There will be a washout period of at least 4 days between treatments, i.e. the dose in 
the preceding treatment period and the dose in the following treatment period will 
be separated by at least 4 days.
Statistical methods
Preliminary pharmacokinetic analyses and simulations will be performed between 
trial part 1 and trial part 2A as, well as between part 2A and 2B, 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.
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, spleen tyrosine kinase (SYK) inhibitor being developed for 
the indication of uncontrolled, severe, and persistent asthma.
This trial will be performed to select one formulation principle (extended release (ER) tablet
vs. ER capsule) and to optimize the selected ER formulation.
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 basophil-, mast-, B- and T cells. SYK is essential for the FcεR1-mediated 
activation and degranulation of mast- and basophil cells. 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- and T cell development, with 
partially redundant functions with Zeta-chain-associated protein kinase of 70 kDa (ZAP70) 
[R15-5470, R16-5298].

Brochure (IB) [c03536505].

No SAEs and no AESI were observed in this dose group. Patient 
 with elevated liver and 
CK- values received placebo. All other adverse events as well as changes from base line of 
laboratory, ECG and vital sign parameters were of minor clinical relevance.
The corresponding pharmacokinetic geometric mean parameters were 2330 nM for Cmax and 
15100 nM*h for AUC0-24. These values were slightly higher than those in the first-in-man 
study 1371-0001 after a single 70 mg dose of BI 894416 with a geometric mean Cmax of 
2,130 nM and a geometric mean AUC0-24 of 11,100 nM*h.
In conclusion, a single 75 mg dose of BI 894416 was well tolerated and safe. The systemic 
and peak exposure was similar to that seen in study 1371-0001 after a single dose of 70 mg.

RATIONALE FOR PERFORMING THE TRIAL
Preclinical pharmacokinetic/ pharmacodynamic modelling showed that
 
 
 
 is necessary to achieve full clinical efficacy in humans.
Based on data from trial 1371-0001, thrice daily administration of an immediate release 
formulation (IR) would be necessary to achieve this goal.
With an ER formulation a twice daily dosing regimen is expected to result in BI 894416 
plasma concentrations corresponding to an 
 with a lower total daily 
systemic exposure compared to that of the IR formulation. Twice daily dosing might also be 
associated with higher patient convenience and compliance.
In trial part 1, oral ER tablet and capsule formulations, based on different release principles,
will be tested, to identify the formulation that would most reliably lead to a therapeutically 
relevant exposure (i.e. concentrations corresponding to an
when single 
dose pharmacokinetics is simulated to steady state under fasted and fed conditions.
If necessary, the formulation selected in trial part 1 would be further optimized in trial part 2 
with regards to dose and drug release. This could either result in (i) an increased
for 
better target inhibition and/ or (ii) a lower potential food effect to achieve a more stable target 
inhibition and/ or (iii) a reduced variability of the pharmacokinetics for a more consistent 
target inhibition in the study population.

The Clinical Trial Authorisation (CTA) application for this study describes a flexible protocol 
design using the concept of formulation design space /a bracketed dose approach to allow 
decision-making in response to interim pharmacokinetic 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 
).
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 File Note 
and approved by the sponsor and a 
 representative ahead of 
manufacture.

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 medical 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 alternative to 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.
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.
Electrocardiogram 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.
1.4.3
Risks related to BI 894416 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- and B cells. For 
further details, refer to the most recent 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. For further details, refer also to the most recent 
IB [c03536505]).

Due to the reversible mode of action of BI 894416 with regard 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 (refer to Section 3.3.3,).
Adverse events will be monitored for an increase in infectious adverse events. Safety 
laboratory will contain 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 mice, but not related to SYK inhibition. Allelic deletion of SYK has been 
associated with breast adenocarcinoma [R15-4770]. However, there is no evidence that

001-MCS-40-106-RD-13 (6.0) / Saved on: 13 Jun 2018
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 will be included in this trial. In view of 
the extended time necessary to induce a carcinogenic effect, a maximum of 6 single doses of 
BI 894416 are not considered to be a relevant carcinogenic risk to male subjects, participating 
in this study. Accordingly, no further measures of risk mitigation are thought to be required 
in this study.
Platelet aggregation and bleeding risk
A role of SYK in platelet function has been demonstrated in the 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, respectively. In general, platelet function, as measured by bleeding time,
should not be affected by a drug after the administration of a single dose. Therefore, the risk 
for bleeding is considered to be low with regard to platelet inhibition, unless a subject is also 
on other antiplatelet drugs that block other pathways. In line with this conclusion, data of 
previous trial 1371-0001 did not indicate any signs of an increased risk of bleeding.
Risk mitigation and monitoring: Use of any other concomitant drugs that could reasonably 
inhibit platelet aggregation or coagulation (e.g. acetylsalicylic acid) will be prohibited in this 
trial (refer also to Sections 3.3.3 and 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, refer to the most recent version of the IB [c03536505]. In this trial, each subject is 
treated with a maximum of 6 single doses of BI 894416. Due to comparatively slow turnover 
of bone tissue, no relevant effect on bone is expected, and no specific monitoring of bone 
density is necessary or reasonable in this trial.
Mortality/ morbidity in preclinical studies
Due to overt morbidity that occurred in toxicological studies with CByB6F1 non-transgenic 
mice and in Wistar Han rats, some animals died or had to be sacrificed. Clinical signs 
preceding morbidity were similar in both rodent species and included respiratory changes 
(rapid, shallow, and/ or laboured breathing), decreased motor activity, ruffled fur, hunched or 
prostrate posture, eye changes (squinting, discharge) and/ or hypothermia. These findings
occurred at exposures of ≥723,000 nM*h which is equivalent to 20-fold of the human 
exposure cap. One dog of the 3-day escalation study was sacrificed due to overt 
neurotoxicity. For details, refer to the most recent IB [c03536505].

Risk mitigation and monitoring: Data of trial 1371-0001 indicate good safety and tolerability 
of BI 894416 at all investigated doses (single oral doses of up to 70 mg). Doses of BI 894416,
given in trial 1371-0022 and expected plasma exposures are about the same as those
previously given to and seen in healthy volunteers, respectively. Moreover, subjects will be 
in-house at the trial site and under close medical observation for 24 h after administration of 
BI 894416. Vital signs and ECGs will be recorded during the trial. Subjects will be instructed 
to report AEs spontaneously and will be asked at pre-defined time points for AEs. In case of 
AEs in need of treatment, the investigator can authorise symptomatic therapy and, if required, 
subjects will be kept under supervision at the trial site or transferred to a hospital, until all 
monitored results will have returned to an acceptable level.
Neurotoxicity
In dog toxicology studies, acute adverse neurological effects with tremor and movement 
disorder, assessed as dyskinesia (paresis/ rigidity), were observed at high exposures (for 
further detail, refer also to most recent IB [c03536505]). One dog was euthanized due to 
overt neurotoxicity in 3-day escalation study at 90 mg/kg/day [n00235423]. In another dose 
escalation study [n00245394], all clinical signs of neurotoxicity were reversible with the 
cessation of dosing. No structural changes were observed in histopathology. Peripheral nerve 
conduction velocity and EEG were unchanged. No specific mechanism causing these
neurological effects in dogs was identified. Although it has not been determined whether or 
not these neurological changes are dog specific, an external expert review considered these 
findings most likely to be a channelopathy specific to dog and not likely to occur in man. For 
more detail, refer also to the most recent IB [c03536505].
Risk mitigation and monitoring: Subjects with relevant neurological disorder in the medical 
history will be excluded from trial participation (refer to Section 3.3.3). Neurological 
examinations, as described in Section 5.2.5.1, will be performed at screening, and subjects 
with clinically relevant findings in this neurological examination will be excluded from study 
participation (refer to Section 3.3.3). If necessary (investigator decision), unscheduled
neurological examinations may be performed at any time during the trial. Relevant findings 
in the neurological examination during the trial will be reported as AEs. If necessary, subjects 
may be sent for further, more specific evaluation and treatment to a local neurologist.
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 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 a risk for exposure of a trial 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 (refer also to Section 3.3.3).
Phototoxicity
Subjects will be advised to avoid direct exposure to sun and UV light during the entire trial
(refer to 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 pro-arrhythmic 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). In this study, the risk of QT prolongation may need 
differential considerations: While the risk might be similar after the administration of 60 mg 
of the IR reference formulation as compared to the trial 1371-0001 in which a single dose of
70 mg was administered, the risk might be lower after the administration of the ER 
formulations, due to the Cmax of BI 894416 which is expected to be lower. Also, in trial 1371-
0008 after a single dose of 75 mg, no ECG changes were noted.
Risk mitigation and monitoring: Subjects with cardiovascular disorders (refer also to 
Section 3.3.3), subjects who have been using drugs that cause QT/QTc prolongation (refer 
also to Section 3.3.3), subjects who show a marked baseline prolongation of QT/QTc interval 
or any other relevant ECG finding at screening (refer also to Section 3.3.3), and subjects with 
a history of additional risk factors for Torsade de Pointes arrhythmia (refer also to 
Section 3.3.3) will be excluded from trial participation. Moreover, subjects will be in-house
under close observation for 72 h following drug administration, and ECGs are registered pre-
and post-dose at the time points given in the Flow Chart. Considering these risk-mitigating
measures, the risk to subjects participating in this trial due to potential effects on the QT 
interval are considered minimal.
1.4.4
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. For further information, refer to Section 5.2.6.1.4, adverse events of special interest.
1.4.5
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 of up 
to 4 weeks duration to man.

Data of previous trials 1371-0001 and 1371-0008 indicate good safety and tolerability of 
single oral doses of BI 894416 at all dose levels up to 70 mg and 75 mg, respectively. 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. 
For details, refer to the most recent IB [c03536505]).
BI 894416 plasma exposures in this trial are expected to be within the range of those values 
that were observed in the first-in-man trial 1371-0001 and that were associated with good 
safety and tolerability.
Considering the medical need for a better treatment in severe asthma and taking into account 
the (so far) known safety profile of BI 894416, characterised in trials 1371-0001 (single 
rising dose, first in man), 1371-0021 (food interaction), 1371-0004 (itraconazole interaction)
and the ongoing 1371-0008, the expected benefit is likely to outweigh the potential risks and 
justifies exposure of healthy volunteers.

OVERALL TRIAL DESIGN AND PLAN
The study will be performed in healthy male subjects as an open-label, randomised, single-
dose study in two parts. For a depiction of the overall study design, refer to Figure 3.1: 1.
Figure 3.1: 1
Example of the overall study design
Trial part 1 (n=24) will be performed as a five-period crossover design in order to compare
test treatments T1 to T4 to the reference treatment R1. These treatments will be administered 
under fasted conditions and in one of the following 5 sequences, T3-R1-T1-T4-T2, T2-T1-
T3-R1-T4, T4-T3-R1-T2-T1, T1-T4-T2-T3-R1, R1-T2-T4-T1-T3. Test treatments T5 or T6 
will be added as the sixth treatment period. These treatments will be administered under fed
conditions.
Trial part 2 (n=18) is optional and will be split in two parts. Trial part 2A will be performed 
as a three-period crossover design, with sequences T7-T8-R2, R2-T7-T8 and T8-R2-T7, to 
compare treatments T7 and T8 to the reference treatment R2. If appropriate, trial part 2B will 
follow as a two-period crossover design, with sequences T9-T10 and T10-T9, in order to 
compare test treatments T9 and T10.
A single dose of each treatment will be administered as follows:
Trial part 1

At least 10 of the other subjects of part 1 (fixed sequence part)

T6- Prototype Formulation F2: 62.5 mg BI 894416, after high-fat, high-calorie 
breakfast (n≥10)
Decision point: either (a) stop here or (b) proceed to trial part 2A with either optimised 
formulations G (tablet) or I (capsule), as T7 under fasted conditions and T8 after a high-fat, 
high-calorie breakfast.
Decision rules:
The decision will be based on data of a minimum of 16 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 58h post-dose, and (iii) 
pharmacokinetic simulations, using an existing model which was based on pharmacokinetic 
data of Phase I studies.
Criteria to stop after trial part 1 will be:

Pharmacokinetic simulations to steady state demonstrate a Cmin
 under 
fasted and fed conditions and further optimization of the formulation with regards to 
dose and drug release is not expected to improve pharmacokinetic properties.

Pharmacokinetic simulations to steady state indicate that Cmin
 cannot 
be achieved under fasted and/ or fed conditions even considering dose and drug 
release optimization.
For additional discontinuation criteria, refer to Section 3.3.4.3.
Criteria to continue after trial part 1 will be:

Pharmacokinetic simulations to steady state demonstrate a Cmin ≥ 
 under 
fasted and/ or fed conditions and further optimization of formulation with regards to 
dose and drug release is expected to improve pharmacokinetic properties

Pharmacokinetic simulations to steady state demonstrate a Cmin
 under 
fasted and/ or fed conditions and further optimization of formulation with regards to 
dose and drug release is expected to improve to a Cmin
Improved pharmacokinetic properties would be (i) a reduced food effect, (ii) a higher 
at 
a similar or even reduced dose, (iii) a smaller peak to trough ratio at simulated steady state 
pharmacokinetics, (iv) possibly reduced variability of pharmacokinetic parameters. The 
optimization would be guided by (i) the formulation principle (ER tablet vs. ER capsule), (ii) 
the release rate (and profile) and (iii) the dose.
If optimization is considered possible, formulations G (ER tablet) or I (ER capsule) will be 
developed and further tested in trial part 2A.
In case, both ER tablet formulation or ER capsule formulation would qualify for 
optimization, a decision will be made based on available data.
Trial part 2 (optional)
Trial part 2A (only one, either G or I will be tested in the fasted and fed state)

R2-Reference Formulation 2: 60 mg BI 894416, fasted (n=18)

There will be a washout period of at least 4 days between the treatments, i.e. the dose in the 
preceding treatment period and the dose in the following treatment period are separated by at 
least 4 days.
Subjects will be randomly allocated to the different treatment sequences. For details, refer to 
Section 4.1.
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.
3.2
DISCUSSION OF TRIAL DESIGN, INCLUDING THE CHOICE OF 
CONTROL GROUPS
3.2.1
Discussion of study design
All trial parts
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 provided by a 
bioanalytical laboratory that is blinded to treatment allocation.
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].
Period 6 of trial part 1 (fixed sequence)
A fixed-sequence design was selected in which BI 894416 Formulation C2 (T5) or 
Formulation F2 (T6) was administered in the sixth study period after a high-fat, high-calorie 
breakfast. The fixed-sequence design is not expected to lead to systematic errors in the 
estimation of the treatment effects since nonspecific time-effects are unlikely due to the short 
trial duration.
3.2.2
Rational for decision rules
The rational for performing this trial is to identify an ER formulation that results in 
therapeutically relevant exposures after twice daily dosing.
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 2A and/ or part 2B. Rules would also guide the termination of the process,
either after trial part 1 or trial part 2A, if no successful formulation was to be achieved.
3.3
SELECTION OF TRIAL POPULATION
It is planned that a total of 42 healthy male subjects will enter the trial, 24 in trial part 1 and 
18 in trial part 2. 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 12 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.
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 (refer 
also to the most recent 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:
1. Healthy male subjects according to the assessment of the investigator, as 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) at the time of signing informed consent
3. BMI of 18.5 to 29.9 kg/m2 (inclusive) as measured at screening
4. Signed and dated written informed consent prior to admission to the study, in accordance 
with GCP and local legislation
5. 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:

Condoms plus use of hormonal contraception by the female partner that started at 
least 2 months prior to administration of trial medication (e.g., implants, injectables, 
combined oral or vaginal contraceptives, intrauterine device) or

Condoms plus surgical sterilization (vasectomy at least 1 year prior to enrolment) or

Condoms plus surgically sterilised partner (including hysterectomy) or

Condoms plus intrauterine device or

Condoms plus partner of non-childbearing potential (including homosexual men)
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.

until 30 days after the last administration of trial medication
28. Subjects with pregnant or lactating partners
For study restrictions, refer to Section 4.2.2.
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. For details, refer to 
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.
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 including 
but not limited to:
Corrected QT interval by Fridericia’s formula (QTcF) interval 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. Refer also to 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 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
The investigator/ trial site will be reimbursed for reasonable expenses incurred in case of trial 
termination (except, if item 3 applies).
Stopping Criteria
The study will be halted, and the risk to other subjects evaluated, if any of the following 
criteria are met:

A serious adverse reaction (i.e., a serious AE considered at least possibly related to the 
IMP administration) in one subject.

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 ( cohort 
refers to subjects receiving the same treatment), independent of within or not within the
same system organ class.
3.3.5
Replacement of subjects
In case of more than 4 subjects in trial part 1 and 4 subjects in trial part 2 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 and which regimens they 
are required to complete. A total of maximum 8 subjects will be replaced in the whole trial. A 
replacement subject will be assigned a unique trial subject number, and will be assigned to 
the same treatment as the subject he replaces.
In trial part 1, up to 8 replacement subjects may be enrolled into the study. The maximum 
number of replacement subjects that may be dosed is 4.
In trial part 2, up to 8 replacement subjects may be enrolled into the study. The maximum 
number of replacement subjects that may be dosed is 4.
Subjects withdrawn due to an IMP-related AE or termination of the study will not be 
replaced.
Subjects who are withdrawn for other reasons may be replaced at the discretion of the 
investigator and sponsor to ensure sufficient evaluable subjects.
For trial part1 and 2, replacement subjects will complete the entire sequence.

4.1.2
Selection of doses in the trial and dose modifications
The doses selected for the ER tablet or ER capsule are expected to result in clinically relevant 
BI 894416 exposures. Dose modification within a defined range would become necessary, if 
the extent of absorption from a ER formulation differed from that of the IR formulation.
4.1.3
Method of assigning subjects to treatment groups
The randomisation list will be provided to the trial site in advance.
According to the planned sample size of trial part 1(n=24), 2 cohorts (12 subjects each) are 
planned. Each subject will be allocated to one of 10 treatment sequences (R1, T1 to T4 and 
T5, or R1, T1 to T4 and T6). For details, refer to Section 7.6.
According to the planned sample size of trial part 2 (n=18), each subject will be allocated to 
one of five treatment sequence (R2, T7 to T10). For details, refer to Section 7.6.
Prior to the start of the study, subjects willing to participate will be recruited to cohorts 
according to their temporal availability. In the morning of Day 1 (Visit 2), subjects will be 
allocated to treatment sequences prior to the first administration of trial medication. For this 
purpose, numbers of the randomisation list will be allocated to the subjects sequentially just 
prior to first dosing by using the method ‘first come, first served’. Subjects are then assigned 
to a treatment sequence according to the randomisation list. Hence, no bias is introduced 
when providing the randomization list in advance to the site. Reference and test treatments 
will be administered in the sequence specified in the Flow Chart.
Once a subject number has been assigned, it cannot be reassigned to any other subject.
The randomisation procedure is described in Section 7.6.
4.1.4
Drug assignment and administration of doses for each subject
This trial is an open-label, randomised, single-dose study in two parts.
All 24 subjects of trial part 1 will receive six treatments in randomised order as a five-period 
crossover design with an additional sixth period as a fixed sequence.
All 18 subjects of trial part 2 will receive in randomised order first three treatments in a three-
period crossover design, followed by two treatments in a two-period crossover design (if 
appropriate).
Trial part 1
The treatments to be evaluated in trial part 1 are outlined in Table 4.1.4: 1 below.

In trial part 1, in the first five periods, administration of trial medication will be performed 
after all 24 subjects have fasted overnight. Fasting is to start no later than 10 h before the 
scheduled dosing. In the sixth period (T5 and T6), administration of trial medication will be 
performed under fed condition. A high-fat, high-calorie meal (for details, refer to Table
4.1.4: 3) will be served 30 min before drug administration. At least 10 subjects (n≥10) will 
receive treatment 5, at least 10 of the other subjects (n≥10) will receive treatment 6.
The investigator (or authorised designee) will administer the trial medication as an oral dose 
together with about 240 mL of water to subjects in a 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.

Trial part 1 and 2
In certain treatment periods, as stipulated above, 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: 3; this meal is in compliance with the FDA guidance ‘Food-Effect
Bioavailability and Fed Bioequivalence Studies’ [R03-2269]. For restrictions with regard to 
diet, refer to Section 4.2.2.2.
Table 4.1.4: 3
Composition of the high-fat, high-calorie meal
Ingredients
1 chicken eggs (whole content) for fried eggs
10 g butter for frying eggs

The total caloric content was supplied approximately as following: 144 kcal as protein, 280 kcal 
as carbohydrate, and 486 kcal as fat.
Subjects will be kept under close medical surveillance until 72 h after drug administration.
During the first 2 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, except medical 
examination and assessments).
The treatments will be separated by a wash-out phase of at least 4 days.
4.1.5
Blinding and procedures for unblinding
This 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 is known to 
investigators and subjects.

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.

Alcoholic beverages are not permitted from 2 days before screening and the first 
administration of trial medication in the first period until discharge from the unit at each 
study period (where applicable).
Smoking is not allowed 3 months prior to screening and during the trial.
Barbecued meat and broccoli should be avoided during the trial.
Methylxanthine-containing drinks or foods (such as coffee, tea, cola, energy drinks, or 
chocolate) are not allowed from 10 h before until 24 h after each administration of 
BI 894416.
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.
Direct exposure to the sun or exposure to solarium radiation should be avoided during the 
entire study.
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.
Mouth and hand checks will be conducted after dosing to ensure the tablet(s)/ capsule has 
been swallowed.
The date and time that each subject is dosed will be recorded in the subject’s source data. 
Any violation of compliance will require evaluation by the investigator and sponsor to 
determine if the subject can continue in the study.
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, refer to Section 3.3.4.1).

a supine position. All recordings should be made using the same type of blood pressure 
recording instrument on the same arm, if possible.
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. For all safety laboratory sets A and B,
subjects should be 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.

The tests listed in Table 5.2.3: 2 are exclusionary laboratory tests that may be repeated as 
required. The results will not be entered in the CRF/ database and will not be reported in the 
CTR. Except for drug screening, it is planned to perform these tests during screening only. 
Drug screening will be performed at screening and prior to each treatment period.

Electrocardiogram
Twelve-lead ECGs (I, II, III, aVR, aVL, aVF, V1 - V6) will be recorded using a 
computerised electrocardiograph (
 ELI 250) 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 as paper copies. 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). Precise electrode placement will be marked with an 
indelible mark on the skin to allow reproducible placement throughout the study.

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.

Other safety parameters
5.2.5.1
Neurological examination
At Screening and at EoT examination, 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.

001-MCS-40-106-RD-13 (6.0) / Saved on: 13 Jun 2018
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 jeopardize the patient and may 
require medical or surgical intervention to prevent one of the other outcomes listed in 
the above definitions. Examples of such events are intensive treatment in an 
emergency room or at home for allergic bronchospasm, blood dyscrasias or 
convulsions that do not result in hospitalization 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 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.
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, refer to 
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 or eDC system, as applicable. 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.
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, i.e. signature of the informed consent form, 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 immediately (within 24 hours) to the sponsor’s 
unique entry point (country specific reporting process 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 send 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.
5.2.6.2.4
Pregnancy
Once the male subject has been enrolled in the clinical trial and has taken trial medication, 
and if a partner of the male trial participant becomes pregnant, the investigator must report 
any drug exposure during pregnancy in a partner of the male trial participant immediately 
(within 24 hours) by means of Part A of the Pregnancy Monitoring Form to the sponsor’s 
unique entry point, after a written consent of the pregnant partner. The outcome of the 
pregnancy associated with the drug exposure during pregnancy must be followed up and 
reported to the sponsor’s unique entry point on the Pregnancy Monitoring Form for Clinical 
Trials (Part B).
The ISF will contain the Pregnancy Monitoring Form for Clinical Trials (Part A and Part B) 
as well as non-trial specific information and consent for the pregnant partner. As pregnancy 
itself is not to be reported as an AE, in the absence of an accompanying SAE and/ or AESI, 
only the Pregnancy Monitoring Form for Clinical Trials and not the SAE form is to be

pharmacokinetic parameters.
5.3.2
Methods of sample collection
5.3.2.1
Blood sampling for pharmacokinetic analysis
BI 894416
For quantification of BI 894416 concentrations in plasma, approximately 2.0 mL of blood 
will be drawn from an antecubital or forearm vein into a 
 
 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.
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.
Further use of samples
After the completion of BI 894416-quantification in plasma aliquots, the left-over and/ or 
back-up aliquots 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.
Results of any further investigations are not planned to be part of the CTR but can be 
included into the CTR, if necessary.

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,
2.1.2, 2.1.3, and 2.2.2.1 are generally used assessments of drug exposure.
Due to reversible neurologic effects observed in dog studies at high exposures, 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 
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 safety laboratory 
tests will be ± 30 min within 4 hours after administration and ±60 min thereafter.
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 ± 60 min will be 
allowed for PK samples.
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- and neurological examination, refer to Sections 5.2.1 to 5.2.5.
This study permits the re-screening of a subject who has discontinued the study as a pre-
treatment failure (i.e., subject has not been randomised/ has not been treated); the reason for 
failure must be temporary and expected to resolve. If re-screened, the subject must be re-
consented.
The identity of the subjects will be confirmed at admission and pre-dose. The subjects will be 
admitted to the clinical unit on the evening before dosing (Day -1). The admission and pre-
dose procedures are presented in Flow Chart. In addition, the ongoing eligibility of subjects 
will be re-assessed at admission/ pre-dose, as described in Flow Chart.

6.2.2
Treatment periods
Samples for genotyping will be taken from all subjects prior to first drug administration in
period 1 (for details, refer to Section 5.5.1).
Trial part 1
Each subject is expected to participate in 6 treatment periods. At least 4 days will separate 
drug administrations between treatment periods.
On Day -1 of the first treatment period, study participants will be admitted to the trial site and 
kept under close medical surveillance for at least 72 h following the last drug administration. 
Subjects will then be allowed to leave the trial site after formal assessment and confirmation 
of their fitness.
For details on time points and procedures for collection of plasma samples for 
pharmacokinetic analysis, refer to Flow Chart and Section 5.3.2.
The safety measurements performed during the treatment period are specified in Section 5.2, 
their sampling time points are in 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.
Decision making and procedures after trial part 1
After completion of trial part 1, a preliminary pharmacokinetic analysis will be performed
(for details, refer to Section 7.4). On the basis of these data and supported by 
pharmacokinetic simulations, the sponsor will decide on whether (i) at least one formulation 
will meet the requirements for use in future clinical studies, or (ii) no formulation will meet 
the requirements and an improvement is not possible, or (iii) a formulation principle can be 
improved and needs to be further optimized. In case of (i) and (ii) the trial will be stopped. In 
case of (iii) the trial will be continued with trial part 2A. For details on decision rules, refer to 
Section 3.1. Should the study be continued, a batch of modified study medication will be 
produced and provided by 
 This medication will then be used in trial part 2A.
A formal and documented formulation selection review will take place after trial part 1.
The review can be conducted face-to-face or by video/ telephone conference. The Clinical

Decision making and procedures after trial part 2A
After completion of trial part 2A, a preliminary pharmacokinetic analysis will be performed 
(for details, refer to Section 7.4). On the basis of these data and supported by 
pharmacokinetic simulations, the sponsor will decide on whether (i) the formulation will 
meet the requirements for use in future clinical studies, or (ii) the formulation will not meet 
the requirements and an improvement is not possible, or (iii) a formulation can be improved 
and needs to be further optimized. In case of (i) and (ii) the trial will be stopped. In case of 
(iii) the trial will be continued with trial part 2B. For details on decision rules, refer to 
Section 3.1. Should the study be continued, a batch of modified study medication will be

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 extended release 
formulations compared with the immediate release formulation, following oral administration
under fasted and fed conditions on the basis of the primary and secondary pharmacokinetic 
endpoints, as listed in Sections 2.1.2 and 2.1.3.
In addition relative bioavailability between selected extended release formulations will be 
investigated. The trial is designed to allow intra-subject comparisons and will be evaluated 
statistically by use of a linear model for logarithmically transformed pharmacokinetic 
endpoints.
A further objective is to evaluate and compare further pharmacokinetic parameters between 
the treatments.
In addition the assessment of safety will be evaluated for the parameters specified in 
Section 2.2.2.2.
All parameters will be assessed descriptively.
7.2
NULL AND ALTERNATIVE HYPOTHESES
The relative bioavailability of the reference formulation will be compared with the test 
formulations, the ratios of the geometric means (test/ reference), and their corresponding
2-sided 90% confidence intervals (CIs) will be provided. In addition, relative bioavailability 
between selected extended release formulations will be investigated in the same way as 
between test and reference. 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 randomized 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 pharmacokinetic endpoint that was defined 
as primary or secondary and was not excluded due to a protocol violation relevant to 
the evaluation of pharmacokinetics or due to pharmacokinetic non-evaluability (as 
specified in the following subsection ‘Pharmacokinetics’). Descriptive and model 
based analyses of pharmacokinetic parameters will be based on the PKS.

Adherence to the protocol will be assessed by the trial team. Important protocol deviations
(IPD) categories will be described in the 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 BI SOP ‘Standards and processes for analyses performed within 
Clinical Pharmacokinetics/ Pharmacodynamics’ [001-MCS-36-472].
Plasma concentration data and parameters of a subject will be included in the statistical 
pharmacokinetic analyses if they are not flagged for exclusion due to a protocol violation 
relevant to the evaluation of pharmacokinetics (to be decided no later than in the Report 
Planning Meeting) or due to pharmacokinetic 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 that occurred at or before two times median tmax of 
the respective treatment (median tmax is to be determined excluding the subjects 
experiencing emesis)

Missing samples/ concentration data at important phases of pharmacokinetic 
disposition curve
Plasma concentration data and parameters of a subject which is flagged for exclusion will be 
listed with its individual values but will not be included in the statistical analyses. Descriptive 
statistics of pharmacokinetic 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
Primary analyses
The statistical model used for the analysis of the primary endpoints will be an analysis of 
variance (ANOVA) model on the logarithmic scale. That is, the pharmacokinetic endpoints 
will be log-transformed (natural logarithm) prior to fitting the mixed model.

The pairwise comparisons of R1 with T1, T2, T3 and T4 will be analyzed in a five-way 
crossover model. This model will include effects accounting for the following sources of 
variation: sequence, subjects nested 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 
treatmentk in period j,
= the overall mean,
i = the ith sequence effect
sim = the effect associated with the mth subject in the ith sequence
j = the jth period effect
k = the kth treatment effect
eijkm = the random error associated with the mth subject in sequence i who received
treatment k in period j.
where sim ~ N	0,σB
2 i.i.d., eijkm ~ N	0,σW
2  i.i.d. and sim, eijkm are independent random 
variables.
The fasted vs fed comparisons (T2 - T5 and T4 - T6) will be analyzed as a two period fixed 
sequence cross-over model. The model used will include effects accounting for the following 
sources of variation: subjects and treatment. The effect ’subjects’ will be considered as 
random, whereas the effect ‘treatment’ will be considered as fixed. The model is described by 
the following equation:
ykm = + sm + k + ekm, where
           ykm = logarithm of response measured on subject m receiving treatment k,
           = the overall mean,
           sm = the effect associated with subject m
           k = the kth treatment effect
           ekm = the random error associated with subject m receiving treatment k.
where sm ~ N	0,σB

Point estimates for the ratios of the geometric means (test/ reference) for the primary 
endpoints (refer to Section 2.1) and their two-sided 90% confidence intervals (CIs) will be 
provided.
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 (which corresponds to the two one-
sided t-test procedure, each at a 5% significance level) based on the residual error from the 
ANOVA and will be back-transformed to the original scale to provide the point estimate and 
90% CIs for the ratio T/R.
Further exploratory analyses
The same statistical model as stated above will be repeated for the primary endpoints 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.
If an analysis model fails to converge or is not suitable, the model will be simplified.
7.3.2
Secondary endpoint analyses
The secondary endpoint (refer to Section 2.1.3) will be analysed in the same way as the 
primary endpoint.
7.3.3
Further endpoint analyses
7.3.3.1
Pharmacokinetic analyses
Further endpoints (refer to Section 2.2.2) will be analysed in the same way as 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 statistical comparison between 
treatment groups for safety data is planned, unless otherwise specified within the relevant 
section.
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 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 (refer to 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 (refer to 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 (refer to 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
No inferential statistical interim analysis is planned.
After trial part 1, a preliminary analysis of pharmacokinetic parameters e.g. AUC0-∞or AUC0-
tz, 
of BI 894416, provided as individual values and geometric means, will be 
performed for all tested formulations and modes of administration (fasted or fed). 
Pharmacokinetic simulations will be used as basis for prediction of steady state exposures. 
Further details will be described in a separate analysis plan. Similar analyses will be 
performed after trial part 2A, if appropriate.
In contrast to the final pharmacokinetic 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 results will be distributed to the investigator and the trial

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

Prior to allocation of a subject to a treatment into a clinical trial, there must be 
documented evidence in the source data (e.g. medical records) that the trial participant 
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
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
Storage period of records
Trial site:
The trial site must retain the source and essential documents (including ISF) according to

Throughout the document
Description of change
Adaptation of the wording to the statistical scenarios
Minor editorial and formatting changes throughout 
the document
Rationale for change
Since block- and sample size do not match, an 
imbalances between treatment 5 and treatment 6 is 
anticipated. Therefore, the wording was adapted in 
the Synopsis, as well as in Sections 3.1 and 4.1.4 to 
rectify the wording and the statistical model was 
adapted in the Synopsis and Section 7.3.1.
Non-substantial’, because no major changes to the 
primary and secondary objectives were made
Minor editorial and formatting changes for
consistency reasons
