Title of trial:
Safety, tolerability and pharmacokinetics of single rising oral doses of BI 1358894 in 
healthy male subjects (single-blind, partially randomised, placebo-controlled parallel 
group design)  and effect of food on the relative bioavailability of BI 1358894 (open-
label, randomised, two-way cross-over)
Principal Investigator:
Trial site:
Clinical phase:
I
Objectives:
To investigate safety, tolerability, and pharmacokinetics (PK) following single rising 
doses including food effect of BI 1358894
Methodology:
-
Single rising dose (SRD): single-blind, partially randomised within dose groups, 
placebo-controlled, parallel-group design
-
Food effect (FE): randomised, open label, two-way, two-sequence
cross-over design
No. of subjects: 
total entered:
*88
each treatment:
SRD: 8 per dose group (6 on active drug and 2 on placebo)
FE: 24 (all on active treatment)
* The study will be initially conducted with a tablet formulation and 8 dose groups resulting in 
a planned number of 64 subjects in the SRD part and 24 subjects in the FE part. 
Additional subjects may be entered to allow testing of additional doses on the basis of 
experience gained during the trial conduct (e.g. preliminary PK data), provided the planned
and approved highest dose will not be exceeded. Thus, the actual number of subjects entered 
may exceed 88, but will not exceed 96 subjects entered.
The food effect part will not start before the respective dose has been tested in the SRD part, 
Diagnosis:
Not applicable
Main criteria
for inclusion:
Healthy male subjects, age of 18 to 45 years, body mass index (BMI) of 18.5 to 
29.9 kg/m2

Test product 1:
BI 1358894 film-coated tablet (tablet strength 1 mg, 5mg, 25 mg 100 mg)
dose:
SRD*: 3 mg, 6 mg, 10 mg, 25 mg, 50 mg, 100 mg, 200 mg (fasted q.d.), FE:, 50 mg,
and 100 mg
SRD fed: 200 mg (fed)* q.d. 
* Dose selection based on the assumption to include the potential therapeutic range. In the SRD 
part doses may be decreased or increased based on the knowledge gained during trial conduct 
(e.g. safety, exploratory PK analyses). In any case, the selected dose must not exceed the 
approved dose range. The food effect part will not start before the respective dose has been 
studied in the SRD part.
**The estimated exposure of 200 mg of BI 1358894 administered under fed conditions may 
exceed the current exposure threshold Cmax of 980 nM or an AUC0-24h of 9500 nM*h. Since at 
the time of this 200 mg fed dose group clinical data up to 200 mg fasted and 100 mg fed are
available, the exposure threshold for the dose group of 200 mg administered under fed 
conditions will be further increased to the exposure at NOAEL in rats (i.e. Cmax of 1960 nM and 
an AUC0-24 of 26300 nM*h). The exposure in previous fed dose groups indicates that the 
geometric mean of the AUC0-24 for the 200mg fed group is predicted to be 15400 nM*h and the 
geometric mean of Cmax is predicted to be 1127 nM, i.e. below the new  threshold. Even based 
on the 95% prediction interval the threshold would not be exceeded.

Criteria for safety:
Primary endpoint to assess safety and tolerability of BI 1358894 is the number 
[N (%)] of subjects with drug related adverse events.
Further criteria of interest:
AEs including clinically relevant findings from the physical examination, safety 
laboratory tests, 12-lead electrocardiogram (ECG), continuous ECG monitoring, vital 
signs (blood pressure [BP], pulse rate [PR], respiratory rate [RR]), orthostatic test and 
Bond & Lader and Bowdle visual analogue scales and suicidality assessment 
(C-SSRS).
Statistical methods:
Descriptive statistics will be calculated for all endpoints.
The PK parameters AUC and Cmax will be explored for dose proportionality of BI 
1358894 using a regression model; a 95% confidence interval (CI) for the slope will
be computed.
The statistical model to assess relative bioavailability in the food effect part will be an 
analysis of variance (ANOVA) on the ln-transformed parameters AUC and Cmax
including effects for "sequence", "subjects nested within sequences", "period" and 
"treatment". Point estimators (geometric means) for the ratios of response under test 
compared to reference treatment and their two-sided 90% confidence intervals will be 
calculated.
Confidence intervals will be based on the residual error from ANOVA

INTRODUCTION
1.1
MEDICAL BACKGROUND
Boehringer Ingelheim (BI) is developing BI 1358894, an oral, small-molecule inhibitor of a 
transient receptor potential cation channel, subfamily C,  members 4 and 5 (TRPC 4/5) for 
major depressive disorder (MDD) as an adjunct to antidepressant therapy and for the
treatment of borderline personality disorder (BPD), that has not yet been tested in humans.
MDD is a debilitating disease that is difficult to treat, even when using systematic 
antidepressant strategies. In the National Institute of Mental Health (NIMH) funded STAR*D 
trial of > 4000 patients with nonpsychotic depression, about 30% of the patients did not reach 
remission after 4 different medications [P06-11895] and continued to experience residuals 
symptoms [R16-5475] which significantly impacted the patients’ quality of life [R06-2872]. 
When monotherapy is insufficient, clinicians employ different augmentation strategies 
including add-on treatment with lithium or atypical antipsychotics. When augmentation 
strategies also fail, convulsive therapies such as electro-convulsive therapy (ECT) may be 
used.
Borderline personality disorder (BPD) is a chronic mental disorder with an estimated
prevalence of around 2% in the general community [R16-5476] and severe impairment of
quality of life [R16-5474]. The main symptom clusters of BPD include impulsive-
behavioural dyscontrol, cognitive-perceptual symptoms, disturbed interpersonal relations and 
affective instability. Patients with BPD have high rates of deliberate self-harm and a rate of 
completed suicide that is 50 times higher than in the general population [R16-5477]. Even the 
presence of a single diagnostic feature of BPD is predictive for poor functioning and 
psychiatric illness burden [R16-5483]. Treatment guidelines recommend psychotherapy as 
the mainstay of treatment, but pharmacotherapy is commonly used as an adjunctive, 
symptom-targeted component of treatment. However, no drug is approved for the treatment 
of BPD.
TRPC4 and TRPC5 form ion channels that are involved in the regulation of neuronal
excitability. They are most highly expressed in the amygdala, in the frontal cortex,
hippocampus, and hypothalamus [R15-3888; R16-5350] which are involved in modulation
and processing of emotion and affect. Pre-clinically, treatment with BI 1358894 has shown
diminished fear and anxiety and increased social interaction without impairing other brain
functions such as learning and memory behaviours.
It is hypothesized that in patients with affective disorders, an overactive amygdala is a major
contributor to attentional bias to negative stimuli, pessimistic thoughts and anxiety [R16-
5473] and there is growing evidence supporting the role of amygdala in the emotion  
processing disturbances observed in patients with BPD [R16-5472]. Therefore, it is expected
that treatment with BI 1358894 has the potential to improve affective symptoms and emotion
control in patients with MDD and BPD.
The clinical development program will first explore the clinical pharmacology of BI 1358894
in healthy volunteers and subsequently in patients with MDD and BPD.

RATIONALE, OBJECTIVES, AND BENEFIT - RISK 
ASSESSMENT
2.1
RATIONALE FOR PERFORMING THE TRIAL
TRPC4 and TRPC5 form ion channels that are involved in the regulation of neuronal
excitability. They are highly expressed in the amygdala and other CNS regions [R15-3888; 
R16-5350] which are involved in modulation and processing of emotion and affect. It is 
hypothesized that in patients with affective disorders, an overactive amygdala is a major
contributor to attentional bias to negative stimuli, pessimistic thoughts and anxiety [R16-
5473] . Inhibition of TRPC4/5 ion channels by BI 1358894 may therefore have the potential 
to improve affective symptoms and emotion control in patients with affective disorders.
As a transition from preclinical investigations to clinical development in this first-in-man 
trial, safety, tolerability, and pharmacokinetics of BI 1358894 will be assessed in healthy 
male volunteers using single rising oral doses. The study will provide the basis for potential 
further clinical development of BI 1358894 in patients with MDD and BPD.
Healthy male subjects aged 18 - 45 years will be recruited for this study. They provide a 
relatively stable physiological and biochemical basis for studying drug effects, they show no 
disease-related variation and they are not taking concomitant medication. 
In the single rising dose (SRD) part, within each dose group, all actively treated individuals 
will receive the same BI 1358894 dose. The next higher dose will only be administered (to 
the next group) if the treatment in the preceding dose groups was safe and showed acceptable 
tolerability.
In the relative bioavailability (BA) part, up to 3 dose groups may be studied in a two-way-
crossover fashion. This will help gain information about the effect of food on the exposure of 
BI 1358894 and will support upcoming clinical studies with respect to better trial designs, 
and to help if needed in the optimization for future trial-formulation development.
Dose selection
It is intended to investigate the following dose levels of BI 1358894 in the SRD part of this 
trial: 3 mg, 6 mg, 10 mg, 25 mg, 50 mg, 100 mg, and 200 mg. The background for this dose 
selection is described in the following paragraphs.

In order to cover the anticipated dose range, a stepwise and careful dose increase has been 
selected for this trial. The escalation schedule has been chosen in a way that a shallow 
escalation will be applied for the higher dose levels with a factor not greater than 2.5. This 
dose escalation is considered to be adequate and safe.
2.2
TRIAL OBJECTIVES
The primary objective of this trial is to investigate the safety and tolerability of BI 1358894 in 
healthy male subjects following oral administration of single rising doses of 3 mg, 6 mg, 
10 mg, 25 mg, 50 mg, 100 mg, and 200 mg.
Secondary objectives are the exploration of the pharmacokinetics (PK), including dose 
proportionality of BI 1358894 after single dosing.
The objective of the FE part will be to explore the influence of food on the relative 
bioavailability of BI 1358894.
A description of the endpoints to be determined and the observations to be performed, along
with specific information as how to collect the data for that information, is provided in 
Section 5.
2.3
BENEFIT - RISK ASSESSMENT
Participation in this study is without any (therapeutic) benefit for healthy subjects. Their 
participation in the study, however, is of major importance to the development of BI 
1358894. The subjects are exposed to the risks of the study procedures and the risks related to 
the exposure to the trial medication.
2.3.1
Procedure-related risks
The use of an indwelling venous catheter for the purpose of blood sampling may be 
accompanied by mild bruising and also, in rare cases, by transient inflammation of the wall of 
the vein. In addition, in rare cases a nerve might be injured while inserting the venous 
catheter, potentially resulting in paresthesia, reduced sensibility, and/or pain for an indefinite 
period. The same risks apply to venipuncture for blood sampling.

The total volume of blood withdrawn during the entire study per subject will not exceed the 
volume of a normal blood donation (500 mL). No health-related risk to healthy subjects is 
expected from this blood withdrawal.
2.3.2
Risks related to the intake of BI 1358894
2.3.2.1
Risks derived from observations in non-clinical studies
Rats and dogs were employed as the animal species for general toxicology investigations on 
BI 1358894, because in-vitro and in-vivo profiling supported the suitability of both species 
for nonclinical safety profiling of BI 1358894.
As summarized in Section 1.2.3, potential risks observed in non-clinical studies are a long 
lasting decrease of blood pressure in rats, an increase in heart rate in rats and dogs, and signs 
of a short lasting episode of arterial/ perivascular inflammation in rats. All findings were 
observed within 5 days after start of treatment. The CV effects observed in rodents and non-
rodents can be easily monitored in a Phase I study (CV effects). Perivascular/mesenteric
inflammation induced by BI 1358894 occurred early after start of dosing and resolved despite 
continued treatment, indicating its transient character. The non-clinical safety data support 
clinical Phase I trials in non-childbearing humans with daily oral administration for up to 4 
weeks.
2.3.2.2
Drug-related risks and safety measures
Mode of action and nature of the target
The TRP family are ion channels considered to play a crucial role in physiological processes 
such as to act as a cellular sensor or to support signal transmission (Minke 2010). The 
subtypes TRPC4 and TRPC5 form ion channels that are involved in the regulation of 
neuronal excitability. They are highly expressed in the amygdala, in the frontal cortex,
hippocampus, and hypothalamus [R15-3888; R16-5350], which are involved in modulation 
and processing of emotion and affect. Pre-clinically, inhibition of these receptors by BI 
1358894 has shown diminished fear and anxiety and increased social interaction without 
impairing other brain functions such as learning and memory behaviours. In accordance with 
these findings, TRPC5 deficient mice display an anxiolytic-like phenotype (Riccio, 2009).  
This is considered to support the assumption that CNS effects in healthy subjects due to an 
inhibition of TRPC 4/5 are limited to a reduced anxiety. However, clinical data with 
compounds inhibiting this target have yet to be published.
Relevance of animal models
Human TRPC4 and TRPC5 proteins show high homology with the rat, mouse and dog 
proteins, and potency of BI 1358894 to the target is comparable across species. In addition, 
expression at the protein level is similar across different species including human. Rat and 
dog had good oral bioavailability, significant systemic exposure and good tolerability after 
oral dosing of a nanosuspension of BI 1358894. Finally, all known metabolites formed after 
incubation of human hepatocytes with BI 1358894 were covered with the combination of rat 
and dog. Overall, pharmacodynamic activity, pharmacokinetics and metabolism all indicated 
that rat and dog were suitable species for nonclinical safety profiling of BI1358894.

It should be highlighted that toxicity study in rats [n00250347] did not reveal any 
toxicologically relevant effects of BI 1358894 on the immune system up to the highest tested 
dose of 2000 mg/kg (1000 m/kg twice daily). Furthermore, the pharmacological effects of BI 
1358894 are dose dependent and no evidence for irreversible effects has been observed.
Therefore, despite the novelty of the target, BI 1358894 is not considered a high-risk 
compound. 
2.3.2.3
Risk minimization (safety precautions and stopping rules)
The following safety measures will be applied in this study in order to minimize the risk for 
healthy volunteers:

Careful dose selection as described in Section 2.1.

Preliminary measurement of BI 1358894 plasma concentrations and preliminary 
determination of PK parameters (Cmax, AUC0-24; see Section 7.3.4). For precautionary 
reasons, drug plasma concentrations of healthy volunteers in this trial should not 
exceed the mean Cmax of 980 nM or mean AUC0-24 of 9500 nM*h, which will be 
considered a preliminary threshold (see Section 2.1). Further dose progression would 
only be allowed after a safety interim analysis and filing and approval of a substantial 
CTP amendment. For subjects receiving 200 mg of BI 1358894 under fed conditions  
that the geometric mean of the AUC0-24 is predicted to be 15400 nM*h and the 
geometric mean of Cmax is predicted to be 1127 nM. Based on the 95% prediction 
interval the threshold (NOAEL in rats: Cmax of 1960 nM or mean AUC0-24 of 26300 
nM*h) would not be exceeded.

An extensive safety laboratory will be performed with special focus on full blood 
exam (see Flow Chart).

For safety reasons, during the single rising dose part each dose group of 8 subjects 
(6 on active, 2 on placebo) will be divided into three cohorts: on the first study day of 
each dose level, only 2 subjects will be treated: one will receive active treatment, the 
other subject will receive placebo. If BI 1358894 treatment is safe and tolerated in this 
first cohort, 2 subjects on active will be treated in the second cohort no sooner than on 
the next day and could be dosed as close as 2 h apart. The remaining 4 subjects (either 
active or placebo) are the third cohort and will be treated no sooner than after 2 days 
following the first cohort. This design ensures that between first and second active 
dose of each dose level there is a time interval of at least 1 day, which covers the 
Tmax of BI 1358894 and the period of highest risk / peak effect. If BI 1358894 was 
safe and showed acceptable tolerability in the first two cohorts, the remaining third 
cohort of the respective dose level could be dosed as close as 10 minutes apart.
During the single rising dose part, a thorough ECG monitoring including continuous 
ECG measurement over 4 hours post dose to cover the anticipated period of highest 
drug exposure and additional repeated single 12-lead ECGs over 96 hours (for Dose 
Group 200 mg fed up to 144 h) following drug administration. Dose escalation would 
be stopped as soon as at least 2 subjects at one dose level showed relevant QT 
prolongation (see Section 3.3.4.2 for details).


In this study, blood pressure and heart rate will be closely monitored (see Flow 
Chart). Orthostatic testing will be performed to detect whether potential 
hemodynamic effects of BI 1358894 might interfere with daily life activities. Dose 
escalation will be stopped if orthostatic dysregulation (see Section 5.2.5.2 for 
definition) is observed in more than 1 subject (severe) or more than 3 subjects 
(moderate) per dose group.

Adequate safety monitoring will be performed (e.g. vital signs including ECGs, safety 
laboratory tests including hormone parameters, adverse events including Bond & 
Lader visual analogue scales and suicidality assessment by C-SSR).

The subjects will stay at the trial site for at least 48 hours after study drug 
administration at each dose level. Based on the initially anticipated terminal half-life 
for BI 1358894 of approximately 15 hours, this is expected to cover the period of 
highest risk / peak effect.

The subjects assigned to Dose Group 200 mg fed will stay at the trial site for at least 
144 hours after study drug administration. For a period of at least 24 hours after intake 
of study drugs which is expected to cover the period of highest risk / peak effect, a 
physician will stay at the study site to allow, if needed, immediate emergency 
intervention and rescue measures.

During in house-confinement, the subjects will be under medical observation and 
thoroughly monitored for both expected and unexpected adverse events.

Only if the respective dose of BI 1358894 is safe, shows acceptable tolerability, and 
no stopping criterion are met (refer to Section 3.3.4.2), the next higher dose will be 
given (at least 6 days later, referring to the 1st subject of each dose group).

The food effect part with 50 mg will only start after the completed SRD part.  Further 
dose levels may be tested based on safety and tolerability of the completed SRD part, 
as long as predicted exposure will remain below the predefined thresholds (mean Cmax
of 980 nM or mean AUC0-24 of 9500 nM*h).As reproductive toxicity studies have not 
yet been conducted, women of child-bearing potential will not be enrolled in this 
study.
2.3.2.4
Drug induced liver injury
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 5.2.2.1).
2.3.3
Overall assessment
In summary, although not tested in humans to date, BI 1358894 has the potential to become 
an oral treatment for major depressive disorder as an adjunct to antidepressant therapy and for 
the treatment of borderline personality disorder. Based upon preclinical data for BI 1358894,
as well as the implemented safety measures described above, healthy subjects will not be 
exposed to undue risks 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 this FIM clinical trial with BI 1358894, as is 
the usual case in such Phase I trials. Considering the medical need of the development of a 
safer and more effective treatment for patients with Mood and Borderline Personality 
disorders, 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
This FIH study consists of an SRD and an FE part. The SRD part is designed as single-blind, 
partially randomised, and placebo-controlled within parallel dose groups, while the FE part 
will be conducted according to an open-label, randomised, two-way crossover design.
SRD:
The SRD part will start with a tablet formulation. In case the tablet formulation will be used 
up to the final dose group, 64 healthy male subjects will be included, according to 8 
sequential groups comprising 8 subjects per group. However, based on in vitro data, there is a 
possibility that due to the low solubility of the drug substance and tablet, the exposure in 
subjects will be limited and increase may be less than dose proportional (see Section 7.3.4). 
Further subjects may be entered to allow testing of additional doses on the basis of 
experience gained during the trial conduct (e.g. preliminary PK data), provided the planned 
and approved highest dose will not be exceeded. Thus, the actual number may exceed 64, but 
will not exceed 72 subjects entered. Such changes may be implemented via non-substantial 
CTP Amendments.
Within each dose group, 6 subjects will receive the active drug and 2 will receive placebo. 
Only one dose is tested within each dose group. Each dose group will consist of 3 cohorts 
which will be treated consecutively for safety reasons.
The dose groups to be evaluated are outlined in Table 3.1: 1 below.

*Administration under fed conditions
The dose groups of the SRD part will be investigated sequentially in ascending order of 
doses, maintaining a time interval of at least 5 days between the last drug administration in 
the previous dose group and the first drug administration of the subsequent dose group. The 
decision to proceed to the next dose group will be based upon the safety, tolerability, and 
exploratory pharmacokinetic data (see Section 7.3.4) of the preceding dose groups. The next

dose will only be given if, in the opinion of the investigator, no safety concerns arose in the 
preceding dose group (i.e. no dose-limiting events occurred) and if none of the pre-specified 
trial-specific stopping criteria were met (refer to Section 3.3.4.2).
FE part
The food effect part will be performed as a randomised, open label, single-dose, two -
sequence, two-way cross-over 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 4 treatments will be two 25 mg tablets and one 
100 mg tablet in the fasting state (R) and two 25 mg tablets and one 100 mg tablet after a 
standardised high fat breakfast (T). The dose strengths to be tested (lowest and maximum 
dose) will be re-evaluated after explorative safety and PK analysis.  For details, refer to 
Section 4.1. There will be a washout period of at least 7 days between the treatments. A total 
of 24 healthy male subjects are planned to participate in the FE part. An overview of all 
relevant trial activities is provided in the Flow Chart.
For visit schedule and details of trial procedures at selected visits, refer to Sections 6.1 and 
6.2, respectively.
The possible dose groups to be evaluated are outlined in Table 3.1: 2 below.

A documented Safety Review must take place prior to each dose escalation. Furthermore, an 
unscheduled safety review meeting can be requested anytime for any reasonable cause by the 
Principal Investigator (or an authorised deputy) or the sponsor of the study, e.g. because of 
any unforeseen adverse events, etc. Dose escalation will only be permitted if no safety 
concerns exist in the opinion of the Principal Investigator (or an authorised deputy) and the 
trial clinical monitor (or an authorised deputy).
The minimum data set for review consists of the following data:

AEs in the current and preceding dose groups (including clinically relevant findings 
from ancillary safety testing listed below) (Note: AEs may be ongoing at the time of 
Safety Reviews and AE information may be subject to change prior to Database Lock)

Vital signs and results from the orthostatic test in the current and preceding dose
groups

Clinical laboratory tests in the current and preceding dose groups

Preliminary PK data for selected groups as defined in Section 7.3.4. 

Check of criteria for stopping subject treatment as per Section 3.3.4.1
The decision to escalate the dose will be made jointly by the Principal Investigator (or an 
authorised deputy) and the trial clinical monitor (or an authorised deputy) after in-depth 
analysis of all available safety data, especially SAEs (if occurred), AEs and out-of-range 
laboratory results (if considered clinically significant). Safety Reviews can be conducted 
face-to-face or by video/telephone conference. The Principal Investigator is responsible for 
organization and minutes of the reviews. Minutes will be signed off by the Principal 
Investigator (or an authorised deputy) and filed in the ISF and TMF.
The investigator (after consultation with the sponsor) is allowed to alter the scheduled dose 
levels (e.g. add low and/or intermediate dose levels) on the basis of experience gained during 
the study, provided the planned and approved highest dose is not exceeded. In this case, the 
total number of subjects in this trial might increase. The investigator and/or the sponsor 
should stop dose escalation in case the safety evaluation leads to concerns that would not 
allow higher dosing.

according to BI SOPs. A list of responsible persons and relevant local information can be 
found in the ISF.
3.2
DISCUSSION OF TRIAL DESIGN, INCLUDING THE CHOICE OF 
CONTROL GROUPS
For single-rising dose trials, the design described in Section 3.1 is considered favourably
under the provision not to expose the subjects involved to undue risks since the main study 
objective is to investigate safety and tolerability of BI 1358894.
With the rising dose design, single-blind conditions regarding the subject’s treatment (active 
or placebo) are maintained within each dose group. However, the current dose level will be 
known to subjects and investigators. The disadvantage of this trial design is a possible 
observer bias with regard to potential dose-dependent effects, as well as time effects, but it 
has the virtue of minimizing subject risk by sequentially studying ascending doses. As time-
effects are expected to be small relative to the differences between the doses in the broad 
range investigated, unbiased comparisons between treatments can still be expected.
It is standard in trials involving healthy volunteers to include a placebo group as control for 
the evaluation of safety, tolerability and pharmacodynamic effects. Each dose group consists 
of 8 subjects with 6 on active treatment, and 2 on placebo. The placebo control group 
includes all subjects of all dose groups treated with placebo. Six subjects per active treatment 
group are in general considered as sufficient for the exploratory evaluation of 
pharmacokinetics. 
3.3
SELECTION OF TRIAL POPULATION
It is planned that up to 64 healthy male subjects will enter the SRD part (8 per dose group, 6 
on active and 2 on placebo) and 24 healthy males will enter the FE part (12 per dose group, 
all on active) of the study. The actual number of subjects entered may exceed the total of 88 
if additional intermediate doses will be tested (see Section 3.1), but will not exceed 96
subjects. Subjects will be recruited from the volunteers' pool of the trial site.
Only male subjects will be included into the study because hitherto no data on reproductive 
toxicology are available.

adverse events (AEs), or diseases)
4. 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.
5. The subject shows an elevation of AST and/or ALT ≥3-fold ULN combined with an 
elevation of total bilirubin ≥2-fold ULN (measured in the same blood sample) and/or 
needs to be followed up according to the ‘DILI checklist’ provided in the ISF.
6.
The subject shows at one dose level a raised CRP level of >3.00 mg/dL or an baseline 
Erythrocyte Sedimentation Rate (ESR) of ≥ 20 millimeters/hour.
In addition to these criteria, the physician may discontinue subjects at any time based on his 
or her clinical judgment.
A subject can also be removed from the trial if eligibility criteria are being violated or if the 
subject fails to comply with the protocol (for instance, by non-adherence to dietary rules, or 
non-attendance at study assessments). This is in particular to be checked before second 
dosing of the FE part.
If a subject is removed from or withdraws from the trial prior to first administration of trial 
medication, the data of this subject will not be entered in the case report form (CRF) or trial 
database and will not be reported in the clinical trial report (CTR). If a subject is removed 
from or withdraws from the trial after first administration of trial medication, this will be 
documented and the reason for discontinuation must be recorded in the CRF. In this case, the 
data will be included in the CRF/trial database and will be reported in the CTR. At the time 
of discontinuation a complete end of trial examination will be performed if possible and the 
information will be recorded in the CRFs. If the discontinuation occurs before the end of the 
REP (see Section 5.2.2.2), the discontinued subject should if possible be questioned for AEs 
and concomitant therapies at or after the end of the REP in order to ascertain collection of 
AEs and concomitant therapies throughout the REP, if not contrary to any consent 
withdrawal of the subject. These discontinuations will be discussed in the CTR.

3.3.4.2
Discontinuation of the trial by the sponsor
Boehringer Ingelheim reserves the right to discontinue the trial overall or at a particular trial 
site at any time for any of the following reasons:
1. New toxicological findings or serious adverse events invalidate the earlier positive 
benefit-risk-assessment. More specifically, the trial will be terminated if more than 50% 
of the subjects show drug-related and clinically relevant adverse events of moderate or 
severe intensity, or if at least one drug-related serious adverse event is reported.
2. The expected enrolment goals overall or at a particular trial site are not met
3. Violation of GCP, or the CTP, or the contract with BI by a trial site or investigator, 
disturbing the appropriate conduct of the trial
4. The sponsor decides to discontinue the further development of the investigational 
product.
5. Dose escalation will be stopped as soon as at least 2 subjects at one dose level on active 
drug showed relevant individual QT prolongation, i.e. a QTc increase of greater 60 ms 
from baseline in connection with absolute QT or QTc greater than 500 ms, which has 
been confirmed by a repeat ECG recording.
6. Dose escalation will be stopped if the estimated exposure is expected to exceed a Cmax of 
1960 nM or anAUC0-24h of 26300 nM*h. Estimation will be done based on preliminary
mean values of AUC0-24h and Cmax of preceding dose groups (see Section 7.3.4).
7. Dose escalation will be stopped, as soon as at least 2 subjects at one dose level showed a 
sustained decrease in systolic blood pressure of over ≥ 20 mmHg for at least 2 hours after 
drug administration compared to baseline (Day 1, predose) which will be measured after 
15 min in supine position (to avoid false positive signals because of the required 
prolonged resting period after drug intake).
The investigator / the trial site will be reimbursed for reasonable expenses incurred in case of 
trial termination (except in case of the third reason).
3.3.5
Replacement of subjects
In case some subjects do not complete the trial, the trial clinical monitor together with the 
trial pharmacokineticist and the trial statistician are to decide if and how many subjects will 
be replaced. A replacement subject will be assigned a unique study subject number, and will 
be assigned to the same treatment as the subject 
 replaces.

4.1.2
Method of assigning subjects to treatment groups
Prior to the screening visit, subjects will be contacted in writing and informed about the 
planned visit dates. The subjects willing to participate will be recruited to dose groups 
according to their temporal availability. As soon as enough subjects have been allocated to 
one of the dose cohorts (3 cohorts per dose group), the following subjects will be allocated to 
one of the other dose cohorts. Therefore, the allocation of subjects to dose cohorts is not 
influenced by trial personnel, but only by the subjects’ temporal availability. As the study 
includes healthy subjects from a homogenous population, relevant imbalances between the 
dose groups are not expected.
The randomisation list with study subject numbers and allocated treatments (SRD part) or 
treatment sequences (FE part) will be provided to the trial site in advance. The allocation of 
subjects to study subject numbers will be performed prior to the first administration of trial 
medication. For this purpose, the subjects will be allocated to a study subject number by the 
method ‘first come first served’. Once a subject number has been assigned, it cannot be 
reassigned to any other subject.
The randomisation procedure is described in Section 7.5.
4.1.3
Selection of doses in the trial
For the SRD part, oral doses in the range of 3 mg to 200 mg have been selected in order to 
assess the safety and tolerability of BI 1358894 in healthy male volunteers, and to investigate 
the PK of this novel TRPC 4/5 inhibitor. The doses selected for this trial cover the 
subtherapeutic, as well as the estimated therapeutic range and potentially supra-therapeutic 
doses within the levels determined by toxicological investigations (see Section 1.2).
For the FE part, oral doses may range from 25 mg to 100 mg.. The dose strengths to be tested 
will (lowest and highest dose) be re-evaluated after explorative safety and PK analysis. The 
FE part will assess the intra-individual food effect, tablet fasted versus tablet fed, of BI 
1358894 in healthy male volunteers, with the aim to cover a dose range suitable for the 
subsequent clinical development.
4.1.4
Drug assignment and administration of doses for each subject
The treatments to be evaluated are outlined in Table 4.1.4: 1 below. The number of units // 
dose volume for placebo corresponds to the number of units // dose volume of the respective
dose level.

otherwise. Administration will be performed following an overnight fast, which is to start no 
later than 10 h before the scheduled dosing. 
In treatment T1, a high-fat, high-calorie breakfast will be served 30 min before drug 
administration. The breakfast must be completely consumed prior to drug administration. The

The total caloric content will be supplied approximately as following: 150 kcal as protein, 250 
kcal as carbohydrate, and 500 to 600 kcal as fat. 
Subjects will be kept under close medical surveillance until 48 h (SRD part) following drug 
administration. During the first 2 h after drug administration, subjects of the SRD are not 
allowed to lie down (i.e. no declination of the upper body of more than 45 degrees from 
upright posture except for medical examination), or to sleep. During the first 4 hours after 
drug administration, subjects of the FE part will only be allowed to lie down if supine 
positioning is required for trial-related measurements (e.g. recording of 12-lead ECG). For 
restrictions with regard to diet, see Section 4.2.2.2.

Blinding and procedures for unblinding
4.1.5.1
Blinding
SRD part
The treatments administered (active or placebo) will be single-blind (blinded to subjects 
only). However, the current dose level will be known to the subjects. 
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.
FE part
The FE part of this Phase I trial will be handled in an open fashion throughout (that is, during 
the conduct, including data cleaning and preparation of the analysis). This is considered 
acceptable because the potential for bias seems to be low and does not outweigh practical 
considerations.
4.1.5.2
Procedures for emergency unblinding
As this trial will be conducted single blinded (single rising dose part) and open-label (food 
effect part), the treatment information will be known to the investigator. Therefore, no 
emergency envelopes will be provided.
4.1.6
Packaging, labelling, and re-supply
Drug supplies will be provided by the Department of Pharmaceutical Development of 
Boehringer Ingelheim Pharma GmbH & Co. KG, Biberach, Germany.
The clinical trial supply consists of containers holding the trial medication which are labelled 
with trial identification. The required information according to the German Drug Law as well 
as Annex 13/EU GMP Guideline will be provided on the containers. Smaller bottles/boxes 
within the clinical trial supply containers will be labelled with:

BI trial number

Name of product and strengths or identification code

Pharmaceutical dosage form, quantity of dosage units 

Route and mode of administration

Term ‘For Clinical Trial Use’ (domestic language)

Sponsor name and address

Storage conditions

Use-by date

Subject number (only SRD part)

Batch number
The telephone number of the sponsor and name, address and telephone number of the trial 
site are given in the subject information form. The EudraCT number is indicated on the title 
page of this protocol as well as on the subject information and informed consent forms.

correct temperature. If the storage conditions are found to be outside the specified range, the 
local clinical monitor (as provided in the list of contacts) is to be immediately contacted.
4.1.8
Drug accountability
The investigator / pharmacist / investigational drug storage manager will receive the 
investigational drugs delivered by the sponsor when the following requirements are fulfilled:

Approval of the trial protocol by the IRB / ethics committee

Availability of a signed and dated clinical trial contract between the sponsor and the 
head of the trial 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 Form 1572
Only authorised personnel as documented in the form ‘Trial Staff List’ may dispense 
medication to trial subjects. The trial medication must be administered in the manner 
specified in the CTP. All unused medication will be disposed locally by the trial site upon 
written authorisation by the clinical monitor. Receipt, usage and disposal must be 
documented on the respective forms. Account must be given for any discrepancies. 
The investigator / pharmacist must maintain records of the product’s delivery to the trial site, 
the inventory at the site, the use by each subject, and the disposal of unused products. 
These records will include dates, quantities, batch / serial numbers, expiry (‘use-by’) dates, 
and the unique code numbers assigned to the investigational products and trial subjects. The 
investigator / pharmacist will maintain records that document adequately that the subjects 
were provided the doses specified by the CTP, and that reconcile all investigational products 
received from the sponsor. At the time of disposal, the investigator / pharmacist must verify 
that all unused or partially used drug supplies have been returned by the clinical trial subject 
and that no remaining supplies are in the investigator’s possession.

OTHER TREATMENTS, EMERGENCY  PROCEDURES,
RESTRICTIONS
4.2.1
Other treatments and emergency procedures
In case of adverse events in need of treatment, the investigator can authorize symptomatic 
therapy. 
In case of alterations of blood pressure (hypotension) and heart rate (tachycardia), which 
were reported in toxicology studies (see section 1.2.2) physical interventions will be the first 
treatment of symptoms. If not successful, appropriate drug therapy will be initiated according 
to common guidelines and algorithms trained in emergency trainings. Dependent on 
individual symptoms, for the treatment of tachycardia this may include intravenous

administration of beta blockers or appropriate antiarrhythmic drugs. For the treatment of 
hypotension, beside volume substitution, administration of vasopressors may be a further 
step. The whole staff of the trial site assuming medical responsibility during conduct of the 
study is routinely trained in emergency procedures.
If required, any subject with an adverse event in need of treatment will be kept under 
supervision at the trial site or transferred to a hospital until all medical evaluation results have 
returned to an acceptable level.
4.2.2
Restrictions
4.2.2.1
Restrictions regarding concomitant treatment
In principle, no concomitant therapy is allowed. All concomitant or rescue therapies will be 
recorded (including time of intake on study days) on the appropriate pages of the CRF.
4.2.2.2
Restrictions on diet and life style
While admitted to the trial site, the subjects are restricted from consuming any other foods or 
drinks than those provided by the staff. Standardised meals will be served at the time points 
described in the Flow Chart. For the SRD, no food is allowed for at least 4 h after drug 
intake.
From 1 h before drug intake until lunch, fluid intake is restricted to the milk served with 
breakfast (FE part Treatment T, see Table 4.1.4: 2), the water administered with the drug, and 
an additional 240 mL of water served on Day 1 at 2 h and 4 h post-dose (mandatory for all 
subjects).

Assessment of adverse events
5.2.2.1
Definitions of adverse events
Adverse event
An adverse event (AE) is defined as any untoward medical occurrence in a patient or clinical 
investigation subject administered a medicinal product and which does not necessarily have 
to have a causal relationship with this treatment.
An AE can therefore be any unfavourable and unintended sign (including an abnormal 
laboratory finding), symptom, or disease temporally associated with the use of a medicinal 
product, whether or not considered related to the medicinal product.
Serious adverse event
A serious adverse event (SAE) is defined as any AE which fulfils at least one of the 
following criteria:


results in death, 

is life-threatening, which refers to an event in which the patient was at risk of death 
at the time of the event; it does not refer to an event that hypothetically might have 
caused death if more severe,

requires inpatient hospitalisation or 

requires prolongation of existing hospitalisation,

results in persistent or significant disability or incapacity, or

is a congenital anomaly/birth defect, or 

is deemed serious for any other reason if it is an important medical event when based 
upon appropriate medical judgment which may jeopardise the patient and may 
require medical or surgical intervention to prevent one of the other outcomes listed in 
the above definitions.
Examples of such events are intensive treatment in an emergency room or at home for 
allergic bronchospasm, blood dyscrasias or convulsions that do not result in hospitalisation or 
development of dependency or abuse. 
AEs considered ‘Always Serious’
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 Section 5.2.2.2, 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. These events should 
always be reported as SAEs as described above.
Adverse events of special interest (AESIs)
The term AESI relates to any specific AE that has been identified at the project level as being 
of particular concern for prospective safety monitoring and safety assessment within this trial, 
e.g. the potential for AEs based on knowledge from other compounds in the same class. 
AESIs need to be reported to the sponsor’s Pharmacovigilance Department within the same 
timeframe that applies to SAEs, please see above.
The following are considered as AESIs in this trial:

Hepatic injury, as defined by the following alterations of hepatic laboratory 
parameters: 
o
an elevation of AST and/or ALT ≥3-fold ULN combined with an elevation of 
total bilirubin ≥2-fold ULN measured in the same blood sample, and/or
o
aminotransferase (ALT, and/or AST) elevations ≥10 fold ULN

These lab findings constitute a hepatic injury alert and the patients showing these lab 
abnormalities need to be followed up according to the ‘DILI checklist’ provided in the 
ISF. In case of clinical symptoms of hepatic injury (icterus, unexplained 
encephalopathy, unexplained coagulopathy, right upper quadrant abdominal pain, 
etc.) without lab results (ALT, AST, total bilirubin) available, the Investigator should 
make sure these parameters are analysed, if necessary in an unscheduled blood test. 
Should the results meet the criteria of hepatic injury alert, the procedures described in 
the DILI checklist should be followed.
Intensity of AEs
The intensity of the AE should be judged based on the following:
Mild:
Awareness of sign(s) or symptom(s) that is/are easily tolerated
Moderate:
Enough discomfort to cause interference with usual activity
Severe:
Incapacitating or causing inability to work or to perform usual activities
Causal relationship of AEs
Medical judgment should be used to determine the relationship, considering all relevant 
factors, including pattern of reaction, temporal relationship, de-challenge or re-challenge, 
confounding factors such as concomitant medication, concomitant diseases and relevant 
history.
Arguments that may suggest that there is a reasonable possibility of a causal relationship 
could be:

The event is consistent with the known pharmacology of the drug 

The event is known to be caused by or attributed to the drug class.

A plausible time to onset of the event relative to the time of drug exposure.

Evidence that the event is reproducible when the drug is re-introduced

No medically sound alternative aetiologies that could explain the event (e.g. pre-
existing or concomitant diseases, or co-medications).

The event is typically drug-related and infrequent in the general population not 
exposed to drugs (e.g. Stevens-Johnson syndrome).

An indication of dose-response (i.e. greater effect size if the dose is increased, smaller 
effect size if dose is diminished).
Arguments that may suggest that there is no reasonable possibility of a causal relationship 
could be:

No plausible time to onset of the event relative to the time of drug exposure is evident 
(e.g. pre-treatment cases, diagnosis of cancer or chronic disease within days / weeks 
of drug administration; an allergic reaction weeks after discontinuation of the drug 
concerned)

Continuation of the event despite the withdrawal of the medication, taking into 
account the pharmacological properties of the compound (e.g. after 5 half-lives). Of 
note, this criterion may not be applicable to events whose time course is prolonged 
despite removing the original trigger.


Additional arguments amongst those stated before, like alternative explanation (e.g. 
situations where other drugs or underlying diseases appear to provide a more likely 
explanation for the observed event than the drug concerned).

Disappearance of the event even though the trial drug treatment continues or remains 
unchanged. 
5.2.2.2
Adverse event collection and reporting
AEs collection
Upon enrolment into a trial, the subject’s baseline condition is assessed (for instance, by 
documentation of medical history/concomitant diagnoses), and relevant changes from 
baseline are noted subsequently. 
Subjects will be required to report spontaneously any AEs as well as the time of onset, end, 
and intensity of these events. In addition, each subject will be regularly assessed by the 
medical staff throughout the clinical trial and whenever the investigator deems necessary. As 
a minimum, subjects will be questioned for AEs (and concomitant therapies) at the time 
points indicated in the Flow Chart. Assessment will be made using non-specific questions 
such as ‘How do you feel?’ Specific questions will be asked wherever necessary in order to 
more precisely describe an AE.
A careful written record of all AEs shall be kept by the investigator in charge of the trial. 
Records of AEs shall include data on the time of onset, end time, and intensity of the event as 
well as any treatment or action required for the event and its outcome.
The following must be collected and documented on the appropriate CRF(s) by the 
investigator:

From signing the informed consent onwards  until an individual subject’s end of trial: 
o
All AEs (serious and non-serious) and all AESIs.
o
The only exception to this rule are AEs (serious and non-serious) and AESIs 
in Phase I trials in healthy volunteers, when subjects discontinue from the trial 
due to screening failures prior to administration of any trial medication. In 
these cases, the subjects’ data must be collected at trial site but will not be 
entered in the CRF or trial database and will not be reported in the CTR.

After the individual subject’s end of trial: 
o
The investigator does not need to actively monitor the subject for AEs but 
should only report related SAEs and related AESIs of which the investigator 
may become aware of by any means of communication, e.g. phone call. Those 
AEs should, however, not be reported in the CRF.

The REP for BI 1358894, when measurable drug levels or PD effects are still likely to be 
present after the last administration, is not known for this first-in-human trial. Therefore, all 
AEs reported until the end of trial examination (last per protocol contact) will be considered 
on treatment (please see Section 7.3.3).
AE reporting to sponsor and timelines
The Investigator must report SAEs, AESIs, and non-serious AEs which are relevant for the 
reported SAE or AESI, on the BI SAE form via fax immediately (within 24 hours of 
awareness) to the sponsor’s unique entry point (country specific contact details will be 
provided in the ISF). The same timeline applies if follow-up information becomes available. 
In specific occasions the Investigator could inform the sponsor upfront via telephone. This 
does not replace the requirement to complete and fax the BI SAE form.
With receipt of any further information to these events, a follow-up SAE form has to be 
provided. For follow-up information the same rules and timeline apply as for initial 
information.
Information required
For each AE, the investigator should provide the information requested on the appropriate 
eCRF pages and the BI SAE form, if applicable. The investigator should determine the causal 
relationship to the trial medication. 
The following should also be recorded as an (S)AE in the CRF and BI SAE form (if 
applicable):

Worsening of the underlying disease or of other pre-existing conditions 

Changes in vital signs, ECG, physical examination and laboratory test results, if they 
are judged clinically relevant by the investigator.
If such abnormalities already pre-exist prior to trial inclusion they will be considered as 
baseline conditions and should be collected in the eCRFonly.
All (S)AEs, including those persisting after individual subject’s end of trial must be followed 
up until they have resolved, have been , assessed as ‘chronic’ or ‘stable’, or no further 
information can be obtained.

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

5.2.4.1
12-lead resting ECG
Twelve-lead resting ECGs (I, II, III, aVR, aVL, aVF, V1 - V6) will be recorded using a 
computerised electrocardiograph (CardioSoft EKG System, 
 
) at the time points given in the Flow Chart.
In order to achieve a stable heart rate at rest and to assure high quality recordings at 
comparable resting phases, all ECGs will be recorded for a 10-second duration after the 
subjects have rested for at least 5 minutes in a supine position. The site personnel will be 
instructed to assure a relaxed and quiet environment so that all subjects are at complete rest 
during the recordings. ECG assessment will always precede all other study procedures of the 
same time point (except blood drawing from an intravenous cannula which is already in 
place) to avoid impact of sampling on the ECG quality.
Electrode placement will be performed according to the method of Wilson, Goldberger and 
Einthoven modified by Mason and Likar (hips and shoulders instead of ankles and wrists). 
Precise electrode placement will be marked with an indelible mark on the skin to allow 
reproducible placement throughout the study.
Single rising dose part: Triple ECGs will be recorded (within 180 sec) at all-time points as 
specified in the respective Flow Chart. At all remaining time points, single ECGs will be 
recorded.
Food effect part: Single ECGs will be recorded for all time points. However, the number of 
ECGs per time point may be increased to three ECGs based on preliminary ECG results 
obtained during the single rising dose part of the study.
All locally printed ECGs will be evaluated by the investigator or a designee..
ECGs may be repeated for quality reasons (like alternating current artefacts, muscle 
movements, electrode dislocation). For time points with triple ECGs, all three single ECGs 
will be repeated. For the repeats due to quality reasons, only the repeated ECG recordings 
will be sent to the central ECG lab, whereas the initially recorded ECGs will be discarded.
Additional (unscheduled) ECGs may be collected by the investigator for safety reasons. 
These ECGs are assigned to the prior scheduled time point. Unscheduled ECGs will not be 
included into the statistical analysis of interval lengths.
For the inclusion or exclusion (see Section 3.3) of a subject and for the assessment of cardiac 
safety during the study, the QT and QTcB values generated by the ECG machines or their 
manual corrections by the investigators will be used. In doubtful cases, ECGs may be sent 
upfront for centralised evaluation (see below). In this case, these centrally measured results 
would overrule any other results obtained.

Abnormal findings will be reported as AEs (during the trial) or baseline conditions (at 
screening), if judged clinically relevant by the investigator. Any ECG abnormalities will be 
monitored carefully and, if necessary, the subject will be removed from the trial and will 
receive the appropriate medical treatment.
Assessed ECGs will comply with the ICH E14 guidance document and supplements 
[R05-2311, R13-0801, R13-4095] as well as the FDA requirements for annotated digital 
ECGs [R09-4830].
5.2.4.2
Continuous ECG monitoring
Cardiac rhythm (including heart rate) will be monitored (only during SRD part) by means of 
continuous 3-lead ECG recording for at least 15 min before (for baseline assessment), and 4 h 
following drug administration using patient monitors (e.g. ApexPro Telemetry System).

Assessment of other safety parameters
5.2.5.1
Vital signs
Systolic and diastolic blood pressures (BP) as well as pulse rate (PR) will be measured by a 
blood pressure device
) at the times 
indicated in the Flow Chart, after subjects have rested for at least 5 min in a supine position. 
All recordings should be made using the same type of blood pressure recording instrument on 
the same arm if possible. Respiratory rate (RR) will be measured after 5 minutes of rest in 
supine position for at least 1 minute.
5.2.5.2
Orthostatic tests
Orthostatic tests will be performed at the time points indicated in the Flow Chart. Subjects 
should have spent at least 5 min in the supine position before blood pressure and pulse rate 
are measured the first time. A further 2 measurements will be performed immediately after 
standing up and after 3 min in a standing position. The measurements will be performed 
using the blood pressure device described in Section 5.2.5.1. The term “Orthostatic 
dysregulation” will be used to describe adverse events that occur during orthostatic testing. 
Typical symptoms (and findings) of orthostatic dysregulation are Orthostatic hypotension is 
defined as a reduction in systolic BP of ≥20 mm Hg or in diastolic BP of ≥10 mm Hg within 
3 minutes of standing and will be recorded as an AE. Orthostatic hypotension may be 
accompanied by symptoms of dizziness, diaphoresis, a decline in blood pressure, tachycardia 
(PR >100 bpm), or even fainting (which is reflected in the assessment of AE intensity). At 
the time points given in the Flow Chart (MRD part), the following sequence of measurements 
should be adhered to: 12 lead-ECG and vital signs will be done before blood sampling; 
orthostatic testing will be done after blood sampling. While standing up, subjects will be 
accompanied by staff. The timing of orthostatic testing may be adapted based on information 
obtained during the trial (e.g. preliminary PK data (tmax), including reducing or adding 
measurements. This would be implemented via a non-substantial CTP amendment.
5.2.5.3
Visual Analogue Scale (VAS)
Possible psychedelic effects will be monitored and evaluated as safety measurement by 
analogue scales developed by Bond and Lader [R98-0752] and Bowdle along with PK 
sampling. From these measurements, following factors are derived - external and internal 
perception, alertness, mood and calmness. 
The VAS assessments 2 hours before drug administration will be considered as baseline. At 
each measuring time point indicated in the Flow Chart, the subjects will assess their 
subjective impression by themselves by means of a visual analogue scales. The subjects will 
be asked to mark an adequate position on a line between the two limits characteristics. The 
length of the line will be exactly 100 mm, and will ascertain a score number (values between

marked by the subject. The score will be documented in the electronic case report form. 
The original English version is shown in Appendix 10.1.
5.2.5.4
Medical examinations
At screening, the medical examination will include demographics including height and body 
weight, smoking and alcohol history, relevant medical history and concomitant therapy, 
review of inclusion and exclusion criteria, review of vital signs (BP, PR, RR), 12-lead ECG, 
laboratory tests, and a physical examination. At the end of trial examination, it will include 
review of vital signs, 12-lead ECG, laboratory tests, and a physical examination and body 
weight.
5.2.5.5
Suicidality assessment
Suicidality assessment to further evaluate the psychological status of the subject will be 
performed at screening, as indicated in the Flow Chart using the Columbia Suicidal Severity 
Rating scale C-SSRS.
The C-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 Columbia Suicidal Severity Rating scale is shown in Appendix 10.3.
5.2.5.6
Neurological examinations
As a general additional safety measure in the planned dose group 200mg fed a physical 
neurological examination will be performed at the time points specified in the respective 
Flow Chart.
The neurological examination will include the following assessments:
-
General level of arousal
-
Orientation
-
Eye movement
-
Pupil size and pupil reactivity
-
Reflexes 
-
Assessment of muscle strength
-
Gait
-
Romberg test

Methods of sample collection
5.5.2.1
Plasma sampling for pharmacokinetic analysis
For quantification of BI 1358894 plasma concentrations, 2.7 mL of blood will be taken from 
an antecubital or forearm vein into a K3-EDTA (tripotassium Ethylenediaminetetraacetic
acid)-anticoagulant blood drawing tube at the times indicated in the Flow Chart. Blood will 
be withdrawn by means of either an indwelling venous catheter or by venipuncture with a 
metal needle.
Sample handling will be described in detail in a separate lab manual.
All samples will be stored at about -20°C or below until transfer to the analytical laboratory.
At a minimum, the sample tube labels should list the following information: BI trial number, 
subject number, visit, and planned sampling time. Further information such as matrix and 
analyte may also be provided.

will be ± 10 min and laboratory tests will be ± 30 min for the first 4 h after trial drug 
administration and ± 30 min thereafter.
If scheduled in the Flow Chart at the same time as a meal, blood sampling, vital signs and 12-
lead ECG recordings have to be done first. Furthermore, if several measurements including 
venipuncture are scheduled for the same time, venipuncture should be the last of the
measurements due to its inconvenience to the subject and possible influence on physiological
parameters except for the orthostatic testing.
The acceptable deviation from the scheduled time for standardized neurological tests
(conducted in Dose Group 200 mg fed) is ± 45 min on day 1, and ± 90 min from day 2 
onwards.
For planned individual plasma concentration sampling times 
 
refer to the Flow Chart. While these nominal times should be adhered to as closely as 
possible, the actual sampling times will be recorded and used for determination of 
pharmacokinetic parameter.
If a subject misses an appointment, it will be rescheduled if possible. The relevance of 
measurements outside the permitted time windows will be assessed no later than at the 
Blinded Report Planning Meeting.

STATISTICAL METHODS AND DETERMINATION OF 
SAMPLE SIZE
7.1
STATISTICAL DESIGN – MODEL
7.1.1
Objectives
The primary objective of this trial is to investigate the safety and tolerability of BI 1358894
by using descriptive statistics for all endpoints comparing active dose groups to placebo. The 
primary endpoint is defined in Section 5.2.1. Inferential statistics is not planned (as explained 
in Section 7.2).
The secondary objective is the exploration of the pharmacokinetics (PK) of BI 1358894. 
Endpoints as specified in Section 5.5.1 will be analysed by descriptive statistics. Secondary 
endpoints as defined in Section 5.5.1.1 will be subjected to analysis of dose proportionality 
by use of the power model. 
7.2
NULL AND ALTERNATIVE HYPOTHESES
SRD part
Safety and tolerability of the different dose groups of BI 1358894 will be determined on the 
basis of the investigational parameters in comparison with placebo. It is not planned to test 
any statistical hypotheses with regard to these variables in a confirmatory sense. Instead, they 
will be described in their entirety and evaluated by descriptive statistical methods.
For the evaluation of the dose proportionality, a two-sided 95% confidence interval of the
slope will be computed. However, the confidence interval will be interpreted according to the 
exploratory character of the study, i.e. as an interval estimate for effects in the present data.
BA part (Food effect evaluation)
The relative bioavailability of BI 1358894 to evaluate the food effect given as tablets under 
fasted conditions (R) compared to BI 1358894 given as tablets under fed conditions (T1) will 
be estimated by the ratios of the geometric means (T1/R). Additionally, their two-sided 90% 
confidence intervals (CIs) will be provided. This method corresponds to the two one-sided t-
tests procedure, each at the 5% significance level. Since the main focus is on estimation and 
not testing, an acceptance range was not specified, that is, no hypothesis will be tested.
7.3
PLANNED ANALYSES
Adherence to the protocol (such as inclusion/exclusion criteria, times of measurement, 
compliance with intake of trial medication, treatment dispensing errors, prohibited 
concomitant medication, completeness and consistency of data) will be checked. Important 
protocol violations (IPVs) will be identified no later than in the Report Planning Meeting and 
provided in the TSAP.

7.3.1
Primary analyses
Analysis of safety and tolerability is described in Section 7.3.3.
7.3.2
Secondary analyses
The PK parameters (refer to Section 5.5.1) will be calculated according to the BI Standard 
Operating Procedure (SOP) ‘Standards and processes for analyses performed within Clinical 
Pharmacokinetics/Pharmacodynamics’ [001-MCS-36-472], current version. 
Plasma 
 concentration data and parameters of a subject will be included in the
statistical pharmacokinetic (PK) analyses if they are not flagged for exclusion due to a 
protocol violation relevant to the evaluation of PK (to be decided no later than in the Report 
Planning Meeting) or due to PK non-evaluability (as revealed during data analysis, based on 
the criteria specified below). Exclusion of a subject’s data will be documented in the CTR.
Relevant protocol violations may be

Incorrect trial medication taken, i.e. the subject received at least one dose of trial 
medication the subject was not assigned to

Incorrect dose of trial medication taken

Use of restricted medications 

The subject has a protocol deviation relevant to the evaluation of relative 
bioavailability. (Whether a protocol deviation is relevant, will be decided no later than 
the Report Planning Meeting.) 
Plasma 
concentrations and/or parameters of a subject will be considered as non-
evaluable, if for example

the subject experienced emesis that occurred at or before two times median tmax of the 
respective treatment (Median tmax is to be determined excluding the subjects 
experiencing emesis),

missing samples/concentration data at important phases of PK disposition curve.
The PK parameter analysis set (PKS) includes all subjects in the Treated Set (TS) who 
provide at least one PK parameter that was not excluded according to the description above.
Assessment of dose proportionality
Dose proportionality will be assessed using the pharmacokinetic endpoints as specified in 
Section 5.5.1.1 (AUC and Cmax). The specific AUC for the analysis will be defined in the 
TSAP.
The basic model for the investigation of dose proportionality will be a power model that 
describes the functional relationship between the dose and PK endpoints.

Based on the estimate for slope parameter (β), a 2-sided 95% CI for the slope will be 
computed. Perfect dose proportionality would correspond to a slope of 1. The assumption of a 
linear relationship between the log-transformed pharmacokinetic endpoint and the log-
transformed dose will be checked.
If dose proportionality over the entire dose range investigated cannot be shown, an attempt 
will be made to identify dose range(s), where dose proportionality can be assumed.
Dose proportionality will be assessed separately for film-coated tablet after fasted and fed 
conditions..
BA part: Investigation of relative bioavailability (food effect evaluation)
Relative bioavailability is primarily to be determined on the basis of the parameters AUC and 
Cmax (cf. Section 5.5) for the dose levels as specified in Section 3.1 (currently planned for 
50mg, 100mg). The specific AUC for the analysis will be defined in the TSAP. Those 
parameters will be ln-transformed (natural logarithm) prior to fitting the model.
The statistical model used for the analysis of AUC and Cmax will be an ANOVA (analysis of 
variance) model on the logarithmic scale. The specific AUC for the analysis will be defined 
in the TSAP. This model will include effects accounting for the following sources of 
variation: ‘sequence’, ‘subjects within sequences’, ‘period’ and ‘treatment’. The effect 
‘subjects within sequences’ will be considered as random, whereas the other effects will be 
considered as fixed. For tests on subject, period, and treatment effects, the denominator sum 
of squares will be the sum of squares for error; while for tests on sequence effects, the 
denominator will be the sum of squares for subjects. The model is described by the following 
equation

yijkm = + i + sim + j + k + eijkm, where
yijkm = logarithm of response measured on subject m in sequence i receiving treatment 
k in period j,
= the overall mean,
i = the ith sequence effect, i = 1, 2

k = the kth treatment effect, k = 1, 2
eijkm = the random error associated with the mth subject in sequence i who received 
treatment k in period j.
The difference between the expected means for test treatments (tablets under fed conditions 
T1) and reference treatment (tablets under fasted conditions R) log(T1)-log(R), will be 
estimated by the difference in the corresponding Least Square Means (point estimate) and 
two-sided 90% confidence intervals based on the t-distribution will be computed. These 
quantities will then be back-transformed to the original scale to give the point estimator 
(geometric mean) and interval estimates for the ratio between response under test and 
response under reference.
7.3.3
Safety analyses
Safety will be assessed for the endpoints listed in Section 5.2.1. All treated subjects (that is,
all subjects who received at least one dose of study drug), will be included in the safety 
analysis. Safety analyses will be descriptive in nature and will be based on BI standards. No 
hypothesis testing is planned.
Treatments will be compared in a descriptive way. The placebo control group in the safety 
evaluation will consist of all placebo treated subjects, regardless of the dose group in which 
they were treated. The active treatment groups will be compared to the placebo group in a 
descriptive way. Tabulations of frequencies/proportions will be used for the evaluation of 
categorical (qualitative) data, and tabulations of descriptive statistics will be used to analyse 
continuous (quantitative) data.
In the SRD part, the active treatment groups will be compared to the placebo control group in 
a descriptive way. In the BA part, the two different treatments will be compared in a
descriptive way. Tabulations of frequencies/proportions will be used for the evaluation of 
categorical (qualitative) data, and tabulations of descriptive statistics will be used to analyse 
continuous (quantitative) data.
The analyses will be done by ‘randomised treatment’.

Measurements (such as ECG, vital signs, or laboratory parameters) or AEs will be assigned to 
treatments (see Section 4.1) based on the actual treatment at the planned time of the 
measurement or on the recorded time of AE onset (concept of treatment emergent AEs). 
Therefore, measurements planned or AEs recorded prior to first intake of trial medication will 
be assigned to 'screening', those between first trial medication intake until the end of trial visit 
will be assigned to the treatment period. These assignments including the corresponding time 
intervals will be defined in detail in the TSAP. Please note that AEs occurring after the last 
per protocol contact but entered before database lock will be reported to drug safety only and 
will not be captured in the trial database.
Adverse events will be coded using the Medical Dictionary for Regulatory Activities 
(MedDRA). Frequency, severity and causal relationship of AEs will be tabulated by 
treatment, system organ class and preferred term. SAEs, AESIs (see Section 5.2.2.1) and 
other significant AEs (according to ICH E3) will be listed separately. 
Laboratory data will be compared to their reference ranges. Values outside the reference 
range as well as values defined as clinically relevant will be highlighted in the listings. 
Additionally, differences from baseline will be evaluated.
Vital signs 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.

7.3.5
Pharmacokinetic analyses
The pharmacokinetic parameters listed in Section 5.5.1 for drug BI 1358894 will be 
calculated according to the BI SOP ‘Standards and processes for analyses performed within 
Clinical Pharmacokinetics/Pharmacodynamics’ [001-MCS-36-472, current version].
Subjects who are not included in the PKS (refer to Section 7.3.1.) will be reported with their 
individual plasma /
concentrations and individual pharmacokinetic parameters; 
however, they will not be included in descriptive statistics for plasma /
concentrations, 
pharmacokinetic parameters or other statistical assessment.
Only concentration values within the validated concentration range will be used for the 
calculation of pharmacokinetic parameters.
 
 
Final PK analyses will use actual sampling times.
 
Concentrations used in the 
pharmacokinetic calculations will be in the same format provided in the bioanalytical report, 
(that is, to the same number of decimal places provided in the bioanalytical report).
If a predose concentration value is greater than 5% of Cmax, the subject’s pharmacokinetic 
data will not be included in any statistical evaluations, in accordance with international 
guidances. The individual pharmacokinetic parameters of such a subject will be calculated 
and listed separately. If a predose concentration is above BLQ, but less than or equal to 5% of 
the subject’s Cmax value, the subject’s data without any adjustments will be included in all 
pharmacokinetic measurements and calculations.

Plasma
drug concentration - time profiles
Handling of missing PK data will be performed according to the relevant SOP of the Sponsor 
[001-MCS-36-472, current version].
Drug concentration data identified with NOS (no sample available), NOR (no valid result), 
NOA (not analysed) or BLQ (below the lower limit of quantificationwill be displayed as such 
and not replaced by zero at any time point (this rule also applies to the lag phase, including
the predose values). 
7.4.3
Pharmacokinetic parameters
Handling of missing PK data will be performed according to the relevant SOP of the Sponsor 
[001-MCS-36-472, current version].
For the non-compartmental analysis, concentration data identified with NOS, NOR or NOA 
will generally not be considered. Concentration values in the lag phase identified as BLQ will 
be set to zero. All other BLQ values of the profile will be ignored. The lag phase is defined as 
the period between time zero and the first time point with a concentration above the 
quantification limit.
7.5
RANDOMISATION
SRD part
The subjects of the first two cohorts per dose level will not be randomised to maintain a 
treatment sequence of active-placebo-active-active due to safety reasons. In the third cohort 
of each dose level the subjects will be assigned to active or placebo treatment using a 3:1 
allocation ratio. 
BA part (food effect evaluation)
Subjects will be randomized to one of the two treatment sequences R/T1, T1/R in a 1:1 ratio. 
The sponsor will arrange for the randomisation as well as packaging and labelling of trial 
medication. The randomisation list will be generated using a validated system, which 
involves a pseudo-random number generator and a supplied seed number so that the resulting 
allocation is both reproducible and non-predictable.
The randomisation list will contain additional blocks to allow for subject replacement (refer 
to Section 3.3.5).
7.6
DETERMINATION OF SAMPLE SIZE
SRD part
It is planned to include a total of up to 64 subjects in this trial. The planned sample size is not 
based on a power calculation. The size of 8 subjects per dose group (6 on active treatment, 
and 2 on placebo) is commonly used in single-rising dose studies of the present type and is in

general considered as sufficient for the exploratory evaluation of single dose safety and 
pharmacokinetics [R95-0013].
Additional subjects may be entered to allow testing of additional doses on the basis of 
experience gained during the trial conduct (e.g. preliminary PK data), provided the planned 
and approved highest dose will not be exceeded. Thus, the actual number of subjects entered 
may exceed 64 but will not exceed 72 subjects entered.
BA part (food effect evaluation)
It is planned to enter a maximum of 24 subjects in this part of the trial: 12 subjects receiving
50mg and 100mg of BI 1358894. With this sample size, a certain precision in estimating the 
ratio of geometric means (test/reference) can be expected with 95% probability. Precision is 
defined through the ratio of upper to lower confidence interval limit. Note that the precision 
is independent of the actual ratio of geometric means.
For this first-in-man study, no information on intra-subject variability is available. Therefore,
Table 7.6: 1 provides an overview on the achievable precision for estimating the ratio of 
geometric means (test/reference) when comparing the formulations for two different gCV.
For illustrative purposes, the expected 90% confidence intervals with 95% coverage 
probability are displayed for different values of geometric means ratios T1/R.

Description of change
Changes apply to several sections throughout the 
protocol and are described only once and not 
repeated for each section:
1. Synopsis and Flow Chart
To further evaluate the psychological status  
of subjects at screening and during the study a 
further visual analogue scale (Bowdle VAS to 
screen for psychedelic effects) has been 
included.
In addition a suicidality assessment scores 
(Columbia-Suicide Severity Rating Scale) will 
be conducted at screening and at EOT. This 
applies also for the FE part.
2. Section 2.3.2.3, Risk minimization (safety 
precautions and stopping rules)
Deferred inclusion of subjects and 
implementation of three cohorts per dose 
groups taking into account safety, tolerability 
and preliminary PK data.
3. Section 3.1, Overall Trial Design and Plan
The dose strength used in the FE part will be 
selected based on the data of the completed 
SRD part.
4. Section 3.3.3, Exclusion criteria
Exclusion criteria no. 1 and 3 have been 
modified to limit the acceptance of selected 
abnormal values by the investigator as not 
clinically relevant.Exclusion criteria number 
23 and 24 have been added (abnormal 
suicidality assessment score)
5. Section 3.3.4.2, Discontinuation of the trial by 
the sponsor
Drug related SAEs will lead to discontinuation 
of the trial, no drug related SAE will be 
considered.
6. Section 4.2.1, Other treatments and 
emergency procedure
Emergency procedures for cardiovascular 
events have been specified.

7. Section 5.2.5.5, Suicidality assessment
Forms of suicidality assessment and Bowdle 
VAS have been added.
Rationale for change
Based on the feedback by BfArM and Ethics 
Committee, the respective recommendations were 
included in a revised protocol. This applies for all 
major changes as summarized in “Section to be 
changed”, such as deferred inclusion of subjects, 
increased efforts for psychological testing and 
modification of exclusion criteria. In context with 
these changes a few remaining inconsistencies 
were also corrected.

Description of change
Changes apply to several sections throughout the 
protocol and are described only once and not 
repeated for each section:
Synopsis and different sections throughout the 
protocol:
The maximum exposure threshold was lowered to 
mean AUC 0-24  of 950 nmol*h/L corresponding  to 
1/10th  of the exposure observed in  male rats at 
7.5 mg/kg/day in the 4-week toxicology study
An additional dose group of 6 mg  
was added. The maximum number of subject 
may increase to 120 in the SRD part.
Section 3.3.3 Exlusion Criteria
C-reactive Protein > ULN and erythrocyte 
sedimentation rate > 15mm/hour are included as 
strict exlusion criteria
Section 3.3.4.1 
C-reactive Protein > 3 mg/dl and erythrocyte 
sedimentation rate > 20mm/hour  are included as 
individual discontinuation criteria
Rationale for change
Based on the feedback by FDA, the respective 
recommendations were included in this revised 
protocol. This applies for most of the changes as 
summarized in “Section to be changed”, such as
lowering of the exposure threshold, modification 
of exclusion criteria and discontinuation criteria
for an individual subject. In context with these 
changes some inconsistencies were also corrected, 
in particular the addition of psychological 
assessments prior to the second dosing of the FE 
part.

Description of change
Changes apply to several sections throughout the 
protocol and are described only once and not 
repeated for each section:
Synopsis and different sections throughout the 
protocol:
The maximum exposure threshold was increased
to geometric mean AUC 0-24  of 9500 nmol*h/L 
corresponding  to the maximum  of the exposure 
observed in  male rats at 7.5 mg/kg/day in the 4-
week toxicology study
Section 3.1 and section 7.3.4
In case of a less than dose proportional increase 
of exposure with a tablet formulation a switch to 
an oral suspension for further dose escalations
may be considered.
Rationale for change
Oral single doses of up to 25 mg were shown to 
be well tolerated. There were no SAEs and no 
AEs considered to be dose limiting. With an oral 
dose of 25 mg we are approaching the predefined 
maximum exposure threshold. Since all currently 
tested dose levels were well tolerated we consider 
it justified to further increase the exposure 
threshold which would allow us to test doses 
beyond 25 mg. We would like to propose an 
increase of the exposure threshold up to the 
NOAEL in rats due to the up to now encouraging 
safety profile in the ongoing Phase I study. We 
would like to highlight that we continue to stop 
dose escalation as soon as safety signal as defined 
in the protocol will be observed. 
In context with these changes a few remaining 
inconsistencies were also corrected.

protocol:
Description of change
Hospitalisation period will be prolonged to 48 h 
instead of 34 hours.
Rationale for change
Based on interim PK-data of the ongoing study 
the preliminary half-life was calculated to be in a 
range of about 40 hours instead of an initially 
predicted human half-life of about 15 hours. 
Because of the longer half-life it is considered 
necessary to extend the observation period to at 
least 48 hours.

Additional dose group in the food effect part
Rationale for change
The ongoing study has recently completed the 
first dose group of the food effect part, using 50 
mg as the initial dose strength. Since preliminary 
PK and safety assessments did not prevent further 
dose escalation the FE part of the study will 
continue with a dose level of 100 mg. Provided 
that the FE part with 100 mg does still not reveal 
dose limiting findings, a further dose group 
beyond 100 mg may enter the FE part. The 
maximum planned dose of the tentative group

- Dose group 200 mg fed will be only conducted, 
if there is an at least 90% probability that the 
estimated individual exposure based on PK of 
preceding dose groups will not exceed the new

Section 6.1
- Definition of time window for neurological 
examination
Rationale for change
The ongoing study has recently completed the 
second dose group of the food effect part, using 
100 mg as dose strength. Safety assessments from 
all dose groups including the most recent 100 mg 
administered under fed conditions did not reveal 
dose limiting safety findings and the mean 
exposure (AUC0-24) remained below the current 
threshold of 9500 nmol*h. A further increase of 
dose beyond 100 mg administered under fed 
conditions requires an adjustment of the exposure 
threshold to the exposure at NOAEL in rats (i.e. 
Cmax of 1960 nM and an AUC0-24 of 26300 
nM*h), which is considered to be the maximum 
possible threshold for an individual exposure in 
healthy subjects. The safety assessments of this 
final dose group have been intensified and the

hospitalisation phase will be extended to Day 7.
In context with these changes a few remaining 
inconsistencies were also corrected, such as the 
deletion of dose levels beyond 200 mg in the SRD 
part (i.e. 400 mg, 600 mg) and 25 mg fed in the 
FE part as well as the oral suspension which will 
no more be tested in this study to the exposure at 
NOAEL in rats (i.e. Cmax of 1960 nM and an 
AUC0-24 of 26300 nM*h), which is considered 
to be the maximum possible threshold for an 
individual exposure in healthy subjects.
