Trial rationale
Despite evidence supporting the efficacy of tiotropium + olodaterol
Respimat® in a broad COPD population, data demonstrating the 
effectiveness of tiotropium + olodaterol Respimat® on pulmonary 
function in individuals stratified by optimal and sub-optimal peak 
inspiratory flow rate (PIFR) is lacking.
Trial objective
This study is designed to demonstrate the efficacy of inhaled 
tiotropium + olodaterol 5ug/5ug via Respimat® on lung function in 
patients with moderate to severe COPD with optimal and sub-optimal 
PIFR.
Trial endpoints
Primary endpoint:
Change from baseline in FEV1 AUC0-3h at week 4.
Key secondary endpoint:
Change from baseline in trough FEV1 at week 4.
Trial design
Randomized, double blind, multi-center, parallel group, placebo-
controlled trial stratified by PIFR optimal (≥60L/min) and sub-
optimal (<60L/min) group.
Total number of patients
randomized
Approximately 200
Number of patients on 
each treatment
100
Diagnosis
Patients diagnosed with moderate to severe COPD (GOLD 2 - 3), 
based on Global Initiative for Chronic Lung Disease guidelines.
Main inclusion and 
exclusion criteria
Inclusion Criteria:
1. Signed and dated written informed consent in accordance with

mixed effects model repeated measures (MMRM) approach because 
data are available at an additional visit. The MMRM model will 
include the fixed, categorical effect of treatment at each visit, and the 
fixed continuous effect of baseline at each visit. The primary endpoint 
will be compared across treatment groups in PIFR subgroups (first 
optimal and then sub-optimal). Then the key secondary endpoint will 
be compared across treatment groups in the PIFR subgroups in the 
same order.The entire hierarchical hypothesis testing strategy for 
tiotropium + olodaterol FDC (5µg/5µg) versus placebo in PIFR 
subgroups will be protected at an overall two-sided 0.05 type I error 
rate.

1.
The interval between visits 1 and 2 (screening period) can be extended for up to 2 weeks for 
administrative reasons (section 6.2.1).
2.
All patients discontinued permanently during the treatment period, should complete EOT visit and the 
procedures associated with EOT visit.  Follow-up visit (via telephone) for discontinued patients should 
be scheduled 3 weeks after the last dose of trial medication.
3.
All patients must sign an informed consent consistent with ICH-GCP guidelines prior to participation 
in the trial, which includes medication washout and restrictions.  Medication washout is not required 
for screening visit in this study.  Patients participating in the optional body plethysmography procedure 
must sign a separate consent.
4.
Please refer to sections 5.2.1 and 5.2.2 for guidance on physical examination and vital signs.

5.
Patient should be registered in IRT as an enrolled patient on the day of consent.  At visit 2, patient will 
be randomized and stratified via the IRT.  Please refer IRT user manual for details on other transactions 
with IRT.
6.
Medication washout criteria should be checked before initiating any visit procedures.  If patient does 
not meet medication washout requirements, visit should be rescheduled.
7.
Pulmonary function tests: visit 1 measurements are to determine patient eligibility.  Schedule for serial 
spirometry measurements at visits 2 and 4 are provided in the table below the footnotes.  At visit 3, 
only trough FEV1 measurements are done.  At visit 2, the PFTs should begin between 07: 00 a.m. and 
10:00 a.m.  At visits 3 and 4, PFTs should begin within ± 30 minutes of the time it started at visit 2.  
Pulmonary function tests must be completed before plethysmography in patients participating in the 
optional trial procedure.
8.
Plethysmography to be done only at selected sites on selected patients.  Sites should have their own 
body plethysmography equipment.  At the screening visit, an assessment will be completed to see if the 
patient can perform technically acceptable body plethysmography tests.
9.
Fasting is not required for safety labs.
10. eGFR will be derived from serum creatinine values, age, sex and race based on the CKD-EPIcr 
equation [R12-1392].
11. Women of child-bearing potential: serum pregnancy test is to be completed at visit 1.  Urine pregnancy 
test (dipstick) is to be completed at visits 2, 3, and 4 (see section 5.2.3)
12. If the interval between screening and randomization visits is less than one week, and the ECG 
recording obtained at the screening visit is normal, ECG will not be repeated at the randomization visit.
13.
must be dispensed at the screening visit along with the paper diary.  Patient must 
be trained on how the PIFR measurements will be performed and recorded in the diary
(see section 6.1).  At visits 2 and 3, the diary should be reviewed, and additional training provided to 
the patient if necessary.
14. Patients should be coached on how PIFR measurements are done and recorded in the patient’s diary.  
Patients should be reminded to bring the diary to all future clinic visits.
15. PIFR measurements using med/low and high resistance in the 
will be collected in 
the clinic at visits 2, 3, and 4.  Measurements made at the screening visit are for training purpose only.  
For more details, see section 6.1.
16. Rescue medication (salbutamol, also known as albuterol) must be dispensed at the screening visit.  
Patient should bring the inhaler back to the clinic at all future visits.  Investigator should ensure that 
patient has adequate supply of rescue medication until the next clinic visit.  Salbutamol will not be 
dispensed at EOT.  Supply of salbutamol will not be managed via IRT.
17. At the randomization visit, patient must receive adequate training on using the Respimat® device
(see section 6.2.2).  If necessary, patient must be trained again at visit 3. Study sites will have separate 
inhalers as training device.
18. PIFR measurement with med/low resistance will be used for stratification of optimal and sub-optimal 
groups.  Measurements will be made in triplicate and the highest value will be used for stratification.  
PIFR measurements made at the screening visit must not be used for stratification.
19. For unscheduled re-supply of study drug, refer to IRT user manual.
20. Please refer to section 4.3 for treatment compliance.
21. Follow-up visit will be completed by telephone.  Investigator will have the discretion to bring the 
patient to do an in-clinic follow-up visit if any safety issues are identified at EOT.
(*****) After the Follow-up visit (=individual patient’s end of the trial) the investigator should report 
only any cancers of new histology and exacerbations of existing cancer and trial treatment related 
SAEs of which the investigator may become aware of and only via the BI SAE form, please see section 
5.2.6.2.1.

INTRODUCTION
1.1
MEDICAL BACKGROUND
The complementary modes of action of tiotropium + olodaterol have previously been 
demonstrated in phase II clinical trials and during the Phase IIIa program that led to the 
registration of tiotropium + olodaterol combination in the European Union (EU), the United 
States and several other countries (P15-03349).
In the Phase III program the additional benefits of the tiotropium + olodaterol fixed dose 
combination (FDC) over its mono-components and placebo have been assessed on lung
function, quality of life (St. George's Respiratory Questionnaire -SGRQ), dyspnea (Transition 
Dyspnea Index-TDI), moderate and severe chronic obstructive pulmonary disease (COPD)
exacerbations and exercise endurance time (P15-03349).
Inhaled bronchodilators are a mainstay of therapy for COPD, bronchodilator therapy can be 
delivered via several modalities including dry powder inhalers (DPIs), soft mist inhalers 
(SMIs), nebulized solutions, and pressurized metered dose inhalers (pMDIs).  Drug delivery 
via inhalation devices is dependent on the inspiratory flow rate generated by the patient.  It is 
now widely recognised that a successful treatment outcome in COPD depends as much on the 
inhaler device as it does on the drug (P06-04748).
The majority of patients with COPD present with moderate to severe airflow obstruction at 
time of diagnosis.  In COPD patients expiratory airflow limitation is typically accompanied 
by decreased inspiratory capacity, hyperinflation and respiratory muscles impairment, which 
combined, result in reduced inspiratory flow rates, which could diminish lower airway 
deposition of the drug (P06-04750).
Achieving the correct inhalation flow from any inhalation device is critical in order for the 
patient to achieve therapeutic benefit from the inhaled drug. Patients with COPD may use 
sub-optimal inhalation flows as they may not have the energy generated by their inspired 
breath to achieve the effective inhalation flows that are required for some devices (R15-5362). 
However, inspiratory flow rates or the patient´s ability to perform the required inhalation 
maneuver are rarely checked in clinical practice before selecting an inhaler/treatment, 
increasing the risk of patients not receiving the full clinical benefits of the treatment 
prescribed.
The Respimat® Soft MistTM Inhaler actively delivers a metered dose of medication, with 
minimal inspiratory effort from the patient,  as a fine slow moving, long lasting mist, with a 
high fine particle fraction, resulting in a high lung deposition and lower oropharyngeal 
deposition (P12-01215, P05-10480, P06-10775). In vitro data has demonstrated that
Respimat® Soft MistTM delivers high lung deposition at low modelled flow rates and across 
disease severities, and requires only a very low inspiratory effort (P17-06338).
Dry powder inhalers have higher internal resistance than that of SMIs and pMDIs; as a result, 
the inspiratory force necessary to overcome the internal resistance of DPIs, to optimally

release the medication from the inhaler and deliver into the airways, is greater than what is 
required for pMDIs and SMIs. The 
.) 
has been introduced as a simple, low cost method of measuring an individual’s inspiratory 
flow rate.  It is generally accepted that a PIFR of 60 L/Min (optimal PIFR) is required for 
adequate drug delivery by a DPI with medium internal resistance.  In previous studies of 
small cohorts, approximately 30-50% of patients are unable to generate the targeted PIFR of 
60 L/Min as measured by
with medium or low resistance.  There is also 
evidence demonstrating that, at the time of discharge from an acute care hospital for 
treatment of a COPD-related hospitalization, one third of patients had a sub-optimal PIFR 
with medium or low resistance measured by 
.  It has been demonstrated 
that sub-optimal PIFR is a predictor of 90-day readmission for COPD, days to all-cause 
readmissions and days to COPD readmission. Multivariate analysis has demonstrated that 
age, gender, height, forced vital capacity (FVC) % predicted and inspiratory capacity (IC) % 
predicted are independent predictors of sub-optimal PIFR. This evidence highlights the 
importance of inspiratory flow rate in the effective delivery of inhaled therapies; yet, the 
evidence for the benefits provided by currently available inhaled treatments for COPD 
according to the inspiratory flow rates generated by patients, is scarce.  
1.2
DRUG PROFILE
Tiotropium + olodaterol combination
Tiotropium + olodaterol FDC is an aqueous solution of tiotropium + olodaterol contained in a 
cartridge. It is administered by using the Respimat® inhaler. One cartridge is used per 
inhaler, which is inserted into the device prior to first use.
In the pivotal studies (c01735218-03, c01735249-03), tiotropium + olodaterol FDC showed 
statistically significant improvements in Forced Expiratory Volume in first 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 (SGRQ) and dyspnea experienced during everyday activities [Transition 
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 
which exceeded the Minimal Clinically Important Difference.
Treatment with tiotropium + olodaterol FDC also resulted in reductions in both daytime and 
night time rescue bronchodilator use compared to the mono-components. The
bronchodilatory profile of the combination was confirmed in a supportive 6-week study 
(c02093555-02), in which the mean FEV1 improvements over 24 hours were superior to the 
monocomponents, with improvements in FVC, inspiratory capacity (IC), and functional 
residual capacity (FRC), supporting the results for FEV1. 
Tiotropium + olodaterol FDC was shown to be safe and well tolerated over 1 year in a 
moderate to very severe COPD population. The overall incidence of adverse events (AEs), 
serious adverse events (SAEs), fatal AEs, frequencies for cardiac events and major adverse

cardiovascular event 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.
Based on these observations, marketing authorization for tiotropium + olodaterol (5μg /5μg) 
FDC (total daily dose) has been granted in US, Canada, Australia, in all European countries 
within the decentralized procedure as well as in a number of other countries worldwide.
For a more detailed description of the drug profile refer to the current Summary of Product 
Characteristics (SmPC) for Spiolto® or the United States Prescribing Information (USPI) for 
Stiolto® which are included in the Investigator Site File (ISF).
Boehringer Ingelheim’s Respimat® inhaler will be used for administration of study drug. The 
medication is provided as an aqueous solution in a cartridge, which is inserted into the device 
prior to first use. A propellant-free device, the Respimat® inhaler generates a soft mist which 
is released over a period of approximately 1.5 seconds. The fraction of fine particles 
accessible to the lungs and airways is very high compared with many metered dose aerosols 
or dry powder devices. The use of the Respimat® inhaler has been shown to be safe with 
regards to paradoxical bronchoconstriction during chronic use in patients with COPD 
(P05-08465). The Residual Effect Period (REP) of tiotropium + olodaterol FDC is 21 days.
Salbutamol used as rescue medication in this trial is a short-acting, selective beta2-adrenergic 
receptor agonist used in the treatment of asthma and COPD.  Salbutamol is a bronchodilator 
that opens up the airways affected by bronchoconstriction, therefore relieving the wheezing 
and shortness of breath.  Salbutamol can be used as a fast-acting rescue medication that 
provides quick relief..
1.3
RATIONALE FOR PERFORMING THE TRIAL
Despite evidence supporting the efficacy of tiotropium + olodaterol Respimat® (R19-2073) in 
a broad COPD population, data demonstrating the effectiveness of tiotropium + olodaterol 
Respimat® on pulmonary function (trough FEV1, FEV1 AUC) in individuals stratified by 
optimal and sub-optimal PIFR is lacking.  Spirometry data from the tiotropium + olodaterol 
clinical development program include mostly lung function and volumes from an expiratory 
maneuver, which does not allow to measure PIFR; when an inspiratory maneuver has been 
performed, it is performed against no resistance from the spirometer, which makes it not 
possible to measure the PIFR simulating the resistance of an inhaler.  Furthermore, since the 
measurement of PIFR is not routinely performed in daily clinical practice, the effectiveness 
of tiotropium + olodaterol Respimat® according to the patients´ PIFR from real world use has 
not been assessed.
Data from this study may facilitate the clinician´s decision when choosing a treatment and 
delivery system, as it could provide certainty that the treatment selected will be effectively 
delivered independently of the patient ability to generate sufficient energy through the 
inhalation effort.

BENEFIT - RISK ASSESSMENT
1.4.1
Benefits
Clinical trials conducted to date have shown tiotropium + olodaterol (5μg/5μg) fixed dose 
combination to be a safe, well tolerated and efficacious combination therapy according to 
treatment guidelines in a moderate to very severe COPD population.  The OTEMTO studies, 
demonstrated improvements in lung function with tiotropium + olodaterol over placebo and 
tiotropium after 12 weeks of treatment in patients with moderate to severe COPD 
(P15-08379), the population to be included in this study
1.4.2
Risks
Potential risks associated with administration of the combination of tiotropium + olodaterol 
include the listed (expected) adverse events for tiotropium / olodaterol (5μg/5μg) fixed dose 
combination as described in the USPI/EU SmPC.
Women of childbearing potential may be included in clinical trials for tiotropium + olodaterol
(5μg/5μg) fixed dose combination provided appropriate precautions are taken to minimize the 
probability of becoming pregnant.  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.
A placebo group is included in the trial to provide an appropriate control for the assessment 
of the effects of the tiotropium + olodaterol FDC on lung function (FEV1) according to the 
inspiratory flow rate (PIFR) the patients can generate.  In order to minimize the risk for the 
study patients, a number of population and design measures have been put in place, namely:

The duration of the treatment period including placebo is limited to 4 weeks.

The population for this study excludes patients with very severe COPD and patients 
currently treated with inhaled corticosteroids (ICS).

Patients with a recent exacerbation (6 weeks prior to visit 1) or with a history of 
frequent exacerbations (two or more exacerbation requiring treatment with systemic 
glucocorticoids, antibiotics or both, or an exacerbation that required hospitalization 
within one year prior to visit 1) are also excluded.

The study does not include a long washout period.  In order to shorten the time of 
placebo treatment; patients will continue to receive their prescribed treatment until 
three days before randomization.

Patients will receive salbutamol as rescue medication.

Within the four-week treatment period, a study visit in the clinic has been added after 
two weeks of treatment as an opportunity for assessment of the patients’ condition by 
the investigators.
Boehringer Ingelheim will provide open-label salbutamol as rescue medication for all 
patients during the course of the trial.

1.4.3
Discussion
Tiotropium + olodaterol FDC delivered via the Respimat® device was shown to be effective 
in improving lung function, quality of life and dyspnea as well as improve exercise tolerance.  
It has also shown to be safe and well tolerated over 1 year in a moderate to very severe 
COPD population; however, there is currently no clinical data available from randomized 
controlled trials or from real world studies to demonstrate whether COPD patients can benefit 
from tiotropium + olodaterol Respimat® independently of the inspiratory flow they can 
generate.  
Data from this study will provide this evidence and therefore help in the personalization of 
treatment selection for COPD patients.  Considering a placebo arm is included in the study, 
the treatment and follow-up period has been kept short, and includes a clinic visit after two 
weeks of treatment to assess the patients’ condition.  Further measures are in place to 
minimize the risk for the study population are the exclusion of the most severe COPD 
population, the population treated with inhaled corticosteroids, those patients with a very 
recent COPD exacerbation, or with a history of frequent COPD exacerbations and at risk of 
COPD exacerbations.

DESCRIPTION OF DESIGN AND TRIAL POPULATION
3.1
OVERALL TRIAL DESIGN 
This trial is a randomized, double-blind, placebo-controlled, multicenter, parallel study 
designed to assess efficacy of tiotropium + olodaterol delivered by Respimat® on FEV1
AUC0-3h, and trough FEV1 in patients with moderate to severe COPD, stratified by optimal 
and sub-optimal PIFR.  The study will consist of a screening period of up to 2 weeks, a 
4-week randomized treatment period and a three week follow-up period.  An overview of the 
trial design is presented in Figure 3.1: 1.
Figure 3.1: 1 Trial Design
Approximately 200 patients will be randomized (1:1) to either the active arm (tiotropium + 
olodaterol, FDC) or the placebo arm. The randomization will be stratified by optimal 
(≥60 L/min) or sub-optimal (< 60 L/min) PIFR as measured with the 
set 
at med/low resistance. Each strata will be capped to a total of approximately 100 patients.  
An interactive response technology (IRT) will be used for randomization and stratification.
After signing informed consent and completing the screening visit, patients will enter a 
screening period of 3 to 14 days. During the screening period, patients will continue to 
receive their COPD maintenance treatment, except for the medication washout requirements 
required before the randomization visit (see Table 4.2.3.1: 1).  Patients will be randomized 
into the 4-week treatment period in which they will be randomly assigned to one of two 
treatments: tiotropium + olodaterol FDC or matching placebo.  The randomization visit (visit 
2) will be followed by a clinic visit in 2 weeks (visit 3) and end of treatment (EOT) visit (visit 
4) will be 4 weeks (28 days) after randomization.  A follow-up visit by telephone will be 
scheduled three weeks after the last dose of study medication.  Study procedures to be 
performed at each clinic visit are presented in the Flow Chart.  The timing of the pulmonary 
function tests with serial spirometry at baseline (visit 2) and at EOT (visit 4) is provided in
the table below the Flow Chart.
Patients will be washed out of COPD medications for approximately 72 hours before 
randomization.  Patients will be allowed to use salbutamol as rescue medication during this

washout period.  Once randomized, patients will receive either tiotropium + olodaterol FDC 
via Respimat® inhaler or matching placebo.  All patients will receive salbutamol for use as 
rescue medication, as needed, from screening visit until EOT.  At the conclusion of EOT 
visit, patients can resume taking their regular COPD medications.  At the EOT visit,
investigator should advise the patients on appropriate care during the follow-up period and 
after completion of the study.  During the follow-up period, patients will not receive study 
medication.  Rescue medication will not be dispensed at EOT visit for use during the follow-
up period.  Patients on ICS maintenance therapy (monotherapy or combination with 
bronchodilators) will not be eligible to participate in this study.
Body plethysmography measurements will be an optional trial procedure at visit 2 and will be 
done only at selected sites on selected patients.  Approximately 30 (15%) patients are 
expected to participate in this procedure.  Patients participating in this optional trial procedure 
will have to sign a separate informed consent. At the screening visit, an assessment will be 
completed to see if the patient can perform technically acceptable body plethymography 
measurements.
3.2
DISCUSSION OF TRIAL DESIGN, INCLUDING THE CHOICE OF 
CONTROL GROUP
Currently, data on the impact of PIFR on the effectiveness of treatments/inhalers available for 
COPD is not consistent or not available, and available data on existing treatments/inhalers 
cannot be extrapolated to the population of interest.  A comparison with placebo was 
considered the best approach to assess the effect of tiotropium + olodaterol FDC in this 
population.
There is no previous data or knowledge of the treatment effect of tiotropium + olodaterol on 
spirometric parameters in the two PIFR populations (< 60 L/min and ≥ 60 L/min). Therefore 
the trial will need to enroll a sufficient number of placebo patients in order to make an 
assessment of efficacy between treatment and placebo.  A 4-week treatment period is 
considered sufficient to evaluate the effects of tiotropium + olodaterol FDC in patients with 
COPD (P19-01878).
It is anticipated that with 200 patients randomized 1:1 in the trial and, a duration of 4 weeks,
there is adequate statistical power to detect an effect of the treatment vs placebo in each of 
the PIFR sub populations.
3.3
SELECTION OF TRIAL POPULATION
Recruitment of patients for this trial is competitive, i.e. screening for the trial will stop at all 
sites once a sufficient number of patients have been screened to randomize 200 patients.  
Approximately 40 study sites are expected to participate in this study.  Approximately 300 
patients are expected to be screened.  Patients in screening at the time when a decision is 
made to stop further screening will be allowed to continue and may be randomized in the 
study if eligible.

3.3.4
Withdrawal of patients from treatment or assessments
Patients may discontinue trial treatment or withdraw consent for trial participation as a whole
(“withdrawal of consent”). Please see sections 3.3.4.1 and 3.3.4.2 below.
Every effort should be made to keep the patients in the trial, if possible on treatment.  
Measures to control the withdrawal rate include careful patient selection, appropriate 
explanation of the trial requirements and procedures prior to trial enrollment, as well as the
explanation of the procedures if the patient withdraws from the trial.  The decision to 
discontinue trial treatment or withdraw consent to trial participation, and the reason must be 
documented in the patient files and electronic case report forms (eCRF).  If applicable,
consider the requirements for adverse event collection and reporting (sections 5.2.6.2.1 and 
5.2.6.2).
3.3.4.1
Discontinuation of trial treatment
An individual patient will discontinue trial treatment if:

The patient wants to discontinue trial treatment, without the need to justify the decision.

The patient has repeatedly shown to be non-compliant with important trial procedures 
and, in the opinion of both, the investigator and sponsor representative, is not willing or 
able to adhere to the trial requirements in the future.

If a patient experiences a COPD exacerbation (moderate, or severe) during the treatment 
period, patient will be discontinued from the study (section 6.2.2).

The patient needs to take concomitant medication that interferes with the investigational 
medicinal product or other trial treatment (section 4.2.3.1)

The patient can no longer receive trial treatment for medical reasons (such as surgery, 
adverse events, other diseases, or pregnancy).  In case of a temporary reason, trial 
treatment should be restarted if medically justified.
In terms of discontinuation of trial treatment, the following criteria must also be taken into 
account:

Trial treatment must be stopped immediately if a paradoxical bronchospasm or an allergic 
reaction of the immediate type occurs. 

If two or more eye symptoms (triggering or aggravation of narrow angle glaucoma, eye 
pain or discomfort, temporary blurred vision, eye halos or altered color perception 
associated with reddened eyes due to conjunctival congestion or corneal edema) occur, 
trial treatment should be discontinued and the patient should consult a specialist 
immediately. 
For safety reasons, the investigator may decide that the patient should discontinue trial 
treatment.

If new efficacy/safety information becomes available, Boehringer Ingelheim will review the
benefit-risk-assessment and, if needed, pause or discontinue the trial treatment for all patients 
or take any other appropriate action to guarantee the safety of the trial patients. 
Even if the trial treatment is discontinued, the patients remain in the trial and, given their
agreement, will undergo the procedures for early treatment discontinuation and follow-up as 
outlined in the Flow Chart and section 6.2.3. 
3.3.4.2
Withdrawal of consent to trial participation
Patients may withdraw their consent to trial participation at any time without the need to 
justify the decision.
If a patient wants to withdraw consent, the investigator should be involved in the discussion 
with the patient and explain the difference between trial treatment discontinuation and 
withdrawal of consent to trial participation, as well as explain the options for continued 
follow-up after trial treatment discontinuation, (section 3.3.4.1).
3.3.4.3
Discontinuation of the trial by the sponsor
Boehringer Ingelheim reserves the right to discontinue the trial overall or at a particular trial
site at any time for the following reasons:
1. Failure to meet expected enrollment goals overall or at a particular trial site.
2. Emergence of any efficacy/safety information invalidating the earlier positive benefit-risk 
assessment that could significantly affect the continuation of the trial.
3. Deviations from Good Clinical Practice (GCP), the trial protocol, or the contract 
impairing the appropriate conduct of the trial.
The investigator / the trial site will be reimbursed for reasonable expenses incurred in case of 
trial termination (except in case of the third reason).

4.1.3
Method of assigning patients to treatment groups
After the assessment of all inclusion and exclusion criteria, each eligible patient will be 
stratified based on PIFR (optimal vs. sub-optimal) and randomized to one of the two 
treatment arms: tiotropium + olodaterol FDC or matching placebo in a 1:1 ratio at visit 2 via
IRT using each strata. The PIFR will be measured with the 
set at 
med/low resistance.  PIFR measurements with med/low resistance will be done in triplicate 
the highest PIFR will be used for stratification.  Note that the medication number is different 
from the patient number (the latter is generated during screening via the IRT System).
4.1.4
Drug assignment and administration of doses for each patient
Dispensing trial medication
At visit 2 the IRT will assign two Respimat® kits (one for treatment and one as reserve).  At 
visit 3 the patient will bring in all treatment kits (including the reserve kits) that were 
dispensed at visit 2.  If the reserve kit dispensed at visit 2 was used by the patient, a new 
reserve kit can be dispensed at visit 3.  Each treatment kit will have a unique medication ID 
number.  Trial medication will be dispensed to the patient by the investigator or a qualified 
site staff at these visits.  The amount of trial medication dispensed will be recorded on the 
drug accountability forms.  Patients must return all Respimat® kits at visit 4 which is the end 
of treatment period
The reserve kits allow the patient the flexibility of not having to return to the clinic 
immediately to replace a lost or malfunctioning inhaler. In the event that a patient may need 
additional inhalers and cartridges due to rescheduled visits, inhaler loss or malfunction, these 
will be supplied on an ‘on demand’ basis. Dispensing of these extra inhalers will also be 
managed via the IRT.
At home, if the patient forgets to take the morning dose of trial medication, the patient can 
take the morning dose up until 12:00 midnight. After 12:00 midnight, the patient should skip 
the dose for that day and take the next dose the following morning.
Priming of the Respimat®Inhaler
Each newly assembled Respimat®Inhaler has to be primed.  Priming should not take place in 
the same room where the patient is inhaling trial medication.  The 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.
Once assembled, the shelf-life of the Respimat® Inhaler with trial medication 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.
Dispensing rescue medication
Salbutamol will be dispensed to all patients when they complete the screening visit, and are 
eligible to enter the screening period.  Patients will receive adequate supply of rescue 
medication until the end of treatment period.  Rescue medication will not be provided for the 
follow-up period.  Before using for the first time, one actuation should be released into the air 
to ensure the device is working.

4.1.5
Blinding and procedures for unblinding
4.1.5.1
Blinding
Patients, investigators, and everyone involved in trial conduct or analysis or with any other
interest in this double-blind trial will remain blinded with regard to the randomized treatment 
assignments until after database lock.  The access to the randomization code will be kept 
restricted until its release for analysis.
4.1.5.2
Unblinding and breaking the code
Emergency unblinding will be available to the investigator via IRT.  It must only be used in
an emergency situation when the identity of the trial drug must be known to the investigator
in order to provide appropriate medical treatment or otherwise ensure safety of trial
participants. The reason for unblinding must be documented in the source documents and/or 
appropriate eCRF page.
In case the automated unblinding option via the IRT system is malfunctioning, the IRT 
service provider can be contacted (24 hours a day coverage) and the treatment allocation can 
be obtained.  IRT support has direct access to the database and the treatment information can 
be manually obtained. Details about this process will be included in the ISF. 
Due to the requirements to report Suspected Unexpected Serious Adverse Reactions 
(SUSARs), it may be necessary for a representative from Boehringer Ingelheim (BI)
Pharmacovigilance group to access the randomization code for individual patients during trial
conduct.  The access to the code will only be given to authorized pharmacovigilance
representatives for processing in the pharmacovigilance database system and not be shared 
further. 
4.1.6
Packaging, labelling, and re-supply
The investigational medicinal products will be provided by BI.  They will be packaged and 
labelled in accordance with the principles of Good Manufacturing Practice. Re-supply to the
sites will be managed via an IRT system, which will also monitor expiry dates of supplies 
available at the sites.  For details of packaging and the description of the label, refer to the 
ISF.
4.1.7
Storage conditions
Drug supplies will be kept in their original packaging and in a secure limited access storage 
area according to the recommended storage conditions on the medication label. A
temperature log must be maintained for documentation. If the storage conditions are found to 
be outside the specified range, the Clinical Research Associate (CRA), as provided in the list 
of contacts in the ISF, must be contacted immediately.
Further details are provided in the “storage conditions for trial medications” document and on 
the country-specific labels, a sample of which will be part of the ISF.

Investigational drugs are not allowed to be used outside the context of this protocol. They 
must not be forwarded to other investigators or clinics. Patients should be instructed to return 
unused investigational drug.
The investigator or designee must maintain records of the product’s delivery to the trial site, 
the inventory at the site, the use by each patient, and the return to the sponsor or warehouse / 
drug distribution center or alternative disposal of unused products. If applicable, the sponsor 
or warehouse / drug distribution center will maintain records of the disposal. 
These records will include dates, quantities, batch / serial numbers, expiry (‘use- by’) dates, 
and the unique code numbers assigned to the investigational medicinal product and trial
patients. The investigator or designee will maintain records that document adequately that the 
patients were provided the doses specified by the Clinical Trial Protocol, and reconcile all 
investigational medicinal products received from the sponsor. At the time of return to the 
sponsor or appointed Contract Research Organization (CRO), the investigator or designee 
must verify that all unused or partially used drug supplies have been returned by the clinical 
trial patient and that no remaining supplies are in the investigator’s possession.
4.2
OTHER TREATMENTS, EMERGENCY PROCEDURES, 
RESTRICTIONS
4.2.1
Rescue medication
Administration of rescue medication can occur at any point during the trial as deemed 
necessary by the patient or the investigator.  Open label salbutamol (also known as albuterol) 
will be provided as rescue medication by the sponsor.  Only the salbutamol provided by the 
sponsor should be used during the screening and treatment periods.  Patient should return all 
rescue medication (used and unused) to the study site at visit 4.

ice-cold beverages are not allowed for at least 2 hours prior to and during the 
pulmonary function testing at clinic visits.  Decaffeinated beverages are acceptable.
•
Smoking should be discouraged for the 12 hours prior to pulmonary function testing 
and throughout the test day and will not be permitted in the 30-minute period prior 
to spirometry.
4.2.3.3
Contraception requirements
WOCBP (for the definition refer to section 3.3.3) who is a trial participant will be required to 
use an acceptable method of birth control throughout the trial, and for a period of at least 21
days after last trial drug intake.
WOCBP who is a trial participant must use a highly effective method of birth control per ICH 
M3 (R2) that results in a low failure rate of less than 1% per year when used consistently and 
correctly if their sexual partner is a man able to father a child.

Or
Patients must abstain from male-female sex. This is defined as being in line with the 
preferred and usual lifestyle of the patient. Periodic abstinence e.g. calendar, ovulation, 
symptothermal, post-ovulation methods, declaration of abstinence for the duration of 
exposure to study drug; and withdrawal are not acceptable.
4.3
TREATMENT COMPLIANCE
Patients are requested to bring all remaining trial medication including empty package 
material with them when attending visits 3 and 4. Trial medication adherence should be 
reviewed by the investigator and reported in the eCRF.
Estimating compliance to trial medication
Knowing the time interval between clinic visits, it is possible to calculate the number of puffs
that should have been administered by the patient. The Respimat® Inhaler contains 60 
actuations (30 daily doses). The dose indicator shows approximately how much medication is 
left. The dose indicator scale is divided into 4 quarters. One quarter used accounts for 7 days 
of treatment (14 actuations). When the pointer enters the red area of the scale, there is 
approximately medication for 7 days (14 actuations left).  Once the dose indicator has 
reached the end of the red scale (i.e. all 30 daily doses have been used) the Respimat® inhaler 
is empty.  Patient compliance should be estimated using the dose indicator.
The acceptable medication compliance should have an overall value in the range 80% to 
120%. If the compliance is outside this range, patient needs to be re-trained.
Randomized patients should not be discontinued for lack of medication compliance without
prior discussion with the sponsor.

ASSESSMENTS
5.1
ASSESSMENT OF EFFICACY
This study is designed to demonstrate the efficacy of inhaled tiotropium + olodaterol 5µg/5µg 
via Respimat® on lung function in patients with moderate to severe COPD with optimal 
(≥60 L/min) and a sub-optimal (<60 L/min) PIFR.
5.1.1
Pulmonary function testing
 spirometers will be provided to sites for the on-site spirometry 
measurements.  The spirometers and their use, including daily calibration on test days, must 
meet American Thoracic Society (ATS) and European Respiratory Society (ERS) criteria
(P05-12782). Spirometry will be conducted with the patient in a seated position, and it is 
preferable that the same trained individual performs the PFTs 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 blows meeting the ATS criteria (with a maximum of five attempts). The highest 
FEV1 and FVC will be selected regardless of whether they come from different spirometric 
maneuvers or from the same maneuver. The 24-hour clock time of the first maneuver for each 
PFT time point will be recorded. 
The clock time of the start and end of inhalation procedure of trial medication will be 
captured by the 
 spirometer.
At the screening visit, pulmonary function tests will be performed to determine patient 
eligibility (inclusion criteria 3, section 3.3.2). At visit 2, the PFTs should begin between 
07: 00 a.m. and 10:00 a.m.  At visits 3 and 4, PFTs should begin within ± 30 minutes of the 
time it started at visit 2.  At visits 2 and 4, PFTs will be measured up to 3 hours with serial 
spirometry (specified time points are provided in the Flow Chart).  At visit 3, only trough
FEV1 measurements are performed.
5.1.2
Peak inspiratory flow rate measurements
The 
 a hand held device to measure PIFR will be provided to each 
patient.  At the randomization visit the optimal and sub-optimal groups will be determined 
based on the PIFR measurements completed at the clinic at visit 2. PIFR values obtained 
from med/low resistance level will be used for stratifying the patients via IRT. Additional 
PIFR measurements will also be done in the clinic during visits 2, 3, and 4.  Measurements 
will be made in triplicate using med/low and high resistance and the highest value for each 
resistance setting will be recorded.  In addition, patients will use the
at 
home to collect the PIFR data and record the measurements in the patient diary.  Additional 
guidance on PIFR measurements in the clinic and at home are presented in section 6.1.

The lab reports from central laboratory will be made available to the investigator.  It is the 
responsibility of the investigator to evaluate the laboratory reports. Clinically relevant 
abnormal findings as judged by the investigator will be reported as adverse events 
(section 5.2.6).
The central laboratory will transfer the results of the analysis to the sponsor.

Electrocardiogram
The 12-lead electrocardiogram (ECG) must be administered by a qualified technologist and 
results will be recorded as scheduled in the Flow Chart.  The investigator or a designee will 
evaluate whether the ECG is normal or abnormal and assess clinical relevance.  ECGs may be 
repeated for quality reasons.  Additional ECGs may be recorded for safety reasons. Dated and 
signed printouts of ECG with findings should be documented in patient’s medical record.
Clinically relevant abnormal findings will be reported either as baseline condition (if 
identified at the screening visit) or otherwise as AEs and will be followed up and/or treated as 
medically appropriate.

Assessment of adverse events
5.2.6.1
Definitions of AEs 
5.2.6.1.1
Adverse event
An AE is defined as any untoward medical occurrence in a patient or clinical investigation 
subject administered a medicinal 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), symptom, or disease temporally associated with the use of a medicinal 
product, whether or not considered related to the medicinal product.
The following should also be recorded as an AE in the eCRF and BI 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 exist prior to trial inclusion, they will be considered as baseline 
conditions and should be collected in the eCRF.

5.2.6.1.2
Serious adverse event
A SAE is defined as any AE, which fulfils at least one of the following criteria:
-
results in death,
-
is life-threatening, which refers to an event in which the patient was at risk of death at 
the time of the event; it does not refer to an event that hypothetically might have 
caused death if more severe,
-
requires inpatient hospitalization or prolongation of existing hospitalization
-
results in persistent or significant disability or incapacity,
-
is a congenital anomaly / birth defect,
-
is deemed serious for any other reason if it is an important medical event when based 
on appropriate medical judgement which may jeopardize the patient and may require 
medical or surgical intervention to prevent one of the other outcomes listed in the 
above definitions. 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 hospitalization or development of dependency or abuse. 
5.2.6.1.3
AEs considered “Always Serious”
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 
defined above.
The latest list of “Always Serious AEs” can be found in the electronic data capture (eDC)
system. A copy of the latest list of “Always Serious AEs” will be provided upon request. 
These events should always be reported as SAEs as described in section 5.2.6.2.
Cancers of new histology and exacerbations of existing cancer must be classified as a serious 
event regardless of the time since discontinuation of the drug and must be reported as 
described in 5.2.6.2, subsections “AE Collection” and “AE reporting to sponsor and 
timelines”.
5.2.6.1.4
Adverse events of special interest
No adverse events of special interest have been defined for this trial.
5.2.6.1.5
Intensity (severity) of AEs
The intensity (severity) of the AE should be judged based on the following:
Mild:
Awareness of sign(s) or symptom(s) that is/are easily tolerated.
Moderate:
Sufficient discomfort to cause interference with usual activity.
Severe:
Incapacitating or causing inability to work or to perform usual activities.

5.2.6.1.6
Causal relationship of AEs
Medical judgement should be used to determine whether there is a reasonable possibility of a 
causal relationship between the adverse event and the given study treatment, 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. 
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 diseases, or co-medications).

The event is typically drug-related and infrequent in the general population not 
exposed to drugs (e.g. Stevens-Johnson syndrome).

An indication of dose-response (i.e. greater effect size if the dose is increased, smaller 
effect size if dose is reduced).
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-treatment 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 diseases appear to provide a more 
likely explanation for the observed event than the drug concerned).

Disappearance of the event even though the trial drug treatment continues or remains 
unchanged.
5.2.6.2
Adverse event collection and reporting
5.2.6.2.1
AE Collection
The investigator shall maintain and keep detailed records of all AEs in the patient files.
The following must be collected and documented on the appropriate eCRF(s) by the 
investigator:
•
From signing the informed consent onwards until the individual patient’s end of trial
(completion of follow-up period): 
all AEs (serious and non-serious).

•
After the individual patient’s end of trial: the investigator does not need to actively 
monitor the patient for new AEs but should only report any occurrence of cancer and trial 
treatment related SAEs of which the investigator may become aware of by any means of 
communication, e.g. phone call. Those AEs should be reported on the BI SAE form 
(section 5.2.6.2.2), but not on the eCRF.
5.2.6.2.2
AE reporting to the sponsor and timelines referring
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.
With receipt of any further information to these events, a follow-up SAE form has to be 
provided. For follow-up information the same rules and timeline apply as for initial 
information. All (S)AEs, including those persisting after individual patient’s end of trial must 
be followed up until they have resolved, have been assessed as “chronic” or “stable”, or no 
further information can be obtained.
5.2.6.2.3
Pregnancy
In rare cases, pregnancy might occur in a clinical trial. Once a patient has been enrolled in the 
clinical trial and has taken trial medication, the investigator must report any drug exposure 
during pregnancy in a trial participant immediately (within 24 hours) by means of Part A of 
the Pregnancy Monitoring Form for Studies to the sponsor.
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 Studies (Part B).  The ISF will contain the Pregnancy Monitoring Form for Studies
(Part A and 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 Studies and not the SAE form is to be completed. If 
there is an SAE associated with the pregnancy an SAE form must be completed in addition.
5.2.6.2.4
COPD Exacerbation
For the purpose of this study, a COPD exacerbation is defined as a complex of lower 
respiratory events / symptoms (increase or new onset) related to the underlying COPD, with
duration of three days or more, requiring prescription of antibiotics and/or systemic steroids
and/or hospitalization:
A complex of lower respiratory events is defined as at least two of the following:

Shortness of breath

Sputum production (volume)

Change in sputum color

“Onset of exacerbation” will be defined by the onset of first recorded symptom. The “end of
Exacerbation” will be decided by the investigator based on clinical judgment.
Exacerbations will be classified as follows:
Moderate:
patient receiving an exacerbation-related prescription of oral corticosteroids
and/ or antibiotic not requiring hospitalization.
Severe: 
COPD-related hospitalization
If a patient experiences a moderate, or severe COPD exacerbation, the patient will be

OTHER ASSESSMENTS
Body Plethysmography
Patients participating in this optional trial procedure will have to sign a separate informed 
consent.  Relative lung volumes can be measured by spirometry.  The absolute volumes of air 
in the lung can be measured by body plethysmography, where the residual volume, functional 
residual capacity, and total lung capacity can be determined.
The site’s own equipment will be used for the body plethysmography measurements. The 
volume-constant body plethysmography devices and their use, including daily calibration, 
must meet ATS/ERS criteria [R08-1121; R98-1487].  Body plethysmography will be 
conducted with the patient in a seated position and it is preferable that the same trained 
individual performs the measurements for a given patient. The body plethysmography 
measurements for assessment of FRC, total lung capacity (TLC), Residual Volume (RV) and 
IC should be performed as linked maneuver (i.e. without the patient coming off the 
mouthpiece prior to the completion of the maneuver; refer to Appendix 10.1) and to the body 
plethysmography manual in the ISF.

FRC is the sum of Expiratory Reserve Volume (ERV) and RV. This sum corresponds to the 
volume of gas present in the lung and airways at the average end-expiratory level. At least 
three technically acceptable FRC values should be obtained which agree within 5% (i.e. the 
difference between the highest and the lowest value divided by the mean is smaller or equal 
to 0.05).  If this repeatability is not accomplished, i.e. the observed deviation is larger, 
additional values should be obtained until the repeatability criterion is achieved or a 
maximum of six efforts have been performed.  If repeatability is not accomplished after the 
maximum of six efforts, no more efforts should be performed and mean FRC data will be 
regarded as acceptable, as long as they fulfill technical satisfactory quality criteria.  All 
acceptable efforts must be used for calculation of mean values of FRC (and ERV), and 
exclusion of tests for the sake of achieving repeatability is not permitted. The mean FRC 
value should be reported.  Linked to technically acceptable ERV and Inspiratory Vital 
Capacity (IVC) maneuver, mean FRC value is used for calculating the RV and TLC.
Please refer to Appendix 10.1 and to the body plethysmography manual in the ISF for further 
details in calculation of Residual Volume (RV), TLC and Inspiratory Capacity (IC).
The 24-hour clock time of the first maneuver for each body plethysmography measurement 
time-point will be recorded. Clock of 
 used is relevant for all visit 
activities and clock of body plethysmography system should be synchronized.

APPROPRIATENESS OF MEASUREMENTS
Spirometry
Pulmonary function tests are a validated and well established measurement tool for lung
function testing. Pulmonary function tests will be conducted at clinic visits using
standardized spirometry equipment. FEV1 is a standard measurement for the assessment of
lung function.
Peak inspiratory flow rate measurements
The
is a hand held device to measure PIFR.  It is commonly used in 
patients diagnosed with lung diseases like COPD and asthma.  Clinicians use this device to 
train the patients on the correct inspiratory technique to be used when inhaling the
medications from the device the patient will use to take the prescribed medication. 
is calibrated by the manufacturer to ensure accuracy.  Each patient will be 
provided an 
and a sufficient quantity of disposable mouthpieces for 
daily use.
Body Plethysmography
Pathology of COPD is not only characterized by progression in airflow limitation but also by 
progressive destruction of supporting tissues and elastin fibers of the lung. This results in 
progressive air trapping distally with increased RV, FRC and TLC and a decrease in IC.  
Hence, evaluation of static lung volumes (such as FRC, TLC, RV and IC) using body

plethysmography is a valuable tool for assessment of hyperinflation. This contributes to 
COPD symptoms like breathlessness and physical limitations while IC has the highest 
correlation with dyspnea (R11-4386; P03-10426).
Body plethysmography is technically more challenging than spirometry and requires a high
level of experience in performance. Prerequisite for study site participation in the body 
plethysmography procedures will be the availability of a volume-constant (i.e. pressure 
variable) body plethysmography device as measurements will be performed using their own 
equipment.

VISIT SCHEDULE
The trial consists of a screening period, a 4-week treatment period, followed by a 3-week
follow-up period.  The follow-up visit will be by telephone.  If visit 3 has to be rescheduled, 
visit 4 should follow the original visit date schedule.
Patients should make every attempt to complete the study.  Investigators should encourage 
patient treatment compliance and adherence to other protocol specific procedures.  Please 
refer to the Flow Chart for the trial procedures at each visit, and the time windows for the 
visits.  All deviations from the planned visit schedule will be documented.
If a patients does not meet medication washout criteria at visits 2, 3, or 4, the visit should be 
rescheduled.  The rescheduled visit should occur as soon as possible.  If visit 3 is 
rescheduled, the EOT visit (visit 4) should be scheduled on the originally planned date 
(28 days after the randomization visit).  If a patient missed visit 3, and rescheduling was not 
possible, visit 4 should be completed on the originally planned date.

DETAILS OF TRIAL PROCEDURES AT SELECTED VISITS
6.2.1
Screening period
To keep the number of screen failures as low as possible, patients should be very carefully 
selected for this trial. Therefore, investigators should make a preliminary check of major 
inclusion and exclusion criteria when considering patients for enrollment in the trial.
Patient numbers will be assigned in the IRT system and transferred to EDC, thereby creating 
the subject in EDC.  Details of any patient who is screened for the trial but is found to be 
ineligible must be entered in the enrollment log and documented in the eCRF.
No trial procedures should be performed until the patient has consented to take part in the 
trial.  Each patient will be assigned a unique patient number and enrollment will be recorded.
Baseline conditions, medical history, and eligibility criteria will be assessed at visit 1.  
Concomitant therapy and AE (if any) will be recorded.  At the conclusion of visit 1, patients 
should receive instructions on procedures to be followed during the screening period.
If the patient is expected to meet all the eligibility criteria, randomization visit (visit 2) will 
be scheduled.  Rescue medication (salbutamol) will be dispensed with instructions for use.
Patients will receive the 
to measure the PIFR at home during the 
screening period.  Patient will also receive a paper diary with instructions on how to record 
the PIFR obtained from the 
  Patients will complete the PIFR 
measurements each evening.  The PIFR measurements will be done in triplicate at the 
med/low resistance level.  Patients should be reminded that they can take breaks in between 
measurements, if needed.  Adequate training should be provided to the patients before they 
leave after the completion of the screening visit.  Patient will be asked to bring the device to 
each clinic visit.
PIFR measurements obtained at the screening visit must not be used for stratification at the 
randomization visit. PIFR value is not an eligibility criteria.  However, there is cap of 
approximately 100 patients in each strata (section 3.1).  Once the cap in a particular strata is 
reached, additional patients cannot be randomized in this strata.  Once a cap in a particular 
strata is reached, PIFR values at the screening visit will be used to determine eligibility for 
the study.  If the PIFR value obtained at the screening visit will make the patient eligible for 
the strata that is closed, patient will be screen failed at the screening visit.
Screening period may be extended by two weeks for administrative reasons after consultation 
with the Clinical Trial Manager.  Total screening period should not exceed 4 weeks 
(informed consent to randomization) unless written approval is obtained from the Clinical 
Trial Leader.  If screening period exceeds 4 weeks, the Investigator should review the 
laboratory reports from the screening visit (visit 1), and make a determination if any labs

specified in the protocol must be repeated before the randomization visit.  If deemed 
necessary, test samples should be drawn and sent to the central laboratory. 
Discontinuation during the screening period
If patients discontinue from the study during the screening period, no additional clinic visits 
are required, and they will be marked as screen failures.
If there is any indication during the screening period that the patient is not stable enough to 
complete the trial or that the patient will be non-compliant with the trial medication or 
restrictions, the patient should not be randomized, and should be screen failed.
Rescreening and retesting
Patients may be rescreened once with approval from the sponsor.  This includes patients who 
met all the inclusion criteria but were screen failed due to acute medical conditions that have 
since been resolved or those who were screen failed for administrative reasons (e.g., extended 
travel, life events).
If the investigator believes that an ineligible lab test result is the result of an error or
extenuating circumstance, then that lab test can be retested once without the patient having   
to be rescreened.
6.2.2
Treatment period
Patients who meet all the protocol criteria will be randomized at visit 2.  After randomization, 
patients will start the 4-week treatment period.  All visits during the treatment period should 
preferably be on the same day of the week.  Procedures to be completed at each visit can be 
found in the Flow Chart.
At the randomization visit (visit 2), patients will be adequately trained to use the Respimat®
inhaler.  Patients will inhale the study medication in the mornings.  Medication should be
taken approximately on the same time of the day during the 28-day treatment period.  Site 
should ensure patient has adequate supply of study medication at visit 3. Patients should be 
instructed not to take their dose of study medication at home on the day of visits 3 and 4.
Investigator should ensure that patient has adequate supply of rescue medication for the 
treatment period.  The intake of rescue medication (number of puffs) will not be collected.
PIFR measurements will be done at home (evenings) by the patient during the treatment 
period.  Measurements will be completed and readings will be recorded in the paper diary as 
described in Section 6.2.1.
At the beginning of each visit, the investigator and site personnel should ensure the 
well-being of the patient, and complete the following:
•
Any adverse events and changes in concomitant therapies will be recorded.

•
Medication washout compliance and lifestyle restrictions will be verified.
•
Before dosing with trial medication site personnel should ensure that the patient knows 
how to inhale properly from the Respimat® Inhaler.
•
At the close of each visit during treatment period, the investigator and site personnel 
should ensure that the patient is provided with all instructions for the next visit.
•
Patient will be instructed at each visit to bring all rescue medication to the site.
•
Patient will be instructed to bring the study medication (both inhalers including the 
reserve) at visits 3 and 4.
Unscheduled clinic visits may be arranged if necessary and the procedures completed during 
the unscheduled visit will depend on the circumstances under which the visit was scheduled, 
and will be at the discretion of the investigator.
After completion of the treatment phase (visit 4), all patients will enter the 3-week follow-up 
period.
Discontinuation during the treatment period
If patients discontinue from the study during the treatment period for any reason, study drug 
should be stopped, and the patient will complete the EOT visit (visit 4), and the follow-up 
visit by telephone should be scheduled 3 weeks after the last dose of study drug.  The 
investigator may schedule the follow-up visit as a clinic visit if deemed necessary.
6.2.3
Follow-up period and trial completion
The three-week follow-up period ends with a visit by telephone.  Procedures to be completed 
at the follow-up visit can be found in the Flow Chart.  Patients will not do the PIFR 
measurements at home during the follow-up period.  Adverse events and concomitant 
therapies will be reviewed and recorded.  At the end of this follow-up visit, patient should be 
advised to continue with their regular COPD medication.

STATISTICAL METHODS AND DETERMINATION OF
SAMPLE SIZE
7.1
STATISTICAL DESIGN - MODEL
Design
This is a randomized, double-blind, placebo-controlled , multicenter, parallel group, study 
designed to assess efficacy of tiotropium + olodaterol delivered by Respimat® on FEV1
AUC0-3h and trough FEV1 in patients with moderate to severe COPD and in the subgroups of 
patients with peak inspiratory flow rate less than and greater than or equal to 60 L/min.
Objective
The primary objective of the trial is to describe the efficacy of inhaled tiotropium + 
olodaterol via Respimat® on lung function in patients with moderate to severe COPD and in 
the subgroups of patients with optimal and a sub-optimal PIFR.
7.2
NULL AND ALTERNATIVE HYPOTHESES
The following hypotheses will be tested in the study on the primary and key secondary 
endpoints. Each hypotheses will be tested in hierarchical order at 5% level of significance 
(two-sided) to protect the overall type I error at 5% (two-sided). The baseline value will be 
the measurement made prior to the first dosing at Visit 2.

H0-1: Mean FEV1 AUC0-3h change from baseline (tiotropium + olodaterol  via 
Respimat®) = Mean FEV1 AUC0-3h change from baseline (Placebo) in the optimal 
PIFR group at 4 weeks
vs.
H1-1: Mean FEV1 AUC0-3h change from baseline (tiotropium + olodaterol via 
Respimat®) ≠Mean FEV1 AUC0-3h change from baseline (Placebo) in the optimal 
PIFR group at 4 weeks.

H0-2: Mean FEV1 AUC0-3h change from baseline (tiotropium + olodaterol via 
Respimat®) = Mean FEV1 AUC0-3h change from baseline (Placebo) in the sub-optimal 
PIFR group at 4 weeks
vs.
H1-2: Mean FEV1 AUC0-3h change from baseline (tiotropium + olodaterol via 
Respimat®) ≠Mean FEV1 AUC0-3h change from baseline (Placebo) in the sub-optimal 
PIFR group at 4 weeks.

H0-3: Mean trough FEV1 change from baseline (tiotropium + olodaterol via 
Respimat®) = Mean trough FEV1 change from baseline (Placebo) in the optimal PIFR 
group at 4 weeks

vs.
H1-3: Mean trough FEV1 change from baseline (tiotropium + olodaterol  via 
Respimat®) ≠Mean trough FEV1 change from baseline (Placebo) in the optimal PIFR 
group at 4 weeks.

H0-4: Mean trough FEV1 change from baseline (tiotropium  + olodaterol via 
Respimat®) = Mean trough FEV1 change from baseline (Placebo) in the sub-optimal 
PIFR group at 4 weeks 
vs.
H1-4: Mean trough FEV1 change from baseline (tiotropium + olodaterol via 
Respimat®) ≠Mean trough FEV1 change from baseline (Placebo) in the sub-optimal 
PIFR group at 4 weeks.
Each of the tests will only be considered confirmatory if all previous tests are successful, 
i.e. the hypotheses tests were significant at 2-sided 5% level and the treatment effect favored 
tiotropium + olodaterol over placebo in each PIFR subgroup. 
7.3
PLANNED ANALYSES
The efficacy analysis will be performed in all randomized patients who were documented to 
have received any dose of trial medication and who have both baseline and any evaluable 
post-baseline measurement for at least one of the efficacy endpoints. This set will be called 
Full Analysis Set (FAS). The FAS definition will be fully specified or updated in the trial 
statistical analysis plan (TSAP).
For efficacy and safety analyses, patients will be analysed according to their planned 
treatment group.
7.3.1
Primary endpoint analyses
The primary endpoint will be analysed using an ANCOVA model including the fixed, 
categorical effect of treatment and the fixed continuous effect of baseline.
Significance tests will be based on adjusted means using a two-sided α = 0.05 (two-sided 
95% confidence intervals).
The primary analysis will be performed on the FAS within the optimal and sub-optimal PIFR 
groups, respectively. Patients will be analysed according to the PIFR stratum to which they 
belong (regardless of any misassignment to treatment based on identification of the wrong 
stratum), as such an error occurs before randomization and is therefore consistent with 
regulatory guidance.
To assess the homogeneity of the treatment effect on the primary endpoint across the levels 
of PIFR subgroups, the same ANCOVA model as in the primary analysis will be fitted in the 
overall population but replacing the treatment term by a treatment-by-PIFR subgroup term. A

descriptive p-value of treatment effect homogeneity at week 4 will be calculated. No overall 
treatment effect will be estimated from this model as it is not interpretable.
Similarly, the same ANCOVA model as in the primary analysis will be fitted in the overall 
population but replacing the treatment term by a treatment-by-continuous baseline PIFR term. 
A descriptive p-value of treatment effect homogeneity at week 4 will be calculated. No 
overall treatment effect will be estimated from this model as it is not interpretable.
The results of the analysis of the primary endpoints for tiotropium + olodaterol FDC within 
the optimal and sub-optimal PIFR groups will be presented in a forest plot and the treatment 
by PIFR subgroup interaction p-value will be provided. Sensitivity analysis will be performed 
by including additional covariates such as severity, gender and age in the model to adjust for 
potential differences in prognostic factors between sub-optimal and optimal PIFR subgroups.
7.3.2
Secondary endpoint analyses
The key secondary endpoint will be analysed using the restricted maximum likelihood 
(REML) based approach using a mixed model with repeated measurements (MMRM). The 
analysis will be performed on the FAS within the optimal and sub optimal PIFR groups, 
respectively.
The analysis will include the fixed, categorical effect of treatment at each visit and the fixed 
continuous effect of baseline at each visit. Visits will be treated as repeated measures with an 
unstructured covariance structure used to model the within-patient measurements.
The Kenward-Roger approximation will be used to estimate denominator degrees of freedom 
and adjust standard errors. Significance tests will be based on least-squares means using a 
two-sided α = 0.05 (two-sided 95% confidence intervals).
A selected set of analyses as that of the primary endpoint will be performed on the key 
secondary endpoint as well.
7.3.4
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 REP, a period of 
21 days after the last dose of trial medication, will be assigned to the treatment period for 
evaluation. All randomized patients who have taken at least one dose of study drug (i.e., the

treated set) 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. 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.
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.
Laboratory data will be analysed both quantitatively as well as qualitatively. The latter will 
be done via comparison of laboratory data to their reference ranges. Values outside the 
reference range as well as values defined as clinically relevant will be summarized. 
Treatment groups will be compared descriptively with regard to distribution parameters as 
well as with regard to frequency and percentage of patients with abnormal values or clinically 
relevant abnormal values.
Vital signs, physical examinations, or other safety-relevant data observed at screening, 
baseline, during the course of the trial and at the end-of-trial evaluation will be assessed with 
regard to possible changes compared to findings before start of treatment.
7.3.5
Interim Analyses
An interim analysis is not planned in this clinical trial.
7.4
HANDLING OF MISSING DATA
Missing completely at random is assumed for the primary endpoint as very little missing data 
is expected and no imputation will be performed.The REML-based MMRM model described 
in section 7.3.2 will handle missing data due to early drop outs or missing data in between 
visits which are assumed to be missing at random. Additional details on the imputation of 
missing data will be specified in the TSAP prior to unblinding.
7.5
RANDOMIZATION
Approximately 200 patients will be randomized in blocks to double-blind treatment stratified 
by PIFR optimal and sub-optimal subgroups Approximately equal numbers of patients will be 
randomized to each treatment group (50 in tiotropium + olodaterol Respimat® and 50 in
placebo Respimat® for each PIFR subgroup). BI will arrange for the randomization and the 
packaging and labelling of trial medication. The randomization 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 Clinical Trial Report. Access to the codes will be controlled and documented.

7.6
DETERMINATION OF SAMPLE SIZE
From previous studies, an appropriate estimate of the standard deviation (SD) for change 
from baseline in FEV1 AUC0-3h (Δ FEV1 AUC0-3h ) and trough FEV1 (ΔTFEV1) is 210 mL 
(c02098902-03, c02037872-05). Based on an assumed treatment difference of 260 ml in 
Δ FEV1 AUC0-3h and 140 ml in ΔTFEV1 between tiotropium + olodaterol Respimat® and 
placebo Respimat®, two-sided alpha of 0.05 and SD of 210 ml, a total of 98 patients will 
provide 99% power within the optimal and sub-optimal PIFR subpopulations for FEV1. 
AUC0-3h and 90% power for trough FEV1.The results of power calculations are shown in 
Tables 7.6: 1 and 7.6: 2.  From previous studies (c02098902-03, c02037872-05), the 
discontinuation rate is assumed to be low within the first 2-4 weeks.
Therefore, a sample size of 200 patients overall with 1:1 randomization ratio and 100 within 
each subpopulation (100 in optimal PIFR and 100 in sub-optimal PIFR) will provide 
adequate power to detect a treatment difference of 260 ml for FEV1 AUC0-3h and to detect a 
treatment difference of 140 ml for trough FEV1.

8.2
DATA QUALITY ASSURANCE
A risk-based approach is used for trial quality management. It is initiated by the assessment 
of critical data and processes for trial subject protection and reliability of the results as well as 
identification and assessment of associated risks.  An Integrated Quality and Risk 
Management Plan documents the rationale and strategies for risk management during trial 
conduct including monitoring approaches, vendor management and other processes focusing 
on areas of greatest risk.
Continuous risk review and assessment may lead to adjustments in trial conduct, trial design 
or monitoring approaches. 
A quality assurance audit/inspection of this trial may be conducted by the sponsor, sponsor’s 
designees, or by IRB / IEC or by regulatory authorities. The quality assurance auditor will 
have access to all medical records, the investigator’s trial-related files and correspondence, 
and the informed consent documentation of this clinical trial.
8.3
RECORDS
Electronic CRFs for individual patients will be provided by the sponsor. See section 4.1.5.2
for rules about emergency code breaks. For drug accountability, refer to section 4.1.8.
8.3.1
Source documents
In accordance with regulatory requirements, the investigator should prepare and maintain 
adequate and accurate source documents and trial records that include all observations and 
other data pertinent to the investigation on each trial patient. Source data as well as reported 
data should follow the “Attributable, Legible, Contemporaneous, Original, Accurate
(ALCOA) principles” and be attributable, legible, contemporaneous, original and accurate. 
Changes to the data should be traceable (audit trail).  Data reported on the eCRF must be 
consistent with the source data or the discrepancies must be explained.
The current medical history of the patient may not be sufficient to confirm eligibility for the 
trial and the investigator may need to request previous medical histories and evidence of any 
diagnostic tests. In this case, the investigator must make every attempt to retrieve previous 
medical records.
If the patient is not compliant with the protocol, any corrective action e.g. re-training must be 
documented in the patient file.
For the eCRF, data must be derived from source documents, for example:

Patient identification: gender, year of birth (in accordance with local laws and 
regulations)

Patient participation in the trial (substance, trial number, patient number, date patient was 
informed)

Dates of patient’s visits, including dispensing of trial medication

Medical history (including trial indication and concomitant diseases, if applicable)


Prior to allocation of a patient to a treatment into a clinical trial, there must be 
documented evidence in the source data (e.g. medical records) that the trial participant 
meets all inclusion criteria and does not meet any exclusion criteria.  The absence of 
records (either medical records or testing conducted specific for a protocol) to support 
inclusion/exclusion criteria does not make the patient eligible for the clinical trial.
8.3.2
Direct access to source data and documents
The sponsor will monitor the conduct of the trial by regular on-site monitoring visits.  The 
investigator /institution will allow site trial-related monitoring, audits, IRB / IEC review and 
regulatory inspections. Direct access must be provided to the eCRF and all source 
documents/data, including progress notes, copies of laboratory and medical test results, which 
must be available at all times for review by the CRA, auditor, and regulatory inspector 
(e.g. FDA). They may review all eCRFs and informed consents. The accuracy of the data 
will be verified by direct comparison with the source documents described in section 8.3.1.
The sponsor will also monitor compliance with the protocol and GCP.

APPENDICES
10.1
BODY PLETHYSMOGRAPHY MEASUREMENT TECHNIQUE
Detailed instructions on the procedures will be provided in a body plethysmography manual 
in the ISF.  The body plethysmography procedures will be performed in “linked” maneuver, 
i.e. without the patient coming off the mouthpiece prior to the completion of the maneuvers.

Quiet tidal volume breathing, ensuring stable End-expiratory Lung Volume (EELV), 
followed by

Shutter closing at EELV and panting with hands over cheeks, followed by

Opening of the shutter and return to quiet tidal breathing (ensuring stable EELVs, 
which are at the same position as those prior to shutter closing), followed by

An ERV maneuver, followed by a slow IVC maneuver.
Note:
The term “body plethysmography” is being used to specifically refer to body 
plethysmography system procedures that are performed with system´s door closed.
Spirometry (FEV1, FVC) will not be performed using the body plethysmography system, but 
rather with a stand-alone 
 spirometer supplied by a vendor designated by 
the sponsor.
Calculation of RV, TLC and IC:
Residual Volume (RV) is the volume of gas remaining in the lung at the end of a full 
expiration. The reported value for RV is the reported value for FRC minus the mean of 
technically acceptable ERV measurements, linked to technically acceptable FRC 
determinations (a maximum of six efforts).
Total Lung Capacity (TLC) is the volume of gas in the lung at the end of a full inspiration.  
The reported value of TLC is the reported value for RV plus the largest of the technically 
acceptable IVCs. A good quality IVC is thus required for the calculation of TLC. For IVC, 
the two best efforts (of at least three) MUST NOT differ by more than 150 mL. If 
repeatability is not achieved after three efforts, additional efforts up to a maximum of six 
need to be performed.
Inspiratory Capacity (IC) is the maximal volume which can be inspired from FRC. IC is 
calculated for each individual effort as the difference between IVC and ERV. At least three 
efforts must be performed, and the individual efforts must lie within ±6% of their mean. If 
repeatability is not achieved after three efforts, additional efforts of up to a maximum of six 
need to be performed.
