Criteria for
pharmacodynamics:
Statistical methods:
Descriptive statistics will be calculated for all endpoints.
SRD part: Dose proportionality will be explored under fasted conditions using a 
regression model. A 95% confidence interval for the slope will be computed.
BA part: Relative bioavailability will be estimated by the ratios of the geometric 
means (tablet / PfOS, tablet fed / tablet fasted) for the secondary endpoints. 
Additionally, their two-sided 90% confidence intervals (CIs) will be provided. Since 
the main focus is on estimation and not testing, an acceptance range was not specified. 
The statistical model will be an ANOVA on the logarithmic scale including effects for 
‘sequence’, ‘subjects nested within sequences’, ‘period’ and ‘treatment’.  CIs will be 
calculated based on the residual error from ANOVA.

The primary objective of the SRD part (trial part 1) is to investigate the safety and tolerability 
of BI 730357 in healthy subjects following oral administration of single rising doses after 
fasting and/or non-fasting conditions. The secondary objective is the exploration of the 
pharmacokinetics (PK) including dose proportionality,
of BI 730357 
after single dosing. 
The objective of the BA part (trial part 2) will be to explore the relative bioavailability of 
tablet fasted versus oral solution fasted and the influence of food on the bioavailability of 
tablet fasted versus tablet fed.
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.
2.3
BENEFIT - RISK ASSESSMENT
Participation in this study is without any (therapeutic) benefit for healthy subjects. Their 
participation in the study, however, is of major importance to the development of a new 
orally available drug, which might improve the therapy 
 The 
subjects are exposed to the risks of the study procedures and the risks related to the exposure 
to the trial medication.

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The total volume of blood withdrawn during the entire study per subject will not exceed the 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.
Drug-related risks and safety measures
As the nature of the target and the mechanism of action of BI 730357 are well understood, 
comparable compounds have been tested by other companies before, and the animal models 
are believed to be predictive for the effects in humans, BI 730357 is not seen as a high risk 
compound.
The pharmacological effects of BI 730357 are dose dependent and no evidence for prolonged 
or irreversible effects has been observed. Single doses up to 400 mg BI 739357 are supported 
by preclinical safety data.
During this clinical trial each subject will receive not more than 15 ml solvent consisting of 
PEG 400. PEG 400 is polyethylene glycol with an average molecular weight of 400. 
Polyethylene glycols are commonly used in a variety of pharmaceutical formulations 
including parenteral and oral preparations. They are generally regarded as safe, non-toxic, 
and non-irritant [R99-0697]. PEG 400 was well tolerated, without serious or significant 
adverse events, with doses up to 15 mL per day for 14 days in healthy volunteers [U02-1602].
The following safety measures will be applied in this study in order to minimize the risk for 
healthy volunteers:
∃
Careful dose selection as described in Section 2.1. In addition, dose escalation will be 
shallow and both, starting dose 
) have ample safety margins with respect to
the preclinical findings. Finally, dose selection was based on a sound preclinical 
package including 4 week toxicological studies (not only 2 weeks).
∃
Preliminary measurement of BI 730357 plasma concentrations and preliminary 
determination of PK parameters (Cmax, AUC0-24 see Section 7.3.4).
 
 
 Further dose progression 
would only be allowed after a safety interim analysis and filing and approval of a 
substantial CTP amendment.
∃
An extensive safety laboratory will be performed with special focus on full blood 
exam (see Flow Chart).

∃
For safety reasons, during the single rising dose part each dose group of 8 subjects 
(6 on active, 2 on placebo) will be divided into two cohorts of 4 subjects each (3 on 
active, 1 on placebo). These two cohorts will be separated by at least 48 hours 
(between 1st subject of each cohort),
 
. The first cohort will be dosed in a single blinded, fixed sequence fashion 
(active - placebo - active - active) and the drug administration will be separated by at 
least 60 min between the first 3 subjects. This design ensures that between first and 
second active dose of each dose level there is a time interval of at least 2 hours, which 
is expected to be sufficient to detect relevant acute effects of BI 730357. If BI 730357 
was safe and well tolerated during these initial administrations, the remaining subjects 
of the respective dose level could be dosed as close as 10 minutes apart.
∃
A thorough ECG monitoring including continuous ECG measurement over 6 hours 
post dose to cover the anticipated period of highest drug exposure and additional 
repeated single 12-lead ECGs over 48 hours following drug administration. Dose 
escalation would be stopped as soon as at least 2 subjects at one dose level showed 
relevant QT prolongation (see Section 3.3.4.2 for details).
∃
The subjects will stay at the trial site (BI Human Pharmacology Centre) for at least 
24 hours after study drug administration at each dose level.
 
 
 
∃
During in house-confinement the subjects will be under medical observation and 
thoroughly monitored for both expected and unexpected adverse events.
∃
Only if the respective dose of BI 730357 was safe and showed acceptable tolerability
and if no stopping criterion was met (refer to Section 3.3.4.2), the next higher dose 
will be given at least 6 days later (referring to the 1st subject of each dose group).
∃
Treatments of the BA part (dosing of 25 mg BI 730357) will only start if the 100 mg
dose level of the SRD part was safe and showed acceptable tolerability. 
∃
As reproductive toxicity studies have not yet been conducted, women of child-bearing 
potential will not be enrolled in this study.
∃
 
 
Although rare, a potential for drug-induced liver injury (DILI) is under constant surveillance 
by sponsors and regulators. Therefore, this trial requires timely detection, evaluation, and 
follow-up of laboratory alterations in selected liver laboratory parameters to ensure subjects´ 
safety, see also section 5.2.2.1.
In summary, although not tested in humans to date, BI 730357 has the potential to become an 
oral treatment for

BI 730357 and clinical information from competitor compounds as well as the implemented 
safety measures described above, healthy subjects will not be exposed to undue risks in 
relation to the important information expected from this trial as a basis for further clinical 
development of this compound. Healthy volunteers are not expected to have any direct 
benefit from participation in this FIM clinical trial with BI 730357, as is the usual case in 
such Phase I trials. Considering the medical need of the development of a safer and more 
effective treatment for 
, the Sponsor considers that the benefit 
outweighs the potential risks and justifies exposure of healthy human volunteers.

DESCRIPTION OF DESIGN AND TRIAL POPULATION
3.1
OVERALL TRIAL DESIGN AND PLAN
This first-in-man trial will be conducted in healthy male volunteers at a single centre.
A total of 72 healthy male subjects is planned to participate in 10 sequential groups of 
8 subjects each during the SRD part, and in a group of 12 subjects during the BA part. Within 
each dose group of the SRD part, 6 subjects will receive the active drug and 2 will receive 
placebo. In the BA part, 12 subjects will receive the active drug. The dose groups to be 
evaluated are outlined in Table 3.1: 1 below.

In DG 8 (400 mg/placebo with continental breakfast) and DG 9 (400 mg/placebo with high-fat breakfast) the same 
subjects will be included and treated with the same treatments (i.e. always with active or with placebo) for an intra-
individual comparison of the two different diets (after washout period of at least 14 days)
SRD part
The first part of the trial, the SRD part, is designed as single-blind, partially randomised, and 
placebo-controlled within parallel dose groups. Only one dose is tested within each dose 
group. The groups will be treated consecutively in ascending order of doses. Each group is 
divided into 2 cohorts of 4 subjects each (3 on active drug and 1 on placebo). On the first 
study day within each dose group, the first cohort will be treated in a single-blind manner in 
the following order: first subject (active) followed at least 1 h later by the second subject 
(placebo) followed at least 1 h later by the third subject (active) followed at least 10 min later 
by the fourth subject (active).
If BI 730357 treatment is safe and showed acceptable tolerability in the first cohort, the 
subjects in the second cohort will be treated not earlier than 2 days later in a single-blind 
randomised manner. In the second cohort, a time interval of at least 10 min will be

maintained between each administration of the trial drug to the individual subjects. A time 
interval of at least 6 days will be maintained between the first drug administration in the 
previous dose group and the first drug administration of the subsequent dose group. The 
decision to proceed to the next dose group will be based upon the safety, tolerability, and 
pharmacokinetic data of the preceding dose groups. The next dose will only be given if, in the 
opinion of the Investigator, no safety concerns arose in the preceding dose group (i.e. no 
dose-limiting events occurred) and if none of the pre-specified trial-specific stopping criteria 
were met (refer to Section 3.3.4.2).
A documented Safety Review must take place prior to each dose escalation during the SRD 
part. 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 in the current and preceding dose groups up to at least 48h post dosing, including 
clinically relevant findings from ancillary safety testing listed below (Note: AEs may 
be ongoing at the time of Safety Reviews and AE information may be subject to 
change prior to Database Lock)
∃
Results from 12-lead EGG and continuous ECG monitoring in the current and 
preceding dose groups.
∃
Vital signs in the current and preceding dose groups
∃
Clinical laboratory tests in the current and preceding dose groups
∃
Preliminary PK data as per Section 7.3.4. 
∃
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 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 is allowed to alter the scheduled dose levels (e.g. add an intermediate dose 
level) within the planned and approved dose range or to prolong in-house confinement on the 
basis of experience gained during the study. 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.

fashion. Subjects will be administered BI 730357 as tablet in a fasting state (reference 
treatment R), as oral solution (PfOS) in fasted conditions (test treatment T1) and as tablet 
after a standardised high-fat breakfast (test treatment T2). The three treatments will be 
separated by a washout period of at least 8 days between study drug administrations. Subjects 
will be allocated randomly to one of the six treatment sequences: R/T1/T2, R/T2/T1, 
T1/R/T2, T1/T2/R, T2/R/T1, T2/T1/R.
An overview of all relevant trial activities is provided in the Flow Chart. For visit schedules 
and details of trial procedures at selected visits, refer to Sections 6.1 and 6.2, respectively.

3.2
DISCUSSION OF TRIAL DESIGN, INCLUDING THE CHOICE OF 
CONTROL GROUP
For single-rising dose trials, the design described in Section 3.1 is viewed favourable under 
the provision not to expose the subjects involved to undue risks since the main study 
objective is to investigate safety and tolerability of BI 730357 and the risk to subjects will be 
minimized by studying sequentially ascending doses. For safety reasons the first cohort of 
each dose level will be treated in a fixed treatment sequence (Active-Placebo-Active-Active). 
The dose level being investigated at any time will be known to subjects, but single-blind 
conditions regarding each subject’s treatment (active or placebo) will be maintained for both 
cohorts of each dose level.
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 and tolerability. Each dose group consists of 8 subjects with 6 on 
active treatment, and 2 on placebo. The placebo control group includes all subjects of all dose 
groups treated with placebo. 6 subjects per active treatment group are in general considered 
as sufficient for the exploratory evaluation of pharmacokinetics. 
For the BA part comparing bioavailability of BI 730357 following administration as tablet in 
the fasted state versus oral solution (PfOS) in fasted state as well as tablet in the fasted state 
versus tablet under fed conditions, the crossover design is viewed favourable due to its 
efficiency: since each subject serves as his own control, the comparison between the 
treatments is based on a comparison within subjects rather than between subjects. Thus the 
inter-subject variability is removed from the comparison between treatments [R94-1529]. 
Blinding is not possible because the treatments are distinguishable.
3.3
SELECTION OF TRIAL POPULATION
It is planned that 84 healthy male will enter the study. Subjects will be recruited from the 
volunteers' pool of the trial site. 
Only male subjects will be included into the study because hitherto no data on reproductive 
toxicology are available. With respect to the embryo-fetal risk coming from the treatment of 
male subjects with BI 730357, where it is theoretically possible that relevant exposure to 
BI 730357 may be achieved in women of childbearing potential (WOCBP) from exposure to 
seminal fluid, male contraception (condom or abstinence) should be used in order to avoid 
exposure of an existing embryo/fetus [R16-0373] (see 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.

A subject can also be removed from the trial if eligibility criteria are being violated or if the 
subject fails to comply with the protocol (for instance, by non-adherence to dietary rules, or 
non-attendance at study assessments).
If a subject is removed from or withdraws from the trial prior to first administration of trial 
medication, the data of this subject will not be entered in the case report form (CRF) or trial 
database and will not be reported in the clinical trial report (CTR). If a subject is removed 
from or withdraws from the trial after first administration of trial medication, this will be 
documented and the reason for discontinuation must be recorded in the CRF. In this case, the 
data will be included in the CRF/trial database and will be reported in the CTR. At the time 
of discontinuation a complete end of trial examination will be performed if possible and the 
information will be recorded in the CRFs. If the discontinuation occurs before the end of the 
REP (see 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 the 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 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 based on preliminary PK results (plasma) as soon as 
measured (in at least one subject) or estimated Cmax / AUC0-24 of BI 730357 exceed 
(upper limit of acceptable exposure in this trial, see Section 
2.1). 
3.3.5
Replacement of subjects
In case that there are less than 4 subjects on active per dose level in DG 1-7 of the SRD part 
or less than 9 subjects in the BA part, who do not complete the trial, the trial clinical monitor 
together with the trial pharmacokineticist and the trial statistician are to decide if and how 
many subjects will be replaced. There is no replacement in the SRD part for DGs 8, 9 and 10. 
A replacement subject will be assigned a unique study subject number possessing the same 
treatment, as the subject 
 replaces.

4.1.2
Method of assigning subjects to treatment groups
Prior to the screening visit, subjects of the SRD part 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 18 dose 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 randomisation list with study subject numbers and allocated treatments (SRD part) or 
treatment sequences (BA part) will be provided to the trial site in advance. In both parts of 
the trial, 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 (= medication number) by drawing lots. 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
For the SRD part, oral doses in the range of 2 mg to 800 mg have been selected in order to 
assess the safety and tolerability of BI 730357 in healthy male volunteers, and to investigate 
the PK of 
 The selected doses cover a safe starting dose in the 
sub-therapeutic range, the estimated therapeutic range and potentially supra-therapeutic doses 
within the levels determined by toxicological investigations (see Section 1.2).
The intra-individual comparisons of the BA part investigating the relative bioavailability of 
tablet fasted versus tablet fed and of tablet fasted versus oral solution fasted are planned to be 
conducted with a dose of 25 mg as it is assumed that this dose covers the therapeutic range 
and might be used in the subsequent clinical development.
4.1.4
Drug assignment and administration of doses for each subject
The treatments to be evaluated are outlined in Tables 4.1.4: 1 (SRD part) and 4.1.4: 2 (BA 
part) below. The number of units / dose volume for placebo corresponds to the number of 
units / dose volume of the respective dose level.

The oral solutions for dosing will be prepared according to the reconstitution instruction 
given in Appendix 10.1 under the responsibility of the Investigator. The Investigator can 
decide at any time to discontinue dosing or to decrease the dose escalation by adding 
intermediate doses in case of intolerability or due to safety concerns.
The trial medication will be administered to the subjects, while in a sitting or standing 
position, as an oral dose together with about 240 mL of water under supervision of the
investigating physician or an authorised designee in the morning of Day 1. 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. Administration will be performed following an overnight fast, which is to start no 
later than 10 h before the scheduled dosing. 
In treatment T2 (tablet fed) of the BA part and dose groups 9 (400 mg BI 730357 or placebo) 
and 10 (800 mg BI 730357 or placebo) of the SRD part, a high-fat, high-calorie breakfast will 
be served 30 min before drug administration. In dose group 8 (400 mg BI 730357 or placebo) 
of the SRD part, a standard continental (normal-fat, normal-calorie) breakfast will be served 
30 min before drug administration. The test meals must be completely consumed prior to 
drug administration. The composition of the standard high-fat, high-calorie breakfast will be 
in compliance with the FDA guidance ‘Food-Effect Bioavailability and Fed Bioequivalence 
Studies’ [R03-2269] as detailed in Table 4.1.4: 3. The composition of the standard 
continental breakfast will be detailed in Table 4.1.4: 4.

Subjects will be kept under close medical surveillance until at least 24 h following drug 
administration. During the first 6 hours after drug administration subjects of the SRD part 
will be confined to bed with a bed inclination angle of at least 45 degrees unless lower or 
supine positioning is required for trial-related measurements (e.g. recording of 12-lead ECG). 
During the first 4 hours after drug administration subjects of the BA part will only be allowed 
to lie down if supine positioning is required for trial-related measurements (e.g. recording of 
12-lead ECG). For restrictions with regard to diet see Section 4.2.2.2.
4.1.5
Blinding and procedures for unblinding
4.1.5.1
Blinding
In the present trial, treatments of the SRD part will be blinded to subjects only. With the 
rising dose design, single-blind conditions regarding the subjects' treatment (active or 
placebo) are maintained within each dose group, however the current dose level will be 
known to subjects and Investigators. Treatments of the BA part will be open-label.
The database of this trial will be handled open-label, because no bias with regard to data 
cleaning of safety measures is expected. This is considered acceptable because the potential 
for bias seems to be low and does not outweigh practical considerations. The bioanalyst will 
be blinded for the BA part only.
The bioanalyst of analytical laboratory and the trial pharmacokineticist may receive the 
randomisation codes of the SRD part prior to official unblinding to perform the preliminary 
PK analysis. He or she will treat the codes confidentially.
In addition, the drug metabolism scientist may receive the randomisation codes prior to 
official unblinding to perform metabolites in safety testing analysis (MIST). He or she will 
confirm in writing that the codes will be treated confidentially.
Within the ECG laboratory, the staff involved with interval measurements and assessments 
will be blinded with respect to the treatment within each dose level and also with regard to 
the recording date and time as well as time the 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.

Only authorised personnel as documented in the form ‘Trial Staff List’ may dispense 
medication to trial subjects. The trial medication must be administered in the manner 
specified in the CTP. All unused medication will be disposed locally by the trial site upon
written authorisation by the clinical monitor. Receipt, usage and disposal must be 
documented on the respective forms. Account must be given for any discrepancies. 
The Investigator must maintain records of the product’s delivery to the trial site, the 
inventory at the site, the use by each subject, and the disposal of unused products. 
These records will include dates, quantities, batch / serial numbers, expiry (‘use-by’) dates, 
and the unique code numbers assigned to the investigational products and trial subjects. The 
Investigator will maintain records that document adequately that the subjects were provided 
the doses specified by the CTP, and that reconcile all investigational products received from 
the Sponsor. At the time of disposal, the Investigator must verify that all unused or partially 
used drug supplies have been returned by the clinical trial subject and that no remaining
supplies are in the Investigator’s possession.

OTHER TREATMENTS, EMERGENCY  PROCEDURES,
RESTRICTIONS
4.2.1
Other treatments and emergency procedures
There are no special emergency procedures to be followed. No additional treatment is 
planned. However, in case of adverse events in need of treatment, the Investigator can 
authorise symptomatic therapy. In those cases, subjects will be treated as necessary and, if 
required, kept under supervision at the trial site or transferred to a hospital until all medical 
evaluation results have returned to an acceptable level.
4.2.2
Restrictions
4.2.2.1
Restrictions regarding concomitant treatment
In principle, no concomitant therapy is allowed. All concomitant or rescue therapies will be 
recorded (including time of intake on study days) on the appropriate pages of the CRF.
4.2.2.2
Restrictions on diet and life style
While admitted to the trial site the subjects are restricted from consuming any other foods or 
drinks than those provided by the staff. Standardised meals will be served at the time points 
described in the Flow Chart. No food is allowed for at least 4 h after drug intake.
From 1 h before drug intake until lunch, fluid intake (except for the beverages served with the 
breakfast in the SRD or BA part) is restricted to the water administered with the drug, and an 
additional 240 mL of water served at 2 h and 4 h post-dose (mandatory for all subjects). From 
lunch until discharge from the study centre, liquid intake is restricted to additional 3 litres.

5.1.2
Assessment of efficacy
Not applicable.
5.2
SAFETY

Endpoints of safety
Primary endpoint to assess safety and tolerability of BI 730357 is the number [N (%)] of 
subjects with adverse reactions.
 
5.2.2
Assessment of adverse events
5.2.2.1
Definitions of adverse events
Adverse event
An adverse event (AE) is defined as any untoward medical occurrence in a patient or clinical 
investigation subject administered a medicinal product and which does not necessarily have 
to have a causal relationship with this treatment.
An AE can therefore be any unfavourable and unintended sign (including an abnormal 
laboratory finding), symptom, or disease temporally associated with the use of a medicinal 
product, whether or not considered related to the medicinal product.
Adverse reaction
An adverse reaction is defined as a response to a medicinal product which is noxious and 
unintended. Response in this context means that a causal relationship between a medicinal 
product and an adverse event is at least a reasonable possibility. Adverse reactions may arise 
from use of the product within or outside the terms of the marketing authorisation or from 
occupational exposure. Conditions of use outside the marketing authorization include off-
label use, overdose, misuse, abuse and medication errors.

001-MCS-40-106-RD-11 (5.0) / Saved on: 25 Jun 2014
Serious adverse event
A serious adverse event (SAE) is defined as any AE which:
∃
results in death, 
∃
is life-threatening, this refers to an event in which the patient was at risk of death at 
the time of the event; it does not refer to an event that hypothetically might have 
caused death if more severe,
∃
requires inpatient hospitalisation or prolongation of existing hospitalisation,
∃
results in persistent or significant disability or incapacity, 
∃
is a congenital anomaly/birth defect, 
or 
∃
is to be deemed serious for any other reason if it is an important medical event when 
based upon appropriate medical judgment which may jeopardise the patient and may 
require medical or surgical intervention to prevent one of the other outcomes listed in 
the above definitions.
Medical and scientific judgement should be exercised in deciding whether other situations 
should be considered serious reactions, such as important medical events that might not be 
immediately life threatening or result in death or hospitalisation but might jeopardise the 
patient or might require intervention to prevent one of the other outcomes listed above. 
Examples of such events are intensive treatment in an emergency room or at home for 
allergic bronchospasm, blood dyscrasias or convulsions that do not result in hospitalisation or 
development of dependency or abuse. Any suspected transmission via a medicinal product of 
an infectious agent is also considered a serious adverse reaction.
AEs considered ‘Always Serious’
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 given 
above.
The latest list of ‘Always Serious AEs’ can be found in the RDC system, a remote data 
capture system which allows the entry of trial data at the trial site. These events should 
always be reported as SAEs as described above.
Cancers of new histology and exacerbations of existing cancer must be reported as a serious 
event regardless of the duration between discontinuation of the drug and the occurrence of the 
cancer.
Adverse events of special interest (AESIs)
The term AESI relates to any specific AE that has been identified at the project level as being 
of particular concern for prospective safety monitoring and safety assessment within this trial, 
e.g. the potential for AEs based on knowledge from other compounds in the same class. AESI 
need to be reported to the Sponsor’s Pharmacovigilance Department within the same 
timeframe that applies to SAE, please see above.

The following are considered as AESIs in this trial:
∃
Hepatic injury, as defined by the following alterations of hepatic laboratory 
parameters: 
o
an elevation of AST and/or ALT ≥3-fold ULN combined with an elevation of 
total bilirubin ≥2-fold ULN measured in the same blood sample, and/or
o
marked peak aminotransferase (ALT, and/or AST) elevations ≥10 fold ULN
These lab findings constitute a hepatic injury alert and the patients showing these lab 
abnormalities need to be followed up according to the ‘DILI checklist’ provided in the
ISF. 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.
Intensity of AEs
The intensity of the AE should be judged based on the following:
Mild:
Awareness of sign(s) or symptom(s) that is/are easily tolerated
Moderate:
Enough discomfort to cause interference with usual activity
Severe:
Incapacitating or causing inability to work or to perform usual activities
Causal relationship of AEs
The definition of an adverse reaction implies at least a reasonable possibility of a causal 
relationship between a suspected medicinal product and an adverse event. An adverse 
reaction, in contrast to an adverse event, is characterised by the fact that a causal relationship 
between a medicinal product and an occurrence is suspected.
Medical judgment should be used to determine the relationship, considering all relevant 
factors, including pattern of reaction, temporal relationship, de-challenge or re-challenge, 
confounding factors such as concomitant medication, concomitant diseases and relevant 
history.
Arguments that may suggest that there is a reasonable possibility of a causal relationship 
could be:
∃
The event is consistent with the known pharmacology of the drug 
∃
The event is known to be caused by or attributed to the drug class.
∃
A plausible time to onset of the event relative to the time of drug exposure.
∃
Evidence that the event is reproducible when the drug is re-introduced
∃
No medically sound alternative aetiologies that could explain the event (e.g. pre-
existing or concomitant diseases, or co-medications).
∃
The event is typically drug-related and infrequent in the general population not 
exposed to drugs (e.g. Stevens-Johnson syndrome).

∃
An indication of dose-response (i.e. greater effect size if the dose is increased, smaller 
effect size if dose is diminished).
Arguments that may suggest that there is no reasonable possibility of a causal relationship 
could be:
∃
No plausible time to onset of the event relative to the time of drug exposure is evident 
(e.g. pre-treatment cases, diagnosis of cancer or chronic disease within days / weeks 
of drug administration; an allergic reaction weeks after discontinuation of the drug 
concerned)
∃
Continuation of the event despite the withdrawal of the medication, taking into 
account the pharmacological properties of the compound (e.g. after 5 half-lives). Of 
note, this criterion may not be applicable to events whose time course is prolonged 
despite removing the original trigger.
∃
Additional arguments amongst those stated before, like alternative explanation (e.g. 
situations where other drugs or underlying diseases appear to provide a more likely 
explanation for the observed event than the drug concerned).
∃
Disappearance of the event even though the study drug treatment continues or remains 
unchanged. 
5.2.2.2
Adverse event collection and reporting
AEs collection
Upon enrolment into a trial, the subject’s baseline condition is assessed (for instance, by 
documentation of medical history/concomitant diagnoses), and relevant changes from 
baseline are noted subsequently. 
Subjects will be required to report spontaneously any AEs as well as the time of onset, end, 
and intensity of these events. In addition, each subject will be regularly assessed by the 
medical staff throughout the clinical trial and whenever the Investigator deems necessary. As 
a minimum, subjects will be questioned for AEs (and concomitant therapies) at the time 
points indicated in the Flow Chart. Assessment will be made using non-specific questions 
such as ‘How do you feel?’. Specific questions will be asked wherever necessary in order to 
more precisely describe an AE.
A careful written record of all AEs shall be kept by the Investigator in charge of the trial. 
Records of AEs shall include data on the time of onset, end time, and intensity of the event as 
well as any treatment or action required for the event and its outcome.
The following must be collected and documented on the appropriate CRF(s) by the 
Investigator:
∃
From signing the informed consent onwards through the residual effect period (REP), 
until an individual subject’s end of trial: 
o
All AEs (serious and non-serious) and all AESIs.
o
The only exception to this rule are AEs (serious and non-serious) and AESIs 
in Phase I trials in healthy volunteers, when subjects discontinue from the trial 
due to screening failures prior to administration of any trial medication. In

these cases, the subjects’ data must be collected at trial site but will not be 
entered in the CRF or trial database and will not be reported in the CTR.
∃
After the individual subject’s end of trial: 
o
The Investigator does not need to actively monitor the subject for AEs but 
should only report relevant SAEs and relevant AESIs of which 
 may 
become aware of.
The REP for BI 730357, when measurable drug levels or PD effects are still likely to be 
present after the last administration, is not known for this first-in-human trial. Therefore, all 
AEs reported until the end of trial examination (last per protocol contact) will be considered 
on treatment; please see Section 7.3.3.
AE reporting to Sponsor and timelines
The Investigator must report SAEs, AESIs, and non-serious AEs which are relevant for the 
reported SAE or AESI, on the BI SAE form via fax immediately (within 24 hours of 
awareness) to the Sponsor’s unique entry point (country specific contact details will be 
provided in the ISF). The same timeline applies if follow-up information becomes available. 
In specific occasions the Investigator could inform the Sponsor upfront via telephone. This 
does not replace the requirement to complete and fax the BI SAE form.
With receipt of any further information to these events, a follow-up SAE form has to be 
provided. For follow-up information the same rules and timeline apply as for initial 
information.
Information required
For each AE, the Investigator should provide the information requested on the appropriate 
CRF pages and the BI SAE form (if applicable). The Investigator should determine the causal 
relationship to the trial medication.
The following should also be recorded as an (S)AE in the CRF and on the SAE form (if 
applicable):

Worsening of the underlying disease or of other pre-existing conditions 
∃
Changes in vital signs, ECG, physical examination and laboratory test results, if they 
are judged clinically relevant by the Investigator.
If such abnormalities already pre-exist prior trial inclusion they will be considered as 
baseline conditions.
All (S)AEs, including those persisting after individual subject’s end of trial must be followed 
up until they have resolved, have been sufficiently characterised, or no further information 
can be obtained.
5.2.3
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 (excluding 6-hour post-dose sample). 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.

To encourage compliance with alcoholic restrictions, a breath alcohol test (Alcotest® 7410, 
Dräger AG, Lübeck, Germany) will be performed prior to each treatment at time points 
indicated in the Flow Chart, and may be repeated at any time during the study at the 
discretion of an Investigator or designee. The results will not be included in the CTR.
The laboratory tests listed in Table 5.2.3: 1 and 5.2.3: 2 will be performed at 
 
 with the exception of 
the drug screening tests. These tests will be performed at the trial site using e.g. MAHSAN® -
–Kombi/DOA10 rapid test.
Laboratory data will be transmitted electronically from the laboratory to the trial site.

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

All ECGs will be stored electronically on the Muse CV Cardiology System (GE Medical 
Systems, Freiburg, Germany). Electrode placement will be performed according to the 
method of Wilson, Goldberger and Einthoven modified by Mason and Likar (hips and 
shoulders instead of ankles and wrists). Precise electrode placement will be marked with an 
indelible mark on the skin to allow reproducible placement throughout the study.
ECGs will be recorded as single ECGs or as triple ECGs (three single ECGs recorded within
180 sec) as indicated in the Flow Chart. 
All locally printed ECGs will be evaluated by the Investigator or a designee.
ECGs may be repeated for quality reasons (like alternating current artefacts, muscle 
movements, electrode dislocation). For time points with triple ECGs, all three single ECGs 
will be repeated. For the repeats due to quality reasons, only the repeated ECG recordings 
will be sent to the central ECG lab, whereas the initially recorded ECGs will be discarded. 
Additional (unscheduled) ECGs may be collected by the Investigator for safety reasons. 
These ECGs are assigned to the prior scheduled time point. Unscheduled ECGs will not be 
included into the statistical analysis of interval lengths. 
For the inclusion or exclusion (see Section 3.3) of a subject and for the assessment of cardiac 
safety during the study, the QT and QTcB values generated by the ECG machines or their 
manual corrections by the Investigators will be used. In doubtful cases, ECGs may be sent 
upfront for centralised evaluation (see below). In this case, these centrally measured results 
would overrule any other results obtained.
Abnormal findings will be reported as AEs (during the trial) or baseline conditions (at 
screening) if judged clinically relevant by the Investigator. Any ECG abnormalities will be 
monitored carefully and, if necessary, the subject will be removed from the trial and will 
receive the appropriate medical treatment.

Assessed ECGs will comply with the ICH E14 guidance document and supplements [R05-
2311, R13-0801, R13-4095] as well as the FDA requirements for annotated digital ECGs 
[R09-4830].
5.2.4.2
Continuous ECG monitoring
Cardiac rhythm (including heart rate) will be monitored during the SRD part by means of 
continuous 3-lead ECG recording for at least 15 min before (for baseline assessment) and 6 h 
following drug administration using patient monitors (e.g. Carescape B450, GE Healthcare
GmbH, Freiburg, Germany). Abnormal findings will be recorded as AEs if judged clinically 
relevant by the Investigator but no other data will be transferred to the database.
5.2.5
Assessment of other safety parameters
5.2.5.1
Vital signs
Systolic and diastolic blood pressures (BP) as well as pulse rate (PR) will be measured by a 
blood pressure monitor (Dinamap Pro 100, 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.
5.2.5.2
Medical examinations
At screening, the medical examination will include demographics including height and body 
weight, smoking and alcohol history, relevant medical history and concomitant therapy, 
review of inclusion and exclusion criteria, review of vital signs (BP, PR), 12-lead ECG
(including rhythm strip of at least 15 minutes), laboratory tests, and a physical examination. 
At the end of trial examination, it will include review of vital signs, 12-lead ECG, laboratory 
tests, and a physical examination.
5.3
OTHER
5.3.1
Pharmacogenomic evaluation
Pharmacogenomic investigations explore the role of genetic variation in determining an
individual’s response to drugs. For this purpose, a sample of at most 10 mL of blood will be 
taken at the screening examination from each subject whose genotype has not been 
previously determined. Separate informed consent for genotyping will be obtained from each 
volunteer prior to sampling.
DNA will be extracted from the blood sample in order to sequence genes coding for proteins 
that are involved in the absorption, distribution, metabolism, and excretion (ADME) of drugs. 
The gene sequences to be determined include known and likely functional variations of key 
ADME genes and incorporate more than 90% of ADME-related genetic markers identified by 
the PharmaADME group (weblink.pharmaadme.org). It is not intended to include the
pharmacogenomic data in the final report. However, the data may be part of the report if 
necessary.

APPROPRIATENESS OF MEASUREMENTS
All measurements performed during this trial are standard measurements and will be 
performed in order to monitor subjects’ safety and to determine pharmacokinetic parameters 
and biomarkers in an appropriate way. The scheduled measurements will allow monitoring of
changes in vital signs, standard laboratory values, and ECG parameters that might occur as a 
result of administration of trial medication. The safety assessments are standard, are accepted 
for evaluation of safety and tolerability of an orally administered drug, and are widely used in 
clinical trials. The pharmacokinetic parameters and measurements outlined in Section 5.5 are 
generally used assessments of drug exposure. The biomarkers and measurements outlined in 
Section 5.6 are of exploratory nature only.
5.5
DRUG CONCENTRATION MEASUREMENTS AND 
PHARMACOKINETICS
Exact time points of plasma sampling will be derived from the study management system 
ClinBase™ and documented in the CRFs by the medical personnel or sent as electronic files
to the trial data manager. The actual sampling times will be used for determination of 
pharmacokinetic parameters.
PK sampling times and periods may be adapted during the trial based on information 
obtained during trial conduct (e.g. preliminary PK data) including addition of samples and 
visits as long as the total blood volume taken per subject does not exceed 500 mL. Such 
changes would be implemented via non-substantial CTP Amendments.
5.5.1
Pharmacokinetic endpoints
The following pharmacokinetic endpoints will be determined if feasible:
5.5.1.1
Secondary endpoints
∃
AUC0-∞(area under the concentration-time curve of the analyte in plasma over the 
time interval from 0 extrapolated to infinity)
∃

5.5.2
Methods of sample collection
5.5.2.1
Plasma sampling for pharmacokinetic analysis
For quantification of BI 730357 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 90 min, with interim storage of blood samples on crashed ice between blood collection 
and centrifugation. For each aliquot the time when the sample was placed in the freezer will 
be documented. Until transfer on dry ice to the analytical laboratory, the aliquots will be 
stored upright at about -20°C or below at the trial site. The second aliquot will be transferred 
to the analytical laboratory after the bioanalyst has acknowledged safe arrival of the first 
aliquot. At the analytical laboratory the plasma samples will be stored at about -20°C or 
below until analysis.
At a minimum, the sample tube labels should list the following information: BI trial number, 
subject number, visit, and planned sampling time. Further information such as matrix and 
analyte may also be provided. 
After completion of the trial the plasma samples may be used for further methodological 
investigations, e.g. for stability testing, assessment of metabolites. However, only data related 
to the analyte and/or its metabolite(s) including anti-drug antibodies (if applicable) will be 
generated by these additional investigations. The study samples will be discarded after 
completion of the additional investigations but not later than 5 years upon the final study 
report has been signed.

5.5.2.2
Plasma sampling for metabolism analysis
Additional K3-EDTA plasma samples for the identification of drug metabolites will be 
investigated in the 25 mg dose group. Based on the knowledge gained during the trial 
conduct, e.g. from preliminary PK results, the dose group may be changed. The change will
be implemented via a non-substantial CTP Amendment.
The blood samples will be drawn in parallel to PK samples on Days 1 to 5 of the SRD part 
(see Flow Chart). At each of these time points, 2.7 ml blood will be needed for metabolite 
analysis. Apart from the storage temperature (see below) the blood samples will be processed 
in the same way as the PK samples described in Section 5.5.2.1. 
Two plasma aliquots will be obtained and stored in polypropylene cryotubes. The first aliquot 
(labelled as MIST-1 samples), should contain at least 0.5 mL of plasma. The remaining 
plasma will be the second aliquot (labelled as MIST-2 samples). The process from blood 
collection to the transfer of plasma aliquots into the freezer should be completed within 
90 min, with interim storage of blood samples on crashed ice between blood collection and 
centrifugation. Until transfer on dry ice to the metabolism laboratory, the aliquots will be 
stored at the trial site. Samples will be positioned upright and will be frozen at approximately 
-70°C. The second aliquot will be shipped to the metabolism laboratory after the metabolism 
scientist has acknowledged safe arrival of the first aliquot. At the metabolism laboratory, the 
plasma samples will be stored at about -70°C until analysis.
At a minimum, the sample tube labels should list the following information: BI trial number, 
subject number, visit, planned sampling time and ‘MIST-1 or ‘MIST-2’. Further information 
such as matrix and analyte may also be provided. 
Plasma samples dedicated to metabolism investigation are transferred to:

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 are to be performed and completed within a 3 h-period prior to the 
trial drug administration (including blank values for PK and biomarkers).
Starting from 72 h post administration a deviation from the scheduled time for PK and 
biomarker sampling of ±70 min is acceptable.
The acceptable deviation from the scheduled time for vital signs, ECG and laboratory tests 
will be ± 15 min for the first 6 h after trial drug administration and ± 30 min thereafter.
Starting from 72 h post administration a deviation from the scheduled time for vital signs, 
ECG and laboratory tests of ±70 min is acceptable.
If scheduled in the Flow Chart at the same time as a meal, blood sampling, vital signs and 
12-lead ECG recordings have to be done first. Furthermore, if several measurements 
including venipuncture are scheduled for the same time, venipuncture should be the last of 
the measurements due to its inconvenience to the subject and possible influence on 
physiological parameters.
For planned individual plasma concentration sampling times and urine collection intervals 
refer to the Flow Chart. While these nominal times should be adhered to as closely as 
possible, the actual sampling times will be recorded and used for determination of 
pharmacokinetic parameter.
If a subject misses an appointment, it will be rescheduled if possible. The relevance of 
measurements outside the permitted time windows will be assessed no later than at the 
Blinded Report Planning Meeting.
6.2
DETAILS OF TRIAL PROCEDURES AT SELECTED VISITS
6.2.1
Screening period
After having been informed about the trial, all subjects will 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 periods
Study participants will be admitted to trial site at least 1 hour prior to administration of the 
trial medication. They will be kept under close medical surveillance for at least 24 hours 
following drug administration. Thereafter the subjects will be allowed to leave the trial site 
after formal assessment and confirmation of their fitness. Afterwards the study will be 
performed in an ambulatory fashion until the end-of-study examination.
For DGs 1-7 and 10 of the SRD part, each subject will receive one dose of the respective trial 
medication (BI 730357 or placebo) at visit 2. In DGs 8 and 9 of the SRD part, the same 
subjects will be included and each subject will be treated with the same trial medication 
(either always active or always placebo), i.e. they will receive the respective trial medication 
at first in DG 8 (Visit 2) following a standard continental breakfast and in DG 9 (Visit 3) 
following a high-fat breakfast. The treatments of DG 8 and DG 9 are separated by a wash-out 
phase of at least 14 days between each drug administration.
The participants of the BA part will receive the respective trial medication (BI 730357) at 
visit 2, 3 and 4. Details on treatments and procedures of administration are described in 
Section 4.1.4.
For details on time points and procedures for collection of plasma and urine samples for PK 
analysis, refer to Flow Chart and Section 5.5.2. 
The safety measurements performed during the treatment period are specified in Section 5.2. 
of this protocol and in the Flow Chart. For details on time points for all other trial procedures, 
refer to the Flow Chart. AEs and concomitant therapy will be assessed continuously from 
screening until the end of trial examination.
6.2.3
End of trial period 
For AE assessment, laboratory tests, recording of ECG and vital signs, and physical 
examination during the end of trial period, see Sections 5.2.2 to 5.2.5.
Subjects who discontinue treatment before the end of the planned treatment period should 
undergo the end of trial visit.
All abnormal values (including laboratory parameters) that are judged clinically relevant by 
the Investigator will be monitored using the appropriate tests until a return to a medically 
acceptable level is achieved. (S)AEs persisting after subject’s end of trial must be followed 
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
SRD Part:
The primary objective of the first (SRD) part of this trial is to investigate the safety and 
tolerability of BI 730357 by using descriptive statistics for all endpoints comparing active 
dose groups to placebo. The primary endpoint is defined in Section 5.2.1. Inferential statistics 
is not planned (as explained in Section 7.2).
The secondary objective is the exploration of the pharmacokinetics (PK) of BI 730357. 
Endpoints as specified in 5.5.1 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.
BA Part:
The primary objective of the second part of the study is to investigate relative bioavailability 
of 25 mg BI 730357 as oral solution (Test 1, T1) and 25 mg BI 730357 given as tablet after a 
standardised high-fat breakfast (Test 2, T2), each compared to 25 mg BI 730357 as tablet in a 
fasting state (Reference, R)
The secondary objective is the evaluation and comparison of several PK parameters between 
the treatments. The secondary objectives will be assessed by descriptive statistics.
7.1.2
Endpoints
The primary endpoint to describe safety and tolerability of BI 730357 will be the number (% 
subjects) with drug-related AEs. The collection of parameters pertaining to these 
investigations is described in detail in Section 5.2.1.
The secondary pharmacokinetic endpoints to be used for the assessment of dose 
proportionality and relative bioavailability are specified in Section 5.5.1.1.
7.1.3
Model
SRD part:
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. 
The model consists of a regression model applied to log-transformed data under fasting 
conditions. The corresponding ANCOVA model includes the logarithm of the dose as a 
covariate.

Together with 
and 
, taking natural logarithms converts this model 
to a linear form as follows:
where
logarithm of the pharmacokinetic endpoint for subject j at dose level i; 
where i = 1, 2, …, 7, j = 1, 2, …, 8;
) 
intercept parameter;
slope parameter;
logarithm of dose i;
random error associated with subject j at dose level i (assumed to be 
independent and identically normally distributed).
This equation can be fit as a linear regression model. Based on the estimate for slope 
parameter (β), a 2-sided 95% CI for the slope will be computed. Perfect dose proportionality 
would correspond to a slope of 1. The assumption of a linear relationship between the log-
transformed pharmacokinetic endpoint and the log-transformed dose will be checked.
If dose proportionality over the entire dose range investigated cannot be shown, an attempt 
will be made to identify dose range(s), where dose proportionality can be assumed.
BA part: Investigation of relative bioavailability
Relative bioavailability is primarily to be determined on the basis of the parameters AUC0-∗
and Cmax (cf. Section 5.5). Those parameters will be ln-transformed (natural logarithm) prior 
to fitting the model.
The statistical model used for the analysis of AUC0-∗and Cmax will be an ANOVA (analysis 
of variance) model on the logarithmic scale.  This model will include effects accounting for 
the following sources of variation: ‘sequence’, ‘subjects within sequences’, ‘period’ and 
‘treatment’. The effect ‘subjects within sequences’ will be considered as random, whereas the 
other effects will be considered as fixed. For tests on subject, period, and treatment effects, 
the denominator sum of squares will be the sum of squares for error; while for tests on 
sequence effects, the denominator will be the sum of squares for subjects. The model is 
described by the following equation
yijkm = + + ,i + sim + −j + .k + eijkm,  where
yijkm = logarithm of response (endpoint, see Section 7.1.3) measured on subject m in 
sequence i receiving treatment k in period j,
+ = the overall mean,

eijkm = the random error associated with the mth subject in sequence i who received

The difference between the expected means for test treatments and reference treatment 
log(Ti)-log(R), i=1,2, will be estimated by the difference in the corresponding Least Square 
Means (point estimate) and two-sided 90% confidence intervals based on the t-distribution 
will be computed. These quantities will then be back-transformed to the original scale to give 
the point estimator (geometric mean) and interval estimates for the ratio between response 
under test and response under reference.
Pairwise comparisons will be done for:
•
Oral solution (PfOS) fasted (Test 1/T1) vs tablet fasted (Reference)
•
Tablet fed (Test 2/T2) vs tablet fasted (Reference)
7.2
NULL AND ALTERNATIVE HYPOTHESES
Safety and tolerability of different dose groups of BI 730357 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.
In the SRD part, for the evaluation of dose proportionality, a two-sided 95% confidence 
interval (CI) of the slope will be computed. However, the CI will have to be interpreted in the 
perspective of the exploratory character of the study, i.e. as interval estimate for effects in the 
present data.
The relative bioavailability of BI 730357 will be estimated by the ratios of the geometric 
means (test/reference) for the secondary PK 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 on testing, an acceptance 
range was not specified, that is, no hypothesis will be tested.

corporate procedure of the Sponsor ‘Standards and processes for analyses performed within 
Clinical Pharmacokinetics/Pharmacodynamics’ (001-MCS-36-472, current version). 
Pharmacokinetic parameters of a subject will be included in the analysis unless the subject 
has an important protocol violation relevant for the evaluation. Whether a protocol violation 
is important will be decided no later than in the Report Planning Meeting. 
Reasons for exclusion of single pharmacokinetic parameters may be:
∃
The subject experiences emesis at or before two times median tmax. Median tmax is to 
be determined for the test product excluding the subjects experiencing emesis.
∃
The subject experiences emesis at any time during the labelled dosing interval.
∃
Time deviations
∃
Use of restricted medications 
The subject set for the evaluation of PK endpoints (PKS) will include all treated subjects that 
provide at least one observation for at least one primary endpoint without important protocol 
violations with respect to the statistical evaluation of PK endpoints. It will also be decided in 
the Report Planning Meeting which subjects are to be included in the PKS. 
Excluded subjects will be listed with their individual plasma concentrations and individual 
pharmacokinetic parameters, however, will not be included in descriptive statistics for plasma 
concentrations, pharmacokinetic parameters or other statistical assessment.
SRD Part: Assessment of dose proportionality
Dose proportionality of the secondary pharmacokinetic endpoints under fasting conditions 
will be explored based on the regression model described in Section 7.1.3. Based on the 
estimate for slope parameter ((), a 2-sided 95% CI for the slope will be computed. Perfect 
dose proportionality would correspond to a slope of 1. The assumption of a linear relationship 
between the log-transformed pharmacokinetic endpoint and the log-transformed dose will be 
checked.
If dose proportionality over the entire dose range under fasting conditions investigated cannot 
be shown, an attempt will be made to identify dose ranges, where dose proportionality can be 
assumed.
BA Part: Assessment of relative bioavailability
Point estimates of bioavailability, the ratios of the geometric means (test/reference) for the 
secondary endpoints (see 5.5.1.1), and their two-sided 90% CIs will be provided.
To this end, the PK endpoints will be log transformed (natural logarithm) prior to fitting the 
ANOVA model (cf. Section 7.1.3). For each endpoint, the difference between the expected 
means for log(Ti)-log(R) will be estimated by the difference in the corresponding adjusted 
means (LeastSquares Means), and a two-sided 90% confidence interval based on the 
t-distribution will be computed. These quantities will then be back-transformed to the original 
scale to provide the point estimate and 90% CIs for each endpoint.

7.3.3
Safety analyses
Safety analyses will be performed in accordance with BI standards. 
All treated subjects (that is, all subjects who received at least one dose of study drug), will be 
included in the safety evaluation. Safety analyses will be descriptive in nature and will be 
based on BI standards.
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. 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 ‘treatment at onset’. 
Measurements (such as ECG, vital signs, or laboratory parameters) or AEs will be assigned to 
treatments (see Section 4.1) based on the actual treatment at the planned time of the 
measurement or on the recorded time of AE onset (concept of treatment emergent AEs). 
Therefore, measurements planned or AEs recorded prior to first intake of trial medication will 
be assigned to 'screening', those between first trial medication intake until the end of trial visit 
will be assigned to the treatment period, and those after the end of trial examination will be 
assigned to ‘post-study’. These assignments including the corresponding time intervals will 
be defined in detail in the TSAP.
Additionally, further treatment intervals (analysing treatments) may be defined in order to 
provide summary statistics for time intervals, such as combined treatments, on-treatment 
totals or periods without treatment effects (such as screening and post-study intervals). 
Adverse events will be coded using the Medical Dictionary for Regulatory Activities
(MedDRA). Frequency, severity and causal relationship of AEs will be tabulated by 
treatment, system organ class and preferred term. SAEs, AESIs (see Section 5.2.2.1) and 
other significant AEs (according to ICH E3) will be listed separately. 
Laboratory data will be compared to their reference ranges. Values outside the reference 
range as well as values defined as clinically relevant will be highlighted in the listings. 
Additionally, differences from baseline will be evaluated.
Vital signs or other safety-relevant data observed at screening, baseline, during the course of 
the trial and at the end-of-trial evaluation will be assessed with regard to possible changes 
compared to findings before start of treatment.
A centralised evaluation of all 12-lead ECGs recordings (see Section 5.2.4) will be the basis 
for the derivation of further ECG parameters based on the ECG variables 
 
. The baseline value of an ECG variable is defined as the mean of 
the triple ECG measurements prior to drug administration. The derivation of the quantitative 
and qualitative ECG endpoints and their analyses will be described in the TSAP.

7.3.4
Preliminary PK analyses
A preliminary analysis of PK parameters (AUC0-24 and Cmax of BI 730357) provided as 
individual values and geometric means of at least the first cohort per dose level, will be 
performed for 
∃
all dose levels up to n-2 before proceeding to dose level n (with n ≤50 mg)
∃
all dose levels up to n-1 before proceeding to dose level n (with n > 50 mg)
(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 were available)
A preliminary analysis of pharmacodynamic biomarkers is not planned.
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 preliminary data on safety, tolerability, changes of dosing schedule (e.g. 
additional intermediate doses) or planned times for PK/biomarker-sampling, additional 
preliminary PK-analysis may be performed based on the request of the trial clinical monitor, 
the Investigator, or trial clinical pharmacokineticist. Preliminary PK data will be distributed 
to the Investigator. No formal interim report will be written.
No inferential statistical preliminary analysis is planned. However, after each dose group the 
Investigator (or 
 deputy) is allowed to postpone further dose progression until a 
preliminary analysis of the data already obtained has been performed.
7.3.5
Pharmacokinetic analyses
The pharmacokinetic parameters listed in Section 5.5.1 for drug BI 730357 will be calculated 
according to the BI SOP ‘Standards and processes for analyses performed within Clinical 
Pharmacokinetics/Pharmacodynamics’ (001-MCS-36-472).
Subjects who are not included in the PKS (refer to Section 7.3.1.) will be reported with their 
individual plasma / urine concentrations and individual pharmacokinetic parameters; 
however, they will not be included in descriptive statistics for plasma / urine concentrations, 
pharmacokinetic parameters.
Only concentration values within the validated concentration range and actual sampling times 
will be used for the calculation of pharmacokinetic parameters. Concentrations used in the 
pharmacokinetic calculations will be in the same format provided in the bioanalytical report, 
(that is, to the same number of decimal places provided in the bioanalytical report).
If a predose concentration value is greater than 5% of Cmax, the subject’s pharmacokinetic 
data will be not included in any statistical evaluations, in accordance with international 
guidances. The individual pharmacokinetic parameters of such a subject will be calculated 
and listed separately. If a predose concentration is above BLQ, but less than or equal to 5% of

the subject’s Cmax value, the subject’s data without any adjustments will be included in all 
pharmacokinetic measurements and calculations.
Every effort will be made to include all concentration data in an analysis. If not possible, a 
case to case decision is required whether the value should only be excluded from half-life 
estimation or the complete analysis. 
∃
If a concentration is only excluded from half-life determination, it will be used for all 
other calculations (e.g. descriptive statistics) and for graphical presentation.
∃
If a concentration value is excluded from all calculations, it will not be presented 
graphically or used for the calculation of descriptive statistics and parameter 
determination. However the excluded concentration itself will be listed in the clinical trial 
report associated with an appropriate flag.
Descriptive statistics of parameters are calculated only when at least 2/3 of the individual 
parameter estimates of a certain parameter are available. If the actual sampling time will not 
be recorded or will be missing for a certain time point, the planned time will generally be 
used for this time point instead. Pharmacokinetic parameters which cannot be determined will 
be identified by "not calculated" (NC).

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 drug concentration - time profiles
Handling of missing PK data will be performed according to the relevant SOP of the Sponsor 
(001-MCS-36-472).
Drug concentration data identified with NOS (no sample available), NOR (no valid result), 
NOA (not analysed), BLQ (below the lower limit of quantification), or NOP (no peak 
detectable) will be displayed as such and not replaced by zero at any time point (this rule also 
applies also to the lag phase, including the predose values).

For the non-compartmental analysis, concentration data identified with NOS, NOR or NOA 
will generally not be considered. Concentration values in the lag phase identified as BLQ or 
NOP will be set to zero. All other BLQ/NOP values of the profile will be ignored. The lag 
phase is defined as the period between time zero and the first time point with a concentration 
above the quantification limit.
7.5
RANDOMISATION
SRD part: Each dose group will be divided into two cohorts. The subjects of the first cohort 
will not be randomised to maintain a treatment sequence of active-placebo-active-active due 
to safety reasons. In the second cohort of each dose level the subjects will be assigned to 
active or placebo treatment using a 3:1 allocation ratio. 
BA part: Subjects will be randomized to one of the six treatment sequences R/T1/T2, 
R/T2/T1, T1/T2/R, T1/R/T2, T2/T1/R, T2/R/T1 in a 1:1:1 ratio. 
The Sponsor will arrange for the randomisation as well as packaging and labelling of trial 
medication. The randomisation list will be generated using a validated system, which 
involves a pseudo-random number generator and a supplied seed number so that the resulting 
allocation is both reproducible and non-predictable. 
The randomisation list will contain additional blocks to allow for subject replacement (refer 
to 3.3.5).
7.6
DETERMINATION OF SAMPLE SIZE
SRD part
It is planned to include a total of 72 subjects in this study part. The planned sample size is not 
based on a power calculation. The size of 8 subjects per dose group (6 on active treatment, 
and 2 on placebo) is commonly used in single-rising dose studies of the present type and is in 
general considered as sufficient for the exploratory evaluation of single dose safety and 
pharmacokinetics [R95-0013].
BA part
It is planned to enter 12 subjects in this trial part, because this sample size is considered 
sufficient to achieve the aims of this exploratory trial.
With this sample size, the following precision of the ratio of geometric means (test/reference)
can be expected. Precision is defined as the ratio of upper to lower confidence interval limit.
Note that the precision is independent of the actual ratio of geometric means. For this First-
in-Man trial, no information on intra-subject variability is available. Therefore, Table 7.6: 1
provides an overview on the achievable precision for estimating the ratio of geometric means 
(test/reference) for three different gCV. For illustrative purposes, the expected 90% 
confidence intervals with 95% coverage probability are displayed for different values of 
geometric means ratios T/R in the three-period three-sequence crossover design.

CRFs for individual subjects will be provided by the Sponsor. For drug accountability, refer 
to Section 4.1.8.
ClinBaseTM
In the Human Pharmacology Centre – Boehringer Ingelheim's Phase I unit the validated 
ClinBaseTM system is operated for processing information and controlling data collected in 
clinical studies. In addition to its function as a procedure control system, ClinBaseTM serves 
as data base. Instead of being entered into CRFs, selected data are directly entered into the 
system.
8.3.1
Source documents
Source documents provide evidence for the existence of the subject and substantiate the 
integrity of the data collected. Source documents are filed at the Investigator’s site.
All data reported in the CRFs must be consistent with the source data or the discrepancies 
must be explained.
Data directly entered into ClinBaseTM (that is, without prior written or electronic record) are 
considered to be source data. The place where data is entered first will be defined in a trial 
specific Source Data Agreement. The data in ClinBaseTM are available for inspection at any 
time.
The Investigator may need to request previous medical records or transfer records, depending 
on the trial.
8.3.2
Direct access to source data and documents
The Investigator/institution will permit trial-related monitoring, audits, IRB/IEC review and 
regulatory inspection, providing direct access to all related source data/documents. CRFs and 
all source documents, including progress notes (if applicable) and copies of laboratory and 
medical test results must be available at all times for review by the Sponsor’s clinical trial 
monitor, auditor and inspection by health authorities (e.g. FDA). The Clinical Research

Description of change
1. Number of subjects in the SRD part increased 
by 16, administration of 400 mg and 800 mg
BI 730357 or placebo under fed conditions 
added, option for additional subjects removed 
2. Visit 3 and standard breakfast added 
3. Preliminary clinical data on safety, tolerability 
and PK from the SRD and BA part presented
4. 800 mg dose added, paragraph to ‘maximum 
dose and dose escalation‘ amended 
5. Fasting conditions specified for SRD part
6. Update on observed half-life
7. Number of subjects increased, option for 
additional subjects removed, 3 additional dose 
groups (DGs) added in Table 3.3:1
8. No replacement for DGs 8, 9 and 10
9. Number of subjects increased, option for 
additional subjects removed
10. DGs 8-10 added; maximum dose and number 
of dose cohorts adapted, DGs 8-10 added in 
Table 4.1.4: 1, high-fat breakfast and 
continental breakfast added in the SRD part, 
composition of standard continental breakfast 
added (Table 4.1.4:4)
11. Treatments periods of DGs 8-9 described
12. Investigation of dose proportionality under 
fasting conditions only
13. Investigation of dose proportionality under 
fasting conditions only
14. Number of subjects in the SRD part increased
Rationale for change
The highest exposures observed in this trial after 
the 400 mg dose under fasting conditions (Cmax of 
755 nM, AUC0-24 of 9,453 nM*h) are significantly 
below the predicted exposures at 400 mg (Cmax of 
2,547 nM and AUC0-24 of 42,458 nM*h) and the 
acceptable exposure limit of this trial (Cmax of 
5,920 nM, and AUC0-24 of 132,400 nM*h). Since 
we observed a 36% increase in exposure in the fed 
versus fasted condition, it is planned to investigate 
3 additional DGs in the fed condition to further 
evaluate safety and PK of higher BI 730357 
exposures, including the influence of food (normal 
and high-fat diet) on higher doses. The results will 
support the testing of higher exposures during the 
planned multiple-rising dose trial and further 
clinical development.
