Section 4.1 Overall Study Design and Plan
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. At 
Visit 1 (Screening), eligible subjects who are not 
using a prohibited COPD medication (refer to 
Table 5-1) and meet all other entry criteria will 
return to the clinic in 7 to 14 21 days after 
Screening for Visit 2 (Randomization Visit). For

the CT-scans are taken, spirometry and body 
plethysmography will be performed; the 
inhalation profile will be measured with the body 
plethysmograph and respiration belts. and body
plethysmography will be performed. The subject's 
inhalation profile will be measured in order to draw 
an airflow versus time curve. At the moment of this 
measurement the signal from the respiration belt, 
used for the measurement of the inhalation profile 
during the study drug administration, will also be

Section 4.1 Overall Study Design and Plan
On Visit 3 (Day 15 ± 5 of TP 1) subjects will 
perform a spirometry test and will undergo Visit 3 
protocol-defined pre-dose assessments (refer to 
Table 8-11 and Table 8-13). The site personnel will 
wait 1 hour after the administration of study drug 
before initiating post-dose assessments. Post-dose 
assessments need to be completed within 2.5 hours 
after dosing the subject. Study drug will be collected. 
Prior to discharge from the study clinic, Study 
drug will be collected, subjects will be discharged 
from instructed to undergo a study drug washout 
period of a minimum of 5 days to a maximum of 21 
days, while on Sponsor-provided Atrovent HFA 
MDI administered QID and Ventolin HFA for 
rescue use, as needed (PRN) prior to initiating the 
next treatment in their assigned treatment sequence.

Section 4.1 Overall Study Design and Plan
At Visit 4 (Day 1 of TP 2) it is important to ensure 
that the baseline FEV1 is stable and reflective of the
subject’s COPD severity prior to continuing to the 
second treatment period. As such the baseline 
stability criteria will be evaluated (see section 5.1). 
To ensure baseline FEV1 stability at Visit 4 the -
60 minute FEV1 value obtained at Visit 4 will be 
compared to the average predose (-60 and -30 
minute) FEV1
values obtained at Visit 2.  
Revised to provide clarification on 
which  FEV1 values at Visit 4 will 
be used to assess  stability criteria

Section 7.1.1 HRCT Scans
A HRCT scan as baseline measurement will be 
taken on Day 1 of each TP (Visit 2 and Visit 4). 
The pre-dose CT-scan of the thorax will be taken on 
two breathing levels, TLC and FRC. During Visit 2 
an additional scan of the UA will be taken. The 
post-dose measurement will only be performed on 
one breathing level, TLC. The Post dose TLC scan 
will be taken after approximately 2 weeks of 
treatment with either GP MDI or FF MDI on Day 
15 (± 5 days) (Visit 3 and Visit 5)
On Day 1 of each TP (Visit 2 and Visit 4) the CT 
scans will be taken at least 30 minutes prior to 
dosing
Post dose HRCT scan on Day 15 (± 5 days) of each 
TP (Visit 3 and Visit 5) should be started 90min ± 
30 minutes after dosing (approximately between 
1pm-2pm). Spirometry followed by body 
plethysmography will be performed after the HRCT 
scans but within 150 minutes after dosing

Section 7.1.2 Spirometry
At Visit 2 and Visit 4, spirometry will be obtained at 
the beginning of the visit. A second spirometry will 
be obtained before the study drug administration 
after the pre-dose CT-scans are taken. The average 
of the -60 minute FEV1 values value obtained at 
Visit 4 prior to study drug administration will be 
used to check the stability criteria. At Visit 3 and 
Visit 5, spirometry will be obtained before the study 
drug administration, and post-dosing of study drug.
Post-dose spirometry assessments will not be 
conducted before the CT-scan is taken. At Visits 3 
and 5 none of the post dose assessments will start 
before 1 hour after the administration of the study 
drug. All assessments should be completed within 
2.5 hours after dosing

Cross-Over, Multi-Center Study to Evaluate the Effects of PT001 and PT005 on Specific 
Image Based Airway Volumes and Resistance in Subjects With Moderate to Severe COPD. 
Study Number:  PT003019-01  / FLUI-2015-140 
Study Phase: IIIb 
Study Objectives:
Primary Objectives:
x
To assess the effect of treatment with Glycopyronnium (GP) MDI administered twice daily 
(BID) and Formoterol Fumarate (FF) MDI administered BID on specific image-based 
airway volumes and resistance in subjects with moderate to severe chronic obstructive 
pulmonary disease (COPD) following chronic dosing after approximately two weeks 
treatment.
Secondary Objectives:
x
To assess the effects of GP MDI and FF MDI on various Functional Respiratory Imaging 
(FRI) parameters.
x
To assess the effects of GP MDI and FF MDI on lung function parameters.  
Safety Objective:
To assess the safety of GP MDI and FF MDI in subjects with moderate to severe COPD based
on adverse events (AEs), and any clinically relevant findings from vital sign measurements, 
electrocardiograms (ECGs), physical examination findings, and clinical laboratory evaluations.

Study Design:
This is a multi-center, double-blind, two treatment, two period, full cross-over, chronic dosing
(2 weeks) study to assess the effects of GP MDI (14.4 μg BID) and FF MDI (9.6 μg BID) on 
specific image-based airway volumes and resistance in subjects with moderate to severe
COPD.  In this study, airway dimension parameters will be calculated for each of the two 
active compounds. 
This multi-center study will be conducted at a minimum of one site.  Across these sites, it is 
planned that approximately 20 subjects with moderate to severe COPD will be randomized 
into this study.
Study design chart:
Computed Tomography (CT)-scans during study: On Day 1 of each Treatment Period (TP 
[Visit 2 and Visit 4]) baseline measurement inspiratory scan (total lung capacity [TLC] scan) 
and expiratory scan (functional residual capacity [FRC] scan) will be conducted.  During Visit 
2 an additional scan of the upper airway (UA) will be taken. Post dose measurement inspiratory 
scan (total lung capacity [TLC] scan) will be taken after approximately 2 weeks of treatment 
with either GP MDI or FF MDI on Day 15 ± 5 days (Visit 3 and Visit 5). Post dose activities 
should be started 1 hour after dosing on Visit 3 and Visit 5 and should be concluded within 2.5 
hours after dosing. Between the Treatment Periods there will be a washout period of 5-21 days.

Statistical Methods:
All statistical analysis will be conducted using 
  
For the efficacy analyses, the effects of both GP MDI and FF MDI will be assessed. The effect 
is defined as the difference between the value at Day 15 and the value prior to dosing on Day
1. Effect is thus the change from baseline to GP MDI, for GP MDI treatment and as the change 
from baseline to FF MDI, for FF MDI treatment.
For each parameter in each group (primary efficacy endpoints: FRI; secondary efficacy 
endpoints: FRI, spirometry and body plethysmography; other efficacy endpoints: all FRI 
parameters except the mass of deposited particles, spirometry and body plethysmography), this 
effect will be assessed. Additional analyses will compare the distribution of regional effects 
between the two treatments for the different FRI endpoints. A linear mixed model approach 
will be chosen and specified fully in the statistical analysis plan.
The Intent-to-Treat (ITT) Population will be considered the primary analysis population for 
efficacy. Supportive analyses will be conducted with the Modified Intent-to-Treat (mITT) 
Population.

INTRODUCTION AND STUDY RATIONALE
Chronic obstructive pulmonary disease (COPD) is a leading cause of morbidity and mortality at 
a global level and recent statistics suggest it will become more prevalent as smoking frequencies 
rise and the population ages (Calverley, 2003; Feenstra, 2001; Ferrer, 1997; Murray, 1997;
Sullivan, 2000). In a systematic review and meta-analysis by Halbert and colleagues, the 
SUHYDOHQFHRISK\VLRORJLFDOO\GHILQHG&23'LQDGXOWVDJHG\HDUVZDVREVHUYHGWREH-10% 
(Halbert 2003 and Halbert 2006). The causes behind COPD are multifactorial, where various risk 
factors and environmental stimuli have been identified and include smoking, air pollution, and 
occupational hazards. 
COPD is a disease of the lungs characterized by airflow limitation that is not fully reversible. 
The chronic airflow limitation characteristic of COPD is caused by a mixture of small airways 
disease (obstructive bronchiolitis) and parenchymal destruction (emphysema) the relative 
contributions of which vary from person to person. The airflow limitation tends to be progressive 
in nature and is frequently associated with an abnormal inflammatory response of the lung to 
noxious particles or gases. This disease is characterized by premature loss of ventilator function 
as determined by a decline in forced expiratory volume in the first second of exhalation (FEV1). 
Pathological inflammatory changes are characterized by elevations in activated macrophages, 
neutrophils, elastases, and CD8 lymphocytes. These molecular and cellular changes caused the 
destruction of small airways and surrounding alveoli. As expiratory airflow (FEV1 or forced vital 
capacity [FVC]) is a function of pressure against resistance, airflow in COPD is diminished due 
to a loss of elastic recoil and airway constriction.
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 beta2 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 (ICS)/LABA or a LAMA is 
currently recommended (GOLD, 2015).
Pearl Therapeutics, Inc. (hereafter referred to as Pearl) is conducting a study (PT003018) 
comparing a Pearl combination product, Glycopyrronium and Formoterol Fumarate (GFF) 
Inhalation Aerosol (PT003) metered dose inhaler [MDI] versus placebo MDI evaluating 
Functional Respiratory Imaging (FRI) and lung function parameters. In the current study, the 
effect of glycopyrronium (GP) MDI 14.4 μg (PT001) and formoterol fumarate (FF) MDI 9.6 μg 
(PT005) on FRI and lung function parameters will be evaluated individually.
Glycopyrronium is a LAMA which exerts bronchodilator 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.

An inhaled formulation of glycopyrronium (Seebri® Breezhaler®
Inhalation Powder, 
glycopyrronium bromide) was recently approved throughout the European Union (EU), 
Australia, Canada, and Japan for the management of adult subjects with COPD. The 
recommended dose is 44 μg (delivered dose of 55 μg of glycopyrronium bromide equivalent to 
44 μg of glycopyrronium) administered once daily (QD) using the Seebri Breezhaler inhaler. 
Additionally, an inhaled formulation of glycopyrrolate (SeebriTM Neohaler® Inhalation Powder, 
glycopyrronium bromide, 15.6 μg twice daily [BID]) was recently approved in the United States 
for the management of COPD in adult subjects. 
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 
bronchodilator. Formoterol fumarDWH VWLPXODWHV ȕ2 adrenoreceptors in the airways, inducing 
airway smooth muscle relaxation and reducing or preventing bronchoconstriction.
A more detailed description can be obtained in the Investigator Brochure (IB).
1.1 Study Rationale
GP is a potent LAMA which exerts it bronchodilatory effect via muscarinic receptors located on 
smooth muscle cells within the trachea and bronchi.  GP is Pearl's glycopyrronium MDI 
monotherapy product under evaluation to treat patients with COPD. GP has been evaluated in 8 
studies conducted by Pearl.  The lower end of the dose response curve has been adequately 
characterized in two chronic-dose, dose-ranging studies (PT001002 and PT001003), and the 
findings from these two studies and the previous Phase II studies support a dose of GP MDI 14.4 
μg.
FF is a potent and selective LABA approved in many countries worldwide for use in asthma and 
COPD.  Pearl Therapeutics has conducted three studies to confirm dose selection and safety for 
FF MDI. These include studies PT0050801, PT0031002, and PT003005. Results demonstrated 
dose proportionality of FF MDI 9.6 ug and bioequivalence to Foradil with no substantial 
differences in terms of safety between the FF MDI treatment groups to placebo or to Foradil 12 
ug, and there were no important trends noted for FF MDI at any dose.
In this study the effects of treatment with Pearl's monotherapy GP and FF MDIs on specific 
image based airway volumes and resistance in subjects with moderate to severe COPD will be 
assessed. This imaging methodology will allow an assessment of the extent of airway changes 
using the monotherapy products GP and FF. Previous studies demonstrated that looking directly 
at airway volumes and resistance is a more sensitive measure as FEV1 to evaluate the acute 
bronchodilating effect of inhaled LABA and/or LAMA (De Backer, 2011; De Backer, 2012;
Vos, 2013).

4 INVESTIGATIONAL PLAN
4.1 Overall Study Design and Plan
This is a multi-center, chronic dosing (approximately 2 weeks) study to assess the effects of GP 
MDI (14.4 μg BID) and FF MDI (9.6 μg  BID) in subjects with moderate to severe COPD on 
specific image based airway volumes and resistance and lung function.
In this study 20 subjects will be included with moderate to severe COPD. Subjects will be 
randomized in two treatment sequences. Subjects in sequence 1 will receive GP MDI in TP 1
followed by FF MDI in TP 2. Subjects in sequence 2 will receive FF MDI in TP 1 followed by 
GP MDI in TP 2. 
Subjects will receive approximately 2 weeks of study treatment with each of their assigned 
treatments for a total of two separate TPs. A washout period of 5-21 days will occur between 
each TP. The entire study period is scheduled to take approximately 13 weeks for each individual
subject from the time of Screening.  
Prior to or at Visit 1 (Screening), all subjects are to sign an informed consent form prior to the 
conduct of any screening assessments. The Investigator or designee 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 for COPD (30% < FEV1 <80% predicted and FEV1/FVC ratio <0.70) at Visit 
1 to qualify for study enrollment. Reversibility of FEV1 approximately 30-60 minutes following 
four puffs of Ventolin® HFA will be assessed and a ventilation-perfusion relationship 
measurement (diffusion capacity) will be performed at Screening (Visit 1) to characterize the 
subject population. 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. . At Visit 1 (Screening), eligible subjects
who are
using a prohibited COPD medication (refer to Table 5-1) and meet all other entry
criteria will return to the clinic in 7
to 21 days for Visit 2 (Randomization Visit). For more 
details on Visit 1 procedures, refer to Section 8.1.
Subjects who meet all entry criteria but are using certain prohibited COPD medications (eg., oral
ȕ2-agonists, LABAs, LAMAs, LABA/LAMA, corticosteroid/LABA combination products, 
cromoglycate or nedocromil inhalers, leukotriene antagonists [eg., zafirlukast, montelukast] or
tiotropium

and vilanterol), Ultibro® Breezhaler® (indacaterol and glycopyrronium), and Spiolto® Respimat®
(tiotropium and olodaterol) will discontinue these medications for the duration of the study. 
Subjects taking a fixed-dose combination treatment with an ICS plus a LABA must discontinue

the combined medication and instead be prescribed an ICS monotherapy at an equivalent dose 
and regimen for the duration of the study. Subjects previously using an ICS and/or 
phosphodiesterase inhibitor may continue using the medications at the same dose as previously 
described. During the Run-in period, and between Visits 3 and 4, subjects will use 
Sponsor-provided Atrovent® HFA [Atrovent, 2012], administered four times daily (QID) (see
Section 6.7.2) and sponsor-provided rescue Ventolin® HFA (albuterol sulfate inhalation aerosol) 
(GlaxoSmithKline), as needed (PRN), to control symptoms (see Section 6.7.3).
At Visit 1 several key assessments (refer to Table 8-11) shall be obtained. Additionally, dyspnea 
will be evaluated with the Modified Medical Research Council (MMRC) questionnaire, and the 
burden of disease will be assessed through the COPD Assessment Test (CAT), therefore, it is 
necessary for all subjects to be appropriately washed out of their inhaled COPD medications 
prior to Visit 1 (refer to Section 5.4.1). 
At Visit 2 (Randomization Visit; Day 1 of TP 1), subjects will return to the clinic. Site staff must 
confirm the subject meets all protocol-specific requirements and ensure adequate washout 
(6 hours or longer) of all inhaled medications (including ICS, and rescue medication), except for 
sponsor-provided Atrovent® HFA. Subjects who continue to meet entry inclusion/exclusion 
criteria and remain eligible for participation in the study will be randomized into one of two 
pre-defined treatment sequences (possible treatment sequences to which a subject can be 
randomized are shown in Section 9.4). All subjects ZLOOUHFHLYH*30',ȝJ%,'GXULQJ

Period of a minimum of 5 days to a maximum of 21 days between each TP. 
At Visit 2 subjects will complete all pre-dose timed assessments and in the beginning of the visit 
the baseline FEV1 value will be obtained, refer to Table 8-12 prior to receiving their first dose of 
GFF MDI or Placebo MDI in the clinic under site personnel supervision. During the pre-dose 
assessements ascan of the upper airway (UA) will be taken. After the CT-scans are taken, 
spirometry and body plethysmography will be performed; the inhalation profile will be measured 
with the body plethysmograph and respiration belts. The subject's inhalation profile will be 
measured in order to draw an airflow versus time curve. At the moment of this measurement the 
signal from the respiration belt, used for the measurement of the inhalation profile during the 
study drug administration, will also be logged.
Prior to MDI administration on Day 1 of TP 1 and 2, the MDI device will be primed (four 
actuations to waste) at the study site by the study team in a room separated from the patient. 
After administration of the subject’s first dose, all post-dose assessments will be performed, refer 
to Table 8-12. Following completion of all assessments, subjects will be discharged from the
clinic and will be instructed to continue to administer TP 1 study drug for approximately 2 weeks 
at home until Visit 3.
For more details on Visit 2 procedures, refer to Section
8.2.
The subject, clinical site personnel, and Pearl will be unaware of the treatment sequence assigned 
to a subject; it will not be possible to differentiate between GP and FF MDIs since they will be
identical in all aspects. The GP and FF MDIs will be administered BID.

Subjects will be trained on how to read the dose indicator. See Section 7.1.9 and Appendix 6 for 
instructions on how and when to read the dose indicator.
On Visit 3 (Day 15 ± 5 of TP 1) subjects will perform a spirometry test and will undergo Visit 3 
protocol-defined pre-dose assessments (refer to Table 8-11 and Table 8-13). The site personnel 
will wait 1 hour after the administration of study drug before initiating post-dose assessments. 
Post-dose assessments need to be completed within 2.5 hours after dosing the subject. Study drug 
will be collected. Prior to discharge from the study clinic, subjects will be instructed to undergo a
study drug washout period of a minimum of 5 days to a maximum of 21 days, while on 
Sponsor-provided Atrovent HFA MDI administered QID and Ventolin HFA for rescue use, as 
needed (PRN) prior to initiating the next treatment in their assigned treatment sequence. For 
more details on Visit 3 procedures, refer to Section 8.3 and Table 8-13.
At Visit 4 (Day 1 of TP 2) it is important to ensure that the baseline FEV1 is stable and reflective 
of the subject’s COPD severity prior to continuating to the second TP. As such baseline stability 
criteria will be evaluated (see Section 5.1). To ensure baseline FEV1 stability at Visit 4 the -60
minute FEV1 value obtained at Visit 4 will be compared to the average of the pre-dose (-60 and -
30 minute) FEV1 values obtained at Visit 2.  Subjects meeting baseline stability criteria will be 
dispensed TP 2 study drug according to their assigned treatment sequence and will administer 
their first dose in the clinic under site personnel supervision. Subjects will undergo all
protocol-defined assessments (see Table 8-11 and Table 8-12), will be discharged from the 
clinic, and will be instructed to continue study drug administration for approximately 2 weeks 
(14 days ±5 days) until Visit 5. For more details on Visit 4 procedures, refer to Section 8.4 and 
Table 8-11.
At Visit 5 (Day 15 ± 5 of TP 2) subjects will again return to the clinic for administration of the 
final dose of TP 2 study drug under site personnel supervision. Visit 5 will serve as the final 
clinic visit.  Prior to the administration of the final dose of study drug subjects will perform a 
spirometry test and will undergo Visit 5 protocol-defined pre-dose assessments
(see 
Table 8-11 and Table 8-13).  The site personnel will wait 1 hour after the administration of study 
drug before initiating post-dose assessments. Post-dose assessments need to be completed within 
2.5 hours after dosing the subject. Study drug will be collected, subjects returned to pre-study or 
appropriate maintenance COPD medications, and subjects will be discharged from the study. A
telephone follow-up will be performed within 7 to 10 days following Visit 5. For more details on 
Visit 5 procedures, refer to Section 8.5 and Table 8-13.
Refer to Table 8-11 for the overview of the study procedures and assessments to be performed at 
the study visits. 
4.1.1
General Considerations for Treatment Visit 2 through Visit 5 (in-clinic)
•
At the start of each treatment period (Visit 2 and Visit 4), prior to any study procedures being 
performed, site personnel must confirm the subject withheld all inhaled COPD medications 
(including ICS and rescue medication, eg, Ventolin HFA, except sponsor-provided Atrovent®
HFA for at least 6 hours, by confirming the last time of dosing for all COPD medication(s).

Note:
Subjects who inadvertently took COPD medication(s) (except for sponsor-
provided Atrovent® HFA) within 6 hours of the start of study procedures must be 
rescheduled as soon as is practical but within the specified visit window.
Note: Before the in-clinic dose is administered, the site must confirm the subject meets 
all other protocol-specified requirements.
Note:
Subjects must administer sponsor-provided Atrovent® HFA the morning of Visit 
2 and Visit 4 5-6 hours prior to the anticipated time of the post-dose CT scan.
•
At the end of each treatment period (Visit 3 and Visit 5), prior to any study procedures being 
performed, site personnel must confirm the subject withheld all inhaled COPD medications 
(including randomized study medication, ICS and rescue medication, eg., Ventolin HFA) for at
least 6 hours, by confirming the last time of dosing for all COPD medication(s). 
Note: Subjects who inadvertently took inhaled COPD medication(s) within 6 hours of 
the start of study procedures must be rescheduled as soon as is practical but within the 
specified visit window.
Note: Before the in-clinic dose is administered, the site must confirm the subject meets 
all other protocol-specified requirements.
•
Subjects must not ingest xanthine-containing foods and beverages for at least 6 hours prior to 
each study visit and for the duration of each study visit (see Section 5.5.2). 
•
Subjects will be required to refrain from smoking (nicotine gums and patches are allowed) 
for at least 4 hours prior to each study visit and throughout the duration of each study visit.
•
To ensure standardization of dosing times, it is recommended that the sites encourage 
subjects to maintain a dosing schedule at home consistent with their in-clinic dosing time.
Subjects will be required to take their study drug BID in the morning between 07:00 and 
11:00 am (breakfast time) and in the evening between 07:00 and 11:00 pm (dinner time).
•
In order to minimize diurnal variance, site should discuss the importance with the subject of 
dosing in a timely manner every 12 hours for blinded study medication.
•
In order to minimize diurnal variance, site should make every effort to assess subjects at the 
same time throughout the study.
Subjects will be required to return to the clinic at approximately the same time for all 
treatment visits and will be required to remain at the clinic until completion of all 
protocol-defined assessments.
•
The site should make every effort to ensure that the in-clinic dosing time for BID treatment
occurs around 11:00 am and within 12±2 hours of the prior at-home evening dosing time. Site

To bring their study drugs, sponsor-provided Atrovent® HFA and sponsor-provided 
Ventolin® HFA with them to the clinic. 
To administer sponsor-provided Atrovent® HFA the morning of Visit 2 and Visit 4 5-6
hours prior to the anticipated time of the post-dose CT scan.
To withhold all inhaled COPD medications (including randomized study medication, 
ICS, and rescue medication) for at least 6 hours prior to study assessments with the 
exception of sponsor-provided Atrovent® HFA at Visit 2 and Visit 4. 
To refrain from ingesting xanthine-containing foods and beverages for at least 6 hours 
prior to each study visit and for the duration of each study visit.
To refrain from smoking for at least 4 hours prior to the study visit and throughout the 
duration of each study visit.
•
The in-clinic dosing time will be recorded as the time of administration of the second puff of 
study drug.
•
Site personnel will instruct subjects not to take any non-study COPD medications, without 
site personnel permission, during a visit until all study procedures have been completed and 
the subject is discharged from the clinic. Site personnel should take every precaution to 
prevent use of non-study inhaled COPD medications during a test day. Site personnel may 
request the subject to surrender all non-study COPD medications prior to the start of the visit 
before performing any study procedures and return the medications to the subject at the end 
of the visit when all study procedures are completed if the Investigator is of the opinion this 
is needed.
•
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 for 
use in the subject’s worksheet and all subsequent spirometry assessments should be stopped. 
However, safety assessments should be continued at the discretion of the Investigator.
•
Every effort must be made to ensure that subjects return to the clinic on Day 15 following the
initiation of each treatment period. To accommodate scheduling conflicts, a window of Day 15 ± 
5 days is permitted (i.e., Day 15 procedures must be done within a minimum of 10 days and a 
maximum of 20 days from Day 1).
During each TP (Visits 2 to 3, and Visits 4 to 5), subjects will be permitted to use 
Sponsor-provided Ventolin HFA on an as-needed basis for relief of COPD symptoms.
During the run-in period and washout period, when subjects are not taking study drug (Visits 1 to 
2, and Visits 3 to 4), subjects will use the Sponsor-provided short-acting bronchodilator
(Atrovent HFA) administered QID and may use Ventolin HFA on an as- needed basis.
Protocol-adjusted ICS therapy defined at Screening, if any, should be continued and remain 
stable for the duration of the study (see Section 5.4 for further guidance related to 
phosphodiesterase inhibitors).

4.2 Rationale of Study Design
This study will assess the effects of GP MDI 14.4 μg administered BID and FF MDI 9.6 μg 
administered BID on specific image based airway volumes and resistance.
A randomized, double-blind, full cross-over design was adopted in order to increase the 
precision of comparisons between treatment groups.
4.3 Rationale of Dose/Regimen, Duration of Treatment
The selection of the GP MDI (14.4 ȝg BID) and FF MDI (9.6 ȝg BID) dose in this study was 
based on data from the findings of three previous dose-ranging studies with GP MDI
(Studies PT0010801, PT001002, and PT001003), two dose-ranging clinical studies with FF MDI 
(Studies PT0050801 and PT005003), and four studies with GFF MDI (Studies PT0031002, 
PT003003, PT003004, and PT003005). 
These programs identified the optimal doses as 9.6 ȝg BID for FF MDI and 14.4 ȝg BID for GP 
MDI. The aforementioned studies also showed that Glycopyrronium 14.4 μg when added to 
formoterol fumarate 9.6 μg provides a reasonable benefit across all parameters.  GFF MDI 
14.4/9.6 μg was safe and well- tolerated with an AE profile similar to its components and other 
approved products for the management of COPD (ie, Spiriva, Atrovent, and Foradil®
Aerolizer®).
The study will evaluate the individual effects of GP MDI and FF MDI on specific image based 
airway volumes and resistance, other various FRI parameters, and lung function tests 
over 2 weeks.

•
During the TP 1 and 2 (Visit 2 to Visit 3 and Visit 4 to Visit 5), subjects treated with oral 
corticosteroids and/ or antibiotics for exacerbation should be discontinued from the study.
Subjects who meet all entry criteria but are using one or more of the prohibited COPD 
medications (previously listed) will have their maintenance therapy for COPD adjusted as 
follows: 
•
Subjects taking prohibited inhaled COPD medications (listed previously) will discontinue 
these medications 6 hours to 24 hours before Visit 1 for the duration of the trial after 
informed consent is obtained. At Visit 1 subjects will be switched to sponsor-provided 
Atrovent HFA MDI administered QID (during the run-in and wash-out periods only) and 
sponsor-provided Ventolin HFA to be administered as needed (PRN) throughout the study 
for control of COPD symptoms.
•
Subjects receiving a maintenance dose of an ICS as part of a fixed dose combination therapy
containing fluticasone and salmeterol, mometasone and formoterol, budesonide and 
formoterol or fluticasone and formoterol must have been on the ICS component for at least 
4 weeks prior to Visit 1 (Screening) and maintained on a stable dose for at least 4 weeks prior 
to Visit 1 (Screening). At Visit 1 these subjects will be switched to the corresponding dose of
fluticasone, mometasone or budesonide administered as a single agent BID and may continue 
the ICS during the study, sponsor-provided Atrovent HFA MDI administered QID (during 
the run-in and wash-out periods only), and sponsor-provided Ventolin HFA to be 
administered as needed (PRN) throughout the study for control of COPD symptoms.
•
Subjects receiving a maintenance dose of an ICS that is not administered as a fixed-dose 
combination together with a LABA will be permitted to continue the ICS provided they have
been maintained on a stable dose for at least 4 weeks prior to Visit 1 (Screening). In this case 
subjects will be asked to withhold ICS 6 hours before every study visit.
•
All subjects treated with either a LABA (salmeterol, formoterol, indacaterol) or currently 
marketed LAMA (tiotropium, aclidinium, glycopyrronium, [eg, Seebri]) administered alone

5.5 Other Restrictions, Illicit Drugs or Drugs of Abuse
5.5.1
Illicit Drugs and/or Drugs of Abuse
Illicit drugs or drugs of abuse will not be allowed from the start of Screening (Visit 1) to the end 
of Visit 5 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.  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 are encouraged to refrain from consuming grapefruits or grapefruit juice throughout the 
study. Subjects must not ingest xanthine (ie, 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 (ie, 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 (ie, whether a subject’s status has changed from smoker to non-smoker or 
vice versa). Any change in smoking status during the run-in period (Visit 1 to Visit 2) will result 
in a screen failure. Smoking status changes during the 2 week TPs will be captured in the eCRF, 
but the subject will be permitted to continue in the study. Subjects will be required to refrain 
from smoking (including medical marijuana and electronic cigarettes) for at least 4 hours prior to 
each study visit 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-years to determine cigarette smoking 
history.
5.7 Reasons and Procedures for Early Termination
Subjects may be withdrawn from the study at any time at their own request, at the request of the 
Investigator, or by Pearl at any time or for any reason. 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 being randomized, regardless of the cause, should undergo the 
assessments outlined in Section 8.6 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:
•
Following dosing, a heart rate increase of greater than 40 bpm from the pre-dose value 
obtained on Day 1 of Treatment Period 1 (Visit 2) and Treatment Period 2 (Visit 4) and the 
measured value is also >120 bpm.
•
Following dosing, a systolic blood pressure (SBP) increase of more than 40 mmHg from the 
pre-dose value obtained on Day 1 of Treatment Period 1 (Visit 2) and Treatment Period 2 
(Visit 4) and the measured value is also >160 mmHg.
•
Decrease in creatinine clearance to a value below 30 ml/minute/1.73m2 using CKD-EPI
equation or a clinically relevant change from baseline as determined by the Investigator.

•
Subjects who suffer a mild exacerbation will remain in the study and continue to take their 
assigned study drug unless the Investigator decides that it is in the best interest of the subject 
to discontinue early from the study. Any subject who suffers a moderate or severe 
exacerbation will be discontinued.  
An exacerbation will be defined as a change in the subject’s baseline dyspnea, cough, and/or 
sputum (increase in volume or change in color towards purulence) that lasts 3 or more days, is 
beyond normal day-to-day variations, is acute in onset and may warrant a change in regular 
medication. The severity of 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 requires treatment with systemic steroids and/or antibiotics, and 
do not result in hospitalization or death.
•
Severe: exacerbations that result in hospitalization or death.
If a subject requires the following prohibited medications they should be discontinued from the 
study:
•
Initiation of maintenance therapy with any prohibited medications as listed in
Table 5-6.
•
Initiation of maintenance therapy with a marketed LABA (eg, salmeterol, formoterol, 
indacaterol) administered alone or in combination with an ICS or a marketed LAMA
(eg, tiotropium, aclidinium, or glycopyrronium bromide [Seebri]).
•
Initiation of corticosteroids/antibiotics for the treatment of exacerbation 
If a female subject becomes pregnant during the course of the study, the subject will be 
discontinued and the pregnancy will be followed full-term through delivery or final outcome 
(refer to Section 7.3.9).

6.5 Emergency Unblinding of Treatment Assignment
The individual subject emergency code break sealed envelopes should be used in order to 
unblind subjects and to unmask drug identity. When the Investigator needs to unblind a subject, 
he/she must confirm the necessity to unblind the subject. The Investigator or treating physician 
may unblind a subject’s treatment assignment only in the case of an emergency, when 
knowledge of the study treatment is essential for the appropriate clinical management or welfare 
of the subject. Whenever possible, the Investigator must first discuss options with the Sponsor 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: Store below 25° C (77° F) in a dry place. Excursions permitted up to 30° C (86°
F).
Ventolin HFA supplies: Store between 15° and 25°C (59° and 77°F). Store the inhaler with the 
mouthpiece down. For best results, the inhaler should be at room temperature before use.   Do 
not use or store near heat or open flame. Exposure to temperatures above 120 °F (49 °C) may 
cause bursting. Never throw into a fire or incinerator.
Atrovent HFA supplies: Store at 25°C (77°F); excursions permitted to 15°-30°C (59°-86°F). 
For optimal results, the canister should be at room temperature before use.  Do not puncture. Do 
not use or store near heat or open flame. Exposure to temperatures above 120°F may cause 
bursting. Never throw the inhaler into a fire or incinerator. 
The clinical supplies storage area at the site must be monitored by the site staff for temperature 
consistency with the acceptable storage temperature range specified in this protocol or in the 
product label. Documentation of temperature monitoring should be maintained.
6.7 Instructions for Preparation of Treatments for Administration and 
Dispensing
6.7.1
GP MDI and FF MDI
Individual GP MDI and FF MDI will be packaged in a foil pouch and contained in an individual 
visit treatment box. Both the visit treatment box and the foil overwrap will have a label with a 
component identification number. Confirm that the identifier given by the randomization lists 
and the component identification number written on the label are the same. The visit treatment 
box is labeled with a two-part label. Write the subject number and treatment visit number on 
each of the two-part labels. The ‘tear-off’ part of the label is to be placed onto the subjects 
worksheets.

All MDIs must be primed before the first use. Priming involves releasing 4 sprays into the air 
before the first use of the inhaler. Shaking and priming the inhaler fills a chamber inside the 
canister with the correct dose and mix of medication so that the inhaler is ready to use.
The MDI must be primed in a separate room from the subject treatment area.  Each dose will 
consist of 2 puffs from the MDI. Subjects will be dispensed the MDI and instructed to continue 
taking study medication twice daily, 2 puffs in the morning and 2 puffs in the evening 
approximately 12 hours apart, until subject returns to the clinic. The MDI should be stored 
upright at room temperature by the subject, avoiding temperature extremes, and storage in direct 
sunlight. Refer to Appendix 1 for instructions on the administration of GP MDI and FF MDI.  
Cleaning instructions are provided in Appendix 1.
6.7.2
Atrovent HFA (Ipratropium Bromide) 
Open-label Atrovent HFA will be provided by Pearl and stored in a secured location within the 
clinic or pharmacy facilities.  
Atrovent HFA is a solution aerosol that does not require shaking. However, as with any other 
MDI, some coordination is required between actuating the canister and inhaling the medication. 
Atrovent HFA should be primed per manufacturer’s instructions prior to dispensing to subject 
(ie, "prime" or actuate Atrovent HFA before using for the first time by releasing 2 test sprays 
into the air away from the face). In cases where the inhaler has not been used for more than 3 
days, prime the inhaler again by releasing 2 test sprays into the air away from the face. Subjects 
should avoid spraying Atrovent HFA into their eyes.
Subjects will be dispensed the Atrovent HFA for COPD maintenance therapy during the run-in 
period (between Visit 1 and 2) and during the washout period (between Visit 3 and 4) per the 
manufacturer’s instruction, 2 puffs with each administration four times a day, divided over the 
daytime. The MDI should be stored at room temperature by the subject, avoiding temperature 
extremes and storage in direct sunlight. Refer to Appendix 2 for the manufacturer’s instructions 
on the administration of Atrovent HFA.
6.7.3
Ventolin HFA (Albuterol Sulfate)
Open-label Ventolin HFA will be provided by Pearl and stored in a secured location within the 
clinic or pharmacy facilities. Ventolin HFA should be stored at room temperature by the subject. 
Ventolin HFA should be primed per manufacturer’s instructions prior to dispensing to subject. 
Refer to Appendix 3 for the manufacturer’s instructions on the administration of Ventolin HFA. 
Study personnel will record number on the dose counter at the time of dispensing (following 
priming and characterization of reversibility) and upon return. 
6.8 Drug Accountability/Return of Clinical Supplies
Under no circumstances will the Investigator(s) allow the study drug to be used other than 
as directed by this protocol.
Investigational clinical supplies must be received by a designated person at the study site, 
handled and stored safely and properly, and kept in a secure location to which only the

Investigator and designated assistants have access. Storage conditions for the clinical supplies 
should be observed, monitored and documented. Clinical supplies are to be dispensed only in 
accordance with the protocol. The Investigator 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. 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 each site’s investigator file. Pearl will contact the site to 
evaluate the nature of the complaint and determine what further action is needed.

STUDY PROCEDURES
The ICF must be obtained prior to performing any and all study-related activities. The ICF must 
be approved by the Independent Ethics Committee (IEC)/ Institutional Review Board (IRB) 
that is reviewing the study documents. Informed consent will be obtained for all subjects 
participating in the study. Subjects may withdraw consent at any time. Participation in the study
may be terminated at any time without the subject’s consent at the discretion of the Principal
Investigator.
A schedule of events is provided in Table 8-11. Detailed schedules for pre and post-dose 
procedures to be performed on visit days are provided in Table 8-12 and Table 8-13.
7.1
Efficacy Assessments
7.1.1
HRCT scans
A HRCT scan as baseline measurement will be taken on Day 1 of each TP (Visit 2 and Visit 4). 
The pre-dose CT-scan of the thorax will be taken on two breathing levels, TLC and FRC. During 
Visit 2 an additional scan of the UA will be taken. The post-dose measurement will only be 
performed on one breathing level, TLC. The Post dose TLC scan will be taken after 
approximately 2 weeks of treatment with either GP MDI or FF MDI on Day 15 (± 5 days) (Visit 
3 and Visit 5). 
On Day 1 of each TP (Visit 2 and Visit 4) the CT scans will be taken at least 30 minutes prior to 
dosing.
Post dose HRCT scan on Day 15 (± 5 days) of each TP (Visit 3 and Visit 5) should be started 
90min ± 30 minutes after dosing (approximately between 1pm-2pm). Spirometry followed by 
body plethysmography will be performed after the HRCT scans but within 150 minutes after 
dosing.
Between the two TPs there will be a washout period of a minimum of 5 days up to a maximum 
of 21 days.
Whenever possible the same scanner should be used at all the study visits.
HRCT scan is performed with a low radiation protocol. These images are made to perform 
Computational fluid dynamics (CFD) in order to obtain more information on regional lung 
function characteristics. For more details of the protocol of CT scan and CFD please refer to the 
addendum in Appendix 7.

7.1.2
Spirometry
Forced expiratory spirometry maneuvers for derivation of FEV1, FVC, FEF25-75, FEV1/FVC ratio 
and IC will be assessed using a spirometer that meets or exceeds minimum performance 
recommendations of the ATS.
Spirometry will be conducted at all visits. At Visit 1, Spirometry will be conducted
approximately 60 minutes and 30 minutes prior to bronchodilator administration and 
approximately 30-60 minutes post-bronchodilator (refer to Section 7.1.2.1). 
Note: Spirometry must meet the severity and both acceptability and repeatability criteria (refer to 
Section 5.1 and Section 5.2).
At Visit 2 and Visit 4, spirometry will be obtained at the beginning of the visit. A second 
spirometry will be obtained before the study drug administration after the pre-dose CT-scans are 
taken. The -60 minute FEV1 value obtained at Visit 4 prior to study drug administration will be 
used to check the stability criteria. At Visit 3 and Visit 5, spirometry will be obtained before the 
study drug administration, and post-dosing of study drug. Post-dose spirometry assessments will 
not be conducted before the CT-scan is taken At Visit 3 and 5 none of the post dose assessments 
will start before 1 hour after the administration of the study drug. All assessments should be 
completed within 2.5 hours after dosing.
7.1.2.1
Characterization of Reversibility
Reversibility to Ventolin HFA (SABA) will be evaluated at Visit 1.  
The procedure will be, as follows:  Reversibility testing to Ventolin HFA:
x
Perform pre-bronchodilator PFTs (approximately -60 minutes and -30 minutes) prior to 
administration of Ventolin HFA (albuterol).
x
Administer 4 puffs of Ventolin HFA (albuterol).
x
Perform post-bronchodilator PFT 30-60 minutes after the administration of Ventolin HFA.
Reversibility will be a comparison of the average best FEV1 effort obtained at approximately 
-60 minutes and -30 minutes pre-bronchodilator to the best FEV1
effort obtained at 
approximately 30-60 minutes post-bronchodilator. A subject is determined to be reversible to 
Ventolin HFA if the improvement in FEV1
approximately 30-60 minutes following 
administration of 4 SXIIVRI9HQWROLQ+)$UHVSHFWLYHO\LVDQG ml. Reversibility to 
Ventolin HFA (obtained at Visit 1) will be used to characterize the population.
7.1.2.2
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 TP.
At Visit 2, spirometry will be obtained at the beginning of the visit. A second spirometry will be 
obtained before the study drug administration after the pre-dose CT scans are taken. The average

of the FEV1 values obtained prior to study drug administration (- 60 min and - 30 min) at Visit 2 
will be the baseline value used to compare with the -60 minute FEV1 value obtained at Visit 4. 
At Visit 4, if the pre-dose FEV1 is outside of the ±20% or 200 mL range compared to the average 
(-30 and -60 minute) pre-dose FEV1 value of Visit 2, at the investigator's discretion, the visit 
may be rescheduled or the subject may be discontinued.
7.1.2.3
Inspiratory Capacity
Visit 1 to Visit 5: IC assessments will be conducted with every spirometry. 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 TLC with no hesitation. From at least three acceptable trials, 
the two largest IC measurements should agree within 5% or 150 ml, both of these IC values will 
be captured and analyzed. 
7.1.2.4
Standardization of IC and Spirometry Collections
All pulmonary function tests including FEV1, FVC, FEF25-75, FEV1/FVC ratio, as well as all IC 
assessments, as defined in ATS/ERS guidelines will be performed in accordance with ATS 
criteria (Miller, 2005).
The volume accuracy of the spirometer is to be checked daily using a 3 L syringe across 3 flow 
ranges (ie, low, medium and high flows), with temperature and barometric pressure correction. 
The calibration syringe must meet ATS specifications and must not be used beyond the expiry 
date. Required accuracy is ± 3% (i.e, 3,09 L to 2,91 L) (ATS/ERS).  The results of the calibration 
factor will be maintained on site, which will be available if the sponsor wants to check for 
compliance or an audit.
7.1.3
Body plethysmography
Visit 2 to Visit 5: RV, TLC, FRC, Raw,
sRaw,
sGaw will be measured using body 
plethysmography.
On Day 1 of each TP (Visit 2 and Visit 4) the body plethysmography measurement will be 
performed after the CT-scan before the IP administration.
On Day 15 (± 5 days) of each TP (Visit 3 and Visit 5) the body plethysmography measurement 
will be performed after the CT-scan and after the post-dose spirometry measurement.
Post dose activities on Day 15 (± 5 days)  of each TP (Visit 3 and Visit 5) will be started 1 hour 
after dosing on and will be concluded within 2.5 hours after dosing. 
7.1.4
Diffusion capacity
The single-breath diffusing capacity of the lungs for carbon monoxide (TCO), alveolar volume 
(VA) and TCO/VA will be measured at Visit 1. TCO measurement will be used to characterize

the subjects enrolled in the trial and will not be used to determine subject eligibility to participate 
in the study. 
7.1.5
Inhalation Profile with Body Plethysmography
Visit 2 and Visit 4: In order to draw an airflow versus time curve, the subject’s inhalation profile 
will be measured. The subject will be asked to inhale and exhale maximally through a 
mouthpiece without a nose clip. This measurement is performed with a body plethysmograph. At 
the moment of this measurement the signal from the respiration belt, used for the measurement 
of the inhalation profile during the study drug administration, will also be logged. 
7.1.6
Inhalation Profile during administration
Visit 2 and Visit 4: During IP administration on Day 1 of both active compounds, the inhalation 
profile will be recorded while the subject inhales through the device to generate a subject 
specific inhalation profile by using a respiration belt. The thorax and abdomen expansion will be 
measured with the 
 diagnostic device. This inhalation profile which represents the lung 
expansion during inhalation of the medication can be coupled with the values of the 
corresponding lung volume expansion (RV – TLC) measured with the body plethysmography 
wearing the respiration belts. 
Sensor cables transmit the appropriate signals to the 
. The signals are stored on the 
removable memory card, or if configured to do so, the signals can be displayed from the 
 
 on a computer running the 
 software application.  
7.1.7
Subject Diary Data Collection
At Visit 1, subjects will be provided with a Diary to be completed twice daily (morning and 
evening).  Study personnel will train subjects on Diary completion and will instruct subjects to 
return Diary responses to the clinic for all in-clinic study visits.  
•
At Visit 1, subjects will be instructed to record in the Diary Atrovent HFA four time daily 
use and rescue Ventolin HFA use during the Run-in Period prior to Visit 2.   
•
At Visit 2, subjects will be instructed to record in the Diary study medication administration 
and the use of rescue Ventolin HFA. 
•
At Visit 3, subjects will be instructed to record in the Diary Atrovent HFA four time daily 
use and rescue Ventolin HFA) use during the Wash-out Period between Visit 3 and Visit 4.   
•
At Visit 4, subjects will be instructed to record in the Diary study medication administration 
and the use of rescue Ventolin HFA.  
Diary Compliance Requirement: Subject participation may be terminated at any time during the 
study for the following reason: 
Chronic failure, in the judgment of the Investigator, to comply with diary completion, despite 
documentation at the site of repeated efforts to reinforce compliance. As defined for this study,

compliance requires >70% subject completion of diary assessments.  The Sponsor may also 
instruct a site to discontinue a subject based on consistent noncompliance.
Subjects who are unable to meet the compliance requirement (>70% subject completion of diary 
assessments) in the last 7 days preceding the Randomization Visit (Visit 2) must be retrained. 
When retraining is required due to non compliance the Randomization Visit (Visit 2) must be 
rescheduled.
In-clinic dosing times and dose indicator readings will be documented in the eCRF by the site 
staff and will not be entered by the subject into their Diary.
During the treatment periods, each subject will record his/her symptoms in the study-provided 
Diary, twice daily (morning and evening).  The subject will record his/her use of rescue Ventolin 
HFA twice daily, morning and evening.  In addition, the subject will record study medication 
usage.
7.1.8
Rescue Ventolin HFA Use 
Subjects requiring more than 8 puffs per day on 3 consecutive days with worsening symptoms 
should contact the site. The number of “puffs” of rescue Ventolin HFA is the number of 
actuations of the canister. For example, when rescue Ventolin HFA is required and 2 actuations 
are inhaled, this should be counted as 2 “puffs.” In the event the subject requires 4 actuations, 
this should be counted as 4 “puffs”.  
At Visit 2 to 5 the subject will be asked to bring the rescue Ventolin HFA and the site personnel 
will record the number of actuations of the canister.
7.1.9
Recording of Dose Indicator Reading
The GP MDI and FF MDI are fitted with a dose indicator to track use of the MDI.
Site personnel will be instructed to record the dose indicator reading from the MDI after priming 
(prior to the first dosing Day 1) and after the first dosing Day 1 of both the TPs (Visit 2 and Visit 
4). All MDIs must be primed before the first use. Priming involves releasing a certain number of 
sprays (4) into the air before the first use of the inhaler.  Shaking and priming the inhaler fills a 
chamber inside the canister with the correct dose and mix of medication so that the inhaler is 
ready to use (For more details refer to Section 6.7).
Prior to dosing at Day 15 (± 5 days)  of each TP Visit (Visit 3 and Visit 4) or at a Premature 
Discontinuation Visit, site personnel will observe the dose indicator reading on the study drug 
returned by the subject and record the dose indicator reading in the source. 
Note: The dose indicator reading recorded by the site staff on Day 15 (± 5 days) of each TP 
(Visit 3 and Visit 5) will be the dose indicator reading observed prior to subject dosing.  
At Visit 3 and 5, the site staff will compare the dose indicator reading from the prior entered 
reading of Day 1 of that TP. For major discrepancies (ie, >20 puff difference), the site staff will

review the major discrepancy with the subject and document reason for the major discrepancy in 
the appropriate study source and eCRF. If appropriate, site staff will retrain the subject on the 
proper use of the MDI.
7.1.10
Subject Questionnaires
The following subject questionnaires will be completed by subjects using the study supplied 
questionnaire at Visit 1: CAT, and MMRC.
7.1.10.1 COPD Assessment Test
The CAT is a self-administered questionnaire designed to assess the condition of subjects and 
overall impact of COPD. 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 MMRC Dyspnea Scale.
Subjects will complete the CAT (refer to Appendix 4) at Visit 1. 
The CAT score will describe the burden and symptomatic impact of COPD in subjects enrolled 
in the trial and will not be used to determine subject eligibility to participate in the study.
7.1.10.2 Modified Medical Research Council Dyspnea Scale
The MMRC Dyspnea Scale uses a simple grading system to assess a subject's level of dyspnea,
shortness of breath (Table 7-9 and Appendix 5).
Table 7-7:
MMRC Dyspnea Scale
Grade
Description of Breathlessness
0
I only get breathless with strenuous exercise.
1
I get short of breath when hurrying on level ground or walking up a slight hill.
2
On level ground, I walk slower than people of the same age because of breathlessness, or have to stop for 
breath when walking at my own pace.
3
I stop for breath after walking about 100 meters or after a few minutes on level ground.
4
I am too breathless to leave the house or I am breathless when dressing.
The MMRC scale is a five-point scale published in 1959 that considers certain activities, such as 
walking or climbing stairs, which provoke breathlessness (Fletcher 1959). In one minute, the 
subject selects a grade on the MMRC scale that most closely matches his/her severity of 
dyspnea. The MMRC scale is considered a discriminative instrument that can categorize subjects 
with COPD in terms of their disability. The MMRC scale is not satisfactory as an evaluative
instrument to measure changes in dyspnea, and its broad grades are generally unresponsive to 
interventions such as pharmacotherapy. 
Subjects will complete the MMRC scale at Visit 1, as a description of the symptomatic burden in 
study subjects. The MMRC scale will not be used to determine subject eligibility to participate in 
the study.

7.1.11
COPD Exacerbations
Site personnel will evaluate whether the subject has experienced a worsening of their COPD that 
meets the definition of a COPD exacerbation since their last visit. An exacerbation will be 
defined as a change in the subject’s baseline dyspnea, cough, and/or sputum (increase in volume 
or change in color towards purulence) that lasts 3 or more days, is beyond normal day-to-day 
variations, is acute in onset and may warrant a change in regular medication.
All COPD exacerbations will be reported as AEs unless considered a serious adverse event 
(SAE).
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.
7.2 Safety Assessments
The safety assessments include physical examination findings, vital signs, ECGs, clinical 
laboratory tests in addition to recording of AEs and SAEs. 
7.2.1
Medical/Surgical History and Physical Examination
Medical history, including smoking history details, will be collected at Visit 1 (Screening) and 
updated during the run-in period (Visit 1 to Visit 2). The number of COPD exacerbations 
requiring oral steroids and/or oral antibiotics, or hospitalization within 12 months of Visit 1 
(Screening) will be collected. A complete physical examination will be performed at Visit 1 
(Screening) and at Visit 5. A complete physical examination will include evaluation of relevant 
body parts, general appearance, skin, head, eyes, ears, nose, throat, neck (including thyroid), 
lymph nodes, chest, heart, abdomen, extremities, and nervous system. Weight, assessed in 
ordinary indoor clothing with shoes removed and height will be recorded at Visit 1 (Screening).
At all visits (including the follow-up telephone call [TC]) the subject will be asked about any 
recent change in their smoking status (ie, whether a subject’s status has changed from smoker to 
non-smoker or vice versa).  
7.2.2
Vital Sign Measurements
Heart rate, systolic and diastolic blood pressure, and temperature (‘vital signs’) will be assessed 
as outlined below; assessments may be obtained in either the supine or seated position obtained 
after the subject has been in the supine or seated position for 5 minutes. 
If, in the opinion of the Investigator, a clinically significant vital sign change occurs, then the 
measurement will be repeated at medically appropriate intervals until the value returns to within

an acceptable range. Temperature will be collected at Screening (Visit 1) and at pre-dose at all 
visits and will not be repeated post-dose.
Obtain heart rate and SBP/Diastolic blood pressure (DBP), as directed below:  
•
At Screening (Visit 1): Baseline measures will be obtained.
•
At Day 1 of each TP (Visits 2 and 4): Prior to study drug administration and after study 
drug administration. 
•
At Day 15 (± 5 days) of each TP (Visits 3 and 5): Prior to study drug administration and 
after study drug administration. 
Note: Any clinically relevant findings from vital sign measurements will be reported as adverse 
events.
7.2.3
12-Lead Electrocardiogram 
Twelve-lead ECGs will be performed as described below: 
Twelve-lead ECGs will be obtained during Screening (Visit 1), at Day 1 of each TP (Visit 2 
(Randomization) and Visit 4), and at Day 15 (± 5 days) of each TP, (Visits 3 and 5), as follows:
x
At Visit 1 (Screening): Each subject will undergo a 12-lead ECG 
x
At Visit 2 (Randomization) and Visit 4: Each subject will undergo a 12-lead ECG obtained 
approximately 60 min prior to study drug administration and approximately 90 min after study 
drug administration.
x
At Visits 3 and 5 (Day 15 ± 5 days of each TP): Each subject will undergo a 12-lead ECG 
approximately 60 minutes prior to study drug administration and approximately 90 minutes 
after study drug administration.
Note: Baseline ECG values are defined as the last value obtained prior to dosing on Day 1 of 
Treatment Period 1 (Visit 2) and Treatment Period 2 (Visit 4).  Electrocardiogram parameter 
assessments include: heart rate, PR interval, QRS duration, QT interval, and QTcF.
Note: The study team is encouraged to maintain study timepoints.
Note: Any clinically relevant findings from ECGs will be reported as adverse events.
ECG values will be checked by the investigator or designee.
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,

TP 2 (Visit 4), the Investigator will make a determination on the suitability of continuing the 
subject in the study. Refer to Section 5.7 for specific criteria for QTcF that prompt subjects to be 
discontinued from the study. If QTcF interval prolongation exceeding these limits is verified 
during treatment, the subject’s medical background should be examined closely for risk factors

that may have contributed to the event, including genotyping for hereditary long QT syndromes, 
if appropriate.  
Every clinical significant deviation after the subject is randomized in this study must be recorded 
as an AE and reported to the Sponsor.
The decision to continue the treatment of any subject with prolonged QT or QTcF interval must 
be discussed and agreed upon by the Investigator and the Sponsor. 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 Sponsor must be contacted.
7.2.4
Clinical Laboratory Tests
Clinical safety laboratory tests will be analyzed by local laboratory according to standardized, 
validated assays. The laboratory will supply detailed instructions and all containers for blood and 
urine investigations.  Blood sample volumes will meet the laboratory’s specification. All clinical
laboratory tests will be obtained at Visit 1 (Screening) and prior to dosing at Visit 2 (Day 1 of TP 
1), Visit 3 (Day 15 ± 5 days of TP 1), Visit 4 (Day 1 of TP 2) and Visit 5 (Day 15 ± 5 days of TP 
2) or Premature Discontinuation Visit.

Visit.
If any of these tests are positive, the subject must be discontinued from the study. The pregnancy 
test should be performed at the beginning of the visit.
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 case report form. If the AE is “alarming,” the Investigator must report 
the 
AE 
immediately 
to 
Pearl. 
In 
addition, 
certain 
AEs 
(as 
described 
in 
Section 7.3.7) are classified as "serious" and must be reported no later than 24 hours after the 
Investigator recognizes/classifies the event as a SAE to Pearl or its designee.
In the case of SAEs, after discussing the details of the AE, the Investigator and the Sponsor may 
discontinue the subject prematurely.
7.3.2
Adverse Event Definitions
The following definitions of terms are guided by the International Conference on Harmonisation 
of Technical Requirements for Registration of Pharmaceuticals for Human Use (ICH), the US 
Code of Federal Regulations (21 CFR 312.32) and EU Directive 2001/83/EC and are included 
herein.
An AE is any untoward medical occurrence associated with the use of a drug in humans, whether 
or not considered drug related. An AE (also referred to as an adverse experience) can be any 
unfavorable and unintended sign (eg, an abnormal laboratory finding), symptom, or disease 
temporally associated with the use of a drug, without any judgment about causality. An AE can 
arise from any use of the drug (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:
•
Any symptom or condition not previously reported by the subject (medical history).
•
An exacerbation of a pre-existing symptom or condition.
•
A significant increase in frequency or intensity of a pre-existing episodic event or condition.
•
A drug interaction.
•
A condition first detected or diagnosed after study drug administration even though it may 
have been present prior to the start of the study.

Page 70 of 123
An AE does not include:
•
Medical or surgical procedures (e.g., surgery, endoscopy, tooth extraction, blood 
transfusion); the condition that results in the procedure is considered an AE (eg, bleeding 
esophageal varices, dental caries).
•
Overdose of either study drug or concurrent medication without any clinical signs or 
symptoms.
•
Non-clinically significant abnormal laboratory values. (If accompanied by signs/symptoms, 
the signs or symptoms are considered an AE).
7.3.3
Pre-Randomization Adverse Events
AEs that occur between the time subject signs the ICF for the study and the time when that 
subject is randomized will be summarized as medical history and not as a Treatment Emergent 
AE (TEAE) unless the event meets the definition of a SAE as defined in 
Section 7.3.7.
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 AE to the study drug administration will be assessed by the Investigator 
after careful consideration, and according to the following guidelines:
Definitely: A reaction that follows a reasonable temporal sequence from administration of study 
drug; that follows a known or expected response pattern to the study drug; it disappears or 
decreases on cessation or reduction in study drug dose; and/or it reappears or worsens when the 
study drug is administered.
Probably: A reaction that follows a reasonable temporal sequence from administration of study 
drug; that follows a known or expected response pattern to the study drug; and/or that could not 
be reasonably explained by other factors such as underlying disease, complications, concomitant 
drugs, or concurrent treatments.

Possibly: A reaction that follows a reasonable temporal sequence from administration of study 
drug; that follows a known or expected response pattern to the study drug, but that could 
reasonably have been produced by a number of other factors including underlying disease, 
complications, concomitant drugs, or concurrent treatments.
Not Related: A reaction for which sufficient data exist to indicate that the etiology is unrelated to 
the study drug.
7.3.6
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 (eg, elevated BUN and creatinine in the setting of an 
AE of renal failure, or decreased hemoglobin in a case of bleeding esophageal varices).  In such 
cases, the laboratory abnormality itself (eg, elevated creatinine in a setting of renal failure) does 
not need to be recorded as an AE. However, isolated laboratory abnormalities should be reported 
as AEs if they are considered to be clinically significant by the Investigator.
Criteria for a "clinically significant" laboratory abnormality are:
•
A laboratory abnormality that leads to a dose-limiting toxicity (eg, an abnormality that results 
in study drug dose reduction, suspension, or discontinuation)
•
A laboratory abnormality that results in any therapeutic intervention (ie, concomitant 
medication or therapy)
•
Other laboratory abnormality judged by the Investigator to be of any particular clinical 
concern (eg, significant fall in hemoglobin not requiring transfusion)
For laboratory abnormalities that do not meet the above criteria but are outside of normal range 
(eg, < or > normal reference range), the Investigator should indicate whether the value is 
clinically significant or not clinically significant for the subject.
7.3.7
Serious Adverse Events
An AE is considered “serious” if, in the view of the Investigator or Sponsor, it results in any of 
the following outcomes:
•
Death
•
A life-threatening AE
•
In subject hospitalization or prolongation of existing hospitalization 
•
A persistent or significant incapacity or substantial disruption of the ability to conduct 
normal life functions
•
A congenital anomaly/birth defect
Important medical events that may not result in death, be life threatening, or require 
hospitalization may be considered serious when, based upon appropriate judgment, they may

jeopardize the subject and may require medical or surgical intervention to prevent one of the 
outcomes listed in the definition. Examples of such medical events include allergic 
bronchospasm requiring intensive treatment in an emergency room (ER) 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 a SAE.
An AE or suspected adverse reaction is considered “life-threatening’ if, in the view of the 
Investigator or Sponsor, its occurrence places the subject or subject at immediate risk of death. It 
does not include an adverse reaction or suspected adverse reaction that, had it occurred in a more 
severe form, might have caused death.
An AE or suspected adverse reaction is considered unexpected if it is not listed in the current 
Investigator Brochure or is not listed at the specificity or severity that has been observed.
7.3.7.1
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 
Pharmacovigilance or designee no later than 24 hours after the Investigator recognizes/classifies 
the event as a SAE. At a minimum, a description of the event and the Investigator’s judgment of 
causality must be provided at the time of the initial report using the appropriate form (eg, SAE 
Report Form). After the initial report, as necessary, the Investigator must provide any additional 
information on a SAE to Pearl Pharmacovigilance or designee within 2 working days after he/she 
receives additional follow-up information this follow-up information will be a detailed written 
report that may include copies of hospital records, case reports, and autopsy reports, and other 
pertinent documents.
Post-study SAEs following the last dose of study drug must be reported to Pearl as described in 
Section 7.3.7.3.
The Investigator is responsible for continuing to report any new or relevant follow-up
information that he/she learns about the SAE.
7.3.7.2
Supplemental Investigations of SAEs
The Investigator and supporting personnel responsible for subject care should discuss with the 
Medical Monitor any need for supplemental investigations of SAEs. The results of these 
additional assessments conducted must be reported to Pearl. If a subject dies during participation 
in the study and a post-mortem examination is performed, a copy of the autopsy report must be 
submitted to Pearl Pharmacovigilance.

Page 73 of 123
7.3.7.3
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. 
7.3.7.4
Notification of Post-Study Serious Adverse Events
The follow up telephone call will be performed 7 – 10 days after Visit 5 so post-study SAEs 
occurring up to 10 days following the last dose of study drug must be reported to Pearl, whether 
or not the event is attributable to study drug. All SAEs must be reported to Pearl no later than 
24 hours after the Investigator recognizes/classifies the event as a SAE.
7.3.7.5
IRB/IEC Notification of Serious Adverse Events
The Investigator is responsible for notifying her/his IRB/IEC of all SAEs, including any follow-

Obtain a new chest x-ray if the chest x-ray or CT scan performed within 6 months of Visit 1 (Screening) is not available.
i
After informed consent is obtained, prohibited COPD medications will be stopped 6 hours to 24 hours before Visit 1 (Screening). At Visit 1 COPD 
medications will be changed as specified in the protocol (i.e., Sponsor provided Atrovent HFA with or without ICS).  At the end of Visit 5, return 
subject to pre-study or other appropriate inhaled maintenance COPD medications.
j
Site should use the sponsor provided placebo MDI to train subjects on the use of MDIs.
k
Sponsor provided Atrovent HFA or Ventolin HFA should be dispensed only after a subject is determined to be eligible to proceed to Visit 2 (Day 
1) (i.e., only if a subject meets the definition of COPD following spirometry assessments at Screening).
l
In-clinic dosing time is recorded as time of the second puff/inhalation.  
m
Refer to Appendix 6 for details and instructions on recording dose indicator readings.
n
Visit windows during each Treatment Period are relative to Day 1 of that Treatment Period. Washout period between Visit 3 and Visits 4 is a
minimum of 5 days to a maximum of 21 days. 
o
The inhalation profile with the use of the respiration belt will be measured simultaneously with the drug administration.
p
Only in female of childbearing potential.
q
AEs that occur before randomization will be summarized as medical history and not as a TEAE unless the event meets the definition of a SAE 
(Refer to Section 7.3.3).
r
All prescription and OTC medications taken by the subject within 30 days before Visit 1 (Screening) will be recorded.
s
The number of COPD exacerbations requiring oral steroids and/or oral antibiotics, or hospitalization within 12 months of Visit 1 (Screening) will 
be collected.  
t
At Visit 2 and 4 two breathing levels: TLC and FRC. During Visit 2 an additional scan of the UA will be taken. At Visit 3 and 5 one breathing 
level: TLC.
u
Subjects who are unable to meet the compliance requirement (>70% subject completion of diary assessments) in the last 7 days preceding the 
Randomization Visit (Visit 2) must be retrained. When retraining is required due to non compliance the Randomization Visit (Visit 2) must be 
rescheduled.
Note: Site should plan to perform these activities so as not to interfere with collection of timed assessments such as spirometry. Where data collection 
time-points are concurrent, variables must be collected in the following order: On Day 1 of each treatment period: Predose: Urine pregnancy 
test, Spirometry (obtain FEV1 to evalutate stability criteria), vital signs, ECG, clinical laboratory assessments (Abnormal eGFR at Visit 1 
[screening] must be repeated prior to visit 2 and have the results available at Visit 2 to confirm eligibility), Pre-dose CT scans, Spirometry, 
Body Plethysmography, Inhalation Profile. Postdose: vital signs, ECG. On Day 15 (± 5 days) of each TP: Predose: Urine pregnancy test, vital 
signs, ECG, clinical laboratory assessments Postdose: Vital signs, ECG, post-dose CT Scan, Spirometry, Body Plethysmography.

Efficacy Analyses
9.3.1
Efficacy Analysis
For the efficacy analyses, the individual effects of both GP MDI and FF MDI will be assessed. 
The effect is defined as the difference between the value at Day 15 and the value at Day 1. Effect 
is thus the change from baseline to GP MDI, for a GP MDI treatment and as the change from 
baseline to FF MDI, for a FF MDI treatment.
For each parameter in each group (primary efficacy endpoints: FRI; secondary efficacy endpoints: 
FRI, spirometry and body plethysmography; other efficacy endpoints: all FRI parameters except the 
mass of deposited particles, spirometry and body plethysmography), this effect will be assessed. 
Additional analyses will compare the distribution of regional effects between the two treatments 
for the different FRI endpoints. A linear mixed model approach will be chosen and specified 
fully in the statistical analysis plan.
In order to gain extra insights in the mode of action of the product, additional exploratory 
analyses can be executed using (robust) linear regression or mixed-models. The results of the 
PT003019-00 study can be combined with the results of the PT003018-00 (EudraCT: 2015-
001743-36) for further examination.
The Intent-to-Treat (ITT) Population will be considered the primary analysis population for 
efficacy. Supportive analyses will be conducted with the Modified Intent-to-Treat (mITT) 
Population.
9.3.2
Control of Type I error
For the primary outcome parameters, Hochberg's step-up procedure will be used as multiplicity 
adjustment within each product. No correction will be performed for the secondary or other 
endpoints.
9.3.3
Safety Analysis 
9.3.3.1
Adverse Events
Adverse events during each TP will be summarized by the number of subjects experiencing an 
event. 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.
Note: Any clinically relevant findings from ECGs, clinical laboratory tests (e.g. Hematology, 
Clinical Chemistry), or vital sign measurements will be reported as adverse events.

9.4
Randomization
Subjects will be randomly assigned to one of two treatment sequences in a block size of 4 for the 
two sequences. Each sequence will include exactly one of the two treatment groups included in 
this study per TP. All subjects will receive GP MDI 14.4 ȝg and FF MD I9.6 ȝg.
The two treatment sequences are shown below:
Table 9-12. Randomization Schedule

Experimental design
The experimental design was chosen to be balanced with respect to period and first-order 
carryover effects.
9.6
Sample Size Consideration
In a double-blind, cross-over study where 10 COPD Global Initiative for Chronic Obstructive 
Lung Disease (GOLD) III subjects received a budesonide/formoterol combination; FRI was able 
to quantify the effects of the active compound relative to baseline. A sample size calculation 
(power goal 90%, alpha 0.05) revealed that in order to have a well-powered study with change in 
imaging based airway volume as primary outcome parameter, a total of 16 subjects would be 
required (De Backer, 2012). If the significance level for the volume is set to 0.025 by the 
Hochberg's step-up procedure, 20 subjects would be required. It can be assumed that sufficient 
power will be obtained when including 20 subjects.
9.7
Data Validation and Transformation
All measured values will be included in the analyses. Depending on the plots of the standardized 
residuals versus fitted values of the mixed-effect models, data transformations will be considered

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: 
•
The ITT Population is defined as all subjects who are randomized to treatment. Treatment is 
assigned as randomized regardless of the treatment actually received. 
•
The modified Intent-to-Treat (mITT Population) is a subset of the ITT Population 
including subjects who received treatment and have post-treatment efficacy data from 
both TPs. 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.
•
The Safety Population is defined as all subjects who are randomized to treatment and 
receive at least one dose of the study treatment. Statistical analyses and tabulations will be by 
the treatment actually received.
Analyses will be performed as follows: 
Demographics will be summarized for the ITT, mITT and Safety populations. Extent of exposure 
will be summarized for the Safety Population. The Safety Population will be used to summarize 
safety data.
Efficacy analyses will be performed for the ITT and mITT Populations, with the ITT Population 
being considered the primary population for these analyses. 
9.10 Handling of Missing Data 
No imputation for missing values is planned. 
9.11 Statistical Software 
All analyses will be performed using the open-source statistical environment

in the investigational product.
10.11 Investigator's Final Report
Shortly after completion of the Investigator's participation in the study, the Investigator will 
submit a written report to Pearl.
10.12 Publication Policy
Pearl intends to publish the results of all of the clinical studies that it sponsors in compliance 
with the Declaration of Helsinki (http://www.wma.net/en/10home/index.html). Consistent with 
the recommendations of the editors of several leading medical journals, the International 
Committee of Medical Journal Editors (ICMJE), authorship of publications resulting from Pearl -
sponsored studies should fairly recognize the activities of those that have made a significant 
contribution to the study. Thus, it is anticipated that authorship will reflect the contribution made 
by Pearl personnel, the Investigators and others involved, such as statisticians.
In recent years, issues about conflicts of interest and accuracy of the study data have been raised 
in the medical press. Accordingly, Pearl has developed publication guidelines as described 
below:
1. Responsibility: Each principal Investigator is responsible for the accuracy and completeness 
of all data from their site. Pearl (or its representatives) is responsible for the accuracy of the 
data entered into the study databases and for the accuracy of the analyses conducted.
2. Authorship and Publication Committee: Pearl, in collaboration with the Investigators, will 
establish the appropriate authorship and responsibility for drafting study documents in 
accordance with the principles of the ICMJE. It is anticipated that a publication committee 
will be formed to assume oversight of these activities. All manuscripts will be reviewed and 
agreed upon before submission for publication by all authors.
3. Sponsor Review of External Manuscripts: Consistent with the previous bullet point, drafts 
of any and all publications or presentations that may arise from this study must be submitted 
at least 30 days prior to submission for publication or presentation to Pearl for review,

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

12 APPENDICES
Appendix 1
Subject Instructions for Use of GP and FF MDI
Before using GP MDI and FF 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 A1-1.
Figure A1-1. 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 GP MDI and FF 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 GP MDI and FF 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 GP MDI and FF 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 
(see Figure A1-2).  
Figure A1-2. Wash Actuator through Top of Actuator
3. Then wash the actuator again through the mouthpiece (see Figure A1-3).

Figure A1-3. 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.

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

Protocol of HRCT scan and CFD method  
1 Protocol of CT scan 
For small airways scanning thorax HRCT scans are taken at Visit 2, Visit 3, Visit 4 and Visit 5. 
The scans on Visit 2 and Visit 4 are taken at two different lung volumes, i.e. TLC and FRC, 
during breath hold. The scans on Visit 3 and Visit 5 are only taken at TLC level. In order to 
control the lung volume, the subjects’ breathing signal is monitored. During Visit 2 an additional 
scan of the upper airway will be taken. The scans will be taken with a 
 64-
slice scanner or a scanner yielding equivalent results.
Monitoring the breathing signal: 
In order to monitor the breathing signal, the subject breaths through a mouthpiece. This 
mouthpiece is connected with a laptop (via a networkcable long enough to bridge the distance 
between subject in the CT room and the control room) on which specialized software is running. 
Through a pneumotach in the mouthpiece the flow pattern can be followed. For TLC we ask the 
subject to breath in fully and to hold his breath for the duration of the scan. When we see the 
subject is correctly holding his breath, a CT scan is taken. The same procedure is repeated at 
FRC. We ask the subject to breath in a bit and to slowly blow out until FRC and to hold his 
breath. At that moment the second CT scan is taken. For the upper airway scan we ask the 
subject to breath in slowly while the scan is taken. 
Scanning protocols: 
For the TLC Scan and FRC scan:
•         Rotation time of 0.6 s 
•         Detector coverage of 40 mm 
•         Helical thickness of 0.625 mm 
•         Pitch and speed of 1.375:1 and 55 mm/s. 
•         Tube voltage: 100 kV 
•         Tube current: variable between 10 and 200 mAs 
•         Noise index: 45 
The field of view is set as small as possible, but the lung should be seen completely in all axial 
slices. Scan time lies around 5 seconds. Images are reconstructed at 0.3 mm interval using a lung 
filter. The resulting data set has 700-1200 images with a pixel size of 0.4-0.65 mm2. 
UA scan
•         Rotation time of 0.5 s 
•         Detector coverage of 40 mm 
•         Helical thickness of 1.250 mm 
•         Pitch and speed of 0.984:1 and 39.37 mm/s. 
•         Tube voltage: 100 kV
