Statistical methods
Preliminary pharmacokinetic analyses and simulations will be performed between 
trial part 1 and 2 as well as between part 2 and 3, if appropriate.
Relative bioavailability will be estimated by the ratios of the geometric means (test/ 
reference) for primary, secondary and further selected endpoints. Additionally, their 
two-sided 90% confidence intervals (CIs) will be provided. This method 
corresponds to the two one-sided t-test procedure, each at a 5% significance level. 
Since the main focus is on estimation and not testing, a formal hypothesis test and 
associated acceptance range is not specified. The statistical model will be an 
analysis of variance (ANOVA) on the logarithmic scale including effects for 
sequence, subject nested within sequence, period and treatment.
CIs will be calculated based on the residual error from the ANOVA.
Descriptive statistics will be calculated for all endpoints.

INTRODUCTION
Nintedanib is approved for 4 indications in 2 different therapeutic areas: IPF, progressive 
fibrosing ILD, and SSc-ILD in the respiratory therapeutic area as Ofev® and NSCLC for 
oncology as Vargatef®. In most countries, nintedanib is marketed under the trade name Ofev®
for the respiratory indications and as Vargatef® for oncology (NSCLC). Ofev® has been 
approved for treatment of idiopathic pulmonary fibrosis (IPF) since 2015 with a standard 
therapeutic dose of
 mg twice daily. Each treatment includes one
 mg Nintedanib soft 
capsule with an immediate release (IR) profile, which releases the total drug amount at once 
in the gut. Since the rapid local drug exposure is associated with increased gut toxicity and
adverse drug reactions, dose reduction to 
 mg twice daily is often necessary. Alteration in 
the capsule’s composition can lead to a modified release (MR) profile with a preferable 
steadier increase of local drug exposure. This is postulated to reduce local toxicity and 
increase overall tolerability of Nintedanib. Therefore, several MR formulations for 
Nintedanib have been developed and are planned to be tested in this clinical trial in healthy 
volunteers.
1.1
MEDICAL BACKGROUND
The major abnormality in fibrosing interstitial lung diseases (ILDs) is the disruption of the 
distal lung parenchyma. Although the pathogenesis, especially of the interstitial idiopathic 
pneumonias (including IPF), remains unknown, it is generally agreed that some form of 
injury of the alveolar epithelial cells initiates an inflammatory response coupled with 
inappropriate repair mechanisms. The initiating injury can be introduced via the airways (e.g. 
inhalation of mineral fibres or dust as in occupational diseases or sensitisation to inhaled 
allergens as in hypersensitivity pneumonitis) or via the circulation (e.g. connective tissue 
disease and drug-induced ILDs). The injury-repair process is reflected pathologically as 
inflammation, fibrosis or a combination of both. Fibrosing ILD, including IPF, is 
characterised by alveolar epithelial cell injury and subsequent dysregulated repair, 
characterised by excessive deposition of extracellular matrix and loss of normal parenchymal 
architecture and lung function. In IPF fibroblasts exhibit unregulated proliferation and 
differentiate into myofibroblasts. The latter is considered the hallmark cell in the 
development and establishment of lung fibrosis. Several growth factors are implicated in the 
proliferation, migration and transdifferentiation of the fibroblast and myofibroblast pool in 
pulmonary fibrosis.
For details on medical background refer to the current version of the Investigator’s Brochure
(IB) [c01783972].

DRUG PROFILE
Nintedanib is an oral small molecule triple receptor tyrosine kinase inhibitor that potently 
blocks vascular endothelial growth factor receptor 1-3, fibroblast growth factor receptor 1 
and 3, platelet derived growth factor receptor α/β, lymphocyte-specific tyrosine-protein 
kinase, tyrosine-protein kinase lyn, proto-oncogene tyrosine-protein kinase src, and colony 
stimulating factor 1 receptor. Nintedanib imparts its therapeutic effects through receptor

Clinical experience with Nintedanib in healthy volunteers
Nintedanib has been given as single doses of up to 
 mg (immediate release as marketed)
to healthy volunteers in 9 Phase I trials. In addition to the studies listed in the IB for fibrotic 
lung diseases [c01783972], one clinical bioequivalence trial (1199-0237; [c08883821]) was 
performed with oncologic Vargatef® (Nintedanib). In that trial, 70 healthy male volunteers 
were administered 2 single doses of 
 mg Nintedanib in fed state. Over all 9 trials, 
Nintedanib was given to approximately 240 healthy volunteers (including also study 
1199-0237 [c08883821]; excluding liver-impaired subjects in trial 1199-0200 [c03149997]). 
Single doses of Nintedanib were generally safe and well tolerated in healthy subjects. All

1.2.5
Residual Effect Period
The Residual Effect Period (REP) is the period after the last dose with measurable drug levels 
and/or pharmacodynamic effects still likely to be present. 
For this trial using 1 day treatment of 
 to (potentially) 
 mg Nintedanib in healthy male 
volunteers, a REP of 14 days is used, i.e. the individual subject’s end of trial is on day 15 
following dosing at the earliest and the washout between periods is at least 2 weeks (see 
Flow Chart).
1.3
RATIONALE FOR PERFORMING THE TRIAL
Ofev® soft capsules dissolve instantly within the gut environment and thus show an IR 
profile. However, the rapid increase of local drug exposure is associated with increased gut 
wall toxicity and gastro-intestinal adverse drug reactions such as diarrhoea. In contrast, a 
constant drug release over a longer period of time is hypothesized to improve gastro-
intestinal tolerability. Alteration in the shell’s composition may lead to such release profiles 
of Nintedanib and improve tolerability. Hence, several different tablets are to be 
manufactured to accomplish a MR of Nintedanib over 24 hours and match the equivalent 
drug exposures to that of the standard Ofev® treatment. Equivalent drug exposure can be 
presumed, if the MR formulation is within the same exposure corridor as Ofev®, i.e. equal 
total drug exposure (AUC0-24,ss), non-inferior minimum drug concentration (Cmin,ss) and non-
superior (Cmax,ss) peak drug concentration at steady state. Consequently, sufficient efficacy 
for the MR formulation can be assumed without explicit testing. Since only single dose 
administration is planned for the MR formulations, the concentration after 24 hours post dose 
will be measured (C24), while Cmin,ss as well as Cmax,ss for steady state may be simulated in a 
respective model at the end of trial (e.g. after database lock).
1.4
BENEFIT – RISK ASSESSMENT
Participation in this study is without any (therapeutic) benefit for healthy subjects. Their 
participation in the study, however, is of major importance to improve overall tolerability and 
treatment success of patients with IPF and ILD. The subjects are exposed to the risks of the 
study procedures and the risks related to the exposure to the trial medication.
Procedure-related risks
The use of an indwelling venous catheter or venepuncture for e.g. blood sampling may result 
in mild bruising, and in rare cases, in transient inflammation of the wall of the vein, or nerve 
injury, potentially resulting in paraesthesia, reduced sensibility, and/or pain for an indefinite 
period.
The total volume of blood withdrawn per subject during the entire study will not exceed a 
volume of 550 mL in a 4-week period. No health-related risk to healthy subjects is expected 
from withdrawal of this volume of blood.
Electrocardiogram (ECG) stickers on the subjects’ chests and limbs may cause some local 
irritation and may be uncomfortable to remove but subjects will be closely monitored to 
ensure any local irritation does not persist.

COVID-19 pandemic
Based on the pharmacological mechanism and existing non-clinical, clinical and post-
marketing data there is no indication that treatment with Nintedanib may increase the risk of 
infection with or progression of SARS-CoV-2 infection. Participation in this trial may 
increase the risk of COVID-19 exposure due to travels to the study site and completion of 
protocol-defined procedures at the site. A risk management plan has been set up at the 
clinical site that details precautionary measures (e.g., hygiene rules, wearing of face masks, 
physical distancing) and screening for SARS-CoV-2 infection.
General risk mitigation against COVID-19 will be implemented in accordance with 
 monitoring and prevention control measures.
COVID-19 testing may be performed based on current infection rates and availability of tests. 
If required, testing will comprise an antibody blood test performed at screening, and an 
antigen polymerase chain reaction (PCR) test or other antigen test performed at screening, the 
day before admission to each treatment period, and discharge or the day before discharge 
from each treatment period. Testing time points may be changed and additional time points 
may be added throughout the study as required. The decision on COVID-19 testing and the 
definition of the testing time points will be agreed by the study team and documented in the 
Investigator Site File (ISF) via the Clinical Kick-Off Meeting minutes. The risk mitigation 
measures, where applicable, will be amended based on emerging government guidance.
COVID-19 Vaccine-Related Risk
Approved (including health authority conditional marketing optimization) COVID-19 
vaccines eg killed, inactivated, peptide DNA and RNA vaccines may be permitted according 
to the investigator’s discretion and as per local guidance. Based on the mechanism of action 
of Nintedanib, as a tyrosine kinase inhibitor, there is no perceived impact on the safety of the 
study subjects or on the study objectives for subjects who may receive these vaccines (either 
first or second doses). It is also very unlikely that administration of Nintedanib would 
interfere with COVID-19 vaccination response; however, no specific preclinical or clinical 
investigations have been conducted at this point with Nintedanib.
The emerging safety and efficacy data from millions of vaccinated people, many of whom are 
elderly and with underlying health conditions and taking multiple concomitant medications, 
indicate that these vaccines have an excellent safety and efficacy record. In the broader 
interests of society and to limit the extent of the global pandemic, it is important that subjects 
should receive a vaccine when it is offered to them.
Summary of benefit-risk assessment
Taking into account the safety profile of Nintedanib, the safety measures in this trial, and the 
need for effective treatment of fibrosing interstitial lung diseases, the expected benefit of this 
trial outweighs the potential risks and justifies exposure of healthy human subjects.

TRIAL OBJECTIVES AND ENDPOINTS
2.1
MAIN OBJECTIVES, PRIMARY AND SECONDARY ENDPOINTS
2.1.1
Main objectives
The main objective of this trial is to assess single dose drug exposure of several newly 
developed MR formulations of Nintedanib (MR1 and MR2 prototypes) compared to 
mg 
of Ofev® IR, twice daily (Reference, R) following oral administration.
In trial part 1, four MR prototypes of Nintedanib (prototypes 1 and 2, each with a fast and 
slow in-vitro dissolution rate) will be tested. Based on pharmacokinetic results, one MR 
formulation may be selected for subsequent optimisation in dissolution and dose rate to 
ultimately match exposure corridor of Ofev® IR. The optimised MR formulation will then be 
evaluated in optional trial part 2. If the pre-selected MR formulation is still not matching the 
Ofev® IR exposure corridor, an optional trial part 3 is conducted after further optimisation of 
dissolution profile and dose. 
Plasma drug exposure and PK parameters will be assessed after each trial part and MR 
formulations adjusted accordingly (e.g. coating compositions, drug dose) for the following 
trial part.
2.1.2
Primary endpoints
The following pharmacokinetic parameters will be determined for Nintedanib:
∀
AUC0-∞(area under the concentration-time curve of the analyte in plasma over the 
time interval from 0 [first dose] extrapolated to infinity which includes also the 
second Nintedanib dose of the day)
2.1.3
Secondary endpoint
The following pharmacokinetic parameter will be determined for Nintedanib:
∀
AUC0-tz (area under the concentration-time curve of the analyte in plasma over the 
time interval from 0 to the last quantifiable data point)
∀
Cmax (maximum measured concentration of the analyte in plasma within the 24h 
dosing interval)
∀
C24 (concentration of the analyte in plasma 24 h after the (first) dose)

DESCRIPTION OF DESIGN AND TRIAL POPULATION
3.1
OVERALL TRIAL DESIGN AND PLAN
The study will be performed in healthy male subjects as an open-label, randomised, single-
dose study in up to three trial parts in order to compare each of the test treatments (MR1, 
MR2, MRX) to the respective reference treatment R. The subjects will be randomly allocated 
to three treatment sequences in trial part 1 and 2 (Latin square design). There will be a 
washout period of at least 14 days between the treatments, i.e. the morning dose in the 
preceding treatment period and the morning dose in the following treatment period are 
separated by at least 14 days.
For illustration of the overall study design, refer to Figure 3.1: 1. An overview of all relevant 
trial activities is provided in the Flow Chart. For visit schedule and details of trial procedures 
at selected visits, refer to Sections 6.1 and 6.2, respectively.
Trial part 1
Trial part 1 (n=30) will be performed with two parallel groups (cohort 1 and 2, each n=15), 
each in a randomised three-period crossover design in order to compare MR1 test treatments 
to the reference treatment R (for trial part 1A) as well as MR2 test.
These treatments will be administered after light fed conditions (light breakfast, additionally 
light dinner in Reference) and in one of the following three sequences for each group:

A single dose (test treatments) and a b.i.d. dose for one day (reference treatments), 
respectively will be administered as depicted in Figure 3.1: 1 above and Table 4.1.4: 1.
Decision point: either (a) stop here or (b) proceed to trial part 2 with one selected formulation 
MR1 or MR2 and release profile in order to optimise dose.
In-study decisions will be made by the safety advisory committee (SAC), which will always 
comprise the investigator, the sponsor’s representative medical monitor or the sponsor’s 
medically qualified designee who is familiar with the study protocol and IB, and a PK expert 
where appropriate. Formulation and dose selection will only be made after a complete review 
of all data collected from the previous dose group. 
The following in-study decisions will be made:
∀
Formulation selection
∀
Dose selection (please see Section 4.1.2)
Decision rules: The decision will be based on data of all evaluable subjects (see Section 7.3
PKS definition) in each of trial parts 1A as well as 1B and will include the assessment of (i) 
safety parameters (e.g., AE, ECG, vital signs and safety laboratory data) up to 72 h post-dose, 
(ii) preliminary pharmacokinetic analysis up to 72 h post-dose.
Criteria to stop particular MR formulation after trial part 1 will be in case one of the below 
points holds true:
∀
MR formulation is considered not to be safe (see Section 3.3.4.3 for stopping criteria)
∀
the 90% confidence interval (CI) of the AUC0-∞gMean ratio between a MR 
formulation and Ofev® IR lies completely outside of 95-105% and further 
optimisation of the formulation with regards to dose and dissolution rate is not 
expected to improve pharmacokinetic properties, accordingly
∀
the lower 90% CI of the Cmax gMean ratio between a MR formulation and Ofev® IR is 
>105% and further optimisation of the formulation with regards to dose and 
dissolution rate is not expected to improve pharmacokinetic properties, accordingly
∀
the upper 90% CI of the C24 gMean ratio between a MR formulation and Ofev® IR is 
<95% and further optimisation of the formulation with regards to dose and dissolution 
rate is not expected to improve pharmacokinetic properties, accordingly
In case no MR formulation fulfils the criteria above the following rule will help in deciding
which MR formulation to develop further:
∀
for AUC0-∞, Cmax and C24 the adjusted gMean ratios for each MR formulation as well 
as the gSE of the difference will be calculated coming from the defined ANOVA 
model in Section 7.3.1.
∀
for an adjusted gMean ratio >1 the decision value (DV) is defined by gMean 
ratio*gSE

Decision point: either (a) stop here or (b) proceed to trial part 3 with the optimised 
formulation in order to optimise release rate and dose.
In-study decisions will be made by the SAC.
Decision rules: The decision will be based on data of all evaluable subjects and will include 
the assessment of (i) safety parameters (e.g. AE, ECG, vital signs and safety laboratory data) 
up to 72 h post-dose, (ii) preliminary pharmacokinetic analysis up to 72 h post-dose.
Criteria to stop or to continue particular MR formulation after trial part 2 will be the same as 
for Part 1 (see above).
Decision outcome: If further optimisation is considered necessary and possible for the 
selected MR formulation(s) tested in part 2, another prototype will be developed and further 
tested in trial part 3.
Trial part 3 (optional)
Trial part 3 (cohort 4, n=14) will be performed as a randomised two-period crossover design

A single dose (test treatment) and a b.i.d. dose for one day (reference treatment), respectively
will be administered as depicted in Figure 3.1: 1 and Table 4.1.4: 1.
3.2
DISCUSSION OF TRIAL DESIGN, INCLUDING THE CHOICE OF 
CONTROL GROUP
3.2.1
Discussion of study design
The Clinical Trial Authorisation (CTA) application for this study describes a flexible protocol 
design using the concept of formulation design space to allow decision-making in response to 
interim pharmacokinetic (PK) observations. The principles of a flexible protocol were 
discussed and agreed with the Medicines and Healthcare products Regulatory Agency 
(MHRA) at a Scientific Advice Meeting between the MHRA and 
formerly 
Pharmaceutical Profiles).
Based upon the concept of formulation design space/a bracketed dose approach, specific 
IMPs are not detailed within the Investigational Medicinal Product Dossier (IMPD) but rather 
a defined dose range of formulation inputs and corresponding performance outputs are 
described and justified based on in vitro studies. The chosen formulation from within the 
approved design space for the first prototype to be dosed will be documented in a decision 
document and approved by the sponsor and a 
representative ahead of manufacture.
The open-label treatment is not expected to bias results, since the study endpoints are derived 
from measurement of plasma concentrations of the analyte.
For relative bioavailability trials, the crossover design is preferred because of its efficiency: 
since each subject serves as his own control, the comparison between formulations is based 
on an intra-subject comparison, thus removing inter-subject variability from the comparison 
between formulations [R94-1529].
3.2.2
Rationale for decision rules
The rationale for performing this trial is to identify an MR formulation that still results in 
Nintedanib exposure within the corridor of standard Ofev® IR treatment.
Rules, described in Section 3.1, allow to make a decision whether one of the tested 
formulations meets the requirements after trial part 1, or whether it can be improved within 
this trial in part 2 and/ or part 3. Rules would also guide the termination of the process, either 
after trial part 1 or trial part 2, if no successful formulation was to be achieved.
3.3
SELECTION OF TRIAL POPULATION
A log of all subjects enrolled into the trial (i.e. who have signed informed consent) will be 
maintained in the ISF irrespective of whether they have been treated with investigational drug 
or not. It is planned that 30 or 59 (optional) healthy male subjects will enter the study. They 
will be recruited from the volunteers' pool of the trial site.

 must have a full medical history from each subject’s general practitioner 
(GP) within the last 24 months, prior to enrolment in the study. Before subjects are admitted 
to the clinical unit, The Over Volunteering Prevention System (TOPS) will be checked to 
ensure that each subject has not participated in a study at another site within at least 90 days 
of the dosing date.
As this is a Phase I study assessing the PK, relative bioavailability and safety of Nintedanib, 
the most relevant population is healthy volunteers. Subjects who are non-smokers without a 
history of alcohol or drug abuse or regular co-medication are proposed to avoid interaction on 
drug metabolism and to avoid non-compliance. 
Considering the teratogenic potential of Nintedanib, only male subjects will be included. 
(refer also to [R21-3511]).
3.3.1
Main diagnosis for trial entry
The study will be performed in healthy subjects.
3.3.2
Inclusion criteria
Subjects will only be included in the trial if they meet the following criteria:
1. Healthy male subjects (Caucasian and Black only) according to the investigator’s 
assessment, based on a complete medical history including a physical examination, vital 
signs (BP, PR), 12-lead ECG and clinical laboratory tests 
2. Age of 18 to 55 years (inclusive)
3. BMI of 18.5 to 29.9 kg/m2 (inclusive) and absolute body weight of at least 65 kg
4. Signed and dated written informed consent prior to admission to the study, in accordance 
with GCP and local legislation
5. Non-smokers for at least 6 months
6. Subjects who are sexually active must use with their partner, highly effective 
contraception from the time of administration of trial medication until 30 days after 
administration of trial medication. Adequate methods are:
∀

Subjects are required to use condoms to prevent unintended exposure of the partner (both, 
male and female) to the study drug via seminal fluid. Male subjects should use a condom 
throughout the study and for 30 days after last IMP administration. Alternatively, true 
abstinence is acceptable when it is in line with the subject’s preferred and usual lifestyle. If a 
subject is usually not sexually active but becomes active with their partner, they must comply 
with the contraceptive requirements detailed above.
Male subjects should not donate sperm for the duration of the study and for at least 30 days 
after last IMP administration.
Male subjects with pregnant or lactating partners are allowed.

3.3.4
Withdrawal of subjects from treatment or assessments
Subjects may discontinue trial treatment or withdraw consent to trial participation as a whole 
(‘withdrawal of consent’) with very different implications; please see Sections 3.3.4.1 and 
3.3.4.2 below.
If a subject is removed from or withdraws from the trial prior to the first administration of 
trial medication, the data of this subject will not be entered in the case report form (CRF) and 
will not be reported in the clinical trial report (CTR). If a subject is removed from or 
withdraws from the trial after the first administration of trial medication, this will be 
documented and the reason for discontinuation must be recorded in the CRF; in addition, the 
data will be included in the CRF and will be reported in the CTR. At the time of 
discontinuation, a complete end of trial examination will be performed, if possible, and the 
information will be recorded in the CRF. If the discontinuation occurs before the end of the 
REP (see Section 1.2.3), the discontinued subject should if possible be questioned for AEs 
and concomitant therapies at or after the end of the REP in order to ensure collection of AEs 
and concomitant therapies throughout the REP, if not contrary to any consent withdrawal of 
the subject.
3.3.4.1
Discontinuation of trial treatment
An individual subject will discontinue trial treatment if:
∀
The subject wants to discontinue trial treatment, without the need to justify the decision
∀
The subject has repeatedly shown to be non-compliant with important trial procedures 
and, in the opinion of both, the investigator and sponsor representative, is not willing or 
able to adhere to the trial requirements in the future.
∀
The subject has a concurrent illness 
 or needs to take 
concomitant medication that interferes with the investigational medicinal product or other 
trial treatment
∀
The subject can no longer receive trial treatment for medical reasons (such as surgery, 
adverse events [AEs], or diseases)
∀
The subject experiences a serious or severe AE including but not limited to:
∀
an elevation of AST and/or ALT ≥3-fold ULN and an elevation of total bilirubin ≥2-
fold ULN (measured in the same blood sample) and/or needs to be followed up 
according to the DILI checklist provided in the ISF
∀
corrected QT interval by Fridericia’s formula (QTcF) of >500 msec or increase in 
QTcF interval of >60 msec from baseline (confirmed following a repeat ECG)
In addition to these criteria, the investigator may discontinue subjects at any time based on 
his or her clinical judgment.

Even if the trial treatment is discontinued, the subject remains in the trial and, given his 
agreement, will undergo the procedures for early treatment discontinuation and follow up as 
outlined in the Flow Chart and Section 6.2.3.
3.3.4.2
Withdrawal of consent to trial participation
Subjects may withdraw their consent to trial participation at any time without the need to 
justify the decision. If a subject wants to withdraw consent, the investigator should be 
involved in the discussion with the subject and explain the difference between trial treatment 
discontinuation and withdrawal of consent to trial participation, as well as explain the options 
for continued follow up after trial treatment discontinuation, please see Section 3.3.4.1 above
3.3.4.3
Discontinuation of the trial by the sponsor
Boehringer Ingelheim reserves the right to discontinue the trial at any time for any of the 
following reasons:
1. Failure to meet expected enrolment goals overall
2. New toxicological findings, serious adverse events, or any safety information invalidating
the earlier positive benefit-risk-assessment. More specifically, the trial will be terminated 
or halted if more than 50% of the subjects have drug-related and clinically relevant 
adverse events of moderate or severe intensity, or if at least 1 drug-related serious adverse 
event is reported, or if severe non-serious adverse reactions (i.e. severe non-serious AE 
considered as at least possibly related to the IMP administration) in two subjects in the 
same cohort, independent of within or not within the same system organ class. 
Relatedness to IMP will be determined by the investigator.
3. Violation of GCP, or the CTP, or the contract with BI impairing the appropriate conduct 
of the trial
4. The sponsor decides to discontinue the further development of the investigational product
If the study is halted, a temporary halt will be submitted to the Medicines and Healthcare 
products Regulatory Agency (MHRA) and ethics committee (EC) in the form of a substantial 
amendment. The study may be resumed or terminated; however, it will not be resumed until a 
further substantial amendment to resume the study is submitted and approved by MHRA and 
EC.
The investigator / trial site will be reimbursed for reasonable expenses incurred in case of 
trial termination (except if item 3 applies).
3.3.5
Replacement of subjects
In case more than 3 subjects in one of the parallel groups of trial part 1 or in trial parts 2 and 
3 do not complete the trial, the Clinical Trial Leader together with the Trial 
Pharmacokineticist and the Trial Statistician are to decide, if and how many subjects will be

replaced. A replacement subject will be assigned a unique trial subject number and will be 
assigned to the same treatment as the subject he replaces.
It is planned to have at least 12 evaluable subjects per crossover part. Up to 3 replacement 
subjects may be used per cohort. The maximum number of subjects that may be dosed is 18, 
the cohort size of 15 plus 3 replacements.

investigator or designee must verify that all unused or partially used drug supplies have been 
returned by the clinical trial subject and that no remaining supplies are in the investigator’s 
possession.
All unused medication will be disposed of locally by the trial site upon written authorisation 
of the trial clinical monitor. Receipt, usage and disposal of trial medication must be 
documented on the appropriate forms. Account must be given for any discrepancies.
4.2
OTHER TREATMENTS, EMERGENCY PROCEDURES, 
RESTRICTIONS
4.2.1
Other treatments and emergency procedures
There are no special emergency procedures to be followed. No additional treatment is 
planned. However, if adverse events require treatment, the investigator can authorise 
symptomatic therapy. In those cases, subjects will be treated as necessary and, if required, 
kept under supervision at the trial site or transferred to a hospital until all results of medical 
evaluations are acceptable.
4.2.2
Restrictions
4.2.2.1
Restrictions regarding concomitant treatment
In principle, no concomitant therapy is allowed. All concomitant or rescue therapies will be 
recorded (including time of intake on study days) on the appropriate pages of the CRF.
Drugs with a known hepatotoxicity profile (e.g., paracetamol or diclofenac) or medication 
with an increased risk for bleeding (e.g. acetylsalicylic acid) should be avoided during the 
entire study; if necessary, short term use of ibuprofen is acceptable.
Known inhibitors or inducers of P-gp and CYP3A activity should be avoided during the 
entire study due to drug-drug interaction potential with Nintedanib. Drugs that cause QT/QTc 
interval prolongation should also be avoided.
4.2.2.2
Restrictions on diet and life style
While admitted to the trial site, the subjects will be instructed not to consume any foods or 
drinks other than those provided by the staff. Standardised meals will be served at the times
indicated in the Flow Chart. No food is allowed for at least 4 h after drug intake in the 
morning.
From 1 h before drug intake in the morning until lunch, fluid intake is restricted one cup of 
water without sugar served with breakfast (see Section 4.1.4), the water administered with the 
drug, and an additional 240 mL of water at 2 h and 4 h post-dose (mandatory for all subjects). 
From lunch until 24 h post-dose, total fluid intake is restricted to 3000 mL.
Poppy-seeds containing foods should not be consumed starting 3 days before screening and
admission to each treatment period to avoid false-positive results in the drug screen.

Alcoholic beverages are not permitted from 3 days before first drug administration until the 
end of trial examination.
Grapefruits, Seville oranges (sour or bitter oranges) and their juices, and dietary supplements 
and products containing St. John's wort (Hypericum perforatum) are not permitted from 7 
days before the first administration of trial medication until after the last PK sample of the 
study is collected.
Methylxanthine-containing drinks or foods (such as coffee, tea, cola, energy drinks, or 
chocolate) are not allowed during inhouse stays.
Smoking is not allowed during in-house confinement.
Excessive physical activity (such as competitive sport) should be avoided from 7 days before 
the first administration of trial medication until the end of trial examination.
4.3
TREATMENT COMPLIANCE
Compliance will be assured by administration of all trial medication in the study centre under 
supervision of the investigating physician or a designee. The measured plasma concentrations 
of trial medication will provide additional confirmation of compliance.
Subjects who are non-compliant (for instance, who do not appear for scheduled visits or 
violate trial restrictions) may be removed from the trial and the CRF will be completed 
accordingly (for further procedures, please see Section 3.3.4.1).

ASSESSMENTS OF SAFETY
5.2.1
Physical examination
At screening, the medical examination will include demographics, height and body weight, 
smoking and alcohol history (results not mandatory to be entered into CRF or to be reported), 
relevant medical history and concomitant therapy, review of inclusion and exclusion criteria, 
review of vital signs (BP, PR), 12-lead ECG, laboratory tests (including drug screening), and 
a physical examination. At the end of trial examination, it will include review of vital signs, 
12-lead ECG, laboratory tests, and a physical examination including determination of weight.
5.2.2
Vital signs
Systolic and diastolic blood pressures (BP) as well as pulse rate (PR) or heart rate (heart rate 
is considered to be equal to pulse rate) will be measured by a blood pressure monitor (e.g., 
DASH 4000) at the times indicated in the Flow Chart, after subjects have rested for at least 5 
min in a supine position. All recordings should be made using the same type of blood 
pressure recording instrument on the same arm, if possible. If required, vital signs assessment 
can be repeated.
In addition, oral body temperature may be measured at any time at the discretion of the 
investigator. These measurements will not be recorded in the eCRF.
5.2.3
Safety laboratory parameters
For the assessment of laboratory parameters, blood and urine samples will be collected by the 
trial site at the times indicated in the Flow Chart after the subjects have fasted for at least 
10 h. For retests, at the discretion of the investigator or designee, overnight fasting is not 
required.
The parameters that will be determined are listed in Tables 5.2.3: 1 and 5.2.3: 2. Reference 
ranges will be provided in the ISF, Section 10.
Manual differential white blood cell count or urine sediment examinations will only be 
performed if there is an abnormality in the automatic blood cell count or in the urinalysis, 
respectively.

time during the study at the discretion of an investigator or designee. The results will not be 
included in the CTR.
The laboratory tests listed in Tables 5.2.3: 1 and 5.2.3: 2 will be performed at
 
 with the exception 
of drug screening tests. These tests will be performed at the trial site using an Alere Drug 
Screen Test Cup, respectively, or comparable test systems. Urinalysis assessments also will 
be performed at the trial site using, e.g., Combi-Screen® Urine Test Strips. If urine 
microscopy is required, a sample will be shipped to 
” for analysis.
Laboratory data will be transmitted electronically from the laboratory to the trial site.
5.2.4
Electrocardiogram
Twelve-lead ECGs (I, II, III, aVR, aVL, aVF, V1 - V6) will be recorded using a
computerised electrocardiograph (e.g., Mortara ELI 250c) at the times provided in the 
Flow Chart.
To achieve a stable heart rate at rest and to assure high quality recordings, the site personnel 
will be instructed to assure a relaxed and quiet environment, so that all subjects are at 
complete rest.
All ECGs will be recorded for a 10 sec duration after subjects have rested for at least 5 min in 
a supine position. ECG assessment will always precede all other study procedures scheduled 
for the same time to avoid compromising ECG quality.

All locally printed ECGs will be evaluated by the investigator or a designee. Abnormal 
findings will be reported as AEs (during the trial) or baseline conditions (at screening) if 
assessed to be clinically relevant by the investigator. Any ECG abnormalities will be 
carefully monitored and, if necessary, the subject will be removed from the trial and will 
receive the appropriate medical treatment.
ECGs may be repeated for quality reasons (for instance, due to alternating current artefacts, 
muscle movements, or electrode dislocation) and the repeated ECG will be used for analysis. 
Additional (unscheduled) ECGs may be collected by the investigator for safety reasons. 
All ECGs will be stored as paper copies.

Other safety parameters
Not applicable.

Assessment of adverse events
5.2.6.1
Definitions of adverse events
5.2.6.1.1
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.
The following should also be recorded as an AE in the CRF and BI SAE form (if applicable):
∀
Worsening of the underlying disease or of other pre-existing conditions 
∀
Changes in vital signs, ECG, physical examination, and laboratory test results, if they 
are judged clinically relevant by the investigator
If such abnormalities already pre-exist prior to trial inclusion, they will be considered as 
baseline conditions and should be collected in the eCRF only.
5.2.6.1.2
Serious adverse event
A serious adverse event (SAE) is defined as any AE which fulfils at least one of the 
following criteria:
∀
Results in death
∀
Is life-threatening, which refers to an event in which the patient was at risk of death 
at the time of the event; it does not refer to an event that hypothetically might have 
caused death if more severe
∀
Requires inpatient hospitalisation
∀
Requires prolongation of existing hospitalisation
∀
Results in persistent or significant disability or incapacity

∀
Is a congenital anomaly/birth defect
∀
Is deemed serious for any other reason if it is an important medical event when based 
upon appropriate medical judgment which may jeopardise 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
5.2.6.1.3
AEs considered ‘Always Serious’
Cancers of new histology and exacerbations of existing cancer must be classified as a serious 
event regardless of the time since discontinuation of the trial medication and must be reported 
as described in Section 5.2.6.2, subsections ‘AE Collection’ and ‘AE reporting to sponsor 
and timelines’.
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 
defined above.
These events should always be reported as SAEs as described above.
5.2.6.1.4
Adverse events of special interest
The term adverse events of special interest (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. AESIs need to be reported to the sponsor’s 
Pharmacovigilance Department within the same timeframe that applies to SAEs, please see 
Section 5.2.6.2.2.
The following are considered as AESIs:
∀
Hepatic injury
A hepatic injury is defined by the following alterations of hepatic laboratory 
parameters: 
o
An elevation of AST (aspartate transaminase) and/or ALT (alanine 
transaminase) ≥3-fold ULN combined with an elevation of total bilirubin 
≥2-fold ULN measured in the same blood sample, or
o
Aminotransferase (ALT, and/or AST) elevations ≥10 fold ULN
These lab findings constitute a hepatic injury alert and the subjects 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 that 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.
5.2.6.1.5
Intensity (severity) of AEs
The intensity (severity) of the AE should be judged based on the following:
Mild:
Awareness of sign(s) or symptom(s) that is/are easily tolerated
Moderate:
Sufficient discomfort to cause interference with usual activity
Severe:
Incapacitating or causing inability to work or to perform usual activities
5.2.6.1.6
Causal relationship of AEs
Medical 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 
could be:
∀
The event is consistent with the known pharmacology of the drug 
∀
The event is known to be caused by or attributed to the drug class
∀
A plausible time to onset of the event relative to the time of drug exposure
∀
Evidence that the event is reproducible when the drug is re-introduced
∀
No medically sound alternative aetiologies that could explain the event (e.g. pre-
existing or concomitant diseases, or co-medications)
∀
The event is typically drug-related and infrequent in the general population not 
exposed to drugs (e.g. Stevens-Johnson syndrome)
∀
An indication of dose-response (i.e. greater effect size if the dose is increased, smaller 
effect size if dose is reduced)
Arguments that may suggest that there is no reasonable possibility of a causal relationship 
could be:
∀
No plausible time to onset of the event relative to the time of drug exposure is evident 
(e.g. pre-treatment cases, diagnosis of cancer or chronic disease within days / weeks 
of drug administration; an allergic reaction weeks after discontinuation of the drug 
concerned)
∀
Continuation of the event despite the withdrawal of the medication, taking into 
account the pharmacological properties of the compound (e.g. after 5 half-lives). Of 
note, this criterion may not be applicable to events whose time course is prolonged 
despite removing the original trigger
∀
Additional arguments amongst those stated before, like alternative explanation (e.g. 
situations where other drugs or underlying diseases appear to provide a more likely 
explanation for the observed event than the drug concerned)

5.2.6.2
Adverse event collection and reporting
5.2.6.2.1
AE collection
Upon enrolment into a trial (written informed consent), the subject’s baseline condition is 
assessed (for instance, by documentation of medical history/concomitant diagnoses), and 
relevant changes from baseline are noted subsequently. 
Subjects will be required to report spontaneously any AEs as well as the time of onset, end
time, and intensity of these events. In addition, each subject will be regularly assessed by the 
medical staff throughout the clinical trial and whenever the investigator deems necessary. As 
a minimum, subjects will be questioned for AEs (and concomitant therapies) at the time 
points indicated in the Flow Chart. Assessment will be made using non-specific questions 
such as ‘How do you feel?’. Specific questions will be asked wherever necessary in order to 
more precisely describe an AE.
A carefully written record of all AEs shall be kept by the investigator in charge of the trial. 
Records of AEs shall include data on the time of onset, end time, intensity of the event, and 
any treatment or action required for the event and its outcome.
The following must be collected and documented on the appropriate CRF(s) by the 
investigator:
∀
From signing the informed consent onwards until an individual subject’s end of trial: 
o
All AEs (serious and non-serious)
o
The only exception to this rule are AEs (serious and non-serious) in Phase I 
trials in healthy volunteers, when subjects discontinue from the trial due to 
screening failures prior to administration of any trial medication. In these 
cases, the subjects’ data must be collected at trial site but will not be entered in 
the CRF or trial database and will not be reported in the CTR.
∀
After the individual subject’s end of trial: 
o
The investigator does not need to actively monitor the subject for AEs but 
should only report any occurrence of cancer and related SAEs of which the 
investigator may become aware of by any means of communication, e.g. 
phone call. Those AEs should, however, not be reported in the CRF.

5.2.6.2.2
AE reporting to the sponsor and timelines
The Investigator must report SAEs, and non-serious AEs which are relevant for the reported 
SAE, on the BI SAE form via fax immediately to the sponsor’s unique entry point (country 
specific contact details will be provided in the ISF). The same timeline applies if follow-up 
information becomes available. In specific occasions the Investigator could inform the 
sponsor upfront via telephone. This does not replace the requirement to complete and fax the 
BI SAE form.
With receipt of any further information to these events, a follow-up SAE form has to be 
provided. For follow-up information, the same rules and timeline apply as for initial 
information.
5.2.6.2.3
Information required
All (S)AEs, including those persisting after the individual subject’s end of trial, must be 
followed up until they have resolved, have been sufficiently assessed as ‘chronic’ or ‘stable’, 
or no further information can be obtained.
5.3
DRUG CONCENTRATION MEASUREMENTS AND 
PHARMACOKINETICS
5.3.1
Assessment of pharmacokinetics
For the assessment of pharmacokinetics, blood samples will be collected at the time points / 
time intervals indicated in the Flow Chart. The actual sampling times will be recorded and 
used for determination of pharmacokinetic parameters. 
5.3.2
Methods of sample collection
5.3.2.1
Blood sampling for pharmacokinetic analysis
For quantification of Nintedanib concentrations in plasma, approximately 2.7 mL of blood 
will be drawn from an antecubital or forearm vein into an K2-EDTA (dipotassium 
ethylenediaminetetraacetic acid)-anticoagulant blood drawing tube at the times indicated in 
the Flow Chart. Blood will be withdrawn by means of either an indwelling venous catheter or 
by venepuncture with a metal needle. The first 0.5 mL withdrawn by an indwelling cannula 
will be discarded.
The EDTA-anticoagulated blood samples will be centrifuged for approximately 10 min at 
approximately 2000 g to 4000 g and at 4 to 8 °C. Two plasma aliquots will be obtained and 
stored in polypropylene tubes. The first aliquot should contain at least 0.5 mL of plasma. The 
process from blood collection until transfer of plasma aliquots into the freezer should be 
completed in less than 60 min with interim storage of blood samples and aliquots in ice water 
or on ice. The time each aliquot was placed in the freezer will be documented. Until transfer 
on dry ice to the analytical laboratory, the aliquots will be stored upright at 
approximately -20°C or below at the trial site. The second aliquot will be transferred to the 
analytical laboratory after the bioanalyst has acknowledged safe arrival of the first aliquot. At

the analytical laboratory, the plasma samples will be stored at approximately -20°C or below 
until analysis.
At a minimum, the sample tube labels should list BI trial number, subject number, visit, and 
planned sampling time. 
After completion of the trial, the plasma samples may be used for further methodological 
investigations (e.g. for stability testing or assessment of metabolites. However, only data 
related to the analyte and/or its metabolite(s) including anti-drug antibodies (if applicable) 
will be generated by these additional investigations. The study samples will be discarded after 
completion of the additional investigations but not later than 5 years after the CTR is 
archived.
5.3.4
Pharmacokinetic - pharmacodynamic relationship
No analysis of the relationship between pharmacokinetic and pharmacodynamic parameters is 
planned for this trial.

BIOBANKING
Not applicable.
5.6
APPROPRIATENESS OF MEASUREMENTS
All measurements performed during this trial are standard measurements and will be 
performed in order to monitor subjects’ safety and to determine pharmacokinetic parameters 
in an appropriate way. The scheduled measurements will allow monitoring of changes in vital 
signs, standard laboratory values, and ECG parameters that might occur as a result of 
administration of trial medication. The safety assessments are standard, are accepted for 
evaluation of safety and tolerability of an orally administered drug, and are widely used in 
clinical trials. The pharmacokinetic parameters and measurements outlined in Section 5.3 are 
generally used assessments of drug exposure.

INVESTIGATIONAL PLAN
6.1
VISIT SCHEDULE
Exact times of measurements outside the permitted time windows will be documented. The 
acceptable time windows for screening, the end of trial examination, and measurements and 
assessments scheduled to occur ‘before’ trial medication administration in the morning of 
Day 1 are provided in the Flow Chart.
If not stated otherwise in the Flow Chart, the general acceptable deviation from the scheduled 
time for vital signs, ECG, and laboratory tests will be ± 30 min.
The acceptable deviations from the nominal urine sampling time points for urinalysis are:
∀
The pre-dose urine sample will be the first void of the day or a sample collected ≤3 h 
before dosing
∀
Post-dose urine samples will be taken ± 2 h from the nominal urine sampling time
If scheduled in the Flow Chart at the same time as a meal, blood sampling, vital signs, and 
12-lead ECG recordings have to be done first. Furthermore, if several measurements 
including venepuncture are scheduled for the same time, venepuncture should be the last of 
the measurements due to its inconvenience to the subject and possible influence on 
physiological parameters.
For planned blood sampling times, refer to the Flow Chart. While these nominal times should 
be adhered to as closely as possible, the actual sampling times will be recorded and used for 
the determination of pharmacokinetic parameters.
If a subject misses an appointment, it will be rescheduled if possible. The relevance of 
measurements outside the permitted time windows will be assessed no later than at the Report 
Planning Meeting.
6.2
DETAILS OF TRIAL PROCEDURES AT SELECTED VISITS
6.2.1
Screening period
After having been informed about the trial, all subjects will provide written informed consent 
in accordance with GCP and local legislation prior to enrolment in the study.
For information regarding laboratory tests (including drug and virus screening), ECG, vital 
signs, and physical examination, refer to Sections 5.2.1 to 5.2.4.
6.2.2
Treatment periods
Each subject is expected to participate in 3 treatment periods (part 1, optional part 2) or in 2 
treatment periods (optional part 3) (Days -1, 1, 2, 3, and 4 in each period). At least 14 days
will separate drug administrations in each treatment periods.
In the evening before drug administration, study participants will be admitted to the trial site 
and kept under close medical surveillance for at least 72 h following drug administration in 
the morning of Day 1. The subjects will then be allowed to leave the trial site after formal

assessment and confirmation of their fitness. No ambulatory appointments are planned during 
treatment periods.
For details on time points and procedures for collection of plasma samples for PK analysis, 
refer to Flow Chart and Section 5.3.2.
The safety measurements performed during the treatment period are specified in Section 5.2
of this protocol and in the Flow Chart. For details on times of all other trial procedures, refer 
to the Flow Chart. AEs and concomitant therapy will be assessed continuously from 
screening until the end of trial examination.
6.2.3
Follow-up period and trial completion
For AE assessment, laboratory tests, recording of ECG and vital signs, and physical 
examination during the follow-up period, see Sections 5.2.1 to 5.2.6.
Subjects who discontinue treatment before the end of the planned treatment period should 
undergo the EoT Visit.
All abnormal values (including laboratory parameters) that are assessed as clinically relevant 
by the investigator will be monitored using the appropriate tests until a return to a medically 
acceptable level is achieved. (S)AEs persisting after a subject’s EoT Visit must be followed 
until they have resolved, have been sufficiently characterised, or no further information can 
be obtained.
For definition of ‘end of the trial’ refer to Section 8.6.

STATISTICAL METHODS AND DETERMINATION OF
SAMPLE SIZE
7.1
STATISTICAL DESIGN – MODEL
The main objective of this trial is to investigate the relative bioavailability of several MR 
formulations of Nintedanib (Test, T) compared to 
mg of Ofev® IR, twice daily 
(Reference, R) following oral administration on the basis of the primary and secondary 
pharmacokinetic endpoints, as listed in Section 2.1.2 and 2.1.3. The trial is designed to allow 
intra-subject comparisons and will be evaluated statistically by use of a linear model for 
logarithmically transformed PK endpoints.
A further objective is to evaluate and compare further pharmacokinetic parameters between 
the treatments. These pharmacokinetic parameters will be assessed by descriptive statistics.
The assessment of safety and tolerability is a further objective of this trial, and will be 
evaluated by descriptive statistics for the parameters specified in Section 2.2.2.2.
7.2
NULL AND ALTERNATIVE HYPOTHESES
The relative bioavailability of each of the MR formulations compared with 
mg of Ofev®
IR will be estimated by the ratios of the geometric means (test/reference), and their 
corresponding 2-sided 90% confidence intervals (CIs) will be provided. This method 
corresponds to the two one-sided t-test procedure, each at the 5% significance level. Since the 
main focus is on estimation and not testing, a formal hypothesis test and associated 
acceptance range is not specified.
7.3
PLANNED ANALYSES
Analysis sets
Statistical analyses for each crossover part will be based on the following analysis sets:
∀
Treated set (TS): The treated set includes all subjects who were randomised and 
treated with at least one dose of study drug. The treated set will be used for safety 
analyses.
∀Pharmacokinetic parameter analysis set (PKS): This set includes all subjects in the 
treated set (TS) who provide at least one PK endpoint that was defined as primary or 
secondary and was not excluded due to a protocol deviation relevant to the evaluation 
of PK or due to PK non-evaluability (as specified in the following subsection 
‘Pharmacokinetics’). Thus, a subject will be included in the PKS, even if he/she 
contributes only one PK parameter value for one period to the statistical assessment.
Descriptive and model based analyses of PK parameters will be based on the PKS.
Adherence to the protocol will be assessed by the trial team. Important protocol deviation 
(IPD) categories will be suggested in the DV domain sheet, IPDs will be identified no later 
than in the Report Planning Meeting, and the IPD categories will be updated as needed.

Pharmacokinetics
Plasma concentration data and parameters of a subject will be included in the statistical 
pharmacokinetic (PK) analyses if they are not flagged for exclusion due to a protocol 
deviation relevant to the evaluation of PK (to be decided no later than in Report Planning 
Meeting) or due to PK non-evaluability (as revealed during data analysis, based on the 
criteria specified below). Exclusion of a subject’s data will be documented in the CTR.
Relevant protocol violations may be
∀
Incorrect trial medication taken, i.e. the subject received at least one dose of trial
medication the subject was not assigned to
∀
Incorrect dose of trial medication taken
∀
Use of restricted medications
Plasma concentrations and/or parameters of a subject will be considered as non-evaluable, if 
for example
∀
The subject experiences emesis at any time during the labelled dosing interval. 
∀
A predose concentration is >5% Cmax value of that subject
∀
Missing samples/concentration data at important phases of PK disposition curve
Plasma concentration data and parameters of a subject which is flagged for exclusion will be 
reported with its individual values but will not be included in the statistical analyses. 
Descriptive and inferential statistics of PK parameters will be based on the PKS.
Only concentration values within the validated concentration range and actual sampling times 
will be used for the calculation of pharmacokinetic parameters. Concentrations used in the 
pharmacokinetic calculations will be in the same format provided in the bioanalytical report, 
(that is, to the same number of decimal places provided in the bioanalytical report).
7.3.1
Primary endpoint analyses
Each of the crossover parts will be analysed separately according to bellows description.
Primary analyses
The statistical model used for the analysis of the primary endpoint will be an analysis of 
variance (ANOVA) model on the logarithmic scale. That is, the PK endpoints will be log-
transformed (natural logarithm) prior to fitting the ANOVA model. This model will include 
effects accounting for the following sources of variation: sequence, subjects within 
sequences, period and treatment. The effect 'subjects within sequences' will be considered as 
random, whereas the other effects will be considered as fixed. The model is described by the 
following equation:
yijkm = ∃+ %i + sim + &j + ∋k + eijkm, where
yijkm = logarithm of response measured on subject m in sequence i receiving treatment 
k in period j,

variables.
Point estimates for the ratios of the geometric means (test/reference) for the primary endpoint
(see Section 2.1) and their two-sided 90% confidence intervals (CIs) will be provided.
For each endpoint, the difference between the expected means for log(T)-log(R) will be 
estimated by the difference in the corresponding adjusted means (Least Squares Means). 
Additionally their two-sided 90% confidence intervals will be calculated based on the 
residual error from the ANOVA and quantiles from the t-distribution. These quantities will 
then be back-transformed to the original scale to provide the point estimate and 90% CIs for 
each endpoint.
Further exploratory analyses
The same statistical model as stated above will be repeated for the primary endpoint but with 
all sources of variation (‘sequence’, ‘subjects within sequences’, ‘period’, ‘treatment’) 
considered as fixed effects.
In addition to the model based approach all parameters will be calculated and analysed 
descriptively.
7.3.2
Secondary endpoint analyses
The secondary endpoints (refer to Section 2.1.3) will be calculated according to the relevant 
internal BI procedures and will be assessed statistically using the same methods as described 
for the primary endpoint.

7.3.4
Safety analyses
Safety will be analysed based on the assessments described in Section 2.2.2.2. All treated 
subjects (TS, refer to Section 7.2) will be included in the safety analysis. Safety analyses will 
be descriptive in nature and based on BI standards. No hypothesis testing is planned.
For all analyses, the treatment actually administered (= treatment at onset) to the subject will 
be used (any deviations from the randomised treatment will be discussed in the minutes of the 
Blinded Report Planning Meeting).
Treatments will be compared in a descriptive way. Tabulations of frequencies/proportions 
will be used to evaluate categorical (qualitative) data, and tabulations of descriptive statistics 
will be used to analyse continuous (quantitative) data.
Measurements (such as ECG, vital signs, or laboratory parameters) or AEs will be assigned to 
treatments (see Section 4.1) based on the actual treatment at the planned time of the 
measurement or on the recorded time of AE onset (concept of treatment emergent AEs).
Therefore, measurements planned or AEs recorded prior to first intake of trial medication will 
be assigned to the screening period, those between first trial medication intake and end of 
REP (see Section 1.2.3) will be assigned to the treatment period. Events occurring after the 
REP but prior to next intake or end of trial termination date will be assigned to ’follow-up’. 
In case of two or more treatments, the follow-up will be summarized according to the 
previous treatment. These assignments including the corresponding time intervals will be 
defined in detail in the TSAP. Note that AEs occurring after the last per protocol contact but 
entered before final database lock will be reported to Pharmacovigilance only and will not be 
captured in the trial database.
Additionally, further treatment intervals (analysing treatments) may be defined in the TSAP 
in order to provide summary statistics for time intervals, such as combined treatments, on-
treatment totals, or periods without treatment effects (such as screening and follow-up 
intervals).
Adverse events will be coded using the Medical Dictionary for Regulatory Activities 
(MedDRA). Frequency, severity, and causal relationship of AEs will be tabulated by 
treatment, system organ class, and preferred term. SAEs, AESIs (see Section 5.2.6.1), and 
other significant AEs (according to ICH E3) will be listed separately.
Previous and concomitant therapies will be presented per treatment group without 
consideration of time intervals and treatment periods.
Laboratory data will be compared to their reference ranges. Values outside the reference 
range as well as values defined as possibly clinically significant will be highlighted in the 
listings. Additionally, differences from baseline will be evaluated.
Vital signs or other safety-relevant data will be assessed with regard to possible on-treatment 
changes from baseline.
Relevant ECG findings will be reported as AEs.

7.4
INTERIM ANALYSES
Prior to start of a next study part (Part II or III) a preliminary analysis on PK parameters 
(AUC0-∞, C24 and Cmax) will be performed as described in Section 3.1.
The pharmacokinetic parameters AUC0-∞, Cmax and C24 for Nintedanib will be calculated 
according to relevant internal procedures. The non-compartmental analysis will be performed 
using a validated software program such as Phoenix WinNonlinTM software (version 6.3 or 
higher, 
 or SAS® Version 9.4 (or later version). A 
quality check of the preliminary data will be performed.
In contrast to the final PK calculations, the preliminary analysis will be based on planned 
sampling times rather than on actual times, regardless of whether actual times were within the 
time windows. Therefore, minor deviations may occur between preliminary and final results. 
The preliminary analysis will provide individual and mean concentration/effect-time profiles 
and summary statistics of individual values. The preliminary results will be distributed to the 
investigator and the trial team. 
Depending on the results of available preliminary PK analyses and the tolerability and safety 
of the compound, changes to the formulation and additional PK preliminary analysis may be 
performed if requested by the Clinical Trial Leader, the investigator, Trial Statistician or Trial 
Clinical Pharmacokineticist. Preliminary PK results will not be reported in the CTR.
7.5
HANDLING OF MISSING DATA
7.5.1
Safety
It is not planned to impute missing values for safety parameters.
7.5.2
Pharmacokinetics
Handling of missing PK data will be performed according to the relevant internal procedures.
PK parameters that cannot be reasonably calculated based on the available drug 
concentration-time data will not be imputed.
7.6
RANDOMISATION
For each of the three-way crossover part subjects will be randomised to one of the 3 treatment 
sequences in a 1:1:1 ratio. Within the two-way crossover part, subjects will be randomised to 
one of the 2 treatment sequences in a 1:1 ratio. The block size will be documented in the 
CTR.
The sponsor will arrange for the randomisation. The randomisation list will be generated 
using a validated system that uses a pseudo-random number generator and a supplied seed 
number so that the resulting allocation is both reproducible and non-predictable.
The randomisation list will contain additional blocks to allow for subject replacement (refer 
to Section 3.3.5).

The terms and conditions of the insurance coverage are made available to the investigator and 
the subjects, and are stored in the ISF.
8.1
TRIAL APPROVAL, SUBJECT INFORMATION, INFORMED CONSENT
This trial will be initiated only after all required legal documentation has been reviewed and 
approved by the respective Independent Ethics Committee (IEC) and competent authority 
(CA) according to national and international regulations. The same applies for the 
implementation of changes introduced by substantial amendments.
Prior to a subject’s participation in the trial, written informed consent must be obtained from 
each subject (or the subject’s legally accepted representative) according to ICH-GCP and to 
the regulatory and legal requirements of the participating country. Each signature must be 
personally dated by each signatory and the informed consent and any additional subject-
information form retained by the investigator as part of the trial records. A signed copy of the 
informed consent and any additional subject information must be given to each subject or the 
subject’s legally accepted representative.
The subject must be given sufficient time to consider participation in the trial. The 
investigator or delegate obtains written consent of the subject’s own free will with the 
informed consent form after confirming that the subject understands the contents. The 
investigator or 
 delegate must sign (or place a seal on) and date the informed consent form. 
If a trial collaborator has given a supplementary explanation, the trial collaborator also signs 
(or places a seal on) and dates the informed consent.

The consent and re-consenting process should be properly documented in the source 
documentation.
8.2
DATA QUALITY ASSURANCE
A risk-based approach is used for trial quality management. It is initiated by the assessment 
of critical data and processes for trial subject protection and reliability of the results as well as 
identification and assessment of associated risks. An Integrated Quality and Risk 
Management Plan documents the rationale and strategies for risk management during trial 
conduct including monitoring approaches, vendor management and other processes focusing 
on areas of greatest risk.
Continuous risk review and assessment may lead to adjustments in trial conduct, trial design 
or monitoring approaches.
A quality assurance audit/inspection of this trial may be conducted by the sponsor, sponsor’s 
designees, or by IRB / IEC or by regulatory authorities. The quality assurance auditor will 
have access to all medical records, the investigator’s trial-related files and correspondence, 
and the informed consent documentation of this clinical trial.
8.3
RECORDS
CRFs for individual subjects will be provided by the sponsor. For drug accountability, refer 
to Section 4.1.8.
8.3.1
Source documents
In accordance with regulatory requirements, the investigator should prepare and maintain 
adequate and accurate source documents and trial records for each trial subject that include 
all observations and other data pertinent to the investigation. Source data as well as reported 
data should follow the ‘ALCOA principles’ and be attributable, legible, contemporaneous, 
original, and accurate. Changes to the data should be traceable (audit trail).
Data reported on the CRF must be consistent with the source data or the discrepancies must 
be explained.
Before providing any copy of subjects’ source documents to the sponsor, the investigator 
must ensure that all subject identifiers (e.g., subject’s name, initials, address, phone number, 
and social security number) have properly been removed or redacted to ensure subject 
confidentiality.
If the subject is not compliant with the protocol, any corrective action (e.g. re-training) must 
be documented in the subject file.
For the CRF, data must be derived from source documents, for example:
∀
Subject identification: sex, year of birth (in accordance with local laws and 
regulations)
∀
Subject participation in the trial (substance, trial number, subject number, date subject 
was informed)
∀
Dates of subject’s visits, including dispensing of trial medication
