Duration of treatment
One day (single dose) for each treatment
Statistical methods
Relative bioavailability will be estimated by the ratios of the geometric means 
(test/reference) for the primary and secondary endpoints. Additionally, their two-
sided 90% confidence intervals (CIs) will be provided. This method corresponds to 
the two one-sided t-test procedure, each at a 5% significance level. Since the main 
focus is on estimation and not testing, a formal hypothesis test and associated 
acceptance range is not specified. The statistical model will be an analysis of 
variance (ANOVA) on the logarithmic scale including effects for sequence, subjects 
nested within sequences, period and treatment. CIs will be calculated based on the 
residual error from the ANOVA.
Descriptive statistics will be calculated for all endpoints.

Clinical experience with BI 1323495
At the time of CTA submission of this trial, the first in man study 1405-0001 had been 
initiated. This partially randomized within dose groups, placebo-controlled trial investigates 
the safety, tolerability, pharmacokinetics and pharmacodynamics of single rising oral doses 
of BI 1323495 as tablet formulation. As of 14 November 2018, the clinical part has been
completed as planned. A total of 63 subjects were randomized to treatment with either

placebo (N=15) or single ascending doses of 
 
BI 1323495 (N=6 per dose). An overview on preliminary results of this 
trial is given in the following.
Treatments with BI 1323495 tablets or placebo were safe and well tolerated at all doses 
investigated. Overall, 16 out of 48 subjects treated with BI 1323495 (33.3%) and 2 out of 15
subjects treated with placebo (13.3%) were reported with at least 1 AE following drug 
administration. No dose dependency was observed for the different BI 1323495 treatment 
groups. The most frequently reported AE was headache, observed in 6 subjects (12.5%) 
dosed with BI 1323495 and 2 subjects (13.3%) on placebo. The incidence of headache
appeared similar between the different BI 1323495 dose groups and placebo.
AEs were generally of short duration and mild in intensity apart from 1 case of moderate 
headache 
moderate common cold reported by 
one subject 
, and 1 case of moderate rhinitis 
 
. Severe or serious AEs were not reported. All AEs were followed-up until 
resolved.
A summary of AEs reported following study drug treatment is shown in Table 1.2.4.1: 1.

No adverse events based on ECG or vital signs were reported. Also no trends of changes 
were observed.
Noteworthy: Subject 
(
 BI 1323495) presented with an increase in pulse rate 
compared to baseline from 5h to 12h postdose, i.e. after the end of bed rest period. Systolic 
blood pressure showed also a trend to higher values in the same period. This is explained by 
increased physical activity and not considered as clinically relevant. Furthermore, subject 
 
who was randomised to placebo, had single ECGs with absolute QT of 502 ms (2/3 ECGs at 
2h p.a.) and 500 ms (1/3 ECGs at 3h p.a.). Change from baseline was below 60 ms and QTc 
below 430 ms.
The clinical laboratory evaluation included the analysis of haematology, coagulation, 
enzymes, substrates, electrolytes, urinalysis, and inflammatory parameters. In general, values 
of measured laboratory parameters were within or only slightly outside the respective 
reference ranges. There were no hints for relevant changes over time and no relevant 
differences between the treatment groups (including placebo) in any of the safety laboratory 
parameters measured.
Noteworthy: Subject 
 (
 BI 1323495) presented with mild elevation of ALT and 
GLDH. Highest value for ALT was seen 4 days after drug administration (96 U/L, ULN=50 
U/L); follow-up measurements were done until returned to almost normalized value of 51 
U/L at 16 days postdose. Highest value for GLDH was already seen at 4h p.a. (11 U/L, 
ULN= 7.0 U/L). GLDH value returned to normal range 5 days after drug administration.
Both laboratory findings are reported as adverse events of mild intensity and potentially 
related to the administration of BI 1323495.
Pharmacokinetic results:
Plasma samples were taken up to 96 h after drug administration. Preliminary PK data analysis 
for BI 1323495 used planned vs actual sampling times for all dose groups. Bioanalytical data 
of BI 1323495 and PK calculation is preliminary and subject to change.

1.2.5
Residual Effect Period
The Residual Effect Period (REP) of BI 1323495, i.e., the time interval when measurable 
drug levels or PD effects are still likely to be present after administration, is not yet known. 
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.
1.3
RATIONALE FOR PERFORMING THE TRIAL
In the ongoing single rising dose study, only pharmacokinetic data under fasted conditions 
are investigated for BI 1323495. The planned food interaction study will generate 
pharmacokinetic information under fed conditions to support the future development in 
patients.
1.4
BENEFIT - RISK ASSESSMENT
Participation in this clinical trial is without any (therapeutic) benefit for healthy subjects. 
Their participation, however, is of major importance for the development of a new orally 
available drug, which might improve the therapy in patients with COPD and emphysema. 
The subjects are exposed to the risks of the study procedures and the risks related to the 
exposure to the trial medication.
Procedure-related risks
The use of an indwelling venous catheter or venepuncture for e.g. blood sampling may result 
in mild bruising, and in rare cases, in transient inflammation of the wall of the vein, or nerve 
injury, potentially resulting in paraesthesia, reduced sensibility, and/or pain for an indefinite 
period.
The total volume of blood withdrawn per subject during the entire study will not exceed the 
volume of a normal blood donation (500 mL). No health-related risk to healthy subjects is 
expected from withdrawal of this volume of blood.

In this food effect trial, subjects will receive two single doses of 
 once under fasted 
and once under fed conditions. Administration of BI 1323495 under fed conditions may cause 
an increase of plasma concentrations of BI 1323495. However, based on modelling data for 
the tablet formulation used in the SRD trial and this food effect trial only a minimal food 
effect is expected for a dose of
resulting in plasma concentrations below those 
exposures seen in the SRD trial following doses of 
and above.

DESCRIPTION OF DESIGN AND TRIAL POPULATION
3.1
OVERALL TRIAL DESIGN AND PLAN
The study will be performed as a randomised, open-label, two-way crossover trial in healthy 
male subjects in order to compare the test treatment (T) to the reference treatment (R). The 
treatments will be two single oral doses of 
 BI 1323495 separated by a washout period 
 between the treatments:
Treatment T:
 tablets of BI 1323495, fed
Treatment R:
 tablets of BI 1323495, fasted
The subjects will be randomly allocated to the 2 treatment sequences (T-R or R-T). For 
details, refer to Section 4.1.
An overview of all relevant trial activities is provided in the Flow Chart. For visit schedule 
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 GROUPS
For relative bioavailability trials, the crossover design is preferred because of its efficiency: 
since each subject serves as his own control, the comparison between treatments is based on 
an intra-subject comparison, thus removing inter-subject variability from the comparison 
between treatments (R94-1529).
The open-label treatment is not expected to bias results, since the study endpoints are derived 
from measurement of plasma concentrations of the analyte, which are provided by a 
bioanalytical laboratory that is blinded to treatment allocation.
3.3
SELECTION OF TRIAL POPULATION
It is planned that 12 healthy male subjects will enter the study. They will be recruited from 
the volunteers' pool of the trial site.
Only male subjects will be included in the study because no data on reproductive toxicology 
are available at this time.
A log of all subjects enrolled into the trial (i.e. who have signed informed consent) will be 
maintained in the ISF irrespective of whether they have been treated with investigational drug 
or not.
3.3.1
Main diagnosis for trial entry
The study will be performed in healthy subjects.
3.3.2
Inclusion criteria
Subjects will only be included in the trial if they meet the following criteria:

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, a complete end of trial examination will be performed, if possible, and the 
information will be recorded in the CRF. If the discontinuation occurs before the end of the 
REP (see Section 1.2.5), the discontinued subject should if possible be questioned for AEs 
and concomitant therapies at or after the end of the REP in order to ensure collection of AEs 
and concomitant therapies throughout the REP, if not contrary to any consent withdrawal of 
the subject.

3.3.4.1
Discontinuation of trial treatment
An individual subject will discontinue trial treatment if:
1. The subject wants to discontinue trial treatment, without the need to justify the decision
2. 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.
3. The subject needs to take concomitant medication that interferes with the investigational 
medicinal product or other trial treatment
4. The subject can no longer receive trial treatment for medical reasons (such as surgery, 
adverse events [AEs], or diseases)
5. The subject has an elevation of AST and/or ALT ≥3-fold upper limit of normal (ULN)
and an elevation of total bilirubin ≥2-fold ULN (measured in the same blood sample) 
and/or needs to be followed up according to the DILI checklist provided in the ISF.
6. The subject experiences a drug-related serious adverse event or drug-related severe 
adverse event. AEs will be considered as drug-related unless clearly unrelated (e.g. events 
prior to administration of study drug), see Section 5.1.5.1.6.
In addition to these criteria, the investigator may discontinue subjects at any time based on 
his or her clinical judgment.
Even if the trial treatment is discontinued, the subject remains in the trial and, given his/her 
agreement, will undergo the procedures for early treatment discontinuation and follow up as 
outlined in the Flow Chart 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. If a subject wants to withdraw consent, the investigator should be
involved in the discussion with the subject and explain the difference between trial treatment 
discontinuation and withdrawal of consent to trial participation, as well as explain the options 
for continued follow up after trial treatment discontinuation, please see Section 3.3.4.1 above
3.3.4.3
Discontinuation of the trial by the sponsor
Boehringer Ingelheim reserves the right to discontinue the trial at any time for any of the 
following reasons:
1. Failure to meet expected enrolment goals overall or at a particular trial site
2. New toxicological findings, serious adverse events, or any safety information invalidating
the earlier positive benefit-risk-assessment. More specifically, the trial will be terminated 
or suspended if more than 50% of the subjects have drug-related and clinically relevant 
adverse events of moderate or severe intensity, if more than two subjects have drug-
related non-serious adverse events of severe intensity or if at least 1 drug-related serious 
adverse event is reported. AEs will be considered as drug-related unless clearly unrelated 
(e.g., events prior to administration of study drug), see Section 5.1.5.1.6. 
Any further dosing is only possible after an analysis and evaluation of the harm, review of

Based on the experience gained during trial 1405-0001, a lower dose of BI 1323495 may be 
tested in this trial. If the lower dose is selected for safety reasons, this will be implemented 
via substantial amendment only.
4.1.3
Method of assigning subjects to treatment groups
The randomisation list will be provided to the trial site in advance.
Subjects will be allocated to treatment sequences prior to the first administration of trial 
medication in the morning of Day 1 (Visit 2). For this purpose, numbers of the randomisation 
list will be allocated to the subjects by drawing lots. Subjects are then assigned to a treatment 
sequence according to the randomisation list.
Once a subject number has been assigned, it cannot be reassigned to any other subject.
All subjects may be treated in one cohort, i.e. all subjects may receive treatment on the same 
calendar day. In case this is not feasible (e.g., due to logistical or recruitment reasons), the 
group may be split into several cohorts as required. Treatment of all subjects on the same 
calendar day is acceptable (for safety margin to exposure reached in SRD trial 1405-0001 and
for discussion of study-associated risks and safety measures, see Section 1.4).
The randomisation procedure is described in Section 7.6.
4.1.4
Drug assignment and administration of doses for each subject
This trial is a 2-way crossover study. All subjects will receive the 2 treatments in randomised 
order. The treatments to be evaluated are outlined in Table 4.1.4: 1 below.

In treatment T, a high-fat, high-calorie meal will be served within 30 min before drug 
administration. The subjects must completely consume the meal prior to drug intake. The 
composition of the standard high-fat, high-calorie meal is detailed in Table 4.1.4: 2; this meal 
is in compliance with the FDA guidance ‘Food-Effect Bioavailability and Fed 
Bioequivalence Studies’ (R03-2269). For restrictions with regard to diet, see Section 4.2.2.2.

The total caloric content was supplied approximately as following: 150 kcal as protein, 250 kcal 
as carbohydrate, and 500 to 600 kcal as fat. 
The investigator (or authorised designee) will administer the trial medication as an oral dose 
together with about 240 mL of water to subjects who are in a standing position. For drug 
administration, the so-called four-eye principle (two-person rule) should be applied. For this, 
one authorised employee of the trial site should witness the administration of trial medication, 
and – if applicable – its preparation (e.g. reconstitution), if correct dosage cannot be ensured 
otherwise.
Subjects will be kept under close medical surveillance until 24 h after drug administration. 
During the first 4 h after drug administration, subjects are not allowed to lie down (i.e. no 
declination of the upper body of more than 45 degrees from upright posture).
The treatments will be separated by a wash-out phase of at least 6 days.
4.1.5
Blinding and procedures for unblinding
This Phase I trial will be handled in an open fashion throughout (that is, during the conduct,
including data cleaning and preparation of the analysis). This is considered acceptable 
because the potential for bias seems to be low and does not outweigh practical considerations.
Emergency envelopes will not be provided, because the dose of trial medication is known to 
investigators and subjects.
PK samples will be labelled in such a way that treatment allocation cannot be derived by the 
analytical site.
4.1.6
Packaging, labelling, and re-supply
The investigational medicinal products will be provided by BI. They will be packaged and 
labelled in accordance with local law and the principles of Good Manufacturing Practice. 
For details of packing and the description of the label, refer to the ISF.
The telephone number of the sponsor and the name, address and telephone number of the trial 
site are provided in the subject information form. The EudraCT number is indicated on the 
title page of this protocol as well as on the subject information and informed consent forms. 
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 in accordance with the recommended (labelled) storage conditions. If necessary, a 
temperature log must be maintained to make certain that the drug supplies are stored at the 
correct temperature. If the storage conditions are found to be outside the specified range, the 
local clinical monitor (as provided in the list of contacts) is to be contacted immediately.
4.1.8
Drug accountability
The investigator or designee will receive the investigational drugs delivered from the sponsor
following requirements are fulfilled:

Approval of the clinical 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 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.
The investigator or designee 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 medicinal product and trial subjects. The 
investigator or designee will maintain records that document adequately that the subjects 
were provided the doses specified by the CTP and reconcile all investigational medicinal 
products received from the sponsor. At the time of disposal of remaining trial medication, the 
investigator or designee must verify that no remaining supplies are in the investigator’s 
possession.
All unused medication will be disposed of locally by the trial site upon written authorisation 
of the trial clinical monitor. Receipt, usage and disposal of trial medication must be 
documented on the appropriate forms. Account must be given for any discrepancies.

OTHER TREATMENTS, EMERGENCY  PROCEDURES,
RESTRICTIONS
4.2.1
Other treatments and emergency procedures
There are no special emergency procedures to be followed. No additional treatment is 
planned. However, if adverse events require treatment, the investigator can authorise 
symptomatic therapy. In those cases, subjects will be treated as necessary and, if required, 
kept under supervision at the trial site or transferred to a hospital until all results of medical 
evaluations are acceptable.

Alcoholic beverages, grapefruits, Seville oranges (sour or bitter oranges) and their juices, and 
dietary supplements and products containing St. John's wort (Hypericum perforatum) are not 
permitted from 7 days before the first administration of trial medication until after the last PK 
sample is collected.
Smoking as well as methylxanthine-containing drinks or foods (such as coffee, tea, cola, 
energy drinks, or chocolate) are not allowed during in-house confinement.
Excessive physical activity (such as competitive sport) should be avoided from 7 days before 
the first administration of trial medication until the end of trial examination.
Direct exposure to the sun or exposure to solarium radiation should be avoided during the 
entire study.
4.3
TREATMENT COMPLIANCE
Compliance will be assured by administration of all trial medication in the study centre under 
supervision of the investigating physician or a designee. The measured plasma concentrations 
of trial medication will provide additional confirmation of compliance.
Subjects who are non-compliant (for instance, who do not appear for scheduled visits or 
violate trial restrictions) may be removed from the trial and the CRF will be completed 
accordingly (for further procedures, please see Section 3.3.4.1).

ASSESSMENTS
5.1
ASSESSMENT OF SAFETY
5.1.1
Physical examination
At screening, the medical examination will include demographics, height and body weight, 
smoking and alcohol history (results of smoking and alcohol history not mandatory to be 
entered into CRF or to be reported), relevant medical history and concomitant therapy, 
review of inclusion and exclusion criteria, review of vital signs (BP, PR), 12-lead ECG, 
laboratory tests, and a physical examination. At the end of trial examination, it will include 
review of vital signs, 12-lead ECG, laboratory tests, and a physical examination.
5.1.2
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.
5.1.3
Safety laboratory parameters
For the assessment of laboratory parameters, blood and urine samples will be collected by the 
trial site at the times indicated in the Flow Chart after the subjects have fasted for at least 
10 h. For retests, at the discretion of the investigator or designee, overnight fasting is not 
required.
The parameters that will be determined are listed in Tables 5.1.3: 1 and 5.1.3: 2. Reference 
ranges will be provided in the ISF, Section 10. 
Manual differential white blood cell count or urine sediment examinations will only be 
performed if there is an abnormality in the automatic blood cell count or in the urinalysis, 
respectively.

may be repeated at any time during the study at the discretion of an investigator or designee. 
The results will not be included in the CTR.
The laboratory tests listed in Tables 5.1.3: 1 and 5.1.3: 2 will be performed 
 
 with the exception of 
drug screening tests. These tests will be performed at the trial site using M-10/14-PDT test or 
a comparable test system.
Laboratory data will be transmitted electronically from the laboratory to the trial site.
5.1.4
Electrocardiogram
Twelve-lead 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 times provided in the Flow Chart. 
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 assessment will always precede all other study procedures scheduled 
for the same time to avoid compromising ECG quality. 
All ECGs will be stored electronically on the Muse CV Cardiology System (GE Medical 
Systems, Freiburg, Germany). Electrode placement will be performed according to the 
method of Wilson, Goldberger and Einthoven modified by Mason and Likar (hips and 
shoulders instead of ankles and wrists).
All locally printed ECGs will be evaluated by the investigator or a designee. Abnormal 
findings will be reported as AEs (during the trial) or baseline conditions (at screening) if 
assessed to be clinically relevant by the investigator. Any ECG abnormalities will be 
carefully monitored and, if necessary, the subject will be removed from the trial and will 
receive the appropriate medical treatment. 
ECGs may be repeated for quality reasons (for instance, due to alternating current artefacts, 
muscle movements, or electrode dislocation) and the repeated ECG will be used for analysis. 
Additional (unscheduled) ECGs may be collected by the investigator for safety reasons. 
5.1.5
Assessment of adverse events
5.1.5.1
Definitions of adverse events
Adverse event
5.1.5.1.1
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.

001-MCS-40-106-RD-13 (6.0) / Saved on: 13 Jun 2018
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.
Serious adverse event
5.1.5.1.2
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’
5.1.5.1.3
Cancers of new histology and exacerbations of existing cancer must be classified as a serious 
event regardless of the time since discontinuation of the trial medication and must be reported 
as described in 5.1.5.2, 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
5.1.5.1.4
The term adverse events of special interest (AESI) relates to any specific AE that has been 
identified at the project level as being of particular concern for prospective safety monitoring 
and safety assessment within this trial, e.g. the potential for AEs based on knowledge from 
other compounds in the same class. AESIs need to be reported to the sponsor’s 
Pharmacovigilance Department within the same timeframe that applies to SAEs, please see 
Section 5.1.5.2.2.
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 transaminase) and/or ALT (alanine 
transaminase) ≥3-fold ULN combined with an elevation of total bilirubin 
≥2-fold ULN measured in the same blood sample, or
o
Aminotransferase (ALT, and/or AST) elevations ≥10 fold ULN
These lab findings constitute a hepatic injury alert and the subjects showing these lab
abnormalities need to be followed up according to the ‘DILI checklist’ provided in the 
ISF. In case of clinical symptoms of hepatic injury (icterus, unexplained 
encephalopathy, unexplained coagulopathy, right upper quadrant abdominal pain, 
etc.) without lab results (ALT, AST, total bilirubin) available, the Investigator should 
make sure that these parameters are analysed, if necessary in an unscheduled blood 
test. Should the results meet the criteria of hepatic injury alert, the procedures 
described in the DILI checklist should be followed.
Intensity (severity) of AEs
5.1.5.1.5
The intensity (severity) of the AE should be judged based on the following:
Mild:
Awareness of sign(s) or symptom(s) that is/are easily tolerated
Moderate:
Sufficient discomfort to cause interference with usual activity
Severe:
Incapacitating or causing inability to work or to perform usual activities
Causal relationship of AEs
5.1.5.1.6
Medical judgment should be used to determine the relationship, considering all relevant 
factors, including pattern of reaction, temporal relationship, de-challenge or re-challenge, 
confounding factors such as concomitant medication, concomitant diseases and relevant 
history.
Arguments that may suggest that there is a reasonable possibility of a causal relationship 
could be:

The event is consistent with the known pharmacology of the drug 

The event is known to be caused by or attributed to the drug class

A plausible time to onset of the event relative to the time of drug exposure


Evidence that the event is reproducible when the drug is re-introduced

No medically sound alternative aetiologies that could explain the event (e.g. pre-
existing or concomitant diseases, or co-medications)

The event is typically drug-related and infrequent in the general population not 
exposed to drugs (e.g. Stevens-Johnson syndrome)

An indication of dose-response (i.e. greater effect size if the dose is increased, smaller 
effect size if dose is reduced)
Arguments that may suggest that there is no reasonable possibility of a causal relationship 
could be:

No plausible time to onset of the event relative to the time of drug exposure is evident 
(e.g. pre-treatment cases, diagnosis of cancer or chronic disease within days / weeks 
of drug administration; an allergic reaction weeks after discontinuation of the drug 
concerned)

Continuation of the event despite the withdrawal of the medication, taking into 
account the pharmacological properties of the compound (e.g. after 5 half-lives). Of 
note, this criterion may not be applicable to events whose time course is prolonged 
despite removing the original trigger

Additional arguments amongst those stated before, like alternative explanation (e.g. 
situations where other drugs or underlying diseases appear to provide a more likely 
explanation for the observed event than the drug concerned)

Disappearance of the event even though the trial drug treatment continues or remains 
unchanged
5.1.5.2
Adverse event collection and reporting
AE collection
5.1.5.2.1
Upon enrolment into a trial, the subject’s baseline condition is assessed (for instance, by 
documentation of medical history/concomitant diagnoses), and relevant changes from 
baseline are noted subsequently. 
Subjects will be required to report spontaneously any AEs as well as the time of onset, end
time, and intensity of these events. In addition, each subject will be regularly assessed by the 
medical staff throughout the clinical trial and whenever the investigator deems necessary. As 
a minimum, subjects will be questioned for AEs (and concomitant therapies) at the time 
points indicated in the Flow Chart. Assessment will be made using non-specific questions 
such as ‘How do you feel?’. Specific questions will be asked wherever necessary in order to 
more precisely describe an AE.
A carefully written record of all AEs shall be kept by the investigator in charge of the trial. 
Records of AEs shall include data on the time of onset, end time, intensity of the event, and 
any treatment or action required for the event and its outcome.
The following must be collected and documented on the appropriate CRF(s) by the 
investigator:

From signing the informed consent onwards until an individual subject’s end of trial:

o
All AEs (serious and non-serious) and all AESIs 
o
The only exception to this rule are AEs (serious and non-serious) and AESIs 
in Phase I trials in healthy volunteers, when subjects discontinue from the trial 
due to screening failures prior to administration of any trial medication. In 
these cases, the subjects’ data must be collected at trial site but will not be 
entered in the CRF or trial database and will not be reported in the CTR.

After the individual subject’s end of trial: 
o
The investigator does not need to actively monitor the subject for AEs but 
should only report any occurrence of cancer and related SAEs and related 
AESIs of which the investigator may become aware of by any means of 
communication, e.g. phone call. Those AEs should, however, not be reported 
in the CRF.
AE reporting to the sponsor and timelines
5.1.5.2.2
The Investigator must report SAEs, AESIs, and non-serious AEs which are relevant for the 
reported SAE or AESI, on the BI SAE form via fax immediately (within 24 hours) to the 
sponsor’s unique entry point (country specific contact details will be provided in the ISF). 
The same timeline applies if follow-up information becomes available. In specific occasions 
the Investigator could inform the sponsor upfront via telephone. This does not replace the 
requirement to complete and fax the BI SAE form. 
With receipt of any further information to these events, a follow-up SAE form has to be 
provided. For follow-up information, the same rules and timeline apply as for initial 
information.
Information required
5.1.5.2.3
All (S)AEs, including those persisting after the individual subject’s end of trial, must be 
followed up until they have resolved, have been sufficiently assessed as ‘chronic’ or ‘stable’, 
or no further information can be obtained.
Pregnancy
5.1.5.2.4
Once the male subject has been enrolled in the clinical trial and has taken trial medication, 
and if a partner of the male trial participant becomes pregnant, the investigator must report 
any drug exposure during pregnancy in a partner of the male trial participant immediately 
(within 24 hours) by means of Part A of the Pregnancy Monitoring Form to the sponsor’s 
unique entry point, after a written consent of the pregnant partner.
The outcome of the pregnancy associated with the drug exposure during pregnancy must be 
followed up and reported to the sponsor’s unique entry point on the Pregnancy Monitoring 
Form for Clinical Trials (Part B).
The ISF will contain the Pregnancy Monitoring Form for Clinical Trials (Part A and Part B) 
as well as non-trial specific information and consent for the pregnant partner.
As pregnancy itself is not to be reported as an AE, in the absence of an accompanying SAE 
and/or AESI, only the Pregnancy Monitoring Form for Clinical Trials and not the SAE form

DRUG CONCENTRATION MEASUREMENTS AND 
PHARMACOKINETICS
5.2.1
Assessment of pharmacokinetics
For the assessment of pharmacokinetics, blood samples will be collected at the time points 
indicated in the Flow Chart. The actual sampling times will be recorded and used for 
determination of pharmacokinetic parameters. 
5.2.2
Methods of sample collection
5.2.2.1
Blood sampling for pharmacokinetic analysis
For quantification of BI 1323495 concentrations in plasma, 2.7 mL of blood will be drawn 
from an antecubital or forearm vein into a K2-EDTA (dipotassium ethylenediaminetetraacetic 
acid)-anticoagulant blood drawing tube at the times indicated in the Flow Chart. Blood will 
be withdrawn by means of either an indwelling venous catheter or by venepuncture with a 
metal needle.
The EDTA-anticoagulated blood samples will be centrifuged for approximately 10 min at 
approximately 2000 x g to 4000 x g and at 4 to 8 °C. Two plasma aliquots will be obtained 
and stored in polypropylene tubes. The first aliquot should contain at least 0.5 mL of plasma. 
The process from blood collection until transfer of plasma aliquots into the freezer should be
completed within 60 min, with interim storage of blood samples at room temperature. The 
time each aliquot was placed in the freezer will be documented. Until transfer on dry ice to 
the analytical laboratory, the aliquots will be stored upright at approximately -20°C or below 
at the trial site. The second aliquot will be transferred to the analytical laboratory after the 
bioanalyst has acknowledged safe arrival of the first aliquot. At the analytical laboratory, the 
plasma samples will be stored at approximately -20°C or below until analysis. 
At a minimum, the sample tube labels should list BI trial number, subject number, visit, and 
planned sampling time. 
After completion of the trial, the plasma samples may be used for further methodological 
investigations (e.g. for stability testing or assessment of metabolites. However, only data 
related to the analyte and/or its metabolite(s) including anti-drug antibodies (if applicable) 
will be generated by these additional investigations. The study samples will be discarded after 
completion of the additional investigations but not later than 5 years after the CTR is 
archived.
5.2.3
Analytical determinations
BI 1323495 concentrations in plasma will be determined by a validated LC-MS/MS (liquid 
chromatography tandem mass spectrometry) assay. All details of the analytical method will 
be available prior to the start of sample analysis.

APPROPRIATENESS OF MEASUREMENTS
All measurements performed during this trial are standard measurements and will be 
performed in order to monitor subjects’ safety and to determine pharmacokinetic parameters 
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 5.3 are 
generally used assessments of drug exposure.

INVESTIGATIONAL PLAN
6.1
VISIT SCHEDULE
Exact times of measurements outside the permitted time windows will be documented. The 
acceptable time windows for screening, for measurements and assessments scheduled to 
occur ‘before’ trial medication administration on Day 1, and the end of trial examination are 
provided in the Flow Chart.
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 of ±120 min is acceptable.
If scheduled in the Flow Chart at the same time as a meal, blood sampling, vital signs, and 
12-lead ECG recordings have to be done first. Furthermore, if several measurements
including venepuncture are scheduled for the same time, venepuncture should be the last of 
the measurements due to its inconvenience to the subject and possible influence on 
physiological parameters.
For planned blood 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 
the determination of pharmacokinetic parameters.
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.

STATISTICAL METHODS AND DETERMINATION OF
SAMPLE SIZE
7.1
STATISTICAL DESIGN – MODEL
The main objective of this trial is to investigate the relative bioavailability of 
 
BI 1323495 administered as tablet formulation in the fed state (Test, T) compared to 
 
 BI 1323495 administered as tablet formulation in the fasted state (Reference, R) on the 
basis of the primary and secondary pharmacokinetic endpoints, as listed in Section 2.1.2 and 
2.1.3. The trial is designed to allow intra-subject comparisons and will be evaluated 
statistically by use of a linear model for logarithmically transformed PK endpoints. 
A further objective is to evaluate and compare further pharmacokinetic parameters between 
the treatments. These pharmacokinetic parameters will be assessed by descriptive statistics.
The assessment of safety and tolerability is a further objective of this trial, and will be 
evaluated by descriptive statistics for the parameters specified in Section 2.2.2.2.
7.2
NULL AND ALTERNATIVE HYPOTHESES
The relative bioavailability of BI 1323495 under fed and fasted conditions will be estimated 
by the ratios of the geometric means (test/reference), and their corresponding 2-sided 90% 
confidence intervals (CIs) will be provided. This method corresponds to the two one-sided t-
test procedure, each at the 5% significance level. Since the main focus is on estimation and

PLANNED ANALYSES
Analysis sets
Statistical analyses will be based on the following analysis sets:

Treated set (TS): The treated set includes all subjects who were randomized and 
treated with at least one dose of study drug. The 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 defined as primary or 
secondary and was not excluded due to a protocol violation relevant to the evaluation
of PK or due to PK non-evaluability (as specified in the following subsection 
‘Pharmacokinetics’). Thus, a subject will be included in the PKS, even if he/she 
contributes only one PK parameter value for one period to the statistical assessment.
Descriptive and model based analyses of PK parameters will be based on the PKS.
Adherence to the protocol will be assessed by the trial team. Important protocol violation 
(IPV) categories will be suggested in the TSAP, IPVs will be identified no later than in the 
Report Planning Meeting, and the IPV categories will be updated as needed.

Pharmacokinetics
The pharmacokinetic parameters listed in Section 2.1 for BI 1323495 will be calculated 
according to the relevant Standard Operating Procedure (SOP) of the Sponsor 
. 
Plasma concentration data and parameters of a subject will be included in the statistical 
pharmacokinetic (PK) analyses if they are not flagged for exclusion due to a protocol 
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)

A predose concentration is >5% Cmax value of that subject

Missing samples/concentration data at important phases of PK disposition curve
Plasma concentration data and parameters of a subject which is flagged for exclusion will be
reported with its individual values but will not be included in the statistical analyses. 
Descriptive and inferential statistics of PK parameters will be based on the PKS.
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). 
7.3.1
Primary endpoint analyses
Primary analyses
The statistical model used for the analysis of the primary endpoints will be an analysis of 
variance (ANOVA) model on the logarithmic scale. That is, the PK endpoints will be log-
transformed (natural logarithm) prior to fitting the ANOVA model. This model will include 
effects accounting for the following sources of variation: sequence, subjects within 
sequences, period and treatment. The effect 'subjects within sequences' will be considered as 
random, whereas the other effects will be considered as fixed. The model is described by the 
following equation:
yijkm = + i + sim + j + k + eijkm, where
yijkm = logarithm of response measured on subject m in sequence i receiving treatment

variables.
Point estimates for the ratios of the geometric means (test/reference) for the primary 
endpoints (see Section 2.1) and their two-sided 90% confidence intervals (CIs) will be 
provided.
For each endpoint, the difference between the expected means for log(T)-log(R) will be 
estimated by the difference in the corresponding adjusted means (Least Squares Means).
Additionally their two-sided 90% confidence intervals will be calculated based on the 
residual error from the ANOVA and quantiles from the t-distribution. These quantities will 
then be back-transformed to the original scale to provide the point estimate and 90% CIs for 
each endpoint.
Further exploratory analyses
The same statistical model as stated above will be repeated for the primary endpoints but with 
all sources of variation (‘sequence’, ‘subjects within sequences’, ‘period’, ‘treatment’) 
considered as fixed effects.
In addition to the model based approach all parameters will be calculated and analysed 
descriptively.
7.3.2
Secondary endpoint analyses
The secondary endpoints (refer to Section 2.1.3) will be calculated according to the BI SOP 
‘Standards and processes for analyses performed within Clinical Pharmacokinetics/ 
Pharmacodynamics’ 
 and will be assessed statistically using the same 
methods as described for the primary endpoints.

7.3.4
Safety analyses
Safety will be analysed based on the assessments described in Section 2.2.2.2. All treated 
subjects (TS, refer to Section 7.3) will be included in the safety analysis. Safety analyses will 
be descriptive in nature and 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 
Report Planning Meeting).
Treatments will be compared in a descriptive way. Tabulations of frequencies/proportions 
will be used to evaluate categorical (qualitative) data, and tabulations of descriptive statistics 
will be used to analyse continuous (quantitative) data.
Measurements (such as ECG, vital signs, or laboratory parameters) or AEs will be assigned to 
treatments (see Section 4.1) based on the actual treatment at the planned time of the 
measurement or on the recorded time of AE onset (concept of treatment emergent AEs).
Therefore, measurements planned or AEs recorded prior to first intake of trial medication will 
be assigned to the screening period, those between first trial medication intake and end of 
trial termination date will be assigned to the treatment period. 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 final database lock will be 
reported to Pharmacovigilance only and will not be captured in the trial database.
Additionally, further treatment intervals (analysing treatments) may be defined in the TSAP 
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 follow-up 
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 5.2.5.1), and 
other significant AEs (according to ICH E3) will be listed separately.
Previous and concomitant therapies will be presented per treatment group without 
consideration of time intervals and treatment periods.
Laboratory data will be compared to their reference ranges. Values outside the reference 
range as well as values defined as possibly clinically significant will be highlighted in the 
listings. Additionally, differences from baseline will be evaluated.
Vital signs or other safety-relevant data will be assessed with regard to possible on-treatment 
changes from baseline.
Relevant ECG findings will be reported as AEs.
7.4
INTERIM ANALYSES
No interim analysis is planned.

HANDLING OF MISSING DATA
7.5.1
Safety
It is not planned to impute missing values for safety parameters.
7.5.2
Pharmacokinetics
Handling of missing PK data will be performed according to the relevant Corporate 
Procedure 
.
PK parameters that cannot be reasonably calculated based on the available drug 
concentration-time data will not be imputed.
7.6
RANDOMISATION
Subjects will be randomised to one of the 2 treatment sequences in a 1:1 ratio. The block size 
will be documented in the CTR.
The sponsor will arrange for the randomisation as well as packaging and labelling of trial 
medication. The randomisation list will be generated using a validated system that uses a 
pseudo-random number generator and a supplied seed number so that the resulting allocation 
is both reproducible and non-predictable.
The randomisation list will contain additional blocks to allow for subject replacement (refer 
to Section 3.3.5).
7.7
DETERMINATION OF SAMPLE SIZE
It is planned to enter a total of 12 subjects in the trial, because this sample size is considered 
sufficient to achieve the aims of this exploratory trial.

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..
