Safety Measures
Physical examination, vital signs, adverse event (AE) monitoring, serious adverse 
event (SAE) reporting, electrocardiograms (ECGs), and vital status
Statistical Methods
The Full Analysis Set (FAS) is defined as any patient who was randomized in the 
trial and took at least one dose of treatment. Patients will be analyzed according to 
their randomized treatment. 
This study will be completed after 122 patients have an adjudicated MACE.
The primary safety endpoint of time to first MACE will be presented for the FAS 
Population and will be based on on-study analysis. The on-study analysis is 
defined as all events that occurred while the patients was in the study, irrespective 
of treatment exposure (i.e., this includes all events that occurred while a subject 
was on treatment or off treatment, including post treatment follow-up). The time 
to first MACE will be analyzed by means of Cox proportional hazards regression 
model including baseline cardiovascular (CV) severity, smoking status, and 
treatment group as factors. The CV severity at baseline will be defined as 
2 categories: 1) patients who had 2 CV risk factors, and 2) patients who had more 
than 2 CV risk factors or at least one non-fatal stroke or non-fatal myocardial 
infarction. The upper bound of the 95% confidence interval (based on Cox 
regression) for the hazard ratio (aclidinium relative to placebo) of time to first 
MACE will be used to rule out the null hypothesis. If the upper bound of the 95% 
confidence interval is less than the 1.8 margin of the hazard ratio, then the hazard 
ratio of 1.8 or higher will be ruled out. 
The primary efficacy endpoint of rate of moderate or severe COPD exacerbation 
per patient per year during the first year of treatment will be analyzed using 
Negative Binomial regression model. The model will include treatment group, 
baseline ICS use, baseline COPD severity, history of at least one exacerbation in 
the past year and smoking status as factors and the log exposure in years will be 
included as an offset variable. The rate ratio of moderate or severe COPD 
exacerbation per patient per year due to the effect of aclidinium bromide 400 μg 
BID relative to placebo will be estimated along with its confidence interval and 
the corresponding p-value. The two-sided p-value for aclidinium bromide 400 μg 
BID relative to placebo in reducing the rate of exacerbation will be compared to 
the 0.05 significance level.
For this study, a total of 122 MACE will be needed to have 90% power, at 
5% significance level, to rule out a hazard ratio of 1.8 in time to first MACE in 
aclidinium bromide treated patients relative to placebo.
The sample size of 4,000 patients after 1 year of treatment will have ~89% power 
to detect a reduction in the rate of moderate or severe COPD exacerbations per 
patient per year of 14% (rate ratio of 0.86 in aclidinium bromide relative to 
placebo) at 0.05 alpha level. The 89% power was calculated assuming a 
discontinuation rate of 30% during the first year, a placebo rate of 0.8 
exacerbation per patient per year (reduced from 1 to 0.8 as not all patients will 
have a history of exacerbation prior to randomization), and an over-dispersion 
factor of 0.67.

For patients who require a washout, PFTs should be performed to assess patients COPD severity. Patients will then come back in 2 weeks to perform Visit 1A. Patients who 
do not require a washout will sign the ICF and begin the study at Visit 1A.
b
Visit 7, Visit 9, and Visit 11 will occur by telephone. Information regarding AEs, concomitant medications, smoking status, and COPD exacerbations will be collected. The
CAT will also be completed and mailed back to the study site.
c
ICF must be signed at the first visit for all patients prior to performing any study procedure. For patients requiring a washout, ICF must be signed at Visit 0, and then patients 
will return in 2 weeks to perform Visit 1A. ICF must be signed within the 30 days prior to Visit 1A. Rescue medication will only be dispensed after signing the ICF.
d
At Visit 0 for patients who require a washout or at Visit 1A for patients who do not require a washout, patient demographics will be collected to assess eligibility.
e
At Visit 0 for patients who require a washout or at Visit 1A for patients who do not require a washout, medical history will be collected to assess eligibility.
f
At Visit 0 for patients who require a washout or at Visit 1A for patients who do not require a washout, medication history will be collected to assess eligibility.
g
Any adverse event occurring from the time the ICF is signed until 15 days after the last dose of study drug must be recorded. AEs will be collected at Visit 1A for patients 
who completed a Visit 0.  For patients who prematurely discontinue IP, only SAEs (including MACE) will be collected until the last visit/end of study.
h
Although fasting is not required, the patient should be encouraged to fast prior to each visit.  The patient’s fasting condition should be consistent at all visits. For patients 
taking Theophylline, blood serum levels will be measured.
i
Vital signs will consist of pulse rate, systolic and diastolic BP. Pulse and BP will be taken after the patient has been sitting for 10 minutes. Height will only be measured at
Visit 1A and weight will be measured at Visit 1A and Visit 12 or EOT.
j
One ECG will be performed at Visit 1A, and a 2 hour post-dose ECG will be performed at Visit 1B. A 1 hour pre-dose and 2 hour post-dose ECG will be performed at Visits
2, 3, 4, 5, 6, 8, 10 and 12. Patients should be supine for at least 10 minutes before the test is performed. At EOT, only one ECG will be performed.
k
Genitourinary examinations are not required unless medically indicated.
l
For women of childbearing potential, a serum pregnancy test must be performed at Visit 1A and Visit 12 or EOT. A urine pregnancy test will be performed at Visits 6 and 10.
m
Two pre-dose measurements (30-45 mins apart) will be taken at Visits 1B prior to the first dose of IP. At all subsequent visits and EOT, only one measurement will be taken
n
At Visit 1A,  pre- and post-bronchodilator measurements will be performed to assess eligibility. The test will be performed using the rescue inhaler dispensed to the patient 
upon signature of the ICF.  Perform pre-bronchodilator test followed by administration of 4 puffs of bronchodilator (albuterol/salbutamol) with a spacer. Administration of 
bronchodilator can begin as soon as 10 minutes after the completion of the last pre-bronchodilator spirometric effort if the patient is rested and comfortable.
Post-bronchodilator maneuvers will be completed within 10-15 minutes after administration of bronchodilator. 
o
Randomization must occur in  IWRS at Visit 1B within the 3-5 day visit window. All tests/procedures including pre-dose PFTs must be performed, inclusion/exclusion 
verified, and laboratory results reviewed by the PI or medically qualified designee prior to randomization.
p
A paper diary will be used to record IP usage. The paper diary will be reviewed and used to primarily assess compliance at all indicated visits. 
q
Placebo inhaler devices are available for training and practice.
r
IP dispensing will be issued through  IWRS.  
s
IP will be collected at Visits 3, 4, 5, 6, 8, 10, and 12 or EOT.
t
IP compliance will also be measured by dose indicator assessment at Visits 2, 3, 4, 5, 6, 8, 10 and 12 or EOT.
u      Dispense rescue medication diary at Visit 0 for patients who require a washout or at Visit 1A for patients who do not require a washout.  Dispense IP diary at Visit 1B 
(randomization).
v
Visit 1B will be conducted within 3-5 days of Visit A upon receipt of clinical laboratory results. Patient Visit dates for the study will be based on the date of randomization.
w    At Visit 0 PFTs will be performed to assess COPD severity.
x
A telephone contact will be performed 15 days after the last known dose of IP is taken to assess any AEs that may have occurred since the last dose taken at the final visit and 
any changes to or new concomitant medications taken.
.
EOT = End of Treatment; TC = telephone contact

INTRODUCTION
Aclidinium bromide is a long-acting muscarinic antagonist delivered by the Pressair® dry powder 
inhalation device (DPI) for the treatment of bronchospasm in patients with chronic obstructive 
pulmonary disease (COPD).
COPD is a major cause of morbidity and mortality with a high and increasing prevalence, a 
natural history of progressive deterioration, and a loss of pulmonary function characterized by 
incompletely reversible expiratory airflow limitation (Mannino, 2008; Rennard, 1998). The 
characteristic symptoms of COPD include cough, sputum production, and chronic and 
progressive dyspnea. Furthermore, although COPD is primarily a lung disease, it has also 
significant systemic manifestations, which include significant comorbidities such as diabetes, 
cardiovascular (CV) disease, muscle wasting, and bone loss (Global Initiative for Chronic 
Obstructive Lung Disease (GOLD), 2015; Huiart et al, 2005; Soriano et al, 2005; Wouters, 
2002).
Bronchodilators are central to the management of COPD and may be used on an as needed basis 
for acute symptomatic relief or as a maintenance treatment for prevention or reduction of 
symptoms. GOLD recommends regular use of one or more long-acting bronchodilators in 
patients with COPD of at least moderate severity. Currently used bronchodilators include β2-
agonists (short and long acting), anticholinergics (short and long acting), theophylline, or a 
combination of these drugs. The choice of bronchodilator therapy depends on availability and 
individual response in terms of symptom relief and tolerability.  Inhaled corticosteroids (ICS) are 
typically used in patients with more severe disease and/or frequent exacerbations.

INVESTIGATIONAL PLAN
9.1
Overall Study Design and Plan: Description
This study will be a double-blind, randomized, placebo-controlled, parallel-group study to 
evaluate the effect of aclidinium bromide on cardiovascular safety and COPD exacerbations in 
patients with moderate to very severe COPD, as defined by the GOLD criteria (GOLD, 2015).
A total of 4000 patients will be enrolled across approximately 500 study centers. Patients 
meeting entry criteria will be randomized (1:1) to aclidinium bromide 400 μg twice a day (BID) 
or placebo BID with a background of standard of care treatment. Rescue medication 
(albuterol/salbutamol) will be provided for all patients.
The study will consist of a 2 week washout/run-in period followed by a maximum of 36-month 
double-blind treatment period.
Patients on a long-acting muscarinic antagonist (LAMA) (i.e. inhaled anticholinergics) must 
washout 2 weeks prior to randomization. During this time, the patient should be started on 
alternate therapy (e.g., long-acting β2-adrenergic agonist (LABA or LABA/inhaled corticosteroid 
(ICS)) and should be contacted by the PI during the washout period to assess COPD stability. 
AstraZeneca will allow for the reimbursement of background controller medication for patients 
switching their current treatment from a LAMA to an alternate controller medication for patients 
without any healthcare coverage or are not covered by their insurance plan, (e.g., long-acting β2-
adrenergic agonist (LABA or LABA/inhaled corticosteroid (ICS)) when entering the washout 
period and for the duration of the study. 
Patients on a combination of both LAMA and LABA/ICS therapies at washout or screening 
will not be eligible to participate (Section 9.3.2). 
Patients will be assessed according to the Schedule of Evaluations (Section 2).
Patients who prematurely discontinue investigational product (IP) will participate in a post-
treatment follow-up period. The follow-up period will include on-site visits and telephone visits 
to collect MACE, COPD exacerbations, concomitant medications, and SAEs for the remainder 
of the study duration.
This study will conclude when 122 patients have experienced an adjudicated MACE (Section 
9.5.2.10).
9.2
Discussion of Study Design, Including the Choice of Control 
Groups
Aclidinium bromide 400 μg in the Pressair® DPI is approved by the FDA for the long-term 
maintenance treatment of bronchospasm associated with COPD, including chronic bronchitis and 
emphysema.

During the Pulmonary-Allergy Drug Advisory Committee (PADAC) meeting held on February 
23, 2012, the expert panel noted that there is a large population of COPD patients with 
cardiovascular conditions and due to the small number of adverse events (AEs), the impact on 
cardiovascular safety could not be established. Subsequently, Forest Research Institute (IND 
holder when Tudorza® was approved) and the Food and Drug Administration (FDA) agreed that 
a separate study would be needed to conclusively answer the question of cardiovascular safety. 
This study will therefore evaluate MACE and other cardiovascular events of interest for up to 3 
years in patients with moderate to very severe COPD.
Results from the placebo-controlled studies of aclidinium bromide showed significant decreases 
in COPD exacerbations after three and six months of treatment. These data support the 
possibility that moderate to severe COPD exacerbations and associated hospitalizations may be 
reduced in COPD patients who receive longer term treatment with aclidinium bromide in the 
Pressair® DPI. This study is also designed to assess the effect of aclidinium bromide on the 
reduction of COPD exacerbations.
Moreover, this study will also include a health-related quality of life assessment, the COPD 
Assessment Test (CAT) (Jones, 2009).
To qualify for this study, patients must have a clinical diagnosis of moderate to very severe 
COPD, a history of cardiovascular or cerebrovascular disease or cardiovascular risk factors 
and may be treated per current standard of care, including treatment with β-blockers. 
Patients with COPD have a higher risk of acute myocardial infarction (MI), congestive heart 
failure, arrhythmia, and mortality secondary to hospitalization for cardiovascular disease when 
compared to an age- and sex-matched non-COPD population. Results of a longitudinal 
population based study indicate that COPD patients with poor lung function have the highest risk 
of cardiovascular mortality independent of smoking status (Sin et al, 2006). Moreover, it has 
been reported that even modest reductions in lung function increase the risk of ischemic heart 
disease, stroke, and sudden cardiac death 2 to 3 fold independent of other risk factors (Sin et al, 
2003). The patients selected for this study will have lung function < 80% predicted with no 
protocol-required lower limit. In addition, exacerbations have also been associated with 
increased cardiovascular events. Specifically, 1 to 5 days after an exacerbation the risk of MI 
increases 2.7-fold and the risk of stroke increases 1.26-fold 1 to 49 days after a COPD 
exacerbation (Donaldson et al, 2010). Therefore, inclusion of patients with severe to very severe 
lung disease will enrich the population for cardiovascular disease.
COPD is a complex disease involving more than airflow obstruction. The increased circulation
inflammatory mediators in response to inflammation and/or alterations in repair mechanisms 
may result in systemic manifestations or worsening of co-morbid diseases such as ischemic heart 
disease and heart failure (Barnes et al, 2009). Therefore, it is anticipated that the occurrence of 
MACE will be achieved in the proposed COPD patient population given the Inclusion/Exclusion 
Criteria (Section 9.3), specifically those patients with a history of cardiac disease/risk factors.

follow-up period.
9.3.3
Removal of Patients from Treatment and Study Conduct  
9.3.3.1
Removal of Patients from Investigational Product
Discontinuation of IP does not necessarily mean discontinuation of follow-up or termination of 
study participation. Compliant subjects who are discontinued from the IP should be encouraged 
to continue to undergo all study related visits/procedures for the full 36-months study period in 
order to support the final efficacy and safety analysis for aclidinium bromide. The reason for 
premature discontinuation of IP will be documented in the source documentation. It is essential 
to collect as much data as possible for all subjects throughout the study and especially all 
potential endpoint events. Complete withdrawal from the study (i.e., withdrawal of consent) has 
a direct negative impact on the potential validity of all study data and should be avoided 
wherever possible.
The post-treatment follow up period will include assessments at on-site visits and telephone 
visits to collect MACE, COPD exacerbations, concomitant medications, and SAEs for the 
remainder of the study duration.
After this period, the subjects will perform the EOT visit as described above. As per
Section 9.5.5.9, randomized patients who prematurely discontinue IP will enter into a post-
treatment follow-up period alternating telephone contacts and on-site visits (Table 9.3.3–1).
Patients who experience a MACE must be discontinued from IP and enter into the post-treatment 
follow-up period.
Patients can also be prematurely discontinued from IP and enter into the post-treatment follow-
up period for one of the following reasons:
!
Adverse event 
!
COPD exacerbation

!
Insufficient therapeutic response
!

If IP is temporarily suspended (for any reason) for more than 30 consecutive days or a total of 
60 aggregate days within the previous 6 months, the patient must be permanently discontinued 
from study drug and enter into the post-treatment follow-up period.
If the EOT visit occurs within 2 weeks of the next scheduled visit (TC or on-site), then the next 
visit can be skipped.
For unforeseen circumstances (e.g., patients move), post-treatment follow up period phone calls 
may be conducted in lieu of on-site visits, however, this must be pre-approved by the Sponsor.

End of Treatment IP Collection
If IP dosing is interrupted (for any reason) for more than 30 consecutive days or a total of 
60 aggregate days within the previous 6 months, the patient must be discontinued from study 
drug and enter into the post-treatment follow-up period. 
Marketed albuterol (108 μg per puff) or salbutamol sulfate (100 μg/puff), supplied by AZ, will 
be the only rescue medication permitted during the IP treatment period of the study. The 
investigator or designee will provide the patient with this medication upon signing the ICF at 
Visit 0 or Visit 1B and at other visits as necessary according to use. Rescue medication will be 
provided by AZ during the study treatment period and the post-treatment follow-up period 
(Section 9.3.3.1). Rescue medication will be provided locally for all visits (except for visit 1A in 
the US where Albuterol for reversibility testing will be assigned to the patient via IWRS).
At Visit 1A (for patients who do not require a washout), 4 puffs of albuterol or salbutamol from 
the dispensed rescue inhaler should be given with a spacer device (AeroChamber Plus) to ensure 
proper inhalation. During the study, the use of spacers for albuterol/salbutamol administration is 
not required. If a spacer is used, it must be used consistently throughout the study at each visit.  
Albuterol/salbutamol should be discontinued at least 6 hours before all visits (including Visit 0 
and Visit 1A) and not used again until after the completion of the last study measurement of the 
visit. Rescue medication should only be used during a visit if absolutely necessary. 
9.4.2
Identity of Investigational Product(s)
IP will be identified with the protocol number, kit number, and inhaler number and labelled with 
storage information, warning language (“Caution: New Drug - Limited by Federal Law to 
Investigational Use”), space for the coordinator to write in the visit number, and instructions for 
using the inhaler as directed. Immediately before dispensing IP, the study coordinator will write 
on the label of the kit and the pouches the PID number, the patient’s initials, the visit number, 
and the date dispensed. Labelling will be provided in the local language, and specific language 
related to local laws will be included.
Double-blind IP will be prepared according to the randomization list. Each manufacturing 
process will be performed and documented in conformity with good manufacturing practices. 
Placebo Pressair™devices for training purposes will also be supplied and identified accordingly.

The IP should be stored at 25°C (77°F); in accordance with instructions given on the IP label, the 
range of 15°C to 30°C (59°F-86°F) should not be exceeded. All IP must be stored in an 
appropriate, secure area (e.g., a locked cabinet in a locked room).
The PI is responsible for recording the receipt and use of all IP supplied and for ensuring the 
supervision of the storage and allocation of these supplies. All unused IP must be returned; and, 
whenever IP is returned, unit counts must be performed. All IP must be accounted for. All 
unused IP and empty IP packages in US/Canada, following approval by AZ, should be destroyed 
unless otherwise instructed. 
9.4.3
Method of Assigning Patients to Treatment Groups
After a patient signs the ICF at the first screening visit, study personnel will register the patient 
in the interactive web response system (IWRS), and the system will assign the patient a 
sequential PID number. The first patient to sign the ICF at each site will be assigned the first 
number in the sequence by the system. The PID number will consist of nine digits: the first four 
will represent the study center (0101, 0202, etc), followed by the two digit study number (45) 
and a three digit screening number (001, 002, etc). As an example, at site number 0101, 
performing protocol number 45, the sequence of numbers for that site will be 
 
, etc. This PID number will be used to identify the patient throughout the 
study (i.e., at all study phases).
The study center must contact the IWRS at screening and at all subsequent study visits in order 
to obtain the kit number to be dispensed to the patient at that visit.
Confirmation of the IP and number will be faxed or e-mailed (per the study center’s preference) 
to the study center following each assignment. A detailed description of IWRS procedures is 
contained in the IWRS Manual in the Study Reference Binder.
9.4.4
Selection of Dosages in the Study
The aclidinium bromide dosage chosen for this study is based on the 400 μg BID dose currently
approved by the FDA for the long-term maintenance treatment of bronchospasm associated with 
COPD, including chronic bronchitis and emphysema. 
9.4.5
Selection and Timing of Dose for Each Patient
The first dose of IP will be administered at Visit 1B after pre-dose PFT measurements under the 
supervision of study staff. IP will continue to be taken twice daily approximately 12 hours apart. 
The morning dose of IP will be taken prior to 11:00 AM throughout the study. On visits where 
trough FEV1 is measured, the last dose of IP must be taken 12-14 hours prior to the study visit.  
At Visit 1B, following randomization, the PI, or a qualified designee, should make sure the 
patient understands the instructions and the correct use of the study medication IP inhaler. 
Patients will be provided with verbal and written instructions.
At each visit, the PI will ensure that the patient is properly using the study medication IP inhaler; 
reinstruction will follow when needed (the training device may be used again if appropriate).

Blinding
A list of patient randomization codes will be generated by Statistical Programming at AZ and 
implemented by the IWRS vendor (an electronic version will be stored on a secure server). This 
list will identify each patient by randomization number and include the patient’s corresponding 
treatment assignment.
9.4.7
Unblinding
Any unblinding at the study site level should be done only in an emergency that requires the IP 
to be identified for the medical management of the patient. The PI has to notify the study 
physician immediately and a full written explanation will be provided if the blind is broken. 
Before IP is unblinded, every attempt should be made to discuss the case with the Study 
Physician. Breaking the code at the study center will immediately disqualify the patient from 
further participation in the study; however, the patient should enter into the post-treatment 
follow-up period.
Treatment codes may be broken by Global Patient Safety at AZ for regulatory reporting 
purposes. In such cases, the study staff will be kept blinded and the patient will not need to be 
disqualified from the study.
In an emergency, the PI can obtain the treatment assignment of any patient at his or her study 
center through the IWRS. In an emergency, the PI will access the IWRS to break the blind.
9.4.8
Prior and Concomitant Therapy
A list of medication classes that are allowed and not allowed as concomitant medications for 
either episodic or chronic use is provided in Appendix II. Medications taken during the previous 
15 days will be recorded at Screening (Visit 1A) and /Baseline (Visit 1B) in the eCRF. 
Thereafter, any changes in concomitant medications or new medications added will be recorded 
in the eCRF.
9.4.9
Monitoring Treatment Compliance
Compliance will be monitored primarily by paper diary review. Treatment compliance based on 
the diary will be recorded in the eCRF.
Dose counter indicator will act as a secondary measure of compliance. 
Before new IP is dispensed at each visit, every effort will be made to collect all unused IP.
9.4.10
Medication, Dietary, and Activity Restrictions Before Study Visits
The following are prohibited within the times indicated before any study visit:
!
Vigorous physical activity should be avoided for at least 20 minutes before each visit
!
Alcohol consumption should be avoided at least 4 hours before each visit
!
The intake of caffeinated products (e.g., coffee, tea, soda) will not permitted for at least 6 
hours before each visit until completion of all procedures on that day

Efficacy and Safety Variables
9.5.1
Efficacy Assessment(s)
COPD exacerbations will be assessed in this study.
9.5.1.1
Primary and Secondary Efficacy Assessment(s)
The primary efficacy endpoint is the rate of moderate to severe COPD exacerbations per patient 
per year during the first year of treatment.
COPD exacerbations will be evaluated by the PI throughout the study.
The onset and end of an exacerbation is defined by the investigator in their assessment of patient 
symptoms and initiation/finalization of treatment (as defined below for the severity of 
exacerbation). 
The severity of a COPD exacerbation is to be assessed according to the following scale:
Mild:
Increase in COPD symptoms (e.g., dyspnea, cough, sputum volume, sputum 
purulence) during at least 2 consecutive days, managed by the patient at home by 
increasing short-acting bronchodilator and/or ICS use
Moderate:
Increase in COPD symptoms (e.g., dyspnea, cough, sputum volume, sputum 
purulence) during at least 2 consecutive days that does not lead to hospitalization 
but is treated with antibiotics and/or systemic corticosteroids
Severe:
Increase in COPD symptoms (e.g., dyspnea, cough, sputum volume, sputum 
purulence) during at least 2 consecutive days that leads to hospitalization 
(overnight stay at hospital or emergency room) or death
The interval between 2 consecutive COPD exacerbations must be at least 7 days. Therefore, if 2 
COPD exacerbations occur within 7 days of each other, it will be considered as 1 event.
Patients who experience a moderate COPD exacerbation may be treated with the addition of an 
allowed concomitant medication and remain on IP at the discretion of the PI.

Amended Protocol LAS-MD-45 Amendment 5

AstraZeneca
Final
30 Aug 2017
Patients who experience a severe or recurrent COPD exacerbation may be treated with the 
addition of an allowed concomitant medication and remain on IP at the discretion of the PI.
Patients who experience a severe or recurrent COPD exacerbation and require treatment with a 
LAMA, must be discontinued from IP and enter into the post-treatment follow-up period 
(Section 9.3.3.1).
The secondary efficacy endpoint is the rate of hospitalizations due to COPD exacerbations per 
patient per year during the first year of treatment.
9.5.1.2
Additional Efficacy Assessment(s)
a)
Spirometry
One pre-bronchodilator and one post-bronchodilator measurement will be taken at Visits 1A, and 
two pre-dose measurements at Visit 1B.  The assessment of morning pre-dose trough FEV1 will 
be obtained at Visits 2, 3, 4, 5, 6, 8, 10, and 12 or EOT.
Measurements to assess eligibility will be taken at Visit 1A. All spirometry results will be 
transferred via ndd Easy One Spirometer on a monthly basis. Data transfers (values will include: 
PFT assessment date, time, timepoint, the ATS/ERS criteria met or not, FEV1, percentage 
predicted FEV1, FVC, percentage predicted FVC, FEV1/FVC ratio, indication of the best effort 
evaluation per ndd Easy One Spirometer has met ATS/ERS grading) selected to assess Inclusion 
Criteria (Section 9.3.1)
All spirometry assessments (up to a maximum of 8 PFT maneuvers) will be performed, recorded 
locally, and will be read by a central vendor (see Appendix III).
The data for each visit must be entered into the electronic data capture system, including patient 
ID, date, time, visit number, whether spirometry was performed, whether the patient had a 
bronchodilator in the previous 6 hours, and the reason for visit, if it was unscheduled.
The values for the maneuvers using the sponsor provided ndd Easy One Spirometer will not be 
entered into the eCRF page anymore, this data will be collected via the ndd Easy One Spirometer 
and transmitted to the central vendor. 
The maneuvers must be reviewed by the PI or qualified designee to ensure ATS/ERS criteria for 
acceptability and repeatability have been met.  
b)
COPD Assessment Test (CAT)
Refer to Section 9.5.4, Health Economics and Outcomes.
9.5.2
Safety Assessments
Patients must be seen by a physician or an appropriately trained health professional at every visit 
and the evaluation must be documented. The procedures discussed below will be completed at 
the designated visits.

9.5.2.1
Adverse Events
An AE is any untoward medical occurrence in a patient or clinical investigation patient 
administered a pharmaceutical product and which does not necessarily have to have a causal 
relationship with this treatment. An AE can therefore be any unfavorable and unintended sign 
(including an abnormal laboratory finding), for example, symptom, or disease temporally 
associated with the use of a medicinal product, whether or not considered related to the 
medicinal product (ICH-E2A).
For the purpose of data collection for this study, any untoward event that was reported from the 
time the patient signed the ICF until 15 days after the last dose of treatment are to be considered 
AEs. For patients who prematurely discontinue study drug and enter post-treatment follow-up 
period, SAEs (including MACE) will be collected until end of study.
Examples of AEs are as follows:
!
Changes in the general condition of the patient
!
Subjective symptoms offered by or elicited from the patient
!
Objective signs observed by the PI or other study center personnel
!
All diseases that occur after signing ICF, including any change in severity or frequency of 
preexisting disease
!
All clinically relevant abnormalities in laboratory values or clinically relevant physical 
findings that occur during the study schedule
Please note medical procedures scheduled prior to consenting, but occurring during the study 
should not be captured as AEs, but should be listed in the medical history if related to a pre-
existing condition.
9.5.2.2
Causality Assessment
For all AEs, the PI must provide an assessment of causal relationship to the investigational 
product. The causality assessment must be recorded on the appropriate AE reporting page of the 
patient’s eCRF. Causal relationship must be assessed by answering the following question:
Is there a reasonable possibility the investigation product caused the event?
Yes:
There is evidence to suggest a causal relationship between the investigational product and 
adverse event; i.e.:
# There is a reasonable temporal relationship between the investigational product and the 
event, and
# The event is unlikely to be attributed to underlying/concurrent disease, other 
investigational products, or other factors, and/or

Final
30 Aug 2017
# Positive dechallenge and/or rechallenge exist
No:
There is no evidence to suggest a causal relationship between the investigational product 
and adverse event; i.e.:
# There is no reasonable temporal relationship between the investigational product and the 
event, or
# The patient did not take the investigational product, or
# The event is likely to be attributed to underlying/concurrent disease, other investigational 
products, or other factors, or
# The event is commonly occurring in the (study) population independent of investigational 
product exposure
9.5.2.3
Severity Assessment
The PI will provide an assessment of the severity of each AE by recording a severity rating on 
the appropriate AE reporting page of the patient’s eCRF. Severity, which is a description of the 
intensity of manifestation of the AE, is distinct from seriousness, which implies a patient 
outcome or AE-required treatment measure associated with a threat to life or functionality 
(Section 9.5.2.4). Severity will be assessed according to the following scale:
Mild:
Minor awareness of signs or symptoms that are easily tolerated without specific 
medical intervention
Moderate:
Discomfort that interferes with usual activities and may require minimal 
intervention
Severe:
Significant signs or symptoms that are incapacitating with an inability to work or 
perform routine activities and/or that require medical intervention
9.5.2.4
Serious Adverse Events
A serious adverse event is any untoward medical occurrence that at any dose:
!
Results in death
!
Is life threatening
!
Requires inpatient hospitalization or prolongation of existing hospitalization
!
Results in persistent or significant disability/incapacity,
!
Is a congenital anomaly/birth defect, or
!
Important medical event

Amended Protocol LAS-MD-45 Amendment 5
Page 33
AstraZeneca
Final
30 Aug 2017
Important medical events that may not result in death, be life threatening, or require 
hospitalization may be considered serious when, based on appropriate medical judgment, they 
may jeopardize the patient or subject and may require medical or surgical intervention to prevent 
one of the outcomes listed in this 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 patient hospitalization, or the development of investigational 
product dependency or drug abuse.
Emergency room visits that do not result in hospitalization should be evaluated for one of the 
other serious outcomes to determine whether they qualify as SAEs.
Preplanned hospitalizations (e.g., elective procedures for preexisting conditions that did not 
worsen, such as cosmetic surgery and hysterectomy) are excluded from SAE reporting.
The following events are captured as efficacy endpoints and are therefore excluded from 
AE/SAE reporting:
!
COPD exacerbation
!
Signs and symptoms associated with COPD exacerbation
!
COPD exacerbation resulting in hospitalization and/or death
For the purpose of data collection for this study, any SAE must be reported from the time the 
patient signed the ICF until 15 days after the last dose of study drug.
9.5.2.5
Reporting Adverse Events and Serious Adverse Events
Any untoward event that occurs in a patient from the time he or she signs the ICF for the trial 
until 15 days after the last dose of investigational product has to be collected. Thus, any 
untoward medical occurrences or unfavorable and unintended signs, symptoms, or diseases that 
occur in the pretreatment, in treatment, or post treatment period are to be considered AEs and/or 
SAEs, and consequently recorded and reported as such. For patients who prematurely 
discontinue study drug and enter post-treatment follow-up period, SAEs (including MACE) will 
be collected until end of study.
At each visit, patients are to be queried regarding any AEs or SAEs that have occurred since the 
previous visit. Patients will be asked to volunteer information with a nonleading question such 
as, “How do you feel since your last visit?” Study center personnel will then record all pertinent 
information in the patient’s eCRF. 
Follow-up of unresolved adverse events:
Any AEs that are unresolved at the patients last visit are followed up by the Investigator for as 
long as medically indicated, but without further recording in the CRF. AZ 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.

All AEs must be recorded on the appropriate AE reporting page of the patient’s eCRF whether or 
not they are considered causally related to the investigational product.
For every AE, the PI must:
!
Provide an assessment of the severity, causal relationship to the investigational product, and 
seriousness of the event (e.g., SAE)
!
Document all actions taken with regard to the investigational product
!
Detail any other treatment measures taken for the AE
Additional information regarding the immediate reporting required for SAEs is provided in 
Section 9.5.2.6.
9.5.2.6
Immediate Reporting of Serious Adverse Events
The Sponsor is required to inform worldwide regulatory authorities of SAEs that meet specific 
criteria. Therefore, the Sponsor must be notified immediately regarding any SAE that occurs 
after informed consent is obtained. All SAEs will be recorded in the eDC.
Within 24 hours of learning of any AE that meets one of the criteria for an SAE, the study center 
personnel must report the event to the appropriate AZ representative. The designated AZ 
representative works with the Investigator to ensure that all the necessary information is 
provided to the AZ Patient Safety data entry site within 1 calendar day of initial receipt for fatal 
and life threatening events and within 5 calendar days of initial receipt for all other SAEs.
For fatal or life-threatening adverse events where important or relevant information is missing, 
active follow-up is undertaken immediately.  Investigators or other site personnel inform AZ 
representatives of any follow-up information on a previously reported SAE within one calendar 
day i.e., immediately but no later than 24 hours of when he or she becomes aware of it.
Once the Investigators or other site personnel indicate an AE is serious in the electronic data 
capture (eDC) system, an automated email alert is sent to the designated AZ representative.
If the eDC system is not available, then the Investigator or other study center personnel reports a 
SAE to the appropriate AZ representative by fax.
The AZ representative will advise the Investigator/study center personnel how to proceed. 
The AZ paper SAE Report Form should be faxed to the designated AZ representative using the 
country specific number below. 
For U.S: Fax number 
For Canada: Fax number 
The AstraZeneca representative will advise the Investigator/study center personnel how to 
proceed. As soon as the eDC is available data should be re-entered into the system. If, during

follow-up, any non-serious AE worsens and eventually meets the criteria for an SAE, that AE 
should be recorded as a new SAE. 
NOTE: For any follow up information pertaining to SAEs occurring prior to the implementation 
of the updated eDC the information must be faxed to an AZ representative using the process 
described above. No information should be entered into the eDC.
9.5.2.7
Overdose
Overdose only needs to be reported if leading to an Adverse Event. If the overdose leads to an
Adverse Event meeting the criteria of seriousness (SAE), the SAE module must be completed
within the same timeframe and following the same routing as for a SAE (see section 2.1 ). The
patient must be followed-up and the investigator will make every effort to obtain information on
how the overdose was managed, any treatment administered and the final outcome. This
information will be reported, following the same procedure and timeframes as for the initial 
report.
9.5.2.8
Exposure to Investigational Product During Pregnancy
Study center personnel must report every pregnancy from the time he or she signs the ICF for the 
trial until the patient’s last visit as soon as possible (within 24 hours of learning of the 
pregnancy) to the appropriate AZ representative. 
The designated AZ representative will work with the Investigator to ensure that all relevant 
information is provided to the AZ Patient Safety data entry site within 1 or 5 calendar days for 
SAEs (see Section 9.5.2.8) and within 30 days for all other pregnancies. The same timelines 
apply when outcome information is available.
The PREGREP module in the CRF is used to report the pregnancy and the PREGOUT is used to 
report the outcome of the pregnancy.
Pregnancy of the subject’s partners is not considered to be an adverse event. However, the 
outcome of all pregnancies (spontaneous miscarriage, elective termination, ectopic pregnancy, 
normal birth or congenital abnormality), occurring from the date of the first dose until last visit, 
if possible, be followed up and documented.
9.5.2.9
Potential Hy’s Law Cases
Study center personnel must report every patient that meets potential Hy’s law criteria, i.e.:
!
ALT or AST ≥ 3xULN AND
!
Total Bilirubin ≥ 2xULN AND
!
Alkaline Phosphatase < 2xULN
Within a 24 hour period that occurs anytime from the time he or she signs the ICF for the trial 
until 15 days after the last dose of investigational product. A potential Hy’s law should be 
reported as an SAE using the most relevant SAE criteria, as judged by the Investigator (see 

Amended Protocol LAS-MD-45 Amendment 5

Section 9.5.2.5). Every effort to determine the cause of the liver enzyme abnormalities must be 
made, and close monitoring should be initiated in conjunction with the study physician.
Additionally, if a patient meets the above criteria, the presence or occurrence of any of the 
following will be collected in the eCRF:
!
Abnormal liver biochemistry risk factors (e.g. alcohol abuse, increased alcohol consumption 
within 1 month of a Hy’s Law event, IV drug use, tattoo, acupuncture, sexually transmitted 
disease, toxic/chemical agent exposure, travel to areas at risk, post-partum, parenteral 
nutrition, excessive physical exercise, changes in diet, fasting episode, weight loss, previous 
drug reaction associated with an elevation of liver tests, blood transfusion, exposure to 
anyone with known hepatitis, history of hypotension/shock, history of hepatitis C, history of 
hepatitis B, history of hepatitis A, history of hepatitis E, history of nonalcoholic 
steatohepatitis, Wilson’s disease, history of diabetes, hemochromatosis, history of α-
1antitrypsin disease, history of Gilbert’s disease, known hepatic congestion, cirrhosis, 
esophageal varices, GI bleeds, recent use of Tylenol/hepatotoxic drugs, and any other 
relevant abnormal liver biochemistry risk factors)
!
Liver disease signs and symptoms (e.g. anorexia, asthenia, pyrexia, pruritus, jaundice, 
arthralgia, abdominal pain, abdominal tenderness, nausea, vomiting, mucosal inflammation, 
purpura, hepatomegaly, hepatojugular reflux, splenomegaly, elevated jugular venous 
distension, ascites, confusional state/encephalopathy, coma, right upper quadrant pain, 
vascular cutaneous signs, and any other relevant signs and symptoms)
!
Liver diagnostic tests (e.g. ultrasound RUQ, abdomen CT, liver MRI/MRCP, endoscopic 
retrograde cholangiopancreatography/esophagogastroduodenoscopy, liver biopsy, x-ray, and 
paracentesis) 
9.5.2.10
Major Adverse Cardiovascular Events
The primary safety endpoint is time to first MACE.
MACE is a composite of the total of CV death, non-fatal MI and non-fatal stroke. 
A Clinical Events Committee (CEC) will be formed to assess and adjudicate all MACE. This 
committee will be blinded to treatment assignment and composed of independent cardiologists. 
A charter outlining the communication flow and the criteria to classify and adjudicate MACE 
will be established.
The committee will adjudicate:
!
All death cases 
!
Myocardial infarction defined as any non-fatal case that was coded to a preferred term (PT) 
in the standardized MedDRA query (SMQ) “myocardial infarction” 
!
Stroke defined as any non-fatal case that was coded to a PT in the SMQ “central nervous 
system hemorrhages and cerebrovascular conditions”

Additionally, the SMQs of cardiac disorders and cerebrovascular disorders will also be assessed 
by the CEC.
Patients who experience a MACE must be discontinued from IP and enter into the post-treatment 
follow-up period (Section 9.3.3.1).
Rescue medication use will be collected in the patient diary to assist in the interpretation of 
patient level safety events, such as MACE or other cardiovascular events.  In the event of a 
MACE or other cardiovascular event, copies of the paper diary may be requested by the Sponsor.
9.5.2.11
Clinical Laboratory Determinations
Blood and urine samples for clinical laboratory tests will be collected at Visits 1A, 6, 10, and 12 
or EOT, for patients who prematurely discontinue IP. At Visit 1B, the PI will assess the clinical 
significance of any values outside the reference ranges provided by the local laboratory.
Although fasting is not required, the patient should be encouraged to fast prior to each visit.  The
patient’s fasting condition must be consistent at all visits.
Women of childbearing potential will be required to have a serum pregnancy test at Visit 1A and 
Visit 12 or EOT, for patients who prematurely discontinue IP. For Visits 6 and 10, a urine 
pregnancy test will be performed for women of childbearing potential.
The following clinical laboratory tests will be performed:
Hematology:
Absolute and differential blood count (neutrophils, lymphocytes, 
monocytes, eosinophils, and basophils), white blood cell count, 
erythrocyte count, thrombocytes (platelets), hemoglobin, and hematocrit
Chemistry:
Sodium, potassium, calcium, chloride, glucose, blood urea nitrogen, 
creatinine, total protein, alkaline phosphatase, albumin, total bilirubin, 
aspartate aminotransferase, creatine kinase, inorganic phosphorus, alanine 
aminotransferase, total cholesterol, triglycerides, uric acid, 
gamma-glutamyl transferase, and lactate dehydrogenase
Urinalysis:
Dipstick analysis will be performed at the center and will include: pH, 
blood, leukocytes, protein, glucose, bilirubin, ketones, and nitrites. If urine 
dipstick is abnormal, a urine sample will be sent to local lab for analysis of 
the sediment
Theophylline:
Only if the patient is receiving theophylline
Local laboratories will be used to evaluate all urine and blood samples.
Clinically significant abnormalities in laboratory values as determined by the investigator should 
be reported as adverse events (Section 9.5.2.1).

Vital Signs
Vital sign measurements will be documented at Visits 1A, 2, 3, 4, 5, 6, 8, 10, and 12 or EOT, for 
patients who prematurely discontinue IP. The parameters are pulse rate, sitting systolic and 
diastolic blood pressure (BP). Pulse and BP readings will be taken after the subject has been 
sitting for 10 minutes. Waist circumference will also be taken at Visit 1A according to guidance 
provided by the National Heart, Lung, and Blood Institute (NHLBI 2000) (See Appendix VI). 
9.5.2.13
Electrocardiograms
One 12-lead electrocardiogram (ECG) will be performed at Visit 1A, and 2 hour post-dose ECG 
will be performed at Visit 1B.
An ECG will be performed 1 hour pre-dose and 2 hours post-dose at Visits 2, 3, 4, 5, 6, 8, 10 and 
12.  For patients who prematurely discontinue IP (EOT Visit), one ECG assessment will be 
performed.  Patients should be in a supine position for at least 10 minutes prior to the test.  All 
ECGs will be read by a central vendor.  
If a clinically significant ECG abnormality persists, the PI must contact the study physician to 
determine whether the patients should be continued in the study. 
The time window for ECGs to be completed is ±10 minutes from the scheduled time point.
9.5.2.14
Other Safety Assessments
a)
Physical Examination
A physical examination will be done at Screening (Visit 1A) and Visits 4, 6, 10, and 12 or EOT 
by a professionally trained physician or health professional listed on Form FDA 1572 and 
licensed to perform physical examinations. Height will be collected only at Visit 1A. Body 
weight will be collected at Visit 1A and Visit 12 or EOT. If a clinically significant finding occurs 
at Visit 1A, it should be added to the Medical History and any changes thereafter considered 
AEs.
9.5.2.15
Data Safety Monitoring Board
An independent Data Safety Monitoring Board (DSMB) will be established for this study. The 
DSMB will periodically monitor and review relevant clinical safety data, including adjudicated 
MACE.
DSMB members comprise a multidisciplinary team, including experts in pulmonary disease, 
cardiovascular disease, and biostatistics. Ad hoc members from other disciplines may be 
appointed to the DSMB if deemed necessary by the DSMB Chair and the Sponsor.
Membership and responsibilities of the DSMB as well as meeting frequencies and other details 
(e.g. communication) will be defined in the DSMB charter.
9.5.2.16
Joint Advisory Committee   
The purpose of the ASCENT COPD Joint Advisory Committee (JAC) is to advise the Sponsor 
Study Team regarding issues related to the conduct of the study (e.g. global enrollment rate,

Not applicable.
9.5.4
Health Economic and Outcomes Research Assessments
The CAT is a validated, patient completed, questionnaire to measure the impact of COPD on a 
patient’s health status. It is comprised of 8 questions to be answered independently by patient via 
a paper questionnaire (See Appendix V). At Visits 1B, 3, 4, 5, 6, 8, 10 and 12 or EOT, the CAT 
will be completed at the study site prior to any other study procedures. At Visits 7, 9 and 11, the 
CAT will be completed at home by the patient during the telephone visit and mailed back to the 
study site.  All data captured on the CAT will be entered into EDC by site staff.

Data Quality Assurance
9.6.1
Data Monitoring
Before any patient enters the study, a representative of Sponsor, will meet with the PI and the 
study center staff to review the procedures to be followed during the study. Electronic data 
capture (EDC) functionality training is provided via computer-based training to train PIs and 
authorized designees on recording the data in the eCRFs using the electronic data capture EDC 
system. After the first patient is enrolled, the Sponsor representative, a Regional Site Manager 
(RSM) or designee, will periodically monitor the progress of the study by conducting on-site 
visits. This RSM or designee will review query statuses remotely, possibly warranting more 
frequent communication and/or site visits with the PI and the study center staff. The PI will make 
available to the RSM or designee source documents (written notes and medical records/ 
electronic medical records), signed consent forms, and all other study-related documents. The PI 
and the study center staff will be responsible for data entry of patient data into the eCRFs via the 
EDC system, resolving data queries generated via the EDC system and providing missing or 
corrected data. The PI or designee will be responsible for approving all changes performed on 
the data, and endorsing the patient data within the EDC system. This approval method will 
include applying an electronic signature linked to a uniquely assigned username and password 
that together will represent a traditional handwritten signature used in the past.
9.6.2
Data Recording and Documentation
Data collection will involve the use of the AZ EDC system, to which only authorized personnel 
will have access. Patient’s data are to be entered into the EDC system by the PI or designee using 
their assigned EDC user account. After data entry into the EDC system by the PI or designee, a 
combination of manual and programmatic edit checks will be used to review the data for 
completeness, logic, and adherence to study protocol. As a result of these edits checks, data 
monitoring and reviews; queries may be electronically issued to the study centers and should be 
answered electronically via the EDC system.

Each query will carry identifying information (assigned username, date and time) to assist AZ 
and the PI on the origin of the data clarification request and the response provided by the PI. All 
data changes made to the patient’s data via a data query will be approved by the PI prior to final 
database lock.
After all data have been reviewed and all issues have been resolved, the database will be locked.
All data collected in the context of this study will be stored and evaluated per regulatory 
requirements and applicable guidance for electronic records. Also, data will be stored and 
evaluated in such a way as to guarantee patient confidentiality in accordance with the legal 
stipulations applying to confidentiality of data. Study records (e.g., copies of eCRFs, laboratory 
reports, patient diaries, regulatory documents, etc.) will be retained at the study center, along 
with adequate source documentation, according to FDA and ICH requirements. All study records 
must be available for inspection by Sponsor; its authorized representatives; and the FDA or other 
health authorities.
9.7
Statistical Methods and Determination of Sample Size
9.7.1
Patient Populations
Three populations will be considered in the statistical analysis of the study.
9.7.1.1
Screened Population
The Screened Population will consist of all patients who signed a written informed consent form 
and received a screening number.
9.7.1.2
Randomized Population
The Randomized Population will consist of all patients in the Screened Population who were 
randomized to a treatment group in the study.
9.7.1.3
Full Analysis Set Population
The Full Analysis Set (FAS) population will consist of all patients in the Randomized Population 
who took at least one dose of double-blind investigational product. Patients will be analyzed 
according to their randomized treatment.  
The FAS will be used to carry out the primary analysis of both efficacy and safety data. Efficacy 
and safety data may be further investigated and sensitivity analyses may be performed using the 
Randomized Population if more than 1% of patients did not receive one dose of double-blind IP. 
9.7.2
Patient Disposition
The number of patients in Randomized, and FAS populations will be summarized by treatment 
group and study center; the Screened Population will only be summarized overall by study 
center.

Screen failures (i.e., patients screened but not randomized) and the associated reasons for failure 
will be tabulated overall. The number and percentage of patients who complete the double-blind 
treatment period, who prematurely discontinue from IP, and who prematurely discontinue from 
the study during the same period will be presented for each treatment group and pooled across 
treatment groups for the FAS Population. The reasons for premature discontinuation as recorded 
on the termination pages of the eCRF will also be summarized (number and percentage) by 
treatment group for all randomized patients.
The percentage of premature discontinuations from the study treatment as well as from the study 
will be compared overall using Kaplan Meier and Log rank test. Each discontinuation reason will 
be summarized by treatment groups. Additional graphical presentation to illustrate patterns of 
missing data will be described in the Statistical Analysis Plan.
Handling professional/duplicate patients. Professional patients are individuals who, in 
violation of protocol entrance criteria enter into the same study more than once and/or enter into 
different studies at the same time. 
Unless otherwise stated, the first incidence of patient entering trial is used in analysis and 
summary. All data is listed for transparency, with flags for duplicate patients to ensure clarity on 
the records included/excluded from the analysis.
For handling of AEs, if a patient is randomized to same treatment arm, all data will be included 
into the analysis. If patient is randomized to a different treatment (i.e., different treatment 
received at the second incidence vs the first incidence), only the data from the first incidence will 
be used in analysis.
9.7.3
Demographics and Other Baseline Characteristics
Demographic parameters (including age, age group [≥ 40 and < 60, ≥ 60 and < 70, and ≥ 70 
years old], race, ethnicity, sex, weight, height, and body mass index) and other baseline 
characteristics (including duration of COPD in years; patient known to have either chronic 
bronchitis or emphysema; COPD exacerbation in the previous 12 months; number of COPD 
exacerbations in the previous 12 months; COPD severity according to degree of airway 
obstruction: grade I [mild], II [moderate], III [severe], or IV [very severe]; smoking status and 
history; smoking duration in years; number of cigarettes per day; total pack-years; FEV1, FEV1
% predicted, FVC, and FVC % predicted prebronchodilator test; FEV1, FEV1 % predicted, FVC, 
and FVC % predicted, and ratio of FEV1/FVC postbronchodilator tests; % bronchodilator 
reversibility; change from prebronchodilator FEV1 to postbronchodilator FEV1; reversibility and 
baseline FEV1) will be summarized by treatment group for the FAS populations. For continuous 
variables, the number of nonmissing observations, mean, SD, median, minimum, and maximum 
will be presented. No statistical tests will be performed.

The World Health Organization Drug Dictionary, enhanced version of March 2011 or newer, 
will be used to classify prior and concomitant medications by therapeutic class. Prior medication 
is defined as any medication taken within the period from 15 days before Screening (V0/Visit 
1A) to the day before the first dose of double-blind IP. Concomitant medication is defined as any 
medication taken during the double-blind treatment period between the date of the first dose of 
IP and the date of the last dose of IP, inclusive.
Prior medications will be tabulated by Anatomical Therapeutic Chemical classification code, 
preferred name, and treatment group. In addition, the number and percentage of patients who 
used any prior medication for COPD will be presented by therapeutic categories (i.e., Long-
Acting β2-Agonists [LABA], Long-Acting Muscarinic Antagonist [LAMA], Short-Acting β2-
Agonists [SABA], Short-Acting Muscarinic Antagonist [SAMA], Inhaled Corticosteroids [ICS], 
LABA and ICS Combination, SABA and SAMA combination, leukotriene modifiers, oral 
phosphodiesterase type 4 [PDE4], systemic corticosteroid, oxygen, methylxanthines, and 
influenza vaccine) and by treatment groups. Prior medication in the reporting by therapeutic 
categories is defined as any medication taken within 15 days prior to Visit 0/1A before initiation 
of a washout period.
All concomitant medications will be classified for each one of the two following periods and 
listed by treatment groups: 1) medications that the patient started to take before the 
randomization and continued after the first IP administration, and 2) medications that the patient 
started to take during the treatment period (from the first IP administration to the last IP 
administration). Medications that were used between the last IP administration and to the study 
end will be summarized for the patients who discontinued IP. In addition, the overall number and 
percentage of patients taking no concomitant medications versus those taking any concomitant 
medications will be summarized for each of these two periods and by treatment group. 
Concomitant medications will be tabulated by the third level of the Anatomical Therapeutic 
Chemical code, preferred name, and treatment group.
The use of prior and concomitant medications will be summarized by the number and percentage 
of patients in each treatment group for the FAS Population. Multiple medication use by a patient 
will only be counted once.

Exposure to double-blind IP for the FAS Population during the double-blind treatment period 
will be summarized for treatment duration, calculated as the number of days from the date of the 
first dose of double-blind IP taken to the date of the last dose taken, inclusive. Descriptive 
statistics (n, mean, standard deviation, minimum, median, and maximum) will be presented by 
treatment group.
9.7.4.2
Measurement of Treatment Compliance
Dosing compliance for the double-blind treatment period is defined as the total number of 
treatment applications (puffs) taken by a patient during that period divided by the number of 
puffs expected to be taken during that same period multiplied by 100.

Descriptive statistics for IP compliance will be presented by treatment group for each 
scheduled visit and overall during the double-blind treatment period for the FAS Population. 
Further information on how to calculate the compliance will be provided in the statistical 
analysis plan (SAP).
9.7.5
Efficacy Analyses
Efficacy analyses will be based on the FAS Population. All statistical tests will be two-sided 
hypothesis tests performed at the 0.05 alpha level of significance for main effects. All 
confidence intervals will be two-sided 95% confidence intervals, unless stated otherwise.
To control for multiplicity, the primary and secondary efficacy variables will be tested 
sequentially, i.e., the secondary efficacy endpoint will be tested only when both primary and 
secondary analyses on the primary efficacy endpoint achieved statistical significance, and the 
secondary analysis on the primary efficacy endpoint will be tested only when the primary 
analyses on the primary efficacy endpoint achieved statistical significance. Otherwise, nominal 
p-values will be provided and should be interpreted descriptively.
9.7.5.1
Primary Efficacy Parameter
The primary efficacy parameter is the following:
!
Rate of moderate or severe COPD exacerbations during the first year of treatment per patient 
per year
The primary efficacy endpoint of rate of moderate or severe COPD exacerbation per patient per 
year during the first year of treatment will be presented for the FAS population. The rate ratio of 
moderate or severe COPD exacerbation per patient per year due to the effect of aclidinium 
bromide 400 μg BID relative to placebo will be estimated along with its confidence interval and 
the corresponding p-value. 
Exacerbation rate in aclidinium group will be compared to exacerbation rate in the placebo group 
using a Negative Binomial regression model. The response variable in the model will be the 
number of moderate or severe COPD exacerbations experienced by a patient during the first year 
of treatment. The model will include treatment group, baseline ICS use, baseline COPD severity, 
history of at least one exacerbation in the past year, and smoking status as factors. In order to 
adjust for the exposure for each patient, the natural logarithm of the exposure time (in years) 
during the first year of treatment will be used as an offset variable. When used as the offset 
variable, the exposure time will be adjusted by subtracting the time when a patient experienced 
COPD exacerbation(s) (i.e., not at risk during an exacerbation). If the Negative Binomial 
regression model does not converge, the Poisson regression model with robust variance estimate 
using sandwich method will be applied.

The primary analysis on the primary efficacy endpoint will be based on on-treatment analysis, 
i.e. for those patients who prematurely discontinue during the first year of double-blind treatment 
period and have follow-up assessments, the primary analysis will be based on the data collected 
before treatment discontinuation. The secondary analysis of this endpoint will be based on on-
study analysis using the same model as for the primary analysis of the primary efficacy endpoint.
For those patients who prematurely discontinue IP during the first year of treatment and have 
follow-up assessments, the secondary analysis will include the events collected during the PTFU
period up to one year.
The rate ratio of moderate or severe COPD exacerbation per patient per year due to the effect of 
aclidinium bromide 400 μg BID relative to placebo will be estimated along with its confidence 
interval and the corresponding p-value. The two-sided p-value for aclidinium bromide 400 μg 
BID relative to placebo in reducing the rate of exacerbation will be compared to the 
0.05 significance level.
Sensitivity analyses 
To assess the robustness to variations of the data assumptions underlying the primary and 
secondary analysis of the primary efficacy endpoint, several sensitivity analyses will be 
conducted as follows:
!
Jump to reference (J2R) approach (see Appendix 1 for details) 
!
Copy reference (CR) approach (Keene et al, 2014; see Appendix 1 for details) 
!
Tipping point analysis (see Appendix 2 for details)
9.7.5.2
Secondary Efficacy Parameter
The secondary efficacy variable is rate of hospitalization due to COPD exacerbation per patient 
per year during the first year of treatment. This will be analysed (on-treatment analysis) using the 
same model as for the analyses of the primary efficacy endpoint, including on-study analysis as 
sensitivity analysis.
9.7.5.3

COPD Exacerbations 
All additional efficacy parameters will be presented based on the FAS population. The details 
will be described in the SAP. 
The rate of COPD exacerbations per patient per year (any, and moderate or severe) will be 
analyzed using a Negative Binomial regression model similar the primary analysis of the primary 
efficacy parameter. For categories that Negative Binomial regression does not converge, the 
Poisson regression model with robust variance estimate using sandwich method will be applied. 
The details will be described in the SAP. The durations of all endpoints of COPD exacerbation
days will also be summarized for only the patients who had exacerbations during the double-blind
treatment period.
The number of patients with at least one COPD exacerbation (any, mild, moderate, severe, and 
moderate or severe) will be analyzed based on a logistic regression model with treatment group
and baseline COPD severity and smoking status as factors.
Time (days) to first COPD exacerbation (any, and moderate or severe) will be analyzed by 
means of Kaplan-Meier estimators and Cox Proportional Hazards model. The estimates of the 
hazard ratio comparing aclidinium bromide 400 μg with placebo will be derived using the Cox 
proportional hazard model for the time in terms of the number of days served as a response and 
treatment group, baseline ICS use, baseline COPD severity, history of at least one exacerbation 
in the past year, and smoking status as factors. 
Duration of COPD exacerbations per patient per year (any, and moderate or severe) will be 
summarized descriptively.

Spirometry
The additional efficacy spirometry parameter, change from baseline in morning pre-dose trough 
FEV1 at visits 2, 3, 4, 5, 6, 8, 10, and 12, will be analyzed using a mixed model for repeated 
measures (MMRM). Treatment group will be fitted as the explanatory variable, and pre and 
post-bronchodilator (albuterol/salbutamol) FEV1 at screening visit (Visit 1A), and baseline FEV1
as covariates, and smoking status, baseline ICS use, visit, and treatment group-by-visit 
interaction as fixed effect factors. The within-patient correlation will be modeled using the 
unstructured covariance matrix. If the model does not converge, then the compound symmetry 
covariance structure will be used.
9.7.6
Safety Analyses
The safety analysis will be performed using the FAS Population. For the safety analysis, the 
safety parameters are AEs including COPD exacerbations, vital sign measurements, ECG 
parameters, and physical examination findings. For each safety parameter, the last assessment 
made before the first dose of double-blind IP will be used as the baseline for all analyses of 
that safety parameter.
9.7.6.1
Primary Safety Parameter
The primary safety parameter is time to first MACE.
The primary safety endpoint of time to first MACE will be presented for the FAS Population and 
will be based on on-study analysis. The on-study analysis will be used as it provides an overall 
evaluation of the effect of aclidinium or placebo, as well as reduces the potential bias caused by 
censoring events and patients as a result of differences in study drug adherence. We are defining 
on-study analysis as all events that occurred while the patients was in the study, irrespective of 
treatment exposure (i.e., this includes all events that occurred while a subject was on treatment or 
off treatment).   
In addition, to account for the relation of the occurrence of an event and treatment exposure, an 
on-treatment analysis will also be conducted and this will include only events that occurred while 
the patient was exposed to study treatment, i.e., events that occurred after the patient’s last 
treatment dose was censored. Two ascertainment windows, 0 and 15 days, will be evaluated in 
the on-treatment analyses. The on-treatment and on-treatment +15 days analyses will censor 
events that occur after and more than 15 days after, respectively, after the last treatment dose. 
While a primary method is pre-specified, patterns and timing of discontinuation from study 
treatment, as we as selected replacement therapy will be carefully evaluated between aclidinium 
bromide 400 μg BID and placebo. The impact of these explorations in the analysis methods (i.e., 
the on-study analysis and on-treatment analysis) will be thoroughly assessed. Since both 
approaches have limitations, the totality of evidence will be carefully weighed regarding the 
evaluation of MACE. 
The choice of on-study and on-treatment analyses (applying different censoring scheme) is 
consistent with the SAVOR-TIMI 53 trial [Scirica et al, 2013, Geiger et al, 2015] and the 
TIOSPIR trial assessing all-cause mortality [FDA Briefing Book for Pulmonary-Allergy Drugs 
Advisory Committee Meeting August 14, 2014 for NDA# 21936].

The primary safety endpoint will be analyzed based on Cox-proportional hazards regression 
model including, baseline CV severity, smoking status, and treatment group as covariates. The 
assumption of proportional hazards will be assessed visually using log-cumulative hazard plots. 
The effect of any departures from proportional hazards will be discussed as part of the 
presentation of results of the analyses. The CV severity at baseline will be defined as 2 
categories: 1) patients who had 2 CV risk factors, and 2) patients who had more than 2 CV risk 
factors or at least one non-fatal stroke or non-fatal MI. This model will provide point estimate for 
the hazards ratio (aclidinium over placebo), as well as corresponding 95% confidence interval. 
The upper bound of the 95% confidence interval (based on Cox regression) for the hazard ratio 
(aclidinium relative to placebo) of time to first MACE will be used to rule out the null hypothesis 
of hazard ratio of 1.8 for the primary test on MACE. If the upper bound of the 95% confidence 
interval is less than the 1.8 margin of the hazard ratio, then the hazard ratio of 1.8 or higher will 
be ruled out (justification for the hazard ratio of 1.8 is provided in Appendix IV). In addition, the 
Kaplan-Meier survival curves will be displayed for each treatment group.
The results from the primary safety analysis will also be evaluated considering a superiority 
hypothesis.
Sensitivity analyses
To account for the relation of the occurrence of an event and treatment exposure, an on-treatment 
analysis will be conducted and this will include only events that occurred while the patient was 
exposed to study treatment, i.e., events that occurred after the patient’s last treatment dose will 
be censored. Two ascertainment windows, 0 and 15 days, will be evaluated in the on-treatment 
analyses. The on-treatment and on-treatment +15 days analyses will censor events that occur 
after and more than 15 days after, respectively, after the last treatment dose.
Sensitivity analysis of the primary composite endpoint will include analysis with CV death 
replaced with all-cause mortality. 
Sensitivity analysis will also be conducted to assess the impact of change in the inclusion 
criteria, by including in the model as factor a flag (1=Pre-/2=Post-) to account for the change 
in the inclusion criteria.
9.7.6.2
Secondary Safety Parameter
The secondary parameter is the following:
!
Time to first MACE or other serious cardiovascular events of interest (ie, SMQ of cardiac 
disorders and SMQ of cerebrovascular disorders)

comparisons.
The secondary safety endpoint of time to first MACE or other serious cardiovascular events of 
interest (ie, SMQ of cardiac disorders and SMQ of cerebrovascular disorders) will be analyzed 
for the FAS Population using the same method as the primary safety endpoint using a confidence 
level of 95% and without statistical testing for non-inferiority (non-inferiority margin will not be 
used). Supportive listings will be provided for all adjudicated events with adjudication 
conclusions.
9.7.6.3
Additional Safety Parameters
a)
Adverse Events
Adverse events will be coded by system organ class and preferred term using the Medical 
Dictionary for Regulatory Activities, Version 15.0 or newer.
An AE (classified by preferred term) will be considered a treatment-emergent adverse event 
(TEAE) if it started on or after the date of the first dose of double-blind IP or it started before the 
date of the first dose of double-blind IP and continued during the double-blind treatment period 
with increased severity. An AE that occurs more than 15 days after the date of the last dose of 
double-blind IP will not be counted as a TEAE.
AEs will be collected only once with its maximum intensity, except when the AE started before 
first IP administration, persisted after it and worsened in intensity any time after first IP. In this 
latter case, the AE will be collected with each respective intensity. The AE term recorded must 
be exactly the same in the different intensities collected.
The number and percentage of patients reporting TEAEs in each treatment group will be 
tabulated by system organ class, high level term, and preferred term; by system organ class, high 
level term, preferred term, and severity; by system organ class, high level term, preferred term, 
and relationship to the IP; and by system organ class, high level term, preferred term, and 
outcome. If more than one AE is coded to the same preferred term for the same patient, the 
patient will be counted only once for that preferred term using the most severe and most related 
occurrence for the summarization by severity and by causal relationship to the IP.
For the summary table by system organ class, high level term and preferred term, the distribution 
of TEAEs in each treatment group will be sorted in decreasing frequency by preferred term for 
aclidinium bromide 400 μg within each system organ class.
The incidence of common (e.g. ≥ 2% of patients in any treatment group) TEAEs will be 
summarized by preferred term.
All the incidences will be sorted by decreasing frequency for aclidinium bromide 400 μg.

A SAE that occurs on or after the date of the first dose of double-blind IP and within 15 days of 
the date of the last dose of double-blind IP will be considered an on-therapy SAE. The number of 
percentages of patients with on-therapy SAEs, and AEs leading to premature discontinuation of 
the IP will be summarized by by SOC and PT, and treatment group and will be sorted by 
decreasing frequency for aclidinium bromide 400 μg. In addition, the incidence of fatal on-
therapy SAEs (i.e. events that caused death) will be summarized separately by preferred term, 
and treatment group.
For the Screened Population, separate listings will be presented for patients with SAEs, patients 
with AEs leading to discontinuation, and patients who die (if any).
b)
Vital Signs
Descriptive statistics for vital signs (pulse rate, sitting systolic and diastolic BP) and changes 
from baseline values at each visit and at end of study will be presented by treatment group.
Vital sign values will be PCS if they meet both the observed-value criteria and the change from 
baseline–value criteria. The criteria for PCS vital sign values will be detailed in the SAP. The 
percentages will be calculated relative to the number of patients with baseline values and at least 
one postbaseline assessment. The numerator will be the total number of patients with available 
baseline values and at least one PCS postbaseline value in the treatment period. The denominator 
will be the total number of patients with available non-PCS baseline values and at least one 
postbaseline assessment. A supportive listing of patients with PCS postbaseline values will be 
provided, including the PID number, study center number, and baseline and postbaseline values. 
A listing of all AEs occurring in patients who have PCS vital sign values will also be provided.
c)
Electrocardiogram
Descriptive statistics for ECG parameters (i.e. ventricular heart rate, RR interval, PR interval, 
QRS interval, QT interval, and QTc interval) and changes from baseline values at each 
assessment time point will be presented by treatment group. The QTc interval is calculated using 
both the Bazett (QTcB = QT/(RR)½) and Fridericia (QTcF = QT/(RR)⅓) corrections.
The number and percentage of patients with PCS postbaseline ECG values will be tabulated by 
treatment group. The criteria for PCS ECG values will be detailed in the SAP. The percentages 
will be calculated relative to the number of patients with available non-PCS baseline values and 
at least one postbaseline assessment. The numerator will be the total number of patients with 
available baseline values and at least one PCS postbaseline value in the treatment period. A 
supportive listing of patients with PCS postbaseline values will be provided, including the PID 
number, study center number, and baseline and postbaseline values. A listing of all AEs for 
patients with PCS ECG values will also be provided.

i) Physical Examination
A listing of physical examination findings at Screening (Visit 1A) will be provided by treatment 
group as a part of the medical history listing. Any new physical examination finding or change 
(worsening) since the previous physical examination will be recorded as an AE in the appropriate 
AE eCRF form. If any clinically significant change is observed after randomization (Visit 2), it 
should be recorded in the AE eCRF form.
ii) All-cause mortality
All-cause mortality based on patient’s vital status data will be analyzed using the same method 
as the primary safety endpoint using a 95% CI and without statistical testing for NI (NI margin 
will not be used).

Health Economics and Outcomes Research Analyses
CAT by Visits
The change from baseline of CAT score will be analyzed with MMRM models. The model may 
adjust for baseline CAT and history of at least one exacerbation in the past year as covariates, 
and treatment group, sex, smoking-status, visit, and treatment group-by-visit interaction as fixed 
effect factors. 
Descriptive statistics will also be provided.
In addition, changes from baseline in the CAT score will be evaluated in a responder analysis.
Further details for CAT calculation and analysis will be given in the SAP.

Interim Analysis
No interim analysis is planned for this study.
9.7.9
Determination of Sample Size
9.7.9.1
Power for the Primary Safety Endpoint: Time to First MACE Event
For this study, a total of 122 patients with MACE will be needed to have 90% power, at 5% 
significance level, to rule out a hazard ratio of 1.8 in time to first MACE in aclidinium bromide 
treated patients relative to placebo, assuming the hazard rate is 1.0 under the alternative 
hypothesis.  The justification for the hazard ratio of margin of 1.8 is provided in Appendix IV.
The study will be stopped when a total of 122 patients with MACE are observed.
The COPD safety database for the new drug application of roflumilast filing included a total of 
3,310 patient-years on roflumilast 500 μg and 3,448 patient-years on placebo. That is a total of 
6,758 patient years. Based on this exposure a total of 126 MACE were observed leading to ~1.9 
MACE per 100 patient years (out of the 126 MACE only 1 patient had 2 MACE). Also the 
majority of the patients in this program were recruited based on % predicted FEV1 below 50%.

Amended Protocol LAS-MD-45 Amendment 5

Final
30 Aug 2017
The placebo group in the UPLIFT study had 2.89 MACE per 100 patient-years while tiotropium 
group had 2.25 MACE. It should be noted that this was a 4-year study and therefore it is possible 
more events occurred in the last 2 years of treatment than in the first two years as the health 
status of the patients could be worse over time (Boehringer Ingelheim, 2009).
This ASCENT COPD study will be recruiting patients with an FEV1 below 80% and a planned 
maximum of 3 years double-blind treatment period.  The assumption of 1.9 MACE per 100 
patient years would be reasonable for this study. To obtain 122 MACE in this study with 1.9 
MACE per 100 patient years of treatment, a total of 6,500 patient years of treatment (aclidinium 
and placebo) would be needed. 
Assuming a treatment discontinuation rate of 40% and a study discontinuation rate of 20% at 
year 2, and following an exponential distributions for time to events and time to discontinuations, 
a sample size of 4000 is needed to ensure 90% power to observe 122 events applying the on-
study analysis, and an 80% power to observe 91 events applying the on-treatment analysis.
9.7.9.2
Power for the Primary Efficacy Endpoint: Rate of Moderate or Severe 
Exacerbations Per Patient Per Year During First Year of Treatment
The sample size of 4,000 patients after 1 year of treatment will have ~89% power to detect a 
reduction in the rate of moderate or severe COPD exacerbations per patient per year during the 
first year of treatment of 14% (rate ratio of 0.86 in aclidinium bromide relative to placebo) at 
0.05 alpha level (Table 9.7.9–1.). The 89% power was calculated assuming a discontinuation rate 
of 30% during the first year, a placebo rate of 0.8 exacerbation per patient per year (reduced 
from 1 to 0.8 as not all patients will have a history of exacerbation prior to randomization), and 
an over-dispersion factor k of 0.67 [Keene et al, 2007]. 
The clinical significance in reduction in the rate of exacerbation is not clearly defined for 
powering studies. Roflumilast was approved based on average reduction in exacerbation rate per 
patient per year of 17% relative to placebo averaged across the two pivotal studies. Tiotropium in 
the Handihaler® was approved for exacerbation based on UPLIFT trial along with another 6 
months trial. The hazard ratio for time to first moderate or severe COPD exacerbation in UPLIFT 
was 0.86 (tiotropium relative to placebo) and the rate ratio per patient per year in moderate or 
severe COPD exacerbation was 0.86, implying a reduction of 14% (Boehringer Ingelheim, 
2009).

PULMONARY FUNCTION TESTS
The Investigative site should have the spirometers and all necessary equipment (computer, 
calibration syringe, printer, paper, ink, etc.), and the proper training from American Association 
for Respiratory Care (AARC) (for qualification of all technicians in charge of conducting 
spirometry) is needed in order to conduct this clinical trial per the protocol requirements. 
Spirometers will measure FVC (maximal volume of air exhaled with maximally forced 
expiratory effort from a position of maximal inspiration) and FEV1 (volume of air expressed in 
liters exhaled during the first second of performance of the FVC) and will meet American 
Thoracic Society and European Respiratory Society recommendations for accuracy and precision 
(Miller et al, 2005).
Spirometer recommendations for the study provided devices should be followed to provide 
accurate and comparable spirometric data, and calibration should be performed every day the 
system is used. Daily calibration on the day of testing procedures should be conducted with a 3-
liter syringe which will allow validation of spirometer accuracy (GOLD, 2017. Spirometry must 
be performed at temperatures between 17°C and 40°C. Efforts should be made to perform all 
maneuvers at approximately the same temperature. A notebook must be maintained to document 
daily (at least for those days spirometric procedures have to be done) ambient temperature. In 
case of significant changes in temperature and/or barometric pressure within the same day, 
calibration must be repeated before any other spirometry is done. Daily equipment calibration for 
days where testing is conducted as well as appropriate staff training records should be kept in the 
site’s regulatory notebook.
Before the first spirometry is conducted for this clinical trial, the trained operator may 
demonstrate the procedure using a detached mouthpiece and then allow two practice attempts. A 
copy of the spirometry tracings should be printed and kept in the patient’s medical records as 
source documentation.
The technician performing the test must properly wash his/her hands or use gloves to avoid any 
possible contamination. Reusable mouthpieces, breathing tubes, valves, and manifolds should be 
properly disinfected or sterilized regularly in accordance to the recommendations of the 
American Thoracic Society and European Respiratory Society ATS/ERS (Miller et al, 2005).
Spirometry Maneuvers
Pulmonary function tests will be performed by highly experienced personnel. At each time point, 
3 technically adequate measurements should be performed according to the acceptability and 
repeatability criteria of the American Thoracic Society and European Respiratory Society 
ATS/ERS (Miller et al, 2005).
Patients should be able to produce repeatable pulmonary function testing (ie, the two best 
acceptable spirometry efforts must have FEV1 and FVC values that do not vary by more than 150 
mL). If both the acceptability and repeatability criteria are met, the test session may be 
concluded. If both of these criteria are not met, additional maneuvers should be performed until 
both criteria are met OR a total of 8 tests have been performed, unless the patient cannot 
continue. All maneuvers completed, whether deemed acceptable or not, must be retained and 
provided as source documentation.

The data for each visit must be entered into the electronic data capture system, including patient 
ID, date, time, visit number, whether spirometry was performed, whether the patient had a
bronchodilator in the previous 6 hours, and the reason for visit, if it was unscheduled. The 
spirometry assessment results should be printed, signed by the technician and PI, and kept in the 
patient’s medical record as source documentation.
Throughout the study, the reading of spirometric values is to be performed by the PI, or 
appropriately trained designee, to ensure the values meet the American Thoracic Society and 
European Respiratory Society criteria for acceptability. At each time point, only the greatest 
acceptable FEV1 and FVC value will be used for all analyses.
The circumstances of the test should be similar on all occasions with respect to time of the day, 
temperature and pressure as well as the technician. Smoking and prolonged exposure to cold air, 
dust, and polluted air should be avoided for at least 1 hour before each visit until the completion 
of all study procedures. For patients having difficulty not smoking, nicotine gums or patches may 
be used.
Patients should be at rest for 15 minutes before the test and comfortable; tight or cumbersome 
clothing should be loosened to allow the thorax to move freely. Measurements are to be made 
with the patient seated in an upright posture and wearing a nose clip.
The procedure should be carefully described to the patient, with an emphasis on the need to 
avoid leaks around the mouthpiece. The following order of the spirometric maneuvers must
be followed for forced maneuvers for measuring FEV1 and FVC:
!
Breathe in as deeply and quickly as possible.
!
Immediately place the mouthpiece in your mouth and seal your lips tightly around it.
!
Blow out as hard and as fast as you can, remaining upright and keeping your lips sealed.
!
When your lungs are empty, remove the mouthpiece and breathe in normally.
At the time of forced maneuver, the technician performing the measurement should prompt the 
patient to blast, not just blow, the air from the lungs; continue to encourage him/her to fully 
exhale. Throughout all complete maneuvers, the technician should enthusiastically coach the 
patient by word and body language and attempt to obtain 3 acceptable and repeatable efforts with 
a maximum of 8 attempts for each assessment. The technician should provide the patient with 
ample time for the patient to rest between each maneuver.
Any bronchoconstriction that appears after consecutive measurements should be noted on the 
eCRF as an AE.

POWER COMPUTATION DETAILS
ASSESSMENT OF BENEFIT-RISK RATIO AND JUSTIFICATION OF ACCEPTABLE 
INFERIORITY MARGIN OF HAZARD RATIO
A selected hazard ratio of 1.8 for time to first MACE for aclidinium relative to placebo that 
would need to be ruled out statistically is the subject of this appendix. The justification will be 
based on the NNH with 1 MACE per year of treatment compared to Number Needed to Treat 
(NNT) to reduce 1 exacerbation per patient per year and more importantly compared to NNT to 
reduce 1 hospitalization due to COPD exacerbation per patient per year. In COPD patients, the 
event of hospitalization due to COPD exacerbation may be considered comparable to a MACE. 
As can be seen from Table 13–1 and  Table 13–2 below, aclidinium 400 μg BID showed a 
reduction in the rate of moderate or severe COPD exacerbations of 26.4% across the three Phase 
III studies (3 to 6 months treatment period in these 3 studies). Also, the effect of aclidinium 400 
μg BID on hospitalization due to COPD exacerbation was also strong as can be seen in Table 
13–1. Approximately 12% of the moderate or severe exacerbations led to hospitalization. These 
data are being used to generate the exacerbation hypotheses proposed for this study and to 
estimate the benefit from aclidinium treatment in terms of reducing both COPD exacerbations 
and hospitalizations. In addition, the UPLIFT study showed that: tiotropium reduced the rate of 
moderate or severe COPD exacerbations by 14% over 4 years period; 27% of patients in the 
placebo group were hospitalized due to COPD exacerbation versus 25.4% of patients in the 
tiotropium group; the UPLIFT study showed that exacerbations are the largest cause of death in 
the population of COPD patients (Boehringer Ingelheim, 2009) (see Table 13–3).

Approach of Benefit Assessment: Expected NNT with Aclidinium to Reduce 1 
Exacerbation or Hospitalization
For the purpose of assessing the benefit of reduction in exacerbation or hospitalization per year
we assume the placebo group to have a rate of 0.8 event per patient per year and the aclidinium 
group to have a rate of ~0.69 per patient per year (a reduction of 14%). Based on these 
assumptions, the aclidinium benefit can be measured by 9 NNT for 1 year to reduce 1 moderate 
or severe COPD exacerbations, calculated as 1/(1 - 0.89). The NNT to reduce 1 hospitalization 
due to COPD exacerbation can be predicted to be 42 (this calculation is based on the assumption 
of 12% of the moderate or severe exacerbation would be hospitalized as observed in Table 13–1, 
a rate of 0.12 per patient per year for placebo and 0.096 for aclidinium - a reduction of 20%).

It is understood that the reduction in exacerbation of 14% is not known at this point in the 
planned population. However, since the hypothesis of hazard ratio margin for risk of MACE 
depends on the benefit magnitude of aclidinium we assume a reasonable expected benefit for the 
patients from aclidinium treatment for their COPD exacerbation and then compare that to the risk 
of MACE.
Approach of Risk Assessment: NNH with 1 MACE Per Year
This NNH with 1 MACE per year method for assessment of risk is an alternative approach to the 
hazard ratio. This is equivalent and easier to compare the benefit based on NNT to reduce 1 
exacerbation or hospitalization. The statistical test based on the upper bound of the confidence 
interval for the hazard ratio being lower than a null hazard ratio margin is the same as using a 
test based on the lower bound of the confidence interval for the NNH being greater than a null 
NNH margin. A lower NNH indicates that a product is associated with higher risk to the patient. 
Conversely, a higher NNH indicates a lower risk to the patient. Likewise a low margin of NNH 
corresponds to a high hazard ratio margin. These arguments are used to generate the margins for 
NNH that corresponds to the hazard ratio margins of 1.5, 1.7, 1.8, and 2.0 (See Table 13–4 below 
for details).
Table 13–4 provides NNT to reduce 1 exacerbation and the margin for NNH with 1 MACE that 
corresponds to the HR margin of 1.8 along with other useful information. Other important 
information from Table 13–4 is the maximum point estimate of the hazard ratio that can be 
observed to rule out the hazard ratio margin of 1.8, which is 1.262. The corresponding minimum 
point estimate of NNH to rule out the null NNH margin of 66 (with one MACE) is 201 patients 
per year. (See Table 13–4 for detailed calculations).
In the previously submitted study design, it was proposed to rule out a hazard ratio of 1.5. During 
the discussion at the aclidinium PADAC, the advisory board was asked to provide the Sponsor 
with advice on this preliminary study design. Two clear messages emerged:
!
The study results should be available as soon as possible, and the study design should be 
adjusted to allow for this
!
In evaluating the risk of MACE, the Sponsor should consider the potential benefit of 
reduction in exacerbations in addition to assessing risk of MACE, and we should consider 
adjusting the hazard ratio accordingly. Dr. Mauger pointed out a hazard ratio margin higher 
than 1.5 could be justified based on the NNH with 1 MACE.
He argued that for such an extremely rare event, you can have a hazard ratio of 1.5 and still be 
looking at a NNH of over 100, which may lead to accepting the null hypothesis in which the 
hazard ratio is set too low to be clinically meaningful. A complete discussion by Dr. Mauger and 
the chair of the PADAC regarding the HR margin is provided in Appendix 12.2. The NNH 
approach in this document (see Table 13–4) along with benefit-risk assessment was used to 
justify a HR margin of 1.8. 

Amended Protocol LAS-MD-45 Amendment 5

The calculations of risk are based on assuming 1.9 MACE per 100 patient years in the placebo 
group. A value of 201 for minimum point estimate of NNT in column 2 can be obtained as the 
minimum integer higher than 1 over ((1.262 × 0.019) – 0.019). This calculation assumes the 
hazard ratio is the same as the rate ratio and this is a valid assumption for low rates as 0.019.
It should be noted that the null hypothesis based on the hazard ratio margin of at least 1.8 is the 
same as the null hypothesis of at most 66 NNH margin with 1 MACE per year. Therefore, ruling 
out a hazard ratio of 1.8 or higher is the same as ruling out an NNH of 66 or lower.
The null NNH margin of 105 is calculated as 1/(0.0285 – 0.019) where the 0.019 is the assumed 
placebo mean rate of MACE per 1 patient per year which is the same as 1.9 events per 100 
patient years and the 0.0285 is the mean rate of MACE per 1 patient per year in the aclidinium 
group calculated under the null (the hazard ratio margin of 1.5 = 0.0285/0.019).
Benefit-Risk Ratio: Justification of Using 1.8 Hazard Ratio
The potential risk of treatment with aclidinium will be assessed in the context of the potential 
benefit to the patient through reduction of exacerbations and COPD-related hospitalizations. The 
NNH will define the risk of having a MACE, while the NNT will establish the potential benefit 
of avoiding an exacerbation or COPD-related hospitalization. This approach is consistent with 
the advice the Sponsor and the Agency were given at the PADAC. The established benefit of 
FEV1 bronchodilator effect of aclidinium bromide in the Pressair® DPI with supporting 
pulmonary function (ie, FVC, IC), SGRQ and other symptom data provide additional evidence in 
support of the reduction of exacerbations.
NNT: Reduction in Exacerbations and COPD-related Hospitalizations
The benefit from aclidinium treatment is predicted to be an NNT of 9 patients per year to reduce 
1 moderate to severe COPD exacerbation. Also, it can be seen above as an NNT of 42 patients 
would be expected to eliminate 1 hospitalization per year (Table 13–1 and Table 13–2).
NNH: MACE
The NNH for 1 MACE that will be compared to the above NNT to benefit in reducing 
1 exacerbation is the minimum point estimate of NNH of 201 patients with 1 MACE per year of 
treatment to rule out the null margin of 1.8 for the hazard ratio (or corresponding NNH of 66). 
The NNH of 201 for 1 MACE is the lowest number of patients needed to reject the null 
hypothesis (NNH margin of 66 or HR = 1.8 margin). In those 201 aclidinium treated patients, the 
benefit can be explained by the expected reduction of 22.3 events (201/9) of moderate or severe 
exacerbations and of those 22.3 events, 4.8 are expected to be COPD hospitalizations (201/42). 
Therefore, for each reduction of 4.8 hospitalizations due to COPD exacerbations at most 1 
additional MACE is allowed for the success of the study based on MACE.
It should be noted in addition to the assumed reduction in exacerbation/hospitalizations benefit, 
aclidinium has demonstrated robust efficacy as a bronchdilator in COPD, improvement in 
SGRQ, reduction in the use of rescue medication, and improvement in dyspnea. These benefits 
justify the selection of the hazard ratio margin of 1.8 for the null hypothesis of time to first 
MACE for aclidinium relative to placebo that needs to be ruled out statistically.

Rationale for Change in Hazard Ratio Margin From Preliminary Study Synopsis
From Table 13–4, the NNH of 303 patients with 1 MACE is the most extreme point estimate of 
MACE risk for the study to be successful in ruling out the 1.5 margin of the hazard ratio (this 
corresponds to a null margin in NNH with 1 MACE of 105 patients). In this 303 aclidinium 
treated patients, the harm of 1 MACE is best compared to the expected reduction of 33.7 events 
(303/9) of moderate or severe exacerbations and of those 33.7 events 7.2 are expected to be 
COPD hospitalizations (303/42).
Based on the null margin of a hazard ratio of 1.5, the study is designed to be too strict with 
respect to the MACE margin of 1.5 for hazard ratio. The boundary for success is that for harm 
with 1 additional MACE and a benefit in the reduction of 34 exacerbations (7 of which are 
expected to be COPD hospitalizations) is required. It would not be appropriate to consider the 
study a failure if an increase beyond 1 MACE (such as 1.1) is observed despite the expected 
benefit in the reduction of 34 COPD exacerbations (7 of which are expected to be COPD 
hospitalizations.)

†
Point estimate of NNT for 1 year to reduce 1 COPD exacerbation was calculated assuming 14% reduction in the rate of 
exacerbation per patient per year from an average rate of 0.8 event per patient per year in the placebo group.
‡
Minimum point estimate of NNH with 1 MACE to rule out the null margin was calculated by assuming 1.9 MACE per 100 
patient years in the placebo group and by using the maximum point estimate of HR to rule out the null margin of HR. For 
example the 303 value of minimum point estimate of NNT in column 2 can be obtained as the minimum integer higher than 
1 over ((1.174 x 0.019) - 0.019). This calculation assumes the hazard ratio is the same as the rate ratio and this is a valid 
assumption for low rates as 0.019.
It should be noted that the null hypothesis based on the hazard ratio corresponds to the null hypothesis based on NNH with 
1 MACE (For example the null hypothesis based on the hazard ratio of at least 1.8 is the same as the null hypothesis of at 
most 66 NNT with aclidinium to harm with 1 MACE. Therefore, ruling out a hazard ratio of 1.8 or higher is the same as 
ruling out an NNH of 66 or lower.)
# The NNH margin of 105 is calculated as 1/(0.0285 - 0.019) where the 0.019 is the assumed placebo mean rate of MACE per 1 
patient per year which is the same as 1.9 events per 100 patient years and the 0.0285 is the mean rate of MACE per 1 
patient per year in the aclidinium group calculated under the null (the hazard ration of 1.5 = 0.0285/0.019).
