Protocol Summary
1.1
Synopsis
Protocol Title:           Multicenter, randomized, placebo controlled, double-blind, parallel 
group, dose-finding Phase 2 study to evaluate the efficacy and safety of 
BAY 2433334 in patients following an acute myocardial infarction.
Short Title:
PACIFIC-AMI - Phase 2 Program of AntiCoagulation via Inhibition 
of FXIa by the oral Compound BAY 2433334 – Acute Myocardial
Infarction study
Rationale:
This study will explore a dose range of BAY 2433334 in order to 
determine the dose that is efficacious and safe and that can be used in a 
Phase 3 study in the same indication. Rivaroxaban in addition to single 
or dual antiplatelet therapy (acetylsalicylic acid +/- clopidogrel) is the 
only non-Vitamin K oral anticoagulants (NOAC) approved for 
secondary prevention of acute coronary syndrome (ACS) in Europe. In 
addition, the COMPASS study has also shown the benefit of this 
combination (rivaroxaban in addition to acetylsalicylic acid) in patients 
with stable coronary artery disease (CAD)/peripheral artery disease 
(PAD). The clinical use of antiplatelet therapies together with an 
anticoagulant in acute coronary syndrome is limited due to concerns 
about bleeding risk. The inhibition of FXIa on top of antiplatelet 
therapy is expected to not lead to a relevant increase in bleeding and 
especially major bleeding, while maintaining the efficacy benefit 
shown for the combination of antiplatelet therapies and rivaroxaban.

Objectives
Endpoints
Primary

to evaluate whether the oral FXIa 
inhibitor BAY 2433334 compared to 
placebo leads to a lower incidence of 
cardiovascular (CV) death, MI, stroke 
and stent thrombosis in participants with
an acute myocardial infarction and who 
are treated with dual antiplatelet therapy
Primary Efficacy Endpoint

the composite of CV death, MI, stroke
and stent thrombosis 
Secondary Efficacy Endpoints

all cause mortality

CV death

MI

stroke

stent thrombosis

to evaluate whether the incidence of 
bleeding is similar for BAY 2433334 
compared to placebo in participants 
with an acute myocardial infarction and 
who are treated with dual antiplatelet 
therapy
Primary Safety Endpoint

Bleeding Academic Research 
Consortium (BARC) definition type 2, 3 
and 5 
Secondary Safety Endpoints

all bleeding

BARC bleeding definition type 3, 5

BARC bleeding definition type 1, 2, 3, 5
The primary efficacy estimand is the hazard ratio of the composite of CV death, MI, stroke  
and stent thrombosis comparing BAY 2433334 (20 and 50 mg pooled) with placebo in adult 
participants with an AMI treated with DAPT while alive and regardless of treatment 
discontinuation.
The secondary efficacy estimands are defined following the same approach for the 
individual secondary endpoints as done for the primary efficacy estimand.
The primary safety estimand is the hazard ratio of BARC type 2, 3 and 5 bleeding 
comparing pooled BAY 2433334 with placebo in adult participants with an AMI treated 
with DAPT and who have taken at least one dose of study medication of BAY 2433334 or 
placebo and while the patient is alive and exposed to study drug
The secondary safety estimands are defined following the same approach for the individual 
secondary endpoints as done for the primary safety estimand.

Overall Design:
Study 20603 is a multicenter, randomized, placebo controlled, double-blind, parallel group, 
dose-finding study. 
The study population includes participants following an AMI with a plan for treatment with 
DAPT (acetylsalicylic acid + P2Y12 inhibitor) after discharge from hospital. 
Participants will be screened and have to be randomized within 5 days of hospitalization for 
the index AMI event.
Stratification will be based on the intended P2Y12 inhibitor use (ticagrelor/prasugrel versus 
clopidogrel) after hospital discharge. 
Participants should have the initial coronary angiography and revascularization procedures, 
either percutaneous coronary intervention (PCI) or coronary artery bypass grafting (CABG),
as treatment for the index AMI event performed before randomization. However, a planned,
staged PCI procedure can be performed after randomization. 
If all information is available, participants can be randomized on the day of screening.
Disclosure Statement: This is a parallel-group study with 4 arms that is participant and 
investigator blinded
Intervention Model: Parallel
Primary Purpose: Treatment
Number of Arms: 4 arms (3 investigational drug arms and 1 placebo arm)
Number of Participants:
Approximately 1650 participants will be screened to achieve 1600 randomly assigned to study 
intervention for an estimated total of 400 evaluable participants per intervention group. More 
details are available in Section 9.2 Sample Size Determination.
Intervention Groups and Duration:
BAY 2433334 is the sponsor’s study intervention under investigation. Placebo is used as 
comparator. Study intervention duration and dose regimen are tabulated as follows:

** Screening and randomization must occur during hospitalization and latest within 5 days of hospital admission. Intake of the first dose of study 
drug will start as soon as possible and on the same day as randomization (day 1).
a if screening and randomization are performed on the same day, this procedure does not need to be repeated.
b at each contact, participants should be reminded regarding study drug compliance.
c Participants will perform their safety follow-up phone call 2 weeks after the EoT visit or the ET visit whichever occurs earlier. (i.e. in case of Early 
Termination 2 weeks after last study drug intake).
d ECG machine that automatically calculates the heart rate and measures PR, QRS, QT and QTc intervals should be used.
e Creatinine and eGFR results as well as AST and ALT values measured in the local laboratory for screening. Current laboratory results available 
for the index hospitalization for the myocardial infarction can be used. Full safety labs done at randomization (Central Lab).
f The visit can be performed at a later time point if participant on inpatient rehabilitation facility and this visit cannot be arranged.
g  Refer to Table 1–1: PK, PD and Biomarker sampling
h  Outcome events including all bleeding, death, MI, stroke and stent thrombosis as well as events indicative of a potential outcome (see Section 
10.1.5.4) need to be reported on  dedicated forms in the eCRF on an ongoing basis, even if the participant is permanently discontinued from 
the study treatment.
i at visits 3, 5, 7, 9 and 11: any new concomitant medication and AEs or outcome events will be captured during the telephone calls.

a At Visit 4: in order to collect pre-dose samples for PK and PD, participants should take their study 
drug at the site only after blood sampling. The investigator must record the time when the study drug
is taken at the site. A phone call before V4 to remind participants is recommended.
b  The minimum time between the 2-4 h post-dose and the 4-12 h post-dose samples, if collected the 
same day, should be at least 1 hour.
c  The late sample 4-12 hr post-dose sample can be taken at week 4 (visit 4) or at a later-on visit (e.g.
Visit 6). The exact time of when the study drug was administered must be recorded as well as PK 
and PD post-dose sample collection time.
d At Visit 8 (week 26) participants should take their study drug at the site, in order to collect pre-dose 
samples for PK/PD and biomarkers. However, in case Visit 8 is also the EOT visit as well as in case 
of ET visit, no study drug will be administered.
e If study drug is temporily stopped, PK/PD blood samples should only be obtained if study drug has
been restarted and sustained for  at least 4 days, see Section 7.1.1
The exact times of PK, PD and biomarker sampling need to be recorded as well as the time of the 
most recent / associated study drug intake (i.e. on the PK/PD sampling day, as well as the previous

Introduction
BAY 2433334 is a direct, potent inhibitor of activated coagulation factor XI (FXIa) being 
developed for three main indications:
1.
Prevention of stroke and systemic embolism in patients with AF (cardioembolic stroke 
prevention) 
2.
Secondary stroke prevention in patients after an ischemic stroke (large artery, lacunar 
stroke, or embolic stroke of undetermined source [ESUS]) (non-cardioembolic stroke 
prevention)
3.
Prevention of major adverse cardiac events (CV death, MI, stroke) in patients after an
acute myocardial infarction (AMI).

Study 20603 will be a  Phase 2 study with a 6 to 12 months treatment duration and will test 
BAY 2433334 against placebo in patients following an AMI who are treated with dual 
antiplatelet therapy. 
The current clinical development of BAY 2433334 includes two additional Phase 2 studies in 
patients with AF (study 19765, 3 months treatment duration, apixaban as comparator) and in 
patients with non-cardioembolic ischemic stroke (study 19766, 6-12 months treatment 
duration, on top of primarily single antiplatelet therapy, placebo as comparator). 
Each individual study will have its own objectives. However, in order to reach and draw 
conclusions concerning safety in general, and especially bleeding, the program is designed to 
pool the data across the three Phase 2 studies to help further characterize safety and efficacy.
2.1
Study Rationale
This Phase 2 study will explore a dose range of BAY 2433334 in order to determine the dose 
that is efficacious and safe and that can be used in a Phase 3 trial in the same indication.
The benefit of the concept of adding anticoagulation to antiplatelet treatments has been 
proven by rivaroxaban for ACS in the ATLAS TIMI 51 trial (rivaroxaban in addition to single 
or dual antiplatelet therapy consisting of acetylsalicylic acid [ASA] +/- clopidogrel), and for
patients with stable CAD/PAD in the COMPASS trial (rivaroxaban in addition to ASA).
However, its clinical use in ACS is limited, as patients and healthcare providers are concerned 
about the bleeding risk for triple therapy including 2 antiplatelet therapies (ASA + P2Y12
inhibitors) and an anticoagulant. 
The use of BAY 2433334, as an oral FXIa inhibitor, could address this concern, as it is 
expected not to lead to a relevant increase in bleeding and especially major bleeding, while 
maintaining the efficacy benefit of a combination of antiplatelet therapies and an 
anticoagulant. This is based on the available preclinical data, data from patients with inherited 
FXI deficiency and first clinical data from two Phase 2 proof-of-concept studies in patients 
undergoing total knee replacement (please see Section 2.3).
BAY 2433334 as an inhibitor of FXIa is therefore an attractive candidate to evaluate as a 
potential add-on to dual antiplatelet therapy in patients after an acute myocardial infarction.
2.2
Background
2.2.1
Disease Background
CV disease is the most common cause of mortality worldwide, and the majority of CV 
mortality is attributable to coronary heart disease (CHD). The incidence and prevalence rates 
of CHD remain high throughout the developed world. In the United States (US), the 
American Heart Association (AHA) reported that the prevalence of CHD in adults ≥20 years 
of age is 7.0%. Acute myocardial infarction is a subcategory of CHD and typically leads to an 
acute onset of chest pain or discomfort. The majority of myocardial infarctions arise from an 
acute rupture of an atherosclerotic plaque that leads to a complete blockage of the blood flow 
in a coronary artery and consequently damage of the heart.

According to a current report of the American Heart Association, the prevalence of MI is 
3.1% of US adults (7.9 Million US Americans), and the annual incidence rate of MI in the US 
is 935,000. Within one year after MI, 19% of men and 26% of women aged 45 years and 
older will die. 
2.2.2
Treatment Guidelines
Following an acute myocardial infarction, patients remain in a persistent hypercoagulable  
state and are at risk for adverse thromboembolic events. European Society of Cardiology 
(ESC)/European Association for Cardio-Thoracic Surgery (EACTS) guidelines (Valgimigli et 
al. 2018) recommend that in patients with ACS, regardless of initial treatment strategy,  
DAPT with a P2Y12 inhibitor combined with ASA is recommended  for 12 months unless 
there are contraindications such as excessive risk for bleeding.
Similar guidelines are available from the ACC/AHA. The AHA guidelines (AHA/ACC 2014)
also recommend 12 months of DAPT for patients without significant bleeding risks.  Both 
guidelines suggest that the duration of DAPT be adjusted to the individual patient’s risk of 
recurrent ACS vs. risk of bleeding.
2.2.3
FXIa Inhibitor: Mode of Action
BAY 2433334 is a direct, potent inhibitor of activated coagulation factor XI (FXIa). 
The plasma serine protease zymogen factor XI (FXI) is activated after initiation of the contact 
activation pathway via factor XIIa (FXIIa) and during the amplification phase as part of a 
positive feedback loop through activation by thrombin. FXIa is thought to contribute strongly 
to clot progression, which may potentially lead to vessel occlusion and pathological 
manifestations of thrombosis, but has minor impact on hemostasis due to its limited role in the 
initiation phase of the extrinsic pathway. 
FXIa inhibition by BAY 2433334 may offer the opportunity to prevent thrombosis without 
interference with primary hemostasis and to thereby set a paradigm shift compared to Vitamin 
K antagonists and Non-Vitamin K oral anticoagulants (NOACs).

2.2.4.1
Preclinical / Toxicology Data
Preclinical data using FXI-deficient mice or studies using pharmacological inhibition of FXIa 
in different animal models, for example a FeCl-induced thrombosis model, showed a benefit 
in reduced thrombus formation. The data indicate that higher efficacy might be possible to 
achieve when compared to the therapeutic doses of NOACs. 
The benefit in these animal models was combined without an associated increase in bleeding 
time as is seen for NOACs in these models. Importantly, no further increase in bleeding time 
was seen even when BAY 2433334 was given on top of dual antiplatelet therapy.
Data regarding toxicology studies as well as more preclinical data can be found in the 
Investigator`s Brochure but are also partly described in the benefit/risk section (see Section 
2.3).
2.2.4.2
Clinical Data
So far, 156 healthy male subjects have received treatment with BAY 2433334 in doses 
ranging from 5 mg to 150 mg after single dosing and up to 100 mg once daily in multiple 
dose settings. 
Safety
The single dose escalation study (study 19372) with BAY 2433334 is clinically complete. 
Single doses of 5 mg to 150 mg have been investigated, as well as a food effect study part 
with 25 mg. No clinically relevant signs or symptoms of bleeding were observed.
The multiple dose escalation study (study 19665) has also been clinically completed and 
evaluation is still ongoing. Therefore, the results are preliminary. It consisted of three parts: 
Part A, wherein 25 mg, 50 mg and 100 mg BAY 2433334 were given once daily over 9 
consecutive days, part B, where 25 mg were given twice daily, and part C, where a 
midazolam interaction was investigated with 25 mg and 75 mg BAY 2433334.
Overall, BAY 2433334 was safe and well tolerated. More details on safety can be found in the 
Investigator`s Brochure.   
Pharmacodynamics 
The following pharmacodynamic parameters were investigated in both the FiM study (study 
19372) and MDE study (study 19665): aPTT, FXI activity (AXIA assay), and FXI 
concentration. Bleeding time was investigated after single dose administration only (study 
19372)
A dose dependent prolongation of aPTT was observed after single dosing with a close direct 
correlation between aPTT and plasma concentration:

In the 25 mg OD dose step of the multiple dose (MD) study 19665 a prolongation of 
aPTT of 
 (mean, compared to baseline) after single dosing and 
 (mean) at 
steady state was seen.


In the 50 mg OD dose step of the MD study 19665 a prolongation of aPTT of

 (mean) at steady state 
was seen. 

In the 100 mg OD dose step of the MD study 19665 a prolongation of aPTT of 
 
(mean, compared to baseline) after single dosing and 
 (mean) at steady state 
was seen. 
FXI activity (AXIA assay) is inhibited by a mean of ~85% after 25 mg SD and a mean of 
~95% (25 mg OD) at steady state. After 50 mg and 100 mg SD and MD, activated FXI 
activity is inhibited by a mean of >95% both after first dose and at steady state. The duration 
of the inhibition of FXI activity (AXIA assay) is dose dependent. Complete inhibition was 
reported for 12 hours for 50 mg at steady state and this is prolonged up to 24 hours for 100 
mg at steady state. 
Pharmacodynamic parameters aPTT and FXI activity correlated well with observed plasma 
concentrations of BAY 2433334.
No relevant changes of FXI concentration or PT were observed in either study. 
No clinically relevant changes in bleeding time were observed after single dose application. 
Pharmacokinetics
The key pharmacokinetics features of BAY 2433334 based on current available data and 
when administered as IR tablets can be summarized as follows. 

BAY 2433334 is absorbed with a median time to reach maximum plasma concentration 
(tmax) of 2 to 4 hours (fasted state).

There is no hint for any deviation from dose-proportionality found for doses between 
5 mg and 150 mg.

Relative bioavailability of BAY 2433334 administered as IR tablet amounted to 
approximately 89.5% with regard to AUC and of 86.0% with regard to Cmax compared to 
administration as an oral solution.

A high-fat, high-calorie meal has minor effect on the AUC of 25 mg BAY 2433334 
(decrease of 12.4%) and results in a reduced absorption rate (31.4% decrease in maximum 
plasma concentration [Cmax] and 2.5 h prolongation in tmax).

The variability was low to moderate for AUC and Cmax (%geoCV approx. 15 to 30%).

The degree of accumulation of BAY 2433334 is low regarding Cmax,md or AUCτ,md after 
once daily multiple dosing with RACmax between 1.4 and 1.6 and RAAUC between 1.5 and 
1.7.

Pharmacokinetics were linear over time.

The metabolite M-10 (BAY 2826102, formed by amide hydrolysis of the central amide 
and subsequent N-acetylation) is expected to be a main compound in human plasma with a 
metabolic ratio to parent drug of approx. 24 to 30%. This metabolite is not 
pharmacologically active.


Terminal half-life is 14.0 to 17.4 hours supporting once daily dosing.

Low apparent oral plasma clearance (CL/F) of about 3.19–4.27 L/h was observed in 
geometric mean (corresponding to a blood clearance/F of 4.54-6.07 L/h).

Based on preliminary evaluation of the 50 mg dose step in the multiple dose escalation 
study (study 19665) renal elimination was low (15%).  

Based on the preliminary ethnic evaluation up to the 50 mg dose step of single and 
multiple dose in Caucasians (study 19665) and Japanese (study 19667), there is no large 
difference in PK between races though geometric mean of AUC and Cmax in Japanese 
were slightly higher than in Caucasians. 

Based on preliminary evaluation the strong CYP3A4 inhibitor itraconazole increased 
BAY 2433334 exposure by 100% (2-fold) while maximum plasma concentrations were 
not changed (study 19664). Terminal half-life was prolonged from 16 to 29 hours.

2.3
Benefit/Risk Assessment
The FXIa inhibitor BAY 2433334 is an oral anticoagulant, that is planned to be developed for 
patients with atrial fibrillation, acute myocardial infarction as well as non-cardioembolic 
ischemic stroke. This Phase 2 study will be the first study investigating BAY 2433334 in 
patients after an acute myocardial infarction. Once daily doses of 10 mg, 20 mg and 50 mg 
will be tested in the study.  
BAY 2433334 as a FXIa inhibitor is expected to have a lower risk for clinically significant 
bleeding when compared to other oral anticoagulants (VKAs and NOACs) is not expected to 
increase the risk for clinically significant bleeding, while leading to an efficacy benefit.
The expected clinical profile of BAY 2433334 is based on preclinical data as well as clinical 
data from FXI-deficient individuals and other FXI-targeting compounds. The separation of 
bleeding and efficacy might be explained by the fact that inhibition of FXIa affects the 
intrinsic and propagation pathways but keeps the extrinsic pathway unaffected, that is
activated in case of vessel injury. 
At this stage of development there is no clinical evidence available yet to confirm the efficacy 
benefit of BAY 2433334. However, the data supporting that this compound is expected to 
lead to prevention of thrombosis events in the intended indications are the following: 

FXI-deficient knockout mice are protected from thrombosis. In addition, in various 
thrombosis models in rabbits, BAY 2433334 demonstrated reduced thrombus weight, 
and this was seen when given with or without antiplatelets. While therapeutic doses of 
NOACs lead to a 20-30% reduction in thrombus formation in the same animal models, 
BAY 2433334 was able to reduce the thrombus formation by up to ~ 90%.

In people with inherited Factor XI deficiency, a rare coagulation deficiency caused by 
either reduced production of factor XI or by production of a loss-of-function factor XI 
molecule, a lower risk for venous thromboembolic events as well as cardiovascular 
events and especially stroke has been reported.


Increased levels of FXI are reported as a risk factor for venous thromboembolism and 
myocardial ischemia or stroke. Whether there is a causal relationship is unclear.

A first proof of concept targeting FXI as anticoagulant has been shown by a FXI 
Antisense Oligonucleotide. Reducing FXI levels in patients undergoing total knee 
arthroplasty (TKA) led to an improved prevention of postoperative venous 
thromboembolism (VTE), when compared to enoxaparin. Based on modeling 
approaches, the inhibition levels of FXIa activity in the study can be achieved with the 
20 mg and 50 mg doses of BAY 2433334 (see also the Investigator’s Brochure).

Phase 1 studies in healthy volunteers are not able to assess efficacy. However, after 
multiple dosing the highest planned dose of 50 mg to be tested in Phase 2 lead to
complete of inhibition during 12 hours of the day. This was combined with a mean 
prolongation of aPTT of 
. 
At this stage of development, the safety profile has not been established. The following 
information related to safety as well as potential risks for patients is available:
1.
Bleeding is the main safety concern related to antithrombotic therapies. For an inhibitor 
of FXIa a lower bleeding risk is expected. Data supporting this are listed below:
o
FXI-deficient knockout mice do not show as bleeding phenotype. In addition, 
in the thrombosis animal models no increase in bleeding time (gum and ear) 
was reported. Importantly, no further increase in bleeding time was seen when 
BAY 2433334 was given on top of dual antiplatelet. In addition, in the 
toxicology studies no relevant bleeding was reported for up to 37-fold the 
expected human exposure of the planned 50 mg multiple dose in patients.
o
Patients with inherited FXI deficiency are typically identified when presenting 
with a prolonged activated partial thromboplastin time (aPTT) in routine 
clinical testing. There is no direct association between FXI activity levels and 
bleeding risk, though historically and predominantly in the Ashkenazi Jewish 
population, FXI deficiency has been categorized as having a mild bleeding 
phenotype that generally only manifests following injury or trauma in tissues 
with high fibrinolytic activity.
o
In the completed and ongoing Phase 1 studies conducted with BAY 2433334, 
no relevant bleeding events were reported so far.
A risk for bleeding cannot be excluded in patients after an acute myocardial infarction 
included in the Phase 2 study especially as patients will be treated on top of dual 
antiplatelet therapy. Therefore, bleeding will be closely monitored in the study and will 
be adjudicated by an independent clinical event committee.
2.
In toxicology studies, the liver was identified as a  target organ in the rat but not in the 
dog. This included dose-dependent spontaneous, mostly transient increases in liver 
enzymes in single animals without clear correlation to histopathological findings in the 
livers. Based on this, patients with a >2.5 ALT or AST increase will be excluded from 
the study and liver findings during the study are defined as AE of special interest in the 
study.

3.
Single doses of BAY 2433334 up to 150 mg and multiple doses up to 100 mg once 
daily for 9 days have been safe and well tolerated. This included general safety, 
laboratory, vital signs and ECGs. The doses were 2 and 3-fold higher than planned in 
this Phase 2 study.
4. Based on preliminary evaluation the strong CYP3A4 inhibitor itraconazole increased 
BAY 2433334 exposure by 100% (2-fold) while maximum plasma concentrations were 
not changed (study 19664). Terminal half-life was prolonged from 16 to 29 hours. 
Therefore, strong CYP3A4 inhibitors and inducers should not be taken concomitantly 
with BAY 2433334 in this study until further information is available.
In order to ensure the safety of the participants during the study conduct an independent data 
monitoring committee (IDMC) will monitor the safety of all participants enrolled in all 3 
Phase 2 studies with a focus on bleeding and general safety. In addition, a focus of the IDMC 
review will be on any stroke occurring during the study.
Several Factor XI (FXI) and activated Factor XI (FXIa) inhibitor assets are currently in 
development as antithrombotics, including antisense oligonucleotides (ASOs), antibodies and 
small molecules (SMOLs).
In summary, in this Phase 2 study patients after an acute myocardial infarction will receive for 
the first time BAY 2433334. Study drug will be given  on top of their usual therapy with dual 
antiplatelet therapy. The main objective of the study is to evaluate whether the addition of 
BAY 2433334 will lead to no relevant increase in bleeding when given on top of dual 
antiplatelet therapy and that this is combined with a treatment benefit in terms of reduction of 
CV death, MI, stroke and stent thrombosis.  An additional objective is to guide dose selection 
for Phase 3. Currently, available preclinical and clinical data from the ongoing study 
regarding the key risks do not indicate an unfavorable risk profile for BAY 2433334. The 
overall risk is anticipated to be acceptable in the context of the drug benefit.
More detailed information about the known and expected benefits and risks and reasonably 
expected adverse events of BAY 2433334 may be found in the Investigator’s Brochure.

Study Design
4.1
Overall Design
Study 20603 is a multicenter, randomized, placebo controlled, double-blind, parallel group, 
dose-finding phase 2 study. Figure 1–1 displays the overall study design.
Approximately 1600 participants (400 per arm) from approximately 150 study centers 
worldwide will be randomized 1:1:1:1 to one of the three investigational drug arms (BAY 
2433334) or to the placebo arm, in addition to their SoC dual antiplatelet background therapy
(for details see Section 6.5).
Stratification will be based on the intended P2Y12 inhibitor use (ticagrelor/prasugrel versus 
clopidogrel) after hospital discharge. 
The number of participants with STEMI enrolled in the study will be limited to no more than 
50% of all participants.
The maximum duration of study participation is planned to be approximately 55 weeks, 
consisting of:

Screening Period  (Visit 1 until Visit 2) : ≤ 5 days 
Participants will be screened and have to be randomized during hospitalization for the 
index AMI event and latest within 5 days of hospital admission. Participants should
have the initial coronary angiography and revascularization procedures, either 
percutaneous coronary intervention (PCI) or coronary artery bypass grafting (CABG), 
as treatment for the index AMI event performed before randomization. However, a 
planned, staged PCI procedure can be performed after randomization.  
If all information is available, participants can be randomized on the day of screening.

Treatment Period ( from Visit 2 through Visit 12): Minimum 26 weeks and 52 
weeks maximum 
The duration of the planned double-blind interventional treatment for each participant 
will be 26 to 52 weeks.

The planned double-blind treatment phase starts at randomization and ends at week 52 
or the study treatment end date. Participants active on treatment at the time the last 
participant is randomized in the study, the maximum treatment duration beyond this 
date will be no longer than an additional 26 weeks. Thus, participants will have a total 
treatment duration of a minimum 26 weeks to a maximum of 52 weeks.

Safety Follow-up Period ( Visit 13): 14 days (+ 7 days) after EoT or ET
Study visits will take place as visits at the study sites  and telephone calls. Visits at the study 
sites take place at screening and randomization (Visit 1 and Visit 2), at Week 4 (Visit 4), 
Week 13 (Visit 6), Week 26 (Visit 8), Week 39 (Visit 10) and at Week 52 / EoT ( Visit 12). 
Telephone calls take place at Week 2 (Visit 3), Week 8 (Visit 5), Week 20 (Visit 7), Week 32 
(Visit 9) and at Week 46 (Visit 11), as well as 2 weeks after the end of treatment visit (i.e.
safety follow-up, Visit 13).
For participants who prematurely discontinue from the study drug, an ET visit (Visit 12a) 
should take place as soon as possible as on-site visit. Participants are asked to continue the 
study schedule of visits until completing all the study visits or end of study is declared. 
Telephone calls take place 14 days after ET visit (i.e. Safety follow-up, Visit 13). Further 
details are reported in Section 7.1.
Details of study procedures and their timing are summarized in the SoA (Section 1.3).
4.2
Scientific Rationale for Study Design
This Phase 2 dose finding study in patients after an AMI will test three doses of BAY 
2433334 against placebo. This will allow to test different degrees of FXIa inhibition and 
determine the dose to be tested in Phase 3.
Study 20603 is a multicenter,randomized, placebo controlled, double-blind, parallel group, 
dose-finding Phase 2 study in patients after an AMI. The study will apply the principles of 
randomization, stratification (by intended P2Y12 inhibitor use [ticagrelor/prasugrel versus 
clopidogrel] after hospital discharge) and double-blinding in order to prevent  bias in the 
inclusion of patients or reporting of safety or efficacy events. 
In addition, the study will follow a parallel group design in order to prevent bias in the data 
due to e.g. different sites in different countries enrolling at different timepoints into the study 
or in case of any seasonally related differences. There does not appear to be a requirement for 
a dose escalation approach, because based on the available preclinical and clinical data for 
BAY2433334 there are no safety concerns related to the highest dose of 50 mg once daily 
tested in the study. 
The study is placebo controlled and will allow to test whether the addition of BAY 2433334 
on top of the standard therapy with dual antiplatelet therapy leads to a lower incidence of 
major CV events (CV death, stroke, MI and stent thrombosis) and without increasing the 
incidence of bleeding.
CV death, MI, stroke and stent thrombosis are used to assess efficacy in this study and have 
been used as endpoints in earlier studies in patients with an acute coronary syndrome or acute

myocardial infarction. Bleeding will be primarily assessed using the BARC bleeding 
definition. 
Participants will be treated on top of dual or later single antiplatelet therapy as prescribed by 
their treating physician. The choice of P2Y12 inhibitor therapy (ticagrelor, clopidogrel or 
prasugrel) and duration of treatment with DAPT after hospital discharge for the index AMI, 
will be left to the discretion of the treating physician and should follow local standard of care 
guidelines. Thus, the study background therapy will reflect how patients are normally treated 
and also allows to assess the combination of the study drug with different P2Y12 inhibitors 
(clopidogrel, ticagrelor, prasugrel) rather than requiring the same for all participants.
4.3
Justification for Dose
The study will test the once daily dose of 10 mg (low dose), 20 mg (mid dose) and 50 mg 
(high dose) dose of BAY 2433334. 
The selection of the high dose in  this study was not limited by the safety and tolerability data 
from toxicology studies, nor from the results of the human Phase 1 studies conducted in 
healthy volunteers.  Single doses up to 150 mg or multiple doses up to 100 mg once daily for 
9 days were tested in the Phase I studies. Due to these favorable results , the dose selection for 
the Phase 2 studies was primarily based on pharmacodynamic assays (preclinical and Phase 1 
studies) including aPTT and FXIa activity. 
Modeling approaches of the available Phase 1 data were used to predict the doses for Phase 2 
studies with the goal to select doses that cover a broad range of inhibition of FXIa and lead to 
different degrees of increases in aPTT (Table 4–1).

The high dose of 50 mg was chosen to reach significant inhibition of FXIa and to 
achieve maximum efficacy. However this dose should not lead to a complete 
inhibition of FXIa during the majority of the day. The selected 50 mg dose is expected 
to lead to a mean FXIa activity of 7 % with FXIa activity <10% during 14 hours of the 
day. aPTT is predicted to increase to 
 at trough and 
 at peak. 

The mid dose of 20 mg was selected as the second dose to reflect a linear dose 
response related to FXIa inhibition. This dose leads to a mean FXIa activity of 23%

10 mg was selected as the low dose, as lower doses lead to no or only minimal 
increases in aPTT. For the 10 mg dose, the expected mean FXIa activity is 45% and 
aPTT is increased to 
 at trough and 
 at peak.

Study Intervention
Study intervention is defined as any investigational intervention(s), marketed product(s), 
placebo or medical device(s) intended to be administered to a study participant according to 
the study protocol.
6.1
Study Intervention(s) Administered
The following study interventions will be administered in the study:

BAY 2433334: sponsor’s study drug under investigation

Placebo to BAY 2433334
BAY 2433334 is supplied in various strengths as film-coated, immediate-release tablets  with 
identical appearance. The immediate release tablets will be provided as pink, oval, film-
coated tablets containing either 5 mg, 15 mg or 25 mg of BAY 2433334 (Table 6–1).
The study intervenions (tablets) are not to be broken, halved or crushed, and should be 
swallowed whole with a glass of water in the morning. Participants will have to take two 
tablets from two different bottles (one tablet from each bottle) for one dose. Study drug 
(tablets) can be taken irrespective of food intake.
Matching placebos for BAY 2433334 are supplied in the same way. 
Missed study intervention dose
The planned double-blind treatment phase starts at randomization and ends at week 52 or the 
study treatment end date (i.e. 26 weeks after the last participant of the study has been 
randomized), whichever is earlier, or when study drug is permanently discontinued. Study 
drug will start as soon as possible after randomization (day 1), and is expected to continue 
through the end of the planned treatment period as described above.
If a dose of study intervention is missed, the participant should take a dose immediately on 
the same day. The dose should not be doubled to make up for a missed dose.

All study interventions will be labelled according to the requirements of local regulations.
For administered study interventions, a system of numbering in accordance with all 
requirements of Good Manufacturing Practice (GMP) will be used, ensuring that each dose 
can be traced back to the respective bulk batch of the ingredients.
A complete record of batch numbers and expiry dates of all investigational interventions and 
placebo as well as the labels will be maintained in the sponsor’s study file.
In all cases BAY 2433334 or placebo is administered on top of standard of care, consisting of 
antiplatelet therapy. The choice of antiplatelet therapy will be left to the discretion of the 
treating physician and can include single or dual antiplatelet therapy (see Section 6.5.1).
The choice of background antiplatelet therapy will be documented in the patient records and 
captured in the eCRF.

Preparation/Handling/Storage/Accountability
All study interventions will be stored at the investigational site in accordance with Good 
Clinical Practice (GCP) and Good Manufacturing Practice (GMP) requirements and the 
instructions given by the clinical supplies department of the sponsor or its affiliates.
1. The investigator or designee must confirm appropriate temperature conditions have 
been maintained during transit for all study intervention received and any 
discrepancies are reported and resolved before use of the study intervention.
2. Only participants enrolled in the study may receive study intervention and only 
authorized site staff may supply or administer study intervention. All study 
intervention must be stored in a secure, environmentally controlled, and monitored

(manual or automated) area in accordance with the labeled storage conditions with 
access limited to the investigator and authorized site staff.
3. The investigator, institution, or the head of the medical institution (where applicable) 
is responsible for study intervention accountability, reconciliation, and record 
maintenance (ie, receipt, reconciliation, and final disposition records).
4. Further guidance and information for the final disposition of unused study 
interventions are provided in the Investigator Site File. 
6.3
Measures to Minimize Bias: Randomization and Blinding
All participants will be centrally assigned to randomized study drug using an InteractiveWeb 
Response System (IWRS). To accomplish random assignments, computer-generated 
randomization lists specified by the sponsor's responsible statistician will be prepared by 
Randomization Management at the study sponsor. The randomization lists are provided to an 
IWRS vendor. Before the study is initiated, the log in information & directions for the IWRS 
will be provided to each site.
The randomization will be stratified based on the intended P2Y12 inhibitor use 
(ticagrelor/prasugrel versus clopidogrel) after hospital discharge.
Study drug will be dispensed at the study visits summarized in SoA (Section 1.3). 
Returned study intervention should not be re-dispensed to the participants.
Patients will be randomly assigned in a [1:1:1:1] ratio to receive study drug. Investigators will 
remain blinded to each participant’s assigned study intervention throughout the course of the 
study. 
Tablets containing 5 mg, 15 mg or 25 mg of BAY 2433334 and corresponding placebo are 
identical in appearance (size, color, shape). In order to maintain the blind study drugs will be
packed in bottles labeled with a unique number which will be pre-printed on each bottle. In 
addition, participants will be provided with 2 bottles either with active drug or placebo 
depending on the randomization outcome.
6.3.1
Unblinding
The IWRS will be programmed with blind-breaking instructions. In case of an emergency, the 
investigator has the responsibility for determining if unblinding of a patient’s treatment 
assignment is warranted. If the investigator is unavailable, and a treating physician not 
associated with the study requests emergency unblinding, the emergency unblinding requests 
are forwarded to the study specific emergency medical advice 24 hours/7 day service. 
Participant safety must always be the first consideration in making such a determination. If 
the investigator decides that unblinding is warranted, the investigator should make every 
effort to contact the sponsor prior to unblinding a patient’s treatment assignment unless this 
could delay emergency treatment of the patient. If a patient’s treatment assignment is 
unblinded, the sponsor must be notified within 24 hours after breaking the blind. The date and 
reason that the blind was broken must be recorded in the source documentation and case 
report form, as applicable.

BAY 2433334 is known to prolong the activated partial thromboplastin time (aPTT) in a dose 
depended manner. aPTT is a commonly used functional coagulation test widely used in 
clinical practice in patients using anticoagulants and is as well commonly used during acute 
hospitalizations, and as a pre-procedural screening test. Thus, inadverted unblinding of the 
participant or investigator might take place in cases where aPTT test results are known.
Therefore, the measurement of aPTT during the study conduct is strongly discouraged and 
should only be done in case of an (emergency) situation, where aPTT may help to guide 
treatment decision. aPTT determinations as part of the study will not be reported to 
investigator during the study in order to maintain the blinding. 
6.4
Study Intervention Compliance
Participant compliance with study intervention will be assessed at each visit by direct 
questioning. At each dispensing visit (V6, V8 and V10) and at EoT (V12) or ET (V12a) visit, 
compliance will be assessed by counting returned tablets/capsules. Deviation(s) from the 
prescribed dosage regimen should be recorded in the eCRF.
To monitor compliance, the investigator will be required to document drug dispensing and 
return for each participant. Overall compliance with study intervention intake should be 
between 80% and 120% of the scheduled dose at the end of study  treatment. The date of 
dispensing the study intervention to the participant will be documented. Study intervention
will be dispensed according to the schedule provided in the SoA (Section 1.3). 
Participants should be instructed to bring all unused study intervention and empty packages at 
Visit 6 , 8, 10 and EoT (or ET) visit for accountability purposes. Any discrepancies between 
actual and expected amount of returned study medication must be discussed with the 
participant the time of the visit, and any explanation must be documented in the source 
records.
6.5
Prior and Concomitant Therapy
Any relevant medication or vaccine (including over-the-counter or prescription medicines, 
vitamins, and/or herbal supplements) that the participant is receiving at the time of enrollment 
or receives during the study must be recorded along with:

Reason for use

Dates of administration including start and end dates

Dosage information including dose and frequency
The Medical Monitor should be contacted if there are any questions regarding concomitant or 
prior therapy.
Special focus needs to be given to  antiplatelet and anticoagulant medications. Any use in the 
week before the index AMI event, prior to screening, as well as  concomitant use from study 
entry until the last scheduled study visit of the participant, needs to be captured on the 
specified concomitant medication page.

The concomitant use of NSAID therapy during the study is strongly discouraged since this 
has been shown to increase the risk of gastrointestinal (GI) bleeding. However, if a NSAID 
drug must be temporarily used, it is recommended that the lowest possible dosage for the 
shortest duration possible be selected, not to exceed 4 weeks. Should analgesics be needed, 
use of paracetamol/acetaminophen is recommended. 
Concomitant therapy with any of the following drugs is prohibited from 14 days (or at least 
five half-lives of the active substance, whatever is longer) before first study intervention 
administration, until at least 48 hours after last study intervention administration:

Strong inhibitors of cytochrome P450 isoenzyme 3A4 (CYP3A4) e.g. human 
immunodeficiency virus protease inhibitors (ritonavir, indinavir, nelfinavir, atazanavir, 
or saquinavir), systemically used azole antimycotic agents (ketoconazole, itraconazole, 
voriconazole, or posaconazole), clarithromycin, telithromycin

Strong inducers of CYP3A4, e.g. phenytoin, carbamazepine, phenobarbital, rifampicin, 
or St. John’s wort
A separate complete list with prohibited medications will be provided to the investigator.
6.5.1
Concomitant Antiplatelet Therapy
In all cases, the investigational BAY 2433334 or placebo is administered on top of standard of 
care treatments for post-MI patients, consisting of dual antiplatelet therapy and later single 
antiplatelet therapy. The choice of P2Y12 inhibitor therapy (ticagrelor, clopidogrel or 
prasugrel) and duration of treatment with DAPT after hospital discharge for the index AMI ,
will be left to the discretion of the treating physician and should follow local standard of care 
guidelines. The use of the antiplatelet background therapy (ASA and P2Y12 inhibitors) will be 
documented on the eCRF .
6.5.2
Guidance for Management of Participants who have Bleeding During 
the Study
If a participant has serious bleeding during the study treatment period that requires 
hospitalization, the following routine measures should be considered:

Temporarily or permanently discontinue the randomized study medication. The 
decision to discontinue study drug, temporarily or permanently, will be at the 
discretion of the treating physician and must be documented.

Temporarily discontinue antiplatelet therapies (aspirin and/or the chosen P2Y12 
inhibitor) until the bleeding event is sufficiently controlled, based upon the discretion 
of the treating physician.

Investigate other causes of serious bleeding such as coagulopathies, 
thrombocytopenia, kidney/liver dysfunction, or other concomitant medications. 

Consider usual supportive treatments for bleeding, including local control of bleeding
through standard procedures based upon the bleeding location, fluid replacement, 
blood transfusion, and fresh frozen plasma (FFP) transfusion. Consideration may also
be given to the use of an antifibrinolytic agent, such as tranexamic acid or ε-amino 
caproic acid (Tomaselli et al. 2017) .

If bleeding cannot be controlled by the above measures, consider urgent surgical or non-
surgical procedures to stop the bleeding (emergency surgery, arterial embolization, 
endoscopic cauterization, etc) and unblinding of the randomized treatment assignment.                
For those participants treated with BAY 2433334, administration of the procoagulants can 
also be considered, but there are no definite data to support the use of these agents.
6.5.3
Guidance for management of participants who have  non-cardiac 
surgery or non-cardiac percutaneous/endoscopic procedures 
When possible, non-cardiac surgery and non-cardiac percutaneous/endoscopic procedures 
should be planned and delayed for at least 24 hours to allow for a 24-hour washout period 
after temporary discontinuation of randomized study drug to mitigate risks of bleeding.  
For urgent or emergent non-cardiac surgery or non-cardiac percutaneous/endoscopic 
procedures, when waiting for 24 hours is not an option to allow for study drug wash out after 
temporary discontinuation, the increased risks of procedural bleeding should be assessed 
against the urgency of the procedure based upon the clinical situation. Peri-procedure 
management may in part, depend on the randomized treatment assignment (BÀY 2433334 or 
placebo) and unblinding of treatment assignment may be necessary. In general, the treatment 
recommendations should follow the Guidelines for Severe Perioperative Bleeding 
Management (Kozek-Langenecker SA et al. 2013). The procedure should be conducted in 
such a way to minimize the risk of bleeding.
Treatment of participants receiving BAY 2433334 during urgent or emergency non-cardiac 
procedures may be guided by published data regarding patients with an inherited FXI 
deficiency. Apart from giving FXI concentrate (FXI) as replacement therapy to cover a 
surgical bleeding event (Ling et al. 2016), there have been reports in the literature about the 
successful use of tranexamic acid or ε-amino caproic acid for the management of these 
patients with a FXI deficiency when undergoing surgery (Duga and Salomon 2013). More 
detailed information may be found in the Investigator’s Brochure.
6.5.4
Guidance for management of participants who experience a suspected 
ischemic stroke during the study
The treatment assignment may have to be emergently unblinded if necessary, to facilitate 
management decisions (e.g. intravenous thrombolysis or intra-arterial thrombolysis in case of 
mechanical clot removal). 
For participants with acute ischemic stroke who are receiving BAY 2433334, the risk of 
bleeding with use of intravenous thrombolysis is unknown and has not been studied; hence a 
clear recommendation in this situation cannot be given. However, it is not recommended that 
a thrombolytic agent be given unless it is known that the study intervention (BAY 2433334)
has not been taken in the previous 48 hours, and the aPTT is normal. In this case, the risk of 
bleeding associated with thrombolysis is not expected to be increased (and unblinding may 
not be necessary).
For participants who undergo thrombolysis; study medication should be withheld until at least 
24 hours after thrombolysis.

Mechanical clot removal (thrombectomy) without thrombolysis may be performed in any
case. 
6.5.5
Guidance for management of participants who experience a suspected 
new, acute recurrent cardiac ischemic event during the study
For participants who experience a suspected new, acute recurrent cardiac ischemic event 
requiring unplanned hospitalization (unstable angina or AMI), standard of care medications 
should be administered according to local practice guidelines and based upon the chosen 
invasive procedure (dual antiplatelet therapy, if not already being used, 
intravenous/subcutaneous anticoagulants, or intravenous antiplatelet therapies such as 
glycoprotein IIb/IIIa inhibitors or cangrelor).  Study intervention does not need to be
discontinued upon hospital presentation for a suspected acute recurrent cardiac ischemic 
event.  Recurrent cardiac ischemic event (AMI) endpoint reporting guidelines and processes 
should be followed for these situations.
For participants who undergo urgent or emergent coronary angiography (with or without 
PCI) as treatment for the new recurrent ischemic event, continuation of blinded study 
intervention and concomitant peri-procedural use of standard parenteral or subcutaneous 
anticoagulants (unfractionated heparin, bivalirudin, low molecular weight heparin) during PCI 
is recommended. 
For participants who are treated with urgent or emergent CABG surgery, study drug should be 
stopped (if possible) 24 hours before the surgery and restarted no earlier than 24 hours after 
the post-surgical drains (chest tubes) have been removed.
The treatment assignment may have to be emergently unblinded to facilitate decisions 
regarding treatment with intravenous fibrinolytics for acute ST-elevation MI. For participants 
who are receiving BAY 2433334, the risk of bleeding related to the concomitant use of an 
intravenous fibrinolytic is unknown and has not been studied.  For participants treated with 
intravenous fibrinolytics, study drug should be restarted no earlier than 24 hours after 
receiving fibrinolytics.
6.5.6
Guidance for management of participants who undergo elective 
coronary angiography, PCI, or CABG during the study 
For participants who undergo elective (scheduled) coronary angiography, with or without 
elective PCI after randomization or in case of a staged PCI procedure for the index AMI event
continuation of blinded study intervention and concomitant peri-procedural use of standard 
parenteral or subcutaneous anticoagulants (unfractionated heparin, bivalirudin, low molecular 
weight heparin) during PCI is recommended. For participants who undergo elective CABG 
surgery , study intervention should be temporarily discontinued for at least 24 hours before 
elective CABG is performed. Study intervention should be restarted no earlier than 24 hours 
after the post-surgical drains (chest tubes) have been removed.

Intervention after the End of the Study
No further study intervention is planned following the End of the Study. For the definition of

Any further therapy at the end of the study is at the discretion of investigator/treating 
physician.
7.
Discontinuation of Study Intervention and Participant 
Discontinuation/Withdrawal 
7.1
Discontinuation of Study Intervention 
In rare instances, it may be necessary for a participant to permanently discontinue (definitive 
discontinuation) study intervention. If study intervention is definitively discontinued, the 
participant will remain in the study to be evaluated for bleeding and efficacy outcome events 
until the planned regular end of treatment. See the SoA for data to be collected at the time of 
discontinuation of study intervention and follow-up and for any further evaluations that need 
to be completed.
An ET visit is only applicable to participants who prematurely discontinue intake of study 
intervention; such participants should undergo the ET visit as soon as possible, after 
permanent discontinuation of study intervention. A safety follow up visit (telephone call) will 
occur 14 days after the day of the premature discontinuation of study intervention (+ 7 days 
window). If the ET visit falls into the time window for the safety follow up visit (≥ 2 weeks 
after permanent discontinuation of study intervention), a safety follow up visit will not be 
performed.
In this study, outcome events and vital status data are crucial to the primary analysis and must 
be collected until the end of the study, as participants will still be part of the study even if they 
are no longer taking study medication.  Therefore, all efforts will be taken to motivate 
participants to comply with all study procedures and to continue to be followed until the end 
of the study for each participant (i.e. 26 to 52 weeks).
Study intervention will not be routinely discontinued in participants reaching a potential 
outcome event or in case of unblinding unless there is a safety concern or a clear indication 
for an alternative antithrombotic therapy as determined by the local investigator.
Specifically, a permanent discontinuation of study intervention will be required, if 
concomitant treatment with any of the following medications has to be taken for the 
remaining duration of the study conduct:

requirement of full dose and long term anticoagulation therapy during study conduct  
(e.g de novo atrial fibrillation, pulmonary embolism)

strong CYP3A4 inhibitors as well as strong CYP3A4 inducers. 
Discontinuation of study intervention for abnormal liver function should be considered by the 
investigator when a participant meets one of the conditions outlined below or if the 
investigator believes that it is in best interest of the participant (please also refer to Section 
10.5 for the requirements for liver function monitoring)


ALT or AST > 3 x ULN with the appearance of fatigue, nausea, vomiting, right upper 
quadrant pain or tenderness, fever, rash, and / or eosinophilia (> 5%) 
See the SoA for data to be collected at the time of premature intervention discontinuation (ie, 
ET visit) and follow-up and for any further evaluations that need to be completed. 
At time of permanent discontinuation of the study intervention, the participant is expected to 
continue regular study clinic visits at the investigator’s site as outlined in the protocol.
If this is not possible for any reason, the investigator and participant must discuss and
determine further follow-up options, as listed below, in descending order of preference:
1. Participant will be contacted by phone at the regular follow-up intervals
2. Participant allows his / her treating physician, e.g. general practitioner or a family 
member, to be contacted or his medical file checked at the regular follow-up interval, 
or at least once at study end (if allowed in respective country)
3. Participant will be contacted once at the planned End of Treatment period (Planned 
regular EoT visit for the participant)
After permanent discontinuation of the study intervention, the following will need to be 
collected at the regular study visits and up to the regular end of treatment visit, preferentially 
directly from the participant and as agreed to by the participant during the initial informed 
consent process:

Vital Status

Antiplatelet and anticoagulant medications

Outcome events (MI, stroke, death, bleeding, stent thrombosis).
If a participant is unwilling or unable to return for follow-up visits in person or have follow-
up contacts, sites should collect as much follow-up visit information as possible, including 
contacting the participant or the participant’s representative, family member or treating 
physician by telephone or by mail. If applicable, vital status may be obtained by reviewing the 
participant’s medical or public sources (e.g. social media, health insurance, public [death]
registry), unless this process is not allowed by local regulations.
Withdrawal of Consent
Note: None of the above options is considered a withdrawal of consent.
A withdrawal of consent should only occur in exceptional cases and means that the participant 
does not agree to any kind of follow-up and specifically refuses any further contact with the 
investigator (see Section 7.2)

7.1.1
Temporary Discontinuation 
In case of a temporary study medication interruption for any reason, study medication will be 
restarted as soon as medically justified in the opinion of the investigator.  There is no defined 
maximum limit for temporary treatment interruption.  
If study interventions were temporarily stopped, PK/PD blood samples should only be 
obtained if study interventions have been restarted and sustained for at least 4 days.
7.2
Participant Discontinuation/Withdrawal from the Study

A participant may withdraw from the study at any time at his/her own request, or may 
be withdrawn at any time at the discretion of the investigator for safety, behavioral 
compliance, or administrative reasons. This is expected to be uncommon.

At the time of discontinuing from the study, if possible, an early discontinuation visit 
should be conducted, as shown in the SoA. See SoA for data to be collected at the 
time of study discontinuation and follow-up and for any further evaluations that need 
to be completed.

The participant will be permanently discontinued both from the study intervention and 
from the study at that time.

If the participant withdraws consent for disclosure of future information, the sponsor 
may retain and continue to use any data collected before such a withdrawal of consent.

At the time of informed consent, participants will be explained all the options to 
continue in the study after permanent discontinuation of study intervention (see 
Section 7.1). This will be re-discussed at the time of permanent discontinuation of 
study intervention and the participant’s specific agreement will be documented. 
Participants will agree to be contacted to obtain follow-up information should they 
decide to stop the intervention.

When a participant withdraws consent from study participation before completing the 
study, meaning that the participant does not agree to any kind of follow-up and 
specifically refuses any further contact with the investigator, the reason for consent 
withdrawal is to be documented in the source document. Public information can be 
used to obtain vital status for these participants where allowed by local regulations.
7.3
Lost to Follow Up
A participant will be considered lost to follow-up if he or she repeatedly (twice) fails to return 
for scheduled visits and is unable to be contacted by the study site. 
The following actions must be taken if a participant fails to return to the clinic for a required 
study visit:

The site must attempt to contact the participant and reschedule the missed visit as soon 
as possible and counsel the participant on the importance of maintaining the assigned 
visit schedule and ascertain whether or not the participant wishes to and/or should 
continue in the study.


Before a participant is deemed lost to follow up, the investigator or designee must 
make every effort to regain contact with the participant (where possible, 3 telephone 
calls and, if necessary, a certified letter to the participant’s last known mailing address 
or local equivalent methods). These contact attempts should be documented in the 
participant’s medical record.

Should the participant continue to be unreachable, he/she will be considered lost to 
follow up.

In order to reduce risk for lost to follow-up the site should collect 2 alternative means 
of contact for each participant e.g. contact information of the participant’s children, 
caretaker, legal representative, or primary physician. The correctness of these contact 
details should be checked regularly at the study visits.

A patient locator service may be used to re-establish contact with a participant in case 
the site has exhausted all means of regaining contact, if the participant will agree to 
this in the ICF.
8.
Study Assessments and Procedures

Study procedures and their timing are summarized in the SoA (Section 1.3). Protocol 
waivers or exemptions are not allowed.

Immediate safety concerns should be discussed with the sponsor immediately upon 
occurrence or awareness to determine if the participant should continue or discontinue 
study intervention.

Adherence to the study design requirements, including those specified in the SoA, is 
essential and required for study conduct.

All screening evaluations must be completed and reviewed to confirm that potential 
participants meet all eligibility criteria. The investigator will maintain a screening log 
to record details of all participants screened and to confirm eligibility or record 
reasons for screening failure, as applicable. 

Procedures conducted as part of the participant’s routine clinical management (e.g., 
blood count) and obtained before signing of the ICF may be utilized for screening or 
baseline purposes provided the procedures met the protocol-specified criteria and were 
performed within the time frame defined in the SoA.
8.1
Efficacy Assessments 
The efficacy assessments include primary and secondary endpoints of the study (see Section 
3).
8.1.1
Primary Efficacy Endpoint
The primary efficacy endpoints of the study include the analysis of a composite of:

CV death

MI

Stroke (ischemic and hemorrhagic)


Stent thrombosis
A definition of the primary efficacy outcome events is provided as follows and further 
specified in the charter of the clinical event committee (CEC). Details on the time periods for 
collecting Outcome Events information are reported in Section 10.8.
8.1.1.1
Cardiovascular Death
Cardiovascular death includes death due to stroke, myocardial infarction, heart failure or 
cardiogenic shock, sudden death or any other death due to other cardiovascular causes.  In 
addition, death due to non-traumatic hemorrhage will be included.
8.1.1.2
Myocardial Infarction
The term acute myocardial infarction (MI) is used when there is evidence of myocardial 
necrosis in a clinical setting consistent with acute myocardial ischemia. According to the MI 
Universal Definition from 2018 (Thygesen et al. 2018) the diagnosis of MI requires the 
combination of:

Presence of acute myocardial injury (changes in cardiac biomarkers) and

Evidence of acute myocardial ischemia derived from the clinical presentation, 
electrocardiographic changes, or the results of myocardial or coronary artery imaging, 
or in case of post-mortem pathological findings irrespective of biomarker values.
Five types of myocardial infarction can be differentiated:

Type 1 Spontaneous myocardial infarction

Type 2 MI secondary to an ischemic imbalance

Type 3 MI resulting in death when biomarker values are unavailable

Type 4a MI related to percutaneous coronary intervention (PCI) 

Type 4b MI related to stent thrombosis

Type 4c MI related to re-stenosis associated with PCI

Type 5 MI related to coronary artery bypass grafting (CABG)
8.1.1.3
Stroke   
Stroke is defined as an acute episode of focal or global neurological dysfunction caused by an 
injury of the brain, spinal cord, or retina as a result of hemorrhage or infarction.
Differentiation is made regarding ischemic stroke and hemorrhagic stroke.
Hemorrhagic stroke is defined as an acute, atraumatic extravasation of blood into the brain 
parenchyma, intraventricular, or subarachnoid space with associated neurological symptoms. 
This does not include microbleeds nor hemorrhagic transformation of an ischemic stroke. 
An ischemic stroke is defined as rapid onset (or presence on awakening) of a new focal 
neurological deficit with clinical (≥ 24 hours symptoms / signs) or imaging evidence of 
infarction that is not attributable to a non-ischemic cause (i.e. not associated with infection, 
tumor, seizure, severe metabolic disease).

The term undetermined stroke will apply when sudden focal neurological deficits persist for 
24 hours (or death if occuring before 24 hours) but without neuroimaging or autopsy.
8.1.1.4
Stent Thrombosis
Uniform definitions have been developed and were updated by the Academic Research 
Consortium-2 (ARC-2), incorporating diagnostic certainty as well as timing 
Definition Based on Diagnostic Certainty of Stent Thrombosis (ST) (Garcia-Garcia et al. 
2018):

“Definite” ST: The highest level of certainty. Either angiographic or pathological 
confirmation of stent thrombosis. 

“Probable” ST: Regardless of the time after the index procedure, any myocardial 
infarction that is related to documented acute ischemia in the territory of the implanted 
stent without angiographic confirmation of stent thrombosis and in the absence of any 
other obvious cause
In this trial the categories of  “probable” ST are excluded and only “definite” ST is selected as 
endpoint.
Definition Based on Timing of Stent Thrombosis (ST):

Acute ST*: 0 to 24 hrs after stent implantation

Subacute ST*: >24 hours to 30 days after stent implantation

Late ST: >30 days to 1 year after stent implantation

Very late ST: >1 year after stent implantation
*Acute or subacute can also be summarized under the term early stent thrombosis
(0 to 30 days).
8.1.2
Secondary Efficacy Endpoint
The secondary efficacy endpoints of the study include the individual components of the CV 
death, MI, stroke, stent thrombosis and all cause mortality.
A definition of the efficacy outcome events is provided in Section 8.1.1 and further specified 
in the Clinical Event Committee Charter.
8.2
Safety Assessments 
The safety assessments include primary, secondary and exploratory endpoints of the study. At 
each visit during the study as specified in the SoA, the investigator will evaluate the 
participant for the occurrence of bleeding events. All necessary information to classify 
bleeding events according to the ISTH, the Thrombolysis In Myocardial Infarction (TIMI) 
and the Bleeding Academic Research Consortium (BARC) criteria will be collected in the

*overt bleeding requires the identification of the bleeding location and the hemoglobin drop 
and/ or transfusion needs to be related to the bleeding
8.2.2.3
ISTH Clinically Relevant Non-Major Bleeding
Clinically relevant non-major bleeding is considered any sign or symptom of hemorrhage that 
does not fit the criteria for the ISTH definition of major bleeding, but does meet at least one of 
the following criteria (Kaatz et al. 2015):

requiring medical intervention by a healthcare professional

leading to hospitalization or increased level of care

prompting a face to face (i.e. not just a telephone or electronic communication) 
evaluation
8.2.3
Physical Examinations

Height and weight (also referred to as biometrics in the SoA) will be measured and 
recorded at screening (see Section 1.3).
8.2.4
Vital Signs

Blood pressure and pulse measurements will be assessed with a completely automated 
device. Manual techniques will be used only if an automated device is not available.

Blood pressure and pulse measurements should be preceded by at least 5 minutes of 
rest for the participant in a quiet setting without distractions (eg, television, cell 
phones).

Electrocardiograms

A single12-lead ECG will be obtained as outlined in the SoA (see Section 1.3) using 
an ECG machine that automatically calculates the heart rate and measures PR, QRS, 
QT, and QTc intervals. 
8.2.6
Clinical Safety Laboratory Assessments

See Section 10.2 for the list of clinical laboratory tests to be performed and to the SoA 
for the timing and frequency. 

The investigator must review the laboratory report, document this review, and record 
any clinically relevant changes occurring during the study in the AE section of the 
CRF. The laboratory reports must be filed with the source documents. Clinically 
significant abnormal laboratory findings are those which are not associated with the 
underlying disease, unless judged by the investigator to be more severe than expected 
for the participant's condition.

All laboratory tests with values considered clinically significantly abnormal during 
participation in the study or within 14 days after the last dose of study intervention 
should be repeated until the values return to normal or baseline or are no longer 
considered clinically significant by the investigator or the medical monitor.
o
If such values do not return to normal/baseline within a period of time judged 
reasonable by the investigator, the etiology should be identified and the sponsor 
notified.
o
All protocol-required laboratory assessments, as defined in Section 10.2, must be 
conducted in accordance with the laboratory manual and the SoA. 
o
If laboratory values from non-protocol specified laboratory assessments 
performed at the institution’s local laboratory require a change in participant 
management or are considered clinically significant by the investigator (eg, SAE 
or AE or dose modification), then the results must be recorded in the CRF. 
8.3
Adverse Events and Serious Adverse Events
The definitions of an AE or SAE can be found in Section 10.3.
Events identified as Adverse Events of Special Interest (AESI) for the study are specified in 
Section 8.3.7
AEs that are outcome events according to the study protocol are further described in Section 
8.3.6 and Section 10.3.5.
AEs will be reported by the participant (or, when appropriate, by a caregiver, surrogate, or the 
participant's legally authorized representative).
The investigator and any qualified designees are responsible for detecting, documenting, and 
recording events that meet the definition of an AE or SAE. They remain responsible for 
following up SAEs or AEs considered related to the study intervention or those that caused 
the participant to discontinue the study intervention and/or study. AESIs have to be followed 
up regardless of causality or relationship to the study intervention.

8.3.1
Time Period and Frequency for Collecting AE and SAE Information 
All SAEs will be collected from the start of intervention (first day of study intervention 
intake) until the safety follow-up visit at the time points specified in the SoA (Section 1.3).
All AE will be collected from the start of intervention until the safety follow-up visit at the 
time points specified in the SoA (Section 1.3).
Medical occurrences that begin before the start of study intervention but after obtaining 
informed consent will be recorded on the Medical History/Current Medical Conditions 
section of the case report form (CRF) not the AE section.
All SAEs will be recorded and reported to the sponsor or designee immediately and under no 
circumstances should this exceed 24 hours after the investigator becomes aware of this event, 
as indicated in Section 10.3. The investigator will submit any updated SAE data to the 
sponsor within 24 hours of it being available.
Investigators are not obligated to actively seek AE or SAE after conclusion of the study 
participation. However, if the investigator learns of any SAE, including a death, at any time 
after a participant has been discharged from the study, and he/she considers the event to be 
reasonably related to the study intervention or study participation, the investigator must 
promptly notify the sponsor. 
8.3.2
Method of Detecting AEs and SAEs
The method of recording, evaluating, and assessing causality of AE and SAE and the 
procedures for completing and transmitting SAE reports are provided in Section 10.3.
Care will be taken not to introduce bias when detecting AEs and/or SAEs. Open-ended and 
non leading verbal questioning of the participant is the preferred method to inquire about AE 
occurrences. 
8.3.3
Follow-up of AEs and SAEs
After the initial AE/SAE report, the investigator is required to proactively follow each 
participant at subsequent visits/contacts. All SAEs, and serious and non-serious AEs of 
special interest (as defined in Section 8.3.7), will be followed until resolution, stabilization, 
the event is otherwise explained, or the participant is lost to follow-up (as defined in Section 
7.3). Further information on follow-up procedures is provided in Section 10.3. 
8.3.4
Regulatory Reporting Requirements for SAEs

Prompt notification by the investigator to the sponsor of an SAE is essential so that 
legal obligations and ethical responsibilities towards the safety of participants and the 
safety of a study intervention under clinical investigation are met. 

The sponsor has a legal responsibility to notify both the local regulatory authority and 
other regulatory agencies about the safety of a study intervention under clinical 
investigation. The sponsor will comply with country-specific regulatory requirements 
relating to safety reporting to the regulatory authority, Institutional Review Boards 
(IRB)/Independent Ethics Committees (IEC), and investigators.


For all studies except those utilizing medical devices, investigator safety reports must 
be prepared for suspected unexpected serious adverse reactions (SUSAR) according to 
local regulatory requirements and sponsor policy and forwarded to investigators as 
necessary.

An investigator who receives an investigator safety report describing an SAE or other 
specific safety information (e.g., summary or listing of SAEs) from the sponsor will 
review and then file it along with the Investigator’s Brochure and will notify the
IRB/IEC, if appropriate according to local requirements.
8.3.5
Pregnancy

Details of all pregnancies in female participants and, if indicated, female partners of 
male participants will be collected after the start of study intervention and until 94 
days after the last dose intake.

If a pregnancy is reported, the investigator should inform the sponsor within 24 hours 
of learning of the pregnancy and should follow the procedures outlined in Section 
10.4.

Abnormal pregnancy outcomes (e.g., spontaneous abortion, fetal death, stillbirth, 
congenital anomalies, ectopic pregnancy) are considered SAEs.
8.3.6
Disease-Related Events  
During the study there will be incidences where AEs are also potential efficacy or safety 
endpoints.
In compliance with applicable regulations, in the event of a SUSAR (see Section 8.3.4) 
related to the blinded treatment, the participant’s treatment code will usually be unblinded 
before reporting to the health authorities. Notifications of ethic committees and investigators 
will be done according to all applicable regulations (see Section 10.3.4).
The following disease- and treatment-related events are common in participants with acute 
myocardial infarction who are being treated with an anticoagulant:
a.
Bleeding
b. Death 
c.
Myocardial Infarction 
d. Ischemic stroke
e.
Stent thrombosis
These events will be recorded on the corresponding CRF page in the participant’s CRF.
These events will also be monitored and adjudicated by a Central Event Committee (CEC) on 
an ongoing basis.
In addition, these events require reporting to the sponsor according to the standard process of 
expedited reporting of SAEs within 24 hours of the investigator’s awareness of the event, 
along the timelines set for reporting of SAEs and AESIs.

However, due to their expectedness, efficacy endpoints listed above (b-e: death, myocardial 
infarction, ischemic stroke, and stent thrombosis), including events indicative of those 
outcome events (e.g. TIA, cardiac, chest pain) will not be subject to systematic unblinding 
and expedited SUSAR reporting to health authorities.
8.3.7
Adverse events of special interest
Adverse events of special interest (AESIs) will be all AEs related to hepato-biliary 
dysfunction , i.e. relevant increases in the respective liver lab values (ALT > 3 x ULN or 
AST > 3 x ULN with confirmatory re-testing within 5 days of initial lab value elevation), see 
Section 10.5, with or without symptoms such as e.g. nausea, vomiting, right upper quadrant 
abdominal pain, fatigue, weakness, weight loss and jaundice. Re-testing of lab values can be 
performed at the local lab and needs to be documented in the CRF.
AESIs have to be reported to the sponsor within 24 hours of the investigator’s awareness, i.e. 
along the timelines set for SAEs (even though they may not be classified as serious), as 
described in Section 8.3.1.
8.4
Treatment of Overdose
For this study, any dose of BAY 2433334 greater than 3 assigned daily doses (i.e. more than 6 
tablets) within a 24-hour time period will be considered an overdose.
The sponsor does not recommend specific treatment for an overdose of BAY 2433334, as a 
specific antidote for the study drug is not available. The use of activated charcoal to reduce 
absorption may be considered.
Due to the mechanism of action, an overdose of the study drug could potentially result in 
hemorrhage. In case of bleeding linked to overdose the guidance on bleeding management as 
found in Section 6.5.2 should be followed. 
In the event of an overdose, the investigator/treating physician should:
1.
Contact the Medical Monitor immediately.
2.
Closely monitor the participant for any AE/SAE and laboratory abnormalities until 
study drug can no longer be detected systemically (at least 5 days.).
4.
Document the quantity of the excess dose as well as the duration of the overdose in the 
CRF.
Decisions regarding dose interruptions or modifications will be made by the investigator in 
consultation with the Medical Monitor based on the clinical evaluation of the participant.
8.5
Pharmacokinetics
For the investigation of systemic exposure to BAY 2433334 and its relationship with 
treatment effects, the plasma concentrations of BAY 2433334 and optionally of its metabolite 
M-10 (BAY 2826102) will be determined at different time points using a sparse sampling 
approach in all participating participants. Details about the collection, processing, storage and 
shipment of samples will be provided separately (e.g. in the Laboratory Manual). Study 
personnel responsible for bioanalytics will be unblinded and will have access to the

randomization list. Analysis of samples from participants not treated with BAY 2433334 is 
optional. 
Blood samples will be collected at the time points indicated in the SoA (Section 1.3). PK 
samples obtained at additional time points based on the investigator’s discretion will not 
qualify as a protocol deviation and will be used for PK analysis as well. Deviations from the 
specified sampling intervals will be documented and taken into account for the PK analysis. 
Date and time of the PK sample collection and date and time of most recent study intervention 
intake (ie, both of the PK/PD sampling day, and of the day before that) must be documented.
At Visit 4 and 8, a trough sample for the determination of BAY 2433334 plasma 
concentrations will be drawn before intake of study drug. At this visit, study intervention will 
be administered at the study center by study personnel and the exact time of study drug intake 
on the day before the visit and on the day of the visit and the exact sampling time will be 
recorded in the eCRF. Ideally, the study personnel should contact the participant prior to the 
respective Visit to remind them not to take the study drug as usual in the morning at home. At 
Visit 4 additional post-dose samples will be taken as indicated in the SoA (Section 1.3)
The PK data and the relationship of the BAY 2433334 exposure parameters (e.g. Cmax, AUC) 
with treatment effects might be evaluated using population approaches (e.g. non-linear mixed 
effect modeling) including potential influence of relevant participant co-variables. Analysis 
and report will be done under a separate cover. This evaluation might be started prior to 
database lock: if this is applicable, appropriate measures will be taken to maintain blinding of 
the study team. 
PK samples will be analyzed, using validated analytical methods. Quality control (QC) and 
calibration samples will be analyzed concurrently with study samples. The results of 
calibration samples and QC samples will be reported in the Bioanalytical Report which will 
be included in the CSR for this study.
8.6
Pharmacodynamics
Blood sampling for PD parameters is scheduled for the time points as given in Section 1.3. 
The actual date and time of blood sampling will be documented in the CRF. 
All PD parameters will be measured using validated methods.
Quality control and calibration samples will be analyzed concurrently with study samples. For 
selected PD parameters, the results of QC samples will be reported together with analyte 
concentrations in the Clinical Study Report of this study.
Concentrations of the analyte are calculated according to the method description. Detailed 
method descriptions of all PD methods will be filed with the study report.
The following parameters will be used to assess the PD effects after administration of the 
investigational drug, but will be performed optionally and/or only in a subset of participants:

aPTT will be measured using a coagulation assay via kaolin-trigger

Activated Factor XIa activity (AXIA) will be analyzed using a kaolin-trigger and a 
fluorogenic substrate readout

immunosorbent assay (ELISA).

vWF antigen level and vWF ristocetin cofactor (i.e. vWF functional activity) will be 
analyzed using turbidometric assays.
The study sponsors reserve the right not to conduct all or part of the above mentioned 
analysis.
In addition, blood samples will be taken for exploratory biomarker work (see Section 8.8).
Detailed information about the collection, processing, storage and shipment of the samples 
will be provided separately (e.g. sample handling sheets and / or laboratory manual).

Genetics
Genetic as well as non-genetic analyses will be part of the biomarker investigations in this 
study. See Section 8.8 for details.
8.8
Biomarkers
Exploratory biomarker analyses (scheduled for the time points as given in Section 1.3), that 
might be performed optionally and/or only in a subset of patients are:

NT-proBNP will be measured using an electrochemiluminescence immunoassay 
(ECLIA)

hsCRP will be measured using an immunoturbidometric method

Thrombin-activatable fibrinolysis inhibitor (TAFI) and C1 inhibitor activity will be 
measured using chromogenic substrate assays

TAT and F1.2 will be analyzed using immunoassays
In addition to the biomarkers described above, further biomarkers related to the mode of 
action or the safety of BAY 2433334 and similar drugs may be examined. The same applies 
to further biomarkers deemed relevant to cardiovascular diseases and associated health 
problems. These investigations may include e.g. diagnostic, safety, PD, monitoring, or 
potentially predictive biomarkers. 
Those additional analyses may include genetic as well as non-genetic biomarkers. Genetic 
investigations may be of any kind, except for whole genome sequencing. Results will be 
reported under separate cover, if the evaluations are performed.
Details on the collection, processing, storage, and shipment of biomarker samples will be 
provided in separate documents (e.g., sample handling sheets or lab manual). Samples may be 
stored for a maximum of 15 years (or according to local regulations) following the end of the 
study at a facility selected by the sponsor to enable further analyses.

Statistical Considerations 
9.1
Statistical Hypotheses
The aim of the study is to estimate the incidence of MACE and bleeding events of 
BAY 2433334 and compare it with the incidence of placebo.
No formal hypothesis testing is planned in this study.
9.2
Sample Size Determination 
Approximately 1650 participants will be screened to achieve 1600 randomly assigned to study 
intervention for an estimated total of 400 evaluable participants per intervention group.
With a sample size of 400 participants per treatment arm, an incidence risk for a primary 
safety event of 4.5% at Day 180 for all treatment arms, and a proportion of about 5% of the 
randomized participants not contributing post-randomization information about the 
occurrence of primary bleeding events, it is expected that about 70 participants will have 
experienced a primary safety outcome until Day 180.
With 70 participants with a primary bleeding event and an observed HR of 1.0 for the 
comparison of BAY 2433334 (all doses pooled) to placebo, the upper bound of the 2-sided 
90% CI for the HR will be approximately 1.44. If the true HR is 1.0 the power to observe a 
2-sided 90% CI for the HR below 1.82 is 80%.

Statistical Analyses
9.4.1
Gerenal considerations
The statistical analysis plan (SAP) will be developed and finalized before database lock and 
will describe the participant populations to be included in the analyses, and procedures for 
accounting for missing, unused, and spurious data. This section is a summary of the planned 
statistical analyses of the primary and secondary endpoints and estimands.
The aim of this study is to gain knowledge of the safety profile and the efficacy of 
BAY 2433334.
For the intercurrent event “discontinuation of study treatment” the “treatment policy” strategy 
is chosen for efficacy estimands and the “while on treatment” strategy is chosen for safety 
estimands.
The intercurrent event Death will be handled with the while alive strategy.
Confidence intervals will be two sided 90% - confidence intervals.
Time to event variables will be analyzed using Kaplan-Meier estimates of cumulative risk and 
cumulative hazard functions. The hazard ratios and the corresponding confidence intervals 
will be estimated on separate Cox proportional hazard models for each comparison. No 
comparison of the different doses of BAY 2433334 is planned.  
Efficacy and bleeding outcomes will be analyzed based on time to their first occurrence. The 
incidence risk for outcome events will be estimated separately for the doses of BAY 2433334 
and/or for the pooled doses and/or the 20 and 50 mg doses combined and compared to 
placebo.
The bleeding risk of BAY 2433334 (all doses pooled) as compared to placebo will be 
estimated using the Cox proportional hazards model.
Main Data scope for safety of the trial is the treatment emergent data scope, counting all 
events from first intake of study drug until 2 days after last study drug intake.
The efficacy of BAY 2433334 (20 and 50 mg pooled) as compared to placebo will be 
estimated using the Cox proportional hazards model.
Main Data scope for efficacy of the trial is the ITT data scope, counting all events from 
randomization until end of study
All time-to-event analyses will be stratified by intended P2Y12 inhibitor use 
(ticagrelor/prasugrel versus clopidogrel) if not mentioned different.
All collected events will be analyzed descriptively, using methods like frequency tables and 
others.
The statistical analyses will be performed using SAS; the version used will be specified in the 
statistical analysis plan (SAP).

9.5
Interim Analyses 
Two non-formal interim analyses are planned to be performed in the Phase 2 program to 
assess the efficacy and safety profile of BAY 2433334 during the Phase 2 study conduct. Data 
from this study as well as the two other ongoing Phase 2 studies will be reviewed together 
when the pre-defined criteria for the two interim analyses have been reached. The overall 
approach of the 2 interim analyses is regarded as acceptable, as these are exploratory Phase 2 
studies and not pivotal studies.
Analyses of the unblinded safety and efficacy data will be performed by a third party, i.e. the 
statistical analysis center (SAC) that supports the IDMC and thus, is independent of the study 
team and the sponsor. A small group of academic leaders (Executive Committee) including 
the heads of the three Steering Committees that have been established for the individual 
studies and sponsor representatives will participate in the review of these data. IDMC 
members will also be included in this review. The data will be kept strictly confidential by 
this group and will not be shared with the study team and the SC. Thus, the study integrity

will not be impacted and the study conduct will otherwise not be altered by the results of this 
interim analysis. 
The interim analysis will include selected and predefined study data primarily as aggregated 
data for this individual study but may also include pooling of some data across all three
ongoing Phase 2 studies. 
The first interim analysis will be conducted once about 50% of the participants (800 
participants) with a minor non-cardioembolic ischemic stroke (NIHSS ≤ 7) are enrolled in the 
study 19766 or 3 months MRI data are available for at least 12.5% of participants (200 
participants). If the review confirms the safety profile of BAY 2433334 and raises no concern 
regarding (intracranial) hemorrhage or hemorrhagic transformation of the ischemic stroke, 
Part B of the study 19766 will be initiated, during which from then on participants with more 
severe cases of stroke (NIHSS ≥ 8 and ≤ 15) can also be included as well as participants after 
thrombolysis or endovascular therapy (mechanical thrombectomy). Even though the primary 
focus for this interim analysis is specific for the decision for the stroke study 19766 only, data 
and especially bleeding data from this study and study19765 will be taken into consideration.  
The second interim analysis will occur when sufficient data are available from all three Phase 
2 studies. This interim analysis may occur, when approximately 80% of all planned 
participants, taken all three studies together, are randomized. This meeting will aim to assess 
whether the interim data support decision making on dose and design for a potential Phase 3 
clinical development program while the Phase 2 studies are still ongoing and may allow 
interaction with Health Authorities before final data from the studies are available.  
The timepoints when these two interim analyses occur are difficult to predict and will depend 
e.g. on study start time, number of sites and countries, on the enrollment rate and other factors 
in all three studies. In case the timepoints for the two interim analysis may be close together, 
the decision could be taken to just conduct one interim analysis. 
As part of the two interim analyses the additional objective to potentially change the dose 
during the ongoing Phase 2 studies will be assessed. This will allow flexibility in case of 
unexpected findings during the review of the data, e.g. stop of the highest dose (in case of an 
unexpected higher bleeding rate in the highest dose or in the combination with antiplatelet 
therapy) or addition of a lower or higher dose or replacement of one dose (in case of  a 
difference in pharmacokinetics or PD parameters such as inhibition of FXIa in the patient 
populations compared to healthy volunteers).

Independent Data Monitoring Committee (IDMC)
An independent data monitoring committee (IDMC) will be involved in the review of the 
safety data for study 20603, and of the overall safety data across all three Phase 2 studies with 
BAY 2433334 (Section 10.1.5.3). Detailed information on the roles and responsibilities of the 
IDMC will be described in the IDMC Charter.

Based Monitoring), methods, responsibilities and requirements, including handling of 
noncompliance issues and monitoring techniques (central, remote, or on-site 
monitoring) are provided in the Monitoring Plan.

The sponsor or designee is responsible for the data management of this study 
including quality checking of the data. 

The sponsor assumes accountability for actions delegated to other individuals (e.g., 
Contract Research Organizations).

Study monitors will perform ongoing source data verification to confirm that data 
entered into the CRF by authorized site personnel are accurate, complete, and 
verifiable from source documents; that the safety and rights of participants are being 
protected; and that the study is being conducted in accordance with the currently 
approved protocol and any other study agreements, ICH GCP, and all applicable 
regulatory requirements. 

Records and documents, including signed ICFs, pertaining to the conduct of this study 
must be retained by the investigator for 15years after study completion unless local 
regulations or institutional policies require a longer retention period. No records may 
be destroyed during the retention period without the written approval of the sponsor. 
No records may be transferred to another location or party without written notification 
to the sponsor. 

If the participant withdraw consent for disclosure of future information, the sponsor 
may retain and continue to use any data collected before such a withdrawal of consent.
10.1.7.1
Data Recording
The data collection tool for this study will be a validated electronic data capture system called 
RAVE. Participant data necessary for analysis and reporting will be entered/transmitted into a 
validated database or data system (LSH).

CONFIDENTIAL
Clinical Study Protocol

Version 1.0                                                                      Page:  59 of 78
Data required according to this protocol will be recorded by study site personnel via data 
entry into the internet based EDC software system RAVE, which Bayer has licensed from 
Medidata Solutions Worldwide. RAVE has been validated by Medidata Solutions Worldwide 
and Bayer for use in its clinical studies. RAVE allows for the application of software logic to 
set-up data entry screens and data checks to ensure the completeness and accuracy of the data 
entered by the site personnel. Bayer extensively applies the logic to ensure data are complete 
and reflect the clinical data requirements of the study. Data queries resulting from the 
application of the software logic are resolved by the site personnel. The data are stored at a 
secure host facility maintained by Medidata Solutions Worldwide and transferred on a 
periodic basis to Bayer's internal computer system via a secure Virtual Private Network.
All access to the RAVE system is through a password-protected security system that is part of 
the RAVE software. All internal Bayer and external investigator site personnel seeking access 
must go through a thorough RAVE training process before they are granted access to RAVE 
for use in Bayer's clinical studies. Training records are maintained.
All personnel with access to the RAVE system are supported by a Service Desk staffed with 
trained personnel to answer questions and ensure access is maintained such that data entry can 
proceed in a timely manner.
The RAVE System contains a system-generated audit trail that captures any changes made to 
a data field, including who made the change, why the change was made and the date and time 
it was made. This information is available both at the investigator’s site and at Bayer. Data 
entries made in the RAVE EDC screens are supported by source documents maintained for all 
participants enrolled in this study.
Data recorded from screening failures
At minimum, the following data should be recorded in the CRF:

Demographic information (participant number; year of birth / age; sex; if applicable 
race / ethnicity)

Date of informed consent

Relevant inclusion/exclusion criteria

Reason for premature discontinuation

Date of last visit.
These data will be transferred to the respective database.
10.1.7.2
Monitoring
In accordance with applicable regulations, ICH-GCP, and sponsor’s/CRO’s procedures, 
monitors will contact the site prior to the start of the study to review with the site staff the 
protocol, study requirements, and their responsibilities to satisfy regulatory, ethical, and 
sponsor’s requirements. When reviewing data collection procedures, the discussion will also 
include identification and documentation of source data items.

The sponsor/designee will monitor the site activity to verify that the:

Data are authentic, accurate and complete.
Supporting data may be requested (example: blood glucose readings to support a 
diagnosis of diabetes). 

Safety and rights of participants are being protected

Study is conducted in accordance with the currently approved protocol
(including study treatment being used in accordance with the protocol)

Any other study agreements, ICH-GCP, and all applicable regulatory requirements are 
met.
The investigator and the head of the medical institution (where applicable) agrees to allow the 
monitor direct access to all relevant documents.
10.1.7.3
Data processing
Data will be collected as described in Section 10.1.7.1. Clinical data management will be 
performed in accordance with applicable sponsor’s/CRO’s standards and data cleaning 
procedures. This is applicable for data recorded on eCRF as well as for data from other 
sources (e.g. IxRS, laboratory, adjudication committees).
For data coding (e.g. AEs, medication), internationally recognized and accepted dictionaries 
will be used.
After its initial release for biometrical analysis, additional data release for analysis is possible, 
to include, for example, the following data: pharmacokinetic data, pharmacodynamic data, 
anti-drug antibody data etc.
10.1.7.4
Missing data
All efforts will be made to collect complete data for all participants randomized in this study. 
Participants will be followed up to the study end and all required data will be collected, 
regardless of participants’ compliance with study drug use or the visit schedule. 
Data from participants who prematurely terminate the study will be used to the maximum 
extent possible. All missing or partial data will be presented in the participant data listing as 
they are recorded in the eCRF. Data are collected primarily through an EDC system, which 
allows ongoing data entry and monitoring.
10.1.7.5
Audit and inspection
To ensure compliance with ICH-GCP and regulatory requirements, a member of the sponsor’s 
(or a designated CRO’s) quality assurance unit may arrange to conduct an audit to assess the 
performance of the study at the study site and of the study documents originating there. The 
investigator/institution will be informed of the audit outcome.
In addition, inspections by regulatory health authority representatives and IEC(s)/IRB(s) are 
possible. The investigator should notify the sponsor immediately of any such inspection.
The investigator/institution agrees to allow the auditor or inspector direct access to all relevant 
documents and allocate his/her time and the time of his/her staff to the auditor/inspector to

discuss findings and any issues. Audits and inspections may occur at any time during or after 
completion of the study.
10.1.7.6
Archiving
Essential documents shall be archived safely and securely in such a way that ensures that they 
are readily available upon authorities’ request.
Participant (hospital) files will be archived according to local regulations and in accordance 
with the maximum period of time permitted by the hospital, institution or private practice. 
Where the archiving procedures do not meet the minimum timelines required by the sponsor, 
alternative arrangements must be made to ensure the availability of the source documents for 
the required period.
The investigator/institution notifies the sponsor if the archival arrangements change 
(e.g. relocation or transfer of ownership).
The investigator site file is not to be destroyed without the sponsor’s approval.
The contract with the investigator/institution will contain all regulations relevant for the study 
site.
10.1.8
Source Documents

Source documents provide evidence for the existence of the participant and 
substantiate the integrity of the data collected. Source documents are filed at the 
investigator’s site.

Data reported on the CRF or entered in the eCRF that are transcribed from source 
documents must be consistent with the source documents or the discrepancies must be 
explained. The investigator may need to request previous medical records or transfer 
records, depending on the study. Also, current medical records must be available.

Definition of what constitutes source data can be found in the source data 
identification checklist

The site must implement processes to ensure availability of all required source 
documentation (e.g. participant file, local laboratory report, etc.). A source document 
checklist (not part of this protocol) will be used at the site to identify the source data 
for key data points collected and the monitor will work with the site to complete this.

Race and ethnic group may be entered directly into the CRF, without availability of 
corresponding source documentation. Thus, these CRF data will be the source and no 
additional source documentation will be available. For all other data, source 
documentation must be available at the site.
10.1.9
Study and Site Start and Closure
The sponsor designee reserves the right to close the study site or terminate the study at any 
time for any reason at the sole discretion of the sponsor. Study sites will be closed upon study 
completion. A study site is considered closed when all required documents and study supplies 
have been collected and a study-site closure visit has been performed.

The investigator may initiate study-site closure at any time, provided there is reasonable cause 
and sufficient notice is given in advance of the intended termination.
Reasons for the early closure of a study site by the sponsor or investigator may include but are 
not limited to:

Failure of the investigator to comply with the protocol, the requirements of the 
IRB/IEC or local health authorities, the sponsor's procedures, or GCP guidelines

Inadequate recruitment of participants by the investigator

Discontinuation of further study intervention development
If the study is prematurely terminated or suspended, the sponsor shall promptly inform the 
Investigators, the IECs/IRBs, the regulatory authorities, and any contract research 
organization(s) used in the study of the reason for termination or suspension, as specified by 
the applicable regulatory requirements. The Investigator shall promptly inform the participant
and should assure appropriate participant therapy and/or follow-up.
10.1.10
Publication Policy

The results of this study may be published or presented at scientific meetings. If this is 
foreseen, the investigator agrees to submit all manuscripts or abstracts to the sponsor 
before submission. This allows the sponsor to protect proprietary information and to 
provide comments. 

The sponsor will comply with the requirements for publication of study results. In 
accordance with standard editorial and ethical practice, the sponsor will generally 
support publication of multicenter studies only in their entirety and not as individual 
site data. In this case, a coordinating investigator will be designated by mutual 
agreement.


Appendix 3: Adverse Events: Definitions and Procedures for Recording, 
Evaluating, Follow-up, and Reporting
10.3.1
Definition of AE 
AE Definition

An AE is any untoward medical occurrence in a patient or clinical study participant, 
associated with the use of study intervention, whether or not considered related to 
the study intervention.

NOTE: An AE can therefore be any unfavorable and unintended sign (including an 
abnormal laboratory finding), symptom, or disease (new or exacerbated) associated 
with the use of study intervention.
Events Meeting the AE Definition 

Any abnormal laboratory test results (hematology, clinical chemistry, or urinalysis) 
or other safety assessments (eg, ECG, radiological scans, vital signs measurements), 
including those that worsen from baseline, considered clinically significant in the 
medical and scientific judgment of the investigator.

Exacerbation of a chronic or intermittent pre-existing condition including either an 
increase in frequency and/or intensity of the condition.

New conditions detected or diagnosed after study intervention administration even 
though it may have been present before the start of the study.

Signs, symptoms, or the clinical sequelae of a suspected drug-drug interaction.

Signs, symptoms, or the clinical sequelae of a suspected overdose of either study 
intervention or a concomitant medication. Overdose per se will not be reported as an 
AE/SAE unless it is an intentional overdose taken with possible suicidal/self-
harming intent. Such overdoses should be reported regardless of sequelae.

The signs, symptoms, and/or clinical sequelae resulting from lack of efficacy will be 
reported as AE or SAE if they fulfil the definition of an AE or SAE. Also, “lack of 
efficacy” or “failure of expected pharmacological action” also constitutes an AE or 
SAE.

Events NOT Meeting the AE Definition 

Any clinically significant abnormal laboratory findings or other abnormal safety 
assessments which are associated with the underlying disease, unless judged by the 
investigator to be more severe than expected for the participant’s condition.

The disease/disorder being studied or expected progression, signs, or symptoms of 
the disease/disorder being studied, unless more severe than expected for the 
participant’s condition.

Medical or surgical procedure (eg, endoscopy, appendectomy): the condition that 
leads to the procedure is the AE.

Situations in which an untoward medical occurrence did not occur (social and/or 
convenience admission to a hospital).

Anticipated day-to-day fluctuations of pre-existing disease(s) or condition(s) present 
or detected at the start of the study that do not worsen.
10.3.2
Definition of SAE
If an event is not an AE per definition above, then it cannot be an SAE even if serious 
conditions are met (e.g., hospitalization for signs/symptoms of the disease under study, death 
due to progression of disease).
An SAE is defined as any untoward medical occurrence that, at any dose:
a.
Results in death
b.
Is life-threatening

The term 'life-threatening' in the definition of 'serious' refers to an event in which the 
participant was at risk of death at the time of the event. It does not refer to an event, 
which hypothetically might have caused death, if it were more severe.
c.
Requires inpatient hospitalization or prolongation of existing hospitalization

In general, hospitalization signifies that the participant has been detained (usually 
involving at least an overnight stay) at the hospital or emergency ward for 
observation and/or treatment that would not have been appropriate in the physician’s 
office or outpatient setting. Complications that occur during hospitalization are AEs. 
If a complication prolongs hospitalization or fulfills any other serious criteria, the 
event is serious. When in doubt as to whether “hospitalization” occurred or was 
necessary, the AE should be considered serious.

Hospitalization for elective treatment of a pre-existing condition that did not worsen 
from baseline is not considered an AE.
d.
Results in persistent disability/incapacity

The term disability means a substantial disruption of a person’s ability to conduct

normal life functions.

This definition is not intended to include experiences of relatively minor medical 
significance such as uncomplicated headache, nausea, vomiting, diarrhea, influenza, 
and accidental trauma (eg, sprained ankle) which may interfere with or prevent 
everyday life functions but do not constitute a substantial disruption.

f.
Other situations:

Medical or scientific judgment should be exercised in deciding whether SAE 
reporting is appropriate in other situations such as important medical events that 
may not be immediately life-threatening or result in death or hospitalization but may 
jeopardize the participant or may require medical or surgical intervention to prevent 
one of the other outcomes listed in the above definition. These events should usually 
be considered serious.

Examples of such events include invasive or malignant cancers, intensive treatment 
in an emergency room or at home for allergic bronchospasm, blood dyscrasias or 
convulsions that do not result in hospitalization, or development of drug dependency 
or drug abuse.
10.3.3
Recording and Follow-Up of AE and/or SAE 
AE and SAE Recording

When an AE/SAE occurs, it is the responsibility of the investigator to review all 
documentation (e.g., hospital progress notes, laboratory reports, and diagnostics 
reports) related to the event.

The investigator will then record all relevant AE/SAE information in the CRF.

It is not acceptable for the investigator to send photocopies of the participant’s 
medical records to the sponsor in lieu of completion of the AE/SAE CRF page.

There may be instances when copies of medical records for certain cases are 
requested by the sponsor. In this case, all participant identifiers, with the exception 
of the participant number, will be redacted on the copies of the medical records 
before submission to the sponsor.

The investigator will attempt to establish a diagnosis of the event based on signs, 
symptoms, and/or other clinical information. Whenever possible, the diagnosis (not 
the individual signs/symptoms) will be documented as the AE/SAE.
Assessment of Intensity

The investigator will make an assessment of intensity for each AE and SAE reported 
during the study and assign it to 1 of the following categories: 

Mild: An event that is easily tolerated by the participant, causing minimal

discomfort and not interfering with everyday activities.

Moderate: An event that causes sufficient discomfort and interferes with normal 
everyday activities.

Severe: An event that prevents normal everyday activities. An AE that is 
assessed as severe should not be confused with an SAE. Severe is a category 
utilized for rating the intensity of an event; and both AEs and SAEs can be 
assessed as severe.

An event is defined as ‘serious’ when it meets at least 1 of the predefined outcomes 
as described in the definition of an SAE, NOT when it is rated as severe.
Assessment of Causality

The investigator is obligated to assess the relationship between study intervention 
and each occurrence of each AE/SAE.

A “reasonable possibility” of a relationship conveys that there are facts, evidence, 
and/or arguments to suggest a causal relationship, rather than a relationship cannot 
be ruled out.

The investigator will use clinical judgment to determine the relationship.

Alternative causes, such as underlying disease(s), concomitant therapy, and other 
risk factors, as well as the temporal relationship of the event to study intervention 
administration will be considered and investigated.

The investigator will also consult the Investigator’s Brochure (IB) and/or Product 
Information, for marketed products, in his/her assessment.

For each AE/SAE, the investigator must document in the medical notes that he/she 
has reviewed the AE/SAE and has provided an assessment of causality.

There may be situations in which an SAE has occurred and the investigator has 
minimal information to include in the initial report to the sponsor. However, it is 
very important that the investigator always make an assessment of causality for 
every event before the initial transmission of the SAE data to [the sponsor.

The investigator may change his/her opinion of causality in light of follow-up 
information and send an SAE follow-up report with the updated causality 
assessment.

The causality assessment is one of the criteria used when determining regulatory 
reporting requirements.
Follow-up of AEs and SAEs

The investigator is obligated to perform or arrange for the conduct of supplemental 
measurements and/or evaluations as medically indicated or as requested by the 
sponsor to elucidate the nature and/or causality of the AE or SAE as fully as 
possible. This may include additional laboratory tests or investigations,

histopathological examinations, or consultation with other health care professionals.

If a participant dies during participation in the study or during a recognized follow-
up period, the investigator will provide 
 with a copy 
of any post mortem findings including histopathology.

New or updated information will be recorded in the originally completed CRF.

The investigator will submit any updated SAE data to the [sponsor] within 24 hours 
of receipt of the information.
10.3.4
Reporting of SAEs
SAE Reporting to the sponsor via an Electronic Data Collection Tool

The primary mechanism for reporting an SAE to the sponsor will be the electronic 
data collection tool.

If the electronic system is unavailable, then the site will use the paper SAE data 
collection tool (see next section) in order to report the event within 24 hours

The site will enter the SAE data into the electronic system as soon as it becomes 
available.

After the study is completed at a given site, the electronic data collection tool will be 
taken off-line to prevent the entry of new data or changes to existing data.

If a site receives a report of a new SAE from a study participant or receives updated 
data on a previously reported SAE after the electronic data collection tool has been 
taken off-line, then the site can report this information on a paper SAE form and 
transmit to 
 

Contacts for SAE reporting can be found in the Investigator Site File.
SAE Reporting to the sponsor via Paper CRF

Facsimile transmission of the SAE paper CRF is the preferred method to transmit 
this information to the Sponsor via 

In rare circumstances and in the absence of facsimile equipment, notification by 
telephone is acceptable with a copy of the SAE data collection tool sent by overnight 
mail or courier service.

Initial notification via telephone does not replace the need for the investigator to 
complete and sign the SAE CRF pages within the designated reporting time frames.

Contacts for SAE reporting can be found in the Investigator Site File.

10.3.5
Outcome Event Reporting Process Overview
If an AE or SAE is a potential outcome event (all bleeding, death, MI, stroke, TIA and stent 
thrombosis [Section 8.3.6]), it must be collected and reported on the dedicated forms on an 
ongoing basis, until the participant has completed the study. Thus, even if a participant is no 
longer taking study medication this would be until the end of the regular, planned end of 
treatment for this participant (i.e. until the participant’s last visit. After completion of safety 
follow-up visit, for participants that prematurely discontinued study intervention, there is no 
further requirement for reporting AEs. Only potential outcome events are to be reported (refer 
to section 8.3.1 and 10.8).
10.4
Appendix 4: Contraceptive Guidance and Collection of Pregnancy 
Information
Definitions:
Woman of Childbearing Potential (WOCBP)
A woman is considered fertile following menarche and until becoming post-menopausal 
unless permanently sterile (see below).
If fertility is unclear (eg, amenorrhea in adolescents or athletes) and a menstrual cycle cannot 
be confirmed before first dose of study intervention, additional evaluation should be 
considered.
Women in the following categories are not considered WOCBP
1.
Premenarchal
2.
Premenopausal female with 1 of the following:

Documented hysterectomy

Documented bilateral salpingectomy

Documented bilateral oophorectomy
For individuals with permanent infertility due to an alternate medical cause other than the 
above, (eg, Müllerian agenesis, androgen insensitivity), investigator discretion should be 
applied to determining study entry.
Note: Documentation can come from the site personnel’s: review of the participant’s medical 
records, medical examination, or medical history interview.
Postmenopausal Female

A postmenopausal state is defined as no menses for 12 months without an alternative 
medical cause. 

A high follicle stimulating hormone (FSH) level in the postmenopausal range may be 
used to confirm a postmenopausal state in women not using hormonal contraception or 
hormonal replacement therapy (HRT). However, in the absence of 12 months of 
amenorrhea, confirmation with more than one FSH measurement (>40 IU/L) is 
required.


Females on HRT and whose menopausal status is in doubt will be required to use one 
of the non-estrogen hormonal highly effective contraception methods if they wish to 
continue their HRT during the study. Otherwise, they must discontinue HRT to allow 
confirmation of postmenopausal status before study enrollment.
Contraception Guidance:

Female participants must be of non-child bearing potential as per Clinical Trial 
Facilitation Group (CTFG) guidelines.

Male participants must agree to use condoms when sexually active with a woman of 
childbearing potential from the time of the first dose to 7 days after the last dose of 
study intervention. This is in line with the CTFG guideline, as BAY 2433334 is non 
genotoxic but data related to teratogenicity/fetotoxicity in early pregnancy (Segment 2 
studies) are not available at this stage of development. In addition, all men must not 
donate sperm during the study.
Male Participants with Partners Who Become Pregnant 

The investigator will attempt to collect pregnancy information on any male 
participant’s female partner who becomes pregnant while the male participant is in 
this study. This applies only to male participants who receive study intervention.

After obtaining the necessary signed informed consent from the pregnant female 
partner directly, the investigator will record pregnancy information on the appropriate 
form and submit it to the sponsor within 24 hours of learning of the partner’s 
pregnancy. The female partner will also be followed to determine the outcome of the 
pregnancy. Information on the status of the mother and child will be forwarded to the 
sponsor. Generally, the follow-up will be no longer than 6 to 8 weeks following the 
estimated delivery date. Any termination of the pregnancy will be reported regardless 
of fetal status (presence or absence of anomalies) or indication for the procedure.
Female participants Who Become Pregnant 

The investigator will collect pregnancy information on any female participant who 
becomes pregnant while participating in this study. Information will be recorded on 
the appropriate form and submitted to the sponsor within 24 hours of learning of a 
participant's pregnancy. 

The participant will be followed to determine the outcome of the pregnancy. The 
investigator will collect follow-up information on the participant and the neonate, after 
obtaining the signed informed consent from both parents, unless local law or specific 
circumstances of the respective case allow otherwise, and the information will be 
forwarded to the sponsor. Generally, follow-up will not be required for longer than 6 
to 8 weeks beyond the estimated delivery date. Any termination of pregnancy will be 
reported, regardless of fetal status (presence or absence of anomalies) or indication for 
the procedure.

While pregnancy itself is not considered to be an AE or SAE, any pregnancy 
complication or elective termination of a pregnancy will be reported for medical 
reasons will be reported as an AE or SAE.


A spontaneous abortion (occurring at < 22 weeks gestational age) or still birth
(occurring at >22 weeks gestional age) is always considered to be an SAE and will be 
reported as such. 

Any post-study pregnancy related SAE considered reasonably related to the study 
intervention by the investigator will be reported to the sponsor as described in Section 
8.3.4. While the investigator is not obligated to actively seek this information in 
former study participants, he or she may learn of an SAE through spontaneous 
reporting. 

Any female participant who becomes pregnant while participating in the study will be 
withdrawn from the study.
10.5
Appendix 5: Liver Safety: Suggested Actions and Follow-up Assessments 
Any participant with an ALT or AST > 3 x ULN must be re-tested as soon as possible but at 
the latest within 48-72 hours of the investigator becoming aware of the result. This re-testing 
and any subsequent testing based on elevated levels should include measurement of ALT, 
AST, total and direct bilirubin,  AP and INR, and will be assessed by local laboratory. There 
also should be inquiry made about symptoms.
Every effort should be made to clarify the etiology of elevated levels and lab testing may 
include, but not be limited to, testing for viral hepatitis, cytomegalovirus, Epstein-Barr virus, 
human immunodeficiency virus (once the participant has provided written consent), testing of 
ferritin levels, iron, iron binding capacity, antinuclear antibody, and smooth muscle 
antibodies. Patient management is at the discretion of the treating physician but the 
investigator  may continue the study drug during retesting.
Liver function test monitoring should be performed as above for all participants with elevated 
ALT or AST >3 ULN even if the study drug is interrupted until tested values have 
normalized or returned to patient’s baseline. If close liver monitoring is not possible then the 
patient should discontinue study medication.
For ALT or AST > 3 x ULN concurrent with a total bilirubin > 2 x ULN, every effort should 
be made to promptly clarify any possible underlying disease(s).
The frequency of liver function tests based on re-test values is shown in Table 10–2.

Appendix 7: Calculating glomerular filtration rate
In accordance with established nephrology practice and guidelines, renal function at baseline 
and throughout the study will be assessed by means of the estimated glomerular filtration rate 
(eGFR), calculated using the Modification of Diet in Renal Disease (MDRD) study 
abbreviated formula.
Isotope dilution mass spectroscopy (IDMS)-traceable MDRD Study Equation:
Conventional units (serum creatinine level is measured in mg/dL)
GFR (mL/min/1.73 m2) = 175 x (serum creatinine)-1.154 x (Age)-0.203 x (0.742 if female) x 
(1.212 if African American)
GFR can be estimated using the calculator provided in the following link:

Appendix 8: Outcome Events: Data Collection
All outcome events (efficacy and safety) are to be captured and reported from randomization 
until participant´s regular last scheduled study visits (ie, Safety Follow-up Visit; in case of 
permanent discontinuation of study intervention, the planned regular EoT visit). The eCRF
will contain specific Outcome Event pages, as well as AEs subpages to capture the outcome 
events occurring throughout the study. The following points need to be considered when 
reporting outcome events.

Outcomes events occurring after randomization and before the first intake of the study
intervention: the outcome event will be considered part of the medical history and should 
be reported in the outcome event eCRF page 

Outcomes events occurring after randomization and after first intake of study 
intervention and up to the SFU visit: the outcome event will be considered both AE and 
outcome event and should be reported in both in the AE page and in the AE’s subpage for 
outcome events.

Outcome events occurring after SFU visit through the end of the study (for participant 
who discontinue study intervention): the outcome events should be collected until 
completion of participant´s regular scheduled study visits and should be reported in the 
outcome event eCRF page.
