BI trial number
1402-0005
Title of trial
A double-blind, randomised, two-way cross-over, single-dose, placebo-controlled
trial to investigate the effects of BI 1358894 on cholecystokinin tetrapeptide (CCK-
4) induced panic symptoms in healthy male subjects 
Principal Investigator
Trial site
Clinical phase
I
Trial rationale
Inhibition of 
 ion channels by BI 1358894 may potentially improve 
affective symptoms and emotion control in patients with affective disorders. The 
pharmacodynamic data obtained in this study will help to detect the 
pharmacological principle of the BI 1358894 compound by demonstrating indirect 
target engagement via downstream pharmacodynamic measures.
Trial objective
To investigate the pharmacodynamic effects of a single dose of BI 1358894 on 
CCK-4 induced anxiogenic/panic-like symptoms using the Panic Symptom Scale 
(PSS) in preselected CCK-4 sensitive healthy volunteers. 
Trial design
Single dose, placebo-controlled, double-blind, randomised, two-way cross-over
Trial endpoint
Primary endpoint: maximum change from baseline of PSS sum intensity score after 
CCK-4 injection
Number of subjects 
total entered
20*
*Screening may include more than 60 healthy subjects who will be exposed to 
CCK-4 to identify subjects with an anxiogenic and panic induced effect in response 
to CCK-4 as until 20 eligible subjects have been identified
each treatment
20 (all to receive both active treatment and placebo)
Diagnosis
Not applicable
Main criteria
for inclusion
Healthy male CCK-4 sensitive subjects, age of 18 to 55 years (inclusive), body 
mass index (BMI) of 18.5 to 29.9 kg/m2 (inclusive)

Duration of treatment
2 single doses of CCK-4 and BI 1358894 or placebo (separated by a washout period 
of at least 17 days between drug administrations), 1 single dose of the provoking 
agent for the preselection of CCK-4 sensitive healthy subjects
Statistical methods
Descriptive statistics will be calculated for all endpoints. The statistical model to 
assess the primary pharmacodynamic endpoint PSS sum intensity score will be a 
mixed effects model including effects for ‘treatment’, ‘period’ and ‘subject’, as well 
as covariates ‘period baseline’ and ‘subject baseline’. Two sided 90% confidence 
intervals (CIs) will be calculated based on the residual error from the mixed model.

1.
Subject must be informed and written informed consent obtained prior to starting any screening procedures. Screening 
procedures include physical examination, check of vital signs, ECG (including rhythm strip of at least 10 sec), safety 
laboratory (including drug screening and alcohol urine test), demographics (including determination of body height and 
weight, smoking status and alcohol history), neurological examination, relevant medical history, concomitant therapy, 
review of inclusion/exclusion criteria and suicidality assessment (C-SSRS). 
2.
The time is approximate; the respective procedure is to be performed and completed within 3 h prior to drug 
administration. Allocation to treatment may be performed at any time following enrolment but must be completed prior 
to (first) drug administration.
3.
If several actions are indicated at the same time point, the intake of meals will be the last action.
4.
End of trial examination includes physical examination, body weight, vital signs, ECG, safety laboratory, recording of 
AEs, concomitant therapies, suicidality assessment (C-SSRS), neurological examination, and PSS
5.
AEs and concomitant therapies will be recorded throughout the trial, but will be specifically asked for at the time points 
indicated in the Flow Chart above.
6.
Sampling times and periods may be adapted based on information obtained during the trial 
 
including addition of samples and visits as long as the total blood volume taken does not exceed 500 mL per subject
7.
Suicidality assessment only at screening, admission to trial site, discharge from trial site and end of trial.
8.
CCK-4 challenge test (CCK-4 injection (50 µg)) is to be performed after subjects have had a standard high-fat meal
except Visit 2, no breakfast is needed at Visit 2. Injection time must be recorded. PSS 
 assessments will be 
determined 5 ± 1, 10±1, 20±1 and 30 ±1 minutes after the injection. The CCK-4 will be administered to the subjects as a 
bolus injection over 5 seconds (maximum of 8 seconds) via a venous cannula.
9.
One additional blood sample for pharmacogenomics analyses will be taken either at Visit 3 or at Visit 4.
10. Standardized assessment of local tolerability using the criteria swelling, induration, heat, redness, pain or other findings.
11. Discharge on Day 9 includes physical examination, vital signs, ECG, safety laboratory, recording of AEs, concomitant 
therapies, suicidality assessment (C-SSRS), PSS
 and a neurological examination.
12. For ambulatory visit examinations, a time window of 3 hours is acceptable. 
13. The time is approximate and could start between 8:00 to 12:00
14. Discharge after screening CCK-4 challenge after confirmation of fitness by PI or designee

Investigator’s Brochure (IB) [c10354149].
1.2.2
Cholecystokinin-tetrapeptide (CCK-4)
Administration of the neuropeptide cholecystokinin-tetrapeptide (CCK-4) induces panic 
attacks both in patients with panic disorder and healthy volunteers in a dose-dependent 
fashion [R19-0565]. No habituation was observed after repeated administration of CCK-4 as 
a provoking agent. It has been shown that panic disorder patients are much more sensitive to 
CCK-4 administration than healthy controls [R19-0564]. Therefore, it has been suggested 
that CCK-4 might be involved in the pathophysiology of panic disorder. 
When rechallenged without any treatment, panic disorder patients did not show any change in 
the behavioral effects of CCK-4 [R19-0625]. In contrast, it has been demonstrated that
administration of agents that are effective in the treatment of panic disorder reduce CCK-4-
induced panic. [R19-0626] investigated the effect of treatment with imipramine on CCK-4-
induced panic in panic disorder patients in an open-label design. They found a marked 
reduction in the number and intensity of panic symptoms when patients were rechallenged 
after the treatment period [R19-0626]. Similarly, Shlik [R19-0560] showed a marked
reduction of intensity and number of panic symptoms after citalopram treatment [R19-0560].

In a placebo-controlled study with fluvoxamine, significant treatment effects on CCK-4-
induced panic attacks were found in panic disorder patients compared to placebo [R19-0628].
An interaction of CCK-4 with several other neurotransmitter systems has been discussed. 
Apart from the serotonergic and noradrenergic system, the gamma-amino-butyric-acid 
(GABA) system also seems to be involved in the pathophysiology of CCK-4-induced panic 
[R19-0627]; [R19-0626].
Administration of 50 μg CCK-4 was well-tolerated in numerous clinical research trials (see 
Section 4.1.2). The CCK-4 related anxiety symptoms show a rapid increase followed by a 
fast decline within a period of 5 minutes. There may be some residual anxiety symptoms after 
10 minutes, but these are usually mild and disappear without any residual symptoms within 
30 minutes. Changes in vital signs (blood pressure, pulse rate, respiratory rate) occur during 
the CCK-4 challenge test. Short lasting changes in pulse rate and blood pressure have been 
observed together with changes in anxiety-status [R18-2695].
The panic symptoms induced by CCK-4 may be expressed by the following potential 
symptoms (all symptoms are covered by the assessment of the Panic Symptom Scale (PSS), 
vital signs and will be thoroughly monitored):

Dyspnea

Dizziness

Faintness

Trembling

Sweating

Nausea

Abdominal stress

Tachycardia

Chest pain or discomfort

Subjects are exposed to risks of study procedures and risks related to the exposure to the trial 
medication.
1.4.1
Procedure-related risks
The use of an indwelling venous catheter or venepuncture for e.g. blood sampling may result 
in mild bruising, and in rare cases, in transient inflammation of the wall of the vein, or nerve 
injury, potentially resulting in paraesthesia, reduced sensibility, and/or pain for an indefinite 
period.
The total volume of blood withdrawn per subject during the entire study will not exceed the 
volume of a normal blood donation (500 mL). No health-related risk to healthy subjects is 
expected from withdrawal of this volume of blood.

Risk minimization (safety precautions and stopping rules)
1.4.2.1.4
The following safety measures will be applied in this study in order to minimize the risk for 
healthy volunteers: 
•
For safety reasons, each treatment period will be divided into 4 cohorts of 5 subjects. 
Each drug administration will be separated by at least 10 minutes and the dosing of 
the cohorts will be separated by at least 2 days. Adequate continuous safety 
monitoring (see below) will be performed before the subsequent cohort is dosed.
•
An extensive safety laboratory will be performed with special focus on full blood 
exam, including CRP and ESR to monitor for potential perivascular/mesenteric 
inflammation (see Flow Chart)
•
Adequate safety monitoring will be performed (e.g. vital signs (including blood 
pressure, pulse rate, respiratory rate), ECGs, safety laboratory tests including hormone 
parameters, visual analogue scales, suicidality, and assessment of adverse events) 
•
Subjects will be hospitalised throughout the study from Day -1 to Day 9 of each 
period and will be discharged only after a formal assessment and confirmation of 
fitness by an investigator or qualified designee. During the in-house stay, the subjects 
will be under medical observation and thoroughly monitored for adverse events, 
which may be reported in an expedited manner if they match the criteria for expedited 
reporting
•
As reproductive toxicity studies have not yet been conducted, only male subjects will 
be enrolled in this study

Drug induced liver injury
1.4.2.1.5
Although rare, a potential for drug-induced liver injury (DILI) is under constant surveillance 
by sponsors and regulators. Therefore, this trial requires timely detection, evaluation, and 
follow-up of laboratory alterations in selected liver laboratory parameters to ensure subjects´ 
safety; see also Section 5.2.6.1.6, adverse events of special interest.
1.4.2.2
CCK-4
The CCK-4 challenge test is well-tolerated, based on numerous clinical studies (see 
Section 1.2.2). CCK-4 induced effects are transient (5 minutes) and include changes in vital 
signs (blood pressure, pulse rate, respiratory rate) and panic symptoms (increased anxiety, 
tremors, sweating, dry mouth, derealization, mild nausea, and a strange feeling in stomach). 
Safety precautions will include thorough monitoring of panic symptoms (via the PSS), vital 
signs, and continuous ECG. Subjects will be hospitalised and kept under close medical 
surveillance for at least 4 hours following CCK-4 administration.
1.4.2.3
Overall assessment
 
 Based upon 
preclinical data for BI 1358894, the preliminary clinical data from the on-going FIH study, 
the well-known safety profile of CCK-4, as well as the implemented safety measures 
described above, healthy subjects will not be exposed to undue risks from BI 1358894 or 
CCK-4 in relation to the important information expected from this trial as a basis for further 
clinical development of this compound. Healthy volunteers are not expected to have any 
direct benefit from participation in the clinical trial with BI 1358894, as is the usual case in 
such Phase I trials. Considering the medical need for the development of a safer and more 
effective treatment for patients 
 the Sponsor 
considers that the benefit outweighs the potential risks and justifies exposure of healthy 
human volunteers.

DESCRIPTION OF DESIGN AND TRIAL POPULATION
3.1
OVERALL TRIAL DESIGN AND PLAN
The study will be performed as a randomised, double-blind, placebo-controlled, two-way 
crossover trial in healthy male subjects in order to compare the test treatment (T) to the 
reference treatment (R). The subjects will be randomly allocated to the two treatment 
sequences (T-R or R-T). The treatments will be 4 x 25 mg BI 1358894 film-coated tablet in 
the fed state (T) and four placebo film-coated tablets in the fed state (R) administered prior to
CCK-4 injection. For this trial CCK-4 will be used as a provoking agent. For details refer to 
Section 4.1.
There will be a washout period of at least 17 days between the treatments.
An overview of all relevant trial activities is provided in the Flow Chart. For visit schedule 
and details of trial procedures at selected visits, refer to Sections 6.1 and 6.2, respectively.
3.2
DISCUSSION OF TRIAL DESIGN, INCLUDING THE CHOICE OF 
CONTROL GROUP(S)
For experimental challenge studies, the crossover design is preferred due to its efficiency: 
since each subject serves as his own control, the comparison between treatments is based on a 
comparison within subjects rather than between subjects. This trial design therefore removes 
intersubjective variability from the comparison between treatments and the overall number of 
subjects enrolled can be minimized [R94-1529].
3.3
SELECTION OF TRIAL POPULATION
It is planned that 20 healthy male subjects will enter the study; a minimum of 15 subjects 
must be evaluable for the analysis of the primary endpoint (see Section 3.3.5 for replacement 
of subjects). They will be recruited from the volunteers' pool of the trial site. For the selection 
of the 20 healthy male subjects it is planned to screen up to about 60 healthy male subjects to 
identify 20 CCK-4 sensitive subjects by exposing them to a CCK-4 challenge during 
Screening. Sufficient CCK-4 sensitivity is defined as achievement of the following after a 
CCK-4 i.v. bolus injection:

A sudden onset of panic and

Presence of at least 4 symptoms in the PSS and

A score of 2 or higher on PSS item 15: “Anxiety and Fear for Apprehension” 
Or: 

Achievement of a total PSS sum intensity score > 20 after CCK-4 i.v. bolus injection.
Only male subjects will be included in the study because limited data on reproductive 
toxicology are available at this time.
A log of all subjects enrolled into the trial (i.e. who have signed informed consent) will be 
maintained in the ISF irrespective of whether they have been treated with investigational drug 
or not.

For study restrictions, refer to Section 4.2.2.
3.3.4
Withdrawal of subjects from treatment or assessments
Subjects may discontinue trial treatment or withdraw consent to trial participation as a whole 
(‘withdrawal of consent’) with very different implications; please see Sections 3.3.4.1 and 
3.3.4.2 below.
If a subject is removed from or withdraws from the trial prior to the first administration of 
trial medication, the data of this subject will not be entered in the case report form (CRF) and 
will not be reported in the clinical trial report (CTR). If a subject is removed from or 
withdraws from the trial after the first administration of trial medication, this will be 
documented and the reason for discontinuation must be recorded in the CRF; in addition, the 
data will be included in the CRF and will be reported in the CTR. At the time of 
discontinuation, a complete end of trial examination will be performed, if possible, and the 
information will be recorded in the CRF. If the discontinuation occurs before the end of the 
REP (see Section 1.2.3), the discontinued subject should if possible be questioned for AEs 
and concomitant therapies at or after the end of the REP in order to ensure collection of AEs 
and concomitant therapies throughout the REP, if not contrary to any consent withdrawal of 
the subject.
3.3.4.1
Discontinuation of trial treatment
An individual subject will discontinue trial treatment if:
1. The subject wants to discontinue trial treatment, without the need to justify the decision
2. The subject has repeatedly shown to be non-compliant with important trial procedures 
and, in the opinion of both, the investigator and sponsor representative, is not willing or 
able to adhere to the trial requirements in the future
3. The subject needs to take concomitant medication that interferes with the investigational 
medicinal product or other trial treatment
4. The subject can no longer receive trial treatment for medical reasons (such as surgery, 
adverse events [AEs], or diseases)
5. An AE or clinically significant laboratory change or abnormality occurred that the 
investigator judges to warrant discontinuation of treatment. This may include cases of 
sustained symptomatic hypotension (BP <90/50 mmHg) or hypertension (BP >180/100 
mmHg) or of clinically relevant changes in ECG requiring intervention as well as 
unexplained liver enzyme elevations at any time during the trial

6. The subject has an elevation of AST and/or ALT ≥3-fold ULN and an elevation of total 
bilirubin ≥2-fold ULN (measured in the same blood sample) and/or needs to be followed 
up according to the DILI checklist provided in the ISF
7. The subject shows a raised CRP level of >3.00 mg/dL or an ESR of ≥20 millimeters/hour
if these results are confirmed by a second sample.
In addition to these criteria, the investigator may discontinue subjects at any time based on 
his or her clinical judgment.
Even if the trial treatment is discontinued, the subject remains in the trial and, given his 
agreement, will undergo the procedures for early treatment discontinuation and follow up as 
outlined in the Flow Chart and Section 6.2.3.
3.3.4.2
Withdrawal of consent to trial participation
Subjects may withdraw their consent to trial participation at any time without the need to 
justify the decision. If a subject wants to withdraw consent, the investigator should be 
involved in the discussion with the subject and explain the difference between trial treatment 
discontinuation and withdrawal of consent to trial participation, as well as explain the options 
for continued follow up after trial treatment discontinuation, please see Section 3.3.4.1 above
3.3.4.3
Discontinuation of the trial by the sponsor
Boehringer Ingelheim reserves the right to discontinue the trial at any time for any of the 
following reasons:
1. Failure to meet expected enrolment goals 
2. New toxicological findings, serious adverse events, or any safety information invalidating
the earlier positive benefit-risk-assessment. More specifically, the trial will be terminated 
if more than 50% of the subjects have drug-related and clinically relevant adverse events 
of moderate or severe intensity, or if at least 1 drug-related serious adverse event is 
reported
3. Violation of GCP, or the CTP, or the contract with BI, impairing the appropriate conduct 
of the trial
4. The sponsor decides to discontinue the further development of the investigational product
5. The trial will be stopped if at least 2 subjects show relevant individual QT prolongation 
(absolute QT or QTc greater than 500 ms), which has been confirmed by a repeat ECG 
recording
6. Occurrence of severe non-serious adverse events considered as drug-related by the 
investigator in 2 subjects of the same dose group
The investigator / trial site will be reimbursed for reasonable expenses incurred in case of 
trial termination (except if item 3 applies).
3.3.5
Replacement of subjects
In case some subjects do not complete the trial, the Clinical Trial Leader together with the 
Trial Pharmacokineticist and the Trial Statistician are to decide, if and how many subjects

Selection of doses in the trial
The CCK-4 dose selected for this trial reflects standard doses for clinical trials (see 
Section 1.2). The administration of 50 μg CCK-4 has been performed in numerous clinical 
research trials in healthy subjects, elderly subjects, and patients with anxiety disorders. It has 
proven to be well-tolerated, even in patients with anxiety disorders who are highly sensitive 
to such challenges [P98-0035], [R18-2694], [R18-2695], [R18-2696].
In this single dose CCK-4 challenge study a higher inhibition of about 90 % (EC90) is 
intended to be achieved during PSS evaluation in order to ensure adequate target inhibition 
during the short lasting CCK-4 related stimulus.

4.1.3
Method of assigning subjects to treatment groups
Prior to start of the study, subjects willing to participate will be recruited to cohorts according 
to their temporal availability. According to the planned sample size, at least 4 cohorts are 
planned. After assessment of all in- and exclusion criteria, each eligible patient will be 
randomised to treatment groups in the morning of Day 1 (Visit 2) prior to first administration 
of trial medication and the appropriate medication number will be assigned. The
randomisation will be provided by the sponsor to the trial site in advance.
Once a subject number has been assigned, it cannot be reassigned to any other subject.
Subject Numbers are automatically pre-populated via the BRAVE system (during data entry, 
in an ascending order).
The randomisation procedure is described in Section 7.6.
4.1.4
Drug assignment and administration of doses for each subject
This trial is a 2-way crossover study. All subjects will receive the 2 treatments in randomised 
order. The treatments to be evaluated are outlined in Table 4.1.4: 1 below.

The investigator (or authorised designee) will administer the trial medication as a single oral 
dose together with about 240 mL of water to subjects who are in a sitting position. For drug 
administration, the so-called four-eye principle (two-person rule) should be applied. For this, 
one authorised employee of the trial site should witness the administration of trial medication, 
and – if applicable – its preparation (e.g. reconstitution), if correct dosage cannot be ensured 
otherwise.
CCK-4 will be provided in vials containing 50 μg lyophilized CCK-4. Immediately prior to 
use, 5 mL of sterile normal saline (0.9% NaCl) for injection will be added to the vial 
containing lyophilized CCK-4 powder and mixed to produce a solution for injection. Before 
CCK-4 administration, 5 mL (50 μg CCK-4) of the solution is withdrawn from the vial into a 
syringe. Then the CCK-4 will be administered to the subjects as a bolus injection over 5 
seconds (maximum of 8 seconds) via a venous cannula.
In each treatment period, a high-fat, high-calorie meal will be served 30 min before BI drug 
administration. The subjects must completely consume the meal prior to drug intake. The 
composition of the standard high-fat, high-calorie meal is detailed in Table 4.1.4: 2; this meal 
is in compliance with the FDA guidance ‘Food-Effect Bioavailability and Fed 
Bioequivalence Studies’ [R03-2269]. For restrictions with regard to diet, see Section 4.2.2.2.

Subjects will be kept under close medical surveillance for 8 days after drug administration as 
described in the Flow Chart.
During the first 2 h after drug administration, subjects will only be allowed to lie down if 
supine positioning is required for trial-related measurements (e.g. recording of 12-lead ECG).
The treatments will be separated by a wash-out phase of at least 17 days.
4.1.5
Blinding and procedures for unblinding
The trial is designed double-blind. Neither subject nor investigator will be aware of the trial 
treatments. The investigator will be supplied with a set of sealed envelopes containing the 
medication codes. The envelopes will be kept unopened at the study site until the end of data 
collection or, in an emergency requiring the investigator to know a subject’s treatment 
allocation, opened with appropriate documentation. At the trial close-out visit, all envelopes 
will be collected.
Access to the randomisation schedule is restricted to the randomisation operators, the Clinical 
Trial Support group and the Pharmaceutics Department. 
Persons directly involved in the conduct of the trial will be blinded to trial treatments. The 
trial medication will be packed blinded. The trial will only be unblinded after locking of the 
database, which takes place only after the trial is clinically completed and all queries have 
been clarified. Access to the randomisation codes will be controlled and documented by a 
signed confidentiality statement, which will be stored in the TMF.
Regarding the sponsor, the database of this trial will be handled open-label, meaning that the 
trial functions of the sponsor are unblinded (including clinical monitor, data manager, 
statistician, bioanalyst, pharmacokineticist, pharmacometrician, drug metabolism scientist as 
well as dedicated CRO personnel). The objective of the trial is not expected to be affected.

Electrocardiogram
5.2.4.1
Twelve-lead ECGs
Twelve-lead ECGs (I, II, III, aVR, aVL, aVF, V1 - V6) will be recorded using a 
computerised electrocardiograph (e.g. Mortara Eli 250 C) at the times provided in the 
Flow Chart.
To achieve a stable heart rate at rest and to assure high quality recordings, the site personnel 
will be instructed to assure a relaxed and quiet environment, so that all subjects are at 
complete rest.
All ECGs will be recorded for a 10 sec duration after subjects have rested for at least 5 min in 
a supine position. ECG assessment will always precede all other study procedures scheduled 
for the same time to avoid compromising ECG quality. 
All ECGs will be stored electronically. 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. Abnormal 
findings will be reported as AEs (during the trial) or baseline conditions (at screening) if 
assessed to be clinically relevant by the investigator. Any ECG abnormalities will be 
carefully monitored and, if necessary, the subject will be removed from the trial and will 
receive the appropriate medical treatment. 
ECGs may be repeated for quality reasons (for instance, due to alternating current artefacts, 
muscle movements, or electrode dislocation) and the repeated ECG will be used for analysis. 
Additional (unscheduled) ECGs may be collected by the investigator for safety reasons. 
5.2.4.2
Continuous ECG monitoring
Cardiac rhythm (including heart rate) will be monitored by means of continuous 12-lead ECG 
recording at visit 2 for at least 15 min before CCK-4 challenge until 30 min after the 
challenge and at visit 3 and 4 for at least 2 h before the BI 1358894 administration (for 
baseline assessment), and 6 h following drug administration using patient monitors (e.g. 
Mortara Telemetry System). Abnormal findings will be recorded as AEs if judged clinically 
relevant by the Investigator but no other data will be transferred to the database.

SSRS is a brief measure which is designed to assess severity and change of suicidality by 
integrating both, behaviour and ideation. The C-SSRS was designed to address the need for a 
summary measure to track change in the severity of suicidality across both clinical settings 
and treatment trials.
The original English version is shown in Appendix 10.2.
5.2.6
Assessment of adverse events
5.2.6.1
Definitions of adverse events
Adverse event
5.2.6.1.1
An adverse event (AE) is defined as any untoward medical occurrence in a patient or clinical 
investigation subject administered a medicinal product and which does not necessarily have 
to have a causal relationship with this treatment.
An AE can therefore be any unfavourable and unintended sign (including an abnormal 
laboratory finding), symptom, or disease temporally associated with the use of a medicinal 
product, whether or not considered related to the medicinal product.
The following should also be recorded as an AE in the CRF and BI SAE form (if applicable):

Worsening of the underlying disease or of other pre-existing conditions 

Changes in vital signs, ECG, physical examination, and laboratory test results, if they 
are judged clinically relevant by the investigator
If such abnormalities already pre-exist prior to trial inclusion, they will be considered as 
baseline conditions and should be collected in the eCRF only.
The provoked panic symptoms in response to CCK-4 injection (as documented by the PSS 
score), which are prerequisite for demonstrating a potential effect of the investigational 
compound, will be considered PD parameters. Since they are an expected and desired 
response in the context of this trial (even though they constitute an untoward medical 
occurrence), they will not be recorded as AEs. All other observations not included on the PSS 
questionnaire occurring during the standard AE reporting time period (see Section 5.2.6.2.1) 
are to be documented as AEs.
Serious adverse event
5.2.6.1.2
A serious adverse event (SAE) is defined as any AE which fulfils at least one of the 
following criteria:

Results in death 

Is life-threatening, which refers to an event in which the patient was at risk of death 
at the time of the event; it does not refer to an event that hypothetically might have 
caused death if more severe 

Requires inpatient hospitalisation


Requires prolongation of existing hospitalisation

Results in persistent or significant disability or incapacity 

Is a congenital anomaly/birth defect 

Is deemed serious for any other reason if it is an important medical event when based 
upon appropriate medical judgment which may jeopardise the patient and may 
require medical or surgical intervention to prevent one of the other outcomes listed in 
the above definitions. Examples of such events are intensive treatment in an 
emergency room or at home for allergic bronchospasm, blood dyscrasias or 
convulsions that do not result in hospitalisation or development of dependency or 
abuse
AEs considered ‘Always Serious’
5.2.6.1.3
Cancers of new histology and exacerbations of existing cancer must be classified as a serious 
event regardless of the time since discontinuation of the trial medication and must be reported 
as described in Section 5.2.6.2, subsections ‘AE Collection’ and ‘AE reporting to sponsor 
and timelines’.
In accordance with the European Medicines Agency initiative on Important Medical Events, 
Boehringer Ingelheim has set up a list of further AEs, which, by their nature, can always be 
considered to be ‘serious’ even though they may not have met the criteria of an SAE as 
defined above.
The latest list of ‘Always Serious AEs’ can be found in the eDC system, an electronic data 
capture system which allows the entry of trial data at the trial site. These events should 
always be reported as SAEs as described above.
5.2.6.1.4
Detailed assessment of the adverse advent headache
If the subject reports headaches during the treatment period, the following information and 
data should be collected daily until the headache is resolved:

Onset after medication intake (hhh:min)

Headache severity on a Numeric Ranking Scale (NRS) ranging from 0 - 10

Quality of headache (new type of headache vs. similar to previous experienced 
episodes of known headaches)

Headache characteristics (pressing or tightening vs. burning vs. pulsating vs. 
aggravated by routine physical activity (such as walking or climbing stairs))

Location (all of the following that apply: unilateral, bilateral, holocephal, frontal, 
temporal, occipital, facial)

Any accompanying symptoms like all of the following that apply: nausea and/or 
vomiting, photophobia, phonophobia, lacrimation, other

If headache is resolved: overall duration of headache episode (start time and end time)

5.2.6.1.5
Suicidal risk assessed by the C-SSRS (paper version)
The C-SSRS is a semi-structured, investigator-rated interview, developed by clinical experts 
in cooperation with the FDA, assessing both suicidal behavior and suicidal ideation. It does 
not give a global score, but provides some categorical and some severity information 
specifically for behavior and ideation.
The C-SSRS interview may be administered by any type of physician, psychologist, clinical 
social worker, mental health counselor, nurse, or coordinator with C-SSRS training. It has a 
typical duration of five minutes, and causes only a low burden on subjects. At a minimum, 
the interview consists of 2 screening questions related to suicidal ideation and 4 related to 
suicidal behavior, and may be expanded to up to 17 items in case of positive responses. Free 
text entries are allowed for; the investigator has to directly evaluate the scale and write a 
report.
The C-SSRS has been widely used in large multinational clinical trials. The C-SSRS will be 
administered at the screening visit (using the ‘screening / baseline’ version) with the aim to 
exclude subjects with active moderate or severe symptomatology within a specified time 
prior to the screening or baseline visit. The life time history of suicidal ideation and behavior 
will also be recorded.
After the baseline visit, the assessment ‘since last visit’ will be performed at each clinic or 
phone visit (‘since last visit’ version). The investigator is to review positive and negative 
reports for plausibility and clinical relevance. Doubtful reports may be repeated or reports 
may be validated by a consulting psychiatrist. If there is a confirmed positive report of 
suicidal behavior or suicidal ideation type 4 or 5 after start of trial, the investigator is to 
immediately interview the subject during the clinic visit, and/or is to consult a psychiatrist. If 
the positive report is confirmed, appropriate actions for the subject’s safety have to be 
initiated.
All C-SSRS reports of suicidal ideation type 4 or 5 and all reports of suicidal behavior must 
be reported as separate SAEs by the investigator.
For ‘Self-injurious behaviour, no suicidal intent’ (Type 11) standard AE / SAE reporting 
rules are to be applied.
For each negative report (suicidal ideation type 1, 2 or 3) after start of the trial, the
investigator is to decide based on clinical judgment whether it represents an adverse event 
(AE) as defined in the protocol, and if it is considered an AE then it must be reported 
accordingly.

5.2.6.1.6
Adverse events of special interest
The term adverse events of special interest (AESI) relates to any specific AE that has been 
identified at the project level as being of particular concern for prospective safety monitoring 
and safety assessment within this trial, e.g. the potential for AEs based on knowledge from 
other compounds in the same class. AESIs need to be reported to the sponsor’s 
Pharmacovigilance Department within the same timeframe that applies to SAEs, please see 
Section 5.2.6.2.2.
The following is considered an AESI:

Hepatic injury
A hepatic injury is defined by the following alterations of hepatic laboratory 
parameters: 
o
An elevation of AST (aspartate transaminase) and/or ALT (alanine 
transaminase) ≥3-fold ULN combined with an elevation of total bilirubin 
≥2-fold ULN measured in the same blood sample, or
o
Aminotransferase (ALT, and/or AST) elevations ≥10 fold ULN
These lab findings constitute a hepatic injury alert and the subjects showing these lab
abnormalities need to be followed up according to the ‘DILI checklist’ provided in the 
ISF. In case of clinical symptoms of hepatic injury (icterus, unexplained 
encephalopathy, unexplained coagulopathy, right upper quadrant abdominal pain, 
etc.) without lab results (ALT, AST, total bilirubin) available, the Investigator should 
make sure that these parameters are analysed, if necessary in an unscheduled blood 
test. Should the results meet the criteria of hepatic injury alert, the procedures 
described in the DILI checklist should be followed.
5.2.6.1.7
Intensity (severity) of AEs
The intensity (severity) of the AE should be judged based on the following:
Mild:
Awareness of sign(s) or symptom(s) that is/are easily tolerated
Moderate:
Sufficient discomfort to cause interference with usual activity
Severe:
Incapacitating or causing inability to work or to perform usual activities
5.2.6.1.8
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 reduced)
Arguments that may suggest that there is no reasonable possibility of a causal relationship 
could be:

No plausible time to onset of the event relative to the time of drug exposure is evident 
(e.g. pre-treatment cases, diagnosis of cancer or chronic disease within days / weeks 
of drug administration; an allergic reaction weeks after discontinuation of the drug 
concerned)

Continuation of the event despite the withdrawal of the medication, taking into 
account the pharmacological properties of the compound (e.g. after 5 half-lives). Of 
note, this criterion may not be applicable to events whose time course is prolonged 
despite removing the original trigger

Additional arguments amongst those stated before, like alternative explanation (e.g. 
situations where other drugs or underlying diseases appear to provide a more likely 
explanation for the observed event than the drug concerned)

Disappearance of the event even though the trial drug treatment continues or remains 
unchanged
5.2.6.2
Adverse event collection and reporting
AE collection
5.2.6.2.1
Upon enrolment into a trial, the subject’s baseline condition is assessed (for instance, by 
documentation of medical history/concomitant diagnoses), and relevant changes from 
baseline are noted subsequently. 
Subjects will be required to report spontaneously any AEs as well as the time of onset, end
time, and intensity of these events. In addition, each subject will be regularly assessed by the 
medical staff throughout the clinical trial and whenever the investigator deems necessary. As 
a minimum, subjects will be questioned for AEs (and concomitant therapies) at the time 
points indicated in the Flow Chart. Assessment will be made using non-specific questions 
such as ‘How do you feel?’. Specific questions will be asked wherever necessary in order to 
more precisely describe an AE.
A carefully written record of all AEs shall be kept by the investigator in charge of the trial. 
Records of AEs shall include data on the time of onset, end time, intensity of the event, and 
any treatment or action required for the event and its outcome.
The following must be collected and documented on the appropriate CRF(s) by the 
investigator:

From signing the informed consent onwards until an individual subject’s end of trial:

o
All AEs (serious and non-serious) and all AESIs 
o
The only exception to this rule are AEs (serious and non-serious) and AESIs 
in Phase I trials in healthy volunteers, when subjects discontinue from the trial 
due to screening failures prior to administration of any trial medication. In 
these cases, the subjects’ data must be collected at trial site but will not be 
entered in the CRF or trial database and will not be reported in the CTR.

After the individual subject’s end of trial: 
o
The investigator does not need to actively monitor the subject for AEs but 
should only report any occurrence of cancer and related SAEs and related 
AESIs of which the investigator may become aware of by any means of 
communication, e.g. phone call. Those AEs should, however, not be reported 
in the CRF.
AE reporting to the sponsor and timelines
5.2.6.2.2
The Investigator must report SAEs, AESIs, and non-serious AEs which are relevant for the 
reported SAE or AESI, on the BI SAE form via fax immediately (within 24 hours) to the 
sponsor’s unique entry point (country specific contact details will be provided in the ISF). 
The same timeline applies if follow-up information becomes available. In specific occasions 
the Investigator could inform the sponsor upfront via telephone. This does not replace the 
requirement to complete and fax the BI SAE form. 
With receipt of any further information to these events, a follow-up SAE form has to be 
provided. For follow-up information, the same rules and timeline apply as for initial 
information.
Information required
5.2.6.2.3
All (S)AEs, including those persisting after the individual subject’s end of trial, must be 
followed up until they have resolved, have been sufficiently assessed as ‘chronic’ or ‘stable’, 
or no further information can be obtained.
Pregnancy
5.2.6.2.4
Once a male subject has been enrolled in the clinical trial and has taken trial medication, and 
if the partner of the male trial participant becomes pregnant, the investigator must report any 
drug exposure during pregnancy in a partner of the male trial participant immediately (within 
24 hours) by means of Part A of the Pregnancy Monitoring Form to the sponsor’s unique 
entry point, after a written consent of the pregnant partner.
The outcome of the pregnancy associated with the drug exposure during pregnancy must be 
followed up and reported to the sponsor’s unique entry point on the Pregnancy Monitoring 
Form for Clinical Trials (Part B).
The ISF will contain the Pregnancy Monitoring Form for Clinical Trials (Part A and Part B) 
as well as non-trial specific information and consent for the pregnant partner.
As pregnancy itself is not to be reported as an AE, in the absence of an accompanying SAE 
and/or AESI, only the Pregnancy Monitoring Form for Clinical Trials and not the SAE form

PSS:
The PSS is a patient reported outcome measurement from which the following factors are 
derived: physical symptoms of fear and the perception of alertness, anxiety, fear, and pain. 
The PSS assessments conducted on Day 1 15 min before drug administration will be 
considered as period baseline. At each measuring time point indicated in the Flow Chart, the 
subjects will assess their subjective impression of themselves by means of the panic symptom 
scale. The subjects will be asked to mark an adequate position on a scale from 0 (absent) to 4 
(very strong) of the characteristic 18 questions to be measured. The sum of the scale over all 
items will constitute the PSS sum intensity score. In addition to this sum intensity score, the 
number of positively rated PSS symptoms (total number of symptoms) will be also recorded. 
The score will be documented in the electronic case report form. It is anticipated that the 
highest PSS sum intensity score will be reached approximately 5 minutes after CCK-4
injection and will decrease thereafter.

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. The biomarkers and 
pharmacodynamic parameters and measurements outlined in Sections 5.5 and 5.6 are of

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 the end of trial examination are provided in the 
Flow Chart.
Study measurements and assessments scheduled to occur ‘before’ trial medication 
administration on Day 1 are to be performed and completed within a 3 h-period prior to the 
trial drug administration.
The acceptable deviation from the scheduled time for vital signs, ECG, and laboratory tests 
will be ± 30 min.
Study measurements and assessments scheduled to occur at ambulatory visits as indicated in 
the Flow Chart are to be performed and completed within a 3 h-period latest at 11:30 a.m.
If scheduled in the Flow Chart at the same time as a meal, blood sampling, vital signs, and 
12-lead ECG recordings have to be done first. Furthermore, if several measurements 
including venepuncture are scheduled for the same time, venepuncture should be the last of 
the measurements due to its inconvenience to the subject and possible influence on 
physiological parameters.
For planned blood sampling times, refer to the Flow Chart. While these nominal times should 
be adhered to as closely as possible, the actual sampling times will be recorded and used for 
the determination of pharmacokinetic parameters.
If a subject misses an appointment, it will be rescheduled if possible. The relevance of 
measurements outside the permitted time windows will be assessed no later than at the 
Blinded Report Planning Meeting.
6.2

On Day -1 of each treatment period, study participants will be admitted to the trial site and 
kept under close medical surveillance for 8 days after drug administration. On Day 9, the 
subjects will then be allowed to leave the trial site after formal assessment and confirmation 
of their fitness. On all other study days, subjects will be treated in an ambulatory fashion.
For details on time points and procedures for collection of plasma samples for PK analysis, 
refer to Flow Chart and Section 5.3.2.
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 times of 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
Follow-up period and trial completion
For AE assessment, laboratory tests, recording of ECG and vital signs, and physical 
examination during the follow-up period, see Sections 5.2.2 to 5.2.6.
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 assessed as 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 a subject’s end of trial visit must be 
followed until they have resolved, have been sufficiently characterised, or no further 
information can be obtained.

STATISTICAL METHODS AND DETERMINATION OF
SAMPLE SIZE
7.1
STATISTICAL DESIGN – MODEL
This is a double-blind, randomised, two-way cross-over, single-dose trial, including a 
washout period of at least 17 days between the treatments (Section 3.1).
The main objective of this trial is to investigate the pharmacodynamic effects of a single dose 
of BI 1358894 (Test, T) on CCK-4 induced anxiogenic/ panic-like symptoms using the PSS 
compared to placebo (Reference, R) on the basis of the primary pharmacodynamic endpoint
as listed in Section 2.1.2. The trial is designed to allow intra-subject comparisons and will be 
evaluated statistically by use of a linear mixed effects model.
The assessment of safety and tolerability is a further objective of this trial, and will be 
evaluated by descriptive statistics for the parameters specified in Section 2.2.2.2.
7.2
NULL AND ALTERNATIVE HYPOTHESES
It is not planned to test any statistical hypotheses with regard to any of the variables listed in 
Section 2 in a confirmatory sense. Two sided 90% confidence intervals (CIs) will be 
computed and will have to be interpreted in the perspective of the exploratory character of the 
study.
7.3
PLANNED ANALYSES
Analysis sets

Pharmacodynamics
PSS data of a subject will be included in the statistical analysis if they are not flagged for 
exclusion. Reasons for exclusion of single PSS parameters may be:

The subject experiences emesis at or before two times median tmax or before the 
subject completes PSS assessments on study day 1 according to Flow Chart. Median 
tmax is to be determined excluding the subjects experiencing emesis 

Time deviations

Use of restricted medications 

If a predose concentration value is greater than 5% of Cmax of the subjects´ 
pharmacokinetic data, the respective PD assessments in the respective period may be 
excluded from statistical assessments
7.3.1
Primary endpoint analyses
The derivation of the primary endpoint PSS sum intensity score per time point is outlined in 
Section 5.6.3. The maximum CfB is defined as the maximum of the differences of the PSS 
sum intensity score measured at each time point after the CCK-4 challenge minus the PSS 
sum intensity score measured at baseline. Further details on the calculation will be given in 
the TSAP. The primary endpoint analysis will be performed on the PDS (refer to 
Section 7.3).
Primary analyses
The statistical model used for the investigation of the primary endpoint PSS sum intensity 
score will be a mixed effects model given by

the two period baseline values is considered as the subject baseline.
The treatment comparison will be the difference between active treatment and placebo. 
Adjusted means (Least Squares Means) as well as 2-sided 90% CIs will be calculated.
Additionally, the difference in adjusted means relative to placebo will be provided. To 
support this analysis, listings and graphical displays may be generated if appropriate. 
As a sensitivity analysis, the same statistical model as stated above will be repeated for the 
primary endpoint but with all sources of variation considered as fixed effects.
Further details will be presented in the TSAP.

7.3.4
Safety analyses
Safety will be analysed based on the assessments described in Section 2.2.2.2. All treated 
subjects (TS, refer to Section 7.3) will be included in the safety analysis. Safety analyses will 
be descriptive in nature and based on BI standards. No hypothesis testing is planned.
For all analyses, the treatment actually administered (= treatment at onset) to the subject will 
be used (any deviations from the randomised treatment will be discussed in the minutes of the 
Blinded Report Planning Meeting).
Treatments will be compared in a descriptive way. Tabulations of frequencies/proportions 
will be used to evaluate categorical (qualitative) data, and tabulations of descriptive statistics 
will be used to analyse continuous (quantitative) data.
Measurements (such as ECG, vital signs, or laboratory parameters) or AEs will be assigned to 
treatments (see Section 4.1) based on the actual treatment at the planned time of the 
measurement or on the recorded time of AE onset (concept of treatment emergent AEs).
Therefore, measurements planned or AEs recorded prior to first intake of trial medication will 
be assigned to the screening period, those between first trial medication intake and end of 
REP (see Section 1.2.3) will be assigned to the treatment period. Events occurring after the 
REP but prior to next intake or end of trial termination date will be assigned to ’follow-up’. 
In case of two or more treatments, the follow-up will be summarized according to the 
immediately preceding treatment. These assignments including the corresponding time 
intervals will be defined in detail in the TSAP. Note that AEs occurring after the last per 
protocol contact but entered before final database lock will be reported to Pharmacovigilance
only and will not be captured in the trial database.
Additionally, further treatment intervals (analysing treatments) may be defined in the TSAP 
in order to provide summary statistics for time intervals, such as combined treatments, on-
treatment totals, or periods without treatment effects (such as screening and follow-up 
intervals).
Adverse events will be coded using the Medical Dictionary for Regulatory Activities 
(MedDRA). Frequency, severity, and causal relationship of AEs will be tabulated by 
treatment, system organ class, and preferred term. SAEs, AESIs (see Section 5.2.6.1), and 
other significant AEs (according to ICH E3) will be listed separately.
Previous and concomitant therapies will be presented per treatment group without 
consideration of time intervals and treatment periods.
Laboratory data will be compared to their reference ranges. Values outside the reference 
range as well as values defined as possibly clinically significant will be highlighted in the 
listings. Additionally, differences from baseline will be evaluated.
Vital signs or other safety-relevant data will be assessed with regard to possible on-treatment 
changes from baseline.
Relevant ECG findings will be reported as AEs.

Pharmacokinetic and pharmacodynamic analyses
For a description of PK and PD analyses, please see Section 7.3.1 and Section 7.3.3.
7.4
INTERIM ANALYSES
No interim analysis is planned.
7.5
HANDLING OF MISSING DATA
7.5.1
Safety
It is not planned to impute missing values for safety parameters.
7.5.2
Pharmacokinetics
Handling of missing PK data will be performed according to the relevant Corporate 
Procedure [001-MCS-36-472].
PK parameters that cannot be reasonably calculated based on the available drug 
concentration-time data will not be imputed.
7.5.3
Pharmacodynamics
For the PD endpoints PSS 
 if the period baseline value is missing in treatment 
period 1, it will be imputed by the corresponding value measured in treatment period 2. If the 
period baseline value is missing in treatment period 2, it will be imputed by the 
corresponding value measured in treatment period 1. If a value is missing after CCK-4
injection, this value will not be imputed. If all four assessments after CCK-4 injection are 
missing for a subject, this subject is not evaluable for this endpoint in this period.
7.6
RANDOMISATION
Subjects will be randomised to one of the 2 treatment sequences in a 1:1 ratio. The block size 
will be documented in the CTR.
The sponsor will arrange for the randomisation as well as packaging and labelling of trial 
medication. The randomisation list will be generated using a validated system that uses a 
pseudo-random number generator and a supplied seed number so that the resulting allocation 
is both reproducible and non-predictable. Access to the codes will be controlled and 
documented.
The randomisation list will contain additional blocks to allow for subject replacement (refer 
to Section 3.3.5).

7.7
DETERMINATION OF SAMPLE SIZE
It is planned to enter a total of 20 subjects in the trial, because this sample size is considered
sufficient to achieve the aims of this exploratory trial. At least 15 subjects need to be 
evaluable for the primary objective of this trial.
Based on this sample size, the probability to observe a meaningful reduction in PSS sum 
intensity score after a single dose of BI 1358894 when compared to placebo is given in 
Table 7.7: 1 for N=20 subjects and in Table 7.7: 2 for N=15 subjects.
For these calculations, the following assumptions are made. A total of N subjects are 
evaluable in this cross-over study. The standard deviation of the maximum change from 
baseline of the treatment contrast of PSS relative to placebo is 20%. The maximum change 
from baseline for PSS sum intensity score relative to placebo is 0% after the placebo 
treatment. Six different scenarios are displayed.

Probability to observe a difference in the primary endpoint ≤ 20%, 
20% - 40% and > 40% relative to placebo for different scenarios and 
a sample size of N=20 evaluable subjects.

8.2
DATA QUALITY ASSURANCE
A risk-based approach is used for trial quality management. It is initiated by the assessment 
of critical data and processes for trial subject protection and reliability of the results as well as 
identification and assessment of associated risks. An Integrated Quality and Risk 
Management Plan documents the rationale and strategies for risk management during trial 
conduct including monitoring approaches, vendor management and other processes focusing 
on areas of greatest risk. 
Continuous risk review and assessment may lead to adjustments in trial conduct, trial design 
or monitoring approaches. 
A quality assurance audit/inspection of this trial may be conducted by the sponsor, sponsor’s 
designees, or by IRB / IEC or by regulatory authorities. The quality assurance auditor will 
have access to all medical records, the investigator’s trial-related files and correspondence, 
and the informed consent documentation of this clinical trial.
8.3
RECORDS
CRFs for individual subjects will be provided by the sponsor. See Section 4.1.5 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 for each trial subject that include 
all observations and other data pertinent to the investigation. Source data as well as reported 
data should follow the ‘ALCOA principles’ 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.
Before providing any copy of subjects’ source documents to the sponsor, the investigator 
must ensure that all subject identifiers (e.g., subject’s name, initials, address, phone number, 
and social security number) have properly been removed or redacted to ensure subject 
confidentiality.
If the subject is not compliant with the protocol, any corrective action (e.g. re-training) must 
be documented in the subject file.
For the CRF, data must be derived from source documents, for example:

Subject identification: sex, year of birth (in accordance with local laws and 
regulations)

Subject participation in the trial (substance, trial number, subject number, date subject 
was informed)

Dates of subject’s visits, including dispensing of trial medication

INTRODUCTION
As per ICH E9 (1), the purpose of this document is to provide a more technical and detailed 
elaboration of the principal features of the analysis described in the protocol, and to include 
detailed procedures for executing the statistical analysis of the primary and secondary 
variables and other data.
This TSAP assumes familiarity with the Clinical Trial Protocol (CTP), including Protocol 
Amendments. In particular, the TSAP is based on the planned analysis specification as 
written in CTP Section 7 “Statistical Methods and Determination of Sample Size”. Therefore, 
TSAP readers may consult the CTP for more background information on the study, e.g., on 
study objectives, study design and population, treatments, definition of measurements and 
variables, planning of sample size, randomization.
Study data (including data entered in the RAVE EDC system and external data provided by 
suppliers) will be stored in a Clinical Data Repository (CDR).
The statistical analyses will be performed within the validated working environment CARE, 
including SASTM (current Version 9.4, by SAS Institute Inc., Cary, NC, USA), and a number 
of SASTM-based tools (e.g., macros for the analyses of AE data or laboratory data; Report 
Appendix Generator system (RAGe) for compilation/formatting of the CTR appendices). 
PK parameters will be calculated by means of noncompartmental analysis using Phoenix 
WinNonlinTM software (current version Phoenix 6.3 or higher, Certara USA Inc., Princeton, 
NJ, USA). Outputs for the CTR will be generated using SASTM (current Version 9.4, by SAS 
Institute Inc., Cary, NC, USA).

CHANGES IN THE PLANNED ANALYSIS OF THE STUDY
All analyses as planned in the CTP will be performed and are described in more detail in this 
TSAP.
The following changes compared to the protocol will be made:
No ‘Enrolled set (ES)’ will be defined in the TSAP as data of subjects discontinued before 
first administration of investigational trial medication will not be entered in the CDR. A 
correct display of the ES is therefore not possible. Due to the same reason, the ‘Entered set 
(ENTS)’ will be similar to the ‘Treated set (TS)’. Therefore, no ‘Entered set (ES)’ will be 
defined in the TSAP as well.

Safety and Tolerability endpoints
Safety and tolerability of BI 1358894 will be assessed based on parameters defined in 
Section 2.2.2.2 and Section 2.2.2.3 of the CTP:

Adverse events (including clinically relevant findings from the physical and 
neurological examinations)

Safety laboratory tests

12-lead ECG

Continuous ECG monitoring

Vital signs (blood pressure, pulse rate)

Suicidality assessment (C-SSRS)
Local tolerability of CCK-4 injections (absence or presence of "swelling", "induration", 
"heat", "redness", "pain", or "other findings") will be summarized with counts and 
percentages overall (i.e. subject-wise worst case over all injections and time points) as well as
listed by injection and time point.

GENERAL ANALYSIS DEFINITIONS
6.1
TREATMENTS
For basic study information on treatments to be administered, assignment of treatment 
groups, and selection of doses, cf. Section 4 of the CTP.
Each subject is planned to be treated in two subsequent treatment periods, with one single 
dose of BI 1358894 or placebo in each treatment period:

Test treatment (Treatment T):
4 x 25 mg BI 1358894 film-coated tablet in the fed state

Reference treatment (Treatment R):
4 x placebo film-coated tablets in the fed state
Each subject is planned to be randomly allocated to one of the two treatment sequences (T-R 
or R-T) in a 1:1 ratio.
In addition to the two investigational treatments stated above, the following non-
investigational provoking agent will be used:

provoking agent (NIMP)
50 μg CCK-4 (cholecystokinin tetrapeptide) as i.v. bolus injection
For the selection of subjects included in the trial, subjects able and willing to participate will 
be exposed to the provoking agent CCK-4 at screening. After identification of CCK-4 
sensitive subjects (cf. Section 3.3 of the CTP), trial subjects will be exposed to CCK-4 again 
within each treatment period. 
For statistical analyses of AEs, the following separate analysis phases will be defined for 
each subject:

CTR Section 15, Appendix 16.1.13.1.8.2 and Appendix 16.1.13.1.8.3 AE displays will 
present results for the on-treatment phase only.
In CTR Section 15, AE tables (but not in Appendix 16.1.13.1.8.2 and Appendix 16.1.13.1.8.3 
AE tables), the following totals will be provided in addition: 

"Total on treatment", defined as the total over all on-treatment phases
CTR Appendix 16.1.13.1.8.1 displays will present results for the screening and on-treatment
phases.
Additionally to the total defined above, the following total will be provided in CTR 
Section 16.1.13.1.8.1 AE tables:

"Total", defined as the total over all study phases (screening + on-treatment)
Statistical analyses of safety laboratory tests and vital signs will be conducted by treatment 
period (BI 1358894 or Placebo), with clear differentiation between baseline (cf. Section 6.7) 
and on-treatment measurements.
More details on the technical implementation of these analyses are provided in the ADS Plan 
of this TSAP.
6.2
IMPORTANT PROTOCOL DEVIATIONS
Consistency check listings (for identification of deviations from time windows) and a list of 
protocol deviations (e.g. deviations in drug administration, in blood sampling times, etc.) will 
be provided to be discussed at the Report Planning Meeting. At this meeting, it will be 


Boehringer Ingelheim
TSAP for BI Trial No: 1402-0005

Proprietary confidential information © 2019 Boehringer Ingelheim International GmbH or one or more of its affiliated companies
decided whether a discrepant data value can be used in analyses or whether it must be 
corrected in the clinical database. Each protocol deviation must be assessed to determine 
whether it is an iPD. For definition of iPDs, and for the process of identification of these, 
refer to the BI reference document "Identify and Manage Important Protocol Deviations 
(iPD)" (2).
If any iPDs are identified, they are to be summarised into categories and will be captured in 
the minutes of the Report Planning Meeting via an accompanying Excel spreadsheet (3).
Categories which are considered to be iPDs in this trial are defined in the integrated quality 
and risk management plan (IQRMP). If the data show other iPDs, the definition in the 
IQRMP will be supplemented accordingly by the time of the Report Planning Meeting.
iPDs will be summarized and listed. Table 6.2: 1 below specifies which kind of iPDs could 
potentially lead to exclusion from which analysis set. The decision on exclusion of patients 
from analysis sets will be made at the latest at the Report Planning Meeting, after discussion 
of exceptional cases and implications for analyses.

SUBJECT SETS ANALYSED
As stated in Section 4 of this TSAP, the ES and ENTS will not be used, as the data of these 
subjects are not in the CDR. The PDS and PKS will be used as defined in the CTP, Section 
7.3. In this Section, the treated set was defined as:
Treated set (TS):
This subject set includes all subjects from the ENTS who were documented to have received 
at least one dose of study drug.


Boehringer Ingelheim
TSAP for BI Trial No: 1402-0005

Proprietary confidential information © 2019 Boehringer Ingelheim International GmbH or one or more of its affiliated companies
For clarification, the definition of the TS will be specified further as:
Treated set (TS):
This subject set includes all subjects that underwent screening procedures, entered the trial 
and were documented to have received at least one dose of investigational study drug.
The following Table 6.3: 1 contains the information which subject is used for which class of 
endpoint:

POOLING OF CENTRES
This section is not applicable, because the study is performed in only one centre.
6.6
HANDLING OF MISSING DATA AND OUTLIERS
Data of screened subjects who were withdrawn from the trial prior to first administration of 
investigational study drug will not be reported in the CTR.
Data of subjects who drop out or withdraw from the trial will be reported in the CTR as far as 
their data are available. All withdrawals will be documented and the reason for withdrawal 
reported in the CTR.
Handling of missing PD data will be done as described in CTP Section 7.5.3:
For the PD endpoints PSS 
, if the period baseline value is missing in treatment
period 1, it will be imputed by the corresponding value measured in treatment period 2. If the
period baseline value is missing in treatment period 2, it will be imputed by the


Boehringer Ingelheim
TSAP for BI Trial No: 1402-0005
Page 18 of 32
Proprietary confidential information © 2019 Boehringer Ingelheim International GmbH or one or more of its affiliated companies
corresponding value measured in treatment period 1. If a value is missing after CCK-4
injection, this value will not be imputed. If all four assessments after CCK-4 injection are
missing for a subject, this subject is not evaluable for this endpoint in this period.
CTP Section 7.5.1: It is not planned to impute missing values for safety parameters.
One exception where imputation might be necessary for safety evaluation are AE dates. 
Missing or incomplete AE dates are imputed according to BI standards.
CTP Section 7.5.2: PK parameters that cannot be reasonably calculated based on the 
available drug concentration-time data will not be imputed.
Missing data and outliers of PK data are handled according to BI standards (4).
6.7
BASELINE, TIME WINDOWS AND CALCULATED VISITS
A separate baseline is defined for each study treatment. The baseline is the last available 
value before administration of the CCK-4 challenge in the respective treatment period. E.g. 
for PSS sum intensity score 
 baseline is the value measured 15 minutes before 
administration of the CCK-4 challenge within the respective treatment period.
In addition, for vital signs displays where PTM -2:00 are considered as baseline will be 
provided.
Time windows are defined in Section 6.1 of the CTP. Adherence to time windows will be 
checked at the Report Planning Meeting.
Unscheduled measurements of laboratory data or vital signs data will be assumed to be repeat 
measurements of the most recent scheduled measurement (e.g. for follow-up or confirmation 
of a particular value). Therefore, unscheduled measurements will be assigned to the planned 
time point of the previous scheduled measurement.
Descriptive statistics of laboratory data will be calculated by planned time point based on the 
worst value of the subject at that planned time point (or assigned to that planned time point).
For vital signs, descriptive statistics will be calculated by planned time point based on the last 
value of the subject at that planned time point (or assigned to that planned time point).

PLANNED ANALYSIS
The format of the listings and tables will follow the standards defined in the BI standards
with the exception of those generated for PK-calculations (6).
The individual values of all subjects will be listed. Listings will be sorted by treatment 
sequence, subject number and visit (if visit is applicable in the respective listing). AE listings 
will be sorted by assigned treatment (see Section 7.8.1 below for details). The listings will be 
contained in Appendix 16.2 (SDL) of the CTR.
The following standard descriptive statistical parameters will be displayed in summary tables 
of continuous variables:
N 
number of non-missing observations
Mean 
arithmetic mean
SD 
standard deviation
Min 
minimum
Median 
median
Max 
maximum
For plasma concentrations as well as for all PK parameters the following descriptive statistics 
will additionally be calculated:
CV 
arithmetic coefficient of variation
gMean
geometric mean
gCV
geometric coefficient of variation
For PK parameters the following descriptive statistics will additionally be calculated:
P10
10th percentile
Q1
1st quartile
Q3
3rd quartile
P90
90th percentile
The data format for descriptive statistics of plasma concentrations will be identical with the 
data format of the respective concentrations. The descriptive statistics of PK parameters will 
be calculated using the individual values with the number of decimal places as provided by 
the evaluation program. Then the individual values as well as the descriptive statistics will be 
reported with three significant digits in the CTR.
Tabulations of frequencies for categorical data will include all possible categories and will 
display the number of observations in a category as well as the percentage (%) relative to the 
respective treatment group. Percentages will be rounded to one decimal place. The category 
missing will be displayed if and only if there actually are missing values. Percentages will be 
based on all subjects in the respective subject set whether they have non-missing values or 
not.

complete intake will be addressed in the Report Planning Meeting (cf. Section 6.2) and 
described in the CTR.
7.4
PRIMARY ENDPOINT
CTP Section 7.3.1: “The derivation of the primary endpoint PSS sum intensity score per time 
point is outlined in Section 5.6.3. The maximum CfB is defined as the maximum of the 
differences of the PSS sum intensity score measured at each time point after the CCK-4 
challenge minus the PSS sum intensity score measured at baseline.”
7.4.1
Primary analysis of the primary endpoint
The primary endpoint will be analyzed based on the PDS.
Descriptive statistics and boxplots of the primary endpoint by treatment will be provided.
As main analysis, the following model will be applied:

The last value before administration of the CCK-4 challenge in each period is considered as 
the corresponding period baseline measurement. The PSS sum intensity score mean value of 
the two period baseline values is considered as the subject baseline.
The treatment comparison will be the difference between active treatment and placebo. 
Adjusted means (Least Squares Means) as well as 2-sided 90% CIs will be calculated. 
Additionally, the difference in adjusted means relative to placebo will be provided. To 
support this analysis, listings and graphical displays may be generated if appropriate. 
As a sensitivity analysis, the same statistical model as stated above will be repeated for the 
primary endpoint but with all sources of variation considered as fixed effects.”
For the random ‘subject’ effect in the above model a Variance Components (VC) covariance 
structure will be used; in case of convergence problems refer to Additional Section 9.2. The 
SAS procedure MIXED will be used involving the restricted maximum likelihood estimation 
and the Kenward-Roger approximation for denominator degrees of freedom. This approach is 
described in Kenward and Roger (8).
Programming details are provided in Section 9.1.1.

7.7
EXTENT OF EXPOSURE
Treatment exposure will be listed by means of the date and time of drug administration.
7.8
SAFETY ANALYSIS
All safety analyses will be performed on the TS.
7.8.1
Adverse Events
AEs will be coded with the most recent version of MedDRA.
The analyses of AEs will be descriptive in nature. All analyses of AEs will be based on the 
number of subjects with AEs and not on the number of AEs.
For analysis, multiple AE occurrence data on the eCRF will be collapsed into one event 
provided that all of the following applies:

All AE attributes are identical (lower level term, intensity, action taken, therapy required, 
seriousness, reason for seriousness, relationship, outcome, AESI)

The occurrences were time-overlapping or time-adjacent (time-adjacency of two 
occurrences is given if the second occurrence started at most 1 hour after the first 
occurrence ended)
The analysis of AEs will be based on the concept of treatment emergent AEs. That means 
that all AEs will be assigned to screening or on-treatment phases as defined in Section 6.1. 
AEs will be analysed based on actual treatments, as defined in Table 6.1: 1.
An overall summary of AEs will be presented. This overall summary will comprise summary 
statistics for the class of other significant AEs according to ICH E3 (7) and for the class of 
AESIs.
CTP, Section 5.2.6.1.6: “The following are considered as AESIs:

Hepatic injury
A hepatic injury is defined by the following alterations of hepatic laboratory 
parameters:
○
An elevation of AST (aspartate transaminase) and/or ALT (alanine 
transaminase) ≥3-fold ULN combined with an elevation of total bilirubin ≥2-fold ULN 
measured in the same blood sample, or 
○
Aminotransferase (ALT, and/or AST) elevations ≥10 fold ULN”

The investigator had to classify on the eCRF whether an observed AE was an AESI or not.
According to ICH E3 (7), AEs classified as "other significant" need to be reported and will 
include those non-serious and non-significant AEs
(i) which are marked haematological or other lab abnormalities, or
(ii) which were reported with "action taken = discontinuation" or "action taken = reduced", or
(iii) which lead to significant concomitant therapy as identified by the Clinical 
Monitor/Investigator at a Medical Quality Review Meeting. 
The frequency of subjects with AEs will be summarised by treatment, primary SOC and 
preferred term. AEs which were considered by the investigator to be drug related will be 
summarised separately. Separate tables will also be provided for subjects with SAEs, subjects 
with AESIs and subjects with other significant AEs (according to ICH E3 (7)). The frequency 
of subjects with AEs and the frequency of subjects with AEs considered by the investigator to 
be drug related will also be summarised by maximum intensity, primary SOC and preferred 
term.
The SOCs and preferred terms within SOCs will be sorted by descending frequency over all 
treatment groups.
For disclosure of AE data on ClinicalTrials.gov, the frequency of subjects with non-serious 
AEs occurring with an incidence of greater than 5 % (in preferred terms) will be summarised 
by treatment, primary SOC and preferred term. The frequency of subjects with SAEs will 
also be summarised.
For disclosure of AE data in the EudraCT register, the frequency of AEs, the frequency of 
non-serious AEs with an incidence of greater than 5 % (in preferred terms) and the frequency 
of SAEs will be summarized.
For support of lay summaries, the frequency of subjects with drug-related SAEs will be 
summarized by treatment, primary SOC and preferred term.
If the subject reports headaches during the treatment period further information about the 
duration of headache, headache severity (NRS), location, characteristics, and signs and 
symptoms were recorded. The information will be summarized with descriptive statistics.
7.8.2
Laboratory data
The analyses of laboratory data will be descriptive in nature and will be based on BI 
standards.
Analyses will be based on normalised values, which means transforming to a standard unit 
and a standard reference range. The original values will be analysed if the transformation into 
standard unit is not possible for a parameter.

Descriptive statistics of laboratory values over time and for the difference from baseline (see 
Section 6.7) will be provided. Frequency tables of changes between baseline and last value on 
treatment with respect to the reference range will be presented.
Possibly clinically significant abnormal laboratory values are only those identified either in 
the Investigator's comments or at the Report Planning Meeting at the latest. It is the 
Investigator's responsibility to decide whether a lab value is clinically significant abnormal or 
not. Standard or project-specific rules for flagging clinically significant values in an 
automated manner will not be applied in this study.
Clinically relevant findings in laboratory data will be reported as baseline conditions (prior to 
first administration of study treatment) or as AEs (after first administration of study treatment) 
if judged clinically relevant by the investigator, and will be analyzed as such.
7.8.3
Vital signs
The analyses of vital signs (blood pressure and pulse rate) will be descriptive in nature. 
Descriptive statistics of vital signs over time and for the difference from baseline (see 
Section 6.7) will be provided.
Clinically relevant findings in vital signs data will be reported as baseline conditions (prior to 
first administration of study treatment) or as AEs (after first administration of study treatment)
if judged clinically relevant by the investigator, and will be analyzed as such.
7.8.4
ECG
Relevant ECG findings will be reported as relevant medical history/baseline condition (if a 
condition already exists before first administration of study treatment) or as AE (if condition 
emerges after first administration of study treatment) and will be summarized as such. No 
separate listing or analysis of ECG findings will be prepared.
7.8.5
Others
7.8.5.1 
Physical examination
Physical examination findings will be reported as relevant medical history/baseline condition 
(if a condition already exists before first administration of study treatment) or as AE (if 
condition emerges after first administration of study treatment) and will be summarized as 
such. No separate listing or analysis of physical examination findings will be prepared.

Neurological examination
Clinically relevant findings of the neurological examination will be reported as relevant 
medical history/baseline condition (if a condition already exists before first administration of 
study treatment) or as AE (if condition emerges after first administration of study treatment) 
and will be summarized as such. No separate listing or analysis of neurological examinations
will be prepared.
