FLOW CHART (Cont.)
1.
Visit 1 and Visit 2 may occur on the same date if the period between Visit 9 (End of Treatment) of the previous trial (1199.32 or 1199.34) and the first visit for 
1199.33 is ≤ 6 weeks. This rule does not apply to patients requiring washout of bronchodilators, as they will need to sign informed consent at Visit 1 in order to be 
asked to perform washout for PFT at Visit 2.
2.
Visit 1 should occur at least one day after the Follow-up Visit of the parent trial and Visit 2 within 12 weeks of Visit 9 (End of Treatment) of the parent trial (1199.32 
or 1199.34).
3.
The patient is required to sign informed consent prior to any study related activities.
4.
For patients performing Visit 1 and Visit 2 on the same day, eligibility assessment will be based on laboratory data from Visit 9 of the parent trial. Laboratory tests, 
physical examination and vital signs will be performed only once on that day and will be recorded under Visit 2 in the eCRF.
5.
Urine dipstick pregnancy tests will be provided by central lab and should be performed in all women of childbearing potential. If urine test is not acceptable to local 
authorities, a blood test can be done at a local laboratory.
6.
An additional visit must be performed in case of dose reduction or increase. Please refer to Section 6.2.4 for visit procedures.
7.
Only medical conditions that are occurring concomitantly at the time of screening will be recorded as baseline conditions on the 1199.33 Remote Data Capture (RDC) 
system. This also applies to ongoing AEs from the parent trial at the time of screening. See ISF for further instructions.
8.
Laboratory test only for liver function monitoring: AST, ALT and bilirubin. Blood may be collected at the investigational site, primary physician (GP or 
Pulmonologist) or external laboratory with specific study kits and sent to the central laboratory for analysis. Information, agreement and training of the primary 
physician or local laboratory will be ensured on an individual site basis.
9.
Same scheme should be repeated as often as needed: one complete visit every 16 weeks and one intermediate visit for liver function monitoring.
10. End of Treatment Visit to be performed if a reason for withdrawal is met. Please refer to Section 3.3.4.
11. A Follow-up (FU) Visit should be planned for 28 days after last drug intake (+7 days window).

FLOW CHART FOR PATIENTS WHO CONTINUE TREATMENT 
AFTER THE DATABASE LOCK FOR THE FINAL ANALYSIS1
1.
Patients who require continuation of treatment within this trial after the database lock for the final analyses will 
have reduced number of trial visits and reduced trial related procedures as described in this flow chart. The 
objective of these visits will be to dispense new study drug and collect information regarding adverse events and 
concomitant medication.
2.
Patients continuing treatment after the final analysis (patients who don’t have access to nintedanib outside the 
clinical trial) are required to sign an informed consent explaining the objective and study related procedures of the 
trial after the final analysis. This should happen prior to any study related activities of this new trial period.
3.
Same scheme should be repeated as often as needed: one visit every 16 weeks.
4.
End of Treatment Visit to be performed if a reason for withdrawal is met. Please refer to Section 3.3.4.
5.
A Follow-up (FU) Visit should be planned for 28 days after last drug intake (+7 days window).

INTRODUCTION
1.1
MEDICAL BACKGROUND
Idiopathic Pulmonary Fibrosis (IPF) is a chronic disease of unknown aetiology that is 
characterized by progressive fibrotic destruction of the lung, resulting in disabling dyspnoea
and poor gas exchange. The average life expectancy in IPF patients is 2-3 years. 
The only drug that has been registered in a number of countries for the treatment of IPF is
pirfenidone. It was launched in Japan in 2008 under the brand name Pirespa® and was 
approved for the treatment of mild-to-moderate IPF in Europe and Canada in 2011 (under the 
brand name Esbriet®). Following the successful completion of a third Phase III trial (PIPF-
016, ASCEND) pirfenidone was recently approved by the US FDA for the treatment of IPF. 
Other pharmacologic options include corticosteroids, azathioprine, cyclophosphamide, and 
N-acetyl cysteine, albeit none of these has been proven efficacious in clinical trials compared 
with placebo, and none is indicated for the treatment of IPF. Thus, despite the availability of 
pirfenidone and the possibility of lung transplantation, the medical need for efficacious and 
safe treatment of IPF remains high.
Nintedanib has been developed for the treatment of IPF and for several cancer types in two 
separate clinical development programmes. 
In IPF the clinical proof of concept for nintedanib was established in the 52-week phase II 
trial 1199.30 (P11-11216). Based on this trial, it was considered that nintedanib may confer 
clinical benefit to patients with IPF with acceptable safety.
Two phase III international, double-blind, placebo-controlled trials of identical study design 
1199.32 and 1199.34 confirmed the efficacy and safety of nintedanib 150 mg bid versus 
placebo in patients with IPF (P14-07514) (refer to Section 1.2). Based on the overall 
evidence, nintedanib was approved by the US FDA for the treatment of IPF in October 2014. 
The current study 1199.33 is a long-term extension study of the Phase III trials and such it is 
conducted to evaluate the long-term safety and tolerability of nintedanib in IPF.  
1.2
DRUG PROFILE
Nintedanib is a small molecule tyrosine kinase inhibitor of the Platelet Derived Growth 
Factor Receptor (PDGFR) α and β, Fibroblast Growth Factor Receptor (FGFR) 1- 3, and 
Vascular Endothelial Growth Factor Receptor (VEGFR). Nintedanib binds competitively to 
the 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. In addition, nintedanib inhibits Flt-3, Lck, Lyn, 
and Src kinases (U07-1248).
Nintedanib is currently in clinical development for several types of cancer. In line with the 
pre-clinical findings, the clinical development programme has provided data suggesting that

nintedanib is active against a number of advanced malignancies including lung, ovarian, 
kidney, liver, and colorectal cancer. 
Inhibition of FGFR-1 and PDGFR has been proposed as effective principle for the treatment 
of IPF (P07-00109). Furthermore, VEGFR inhibition may also have favourable effects, 
although the precise role of down-regulation of VEGF-mediated actions in IPF has not yet 
been fully elucidated (R07-0002). Oral administration of nintedanib to rats with bleomycin-
induced lung fibrosis resulted in nearly complete attenuation of fibrosis histologically not 
only when started at day 1 after bleomycin administration, but also when administered only 
from day 10 to 21. In this model, nintedanib thus may be acting directly against the fibrotic 
processes, rather than solely through inhibition of inflammation.
A soft gelatin capsule formulation of nintedanib is used in humans. After oral administration, 
nintedanib was absorbed moderately fast. Maximum plasma concentrations (Cmax) occurred 1 
to 4 hours after administration. Steady state was reached within 9 days of treatment at the 
latest. The gMean terminal half-life (t1/2) was 18 hours after intravenous administration. The 
major route of elimination of total [14C] radioactivity was via the faeces / biliary excretion, 
while the contribution of renal excretion was low (0.7% of an orally administered radioactive 
dose). An absolute bioavailability of slightly below 5% was observed by an intra-individual 
comparison of dose normalized AUC of 100 mg nintedanib administered orally and 6 mg 
nintedanib administered intravenously. The total percentage absorbed was estimated to be at 
least 23% compared to an absolute bioavailability of the parent alone of about 5%, thereby 
confirming the large amount of metabolite formed during intestinal and/or hepatic first pass 
metabolism. 
The by far most frequent metabolites were BIBF 1202 formed by ester cleavage and the 
subsequently glucuronidation formed BIBF 1202-glucuronide. The glucuronidation of 
BIBF 1202 was mainly through UGT1A1 (liver and intestine) and UGT1A7, UGT1A8 and 
UGT1A10 (intestine). Drug-drug interactions based on cytochrome P450 dependent 
pathways are not expected for nintedanib.
In vitro transporter profiling of BIBF 1120 and BIBF 1202 showed that BIBF 1120 - but not 
BIBF 1202 - is a P-gp substrate. The effect of xenobiotics interacting with P-gp is currently 
not known.
In the IPF phase II proof-of-concept trial 1199.30, 432 patients with consistent IPF were 
randomized, with baseline characteristics comparable across groups. The results of the 
primary endpoint analyses, annual rate of FVC decline, were: 0.19 L (placebo); 0.17 L (50 
mg qd); 0.21 L (50 mg bid); 0.16 L (100 mg bid); and 0.06 L (150 mg bid: -68% reduction in 
rate of decline vs. placebo, p=0.0136; closed-testing multiplicity corrected: p=0.0639). At 
end of study, FVC% pred was better preserved in the 100 mg bid (p=0.0314) and 150 mg bid 
(p=0.0002) groups when compared to placebo. FVC signal robustness was supported by 
results of body plethysmography and oxygen saturation. Compared to placebo, fewer patients 
had acute exacerbations in the 150 mg bid group (p=0.0150), and there were a greater number 
of SGRQ 4-point scale responders in the 100 mg bid (p=0.0069) and 150 mg bid (p=0.0341) 
groups.  No effect was observed on DLCO and 6-MWT. The number of deaths was not

significantly different between groups. Discontinuations (26.2%; 22.4% due to AE) were 
more frequent with 150 mg bid (37.6%; 31.8%), but less with 100 mg bid (16.3%; 15.1%), 
compared to placebo (28.2%; 24.7%).
The adverse events most frequently leading to discontinuation were diarrhoea, nausea, and 
vomiting (in the group receiving 150 mg twice a day as compared with those receiving 
placebo, the respective rates were 11.8% vs. 0%, 4.7% vs. 0%, and 2.4% vs. 1.2%). Among 
the 85 patients in the group receiving 150 mg of the study drug twice a day, 4 (4.7%) had 
serious gastrointestinal events and 5 (5.9%) had severe gastrointestinal events, especially 
diarrhoea, as compared with no patients in the placebo group.
Clinically significant elevations in liver enzymes levels (at least three times the upper limit of 
the normal range for ALT or AST at any time after baseline) were observed in 6 patients in 
the group receiving 150 mg of nintedanib twice a day (7.1%), 1 in the group receiving 100 
mg twice a day and none in the placebo group. All aminotransferase levels normalized or 
decreased from elevated levels with continued treatment (in 3 patients receiving 150 mg 
twice a day and 1 patient receiving 100 mg twice a day), with a dose reduction (from 150 mg 
twice a day to 100 mg twice a day in 1 patient), or with withdrawal of the drug (in 2 patients 
receiving 150 mg twice a day). 
For patients of the Phase II study participation in the open label rollover trial 1199.35 was 
offered. This study is currently ongoing. 
Overall, it was considered that nintedanib may confer clinical benefit to patients with IPF 
with an acceptable safety profile. The benefit/risk assessment of the Phase II trial results 
justified initiation of 2 large Phase III trials. Trials 1199.32 (U13-2381-01) and 1199.34 
(U13-2382-01), which are the parent trials of the current 1199.33 trial, evaluated the safety 
and efficacy of the 150 mg bid dose versus placebo when given over 52 weeks. 
In total 515 patients were randomised in study 1199.32 and 551 patients in study 1199.34. 
The primary endpoint of the annual rate of decline in FVC was met in both studies. In study 
1199.32 the adjusted annual rate of decline in FVC was -239.91 mL/year in the placebo 
group and -114.65 mL/year in the nintedanib group. The difference between treatment groups 
was 125.26 mL/year (95% CI: 77.68, 172.84) and was statistically significant (p<0.0001). In 
study 1199.34 the adjusted annual rate of decline in FVC was -207.32 mL/year in the placebo 
group and -113.59 mL/year in the nintedanib group. The difference between the treatment 
groups was 93.73 mL/year (95% CI: 44.78, 142.68) and was statistically significant 
(p=0.0002). 
Change from baseline in SGRQ total score at 52 weeks was a key secondary endpoint in the 
studies. In study 1199.32 there was a small difference between the treatment groups in favour 
of nintedanib: -0.05 (95% CI: -2.40, 2.50), which was not statistically significant (p=0.966). 
In study 1199.34 the difference between the treatment groups was -2.69 (95% CI:-4.95, -
0.43) in favour of nintedanib and was statistically significant (p=0.0197).

Time to first acute IPF exacerbation over 52 weeks was a key secondary endpoint in the 
studies. In study 1199.32 there was no difference between the treatment groups and the 
hazard ratio (HR) was 1.15 (95% CI: 0.54, 2.42; p=0.673). In study 1199.34 the risk of  
having a first acute IPF exacerbation was significantly lower in the nintedanib group than in 
the placebo group, with a HR of 0.38 (95% CI: 0.19, 0.77; p=0.005).
In both studies, survival endpoints showed a consistent numerical difference in favour of 
nintedanib. The HR for time to death over 52 weeks in a pre-specified pooled analysis of both 
studies was 0.70 (95% CI 0.43, 1.12; p = 0.1399).
As expected, the most frequent AEs were gastrointestinal disorders. Diarrhoea was reported 
in 61.5% of the patients in the nintedanib group in study 1199.32 and in 63.2% of the patients 
in study 1199.34 compared to 18.6% and 18.3% in the placebo group, respectively. Liver 
enzyme elevations were more frequent in the nintedanib group than in the placebo group in 
both studies: aspartate aminotransferase [AST] and/or alanine aminotransferase [ALT] 
≥3xULN was observed in 4.9% of the patients in the nintedanib group versus 0.5% of the 
patients in the placebo group in study 1199.32 and in 5.2% of the patients in the nintedanib 
group versus 0.9% of the patients in the placebo group in study 1199.34. There was no Hy’s 
law case in the nintedanib group.
Please refer to the current version of the Investigator’s Brochure (U07-1248) for complete 
and updated information on nintedanib in IPF.

RATIONALE, OBJECTIVES, AND BENEFIT - RISK 
ASSESSMENT
2.1
RATIONALE FOR PERFORMING THE TRIAL
The aim of this extension trial is to provide nintedanib treatment for all patients who have 
completed one year treatment and the follow up period in the double-blind phase III placebo 
controlled parent trials (1199.32 and 1199.34), who may have experienced benefit from the 
study medication and wish to receive treatment.
Moreover it is designed to determine the tolerability and safety of nintedanib and to follow up 
on survival in IPF patients treated for a long period.
Throughout this protocol, each time “parent trial” is quoted it refers to the 1199.32 and 
1199.34 trials (EudraCT no. 2010-024251-87 and no. 2010-024252-29).
2.2
TRIAL OBJECTIVES
The primary objective is to assess long term safety of treatment with oral nintedanib in 
patients with Idiopathic Pulmonary Fibrosis (IPF).
Please refer to Section 5 for a detailed description of the trial endpoints.
2.3
BENEFIT - RISK ASSESSMENT
Nintedanib has shown robust, reproducible, statistically significant, and clinically meaningful 
effects on the decline in lung function as measured by FVC. In two large, international, 
placebo-controlled phase III trials of identical design, nintedanib 150 mg bid statistically and 
clinically significantly reduced the annual rate of decline in FVC over 52 weeks compared 
with placebo indicating a relative difference of approximately 50% between nintedanib and 
placebo. This effect of nintedanib is considered consistent with slowing disease progression 
as measured by FVC.
The risks of treatment with nintedanib are primarily related to the gastrointestinal tract 
(nausea, vomiting, diarrhoea, abdominal pain) and to increases in liver enzymes (AST, ALT, 
ALKP, gamma-GT) and bilirubin. Also weight decrease and decreased appetite have 
frequently been reported in studies with nintedanib. Moreover, based on experience with 
other tyrosine kinase inhibitors, impairment of immune and of kidney function, intestinal 
perforations, increases in blood pressure as well as potential bleeding and thrombotic events
should be carefully monitored and evaluated in clinical trials. In patients who develop severe
symptoms of gastrointestinal toxicity not amenable to symptomatic treatment with standard
measures, severe liver enzyme elevations, severe drug-related infections, or uncontrolled
hypertension, treatment with nintedanib must be discontinued and appropriate therapeutic
measures taken (refer to Section 4.2.1.1). Liver enzymes must be followed closely during 
treatment with nintedanib.

The dose of nintedanib must be reduced to 100mg bid, or nintedanib must be discontinued in 
the event of hepatic toxicity and further treatment withheld until recovery of the abnormal 
laboratory parameters (refer to Section 4.2.1.2).
Patients with IPF may benefit from lesser decline in lung function and hence slower disease
progression as a result of treatment with nintedanib. In addition, nintedanib may reduce the 
risk of acute IPF exacerbations and worsening of patient’s quality of life. Finally, nintedanib
may ultimately be found to reduce mortality. Overall, the benefit/risk profile of nintedanib, as 
established during the phase II and III trials is interpreted as favourable for the treatment of 
IPF.
Although rare, a potential for drug-induced liver injury is under constant surveillance by 
sponsors and regulators. Therefore, this study requires timely detection, evaluation, and 
follow-up of laboratory alterations of selected liver laboratory parameters to ensure patients’ 
safety.
Patients who are offered to enter this open label extension trial must have participated in a 
phase III parent trial (1199.32 or 1199.34) for one year. All patients will be treated with 
active drug. Patients who have not tolerated the blinded study drug or discontinued for any 
reason are not eligible for the extension trial. Patients who were randomized to placebo in the 
parent trial will be receiving the active drug for the first time. Similar safety monitoring
procedures as in the phase III trials will be applied.
The routine safety monitoring established in the parent study is considered appropriate for the 
long term follow-up of the patients. It consists of regular visits to the investigational site, 
blood analyses and specific monitoring procedures to follow-up potential hepatic enzyme 
elevation. In case it is considered adequate by the investigator, the dose of nintedanib may be 
reduced to 100 mg bid or dosing may be interrupted.

DESCRIPTION OF DESIGN AND TRIAL POPULATION
3.1
OVERALL TRIAL DESIGN AND PLAN
This is a multi-centre, multi-national, prospective, open label extension clinical trial. It is 
planned to include approximately 750 patients with IPF who have completed 52 weeks of 
treatment and the follow up period of the phase III parent trials. Only patients enrolled in the 
parent trials (1199.32 and 1199.34) will be eligible.
After signing Informed Consent and if all eligibility criteria are met, patients will initiate 
treatment with nintedanib (Visit 2). Please refer to Section 4.1.2 for the method of assigning 
patients to treatment groups.
Overall, the trial is estimated to last a total of approximately 6 ½ years. Treatment will be 
stopped if a reason for withdrawal is met (refer to Section 3.3.4). 
Patients’ participation starts once they have signed the Informed Consent form and it is 
concluded when they have undergone the Follow-up Visit (unless the patient is lost to follow 
up or informed consent is withdrawn). Adverse events are collected during all the trial period 
and are considered under treatment until 28 days after drug discontinuation.
3.1.1
Administrative structure of the trial
The trial is sponsored by Boehringer Ingelheim (BI).
BI 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, ordering the materials as needed for the trial, ensuring 
appropriate training and information of Clinical Monitors Local (CML), Clinical Research 
Associates (CRAs), and investigators of participating countries.
Data Management and Statistical evaluation will be performed 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 will be given in the Clinical Trial 
Master File (CTMF) document.
The organisation of the trial in the participating countries will be done by the respective local 
BI organisation (Operating Unit (OPU)) or by a Contract Research Organisation (CRO) with 
which the responsibilities and tasks will have been agreed and a written contract filed before 
initiation of the clinical trial. In each OPU participating in this study, a CML was appointed 
responsible for coordinating the activities required in order to manage the trial in accordance 
with applicable regulations and internal SOPs in the countries covered by the respective BI 
OPU.

signature on the final protocol signature page and amendments and will provide 
 signature 
on the (draft) Clinical Trial Report (CTR) indicating that, to the best of Co-ordinator’s 
knowledge, the final CTR accurately describes the conduct and results of the Trial.
Trial sites consist of specialised referral centres experienced in the management of IPF. 
Documents on participating (Principal) investigators and other important participants, 
especially their curricula vitae, will be filed in the CTMF.
Details of the trial supplies including responsible institutions are given in Section 4 of this 
protocol.
Central laboratory facilities will handle all laboratory analyses of the trial. In addition liver 
enzymes intermediate measurements may be performed in a local laboratory or at a local 
doctor’s office using specific laboratory kits supplied for the study that will be analysed 
centrally.
To assure the standardisation of PFTs, the lung function equipment for spirometry will be 
provided by the sponsor (refer to Section 5.2). 
The ISF will be maintained at the sites as required by local regulation and BI SOP. A copy of 
the ISF documents will be kept as an electronic CTMF document according to BI SOPs.
3.2
DISCUSSION OF TRIAL DESIGN, INCLUDING THE CHOICE OF 
CONTROL GROUP
The trial will be conducted as a prospective, open-label design with the objective to collect 
long term safety data on nintedanib in patients with IPF. The observation period will extend 
until either every patient is discontinued or a reason for stopping the trial is met (refer to 
Section 3.3.4). Patients who have completed one year treatment plus follow-up period in a 
parent trial are eligible for participation.
The purpose of this trial is to offer the option to all patients who completed the randomized 
phase III trial 1199.32 or 1199.34 to receive nintedanib treatment if they perceive an 
individual benefit. The decision to continue treatment will be made by the patient following a 
discussion with the investigator. The aim of the study is to allow treatment continuation to 
individual patients; therefore, randomization, blinding and use of placebo would not be 
appropriate. 
To obtain information on the long term safety and tolerability of nintedanib, adverse events
and acute IPF exacerbations will be reported, and clinical laboratory tests, electrocardiograms
and lung function tests will be performed. FVC derived endpoints will be assessed and data
on discontinuations and death will be recorded.

3.3
SELECTION OF TRIAL POPULATION
It is anticipated that approximately 750 patients will complete 52 weeks of treatment with 
nintedanib or placebo and the follow up period in the phase III trials 1199.32 and 1199.34
(assuming a similar drop-out rate as in the phase II). These patients will be allowed to 
participate in this extension trial. Patients previously on active treatment will continue; 
patients who received placebo in the parent trial will initiate treatment with nintedanib for the 
first time at Visit 2.
A log of all patients included in 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 (i.e. open label nintedanib) or not.
3.3.1
Main diagnosis for study entry 
Patients with IPF are eligible for inclusion if they fulfil all the inclusion criteria (Section 
3.3.2) and do not present any of the exclusion criteria (Section 3.3.3).
In general patients who have completed the parent trial are eligible. However treatment 
interruption between the parent trial and the extension open label study should not be > 12 
weeks. Patients who had experienced adverse events in the parent trial but were allowed to 
continue receiving blinded study medication either at 150 mg bid dose or at the reduced dose 
level 100 mg bid, will be offered participation in the extension trial. 
3.3.2
Inclusion criteria
1. Signed Informed Consent consistent with ICH-GCP and local laws prior to trial 
participation.
2. Patients from trials 1199.32 or 1199.34 who completed the 52 weeks treatment period

sperm in the ejaculate).
3.3.4
Removal of patients from therapy or assessments
3.3.4.1
Removal of individual patients
The treatment with nintedanib has to be permanently discontinued in the following 
circumstances:

Liver function impairment (refer to Section 10.1):

ALT or AST ≥8 fold ULN.

ALT or AST ≥3 fold ULN for more than 2 weeks despite dose 
reduction.

ALT or AST ≥3 fold ULN and total bilirubin > 1.5 fold ULN.

ALT or AST ≥ 3 fold ULN and INR > 1.5.

ALT or AST ≥3 fold ULN with the appearance of fatigue, nausea, 
vomiting, right upper abdominal quadrant pain or tenderness, fever, 
rash, and/or eosinophilia (> 5%).

Diarrhoea: reoccurrence of diarrhoea (> 4 stools/day) for 8 or more consecutive 
days despite dose reduction and supportive care as described in Section 4.2.1.1.

Pregnancy (refer to Section 5.3.7).

Planned usage of a specific investigational drug (refer to Section 4.2.2.1).

Treatment interruption. Treatment interruption is acceptable in certain cases and 
for a defined period which are described in Section 4.2.1. 
Similar to the parent study, in the following cases withdrawal of study drug is highly 
recommended. Only in special circumstances, the investigator, upon thorough assessment of 
all available clinical data, and taking into consideration the potential risks associated with 
administration of nintedanib, may decide not to withdraw the patient, even though one or 
more of the below mentioned criteria are fulfilled. However, in such a case, continuation of 
study treatment should be discussed with the patient, and the decision documented in the 
source data.

TREATMENTS
4.1
TREATMENTS TO BE ADMINISTERED
Nintedanib will be supplied by Boehringer Ingelheim Pharma GmbH & Co. KG.
4.1.1
Identity of BI investigational product and comparator product
All patients will be treated with nintedanib in this trial; there is no active comparator or 
placebo.
Substance:
nintedanib
Pharmaceutical form:
Soft gelatin capsule
Source:
BI Pharma GmbH Co. KG
Unit strengths:
150 mg , 100 mg
Posology:
Twice daily (bid)
Route of administration:
Oral (swallowed)
4.1.2
Method of assigning patients to treatment groups
In the parent blind phase III trials (1199.32 and 1199.34) patients are assigned either active 
drug (nintedanib 150 mg bid) or placebo. In case patients experience adverse events related to 
drug tolerability, a dose reduction to 100 mg bid is allowed (both in active or placebo group).
At the end of treatment (Visit 9) in the parent trials, patients will be taking either 150 mg bid 
blinded study medication (active drug or placebo) or 100 mg bid blinded study medication 
(active drug or placebo) if their dose was permanently reduced during the trial.
Patients taking 150 mg bid blinded study medication (active drug or placebo) in the parent 
trial will be treated with nintedanib 150 mg bid in the current extension trial.
Patients who had the dose reduced to 100 mg bid (active drug or placebo) in the parent trial 
will be allowed to be treated with nintedanib 100 mg bid or 150 mg bid. This will ensure that 
patients who were on reduced dose placebo in the parent trial will have a chance to get the 
full dose in the extension trial. 
The daily dose of nintedanib will be decided at Visit 2 based on discussion between the 
patient and the investigator.

An Interactive Voice Response System (IVRS) / !"#$%&'#()$ 
*$+ ,$-./"-$ 
01-#$2 3!*,04
will be used to assign medication numbers to eligible patients. Distribution of nintedanib to 
sites will be triggered by IVRS/IWRS.
Details on the IVRS/IWRS system are provided in the ISF.
After conclusion and unblinding of the parent trials, patients who received 100 mg bid (active 
drug or placebo) will also be allowed to increase their nintedanib dose to 150 mg bid, if this 
was not already performed at the beginning of the extension trial and if it is medically 
justified. In this situation, dose increase will need to be assigned through IVRS/IWRS during 
an additional visit (refer to Section 6.2.4).
4.1.3
Selection of doses in the trial
Based on the phase II safety and dose-finding trial 1199.30, a dose of 150 mg bid was 
selected for confirmatory phase III trials (1199.32/.34) (U07-1248). With 150 mg bid, the 
limit of tolerability in IPF patients is considered to be reached. Lower doses may not ensure 
full efficacy benefit. However, in case of lack of tolerability, the dose may be reduced
temporarily or permanently to 100 mg bid. 
4.1.4
Drug assignment and administration of doses for each patient
At Visit 2 patients who meet all eligibility criteria will be assigned trial drug: nintedanib
either 150 mg or 100 mg bid (refer to Section 4.1.2). 
Boxes covering 4 weeks + 1 week reserve treatment will be dispensed to the patient:
-
1 box at day 1 (Visit 2);
-
2 boxes at Visit 4;
-
3 boxes at Visits 6, 7 and 8;
-
4 boxes at Visit 9 and following visits.
Please refer to the Flow Chart for dispensing schedule. The investigational product should 
only be dispensed to participating patients according to the protocol by authorised personnel 
as documented in the form “Trial Staff List”. 
Study drug will be administered orally on a twice daily basis (bid). The patients should 
swallow the study medication unchewed together with a glass of water (~250 mL), and 
should observe a dose interval of 12 hours. Study drug should be taken at the same time every 
day (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 drug after
food consumption.

4.2
CONCOMITANT THERAPY, RESTRICTIONS, AND RESCUE 
TREATMENT
4.2.1
Rescue medication, emergency procedures, and additional treatment
An antidote against nintedanib is not available. Potential side effects of nintedanib have to be 
treated symptomatically.
Dose reduction (150 mg bid to 100 mg bid) or treatment interruption should be considered to 
manage adverse events. No further dose reduction is possible for patients on the 100 mg bid 
regimen. In case of adverse events observed at this dose, treatment interruption should be 
considered.
4.2.1.1
Management of diarrhoea
The guidelines for managing diarrhoea are the same as in the parent protocols.
4-6 extra stools or i.v. fluid intake < 24 hours with no effect on daily living activities 
Patients should be treated according to local standard (e.g. loperamide or equivalent).
If the severity of diarrhoea persists for 8 or more consecutive days despite optimal care, 
nintedanib treatment should be discontinued or reduced until return to less than 4 extra stools 
per day. Drug interruption is limited however to a maximum of 4 weeks and patients may 
restart treatment with nintedanib at a reduced dose (during a dose modification visit, refer to 
Section 6.2.4). 
Dose re-escalation is allowed at any time after the beginning of the reduced dose if medically 
justified.
In case of re-occurrence of diarrhoea for 8 or more consecutive days despite dose reduction 
and after optimal or prophylactic therapy, patients have to permanently stop nintedanib and 
perform an End of Treatment Visit as soon as possible and a Follow-up Visit 28 days after 
last drug intake (refer to the Flow Chart for visit procedures).
> 6 extra stools or incontinence or i.v. fluid intake ≥ 24 hours or hospitalisation or decrease in 
daily living activities
Nintedanib has to be interrupted until return to less than 4 extra stools per day and patients 
should be treated with optimal supportive care (e.g. loperamide or equivalent). Thereafter, 
patients may restart treatment with nintedanib at a reduced dose. 
In case of re-occurrence of diarrhoea for 8 or more consecutive days despite dose reduction 
and after optimal or prophylactic therapy, patients have to permanently stop nintedanib and 
perform an End of Treatment Visit as soon as possible and a Follow-up Visit 28 days after 
last drug intake (refer to the Flow Chart for visit procedures).


Patients showing these lab abnormalities need to be followed up according to
Section 10.1.1 of this clinical trial protocol and the “DILI checklist” provided in 
ISF.
Signs of severe liver damage are defined as:
Increase of liver transaminases (ALT or AST ≥ 3 fold ULN) and:

appearance of fatigue, nausea, vomiting, right upper abdominal quadrant pain or 
tenderness, fever, rash, and/or eosinophilia (> 5%); or

Total bilirubin > 1.5 fold ULN; or

INR > 1.5;
Please refer to Section 10.1 for more detailed instructions.
Immediately refer to Section 5.3.6.1 in case AST and/or ALT ≥ 3 fold ULN is combined with 
total bilirubin ≥ 2 fold ULN.
Initial assessment of liver enzyme elevation should be performed at the investigational site. 
Blood samples for additional monitoring may be collected at the investigational site, primary 
physician (GP or Pulmonologist) or external laboratory with specific study kits and sent to 
the central laboratory for analysis.
For patients continuing treatment with nintedanib within this trial after the database lock for 
the final analysis, the liver function monitoring is to be done locally in case of liver enzyme 
elevations. 
4.2.1.3
Management of acute exacerbations
In case of acute exacerbation (refer to Section 5.2), all treatment options considered adequate 
by the investigator / caregiver are allowed. The patient may interrupt study treatment for up 
to 8 weeks if this is considered necessary (e.g., if short-term full anticoagulation is 
performed).
4.2.1.4
Management of other adverse events
Patients who develop an uncontrolled hypertension despite appropriate antihypertensive 
therapy should permanently discontinue study medication.
For AEs that are assessed drug related, a dose reduction or an interruption (of maximum 4 
weeks) can be considered. Re-escalation is allowed at any time after start of dose reduction if 
medically justified.

For non related AEs, drug interruption may occur for no longer than 12 weeks. Nintedanib
should be re-started at the same dose as it was being taken before interruption.
Summary of allowed interruption periods: 

Acute IPF exacerbations: 8 weeks maximum interruption;

Related AEs: 4 weeks maximum interruption, then dose reduction is recommended, 
then re-escalation to full dose (150 mg bid) is allowed at any time;

Unrelated AEs: 12 weeks maximum interruption.
4.2.2
Restrictions
4.2.2.1
Restrictions regarding concomitant treatment

Investigational therapy is not allowed during the entire study period and must not 
have been introduced in the interval between parent trial and enrolment into this 
extension trial. 

Nintedanib is an anti-fibrotic kinase inhibitor which has been shown to have anti-
angiogenic properties. Inhibition of angiogenesis may increase susceptibility to 
bleeding. Therefore, concomitant anticoagulation, fibrinolysis or high-dose 
antiplatelet therapy is contra-indicated (refer to Section 3.3.3 [4 weeks washout]). 
Patients who require fibrinolysis, full-dose therapeutic anticoagulation (e.g. vitamin K 
antagonists, dabigatran, heparin, hirudin), or high dose antiplatelet therapy are to be 
withdrawn. Prophylactic low dose heparin or heparin flush as needed for maintenance 
of an indwelling intravenous device (e.g. enoxaparin 4000 IU s.c. per day), as well as 
prophylactic use of antiplatelet therapy (e.g. acetyl salicylic acid up to 325 mg/d, or 
clopidogrel at 75 mg/d, or equivalent doses of other antiplatelet therapy) should be 
allowed.

The concomitant administration of nintedanib with any drugs which are likely to 
increase gastrointestinal events such as diarrhoea, nausea, vomiting, is discouraged.

Washout of bronchodilators must be observed before spirometry: 24 hours for long 
acting and 8 hours for short acting bronchodilators, if applicable.
4.2.2.2
Restrictions on diet and life style
No restrictions on diet or life style.

4.3
TREATMENT COMPLIANCE
Study medication will be dispensed to the patient at the study site by responsible site 
personnel. Details regarding dispensing of the study medication to each participating patient, 
including patient identification, the amount of study drug dispensed, the date the drug was 
dispensed, and the number of capsules returned to the site will be recorded in the drug 
accountability form. 
Patients will be instructed to bring all study medication to the clinic at each visit (except 
Visits 3 and 5). The investigator will be responsible for the assessment of patient compliance
and will be encouraged to counsel patients on the importance of taking study medication as 
directed at each visit.
Study medication will be counted by the investigator (or designated site personnel) and 
compliance will be calculated in a worksheet, which must be kept as a source document.
Compliance will be calculated according to the formula: Compliance (%) = Number of 
capsules actually taken since last count × 100 / Number of capsules which should have been 
taken in the same period. Compliance to nintedanib should be between 80% and 120%. 
Patients should not be discontinued for lack of compliance without prior discussion with the 
clinical monitor.

VARIABLES AND THEIR ASSESSMENT
5.1
TRIAL ENDPOINTS 
5.1.1
Primary Endpoint 
The primary endpoint is the incidence (number and % of patients) of overall adverse events 
over the course of the study, including incidence (number and % of patients) of serious 
adverse events; adverse events leading to discontinuation and fatal adverse events.
5.1.2
Secondary Endpoints
Not applicable.
5.2
ASSESSMENT OF EFFICACY 
Measurements of FVC
Unique spirometry devices (identical to the ones used in the parent studies) will be supplied 
to all participating sites at trial initiation and spirometry performance will be centrally 
reviewed. During the course of the trial and specifically at each interim analysis, the sponsor 
will re-evaluate the use of central spirometry. If applicable, i.e. central spirometry will be no 
longer used, measurements of FVC will be performed using calibrated electronic spirometers 
at the investigational site or at a referral site.
Spirometers and usage of spirometers must meet ATS/ERS criteria (P05-12782), including 
daily calibration of the spirometer, and regular calibration of the calibration pump. 
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 
captured by spirometers provided by the sponsor will be electronically transmitted and 
confirmed by central reading. 
For each patient, pulmonary function testing will always start at approximately the same time 
of the day (with 60 minutes maximum difference, time will be recorded). On days of clinic 
visits, 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).
Definition of Acute IPF Exacerbations
Otherwise unexplained clinical features within one month, including all of the following:

Unexplained worsening or development of dyspnoea within 30 days;

New diffuse pulmonary infiltrates on chest X-ray, and/or new HRCT parenchymal 
abnormalities with no pneumothorax or pleural effusion (new ground-glass opacities) 
since last visit;

Exclusion of infection as per routine clinical practice and microbiological studies;

Exclusion of alternative causes as per routine clinical practice, including:

left heart failure, 

pulmonary embolism,

identifiable cause of acute lung injury.
Acute IPF exacerbations will be collected as adverse events.
5.3
ASSESSMENT OF SAFETY
5.3.1
Physical examination
Physical examination includes assessment of heart, lung, abdomen and measurement of 
weight. Abnormal findings in the parent trial which were recorded as an adverse event and 
are still ongoing at the time of screening, as well as any new abnormal finding at the time of 
screening, will be recorded as baseline conditions on the appropriate eCRF page. New 
abnormal 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: red blood cell count, haemoglobin, haematocrit, mean corpuscular 
volume, white blood cell count including differential, platelet count.

Chemistry: creatinine, AST, ALT, total protein, alkaline phosphatase, total 
bilirubin.

Coagulation: International normalized ratio (INR) and partial thromboplastin time 
(PTT).
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. 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. 
Additionally, all patients will have intermediate liver function monitoring visits (AST, ALT 
and bilirubin) when the interval between 2 regular visits exceeds 8 weeks. At these visits 
blood may be collected at the investigational site, primary physician (GP or Pulmonologist) 
or external laboratory. However analysis will still be performed by the central laboratory.
In case of liver enzymes elevation, close monitoring must be ensured by the investigator 
(please refer to Section 4.2.1.2). 
For patients continuing treatment with nintedanib within this trial after the database lock for 
the final analysis, laboratory tests will no longer be part of the trial related procedures. 
However investigators are encouraged to monitor liver function locally according to the 
recommendations provided in the Investigators Brochure and to manage liver enzyme 
elevations according to the recommendations provided in section 4.2.1.2 Management of 
liver enzyme elevations.

5.3.4
Electrocardiogram
Regular ECGs are to be conducted during the first year of the trial. Rate, rhythm and 
repolarisation changes have to be looked at, compared to previous one, and assessed for 
clinical relevance. Clinically relevant findings at baseline of this trial will be recorded as 
baseline conditions, new abnormal findings thereafter will be recorded as adverse events.

Assessment of adverse events
5.3.6.1
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.
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.
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. 
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, ECG, physical examination, and laboratory test results
Changes in vital signs, ECG, 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 significant events
Similar to the parent trials, the following are considered as Protocol-specified significant 
events:

Hepatic injury defined by an elevation of AST and/or ALT ≥ 3 fold ULN combined 
with an elevation of bilirubin ≥ 2 fold ULN measured in the same blood draw sample.
Patients showing these lab abnormalities need to be followed up according to Section 
10.1.1 of this clinical trial protocol and the “DILI checklist” provided in ISF.

Adverse events relating to gastrointestinal perforation.
Protocol-specified significant events are to be reported in an expedited manner similar to 
Serious Adverse Events, even if they do not meet any of the seriousness criteria – for details 
please see Section 5.3.7.
Expected Adverse Events
Expected (listed) AEs are described in Section 7.9 of the Investigator’s Brochure (U07-1248).

5.3.7 
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 observational period of 28 days) 
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 the onset date, end date, intensity, 
treatment required, outcome, seriousness, and action taken with the investigational drug. The 
investigator will determine the relationship of the investigational drug to all AEs as defined in 
Section 5.3.6.1. 
The investigator also has the responsibility to report AEs occurring in a certain period (28 
days) after a patient completes the study drug administration. After this defined period all 
SAEs related to the study drug and/or study design have to be reported by the investigator.
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 occurring at the same time as an SAE and/or which are medically 
related to the SAE(s), and protocol-specified significant events. 
Boehringer Ingelheim has set up a list of AEs which are defined to be always serious. 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.
The list of these adverse events can be found in the ISF.
Additional information for Japan: This information must be also reported immediately to the 
head of the trial site. 
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.
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 significant events becomes available. 
Pregnancy
As mentioned above, due to the reprotoxic potential of nintedanib, a patient must not become 
pregnant while treated with nintedanib and until 3 months after end of treatment.

However, generally, 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 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).

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 trial will run until all patients have discontinued treatment or a stopping criterion is met 
according to Section 3.3.4.
6.2
DETAILS OF TRIAL PROCEDURES AT SELECTED VISITS
6.2.1
Screening
The study will be explained to all patients who complete the parent trials and are willing to 
continue treatment with nintedanib. No study related procedure should be performed until the 
patient has signed the Informed Consent.
Patients will complete a 52 weeks treatment period with nintedanib (or placebo) at Visit 9 in 
the parent trial (1199.32 or 1199.34) and a follow-up period of at least 28 days without drug
(Follow-up Visit).
After concluding all visits from the parent trial and in order to assess eligibility for the 
extension trial (1199.33), patients are required to perform a screening visit (Visit 1) which 
includes laboratory tests. 
If the period between Visit 9 (End of Treatment) of the parent trial and the first visit of 
1199.33 is ≤ 6 weeks, Visit 1 and Visit 2 may occur on the same date. In this case, eligibility 
assessment will be based on laboratory data from Visit 9 of the parent trial.
Please refer to the Flow Chart for complete procedures at Visit 1.
Patients who have a laboratory test value that is outside the range specified by the exclusion 
criteria may have the test repeated once to determine eligibility; however, the result must be 
available prior to Visit 2.
Details of any patient who has given informed consent for the trial but is found to be 
ineligible must be entered in the Enrolment log and documented in the eCRF.

6.2.2
Treatment period
If the patient has been determined eligible by the investigator to enter the trial (refer to 
Section 3.3), the investigator will assign a medication number to the patient through 
IVRS/IWRS at Visit 2 (refer to Section 4.1.2). First dose of nintedanib will be administered 
at Visit 2 in the clinic (day 1).
Additional clinic visits will be scheduled after 2, 4, 6, 12, 24, 36 and 48 weeks of treatment 
(Visits 3-9).  Liver function monitoring visits will be performed at 18, 30 and 42 weeks of 
treatment (Visits 6a, 7a and 8a). After the first year of treatment, complete clinic visits will be 
scheduled every 16 weeks with intermediate liver function monitoring visits.
For detailed description of the trial procedures at each visit and dispensing schedule, please 
refer to the Flow Chart.
End of Treatment (EOT)
If a reason for drug discontinuation is met (refer to Section 3.3.4) an EOT Visit should be 
scheduled as soon as possible after last drug intake. Reason for discontinuation must be 
documented in the eCRF.
For detailed description of the trial procedures at the EOT visit, please refer to the Flow 
Chart.
6.2.3
End of trial and follow-up period
A Follow-up (FU) Visit should be planned for 28 days after last drug intake.
For detailed description of the trial procedures at the FU Visit, please refer to the Flow Chart. 
If the reason for removal of a patient from the treatment is an adverse event or an abnormal 
laboratory test result, the patient must be followed until complete resolution or stabilization 
of the event for at least 28 days after onset of the event or until follow-up is considered
adequate by the investigator and the clinical monitor.
A patient will be considered lost to follow-up if the investigator is not able to contact him/her 
despite multiple attempts. Every effort must be made; at least 2 telephone contacts plus 1 
mailing should be documented. The site must notify the clinical monitor prior to designating 
a patient as lost to follow-up. 
6.2.4
Dose modification visit
Every time a dose should be reduced or increased (refer to Section 4.1.4 and Section 4.2.1) 
patients will need to come to the site for a dose modification visit where the following will be 
performed:

After the database lock for the final analysis (refer to section 7.3) and once consent has 
been provided, the remaining patients in the trial (patients without access to nintedanib 
outside the clinical trial) will be offered continuation of treatment within the trial. This 
period will consist of study visits every 16 weeks (±2 weeks) where the following 
procedures will be conducted:

Assessment of adverse events and concomitant therapy since last visit;

Dispensing of trial drug.
Patients will continue to receive treatment until they meet a reason for discontinuation 
(refer to section 3.3.4) or until access to nintedanib is obtained outside the clinical trial. 
Dose reductions, interruptions and re-escalations are possible at any time during the 
scheduled study visits or between visits to manage adverse events.
End of treatment and follow up visits have to be performed to conclude the treatment 
period and trial participation.
Study procedures per visit are described in the Flow Chart for patients who continue 
treatment after the database lock for the final analysis. Investigators are encouraged to 
monitor liver function locally according to the recommendations provided in the 
Investigators Brochure.

STATISTICAL METHODS AND DETERMINATION OF 
SAMPLE SIZE
7.1
STATISTICAL DESIGN - MODEL
This is a multicenter, multi-national, open-label clinical trial to investigate the long term 
safety of nintedanib in patients with IPF previously treated in a double-blind phase III
placebo controlled trial (1199.32 or 1199.34).
This statistical paragraph deals with the analyses to be performed on the extension trial only. 
Although data of parent trial will not be described in the scope of these analyses, they will be 
taken into account for adverse events analyses, as described in Section 7.3.4.
As the main objective of this extension trial is to study long-term safety, only descriptive 
statistics will be used. 
7.2
NULL AND ALTERNATIVE HYPOTHESES
All analyses in this trial are descriptive and exploratory in nature. No formal statistical 
inferences are foreseen.
7.3
PLANNED ANALYSES
The treated set (TS) will consist of all patients who received at least one dose of open-label 
study medication.
The definition of important protocol violations (IPV) will be specified in the trial statistical 
analysis plan (TSAP). These IPV definitions will include consideration of important 
violations of entry criteria, treatment non-compliance, prohibited medications and inadequate 
follow-up of hepatic events.
Patients will be analysed according to their randomized treatment group in previous studies 
1199.32/34, and overall.
The last available value between visit 1 and visit 2 (before first trial drug intake) will be 
considered as the baseline, for this extension trial.
The main statistical analyses as described below will be performed based on all data collected 
up to the third interim database lock date (see section 7.4). Afterwards, only adverse events 
and concomitant treatments listings will be provided.
7.3.1
Primary endpoint analyses

All patients in the treated set will be included in the safety analysis. The analyses of adverse 
events 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 (in extension study), based on BI Guideline “Handling of Extension Trials”. 
To this end, all adverse events will be classified according to the following trial periods:
previous trial, between-trials (from follow-up visit in previous trial up to date of informed 
consent in extension study), screening, on-treatment, post-treatment and post-study. 
All adverse events with an onset date from the date of the first dose in the extension trial up 
to 28 days after the end of trial treatment will be assigned to the on-treatment period. Other 
adverse events will be assigned to the previous trial, between-trials, screening, post-
treatment, or post-study period, as appropriate. 
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).
7.3.5
Pharmacokinetic analyses
Not applicable.
7.4.
INTERIM ANALYSES
A first interim analysis will be performed to include safety data from this study in the 
regulatory submission documents of nintedanib in IPF. The appropriate analyses will be 
detailed in the Trial Statistical Analysis Plan; the timing of the interim database lock will be 
defined to allow for presentation of the most complete data.
A second interim analysis will be performed after the last patient entered into the trial has 
reached 48 weeks of treatment. 
A third statistical analysis will be performed allowing the final assessment of all endpoints of 
this trial (refer to section 5.1). This will be the basis of the final Clinical Trial Report.
All the above mentioned analyses in Section 7.3 will be presented at each interim analysis.
Data collected after the third interim DBL date will only be listed once all patients have 
discontinued the trial and then incorporated in a revision of the CTR. Details will be provided 
in the TSAP.
7.5
HANDLING OF MISSING DATA
Missing or incomplete AE dates will be imputed according to BI rules. No imputation is 
planned for other safety criteria.

auditor will have access to all medical records, the investigator’s trial-related files and 
correspondence, and the informed consent documentation of this clinical trial.
To ensure good quality data, investigators and study site personnel will be familiarised with 
the study protocol, study procedures and principles of GCP during the Trial Initiation Visit. 
An Investigator Site File (ISF) with all necessary trial related documentation and handling 
procedures will be provided. 
A central laboratory will be used to collect, analyze and report the results of all blood 
samples.
To ensure standardization in FVC measurement, a central spirometry review is put in place: 
unique spirometry devices will be supplied to all participating sites. Two procedures will be 
performed using a CRO to ensure high quality of collected FVC measurements:

Quality Assurance (QA) process designed for providing feedback to the 
investigational site and the CRA on the quality of the data received from the site. 
During this process, a clinical specialist analyses and comments the data according to 
the ATS and study specific guidelines. A site gets an alert fax if all measurements of a 
patient during one visit are not acceptable. 

The Best Test Review (BTR) is designed to choose the best effort that will be used to 
represent the Best value for a particular test set. Only the acceptable efforts should be 
used to determine the best value. This choice is communicated to the Investigator 
whose confirmation is sought.
Data will be collected using a Remote Data Capture (RDC) system. Training will be provided 
to all investigators, coordinators and field monitors to ensure consistency and accuracy of the 
data. The data will be source verified by the field monitors.
Diagnoses and adverse events will be coded using MedDRA, and concomitant medications 
will be coded using WHO Drug Reference List. 
The data management procedures to ensure the quality of the data are described in detail in
the trial data management and analysis plan (TDMAP) available in the CTMF.
8.3

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 nintedanib this is the current version of the Investigator’s Brochure (U07-1248). The 
current version of this reference document is provided in the ISF. No AEs are classified as 
listed for 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

Clinical Evaluation of Liver Injury
10.1.1.1 Introduction
Alterations of liver laboratory parameters, as described in Section 4.2.1.2 and Section 5.3.6.1
(Protocol-Specified Significant Events), are to be further evaluated using the following 
procedures.
10.1.1.2 Procedures
Repeat the following laboratory tests: ALT, AST, and bilirubin (total and direct) - within 48 
to 72 hours and provide additional blood sample to the central laboratory for automatic reflex 
testing of the below listed laboratory parameters. Only in case whereby the central laboratory 
is not immediately available (e.g. if the logistics are such that the patient’s repeat specimen 
would not reach the central laboratory in a reasonable timeframe), ALT, AST, and bilirubin 
(total and direct) must be evaluated by local laboratory and results must be made available to 
the investigator and to BI as soon as possible.
If ALT and/or AST ≥3 fold ULN combined with an elevation of total bilirubin ≥2 fold ULN 
are confirmed, the laboratory parameters described below will be made available to the
investigator and to BI as soon as possible.
Clinical chemistry
Alkaline phosphatase, albumin, PT or INR, CK, CK-MB, ceruloplasmin, α-1 antitrypsin, 
transferrin, amylase, lipase, fasting glucose, cholesterol, triglycerides
Serology
Hepatitis A (Anti-IgM, Anti-IgG), Hepatitis B (HbsAg, Anti-HBs, DNA), Hepatitis C (Anti-
HCV, RNA if Anti-HCV positive), Hepatitis D (Anti-IgM, Anti-IgG), Hepatitis E (Anti-
HEV, Anti-HEV IgM, RNA if Anti-HEV IgM positive), Anti-Smooth Muscle antibody

6. INVESTIGATIONAL PLAN
Description of change
Was added:
6.2.5. Period after the database lock for the final 
analysis
After the database lock for the final analysis 
(refer to section 7.3) and once consent has been 
provided, the remaining patients in the trial 
(patients without access to nintedanib outside the 
clinical trial) will be offered continuation of 
treatment within the trial. This period will consist 
of study visits every 16 weeks (±2 weeks) where 
the following procedures will be conducted:
- Assessment of adverse events and concomitant 
therapy since last visit;
- Dispensation of trial drug.
Patients will continue to receive treatment until 
they meet a reason for discontinuation (refer to 
section 3.3.4) or until access to nintedanib is 
obtained outside the clinical trial. 
Dose reductions, interruptions and re-escalations 
are possible at any time during the scheduled 
study visits or between visits to manage adverse 
events.
End of treatment and follow up visits have to be 
performed to conclude the treatment period and 
trial participation.
Study procedures per visit are described in the 
Flow chart for patients who continue treatment 
after the database lock for the final analysis.
Investigators are encouraged to monitor liver 
function locally according to the 
recommendations provided in the Investigators 
Brochure.

the last patient entered into the trial has reached 
48 weeks of treatment. 
A third statistical analysis will be performed 
allowing the final assessment of all endpoints of 
this trial (refer to section 5.1). This will be the 
basis of the final Clinical Trial Report.
All the above mentioned analyses in Section 7.3 
will be presented at each interim analysis.
