Trial rationale
BI 1358894 has been characterised to be an inhibitor of P-gp, OATP1B1/1B3 and 
BCRP in-vitro. This trial will be performed to test the inhibitory effect of BI 
1358894 on these drug transporters in-vivo. Dabigatran will be used as model 
substrate for P-gp, rosuvastatin as model substrate for BCRP and OATP1B1/1B3.
Trial objective
To investigate the relative bioavailability of 10 mg rosuvastatin (Part 1) and 150 mg 
dabigatran (Part 2) given alone and together with 200 mg BI 1358894
Trial design
Part 1: non-randomised, open-label, two period crossover design 
Part 2: non-randomised, open-label, two period crossover design
Trial endpoints:
Part 1
Primary endpoints: AUC0-and Cmax of rosuvastatin 
Secondary endpoints: AUC0-tz of rosuvastatin  
Part 2
Primary endpoints: AUC0-and Cmax of dabigatran
Secondary endpoints: AUC0-tz of dabigatran 
Number of subjects 
total entered
28 
each treatment
14 in Part 1, 14 in Part 2
In case more than 2 subjects do not complete the respective trial part according to
protocol, up to 6 replacement subjects may be included into each trial part. Thus, a 
maximum of 20 subjects may participate in each trial part.

Period 1: 1 tablet Crestor® 10 mg Filmtabletten
Period 2: 1 tablet Crestor® 10 mg Filmtabletten together with 2 tablets BI 1358894
Treatments are separated by a wash-out period of at least 7 days between study drug 
administrations.
Part 2 (all treatments are given as single dose)
Period 1: 1 capsule Pradaxa® 150 mg Hartkapseln
Period 2: 1 capsule Pradaxa® 150 mg Hartkapseln with 2 tablets BI 1358894
Treatments are separated by a wash-out period of at least 7 days between study drug 
administrations.
Statistical methods
Relative bioavailability will be estimated by the ratios of the geometric means 
(test/reference) for the primary and secondary endpoints. Additionally, their two-
sided 90% confidence intervals (CIs) will be provided. This method corresponds to 
the two one-sided t-test procedure, each at a 5% significance level. Since the main 
focus is on estimation and not testing, a formal hypothesis test and associated 
acceptance range is not specified. The statistical model will be an analysis of 
variance (ANOVA) on the logarithmic scale including effects for subjects and 
treatment. CIs will be calculated based on the residual error from the ANOVA.
Descriptive statistics will be calculated for all endpoints.

INTRODUCTION
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). BI 1358894 has been characterised to be an inhibitor of P-
glycoprotein (P-gp), Breast cancer resistance protein (BCRP) and of the Organic anion 
transporting polypeptides (OATP) 1B1 and 1B3 in-vitro. This trial should investigate, 
whether BI 1358894 is also in-vivo an inhibitor of these drug transporters.  
1.1
MEDICAL BACKGROUND
Major depressive disorder is a debilitating disease characterised by low mood and often by 
low self-esteem, low energy, and a loss of interest. It can strongly impact a person’s life and 
health, including significantly increased risk of suicidality, and is difficult to treat, even with 
systematic antidepressant strategies. In the National Institute of Mental Health 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 
residual symptoms [R16-5475] that 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 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 severely impaired 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, frontal cortex, hippocampus, 
and hypothalamus [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] and there is growing evidence supporting the role of amygdala in the emotion 
processing disturbances observed in patients with BPD [R16-5472].

1.2.2
Rosuvastatin
Rosuvastatin is an HMG-CoA reductase inhibitor indicated for treatment of hypercholesterol-
emia and for prophylaxis of cardiovascular events. Inhibition of HMG-CoA decreases hepatic 
cholesterol production which, in turn, stimulates hepatocellular uptake of low-density 
lipoproteins [R17-2886]. 
After oral administration, maximal rosuvastatin plasma concentrations are reached at ~5 h. 
Oral bioavailability is ~20%, plasma protein binding is ~90%, and volume of distribution is 
~134 L. The liver is a principal compartment of distribution, with hepatocellular uptake being 
mediated mainly by OATP1B1 and, to a lesser degree, by OATP1B3. Elimination is mainly 
via the feces and to a lesser degree, via urine (principally via renal tubular secretion), with a 
t1/2 of 19 h [R17-2886], [P14-07833].
In therapy, the initial rosuvastatin dose is 5-10 mg once daily (q.d.). The daily dose may be 
increased to up to 40 mg [R17-2886].
Adverse reactions to rosuvastatin are normally mild and transient. Myalgia and myopathy 
with concomitant increase of creatine kinase, and, in rare cases, rhabdomyolysis have been 
observed during rosuvastatin therapy. Moreover, as for other HMG-CoA reductase inhibitors, 
a dose-dependent increase of liver transaminases may be observed [R17-2886].
For a more detailed description of the rosuvastatin profile, please refer to the current SmPC
[R19-1574].
1.2.3
Dabigatran 
Pharmacokinetics
Following single dose administration in healthy volunteers, the pharmacokinetic profile of 
dabigatran is characterized by maximum plasma concentration at approximately 1-2 hours 
after oral administration of dabigatran etexilate, a biexponential distribution phase and a 
terminal elimination half-life of about 8-10 hours. With b.i.d. dosing the steady state is 
attained within 3 days, and Cmax at steady state is about 30% higher than after the first dose. 
Dabigatran plasma concentrations and the pharmacokinetic parameters Cmax and AUC 
increased in a dose proportional manner after oral administration of the prodrug dabigatran 
etexilate and after intravenous infusion of dabigatran. The pharmacodynamic parameters 
aPTT, INR, ECT, and TT show close correlation with dabigatran plasma concentrations.
The bioavailability of the dabigatran in the capsule formulation is about 6.5%. After 
treatment with the proton pump inhibitor pantoprazole (increased gastric pH) bioavailability 
is reduced by approximately 20-30%. Co-administration with food results in delay of Cmax 
from 2 to 4 hours; there is no consistent effect on total exposure.

Neither dabigatran etexilate nor dabigatran interacts with CYPs. No drug-drug interactions 
based on CYP dependent pathways have been identified. Dabigatran etexilate but not the 
active moiety, dabigatran, is a substrate of the efflux transporter P-glycoprotein (P-gp). 
Accordingly, the bioavailability of dabigatran is increased when P-gp inhibitors such as 
verapamil, quinidine, amiodarone, dronedarone or ketoconazole are co-administered. 
However this effect could be significantly reduced by staggered administration of the P-gp 
inhibitor. 
Due to rapid hydrolisation only small amounts of dabigatran etexilate reach systemic 
circulation. Thus, modulators of P-gp can affect intestinal absorption of dabigatran etexilate, 
but not its further disposition. Therefore, the staggered administration of a P-gp inhibitor at 
the time point of maximum dabigatran concentration (tmax) will cause a significantly lower 
increase in dabigatran bioavailability, because a great part of the compound has been already 
absorbed from the intestinal lumen. This effect has been proven for the P-gp inhibitors 
dronedarone [U11-2448-01] and verapamil [U09-1052-01], when given 2 h after dabigatran.    
Co-administration of the suggested P-gp inhibitor clarithromycin did not meaningfully affect 
the PK of dabigatran. Rifampicin, an inducer of P-gp reduced the bioavailability of free and 
total dabigatran. Conversely, the PK of co-administered P-gp substrates like digoxin or the 
inhibitors (clarithromycin, verapamil, quinidine, ketoconazole, amiodarone) was not affected 
by dabigatran etexilate confirming the in vitro results that neither dabigatran etexilate nor its 
intermediate metabolites or the active moiety dabigatran are inhibitors of P-gp. 
In the RE-LY study, the effect of concomitant use of verapamil, amiodarone or all potent P-
gp inhibitors on trough and 2 h dabigatran plasma concentrations was assessed descriptively. 
In RE-LY, a greater than 20% increase was not observed when amiodarone, verapamil, 
diltiazem or any strong P-gp inhibitor was co-administered. These findings were qualitatively 
in agreement to the results of the phase I studies though the magnitude of the effect was on 
average much lower in RE-LY. Accordingly, the difference in event rates (i.e., major or any 
bleeding) and efficacy endpoints (stroke, SEE) in patients receiving or not receiving 
verapamil, amiodarone or diltiazem were not pronounced and not clearly different from 
patients treated concomitantly with warfarin and a P-gp inhibitor [U09-3249-02].
Safety 
Dabigatran and dabigatran etexilate were well tolerated by healthy subjects. Overall, more 
than 1000 healthy volunteers have been included in phase I trials with dabigatran etexilate.
Adverse events were few, mild, and included primarily hematoma at the venipuncture site or 
need for prolonged compression for hemostasis on venous catheter removal at higher doses. 
Major bleedings were not observed in the Phase I trials. At the highest dose of dabigatran 
etexilate studied in humans, 400 mg three times daily as oral solution, 6 of 8 subjects reported 
mild bleeding such as hematoma or prolonged bleeding at a venous puncture site, or gingival 
bleeding [U00-1856].
In a further Phase I study [U06-1614-01] single doses of 600 mg, 750 mg, and 900 mg 
HPMC capsules were planned to be administered to find out the highest tolerable dose. After 
600 mg a 2-fold to 3-fold increase in the main coagulation parameter aPTT was achieved at 2 
to 4 h post dose. The only observed AEs were transient abdominal discomfort and a mild

phlebitis at the puncture site in one subject each. The dose levels 750 mg and 900 mg were 
not performed because a full therapeutic effect was already achieved with 600 mg.
For a more detailed description of the dabigatran profile, please refer to the current SmPC
[R18-2734].
1.2.4
Residual Effect Period
Based on an effective half-life of 33 h the Residual Effect Period (REP) of BI 1358894 has 
been determined to be 7 days. The REP for rosuvastatin and dabigatran is approximately 6 
and 3 days, respectively. This is the period after the last dose with relevant measurable drug 
levels and/or pharmacodynamic effects is still likely to be present.
1.3
RATIONALE FOR PERFORMING THE TRIAL
Based on in-vitro data BI 1358894 is an inhibitor of P-gp, BCRP, OATP1B1/1B3. This trial 
will be performed to test the inhibitory effect of BI 1358894 on these drug transporters in-
vivo. Dabigatran will be used as a model substrate of P-gp (Part 2) and rosuvastatin as a 
model substrate of BCRP and OATP1B1/1B3 (Part 1).
1.4
BENEFIT - RISK ASSESSMENT
Participation in this clinical trial is without any (therapeutic) benefit for healthy subjects. 
Their participation, however, is of major importance for the successful clinical development 
of BI 1358894 to improve the treatment of patients with major depressive disorder and 
borderline personality disorder. Subjects are exposed to risks of study procedures and risks 
related to the exposure to the trial medication.
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 related to the administration of rosuvastatin (Part 1)
A single dose of 10 mg rosuvastatin has been well tolerated by healthy subjects in several 
clinical trials [c03246006-01, c08983809-01, c13060859-01]. 
The combined administration of 10 mg rosuvastatin with the OATP1B1/1B3-inhibitor 
rifampin in study 352.2100 increased the rosuvastatin exposure from 6.8 to 77 nmol/L (Cmax) 
and from 94 to 321 nmol/L*h (AUC0-inf.). This increase was well tolerated by healthy subjects 
[c23988236-01]. Comparable effects of rifampin on rosuvastatin exposure have been also 
described by Lai et al [R17-1790] and by Prueksaritanont et al [R15-4771].  
Rifampin is a strong and well characterised inhibitor of OATP1B1/1B3 and is therefore 
recommended for testing OATP inhibition [P12-05791]. Considering this it is assumed, that 
the potential effect of BI 1358894 on the OATP-substrate rosuvastatin does not exceed the 
strong effect of rifampin on rosuvastatin exposure described above. Based on the good 
tolerability observed in study 352.2100 no undue risk to healthy subjects is expected from the 
combined administration of 10 mg rosuvastatin and BI 1358894 in this trial. 
Risk related to the administration of dabigatran (Part 2)
In study 1160.60 a single dose of 600 mg dabigatran etexilate was well tolerated by healthy 
subjects [U06-1614-01]. Taking into account the dose proportional kinetics of dabigatran the 
well tolerated single dose of 600 mg provides a safety margin of 4 to the therapeutic dose of 
150 mg, which is used in Part 2 of this trial.
Dabigatran etexilate is a sensitive substrate of intestinal P-glycoprotein (P-gp). The effect of 
several P-gp inhibitors has been tested in healthy subjects. The strongest effects have been 
seen with a single dose of verapamil (+180% in dabigatran Cmax) and with multiple doses of 
ketoconazole (+150% in dabigatran Cmax und AUC). The observed increase in dabigatran 
exposure has been well tolerated by healthy subjects (1160.74 and 1160.101), which is in line 
with the described safety margin of 4, that has not been exceeded by any P-gp inhibitor.
Verapamil and ketoconazole are well characterized inhibitors of P-gp and therefore 
recommended for testing P-gp inhibition [P12-05791]. Considering that the potential effect of 
BI 1358894 on the P-gp substrate dabigatran etexilate does not exceed the observed strong 
effect of verapamil or ketoconazole on dabigatran exposure and taking into account the 
overall safety margin of 4, which has not been exceeded by any P-gp inhibitor, no undue risk 
to healthy subjects is expected from the combined administration of 150 mg dabigatran 
etexilate and BI 1358894 in this trial.
Drug-induced liver injury (DILI)
Although rare, a potential for drug-induced liver injury (DILI) is under constant surveillance 
by sponsors and regulators. Therefore, this trial requires timely detection, evaluation, and 
follow-up of laboratory alterations in selected liver laboratory parameters to ensure subjects´ 
safety. See also Section 5.2.6.1.4, adverse events of special interest.

Overall assessment
Considering the well characterised safety profile of the marketed drugs dabigatran and 
rosuvastatin, the safety profile observed so far with BI 1358894 and taking into account the 
planned single dose administration of all compounds the sponsor feels that the risk to 
participating subjects are minimised and justified when compared to the potential benefit that 
a successful clinical development of BI 1358894 could provide to the treatment of major 
depressive disorder and borderline personality disorder.

DESCRIPTION OF DESIGN AND TRIAL POPULATION
3.1
OVERALL TRIAL DESIGN AND PLAN
The study consists of 2 trial parts. Each part follows a non-randomised, open-label, two-
period crossover design with a fixed sequence in healthy male subjects in order to compare 
the following test and reference treatments:
Treatments in Part 1

Reference (R1):  tablet Crestor®
 Filmtabletten [rosuvastatin]

Test (T1):  tablet Crestor®
 Filmtabletten together with tablet BI 1358894
Treatments in Part 2

Reference (R2):  capsule Pradaxa®
 Hartkapseln [dabigatran etexilate]

Test (T2):  capsule Pradaxa®
 Hartkapseln together with tablet BI 1358894
All treatments will be given after a high-fat high-calorie breakfast. In both trial parts the 
Reference treatment will always be followed by the Test treatment in a fixed sequence. The
treatment periods are separated by a wash-out phase of at least 7 days between the two drug 
administrations.
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 GROUPS
For relative bioavailability trials, the crossover design is preferred because of its efficiency: 
since each subject serves as his own control, the comparison between treatments is based on 
an intra-subject comparison, thus removing inter-subject variability from the comparison 
between treatments [R94-1529].
Because of the long terminal half-life of BI 1358894 (> 100 h), a fixed-sequence design was 
selected, in which BI 1358894 will be administered in the second study period only. The 
fixed-sequence design is not expected to lead to systematic errors in the estimation of the 
treatment effects since nonspecific time-effects are unlikely due to the short trial duration.
The open-label treatment is not expected to bias results, since the study endpoints are derived 
from measurement of plasma concentrations of the analyte. 
3.3
SELECTION OF TRIAL POPULATION
It is planned that 14 healthy male subjects each will enter either Part 1 or Part 2 of the study. 
They will be recruited from the volunteers' pool of the trial site. In case more than 2 subjects 
do not complete the respective trial part according to protocol, up to 6 replacement subjects 
may be included into each trial part. Thus, a maximum of 20 subjects might participate in 
each trial part.

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 1.2.4), 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. 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

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/her 
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. 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, if at least 2 subjects of the same cohort have drug-related 
severe non-serious adverse events, or if at least 1 drug-related serious adverse event is 
reported
2. Violation of GCP, or the CTP impairing the appropriate conduct of the trial
3. The sponsor decides to discontinue the further development of the investigational product
3.3.5
Replacement of subjects
In case more than 2 subjects do not complete the respective trial part according protocol for 
any reason (including non PK evaluable subjects), the Clinical Trial Leader together with the 
Trial Pharmacokineticist and the Trial Statistician are to decide, if and how many subjects 
will be replaced. The maximum number of replacement subjects is 6 per trial part. Thus the 
total number of exposed subjects will not exceed 20 in each trial part.  A replacement subject 
will be assigned a unique trial subject number.

4.1.2
Selection of doses in the trial
Rosuvastatin and dabigatran are used in standard clinical doses.
In the FIM study 1402-0001 the administration of 
 BI 1358894 (fed conditions)
resulted in an exposure of Cmax = 
 and AUC0-24 = 
 (see 1.2.1). For the 
current trial this dose has been chosen to cover and to exceed the expected therapeutic 
exposure (Cmax,ss of 
 and an AUCss of 
 [c10354149]) to investigate the 
inhibitory effects in a worst-case scenario and to account for potential uncertainties in the 
prediction of the expected therapeutic exposure.
4.1.3
Method of assigning subjects to treatment groups
There is only one treatment sequence investigated in each trial part, and each subject will be 
allocated to the same treatment sequence (R-T). The subjects will be allocated to a study 
subject number by drawing lots prior to first administration of trial medication in the morning 
of Day 1 of Visit 2. Once a subject number has been assigned, it cannot be reassigned to any 
other subject.      
All subjects of the respective study part may be treated in one cohort, i.e. all subjects may 
receive treatment on the same calendar day. In case this is not feasible (e.g., due to logistical 
or recruitment reasons), the group may be split into several cohorts as required. Treatment of 
all subjects on the same calendar day is acceptable (for discussion of study-associated risks 
see Section 1.4).
4.1.4
Drug assignment and administration of doses for each subject
Each trial part follows a two period crossover design. All subjects will receive the 2 
treatments in a fixed sequence (with treatment Reference is always followed by treatment 
Test). The treatments to be evaluated are outlined in the tables below:

The investigator (or authorised designee) will administer the trial medication as an oral dose 
together with about 240 mL of water to subjects who are in a standing 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.
In each treatment period, a high-fat, high-calorie breakfast has to be consumed by the 
subjects within 30 min prior to the planned study drug administration. The composition of the 
standard high-fat, high-calorie breakfast is detailed in Table 4.1.4: 3; 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.

The total caloric content was 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 24 h after drug administration. 
During the first 6 h after drug administration, subjects are not allowed to lie down (i.e. no 
declination of the upper body of more than 45 degrees from upright posture).
The treatments will be separated by a wash-out phase of at least 7 days.
4.1.5
Blinding and procedures for unblinding
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.
Emergency envelopes will not be provided, because the dose of trial medication is known to 
investigators and subjects.
4.1.6
Packaging, labelling, and re-supply
Rosuvastatin and dabigatran will be obtained from a public pharmacy. Both drugs will be 
dispensed out of the original, unmodified packages.

Pipettiertest M-10/14-PDT, or comparable test systems.
FOB plus® test (Part 2 only): The subjects will receive a test tube with an integrated bar for 
stool sampling. On the next occasion they will take three samples from the stool with the 
collection bar and give it into the test tube. The test tubes should be closed carefully to not 
destroy the collection bar. These samples will be analysed for occult blood in faeces by 
immunological reaction according to the manufacturers instruction. As subjects may not be 
able to defecate at the trial site in the morning of the respective visit they may collect the 
specimen at home and bring the test specimen to the trial site.
Laboratory data will be transmitted electronically from the laboratory to the trial site.

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 on the Muse CV Cardiology System (
 
 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). 
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.

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.

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 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.
Adverse events of special interest
5.2.6.1.4
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 are considered as AESIs:


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 encephalo-
pathy, 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.
Intensity (severity) of AEs
5.2.6.1.5
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
Causal relationship of AEs
5.2.6.1.6
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.

DRUG CONCENTRATION MEASUREMENTS AND 
PHARMACOKINETICS
5.3.1
Assessment of pharmacokinetics
For the assessment of pharmacokinetics, blood samples will be collected at the time points 
indicated in the Flow Chart. The actual sampling times will be recorded and used for 
determination of pharmacokinetic parameters. 
5.3.2
Methods of sample collection
5.3.2.1
Blood sampling for pharmacokinetic analysis of rosuvastatin and dabigatran
For quantification of rosuvastatin (Part 1) and dabigatran (Part 2) concentrations in plasma, 
2.7 mL of blood will be drawn from an antecubital or forearm vein into an K2-EDTA 
(dipotassium 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 venepuncture with a metal needle.
The EDTA-anticoagulated blood samples will be centrifuged for approximately 10 min at 
approximately 2000 g to 4000 g and at 4 to 8 °C. Two plasma aliquots will be obtained per 
analyte and stored in polypropylene tubes. The first aliquot should contain at least 0.5 mL of 
plasma. The process from blood collection until transfer of plasma aliquots into the freezer 
should be completed in less than 90 min, with interim storage of blood samples and aliquots 
at room temperature. The time each aliquot was placed in the freezer will be documented.
Until transfer on dry ice to the analytical laboratory, the aliquots will be stored upright at 
approximately -20°C or below at the trial site. At the analytical laboratory, the plasma 
samples will be stored at approximately -20°C or below until analysis.
At a minimum, the sample tube labels should list BI trial number, subject number, visit, and 
planned sampling time. 
After completion of the trial, the plasma samples may be used for further methodological 
investigations (e.g. for stability testing or assessment of metabolites). However, only data 
related to the analyte and/or its metabolite(s) including anti-drug antibodies (if applicable) 
will be generated by these additional investigations. The study samples will be discarded after 
completion of the additional investigations but not later than 5 years after the CTR is 
archived. It is planned to use the back-up samples (2nd aliquots of rosuvastatin and dabigatran 
samples) to get a profile of BI 1358894. Therefore, the second aliquot will be transferred to 
the analytical laboratory for BI 1358894 analytics after confirmation of TCPK.
5.3.2.2
Blood sampling for pharmacokinetic analysis of BI 1358894 and BI 1361608
For quantification of BI 1358894 and BI 1361608 (Part 1 and 2) concentrations in plasma, 
2.7 mL of blood will be drawn from an antecubital or forearm vein into an K2-EDTA 
(dipotassium 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 venepuncture with a metal needle.

Pharmacogenomic evaluation
Pharmacogenomic investigations explore the role of genetic variation in determining an 
individual’s response to drugs. For this purpose, a sample of at most 10 mL of blood will be 
obtained at the screening examination from each subject whose genotype has not been 
previously determined. Separate informed consent for genotyping will be obtained from each 
volunteer prior to sampling.
DNA will be extracted from the blood sample in order to sequence genes coding for proteins 
that are involved in the absorption, distribution, metabolism, and excretion (ADME) of drugs. 
The gene sequences to be determined include known and likely functional variations of key 
ADME genes and incorporate more than 90% of ADME-related genetic markers identified by 
the Pharma ADME group (weblink.pharmaadme.org). It is not intended to include the 
pharmacogenomic data in the CTR. However, the data may be part of the CTR, if necessary.
5.7
APPROPRIATENESS OF MEASUREMENTS
All measurements performed during this trial are standard measurements and will be 
performed in order to monitor subjects’ safety and to determine pharmacokinetic parameters 
in an appropriate way. The scheduled measurements will allow monitoring of changes in vital 
signs, standard laboratory values, and ECG parameters that might occur as a result of 
administration of trial medication. The safety assessments are standard, are accepted for 
evaluation of safety and tolerability of an orally administered drug, and are widely used in 
clinical trials. The pharmacokinetic parameters and measurements outlined in Section 5.4 are 
generally used assessments of drug exposure.

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, and laboratory tests will be 
± 60 min.
Starting from a planned time of 48 hours after drug administration (and beyond) a time 
window of +/- 120 minutes will be allowed for all procedures.
If scheduled in the Flow Chart at the same time as a meal, blood sampling, vital signs recor-
dings 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.
The subjects may have their dinner together in all trial periods.
If a subject misses an appointment, it will be rescheduled if possible. The relevance of 
measurements outside the permitted time windows will be assessed no later than at the Report 
Planning Meeting.
6.2
DETAILS OF TRIAL PROCEDURES AT SELECTED VISITS
6.2.1
Screening
After having been informed about the trial, all subjects will provide written informed consent 
in accordance with GCP and local legislation prior to enrolment in the study.
For information regarding laboratory tests (including drug and virus screening), ECG, vital 
signs, and physical examination, refer to Sections 5.2.3 to 5.2.5.
Genotyping will be performed in those volunteers whose genotypes have not been previously 
determined (for details, see Section 5.3).
6.2.2
Treatment period
Each subject is expected to participate in 2 treatment periods (Part 1: Days 1-5 in each period, 
Part 2: Day 1-4 in each period). In both trial parts at least 7 days will separate drug 
administrations in the first and second treatment period.

On Day 1 of each treatment period, study participants will be admitted to the trial site and 
kept under close medical surveillance for at least 24 h following drug administration. 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 5.3
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 EoTrial 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 EoTrial 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
The main objective of this trial is to investigate the relative bioavailability of 
 
rosuvastatin (Part 1, Reference 1) and 
 dabigatran (Part 2, Reference 2) given alone 
compared to a combined administration with 
 BI 1358894 (Part 1 - Test 1, Part 2 -
Test 2) following oral administration on the basis of the primary and secondary 
pharmacokinetic endpoints, as listed in Sections 2.1.2 and 2.1.3. Both trial parts are designed 
to allow intra-subject comparisons and will be evaluated statistically by use of a linear model 
for logarithmically transformed PK endpoints. 
A further objective is to evaluate and compare further pharmacokinetic parameters between 
the treatments. These pharmacokinetic parameters will be assessed by descriptive statistics.
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 2.2.2.3.
7.2
NULL AND ALTERNATIVE HYPOTHESES
The relative bioavailability of rosuvastatin (Part 1) / dabigatran (Part 2) given alone 
compared with a combined administration with BI 1358894 will be estimated by the ratios of 
the geometric means (test/reference), and their corresponding 2-sided 90% confidence 
intervals (CIs) will be provided. This method corresponds to the two one-sided t-test 
procedure, each at the 5% significance level. Since the main focus is on estimation and not 
testing, a formal hypothesis test and associated acceptance range is not specified.
7.3
PLANNED ANALYSES
Analysis sets
Statistical analyses will be based on the following analysis sets:

Treated set (TS): The treated set includes all subjects who were entered and treated 
with at least one dose of study drug. The treated set will be used for safety analyses.
Pharmacokinetic analysis set (PKS): This set includes all subjects in the treated set 
(TS) who provide at least one PK endpoint that was defined as primary or secondary 
and was not excluded due to a protocol deviation relevant to the evaluation of PK or 
due to PK non-evaluability (as specified in the following subsection 
‘Pharmacokinetics’). Thus, a subject will be included in the PKS, even if he 
contributes only one PK parameter value for one period to the statistical assessment.
Descriptive and model based analyses of PK parameters will be based on the PKS.
Adherence to the protocol will be assessed by the trial team. Important protocol deviation 
(IPD) categories will be suggested in the IQRM plan, IPDs will be identified no later than in 
the Report Planning Meeting, and the IPD categories will be updated as needed.

Pharmacokinetics
The pharmacokinetic parameters listed in Section 2.1 for rosuvastatin, dabigatran, BI 
1358894 and BI 1361608 will be calculated according to the relevant SOP of the Sponsor 
(001-MCS-36-472). 
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 
deviation 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 deviations 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
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),

A predose concentration is >5% Cmax value of that subject

Missing samples/concentration data at important phases of PK disposition curve
Plasma concentration data and parameters of a subject which is flagged for exclusion will be 
reported with its individual values but will not be included in the statistical analyses. 
Descriptive and inferential statistics of PK parameters will be based on the PKS.
Only concentration values within the validated concentration range and actual sampling times 
will be used for the calculation of pharmacokinetic parameters. Concentrations used in the 
pharmacokinetic calculations will be in the same format provided in the bioanalytical report, 
(that is, to the same number of decimal places provided in the bioanalytical report). 
7.3.1
Primary endpoint analyses
Primary analyses
The primary endpoints (refer to Section 2.1.2) 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).
The statistical model used for the analysis of the primary endpoints will be an analysis of 
variance (ANOVA) model on the logarithmic scale. That is, the PK endpoints will be log-
transformed (natural logarithm) prior to fitting the ANOVA model. This model will include 
effects accounting for the following sources of variation: subjects and treatment. The effect

‘subjects’ will be considered as random, whereas ‘treatment’ will be considered as fixed. The 
model is described by the following equation:
ykm = + sm + k + ekm, where
ykm = logarithm of response measured on subject m receiving treatment k,
= the overall mean,
sm = the effect associated with the mth subject,
m = 1, 2, ..., n
k = the kth treatment effect, k = 1, 2,
ekm = the random error associated with the mth subject who received
treatment k.
where s ~ N(0, σ
) i. i. d. , e ~ N(0, σ
 ) i.i.d. and sm, ekm are independent random 
variables.
Point estimates for the ratios of the geometric means (test/reference) for the primary 
endpoints (see Section 2.1) and their two-sided 90% confidence intervals (CIs) will be 
provided.
For each endpoint, the difference between the expected means for log(T)-log(R) will be 
estimated by the difference in the corresponding adjusted means (Least Squares Means). 
Additionally their two-sided 90% confidence intervals will be calculated based on the 
residual error from the ANOVA and quantiles from the t-distribution. These quantities will 
then be back-transformed to the original scale to provide the point estimate and 90% CIs for 
each endpoint.
Further exploratory analyses
The same statistical model as stated above will be repeated for the primary endpoints but with 
‘subject’ considered as fixed effect.
In addition to the model based approach all parameters will be calculated and analysed 
descriptively.
7.3.2
Secondary endpoint analyses
The secondary endpoints (refer to Section 2.1.3) will be calculated according to the BI SOP 
‘Standards and processes for analyses performed within Clinical Pharmacokinetics/ 
Pharmacodynamics’ (001-MCS-36-472) and will be assessed statistically using the same 
methods as described for the primary endpoints.

7.3.4
Safety analyses
Safety will be analysed based on the assessments described in Section 2.2.2.4. All treated 
subjects (TS, refer to Section 7.2) 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 assigned treatment will be discussed in the minutes of the 
Report Planning Meeting or Decision Log).
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 1.2.4) 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 
previous 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.
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.
7.6
RANDOMISATION
In each trial part, the subjects receive all treatments in the same order, thus no randomisation 
for the treatment assignment is performed (see also Section 4.1.3).
7.7
DETERMINATION OF SAMPLE SIZE
It is planned to enter a total of 14 subjects in each trial part (accounting for up to 2 dropouts 
or non PK evaluable subjects). The planned sample size is not based on a power calculation 
but is considered sufficient to achieve the aims of this exploratory trial. With this sample size, 
the following precision in estimating the ratio of geometric means (test/reference) can be 
expected with 95% probability. Precision is defined as the ratio of upper CI limit to the 
relative BA estimate. Note that the precision is independent of the actual ratio of geometric 
means.
The observed intra-individual coefficient of variation (gCV) for rosuvastatin and for 
dabigatran in previous trials [c08983809-01, c13060859-01, U09-3249-02] were ranging 
from 10% to 30%.
For various assumptions around the gCV, Table 7.7: 1 provides an overview of the 
achievable precision for estimating the ratio of geometric means (test/reference). For 
illustrative purposes, the expected 90% confidence intervals with 95% tolerance probability 
are displayed for different values of the ratios T/R of geometric means.

*Ratio of geometric means (test/reference) for a PK endpoint is defined by exp(T)/exp(R).
The expected 90% confidence interval limits in the table were derived by
CI limit,  = exp(ln(θ) ± ω),
with θ being the ratio (T/R) on original scale and ω the distance from the estimate θ to either 
confidence interval limit on the log-scale, which was obtained from the achievable precision 
on the original scale.
The calculation was performed as described by Julious [R11-5230] using R Version 3.5.1.

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. For drug accountability, refer 
to Section 4.1.8.
ClinBaseTM
In the
Phase I unit – the 
validated ClinBase
system is used for processing information and controlling data 
collected in clinical studies. In addition to its function as a procedure control system, 
ClinBaseTM serves as data base. Instead of being entered into CRFs, selected data are directly 
entered into the system.
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:

meets all inclusion criteria and does not meet any exclusion criteria. The absence of 
records (either medical records, verbal documented feedback of the subject or testing 
conducted specific for a protocol) to support inclusion/exclusion criteria does not 
make the subject eligible for the clinical trial.
Data directly entered into ClinBaseTM (that is, without prior written or electronic record) are 
considered to be source data. The place where data are entered first will be defined in a trial 
specific Source Data Agreement. The data in ClinBaseTM are available for inspection at any 
time.
8.3.2
Direct access to source data and documents
The investigator /institution will allow site trial-related monitoring, audits, IRB / IEC review 
and regulatory inspections. Direct access must be provided to the CRF and all source docu-
ments/data, including progress notes, copies of laboratory and medical test results, which 
must be available at all times for review by the Clinical Research Associate, auditor and 
regulatory inspector (e.g. FDA). They may review all CRFs and informed consents. The 
accuracy of the data will be verified by direct comparison with the source documents descry-
bed in Section 8.3.1. The sponsor will also monitor compliance with the protocol and GCP.
