exposure, prior and concomitant medications, efficacy, and 
safety analyses will be repeated for the China/Asia subgroups. Appendix 8 and Appendix 9 
contain the table of contents for Post-Text TFLs in the China and Asia subgroups, respectively. 
Analyses in the China and Asia subgroups will proceed as described in Section 6.4.9. All 
analyses based on the China and Asia subgroups will be considered exploratory. No adjustment 
for multiplicity will be made; thus the hierarchical testing detailed in Section 6.4.11 to control 
the Type I error will not be employed directly to the China and Asia subgroups.

6.4.10
Correlations
Pearson correlation coefficients will be generated between the primary and secondary continuous 
endpoints (from Japan/China Approach, EU/Canada Approach, US Approach). SGRQ total score 
will be used in place of the SQRQ responder. The mITT population will be used.  
Note that for morning trough FEV1, AUC0-4 FEV1, TDI, and change from baseline in SGRQ, the 
estimates over 24 weeks were obtained as LS means from MMRM analyses, and were not 
derived at the subject level. For the purpose of the correlation analysis, the endpoints over 24 
weeks will be represented by simple averages of available data over 24 weeks. 
The correlations will be organized in a matrix, with its upper triangle filled with pairwise 
Pearson correlation coefficients. All treatment groups will be pooled (Table 2.61.1 to 2.61.3). 
6.4.11
Control of Type I Error 
There are 3 separate plans for control of Type I error, corresponding to each of the 3 registration 
approaches for Japan/China, EU/Canada, and US. Each of the plans will test the primary 
endpoint using the efficacy estimand first for superiority comparisons, followed by the 
attributable estimand, which is considered a secondary endpoint. Additional secondary endpoints 
will only be tested using the efficacy estimand for Type I error control. Non-inferiority 
comparisons will be made using the per-protocol estimand. All secondary endpoints with the 
exception of time to onset are included in the Type I error control plans described below.  
6.4.11.1
Japan/China Approach: 
The comparisons of interest for the Japan/China approach are BGF MDI versus BFF MDI and 
BGF MDI versus GFF MDI, both for superiority, and BFF MDI versus Symbicort TBH for non-
inferiority. 
Strong control of the Type I error rate will be maintained at the 2-sided 0.05 level for the primary 
endpoint across key treatment comparisons using a sequential approach across comparisons, and 
then for the secondary measures, Type I error control will be maintained within comparison 
using a combination of sequential and simultaneous approaches as detailed below. Based on 
positive dependence of the test statistics (Sarkar, 2008; Sarkar and Chang 1997), simultaneous 
control of Type I error for the relevant secondary measures will be achieved using the Hochberg 
procedure (Hochberg, 1988).  
The following 3 between-treatment comparisons will be conducted, in the order stated, for 
morning pre-dose trough FEV1 over Weeks 12 to 24: BGF MDI versus BFF MDI, BGF MDI 
versus GFF MDI, using the efficacy estimand, and BFF MDI versus Symbicort TBH (non-
inferiority) using the per-protocol estimand. Each comparison will be made only if the preceding 
comparison in the sequence is statistically significant.  
If the comparisons for BGF MDI versus BFF MDI and BGF MDI versus GFF MDI are both 
statistically significant at a 2-sided alpha level of 0.05, testing will proceed to comparison of the 
respective attributable estimands in the same order. If the comparisons of the attributable 
estimands are also significant, then the secondary measures within each comparison will be

tested using the efficacy estimand. Type I error will be controlled at 0.05 within each comparison 
(BGF MDI versus BFF MDI, BGF MDI versus GFF MDI) for the remaining secondary 
endpoints through simultaneous testing under the Hochberg procedure with a 2-sided alpha of 
0.05. 
If non-inferiority is established for the comparison of trough FEV1 between BFF MDI and 
Symbicort TBH, then tests of the additional secondary measures for this comparison will be 
interpreted without any additional control of Type I error. Non-inferiority margins appear 
throughout the document in description and analyses of the endpoints as applicable.

All subsequent comparisons below will use only the efficacy estimand. 
If the comparison of FEV1 AUC0-4 between BGF MDI and BFF MDI using the attributable 
estimand above is statistically significant, testing will proceed to the secondary comparison of 
BGF MDI versus BFF MDI for change in morning pre-dose trough FEV1 using a 2-sided 0.05 
level test. If this test is also significant, testing will proceed to the remaining secondary 
endpoints. BGF MDI versus BFF MDI will be simultaneously compared among these secondary 
endpoints using the Hochberg procedure with a 2-sided alpha of 0.05.  
If the comparison of BGF MDI versus GFF MDI for change in morning pre-dose trough FEV1 
using the attributable estimand is statistically significant, testing will proceed to the remaining 
secondary endpoints for BGF MDI vs. GFF MDI using the efficacy estimand. BGF MDI versus 
GFF MDI will be simultaneously compared among the secondary endpoints using the Hochberg 
procedure with a 2-sided alpha of 0.05. 
If the comparison of FEV1 AUC0-4 for BGF MDI versus BFF MDI is statistically significant 
using the attributable estimand, testing will also proceed to a comparison of BGF MDI versus 
Symbicort TBH for of FEV1 AUC0-4 using the efficacy estimand. If statistically significant, the 
remaining secondary endpoints for BGF MDI versus Symbicort TBH will be simultaneously 
compared among the secondary endpoints using the Hochberg procedure with a 2-sided alpha of 
0.05. 
Finally, if the comparison of FEV1 AUC0-4 over 24 weeks for BGF MDI versus BFF MDI is 
statistically significant, testing will proceed to the non-inferiority comparisons of BFF MDI 
versus Symbicort TBH. If non-inferiority is established, tests of the additional secondary 
measures for this comparison will be interpreted without any additional control of Type I error. 
Non-inferiority margins appear throughout the document in description and analyses of the 
endpoints as applicable.

6.4.11.3
US Approach 
The comparisons of interest for the US approach are: BGF MDI versus GFF MDI and BGF MDI 
versus BFF MDI, both for superiority, and at Week 24 unless stated otherwise. Statistical 
significance for nominal comparisons will be at alpha=0.05. 
Strong control of the Type I error rate will be maintained at the 2-sided 0.05 level for the key 
comparisons using a sequential approach for the primary endpoints and then for the secondary 
measures Type I error control will be maintained within comparison using a combination of 
sequential and simultaneous approaches as detailed below. 
The following 4 comparisons will be conducted first, in the order they appear below: 
x
FEV1 AUC0-4 for BGF MDI versus BFF MDI using the efficacy estimand 
x
Trough FEV1 for BGF MDI versus GFF MDI using the efficacy estimand 
x
FEV1 AUC0-4 for BGF MDI versus BFF MDI using the attributable estimand 
x
Trough FEV1 for BGF MDI versus GFF MDI using the attributable estimand 
 
If the comparison of FEV1 AUC0-4 between BGF MDI versus BFF MDI using the attributable 
estimand is statistically significant, the remaining secondary endpoints for BGF MDI versus BFF 
MDI will be compared simultaneously using the efficacy estimand, and using the Hochberg 
procedure with a 2-sided alpha of 0.05. 
If the comparison of trough FEV1 AUC0-4 between BGF MDI versus GFF MDI for the 
attributable estimand is statistically significant, the secondary endpoints for BGF MDI versus 
GFF MDI will be simultaneously compared using the Hochberg procedure with a 2-sided alpha 
of 0.05.

Safety Analysis 
All safety analyses for PT010006 are based on the Safety Population. Most safety analyses for 
PT010007 employ the Japanese Safety Population. A few analyses for PT010007 employ the 
PT010007 Safety Population. Hypothesis testing will not be performed for any safety analyses. 
For PT010006, all AE data, clinically significant laboratory values, vital signs, and ECG values 
will be categorized according to their onset date into the following study periods: 
x
Events occurring during the Treatment Period are events with an onset date on or after 
the first date of dose and up to and including the date of completion of study treatment or 
the day after the date of premature discontinuation from study treatment. Events known 
to have occurred before the time of the first dose of study treatment are not included.  
x
Events occurring during the Post-treatment-discontinuation Follow-up are events with an 
onset date on [or after] the day after the dateof completion of study treatment or on or 
after the day after the day after (i.e. 2 days after) the date of premature discontinuation of 
study treatment. The exception is that deaths are still considered to be during the 
Treatment Period if any adverse event that led to that death is during the Treatment 
Period. 
 
Any AEs, clinically significant laboratory values, vital signs, and ECG values during the 
Treatment Period will be tabulated and listed. Beginning on the day after the date of 
discontinuation from or completion of study medication, any new clinically significant ECGs, 
laboratory values, and vital signs will not be included in the tabulation or the computation of 
incidence rates, but will still be listed. Any new AEs, SAEs, and deaths during the Post- 
treatment-discontinuation Follow-up will be tabulated and listed. Tabulations of the incidence of 
deaths, AEs by system organ class (SOC), and SAEs by SOC will be provided using information 
collected after treatment discontinuation (as alternative tables). 
6.5.1
Adverse Events 
The version of the Medical Dictionary for Regulatory Activities (MedDRA) that is current at the 
time of database lock will be used to code verbatim terms for AEs for final analysis of the data. 
A glossary of MedDRA preferred terms used for adverse events reported in the study along with 
the associated Investigator’s verbatim term will be provided in Listing 7.2. 
An adverse event is considered on-treatment (i.e. treatment-emergent) if an event occurs after the 
first dose of study medication in the study, or if the AE worsened during the study after the first 
dose of study medication in the study (intensity and/or severity changed to a worsened grade) 
and the event onset is on or before the date of discontinuation from or completion of study 
medication. An adverse event that begins on the same date as the first dose of study medication 
is treatment-emergent if the AE begins after the time of first dose or if the time of AE onset is 
unknown. Adverse events with onset after the date of premature discontinuation from study 
treatment plus one day or after the date of completion of study treatment will not be considered

treatment-emergent, but will be tabulated separately (Table 3.2.1.18) and listed in adverse event 
data listings (Listing 7.1). . Adverse events that occur between the time the subject signs the 
informed consent form (ICF) for the study and the time when that subject is randomized are to be 
recorded as medical history unless the event met the definition of an SAE. Additionally, if an AE 
has an onset date on treatment and has an outcome of death, that death will be considered on 
treatment even if the date of death is after the last date of treatment+1.  
 
The incidence of an AE will be defined as the number and percentage of subjects experiencing 
an event. Adverse events will be tabulated at the level of the MedDRA preferred term and the 
MedDRA SOC for the Safety Population and for the Japanese Safety Population. These will also 
be summarized by duration of exposure for the Japanese Safety Population for both Studies 
PT010006 and PT010007 (using the combined data from both studies). No hypothesis tests will 
be performed. 
An overview table will be prepared for the Safety Population, for the Japanese Safety Population, 
and for the PT010007 Safety Population with the incidences of subjects with at least one TEAE, 
at least one serious TEAE, at least one TEAE related to study treatment, at least one serious 
TEAE related to study treatment, at least one TEAE leading to premature discontinuation, at 
least one serious TEAE leading to premature discontinuation, and a report of death (Tables 3.1, 
3.1.13, and 3.1.14). This overview table will also be presented by duration of exposure for the 
Japanese Safety Population (Tables 3.1.15 to 3.1.18). 
The following will be done for events with irregular onset dates. All treatment-emergent adverse 
events (TEAEs) will be included in the data listings regardless of the completeness of the onset 
dates. Partial dates will be imputed in order to determine if an AE is treatment-emergent using 
the imputation rules in Appendix 1; however, imputed dates will not be provided in the data 
listings. 
All adverse events, whether treatment-emergent or not, will be included in the listings. Reported 
adverse events by SOC, preferred term, treatment, country, center, subject and onset day will be 
provided (Listing 7.1). Reported adverse events by treatment, country, center, subject, and onset 
date will be presented in Listing 7.3. SAE-specific report information will be listed in Listing 7.7. 
The listing of adverse events will provide the severity, maximum severity, relationship to study 
drug, action taken and outcome for each adverse event. Adverse events leading to permanent 
discontinuation of study treatment will be listed for the Safety Population and for the Japanese 
Safety Population (Table 3.6.1, Table 3.6.2). A listing of any reported deaths during the study 
(prior to randomization, during the Treatment Period, or during the Post- treatment-
discontinuation Follow-up) will be provided (Table 3.15.2.1); study treatment taken prior to the 
death and the number of days since the last dose of this study treatment at the time of the death 
will be included in the listing.  
Summary tabulations of the following will be prepared for all subjects in the Safety Population, 
for each treatment, for each primary SOC, and for each preferred term within an SOC:

12. A summary tabulation will also be prepared for the incidence of TEAEs occurring in 
at least 2% of subjects in any treatment (Tables 3.2.2.1, 3.2.2.2 sorted by descending 
frequency of events in a preferred term).
13. In addition, to control for possible differences in exposure between the treatments, the 
following AE and SAE summaries will be presented with the frequency and rate of 
occurrence (total number of events per 1000 person-years of exposure) by treatment, 
primary SOC, and preferred term: 
a) Frequency and rate of AEs (Tables 3.3.1, 3.3.2) 
b) Frequency and rate of SAEs (Tables 3.8.3.1, 3.8.3.2) 
c) Frequency and rate of neoplasms (Tables 3.10.3.1 and 3.10.3.2 – All Cancer, 
3.10.4.1 and 3.10.4.2 - Excluding Non-Melanoma Skin Cancer). 
 
Safety summaries will be performed for AEs (overall summary of AEs and incidence of AEs by 
MedDRA SOC and preferred term in Tables 7.1.1 to 7.2.1.17f), SAEs (Tables 7.3.1.2 to

In addition to AE, SAE, and AEs of special interest summaries for the Japan subgroup described 
above, treatment-related AEs and AEs leading to discontinuation will also be summarized for the 
Japan subgroup (Tables 7.4 to 7.6) for PT010006.

Adverse Events of Special Interest 
AESIs have been defined based on known effects of s LAMAs, LABAs, and ICS. These include 
but are not limited to cardiovascular effects, ocular disorders, urinary retention, gastrointestinal 
disorders, and anticholinergic effects for LAMAs; cardiovascular, tremor effects, hyperglycemia, 
and hypokalemia for LABAs; and local (e.g., candidiasis and voice effects) and systemic (e.g., 
bone and skin effects, diabetes control, ocular and taste effects, adrenal suppression) steroid class 
effects and lung infection for ICS.  
SMQs will be utilized when possible, and a selection of high-level group terms (HLGTs), high-
level terms (HLTs), and preferred terms (PTs) will be utilized to represent other situations. The

The incidence of adverse Events in MedDRA SMQs/Groupings of Interest by Term will be 
tabulated for the Safety Population, and the Japanese Safety Population (Tables 3.2.3.1 and 
3.2.3.2), as well as for the China, Asia, and Japan Subgroups of the Safety Population (Tables
7.7.1 to 7.7.3). 
6.5.1.2
MACE Events Determined by Clinical Endpoint Committee 
The clinical endpoint committee (CEC) will review and adjudicate serious cardio- and 
cerebrovascular (CCV) events as MACE. MACE events are defined as the following: 
 
• Cardiovascular death 
 
• Non-fatal myocardial infarction (MI) 
 
• Non-fatal stroke 
 
The CEC will review and assess these non-fatal serious CCV events and all deaths as to whether 
or not they fulfill criteria (based on CEC working practices) for MACE. 
MACE events will be summarized by adjudicated CRF category and treatment group (Tables
3.13.1.1, 3.13.1.2). The assessment of MACE events will include the rate of confirmed MACE 
events (Tables 3.13.2.1, 3.13.2.2). Adjudicated MACE events will be listed in Listing 7.4. 
The incidence of subjects with adjudicated MACE AEs by category will be summarized in Table
3.13.3.1 and Table 3.13.3.2. 
6.5.1.3
Pneumonia Events Determined by Adjudication Committees 
All AEs/SAEs with preferred terms that could relate to pneumonia will be adjudicated to provide 
a more complete assessment of all physician-reported pneumonias. The incidence of confirmed 
pneumonia events will be tabulated (Tables 3.13.3.1, 3.13.3.2). The assessment of pneumonia 
events will include the rate of confirmed pneumonia events (Tables 3.14.2.1, 3.14.2.2). 
Adjudicated pneumonia events will be listed in Listing 7.4. 
 
In order to account for specific patient risk factors, data permitting, time to first pneumonia will 
be compared between treatments using Cox proportional hazards (Tables 3.14.3.1, 3.14.3.2). 
Specific patient risk factors (baseline FEV1, age, and medical history of pneumonia in the last 5 
years [Yes or No]) will be evaluated for inclusion. 
The incidence of subjects with adjudicated pneumonia AEs by category will be summarized in 
Table 3.13.3.1 and Table 3.13.3.2. 
6.5.1.4
Cause of Death Determined by Adjudication Committees 
Causes of death will be listed by subject and summarized by treatment for (1) all-cause mortality, 
(2) mortality of probable cardiovascular cause, (3) mortality of probable respiratory cause and

(4) mortality of probable other causes using the Safety Population based on (A) cases reported 
during the active Treatment Period and (B) cases reported during the active Treatment Period 
plus the Post-treatment-discontinuation Follow-up (Tables 3.15.2.1 and 3.15.2.2). The incidence 
of subjects with a death event will be tabulated by adjudicated CRF category and treatment 
during the Treatment Period (Tables 3.15.1.1, 3.15.1.2) and during the Post-treatment-
discontinuation Follow-up (Tables 3.15.1.3 and 3.15.1.4). To control for possible differences in 
exposure between treatments, the death will be summarized with frequency and rate of 
occurrence (total number of events per 1000 person-years of exposure) by treatment, primary 
SOC, and preferred term (Tables 3.15.3.1, 3.15.3.2). Adjudicated death events will be listed in

A Clinically Significant Laboratory Abnormality as identified by the investigator after the 
start of study treatment will be recorded as an Adverse Event and tabulated as an AE in the AE 
analysis. Abnormalities occurring prior to the start of treatment will be noted in medical history 
and presented in a data listing. Per protocol, the criteria for a "clinically significant" laboratory 
abnormality are: 
a.
A laboratory abnormality that leads to a dose-limiting toxicity (e.g., an abnormality that 
results in study drug dose reduction, suspension or discontinuation) 
b. A laboratory abnormality that results in any therapeutic intervention (i.e., concomitant 
medication or therapy) 
c.
Other laboratory abnormality judged by the Investigator to be of any particular clinical 
concern (e.g., significant fall in hemoglobin not requiring transfusion) 
All laboratory data will be stored in the database with the units in which they were originally 
reported. Laboratory data not reported in International System of Units (SI units; Système 
International d’Unités) will be converted to SI units before data analysis. 
Individual clinical laboratory variables for hematology and clinical chemistry and kidney 
function, including creatinine clearance, will be provided in listings (Listing 8.1 for hematology, 
Listing 8.2 for blood chemistry and kidney function, Listing 8.3 for urinalysis, and Listing 4.6 for 
pregnancy test results at screening and after the start of treatment). Data will be listed in SI units 
where available. Comments for laboratory testing will be listed (Listing 8.4). For listings, 
laboratory values will be flagged as Low or High based on the reference ranges provided by the 
central laboratory, LabCorp Laboratories (Appendix 4). 
The baseline measurement for a laboratory parameter will be the last available measurement 
prior to the start of dosing.

The laboratory-value windows will be applied only for calcium, chloride, glucose, potassium, 
and sodium (i.e. the laboratory parameters that are sometimes assessed post-dose) and these 
windows will be applied only at the following visits: Visit 4 (Day 1), Visit 5 (Week 4), and Visit

10a (Week 24). For other laboratory parameters and other visits, windows will not be applied. 
The rationale is that for other laboratory parameters and other visits, post-dose assessments are 
not to be assessed. 
If there are multiple laboratory values for the same parameter at pre-dose of a visit or within the 
same post-dose study time window (if applicable) at a visit, the last value will be chosen for 
analysis.  
Summary statistics (n, mean, median, standard deviation, minimum, and maximum) for the 
baseline assessment and for the pre-dose value and change from baseline at each post-baseline 
visit and end of treatment for scheduled lab assessments of continuous laboratory variables 
including serum potassium and glucose will be tabulated. “End of Treatment” is defined as the 
last non-missing assessment during the treatment period. Data from unscheduled visits will not 
be used for the by-visit summaries but both scheduled-visit values and unscheduled-visit values 
are candidates for the end-of-treatment summary. Data from both scheduled and unscheduled 
visits will be listed. The summaries will be provided by treatment (Tables 3.16.1.1 through 
3.16.4.2, for hematology, blood chemistry, kidney function, and urinalysis, respectively). 
Data from unscheduled visits will not be used for the by-visit summaries but both scheduled-visit 
data and unscheduled-visit data are candidates for clinically significant values, for the end-of-
treatment summary, and for shift tables. Shift tables will be produced using the categories 
defined by the Common Terminology Criteria for Adverse Events (CTCAE) Version 4.03 grades 
for the Safety Population (Tables 3.16.5.1, 3.16.6.1, and Table 3.16.7.1) for hematology, 
chemistry, kidney function and urinalysis, respectively) and the Japanese Safety Population 
(Tables 3.16.5.2, Table 3.16.6.2, Table 3.16.7.2 and Table 3.16.8.2 for hematology, chemistry, 
kidney function and urinalysis, respectively). For these shift tables, for each treatment, the 
subject’s pre-dose grade will be cross-tabulated by the subject’s maximum post-baseline grade 
during the treatment; also, the subject’s maximum post-baseline grade during treatment will be 
tabulated for all baseline grades combined. Percentages of subjects in each maximum post-
baseline grade for a treatment will be calculated for each pre-dose grade for the treatment and 
also for all baseline grades combined. Laboratory abnormal values on-treatment will be flagged 
as High or Low values based on laboratory reference ranges provided by LabCorp Laboratories 
(found in Appendix 4) as per Pearl, Inc. These flags along with the reference ranges will be 
provided in the laboratory data listings. 
Potentially Clinically Significant Laboratory Values Above/Below a Clinically Relevant 
Threshold on-treatment, based on CTCAE 4.03 and other criteria, will be identified based on the 
following thresholds:

Clinically significant laboratory values will be tabulated for the Safety Population (Table 3.16.9). 
Since a reduction in potassium and an increase in blood glucose are known class effects of 
beta-agonists, all potassium or glucose assessments for subjects who experienced newly 
occurring or worsening potentially clinically significant values after start of the study treatment 
will be provided in separate listings (Tables 3.16.10.1, 3.16.10.2, 3.16.11.1, and 3.16.11.2). For 
all laboratory parameters other than glucose and potassium noted in Table 8, all laboratory data 
for the parameter identified as potentially clinically significant for a subject will be listed (Table

Vital Signs 
Changes from Baseline in on-treatment supine or seated systolic blood pressure, supine or 
seated diastolic blood pressure, and heart rate will be evaluated, where baseline is defined as the 
mean of all available pre-dose measurements taken prior to the start of dosing at the 
Randomization Visit (Visit 4). If there are no Visit 4 pre-dose values, the baseline will be defined

as the mean of pre-bronchodilator values at Visit 2 and Visit 3. No Hypothesis testing will be 
performed. 
A Clinically Significant Abnormality in vital signs identified by the investigator will be 
recorded as an Adverse Event if it occurs after the start of treatment. These adverse events will 
be included in the AE summaries; abnormalities prior to the start of treatment will be noted in 
medical history and listed. 
Potentially clinically significant changes in systolic and diastolic blood pressure will be 
defined based on the following criteria provided by Pearl, Inc.:

Vital sign measurements (Heart rate, systolic blood pressure, diastolic blood pressure and body 
temperature, weight, height) during the study will be displayed in a vital signs listing 
(Listing 9.1). 
A summary of baseline weight, height, and BMI will be presented by treatment (Tables 1.4.1.1, 
1.4.3.1, 1.4.4.1 and 1.4.5.1 for the mITT, PP, and Safety Populations, and all subjects not 
randomized respectively). The ITT Population does not need to be summarized because it is the 
same as the mITT Population at baseline. The Safety Population may not be needed either. 
Summary statistics (n, mean, median, standard deviation and range) of the absolute value and 
change from baseline for systolic blood pressure, diastolic blood pressure, and heart rate, will be 
tabulated by treatment, visit, and time point. Baseline will be defined as the mean of the values 
prior to dosing at Visit 4 (Day 1). These summaries (Table 3.17.1.1, Table 3.17.1.2) will be

prepared for baseline and each scheduled post-baseline nominal time point at each scheduled 
post-baseline visit and end of treatment. “End of Treatment” will be summarized for each 
scheduled post-baseline time point (pre-dose 1 hr, and post-dose 30 minutes and 2 hour). “End of 
Treatment” for each of these assessment points is defined as the last non-missing on-treatment 
assessment available for the time point. Data from unscheduled visits will not be used for the by-
visit summaries, but both scheduled-visit data and unscheduled-visit data are candidates for the 
end-of-treatment summary. Data from both scheduled and unscheduled visits will be listed. Time 
windows will be derived for each post-baseline visit using the time intervals for the study time 
windows detailed in Table 13. No hypothesis tests will be performed.

If there are multiple vital sign values for the same parameter at pre-dose assessments after Visit 4 
or within the same post-dose study time window at a visit, the last value will be chosen for 
analysis. 
Data from unscheduled visits will not be used for the by-visit summaries but both scheduled-visit 
data and unscheduled-visit data are candidates for clinically significant values and for the end-of-
treatment summary. 
The percentage of subjects with potentially clinically significant values for vital signs at any time 
post-dose at a visit will be summarized by treatment based on the criteria in Table 11 and Table 
12 (Table 3.17.2.1- Safety Population, Table 3.17.2.2- Japanese Safety Population).All vital sign 
assessments for subjects with potentially clinically significant values will be listed (Tables

measurements taken prior to the start of treatment at the randomization visit (Visit 4). If there are 
no Visit 4 pre-dose values, the baseline will be defined as the mean of the pre-bronchodilator 
values at Visit 2 and Visit 3. The QTcF (Fridericia Corrected QT) is defined as [QT/(RR1/3)]. 
Heart rate (bpm) is estimated as 60,000/RR, where RR is in units of ms. These assessments will 
be tabulated for each treatment and assessment time.

A Clinically Significant Abnormality for a 12-Lead ECG measurement identified by the 
investigator as a clinically significant abnormality will be recorded as an Adverse Event if it 
occurred after the start of study treatment. These adverse events will be included in the AE 
summaries.
All 12-Lead ECG measurements for the Safety Population will be listed (Listing 9.2). Summary 
statistics (mean, median, standard deviation and range) for raw values and change from baseline 
values in Heart Rate, PR Interval, QRS Axis, QRS Interval, QT Interval and QTcF interval will 
be calculated, where baseline is defined as the mean of the pre-dose measurements taken prior to 
the start of treatment at Visit 4 (Day 1). These assessments will be tabulated for each treatment 
and each scheduled nominal time point (derived using the time intervals for the study time 
windows detailed below in Table 14) at each visit and at end of treatment (Table 3.18.1, Table 
3.18.2). “End of Treatment” will be summarized for each scheduled post-baseline time point 
(pre-dose 1 hour, post-dose 30 minutes, and post-dose 2 hours). End of Treatment for each of 
these assessment points is defined as the last non-missing on-treatment assessment available for 
the time point. Data from unscheduled visits will not be used for the by-visit summaries but both 
scheduled-visit data and unscheduled-visit data are candidates for the end-of-treatment summary. 
Data from both scheduled and unscheduled visits will be listed. Mean pre-dose change from 
baseline for heart rate and QTcF will be plotted across post-baseline visits by treatment (Figure
3.18.1a and Figure 3.18.1e). ECG data from subjects with pacemakers will not be included in 
analyses, but will be listed.

Analyses will be performed using the mITT Population. 
Descriptive statistics (n, mean, standard deviation, median, minimum and maximum) will be 
provided by actual treatment received for the number of days missed from work, the number of 
days that family members of subjects missed from work per year overall during the study (Table
3.20.1 and Listing 9.4). 
Also, descriptive statistics will be provided by actual treatment received and relationship to 
COPD (related, not-related, and total) overall during the entire Treatment Period for the 
following variables: the number of telephone calls to health-care providers, the number of visits 
to health-care providers, the number of ER visits, the number of number of times ambulance 
transport was required, the number of subject hospitalizations, the number of days in the 
hospital, the number of days in the ICU, and the number of days in the CCU (Table 3.20.2 and 
Listings 9.4 and 9.5).

Pharmacokinetic Analysis 
Blood samples for PK assessments will be taken prior to administration of study drug at Week 24 
and at 2, 5, and 20 minutes, and at 1, 2, 4, 8, 10, and 12 hours post-dose. Actual sampling time 
points relative to dosing will be used for PK assessments and analysis where available. If the 
actual sampling time is unknown, the scheduled protocol time may be used for the calculation of 
derived PK parameters. 
The concentration-time data reported by the bioanalytical laboratory will be evaluated for 
inclusion in the PK analysis dataset. 
The PK analysis will be performed for subjects in the PK Population. 
PK parameters will be estimated by non-compartmental analysis (NCA) using the software 
Phoenix® WinNonlin® (Pharsight Corporation, US). From the plasma budesonide, 
glycopyrronium and formoterol concentration-time data, the following PK parameters will be 
estimated for each subject where possible:

AUC0-12 
The area under the plasma concentration-time curve from time 0 to 12 hours 
post dose 
Cmax 
The maximum observed plasma concentration, expressed in concentration 
units 
tmax 
The time to reach Cmax, expressed in hours 
Ȝz
The terminal elimination rate constant, calculated from the slope of the 
terminal portion of the ln(drug concentration) versus time curve 
t1/2 
The apparent terminal elimination half-life, expressed in hours, calculated as 
ln2/ Ȝz 
Cmin 
The minimum observed plasma concentration, expressed in concentration 
units 
Cavg 
Average concentration during a dosing interval 
Fluctuation 
Degree of fluctuation [(Cmax-Cmin)/Cavg]  
Swing 
[(Cmax-Cmin)/Cmin] 
 
AUC0-12 will be calculated using the linear-log trapezoidal method. 
The PK parameters Cmax, Cmin and time to Cmax (tmax) will be obtained from the observed values. 
A 12-hour post-dose sampling schedule may not permit adequate estimation of Ȝz considering the 
known PK of the products. However, Ȝz will be estimated for each subject where feasible by 
linear regression analysis, calculated from the slope of the terminal portion of the ln(drug 
concentration) versus time curve. Selection of data points to include in the estimation of Ȝz for 
each subject for each treatment for each analyte will be based on the following criteria: 
x
All samples used should preferably fall in the log-linear elimination phase. 
x
At least 3 samples above the lower limit of quantification (LLQ) should be used in the 
estimation. 
x
Cmax must not be used in the estimation. 
 
In order for the selection to take place the adjusted r2 value reported in Phoenix® WinNonlin® 
must be above 0.7. 
Fluctuation, swing and t1/2 will be calculated using the formulas listed above. 
For the purposes of parameter estimation, plasma concentration values below the LLQ will be set 
to missing in the NCA. Missing values (e.g., no blood sample collected, no value obtained at 
analysis) will be treated as missing and excluded from the NCA. If there are 2 consecutive 
missing concentration values, the estimation of PK parameters will be evaluated on a case-by-
case basis. 
All concentration-time data reported by the bioanalytical laboratory, for each analyte, for each 
treatment, will be listed for subjects participating in the PK sub-study. Actual sample collection 
times will be detailed in the listing along with the scheduled nominal sample collection times. In

addition, all calculated PK parameters for each treatment for each analyte will be listed for 
subjects participating in the PK sub-study. 
Descriptive statistics for plasma concentrations of budesonide, formoterol, and glycopyrronium, 
by treatment, visit and time point will be summarized. Descriptive statistics will include the 
number of observations (n), mean (CV%), SD, standard error (SE), median, minimum (min), 
maximum (max), geometric mean, and geometric coefficient of variation (Tables 4.1 – 4.3). 
Descriptive statistics for PK parameters of budesonide, glycopyrronium, and formoterol, will be 
summarized by treatment and visit. Descriptive statistics will include the number of observations 
(n), mean (CV %), SD, median, minimum, maximum, geometric mean, and geometric 
coefficient of variation. For the PK parameter tmax, only the number of observations (n), mean, 
median, minimum (min), and maximum (max) will be presented (Tables 4.4-4.6). 
The plasma concentration-time profiles for individual and mean plasma concentrations of 
budesonide, formoterol, and glycopyrronium, will be presented for each treatment on the 
linear/linear scale and on the linear/log-linear scale. Mean and individual plots will be separate 
for each analyte. Nominal sampling time points relative to dosing will be used for all mean plots. 
Actual sampling time points will be used for all individual plots (Figures 4.1.1 through 4.6.2). 
Non-compartmental parameter estimates for budesonide, formoterol, and glycopyrronium  
AUC0-12 and Cmax will be natural-log transformed and analyzed using mixed effect models 
(Tables and Figures 4.7 – 4.9). 
The relative bioavailability of budesonide, formoterol, and glycopyrronium delivered via BGF 
MDI to delivery via GFF MDI, BFF MDI, or Symbicort TBH will be evaluated and summarized. 
Separate analysis of variance (ANOVA) models with fixed effects for treatment, will be fit for 
each analyte (Tables 4.7 – 4.9).

HPA Axis Analysis 
Twenty-four-hour SC levels will be obtained in a subset of PK sub-study subjects over 24 hours 
between Visits 3 and 4 prior to dosing at Randomization and Visit 10a (Week 24). 
Cortisol sampling will occur 30 minutes pre-dose, and 1, 2, 4, 8, 10, 12, 14, 16, 20, 22, and 24 
hours post-dose. All SC concentrations reported will be listed. 
The data reported by the bioanalytical laboratory will be evaluated for inclusion in the HPA Axis 
analysis dataset. 
The HPA Axis analysis will be performed for subjects in the HPA Axis Population. 
The following parameters will be estimated for each subject where possible:

0-24 hour weighted mean SC concentration

The 24-hour SC weighted mean concentration (AUC/t) will be obtained by dividing the AUC by 
the sample collection time interval within 24 hours; t is the difference in hours between last non-
missing time minus first non-missing time included in the AUC. The AUC will be calculated 
using the trapezoidal rule from the first non-missing time point to the last non-missing time 
point.  
Baseline is defined as the weighted mean 0-24 h from Day -1/1. If only one time point is 
available at either baseline or at Week 24, time-weighted average will use the single 
concentration value at that time point; in this case, baseline time-weighted average is just the 
single concentration value collected at baseline. 
Concentrations below the assay’s LLQ will be imputed with a value of LLQ/2 when deriving the 
weighted mean and AUC. If an observation is missing between 2 non-missing observations, the 
AUC will be calculated using the reported values at the adjacent time points.  
The primary analysis will be performed on the log-transformed ratio from baseline of the 
weighted mean SC for subjects in the HPA Axis Population. An ANCOVA model with baseline 
(log-transformed) value, gender, age, and treatment group as covariates will be used to draw 
comparisons between BGF MDI versus GFF MDI, BFF MDI versus GFF MDI, and Symbicort 
TBH versus GFF MDI. Estimated ratios and their 90% confidence intervals will be presented 
(Table 5.1).  
SC concentration values will be listed (Listing 11.1). Baseline and Week 24 weighted mean SC 
concentration will be listed for each subject (Listing 11.2). 
The ratio from baseline to Week 24 (Visit 10a) in the 0-24 hour weighted mean SC concentration 
at will be summarized by treatment group (Table 5.1).  
Descriptive statistics (n, mean, SD, median, minimum, maximum, geometric mean, and 
geometric coefficient of variation) for SC concentration by time point (for both Screening and 
Week 24) will be tabulated (Table 5.2). SC concentration profiles over 24 hours will be 
graphically presented by treatment group using box plots over time, at baseline and at Week 24 
(Figures 5.2.1 – 5.2.4).  
The percentage of subjects observing an at least 30% increase from baseline in 0- to 24-hour 
weighted mean SC concentration will be summarized by treatment group. The percentage of 
subjects observing an at least 30% decrease from baseline in 0- to 24-hour weighted mean SC 
concentration will also be summarized by treatment group. 
6.5.8
Physical Examination 
Any physical examination abnormality reported after the start of treatment for a subject is to be 
reported as an adverse event. Thus, these will be included in listings of adverse events and 
summarized in adverse event summaries. Abnormalities seen at the Screening physical 
examinations will be recorded as Medical History and listed.
