Endpoints
Primary Endpoint: Plasma  AOC3 activity relative to baseline in %, at 
24 h post dose, after 12 weeks of treatment
Secondary endpoints:

number (%) of subjects with adverse reactions

Relative ALT change from baseline after 12 weeks of 
treatment

Relative AST change from baseline after 12 weeks of 
treatment

Relative AP change from baseline after 12 weeks of treatment

Relative -GT change from baseline after 12 weeks of 
treatment

Relative caspase cleaved cytokeratin 18 (M30) change from 
baseline after 12 weeks of treatment

Relative total cytokeratin 18 (M65) change from baseline 
after 12 weeks of treatment
Safety criteria:
Adverse event reporting, vital signs and standard laboratory tests
Statistical methods:
For dose-response relationship analysis a non-linear 3-parametric 
model is used to fit the primary endpoint AOC3 activity relative to
baseline, at 24 h post dose, after 12 weeks of treatment with either BI 
1467335 or placebo. The dose will be estimated where the fitted 
mean curve drops below 10%. The secondary biomarker endpoints
including ALT, AST, AP, -GT, caspase cleaved and total CK18 are 
evaluated using a mixed effect model for repeated measurements 
(MMRM). The estimated dose effects at week 12 will then be 
analysed using the MCPMod approach to test if there is a non-flat 
dose response relationship between the different doses of BI 1467335 
and placebo.

3 At visits 2, 4 and 6, the respective IMP kit number has to be allocated to the patient via IRT. At Visit EOT/ED the IRT call 
is performed to close out the patient (Termination of medication).
 
 
 
 
or 
DNA banking, blood samples will be collected at visit 2 and EOT/ED (for details please refer to section 5.5.4).
6 Also to be completed for patients who are withdrawn or who have discontinued the trial early: in case of early termination,
the EOT/ED Visit will be completed instead of the planned treatment period visit. This early discontinuation (ED)
visit will include the same procedures as the normal EOT visit except PK, PG and PD sampling. Visit FU should be 
performed 28 days after the last study drug intake.
For patients who discontinue IMP but are willing to attend scheduled trial visits, only one PK sample and one PD 
blood sample for measurement of AOC3 activity should be taken and the actual time of the blood draw recorded. 
Please refer to section 6.2.2.
8 PD blood samples for measurement of AOC3 activity and concentration. Please see Flow Charts 2, 3, 4 and table 10.1:1 for 
timing.
For patients who discontinue IMP but are willing to attend scheduled trial visits, only one PD blood sample for 
measurement of AOC3 activity should be taken and the actual time of the blood draw recorded. Please refer to section 
6.2.2.
 
10 Pregnancy Testing: Xs =serum testing; Xu= onsite urine testing; Serum pregnancy is done at screening and as a reflex 
when urine testing is positive.
11 All patients will complete a study drug diary during the treatment phase to document drug intake and treatment 
compliance. The diary will be dispensed to the patients at Visit 2 and regularly checked by site-staff at the following 
visits. Please refer to section 6.2.2
12 12-lead ECGs will be recorded at the visits outlined in the flowchart for all patients approximately 90 min after study drug 
intake. At visits without drug administration ECGs should preferentially be performed prior blood sampling. For 
detailed timing please refer to Flow Charts 2, 3, 4. ECGs will be recorded after the patients have rested for at least 5 
minutes in a supine position. The ECG at the screening visit is regarded as baseline. Please refer to section 5.3.4
13 Confirm eligibility from Screening visit.
14 Only symptom-derived physical examination required.
15 At dosing visits: The respective procedure is to be performed and completed prior to study drug administration.
 
 
17 Waist and hip circumference only at screening and EOT/ED. For detailed instruction how to measure waist and hip
circumference see Section 5.3.1.1.
18 For the timing of this blood sample please refer to table 10.1:1. Not applicable in case of early discontinuation.
 
20If the historic ALT > 1.25 ULN value is older than 3 months prior to screening, the ALT > 1.5xULN  must be confirmed 
via two measurements at least 1 week apart within the screening period. Please refer to sections 3.3.2 and 6.2.1
21Clinical imaging (optional): only applicable for patients who don’t have the required clinical imaging results suggestive of 
NASH yet (no more than 3 years prior to screening, according to Inclusion criterion #1). Not required if histological 
 
23 One additional blood sample (sodium citrate coagulation tube) will be taken for platelet-rich plasma (PRP). Please refer to 
section 5.5.2.

INTRODUCTION
1.
MEDICAL BACKGROUND
1.1
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) and amine oxidase copper-containing 3 (AOC3) for 
the indication non-alcoholic steatohepatitis (NASH).
NASH is characterized histologically by a high level of steatosis, ballooning of hepatocytes, 
and necroinflammation. AOC3 in liver sinusoidal endothelial cells is responsible for the firm 
adhesion and transmigration of leukocytes and for the propagation of the inflammatory 
environment in steatohepatitis. Fibrotic regions of NASH liver sections are strongly positive 
for AOC3 immune reactivity [R15-5697]. The associated generation of peroxide during the 
course of amine oxidation is known to activate quiescent stellate cells supporting the 
differentiation into myofibroblasts and fibrotic tissue generation. Recent findings with AOC3 
knockout mice or animals treated with anti-AOC3 antibody displayed reduced hepatic 
inflammation and fibrosis development in several disease-related models of liver injury [R15 
5365] and are supportive of this therapeutic concept. Therefore, targeting inhibiting AOC3 
enzymatic activity might be beneficial for patients with steatohepatitis and fibrosis in order to 
reduce the recruitment of leukocytes into the liver and reduce cytokine and oxygen stress 
dependent hepatocyte damage and activation of hepatic stellate cells.
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 NASH progress [R16-5301].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 in the US, according to the National Institute 
of Health [R15-6057]. Patients with NASH are also at increased risk of hepatocellular 
carcinoma (HCC), 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 EU5, 5 million in China). 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. 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 therefore only affects a minor proportion of the patients [R15-6044].
Persistent inflammation in response to liver injury is the critical factor that drives progression 
to fibrosis, cirrhosis, and hepatocellular carcinoma [R15-5365]. Inflammation at any site, 
including the liver, is the result of an accumulation of leukocytes organized into an 
inflammatory infiltrate. For this to occur, leukocytes must be recruited from the circulation 
by interactions with the endothelium and positioned within the tissue [R15-6046]. A key 
protein in promoting the recruitment of leukocytes in liver tissue is AOC3, which is 
constitutively expressed on human hepatic endothelium. BI 1467335 is an irreversible AOC3 
inhibitor with anti-inflammatory and anti-oxidative stress activities that is currently under

development for the treatment of chronic liver disease secondary to Non-alcoholic 
Steatohepatitis (NASH). 
DRUG PROFILE
1.2
BI 1467335 is an AOC3 inhibitor that is being developed for symptomatic treatment of 
NASH. In humans, NASH is characterized by steatohepatitis, lipotoxicity, necroinflammation, 
stellate cell differentiation, myofibroblast activation and fibrosis. The potential role of AOC3 
in NASH warrants the development of the irreversible AOC3 inhibitor BI1467335 for the 
treatment of patients with NASH.

RATIONALE, OBJECTIVES, AND BENEFIT - RISK 
2.
ASSESSMENT
RATIONALE FOR PERFORMING THE TRIAL
2.1
Increased plasma levels of ALT in NASH patients are a consequence of the lipotoxicity-
induced necroinflammation of the parenchymal liver tissue. Soluble plasma AOC3 (sAOC3) 
activity is positively correlated with a variety of diseases including atherosclerosis, liver and 
kidney fibrosis, and septic shock, thereby indicating a potential pivotal role in various forms 
of inflammation (R15-5801, R15-5774, R15-5773, R15-5766, R15-5767, P15-12198, R15-
5771, R15-5772, R15-5802). Inhibition of AOC3, therefore, has the potential to reduce 
oxidative stress and hepatic inflammation in steatohepatitis, and to improve fibrosis 
resolution in patients with NASH and ultimately resulting in reduced liver cell damage, 
thereby reducing elevated plasma ALT levels. This first study in NASH patients is performed
to support the proof of mechanism and to allow further insights into the dose-response
relationship of BI 1467335.
TRIAL OBJECTIVES
2.2
The primary objective of this study is the proof of mechanism and support of dose finding, 
together with the safety evaluation in patients with clinical evidence of NASH.
This proof of mechanism study will explore the inhibition of AOC3 activity (% of baseline) 
after 12 weeks treatment as the primary endpoint. 
 
. This will 
include the effect of BI 1467335 on reduction of secondary biomarker endpoints (ALT, AST, 
AP, -GT and CK18 fragments).
Safety will be assessed throughout the study to provide key information regarding the use of
BI 1467335 in patients with NASH. 
The proof of clinical mechanism will be achieved through primary endpoint comparison 
(inhibition of AOC3 activity (% of baseline)) of the four BI 1467335 doses (1mg QD, 3mg 
QD, 6mg QD, 10mg QD) and placebo. To this end, the dose-response relationship of the 
primary endpoint will be analysed by means of non-linear regression. 
For the secondary endpoints ALT, AST, -GT, AP, caspase cleaved cytokeratin 18 and total 
cytokeratin 18 a non-flat dose response relationship between the BI doses and placebo will be 
tested using the multiple comparison procedures and modelling (MCPmod) approach [R10-
1424].

DESCRIPTION OF DESIGN AND TRIAL POPULATION
3.
OVERALL TRIAL DESIGN AND PLAN
3.1
This is a 12-week, multi-centre, randomised, double blind, placebo-controlled, parallel-group 
comparison in patients with NASH. In total, 108 patients who meet the entry criteria are 
planned to be randomised in this trial. All eligible patients will be instructed at every visit 
(including screening) to adhere to their normal dietary and exercise regimen from screening 
until safety follow-up visit (see inclusion criterion #5 for details). Eligible patients will be 
randomised to the 12 week double-blind treatment period at Visit 2 and will be assigned to 
one of the 5 treatment groups (placebo QD, BI 1467335 1 mg QD, BI 1467335 3 mg QD, BI 
1467335 6 mg QD or BI 1467335 10 mg QD; each patient will receive one active treatment 
and/or placebos to match the alternative active treatment). The randomised treatment will be 
double blind. After the end of the double-blind treatment period, patients will be followed up 
for additional 4 weeks without study medication. Safety will be evaluated at each visit until 
end of the observational period which is 28 days after end of treatment or for an appropriately 
longer time in case of unresolved adverse events.

3.1.1
Administrative structure of the trial
The trial is sponsored by Boehringer Ingelheim (BI).
A Coordinating Investigator is responsible to coordinate Investigators at different centres 
participating in this multicentre trial. Tasks and responsibilities are defined in a contract. 
Relevant documentation on the participating (Principal) Investigators and other important 
participants, including their curricula vitae, will be filed in ISF.
Boehringer Ingelheim has appointed a Trial Clinical Monitor, responsible for coordinating all 
required activities, in order to 
-
manage the trial in accordance with applicable regulations and internal SOPs,
-
direct the clinical trial team in the preparation, conduct, and reporting of the trial,
-
ensure appropriate training and information of local clinical monitors (CML), Clinical 
Research Associates (CRAs), and Investigators of participating countries.
The organisation of the trial in the participating countries will be performed by the respective
local or regional BI-organisation (Operating Unit, OPU) in accordance with applicable 
regulations and internal SOPs, or by a Contract Research Organisation (CRO) with which the 
responsibilities and tasks will have been agreed and a written contract filed before initiation 
of the clinical trial.
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

DISCUSSION OF TRIAL DESIGN, INCLUDING THE CHOICE OF 
3.2
CONTROL GROUP(S)
A randomised, double blind, placebo- controlled design is chosen for this trial in order to 
evaluate safety, pharmacodynamics, and PK of BI 1467335 in patients with clinical evidence 
of NASH.
A placebo control arm was chosen to be included in order to evaluate the absolute effects of 
BI 1467335 on safety and tolerability. This is acceptable as no standard treatment is 
available. 
SELECTION OF TRIAL POPULATION
3.3
In total, 108 patients with clinical evidence of NASH will be randomised to one of the five 
treatment arms. Approximately 50 sites in multiple countries are planned. Recruitment will 
be competitive. Patients who discontinue following randomisation will not be replaced and

3.3.4
Removal of patients from therapy or assessments
Removal of individual patients
3.3.4.1
An excessive withdrawal rate can have a severe negative impact on the scientific value of the 
trial. Every effort should be made to keep patients in the trial as scheduled. This includes 
careful patient selection and appropriate explanation of the trial requirements and procedures 
prior to enrolment as well as an explanation of the consequences of premature withdrawal.
An individual patient is to be withdrawn from trial treatment if:

The patient withdraws consent for trial treatment or trial participation, without 
the need to justify the decision.

The patient needs to take concomitant drugs that interfere with the 
investigational product or other trial medication 4.2.2,

The patient can no longer be treated with trial medication for other medical 
reasons (such as surgery, adverse events, other diseases, or pregnancy)

The patient has repeatedly shown to be non-compliant with important trial 
procedures and, in the opinion of both, the investigator and sponsor 
representative, is not willing or able to stick to the trial requirements in the 
future.
3.3.4.1.1
Removal of individual patients in case of increased liver enzymes
In addition, study-specific procedures have been defined in case of increased liver enzymes
(AST, ALT and total bilirubin) after randomisation as outlined below [R16-5309].

Treatment should be temporarily interrupted and the increased laboratory values need to be 
confirmed by a second measurement (i.e. the patient is informed to stop IMP and to come for 
an additional unscheduled visit within 48 hours of initial laboratory hepatic injury alert / 
notification or as soon as possible if timelines cannot be met). Other causes for liver injury 
should be excluded. 
1) If the values are confirmed or even further increased, IMP will be 
permanently stopped and the patient is withdrawn from treatment and 
will be monitored closely on a weekly basis until resolution or stabilization 
in the following cases:
AST is normal at baseline and:

If AST is more than 8x ULN

If AST is 5-8x ULN for more than 2 weeks
ALT and/or AST are abnormal at baseline and:

If ALT or AST is more than 8x baseline OR > 500 U/L absolute value, 
whichever is lower.
After resolution or stabilization the patient is encouraged to continue in the 
study and complete all visits. If the patient is not willing to continue in the 
study, the patient should complete the withdrawal- and follow-up protocol 
study procedures.
2) If the values are confirmed, IMP will stay interrupted and the patient 
will be monitored closely until resolution or stabilization in the following 
cases:
AST is normal at baseline and:

If AST is 3x – 8x ULN AND total bilirubin is > 2 mg/dL

If AST is 3x – 8x ULN OR total bilirubin is > 2 mg/dL 
AND the patient is presenting clinical symptoms of hepatic injury as e.g. 
encephalopathy, nausea, vomiting, pruritus, severe fatigue, etc.
ALT and AST are abnormal at baseline and:

If ALT or AST is 5x – 8x baseline OR > 300 U/L absolute value (whichever is 
lower)
AND total bilirubin is > 2 mg/dL 

If ALT or AST is 5x – 8x baseline OR > 300 U/L absolute value (whichever is 
lower) OR total bilirubin is > 2 mg/dL 
AND the patient is presenting clinical symptoms of hepatic injury as e.g. 
encephalopathy, nausea, vomiting, pruritus, severe fatigue, etc.
If the values return to the baseline value (Visit 2), a re-start of the IMP 
can be considered after discussion with the sponsor. After re-start of 
IMP the patient should be monitored on a weekly basis until EOT. In 
the case the initially elevated liver enzyme, which lead to interruption,

increases again more than 2x baseline, the IMP has to be discontinued 
permanently.
Given the patient’s agreement, the patient will continue the study, or 
otherwise should be encouraged to undergo the procedures for early 
treatment discontinuation and follow up as outlined in the Flow Chart (FC)
and section 6.2.3.
3.3.4.1.2
Further criteria for removal of individual patients
If a patient becomes pregnant during the trial, the study medication needs to be discontinued, 
and the patient will complete EOT- and Follow-up Visit procedures. The patient will be 
followed up until birth or otherwise termination of the pregnancy.
If a patient develops QTc > 500 ms during the trial, the study medication needs to be 
discontinued, and the patient will complete EOT- and Follow-up Visit procedures.
For all patients the reason for withdrawal (e.g. adverse events) must be recorded in the CRF. 
These data will be included in the trial database and reported.
Patients who discontinue the trial after receiving the first dose of study medication at visit 2
will not be replaced.
Discontinuation of the trial by the sponsor
3.3.4.2
Boehringer Ingelheim reserves the right to discontinue the trial overall or at a particular trial 
site at any time for the following reasons:
1. Failure to meet expected enrolment goals overall or at a particular trial site
2. Emergence of any efficacy/safety information invalidating the earlier positive benefit-
risk-assessment that could significantly affect the continuation of the trial
3. Violation of GCP, the CTP, or the contract disturbing the appropriate conduct of the trial
The Investigator / the trial site will be reimbursed for reasonable expenses incurred in case of 
trial termination (except in case of the third reason).

4.1.3
Method of assigning patients to treatment groups
All treatments will be double-blind as to be indistinguishable for the patient as well as for the 
investigator. Patients are randomised to treatment groups at Visit 2. Note that the medication 
number is different from the patient number (the latter is assigned directly after informed 
consent was obtained). Site personnel will enter the medication number on the case report 
form/in the CRF.
During visit 2 eligible patients will be randomised to receive a 2:1:1:1:2 ratio according to a 
randomisation plan (see figure 3.1: 1 for details). The assignment will occur in a blinded 
fashion via Interactive Response Technology (IRT).
4.1.4
Drug assignment and administration of doses for each patient
IRT will allocate medication kit numbers at Visit 2, 4, and 6. The amount of trial medication 
dispensed and returned will be recorded on drug accountability forms.
For blinding reasons all treatments will consist of five tablets verum or placebo to be taken 
within 10-15 minutes in the morning depending on the treatment arm. This will not be 
changed during the entire study treatment period (V2-EOT). 
For days without site visits, patients should be instructed to take the tablets orally with water 
in the morning before breakfast at approximately the same time every day without food
(defined as no food intake until 60 mins after dosing). If a dose is missed by more than 8hrs, 
that dose should be skipped and the next dose should be taken as scheduled. No double doses 
should be taken and dose reductions are not permitted. Patients should be instructed to bring 
all unused drug and empty study blister to the study site.
Patients should be instructed NOT to take their study medication on the morning of scheduled 
trial visits. The first dose of study medication will be taken at the visit 2 under supervision of 
the investigator or site staff. At all site visits the morning dose of the investigational drug will 
be taken during the visit under supervision of the investigator or relevant site staff. The actual 
visit date and time of study drug administration at the trial visit will be recorded in the eCRF 
at each visit. Patients should be fasted at the beginning of the study visit. Patients who 
erroneously take the morning dose of study medication before coming to the clinic at a visit 
with scheduled PK samples should have the visit rescheduled as soon as possible, ideally on 
the following day. Patients will record the administration dates and times of all doses with the 
help of a diary as outlined in the Flow Chart and in Section 6.2.2.

4.1.5
Blinding and procedures for unblinding
Blinding
4.1.5.1
Patients, investigators and everyone involved in trial conduct or analysis or with any other 
interest in this double-blinded trial will remain blinded with regard to the randomized 
treatment assignments until after database lock. Please refer to Section 4.1.5.2 for rules of 
breaking the code for patients in emergency situations.
The randomization code will be kept secret by Clinical Trial Support up to database lock. The 
randomization codes will be provided to bioanalytics prior to last patient out to allow for the 
exclusion from the analyses of PK samples taken from placebo patients and to a member of 
the unblinded team in preparation of a possible interim PK/PD analysis. Bioanalytics will not 
disclose the randomization code or the results of their measurements until the trial is 
officially unblinded.
A possible interim PK/PD analysis will be performed by an unblinded team independent from 
the trial and project teams to maintain the blinded conduct of the study. Results of the interim 
analysis will only be presented as aggregated data and not on subject level to maintain 
blinding. The logistical aspects of conducting the interim PK / PD analysis, and the plan to 
access of interim results will be described in the Interim Analysis Logistics Plan and Results 
Access Plan.
Unblinding and breaking the code
4.1.5.2
Emergency unblinding will be available to the Investigator / Pharmacist / investigational drug 
storage manager via IRT. It must only be used in an emergency situation when the identity of 
the trial drug must be known to the Investigator in order to provide appropriate medical 
treatment or otherwise assure safety of trial participants. The reason for unblinding must be 
documented in the source documents and/or appropriate CRF page along with the date and 
the initials of the person who broke the code.
Due to the requirements to report Suspected Unexpected Serious Adverse Reactions 
(SUSARs), it may be necessary for a representative from Boehringer Ingelheim’ s
Pharmacovigilance group to access the randomisation  code for individual patients during 
trial conduct. The access to the code will only be given to authorised Pharmacovigilance 
representatives and not be shared further. 
4.1.6
Packaging, labelling, and re-supply
The investigational products will be provided by BI or a designated CRO. They will be
packaged and labelled in accordance with the principles of Good Manufacturing Practice 
(GMP). Re-supply to the sites will be managed via an IRT system, which will also monitor 
expiry dates of supplies available at the sites.
For details of packaging and the description of the label, refer to the ISF.

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 storage conditions on the medication label. IMP needs to 
be shipped and stored under refrigerated conditions (2-8°C / 36-46°F). A temperature log 
must be maintained for documentation.
If the storage conditions are found to be outside the specified range, the local clinical monitor 
(as provided in the list of contacts) must be contacted immediately.
4.1.8
Drug accountability
The Investigator, Pharmacist or investigational drug storage manager will receive the 
investigational drugs delivered by the sponsor when the following requirements are fulfilled:

Approval of the trial protocol by the IRB / ethics committee 

Availability of a signed and dated clinical trial contract between the sponsor
and the head of the investigational site,

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

Availability of the proof of a medical license for the principal Investigator

Availability of Form 1572
The Investigator, Pharmacist or 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 patient, and 
the return to the sponsor or warehouse / drug distribution centre or alternative disposal of 
unused products. If applicable, the sponsor or warehouse / drug distribution centre will 
maintain records of the disposal. 
These records will include dates, quantities, batch / serial numbers, expiry (‘use- by’) dates, 
and the unique code numbers assigned to the investigational product and trial patients. The 
Investigator / Pharmacist / investigational drug storage manager will maintain records that 
document adequately that the patients were provided the doses specified by the CTP and 
reconcile all investigational products received from the sponsor. At the time of return to the 
sponsor< and/or >appointed CRO, the Investigator / Pharmacist / investigational drug storage 
manager must verify that all unused or partially used drug supplies have been returned by the 
clinical trial patient and that no remaining supplies are in the Investigator’s possession.

TREATMENT COMPLIANCE
4.3
Patients are requested to bring all remaining trial medication including empty package 
material with them when attending visits.
Based on tablet counts, treatment compliance will be calculated as the number of tablets
taken, divided by the number of tablets which should have been taken according to the 
scheduled period, multiplied by 100. Compliance will be verified by the on-site monitor 
authorised by the sponsor.
Treatment compliance (%) =
Number of tablets actually taken 100
Number of tablets which should have been taken
If the number of doses taken is not between 80-120%, site staff will explain the patient the 
importance of treatment compliance.

VARIABLES AND THEIR ASSESSMENT
5.
TRIAL ENDPOINTS
5.1
5.1.1
Primary Endpoint(s)
The primary endpoint is the plasma amine oxidase copper-containing 3 (AOC3) activity 
relative to baseline in %, 24 h post dose, after 12 weeks of treatment. The baseline is defined 
as the last AOC3 activity measurement prior to administration of any randomised study 
medication.

Secondary Endpoint(s)
Safety and tolerability will be assessed based on the number (%) of subjects with adverse 
reactions.
The secondary biomarker endpoints will be assessed based on the
relative ALT change from baseline after 12 weeks of treatment
relative AST change from baseline after 12 weeks of treatment
relative AP change from baseline after 12 weeks of treatment
relative -GT change from baseline after 12 weeks of treatment
relative caspase cleaved cytokeratin 18 (M30) change from baseline after 12 weeks of

ASSESSMENT OF SAFETY
5.3
5.3.1
Physical examination
A full physical examination will be performed at the visits indicated in the Flow Chart. This 
should be performed according to medical standards and usually includes (but is not 
necessarily limited to) a review of the following organ systems: General appearance 
(including Skin), Head-Eyes-Ears-Nose-Throat (HEENT), Chest (including Pulmonary and 
Heart), Abdomen, Extremities, Urogenital  and neurological assessment (basic mental status, 
cranial nerves, motor system, sensation, cerebellum/coordination). Clinically relevant 
abnormal findings noticed after randomisation will be reported as (S)AEs. At all other visits 
according to the Flow Chart a symptom-derived physical examination should be performed.
This includes vital sign assessment as well as an evaluation of the organ systems associated 
with AE(s) symptoms or laboratory abnormalities.
Clinically significant abnormal findings will be reported as baseline conditions or AE’s.
Waist and hip circumference
5.3.1.1
Waist and hip circumference will be measured at screening and EOT/ED visit. 
Waist circumference measurements should be made around a patient’s bare midriff, after the 
patient exhales while standing without shoes and with both feet touching and arms hanging 
freely. The measuring tape should be placed perpendicular to the long axis of the body and 
horizontal to the floor and applied with sufficient tension to conform to the measurement 
surface. Waist circumference should be determined by measuring the midpoint between the 
lowest rib and the iliac crest.
Hip circumference measurement should be taken around the widest portion of the buttocks.
Body weight
5.3.1.2
The scale used to capture body weight for each patient should remain consistent during the 
trial. In order to get comparable body weight values, it should be performed in the following 
way:
- Fasting (except for the screening visit);
- After the urine sampling (body weight after bladder voiding);
- Shoes and coat/jackets should be taken off; and
- Pockets should be emptied of heavy objects (i.e. keys, coins etc.)
5.3.2
Vital Signs
Systolic and diastolic blood pressure (BP), respiratory frequency (RF) and pulse rate (PR) 
will be measured after the patient has rested for at least 5 min in the sitting position.

Measurement of vital signs should precede blood sampling to avoid the impact of blood 
sampling on the vital measurements. The measured vital signs will be documented in the 
source documents and recorded in the eCRF.
5.3.3
Safety laboratory parameters.
Parameters that will be determined during the trial conduct are listed in Table 5.3.3: 1 and 
will be collected by the trial site at the time points indicated in the Flow Chart. All analyses 
will be performed by a central laboratory. Patients have to be fasted (except for the screening 
visit) for at least 8 h before the blood sampling for the safety laboratory. The respective 
reference ranges and details about sample handling shipment and results reporting will be 
provided in the ISF (Lab Manual).
Clinically significant abnormal findings will be reported as baseline conditions or AE’s.

5.3.4
Electrocardiogram
Printed paper traces from 12-lead ECGs in triplicate will be recorded at the visits outlined in 
the flowchart for all patients approximately 90 min after study drug intake. At visits without 
drug administration ECGs should preferentially be performed prior blood sampling. Please 
refer to the Flow Charts 1, 2, 3 and 4 for exact timing. ECGs will be recorded after the 
patients have rested for at least 5 minutes in a supine position. Six limb leads, as specified by 
Einthoven (I, II and III) and Goldberger (aVR, aVL, aVF), and six pre-cordial leads (V1–
V6), according to Wilson, will be used. ECGs may be repeated for quality reasons and the 
repeated recording used for analysis.
In the event of any clinical cardiac symptoms (e.g. suspicion of heart rhythm disorders or 
cardiac ischaemia), an additional ECG will be recorded at the investigator´s discretion.
At screening visit all triplet ECGs will be printed and evaluated (signed, dated and 
commented upon) by the treating physician/ investigator and will be filed in the patient’s
source documents. This will be used as baseline before the first drug administration.
At all other visits, only the first of the three replicate ECGs at a single assessment time will 
be evaluated by the treating physician/ investigator and stored locally. The remaining second 
and third replicate ECGs will be printed and kept together with other medical records of the 
patient for additional analyses if required at a later time point.
All ECGs recorded during trial conduct including the baseline ECG will also be transmitted 
to a vendor for central evaluation and stored at an external central ECG database. Only the 
first of the three replicate ECGs at a single assessment time will be centrally evaluated and 
transferred to the sponsor. The results of the centralized evaluation will be sent from the ECG 
core lab to the sponsor according to a pre-specified data transmission agreement. The 
remaining second and third replicate ECGs will only be stored at the ECG vendor for 
additional analyses if required at a later time point. The central reader’s evaluation of the 
tracing is considered the official reading for the trial.

In case of discrepancies between investigator and central reading, the central evaluation will 
be valid.
Clinically significant abnormal findings will be reported either as baseline condition (if
identified at the screening visit) or otherwise as adverse events and will be followed up
and/or treated locally until normal or stable condition.
Information about the details of ECG collection will be provided in the ISF.
5.3.5
Assessment of adverse events
Definitions of AEs 
5.3.5.1
Adverse event
An adverse event (AE) is defined as any untoward medical occurrence in a patient or clinical 
investigation subject administered a medicinal product and which does not necessarily have 
to have a causal relationship with this treatment.
An AE can therefore be any unfavourable and unintended sign (including an abnormal 
laboratory finding), symptom, or disease temporally associated with the use of a medicinal 
product, whether or not considered related to the medicinal product.
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, or
-
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 classified as a serious 
event regardless of the duration between discontinuation of the drug and must be reported as 
described in 5.3.5.2, subsections “AE Collection” and AE reporting to sponsor and 
timelines”
In accordance with the European Medicines Agency initiative on Important Medical Events, 
Boehringer Ingelheim has set up a list of further AEs, which by their nature, can always be 
considered to be “serious” even though they may not have met the criteria of an SAE as 
defined above.
The latest list of “Always Serious AEs” can be found in the EDC system. 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:
Hepatic injury
A hepatic injury is defined by the following alterations of hepatic laboratory and clinical 
parameters as defined by the removal and stopping criteria in section 3.3.4.1.1 and section
10.3.
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 (e.g. encephalopathy, nausea, vomiting, 
pruritus, severe fatigue, icterus, 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 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].
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:
1. The event is consistent with the known pharmacology of the drug 
2. The event is known to be caused by or attributed to the drug class.
3. A plausible time to onset of the event relative to the time of drug exposure.
4. Evidence that the event is reproducible when the drug is re-introduced
5. No medically sound alternative aetiologies that could explain the event (e.g. pre-existing
or concomitant diseases, or co-medications).
6. The event is typically drug-related and infrequent in the general population not exposed 
to drugs (e.g. Stevens-Johnson syndrome).
7. 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:
1. 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)
2. 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.
3. 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).
4. Disappearance of the event even though the study drug treatment continues or remains 
unchanged.

Adverse event collection and reporting
5.3.5.2
AE Collection
The Investigator shall maintain and keep detailed records of all AEs in their patient files.
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 patient’s end of trial:
o
all AEs (serious and non-serious) and all AESIs.
However, if an individual patient discontinues trial medication prematurely but stays 
in the trial (i.e. if further visits incl. telephone visits, or vital status assessments are 
planned) from then on and until the individual patient’s end of the trial the 
Investigator must report related SAEs and related AESIs.

After the individual patient’s end of trial: 
the Investigator does not need to actively monitor the patient for AEs but should only 
report relevant SAEs and relevant AESIs of which the Investigator may become 
aware of.
As the REP is to be explored in this trial, it is considered as the entire FU period from last 
dose administration of trial medication until individual patient’s end of trial. 
All AEs which occurred through the treatment phase until entire Follow-up period will be 
considered as on treatment, please see section 7.3.4. 
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 
CRF pages and the BI SAE form. 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 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 patient’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.

Biochemical and cellular biomarkers
Concentration and activity of AOC3 in plasma will be measured at the time points indicated 
in the Flow Charts 1, 2, 3, 4 and in Section 10.1. The values determined prior to the first 
dosing of BI 1467335 will be defined as baseline.
AOC3 activity per time point will be presented relative to baseline. AOC3 concentration will 
be presented as absolute values and relative to baseline.
The following parameters will be determined for plasma AOC3 activity relative to baseline, if 
feasible; after multiple dosing the parameters will be denoted with the index ‘N’, where N is 
the number of doses administered.
Emax (maximum plasma AOC3 activity relative to baseline within the dosing interval)
Emin (minimum plasma AOC3 activity relative to baseline within the dosing interval)
tmax (time from dosing to reach Emax)
tmin (time from dosing to reach Emin)
Epre,N (plasma AOC3 activity relative to baseline prior to the Nth dose of BI 1467335)
.
For the secondary endpoints ALT, AST, ALP, -GT, caspase cleaved cytokeratin 18 (M30) 
and total cytokeratin 18 (M65) samples will be collected as described in the Flow Chart 1.
Relative changes from baseline in ALT, AST, AP,-GT and Cytokeratine18 fragments after 
2, 4, 8, 12 weeks of treatment and 4 weeks after last dose will be determined.
 
 
 
 
 
For the endpoints and exploratory biomarkers clear endpoint definitions and further details on 
evaluation will be provided in the TSAP.

5.5.3
Methods of sample collection
For the measurement of the activity and the concentrations of AOC3 4.0 ml of blood will be 
taken from an antecubital or forearm vein into a K2-EDTA anticoagulant blood drawing tube 
at the time points indicated in the Flow Chart. 2 x 4.0 ml will be taken at Visit 2 to have a 
back-up sample for the pre-dose value.  
Blood will be withdrawn by means of either an indwelling venous catheter or by 
venepuncture with a metal needle.
For the secondary endpoints and the exploratory biomarkers evaluation approximately 23 ml 
of blood (10 ml for K2-EDTA blood and 10 ml for serum and 3ml for sodium citrate 
coagulation tube) will be taken at the time points indicated in the Flow Chart 1. Blood will be 
withdrawn by means of either an indwelling venous catheter or by venepuncture with a metal 
needle.
Further details on collection, handling, storage and processing of the blood sample will be
provided in a separate laboratory instruction manual.
All left over samples will be stored and used for not yet specified explorative investigations. 
These samples will be stored for up to three years after the end of the clinical trial and may be 
used for not yet specified biomarker analyses to enable further characterization of metabolic 
diseases and their progress, as well as method development and evaluation. Results of these 
assessments will not be part of the Clinical Trial Report.

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 5.4 are generally used assessments of drug exposure.

INVESTIGATIONAL PLAN
6.
VISIT SCHEDULE
6.1
All patient visits should be scheduled according to the Flow Chart. Each visit date
(with its window) is to be counted from Day 1. If any visit has to be rescheduled, subsequent 
visits should follow the original visit schedule. The trial medication packs contain sufficient 
medication to allow for these time windows.
All trial visits should be initiated preferentially in the morning starting before 9:00 AM. 
Patients should be instructed to avoid intake of the morning dose of the study medication at 
home at scheduled visit days as they will be dosed whilst at the study site.
Study measurements and assessments according to the Flow Chart scheduled to occur before 
study drug administration on Day 1, 15, 29, 43, 57 and 85 are to be performed and completed 
within a 2 h-period prior to the study drug administration.
Unscheduled visits will be possible at the discretion of the investigator at any time in order to 
check the safety of the patient.
If the reason for removal of a patient from the treatment is an adverse event or an abnormal 
laboratory test result, the patient must be followed until complete resolution or stabilization 
of the event or until follow-up is agreed adequate by the Investigator and BI Clinical Monitor.
DETAILS OF TRIAL PROCEDURES AT SELECTED VISITS
6.2
6.2.1
Screening 
Screening Period
All patients must sign an Informed Consent consistent with ICH-GCP guidelines and the 
local legislation prior to any study specific procedures. Once they have consented, the patient 
is considered to be enrolled in the trial and have started screening. The patient should be 
recorded on the enrolment log and be registered in IRT as a screened patient. Patients will be 
assigned a patient number and enrolment must be recorded in eCRF pages. The Screening 
period is defined as the period from the Screening visit to Randomisation (first study drug 
administration). The screening period should be no longer than 28 days and no less than 7 
days and will be used to assess eligibility of the patients. Thus patients will not be 
randomized until all screening procedures are completed and results are reviewed to verify 
study eligibility. Please refer to Section 8.1. 
For the comprehensive list of the trial procedures required at the Screening Visit (Visit 1) 
please refer to the Flow Chart.
Patients are allowed to repeat lab testing once during the screening period.
For those patients with historic ALT > 1.25 ULN value more than 3 months prior to 
screening, the ALT > 1.5x ULN  must be confirmed via two measurements at least 1 week 
apart within the screening period.

Patients without required clinical imaging results suggestive of NASH (no more than 3 years 
prior to screening, according to inclusion criterion #1), clinical imaging can be performed as 
optional procedure during the screening period. The imaging procedures will be performed 
according to local standards. Please refer to Flow Chart 1.
No imaging is required if histological evidence of NASH (no more than 3 years prior to 
screening) is available. Please refer to section 3.3.2
Demographics
Information on race will be collected because this is required for the calculation of eGFR 
(CKD-EPI formula).
Re-screening
Patients who screen-fail the study after Visit 1 should be registered in the IRT as a screen 
failure within the protocol defined screening period.
Re-screening of not yet randomised patients can be allowed in exceptional cases but should 
be discussed on a case-by-case basis between the study site, Monitor staff and with the TCM.
IRT
All patients that are screened must be registered with IRT. If the patient results in a screen 
failure, IRT should be notified as soon as possible and within the 28- day screening period.
Details of IRT procedures can be found in the IRT manual located in the ISF
6.2.2
Treatment period
Visits 2, 3, 4, 5, 6 and EOT
The treatment period consists of a maximum of 6 visits (visits 2 - EOT). Visit 2 is the 
randomisation visit and visit EOT is the end of treatment visit, where the last dose of 
medication will be administered. Procedures are to be performed according to the flowcharts 
1, 2, 3, 4, section 10.1 and the respective protocol sections.
Safety laboratory testing
Patients should be fasted (no food and only water) for at least 8 hours prior to the start of 
procedures until 60 mins after drug intake. If a patient comes in non-fasted where a fasting 
condition is required, the visit should be performed, the non-fasted condition documented on 
the laboratory requisition, and the patient reminded about the expected condition. 
Pregnancy testing
Urine pregnancy testing for all women of childbearing potential will be conducted on-site 
prior to every dosing and must be negative to further treat the patient. A positive urine test 
must be confirmed with a serum pregnancy test.
Randomisation (Visit 2)
Randomisation via IRT and administration of the first dose of study medication will occur at 
Visit 2.

Study drug diary 
The study patients will be instructed to complete a study drug diary during the treatment 
phase to document drug intake (date and time) and number of the tablet row indicating the 
day of intake between the on-site visits.
The diary will be dispensed to the patients at Visit 2 and the patient´s entries will be checked 
by site-staff during the consecutive treatment visits. Selected entries (drug administration date 
and time 3 days prior to each visit) will be entered by site-staff into the CRF.
Pharmacokinetic and biomarker blood sampling
The blood sampling times given in Section 10.1 are the recommended sampling times relative 
to the drug administration and should be adhered to as closely as possible. The actual times of 
drug administration and blood samplings will be recorded in the CRF.
Please refer to the Flow Charts 1, 2, 3 and 4 for exact timing.
 
 
 
 
Telephone contacts
Day 27/ Phone Call 3A: 
The site staff should call the patients on day 27 to remind them of the urine collection starting
directly after the drug administration at day 28 (24h prior to planned visit 4/ day 29 drug 
administration) and study drug intake.
Day 83/ Phone Call 6A: 
The site staff should call the patients on day 83 to remind them of study drug intake on day 
84. Please refer to section PK urine collection above and Flow Charts 1, 4 and section 10.1.
End of Treatment (EOT) Visit/ Early Discontinuation (ED):
If the regular end of the treatment period at week 12 is reached, the EOT Visit will be 
completed. The time interval for the regularly scheduled EOT Visit is 4 days, i.e. Day 85+3. 
The overall duration of the treatment period (randomisation to EOT) should not be less than 
85 days.
If the patient refuses to continue the treatment in the trial or must stop treatment the early 
discontinuation (ED) Visit will be completed instead of the planned treatment period visit. 
This early discontinuation visit will include the same procedures as the normal EOT visit 
except drug administration, PK, PG and PD sampling. Visit FU should be performed no later 
than four weeks after the last study drug intake.

It is important to distinguish between premature study drug discontinuation and complete 
withdrawal of consent to participate in further study procedures. Patients not willing to 
continue study drug intake should be asked to further attend scheduled trial visits, follow-up 
visits and assessments until the end of the trial unless they withdraw consent to participate in 
the study. For patients who discontinue IMP but are willing to attend scheduled trial visits,
the early discontinuation (ED) Visit will be completed according to FlowChart instead of the 
next planned treatment period visit. All following visits should be performed according to the 
initial study schedule (without study drug administration). In addition to the safety sampling,
only one PK sample and one PD blood sample for measurement of AOC3 activity should be 
taken at each visit on which PK and/or PD sampling was originally planned and the actual 
time of the blood draw recorded. One of these remaining visits should be performed no later 
than four weeks after the last study drug intake.
Should it not be possible to attend all visits, at least phone contacts should occur at the 
scheduled visits time points. It is vital to explain to these patients the importance to continue 
trial participation.
All unused study medication will be collected and the study drug diary will be checked by the 
site. Procedures are to be performed according to the Flow Chart.
6.2.3
Follow Up Period and Trial Completion
Follow-up (FU):
This visit will be performed 28±3 days after EOT (see Flow Chart 1 and Section 10.1 for 
procedures to be performed).
In case of early discontinuation this visit will include the same procedures as the normal FU
visit except PG and PD sampling.
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.
Trial completion:
Trial completion is defined as patients completing the FU visit within the specified window 
per the flow chart and who have not discontinued drug prematurely.

STATISTICAL METHODS AND DETERMINATION OF
7.
SAMPLE SIZE
STATISTICAL DESIGN - MODEL
7.1
See Section 3.1 for details on the design of the study.
See Section 2.2 for details on the objective of the study.
Primary endpoint is the plasma AOC3 activity relative to baseline in %, 24 hours post dose,
after 12 weeks of treatment. Baseline is defined as the last measured plasma AOC3 activity 
prior to administration of any randomised study medication.
The dose-response relationship of the primary endpoint will be analysed using a nonlinear 
regression model applied to the AOC3 activity at week 12. The fitted regression model will 
be used to derive the smallest dose where the mean plasma AOC3 activity curve drops below 
10% (D10). This corresponds to:
D10 = min { ∈[0,10]| ()
 ≤10%}
where d is the dose and ()
 is the fitted dose-response curve described in Section 7.3.1.
The analyses of the secondary biomarker endpoints ALT AST, AP, -GT and CK18 
fragments will follow the MCPmod approach allowing for the simultaneous evaluation of 
different potential dose response patterns, whilst protecting the overall probability of type I 
error (one-sided alpha of 0.05).
NULL AND ALTERNATIVE HYPOTHESES
7.2
In this trial it is not planned to test any statistical hypotheses in a confirmatory sense. Where 
statistical testing is used it will have to be interpreted in the perspective of the exploratory 
character of the study.
No hypothesis testing will be used for the primary analysis of the primary endpoint.
The analyses of the secondary biomarker endpoints ALT, AST, AP, -GT and CK18 
fragments contain hypotheses testing. The null hypothesis is that there is a flat dose response 
pattern across placebo and any dose of BI 1467335 within the tested dose range (0-10mg).
The alternative hypothesis is that there is a non-flat dose response pattern indicating a benefit 
of BI 1467335 compared to placebo.

PLANNED ANALYSES
7.3
The following patient analysis sets are defined for this trial:

Treated Set (TS): includes all patients who signed informed consent and were treated 
with at least one dose of the trial medication. Patients in TS are analyzed under the 
actual trial medication received at randomisation. The TS is used for safety analyses
as well as demographics and baseline characteristics.

Full Analysis Set (FAS): includes all patients in treated set who had non-missing 
baseline and at least one non-missing post-baseline and on-treatment measurement on 
any biomarker endpoint. Patients in FAS are analyzed according to the intent-to-treat 
principle, i.e., patients in FAS are analyzed under the randomized trial medication. 

Per protocol set (PPS): includes all patients from the FAS without important protocol 
violations (IPV) leading to exclusion. This includes:
Compliance to randomised treatment within 80% -120% (inclusive)
At least 80% treatment compliance within 4 weeks before last visit
 
Data from subjects who are screened but not randomised will be listed but not included in any 
summary statistics or inferential statistics. Specifications of important protocol violations 
leading to exclusion will be provided in the TSAP.
Further Analysis sets will be defined in the TSAP.

Primary endpoint analyses
The primary analysis of the primary endpoint will be based on the PPS. 
The subject specific plasma AOC3 activity at time t relative to baseline in % is calculated via
%3 ∶=  !3 − 3,#$%&' !3#$() −3#$(),#$%&'
*

Where 3 is the AOC3 activity measured at time t, 3,#$%& is the background 
noise at time t, 3#$() is the AOC3 activity measured at baseline and 3#$(),#$%& is 
the background noise at baseline.
As the primary endpoint should show a reduction in AOC3 activity with higher doses, a 
decreasing 3-Parameter regression curve will be used of the form

Note that the dose-response relationship is assumed to asymptotically approach 0% at high 
doses. 
As it is expected to see a higher variability in AOC3 activity measurements in placebo treated 
patients then in patients treated with BI 1467335 the model fit will use power of mean 
variance estimates (POM) to account for heterogeneity.
In case of the 24h value after drug administration at week 12 is missed, the -0:30 values at 
week 12 can be used instead. In case of other missing AOC3 activity values, except of 
missing baseline where no imputation is done, multiple imputation will be used. After 
exploring the missing data mechanism and observed measurements on the blinded data the 
variable AOC3 activity relative to baseline in % will be included in the imputation model.
If the data is monotone missing, a regression model will be used for imputation including
baseline AOC3 activity, and AOC3 activity relative to baseline measurements predose (-
0:30h relative to drug administration) at Visit 4 and 6 and 24h relative to drug administration 
at visit 3,5 and EOT by treatment.
In the case of non-monotone missing, a Markov chain Monte Carlo (MCMC) step will be 
used to create monotone missing data in multiple datasets. The regression method will then 
be used to complete the imputation in each dataset. For each imputed complete dataset, the 
decreasing 3-parameter curve model will be used for the analysis. The results will be pooled 
following the standard multiple imputation procedure.
The dose where the model fit drops below 10% and the 95% confidence interval will be 
determined (D10). The fitted curve will be graphically displayed.

7.3.2
Secondary endpoint analyses
The number (%) subjects with adverse reactions will be evaluated descriptively on the TS. 
For more details see Section 7.3.4.
The primary analysis of the secondary biomarker endpoints will be first analysed using a 
repeated measurement analysis (MMRM) on the PPS. The relative ALT (AST, AP, -GT and 
CK18 fragments respectively) changes from baseline at visit 3,4,5,6 and EOT will be 
evaluated on log scale using an MMRM accounting for the following sources of variation: 
‘baseline’, ‘visit’, ‘treatment’, ‘visit*treatment’ and ‘visit*baseline’ interaction as fixed effect 
as well as the random ‘subject’ effect. The unstructured covariance structure will be used to 
model the within patient measurements. To estimate denominator degrees of freedom the 
Kenward-Roger approximation will be used.
The dose-response relationship of the week 12 estimates from MMRM will then be analysed 
using MCPMod. A set of plausible dose response patterns is considered with pre-specified 
parameters define:
The following model assumptions have been selected to cover a plausible and diverse range 
of dose response patterns when having matching Placebo and active BI 1467335 doses of 1 
mg, 3 mg, 6 mg and 10 mg:

Linear: no assumptions needed

Linear logistic no assumptions needed

Quadratic: 90 % of the maximum effect is achieved at 7 mg

Exponential: 90 % of the maximum effect is achieved at 7 mg

Emax: 90 % of the maximum effect is achieved at 7 mg

Sigmoidal Emax: 30 % of the maximum effect is achieved at 3 mg and 90 % of 
the maximum effect is achieved at 7 mg

Logistic: 30 % of the maximum effect is achieved at 3 mg and 90 % of the 
maximum effect is achieved at 7 mg

Betamod: 90 % of the maximum effect is achieved at 5 mg, maximum effect is 
achieved at 4 mg and maximal dose is 10 mg

Figure 7.3.2: 1 Defined MCPMod shapes to be used.
If there is a at least one significant model, the null hypothesis of a flat dose-response 
relationship for the secondary endpoint ALT ( for AST, AP, -GT and CK18 fragments 
respectively) jointly for each of the candidate dose-response models with a contrast test 
controlled for the family-wise error rate (α = 0.05 1-sided) will be rejected.
When the null hypothesis is rechecked, the best-fitting model from the above set of eight
models can be refitted to the data without any parameter assumptions to generate new 
estimates of the model parameters from the data. The target dose will be obtained via model 
averaging across the significant models based on Akaike Information Criterion (AIC) (the 
smaller the AIC value the better the model fit). The target dose(s) can then be determined 
from that model by incorporating information on the minimum clinically relevant effect as 
well as safety information. 
Further details on the primary analysis, 
 will be 
provided in the TSAP.

7.3.4
Safety analyses
Adverse events will be coded using the Medical Dictionary for Regulatory Activities 
(MedDRA) coding dictionary. Standard BI summary tables and listings will be produced. All 
adverse events with an onset between start of treatment and individual patient’s end of trial
will be assigned to the treatment period for evaluation.
The analysis will be done by ‘treatment at onset’.
All treated patients will be included in the safety analysis (analysis on TS). In general, safety 
analyses will be descriptive in nature and will be based on BI standards. No hypothesis 
testing is planned.
Statistical analysis and reporting of adverse events will concentrate on treatment-emergent 
adverse events. To this end, all adverse events occurring between start of treatment and 
individual patient’s end of trial will be considered ‘treatment-emergent’. Adverse events that 
start before first drug intake and deteriorate under treatment will also be considered as 
‘treatment-emergent’.
Frequency, severity, and causal relationship of adverse events will be tabulated by system 
organ class and preferred term after coding according to the current version of the Medical 
Dictionary for Drug Regulatory Activities (MedDRA). Frequency tables for all adverse 
events, protocol-specified AESI, serious adverse event (SAE), adverse event leading to death, 
adverse event leading to discontinuation, investigator assessed drug-related adverse event and 
serious adverse event will be generated for treatment-emergent adverse events.
Laboratory data will be analysed both quantitatively as well as qualitatively. The latter will 
be done via comparison of laboratory data to their reference ranges. Values outside the 
reference range as well as values defined as clinically relevant will be highlighted in the 
listings. Treatment groups will be compared descriptively with regard to distribution 
parameters as well as with regard to frequency and percentage of patients with abnormal 
values or clinically relevant abnormal values.
Vital signs, physical examinations, or other safety-relevant data observed at screening, 
baseline, during the course of the trial and at the end-of-trial evaluation will be assessed with 
regard to possible changes compared to findings before start of treatment.

INTERIM ANALYSES
7.4
An interim PK/PD analysis may be performed for model development purposes of the 
population PK and PK/PD analysis and to support dose decision for future trials. The interim 
analysis will focus on PK and AOC3 inhibition; other secondary biomarker endpoints may be 
evaluated in addition. The exact time point for data cut-off will be aligned with other studies 
investigating BI 1467335 and general project planning. Details of this analysis will be 
defined in the interim PK/PD analysis plan.
The result of the interim analysis will not be used to make any adaptions of the trial like 
sample size adjustments.
For steps to maintain blinding during the interim analysis see Section 4.1.5.1.  
HANDLING OF MISSING DATA
7.5
Primary and secondary biomarker endpoints
Every effort will be made to collect complete data at the specified time points.
If missing values still occur they will be handled as described in the corresponding section.
Safety
With respect to safety evaluations, it is not planned to impute missing values.
 
RANDOMISATION
7.6
Patients will be randomised in blocks to double-blind treatment in a 2:1:1:1:2 ratio (Placebo, 
1 mg, 3 mg, 6mg and 10 mg respectively). The randomisation of patients to the treatment 
groups will be performed via an interactive response technology (IRT). 
BI will arrange for the randomisation and the packaging and labelling of trial medication. The 
randomisation list will be generated using a validated system, which involves a pseudo-
random number generator so that the resulting treatment will be both reproducible and non-
predictable. The block size will be documented in the CTR. Access to the codes will be 
controlled and documented.

DETERMINATION OF SAMPLE SIZE
7.7
The sample size calculation is based on both, plasma AOC3 activity relative to baseline and 
ALT change from baseline, the latter being the biomarker with the least favorable ratio of 
anticipated effect size to variance.
Under the assumptions given in detail below, a sample size of 98 with an allocation ratio of 
2:1:1:1:2 for Placebo, 1 mg, 3 mg, 6mg and 10 mg respectively is appropriate for both the 
estimation of D10 of plasma AOC3 activity relative to baseline and the MCPMod analysis of 
biomarkers. This assumes 98 evaluable patients for the primary and secondary endpoints and 
thus around 108 will need to be randomized. For the dose assessment the lowest (Placebo) 
and highest (10 mg BI 1467335) dose groups will have the highest impact on the analysis. 
Due to the nature of the dose- response-relationship, the biggest difference is anticipated 
between Placebo and the 10 mg group. The power analysis and simulation via MCPMod 
supported the 2:1:1:1:2 allocation ratio instead of equal allocations (see also Table 7.7:1).
ALT
Sample size is based on four assumptions:

an assumed maximum effect size of BI 1467335 vs. placebo of 30% for relative 
change from baseline in ALT after 12 weeks of treatment

a target dose of 20% difference to placebo can be estimated

the target dose lies within the tested dose range

MCPMod shapes and guesstimates as described below
The defined response patterns and model assumptions from section 7.3.2 are used.
Further assumptions are a mean baseline ALT of 80 U/L, a placebo effect at week 12 of -10 
U/L and an effect of active treatment at week 12 of -34 U/L, i.e. the true difference between 
the relative change from baseline between placebo and active treatment at week 12 is 
assumed to be 30%. Further on, it is assumed to have a constant coefficient of variation over 
the whole ALT range of 40/80 = 0.5. This assumption is based on external data from 
CENTAUER, GOLDEN and ARAMCHOL (R16-5489; R18-2779; R18-2781; mean baseline 
ALT of 63-78 and respective SD of 31-44) and on blinded estimated SD for baseline ALT 
from 61 patients from this study.
On log scale this corresponds to a change from baseline in the placebo group of -0.14 and in 
the active treatment group of -0.56, i.e. a difference of 0.42. 
An autoregressive correlation structure is assumed with constant variability of ALT on log 
scale regardless of visit and exponentially declining correlation with distance. The correlation 
between measurements at visits four weeks apart are assumed to be 0.7. Consequently, 
correlation between baseline and week 12 is 0.34

MCMod will be applied to change from baseline of ALT at week 12 on log scale. It is 
investigated if (i) the MCPMod testing step rejects the null hypothesis of no dose-response 
relationship at one-sided alpha = 0.05, and (ii) a target dose of 20% difference to placebo, 
corresponding to a Delta on log-scale of 0.26, can be estimated and lies within the tested dose 
range.
Simulations show that under the assumptions given above and assuming a true effect of 30% 
(Situation 3), the probability to fulfil the two conditions is approx. 84% with a sample size 
of 98 using an allocation ratio of 2:1:1:1:2 for doses Placebo, 1 mg, 3 mg, 6mg and 10 mg 
respectively..

Using these parameter estimates, datasets with 98
patients in a 2:1:1:1:2 ratio were simulated (1000 repeats). The D10 of the fitted nonlinear 
curves using simulated data was between 3.95 mg and 5.1 mg, the 5% and 95% quantiles of 
the distribution being 4.2 mg and 4.8 mg, respectively. This precision is considered to be 
sufficient for the purpose of the trial.

The consent and re-consenting process should be properly documented in the source 
documentation.
DATA QUALITY ASSURANCE
8.2
A quality assurance audit/inspection of this trial may be conducted by the sponsor, sponsor’s 
designees, or by IRB / IEC or by regulatory authorities. The quality assurance auditor will 
have access to all medical records, the Investigator’s trial-related files and correspondence, 
and the informed consent documentation of this clinical trial.
RECORDS
8.3
Case Report Forms (CRF) for individual patients will be provided by the sponsor. See 
Section 4.1.5.2 for rules about emergency code breaks. For drug accountability, refer to 
Section 4.1.8.
8.3.1
Source documents
In accordance with regulatory requirements the Investigator should prepare and maintain 
adequate and accurate source documents and trial records that include all observations and 
other data pertinent to the investigation on each trial subject. Source data as well as reported 
data should follow good documentation practices and be attributable, legible, 
contemporaneous, original and accurate. Changes to the data should be traceable (audit trail).
Data reported on the CRF must be consistent with the source data or the discrepancies must 
be explained.
The current medical history of the subject may not be sufficient to confirm eligibility for the 
trial and the Investigator may need to request previous medical histories and evidence of any 
diagnostic tests. In this case the Investigator must make three documented attempts to retrieve 
previous medical records. If this fails a verbal history from the patient, documented in their 
medical records, would be acceptable.
Before providing any copy of patients’ source documents to the sponsor the investigator must 
ensure that all patient identifiers (e.g. patient’s name, initials, address, phone number, social 
security number) have properly been removed or redacted to ensure patient confidentiality.
If the patient is not compliant with the protocol, any corrective action e.g. re-training must be 
documented in the patient file.
For the CRF, data must be derived from source documents, for example:

Patient identification: gender, year of birth (in accordance with local laws and 
regulations)

Patient participation in the trial (substance, trial number, patient number, date 
patient was informed)

Dates of Patient’s visits, including dispensing of trial medication

Medical history (including trial indication and concomitant diseases, if 
applicable)

Medication history

participant meets all inclusion criteria and does not meet any exclusion criteria.
The absence of records (either medical records, verbal documented feedback of 
the patient or testing conducted specific for a protocol) to support 
inclusion/exclusion criteria does not make the patient eligible for the clinical 
trial.
8.3.2
Direct access to source data and documents
The sponsor will monitor the conduct of the trial by regular on-site monitoring visits and in-
house data quality review. The frequency of on-site monitoring will be determined by 
assessing all characteristics of the trial, including its nature, objective, methodology and the 
degree of any deviations of the intervention from normal clinical practice.
The Investigator /institution will allow on-site trial-related monitoring, audits, IRB / IEC 
review and regulatory inspections. Direct access must be provided to the CRF and all source 
documents/data, including progress notes, copies of laboratory and medical test results, which 
must be available at all times for review by the CRA, auditor and regulatory inspector 
(e.g. FDA). The CRA and auditor may review all CRFs and informed consents. The accuracy 
of the data will be verified by direct comparison with the source documents described in 
section 8.3.1. The sponsor will also monitor compliance with the protocol and ICH GCP.
An adaptive approach to clinical trial monitoring will be utilised. The sponsor will perform a 
risk assessment of the trial to determine the extent and nature of monitoring required in order 
to ensure the reliability and robustness of the results. Regular review of risk reports will 
provide sponsor oversight during trial conduct and direct monitoring activities to the areas of 
greatest risk which have the most potential impact to subject safety and data quality.
The Investigator /institution will allow on-site trial-related monitoring, audits, IRB / IEC 
review and regulatory inspections. Direct access should be granted to all source documents 
(paper and e-records) including progress notes, copies of laboratory and medical test results. 
The CRA and auditor may review all CRFs and informed consents. The accuracy of the data 
will be verified by direct comparison with the source documents described in section 8.3.1. 
The sponsor will also monitor compliance with the protocol and ICH GCP.
