INTRODUCTION
1.1
MEDICAL BACKGROUND
Retinoic acid related orphan receptor γt (RORγt) is a nuclear hormone receptor/transcription 
factor expressed in Th17 cells and in distinct subsets of lymphoid cells, including natural 
killer (NK) cells, innate lymphoid cells (ILC), and γδT cells. RORγt sits at a key focal point, 
integrating multiple signals, including T cell receptor engagement and cytokines (e.g., IL-1, 
IL-6, IL-23), and driving the expression of multiple genes (e.g., IL-17A, IL-17F, IL-22, IL-
23R). Via sitting at this focal node integrating multiple signals and effecting multiple outputs, 
RORγt has the potential
 
Boehringer Ingelheim (BI) is developing the new chemical entity (NCE),
 
BI 730357, for the treatment of patients 
and other 
 
diseases. BI 730357 binds 
. By integrating multiple activating 
 
signals and via blocking the transcription of multiple key 
effector 
 BI 730357 has the potential to be 
as or more efficacious than 
 agents in the treatment of 
-related disease indications.

DRUG PROFILE
Nonclinical pharmacology
1.2.1
BI 730357 was profiled in cellular assays in primary human cells central to the pathogenesis 
underlying 
 BI 730357 
provided consistent potency across all stimuli, cell types, and species tested, including  
conditions. BI 730357 provided substantial inhibition of disease-relevant 
biomarker and histology reads in mechanistic 
 models 
 
BI 730357 showed good 
 in that it exhibited 
 and 
only low-level

 and 
low-level 
 No other

Toxicology
1.2.2
The toxicity profile of BI 730357 has been assessed in safety pharmacology, genetic toxicity, 
embryo-fetal development and repeat dose toxicity studies up to 26- and 39-weeks
 
 respectively. In general, BI 730357 appears to be well tolerated at clinically-relevant 
plasma exposures in toxicity studies. Effects on the gastrointestinal tract (emesis/vomitus 
and/or soft stool) and/or decreased food consumption associated with adverse decreases in 
body weight were seen
(which achieved 
 the anticipated human therapeutic exposure 
). In the 39-week study, at

for reversibility. In the 4- and 13-week studies 
 no stomach inflammation was seen at 
doses 
 however gastrointestinal effects such as emesis/vomitus and 
decreased food consumption and body weight were seen. As similar gastro-intestinal effects 
were seen in the 39-week study 
 the microscopic stomach inflammation 
may be preceded by clinically-notable effects on the gastrointestinal tract.

Clinical experience in humans
1.2.5
The Phase Ia, first-in-human, single-rising-dose (SRD) trial 1407.1 was completed.
BI 730357 has been administered to 54 healthy male subjects as a single dose, while 18 
subjects received placebo. An additional 12 subjects were treated with 3 individual doses of 
BI 730357 consecutively. The overall frequency of subjects with treatment-emergent adverse 
event (AE) was higher for subjects who received BI 730357 (7.4%) than for subjects who 
received placebo (5.6%), however no dose-dependency was evident, nor were differences 
observed among treatments in a bioavailability substudy. The most frequent of these was 
headache in 5.6% subjects receiving BI 730357 and in 5.6% in subjects receiving placebo.
The only other drug-related AE was oropharyngeal pain, reported for 1 subject receiving 
BI 730357. AEs generally reflected commonly-occurring events of short duration, were
mostly mild or moderate in severity, and were distributed without discernable trend among 
recipients of placebo and rising dose levels of BI 730357. There were no serious adverse 
events (SAE) reported. Overall, BI 730357 was well tolerated.
Preliminary safety data for recently-completed Phase Ib multiple-rising-dose trial 1407-0002 
indicate that with respect to the kind, incidence and severity of the AEs, there were no 
notable differences among dose groups. No SAEs were reported during the trial. ECG 
recordings, clinical laboratory evaluation, and vital signs showed no clinically-relevant 
changes compared to baseline. Overall, administration of BI 730357 to healthy male subjects 
at doses up to 400 mg for up to 28 days was well tolerated.
In SRD trial 1407.1, exposure to BI 730357 increased in a dose-proportional manner for 
solution between 2 and 8 mg and for tablet up to 50 mg, and thereafter increased in a less-
than-dose-proportional manner, with approximately 1.5-fold increase in exposure with each 
2-fold increase in dose up to 400 mg in the fasted state. Bioavailability of the 25 mg tablet 
fasted was less than that of the 25 mg solution fasted. There was
 greater exposure 
following administration of the 25 mg tablet under fed than fasted conditions, suggesting a 
positive food effect for BI 730357. BI 730357 was also administered at 400 mg and 800 mg 
under fed conditions (following standardized continental and high-fat breakfasts) to further 
evaluate the safety and PK of higher BI 730357 exposures. These results show that exposures 
continue to increase at higher doses with food, suggesting a positive food effect.
In Phase Ib trial 1407-0002, preliminary PK data indicate that exposure appears to increase in 
an approximately dose-proportional manner from 25 mg to 100 mg dose after repeat oral 
dosing of BI 730357 in the fasted state, and in a less-than dose-proportional manner from the 
100 mg to 200 mg dose.

Accumulation of BI 730357 was approximately 2-fold from single dose to steady state for all 
dose groups.

RATIONALE FOR PERFORMING THE TRIAL
This Phase I study is to investigate the safety, tolerability, and PK of BI 730357, in order to 
understand the clinical safety and pharmacokinetic profile in healthy male Japanese subjects 
after single-rising oral doses of BI 730357 within the dose range to be evaluated in further 
clinical studies with BI 730357 in the indication 
.
Japanese healthy male subjects aged 20 to 45 years will be recruited for this study. This 
population is expected to provide a relatively stable physiological, biochemical, and 
hormonal basis (steady state) for studying drug effects, and to show no disease-related 
variation, and is not expected to use concomitant medication. 
Within each dose group, all actively-treated individuals will receive the same BI 730357 
dose. The next higher dose will only be administered (to the next group) if the treatment in 
the preceding dose groups was safe and showed acceptable tolerability. BI 730357 dose 
levels evaluated in this trial have been previously evaluated in first-in-human trial 1407.1, the 
results of which are provided in Section 1.2.5.
Dose selection
It is intended to investigate the following dose levels of BI 730357 in this trial: 50 mg, 
100 mg, and 200 mg. The background for this dose selection is described in the following 
paragraphs.
A minimum daily dose of about 
 may be required to achieve therapeutic systemic 
exposure to BI 730357. However, higher doses might still be well tolerated while providing a 
larger magnitude of therapeutic effects. Further, testing of doses higher than 
 is also 
reasonable to compensate for any bioavailability and half-life lower than expected. Finally, 
even if the therapeutic dose is determined to be as low as 
, higher than therapeutic 
doses are typically explored Phase I studies to provide a safety margin for following studies 
e.g., drug-drug-interaction studies, studies with patients with impaired excretion function, 
etc., where substantial increases in exposure may be seen.
For this study 200 mg has been selected as the maximum dose, a dose that is expected to be 
high enough to obtain exposure in the therapeutic range, even if the bioavailability was 
significantly lower than the expected 
 (refer to Section 1.2.5). 
Non-clinical BI 730357 safety data demonstrated an acceptable profile to support clinical 
trials in males and females, including women of childbearing potential. Human exposures up 
to those achieved at the NOAEL 
 in the 4- and 13-week

 in males and females combined) are considered safe 
for dosing up to 13 weeks in clinical trials. The mean exposures after single dose 
administration 
 for the 200 mg fasting dose group in 
1407-0002 remain below this NOAEL.

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 clinical development of a 
new orally available drug, which might improve the therapy in patients 
. Subjects 
participating in this study are exposed to the risks of the study procedures and those related to 
the exposure to the trial medication.
Procedure-related risks
Blood sampling by venipuncture or through an indwelling venous catheter 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 total volume of blood withdrawn during the trial per subject will not exceed the volume 
of a normal blood donation (400 mL). No health-related risk to healthy subjects is expected 
from this blood withdrawal.
Drug-related risks and safety measures
The nature of the target and the mechanism of action of BI 730357 are well understood from 
preclinical models. The safety, tolerability, and PK exposure following single-dose 
administration of BI 730357 have already been established in first-in-human trial 1407.1, at 
dose levels up to 800 mg, 4-fold higher than the maximum dose level (200 mg) to be 
evaluated in the current trial. Furthermore, since this is not a First-in-Human trial, the risk is 
relatively lower.
The pharmacological effects of BI 730357 are dose dependent and no evidence for prolonged 
or irreversible effects has been observed. Single dose administration of dose levels up to 
800 mg BI 730357 are supported by preclinical safety data.

Extensive safety laboratory testing will be performed with special focus on full blood 
exam (refer to Flow Chart).

A thorough ECG monitoring including 4-hours continuous 3-lead ECG measurement 
for at least 15 min before drug administration (for baseline assessment) and for
4 hours following drug administration to cover the anticipated period of highest drug 
exposure, and additional repeated single 12-lead ECGs over 48 hours (during hospital
stay) following drug administration. Dose escalation would be stopped as soon as at

least 2 subjects at one dose level showed relevant QT prolongation (refer to Section 
3.3.4.3 for details).

Prior to each dose escalation, a documented safety review will be performed by the 
principal investigator and the sponsor (clinical trial leader [CTL]). For details, refer to 
Section 3.1.

Subjects will be hospitalized on Day -1 (one day before drug administration) and will 
be discharged on Day 3 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 observation and thoroughly monitored for both, expected and 
unexpected AEs.

Only if the respective dose of BI 730357 was safe and showed acceptable tolerability 
and if no stopping criterion was met (refer to Section 3.3.4.3), the next higher dose 
will be given at least 7 days later (referring to the 1st subject of each dose group).
Since preclinical data indicate that BI 730357 has potential for phototoxicity, subjects will be 
advised to apply protection measures such as sunscreen, and solarium radiation are prohibited 
during this clinical trial until the end of the respective follow-up period.
BI 730357 was determined in vitro to be a substrate, an inactivator, and an inducer of 
, as well as an inducer of 
, thus there is a potential risk of 
clinically relevant drug-drug interactions (DDI) occurring. Whether 
 substrates will 
need to be excluded/monitored in subsequent clinical trials will be determined based on 
results of planned the DDI trials.
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 5.2.6.1.4.

development program, and monitoring of peripheral blood lymphocyte subsets integrated into 
clinical trials.

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 Phase I 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 patients with PsO, 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 SRD trial is designed as double-blind, randomised within dose group, and placebo-
controlled within parallel dose groups.
A total of 24 Japanese healthy male subjects is planned to participate in the trial, according to 
3 sequential groups comprising 8 subjects per dose group. 
Within each dose group, 6 subjects will receive the active drug and 2 will receive placebo. 
Only one dose is tested within each dose group.
The dose groups to be evaluated are outlined in Table 3.1: 1 below.

The dose 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 and tolerability
data of the preceding dose groups. The next dose group will only be dose if, in the opinion of 
the investigator, no safety concerns arose in the preceding dose group(s) (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).
A documented safety review must take place prior to randomization in the next group. 
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 AEs, 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 sponsor. 
The minimum data set for review consists of the following data:

AEs in the current and preceding dose group(s) (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 4-hours continuous 3-lead ECG monitoring in the 
current and preceding dose groups.


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 sponsor after in-depth analysis of all available safety data, 
especially SAEs (if any), AEs, and out-of-range laboratory results (if considered clinically 
significant). Safety reviews can be conducted verbally (e.g., teleconference) and/or in writing 
(e.g., encrypted emails, facsimiles correspondences or mails). The CTL 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 investigator site file (ISF) and trial 
master file (TMF).
An overview of all relevant trial activities is provided in the Flow Chart. For visit schedules 
and details of trial procedures at selected visits, refer to Sections 6.1 and 6.2, respectively.
3.2
DISCUSSION OF TRIAL DESIGN, INCLUDING THE CHOICE OF 
CONTROL GROUP
For SRD trials, the design described in Section 3.1 is viewed as 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.
With the rising dose design, double-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. 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. Six subjects per active treatment group are in general considered 
as sufficient for the exploratory evaluation of pharmacokinetics. 
3.3
SELECTION OF TRIAL POPULATION
It is planned that 24 Japanese healthy male subjects will enter the study. Subjects will be 
recruited at the trial site.
Only male subjects will be included into the study.
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.

Withdrawal of subjects from treatment or assessments
3.3.4
Subjects may discontinue trial treatment or withdraw consent to trial participation as a whole 
(‘withdrawal of consent’) with very different implications; please refer to Section 3.3.4.1 and 
3.3.4.2 below.
If a subject is removed from or withdraws from the trial prior to the first administration of 
trial medication, the data of this subject will not be entered in the case report form (CRF) and 
will not be reported in the clinical trial report (CTR). If a subject is removed from or 
withdraws from the trial after the first administration of trial medication, this will be

documented and the reason for discontinuation must be recorded in the CRF; in addition, the 
data will be included in the CRF and will be reported in the CTR.
At the time of discontinuation, a complete end of study examination will be performed, if 
possible, and the information will be recorded in the CRF. If the discontinuation occurs 
before the end of the REP (refer to Section 1.2.6), the discontinued subject should if possible 
be questioned for AEs and concomitant therapies at or after the end of the REP in order to 
ensure collection of AEs and concomitant therapies throughout the REP, if not contrary to 
any consent withdrawal of the subject.
Discontinuation of trial treatment
3.3.4.1
An individual subject will discontinue trial treatment if:
-
The subject wants to discontinue trial treatment, without the need to justify the 
decision
-
The subject has repeatedly shown to be non-compliant with important trial 
procedures and, in the opinion of both, the investigator and sponsor representative, is 
not willing or able to adhere to the trial requirements in the future 
-
The subject needs to take concomitant medication that interferes with the 
investigational medicinal product or other trial treatment
-
The subject can no longer receive trial treatment for medical reasons (such as 
surgery, AEs, or diseases)
-
An AE or clinically significant laboratory change or abnormality occurs that the 
investigator assesses as warranting not administering trial medication. This may 
include cases of sustained symptomatic hypotension (BP <90/50 mmHg) or 
hypertension (BP >180/100 mmHg), clinically relevant changes in ECG requiring 
intervention, or unexplained hepatic enzyme elevations at any time during the trial
-
The subject has an elevation of aspartate transaminase (AST) and/or alanine 
transaminase (ALT) ≥3-fold upper limit of normal (ULN) and an elevation of total 
bilirubin ≥2-fold ULN (measured in the same blood sample), an elevation of ALT 
and/or AST ≥10-fold ULN, and/or needs to be followed up according to the DILI 
checklist provided in the ISF
In addition to these criteria, the physician may discontinue subjects at any time based on his 
or her clinical judgment.
Even if the trial treatment is discontinued, the subject remains in the trial and, given his/her 
agreement, will follow up as outlined in the Flow Chart and Section 6.2.3.
Withdrawal of consent to trial participation
3.3.4.2
Subjects may withdraw their consent to trial participation at any time without the need to 
justify the decision. If a subject wants to withdraw consent, the investigator should be 
involved in the discussion with the subject and explain the difference between trial treatment 
discontinuation and withdrawal of consent to trial participation, as well as explain the options

for continued follow up after trial treatment discontinuation, please refer to Section 3.3.4.1
above.
Discontinuation of the trial by the sponsor
3.3.4.3
BI reserves the right to discontinue the trial overall or at a particular trial site at any time for 
any of the following reasons:
-
New toxicological findings or SAEs 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 AEs of moderate or severe 
intensity, or if at least one drug-related serious AE is reported that is considered to 
be unacceptable
-
The expected enrolment goals overall or at a particular trial site are not met
-
Violation of Good Clinical Practice (GCP), or the clinical trial protocol (CTP), or the 
contract with BI by a trial site or investigator, disturbing the appropriate conduct of 
the trial
-
The sponsor decides to discontinue the further development of the investigational 
product
-
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 mseconds from baseline in connection with absolute QT or QTc greater 
than 500 mseconds, which has been confirmed by a repeat ECG recording
The investigator/the trial site will be reimbursed for reasonable expenses incurred in case of 
trial termination (except in case of the third reason).
For the following scenario further enrolment randomisation into the trial and treatment of 
already randomised subjects will be interrupted by the sponsor once the sponsor becomes 
aware:

Two SAEs in two different subjects in the same system-organ-class, confirmed by both 
the investigator and sponsor as having a reasonable causal relationship to the trial 
medication administration.

Two ‘severe’ non-serious AEs in two different subjects in the same cohort, independent 
of within or not within the same system-organ-class, confirmed by both the investigator 
and sponsor as having a reasonable causal relationship to the trial medication 
administration.
Replacement of subjects
3.3.5
In case some subjects do not complete the trial, the CTL together with the trial 
pharmacokineticist and the trial statistician are to decide if and how many subjects will be

Selection of doses in the trial
4.1.2
Three dose groups are to be investigated in this trial. Three dose levels will cover potential 
therapeutic dose ranges. The number of dose levels will also allow for evaluation of dose 
proportionality.
This trial is designed to evaluate the safety, tolerability, and pharmacokinetics of BI 730357 
in Japanese healthy male volunteers. A safe and tolerable dose achieved in previous trials,
including Caucasian SRD trial (1407.1), is used as a reference for the dose selection in this 
trial. 
For safety margins and further details on dose selection, refer to Section 1.2 and 1.3.
Method of assigning subjects to treatment groups
4.1.3
Prior to the screening visit, subjects will be contacted in writing and informed about the 
planned visit dates. The subjects willing to participate will be recruited to dose groups 
according to their temporal availability. 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. 
Subjects will be assigned to treatments (active treatment or placebo) prior to the first 
administration of trial medication. For this purpose, the randomisation list will be provided to the 
trial site in advance. Subjects are then assigned to treatment according to the randomisation list.
The randomisation procedure is described in Section 7.6.
Drug assignment and administration of doses for each subject
4.1.4
The treatments to be evaluated are outlined in Table 4.1.4: 1 below. The number of units for 
placebo corresponds to the number of units of the respective dose level.

The trial medication will be administered to the subjects, while in a sitting position, as an oral 
dose together with approximately 240 mL of water, under supervision of the investigating 
physician or an authorised designee. The so-called four-eye principle (two-person rule) 
should be applied for administration of trial medication, if correct dosage cannot be ensured 
otherwise.
Subjects will be kept under close medical surveillance until at least 48 hours following drug 
administration. During the first 4 hours after drug administration, they are not allowed to lie 
down (i.e., no declination of the upper body of more than 45 degrees from upright posture), 
except, if required for trial-related measurements (e.g., recording of 12-lead ECG) or for
medical reasons (e.g., AEs). 
For restrictions with regard to diet, refer to Section 4.2.2.2.
Blinding and procedures for unblinding
4.1.5
Blinding
4.1.5.1
The trial is designed double-blind. The treatments administered (active or placebo) will be 
blinded to the subjects and the investigators (outcome assessors) in order to limit the 
occurrence of any bias which the knowledge of treatment may have. According to the rising 
dose design, the current dose level will be known to subjects and investigators.

At the sponsor’s site, access to the randomisation schedule is restricted to the randomisation 
operators, the Clinical Trial Support group and the Pharmaceutics Department.
The trial pharmacokineticist may receive the randomisation codes prior to official unblinding 
to perform the preliminary PK analysis. He or she will confirm in writing that the codes will 
be treated confidentially.
In addition, regarding the sponsor, all trial data will be handled open label. This means that 
trial functions of the sponsor are unblinded (trial clinical leader, data manager, statistician, 
bioanalyst, pharmacokineticist as well as dedicated CRO personnel). This is acceptable 
because they are neither in contact with subjects nor with site staff.
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.
Access to the randomisation schedule will be controlled and documented by a signed 
confidentiality statement, which will be stored in the TMF. 
Unblinding and breaking the code
4.1.5.2
The investigator or designee 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 otherwise assure safety of 
trial participants. If the envelope for a subject is opened, the sponsor must be informed 
immediately. The reason for breaking the code must be documented on the envelope and/or 
appropriate CRF page along with the date and the initials of the person who broke the code.
PK samples will be labelled in such a way that treatment allocation cannot be derived by the 
analytical site.
Packaging, labelling, and re-supply
4.1.6
The investigational medicinal products will be provided by BI. They will be packaged and 
labelled in accordance with local law and the principles of Good Manufacturing Practice. 
For details of packing and the description of the label, refer to the ISF.
No re-supply is planned.
Storage conditions
4.1.7
Drug supplies will be kept in their original packaging and in a secure limited access storage 
area 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 contacted immediately.

Drug accountability
4.1.8
The investigator/pharmacist who is documented in the trial staff list/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 institutional review board (IRB),

Availability of a signed and dated clinical trial contract between the sponsor and the 
head of the trial site,

Notification of the regulatory authority, e.g., competent authority (CA)

Availability of the curriculum vitae of the principal investigator

Availability of a signed and dated CTP
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 must be returned to sponsor. Receipt, usage and 
return must be documented on the respective forms. Account must be given for any 
discrepancies. 
The investigator/pharmacist who is documented in the trial staff list/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 return to the sponsor 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 that is documented in the trial staff list/investigational drug storage 
manager 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 return to the sponsor or appointed contract research organization
(CRO), the investigator/pharmacist who is documented in the trial staff list/investigational 
drug storage manager must verify that no remaining supplies are in the investigator’s 
possession.

OTHER TREATMENTS, EMERGENCY  PROCEDURES,
RESTRICTIONS
Other treatments and emergency procedures
4.2.1
There are no special emergency procedures to be followed. No additional treatment is 
planned. However, in case of AEs 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.

Restrictions
4.2.2
Restrictions regarding concomitant treatment
4.2.2.1
In principle, no concomitant therapy is allowed. All concomitant or rescue therapies will be 
recorded (including time of intake on study days) on the appropriate pages of the CRF.
Restrictions on diet and life style
4.2.2.2
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 hours after drug intake.
From 1 hour before drug intake until 4 hours post-dose liquid intake is restricted to the fluid 
(approximately 240 mL of water) administered with the drug and an additional approximately
240 mL of water served on Day 1 at 2 hours and 4 hours post-dose (mandatory for all 
subjects).
From 4 hours post-dose until 24 hours post-dose water intake is restricted to 3000 mL. 
During the days of urine collection, total fluid intake should be at least 1500 mL and should 
not exceed 3500 mL.
Alcoholic beverages, grapefruits, Seville oranges (sour or bitter oranges) and their juices, and 
dietary supplements and products including St. John's wort (Hypericum perforatum) are not
permitted starting 7 days before administration of trial medication until after the last PK
sample of each study period is collected.

ASSESSMENTS
5.1
ASSESSMENT OF EFFICACY
Not applicable. No efficacy endpoints will be evaluated in this trial.
5.2
ASSESSMENT OF SAFETY
Physical examination
5.2.1
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, RR, and body 
temperature), 12-lead ECG, laboratory tests, and a physical examination. At the end of study 
examination, it will include review of vital signs, 12-lead ECG, laboratory tests, and a 
physical examination.
Vital signs
5.2.2
Systolic and diastolic BP as well as PR will be measured by a BP monitor at the times 
indicated in the Flow Chart, after subjects have rested for at least 10 minutes in a supine 
position. All recordings should be made using the same type of BP recording instrument on 
the same arm if possible.
Further, RR and body temperature will be monitored. Body temperature will be determined at 
the time points indicated in the Flow Chart using electronic thermometers. RR will be 
counted by trained study personal by observing the chest movements over a period of one 
minute (30 second x 2) after the subject has rested in the supine position for 10 minutes. 
Recording of the values will be done at the time points indicated in the Flow Chart.
Safety laboratory parameters
5.2.3
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 hours. 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. 
Manual differential white blood cell count will only be performed if there is an abnormality 
in the automatic blood cell count, i.e. if automatic count is not feasible or differential WBC is 
abnormal (i.e., pathological or atypical cells) and clinically relevant in the opinion of the 
investigator.
In case the urinalysis is positive for erythrocytes, leukocytes, nitrite or protein and clinically
relevant in the opinion of the investigator, microscopic examination of the urine sediment

To achieve a stable heart rate (HR) at rest and to assure high quality recordings, the site 
personnel will be instructed to assure a relaxed and quiet environment so that all subjects are 
at complete rest. 
All ECGs will be recorded for 10-second duration after the subjects have rested for at least 
10 minutes in a supine position. ECG recordings will always precede all other study 
procedures scheduled for 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.
ECGs will be recorded as single ECGs or as triplicate ECGs (i.e., three single ECGs recorded 
within 180 second) 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 time points with triple ECGs, all three single 
ECGs will be repeated. The repeat ECGs are assigned to the respective scheduled time point. 
Additional (unscheduled) ECGs may be collected at the discretion of the investigator for 
safety reasons. These ECGs are assigned to the prior scheduled time point.
Storing
All ECGs will be stored electronically on the Muse Cardiology information System (GE 
Medical Systems, Freiburg, Germany)
Data transfer
For time points specified in the Flow Chart, ECGs will be transferred electronically to the 
central ECG lab (
) for evaluation.
All ECGs (including repeat ECGs due to quality reasons) will be sent to the central ECG lab.
The investigator will judge data adoption and send the information which ECGs were 
adopted to the central ECG lab.
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
a) Central ECG lab
A post-study centralized evaluation of all 12-lead ECGs recorded after Days 1 up to 
72 hours after drug administration will be performed by an independent ECG 
laboratory. This analysis will include the determination of cardiac axis as assessed by 
the ECG machine’s algorithm as well as the intervals RR, PR, QRS and QT measured 
semi-automatically. With the exception of the first triplicate ECG (used as baseline 
before the first drug administration), only the first of the triplicate ECG at a single 
assessment time will be evaluated. The remaining second and third replicate ECG will 
be stored for additional analyses if required, e.g., by authorities at a later time point.

HR and the QT interval corrected for HR (QTc e.g., QTcF and QTcB) will be 
determined by the sponsor (refer also to trial statistical analysis plan [TSAP] for 
details).
Abnormalities detected during centralized ECG evaluation will not necessarily qualify 
as AE. All interval measurements in one subject will be performed on the same lead. 
The intervals will be measured from four cardiac cycles (beats) in lead II. If lead II 
shows a flat T wave or is not measurable for any reason, lead V5 will be used, or if 
that lead is not measurable, then lead I will be used. The lead actually used will be 
reported in the CTR.
For blinding arrangements, 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].
b) Trial site
All local ECGs will be evaluated by the investigator or a designee.
For the inclusion or exclusion (refer to Section 3.3) of a subject and for the 
assessment of cardiac safety during the study, the QTcF 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. 
4-hours continuous 3-lead ECG monitoring
5.2.4.2
Cardiac rhythm (including heart rate) will be monitored by means of 4-hours continuous 3-
lead ECG recording using the Central Monitor DS-8700 (Fukuda, Japan) for at least 15 min 
before drug administration (for baseline assessment) and for 4 hours following drug 
administration). This 4-hours continuous 3-lead ECG monitoring supports the early detection 
of adverse events such as clinically relevant bradycardia, tachycardia, or arrhythmia at the

trial site. Beyond this clinical evaluation at the trial site, no further data collection or analyses 
are performed based on 4-hours continuous 3-lead ECG monitoring.
ECG data from 4-hours continuous 3-lead ECG recording will not be transferred to the

Assessment of adverse events
5.2.6
Definitions of adverse events
5.2.6.1
Adverse event
5.2.6.1.1
An AE is defined as any untoward medical occurrence in a subject or clinical investigation 
subject administered a medicinal product and which does not necessarily have to have a 
causal relationship with this treatment.
An AE can therefore be any unfavourable and unintended sign (including an abnormal 
laboratory finding), symptom, or disease temporally associated with the use of a medicinal 
product, whether or not considered related to the medicinal product.
The following should also be recorded as an AE in the CRF and BI SAE form (if applicable):

Worsening of pre-existing conditions

Changes in vital signs, ECG, physical examination, and laboratory test results, if they 
are judged clinically relevant by the investigator
If such abnormalities already pre-exist prior to trial inclusion, they will be considered as 
baseline conditions and should be collected in the eCRF only.
Serious adverse event
5.2.6.1.2
A 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 subject was at risk of death 
at the time of the event; it does not refer to an event that hypothetically might have 
caused death if more severe, 

Requires inpatient hospitalisation

Requires prolongation of existing hospitalisation

Results in persistent or significant disability or incapacity 

Is a congenital anomaly/birth defect 

Is deemed serious for any other reason if it is an important medical event when based 
upon appropriate medical judgment which may jeopardise the subject 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
The following events will be handled as ‘deemed serious for any other reason’. An AE which 
possibly leads to disability will be reported as an SAE.
AEs considered ‘Always Serious’
5.2.6.1.3
Cancers of new histology and exacerbations of existing cancer must be classified as a serious 
event regardless of the time since discontinuation of the trial medication and must be reported 
as described in Section 5.2.6.2, subsections ‘AE Collection’ and ‘AE reporting to sponsor 
and timelines’.
In accordance with the European Medicines Agency initiative on Important Medical Events, 
BI has set up a list of further AEs, which, by their nature, can always be considered to be 
‘serious’ even though they may not have met the criteria of an SAE as defined above.
The latest list of ‘Always Serious AEs’ can be found in the electronic data capture (eDC)
system, an electronic data capture system which allows the entry of trial data at the trial site.
Adverse events of special interest
5.2.6.1.4
The term adverse events of special interest (AESI) relates to any specific AE that has been 
identified at the project level as being of particular concern for prospective safety monitoring 
and safety assessment within this trial, e.g. the potential for AEs based on knowledge from 
other compounds in the same class. AESIs need to be reported to the sponsor’s 
Pharmacovigilance Department within the same timeframe that applies to SAEs, please refer 
to Section 5.2.6.2.2.
The following are considered as AESIs:

Hepatic injury
A hepatic injury is defined by the following alterations of hepatic laboratory 
parameters: 
o
An elevation of AST and/or ALT ≥3-fold ULN combined with an elevation of 
total bilirubin ≥2-fold ULN measured in the same blood sample, or
o
Aminotransferase (ALT and/or AST) elevations ≥10-fold ULN
These lab findings constitute a hepatic injury alert and the subjects showing these lab 
abnormalities need to be followed up according to the ‘DILI checklist’ provided in the 
ISF. In case of clinical symptoms of hepatic injury (icterus, unexplained 
encephalopathy, unexplained coagulopathy, right upper quadrant abdominal pain, 
etc.) without lab results (ALT, AST, total bilirubin) available, the Investigator should 
make sure that these parameters are analysed, if necessary in an unscheduled blood 
test. Should the results meet the criteria of hepatic injury alert, the procedures 
described in the DILI checklist should be followed.

Intensity (severity) of AEs
5.2.6.1.5
The intensity (severity) of the AE should be judged based on the following:
Mild:
Awareness of sign(s) or symptom(s) that is/are easily tolerated
Moderate:
Sufficient discomfort to cause interference with usual activity
Severe:
Incapacitating or causing inability to work or to perform usual activities
Causal relationship of AEs
5.2.6.1.6
Medical judgment should be used to determine the relationship, considering all relevant 
factors, including pattern of reaction, temporal relationship, de-challenge or re-challenge, 
confounding factors such as concomitant medication, concomitant diseases and relevant 
history.
Arguments that may suggest that there is a reasonable possibility of a causal relationship 
could be:

The event is consistent with the known pharmacology of the drug 

The event is known to be caused by or attributed to the drug class

A plausible time to onset of the event relative to the time of drug exposure

Evidence that the event is reproducible when the drug is re-introduced

No medically sound alternative aetiologies that could explain the event (e.g., pre-
existing or concomitant diseases, or co-medications)

The event is typically drug-related and infrequent in the general population not 
exposed to drugs (e.g. Stevens-Johnson syndrome)

An indication of dose-response (i.e., greater effect size if the dose is increased, 
smaller effect size if dose is reduced)
Arguments that may suggest that there is no reasonable possibility of a causal relationship 
could be:

No plausible time to onset of the event relative to the time of drug exposure is evident 
(e.g., pre-treatment cases, diagnosis of cancer or chronic disease within days/weeks of 
drug administration; an allergic reaction weeks after discontinuation of the drug 
concerned)

Continuation of the event despite the withdrawal of the medication, taking into 
account the pharmacological properties of the compound (e.g., after 5 half-lives). Of 
note, this criterion may not be applicable to events whose time course is prolonged 
despite removing the original trigger

Additional arguments amongst those stated before, like alternative explanation (e.g. 
situations where other drugs or underlying diseases appear to provide a more likely 
explanation for the observed event than the drug concerned)

Disappearance of the event even though the trial drug treatment continues or remains 
unchanged

Adverse event collection and reporting
5.2.6.2
AE collection
5.2.6.2.1
Upon enrolment into a trial, the subject’s baseline condition is assessed (for instance, by 
documentation of medical history/concomitant diagnoses), and relevant changes from 
baseline are noted subsequently. 
Subjects will be required to report spontaneously any AEs as well as the time of onset, end
time, and intensity of these events. In addition, each subject will be regularly assessed by the 
medical staff throughout the clinical trial and whenever the investigator deems necessary. As 
a minimum, subjects will be questioned for AEs (and concomitant therapies) at the time 
points indicated in the Flow Chart. Assessment will be made using non-specific questions 
such as ‘How do you feel?’. Specific questions will be asked wherever necessary in order to 
more precisely describe an AE.
A carefully written record of all AEs shall be kept by the investigator in charge of the trial. 
Records of AEs shall include data on the time of onset, end time, intensity of the event, and 
any treatment or action required for the event and its outcome.
The following must be collected and documented on the appropriate CRF(s) by the 
investigator:

From signing the informed consent onwards until an individual subject’s end of study: 
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 study:
o
The investigator does not need to actively monitor the subject for new AEs but 
should only report any occurrence of cancer and related SAEs and related 
AESIs of which the investigator may become aware of by any means of 
communication, e.g. phone call. Those AEs should, however, not be reported 
in the CRF.

AE reporting to the sponsor and timelines
5.2.6.2.2
The Investigator must report SAEs, AESIs, and non-serious AEs which are relevant for the 
reported SAE or AESI, on the BI SAE form via fax immediately (within 24 hours) 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
5.2.6.2.3
All (S)AEs, including those persisting after the individual subject’s end of trial, must be 
followed up until they have resolved, have been assessed as ‘chronic’ or ‘stable’, or no 
further information can be obtained.
Pregnancy
5.2.6.2.4
Once the male subject has been enrolled in the clinical trial and has taken trial medication, 
and if a partner of the male trial participant becomes pregnant, the investigator must report 
any drug exposure during pregnancy in a partner of the male trial participant immediately 
(within 24 hours) by means of Part A of the Pregnancy Monitoring Form to the sponsor’s 
unique entry point, after a written consent of the pregnant partner.
The outcome of the pregnancy associated with the drug exposure during pregnancy must be 
followed up and reported to the sponsor’s unique entry point on the Pregnancy Monitoring 
Form for Clinical Trials (Part B).
The ISF will contain the Pregnancy Monitoring Form for Clinical Trials (Part A and Part B) 
as well as non-trial specific information and consent for the pregnant partner.
As pregnancy itself is not to be reported as an AE, in the absence of an accompanying SAE 
and/or AESI, only the Pregnancy Monitoring Form for Clinical Trials and not the SAE form 
is to be completed. If there is an SAE and/or AESI associated with the pregnancy, an SAE 
form must be completed in addition.

visits as long as the total blood volume taken per subject does not exceed 400 mL. Such 
changes would be implemented via non-substantial CTP Amendments.
Methods of sample collection
5.3.2
Blood sampling for pharmacokinetic analysis
5.3.2.1
For quantification of BI 730357 plasma concentrations, 3 mL of blood will be taken from an 
antecubital or forearm vein into an ethylenediaminetetraacetic acid (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 minutes at about 
2000 g to 4000 g and at 4 to 8°C. Two plasma aliquots will be obtained and stored in 
polypropylene tubes. The first aliquot should contain at least 0.5 mL plasma. The process 
from blood collection until transfer of plasma aliquots into the freezer should be completed 
within 60 minutes, with interim storage of blood samples and aliquots at in ice water or on 
ice. 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.

The weight of the empty container will be determined, thereafter suitable volume of 10% 
Tween 20 will be added and the weight of the container at the end of each sampling interval 
will be determined. The urine collection container will be slightly mixed after each urine 
event. Details will be described in the lab manual.
The urine weight/volume for each collection interval will be documented (however, no 
correction for the specific gravity of urine is done, i.e., 1 L is defined to be equal to 1 kg). 
Two 0.5 mL aliquots will be stored in PP tubes for bioanalytical measurement. In case more 
than one collection container is used in an interval, the contents of all containers are to be 
mixed before aliquots are prepared. Mixing should be done by transferring the entire content 
of all collection containers into a single PE/PP or glass container, and stirring the mixed 
fractions for about 1 min (manually or using a stir bar or other stirring device out of PE, PP, 
Teflon or glass).

number, subject number, visit, and planned collection time. Further information such as 
matrix and analyte may also be provided. 
Until transfer on dry ice to the analytical laboratory, the urine samples will be stored at about 
-20°C or below at the trial site. The second aliquot will be transferred after the bioanalyst has 
acknowledged safe arrival of the first aliquot. At the analytical laboratory the urine samples 
will be stored at about -20°C or below until analysis. 
After completion of the trial the urine samples may be used for further methodological 
investigations, e.g., for stability testing, assessment of metabolites. However, only data 
related to the analyte and/or its metabolite(s) will be generated by these additional 
investigations. The study samples will be discarded after completion of the additional 
investigations but not later than 5 years upon the final study report has been signed.

INVESTIGATIONAL PLAN
6.1
VISIT SCHEDULE
Exact times of measurements outside the permitted time windows will be documented. The 
acceptable time windows for screening and end of study 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 hours-period prior to 
the trial drug administration (including blank values for PK).
The tolerance for drug administration will be ± 1 minute on Days 1.
The acceptable deviation on Day 1 from the scheduled time for vital signs and ECG will be -
15 minutes for the first 4 hours after the drug administration and - 30 minutes thereafter. 
After Day 2, vital signs and ECG will be ± 30 minutes from the scheduled time. Blood 
sampling for safety laboratory tests will be ± 30 minutes for the first 24 hours after trial drug 
administration. Urine sampling for safety laboratory tests will be -3 hours on Day 2 (24 hours
after trial drug administration).
Procedures on Days 4, 5 and 8 to be performed within ±3 hours from planned time.
If several activities 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 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.
Relevant time violations will be identified and their handling discussed no later than at the 
(blinded) report planning meeting (refer to Section 7.4).

STATISTICAL METHODS AND DETERMINATION OF
SAMPLE SIZE
7.1
STATISTICAL DESIGN – MODEL
The main objectives of this trial will be assessed by calculating descriptive statistics for 
safety as well as for PK parameters, which will be compared between the treatment groups. 
Further analyses of these endpoints comprise the power model for assessment of dose 
proportionality.
7.2
NULL AND ALTERNATIVE HYPOTHESES
It is not planned to test any statistical hypotheses in this study.
Any confidence intervals computed are 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
Analysis sets
Statistical analyses will be based on the following analysis sets:

Treated set (TS): The treated set includes all subjects who were randomized and 
treated with at least one dose of study drug. The treatment assignment will be 
determined based on the first treatment the subjects received. The treated set will be 
used for safety analyses.

Pharmacokinetic parameter analysis set (PKS): This set includes all subjects in the 
treated set (TS) who provide at least one PK endpoint that was not excluded due to a 
protocol deviation relevant to the evaluation of PK or due to PK non-evaluability (as 
specified in the following subsection ‘Pharmacokinetics’). Thus, a subject will be 
included in the PKS, even if he/she contributes only one PK parameter value for one 
period to the statistical assessment. Descriptive and model based analyses of PK 
parameters will be based on the PKS.
Adherence to the protocol will be assessed by the trial team. Important protocol 
deviations (IPD) categories will be specified in the integrated quality and risk 
management plan (IQRMP), IPDs will be identified no later than in the Report Planning 
Meeting, and the IPD categories will be updated as needed.
Pharmacokinetics
The pharmacokinetic parameters listed in Sections 2.1 and 2.2 for BI 730357 will be 
calculated according to the relevant standard operating procedure (SOP) of the Sponsor 
(001-MCS-36-472).

Plasma 
 concentration data and parameters of a subject will be included in the 
statistical pharmacokinetic (PK) analyses if they are not flagged for exclusion due to a 
protocol deviation relevant to the evaluation of PK (to be decided no later than in the 
Report Planning Meeting) or due to PK non-evaluability (as revealed during data 
analysis, based on the criteria specified below). Exclusion of a subject`s data will be 
documented in the CTR.
Relevant protocol deviations may be:

Incorrect trial medication taken, i.e. the subject received at least one dose of trial 
medication the subject was not assigned to

Incorrect dose of trial medication taken

Use of restricted medication
Plasma 
 concentrations and/or parameters of a subject will be considered as non-
evaluable, if for example 

The subject experienced emesis that occurred at or before two times median tmax
of the respective treatment (Median tmax is to be determined excluding the subjects 
experiencing emesis),

Missing samples/concentration data at important phases of PK disposition curve. 
Plasma
 concentration data and parameters of a subject which is flagged for   
exclusion will be reported with its individual values but will not be included in the 
statistical analyses.
Only concentration values within the validated concentration range and actual sampling 
times will be used for the calculation of pharmacokinetic parameters. Concentrations 
used in the pharmacokinetic calculations will be in the same format as in the 
bioanalytical report (that is to the same number of decimal places provided in the 
bioanalytical report).
Primary endpoint analyses
7.3.1
The primary endpoint as specified in Section 2.1.2 will be derived according to BI standards. 
The analysis will be based on the treated set (TS) and will be descriptive in nature.
Secondary endpoint analyses
7.3.2
Primary analyses
The secondary endpoints (refer to Section 2.1.3) will be analysed descriptively.

Safety analyses
7.3.4
Safety will be assessed as defined by the endpoints listed in Section 2.1.2 and 2.2.2 based on 
the treated set (TS). Safety analyses will be descriptive in nature and will be based on BI 
standards.
For all analyses the treatment actually administered (= treatment at onset) to the subject will 
be used (any deviations from the randomised treatment will be discussed in the minutes of the 
report planning meeting).
Treatments will be compared in a descriptive way. The placebo group in the safety evaluation 
will consist of all subjects treated with placebo, regardless of the dose group in which they 
were treated. The test treatment groups will be compared to the placebo group in a descriptive 
way. Tabulations of frequencies/proportions will be used for the evaluation of categorical 
(qualitative) data, and tabulations of descriptive statistics will be used to analyse continuous 
(quantitative) data.
Measurements (such as ECGs, vital signs, or laboratory parameters) or AEs will be assigned 
to treatments (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 intake of trial medication will be 
assigned to the screening period, those between trial medication intake and end of REP (refer 
to Section 1.2.6) will be assigned to the treatment period. Events occurring after the REP but 
prior to trial termination date will be assigned to ‘follow-up’. These assignments including 
the corresponding time intervals will be defined in detail in the TSAP.  Note that AEs 
occurring after the last per protocol contact but entered before database lock will be reported 
to Pharmacovigilance only and will not be captured in the trial database.
Additionally, further treatment intervals (called analysing treatments) may be defined in the 
TSAP in order to provide summary statistics for other than above periods , such as combined 
treatments, on-treatment totals, or periods without treatment effects (such as screening and 
post-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 5.2.6.1) and other significant 
AEs (according to ICH E3) will be listed separately. 
Previous and concomitant therapies will be presented per treatment group without 
consideration of time intervals and treatment periods.

Laboratory data will be compared to their reference ranges. Values outside the reference 
range as well as possibly clinically significant values will be highlighted in the listings. 
Additionally, differences from baseline will be evaluated.
Vital signs or other safety-relevant data will be assessed with regard to possible on-treatment 
changes from baseline.
The ECG variables QT, HR, QTcF, QTcB, PR, QRS, and RR obtained from the centralised 
evaluation of 12-lead ECG recordings will be the basis for the derivation of quantitative and 
categorical ECG endpoints. These endpoints and their analyses will be described in the 
TSAP.

INTERIM ANALYSES
No interim analysis is planned.
7.5
HANDLING OF MISSING DATA
Safety
7.5.1
It is not planned to impute missing values for safety parameters.
Plasma/urine drug concentration - time profiles
7.5.2
Handling of missing PK data will be performed according to the relevant SOP of the Sponsor 
(001-MCS-36-472_RD-01).
Drug concentration data identified with no sample available (NOS), no valid result (NOS), 
not analysed (NOA), BLQ, or no peak detectable (NOP) 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).
Pharmacokinetics
7.5.3
Handling of missing PK data will be performed according to the relevant SOP of the Sponsor 
(001-MCS-36-472_RD-01).
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.
7.6
RANDOMISATION
Subjects will be randomised within each dose group in a 3:1 ratio (test treatment to placebo).
The sponsor will arrange for the randomisation as well as packaging and labelling of trial 
medication. The randomisation list will be generated using a validated system that uses a

pseudo-random number generator and a supplied seed number so that the resulting allocation 
is both reproducible and non-predictable. 
The randomisation list will contain additional blocks to allow for subject replacement (refer 
to Section 3.3.5).
7.7
DETERMINATION OF SAMPLE SIZE
It is planned to include a total of 24 subjects in this trial. The planned sample size is not based 
on a power calculation. The size of 8 subjects per dose group (6 on active treatment, and 2 on 
placebo) is commonly used in SRD studies of the present type and is in general considered as 
sufficient for the exploratory evaluation of single dose safety and pharmacokinetics.

Declaration of Helsinki, in accordance with the International Council for Harmonisation of 
Technical Requirements for Pharmaceuticals for Human Use (ICH) Harmonised Guideline 
for GCP and relevant BI SOPs, the Japanese GCP regulations (Ministry of Health and 
Welfare Ordinance No. 28, March 27, 1997), and other relevant regulations. Investigators and 
site staff must adhere to these principles.
Standard medical care (prophylactic, diagnostic and therapeutic procedures) remains the 
responsibility of the treating physician of the subject.
The investigator will inform the sponsor immediately of any urgent safety measures taken to 
protect the trial subjects against any immediate hazard, and also of any serious breaches of 
the protocol or of ICH-GCP and Japanese GCP.
The BI transparency and publication policy can be found on the following web page: 
trials.boehringer-ingelheim.com. The rights of the investigator and of the sponsor with regard 
to publication of the results of this trial are described in the investigator contract. As a rule, 
no trial results should be published prior to finalization of the CTR.
The certificate of insurance cover is made available to the investigator and the subjects, and is 
stored in the ISF.
8.1
TRIAL APPROVAL, SUBJECT INFORMATION, INFORMED CONSENT
This trial will be initiated only after all required legal documentation has been reviewed and 
approved by the respective IRB/independent ethics committee (IEC) and 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 retained by the investigator as part of the trial records. A signed copy of the 
informed consent and any additional subject information must be given to each subject or the 
subject’s legally accepted representative.
The investigator or delegate must give a full explanation to trial subjects based on the subject
information form. A language understandable to the subject should be chosen, technical terms 
and expressions avoided, if possible. 
The subject must be given sufficient time to consider participation in the trial. The 
investigator or delegate obtains written consent of the subject’s own free will with the 
informed consent form after confirming that the subject understands the contents. The 
investigator or his delegate must sign (or place a seal on) and date the informed consent form.

If a trial collaborator has given a supplementary explanation, the trial collaborator also signs 
(or places a seal on) and dates the informed consent.
Re-consenting may become necessary when new relevant information becomes available and 
should be conducted according to the sponsor’s instructions.
The consent and re-consenting process should be properly documented in the source 
documentation.
8.2
DATA QUALITY ASSURANCE
A risk-based approach is used for trial quality management. It is initiated by the assessment
of critical data and processes for trial subject protection and reliability of the results as well as 
identification and assessment of associated risks. An Integrated Quality and Risk 
Management Plan documents the rationale and strategies for risk management during trial 
conduct including monitoring approaches, vendor management and other processes focusing 
on areas of greatest risk. 
Continuous risk review and assessment may lead to adjustments in trial conduct, trial design 
or monitoring approaches. 
A quality assurance audit/inspection of this trial may be conducted by the sponsor, sponsor’s 
designees, or by IRB/IEC, or by regulatory authorities. The quality assurance auditor will 
have access to all medical records, the investigator’s trial-related files and correspondence, 
and the informed consent documentation of this clinical trial
8.3
RECORDS
CRFs for individual subjects will be provided by the sponsor. Refer to Section 4.1.5.2 for 
rules about emergency code breaks. For drug accountability, refer to Section 4.1.8.
Source documents
8.3.1
In accordance with regulatory requirements, the investigator should prepare and maintain 
adequate and accurate source documents and trial records that include all observations and 
other data pertinent to the investigation on each trial subject. Source data as well as reported 
data should follow the “ALCOA principles” and be attributable, legible, contemporaneous, 
original and accurate. Changes to the data should be traceable (audit trail).
Data reported on the CRF must be consistent with the source data or the discrepancies must 
be explained.
The current medical history of the subject may not be sufficient to confirm eligibility for the 
trial and the investigator may need to request previous medical histories and evidence of any 
diagnostic tests. In this case, the investigator must make three documented attempts to 
retrieve previous medical records. If this fails, a verbal history from the subject, documented 
in their medical records, would be acceptable.
Before sending or uploading those copies, the investigator must ensure that all subject 
identifiers (e.g., subject’s name, initials, address, phone number, social security number) have 
properly been removed or redacted from any copy of the subjects’ source documents.

If the subject is not compliant with the protocol, any corrective action e.g., re-training must 
be documented in the subject file.
For the CRF, data must be derived from source documents, for example:

Subject identification: gender, year of birth (in accordance with local laws and 
regulations)

Subject participation in the trial (substance, trial number, subject number, date subject 
was informed)

Dates of subject’s visits, including dispensing of trial medication

Medical history (including concomitant diseases, if applicable)

Medication history

AEs and outcome events (onset date (mandatory), and end date (if available))

SAEs (onset date (mandatory), and end date (if available))

Concomitant therapy (start date, changes)

Originals or copies of laboratory results and other imaging or testing results, with proper 
documented medical evaluation (in validated electronic format, if available)

Completion of subject’s participation in the trial” (end date; in case of premature 
discontinuation document the reason for it).
Prior to allocation of a subject to a treatment into a clinical trial, there must be documented 
evidence in the source data (e.g., medical records) that the trial participant meets all inclusion 
criteria and does not meet any exclusion criteria. The absence of records (either medical 
records, verbal documented feedback of the subject or testing conducted specific for a 
protocol) to support inclusion/exclusion criteria does not make the subject eligible for the 
clinical trial.
Direct access to source data and documents
8.3.2
The investigator/institution will allow site trial-related monitoring, audits, IRB/IEC review 
and regulatory inspections. Direct access must be provided to the CRF and all source 
documents/data, including progress notes, copies of laboratory and medical test results, which 
must be available at all times for review by the clinical research associate (CRA), auditor and 
regulatory inspector (e.g., FDA). They may review all CRFs and informed consents. The 
accuracy of the data will be verified by direct comparison with the source documents 
described in Section 8.3.1.
The sponsor will also monitor compliance with the protocol and GCP.
Storage period of records
8.3.3
Trial site:
The trial site must retain the source and essential documents (including ISF) according to 
contract or the local requirements valid at the time of the end of the trial (whatever is longer).
Sponsor:
The sponsor must retain the essential documents according to the sponsor’s SOPs.
