Criteria for safety:
(1) Single rising dose part under fasting conditions
Primary endpoint to assess safety and tolerability of BI 705564 is the number 
[N (%)] of subjects with drug-related adverse events.
Further criteria of interest: Adverse events (AEs) including clinically relevant 
findings from the physical examination, safety laboratory tests, 12-lead 
electrocardiogram (ECG), continuous ECG monitoring, vital signs (blood 
pressure [BP], pulse rate [PR]).
(2) Food effect part
Further criteria of interest: AEs including clinically relevant findings from the 
physical examination, safety laboratory tests, 12-lead electrocardiogram (ECG), 
vital signs (blood pressure [BP], pulse rate [PR]).
(3) Single rising dose part under fed conditions
Primary endpoint to assess safety and tolerability of BI 705564 is the number 
[N (%)] of subjects with drug-related adverse events.
Further criteria of interest: Adverse events (AEs) including clinically relevant 
findings from the physical examination, safety laboratory tests, 12-lead 
electrocardiogram (ECG), continuous ECG monitoring, vital signs (blood 
pressure [BP], pulse rate [PR]).
Statistical methods:
(1) Single rising dose part under fasting conditions
Descriptive statistics will be calculated for all endpoints.
Dose proportionality of BI 705564 will be explored using a regression model. A 
95% confidence interval (CI) for the slope will be computed.
(2) Food effect part
Relative bioavailability will be estimated by the ratios (tablet fed/tablet fasting) 
of the geometric means for the primary and secondary endpoints. Additionally, 
their two-sided 90% confidence intervals (CIs) will be provided. This method 
corresponds to the two one-sided t-tests procedure, each at the 5% significance 
level. Since the main focus is on estimation and not testing, an acceptance range 
was not specified. The statistical model will be an ANOVA on the logarithmic 
scale including effects for ‘sequence’, ‘subjects nested within sequences’, 
‘period’ and ‘treatment’. CIs will be calculated based on the residual error from 
ANOVA. Descriptive statistics will be calculated for all endpoints.
(3) Single rising dose part under fed conditions
Descriptive statistics will be calculated for all endpoints.
Dose proportionality of BI 705564 will be explored using a regression model. A 
95% confidence interval (CI) for the slope will be computed.

RATIONALE, OBJECTIVES, AND BENEFIT - RISK 
ASSESSMENT
2.1
RATIONALE FOR PERFORMING THE TRIAL
 
 
Healthy male subjects will be recruited for this study. They provide a relatively stable 
physiological, biochemical and hormonal basis for studying drug effects, they show no 
disease-related variation and they are not taking regular concomitant medications.
In the single rising dose parts, within each dose group, all actively treated individuals will 
receive the same BI 705564 dose. The next higher dose will only be administered to the next 
group, if the treatment in the preceding dose group was safe and showed acceptable 
tolerability.
In the food effect part, BI 705564 will be administered to subjects in a randomized two-way-
crossover fashion to understand the effect of food on relative bioavailability and to support 
upcoming clinical studies in respect to better trial designs.
2.1.1
Starting Dose
An estimation was made on the basis of the US FDA Guidance for Industry ‘Estimating the
Maximum Recommended Safe Starting Dose in Initial Clinical Trials for Therapeutics in
Healthy Volunteers’ [R06-1037]:
 
 
 
It is stated in the FDA Guidance that ‘a species might be considered an inappropriate toxicity
model for a given drug, if the dose-limiting toxicity in that species was concluded to be of
limited value for human risk assessment, based on historical comparisons of toxicities in the
animal species to those in humans across a therapeutic class (i.e., the dose-limiting toxicity is
species-specific). In this case, data from that species should not be used to derive the HED.’

2.1.2
Maximum Dose and Dose Range
 
 
 
 
 
 
Therefore: (1) Systemic exposure of BI 705564 (Cmax, AUC0-24) will be closely monitored 
throughout the study and used to guide dose escalation. (2) A maximum allowable exposure 
is prospectively defined.

In conclusion, the maximum dose in this first-in-man/ single rising dose study will be limited 
by an exposure threshold (group gMean values) of
 
 whichever is reached first. With the exception of escalation from Dose Group 1 to 
Dose Group 2, the decision for dose escalation at each dose level will be guided by the results 
of PK interim analysis at each dose level and, if necessary, model based estimations. For dose 
escalation from Dose Group 1 to Dose Group 2, availability of interim pharmacokinetic data 
is not required.

2.1.4
Food effect part
Since a 
 of BI 705564 at higher doses might be improved by the application of 
food, the effect of food on the relative bioavailability of BI 705564, as tablet formulation will 
be investigated. The food effect may be dose dependent. 
 
 
 
 
 
2.1.5
Conclusion
The safe starting dose in this study is determined 
 This dose is not expected to 
trigger any relevant or unacceptable biological activities.
 
In the single rising dose part under fasting conditions, the following dose escalation scheme 
is planned: 
 
 
Each dose escalation step in the single rising dose part under fasting conditions will be 
guided by interim PK measurements and projected exposure levels.
 
With global amendment No 4, a single rising dose part under fed conditions is added.
 
 
Each dose escalation step in the single rising dose part 
under fed conditions will be guided by interim PK measurements and projected exposure 
levels.
2.2
TRIAL OBJECTIVES
The primary objective of the single rising dose parts under fasting and under fed conditions is 
to investigate safety and tolerability of BI 705564 in healthy male subjects following oral 
administration of single rising doses. Secondary objectives are the exploration of

pharmacokinetics (PK) including dose proportionality, and pharmacodynamics (PD) of 
BI 705564 after single rising doses.
The objective of the food effect part is to explore the relative bioavailability of BI 705564 
tablets under fed and fasting conditions following the oral administration of single doses.
A description of the endpoints to be determined, and the observations along with specific 
information as how to collect the data, is provided in Section 5.
2.3
BENEFIT - RISK ASSESSMENT
Participation in this study is without any (therapeutic) benefit for healthy subjects. Their 
participation in the study, however, is of major importance to the development of this 
compound which is expected to be superior over other BTK inhibitors being developed in 
non-oncological indications due to its higher selectivity. Subjects participating in this trial are 
exposed to the risks of study procedures and those, related to the exposure of trial medication.
2.3.1
Procedure-related risks
The use of an indwelling venous catheter for the purpose of blood sampling may be 
accompanied by mild bruising and also, in rare cases, by transient inflammation of the wall of 
the vein. In addition, in rare cases, a nerve might be injured while inserting the venous 
catheter, potentially resulting in paresthesia, reduced sensibility, and/or pain for an indefinite 
period. Same risks apply to venipuncture for blood sampling.
The total volume of blood withdrawn during the entire study per subject will not exceed the 
volume of a normal blood donation, i.e. 500 mL. No health-related risk to healthy subjects is 
expected from this blood withdrawal.
2.3.2
Drug-related risks and safety measures
Factors of risk may derive from particular knowledge or the lack thereof, regarding (1) the 
mode of action, (2) the nature of the target, (3) the relevance of animal models and/or (4) 
findings in non-clinical safety studies.
2.3.2.1
Mode of action
BTK is a well characterized target with known functions in the immune signalling pathways 
of B cells and myeloid cell lineages (see Section 1.1). First clinical experience with the 
approved BTK inhibitor ibrutinib is available (see Sections 1.1 and 1.2.5). In addition, a
‘human model’ with loss of function mutations of the BTK gene is known as syndrome XLA.
The immunodeficiency of XLA patients seems to be limited to the decreased levels of 
circulating antibodies. The resulting (predominant) bacterial infections should be well 
controlled by the application of antibiotics and gammaglobulin substitution, if necessary
[R17-0404].
Ibrutinib treatment in patients with hematologic malignancies is associated with adverse
events including hypertension, thrombocytopenia, and GI complaints (abdominal pain,

nausea, diarrhea, and vomiting). As these are not usual features of XLA, they may be related 
to off-target inhibition by ibrutinib of other enzymes besides BTK. Atrial fibrillation has been 
reported in patients receiving ibrutinib. The causal relationship of this finding to ibrutinib is 
not clear. The majority of affected patients had pre-existing cardiovascular disease, and most 
cases resolved quickly [R17-0124]. Other investigational BTK inhibitors (GDC-0853 and
CC-292) were generally well tolerated in Phase 1 and Phase 2 clinical trials in healthy 
volunteers and in patients with rheumatoid arthritis. Serious infections, hypertension, 
thrombocytopenia, and atrial fibrillation were not reported [R17-0165, R17-0166]. All these 
conditions can be well monitored and are accessible to established therapies.

will be the minimum time between treatments in the food effect part (wash-out period) and 
from last administration of study drug until the end of trial examination in all study parts.
2.3.2.2
Nature of the target
The BTK protein is intra-cellular expressed in myeloid and lymphoid cell lines, 
predominantly in the immune system (bone marrow, appendix, lymph nodes, tonsils, and 
spleen), as well as in the lung. [R17-0406] Although on-target effects are unlikely to occur 
after a single dose of BI 705564, they might resemble those seen in XLA patients: Inhibition 
of B-cell differentiation which may manifest as a transient decrease of peripheral B-cell 
numbers, transient decrease of immunglobuline levels and unlikely bacterial infections. Main 
safety measures performed throughout the study will be therefore: (1) Exclusion of subjects 
with a repeated decrease of CD19+ B cell count at screening. (2) Monitoring of white blood 
cell counts and particularly CD19+ B cell counts, as well as immunoglobulin levels for at 
least 10 days after drug administration. (3) Close monitoring for adverse events including 
symptoms of infections. (4) In case of infections, appropriate clinical evaluation and, if 
necessary, adequate treatment thereof.
‘Down-stream’ effects of BTK inhibition are well characterized (see Section 1.2.1). How 
these effects may vary in different populations, e.g. healthy subjects versus diseased patients, 
young versus elderly, different patient populations, etc., is not known. Also, no information 
on BTK polymorphisms in healthy individuals and their potential influence on 
pharmacodynamics effects of BI 705564 or other BTK inhibitors are available.
2.3.2.3
Relevance of animal species and models
Animal models and assays, used during the pharmacological (mice) and toxicological (rats, 
dogs) assessment of BI 705564 were similar, at large, to those used for the development and 
submission of ibrutinib. As such, their relevance for humans was acknowledged by regulatory 
authorities [R17-0403]. For further information, see current version of IB [c12104992-02].

In the current trial, HP-ß-cyclodextrin is the main ingredient of the solvent for oral solution. 
 
2.3.2.6
Drug induced liver injury
Although rare, a potential for drug-induced liver injury (DILI) is under constant surveillance 
by sponsors and regulators. Therefore, this trial requires timely detection, evaluation, and 
follow-up of laboratory alterations in selected liver laboratory parameters to ensure subjects´ 
safety. See also Section 5.2.2.1.
2.3.2.7
Risk minimization (safety precautions and stopping rules)
The following precautionary measures will be taken in this study in order to minimize the 
risk for healthy volunteers:
∀
Careful starting dose selection, as described in Section 2.1.1.
∀
In the single rising dose part under fasting conditions, decreasing escalation factors
with increasing doses, as described in Section 2.1.3 were chosen. In the single rising 
dose part under fed conditions, escalation factors of 2 were chosen, based on 
experience gained during the trial.
∀
In the single rising dose parts, for safety reasons, each dose group of 8 subjects (6 on 
active, 2 on placebo) will be divided into two cohorts of 4 subjects each (3 on active, 
1 on placebo). The first cohort of each dose group will be dosed in a fixed sequence 
manner (active - placebo - active - active) and each drug administration will be 
separated by at least 60 minutes between the first 3 subjects. This design ensures that 
between first and second active dose of each dose level there is a time interval of at 
least 2 hours. For orally administered drugs, this is usually a sufficient time frame to 
observe acute effects and to obtain a significant proportion of the systemic exposure. 
If BI 705564 is safe and shows acceptable tolerability during these initial 
administrations, the remaining subjects of this dose group can be dosed as close as 
10 minutes apart.
∀
For each dose group, the 2 cohorts will be separated by at least 46 hours (between the 
1st subject of each cohort) which is expected to cover the period of highest risk/ peak 
effect.
∀
Interim measurements of BI 705564 plasma levels will be performed. The expected 
gMean systemic exposure (Cmax, AUC) in the next higher dose group will be 
estimated based on current and preceding doses using a dose proportionality approach

or model-based estimations, as applicable. The next higher dose level will only be 
administered, if estimated group gMean values of Cmax and AUC do not exceed the 
maximum acceptable human exposure
whichever is reached first. This should provide a safety margin to the NOAEL of >20 
(see Table 1.2.3.2: 1). In the single rising dose part under fasting conditions, for dose 
escalation from Dose Group 1 to Dose Group 2, availability of interim PK data is not 
required.
∀
If one dose level is safe and shows acceptable tolerability, and if no stopping criterion 
is met (see Section 3.3.4.2), the next higher dose may be given, keeping a minimum
dosing time interval of 10 days between the first subject of the current dose group and 
the first subject of the following dose group.
∀
Extensive standard safety laboratory measurements including serum electrolytes, 
serum amylase and lipase, differential white blood counts, as well as CD19+ B cell 
and platelet counts will be performed before and after study drug administration (see
Flow Charts and Section 5.2.3).
∀
A thorough ECG and heart rate monitoring will be performed, including continuous 
ECG measurements over 4 hours post dose to cover the anticipated period of highest 
drug exposure, and additional repeated single 12-lead ECGs.
∀
Prior to each dose escalation, a documented safety review will be performed by the
Principal Investigator (or an authorized deputy) and the Trial Clinical Monitor (or an
authorized deputy). For details, see Section 3.1.
∀
In the food effect part, the 10 mg dose will be tested first and thereafter the 40 mg 
dose will be tested*. The 10 mg dose will only be given, if, in the single rising dose 
part, doses of up to 40 mg are safe and of acceptable tolerability. The 40 mg dose will 
only be given, if, in the single rising dose part, doses of up to 160 mg are safe and of 
acceptable tolerability and, if, based on available preliminary PK data, the systemic 
exposure (group gMean Cmax, AUC0-24) is not expected to exceed the maximal group 
gMean values reached in the single rising dose part*.
* Global Amendment No 4: In the food effect part, the 40 mg dose is not tested.
∀
Subjects will be confined under close observation for at least 24 hours after drug 
administration at the trial site and will be discharged only after a formal assessment 
and confirmation of fitness by an investigator or qualified designee. During in-house 
confinement subjects will be under medical observation and thoroughly monitored for 
both, expected and unexpected adverse events.

OVERALL ASSESSMENT AND CONCLUSION
BI 705564 is an inhibitor of BTK to be developed for the treatment of LN, SLE and 
rheumatoid arthritis. Clinical experience has been gained with another BTK inhibitor, 
ibrutinib, which was approved for the treatment of hematologic malignancies (chronic

lymphocytic leukaemia, mantle cell lymphoma, and Waldenström’s macroglobulinemia).
Treatment with ibrutinib in patients with hematologic malignancies is associated with adverse 
events including hypertension, thrombocytopenia, and GI complaints which may be related to 
off-target effects. In contrast, BI 705564 is considered to be a more selective BTK inhibitor
and may have a more favourable safety profile.
Considering preclinical data of BI 705564, the well characterised target structure and its 
physiologic role in B cell differentiation and function, and taking into account the safety 
measures described above, participation in this single dose regimen does not represent an 
undue risk to healthy subjects.
Inhibition of BTK in patients with LN and SLE is expected to block the stimulation of 
autoantibody-producing B cells, and the release of inflammatory cytokines from monocytes 
and macrophages. By diminishing these harmful effects, BI 705564 may slow or halt disease 
progression. Considering the medical need for a better LN/ SLE treatment and taking into 
account the potential advantage of a highly selective BTK inhibitor, the expected benefit of 
this trial is likely to outweigh the potential risks and justifies exposure of healthy volunteers.

DESCRIPTION OF DESIGN AND TRIAL POPULATION
Global Amendment No 4 – major changes in Section 3:
Originally, the study was planned to consist of two study parts: (1) SRD part under fasting
conditions consisting of 8 dose groups (1 to 160 mg) à 8 volunteers (64 volunteers in total) 
and (2) food effect part investigating the effect of a high-fat, high-calorie breakfast on doses 
of 10 mg and 40 mg in 12 volunteers each, i.e. in 24 volunteers total. 
Data obtained during the trial indicate that no relevant increase of exposure was to be
expected with dose groups 120 mg and 160 mg in the SRD part under fasting conditions. 
Therefore, the two highest dose groups of the SRD part under fasting conditions (120 mg and 
160 mg) are not dosed. Data of the food effect part 10 mg indicate that relative bioavailability 
of BI 705564 tablet may be increased by food. The food effect part 40 mg is not dosed. 
Instead, a third study part is added. A SRD part under fed conditions is added to the study and
is designed to investigate single rising oral doses of BI 705564 after a high-fat, high-calorie 
breakfast. It is planned to apply BI 705564 to 4 dose groups à 8 volunteers per group (32 
volunteers in total) with the possibility to add up to 2 interim dose groups in the SRD part 
under fed conditions (see Section 3.1, “Single rising dose part under fed conditions”).
See Appendix 11 for details.
3.1
OVERALL TRIAL DESIGN AND PLAN
A total of 92 healthy male subjects is planned to participate in the trial, thereof 48 in the 
single rising dose part under fasting conditions, 12 in the food effect part, and 32 in the single 
rising dose part under fed conditions. Additional subjects may be entered in the single rising 
dose part under fed conditions (see below). Thus, the actual number of subjects may exceed 
92 but not 108 subjects entered.
Single rising dose part under fasting conditions
This part is designed single-blind, partially randomised, and placebo-controlled within 
parallel dose groups.
A total of 48 healthy male subjects is planned to participate in the single rising dose part
under fasting conditions, resulting in 6 sequential groups comprising 8 subjects each. 
Within each dose group, 6 subjects will receive the active drug and 2 will receive placebo. 
Only one dose is tested within each dose group. Dose groups will be treated consecutively in 
ascending order of doses. Each dose group will consist of 2 cohorts of 4 subjects each (3 on 
active drug and 1 on placebo).
On the first study day within each dose group, the first cohort will be treated in a single-blind 
manner in the following order: First subject (active) followed at least 1 hour later by the 
second subject (placebo) followed at least 1 hour later by the third subject (active) followed 
at least 10 minutes later by the fourth subject (active).

If BI 705564 treatment is safe and showed acceptable tolerability in the first cohort, subjects 
in the second cohort will be treated not earlier than 2 days later (at least 46 h between the 
1st subject of each cohort) in a single-blind, randomised manner. In the second cohort, a time 
interval of at least 10 minutes will be maintained between administrations of trial drug to the 
individual subjects.
A time interval of at least 10 days will be maintained between the first drug administration in 
the previous dose group and the first drug administration of the subsequent dose group. The 
dose groups to be evaluated are outlined in Table 3.1: 1 below.

The decision to proceed to the next dose group will be based upon the safety, tolerability and 
pharmacokinetic data of the preceding dose groups. The next dose will only be given, if, in 
the opinion of the investigator, no safety concerns arose in the preceding dose group (i.e. no 
dose-limiting events occurred) and, if none of the pre-specified trial-specific stopping criteria 
were met (see Section 3.3.4.2).
A documented Safety Review must take place prior to each dose escalation. Furthermore, an 
unscheduled safety review meeting can be requested at any time for any reasonable cause by 
the Principal Investigator (or an authorised deputy) or the sponsor of the study, e.g. because 
of any unforeseen adverse events, etc. Dose escalation will only be permitted, if no safety 
concerns exist in the opinion of the Principal Investigator (or an authorised deputy) and the 
Trial Clinical Monitor (or an authorised deputy).
The minimum data set for review consists of the following data:
∀
AEs in the current and preceding dose groups up to at least 48 h post dosing,
including clinically relevant findings from ancillary safety testing, as 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 and continuous ECG monitoring in the current and 
preceding dose groups up to at least 48 h post dosing.

organization and minutes of the reviews. Minutes will be signed off by the Principal 
Investigator (or an authorised deputy) and filed in the ISF and TMF.
The investigator and/ or the sponsor should stop dose escalation in case the safety evaluation 
leads to concerns that would not allow higher dosing.
An overview of all relevant trial activities is provided in Flow Chart 1. For visit schedules 
and details of trial procedures at selected visits, see Sections 6.1 and 6.2, respectively.
Food effect part
This part will be performed as a randomised, open-label, two-way crossover trial part in 
healthy male subjects in order to compare the test treatment (T) to the reference treatment 
(R).
A 10 mg dose will be tested in a group of 12 subjects. For decision criteria see Section 
2.3.2.7.
The subjects will be randomly allocated to the two treatment sequences (T-R or R-T). The 
treatments will be one 10 mg tablet of BI 705564 in the fed state (T) and one 10 mg tablet of 
BI 705564 in the fasting state (R). For details, see Section 4.1.
There will be a washout period of at least 10 days between treatments.
An overview of all relevant trial activities is provided in Flow Chart 2. For visit schedule and 
details of trial procedures at selected visits, see Sections 6.1 and 6.2, respectively.
Single rising dose part under fed conditions
This part is designed single-blind, partially randomised, and placebo-controlled within 
parallel dose groups.
A total of 32 healthy male subjects is planned to participate in the single rising dose part
under fed conditions, resulting in 4 sequential groups comprising 8 subjects each. However, 
additional subjects may be entered to allow testing of additional doses on the basis of the 
experience gained during the conduct of the trial (e.g. preliminary PK data), provided that the 
planned and approved highest dose will not be exceeded. Thus, the actual number of subjects 
entered in the single rising dose part may exceed 32, but will not exceed 48 subjects entered. 
Such changes may be implemented via non-substantial CTP amendments.

DISCUSSION OF TRIAL DESIGN, INCLUDING THE CHOICE OF 
CONTROL GROUP(S)
Single rising dose parts under fasting and fed conditions
For single-rising dose trials, the design described in Section 3.1 is viewed favourable under 
the provision not to expose the subjects involved to undue risks since the main study 
objective is to investigate safety and tolerability of BI 705564.
With the rising dose design, single-blind conditions regarding the subject’s treatment (active 
or placebo) are maintained within each dose group. However, the current dose level will be 
known to subjects and investigators. The disadvantage of this trial design is a possible 
observer bias with regard to the dose-depending effects as well as time effects but it has the 
virtue of minimizing subject risk by sequentially studying ascending doses. As time-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 trials involving healthy volunteers to include a placebo group as control for 
the evaluation of safety, tolerability, and pharmacodynamics effects. Each dose group 
consists of 8 subjects with 6 on active treatment, and 2 on placebo. The placebo control group

includes all subjects of all dose groups treated with placebo. 6 subjects per active treatment 
group are in general considered as sufficient for the exploratory evaluation of 
pharmacokinetics.
Food effect part
For relative bioavailability trials, the crossover design is preferred due to its efficiency. Since 
each subject serves as his own control, the comparison between treatments is based on a 
comparison within subjects rather than between subjects. This trial design, therefore, removes 
inter-subject variability from the comparison between treatments [R94-1529].
Blinding is not possible because the treatments are distinguishable.
The open-label treatment is not expected to bias results.
3.3
SELECTION OF TRIAL POPULATION
It is planned that 48 healthy male subjects will enter the single rising dose part under fasting
conditions, that 12 healthy male subjects will enter the food effect part of the study, and that 
32 healthy male subjects will enter the single rising dose part under fed conditions (i.e., 92 
volunteers in total).
The actual number of subjects entered into the trial may exceed the total of 92 (all three trial 
parts together), if additional, intermediate doses within the approved dose range will be tested 
in the single rising dose part under fasting conditions (see Section 3.1). Subjects will be 
recruited from the volunteers' pool of the trial site.
Subjects that were entered and treated in the single rising dose part under fasting conditions
may be entered again in the food effect part, provided the time interval between the drug 
administration in the single rising dose part and the first drug administration in the food effect
part is more than 60 days. Subjects that were entered and treated in the single rising dose part 
under fasting conditions are not allowed to be entered in the single rising dose part under fed 
conditions.
Only male subjects will be included into the study because hitherto no data on reproductive 
toxicology are available.
A log of all subjects enrolled into the trial (i.e. having given informed consent) will be 
maintained in the ISF at the investigational site irrespective of whether they have been treated 
with investigational drug or not.
3.3.1
Main diagnosis for study entry 
The study will be performed in healthy subjects.
3.3.2
Inclusion criteria
Subjects will only be included into the trial, if they meet the following criteria:

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 study assessments).
If a subject is removed from or withdraws from the trial prior to first administration of trial 
medication, the data of this subject will not be entered in the case report form (CRF) or trial 
database and will not be reported in the clinical trial report (CTR). If a subject is removed 
from or withdraws from the trial after first administration of trial medication, this will be 
documented and the reason for discontinuation must be recorded in the CRF. In this case, the 
data will be included in the CRF/ trial database and will be reported in the CTR. At the time 
of discontinuation, a complete end of trial examination will be performed, if possible, and the 
information will be recorded in the CRF.
3.3.4.2
Discontinuation of the trial by the sponsor
BI reserves the right to discontinue the trial overall or at a particular trial site at any time for 
any of the following reasons:
1. New toxicological findings or serious adverse events invalidate the earlier positive 
benefit-risk-assessment. More specifically, the trial will be terminated, if more than 50% 
of subjects show drug-related and clinically relevant adverse events of moderate or severe 
intensity or, if at least one drug-related serious adverse event is reported that is considered 
to be unacceptable.
2. The expected enrolment goals overall or at a particular trial site are not met.
3. Violation of GCP, or the CTP by a trial site or investigator, disturbing the appropriate 
conduct of the trial.
4. The sponsor decides to discontinue the further development of the investigational 
product.
5. Dose escalation will be stopped as soon as at least 2 subjects at one dose level on active 
drug shows relevant individual QT prolongation, i.e. a QTc increase of greater than 60 ms 
from baseline in connection with absolute QT or QTc greater than 500 ms which has been 
confirmed by a repeat ECG recording.
6. Dose escalation will be stopped, if the Cmax or AUC0-24 of at least 2 subjects of one dose 
group increases above the following exposure thresholds or, if the estimated gMean
exposure of the next dose group is expected 
 
 Estimation will be done based on preliminary pharmacokinetics results of 
preceding dose groups (see Section 7.3.5).
3.3.5
Replacement of subjects
In case there are less than 4 subjects on active drug per dose level in the single rising dose
parts under fasting or fed conditions or less than 9 subjects per dose level in the food effect 
part who do not complete the trial, the trial clinical monitor 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 study subject number, and will be 
assigned to the same treatment as the subject he replaces.

Method of assigning subjects to treatment groups
Prior to the screening visit, subjects will be contacted in writing and informed about the 
planned visit dates. Subjects willing to participate will be recruited to dose groups in the 
single rising dose- or food effect part according to their temporal availability. As soon as 
enough subjects have been allocated to 1 of the 12 dose cohorts (2 cohorts per dose group) in 
the single rising dose part under fasting conditions, the following subjects will be allocated to 
one of the other dose cohorts in the single rising dose part under fasting conditions. As soon 
as enough subjects have been allocated to 1 of the 8 dose cohorts (2 cohorts per dose group) 
in the single rising dose part under fed conditions, the following subjects will be allocated to 
one of the other dose cohorts in the single rising dose part under fed conditions. In the food 
effect part, there is only one dose group. Therefore, the allocation of subjects to dose cohorts 
or groups is not influenced by trial personnel, but only by the subjects’ temporal availability. 
As the study includes healthy subjects from a homogenous population, relevant imbalances 
between dose groups are not expected.
The randomisation list with study subject numbers and allocated treatments will be provided 
to the trial site in advance. The allocation of subjects to study subject numbers will be 
performed prior to the first administration of trial medication. For this purpose, the subjects 
will be allocated to a study subject number by drawing lots. Once a subject number has been 
assigned, it cannot be reassigned to any other subject.

performed following an overnight fast starting no later than 10 hours before scheduled 
dosing.
In the ‘fed’ treatment, a high-fat, high-calorie meal will be served 30 minutes before drug 
administration. The meal must be completely consumed prior to drug administration. The 
composition of the standard high-fat, high-calorie meal will be in compliance with the FDA 
guidance ‘Food-Effect Bioavailability and Fed Bioequivalence Studies’ [R03-2269] as 
detailed in Table 4.1.4: 3.

* Subjects receiving placebo are equally distributed across dose groups.
** For technical reasons related to drug packaging, numbers 9-11 cannot be attributed to dose groups in the 
SRD part under fed conditions.
The trial medication will be administered to the subjects, while in a sitting or standing 
position, as an oral dose together with about 240 mL of water under supervision of the 
investigating physician or an authorised designee. The so-called four-eye principle (two-
person rule) should be applied for administration of trial medication, if correct dosage cannot 
be ensured otherwise.
Subjects will be kept under close medical surveillance until at least 24 hours following drug 
administration. During the first 4 hours after drug administration, they are not allowed to 
sleep and will be confined to bed with a bed inclination angle of at least 45 degrees unless 
lower or supine position is required for trial-related measurements (e.g., recording of 12-lead 
ECG) or medical reasons (e.g., adverse events). For restrictions with regard to diet, see
Section 4.2.2.2.
Additional doses
Additional subjects may be entered to allow testing of additional doses on the basis of the 
experience gained during the conduct of the trial (e.g. preliminary PK data), provided that the 
planned and approved highest dose will not be exceeded (see Section 3.1). Such changes may 
be implemented via non-substantial CTP amendments.
Application of food
A high-fat, high-calorie meal will be served 30 minutes before drug administration. The meal 
must be completely consumed prior to drug administration. The composition of the standard 
high-fat, high-calorie meal will be in compliance with the FDA guidance ‘Food-Effect 
Bioavailability and Fed Bioequivalence Studies’ [R03-2269] as detailed in Table 4.1.4: 5.

Subjects will be kept under close medical surveillance until at least 24 hours following drug 
administration. During the first 4 hours after drug administration, they are not allowed to lie 
down (i.e. no declination of the upper body of more than 45 degrees from upright posture)
except, if required for trial-related measurements (e.g., recording of 12-lead ECG) or for 
medical reasons (e.g., adverse events). For restrictions with regard to diet see Section 4.2.2.2.
4.1.5
Blinding and procedures for unblinding
4.1.5.1
Blinding
The database of this trial will be handled open-label, because no bias with regard to data 
cleaning or safety measures is expected. This is considered acceptable because the potential 
for bias seems to be low and does not outweigh practical considerations.
Single rising dose parts under fasting and fed conditions
The treatments administered (active or placebo) will be single-blind (blinded to subjects 
only). However, the current dose level will be known to the subjects.
The bioanalyst or analytical laboratory and the trial pharmacokineticist may receive the 
randomisation codes of the single rising dose part prior to official unblinding to perform the 
preliminary PK analysis. He or she will treat the codes confidentially.
In addition, the drug metabolism scientist may receive the randomisation codes prior to 
official unblinding to perform metabolites in safety testing analysis (MIST). He or she will 
confirm in writing that the codes will be treated confidentially.
Within the ECG laboratory, the staff involved with interval measurements and assessments 
will be blinded with respect to the treatment within each dose level and also with regard to 
the recording date and time as well as the 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. No more than two different blinded readers will evaluate the ECGs of the 
study.

Food effect part
This part of the trial will be handled in an open fashion throughout (that is, during the 
conduct, including data cleaning and preparation of the analysis). This is considered 
acceptable because the potential for bias seems to be low and does not outweigh practical 
considerations.
4.1.5.2
Procedures for emergency unblinding
As this trial will be conducted single blinded (single rising dose parts under fasting and fed 
conditions) and open-label (food effect part), the treatment information will be known to the 
investigator. Therefore, no emergency envelopes will be provided.
4.1.6
Packaging, labelling, and re-supply
Drug supplies will be provided by the 
 
The clinical trial supply consists of containers holding the trial medication which are labelled

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 
local clinical monitor (as provided in the list of contacts) is to be immediately contacted.
4.1.8
Drug accountability
The investigator will receive the investigational drugs delivered by the sponsor when the 
following requirements are fulfilled:
∀
Approval of the trial protocol by the IRB / ethics committee.
∀
Approval/notification of the regulatory authority, e.g. competent authority.
∀
Availability of the curriculum vitae of the Principal Investigator.
∀
Availability of a signed and dated clinical trial protocol.
Only authorised personnel, as 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. All unused medication will be disposed locally by the trial site upon 
written authorisation by the clinical monitor. Receipt, usage and disposal must be 
documented on the respective forms. Account must be given for any discrepancies.
The investigator 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 products and trial subjects. The 
investigator will maintain records that document adequately that the subjects were provided 
the doses specified by the CTP, and that reconcile all investigational products received from 
the sponsor. At the time of disposal, the investigator must verify that no remaining supplies 
are in the investigator’s possession.

OTHER TREATMENTS, EMERGENCY PROCEDURES, 
RESTRICTIONS
4.2.1
Other treatments and emergency procedures
There are no special emergency procedures to be followed. No additional treatment is 
planned. However, in case of adverse events 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 a hospital until all medical 
evaluation results have returned to an acceptable level.
4.2.2
Restrictions
4.2.2.1
Restrictions regarding concomitant treatment
In principle, no concomitant therapy is allowed. All concomitant or rescue therapies will be 
recorded (including time of intake on study days) on the appropriate pages of the CRF.

Paracetamol and acetylsalicylic acid should be avoided. Ibuprofen should preferably be used 
for treatment of pain such as headache or toothache.
4.2.2.2
Restrictions on diet and life style
While admitted to the trial site the subjects are restricted from consuming any other foods or 
drinks than those provided by the staff. Standardised meals will be served at the time points 
described in the Flow Charts. No food is allowed for at least 4 hours after drug intake.
From 1 hour before drug intake until lunch, fluid intake is restricted to the milk served with 
breakfast (see Table 4.1.4: 3 and Table 4.1.4: 5), the water administered with the drug, and an 
additional 240 mL of water served at 2 hours and 4 hours post-dose (mandatory for all 
subjects).
From lunch until discharge from the study centre, liquid intake is restricted to additional 
3 litres.
Green tea, grapefruits, Seville oranges (sour or bitter oranges) and their juices, and dietary 
supplements and products including St. John's wort (Hypericum perforatum) are not 
permitted starting 7 days before administration of trial medication until after the last PK 
sample of each study period is collected.

medication until after the last PK sample of each study period is collected.
Smoking is not allowed during in-house confinement at the trial site.
Methylxanthine-containing drinks or foods (such as coffee, tea, cola, energy drinks, and 
chocolate) are not allowed from 10 hours before administration of trial medication until the 
end of the in-house period at the trial site.
Excessive physical activity (such as competitive sport) should be avoided starting 7 days 
before the first administration of trial medication until the end of trial examination.
Direct exposure to the sun or exposure to solarium radiation should be avoided during the 
entire study.
4.3
TREATMENT COMPLIANCE
Compliance will be assured by administration of all trial medication in the study centre under 
supervision of the investigating physician or a designee. The measured plasma concentrations 
and/or urinary excretion will provide additional confirmation of compliance.
Subjects who are non-compliant (for instance, who do not appear for scheduled visits or 
violate trial restrictions) may be removed from the trial and the CRF will be completed 
accordingly (for further procedures, please see Section 3.3.4.1).

5.2.2
Assessment of adverse events
5.2.2.1
Definitions of adverse events
Adverse event
An adverse event (AE) is defined as any untoward medical occurrence in a patient or clinical 
investigation subject administered a medicinal product and which does not necessarily have 
to have a causal relationship with this treatment.
An AE can therefore be any unfavourable and unintended sign (including an abnormal 
laboratory finding), symptom, or disease temporally associated with the use of a medicinal 
product, whether or not considered related to the medicinal product.
Adverse reaction
An adverse reaction is defined as a response to a medicinal product which is noxious and 
unintended. Response in this context means that a causal relationship between a medicinal 
product and an adverse event is at least a reasonable possibility. Adverse reactions may arise 
from use of the product within or outside the terms of the marketing authorisation or from 
occupational exposure. Conditions of use outside the marketing authorization include off-
label use, overdose, misuse, abuse and medication errors.
Serious adverse event
A serious adverse event (SAE) is defined as any AE which:
∀
Results in death,
∀
Is life-threatening, this 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 or prolongation of existing hospitalisation,
∀
Results in persistent or significant disability or incapacity,
∀
Is a congenital anomaly/birth defect, or
∀
Is to be deemed serious for any other reason if it is an important medical event when 
based upon appropriate medical judgment which may jeopardise the patient and may 
require medical or surgical intervention to prevent one of the other outcomes listed in 
the above definitions.
Medical and scientific judgement should be exercised in deciding whether other situations 
should be considered serious reactions, such as important medical events that might not be 
immediately life threatening or result in death or hospitalisation but might jeopardise the 
patient or might require intervention to prevent one of the other outcomes listed 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. Any suspected transmission via a medicinal product of 
an infectious agent is also considered a serious adverse reaction.

001-MCS-40-106-RD-11 (5.0) / Saved on: 25 Jun 2014
AEs considered ‘Always Serious’
In accordance with the European Medicines Agency initiative on Important Medical Events, 
BI has set up a list of further AEs which, by their nature, can always be considered to be 
‘serious’ even though they may not have met the criteria of an SAE as given above.
The latest list of ‘Always Serious AEs’ can be found in the RDC system, a remote 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.
Cancers of new histology and exacerbations of existing cancer must be reported as a serious 
event regardless of the duration between discontinuation of the drug and the occurrence of the 
cancer.
Adverse events of special interest (AESIs)
The term 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. AESI 
need to be reported to the sponsor’s Pharmacovigilance Department within the same 
timeframe that applies to SAE, please see above.
The following are considered as AESIs in this trial:
∀
Hepatic injury, as defined by the following alterations of hepatic laboratory 
parameters:
o
An elevation of AST and/or ALT ≥3-fold ULN combined with an elevation of
total bilirubin ≥2-fold ULN measured in the same blood sample, and/or
o
Marked peak aminotransferase (ALT, and/or AST) elevations ≥10 fold ULN
These lab findings constitute a hepatic injury alert and the patients showing these lab 
abnormalities need to be followed up according to the ‘DILI checklist’ provided in the 
ISF or RDC system. In case of clinical symptoms of hepatic injury (icterus, 
unexplained encephalopathy, unexplained coagulopathy, right upper quadrant 
abdominal pain, etc.) without lab results (ALT, AST, total bilirubin) available, the 
Investigator should make sure 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.
With the exception of DILI, no AESIs have been defined for this trial.
Intensity of AEs
The intensity of the AE should be judged based on the following:
Mild:
Awareness of sign(s) or symptom(s) that is/are easily tolerated.
Moderate:
Enough discomfort to cause interference with usual activity.
Severe:
Incapacitating or causing inability to work or to perform usual activities.

Causal relationship of AEs
The definition of an adverse reaction implies at least a reasonable possibility of a causal 
relationship between a suspected medicinal product and an adverse event. An adverse 
reaction, in contrast to an adverse event, is characterised by the fact that a causal relationship 
between a medicinal product and an occurrence is suspected.
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 diminished).
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 study drug treatment continues or remains 
unchanged.

5.2.2.2
Adverse event collection and reporting
AEs collection
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, 
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 Charts. 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 careful 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, and intensity of the event as 
well as 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 through the residual effect period (REP), 
until an individual subject’s end of trial:
o
All AEs (serious and non-serious) and all AESIs.
o
The only exception to this rule are AEs (serious and non-serious) and AESIs 
in Phase I trials in healthy volunteers, when subjects discontinue from the trial 
due to screening failures prior to administration of any trial medication. In 
these cases, the subjects’ data must be collected at trial site but will not be 
entered in the CRF or trial database and will not be reported in the CTR.
∀
After the individual subject’s end of trial:
o
The investigator does not need to actively monitor the subject for AEs but 
should only report relevant SAEs and relevant AESIs of which 
 may 
become aware of.

Single rising dose parts and food effect part
The REP for BI 705564, when measurable drug levels or PD effects are still likely to be 
present after the last administration, is not known for this first-in-human trial. Therefore, all 
AEs reported until the end of trial examination (last per protocol contact) will be considered 
on treatment; see Section 7.3.4. The follow-up period describes the period of time from the 
last administration of trial medication until the end of trial examination (last per protocol 
contact).
AE reporting to sponsor and timelines
The Investigator must report SAEs, AESIs, and non-serious AEs which are relevant for the 
reported SAE or AESI, on the BI SAE form via fax immediately (within 24 hours of 
awareness) to the sponsor’s unique entry point (country specific contact details will be 
provided in the ISF). The same timeline applies if follow-up information becomes available. 
In specific occasions the Investigator could inform the sponsor upfront via telephone. This 
does not replace the requirement to complete and fax the BI SAE form.
With receipt of any further information to these events, a follow-up SAE form has to be 
provided. For follow-up information the same rules and timeline apply as for initial 
information.
Information required
For each AE, the investigator should provide the information requested on the appropriate 
CRF pages and the BI SAE form (if applicable). The investigator should determine the causal 
relationship to the trial medication.
The following should also be recorded as an (S)AE in the CRF and on the SAE form (if 
applicable):
∀
Worsening of the underlying disease or of other pre-existing conditions.
∀
Changes in vital signs, ECG, physical examination and laboratory test results, if they 
are judged clinically relevant by the investigator.
If such abnormalities already pre-exist prior trial inclusion they will be considered as 
baseline conditions.

up until they have resolved, have been sufficiently characterised, or no further information 
can be obtained.

Assessment of safety laboratory parameters
For the assessment of laboratory parameters, blood and urine samples will be collected by the 
trial site at the time points indicated in the Flow Charts after the subjects have fasted for at 
least 10 h. Overnight fasting is not required at the discretion of the investigator or designee
for retests or drug screening. In the single rising dose part under fed conditions, fasting is not 
applicable to the post-dose safety laboratory on Day 1.
The parameters that will be determined are listed in Tables 5.2.3: 1 and 5.2.3: 2. Reference 
ranges will be provided in the ISF, Section 10.
Manual differential white blood cell count or urine sediment examinations will only be 
performed, if there is an abnormality in the automatic blood cell count or in the urinalysis,
respectively.

results will not be included in the CTR.
The laboratory tests listed in Table 5.2.3: 1 and 5.2.3: 2 will be performed at 
 
with the exception of 
the drug screening tests. These tests will be performed at the trial site using e.g. AccuSign®

Electrocardiogram
5.2.4.1
12-lead resting ECG
Twelve-lead resting ECGs (I, II, III, aVR, aVL, aVF, V1 - V6) will be recorded using a 
computerised electrocardiograph (CardioSoft EKG System, GE Medical Systems, Freiburg, 
Germany) at the time points given in the Flow Charts.
In order to achieve a stable heart rate at rest and to assure high quality recordings at 
comparable resting phases, all ECGs will be recorded for a 10-second duration after the 
subjects have rested for at least 5 minutes in a supine position. The site personnel will be 
instructed to assure a relaxed and quiet environment so that all subjects are at complete rest 
during the recordings. ECG assessment will always precede all other study procedures of the 
same time point (except blood drawing from an intravenous cannula which is already in 
place) to avoid impact of sampling on the ECG quality.
All ECGs will be stored electronically on the 
 
 Electrode placement will be performed according to the 
method of Wilson, Goldberger and Einthoven modified by Mason and Likar (hips and

shoulders instead of ankles and wrists). Precise electrode placement will be marked with an 
indelible mark on the skin to allow reproducible placement throughout the study.
All locally printed ECGs will be evaluated by the investigator or a designee.
ECGs may be repeated for quality reasons (like alternating current artefacts, muscle 
movements, electrode dislocation). For time points with triple ECGs, all three single ECGs 
will be repeated. For the repeats due to quality reasons, only the repeated ECG recordings 
will be sent to the central ECG lab, whereas the initially recorded ECGs will be discarded.
Additional (unscheduled) ECGs may be collected by the investigator for safety reasons. 
These ECGs are assigned to the prior scheduled time point. Unscheduled ECGs will not be 
included into the statistical analysis of interval lengths.
For the inclusion or exclusion (see Section 3.3) of a subject and for the assessment of cardiac 
safety during the study, the QT and QTcB values generated by the ECG machines or their 
manual corrections by the investigators will be used. In doubtful cases, ECGs may be sent 
upfront for centralised evaluation (see below). In this case, these centrally measured results 
would overrule any other results obtained.
Abnormal findings 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.
Single rising dose parts under fasting and fed conditions: Triple ECGs will be recorded (three 
single ECGs within 180 sec) at all time points in Visit 2. At Visits 1 and 4, single ECGs will 
be recorded.
Food effect part: It is planned that single ECGs will be recorded for all time points. However, 
the number of ECGs per time point may be increased to three ECGs based on preliminary 
ECG results obtained during the single rising dose part of the study.
Single rising dose parts only
In the single rising dose parts, a centralised evaluation (during study and/or post study) of all 
12-lead ECGs recorded at Visit 2 will be performed by an independent ECG laboratory. This 
analysis will include the determination of cardiac axis (automatically) as well as the intervals 
RR, PR, QRS and QT measured semi-automatically.
With the exception of the first triple ECG (used as baseline before the first drug 
administration), only the first of the three replicate ECGs at a single assessment time will be 
evaluated. The remaining second and third replicate ECGs will be stored for additional 
analyses if required, e.g. by authorities at a later time point.
For each QT interval, the RR interval preceding the QT will be measured to calculate the 
respective frequency corrected QTc intervals ‘QTcF’ according to Fridericia’s formula 
(QTcF = QT/ RR1/3) and ‘QTcB’ according to Bazett’s formula (QTcB = QT/ RR1/2). The 
QTcF correction will be used for evaluation and reporting. Abnormalities detected during 
centralised ECG evaluation will not necessarily qualify as AE. All 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, or if that lead is not measurable, then lead I will be used. The 
lead actually used will be reported in the CTR.
For blinding arrangements see Section 4.1.5.
Assessed ECGs will comply with the ICH E14 guidance document and supplements [R05-
2311, R13-0801, R13-4095] as well as the FDA requirements for annotated digital ECGs 
[R09-4830].
5.2.4.2
Continuous ECG monitoring
Cardiac rhythm (including heart rate) will be monitored by means of continuous 3-lead ECG 
recording for at least 15 minutes before (for baseline assessment) and 4 hours following drug 
administration using patient monitors (e.g. Carescape B450, GE Healthcare, Freiburg, 
Germany). Abnormal findings will be recorded as AEs if judged clinically relevant by the 
Investigator but no other data will be transferred to the database.
5.2.5
Assessment of other safety parameters
5.2.5.1
Vital signs
Systolic and diastolic blood pressures (BP) as well as pulse rate (PR) or heart rate (heart rate 
is considered to be equal to pulse rate) will be measured by a blood pressure monitor 
(Dinamap Pro 100, GE Medical Systems, Freiburg, Germany) at the times indicated in the 
Flow Charts, after subjects have rested for at least 5 minutes in a supine position. All 
recordings should be made using the same type of blood pressure recording instrument on the 
same arm if possible.
5.2.5.2
Medical examinations
At screening, the medical examination will include demographics including height and body 
weight, smoking and alcohol history, relevant medical history and concomitant therapy, 
review of inclusion and exclusion criteria, review of vital signs (BP, PR), 12-lead ECG, 
laboratory tests, and a physical examination. At the end of trial examination, it will include 
review of vital signs, 12-lead ECG, laboratory tests, and a physical examination.

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 and 
biomarkers in an appropriate way. The scheduled measurements will allow monitoring of
changes in vital signs, standard laboratory values, and ECG parameters that might occur as a 
result of administration of trial medication. The safety assessments are standard, are accepted 
for evaluation of safety and tolerability of an orally administered drug, and are widely used in 
clinical trials. The pharmacokinetic parameters and measurements outlined in Section 5.5 are 
generally used assessments of drug exposure. The biomarkers and measurements, outlined in 
Section 5.6, are of exploratory nature only.
5.5
DRUG CONCENTRATION MEASUREMENTS AND 
PHARMACOKINETICS
Date and clock time of drug administration and pharmacokinetic sampling will be recorded.
Exact time points of plasma sampling will be derived from the 
 
 and documented in the CRFs by the medical personnel or sent as electronic files 
to the trial data manager. 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. preliminary PK data) including addition of samples and 
visits as long as the total blood volume taken per subject does not exceed 500 mL. Such 
changes would be implemented via non-substantial CTP amendments.

Methods of sample collection
5.5.2.1
Plasma sampling for pharmacokinetic analysis
For quantification of BI 705564 plasma concentrations, 2.7 mL of blood will be taken from 
an antecubital or forearm vein into a K3-EDTA (tripotassium ethylenediaminetetraacetic 
acid)-anticoagulant blood drawing tube at the times indicated in the Flow Charts. Blood will 
be withdrawn by means of either an indwelling venous catheter or by venipuncture with a 
metal needle.
The EDTA-anticoagulated blood samples will be centrifuged for about 10 minutes at about 
2000 g to 4000 g and at 4 to 8 °C. Two plasma aliquots will be obtained and stored in 
polypropylene tubes. The first aliquot should contain at least 0.5 mL plasma. The process 
from blood collection until transfer of plasma aliquots into the freezer should be completed 
within 90 minutes, with interim storage of blood samples and aliquots in ice water or on ice
or cryoblocks. For each aliquot the time when the sample was placed in the freezer will be 
documented. Until transfer on dry ice to the analytical laboratory, the aliquots will be stored 
upright at about -20°C or below at the trial site. The second aliquot will be transferred to the 
analytical laboratory after the bioanalyst has acknowledged safe arrival of the first aliquot. At

the analytical laboratory the plasma samples will be stored at about -20°C or below until 
analysis.
At a minimum, the sample tube labels should list the following information: 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, assessment of metabolites. However, only data related 
to the analyte and/or its metabolite(s) including anti-drug antibodies (if applicable) will be 
generated by these additional investigations. The study samples will be discarded after 
completion of the additional investigations but not later than 5 years upon the final study 
report has been signed.

5.5.2.3
Urine sampling for pharmacokinetic analysis (single rising dose parts under 
fasting and fed conditions)
A blank urine sample will be collected before administration of trial medication (within the 
3 hours 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 Charts will be collected 
in 2 liters polyethylene (PE) containers and stored at room temperature. Subjects are told to 
empty their bladders at the end of each sampling interval.
 
The urine weight/volume for each collection interval will be documented (however, no 
correction for the specific gravity of urine is done, i.e. 1 liter is defined to be equal to 1 kg). 
Two 0.5 mL aliquots will be stored in polypropylene (PP) tubes for bioanalytical 
measurement. In case more than one collection container is used in an interval, the contents 
of all containers are to be mixed before aliquots are prepared. Mixing should be done by 
transferring the entire content of all collection containers into a single PE/PP or glass 
container, and stirring the mixed fractions for about 1 minute (manually or using a stir bar or 
other stirring device out of PE, PP, Teflon or glass).
At minimum, the sample tube labels should list at least the following information: BI trial 
number, subject number, visit, and planned collection time. Further information such as 
matrix and analyte may also be provided.
Until transfer on dry ice to the analytical laboratory, the urine samples will be stored at 
about -20°C or below at the trial site. The second aliquot will be transferred after the 
bioanalyst has acknowledged safe arrival of the first aliquot. At the analytical laboratory the 
plasma samples will be stored at about -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, assessment of metabolites. However, only data related 
to the analyte and/or its metabolite(s) will be generated by these additional investigations. 
The study samples will be discarded after completion of the additional investigations but not 
later than 5 years upon the final study report has been signed.

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 end of trial examination are given in Flow 
Chart 1 and Flow Chart 3 for the single rising dose part under fasting and fed conditions, 
respectively, and Flow Chart 2 for the food effect part.
Study measurements and assessments scheduled to occur ‘before’ trial medication 
administration on Day 1 are to be performed and completed within a 3 h-period prior to the 
trial drug administration (including blank values for PK and biomarkers).
Starting from 72 h post administration a deviation from the scheduled time for PK and 
biomarker sampling of ±70 min is acceptable. The biomarker samples planned time Day 6 
(single rising dose parts) may be taken on day 5 (up to 26 h earlier).
The acceptable deviation from the scheduled time for vital signs, ECG and laboratory tests 
will be ± 15 minutes for the first 4 hours after trial drug administration and ± 30 minutes
thereafter. Starting from 72 h post administration a deviation from the scheduled time for
vital signs, ECG and laboratory tests of ±70 min is acceptable.
If scheduled in the Flow Charts at the same time as a meal, blood sampling, vital signs and 
12-lead ECG recordings have to be done first. Furthermore, if several measurements 
including 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.
For planned individual plasma concentration sampling times and urine collection intervals,
see Flow Charts. While these nominal times should be adhered to as closely as possible, the 
actual sampling times will be recorded and used for determination of pharmacokinetic
parameter.
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.

Treatment periods
Single rising dose parts under fasting and fed conditions
Each subject will receive one dose of the respective trial medication (BI 705564 or placebo) 
at Visit 2.
Study participants will be admitted to the trial site in the morning of Day 1 and kept under 
close medical surveillance for at least 24 hours following drug administration. 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 study days, the study will be performed in an 
ambulatory fashion.
For details on time points and procedures for collection of plasma and urine samples for PK 
analysis, see Flow Chart 1, Flow Chart 3 and Section 5.5.2.
Safety measurements performed during the treatment period are specified in Section 5.2,
Flow Chart 1 and Flow Chart 3. For details on time points for all other trial procedures, refer 
to Flow Chart 1 and Flow Chart 3. AEs and concomitant therapy will be assessed 
continuously from screening until the end of trial examination.
Food effect part
Each subject is expected to participate in two treatment periods. The treatment periods will be 
separated by at least 10 days between drug administrations.
On Day 1 of each treatment period study participants will be admitted to the trial site and 
kept under close medical surveillance for at least 24 hours following drug administration.
Subjects will then be allowed to leave the trial site after formal assessment and confirmation 
of their fitness. On all other study days, the study will be performed in an ambulatory fashion.
For details on time points and procedures for collection of plasma samples for PK analysis, 
see Flow Chart 2 and Section 5.5.2.
Safety measurements performed during the treatment period are specified in Section 5.2 and 
Flow Chart 2. For details on time points for all other trial procedures, see Flow Chart 2. AEs 
and concomitant therapy will be assessed continuously from screening until the end of trial 
examination.
6.2.3
End of trial period
For AE assessment, laboratory tests, recording of ECG and vital signs, and physical 
examination during the end of trial period, see Sections 5.2.2 to 5.2.5.
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 judged 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 subject’s end of trial must be followed

The end of the trial as a whole is defined by the ‘last regular visit completed by last subject’ 
or ‘end date of the last open AE’ or ‘date of the last follow-up test’ or ‘date of an AE has 
been decided as sufficiently followed-up’, whichever is latest.

STATISTICAL METHODS AND DETERMINATION OF
SAMPLE SIZE
7.1
STATISTICAL DESIGN – MODEL
7.1.1
Objectives
Single rising dose parts under fasting and fed conditions
The primary objective of these parts of the trial is to investigate the safety and tolerability of 
BI 705564 by using descriptive statistics for all endpoints comparing active dose groups to 
placebo.
The primary endpoint is defined in Section 5.2.1. Inferential statistics is not planned (as 
explained in Section 7.2).
 
The secondary objective is the exploration of the pharmacokinetics (PK) and
pharmacodynamics (PD) of BI 705564. Endpoints as specified in 5.5.1 (for PK) and 5.7.1
(for PD) will be analysed by descriptive statistics. Secondary endpoints, as defined in 
Section 5.5.1.1, will be subjected to analysis of dose proportionality by use of the power 
model.
 
Food effect part
The primary objective of this part of the trial is to investigate a possible food effect, 
comparing the tablet formulation under fasting (Reference R) to that under fed conditions 
(Test, T) following oral administration. The trial is designed to allow an intra-subject 
comparison and will be evaluated statistically by use of an appropriate linear model.
The secondary objective is the evaluation and comparison of several pharmacokinetic 
parameters between treatments. They will be assessed by descriptive statistics.
The assessment of safety and tolerability will be an additional objective of this trial, and will 
be evaluated by descriptive statistics.
7.1.2
Endpoints
Single rising dose parts under fasting and fed conditions
Safety and tolerability will be determined on the basis of the parameters specified in 
Section 5.2.1. PK and PD endpoints are specified in Sections 5.5.1 (for PK) and 5.7.1 (for 
PD).
Food effect part
Food effect is to be determined on the basis of the primary and secondary pharmacokinetic 
endpoints (AUC0-tz, Cmax and AUC0-∞, see Section 5.5.1).

Safety and tolerability will be determined on the basis of the parameters specified in 
Section 5.2.1.
7.1.3
Model
Single rising dose parts under fasting and fed conditions
Endpoints will be analysed by descriptive statistics. Inferential statistics is not planned (as 
explained in Section 7.2).
Secondary endpoints, as defined in Section 5.5.1.1, will be subjected to analysis of dose 
proportionality by use of the power model.
Food effect part
The statistical model used for the analysis of primary and key secondary endpoints will be an 
ANOVA (analysis of variance) model on the logarithmic scale. This model will include 
effects accounting for the following sources of variation: ‘sequence’, ‘subjects within 
sequences’, ‘period’ and ‘treatment’. The effect ‘subjects within sequences’ will be 
considered as random, whereas the other effects will be considered as fixed. The model is 
described by the following equation:
yijkm = # + ∃i + sim + %j + &k + eijkm,
where
yijkm = logarithm of response (endpoint, see Section 7.1.2) measured on subject m in 
sequence i receiving treatment k in period j,
# = the overall mean,
∃i = the ith sequence effect, i = 1, 2,
sim = the effect associated with the mth subject in the ith sequence,
m = 1, 2, ..., ni
%j = the jth period effect, j = 1, 2,
&k = the kth treatment effect, k = 1, 2,
eijkm = the random error associated with the mth subject in sequence i who received
treatment k in period j.
7.2
NULL AND ALTERNATIVE HYPOTHESES

investigated parameters in comparison to placebo. It is not planned to test any statistical 
hypotheses with regard to these variables in a confirmatory sense. Instead, they will be 
described in their entirety and evaluated by descriptive statistical methods.
Confidence intervals will be computed and will have to be interpreted in the perspective of 
the exploratory character of the study, i.e. confidence intervals are considered as interval 
estimates for effects.
Food effect part
The food effect of the BI 705564 tablet will be estimated by the ratios of the gMeans 
(test/reference) for the primary and secondary PK endpoints. Additionally, their two-sided 
90% confidence intervals (CIs) will be provided. This method corresponds to the two one-
sided t-tests procedure, each at the 5% significance level. Since the main focus is on 
estimation and not testing, an acceptance range was not specified, that is, no hypothesis will 
be tested.
7.3
PLANNED ANALYSES
All individual data will be listed.
Adherence to the protocol (such as inclusion/exclusion criteria, times of measurement, 
compliance with intake of trial medication, treatment dispensing errors, prohibited 
concomitant medication, completeness and consistency of data) will be checked. Important 
protocol violations (IPVs) will be identified no later than in the Report Planning Meeting and 
provided in the TSAP.
7.3.1
Primary analyses
Single rising dose parts under fasting and fed conditions
Analysis of safety and tolerability is described in Section 7.3.4.
Food effect part
The pharmacokinetic endpoints listed in Section 5.5.1 will be calculated according to the BI 
Standard Operating Procedure (SOP) ‘Standards and processes for analyses performed within 
Clinical Pharmacokinetics/Pharmacodynamics’ [001-MCS-36-472].
Plasma concentration data and parameters of a subject will be included in the statistical 
pharmacokinetic (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.

∀
Incorrect trial medication taken, i.e. the subject received at least one dose of trial 
medication the subject was not assigned to.
∀
Incorrect dose of trial medication taken.
∀
Use of restricted medications.
Plasma concentrations and/or parameters of a subject will be considered as non-evaluable, if 
for example
∀
The subject experienced emesis that occurred at or before two times median tmax of 
the respective treatment (median tmax is to be determined excluding the subjects 
experiencing emesis).
∀
The subject experiences emesis at any time during the labelled dosing interval.
∀
A pre-dose concentration is >5% of the Cmax value of that subject.
∀
Missing samples/concentration data at important phases of PK disposition curve.
The PK parameter analysis set (PKS) includes all subjects in the Treated Set (TS) who 
provide at least one primary or secondary PK parameter that was not excluded according to 
the description above. 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. Point estimates of 
bioavailability, the ratios of the gMeans (test/ reference) for the primary and secondary
endpoints (see Sections 5.5.1.1 and 5.5.1.2), and their two-sided 90% confidence intervals 
(CIs) will be provided.
To this end, the PK endpoints will be log transformed (natural logarithm) prior to fitting the 
ANOVA model (see Section 7.1.3). For each endpoint, the difference between the expected 
means for log(T) - log(R) will be estimated by the difference in the corresponding adjusted 
means (LeastSquares Means), and a two-sided 90% confidence interval based on the 
t-distribution will be computed. These quantities will then be back-transformed to the original 
scale to provide the point estimate and 90% CIs for each endpoint.
7.3.2
Secondary analyses
Single rising dose parts under fasting and fed conditions
The secondary parameters (see Section 5.5.1) will be calculated according to the BI Standard 
Operating Procedure (SOP) ‘Standards and processes for analyses performed within Clinical 
Pharmacokinetics/Pharmacodynamics’ [001-MCS-36-472]. Analyses will be performed for 
BI 705564.
Plasma and urine concentration data and parameters of a subject will be included in the 
statistical pharmacokinetic (PK) analyses, if they are not flagged for exclusion due to a 
protocol 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.

For more information on relevant protocol violations and the definition of the PKS, see
Section 7.3.1. Excluded subjects will be listed with their individual plasma concentrations. 
Individual pharmacokinetic parameters, however, will not be included in descriptive statistics 
for plasma concentrations, pharmacokinetic parameters or other statistical assessment.
Assessment of dose proportionality
Dose proportionality will be assessed using the secondary pharmacokinetic endpoints as 
specified in Section 5.5.1.2. Two separate analyses will be performed, one for the doses 
under fasting conditions, and one for the doses under fed conditions.
The basic model for the investigation of dose proportionality will be a power model that 
describes the functional relationship between the dose and PK endpoints.

computed. Perfect dose proportionality would correspond to a slope of 1. The assumption of a 
linear relationship between the log-transformed pharmacokinetic endpoint and the log-
transformed dose will be checked.
If dose proportionality over the entire dose range investigated cannot be shown, an attempt 
will be made to identify dose range(s), where dose proportionality can be assumed.

Graphical displays: To support the analyses of dose proportionality, graphical representations 
of the data might be created. These might include (but are not limited to) individual time-
courses of trough plasma concentrations and the gMean plasma concentration time profiles.
Food effect part
The secondary parameters (see Section 5.5.1) will be calculated according to the BI SOP 
‘Standards and processes for analyses performed within Clinical Pharmacokinetics/ 
Pharmacodynamics’ [001-MCS-36-472] and will statistically be assessed using the same

Safety analyses
Safety will be assessed for the endpoints listed in Section 5.2.1. All treated subjects (i.e., all 
subjects who received at least one dose of study drug), will be included in the safety analysis. 
Safety analyses will be descriptive in nature and will be based on BI standards. No hypothesis 
testing is planned.

The analyses will be done by ‘treatment at onset’.
Treatments will be compared in a descriptive way.
In the single rising dose parts, the placebo control group in the safety evaluation will consist 
of all placebo treated subjects, regardless of the dose group in which they were treated and 
regardless of whether they participated in the single rising dose part under fed or under 
fasting conditions; the active treatment groups will be compared to the placebo group in a 
descriptive way. To explore potential differences between placebo subjects under fasting and 
under fed conditions, these two subgroups will be compared descriptively.
In all (single rising dose – fasting and fed - and food effect) parts, 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 ECG, vital signs, or laboratory parameters) or AEs will be assigned to 
treatments (see Section 4.1) based on the actual treatment at the planned time of the 
measurement or on the recorded time of AE onset (concept of treatment emergent AEs).
Therefore, measurements planned or AEs recorded prior to first intake of trial medication will 
be assigned to 'screening', those between first trial medication intake until the end of trial visit 
will be assigned to the treatment period. These assignments including the corresponding time 
intervals will be defined in detail in the TSAP. Please note that AEs occurring after the last 
per protocol contact but entered before database lock will be reported to drug safety only and 
will not be captured in the trial database.
Additionally, further treatment intervals (analysing treatments) may be defined in order to 
provide summary statistics for time intervals, such as combined treatments, on-treatment 
totals or periods without treatment effects (such as screening and post-study 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 5.2.2.1) and 
other significant AEs (according to ICH E3) will be listed separately.
Laboratory data will be compared to their reference ranges. Values outside the reference 
range as well as values defined as clinically relevant will be highlighted in the listings. 
Additionally, differences from baseline will be evaluated.
Vital signs or other safety-relevant data observed at screening, baseline, during the course of 
the trial and at the end-of-trial evaluation will be assessed with regard to possible changes 
compared to findings before start of treatment.
For the single rising dose parts (under fasting and fed conditions) of the study, a centralised 
evaluation of all 12-lead ECGs recordings (see Section 5.2.4) will be the basis for the 
derivation of further ECG parameters based on the ECG variables QT, HR, QTcF, QTcB, PR, 
QRS, and RR. The baseline value of an ECG variable is defined as the mean of the triple
ECG measurements prior to drug administration. The derivation of the quantitative and 
qualitative ECG endpoints and their analyses will be described in the TSAP.

Interim analyses
Single rising dose parts under fasting and fed conditions
Preliminary safety analysis
No formal interim safety analysis is planned. However, if safety reasons require a preliminary
safety analysis of ECG data, a part of the staff of the ECG laboratory may be unblinded. This
part of the staff is strictly separated from the other part of the staff, which is involved with
interval measurements and assessments of single ECGs (they keep blinded).
Preliminary PK analyses
A preliminary analysis of PK parameters (Cmax and AUC0-24 of BI 705564) provided as 
individual values and gMeans at least of the first cohort per dose level, will be performed for 
each dose group before proceeding to the next higher level. Data from the first cohorts of the 
above mentioned dose levels will be sufficient as long as the data from at least 2 subjects on 
active are available.
In contrast to the final PK calculations, the preliminary analysis will be based on planned
sampling times rather than on actual times, regardless of whether actual times were within the
time windows or not. Therefore, minor deviations of preliminary and final results may occur.
The preliminary results will be distributed to the investigator and the trial team.
Depending on the results of available preliminary PK analyses, the tolerability and safety of
the compound, and changes of dosing schedule (e.g. additional intermediate doses),
additional PK preliminary analysis may be performed based on the request of the Trial 
Clinical Monitor, the investigator, or Trial Clinical Pharmacokineticist. No formal 
preliminary PK/PD report will be written.
No inferential statistical interim analysis is planned. However, after each dose group the
investigator (or 
 deputy) is allowed to postpone further dose progression until a
preliminary analysis of the data already obtained has been performed.
Food effect part
Preliminary PK analyses
A preliminary analysis of PK parameters (Cmax and AUC0-24 of BI 705564), provided as 
individual values and gMeans, will be performed before proceeding to the next higher level. 
Data from at least 6 subjects are needed to be available before proceeding to the next higher 
level.
In contrast to the final PK calculations, the preliminary analysis will be based on planned 
sampling times rather than on actual times, regardless of whether actual times were within the 
time windows or not. Therefore, minor deviations of preliminary and final results may occur.

The preliminary results will be distributed to the investigator and the trial team.
No formal preliminary PK/PD report will be written.
Note: Due to global amendment No 4, only one dose level (10 mg) is given in the food effect 
part. Therefore, proceeding to the next higher level in the food effect part is not applicable.
7.3.6
Pharmacokinetic analyses
The pharmacokinetic parameters listed in Section 5.5.1 for drug BI 705564 will be calculated 
according to the BI SOP ‘Standards and processes for analyses performed within Clinical 
Pharmacokinetics/Pharmacodynamics’ [001-MCS-36-472].
Subjects who are not included in the PKS (see Section 7.3.1) will be reported with their 
individual plasma (single rising dose parts under fasting and fed conditions, and food effect
part) and urine (single rising dose parts, only) concentrations and individual pharmacokinetic 
parameters; however, they will not be included in descriptive statistics for plasma (single 
rising dose parts under fasting and fed conditions and food effect part) and urine (single 
rising dose parts, only) concentrations or pharmacokinetic parameters.
Only concentration values within the validated concentration range and actual sampling times 
will be used for the calculation of pharmacokinetic parameters. Concentrations used in the 
pharmacokinetic calculations will be in the same format provided in the bioanalytical report, 
(i.e., to the same number of decimal places provided in the bioanalytical report).
If a pre-dose concentration value is greater than 5% of Cmax, the subject’s pharmacokinetic 
data will be not included in any statistical evaluations, in accordance with international 
guidance. The individual pharmacokinetic parameters of such a subject will be calculated and 
listed separately. If a pre-dose concentration is above BLQ, but less than or equal to 5% of 
the subject’s Cmax value, the subject’s data without any adjustments will be included in all 
pharmacokinetic measurements and calculations.

HANDLING OF MISSING DATA
7.4.1
Safety
With respect to safety evaluations, it is not planned to impute missing values.
7.4.2
Plasma/urine drug concentration - time profiles
Handling of missing PK data will be performed according to the relevant SOP of the Sponsor 
[001-MCS-36-472].
Drug concentration data identified with NOS (no sample available), NOR (no valid result), 
NOA (not analysed), BLQ (below the lower limit of quantification), or NOP (no peak 
detectable) will be displayed as such and not replaced by zero at any time point (this rule also 
applies also to the lag phase, including the pre-dose values).
7.4.3
Pharmacokinetic parameters
Handling of missing PK data will be performed according to the relevant SOP of the Sponsor 
[001-MCS-36-472].
For the non-compartmental analysis, concentration data identified with NOS, NOR or NOA 
will generally not be considered. Concentration values in the lag phase identified as BLQ or 
NOP will be set to zero. All other BLQ/NOP values of the profile will be ignored. The lag 
phase is defined as the period between time zero and the first time point with a concentration 
above the quantification limit.
7.5
RANDOMISATION
Single rising dose parts under fasting and fed conditions
Each dose group will be divided into two cohorts. The subjects of the first cohort will not be 
randomised to maintain a treatment sequence of active-placebo-active-active due to safety 
reasons. In the second cohort of each dose level the subjects will be assigned to active or 
placebo treatment using a 3:1 allocation ratio.
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, which 
involves 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 (see
Section 3.3.5).

DETERMINATION OF SAMPLE SIZE
Single rising dose part under fasting conditions
It is planned to include a total of 48 subjects in this part of the 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 studies of the present 
type and is in general considered as sufficient for the exploratory evaluation of single dose 
safety and pharmacokinetics [R95-0013].
Single rising dose part under fed conditions
It is planned to include a total of 32 subjects in this part of the 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 studies of the present 
type and is in general considered as sufficient for the exploratory evaluation of single dose 
safety and pharmacokinetics [R95-0013].
Food effect
It is planned to enter a total of 12 subjects in this part of the trial. The planned sample size is 
not based on a power calculation but is judged to be adequate to attain reliable results and to 
fulfil the objectives and requirements of this exploratory trial.
With a sample size of 12 subjects, the following precision of the ratio of gMeans (test/
reference) can be expected. Precision is defined as the ratio of upper to lower confidence 
interval limit. Note that the precision is independent of the actual ratio of gMeans.
For this trial, no information on intra-subject variability is available from previous trials. 
Therefore, Table 7.6: 1 provides an overview on the achievable precision for estimating the 
ratio of gMeans (test/ reference) for three different gCV. For illustrative purposes, the
expected 90% confidence intervals with 95% coverage probability are displayed for different
values of gMeans ratios T/R in the two-period two-sequence crossover design.

INFORMED CONSENT, DATA PROTECTION, TRIAL
RECORDS
The trial will be carried out in compliance with the protocol, the principles laid down in the 
Declaration of Helsinki, in accordance with the ICH Harmonised Tripartite Guideline for 
Good Clinical Practice (GCP) and relevant BI SOPs.
The investigator should inform the sponsor immediately of any urgent safety measures taken 
to protect the study subjects against any immediate hazard, and also of any serious breaches 
of the protocol or of ICH GCP.
As a general rule, no trial results should be published prior to finalisation of the CTR.
Insurance coverage: The terms and conditions of the insurance coverage must be given to 
each subject and are made available to the investigator via documentation in the ISF.
8.1
STUDY APPROVAL, SUBJECT INFORMATION, AND INFORMED 
CONSENT
This trial will be initiated only after all required legal documentation has been reviewed and 
approved by the respective Institutional Review Board (IRB) / Independent Ethics Committee 
(IEC) and competent authority (CA) according to national and international regulations. The 
same applies for the implementation of changes introduced by amendments.
Prior to a subject’s participation in the trial, written informed consent must be obtained from 
each subject (or the subject’s legally accepted representative) according to ICH GCP and to 
the regulatory and legal requirements of the participating country. Each signature must be 
personally dated by each signatory and the informed consent and any additional subject 
information form are to be retained by the investigator as part of the trial records. A copy of 
the signed and dated written informed consent and any additional subject information must be 
given to each subject or the subject’s legally accepted representative.
The subject must be informed that his personal trial-related data will be used by BI in 
accordance with the local data protection law. The level of disclosure must also be explained 
to the subject.
The subject must be informed that his medical records may be examined by authorised 
monitors (Clinical Monitor Local/Clinical Research Associate) or Clinical Quality Assurance 
auditors appointed by BI, by appropriate IRB/IEC members, and by inspectors from 
regulatory authorities.
8.2
DATA QUALITY ASSURANCE
A quality assurance audit/inspection of this trial may be conducted by the sponsor or 
sponsor’s designees, by IRBs/IECs, 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.

Section 4.1.8.
 
 
 
8.3.1
Source documents
Source documents provide evidence for the existence of the subject and substantiate the 
integrity of the data collected. Source documents are filed at the investigator’s site.
All data reported in the CRFs must be consistent with the source data or the discrepancies 
must be explained.
Data directly entered into 
(that is, without prior written or electronic record) are 
considered to be source data. The place where data is entered first will be defined in a trial 
specific Source Data Agreement. The data in 
are available for inspection at any 
time.
The investigator may need to request previous medical records or transfer records, depending 
on the trial.
8.3.2
Direct access to source data and documents
The investigator/institution will permit trial-related monitoring, audits, IRB/IEC review and 
regulatory inspection, providing direct access to all related source data/documents. CRFs and 
all source documents, including progress notes (if applicable) and copies of laboratory and 
medical test results must be available at all times for review by the sponsor’s clinical trial 
monitor, auditor and inspection by health authorities (e.g. FDA). The Clinical Research 
Associate/on site monitor and auditor may review all CRFs, and written informed consents. 
The accuracy of the data will be verified by reviewing the documents described in 
Section 8.3.1.
8.3.3
Storage period of records
Trial site
The trial site must retain the source and essential documents (including ISF) according to the 
national or local requirements (whichever is longer) valid at the time of the end of the trial.

Section 9
Description of change
-
Single rising dose part under fed conditions
added, with single doses of 20 mg, 40 mg, 
80 mg, and 160 mg BI 705564 or placebo, 
given following a high-fat, high-calorie 
breakfast. Design and study procedures in the 
single rising dose part under fed conditions 
are identical to the pre-existing single rising 
dose part under fasting conditions with the 
following exceptions:
o
Addition of high-fat, high-calorie 
breakfast prior to administration of 
BI 705564
o
Modification of sampling for blood for 
 
o
No stability samples will be taken
o
No samples for metabolite 
identification will be taken.
o
Safety laboratory at time point +4 h is 
not at fasting conditions (due to the 
breakfast taken before administration 
of BI 705564)
-
Up to 2 additional dose groups may be 
investigated in the single rising dose part 
under fed conditions.
-
No additional dose groups may be 
investigated in the single rising dose part 
under fasting conditions.
-
Number of subjects changed: Total entered 
number increased from 88 to 92; number in 
single rising dose part under fasting condition 
reduced from 64 to 48; number in food effect 
part reduced from 24 to 12; number of 
subjects in single rising dose part under fed 
conditions added as 32 subjects. Additional 
subjects can be included in single rising dose
part under fed conditions (up to 16 additional 
subjects) in order to test up to 2 additional 
doses, provided the planned and approved 
highest dose will not be exceeded, i.e. the 
total number of subjects in the trial (all three 
parts together) may be higher than 92 but not 
higher than 108 subjects.

-
Test product BI 705564 as 100 mg tablet and 
corresponding placebo tablet are not 
applicable to the amended single rising dose 
part under fasting conditions.
-
In the single rising dose part under fasting
conditions, doses 120 mg and 160 mg are not 
given (dose groups 7 and 8 in the single rising 
dose part under fasting conditions are 
deleted).
-
In the food effect part, only one dose (10 mg) 
is tested. The dose of 40 mg is not tested in 
the food effect part. 
-
Flow Chart 3 added.
-
Minor editorial changes.
-
Update of IB reference to version 2.
-
Deletion of statement that doses will be 
increased with decreasing escalation factors.
-
Change of wording of primary objective in 
order to include both the single rising dose 
part under fasting and the part under fed 
conditions.
-
Change of risk minimization wording to 
explain that in the single rising dose part 
under fed conditions, escalation factors of 2 
are chosen.
-
Addition of Section 7.3.3 to explain statistical 
comparison of PK data from single rising dose 
part fed and single rising dose part fasting.
-
Determination of sample size for single rising 
dose part under fasting conditions and for 
food effect part corrected to reflect the 
changes in subject numbers in the trial parts; 
determination of sample size for single rising 
dose part under fed conditions added.
-
 
-
Drug test “M-10/14-PDT test” added.

-
Doses of 120 mg and 160 mg in the single 
rising dose part under fasting conditions are 
not justified, as no further increase of 
systemic plasma exposure parameters of 
BI 705564 is expected.
-
Additional dose groups are not applicable to 
the single rising dose part under fasting
conditions, as this was not done in this part, 
and the single rising dose part under fasting
conditions is completed.
-
The 40 mg food effect part is neither covered 
by available safety data from the single rising 
dose part under fasting conditions, nor is it 
required, due to addition of a single rising 
dose part under fed conditions.
 
 
 
 
-
New drug test added, because name of drug 
test has been changed (however, test remains 
identical; only change of name).
