mode of admin.
Oral with 240 mL of water after an overnight fast of at least 10 h (treatment 
“Reference” (R)) or after a high-fat, high-calorie breakfast (treatment “Test” (T))
Duration of treatment
One day (single dose) for each treatment
Statistical methods
Relative bioavailability will be estimated by the ratios of the geometric means 
(test/reference) for the primary and secondary 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, subjects 
nested within sequences, period and treatment. CIs will be calculated based on the 
residual error from the ANOVA.
Descriptive statistics will be calculated for all endpoints.

INTRODUCTION
BI 894416 is an oral, selective non-receptor protein tyrosine kinase SYK (spleen tyrosine 
kinase) inhibitor under clinical development for the indication of uncontrolled severe asthma.
This trial will be performed to investigate the relative bioavailability of BI 894416 in plasma 
when given after a high-fat, high-calorie breakfast in comparison to when given in the fasting 
state.
1.1
MEDICAL BACKGROUND
Asthma is a heterogenous disease characterized by a chronic inflammatory process of the 
airways and driven by both the innate and adaptive immune pathways [R14-4230, P08-
01263]. In severe asthma, the T type 2 inflammation (T2) -high and T2-low, and the non-T2 
pathways are involved associated with a mixed pattern of inflammation involving eosinophil, 
basophil, mast, neutrophil, innate lymphoid and dendritic cells [R15-5888, R16-0945].
SYK is a non-receptor cytoplasmic tyrosine kinase that is predominantly expressed in cells of 
hematopoietic lineage, including B cells, T cells, monocytes, NK cells, mast cells, basophils, 
and neutrophils [R15-5470]. SYK is a key component of the signal transduction associated 
with the T2-high and T2-low, and non-T2 asthma pathways that is activated through 
interaction with allergens and a number of innate and adaptive immune receptors including 
Fc receptors on basophils, mast, B- and T cells. SYK is essential for the FcεR1-mediated 
activation and degranulation of mast cells and basophils. SYK is also important in the signal 
propagation of the dectin family of innate receptors, present on macrophages, dendritic cells 
and neutrophils. Furthermore, SYK has important roles in B-cell and T-cell development, 
with partially redundant functions with Zeta-chain-associated protein kinase of 70 kDa 
(ZAP70) [R15-5470, R16-5298].
For more details on medical background see the current version of the Investigator’s 
Brochure (IB) [c03536505].
1.2
DRUG PROFILE
BI 894416 is a potent and selective inhibitor of SYK. Based on pre-clinical in vitro and in 
vivo data, SYK inhibition is expected to have effect on the non-T2 and T2 inflammatory 
pathway components of severe asthma.
So far, BI 894416 was investigated in one clinical phase I first-in-man trial (BI study number 
1371-0001) in healthy male volunteers. Trial 1371-0001 consisted of two trial parts, a single-
rising dose (SRD) part and a relative bioavailability part. Single-dose treatment with up to 70 
mg BI 894416 or placebo as oral solution in the SRD part of trial 1371-0001 as well as 
administration of three single doses (10, 10, and 40 mg BI 894416) as tablet or oral solution 
in the relative bioavailability part was safe and well tolerated. 
For details on preliminary safety and tolerability as well as on pharmacokinetics and 
biomarker data of trial 1371-0001 refer to the IB [c03536505].

The Residual Effect Period (REP, i.e., the period after the last dose with measurable drug 
levels and/or pharmacodynamic effects still likely to be present) of BI 894416 has not been 
defined yet. However, the elimination half-life of BI 894416 is short (gMean apparent 
terminal half-life between 3.0 and 5.8 h in the SRD part of trial 1371-0001), the mode of 
action is reversible, and safety and tolerability in trial 1371-0001 were good. This suggests 
that the occurrence of any potential adverse effects would likely be limited to a low number 
of days. 
The End-of-Trial visit is earliest on Day 8 following BI 894416 dosing in period 2. This is 
expected to cover the period during which any adverse effects could reasonably occur. 
1.3
RATIONALE FOR PERFORMING THE TRIAL
So far, BI 894416 has been administered to humans in the fasting state, only. In future trials, 
e.g., in multiple-dosing trials in patients, BI 894416 will be administered also in the non-
fasting state. However, so far it has not been investigated whether oral bioavailability of 
BI 894416 could be affected by food. 
This clinical trial will be performed to investigate the effect of food on bioavailability 
(assessed as relative bioavailability comparison of fed vs. fasting state) of BI 894416 as tablet 
formulation.
1.4
BENEFIT - RISK ASSESSMENT
Participation in this clinical trial is without any (therapeutic) benefit for healthy subjects. 
Their participation, however, is of major importance for the development of BI 894416. 
Subjects are exposed to risks of study procedures and risks related to the exposure to the trial 
medication.
1.4.1
Expected benefit to the target population
Asthma is a heterogeneous disease that is driven by the innate and adaptive immune pathway.
In severe asthma, both the T2-high and T2-low, and the non-T2 inflammation pathways are 
involved, and associated with a mixed pattern of inflammation involving eosinophil, 
basophil, mast, neutrophil, innate lymphoid and dendritic cells. Up to 50% of severe asthma 
is driven by the non T2 and/or T2-low alone or in combination with the T2-high pathway. 
This non T2 / T2-low component represents an area of unmet medical need that does not 
respond to high dose inhaled corticosteroids or other current controller therapy, and is 
unlikely to respond to the T2-high monoclonal antibodies targeted therapies. 
SYK is a key component of signal transduction associated with the T2-high and T2-low, and
non-T2 asthma pathways that is activated through interaction with allergens and a number of
innate and adaptive immune receptors including Fc receptors on basophils, mast, B and T

cells. SYK is also important in the signal propagation of the dectin family of innate receptors,
present on macrophages, dendritic cells and neutrophils.
Such a therapy would meet a substantial unmet need for severe asthma patients, especially
those with a non T2 and/or T2-low component, whether early/late-onset or steroid resistant,
and could become a safe and effective substitute used before high dose inhaled 
corticosteroids, oral systemic corticosteroids or T2-high biological monoclonal antibodies.
1.4.2
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.
ECG electrodes may cause local and typically transient skin reactions.
The total volume of blood withdrawn per subject during the entire study will not exceed the 
volume of a normal blood donation (500 mL). No health-related risk to healthy subjects is 
expected from withdrawal of this volume of blood.
1.4.3
Drug-related risks and safety measures
Potential effects on immune cells
SYK is involved in the function of basophil, mast, neutrophil and dendritic cells. Moreover, 
SYK is implicated in the development and function of both T cells and B cells. For details 
refer to the IB [c03536505].
The risk for healthy volunteers due to effects of BI 894416 on immune cells is expected to be 
minimal, for the following reasons:

Inhibition of SYK is not expected to have a negative effect with regards to the 
immune response of innate immune cells to viral or bacterial infections due to
redundancy in the infection immune response. The key neutrophil and dendritic cell 
functions most likely will be triggered by alternative pathways.

Safety and tolerability data of trial 1371-0001 are not suggestive of an increased risk 
of infectious adverse events or of any relevant BI 894416-related findings in WBC, 
differential blood count, immunoglobulins, or lymphocyte subpopulations after single 
doses up to 70 mg BI 894416 (see IB [c03536505]).

Due to the reversible mode of action of BI 894416 with regards to SYK inhibition, 
any potential effects on immune cells are expected to be of transient nature.
Risk mitigation and monitoring: Subjects with a history or diagnosis of relevant 
immunological disease will be excluded from trial participation (see Section 3.3.3). Adverse 
events will be monitored for an increase in infectious adverse events. Safety laboratory 
contains WBC, differential blood count, and CRP.

Tumour biology and carcinogenicity
The SYK pathway has been hypothesized to act as both a tumour suppressor and a tumour 
promoter in different types of human cancers [R16-4459]. An increased risk of 
carcinogenic/metastatic potential in epithelial cancers has been reported in the literature 
related to SYK knock-out, but not related to SYK inhibition. Allelic deletion of SYK has 
been associated with breast adenocarcinoma [R15-4770]. However, there is no evidence that 
pharmacologic inhibition of SYK will increase carcinogenicity or metastatic risk. Preclinical 
data with a potent and selective tool SYK inhibitor, BI 1002494, are in line with an absence 
of a carcinogenic effect due to inhibition of SYK enzymatic function [n00243171]. 
Risk mitigation and monitoring: Only male subjects are included in this trial. In view of the 
extended time necessary to induce a carcinogenic effect, two single doses of BI 894416 are 
not considered a relevant carcinogenic risk to male subjects participating in this study. 
Accordingly, no further risk mitigation is required in this study. 
Platelet aggregation and bleeding risk
A role of SYK in platelet function has been demonstrated in literature [R15-5470]. Several 
platelet functions rely on SYK signalling (e.g. collagen receptor GPVI) but others are 
independent of SYK [R16-5240]. In vitro studies using human platelets demonstrated that at 
concentrations up to 100 μM, BI 894416 had no effect on extrinsic or intrinsic coagulation 
pathways. Also, BI 894416 did not inhibit ADP-induced platelet aggregation up to 100 μM. 
However, BI 894416 inhibited collagen- and arachidonic acid-induced platelet aggregation at 
3 μM and 5 μM. However, platelet function as measured by bleeding time is not affected by a 
drug unless all the platelet pathways are inhibited due to redundancy within the system. 
Therefore, no risk for bleeding exists with regard to platelet inhibition unless a subject is also 
on another antiplatelet drug that blocks these other pathways. 
Risk mitigation and monitoring: Use of any other concomitant drug that could reasonably 
inhibit platelet aggregation or coagulation (e.g. acetylsalicylic acid) will be prohibited (see 
Section 4.2.2.1). Adverse events will be monitored for any signs of bleeding or bleeding-
related adverse events.
Bone density
SYK is reported to be involved in osteoclast differentiation, development and function. For 
details see the IB [c03536505]. In this trial, each subject is treated with two single doses of 
BI 894416. Due to comparatively slow turnover of bone tissue, no relevant effect on bone is 
expected due to two single-dose administrations with BI 894416 in this trial, and no specific 
monitoring of bone density is necessary or reasonable in this trial.

Genotoxicity, reproductive and developmental toxicity
Genetic toxicology results by weight of evidence indicate that BI 894416 is not mutagenic or 
clastogenic. In the 2-week repeat dose range finding study in male rats [n00240179], 
degeneration of spermatids of the testes was observed at ≥400 mg/kg/day, which is 
considered a secondary effect, related to overt toxicity and morbidity. 
It is unknown whether BI 894416 or its metabolites are distributed into male semen. 
Theoretically there is therefore a risk for exposure of a study subject’s female partner who is 
a woman of child bearing potential (WOCBP) to subtherapeutic exposures of BI 894416 or 
its metabolites via male semen. Developmental and reproductive studies have not yet been

conducted, therefore the effect of subtherapeutic concentrations of BI 894416 or its 
metabolites with regards to embryofetal risk has not been explored so far.
Risk mitigation: In order to address the risk of exposure of a subject’s female WOCBP 
partner to BI 894416 or its metabolites via the subject’s seminal fluid, subjects need to use 
barrier contraception (condom) or abstinence (see Section 3.3.3).
Phototoxicity
Subjects will be advised to avoid direct exposure to sun and UV light during the entire study 
(see Section 4.2.2.2). Further protective measures would not be necessary given the low 
phototoxic potential of BI 894416.
Potential effects on QT interval
Preclinical studies suggested no proarrhythmic potential or cardiovascular liability with 
BI 894416. However, statistical results of first-in-man trial 1371-0001 showed a most-likely 
dose- and concentration-dependent increase of QTcF interval. At gMean Cmax of the 70 mg 
dose group, placebo- and baseline-corrected predicted mean QTcF increase was 5.9 ms 
(upper limit of the 90% CI was 10.5 ms). A dose- or concentration-dependent effect on heart 
rate was not observed. It is expected that plasma concentrations reached in current trial 1371-
0021 are lower than the maximal plasma concentrations reached in trial 1371-0001.
Risk mitigation: Subjects with cardiovascular disorders (Section 3.3.3, exclusion criterion 5), 
subjects who used drugs that cause QT/QTc prolongation (Section 3.3.3, exclusion criterion 
11), subjects that show a marked baseline prolongation of QT/QTc interval or any other 
relevant ECG finding at screening (Section 3.3.3, exclusion criterion 19), and subjects with a 
history of additional risk factors for Torsade de Pointes arrhythmia (Section 3.3.3, exclusion 
criterion 20) are excluded from trial participation. Moreover, subjects are in-house under 
close observation for 24 h following drug administration, and ECGs are done pre- and post-
dose at the time points given in the Flow Chart. Considering these risk-mitigating measures, 
the risks to subjects participating at trial 1371-0021 due to potential effects on QT interval are 
considered minimal.
Drug-induced liver injury
Although rare, a potential for drug-induced liver injury (DILI) is under constant surveillance 
by sponsors and regulators. Therefore, this trial requires timely detection, evaluation, and 
follow-up of laboratory alterations in selected liver laboratory parameters to ensure subjects´ 
safety; see also section 5.2.6.1.4, adverse events of special interest.
1.4.4
Overall assessment of benefit-risk ratio
BI 894416 is a highly specific SYK inhibitor that has been adequately characterised in pre-
clinical studies. The non-clinical safety package supports administration of BI 894416 for up 
to 4 weeks duration to men.

Data of trial 1371-0001 indicate good safety and tolerability of single oral doses of 
BI 894416 at all dose levels, i.e. up to 70 mg. In addition, data from oral administration of 
three SYK inhibitors are available and provide additional information on safety and 
tolerability of this class of drug in man. Published data indicate acceptable safety and 
tolerability of these three SYK inhibitors in healthy volunteers (see IB [c03536505]).
Plasma concentrations of BI 894416 in current trial 1371-0021 are expected to be in the range 
of the plasma concentrations that were measured in previous trial 1371-0001 and that were 
associated with good safety and tolerability.
Inhibition of SYK would meet a substantial unmet need for severe asthma patients, especially 
those with a non T2 and/or T2-low component, whether early/late-onset or steroid resistant, 
and could become a safe and effective substitute used before high dose inhaled 
corticosteroids, oral systemic corticosteroids or T2-high biological monoclonal antibodies.
This trial is required for the development of BI 894416. It is designed to assess the effect of 
food on bioavailability of BI 894416 as tablet formulation (in terms of relative bioavailability 
in fed vs. fasting state). The resulting data are planned to inform future trials regarding the 
administration of BI 894416 in relation to food intake.
Considering the medical need for an effective and safe treatment of uncontrolled severe 
asthma, the benefit of this trial is assessed to outweigh the potential risks.

DESCRIPTION OF DESIGN AND TRIAL POPULATION
3.1
OVERALL TRIAL DESIGN AND PLAN
The study will be performed as a randomised, open-label, two-way crossover trial in healthy 
male subjects in order to compare the test treatment (T) to the reference treatment (R). The 
treatments will be 30 mg BI 894416 as tablet formulation (3 tablets à 10 mg) following a 
high-fat, high-calorie breakfast (T) or 30 mg BI 894416 as tablet formulation (3 tablets à 
10 mg) administered in the fasting state (R). The subjects will be randomly allocated to the 2 
treatment sequences (T-R or R-T). For details, refer to Section 4.1.
There will be a washout period of at least 5 days between the treatments.
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.
3.2
DISCUSSION OF TRIAL DESIGN, INCLUDING THE CHOICE OF 
CONTROL GROUP
For relative bioavailability trials, the crossover design is preferred because of its efficiency: 
since each subject serves as his own control, the comparison between treatments is based on 
an intra-subject comparison, thus removing inter-subject variability from the comparison 
between treatments [R94-1529].
The open-label treatment is not expected to bias results, since the study endpoints are derived 
from measurement of plasma concentrations of the analyte, which are not expected to be 
influenced by the knowledge of treatment received.
3.3
SELECTION OF TRIAL POPULATION
It is planned that 14 healthy male subjects will enter the study. They will be recruited from 
the volunteers' pool of the trial site.
Only male subjects will be included in the study because no data on reproductive toxicology 
are available at this time and because, until availability of data from the 26-week Tg.rasH2 
carcinogenicity study, study populations are restricted to male volunteers or patients (see IB 
[c03536505]).
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.
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:

discontinuation, a complete end of trial examination will be performed, if possible, and the 
information will be recorded in the CRF. 
3.3.4.1
Discontinuation of trial treatment
An individual subject will discontinue trial treatment if:
1. The subject wants to discontinue trial treatment, without the need to justify the decision
2. 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.
3. The subject needs to take concomitant medication that interferes with the investigational 
medicinal product or other trial treatment
4. The subject can no longer receive trial treatment for medical reasons (such as surgery, 
adverse events [AEs], or diseases)
5. The subject has 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
6. The subject experiences a drug-related AE of severe intensity or a serious AE.
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 or at a particular trial site
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 
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
3. Violation of GCP or the CTP impairing the appropriate conduct of the trial

The investigational product has been manufactured by BI Pharma GmbH & Co. KG.
4.1.1
Identity of the Investigational Medicinal Products
The characteristics of the test product are given below:
Substance:
BI 894416
Pharmaceutical formulation: Tablet
Source:
BI Pharma GmbH & Co. KG, Germany
Unit strength:
10 mg
Posology:
3-0-0
Route of administration:
oral
Duration of use:
1 day (in treatment R and T)
4.1.2
Selection of doses in the trial
For the current trial a dose of 30 mg BI 894416 is selected to ensure that, in case 
administration with food increases the bioavailability of BI 894416, BI 894416 plasma 
concentrations are in the range that were reached in previous first-in-man trial 1371-0001 and 
that were safe and well-tolerated.
BI 894416 is a BCS class I compound. As such, no relevant food effect is expected, however, 
until food effect results in man are available, we assume as a worst-case that an up to 2-fold 
increase of BI 894416 bioavailability when given with food cannot be fully excluded.
In first-in-man trial 1371-0001, single oral doses of 3 to 70 mg BI 894416 were given as oral 
solution, and doses of 10 and 40 mg were given as tablets. All doses in trial 1371-0001 were 
assessed as safe and well-tolerated. In trial 1371-0001, BI 894416 gMean plasma exposure at 
a dose of 30 mg was 527 nM for Cmax and 3140 nM*h for AUC0-24, and BI 894416 gMean 
plasma exposure at a dose of 70 mg was 2190 nM for Cmax and 11200 nM*h for AUC0-24
(preliminary data, see c03536505). That means, the ratios of gMean plasma exposure 
parameters at 70 mg and at 30 mg were approximately 4 for both Cmax and AUC0-24. These 
ratios are sufficient for the current trial to cover potential BI 894416 plasma exposure 
increases when given with food.
4.1.3
Method of assigning subjects to treatment groups
The randomisation list will be provided to the trial site in advance.
Subjects will be allocated to treatment sequences prior to the first administration of trial 
medication in the morning of Day 1 (Visit 2). For this purpose, numbers of the randomisation

list will be allocated to the subjects by drawing lots. Subjects are then assigned to a treatment 
sequence according to the randomisation list.
Once a subject number has been assigned, it cannot be reassigned to any other subject.
The randomisation procedure is described in Section 7.6.
All subjects may be treated in one cohort, i.e. all subjects may receive treatment on the same 
calendar day. In case this is not feasible (e.g., due to logistical or recruitment reasons), the 
group may be split into several cohorts as required. Treatment of all subjects on the same 
calendar day is acceptable from a safety point of view (for safety margin to exposure in 
previous SRD trial 1371-0001 refer to Section 4.1.2; for discussion of study-associated risks 
and safety measures see Section 1.4).
4.1.4
Drug assignment and administration of doses for each subject
This trial is a 2-way crossover study. All subjects will receive the 2 treatments in randomised 
order. The treatments to be evaluated are outlined in Table 4.1.4: 1 below.

Administration of investigational medicinal product: The investigator (or authorised 
designee) will administer the trial medication as an oral dose together with about 240 mL of 
water to subjects who are in a sitting/standing position. For drug administration, the so-called 
four-eye principle (two-person rule) should be applied. For this, one authorised employee of 
the trial site should witness the administration of trial medication, and – if applicable – its 
preparation (e.g. reconstitution), if correct dosage cannot be ensured otherwise.
Treatment R: Administration of trial medication will be performed after subjects have fasted 
overnight; fasting is to start no later than 10 h before the scheduled dosing. 
Treatment T: Subjects are  to fast overnight prior to administration. Fasting is to start no later 
than 10 h before the scheduled dosing. A high-fat, high-calorie meal will be served 30 min
before drug administration. The subjects must completely consume the meal prior to drug 
intake. The composition of the standard high-fat, high-calorie meal is detailed in Table 
4.1.4: 2; this meal is in compliance with the FDA guidance ‘Food-Effect Bioavailability and 
Fed Bioequivalence Studies’ [R03-2269]. For restrictions with regard to diet, see Section 
4.2.2.2.

The total caloric content is supplied approximately as following: 150 kcal as protein, 250 kcal as 
carbohydrate, and 500 to 600 kcal as fat. 
All treatments: Subjects will be kept under close medical surveillance until 24 h after drug 
administration. During the first 4 h after drug administration, subjects are not allowed to lie 
down (i.e. no declination of the upper body of more than 45 degrees from upright posture).
The treatments will be separated by a wash-out phase of at least 5 days.
4.1.5
Blinding and procedures for unblinding
This open label Phase I trial will be handled in an open fashion throughout (that is, during the 
conduct, including data cleaning and preparation of the analysis). This is considered
acceptable because the potential for bias seems to be low and does not outweigh practical 
considerations.
Emergency envelopes will not be provided, because the dose of trial medication and food 
condition is known to investigators and subjects.
4.1.6
Packaging, labelling, and re-supply
The investigational medicinal products will be provided by BI. They will be packaged and 
labelled in accordance with local law and the principles of Good Manufacturing Practice. 
For details of packing and the description of the label, refer to the ISF.
The telephone number of the sponsor and the name, address and telephone number of the trial 
site are provided in the subject information form. The EudraCT number is indicated on the 
title page of this protocol as well as on the subject information and informed consent forms. 
No re-supply is planned.
4.1.7

Twelve-lead ECGs (I, II, III, aVR, aVL, aVF, V1 - V6) will be recorded using a 
computerised electrocardiograph (CardioSoft EKG System, GE Medical Systems, Freiburg, 
Germany) 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 ECGs will be stored electronically on the Muse CV Cardiology System (GE Medical 
Systems, Freiburg, Germany). Electrode placement will be performed according to the 
method of Wilson, Goldberger and Einthoven modified by Mason and Likar (hips and 
shoulders instead of ankles and wrists). 
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. 
5.2.5
Other safety parameters
5.2.5.1
Neurological examination
At Screening, a physical neurological examination will be performed. Upon investigator 
judgment, additional neurological examinations may be added at any time during the trial, for 
individual subjects or for the whole treatment group.
The neurological examination will include the following assessments:
-
Eye movement
-
Pupil size and pupil reactivity
-
Reflexes 
-
Assessment of muscle strength
-
Gait
-
Romberg test
-
Tremor
-
Point-to-point movements
-
Sensitivity
Documentation, Assessment, and Reporting
Results will be documented in source data at the clinical trial site and assessed for clinical 
relevance by an investigator, deputy investigator or sub-investigator. Clinically relevant 
findings of the neurological examination will be reported as Adverse Events (during the trial) 
or as baseline conditions (at screening). Case narratives may be written if necessary.

5.2.6
Assessment of adverse events
5.2.6.1
Definitions of adverse events
Adverse event
5.2.6.1.1
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.
Serious adverse event
5.2.6.1.2
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
AEs considered ‘Always Serious’
5.2.6.1.3
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 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.
The latest list of ‘Always Serious AEs’ can be found in the eDC system, an electronic data 
capture system which allows the entry of trial data at the trial site. These events should 
always be reported as SAEs as described above.
Adverse events of special interest
5.2.6.1.4
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

Intensity (severity) of AEs
5.2.6.1.5
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
Causal relationship of AEs
5.2.6.1.6
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)

Disappearance of the event even though the trial drug treatment continues or remains 
unchanged

5.2.6.2
Adverse event collection and reporting
AE collection
5.2.6.2.1
Upon enrolment into a trial, 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) and all AESIs 
o
The only exception to this rule are AEs (serious and non-serious) and AESIs 
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 and related 
AESIs 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.

AE reporting to the sponsor and timelines
5.2.6.2.2
The Investigator must report SAEs, AESIs, and non-serious AEs which are relevant for the 
reported SAE or AESI, on the BI SAE form via fax immediately (within 24 hours) to the 
sponsor’s unique entry point (country specific contact details will be provided in the ISF). 
The same timeline applies if follow-up information becomes available. In specific occasions 
the Investigator could inform the sponsor upfront via telephone. This does not replace the 
requirement to complete and fax the BI SAE form. 
With receipt of any further information to these events, a follow-up SAE form has to be 
provided. For follow-up information, the same rules and timeline apply as for initial 
information.
Information required
5.2.6.2.3
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 
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 BI 894416 concentrations in plasma, 2.7 mL of blood will be drawn 
from an antecubital or forearm vein into a 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 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 within 90 min, with interim storage of blood samples and aliquots at room 
temperature. 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. Further information such as matrix may also be provided.
After completion of the quantification of BI 894416 in a plasma aliquot, the left-over and/or
back-up aliquot 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.
5.3.3
Analytical determinations
5.3.3.1
Analytical determination of analyte plasma concentration
BI 894416 concentrations in plasma will be determined by a validated LC-MS/MS (liquid 
chromatography tandem mass spectrometry) assay. All details of the analytical method will 
be available prior to the start of sample analysis. 
5.4
BIOBANKING
Not applicable.
5.5
OTHER ASSESSMENTS
5.5.1
Pharmacogenomic evaluation
Pharmacogenomic investigations explore the role of genetic variation in determining an 
individual’s response to drugs. For this purpose, a sample of at most 10 mL of blood will be 
obtained at the screening examination from each subject whose genotype has not been 
previously determined. Separate informed consent for genotyping will be obtained from each 
volunteer prior to sampling.
DNA will be extracted from the blood sample in order to sequence genes coding for proteins 
that are involved in the absorption, distribution, metabolism, and excretion (ADME) of drugs. 
The gene sequences to be determined include known and likely functional variations of key 
ADME genes and incorporate more than 90% of ADME-related genetic markers identified by 
the PharmaADME group (weblink.pharmaadme.org). It is not intended to include the 
pharmacogenomic data in the CTR. However, the data may be part of the CTR, if necessary.
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 Sections 2.1.2, 
2.1.3, 2.2.2.1, and 5.3 are generally used assessments of drug exposure.

Due to neurologic effects observed in dog studies, a neurological examination is performed at 
Screening to ensure that no subject with a clinically relevant finding in the neurological 
examination is included into the trial. Upon investigator judgment, additional neurological 
examinations may be added at any time during the trial, for individual subjects or for the 
whole treatment group.

INVESTIGATIONAL PLAN
6.1
VISIT SCHEDULE
Exact times of measurements outside the permitted time windows will be documented. The 
acceptable time windows for screening and the end of trial examination are provided in the 
Flow Chart.
Study measurements and assessments scheduled to occur ‘before’ trial medication 
administration on Day 1 are to be performed and completed within a 3 h-period prior to the 
trial drug administration.
The acceptable deviation from the scheduled time for vital signs, ECG, and laboratory tests 
will be ± 1 h.
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.
Starting from 48 hours after BI 894416 administration a time window of ± 120 min will be 
allowed for all study activities.  
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, physical examination and neurological examination, refer to Sections 5.2.1 to 5.2.5.
Genotyping will be performed in those volunteers whose genotypes have not been previously 
determined (for details, see Section 5.5.1).
6.2.2
Treatment periods
Each subject is expected to participate in 2 treatment periods (Days -5 to 3 in period 1 and 
Days 1, 2, and 3 in period 2). At least 5 days will separate drug administrations in the first 
and second treatment periods.

On Day 1 of each treatment period, study participants will be admitted to the trial site and 
kept under close medical surveillance for at least 24 h following drug administration. The 
subjects will then be allowed to leave the trial site after formal assessment and confirmation 
of their fitness. On all other study days, subjects will be treated in an ambulatory fashion.
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, physical examination 
and neurological 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 EoTrial 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 EoTrial Visit must be 
followed until they have resolved, have been sufficiently characterised, or no further 
information can be obtained.

STATISTICAL METHODS AND DETERMINATION OF 
SAMPLE SIZE
7.1
STATISTICAL DESIGN – MODEL
The main objective of this trial is to investigate the effect of food on the relative 
bioavailability of BI 894416 administered as a single dose of 30 mg to healthy male 
volunteers. The drug administration after a standardised high fat, high caloric meal is 
regarded as the test treatment (T) while the intake of BI 894416 tablets under fasted 
conditions is the reference treatment (R). The trial is designed to allow intra-subject
comparisons between the fasted and fed condition and will be evaluated statistically by use of
an appropriate linear model.
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 BI 894416 formula tablet (30 mg) under fasted conditions (R) 
compared to BI 894416 formula tablets (30 mg) under fed conditions (T) will be estimated by 
the ratios of the geometric means (test/reference) for the primary and secondary PK 
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 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 will be based on the following analysis sets:

Treated set (TS): The treated set includes all subjects who were 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 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 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 Integrated Quality and Risk Management Plan

(IQRMP), IPDs will be identified no later than in the Report Planning Meeting, and the IPD
categories will be updated as needed.
Pharmacokinetics
The pharmacokinetic parameters listed in Section 2.1 for drug BI 894416 will be calculated 
according to the relevant SOP of the Sponsor (001-MCS-36-472). 
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 the 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 deviations 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 experienced emesis at or before two times median tmax. Median tmax is to 
be taken either from the median tmax for the reference treatment or from median tmax
for the test treatment, depending on whether the subject had experienced emesis after 
taken the test or the reference treatment. Median tmax is to be determined excluding the 
subjects experiencing emesis.

A predose concentration of BI 894416 is >5% Cmax value of that subject in the 
respective treatment period

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
Statistical model
The statistical model used for the analysis of the primary (AUC0-tz and Cmax) and secondary 
(AUC0-∞) endpoints will be an analysis of variance (ANOVA) model on the logarithmic 
scale. This model will include effects accounting for 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. For tests 
on subject, period, and treatment effects, the denominator sum of squares will be the sum of 
squares for error; while for tests on sequence effects, the denominator will be the sum of 
squares for subjects. The model is described by the following equation:
yijkm = + i + sim + j + k + eijkm, where
yijkm = logarithm of response (AUC0-tz , Cmax and AUC0-∞) measured on subject m in 
sequence i receiving treatmentk in period j,
= the overall mean,
i = the ith sequence effect, i = 1, 2,
sim = the effect associated with the mth subject in the ith sequence,
m = 1, 2, ..., ni
j = the jth period effect, j = 1, 2,
k = the kth treatment effect, k = 1, 2,
eijkm = the random error associated with the mth subject in sequence i who received
treatment k in period j.
where s ~ N(0, σ
) i.i.d., e ~ N(0, σ
 ) i.i.d. and sim, eijkm are independent random 
variables.
Primary analysis
Point estimates of bioavailability, the ratios of the geometric means (test/reference) for the 
primary endpoints (see 2.1.2), and their two-sided 90% confidence intervals (CIs) will be 
provided.
The pharmacokinetic parameters (AUC0-tz and Cmax) will then be log transformed (natural
logarithm) prior to fitting the ANOVA model. The difference between the expected means
for test treatments and reference treatment log(T)-log(R), will be estimated by the difference
in the corresponding Least Square Means (point estimate) and two-sided 90% confidence
intervals based on the t-distribution will be computed. These quantities will then be back
transformed to the original scale to give the point estimator (geometric mean) and interval
estimates for the ratio between response under test/ fed condition and response under
reference/ fasted condition.

Pharmacokinetic parameters of a subject will be included in the analysis unless the subject
has an important protocol deviation relevant for the evaluation. If an important protocol
deviation only affects one treatment period the analysis for the other period from this subject
is included anyway. Whether a protocol deviation is important will be decided no later than in
the Report Planning Meeting.
7.3.2
Secondary endpoint analyses
The secondary endpoints (refer to Section 2.1.3) will be calculated according to the BI SOP 
‘Standards and processes for analyses performed within Clinical Pharmacokinetics/ 
Pharmacodynamics’ (001-MCS-36-472) and will be assessed statistically using the same 
methods as described for the primary endpoints.
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 
Report Planning Meeting).
Treatments under fed and under fasted condition 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 and those between trial medication intake and the trial
medication intake in the next treatment period or the EoTrial Visit (whatever comes next) 
will be assigned to the respective treatment. 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
A preliminary, exploratory analysis of the PK parameters (AUC0-tz, AUC0-∞and Cmax of 
BI 894416) may be performed based on all evaluable data after last subject out and prior to 
data base lock. This may be necessary, e. g., in case the information is needed to inform other 
activities during the development of BI 894416 such as food intake in relation to BI 894416 
intake in other studies. In contrast to the final PK calculations, the preliminary, exploratory
analysis will be based on planned sampling times rather than on actual times, regardless of 
whether actual times were within the time windows or not. Therefore, minor deviations of 
preliminary and final results may occur. Results will be provided as individual values and 
geometric means as well as the adjusted gMean ratios determined according to the planned 
primary analysis described in Section 7.3.1. The preliminary, exploratory results will be 
distributed to the trial team.

concentration-time data will not be imputed.
7.6
RANDOMISATION
Subjects will be randomised to one of the two treatment sequences (RT or TR) in a 1:1 ratio.
The block size will be documented in the CTR.
The sponsor will arrange for the randomisation as well as packaging and labelling of trial 
medication. 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).
7.7
DETERMINATION OF SAMPLE SIZE
It is planned to enter a total of 14 subjects in the trial, including up to 2 non PK evaluable 
subjects. The planned sample size is not based on a power calculation but is considered 
sufficient to achieve the aims of this exploratory trial. With this sample size, the following 
precision in estimating the ratio of geometric means (test/reference) can be expected with 
95% probability. Precision is defined as the ratio of upper CI limit to the relative BA 
estimate. Note that the precision is independent of the actual ratio of geometric means.
The intra-individual coefficient of variation (gCV) was estimated from inter-individual gCV 
from preliminary PK data of the SRD part of a previous trial using the 30 mg dose (data on 
file) which will also be used in this trial. The observed inter-individual gCV was roughly 
31% for Cmax and 26% for AUC0-tz. Assuming a within-subject correlation of 0.6 for Cmax and 
0.8 for AUC0-tz, the estimated upper 70% CI of the intra-individual gCV was roughly 27% for 
Cmax and 15% for AUC0-tz..
Assuming a gCV of 15% for BI 894416 and given a sample size of 12 subjects with 
evaluable data for primary analysis, the precision of the two-sided 90% confidence interval of 
the bioavailability ratio will be approximately 1.16 for a greater gCV of 27%, the precision 
would still be approximately 1.30. Table 7.7: 1 provides an overview of the achievable 
precision for estimating the ratio of geometric means (test/reference). For illustrative 
purposes, the expected 90% confidence intervals with 95% tolerance probability are 
displayed for different values of the ratios T/R of geometric means.

*Ratio of geometric means (test/reference) for a PK endpoint is defined by exp(T)/exp(R).
The expected 90% confidence interval limits in the table were derived by
CI limit,  = exp(ln(θ) ± ω),
with θ being the ratio (T/R) on original scale and ω the distance from the estimate θ to either 
confidence interval limit on the log-scale, which was obtained from the achievable precision 
on the original scale.
The calculation was performed as described by Julious [R11-5230] using R Version 3.5.1.

INFORMED CONSENT, TRIAL RECORDS, DATA 
PROTECTION, PUBLICATION POLICY, AND 
ADMINISTRATIVE STRUCTURE
The trial will be carried out in compliance with the protocol, the ethical principles laid down 
in the Declaration of Helsinki, in accordance with the ICH Harmonized Guideline for Good 
Clinical Practice (GCP), relevant BI Standard Operating Procedures (SOPs), the EU 
regulation 536/2014, and other relevant regulations. Investigators and site staff must adhere 
to these principles.
Standard medical care (prophylactic, diagnostic, and therapeutic procedures) remains the 
responsibility of the subject’s treating physician.
The investigator will inform the sponsor immediately of any urgent safety measures taken to 
protect the trial subjects against any immediate hazard, as well as of any serious breaches of 
the protocol or of ICH GCP.
The Boehringer Ingelheim transparency and publication policy can be found on the following 
web page: trials.boehringer-ingelheim.com. As a general rule, no trial results should be 
published prior to archiving of the CTR.
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 Institutional Review Board (IRB) / Independent Ethics Committee 
(IEC) and competent authority (CA) according to national and international regulations. The 
same applies for the implementation of changes introduced by amendments.
Prior to 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.
Re-consenting may become necessary when new relevant information becomes available and 
should be conducted according to the sponsor’s instructions.
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.
ClinBaseTM
In the Human Pharmacology Centre (HPC) – Boehringer Ingelheim's Phase I unit – the 
validated ClinBaseTM system is used for processing information and controlling data 
collected in clinical studies. In addition to its function as a procedure control system, 
ClinBaseTM serves as data base. Instead of being entered into CRFs, selected data are directly 
entered into the system.
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:

meets all inclusion criteria and does not meet any exclusion criteria. The absence of 
records (either medical records, verbal documented feedback of the subject or testing 
conducted specific for a protocol) to support inclusion/exclusion criteria does not 
make the subject eligible for the clinical trial.
Data directly entered into ClinBaseTM (that is, without prior written or electronic record) are 
considered to be source data. The place where data are entered first will be defined in a trial 
specific Source Data Agreement. The data in ClinBaseTM are available for inspection at any 
time.
8.3.2
Direct access to source data and documents
The investigator /institution will allow site trial-related monitoring, audits, IRB / IEC review 
and regulatory inspections. Direct access must be provided to the CRF and all source 
documents/data, including progress notes, copies of laboratory and medical test results, which 
must be available at all times for review by the Clinical Research Associate, auditor and 
regulatory inspector (e.g. FDA). They may review all CRFs and informed consents. The 
accuracy of the data will be verified by direct comparison with the source documents 
described in section 8.3.1. The sponsor will also monitor compliance with the protocol and 
GCP.
8.3.3
