Criteria for safety:
Adverse events (AEs) including clinically relevant findings from the physical 
examination, safety laboratory tests, 12-lead electrocardiogram (ECG), vital signs 
(blood pressure [BP], pulse rate [PR]) 
Statistical methods:
Absolute bioavailability (F) will be estimated by the ratio of the geometric means 
(tablet/infusion) for the dose normalized primary endpoints separately for Day 1 and 
Day 28. Additionally, its two-sided 90% confidence interval (CI) will be provided. 
This method corresponds to the two one sided t-tests procedure, each at the 5% 
significance level. Since the main focus is on estimation and not testing, an 
acceptance range was not specified. The statistical model will be an ANOVA on the 
logarithmic scale including the fixed effect for ‘formulation’ and ‘subject’ as a 
random effect. CIs will be calculated based on the residual error from ANOVA.
In addition, the absolute bioavailability factor F will be calculated for each subject 
on Day 1 and Day 28.
Descriptive statistics will be calculated for all endpoints.

1.
Screening includes subject information, informed consent, physical examination, check of vital signs, ECG, safety 
laboratory (including drug and virus screening), demographics (including determination of body height and weight, 
BMI, smoking status and alcohol history), relevant medical history, concomitant therapy and review of 
inclusion/exclusion criteria.
2.
The time is approximate; the procedure is to be performed within a time window of 3 h prior to drug administration.
After start of treatment, further PK blood sampling (trough level) within 30 minutes before next scheduled dosing.
3.
If several actions are indicated at the same time point, the intake of meals will be the last action.
4.
Subjects are to be fasted for at least 10 h before sample is taken.
5.
Only urine drug and alcohol screening will be done at this time point.
6.
End-of-trial (EOT) examination to be performed on Day 34-41, EOT examination includes physical examination, vital 
signs, ECG, safety laboratory, recording of AEs and concomitant therapies.
7.
On Days 3 to 6, 8 to 13, 15 to 20 and 22 to 25, subjects are allowed to take their study medication at home if deemed 
appropriate by the investigator. Compliance of medication intake will be monitored by subject diary and daily phone 
contact between subject and site. The scheduled time for drug intake throughout the study is 08:00 (applies for intake at 
home and at the trial site). 
8.
Pharmacogenomic sample.
9.
For definition of the individual subject’s end of trial see Section 6.2.3.
10. Samples for an individual subject beyond 5 h after end of infusion will be only analyzed if for this subject the plasma 
level of [C-14]BI 1467335 at this time point (i.e., 6:15) is still above LOQ.
11. Subjects will be hospitalized from admission on Day 25 to Day 32.

RATIONALE, OBJECTIVES, AND BENEFIT - RISK 
ASSESSMENT
2.1
RATIONALE FOR PERFORMING THE TRIAL
This trial is intended to examine the absolute oral bioavailability of BI 1467335 using an iv
[C-14] microtracer approach. The data are considered necessary to further support the 
understanding of the pharmacokinetics of BI 1467335. Due to the time dependent non-linear 
kinetics of BI 1467335, systemic exposures on Day 28 cannot be predicted from Day 1 
kinetics, (IB [c04751792]).Therefore absolute oral bioavailability using an iv [C-14] 
microtracer dose will be determined on Day 1 and on Day 28 following a single (Day 1) and 
multiple dose treatment (Day 1 to 28) with an oral unlabelled dose of 10 mg of BI 1467335
q.d.
2.2
TRIAL OBJECTIVES
The primary objective of this trial is to investigate the absolute bioavailability of BI 1467335 
with an intravenous microdose formulation containing labelled [C-14] BI 1467335 and an 
unlabelled oral tablet formulation of BI 1467335 in healthy male subjects.
The secondary objective is the evaluation of additional pharmacokinetic parameters following 
the two treatments.
The assessment of safety and tolerability will be an additional objective of this trial.
A description of the endpoints to be determined, and the observations along with specific 
information as how to collect the data for that information, is provided in Section 5.
2.3
BENEFIT - RISK ASSESSMENT
Participation in this study is without any (therapeutic) benefit for healthy subjects. Their 
participation in the study, however, is of major importance to the development of the
compound. The subjects are exposed to the risks of the study procedures and the risks related 
to the exposure to the trial medication.

DESCRIPTION OF DESIGN AND TRIAL POPULATION
3.1
OVERALL TRIAL DESIGN AND PLAN
The study will be performed as an open-label, non-randomised, single arm, multiple dose trial 
in healthy male subjects to define from the systemic exposure from the oral dose (T1, film 
coated tablet) and that following the iv infusion (T2, microtracer infusion). The resulting 
data, per subject, will be dose normalised then the absolute oral bioavailability (%) of the
10 mg tablet on Days 1 and 28 will be calculated. For Day 1, (AUC0-∞/Dose)oral/
((AUC0-∞/Dose)iv*100 and for Day 28 (AUC/Dose)oral/((AUC0-∞,28/Dose)iv*100.
The treatments will be a 10 mL intravenous infusion of 50 µg BI 1467335 free base (T2); 
using on Day 1 a mixture of 41.15 µg unlabelled BI 1467335 and 8.85 µg [C-14] BI 1467335
(corresponding to 46.50 µg and 10 µg of salt respectively) and on Day 28 a mixture of 45 µg
unlabelled BI 1467335 and 5 µg [C-14] BI 1467335 free base (corresponding to 50.85 µg and 
5.65 µg of salt respectively). The oral treatment (T1) will consist of two 5 mg film-coated 
tablets (dose strength based on free base) administered once daily for 28 days. On Day 1 and 
Day 28, both treatments are given in fasted state. 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.

The analyses of BI 1467335 concentrations in plasma will be performed at the Department of 
Drug Metabolism and Pharmacokinetics, BI Pharma GmbH & Co. KG, Biberach, Germany. 
Accelerator mass spectrometry (AMS) analysis will be conducted 
 
On-site monitoring will be performed by BI or a contract research organisation appointed by 
BI.
Data management and statistical evaluation will be done by BI or a contract research 
organisation appointed by BI according to BI SOPs.
Tasks and functions assigned in order to organise, manage, and evaluate the trial are defined 
according to BI SOPs. A list of responsible persons and relevant local information can be 
found in the ISF.
3.2
DISCUSSION OF TRIAL DESIGN, INCLUDING THE CHOICE OF 
CONTROL GROUP
Due to the time dependent non-linear kinetics of BI 1467335, systemic exposures on Day 28 
cannot be predicted from Day 1 kinetics, (IB [c04751792]).Therefore the absolute oral 
bioavailability will be determined on two occasions following single (Day 1) and multiple 
oral dose treatment (Day 28) following 10 mg of BI 1467335 qd (2 film-coated tablets of 
5 mg dose strength), the maximum therapeutic dose used in ongoing phase II studies.
The same subject will receive a 14C labelled microtracer infusion on Day 1 after a single oral
dose and on Day 28 after multiple oral doses. Thus, the oral bioavailability on Day 1 and 28 
will be calculated for each subject on each day. As the iv infusion is given at the geometric 
mean tmax of the oral dose, this accounts for the observed non-proportionality in systemic 
exposure observed between Days 1 and 28.
[C-14] BI 1467335 is unlikely to exhibit any detectable isotope effects (see Section 2.3).
The open-label treatment is not expected to bias results, since the primary study endpoints are 
derived from quantitative measurements of plasma concentrations of the analyte following 
oral and iv dosing.
3.3
SELECTION OF TRIAL POPULATION
It is planned that at least 10 healthy male subjects will enter the study (maximum number of 
n=12 subjects) to have at least 8 evaluable subjects. They will be recruited from the 
volunteers' pool of the trial site or, if necessary, via advertisement. 
The current trial is designed to investigate the absolute oral bioavailability of BI 1467335
following 10 mg oral dosing. Healthy male subjects are an ideal population for the objectives 
of this trial, since they provide relatively stable physiological, biochemical and hormonal 
conditions, i.e. the absence of disease-related variations and relevant concomitant 
medications.

3.3.4
Removal of subjects from therapy or assessments
3.3.4.1
Removal of individual subjects
An individual subject is to be removed from the trial if:
1. The subject withdraws consent for trial treatment or trial participation, without the need to 
justify the decision
2. The subject needs to take concomitant drugs that interfere with the investigational  
product or other trial medication
3. The subject is no longer able to participate for other medical reasons (such as surgery, 
adverse events, or diseases)
4. The subject shows an elevation of AST and/or ALT ≥3-fold ULN combined with an 
elevation of total bilirubin ≥2-fold ULN (measured in the same blood sample) and/or 
needs to be followed up according to the ‘DILI checklist’ provided in the ISF.
5. A subject can also be removed from the trial if eligibility criteria are being violated or if 
the subject fails to comply with the protocol (for instance, by non-adherence to dietary 
rules, or non-attendance at study assessments).
If a subject is removed from or withdraws from the trial prior to first administration of trial 
medication, the data of this subject will not be entered in the case report form (CRF) or trial 
database and will not be reported in the clinical trial report (CTR). If a subject is removed 
from or withdraws from the trial after first administration of trial medication, this will be 
documented and the reason for discontinuation must be recorded in the CRF. In this case, the 
data will be included in the CRF/trial database and will be reported in the CTR. At the time 
of discontinuation a complete end of trial examination will be performed if possible and the 
information will be recorded in the CRFs. If the discontinuation occurs before the end of the 
REP (see Section 5.2.2.2), the discontinued subject should if possible be questioned for AEs 
and concomitant therapies at or after the end of the REP in order to ascertain collection of 
AEs and concomitant therapies throughout the REP, if not contrary to any consent 
withdrawal of the subject. These discontinuations will be discussed in the CTR.
3.3.4.2
Discontinuation of the trial by the sponsor
Boehringer Ingelheim reserves the right to discontinue the trial overall or at a particular trial 
site at any time for any of the following reasons:
1. New toxicological findings or serious adverse events invalidate the earlier positive 
benefit-risk-assessment. More specifically, the trial will be terminated if at least one drug-
related serious adverse event is reported that is considered to be unacceptable. In this 
case, collection of pharmacokinetic samples and other scheduled activities should 
continue, if possible without undue risk to already dosed volunteers, but no further 
administrations of investigational drug will be done.
2. The expected enrolment goals overall are not met
3. Violation of GCP, or the CTP, or the contract with BI by a trial site or investigator, 
disturbing the appropriate conduct of the trial

Duration of use:
Two single infusions (Day 1 and Day 28), infused over 
15 minutes
4.1.2
Method of assigning subjects to treatment groups
This is an open-label, single arm Phase I, single- and multiple dose study. All subjects receive 
the same dose. Each subject will be assigned a subject number prior to dosing on Day 1 of 
Visit 2.
Subject numbers will be
for the maximum number of twelve planned subjects and 
in case subject replacement is necessary (see Section 3.3.5). 
Once a subject number has been assigned, it cannot be reassigned to any other subject. 
The randomisation procedure is described in Section 7.5.
4.1.3
Selection of doses in the trial
The oral dose of 10 mg BI 1467335 (calculated as free base) is below the already tested 
highest oral dose of 20 mg of BI 1467335 for 4 weeks in healthy subjects. In healthy 
volunteers, this dose was safe and well-tolerated (Section 1.2). 
 
An oral 
dose of 10 mg, administered either as single or multiple dose, is considered adequate for the 
objectives of the current trial. 
The iv dose on Day 1 and Day 28 administered as infusion will include 14C radiolabelled 
BI 1467335. The radiolabelled dose has been selected to provide sufficient analytical 
sensitivity, (Accelerator Mass Spectrometry), in this microtracer study while not exceeding 
the threshold of negligible radioactive burden, see Section 2.3.
4.1.4
Drug assignment and administration of doses for each subject
All subjects will receive the same treatment. Treatment with non-radiolabelled oral 
compound (film-coated tablets) will consist of 10 mg q.d. from Day 1 to Day 28. On Day 1 
and Day 28 the non-radiolabelled medication will be administered to a subject in the sitting 
position under supervision of the investigator or an authorised designee. Volunteer will drink 
240 mL of non-sparkling water.
In principal, the so-called four-eye principle (two-person rule) should be applied for 
administration of trial medication at the study site, while intake under ambulatory conditions 
will be monitored by phone contacts between study site and subject. 
On Day 1 and Day 28 lunch will be given 4 h postdose. During the first 4 h after drug 
administration (only on Day 1 and Day 28), subjects 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 examinations (in particular for the microtracer infusion) or if necessary for any 
medical reasons (e.g., adverse events). For restrictions with regard to diet and fluid intake
during the investigational period see Section 4.2.2.2.
Start and time of the infusion will be recorded.
For administration of the microtracer infusion on Day 1 and Day 28 (duration of infusion: 
15 minutes), an intravenous indwelling catheter is placed into an arm vein of the subject and 
will be kept patent with a saline infusion. A second indwelling catheter used for collection of 
blood samples will be placed on the contralateral arm.
4.1.5
Blinding and procedures for unblinding
No blinding will be performed because the treatments are distinguishable from each other. 
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, since it is an open-label trial.
4.1.6
Packaging, labelling, and re-supply
Non-labelled drug supplies will be provided by the Department of Pharmaceutical 
Development of Boehringer Ingelheim Pharma GmbH & Co. KG, Biberach, Germany.
Radiolabelled drug product manufacturing is provided by 
. 
The clinical trial supply consists of containers holding the trial medication which are labelled 
with trial identification. Investigational Drug Products will be labelled according to GMP 
Annex 13 / EU GMP Guideline and local drug law. 
Examples of the labels will be available in the ISF.
No re-supply is planned.
4.1.7
Storage conditions
Drug supplies will be kept in their original packaging and in a secure limited access storage 
area according to the recommended (labelled) storage conditions. Where necessary, a 
temperature log must be maintained to make certain that the drug supplies are stored at the 
correct temperature. If the storage conditions are found to be outside the specified range, the 
local clinical monitor (as provided in the list of contacts) is to be immediately contacted.
4.1.8
Drug accountability
 pharmacy will deliver the investigational drugs to the investigator upon availability of a 
valid prescription from the investigator.
The investigator will not order the drugs from the 
 pharmacy before the following 
requirements are fulfilled:

VARIABLES AND THEIR ASSESSMENT
5.1
EFFICACY - CLINICAL PHARMACOLOGY
5.1.1
Endpoints of efficacy
No efficacy endpoints will be evaluated in this trial.
5.1.2
Assessment of efficacy
Not applicable.
5.2
SAFETY
5.2.1
Endpoints of safety
Safety and tolerability of the investigational drug will be assessed based on:

Adverse events (including clinically relevant findings from the physical examination)

Safety laboratory tests

12-lead ECG

Vital signs (blood pressure, pulse rate)
These parameters will be evaluated in a descriptive way only, and are therefore considered to 
be ‘further parameters of interest’. A confirmatory analysis is not planned (see Section 7.3).
5.2.2
Assessment of adverse events
5.2.2.1
Definitions of adverse events
Adverse event
An adverse event (AE) is defined as any untoward medical occurrence in a patient or clinical 
investigation subject administered a medicinal product and which does not necessarily have 
to have a causal relationship with this treatment.
An AE can therefore be any unfavourable and unintended sign (including an abnormal 
laboratory finding), symptom, or disease temporally associated with the use of a medicinal 
product, whether or not considered related to the medicinal product.
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 or 

requires prolongation of existing hospitalisation,

results in persistent or significant disability or incapacity, or

is a congenital anomaly/birth defect, 
or 

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’
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.
Cancers of new histology and exacerbations of existing cancer must be classified as a serious 
event regardless of the duration between discontinuation of the drug and must be reported as 
described in 5.2.2.2, subsections ‘AE collection’ and ‘AE reporting to sponsor and timelines’.
The latest list of ‘Always Serious AEs’ can be found in the RDC system. These events should 
always be reported as SAEs as described above.
Adverse events of special interest (AESIs)
The term AESI relates to any specific AE that has been identified at the project level as being 
of particular concern for prospective safety monitoring and safety assessment within this trial, 
e.g. the potential for AEs based on knowledge from other compounds in the same class. 
AESIs need to be reported to the sponsor’s Pharmacovigilance Department within the same 
timeframe that applies to SAE, please see Section 5.2.2.2.
The following are considered as AESIs in this trial:

Hepatic injury
A hepatic injury is defined by the following alterations of hepatic laboratory 
parameters: 
o
an elevation of AST and/or ALT ≥3-fold ULN combined with an elevation of 
total bilirubin ≥2-fold ULN measured in the same blood sample, and/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 these parameters are analysed, if necessary in an unscheduled blood test. 
Should the results meet the criteria of hepatic injury alert, the procedures described in 
the DILI checklist should be followed.
Intensity (severity) of AEs
The intensity (severity) of adverse events should be classified and recorded in the (e)CRF
according to the Common Terminology Criteria for Adverse Events (CTCAE) Version 4.03 
dated 14 June 2010 [R10-4848] in the (e)CRF.
Causal relationship of AEs
Medical judgment should be used to determine the relationship, considering all relevant 
factors, including pattern of reaction, temporal relationship, de-challenge or re-challenge, 
confounding factors such as concomitant medication, concomitant diseases and relevant 
history.
Arguments that may suggest that there is a reasonable possibility of a causal relationship 
could be:

The event is consistent with the known pharmacology of the drug 

The event is known to be caused by or attributed to the drug class.

A plausible time to onset of the event relative to the time of drug exposure.

Evidence that the event is reproducible when the drug is re-introduced

No medically sound alternative aetiologies that could explain the event (e.g. pre-
existing or concomitant diseases, or co-medications).

The event is typically drug-related and infrequent in the general population not 
exposed to drugs (e.g. Stevens-Johnson syndrome).

An indication of dose-response (i.e. greater effect size if the dose is increased, smaller 
effect size if dose is diminished).
Arguments that may suggest that there is no reasonable possibility of a causal relationship 
could be:

No plausible time to onset of the event relative to the time of drug exposure is evident 
(e.g. pre-treatment cases, diagnosis of cancer or chronic disease within days / weeks 
of drug administration; an allergic reaction weeks after discontinuation of the drug 
concerned).

Continuation of the event despite the withdrawal of the medication, taking into 
account the pharmacological properties of the compound (e.g. after 5 half-lives). Of 
note, this criterion may not be applicable to events whose time course is prolonged 
despite removing the original trigger.

Additional arguments amongst those stated before, like alternative explanation (e.g. 
situations where other drugs or underlying diseases appear to provide a more likely 
explanation for the observed event than the drug concerned).

Disappearance of the event even though the study trial treatment continues or remains 
unchanged.

5.2.2.2
Adverse event collection and reporting
AE collection
Upon enrolment into a trial, the subject’s baseline condition is assessed (for instance, by 
documentation of medical history/concomitant diagnoses), and relevant changes from 
baseline are noted subsequently. 
Subjects will be required to report spontaneously any AEs as well as the time of onset, end, 
and intensity of these events. In addition, each subject will be regularly assessed by the 
medical staff throughout the clinical trial and whenever the investigator deems necessary. 
As a minimum, subjects will be questioned for AEs (and concomitant therapies) at the time 
points indicated in the Flow Chart. Assessment will be made using non-specific questions 
such as ‘How do you feel?’. Specific questions will be asked wherever necessary in order to 
more precisely describe an AE.
A careful written record of all AEs shall be kept by the investigator in charge of the trial. 
Records of AEs shall include data on the time of onset, end time, and intensity of the event as 
well as any treatment or action required for the event and its outcome.
The following must be collected and documented on the appropriate CRF(s) by the 
investigator:

From signing the informed consent onwards  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 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.

The REP for BI 1467335, when measurable drug levels or PD effects are still likely to be 
present after the last administration, is not known for this clinical trial. Therefore, all AEs 
reported until the end of trial examination (last per protocol contact) will be considered on 
treatment (please see Section 7.3.3).
AE reporting to sponsor and timelines
The Investigator must report SAEs, AESIs, and non-serious AEs which are relevant for the 
reported SAE or AESI, on the BI SAE form via fax immediately (within 24 hours) to the 
sponsor’s unique entry point (country specific contact details will be provided in the ISF). 
The same timeline applies if follow-up information becomes available. In specific occasions 
the Investigator could inform the sponsor upfront via telephone. This does not replace the 
requirement to complete and fax the BI SAE form. 
With receipt of any further information to these events, a follow-up SAE form has to be 
provided. For follow-up information the same rules and timeline apply as for initial 
information.
Information required
For each AE, the investigator should provide the information requested on the appropriate 
eCRF pages and the BI SAE form, if applicable. The investigator should determine the causal 
relationship to the trial medication. 
The following should also be recorded as an (S)AE in the CRF and 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.
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.

Assessment of safety laboratory parameters
For the assessment of laboratory parameters, blood and urine samples will be collected by the 
trial site at the time points indicated in the Flow Chart after the subjects have fasted for at 
least 10 h. Subjects do not have to be fasted for drug screening and for infectious serology at 
the discretion of the investigator or designee. Fasting is not required at the discretion of the 
investigator or designee for retests.
The parameters that will be determined are listed in Tables 5.2.3: 1 and 5.2.3: 2. Reference 
ranges will be provided in the ISF. 
Manual differential white blood cell count or urine sediment examinations will only be 
performed if there is an abnormality in the automatic blood cell count or in the urinalysis, 
respectively.

All ECGs will be recorded for a 10-sec duration after the subjects have rested for at least 
5 min in a supine position. ECG assessment will always precede all other study procedures of 
the same time point (except blood drawing from an intravenous cannula which is already in 
place) to avoid impact of sampling on the ECG quality.
All ECGs will be stored electronically. Electrode placement will be performed according to 
the method of Wilson, Goldberger and Einthoven. 
All locally printed ECGs will be evaluated by the investigator or a designee. ECGs may be 
repeated for quality reasons (like alternating current artefacts, muscle movements, electrode 
dislocation) and the repeated ECG will be used for analysis. Additional (unscheduled) ECGs 
may be collected by the investigator for safety reasons. 
Abnormal findings will be reported as AEs (during the trial) or baseline conditions (at 
screening) if judged clinically relevant by the investigator. Any ECG abnormalities will be 
monitored carefully and, if necessary, the subject will be removed from the trial and will 
receive the appropriate medical treatment. 
5.2.5
Assessment of other safety parameters
5.2.5.1
Vital signs
Systolic and diastolic blood pressures (BP) as well as pulse rate (PR) or heart rate (heart rate 
is considered to be equal to pulse rate) will be measured by a blood pressure monitor 
(Dinamap Pro 100, GE Medical Systems) at the times indicated in the Flow Chart, after 
subjects have rested for at least 5 min in a supine position. All recordings should be made 
using the same type of blood pressure recording instrument on the same arm if possible.
5.2.5.2
Medical examinations
At the screening visit, the medical examination will include documentation of subject 
information, informed consent, demographics including height and body weight, smoking 
and alcohol history, relevant medical history and concomitant therapy, review of inclusion
and exclusion criteria, review of vital signs (BP, PR), 12-lead ECG, laboratory tests, and a 
physical examination. At the end of trial examination, it will include review of vital signs, 
12-lead ECG, laboratory tests, and a physical examination.

APPROPRIATENESS OF MEASUREMENTS
All measurements performed during this trial are standard measurements and will be 
performed in order to monitor subjects’ safety and to determine pharmacokinetic parameters 
in an appropriate way. The scheduled measurements will allow monitoring of changes in vital 
signs, standard laboratory values, and ECG parameters that might occur as a result of 
administration of trial medication. The safety assessments are standard, are accepted for 
evaluation of safety and tolerability of an orally administered drug, and are widely used in 
clinical trials. The pharmacokinetic parameters and measurements outlined in Section 5.5 are 
generally used assessments of drug exposure in human mass-balance trials.
5.5
DRUG CONCENTRATION MEASUREMENTS AND 
PHARMACOKINETICS
Date and clock time of drug administration and pharmacokinetic sampling will be recorded in 
the eCRF. For drug intake at home the entries from subject’s diary will be transferred to the 
eCRF.

5.5.2.1
Plasma sampling for pharmacokinetic analysis
For quantification of BI 1467335 plasma concentrations, approx. 3 mL of blood will be taken 
from an antecubital or forearm vein into a K2-EDTA (tripotassium ethylendiaminetetraacetic 
acid)-anticoagulant blood drawing tube at the times indicated in the Flow Chart.

For quantification of [C-14] BI 1467335 plasma concentrations, an additional 3 mL K2-
EDTA tube needs to be collected as indicated in the Flow Chart. Blood will be withdrawn by 
means of either an indwelling venous catheter or by venipuncture with a metal needle.
All blood samples will be centrifuged 
 
 
 
 
 
 
 The remaining plasma will be used as analytical back-up sample. Until transfer on 
dry ice to the analytical laboratory, the plasma samples will be stored frozen and in upright 
position at about –20°C or below at the clinical site and at the analytical laboratory until 
analysis.
For detailed description of blood sampling, sample handling, sample preparation, sample 
storage, tube labelling and sample shipment refer to the laboratory manual.
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) 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. 
At a minimum, the sample tube labels should list the following information: BI trial number, 
subject number, visit, planned sampling time, analyte and aliquot. Further information such 
as matrix may also be provided. 
The study samples will be discarded after completion of the additional investigations but not 
later than 5 years upon the final study report has been signed the analytical laboratory after 
the bioanalyst has acknowledged safe arrival of the first aliquot.
5.5.3
Analytical determinations
5.5.3.1
Analytical determination of analyte plasma concentration
Cold BI 1467335 concentrations in plasma will be determined by a validated LC-MS/MS 
(liquid chromatography coupled to tandem mass spectrometry) assay.
[C-14] BI 1467335 will be determined by a validated AMS (accelerator mass spectrometry)
assay.

INVESTIGATIONAL PLAN
6.1
VISIT SCHEDULE
Exact times of measurements outside the permitted time windows will be documented. The 
acceptable time windows for screening and end of trial examination are given in the Flow 
Chart.
Study measurements and assessments scheduled to occur ‘before’ trial medication 
administration are to be performed and completed within a 3 h-interval prior to the trial drug 
administration. 
The acceptable deviation from the scheduled time for vital signs, ECG and safety laboratory 
tests will be ± 30 min on Day 1 (SD) or on Day 28 (MD) and ± 90 min on all other days of 
Visit 2.
If scheduled in the Flow Chart at the same time as a meal, 12-lead ECG recordings, vital 
signs and blood samplings, have to be done first. Furthermore, if several measurements 
including venipuncture are scheduled for the same time, venipuncture should be the last of 
the measurements due to its inconvenience to the subject and possible influence on 
physiological parameters.
For planned individual plasma and blood concentration sampling times refer to the Flow 
Chart. While these nominal times should be adhered to as closely as possible, the actual 
sampling times will be recorded and used for determination of pharmacokinetic 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.
6.2
DETAILS OF TRIAL PROCEDURES AT SELECTED VISITS
6.2.1
Screening period
Screening visit is defined as Visit 1.
After having been informed about the trial, all subjects will give their written informed 
consent in accordance with GCP and local legislation prior to enrolment in the study.
For information regarding laboratory tests (including drug and virus screening), ECG, vital 
signs, and physical examination, refer to Sections 5.2.3 to 5.2.5.
6.2.2
Treatment period
Each subject will receive on Day 1 a single 10 mL infusion of 50 µg BI 1467335 (C-14) 
(containing 8,85 µg [C-14] BI 1467335 free base and 41,15 µg of BI 1467335 free base) over 
a period of 15 minutes, 1 h after oral intake of 10 mg of BI 1467335 (film-coated tablets).
All subjects will continue to receive a single oral dose of 10 mg BI 1467335 from Day 2
up to Day 28. On Day 28 all subjects will again receive a single 10 mL infusion of 50 µg 
BI 1467335 (C-14) (containing 5 µg [C-14] BI 1467335 free base and 45 µg of BI 1467335

free base) over a period of 15 minutes, 1 h after oral intake of 10 mg of BI 1467335 free base
(film-coated tablets). 
On Day 6, Day 13 and Day 20 (due to assessments and dispensing of study medication in the 
morning of the next day) participants will be admitted to the trial site and kept under close 
medical surveillance as indicated in the Flow Chart and Section 5.2.5.
For details on time points and procedures for collection of plasma samples for PK analysis, 
refer to Flow Chart and Section 5.5.2.
The safety measurements performed during the treatment period are specified in Section 5.2
of this protocol and in the Flow Chart. For details on time points for all other trial procedures, 
refer to the Flow Chart. AEs and concomitant therapy will be assessed continuously from 
screening until the end of trial examination.
6.2.3
End of trial period
For AE assessment, laboratory tests, recording of ECG and vital signs, and physical 
examination during the end of trial period, see Sections 5.2.2 to 5.2.5.
Subjects who discontinue treatment before the end of the planned treatment period should 
undergo the end of trial visit.
All abnormal values (including laboratory parameters) that are judged clinically relevant by 
the investigator will be monitored using the appropriate tests until a return to a medically 
acceptable level is achieved. (S)AEs persisting after subject’s end of trial must be followed 
up until they have resolved, have been sufficiently characterised, or no further information 
can be obtained. 
The end of the trial as a whole is defined by the ‘last regular visit completed by last subject’ 
or ‘end date of the last open AE’ or ‘date of the last follow-up test’ or ‘date of an AE has 
been decided as sufficiently followed-up’, whichever is latest.

STATISTICAL METHODS AND DETERMINATION OF
SAMPLE SIZE
7.1
STATISTICAL DESIGN – MODEL
7.1.1
Objectives
The primary objective of this trial is to investigate the absolute bioavailability of BI 1467335 
with an intravenous microdose formulation containing labelled [C-14] BI 1467335 
(reference, R) and an unlabelled oral tablet formulation of BI 1467335 (test, T) in healthy 
male subjects.
The study will be conducted as an open-label, single arm, multiple oral dose trial. The trial 
design consists of an intravenous microtracer dose being administered at the gMean tmax of 
the oral dose, which allows accurate estimates of absolute bioavailability. This means that the
intersubject variability is removed from the comparison between formulations, as well as the 
day to day variability within one subject. Due to the time dependent kinetics, the absolute 
bioavailability will be analysed on Day 1 and Day 28. The trial will be evaluated statistically 
by use of an appropriate linear model.
The evaluation of further pharmacokinetic parameters of BI 1467335 as well as the 
assessment of safety and tolerability will be additional objectives of this trial, and will be 
evaluated by descriptive statistics. Inferential statistics is not planned.
7.1.2
Endpoints
Absolute oral bioavailability is to be determined for Day 1 and Day 28, on the basis of the 
individually dose normalized primary pharmacokinetic endpoints (see Section 5.5.1). Other 
PK endpoints are mentioned in Section 5.5.1.3 and will be analysed descriptively only.
Safety and tolerability will be determined on the basis of the parameters specified in 
Section 5.2.1.
7.1.3
Model
The statistical model used for the analysis of primary endpoints will be an ANOVA (analysis 
of variance) model on the logarithmic scale. This model will include effects accounting for 
the following sources of variation: ‘subject’ and ‘formulation’. The effect ‘subjects’ will be 
considered as random, whereas the effect ‘formulation’ will be considered as fixed. 
The model is described by the following equation:
ykm = + sm + k + ekm, where
ykm = logarithm of response (dose normalized primary endpoint, see Section 5.5.1) 
measured on subject m receiving formulation k,
= the overall mean,

sm = the effect associated with the mth subject, m = 1, 2, ..., n
k = the kth formulation effect (either tablet or i.v.), k = 1, 2,
ekm = the random error associated with the mth subject who received
formulation k.
7.2
NULL AND ALTERNATIVE HYPOTHESES
It is not planned to test any statistical hypotheses in a confirmatory sense. 
The absolute oral bioavailability of BI 1467335 by comparing 8,85 µg (Day 1) or 5 µg 
(Day 28) intravenously administered [C-14] BI 1467335 free base with an oral dose of 10 mg
of BI 1467335free base after single and multiple oral doses will be estimated by the ratios of 
the geometric means (test/reference) for the dose normalized primary PK endpoints. 
Additionally, their two-sided 90% confidence intervals (CIs) will be provided. This method 
corresponds to the two one-sided t-tests procedure, each at the 5% significance level. 
Confidence intervals will have to be interpreted in the perspective of the exploratory 
character of the trial, i.e. confidence intervals are considered as interval estimates for effects.
7.3
PLANNED ANALYSES
Adherence to the protocol (such as inclusion/exclusion criteria, times of measurement, 
compliance with intake of trial medication, treatment dispensing errors, prohibited 
concomitant medication, completeness and consistency of data) will be checked. Important 
protocol violations will be identified no later than in the report planning meeting (RPM) and 
provided in the trial statistical analysis plan (TSAP).
The following analysis sets will be defined for this trial:

Treated set (TS):
This subject set includes all subjects who were documented to have received one dose 
of study drug. This is the full analysis set population in the sense of ICH-E9.

PK analysis set (PKS):
This subject set includes all subjects from the TS who provide at least one primary PK 
endpoint value that is judged as PK evaluable and is not affected by protocol 
violations relevant to the statistical evaluation of PK endpoints. Thus, a subject will 
be included in the PKS, even if he contributes only one PK endpoint value for one 
formulation (at Day 1 or Day 28) to the statistical assessment.
Whether a PK endpoint is evaluable or a protocol violation is relevant will be decided no later
than at the RPM.

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
Pharmacokinetic endpoint values of a subject will be included in the analysis if they are not
flagged for exclusion, e.g. due to PK non-evaluability or a protocol violation relevant to the 
evaluation of PK endpoints.
7.3.1
Primary analyses
The pharmacokinetic endpoints listed in Section 5.5.1 will be calculated according to the 
BI Standard Operating Procedure (SOP) ‘Standards and processes for analyses performed 
within Clinical Pharmacokinetics/Pharmacodynamics’ (001-MCS-36-472).
Plasma concentration data and derived 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 RPM) 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.
Plasma concentrations and/or derived parameters of a subject will be considered as non-
evaluable, if for example:

The subject experiences emesis at or before two times median tmax. Median tmax is to 
be taken either from the median tmax for the reference product or from median tmax for 
the test product, depending on whether the subject had experienced emesis after taken 
the test or the reference product. Median tmax is to be determined excluding the 
subjects experiencing emesis.  

Missing samples/concentration data at important phases of PK disposition curve.
The primary PK parameters Cmax and AUC0-∞on Day 1 and Cmax,28, AUC0-24,28 (after oral 
administration) and AUC0-∞,28 (after intravenous administration) on Day 28 (refer to Section 
5.5.1) of BI 1467335 in plasma will be dose normalized and then log-transformed (natural 
logarithm) prior to fitting the ANOVA model. The difference between the expected means 
for log(Test)-log(Reference) will be estimated by the difference in the corresponding least 
square means (point estimate) and two-sided 90% confidence intervals based on the t-
distribution will be computed. 
These quantities will then be back-transformed to the original scale to give the point
estimator (geometric mean) and 90% confidence interval estimates for the intra-subject ratio
of the geometric means for treatments test and reference.

This will be done for Day 1 and Day 28 separately, thus the analysis variables are the 
following:
Day 1 for Cmax: 
normalised Cmax after oral and intravenous administration
Day 1 for AUC: 
normalised AUC0-∞after oral and intravenous administration
Day 28 for Cmax: 
normalised Cmax, 28 after oral and intravenous administration
Day 28 for AUC: 
normalised AUC0-24,28 after oral administration and 
normalised AUC0-∞, 28 after intravenous administration
The primary analysis will be based on the pharmacokinetic analysis set (see Section 7.3).
7.3.2
Secondary analyses
As a sensitivity analysis, the ANOVA performed as primary analysis will be repeated with 
subject as fixed effect instead of random effect. The results will be presented in the same 
manner as for the primary analyses.
The secondary parameters (refer to Section 5.5.1) will be calculated according to the BI SOP 
‘Standards and processes for analyses performed within Clinical Pharmacokinetics/ 
Pharmacodynamics’ (001-MCS-36-472) and will statistically be assessed using the same 
methods as described for the primary endpoints.
The following descriptive statistics will be calculated for primary and secondary PK 
parameters and for further endpoints: N, arithmetic mean, standard deviation, minimum, 
median, maximum, arithmetic coefficient of variation, geometric mean, and geometric 
coefficient of variation. The data format for descriptive statistics of concentrations will be 
identical with the data format of the respective concentrations. The descriptive statistics of 
PK parameters will be calculated using the individual values with the number of decimal 
places as provided by the evaluation program. Then the individual values as well as the 
descriptive statistics will be reported with 3 significant digits in the clinical trial report.
7.3.3
Safety analyses
Safety will be assessed for the endpoints listed in Section 5.2.1. All treated subjects (that is,
all subjects who received at least one dose of study drug), will be included in the safety
analysis. Safety analyses will be descriptive in nature and will be based on BI standards. No 
hypothesis testing is planned.
The analyses will be done by ‘treatment at onset’.
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 ECG, vital signs, or laboratory parameters) or AEs will be assigned 
to treatments (see Section 4.1) based on the actual treatment at the planned time of the 
measurement or on the recorded time of AE onset (concept of treatment emergent AEs).
Therefore, measurements planned or AEs recorded prior to first intake of trial medication will

be assigned to 'screening', those between first trial medication intake until the 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.
Additionally, further treatment intervals (analysing treatments) may be defined in order to 
provide summary statistics for time intervals, such as combined treatments, on-treatment 
totals or periods without treatment effects (such as screening). Adverse events will be coded 
using the Medical Dictionary for Regulatory Activities (MedDRA). Frequency, severity and 
causal relationship of AEs will be tabulated by treatment, system organ class and preferred 
term. SAEs, AESIs (see Section 5.2.2.1) and other significant AEs (according to ICH E3) 
will be listed separately.
Laboratory data will be compared to their reference ranges. Values outside the reference 
range as well as values defined as clinically relevant will be highlighted in the listings. 
Additionally, differences from baseline will be evaluated.
For vital signs, the differences from baseline will be evaluated.
Relevant ECG findings will be reported as AEs.
7.3.4
Interim analyses
No interim analysis is planned.
7.3.5
Pharmacokinetic analyses
The pharmacokinetic parameters listed in Section 5.5.1 for drug BI 1467335 will be 
calculated according to the relevant SOP of the Sponsor (001-MCS-36-472).
Subjects who are not included in the PKS (refer to Section 7.3.1) will be reported with their 
individual plasma concentrations and individual derived pharmacokinetic parameters; 
however, they will not be included in descriptive statistics for plasma concentrations, 
pharmacokinetic parameters or other statistical assessment.
Only concentration values within the validated concentration range and actual sampling times 
will be used for the calculation of pharmacokinetic parameters. Concentrations used in the 
pharmacokinetic calculations will be in the same format provided in the bioanalytical report, 
(that is, to the same number of decimal places provided in the bioanalytical report).
Plasma concentrations will be plotted graphically versus time for all subjects as listed in the
drug plasma concentration-time tables. For the presentation of the mean profiles, the
arithmetic mean, geometric mean and the planned blood sampling times will be used.
In addition to the analysis described Section 7.3.1, the absolute bioavailability factor F will 
be calculated for each subject on Day 1 as 
F = normalised AUC0-∞ (oral) / normalised AUC0-∞(i.v.)
and for each subject on Day 28 as
F = normalised AUC0-24, 28 (oral) / normalised AUC0-∞, 28 (i.v.).

Handling of missing PK data will be performed according to the relevant SOP of the Sponsor 
(001-MCS-36-472).
For the non-compartmental analysis, concentration data identified with NOS, NOR or NOA 
will generally not be considered. Concentration values in the lag phase identified as BLQ will 
be set to zero. All other BLQ values of the profile will be ignored. The lag phase is defined as 
the period between time zero and the first time point with a concentration above the 
quantification limit.
7.5
RANDOMISATION
All subjects will receive the same treatments in one fixed sequence. Therefore, no 
randomisation is necessary in this trial (see also Section 4.1.2). A list of consecutive subject 
numbers will be provided for procedural reasons (see Section 4.1.2).
7.6
DETERMINATION OF SAMPLE SIZE
It is planned to enter a total of at least 10 and most 12 subjects into the trial, because this 
sample size is considered sufficient to achieve the aims of this exploratory trial.

(IEC) and competent authority (CA) according to national and international regulations. The 
same applies for the implementation of changes introduced by amendments.
Prior to a subject’s participation in the trial, written informed consent must be obtained from 
each subject (or the subject’s legally accepted representative) according to ICH GCP and to 
the regulatory and legal requirements of the participating country. Each signature must be 
personally dated by each signatory and the informed consent and any additional subject 
information form are to be retained by the investigator as part of the trial records. A copy of 
the signed and dated written informed consent and any additional subject information must be 
given to each subject or the subject’s legally accepted representative.
The subject must be informed that his personal trial-related data will be used by Boehringer 
Ingelheim in accordance with the local data protection law. The level of disclosure must also 
be explained to the subject.
The subject must be informed that his medical record may be examined by authorised 
monitors (Clinical Monitor Local/Clinical Research Associate) or Clinical Quality Assurance 
auditors appointed by Boehringer Ingelheim, by appropriate IRB/IEC members, and by 
inspectors from regulatory authorities.
