BENEFIT - RISK ASSESSMENT
1.4.1
Benefits
Participation in this clinical trial is without any (therapeutic) benefit for healthy subjects. 
Their participation in the study, however, is of major importance for the development of a 
new orally available drug, 
 
1.4.2
Risks
Trial subjects are exposed to risks related to the exposure to the trial medication and to risks 
of the study procedures.
At the time of completion of EM DG 2 in this trial, the COVID-19 pandemic emerged with 
worldwide impact on daily life. To allow for thorough evaluation of potential additional risks 
to trial participants in the course of this pandemic, the trial was temporarily put on hold after 
completion of EM DG 2 and prior to the start of EM DG 3. Potential additional risks for 
study participants with regard to COVID-19 have been evaluated and risk management 
measures implemented in ctp version 4.0 (see Sections 1.4.2.1.1 and 1.4.2.3)
1.4.2.1
Risks related to study medication (Investigational Medicinal Product BI 1323495)
Risk factors may derive from particular knowledge or the lack thereof, regarding the mode of
action, the nature of the target, and/or findings in non-clinical safety studies.

1.4.2.1.4
Patient data
The substance has not been administered to patients so far.
1.4.2.1.5
Drug-induced liver injury
Although rare, a potential for drug-induced liver injury (DILI) is under constant surveillance 
by sponsors and regulators. Therefore, this trial requires timely detection, evaluation, and 
follow-up of laboratory alterations in selected liver laboratory parameters to ensure subjects´ 
safety. Laboratory findings of 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 findings 
of elevations of ALT and/or AST ≥10 fold ULN constitute a hepatic injury alert, and a trial 
subject showing these lab abnormalities needs to be followed up according to the ‘DILI 
checklist’ provided in the ISF. See also Section 5.2.6.1.4, adverse events of special interest.
1.4.2.2
Risks related to microdose midazolam
The evaluation of a potential CYP3A4 interaction with BI 1323495 using a microdose of 
midazolam is acceptable. The administered dose is 1/100th of a therapeutic dose and not 
expected to have any pharmacological effects. Microdoses of midazolam have been
administered orally as a microdose in previous clinical studies without any reports of AEs 
[R17-3022, R17-3023]. Therefore, subjects are not exposed to undue risks. Also, the safety 
and tolerability evaluation of BI 1323495 should not be influenced.
1.4.2.3
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, and can cause syncopation. 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 be less than 
500 ml and thus not exceed the volume of a normal blood donation (500 mL). No health-
related risk to healthy subjects is expected from blood withdrawals.
During Covid-19 pandemic, within the usual phase I settings, where subjects stay stationary 
at the site for several days in small groups, there is a potential risk for spreading the infection 
within the group/to the site staff, if an infected subject was enrolled into the trial. Also, there 
are trial procedures, e.g. collecting blood samples, recording of ECG, or assessing vital signs, 
that are impossible to perform from a distance of 1.5 to 2 meters, which is the generally

recommended distance to keep between humans, in order to prevent the transmission of 
SARS-CoV-2.
Risk mitigation:

A risk management plan has been set up at the site detailing specific cautionary measures, 
e.g. hygiene rules, wearing of face masks and physical distance which is filed in the ISF. 

In addition, a screening on SARS-CoV-2 has been implemented, to be performed as part 
of the safety assessments on Day -4 to -2. Subjects positive in the SARS-CoV-2 test will 
be informed about the test result and that they are not eligible to the trial in accordance to 
exclusion criterion #24, prior to coming to the site for stationary admission.

In case COVID-19 is suspected in a subject during trial participation, SARS-CoV-2 
testing is to be initiated without delay to enable treatment discontinuation according to the 
extended withdrawal criteria, i.e., based on a confirmed COVID-19 infection (see Section 
3.3.4.1).
1.4.3
Discussion
The following general safety measures are planned to mitigate potential risks associated with 
the IMP BI 1323495:

Dose selection for this trial is based on PK predictions derived from clinical data of a 
single rising dose trial (1405-0001) and a food effect trial (1405-0007), as well as
preclinical data (see IB and Section 4.1.2).
 

exposures may exceed exposures that have as yet been observed in healthy volunteers in
the single rising dose trial 1405-0001. In that trial, due to the less than linear increase of 
exposures with dose, the expected human therapeutic exposure range could just be 
reached for Cmax, without establishing a safety margin, and could not be reached for 
AUC0-24, in UGT2B17 EMs. Therefore, careful dose escalation (see Section 3.1) will be 
used to explore exposures above the limited SRD exposures. This will allow assessment 
of higher exposures that may be required for efficacy (also covering AUC and Cmin). Dose

escalations will occur in the setting of a multiple rising dose trial under clinically tightly 
monitored conditions, in a fashion similar to that obtained in the first in man study 1405-
0001.

A Dose Escalation Committee (DEC) will be constituted which will ensure appropriate 
and documented safety review before deciding on each dose escalation step (see Sections 
3.1 and 8.7). Only if the respective dose of BI 1323495 was safe and showed acceptable 
tolerability, also considering gender differences, and if no stopping criterion was met (see 
Section 3.3.4.2) within a dose group, the next dose group will be started at least 7 days 
after last subject completed End of Treatment of the previous dose group.

Estimation of exposures for subsequent dose groups will be done based on preliminary 
PK values of preceding dose groups 
 

To reduce PK variability, UGT2B17 EMs and PMs will be included in separate parts 
(Part I: EMs; Part II: PMs) of the study and will be administered different dose ranges. 

Part of the subjects within each dose group will be treated with placebo, which is 
considered standard in phase I trials, to allow for a reliable assessment of safety and 
tolerability.

For safety reasons, each dose group of 12 subjects in Part I (9 on active, 3 on placebo) 
and 8 subjects in Part II (6 on active and 2 on placebo) will be divided into two cohorts. 
The first (“sentinel”) cohort will consist of 4 subjects for Part I and Part II (3 on active, 1 
on placebo). The second cohort will consist of 8 subjects in Part I (6 on active, 2 on 
placebo) and 4 subjects in Part II (3 on active, 1 on placebo). These two cohorts will be
separated by at least 7 days (between first dose of the last subject of 1st cohort and first 
dose of the first subject of 2nd cohort) which is expected to cover the period until 
pharmacokinetic steady state is reached. Both cohorts will be dosed in a randomised 
fashion.

Extensive safety laboratory assessments will be performed (see Section 5.2.3), 
particularly including parameters to monitor liver and renal function as well as infection.

A thorough ECG monitoring comprised of repetitive 12-lead ECGs will be performed.


Potential effects of BI 1323495 on embryo-fetal development have not yet been assessed, 
and no data are available from its use in pregnant women. Therefore BI 1323495 should 
not be administered to pregnant women and should not be used in women of child-
bearing potential without adequate contraception.

Upon start of treatment until Day 12, subjects will stay at the site being kept under 
medical surveillance under stationary conditions, and monitored for both expected and 
unexpected adverse events (see Flow Chart 1/2/3/4).

Healthy subjects up to ≤ 70 years of age will be enrolled in this trial. Accordingly, 
exclusion criteria have been defined in order not to expose subjects within this age range 
to a particular risk due to the presence of concomitant conditions. In particular, subjects 
with a history of cardiovascular disease or evidence of clinically relevant ECG alterations 
will be excluded from participating in this trial. Neither non-clinical toxicity testing nor 
clinical safety in the first-in-human trial 1405-0001 have revealed a potential of 
BI 1323495 to be associated with cardiovascular adverse effects. The general risk-
mitigation measures in this trial, i.e., step-wise dose escalations, dosing in two subcohorts 
within each dose level, and close medical surveillance during stationary stay during the 
entire treatment period, also serve to ensure that healthy subjects up to ≤ 70 years of age 
will not be exposed to any undue risks.

Potential risks for the subject in relation to the COVID-19 pandemic situation have been 
evaluated together with the principle investigator. With regard to study treatment, no 
relevant impact is expected on the subject’s health condition (like e.g. increased 
susceptibility to infections, immune suppression, or impaired lung function). In the very 
unlikely case that despite all implemented measures a COVID-19 case occurs in a trial 
subject while in the study, the withdrawal criterion for subjects experiencing an infection 
has been extended to also cover discontinuation of treatment in case of laboratory-
confirmed COVID-19 disease.

To minimize the risk that infected subjects take part in the trial, who might spread the 
infection to others, subjects are only to be admitted to the site for Visit 2 if fulfilling the 
strict criteria laid out by the Robert Koch Institute (RKI) in the current national testing 
strategy regarding admission or re-admission of patients to hospital, see: 
https://www.rki.de, particularly 
https://www.rki.de/DE/Content/InfAZ/N/Neuartiges_Coronavirus/Teststrategie/Nat-
Teststrat.html. This includes a negative PCR test (see Section 5.2.3), and patients need to 
confirm a symptom-free interval of 48 hours. As RKI recommendations may be subject to 
change, current recommendations will be re-assessed on a periodic basis and trial 
procedures adapted accordingly, if applicable.

meetings will be held after completion of dose groups for trial parts I and II, allowing to 
independently decide for each part on further dose escalations. However, the totality of 
clinical safety and pharmacokinetic data available at the respective time point from both trial 
parts will be considered for the dose escalation decision.
Subjects will be enrolled (screened) in the trial once they have signed the informed consent. 
Subjects who are suitable after screening and who still meet the inclusion/exclusion criteria 
will be randomised into the treatment period in which they will receive either BI 1323495 or 
placebo. No concomitant therapy is allowed (restrictions see Section 4.2.2).
A total of 88 healthy male and female subjects will participate in the trial (Part I: 6 sequential 
groups of 12 subjects each, Part II: 2 sequential groups of 8 subjects each). 
Note: with global amendment 6, an intermediate dose of 120 mg bid (DG 6) in EMs was 
added.
Note: with global amendment 7, a 120 mg qd dose group (DG 7) in EMs was added, and 
decision to finally not use the initially planned 300 mg bid dose group (DG 5) in EMs was 
implemented (see Section 4.1.2).
The addition of a dose group for the evaluation of safety findings would require a substantial 
amendment and could only be implemented after approval.
Only one dose is tested within each dose group.
Additionally, the potential for DDI with a CYP3A4 substrate will be assessed in the three 
highest bid dose groups of Part I. This will be conducted in parallel to BI 1323495
administration, using a microdose of midazolam (a sensitive CYP3A4 substrate) administered 
at 2 different time points (on Day -1 and Day 11/EoT) to examine potential CYP3A4
induction effects of BI 1323495.
The following figures show an overview over the visit structure. Detailed schedules of all 
relevant trial activities are provided in the Flow Charts 1, 2 and 3.

For safety reasons, each dose group will consist of 2 cohorts. The trial medication will be 
administered accordingly:
Part I:

Cohort 1: 3 subjects on active treatment and 1 subject on placebo (in total 4 subjects)

Cohort 2: 6 subjects on active treatment and 2 subjects on placebo (in total 8 subjects)
Part II: 

Cohort 1: 3 subjects on active treatment and 1 subject on placebo (in total 4 subjects)

Cohort 2: 3 subjects on active treatment and 1 subject on placebo (in total 4 subjects)
Between start of the last subject of the first cohort and start of second cohort there will be a 
time interval of at least 7 days (see Section 6.2.2). 
Two cohorts (within one dose group) are considered as appropriate based on the clinical data 
from the first-in-man single-rising dose trial that investigated and confirmed the safety of 
single doses up to 600 mg. No acute effects were observed at exposures expected in this trial.
Within each trial part, treatment in the next higher dose group will only be started if the 
treatment in the preceding dose groups was safe and showed acceptable tolerability.
The dose groups to be evaluated are outlined in Table 3.1: 4 below.

3.1.1
Dose Escalation Committee review
The different dose groups will be investigated, within each study part, consecutively in 
ascending order of daily doses, maintaining a time interval of at least 7 days between last 
drug administration in the preceding dose group and first drug administration of the 
subsequent dose group. The decision to proceed to the next dose level, no matter if in Part I 
or Part II of the trial, will be based upon the safety and tolerability data of all preceding dose
levels, which will be assessed by a Dose Escalation Committee (DEC, see Section 8.7). The 
next dose will only be given if, in the documented opinion of the DEC, no safety concerns 
arise in the previous dose groups (i.e. no dose-limiting events occur) and if none of the pre-
specified trial-specific stopping criteria are met (Section 3.3.4.1).
The minimum data set for DEC review consists of the following data:

Adverse events of the current and preceding dose levels (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 change prior to Database Lock).

Results from 12-lead EGG of the current and preceding dose levels.

Vital signs of the current and preceding dose levels.

Clinical laboratory tests of the current and preceding dose levels.

Check of criteria for stopping subject treatment as per Section 3.3.4.

Preliminary PK data 
 from at least 5 subjects on active 
treatment
 
from previous dose group and exposure predictions for 
subsequent dose group, to make sure the next applied dose regimen will not exceed 
the predefined exposure limits.

The DEC will review unblinded data. As the DEC is reviewing data only retrospectively, i.e.,
after the relevant subjects have completed the trial, this is not considered as having impact on 
the Principal Investigator’s blinded assessment of subjects during their trial participation.
Furthermore, an unscheduled safety review by the DEC can be requested anytime for any 
reasonable cause by the Principal Investigator or the sponsor of the study, e.g. because of any
unforeseen adverse events.
3.2
DISCUSSION OF TRIAL DESIGN, INCLUDING THE CHOICE OF 
CONTROL GROUP
This trial will investigate the safety and tolerability as well as pharmacokinetics of multiple 
rising doses of BI 1323495, administered twice daily or once daily together with a meal. As 
the therapeutic exposure range has not been reached following administration of single doses 
in trial 1405-0001 in UGT2B17 extensive metabolizers, 
 
 dose levels in this multiple-rising dose trial have been 
selected to explore necessary exposures in a Phase I setting.
With the rising-dose design, double-blind conditions regarding the subjects' treatment 
allocation (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 potential dose-dependent effects, but this design, also 
involving review of the data from each dose group by a Dose Escalation Committee (see 
Section 3.1.1), is inevitable when sequentially studying ascending doses in order to minimize 
subject risk.
Due to the small number of subjects, the study will not allow for hypothesis testing but will 
allow for gathering safety, PK, and PD data for decision on the definition and possible 
limitation of the number of dose levels to be explored in later clinical development trials.

The control group will be treated with placebo, which is considered standard in phase I trials, 
to allow for a reliable assessment of safety and tolerability and PD.
The group size (9 subjects in Part I and 6 subjects in Part II per active treatment group) is in 
general considered sufficient for the assessment of safety and tolerability as well as for the 
exploratory evaluation of pharmacokinetics, but will only allow for a descriptive analysis of 
pharmacodynamic effects (in Part I) (see Section 7.5). The number of 4 females per dose 
group in Part I (3 on active, 1 on placebo) is considered adequate to allow for an assessment 
of the effect of gender on pharmacokinetic parameters and on safety.
The treatment period of 11 days is considered adequate for collection of safety,
pharmacokinetic, and pharmacodynamic data after multiple dosing at steady state to inform 
subsequent studies along the clinical development path. The treatment period is adequately 
covered by non-clinical toxicology data from animal studies.
A strong PK/PD relationship has been observed in the SRD trial. 
 
3.3
SELECTION OF TRIAL POPULATION
It is planned that 88 healthy subjects will be randomised. Subjects will be recruited from the 
volunteers' pool of the trial site.
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.
No data on reproductive toxicology are available at this time, therefore male subjects will be 
included and female subjects either not of childbearing potential (i.e. postmenopausal or 
surgically sterilised) or women of childbearing potential willing and able to use a highly 
effective method of contraception as described in Section 4.2.2.3. The age range has been 
selected to allow the identification of postmenopausal women for the purpose of stratification 
by gender in the EM dose groups. The defined age range also enables the inclusion of healthy 
subjects representative for the typical age ranges of patients of both targeted indications, i.e., 
COPD and CF, which differ substantially: COPD is a disease of advanced age, with 
populations of typical large clinical trials in COPD having a mean age of > 60 years. Among 
CF patients, on the other hand, only few reach an age of > 50 years. Therefore, in order to 
also cover females of a CF-adequate age range, it is allowed that women of child-bearing 
potential are enrolled if they are willing and able to use adequate, non-hormonal 
contraception methods, as defined in Section 4.2.2.3. This is also expected to facilitate the 
identification of a sufficient number of female subjects to be recruited. The selected age

Withdrawal of subjects from treatment or assessments
Subjects may discontinue trial treatment or withdraw consent to trial participation as a whole
(“withdrawal of consent”) with very different implications; please see Sections 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, an End of Treatment examination followed by an End of 
Study Visit will be performed as indicated in the Flow Chart 1/2/3/4, if possible, and the 
information will be recorded in the CRF.
The decision to discontinue trial treatment or withdraw consent to trial participation and the 
reason must be documented in the subject files and CRF. If applicable, consider the 
requirements for Adverse Event collection reporting (please see Sections 5.2.6.2.1 and 
5.2.6.2).

If it is known that a subject becomes pregnant during the trial, administration of the trial 
medication is to be stopped immediately, and the subject is to be removed from the trial. The 
subject is to be followed until she has given birth or until the end of the pregnancy. The 
subject’s data are to be collected until the end of the trial (last visit of last subject) and 
reported in the CTR. For reporting of pregnancy and associated events, refer to Section 
5.2.6.2.4.
3.3.4.1
Discontinuation of trial treatment
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 (see Section 4.2.2).

The subject can no longer receive trial treatment for medical reasons (such as surgery, 
adverse events, other diseases, or pregnancy).

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.

The subject experiences an infection with SARS-CoV-2 (as confirmed by PCR Test, see 
Section 5.2.3) or an infection requiring systemic antibiotic treatment.
In addition to these criteria, the physician may discontinue a subject 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

outlined in the FC and Section 6.2.3.
3.3.4.2
Withdrawal of consent to trial participation
Subjects may withdraw their consent to trial participation at any time without the need to 
justify the decision.
3.3.4.3
Discontinuation of the trial by the sponsor
Boehringer Ingelheim reserves the right to discontinue the trial at any time for the following 
reasons:
1. Failure to meet expected enrolment goals overall or at a particular trial site.
2. Violation of GCP, the trial protocol, or the contract impairing the appropriate conduct of 
the trial.
3. The sponsor decides to discontinue the further development of the investigational 
product.
4. New toxicological findings or serious adverse events invalidate the earlier positive 
benefit-risk-assessment.

5. Dosing will be stopped upon occurrence of a serious adverse reaction or of severe non-
serious adverse events considered as drug related by the investigator in 2 subjects on 
active treatment of the same dose group. No further subjects will be treated without 
thorough re-evaluation of the benefit-risk ratio.
6. Dosing will be stopped if at least 2 subjects on active treatment at one dose level have
relevant individual QT prolongations, i.e. a QTc increase of greater than 60 ms from 
baseline or absolute QT or QTc greater than 500 ms, as confirmed by a repeat ECG 
recording.
7. Dose escalation will be stopped if, based on preliminary PK results of preceding dose 
groups, the estimated systemic exposure (group gMean values) of the next dose level is 
expected to exceed a Cmax of 1900 nM or an AUC0-24 of 11500 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.
8. Dose escalation will be stopped (within the relevant study Part, I or II) if at least one 
subject of the preceding dose group exceeds individual exposures of a Cmax of 1900 nM or 
an AUC0-24 of 11500 nM*h.
The investigator / the trial site will be reimbursed for reasonable expenses incurred in case of 
trial termination (except in case of the second reason).
3.3.5
Replacement of trial participants
In case some subjects do not complete the trial or there is not a sufficient number of subjects 
on active treatment within one dose group (see Section 3.1), the Clinical Trial Leader 
together with the Trial Clinical 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 or she 
replaces.
Subjects withdrawn due to drug-related adverse events will not be replaced. In addition, the 
subjects will not be replaced in the following cases:
1.
If a subject within the first cohort discontinues trial medication prior to reaching the 
decision point (at PK steady state) for the initiation of the second cohort of the current 
dose group, the safety decision would still be valid based on three subjects (of which 
at least 2 have to be on active treatment). No replacement is necessary to complete the
first cohort. 
2.
Within a dose group, subjects will not be replaced, if at least 5 subjects on active 
treatment (for Part I: at least two per each gender) complete the trial.

Midazolam
For testing the potential of BI 1323495 to induce CYP3A, an oral dose of 75 µg midazolam 
has been chosen to be administered once in the absence of BI 1323495 and once at PK steady 
state following multiple doses of BI 1323495. This dose is within the definition of a 
microdose (1/100th of the therapeutic dose, or 100 µg, whichever is smaller). Since 
midazolam exposures have been shown to be dose proportional over the microdose-to-
therapeutic-dose range, the microdose is considered adequate to accurately assess the CYP3A 
induction potential, while remaining below a pharmacologically active and toxicologically 
relevant concentration of midazolam.
For oral administration of midazolam, the preparation of the dose by dilution of the marketed 
solution for IV administration has been selected instead of preparation from the marketed oral 
solution. This decision was made as the preparation of a microdose of 75 µg with adequate
precision and reproducibility requires dilution from the more highly concentrated original 
solution. Whereas data regarding the stability and compatibility of a dilution prepared from 
the solution for IV administration are available, this is not the case for a dilution prepared 
from the solution for oral administration. Furthermore, the IV solution contains midazolam in 
isotonic saline solution, while the oral solution has added excipients, which would result in 
additional elements of risk. Finally, there is the aspect of feasibility, whereby the oral

solution would need to be diluted 1:400, which may not be possible to be accurately 
achieved, while the IV solution requires a dilution of only 1:200. The IV solution of 
midazolam has been successfully diluted and administered orally as a microdose in previous 
clinical studies without any reports of AEs.
4.1.3
Method of assigning subjects to treatment groups
Prior to 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 (2 cohorts per 
dose group) according to their temporal availability.
In this trial a sentinel cohort design is used within each Dose Group. As soon as enough 
subjects have been allocated to the first cohort, the following subjects will be allocated to the 
second cohort of the respective dose group. Therefore, the allocation of subjects to cohorts is 
not influenced by trial personnel, but only by the subjects’ temporal availability.
Prior to first administration of trial medication, eligible subjects will be randomised to receive 
active compound (BI 1323495) or matching placebo in a 3:1 ratio according to a 
randomisation plan. 
The list of subject and medication numbers will be provided to the trial site in advance. The 
allocation of subjects to trial subject numbers will be performed prior to the first 
administration of trial medication. For this purpose, the subjects will be allocated to a subject
number by the method ‘first come-first served’. Once a subject number has been assigned, it 
cannot be reassigned to any other subject.
The randomisation procedure is described in Section 7.5.
Subjects will first be randomised into Dose Group 1. Randomisation into a following dose 
group will only be possible after the DEC has cleared the next dose group for randomisation
after assessment of all available data from the subjects of the preceding dose group (see
Section 3.1). 
In- and exclusion criteria are applicable for all dose groups. 
4.1.4
Drug assignment and administration of doses for each subject
The treatments to be evaluated are outlined in Table 4.1.4:1 below. The number of units for 
placebo corresponds to the number of units of the respective dose group of the active 
substance.

On Day 11, Subjects will receive a single dose in the morning only. On all other trial days,
BI 1323495 will be administered bid (except for 120 mg qd dose group).
For safety reasons, each dose group will consist of 2 cohorts. The trial medication will be 
administered accordingly:

Cohort 1 (“sentinel”): 3 subjects on active treatment and 1 subject on placebo (in total 4 
subjects)

Cohort 2: For Part I, 6 subjects on active treatment and 2 subjects on placebo (in total 8 
subjects); for Part II, 3 subjects on active treatment and 1 subject on placebo (in total 4 
subjects)
Between start of last subject of cohort 1 and start of cohort 2 there will be a time interval of at 
least 7 days. This ensures that the safety of subjects in cohort 1 who have reached 
pharmacokinetic steady state of BI 1323495
 will have been evaluated before subjects 
of cohort 2 start treatment.
In case safety data cannot be assessed for all 4 subjects of the first cohort of a dose group, 
safety data of at least two subjects on active study drug must be available for safety 
evaluation.

In the following paragraphs of this chapter, information regarding the evening dose (time, 
food intake etc.) is applicable for all bid dose groups. For the DG 7 with 120 mg qd, drug 
administration takes place only in the morning.
Subjects who qualify will be randomised to either BI 1323495 or placebo and will be 
instructed to self-administer the trial medication depending on the dose group that is open for 
randomisation at that timepoint. The morning dose will be administered to the subjects at the 
site under supervision of authorized site staff. Generally, subjects should take the study drug
while in a standing or sitting position, as an oral dose together with about 240 mL of water.
On first day of treatment (Day 1) and last day of treatment (Day 11), where PK profile 
sampling takes place, administration of BI 1323495 and administration of midazolam (Day -
1, Day 11, Part I DG 3, 4, and 6) in the morning will be performed following a standardized
breakfast, which is to start and be completed within 30 minutes before the scheduled dosing. 
On all other treatment days and in the evening of Day 1, subjects should take the study 
medication with food, preferably within 30 min after a meal. On treatment days, breakfast 
will be provided 30 minutes prior to the morning dose administration and dinner will be 
provided 30 minutes prior to the evening dose administration.
Subjects should take their morning doses on all treatment days at the same time as on the first 
day, +/- 1 hour. The evening dose should be taken 12 hours +/-1 hour after the scheduled time 
of the morning dose.
Following the first administration of trial medication, subjects will stay in inhouse 
confinement until Day 12. During the first 2 h after drug administration, and in Part I DG 3, 
4, and 6 in the first 2 h after midazolam administration on Day -1, 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 trial is designed double-blind with regard to the subjects and the investigator (as well as 
the research staff at the trial site) in order to eliminate observer or performance bias. This 
means avoiding systematic differences in assessments regarding the subject’s treatment 
(active or placebo). According to the rising dose design, the current dose level will be known 
to subjects and investigators.
At the trial site, access to the randomisation schedule is restricted to unblinded pharmacist. 
The unblinded pharmacist together with a further staff member will assign the medication 
numbers to the random numbers. Access to the codes will be controlled and documented by a 
signed confidentiality statement, which will be stored in the TMF. Persons directly involved 
in the clinical conduct of the trial will not have access to the treatment allocation prior to 
database lock.
Regarding the sponsor, the database of this trial will be handled open-label, meaning that the 
trial functions of the sponsor are unblinded (including clinical trial leader, clinical trial 
manager, data manager, statistician, bioanalyst, pharmacokineticist, pharmacometrician, drug

metabolism scientist as well as dedicated CRO personnel if not involved in the clinical 
conduct of the trial). The objective of the trial is not expected to be affected.
DEC Members will receive unblinded data, for details see Section 3.1.1.
Within the central ECG lab, the staff involved with interval measurements and morphological 
analyses will be blinded with respect to the treatment and also with regard to the recording 
date and time as well as planned time points of the ECGs. The interval measurements for a 
given subject will be performed in a random and blinded sequence by a single technician. No 
more than two different blinded readers will evaluate the ECGs of the study.
4.1.5.2
Unblinding and breaking the code
Emergency unblinding will be available to the investigator via contact to the unblinded 
pharmacist or, in exceptional case of non-availability, by calling the emergency unblinding 
provider contracted for the trial (Global Emergency Unblinding & Medical Support in 
Clinical Trials). Instructions will be provided in the ISF, and subjects will receive the contact 
information on their Trial Identification Card. It must only be used in an emergency situation 
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. The sponsor 
must be informed immediately. The reason for unblinding must be documented in the source 
documents and/or appropriate CRF page along with the date and the initials of the person 
who unblinded.
Due to the requirements to report Suspected Unexpected Serious Adverse Reactions 
(SUSARs), it may be necessary for a representative from
to 
access the randomisation code for individual subjects during trial conduct. The access to the 
code will only be given to authorised Pharmacovigilance representatives and not be shared 
further.

Restrictions
4.2.2.1
Restrictions regarding concomitant treatment
In principle, no concomitant therapy is allowed. In particular, drugs must be avoided which 
are known to induce CYP3A4. Strong inhibitors of CYP3A4/P-gp have to be avoided in Part 
I, since a modest effect of the strong CYP3A4/P-gp inhibitor itraconazole on the PK of 
BI 1323495 has been observed (see Section 1.2.4). For PM subjects participating in Part II of 
the trial, inhibitors of CYP3A4/P-gp have to be avoided in general.
Live or live-attenuated vaccine should be avoided during the trial.
All concomitant therapy will be recorded (including time of intake on study days) on the 
appropriate pages of the CRF. 
4.2.2.2
Restrictions on diet and life style
On Day 1 and Day 11 where PK profile sampling is performed, while admitted to the trial 
site, the subjects are restricted from consuming any other foods or beverages than those 
provided by the site staff. Standardised meals will be served at the time points described in 
Flow Chart 1/2/3/4. A standardized normal caloric breakfast (e.g., a roll with cheese or 
sausage, including some dietary fat) should be served and finished within 30 minutes prior to 
dose administration. In addition, in Part I DG 3, 4, 6, and 7, breakfast will be served 30 
minutes before midazolam intake on Day -1 and should be finished within 30 minutes prior to 
dose administration.
In the evening of Day 1 and on Days 2 to 10, drug intake should occur with food. Breakfast 
will be provided 30 minutes prior to the morning dose administration and dinner will be 
provided 30 minutes prior to the evening dose administration (for DG 7 with qd dosing, 
instructions regarding evening dose are not applicable).
On Days 1 and 11, from 1 h before drug intake until lunch, fluid intake is restricted to the 
water administered with the drug, and an additional 240 mL of water served at 2 h and 4 h 
post-dose (mandatory for all subjects). From lunch until 24 h post-dose, total fluid intake is 
restricted to 3.0 litres.
On Day -1 in Part I DG 3, 4, and 6, from 1 h before midazolam intake until 4 h after 
midazolam intake, fluid intake is restricted to the water administered with midazolam and an 
additional 240 mL of water served at 2 h and 4 h after midazolam (mandatory for all 
subjects).
During the days of urine collection, total fluid intake should be at least 1.5 litres and should 
not exceed 3.5 litres.

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 the administration of trial medication until after the last PK 
sample is collected.
Methylxanthine-containing beverages or foods (such as coffee, tea, cola, energy drinks, and 
chocolate) are not allowed from 4 h before until 4 h after each administration of trial 
medication.
Smoking is not allowed during in-house confinement while admitted to the trial site.
Excessive physical activity (such as competitive sport) should be avoided starting 7 days 
before the administration of trial medication until the EoS Visit. 
Direct exposure to the sun or exposure to solarium radiation should be avoided during the 
entire study.
4.2.2.3
Contraception requirements
Women of child-bearing potential (WOCBP) must use one of the following highly effective 
methods of birth control per ICH M3 (R2) that result in a low failure rate of less than 1% per 
year when used consistently and correctly, from at least 30 days before the first 
administration of trial medication until 14 days after trial completion:

Use of intrauterine device (IUD) plus condom (Note: intrauterine hormone-releasing 
systems (IUS) will not be allowed).

Sexual abstinence: This is defined as refraining from heterosexual intercourse during 
the entire period of risk associated with the study treatments. The reliability of sexual 
abstinence needs to be evaluated in relation to the duration of the clinical trial and the 
preferred and usual lifestyle of the subject. Periodic abstinence e.g. calendar, 
ovulation, symptothermal, post-ovulation methods and withdrawal are not acceptable.

A vasectomised sexual partner who received medical assessment of the surgical 
success (documented absence of sperm) (see Section 3.3.2).
The investigator should take care to inform WOCBP that hormonal contraception methods 
are not considered highly effective in this trial. However, female subjects regularly taking
hormonal contraception are not required to interrupt administration during the trial, as long as 
they are aware that the effectiveness of hormonal contraception may be reduced (see also 
Section 1.2.4), and another method (as described above) has to be used in addition.
Men able to father a child must use highly effective methods of birth control per ICH M3 
(R2) that result in a low failure rate of less than 1% per year when used consistently and 
correctly. A list of contraception methods meeting these criteria is provided in the subject 
information.
4.3
TREATMENT COMPLIANCE
Compliance will be assured by administration of all trial medication in the study centre under 
supervision of the investigating physician or a designee. Subjects who are non-compliant (for 
instance, who do not appear for scheduled visits or violate trial restrictions) may be removed

The results must be included in the source documents available at the site. 
5.2.2
Vital signs
Vital signs will be evaluated at the time points specified in the Flow Chart 1/2/3/4, prior to 
blood sampling.
This includes systolic and diastolic blood pressure and pulse rate (electronically or by 
palpation count for 1 minute) in a supine position after at least 5 minutes of rest. The results 
must be included in the source documents available at the site.
Aural body temperature will be measured at the time points indicated in the Flow Chart
1/2/3/4.
5.2.3
Safety laboratory parameters
Safety laboratory parameters to be assessed are listed in Tables 5.2.3: 1 and 5.2.3: 2. For the 
sampling time points please see the Flow Chart 1/2/3/4. Reference ranges will be filed in the 
ISF.
Blood and urine samples will be analysed by the local laboratory of the site. Laboratory data 
will be collected and captured in the eCRF. Manual differential white blood cell count or 
urine sediment examinations will only be performed if there is an abnormality in the 
automated blood cell count or if erythrocytes, leukocytes, nitrite, or protein are abnormal in 
the urinalysis, respectively.
It is the responsibility of the investigator to evaluate the laboratory reports received from the 
local laboratory. Clinically relevant abnormal findings as judged by the investigator will be 
reported as adverse events (please refer to Section 5.2.6).
In case the criteria for hepatic injury are fulfilled, a number of additional measures will be 
performed (please see Section 5.2.6.1 and the DILI Checklist provided in the ISF). In this 
case, the amount of blood taken from the subject concerned will be increased due to the
additional sampling.

12 –lead resting ECG
Recording
Twelve-lead resting ECGs (I, II, III, aVR, aVL, aVF, V1 - V6) will be recorded using a 
computerised system at the time points given in the Flow Chart 1/2/3/4. Electrode placement 
will be performed according to the method of Wilson, Goldberger and Einthoven modified by 
Mason and Likar (hips and shoulders instead of ankles and wrists). Precise electrode 
placement will be marked with an indelible mark on the skin to allow reproducible placement 
throughout the study.
To achieve a stable heart rate at rest and to assure high quality recordings, the site personnel 
will be instructed to assure a relaxed and quiet environment, so that all subjects are at 
complete rest.
All ECGs will be recorded for a 10 sec duration after subjects have rested for at least 5 min in 
a supine position. ECG recording will always precede all other study procedures scheduled 
for the same time (except for blood drawing from an intravenous cannula that is already in 
place) to avoid compromising ECG quality.
ECGs will be recorded as single ECGs or as triplicate ECGs (i.e. three single ECGs recorded 
within 180 sec) as indicated in the Flow Chart 1/2/3/4. Recording time points may be adapted 
based on information obtained during the trial. Such changes would be implemented as non-
substantial amendment.
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 system provided by 
. Screening 
and EoS ECGs will not be transferred to central ECG lab.
Data transfer
For time points specified in the Flow Chart 1/2/3/4, ECGs will be transferred electronically to 
the central ECG lab (
) for evaluation.
In case of repeat ECGs due to quality reasons, only the repeated ECG recordings will be 
transferred to the central ECG lab.
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 (see TMF).

Evaluation
a) Central ECG laboratory
Central ECG lab evaluation will be performed for the first of three replicate ECGs per 
time point as specified in the Flow Chart 1/2/3/4.
RR and QT intervals will be determined semi-automatically, whereas PR, QRS 
intervals, and QRS-axis are measured automatically by a validated GE 12-SL-
algorithm or equivalent.
Heart rate (HR) and the QT interval corrected for HR (QTc, e.g. QTcF and QTcB) 
will be determined by the sponsor (see TSAP for details).
All semi-automatic interval measurements in one subject will be performed on the 
same lead. The intervals will be measured from four cardiac cycles (beats) in lead II. 
If lead II shows a flat T wave or is not measurable for any reason, lead V5 will be 
used, or if that lead is not measurable, then lead I will be used. The lead actually used 
will be reported in the CTR.
For automatic interval measurements no lead will be provided. After quality control, 
the fiducial point markings will be reviewed by the cardiologist assigned to the study.
For blinding arrangements see Section 4.1.5. 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 the 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 (see Section 3.3) of a subject and for the assessment of 
cardiac safety during the study, the QT and QTcB values generated by the 
computerised ECG system or their manual corrections by the investigators will be 
used.
In doubtful cases, ECGs may be sent upfront (i.e. prior to the regular data transfer) for 
cardiologic assessment by the central lab. In this case, these centrally measured results 
would overrule any other results obtained.
Abnormal findings, irrespective of whether they originate from central or local evaluation, 
will be reported as AEs (during the trial) or baseline conditions (at screening) if judged 
clinically relevant by the investigator.
Any ECG abnormalities will be monitored carefully and, if necessary, the subject will be 
removed from the trial and will receive the appropriate medical treatment.

5.2.5
Other safety parameters
This section is not applicable.
5.2.6
Assessment of adverse events
5.2.6.1
Definitions of AEs 
5.2.6.1.1
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 pre-exist prior to trial inclusion, they will be considered as 
baseline conditions and should be collected in the eCRF only.
5.2.6.1.2
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 
on appropriate medical judgement 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. 
5.2.6.1.3
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 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, 
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.
5.2.6.1.4
Adverse events of special interest
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 see 
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: 

an elevation of AST (aspartate transaminase) and/or ALT (alanine transaminase) ≥3 fold 
ULN combined with an elevation of total bilirubin ≥2 fold ULN measured in the same 
blood draw sample, or

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 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.
5.2.6.1.5
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.
5.2.6.1.6
Causal relationship of AEs
Medical judgement 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.
5.2.6.2
Adverse event collection and reporting
5.2.6.2.1
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 
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 1/2/3/4. 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 the individual subject’s end of trial: 
o
All AEs (serious and non-serious) and all AESIs.
o
The only exception to this rule are AEs (serious and non-serious) and AESIs in 
Phase I trials in healthy volunteers, when subjects discontinue from the trial due to 
screening failures prior to administration of any trial medication. In these cases, 
the subjects’ data must be collected at trial site but will not be entered in the CRF 
or trial database and will not be reported in the CTR.

After the individual subject’s end of trial: 
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.
5.2.6.2.2
AE reporting to the sponsor and timelines
The investigator must report SAEs, AESIs, and non-serious AEs which are relevant for the 
reported SAE or AESI, on the BI SAE form 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.
5.2.6.2.3
Information required
All (S)AEs, including those persisting after individual subject’s end of trial must be followed 
up until they have resolved, have been assessed as “chronic” or “stable” , or no further 
information can be obtained.
5.2.6.2.4
Pregnancy
In rare cases, pregnancy might occur in a clinical trial. Once a subject has been enrolled in 
the clinical trial and has taken trial medication, the investigator must report any drug 
exposure during pregnancy in a trial participant immediately (within 24 hours) by means of 
Part A of the Pregnancy Monitoring Form to the sponsor’s unique entry point.
Similarly, potential drug exposure during pregnancy must be reported if a partner of a male 
trial participant becomes pregnant. 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 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.

DRUG CONCENTRATION MEASUREMENTS AND 
PHARMACOKINETICS
5.3.1
Assessment of pharmacokinetics
Date and exact clock time of drug administration and pharmacokinetic sampling for 
BI 1323495 and Midazolam will be recorded in the eCRF.
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.
If a subject has to be withdrawn from treatment at one of the above mentioned time points 
and the PK sample was already obtained, this PK sample might be registered as EOS sample 
instead. It will be collected and analysed accordingly.

BI 1323495, Midazolam and 1-OH midazolam
After completion of the trial, the plasma samples may be used for further methodological
investigations, e.g. for stability testing, assessment of metabolites. However, only data related
to the analyte and/or its metabolite(s) including anti-drug antibodies (if applicable) will be
generated by these additional investigations. The study samples will be discarded after
completion of the additional investigations but not later than 5 years upon the final study
report has been signed.
5.3.2.2
Plasma sampling for metabolism analysis
Additional EDTA plasma samples for the identification of drug metabolites will be
investigated in the 150 mg bid EM dose group (DG4 in Part I) and 30 mg bid PM dose group 
(DG2 in Part II) and will be pooled per dose group.
Based on the knowledge gained during the trial conduct, e.g. from preliminary PK results, the 
dose group may be changed to a different one. The change would be implemented via a non-
substantial CTP Amendment.
The blood samples will be drawn in parallel to PK samples at Day 11 including the 24 h 
sample (see Flow Chart 2/3). At each of these time points, approx. 3 ml blood will be needed 
for metabolite analysis. The blood samples will be processed in the same way as the PK 
samples described in the lab manual.
Only data related to the parent compound and its metabolites will be acquired. Evaluation of
the drug metabolism will be reported separately but not included in the CTR of this trial. The
study samples will be discarded after completion of the experiments but not later than 5 years
after the final study report has been signed.
5.3.2.3
Urine sampling for pharmacokinetic analysis
A blank urine sample will be collected before administration of trial medication (within 3 h
before drug dosing) and two 0.5 mL aliquots will be retained to check for analytical
interference by concomitant or rescue medication.
All urine voided during the sampling intervals indicated in the Flow Chart 1/2/3/4 will be 
collected in 2 L polyethylene (PE) containers and stored at room temperature. Subjects are 
told to empty their bladders at the end of each sampling interval.
The urine weight/volume for each collection interval will be documented (however, no
correction for the specific gravity of urine is done, i.e. 1 L is defined to be equal to 1 kg).
For details please see lab manual/ISF.

ASSESSMENT OF BIOMARKER(S)
5.4.1
Biochemical and cellular biomarkers
Biomarkers will be assessed to monitor pharmacodynamic drug effects over the course of the 
observation time. Assessment of biomarkers in blood will be done in all subjects.
Direct target engagement of BI 1323495 in blood will be evaluated in Part I of the trial 
 
5.4.1.1
Methods of sample collection
Blood samples will be taken at time points indicated in the Flow Chart 1/2/4.
A maximum of approximately 20 ml blood will be collected per biomarker sampling time-
point per subject for the pre-specified biomarker analyses. This sums up to a total blood 
volume of approximately 60 mL collected for biomarker analyses over the 3 weeks 
observational period.
Detailed instructions for biomarker blood sampling, processing, storage and shipment of the 
different biofluids will be provided in the lab manual/site’s ISF.

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 adequate way allowing for appropriate risk mitigation in 
a clinical trial during the early clinical development phase when only limited information is 
available yet on the IMP. 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 5.3 are established assessments of drug 
exposure. The biomarkers and pharmacodynamic parameters and measurements outlined in 
Sections 5.4 are of exploratory nature.

INVESTIGATIONAL PLAN
6.1
VISIT SCHEDULE
The trial consists of a screening period, an 11 days multiple dose treatment and a Follow-up 
period. The acceptable time windows for visits and trial procedures are given in the Flow 
Chart 1/2/3/4. Exact times of measurements outside the permitted time windows will be 
documented. 
Screening Visit and Day -3 to -1 (or Day -2 to -4 for midazolam dose groups) may be 
combined if feasible. 
Study measurements and assessments scheduled to occur ‘before’ trial medication 
administration on Day 1 and Day 11 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, PK 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, except for V3 (EoS 
Visit), where a deviation of -120 min to + 72 h is acceptable. 
If several activities are scheduled at the same time point in the Flow Chart 1/2/3/4, 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 Flow Chart 1/2/3/4. 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.

lead ECG, as well as an assessment of laboratory values including drug and virological 
screening, and pregnancy testing in females will be performed. 
If V1 takes place within the last three days before first drug administration, or first 
midazolam administration, respectively, and all required assessments are completed before 
V2/Day 1, the visit Day -3 to -1 (resp. Day -4 to -2 in the midazolam groups) and related 
assessments may be skipped.
For information regarding laboratory tests (including drug and virus screening), ECG, vital 
signs, and physical examination, refer to Sections 5.2.1 to 5.2.4.
The subject should be recorded on the enrolment log as screened.
6.2.2
Treatment period
In any case, within the last three days before single dose administration, or midazolam 
administration, as applicable, subjects will visit the site and main eligibility criteria will be 
reviewed and safety lab performed. 
Subjects will be admitted to the site in the evening before first drug administration on Day 1
(Part I: DG 1, DG 2 and DG 7, and Part II), and in the evening before first midazolam 
administration on Day -1 (Part I: DG 3, DG 4 and DG 6), respectively. A subject who is 
eligible for the study will be randomised into the current dose group and receive the first dose
of BI 1323495 or placebo on Day 1. During treatment phase up to Day 10, each subject will 
receive multiple bid doses of BI 1323495 or placebo, or multiple qd doses of BI 1323495 or 
placebo in DG 7, and a last single dose on Day 11.
Trial medication will be taken orally by each subject under direct supervision of the 
investigator or 
designee. 
Study participants will stay at the site under medical surveillance during the treatment phase.
The subjects will then be allowed to leave the trial site after formal assessment and 
confirmation of their fitness by the investigator or 
 designee, and return to further visits as 
indicated in the Flow Chart 1/2/3/4.
For details on time points and procedures for collection of blood and urine samples for PK 
analysis, refer to Flow Chart 1/2/3/4 and Section 5.3.2. 
The safety assessments performed during the treatment period are specified in Section 5.2 of 
this protocol and in the Flow Chart 1/2/3/4.
For details on time points for all other trial procedures, refer to the Flow Chart 1/2/3/4. AEs 
and concomitant therapy will be assessed continuously from screening until the end of trial 
examination.
Safety evaluation between 1st and 2nd cohort of each Dose Group
Between start of the last patient of cohort 1 and start of cohort 2 there will be a time interval 
of at least 7 days. Subjects of cohort 2 will only enter treatment if the following safety-
relevant data from the subjects in cohort 1, who are expected to have reached PK steady state 
 have been evaluated:

Adverse events as recorded at that time

Follow up period and trial completion
For AE assessment, laboratory tests, recording of ECG and vital signs, and physical 
examination during the follow-up period, see Sections 5.2.1 to 5.2.6.
Subjects who discontinue treatment before the end of the planned treatment period should 
undergo the End of Study 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. All visit procedures of the Visits during Follow-up period Day 12 to Day 16
and at Visit 3 (Day 18 to 21) (EoS) Visit have to be completed as indicated in the Flow Chart 
1/2/3/4.

STATISTICAL METHODS AND DETERMINATION OF
SAMPLE SIZE
7.1
NULL AND ALTERNATIVE HYPOTHESES
Safety and tolerability of 6 different dose groups of BI 1323495 in Part I and two different 
dose groups in Part II 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 be interpreted in the perspective of the 
exploratory character of the study, i.e. confidence intervals are considered as interval 
estimates for effects.
7.2
PLANNED ANALYSES
7.2.1
General considerations
Analysis sets
Statistical analyses will be based on the following analysis sets:

Treated set (TS): The treated set includes all subjects who were randomised 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.
Further PK and PD sets for different strata may be defined in TSAP, if needed. 
Adherence to the protocol will be assessed by the trial team. Important protocol deviation 
(iPD) categories will be specified in the Integrated Quality and Risk Management Plan 
(IQRMP). IPDs will be identified no later than in the Blinded Report Planning Meeting, and 
the iPD categories will be updated as needed.
Pharmacokinetics
The pharmacokinetic parameters listed in Section 2.1 and 2.2 for drug BI 1323495 or 
midazolam and 1-OH midazolam will be calculated according to the relevant BI internal 
procedures.
Plasma and urine concentration data and parameters of a subject will be included in the 
statistical pharmacokinetic (PK) analyses if they are not flagged for exclusion due to a 
protocol deviation relevant to the evaluation of PK (to be decided no later than in the Blinded

Report Planning Meeting) or due to PK non-evaluability (as revealed during data analysis, 
based on the criteria specified below). Exclusion of a subject’s data will be documented in the 
CTR.
Relevant protocol deviation 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 and urine 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/urine 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). 
7.2.2
Primary endpoint analyses
The primary endpoint as specified in Section 2.1.2 will be derived according to BI standards. 
Inferential statistics is not planned here. The analysis will be based on the treated set (TS) and 
will be descriptive in nature. For Part I only, this analysis will be repeated for all categories 
of stratification factor (gender). 
7.2.3
Secondary endpoint analyses
Primary analyses
The secondary endpoints (refer to Section 2.1.3) will be analysed descriptively. Analyses will 
be performed for the parent drug.
Further exploratory analyses

7.2.5
Safety analyses
All treated subjects will be included in the safety analysis. In general, safety analyses will be 
descriptive in nature and will be based on BI standards. No hypothesis testing is planned.
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 
Blinded 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 (see Section 4.1) based on the actual treatment at the planned time of the 
measurement or on the recorded time of AE onset (concept of treatment-emergent AEs). 
Therefore, measurements planned or AEs recorded prior to first intake of trial medication will 
be assigned to the screening period, those between the first trial medication intake and end of 
REP (see 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). 
Frequency, severity, and causal relationship of adverse events will be tabulated by system 
organ class and preferred term after coding according to the current version of the Medical 
Dictionary for Drug Regulatory Activities (MedDRA) at database lock.
Laboratory data will be analysed both quantitatively as well as qualitatively. The latter will 
be done via comparison of laboratory data to their reference ranges. Values outside the 
reference range as well as values defined as clinically relevant will be summarised. Treatment 
groups will be compared descriptively with regard to distribution parameters as well as with

regard to frequency and percentage of subjects with abnormal values or clinically relevant

HANDLING OF MISSING DATA
7.3.1
Safety
It is not planned to impute missing values for safety parameters.
7.3.2
Plasma/urine drug concentration - time profiles
Handling of missing PK data will be performed according to the relevant BI internal 
procedure. Drug concentration data identified with NOS (no sample available), NOR (no 
valid result), NOA (not analysed), BLQ (below the lower limit of quantification), or NOP (no 
peak detectable) will be displayed as such and not replaced by zero at any time point (this 
rule applies also to the lag phase, including the predose values).

7.3.3
Pharmacokinetics
Handling of missing PK data will be performed according to the relevant BI internal 
procedure.
PK parameters that cannot be reasonably calculated based on the available drug 
concentration-time data will not be imputed.
7.4
RANDOMISATION
BI will arrange for the randomisation and the packaging and labelling of trial medication. The 
randomisation list will be generated using a validated system, which involves a pseudo-
random number generator so that the resulting treatment will be both reproducible and non-
predictable. The block size will be documented in the Clinical Trial Report. Access to the 
codes will be controlled and documented.
The randomisation list will contain additional blocks to allow for subject replacement (refer 
to 3.3.5).
7.5
DETERMINATION OF SAMPLE SIZE
It is planned to include a total of 88 subjects in this trial. The planned sample size is not based 
on a power calculation. The size of 8-12 subjects per dose group is commonly used in 
multiple-rising dose studies of the present type and is in general considered as sufficient for 
the exploratory evaluation of multiple dose safety and pharmacokinetics. The sample size in 
the PM dose groups of 8 subjects (6 on active treatment and 2 on placebo) is lower than in the 
EM dose groups (12, of which 9 on active treatment and 3 on placebo), as an additional 
objective in the EM dose groups is the assessment of potential gender effects on exposures 
with BI 1323495. It is assumed that stratification by gender in each EM dose group leads to 8 
trial subjects being males (6 on active treatment and 2 on placebo), whereas 4 will be females 
(3 on active treatment and 1 on placebo). Hence, the sample size of the PM dose groups, that 
do not look at potential gender effects, is equivalent to the sample size of the larger male 
subpopulation in the EM dose groups.

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. See Section 4.1.5.2 for rules 
about emergency code breaks. For drug accountability, refer to Section 4.1.8.
8.3.1
Source documents
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. 
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 trial indication and concomitant diseases, if applicable)

Medication history

ECG results (original or copies of printouts)

Adverse events and outcome events (onset date (mandatory), and end date (if available))


Serious adverse events (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.
8.3.2
Direct access to source data and documents
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 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.
8.3.3
Storage period of records
Trial site(s):
The trial site(s) 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.
8.4
EXPEDITED REPORTING OF ADVERSE EVENTS
BI is responsible to fulfil their legal and regulatory reporting obligation in accordance with
regulatory requirements. 
8.5
STATEMENT OF CONFIDENTIALITY AND SUBJECT PRIVACY
Individual subject data obtained as a result of this trial is considered confidential and 
disclosure to third parties is prohibited with the exceptions noted in Section 8.7. 
Data protection and data security measures are implemented for the collection, storage and 
processing of subject data in accordance with the principles 6 and 12 of the WHO GCP 
handbook.
Personalised treatment data may be given to the subject’s personal physician or to other 
appropriate medical personnel responsible for the subject’s welfare. Data generated at the site

effect on BI 1323495 exposure upon co-administration of 
a strong CYP3A4 inhibitor, with the consequence that
concomitant treatment only with strong (not all)
CYP3A4/P-gp inhibitors is to be avoided, no safety issues 
reported.
Rationale for change
New information available
Section to be changed
1.4.3, 4.2.2.3
Description of change
Added instruction on adequate, non-hormonal 
contraception methods
Rationale for change
Inclusion of WOCBP is only justifiable with adequate 
highly effective contraception. Due to potential CYP3A4 
induction by BI 1323495, hormonal contraception might 
be less effective, thus instruction on acceptable highly 
effective contraception methods is provided.
Section to be changed
3.1.1
Description of change
Added details on how the population PK model is updated 
to predict exposure in the next dose group.
Rationale for change
Clarification of procedures for exposure predictions for 
subsequent dose groups

additional risks to trial participants in the course of this 
pandemic, the trial was temporarily put on hold after 
completion of Part I DG 2 and prior to the start of Part I 
DG 3. Potential additional risks for study participants with 
regard to COVID-19 have been evaluated and risk 
management measures implemented within the sections
cited above.

Previous Dose Groups are named Part I or EM Dose 
Groups, new Dose Groups are named Part II or PM Dose 
Groups. In the whole document the allocation of dose 
groups to either Part I or Part II of the trial was specified.

Global Amendment due to urgent safety reasons
Global Amendment
Comment: This non-substantial amendment is implemented to add an intermediate dose 
group following provisions as given in earlier versions of the protocol:
“Additional subjects may be entered to allow testing of an additional (intermediate) dose 
based on preliminary PK data). The approved highest dose for each of the two trial parts will 
not be exceeded. Thus, the actual number of subjects entered may exceed 76, but will not 
exceed 96 subjects. Such a change would be implemented as a non-substantial CTP 
amendment.”
