Criteria for
pharmacokinetics:
Secondary endpoints:
After the first dose:
AUC0-24 and Cmax
After the last dose:
AUC0-24,28 and Cmax,28
Further PK parameters of interest will be calculated as appropriate
Criteria for 
pharmacodynamics:
 
Criteria for safety:
Primary endpoint to assess safety and tolerability of BI 1467335 is the number 
[N (%)] of subjects with drug-related adverse events (AEs).
 
 
Statistical methods:
Descriptive statistics will be calculated for all endpoints.
Dose proportionality of BI 1467335 will be explored using a regression model. A 
95% confidence interval (CI) for the slope will be computed.
Linearity index will be estimated using a linear model providing a two-sided 95% CI, 
if AUC0-∞is possible to determine and steady state is achieved.

1.
Screening includes subject information, informed consent, physical examination, check of vital signs, ECG, safety 
laboratory (including drug screening), demographics (including determination of body height and weight, smoking status 
and alcohol history), relevant medical history, concomitant therapy and review of inclusion/exclusion criteria.
2.
The time is approximate; the respective procedure is to be performed and completed within 2 h prior to drug 
administration. Allocation to treatment may be performed at any time following enrolment but must be completed prior 
to (first) drug administration.
3.
If several actions are indicated at the same time point, the intake of meals will be the last action.
4.
End of trial examination includes physical examination, body weight, vital signs, ECG, safety laboratory, recording of 
AEs and concomitant therapies. Confirmation of fitness includes physical examination.
5.
Urine drug screening and alcohol breath test as well as pregnancy test in women will be done at this time point.
6.
AEs and concomitant therapies will be recorded throughout the trial, but will be specifically asked for at the time points 
indicated in the Flow Chart above.
7.
Safety laboratory, ECG, blood pressure assessment and AE questioning to be done and medically evaluated within 
3 days prior to first administration of study drug; this visit can be omitted, if the screening examination is performed on 
Days -3, -2 or -1.
8.
The ECG recording has to be performed as triple on Day 1 and Day 2, Day 14 and Day 15, Day 21, Day 28 and Day 29.
All other ECG recordings will be single ECGs.
9.
Sampling times and periods may be adapted based on information obtained during the trial (e.g. preliminary PK data) 
including addition of samples and visits as long as the total blood volume taken does not exceed 510 mL per subject.

DESCRIPTION OF DESIGN AND TRIAL POPULATION
3.1
OVERALL TRIAL DESIGN AND PLAN
This multiple-rising dose trial is designed as double-blind, randomised, and placebo-
controlled within parallel dose groups.
A total of 36 healthy male and female subjects is planned to participate in the trial, according 
to at least 3 sequential groups comprising 12 subjects per group. However, additional subjects 
may be entered to allow testing of intermediate doses within the approved dose range on the 
basis of experience gained during trial conduct (as described in Section 2.3), i.e. the actual 
number of subjects entered may exceed 36 but no more than 48. Such changes may be 
implemented via non-substantial CTP Amendments.
Within each dose group, 9 subjects will receive the active drug and 3 will receive placebo. 
Only one dose is tested within each dose group.
The dose groups to be evaluated are outlined in Table 3.1: 1 below.

The dose groups will be investigated consecutively in ascending order of doses, maintaining a 
time interval of at least 14 days between last dosing of the previous dose group and the first 
drug administration of the subsequent dose group. The decision to proceed to the next cohort 
at the same dose level or the next higher dose group will be based upon the safety, tolerability 
and PK of the preceding cohort or dose groups as described in Section 2.3, Section 3.1 and in 
Section 3.3.4.1. The inclusion of the second cohort of the 10 mg dose group will be based 
exclusively on safety and tolerability including checking for individual stopping rules (see 
Section 3.3.4.1), but not on PK data.
A documented Safety Review must take place prior to inclusion of any new cohort and 
between dose groups. Furthermore, an unscheduled safety review meeting can be requested 
anytime for any reasonable cause by the Principal Investigator (or an authorised deputy) or 
the sponsor of the study, e.g. because of any unforeseen adverse events, etc. Dose escalation 
will only be permitted if no safety concerns exist in the opinion of the Principal Investigator

(or an authorised deputy) and the trial clinical monitor (or an authorised deputy) as described 
in Section 2.3.
The minimum data set for review consists of the following data:

AEs in the current and, if applicable, preceding dose groups (including clinically 
relevant findings from ancillary safety testing listed below) (Note: AEs may be 
ongoing at the time of Safety Reviews and AE information may be subject to change 
prior to Database Lock)

Results from 12-lead EGG in the current and preceding dose groups.

Vital signs in the current and preceding dose groups

Clinical laboratory tests in the current and preceding dose groups

Check of criteria for stopping subject treatment as per Section 3.3.4.1

PK data including extrapolation to support conclusions about safety margins (not 
required for inclusion of second cohort of the 10 mg dose group since based on the 
results from the previous SRD/MRD study (see Section 1.2.5) exposure is not 
expected to exceed Cmax and 1/2 of the AUC of the 4-week rat toxicology study at 
NOAEL.
The decision to continue with the next cohort at the same dose level or the next higher dose 
level will be made jointly by the Principal Investigator (or an authorised deputy) and the trial 
clinical monitor (or an authorised deputy) based on the criteria described in Section 2.3. 
In-depth analysis includes preliminary PK data, if possible extrapolations of exposure for the 
current and any new cohorts, all available safety data, especially SAEs (if occurred), AEs 
fulfilling stopping criteria, other AEs and out-of-range laboratory results (if considered 
clinically significant) and ECG results. Safety Reviews can be conducted face-to-face or by 
video/telephone conference. The trial clinical monitor is responsible for organizing and 
minuting the reviews. Minutes will be signed off by the Principal Investigator (or an 
authorised deputy) and filed in the ISF and TMF.
To proceed to the next higher dose level at least data up to Day 28 from 10 evaluable subjects 
of the preceding dose level (with at least 7 subjects on active treatment) are required. 
The investigator (after consultation with the sponsor) is allowed to alter the scheduled dose
levels within the planned dose range on the basis of experience gained during the study.
An overview of all relevant trial activities is provided in the Flow Chart. For visit schedules 
and details of trial procedures at selected visits, refer to Sections 6.1 and 6.2, respectively.

3.2
DISCUSSION OF TRIAL DESIGN, INCLUDING THE CHOICE OF 
CONTROL GROUP
For multiple-rising dose trials, the design described in Section 3.1 is viewed favourable under 
the provision not to expose the subjects involved to undue risks since the main study 
objective is to investigate safety and tolerability of BI 1467335.
With the rising dose design, double -blind conditions regarding the subject’s treatment (active 
or placebo) are maintained within each dose group. However, the current dose level will be 
known to subjects and investigators. The disadvantage of this trial design is a possible 
observer bias with regard to the dose-depending effects as well as time effects, but it has the 
virtue of minimizing subject risk by sequentially studying ascending doses. As time-effects 
are expected to be small relative to the differences between the doses in the broad range 
investigated, unbiased comparisons between treatments can still be expected.

It is standard in trials involving healthy volunteers to include a placebo group as control for 
the evaluation of safety, tolerability and pharmacodynamic effects. Each dose group consists 
of 12 subjects with 9 on active treatment, and 3 on placebo. The placebo control group 
includes all subjects of all dose groups treated with placebo. At the 10 mg dose level there 
will be a staggered inclusion of 2 cohorts of 6 subjects. At any higher dose level there will be 
a staggered inclusion of 3 cohorts each consisting of 4 subjects with 3 subjects randomized to 
active treatment and 1 subject randomized to placebo. The criteria to proceed with any new 
cohort are provided in Section 2.3 and Section 3.1.
3.3
SELECTION OF TRIAL POPULATION
It is planned that 36 healthy male and female subjects will enter the study. The actual number 
of subjects entered may exceed the total of 36 if intermediate doses will be tested (see Section 
3.1). Subjects will be recruited from the volunteers' pool of the trial site.
Only male subjects and postmenopausal or surgically sterilised female subjects will be 
included into the study because hitherto no data on reproductive toxicology are available.
A log of all subjects enrolled into the trial (i.e. having given informed consent) will be 
maintained in the ISF at the investigational site irrespective of whether they have been treated 
with investigational drug or not.
3.3.1
Main diagnosis for study entry
The study will be performed in healthy subjects.
3.3.2
Inclusion criteria
Subjects will only be included into the trial, if they meet the following criteria:
1. Healthy male or female subjects according to the investigator’s assessment, based on a 
complete medical history including a physical examination, vital signs (BP, PR), 12-lead 
ECG, and clinical laboratory 
2. Age of 18 to 50 years (incl.)
3. BMI of 18.5 to 29.9 kg/m2 (incl.)
4. Signed and dated written informed consent prior to admission to the study in accordance 
with GCP and local legislation
5. Male subjects, or female subjects who meet any of the following criteria starting from at 
least 30 days before the first administration of trial medication and until 30 days after trial 
completion:
-
Surgically sterilised (including hysterectomy)
-

9. Neutropenia will lead to individual discontinuation from trial medication if any of the 
following applies: 
- Febrile Neutropenia at any time, i.e. absolute neutrophil count (ANC) below lower limit 
of normal with concomitant body temperature greater or equal 38 degrees C
- ANC below 1000/microliter at any time
- ANC below 1500/microliter (but greater 1000/microliter) if still present after 1 week
10. Leukopenia will lead to individual discontinuation from trial medication if any of the 
following applies:
- Febrile leukopenia at any time, i.e. absolute lymphocyte count (ALC) below lower limit 
of normal with concomitant body temperature greater or equal 38 degrees C 
- ALC below 2500/microliter at any time
- ALC below 3000/microliter (but greater 2500/microliter) if still present after 1 week
11. Thrombocytopenia will lead to individual discontinuation from trial medication if any of 
the following applies:
- Thrombocytopenia, i.e. absolute platelet count (APC) below lower limit of normal at 
any time if associated with clinical signs or symptoms of bleeding
- APC below 80,000/microliter at any time
- APC below 100,000/microliter (but greater 80,000/microliter) if still present after 
1 week
In addition to these criteria, the physician may discontinue subjects at any time based on his 
or her clinical judgment.
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.
If it is known that a subject becomes pregnant during the trial, administration of the trial 
medication has to be stopped immediately, and the subject has to be removed from the trial. 
The subject is to be followed until she has given birth or until the end of pregnancy. The 
subject’s data are to be collected until the end of the trial (last visit of last subject) and 
reported in the clinical trial report. For reporting of pregnancy and all related events refer to 
Section 5.2.2.2.

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 more than 50% 
of the subjects show drug-related and clinically relevant adverse events of moderate or 
severe intensity, or if at least one drug-related serious adverse event is reported that is
considered to be unacceptable.
2. The expected enrolment goals overall or at a particular trial site 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.
4. The sponsor decides to discontinue the further development of the investigational 
product.
5. Inclusion of any new cohort, and the treatment of current cohorts will be stopped as soon 
as at least 2 subjects at one dose level on active drug showed relevant individual QT 
prolongation, i.e. a QTc increase of greater 60 ms from baseline in connection with 
absolute QT or QTc greater than 500 ms, which has been confirmed by a repeat ECG 
recording.
6. Inclusion of any new cohort, and the treatment of current cohorts will be stopped as soon 
as at least 2 subjects at one dose level on active drug shows AEs fulfilling stopping 
criteria (Section 3.1).
7. This multiple dose study is planned not to exceed the Cmax or 1/10th of the AUC observed 
at NOAEL in the 4-week rat toxicity study as stated in Section 1.2.3. For this reason 
preliminary PK assessments will be performed at each dose level before starting with the 
next cohort (not applicable at the 10 mg dose level).
The investigator / the trial site will be reimbursed for reasonable expenses incurred in case of
trial termination (except in case of the third reason).

4.1.2
Method of assigning subjects to treatment groups
Prior to the screening visit, subjects will be contacted in writing and informed about the 
planned visit dates. The subjects willing to participate will be recruited to dose groups 
according to their temporal availability. As soon as enough subjects have been allocated to 
the first dose group, the following subjects will be allocated to the next dose level. Therefore, 
the allocation of subjects to dose cohorts is not influenced by trial personnel, but only by the 
subjects’ temporal availability. As the study includes healthy subjects from a homogenous 
population, relevant imbalances between the dose groups are not expected.
The list of subject and medication numbers will be provided to the trial site in advance. The
allocation of subjects to study subject numbers will be performed prior to the first 
administration of trial medication. For this purpose, the subjects will be allocated to a study 
subject number by the method ‘first come-first served’. Once a subject number has been 
assigned, it cannot be reassigned to any other subject.
The randomisation procedure is described in Section 7.5.
4.1.3
Selection of doses in the trial
The doses selected for this trial cover the subtherapeutic as well as the estimated therapeutic 
range and include a safety margin (see Section 1.2).
4.1.4
Drug assignment and administration of doses for each subject
The treatments to be evaluated are outlined in Table 4.1.4: 1 below. The number of dose 
volume for placebo corresponds to the number of dose volume of the respective dose level.

instruction given in Appendix 10.1 by pharmacists or qualified pharmacy staff members or 
qualified medical study personnel at the trial site under the responsibility of the investigator.
The trial medication will be administered to the subjects, while in a sitting position, as an oral 
dose together with about 240 mL of water under supervision of the investigating physician or 
an authorised designee. The so-called four-eye principle (two-person rule) should be applied 
for administration of trial medication and – if applicable – its preparation (e.g. reconstitution),

if correct dosage cannot be ensured otherwise. Administration will be performed following an 
overnight fast, which is to start no later than 10 h before the scheduled dosing.
To ensure a dosing interval of 24 h, the administration of trial medication should take place at 
the same time every day.
Subjects will be kept under close medical surveillance from the evening of Day -1 to the 
morning of Day 4, from the evening of Day 13 to the morning of Day 17, and from the 
evening of Day 27 to the morning of Day 29. During the first 2 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 except for medical examination), or to sleep. For restrictions 
with regard to diet see Section 4.2.2.2.
4.1.5
Blinding and procedures for unblinding
4.1.5.1
Blinding
The trial is designed double-blind with regard to the subjects and the investigators (as well as 
the research staff at the trial site) in order to eliminate observer or performance bias. This 
means avoiding systematic differences in assessments regarding the subject’s treatment 
(active or placebo). According to the rising dose design, the current dose level will be known 
to subjects and investigators.
At the trial site, access to the randomisation schedule is restricted to unblinded pharmacists. 
Access to the codes will be controlled and documented by a signed confidentiality statement, 
which will be stored in the TMF. Persons directly involved in the clinical conduct of the trial 
will not have access to the treatment allocation prior to database lock.
At the ECG laboratory all staff will be blinded with respect to treatment. Within the ECG 
laboratory, the staff involved with interval measurements and assessments will also be 
blinded with regard to the recording date and time as well as time points of the ECGs. Semi-
automatic interval measurements for a given subject will be performed in random and blinded 
sequence by a single technician.
In addition, the trial bioanalyst, will receive the randomisation codes prior to official 
unblinding to perform the interim / preliminary PK analysis. He or she will confirm in writing 
that the codes will be treated confidentially.
In addition, the drug metabolism scientist will receive the randomisation codes prior to 
official unblinding to perform metabolites in safety testing analysis (MIST). He or she will 
confirm in writing that the codes will be treated confidentially.
Regarding the sponsor, the database of this trial will be handled open-label, meaning that the 
trial functions of the sponsor are unblinded (including clinical monitor, data manager, 
statistician, bioanalyst, pharmacokineticist, pharmacometrician, drug metabolism scientist, 
clinical research associate as well as dedicated CRO personnel). The objective of the trial is
not expected to be affected.

4.1.5.2
Procedures for emergency unblinding
For blinded trials, the investigator will be supplied with a set of sealed envelopes containing 
the medication codes for each subject according to the randomisation scheme. The envelopes 
will be kept unopened at the trial site until the end of data collection. An envelope may only 
be opened in emergency situations when the identity of the trial drug must be known to the 
investigator in order to provide appropriate medical treatment or to assure safety of trial 
participants. If the envelope for a subject is opened, the sponsor must be informed 
immediately. The reason for opening the code break must be documented on the envelope or 
appropriate CRF page along with the date and the initials of the person who broke the code. 
At the close-out visit all envelopes are collected.
4.1.6
Packaging, labelling, and re-supply
Drug supplies will be provided by the Department of Pharmaceutical Development of 
Boehringer Ingelheim Pharma GmbH & Co. KG, Biberach, Germany.
The clinical trial supply consists of containers holding the trial medication which are labelled 
with trial identification. The required information according to the German Drug Law as well 
as Annex 13/EU GMP Guideline will be provided on the containers. Smaller boxes and 
bottles within the clinical trial supply containers will be labelled with:

BI trial number

Name of product and strengths or identification code

Pharmaceutical dosage form, quantity of dosage units 

Route and mode of administration

Term ‘For Clinical Trial Use’ (domestic language)

Sponsor name and address

Storage conditions

Use-by date

Subject or medication number

Batch number
The telephone number of the sponsor and name, address and telephone number of the trial 
site are given 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. 
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
The investigator / pharmacist / investigational drug storage manager will receive the 
investigational drugs delivered by the sponsor when the following requirements are fulfilled:

Approval of the study protocol by the IRB / ethics committee

Availability of a signed and dated clinical trial contract between the sponsor and the 
Head of Trial Centre

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 or immediately imminent 
signing of the clinical trial protocol 
Only authorised personnel as documented in the form ‘Site Delegation Log’ may dispense 
medication to trial subjects. The trial medication must be administered in the manner 
specified in the CTP. All unused medication will be disposed locally by the trial site upon 
written authorization by the clinical monitor. Receipt, usage and disposal must be 
documented on the respective forms. Account must be given for any discrepancies.
The investigator / pharmacist / investigational drug storage manager must maintain records of 
the product’s delivery to the trial site, the inventory at the site, the use by each subject, and 
the return to the sponsor or alternative disposal of unused products.
These records will include dates, quantities, batch / serial numbers, expiry (‘use-by’) dates, 
and the unique code numbers assigned to the investigational products and trial subjects. The 
investigator / pharmacist / investigational drug storage manager will maintain records that 
document adequately that the subjects were provided the doses specified by the CTP, and that 
reconcile all investigational products received from the sponsor. At the time of disposal, the 
investigator / pharmacist / investigational drug storage manager must verify that no remaining 
supplies are in the investigator’s possession.

CONCOMITANT THERAPY, RESTRICTIONS, AND RESCUE 
TREATMENT
4.2.1
Rescue medication, emergency procedures, and additional treatments
There are no specific rescue drugs foreseen for the treatment of AEs. No special emergency 
procedures are to be followed. No additional treatment is planned. However, in case of 
adverse events in need of treatment, the investigator can authorise symptomatic therapy. In 
those cases, subjects will be treated as necessary and, if required, kept under supervision at 
the trial site or transferred to a hospital until all medical evaluation results have returned to an 
acceptable level.

intake fluid intake is not allowed except from the 240 mL water administered with the drug 
intake. From breakfast until 22 hours post-dose water intake will be within 1000 to 3000 mL.
Alcoholic beverages, grapefruits, Seville oranges (sour or bitter oranges) and their juices, and
dietary supplements and products including St. John's wort (Hypericum perforatum) are not
permitted starting 7 days before the first administration of trial medication until after the last
PK sample is collected.
 nicotine-containing 
products (e.g., cigarettes, cigars, chewing tobacco, snuff) should be stopped at least 6 weeks 
before screening and abstained from using these products until study completion.
Methylxanthine-containing drinks or foods (such as coffee, tea, cola, energy drinks, and
chocolate) are not allowed at days of inhouse confinement. On the ambulatory days, it is
restricted up to max 200 ml (coffee, tea, cola, red bull, energy drinks), or 50 g (chocolate and
chocolate products).
Excessive physical activity (such as competitive sport) should be avoided starting 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 center under 
supervision of the investigating physician or a designee. The measured plasma concentrations 
and urinary excretion 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).

Assessment of efficacy
Not applicable.
5.2
SAFETY
5.2.1
Endpoints of safety

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.
Adverse reaction
An adverse reaction is defined as a response to a medicinal product which is noxious and 
unintended. Response in this context means that a causal relationship between a medicinal 
product and an adverse event is at least a reasonable possibility. Adverse reactions may arise 
from use of the product within or outside the terms of the marketing authorisation or from 
occupational exposure. Conditions of use outside the marketing authorization include off-
label use, overdose, misuse, abuse and medication errors.

Serious adverse event
A serious adverse event (SAE) is defined as any AE which:

results in death, 

is life-threatening, this 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 prolongation of existing hospitalisation,

results in persistent or significant disability or incapacity, 

is a congenital anomaly/birth defect, 
or 

is to be 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.
Medical and scientific judgement should be exercised in deciding whether other situations 
should be considered serious reactions, such as important medical events that might not be 
immediately life threatening or result in death or hospitalisation but might jeopardise the 
patient or might require intervention to prevent one of the other outcomes listed above. 
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. Any suspected transmission via a medicinal product of 
an infectious agent is also considered a serious adverse reaction.
AEs considered ‘Always Serious’
Cancers of new histology and exacerbations of existing cancer must be reported as a serious 
event regardless of the duration between discontinuation of the drug and the occurrence of the 
cancer.
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 given 
above.
The latest list of ‘Always Serious AEs’ can be found in the RDC system. A copy of the latest 
list of ‘Always Serious AEs’ will be provided upon request. 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. AESI 
need to be reported to the sponsor’s Pharmacovigilance Department within the same 
timeframe that applies to SAE, please see above.
The following are considered as AESIs in this trial:

Hepatic injury, as 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
marked peak aminotransferase (ALT, and/or AST) elevations ≥10 fold ULN
These lab findings constitute a hepatic injury alert and the patients 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.
AESIs are also those AEs fulfilling individual stopping rules as described in Section 3.3.4.1.
Intensity of AEs
The intensity 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
The definition of an adverse reaction implies at least a reasonable possibility of a causal 
relationship between a suspected medicinal product and an adverse event. An adverse 
reaction, in contrast to an adverse event, is characterised by the fact that a causal relationship 
between a medicinal product and an occurrence is suspected.
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 drug treatment continues or remains 
unchanged.
5.2.2.2
Adverse event collection and reporting
AEs 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 through the residual effect period (REP), 
until 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 relevant SAEs and relevant AESIs of which he may 
become aware of.
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 at this early stage of development. 
Therefore, all AEs reported until the trial termination date 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 of 
awareness) to the sponsor’s unique entry point (country specific contact details will be 
provided in the ISF). This immediate report is required irrespective of whether the 
investigational product has been administered or not and irrespective of causal relationship. 
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 
CRF 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 on the 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 trial inclusion they will be considered as 
baseline conditions.
All (S)AEs, including those persisting after individual subject’s end of trial must be followed 
up until they have resolved, have been sufficiently characterised, or no further information 
can be obtained.
Pregnancy
In rare cases pregnancy may occur in a clinical trial. Once a patient has been enrolled into 
this clinical trial and has taken trial medication, the Investigator must report immediately 
(within 24 hours) a potential drug exposure during pregnancy (DEDP) to the sponsor’s 
unique entry point (country-specific contact details will be provided in the ISF). The 
Pregnancy Monitoring Form for Clinical Trials (Part A) should be used.
The outcome of the pregnancy associated with the drug exposure during pregnancy must be 
followed up and reported to the sponsor’s unique entry point on the Pregnancy Monitoring 
Form for Clinical Trials (Part B).
The ISF will contain the Pregnancy Monitoring Form for Clinical Trials (Part A and B).
As pregnancy itself is not to be reported as an AE, in the absence of an accompanying SAE 
and/or AESI, only the Pregnancy Monitoring Form for Clinical Trials and not the SAE form 
is to be completed. If there is an SAE and/or AESI associated with the pregnancy an SAE 
form must be completed in addition.
5.2.3
Assessment of safety laboratory parameters
For the assessment of laboratory parameters, blood 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. Overnight fasting is not required at the discretion of the investigator or designee
for retests.
The parameters that will be determined are listed in Tables 5.2.3: 1 and 5.2.3: 2. Reference 
ranges will be provided in the ISF, Section 10. 
Manual differential white blood cell count or urine sediment examinations will only be 
performed if there is a clinically relevant abnormality in the automatic blood cell count or in 
the urinalysis, respectively.

Electrocardiogram
5.2.4.1
12-lead resting ECG
Twelve-lead resting ECGs (I, II, III, aVR, aVL, aVF, V1 - V6) will be recorded using a 
computerised electrocardiograph (CardioSoft EKG System, GE Medical Systems, Freiburg, 
Germany) at the time points given in the Flow Chart. Electrode placement will be performed 
according to the method of Wilson, and modified Goldberger and Einthoven (Mason-Likar). 
The same electrode positions on a specific subject should be used for all ECG recordings 
throughout the study.
Triple ECGs (recorded within 180 sec) will be recorded on all time points on Day 1, Day 2, 
Day 14, Day 15, Day 21, Day 28 and Day 29. On all other visits/time points single ECGs will 
be obtained. ECGs may be repeated for quality reasons (like alternating current artefacts, 
muscle movements, electrode dislocation). For time points with triple ECGs, all three single 
ECGs will be repeated.
In order to achieve a stable heart rate at rest and to assure high quality recordings at 
comparable resting phases, all ECGs will be recorded for 10-sec duration after the subjects 
have rested for at least 5 min in a supine position. The site personnel will be instructed to 
assure a relaxed and quiet environment so that all subjects are at complete rest during the 
recordings. 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 locally printed ECGs will be evaluated by the investigator or a designee. Additional 
(unscheduled) ECGs may be collected by the investigator for safety reasons. These ECGs are 
assigned to the prior scheduled time point. Unscheduled ECGs will not be included into the 
statistical analysis of interval lengths.
For the inclusion or exclusion (see Section 3.3) of a subject and for the assessment of cardiac 
safety during the study, the QT and QTcB values generated by the ECG machines or their 
manual corrections by the investigators will be used. In doubtful cases, ECGs may be sent 
upfront for centralized evaluation (see below). In this case, these centrally measured results 
would overrule any other results obtained.
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.
All recorded ECGs will be sent electronically to an independent ECG core lab. The
centralised evaluation of all 12-lead ECGs recorded on Day 1 to Day 4, Day 7, Day 14 to

Day 17, Day 21, and Day 28 to Day 29 will be performed by an independent ECG laboratory. 
In case it is needed ECGs recorded at other visits/time points may also undergo centralized 
evaluation.
For this analysis, all cardiac intervals (PR, QRS, RR and and QT intervals) will be 
determined semi-automatically, whereas PR and QRS intervals are determined by a validated 
GE 12-SL-algorithm or equivalent. Other parameters (e.g. cardiac axis) are determined by a 
validated GE 12-SL-algorithm or equivalent but do not undergo semiautomatic evaluation. 
All interval measurements for each subject will be performed on the same lead. The intervals 
will be measured from four cardiac cycles (beats) in lead II. If lead II shows a flat T wave or 
is not measurable for any reason, lead V5 will be used, or if that lead is not measurable, then 
lead I will be used. The lead actually used will be reported in the CTR.
For blinding status see Section 4.1.5.1. No more than two different blinded readers will 
evaluate all ECGs of the study. For quality assurance and control of the measurements, all 
ECGs of a subject will be subsequently reviewed by the ECG technician supervisor or his/her 
designee with respect to the overall variance of the measured intervals, in order to detect 
accidentally switching of leads and/or false subject assignments of the ECGs. After the 
quality control the fiducial point markings will be reviewed by the cardiologist assigned to 
the study. Abnormalities detected during centralized ECG evaluation will not necessarily 
qualify as AE.
The results of the centralized evaluation will be sent from the ECG core lab to the data 
management of BI according to a pre-specified data transmission agreement.
Assessed ECGs will comply with the ICH E14 guidance document and supplements [R05-
2311, R13-0801, R13-4095] as well as the FDA requirements for annotated digital ECGs 
[R09-4830].
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) will be measured by a 
blood pressure monitor (Dinamap, 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
and after ECG recording was taken. 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 with determination of weight.

APPROPRIATENESS OF MEASUREMENTS
All measurements performed during this trial are standard measurements and will be 
performed in order to monitor subjects’ safety and to determine pharmacokinetic and 
pharmacodynamic parameters in an appropriate way. The scheduled measurements will allow 
monitoring of changes in vital signs, standard laboratory values, and ECG parameters that 
might occur as a result of administration of trial medication. The safety assessments are 
standard, are accepted for evaluation of safety and tolerability of an orally administered drug, 
and are widely used in clinical trials. The pharmacokinetic parameters and measurements 
outlined in Section 5.5 are generally used assessments of drug exposure. The biomarker 
measurements outlined in Section 5.6 are of exploratory nature only.
5.5
DRUG CONCENTRATION MEASUREMENTS AND 
PHARMACOKINETICS
Date and clock time of drug administration and exact time points of blood sampling will be 
documented in the CRFs by the medical personnel. The actual sampling times will be used 
for determination of pharmacokinetic parameters.
PK sampling times and periods may be adapted during the trial based on information 
obtained during trial conduct (e.g. preliminary PK data) including addition of samples and 
visits as long as the total blood volume taken per subject does not exceed 510 mL. Such 
changes would be implemented via non-substantial CTP Amendments.

5.5.2
Methods of sample collection
5.5.2.1
Plasma sampling for pharmacokinetic analysis
For quantification of BI 1467335 plasma concentrations, approx. 2.7 mL of blood will be 
taken from an antecubital or forearm vein into a K3-EDTA (tripotassium 
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 venipuncture with a metal needle.
30 µL phenelzine solution (approx. 50 mM/L) will be added to all blood samples before
withdrawal. All blood samples will be centrifuged using a cooled centrifuge at about 2000 x g 
to 4000 x g and at a temperature of 4 - 8°C for at least 10 minutes (intermittent storage on 
ice). The obtained K3-EDTA plasma will be split into two cryotubes (e.g. Nunc tubes) which 
will be frozen immediately and not later than 60 min after blood sampling with interim 
storage on ice. One of the aliquots should contain at least 0.7 mL plasma. The second aliquot 
containing 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.
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.
5.5.2.2
Plasma sampling for drug metabolism analysis
Additional K3-EDTA plasma samples for the identification of drug metabolites will be 
investigated in all dose groups. The blood samples will be drawn in parallel to the PK

samples on Day 28 to 29 (see Flow Chart). At each of these time points, 2.7 ml blood will be 
needed for metabolite analysis. The blood samples will be centrifuged using a cooled 
centrifuge at about 2000 x g to 4000 x g and at a temperature of 4 - 8°C for at least 10 
minutes (intermittent storage on ice). The obtained K3-EDTA plasma (approximately 1 mL) 
will be transferred into a single polypropylene tube. Samples will be stored at about -70°C or 
below until transfer to the metabolism laboratory.
At a minimum, the sample tube labels should list the following information: BI trial number, 
subject number, visit, planned sampling time and ‘MetID’. Further information such as 
matrix and analyte may also be provided. 
Metabolite analysis will be performed under non-GxP conditions in the laboratory of 
Boehringer Ingelheim Pharma GmbH & Co. KG
Drug Metabolism and Pharmacokinetics
Birkendorfer Straße 65
88397 Biberach/Riß, Germany
Only data related to the parent compound and its metabolites will be acquired. Evaluation of 
the drug metabolism will be reported separately but not included in the CTR of this trial. The 
study samples will be discarded after completion of the experiments but not later than 3 years 
after the final study report has been signed.
5.5.2.3
Urine sampling for pharmacokinetic analysis
A blank urine sample will be collected before administration of trial medication (within 2 h 
before drug dosing) and two 0.5 mL aliquots will be retained to check for analytical 
interference by concomitant or rescue medication.
All urine voided during the sampling intervals indicated in the Flow Chart will be collected in 
2 L polyethylene (PE) containers and stored at room temperature. Subjects will be told to 
empty their bladders at the end of each sampling interval.
The urine weight/volume (weight will be set equal to volume, i.e. 1 kg = 1 L, without 
correction for specific gravity of urine) for each collection interval will be documented and 
two 2 mL aliquots (e.g. Nunc tubes) will be stored for bioanalytical measurement. The weight 
of the empty container will be determined and the weight of the container at the end of each 
sampling interval will be determined.
Until transfer to the analytical laboratory, the urine samples will be stored at about -20C or 
below at the clinical site and stored at the analytical laboratory at –20C or below until 
analysis. The back-up aliquots will be transferred to the analytical laboratory after the 
bioanalyst has acknowledged safe arrival of the first aliquot.
After completion of the trial the urine samples may be used for further methodological 
investigations, e.g. for stability testing, assessment of metabolites. However, only data related 
to the analyte and/or its metabolite(s) will be generated by these additional investigations. 
The study samples will be discarded after completion of the additional investigations but not 
later than 5 years upon the final study report has been signed.

5.5.2.4
Additional blood sample for stability-testing
In order to assess the stability of the analyte in whole blood, one additional blood sample 
each on days 1, 14 and 28 will be taken from all subjects of dose group 10 mg and 15 mg.
Approximately 3.6 mL blood will be taken from an antecubital or forearm vein using three 
1.2 mL K3 EDTA-blood drawing tubes at the time indicated in the Flow Chart (immediately 
after the drawing of a regular blood PK sample, which is to say that no additional venous 
puncture will be necessary).
To the first two 1.2 mL K3 EDTA-blood drawing tubes 10µL phenelzine solution (approx. 
50 mM/L) will be added before taken from all subjects of dose group 1 and 2 at the time 
indicated in the Flow Chart.
Approx. 0.5 mL of plasma will be generated out of each blood sample:

Sample handling for stability samples of dose group 2, procedures will be provided in 
a separate lab manual.Blood sample one (‘stability reference’) will be centrifuged 
within 10 min after collection. Centrifugation will last for about 10 min (at about 2000 
g to 4000 g and 4 to 8 °C), plasma will be separated and transferred into a freezer.

Blood sample two and three (‘stability test’) will be stored for about 4 h at room 
temperature and ambient light conditions (documentation of storage time necessary) 
and will then be centrifuged and stored according to the first sample. To the plasma 
sample from blood sample three 5µL phenelzine solution (approx. 50 mM/L) will be 
added before freezing.
At a minimum, the aliquots should be labelled with the following information: BI trial 
number, administered drug, subject number, planned sampling time, ‘stability reference’ or 
‘stability test’.
Until transfer to the analytical laboratory, all aliquots will be stored at about -20 °C or below 
at the clinical site. All aliquots will be provided to the responsible bioanalyst together with 
the information about sample handling (i.e. storage time of ‘test sample’ at room 
temperature). After receipt, the aliquots will be stored at the bioanalytical laboratory at about 
-20°C or below until analysis.
The results of the analysis of these samples will not be reported within this clinical trial but 
will be used for bioanalytical assay validation and therefore included in the corresponding 
method validation report. The remaining sample volume will be discarded upon completion 
of the method validation report at the latest.

INVESTIGATIONAL PLAN
6.1
VISIT SCHEDULE
Exact times of measurements outside the permitted time windows will be documented. The 
acceptable time windows for screening and end of trial examination are given in the Flow 
Chart.
Study measurements and assessments scheduled to occur ‘before’ trial medication 
administration on Day 1, Day 14, and Day 28 are to be performed and completed within a 
2 h-period prior to the trial drug administration (including blank values for PK and 
biomarkers collected predose on Day 1).
The acceptable deviation from the scheduled time for vital signs, ECG and laboratory tests 
will be ± 30 min for the first 4 h after trial drug administration and ± 30 min thereafter when 
not already stated otherwise in the flowchart.
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 venipuncture are scheduled for the same time, venipuncture should be the last of 
the measurements due to its inconvenience to the subject and possible influence on 
physiological parameters.
For planned individual plasma concentration sampling times and urine collection intervals 
refer to the Flow Chart. While these nominal times should be adhered to as closely as 
possible, the actual sampling times will be recorded and used for determination of 
pharmacokinetic parameter.
If a subject misses an appointment, it will be rescheduled if possible. The relevance of 
measurements outside the permitted time windows will be assessed no later than at the 
Blinded Report Planning Meeting.
6.2
DETAILS OF TRIAL PROCEDURES AT SELECTED VISITS
6.2.1
Screening
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.
Before first dosing on day 1 pharmacogenomic genotyping will be performed in all subjects 
(for details see Section 5.3).
6.2.2
Treatment period
Each subject will receive a single dose of BI 1467335 or placebo from Day 1 to Day 28.
Study participants will be admitted to the trial site in the evening of day -1 and kept under 
close medical surveillance for at least 24 h following the first /last drug administration. The

subjects will be kept hospitalized from the evening of Day -1 to the morning of Day 4, the 
evening of Day 13 to the morning Day 17 and from the evening of Day 27 to the morning of 
Day 29.On all other time periods the study will be performed in an ambulatory fashion
provided there are no medical reasons preventing the discharge from the unit.
For details on time points and procedures for collection of plasma and urine 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 and follow-up 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. Adverse events persisting after trial completion must be 
monitored until they have normalised or have been sufficiently characterised. 
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 safety and tolerability of BI 1467335
by using descriptive statistics for all endpoints comparing active dose groups to placebo. The 
primary endpoint is defined in Section 5.2.1. Inferential statistics is not planned (as explained 
in Section 7.2).
The secondary objective is the exploration of the pharmacokinetics (PK) 
) of BI 1467335. Endpoints as specified in 5.5.1 and 5.7.1 will be 
analysed by descriptive statistics. Secondary endpoints as defined in Section 5.5.1.1 will be 
subjected to analysis of dose proportionality by use of the power model. 
 
 
 
 
7.2
NULL AND ALTERNATIVE HYPOTHESES
Safety and tolerability of 3 different dose groups of BI 1467335 are to be determined on the 
basis of the investigated parameters in comparison to placebo. It is not planned to test any 
statistical hypotheses with regard to these variables in a confirmatory sense. Instead, they will 
be described in their entirety and evaluated by descriptive statistical methods.
Confidence intervals will be computed and will have to be interpreted in the perspective of 
the exploratory character of the study, i.e. confidence intervals are considered as interval 
estimates for effects.
7.3
PLANNED ANALYSES
Adherence to the protocol (such as inclusion/exclusion criteria, times of measurement, 
compliance with intake of trial medication, treatment dispensing errors, prohibited 
concomitant medication, completeness and consistency of data) will be checked. Important 
protocol violations (IPVs) will be identified no later than in the Report Planning Meeting and 
provided in the TSAP.
7.3.1
Primary analyses
All treated subjects (that is, all subjects who received at least one dose of study drug), will be 
included in the treated set.
The primary endpoint will be analysed only descriptively on the treated set. For more details 
see Section 7.3.3.

The secondary endpoints (refer to Section 5.5.1) will be calculated according to the BI 
Standard Operating Procedure (SOP) ‘Standards and processes for analyses performed within 
Clinical Pharmacokinetics/Pharmacodynamics’ [001-MCS-36-472].
Plasma and urine concentration data and parameters of a subject will be included in the
statistical pharmacokinetic (PK) analyses if they are not flagged for exclusion due to a 
protocol 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 and urine concentrations and/or parameters of a subject will be considered as non-
evaluable, if for example

the subject experienced emesis that occurred at or before two times median tmax of the 
respective treatment (Median tmax is to be determined excluding the subjects 
experiencing emesis),

missing samples/concentration data at important phases of PK disposition curve.
The PK parameter analysis set (PKS) includes all subjects in the Treated Set (TS) who 
provide at least one PK parameter that was not excluded according to the description above.
All statistical evaluations of PK parameters will be based on the PKS.
Excluded subjects will be listed with their individual plasma concentrations and individual 
pharmacokinetic parameters, however, will not be included in descriptive statistics for plasma 
concentrations, pharmacokinetic parameters or other statistical assessment.
Assessment of dose proportionality
Dose proportionality will be assessed using the pharmacokinetic endpoints AUC0-24, Cmax, 
AUC0-24,28 and Cmax,28 as specified in 5.5.1.1.
The basic model for the investigation of dose proportionality will be a power model that 
describes the functional relationship between the dose and PK endpoints.
The model consists of a regression model applied to log-transformed data. The corresponding 
ANCOVA model includes the logarithm of the dose as a covariate.

Together with 
and 
, taking natural logarithms converts this model 
to a linear form as follows:
where
logarithm of the pharmacokinetic endpoint for subject j at dose level i; 
where i = 1, 2, 3, j = 1, 2, …, N;

intercept parameter;
slope parameter;
logarithm of dose i;
random error associated with subject j at dose level i (assumed to be 
independent and identically normally distributed).
This equation can be fit as a linear regression model.
Based on the estimate for slope parameter (β), a 2-sided 95% CI for the slope will be 
computed. Perfect dose proportionality would correspond to a slope of 1. The assumption of a 
linear relationship between the log-transformed pharmacokinetic endpoint and the log-
transformed dose will be checked.
If dose proportionality over the entire dose range investigated cannot be shown, an attempt 
will be made to identify dose range(s), where dose proportionality can be assumed.
When steady state is already reached after 14 days of treatment, dose proportionality will be 
also investigated for AUC0-24,14 and AUC0-24,28 together (Cmax,14 and Cmax,28 respectively) 
using the following model accounting for the repeated measurement per subject:

The AUC, can be AUC,  and/or AUC,! depending on when the steady state is

In order to construct a confidence interval for LI, a statistical model using AUCτ,ss and

7.3.3
Safety analyses
Safety will be assessed for the primary endpoint and parameter of interest listed in Section 
5.2.1. All treated subjects (that is, all subjects who received at least one dose of study drug), 
will be included in the safety evaluation. Safety analyses will be descriptive in nature and will 
be based on BI standards.
Treatments will be compared in a descriptive way. The placebo control group in the safety 
evaluation will consist of all placebo treated subjects, regardless of the dose group in which 
they were treated. The active treatment groups will be compared to the placebo group in a 
descriptive way. Tabulations of frequencies/proportions will be used for the evaluation of 
categorical (qualitative) data, and tabulations of descriptive statistics will be used to analyse 
continuous (quantitative) data.
The analyses will be done by ‘treatment at onset’.
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, and those after the trial termination 
date will be assigned to ‘post-study’. These assignments including the corresponding time 
intervals will be defined in detail in the TSAP.
Adverse events will be coded using the Medical Dictionary for Regulatory Activities 
(MedDRA). Frequency, intensity according to CTCAE grading and causal relationship of 
AEs will be tabulated by treatment, primary 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 will be flagged. Additionally, differences from baseline will be evaluated.
For vital signs, the differences from baseline will be evaluated.

A centralised evaluation of all 12-lead ECGs recordings (see Section 5.2.4) will be the basis 
for the derivation of further ECG parameters based on the ECG variables QT, HR, QTcF, 
QTcB, PR, QRS, and RR. The baseline value of an ECG variable is defined as the mean of 
the triple ECG measurements prior to drug administration. It is planned to evaluate the 
difference to placebo of change from baseline for QTcF, QT and HR over time via a repeated 
measurements model as well as the exposure response relationship of change from baseline 
for QTcF, QT and HR. More details on this and further analysis as well as the derivation of 
the quantitative and qualitative ECG endpoints are given in the TSAP.
7.3.4
Preliminary PK analyses
At least 7 preliminary analyses of plasma PK parameters (Cpre, C1, AUC0-24 and Cmax) are 
planned to be performed to ensure that assessed or extrapolated systemic exposure to 
BI 1467335 will not exceed predefined margins (see Section 2.3). Additional preliminary PK 
analyses may be performed based on the request of the Trial Clinical Monitor, the 
Investigator, or Trial Clinical Pharmacokineticist if deemed necessary based on the results of 
available preliminary PK analyses, tolerability and safety of the compound, or changes of 
dosing schedule (e.g. additional intermediate doses).
1st analysis:
after both cohorts of the first dose group (10 mg) have been treated for 
28 days. All plasma samples collected up to this time point will be analysed, and the data (if 
possible, together with data from a previous multiple rising dose study [c09036683-01]) will 
be used for extrapolation of Cmax and AUC0-24 on days 14 and 28 with higher doses of 
BI 1467335, to support the decision to start with the first cohort of the second dose group 
(planned: 15 mg).
2nd analysis: after the first cohort of the second dose group (15 mg) has been treated for 
7 days. All plasma samples collected up to this time point will be analysed and the data will 
support the decisions to continue with the treatment of the first cohort and to start with 
treatment of second cohort.
3rd analysis: 
after the second cohort of the second dose group (15 mg) has been treated for 
14 days. All plasma samples collected up to this time point will be analysed and the data will 
support the decisions to continue with the treatment of the first and second cohort and to start 
with treatment of the third cohort.
4th analysis:
after all three cohorts of the second dose group (15 mg) have been treated for 
28 days. All plasma samples collected up to this time point will be analysed, and the data 
(together with those from the previous preliminary analyses) will be used for extrapolation of 
Cmax and AUC0-24 on days 1, 14 and 28 with higher doses of BI 1467335, to support the 
decision to start with the first cohort of the third dose group (20 mg).
5th analysis: 
after the first cohort of the third dose group (20 mg) has been treated for 
7 days. All plasma samples collected up to this time point will be analysed and the data will 
support the decisions to continue with the treatment of the first cohort and to start with 
treatment of second cohort.

6th analysis: 
after the second cohort of the third dose group (20 mg) has been treated for 
14 days. All plasma samples collected up to this time point will be analysed and the data will 
support the decisions to continue with the treatment of the first and second cohort and to start 
with treatment of the third cohort.
7th analysis: 
after all three cohorts of the third dose group (20 mg) have been treated for 
28 days. All plasma samples collected up to this time point will be analysed, and data 
(together with those from the previous preliminary analyses) will be used for extrapolation of 
Cmax and AUC0-24 on days 1, 14 and 28 with higher doses of BI 1467335, to support the 
decision whether to include further dose groups into the study.
In contrast to the final PK calculations, the preliminary analyses will be based on planned 
sampling times rather than on actual times. Therefore, minor deviations of preliminary and
final results may occur. The preliminary analyses will provide individual concentration-time 
data and PK parameters (without subject identification) and descriptive statistics thereof.
The preliminary results will be distributed to the Investigator and the trial team. The PK data 
together with safety and tolerability results will be used for decisions to continue with 
treatments as described above. No formal preliminary PK report will be written.
No inferential statistical 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 BI SOP ‘Standards and processes for analyses performed within 
Clinical Pharmacokinetics/Pharmacodynamics’ [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 / urine concentrations and individual pharmacokinetic parameters; 
however, they will not be included in descriptive statistics for, 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).
Descriptive evaluations of PK parameters listed in 5.5.1.2 are based on PKS.
The following descriptive statistics will be calculated for analyte concentrations as well as for
all pharmacokinetic parameters: N, geometric mean, geometric coefficient of variation, 
arithmetic mean, arithmetic coefficient of variation, standard deviation, minimum, median, 
and maximum. The data format for descriptive statistics of concentrations will be identical 
with the data format of the respective concentrations. The descriptive statistics of 
pharmacokinetic 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 three significant digits in the clinical trial 
report.

In addition, the PK data from this study may be included in a population PK analysis at the 
project level. This analysis will not be part of the CTR, but will be reported separately.
7.4
HANDLING OF MISSING DATA
7.4.1
Safety
With respect to safety evaluations, it is not planned to impute missing values.
7.4.2
Plasma/urine drug concentration - time profile
Handling of missing PK data will be performed according to the relevant SOP of the Sponsor 
[001-MCS-36-472].
For tabulation and graphical displays, drug concentration data identified with NOS (no 
sample available), NOR (no valid result), NOA (not analysed), or BLQ (below the lower 
limit of quantification) will be displayed as such and not replaced by zero at any time point 
(this rule also applies also to the lag phase, including the predose values).
For the calculation of PK parameters by 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.
7.4.3
Pharmacokinetic parameters
No imputation of missing PK parameters will be performed.
 
7.5
RANDOMISATION
Subjects will be randomised within each dose group in a 3:1 ratio, which reflects the ratio of 
subjects receiving active drug to placebo.

The sponsor will arrange for the randomisation as well as packaging and labelling of trial 
medication. The randomisation list will be generated using a validated system, which 
involves a pseudo-random number generator and a supplied seed number so that the resulting 
allocation is both reproducible and non-predictable.
The randomisation list will contain additional blocks to allow for subject replacement (refer 
to 3.3.5).
7.6
DETERMINATION OF SAMPLE SIZE
It is planned to include a total of 36 subjects in this trial. The planned sample size is not based 
on a power calculation. The size of 12 subjects per dose group (9 on active treatment, and 3
on placebo) is commonly used in multiple-rising dose studies of the present type and is in 
general considered as sufficient for the exploratory evaluation of multiple dose safety and 
pharmacokinetics [R95-0013].
Additional subjects may be entered to allow testing of additional doses within the planned 
dose range on the basis of experience gained during trial conduct (e.g. preliminary PK data), 
i.e. the actual number of subjects entered may exceed 36.

2 bottle concept, see also Chapter 10.1.4.
10.1.3.1
Reconstitution procedure for the preparation of the active BI 1467335 oral 
solution 0.5 mg/mL
Necessary materials
a)
BI 1467335 Powder for Oral Solution 40 mg (target solution concentration 
BI 1467335: 0.5 mg/mL), provided in 100 mL amber glass bottles with plastic screw 
cap.
b)
Solvent for Oral Solution 80 mL (Sucralose 4 mg/ml + Menthol 2 mg/ml) provided in 
100 mL glass vials with tear-off caps.
Reconstitution procedure
Step 1:
Open the vial containing the Solvent for Oral Solution 80 mL (Sucralose 
4 mg/mL + Menthol 2 mg/ml)
Step 2:
Transfer the content of the Solvent for Oral Solution 80 mL (Sucralose 4 mg/mL 
+ Menthol 2 mg/ml) completely and carefully into the bottle containing the 
BI 1467335 Powder for Oral Solution 40 mg
Step 3:
Close the bottle with the plastic screw cap and shake the bottle manually until the 
BI 1467335 powder is wetted. Mount the bottle in a horizontal recumbent 
position on a mechanical shaker (e.g. Bühler Type KL2) 
Step 4:
Let the bottle shake for 30 min at 350 rpm in its horizontal recumbent position.
Visually control that the powder is dissolved (clear to almost clear solution). 
After dissolution the solution is ready to use 
The final BI 1467335 Oral Solution concentration is 0.5 mg/mL.
The allowable dose range is from 0.1 mg - 40 mg.
lowest possible dose in mg = C1 * V1
highest possible dose in mg = C1 * V2
C1 = oral solution concentration = 0.5 mg/mL 
V1 = 0.2 mL corr. to the minimum volume to be withdrawn from the oral solution 
         (assumption: use of 1 mL syringe)
V2 = 80 mL, corr. to the maximum allowable administration volume per dose

General remarks - important!
Because of lacking analytical coverage beyond the instructed preparation procedure of the 
different dose formulations no further (external) dilutions of the reconstituted solutions are 
allowed!
The present reconstitution instruction does not contain any advice how to withdraw a specific 
dose from the reconstituted solutions. The specific dose volumes to be withdrawn from the 
described dose formulations in order to obtain a required dose will be calculated and 
documented by TransMed in the Clinical Trial Protocol (CTP) and subsequent documents 
(e.g. work sheets)!

of the stability of the analyte in whole blood.
4. Attainment of steady state analysis via 
MMRM model changes to secondary analysis 
and nonlinear mixed model analysis added as 
primary analysis.
Rationale for change
The 10 mg dose group in this ongoing study 
1386.8 has recently completed the 4 week 
treatment period. The evaluation is ongoing, 
preliminary data have become available. Overall, 
BI 1467355 was well tolerated. There were in 
particular no AEs considered to be dose limiting 
and no SAEs, all subjects completed the treatment 
period per protocol. There were no clinically 
relevant abnormalities with respect to safety 
laboratory, vital signs, or ECG. In particular there 
were no ECG findings suggesting adverse effects 
on the QT interval. Preliminary PK data obtained
for the 10 mg dose level shows in all subjects an
AUC exposure below Cmax and 1/10th of the 
AUC at NOAEL in the 1 month rats study, the 
initially defined exposure threshold not to be 
exceeded by subjects. Extrapolations based on the 
clinical PK data derived from the completed 10 
mg dose group and the data obtained with the 
completed 2 week Phase I study suggest that with 
the next planned dose of 15 mg QD over 4 weeks 
some subjects may exceed the 1/10th AUC 
margin at the end of the 4 week treatment period. 
The estimated mean and the 95% prediction 
interval of Cmax extrapolation to 15 mg are still 
well below the Cmax at NOAEL. As steady state 
was not reached after 4 weeks of treatment with 
10 mg BI 1467355 it is considered to be more 
appropriate to use a nonlinear fit for 
determination of the attainment of steady state.
Additional data obtained with the 15 mg dose 
group are considered crucial to provide a safety 
margin regarding the assumed maximum 
efficacious dose of 10 mg QD in NASH patients. 
Since in the completed 10 mg dose group there 
were no safety signals precluding the continuation 
with the next higher dose it is considered to be 
justified to increase the initial exposure threshold 
from 1/10th AUC to ½ AUC at NOAEL obtained 
in the 4 week toxicology study in rats. It should

be highlighted that all remaining stopping rules 
(individual discontinuation criteria or stopping 
rules for the whole study) will remain unchanged. 
In addition the study is conducted under close 
clinical monitoring (including central ECG 
reading) to early identify adverse safety signals.
In context with the changes required for 
Amendment 3 a few remaining inconsistencies 
were also corrected.
