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, 
smoking status and alcohol history), relevant medical history, concomitant therapy and review of inclusion/exclusion 
criteria.
2.
Pharmacokinetics (PK): BI 1467335 and metabolites in plasma; [14C]-radioactivity in whole blood and plasma. At all 
time points, samples for [14C]-radioactivity in whole blood and plasma will be taken. Samples for PK assessment of cold 
BI 1467335 will be collected up to 10 h 
 
 after intake of radiolabelled drug on Day 1.
 
3.
The time is approximate; the procedure is to be performed within a time window of 3 h prior to drug administration.
4.
At these time point, a sample is taken for measurement of haematocrit.
5.
All stools (for [14C]-radioactivity assessment 
) will be collected quantitatively from Day 1 in 
sampling intervals: 0-24, 24-48, 48-72, 72-96, 96-120, 120-144, 144-168, 168-192, 192-216, 216-240, 240-264, 264-
288, 288-312 and 312-336 hours after intake of [14C]BI 1467335. Thereafter, if warranted, 24 h collections are to be 
performed on days 21-22, 28-29, 35-36, 42-43, and 49-50. A blank sample will be collected before drug administration 
on Day 1. Collection of the predose faeces sample will start from approximately -48 h before drug administration. 
Faeces sampling for [14C]-radioactivity assessment will be stopped when the release criteria for radioactivity recovery 
(Section 3.1) have been met (earliest stopping on day 15). “┼” means end of last collection interval, start of following 
collection interval. All samples: planned for determination of [14C]-radioactivity. For technical reasons, the planned 
times used in the CRF and result transfer files will have 5 minutes added to the planned times in the Flow Chart (i.e. 
0:05-24:04, 24:05-48:05, …)
6.
Urine collection intervals (for PK/[14C]-radioactivity assessment 
 (planned time): on Day -1 or 
Day 1 predose (blank) sample, on Day 1 prior to start of urine collection voiding of the bladder, 0-4, 4-8, 8-12, 12-24, 
24-48, 48-72, 72-96, 96-120, 120-144, 144-168, 168-192, 192-216, 216-240, 240-264, 264-288, 288-312, and 
312-336 hours after drug administration. Thereafter, if warranted, 24 h collections are to be performed on days 21-22, 
28-29, 35-36, 42-43, and 49-50. Urine sampling for PK will be stopped when release criteria for radioactivity recovery
(Section 3.1) have been met (earliest stopping on day 15). “┼” means end of last collection interval, start of following 
collection interval. All samples: planned for determination of [14C]-radioactivity, BI 1467335 
 
7.
If several actions are indicated at the same time point, the intake of meals will be the last action.

8.
End-of-trial (EOT) examination to be performed within 1 to 7 days after last discharge from the study centre, or, if all 
once-weekly 24 h sampling periods are needed, prior to discharge on Day 50. EOT examination includes physical 
examination, vital signs, ECG, safety laboratory, recording of AEs and concomitant therapies.
9.
Subjects are to be fasted for at least 10 h before sample is taken.
10. Blood sampling for an individual subject can be stopped if [14C]-radioactivity in plasma is below limit of detection 
(<LLOQ 10 dpm/mL) at two consecutive sampling time points for this subject.
11. The planned times for admission, discharge, start and end of the urine and faeces collection intervals are approximate. 
The procedures are to be performed within a time window of +/- 4 h to the planned time. 
12. Subjects are to collect faeces at home within 24 h intervals before admission to once-weekly in-house collection 
intervals. Home collection intervals: Day 20-21, 27-28, 34-35, 41-42, and 48-49. If faeces are collected in the 
subsequent in-house collection interval, faeces collected at home will be discarded. If no faeces is collected in the 
subsequent in-house collection interval (no defecation), faeces collected at home will be used instead for analysis.
13. For definition of the individual subject’s end of trial see Section 6.2.3
14. Urine drug and alcohol screening will be done at this time point.
16. Subjects will collect a predose faeces sample at home in specific containers provided by

warranted 24 h collections are to be performed on days 49-50, 56-57, 63-64, 70-71 and 77-78. A blank sample will be 
collected before drug administration on Day 1. Collection of the predose faeces sample will start from approximately
-48 h before drug administration. Faeces sampling for [14C]-radioactivity assessment will be stopped when the release 
criteria (Section 3.1) for radioactivity recovery (Section 3.1) have been met (earliest stopping on day 43). “┼” means end 
of last collection interval, start of following collection interval. All samples: planned for determination of [14C]-
radioactivity. For technical reasons, the planned times used in the CRF and result transfer files will have 5 minutes added 
to the planned times in the Flow Chart (i.e. 0:05-24:04, 24:05-48:05, …).
6.
Urine collection intervals (for PK/[14C]-radioactivity assessment 
; planned time):. A predose 
urine sample collected on Day -1 or Day 1 predose will serve blank sample. Before dosing of labelled compound on Day 
28, subjects should be asked to void bladder. Urine collection starts -648:00-652:00,652:00-656:00, 656:00-660:00, 
660:00-672:00, 672-696:00, 696:00-720:00, 720:00-744:00, 744:00–768:00, 768:00- 792:00, 792:00-816:00, 816:00–

1008:00. Thereafter, if warranted 24 h collections are to be performed on days 49-50, 56-57, 63-64, 70-71 and 77-78.
Urine sampling will be stopped when release criteria for radioactivity recovery (Section 3.1) have been met (earliest 
stopping on day 43). “┼” means end of last collection interval, start of following collection interval. All samples: 
planned for determination of [14C]-radioactivity. Samples of the collection interval on Day 28/29 planned for analysis of 
BI 1467335 
 
7.
If several actions are indicated at the same time point, the intake of meals will be the last action.
8.
End-of-trial (EOT) examination to be performed within 1 to 7 days after last discharge from the study centre, or, if all 
once-weekly 24 h sampling periods are needed, prior to discharge on Day 78. EOT examination includes physical 
examination, vital signs, ECG, safety laboratory, recording of AEs and concomitant therapies.
9.
Subjects are to be fasted for at least 10 h before sample is taken.
10. Beginning at time point 684:00 only samples for analysis of [14C]-radioactivity in whole blood and plasma to be taken. 
Blood sampling for an individual subject can be stopped at 816:00h or later if [14C]-radioactivity in plasma is below 
limit of detection (<LLOQ 10 dpm/mL) at two consecutive sampling time points for this subject.
11. The planned times for admission, discharge, start and end of the urine and faeces collection intervals are approximate. 
The procedures are to be performed within a time window of +/- 4 h to the planned time. 
12. Subjects are to collect faeces at home within 24 h intervals before admission to once-weekly in-house collection 
intervals. Home collection intervals: Day 48-49,. Day 55-56, Day 62-63, Day 69-70, and Day 76-77. If faeces are 
collected in the subsequent in-house collection interval, faeces collected at home will be discarded. If no faeces is 
collected in the subsequent in-house collection interval (no defecation), faeces collected at home will be used instead for 
analysis.
13. For definition of the individual subject’s end of trial see Section 6.2.3
14. Urine drug and alcohol screening will be done at this time point.
15. Treatment will be stopped from Day 35 onwards if [14C]-radioactivity in plasma is below limit of detection 
(LLOQ 10 dpm/mL) for this subject.
17. Subjects will collect a predose faeces sample at home in specific containers provided by 
18. On specific study days (Day 3 to Day 6, Day 8 to Day 13, Day 15 to Day 20 and Day 22 to 27) intake of study 
medication under ambulatory conditions.

INTRODUCTION
1.1
MEDICAL BACKGROUND
Boehringer Ingelheim (BI) is developing BI 1467335 (formerly Pharmaxis PXS-4728A), an 
oral, small-molecule inhibitor of semi-carbazide-sensitive amine oxidase (SSAO), also 
known as vascular adhesion protein-1 (VAP-1) or amine oxidase copper-containing 3 
(AOC3), in the indication of non-alcoholic steatohepatitis (NASH).
NASH is characterised histologically by a high level of steatosis, ballooning of hepatocytes, 
and necroinflammation. NASH often leads to fibrosis which can progress to cirrhosis with a 
high risk of liver failure. 
 
 
 
 
 
 
 
 
With a prevalence of about 20 - 30% in the general population of Western countries, non-
alcoholic fatty liver disease (NAFLD) is rapidly becoming the most common liver disease 
worldwide [R15-5365]. While simple hepatic steatosis can have a benign, non-progressive 
course, about 40% of patients with NAFLD progress to NASH. As the disease progresses, 
significant fibrosis develops in 37 - 41% of subjects within 15 years. In the United States, 
NASH is believed to be the most common cause of liver cirrhosis [R15-6070] which is 
estimated to be the 12th leading cause of death [R15-6057]. Patients with NASH are also at 
increased risk of hepatocellular carcinoma, even in the absence of cirrhosis [R15-5365]. By 
2023, about 13 million patients are projected to have NASH with advanced stages (i.e. ≥ 
stage 3) of fibrosis (of those, 2.9 million in the US, 3.5 million in EU, 5 million in China). 
Individuals with advanced fibrosis are estimated to progress with a 4% annual event rate to 
cirrhosis. The risk of liver-related death in Western patients with NASH ranges from 10% 
over 13.7 years to 18% over 18.5 years [P13-02280].
To date, no approved therapy for liver fibrosis or effective disease modifying regimen for 
NASH is available, despite the strong interface with metabolic syndrome, obesity and Type 2 
diabetes mellitus. The current standard of care for NASH is weight loss through diet and 
exercise to improve insulin resistance and lower fat mass which is a clinically challenging 
goal to achieve and shows minimal impact on disease progression [R15-6044].
1.2
DRUG PROFILE
BI 1467335 is a small molecule AOC3 inhibitor that exhibits both anti-inflammatory and 
anti-fibrotic characteristics in various animal models. AOC3 is a membrane bound adhesion 
protein that facilitates the binding of leukocytes to endothelial cells and the subsequent

RATIONALE, OBJECTIVES, AND BENEFIT - RISK 
ASSESSMENT
2.1
RATIONALE FOR PERFORMING THE TRIAL
This trial is intended to examine the metabolism in humans, the mass-balance of excretion,
plasma and urinary concentrations of BI 1467335
 
 
 Major tasks involve the structure elucidation of metabolites as 
well as the [ C]-radioactivity in blood cells, plasma, urine and faeces. This study will also 
help to determine the metabolic pathways following oral administration of [14C]BI 1467335
in healthy volunteers.
The data are necessary for in-depth understanding of the pharmacokinetics of BI 1467335
including quantitative determination of elimination pathways and drug metabolites and are 
required for submission to regulatory authorities.
2.2
TRIAL OBJECTIVES
The main objective of this trial is to investigate the basic pharmacokinetics of BI 1467335, its 
metabolites, [14C]-radioactivity, including mass balance, excretion pathways and metabolism 
following a single oral dose of 10 mg [14C]BI 1467335 on Day 1 or on Day 28 during
multiple dose treatment (Day 1 to Day 27 then Days 29 to last day of treatment) as 
determined by radioactivity collection with q.d. administration of non-labelled 10 mg 
BI 1467335 given to healthy male volunteers.
Primary objective is:

To assess the mass balance recovery from excreta (urine and faeces) of 
[14C]BI 1467335
Secondary objective is:

To assess the Cmax and AUC0-tz for total radioactivity after single dose and after 
repeated doses and Cmax and AUC0-tz of BI 1467335 in plasma after single dose.

To assess the Cmax,ss and AUC0-for BI 1467335 in plasma after repeated doses.

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.
Procedure-related risks
The use of an indwelling venous catheter for the purpose of blood sampling may be 
accompanied by mild bruising and also, in rare cases, by transient inflammation of the wall of 
the vein. In addition, in rare cases a nerve might be injured while inserting the venous 
catheter, potentially resulting in paresthesia, reduced sensibility, and/or pain for an indefinite 
period. The same risks apply to veinipuncture for blood sampling.
The total volume of blood withdrawn during the entire study per subject will not exceed the 
volume of a normal blood donation (500 mL). No health-related risk to healthy subjects is 
expected from this blood withdrawal.
Drug-related risks and safety measures
On target effects
BI 1467335 could cause on-target toxicity as its anti-inflammatory effects may reduce the 
immune response and thus worsen infections. However, a deleterious effect relating to a 
reduction in leukocyte or lymphocyte migration was not seen in any of the preclinical models.
This also true for two completed phase I studies in healthy male and female subjects 
 
 Nonetheless, clinical and laboratory signs of 
reduced immune response will be monitored throughout the study.

Drug-induced liver injury (DILI)
Although rare, a potential for drug-induced liver injury (DILI) is under constant surveillance 
by sponsors and regulators. Therefore, this study requires timely detection, evaluation, and
follow-up of alterations in selected liver laboratory parameters to ensure subjects´ safety.
Administration of 14C-marked BI 1467335
[14C]BI 1467335 is labelled with the isotope [14C] which is necessary for the purposes of this 
mass balance trial. Therefore, subjects will be exposed to ionizing radiation. The effective 
dose that each subject receives from one administration of 2 MBq is approximately 0.56 mSv
(see Appendix 10.1). For biomedical investigations in small groups of healthy volunteers, an 
effective dose ≤ 1.0 mSv is considered acceptable.
Summary of benefit-risk assessment
In a previous trial in healthy subjects, multiple oral doses of 
 
BI 1467335 administered once daily over 28 days were safe and well-tolerated. In the current 
trial, either single or multiple oral doses of 10 mg of BI 1467335 will be administered to 
healthy male volunteers. Each participating subject will receive only one radioactive dose.
The trial design is optimized to collect as much relevant information as possible on the 
pharmacokinetics of BI 1467335 without exposing participating volunteers to undue risk. 
However, there is always the potential of serious adverse events (SAEs) occurring with intake 
of trial medication. Risks to subjects will be minimized and addressed by eligibility criteria, 
safety laboratory examinations, ECG and vital sign measurements, in-house observation 
periods and verbal communication concerning AEs. 
If the investigator should have any clinical concern, the safety of the subjects will be of 
paramount importance. The investigator has the discretion to remove subjects from the study 
should there be any safety concerns or if the subject’s wellbeing is at jeopardy.

The risk associated with the expected maximal radiation burden falls in ICRP category IIa 
with minor level risk. This is considered to be acceptable.
The results of this trial are necessary for development of BI 1467335. Successful 
development of BI 1467335 is expected to provide a new valuable treatment for patients with 
NASH.
The risks of the participating volunteers are minimized and justified when compared to the 
potential benefits of this trial.

DESCRIPTION OF DESIGN AND TRIAL POPULATION
3.1
OVERALL TRIAL DESIGN AND PLAN
The study will be performed as an open-label, single-arm and single- or multiple dose trial in 
healthy male subjects in order to investigate the basic pharmacokinetics of BI 1467335, 
 
and [14C]-radioactivity, including mass balance  
 
 following a single oral dose of [14C]BI 1467335. For subjects assigned to the 
multiple dose treatment, the single oral dose of [14C]BI 1467335 is dosed following multiple 
dosing of cold drug (Days 1-27 and 29-last dose given based on radioactive recovery, 
maximum Day 40).
The planned radioactive dose per subject is 2.0 MBq (54 µCi). 
For the single dose part Day 1 is the day of [14C] labelled drug administration. Subjects will 
stay in the study centre up to the morning of day 15 for the collection of samples of blood, 
urine, and faeces. Subjects will be readmitted to the study centre for 24 h collection intervals 
of urine and faeces on days 21, 28, 35, 42, and 49, if release criteria have not been met. 
Within 24 h before each of these once-weekly in-house collection intervals, subjects are to 
collect faeces at home. This 24 h interval home collection faeces will be used for analysis in 
case no defecation occurs in the subsequent 24 h in-house collection interval.
For the multiple dose part Day 28 is the day of [14C] labelled drug administration. Non-
labelled compound will be administered at site or at home during Day 1 to Day 27 and from 
Day 29 to Day 40 (dosing may be stopped before Day 40 if release criteria based on 
[14C]-radioactivity have been reached for individual subjects, see below). From the evening 
of Day 27 to the morning of Day 43 subjects will remain in the study centre for the entire 
duration. Subjects will be released from the centre on Day 43. Subjects will then be 
readmitted to the study centre for 24 h collection intervals of urine and faeces on days 49, 56, 
63, 70, and 77, if release criteria have not been met. Within 24 h before each of these once-
weekly in-house collection intervals, subjects are to collect faeces at home. This 24 h interval 
home collection faeces will be used for analysis in case no defecation occurs in the 
subsequent 24 h in-house collection interval.
Single dose and multiple dose part will be conducted in different subjects. The study is 
planned to start with the multiple dose part, while the single dose part will be scheduled close 
to Day 28 of the multiple dose part.
For determination of whether release criteria have been reached for individual subjects, 
[14C]-radioactivity will be measured in excreta (urine and faeces). The actual recovery results 
will be reported as a percentage of the administered dose. 
If one of the following release criteria is true (i.e., release criteria have been met), 
24 h collection intervals after day 15 (single dose) or Day 43 (multiple dose) will not be 
performed / will be stopped:

-
Greater than or equal to 90% of the administered dose has been recovered in urine and 
faeces combined over the investigational period, or
-
If <1% of the dose administered has been collected in urine and faeces within 2 
separate, consecutive 24 h intervals, and
-
Concentration of total radioactivity in plasma <5% of Cmax of total radioactivity in 
plasma
In the event that excretion release criteria are met after Day 15 (single dose) or Day 43 
(multiple dose), but the mass balance recovery is less than 90%, subjects will still be asked to 
return to the clinic for 24 hour collection of urine and faeces on Days 21, 28, 35, 42, and 49 
(single dose) or on Days 49, 56, 63, 70 and 77 (multiple dose) or until the recovery is deemed 
to be sufficient for mass balance purposes. If a subject is unable to attend one of these visits, 
they may be allowed to reschedule the visit if needed.”
Irrespective of whether release criteria have been met or not after collection interval Day 
49-50 (single dose) or Day 77-78 (multiple dose), no further collections are planned.
An overview of all relevant trial activities is provided in the Flow Chart. For visit schedule

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 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
This is a standard design for a [14C]-human study for investigation of absorption, distribution, 
metabolism, and excretion including determination of mass balance. Inclusion of a control 
groups is not required for this investigation. Despite of rapid elimination of radioactivity in 
rat ADME trials (Section 1.2), it cannot be excluded that prolonged sampling is still 
necessary in humans. Therefore, following 14 days in-house excreta collection after 
radioactive dosing (Treatment Group 1 on Day 1, Treatment Group 2 on Day 28 following a 
preceding treatment of unlabeled compound from Day 1 to Day 27), subjects will return on a 
weekly basis for in-house 24 h collection intervals for up to 7 weeks after last dosing as long 
as release criteria are not met (Section 3.1).
Blinding is not necessary, because all subjects receive the same dose per treatment group.
3.3
SELECTION OF TRIAL POPULATION
It is planned that 16 healthy male subjects will enter the study. 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 basic pharmacokinetics of BI 1467335
 
 including absorption, metabolism, and elimination 
and quantitative determination of excretion by mass balance. 
 
 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. 
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 were given
investigational drug or not.

Main diagnosis for study entry
The study will be performed in healthy male subjects.
3.3.2
Inclusion criteria
Subjects will only be included into the trial, if they meet the following criteria:
1.
Healthy male 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 tests 
2.
Age of 30 to 65 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.
Subjects who are sexually active must use, with their partner, highly effective 
contraception from the time of administration of trial medication until 4 months after 
administration of trial medication. Adequate methods are:
-
Condoms plus use of hormonal contraception by the female partner that started at 
least 2 months prior to administration of trial medication (e.g., implants, injectables, 
combined oral or vaginal contraceptives, intrauterine device) or
-

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. 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
4. The sponsor decides to discontinue the further development of the investigational 
product.

The investigator / the trial site will be reimbursed for reasonable expenses incurred in case of 
trial termination (except in case of the third reason).
3.3.5
Replacement of subjects
In case some subjects do not complete the trial, the trial clinical monitor together with the 
trial pharmacokineticist and the trial statistician are to decide if and how many subjects will 
be replaced. Replacement of subjects should always be done in mutual agreement with the 
principal investigator. A replacement subject will be assigned a unique study subject number, 
and will be assigned to the same treatment as the subject he or she replaces.

Method of assigning subjects to treatment groups
This is an open-label, 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 are 
-
for the eight planned subjects assigned to the single dose 
treatment and 
-
 in case volunteer replacement is necessary (see Section 3.3.5). If 
assigned to the multiple dose treatment respective subject numbers are 
-
 for the eight 
planned subjects and 
 -
 in case of required volunteer replacement.
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
 
 A dose of 10 mg, administered either as 
single or multiple dose, is considered adequate for the objectives of the current trial. 
The dose on Day 1 (SD) or Day 28 (MD) administered as oral solution will include 2.0 MBq 
(54 µCi) of [14C]-radiolabelled BI 1467335. The radiolabeled dose of 2.0 MBq is required to 
provide sufficient analytical sensitivity to enable metabolite quantification in a sufficiently 
low range. The total effective dose (radiation burden) amounts to 0.56 mSv. This is below the 
limit of 1.0 mSv and considered acceptable. Radiation burden calculations are presented in 
Appendix 10.1. For risk-benefit assessment, see Section 2.3.
4.1.4
Drug assignment and administration of doses for each subject
Subjects assigned to the multiple dose part will receive a preceding treatment of unlabeled 
10 mg BI 1467335 as film-coated tablet once daily from Day 1 to Day 27. Subjects assigned 
to the single dose part receive only one dose on Day 1 of [14C]-radiolabelled 10 mg 
BI 1467335 as oral solution as described below.
In the morning of Day 1 (single dose) or Day 28 (multiple dose), following an overnight fast 
of at least 10 h, all subjects will receive one single oral dose of the radiolabelled trial drug 
([14C]BI 1467335 oral solution 0.5 mg/mL (20 mL; 2.0 MBq)). Treatment with non-
radiolabelled compound (film-coated tablets) will continue from Day 29 up to Day 40, but 
may be stopped earlier in case release criteria have been met (see Section 3.1). 
The radiolabelled medication will be administered to a subject in the sitting position under 
supervision of the investigator or an authorised designee (administration directly out of the 
glass bottle the solution is contained in). Thereafter, the bottle will be rinsed 2 times with

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 (SD) and Day 28 (MD) lunch will be given 4 h postdose. During the first 4 h after 
drug administration (only on Day 1 [SD part] and Day 28 [MD part]), 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 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.

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 above.
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 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.
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.

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.
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. 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.

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.

5.4
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.

5.5.1
Pharmacokinetic endpoints
5.5.1.1
Primary endpoints
Primary endpoints will be the mass balance recoveries of [14C]-radioactivity in urine and 
faeces after single and multiple doses: 

feurine, 0-t2 (fraction of [14C]-radioactivity excreted in urine as percentage of the 
administered oral dose over the time interval from 0 to the last quantifiable time 
point)

fefaeces, 0-t2 (fraction of [14C]-radioactivity excreted in faeces as percentage of the 
administered oral dose over the time interval from 0 to the last quantifiable time 
point)
Timeframe: The timeframe for determination of these endpoints depends on discharge of 
radioactivity from each individual subject and is predicted to vary between 2-7 weeks after 
drug administration.
5.5.1.2
Secondary endpoints
The following secondary endpoints will be evaluated for [14C]-radioactivity: in the single and 
multiple doses treatment groups: 

Cmax (maximum measured concentration of the analyte)

AUC0-tz (area under the concentration-time curve of the analyte over the time interval 
from 0 to the last quantifiable time point)
The following secondary endpoints will be evaluated for BI 1467335 in plasma in the single 
dose treatment group: 

Cmax (maximum measured concentration of the analyte)

AUC0-tz (area under the concentration-time curve of the analyte over the time interval 
from 0 to the last quantifiable time point)
The following secondary endpoints will be evaluated for BI 1467335 in plasma in the 
repeated doses treatment group: 

Cmax,ss (maximum measured concentration of the analyte at steady state)

AUC0-(area under the concentration-time curve of the analyte over the time interval 
from )

5.5.2.2
Sampling of whole blood and plasma for [14C]-radioactivity analysis in whole 
blood and plasma and quantification of BI 1467335
 
in plasma
Single dose
At each time point listed in the Flow Chart, 8 mL blood will be taken from a forearm vein 
using a commercial vacutainer or monovette collection tube with K2-EDTA as anticoagulant.
Withdrawal of blood will be done via an indwelling cannula.
Multiple dose
From Day 1 up to and including Day 21, 3 mL, from Day 28 each time point listed in the 
Flow Chart, 6 mL (for time points pre-dose – 12 h (inclusive) or 8 mL (for time points 
24 h - 36 h) or 4 mL (for time points 48 h – last) blood will be taken from a forearm vein 
using a commercial vacutainer or monovette collection tube with K2-EDTA as anticoagulant.
It is planned that from Day 28 all aliquots of all time points are prepared for determination of 
[14C]-radioactivity in whole blood and plasma.
Withdrawal of blood will be done via an indwelling cannula.
Single dose
Aliquots for bioanalysis of BI 1467335
 in 
plasma are planned to be prepared as long as PK blood sample are collected for total 
radioactivity after 336 h.
Multiple dose
Aliquots for bioanalysis of BI 1467335
 in 
plasma are planned to be prepared for up to 24 h after last drug administration, and at predose 
on days specified in the Flow Chart in order to assess steady state on through plasma 
concentrations.
Premature stopping of blood sampling
In case [14C]-radioactivity in plasma samples is not detectable (<LLOQ 10 dpm/mL) at two 
consecutive time points for a subject, blood sampling can be stopped for this subject. 
However, all samples until and including the 336 h sample for single dose and until 24 h for 
multiple dose have to be taken.
Laboratory manual

Urine sampling
During the trial urine will be collected at time points or in intervals as indicated in the Flow 
Chart:

to determine [14C]-radioactivity concentrations in urine

to determine concentrations of BI 1467335 
 
 in urine
A blank sample will be taken prior to drug administration.
For urine collection, the weight of the empty containers has to be determined prior to and at 
the end of the collection interval. The urine 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. The exact start and end times of the urine collection intervals will be recorded in
the CRF.
All samples after intake of [14C]BI 1467335 are planned to be used for determination of 
[14C]-radioactivity.
Single dose:
Samples until and including the collection interval 312-336 h are planned to be used for 
analysis of BI 1467335

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 (SD and MD) and on Day 28 (MD) 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.
The planned times for admission, discharge, start and end of the urine and faeces collection 
intervals are approximate. The procedures are to be performed within a time window of 
+/- 4 h to the planned time. 
If scheduled in the Flow Chart at the same time as a meal, 12-lead ECG recordings, vital 
signs, blood samplings, and urine/faeces collection 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 and urine/faeces 
sampling times/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 parameters. If beginning or end of a urine/faeces collection 
interval and a blood sample are scheduled for the same time point, urine/faeces collection 
should be done first, with withdrawal of the blood sample as closely to the planned time point 
as possible.
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.

6.2.2
Treatment period
Each subject assigned to the SD group will receive a single dose of [14C]BI 1467335 on 
Day 1. Each subject assigned to the MD group will receive a single dose of BI 1467335 from 
Day 1 up to Day 27 and from day 29 up to Day 40 and a single dose of [14C]BI 1467335 on 
Day 28.
On Day -1 (SD) or Day 27 (MD) 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 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 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 basic pharmacokinetics of BI 1467335, 
 [14C]-radioactivity, including mass balance, 
 following a single oral dose of 10 mg [14C]BI 1467335 
given to healthy male subjects.
7.1.2
Endpoints
Primary endpoints are pharmacokinetic endpoints as listed in Section 5. Safety and 
tolerability will be determined on the basis of the parameters listed in Section 5.2.
7.1.3
Model
No statistical model will be used.
7.2
NULL AND ALTERNATIVE HYPOTHESES
No confirmatory analysis will be conducted for this study. Data will be reported with 
descriptive statistics only.
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
The primary and secondary parameters (refer to Section 5.5.1) will be calculated according to 
the relevant corporate procedure of the sponsor ‘Standards and processes for analyses 
performed within Clinical Pharmacokinetics/Pharmacodynamics’ (001-MCS-36-472, current 
version). Analyses will be performed for parent drug  
 and for total radioactivity.
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, which will be decided no later than in the Report Planning 
Meeting.

Relevant protocol violations may be 
•
Study drug not administered or wrong drug administered
•
Administered dose (amount of drug) is not in compliance with the protocol, i.e. is 
too low or too high
The PK analysis set (PKS) includes all subjects in the treated set who provide at least one 
primary or secondary PK endpoint value not excluded according to the description above. 
Thus, a subject will be included in the PKS, even if he/she contributes only one PK endpoint 
value for one period to the statistical assessment.
Excluded subjects will be listed with their individual plasma, blood, urine and faeces 
concentrations and individual pharmacokinetic parameters, however, will not be included in 
descriptive statistics for concentrations, pharmacokinetic parameters or other statistical 
assessment.
The primary analysis of primary and secondary endpoints will be based on descriptive 
statistics only using PKS. Descriptive analyses will be described in more detail in the TSAP.
7.3.2
Secondary analyses
Refer to Section 7.3.3 for a description of the analysis of safety.
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’.
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 treatment. 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 and post-study intervals).
Adverse events will be coded using the Medical Dictionary for Regulatory Activities
(MedDRA). Frequency, severity and causal relationship of AEs will be tabulated by 
treatment, system organ class and preferred term. SAEs, AESIs (see Section 5.2.2.1) and 
other significant AEs (according to ICH E3) will be listed separately.
Laboratory data will be compared to their reference ranges. Values outside the reference 
range as well as values defined as clinically relevant will be highlighted in the listings. 
Additionally, differences from baseline will be evaluated.

For vital signs, the differences from baseline will be evaluated.
Relevant ECG findings will be reported as AEs
More details will be described in TSAP.
7.3.4
Interim analyses
No interim analysis is planned.
7.3.5
Pharmacokinetic analyses
 
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 plasma/urine 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).
If a predose concentration value is greater than 5% of Cmax, the subject’s pharmacokinetic 
data will be not included in any statistical evaluations, in accordance with international 
guidances. The individual pharmacokinetic parameters of such a subject will be calculated 
and listed separately. If a predose concentration is above BLQ, but less than or equal to 5% of 
the subject’s Cmax value, the subject’s data without any adjustments will be included in all 
pharmacokinetic measurements and calculations.
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 profiles
Handling of missing PK data will be performed according to the relevant Corporate 
Procedure of the Sponsor (001-MCS-36-472).
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).

7.4.3
Pharmacokinetic parameters
Handling of missing PK data will be performed according to the relevant SOP of the Sponsor 
(001-MCS-36-472).
Drug 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
Randomisation is not applicable in this open-label single arm study. All subjects will receive 
the same treatment. A list of consecutive subject numbers for SD and MD subjects separately 
will be provided (see Section 4.1.2 for details of allocation of subject numbers to subjects).
7.6
DETERMINATION OF SAMPLE SIZE
For this exploratory study, no prospective calculations of statistical precision or power have 
been made. The planned sample size of 8 subjects per treatment group has been selected for 
practical reasons and is judged as being adequate to get reliable results regarding the trial 
objectives.

Number of global amendment
1
Rationale for change
Minor inconsistencies in the methods of PK 
sampling required a protocol revision. 
To avoid false positive drug screens during the 
treatment period, the restrictions were amended to 
include a restriction on poppy-seed containing 
products.
