STUDY PERIODS
*
The visit interval (Visit 1-2) may be extended beyond 7 days for administrative reasons (1 additional week) or to 
allow for recovery from respiratory infections (4 weeks after recovery from the infection).
**
Clinic visits: every 3 months from visit 2
***
Phone calls: between clinic visits, every 6 weeks
****
Conclusion of patient participation also needs to be completed if the patient withdraws prematurely following 
randomisation.
1.
Informed Consent: all patients must sign an informed consent consistent with ICH-GCP guidelines prior to any study 
related activities which includes medication washout and restrictions. A preliminary check of in-/exclusion criteria with 
a particular focus on COPD exacerbation status within the previous year is recommended to avoid unnecessary study
procedures in non-eligible patients.
2.
FEV1/FVC: historical data from spirometry measurements within the past 3 months either at the site or at a referral site 
will be used. Spirometry results for COPD severity staging need to be in the patient file on site prior to randomisation.
For patients participating in the spirometry sub-study, historical data will not be used for inclusion.
3.
Medication restriction review: Refer to Table 4.2.2.1: 1 (Permitted Medications and Medication Restrictions)
4.
Visit 6/EoT procedures are to be completed by all patients at the time of study drug discontinuation. For patients who 
discontinue early, the Visit 6/EoT visit should be performed instead of the scheduled trial visit at time of 
discontinuation. Please complete directly Visit6/EoT eCRF pages.
6.
Physical examination, vital signs and laboratory results: to be performed only if relevant findings at Visit 6 (or last 
treatment visit in case of premature discontinuation). Please refer to section 5.2.3.1 (Laboratory tests) and section 
5.2.3.2 (Physical examination)
7.
For prematurely discontinued patients: Vital status and COPD exacerbation status collection: Please refer to section 
3.3.4.1
8.
Rescue medication: to be dispensed to all patients. Please refer to section 4.2.1.1
9.
Laboratory testing: fasted condition is not required
10. Inhalation device trainings: please refer to section 4.1.4.3
10a: visit1, training session with the Respimat® inhaler training medication (placebo)
10b: visit 2, training session with the new assigned Respimat® treatment box
10c: visits 3, 4 and 5. Observance of the inhalation procedure from the new assigned Respimat® treatment box
11. If applicable. Serum pregnancy test at Visits 1 and 6 or EoT and urine dipstick pregnancy test at Visits 2, 3, 4, 5 and 
follow-up.
13. Vital status collection has to be collected in all patients having discontinued prematurely:

BEFORE Visit 4: 2 collection time points at the originally predicted visit 4 and follow-up visit

AFTER Visit 4: 1 collection time point at the originally predicted follow-up visit
14. COPD exacerbation status collection: has to be collected in all patients having discontinued prematurely. 
Collection frequency repeated every 6 weeks at the originally predicted clinic visits and telephone contacts.

INTRODUCTION
1.1
MEDICAL BACKGROUND
Long-acting bronchodilators, such as long-acting muscarinic antagonists (LAMAs), are the 
cornerstone of maintenance therapy for patients with moderate to very severe chronic 
obstructive pulmonary disease (COPD) whose symptoms are not adequately controlled by 
short-acting bronchodilators alone [P13-05794, P14-01052].
An option recommended by GOLD for patients not adequately controlled on a single long-
acting bronchodilator is to combine a LAMA with a long-acting β2-agonist (LABA) [P14-
01052].This has prompted the development of combining LAMA+LABA as fixed-dose 
combinations (FDCs) [P13-05794]. 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. Several recent studies have provided 
evidence in support of this increased bronchodilatory effect when LABAs are added to 
LAMAs.
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. Fixed 
dose combinations of a short-acting β2–agonist and a short-acting anticholinergic have been 
developed and have been shown to be safe, efficacious and convenient for the patient (e.g., 
Combivent®: salbutamol+ipratropium bromide; [P94-1346]). The development of the novel 
once daily (quaque die (q.d.) )long-acting β2-agonist olodaterol now offers the opportunity 
for a once daily fixed dose combination including the well-established long-acting muscarinic 
antagonist tiotropium.
Olodaterol is a highly selective and nearly full β2 agonist [P10-07776, P11-07720] that 
provides 24-h bronchodilation in patients with COPD [P13-11467, P13-14112, P13-11346, 
P13-11345] Olodaterol is also associated with symptomatic benefit [P13-11341] and 
enhanced exercise capacity [P13-14109]. 
 
 
The complementary modes of action of tiotropium and olodaterol have previously been 
demonstrated in animal models, phase II clinical trials [P10-09337, P14-12073, P10-14042, 
P13-02357] and during the Phase IIIa programme, which has recently be finalised. 
 
 
 
In the Phase III programme the additional benefits of the tiotropium + olodaterol FDC over 
its mono-components has been assessed on lung function, quality of Life (St. George's 
Respiratory Questionnaire -SGRQ), dyspnea (Transition Dyspnea Index-TDI) and exercise 
endurance time. Another clinically important potential benefit of the tiotropium + olodaterol 
FDC over the mono components has so far not thoroughly been investigated, which is the

impact on exacerbations of COPD. Exacerbation related parameters have been included into 
the pivotal studies as a further endpoint, to inform the planning of this dedicated exacerbation 
studies. While the studied showed a consistent numerical trend for a reduction in 
exacerbations for the tiotropium + olodaterol FDC over tiotropium, the magnitude of this 
effect varied considerably in magnitude, depending on the study (1237.5 vs. 1237.6), patient 
sub-set (treated set vs. patients with an exacerbation history) and the exacerbation related 
outcome (time to first exacerbation vs. annual rate), as this can be expected in a non-powered 
study. 
1.2
DRUG PROFILE
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 Global initiative for chronic Obstructive Lung Disease [P14-01052] 2 
disease [P09-11278]).
Tiotropium in the dry powder inhaler HandiHaler has been approved in 
 
countries worldwide. An alternative aqueous formulation for use in the Respimat
inhaler 
(tiotropium 5μg q.d.) is approved in
 countries worldwide including EU and
Japan
. Further information 
about tiotropium can be found in the respective Summary of Product Characteristics (SPC)
for the product.
Tiotropium + olodaterol fixed dose 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 (approved in the EU and 
 other countries worldwide), olodaterol 
(approved in the EU and several other countries worldwide) and Combivent® (approved in 
the US). One cartridge is used per inhaler, which is inserted into the device prior to first use. 
In pivotal clinical trials and for the intended marketed product, the clinical dose consists of 
two actuations once daily. The RESPIMAT inhaler uses mechanical energy to create a soft 
mist which is released over a period of approximately 1.5 seconds.
In the pivotal studies (1237.5/.6), tiotropium + olodaterol FDC showed statistically 
significant improvements in FEV1 Area under the curve (AUC0-3h) response and trough 
Forced expiratory volume in one second (FEV1) response after 24 weeks compared to the 
mono-components and these improvements were maintained up to 52 weeks. The 
bronchodilatory profile of the combination was confirmed in a supportive 6-week study
(1237.20), in which the mean FEV1 improvements over 24 hours were superior to the mono-
components, with improvements in forced vital capacity (FVC), inspiratory capacity (IC), 
functional residual capacity (FRC), morning peak expiratory flow rate (PEFR) and evening 
PEFR supporting the results for FEV1.

Tiotropium + olodaterol FDC showed statistically significant improvements in health-related 
quality of life (SGRQ) and dyspnoea experienced during everyday activities (TDI) after 24 
weeks compared to the mono-components. More patients treated with the combination had an 
improvement in SGRQ total score and TDI greater than the Minimal clinically important 
difference (MCID).
Treatment with tiotropium + olodaterol FDC resulted in reductions in both daytime and night 
time rescue bronchodilator use compared to the mono-components and patients treated 
perceived a greater improvement in their respiratory condition, as measured by a Patient´s 
Global Rating scale.
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.
In conclusion, the clinical trials conducted to date have shown tiotropium + olodaterol FDC 
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 
the combination compared to the individual components translated into benefits that were 
meaningful to the patient, with improvements in several patient centred outcomes. For further 
information please refer the Investigators Brochure for the Tio+Olo FDC [c01735808].

RATIONALE, OBJECTIVES, AND BENEFIT - RISK 
ASSESSMENT
2.1
RATIONALE FOR PERFORMING THE TRIAL
According to the GOLD guidelines, exacerbations are important events in the course of 
COPD as they have major impact on the patient`s quality of life and cause an increase in 
symptoms and a deterioration of lung function that may take several weeks to recover from. 
Moreover an exacerbation will accelerate the decline of lung function and is associated with 
significant mortality, especially if a hospitalisation is needed. It is without doubt, that 
exacerbations are associated with significant socioeconomic costs [P14-01052]
The benefits of tiotropium + olodaterol (5/5 μg) FDC that have been studied in the Phase III 
program include improvements in lung function, quality of life, dyspnea and exercise 
endurance time, but the benefit on exacerbations has not formally been assessed.
2.2
TRIAL OBJECTIVES
The aim of this study is to demonstrate that once daily treatment with tiotropium 5 µg + 
olodaterol 5 µg fixed dose combination will reduce the number of exacerbations over 
tiotropium 5 µg monotherapy. 
A secondary aim of the study is an assessment of a potential impact of tiotropium 5 µg + 
olodaterol 5 µg FDC on hospitalisation associated with exacerbations and survival, as 
compared to tiotropium 5 µg monotherapy. The latter will be included as secondary 
endpoints.
See section 5 for details concerning endpoints.
2.3
BENEFIT - RISK ASSESSMENT
The potential benefits of a treatment with tiotropium and tiotropium + olodaterol (5/5 μg)
FDC from the Respimat have been described above. Tiotropium is a well-established
maintenance treatment for patients with COPD across all severities. 
The clinical trials conducted to date have shown tiotropium + olodaterol (5/5 μg) FDC to be a 
safe, well tolerated and efficacious combination therapy according to treatment guidelines in 
a moderate to very severe COPD patient population (including patients with concomitant
cardiovascular diseases). 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. Potential 
risks associated with administration of tiotropium include the listed (expected) adverse events 
for tiotropium monoproduct ([U92-0551]).
Potential risks associated with administration of the combination of tiotropium and olodaterol 
include the listed (expected) adverse events for tiotropium + olodaterol (5/5 μg) FDC.

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].
The trial design requires that patients will be randomized at Visit 2 (1:1) to one of the 
following treatments:
i.
Tiotropium + olodaterol FDC (2.5 µg / 2.5 µg per actuation) inhalation solution 
ii.
Tiotropium (2.5 µg / per actuation) inhalation solution (control group)
There is no placebo comparator in this trial.
Patients taking commercial tiotropium with/without LABAs will take their maintenance 
treatment up to the day prior to the randomization visit (visit 2).
Patients receiving inhaled corticosteroids before enrolment will continue their treatment (or 
the inhaled corticosteroids component alone if taken as a fixed combination with 
bronchodilator) at the same 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 rescue SABA and permitted use of other maintenance medications in 
conjunction with close clinical monitoring for exacerbation symptoms.
During the whole course of the trial Boehringer Ingelheim will provide open-label 
salbutamol/albuterol HFA MDI to be used as rescue medication for all patients after they 
have signed their informed Consent.
Safety will be monitored (as described in Section 5.2) at site visits and at each telephone
contact alike. Patients will be contacted by site staff and asked for COPD exacerbation status, 
adverse events and change in concomitant therapy.
The study will be conducted under the guidance of a Steering Committee (SC).
An adjudicated analysis of all deaths will be also performed by an independent Mortality 
Adjudication Committee (MAC) in a blinded manner.
In conclusion, the proposed assessment of a potential added benefit of olodaterol to the 
known effects in reducing exacerbations shown with tiotropium alone is an important medical 
and health economic question. Therefore the potential benefits for patients outweigh potential 
risks and justify clinical development of tiotropium + olodaterol (5/5 μg) FDC.

DESCRIPTION OF DESIGN AND TRIAL POPULATION
3.1
OVERALL TRIAL DESIGN AND PLAN
This is a randomised, double-blind, active-controlled parallel group, phase IIIb study to 
evaluate the effect of 52 weeks of once daily treatment of orally inhaled tiotropium + 
olodaterol (5/5 μg) fixed dose combination compared with tiotropium on Chronic Obstructive 
Pulmonary Disease (COPD) exacerbation in patients with severe to very severe COPD and 
with one or more moderate to severe COPD exacerbation during the previous 12 months. 
The study is multinational and involves more than 50 participating countries.
The trial consists of three consecutive study periods including the screening, the treatment 
and follow-up periods. An overview of the trial design is shown in Figure 3.1:1.
Figure 3.1:1 Study Design
Having obtained the signed informed consent, the patient will be entered in a maximum 7-
day screening period to confirm the patient’s eligibility. At Visit 2 after a successful review 
of the inclusion and exclusion criteria, the patient will be randomly allocated in equal ratio to 
receive once daily study treatment (Refer to section 4.1.2) and will then enter the 52-week 
treatment phase. The randomised treatment period consists of five 3-monthly clinic visits and 
in the interim a telephone contact will be scheduled every 6 weeks (Refer to Flow chart).
The planned on-treatment period will begin with the administration of the first dose of trial 
medication and until the completion of visit 6/EoT.

The patient’s trial participation will be concluded with the follow-up visit 21 days after 
V6/EoT.
For visit details please refer to section 6.2.
Patients who prematurely discontinue from their treatment period will be followed for vital 
status and COPD exacerbation status via phone calls until their predicted normal exit date 
from the trial (i.e. 52 weeks after taking the first dose of randomised treatment + 21 days). 
Please refer to section 3.3.4.1 and section 6.2.4.
Adverse events and moderate to severe COPD exacerbation events will be documented 
throughout the trial, i.e. starting with informed consent and ending 21 days after last 
administration of trial medication.
3.1.1
Administrative structure of the trial
Sponsor: Boehringer Ingelheim, as trial sponsor, will provide funding and trial materials, 
including study medication.  The sponsor has appointed a Trial Clinical Monitor (TCM), 
responsible for coordinating the activities required in order to manage the trial in accordance 
with applicable regulations and internal Standard Operating Procedures (SOPs), directing the 
clinical trial team in the preparation, conduct, and reporting of the trial, order the materials as 
needed for the trial, ensures appropriate training and information of local clinical monitor 
(CML), Clinical Research Associates (CRAs), and investigators of participating country.
Data Management and Statistical evaluation will be done by BI according to BI SOPs. For 
these activities, a Trial Data Manager and a Trial Statistician have been appointed.
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 (as protocol reference if 
applicable) are in the investigator site file (ISF) and the trial master file (TMF) document.
Co-ordinating Investigator: the coordinating investigator is selected based on 
 expertise in 
this therapeutic area and reputation for being a leader in 
 field.
 will review the trial 
protocol, any subsequent amendments to the protocol and the Clinical Trial Report (CTR). 
 will provide 
 signature on the final protocol signature page and amendments and will 
provide 
 signature on the CTR indicating that, to the best of Co-ordinator’s knowledge, the 
final CTR accurately describes the conduct and results of the Trial.
Targeted group of Investigators: all physicians/qualified sites with access to the requested 
patient population and the facilities required to conduct the study assessments. The sites have 
to be able to perform electrocardiogram (ECG) and to conduct the procedure of blood 
sampling for clinical haematology and biochemistry. Patients will be treated on an outpatient 
basis. Recruitment is competitive. However, it is anticipated that each site will enrol an 
average of 10-12 patients. Beyond this commitment, sites will be able to include more 
patients after discussion and agreement with the TCM.

Mortality Adjudication Committee (MAC): an independent mortality adjudication committee 
will be established for the blinded adjudication of all fatal cases in the trial.
A MAC Charter, under which the principles of the study design can be carried out, will 
govern their activities. The charter will provide detailed definitions of each endpoint and the 
processes by which adjudication will occur, including how blinding will be preserved.
Centralized laboratory: The sample transport logistics (from site to sponsor) and blood 
analysis will be the responsibility of the central laboratory. The central laboratory will 
provide sampling, urine dip stick pregnancy test and shipment materials.
ECG: A standard 12-lead electrocardiogram will be performed on all patients at the screening 
visit using the site´s own equipment.
Pulmonary function testing: historical spirometry data from measurements within the past 3
months either at the site or at a referral site may be used for inclusion into the trial. No 
spirometry equipment needs to be available at the site. Should for practical reason, the 
pulmonary function testing (PFT) be performed at the trial site, the spirometers and their use, 
including daily calibration, must meet ATS/ ERS criteria (P05-12782).
IRT: an Interactive Response Technology (IRT) system will be used for randomisation in this 
trial and for allocation of trial medication to patients throughout the treatment period. The 
ability to unblind will be available to the investigator via IRT.
Patient’s reminder card: all patients will be provided with a paper diary to serve as a reminder 
to support the structured COPD questionnaire clinic and telephone interview.
Trial documentation: all trial relevant documentation will be stored by Boehringer Ingelheim 
in the clinical trial master file (TMF). Trial relevant documentation for the trial sites will be 
filed in the Investigator Site File (ISF) at the investigator sites.

3.2
DISCUSSION OF TRIAL DESIGN, INCLUDING THE CHOICE OF 
CONTROL GROUP
A randomised, double-blind trial design with parallel treatment groups is a well-established 
design to compare beneficial effects of once-daily tiotropium+olodaterol FDC and tiotropium
on moderate to severe COPD exacerbations. Tiotropium has shown in numerous studies that 
it reduces the risk for a COPD exacerbation. Therefore tiotropium is the logical choice as 
active comparator for this trial. 
End of study is defined as last patient out. This will be after the last patient has received their 
last dose of study drug and completed the follow-up visit 21 days thereafter. 
The control group
The control group comprises the same type of COPD patients who are randomly allocated to 
receive tiotropium 5 µg Respimat®.
3.3
SELECTION OF TRIAL POPULATION
It is widely accepted that a COPD exacerbation increases the risk of the occurrence of future 
COPD exacerbations and that the frequency of exacerbations increases with progression of
COPD. The trial will recruit patients with severe lung function impairment and a history 
occurrence of moderate to severe treated COPD exacerbations, as these patients are known to 
have greater likelihood of having a re-occurrence of COPD exacerbation. The eligibility 
criteria employed in the study will allow enriching the patient population by ensuring the 
recruitment of patients prone to exacerbations.
This trial will be conducted worldwide and the distribution of patients between the countries 
will be dependent on the access to suitable patients as well as the operational feasibility of 
performing the trial in the country. It is anticipated that each site will enrol an average of 10 
to 12 patients.
An estimated total of 7800 patients randomised will be necessary to assess the primary 
endpoint “Annualised rate of moderate to severe COPD exacerbation during the treatment 
period”. Between Visit 1 and Visit 2, a low screen failure rate of 5% is foreseen due to the 
short screening period and, therefore, a lower likelihood for the enrolled patient to experience 
a new COPD exacerbation before the randomisation visit.
A log of all patients included into the study (i.e. having given 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
Main diagnosis for study entry
Outpatients with a history of COPD with severe to very severe pulmonary impairment 
(according to GOLD guideline) and having a documented history of at least one treated


The patient withdraws consent, without the need to justify the decision.

The patient is no longer able to participate for medical reasons (e.g. pregnancy,
surgery, adverse events, or other diseases. 

Administrative reasons (protocol violations, persistent non-compliance).
No patient should be discontinued from the trial for a protocol violation before discussion 
with the clinical monitor. To be considered complete, a patient must complete all treatment 
visits (including telephone contacts) as specified in the flow chart.
Withdrawal from the screening phase
As long as a patient has not been assigned to a study treatment at Visit 2 (by IRT), the patient 
is not considered to belong to the treatment phase.  Prior to the randomisation, reasons for 
withdrawal can be connected with the criteria described in the section 3.3.4.1 or related to 
eligibility criteria (please refer to section 3.3.2 and 3.3.3).The data of patients who withdraw 
prior to randomisation will be entered in the trial database and will be listed.
Withdrawal from the treatment phase
If the patient has prematurely stopped taking the investigational product during the treatment 
phase, the withdrawn patient will be followed-up for vital status and COPD exacerbation 
status until the end of the planned treatment period of 52 weeks + 21 days. The objective is to 
collect information on vital status (dead or alive) and COPD exacerbation status in the time 
interval between the patients' withdrawal date from the treatment period and their predicted 
exit date. Please refer to section 6.2.3.2.
Please note
1. A patient should not be withdrawn from the trial because he/she experiences a COPD 
exacerbation during the treatment period.
2. If during the treatment period, the trial medication is for any reason (e;g. 
hospitalisation stay) interrupted more than 14 consecutive days, a discussion with the 
clinical monitor is required to re-assess the patient’s participation in the study.
Refer to Section 6.2.3 for procedures to be followed for patients prematurely terminating the 
trial.
3.3.4.2 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:

Failure to meet expected enrolment goals overall or at a particular trial site,

Emergence of any efficacy/safety information that could significantly affect 
continuation of  the trial 

Violation of GCP, the CTP, or the contract by a trial site or investigator, disturbing 
the appropriate conduct of the trial.

Method of assigning patients to treatment groups
When a patient is qualified for entry into the randomised treatment period, treatment 
assignment will be by means of a third-party phone/web-based randomisation on Visit 2. This 
will involve the use of an Interactive Response Technology (IRT) system which will 
implement a randomisation scheme generated using a validated randomisation software by 
Boehringer Ingelheim.
Refer to Section 4.1.6 for details on packaging and labelling.
Note that the Respimat® treatment box number 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 programme 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. An additional dose of tiotropium + 
olodaterol FDC has been studied during the Phase III programme, consisting of 2.5 µg 
tiotropium and 5 µg olodaterol. In the pivotal trials, a consistent difference in favour of 
tiotropium + olodaterol FDC 5/5 μg compared to tiotropium + olodaterol FDC 2.5/5 μg was 
demonstrated over the 52 week treatment period across various measures of lung function 
and patient-reported outcomes. 
Tiotropium + olodaterol FDC 5/5 μg demonstrated 
statistically significant and clinically relevant benefit over the individual components in all 
primary and secondary endpoints. On the other hand, the lung function improvement for 
tiotropium + olodaterol FDC 2.5/5 μg was more modest and a statistically significant benefit 
was not demonstrated in the pre-specified symptomatic primary endpoint, SGRQ total score.
Based on these observation, the tiotropium + olodaterol FDC 5/5 µg has been submitted for 
regulatory approval and is therefore considered to be the most 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 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. At Visit 2 
eligible patients will be randomized to one of two double-blinded treatment arms (1:1 ratio) 
by the IRT. At subsequent clinic visits (every 3 months), the IRT will assign Respimat®
treatment boxes to each patient and each Respimat® treatment box will have a unique number 
with 6 digits. 
One of these Respimat® treatment boxes is a reserve Respimat® inhaler. This 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 electronic case report form (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. 
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
For the patient’s sake of convenience regarding the trial drug administration, the clinic visit 
must be scheduled in the morning. During the treatment phase the patient will be instructed to 
withhold the morning dose of the trial medication in current use prior to come to visits 3, 4 
and 5 to avoid overdosing. 
The last administration of the study medication will be taken at visit 6 (EoT) from the
Respimat® inhaler that is in current use since no new Respimat® treatment box will be 
assigned.
Study medication administration at clinic visits
Dispensation and Respimat® inhaler assembling
Trial medication will be dispensed at visits 2, 3, 4 and 5. Patients will receive 3 new 
Respimat® treatment boxes + 1 Respimat® inhaler reserve. If the reserve kit is unused and 
intact, the IRT will not dispense a replacement reserve kit. 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 deputy. 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 3, 4, 5 and 6 all used and unused Respimat® will be returned to the clinic by the 
patient. If the reserve kit is unused and intact, the IRT will not dispense a replacement reserve 
kit.
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.
The patient will be asked to record any missed dose of study medication in a patient’s 
reminder card.
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. Throughout the course of the study treatment period, the correct usage of their 
inhalation medications should be regularly re-instructed (ideally at each clinic visit) based on 
the package insert. 
Respimat®
Training on the use of the Respimat® inhaler will first be provided to the site staff who will 
subsequently train the 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 2: after the randomization, the second 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 instructed.

Subsequent clinic visits: observance of the inhalation procedure. 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*) 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.
4.1.4.4
Respimat® malfunctioning
Any Respimat® inhaler that has been reported as malfunctioning by a patient or investigator 
will be returned to Boehringer Ingelheim 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.
4.1.5
Blinding and procedures for unblinding
4.1.5.1
Blinding
Patients, investigators and everyone involved in analysing or with an interest in this double-
blind study will remain blinded with regard to the randomised treatment assignments until 
after database lock.
Boehringer Ingelheim will generate and store the randomisation schedule, and prepare and 
code the medication in a blinded fashion. Trial supplies will be assigned to the patients via 
IRT.
Refer to Section 4.1.5.2 for rules of breaking the code in emergency situations.
4.1.5.2
Procedures for emergency unblinding
The ability to unblind will be available to the investigator via the IRT. Unblinding must only 
be used in emergency situations when the identity of the study drug must be known by the 
investigator to provide appropriate medical treatment. Each site receives a manual from the 
IRT provider that contains instructions on how to unblind the treatment of a patient via the 
IRT (via 24-hour Emergency helpline). If possible, the Clinical Monitor Local (CML) and 
Trial Clinical Monitor (TCM) must be contacted prior to the site unblinding a patient's 
treatment. Patients unblinded to treatment will be withdrawn from the trial.
4.1.6
Packaging, labelling and re-supply
Boehringer Ingelheim will provide all study supplies including blinded study medication, 
rescue medication and Respimat® inhaler training kits. Expiry date will be pre-printed on the

TREATMENT COMPLIANCE
Each patient will be trained in the correct use of the Respimat® inhaler using the training 
Respimat® inhaler with inserted placebo cartridge. Please refer to section 4.1.4.3.
Patients will be asked to return inhalation aerosols and devices (used and unused) to the study 
site. The 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 should provide the estimate of the number of 
puffs that should have been administered by the patient three or four Respimat® inhalers used 
during that period of time.
The Respimat® inhaler contains 60 actuations (30 daily 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 actuations) left.  
The dose indicator scale is divided into 4 quarters. One-quarter used accounts for 7 days of 
treatment (14 actuations).
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. Over a period of 3 months that is to say between 2 
clinic visits, patient should return 3 Respimat® inhalers empty (the dose indicator has reached 
the end of the red scale). The acceptable medication compliance should have an overall value

in the range from 80% to 100%. If the compliance is less than 80% the patient needs to be re-
trained. Please refer to section 4.1.4.3.
Randomised patients should not be discontinued for a lack of compliance without prior 
discussion with the local clinical monitor.

Endpoints of efficacy
Primary endpoint

Annualised rate of moderate to severe COPD exacerbation during the treatment period
(within 1 day* after the last drug administration date).
Key secondary endpoint

Time to first moderate to severe COPD exacerbation during the treatment period
(within 1 day* after the last drug administration date).
Secondary endpoints 

Annualised rate of exacerbation leading to hospitalisation during the treatment period 
(within 1 day* after the last drug administration date).

Time to first COPD exacerbations leading to hospitalisation during the treatment 
period (within 1 day* after the last drug administration date).

Time to all-cause mortality (within 1 day* after the last drug administration date).

5.1.2
Assessment of efficacy
5.1.2.1 Definition of moderate and severe COPD exacerbations
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 a prescription of antibiotics and / or systemic 
steroids and/or hospitalisation.
A complex of lower respiratory events / symptoms is defined as at least two of the following:

Shortness of breath

Sputum production (volume)

Change in sputum colour

Cough

Wheezing

Chest tightness
“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:
Mild: 
a new prescription of maintenance bronchodilator only
Moderate: 
patient receiving an exacerbation-related prescription of oral corticosteroids 
and/ or antibiotic not requiring hospitalisation.
Severe: 
COPD-related hospitalisation including emergency room visit*
To consider hospitalisation associated with COPD exacerbation, the information collected 
should include the start date of all COPD-related hospitalisations as well as the discharge date 
from the hospital or equivalent

*Visit in emergency is defined as: an unscheduled emergency room visit resulting in
prescription of oral corticosteroids and/ or antibiotic.
Only the investigator-diagnosed COPD exacerbation fitting the above criteria of moderate to
severe COPD exacerbation will be used for the analysis of the annualized moderate to severe 
exacerbation rate as the primary endpoint. 
5.1.2.2 Assessment of moderate and severe COPD exacerbations
Information regarding exacerbations will be collected by the physicians during the visits and 
will be recorded in the eCRF. During all telephone calls and clinic visits, the same questions
regarding exacerbation will be addressed for collecting exacerbation-related details and then 
recorded in the eCRF.
At every clinical visit, the investigator will be asked to review (not to collect) the patient’s 
reminder card and all telephone calls since the last clinical visit to ensure that all 
exacerbations have been recorded and that the exacerbations meet the definition of study 
exacerbation.
The investigator (or deputy) will record the COPD exacerbation information the length of 
time the patient is treated with the trial medication but also for patients who will discontinue 
early. 
For all patients (completed/discontinued) the COPD exacerbation collection time of interest
will be the planned 52-week + 21 days starting from visit 2.
If patients are hospitalised, the study site will be responsible for collecting and reviewing 
pertinent medical records so that an informed judgment can be made as to the primary cause 
for admission.
Patient’s reminder card
The patient’s reminder card will be used to note changes in symptoms, missed dose 
medication or utilisation of health care services between visits and serve as a reminder for the 
patients. The patient reminder cards will not be collected by the site and remains the 
exclusive property of the patient. The patient will complete reminder cards entries daily from 
Visit 2 until the follow-up visit. 
In case of withdrawal from the treatment phase, discontinued patients are encouraged to 
complete their reminder cards in order to be able to answer questions on their COPD 
exacerbation status.

Assessment of adverse events
5.2.2.1
Definitions of adverse events
Adverse event
An adverse event (AE) is defined as any untoward medical occurrence, including an 
exacerbation of a pre-existing condition, in a patient in a clinical investigation who received a 
pharmaceutical product. The event does not necessarily have to have a causal relationship 
with this treatment.
Serious adverse event
A serious adverse event (SAE) is defined as any AE which results in death, is immediately 
life-threatening, results in persistent or significant disability / incapacity, requires or prolongs 
patient hospitalisation, is a congenital anomaly / birth defect, or is to be deemed serious for 
any other reason if it is an important medical event when based upon appropriate medical 
judgement which may jeopardise the patient and may require medical or surgical intervention 
to prevent one of the other outcomes listed in the above definitions.
Cancers of new histology or exacerbations of existing cancer are considered serious adverse 
events. 
Vital status and COPD exacerbation status from patients who prematurely discontinue 
treatment will be collected.
ADDITIONAL INFORMATION FOR JAPAN:
The following events will be handled as “deemed serious for any other reason”. An AE which 
possibly leads to disability will be reported as an SAE. Every new occurrence of cancer will 
be reported as a SAE regardless of the duration between discontinuation of the drug and the 
occurrence of the cancer.

This document may not - in full or in part - be passed on, reproduced, published or otherwise used without prior written permission.
Intensity of adverse event
The intensity of the AE should be judged based on the following:
Mild:
Awareness of sign(s) or symptom(s) which 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 adverse event
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. Assessment of causal relationship should be recorded in the case report forms. 
ADDITIONAL INFORMATION FOR JAPAN:
The reason for the decision on causal relationship needs to be provided in the eCRF.
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. 
If a SAE is reported from a still blinded trial, the causal relationship must be provided by the 
investigator for all potential trial drugs, i.e. the BI trial drug and for all other trial drugs (i.e. 
any active comparator).
The Investigator (or designee) will enter these events (even if they meet the criteria of an 
SAE) in the corresponding pages in the eCRF within 24 hours of awareness, as well as 
providing any defined supporting documentation This will be provided by the Sponsor to the 
AC, as defined in the charter.
Worsening of the underlying disease or other pre-existing conditions
Worsening of the underlying disease or of other pre-existing conditions will be recorded as an 
(S)AE in the eCRF.
Changes in vital signs, physical examination, and laboratory test results
Changes in vital signs, physical examination and laboratory test results will be recorded as an 
(S)AE in the eCRF , if they are judged clinically relevant by the investigator.
Protocol-specified adverse events of special interest (AESIs)
There are no protocol-specified adverse events of special interest (AESIs) in this trial.

5.2.2.2
Adverse event and serious adverse event reporting
All adverse events, serious and non-serious, occurring during the course of the clinical trial 
(i.e., from signing the informed consent onwards through the follow-up period until 21 days
after the last administration of trial medication) will be collected, documented and reported to 
the sponsor by the investigator on the appropriate eCRFs / SAE reporting forms. Reporting 
will be done according to the specific definitions and instructions detailed in the ‘Adverse 
Event Reporting’ section of the Investigator Site File. 
For each adverse event, the investigator will provide:

Onset date

End date

Intensity

Treatment required

Outcome

Seriousness*

Action taken with the investigational drug. 

Causal relationship: SAEs and non-serious AEs must include a causal relationship 
assessment of the investigational drug made by the investigator as defined in 
section 5.2.2.1. 
The investigator must report the following events via telephone/fax using the SAE form 
immediately (within 24 hours or the next business day, whichever is shorter) to the sponsor: 
SAEs and non-serious AEs relevant to the reported SAE.
With receipt of any further information to these events, a follow-up SAE report has to be 
provided. SAEs and non-serious AEs must include a causal relationship assessment made by 
the investigator.
Always serious adverse events 
BI has set up a list of AEs which are defined to be always serious. The list of these adverse 
events can be found via the RDC-system. In order to support the investigator with the 
identification of these “always serious adverse events”, if a non serious AE is identified to be 
serious per BI definition, a query will be raised. The investigator must verify the description 
and seriousness* of the event.  If the event description is correct, the item “serious” needs to 
be ticked and an SAE has to be reported in expedited fashion following the same procedure 
as above.
With receipt of any further information to these events, a follow-up SAE report has to be 
provided. 
ADDITIONAL INFORMATION FOR JAPAN: this information must be also reported 
immediately to the head of the trial site.
The SAE form is to be forwarded to the defined unique entry point identified for the BI OPU 
(country-specific contact details will be provided in the Investigator Site File). This 
immediate report is required irrespective of whether the investigational product has been

administered or not and irrespective of causal relationship. It also applies if new information 
to existing SAEs or protocol-specified adverse events becomes available. 
AE and SAE reporting including the Follow-up period
The investigator also has the responsibility to report all serious and non-serious AEs 
occurring within the 21 days (+ 7 days of agreed time window) residual effect period. Any 
AEs reported to the sponsor during this period must be documented in the safety database.
All events with an onset after the first dose of trial medication up to a period of 21 days (+ 7 
days) after the last dose of trial medication will be assigned to the treatment period for 
evaluation.
AE and SAE reporting after the follow-up period
The Investigator does not need to actively monitor patients for AEs once the clinical trial has
ended. However, if the Investigator becomes aware of an SAE that occurred after the patient
has completed the clinical trial (including the follow-up period), the Investigator should 
report it to the sponsor if the Investigator considers it relevant to BI investigational product.
Pregnancy
In rare cases, pregnancy might occur in clinical trials. Once a female subject has been 
enrolled into the clinical trial, after having taken study medication, the investigator must 
report immediately any drug exposure during pregnancy to the sponsor. Drug exposure 
during pregnancy has to be reported immediately (within 24 hours or next business day 
whichever is shorter) to the defined unique entry point for SAE forms of the respective BI 
OPU (country-specific contact details will be provided in the Investigator Site File). The 
study medication must be interrupted without delay (i.e.; as soon as pregnancy is known).
The outcome of the pregnancy associated with the drug exposure during pregnancy must be 
followed up. In the absence of an (S)AE, only the Pregnancy Monitoring Form for Clinical 
Trials and not the SAE form is to be completed. 
The ISF will contain the Pregnancy Monitoring Form for Clinical Trials (Part A and Part B).
5.2.2.3
Vital status collection
The vital status collection will only concern patients having prematurely withdrawn BEFORE 
their predicted trial exit date. For the period of interest and frequency of survival information, 
please refer to section 3.3.4.1. The vital status information does not require a patient visit. If 
no information can be collected after at least 3 attempted (documented) phone calls and at 
least one registered letter, the patient will be regarded as lost to follow-up.
5.2.3
Assessment of other safety parameters
The safety endpoints will also evaluate vital signs, routine laboratory evaluations and 
physical examination.

5.2.3.1 Laboratory tests
Clinical laboratory testing will be conducted on all patients at Visits 1 and 6/EoT. The fasted 
condition is not required. The laboratory tests at Visit 1 will be considered as the baseline 
measurements and the results of the Visit 1 tests have to be assessed by the investigator or 
designee prior to randomisation, to ensure no exclusion criteria are met.
Follow-up clinical laboratory testing must be performed at the follow-up visit if there are any 
clinically significant findings at the last study treatment visit (for completed patient = visit 6). 
It is the responsibility of the investigator to evaluate changes in laboratory value and 
reporting of adverse event should be followed according to the definition outlines in section

Pulmonary Function Testing
IF HISTORICAL DATA IS NOT AVAILABLE: the qualifying pulmonary function tests are
to be conducted at the investigational site. Subsequently, patients must have completed
spirometry at or within 3 months of the screening visit that meet the post-bronchodilator 
criterion listed in Section 3.3.2 for inclusion into the trial. Measurements of FEV1 and FVC 
will be performed using calibrated electronic spirometers at the investigational site or a 
referral site. Spirometers and their use, including daily calibration, must meet American 
Thoracic Society (ATS)/ European Respiratory Society (ERS) criteria (P05-12782).  
Spirometry will be conducted with the patient in a seated position. The test will be conducted 
in triplicate. The highest FEV1 and FVC from an acceptable maneuver will be recorded 
regardless of whether they come from different spirometric maneuvers or from the same 
maneuver ( preferably with a maximum of five attempts).

INVESTIGATIONAL PLAN
6.1
VISIT SCHEDULE
All patients are to adhere to the visit schedule as specified in the Flow Chart. Some flexibility 
is allowed in scheduling the visits according to visit time windows as specified in the Flow 
Chart. If any visit has to be rescheduled, subsequent visits should follow the original visit 
date schedule (calculated from Visit 2). The trial medication kits contain sufficient 
medication to allow for these time windows. All deviations from the planned visit schedule 
will be documented.
The screening period should be restricted as much as possible to avoid any exacerbation 
episode during this period. For a patient in stable condition screening procedures should be 
completed within 7 days (between visit 1 and visit 2). The qualifying PFT and safety 
laboratory report must be available to confirm the eligibility at least on the day of 
randomization (Visit 2).
However, the screening period (between Visit 1 and Visit 2) may be extended by an 
additional 1 week for administrative reasons.
In case of respiratory tract infections or exacerbation during the screening period: visit 2 can 
be postponed 4 weeks following the recovery from the infection or exacerbation (based on 
the last dose of systemic corticosteroids and/or antibiotics). The complete procedures and 
observations of Visit 1 are to be repeated to ensure the complete review of the In/Ex criteria 
at Visit 2.
Rescheduling visits after Visit 2
If rescheduling of clinic visits after the randomisation is necessary, the total daily dose of the 
study medication needs to be maintained and the use of the reserve trial medication is 
recommended to continue the treatment without any interruption.
Any rescheduling of visits should be discussed with your monitor.

6.2
DETAILS OF TRIAL PROCEDURES AT SELECTED VISITS
A preliminary check of in-/exclusion criteria with a particular focus on COPD exacerbation 
within the previous year is recommended to avoid unnecessary study procedures in non-
eligible patients.
A complete overview of assessments to be performed at each visit is provided in the trial 
Flow Chart. 
 
 
6.2.1
Screening period
Informed consent will be obtained prior to patient participation in the trial, which includes 
any medication washout procedures or restrictions. The study requirements, including the 
procedure for the follow-up of prematurely withdrawn patients must be fully explained to the 
patient and written informed consent obtained prior to initiating any study-related evaluation.
Patients will be assigned a study patient number by the Remote Data capture (RDC) system
once consent is signed. The site should also register the patient as a screened patient in IRT.
Eligibility will be assessed at the initial screening visit and confirmed at the randomisation 
visit (Visit 2). Patients who fail to complete all of the testing procedures will not be re-
enrolled at a later date.

6.2.2.3 Telephone contacts between clinic visits
Study sites will follow up patients and collect information by telephone interviews every 6-
week (± 7 days). A patient’s reminder card will be provided to assist their memory recall in 
terms of respiratory symptoms, COPD exacerbations, hospitalisation or interim health care 
visits, concomitant therapy.
At each telephone contact, the investigator or deputy will review with the patient any related 
COPD exacerbation information (new occurrence of exacerbation, respiratory symptoms, 
COPD exacerbation-related hospitalisation etc…) and will record it in the eCRF. If patients 
are hospitalised, the study site will be responsible for collecting and reviewing pertinent 
medical records so that an informed judgment can be made as to the primary cause for 
admission.
Relevant sources of information may include hospital records, telephone or written 
correspondence with primary physicians, discharge summaries, and death certificates.
Emphasis will be placed on the first diagnosis listed in the discharge summary in determining 
the primary cause for the hospital admission. In case of hospitalisation, patients will be 
encouraged to inform the study site prior to their regularly scheduled telephone interviews.
Details of all exacerbations will be captured in the source notes.

Premature discontinuation
The Visit 6/EoT visit should be performed instead of the scheduled trial visit at time of 
premature discontinuation (Please refer to section 6.2.3.1). Afterwards, the initiation of the 
survival and exacerbation information collection will be initiated.
The need for follow-up information (vital status and COPD exacerbation) should have been
explained to patients prior to their participation in the trial and will be part of the written 
informed consent.
COPD exacerbation status collection
The collection of the COPD exacerbation status will be repeated every 6 weeks at the 
originally predicted clinic visits and telephone contacts until the predicted Visit 6.
Exacerbation contact information will be reported on the “COPD exacerbation check” eCRF. 
Exacerbation-related details will likewise recorded as an (S)AE and recorded in the COPD 
event eCRF, if applicable. In order to be able to provide COPD information, patients are 
strongly encouraged to use and complete the patient’s reminder card until the completion of 
the collection period.
Starting from the premise that COPD exacerbation and vital status collection should be 
timely aligned with the originally planned clinic visits and telephone contact. If the patient is 
not reachable during this period a second attempt is to be planned later (reason documented
i.e: hospitalization, holiday, family events….).

Vital status collection
Depending on the time of the patient’s withdrawal, the survival status collection will be 
scheduled as following:
o
BEFORE Visit 4: 2 collection time points at the originally predicted visit 4 (26 
weeks from Visit 2) and follow-up visit (52 weeks + 21 days from Visit 2)
o
AFTER Visit 4: 1 collection time point at the originally predicted follow-up 
visit (52 weeks + 21 days from Visit 2).
The time interval of interest will be defined from the date of the Termination of Trial 
Medication (TTM) until their predicted follow-up visit.
If death occurs, the investigator will review the circumstances, including the relevant medical
records to ascertain the most likely primary cause. Vital status information will be collected
in accordance with national ethical and regulatory guidelines.
6.2.4
Follow-up visit
At the completion of the Visit 6 the follow-up visit should be performed in any case as

STATISTICAL METHODS AND DETERMINATION OF 
SAMPLE SIZE
7.1
STATISTICAL DESIGN - MODEL
This is a randomised, double-blind, active-controlled parallel group, phase IIIb study. The 
primary objective of this study is to evaluate the effect of once daily treatment of tiotropium 5 
μg + olodaterol 5 μg FDC delivered by the Respimat® inhaler on COPD exacerbation as 
compared with 5 μg tiotropium delivered by the Respimat® inhaler in patients with severe to 
very severe COPD. Each patient will stay in the trial for 52 weeks and will be followed up 
for COPD exacerbation if dropped out earlier. Vital status will be collected over the entire 
study period (52 weeks + 21 days follow-up).
7.2
NULL AND ALTERNATIVE HYPOTHESES
The effect of tiotropium + olodaterol FDC on COPD exacerbation will be assessed by testing 
the rate ratio for annual rate of moderate/severe COPD exacerbation and hazard ratio for  
moderate/severe COPD exacerbation between T+O FDC and Tio 5 in the following 
hypothesis testing hierarchy:
9. H10: the annualised rate of moderate to severe COPD exacerbation is equal between T+O 
5/5 and Tio 5
vs.
H11: the annualised rate of moderate to severe COPD exacerbation is different 
between T+O 5/5 and Tio 5.
10. H20: the survival distribution for the onset of the first moderate to severe COPD 
exacerbation is equal for T+O 5/5 and Tio 5
vs.
H21: the survival distribution for the onset of the first moderate to severe COPD 
exacerbation is different for T+O 5/5 and Tio 5
This hypothesis testing strategy ensures that the overall type I error is protected at two-sided 
0.01 level.
7.3
PLANNED ANALYSES
7.3.1
Primary analyses
The primary analysis includes all randomised patients who are documented to have received 
any dose of study medication, i.e., the primary analysis is performed using the treated set.
The primary endpoint, i.e., annualised rate of moderate to severe COPD exacerbation will be 
analysed using a negative binomial model including the fixed, categorical effect of treatment

as well as the logarithm of the treatment exposure as an offset. In all analyses of annualised 
rate of event, the length of the event will be subtracted from the extent of exposure or the 
length of the observation period because one cannot expect to have another event during an 
event. Moderate to severe COPD exacerbations occurring within 1 day (i.e.: 24 hours) after 
the last drug administration date are included in the primary analysis.
7.3.2
Secondary analyses
For the key secondary endpoint, i.e., time to the onset of the first moderate to severe COPD 
exacerbation, as well as other time to event endpoints (see Section 5.1.1), a Cox’s 
proportional hazard model will be used to estimate the hazard ratio and the corresponding 
99% confidence intervals, while log-rank test will be used to obtain the p-value for testing the 
survival curves. For other annualised rate of event endpoints (see Section 5.1.1), the same 
negative binomial model as specified for the primary endpoint will be used.
For all efficacy analyses including time to all-cause mortality the treated set (on-treatment + 1 
day) will be used. 
 
 
 
 
 
 
7.3.3
Safety analyses
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 
prospectively.
Adverse events will be coded using the current version of the Medical Dictionary for 
Regulatory Activities (MedDRA) coding dictionary. Standard BI summary tables and listings 
will be produced to compare the incidence of adverse events across treatment groups. All 
adverse events with an onset after the first dose of trial medication and up to 21 days after the 
last dose of trial medication will be assigned to the on-treatment period. Other adverse events

HANDLING OF MISSING DATA
Since patients are followed up for exacerbations and vital status and the CAT questionnaire is 
an exploratory endpoint, missing data will not be imputed. Missing safety data will not be 
imputed with the exception of missing AE dates which will be imputed according to BI 
standards.

Randomly missing data (not due to worsening of disease or use of rescue medication) after 
inhalation for which there are data from that visit both before and after inhalations will be 
linearly interpolated. Randomly missing data with no subsequent non-missing values for that 
visit will be imputed using the last observation carried forward (LOCF) techniques prior to 
calculating AUC.
7.5
RANDOMISATION
Patients will be randomised in equal ratio to one of the two treatment groups in this trial and 
blocked randomisation will be used. Boehringer Ingelheim will generate the randomisation 
scheme and will prepare and code the medications to maintain the double-blind.
In order to maintain flexibility for drug supply, each individual medication kit will have a 
separate identification number. Assignment of medications at the clinic visits will be 
accomplished through the use of IRT. Each patient will be assigned a single randomisation 
number indicating the randomised treatment the patient will be on throughout the trial. BI 
will provide the randomisation and medication kit number lists to the IRT and the sites will 
access the IRT to obtain the randomisation number and medication kit numbers to be 
dispensed to the patient.
7.6
DETERMINATION OF SAMPLE SIZE
Based on a recent publication on the SPARK study (Wedzicha, et al, Lancet, 2013) and data 
from a previous BI study 
, the rate ratio and hazard ratio of moderate to severe 
COPD exacerbation between T+O  FDCs and Tio 5 are assumed to be 0.88.
Assuming an annualised rate of moderate to severe COPD exacerbation for Tio 5 to be 0.85, 
a 12-month fixed study duration, two-sided type I error rate of 0.01 and 90% power, the 
sample size depends on the dispersion parameter for the negative binomial distribution. Table 
7.6: 1 gives the sample size estimations for a range of the dispersion parameters. In addition, 
assuming a 15% loss of information in patient-years, the estimated power corresponding to 
the sample size is also provided in the last column in Table 7.6: 1 below.

The above calculation is based on the formulas in Zhu and Lakkis [P14-09564] and was
calculated using the validated software package R. A sample size of 3900 patients per arm 
will give a power between 90% to 94% under different dispersion parameters to detect a rate 
ratio of 0.88 between T+O FDC and Tio 5 in the annualised rate of moderate to severe COPD 
exacerbation assuming the annual rate in Tio 5 is 0.85 and two-sided type I error rate of 0.01. 
After adjusting for a 15% loss of information in patient-years and the same assumptions as 
above, a sample size of 3900 patients per arm will give a power between 86.1% to 90.6% 
Assuming the proportion of patients who had at least one moderate to severe COPD 
exacerbation within 1 year in the Tio 5 arm is 0.65, a hazard ratio between T+O FDC and Tio 
5 of 0.88, a two-sided type I error rate of 0.01 and power of 90%, the estimated sample size 
for time to the first moderate/severe COPD exacerbation is 2915 patients per arm (using 
nQuery Advisor 7.0). A sample size of 3900 patients per arm will give a power of 97% using 
the same assumptions.
A sample size of 3900 patients per arm or 7800 patients in total is selected for this trial 
because it provides acceptable power to detect a 12% reduction in annualised rate of 
moderate to severe COPD exacerbation of T+O FDC as compared with Tio 5 using a two-
sided type I error rate of 0.01, under a reasonable range of dispersion parameters of the 
negative binomial distribution and assuming the annual rate in Tio 5 is 0.85. This sample size 
also gives sufficient power to detect a 12% reduction in the hazard rate of moderate to severe 
COPD exacerbation of T+O FDC as compared to Tio 5 at a two-sided type I error rate of 0.01 
and assuming the proportion of patients who had at least one moderate/severe COPD 
exacerbation after 1 year in the Tio 5 arm is 0.65.

INFORMED CONSENT, DATA PROTECTION, TRIAL
RECORDS
The trial will be carried out in compliance with the protocol, the principles laid down in the 
Declaration of Helsinki, in accordance with the ICH Harmonised Tripartite Guideline for 
Good Clinical Practice (GCP) and relevant BI Standard Operating Procedures (SOPs). 
Standard medical care (prophylactic, diagnostic and therapeutic procedures) remains in the 
responsibility of the treating physician of the patient.
The investigator should inform the sponsor immediately of any urgent safety measures taken 
to protect the study subjects against any immediate hazard, and also of any serious breaches
of the protocol/ICH GCP.
The rights of the investigator and of the sponsor with regard to publication of the results of 
this trial are described in the investigator contract. As a general rule, no trial results should be 
published prior to finalisation of the Clinical Trial Report.
ADDITIONAL INFORMATION FOR JAPAN:
For Japan and the Japanese GCP regulations (Ministry of Health and Welfare Ordinance 
No.28, March 27, 1997).
The rights of the investigator/trial site and of the sponsor with regard to publication of the 
results of this trial are described in the investigator/trial site’s contract.
Insurance Cover: The terms and conditions of the insurance cover are made available to the 
investigator and the patients via documentation in the ISF (Investigator Site File).
8.1
STUDY APPROVAL, PATIENT INFORMATION, AND INFORMED 
CONSENT
This trial will be initiated only after all required legal documentation has been reviewed and 
approved by the respective Institutional Review Board (IRB) / Independent Ethics Committee 
(IEC) and competent authority (CA) according to national and international regulations. The 
same applies for the implementation of changes introduced by amendments.
Prior to patient participation in the trial, written informed consent must be obtained from each 
patient (or the patient’s legally accepted representative) according to ICH GCP and to the 
regulatory and legal requirements of the participating country. Each signature must be 
personally dated by each signatory and the informed consent and any additional patient-
information form retained by the investigator as part of the trial records. A signed copy of the 
informed consent and any additional patient information must be given to each patient or the 
patient’s legally accepted representative.
Informed consent procedure and Vital Status information collection
In order to successfully maintain the safety objectives of this trial, it is necessary that each 
patient’s COPD exacerbation follow-up and vital status be maintained until the predicted

patient’s exit date (i.e. 52 weeks (+ 1 week) +21 days after taking the first dose of 
randomized treatment). For this reason the informed consent includes a COPD exacerbation 
collection and vital status statements. All patients will agree to be followed for COPD 
exacerbation and vital status as a part of the informed consent procedure. Hence, patients who 
withdraw prematurely from study treatment will still be periodically contacted 
(approximately every 6 months contact) to determine survival status and every 6 weeks to 
collect COPD exacerbation status.
The patient must be informed that his/her personal trial-related data will be used by 
Boehringer Ingelheim in accordance with the local data protection law. The level of 
disclosure must also be explained to the patient.
The patient must be informed that his / her medical records may be examined by authorised 
monitors (CML/CRA) or Clinical Quality Assurance auditors appointed by Boehringer 
Ingelheim, by appropriate IRB / IEC members, and by inspectors from regulatory authorities.
The investigator must give a full explanation to trial patients by using the patient information 
form, which is prepared avoiding the use of technical terms and expressions. The patient is 
given sufficient time to consider participation in the trial. The investigator obtains written 
consent of the patient’s own free will with the informed consent form after confirming that 
the patient understands the contents. The investigator must sign (or place a seal on) and date 
the informed consent form.
If a trial collaborator has given a supplementary explanation, the trial collaborator also signs
(or places a seal on) and dates the informed consent.
8.2

sponsor via remote data capture. 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
Source documents provide evidence for the existence of the patient and substantiate the 
integrity of the data collected. Source documents are filed at the investigator’s site.
Data entered in the eCRFs that are transcribed from source documents must be consistent 
with the source documents or the discrepancies must be explained. The investigator may need 
to request previous medical records or transfer records, depending on the trial; also current 
medical records must be available.
The patient’s reminder card will not be collected by the site.
For eCRFs all data must be derived from source documents.
8.3.2
Direct access to source data and documents
The investigator / institution will permit trial-related monitoring, audits, IRB / IEC review 
and regulatory inspection, providing direct access to all related source data / documents. 
eCRFs and all source documents, including progress notes and copies of laboratory and 
medical test results must be available at all times for review by the sponsor’s clinical trial 
monitor, auditor and inspection by health authorities (e.g. FDA). The Clinical Research 
Associate (CRA) / on site monitor and auditor may review all eCRFs, and written informed 
consents. An adaptive approach to clinical trial monitoring that directs monitoring focus and 
activities to the evolving areas of greatest risk which have the most potential to impact 
subject safety and data quality will be utilised. The accuracy of the data will be verified by 
reviewing the documents described in Section 8.3.1.

LISTEDNESS AND EXPEDITED REPORTING OF ADVERSE EVENTS
8.4.1
Listedness
To fulfil the regulatory requirements for expedited safety reporting, the sponsor evaluates 
whether a particular adverse event is "listed", i.e. is a known side effect of the drug or not. 
Therefore a unique reference document for the evaluation of listedness needs to be provided. 
For the 5 μg tiotropium inhalation solution this is the current version of the Investigator’s 
Brochure [U92-0551]. For the Fixed Dose Combination of tiotropium and olodaterol this is 
the current version of the Investigator’s Brochure [c01735808]. For the non-investigational 
medicinal product salbutamol/albuterol, the reference document is the US-PI (Proair HFA).
The current versions of these reference documents are to be provided in the ISF. No AEs are 
classified as listed for matching placebo (for training purposes only), study design, or 
invasive procedures.
8.4.2
Expedited reporting to health authorities and IECs/IRBs
Expedited reporting of serious adverse events, e.g. suspected unexpected serious adverse 
reactions (SUSARs) to health authorities and IECs/IRBs, will be done according to local 
regulatory requirements. Further details regarding this reporting procedure are provided in the 
Investigator Site File.
8.5
STATEMENT OF CONFIDENTIALITY

THE RESPIMAT INHALER
Instructions for Use
Respimat® inhaler
How to use your RESPIMAT® inhaler
This leaflet explains how to use and care for your RESPIMAT® inhaler. Please read and carefully 
follow these instructions.
The RESPIMAT® inhaler releases medication slowly and gently, making it easy to inhale it into your 
lungs.
The RESPIMAT® inhaler enables you to inhale the medicine contained in a cartridge. You will need 
to use this inhaler only ONCE A DAY. Each time you use it take 2 PUFFS. In the box you will 
find the RESPIMAT® inhaler and the RESPIMAT® cartridge. Before the RESPIMAT ® inhaler is used 
for the first time, the cartridge provided must be inserted.

Daily use of your RESPIMAT® inhaler
You will need to use this inhaler only ONCE A DAY. 
Each time you use it take TWO PUFFS.
I
I
Hold the RESPIMAT® inhaler upright, with the grey cap (A) 
closed, to avoid accidental release of dose. Turn the base (G) in 
the direction of the red arrows on the label until it clicks (half a 
turn).
II
II
Open the grey cap (A) until it snaps fully open. Breathe out 
slowly and fully, and then close your lips around the end of the 
mouthpiece without covering the air vents (C). Point your 
RESPIMAT® inhaler to the back of your throat.  
While taking in a slow, deep breath through your mouth, press 
the dose release button (D) and continue to breathe in slowly 
for as long as you can. Hold your breath for 10 seconds or for 
as long as comfortable.
III
Repeat steps I and II so that you get the full dose.
You will need to use this inhaler only ONCE A DAY.
Close the grey cap until you use your RESPIMAT® inhaler 
again.
If the RESPIMAT® inhaler has not been used for more than 3 days release one 
puff towards the ground. If the RESPIMAT® inhaler has not been used for 
more than 21 days repeat steps 4 to 6 until a cloud is visible. Then repeat steps 
4 to 6 three more times.
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.
Further information
The RESPIMAT® inhaler must not be disassembled after inserting the cartridge and replacing the 
clear base.
Do not touch the piercing element inside the base.
Keep out of the reach and sight of children.
Do not freeze.

ADDITIONAL INFORMATION REGARDING IN/EX CRITERIA
Calculation of predicted normal values according to ECSC
For height measured in inches
Males: FEV1 predicted (L) = 4.30 x [height (inches)/39.37] – 0.029 x [age (yrs)] – 2.49
Females: FEV1 predicted (L) = 3.95 x [height (inches)/39.37] – 0.025 x [age (yrs)] – 2.60
For height measured in meters
Males: FEV1 predicted (L) = 4.30 x [height (m)] – 0.029 x [age (yrs)] – 2.49
Females: FEV1 predicted (L) = 3.95 x [height (m)] – 0.025 x [age (yrs)] – 2.60
Post-bronchodilator
FEV1< 60% of predicted normal (ECSC) and 
post-
bronchodilator FEV1/FVC <70% of predicted normal (ECSC): documentation
Patients may not be randomised to the study without the availability of spirometry data at 
the actual study site.
Historical data
To be performed within the past 3 months either at the site or at a referral site will be 
used. 
A referral letter and signed copies of the measurement printouts must be provided to the 
trial site for source data verification. However, any referral documentation does not result 
in the need to open “satellite sites”.
In case several qualifying spirometry measurements are available, the most recent one 
should be referred to as long as it was not performed during an exacerbation. 
OR
PFT measurement at investigational site:
Patient must be able to perform a post-dose pulmonary function test after the 
administration of 400 μg salbutamol/albuterol (preferred) for qualification.
OR: testing with either 200 μg salbutamol/albuterol or a combination of 
salbutamol/albuterol with ipratropium bromide (2 to 4 actuations) is acceptable.
The spirometers and their use, including daily calibration, must meet American Thoracic 
Society (ATS)/ European Respiratory Society (ERS) criteria.
