RATIONALE, OBJECTIVES, AND BENEFIT - RISK 
ASSESSMENT
2.1
RATIONALE FOR PERFORMING THE TRIAL
As a transition from preclinical investigations to clinical development in this first-in-man 
trial, safety, tolerability, pharmacokinetics, and pharmacodynamics of BI 1323495 will be 
assessed in healthy male volunteers using single rising oral doses in order to provide the basis 
for a potential ongoing clinical development of BI 1323495 
 
Healthy male subjects aged 18 - 45 years will be recruited for this study. They provide a 
relatively stable physiological, biochemical, and hormonal basis (steady state) for studying 
drug effects, they show no disease-related variation, and they are not taking concomitant 
medication. 
Within each dose group, all actively treated individuals will receive the same BI 1323495
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.
It is intended to investigate the following dose levels of BI 1323495 in this trial: 
 mg.
The background for this dose selection is described in the following paragraphs.
2.1.1
Starting dose
It is best practice to use different methods for dose selection and to take a starting dose at the
lower end of the dose range if different methods give different estimates (err on the side of
caution).
Applying the respective calculation as given in the US FDA Guidance for Industry 
'Estimating the Maximum Safe Starting Dose in Initial Clinical Trials for Therapeutics in 
Adult Healthy Volunteers' (R06-1037), and assuming a no adverse effect level (NOAEL) of 
 a maximum recommended starting dose (MRSD) as high as 
could be 
selected based on the 4 week toxicology data 
 A detailed description of the derivation 
of the MRSD can be found in the IB (c21238478-01).
The therapeutic human dose of BI 1323495 is predicted to be 
(see Section 
1.2.4). The starting dose should be sub-therapeutic; therefore it should be lower than the 
expected therapeutic dose. Application of a factor of 10 to the predicted therapeutic human 
dose results in a maximum recommended safe starting dose of approximately 
 in 
humans. 
A single dose of 
is predicted to achieve exposures of 
 
which is well below expected therapeutic exposures of 
 
providing even sufficient margin to therapeutic exposures should the 
bioavailability be higher than the predicted 
 (see Section 1.2.4).

Finally, another commonly used NOAEL-based approach, following ICH guidance M3 (R2), 
is to use a fraction of the NOAEL, e.g. 1/50 or 1/100 (R09-1400). Based on the 
NOAEL 
of 
 body weight and assuming a body weight of 50 kg the starting dose would be in 
the range of 
Taken together, different approaches give a starting dose in the range of


Published experience from clinical trials with administration of 
 
and achieving higher levels of target engagement over longer periods of time not 
revealing any mode of action-related adverse effects (Section 1.2.5);

the toxicological profile of BI 1323495 in relevant animal models (Section 1.2.2);

the effect 
 being reversible;

only single doses being applied;

lower peak exposures being expected in 
Therefore at expected exposures achieved with this dose,

trigger any relevant or unacceptable biological activity (Section 1.2.5).
2.1.2
Maximum dose and dose escalation
As stated above, a minimum daily dose of about 
 may be required to achieve 
therapeutic systemic exposure of BI 1323495. Nevertheless, it is planned to explore higher 
doses / exposures in this trial for several reasons. Subsequent clinical trials in patients might 
show that required therapeutic doses and exposures are significantly higher than predicted. 
Also, higher doses / exposures might be required for more severe disease states, for induction 
vs. maintenance treatment, and for other indications. So while higher doses and exposures
might still be well tolerated they provide a larger magnitude of therapeutic effects. Further, 
testing of doses higher than 
 is also reasonable to compensate for any bioavailability 
and half-life being lower/shorter than expected. If, for example, bioavailability was 
significantly less than the predicted 
 (see Section 1.2.4), the therapeutic dose could 
eventually turn out to be several fold higher than currently predicted. And even if the 
therapeutic dose turns out to be as low as 
 higher than therapeutic doses / exposures 
are typically explored in the well-controlled clinical environment of first-in-man trials to 
provide a safety margin for following trials, e.g. drug-drug-interaction trials, trials with 
patients with impaired excretion function, etc., where substantial increases in exposure may 
be seen.
The maximum human exposure to BI 1323495 in this trial will be limited to 
 nM for 
Cmax and 
 nM*h for AUC0-24.
This provides a safety margin with a factor of at least 24 (Cmax) and 21 (AUC) to the 
exposures achieved after 4-week administration of 
/kg in the most sensitive species,

These findings are not expected after a single administration of BI 1323495 at doses 
achieving exposure levels well below exposures 
 
With respect to the NOAEL 
 in the 4-week toxicity study 
 
 the maximum human exposure defined above 
provides safety factors of 16 and 10, respectively. The given safety margins refer to the lower 
exposures 
With respect to the NOAEL in 
 in the 4-week toxicity study  
 this maximum 
human exposure provides safety margins of approximately 28 and 34, respectively.
On the other hand, the defined acceptable maximum exposure for this trial provides a margin 
of factor 
 (Cmax) and  (AUC) above the expected therapeutic exposure 
 
 to explore the therapeutic potential of the compound. 
For the present trial, a maximum dose of 
has been selected, but this dose will only be 
administered if, based on interim PK measurements (see Section 7.3.4), individual Cmax or 
AUC0-24 values at a lower dose or predicted geometric mean values of Cmax or mean AUC0-24
do not exceed exposure limits defined above. Otherwise dose escalation will be stopped at 
lower doses. Based on the preclinical safety profile of BI 1323495, these exposure limits are 
anticipated to be safe and well tolerated.
The escalation schedule has been chosen in a way that a shallow escalation will be applied for 
the higher dose levels with a factor not greater than 1.5. This dose escalation is considered to 
be adequate and safe, particularly when the selected exposure safety margins are taken into 
consideration.

Conclusion
The safe starting dose in this study is determined to be 
 This dose is not expected to 
trigger any relevant or unacceptable biological activities.

The following dose escalation scheme is planned: 
as single oral dose. Dose escalation will be guided by interim PK measurements (see Section 
7.3.4) and projected exposure levels.

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 in patients with 
The subjects are exposed to the risks of the study procedures and the risks 
related to the exposure to the trial medication.
2.3.1
Procedure-related risks
The use of an indwelling venous catheter for the purpose of blood sampling may be 
accompanied by mild bruising and also, in rare cases, by transient inflammation of the wall of 
the vein. In addition, in rare cases a nerve might be injured while inserting the venous 
catheter, potentially resulting in paresthesia, reduced sensibility, and/or pain for an indefinite 
period. The same risks apply to venipuncture for blood sampling.
The total volume of blood withdrawn during the entire study per subject will not exceed the 
volume of a normal blood donation (500 mL). No health-related risk to healthy subjects is 
expected from this blood withdrawal.
2.3.2
Drug-related risks
Factors of risk may derive from particular knowledge or the lack thereof, regarding (1) the 
mode of action, (2) the nature of the target, (3) the relevance of animal models and/or (4) 
findings in non-clinical safety studies.

Drug-induced liver injury
Although rare, a potential for drug-induced liver injury (DILI) is under constant surveillance 
by sponsors and regulators. Therefore, this trial requires timely detection, evaluation, and 
follow-up of laboratory alterations in selected liver laboratory parameters to ensure subjects´ 
safety, see also Section 5.2.2.1, adverse events of special interest.
2.3.3
Safety measures

Dose selection was based on a sound preclinical package including 4 week toxicological 
studies (see Section 1.2.3) and non-clinical pharmacology data (Section 1.2.1).
Careful selection of starting dose as described in Section 2.1. 
Dose escalation will be shallow with an increase of not more than 1.5 fold at the higher 
dose groups.


Measurement of BI 1323495 plasma concentrations and preliminary determination of PK 
parameters (Cmax, AUC0-24, see Section 7.3.4). For precautionary reasons, drug plasma 
concentrations in this healthy volunteer trial should not exceed a Cmax of 
 or an
AUC0-24 of 
and will be considered as a preliminary threshold (see Section 
2.1). Further dose progression would only be allowed after a safety interim analysis and 
filing and approval of a substantial CTP amendment.

For safety reasons, each dose group of 8 subjects (6 on active, 2 on placebo) will be 
divided into three cohorts. In the 1st cohort only 2 subjects will be treated: one subject
will receive active treatment, the other subject will receive placebo. If BI 1323495
treatment is safe and well tolerated in this first cohort, the following 2 subjects on active 
will be treated in the 2nd cohort with drug administration occurring not earlier than 24
hours after the first subject of the dose level received active treatment. The remaining 4 
subjects (either active or placebo) are the third cohort and will be treated no sooner than 
48 hours following the 1st cohort. Within each cohort, a time interval of at least 10 min 
will be maintained between administrations of study drug.
This design ensures that between first and second active dose of each dose level there is a 
time interval of at least 24 hours, which is expected to be sufficient to detect relevant first 
acute effects of BI 1323495.

Only if the respective dose of BI 1323495 was safe and showed acceptable tolerability 
and if no stopping criterion was met (see 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).
A documented Safety Review must take place prior to each dose escalation (see Section 
3.1).

An extensive safety laboratory will be performed (see Section 5.2.3).

A thorough ECG monitoring including continuous ECG measurement over 4 hours post-
dose and repeated 12-lead ECGs during the observation period 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 34
hours after study drug administration. Based on an anticipated half-life of BI 1323495 of 
approximately 
 this is expected to cover the period of highest risk / peak effect.

During in-house confinement the subjects will be under medical observation and 
thoroughly monitored for both expected and unexpected adverse events.
In summary, although not tested in humans to date, BI 1323495 has the potential to become 
an oral treatment for patients with 
. Based upon preclinical data for BI 1323495 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 first-in-man clinical trial with BI 1323495. Considering the medical need 
of the development of an effective treatment for patients with

DESCRIPTION OF DESIGN AND TRIAL POPULATION
3.1
OVERALL TRIAL DESIGN AND PLAN
This single-rising dose trial is designed as single-blind, partially randomised, and placebo-
controlled within parallel dose groups.
A total of 64 healthy male subjects is planned to participate in the trial, according to 8 
sequential groups comprising 8 subjects per group. However, additional subjects may be 
entered to allow testing of additional doses on the basis of experience gained during the trial 
conduct (e.g., preliminary PK data), provided the planned and approved highest dose will not 
be exceeded. Thus, the actual number of subjects entered may exceed 64, but will not exceed 
80 subjects entered. Such changes may be implemented via non-substantial CTP 
Amendments provided additional doses are used for the further evaluation of 
pharmacokinetics or pharmacodynamics in the absence of new safety signals. The addition of 
dose groups to further evaluate safety findings may be implemented only after notification of 
a substantial amendment.
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. Each dose group will consist of 3 cohorts 
which will be treated subsequently for safety reasons.
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 6 days 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. Furthermore, an 
unscheduled safety review meeting can be requested any time for any reasonable cause by the 
Principal Investigator (or an authorised deputy) or the sponsor of the study, e.g. because of 
any unforeseen adverse events, etc. Dose escalation will only be permitted if no safety

concerns exist in the opinion of the Principal Investigator (or an authorised deputy) and the 
trial clinical monitor (or an authorised deputy).
Although no formal Safety Review meeting will take place within a given dose group, safety 
will be continuously monitored during this trial, and an individual will only be dosed in the 
absence of any safety concern (i.e., no dose-limiting events occurred) and if none of the pre-
specified trial-specific stopping criteria have been met (refer to Section 3.3.4.2).
The minimum data set for review consists of the following data:

AEs in the current* and preceding dose groups including clinically relevant findings 
from ancillary safety testing listed below up to at least 48 h post-dosing.
Note: AEs may be ongoing at the time of Safety Reviews and AE information may be 
subject to change prior to Database Lock.
 

Vital signs in the current* and preceding dose groups up to at least 48 h post-dosing

Clinical laboratory tests in the current* and preceding dose groups up to at least 24 
hours post-dose

Preliminary PK data for selected time points as per Section 7.3.4

Check of criteria for stopping subject treatment as per Section 3.3.4.1
*”Current dose group” means: all subjects of that dose group with at least 4 subjects being on active treatment.
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 low and/or
intermediate dose levels) on the basis of experience gained during the study, provided the 
planned and approved highest dose is not exceeded. In this case, the total number of subjects 
in this trial might increase. The investigator and/or the sponsor should stop dose escalation in 
case the safety evaluation leads to concerns that would not allow higher dosing.
An overview of all relevant trial activities is provided in the Flow Chart. For visit schedules 
and details of trial procedures at selected visits, refer to Sections 6.1 and 6.2, respectively.

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 1323495.
With the rising dose design, single-blind conditions regarding the subject’s treatment (active 
or placebo) are maintained within each dose group. However, the current dose level will be 
known to subjects and investigators. The disadvantage of this trial design is a possible 
observer bias with regard to the dose-depending effects as well as time effects, but it has the 
virtue of minimizing subject risk by sequentially studying ascending doses. As time-effects 
are expected to be small relative to the differences between the doses in the broad range 
investigated, unbiased comparisons between treatments can still be expected.

It is standard in trials involving healthy volunteers to include a placebo group as control for 
the evaluation of safety 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. 
3.3
SELECTION OF TRIAL POPULATION
It is planned that 64 healthy male subjects will enter the study. The actual number of subjects 
entered may exceed the total of 64 if additional intermediate doses will be tested (see Section 
3.1). Subjects will be recruited from the volunteers' pool of the trial site.
Only male subjects will be included into the study because hitherto no data on reproductive 
toxicology are available.
A log of all subjects enrolled into the trial (i.e. having given informed consent) will be 
maintained in the ISF at the investigational site irrespective of whether they have been treated 
with investigational drug or not.

examination
For study restrictions, refer to Section 4.2.2.
3.3.4
Removal of subjects from therapy or assessments
3.3.4.1
Removal of individual subjects
An individual subject is to be removed from the trial if:
1. The subject withdraws consent for trial treatment or trial participation, without the need to 
justify the decision
2. The subject needs to take concomitant drugs that interfere with the investigational  
product or other trial medication
3. The subject is no longer able to participate for other medical reasons (such as surgery, 
adverse events (AEs), or diseases)
4. The subject shows an elevation of AST and/or ALT ≥3-fold ULN combined with an 
elevation of total bilirubin ≥2-fold ULN (measured in the same blood sample) and/or 
needs to be followed up according to the ‘DILI checklist’ provided in the ISF.
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. Dose escalation will be terminated if more than 50% of the 
subjects at one dose level show drug-related and clinically relevant adverse events of 
moderate or severe intensity.

No further subjects will be dosed without thorough re-evaluation of the benefit-risk ratio, 
if severe non-serious adverse events considered as drug-related by the investigator are 
reported in 2 subjects of the same dose group or if at least one drug-related serious 
adverse event is reported.
2. The expected enrolment goals overall 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. absolute QT or QTc greater than 
500 which has been confirmed by a repeat ECG recording or QTc increase of greater 60
ms from baseline in connection with absolute QT or QTc greater than 500 ms, which has 
been confirmed by a repeat ECG recording.
6. Dose escalation will be stopped if the Cmax or AUC0-24 of at least 1 subject of one dose 
group increases above the following exposure thresholds or if the estimated systemic 
exposure (group gMean values) of the next dose level is expected to exceed a Cmax of 
nM or an AUC0-24 of 
 nM*h. In this case, one or two dose levels lower than 
the planned next dose level may be given, as long as the expected systemic exposure 
(group gMean values) of each dose is not expected to exceed the aforementioned
thresholds.
3.3.5
Replacement of subjects
In case some subjects do not complete the trial or there is not a sufficient number of subjects 
on active within one dose group (see Section 3.1), the trial clinical monitor together with the 
trial pharmacokineticist and the trial statistician are to decide if and how many subjects will 
be replaced. A replacement subject will be assigned a unique study subject number, and will 
be assigned to the same treatment as the subject he replaces.

4.1.2
Method of assigning subjects to treatment groups
Prior to the screening visit, subjects will be contacted in writing and informed about the 
planned visit dates. The subjects willing to participate will be recruited to dose cohorts 
according to their temporal availability. As soon as enough subjects have been allocated to a 
dose cohort, 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 will be provided 
to the trial site in advance. The allocation of subjects to study subject numbers will be 
performed prior to the first administration of trial medication. For this purpose, the subjects 
will be allocated to a study subject number by drawing lots. Once a subject number has been 
assigned, it cannot be reassigned to any other subject.
The randomisation procedure is described in Section 7.5.

position, as an oral dose together with about 240 mL of water under supervision of the 
investigating physician or an authorised designee. The so-called four-eye principle (two-
person rule) should be applied for administration of trial medication and – if applicable – its 
preparation (e.g. reconstitution), if correct dosage cannot be ensured otherwise.

Administration will be performed following an overnight fast, which is to start no later than 
10 h before the scheduled dosing. 
Subjects will be kept under close medical surveillance until 24 h following drug 
administration. During the first 4 h 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 for 
medical examination), or to sleep. For restrictions with regard to diet see Section 4.2.2.2.
4.1.5
Blinding and procedures for unblinding
4.1.5.1
Blinding
The treatments administered (active or placebo) will be single-blind (that is, subjects will not 
know whether they receive active treatment or placebo). However, the current dose level will 
be known to the subjects. 
PK samples will be labelled in such a way that treatment allocation cannot be derived by the 
analytical site. The trial bioanalyst and pharmacokineticist may receive the randomisation 
codes prior to official unblinding to perform the interim / preliminary PK analysis. He or she 
will treat the codes confidentially.
In addition, the drug metabolism scientist may receive the randomization 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 central ECG lab, the staff involved with interval measurements will be blinded 
with respect to the treatment and also with regard to the recording date and time as well as 
planned time points of the ECGs. The interval measurements for a given subject will be 
performed in a random and blinded sequence by a single technician.
If an interim safety analysis of ECG data is required, a part of the staff of the central ECG lab 
may be unblinded. This part of the staff will be strictly separated from the blinded staff 
members who are involved with ECG interval measurements and assessments of ECGs.
The database of this trial will be handled open-label, because no bias with regard to data 
cleaning or safety measures is expected. This is considered acceptable because the potential 
for bias seems to be low and does not outweigh practical considerations.
4.1.5.2
Procedures for emergency unblinding
As this trial will be conducted single-blinded, the treatment information will be known to the 
investigator. Therefore, no emergency envelopes will be provided.
4.1.6
Packaging, labelling, and re-supply
Drug supplies will be provided by the Department of Pharmaceutical Development of 
Boehringer Ingelheim Pharma GmbH & Co. KG, Biberach, Germany.
The clinical trial supply consists of containers holding the trial medication, which are labelled
with trial identification. The required information according to the German Drug Law as well

No re-supply is planned.
4.1.7
Storage conditions
Drug supplies will be kept in their original packaging and in a secure limited access storage 
area according to the recommended (labelled) storage conditions. Where necessary, a 
temperature log must be maintained to make certain that the drug supplies are stored at the 
correct temperature. If the storage conditions are found to be outside the specified range, the 
local clinical monitor (as provided in the list of contacts) is to be immediately contacted.
4.1.8
Drug accountability
The investigator will receive the investigational drugs delivered by the sponsor when the 
following requirements are fulfilled:

Approval of the trial protocol by the IRB / ethics committee

Approval/notification of the regulatory authority, e.g. competent authority

Availability of the curriculum vitae of the principal investigator

Availability of a signed and dated clinical trial protocol  
Only authorised personnel as documented in the form ‘Trial Staff List’ may dispense 
medication to trial subjects. The trial medication must be administered in the manner 
specified in the CTP. All unused medication will be disposed locally by the trial site upon 
written authorisation by the clinical monitor. Receipt, usage and disposal must be 
documented on the respective forms. Account must be given for any discrepancies. 
The investigator must maintain records of the product’s delivery to the trial site, the inventory 
at the site, the use by each subject, and the disposal of unused products.

These records will include dates, quantities, batch / serial numbers, expiry (‘use-by’) dates, 
and the unique code numbers assigned to the investigational products and trial subjects. The 
investigator will maintain records that document adequately that the subjects were provided 
the doses specified by the CTP, and that reconcile all investigational products received from 
the sponsor. At the time of disposal, the investigator must verify that no remaining supplies 
are in the investigator’s possession.

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.
The following should also be recorded as an AE in the CRF and BI SAE form (if applicable): 

Worsening of the underlying disease or of other pre-existing conditions  

Changes in vital signs, ECG, physical examination, and laboratory test results, if they 
are judged clinically relevant by the investigator. 
If such abnormalities already exist prior to trial inclusion, they will be considered as baseline 
conditions and should be collected in the CRF only.

Serious adverse event
A serious adverse event (SAE) is defined as any AE which fulfils at least one of the 
following criteria:

results in death, 

is life-threatening, which refers to an event in which the patient was at risk of death 
at the time of the event; it does not refer to an event that hypothetically might have 
caused death if more severe,

requires inpatient hospitalisation,

requires prolongation of existing hospitalisation,

results in persistent or significant disability or incapacity, 

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 patient and may 
require medical or surgical intervention to prevent one of the other outcomes listed in 
the above definitions. Examples of such events are intensive treatment in an 
emergency room or at home for allergic bronchospasm, blood dyscrasias, or 
convulsions that do not result in hospitalisation or development of dependency or 
abuse. 
AEs considered ‘Always Serious’
Cancers of new histology and exacerbations of existing cancer must be classified as a serious 
event regardless of the time since discontinuation of the drug and must be reported as 
described in 5.2.2.2, subsections ‘AE Collection’ and ‘AE reporting to sponsor and 
timelines’.
In accordance with the European Medicines Agency initiative on Important Medical Events, 
Boehringer Ingelheim has set up a list of further AEs, which by their nature, can always be 
considered to be ‘serious’ even though they may not have met the criteria of an SAE as 
defined above.
The latest list of ‘Always Serious AEs’ can be found in the eDC system, an electronic data 
capture system which allows the entry of trial data at the trial site. These events should 
always be reported as SAEs as described above.
Adverse events of special interest (AESIs)
The term AESI relates to any specific AE that has been identified at the project level as being 
of particular concern for prospective safety monitoring and safety assessment within this trial, 
e.g. the potential for AEs based on knowledge from other compounds in the same class. 
AESIs need to be reported to the sponsor’s Pharmacovigilance Department within the same 
timeframe that applies to SAEs, please see Section 5.2.2.2.
The following are considered as AESIs:

Hepatic injury
A hepatic injury is defined by the following alterations of hepatic laboratory 
parameters:

o
an elevation of AST (aspartate aminotransferase) and/or ALT (alanine 
aminotransferase) ≥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
The intensity (severity) of the AE should be judged based on the following:
Mild:
Awareness of sign(s) or symptom(s) that is/are easily tolerated
Moderate:
Sufficient discomfort to cause interference with usual activity
Severe:
Incapacitating or causing inability to work or to perform usual activities
Causal relationship of AEs
Medical judgment should be used to determine the relationship, considering all relevant 
factors, including pattern of reaction, temporal relationship, de-challenge or re-challenge, 
confounding factors such as concomitant medication, concomitant diseases and relevant 
history.
Arguments that may suggest that there is a reasonable possibility of a causal relationship 
could be:

The event is consistent with the known pharmacology of the drug.

The event is known to be caused by or attributed to the drug class.

A plausible time to onset of the event relative to the time of drug exposure.

Evidence that the event is reproducible when the drug is re-introduced.

No medically sound alternative aetiologies that could explain the event (e.g. pre-
existing or concomitant diseases, or co-medications).

The event is typically drug-related and infrequent in the general population not 
exposed to drugs (e.g. Stevens-Johnson syndrome).

An indication of dose-response (i.e. greater effect size if the dose is increased, smaller 
effect size if dose is 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. 
5.2.2.2
Adverse event collection and reporting
AE collection
Upon enrolment into a trial, the subject’s baseline condition is assessed (for instance, by 
documentation of medical history/concomitant diagnoses), and relevant changes from 
baseline are noted subsequently. 
Subjects will be required to report spontaneously any AEs as well as the time of onset, end, 
and intensity of these events. In addition, each subject will be regularly assessed by the 
medical staff throughout the clinical trial and whenever the investigator deems necessary. As 
a minimum, subjects will be questioned for AEs (and concomitant therapies) at the time 
points indicated in the Flow Chart. Assessment will be made using non-specific questions 
such as ‘How do you feel?’. Specific questions will be asked wherever necessary in order to 
more precisely describe an AE.
A carefully written record of all AEs shall be kept by the investigator in charge of the trial. 
Records of AEs shall include data on the time of onset, end time, intensity of the event, and
any treatment or action required for the event and its outcome.
The following must be collected and documented on the appropriate CRF(s) by the 
investigator:

From signing the informed consent onwards until an individual subject’s end of trial: 
o
All AEs (serious and non-serious) and all AESIs
o
The only exception to this rule are AEs (serious and non-serious) and AESIs 
in Phase I trials in healthy volunteers, when subjects discontinue from the trial 
due to screening failures prior to administration of any trial medication. In

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 by any means of 
communication, e.g. phone call. Those AEs should, however, not be reported 
in the CRF.

AE reporting to sponsor and timelines
The Investigator must report SAEs, AESIs, and non-serious AEs that are relevant for the 
reported SAE or AESI, on the BI SAE form via fax 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 relevant to these events, a follow-up SAE form has to 
be provided.. For follow-up information, the same rules and timelines apply as for the initial 
information.
Information required
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
Once a 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 a male trial participant immediately (within 
24 hours) by means of Part A of the Pregnancy Monitoring Form to the sponsor’s unique 
entry point. This requires 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.
5.2.3
Assessment of safety laboratory parameters
For the assessment of laboratory parameters, blood 
 samples will be collected by the 
trial site at the time points indicated in the Flow Chart after the subjects have fasted for at 
least 10 h. Overnight fasting is not required at the discretion of the investigator or designee
for retests.
 
The parameters that will be determined are listed in Tables 5.2.3: 1 and 5.2.3: 2. Reference 
ranges will be provided in the ISF.

5.2.4.1
12-lead resting ECG
Recording
Twelve-lead resting ECGs (I, II, III, aVR, aVL, aVF, V1 - V6) will be recorded using a 
computerised electrocardiograph (CardioSoft EKG System, GE Medical Systems, Freiburg, 
Germany) at the time points given in the Flow Chart. Electrode placement will be performed 
according to the method of Wilson, Goldberger and Einthoven modified by Mason and Likar 
(hips and shoulders instead of ankles and wrists). Precise electrode placement will be marked 
with an indelible mark on the skin to allow reproducible placement throughout the inhouse 
confinement.
To achieve a stable heart rate at rest and to assure high quality recordings, the site personnel 
will be instructed to assure a relaxed and quiet environment so that all subjects are at 
complete rest.
All ECGs will be recorded for 10 sec duration after subjects have rested for at least 5 min in a 
supine position. ECG recording should precede all other study procedures scheduled for the 
same time to avoid compromising ECG quality.
ECGs will be recorded as single ECGs or as triplicate ECGs (i.e. three single ECGs recorded 
within 180 sec) as indicated in the Flow Chart.
ECGs may be repeated for quality reasons for instance due to alternating current artefacts, 
muscle movements, or electrode dislocation. For repetition within triplicate ECGs the time 
window of 180 sec applies as well. The repeat ECGs are assigned to the respective scheduled 
time point.
Additional (unscheduled) ECGs may be recorded for safety reasons. These ECGs are 
assigned to the prior scheduled time point in the sponsor’s database.
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 ECG recordings including repeat ECGs will be sent to the central ECG lab which will 
select the ECGs with the best quality at each time point.

Abnormal findings, irrespective of whether they originate from central or local evaluation, 
will be reported as AEs (during the trial) or baseline conditions (at screening) if judged 
clinically relevant by the investigator.
Any ECG abnormalities will be monitored carefully and, if necessary, the subject will be 
removed from the trial and will receive the appropriate medical treatment. 
5.2.4.2
Continuous ECG monitoring
Cardiac rhythm (including heart rate) will be monitored by means of continuous 3-lead ECG 
recording using the CARESCAPE Monitor B450 (GE Healthcare, Freiburg, Germany) for at 
least 15 min before drug administration (for baseline assessment) and for 4 h following drug 
administration). This continuous ECG monitoring supports the early detection of adverse
events such as clinically relevant bradycardia, tachycardia, or arrhythmia at the trial site. 
Beyond this clinical evaluation at the trial site, no further data collection or analyses are 
performed based on continuous ECG monitoring.
ECG data from continuous ECG recording will not be transferred to the clinical trial 
database. Abnormal findings during continuous ECG recording will be recorded as AEs if 
judged clinically relevant by the Investigator.
5.2.5
Assessment of other safety parameters
5.2.5.1
Vital signs
Systolic and diastolic blood pressures (BP) as well as pulse rate (PR) or heart rate (heart rate 
is considered to be equal to pulse rate) will be measured by a blood pressure monitor 
(Dinamap Pro 100, GE Medical Systems, Freiburg, Germany) at the times indicated in the 
Flow 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.

APPROPRIATENESS OF MEASUREMENTS
All measurements performed during this trial are standard measurements and will be 
performed in order to monitor subjects’ safety and to determine pharmacokinetic and 
pharmacodynamic parameters in an appropriate way. The scheduled measurements will allow 
monitoring of changes in vital signs, standard laboratory values, and ECG parameters that 
might occur as a result of administration of trial medication. The safety assessments are 
standard, are accepted for evaluation of safety and tolerability of an orally administered drug, 
and are widely used in clinical trials. The pharmacokinetic parameters and measurements 
outlined in Section 5.5 are generally used assessments of drug exposure. The biomarkers and 
measurements outlined in Section 5.6 are of exploratory nature only.
5.5
DRUG CONCENTRATION MEASUREMENTS AND 
PHARMACOKINETICS
Date and clock time of drug administration and pharmacokinetic sampling will be recorded.
Exact time points of plasma sampling will be derived from the 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 parameters 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)

Cmax (maximum measured concentration of the analyte in plasma)

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

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).
The acceptable deviation from the scheduled time for vital signs, ECG and laboratory tests 
will be ± 15 min for the first 4 h after trial drug administration and ± 30 min thereafter.
Starting from 48 h post administration a deviation from the scheduled time for vital signs,
ECG and laboratory tests (including PK) of ±120 min is acceptable.
If several activities are 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 
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 Report 
Planning Meeting.
6.2
DETAILS OF TRIAL PROCEDURES AT SELECTED VISITS
6.2.1

Trial medication will be taken orally by each subject under direct supervision of the 
investigator or 
 designee. Details on treatments and procedures of administration are 
described in Section 4.1.4.
Study participants will be admitted to the trial site in the morning of Day 1 and kept under 
close medical surveillance for at least 34 h following drug administration. The subjects will 
then be allowed to leave the trial site after formal assessment and confirmation of their fitness 
by the investigator or 
 designee. From Day 3 onwards, the study will be performed in an 
ambulatory fashion.
For details on time points and procedures for collection of blood
 samples for PK 
analysis, refer to Flow Chart and Section 5.5.2. 
For details on time points and procedures for collection of blood samples for PD analysis, 
refer to Flow Chart and Section 5.6.2. 
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 withdraw 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 characterised, 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.

7.1
STATISTICAL DESIGN – MODEL
7.1.1
Objectives
The primary objective of this trial is to investigate the safety and tolerability of BI 1323495
by using descriptive statistics for all endpoints comparing active dose groups to placebo. 
The secondary objective is the exploration of the pharmacokinetics (PK) and 
pharmacodynamics (PD) of BI 1323495. 
7.1.2
Endpoints
Safety and tolerability will be determined on the basis of the primary endpoint and the 
additional criteria specified in Section 5.2.1. PK and PD endpoints are specified in Sections 
5.5.1 and 5.6.1, respectively.
7.1.3
Model
Endpoints will be analysed by descriptive statistics. Inferential statistics is not planned (as 
explained in Section 7.2).
Secondary endpoints, as defined in Section 5.5.1.1, will be subjected to analysis of dose 
proportionality by use of the power model.
7.2
NULL AND ALTERNATIVE HYPOTHESES
Safety and tolerability of the different dose groups of BI 1323495 are to be determined on the 
basis of the investigated parameters in comparison to placebo. It is not planned to test any 
statistical hypotheses with regard to these variables in a confirmatory sense. Instead, they will 
be described in their entirety and evaluated by descriptive statistical methods.
Confidence intervals will be computed and will have to be interpreted in the perspective of 
the exploratory character of the study, i.e. confidence intervals are considered as interval 
estimates for effects.
7.3
PLANNED ANALYSES
All individual data will be listed.
Adherence to the protocol (such as inclusion/exclusion criteria, times of measurement, 
compliance with intake of trial medication, treatment dispensing errors, prohibited 
concomitant medication, completeness, and consistency of data) will be checked. Important 
protocol violations (IPVs) will be identified no later than in the Report Planning Meeting and 
provided in the TSAP.

7.3.1
Primary analyses
Analysis of safety and tolerability is described in Section 7.3.3.
7.3.2
Secondary analyses
The secondary parameters (refer to Section 5.5.1) will be calculated according to the BI 
Standard Operating Procedure (SOP) ‘Standards and processes for analyses performed within 
Clinical Pharmacokinetics/Pharmacodynamics’ (001-MCS-36-472). Analyses will be 
performed for parent drug.
Plasma 
 concentration data and parameters of a subject will be included in the
statistical PK analyses if they are not flagged for exclusion due to a protocol violation 
relevant to the evaluation of PK (to be decided no later than in the Report Planning Meeting)
or due to PK non-evaluability (as revealed during data analysis, based on the criteria 
specified below). Exclusion of a subject’s data will be documented in the CTR.
Relevant protocol violations may be:

Incorrect trial medication taken, i.e. the subject received at least one dose of trial 
medication the subject was not assigned to

Incorrect dose of trial medication taken

Use of restricted medications
Plasma 
 concentrations and/or parameters of a subject will be considered as non-
evaluable, if for example:

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.
The PK parameter analysis set (PKS) includes all subjects in the Treated Set (TS) who 
provide at least one PK parameter that was not excluded according to the description above.

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.
To support the analyses of dose proportionality, graphical representations of the data might 
be created. These might include (but are not limited to) individual time-courses of plasma 
concentrations and the (geometric) mean plasma concentration time profiles.
7.3.3
Safety analyses
Safety will be assessed for the endpoints and parameters of interest listed in Section 5.2.1. All 
treated subjects (that is, all subjects who received at least one dose of study drug), will be 
included in the safety analysis. For additional analyses sets used in the ECG evaluation see 
TSAP for further details. Safety analyses will be descriptive in nature and will be based on BI 
standards. No hypothesis testing is planned.
Treatments will be compared in a descriptive way. The placebo control group in the safety 
evaluation will consist of all placebo treated subjects, regardless of the dose group in which 
they were treated. 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’.
The REP for BI 1323495, the time interval when measurable drug levels or PD effects are 
still likely to be present after administration, is not known for this first-in-human trial.
Therefore, all AEs with an onset between start of treatment and the end of trial examination
(last per protocol contact) will be considered on treatment.
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 intake of trial medication will be 
assigned to 'screening' and those between trial medication intake until the end of trial visit 
will be assigned to the treatment period. These assignments including the corresponding time 
intervals will be defined in detail in the TSAP. Please note that AEs occurring after the last 
per protocol contact but entered before database lock will be reported to drug safety only and 
will not be captured in the trial database.
Additionally, further treatment intervals (analysing treatments) may be defined in order to 
provide summary statistics for time intervals, such as combined treatments, on-treatment 
totals or periods without treatment effects (such as screening and post-study intervals).
Adverse events will be coded using the Medical Dictionary for Regulatory Activities 
(MedDRA). Frequency, severity, and causal relationship of AEs will be tabulated by 
treatment, system organ class, and preferred term. SAEs, AESIs (see Section 5.2.2.1), and 
other significant AEs (according to ICH E3) will be listed separately. 
Laboratory data will be compared to their reference ranges. Values outside the reference 
range as well as values defined as clinically relevant will be highlighted in the listings. 
Additionally, differences from baseline will be evaluated.
Vital signs or other safety-relevant data observed at screening, baseline, during the course of 
the trial and at the end-of-trial evaluation will be assessed with regard to possible changes 
compared to findings before start of treatment.
 
 
 
7.3.4
Preliminary PK analyses
A preliminary analysis of PK parameters (AUC0-24 and Cmax of BI 1323495) provided as 
individual values and geometric means will be performed for

DG 1 before proceeding to DG 3

DG 1-2 before proceeding to DG 4

DG 1-4 before proceeding to DG 5

DG 1-5 before proceeding to DG 6

DG 1-6 before proceeding to DG 7

DG 1-7 before proceeding to DG 8
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.

In contrast to the final PK/PD calculations, the preliminary analysis will be based on planned 
sampling times rather than on actual times, regardless of whether actual times were within the 
time windows or not. Therefore, minor deviations of preliminary and final results may occur. 
The preliminary analysis will provide individual and mean concentration/effect-time profiles 
and summary statistics of individual values without subject identification. The preliminary 
results will be distributed to the Investigator and the trial team. 
Depending on the results of available preliminary PK/PD analyses, the tolerability and safety 
of the compound, and changes of dosing schedule (e.g. additional intermediate doses) 
additional PK/PD preliminary analysis may be performed based on the request of the Trial 
Clinical Monitor, the investigator, or Trial Clinical Pharmacokineticist. No formal 
preliminary PK report will be written.
No inferential statistical interim analysis is planned. However, after each dose group the 
investigator (or 
 deputy) is allowed to postpone further dose progression until a 
preliminary analysis of the data already obtained has been performed.
The pharmacokinetic parameters AUC0-24 and Cmax for BI 1323495 will be calculated 
according to the BI SOP
 
The non-compartmental analysis 
will be performed using the validated software program 
 A 
quality check of the interim data will be performed. 
 
 
 
 
Available 
information on dose linearity from preceding dose groups will be considered when estimating 
Cmax and AUC values to be expected for the next higher dose to be administered.
7.3.5
Pharmacokinetic analyses
The pharmacokinetic parameters listed in Section 5.5.1 for BI 1323495 will be calculated 
according to the BI SOP 
 
Subjects who are not included in the PKS (refer to Section 7.3.1) will be reported with their 
individual plasma
 concentrations and individual pharmacokinetic parameters; 
however, they will not be included in descriptive statistics for plasma
 concentrations, 
pharmacokinetic parameters or other statistical assessment.
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).

Biomarker analysis
The biomarker parameters listed in Section 5.6 will be evaluated according to the BI SOP 
Graphical representations versus time and descriptive statistics will be provided for above 
mentioned biomarkers as well as for raw data thereof. If applicable, a statistical model will be 
applied to the biomarker data. Biomarker assessments might be used to establish a PK/PD 
relationship. Further details will be provided in the TSAP.
7.4
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 
Drug concentration data identified with NOS (no sample available), NOR (no valid result), 
NOA (not analysed), or BLQ (below the lower limit of quantification) will be displayed as 
such and not replaced by zero at any time point (this rule also applies to the lag phase,
including the pre-dose values). 
7.4.3
Pharmacokinetic parameters
Handling of missing PK data will be performed according to the relevant SOP of the Sponsor 
For the non-compartmental analysis, concentration data identified with NOS, NOR, or NOA 
will generally not be considered. Concentration values in the lag phase identified as BLQ will 
be set to zero. All other BLQ values of the profile will be ignored. The lag phase is defined as 
the period between time zero and the first time point with a concentration above the 
quantification limit.
7.5
RANDOMISATION
Each dose group will be divided into three cohorts. The subjects of the first and second 
cohorts will not be randomised to maintain a treatment sequence of active-placebo-active-
active due to safety reasons. In the third cohort of each dose level the subjects will be 
assigned to active or placebo treatment using a 3:1 allocation ratio.
The sponsor will arrange for the randomisation as well as packaging and labelling of trial 
medication. The randomisation list will be generated using a validated system, which 
involves a pseudo-random number generator and a supplied seed number so that the resulting 
allocation is both reproducible and non-predictable.

The randomisation list will contain additional blocks to allow for subject replacement (refer 
to Section 3.3.5).
7.6
DETERMINATION OF SAMPLE SIZE
It is planned to include a total of 64 subjects in this trial. The planned sample size is not based 
on a power calculation. The size of 8 subjects per dose group (6 on active treatment, and 2 on 
placebo) is commonly used in single-rising dose studies of the present type and is in general 
considered as sufficient for the exploratory evaluation of single dose safety and 
pharmacokinetics (R95-0013).
Additional subjects may be entered to allow testing of additional doses on the basis of 
experience gained during the trial conduct (e.g. preliminary PK data), provided the planned 
and approved highest dose will not be exceeded and none of the stopping criteria apply. Thus, 
the actual number of subjects entered may exceed 64, but will not exceed 80 subjects entered.
