Description of Change
Rationale
1
Synopsis; Former Section 3.4: Exploratory 
Endpoints (Evaluated on Treatment Day 
8); Previous Section 7.1.6: Biomarkers; 
Section 8.3: Visit 3 (Randomization/Day 
1); Section 8.4: Visit 4 (Day 8); Section 
8.6: Visit 6 (Day 8); Section 9.2.1: 
Efficacy Endpoints, Former Section 9.2.2: 
Exploratory Endpoints (Evaluated on 
Treatment Day 8)
Deleted biomarker endpoints, any 
reference to biomarker endpoints and 
exploratory endpoints
Current biomarker endpoints considered 
to not add value to the study as 
biomarkers are not expected to show a 
difference between GFF MDI and 
Placebo MDI.
2
Synopsis
Corrected that baseline for 
plethysmography endpoints will be defined 
as the pre-dose value at Visit 2 and not the 
-30 min value at Visit 2.
Corrected to align with Section 7.1.3: 
Plethysmography, which indicates that 
at Visit 2, pre-bronchodilator 
plethysmography assessments will be 
conducted. No -30 min assessment will 
be conducted at Visit 2.
3
Synopsis, Primary Efficacy Endpoint; 
Section 3.1: Primary Efficacy Endpoint; 
Section 9.2.1.1: Primary Efficacy Endpoint
Revised that RVEDVi endpoint will be 
measured 2-3 hours post-dose instead of 2 
hours post-dose
Changed to allow correct sequence in 
timing for the MRI 
4
Synopsis, Secondary Efficacy Endpoints 
(Measured using MRI at 2 hours post-dose 
on Day 8); Section 3.2: Secondary Efficacy 
Endpoints (Measured using MRI at 2 hours 
post-dose on Day 8); Section 9.2.1.2: 
Secondary Efficacy Endpoints (Measured 
using MRI at 2 hours post-dose on Day 8) 
Changed to allow site flexibility in 
timing for the MRI assessments
Added to clarify that the PVR 
measurement is measured at a different 
time point than the timeframe the title 
indicates secondary endpoints will be 
measured.

Revised that the MRI endpoints will be 
measured 2-3 hours post-dose instead of 2 
hours post-dose on Day 8
Indicated that the PVR will be measured at 
30 minutes and 60 minutes post-dose
5
Synopsis, Other Efficacy Endpoints 
(Measured at 2 hours post-dose on Day 8 
unless otherwise noted); Section 3.3: Other 
Efficacy Endpoints (Measured at 2 hours 
post-dose on Day 8 unless otherwise 
noted); Section 9.2.1.3: Other Efficacy 
Endpoints (Measured at 2 hours post-dose 
on Day 8 unless otherwise noted)
Deleted “(Measured at 2 hours post-dose 
on Day 8 unless otherwise noted)” 
Revised that the plethysmography will be 
measured 1-2 hours post-dose instead of 2 
hours post-dose on Day 8 and the ICG 
assessments will occur 30 and 60 minutes 
post-dose instead of 2 hours on Day 8; 
Revised that MRI assessments will occur at 
2-3 hours post-dose on Day 8 instead of 2 
hours post-dose and that post-dose FEV1,
IC, and FVC will be measured at 1 hour 
post-dose on Day 8 instead of 2 hours post-
dose
Deleted under ICG assessments (Under 
second bullet) that the PVR will be 
measured at morning pre-dose trough and 
each post-dose time point (first sub-bullet);
Deleted PVR on Day 1 (second sub-bullet)
and Cardiac output on Day 1 (third sub-
bullet) as endpoints. This leaves only one 
endpoint under “other efficacy endpoints” 
for ICG endpoints.
Deleted timing as each set of 
assessments has been changed to a 
different time post-dose
Changed timings to allow site flexibility 
in timing for the plethysmography, ICG,   
MRI, and spirometry assessments
Deleted “Morning pre-dose trough for 
PVR” as an other efficacy endpoint and 
put as a secondary endpoint as post-dose 
PVR measurements are also secondary 
endpoints; Deleted “and each post-dose 
time point for PVR” as an other efficacy 
endpoint as this is already covered under 
the secondary endpoint of “ Pulmonary 
Vascular Resistance (PVR) by ICG”; 
Deleted PVR on Day 1 and Cardiac 
output on Day 1 as endpoints as there 
are no post-dose assessments on Day 1

qualify for study enrollment. 
Corrected to reflect actual criterion for 
spirometry at Visit 1.
10
Section 4.1: Overall Study Design and 
Plan; Section 5.4.1: Prohibited COPD 
Medications and Required Washout Prior 
to Visit 2

Corrected to indicate correct dosing 
regimen for Ventolin HFA.
11
Section 4.1: Overall Study Design and Plan 
(General Considerations for Treatment 
Visits 3 through Visit 6 (in-clinic): 
Deleted wording in bullet #7 that subjects 
must return to the clinic “but no later than 
10:00 AM” and changed that in-clinic 
dosing time is before “approximately 11:00 
AM”
To allow the subjects more flexibility 
with visit scheduling and to allow the 
site more flexibility with in-clinic dosing 
time to ensure all pre-dose assessments 
can be performed in a timely manner.

16
Section 7: Study Procedures
Indicated that assessments should be 
performed at the same time for a given 
subject across each treatment period. 
Clarified order of pre-dose assessments at 
Visit 3 and Visit 5 and order of pre-and 
post-dose assessments at Visit 4 and Visit 
6.
To ensure assessments are performed at 
a consistent time pre-and post-dose to 
avoid variability in response    
Based on revised timing for some 
assessments, the order was changed to 
align with these timings.
17
Section 7.1.1: Pulmonary Function Tests 
(Spirometry) 
Under the Note, added that spirometry will 
be conducted at Visit 1.
Revised timing of post-dose spirometry 
assessment from 2 hours to 1 hour at Visit 
4 and Visit 6.

and Visit 6 from 2 hours to 1 hour.
Revised timing to allow for site 
flexibility to ensure assessments are 
conducted in a timely manner
20
Section 7.1.3: Plethysmography
Revised plethysmography assessment at 
Visit 4 and Visit 6 from 30 minutes prior to 
study drug administration to 60 minutes
prior to study drug administration. 
Revised timing of Visit 4 and Visit 6 post-
dose plethysmography assessment from 2 
hours to 1-2 hours.
Revised timing so that plethysmography 
assessment would not occur at the same 
time as the 30 minute pre-dose 
spirometry assessment to allow site 
flexibility to obtain all pre-dose 
assessments.
Revised timing to allow for site 
flexibility to ensure all post-dose 
assessments are conducted in a timely 
manner.
21
Section 7.1.4: Magnetic Resonance 
Imaging
Added that MRI at Visit 3 will be 
conducted on the same day and deleted the 
text indicating that the MRI will be 
conducted 30 minutes prior to study drug 
administration.  Text now says MRI will be 
conducted prior to study drug 
administration. 
Revised timing of post-dose MRI 
assessment at Visit 4 and Visit 6 from 2 
hours to 2-3 hours.
Clarified that the MRI must be 
performed on the same day as the visit 
and removed any timing requirement for 
MRI assessment so the MRI would not 
have to be performed at the same time as 
the 30 minute pre-dose spirometry 
assessment. 
To allow site flexibility to perform all 
post-dose assessments in a timely 
manner and to not perform the MRI 
assessment any longer than 3 hours post-
dose so as not to significantly interfere 
with peak bronchodilator effect of GFF 
when the MRI is conducted. 
22
Section 7.1.5: Impedence Cardiography 
(ICG)
Revised that ICG will not be conducted 60 
minutes prior to administration of Ventolin 
HFA and Atrovent HFA to just indicate 
timing as prior to administration of these 
agents. 
To allow site flexibility so that all Visit 
2 pre-dose assessments will be 
conducted in a timely manner

timely manner. 
To allow site more flexibility to 
complete all pre- and post-dose 
assessments in a timely manner.  
23
Section 7.2.2.: Vital Sign Measurements
Clarified that at all visits (Visit 1 through 
Visit 6) , not just Visit 2, that a single vital 
sign measurement will be obtained prior to 
study drug administration and following 
completion of the last assessment of the 
visit if clinically indicated. 
Removed language that at Visits 3 to 6 a 
single vital sign measurement will be 
obtained prior to study drug administration 
and following completion of the last 
assessment of the visit. 
To provide consistency across visits 
when vital signs will be obtained.
24
Section 7.2.3: 12-Lead Electrocardiogram
Added that ECG assessments should occur 
prior to spirometry assessments.
For Visit 3, removed the within 60 minutes 
timing prior to study drug administration 
for the ECG assessment.  
For Visit 5, removed the within 30 minutes 
timing prior to study drug administration 
for the ECG assessment.
To minimize any effect of spirometry 
may have on heart rate, indicated that 
ECG should occur prior to spirometry 
assessments. 
To allow the site flexibility to obtain all 
pre-dose assessments in a timely 
manner.
25
Section 7.3.12: Use of Steroids during the 
Trial
Deleted language indicating use of 
corticosteroids for the management of 
COPD is not a reason for early termination 
and language regarding management of 
subjects’ spirometry assessments if they 
have taken corticosteroids within 14 days

Study Design:
This is a randomized, two-period, double-blind, two-treatment, chronic-dosing (7 days) 
single-center, crossover study to evaluate the treatment effect of GFF MDI (PT003) 
compared with Placebo MDI on cardiovascular hemodynamics following chronic dosing (7 
days) in subjects with moderate to severe chronic obstructive pulmonary disease (COPD). 
It is planned that approximately 40 subjects will be randomized to provide approximately 
32 study completers. 
Subjects will undergo a Screening Period of 7 to 28 days in duration. During the Screening 
Period, subjects that are receiving an inhaled corticosteroid (ICS)/long acting E2-agonist 
(LABA) will discontinue the ICS/LABA, but will continue the ICS component for the 
duration of the study.  Similarly, subjects treated with an ICS as part of their inhaled 
maintenance therapy will also be permitted to continue their ICS for the duration of the 
study.
All subjects will discontinue their previously prescribed inhaled bronchodilators and switch
to Sponsor-provided Atrovent® HFA MDI administered four times daily (QID) as COPD 
maintenance therapy during the Screening Period and during the Washout Period of the 
study. Sponsor-provided Ventolin® HFA (albuterol sulfate inhalation aerosol) administered 
as needed for control of symptoms will be provided throughout the study. At 
randomization subjects will discontinue Atrovent HFA, but will be permitted to use their 
ICS and sponsor- provided rescue inhaler (albuterol sulfate inhalation aerosol) throughout 
the study.
Subjects that meet all other entry criteria but are using certain prohibited COPD
medications must discontinue the use of prohibited medications at Visit 1 (Screening). 
Prohibited COPD medications include, but are not limited to oraOȕ2-agonists, LABAs,
long-acting muscarinic agonists(LAMA), LABA/LAMA, ICS/LABA combination 
products, cromoglycate or nedocromil inhalers, leukotriene antagonists [e.g., zafirlukast, 
montelukast, zileuton], or tiotropium [Spiriva], aclidinium [Tudorza™], and umeclidinium 
[Incruse® Ellipta®]. The use of these medications is prohibited throughout the screening 
period and the duration of the study. 
Subjects will be issued and trained on the use of the Subject Diary at Visit 1 (Screening) 
and will be instructed to collect practice data during the Screening Period (between Visit 1 
and Visit 3). Subject Diary compliance will be reviewed at Visit 3, and the subject will be 
retrained if necessary.
All subjects will be administered both GFF MDI and Placebo MDI in separate treatment 
periods. Enrollment into the active period of the study will be stratified by severity of 
disease such that half of the subjects will have moderate COPD and half will have severe 
COPD as categorized by post-bronchodilator FEV1 -<65% for moderate and 30% -
<50% for severe). The entire study period is scheduled to take approximately 12 weeks for 
each individual subject. The study is anticipated to run for approximately 6 months and 
duration should be approximately 12 months.

Duration of Treatment:
It is planned that each subject will receive study treatment over 2 Treatment Periods for 1 
week duration each.  It is anticipated that the entire study will take approximately 12 weeks 
for each individual subject from the time of Screening.
All efficacy assessments will be compared to a change from baseline. Baseline for Magnetic 
Resonance Imaging (MRI) will be defined as the pre-dose value at Visit 3. Baseline for the 
plethysmography endpoints will be defined as the pre-bronchodilator value at Visit 2. 
Baseline for the Impedance Cardiography (ICG) and spirometry endpoints will be defined 
as the average of the subject values obtained pre-dose on Day 1 of each Treatment Period 
(average of Visit 3 and Visit 5 pre-dose).  The first day of treatment in each Treatment 
Period is Day 1. Each Treatment Period is planned to be 7 days in duration occurring 
between the first and last dose which will correspond to 8 calendar days. Therefore, 
assessments collected on Day 8 will occur following 7 days of treatment.

Statistical Methods: 
Primary Efficacy Analysis: 
A mixed model will be used to evaluate the difference between treatments in the change 
from baseline in right ventricular end diastolic volume indexed to body surface area 
(RVEDVi). Baseline will use the value from Visit 3 obtained prior to the first dosing of 
Treatment Period 1. The model will include adjustment for baseline, period, and treatment. 
Sequence will only be included in the model if found to be significant (p<0.10). Subject 
will be treated as a random effect in order to model within subject correlation across the two

periods. Point estimates and 95% confidence intervals for the difference between GFF MDI 
and Placebo MDI will be produced.
Sample Size: 
Based on a two-period, two-treatment crossover study comparing Breo® Ellipta® versus 
placebo after cardiac MRI, the within-subject SD for the change from baseline in RVEDVi 
was estimated to be 7.11 mL/m2.  Assuming that 90% of the randomized subjects will 
complete the trial, the study has approximately 90% probability to demonstrate a difference 
of 5.59 mL/m2 in RVEDVi.
Safety Analyses:
Safety analyses will be based on the frequencies of adverse events (AEs).

INTRODUCTION AND STUDY RATIONALE
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 [Global Initiative for Chronic Obstructive Lung Disease [GOLD, 2016)].
Bronchodilator medications are central to the symptomatic management of COPD.  The 
SULQFLSDOEURQFKRGLODWRUWUHDWPHQWVDUHȕ2-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.
Chronic obstructive pulmonary disease (COPD) is associated with resting hyperinflation as 
a result of expiratory flow obstruction.  Although hyperinflation independently predicts 
exercise tolerance and mortality in COPD, pathophysiologic mechanisms to explain these 
findings are incompletely understood [Budweiser, 2013]. Cardiac phenotyping in COPD 
implicate a potential cardiac etiology for poor outcomes associated with hyperinflation.  
Severe emphysema is known to be associated with both decreased intrathoracic blood 
volume as well as reduced right ventricular (RV) size, suggesting hyperinflation and the 
associated increase in intrathoracic pressure may reduce RV volume through decreased RV 
preload [Jörgensen, 2007]. Gold-standard assessment of RV volume is performed using 
cardiac magnetic resonance imaging using RV end diastolic volume (RVEDV) 
[Lorenz, 1999].  In order to account for expected variances of RVEDV with body habitus, 
RVEDV is normalized to body surface area, referred to as RVEDV index (RVEDVi) 
[Chalal, 2012]. 
Treatment with combined long acting muscarinic antagonists (LAMA) and long-acting 
bronchodilators (LABA) can improve inspiratory capacity and reduce hyperinflation, 
potentially increasing pulmonary blood volume and therefore RVEDVi.  Due to the Frank-
Starling mechanism, decreasing RVEDVi will result in reduced RV stroke volume (SV) and 
cardiac output (CO), thereby resulting in multiple negative hemodynamic sequelae 
including decreased pulmonary perfusion, left ventricular (LV) filling, coronary perfusion, 
and ultimately LV forward flow.  
The direct cardiac effects of LAMA and LABA therapy suggest the potential to reverse 
these negative hemodynamic phenomena in COPD. Preclinical data from healthy canines 
indicate that acute treatment with the muscarinic antagonist glycopyrrolate increases cardiac 
index [Jacobson, 1994]. In addition, administration of the long-DFWLQJȕ2 agonist formoterol 
to explanted rat hearts increases left ventricular contractility [Watson, 2013]. Therefore, the 
improved outcomes in COPD associated with chronic LAMA/LABA therapy may be in part 
attributable to improved cardiac hemodynamics. Because improved LV forward flow should

parallel increases in LV preload and therefore RVEDVi, we propose to investigate the effect 
acute administration of combined Glycopyrronium and Formoterol Fumarate Inhalation 
Aerosol (GFF MDI) on RVEDVi in patients with moderate to severe COPD with evidence 
of resting hyperinflation. 
Pharmacologic therapy for COPD is used to reduce symptoms, reduce the frequency and 
severity of exacerbations, and improve health status and exercise tolerance.  Bronchodilators 
are the mainstay of pharmacologic treatment of COPD.  The principal bronchodilator
treatments are short-acting beta agonists (SABAs), long-acting beta agonists (LABAs), short
acting muscarinic antagonists, long-acting muscarinic antagonists (LAMAs) and
methylxanthines used as monotherapy or in combination.  In subjects with significant 
symptoms but low risk of exacerbations regular treatment with LABAs is more effective in 
the management of COPD than SABAs.  In subjects with a high risk of exacerbations 
regardless of the number of symptoms, a fixed combination of an inhaled 
corticosteroid/LABA or a LAMA is recommended [GOLD, 2016].
Fifteen different doses of GFF MDI have been evaluated in sixteen studies conducted by

Currently, three fixed-dose combinations of a LABA and a LAMA are  commercially 
available Anoro ™Ellipta® [umeclidinium and vilanterol] from GlaxoSmithKline, Utibron™ 
Neohaler® from Novartis, and Stiolto™ Respimat® from Boehringer Ingelheim.  Combivent® 
[salbutamol sulfate and ipratropium bromide] from Boehringer Ingelheim is a short-acting 
fixed dose combination of a SABA and short acting muscarinic antagonist indicated for the 
treatment of COPD and is administered as two inhalations four times daily.  Published 
studies [van Noord, 2005; van Noord, 2006; Vogelmeier, 2006] have shown that the 
complementary mechanisms of action of a LABA (formoterol fumarate) and a LAMA
(tiotropium bromide) significantly improved bronchodilation in COPD subjects compared to 
the individual agents.
Pearl Therapeutics, Inc. (hereafter referred to as Pearl) has developed a combination product, 
Glycopyrronium and Formoterol Fumarate Inhalation Aerosol (PT003, Glycopyrronium and 
Formoterol Fumarate Metered Dose Inhaler [MDI]; hereafter referred to as GFF MDI), as a 
maintenance bronchodilator treatment in subjects with COPD. Phase IIb studies were 
conducted which supported the dose selection of GFF MDI 14.4/9.6 μg BID for Phase III 
clinical studies, including this study.
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 COPD. GP

MDI has been evaluated in eight studies conducted by Pearl, including a single dose, single 
center, healthy volunteer study in Australia and seven multi-center studies in subjects with 
COPD conducted in the US, Australia, and New Zealand. This program has assessed the

Across these eight studies, approximately 350 subjects with mild to severe COPD were 
exposed to one or more doses of GP MDI. The lower end of the dose response curve has 
been adequately characterized in two chronic dose, dose-ranging studies (Studies PT001002 
and PT001003), and the findings from these two studies and the previous Phase II studies

clinical studies. 
Formoterol fumarate is a potent and selective LABA approved in many countries worldwide
for use in asthma and COPD. When inhaled, formoterol fumarate acts locally in the lung as a 
EURQFKRGLODWRU)RUPRWHUROIXPDUDWHVWLPXODWHVȕ-adrenoreceptors in the airways, inducing 
airway smooth muscle relaxation and reducing or preventing bronchoconstriction. Although 
formoterol fumarate is classified as a LABA, it has a rapid onset of action similar to SABAs. 
Formoterol fumarate is highly potent, displays high intrinsic activity, and can result in greater 
than 80% relaxation even under induced tone [Anderson, 1993]. Studies in patients with 
COPD have demonstrated that the onset of action with formoterol fumarate is faster than 
with anticholinergic agents or salmeterol and similar to that of SABAs, such as albuterol, and 
that WKHGXUDWLRQRIDFWLRQLVKRXUV>Berger, 2008]. Five large, placebo-controlled clinical 
studies of up to 12 months in duration in nearly 2500 patients demonstrated that formoterol 
fumarate is effective and well tolerated in patients with COPD [Dahl, 2001; Rossi, 2002;
Albers, 2002; Campbell, 2005; Campbell, 2007]. 
Pearl conducted three studies to confirm dose selection and safety for FF MDI. These include 
studies: PT0050801, PT0031002, and PT003005. Results demonstrated dose proportionality

substantial differences between the FF MDI treatment groups to placebo or to Foradil 12 ȝJ
and there were no important trends noted for FF MDI at any dose.

INVESTIGATIONAL PLAN
4.1
Overall Study Design and Plan
This is a randomized, double-blind, placebo-controlled, single-center, chronic-dosing 
(7 days), two-period,  two-treatment, crossover study to evaluate the treatment effect of GFF 
MDI compared to Placebo MDI on cardiovascular hemodynamics following chronic dosing 
(7 days) in subjects with moderate to severe COPD. 
It is planned to randomize approximately 40 subjects to provide approximately 32 study 
completers. 
All subjects will be administered GFF MDI and Placebo MDI in randomized order
(see Figure 1). Enrollment into the active period of the study will be stratified by severity of 
disease such that half of the subjects will have moderate COPD and half will have severe 
COPD as categorized by post-bronchodilator FEV1 -<65% for moderate and 30% -
<50% for severe).The entire study period is scheduled to take approximately 12 weeks for 
each individual subject. The study is anticipated to run for approximately 6 months and 
should not exceed 12 months. 
Screening Period:
The Screening Period will be comprised of 2 study visits. 
At Visit 1 (Screening), all subjects are to sign an informed consent form prior to the conduct
of any screening assessments.  The Investigator will obtain a medical history including 
specific cardiovascular history, COPD exacerbations within the last year, clinical laboratory 
tests, physical examination, pregnancy test and any required documentation in order to 
determine eligibility for participation (i.e., inclusion/exclusion criteria). Subjects must meet
spirometry criteria of an FEV1/FVC ratio of <0.70 and FEV1 of <65% predicted normal value 
at Visit 1 to qualify for study enrollment.  Re-screening is not allowed for subjects who do 
not meet the spirometry criteria at Visit 1.  Providing the subject meets the eligibility criteria, 
the Investigator or designee will review current COPD medications and, if necessary, will 
make arrangements to adjust the prohibited COPD therapy to protocol-allowable COPD 
therapy as described below. An ECG will also be conducted.
Subjects will undergo a Screening Period of 7 to 28 days in duration. During the Screening 
Period, subjects that are receiving an ICS/LABA will discontinue the ICS/LABA, but will 
continue an equivalent dose of the ICS component for the duration of the study. 
Similarly, subjects treated with an ICS as part of their inhaled maintenance therapy will also 
be permitted to continue their ICS for the duration of the study.
All subjects will discontinue their previously prescribed inhaled bronchodilators and switch 
to Sponsor-provided Atrovent HFA administered four times daily (QID) as COPD 
maintenance therapy during the Screening Period and during the Washout Period of the 
study. All subjects will be provided with sponsor-provided Ventolin HFA (albuterol sulfate

Inhalation Aerosol) administered PRN as needed for control of symptoms throughout the 
study. At randomization subjects will discontinue Atrovent HFA, but will be permitted to use 
their ICS and sponsor- provided rescue albuterol. 
At Visit 1 (Screening), subjects will be trained on and issued a Diary. Subjects will be 
instructed to collect practice data during the screening period (between Visit 1 and Visit 3). 
They are required to maintain a daily record of their study drug dosing, rescue medication 
use, and collection of COPD symptoms. Subjects that fail to demonstrate proper Diary 
compliance prior to Randomization (Visit 3) may not be enrolled to the study.
To allow for an adequate washout of previous maintenance medications Visit 2 will be 
scheduled a minimum of 7 days (at least 14 days if taking tiotropium) from Visit 1
(see Table 5-1 for washout period guidelines). 
At Visit 2, reversibility to Ventolin (albuterol sulfate) HFA and Atrovent (ipratropium 
bromide) HFA will be evaluated (Refer to Section 7.1.1.2). The spirometry data obtained at 
Visit 2 will be used as an inclusion criterion (Refer to Section 5.1) and to characterize the 
population. Correspondingly, at Visit 2 a series of plethysmography maneuvers will be 
performed to assess total capacity and residual volume. In addition, impedance cardiography 
(ICG) will be performed to assess cardiac output. Subject Diary compliance will be 
reviewed, and the subject will be retrained, if appropriate (Refer to Section 7.1.6).  
At Visit 2, subject’s burden of disease will be assessed using the COPD Assessment Test 
(CAT).  
Treatment Period:
After Visit 3 (Randomization), subjects that meet study inclusion criteria will be examined at 
Visit 4, Visit 5, and Visit 6. In total, each completed subject will attend 6 scheduled visits 
in this study for a maximum of 12 weeks. For the assessments scheduled at each of these 
visits, refer to the Schedule of Events (Table 8-1).
At Visit 3, all sponsor-provided Atrovent HFA provided during the screening period will be 
discontinued and collected by site personnel for accountability.
The Investigator will reevaluate the subject’s study eligibility criteria as described at Visit 1. If
a subject is assigned to GFF MDI or Placebo MDI, it will not be possible to differentiate
between these treatments since they will appear to be identical in all aspects. Randomization 
will be stratified by COPD disease severity (moderate vs. severe) to ensure even distribution 
of treatment arms within each stratum. 
Subjects will be required to take their blinded study medication twice a day.  Subjects will 
inhale 2 puffs from their MDI in the morning between 06:00 and 10:00 AM (Breakfast time) 
and in the evening between 06:00 and 10:00 PM (Dinner time).  
Pre-dose PFTs will be obtained at -60 and -30 minutes prior to dosing on Day 1 of each 
Treatment Period (Visits 3 and 5) (Refer to Section 7.1.1).

General Considerations for Treatment Visits 3 through Visit 6(in-clinic):
x
At the start of each treatment visit, prior to the administration of study drug and 
performance of any study procedures, site personnel must confirm that the subject 
withheld all COPD medications (including randomized study medication, ICS and rescue 
medication, e.g., Ventolin HFA) for at least 6 hours by confirming the last time of dosing 
for all COPD medication(s).  

Note: For subjects who inadvertently took COPD medication within 6 hours of the 
start of study procedures, the visit date must be rescheduled within the specified visit 
window as soon as it is practical.

Note: Before the in-clinic dose is administered, the site must confirm that the subject 
meets all protocol-specified requirements (e.g., FEV1 baseline criteria; see 
Section 7.1.1.1).
x
Protocol-adjusted ICS therapy as defined at Visit 1 (Screening) if any, should be 
continued and remain stable for the duration of the Study (refer to Section 5.4). 
x
Subjects must not ingest xanthine (caffeine)-containing foods and beverages for at 
least 6 hours prior to each study visit and for the duration of each study visit.
x
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.
x
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.
x
Subjects will be required to return to the clinic at approximately the same time as 
Visit 2 for all treatment visits (± 2 hours) and will be required to remain at the clinic
until completion of all protocol-defined assessments.
x
Sites should make every effort to ensure that the in-clinic dosing time is before 
approximately 11:00 AM and within 12±2 hours of the prior at home evening dosing 
time.
x
The in-clinic dosing time for study drug (GFF MDI or Placebo MDI) will be recorded 
as the time of administration of the second puff.
x
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 to remind the subject of 
the following:

Subjects should take their last dose the evening before the scheduled visit;

To bring their study medications and Subject Diary with them to the clinic and to 
withhold all COPD medications (including ICS and phosphodiesterase inhibitors) 
or for at least 6 hours prior to PFTs;

Refrain from ingesting xanthine (caffeine)-containing foods and beverages for at 
least 6 hours prior to each study visit and for the duration of each study visit;

Page 33 of 121

Refrain from smoking for at least 4 hours prior to the study visit and throughout 
the duration of each study visit.
x
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 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.
Note: If, during a Day 8 visit, a subject requires rescue Ventolin HFA and the MRI 
has not been obtained, the visit needs to be rescheduled.
x
Subjects will complete all Visit 6 (Final Study Visit) assessments and will be 
scheduled for a post-study follow-up telephone call at least 14 days from Visit 6.

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 Visit 6 or to whenever the subject discontinues 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 from the study.  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 must not ingest xanthine (caffeine)-containing foods 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.
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 3) will result in a screen failure.  Smoking status changes during the 
Treatment Period will be captured in the CRF, 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 and throughout the
duration of each study visit.  Study participants may utilize various nicotine replacement 
treatments such as chewing gum and patches (PRN), 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 
cigarette smoking except for the calculation of pack-year history.
5.7
Reasons and Procedures for Early Termination from the Study
5.7.1 Reasons for Discontinuation
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.  If a subject is lost to follow up 
(i.e., fails to return for study visits), reasonable efforts must be made to contact the subject 
and complete study termination procedures.  All subjects who discontinue the study because 
of AEs will be followed up at suitable intervals in order to evaluate the course of the AE and 
to ensure the reversibility or stabilization of the abnormality.  All subjects who prematurely 
discontinue the study after Randomization, regardless of the cause, should undergo only the 
assessments outlined in Section 8.7 on the date of discontinuation.
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 study. The changes of 
concern include:
x
Following dosing, a heart rate increase of greater than 40 bpm from the pre-dose 
value obtained on that specific test day and the measured value is also >120 bpm.
x
Following dosing, a systolic BP (SBP) increase of more than 40 mmHg from the pre-
dose value obtained on that specific test day and the measured value is also >160 
mmHg.
x
Decrease in creatinine clearance to a value below 30 mL/minute using CKD-EPI 
formula clinically relevant change from baseline as determined by the Investigator.
x
Calculated QTcF intervals >500 msec, and have increased by 60 msec or more over 
baseline value obtained at Randomization (Visit 3).

is beyond normal day-to-day variations, is acute in onset, and may warrant a change in 
regular medication.  The severity of COPD exacerbations will be classified as follows:
-
Mild:  Exacerbations that do not require systemic steroids or antibiotics and do not 
result in hospitalization or death
-
Moderate:  Exacerbations that require treatment with systemic steroids and/or 
antibiotics, and do not result in hospitalization or death
-
Severe:  Exacerbations that result in hospitalization or death
x
Subjects who failed to meet FEV1 baseline stability criteria may be discontinued at 
the investigators discretion (see Section 7.1.1.1)
x
An Investigator may choose to discontinue a subject from study participation at any 
time or for any reason, with sufficient notice by the Investigator, as per the terms of 
the contract with Pearl. The reason for discontinuation will be documented in the 
source documents.
x
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 timeframe that is compatible with the subjects’ 
well-being.
If a subject requires the following prohibited medications, they should be discontinued from
the study:

LABELING, PACKAGING, STORAGE, DISPENSING, AND 
RETURN OF CLINICAL SUPPLIES
6.1
Subject Information
Clinical supplies will be packaged to support enrollment of the study.  Treatments will be
blinded in terms of dose administered.  The characteristics of the single GFF MDI dose that
will be administered during the study are provided in Table 6-1.
An envelope-based randomization system will be used to assign blinded study medication to 
subjects. The site will receive two large portfolio envelopes aligned to the two subject 
stratification criteria, with one envelope containing subject randomization envelopes for 
subjects with Moderate COPD, and the other containing subject randomization envelopes 
for subjects with Severe COPD. Each large portfolio envelope contains a series of subject 
randomization envelopes, identified by a unique randomization number and organized in 
sequential order. Only subjects eligible for randomization will be assigned the next-in-
sequence randomization envelope, drawn from the large portfolio envelope specific to the 
subject’s stratification (Moderate or Severe COPD).
The subject randomization envelope contains two smaller envelopes, one marked Treatment 
Period 1 and the other marked Treatment Period 2. The Treatment Period 1 envelope 
contains a form which provides the blinded component IDs to be assigned to the subject for 
Visit 3 and Visit 4 (specific to blinded treatment assigned for Treatment Period 1). The form 
will also indicate a “Reserve” replacement component ID which will be kept at the site and 
will not be dispensed to the subject unless the subject requests the replacement component 
ID in the case of an emergency, and will return to the site to obtain the replacement 
medication. After the washout period from Treatment Period 1, the site would open the 
Treatment Period 2 envelope and follow the same process as for Treatment Period 1 and 
dispense component IDs aligned to the second treatment (blinded) independently at Visit 5 
and Visit 6. A replacement component ID for Treatment Period 2 will also be provided, but 
will only be dispensed at the request of the subject in case of emergency.
Twenty of the
planned 40 subjects will be included in each treatment sequence. Should all subjects
complete the study, the design is balanced for period and first-order carryover effects.
For each subject, single dose administration of study drug during each of the two Treatment
Periods should occur at approximately the same time of day.
6.2
Product Descriptions and Primary Packaging and Labeling 
Information
Investigational materials will be packaged by Pearl as summarized in Table 6-1. Atrovent 
(ipratropium bromide) HFA and Ventolin HFA supplies will be supplied as open-label MDIs.

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 stored below 25° C (77° F) in a dry place.  Excursions permitted 
up to 30° C (86° F).
Ventolin® HFA supplies: Store between 15°C and 25°C (59°F and 77°F).  Store the inhaler

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 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 
randomized/continue with the study.  Any deviation from this must be discussed with the 
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 the site’s regulatory binder. Pearl will contact the site 
to evaluate the nature of the complaint and determine what further action is needed

STUDY PROCEDURES
A time and events schedule is provided in Table 8-1. Detailed schedules for pre- and
post-dose procedures to be performed at Screening and at each treatment visit are provided in 
Table 8-2 and Table 8-3, respectively.
Every effort should be made to conduct study assessments at approximately the same time 
for a given subject across each treatment period.  
All pre-dose assessments for Visit 3 and Visit 5 are recommended to be conducted in the 
following order: vital signs, clinical laboratory assessments, ICG, ECG, MRI (Visit 3 only) 
and spirometry (IC, when conducted should be obtained prior to all other spirometry
assessments).
All pre-dose assessments for Visit 4 and Visit 6 are recommended to be conducted in the 
following order: vital signs, clinical laboratory assessments, ICG, plethysmography, and 
spirometry (IC, when conducted should be obtained prior to all other spirometry
assessments).
All post-dose assessments for Visit 4 and Visit 6 are recommended to be conducted in the 
following order: ICG, ECG, spirometry (IC, when conducted should be obtained prior to all 
other spirometry assessments), plethysmography, and MRI.
7.1
Efficacy Assessments
7.1.1 Pulmonary Function Tests (Spirometry)
Forced expiratory spirometry for derivation of FEV1 and FVC, will be assessed using a 
spirometer that meets or exceeds minimum performance recommendations of the ATS (Refer 
to Appendix 1).
The volume accuracy of the spirometer is to be checked daily using a 3 L syringe across 3 
flow ranges e.g., at <2 L/sec, 4-6 L/sec and >8 L/sec 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 2, Spirometry Assessment 
Criteria).
All PFTs including FEV1 and FVC as defined in ATS/ERS guidelines will be performed in 
accordance with ATS criteria (Miller, 2005).
To standardize spirometry, the site will use the identical spirometry systems across all 
subjects and study visits. Site will document in their site study file and provide the sponsor a 
listing the manufacture, make and model of spirometry equipment used for this study. Site 
will be responsible for maintaining calibration and maintenance records of all spirometry 
equipment used for this study and provide these records to the sponsor upon request.

Note: Spirometry must meet both acceptability and repeatability criteria (Refer to exclusion 
criterion 3i).
Spirometry assessments will be obtained at:
x
Visit 1
x
At Visit 2, pre-bronchodilator spirometry assessments will be conducted 30 minutes prior 
to Ventolin HFA and Atrovent HFA administration and at 30 minutes post Ventolin HFA 
and Atrovent HFA administration. At Visits 3 and 5 (Day 1 of each Treatment Period), 
spirometry will be conducted 60 minutes and 30 minutes prior to study drug 
administration.
Note: The mean of the -60 minutes and -30 minutes pre-dose spirometry assessments 
conducted at Visit 3 and Visit 5 will be used to establish baseline FEV1 and FVC.
x
At Visits 4 and 6 (Day 8 of each Treatment Period), spirometry will be conducted 30 
minutes prior to study drug administration and at 1 hour post study drug administration.
7.1.1.1
FEV1 Baseline Stability Criteria
It is important to ensure that the baseline FEV1 is stable and reflective of the subject’s COPD 
severity prior to continuation in the second treatment period. As such, the baseline FEV1 at 
Visit 5 must be within ±20% or 200 mL of the pre-dose FEV1 obtained at the Randomization 
Visit (Visit 3). 
At Visit 5, if the pre-dose FEV1 average is outside of the ±20% or 200 mL range, but the 
30-minute pre-dose assessment is within ±22% or 220 mL, then another assessment may be 
conducted 30 minutes later. If the last two assessments meet the reproducibility requirements 
(i.e., within ±20% or 200 mL), the initial 60-minute pre-dose assessment will not be used and 
the last two assessments will be used to establish the eligibility criteria. 
If the baseline FEV1 is not within ±20% or 200 mL, the visit may be rescheduled (for a 
maximum of three attempts) at the Investigator’s discretion (e.g., within 1 week), or the 
subject may be discontinued.

7.1.2 Inspiratory Capacity (IC)
On all test days throughout the conduct of the study, IC assessments will be conducted at the 
same time points, and just prior to all other spirometry assessments.  The average of the two 
assessments on Day 1 of each Treatment Period will be used to establish the baseline IC.  
Specifically, IC data will be analyzed for secondary and other assessments.
x
On Day 1 of each Treatment Period (Visits 3 and 5): IC assessments will only be 
conducted 30 minutes prior to study drug administration. 
x
On Day 8 of each Treatment Period (Visits 4 and 6): IC assessments will be conducted 30 
minutes prior to study drug administration and at 1 hour post study drug administration.  
All subjects will be instructed on the performance of the IC maneuver. Subjects must be 
tested in the seated position wearing a nose clip with no air leaks between the mouth and 
mouthpiece.  Subjects should be relaxed with shoulders down and asked to breathe regularly 
for several breaths until the end-expiratory lung volume is stable (this usually requires at 
least five tidal maneuvers). They are then urged to take a deep breath to total lung capacity 
with no hesitation. From at least three acceptable trials, the two largest IC measurements 
should agree within 5% or 200 mL, both of these IC values will be captured and analyzed.
7.1.3 Plethysmography 
Plethysmography is the measurement of changes in the volume of organs or other body parts, 
particularly those changes resulting from blood flow. It has been demonstrated be a reliable 
lung tests that assess lung diseases, which are often associated with a decrease in total lung 
capacity (TLC). Plethysmographic measurements are based on defining the relationship 
between the pressure and volume of a gas. The test also follows the course of a disease and 
its response to treatment, measures your resistance to airflow and measures your response to 
bronchodilator medications.
Assessments will be performed using a Plethysmograph. To standardize plethysmographic 
measurements, the site will use the identical plethysmography systems across all subjects and 
study visits. Site will document in their site study file and provide the sponsor a listing the 
manufacture, make and model of plethysmography equipment used for this study. Site will 
be responsible for maintaining calibration and maintenance records of all plethysmography 
equipment used for this study and provide these records to the sponsor upon request.
Measurements will be classified performed as follows:

On Day 1 of each Treatment Period (Visits 3 and 5), ICG assessments will be conducted 
prior to study drug administration
x
On Day 8 of each Treatment Period (Visits 4 and 6) ICG assessment will be conducted
prior to study drug administration, 30 minutes and 1 hour post study drug administration 
7.1.6
Subject Diary Data Collection
Subjects will be provided with a Diary to be completed BID to record their study drug dosing, 
and rescue medication use. 
x
Starting at Screening (Visit 1) and for the duration of the study, subjects will be issued 
and trained on diary collection. They will be asked to maintain a daily record of their 
study drug dosing, and rescue medication use 
Site personnel will review the Diary entries during the Screening Period to assess the 
subject’s compliance and understanding of how to use the Diary to maintain a daily record of 
their study drug dosing, and rescue medication use 
x
At the Randomization Visit (Visit 3), subjects should meet the compliance requirement of 
70% subject completion of Diary assessments in the last 7 days preceding the 
Randomization Visit to be randomized in the study. Subjects who fail to demonstrate 
proper Diary compliance prior to Randomization must be screen failed. 
Note: In-clinic dosing times will be documented in the source by the site staff and will not 
be entered by subjects into their Diary.

x
At all treatment visits (Visits 3 to 5) site personnel must review the Diary prior to dosing 
study drug in the clinic Table 8-1)
The patient is to return the completed diary at each scheduled visit. The study coordinator 
will be responsible for reviewing the diary for completeness and accuracy with the patient. 
All fields should be completed by the patient. The patient will sign (initial) and date each 
page of the diary on the day it was completed and the study coordinator will initial and date 
each diary page at the site visit when the diary is returned to validate the authenticity of the 
entries. If discrepancies or omissions of data are observed at this review, the patient, not the 
study coordinator, should make the corrections. The patient should draw a single line through 
the error and initial and date all corrections. The patient should make all entries in the diary 
in blue or black ink.
Furthermore, in conjunction with review of the diary, the patient will be prompted by the 
study coordinator about missed doses of study medication and additional COPD medication. 
The patient should be instructed to record this information in the diary. Missing data from 
>24 hours prior to the site visit should be left blank. Subjects should be instructed to record 
the time and doses of study medication and rescue medication in hours and minutes a.m. or 
p.m., not in 24-hour clock time. Study sites will enter the Diary information into the eCRF.
7.1.7 Rescue Ventolin HFA Use
The subject will record the total number of puffs of rescue Ventolin HFA used in the Diary 
on a PRN basis.  The number of puffs of rescue Ventolin HFA to be recorded is the number of 
actuations of the canister.  For example, when rescue Ventolin HFA is required and 
two actuations are inhaled, this should be recorded as two puffs.  In the event the subject 
requires four actuations, this should be recorded as four puffs.  Subjects requiring more than 
eight puffs per day on three or more consecutive days with worsening symptoms should 
contact the site.
7.1.8 Medication Compliance 
Time of dosing with study medication will be recorded in the subject’s Diary 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.
7.1.9 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.

Each test should be labeled with the study number, patient initials, subject number, date, and 
kept in the source documents at the study site. 
QT intervals and calculated QTcF intervals will be reviewed and checked for gross 
inaccuracies by the Investigator or designated ECG reviewer.  If the calculated QTcF 
intervals are > 500 msec, and have increased by 60 msec or more over test day baseline 
value, the Investigator will make a determination on the suitability of continuing the subject 
in the study.  If QTcF interval prolongation exceeding these limits is verified during 
treatment, the subject’s medical history should be examined closely for risk factors that may 
have contributed to the event, including evidence of prior genotyping for hereditary long QT 
syndromes, if appropriate.
Any sign of arrhythmia should be noted.  During treatment, any indication of Torsade de 
Pointes, a polymorphic ventricular tachyarrhythmia that appears on the ECG as continuous 
twisting of the vector of the QRS complex around the isoelectric baseline, must be recorded 
as an AE and reported to the Pearl Medical Monitor. 
All such subjects, including subjects with cardiac arrhythmias, should be monitored closely.  
If appropriate, ECG monitoring should be performed until the QT and QTcF interval and 
waveform morphology have returned to normal. If the prolongation or abnormal rhythm 
persists, the Pearl Medical Monitor must be contacted immediately. 
All ECG assessments should occur prior to spirometry assessments.
x
A single 12-Lead ECG will be obtained at Visit 1 (Screening) and the Treatment 
Discontinuation/Withdrawal Visit, if applicable

7.3
Adverse Events
7.3.1 Performing Adverse Events Assessments
The Investigator is responsible for promptly documenting and reporting all AEs observed 
during the study in the subject’s CRF 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 7.3.9) 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.
In the case of SAEs, after discussing the details of the event, the Investigator and the Medical 
Monitor may discontinue the subject prematurely.
7.3.2 Adverse Event Definitions
The following definitions of terms are guided by the International Conference on 
Harmonization, the U.S. Code of Federal Regulations [21 CFR 312.32] and European Union 
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 (eg, an abnormal laboratory finding), symptom, 
or disease temporally associated with the use of a drug, without any judgment about 
causality.  An adverse event can arise from any use of the drug (eg, 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:
x
Any symptom or condition not previously reported by the subject (medical history).
x
An exacerbation of a pre-existing symptom or condition.
x
A significant increase in frequency or intensity of a pre-existing episodic event or 
condition.
x
A drug interaction
x
A condition first detected or diagnosed after study drug administration even though it 
may have been present prior to the start of the study.

Page 65 of 121
An AE does not include:
x
Medical or surgical procedures (e.g., surgery, endoscopy, tooth extraction, blood 
transfusion); the condition that leads to the procedure are an AE (e.g., bleeding 
esophageal varices, dental caries).
x
Overdose of either study drug or concurrent medication without any clinical signs or 
symptoms.
x
Non-clinically significant abnormal laboratory values.  (If accompanied by 
signs/symptoms, the signs or symptoms are considered an AE).
7.3.3 Pre-Randomization Adverse Events
Adverse events that occur between the time subject signs the informed consent form for the 
study and the time when that subject is randomized will be summarized as medical history 
and not as a treatment emergent adverse event unless the event meets the definition of an 
SAE as defined below.
7.3.4 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.
7.3.5 Relationship
The relationship of each adverse event 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.

Page 66 of 121
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.
7.3.6 Chronic Obstructive Pulmonary Disease Exacerbations
All COPD exacerbations must be captured using the COPD Exacerbation eCRF. 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). 
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.
7.3.7
Adverse Events of Special Interest
Paradoxical bronchospasm may occur following inhalation from an MDI. 
Monitoring for paradoxical bronchospasm will occur at each visit during the Treatment 
Period (Visits 4 through 6).  In this study, paradoxical bronchospasm is defined as a 
reduction in FEV1 of >20% from test day baseline (i.e., the mean FEV1 values obtained 60 
and 30 minutes prior to study drug administration) with associated symptoms of wheezing, 
shortness of breath, or cough.  All AEs and SAEs will be recorded, as appropriate.
7.3.8 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 blood urea nitrogen and 
creatinine in the setting of an AE of renal failure, or decreased hemoglobin in a case of 
bleeding esophageal varices). However, when an isolated laboratory abnormality is 
considered clinically significant by the Investigator, it must be reported as an AE.
Criteria for a “clinically significant” laboratory abnormality are:
x
A laboratory abnormality that leads to dose-limiting toxicity (e.g., an abnormality that 
results in study drug dose reduction, suspension, or discontinuation)
x
A laboratory abnormality that results in any therapeutic intervention (i.e., concomitant 
medication or therapy)
x
Any other laboratory abnormality judged by the Investigator to be of any particular 
clinical concern (e.g., significant fall in hemoglobin not requiring transfusion)

Clinical Trial Protocol: PT003017-02
Version 3.0, 26 September 2016
Confidential and Proprietary
Page 67 of 121
For laboratory abnormalities that do not meet the above criteria but are outside of the 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.
7.3.9 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:
x
Death
x
A life-threatening AE 
x
In-patient hospitalization or prolongation of existing hospitalization 
x
A persistent or significant incapacity or substantial disruption of the ability to conduct 
normal life functions
x
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 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 adverse event or suspected adverse reaction is considered “life-threatening’ if, in the view 
of the Investigator or Sponsor, its occurrence places the subject or subjects 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 (IB) or is not listed at the specificity or severity that has been 
observed.
7.3.9.1
Reporting 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 
Pearl no later than 24 hours after the Investigator recognizes/classifies the event as a serious 
adverse event. 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 the SAE to Pearl Pharmacovigilance or designee within two

working days after he/she receives that information. This follow-up information may include 
copies of hospital records, case reports, and autopsy reports, and other pertinent documents.
Post-study SAEs occurring up to 14 days following the last dose of study drug must be 
reported to Pearl Pharmacovigilance as described in Section 7.3.9.3.
The Investigator is responsible for continuing to report to Pearl or designee any new or 
relevant follow-up information that he/she learns about the SAE.
7.3.9.2
Supplemental Investigations of SAEs
The Investigator and supporting personnel responsible for subject care should discuss with 
the Pearl Medical Monitor or designee 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.
7.3.9.3
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. 
7.3.9.4
Notification of Post-Study Serious Adverse Events
Investigators are not obligated to actively follow subjects after the completion of the study.  
However, if the Investigator becomes aware of a post-study SAEs occurring up to 14 days 
following the last dose of study drug, the SAE 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.
7.3.9.5
Investigational Research Board/Independent Ethics Committee Notification of 
Serious Adverse Events
The Investigator is responsible for promptly notifying her/his Institutional Review 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 informed consent form or other measures based on its 
review of an SAE report.
7.3.9.6
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.

Page 69 of 121
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.
7.3.10 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 and Primary Packaging and Labeling 
Information) 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 or designee. The Investigator should refer to the relevant 
document(s) for detailed information regarding warnings, precautions, contraindications, 
adverse events, and other significant data pertaining to the study drug(s) being used in this 
study. Such document may include, but not be limited to, the Investigator’s brochure for GFF 
MDI.
7.3.11 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 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.
7.3.12 Use of Steroids during the Trial
At each visit, subjects will be asked whether they have been administered oral, intramuscular 
or intravenous corticosteroids since last visit.  Use of corticosteroids should be documented.  
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 in the study.
7.4
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’ well-being.

PLANNED STATISTICAL METHODS
9.1
Introduction
This study will be conducted as a randomized, double-blind, single-center, chronic-dosing (7 
days), two-period, two-treatment, crossover study evaluating the effect of the following 
treatments on cardiovascular hemodynamics in approximately 32 subjects:
•
*))0',ȝJ%,'
•
Placebo MDI BID
The primary objective of this study is to evaluate the effect of GFF MDI on cardiovascular 
hemodynamics following chronic dosing (7 days) in subjects with moderate to severe COPD. 
9.2
Protocol Variables
9.2.1
Efficacy Endpoints
All efficacy assessments will be compared to baseline values. Baseline for the MRI endpoint 
will be defined as the pre-dose value at Visit 3. Baseline for the plethysmography endpoints 
will be defined as the pre-bronchodilator value at Visit 2. Baseline for the ICG and 
spirometry endpoints will be defined as the average of the subject values obtained pre-dose 
on Day 1 of each Treatment Period (average of Visit 3 and Visit 5 pre-dose). For spirometry 
endpoints, the mean of the -60 and -30 minute values for each visit will be obtained prior to 
averaging across visits. The first day of treatment in each Treatment Period is Day 1.  Each 
Treatment Period is planned to contain 7 days between the first and last dose corresponding 
to a span of 8 calendar days.  Therefore, assessments collected on Day 8 will occur following 
7 days of treatment. 
The MRI endpoints RVEDV, LVEDV, LVESV, and RVESV will be normalized to body 
surface area (BSA) to provide the indexed counterpart, e.g.: 
RVEDVi = RVEDV / BSA 
Prior to calculating the change from baseline, the baseline and post-dose RVEDV values will 
each be normalized separately using the respective BSA values.

Analysis
9.3.1
Efficacy Analysis
9.3.1.1
Primary Efficacy Analysis
A mixed model will be used to evaluate the difference between treatments in the change from 
baseline in RVEDVi. Baseline will use the value from Visit 3 obtained prior to the first 
dosing of Period 1. The model will include adjustment for baseline, period, and treatment. 
Sequence will only be included in the model if found to be significant (p<0.10). Subject will 
be treated as a random effect in order to model within subject correlation across the two 
periods. Point estimates and 95% confidence intervals for the difference between GFF MDI 
and Placebo MDI will be produced. P-values will thus be reported as two-sided. The primary 
null (H0) and alternative (H1) hypotheses with μ representing the mean are:
H0: μGFF = μplacebo
H1: μGFF  μplacebo
The primary analysis will use the modified Intent-to-Treat (mITT) Population.  Analyses 
using the Intent-to-Treat (ITT) Population will be considered supportive.
9.3.1.2
Secondary Efficacy Analysis
Change from baseline in each of the secondary efficacy endpoints will be analyzed using a 
similar mixed model as for the primary endpoint, change in RVEDVi. In addition, since there 
are two responses (30- and 60-min post dose) per period for PVR, an unstructured covariance 
matrix will be fit to the repeated measures within a subject-period for this endpoint. If 
sequence is found to be significant (p<0.10) in the primary analysis model, a term for 
sequence will also be included in each of the models for the secondary endpoints. Baseline 
for the MRI endpoints will use the value from Visit 3 obtained prior to the first dosing of 
Period 1. Baseline for the ICG endpoint, pulmonary vascular resistance, will be defined as 
the average of the subject values obtained pre-dose on Day 1 of each Treatment Period 
(average of Visit 3 and Visit 5 pre-dose). Point estimates, 95% confidence intervals and two-
sided p-values will be reported for the difference between GFF MDI and Placebo MDI.

The secondary analyses will use the modified Intent-to-Treat (mITT) Population.  Analyses 
using the Intent-to-Treat (ITT) Population will be considered supportive.
9.3.1.3
Other Efficacy Analysis
Change from baseline in each of the other efficacy endpoints will be analyzed using a similar 
mixed model as for the primary endpoint, change in RVEDVi. For the ICG endpoint of 
change in right ventricular stroke volume, an additional unstructured covariance matrix will 
be fit to the repeated measures within a subject period. If sequence is found to be significant 
(p<0.10) in the primary analysis model, a term for sequence will also be included in each of 
the models for the other efficacy endpoints. Baseline for the plethysmography endpoints will 
use the pre-bronchodilator value at Visit 2. Baseline for the ICG and spirometry endpoints 
will be defined as the average of the subject values obtained pre-dose on Day 1 of each 
Treatment Period (average of Visit 3 and Visit 5 pre-dose). For spirometry endpoints, the 
mean of the -60 and -30 minute pre-dose values for each visit will be obtained prior to 
averaging across visits. Point estimates, 95% confidence intervals and two-sided p-values 
will be reported for the difference between GFF MDI and Placebo MDI.
The other efficacy analyses will use the Intent-to-Treat (ITT).
9.3.2
Safety Analysis
9.3.2.1
Adverse Events
Adverse events during each Treatment Period will be summarized by the number of subjects 
experiencing an event.  They will be tabulated at the level of the Medical Dictionary for 
Regulatory Activities (MedDRA) preferred term, and the MedDRA system organ class.  The 
version of MedDRA current at the time of database lock will be used for the final analysis of 
data.  Tabulations will be broken down by severity, seriousness, AEs leading to 
discontinuation, and by relationship to study drug. No hypothesis tests will be performed.  
Tables will show the overall incidence of AEs, and the incidence for each treatment.
9.4
Randomization
Subjects will be randomly assigned using the treatment sequence AB or BA in a 1:1 ratio 
where A= GFF MDI 14.4/9.6 μg BID and B= Placebo MDI BID, respectively. All subjects 
who complete the study will receive both treatments. Randomization will be stratified by 
severity of disease such that half of the subjects will have moderate COPD and half will have 
severe COPD as categorized by post-bronchodilator FEV1-<65% for moderate and 
30% -<50% for severe).
9.5
Experimental Design
The experimental design was chosen to be balanced with respect to period and first-order 
carryover effects.

9.6
Sample Size Consideration
Based on a two-treatment, two-period crossover study comparing Breo® Ellipta® versus 
placebo after cardiac MRI (Stone, 2015), the within-subject SD for the change from baseline 
in RVEDVi was estimate to be 7.11 mL/m2.  Assuming that 90% of the randomized subjects 
will complete the trial, the study has approximately 90% probability to demonstrate a 
difference of 5.59 mL/m2 in RVEDVi.
9.7
Data Validation and Transformation
In general, the data captured within this study are expected to follow a normal distribution.  
However, under certain circumstances, (e.g., during a COPD exacerbation unrelated to 
treatment) extreme and 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 will include production of normal probability plots, 
kernel density estimates, and normal order outlier statistics.  Based on this blinded 
evaluation, if a single or small number of extreme 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; 
however if these values cannot be corrected, they will be considered for removal from analysis.
9.8
Analysis Plan 
All analyses will be specified in a detailed Statistical Analysis Plan (SAP) that will include 
table and data listing shells with mock graphical representations.  The SAP will be signed 
before database lock and unblinding.  
9.9
Study Populations
The following analysis populations are defined in this study:
x
The ITT Population is defined as all subjects who are randomized to treatment.  
Subjects will be analyzed according to the treatment assigned per the sequence 
randomization regardless of the treatment actually received.  
x
The mITT Population is a subset of the ITT Population including subjects who received 
treatment and have post-treatment efficacy data from both Treatment Periods.  Data 
judged to be impacted by major protocol deviations will be determined prior to 
unblinding and excluded.  Statistical tabulations and analyses will be by randomized 
treatment, but data obtained after subjects receive an incorrect treatment will be excluded 
from the affected periods.
x
The Safety Population is defined as all subjects who are randomized to treatment and 
receive at least one dose of the study treatment.  Statistical tabulations will be by the 
treatment actually received.

Page 87 of 121
x
The Not Randomized Population is defined as subjects who did not receive a 
randomization number and therefore did not receive a dose of study treatment 
(e.g., subjects who were screen failures or stopped participation prior to having been 
randomized). 
Analyses will be performed as follows:
Demographics will be summarized for the ITT, mITT, Safety, and the Not Randomized 
Populations.  Extent of exposure will be summarized for the Safety Population.  The Safety 
Population will be used to summarize safety.
Analyses for the primary and secondary efficacy endpoints will be performed for the mITT 
and ITT Populations, with the mITT Population being considered the primary population for 
these analyses. Analyses for the other efficacy endpoints and the exploratory endpoints will 
be conducted with the ITT Population.
9.10 Handling of Missing Data
All observed values will be included in the ITT Population for the efficacy and exploratory 
analyses. All observed values meeting specified criteria will be included in the mITT 
Population.
Missing data will be maintained as missing in the analysis datasets, unless specified 
otherwise. For variables where missing data is imputed, the analysis dataset will contain a 
new variable with the imputed value and the original variable value will be maintained as 
missing.
9.11
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)

Appendix 1
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 “ATS/ERS Task Force: Standardization of Lung Function Testing:  Number 2 in 
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 
eight 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 trials, 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 (ie, 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 three 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 three relatively constant flows at a low flow, then three at a mid-range flow and 
finally three 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 A1-1, 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.

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, ie, the volume-WLPHFXUYHVKRZVQRFKDQJHLQYROXPH/IRU
1s, 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 trials with observed limitations.

back extrapolation through the steepest part of the curve, where flow is peak expiratory flow 
(PEF), to determine the new “time zero”. Forced vital capacity (FVC)-4.291 L; back 
extrapolated volume (EV) – 0.123 L (2.9% FVC): back extrapolation line through PEF.
Between-Maneuver FEV 1 Baseline Stability Criteria
After three acceptable spirograms have been obtained, apply the following tests

The two largest values of FVC must be within 0.150 L of each other
The two 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).

Subject Instructions for Use of GFF and Placebo MDI
Before using GFF MDI and Placebo MDI
1. Take the inhaler out of the foil pouch.  Safely throw away the pouch and the drying 
packet that comes inside the pouch.  Check the indicator at the top of the canister; the 
indicator should read as shown in Figure 2.
Figure 2. Indicator at Top of Canister
2. Take the cap off the inhaler and inspect the front of the inhaler and make sure there is 
nothing inside the mouthpiece of the inhaler.  Make sure the canister is fully and firmly 
inserted into the actuator.
3. The inhaler should be stored at room temperature.
How to prime GFF MDI and Placebo MDI
1. The inhaler 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.  
2. Take the cap off the mouthpiece of the actuator.
3. To prime the inhaler, gently shake the inhaler for 5-10 seconds and then spray once into 
the air away from yourself and others.  
4. Wait approximately 5-10 seconds and repeat the process three more times.
How to take a dose from GFF MDI and Placebo MDI
Steps 3-6 below should be done one after the other.
1. Take the cap off the mouthpiece of the actuator.
2. Hold the inhaler with the mouthpiece down.
3. Shake the canister for 5-10 seconds.
4. Breathe out fully through mouth, expelling as much air from the lungs as possible. 
5. Tilt head back slightly, place the mouthpiece into mouth, and close lips around it.  To 
allow the medication to enter the lungs, keep tongue flat on the floor of your mouth.  
Keep the mouthpiece at the bottom and the dose indicator at the top.

6. While breathing in deeply and slowly, press down on the center of the dose indicator with 
finger.  Fully depress the canister until it stops moving in the actuator while delivering
the dose.  Note: It is normal to hear a soft click from the indicator as it counts down 
during use.
7. Hold breath as long as possible, up to 10 seconds, and then breathe normally.
8. Repeat steps 3 to 7, with gentle shaking for 5-10 seconds before the second spray.
9. Put the cap back on the mouthpiece after every time the inhaler is used, and make sure it 
is firmly seated in place.
How to clean GFF and Placebo MDI
It is very important to keep the plastic actuator clean so the medicine does not build-up and 
block the spray.  The inhaler may stop spraying if it is not cleaned correctly.  Do not clean 
the metal canister or let it get wet.
Wash the actuator once a week for the first three weeks as directed below.
1. Take the canister out of the actuator, and take the cap off the mouthpiece. 
2. Wash the actuator through the top of the actuator with warm running water for 
30 seconds (Refer to Figure 3).  
Figure 3. Wash Actuator through Top of Actuator
3. Then wash the actuator again through the mouthpiece (Refer to Figure 4).

Figure 4. Wash Actuator through Mouthpiece
4. Shake off as much water from the actuator as you can.  Look into the mouthpiece to make 
sure any medicine build-up has been completely washed away.  If there is any visible 
build-up, repeat steps 2 and 3.
5. Let the actuator air dry completely, such as overnight.
6. When the actuator is dry, put the canister in the actuator, making sure the canister is fully 
and firmly fitted into the actuator.  Shake the inhaler gently for 5-10 seconds and spray it 
2 times into the air away from your face, shaking gently 5-10 seconds before each spray.  
Put the cap back on the mouthpiece.
If the actuator becomes blocked
Blockage from medicine build-up is more likely to happen if the actuator is not routinely 
cleaned and the actuator is not air-dried completely.  If the actuator gets blocked so that little 
or no medicine comes out of the mouthpiece, wash the actuator as described in cleaning steps 
1-6.
If the inhaler is needed before the actuator is completely dry, shake as much water off the 
actuator as possible.  Put the canister in the actuator and make sure it fits firmly.  Shake the 
inhaler gently for 5-10 seconds and spray it 2 times into the air away from your face, shaking 
gently 5-10 seconds before each spray. Then take the dose as prescribed and described 
above.  Then clean and air-dry it completely.
How to read the inhaler dose indicator
The inhaler is fitted with a dose indicator which shows how much medicine is left during use.  
The dose indicator display will move after every tenth puff.  The dose indicator pointer will 
start to point to the red area when there are 20 puffs remaining.  This means that the inhaler 
needs to be replaced soon.
