Title of trial:
Safety, tolerability, pharmacokinetics and pharmacodynamics of multiple rising oral 
doses of BI 705564 (double-blind, randomised, placebo-controlled, parallel-group 
design) and evaluation of midazolam interaction (nested, open, fixed-sequence, intra-
individual comparison) in healthy male subjects
Principal Investigator:
Trial site:
Clinical phase:
I
Objectives:
(1) To investigate safety, tolerability, pharmacokinetics and pharmacodynamics 
following multiple rising oral doses of BI 705564
(2) To investigate the effect of BI 705564 on the pharmacokinetics of midazolam 
given as oral microdose - in dose group (DG)s 2 to 5
Methodology:
(1) Double-blind, randomised (within dose group), placebo-controlled, parallel-group 
comparison
(2) Nested, open, fixed-sequence, intra-individual comparison - in DGs 2 to 5
No. of subjects: 
total entered:
60* (50 in DGs 1 to 5, and an additional 10 in DG 8)
each treatment:
10 per dose group; 8 on active drug and 2 on placebo
* Additional subjects may be entered to allow testing of additional doses on the basis of 
experience gained during the trial conduct (e.g. preliminary PK data), provided the planned and 
approved highest dose will not be exceeded. Thus, the actual number of subjects entered may 
exceed 50, but will not exceed 70 subjects entered.
Diagnosis:
(1) DGs 1 to 5: Not applicable
(2) DG 8,

Statistical methods:
(1) BI 705564
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.
Linearity index will be estimated using a linear model providing a two-sided 95% CI.
Attainment of steady state will be analysed by a repeated measures linear model for 
trough concentrations (Cmin) of BI 705564 with dose as an additional covariate, if 
permissible.
(2) Midazolam (DGs 2 to 5)
Descriptive statistics will be calculated for all endpoints.
Relative bioavailability will be estimated by the ratios of the geometric means (test/
reference) for the secondary endpoints. Additionally, their two-sided 90% 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 is not specified. The statistical model will be an ANOVA on the 
logarithmic scale including effects for ‘subjects’, and ‘treatment’. CIs will be 
calculated based on the residual error from ANOVA.

1.
Subject must be informed and written informed consent obtained prior to starting any screening procedures. Screening 
procedures include physical examination, check of vital signs, ECG, safety laboratory (including drug screening and 
alcohol breath test), demographics (including determination of body height and weight, smoking status and alcohol 
history), relevant medical history, concomitant therapy and review of inclusion/exclusion criteria. 
2.
Time is approximate. The respective procedure is to be performed and completed within 3 h prior to drug 
administration. 
3.
If several actions are indicated at the same time point, the intake of meals will be the last action.
4.
End of trial examination includes physical examination, body weight, vital signs, ECG, safety laboratory, recording of 
AEs and concomitant therapies.
5.
AEs/ infections/ bleeding events and concomitant therapies will be recorded throughout the trial but will be specifically 
asked for at the time points indicated in the Flow Chart above.
6.
Safety laboratory and SPT to be taken and to be medically evaluated within 3 days prior to first administration of study 
drug. These tests can be omitted, if the screening examination is performed on Days -6 to -4.
8.
The ECG recording has to be performed as triple at this time point. At baseline (Day 1 at -1:30) three pre-dose triplicate 
ECGs within 10 min are to be recorded.
9.
Sampling times and periods may be adapted based on information obtained during the trial (e.g. preliminary PK data) 
including addition of samples and visits as long as the total blood volume taken does not exceed 500 mL per subject.

1.2.1.7
Prediction of human pharmacokinetics and therapeutic dose
Information available for DGs 1 to 5
The metabolic clearance (CL) of BI 705564 in human is predicted to be 6.2 mL/min/kg, as
determined by scaling of metabolic stability data obtained from incubations with human
hepatocytes [n00250613-02]. The Vss in human is predicted to be 2.0 L/kg based on mean
body weight-normalized Vss values obtained from PK studies in rat, dog, and monkey. The
effective half-life value in human is predicted to be 3.7 h which was estimated based on the 
projected CL and Vss values. Human bioavailability is predicted to be 10% based on the dog
bioavailability data corrected by the difference in estimated hepatic first-pass extraction
between dog and human.

 the therapeutic
dose of BI 705564 (free base) is predicted to be 12 mg q.d. with a corresponding Cmax,ss of
12 nM and an AUCss of 89 nM•h.
In study 1408-0001, a single dose of 20 mg under fasting conditions resulted in a mean Cmax
of about 13 nM which is in the range of the predicted therapeutic peak exposure. However, 
the mean predicted therapeutic systemic exposure of about 90 nM•h was not reached with a 
single dose of 80mg under fasting conditions (AUC0-24 of about72 nM•h). For details, refer to 
Section 1.2.1.5.
1.2.2
Midazolam (DGs 2 to 5)
Midazolam is a sensitive substrate of CYP3A4, used both in vitro and in vivo as a probe drug 
for CYP3A4 drug interactions. Absorption is rapid, with maximum concentrations reached 
around 15 to 30 min. Clearance is also rapid, with an elimination half-life of 1.5 to 2.5 h. The 
PK of midazolam has been found to be dose proportional over a range of at least 0.001 µg to
3 mg [R17-3022]. For further information, refer to the summary of product characteristics
[R17-3087].

RATIONALE, OBJECTIVES, AND BENEFIT - RISK 
ASSESSMENT
2.1
RATIONALE FOR PERFORMING THE TRIAL
Considerations for DGs 1 to 5
This is the second trial with BI 705564 and the first with multiple dose administrations. The
objective of this trial is to investigate the safety, tolerability, pharmacokinetics and
pharmacodynamics of BI 705564 in male subjects. The chosen population of healthy 
volunteers using multiple rising oral doses is adequate to provide the basis for the phase 2
clinical development program of BI 705564
 This trial 
will provide pharmacokinetic information in healthy volunteers at steady state exposure.
A currently ongoing phase 1 trial, study 1408-0001 (amended) explored safety and 
tolerability in healthy male subjects after single doses. At the time of the original CTA 
submission of this protocol, the dose level of up to 80 mg was completed. Up to this dose 
level there were no dose-limiting AEs and no SAEs. Since in this single dose study the 
exposure was going to plateau from 40 mg onwards and the intake of food increased the 
exposure, the multiple dose study was performed under fed conditions.
Based on in vitro screening data, it cannot be excluded that BI 705564 might be an 
inactivator and/ or inducer of CYP3A4 (for details, refer to Section 1.2.1.4). To exclude a 
clinically relevant CYP 3A4 modulation with BI 705564 as perpetrator, an assessment of the 
effect of BI 705564 on the midazolam metabolism will be conducted in DGs 2 to 5, only. 
Therefore, these dose groups will receive a microdose of midazolam before start and at the 
end of treatment with BI 705564.
The safety- and PK data obtained in this study will contribute to define appropriate doses for 
further clinical studies with BI 705564.

2.2
TRIAL OBJECTIVES
DGs 1 to 5
The primary objective of this trial is to investigate safety and tolerability of BI 705564 in 
healthy male subjects, following oral administration of multiple rising doses of 10 mg, 
20 mg, 40 mg, 60 mg, and 80 mg q.d. over 14 days.
Secondary objectives are the exploration of the pharmacokinetics, including dose 
proportionality and investigation of linearity.
In addition, the effect of BI 705564 on the pharmacokinetics of midazolam, given as an oral 
microdose, will be explored in dose groups 2 to 5.
A description of the endpoints to be determined, and the observations along with specific 
information as how to collect the data for that information, is provided in Section 5.
Additional considerations for DG 8

2.3
BENEFIT - RISK ASSESSMENT
DGs 1 to 5
Participation in this trial is without any (therapeutic) benefit for healthy subjects. Their 
participation in the study, however, is of major importance to the development of BI 705564 
which is expected to offer advantages compared with other BTK inhibitors in non-
oncological indications due to its high selectivity. Subjects in this trial are exposed to risks of 
study procedures and risks related to the exposure to the 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. The 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 (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 nonclinical safety studies.
2.3.2.1
Mode of action
BTK is a well characterized target with known functions in the immune signaling pathways
of B-cells and myeloid cell lineages (refer to Section 1.1). Clinical experience with the 
marketed BTK inhibitor ibrutinib is available (refer to Sections 1.1). 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 can be controlled by 
the application of antibiotics and gammaglobulin substitution, [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.
Haemorrhagic events which also occurred with a thrombocyte count within the reference 
range were reported under the treatment of ibrutinib. The underlying mechanism is believed 
to be an inhibition of collagen induced platelet aggregation. Although similar findings are not 
expect for BI 705564, at this stage of clinical development, subjects will be closely monitored 
throughout the study for bleeding events which includes also the assessment of platelet 
function.

001-MCS-40-106-RD-11 (5.0) / Saved on: 15 Jul 2014
BI 705564 binds irreversibly to the BTK binding site (refer to Section 1.2.1). Therefore, the
reversibility of physiological (on-target) effects may be more linked to the re-synthesis rate of 
the BTK protein than to the PK profile of the compound. The time between BTK inhibition 
and complete recovery of BTK protein in humans is estimated to be between 7 and 10 days, 
with a recovery of 50% after about 2 to 3 days [R16-0021]. Therefore 7 days seems to be the 
minimum time between dose groups and from last administration of study drug until the end 
of trial examination.
2.3.2.2
Nature of the target
The BTK protein is intra-cellularly expressed in myeloid and lymphoid cell lines,
predominantly in the immune system (bone marrow, appendix, lymph nodes, tonsils, and
spleen), and the lung. [R17-0406] Although on-target effects are unlikely to occur after a 
multiple doses 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, although unlikely, in bacterial 
infections. Main safety measures performed throughout the study will be: (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 7 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 (refer to 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 PD 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 largely similar 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, refer to the current version of the IB 
[c12104992-03].
2.3.2.4
Findings in nonclinical safety studies
Documents supporting the submission of this trial with BI 705564 were compiled according 
to Good Clinical Practice (GCP) principles. All pivotal, nonclinical safety studies in support 
of this clinical trial were conducted in compliance with Good Laboratory Practice (GLP). For 
further information, refer to the current version of the IB [c12104992-03].
Safety pharmacology
A decrease in heart rate was observed at 50 mg/kg/day (NOAEL) in the 4-week dog
toxicity study (refer to Section 1.2.1.3) which was not observed at the next lower dose

level of 20 mg/kg/day (NOEL). Reduction of heart rate was also observed after a
single dose of 50 mg/kg in the GLP dog telemetry study in dogs but not at a dose of
20 mg/kg. Heart rate will be intensely monitored throughout the study (refer to Flow
Chart). For further information, refer to current version of IB [c12104992-03].

Toxicology
In the 4-week rat toxicity study (refer to Section 1.2.1.3), a decrease in potassium of 
9 to 16 %, as compared to baseline, was observed in all dose groups. Safety laboratory
monitoring will include this parameter during the conduct of the study (refer to Flow
Chart and Section 5.2.3).
In the same study, dose independent, only partially reversible effects on the pancreas
(i.e. mixed interstitial infiltrates, fibrosis, acinar atrophy, hemorrhage) were noted.
These findings could be qualified as rat specific (refer to Section 1.2.1.3) and should 
not be relevant for humans. Nonetheless, subjects with any medical history of 
pancreatitis at screening will be excluded from the study. In addition, this organ will 
be monitored for any inflammatory signs by the determination of amylase and lipase 
throughout the study. Also, its endocrine function will be monitored by plasma 
glucose measurements (refer to Flow Chart and Section 5.2.3).
In the 4-week dog toxicity study (refer to Section 1.2.1.3), a not recovered B-cell
depletion (down to 34-43%, as compared to baseline) was noted at the highest dose
level of 50 mg/kg/day (NOAEL). Therefore, CD19+ B-cell counts and white blood
counts will be monitored throughout the study. At the very dose level of this study, a 
decrease in heart rate of 11.6 bpm, estimated from the electrocardiograms was 
observed. Intensive ECG monitoring will be performed after dosing throughout the 
study (refer to Flow Chart).
2.3.2.5
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. Refer also to Section 5.2.2.1 - Adverse events of special interest (AESIs).
2.3.2.6
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:
DGs 1 to 5

Careful starting dose selection.

Escalation factors limited to 2 with increasing doses.

For safety reasons, each dose group of 10 subjects (8 on active drug, 2 on placebo) 
will be divided into 2 cohorts of 5 subjects each (4 on active drug, 1 on placebo). Both

cohorts will be dosed in a randomized fashion and each drug administration will be
separated by at least 10 min. For orally administered drugs, this is usually a sufficient 
time frame to observe acute effects.

For each dose group, the 2 cohorts will be separated by at least 70 h (between the first
subjects of each cohort) to account for any intolerability resulting from 3 repeated 
doses of BI 705564. A continuous safety evaluation, including results of safety 
laboratories, ECG readings, recordings of vital signs and adverse events will be 
performed before the individual subject and the subsequent cohort is dosed.

Interim measurements of BI 705564 plasma levels will be performed. Dose escalation 
will be stopped, if the gMean of Cmax or AUC of a dose group exceeds the exposure 
thresholds of 312 nM for Cmax or 975 nM•h for AUC, or, if the estimated gMean of 
above parameters for the next higher dose group is expected to exceed these values. 
Estimations will be done based on preliminary PK results of preceding dose groups 
(refer to Section 7.3.5). This should provide a safety margin to the NOAEL of >20
(refer to Table 1.2.1.3: 1).

If one dose level is safe and shows acceptable tolerability, and if no stopping criterion
is met (refer to Section 3.3.4.2), the next higher dose may be given, keeping a 
minimum dosing interval of 7 days between first subjects of consecutive dose groups
due to the irreversible BTK binding of BI 705564 and the time to complete recovery 
of the BTK protein (refer also to Section 2.3.2.1).

Should any of the single doses, i.e. 20 mg, 40 mg, 60 mg, and 80 mg, tested in the 
ongoing study under fed conditions (1408-0001 – amended) be not safe or exceed the 
predefined above gMean exposure levels, these doses would not be applied in this 
multiple dose setting.

Extensive standard safety laboratory measurements including serum electrolytes,
serum amylase and lipase, differential white blood counts, as well as CD19+ B-cell
and platelet count and bleeding time (modified Ivy method using a Surgicutt) to 
monitor platelet function will be performed before and after study drug administration 
(refer to Flow Chart and Section 5.2.3).

Subjects will be closely monitored for infections and bleeding events throughout the 
study.

Repeated triplet 12-lead ECGs are scheduled throughout the study.

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, refer to Section 3.1.

Subjects will be hospitalized throughout the study from Day-1 (treatment with 
microdose of midazolam in dose groups 2 to 5) to Day 2 (treatment with single dose 
of BI 705564) and from Day 4 to Day 18 (repeated doses of BI 705564 and a single 
midazolam microdose on Day 17 in dose groups 2 to 5) 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 close medical

OVERALL ASSESSMENT AND CONCLUSION
DGs 1 to 5
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, GI complaints and haemorrhagic events 
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 favorable safety profile due to less pronounced 
off-target effects.
Based on numerous published studies [R17-3022, R17-3023], treatment risks with a 
microdose of midazolam (i.e. 1/100 of a pharmacologically active dose) are considered 
unlikely.
Considering preclinical and preliminary data obtained in the first in man study of BI 705564
(1408-0001), the well characterized target structure and its physiologic role in B-cell 
differentiation and function, and taking into account the safety measures described above, 
participation in this multiple dose regimen does not represent an undue risk to healthy 
subjects.
Inhibition of BTK in patients with LN, SLE and rheumatoid arthritis 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, pro-inflammatory 
pathways, BI 705564 may slow or halt disease progression. Considering the medical need 
 
 taking into account the potential 
safety advantage of a highly selective BTK inhibitor, the expected benefit is likely to 
outweigh the potential risks and justifies exposure of healthy volunteers.

OVERALL TRIAL DESIGN AND PLAN
DGs 1 to 5
A total of 50 healthy male subjects is planned to participate in the trial, according to 
5 sequential groups, comprising 10 subjects each. Additional subjects may be entered to 
allow testing of additional doses on the basis of experience gained during the trial conduct 
(e.g. preliminary PK data), provided the planned and approved highest dose will not be 
exceeded. Thus, the actual number of subjects entered may exceed 50, but will not exceed 
70 subjects entered. Such changes may be implemented via non-substantial CTP 
amendments.
The trial design is depicted in Figure 3.1: 1.

DGs 1 to 5
This segment is designed as a double-blind, randomised (within dose group), placebo-
controlled, parallel-group comparison.
Subjects will receive ascending doses of BI 705564 on Day 1 and then over 14 consecutive 
days from Day 4 to Day 17.
Within each dose group, 8 subjects will receive BI 705564 (active drug) and 2 will receive 
placebo. Only one dose is tested within each dose group. Each dose group will consist of 
2 cohorts (5 subjects each, 4 on active drug and 1 on placebo) which will be treated 
subsequently for safety reasons. The time interval between these cohorts will be at least 70 h.
A continuous safety evaluation, including results of safety laboratories, ECG readings, 
recordings of vital signs and adverse events will be performed before the individual subject 
and the subsequent cohort is dosed.
The groups will be investigated consecutively in ascending order of doses, maintaining a time 
interval of at least 7 days between the last drug administration in the previous dose group and 
the first drug administration of the subsequent dose group.
The decision to proceed to the next dose group will be based upon the safety, tolerability and 
PK data of the preceding groups. The next dose will only be given, if, in the opinion of the 
investigator, no safety concerns arose in the preceding group (i.e. no dose-limiting events 
occurred) and, if none of the pre-specified trial-specific stopping criteria were met. For more 
details, refer to 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 anytime 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 (incl. monitoring of bleeding events) in the current and preceding dose groups up 
to at least 48 h of the last dose applied, i.e Visit 2, Day 19, 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 EGG in the current and preceding dose groups up to at least 48 h 
after the last dose, i.e. Visit 2, Day 19.

Vital signs in the current and preceding dose groups up to at least 48 h after the last 
dose, i.e. Visit 2, Day 19.

Clinical laboratory tests (including bleeding time to monitor platelet function and 
CD19+ count) in the current and preceding dose groups up to at least Visit 2, Day 18.

Preliminary PK data for a selected time period, as per Section 7.3.5.


Check of criteria for stopping subject treatment, as per Section 3.3.4.1.
The decision to escalate the dose will be made jointly by the Principal Investigator (or an 
authorised deputy) and the trial clinical monitor (or an authorised deputy) after in-depth 
analysis of all available safety data, especially SAEs (if occurred), AEs (incl. monitoring of 
bleeding events) and out-of-range laboratory results (if considered clinically significant). 
Safety reviews can be conducted face-to-face or by video/ telephone conference. The trial 
clinical monitor is responsible for 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 (after consultation with the sponsor) is allowed to alter the scheduled dose 
levels (e.g. add low and/ or intermediate dose levels) on the basis of experience gained during 
the study, provided the planned and approved highest dose is not exceeded. In this case, the 
total number of subjects in this trial might increase. 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 the Flow Chart. For visit schedules 
and details of trial procedures at selected visits, refer to Sections 6.1 and 6.2, respectively.
Midazolam (DGs 2 to 5)
This segment is designed as a nested, open, fixed-sequence, intra-individual comparison.
The potential interaction of BI 705564 with a CYP3A4 substrate will be assessed separately 
in DGs 2 to 5 and in the subjects receiving placebo. This will be conducted in parallel to the 
multiple dose assessments, using a microdose of midazolam in DGs 2 to 5 (a sensitive 
CYP3A4 substrate) administered at 2 different time points (Day -1 and Day 17).

3.2
DISCUSSION OF TRIAL DESIGN, INCLUDING THE CHOICE OF 
CONTROL GROUP
DGs 1 to 5
For multiple-rising dose trials, the design described in Section 3.1 is viewed favourable under 
the provision not to expose subjects involved to undue risks since the main study objective is 
to investigate safety and tolerability of BI 705564.
With the rising dose design, double-blind conditions regarding the subject’s treatment (active 
drug 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 PD effects. Each dose group consists of 10 subjects 
with 8 on active treatment, and 2 on placebo. The placebo control group includes all subjects 
of all dose groups treated with placebo. 8 subjects per active treatment group are in general 
considered as sufficient for the exploratory evaluation of pharmacokinetics.

After the first dose (single dose segment), a sufficient wash-out period will be included 
before the second dose (first dose of the multiple dose segment) is administered. This will 
allow for appropriate calculation of the PK parameters after a single dose administration and 
for comparison with PK parameters at steady state.
The evaluation of a potential CYP3A4 interaction with BI 705564 using a microdose of 
midazolam is considered to be acceptable. A microdose of midazolam is not expected to have 
any pharmacological effects. Therefore, subjects are not exposed to undue risks. Also, the 
evaluation of the investigational drug should not be influenced. This assessment will allow 
for better judgement regarding acceptable co-medications in a Proof of Clinical Concept 
study and later in the phase 3 development.
3.3
SELECTION OF TRIAL POPULATION
DGs 1 to 5
It is planned that 50 healthy male subjects will enter the study. The actual number of subjects 
entered may exceed the total of 50, if additional intermediate doses will be tested (refer to
Section 3.1).Subjects will be recruited from the volunteers' pool of the trial site.
Only male subjects will be included into the study because hitherto no conclusive data on 
reproductive toxicology are available. With respect to the embryo-fetal risk derived from the 
treatment of male subjects with BI 705564, where it is theoretically possible that relevant 
exposure to BI 705564 may be achieved in women of child-bearing potential (WOCBP) from 
exposure to seminal fluid, male contraception (condom or sexual abstinence) should be used 
in order to avoid exposure of an existing embryo/ fetus [R16-0373] (refer to Section 3.3.3, 
exclusion criterion 23).
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.

5. The subject shows 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 
needs to be followed up according to the ‘DILI checklist’ provided in the ISF.
6. The subject shows repeatedly an absolute B-cell (CD19+) count below 40/µL or a platelet 
count below 100 cells/nL.
7. The subject shows at Day 15 or Day 21 a prolonged bleeding time of above 1440 s, i.e. 
3 x ULN (DG 8, only).
In addition to these criteria, the physician may discontinue subjects at any time based on his 
or her clinical judgment.
A subject can also be removed from the trial, if eligibility criteria are being violated or if the 
subject fails to comply with the protocol (e.g., by non-adherence to dietary rules, or non-
attendance at study assessments).
If a subject is removed, 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 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. If the discontinuation occurs before the end of the 
residual effect period (REP) which is defined as 7 days (refer to Section 5.2.2.2), the 
discontinued subject should, if possible, be questioned for AEs and concomitant therapies at 
or after the end of the REP in order to ascertain collection of AEs and concomitant therapies 
throughout the REP, if not contrary to any consent withdrawal of the subject. These 
discontinuations will be discussed in the CTR.
3.3.4.2
Discontinuation of the trial by the sponsor
Boehringer Ingelheim 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.
2. The expected enrolment goals overall or at a particular trial site are not met.
3. Violation of GCP or the CTP or the contract with BI 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 showed relevant individual QT prolongation, i.e. a QTc increase of greater 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 gMean of Cmax or AUC of a dose group exceeds 
the exposure thresholds of 312 nM for Cmax or 975 nM•h for AUC, or, if the estimated 
gMean of above parameters for the next higher dose group is expected to exceed these 
values. Estimations will be done based on preliminary PK results of preceding dose 
groups (refer to Section 7.3.5).
7. Dose escalation will be stopped, should any of the single doses in study 1408-0001, i.e. 
20 mg, 40 mg, 80 mg and 160 mg, tested in the ongoing study under fed conditions be not 
safe or exceed the predefined above gMean exposure levels (refer to Section 2.3.2.6).
The investigator/ the trial site will be reimbursed for reasonable expenses incurred in case of 
trial termination (except in case of the third reason).
3.3.5
Replacement of subjects
In case some subjects 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. The subjects willing to participate will be recruited to dose groups 
according to their temporal availability. As soon as enough subjects have been allocated to 
1 of the 12 cohorts (2 cohorts per dose group), the following subjects will be allocated to one 
of the other dose cohorts. Therefore, the allocation of subjects to dose cohorts 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 the 
dose groups are not expected.
The list of subject and medication numbers 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 the method 'first come first served'. Once a subject number has been 
assigned, it cannot be reassigned to any other subject.
The randomisation procedure is described in Section 7.5.
4.1.3
Selection of doses in the trial
Doses, selected for this trial, are intended to cover the sub-therapeutic as well as the
estimated therapeutic and supra-therapeutic range and include a safety margin. For details, 
refer to Section 1.2 and 2.1.

BI 705564
DGs 1 to 5
The dose range for this trial was selected on the basis of the data obtained in the then ongoing 
first-in-human single rising dose trial 1408-0001. At that time, dose levels up to 80 mg under 
fasting conditions were well tolerated.
Although a single dose of 20 mg under fasting conditions resulted in a mean Cmax of about 
13 nM (in the range of the predicted therapeutic peak exposure), the mean predicted 
therapeutic systemic exposure of about 90 nM•h was not reached with a single dose of 80 mg 
under fasting conditions (AUC0-24 of about72 nM•h). The reason for testing further doses 
under fed conditions (high-fat, high-calorie breakfast) was the observation in the FE part with 
10 mg that peak exposure (Cmax) increased by about 90% and systemic exposure (AUC0-24) 
by about 60% under food (for details, refer to Section 1.2.1.5).
Due to a short half-life of BI 705564 (refer to Section 1.2.1.5), no major accumulation is 
expected.
Midazolam (DG 2 to 5)
The dose of midazolam used for the DDI evaluation was chosen to be 75 μg which is within 
the definition of a microdose, i.e. a 1/100th of the therapeutic dose (in case of midazolam 
7.5 mg) or 100 μg whichever is smaller. Since midazolam PK is dose proportional ranging 
from the microdose to the therapeutic dose, the microdose should still be able to accurately 
predict CYP3A4 DDI liability, while remaining below a pharmacologically active 
concentration.
A solution for injection was chosen for administration as an oral solution, as a solution for 
injection is meant to be diluted and, thus, there is data available regarding the stability and 
compatibility of a diluted solution. Furthermore, the solution for injection contains 
midazolam in isotonic saline solution, while the oral solution has added excipients, making it 
less than ideal for such a dilution. Finally, the IV solution has been successfully diluted and
administered orally as a microdose in previous clinical studies without any reports of AEs
[R17-3022, R17-3023].
4.1.4
Drug assignment and administration of doses for each subject
The treatments to be evaluated are outlined in Table 4.1.4: 1 below. The number of units for 
placebo corresponds to the number of units of the respective dose level.

The oral solutions for dosing midazolam will be prepared according to the instruction given 
in Appendix 10.1 by pharmacists or qualified pharmacy staff members or qualified medical 
study personnel at the trial site under the responsibility of the investigator.
The trial medication will be administered to the subjects, while in a sitting/ 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 and – if applicable – its preparation 
(e.g. reconstitution), if correct dosage cannot be ensured otherwise. To ensure a dosing 
interval of 24 h, the administration of trial medication should take place at the same time 
every day.
In each treatment, a standard continental breakfast will be served 30 min before drug 
administration. The meal must be completely consumed prior to drug administration. The 
composition of the standard continental breakfast is detailed in Table 4.1.4: 3.

Midazolam (DGs 2 to 5)
This segment 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.
BI 705564
This segment of the trial is designed double-blind with regard to subjects and investigators 
(as well as the research staff at the trial site) in order to eliminate observer or performance 
bias. This means avoiding systematic differences in assessments regarding the subject’s 
treatment (active drug or placebo). According to the rising dose design, the current dose level 
will be known to subjects and investigators.
At the trial site, access to the randomisation schedule is restricted to unblinded pharmacists
and pharmacy staff members. Access to the codes will be controlled and documented by a 
signed confidentiality statement, which will be stored in the TMF. Persons directly involved 
in the clinical conduct of the trial will not have access to the treatment allocation prior to 
database lock.
Regarding the sponsor, the database of this trial will be handled open-label, meaning that the 
trial functions of the sponsor are unblinded (including clinical monitor, data manager, 
statistician, bioanalyst, pharmacokineticist, pharmacometrician, drug metabolism scientist as 
well as dedicated CRO personnel). The objective of the trial is not expected to be affected.
The trial site will only be unblinded after locking of the database.
In addition, the trial bioanalyst/ TCPK/ TCPKa will request the randomisation codes prior to 
official unblinding to perform the interim/ preliminary PK analysis. He or she will confirm in 
writing that the codes will be treated confidentially.
Within the central ECG lab, the staff involved with interval measurements and morphological 
analyses will be blinded with respect to the treatment and also with regard to the recording 
date and time as well as planned time points of the ECGs. The interval measurements for a 
given subject will be performed in a random and blinded sequence by a single technician. No 
more than two different blinded readers will evaluate the ECGs of the study.
If an interim safety analysis of ECG data is required, a part of the staff of the ECG laboratory 
may be unblinded. This part of the staff is strictly separated from that part of the staff which 
is involved with interval measurements and assessments of single ECGs (blinded).

Procedures for emergency unblinding
BI 705564
For the blinded segment of this trial, the investigator will be supplied with a set of sealed 
envelopes containing the medication codes for each subject according to the randomisation 
scheme. The envelopes will be kept unopened at the trial site until the end of data collection. 
An envelope may only be opened in emergency situations when the identity of the trial drug 
must be known to the investigator in order to provide appropriate medical treatment or to 
assure safety of trial participants. If the envelope for a subject is opened, the sponsor must be 
informed immediately. The reason for opening the code break must be documented on the 
envelope or appropriate CRF page along with the date and the initials of the person who 
broke the code. At the close-out visit all envelopes are collected.
Midazolam (DGs 2 to 5)
As this part of the trial will be conducted in an open fashion, the treatment information will 
be known. Therefore, no emergency envelopes will be provided.
4.1.6
Packaging, labelling, and re-supply
Drug supplies will be provided by the Department of Pharmaceutical Development of 
Boehringer Ingelheim Pharma GmbH & Co. KG, Biberach, Germany.
The clinical trial supply consists of containers holding the trial medication which are labelled
with trial identification. The required information according to the German Drug Law as well 
as Annex 13/EU GMP Guideline will be provided on the containers. Smaller boxes/ bottles
within the clinical trial supply containers will be labelled with:

BI trial number,

Name of product and strengths or identification code,

Pharmaceutical dosage form, quantity of dosage units,

Route and mode of administration,

Term ‘For Clinical Trial Use’ (domestic language),

Sponsor name and address,

Storage conditions,

Use-by date,

Subject or medication number (or for midazolam a placeholder for subject number),

Batch number.
Ampules will be labelled with the reduced requirements.
The telephone number of the sponsor and name, address and telephone number of the trial 
site are given in the subject information form. The EudraCT number is indicated on the title 
page of this protocol as well as on the subject information and informed consent forms. 
Examples of the labels will be available in the ISF.

4.1.7
Storage conditions
Drug supplies will be kept in their original packaging and in a secure limited access storage 
area according to the recommended (labelled) storage conditions. Where necessary, a 
temperature log must be maintained to make certain that the drug supplies are stored at the 
correct temperature. If the storage conditions are found to be outside the specified range, the 
local clinical monitor (as provided in the list of contacts) is to be immediately contacted.
4.1.8
Drug accountability
The investigator/ pharmacist/ investigational drug storage manager 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,

Availability of a signed and dated clinical trial contract between the sponsor and the 
head of the trial site,

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/ pharmacist/ investigational drug storage manager 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/ pharmacist will maintain records that document adequately that 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/ pharmacist must verify 
that no remaining supplies are in the investigator’s possession.

4.2.2.2
Restrictions on diet and life style
DGs 1 to 5
While admitted to the trial site, 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 Chart. No food is allowed for at least 4 h after the first and last drug 
intake (Days -1, 1 and 17). On the remaining days (Days 4 to 16), food is not allowed for at 
least 2 h after drug intake.
From 1 h before drug intake until lunch, fluid intake is restricted to the water administered 
with the drug, and an additional 240 mL of water served on Days -1, 1 and 17 at 2 h and 4 h 
post-dose (mandatory for all subjects).
During the days of urine collection, total fluid intake should be at least 1 litre and should not 
exceed 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 the first administration of trial medication until after the last 
PK sample is collected.
Alcoholic beverages are not permitted starting 48 h before administration of trial medication 
until after the last PK sample 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 h before administration of first 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 urinary excretion (not applicable for DG 8) 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, refer to Section 3.3.4.1.

Endpoints of efficacy
No efficacy endpoints will be evaluated in this trial.
5.1.2
Assessment of efficacy
Not applicable.
5.2
SAFETY
A continuous safety evaluation, including results of safety laboratories, ECG readings, 
recordings of vital signs and adverse events will be performed before the individual subject 
and the subsequent cohort is dosed.
5.2.1
Endpoints of safety
Primary endpoint to assess safety and tolerability of BI 705564 is the number [N (%)] of 
subjects with adverse reactions.

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.
Serious adverse event
A serious adverse event (SAE) is defined as any AE which fulfils at least one of the 
following criteria:

Results in death,


Is life-threatening, which refers to an event in which the patient was at risk of death at 
the time of the event; it does not refer to an event that hypothetically might have 
caused death, if more severe,

Requires inpatient hospitalisation,

Requires prolongation of existing hospitalisation,

Results in persistent or significant disability or incapacity, or

Is a congenital anomaly/birth defect, or

Is deemed serious for any other reason, if it is an important medical event when based 
upon appropriate medical judgment which may jeopardise the patient and may require 
medical or surgical intervention to prevent one of the other outcomes listed in the 
above definitions.
Examples of such events are intensive treatment in an emergency room or at home for 
allergic bronchospasm, blood dyscrasias or convulsions that do not result in hospitalisation or 
development of dependency or abuse. 
AEs considered ‘Always Serious’
Cancers of new histology and exacerbations of existing cancer must be classified as a serious 
event regardless of the duration between discontinuation of the drug and must be reported as 
described in Section 5.2.2.2, subsections ‘AE collection’ and ‘AE reporting to sponsor and 
timelines’.
In accordance with the European Medicines Agency initiative on Important Medical Events, 
Boehringer Ingelheim has set up a list of further AEs which, by their nature, can always be 
considered to be ‘serious’ even though they may not have met the criteria of an SAE as 
defined above.
The latest list of ‘Always Serious AEs’ can be found in the eDC system. These events should 
always be reported as SAEs as described above.
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. 
AESIs need to be reported to the sponsor’s Pharmacovigilance Department within the same 
timeframe that applies to SAEs, please see above.
The following are considered as AESIs:

Hepatic injury
A hepatic injury is defined by the following alterations of hepatic laboratory 
parameters
1.
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
2.
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. 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 (severity) of AEs
The intensity (severity) of the AE should be judged based on the following:
Mild:
Awareness of sign(s) or symptom(s) that is/are easily tolerated
Moderate: Sufficient discomfort to cause interference with usual activity
Severe:
Incapacitating or causing inability to work or to perform usual activities
Causal relationship of AEs
Medical judgment should be used to determine the relationship, considering all relevant 
factors, including pattern of reaction, temporal relationship, de-challenge or re-challenge, 
confounding factors such as concomitant medication, concomitant diseases and relevant 
history.
Arguments that may suggest that there is a reasonable possibility of a causal relationship 
could be:

The event is consistent with the known pharmacology of the drug,

The event is known to be caused by or attributed to the drug class,

A plausible time to onset of the event relative to the time of drug exposure,

Evidence that the event is reproducible when the drug is re-introduced,

No medically sound alternative aetiologies that could explain the event (e.g. pre-
existing or concomitant diseases, or co-medications),

The event is typically drug-related and infrequent in the general population not 
exposed to drugs (e.g. Stevens-Johnson syndrome),

An indication of dose-response (i.e. greater effect size if the dose is increased, smaller 
effect size if dose is 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
AE 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 Chart. Assessment will be made using non-specific questions 
such as ‘How do you feel?’. Specific questions will be asked wherever necessary in order to 
more precisely describe an AE.
In DGs 1 to 5, as of Day 4, subjects will be questioned and examined for bleeding events at 
the time points indicated in the Flow Chart.
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  until an individual subject’s end of trial:
1.
All AEs (serious and non-serious) and all AESIs
2.
The only exception to this rule are AEs (serious and non-serious) and AESIs in 
phase 1 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: 
1.
The investigator does not need to actively monitor the subject for AEs but should 
only report related SAEs and related AESIs of which the investigator may 
become aware of by any means of communication, e.g. phone call. Those AEs 
should, however, not be reported in the CRF.

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 at this early stage of development and
therefore conservatively defined as 7 days (for details, refer to Section 2.3.2.1). Therefore, all 
AEs reported until the end of trial examination (last per protocol contact) will be considered 
on treatment. 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 h) 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 following should also be recorded as an (S)AE in the CRF and BI SAE form (if 
applicable):

Worsening of the underlying disease or of other pre-existing conditions.

Changes in vital signs, ECG, physical examination and laboratory test results, if they 
are judged clinically relevant by the investigator.
If such abnormalities already pre-exist prior to trial inclusion they will be considered 
asbaseline conditions and should be collected in the CRF only.
All (S)AEs, including those persisting after individual subject’s end of trial must be followed 
up until they have resolved, have been assessed as ‘chronic’ or ‘stable’, or no further 
information can be obtained.

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 Chart 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.
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 a clinically relevant abnormality in the automatic blood cell count or in 
the urinalysis, respectively.
The bleeding time will be measured by a modified Ivy method using a Surgicutt (Adult)
[R17-3223].

To encourage compliance with alcoholic restrictions, a breath alcohol test 
 
will be performed at screening and at admission to trial site, 
and may be repeated at any time during the study at the discretion of an investigator or his/ 
her designee. The results will not be included in the CTR.

Electrocardiogram
5.2.4.1
12-lead resting ECG
Recording
Twelve-lead resting ECGs (I, II, III, aVR, aVL, aVF, V1 - V6) will be recorded using a 
computerised electrocardiograph 
 
at the time points given in the Flow Chart. 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.
To achieve a stable heart rate at rest and to assure high quality recordings, the site personnel 
will be instructed to assure a relaxed and quiet environment so that all subjects are at 
complete rest. All ECGs will be recorded for a 10-second duration after subjects have rested 
for at least 5 min in a supine position. ECG recording will always precede all other study 
procedures scheduled for the same time point (except for blood drawing from an intravenous 
cannula that is already in place) to avoid compromising ECG quality.
ECGs will be recorded as single ECGs or as triplicate ECGs (i.e. three single ECGs recorded 
within 180 sec) as indicated in the Flow Chart.
ECGs may be repeated for quality reasons for instance due to alternating current artefacts, 
muscle movements, or electrode dislocation. For repetition within triplicate ECGs the time 
window of 180 s applies as well. The repeat ECGs are assigned to the respective scheduled 
time point. 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 in the sponsor’s database.
Unscheduled ECGs will not be included into the statistical analysis of interval lengths.

Data transfer
ECGs, taken at time points specified in the Flow Chart, will be transferred electronically to 
the central ECG lab
for evaluation.
In case of repeat ECGs due to quality reasons, only the repeated ECG recordings will be 
transferred to the central ECG lab, whereas the initially recorded ECGs will be discarded.
Unscheduled ECGs (for safety reasons) will be transferred to the central ECG lab but will not 
be included into the statistical analysis of interval lengths.
Data transfer from the central ECG lab to the sponsor is described in the ECG data transfer 
agreement (refer to TMF).
Evaluation
1.
Central ECG lab
Central ECG lab evaluation (of Visit 2 ECGs only) will be performed for the first of 
three replicate ECGs per time point given in the Flow Chart. 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 baseline, where 3 triplicate ECGs are recorded, only the first triplicate ECG (i.e. 3 
single ECGs) will be evaluated.
RR and QT intervals will be determined semi-automatically, whereas PR, QRS 
intervals and QRS-axis are measured automatically by a validated GE 12-SL-
algorithm or equivalent.
Heart rate (HR) and the QT interval corrected for HR (QTc e.g. QTcF and QTcB) will 
be determined by the sponsor (refer also to TSAP for details).
All semi-automatic interval measurements in one subject will be performed on the 
same lead. The intervals will be measured from four cardiac cycles (beats) in lead II. 
If lead II shows a flat T wave or is not measurable for any reason, lead V5 will be 
used, or if that lead is not measurable, then lead I will be used. The lead actually used 
will be reported in the CTR.
For automatic interval measurements no lead will be provided.
For blinding arrangements, refer to Section 4.1.5.1. No more than two blinded readers 
will evaluate all ECGs of the study. ECGs from a particular subject should be 
evaluated by a single reader. For quality assurance and control of measurements, all 
ECGs of a subject will be subsequently reviewed by the ECG technician supervisor or 
his/ her designee to assess the overall variance of the measured intervals and, to detect 
accidental switching of leads and/ or false subject assignments of the ECGs. After 
quality control, the fiducial point markings will be reviewed by the cardiologist 
assigned to the study.
Evaluation of ECGs will comply with the ICH E14 guidance document and 
supplements [R07-4722, R16-0366] as well as the FDA requirements for annotated 
digital ECGs [R09-4830].

2.
Trial site
All local ECGs will be evaluated by the investigator or a designee.
For the inclusion or exclusion (refer also to Section 3.3) of a subject and for the 
assessment of cardiac safety during the study, the QT and QTcB values generated by 
the computerised ECG system or their manual corrections by the investigators will be 
used. In doubtful cases, ECGs may be sent upfront (i.e. prior to the regular data 
transfer) for cardiologic assessment by the central lab. In this case, these centrally 
measured results would overrule any other results obtained.
Abnormal findings, irrespective of whether they originate from central or local evaluation, 
will be reported as AEs (during the trial) or baseline conditions (at screening), if judged 
clinically relevant by the investigator. Any ECG abnormalities will be monitored carefully 
and, if necessary, the subject will be removed from the trial and will receive the appropriate 
medical treatment. 
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, GE Medical Systems, Freiburg, Germany) at the times indicated in the Flow 
Chart, after subjects have rested for at least 5 min in a supine position. All recordings should 
be made using the same type of blood pressure recording instrument on the same arm, if 
possible.
Oral body temperature will be measured at times, indicated in the Flow Chart, using a 
standard device.
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, oral body 
temperature), 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, body weight 
and a physical examination.
As part of questioning for AEs, at time points indicated in the Flow Chart, starting with 
Day 4, subjects will be examined for infections and bleeding events which include, e.g. 
inspection of skin and visible mucosal surfaces (petechial bleeding or bruising), faecal test 
for occult blood and haematuria.

5.4
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 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 PK parameters and 
measurements outlined in Section 5.5 are generally used assessments of drug exposure. The 
biomarkers and PD parameters 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 PK sampling will be recorded in the CRFs.
Actual sampling times will be used for determination of PK 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.
5.5.1
Pharmacokinetic endpoints
The following PK parameters will be determined if feasible:
5.5.1.1
Secondary endpoints

Methods of sample collection
5.5.2.1
Plasma sampling for pharmacokinetic analysis
BI 705564
For quantification of BI 705564 plasma concentrations, 2.7 mL of blood will be taken from 
an antecubital or forearm vein into an K3-EDTA (tripotassium ethylenediaminetetraacetic 
acid)-anticoagulant blood drawing tube at the times indicated in the Flow Chart. Blood will 
be withdrawn by means of either an indwelling venous catheter or by venipuncture with a 
metal needle.
The EDTA-anticoagulated blood samples will be centrifuged for about 10 min 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 120 min, with interim storage of blood samples and aliquots in ice water, 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.

Midazolam (DGs 2 to 5)
For quantification of midazolam plasma concentrations, 4 mL of blood will be taken from an
antecubital or forearm vein into a K3-EDTA-anticoagulant blood drawing tube at the times
indicated in the Flow Chart. Blood will be withdrawn by means of either an indwelling
venous catheter or by venipuncture with a metal needle.
The EDTA-anticoagulated blood samples will be centrifuged for about 10 min 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 1.0 mL plasma the second 
aliquot should contain the remaining plasma. The process from blood collection until transfer 
of plasma aliquots into the freezer should be completed within 120 min, with interim storage 
in ice water, 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

At a minimum, 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 after 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 the Flow 
Chart.
Study measurements and assessments scheduled to occur ‘before’ trial medication 
administration on Day -1(in DGs 1 to5) and Day 1 (in DG 8) 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 ± 30 min is acceptable.
The acceptable deviation from the scheduled time for vital signs, ECG and laboratory tests 
will be ± 15 min for the first 4 h after trial drug administration and ± 30 min thereafter. 
If scheduled at the same time point in the Flow Chart, ECG should be the first and meal the 
last activity. Furthermore, if several measurements, including venepuncture, are scheduled at
the same time, venepuncture should be the last of activities due to its inconvenience to the 
subject and possible influence on physiological parameters with the exception of screening 
and EOT visit.
For planned individual plasma concentration sampling times and urine collection intervals,
refer to the Flow Chart. While these nominal times should be adhered to as closely as 
possible, the actual sampling times must be recorded and will be used for the determination
of PK parameters.
If a subject misses an appointment, it will be rescheduled, if possible. The relevance of 
measurements outside permitted time windows will be assessed no later than at the Blinded 
Report Planning Meeting.
DGs 1 to5
BI 705564 will be administered on Day 1 and on Day 4 through to Day 17 at 0h (planned 
time).
Midazolam will be administered on Day -1 and on Day 17 at 0h.
The tolerance for drug administration on Days -1, 1 and 17 will be ± 1 min. On all other 
treatment days it will be ± 10 min.

DETAILS OF TRIAL PROCEDURES AT SELECTED VISITS
6.2.1
Screening period
After having been informed about the trial, all subjects will give their written informed 
consent in accordance with GCP and local legislation prior to enrolment in the study.
For information regarding laboratory tests (including drug and virus screening), ECG, vital
signs, and physical examination, refer to Sections 5.2.3 to 5.2.5.
6.2.2
Treatment period
Trial medication will be taken orally by each subject under direct supervision of the 
investigator or his/ her designee. Details on treatments and procedures of administration are 
described in Section 4.1.4.
For details on time points and procedures for sample collection refer to Flow Chart and 
Section 5.5.2.
Safety measurements performed during the treatment period are specified in Section 5.2 and

Chart. AEs and concomitant therapy will be assessed continuously from screening until the 
end of trial examination.
DGs 1 to5
Each subject will receive a single dose of BI 705564 or placebo on Day 1 and from Day 4 to 
Day 17 (14 days).
A single midazolam microdose will be administered on Day -1 and on Day 17 (DGs 2 to 5).
Study participants will be admitted to the trial site the morning of Day -1, at which point the 
first midazolam microdose will be administered. They will be kept under close medical 
surveillance for at least 24 h following the first BI 705564 administration on Day 1. Subjects 
will then be allowed to leave the trial site the morning of Day 2, after formal assessment and 
confirmation of their fitness by the investigator or 
 designee. On Day 2 in the evening and 
Day 3 in the morning, the study will be performed in an ambulatory fashion.
In the morning of Day 4, participants will be admitted to the trial site again and kept under
close medical surveillance for at least 24 h following the last drug administration on Day 17.
After this 14 day hospitalization period, subjects will then be allowed to leave the trial site 
after formal assessment and confirmation of their fitness by the investigator or 
designee.

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, refer to 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 
up until they have resolved, have been sufficiently characterized, or no further information 
can be obtained.
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
BI 705564
DGs 1 to 5
The primary objective of this trial is to investigate the safety and tolerability of BI 705564. 
This will be achieved 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 are not planned (as 
explained in Section 7.2).
The secondary objective is the exploration of the pharmacokinetics  and pharmacodynamics 
(PD) of BI 705564. Endpoints, as specified in Sections 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.
Trough concentration values will be analysed regarding attainment of steady state as a pre-
requisite for calculation of steady state parameters. Additionally, the linearity index will be 
estimated, if feasible. PD markers and their percentage change from pre-dose will be 
summarized.
Midazolam (DGs 2 to 5)
The relative bioavailability of midazolam in the presence and absence of BI 705564 will be 
evaluated separately within dose levels 2 to 5 and separately for all subjects receiving 
placebo. For details, refer to Section 7.3.3.
7.2
NULL AND ALTERNATIVE HYPOTHESES
Safety and tolerability of 6 different DGs (DG 3 
will be exposed to 40 mg) of 
BI 705564 are to be determined on the basis of the 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.
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 Blinded Report Planning 
Meeting and provided in the TSAP.
7.3.1
Primary analyses
Analysis of safety and tolerability is described in Section 7.3.4.
7.3.2
Secondary analyses
The secondary parameters (refer to 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 parent drug.
Plasma 
concentration data and parameters of a subject will be included in the
statistical PK analyses, if they are not flagged for exclusion due to a protocol violation 
relevant to the evaluation of PK (to be decided no later than in the Blinded Report Planning 
Meeting) or due to PK non-evaluability (as revealed during data analysis, based on the 
criteria specified below). Exclusion of a subject’s data will be documented in the CTR.
Relevant protocol violations may be:

Incorrect trial medication taken, i.e. the subject received at least one dose of trial 
medication the subject was not assigned to

Incorrect dose of trial medication taken

Use of restricted medications.
Plasma 
concentrations and/ or parameters of a subject will be considered as non-
evaluable if, for example:

Subject experienced emesis that occurred at or before two times median tmax of the 
respective treatment (Median tmax is to be determined excluding the subjects 
experiencing emesis),

Missing samples/ concentration data at important phases of PK disposition curve.

The PK parameter analysis set (PKS) includes all subjects in the Treated Set (TS) who 
provide at least one PK parameter that was not excluded according to the description above.
Assessment of dose proportionality
Dose proportionality will be assessed using the PK endpoints as specified in Section 5.5.1.1.
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 PK 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.

In order to construct a confidence interval for LI, a statistical model using AUCτ,ss and AUC 
0-∞will be set up: A linear model on the logarithmic scale including effects for 'subject' and 
'AUC type' can be applied, where 'subject' is a random effect and 'AUC type' a fixed effect.

and AUC type i; where i = 1 (after first dose) or 2 (after last dose) and j=1, 2,…, 8,

the overall mean,


the AUC type I,
s
the effect associated with subject j (random effect),
e
random error associated with subject j at AUC type i (assumed to be independent 
and identically normally distributed).
A pairwise comparison of both areas via the log transformed difference
log(
,
) = log(,) - log()
will then be performed including calculation of a 2-sided 95% CI. The back transformed
point estimate then represents the estimate of LI. Perfect linearity with respect to multiple 
administrations holds true, if this index equals unity.
Generally, this model will be applied to each dose level separately. If there is evidence that 
the areas are comparable across dose levels, they can be analysed simultaneously. The 
corresponding model will then include the log transformed dose as (additional) covariate.
Attainment of steady state
Attainment of steady state will be explored by using the trough concentrations of BI 705564
between Days 4 and 18 and the concentrations taken directly at the end of the first and the 
last dosing interval for each dose level. Pairwise comparisons of concentrations are 
performed using 2-sided 95% CIs based on the t-distribution. The calculation is based on a 
repeated measures linear model on the logarithmic scale.

Dose can be included as an additional covariate, if there is evidence that the trough 
concentration profiles are comparable across dose levels.
The model will be used to explore the time to steady state by comparing concentrations 
pairwise from different time points: log-transformed differences between all subsequent time 
points (log(Cpre,i/Cpre,j) = log(Cpre,i) - log(Cpre,j), where j>i) will be compared and adjusted 
means (Least Squares Means) as well as 2-sided 95% CIs will be calculated. Thereafter, these 
quantities will be back-transformed by exponentiation to give the corresponding (adjusted) 
ratio and CI.
Comparisons which reveal CIs (for the adjusted ratio) not including 100% will be inspected 
to determine, if the differences between time points are resulting from not yet attaining 
steady-state.
For further details, refer to the TSAP (such as selection of covariance structure and 
comparison of time points).
Graphical displays
To support the analyses of dose proportionality, linearity and attainment of steady state, 
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 (geometric) mean 
plasma concentration time profiles.

7.3.4
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.
Treatments will be compared in a descriptive way. 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. As the treatment duration in DG 8 is different from the treatment duration 
in DGs 1 to 5, all safety outputs for the placebo group will be displayed both, together and 
separately for DGs 1 to 5 and DG 8. The active treatment groups will be compared to the 
placebo group in a descriptive way. Tabulations of frequencies/ proportions will be used for 
the evaluation of categorical (qualitative) data, and tabulations of descriptive statistics will be 
used to analyse continuous (quantitative) data.
The analyses will be done by ‘randomised treatment’.
Measurements (such as ECG, vital signs, or laboratory parameters) or AEs will be assigned to 
treatments (refer to Section 4.1) based on the actual treatment at the planned time of the 
measurement or on the recorded time of AE onset (concept of treatment emergent AEs). 
Therefore, measurements planned or AEs recorded prior to first intake of trial medication will 
be assigned to '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).
AEs will be coded using the Medical Dictionary for Regulatory Activities (MedDRA). 
Frequency, severity and causal relationship of AEs will be tabulated by treatment, system 
organ class and preferred term. SAEs, AESIs (refer to Section 5.2.2.1) 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.
A centralised evaluation of all 12-lead ECGs recordings (refer to Section 5.2.4) will be the 
basis for the ECG variables QT, HR, QTcF, QTcB, PR, QRS, RR, and further derived ECG 
parameters. The baseline value of an ECG variable is defined as the mean of the triplicate
ECG measurements prior to drug administration. The derivation of the quantitative and 
qualitative ECG parameters and their analyses will be described in the TSAP.
7.3.5
Preliminary PK analyses
A preliminary analysis of PK parameters (AUC0-24 and Cmax of BI 705564), provided as 
individual values and geometric means of the first cohort per dose level, will be performed 
for

Dose levels 1, 2, 3 and 5 (n) before proceeding to the subsequent dose level 2, 3, 5 
and 4
(Note: 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 treatment were available).
In contrast to the final PK/ PD 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 analysis will provide individual and mean concentration/effect-time profiles 
and summary statistics of individual values without subject identification. The preliminary 
results will be distributed to the Investigator and the trial team.
Depending on the results of available preliminary PK/ PD analyses, the tolerability and safety 
of the compound, and changes of dosing schedule (e.g. additional intermediate doses),
additional PK/ PD 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 his/her deputy) is allowed to postpone further dose progression until a 
preliminary analysis of the data already obtained has been performed.
7.3.6
PK analyses
The PK 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).

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 (DGs 1 to 5)
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), or BLQ (below the lower limit of quantification) will be displayed as 
such and not replaced by zero at any time point (this rule also applies to the lag phase,
including pre-dose values).
7.4.3
PK 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 will 
be set to zero. All other BLQ 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
Subjects will be randomised within each dose group in a 4:1 ratio which reflects the ratio of 
subjects receiving active drug to placebo.
The sponsor will arrange for the randomisation as well as packaging and labelling of trial 
medication. The randomisation list will be generated using a validated system 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 (refer 
also to Section 3.3.5).
7.6
DETERMINATION OF SAMPLE SIZE
BI 705564
It is planned to include a total of 50 subjects in this trial. The planned sample size is not based 
on a power calculation. The size of 10 subjects per dose group (8 on active treatment, and

2 on placebo) is commonly used in multiple-rising dose studies of the present type and is in 
general considered as sufficient for the exploratory evaluation of multiple dose safety and 
pharmacokinetics.
Additional subjects may be entered to allow testing of additional doses on the basis of 
experience gained during the trial conduct (e.g. preliminary PK data), provided the planned 
and approved highest dose will not be exceeded. Thus, the actual number of subjects entered 
may exceed 50, but will not exceed 70 subjects entered.
Midazolam (DGs 2 to 5)
It is planned to enter a total of 50 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.

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 Boehringer 
Ingelheim in accordance with the local data protection law. The level of disclosure must also 
be explained to the subject.

10.1.2
Dilution procedure
Solution for use with up to 13 subjects
Step 1: 
Open the commercial isotonic saline solution (0.9% NaCl).
Step 2: 
Attach a needle tip to the 3 mL syringe and withdraw a bit more than 1 mL of 
the midazolam solution [concentration: 1 mg/mL] from the originator 
ampoule using a 3 mL syringe.
Step 3:
Remove any air bubbles in syringe (turn upside down and gently push out air 
by depressing the plunger); ensure that exactly 1 mL midazolam solution 
remains in the 3 ml syringe.
Step 4:
Remove and dispose of needle tip; transfer the full 1 mL of midazolam 
solution into an appropriate glass container (with cap) by completely 
depressing the plunger on the 3 mL syringe.
Step 5: 
Attach a needle tip to the 24 mL syringe and withdraw a bit more than 19 mL 
isotonic saline solution into the 24 mL syringe; remove air bubbles (see 
Step 3) and ensure exactly 19 mL isotonic saline solution remains in the 24 ml 
syringe.
Step 6:
Remove and dispose of needle tip; transfer the full 19 mL of isotonic saline 
solution into the same glass container with the midazolam solution by 
completely depressing the plunger on the 24 mL syringe.
Step 7:
Following addition of the midazolam and saline solutions into the glass 
container, ensure the glass container is closed using the corresponding cap. 
The content of the glass container should be mixed thoroughly by swirling 
gently for approximately 1 min.
Step 8:
Extract a little more than 1.5 mL of the dilution solution using a new 3 ml 
syringe; remove bubbles (see Step 3) and ensure that exactly 1.5 mL of the 
diluted midazolam solution (final concentration: 50 µg/mL) remains in the 
3 mL syringe; the solution is now ready for oral administration. 
The final midazolam microdose Oral Solution concentration is 50 ug/mL, for 
administration of 1.5 mL (75 ug), which can be administered per os directly from the 
syringe.

An intermediate dose level of 60 mg will be 
inserted according chapter 3.1 of this CTP. The 
randomised trial medication of DG 5 (160 mg) 
will be used for this dose level (only the 10 mg 
tablets will be administered). Therefore the inter-
mediate dose level will be named DG 5, subject 
numbers will be 501-510. If DG 5 is safe and well 
tolerated it may be followed by the original plan-
ned DG 4 (80 mg). The originally planned dose 
level of 160 mg BI 705564 will not be performed.

Description of change
Insertion of intermediate dose level of 60 mg
Rationale for change
In the light of bleeding time prolongation in all 
subjects on active treatment (expected side effect 
– see 2.3.2.1) and observed cases of haematuria  
[1 subject with macrohaematuria (accompanying 
urinary tract infection), 2 subjects with micro-
haematuria (positive sediment in 1 case)] it was 
decided to reduce the escalation step.

subject: Further application of study medication 
will be stopped, should the subject show at Day 
15 or Day 21 a prolonged bleeding time of above 
1440 s (3 x ULN).
(3) In addition to bleeding time, the closure time 
will be measured with the Innovance® PFA-200, 
using the Dade® PFA Collagen/EPI and the 
Dade® PFA Collagen/ADP test cartridges to 
further monitor and characterize platelet function.

(6) No application of midazolam as micro-dose, 
since the influence of midazolam on BI 705564 
was already characterized in previous DGs.
(7) No measurement of urine PK and plasma 
metabolites, since these parameters were already 
sufficiently characterized in previous DGs.
(8) Correction of inconsistencies regarding the 
unblinding of the study.
(9) Stylistic adjustments and correction of 
typographic errors.
