SUMMARY OF CHANGES TO AMENDED PROTOCOL PT001102-04 
(VERSION 5.0), DATED 08 MARCH 2019
The amended study protocol, PT001102-04 (Version 5.0), includes the following edits:
No.
Description of Change
Rationale
1
Removed Visit 5 (Week 4) post-dose 
vital sign measurements
Sections affected:
7.2.2 Vital Sign Measurements
8.1 General Study Considerations 
(Table 8-2 Sequence and Timing for 
Selected Assessments at Treatment 
Visits 4 through 10)
Post-dose spirometry assessment was 
removed from Visit 5 in Amendment 
03, but post-dose vital signs at Visit 5 
were left in error.  This assessment has 
now been removed as there should be 
no post-dose assessments performed at 
Visit 5.
2
Reduced the time gaps around Visits 1, 
2, and 3 by 2 days 
Sections affected:
4.1 Study Design (Figure 4-1 Study 
Design Overview)
8.1 General Study Considerations 
(Table 8-1 Schedule of Events)
8.4 Visit 3 (Day -20 to Day -1)
Holter monitoring sub-study is 
complete and the extended time gaps 
around Visits 1, 2, and 3 are no longer 
needed.
3
Added height requirement at Visits 4, 5, 
and 7 for subjects 12 to 18 years of 
age
Sections affected:
7.2.1 Medical/Surgical/Asthma 
Exacerbation History and Physical 
Examination
8.1 General Study Considerations 
(Table 8-1 Schedule of Events)
8.5 Visit 4 (Randomization, Day 1)
8.6 Visits 5, 6, 8, and 9 (Weeks 4, 8, 16, 
and 20)
8.7 Visit 7 (Week 12)
8.8 Final Visit (Visit 10, Week 24)
Height is needed for subjects 12 to 18 
years of age in order to calculate 
creatinine clearance using the Schwartz 
formula.

No.
Description of Change
Rationale
4
Age range for creatinine clearance 
equations corrected.
Sections affected:
5.2, Exclusion Criterion #13
5.9.1, Reasons for Study Drug 
Discontinuation
7.2.5, Clinical Laboratory Tests (Table 
7-2 List of Clinical Safety Laboratory 
Tests)
Clarification that subjects 18 years of 
age should have the Schwartz equation 
used for creatinine clearance only if the 
day of the visit is on their 18th birthday.
5
Moved rate of moderate/severe asthma 
exacerbation from an “other” 
endpoint to a secondary endpoint and 
time to first moderate/severe asthma 
exacerbation from a secondary 
endpoint to an “other endpoint”
Sections affected:
Synopsis
3.2 Secondary Efficacy Endpoints
3.3 Other Endpoints
9.5.2.2 Rate of Moderate/Severe 
Asthma Exacerbations
9.5.3.3 Time to First Asthma 
Exacerbation
9.5.3.4 Rate of Severe Asthma 
Exacerbation or Exacerbations of 
Any Severity
In situations where multiple subjects 
experiencing an event tend to 
experience more than one event, an 
analysis of the event rate is more 
powerful than an analysis of time to 
first event.  A blinded review of data 
from this study indicates that there are 
more events than subjects with at least 
one event.  Hence, the hierarchy order 
will be switched for the rate and time to 
first analyses of moderate/severe 
exacerbations.
6
Changed PEFR analysis at each clinic 
visit to over 4-week intervals 
Sections affected:
9.5.3.8 Change from Baseline in 
Morning PEFR and Evening PEFR
Clarification that PEFR will be 
analyzed over 4-week intervals 
7
Amended censoring wording for 
CompEx endpoint for remove Day 
168
Sections affected:
9.5.3.10 CompEx
Clarification that CompEx will be 
censored at the Week 24 visit only

Pearl Therapeutics, Inc. (Pearl)
Name of Study Drug
Glycopyrronium Inhalation Aerosol (PT001, GP metered dose inhaler [GP MDI])
Name of Active Ingredient: Glycopyrronium
Study Title: A Randomized, Double-Blind, Parallel Group, Multi-Center 24-Week Study 
Comparing the Efficacy and Safety of Three Doses of PT001 to Placebo and Open-label 
Spiriva® Respimat® in Subjects With Persistent Asthma
Study Protocol Number: PT001102-04
Study Phase: II/III 
Primary Objective: To assess the effect of 3 doses of GP MDI compared to Placebo 
MDI and Spiriva® Respimat® on lung function over 24 weeks in subjects with persistent 
asthma.
Secondary Objective: To assess the effect of 3 doses of GP MDI compared to Placebo 
MDI and Spiriva Respimat on exacerbations, quality of life, and symptoms over 24 weeks 
in subjects with persistent asthma.
Safety Objective: To assess the safety of 3 doses of GP MDI compared to Placebo MDI 
and Spiriva Respimat over 24 weeks in subjects with persistent asthma.
24-Hour Holter Monitoring Sub-Study Objective: To assess the cardiovascular safety 
of 3 doses of GP MDI compared to Placebo MDI and Spiriva Respimat as evaluated by 
24-hour Holter monitoring.
Study Design
This Phase II/III randomized, double-blind, parallel group, multi-center, dose 
confirmation study will compare 3 doses of GP MDI (28.8, 14.4, and 7.2 μg) to Placebo 
MDI and open-label Spiriva Respimat (2.5 μg). The 3 doses of GP MDI and the Placebo 
MDI will be administered twice daily (BID) and Spiriva Respimat will be administered 
once daily (QD), both for 24 weeks.
At Visit 1, subjects will sign an informed consent form (ICF) and assent form (as 
applicable) and inclusion/exclusion criteria will be assessed. All eligible subjects must 
have been taking a stable regimen of an inhaled corticosteroid (ICS)/long-acting β2-
agonist (LABA) for at least 4 weeks, and be willing to continue this medication regimen 
throughout the trial. Subjects also taking tiotropium 2.5 μg QD for at least 4 weeks prior 
to Visit 1 may be enrolled if they are willing to discontinue tiotropium at Visit 1. 
Tiotropium will be replaced with Sponsor-provided ipratropium bromide 
hydrofluoroalkane (hereafter referred to as ipratropium) taken as 2 inhalations 4 times 
daily until randomization, when ipratropium will be discontinued. Sponsor-provided

albuterol for rescue use will be dispensed and subjects will begin recording their asthma 
medications, peak expiratory flow rates, asthma symptom scores, and rescue albuterol use 
in an electronic diary. 
Subjects must demonstrate a forced expiratory volume in 1 second (FEV1) of >40% and 
<85% of predicted (>40% and <90% of predicted for subjects 12 to <18 years of age) at 
Visit 1 (and Visit 2 if spirometry is required), and must demonstrate reversibility to 
albuterol at Visit 1 or Visit 2. 
Subjects will return for Visit 2 after adequate washout of prohibited asthma medications.
There will be a minimum of 7 days between Visit 1 and Visit 2. Spirometry will only be 
performed at Visit 2 if reversibility criteria to albuterol were not met at Visit 1. The 
Asthma Control Questionnaire (ACQ) will be administered, and multiple other 
assessments will be made including fractional nitric oxide in inhaled breath (FENO).
At Visit 3, reversibility of FEV1 to ipratropium will be assessed for characterization and 
randomization stratification. For subjects participating in the Holter monitoring sub-
study, a 24-hour Holter monitor will also be placed.
At Visit 4, subjects meeting randomization criteria (including demonstrating an FEV1 of 
>40% and <85% of predicted [>40% and <90% of predicted for subjects 12 to <18 years 
of age]) will be randomized in a 2:2:2:2:1 scheme to 1 of the following 5 treatment 
groups:
•
GP MDI 28.8 μg BID (double-blind)
•
GP MDI 14.4 μg BID (double-blind)
•
GP MDI 7.2 μg BID (double-blind)
•
Placebo MDI BID (double-blind)
•
Spiriva Respimat 2.5 μg QD (open-label)
Randomization will be stratified by baseline percent predicted FEV1 (≤60% or >60%), 
reversibility to ipratropium (<12% or <200 mL vs ≥12% and ≥200 mL improvement in 
FEV1), and by the ICS included in their fixed-dose ICS/LABA combination product 
(budesonide [eg, Symbicort®, with formoterol fumarate dihydrate], mometasone furoate 
[eg, Dulera®, with formoterol fumarate dihydrate], fluticasone furoate [eg, Breo® Ellipta®, 
with vilanterol trifenatate], or fluticasone propionate [eg, Advair® or AirDuo™ 
RespiClick®, with salmeterol]).
Following randomization, subjects will enter the Treatment Period and undergo 6 
additional treatment visits over 24 weeks. For subjects participating in the Holter 
monitoring sub-study, a Holter monitor will be placed at Visit 7 and removed the 
following day.
Subjects who discontinue randomized study drug prior to the end of the study will be 
encouraged to remain in the study to complete all remaining study visits and procedures.

24-Hour Holter Monitoring Sub-Study: Holter monitoring will be conducted over 24 
hours in a subset of approximately 562 randomized subjects (125 subjects in each GP 
MDI group and the Placebo MDI group and 62 subjects in the Spiriva Respimat group) at 
Visit 3 (Holter monitoring baseline) and Visit 7 (Week 12).
Study Population: Approximately 2250 subjects with persistent asthma who are 
symptomatic despite treatment with a fixed-dose ICS/LABA (± tiotropium) will be 
recruited in order to enroll approximately 1125 subjects into the randomized Treatment 
Period. This study will be conducted at approximately 250 sites in the United States with 
each site enrolling approximately 4 to 6 subjects.
Test Product, Dose, Strength, and Mode of Administration

Statistical Methods
Primary Efficacy Analysis
Change from baseline in FEV1 AUC0-4 will be analyzed using a linear repeated measures 
analysis of covariance model for the Efficacy Estimand. The model will include 
treatment, visit, background ICS/LABA, and treatment by-visit interaction as categorical 
covariates and baseline FEV1, percentage reversibility to ipratropium, and blood 
eosinophil count at screening as continuous covariates.
Sample Size
A sample size of 1125 subjects (250 subjects per double-blind treatment group, 
125 subjects in the open-label Spiriva Respimat treatment group) will provide 
approximately 93% power to detect a 120 mL difference between the GP MDI treatment 
groups and Placebo MDI in the analysis of change from baseline in FEV1 AUC0-4 at 
Week 24. The assumed standard deviation is 348 mL at each visit. The 2-sided alpha for 
each pairwise comparison is 0.05. This sample size assumes that approximately 20% of 
randomized subjects will have discontinued study drug prior to Week 24.
Comparisons of GP MDI to Spiriva Respimat will be focused on estimation as the study 
is not formally powered to demonstrate non-inferiority or superiority.
Data Monitoring Committee:
An independent, external Data Monitoring Committee (DMC) will be set up to review all 
serious adverse events (including deaths and all hospitalizations) and cardiovascular 
events. Members of the DMC will review summaries of these safety data generated 
externally and independently of the Sponsor in a semi-blinded or unblinded manner at 
predetermined intervals. If significant safety issues arise in between scheduled meetings, 
ad hoc meetings will be scheduled to review the data. Based on the safety implications of 
the data, the DMC may recommend modification or termination of the study.

INTRODUCTION
The Sponsor is developing a family of orally inhaled drug products containing budesonide, 
glycopyrronium, and/or formoterol fumarate as single agents, dual combinations, and a triple 
combination product. These drug products are metered dose inhalers (MDIs) formulated as a 
suspension with micronized active pharmaceutical ingredients and Co-Suspension™ 
Delivery Technology. The Co-Suspension Delivery Technology consists of spray-dried 
porous particles comprised of the phospholipid 1,2-distearoyl-sn-glycero-3-phosphocholine 
and calcium chloride suspended in a hydrofluoroalkane (HFA) propellant. When used in 
combination MDI products, these particles form strong non-specific associations with the 
active pharmaceutical ingredients, preventing the drugs from interacting with each other in 
the suspension and providing reproducible drug delivery and long-term stability.
The test formulation to be evaluated in this study is an MDI containing Glycopyrronium 
Inhalation Aerosol (henceforth referred to as GP MDI), a long-acting muscarinic antagonist 
(LAMA). Further details about the to-be-tested formulations are provided in Table 6-1 and 
the current version of the PT001 investigator brochure (IB).
1.1
Background Information on the Treatment of Asthma
Asthma is a heterogeneous disease that is characterized by chronic airway inflammation and 
bronchial hyperreactivity. It is defined by a history of respiratory symptoms such as wheeze, 
shortness of breath, chest tightness, and cough that vary over time and in intensity, together 
with variable expiratory airflow obstruction. The variations in symptoms and airflow 
obstruction are often triggered by factors such as exercise, allergen or irritant exposure, 
changes in weather, noxious fumes, or viral respiratory infections. Symptoms and airflow 
obstruction may resolve spontaneously or in response to therapy. Importantly, worsening 
asthma symptoms/airway obstruction can be severe, resulting in an asthma exacerbation that 
may be life-threatening. Such events pose a significant burden to patients and result in 
significant direct and indirect economic costs (Global Initiative for Asthma [GINA] 2017).
The main objective of asthma treatment is to maintain asthma control (GINA 2017). The 
concept of ‘asthma control’ is not synonymous with ‘asthma severity’ and is defined as ‘the 
extent to which the various manifestations of asthma have been reduced or removed by 
treatment’. This concept encompasses 2 components: the patient’s recent clinical 
status/current disease impact (symptoms, night awakenings, use of rescue medication, and 
lung function) and future risk (exacerbations, decline in lung function, or treatment-related 
side effects). According to the GINA guidelines, asthma is controlled when a patient has 
daytime symptoms twice or less per week, no limitation of daily activities, no nocturnal 
symptoms, no exacerbations, the need for rescue medication use is twice or less per week, 
and normal or near normal lung function.
The GINA guidelines specify 5 treatment steps for asthma, each step outlining options for 
higher levels of treatment for controlling asthma in patients 5 years of age and older 
(GINA 2017). Within this stepwise approach, GINA proposes a classification of asthma 
severity based on the type and intensity of controller medication required for the control of

the disease (Steps 1 to 5). The GINA guidelines also propose a classification in 3 categories 
(mild, moderate, and severe asthma) assessed retrospectively once the patient is on regular 
controller treatment for several months.
Per GINA guidelines, the goal of the stepwise approach to treatment is to achieve and 
maintain control. In this regard, the level of asthma control obtained with treatment 
determines the need to step up or step down to the next treatment step in order to achieve 
optimum control with the minimum amount of medication. The majority of asthma patients 
can achieve and maintain clinical control with standard treatment regimens that generally 
include inhaled corticosteroids (ICSs) with or without inhaled long-acting β2-agonists 
(LABAs) as well as short-acting β2-agonists (SABAs). However, some patients with asthma 
have inadequately controlled disease despite the use of an ICS with or without a LABA. 
Treatment options that may be considered in these patients include adding a LAMA such as 
tiotropium and, in certain subsets of patients, biologic agents (eg, omalizumab, 
mepolizumab), bronchial thermoplasty, and low-dose oral corticosteroids (GINA 2017).
This information indicates that LAMAs have a significant role in the management of asthma 
when used in combination with other controller medications (Barnes 2011). The goal of the 
current study is to evaluate the safety and efficacy of 3 doses of GP MDI in comparison to 
Placebo MDI and Spiriva® Respimat® over 24 weeks in subjects whose asthma is not 
optimally controlled despite treatment with an ICS/LABA or an ICS/LABA plus tiotropium.

INVESTIGATIONAL PLAN
4.1
Study Design
This is a Phase II/III randomized, double-blind, parallel group, multi-center dose 
confirmation study comparing 3 doses of GP MDI (28.8, 14.4, and 7.2 μg) to Placebo MDI 
and open-label Spiriva Respimat (2.5 μg) in subjects with persistent asthma who are 
symptomatic despite treatment with an ICS/LABA or ICS/LABA + tiotropium. The 3 doses 
of GP MDI and the Placebo MDI will be administered twice daily (BID) and Spiriva 
Respimat will be administered once daily (QD), each for 24 weeks. The subject will also 
continue on their own ICS/LABA regimen during the Screening Period and throughout the 
Treatment Period.
Figure 4-1 displays the overall study design.
Figure 4-1
Study Design Overview
This study will be conducted at approximately 250 sites, contributing approximately 4 to 6 
subjects per site. It is planned that approximately 2250 prospective subjects will be screened, 
with approximately 1125 subjects randomized to provide approximately 900 subjects who 
complete the study.

At Visit 1, subjects (or the parents or legal guardians of subjects <18 years of age) will sign 
an informed consent form (ICF); subjects <18 years of age will sign an assent form. All 
eligible subjects must be taking a stable regimen of an inhaled corticosteroid (ICS)/long-
acting !2-agonist (LABA) for at least 4 weeks; this ICS/LABA regimen will be continued 
throughout the Screening and randomized Treatment Periods. Subjects who are also taking 
tiotropium will discontinue its use at Visit 1 and replace tiotropium with Sponsor-provided 
ipratropium bromide HFA MDI (hereafter referred to as ipratropium) taken as 2 inhalations 
4 times daily (QID) during the Screening Period. Beginning with Visit 1, subjects will use an 
eDiary BID to record ICS/LABA use (Screening Period only), albuterol sulfate HFA MDI 
(hereafter referred to as albuterol) use, asthma symptom scores, PEFR, and study drug use 
(Treatment Period only).
Subjects must demonstrate an FEV1 >40% and <85% of predicted (>40% and <90% of 
predicted for subjects 12 to <18 years of age) at Visit 1, Visit 2 (if applicable) and Visit 4.  
Reversibility to albuterol must be demonstrated at either Visit 1 or Visit 2. A subject will be 
considered reversible to albuterol if the improvement in FEV1 from pre-albuterol to post-
albuterol is ≥12% and ≥200 mL (Section 7.1.1.3).
Subjects will return for Visit 2 after adequate washout of prohibited asthma medications. 
There will be a minimum of 7 days between Visit 1 and Visit 2. At Visit 2, the ACQ will be 
administered along with multiple other assessments including FENO. Spirometry will only be 
performed at Visit 2 if reversibility to albuterol was not demonstrated at Visit 1.
A subset of approximately 562 subjects (125 subjects from the GP MDI groups and Placebo 
MDI group and 62 subjects from the Spiriva Respimat group) will participate in the 24-hour 
Holter monitor sub-study. In these subjects, a 24-hour Holter monitor will be collected 
between Visit 3 and Visit 4 (Holter Monitor Baseline) and at Visit 7 (Week 12). Those 
subjects who have clinically significant abnormal findings defined as (but not limited to) 
criteria in Section 5.5 during the baseline 24-hour Holter monitor MUST be screen failed 
from the full study. Subjects unable to provide a minimum of 18 hours of acceptable quality 
recording in a 24-hour period after 2 attempts will not be eligible for the Holter monitoring 
sub-study, but DO NOT need to be screen failed from the full study.
Reversibility to ipratropium will be assessed at Visit 3 for characterization and randomization 
stratification purposes. For subjects participating in the Holter monitoring sub-study, a 24-
hour Holter monitor will also be placed at Visit 3 (Section 7.2.4) and removed the following 
day.
Subjects meeting randomization criteria at Visit 4 (Section 5.3) will continue to take their 
same ICS/LABA regimen throughout the randomized Treatment Period, discontinue 
ipratropium (if applicable), and be randomized in a 2:2:2:2:1 scheme to 1 of the following 
5 treatment groups for 24 weeks:
•
GP MDI 28.8 μg BID (n=250)
•
GP MDI 14.4 μg BID (n=250)

reversibility to ipratropium (<12% or <200 mL vs ≥12% and ≥200 mL improvement in 
FEV1), and by the ICS included in their fixed-dose ICS/LABA combination product 
(budesonide [eg, Symbicort®, with formoterol fumarate dihydrate], mometasone furoate [eg, 
Dulera®, with formoterol fumarate dihydrate], fluticasone furoate [eg, Breo® Ellipta®, with 
vilanterol trifenatate], or fluticasone propionate [eg, Advair® or AirDuo™ RespiClick®, with 
salmeterol]).
Following randomization, subjects will undergo 6 additional treatment visits over 24 weeks. 
For subjects participating in the Holter monitoring sub-study, a Holter monitor will be placed 
at Visit 7 (Section 7.2.4) and removed the following day.
Note: The end of study is defined as the date on which data are collected 14 (+2) days after 
the last dose of study drug. Data collection can occur via a follow-up telephone call 
(Section 8.11) or a study visit, whichever provides 14 (+2) days of follow-up.
4.2
Rationale
GP MDI is being developed for use in the treatment of asthma. This study will characterize 
the efficacy and safety of GP MDI, evaluating multiple doses in order to determine the most 
appropriate GP MDI dose(s) to treat subjects with asthma who remain symptomatic despite 
treatment with an ICS/LABA.
4.2.1
Population
The primary intended use of GP MDI in asthma will be as add-on therapy to ICS/LABA in 
line with GINA guidelines (GINA 2017). This study will include subjects with persistent 
asthma who remain symptomatic, as demonstrated by an ACQ-5 (see Section 7.1.4.1) total 
score ≥1.5, despite treatment with an ICS/LABA. Symptomatic subjects receiving tiotropium 
in addition to an ICS/LABA are also included in order to cover the spectrum of asthma 
severity for which the addition of a LAMA to an ICS/LABA may be appropriate.
4.2.2
Choice of Study Doses
Efficacy and safety data from Phase I and II studies indicate that GP MDI 28.8, 14.4, and 
7.2 μg administered BID may be appropriate doses to evaluate in a Phase III study in subjects 
with uncontrolled persistent asthma despite treatment with an ICS/LABA. In a Phase II 
study, GP MDI 28.8 μg was most similar to salmeterol, the active comparator, for all 
outcome measures, and the GP MDI 14.4 and 7.2 μg doses were similar to salmeterol for 
some endpoints. GP MDI doses below 7.2 μg were appreciably less effective than salmeterol. 
The previous GP MDI Phase II study included subjects with asthma who were either on a

low dose of an ICS or not on an ICS. Therefore, confirmation of the optimal GP MDI dose in 
subjects with uncontrolled persistent asthma despite treatment with an ICS/LABA is 
warranted.
Doses above 28.8 μg have not been evaluated in subjects with asthma, and thus, the 28.8 μg 
dose is the highest dose planned for evaluation in this study. Furthermore, based on data from 
prior Phase I and Phase II studies, doses below 7.2 μg are not expected to have appreciable 
efficacy, and thus, the 7.2 μg dose is the lowest dose planned for inclusion in the study.
Refer to the current PT001 IB for further details on the Phase I and Phase II GP MDI studies. 
The dose chosen for Spiriva Respimat, 2.5 μg QD, is the approved dose in the current 
prescribing information for the treatment of asthma in individuals 6 years of age and older 
(Spiriva Respimat 2017).
4.2.3
Choice of Comparators/Control Groups
Spiriva Respimat will be included in this study as an active comparator to benchmark the 
GP MDI results. Placebo MDI will serve as the control arm. 
4.2.4
Study Duration
The specified study duration of 24 weeks will provide sufficient time to observe lung 
function changes in the chosen subject population. This is based on previous studies with 
tiotropium in asthma demonstrating that lung function changes plateau in 6 to 8 weeks and 
do not increase further in studies of up to 48 weeks in duration (Kerstjens 2015, 
Kerstjens 2012).

Other Restrictions, Illicit Drugs, and Drugs of Abuse
5.8.1
Illicit Drugs or Drugs of Abuse
Illicit drugs or drugs of abuse will not be allowed from Visit 1 to the end of the follow-up 
telephone call or to whenever the subject withdraws from the study. If any illicit drugs or 
drugs of abuse are used by the subject during the study, the dates of use and the amount will 
be documented and the subject will be discontinued from randomized study drug and 
withdrawn from the study at the discretion of the Investigator. 
Edible medical marijuana is not an exclusionary drug if used for medical purposes and there 
is no change in the dose or frequency of consumption during study participation (see also 
Section 5.7.2.2.3). Subjects who use medical marijuana by smoking or vaping are excluded.
5.8.2
Dietary Restrictions
Subjects must not ingest xanthine and/or xanthine analogue (caffeine)-containing foods or

If a subject experiences either of the below, the subject must be discontinued from study 
drug:
•
An asthma exacerbation requiring inpatient hospitalization
•
More than 2 severe asthma exacerbations requiring oral corticosteroid treatment
If a subject experiences any of the changes of concern listed below, a repeat assessment 
should be obtained, and if confirmed, the subject must be discontinued from study drug:
•
Calculated Fridericia-corrected QT interval (QTcF) of either >500 msec and a ≥30 msec 
change  from pre-dose baseline value obtained at Visit 4 OR a ≥60 msec change  from 
pre-dose baseline value obtained at Visit 4
•
Hepatic impairment, defined as an AST, ALT, or TBL concentration ≥3×ULN
If a subject experiences any of the following changes of concern, a repeat assessment should 
be obtained, and if confirmed, the Investigator needs to determine the suitability of 
continuing the subject on study drug:
•
A HR >120 bpm and in which there is an increase of >40 bpm from the pre-dose baseline 
value at Visit 4
•
A systolic blood pressure (SBP) >160 mmHg and an increase of >40 mmHg from the 
pre-dose baseline value at Visit 4
•
Either a decrease in creatinine clearance to a value ≤30 mL/minute using the CKD-EPI 
formula for subjects >18 to 80 years of age or the Schwartz formula for subjects 12 to 
≤18 years of age at Visit 1 (where ≤18 years of age is defined as anyone less than18 years 
up to and including their 18th birthday and >18 years of age is defined as 18 years +1 day 
and older) OR a clinically relevant change from pre-dose baseline obtained at Visit 4 as 
determined by the Investigator
Procedures for study drug discontinuation and study withdrawal are provided in Section 8.9.
5.9.2
Reasons for Study Withdrawal
If a subject becomes pregnant during the course of the study, she will discontinue study drug, 
and must be withdrawn from the study and followed until delivery or final outcome (see 
Section 7.3.12 for additional procedures).
Subjects may be withdrawn from the study at their own request or upon the request of the 
Investigator or the Sponsor at any time and for any reason (see Section 8.9 for additional 
procedures).

CLINICAL SUPPY LABELING, PACKAGING, STORAGE, 
DISPENSING, AND RETURN
Study personnel will have access to an IWRS to allocate subjects, assign study-related 
medication to subjects, and manage the distribution of clinical supplies. Each person 
accessing the IWRS system will be assigned a unique personal identification number (PIN) 
to use for their access. The assigned PIN must not be shared with anyone, even another 
colleague involved with the study.
Clinical supplies will be packaged according to a component schedule generated by the 
Sponsor or their designee. Subjects receiving tiotropium prior to Visit 1 will be supplied 
ipratropium in an open-label fashion during the Screening Period. Study drug for all 
treatments other than Spiriva Respimat will be packaged to support enrollment of the study in 
a blinded fashion for the 24-week Treatment Period; treatment with Spiriva Respimat will be 
open-label. 
The study drug and other medications provided by the Sponsor are described in Section 6.1
(randomized study drugs) and Section 6.2 (other medications). Medications to treat asthma 
exacerbations or other AEs will not be provided by the Sponsor. 
6.1
Description of Study Drugs
In this protocol, “study drug” refers to an active ingredient or placebo being tested or used as 
a reference in the study. Study drugs used in this study are described in Table 6-1. 
Subjects meeting all randomization criteria (Section 5.3) will be randomized at Visit 4 to 
receive study drug QD (Spiriva) or BID (GP MDI or Placebo MDI) during the randomized 
Treatment Period. Instructions for reading the dose indicator for the GP MDI and 
Placebo MDI and for priming, use, and cleaning of the GP MDI and Placebo MDI are 
provided in Appendix 4 and Appendix 5, respectively. Instructions for the priming, use, and

•
All clinical drug supplies contain contents under pressure. Do not use or store near heat 
or open flame. Exposure to temperatures above 49°C (120°F) may cause bursting. Never 
throw clinical drug canisters into a fire or incinerator. Avoid spraying in eyes.
•
Albuterol MDI (Ventolin HFA) should be stored at room temperature between 20°C and 
25°C (68°F-77°F); excursions permitted from 15°C to 30°C (59°F-86°F). Store the 
inhaler with the mouthpiece down. For best results, the inhaler should be at room 
temperature before use. SHAKE WELL BEFORE EACH SPRAY. 
•
GP MDI and Placebo MDI should be stored below 25°C (77°F); excursions permitted up 
to 30°C (86°F). Do not freeze.
•
Ipratropium inhalers (Atrovent HFA) should be stored at 25°C (77°F); excursions 
permitted to 15°C to 30°C (59°F to 86°F). For optimal results, the canister should be at 
room temperature before use.
•
Spiriva Respimat inhaler (tiotropium) should be stored at 25°C (77°F); excursions 
permitted to 15°C to 30°C (59°F to 86°F). Avoid freezing. 
6.5
Instructions for Dispensing and Preparation of Study Drugs for 
Administration
Before dispensing the study drug to the subject, authorized study staff must confirm the 
identifier given by the IWRS and the component identification number written on the label 
are the same. To document dispensing of the study drug, the authorized study staff will write 
the subject number and treatment visit number on each of the 2-part labels and affix the ‘tear 
off’ part of the label onto the IWRS confirmation report.
All GP MDIs and Placebo MDIs must be primed before the first use. To prime the inhaler, 
gently shake the inhaler for 5 to 10 seconds and then spray once into the air away from 
yourself and others. Wait approximately 30 seconds and repeat the process 3 more times (see 
Appendix 5 for complete instructions). 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. 
Priming should occur in a separate room from the subject treatment area.
Similarly, the Spiriva Respimat inhaler must be primed before the first use. To prime the 
inhaler, in brief, point the inhaler toward the ground and press the dose-release button. If a 
mist is seen, repeat for 3 more actuations; if a mist is not seen, follow the manufacturer’s 
instructions (see Appendix 6 for complete instructions).
Once the inhalation device is primed, the first dose (2 puffs) of study drug should be taken by 
the subject in the clinic under site personnel supervision. The date and time of the second 
puff should be recorded as the time of dose administration (ie, in iDataFax for in-clinic doses 
and in the e-Diary for at-home dosing). Subjects should be instructed to inhale 2 puffs in the 
morning and, unless randomized to Spiriva Respimat, 2 puffs in the evening approximately 
12 hours apart. The timing of the morning administration should match ±1 hour of in-clinic 
study drug administration.

Refer to Appendix 5 for additional instructions on the administration and cleaning of the GP 
MDI and Placebo MDI, and to Appendix 6 for instructions on the administration and 
cleaning of the Spiriva Respimat inhaler. Instructions for the albuterol MDI and ipratropium 
inhaler are provided in Appendix 7 and Appendix 8, respectively.
6.6
Emergency Unblinding
The Investigator or designee 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.
Emergency unblinding of study drug, for a given subject, must be done utilizing the IWRS as 
a study treatment disclosure envelope will not be provided with the clinical supplies.
Whenever possible, the Investigator should first discuss options with the Sponsor’s Medical 
Monitor or other appropriate study personnel from the Sponsor before unblinding the 
subject’s treatment assignment. If this is impractical, the Investigator must notify the Sponsor 
as soon as possible, but without revealing the treatment assignment of the unblinded subject, 
unless that information is important for the safety of other subjects currently enrolled in the 
study.
If the Investigator contacts IWRS to unblind a subject, s/he must provide the requested 
subject identifying information and confirm the necessity to unblind treatment. The date and 
reason for the unblinding must be recorded in the appropriate eCRF.
6.7
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 study personnel have access. Clinical supplies should be 
dispensed only in accordance with the protocol.
The Investigator or designee is responsible for keeping accurate records of the clinical 
supplies received from the Sponsor, the amount dispensed to and returned by the subject, and 
the amount remaining at the conclusion of the study. Study drug should be handled in 
accordance with Good Pharmacy Practices (eg, gloves should always be worn by study 
personnel if directly handling study drug that is returned). The Sponsor’s Medical Monitor or 
designee 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 the Sponsor.
Sites should check with the Sponsor representative for appropriate documentation that needs 
to be completed for drug accountability.

The Investigator or designated study personnel 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 
Sponsor’s Medical Monitor or designee.
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 the Sponsor or 
designee. Used study drug must be stored separately from unused study drug.
All product complaints (including device malfunctions) must be reported to the Sponsor or 
the Sponsor’s representative using the Product Complaints Form provided in each site’s 
regulatory binder. The Sponsor or their representatives will contact the site to evaluate the 
nature of the complaint and determine if further action is needed.

STUDY PROCEDURES
A schedule of events for all study assessments is provided in Table 8-1. A detailed visit 
schedule for all pre- and post-dose assessments is described in Table 8-2. A summary of 
24-hour Holter monitoring sub-study procedures is in Table 8-3.

Efficacy Assessments
7.1.1
Pulmonary Function Tests
7.1.1.1
Spirometry Standardization
All pulmonary function tests (PFTs) including FEV1, forced vital capacity, and forced 
expiratory flow in the midpoint as defined in ATS/ERS guidelines will be performed in 
accordance with ATS criteria (Appendix 2; Miller 2005) and will be assessed using a 
spirometer that meets or exceeds minimum performance recommendations of the ATS 
(Appendix 3).
To standardize spirometry, all sites will be provided with identical spirometry systems 
 with 
customized, study-specific software. Every effort will be made to provide all sites with 
standardized spirometry equipment. The volume accuracy of the spirometer is to be checked 
daily with appropriate documentation in a calibration log prior to the conduct of PFTs on 
each test day.
The volume accuracy of the spirometer is checked 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 not be used beyond the expiry date. 
Required accuracy is ±3% (ie, 3.09 L to 2.91 L; ATS/ERS). The results will be printed and 
maintained in a calibration log, which will be monitored for compliance during the 
monitoring visits (see Appendix 2). 
All study staff responsible for performing PFTs will receive standardized training at the 
Investigator Meeting. All technicians are required to demonstrate proficiency in the use of 
the equipment and the ability to perform technically acceptable PFTs (ATS criteria) prior to 
performing PFTs on study subjects (Miller 2005). After each test is performed, the 
spirometry software will provide immediate feedback to the technician indicating whether 
the effort meets ATS acceptability and repeatability standards (Miller 2005). All PFTs will 
be stored electronically. After completion of testing, the study staff will electronically 
transmit the spirometry measurements for centralized quality assurance review 
 
 Feedback on the quality of the measurements will be provided to the 
investigational site and to the Sponsor or designee for central data management.
As spirometry results are primary and secondary efficacy endpoints for this study, it is 
important for the medication withholding conventions and timing of spirometry to be 
consistently managed throughout the study (Section 8.1).

7.1.1.2
Spirometry Schedule
Spirometry collection is briefly outlined below. For exact spirometry collection and 
specifications, please refer to Table 8-1 and Section 8.
•
Visit 1: 
-
Spirometry, including reversibility to albuterol, will be performed at Visit 1 only if 
the subject did not take their morning doses of inhaled asthma maintenance 
medications and if albuterol was not administered within 6 hours. If the subject has 
not withheld their dose(s) of regular asthma medications (Section 8.1) or albuterol, 
Visit 1 should be rescheduled no sooner than the following day.
-
Spirometry will be conducted at 60 and 30 minutes prior to bronchodilator (albuterol) 
administration and 30 minutes post-bronchodilator (Section 7.1.1.3). If subjects are 
not reversible to albuterol at 30 minutes post-dose, the post-dose PFTs can be 
repeated at 60 minutes post-dose. 
-
The average of the 2 pre-bronchodilator FEV1 values will be calculated to determine 
if the subject meets the inclusion criterion (ie, FEV1 >40% and <85% of predicted 
normal value for subjects 18 to 80 years of age or FEV1 >40% and <90% of predicted 
normal value for subjects 12 to <18 years of age).
-
FEV1 repeatability must be demonstrated at one of the pre-dose measurements.
•
Visit 2:
-
Spirometry will only be conducted in those subjects who did not demonstrate 
reversibility to albuterol at Visit 1.
-
Subjects who did not meet albuterol reversibility criteria at Visit 1 must meet these 
criteria at Visit 2.
-
When spirometry is conducted at Visit 2, the procedures will be the same as those 
described above for Visit 1 (eg, FEV1 inclusion criterion must be met). 
•
Visit 3: spirometry will be conducted 60 and 30 minutes prior to ipratropium 
administration and 30 minutes post-ipratropium (Section 7.1.1.3).
•
At Visits 4, 7, and 10/Final Visit or the Treatment Discontinuation Visit: spirometry will 
be conducted 60 minutes and 30 minutes prior to study drug and ICS/LABA 
administration and 15 minutes, 30 minutes, and 1, 2, and 4 hours post-dosing with study 
drug and ICS/LABA (if a subject discontinues taking study drug but agrees to continue in 
the study and complete all remaining study visits, the subject’s usual inhaled asthma 
maintenance medication(s) will be administered for spirometry testing instead of study 
drug). At Visit 4, the average of the 2 pre-dose FEV1 values will be calculated to 
determine if the subject meets the inclusion criterion.
•
At Visits 5, 6, 8, and 9: spirometry will be conducted 60 minutes and 30 minutes prior to 
study drug and ICS/LABA administration.
Subjects will be required to return to the clinic at approximately the same time of day for all 
treatment visits. All in-clinic dosing must occur prior to 10 am with consistent in-clinic dose 

Glycopyrronium Inhalation Aerosol

timing throughout the randomized Treatment Period; visits must be planned accordingly 
(Section 8.1). The subjects will be required to remain at the clinic until completion of all 
protocol-defined assessments.
7.1.1.3
Reversibility to Albuterol and Ipratropium
Reversibility to albuterol will be evaluated for subject qualification purposes, and 
reversibility criteria must be met at either Visit 1 or Visit 2 (Section 5.1). If reversibility 
criteria are met at Visit 1, reversibility testing will not be repeated at Visit 2. If reversibility 
criteria are not met at Visit 1, subjects may continue to Visit 2; however, reversibility criteria 
must be met at Visit 1 or Visit 2 to continue to Visit 3.
Reversibility to ipratropium will be evaluated at Visit 3 for characterization and 
randomization stratification purposes.
The procedures for determining reversibility to albuterol and ipratropium are as follows:
1. Determine if morning doses of all maintenance asthma medications were withheld and 
that short-acting bronchodilators were not administered within 6 hours of testing
2. Perform prebronchodilator PFTs at 60 and 30 minutes prior to administration of 
bronchodilator
3. Administer 4 puffs of albuterol (Visit 1 and, if needed, Visit 2) or 4 puffs ipratropium 
(Visit 3).
4. Perform postbronchodilator PFTs 30 minutes after the administration of either albuterol 
or ipratropium (as appropriate per visit). If subjects are not reversible to albuterol at 
30 minutes, the post-dose PFT can be repeated at 60 minutes post-dose. Repeat 
spirometry at 60 minutes post-dose is not necessary for reversibility testing to 
ipratropium.
Reversibility will be a comparison of the average best FEV1 effort obtained at 60 and 
30 minutes prebronchodilator to the best FEV1 effort obtained at 30 minutes (or up to 
60 minutes, if repeated for albuterol) postbronchodilator following administration of either 
albuterol or ipratropium. A subject is considered reversible to albuterol if the improvement in 
FEV1 at 30 minutes (or up to 60 minutes) post-albuterol is ≥12% and ≥200 mL.
7.1.2
Subject’s eDiary Data Collection
At Visit 1, subjects will be trained on and receive their eDiary. Prior to issuing the eDiary to 
the subject, site personnel are responsible for programming the eDiary and training subjects 
on its use. Subjects will enter the following information into the eDiary BID beginning with 
Visit 1 and for the duration of the study during both Screening and Treatment Periods: 
daytime and nighttime asthma symptom scores, and use of rescue albuterol. During the 
Screening Period, time of ICS/LABA administration will also be entered (this will be QD for 
ICS/LABAs that are only administered QD and BID otherwise); ipratropium use, if 
applicable, will be recorded as a concomitant medication. During the Treatment Period, time 

Glycopyrronium Inhalation Aerosol

Page 50 of 163
of study drug administration will also be entered; time of ICS/LABA administration will then 
be recorded as a concomitant medication.
7.1.2.1
eDiary Compliance Requirement
Between Visits 1 and 4, subjects will be required to demonstrate acceptable eDiary 
collections and compliance in order to be eligible for randomization. Subject participation 
may be terminated at any time during the study for the following reasons:
•
Subjects who are unable to meet the compliance requirement (≥70% subject completion 
of eDiary assessments) in the 7 days prior to Visit 4 will be considered a screen failure
•
Chronic failure in the judgment of the Investigator (eg. noncompliance with the eDiary), 
despite documentation at the site of repeated efforts to reinforce compliance. As defined 
for this study, compliance requires ≥70% subject completion of eDiary assessments for 
the duration of the study. The Sponsor may also instruct a site to discontinue a subject 
based on consistent noncompliance.
7.1.2.2
Rescue Medication Use
Use of rescue medication will be recorded in the eDiary each morning (reflecting nighttime 
albuterol use) and each evening (reflecting daytime albuterol use). The subject will record the 
total number of “puffs” of albuterol used over the time period as the number of actuations on 
the canister. For example, when rescue medication is required and 2 actuations are inhaled, 
this should be recorded as 2 “puffs.” If the subject requires 4 actuations, this should be 
recorded as 4 “puffs.”
7.1.2.3
PEFR
The PEFR is to be assessed using the Sponsor-provided PEFR meter, which will be paired 
with the eDiary via Bluetooth. Subjects will be dispensed and trained on the device at Visit 1. 
The eDiary will remind the subject BID when it is time to obtain their peak flow. Once the 
subject has completed the peak flow assessment, the data will be automatically transmitted 
from the PEFR to the eDiary. The best (highest) of 3 PEFR efforts BID will be captured in 
the eDiary.
Subjects will complete the PEFR maneuver at home once in the morning and once in the 
evening before dosing with ICS/LABA (and ipratropium, if applicable) during the Screening 
Period, and once in the morning and once in the evening before dosing with study drug and 
ICS/LABA during the Treatment Period. In addition, PEFR should be measured before use 
of rescue albuterol. 
On the morning of all clinic visits, PEFR will be assessed at home prior to coming to the 
clinic. Subjects do not need to bring their peak flow meter to clinic visits, except to their final 
visit.

Page 51 of 163
At Visit 4, a PEFR stability limit will be automatically calculated by the eDiary. The stability 
limit is defined as the average of the available morning PEFR eDiary recordings during at 
least 4 of the last 7 days before Visit 4 (ie, the baseline PEFR), multiplied by 0.8. The PEFR 
stability limit will be used to help identify moderate asthma exacerbation as described in 
Section 7.1.3.
7.1.2.4
Asthma Symptoms
The subject will record their asthma symptom scores in the eDiary each morning (reflecting 
nighttime symptoms) and each evening (reflecting daytime symptoms). This symptom 
assessment should occur before determining PEFR and before administration of any 
medications during the Screening Period or randomized Treatment Period.
Subjects will assess the symptoms of cough, wheeze, shortness of breath, and chest tightness 
and enter a single score that is inclusive of all symptoms for their daytime and nighttime 
symptom scores. Symptom scores will be used to help identify moderate asthma 
exacerbations as described in Section 7.1.3.
The following symptoms will be assessed:
Daytime Symptom Score (determined in the evening)
0=No symptoms during the day
1=Symptoms for 1 short period during the day
2=Symptoms for 2 or more short periods during the day
3=Symptoms for most of the day that did not affect my normal daily activities
4=Symptoms for most of the day that did affect my normal daily activities
5=Symptoms so severe that I could not go to work or perform normal daily activities
Nighttime Symptom Score (determined in the morning)
0=No symptoms during the night
1=Symptoms causing me to wake once (or wake early)
2=Symptoms causing me to wake twice or more (including waking early)
3=Symptoms causing me to be awake for most of the night
4=Symptoms so severe that I did not sleep at all
On clinic visit mornings, the nighttime symptom score will be determined and recorded at 
home prior to the clinic visit.

7.1.2.5
Study Drug and Other Study Medication Compliance
During the Screening Period, subjects will record the times of ICS/LABA dosing in the
eDiary for practice. Rescue medication (albuterol) use will also be recorded as described in 
Section 7.1.2.2. 
During the Treatment Period, subjects will record the times of study drug dosing (morning 
and evening for BID treatments, morning only for the QD treatment) in the eDiary, except on 
the mornings of in-clinic dosing. 
ICS/LABA dosing during the Screening Period and during the Treatment Period will be 
recorded as concomitant medications.
Study drug compliance will be checked at all visits. Any issues identified will be documented 
in the appropriate study file and reinstruction will be completed as necessary.
7.1.2.6
Symptom Worsening Assessment and eDiary Alert System
The eDiary will be programmed to monitor for signs of a potential asthma exacerbation by 
monitoring decreases from baseline in morning or evening PEFR, increases from baseline in 
the number of puffs of albuterol used per day, and/or increases in daytime or nighttime 
asthma symptom scores (Section 7.1.3). If any of these parameters meet the pre-defined 
thresholds for a moderate asthma exacerbation (Table 7-1), the eDiary will generate an alert 
to the subject and the clinical site. This alert is intended to generate a contact between the 
subject and the Investigator to assess the status of the subject’s asthma.
7.1.3
Asthma Exacerbations
7.1.3.1
Definitions and Treatments
The definitions of mild, moderate, and severe asthma exacerbations to be used in this study 
are shown in Table 7-1. These definitions are based on the ATS/ERS Statement “Asthma 
Control and Exacerbations, Standardizing Endpoints for Clinical Asthma Trials and Clinical 
Practice” (Reddel 2009).

Definition
Criteria for Study Drug 
Discontinuationc
Severea
Use of systemic corticosteroids (tablets, suspension, 
or injection) for at least 3 days OR a hospitalization or 
ER visit because of asthma
There are 2 criteria for 
discontinuing study drug based on 
asthma exacerbations 
(Section 5.9.1):
•
Inpatient hospitalization
•
Requirement for >2 courses of 
oral corticosteroids to treat an 
exacerbation during the course 
of the study
Moderateb
A deterioration of asthma requiring a new or 
increased dose of ICS for at least 3 days.
Deterioration of asthma is defined by the occurrence 
of 1 or more of the following for ≥2 consecutive days: 
•
PEFR: a decline of ≥20% from baseline 
(see Section 7.1.2.3 for baseline PEFR stability 
limit calculation)
•
Rescue albuterol use: >4 puffs/day and 
≥2×baseline
•
Symptoms: nighttime score that is >baseline and 
≥2 OR a daytime score that is >baseline and ≥3
Mild
A deterioration of asthma (as defined above) 
•
Not requiring treatment OR 
•
Requiring treatment with a systemic 
corticosteroid or a new or increased dose of ICS 
for <3 days
Abbreviation: ER=emergency room.
a
Subjects who have died because of asthma will be considered to have had a severe asthma exacerbation 
regardless of whether they received systemic corticosteroids or were hospitalized.
b
Will be captured via the eDiary.
c
For subjects who discontinue study drug, the Investigator will place subjects on appropriate asthma 
medications and the subjects will be encouraged to stay in the study and complete all remaining study visits 
and procedures.
In cases where the subject meets the criteria for a moderate or severe asthma exacerbation, 
the Investigator or designee will enter the information into the eCRF on the asthma 
exacerbation page (refer to Section 7.1.3.3). A mild exacerbation will be captured by the 
eDiary.
The recommended treatment for a moderate asthma exacerbation is a short course (5-7 days) 
of an increased dose of ICS or an additional ICS as outlined below, to help avoid progression 
to a severe exacerbation:
•
Budesonide 400 ∀g BID for 5 to 7 days

Glycopyrronium Inhalation Aerosol

Clinical Study Protocol: PT001102-04
Version 5.0
Confidential and Proprietary
Page 54 of 163
Note: Each actuation of Pulmicort Turbuhaler 200 ∀g delivers 160 ∀g budesonide from the 
mouthpiece, which is the same amount as delivered by an actuation of Pulmicort Flexhaler 
180 ∀g.
For an individual subject, the same increased dose of ICS or additional ICS should be used 
throughout the study when possible.
The recommended (GINA 2017) treatment for a severe asthma exacerbation is a short course 
of oral corticosteroids as outlined below:
•
Prednisolone (1 mg/kg/day up to 50 mg for adults and adolescents) QD (preferably in the 
morning) for 5 to 7 days
•
Tapering the prednisolone dose is not needed if the treatment has been given for 
<2 weeks
Additional information about treatment of asthma exacerbations is provided in 
Section 5.7.2.2.2.
7.1.3.2
Onset and Duration of Asthma Exacerbations
For a severe asthma exacerbation, the start date is defined as the start date of prescribed 
treatment with a systemic corticosteroid or the date of ER visit or hospitalization for asthma. 
The stop date is defined as the last day on which systemic corticosteroids were used, or the 
discharge date from the ER or hospital for asthma, whichever is later.
For a moderate asthma exacerbation, the start date is defined as the first day of the increased 
dose of ICS or new ICS treatment (for example, adding inhaled budesonide) and the end date 
is defined as the last day of this treatment.
For a mild asthma exacerbation, the start date is defined as the first day of 2 consecutive days 
of deterioration and the end date is defined as the first day the subject no longer meets the 
deterioration criteria OR the last day of treatment, whichever is later. Treatment must be for 
less than 3 days to meet the criteria for a mild exacerbation.
In order to ensure that the same event is not counted twice, consecutive exacerbations with 
start and stop dates ≤7 days apart will be considered to be the same event of the highest 
severity.  Any exceptions and clarifications to this rule will be provided in detail in the
statistical analysis plan.
7.1.3.3
Approach for Capturing Asthma Exacerbations
Asthma exacerbations occurring prior to Visit 1 will be considered part of the subject’s 
medical history and will be captured in the medical history eCRF.

Glycopyrronium Inhalation Aerosol
Pearl Therapeutics, Inc.
Clinical Study Protocol: PT001102-04
Version 5.0
Confidential and Proprietary
Page 55 of 163
All moderate and severe asthma exacerbations occurring after Visit 4 must be captured on the 
asthma exacerbation eCRF page. Mild exacerbations will be identified and captured by the 
eDiary alert system. 
Asthma exacerbations will be considered expected study endpoints and will not be reported 
as AEs unless they meet the criteria for a serious adverse event (SAE). The start date for an 
SAE of severe asthma exacerbation should be the start date of systemic corticosteroids or the 
date of ER visit or hospitalization for asthma as stated in Section 7.1.3.2.
7.1.4
Subject Questionnaires
Subject questionnaires (ACQ and the AQLQ +12) will be completed on site utilizing study-
supplied electronic questionnaire devices (not the subject’s eDiary) at specified visits 
throughout the study.
7.1.4.1
ACQ 
The ACQ will be completed at Visits 2 and 4 through 10/Final Visit, or if the subject 
withdraws consent/discontinues study drug, at the Treatment Discontinuation or Study 
Withdrawal Visit, before any other study procedures are performed.
The ACQ (Appendix 9; Juniper 1999a) was developed to measure asthma control and has 
been fully validated for use in adults and in children 6 to 17 years of age. International 
guidelines for the treatment of asthma have identified that the primary clinical goal of asthma 
management is to optimize asthma control (minimization of symptoms, activity limitation, 
bronchoconstriction, and rescue bronchodilator use) and thus reduce the risk of life-
threatening exacerbations and long-term morbidity. The ACQ was developed to meet these 
criteria by measuring both the adequacy of asthma control and change in asthma control, 
which occurs either spontaneously or as a result of treatment.
The ACQ, comprising 7 questions, is completed in the clinic and requires subjects to recall 
their experiences during the previous week (7 days) prior to the study visit. The ACQ-5, -6, 
and -7 (questions 1-5, 1-6, and 1-7, respectively) have all been validated. The ACQ-5 
measures 5 symptoms (woken at night by symptoms, wake in the morning with symptoms, 
limitation of daily activities, shortness of breath, and wheeze); the ACQ-6 is these symptom 
measurements plus daily rescue medication use as recalled by the subject; and the ACQ-7 is 
the ACQ-6 plus airway caliber as measured by pre-bronchodilator FEV1 percent predicted.
Each question is scored on a 7-point scale (generally, 0=no impairment, 6=maximum 
impairment), the questions are equally weighted, and the ACQ score is the mean of the item 
responses and therefore ranges from 0 (totally controlled) to 6 (severely uncontrolled).
7.1.4.2
AQLQ +12
The AQLQ +12 will be completed at Visits 4 through 10/Final Visit, or at the Treatment 
Discontinuation or Study Withdrawal Visit, after the ACQ and before any other study 
procedures are performed.

Glycopyrronium Inhalation Aerosol
Pearl Therapeutics, Inc.
Clinical Study Protocol: PT001102-04
Version 5.0
Confidential and Proprietary
Page 56 of 163
The AQLQ +12 is a 32-item validated subject-administered questionnaire that was developed 
to measure the functional problems (physical, emotional, social and occupational) that are 
most troublesome to adults (≥18 years of age) and adolescents (12 to 17 years of age) with 
asthma (Juniper 2005, Juniper 1999b, Juniper 1994, Juniper 1993, Juniper 1992). The 
32 questions in the AQLQ +12 are in 4 domains (symptoms, activity limitation, emotional 
function, and environmental stimuli). All 4 domains contain standard specific questions 
relating to each domain.
Subjects are asked to think about how they have been during the previous 2 weeks and to 
respond to each of the 32 questions on a 7-point scale (7=no impairment to 1=severe 
impairment). The overall AQLQ +12 score is the mean of all 32 responses and the individual 
domain scores are the means of the items in those domains. A change in score of 0.5 on the 
7-point scale is the smallest change that can be considered clinically important, known as the 
minimal clinically important difference. Additional information about the AQLQ +12 is 
provided in Appendix 10.
7.1.5
FENO
The FENO will be collected at Visits 2, 4, 5, 7, and 10/Final Visit, or at the Treatment 
Discontinuation or Study Withdrawal Visit, prior to spirometry. The procedure is described 
in Appendix 11.
Measurement of FENO is a noninvasive and established clinical biomarker for airway 
inflammation that is recommended by the ATS to monitor eosinophilic airway inflammation 
in subjects with asthma (Dweik 2011). Each site will be provided with a FENO device (Niox 
Vero® [Circassia Pharmaceuticals Inc., Chicago, Illinois, US]) and all required accessories 
(eg, test kits) and receive training on its use and care (Appendix 11). Clinically meaningful 
increases and decreases in FENO are defined in Section 9.5.3.9.
7.2
Safety Assessments
Safety assessments for this study are AEs, physical examinations, vital signs, 12-lead ECGs, 
24-hour Holter monitoring, and clinical laboratory tests.
7.2.1
Medical/Surgical/Asthma Exacerbation History and Physical Examination
Medical history will be collected at Visit 1 and updated during the Screening Period, if 
necessary. The number of asthma exacerbations requiring systemic corticosteroids, 
emergency room visits, and/or hospitalizations within the previous 12 months will be 
collected at Visit 1.
A complete physical examination will be performed at Visits 1 and 10/Final Visit. The 
complete physical examination will include the following:
•
Weight, general appearance, skin, head, eyes, ears, nose, throat, neck (including thyroid), 
lymph nodes, chest, heart, abdomen, extremities, and nervous system

•
Height will be measured at Visit 1 for subjects who have had their 18th birthday and at 
Visits 1, 4, 5, 7, and 10 for subjects 12 years of age up to and including their 18th
birthday, at the visit.
7.2.2
Vital Sign Measurements
Vital sign measurements (HR, SBP, and diastolic blood pressure [DBP]) will be obtained 
after the subject has rested for at least 5 minutes in either the supine or seated position. A 
single measurement of vital signs will be obtained as follows: 
•
Visit 1: before PFTs
•
Visit 2: before pre-bronchodilator (albuterol) PFT for reversibility testing
•
Visit 3: before pre-bronchodilator (ipratropium) PFT for reversibility testing
•
Visits 4, 7, and 10/Final Visit: approximately 60 minutes pre-dose and 4 hours post-dose
•
Visits 5, 6, 8, and 9: approximately 60 minutes pre-dose
For subjects who discontinue study drug or withdraw consent, a single measurement of vital 
signs will be obtained at the Treatment Discontinuation Visit or Study Withdrawal Visit, 
respectively.
7.2.3
12-Lead ECG
To standardize ECG collection, all sites will be provided with identical ECG equipment 
 
 with customized study-specific software.
All study staff responsible for performing ECG collection will receive detailed training at the 
Investigator Meeting as well as site phone training sessions. Each site is required to 
demonstrate proficiency in the use of the equipment and the ability to perform technically 
acceptable ECGs prior to performing on study subjects. After each test has been performed, 
the ECG data will be transmitted electronically for centralized quality assurance review 
 Feedback on the quality of the ECGs will be provided to the 
investigational site via a site qualification form.
A single ECG will be obtained as follows:
•
At Visit 1
•
At Visits 4, 5, 7, and 10/Final Visit within 60 minutes prior to dosing 
For subjects who discontinue study drug or withdraw consent, a single ECG will be obtained 
at the Treatment Discontinuation or Study Withdrawal Visit.

The ECG parameters to be assessed include HR, PR interval, QRS axis, QRS interval, and 
QT/QTcF interval. The QT intervals and calculated QTcF intervals will be reviewed and 
checked for gross inaccuracies by the Investigator or designated ECG reviewer. Subjects who 
experience a change from their baseline ECG may need to discontinue study drug per criteria 
specified in Section 5.9.1.
7.2.4
Holter Monitoring: 24-Hour Continuous Electrocardiography
The following information applies only to those subjects participating in the 24-hour Holter 
monitoring sub-study.
Continuous Holter monitoring will be conducted over 24 hours at Visit 3 and at Visit 7. 
Holter monitor recordings are to be initiated in the morning at approximately the same time 
(±2 hours) for these visits and 15 to 30 minutes before administration of the morning dose of 
ICS/LABA and, at Visit 7, study drug. Holter monitor procedures are summarized in 
Table 8-3.
Continuous Holter monitor recording will be collected for 24 hours. Holter monitor 
recordings must contain a minimum of 18 hours of acceptable quality recording in a 24-hour 
period to be deemed a successful Holter monitor assessment.
The designated service provider for Holter monitoring will be 
 
All Holter monitor recordings will be assessed for cardiac arrhythmias by an independent 
cardiologist appointed by 
.
7.2.4.1
Visit 3 Holter Monitoring Procedures
The Visit 3 (screening/baseline) Holter monitoring will be initiated following reversibility 
testing to ipratropium and 15 to 30 minutes before administration of the morning dose of 
ICS/LABA.
When the subject returns to the clinic the following day, the quality of the Holter monitor 
recordings will be assessed at the site. If the first Holter monitoring attempt is not successful 
(ie, <18 hours of acceptable quality recording), the Holter monitor will be reconnected for 
another 24 hours using a new Holter monitor hook-up kit. The subject will be instructed to 
continue his/her medications as per study protocol. The subject will return the following day 
for removal of the Holter monitor. This second attempt should be scheduled so that the 
Holter monitoring will be completed at least 24 hours before administration of the morning 
dose of study drug and ICS/LABA at Visit 4.
If the Holter monitoring recording remains inadequate on the second attempt, the subject will 
not be eligible to participate in the Holter monitoring sub-study, but DOES NOT need to be 
excluded from the full study. If clinically significant findings (as defined in Holter monitor 
exclusion criteria [Section 5.5]) are noted on any of the Holter monitor recordings, there will 
be no further attempts; the subject will be considered a screen failure and will not be eligible 
to enroll in the full study.

7.2.4.2
Visit 7 Holter Monitoring Procedures
At Visit 7, Holter monitoring will be initiated 15 to 30 minutes before administration of the 
morning dose of study drug and ICS/LABA in the clinic. Subjects will be instructed to return 
to the clinic the following day for removal of the Holter monitor.
When the subject returns to the clinic the following day, the quality of the Holter monitor 
recordings will be assessed at the site. If the first Holter monitoring attempt is not successful 
(ie, <18 hours of acceptable quality recording), the Holter monitor will be reconnected for 
another 24 hours using a new Holter monitor hook-up kit. The subject will be instructed to 
continue his/her medications as per study protocol. The subject will return the following day 
for removal of the Holter monitor. This second attempt should be scheduled so that the 
Holter monitoring will be placed on or before Visit 8. 
If the Holter monitoring recording remains inadequate on the second attempt, there will be no 
further attempts. 
7.2.4.3
Data for Analysis
Data for analysis will include the following:
•
General trends including HR
•
Hourly rhythm assessments
•
Ventricular ectopy summary
•
Ventricular run summary
•

•
Any other clinically relevant arrhythmias, including atrial fibrillation and pronounced 
bradycardia
Manual summary interpretation of the data will be sent as a report to the site and to the 
Sponsor.
7.2.5
Clinical Laboratory Tests
Subjects will be in a seated or supine position during blood collection. 
Clinical safety laboratory tests will be analyzed by a central laboratory according to 
standardized, validated assays with the exception of urine pregnancy tests. The laboratory 
will supply detailed procedures for the preparation and collection of blood and urine samples 
along with all containers needed for their collection. Urine pregnancy tests will be performed 
at the clinical site using a commercially available test product.

AEs
7.3.1
Performing AE Assessments
The Investigator is responsible for promptly documenting and reporting all AEs observed 
during the study in the subject’s eCRF and on the AE reporting form. If the AE is 
unexpected, the Investigator should report the AE immediately to the Sponsor. In addition, 
certain AEs are classified as ‘serious’ (as described in Section 7.3.9) and must be reported no 
later than 24 hours after the Investigator recognizes/classifies the event as an SAE to the 
Sponsor or its designee.
In the case of SAEs, after discussing the details of the event, the Investigator and the Medical 
Monitor may discontinue the subject from study drug.
7.3.2
AE Definitions
The following definitions of terms are guided by the International Conference on 
Harmonisation (ICH) Technical Requirements for Registration of Pharmaceuticals for 
Human Use, the US Code of Federal Regulations (21 CFR 312.32) and European Union 
Directive 2001/83/EC and are included herein.
An AE is any untoward medical occurrence associated with the use of a drug in humans, 
whether or not considered drug related. An AE (also referred to as an adverse experience) 
can be any unfavorable and unintended sign (eg, an abnormal laboratory finding), symptom, 
or disease temporally associated with the use of a drug, without any judgment about 
causality. An 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 the following:
•
Any symptom or condition not previously reported by the subject (medical history)
•
An exacerbation of a pre-existing symptom or condition
•
A significant increase in frequency or intensity of a pre-existing episodic event or 
condition
•
A drug interaction
•
A condition first detected or diagnosed after study drug administration even though it 
may have been present prior to the start of the study
An AE does not include the following:
•
Medical or surgical procedures (eg, surgery, endoscopy, tooth extraction, blood 
transfusion); the condition that leads to the procedure is an AE (eg, bleeding esophageal 
varices, dental caries)

Glycopyrronium Inhalation Aerosol
Pearl Therapeutics, Inc.

Version 5.0
Confidential and Proprietary
Page 63 of 163
•
Overdose of either study drug or concurrent medication without any clinical signs or 
symptoms
•
Abnormal laboratory values that are not clinically significant; if accompanied by 
signs/symptoms, the signs or symptoms are considered an AE
7.3.3
Pre-Randomization AEs
Any AE occurring from the time the subject signs informed consent until the subject is 
randomized will be summarized as medical history and not as an AE unless the event meets 
the definition of an SAE as defined in Section 7.3.9.
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 to Study Drug
The Investigator will assess causal relationship between investigational product and each AE, 
and answer yes/no to the question, “Do you consider that there is a reasonable possibility that 
the event may have been caused by the investigational product?”
For SAEs, causal relationship will also be assessed for other medication and study 
procedures. Note that for SAEs that could be associated with any study procedure, the causal 
relationship is implied as ‘yes’.
7.3.6
Asthma Exacerbations and Associated Symptoms of Asthma
Asthma exacerbations may occur as a manifestation of asthma despite using standardized 
drug treatment or treatment(s) with combination therapies. As a result, the Sponsor has 
classified an asthma exacerbation as a protocol-specified expected event, and it is not to be 
reported as an AE unless considered an SAE. Moderate and severe asthma exacerbations 
must be captured on the asthma exacerbations eCRF; mild asthma exacerbations will be 
captured by the eDiary.

Version 5.0
Confidential and Proprietary
Page 64 of 163
Since asthma exacerbations are expected events in this study, any individual case safety 
reports received related to an exacerbation of asthma will not be submitted on an expedited 
basis as a suspected unexpected serious adverse reaction unless further assessment is required 
by the Sponsor.
Associated symptoms of asthma (eg, wheeze, breathlessness, cough), the disease under study, 
will not be reported as AEs, unless considered an SAE. 
7.3.7
AEs of Special Interest
Certain AEs have been identified as adverse events of special interest (AESIs) due to the 
class of drugs being studied. These AEs will be captured through spontaneous reports, and 
the reporting of these AESIs will be described in the statistical analysis plan (SAP). Some 
events are described below but this is not a comprehensive list of all AESIs.
7.3.7.1
LAMA Effects
Known effects of LAMAs include dry mouth, cardiovascular effects, ocular disorders, 
urinary retention, and gastrointestinal disorders.
7.3.7.2
Paradoxical Bronchospasm
Monitoring for paradoxical bronchospasm will occur at Visits 4, 5, 7, and 10/Final Visit at 
15 and 30 minutes post-dose. 
In this study, paradoxical bronchospasm is defined as a reduction in FEV1 of >20% from 
baseline with associated symptoms of wheezing, shortness of breath, or cough that occur 
within 30 minutes post-dosing. Baseline is defined as the mean of the FEV1 values obtained 
60 and 30 minutes prior to study drug and ICS/LABA administration at that visit. 
7.3.8
Clinical Laboratory AEs
Many laboratory abnormalities observed during the course of a study will be included under 
a reported AE describing a clinical syndrome (eg, elevated blood urea nitrogen and creatinine 
in the setting of an AE of renal failure, or decreased hemoglobin in a case of bleeding 
esophageal varices). 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 the following:
•
A laboratory abnormality that leads to a dose-limiting toxicity (eg, an abnormality that 
results in study drug dose suspension or treatment 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.

An AE is considered ‘serious’ if, in the view of the Investigator or Sponsor, it results in any 
of the following outcomes:
•
Death
•
A life-threatening AE
•
In-patient hospitalization or prolongation of existing hospitalization
•
A persistent or significant incapacity or substantial disruption of the ability to conduct 
normal life functions
•
A congenital anomaly/birth defect
Important medical events that may not result in death, be life threatening, or require 
hospitalization may be considered serious when, based upon appropriate judgment, they 
jeopardize the subject or require medical or surgical intervention to prevent one of the 
outcomes listed in the definition. Examples of such medical events include allergic 
bronchospasm requiring intensive treatment in an emergency room or at home, blood 
dyscrasias or convulsions that do not result in subject hospitalization, or the development of 
drug dependency or drug abuse.
Hospitalization for a pre-existing condition (including elective procedures) that has not 
worsened does not constitute an SAE.
An AE or suspected adverse reaction is considered life threatening if, in the view of the 
Investigator or Sponsor, its occurrence places the subject 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 
IB or is not listed at the specificity or severity that has been observed.
7.3.9.1
Reporting SAEs
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 the Sponsor’s Pharmacovigilance Department or designee. All SAEs 
must be reported to the Sponsor Pharmacovigilance Department or designee no later than 
24 hours after the Investigator recognizes/classifies the event as an SAE. All SAEs should be 
documented and reported using the eCRF. At a minimum, a description of the event and the 

Glycopyrronium Inhalation Aerosol
Pearl Therapeutics, Inc.
Clinical Study Protocol: PT001102-04
Version 5.0
Confidential and Proprietary
Page 66 of 163
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 an SAE to the Sponsor’s 
Pharmacovigilance Department or designee within 2 working days after receiving the 
information. Follow-up information will be a detailed written report that may include copies 
of hospital records, case reports, autopsy reports, and other pertinent documents.
For subjects who complete the entire study, all AEs/SAEs will be collected through 14 
(+2) days after the last dose of study drug via a follow-up telephone call (see Section 8.11).
For subjects who discontinue randomized study drug but are planning to continue study 
participation (ie, planning to complete all remaining study visits and procedures), see 
Section 8.9.1, Treatment Discontinuation.
For subjects who withdraw from the study, see Section 8.9.2, Study Withdrawal.
Post-treatment SAEs following the last dose of study drug must be reported to the Sponsor’s 
Pharmacovigilance Department as described in Section 7.3.9.3.
The Investigator is responsible for continuing to report any new or relevant follow-up 
information that s/he learns about the SAE.
7.3.9.2
Supplemental Investigations of SAEs
The Investigator and supporting personnel responsible for subject care should discuss with 
the Sponsor Medical Monitor or designee any need for supplemental investigations of SAEs. 
If additional assessments are conducted, results must be reported to the Sponsor. If a subject 
dies during study participation and if a postmortem examination is performed, a copy of the 
autopsy report should be submitted to the Sponsor.
7.3.9.3
Notification of Post-Study SAEs
Investigators are not obligated to actively follow subjects after completion of the study. 
However, if the Investigator becomes aware of a post-study SAE occurring within the 
14 days following the last dose, the SAE must be reported to the Sponsor, whether or not the 
event is attributable to study drug. All SAEs must be reported to the Sponsor no later than 
24 hours after the Investigator recognizes/classifies the event as an SAE.
7.3.9.4
Institutional Review Board/Independent Ethics Committee Notification of SAEs
The Investigator is responsible for promptly notifying her/his Institutional Review Board 
(IRB)/Independent Ethics Committee (IEC) of all SAEs, including any follow-up 
information, occurring at their site and any SAE regulatory report, including any follow-up 
reports received from the Sponsor. Documentation of IRB/IEC submission must be retained 
for each safety report. The Investigator is also responsible for notifying the Sponsor if their 
IRB/IEC requires revisions to the ICF or other measures based on its review of an SAE 
Report.

7.3.9.5
Health Authority Safety Reports
The Sponsor or its representatives will submit a safety report to the appropriate regulatory 
agencies for any suspected adverse reaction that is both serious and unexpected within the 
timeframe specified by each regulatory agency.
The Sponsor or its representatives will send copies of each submitted safety report to 
Investigators actively participating in Pearl-sponsored clinical studies. Safety reports must 
also be submitted to the appropriate IRBs/IECs as soon as possible. Documentation of 
submission to the IRB/IEC must be retained for each safety report.
7.3.10
Post-Study Follow-Up of AEs and SAEs
Any AEs/SAEs that are unresolved at the subject’s last AE assessment in the study are to be 
followed up by the Investigator for as long as medically indicated but without further 
recording in the eCRF. The Sponsor 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.
7.3.11
Overdose
An overdose is defined as any dose greater than the highest dose investigated in this study 
that results in clinical signs and symptoms. In the event of a study drug overdose, the 
Investigator should use their best clinical judgment in treating the overdose, and the 
Sponsor’s Medical Monitor should also be contacted. Investigators should refer to the 
relevant document(s) for detailed information regarding warnings, precautions, 
contraindications, AEs, and other significant data pertaining to the study drug(s) being 
administered. Such document(s) may include but are not limited to the IB for GP MDI and 
approved product labeling for open-label products.
7.3.12
Pregnancy
To ensure subject safety, each pregnancy from Visit 1 until study completion must be 
reported to the Sponsor within 24 hours of learning of its occurrence. The pregnancy should 
be followed in its entirety to ascertain outcome, including spontaneous or voluntary 
termination, details of the birth, and the presence or absence of any birth defects, congenital 
abnormalities, or maternal and/or newborn complications. Pregnancy should be recorded on a 
paper pregnancy report form and reported by the Investigator to the Sponsor’s 
Pharmacovigilance Department or designee. Pregnancy follow-up should be recorded on the 
same pregnancy paper form and should include possible relationship to the study drug in 
response to the pregnancy outcome. Any SAE experienced during pregnancy must be 
reported on the SAE report form.
7.3.13
Paternal Exposure
If a male subject's partner becomes pregnant during the course of the study, it must be 
reported to the Sponsor within 24 hours of the Investigator learning of its occurrence.

7.3.14
Hy’s Law
Cases where a subject shows an AST or ALT ≥3×ULN with TBL ≥2×ULN may need to be 
reported as SAEs. Please refer to Appendix 12 for further instructions in cases of combined 
increase of aminotransferase and TBL.
7.3.15
Data Monitoring Committee
An independent, external Data Monitoring Committee (DMC) will be set up to review all 
SAEs (including deaths and all hospitalizations) and cardiovascular events. Members of the 
DMC will review summaries of these safety data generated externally and independently of 
the Sponsor in a semi-blinded or unblinded manner at predetermined intervals. If significant 
safety issues arise in between scheduled meetings, ad hoc meetings will be scheduled to 
review the data. Based on the safety implications of the data, the DMC may recommend 
modification or termination of the study.
7.4
Termination of Study
An Investigator may choose to discontinue study participation at any time, for any reason and 
should provide sufficient notice per the terms of the contract with the Sponsor.
The Sponsor reserves the right to terminate the study at any time for clinical or 
administrative reasons. Such a termination must be implemented by the Investigator, if 
instructed to do so by the Sponsor, in a timeframe that is compatible with the subjects’ 
welfare.

STUDY ACTIVITIES
Please refer to Section 7 for a complete and detailed description of all study procedures and 
their respective timing. The overall schedule of events is provided in Table 8-1. A detailed 
schedule is provided for the timing of assessments of all post-randomization visits in 
Table 8-2. A detailed schedule of events for 24-hour Holter monitoring sub-study at Visits 3 
and 7 is provided in Table 8-3.
8.1
General Study Considerations
•
In order to minimize diurnal variance, sites should make every effort to assess subjects in 
clinic at the same time throughout the study. The first dose of study drug administered in 
the clinic should be planned to occur at approximately the same time the subject will 
typically administer study drug in the morning at home. However, sites should also make 
every effort to ensure that the morning study drug dosing occurs before 10 am.
•
The subject should then be advised that subsequent morning study drug dosing should 
occur at approximately the same time every day and that evening study drug dosing 
should occur as close as possible to 12 hours from the time of morning study drug dosing.
•
Sites should discuss the importance of study drug dosing at a consistent time linked to the 
time of study drug dosing at randomization. For example, if the study drug dose at 
randomization is administered at 8 am, all subsequent doses should be administered as 
close as possible to 8 am and 8 pm. In this case, all visits should be scheduled to support 
in-clinic dosing as close to 8 am (the timing of the initial dose at Visit 4) as possible.
•
Subjects will be required to return to clinic at approximately the same time as Visit 1 for 
all treatment visits (±1 hour) and dosing time should not exceed 10 am. Subjects will be 
required to remain at the clinic until completion of all protocol-defined assessments.
•
The day before study visits, sites should contact subjects to confirm timing of the evening 
study drug dose and the expected timing of the in-clinic study drug dose. If the in-clinic 
dose will occur later than the subject typically takes their morning dose, the subject must 
be instructed to take their evening dose 12 hours prior to the expected in-clinic dosing 
time. Sites should instruct each subject as follows during this reminder phone call:
-
To take their last dose the evening before the scheduled visit
-
To bring their study medications and eDiary with them to the clinic
-
To withhold all inhaled medications (oral and intranasal) for at least 6 hours prior to 
PFTs
•
Subjects who inadvertently took asthma medication(s) within 6 hours of the start of study 
procedures must have their clinic visit delayed (but not to exceed study drug dosing by 
10 am) or rescheduled within the specified visit window.
•
Subjects must not ingest xanthine and/or xanthine analogue (caffeine)-containing foods 
or beverages or caffeine-containing medications for at least 6 hours prior to each study 
visit and for the duration of each study visit. Examples of such products include coffee, 
tea, chocolate, and cola. Decaffeinated beverages are acceptable.

•
Site personnel will instruct subjects not to take any asthma medications without site 
personnel permission during a clinic visit until all study procedures have been completed, 
and the subject is discharged. Site personnel should take every precaution to prevent 
subject use of asthma medications during the study visit. Subjects will be asked to abstain 
wherever possible from using rescue albuterol during study clinic visits. If a subject is 
experiencing severe symptoms and requires albuterol for relief of asthma symptoms at 
any time during a study visit, site personnel must note the time and justification of use in 
the subject’s chart and all subsequent spirometry assessments should be stopped. 
However, safety assessments should be continued at the discretion of the Investigator.

a
Screening Period of 11 to 28 days. Site should make every effort to maintain subjects within the scheduled visit windows. Subjects who fall outside the visit 
window will be placed in the appropriate window at the next scheduled visit.
b
Subjects will return for Visit 2 at least 7 days after Visit 1 to allow for eDiary compliance review and re-training as necessary.
c
Sites should call subjects 1 to 2 days before each scheduled visit to remind the subject of the visit and the required medication washouts and to bring all 
study-assigned medications and eDiary.
d
Collect medical history information at Visit 1 and update during the Screening Period if necessary.
e
Determine timing of last doses of short-acting bronchodilators, ICS/LABA, and study drug (Visits 5 through 10). Short-acting bronchodilators must be held 
for at least 6 hours prior to spirometry, and morning doses of ICS/LABA and study drug need to be withheld. With the exception of Visit 1, if these timelines 
have not been met, visits must be rescheduled and must occur within the specified windows. With the exception of reversibility testing, all other procedures 
at Visit 1 may take place if subjects did not withhold these medications.
f
Subjects taking tiotropium will discontinue this medication and be provided ipratropium to take 2 puffs QID until 6 hours prior to spirometry on the morning 
of Visit 4. All subjects will continue taking their regular ICS/LABA and will use Sponsor-provided albuterol as needed for rescue.
g
All pre-dose (trough) spirometry and all in-clinic dosing must occur between 7 am and 10 am and within ±1 hour of the Visit 1 time and approximately 
12 hours after the evening dose of BID study treatments (see Section 8.1). Subjects will be required to return to the clinic at approximately the same time as 
Visit 1 for all treatment visits (±1 hour).
h
Subjects will be tested for reversibility at 30 minutes following 4 puffs of albuterol (Visit 1 and, if needed, Visit 2) and ipratropium (Visit 3). If subjects are 
not reversible at 30 minutes, the post-dose PFT can be repeated at 60 minutes post-dose for qualification for albuterol (Section 7.1.1.3). Spirometry is not

required at Visit 2 unless the subject does not demonstrate reversibility to albuterol at Visit 1. If pre-dose spirometry is performed at Visit 2 due to the 
subject not demonstrating reversibility to albuterol at Visit 1, the pre-dose FEV1 should be >40% and <85 % of predicted normal for subjects 18 to 80 years 
of age or >40% and <90% for subjects 12 to <18 years of age. Repeat spirometry at 60 minutes post-dose is not necessary for reversibility testing to

Note: Time point for study drug and ICS/LABA dosing is regarded as “0 minutes” and pre- and post-dose are relative to study drug and ICS/LABA dosing. 
When data collection time points are concurrent, variables should be collected in the following order: ACQ, AQLQ +12, vital signs, ECG, clinical laboratory 
samples, FENO, eDiary review, and spirometry.
a
At the start of the Treatment Visit, subjects must have withheld morning doses of study drug and ICS/LABA (and ipratropium, as applicable, for Visit 4) and 
rescue albuterol for at least 6 hours prior to start of test day procedures.
b
This assessment should be performed pre-dose, at an appropriate time to allow for collection of timed pre-dose spirometry.
c
Vital signs (HR, DBP, and SBP only) should be started approximately 5 to 10 minutes ahead of the specified time point to ensure spirometry will be 
conducted as close as possible to the specified time points. 
d
Samples for clinical laboratory tests will be collected within 60 minutes prior to dosing. Pregnancy tests will be performed on urine (on site) before study 
drug and ICS/LABA dosing at Visits 4 through 9, and on serum at Visit 10/Final Visit. 
e
Pre-dose spirometry must be performed between 7 am and 10 am, within ±1 hour of the time of the Visit 1 spirometry, ±15 minutes of the specified time 
before study drug and ICS/LABA administration and, for subjects randomized to BID study drug treatment, approximately 12 hours after the evening study 
drug dose. 
f
Post-dose spirometry should be conducted ±5 minutes of the specified time for the first 60 minutes after study drug and ICS/LABA administration, and 
±15 minutes of the specified time point for assessments obtained thereafter.
g
Dispense study drug to subjects for at-home use. At Visit 10, study drug will be dispensed for the final in-clinic dose only.
h
Schedule next visit following completion of all post-dose assessments.

Procedures for Treatment Discontinuation and Study Withdrawal 
Visits
Subjects who discontinue study drug (treatment) before the end of the study will be 
encouraged to remain in the study to complete all remaining study visits and procedures 
during the randomized Treatment Period. Procedures for subjects who agree to be followed 
after treatment discontinuation are described in Section 8.9.1 and procedures for subjects 
who withdraw from study participation are described in Section 8.9.2.
8.9.1
Treatment Discontinuation 
Subjects who agree to continue to be followed beyond discontinuation of only study 
treatment will sign an ICF/assent addendum and complete a Treatment Discontinuation Visit 
(see Section 8.9.3) before transitioning back to regularly scheduled study visits. No 14-day 
follow-up phone call is needed if the subject completes a study visit ≥ 14 days after the 
Treatment discontinuation visit. After the Treatment Discontinuation Visit, subjects will 
return to appropriate maintenance asthma medications at the Investigator's discretion, and the 
prohibited medications in Section 5.7 will no longer apply. 
For subjects who discontinue randomized study drug (ie, Treatment Discontinuation) but are 
planning to continue study participation (ie, planning to complete all remaining study visits 
and procedures), all AEs/SAEs will be collected through the last study visit or early 
termination visit.
8.9.2
Study Withdrawal
If a subject discontinues study treatment and chooses not to continue with study assessments, 
the subject should complete at least the minimum procedures for Visit 10/Final Visit at the 
Study Withdrawal Visit (see Section 8.9.3). After that visit, subjects will return to 
appropriate maintenance asthma medications at the Investigator's discretion. 
All AEs/SAEs will be collected through 14 (+2) days after the last dose of study drug. This 
can occur via a follow-up telephone call (Section 8.11) or a study visit, whichever follow-up 
type provides 14 (+2) days of AE/SAE follow-up.
8.9.3
Study Visit Procedures
Unless otherwise indicated, the following minimum procedures will be completed for either a 
Treatment Discontinuation Visit or a Study Withdrawal Visit:
•
Complete ACQ and AQLQ +12
•
Record asthma exacerbations and AEs (if any)
•
Review/update concomitant medication history
•

Unscheduled Visits in the eCRF.
Procedures for the Treatment Discontinuation Visit and Study Withdrawal Visit are shown in 
Section 8.9.
8.11
Follow-Up Telephone Call
For subjects that complete 24 weeks of study drug, use of concomitant medications and 
AEs/SAEs (if any) will be collected through 14 (+2) days after the last dose of study drug. 
Previously ongoing asthma exacerbations will also be reviewed. This can occur via a follow-
up telephone call or a study visit, whichever follow-up type provides 14 (+2) days of 
concomitant medication and AE/SAE follow-up.
8.12
Completion of the Study
The Investigator will document study completion or the reason for early study drug 
discontinuation or study withdrawal by a subject in the eCRF.

Analysis Sets and Estimands
9.3.1
Analysis Sets
The following analysis sets are defined in this study: 
•
The Intent-to Treat (ITT) analysis set is defined as the data from all subjects who are 
randomized to treatment and use any amount of the study treatment. Subjects will be 
analyzed according to the treatment they were assigned at randomization. Data obtained 
after discontinuation of treatment, but prior to withdrawal from the study, will be 
included in the ITT analysis set.
•
The Modified Intent-to-Treat (mITT) analysis set is a subset of the ITT analysis set and is 
defined as the data from all subjects with post-randomization data obtained prior to 
discontinuation from treatment. Any data collected after completion of or discontinuation 
from randomized study medication will be excluded from the mITT analysis set but will 
still be included in the ITT analysis set. Subjects will be analyzed according to 
randomized treatment group. It is noted that a subject who used a study treatment, but 
took less than 1 full dose of treatment, will qualify for this analysis set. The mITT

analysis set will be the primary analysis set for all efficacy analyses. Note: The 
knowledge that a subject did not have an exacerbation constitutes an efficacy assessment.
•
The Safety analysis set is defined as data from all subjects who are randomized to 
treatment and receive any amount of the study treatment. However, subjects will be 
analyzed according to treatment received rather than randomized. If a subject receives 
more than 1 randomized treatment, they will be analyzed and included in summaries 
according to the treatment they received the most. Subjects receiving no study treatment 
will be excluded, as will subjects who have no post-dose safety assessments. Note: The 
statement that a subject has no AEs also constitutes a safety assessment.
•
The Holter Monitoring analysis set is defined as all subjects in the Safety analysis set 
who had at least 18 hours of acceptable quality Holter monitoring data at both Visit 3 
(Holter Baseline) and Visit 7 (Week 12). Data judged to be impacted by major protocol 
deviations will be determined prior to database lock and excluded per the statistical 
protocol deviation plan.
9.3.2
Estimands
Three estimands are of interest in this trial:
•
The primary estimand of interest is the Efficacy Estimand, defined as the effect of the 
randomized treatments in all subjects assuming continuation of randomized treatments 
for the duration of the study, regardless of actual compliance. 
•
The second estimand of interest is the Attributable Estimand, defined as the effect of 
treatment in subjects attributable to the randomized treatment. For this estimand, 
discontinuation of randomized treatment for reasons such as tolerability or lack of 
efficacy is considered a bad outcome. 
•
The third estimand of interest is the Treatment Policy Estimand, defined as the effect of 
randomized treatment over the study period regardless of whether randomized treatment 
is continued. 
Analysis of the Efficacy Estimand will be conducted using the mITT analysis set where only 
data obtained prior to subjects discontinuing from randomized treatment will be utilized. This 
assumes that efficacy observed on treatment is reflective of what would have occurred after 
discontinuation of randomized treatment had they remained on treatment. 
Analysis of the Attributable Estimand will be conducted in the mITT analysis set, but data 
that are missing due to treatment discontinuation will be imputed based on the 95th or the 5th
percentile of the reference arm’s distribution if the reason is reasonably attributable to 
tolerability or lack of efficacy. The 95th percentile would apply to an endpoint for which a 
higher value is a worse outcome, while the 5th percentile would apply to an endpoint for 
which a higher value is a better outcome. More detail about the computation of the 
Attributable Estimand will be provided in the SAP.

Analysis of the Treatment Policy Estimand will be conducted in the ITT analysis set, in 
which all observed data will be utilized regardless of whether subjects remain on randomized 
treatment.
9.4
Demographic and Baseline Characteristics
Demographic and baseline characteristics data will be summarized by treatment for the mITT 
and Safety analysis sets.
9.5
Efficacy Analysis
All efficacy assessments are relative to baseline. Baseline for spirometry endpoints will be 
defined as the mean of the 60- and 30-minute pre-dose values at the randomization visit. 
Though all possible comparisons will be performed, the key comparisons will be those 
between each dose of GP MDI with Placebo MDI and, for benchmarking purposes, Spiriva 
Respimat.
9.5.1
Primary Efficacy Analysis
The primary analysis will be conducted for the Efficacy Estimand where only data obtained 
prior to subjects discontinuing from study drug will be utilized. Analyses will also be 
conducted for the Attributable and Treatment Policy Estimands. 
For the primary comparisons, the null hypothesis for each pair-wise comparison will be that 
the mean treatment difference is zero (mean treatment effects are equal). The alternative 
hypothesis is that the mean treatment difference is not zero (mean treatment effects are not 
equal). All p-values will be reported as 2-sided. 
9.5.1.1
Change From Baseline in FEV1 AUC0-4
Change from baseline in FEV1 AUC0-4 will be analyzed using a linear repeated measures 
analysis of covariance (ANCOVA) model. The model will include treatment, visit, 
background fixed-dose ICS/LABA combination product, and treatment-by-visit interaction 
as categorical covariates and baseline FEV1, percentage reversibility to ipratropium, and 
blood eosinophil count at screening as continuous covariates. An unstructured matrix will be 
used to model the variance-covariance structure. If this model fails to converge, an 
alternative structure will be employed as pre-specified in the SAP. Contrasts will be used to 
obtain estimates of the treatment differences at Week 24. Two-sided p-values and point 
estimates with 2-sided 95% confidence intervals will be produced for each treatment 
difference.
The FEV1 AUC0-4 will be calculated for the changes from baseline using the trapezoidal rule 
and will be normalized by dividing by the time (in hours) from dosing to the last 
measurement included (ie, 4 hours). For the Efficacy Estimand analysis, only 1 non-missing, 
post-dose value is required for the calculation of FEV1 AUC0-4. Actual time from dosing will 
be used in the calculation if available; otherwise, scheduled time will be used.

9.5.2
Secondary Efficacy Analysis
Similar to the primary efficacy analysis, the secondary efficacy analyses will be conducted 
for the Efficacy Estimand. Analyses will also be conducted for the Attributable and 
Treatment Policy Estimands.
9.5.2.1
Change From Baseline in Morning Pre-Dose Trough FEV1
Change from baseline in morning pre-dose trough FEV1 will be analyzed using a linear 
repeated measures ANCOVA model. The model will be similar to the one used for FEV1
AUC0-4. Contrasts will be used to obtain estimates of the treatment differences at Week 24. 
Two-sided p-values and point estimates with 2-sided 95% confidence intervals will be 
produced for each treatment difference
9.5.2.2
Rate of Moderate/Severe Asthma Exacerbations
The ratio of the rates of moderate/severe asthma exacerbations will be analyzed with 
negative binomial regression. Asthma exacerbations will be considered separate events if 
more than 7 days are between the recorded stop date of the earlier event and start date of the 
later event. Time at risk of experiencing an exacerbation will be used as an offset variable in 
the model. Time during an exacerbation or in the 7 days following an exacerbation will not 
be included in the calculation of exposure. Treatments will be compared adjusting for 
baseline post-bronchodilator percent predicted FEV1, baseline asthma exacerbation history, 
blood eosinophil count at screening, background ICS/LABA, and reversibility to 
ipratropium.
The number and percentage of subjects with exacerbations in each treatment group will be 
tabulated.
9.5.2.3
Change From Baseline in ACQ-7, ACQ-5, and AQLQ +12
Change from baseline in ACQ-7, ACQ-5, and AQLQ +12 will be analyzed using a linear 
repeated measures ANCOVA model. The model will include treatment, visit, background 
fixed-dose ICS/LABA combination product, and treatment-by-visit interaction as categorical 
covariates and baseline post-bronchodilator FEV1 percent predicted, baseline score for the 
patient-reported outcome instrument, percentage reversibility to ipratropium, and blood 
eosinophil count at screening as continuous covariates. Contrasts will be used to obtain 
estimates of the treatment differences at Week 24. Two-sided p-values and point estimates 
with 2-sided 95% confidence intervals will be produced for each treatment difference.
9.5.3
Other Efficacy Analyses 
Other efficacy analyses will be conducted for the Efficacy Estimand only.
9.5.3.1
Percentage of Responders in ACQ-5, ACQ-6, ACQ-7, and AQLQ +12
Responder analyses will be performed for ACQ-5, ACQ-6, ACQ-7, and AQLQ +12 at 
Week 24 and over the Treatment Period. Responders are defined as subjects with an

improvement of ≥0.5 points over baseline. Subjects who discontinue treatment for any reason 
will be classified as non-responders.
Logistic regression will be used to compare the treatment groups with background 
ICS/LABA as categorical covariates and baseline instrument score, blood eosinophil count at 
screening, percentage reversibility to ipratropium, and baseline post-bronchodilator percent 
predicted FEV1 as continuous covariates. P-values and odds ratios with 95% confidence 
intervals will be produced for each treatment comparison.
9.5.3.2
Change from Baseline in ACQ-6
Change from baseline in ACQ-6 will be analyzed using a linear repeated measures 
ANCOVA model. The model will include treatment, visit, background fixed-dose 
ICS/LABA combination product, and treatment-by-visit interaction as categorical covariates 
and baseline post-bronchodilator FEV1 percent predicted, baseline score for the patient-
reported outcome instrument, percentage reversibility to ipratropium, and blood eosinophil 
count at screening as continuous covariates. Contrasts will be used to obtain estimates of the 
treatment differences at Week 24. Two-sided p-values and point estimates with 2-sided 95% 
confidence intervals will be produced for each treatment difference.
9.5.3.3
Time to First Asthma Exacerbation 
Time to first moderate or severe asthma exacerbation will be analyzed with a Cox regression 
model to compare the treatment groups, adjusted for asthma exacerbation history, 
background ICS/LABA, reversibility to ipratropium, blood eosinophil count at screening, 
and baseline post-bronchodilator FEV1 percent predicted.
Time to first severe asthma exacerbation and time to first exacerbation of any severity will 
each be analyzed in a manner similar to the analysis of time to first moderate or severe 
asthma exacerbation.
9.5.3.4
Rate of Severe Asthma Exacerbations or Exacerbations of Any Severity
Severe asthma exacerbations and asthma exacerbations of any severity will each be analyzed 
in a manner similar to the analysis of the rate of moderate/severe asthma exacerbations.
9.5.3.5
Peak FEV1
Change from baseline in peak FEV1 will be analyzed at each clinic visit using a linear 
repeated measures ANCOVA model. The model will be similar to the one used for the 
primary analyses.
9.5.3.6
Percentage of Symptom-Free Days, Rescue-Free Days, and Asthma Control 
Days
The percentages of symptom-free days, rescue-free days, and asthma control days will each 
be analyzed over the entire Treatment Period. Additionally, analyses will be conducted over 
each 4-week interval in the study. An ANCOVA model will be used with treatment, the

number of the relevant 4-week interval (interval 1 to 6), asthma exacerbation history, 
background ICS/LABA, and the treatment-by-4-week interval interaction as categorical 
covariates. Baseline percentage of endpoint days (where endpoint is symptom free, rescue 
free, or asthma control per model), baseline post-bronchodilator FEV1 percent predicted, 
percentage reversibility to ipratropium, and blood eosinophil count at screening will be 
continuous covariates.
9.5.3.7
Rescue Medication Usage
The mean daily number of puffs of rescue medication use will be calculated overall and for 
each of the 4-week intervals during the Treatment Period. For every period of time for which 
the mean number of puffs of rescue medication will be calculated, missing values will be 
ignored in both the numerator and denominator. As such, the denominator will be adjusted 
based on the number of days (including half days) with non-missing values.
A linear repeated measures ANCOVA model will be used to analyze change from baseline in 
average daily rescue albuterol use. The model will include treatment, the number of the 
relevant 4-week interval (interval 1 to 6), asthma exacerbation history, background 
ICS/LABA, and the treatment-by-4-week interval interaction as categorical covariates and 
blood eosinophil count at screening, baseline daily rescue albuterol use, percentage 
reversibility to ipratropium, and baseline post-bronchodilator FEV1 percent predicted as 
continuous covariates. 
An unstructured variance-covariance matrix will be fit. If this model fails to converge, an 
alternative structure will be employed as pre-specified in the SAP. Contrasts will be used to 
obtain estimates of the treatment differences over 24 weeks. Two-sided p-values and point 
estimates with 2-sided 95% confidence intervals will be produced for each treatment 
difference.
9.5.3.8
Change From Baseline in Morning PEFR and Evening PEFR
Change from baseline in morning PEFR and evening PEFR will be analyzed over 4-week 
intervals using a linear repeated measures ANCOVA model.
9.5.3.9
FENO
Change from baseline in FENO will be analyzed using a linear repeated measures ANCOVA 
model. The model will be similar to the one used for the primary analyses.
Clinically meaningful increases and decreases from baseline in FENO will be summarized 
descriptively by visit. The clinically meaningful changes are defined below:
•
A clinically meaningful increase in FENO is defined as an increase of 20% or more from 
baseline if the baseline is 50 parts per billion (ppb) or more or an increase of more than 
10 ppb from baseline if the baseline is less than 50 ppb.

•
A clinically meaningful decrease in FENO is defined as a decrease of 20% or more from 
baseline if the baseline value is 50 ppb or more or a decrease of more than 10 ppb from 
baseline if the baseline value is less than 50 ppb.
At each visit, the percentage of subjects with FENO less than 25 ppb, between 25 and less than 
50 ppb, and at least 50 ppb will be summarized descriptively by treatment.
9.5.3.10
CompEx
Time to first CompEx event will be analyzed with a Cox regression model to compare the 
treatment groups adjusted for asthma exacerbation history, background ICS/LABA, 
reversibility to ipratropium, blood eosinophil count at screening, and baseline post-
bronchodilator FEV1 percent predicted. Subjects who do not experience a CompEx event will 
be censored at their Week 24 Visit. 
9.5.4
Subgroup Analyses
Analyses of the primary, secondary, and other endpoints may be performed by various 
subgroups. In addition to baseline and demographic subgroups, other factors (T-helper cell 
type 2 high or low, GINA classification, etc) will be used to create subgroups of interest. All 
subgroup analyses will be described fully in the SAP.
9.5.5
Type I Error Control
The Type I error rate will be controlled within the primary and secondary efficacy analyses. 
As a general strategy, the Type I error rate will be strongly controlled within the primary 
analysis. The Type I error rate will also be controlled within the family of secondary analyses 
within a GP MDI treatment group.
Primary analysis testing will be conducted in descending dose order, with the highest dose of 
GP MDI tested against placebo at the nominal alpha. Testing will continue through the 
GP MDI doses as long as the results are successful. Testing will stop if any comparison of 
GP MDI versus placebo fails to meet statistical significance. Through this strategy, the 
Type I error rate of the primary analyses of all 3 GP MDI doses versus placebo will be 
strictly controlled to the nominal alpha.
The secondary analyses for each dose of GP MDI versus placebo will proceed only if the 
primary analysis for that GP MDI dose is successful. The Type I error rate within the 
secondary analyses of each GP MDI dose versus placebo will be controlled with a multiple 
comparison procedure as specified in the SAP.

Safety Analysis
9.6.1
AEs
Adverse events during the Treatment Period will be summarized by the number of subjects 
experiencing an event. Adverse events will be tabulated at the level of the Medical 
Dictionary for Regulatory Activities (MedDRA) system organ class and preferred term. The 
version of MedDRA current at the time of database lock will be used in the tabulations and 
listings. Tabulations will be broken down by severity, seriousness, AEs leading to 
discontinuation, and by relationship to study drug. No hypothesis tests will be performed.
9.6.2
AESIs
The AESIs will be tabulated by treatment group. Additional analyses may be performed and 
will be detailed in the SAP.
9.6.3
Clinical Laboratory Measurements
Summary statistics (mean, median, standard deviation [SD], and range) of change from 
baseline values will be tabulated for each treatment and each assessment time. For clinical 
laboratory measurements, baseline will be defined as the last available value prior to 
randomization. Potentially clinically significant values will be identified and summarized.
9.6.4
Vital Signs
Summary statistics (mean, median, SD, and range) of change from baseline will be tabulated 
by vital sign parameter and treatment for each scheduled assessment time. For vital signs, 
baseline will be defined as the average of the values prior to dosing on the day of 
randomization. In addition, potentially clinically significant values will be identified and 
summarized.
9.6.5
ECGs
Summary statistics (mean, median, SD, and range) for absolute values and change from 
baseline will be tabulated by ECG parameter and treatment for each scheduled assessment 
time. For ECG parameters, baseline values will be defined as the last value obtained prior to 
randomization. In addition, potentially clinically significant values will be identified and 
summarized.
9.6.6
24-Hour Holter Monitoring
Holter monitoring endpoints are listed in Section 3.5.
Change from baseline in the ventricular and supraventricular variables will be analyzed with 
nonparametric methods. The Wilcoxon Rank Sum Test will be used to produce p-values for 
the pairwise comparison of treatments. The median treatment differences will be presented 
with 95% confidence intervals based on the Hodges-Lehmann approach. The number of

subjects experiencing a ventricular couplet, ventricular run, supraventricular couplet, and 
supraventricular run at Week 12 will be analyzed with a logistic regression model. 
Alternative analysis methods may be employed if found to be appropriate and will be pre-
specified in the SAP.
Additionally, for the endpoints that involve incidences and proportions of events, those 
values will be summarized by treatment.
9.7
Sample Size Consideration
A sample size of 1125 subjects (250 subjects per double-blind treatment group, 125 subjects 
in the open-label Spiriva Respimat treatment group) will provide approximately 93% power 
to detect a 120 mL difference between the GP MDI treatment groups and Placebo MDI in the 
analysis of change from baseline in FEV1 AUC0-4 at Week 24. The assumed SD is 348 mL at 
each visit. The 2-sided alpha for each pairwise comparison is 0.05. 
Comparisons of GP MDI to Spiriva Respimat will be focused on estimation as the study is 
not formally powered to demonstrate non-inferiority or superiority.
For the secondary endpoint of change from baseline in morning pre-dose trough FEV1 at 
Week 24, it is assumed that the difference between GP MDI and Placebo MDI is 90 mL, with 
each treatment group having an SD of 317 mL at each visit. Under these assumptions, the 
study will have 80% power to declare GP MDI superior to Placebo MDI in the analysis of 
change from baseline in morning pre-dose trough FEV1 at Week 24. 
The Type I error rate will be strongly controlled for the primary analyses. The Type I error 
control strategy for the primary and secondary analyses are described in Section 9.5.5. This 
sample size assumes that approximately 20% of randomized subjects will have discontinued 
study drug prior to Week 24.
9.8
Data Validation and Transformation
In general, the distribution of spirometry measures is well approximated by a normal 
distribution. Under some circumstances, however, extreme and atypical values can arise. 
Such values have high influence on estimation of variance parameters and on standard errors 
of fixed effect estimates. The distribution of residuals and influence statistics will be 
examined to identify such cases prior to unblinding. In the event that a single or small 
number of such outlying values are found to exist and found to be highly influential, the 
effects may be ameliorated either by transformation or by removal of the outlier. 
Transformations to be considered may include the logarithmic transformation, or normal rank 
transformations. Any changes will be documented prior to unblinding and, where outliers are 
removed, sensitivity analyses including those values will be reported. Changes in spirometry 
measures from baseline, and from time point to time point will be examined graphically 
before data base lock, and before unblinding, as part of data quality management.

and the quality of the data produced must be maintained for review by the Sponsor 's Quality 
Assurance auditors and by all applicable regulatory authorities. The period of time these 
documents must be maintained is governed by county-specific regulations. The Sponsor or 
its designee will inform the Investigator when these documents may be destroyed. The 
Sponsor or its designee must be notified in writing at least 6 months prior to the intended 
date of disposal of any study-related documents to allow the Sponsor to make alternate 
storage arrangements.
10.10 Financial Disclosure
The Principal Investigator or sub-Investigators named on FDA Form 1572 will need to 
complete a financial disclosure form prior to study initiation, at any time during the study if 
new information needs to be disclosed, and for 1 year after study completion. Investigators 
should make the IRB/IEC aware of any financial interests that the Investigator has in the 
investigational product.
10.11 Investigator’s Final Report
Following completion of the study, the Investigator will submit a final written report to the 
Sponsor.
10.12 Publication and Disclosure Policy
The Sponsor intends to publish the results of all the clinical studies that it sponsors in 
compliance with the Declaration of Helsinki. 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 sponsored studies should fairly 
recognize the activities of those that have made a significant contribution to the study. In 
addition, the Sponsor recognizes and adheres to the precepts of the International Society for 
Medical Publications Professionals (ISMPP), which provides guidance to the preparation of 
publications, disclosure of conflicts of interest, and the protection of intellectual property. 
Thus, it is anticipated that authorship will reflect the contribution made by the Sponsor’s 
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, the Sponsor 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. The Sponsor (or its representatives) is 

Glycopyrronium Inhalation Aerosol

Clinical Study Protocol: PT001102-04
Version 5.0
Confidential and Proprietary
Page 104 of 163
responsible for the accuracy of the data entered into the study databases and for the 
accuracy of the analyses conducted.
2. Authorship and Publication Committee: The Sponsor, in collaboration with the 
Investigators, will establish the appropriate authorship and responsibility for drafting 
study documents in accordance with the principles of the ICMJE and ISMPP. 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 first 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 the 
Sponsor for review, approval, and to ensure consistency with the policy in this protocol. 
The Sponsor 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 the Sponsor 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 the Sponsor to publish the 
study in a fair and accurate manner, the Sponsor 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 the Sponsor 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, the Sponsor reports clinical findings based on the 
guidance of The CONsolidated Standards of Reporting Trials Statement (Moher 2012) 
and a 25-item checklist that is intended to improve the reporting of a randomized 
controlled trial, 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, the Sponsor 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.

Spirometry Assessment Criteria 
Acceptable Versus Usable Tests
Acceptable Tests must meet the following 7 Criteria:
1. Acceptable start of exhalation with brisk upstroke, no hesitation or false start, and back 
extrapolation volume (EV) <5% of forced vital capacity (FVC) or 0.150 L, whichever is 
the greater. (Refer to example in Figure A1-1)
2. No cough during the first second.
3. No valsalva maneuver.
4. No leak.
5. No obstruction of mouthpiece.
6. No extra breaths.
7. Plateau achieved, ie, the volume-time curve shows no change in volume (<0.025 L) for 
≥1 second, and the patient has tried to exhale for at least 6 seconds.
An acceptable test meets all 7 criteria listed. This is to be considered the “gold standard”.
Usable spirometry tracings are those that only meet criteria 1 and 2 (Figure A1-1). When this 
occurs, repeat testing up to 8 attempts in an effort to obtain 3 acceptable spirograms. If only 
usable tests are obtained, report results based on the 3 best usable results with observed 
limitations.

through the steepest part of the curve, where flow is peak expiratory flow (PEF), to determine the new “time 
zero”. Forced vital capacity (FVC) -4.291 L; back-extrapolated volume (EV) – 0.123 L (2.9% FVC): back-
extrapolation line through PEF.

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

Appendix 3
Spirometry Performance Recommendations
Spirometry data of the highest quality must be obtained for proper interpretation of the 
results of this protocol. To these ends, a standard spirometer will be used (provided by Pearl), 
central training provided, qualification will be required, and specific operating instruction 
will also be provided. 
The following instructions are supported by ATS/ERS defined criteria (Miller 2005).
FEV1 AND FVC MANEUVERS
Equipment Requirements
The spirometer must be capable of accumulating volume for ≥15 s (longer times are 
recommended) and measuring volumes of ≥8 L (body temperature (ie, 37°C), ambient 
pressure, saturated with water vapor, body temperature and pressure saturated [BTPS]) with 
an accuracy of at least ±3% of reading or ±0.050 L, whichever is greater, with flows between 
0 and 14 L-s -1. The total resistance to airflow at 14.0 L-s -1 must be <1.5 cmH2O L-1 1s -1
(0.15 kPa L-1 1s -1). The total resistance must be measured with any tubing, valves, pre filter, 
etc. included that may be inserted between the subject and the spirometer. Some devices may 
exhibit changes in resistance due to water vapor condensation, and accuracy requirements 
must be met under BTPS conditions for up to 8 successive forced vital capacity (FVC) 
maneuvers performed in a 10-minute period without inspiration from the instrument.
Display
For optimal quality control, both flow volume and volume time displays are useful, and test 
operators should visually inspect the performance of each maneuver for quality assurance 
before proceeding with another maneuver. This inspection requires tracings to meet the 
minimum size and resolution requirements set forth in this standard. Displays of flow vs. 
volume provide more detail for the initial portion (first 1 s) of the FVC maneuver. Since this 
portion of the maneuver, particularly the peak expiratory flow rate, is correlated with the 
pleural pressure during the maneuver, the flow–volume display is useful to assess the 
magnitude of effort during the initial portions of the maneuver. The ability to overlay a series 
of flow–volume curves registered at the point of maximal inhalation may be helpful in 
evaluating repeatability and detecting sub maximal efforts. However, if the point of maximal 
inhalation varies between blows, then the interpretation of these results is difficult because 
the flows at identical measured volumes are being achieved at different absolute lung 
volumes. In contrast, display of the FVC maneuver as a volume–time graph provides more 
detail for the latter part of the maneuver. A volume–time tracing of sufficient size also allows 
independent measurement and calculation of parameters from the FVC maneuvers. In a 
display of multiple trials, the sequencing of the blows should be apparent to the user. For the 
start of test display, the volume–time display should include >0.25 s, and preferably 1 s, 
before exhalation starts (zero volume). This time period before there is any change in volume 
is needed to calculate the back extrapolated volume (EV) and to evaluate effort during the 
initial portion of the maneuver. Time zero, as defined by EV, must be presented as the zero

point on the graphical output. The last 2 s of the maneuver should be displayed to indicate a 
satisfactory end of test.
When a volume–time curve is plotted as hardcopy, the volume scale must be ≥10 mm L-1
(BTPS). For a screen display, 5 mm L-1 is satisfactory (Table A2-1).

*The correct aspect ratio for flow versus volume display is two units of flow per one unit of volume
The time scale should be ≥20 mm-s -1, and larger time scales are preferred (≥30 mm-s -1) 
when manual measurements are made. When the volume–time plot is used in conjunction 
with a flow–volume curve (ie, both display methods are provided for interpretations and no 
hand measurements are performed), the time scale requirement is reduced to 10 mm-s -1 from 
the usually required minimum of 20 mm-s -1 (Table A2-1). The rationale for this exception is 
that the flow–volume curve can provide the means for quality assessment during the initial 
portion of the FVC maneuver. The volume–time curve can be used to evaluate the latter part 
of the FVC maneuver, making the time scale less critical.
Validation
It is strongly recommended that spirometry systems should be evaluated using a computer 
driven mechanical syringe or its equivalent, in order to test the range of exhalations that are 
likely to be encountered in the test population. Testing the performance of equipment is not 
part of the usual laboratory procedures.
Quality Control
Attention to equipment quality control and calibration is an important part of Good 
Laboratory Practice. At a minimum, the requirements are as follows: 1) a log of calibration 
results is maintained; 2) the documentation of repairs or other alterations which return the 
equipment to acceptable operation; 3) the dates of computer software and hardware updates 
or changes; and 4) if equipment is changed or relocated (eg, industrial surveys), calibration 
checks and quality control procedures must be repeated before further testing begins.
Key aspects of equipment quality control are summarized in Table A2-2.

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

Page 114 of 163
The accuracy of the syringe volume must be considered in determining whether the measured 
volume is within acceptable limits. For example, if the syringe has an accuracy of 0.5%, a 
reading of ±3.5% is appropriate.
The calibration syringe should be stored and used in such a way as to maintain the same 
temperature and humidity of the testing site. This is best accomplished by keeping the 
syringe in close proximity to the spirometer, but out of direct sunlight and away from heat 
sources.
Volume type spirometer systems must be evaluated for leaks every day. The importance of 
undertaking this daily test cannot be overstressed. Leaks can be detected by applying a 
constant positive pressure of ≥3.0 cmH2O (0.3 kPa) with the spirometer outlet occluded 
(preferably at or including the mouthpiece). Any observed volume loss of 0.30 mL after 
1 minute indicates a leak and needs to be corrected.
At least quarterly, volume spirometers must have their calibration checked over their entire 
volume range using a calibrated syringe or an equivalent volume standard. The measured 
volume should be within ±3.5% of the reading or 65 mL, whichever is greater. This limit 
includes the 0.5% accuracy limit for a 3-L syringe. The linearity check procedure provided 
by the manufacturer can be used if it is equivalent to one of the following procedures: 
1) consecutive injections of 1-L volume increments while comparing observed volume with 
the corresponding cumulative measured volume (eg, 0–1,1–2, 2–3,…6–7 and 7–8 L, for an 
8-L spirometer); and 2) injection of a 3-L volume starting at a minimal spirometer volume, 
then repeating this with a 1-L increment in the start position (eg, 0–3, 1–4, 2–5, 3–6, 4–7, and 
5-8 L, for an 8-L spirometer). The linearity check is considered acceptable if the spirometer 
meets the volume accuracy requirements for all volumes tested.
Quality Control for Flow Measuring Devices
With regards to volume accuracy, calibration checks must be undertaken at least daily, using 
a 3-L syringe discharged at least three times to give a range of flows varying between 0.5 and 
12 L-s -1 (with 3-L injection times of 6 s and 0.5 s). The volume at each flow should meet the 
accuracy requirement of ±3.5%. For devices using disposable flow sensors, a new sensor 
from the supply used for subject tests should be tested each day.
For linearity, a volume calibration check should be performed weekly with a 3-L syringe to 
deliver three relatively constant flows at a low flow, then three at a mid-range flow and 
finally three at a high flow. The volumes achieved at each of these flows should each meet 
the accuracy requirement of ±3.5%.
VITAL CAPACITY AND INSPIRATORY CAPACITY MANEUVERS
Equipment
For measurements of vital capacity (VC) and inspiratory capacity, the spirometer or flow 
meter must comply with the requirements for FVC (as described previously) and be capable 
of accumulating volume for >30 s. Expiratory maneuvers or, ideally, both inspiratory and 

Glycopyrronium Inhalation Aerosol

Page 115 of 163
expiratory maneuvers should be included in the display of VC maneuver. Regardless of 
whether the inspiratory or expiratory maneuver is used for deriving measurements, a display 
of the entire recorded VC maneuver must be provided. The maximal expiratory volume must 
be assessed to determine whether the subject has obtained a plateau in the expiratory effort. 
For display of the slow VC, the time scale may be reduced to 5 mm-s -1.
TECHNICAL CONSIDERATIONS
Minimal Recommendations for Spirometry Systems
Accurate results require accurate equipment. Spirometer equipment recommendations apply 
to all spirometers and are minimal requirements. In some circumstances, it may be 
appropriate to exceed these requirements (ie, in some research/surveillance applications). 
Instrumentation recommendations should be followed to provide accurate spirometric data 
and information that is comparable from laboratory to laboratory and from one time period to 
another. The accuracy of a spirometry system depends on characteristics of the entire system, 
from the volume or flow transducer and the use of an in line filter, to the recorder, display or 
processor. Changes in any aspect of the equipment or errors at any step in the process can 
affect the accuracy of the results. For example, if the BTPS correction factor is wrong, an 
accurately measured FVC will be incorrectly reported. Spirometers are not required to 
measure all of the indices in Table A2-3, but must meet the recommendations for those that 
are measured. Accuracy and repeatability recommendations apply over the entire volume 
range of the instrument.

BTPS Correction
All spirometry values should be reported at BTPS by any method (measuring temperature 
and barometric pressure) proven effective by the manufacturer. For volume-type spirometers, 
the temperature inside the spirometer should be measured for each breathing maneuver.

Regardless of the BTPS correction technique used, the ambient temperature must always be 
recorded with an accuracy of ±1°C. In situations where the ambient air temperature is 
changing rapidly (>3°C in <30 min), continuous temperature corrections may be necessary. 
Spirometer users should be aware of potential problems with testing performed at lower 
ambient temperatures: 17°C is the lower limit for ambient temperature, unless a manufacturer 
states that their spirometer will operate accurately at lower ambient temperatures. If 
barometric pressure is not used in calculating the BTPS correction factor, the range of 
barometric pressures over which the BTPS correction factor is valid must be published.

•
The parts of your inhaler are seen in Figure A4-1.
Figure A4-1
•
The Dose indicator lets you know about how many puffs are left in your inhaler and is 
the part of the inhaler that is pressed to dispense a puff of medication. See Figure A4-1.
•
The Dose indicator should be pointing just to the right of 120 when your inhaler is new. 
See Figure A4-1.
•
The Dose indicator has numbers for every 20 puffs. The Dose indicator display will 
move after every tenth puff.

•
For example, if the Dose indicator is pointing to 120 (see Figure A4-2a) and you take 
10 puffs it will move between 120 and 100. This means that there are 110 puffs of 
medicine left (see Figure A4-2b). After 10 more puffs are used, the Dose indicator
pointer will move to the number 100. This means that there are 100 puffs of medicine left 
(see Figure A4-2c).
•
The Dose indicator number will continue to change after every 20 puffs.
•
When the number in the Dose indicator window changes to 20 and the color behind the 
number changes to red, this means that there are only 20 puffs left in your inhaler. See 
Figure A4-2d.

Preparing the Inhaler for Use:
The inhaler comes in a foil pouch that contains a drying packet (desiccant).
•
Take the inhaler out of the foil pouch.
•
Throw away the pouch and the drying packet. Do not eat or inhale the contents of the 
drying packet. 
•
Remove the Cap from the Mouthpiece as shown in Figure A4-3.

Prime the inhaler before you use it for the first time.
Priming the Inhaler:
•
Check inside the Mouthpiece for objects before use.
•
Hold the Actuator with the Mouthpiece pointing away from you and others as shown in 
Figure A4-4a.
•
Shake the inhaler well before each puff.
•
Push down fully on the center (not ‘off center’) of the Dose indicator on top of the 
Canister (see Figure 1) until the Canister stops moving in the Actuator to release a 
puff from the Mouthpiece as shown in Figure A4-4b. Note: It is normal to hear a soft 
click from the dose indicator as it counts down during use.
•
Repeat this priming step 3 more times for a total of 4 times, shaking the inhaler each time 
before you press it.
•
After completing the 4 priming puffs, your inhaler is now primed ready to use for the first 
time.
You must re-prime your inhaler again if you have not used it in more than 7 days. Take the 
cap off the mouthpiece and shake and spray the inhaler 2 times into the air away from your 
face.

sure your tongue is away from the Mouthpiece.
•
Step 5: Take a deep breath in (inhale) slowly through your mouth while pressing down 
firmly on the center (not ‘off center’) of the Dose indicator until the Canister stops 
moving in the Actuator and a puff has been released. Then, stop pressing the Dose 
indicator. 
•
Step 6: When you have finished breathing in, remove the Mouthpiece from your mouth 
and hold your breath for 10 seconds or as long as comfortable. 
•
Step 7: Then, breathe out normally. 
Take your second puff of medicine by repeating Step 2 through Step 7. 
•
Step 8: Replace the Cap back on the Mouthpiece.

Fractional Nitric Oxide in Inhaled Breath
Fractional nitric oxide in inhaled breath (FENO) data of high and consistent quality must be 
obtained for proper interpretation of the results of this protocol. To these ends, a standard 
measurement device will be used, and training provided on its use and care; specific 
operating instruction will also be provided. 
Equipment 
The 
device 
 and all 
required accessories (eg, test kits) will be provided by Pearl and used by all sites. The 
 
 device is suitable for children, approximately 7 to 17 years of age, and adults 18 years 
and older.
A User Manual will also be provided (electronically, printed, or both) which includes 
detailed information for installation, use, troubleshooting, and preventive care for the Niox 
Vero device.
Procedures
Two valid, reproducible FENO measurements are required, in accordance with testing 
procedures recommended by the manufacturer and similar to those published by the 
American Thoracic Society and European Respiratory Society (ATS/ERS 2005). If either or 
both of the first 2 valid FENO measurements is < 30 ppb and the measurements are within 
2 ppb of each other, or if both measurements are > 30 ppb and within 10% of each other, then 
the test is considered reproducible and complete. 
Two values below or above the measurement range (5-300 ppb) are also considered 
reproducible. If the reproducibility criteria are not met within the first 2 exhalations, a 
participant has 2 additional exhalations to satisfy the criteria (up to a total of 4 trials). The 
examinee's exhalations for which the device does not display a valid reading, ie, exhalations 
that are either too strong or too weak, or any other reasons for failing to achieve a successful 
exhalation, will be recorded as attempts. Examinees may not always able to meet the criteria 
for a reproducible measurement. 
The results of each attempt will be recorded in the appropriate eCRF.

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

Glycopyrronium Inhalation Aerosol

Clinical Study Protocol: PT001102-04
Version 5.0
Confidential and Proprietary
Page 160 of 163
The Investigator will also remain vigilant for any laboratory reports where the identification 
criteria are met, the Investigator will:
•
Request a repeat of the test (new blood draw) by the central laboratory
When the identification criteria are met from central laboratory results the Investigator will 
without delay:
•
Determine whether the subject meets PHL criteria by reviewing all laboratory reports 
including previous visits
•
Notify the Sponsor representative
FOLLOW-UP
Potential Hy’s Law Criteria not met
If the subject does not meet PHL criteria the Investigator will:
•
Inform the Sponsor representative that the subject has not met PHL criteria
•
Perform follow up on subsequent laboratory results according to the guidance provided in 
the Clinical Study Protocol
Potential Hy’s Law Criteria met
If the subject does meet PHL criteria the Investigator will:
•
Notify the Sponsor representative who will then inform the central Study Team
The Medical Monitor contacts the Investigator, to provide guidance, discuss, and agree on 
method of follow up and the continuous review of data. Subsequent to this contact, the 
Investigator will:
•
Monitor the subject until liver biochemistry parameters and appropriate clinical 
symptoms and signs return to normal or baseline levels, or as long as medically indicated.
•
Investigate the etiology of the event and perform diagnostic investigations as discussed 
with the Sponsor Medical Monitor.
•
If at any time (in consultation with the Sponsor Medical Monitor) the PHL case meets 
serious criteria, report the event as an SAE using standard reporting procedures.

REVIEW AND ASSESSMENT OF POTENTIAL HY’S LAW CASES
The instructions in this section should be followed for all cases where PHL criteria are met.
No later than 2 weeks after the biochemistry abnormality was initially detected, the Sponsor 
Medical Monitor contacts the Investigator in order to review available data and agree on 
whether there is an alternative explanation for meeting PHL criteria other than DILI caused 
by the study drug. The Sponsor Medical Monitor and other subject matter experts (as 
appropriate) will collaborate in the review and assessment of these cases.
According to the outcome of the review and assessment, the Investigator will follow the 
instructions below.
If there is an agreed alternative explanation for the ALT or AST and TBL elevations, a 
determination of whether the alternative explanation is an AE will be made and subsequently 
whether the AE meets the criteria for an SAE:
•
If the alternative explanation is an AE/SAE, record the AE /SAE in the eCRF according 
to the Sponsor’s standard reporting procedures.
•
If the alternative explanation is not an AE, record the alternative explanation on the 
comment form within the eCRF.
If it is agreed that there is no explanation that would explain the ALT or AST and TBL 
elevations other than the study drug:
•
Report as an SAE (report term “Hy’s Law case”) according to Sponsor standard 
processes
-
The “Medically Important” serious criterion should be used if no other serious criteria 
apply
-
As there is no alternative explanation for the HL case, a causality assessment of 
“related” should be assigned
If, there is an unavoidable delay of over 2 weeks in obtaining the information necessary to 
assess whether or not the case meets the criteria for HL, then it is assumed that there is no 
alternative explanation. Until an informed decision can be made, the following procedure 
should be followed:
•
Report as an SAE (report term “Potential Hy’s Law”) applying serious criteria and 
causality assessment as per above.
Continue follow up and review according to the agreed plan. Once the necessary 
supplementary information is obtained, repeat the review and assessment to determine 
whether HL criteria are met. Update the SAE Report Form according to the outcome of the 
review.
