Trial rationale
BI 1323495 has been characterised to be an inhibitor of P-gp, OATP1B1 and BCRP 
in-vitro. This trial will be performed to test the inhibitory effect of BI 1323495 on 
these drug transporters in-vivo. Dabigatran will be used as model substrate for P-gp, 
rosuvastatin as model substrate for BCRP and OATP1B1.
Trial objectives
To investigate the relative bioavailability of 10 mg rosuvastatin (Part 1) and 150 mg 
dabigatran (Part 2) given alone and together with 
 BI 1323495
Trial design

Duration of treatment
Part 1
Treatment R1: 10 mg rosuvastatin as single dose on study day 1 of period 1 or 2
Treatment T1: 10 mg rosuvastatin + 
g BI 1323495 as single dose on study 
day 1 of period 1 or 2
Drug administrations in period 1 and 2 are separated by a wash-out period of at 
least 7 days.
Part 2
Treatment R2: 75 mg dabigatran as single dose on study day 1 of period 1 or 2
Treatment T2: 75 mg dabigatran + 
 BI 1323495 as single dose on study day 
1 of period 1 or 2
Drug administrations in period 1 and 2 are separated by a wash-out period of at 
least 7 days.
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 sequence, subjects
nested within sequences, period and treatment. CIs will be calculated based on the 
residual error from the ANOVA.
Descriptive statistics will be calculated for all endpoints.

BI 1323495
For a detailed description of the BI 1323495 profile, please refer to the current Investigator’s 
Brochure [c21238478-02].
Clinical experience
At the time of preparing this trial protocol, three Phase I studies with administration of single 
doses of BI 1323495 to healthy male volunteers have been completed, trials 1405-0001 (first-
in-man trial), 1405-0007 (relative BA/food effect), and 1405-0009 (drug interaction with 
itraconazole).
In the single rising dose (SRD) trial 1405-0001, single-dose treatment with up to 600 mg BI 
1323495 or placebo was safe and well tolerated. There was no relationship between the 
occurrence of AEs and dose. Three AEs in subjects receiving BI 1323495 were judged as 
moderate in intensity, all other AEs were classified as mild. No severe or serious AEs were

reported. The most frequently reported treatment-emergent AE was headache, reported for 6 
out of 48 subjects (12.5%) receiving BI 1323495 and 2 out of 15 subjects (13.3%) receiving 
placebo. The next-most frequently reported treatment-emergent AEs were fatigue and 
diarrhea, each reported for 2 out of 48 subjects (4.2%) receiving BI 1323495. In one subject 
receiving 300 mg BI 1323495, a mild (<2-fold ULN) and transient elevation of ALT and 
GLDH was reported.
For further details on safety and tolerability as well as on pharmacokinetics and biomarker 
data of the SRD trial refer to the IB (c21238478-02).

In the food effect trial 1405-0007, a randomised 2-way crossover study to compare the 
relative bioavailability of a single dose of 
 BI 1323495 
administered in 
the fasted state versus fed state (high-fat),
 
Treatment-emergent AEs were reported for 5 out of the 12 treated subjects (41.7%). Adverse 
events were reported for 3 out of 12 subjects (25.0%) in the BI 1323495 fasted treatment 
period and for 2 out of 11 subjects (18.2%) in the BI 1323495 fed treatment period. No 
subjects were reported with AEs in both treatment periods.
Infections and infestations occurred in 2 of the 12 subjects (16.7%): influenza in 1 subject in 
the BI 1323495 fasted treatment period, and otitis externa in 1 subject in the BI 1323495 fed
treatment period. Headache was reported in 2 of the 12 subjects (16.7%), one in each 
treatment period. Mouth injury was reported in 1 of the 12 subjects (8.3%) in the BI 1323495
fasted treatment period. The only investigator-defined drug-related AE was mild headache 
reported for 1 subject [c27223001-01].
Trial 1405-0009, a two-period fixed sequence study in healthy male subjects 
 
 investigated the effects of multiple doses of itraconazole – a 
strong CYP3A4 and P-gp inhibitor - on the relative bioavailability of a single dose of 
 
BI 1323495. The clinical part has been completed and data are currently being evaluated.
Treatment-emergent AEs were reported for 6 out of the 14 treated subjects (42.9%).
Investigator defined drug-related AEs were reported for 3 subjects (21.4%), all of them mild 
or moderate diarrhea under treatment with itraconazole alone or itraconazole + BI 1323495. 
No relevant changes in vital signs, ECG, or laboratory parameters were reported. 
In summary, single doses of BI 1323495 investigated so far in clinical trials with healthy 
subjects were safe and well tolerated.

1.2.2
Rosuvastatin
Rosuvastatin is an HMG-CoA reductase inhibitor indicated for treatment of 
hypercholesterolemia and for prophylaxis of cardiovascular events. Inhibition of HMG-CoA 
decreases hepatic cholesterol production, which, in turn, stimulates hepatocellular uptake of 
low-density lipoproteins. In therapy, the initial rosuvastatin dose is 5-10 mg once daily. The 
daily dose may be increased to up to 40 mg [R19-3033]. 
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 [R19-3033, P14-07833].
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 [R19-3033].
For a more detailed description of the rosuvastatin profile, please refer to the current SmPC 
for Crestor® 10 mg tablets [R19-3033].
1.2.3
Dabigatran
Dabigatran etexilate is a small molecule prodrug which does not exhibit any pharmacological 
activity. After oral administration, dabigatran etexilate is rapidly absorbed and converted to 
dabigatran by esterase-catalysed hydrolysis in plasma and in the liver. Dabigatran is a potent, 
competitive, reversible direct thrombin inhibitor and is the main active principle in plasma.
Since thrombin (serine protease) enables the conversion of fibrinogen into fibrin during the 
coagulation cascade, its inhibition prevents the development of thrombus. Dabigatran inhibits 
free thrombin, fibrin-bound thrombin and thrombin-induced platelet aggregation.
Dabigatran is indicated for primary prevention of venous thromboembolic events in adult 
patients who have undergone elective total hip replacement surgery or total knee replacement 
surgery, and for the prevention of ischaemic stroke in patients with atrial fibrillation. The 
recommended daily dose for primary prevention of venous thromboembolism in orthopaedic 
surgery is 220 mg with an initial dose of 110 mg prior to the surgery. In patients with 
moderately impaired renal clearance (30-50 mL/min) the dose should be reduced to 150 mg 
daily (1 capsule of 75 mg bid) [R18-3151].
The absolute bioavailability of dabigatran following oral administration was approximately 
6.5 %. After oral administration in healthy volunteers, the pharmacokinetic profile of 
dabigatran in plasma is characterized by a rapid increase in plasma concentrations with Cmax
attained within 0.5 and 2.0 hours post administration, a bi-exponential distribution phase and 
a terminal elimination half-life of about 11 hours in healthy elderly subjects. Food does not 
affect the bioavailability of dabigatran etexilate but delays the time to peak plasma 
concentrations by 2 hours. 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 [R18-3151].
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].
For a more detailed description of the dabigatran profile, please refer to the current SmPC for 
Pradaxa® 75 mg hard capsules [R19-3343].
1.2.4
Residual Effect Period
The Residual Effect Period (REP) of BI 1323495, rosuvastatin, and dabigatran, i.e. the period 
after the last dose with measurable drug levels and/or pharmacodynamic effects still likely to 
be present, will be defined as 7 days for each of the 3 products.
1.3
RATIONALE FOR PERFORMING THE TRIAL
Based on in-vitro data BI 1323495 is an inhibitor of P-gp, BCRP, OATP1B1. This trial will 
be performed to test the inhibitory effect of BI 1323495 on these drug transporters in-vivo. 
Rosuvastatin will be used as a model substrate of BCRP and OATP1B1 (trial Part 1) and 
dabigatran as a model substrate of P-gp (Part 2).
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 clinical development of 
BI 1323495. 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, as well as in feeling of lightheadedness or in syncope.
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.
Drug-related risks
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.

In the SRD, food effect, and itraconazole drug interaction trial, single dose administration of 
up to 600 mg BI 1323495 was well tolerated, with no clinically relevant changes in any 
safety laboratory parameter, ECG, and vital signs observed (ref. Section 1.2.1). The 
occurrence of AEs did not appear to be related to BI 1323495 plasma exposure.
As with all drugs, the potential for hypersensitivity and allergic reactions has to be taken into 
consideration when BI 1323495 is administered.
Rosuvastatin
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 trial 352.2100 increased the rosuvastatin exposure from 6.8 to 77 nmol/L (Cmax) 
and from 94 to 321 nmol/L*h (AUC0-∞.). 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 [R18-0241]. Considering this, it is assumed that 
the potential effect of BI 1323495 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 trial 352.2100, no undue risk to healthy subjects is expected from the 
combined administration of 10 mg rosuvastatin and BI 1323495 in this trial.
Dabigatran
In trial 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 daily and of 8 to the dose being used in Part 2 of this trial (75 mg).

Dabigatran etexilate is a sensitive substrate of intestinal 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 given 1 hour before dabigatran intake (2.8 fold increase of
dabigatran Cmax) and with multiple doses of ketoconazole (2.5 fold increase of dabigatran 
Cmax und AUC) [R19-3343]. The observed increase in dabigatran exposure has been well 
tolerated by healthy subjects, which is in line with the described safety margin of 4 at a dose 
of 150 mg, that has not been exceeded by any P-gp inhibitor. 
No undue risk to healthy subjects is expected from the combined administration of 75 mg 
dabigatran etexilate and BI 1323495 in this trial.
Risk mitigation and monitoring

Careful selection of trial population with compound-specific exclusion criteria (see 
Section 3.3.3)

Only healthy subjects will be included in this trial not requiring concomitant 
medications that could – in principle – trigger combined effects on the 
pharmacokinetics and / or safety of the investigational drugs.

Although relevant alterations are not specifically expected, liver function tests 
including total and direct bilirubin, serum creatinine, urea, electrolyte levels, 
glomerular filtration rate, and blood coagulation parameters will be monitored as part 
of the standard safety laboratory assessments (see Section 5.2.3). Subjects with 
impaired liver, kidney or blood coagulation function will be excluded from 
participation in this trial. Furthermore, monitoring will be done for any signs of 
bleeding or bleeding-related adverse events.

Safety surveillance with close monitoring and in-house confinement up to at least 34 
hours after drug administration
Overall assessment
In summary, BI 1323495 has the potential to become an oral treatment for patients with 
COPD or CF. Based upon preclinical and clinical data with BI 1323495 and clinical 
information from competitor compounds 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 drug-
drug-interaction (DDI) trial.
Considering the medical need of the development of an effective treatment to slow the 
progression of COPD for patients with this disease and reduce exacerbations in patients with 
CF, the Sponsor considers that the benefit outweighs the potential risks and justifies exposure 
of healthy male volunteers.

DESCRIPTION OF DESIGN AND TRIAL POPULATION
3.1
OVERALL TRIAL DESIGN AND PLAN
The study comprises two trial parts. Each part follows a randomised, open-label, two-period 
crossover design in healthy male subjects in order to compare the following test and reference 
treatments: 
Treatments in Part 1

Reference (R1): 10 mg rosuvastatin as single dose on study day 1 of period 1 or 2

Test (T1): 10 mg rosuvastatin together with 
 BI 1323495 as single dose on 
study day 1 of period 1 or 2
Treatments in Part 2

Reference (R2): 75 mg dabigatran etexilate as single dose on study day 1 of period 1
or 2

Test (T2): 75 mg dabigatran etexilate together with 
 BI 1323495 as single dose
on study day 1 of period 1 or 2
All treatments will be given after a standardised meal. Drug administrations in period 1 and 2 
will be separated by at least 7 days. For details refer to Section 4.1.
An overview of all relevant trial activities is provided in the Flow Chart for Part 1 and Part 2. 
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).
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 within each of Parts 1 and 2 of the study, 14 healthy male subjects will 
enter. They will be recruited from the volunteers' pool of the trial site.
Only male subjects will be included in the study because no data on reproductive toxicology 
of BI 1323495 are available at this time.

according to CKD-EPI formula), prosthetic heart valves requiring anticoagulant treatment
27. During COVID-19 pandemic: laboratory test indicative of an ongoing SARS-CoV-2 
infection
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. Failure to meet expected enrolment goals
2. New toxicological findings, serious adverse events, or any safety information invalidating
the earlier positive benefit-risk-assessment. More specifically, the trial will be terminated 
or suspended if more than 50% of the subjects have drug-related and clinically relevant 
adverse events of moderate or severe intensity. Furthermore a trial part will terminated or 
suspended, if more than two subjects in the respective trial part have drug-related non-
serious adverse events of severe intensity or if at least 1 drug-related serious adverse 
event is reported.
3. Violation of GCP or the CTP impairing the appropriate conduct of the trial-
4. The sponsor decides to discontinue the further development of the investigational product
3.3.5
Replacement of subjects
Subjects withdrawn due to drug related adverse events will not be replaced. 
Subjects not completing the trial for other reasons (including non PK evaluable subjects) may 
be replaced if considered necessary to reach the aim of the trial. The Clinical Trial Leader 
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 trial subject 
number, and will be assigned to the same treatment as the subject he or she replaces.

4.1.2
Selection of doses in the trial
Rosuvastatin and dabigatran are used in the low range of standard clinical doses.
As regards BI 1323495, a single dose has been chosen that is expected to cover and 
potentially exceed the expected therapeutic exposure to investigate the inhibitory effects in a 
worst-case scenario and to account for potential uncertainties in the prediction of the 
expected therapeutic exposure.
Trial medication will be administered in the fed state, as this is the expected mode of drug 
administration for BI 1323495 in the planned indication of CF where a high proportion of 
patients are on continuous treatment with the CFTR modulator drug ivacaftor that needs to be 
taken together with a fat containing meal.
4.1.3
Method of assigning subjects to treatment groups
Prior to the start of the study, subjects willing to participate will be recruited to the trial parts
according to their temporal availability.
Subjects will be allocated to treatment sequences prior to the first administration of trial 
medication in the morning of Day 1 (Visit 2). For this purpose, numbers of the randomisation 
list will be allocated to the subjects by drawing lots. Subjects are then assigned to a treatment 
sequence according to the randomisation list. Once a subject number has been assigned, it 
cannot be reassigned to any other subject. 
The randomisation list will be provided to the trial site in advance. The randomisation 
procedure is described in Section 7.6.
All subjects of the respective trial 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 part of this trial follows a two period, two-way crossover design. All subjects will 
receive the 2 treatments in randomised order (R-T or T-R). The treatments to be evaluated are 
outlined in Table 4.1.4: 1 below.

The investigator (or authorised designee) will administer the trial medication as an oral dose 
together with about 240 mL of water to subjects who are in a sitting or 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, a standardised normal caloric breakfast (e.g., a roll with cheese, ham, and 
butter) will be served approximately 30 min before drug administration. The subjects must 
completely consume the meal prior to drug intake and consume no other food.
For restrictions with regard to diet, see Section 4.2.2.2.
Subjects will be kept under close medical surveillance until at least 34 h after drug 
administration. During the first 5 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.
PK samples will be labelled in such a way that treatment allocation cannot be derived by the 
analytical site.
4.1.6
Packaging, labelling, and re-supply
BI 1323495
BI 1323495 tablets will be provided by BI. They will be packaged and labelled in accordance 
with local law and the principles of Good Manufacturing Practice. For details of packing and 
the description of the label, refer to the ISF.
The telephone number of the sponsor and the name, address and telephone number of the trial 
site are provided 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. 
No re-supply is planned.
Rosuvastatin and dabigatran etexilate
Rosuvastatin tablets and dabigatran etexilate capsules will be obtained by the clinical trial site 
from a public pharmacy (European commercial goods). The medication will be dispensed out 
of the original, unmodified packages.
4.1.7
Storage conditions
Drug supplies will be kept in their original packaging and in a secure limited access storage 
area in accordance with the recommended (labelled) storage conditions. If necessary, a 
temperature log must be maintained to make certain that the drug supplies are stored at the 
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 contacted immediately.
4.1.8
Drug accountability
The investigator or designee will receive the BI 1323495 investigational drugs delivered from
the sponsor, provided the following requirements are fulfilled:

Approval of the clinical trial protocol by the IRB / ethics committee

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

Only authorised personnel 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.
The investigator or designee 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 medicinal product and trial subjects. The 
investigator or designee will maintain records that document adequately that the subjects 
were provided the doses specified by the CTP and reconcile all investigational medicinal 
products received from the sponsor. At the time of disposal of remaining trial medication, the 
investigator or designee must verify that no remaining supplies are in the investigator’s 
possession.
All unused medication will be disposed of locally by the trial site upon written authorisation 
of the trial clinical monitor. Receipt, usage and disposal of trial medication must be 
documented on the appropriate forms. Account must be given for any discrepancies.
4.2
OTHER TREATMENTS, EMERGENCY  PROCEDURES,
RESTRICTIONS
4.2.1
Other treatments and emergency procedures
There are no special emergency procedures to be followed. No additional treatment is
planned. However, if adverse events require treatment, the investigator can authorise 
symptomatic therapy. In those cases, subjects will be treated as necessary and, if required, 
kept under supervision at the trial site or transferred to a hospital until all results of medical 
evaluations are acceptable.
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.
For Part 1: Drugs which are contraindicated to be co-administered with rosuvastatin (ref. 
R19-3033), as well as acetylsalicylic acid or other drugs that may inhibit platelet aggregation 
or coagulation should be avoided during the entire study.
For Part 2: The intake of analgesics known to inhibit cyclooxygenase (e.g. acetylsalicylic 
acid, ibuprofen and diclofenac) is strongly forbidden starting from 1 week prior to first study
drug administration until last PK-sampling. The same refers to the use of anticoagulants such 
as heparins, heparin ointment, oral anticoagulants (warfarin, rivaroxaban, etc.). Furthermore, 
concomitant systemic administration of strong P-gp inhibitors such as ketoconazole, 
itraconazole, cyclosporine, and dronedarone must be avoided during the entire trial.

4.2.2.2
Restrictions on diet and life style
Grapefruits, Seville oranges (sour or bitter oranges) and their juices, and dietary supplements 
and products containing St. John's wort (Hypericum perforatum) are not permitted from 7 
days before the first administration of trial medication until after the last PK sample of each 
study period is collected.
Alcoholic beverages are not permitted from 24 hours before the first administration of trial 
medication in Period 1 until the end of trial examination after the last PK sample in Period 2 
is collected.
Poppy-seeds containing foods should not be consumed starting 3 days before the first drug 
administration in each treatment period, in order to avoid false-positive results in the drug-
screen.
Consumption of methylxanthine-containing drinks or foods (such as coffee, tea, cola, energy 
drinks, or chocolate) and smoking are not allowed during in-house confinement.
While admitted to the trial site, the subjects will be instructed not to consume any foods or 
drinks other than those provided by the staff. Standardised meals will be served at the times
indicated in the Flow Chart. No food is allowed for at least 5 h after drug intake.
From 1 h before drug intake until lunch, fluid intake is restricted to the water administered 
with the drug, and an additional 240 mL of water at 2 h and 4 h post-dose (mandatory for all 
subjects). From lunch until 24 h post-dose, total fluid intake is restricted to 3000 mL.
Excessive physical activity (such as competitive sport) should be avoided from 7 days before 
the first administration of trial medication until the end of trial examination.
Direct exposure to the sun or exposure to solarium radiation should be avoided during the 
entire study.
4.3
TREATMENT COMPLIANCE
Compliance will be assured by administration of all trial medication in the study centre under 
supervision of the investigating physician or a designee. The measured plasma concentrations 
of trial medication will provide additional confirmation of compliance.
Subjects who are non-compliant (for instance, who do not appear for scheduled visits or 
violate trial restrictions) may be removed from the trial and the CRF will be completed 
accordingly (for further procedures, please see Section 3.3.4.1).

ASSESSMENT OF SAFETY
5.2.1
Physical examination
At screening, the medical examination will include demographics, height and body weight, 
smoking and alcohol history, relevant medical history and concomitant therapy, review of 
inclusion and exclusion criteria, review of vital signs (BP, PR), 12-lead ECG, laboratory 
tests, and a physical examination. At the end of trial examination, it will include review of 
vital signs, 12-lead ECG, laboratory tests, and a physical examination including.
5.2.2
Vital signs
Systolic and diastolic blood pressures (BP) as well as pulse rate (PR) or heart rate (heart rate 
is considered to be equal to pulse rate) will be measured by a blood pressure monitor 
(Dinamap Pro 100, 
) at the times indicated in the 
Flow Chart, after subjects have rested for at least 5 min in a supine position. All recordings 
should be made using the same type of blood pressure recording instrument on the same arm, 
if possible.
5.2.3

) will be performed prior to each 
treatment period, and may be repeated at any time during the study at the discretion of an 
investigator or designee. The results will not be included in the CTR.
The laboratory tests listed in Tables 5.2.3: 1 and 5.2.3: 2 will be performed at

drug screening tests. These tests will be performed at the trial site using AccuSign® DOA 10 
test or comparable test systems.
Laboratory data will be transmitted electronically from the laboratory to the trial site.

Electrocardiogram
Twelve-lead ECGs (I, II, III, aVR, aVL, aVF, V1 - V6) will be recorded using a 
computerised electrocardiograph (CardioSoft EKG System, 
 
) at the times provided in the Flow Chart.
To achieve a stable heart rate at rest and to assure high quality recordings, the site personnel 
will be instructed to assure a relaxed and quiet environment, so that all subjects are at 
complete rest. All ECGs will be recorded for a 10 sec duration after subjects have rested for 
at least 5 min in a supine position. ECG assessment will always precede all other study 
procedures scheduled for the same time to avoid compromising ECG quality. 
All ECGs will be stored electronically on the Muse CV Cardiology System (
 
). Electrode placement will be performed according to the 
method

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 
encephalopathy, unexplained coagulopathy, right upper quadrant abdominal pain, 
etc.) without lab results (ALT, AST, total bilirubin) available, the Investigator should

make sure that these parameters are analysed, if necessary in an unscheduled blood 
test. Should the results meet the criteria of hepatic injury alert, the procedures 
described in the DILI checklist should be followed.
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)

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 immediately (within 24 hours) to the sponsor’s 
unique entry point (country specific reporting process 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 send 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.

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 BI 1323495, rosuvastatin and 
dabigatran
For quantification of rosuvastatin (Part 1), dabigatran (Part 2), and BI 1323495
concentrations in plasma, 2.7 mL of blood will be drawn for each analyte 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 per analyte will be 
obtained 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 within 90 min, with interim storage of blood samples on ice-bath or 
refrigerated. 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. The second aliquot will be transferred to the 
analytical laboratory after the bioanalyst has acknowledged safe arrival of the first aliquot. 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.

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 measurements outlined in Section 5.3 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, the end of trial examination, and measurements and 
assessments scheduled to occur ‘before’ trial medication administrations are provided in the 
Flow Chart.
If not stated otherwise in the Flow Chart, the acceptable deviation from the scheduled time 
for the assessment of safety (e.g. vital signs, ECG, laboratory tests) will be ± 60 min.
If scheduled in the Flow Chart at the same time as a meal, blood sampling, vital signs, and 
12-lead ECG recordings have to be done first. Furthermore, if several measurements 
including venepuncture are scheduled for the same time, venepuncture should be the last of 
the measurements due to its inconvenience to the subject and possible influence on 
physiological parameters.
For planned blood sampling times, refer to the Flow Chart. While these nominal times should 
be adhered to as closely as possible, the actual sampling times will be recorded and used for 
the determination of pharmacokinetic parameters.
If a subject misses an appointment, it will be rescheduled if possible. The relevance of 
measurements outside the permitted time windows will be assessed no later than at the Report 
Planning Meeting.
6.2
DETAILS OF TRIAL PROCEDURES AT SELECTED VISITS
6.2.1
Screening period
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.
6.2.2
Treatment periods
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 34 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, assessments will be done in an ambulatory fashion.
For details on time points and procedures for collection of plasma samples for PK and 
biomarker analysis, refer to Flow Chart, Section 5.3.2 and 5.4.

The safety measurements performed during the treatment periods are specified in Section 5.2
of this protocol and in the Flow Chart. For details on times of all other trial procedures, refer 
to the Flow Chart. AEs and concomitant therapy will be assessed continuously from 
screening until the end of trial examination.
6.2.3
Follow-up period and trial completion
For AE assessment, laboratory tests, recording of ECG and vital signs, and physical 
examination during the follow-up period, see Section 5.2.
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 10 mg 
rosuvastatin (Part 1) and 75 mg dabigatran (Part 2) in plasma when given as oral single dose
together with a single dose of 
 BI 1323495 (Test, T1 and T2) as compared to when 
given alone as oral single dose (Reference, R1 and R2) on the basis of the primary and 
secondary pharmacokinetic endpoints, as listed in Section 2.1.2 and 2.1.3. Each trial part will 
be conducted as a two-treatment, two-period, randomised cross-over design, which allows 
intra-subject comparisons. It will be evaluated statistically by use of a linear model for 
logarithmically transformed PK endpoints.
The assessment of safety is a further objective of this trial, and will be evaluated by 
descriptive statistics for the parameters specified in Section 2.2.2.2.
7.2
NULL AND ALTERNATIVE HYPOTHESES
The relative bioavailability of rosuvastatin (Part 1) / dabigatran (Part 2) given alone 
compared with a combined administration with BI 1323495 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 randomized and
treated with at least one dose of study drug. The treated set will be used for safety 
analyses.
Pharmacokinetic parameter 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/she 
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, and 
BI 1323495 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 in the respective treatment 
period

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 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: 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. The model is described by the 
following equation:

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 
all sources of variation (‘sequence’, ‘subjects within sequences’, ‘period’, ‘treatment’) 
considered as fixed effects.
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 randomised treatment will be discussed in the minutes of the 
Report Planning Meeting).
Treatments will be compared in a descriptive way. Tabulations of frequencies/proportions 
will be used to evaluate categorical (qualitative) data, and tabulations of descriptive statistics 
will be used to analyse continuous (quantitative) data.
Measurements (such as ECG, vital signs, or laboratory parameters) or AEs will be assigned to 
treatments (see Section 4.1) based on the actual treatment at the planned time of the 
measurement or on the recorded time of AE onset (concept of treatment emergent AEs).
Therefore, measurements planned or AEs recorded prior to first intake of trial medication will 
be assigned to the screening period, those between first trial medication intake and end of 
REP (see Section 1.2.4) 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
For each trial part, subjects will be randomised to one of the 2 treatment sequences in a 1:1 
ratio. The block size will be documented in the CTR.
The sponsor will arrange for the randomisation as well as packaging and labelling of trial 
medication. The randomisation list will be generated using a validated system that uses a 
pseudo-random number generator and a supplied seed number so that the resulting allocation 
is both reproducible and non-predictable.
The randomisation list will contain additional blocks to allow for subject replacement (refer 
to Section 3.3.5).
7.7
DETERMINATION OF SAMPLE SIZE
It is planned to enter 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 ranged from 
from 9.0 to 19.7% for AUC and from 14.1 to 28.4% for Cmax, whereas the observed intra-
individual coefficient of variation (gCV) for dabigatran were ~20% for Cmax as well as for 
AUC in previous trials [c08983809-01, c13060859-01, U09-3249-02].
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.

The consent and re-consenting process should be properly documented in the source 
documentation.
For subjects enrolled during the COVID-19 crisis: In addition to the study specific informed 
consent, separate written consent will be obtained for testing on SARS-CoV-2 infection.
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:

Subject identification: sex, year of birth (in accordance with local laws and 
regulations)

Subject participation in the trial (substance, trial number, subject number, date subject 
was informed)

Dates of subject’s visits, including dispensing of trial medication

Medical history (including trial indication and concomitant diseases, if applicable)

Medication history

AEs and outcome events (onset date [mandatory], and end date [if available])

SAEs (onset date [mandatory], and end date [if available])

Concomitant therapy (start date, changes)

Originals or copies of laboratory results and other imaging or testing results, with 
proper documented medical evaluation (in validated electronic format, if available)

ECG results (original or copies of printouts)

Completion of subject’s participation in the trial (end date; in case of premature 
discontinuation, document the reason for it, if known)

Prior to allocation of a subject to a treatment into a clinical trial, there must be 
documented evidence in the source data (e.g. medical records) that the trial participant 
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 
documents/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 
described in section 8.3.1. The sponsor will also monitor compliance with the protocol and 
GCP.
