Objectives:
The primary objective of the study is to evaluate the effect of   
tiotropium + olodaterol FDC compared to tiotropium monotherapy on 
the intensity of breathlessness during the 3min CSST.
A secondary objective is to explore the relationship between reductions 
in breathlessness during the 3min CSST and reductions in 
breathlessness during activities of everyday living as measured by the 
dyspnea domain of the Chronic Respiratory Questionnaire (CRQ)
following bronchodilator therapy. 
Methodology:
Randomised, double-blind, active-controlled, cross-over design 
comparing two treatments after 6 weeks of treatment.

Statistical methods:
Restricted Maximum Likelihood Estimation based Mixed-effects Model 
for Repeated Measures (MMRM) analysis will be used to obtain 
adjusted means for the treatment effects.
This model will include treatment and period as fixed effects, patient as 
a random effect and period baseline as well as patient baseline as 
covariates. The patient baseline will be obtained by calculating the 
mean of period baselines for each patient. Compound symmetry will be 
used as a covariance structure for within patient variation. 
Descriptive statistics for the safety analyses.

INTRODUCTION
MEDICAL BACKGROUND
1.1
European Respiratory Society (ERS), American Thoracic Society (ATS) and Global Initiative for 
Chronic Obstructive Lung Disease (GOLD) treatment guidelines all place bronchodilators as the 
foundation of pharmacologic management of COPD. In patients with moderate to very severe 
pulmonary impairment (i.e., GOLD Stage 2 to 4) whose symptoms are not adequately controlled 
with as-needed short-acting bronchodilators, adding regular treatment with one or more long-
acting inhaled bronchodilators is recommended (long acting β2-agonists, LABAs; long acting 
muscarinic antagonists, LAMAs). 
The rationale for combining bronchodilators with different mechanisms is based on the notion of 
additive relaxation of airway smooth muscle by direct inhibition of cholinergic activity and 
functional antagonism of bronchoconstriction through β2-adrenergic pathways, with the 
expectation of an increase in the degree of bronchodilation for equivalent or lesser side effects. 
When beta-agonists and muscarinic antagonists with similar or equivalent posologies are 
combined, the opportunity exists for offering a simpler and more convenient administration 
regimen with the development of fixed combinations within the same inhaler device. The 
recently completed clinical development program for tiotropium + olodaterol fixed dose 
combination (FDC) was based on the hypothesis that the combination of the LAMA, tiotropium, 
and the LABA, olodaterol, inhaled once daily, is superior in improving airflow over 24 hours 
compared with tiotropium monotherapy once daily and olodaterol monotherapy once daily.
DRUG PROFILE
1.2
Tiotropium
Tiotropium is an established once-daily (QD) LAMA that improves the main functional and 
patient-orientated outcomes of COPD [P08-12524, P10-08261, P13-04267, P11-07562, P11-
03885, P13-11053].  Tiotropium has also been demonstrated to moderate disease progression, 
even in the early stages of COPD (e.g. patients not receiving maintenance therapy [P10-02376]
or those with GOLD [P14-01052] 2 disease [P09-11278]).
Tiotropium in the dry powder inhaler HandiHaler® has been approved in more than 100 countries 
worldwide. An alternative aqueous formulation for use in the Respimat® inhaler (tiotropium 5μg 
QD) is approved in more than 80 countries worldwide including European Union (EU), Japan, 
United States (US) and Canada. Further information about tiotropium can be found in the 
respective prescribing information for the product.

Tiotropium + olodaterol combination
Tiotropium + olodaterol FDC is an aqueous solution of tiotropium and olodaterol contained in a 
cartridge. It is administered by using the Respimat® inhaler. The same device is used for 
tiotropium (Spiriva® Respimat®). One cartridge is used per inhaler, which is inserted into the 
device prior to first use. 
In the pivotal studies (1237.5/.6) [c01735218-03/c01735249-03] tiotropium + olodaterol FDC 
showed statistically significant improvements in Forced Expiratory Volume in one second
(FEV1) Area Under the Curve (AUC0-3h) response and trough FEV1 response after 24 weeks 
compared to the mono-components and these improvements were maintained up to 52 weeks.
Tiotropium + olodaterol FDC showed statistically significant improvements in health-related 
quality of life [St. George's Respiratory Questionnaire (SGRQ)] and dyspnea experienced during 
everyday activities [Transitional Dyspnea Index (TDI)] after 24 weeks compared to the mono-
components. More patients treated with the combination had an improvement in SGRQ total 
score and TDI focal score greater than the Minimal Clinically Important Difference (MCID).
Treatment with tiotropium + olodaterol FDC also resulted in reductions in both daytime and 
night time rescue bronchodilator use compared to the mono-components.
Tiotropium + olodaterol FDC was shown to be safe and well tolerated over 1 year in a moderate 
to very severe COPD population. The overall incidences of adverse events (AEs), serious 
adverse event (SAEs), fatal AEs, frequencies for cardiac events and Major Adverse 
Cardiovascular Event (MACE) in the tiotropium + olodaterol FDC treatment group were similar 
to the mono-components. The nature and frequency of AEs in general was consistent with the 
disease under study. There were no results in the clinical development program suggesting the 
need for absolute contraindications for the combination product.
For a more detailed description of the drug profile, please refer to the current Investigator’s 
Brochure (IB) which is included in the Investigator Site File (ISF).

RATIONALE, OBJECTIVES, AND BENEFIT - RISK 
ASSESSMENT
RATIONALE FOR PERFORMING THE TRIAL
2.1
Breathlessness upon exertion is the most troublesome symptom reported by COPD patients. 
Furthermore, reduced breathlessness during exercise as a result of reductions in lung 
hyperinflation is believed to be the primary mechanistic explanation for increases in exercise 
endurance time in patients with COPD following treatment with bronchodilators. 
Previous studies have shown significant reductions in lung hyperinflation (increases in 
Inspiratory Capacity (IC)) for tiotropium + olodaterol FDC compared with placebo, tiotropium 
and olodaterol.  However, while the improvement in IC with tiotropium + olodaterol FDC 
compared with placebo was associated with a reduction in breathlessness and an increase in 
symptom-limited endurance time, this was not the case for the increases in IC for tiotropium +
olodaterol FDC compared with the monocomponents [c02094185-02 , c02094318-02 , 
c01735246-02]. Contrasting findings have been observed in the pivotal TONADOTM studies
[c01735218-03 , c01735249-03 ], with significant increases in the Mahler TDI focal score for 
tiotropium + olodaterol FDC compared with tiotropium and olodaterol, providing evidence of 
incremental benefit in activity-related breathlessness for the combination over the 
monotherapies. Therefore, there is a need to better understand the relationship between 
improvements in lung function and activity-related breathlessness for tiotropium + olodaterol 
FDC compared to the monocomponents. 
Traditional constant work rate exercise tests (e.g. endurance shuttle walking, constant work rate 
cycle ergometry) are conducted to the point of symptom limitation, which presents challenges 
regarding the evaluation of symptoms during exercise due to the open-ended nature of these 
tests. To address this issue, a novel exercise methodology, the 3min CSST, has been developed
that allows specific focus on the assessment of activity-related breathlessness (using the MBS-S) 
at specific pre-defined timepoints in patients with COPD. The feasibility and reproducibility of 
the 3min CSST in providing a standardized physical stimulus and a measurable level of 
breathlessness in patients with moderate to severe COPD has been reported [R15-4319]. In one 
study, the responsiveness of the 3min CSST to bronchodilation was confirmed, with a 
statistically significant reduction in the intensity of breathlessness with ipratropium bromide 
compared to placebo [P12-12739].
Breathlessness or dyspnea1 is characterised as “a subjective experience of breathing discomfort 
that consists of qualitatively distinct sensations that vary in intensity [and] vary in their 
                                                
1 In this protocol, the terms “breathlessness” and “dyspnea” are used interchangeably as the general term to describe the subjective experience of 
breathing discomfort [R15-4208 ]; the specific sensation that patients will be asked to attend to during the 3 min CSST is “breathing discomfort” 
(see Appendix 10.5).  In the ATS statement on dyspnea, keywords are identified as “breathlessness”, “shortness of breath” and “respiratory 
sensation”.

unpleasantness and in their emotional and behavioral significance” [1]. There is increasing 
recognition that dyspnea is a multidimensional experience [R15-4209, R15-4207, R15-4211] and 
that, while unidimensional scales can capture the overall severity of dyspnea at a particular time-
point (current or recalled), they do not capture information about the quality of breathing 
discomfort, its unpleasantness or the associated emotional responses. The recent development of 
a conceptual model for dyspnea (figure 1; [R15-4211]) suggests that clinical trials that 
specifically focus on exertional breathlessness should not limit the evaluation solely to the 
intensity dimension, but should conduct a comprehensive assessment that also attends to the 
sensory quality (SQ) and emotional impact of dyspnea in patients with COPD.

TRIAL OBJECTIVES
2.2
The primary objective of the study is to evaluate the effect of tiotropium + olodaterol FDC 
compared to tiotropium monotherapy on the intensity of breathlessness during the 3min CSST.

A secondary objective is to explore the relationship between reductions in breathlessness during 
the 3min CSST and reductions in breathlessness during activities of everyday living as measured 
by the dyspnea domain of the Chronic Respiratory Questionnaire (CRQ) following 
bronchodilator therapy. 
BENEFIT - RISK ASSESSMENT
2.3
The clinical trials conducted to date have shown tiotropium + olodaterol 5/5 μg to be a safe, well 
tolerated and efficacious combination therapy according to treatment guidelines in a moderate to 
very severe COPD patient population that included patients with concomitant cardiovascular
diseases.
The observed incremental bronchodilator response for tiotropium + olodaterol 5/5 μg compared 
to the individual components translated into benefits that were meaningful to the patient, with
improvements in several patient centred outcomes. As such, tiotropium + olodaterol 5/5 μg will 
be a valuable additional therapeutic option for patients with COPD, offering increased treatment
benefit compared to the monotherapies with a comparable safety profile.
Based on the overall assessment of benefit to risk, the application for marketing authorization for 
tiotropium + olodaterol FDC was submitted in the EU and the US in May 2014, and then 
subsequently in several other countries, including Canada. At the time of the final protocol for 
1237.28, marketing authorization has been granted in Belgium, Canada, Germany, Netherlands, 
as well as the US and several other countries.
Potential risks associated with exercise testing will be avoided by implementing standard 
monitoring procedures under appropriate supervision [R13-2820, R13-4694].  
The trial design requires that all eligible patients complete a 3 to 4 week screening period in 
which LABAs and LAMAs are withdrawn prior to randomisation. At the investigator´s 
discretion, ipratropium may be provided to patients who are required to wash out LAMA during 
the washout period prior to randomisation and during the washout period prior to visit 7; 
Boehringer Ingelheim (BI) will provide open-label salbutamol (albuterol) as needed (PRN)
rescue medication for all patients who have signed Informed Consent.
All patients will receive active treatment with either tiotropium + olodaterol FDC (5 µg / 5 µg) 
or tiotropium (5 µg) inhalation solution (control group) during the treatment periods. There is no 
placebo comparator in this trial.
Patients receiving inhaled corticosteroids (ICS) before enrolment will continue their treatment 
(or the ICS component alone if taken as a fixed combination with bronchodilator) at the same or 
equivalent dose and regimen during the study. The only medications that are excluded during the 
treatment period are anticholinergic and long-acting β-adrenergic other than the study drugs.

The proposed medication restriction scheme is considered ethically acceptable given the 
availability of ipratropium metered dose inhaler (MDI) during the wash-out periods, salbutamol 
(albuterol) as rescue medication and permitted use of ICS during the treatment period.  
Safety will be monitored (as described in section 5.2) at site visits and withdrawal criteria are 
provided for investigators’ consideration (as listed in section 3.3.4.1).
According to the prescribing information for Spiolto® (Stiolto® in US, Inspiolto® in Canada), as 
a precautionary measure, it is preferable to avoid the use of Spiolto® during pregnancy. Women 
of childbearing potential may be included in clinical trials for tiotropium + olodaterol (5/5 μg) 
FDC provided appropriate precautions are taken to minimize the risk of pregnancy. These 
precautions include pregnancy testing and use of a highly effective method of birth control.  
Continued testing and monitoring during the trial should be sufficient to ensure compliance with 
the measures not to become pregnant during the period of drug exposure (which may exceed the 
length of study until the follow-up visit at 21 days after discontinuation of study medication) 
[R05-0370].

DESCRIPTION OF DESIGN AND TRIAL POPULATION
OVERALL TRIAL DESIGN AND PLAN
3.1
This is a multi-centre, multi-national, randomised, double-blind, active-controlled, two-period
cross-over, Phase IV study to evaluate the effects of once daily administration of orally inhaled 
tiotropium + olodaterol FDC (5 / 5 μg) (delivered by the Respimat® Inhaler) compared with  
tiotropium  (5 µg) (delivered by the Respimat® Inhaler) on the intensity of breathlessness in
patients with Chronic Obstructive Pulmonary Disease (COPD). 
The trial consists of a run-in period, two 6-week treatment periods, each separated by a 3-week 
wash-out period and a follow-up period.
Figure 3.1:1. Overview of the trial design
After signing Informed Consent and completing an initial screening visit (visit 1), patients will 
enter a 3 to 4-week run-in period to ensure clinical stability (i.e. no exacerbations).  During this 
screening period, they will conduct an Incremental Shuttle Walk Test (ISWT) at visit 1, up to 
three x 3min CSSTs to establish the shuttle test speed at visit 2 and a practice 3min CSST at visit 
3.

Patients who meet all the inclusion criteria and none of the exclusion criteria will be randomised 
at visit 4 into the first of 2 x 6-week double-blind, cross-over treatment portion of the study, in 
which they will receive one of two treatment sequences with the treatment codes as follows: 
A. tiotropium + olodaterol ( 5 / 5  μg) FDC inhalation solution, delivered once daily via the 
Respimat®
B. tiotropium (5  μg) inhalation solution, delivered once daily via the Respimat®
The randomised treatment sequences are AB and BA. An interactive voice/web response system 
named Interactive Response Technology (IRT) will be used for randomisation to a treatment 
sequence in this trial and for appropriate re-supply of medication to patients.
IRT will also be set-up to ensure that the number of GOLD Stage II patients is capped at 
approximately 50% and the number of GOLD Stage III patients is capped at approximately 50%.  
This will allow a better representation of the different stages of pulmonary impairment in the 
trial.
The patient’s GOLD stage will be entered in IRT at the screening call that should take place at 
visit 1.  The following classification of severity of airflow limitation should be used to determine 
the GOLD stage of the patient [P11-05865]:
GOLD Stage
Severity of Disease
Degree of airflow limitation 
(FEV1)
GOLD 2
Moderate
50% ≤ FEV1 < 80%
GOLD 3
Severe
30% ≤ FEV1 < 50%
Additional clinic visits will be scheduled after 3 and 6 weeks of treatment (visits 5 and 6 
respectively). The first treatment period will be followed by a 3-week wash-out period and then 
the second treatment period will commence (visits 7-9). Patients will be evaluated for an 
additional 21 days following completion of the last 6-week treatment period, or, in case of early 
discontinuation, after the final dose of study medication. The patient’s trial participation will be 
concluded with the follow-up visit 21 days after the end of treatment. For visit details please 
refer to section 6.2.
All study-related documentation will be stored in the BI clinical trial master file (TMF). Trial 
relevant documentation for the study sites will be filed in the ISF at the investigational sites.

Sponsor: BI has appointed a Trial Clinical Monitor (TCM), responsible for coordinating all 
required activities, in order to:
•
manage the trial in accordance with applicable regulations and internal Standard 
Operating Procedure (SOPs),
•
direct the clinical trial team in the preparation, conduct, and reporting of the trial,
•
ensure appropriate training and information of local clinical monitors (CML), Clinical 
Research Associates (CRAs), and investigators of participating countries.
The organisation of the trial in the participating countries will be performed by the respective 
local or regional BI-organisation (Operating Unit, OPU) in accordance with applicable 
regulations and internal SOPs, or by a Contract Research Organisation (CRO) with which the 
responsibilities and tasks will have been agreed and a written contract filed before initiation of 
the clinical trial.
Data Management and Statistical Evaluation will be done by BI according to BI SOPs.
Tasks and functions assigned in order to organise, manage, and evaluate the trial will be defined 
according to BI SOPs. A list of responsible persons and relevant local information can be found 
in the ISF.
Coordinating Investigator: A coordinating investigator will be nominated and will be responsible 
to coordinate investigators at different centres participating in this multicentre trial. Tasks and 
responsibilities will be defined in a contract. Relevant documentation on the participating 
(principal) investigators and other important participants, including their curricula vitae, will be 
filed in the ISF.
Targeted group of Investigators: Pulmonologists/qualified sites with experience in conducting 
studies involving exercise in patients with COPD and access to the desired patient population. 
Local Facilities/Equipment: The following local facilities/equipment is required at the 
investigational site: 
•
scale and sphygmomanometer,
•
a spirometer which meets ATS Criteria [P05-12782],
•
a portable pulse oximeter for use during exercise testing,
•
body plethysmograph,
•
a standard 12-lead electrocardiogram (ECG),
•
access to local lab facility for safety testing.

appropriate re-supply of medication to patients. The ability to unblind will be available to the 
investigator via the IRT. Details will be provided in IRT Manual available in the ISF.
Mobile cardiopulmonary exercise equipment: Will be leased by the sponsor for all sites for the 
duration of the trial. The provision of this equipment will be handled by BI and an external 
vendor.
All contracts and relevant meeting minutes will be stored by BI in the TMF.
DISCUSSION OF TRIAL DESIGN, INCLUDING THE CHOICE OF 
3.2
CONTROL GROUP
Randomisation will be used to avoid systematic differences between groups with respect to 
patient characteristics that could affect the outcomes of interest.  The double-blind design will be 
used to ensure that patients, investigators and BI personnel are unaware of each patient’s 
assigned treatment, thus minimising any potential biases resulting from differences in 
management, treatment or assessment of patients, or interpretation of results that could arise as a 
result of patient or investigator knowledge of the assigned treatment [R03-2273].
The cross-over design allows for each patient to serve as his/her own control. As such, treatment 
comparisons are within patient rather than between patients, which removes the inter-patient 
variability from the comparison between treatment regimens [R94-1529].
A 6 week treatment period is considered sufficient to evaluate the effects of tiotropium +
olodaterol FDC at pharmacodynamic steady state (based on results from previous studies 
evaluating the effects of tiotropium + olodaterol FDC on spirometric parameters).
The restriction of long-acting β2-agonist and a long-acting anti-cholinergic during the run-in 
period is necessary to determine the appropriate speed for the 3min CSST, perform the practice 
3min CSST, and measures of breathlessness.  
During the run-in and treatment periods, patients will continue to receive treatment with ICS as 
required. Short-acting β2-agonist medication (salbutamol / albuterol) will be provided to all 
patients for rescue use, and appropriate medications will be allowed to control acute 
exacerbations as medically necessary. Ipratropium may be provided to patients who are required 
to wash out of LAMAs during the run-in and washout periods. 
Eligible patients may be randomised to a treatment arm that includes both a LABA(olodaterol) 
and a LAMA (tiotropium), therefore it is necessary to restrict the use of LABAs (e.g. salmeterol,

formoterol, indacaterol, olodaterol) and anti-cholinergics (e.g. tiotropium, ipratropium) during 
the treatment period. 
The inclusion of the tiotropium 5 µg monotherapy treatment arm allows for an appropriate 
comparison of the combination product to the commonly used individual product to determine 
the additional effect of adding LABA to an anticholinergic on breathlessness.
SELECTION OF TRIAL POPULATION
3.3
A sufficient number of patients will be enrolled (sign informed consent) at approximately 15
sites to ensure that a minimum of 102 patients of either sex, 40 to 75 years of age, with a 
diagnosis of COPD are randomised into the study. 
Enrolment will be competitive. Additional sites may be initiated and 'non-productive' sites may 
be closed to ensure sponsor's timelines.  The distribution of patients between countries will be 
dependent on the access to the suitable patient population as well as the operational feasibility of 
performing the trial in the country.  It is anticipated that each site will enrol an average of 
approximately 8 patients. 
Patients will be required to perform shuttle tests on several occasions during the trial. For this 
reason, patients with any contraindication to exercise as stipulated in the ERS guidelines [R98-
0973], and supported by the ATS/American College of Chest Physician (ACCP) guidelines 
[P03-01262] will be excluded from participation. 
A log of all patients enrolled into the trial (i.e. who have signed informed consent) will be 
maintained in the ISF at the investigational site irrespective of whether they have been treated 
with investigational drug or not.
3.3.1

4.1.2
Method of assigning patients to treatment groups
During visit 4 and after the patient’s eligibility has been confirmed, the treatment sequence will 
be assigned via a third party phone/web-based system.  This will involve the use of an IRT
system which will implement a randomisation scheme generated using a validated system. 
Access to the codes will be controlled and documented. All necessary instructions for using the 
IRT system will be described in a user guide/manual, a copy of which will be available in the 
ISF.
Note that the Respimat® treatment box numbers assigned to the patient by the IRT is different 
from the study patient number assigned by the Remote Data Capture (RDC) system upon signing 
informed consent.
4.1.3
Selection of doses in the trial
The clinical trials conducted during the Phase III program for tiotropium + olodaterol FDC 5/5 
μg have shown that this dose is a safe, well tolerated and efficacious combination therapy. The 
observed incremental bronchodilator response for the combination compared to the individual 
components translated into benefits that were meaningful to the patient, with improvements in 
several patient centred outcomes. 
At the time of the final protocol for 1237.28, tiotropium + olodaterol  FDC (5/5 µg) delivered by 
the Respimat® Inhaler has been approved in Belgium, Canada, Germany, Netherlands, as well as

the US and several other countries. Therefore the marketed dose is considered to be the 
appropriate dose to be studied in this trial. 
Tiotropium 5μg (2.5 μg / per actuation) inhalation solution Respimat® has been approved in more 
than 80 countries worldwide including Europe, US, Canada and Japan as an antimuscarinic 
bronchodilator with a once daily posology. Therefore the marketed dose of tiotropium Respimat®
is deemed an adequate comparator for the study.
4.1.4
Drug assignment and administration of doses for each patient
Trial medication will be dispensed to the patient by the investigator/pharmacist or designee. At 
visit 4 eligible patients will be randomised to one of two double-blinded treatment sequences 
(1:1 ratio) by the IRT. At visits 4 and 7, the IRT will assign 3 Respimat® treatment boxes to each 
patient. Each Respimat® treatment box consists of a Respimat® inhaler and a cartridge and will 
have a unique medication number with 6 digits.
One of the Respimat® treatment boxes is a reserve Respimat® inhaler. The reserve kit allows the 
patient the flexibility of not having to return to the clinic immediately to replace a lost or 
malfunctioning Respimat® inhaler. In the event that a patient may need additional extra 
Respimat® inhalers and cartridges due to rescheduled visits, inhaler loss or malfunction, these 
will be supplied on an ‘on demand’ basis. Dispensing of these extra Respimat® inhalers will also 
be managed via the IRT.
Site personnel will enter all medication numbers dispensed to each patient in the Medication
Record page of the eCRF.
4.1.4.1 
Priming of the Respimat® inhaler
Each newly assembled Respimat® inhaler has to be primed when appropriate. The Respimat®
inhaler should be primed by actuating it until an aerosol is visible plus three additional 
actuations. All priming actuations should be directed to the ground and priming should NOT take
place in the same room where the patient is inhaling trial medication.
Once assembled, the shelf-life of the Respimat® inhaler with study medication or training 
medication (placebo) is 3 months. Therefore it is important to ALWAYS enter the date of the 
cartridge insertion on the medication label of the Respimat® inhaler immediately after the 
cartridge is inserted.
For detailed priming instructions please refer to the Respimat® inhaler handling instructions
in Appendix 10.1

4.1.4.2 
Study medication administration
At visit 4 the study medication will be self-administered between 7:00 a.m. and 10:00 a.m. At 
subsequent clinic visits, study medication will be self-administered preferably within ±30 
minutes of time of administration at visit 4 AND between 7:00 a.m. and 10:00 a.m. The clock 
time of the start of inhalation of study medication will be captured on the source documents and 
in the eCRF. 
The utmost care should be taken to ensure that during the treatment period, the study medication 
is not taken prior to coming to the site for a visit. 
At visits 6 and 9 (last visit of each treatment period), the Respimat® Inhaler that is in current use, 
must be used for administration of the study medication at that visit since no new Respimat®
treatment box will be assigned.
When planning the time of the morning dose of study medication at visit 4, site personnel should 
discuss with the patient about the preferred regular time of day that the patient will be taking the 
morning dose of study medication at home. 
Study medication administration at clinic visits
Dispensation and Respimat® inhaler assembling
Trial medication will be dispensed at visits 4 and 7. Patients will receive 2 new Respimat®
treatment boxes + 1 Respimat® inhaler reserve. During the clinic visit only one new Respimat®
inhaler should be primed (= cartridge inserted and primed) under the oversight of the site staff. 
The other Respimat® inhalers should NOT be assembled prior to leaving the clinic.
Drug administration
At each clinic visit, oral inhalation of two puffs of the study medication from the new assigned 
Respimat® inhaler will be self-administered by the patient under the direct supervision of the 
investigating physician or designee. The investigator or qualified study personnel will observe 
the inhalation procedure. For training session please refer to section 4.1.4.3.
Respimat® inhalers return
At visits 6 and 9 all used and unused Respimat® inhalers will be returned to the clinic by the
patient. The reserve Respimat® inhaler should also be returned at each clinic visit to be replaced 
if it has been used or primed.
For rescue medication dispensation, please refer to section 4.2.1
Study medication administration at home
Each morning, oral inhalation of two puffs on the study medication from the assigned Respimat®
inhaler will be self-administered by the patient. Patients should be encouraged to take their study

medication at approximately the same time in the morning (morning dose window until noon). If 
a patient misses the daily dose he/she should take the next dose the day after. The patient must 
assemble and prime the Respimat® inhaler at home once the current used Respimat® inhaler is 
empty and the device is locked.
4.1.4.3 
Inhaler devices training
SPECIAL CONSIDERATION:
Most severe to very severe COPD patients are currently using different inhalation medications at 
the same time. This may cause technical challenges and affect their treatment adherence. 
Respimat®
Training on the use of the Respimat®inhaler will be provided to patients.
•
At visit 1: The first patient’s training session will be performed with the intention
to familiarise the patient with the Respimat®inhaler training medication (placebo). 
Detailed written instructions for the use of the Respimat® inhaler will also be given. (See 
Appendix 10.1).
•
At visit 4: After randomisation, the patient’s training session will be performed from the 
new assigned Respimat® inhaler. Instructions on how to assemble and prime the 
Respimat® inhaler at home should also be reviewed.
•
At visit 7: Observance of the inhalation procedure will occur. The correct inhalation 
technique should be reinforced in case of inadequate use of Respimat® inhaler. It is also 
important to remind the patient on how to assemble and prime the Respimat®inhaler at 
home.
Rescue medication
Before using for the first time the salbutamol (albuterol) hydrofluoroalkane (HFA) MDI 
inhalation aerosol, one actuation should be released into the air to make sure the device is 
working. The patient’s inhaler technique should be reviewed and corrected if needed at each 
clinic visit.
Respimat® malfunctioning
4.1.4.4
Any Respimat® inhaler that has been reported as malfunctioning by a patient or investigator will 
be returned to BI for investigation. See the ISF for specific instructions and for details regarding 
drug accountability requirements. Details of the procedure for the return of malfunctioning 
inhalers are provided in Appendix 10.2.

Administration of rescue medication can occur at any point during the trial as deemed necessary 
by the patient or the investigator. Open label salbutamol / albuterol MDI (100 μg per puff) will 
be provided as rescue medication by BI; only the salbutamol / albuterol MDI provided by BI is 
allowed for rescue medication use. If the patient requires rescue medication during the PFT days 
(visits 4 - 9), the PFTs will be discontinued. The exercise testing should be rescheduled if 
possible. The medication used, route and 24-hour clock time of administration will be recorded 
on the Rescue Medication eCRF page. 
There are no special emergency procedures to be followed.
Medications allowed to control acute exacerbations as medically necessary during the treatment 
period:
•

ASSESSMENT OF EFFICACY
5.2
Constant Speed Shuttle Test
At all sites, an ISWT will be performed at visit 1 for each patient. The test will be conducted 
according to the methodology described by Singh et al [R04-4259] with IC and physiological 
parameters measured using the mobile cardiopulmonary exercise equipment. At visit 2, starting 
at 4 km/h, the patient will complete up to three x 3min CSST at different sets of speeds (2.5, 
3.25, 4, 5 or 6 km/h) to determine the highest speed that meet the following parameters:
•
The patient can complete the entire three minutes of the test, and
•
The patient achieves a BORG breathlessness rating of ≥ 4.
The test will be conducted according to the methodology developed by Maltais et al, [ P12-
12739]. This speed selected at visit 2 will be used for all subsequent tests.   At visit 3, a training 
3min CSST will be performed using the speed selected at visit 2. At visits 4 and 7, a period
baseline 3min CSST will be completed prior to dosing. At visits 5, 6, 8 and 9 a constant speed
test will be conducted 2 hours (+ 15 minutes) after inhalation of the study medication. 
 
 
 
 
 
 
 
 
 
 
The 3min CSST test methodology and speed selection is described in detail in Appendix 10.4
and manual of procedures.

Modified BORG Scale
Before, during and at end-exercise, patients will be asked to estimate the intensity of breathing
discomfort 
 that they are experiencing by matching their subjective estimate to 
descriptive phrases that best describe the intensity of each sensation using the MBS-S.  
Details of the MBS-S are provided in Appendix 10.5.
Pulmonary Function Testing
Spirometers and their use, including daily calibration, must meet ATS/ERS criteria [P05-12782]. 
Spirometry will be conducted using the site’s own equipment. Patient will be in a seated position 
and it is preferable that the same trained individual performs the PFT for a given patient. The 
best of three efforts will be defined as the highest FEV1 and the highest FVC each obtained on 
any of three manoeuvres meeting the ATS criteria (to a maximum of five attempts). The highest 
FEV1 and FVC will be selected regardless of whether they come from different spirometric 
manoeuvres or from the same manoeuvre. 
Predicted normal FEV1 values will be calculated for patients using the ECSC equations (R94-
1408, see Appendix 10.3). 
If a patient is unable to complete the PFTs during a visit, the CML should be notified as soon as 
possible. The eCRF will be completed indicating the reason for stopping testing, rescue 
medication given (if any) and time of rescue medication. Patients who are unable to complete the 
study visit may leave the clinic only upon instruction from the supervising physician.
Reversibility testing [P05-12782] will be performed for the qualifying PFT at the Screening visit 
(visit 1): the procedure is described in Appendix 10.3. The post-bronchodilator measurements 
must meet the inclusion criteria specified in section 3.3.2.
Inspiratory Capacity Measurements
IC measurements will be performed during exercise testing as follows: 

ISWT - at rest, during exercise and at the end of exercise

3min CSSTs – at rest and at the end of exercise
IC measurements will be taken using mobile cardiopulmonary exercise equipment capable of 
measuring IC during the shuttle tests.
For IC taken at rest prior to exercise, at least three reproducible measurements should be 
obtained with a maximum of 5 measurements to be performed. The resting IC should be 
recorded as the mean of the two highest acceptable efforts.
For additional details on the IC maneuvers, please refer to Appendix 10.7 and manual of 
procedures.

Body Plethysmography 
Constant-volume variable-pressure body plethysmography will be used in the trial at visit 1 to 
assess eligibility and parameters to be measured will be FRC, IC and total lung capacity (TLC). 
Measurements should be done in triplicate. The mean FRC value from the three manoeuvres will 
be recorded. The largest IC will be recorded. TLC will be calculated as mean FRC + largest IC.
Body plethysmography should be done before spirometry. 
CRQ Questionnaires
The CRQ questionnaires should be administered at the visits outlined in the FC and completed 
by the patients.  They should be completed first during a study visit, prior to dosing and all study 
procedures.  The CRQ-SAI should be completed prior to the CRQ-SAS. Please see Section 6.2
for the detailed order of administration of questionnaires at each visit.
The CRQ-SAS is a questionnaire that assesses the patients’ perception of their COPD and 
measures the impact of COPD on their life. The CRQ-SAS refers to the CRQ-Self-administered 
format and contains 20 standardised dyspnea questions. The first part of the questionnaire 
contains 5 standardized activities and the patients must indicate how much shortness of breath 
they have experienced while performing each of the activities.

Patients will also complete the CRQ-SAI questionnaire which contains a dyspnea domain 
that is individualized to each patient.  Dyspnea items may be selected from a list of 26 
suggested items or may be written in by the patients. The patients are asked to select the 5 
activities associated with breathlessness that they perform frequently and are most important 
to them.

Details of the CRQ-SAS are provided in Appendix 10.9.

5.3.2
Vital Signs
Measurements of heart rate and blood pressure will be obtained immediately prior to forced 
spirometry measurement (FEV1 and FVC), with the patient seated and rested for a minimum of 5 
minutes.
5.3.3
Safety laboratory parameters
Safety laboratory testing will be conducted (non-fasting) on all patients at the screening visit 
(visit 1), and at visits 6 and 9 (or at the withdrawal visit if the patient does not complete all study 
visits). Follow-up clinical laboratory testing will be performed at visit 10 if there are any 
clinically significant findings at visit 9. The laboratory tests at visit 1 will be considered as the 
baseline measurements. Laboratory specimens will be collected in the morning prior to the 
exercise testing. Patients should be instructed not to do any unaccustomed physical exercise 36 
hours prior to laboratory testing. 
Haematology, blood chemistry and ß-HCG will be analysed by the local laboratory of each 
participating site or, where appropriate, locally selected central laboratory. Laboratory data will 
be collected but not captured in the eCRF or transferred to the sponsor. It is the responsibility of 
the investigator to evaluate changes in laboratory values and reporting of adverse event should be 
followed according to the definitions outlined in section 5.3.6.1.
Haematology
Haemoglobin, haematocrit, red blood cell count, white blood cell count including differential 
(neutrophils, lymphocytes, monocytes, eosinophils, basophils), total eosinophil count and platelet 
count.
Blood chemistry
Alkaline phosphatase, Lactate Dehydrogenase (LDH), Gamma-Glutamyl Transpeptidase 
(Gamma-GT), Serum glutamic-oxaloacetic transaminase (SGOT), Serum glutamic-pyruvic 
transaminase (SGPT), glucose, calcium, inorganic phosphorus, uric acid, urea nitrogen, 
creatinine, total protein, potassium, sodium, chloride, total bilirubin, creatinine phosphokinase.
Pregnancy Testing
A serum human chorionic gonadotropin (HCG) test will be done at visit 1 in all females of 
childbearing potential. Urine pregnancy testing will be performed at visit 4, 6, 7, 9, and 10 in 
females of childbearing potential.

5.3.4
Electrocardiogram
A standard 12-lead ECG at rest will be performed on all patients at visits 1, 6 and 9. An ECG 
will be repeated at visit 10 in case of any findings at visit 9.
The purpose of the screening ECG (visit 1) is to obtain information about the patient´s baseline 
conditions that may have not been elicited in obtaining the baseline conditions. Therefore, any 
significant findings from the examination are recorded on the Baseline Condition page.
ECG will be completed using site´s own equipment and ECG data will not be collected or 
captured in the eCRF. It is the responsibility of the investigator to evaluate the ECG and 
reporting of adverse events should be followed using the definitions outlined in section 5.3.6.1.
In case of indication of a disease listed under the exclusion criteria, the patient should not be 
randomised for treatment.

Assessment of adverse events
Definitions of AEs 
5.3.6.1
Adverse event
An adverse event (AE) is defined as 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 unfavourable and unintended sign (including an abnormal laboratory 
finding), symptom, or disease temporally associated with the use of a medicinal product, whether 
or not considered related to the medicinal product.
Adverse reaction
An adverse reaction is defined as a response to ta medicinal product which is noxious and 
unintended.  Response in this context means that a causal relationship between a medicinal 
product and an adverse event is at least a reasonable possibility.  Adverse reactions may arise 
from use of the product within or outside the terms of the marketing authorisation or from 
occupational exposure.  Conditions of use outside the marketing authorization include off-label 
use, overdose, misuse, abuse and medication errors.

or
•
is to be deemed serious for any other reason if it is an important medical event when 
based upon appropriate medical judgment which may jeopardize the patient and may 
require medical or surgical intervention to prevent one of the other outcomes listed in the
above definitions.
Medical and scientific judgment should be exercised in deciding whether other situations should 
be considered serious reactions, such as important medical events that might not be immediately 
life threatening or result in death or hospitalisation but might jeopardise the patient or might 
require intervention to prevent one of the other outcomes listed above.  Examples of such events 
are intensive treatment in an emergency room or at home for allergic bronchospasm, blood 
dyscrasias or convulsions that do not result in hospitalisation or development of dependency or 
abuse.  Any suspected transmission via a medicinal product of an infectious agent is also 
considered a serious adverse reaction.
AEs considered “Always Serious”
Cancers of new histology and exacerbations of existing cancer must be reported as a serious 
event regardless of the duration between discontinuation of the drug and the occurrence of the 
cancer.
In accordance with the European Medicines Agency initiative on Important Medical Events, 
Boehringer Ingelheim has set up a list of AEs, which by their nature, can always be considered to 
be “serious” even though they may not have met the criteria of an SAE as given above.
The latest list of “Always Serious AEs” can be found in the RDC.  These events should always 
be reported as SAEs.
Adverse events of special interest (AESIs)
No AESIs have been defined for this trial.
Intensity of AEs
The intensity of the AE should be judged based on the following:
Mild:
Awareness of sign(s) or symptom(s) that is/are easily tolerated

Moderate:
Enough discomfort to cause interference with usual activity
Severe:
Incapacitating or causing inability to work or to perform usual activities
Causal relationship of AEs
The definition of an adverse reaction implies at least a reasonable possibility of a causal 
relationship between a suspected medicinal product and an adverse event.  An adverse reaction, 
in contrast to an adverse event, is characterised by the fact that a causal relationship between a 
medicinal product and an occurrence is suspected.
Medical judgment should be used to determine the relationship, considering all relevant factors, 
including pattern of reaction, temporal relationship, de-challenge or re-challenge, confounding 
factors such as concomitant medication, concomitant diseases and relevant history.
Yes:
There is a reasonable causal relationship between the investigational product 
administered and the AE.
No:
There is no reasonable causal relationship between the investigational product 
administered and the AE.

Arguments that may suggest that there is a reasonable possibility of a causal relationship could 
be: 

The event is consistent with the known pharmacology of the drug

The event is known to be caused by or attributed to the drug class

A plausible time to onset of the event relative to the time of drug exposure

Evidence that the event is reproducible when the drug is re-introduced

No medically sound alternative etiologies that could explain the event (e.g. pre existing 
or concomitant disease, or co-medications)

The event is typically drug-related and infrequent in the general population not exposed 
to drugs (Stevens-Johnson Syndrome)
Arguments that may suggest that there is no reasonable possibility of a causal relationship could 
be: 

No plausible time to onset of the event relative to the time of drug exposure is evident 
(e.g. pre-treament cases, diagnosis of cancer or chronic disease within days/weeks of 
drug administration; an allergic reaction weeks after discontinuation of the drug 
concerned)

Continuation of the event despite the withdrawal of the medication taking into account 
the pharmacological properties of the compound (e.g. after 5 half-lives). Of note, this 
criterion may not be applicable to events whose time course is prolonged despite 
removing the original trigger

Additional arguments amongst those stated before, like alternative explanation (e.g. 
situations where other drugs or underlying disease appear to provide a more likely 
explanation for the observed event than the drug concernted)

Disapperance of the event event though the study drug treatment continues or remains 
unchanged 
5.3.7
Adverse event collection and reporting
AE Collection
The Investigator shall maintain and keep detailed records of all AEs in their patient files.
The following must be collected and documented on the appropriate eCRF by the investigator:
•
From signing the informed consent onwards through the Residual Effect period (REP), 
until individual patient’s end of trial:
o
All AEs (serious and non-serious).
•
After the individual patient’s end of trial: 
o
The Investigator does not need to actively monitor the patient for AEs but should 
only report relevant SAEs of which the Investigator may become aware of.

Proprietary confidential information © 2016 Boehringer Ingelheim International GmbH or one or more of its affiliated companies
The REP is defined as 21 days after the last trial medication application. All AEs which occurred 
through the treatment phase and throughout the REP will be considered as on treatment please 
see section 7.3.3. Events which occurred after the REP will be considered as post treatment 
events.
AE reporting to sponsor and timelines
The investigator must report SAEs and non-serious AEs which are relevant for the reported SAE
on the BI SAE form via fax immediately (within 24 hours ) to the Sponsor’s unique entry point 
(country specific contact details will be provided in the ISF). The same timeline applies if 
follow-up information becomes available. In specific occasions the investigator could inform the 
Sponsor upfront via telephone. This does not replace the requirement to complete and fax the BI 
SAE form.
Information required
For each AE, the investigator should provide the information requested on the appropriate eCRF 
pages and the BI SAE form. The Investigator should determine the causal relationship to the trial 
medication and any possible interactions between the investigational drugs and a Non-
Investigational Medicinal Product (NIMP)/Auxiliary Medicinal Product (AMP).
The following should also be recorded as an SAE in the eCRF and SAE form (if applicable):
•
Worsening of the underlying disease or of other pre-existing conditions.
•
Changes in vital signs, ECG, physical examination and laboratory test results, if they are 
judged clinically relevant by the Investigator.
If such abnormalities already pre-exist prior trial inclusion they will be considered as baseline 
conditions.

All (S)AEs, including those persisting after individual patient’s end of trialmust be followed up 
until they have resolved, have been sufficiently characterized, or no further information can be 
obtained.
Pregnancy
In rare cases pregnancy might occur in a clinical trial.  Once a patient has been enrolled into a 
clinical trial after having taken trial medication the investigator must report immediately (within 
24 hours) a potential drug exposure during pregnancy to the sponsor’s unique entry point 
(country specific contact details will be provided in the ISF). The Pregnancy Monitoring Form
for Clinical Trials (Part A) should be used.   
The outcome of the pregnancy associated with the drug exposure during pregnancy must be 
followed up and reported to the Sponsor’s unique entry point on the Pregnancy Monitoring Form 
for Clinical Trials (Part B). 
As pregnancy itself is not to be reported as an AE, in the absence of an accompanying SAE, only 
the Pregnancy Monitoring Form for Clinical Trials and not the SAE form is to be completed. If 
there is an SAE associated with the pregnancy then the SAE has to be reported on the SAE form 
in addition. 
The ISF will contain the Pregnancy Monitoring Form for Clinical Trials (Part A and B).

Modified Medical Research Council Dyspnea Scale 
The mMRC Dyspnea Scale uses a simple grading system to assess a patient´s level of dyspnea. 
All questions relate to everyday activities and are generally easily understood by patients. Scores 
range from 0 (none) to 4 (very severe) and are usually obtained in a few seconds. Patients will be 
asked to score their dyspnea at Visit 1.
 
 
 
  
APPROPRIATENESS OF MEASUREMENTS
5.7
Measurements of efficacy parameters will be consistent with the following generally recognized 
standards: 
Shuttle Test
The ISWT will be conducted according to the methodology described by Singh et al [R04-4259].
The 3min CSST will be conducted according to the methodology developed by Maltais et al
[P12-12739].
Spirometry
PFTs are a validated and well established measurement tool for lung function testing. PFTs will 
be conducted at clinic visits using the site’s own equipment which meets ATS/ERS criteria [P05-
12782]. FEV1, FVC and IC are standard measurements for the assessment of lung function.
Body Plethysmography 
Constant-volume variable-pressure body plethysmography will be used in the trial following the 
methodology and calibration procedures described by Coates et al. 1997 [R98-1487].

INVESTIGATIONAL PLAN
VISIT SCHEDULE
6.1
Patients should make every attempt to complete the protocol as specified. Investigators should 
encourage patient treatment compliance and adherence to other protocol specific activities. All 
deviations from the planned visit schedule will be documented. Refer to the FC for time 
windows for the visits. After this, a discussion with the Clinical Monitor should take place
regarding the patient continuing in the trial.
Rescheduling in general
A patient may be rescheduled twice (within one week of the scheduled visit date) due to lack of 
medication washout compliance or no intake of study medication on the day preceding the clinic 
visit.
Rescheduling prior to randomisation
The screening period (between visit 1 and visit 4) may be extended by an additional 2 weeks for 
administrative reasons.
If a patient experiences a COPD exacerbation or respiratory tract infection in the 6 weeks prior to 
visit 1, the visit will be postponed until 6 weeks following recovery from the infection or 
exacerbation. 
If a patient experiences a COPD exacerbation or respiratory tract infection during the screening 
period (between visit 1 and 4), randomisation will be postponed until 6 weeks following 
recovery from the infection or exacerbation. To be eligible, patients should be clinically stable in 
the opinion of the investigator for 3 weeks prior to the randomisation visit. 
If the screening period is extended by more than an additional 4 weeks, but not more than an 
additional 8 weeks, the screening examination has to be repeated prior to randomisation. The 
repeat screening examination will include a physical examination, vital signs (blood pressure and 
pulse rate), 12-lead ECG and clinical laboratory evaluation (haematology, serum chemistry, and 
pregnancy test). The patient should return for these evaluations 2 weeks prior to the re-scheduled 
randomisation visit (visit 4). All AEs and concomitant therapies will be recorded. If the 
screening period is to be extended more than an additional 8 weeks, the sponsor should be 
contacted. A decision whether the patient can continue in the trial will be made on a case by case 
basis. Clinically unstable COPD should be considered as a reason for discontinuation of the 
patient.
Refer to sections 4.2.1 and 4.2.2 for details on medications allowed to control COPD 
exacerbations and restrictions for these medications prior to PFTs.

Rescheduling after randomisation 
Subsequent visits should always be planned to take place to assure a minimum 6 week treatment 
period and a minimum 3 week wash-out period between treatment periods.
If rescheduling of visits after randomisation is necessary, the total daily doses of the Respimat®
inhaler need to be obeyed. Reserve medication is dispensed at each treatment period to avoid 
intermediate visits.
If rescue medication is administered during a visit day within 8 hours prior to administration of 
trial medication, the visit will be rescheduled once. Further rescheduling should be discussed 
with the CML. 
Refer to sections 4.2.1 and 4.2.2 for details on medications allowed to control acute COPD 
exacerbations and restrictions for these medications prior to PFTs.
In case a visit needs to be rescheduled outside the allowed time window (e.g. in order to meet 
PFT wash-out requirements following treatment of an acute exacerbation), the CML should be 
contacted.

Screening and run-in period
Screening Period
If there is any indication during the screening period that the patient is not stable enough, in the 
opinion of the investigator, to complete the trial or that the patient will be non-compliant with the 
trial medication or restrictions, the patient should not be randomised. This evaluation should be 
completed by the investigator.
Details of any patient who is screened for the trial but is found to be ineligible must be entered in 
the enrolment log and documented in the eCRF.
Patients must satisfy all inclusion and not meet any of the exclusion criteria prior to 
randomisation at visit 4 (see section 3.3.2 and section 3.3.3).

STATISTICAL METHODS AND DETERMINATION OF
SAMPLE SIZE
STATISTICAL DESIGN - MODEL
7.1
This is a randomised, double-blind, cross-over study to determine the effect of 6 weeks treatment 
of orally inhaled tiotropium + olodaterol FDC (5/5 µg) delivered by the Respimat® Inhaler, on 
breathlessness during the three minute shuttle test in patients with COPD.  The effect of two 
treatments (T+O vs. tiotropium) in this cross-over study will be compared.
Based on these design considerations, a mixed effect repeated measures model (MMRM) with 
treatment and period as fixed effects and patient as a random effect will be used for the primary 
analysis. Detailed specifications will be provided in section 7.3. 
NULL AND ALTERNATIVE HYPOTHESES
7.2
The following hypotheses (two-sided α = 0.05) will be tested for the primary endpoint – change 
from baseline in intensity of breathlessness measured using the MBS-S at the end of the 3min 
CSST - after 6 weeks of treatment.
H0: Mean MBS-S3 for (Tiotropium + Olodaterol) = Mean MBS-S3 for Tiotropium
H1: Mean MBS-S3 for (Tiotropium + Olodaterol) ≠ Mean MBS-S3 for Tiotropium
Where MBS-S3 is the primary endpoint, the MBS-S at the end of the 3 minute shuttle test after 6 
weeks of treatment. 
PLANNED ANALYSES
7.3
The efficacy analysis will be performed in all randomised patients who were documented to have 
received any dose of trial medication and who have both baseline and any evaluable post-
baseline measurement for the primary endpoint. This set will be called Full Analysis Set (FAS).
All randomised patients taking any dose of the trial medication will be included in the safety 
evaluation (Treated Set).
The handling of randomised patients who received the wrong treatment will be specified in the 
TSAP.

7.3.1
Primary endpoint analyses
In the primary analysis, the two-sided hypotheses as given in section 7.2 will be tested based on 
MBS-S using a restricted maximum likelihood (REML)-based MMRM. This model will include 
treatment and period as fixed effects, patient as a random effect and period baseline as well as 
patient baseline as covariates. Compound symmetry will be used as a covariance structure for 
within patient variation. The SAS procedure MIXED will be used involving the restricted 
maximum likelihood estimation and the Kenward-Roger approximation for denominator degrees 
of freedom. This approach is described in [R10-4391]. Adjusted mean values as well as 
treatment contrasts will be presented together with the 95% confidence intervals (CI) and p-
values.
Period baseline
The period baseline is defined as the pre-dose measurement, the MBS-S at the end of the 3 
minute CSST, performed prior to dosing on the first day of each period.
Patient baseline
The patient baseline is defined as the mean of non-missing period baselines for each patient.
7.3.2
Secondary endpoint analyses
The MMRM model described for the primary analysis will be performed for secondary 
endpoints as listed in section 5.1. Adjusted mean values as well as treatment contrasts will be 
presented together with the 95% CI. All calculated p-values should be considered descriptive for 
the analysis of the secondary endpoints.
7.3.3
Safety analyses
Adverse events will be coded using the Medical Dictionary for Regulatory Activities (MedDRA) 
coding dictionary. Standard BI summary tables and listings will be produced. All adverse events 
with an onset between start of treatment and end of the residual effect period (REP), a period of 
21 days after the last dose of trial medication, will be assigned to the treatment period for 
evaluation.
All treated patients will be included in the safety analysis. In general, safety analyses will be 
descriptive in nature and will be based on BI standards. No hypothesis testing is planned.
Statistical analysis and reporting of adverse events will concentrate on treatment-emergent 
adverse events. To this end, all adverse events occurring between start of treatment and end of 
the residual effect period will be considered ‘treatment-emergent’.  The residual effect period is 
defined as 21 days after last dose of study medication (separately for each treatment period in the

crossover). Adverse events that start before first drug intake and deteriorate under treatment will 
also be considered as ‘treatment-emergent’.
Frequency, severity, and causal relationship of adverse events will be tabulated by system organ 
class and preferred term after coding according to the current version of MedDRA.
Blood pressure and pulse rate measured in conjunction with PFT testing will be presented for 
each treatment using descriptive statistics. 
7.3.4
Pharmacokinetic analyses
No pharmacokinetic analysis is planned.
INTERIM ANALYSES
7.4
No interim analysis is planned.
HANDLING OF MISSING DATA
7.5
In general, missing data at a given visit will be imputed by the available data from the patient at 
that visit and completely missing visits will be handled through the statistical model.
Additional details on the imputation of missing data will be specified in the Trial Statistical 
Analysis Plan (TSAP) prior to unblinding.
RANDOMISATION
7.6
Patients will be randomised in blocks to double-blind treatment. Approximately equal numbers 
of patients will be randomised to each treatment sequence. BI will arrange for the randomisation
and the packaging and labelling of trial medication. The randomisation list will be generated 
using a validated system, which involves a pseudo-random number generator so that the resulting 
treatment will be both reproducible and non-predictable. The block size will be documented in 
the CTR. Access to the codes will be controlled and documented.
IRT will also be set-up to ensure that the number of GOLD Stage II patients is capped at 
approximately 50% and the number of GOLD Stage III patients is capped at approximately 50%.

DETERMINATION OF SAMPLE SIZE
7.7
Based on a pilot study [P12-12739], the standard deviation of within-subject treatment difference
(measured by 10-point modified BORG scale) for 3min CSST is approximately 1.776 for COPD 
patients. The pilot study was a placebo controlled, double-blind cross-over study in patients with 
COPD to investigate the effect of administration of 500 μg nebulized ipratropium bromide vs. 
saline placebo. It is deemed reasonable to assume that the variability for within-patients 
difference should be similar for this trial.
Assuming a delta of 0.5 BORG units and various choices of power, nQuery Advisor® 7.0 
MOT0-1 (one-sample t-test) yielded the following results.
Table 7.7: 1
Total calculated sample size
Power
Std. Dev. (1.776)
80%
101
90%
135
Since patient drop out over 12 weeks of treatment is expected to be quite low and the MMRM 
model specified for the primary analysis naturally accounts for missing data, there has been no 
sample size inflation to account for patient attrition in the sample size calculations. Based on the 
standard deviation of 1.776 and a type one error rate of 0.05 (two-sided), the ability to detect a 
difference of 0.5 BORG units would require a sample size of 101 to maintain 80% power to 
reject the null hypothesis. Since there are two sequences of treatments, the sample sizes are 
rounded up to the nearest even number. The required sample size is 102.

When to get a new Respimat® inhaler
The Respimat® inhaler contains 60  puffs (30 medicinal doses). The 
dose indicator shows approximately how much medication is left.  
When the pointer enters the red area of the scale, there is, 
approximately, medication for 7 days (14 puffs) left.  
Once the dose indicator has reached the end of the red scale (i.e. all 30
doses have been used), the Respimat® inhaler is empty and locks 
automatically. At this point, the base cannot be turned any further. 
What if...
What if...
Reason
What to do
I can’t turn the base easily.
a) 
The Respimat®
inhaler is already prepared 
and ready to use. 
b) 
The Respimat®
inhaler is locked after 60 
puffs (30 doses).
a) 
The Respimat®
inhaler can be used as it is.
b) 
Prepare and use your 
new  Respimat® inhaler.
I can’t press the dose 
release button.
The clear base has not been 
turned.
Turn the clear base until it 
clicks. (half a turn)
The clear base springs back 
after I have turned it.
The clear base was not 
turned far enough.
Prepare the Respimat®
inhaler for use by turning 
the clear base until it 
clicks. (half a turn)
I can turn the clear base 
past the point where it 
clicks.
Either the dose release 
button has been pressed, or 
the clear base has been 
turned too far.
With the grey cap closed, 
turn the base until it clicks. 
(half a turn) 
How to care for your inhaler
Clean the mouthpiece including the metal part inside the mouthpiece with a damp cloth or tissue only, at 
least once a week.
Any minor discoloration in the mouthpiece does not affect the performance of your Respimat® inhaler.
  
If necessary, wipe the outside of your Respimat® inhaler with a damp cloth.

ADDITIONAL INFORMATION REGARDING IN/EX CRITERIA
10.3
Reversibility testing [P05-12782]
At the screening visit (visit 1), following the completion of three acceptable pre-bronchodilator
forced expiratory manoeuvres, salbutamol (albuterol) will be administered to each patient in 
order to document the degree of reversibility. Immediately after (within 10 min) pre-
bronchodilator forced expiratory manoeuvres and after a gentle and incomplete expiration, a
dose of 100 μg of salbutamol (albuterol) is inhaled in one breath to TLC. The breath is then 
held for 5–10s before the patient exhales. Four separate doses (total dose 400 μg) are delivered 
at approximately 30-second intervals (this dose ensures that the response is high on the
salbutamol (albuterol) dose–response curve). Three additional, acceptable post-bronchodilator 
forced expiratory manoeuvre tests are recorded ≥10 min and up to 15 min later after the last 
dose of salbutamol (albuterol) is inhaled. !"# $%&'()*%+,"%-./0'%* 1#0&2*#1#+'& 12&' 1##' '"#

EXERCISE TESTING – ISWT AND 3MIN CSST
10.4
To supplement the information on exercise testing using the ISWT and 3min CSST described 
in this chapter, a Manual of Procedures (MOP) has been developed. More detailed information 
on the procedure, on staffing, site and equipment requirements, patient preparation, IC
measurements, and calculations etc. can be found in this MOP, which is filed in the ISF.
10.4.1
General considerations for exercise testing
Exercise performance variability
A number of physiological and psychological factors are known to affect exercise 
performance. Lack of attention to controlling these extraneous factors may result in an 
unacceptable degree of variability in exercise performance. As such, certain requirements have 
been put in place to reduce exercise performance variability:
Physiological:
Pre-exercise diet: Patients are to be encouraged to eat breakfast before coming to the clinic. 
However, patients should not eat within 2 hours of exercise tests.
•
Hydration state: Patients are to be encouraged to maintain an adequate hydration state 
during the morning of the exercise tests (i.e., drink lots of water).
•
Environmental conditions (temperature, humidity): Temperature and humidity should be 
controlled within the laboratory at comfortable levels, and should be recorded each 
testing day.
Previous exercise:
•
Fatigue: Patients should be encouraged to stay well-rested and to refrain from any 
strenuous, fatiguing or exhausting activities (e.g., walking up hills, walking up many 
flights of stairs, running, cycling, shovelling snow, strenuous household chores) on the 
morning of exercise tests.
•
Delayed onset muscular soreness (DOMS): Very strenuous, heavy type of activities, 
especially activities to which the patient is unaccustomed, can lead to muscle soreness 
24-48 hours after the activity. Patients should be encouraged to refrain from any type of 
heavy lifting, exhaustive digging in the garden etc., for 2-3 days prior to each clinic visit, 
especially if the patient has not performed these activities recently.
Psychological:
•
External motivational cues: Motivational cues provided to the patient can have profound 
effects on exercise performance. It is imperative that external motivational cues are 
controlled across patients and across sites.

Trial Protocol

Proprietary confidential information © 2016 Boehringer Ingelheim International GmbH or one or more of its affiliated companies
•
Time of exercise: No visual cues regarding the time of exercise should be provided to the 
patient. The patient’s watch should be removed prior to exercise, and all other 
timekeeping devices (e.g., trial staff watches, wall clocks, stopwatch etc.) should be kept 
away from the patient’s view.
•
Verbal encouragement: During exercise testing, the wording and intensity of verbal 
encouragement provided to the patient will be standardized, and will preferably only be 
provided by one member of the trial team, who is blinded to the results of the lung 
function tests. Appropriate positive words should be used to encourage the patient to 
continue walking. The tone of the encouragement should be enthusiastic and supportive, 
but not overbearing, overly loud or coercive in nature. Examples would be "good work", 
"well done", "excellent job so far" and "keep up the good work". Reinforcement could 
also consist of "that's a good walking rate" or, if the walking rate is dropping, "keep up 
the walking rate - that's great".
•
Familiarity with surroundings: Trial staff should allow as much time as necessary for the 
patient to become comfortable with the laboratory surroundings.
•
Distractions: During the exercise tests, access to the laboratory should be restricted to 
trial staff as much as possible. The noise level in the laboratory should be kept to a 
minimum, except for those sounds specifically related to the conduct of the test. This will 
ensure that the patient is able to concentrate on the task at hand, and will also ensure that 
the patient is attentive to the verbal encouragement provided by the designated member 
of the trial team.
•
Comfort with equipment: Patients should be appropriately dressed for exercise (e.g., 
shorts or track pants, gym shoes, T-shirt or sweat shirt), and trial staff should ensure that 
the patient is comfortable with the equipment prior to starting the exercise.
•
Familiarity with test: Before starting exercise, a member of the trial team should make 
sure that the patient is completely familiar with the type of exercise that is to be 
performed; for the incremental test, patients should be told that during the test they will 
have to walk progressively faster. For the constant speed tests, patients should be told that 
the speed of walking will be constant throughout the test. It is important that the patient
understands the difference between the incremental test and the constant speed tests.
•
For the ISWT: It is extremely important that the patient understands that there is no 
specific time limit to the exercise test, and that the test will continue as long as the patient
is able to. It must be stressed to the patient that the trial team will not stop the test unless 
there is concern for the patient’s safety, or the patient is unable to maintain the required 
walking pace.

•
Performance incentives: No external incentives for performance (i.e., rewards for 
performance) should be given to the patient, especially as the patient nears the point of 
limitation, but also prior to or at any time during the exercise.
Heart rate and safety monitoring:
•
Heart rate and oxygen saturation will be monitored during shuttle tests using a mobile 
pulse oximeter. 
•
Blood pressure will be determined before exercise, at end-exercise, five minutes after 
termination of exercise and when, for clinical reasons, it is required.
Personnel qualifications:
•
Exercise challenges should be conducted by adequately trained personnel with a basic 
knowledge of exercise physiology.
•
Technicians familiar with normal and abnormal responses during exercise and trained in 
CPR should be present throughout the test.
•
The supervising physician must be readily available to respond as needed. The degree of 
patient supervision should be increased if warranted by the clinical status of the patient.
Safety issues:
Cardiac (bradyarrhythmias, ventricular tachycardia, myocardial infarction, heart failure, 
hypotension, and shock) and non-cardiac (musculoskeletal trauma, severe fatigue, dizziness, 
fainting, body aches) complications of exercise challenges have been reported.
Consequently during the test, study personnel should be alert to any abnormal event.
Indications to stop the test must be clearly established and known by the personnel involved in 
testing.
Symptoms such as:
•
acute chest pain,
•
sudden pallor,
•
loss of co-ordination,
•
mental confusion,
•
extreme dyspnea.
If the exercise test has been stopped for one of these reasons, the patient should be monitored 
in the laboratory until signs / symptoms / ECG modifications have completely cleared. Full 
CPR equipment should be available in the laboratory. The patient will be withdrawn from the 
study.

10.4.2
Shuttle Test 
Shuttle tests will be performed in all patients of this trial. Selection of sites is based on past 
experience with the test and/or the availability of suitable infrastructure and qualified 
personnel. 
The shuttle test is performed on a flat, straight walking track, in a quiet treatment area that is at 
least 12 meters in length and approximately 2 meters wide, and clear of hospital traffic and 
obstacles. The standard instructions are given by trained site staff. Patients are required to 
walk, jog or run back and forth, in loops of 10 meters long. Cones are placed half a meter from 
the end, so they are 9 meters apart. The patient must keep pace with the pre-recorded auditory 
signal such that he/she completes a turn as each audio signal sounds.
Figure 10.4.2:1: Set up for the shuttle test
During the test oxygen saturation and heart rate will be monitored using a pulse oximeter 
(fingertip or ear lobe sensor).  Patients will also wear mobile cardiopulmonary exercise 
equipment. A chair should be placed in the immediate surroundings of the track for the patient 
to rest before and at the end of the test.
For the ISWT at visit 1, the end of the test will be signaled
a) by the patient, when he feels too breathless or fatigued to continue at the required speed.
b) by the operator when the patient fails to keep up to auditory signals after repeated 
warnings and encouragements (patient is more than 0.5 meter from the cone at the beep) 
and is unable to catch up within 3 shuttles.
c) when the patient is unable to continue safely (in the opinion of the supervising technician 
or physician).
For the 3min CSST, the end of the test will be signaled
a) by the patient, when he feels too breathless or fatigued to continue at the required speed.
b) by the operator when the three minutes of testing is completed.
c) by the operator when the patient fails to keep up to auditory signals after repeated 
warnings and encouragements (patient is more than 0.5 meter from the cone at the beep) 
and is unable to catch up within 3 shuttles.
d) when the patient is unable to continue safely (in the opinion of the supervising technician 
or physician).

The test should also be interrupted when symptoms occur as described in the safety section 
above.
Patient preparation:
•
Patients should not eat for at least 2 hours before any exercise challenge and should avoid 
caffeine-containing products the morning of and during the testing period.
•
Patients should dress appropriately for the exercise challenge (i.e., comfortable shoes and 
clothing).
•
On arrival in the laboratory, a detailed explanation of the testing procedure should be 
given to the patient, outlining the risks involved and potential complications (see safety 
issues section above).
•
Before exercise, blood pressure and heart rate are measured; the pulse oximetry sensor is 
carefully placed and secured to ensure good recordings. Nail polish and acrylic nails do 
not allow correct measurements and should be removed.
•
Good communication with the patient throughout the whole procedure increases the 
patient’s confidence and helps to ensure a good effort by the patient. Standardized 
instructions from the CD/ instruction sheet should be used during the test. Standardized 
and continuous encouragement to the patient should preferably be provided by only one 
member of the trial team who is blinded to the results of the spirometry.
Incremental Shuttle Walk Test
10.4.2.1
In addition to adhering to the general considerations for exercise challenges described above, 
the following specific procedures should be adhered to during the ISWT at visit 1:
The ISWT is a progressive test: the patient walks/jogs/runs up and down a 10 meter course at a 
speed dictated by an audio signal. Every minute the speed increases. Every change in speed 
will be indicated by a triple audio signal (triple bleep).
The test starts with a triple bleep [start the stopwatch: Timing starts at the first triple beep, 
when the patient starts walking at the slowest speed (level 1)]; the patient starts at one of the 
cones. Thereafter, the CD emits a single bleep at regular intervals; the patient is advised to 
walk at a steady pace, aiming to turn around at the cone at the opposite end of the course when 
he/she hears the signal (single bleep). When the signal sounds the patient should be turning 
around the cone and proceed back down the course.

Each minute the speed of walking is increased by a small increment; a change of speed to the 
next level is indicated by a triple bleep from the CD, and the operator asks the patient to 
increase his speed slightly. There are 12 levels of speed beginning at 0.50 m/s and ending at 
2.37m/s.
To help the patient to establish the routine of the test, the operator walks alongside the patient 
for the first minute (3 shuttles the first minute). When the patient reaches the cone before the 
signal, he/she is instructed to wait until the signal indicates that he/she can proceed. When the 
patient did not reach the cone within 0.5 meter when the signal sounds, the operator asks the 
patient to increase his speed (“You’re not going fast enough; try to make up the speed this 
time”); if the patient fails to keep up the required pace after repeated warnings and 
encouragements, the test ends.
During the test patients should be encouraged (in a standardized way) to keep the pace or to 
catch up when lagging behind.
Patients will be asked to rate the intensity of breathing and leg discomfort using the MBS-S
(see section 10.5) prior to exercise, every two minutes during exercise and at end-exercise.
This is a maximal test. The patient will exercise until:
•
limited by symptoms (i.e., is unwilling to continue exercising because of the discomfort 
associated with the exercise); OR
•
unable to maintain the walking pace emitted by the CD (even with repeated 
encouragement): patient is not within 0.5 meter from the cone at the beep and not able to 
catch up within 3 shuttles; OR
•
unable to continue safely (in the opinion of the supervising technician or physician). 
The duration of exercise will be recorded using a stopwatch (in minutes and seconds). 
At the end of exercise, after having taken the peak blood pressure measurement, the patient can 
rest on the chair, or walk around if he/she prefers.
At end-exercise the following parameters will be recorded immediately: oxygen saturation, 
(SpO2%), blood pressure, heart rate and rating of the intensity of breathing discomfort and leg 
discomfort (MBS-S), followed by the MDP and locus of symptom limitation VAS (Appendix 
10.6). Repeat blood pressure, heart rate and SpO2% measurements will be taken five minutes
later to assess recovery rate.
The number of completed shuttles is recorded on the ISWT recording sheet. One shuttle is 10 
meters, the distance covered between two bleeps. The last shuttle is considered complete if at 
least ¾ of the distance was covered when the patient stopped the test. The total distance 
covered is calculated (distance in meters = number of complete shuttles x10).

The patient should remain in a clinical area for at least 15 minutes following an uncomplicated 
test or for at least 30 minutes after resolution of any symptoms. 
Note that patients who complete level 12 will not be eligible to continue in the study (exclusion 
criterion 22).
Constant Speed Shuttle Test
10.4.2.2
The following procedure is to be followed for the 3min CSST conducted throughout the study.
Determination of speed for the 3min CSST:
The methodology for the execution of the 3min CSST is described by 
group [P12-12739]. Based on the findings from the initial study, the current protocol was 
designed as described.
At visit 2, a test consisting of one bout of three minutes of walking at the initial speed of 4.0 
km/h is completed. Thirty minutes after this first test, a second test will be performed at a 
speed of either 5.0 or 3.25 km/h. 
The second walking rate will be determined by the ability to complete the full 3 minutes of the 
test at 4.0 km/h. If a patient cannot complete the first test, then the second speed will be 
stepped down to 3.25 km/h. If a patient is able to complete the full 3 minutes in the first test, 
then the second speed will be increased to 5.0 km/h. Patients will be asked to perform up to 
three tests at different speeds in order to determine, amongst the 3 different speeds, the highest 
speed that meet the following parameters:
•
can be sustained for the entire 3 minutes, and
•
achieves a BORG breathlessness rating of ≥4.
In doing so, the objective is to induce a level of dyspnea that is sufficiently high to be 
amenable to therapy.
Depending on the patient’s ability to complete 3 minutes OR achieve a BORG breathlessness 
rating ≥4 then the speed can be further adjusted up to 6.0 km/h or down to 2.5 km/h to achieve 
these requirements. Please consult the Manual of Procedures for more detailed instructions for 
speed selection. 
An appropriate speed will be determined based on patients’ ability to complete the entire 3 
minutes of a speed and achieve a BORG rating ≥4.  If these 2 parameters are not fulfilled at 
any speed, the patient will be considered a screen failure.

These speeds are selected based on previous work by 
’ group showing that these 
were sufficiently demanding to induce measurable levels of dyspnea and that most moderate to 
severe patients with COPD are able to complete the test for the desired duration [R15-4319].
Patients will be directed to follow the audio signal for the entire 3 minutes of the test. They will 
be instructed to walk/jog/run around the two cones set-up in the hospital hallway pacing their 
walk/jog/run in a way not to wait at the cones for the following audio signal.
The values for the completed 3min CSST tests will be recorded in the eCRF, and will be used 
for all subsequent 3min CSSTs: the training 3min CSST (visit 3) and for the subsequent 3min 
CSSTs conducted.
No adjustments to the speed selected at visit 2 are permitted throughout the trial.
Physiological parameters will be taken during the 3min CSSTs using mobile cardiopulmonary 
exercise equipment.

MODIFIED BORG SCALE (MBS-S)
10.5
[R14-0975]
PATIENT INSTRUCTIONS
We will be using the BORG Scale to help us understand the intensity or severity of your breathing
discomfort and the intensity or severity of your leg discomfort. We will ask you to use this scale to rate
the intensity of your breathing discomfort and your leg discomfort before, during, and after your 
exercise test.
Please review the scale to see the various levels from which you can choose. 
For breathing discomfort:
The top of the scale, “0 or nothing at all,” means no breathing discomfort at all. 
The bottom of the scale, “10 or maximal,” means the most severe breathing discomfort that you have 
ever experienced or could imagine experiencing.  
For leg discomfort:
The top of the scale, “0 or nothing at all,” means no leg discomfort at all.
The bottom of the scale, “10 or maximal,” means the most severe leg discomfort that you have ever 
experienced or could imagine experiencing.  
When we ask you to rate the intensity of your breathing discomfort and your leg discomfort, please 
place the tip of your finger on the number that best describes the intensity that you are experiencing at 
that moment. You may also place a finger between 2 numbers if that better describes the intensity of 
your breathing discomfort or your leg discomfort.
Please let us know if you have any questions before we begin.

Instructions for the Modified BORG Scale
Prior to the start of exercise test, each subject will be told that they will be asked to rate the
intensity of sensations at rest, during exercise and at end-exercise.  The sensations will be 
described to the subject as: 
•
Discomfort with your breathing
Use of the BORG Scale to rate these sensations will be explained to the subject. While showing 
the scale to the subject, the study coordinator or blinded tester will explain that the subject 
should relate the wording on the BORG Scale to the level of the sensation that he / she is 
experiencing, and then place the end of a finger on a number that best describes the intensity of 
the sensation - explain that placing a finger between 2 numbers is allowed. (BORG Scale 
numbers will be recorded to the nearest 0.5 units). 
The study coordinator or blinded tester will anchor the endpoints of the scale for both sensations. 
The study coordinator or blinded tester will explain that for the sensation of “discomfort with 
your breathing”, “0 or nothing at all” corresponds to “no discomfort with your breathing” and 
“10 or maximal” corresponds to the “most severe discomfort with your breathing that you have 
ever experienced or could imagine experiencing”. 
 
Subjects are to be given no further information about these sensations. If a subject requests 
further clarification, he/she will be told to use his/her own individual interpretation as to the 
meaning of the sensory descriptors. This will ensure that the sensory descriptors are presented 
to each subject in a standard format.

INSPIRATORY CAPACITY AND FRC
10.7
In this trial FRC measurements will be done at visit 1 in the body box to determine eligibility.
FRC predicted equations according to Crapo [R99-0401]:
Males: Y=0.0472(Ht in cm) + 0.009 (Age) – 5.29
Females: Y=0.036(Ht in cm) + 0.0031(Age) - 3.182
Inspiratory Capacity measurements:
IC measurements will be performed during exercise testing as follows: 

ISWT - at rest, during exercise and at the end of exercise 

3min CSSTs – at rest and at the end of exercise
IC measurements will be taken using mobile cardiopulmonary exercise equipment capable of 
measuring IC during the shuttle tests.
To supplement the information on IC manoeuvres in this chapter, a manual of procedures has 
been developed. More detailed information on IC measurements, calculations and post-test 
corrections etc. can be found in this manual which is filled in the ISF.
Resting IC
At each required visit, IC maneuvers will first be fully explained to the patient and then practiced 
at rest to confirm proper technique. Patients will be given a few breaths warning before an IC 
maneuver, a prompt for the maneuver (i.e., “At the end of the next normal breath out, take a deep 
breath all the way IN”), and then strong verbal encouragement to make a maximal effort before 
relaxing.
The patient will be performing these IC maneuvers in the “Rest phase” of the exercise test
using mobile cardiopulmonary exercise equipment.  The patient should breathe quietly for a 
few breaths to achieve stable end expiratory lung volume (EELV) and then perform the 
inspiratory maneuver from EELV to TLC. The patient can be taken off the mouthpiece 
between maneuvers. The patient should return to stable EELV prior to preforming the next 
maneuver. At least three reproducible IC measurements should be obtained (i.e., within ± 10% 
or ± 100 mL whichever is larger) with a maximum of 5 measurements to be performed. The 
resting IC should be recorded as the mean of the two highest acceptable efforts.
Exercise IC for the ISWT
These IC maneuvers will be carried in a manner similar to that at rest. For the end-exercise IC 
maneuver specifically, the BORG scale intensity of breathing discomfort and leg discomfort 
ratings should precede IC maneuver by at least 5 breaths to avoid interfering with pre-IC 
breathing patterns.

End exercise IC 
An IC maneuver should be performed directly after having performed the BORG scale 
measurements after end-exercise (i.e., first 15 seconds of recovery) and used as the “end-
exercise” measurement. However, for the ISWT, if during the exercise test, a scheduled IC 
maneuver is performed within 30 seconds prior to the end of exercise, the final IC maneuver 
during exercise will be considered as the “end-exercise” measurement.
Analysis / acceptability of IC maneuvers 
If the effort appears sub-maximal or if anticipatory changes in breathing pattern occur 
immediately preceding a maneuver, then the IC should not be accepted unless it can be corrected 
post-test.
