2. Safety laboratory to be taken and to be medically evaluated on Day -1 prior to administration of BI 894416; 
this ambulatory visit including safety laboratory, neurological exam, ECG and adverse event questioning can 
be omitted if the screening examination is performed on Day -3 or -2.
3. Oral with 240 mL of water after an overnight fast of at least 10 h; (please also refer to Section 4.2.2.2)
4. If several actions are indicated at the same time point, the intake of meals will be the last action.
5. EOT includes medical examination, neurological examination, vital signs, ECG, safety laboratory, recording 
of AEs and concomitant therapies.
6. Letters A, B and C describe different sets of safety laboratory examinations (see Section 5.2.3).
7. Drug screening will be performed at screening and prior to dosing at Day 1 of visit 2. A breath alcohol test 
and cotinine test will be performed during screening and prior to BI 894416 or placebo administration at 
Visit 2, and may be repeated at any time during the trial at the discretion of an investigator or designee. 
8.
PK samples for determination of plasma level of BI 894416 as detailed in Section 5.3.2 Sampling times and 
periods may be adapted based on information obtained during the trial (e.g. preliminary PK data) including 
addition of samples and visits as long as the total blood volume taken does not exceed approximately 500 
mL per subject.
9. For allowed deviation from the scheduled time please refer to Section 6.1.
10. PK samplings and ECGs should be done in direct sequence to allow for a time-matched pair of ECG 
recordings and plasma concentration of BI 894416.
11. PK urine samples for determination of BI 894416 amount eliminated in urine are to be taken at following 
time intervals: a blank urine sample is to be obtained within 3 h prior to administration of trial medication;
other urine samples are to be collected over the stated post-dose intervals 0-4, 4-8, 8-12, 12-24 and 24-48 h 
(see Section 5.3.2.2).
12. Three triplicate ECGs are recorded within approximately 1 h. The recordings of each triplicates should be 
separated by at least 15 min (refer to the Section 5.2.4.1).
13. Triplicate ECG (refer to the Section 5.2.4.1).
14. Continuous ECG monitoring to be done starting at least 15 min before BI 894416, or placebo, administration 
and for at least 4 h following BI 894416, or placebo (3-lead ECG recording).
15. AEs and concomitant therapies will be recorded throughout the trial, but will be specifically asked for at the 
time points indicated in the Flow Chart.

1.
INTRODUCTION
BI 894416 is a selective inhibitor of the non-receptor protein tyrosine kinase SYK (spleen 
tyrosine kinase) and is under clinical development to be orally administered for the indication 
of uncontrolled severe persistent asthma.
This trial will be performed to investigate the safety, tolerability, and pharmacokinetics of 
single rising oral doses of BI 894416 versus placebo in healthy Japanese male subjects.
1.1
MEDICAL BACKGROUND
Asthma is a heterogeneous disease characterized by a chronic inflammatory process of the 
airways and is 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, natural killer (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-cells, 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, which are present 
on macrophages, dendritic cells, and neutrophils. Furthermore, SYK has important roles in B-
cell and T-cell development, having 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.
Clinical Experience in Humans
1.2.1
Summary of clinical trials
1.2.1.1
So far, BI 894416 was investigated in 4 phase I clinical trials in healthy male subjects and in 
one phase I clinical trial in mild asthma patients. Trial 1371-0001 was a first-in-man trial,
trial 1371-0004 was a trial to investigate drug-drug interaction, trial 1371-0021 investigated 
the effect of a high-fat, high-calorie breakfast on BI 894416 absorption and trial 1371-0005

investigated the drug-drug interaction of rifampicin on BI 894416 metabolism. Trial 1371-
0008 is an ongoing single-rising dose (SRD)/ multiple-rising dose (MRD) trial in mild 
asthma patients.
Trial 1371-0001 consisted of two parts. SRD part and a relative bioavailability (rel BA) part. 
Single-dose treatment up to 70 mg BI 894416, as an oral solution in the SRD part, as well as 
in the relative BA part, was safe and well tolerated. For details on safety and tolerability, as 
well as on pharmacokinetics and biomarker data of trial 1371-0001, refer to the IB 
[c03536505].
Trial 1371-0004 investigated the effect of strong inhibition of CYP3A, as well as the
inhibition of P glycoprotein, on the pharmacokinetics of oral single dose of BI 894416. In this
trial, 3 mg of BI 894416 was given in period 1. Period 2 consisted of a 3-day pre-treatment 
with 200 mg itraconazole being administered once a day, of a fourth dose of itraconazole 
being administered 1 h before BI 894416 administration, and of a fifth dose of itraconazole 
being administered 23 h after BI 894416 administration. Preliminary pharmacokinetic (PK)
data (based on planned time points) indicated that administration of itraconazole increased 
the geometric mean (gMean) of Cmax, AUC (area under the curve) 0-tz, and AUC0-∞of 
BI 894416 in plasma by 1.13, 1.42, and 1.43 fold respectively. BI 894416, alone or together 
with itraconazole, was assessed as safe and well-tolerated in trial 1371-0004. For more details 
refer to the IB [c03536505].
Trial 1371-0021 investigated the relative bioavailability of BI 894416 as tablet formulation 
following a high-fat, high calorie breakfast compared with administration in the fasting state. 
When 30 mg BI 894416 was administered as immediate release tablets after high-fat high 
calorie meal, Cmax was reduced by approximately 30% with a 2 h delay of tmax. AUC0-tz and 
AUC0-∞were not changed by food intake. BI 894416 immediate release tablets can therefore 
be taken under fasting and fed conditions. For more details refer to the IB [c03536505].
Drug interaction of BI 894416 at a dose of 50 mg with strong CYP3A4- and P-gp-inducer
Rifampicin has been investigated in trial 1371-0005. Relative bioavailability of BI 894416 
after 600 mg once daily Rifampicin administration decreased to 10.48% for AUC0-∞and 
30.03% for Cmax.
Trial 1371-0008 is a combined SRD and MRD trial conducted in mild asthma patients in 
Germany. As of May 2020, preliminary PK data are available for single doses up to 170 mg 
from the SRD part, and up to 50 mg tid. dosing in the MRD part. In the MRD part a single 
dose was administered on Day 1, followed by 7 d tid. dosing and a single dose on day 9. PK 
profiles were taken on Day 1 and on Day 9.
Clinical pharmacokinetics
1.2.1.2
In the 1371-0008 trial after each dose group, samples were analysed for BI 894416. A 
calculation of preliminary PK parameters was done based on planned sampling times; 
therefore PK parameters in the final Clinical Trial Report (CTR) might deviate. Preliminary 
PK parameters were assessed prior to each dose escalation to ensure that predicted gMean of

Cmax of patients did not exceed 5,233 nM, predicted gMean values for AUC0-24 did not 
exceed the maximum acceptable human exposure of 36,150 nM•h and that the upper limit of 
the 95% prediction interval for AUC0-24 of individual patients in the next dose group did not 
exceed 63,000 nM•h. Preliminary PK data from SRD part are shown in Table 1.2.1.2: 1 and 
from MRD part in Table 1.2.1.2: 2.
SRD part: AUC0-24 and Cmax increased dose proportionally with increasing doses. At 170 mg 
the gMean exposure limit for Cmax was met.
MRD part: trough values (data not shown) indicate that steady state was achieved after 4 
days. After 7 days of tid. dosing, Cmax,ss as well as AUCτ,ss increased with increasing dose and
were well below the exposure limits described above.

1.2.1.3
A total of 186 subjects and patients have completed treatment with BI 894416 as part of 
the Phase I trials. In the completed trials in healthy volunteers, the doses studied ranged 
from 3 mg to 70 mg BI 894416 given as single doses. In the patient trial 1371-0008, doses 
ranged from 75 mg to 170 mg BI 894416 administered as single doses and from 10 mg tid 
to 50 mg tid BI 894416 administered as multiple doses for 7 days.  
Phase I trials in healthy volunteers (1371-0001, 1371-0004, 1371-0005, 1371-0021)
No deaths, serious adverse event (SAE)s, AEs leading to discontinuation, protocol-
specified AESIs, or other significant AEs (according to ICH E3) were reported in the 
Phase I trials. No dose dependent increase in frequency of AEs or drug-related AEs was 
observed with increasing doses of BI 894416 across the range of 3 mg to 70 mg. For more 
details on AEs by individual dose group, please consult the IB [c03536505].

In the ongoing SRD/MRD trial in asthma patients, 46 of the planned 64 patients were 
exposed to BI 894416 and 12 of the planned 16 patients received placebo. A total of 7 
patients received 75 mg BI 894416,  8 patients received 125 mg BI 894416 and 8 patients 
received 170 mg BI 894416 in the single rising dose part of the trial (Table 1.2.1.3: 1). In 
addition, 7 patients received 10 mg tid BI 894416 while 8 patients in each arm of the 25 
mg tid and 50 mg tid BI in the MRD part received BI 894416. None of the patients in this 
trial had SAEs, AESIs (i.e. hepatic injury).
One patient had a severe AE of back pain in the 25 mg tid group. This event was not 
deemed related to trial medication. One patient in the 50 mg tid dose group had an event of 
panic attack which was moderate in intensity and led to discontinuation of trial medication
but was not deemed related to BI 894416. 
Taking into account the number of currently included patients, more patients on BI 894416 
were reported with AEs compared with placebo. The AE, which was most frequently 
reported after intake of BI 894416, was headache (overall 14 of 29 patients in the SRD
portion (48.3%) and 6 of 29 patients in the MRD portion (20.7%). Two patients on placebo in 
the MRD reported headache while the other reported events of headache were taking BI 
894416 in SRD and MRD parts. 
Nausea was reported in 2 of 29 patients in the SRD part (6.9%). Both events were reported in 
the 170 mg dose arm. Nausea was also reported in the MRD part for 1 of 29 patients (3.4%) 
in the 10 mg tid arm. Flatulence was reported for 4 of 29 patients (13.8%) in the 25 mg tid.
One patient reporting flatulence was taking placebo while the remaining three were taking BI 
894416. 
Two patients of 29 (6.9%) in the 25 mg tid dose group reported oropharyngeal pain and both 
patients were on active treatment.  Bronchospasm was reported in 1 patient in the 25 mg tid 
dose group and in 1 patient in the 50 mg tid dose group. Lower respiratory tract infection was 
reported in 1 patient in the 10 mg tid and in 1 patient in the 25 mg tid dose group. All other 
AEs were documented for at most 1 patient overall.
Likewise, headache was mostly classified as drug related by the investigator in 7 of 29 
patients in the SRD part (24.1%) and in 4 of 29 patients (13.8%) in the MRD part. The three 
events of nausea observed in the trial were reported as related to trial medication. Other drug-
related AEs were reported by at most 1 patient per preferred term and included tension 
headache, soft faeces and diarrhoea. 
The events of flatulence reported in the 25 mg tid dose arm were reported as related to trial
procedure as the patients received meals with higher fiber content than their normal diets.  
The safety information displayed for the 1371-0008 trial in patients is preliminary data taken 
from the ongoing trial. As such, the information reported in this protocol may differ slightly 
from the reported AEs in the clinical trial report.

Residual Effect Period
1.2.2
The Residual Effect Period (REP, i.e., the period after the last dose with measurable drug 
levels and/or with pharmacodynamic effects likely to be present) of BI 894416 has not been 
defined yet. However, the elimination half-life of BI 894416 is short (gMean terminal half-
life between 2.96 and 5.31 h in the SRD part of trial 1371-0001) and its mode of action is 
reversible. This suggests that the occurrence of any potential adverse effects would likely be 
limited to a short time period (i.e., few days).
Conservatively, a minimum period of 14 d after last administration of BI 894416, or placebo,
has been selected as the REP. Therefore, the individual subject’s end of trial will be 14 d 
following last dosing with BI 894416, or placebo, at the earliest. 
All adverse events (AE) reported between administration of trial medication and the 
individual subject’s end of trial will be counted as on-treatment AEs.

1.3
RATIONALE FOR PERFORMING THE TRIAL
BI 894416 is an SYK inhibitor that is being developed to be administered orally to treat
patients with severe asthma.
The first single rising dose trial was conducted in healthy volunteers (1371-0001). In trial 
1371-0001 doses of BI 894416 up to 70 mg were given and assessed as safe and well-
tolerated. 
The objective of this trial is to investigate the safety, tolerability, and pharmacokinetics of BI 
894416 in healthy Japanese male subjects. The chosen population of healthy male subjects 
receiving single rising oral doses is considered adequate to provide the basis for the clinical 
development program of BI 894416 in Japan.
In this trial it is intended to investigate the safety and tolerability of 25 mg, 50 mg, and 70 mg
single dose.
The dose range selected for this trial is expected to cover the potential therapeutic dose range 
in the further clinical development program of BI 894416.
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 trial procedures and risks related to the exposure to the trial 
medication.
Procedure-related risks
1.4.1
The use of an indwelling venous catheter or venepuncture for procedures such as blood 
sampling may result in mild bruising and, in rare cases, in transient inflammation of the wall 
of the vein, or in nerve injury that potentially results in paraesthesia, reduced sensibility, 
and/or in 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 trial will not exceed the 
volume of a normal blood donation (approximately 500 mL). No health-related risk to 
healthy subjects is expected from withdrawal of this volume of blood.
To ensure patient safety, all such events or symptoms reported will be managed according to 
the judgement of the Investigator.

Drug -related risks and safety measures
1.4.2
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 of BI 894416 (see also IB [c03536505]).

Due to the reversible mode of action of BI 894416 with regards to SYK inhibition, 
any potential effect on immune cells are expected to be of transient nature.
Risk mitigation and monitoring: Subjects with a history or diagnosis of 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 C-Reactive Protein.
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 SYK inhibitor, BI 1002494, are in line with an absence of 
carcinogenic effect due to the inhibition of SYK enzymatic function [n00243171]. 
Risk mitigation and monitoring: Only male subjects are included in this trial and, in view that 
carcinogenesis is a process that develops over a long time span, single doses of BI 894416 are 
not considered a relevant carcinogenic risk to the male subjects participating in this trial. 
Accordingly, no further risk mitigation is required in this trial. 
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 Glycoprotein VI), but others 
are independent of SYK [R16-5240]. In vitro trials 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 adenosine diphosphate-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. 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. In line with this conclusion, data of previous trial 1371-0001 do not 
indicate any signs of an increased risk of bleeding.
Risk mitigation and monitoring: Use of any other concomitant drug that could reasonably 
inhibit platelet aggregation, or coagulation, such as acetylsalicylic acid, clopidogrel and 
warfarin, will be prohibited (see 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, see the IB [c03536505]. In this trial, each subject is treated with single doses of 
BI 894416. Due to the slow turnover of bone tissue, no relevant effect on bone density is 
expected due to single-dose administrations with BI 894416 in this trial, and no specific 
monitoring of bone density is necessary in this trial.
Mortality/morbidity in preclinical trials
Mortality/sacrifice due to morbidity occurred in CByB6F1 non-transgenic mice and in Wistar 
Han rats. Clinical signs preceding morbidity were similar in both rodent species and included 
respiratory changes (rapid, shallow, and/or labored breathing), decreased motor activity, 
ruffled fur, hunched or prostrate posture, eye changes (squinting, discharge) and/or 
hypothermia. One humane sacrifice due to overt neurotoxicity was done in one dog of the 
3-day escalation trial. For details see the current version of the IB [c03536505]. 
Risk mitigation and monitoring: Data of previous trial 1371-0001 indicate good safety and 
tolerability of BI 894416 at all investigated doses (single oral doses up to 70 mg). The dose of 
BI 894416 given in this trial is equivalent to or lower than doses given previously to healthy 
subjects. That means, BI 894416 plasma exposures that are expected in this trial are in the 
range measured previously in trial 1371-0001 and that were associated with good safety and 
tolerability. Moreover, subjects will be in-house at the trial site, under close medical 
observation for 48 h after administration of BI 894416. Vital signs and ECGs will be 
measured during the trial, and subjects will be instructed to report AEs spontaneously and 
will be asked, at time points defined in the Flow Chart for AEs. In case of AEs in need of 
treatment, the investigator can authorize symptomatic therapy. In those cases, subjects will be 
treated as necessary and, if required, kept under supervision at the trial site, or transferred to 
another hospital, until all medical evaluation results have returned to an acceptable level.

In dog toxicology trials, acute adverse neurological effects, such as tremor and movement 
disorder assessed as dyskinesia (paresis/rigidity), were observed at high exposures (see IB 
[c03536505]). One dog was euthanized due to overt neurotoxicity in 3-day escalation trial at 
90 mg/kg/day. In dose escalation trial in dogs with assessment of neurotoxicity [n00245394], 
all clinical signs of neurotoxicity were reversible with cessation of dosing. No structural 
changes were observed in histopathology. Peripheral nerve conduction velocity and 
electroencephalogram were unchanged. No specific mechanism causing the neurological
effects in dogs has been elucidated. Therefore, it has not been determined whether the 
neurological changes are species specific; however, external expert review considered this is 
most likely a channelopathy specific to dog and not likely to occur in man (see IB
[c03536505]). 
Risk mitigation and monitoring: Subjects with neurological disorder or medical history of 
relevant neurological disorder are excluded from trial participation (see 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 the neurological examination will be 
excluded from trial participation (see Section 3.3.3). If necessary according to the 
investigator, 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 indicate that BI 894416 is not mutagenic or clastogenic. In the 2-
week repeat dose range finding trial 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. 
Therefore, there is a theoretical risk of a sub therapeutic exposure to BI 894416, or its 
metabolites, for a woman of child bearing potential (WOCBP) via the semen of a trial
subject. Developmental and reproductive trials have not yet been conducted. Therefore, the 
effect of sub therapeutic concentrations of BI 894416, or its metabolites, with regards to 
embryofetal development has not been explored so far. 
Risk mitigation: In order to address the risk of exposing an WOCBP 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
Phototoxicity potential of BI 894416 was measured in the open-lid Neutral Red Uptake test.
There was no indication of phototoxicity by BI 894416. Subjects will be advised to avoid 
direct exposure to sun and UV light during the entire trial (see Section 4.2.2.2). Further 
protective measures would not be necessary given the low phototoxic potential of BI 894416
(see IB [c03536505]).

Potential effects on QT interval
Preclinical trials suggested no proarrhythmic potential or cardiovascular liability with 
BI 894416. However, statistical results of first-in-man trial 1371-0001 suggested a 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% confidence interval (CI) was 10.5 ms). 
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 20), and subjects with a 
history of additional risk factors for Torsade de Pointes arrhythmia (Section 3.3.3, exclusion 
criterion 21) are excluded from trial participation. Moreover, subjects will be in-house under 
close observation for 48 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 1371-0003 due to potential effects on QT interval are 
considered minimal.
Liver toxicity
Although rare, a potential for drug-induced liver injury (DILI) is under constant surveillance 
by the sponsor. 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.
Overall assessment
1.4.3
BI 894416 is a highly specific SYK inhibitor that has been adequately characterised in pre-
clinical trials. 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 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 subjects (see IB [c03536505]).
BI 894416 plasma exposures in the current trial are expected to be within plasma exposure 
values that were observed in previous first-in-man trial 1371-0001 and SRD and MRD trial in 
mild asthma patients 1371-0008 and that were associated with good safety and tolerability.
Considering the medical need for treatment of uncontrolled severe persistent asthma and the 
potential advantage of a highly specific SYK, the sponsor considers that the benefit of this 
trial outweighs the potential risks.

The groups will be dosed consecutively in ascending order of the doses, and a time interval of 
at least 7 d will be maintained between the last drug administration to subjects in the previous 
dose group (dose group N) and the first drug administration to subjects in the subsequent 
dose group (dose group N+1). The decision to treat the next dose group will be based upon 
safety and tolerability of all the preceding dose groups. The next dose group will only be 
treated if, in the opinion of the investigator (or authorised deputy, Sub Investigator), and 
Clinical trial leader (CTL), no safety concerns have arisen in the preceding dose groups, i.e. 
no dose-limiting events occurred, and if none of the pre-specified trial-specific stopping 
criteria have been met (refer to Section 3.3.4).
A documented safety review must take place prior to each dose escalation. Furthermore, an 
unscheduled safety review meeting can be requested anytime for any reasonable cause by the 
Principal Investigator, or an authorised deputy, Sub Investigator, or the sponsor of the trial,
e.g. in case of any unforeseen adverse events. Dose escalation will only be permitted if no 
safety concerns exist in the opinion of the Principal Investigator (or an authorised deputy,  
Sub Investigator) and the CTL.
Although no formal Safety Review meeting will take place within a given dose group, safety 
will be continuously monitored during this trial, and an individual will only be dosed in the 
absence of any safety concern, i.e. no dose-limiting events occurred, and if none of the pre-
specified trial-specific stopping criteria have been met (refer to Section 3.3.4).
At minimum, data from 4 subjects on active drug need to be available for escalation to a 
higher dose. The minimum data set for review consists of the following:

AEs in the current and preceding dose groups up to at least 7 d post dosing including 
clinically relevant findings from ancillary safety testing listed below (Note: AEs may 
be ongoing at the time of Safety Reviews and AE information may be subject to 
change prior to Database Lock)

Results from 12-lead ECG in the current and preceding dose groups up to at least 3 d
post dosing

Vital signs in the current and preceding dose groups up to at least 3 d post dosing.

Clinical laboratory tests in the current and preceding dose groups up to at least 7 d
post dosing

Review of criteria for stopping subject treatment as per Section 3.3.4.1

The decision to escalate the dose will be made jointly by the Principal Investigator, or an 
authorised deputy, Sub Investigator, and the CTL after in-depth analysis of all available 
safety data, especially SAEs, AEs, and out-of-range laboratory results that are considered 
clinically significant by the investigator. Dose escalation will only be permitted if no safety 
concerns exist neither in the opinion of the Principal Investigator (or an authorised deputy, 
Sub Investigator) and the CTL. 
Safety Reviews can be conducted face-to-face or by video/telephone conference. The CTL is 
responsible for the organisation and minutes of the reviews. Minutes will be signed off by the 
Principal Investigator (or an authorised deputy, Sub Investigator) and CTL, and will be filed 
in the investigator site file (ISF) and trial master file (TMF). 
An overview of all relevant trial activities is provided in the Flow Chart. For visit schedules 
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(S)
For single -rising dose trials, the sequential rising dose design described in Section 3.1 is 
viewed favourably under the provision not to expose the subjects to undue risks, since the 
main trial objective is to investigate safety and tolerability of BI 894416.
Single-blind conditions regarding the subject’s treatment (active or placebo) are maintained 
within each dose group. However, subjects and investigators will be aware of the dose of the 
drug administered. The disadvantage of this trial design is a possible observer bias with 
regard to the dose-dependent effects; in addition, the sequential dosing of groups could 
potentially result in time-related effects. However, as such effects are expected to be small 
relative to the differences between the doses in the broad range investigated, unbiased 
comparisons between treatments can still be expected.
It is standard in single rising dose trials involving healthy subjects to include a placebo group 
to control for safety and tolerability of the trial medication. Each dose group consists of 8 
subjects, with 6 on active treatment, and 2 on placebo. For data analysis purposes, the 
placebo control group will include all subjects that were treated with placebo, regardless of 
the groups they were treated. Six subjects per active treatment group are generally considered 
to be sufficient for the exploratory evaluation of pharmacokinetics.
For this trial, 25 mg has been selected as the minimum dose, which may be required to 
achieve therapeutic systemic exposure to BI 894416. However, higher doses might still be 
well tolerated while providing a larger magnitude of therapeutic effects. Finally, even if the 
therapeutic dose is determined to be as low as 25 mg, higher than therapeutic doses are 
typically explored in Phase I trials to provide a safety margin for following trials e.g., drug-
drug-interaction trials, trials with patients with impaired excretion function, etc., where 
substantial increases in exposure may be seen.
Also, 70 mg has been selected as the maximum dose, a dose that is expected to be high 
enough to obtain exposure in the therapeutic range. The human exposure cap was a Cmax
gMean value of 5,233 nmol/L, AUC0-24 gMean value of 36,150 nmol·h/L, AUC0-24 the upper 
limit of 95% prediction interval of 63,000 nmol·h/L. The exposure cap of AUC0-24 gMean 
corresponded to 3-fold below exposure at the dog NOAEL and 7-fold below the lowest

exposure in dogs where neurologic effects were observed (for more details, please see the 
current version of the Investigator’s Brochure (IB) [c3536505]). Cmax gMean, AUC gMean 
and the upper limit of 95% prediction interval value are predicted to be below the exposure 
cap (Table 3.2: 1); therefore, single administration of 70 mg are considered safe.

For trial restrictions, refer to Section 4.2.2.
Withdrawal of subjects from treatment or assessments
3.3.4
Subjects may discontinue trial treatment, or withdraw consent to trial participation as a whole 
(‘withdrawal of consent’), with very different implications; please see sections 3.3.4.1 and 
3.3.4.2 below.
If a subject is removed from, or withdraws from, the trial prior to the first administration of 
trial medication, the data of this subject will not be entered in the case report form (CRF) and 
will not be reported in the clinical trial report (CTR). If a subject is removed from, or 
withdraws from, the trial after the first administration of trial medication, this will be 
documented and the reason for discontinuation must be recorded in the CRF; in addition, the 
data will be included in the CRF and will be reported in the CTR.
At the time of discontinuation, a complete end of trial examination will be performed, if 
possible, and the information will be recorded in the CRF. If the discontinuation occurs

before the end of the REP (see Section 1.2.2), the discontinued subject should, if possible, be 
questioned for AEs and concomitant therapies at, or after, the end of the REP in order to 
ensure collection of AEs and concomitant therapies throughout the REP, if not contrary to 
any consent withdrawal of the subject.
Discontinuation of trial treatment
3.3.4.1
An individual subject will be removed from the trial if:
1. The subject wants to discontinue trial treatment or trial participation , without the need to 
justify the decision
2. The subject needs to take concomitant medication that interferes with the investigational 
medicinal product or other trial treatment
3. The subject can no longer able to participate trial for other medical reasons, such as 
surgery, adverse events (AE)s, or diseases
4. The subject has an elevation of AST and/or ALT ≥3-fold upper limit of normal (ULN)
and an elevation of total bilirubin ≥2-fold ULN, as measured in the same blood sample,
and/or needs to be followed up according to the DILI checklist provided in the ISF
In addition to these criteria, the investigator may discontinue subjects at any time based on 
his or her clinical judgment.
A subject can also be removed from the trial if eligibility criteria are being violated or if the 
subject fails to comply with the protocol (for instance, by non-adherence to dietary rules, or 
non-attendance at trial assessments).
Withdrawal of consent to trial participation
3.3.4.2
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.
Discontinuation of the trial by the sponsor
3.3.4.3
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. Dose escalation will be terminated if more

Addition to this, dose escalation will be stopped if at least 2 subjects on active treatment at 
one dose level have relevant individual QT prolongations, i.e. a QTc increase greater than 60 
ms from baseline in connection with an absolute QT or QTc greater than 500 ms, as
confirmed by a repeat ECG recording.
The investigator/trial site will be reimbursed for reasonable expenses incurred in case of trial 
termination, except if item 3 applies.
Replacement of subjects
3.3.5
If some subjects do not complete the trial, the CTL, together with the Trial 
Pharmacokineticist and the Trial Statistician, are to decide if and how many subjects will be 
replaced. A replacement subject will be assigned a unique trial subject number, and will be 
assigned to the same treatment as the subject he replaces.

Selection of doses in the trial and dose modification
4.1.2
The dose range of BI 894416 for this trial was selected on the basis of the data obtained in the 
first-in-man SRD trials 1371-0001 and 1371-0008. So far, single doses up to 70 mg in 
healthy subjects and single doses up to 170 mg in asthma patients in fasting status was well 
tolerated.
Method of assigning subjects to treatment groups
4.1.3
Prior to the screening visit, subjects will be contacted in writing and informed about the 
planned visit dates. The subjects willing to participate will be recruited to dose groups 
according to their temporal availability. As soon as enough subjects are allocated to 1 of the 3 
dose groups, the following subjects will be allocated to one of the other dose groups and so

on until the dose groups are completed. Therefore, the allocation of subjects to dose groups is 
not influenced by trial personnel, but only by the subjects’ temporal availability. Because the 
trial is conducted on healthy subjects from a homogenous population, relevant imbalances 
between the dose groups are not expected. 
Subjects will be assigned to treatments (active treatment or placebo) prior to the first 
administration of trial medication. For this purpose, the randomisation list will be provided to 
the trial site in advance. Numbers of the randomization list will be allocated to subjects by the 
method ‘first come first served’. Subjects are then assigned to treatment 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.
Drug assignment and administration of doses for each subject
4.1.4
The treatments to be evaluated are outlined in Table 4.1.4: 1 below. The number of tablets for 
placebo corresponds to the number of tablets in the corresponding dose level.

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. 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. 
During the first 4 h after drug administration, the subjects are not allowed to lie down, i.e. no 
declination of the upper body of more than 45 degrees from upright posture except for 
medical examination, or to sleep.
Subjects will be kept under close medical surveillance until 48 h after dosing.
For restrictions with regard to diet, see Section 4.2.2.2.

Blinding and procedures for unblinding
4.1.5
Blinding
4.1.5.1
The trial is designed single-blind. The treatments administered (active or placebo) will be 
blinded to subjects, but will be known to the investigators (outcome assessors). Only the 
current dose level will be known to the subjects due to the rising dose design.
A single–blind design is considered acceptable, because the potential bias in this type of trial
seems to be low and, according to trial procedures, it is assured that the investigator's 
knowledge of the next treatment does not influence the decision to enter a subject. 
All trial data will be handled open label. This means that trial functions of the sponsor are 
unblinded, including clinical monitor, data manager, statistician, bioanalyst, 
pharmacokineticist, pharmacometrician, drug metabolism scientist, as well as dedicated 
personnel of the trial site. 
Within the central ECG lab, the staff involved with interval measurements will be blinded 
with respect to the treatment and also with regard to the recording date and time, as well as to 
the planned time points of the ECGs. The interval measurements for a given subject will be 
performed in a random and blinded sequence by a single technician.
If an interim safety analysis of ECG data is required, a part of the staff of the central ECG lab 
may be unblinded. This part of the staff will be strictly separated from the blinded staff 
members who will be involved with ECG interval measurements and assessments of ECGs.
Access to the randomisation schedule will be controlled and documented.
Unblinding and breaking the code
4.1.5.2
As this trial will be conducted single blind, subjects’ treatment assignments will be known to 
investigators. Therefore, no emergency envelopes will be provided.
Packaging, labelling, and re-supply
4.1.6
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 on packaging and for the description of the label, refer to the ISF.
The telephone number of the sponsor, as well as the name, address, and telephone number of 
the trial site are provided in the subject information form. Examples of the labels will be 
available in the ISF.
No re-supply is planned.
Storage conditions
4.1.7
Drug supplies will be kept in their original packaging and in a secure limited access storage 
area in accordance with the recommended (labelled) storage conditions. If necessary, a 
temperature log must be maintained to make certain that the drug supplies are stored at the 
correct temperature. If the storage conditions are found to be outside the specified range, the

Clinical Trial Manager (CTM), as provided in the list of contacts, is to be contacted 
immediately.
Drug accountability
4.1.8
The investigator, or a designee, will receive the investigational drugs from the sponsor when 
the following requirements are fulfilled:

Approval of the clinical trial protocol by the Institutional Review Board (IRB)

Availability of a signed and dated clinical trial contract between the sponsor and the 
investigational site

Approval/notification from the regulatory authority,  e.g. competent authority (CA)

Availability of the curriculum vitae of the Principal Investigator

Availability of a signed and dated clinical trial protocol  
Only authorised personnel documented in the form 'Trial Staff List' may dispense medication 
to trial subjects. The trial medication must be administered in the manner specified in the 
CTP. 
The investigator, or designee, must maintain records of the product’s delivery to the trial site, 
the inventory at the site, the use by each subject, and the disposal of unused products.These 
records will include dates, quantities, batch/serial numbers, expiry ('use-by') dates, and the 
unique code numbers assigned to the investigational medicinal product and trial subjects. The 
investigator, or designee, will maintain records adequately documenting that the subjects 
were provided the doses specified by the CTP and will reconcile all investigational medicinal 
products received from the sponsor. At the time of disposal of remaining trial medication, the 
investigator or designee must verify that no investigational medicinal product remains  in the 
investigator’s possession.
All unused trial medication will be disposed locally by the trial site upon written 
authorisation of the CTM. Receipt, usage, and disposal of trial medication must be 
documented on the appropriate forms. Account must be given for any discrepancies.
4.2
OTHER TREATMENTS, EMERGENCY  PROCEDURES,
RESTRICTIONS
Other treatments and emergency procedures
4.2.1
There are no special emergency procedures to be followed. No additional treatment is 
planned. However, if adverse events require treatment, the investigator can employ
symptomatic therapy. In those cases, subjects will be treated as necessary and, if required, 
kept under supervision at the trial site, or transferred to another hospital, until all results of 
medical evaluations are acceptable.

Restrictions
4.2.2
Restrictions regarding concomitant treatment
4.2.2.1
In principle, no concomitant therapy is allowed. All concomitant, or rescue therapies, will be 
recorded, including time of intake on trial days, on the appropriate pages of the CRF.
Acetylsalicylic acid, or other drugs that may inhibit platelet aggregation or coagulation,
should be avoided during the entire trial. If necessary, acetaminophen may be given 
occasionally, if required to treat an adverse event require.
Drugs that may increase exposure of BI 894416 should be avoided during the entire trial. 
Based on in vitro data, CYP3A is involved in the metabolism of BI 894416. In addition, BI 
894416 is substrate of P-glycoprotein in vitro. Data from the drug-drug interaction trial 1371-
0004 (see Section 1.2.1) indicate that inhibition of CYP3A and P-glycoprotein may cause 
mild increases of BI 894416 plasma concentrations. Therefore administration of CYP3A and 
P-glycoprotein inhibitors should be avoided during the entire trial.
BI 894416 is also a substrate of organic cation transporter 2 (OCT2). It is not excluded that 
inhibition of OCT2 could increase BI 894416 plasma exposure. Therefore administration of 
inhibitors of OCT2 should be avoided during the entire trial.
Restrictions on diet and life style
4.2.2.2
While admitted to the trial site, the subjects will be instructed not to consume any foods or 
drinks other than those provided by the staff. Standardised meals will be served at the times
indicated in the Flow Chart. No food is allowed for at least 10 h before and 4 h after trial 
medication intake
One h before drug intake until 4 h after trial medication intake, fluid intake is restricted to the 
water administered with the trial medication, and an additional 240 mL of water served at 2 h 
and 4 h post-dose (mandatory for all subjects). From 4 h after drug intake on Day 1 until 24 h 
post-dose, fluid intake is restricted to 3 L.
Alcoholic beverages, grapefruits, Seville oranges (sour or bitter oranges), as well as their 
juices, dietary supplements, and products containing St. John's wort (Hypericum perforatum) 
are not permitted from 7 d before the first administration of trial medication until after the last 
PK sample of each trial period is collected.
Poppy seed containing products should not be consumed starting 4 d before first 
investigational medicinal product administration until last PK sampling of the trial.
Methylxanthine-containing drinks or foods, such as coffee, tea, cola, energy drinks, or 
chocolate, are not allowed from 10 h before administration of trial medication until 24 h after 
administration of trial medication.
Smoking is not allowed during the trial.
Excessive physical activity, such as competitive sport, should be avoided from 7 d before the 
first administration of trial medication until the end of trial examination.

may be repeated at any time during the trial at the discretion of an investigator or designee. 
The results will not be included in the CTR.
The laboratory tests listed in Tables 5.2.3: 1 and 5.2.3: 2 will be performed at the local 
laboratory of the trial site or/and at a CRO designated by the sponsor. Laboratory data will be 
transmitted electronically from the site to BI.

5.2.4
12-lead resting ECG
5.2.4.1
Recording
Twelve-lead resting ECGs (I, II, III, aVR, aVL, aVF, V1 - V6) will be recorded using a 
computerised electrocardiograph at the time points given in the Flow Chart. Precise electrode 
placement will be performed according to the method of 
and
,
modified by 
 and 
, i.e. 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 trial.
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 10 s after subjects have rested for at least 5 min in a supine 
position. ECG recording will always precede all other trial procedures scheduled for the same 
time, except for blood drawing from an intravenous cannula that is already in place, to avoid 
compromising ECG quality.
ECGs will be recorded as single ECGs or as triplicate ECGs, i.e. three single ECGs recorded 
within 180 s, as indicated in the Flow Chart.
ECGs may be repeated for quality reasons due to, for instance, alternating current artefacts, 
muscle movements, or electrode dislocation. For repetition within triplicate ECGs, the time 
window of 180 s applies as well. The repeat ECGs are assigned to the respective scheduled 
time point.
Additional (unscheduled) ECGs may be collected by the investigator for safety reasons. 
These ECGs are assigned to the prior scheduled time point in the Sponsor’s database.
Storage
All ECGs will be stored electronically in the System provided by 
.
Data transfer
All triplicate ECGs will be transferred electronically to the central ECG laboratory 
 
 for evaluation.

In case of ECGs repeated due to quality reasons, only the repeated ECG recordings will be 
transferred to the central ECG lab, whereas the initially recorded ECGs will be discarded. 
Unscheduled ECGs, i.e. those taken for safety reasons, will be transferred to the central ECG 
lab, but will not be included into the statistical analysis of interval lengths.
Data transfer from the central ECG lab to the sponsor is described in a document that is filed 
in the TMF.
Evaluation
a) Central ECG lab
Central ECG lab evaluation will be performed (during the trial and/or after the trial) for 
first ECG of triplicate ECGs at every time point. For baseline, all three ECGs of the 
triplicate ECG at Day 1 pre-dose will be evaluated. This will include the determination of 
cardiac QRS-axis, as assessed by the ECG machine’s algorithm, as well as the intervals 
RR, PR, QRS, and QT measured semi-automatically. Heart rate (HR) and the QT interval 
corrected for HR, i.e. QTcF and QTcB, will be determined by the sponsor (see trial 
statistical analysis plan [TSAP] for details).
All semi-automatic interval measurements in one subject will be performed on the same 
lead. The intervals will be measured from four cardiac cycles (beats) in lead II. If lead II 
shows a flat T wave, or is not measurable for any reason, lead V5 will be used. If lead V5
is not measurable, then lead I will be used. The lead actually used will be reported in the 
CTR. For automatic interval measurements no lead will be provided
For blinding arrangements see Section 4.1.5.1. No more than two blinded readers will 
evaluate all ECGs of the trial. ECGs from a particular subject should be evaluated by a 
single reader. For quality assurance and control of the measurements, all ECGs of a 
subject will be subsequently reviewed by the ECG technician’s supervisor, or his/her 
designee, to assess the overall variance of the measured intervals, to detect accidental 
switching of leads and/or false subject assignments of the ECGs. After quality control, the 
fiducial point markings will be reviewed by the cardiologist assigned to the trial.
Evaluation of ECGs will comply with the ICH E14 guidance document and supplements 
[R07-4722, R16-0366] as well as the FDA requirements for annotated digital ECGs [R09-
4830].
b) Trial site 
All local ECGs will be evaluated by the investigator or a designee.
For the inclusion, or exclusion, (see Section 3.3) of a subject and for the assessment of 
cardiac safety during the trial, the QT and QTcB values generated by the computerised 
ECG system, or their manual corrections by the investigators, will be used. In doubtful 
cases, ECGs may be sent upfront, i.e. prior to the regular data transfer, for cardiologic 
assessment by the central lab. In this case, these centrally measured results would 
overrule any other results obtained.

Abnormal findings, irrespective of whether they originate from central or local evaluation, 
will be reported as AEs (during the trial) or baseline conditions (at screening) if judged 
clinically relevant by the investigator.
Any ECG abnormalities will be monitored carefully and, if necessary, the subject will be 
removed from the trial and will receive the appropriate medical treatment.
Continuous ECG monitoring
5.2.4.2
Cardiac rhythm, including heart rate, will be monitored by means of continuous 3-lead ECG 
recording for at least 15 min before drug administration, for baseline assessment, and for 4 h 
following drug administration. This continuous ECG monitoring supports the early detection 
of adverse events, such as clinically relevant bradycardia, tachycardia, or arrhythmia, at the 
trial site. Beyond this clinical evaluation at the trial site, no further data collection or analyses 
are performed based on continuous ECG monitoring.
ECG data from continuous ECG recording will not be transferred to the clinical trial database 
and will be evaluated by the investigator or a designee. Abnormal findings during continuous 
ECG recording will be recorded as AEs, if judged clinically relevant by the Investigator.
Other safety parameters
5.2.5
Neurological examination
5.2.5.1
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.

Assessment of adverse events
5.2.6
Definitions of adverse events
5.2.6.1
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, medical 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. Adverse events deemed serious for any other 
reason are important medical events that, based upon appropriate medical judgment,  
jeopardise the patient and may require medical or surgical intervention to prevent one 
of the other outcomes listed in the above. 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
An AE that possibly leads to disability will be ‘deemed serious for any other reason’ and 
reported as an SAE.

AEs considered ‘Always Serious’
5.2.6.1.3
Cancers of new histology and exacerbations of existing cancer must be classified as a serious 
events 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 meet the criteria of an SAE as defined 
above.
The latest list of ‘Always Serious AEs’ can be found in the electronic data capture (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, e.g. 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 investigational medicinal product
treatment continues or remains unchanged
Adverse event collection and reporting
5.2.6.2
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 subjects, 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 new 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 that are relevant for the 
reported SAE or AESI, on the BI SAE form via fax within 24 h to the sponsor’s unique entry 
point; the 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 AEs and SAEs, including those persisting after the individual subject’s end of trial, must 
be followed up until they have resolved, have been assessed as ‘chronic’ or ‘stable’, or no 
further information can be obtained.

Pregnancy
5.2.6.2.4
Once a male subject has been enrolled in the clinical trial and has taken trial medication, and 
if a partner of the male subject becomes pregnant, the investigator must report any drug 
exposure during pregnancy in this partner 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 completed. If there is an SAE and/or AESI associated with the pregnancy, an SAE 
form must be completed in addition

DRUG CONCENTRATION MEASUREMENTS AND 
PHARMACOKINETICS
Assessment of pharmacokinetics
5.3.1
Date and clock times of drug administration and pharmacokinetic sampling will be recorded
in Source data and in the CRFs.
Exact times of plasma sampling will be documented in the eCRFs by the medical personnel. 
The actual sampling times will be used for determination of pharmacokinetic parameters.
PK sampling times and periods may be adapted during the trial based on information 
obtained during trial conduct (e.g. as a result of preliminary PK data), including addition of 
samples and visits, as long as the total blood volume taken per subject does not exceed 
approximately 500 mL. Such changes would be implemented via non-substantial CTP 
Amendments.
Methods of sample collection
5.3.2
Blood sampling for pharmacokinetic analysis
5.3.2.1
For quantification of BI 894416 concentrations in plasma, 3.0 mL of blood will be drawn 
from an antecubital or forearm vein into an K2EDTA (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.
Two plasma aliquots each having at least 0.5 mL will be obtained and stored in an upright 
position at approximately -20°C or below at the trial site until shipment on dry ice to the

analytical laboratory. Details on sample handling, processing and shipments are described in 
the lab manual.
At a minimum, the sample tube labels should list BI trial number, subject number, visit, and 
planned sampling time. Further information such as matrix and analyte may also be provided. 
After completion of the trial, the plasma samples may be used for further methodological 
investigations (e.g., for stability testing or assessment of metabolites). However, only data 
related to the analyte and/or its metabolite(s) including anti-drug antibodies (if applicable) 
will be generated by these additional investigations. The trial samples will be discarded after 
completion of the additional investigations, but not later than 5 years after the CTR is 
archived.
Urine sampling for pharmacokinetic analysis
5.3.2.2
A blank urine sample will be collected before administration of trial medication (within 3 h 
before drug dosing) and two 0.5 mL aliquots will be retained to check for analytical 
interference by concomitant or rescue medication.
All urine voided during the sampling intervals indicated in the Flow Chart will be collected in 
urine containers and stored at room temperature. Subjects are told to empty their bladders at 
the end of each sampling interval. Details on sample handling, processing and shipments are 
described in the lab manual.
At a minimum, the sample tube labels should list BI trial number, subject number, visit, and 
planned collection time. Further information, such as matrix and analyte may also be 
provided.
Two urine aliquots each having at least 0.5 mL will be obtained and stored in an upright 
position at approximately -20°C or below at the trial site until shipment on dry ice to the 
analytical laboratory. Details on sample handling, processing and shipments are described in 
the lab manual.
The second aliquot will be transferred after the bioanalyst has acknowledged safe arrival of 
the first aliquot. At the analytical laboratory, the urine samples will be stored at 
approximately -20°C or below until analysis.
After completion of the trial, the urine samples may be used for further methodological 
investigations (e.g., for stability testing or assessment of metabolites). However, only data 
related to the analyte and/or its metabolite(s) will be generated by these additional 
investigations. The trial samples will be discarded after completion of the additional 
investigations but not later than 5 years after the CTR has been archived.

OTHER ASSESSMENTS
Pharmacogenomic evaluation
5.6.1
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 from each subject at Day -1. 
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.
5.7
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 2.1.3, 
2.2.2.2, and 5.3 are generally used assessments of drug exposure. 
Due to neurologic effects observed in dog trials, 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.
Trial measurements and assessments scheduled to occur ‘before’ trial medication 
administration at Day 1 are to be performed and completed within a 2 h-period prior to the 
investigational medicinal product administration (including blank values for PK). A blank 
urine sample for PK will be collected within 3 h before drug administration.
The acceptable deviation from the scheduled time for vital signs and ECG will be ± 10 min 
for the first 4 h after investigational medicinal product administration and ± 30 min 
thereafter. For laboratory test, the acceptable deviation is ± 30 min.
If several activities are scheduled at the same time point in the Flow chart, meal shoud be the 
last activity. Furthermore, if several measurements including venipuncture are scheduled for 
the same time, venipuncture should be the last of the measurements due to its inconvenience 
to the subject and possible influence on physiological parameters.
The acceptable deviation from the scheduled time for neurological tests is ± 45 min on Day 1 
and ± 90 min for other days.
For planned individual plasma concentration sampling times and urine collection intervals,
refer to the Flow Chart. While these nominal times should be adhered to as closely as 
possible, the actual sampling times will be recorded and used for the determination of 
pharmacokinetic parameters.
If a subject misses an appointment, it will be rescheduled if possible. The relevance of 
measurements outside the permitted time windows will be assessed no later than at the Report 
Planning Meeting.
6.2
DETAILS OF TRIAL PROCEDURES AT SELECTED VISITS
Screening period
6.2.1
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 trial.
For information regarding laboratory tests (including drug and virus screening), ECG, vital
signs, medical examination and neurological examination, refer to Sections 5.2.1 to 5.2.5. 
Genotyping will be performed (for details, see Section 5.6.1).
Treatment period
6.2.2
Each subject will receive one dose of trial medication (BI 894416 or placebo) at Visit 2.

Trial medication will be taken orally by each subject under direct supervision of the 
investigator or 
designee. Details on treatments and procedures of administration are 
described in Section 4.1.4.
Trial participants will be admitted to the trial site in the evening of Day -1 and kept under 
close medical surveillance for at least 48 h following drug administration. The subjects will 
then be allowed to leave the trial site, after formal assessment and confirmation of their 
fitness by the investigator or
 designee. On all other trial days, subjects will be treated in 
an ambulatory fashion.
For details on time points and procedures for collection of plasma and urine 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.
Follow-up period and trial completion
6.2.3
For AE assessment, laboratory tests, recording of ECG and vital signs, medical 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 End of Trial 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 End of Trial Visit must be 
followed until they have resolved, have been sufficiently characterised, or no further 
information can be obtained. 
If a subject discontinues from the trial, the subject will be followed until the investigator, or 
sub-investigator, is convinced of the subject’s safety. If follow-up is not possible or comes to 
an end, follow-up should be formally completed after discussion with the sponsor. If a subject 
stops attending trial assessments, the investigator should assess the subject’s status as 
comprehensively as possible and the well-being of the subject should be monitored. 
However, if the subject withdraws from the trial, it is the subject’s choice whether or not to 
participate in further assessments; he cannot be compelled.

STATISTICAL METHODS AND DETERMINATION OF
SAMPLE SIZE
7.1
STATISTICAL DESIGN – MODEL
The primary objectives of this trial is to investigate the safety and tolerability of BI 894416
by using descriptive statistics for all endpoints  comparing active dose groups to placebo.
The primary endpoint is defined in Section 2.1.2. Inferential statistics is not planned (as 
explained in section 7.2)
Secondary objectives are the exploration of PK of BI 894416 endpoints as specified in 
section 2.1.3 by descriptive statistics.
7.2
NULL AND ALTERNATIVE HYPOTHESES
Safety and tolerability of the different dose groups of BI 894416 are to be determined on the 
basis of the investigated parameters in comparison to placebo. It is not planned to test any 
statistical hypotheses. Instead, they will be described in their entirety and evaluated by 
descriptive statistical methods.
Any confidence intervals computed are to be interpreted in the perspective of the exploratory 
character of the trial; i.e., confidence intervals are considered as interval estimates for effects.
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 investigational medicinal product. The treatment 
assignment will be determined based on the first treatment the subjects received. 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 not excluded due to a 
protocol violation 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 specified in the TSAP, 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 will be calculated according to BI 
internal standard operating procedure (SOP). Noncompartmental pharmacokinetic parameters 
will be calculated based on actual sampling times using a validated pharmacokinetic software 
(e.g., Phoenix® WinNonlin®).
Plasma and urine concentration data and parameters of a subject will be included in the 
statistical PK analyses if they are not flagged for exclusion due to a protocol violation 
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 violations may be

Incorrect trial medication taken, i.e. the subject received at least one dose of trial 
medication the subject was not assigned to

Incorrect dose of trial medication taken

Use of restricted medications
Plasma and urine 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 PK disposition curve.
Plasma/urine 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.
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 as in the bioanalytical report (that is 
to the same number of decimal places provided in the bioanalytical report). 
Primary endpoint analyses
7.3.1
The primary endpoint as specified in Section 2.1.2 will be derived according to BI standards. 
The analysis will be based on the treated set (TS) and will be descriptive in nature.
Secondary endpoint analyses
7.3.2
Primary analyses
The secondary endpoints (refer to Section 2.1.3) will be analysed descriptively. Analyses will 
be performed for the parent drug.

Dose proportionality will be explored via graphical checks and if applicable via the power 
model stated below. The analysis will be performed for the pharmacokinetic endpoints 
AUC0-∞/Cmax specified in Section 2.1.3.
The power model describes the functional relationship between the dose level and PK 
endpoint on the log scale via
 =  log (xkm) = μ +   β ∙ log (Dk) +  ekm ,
where 
ykm
logarithm of response (PK parameter) measured on subject m receiving dose k,
xkm
response (PK parameter) measured on subject m receiving dose k,
μ
the overall mean,
β
slope parameter of linear regression line,
D
level of dose k, k=1,…,3,
ekm
the random error associated with the mth subject who was administered dose k 
(e~(0, ) iid).
The slope parameter β together with its two-sided 90% confidence interval will be estimated. 
Additionally, the r-fold change  ! together with its 90% CI will be derived.
As some small doses at the beginning and/or some doses at the upper end might not 
contribute to the linear relationship between dose and PK, dose proportionality over the entire 
dose range investigated might not be shown. In that case an attempt will be made to identify a 
subrange of at least 3 consecutive doses where dose proportionality can be concluded.
Safety analyses
7.3.4
Safety will be assessed as defined by the endpoints listed in Section 2.1.2 and 2.2.2 based on 
the treated set (TS). Safety analyses will be descriptive in nature and will be based on BI 
standards. 
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. The placebo group in the safety evaluation 
will consist of all subjects treated with placebo, regardless of the dose group in which they 
were treated. The test treatment groups will be compared to the placebo group in a descriptive

way. Tabulations of frequencies/proportions will be used for the evaluation of categorical 
(qualitative) data, and tabulations of descriptive statistics will be used to analyse continuous 
(quantitative) data.
Measurements (such as ECGs, 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 intake of trial medication will be 
assigned to the screening period, those between the trial medication intake and the individual 
subject’s end of REP (see Section 1.2.1) will be assigned to the treatment period. 
Events occurring after the REP but prior to trial termination date will be assigned to ’follow-
up’. 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 
database lock will be reported to Pharmacovigilance only and will not be captured in the trial 
database.
Additionally, further treatment intervals (called analysing treatments) may be defined in the 
TSAP in order to provide summary statistics for other than above periods, such as combined 
treatments, on-treatment totals, or periods without treatment effects (such as screening and 
post-trial 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 possibly clinically significant values 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. 
The ECG variables QT, HR, QTcF, QTcB, PR, QRS, and RR obtained from the centralised 
evaluation of 12-lead ECG recordings will be the basis for the derivation of quantitative and 
categorical ECG endpoints. These endpoints and their analyses will be described in the 
TSAP.
Pharmacokinetic - pharmacodynamic analysis
7.3.5
No analysis of the relationship between pharmacokinetic and pharmacodynamic parameters is 
planned for this trial.
7.4
INTERIM ANALYSES
No interim analysis is planned.

HANDLING OF MISSING DATA
Safety
7.5.1
It is not planned to impute missing values for safety parameters.
Pharmacokinetics
7.5.2
Handling of missing PK data will be performed according to the BI internal SOP.
PK parameters that cannot be reasonably calculated based on the available drug 
concentration-time data will not be imputed.
7.6
RANDOMISATION
The first 4 subjects per dose level will not be randomised to maintain a treatment sequence of 
active-placebo-active-active due to safety reasons. The remaining 4 subjects of each dose 
level will be randomised in a 3:1 ratio, which reflects the ratio of subjects receiving active 
drug to placebo.
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 include a total of 24 subjects in this trial. The planned sample size is not based 
on a power calculation. The size of 8 subjects per dose group (6 on active treatment, and 2 on 
placebo) is commonly used in single-rising dose trials of the present type and is in general 
considered as sufficient for the exploratory evaluation of single dose safety and 
pharmacokinetics [R95-0013].

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.
Source documents
8.3.1
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:
