1.
Informed consent should be obtained before any study procedure including the shipment of the HRCT image and 
biopsy sample (if available) for central review. 
2.
At visit 1, height measurement should be included.
3.
PK samples will be taken at Visits 3, 6 and 10 just prior to drug administration. Patients will be provided with a PK 
card/diary to support the record of the exact clock time of medication intake three days prior to PK sampling.
4.
Blood samples for serum banking and pharmacogenetics may be drawn from all randomised patients who received at 
least one dose of trial medication and who gave a separate informed consent. Patients will be asked to participate in 
the biobanking subset, i.e. pharmacogenetic and serum biobanking. Still, the participation is voluntarily and not a pre-
requisite for participation in the trial. The single pharmacogenetic sample will be drawn at Visit 2 or at any other 
subsequent visit after randomisation. Serum banking samples shall be drawn as per Flow Chart.
5.
SGRQ, UCSD-SOBQ: the first procedure at the clinic.
6.
Patient diary will be issued at Visit 2 and will be reviewed at each clinic visit up until Visit 10. Content to be discussed 
and reviewed by the site staff as it pertains to AEs and concomitant therapy and times of drug intake three days prior 
to the PK sampling.
7.
Including acute IPF exacerbations
8.
Patients who prematurely discontinue from the trial and don’t accept to attend all planned visits will be contacted for 
vital status collection at week 52.
9.
No fasting required.
10.
If performance compliance is below 80% or as deemed necessary by the site.

11.
To be performed after pre-dose PK sample (if applicable) and after current visit exams.
12.
Perform only if abnormal or findings needing follow-up recorded at Visit 10.
13.
Visit 1 should only be conducted after IPF diagnosis has been confirmed by central review. 
14.
In case of dose change of nintedanib (reduction or re-escalation), dose adjustment visit must be conducted to allow 
dispensing of new medication kit.
15.
Early end of treatment visit to be completed for all patients who withdraw or discontinue study treatment prematurely.
Patients who prematurely discontinue treatment will then be invited to attend all visits as planned until week 52 (Visit 
10).
16.
Screening period (period between Visit 1 and 2) should last 14 days (2 weeks). The screening period may be 
prolonged by additional 2 week for any reasons, i.e. total 28 days (4 weeks). Eligible patients can be randomised once 
central lab results have been received and are found to be consistent with eligibility criteria.  
17. 
4 days prior to planned PK sampling site should preferably contact the patient to record times of drug intake within 
patient diary. Patient should record times of drug intake three days prior to the PK sampling.
18.
In women of childbearing potential.
19. 
Applicable only if patient doesn’t accept to attend remaining scheduled visits.

INTRODUCTION
MEDICAL BACKGROUND
1.1
Idiopathic pulmonary fibrosis (IPF) is a rare disease of unknown aetiology that is 
characterized by progressive fibrosis of the interstitium of the lung, leading to decreasing 
lung volume and progressive pulmonary insufficiency [P11-07084].
The course of the disease in individual patients is variable: some patients progress rapidly,
others have periods of relative stability punctuated by acute exacerbations and others progress 
relatively slowly. Acute exacerbations of IPF are events of respiratory deterioration of 
unidentified cause that occur in 5–10% of patients annually and are associated with a very 
poor outcome [R12-2786]. 
IPF is most prevalent in middle aged and elderly patients, and usually presents between the 
ages of 40 and 70 years. The median life expectancy in IPF patients after diagnosis is 2 to 3 
years [P11-07084].
The latest update on clinical practice guideline for the treatment of IPF, jointly issued in 2015
by the American Thoracic Society (ATS), European Respiratory Society (ERS), Japanese 
Respiratory Society (JRS) and Latin American Thoracic Association (ALAT) has provided a 
conditional recommendation for treatment with nintedanib or pirfenidone for the majority of 
IPF patients, taking into account individual patient values and preferences [P15-07362]. 
Conventional IPF treatments such as n-acetylcysteine (NAC), corticosteroids, 
cyclophosphamide, cyclosporine and azathioprine are not approved treatments for IPF, and 
their efficacy is questionable or even harmful [P15-07362; P12-06085; P14-07665]. Non-
pharmacological therapies such as pulmonary rehabilitation and long-term oxygen therapy 
are recommended for some patients, but their efficacy in patients with IPF has not been 
established. Lung transplant has been shown to positively impact survival in patients with 
IPF. [R11-5086; R12-2785]. Although the number of patients transplanted due to IPF has 
increased steadily over the last years, the scarce availability of donor organs, as well as the 
comorbidities and advanced age preclude many patients from referral to lung transplant [R12-
3676; R12-3474].
Pirfenidone, a compound which demonstrated anti-fibrotic activity in non-clinical models, 
was first licensed in Japan in 2008 based on two local trials which showed a reduced decline 
of vital capacity under treatment with the compound [R06-2070; R10-4316]. In the
international Phase III CAPACITY program, pirfenidone demonstrated efficacy on the 
primary FVC lung function endpoint in only one of two confirmatory trials [R11-4827]. The
additional confirmatory ASCEND Phase III trial requested by FDA met the primary endpoint 
of change from baseline FVC % predicted [R14-2103]. Pirfenidone is also licensed since 
February 2011 for the treatment of mild to moderate IPF in the European Union and since 
October 2014 for the treatment of IPF in the United States of America. It is also licensed in
several other countries.
Nintedanib is a small molecule intracellular tyrosine kinase inhibitor which has demonstrated 
anti-fibrotic and anti-inflammatory activity in preclinical models [P08-08684; P14-02860]. 
The two replicate Phase III INPULSIS trials and the Phase II TOMORROW trial consistently 
showed positive results for the efficacy of nintedanib 150 mg twice daily versus placebo in

patients with IPF. Both INPULSIS trials showed that nintedanib reduced the annual rate of 
decline in FVC (mL/year) by approximately 50%, consistent with slowing disease 
progression [P14-07514; P11-11216]. Based on these three clinical trials, nintedanib was 
approved for the treatment of IPF in the USA in October 2014, in the European Union in 
January 2015 and in Japan in July 2015. As of 20 October 2015, nintedanib has also been 
approved in Canada, Switzerland, Russia, Australia, Chile, Ecuador and Taiwan and it has 
been submitted for marketing authorization in other countries across the world.
Although nintedanib and pirfenidone can be considered a standard of care for patients 
diagnosed with IPF, it remains unclear when to start and when to stop treatment with either of 
the drugs, given the unpredictability of clinical course in the individual patient as well as the 
lack of biomarkers to inform patient management and therapeutic response.
With the introduction of nintedanib in the treatment algorithm of IPF, there is an additional 
need to further characterize its profile in patients at an early disease stage, i.e. in patients with  
limited lung volume impairment, and to address the question when to start treatment in these 
patients. Currently, many physicians apply a wait and watch strategy for these patients as 
there are no markers to predict the individual course in a given patient or response to 
treatment which may result in a delay of treatment initiation. Identifying biomarkers to 
predict the clinical course and benefits of therapy for a given patient early in the course of the 
disease remains one of the most urgent and relevant challenges in patient management
DRUG PROFILE
1.2
Nintedanib is a small molecule that inhibits a distinct spectrum of receptor tyrosine kinases 
(RTKs) and non-receptor tyrosine kinases (nRTKs) at pharmacologically relevant 
concentrations. Among them, FGFR (fibroblast growth factor/receptor), PDGFR (platelet 
derived growth factor/receptor) and VEGFR (vascular endothelial growth factor/receptor) 
have been implicated in IPF pathogenesis. Nintedanib binds competitively to the adenosine 
triphosphate (ATP) binding pocket of these receptors and blocks the intracellular signalling 
which is crucial for the proliferation, migration, and transformation of fibroblasts 
representing essential mechanisms of the IPF pathology [P08-08684; P14-02860]. 
A soft gelatin capsule formulation of nintedanib is used in humans. Maximum plasma 
concentrations occur between 2 - 4 hours after oral administration. Steady state is reached at 
the latest within one week of dosing. After food intake, a trend towards an increased systemic 
exposure (around 15 to 20%) and a delayed absorption was observed compared to 
administration under fasted conditions. Nintedanib is recommended to be taken with food. 
Nintedanib is preferentially distributed in plasma, with a blood to plasma ratio of 0.87; the 
terminal half-life is in the range of 7 to 19 h. The absolute bioavailability of nintedanib was 
slightly below 5%. Nintedanib is mainly eliminated via faeces.
Co-administration of nintedanib with the P-glycoprotein (P-gp) inhibitor ketoconazole 
increased exposure to nintedanib by 60-70% based on area under the curve (AUC) and by 
80% based on a maximum measured concentration of the analyte in plasma (Cmax) in a 
dedicated drug-drug interaction (DDI) study. Patients taking potent P-gp inhibitors (e.g 
ketoconazole, erythromycin or cyclosporine) should be monitored closely for tolerability of 
nintedanib.

In a DDI study with the P-gp inducer rifampicin, exposure to nintedanib decreased to 50.3% 
based on AUC and to 60.3% based on Cmax upon co-administration compared to 
administration of nintedanib alone. Since potent P-gp inducers may decrease exposure to 
nintedanib, selection of alternative treatment with no or minimal P-gp induction should be 
considered. 
The clinical efficacy of nintedanib has been studied in over 1400 patients with IPF in one 
phase II dose finding study (TOMORROW) including four different doses of nintedanib, and 
two replicate phase III (INPULSIS 1 and 2) trials. These were randomised, double-blind, 
placebo-controlled studies comparing treatment with nintedanib twice daily to placebo for 52 
weeks. A statistically significant reduction in the annual rate of decline of FVC (in mL) was 
demonstrated in patients receiving nintedanib 150 mg bid compared to patients receiving 
placebo. The treatment effect on FVC was consistent in all 3 studies, i.e. a relative reduction 
of approximately 50% between nintedanib and placebo. Furthermore, nintedanib 150 mg bid 
significantly reduced the risk of first acute exacerbation compared with placebo in 
INPULSIS-2 and in the TOMORROW trial, and reduced the risk of adjudicated 
confirmed/suspected acute exacerbations by 68% in a pre-specified sensitivity analysis of  
pooled data from the INPULSIS® trials, supporting the effect of nintedanib on slowing 
disease progression [P14-07514; P11-11216].
The safety profile of nintedanib has been investigated comprehensively. The proportion of 
patients with serious adverse events was similar in the nintedanib and placebo groups. 
The risks of treatment with nintedanib in adult patients are primarily related to the 
gastrointestinal tract (nausea, vomiting, diarrhea, abdominal pain) and to increases in liver 
enzymes aspartate aminotransferase (AST), alanine transaminase (ALT), alkaline 
phosphatase (ALP), gamma-glutamyl transferase (GGT) and bilirubin. The most frequently 
reported adverse event was diarrhea which was mild to moderate in intensity for the vast 
majority of patients and lead to treatment discontinuation in less than five percent of patients 
treated with nintedanib. Weight decrease and decreased appetite have also frequently been 
reported in studies with nintedanib. 
Potential risks of nintedanib treatment also include arterial hypertension, GI perforations, 
thromboembolism and bleeding. Patients treated with full-dose anticoagulation or at known 
risk for bleeding were excluded from the INPULSIS trials. This has led to recommendations 
stating that patients at known risk for bleeding should be treated with nintedanib only if the 
anticipated benefit outweighs the potential risk. Although cardiac disorder AEs were 
balanced between the nintedanib and placebo groups, a higher proportion of patients in the 
nintedanib groups had myocardial infarctions. Conversely, a lower proportion of patients in 
the nintedanib groups had other ischemic heart disease. ‘Other ischemic heart disease’ was a 
pre-defined category including terms such as coronary artery disease, angina pectoris, 
coronary angioplasty, coronary artery stenosis, myocardial ischemia, coronary artery stent 
insertion, electrocardiogram (ECG) ST segment depression. The clinical significance of this 
finding is unknown, and further observation is needed.
For patients finalizing the 52 week study treatment in the TOMORROW and INPULSIS 
trials, participation in open label extension trials (1199.35 and 1199.33) was offered. Long 
term treatment in these still ongoing open label extension trials confirm the safety profile 
observed in the phase II and III trials [P15-09876].

Nintedanib has also demonstrated efficacy and tolerable safety in patients with non-small cell 
lung cancer who failed first line treatment [P11-00203], as well as in patients with advanced 
renal cell cancer [P13-06268], ovarian cancer [P11-10116] and hepatocellular carcinoma

RATIONALE, OBJECTIVES, AND BENEFIT - RISK 
ASSESSMENT
RATIONALE FOR PERFORMING THE TRIAL
2.1
Until recently, IPF was essentially an untreatable disease. With the availability of specific 
antifibrotic drugs like nintedanib and pirfenidone, a major advance in the management of IPF 
has been achieved. However, based on the heterogeneity of disease progression and the lack 
of validated prognostic biomarkers, the clinical course in an individual patient remains
unpredictable which is also true for the individual response to treatments.
Retrospective studies have identified several factors at a single point in time (baseline 
factors) or over time (longitudinal factors) that are associated with increased mortality in IPF. 
Change in physiologic measures over time, such as absolute decline in FVC % predicted 
normal by 10% or more, are associated with reduced survival; This association is only seen 
after a minimum of 6-12 months [R06-4127; R10-6539; P05-02699; R06-4126]. However, 
change in pulmonary function in the prior year does not predict the subsequent change in 
pulmonary function in the following year [R14-1149]. In addition, none of these markers has 
been validated prospectively. Several serum proteins at baseline (e.g. KL-6, MMP-7, 
surfactant protein D) have also been shown to weakly correlate with the clinical course of the 
disease [R15-4126 ; R10-6378 ; R15-4125], but none of these markers have been assessed 
longitudinally.
A key hallmark in the pathology of IPF is dysregulation in connective tissue turnover within 
the lungs, resulting in excessive accumulation of distorted extracellular matrix and scarring 
which is considered a final common pathway in lung fibrosis. This deranged equilibrium is 
determined by several components including fibroblast proliferation, migration and 
differentiation, ECM synthesis by active myofibroblasts, collagen cross-linking and matrix 
degradation by various enzymes like metalloproteinases (MMPs). 
The prospective observational PROFILE study [R15-1220] has recently shown that disease 
progression and prognosis can be determined through temporal changes in extracellular 
biomarkers indicating the defective and excessive matrix turnover potentially directly 
reflecting disease activity. In addition, the magnitude of change in ECM biomarkers related 
to the subsequent risk of disease progression and these changes provided the ability to predict 
outcome at an earlier stage (after 3 months) compared to physiologic measures of lung 
function. It remains to be determined whether baseline or change in ECM biomarkers will 
predict response to treatment.
Identifying biomarkers to predict the clinical course and benefits of nintedanib therapy, e.g. 
effect of nintedanib on surrogate biomarkers early in the course of the disease remains one of 
the most urgent and relevant challenges to improve overall patient management, prevent 
treatment delay or overtreatment.
This study is conducted to examine for the first time the treatment effect of nintedanib on 
change of biomarkers indicative of extracellular matrix turnover which have been shown 
recently to predict disease progression in the PROFILE study [R15-1220].

This study further aims to confirm the association of biomarker course during the first three 
months of treatment and disease progression as observed in PROFILE and to assess whether 
nintedanib treatment during the first 12 weeks alters this association or not.
TRIAL OBJECTIVES
2.2
The primary objective of the trial will be to assess the effect of nintedanib on rate of change 
in extracellular matrix (ECM) turnover biomarker CRPM over 12 weeks which has shown to
strongly associate with disease progression in patients with IPF in the PROFILE cohort
[R15-1220].
A secondary objective is to confirm the observed results from the PROFILE cohort, i.e. to 
assess the predictive value of change in extracellular matrix (ECM) biomarkers CRPM, C1M 
and C3M over 12 weeks for disease progression as defined by FVC decline ≥10% or death 
over 52 weeks [R15-1220].This will be done primarily within patients randomised to 12 
weeks placebo treatment, since placebo treatment is expected not to impact change in 
extracellular matrix (ECM) biomarkers CRPM, C1M and C3M over 12 weeks nor disease 
progression which will facilitate interpretation of obtained results. 
Additionally, a further secondary objective will be to assess how nintedanib treatment during 
the first 12 weeks of the trial affects the association between change in extracellular matrix 
(ECM) biomarkers CRPM, C1M and C3M over 12 weeks and disease progression. The 
corresponding analyses will comprise all patients treated with nintedanib including patients
who are initially on placebo.
Analyses related to both primary and secondary objectives need to be considered as a whole 
in order to understand the complex network of associations between biomarkers, their change 
over time, the potential impact of treatment and the ultimate outcome of disease progression.
Further objectives are to assess the effect of nintedanib on rate of change in additional ECM 
turnover biomarkers and (based on the main and secondary objective) the predictive value of 
the corresponding rate of change for disease progression. Furthermore, the trial will evaluate 
changes in pulmonary function over time using home and standard in clinic spirometry and 
their correlation. 
BENEFIT - RISK ASSESSMENT
2.3
The favourable benefit-risk ratio based on the so far acquired knowledge about nintedanib is 
the rationale to conduct further studies with nintedanib in idiopathic pulmonary fibrosis.
As described in Section 1, patients with IPF, including patients with only limited FVC 
impairment, may benefit from lesser decline in lung function and hence slower disease 
progression as a result of treatment with nintedanib [P15-09946]. In addition, nintedanib 
significantly reduced the risk of first acute exacerbation in 2 out of 3 clinical trials [P11-
11216, P14-07514].

Two thirds of the patients in this trial will be treated with placebo for the first 12 weeks of the 
trial. A 1:2 randomization (nintedanib:placebo) increases the number of patients treated with 
placebo during the first 12 weeks and consequently increases the power of assessing the
association between change in the extracellular matrix (ECM) biomarker CRPM over 12 
weeks and disease progression in placebo treated patients.  Change in the extracellular matrix 
(ECM) biomarker CRPM over 12 weeks will be classified as stable or falling [≤ 0 
ng/ml/month] or rising [> 0 ng/ml/month] in line with the PROFILE cohort [R15-1220]. A 12 
week placebo period is considered acceptable given that the in- and exclusion criteria assure 
inclusion of patients with mostly preserved lung function at baseline. In addition, it is unclear 
if patients would even receive antifibrotic treatment as in clinical practice. IPF patients with 
limited lung function impairment might not be reimbursed in some countries depending on a 
FVC % predicted threshold (e.g. >80%predicted).
Following the 12 week placebo controlled period all patients in this trial will continue further 
treatment with nintedanib. This will allow active treatment also to patients previously on 
placebo. In the subgroup of patients by baseline FVC (>80% versus ≤ 80% predicted) in the 
pooled INPULSIS data set, the risk of disease progression (time to FVC decline >10% or 
death) up to 12 weeks was low and similar in patients treated with placebo and nintedanib 
(approximately 10% of patients, respectively), although there was a risk reduction in favour 
of nintedanib by approx. 40% in the end of the 52 week treatment period for both subgroups 
and a consistent effect on reducing the annual rate of decline by 50%, similar to the primary 
outcome in the overall population [P15-09946].
The risks of treatment with nintedanib are described in Section 1.2. The most common side 
effects of nintedanib are of gastrointestinal nature (diarrhea, nausea, vomiting, abdominal 
pain), as well as liver enzyme elevations.
Safety monitoring in this trial will consist of regular visits to the investigational site, timely 
blood analyses and specific monitoring procedures to follow-up potential hepatic enzyme 
elevation (potential for drug-induced liver injury), see also Section 5.3.6.1.
In case of lack of tolerability, symptomatic treatment, dose adjustments and/or interruptions 
of trial drugs (at the discretion of the investigator) should be considered to allow for 
resolution of the symptoms (Section 4.2.1).
Based on the mode of action of nintedanib, especially on the inhibition of VEGF or VEGF 
receptors, arterial hypertension, gastrointestinal perforations, thromboembolism and bleeding 
have been identified as potential risks of nintedanib treatment. Therefore, patients requiring 
full dose concomitant anticoagulation, fibrinolysis or high-dose antiplatelet therapy will be 
excluded from this trial.
The mode of action of nintedanib indicates a high potential for teratogenicity and/or 
embryotoxicity, including fetotoxicity/lethality. In women of childbearing potential receiving 
nintedanib, contraceptive measures must be employed 28 days before treatment initiation, 
during the treatment and for a period of 3 months after last drug intake.
Overall, the clinical safety profile of nintedanib as established during the development 
programs including patients with less advanced disease is interpreted as favourable for the 
intended indication of IPF.

After signing the informed consent (prior to any trial related procedures including any 
medication washout), the HRCT scan and surgical lung biopsy sample (later if available) will 
be sent for central review. Screening visit (Visit 1) should only be performed after the 
diagnosis of IPF has been confirmed by the central review. The screening period, i.e. period 
between Visit 1 and 2 should last from 14 days (2 weeks) to a maximum of 28 days (4 
weeks).
Patients whose central lab results are available and who meet all inclusion and none of the 
exclusion criteria may be randomised into the 12-week, double-blind treatment period in 
which they will be receiving either of two possible treatments:  nintedanib of total daily dose 
300 mg administered twice daily, 150 mg in the morning and 150 mg in the evening or 
equivalent placebo bid in double-blind fashion. The chance of receiving either of the above 
mentioned treatments will be 1 (active treatment): 2 (placebo). Randomisation will be 
performed using an Interactive Response Technology System (IRT). Following the 
randomised, double blind, placebo controlled treatment period, all patients will enter the 
single arm, open label, active treatment period of 40 weeks. All patients previously receiving 
placebo will start taking nintedanib. During the trial patients will be returning to the clinic for 
the visits as per Flow Chart for the assessment of efficacy and safety parameters as well as
assessment of compliance with the study drug. 
Dose adjustment visits may occur at any time to manage adverse events. Permanent or 
intermittent dose reduction to a total daily dose of nintedanib 200 mg, i.e. 100 mg bid and 
drug interruptions are allowed to manage AEs as described in Section 4.2.1. Re-escalation to 
nintedanib 150 mg bid is allowed as described in Section 4.2.1. Each time a dose reduction or 
re-escalation is made, the patient must return for an unscheduled visit.
Upon completion of the 52 week treatment period (12 weeks Part 1 and 40 weeks Part 2), 
patients will enter a 28 day (4 week) Follow-Up period. Each patient will attend a total of 12
scheduled visits (Visit 0 and Visits 1 to 11 scheduled as per Flow Chart). Patients, who 
prematurely and permanently discontinue study treatment prior to 52 weeks, will be asked to 
return to the clinic and attend all visits as originally planned per protocol Flow Chart.
Each patient’s participation in the trial is estimated to last a total of approximately 58 weeks.
Depending on patient's informed consent, a blood sample for pharmacogenetics should be 
drawn at Visit 2 or at any subsequent visit from any randomised patients who received at 
least one dose of trial medication.
For an overview plan of procedures please refer to the Flow Chart at the beginning of this 
protocol.
Adverse events will be collected, documented and reported from the time the patient signs an 
Informed Consent up until 28 days after the last dose of study medication.

to patients during treatment period. The ability to unblind will be available via the IRT.
Relevant documentation on the participating (Principal) Investigators and other important 
participants will be filed in the trial master file (TMF) in accordance with BI SOPs
DISCUSSION OF TRIAL DESIGN, INCLUDING THE CHOICE OF 
3.2
CONTROL GROUP(S)
Patients with idiopathic pulmonary fibrosis having a FVC of at least 80% of the predicted
normal value at baseline will be eligible for participation in this trial. It is considered 
acceptable in this patient population to include a 12 week placebo-controlled treatment phase 
(refer to Section 2.3) in order to compare the effect of nintedanib versus placebo on change in 
ECM biomarker turnover.
In the PROFILE study [R15-1220], these biomarkers have shown their predictive potential 
for disease progression as early as after the period of 3 months.
A 1:2 randomisation (nintedanib:placebo) increases the number of patients treated with 
placebo during the first 12 weeks and consequently increases the power of assessing the
association between change in the extracellular matrix (ECM) biomarker CRPM over 12 
weeks and disease progression in placebo treated patients.  Change in the extracellular matrix 
(ECM) biomarker CRPM over 12 weeks will be classified as stable or falling [≤ 0 
ng/ml/month] or rising [> 0 ng/ml/month] in line with the PROFILE cohort [R15-1220].
Fibrotic remodelling of the lung interstitial tissue with subsequent restrictive ventilatory 
defect represents the core element of the histopathology of IPF. Therefore, FVC decline is 
considered a marker of disease progression and will be assessed via supervised spirometry at 
regular clinic visits as well as via home spirometry. Home spirometry may allow a more 
sensitive estimate of lung function decline based on more points of measurement resulting in 
higher accuracy and/or less variability in calculating the slope. Consequently, this study will 
also provide the opportunity to compare changes in FVC over the course of the study using 
standard clinic spirometry compared to home measurements, i.e. generate data on the general 
feasibility and validity of home spirometry in IPF.

After 12 weeks of double-blind treatment, all patients will enter the 40 week single active 
arm phase of the trial to potentially benefit from nintedanib treatment. Total treatment 
duration of 52 weeks is considered adequate to assess disease progression and the predictive 
value of ECM biomarker turnover in this patient population.
The most frequent symptoms in patients with IPF are dyspnoea and cough. These symptoms 
substantially reduce the quality of life and cause major restriction in everyday life, as well as 
incapacity in many patients with IPF. Therefore, a number of patient-reported outcome 
instruments (questionnaires) will be used to document the effect of nintedanib on symptoms
(shortness of breath) and patient’s health related quality of life.
The frequency of visits will allow close monitoring of adverse events, as well as control of 
liver enzyme values, consistent with the recommendations of the prescribing information for
nintedanib.
SELECTION OF TRIAL POPULATION

TREATMENTS
TREATMENTS TO BE ADMINISTERED
4.1
Patients will be randomised 1:2 to 300 mg nintedanib daily (i.e. one capsule of nintedanib 
150 mg in the morning and one capsule of nintedanib 150 mg in the evening) or matching 
placebo (i.e. one capsule of matching placebo in the morning and one in the evening) during 
the first 12 weeks of the treatment period. For the subsequent 40 weeks all randomised 
patients will enter the single active arm treatment. All patients previously receiving placebo 
will start taking nintedanib.
During the trial, permanent or intermittent dose reduction to a total daily dose of nintedanib 
200 mg, i.e. 100 mg bid and intermittent drug interruptions are allowed to manage AEs as 
described in Section 4.2.1. Re-escalation to nintedanib 150 mg bid is also allowed as 
described in Section 4.2.1.
Trial medication will be provided as a medication kit. One medication kit will contain seven 
blister cards each containing 10 soft gelatin capsules of either blinded nintedanib 150 mg, or 
blinded nintedanib 100 mg, or matching placebo (for blinded part of the trial) and open label 
nintedanib 150 mg, or open label nintedanib 100 mg (for the open label part) thus allowing 
sufficient amount of medication for approximately one month.  Sufficient amount of kits, 
each identified with a unique medication number, will be dispensed to each patient 
throughout the trial via IRT. No active comparator is used in this trial.
Trial medication is manufactured by Boehringer Ingelheim.

Method of assigning patients to treatment groups
To guarantee the double-blind design of the study, all treatments will be indistinguishable for 
the patient as well as for the investigator.
After final assessment of all inclusion and exclusion criteria, each eligible patient will be 
randomly assigned in 1:2 ratio (treatment: placebo) to one of the two treatment options at 
Visit 2 (double blind phase applicable to the first 12 weeks only). An interactive voice 
response system (IRT) will be used for randomisation to a specific treatment group in this 
trial and for the appropriate supply and re-supply of study medication to patients throughout 
the trial. Patients will be randomised to receive either an active drug at a dosage of 150 mg 
bid or matching placebo. 
Documents such as but not limited to user guides, instructions, worksheets on the IRT will be 
stored in the ISF.
Note that the medication number is different from the patient number (the latter one is 
assigned after the informed consent process has been completed).

4.1.3
Selection of doses in the trial
A dose of nintedanib 150 mg bid (total daily dose of 300 mg) was selected for this trial as this 
is the recommended dose based on prescribing information in participating countries as well 
as the dose that has shown to be efficacious in two replicate phase III trials. 
Dose adjustments are permitted as per Section 4.2.
4.1.4
Drug assignment and administration of doses for each patient
Drug assignment
Dosage for an individual patient will be assigned by means of an IRT at Visit 2. Patients
will be randomised to receive either an active drug at a dosage of 150 mg bid or matching 
placebo.
At Visit 5, all patients will start receiving open label nintedanib for the remainder of the trial.  
Patients previously receiving placebo will now start receiving nintedanib. All patients will 
remain on the same dose they were previously receiving unless prescribed otherwise by the 
investigator. Patients, site staff and trial team will remain blinded to patient’s previously 
randomised treatment group.
Study treatment will comprise of 1 capsule twice daily throughout the trial (refer to Section 
4.1). Treatment kits containing 4 weeks + 1 week reserve treatment (one treatment kit 
containing 7 blister cards each having 10 capsules) will be dispensed to the patients.  
To ensure patients receive adequate supply of study medication, kits will be dispensed at 
clinic visits in quantities outlined in Table 4.1.4: 1. Unscheduled re-supplies with additional 
medication kits will be possible via the IRT.

The investigational product should only be dispensed to participating patients according to 
the protocol by authorised personnel as documented on the Investigator’s Trial Staff List. All 
unused medication must be returned to the Sponsor. Receipt, usage and return must be 
documented on the respective forms. Any discrepancies must be accounted for.
Drug administration
•
Study drug will be administered orally on a twice daily basis (bid). At all clinic visits 
the study drug will be administered at the study site (after any sampling 
procedures and PFTs). The patients should swallow the study medication unchewed 
together with a glass of water (~250 mL), and should observe a dose interval of 
approximately 12 hours. Study drug needs to be taken at approximately the same time 
every day (preferably between 06:00 and 11:00 in the morning, and between 18:00 
and 23:00 in the evening). 
•
Because nintedanib may cause stomach discomfort, it is recommended to take the 
administered drug after the meal. 
•
If a dose of nintedanib is missed, i.e. not taken between 06:00 and 11:00 in the 
morning, and between 18:00 and 23:00 in the evening, administration should resume 
at the next scheduled time at the recommended dose. No catch up of missed doses is 
permitted.
Patients experiencing adverse effects requiring temporary drug discontinuation (refer to 
Section 4.2.1 and 4.2.2) may start to receive study drug at 100 mg bid. The dose can also be 
reduced without prior discontinuation, i.e. immediately stepping down from 150 mg bid to 
100 mg bid if necessary. In the case of severe toxicity or when the reduced dose is again not 
tolerated, drug treatment must be stopped and cannot be restarted. All dose reductions must 
be approved by the Investigator or delegated site staff at the site (during the scheduled or 
unscheduled visit) and the reason for reduction must be documented.  
In case of adverse events requiring dose reduction (refer to Sections 4.2.1 and 4.2.2), 100 mg 
bid (or matching placebo) will be assigned by IRT upon call of the Investigator. The colour 
of the 150 mg capsules and the 100 mg capsules will be slightly different; the packaging will 
remain the same (same number of capsules per blister, same number of blisters per box).  
If the reduced dose is well tolerated, re-escalation to 150 mg bid is possible, according to 
procedures described in Section 4.2.1.1. 
The amount of study drug dispensed at the time of dose reduction and dose re-escalation is 
dependent upon the amount of time between the unscheduled visit and the next planned study 
visit.  Therefore at unscheduled visits for dose reductions and dose re-escalations, IRT will 
assign only the number of boxes of study medication needed until the next predicted planned 
patient visit as noted within the IRT system.

Blinding and procedures for unblinding
Blinding
4.1.5.1
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 randomised treatment 
assignments until after database lock.
The randomisation code will be kept secret by Clinical Trial Support up to database lock.
Unblinding and breaking the code
4.1.5.2
Emergency unblinding will be available to the Investigator / Pharmacist / investigational drug 
storage manager 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 assure safety of trial participants. The reason for unblinding must be 
documented in the source documents and/or appropriate CRF page along with the date and 
the initials of the person who broke the code.
Due to the requirements to report Suspected Unexpected Serious Adverse Reactions
(SUSARs), it may be necessary for a representative from Boehringer Ingelheim’s
Pharmacovigilance group to access the randomisation code for individual patients during trial
conduct. The access to the code will only be given to authorised Pharmacovigilance
representatives and not be shared further.
4.1.6
Packaging, labelling, and re-supply
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 local clinical monitor 
(as provided in the list of contacts) must be contacted immediately.
All used and unused trial medication must be returned to the sponsor. Receipt, usage and 
return must be documented on the respective forms. Account must be given for any 
discrepancies.

reconcile all investigational products received from the Sponsor. At the time of return to the 
Sponsor and/or appointed CRO, the Investigator / Pharmacist / investigational drug storage 
manager 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.
CONCOMITANT THERAPY, RESTRICTIONS, AND RESCUE 
4.2
TREATMENT
4.2.1
Rescue medication, emergency procedures, and additional treatment(s)
Rescue medication to reverse the action of nintedanib is not available.
Recommendations for managing adverse events (exceptions include diarrhea 
4.2.1.1
and liver enzyme elevations)
•
If a patient experiences adverse events considered related to the trial medication,
symptomatic treatment should be initiated (e.g. anti-emetic treatment such as 
dimenhydrinat if appropriate). 
•
Patients experiencing adverse events considered related to nintedanib may require 
drug interruption or reduction of dose (at the discretion of the investigator) to allow 
for resolution of symptoms.

Recommendations for management of diarrhea
4.2.1.2
The Common Terminology Criteria for Adverse Events (CTCAE Version 4.0) grading will 
be used to grade the severity of all AEs and SAEs of diarrhea. Management 
recommendations for diarrhea are based on the CTCAE grades.
In general, diarrhea should be managed as early as possible after onset of first symptoms with 
standard antidiarrheal symptomatic treatment, e.g. loperamide.
The medical judgement should be used in decision of the use preventive treatment with 
loperamide after the first episode of diarrhea.  
If diarrhea persists despite optimal symptomatic treatment, treatment interruption (for a 
maximum of 4 weeks) and dose reduction of nintedanib should be considered based on the 
recommendations described in Table 4.2.1.2: 1

Restrictions regarding women of childbearing potential 
4.2.2.3
The anti-angiogenic properties of nintedanib indicate a high potential for teratogenicity 
and/or embryotoxicity, including fetotoxicity/lethality. In women of childbearing potential 
receiving nintedanib, contraceptive measures must be employed 28 days before treatment 
initiation, during the trial and for a period of 3 months after last drug intake.
TREATMENT COMPLIANCE
4.3
The Investigator will maintain accurate records of receipt of all study medication, including 
dates of receipt. In addition, accurate records will be kept regarding when and how much of 
each study medication is dispensed to, and used by each individual patient in the study. 
Reasons for deviating from the expected dispensing regimen must be recorded. A Drug 
Accountability Form, provided for this purpose, will be signed by the Investigator or delegate 
at the conclusion of the study. At the completion of the study, in order to satisfy regulatory 
requirements regarding drug accountability and destruction, all used and unused packages 
must be returned to the Sponsor or its designee. 
Patients are requested to bring all remaining trial medication including empty package 
material with them when attending visits.
Based on capsule counts, treatment compliance will be calculated as the number of capsules 
taken, divided by the number of capsules which should have been taken according to the 
scheduled period, multiplied by 100. A compliance worksheet will be provided in the ISF. 
Treatment compliance (%) =
Number of capsules actually taken 100
     Number of capsules which should have been 
taken
If the number of doses taken is not between 80-120% without identified cause like AE or 
consent withdrawal, site staff will explain to the patient the importance of treatment 
compliance. 
Compliance will be verified by the on-site monitor authorised by the Sponsor.

VARIABLES AND THEIR ASSESSMENT 
TRIAL ENDPOINTS
5.1
Note that all endpoints based on spirometry are measured by clinic spirometry unless 
explicitly stated otherwise.
5.1.1
Primary Endpoint
The primary endpoint is the rate of change (slope) in blood CRPM from baseline to week 12.
5.1.2
Secondary Endpoints
The key secondary endpoint is the proportion of patients with disease progression as defined 
by absolute FVC (% predicted) decline ≥10% or death until week 52 based on in clinic 
supervised spirometry.
Secondary endpoints are the rate of change (slope) in blood C1M from baseline to week 12 
and the rate of change (slope) in blood C3M from baseline to week 12.

ASSESSMENT OF EFFICACY
5.2
Measurements of biomarkers
Blood samples collected from patients at visits will allow measurement of following 
concentrations: 
 collagen 1 degraded by MMP-
2/9/13 (C1M), collagen 3 degraded by MMP-9 (C3M),
 C-reactive protein degraded by MMP-1/8 (CRPM), and citrullinated vimentin
Sample collection is described in Section 5.5. More details of sample collection and 
processing will be given in a lab manual.
Measurements of in clinic FVC
Spirometry devices for in clinic measurements as well as devices for home spirometry will be 
supplied by a central vendor to all participating sites.
In clinic spirometry performance will be centrally reviewed. On-going feedback and training 
will be provided. Predicted normal values shall be calculated according to ECSC [R94-1408].
The spirometers and their use, including daily calibration, must meet ATS/ ERS criteria (P05-
12782). Spirometry will be conducted while the patient is in a seated position. The test will 
be done in triplicate and selection of the best result done according to the guidelines. 
Spirometric results will be electronically transmitted and confirmed by central reading.
Further details on in clinic spirometry shall be provided in the ISF.
For each patient, pulmonary function testing will always start at approximately the same time 
of the day within ±90 minutes maximum difference from measurement time at Visit 1. 
On days of clinic visits (including the screening visit), patients must refrain from strenuous 
activity at least 12 hours prior to pulmonary function testing.

Smoking should be discouraged throughout the study day (clinic visit) and will not be 
permitted in the 30-minute period prior to spirometry. Patients should also avoid cold 
temperatures, environmental smoke, dust, or areas with strong odours (e.g. perfumes).
Washout of bronchodilators (betamimetics and anticholinergics) need to be observed prior to 
in clinic spirometry (8 hours for short acting and 24 hours for long acting bronchodilators). 
 
 
 
 
 
 
 
 
 
Carbon Monoxide Diffusion Capacity and Oxygen Saturation.
The site will use its own carbon monoxide diffusion capacity (DLCO) equipment and 
conduct all measurements with the same equipment (e.g. if several devices would be 
available at the site). Single-breath DLCO will be carried out according to the ATS / ERS 
guideline on DLCO measurements [R06-2002]. Before beginning the test, the manoeuvers 
should be demonstrated and the subject carefully instructed. Please refer to Appendix 10.5 for 
additional information. The DLCO assessment should be performed after the FVC 
assessment.
Oxygen saturation (SpO2) will be measured at rest by standard pulse oximetry (unaffected 
skin of earlobe or fingertip or forehead) and the recorded value will be entered in eCRF.
 
ASSESSMENT OF SAFETY

findings or worsening of baseline conditions detected at the subsequent physical 
examinations will be recorded as adverse events on the appropriate eCRF page.
5.3.2
Vital Signs
Vital signs including measurements of systolic and diastolic blood pressure and pulse rate, 
will be measured with the patient seated after having rested for at least 5 minutes at each on 
site visit.
5.3.3
Safety laboratory parameters
The laboratory tests will include:
•Haematology: complete blood count with platelet count and automated differential.
•Chemistry: sodium, potassium, creatinine, creatinine clearance calculated by 
Cockcroft–Gault formula, aspartate aminotransferase (AST), alanine transaminase 
(ALT), gamma-glutamyl transferase  (GGT), total protein, alkaline phosphatase 
(ALP), total bilirubin, lactate dehydrogenase (LDH), creatinine kinase and thyroid 
stimulating hormone (TSH).
•Coagulation: International normalized ratio (INR) and partial thromboplastin time 
(PTT).
•Urine: pregnancy testing 
If laboratory values indicate toxicity, adequate and more frequent blood sampling will be 
performed at the discretion of the investigator.
Laboratory analysis during main visits will be done using central laboratory services. Venous 
whole blood will be collected in appropriate syringes provided by the sponsor through the 
assigned central laboratory. No fasting is required. Details regarding centrifuge, processing, 
storage and shipment of samples will be determined by the central laboratory in accordance 
with the sponsor. The investigators will be informed and instructed by the central laboratory 
and detailed documentation will be included in the ISF.
In case of liver enzymes elevation, close monitoring must be ensured by the investigator 
(Section 4.2.1.3).
5.3.4
Electrocardiogram
12-lead ECGs are to be conducted with site equipment as specified in the Flow Chart. 
Changes should be examined, compared to previous test, and assessed for clinical relevance. 
Clinically relevant findings at Visit 1 will be recorded as baseline conditions, new abnormal 
findings thereafter will be recorded as adverse events.

Other safety parameters
Medical history
All active and relevant historical disorders will be recorded on the Medical History/Baseline 
Conditions eCRF page at the screening visit (Visit 1).
A patient diary will be used by all patients in this trial. The diary will be used to prompt 
patient recollection during adverse event, concomitant therapies and times of drug intake 
three days prior to the PK sampling. Instructions for use of the diary will be provided in the 
ISF.
5.3.6
Assessment of adverse events
Definitions of AEs 
5.3.6.1
Adverse event
An adverse event (AE) is defined as any untoward medical occurrence in a patient or clinical 
investigation 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 unfavourable and unintended sign (including an abnormal 
laboratory finding), symptom, or disease temporally associated with the use of a medicinal 
product, whether or not considered related to the medicinal product.
Adverse reaction
An adverse reaction is defined as a response to a medicinal product which is noxious and
unintended. Response in this context means that a causal relationship between a medicinal
product and an adverse event is at least a reasonable possibility. Adverse reactions may arise
from use of the product within or outside the terms of the marketing authorisation or from
occupational exposure. Conditions of use outside the marketing authorization include off-
label use, overdose, misuse, abuse and medication errors.
Serious adverse event
A serious adverse event (SAE) is defined as any AE which:

results in death,

is life-threatening,

requires inpatient hospitalisation or prolongation of existing hospitalisation,

results in persistent or significant disability or incapacity,

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 judgment which may jeopardize the patient and may

require medical or surgical intervention to prevent one of the other outcomes listed in 
the above definitions. Examples of such events are intensive treatment in an 
emergency room or at home for allergic bronchospasm, blood dyscrasias or 
convulsions that do not result in hospitalisation or development of dependency or 
abuse. Any suspected transmission via a medicinal product of an infectious agent is 
considered a serious adverse reaction.
Life-threatening in this context 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.
For Japan only: 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.
AEs considered “Always Serious”
Cancers of new histology and exacerbations of existing cancer must be reported as a serious 
event regardless of the duration between discontinuation of the drug and the occurrence of the 
cancer.
In accordance with the European Medicines Agency initiative on Important Medical Events, 
Boehringer Ingelheim has set up a list of further AEs, which by their nature, can always be 
considered to be “serious” even though they may not have met the criteria of an SAE as given 
above.
The latest list of “Always Serious AEs” can be found in the RDC system. These events 
should always be reported as SAEs as described in Section 5.3.7.
Adverse events of special interest (AESIs)
The term AESI relates to any specific AE that has been identified at the project level as being 
of particular concern for prospective safety monitoring and safety assessment within this trial, 
e.g. the potential for AEs based on knowledge from other compounds in the same class. AESI 
need to be reported to the Sponsor’s Pharmacovigilance Department within the same 
timeframe that applies to SAE, see Section 5.3.7.
The following are considered as AESIs: adverse events relating to gastrointestinal perforation 
and hepatic injury.
Hepatic Injury
In this study protocol, hepatic injury is defined as follows:

ALT and/or AST ≥ 8 fold ULN

ALT and /or AST ≥ 3 fold ULN and total bilirubin ≥ 2 fold ULN*

ALT and /or AST ≥ 3 fold ULN and unexplained INR > 1,5*

ALT and /or AST ≥ 3 fold ULN and unexplained eosinophilia (>5%)*

ALT and /or AST ≥ 3 fold ULN and appearance of fatigue, nausea, vomiting, right 
upper abdominal quadrant pain or tenderness, fever and/or rash
* in the same blood draw sample.

These lab findings constitute a hepatic injury alert and the patients showing these lab 
abnormalities need to be followed up according to the “DILI checklist” provided in the ISF.
In case of clinical symptoms of hepatic injury (icterus, unexplained encephalopathy, 
unexplained coagulopathy, right upper quadrant abdominal pain, etc.) without lab results 
(ALT, AST, total bilirubin) available, the investigator should make sure these parameters are 
analysed, if necessary in an unscheduled blood test. Should the results meet the criteria of 
hepatic injury alert, the procedures described in the DILI checklist should be followed.
Intensity of AEs
The intensity of the AE should be judged based on the following:
Mild:
Awareness of sign(s) or symptom(s) that is/are easily tolerated
Moderate:
Enough discomfort to cause interference with usual activity
Severe:
Incapacitating or causing inability to work or to perform usual activities
The intensity of diarrhea adverse events should in addition be classified and recorded in the 
(e)CRF according to the Common Terminology Criteria for Adverse Events (CTCAE)
version 4 [R10-4848].
Table 5.3.6.1:1
CTCAE Categorization for diarrhea
CTCAE Grade
1
Increase of <4 stools per day over baseline
2
Increase of 4 to 6 stools per day over baseline
3
Increase of ≥7 stools per day over baseline; incontinence
4
Life threatening consequences
5
Death
Causal relationship of AEs
The definition of an adverse reaction implies at least a reasonable possibility of a causal 
relationship between a suspected medicinal product and an adverse event. An adverse 
reaction, in contrast to an adverse event, is characterised by the fact that a causal relationship 
between a medicinal product and an occurrence is suspected.
Medical judgment should be used to determine the relationship, considering all relevant 
factors, including pattern of reaction, temporal relationship, de-challenge or re-challenge, 
confounding factors such as concomitant medication, concomitant diseases and relevant 
history.
Arguments that may suggest that there is a reasonable possibility of a causal relationship

• 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 aetiologies that could explain the event (e.g. 
preexisting 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 diminished).
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; 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 study drug treatment continues or 
remains unchanged.
For Japan only: The reason for the decision on causal relationship for unlisted AEs needs to 
be provided in the eCRF.
5.3.7
Adverse event collection and reporting
AE Collection
The Investigator shall maintain and keep detailed records of all AEs in their patient files.
The following must be collected and documented on the appropriate CRF(s) / eCRF by the 
Investigator:
•
From signing the informed consent onwards through the Residual Effect Period 
(REP), until individual patient’s end of trial:
-all AEs (serious and non-serious) and all AESIs.
However, if an individual patient discontinues trial medication prematurely but
stays in the trial (i.e. if further visits incl. telephone visits, or vital status assessments are 
planned) from then on and until the individual patient’s end of the trial the Investigator 
must report related SAEs and related AESIs.

•
After the individual patient’s end of trial: 
the investigator does not need to actively monitor the patient for AEs but should only
report relevant SAEs and relevant AESIs of which the investigator may become aware 
of.
The Residual Effect Period (REP) is defined as 28 days after the last trial medication 
application. All AEs which occurred through the treatment phase and throughout the REP 
will be considered as on treatment please see Section 7.3.4. Events which occurred after the 
REP will be considered as post treatment events.
AE reporting to sponsor and timelines
The Investigator must report SAEs, AESIs, and non-serious AEs which are relevant for the 
reported SAE or AESI, 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.
For Japan only: All SAEs must be reported immediately to the head of the trial site.
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.
Information required
For each AE, the Investigator should provide the information requested on the appropriate 
(e)CRF pages and the BI SAE form. The Investigator should determine the causal 
relationship to the trial medication.
The following should also be recorded as an (S)AE in the (e)CRF and SAE form (if 
applicable):
Worsening of the underlying disease or of other pre-existing conditions

Changes in vital signs, ECG, physical examination and laboratory test results, if they 
are judged clinically relevant by the Investigator.
If such abnormalities already pre-exist prior trial inclusion they will be considered as 
baseline conditions.
All (S)AEs, including those persisting after individual patient’s end of trial must be followed 
up until they have resolved, have been sufficiently characterized, or no further information 
can be obtained.
Pregnancy
In rare cases pregnancy may occur in a clinical trial. Once a patient has been enrolled into
this clinical trial and has taken trial medication, the Investigator must report immediately
(within 24 hours) a potential drug exposure during pregnancy (DEDP) to the sponsor’s
unique entry point (country-specific contact details will be provided in the ISF). The
Pregnancy Monitoring Form for Clinical Trials (Part A) should be used.
The outcome of the pregnancy associated with the drug exposure during pregnancy must be 
followed up and reported to the Sponsor’s unique entry point on the Pregnancy Monitoring 
Form for Clinical Trials (Part B). 
The ISF will contain the Pregnancy Monitoring Form for Clinical Trials (Part A and B).
As pregnancy itself is not to be reported as an AE, in the absence of an accompanying SAE
and/or AESI, only the Pregnancy Monitoring Form for Clinical Trials and not the SAE form 
is to be completed. If there is an SAE and/or AESI associated with the pregnancy an SAE
form must be completed in addition.

ASSESSMENT OF EXPLORATORY BIOMARKER(S)
5.5
Blood samples will be taken according to the Flow Chart for the analysis of exploratory 
biomarkers. 
These samples will be stored for up to 3 years after the end of the clinical trial.
Samples will be shipped from the sites to a central laboratory for short-term storage. These
samples will be shipped in batches from the central laboratory to Boehringer Ingelheim or to
another location for biomarker analyses or long-term storage.
In order to better understand the effects of nintedanib on the disease, mechanistic and disease 
related biomarkers will be assessed in peripheral blood of randomised patients.
The assessment of exploratory biomarkers is a key feature of this clinical trial with the aim to 
better characterise and understand the disease, as well as their potential predictive value for 
treatment response. All biomarkers related to IPF pathology will be explored pre during and
post treatment with nintedanib or placebo in serum and plasma and will be correlated with the 
clinical endpoints.

Serum banking
To enable future not yet specified biomarker analyses additional blood will be collected into 
serum collection tubes. This sample will be collected according to the Flow Chart. Details on 
sample collection and processing will be given in the ISF. This sample will be stored up to 15 
years after the end of the trial and may be used for further characterization of IPF patients.
Approximately 100 mL of blood will be collected for serum banking.  Detailed instructions 
for serum banking sampling, handling and shipment of samples are provided in the ISF.
DNA banking
The DNA sample derived from the original blood sample will be stored by Boehringer
Ingelheim for up to 15 years after the end of the clinical trial or until there is no more 
material available for tests. The stored DNA may be used at a later time for 
pharmacogenomic analyses.  
Methods and timing of DNA banking sample collection
An amount of approximately 8.5 mL blood will be collected per PaxGene DNA blood 
sampling tube for those patients who signed a separate informed consent concerning the
Sample DNA banking part with any other blood sampling after randomisation. The Paxgene 
Blood DNA tubes can be stored and shipped at room temperature within 14 days. If a longer 
storage and shipment period for Paxgene Blood DNA tubes is necessary, the blood samples 
have to be stored at a temperature of approximately -20°C or below.
Once frozen, thawing of the samples should be avoided except for analysis.
Detailed instructions for pharmacogenomics sampling, handling and shipment of samples are
provided in the ISF.

INVESTIGATIONAL PLAN
VISIT SCHEDULE
6.1
This trial starts with Visit 0 during which informed consent process shall be undergone 
HRCT scans and biopsies (later if available) shall be sent for central review to confirm the 
diagnosis of IPF. Further the trial consists of screening visit (Visit 1) and screening period
lasting 14 days (2 weeks), treatment period lasting 52 weeks and follow-up period lasting 28 
days (4 weeks). The treatment period will consist of two parts. At Visit 2 patients will be 
randomised into double-blind portion of the study. Additional clinic visits of the double blind 
period will be scheduled at week 4, 8 and 12 (Visits 3, 4 and 5). At Visit 5, i.e. after 
completing the randomised, double blind treatment all patients will enter the single arm, open 
label, active treatment period. During this period patients will visit the clinic for scheduled 
visits at week 16, 20, 24, 36 and 52 (Visits 6, 7, 8, 9 and 10). The follow-up visit (Visit 11) 
will be scheduled 28 days post-treatment. Unscheduled visits may be conducted anytime if 
deemed necessary.
Time windows to be adhered to for scheduling of visits are shown in the Flow Chart. Sites 
should make every attempt to adhere to the protocol time windows as close as possible. The 
screening period (between Visit 1 and Visit 2) may be extended by additional 2 weeks (i.e. 28 
day total) for any reasons (e.g. exacerbation, lab results receipt, etc.). All onsite visits from 
Visits 1 to Visit 11 will be scheduled in the morning, in order to guarantee start of pulmonary 
function testing at approximately the same time of the day (recommended time for PFTs from 
8:00 till 11.00 a.m.; any subsequent PFTs should preferably be done within ± 90 minutes 
from the measurement at Visit 1). Patients should make every attempt to complete the study 
as specified. Investigators should encourage patient treatment compliance and adherence to 
other protocol specific activities.
All deviations from the planned visit schedule will be documented. 
Rescheduling prior to randomisation.
• if a patient experiences acute IPF exacerbation or respiratory tract infection between Visit 0 
and Visit 1, the Visit 1 will be postponed until complete recovery from the infection or 
exacerbation, preferably 4 weeks following the recovery from the infection or exacerbation.
• laboratory parameters found abnormal at visit 1 may be re-tested once prior to Visit 2.
• if the screening period (2 weeks and 2 additional weeks for administrative reasons) needs to 
be extended further (counted from Visit 1), the clinical monitor should be contacted.
Reasoned prolongation of the screening period may be allowed by the clinical monitor.
• if a patient experiences an IPF exacerbation or respiratory tract infection during the 
screening period (2 weeks) between Visit1 and Visit 2, the Visit 2 will be postponed until 
complete recovery from the infection or exacerbation, preferably 4 weeks following the 
recovery from the infection or exacerbation.
Patients should make every attempt to adhere to the protocol. Investigators should encourage 
patient treatment compliance and adherence to other protocol related activities.
Subsequent visits should always be planned to take place at scheduled dates in line with the 
protocol Flow Chart.

future visits as planned, any attempt will be made to get information on vital status at Week 
52 (refer to Flow Chart).
Patients will be asked to agree to be contacted by the site personnel, which could be by 
telephone calls, to allow collection of this information.
If death occurs, the investigator will review the circumstances, including the relevant medical 
records to ascertain the most likely primary and secondary causes of death.
Collection of vital status will be performed in accordance with national ethical and regulatory 
guidelines. The need for vital status information will be explained to patients prior to their

STATISTICAL METHODS AND DETERMINATION OF
SAMPLE SIZE
STATISTICAL DESIGN - MODEL
7.1
This is a randomised, placebo controlled, multi-centre, multinational, prospective, double 
blind trial to investigate the effect of oral nintedanib 150 mg twice daily on change in 
biomarkers of extracellular matrix (ECM) turnover in patients with idiopathic pulmonary 
fibrosis (IPF) and preserved forced vital capacity (FVC).
The primary endpoint is the rate of change (slope) in blood CRPM from baseline to week 12. 
Therefore, the rate of change (slope) in blood CRPM will be analyzed using random 
coefficient regression (random slopes and intercepts) model including gender, age and height
as covariates.
The secondary endpoint, proportion of patients with disease progression defined by FVC 
decline ≥10% or death, will be analysed using logistic regression models or other appropriate 
methods.
NULL AND ALTERNATIVE HYPOTHESES
7.2
The objective of this study, demonstrating a treatment effect of nintedanib at a dose of 150 
mg bid compared to placebo for the rate of change (slope) in blood CRPM, will be tested 
using the following null hypothesis.
H0: No difference in the rate of change (slope) in blood CRPM evaluated from 
baseline until 12 weeks of treatment between nintedanib mg bid and placebo.
The alternative hypothesis is
Ha: The rate of change (slope) in blood CRPM is different for patients taking 
nintedanib 150 mg bid than those taking placebo.
The hypothesis will be tested using 5% level of significance (two-sided test).

The Randomised set (RS), consists of those patients who were randomised to a
treatment group.
 
 
The efficacy and safety analysis will be conducted on the TS. Efficacy parameters will be 
analysed from an as randomised perspective and safety parameters from an as treated 
perspective, respectively. For efficacy analysis, all measurement performed within the first 12 
weeks will be used. Efficacy evaluations done after lung transplant will not be used for the 
efficacy analyses; sensitivity analyses will be performed including these data.
Although there is no per protocol data set in the study, reasons for important protocol
violations will be specified in the Trial Statistical Analysis Plan (TSAP). Patients with 
potential important protocol violations (those that relate to patient safety or efficacy) will be 
identified at Blinded Review Planning Meetings and listed in the clinical trial report.
7.3.1
Primary endpoint analyses
The primary endpoint is the rate of change (slope) in blood CRPM evaluated from baseline 
over 12 weeks (expressed in ng/mL/month) estimated from measurements taken over 12 
weeks of treatment. The rate of change (slope) in blood CRPM is assumed to be linear within 
each subject over the 12 weeks period. The intercepts and slopes will be assumed to be 
normally distributed with arbitrary covariance matrix. Gender, age and height which are usual 
predictors of FVC will also be included in the model. Baseline blood CRPM will be 
measured at visit 2. No imputation is planned if this assessment is not available for a patient. 
The within patient error will be assumed to be independent and normally distributed with 
mean zero and a common variance. The Kenward-Roger approximation will be used to 
estimate denominators degrees of freedom. Significance tests will be based on least-squares 
means using a two-sided α=0.05 (two-sided 95% confidence intervals). Analyses will be 
implemented using SAS® Version 9.4.
The linearity assumption for the rate of change (slope) in blood CRPM will be tested and 
sensitivity analysis will be done with alternative models described in the Trial Statistical 
Analysis Plan (TSAP). The effect of missing data will be investigated using pattern-mixture 
models. Depending on the pattern of the missingness in the data, multiple imputation 
methods may also be considered.
 
7.3.2
Secondary endpoint analyses
For the key secondary endpoint, proportion of patients with disease progression as defined by 
FVC decline ≥10% or death over week 52, two main analyses are planned. 
Firstly, in order to assess the predictive value of change in extracellular matrix (ECM) 
biomarker CRPM over 12 weeks for disease progression as defined by FVC decline ≥10% or

death over 52 weeks, a logistic regression (or a similar appropriate) analysis including 
baseline blood CRPM and the rate of change (slope) in blood CRPM over the first 12 weeks 
as covariates will be applied for the placebo treated patients only.
Secondly, in order to assess how nintedanib treatment during the first 12 weeks affects the 
association between change in extracellular matrix (ECM) biomarker CRPM over 12 weeks 
and disease progression, a logistic regression (or a similar appropriate) analysis including 
baseline blood CRPM, rate of change (slope) in blood CRPM over the first 12 weeks, 
treatment and treatment CRPM slope interaction as covariates will be applied. The interaction 
term will be of primary interest within this analysis. More details will be given in the TSAP.
Both analyses will be repeated for rate of change (slope) in the biomarkers C1M and C3M 
defined as secondary endpoints. Reasonably, baseline CRPM as covariate will be replaced by 
baseline C1M/C3M in these analyses.
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 residual effect period 
(REP), a period of 28 days 
after the last dose of trial medication, will be assigned to the treatment period for evaluation.
All treated patients will be included in the safety analysis. In general, safety analyses will be 
descriptive in nature and will be based on BI standards. No hypothesis testing is planned.
Statistical analysis and reporting of adverse events will concentrate on treatment-emergent 
adverse events. To this end, all adverse events occurring between start of treatment and end 
of the residual effect period will be considered ‘treatment-emergent’.  The residual effect 
period is defined as 28 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 the Medical 
Dictionary for Drug Regulatory Activities (MedDRA).
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 highlighted in the 
listings. 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.
 
 
 
 
INTERIM ANALYSES
7.4
No interim analysis is planned.
HANDLING OF MISSING DATA
7.5
7.5.1
Efficacy endpoints
In efficacy analyses of continuous endpoints, missing data will not be imputed. In the 
analyses of the time-to-event endpoints, missing or incomplete data are managed by standard 
survival analysis techniques. These will be described in detail in the TSAP.
In the analyses of the categorical endpoints, missing data will be imputed using the worst 
case.

7.5.2
Safety endpoints
Missing or incomplete AE dates will be imputed according to BI standards. With respect to 
other safety evaluations, it is not planned to impute missing values.
 
RANDOMISATION
7.6
Patients will be randomised in blocks to double-blind treatment with an unequal probability 1
to 2 of assignment to nintedanib and placebo. BI will arrange for the randomisation and the 
packaging and labelling of trial medication. The randomisation list will be generated using a 
validated system, which involves a pseudo-random number generator so that the resulting 
treatment will be both reproducible and non-predictable. The block size will be documented 
in the CTR. Access to the codes will be controlled and documented. All members of the 
Medical Project Team will remain blinded to the randomisation schedule until after the final 
database is locked.
DETERMINATION OF SAMPLE SIZE
7.7
The sample size calculations are based on change relative to baseline in biomarker levels of 
serum CRPM, serum C1M and serum C3M (unpublished data, no reference available). The 
sample size calculations are based on two-sided tests (α =0.05) to detect a difference in 
means of two independent samples with a 1:2 randomisation ratio nintedanib:placebo in the 
samples with a power of 90%. No multiplicity adjustments are made as part of the power 
calculation, and no adjustment is made for a potential subject withdrawal. Sample size 
calculations are performed for assumed differences between treatment group and placebo of 
20% and 30% difference. Due to the lack of data from respective IPF patients and since there 
is no evidence biomarker courses are principally different across both indications, data from 
two studies of RA patients are used to estimate the standard deviation over time in biomarker 
values relative to baseline: Study A) RA patients including a placebo group and a treatment 
group with measurements of serum CRPM, serum C1M and serum C3M at baseline, weeks 4, 
16, and 24; and Study B) RA patients including a placebo group and a treatment group with 
measurements of serum CRPM, serum C1M and serum C3M at baseline, weeks 4, and 12.
The hypothesis to be tested can be formulated as:
H0:
µTreatment = µPlacebo
tested confirmatively against the alternative
Ha:
µTreatment    µPlacebo
where µTreatment is the change in biomarker relative to baseline in the treatment group, and 
µPlacebo is the change relative to baseline in the placebo group.

treatment group difference of 20% with a power of 90% with a treatment allocation ratio of 
1:2 (Nintedanib:Placebo).
However, the key secondary endpoint requires more patients for two reasons: firstly, only 
patients initially treated with Placebo are analysed in the first step (reducing the actual sample 
size for this analysis to 2/3 of the total sample size) and secondly, some loss of information is 
associated with the planned analysis due to the binary state of the endpoint. To be more 
precise, with n=350 randomised patients, n=233 patients will be initially treated with Placebo
and based on the INPULSIS results [P14-07514], we expect to observe a total of about 40% 
of disease progression as defined by FVC decline ≥10% or death over week 52 for that 
treatment group. Using available data from the observational PROFILE study [R15-1220], 
we further expect roughly half of the patients to have rising biomarker values (slope greater 
than zero) and the remaining patients having stable biomarker values (slope less or equal to 
zero) resulting in about equally sized groups if the rate of change (slope) in blood CRPM 
from baseline to week 12 is dichotomized. With the stated sample size, an absolute difference 
in rates of at least 20% (i.e. 30% vs 50% of patients with disease progression) can be detected 
with a power of 88%. 
For these reasons, a sample size of n=350 patients (117 on nintedanib and 233 on placebo) is 
planned for this study.

APPENDICES
CRITERIA FOR HRCT/BIOPSY CENTRAL 
10.1
All chest HRCTs, and histopathology slides of surgical lung biopsies (the latter if available) 
will be centrally reviewed.
In the absence of a surgical lung biopsy, chest HRCT must qualify as “consistent with UIP”.
This will be defined as meeting either criteria A, B and C, or criteria A and C, or criteria B 
and C below. 
A)      Definite honeycomb lung destruction with basal and peripheral predominance.
B)      Presence of reticular abnormality AND traction bronchiectasis consistent with fibrosis 
with basal and peripheral predominance. 
C)      Atypical features are ABSENT, specifically: nodules and consolidation. Ground glass 
opacity, if present, is less extensive than reticular opacity pattern.
Appearances of a fibrosing lung disease with no definite HRCT features of a specific etiology 
will be considered “possible IPF”. Convincing HRCT appearances of a diffuse lung disease 
other than IPF will be considered “definitely not IPF”. “Possible IPF” and “definitely not 
IPF” will not be allowed for inclusion in the trial.
In the presence of a surgical lung biopsy, the histology will be reviewed based on the 
ATS/ERS/JRS/ALAT guidelines [P11-07084]. In such case, there will be a multi-disciplinary 
team approach (radiologist and pathologist) to confirm or exclude the diagnosis of IPF. An 
HRCT "possible IPF" coupled with a surgical biopsy of “definite UIP” or "probable UIP", 
upon multidisciplinary team discussion, could qualify for inclusion as “consistent with IPF”.
CREATININE CLEARANCE
10.2
Creatinine clearance calculation is done according to Cockroft and Gault [R96-0690].
Creatinine clearance = (140 - age) x (Weight in kg) x (0.85 if female) / (72 x serum creatinine 
in mg/dL)

DLCO
10.5
For predicted normal values, different sites may use different prediction formulas, based on 
the method used to measure DLCO. In any case, the method used must be in compliance with 
the ATS/ERS guideline on DLCO measurements [R06-2002], and the prediction formula 
appropriate for that method. Raw data (gas mixture, equation used for prediction of normal, 
further adjustments made if so) must be traced.
Predicted DLCO corrected for haemoglobin (Hb) expressed in g x dL-1 (R06-2002) can be 
calculated as:

Predicted DLCO corrected for Hb = Predicted DLCO x (1.7Hb/(10.22+Hb)) for males 
aged 15 years or above

Predicted DLCO corrected for Hb = Predicted DLCO x (1.7Hb/(9.38+Hb)) for 
females and children aged less than 15 years
DLCO results from Visit 1 will be corrected for haemoglobin (value obtained at Visit 1) by 
the site.
