SYNOPSIS
STUDY TITLE
A 
Prospective, 
Open-Label, 
Active-Controlled 
Study 
to 
Evaluate 
the 
Pharmacokinetics, 
Pharmacodynamics, Safety, and Efficacy of Rivaroxaban for Thromboprophylaxis in Pediatric Subjects 2 
to 8 Years of Age after the Fontan Procedure
DESCRIPTION OF THE COMPOUND
Rivaroxaban is an oral, highly selective direct Factor Xa (FXa) inhibitor.  Inhibition of FXa interrupts the 
intrinsic and extrinsic pathway of the blood coagulation cascade, inhibiting both thrombin formation and 
development of thrombi. The clinical development program for rivaroxaban is extensive, covering the 
prevention and treatment of multiple thrombosis-mediated conditions. Rivaroxaban is marketed under the 
trade name XARELTO® and has been approved for multiple adult indications worldwide. As of 
September 2015, more than 60, 000 subjects have been treated with rivaroxaban in clinical trials (Phase 1 
through Phase 4), covering several indications, including the prophylaxis of venous thromboembolism 
(VTE) in adults undergoing elective hip or knee replacement surgery, the treatment of deep vein 
thrombosis (DVT) and/or pulmonary embolism (PE) and the reduction in the risk of recurrence of DVT 
and PE, and to reduce the risk of stroke and systemic embolism in non-valvular atrial fibrillation (NVAF).
XARELTO is also approved in the European Union (EU) for the prevention of atherothrombotic events 
(cardiovascular death, myocardial infarction, or stroke) after an acute coronary syndrome in adults with 
elevated cardiac biomarkers.
OBJECTIVES AND HYPOTHESIS
Primary Objectives
Part A
To characterize the single- and multiple-dose pharmacokinetics (PK) and PK/pharmacodynamics (PD) 
profiles after oral rivaroxaban therapy administered to pediatric subjects 2 to 8 years of age with single 
ventricle physiology who have completed the Fontan procedure within 4 months prior to enrollment.
Part B
To evaluate the safety and efficacy of rivaroxaban, administered twice daily (exposure matched to 
rivaroxaban 10 mg once daily in adults) compared to acetylsalicylic acid (ASA), given once daily 
(approximately 5 mg/kg) for thromboprophylaxis in pediatric subjects 2 to 8 years of age with single 
ventricle physiology who have completed the Fontan procedure within 4 months prior to enrollment.
Secondary Objectives
Part A
To assess the safety and tolerability of rivaroxaban treatment.
Part B
To further characterize the PK and PK/PD profiles of rivaroxaban.

Clinical Protocol 39039039CHD3001 - Amendment INT-2

Approved, Date: 27 July 2017
Hypothesis
Children with congenital heart disease (CHD) who underwent the Fontan procedure will respond to FXa 
inhibition by rivaroxaban in a similar manner as seen in adults. This hypothesis is supported by ex vivo 
spiking experiments, which covered the entire rivaroxaban concentration in clinical studies ranging up to 
500 ng/mL, and in which similar exposure-response relationships existed in healthy children and adults of 
different age groups (23 days to 23 months, 2 to 6 years, 7 to 11 years, 12 to 16 years, and adults).1,2
No statistical hypothesis testing is planned for this study.
OVERVIEW OF STUDY DESIGN
This is a prospective, open-label, active-controlled, multicenter study designed to evaluate the PK and 
PK/PD profiles, safety, and efficacy of rivaroxaban for thromboprophylaxis in pediatric subjects 2 to 
8 years of age with single ventricle physiology who have completed the Fontan procedure within 
4 months prior to enrollment.
This study consists of 2 parts:

Part A: This is the 12-month, non-randomized, open-label part of the study, which includes a 12-day 
Initial PK, PD, and Safety Assessment Period. An internal Data Review Committee (DRC) will 
assess by Day 12 the single- and multiple-dose rivaroxaban PK, PD, and the initial safety and 
tolerability data available from each subject, prior to the subject continuing in the study to complete 
the planned 12 months of open-label rivaroxaban therapy of Part A. Subjects in Part A will not 
participate in Part B.
Randomization in Part B of this study will begin once the cumulative data from the Initial PK, PD,
and Safety Assessment Period in Part A are deemed acceptable by the Independent Data Monitoring 
Committee (IDMC).

Part B: This is the randomized, open-label, active-controlled part of the study that will evaluate the 
safety and efficacy of rivaroxaban compared to ASA for thromboprophylaxis for 12 months. 
Subjects randomized to rivaroxaban will also have PK and PD assessments.
Subjects Participating in Part A 
Part A of the study will consist of an up to 21-day Screening Period, a 12-day Initial PK, PD, and Safety 
Assessment Period, a 12-month Open-Label Treatment Period, and a 30-day Follow-Up Contact 
(phone contact). Approximately 10 pediatric subjects are planned to be enrolled in Part A.
Parental informed consent/child assent (as appropriate, typically at age ≥7 years or as defined by local 
regulations) must be obtained prior to performing any study-specific procedures. The screening 
assessments will take place after the Fontan procedure and up to 21 days before the first dose of 
rivaroxaban. During the screening period, baseline laboratory blood testing will be done and a 
transthoracic echocardiogram will be performed to rule out thrombosis. Laboratory parameters obtained 
as part of the post-surgery standard-of-care may be used for screening if they have been done within 
21 days prior to receiving the first dose of rivaroxaban. The most recent post-Fontan clinical laboratory 
results will be used for screening if there are multiple laboratory results. Subjects who do not meet all of 
the enrollment criteria for the study may be rescreened 1 additional time as long as enrollment is within 
4 months of their Fontan procedure. Subjects who are rescreened will be assigned a new subject number, 
undergo the informed consent process, and then restart a new screening phase.

Approved, Date: 27 July 2017
Subjects who meet all of the inclusion and none of the exclusion criteria will be enrolled and will receive 
the first dose of rivaroxaban oral suspension on Day 1 (on site). Rivaroxaban will be given twice daily for 
12 days (+9 days). Pharmacokinetic and PD samples will be collected on Day 1 and Day 4 (+2 days) of 
rivaroxaban administration. An internal DRC will assess before the subject returns for Day 12 the PK, 
PD, and the safety data available from each subject, prior to the subject continuing in the study to 
complete the planned 12 months of open-label rivaroxaban therapy. The subjects who are allowed to 
continue the 12-month treatment will also have PK and PD samples collected at Month 3 and Month 12. 
Safety and efficacy will be evaluated throughout the study. The assessment criteria will be described in 
the DRC charter.
Randomization in Part B of this study will begin once the cumulative data from the Initial PK, PD, and 
Safety Assessment Period in Part A are deemed acceptable by the IDMC. The decision tree of
rivaroxaban exposure acceptability criteria will be described in the IDMC charter.
Subjects Participating in Part B
For subjects randomized into Part B, there will be an up to 21-day Screening Period, a 12-month 
Open-Label Treatment Period, and a 30-day Follow-Up Contact (phone contact). Approximately 
90 subjects who meet all the inclusion and none of the exclusion criteria will be randomly assigned in a 
2:1 ratio to receive rivaroxaban oral suspension and ASA for 12 months.
Parental informed consent/child assent (as appropriate, typically at age ≥7 years or as defined by local 
regulations) must be obtained prior to performing any study-specific procedures. Subjects will undergo 
the same screening evaluations as in Part A. Eligible subjects will be enrolled and randomized on Day 1 
and will receive their first dose of study drug on site at this visit. Subjects may be enrolled and 
randomized on the business day prior to Day 1 to facilitate logistics, provided the investigator ensures that 
the subject meets all eligibility criteria prior to randomization. Pharmacokinetic and PD samples will be 
obtained on Day 1, Month 3, and Month 12 for subjects randomized to rivaroxaban only. Safety and 
efficacy will be evaluated throughout the study for all subjects.
Early Study Medication Discontinuation
For subjects in Part A and Part B who prematurely discontinue study drug for any reason, the Early Study 
Medication Discontinuation (ESMD) visit will be performed as soon as possible after discontinuation. A 
Follow-Up Contact (phone contact) will be performed 30 days following the last dose of study drug and 
at Month 12, the end of the planned treatment period.
Note: An exception are subjects who are enrolled after local reading of the Screening transthoracic 
echocardiogram rules out thrombosis, and subsequently reported to have thrombosis after central reading 
by the core laboratory of the same transthoracic echocardiogram. These subjects will be withdrawn from 
the study when the result of the echocardiogram by the core laboratory becomes available. Subjects will 
be asked to return for the ESMD visit as soon as possible. They will not be required to have a repeat 
transthoracic echocardiogram as part of the ESMD. Subjects will go on to receive proper care according 
to the healthcare provider’s judgment. They will be contacted by phone approximately 30 days (+/-
7 days) after last dose of study drug (Follow-Up Contact). An ESMD Month 12 follow up visit will not be 
required.
Committees
An Executive Committee (EC), an internal DRC, IDMC, Central Independent Adjudication Committee 
(CIAC), Steering Committee (SC), and a Sponsor Committee will be commissioned for this study.

DOSAGE AND ADMINISTRATION
Rivaroxaban: The rivaroxaban dose to be used in this study was determined via an adapted 
Physiologically-based Pharmacokinetics (PBPK) modeling approach. Rivaroxaban will be administered 
twice daily in an open-label fashion as a 0.1% (1 mg/ml) oral suspension with target exposure (area under 
the plasma concentration time curve from 0 to 24 hours [AUC0-24]) at steady state matching to that of 
rivaroxaban 10 mg total daily dose in adults (age- and body weight-adjusted dosing). Because children 
with an estimated glomerular filtration rate below 30 mL/min/1.73 m2 are excluded from the study, dose 
reduction for impaired renal function is not required. Rivaroxaban will be taken in the morning and in the 
evening (approximately 12 hours apart) and at approximately the same times each day as described in the 
study booklet. Dose adjustment, due to increased body weight, will be made at Month 6 (both Part A and 
Part B).
ASA: Acetylsalicylic acid will be provided as 81-mg or 100-mg tablets according to local practice. 
Subjects randomized to ASA will receive approximately 5 mg/kg of ASA to a maximum of 1 whole tablet 
as a single daily dose as described in the study booklet. Tablets can be split in half, if necessary (eg,
children weighing ≤10 kg), to meet the daily dose, and the dose must be documented. It is recommended 
that tablets are not split more than in half. Dose adjustments due to increased body weight will be made at 
Month 6 as appropriate.
Temporary discontinuation of study drug is allowed for events, such as intercurrent illnesses. In this case, 
standard clinical practice should be followed.

SAFETY EVALUATIONS/OUTCOMES
The primary safety outcome will be major bleeding events, as defined below. Clinically relevant 
non-major bleeding events and trivial (minimal) bleeding will be secondary safety outcomes.
The safety and tolerability of rivaroxaban will also be evaluated by assessing adverse events and clinical 
laboratory values. 
Bleeding events will be adjudicated by the CIAC using the International Society on Thrombosis and 
Hemostasis (ISTH) recommendations.
Major bleeding is defined as overt bleeding and:

Associated with a fall in hemoglobin of 2 g/dL or more; or

Leading to a transfusion of the equivalent of 2 or more units of packed red blood cells or whole 
blood in adults; or

Occurring in a critical site: intracranial, intraspinal, intraocular, pericardial, intra-articular, 
intramuscular with compartment syndrome, retroperitoneal; or

Contributing to death.
Clinically relevant non-major bleeding is defined as overt bleeding not meeting the criteria for major 
bleeding but associated with:

Medical intervention, or

Unscheduled contact (visit or telephone call) with a physician, or

(Temporary) cessation of study treatment, or 

Discomfort for the subject such as pain, or 

Impairment of activities of daily life (such as loss of school days or hospitalization).
Trivial (minimal) bleeding is defined as any other overt bleeding event that does not meet criteria for 
clinically relevant non major bleeding.
EFFICACY EVALUATIONS/OUTCOMES
The primary efficacy outcome will be any thrombotic event (venous or arterial), defined as:

The appearance of a new thrombotic burden within the cardiovascular system on either routine 
surveillance or clinically indicated imaging, or

The occurrence of a clinical event known to be strongly associated with thrombus (such as 
cardioembolic stroke, pulmonary embolism).
Subjects who develop either a symptomatic or asymptomatic thrombotic event during the study must 
permanently discontinue the study drug. All available imaging results (eg, transthoracic or 
transesophageal echocardiograms, or MRIs), should be sent to the CIAC. After cessation of the study 
drug, it is at the investigator’s discretion to continue with other antithrombotic therapy. The investigator 
should document this therapy in the eCRF. Thrombotic events will not be reported as adverse events or 
serious adverse events, as they will be reported as efficacy outcomes.
Transthoracic echocardiograms will be centrally read by an echocardiographic core laboratory. All 
thrombotic events and the primary cause of any death will be adjudicated by the CIAC.

STATISTICAL METHODS
Sample Size Determination
A total of at least 100 pediatric subjects overall are planned to be enrolled in this study. The total sample 
size does not originate from a formal sample size calculation but is based on regulatory feedback to obtain 
sufficient safety data in this pediatric population. No statistical hypothesis will be tested in either part of 
this study.  
The sample size of approximately 10 subjects for Part A is considered adequate for the initial assessment 
of the rivaroxaban PK in the studied pediatric subjects and determine the dosing regimen to be studied in 
Part B. Approximately 90 subjects will be enrolled into Part B of the study.    
Pharmacokinetics, Pharmacodynamics, Safety, and Efficacy Analyses
No statistical hypothesis will be tested in Part A or Part B. 
Descriptive statistics will be used to summarize rivaroxaban PK data for each time interval. 
Pharmacodynamics measurements, including PT, aPTT, and anti-FXa activity will be plotted against 
rivaroxaban plasma concentrations and will also be summarized by timepoint.
Rivaroxaban PK parameters, including AUC0-24, maximum plasma concentration (Cmax) after single dose,
and AUC0-24, Cmax, and minimum plasma concentration (Cmin) at steady sate, will be derived by model-
based methods. Pharmacokinetics/PD relationship will be quantified. Results from PK and PK/PD 
analyses will be reported separately from the Clinical Study Report.
For both parts of the study, safety and efficacy (adverse events, bleedings, and thrombotic events) will be 
summarized.

INTRODUCTION
Rivaroxaban is an oral, highly selective direct Factor Xa (FXa) inhibitor. Inhibition of FXa
interrupts the intrinsic and extrinsic pathway of the blood coagulation cascade, inhibiting both 
thrombin formation and development of thrombi. The clinical development program for 
rivaroxaban is extensive, covering the prevention and treatment of multiple thrombosis-mediated 
conditions through a joint collaboration agreement between Bayer HealthCare AG and Ortho 
McNeil Pharmaceuticals, Inc (now Janssen Research and Development, LLC). Rivaroxaban has 
been approved in multiple indications worldwide under the trade name XARELTO®. As of 
September 2015, more than 60,000 subjects have been treated with rivaroxaban in clinical trials 
(Phase 1 through Phase 4), covering several indications, including the prophylaxis of venous 
thromboembolism (VTE) in adults undergoing elective hip or knee replacement surgery, the
treatment of deep vein thrombosis (DVT) and/or pulmonary embolism (PE) and the reduction in 
the risk of recurrence of DVT and PE, and to reduce the risk of stroke and systemic embolism in 
non-valvular atrial fibrillation XARELTO is also approved in the EU for the prevention of 
atherothrombotic events (cardiovascular death, myocardial infarction, or stroke) after an acute 
coronary syndrome in adults with elevated cardiac biomarkers. 
Rivaroxaban is currently being studied in pediatric subjects with VTE (see Section 1.1.4, 
Physiology-Based Pharmacokinetics). It has been well tolerated in a Phase 2 and Phase 3 study 
in pediatric subjects for the treatment and secondary prevention of VTE (studies ongoing).
For the most comprehensive nonclinical and clinical information regarding rivaroxaban, refer to 
the latest version of the Investigator's Brochure.14

Information page(s), which will be provided as a separate document.
1.1.
Background
1.1.1.
Pediatric Patients with Single Ventricle Physiology – The Fontan 
Procedure - Scope of the Problem 
The Fontan procedure has become the most common procedure performed for congenital heart 
disease (CHD) after the age of 2 years and is the final palliative surgery for children with single 
ventricle physiology.10,19 Improvements in early outcomes have led to an increase in the number 
of patients surviving into adulthood after this palliative procedure.15 In response to the need for 
population-based data, Fontan patient registries have been established in North America 
(Society of Thoracic Surgeons Congenital Heart Surgery Database, STS-CHSDB), Europe 
(EACTS Congenital Database) and Australia and New Zealand (Fontan Registry). Collectively, 
these registries reported about 1,460 Fontan procedures per year during 2007 to 2011, which 
captured the majority of the Fontan procedures performed in those regions.3,16,31
Thrombosis remains an important complication for patients with single ventricle physiology 
following the Fontan procedure; however, the true frequency of thrombotic events is not well 
known.21,22 Several studies have estimated that the prevalence of thrombosis events occurring 
post-Fontan procedure ranges from 17% to 33%, with a reported mortality of 25% due to an

associated post-Fontan thromboembolism.4,9,30 The risk of thrombotic complications is higher 
within 6 months after the Fontan procedure and the risk diminishes but persists over the first 
2.5 years thereafter.18
1.1.2.
Human Pharmacokinetics in Adults
Rivaroxaban is rapidly absorbed after oral administration, with peak plasma concentrations 
occurring approximately 2 to 4 hours postdose. Rivaroxaban is a low clearance drug (clearance is 
approximately 10 L/h or 0.14 L/h/kg) and does not undergo any relevant first-pass metabolism. 
The terminal elimination half-life of rivaroxaban ranges from 5 to 9 hours in healthy young male 
subjects and from 11 to 13 hours in healthy elderly subjects (aged 65 to 83 years). Due to the 
multiple elimination pathways of rivaroxaban, there are few clinically relevant drug-drug 
interactions. 
In drug-drug interaction studies evaluating the concomitant use with drugs that are combined 
P-glycoprotein (P-gp) and cytochrome P450 3A4 (CYP3A4) inhibitors, increases in rivaroxaban 
exposure were observed. Similar increases in pharmacodynamic effects (ie, FXa inhibition and 
prothrombin time [PT] prolongation) were also observed. Significant increases in rivaroxaban 
exposure may increase bleeding risk.
In a drug interaction study, coadministration of rivaroxaban (20-mg single dose with food) with a 
drug that is a combined P-gp and strong CYP3A4 inducer (rifampicin titrated up to 600 mg once 
daily) led to an approximate decrease of 50% and 22% in area under the plasma concentration 
curve (AUC) and maximum plasma concentration (Cmax), respectively. Similar decreases in PD 
effects were also observed. These decreases in exposure to rivaroxaban may decrease efficacy.
1.1.3.
Efficacy and Safety Profile Based on Adult Clinical Studies
The efficacy and safety of rivaroxaban have been studied in several large clinical development 
programs for the prevention and treatment of multiple thrombosis-mediated conditions. 
The highlights of relevant studies are:

The pooled analysis of 4 studies comprising the RECORD program involving 
12,729 subjects undergoing hip or knee arthroplasty demonstrated that rivaroxaban given at 
a dose of 10 mg once daily compared with enoxaparin given at a dose of 30 mg twice daily 
or 40 mg once daily for 30 days significantly reduced the risk of symptomatic VTE and 
mortality (0.8% absolute risk decrease). Rivaroxaban increased the risk of bleeding slightly 
compared with enoxaparin (0.2% absolute risk increase in major bleeding events).

The ROCKET AF study involving 14,264 patients with NVAF at high risk of stroke 
demonstrated that rivaroxaban 20 mg once daily (15 once daily in subjects with an estimated 
glomerular filtration rate of 30 to 49 ml/min) compared with warfarin (target international 
normalized ratio [INR] 2.0 to 3.0) for a mean of 19 months was non inferior for the 
prevention of stroke or systemic embolism (hazard ratio 0.88; 95% confidence interval: 0.74
to 1.03), with a significant reduction in life-threatening, intracranial and fatal bleeding and a 
favorable effect on mortality, but more transfusions and hemoglobin decreases of >2 gm/dl.

Clinical Protocol 39039039CHD3001 - Amendment INT-2
23
Approved, Date: 27 July 2017

The EINSTEIN VTE treatment studies involving 9,447 subjects with VTE demonstrated 
that rivaroxaban 15 mg twice daily for 3 weeks followed by 20 mg once daily compared 
with initial low molecular-weight heparin (LMWH) followed by warfarin (INR 2.0 to 3.0) 
was associated with a similar or reduced risk of recurrent VTE with a similar or reduced rate 
of major bleeding during up to 12 months. Overall bleeding rates were similar with 
rivaroxaban compared to enoxaparin/ vitamin K antagonists (VKA), and showed a clinically 
important reduction in major bleeding risk. 

Rivaroxaban has been studied for reduction of the risk of thrombotic cardiovascular (CV) 
events in patients with acute coronary syndrome (ACS) (ST segment elevation myocardial 
infarction, non-ST-segment elevation myocardial infarction, or unstable angina) in 
combination with acetylsalicylic acid (ASA) alone or with ASA plus a thienopyridine 
(clopidogrel or ticlopidine) in the ATLAS program. The ATLAS ACS 2 TIMI 51 study 
randomized a total of 15,526 subjects and demonstrated that rivaroxaban 2.5 mg or 5 mg 
twice daily compared with placebo reduced the risk of CV death, MI, or stroke by 16% in 
patients with a recent ACS, most of whom (92%) were also receiving dual antiplatelet 
therapy. The incidences of all categories of treatment-emergent bleeding were consistently 
higher in subjects treated with rivaroxaban compared with placebo. The higher rates of 
bleeding with rivaroxaban were expected, since in this study rivaroxaban was compared to 
placebo on the background of standard antiplatelet therapy.

The MAGELLaN study compared VTE prophylaxis with oral rivaroxaban 10 mg once daily 
for 35 days with enoxaparin 40 mg daily for 10 days in subjects who were hospitalized for a 
medical illness. The MAGELLaN study randomized 8,101 subjects and met both of its 
primary efficacy objectives (ie, for rivaroxaban versus enoxaparin/placebo noninferiority at 
Day 10, and superiority at Day 35). Although bleeding rates in MAGELLaN were low 
overall, the incidences of clinically relevant bleeding events were increased in rivaroxaban 
treated subjects compared to enoxaparin. 
In addition to bleeding, other adverse reactions associated with rivaroxaban include nausea, 
fever, kidney and liver impairment, dyspepsia, allergic reactions including skin reactions, 
itching, rash, hives, swelling of face, lips, mouth, tongue, skin or throat, and cholestasis.
Postmarketing data gathered subsequently to the pivotal studies do not change the favorable 
benefit-risk assessment of rivaroxaban in the approved indications. 
For the most comprehensive description of the safety profile of rivaroxaban, refer to the latest 
version of the Investigator's Brochure for rivaroxaban.14
1.1.4.
Physiology-Based Pharmacokinetics
The rivaroxaban doses that are being tested in the pediatric VTE treatment studies were derived 
using Physiologically-based Pharmacokinetics (PBPK) modeling (ie, extrapolation of the known 
pharmacokinetic (PK) properties of the drug into the pediatric population by way of physiology 
based translational approaches).6,7 The primary goal for dosing is to achieve in pediatric patients 
an equivalent exposure (as measured by AUC) to the 20 mg once daily dose regimen that has 
demonstrated effectiveness for treatment of VTE in adults. The term ‘equivalent exposure’ is 
used to indicate the achievement of a similar area under the plasma concentration curve from

Approved, Date: 27 July 2017
0 to 24 hours (AUC0-24) value between pediatric and adult subjects. For assessing dose linearity, 
pediatric doses that provide equivalent exposure to the rivaroxaban 10-mg once daily regimen in 
adults are also being evaluated in the Phase 1 study conducted by Bayer Healthcare. Based on 
the current knowledge of the coagulation system in the pediatric population, the expectation is 
that children will respond to FXa inhibition in a similar manner to adults. This hypothesis is 
supported by ex-vivo spiking experiments, which covered the entire rivaroxaban concentration in 
clinical studies ranging up to 500 ng/mL, and in which similar exposure-response relationships 
existed in healthy children and adults of different age groups (23 days to 23 months, 2 to 6 years, 
7 to 11 years, 12 to 16 years, and adults).1,2,25
1.1.5.
Efficacy and Safety Profile Based on Pediatric Clinical Studies 
Rivaroxaban is currently being developed for the treatment of VTE in pediatric subjects 
(EINSTEIN Junior program). The VTE treatment pediatric clinical development program was 
designed in a comprehensive, staggered and stepwise approach to establish pediatric age-specific 
dosing recommendations and to explore the comparative safety and efficacy of rivaroxaban to 
the standard-of-care therapy in children from birth to <18 years. As of 29 March 2016, 
223 pediatric subjects have received at least one dose of rivaroxaban in these pediatric trials. 
The VTE treatment program is comprised of 7 studies of which 1 study has been completed, 5 
are ongoing and 1 is planned to start in 2017.

Two Phase 1 studies: 

Study #12892 is a Phase 1 study in pediatric subjects from 6 months to 18 years of age, 
which recently completed enrollment. This Phase 1 study was designed to evaluate the 
safety profile of a single dose of rivaroxaban ready to use suspension and confirm the 
age- and body-weight adjusted pediatric dose recommendations equivalent to 10 and 
20 mg single dose in adults derived from adult data and PBPK modeling. 

Study #17992 is another Phase 1 single-dose study evaluating rivaroxaban granules for 
oral suspension formulation in pediatric subjects from 6 months to 12 years with 
previous thrombosis, currently starting enrollment. 
A total of 78 children have received a single dose of rivaroxaban in these Phase 1 studies.

Two Phase 2 studies (Study #14373 and #14374) are enrolling pediatric subjects from 
6 months to 18 years of age. Both studies investigate the safety, tolerability, effectiveness 
and pharmacokinetics and pharmacodynamics of a 30-day treatment of age- and body weight 
adjusted rivaroxaban. The pediatric dose targets an adult exposure of 20 mg in children with 
various manifestations of thrombosis. 
A total of 57 pediatric subjects have received rivaroxaban in these Phase 2 studies.

Study #14372 is a Phase 3 study in pediatric subjects from 6 months to <18 years. It is a 3 to 
12 month, open-label, active-controlled, randomized study of the safety, efficacy and the 
pharmacokinetic and pharmacodynamic properties of oral rivaroxaban in pediatric subjects 
with various manifestations of venous thrombosis. The study is currently enrolling the age 
cohort 12 to 18 years. A total of 87 subjects have received rivaroxaban.


Study # 17618 is a Phase 1/2 7-day study of safety, efficacy and the pharmacokinetic and 
pharmacodynamic properties of oral rivaroxaban in pediatric subjects from birth to 6 months 
with catheter-related arterial or venous thrombosis. Pediatric subjects will be receiving an 
age- and body weight-adjusted dose of rivaroxaban (20 mg equivalent). Enrollment is 
currently starting, and 1 subject has received rivaroxaban.

Study #17625 is a Phase 3 study in pediatric subjects from birth to 6 months planned to start 
in 2017.
In the ongoing rivaroxaban studies in pediatric subjects, rivaroxaban has been well tolerated; 
there have been no cases of drug-related death and no major bleeding events. 
No recurrences of VTE have been observed during rivaroxaban treatment in phase 2 studies. In 
the Phase 3 study 14372 with a 2:1 randomization to the rivaroxaban and standard of care arm, 
there were 3 outcomes in the rivaroxaban arm (including 1 recurrence that occurred during the 
initial heparin treatment, ie, before rivaroxaban was started) and 1 outcome in the standard of 
care arm. The side effect profile of rivaroxaban has been similar to the side effect profile in 
adults. In summary, these data support a positive risk/benefit assessment.
1.2.
Comparator Agent
Acetylsalicylic acid (ASA)
Acetylsalicylic acid is a nonsteroidal anti-inflammatory drug (NSAID). The mechanism of action 
of ASA is suppression of prostaglandins and thromboxanes production by irreversible 
inactivation of the cyclooxygenase enzyme required for prostaglandin and thromboxane 
synthesis.
Acetylsalicylic acid is indicated as a pain reliever for the temporary relief of minor aches and
pains. It also has an antiplatelet effect and at lower doses can be used as a long-term treatment to 
help prevent heart attacks, strokes, and blood clot formation in patients at high risk of developing 
blood clots.
Adverse reactions associated with the use of ASA include allergic reactions, an increased risk of 
gastrointestinal bleeding, and Reye's syndrome.
Further information regarding low dose ASA can be found in the local approved product label.
1.3.
Overall Rationale for the Study
Despite continuous improvements in the medical management of pediatric patients with CHD, 
the risk of thrombotic events remains an important complication for pediatric patients following 
the Fontan procedure.21
The National Heart, Lung and Blood Institute (NHLBI) convened a Working Group in 2012 to 
explore the issues related to thrombosis in children with CHD.19 The report from the Working 
Group identified single ventricle patients as a priority population and further noted that studies to 
evaluate thromboprophylaxis in this patient population both before and after the Fontan 
procedure were a top research priority. Therefore, there is an important unmet medical need for 

JNJ-39039039; BAY 59-7939   (rivaroxaban)
Clinical Protocol 39039039CHD3001 - Amendment INT-2
26
Approved, Date: 27 July 2017
additional therapies with well controlled studies upon which to base treatment decisions for 
thromboprophylaxis in children after the Fontan procedure. 
There has been only 1 prospective study of anticoagulation prophylaxis in Fontan patients, which 
included 111 pediatric subjects that were randomized to treatment with ASA or heparin/warfarin 
for 2 years. The study did not reach the targeted recruitment goal of 242 subjects. Thrombotic 
events (venous and arterial) were the primary endpoints in the study. Results demonstrated a 
peak incidence of VTE in the first 6 months, and no significant difference in event rates between 
the treatment groups with thrombosis occurring in 21% of ASA-treated subjects and 24% of 
warfarin-treated subjects. The study found no difference in risk of thrombosis between subjects 
randomized to warfarin at the 2 years study endpoint. All of the thrombotic events in the study 
were venous events (no arterial events).20 Although there was no difference between warfarin 
and ASA, the event rate supports the decision to include an active comparator for which there is 
a perceived equipoise. 
To date, no consensus exists in the literature or in routine clinical practice as to the optimal type 
or duration of antithrombotic therapy for thromboprophylaxis after Fontan surgery and much of 
the data for pediatric recommendations is still extrapolated from adult data.11,18
Current 
guidelines recommend the use of ASA, or unfractionated heparin followed by vitamin K 
antagonist (VKA) for thromboprophylaxis in pediatric subjects after the Fontan procedure.12,11,18
While these recommendations are based on available literature and experts opinion and are 
routinely followed by pediatric hematologists and other health care providers, currently there are 
no anticoagulants approved for use in children for treatment or prophylaxis of thromboembolism 
in the United States  or European Union . Instead, anticoagulants (namely, VKAs and heparins) 
are currently used off-label in children. Furthermore, there is a negligible amount of published 
data on the safety and efficacy of novel oral anticoagulation agents in children for whom 
anticoagulation is recommended.
This study aims to provide safety and efficacy information on the use of rivaroxaban, an oral 
anticoagulant, compared to ASA, an antiplatelet, in this population.

OBJECTIVES AND HYPOTHESIS
2.1.
Objectives  
Primary Objectives
Part A
To characterize the single- and multiple-dose PK and PK/ PD profiles after oral rivaroxaban 
therapy administered to pediatric subjects 2 to 8 years of age with single ventricle physiology 
who have completed the Fontan procedure within 4 months prior to enrollment.
Part B
To evaluate the safety and efficacy of rivaroxaban, administered twice daily (exposure matched 
to rivaroxaban 10 mg once daily in adults) compared to ASA, given once daily (approximately 
5 mg/kg) for thromboprophylaxis in pediatric subjects 2 to 8 years of age with single ventricle 
physiology who have completed the Fontan procedure within 4 months prior to enrollment.
Secondary Objectives
Part A
To assess the safety and tolerability of rivaroxaban treatment.
Part B
To further characterize the PK and PK/PD profiles of rivaroxaban.
2.2.
Hypothesis
Children with CHD who underwent a Fontan procedure will respond to FXa inhibition by 
rivaroxaban in a similar manner as seen in adults. This hypothesis is supported by ex vivo 
spiking experiments, which covered the entire rivaroxaban concentration in clinical studies 
ranging up to 500 ng/mL, and in which similar exposure-response relationships existed in 
healthy children and adults of different age groups (23 days to 23 months, 2 to 6 years, 7 to 11 
years, 12 to 16 years, and adults).1,2
There is no statistical hypothesis testing for this study.

Overview of Study Design
This is a prospective, open-label, active-controlled, multicenter study designed to evaluate the 
PK and PK/PD profiles, safety, and efficacy of rivaroxaban for thromboprophylaxis in pediatric 
subjects 2 to 8 years of age with single ventricle physiology who have completed the Fontan 
procedure within 4 months prior to enrollment.

This study consists of 2 parts:

Part A: This is the 12-month, non-randomized, open-label part of the study, which includes a 
12-day Initial PK, PD, and Safety Assessment Period. An internal Data Review Committee 
(DRC) will assess before the subject returns for Day 12 the single- and multiple-dose 
rivaroxaban PK, PD, and the initial safety and tolerability data available from each subject, 
prior to the subject continuing in the study to complete the planned 12 months of open-label 
rivaroxaban therapy of Part A. Subjects in Part A will not participate in Part B. 
Randomization in Part B of this study will begin once the cumulative data from the Initial 
PK, PD, and Safety Assessment Period in Part A are deemed acceptable by the Independent 
Data Monitoring Committee (IDMC).

Part B: This is the randomized, open-label, active-controlled part of the study that will 
evaluate the safety and efficacy of rivaroxaban compared to ASA for thromboprophylaxis 
for 12 months. Subjects randomized to rivaroxaban will also have PK and PD assessments.
Subjects Participating in Part A 
Part A of the study will consist of an up to 21-day Screening Period, a 12-day Initial PK, PD, and 
Safety Assessment Period, a 12-month Open-Label Treatment Period, and a 30-day Follow-Up
Contact (phone contact) (see Time and Events Schedule). Approximately 10 pediatric subjects 
are planned to be enrolled in Part A.
Parental informed consent/child assent (as appropriate, typically at age ≥7 years or as defined by 
local regulations) must be obtained prior to performing any study-specific procedures. The 
screening assessments will take place after the Fontan procedure and up to 21 days before the 
first dose of rivaroxaban. During the screening period, baseline laboratory blood testing will be 
done and a transthoracic echocardiogram will be performed to rule out thrombosis. Laboratory 
parameters obtained as part of the post-surgery standard-of-care may be used for screening if 
they have been done within 21 days prior to receiving the first dose of rivaroxaban. The most 
recent post-Fontan clinical laboratory results will be used for screening if there are multiple 
laboratory results. Subjects who do not meet all of the enrollment criteria for the study may be 
rescreened 1 additional time as long as enrollment is within 4 months of their Fontan procedure.
Subjects who are rescreened will be assigned a new subject number, undergo the informed 
consent process, and then restart a new screening phase.
Subjects who meet all of the inclusion and none of the exclusion criteria will be enrolled and will 
receive the first dose of rivaroxaban oral suspension on Day 1 (on site). Rivaroxaban will be 
given twice daily for 12 days (+9 days). Pharmacokinetic and PD samples will be collected on 
Day 1 and Day 4 (+2 days) of rivaroxaban administration. An internal DRC will assess before 
the subject returns for Day 12 the PK, PD, and the safety data available from each subject, prior 
to the subject continuing in the study, to complete the planned 12 months of open-label 
rivaroxaban therapy. The subjects who are allowed to continue the 12-month treatment will also 
have PK and PD samples collected at Month 3 and Month 12. Safety and efficacy will be 
evaluated throughout the study. The assessment criteria will be described in the DRC charter.

Randomization in Part B of this study will begin once the cumulative data from the Initial PK, 
PD, and Safety Assessment Period in Part A are deemed acceptable by the IDMC. The decision 
tree of rivaroxaban exposure acceptability criteria will be described in the IDMC charter. The 
IDMC may stop enrollment into Part A and begin enrollment into Part B without changes, 
recommend to continue enrollment into Part A, or adjust the dose in Part B, depending on the 
results obtained.
Subjects Participating in Part B
For subjects randomized into Part B, there will be an up to a 21-day Screening Period, a 
12-month Open-Label Treatment Period and a 30-day Follow-Up Contact (phone contact) (see 
Time & Events Schedule). Subjects who do not meet all of the enrollment criteria for the study 
may be rescreened 1 additional time as long as enrollment is within 4 months of their Fontan 
procedure. Subjects who are rescreened will be assigned a new subject number, undergo the 
informed consent process, and then restart a new screening phase. Approximately 90 subjects 
who meet all of the inclusion and none of the exclusion criteria will be randomly assigned in a 
2:1 ratio to receive rivaroxaban oral suspension and ASA for 12 months.
Parental informed consent/child assent (as appropriate, typically at age ≥7 years or as defined by 
local regulations) must be obtained prior to performing any study-specific procedures. Subjects 
will undergo the same screening evaluations as in Part A. Eligible subjects will be enrolled and 
randomized on Day 1 and will receive their first dose of study drug on site at this visit. 
Pharmacokinetic and PD samples will be obtained on Day 1, Month 3, and Month 12 for subjects 
randomized to rivaroxaban only. Safety and efficacy will be evaluated throughout the study for 
all subjects.
Early Study Medication Discontinuation
For subjects in Part A and Part B who prematurely discontinue study drug for any reason, the 
Early Study Medication Discontinuation (ESMD) visit will be performed as soon as possible 
after discontinuation. A Follow-Up Contact (phone contact) will be performed 30 days following 
the last dose of study drug and at Month 12, the end of the planned treatment period. After 
cessation of the study drug, it is at the investigator’s discretion to continue with other 
antiplatelet/anticoagulant therapy. Every attempt must be made to ensure the subject is not lost to 
follow up.  
Note: An exception are subjects who are enrolled after local reading of the Screening 
transthoracic echocardiogram rules out thrombosis, and subsequently reported to have 
thrombosis after central reading by the core laboratory of the same transthoracic 
echocardiogram. These subjects will be withdrawn from the study when the result of the 
echocardiogram by the core laboratory becomes available. Subjects will be asked to return for 
the ESMD visit as soon as possible. They will not be required to have a repeat transthoracic 
echocardiogram as part of the ESMD. Subjects will go on to receive proper care according to the 
healthcare provider’s judgment. They will be contacted by phone approximately 30 days (+/-
7 days) after last dose of study drug (Follow-Up Contact). An ESMD Month 12 follow up visit 
will not be required.

No interim analysis will be performed for this Study. An IDMC will monitor the subject’s safety 
and give recommendations to the Executive Committee (EC). The IDMC has the responsibility 
to provide the EC and the sponsor with recommendations related to the protection of the 
pediatric subject’s safety, including stopping recruitment and study treatment. For that purpose, 
the IDMC will regularly review all incidences of serious adverse events, thrombotic events and 
bleeding events. Organizational aspects, responsibilities, and processes will be described in the 
IDMC charter.
Committees and Advisors
An EC, an internal DRC, IDMC, a Central Independent Adjudication Committee (CIAC),
Steering Committee (SC), and a Sponsor Committee, will be commissioned for this study. Refer 
to Section 9.7, Committees, for details.

Study Design Rationale
Study Population
Young pediatric subjects who have recently completed the initial Fontan procedure were chosen 
for this study because they are a population with a high thrombotic risk and for whom there is 
scant evidence-based information regarding thromboprophylaxis. Much of the data for pediatric 
recommendations for thromboprophylaxis are still extrapolated from adult data. Alternative 
thromboprophylaxis strategies should be studied in the post-Fontan population in light of the 
high prevalence of thrombotic events, difficulties achieving consistent protection with current
anticoagulant therapy, and the considerable residual risk that remains in children treated with 
warfarin or ASA. Results from this study would therefore fulfill an unmet medical need. 
Two-Part Study 
Because this is the first clinical study of rivaroxaban in pediatric post-Fontan subjects, this study 
is designed to first, evaluate the single- and multiple-dose PK properties of rivaroxaban in this 
population (Part A) to confirm the dose scheme chosen, and, second, to evaluate the safety and 
efficacy profiles of rivaroxaban when used for thromboprophylaxis for 12 months and compare 
them to those of ASA (Part B). Enrollment in Part B will begin once the cumulative data from 
the Initial PK, PD, and Safety Assessment Period in Part A are assessed by the IDMC. 
Dose and Dosing Regimen, Treatment Period
Because patients with known thrombosis will not be allowed to be enrolled in this study, this 
population will more closely be similar to a prophylaxis population than a treatment population.
The rivaroxaban dose to be used in this study was determined via an adapted PBPK modeling 
approach based on previously established and validated rivaroxaban PBPK modeling, used for 
the VTE pediatric studies and adapted to reflect the special physiology of the pediatric 
post-Fontan population.26,24 Rivaroxaban will be administered to the pediatric post-Fontan 
population as age- and body weight-adjusted dosing targeting exposure (as measured by AUC0-24 
at steady state), matching that of rivaroxaban 10 mg total daily dose in adults that has been 
shown to be safe and effective for thromboprophylaxis in adult subjects after major orthopedic 
surgery (Phase 3 RECORD studies).32
The pediatric PBPK model was also used to compare once- or twice-daily dosing options. 
Twice-daily dosing was chosen because it provided both, a lower Cmax that stayed completely 
within the adult reference range and a higher trough plasma concentration (Ctrough) that was 
sufficiently high to not fall below the lower adult PBPK modeling range. 
No relevant difference in Cmax is expected between the first dosing day and steady state in the 
population targeted in this study.
These subjects will be followed for 1 year because thrombus formation is most significant 
immediately following the Fontan procedure and has been noted to peak within the first 
postoperative year in particular.16,17

PK and PD Sampling Scheme
Pharmacokinetic and PD samples will be drawn on Day 1 and Day 4 of rivaroxaban treatment in 
Part A with the main goal of obtaining initial assessment of rivaroxaban exposure. 
Pharmacokinetic and PD samples will also be drawn at Month 3 and Month 12, to further enrich 
and refine the initial PK/PD model and to evaluate any adjustment in dose made at Month 6 due 
to the subjects’ weight gain. 
Comparator Selection
Subjects in Part B are randomized to ASA as the appropriate comparator to allow for the 
evaluation of benefit/risk of rivaroxaban as a thromboprophylactic agent in pediatric subjects 
who have single-ventricle physiology and who have completed the Fontan procedure. This 
decision was made based on careful consideration of the literature, existing guidelines for the 
standard-of-care practice, and current clinical practice in many centers. 
Current American College of Chest Physicians 2012 guidelines recommend ASA, or
unfractionated heparin followed by warfarin for this patient population.12 The American Heart 
Association, in a statement in 2013, suggested that long-term antiplatelet therapy for prevention 
of thrombosis is reasonable after the Fontan procedure and that prophylaxis with warfarin or 
LMWH may be reasonable after the Fontan procedure for patients with anatomic or 
hemodynamic risk factors.11 However, controversy remains in clinical practice as to the optimal 
prevention strategy to be followed, as there are no evidence-based recommendations.11,12 The 
only prospective, multicenter, randomized study published showed a similar cumulative risk for 
thrombosis between ASA (5 mg/kg/day) and heparin/warfarin treatment.20 In a secondary 
analysis of this study, risk reduction was observed in a small subset of subjects in the warfarin 
group who had adequate INR levels and in those on ASA, compared with subjects in the 
warfarin group with a high prevalence of sub therapeutic INR measurements (<30% INR 
measurements within the target range).18 These subjects had a significantly greater risk of 
thrombosis than those subjects who received ASA therapy alone. Because the factors associated 
with poorly controlled warfarin therapy in these subjects have not been identified yet, the authors 
of the study concluded that ASA might be the best current strategy to prevent thrombosis for this 
patient population.18 Using ASA as the comparator in this study will allow a descriptive 
comparison of results across 2 different drug classes: antiplatelet versus anticoagulant therapy 
within the period of highest incidence of thrombosis (up to 12 months after Fontan procedure). 
A new oral anticoagulant such as rivaroxaban, which demonstrated in studies in adults to be 
noninferior regarding efficacy but with more predictable and stable PK and easier to dose, may 
be a potential alternative to ASA or VKA treatment in the post-Fontan population.

Open-label and Randomization
Randomization will be used in Part B to minimize bias in the assignment of subjects to treatment 
groups, to increase the likelihood that known and unknown subject attributes (eg, demographic 
and baseline characteristics) are evenly balanced across treatment groups, and to enhance the 
validity of the descriptive comparisons between treatment groups. Open-label treatment will be 
used to allow for further evaluation of the PK and PK/PD profiles of rivaroxaban throughout the 
study.
Safety Assessments
As with any anticoagulant agent, the use of rivaroxaban is associated with an increased risk of 
bleeding events. Bleeding events will be assessed using the International Society on Thrombosis 
and Hemostasis (ISTH) classification to be consistent with the other rivaroxaban pediatric VTE 
treatment studies.5,27 All bleeding events will be adjudicated by the CIAC.
Efficacy Assessment
The efficacy outcomes of any thrombotic event (venous or arterial), defined as the appearance of 
a new thrombotic burden within the CV system on either routine surveillance or clinically 
indicated imaging, or the occurrence of a clinical event known to be strongly associated with 
thrombus (such as cardioembolic stroke, pulmonary embolism), are accepted, validated, clinical 
endpoints for the evaluation of thromboprohylaxis. All transthoracic echocardiograms will be 
taken under a standardized protocol and will be read in a blinded manner at a central laboratory 
to minimize inter-site variability and bias.

TREATMENT ALLOCATION AND BLINDING
Subjects in Part A will not be randomized.
Treatment Allocation
Procedures for Randomization in Part B
Subjects will be randomly assigned to 1 of 2 treatment groups based on a computer-generated 
randomization schedule prepared before the study by or under the supervision of the sponsor. 
The randomization ratio will be 2:1 for rivaroxaban and ASA. The randomization will be 
balanced by using randomly permuted blocks. Based on this randomization code, the study drug 
will be packaged and labeled for each subject. Study drug code numbers will be preprinted on 
the study drug labels and assigned as subjects qualify for the study and are assigned to treatment.
The interactive web response system (IWRS) will assign a unique treatment code for each 
subject, which will dictate the treatment assignment and matching study drug kit for the subject. 
The requestor must use his or her own user identification and personal identification number 
when contacting the IWRS to receive the relevant subject details to uniquely identify the subject.
Blinding
As this is an open-label study, blinding procedures are not applicable.
6.
DOSAGE AND ADMINISTRATION
Rivaroxaban: The rivaroxaban dose to be used in this study was determined via an adapted 
PBPK modeling approach.26 Rivaroxaban will be administered twice daily in an open-label 
fashion as a 0.1% (1 mg/ml) oral suspension with target exposure (AUC0-24 at steady state)
matching to that of rivaroxaban 10 mg total daily dose in adults (age- and body weight-adjusted 
dosing [see Table 1]). Because children with an estimated glomerular filtration rate below 
30 mL/min/1.73 m2 are excluded from the study, dose reduction for impaired renal function is 
not required. Rivaroxaban will be taken in the morning and in the evening (approximately 
12 hours apart) at approximately the same times each day as described in the study booklet. Dose 
adjustment, due to increased body weight, will be made at Month 6 (both Part A and Part B).

ASA: Acetylsalicylic acid will be provided as 81-mg or 100-mg tablets according to local 
practice. Subjects randomized to ASA will receive approximately 5 mg/kg of ASA to a 
maximum of 1 whole tablet as a single daily dose as described in the study booklet. Tablets can 
be split in half, if necessary (eg. children weighing ≤10 kg), to meet the daily dose, and the dose 
must be documented. It is recommended that tablets are not split more than in half. Dose 
adjustments due to increased body weight, will be made at Month 6.
Temporary discontinuation of the study drug is allowed for events, such as intercurrent illnesses. 
In this case, standard clinical practice should be followed. See Section 10.2.1, Temporary 
Discontinuation of Study Treatment. All interruptions of study drug must be recorded in the 
eCRF.
Throughout the study, study drug will be dispensed at appropriate intervals (see the Time and 
Events Schedule) to ensure that subjects have adequate quantities of study drug between study 
visits. Study-site personnel will instruct parents/legally acceptable representatives on the proper 
administration and storage of study drug for at-home use.
Detailed instructions on the administration of the oral suspension will be provided in the study 
booklet.
Missed Dose
Rivaroxaban: is taken in a twice daily regimen. A missed morning dose should be taken 
immediately when it is noticed, any time during the calendar day, which could include taking it 
together with the evening dose. A missed evening dose should only be taken in the same evening. 
On the following day, the subject should continue with the regular twice daily regimen. A missed 
dose from a previous calendar day should not be taken.

ASA: if a dose of ASA is missed the subject should take the missed dose immediately when it is 
noticed within the same calendar day. On the following day, the subject should continue with the 
regular once daily regimen. A missed dose from a previous calendar day should not be taken.
Intentional stopping of study drug by the subject, unintentional stopping of study drug for more 
than 7 consecutive days, or temporary stopping of study drug as directed by the investigator or 
other physician will be documented. Study drug interruptions will be recorded in the eCRF. 
Vomiting and/or Spitting After Dosing
If the subject immediately vomits and/or spits up the dose within 30 minutes after receiving a 
dose of study medicine (rivaroxaban or ASA), a second dose should be given. If the subject 
vomits more than 30 minutes after the first dose, a second dose must not be given to replace it. 
The parent should contact the study team if the subject spits up the dose or vomits after receiving 
the study medicine multiple times either the same day or on different days.

TREATMENT COMPLIANCE
The IWRS in Part A and Part B will keep track of study drug dispensed to the subjects. 
The investigator or designated study-site personnel will maintain a log of all study drug 
dispensed and returned. Drug supplies for each subject will be inventoried and accounted for 
throughout the study. 
8.
PRESTUDY, CONCOMITANT AND POSTSTUDY THERAPY
Any previous anticoagulant/antiplatelet medication taken after the Fontan procedure and prior to 
first dose of study drug will be documented as prestudy therapy. 
Concomitant medications include all medications received between the first dose and the last 
dose of study drug.
Any anticoagulant/antiplatelet medication initiated after the end of the study treatment period 
will also be documented on the concomitant medication eCRF page (see Section 9.1.5, 
Posttreatment Period [Follow-Up Contact]).

Study Procedures
9.1.1.
Overview
The Time and Events Schedule summarizes the frequency and timing of PK, PD, safety, and 
efficacy measurements applicable to this study.
The study consists of 2 parts: 

Part A of the study has an up to 21-day Screening Period, a 12-Month Open-Label 
Treatment Period (which includes a 12-day Initial PK, PD, and Safety Assessment Period), 
and a 30-day Follow-up Contact  

Part B of the study has an up to 21-day Screening Period, a 12-Month Open-Label 
Treatment Period and a 30-day Follow-up Contact  
For each subject in Part A, blood samples will be obtained at the timepoints noted in the Time 
and Events Schedule; the estimated amount of blood drawn in this study will be approximately 
33 mL over 12 months (a maximum of approximately 3.5 mL on each blood draw, except for 1 
blood draw each at the Month 3 and Month 12 visits, where 4.5 ml will be drawn). For details on 
the volumes and types of blood samples to be collected, see table in Attachment 1.  
For each subject in Part B, blood samples will be obtained at the timepoints noted in the Time 
and Events Schedule; the estimated amount of blood drawn in Part B will be approximately 25 
mL over a 12-month period (a maximum of approximately 3.5 ml on each blood draw, except for 
1 blood draw at the Month 12 visit, where 4.3 ml will be drawn). For details, see table in 
Attachment 1.
9.1.2.
Screening Period   
Subjects Participating in Part A 
Parental informed consent/child assent (as appropriate) must be obtained prior to performing any 
study-specific procedures. The screening assessments will take place after the Fontan procedure 
and up to 21 days before the first dose of study drug. During the screening period, baseline 
laboratory blood testing will be done and a transthoracic echocardiogram using a study-specific
protocol (see Attachment 2) will be performed to rule out thrombosis. Laboratory parameters 
obtained as part of the standard-of-care may be used as baseline safety if conducted within 21 
days prior to receiving the first dose of rivaroxaban. The most recent post-Fontan clinical 
laboratory results will be used for screening if there are multiple laboratory results. Subjects who 
do not meet all of the enrollment criteria for the study may be rescreened 1 additional time as 
long as enrollment is within 4 months of their Fontan procedure. Subjects who are rescreened 
will be assigned a new subject number, undergo the informed consent process, and then restart a 
new screening phase.

All screening activities must be completed before enrollment and the results must be available to 
the investigator for review to ensure that eligibility criteria are met. The IWRS will assign a 
unique subject identification number.
Subjects Participating in Part B
Parental informed consent/child assent (as appropriate) must be obtained prior to performing any 
study-specific procedures. Subjects will undergo the same screening evaluations as in Part A
except for PT and aPTT testing which will be performed on Day 1 prior to first dose of study 
drug.  
All screening activities
related to establishing eligibility must be completed before
randomization and the results must be available to the investigator for review to ensure that 
eligibility criteria are met. Subjects may be enrolled and randomized on the business day prior to 
Day 1 to facilitate logistics provided the investigator ensures that the subject meets all eligibility

Approved, Date: 27 July 2017
Pharmacokinetic and PD (PT and aPTT tests) blood samples will be sent to the central laboratory 
after the collection of the last sample on Day 4 (ie, after the 6.0 to 8.0 hour sample). Results are 
anticipated to be available for DRC review 4 to 6 days after the samples are received by the 
central laboratory.
An internal DRC will review the subject’s PK, PD and safety data obtained from the Initial PK, 
PD, and Safety Assessment Period prior to allowing the subject to continue on rivaroxaban 
therapy to complete the 12-month period. The sponsor will notify the investigator about the DRC 
decision prior to Visit 2-D12 (+ 9 days). At this visit, the subject will either be informed to 
continue on rivaroxaban in the 12-month Open-Label Treatment Period or be discontinued from 
the study. 
Subjects who continue on in the Open-Label Treatment Period will have up to 3 more planned 
visits: after 3 months (Visit 3), after 6 months (Visit 4), and after 12 months (Visit 5/End of 
Study), and a Follow-Up Contact  (phone contact) will be performed 30 days following the last 
dose of rivaroxaban.  
Transthoracic echocardiograms will be obtained at screening, Month 6, and at the end of the 
study (Month 12) or ESMD (for details see Section 9.1.6, Transthoracic Echocardiograms). PK
and PD blood samples will be collected at Month 3 and at Month 12. Safety and efficacy will be 
evaluated throughout the study.
Enrollment in Part A will end, and enrollment in Part B will start, once the cumulative data from 
the Initial PK, PD, and Safety Assessment Period are deemed acceptable by the IDMC.
Assessment criteria will be described in the IDMC charter.
For Safety and Efficacy evaluations see Section 9.3, Safety Evaluations/Outcomes, and 
Section 9.4, Efficacy Evaluations/Outcomes, respectively.


Phone call – Follow-Up Contact, 30 days after last study drug is taken.
Approximately 90 subjects are planned to be enrolled in Part B. Any visit may take place while 
the subject is hospitalized.
Subjects will be enrolled and randomized on Visit 2/Day 1 after meeting inclusion and exclusion 
criteria. Subjects may be enrolled and randomized on the business day prior to Day 1 to facilitate 
logistics provided the investigator ensures that the subject meets all eligibility criteria prior to 
randomization. The first dose of study drug will be administered on site on Day 1 if the subject is 
still eligible. Subjects will be contacted by phone at approximately 12 days (± 9 days) after the 
first dose to obtain safety and efficacy information after the start of study drug. Visits 3 and 4 are 
treatment visits and occur after 3 months and 6 months of therapy, respectively. Visit 5 is the end 
of study visit (Month 12). Transthoracic echocardiograms will be obtained at screening, at 
Month 6, and at the end of the study (Month 12), or ESMD visit (for details see Section 9.1.6,
Transthoracic Echocardiograms). Safety and efficacy will be evaluated throughout the study.
For subjects randomized to rivaroxaban, blood samples for PK and PD evaluations will be 
collected. For details see Section 9.2, Pharmacokinetics/Pharmacodynamics Evaluations.  
For Safety and Efficacy evaluations see Section 9.3, Safety Evaluations/Outcomes, and 
Section 9.4, Efficacy Evaluations/Outcomes, respectively.
9.1.4.
Unscheduled Visits
Additional site visits may be added as necessary, at the discretion of the investigator.
9.1.5.
Posttreatment Period (Follow-Up Contact)
In both Part A and Part B, all subjects will be contacted by phone at the following time periods:
1.
Subjects who complete the 12-Month treatment period or subjects who are withdrawn from 
the study will receive 1 phone contact: Approximately 30 days (+/-7 days) after last dose 
taken (Follow-Up Contact). A review of safety and efficacy outcomes will be conducted at 
this contact and any concomitant medications will be recorded.
2.
Subjects who permanently discontinue study drug early but continue in (are not withdrawn 
from) the study will receive 2 phone contacts: Approximately 30 days (+/- 7 days) after last 
dose taken (Follow-Up Contact) to review safety and efficacy outcomes and any 
concomitant medications; and at the end of the planned treatment period (ESMD 12 Month 
follow up) to determine their vital status and thrombotic events (no bleeding events).
Transition at End-of-Treatment 
If at the end of study treatment a decision is made to continue a subject on an anticoagulant or 
ASA, the following guidelines are provided:

Subjects who switch from rivaroxaban to heparin/LMWH/fondaparinux can switch at the 
time of the next scheduled dose.

Clinical Protocol 39039039CHD3001 - Amendment INT-2
44
Approved, Date: 27 July 2017

Subjects who switch from rivaroxaban to VKA need to continue rivaroxaban for 48 hours 
after the first dose of VKA. After 2 days of co-administration, an INR should be obtained 
prior to the next scheduled dose of rivaroxaban. Co-administration of rivaroxaban and VKA 
is advised to continue until the INR is ≥2.0.

Subjects who switch from rivaroxaban to ASA can switch to ASA at the time of the next 
scheduled dose.
Any anticoagulant/antiplatelet medication initiated at the end of the study treatment period will 
be documented on the concomitant medication eCRF page.
9.1.6.
Transthoracic Echocardiograms 
Transthoracic echocardiograms will be obtained according to the timepoints noted in the Time 
and Events Schedule for the assessment of thrombotic events. For the Screening post-Fontan 
transthoracic echocardiogram, the Post-Fontan Echocardiographic Examination protocol in 
Attachment 2 is to be followed, and the following guidelines will be applicable:

The subject is not to be enrolled if local reading of the Screening transthoracic 
echocardiogram confirms thrombosis. The subject’s transthoracic echocardiogram will not 
need to be sent to the core laboratory.

The subject may be enrolled if local reading of the Screening transthoracic echocardiogram 
rules out thrombosis and the remaining inclusion/exclusion criteria are satisfied. The 
Screening transthoracic echocardiogram is to be sent to the core laboratory for central 
reading.

The subject will be withdrawn from the study if the subject is enrolled after local reading
rules out thrombosis on the transthoracic echocardiogram and subsequently central reading 
by the core laboratory reports a thrombosis from the same transthoracic echocardiogram. 
The reasoning for the early withdrawal will be documented on the eCRF.
The core laboratory report will serve as the baseline for the comparison of the subsequent study 
transthoracic echocardiograms. 
Investigators can image as often as medically necessary or as needed based on their institution’s 
standard-of-care; however, protocol-based imaging must be performed according to the 
timepoints noted in the Time and Events Schedule. Echocardiograms will be sent to a core 
laboratory for blinded reading and to minimize inter-site variability and bias. During the course 
of the study, for subjects who prematurely discontinue study drug for any reason, the final 
echocardiogram will be performed as soon as possible after discontinuation at the ESMD visit. A 
detailed description of the echocardiogram core laboratory process will be provided in a separate 
manual. The Post-Fontan Echocardiographic Examination protocol is provided in Attachment 2.  
9.2.
Pharmacokinetics/Pharmacodynamics Evaluations
Blood samples for rivaroxaban PK and PD, including rivaroxaban plasma concentration, 
absolute PT, activated partial thromboplastin time (aPTT) and anti-FXa activity measurements 
will be taken from pediatric subjects enrolled in Part A and for subjects randomized to 
rivaroxaban in Part B at the timepoints noted in the Time and Events Schedule. Rivaroxaban

Clinical Protocol 39039039CHD3001 - Amendment INT-2
45
Approved, Date: 27 July 2017
plasma concentration will be determined using the validated liquid chromatography/mass 
spectrometry/mass spectrometry (LC-MS/MS) method. The dosing, exact time of rivaroxaban 
administration and PK and PD blood sampling will be documented in the eCRF. The exact time 
must be documented even if PK and PD samples are taken outside of the prespecified time 
window.
Ideally, PK and PD blood samples will be collected by venipuncture by an experienced pediatric 
phlebotomist. A local anesthetic cream can be applied at the venipuncture site to decrease
discomfort.
If blood samples are collected via an indwelling cannula, an appropriate amount (eg, 1 mL) of 
fluid slightly greater than the dead space volume of the lock will be removed from the cannula 
before each blood sample is taken (see Section 9.5, Sample Collection and Handling for more 
details).8
Detailed information about the handling and labeling of the samples will be provided in the 
laboratory manual.
Part A
Pharmacokinetic and PD blood samples will be collected on the first day of dosing (Visit 2/D1) 
between 0.5 to 1.5 hours and again between 1.5 to 4.0 hours postdose. Additional samples will 
be collected on Day 4 (Visit 2/D4), just prior to dose administration and again between 0.5 to 
1.5 hours, 1.5 to 4.0 hours, and 6.0 to 8.0 hours postdose. Pharmacokinetic and PD samples will 
be sent to the central laboratory after the collection of the last sample on Day 4 (ie, the 6.0 to 
8.0 hour sample). 
Rivaroxaban plasma concentration will be determined using the validated LC-MS/MS method. 
The blood samples on Day 1 and Day 4 will be taken as specified in Table 2. See Attachment 1
for details.
Pharmacokinetic and PD samples will also be taken at Month 3 and Month 12. See the Time and 
Events Schedule and Attachment 1 for details.
If rivaroxaban is temporarily stopped, PK and PD blood samples should only be obtained if 
rivaroxaban administration has been restarted and sustained for at least 3 days.

volume for all PD-2 samples is 4.2 mL (Day 1: 2.8 mL; Day 4: 1.4 mL). Sites will send samples to the central 
laboratory.
Part B
Pharmacokinetic and PD samples will also be collected and analyzed for subjects randomized to 
rivaroxaban in Part B. Pharmacokinetic and PD blood samples will be collected on the first day 
of dosing (Visit 2/D1) before first dosing (PT and aPTT only), between 0.5 to 1.5 hours and 
again between 1.5 to 4.0 hours postdose. Additional samples will be collected at Month 3 and 
Month 12. Please see Time and Events Schedule and Attachment 1 for details.
If rivaroxaban was temporarily stopped, PK and PD blood samples for Month 3 and Month 12
should only be obtained if rivaroxaban administration has been restarted and sustained for at 
least 3 days prior to the sampling.

Safety Evaluations/Outcomes
9.3.1.
Bleeding Events
The primary safety outcome will be major bleeding events, as defined below. Clinically relevant 
non-major bleeding events and trivial (minimal) bleeding will be secondary safety outcomes.
Bleeding events will be adjudicated by CIAC using the ISTH recommendations.5,27 The 
following bleeding criteria are consistent across the rivaroxaban pediatric program:
Major bleeding is defined as overt bleeding and:

Associated with a fall in hemoglobin of 2 g/dL or more; or

Leading to a transfusion of the equivalent of 2 or more units of packed red blood cells or 
whole blood in adults ; or

Occurring in a critical site: intracranial, intraspinal, intraocular, pericardial, intra-articular, 
intramuscular with compartment syndrome, retroperitoneal; or

Contributing to death.
Clinically relevant non-major bleeding is defined as overt bleeding not meeting the criteria for 
major bleeding but associated with:

Medical intervention, or

Unscheduled contact (visit or telephone call) with a physician, or

(Temporary) cessation of study treatment, or 

Discomfort for the subject such as pain, or 

Impairment of activities of daily life (such as loss of school days or hospitalization).
Trivial (minimal) bleeding is defined as any other overt bleeding event that does not meet criteria 
for clinically relevant non major bleeding.
9.3.2.
Approach to the Subject with a Bleeding Event
If a subject has a serious bleed during study treatment, the following routine measures could be 
considered by the treating physician:

Consider usual treatment for bleeding, including blood transfusion, and/or fresh frozen 
plasma if needed

Consider that other causes besides thromboprophylaxis medication can be contributory to 
the seriousness of the bleeding event (eg, thrombocytopenia, and other coagulopathies; 
kidney and liver dysfunction; concomitant medications), and treat accordingly 

Delay the next ASA or rivaroxaban administration or temporarily discontinue treatment, if 
indicated

Clinical Protocol 39039039CHD3001 - Amendment INT-2
48
Approved, Date: 27 July 2017

If the subject is treated with rivaroxaban, a blood sample for PK and PD testing should be 
obtained
NOTE: Partial reversal of prothrombin time prolongation has been seen after administration of 
prothrombin complex concentrates (PCCs) in healthy volunteers. The use of other procoagulant 
reversal agents like activated prothrombin complex concentrate (APCC) or recombinant factor 
VIIa (rFVIIa) has not been evaluated.
If severe bleeding cannot be controlled, however, consider administration of one of the following 
procoagulants (both according to the dosages advised in the package insert):

4 factor concentrate 

Recombinant factor VIIa (NovoSeven®) 
Protamine sulfate and vitamin K are not expected to affect the anticoagulant activity of 
rivaroxaban.
Any products administered to control bleeding should be entered in the CRF.
Parents/ legally acceptable representatives should call the study physician, if the subject has 
signs and symptoms of clinically significant bleeding, for example:

bleeding (eg, nose or gum bleeding) that does not stop within 10 minutes

coughing or throwing up blood

dark-colored urine or black stools

red or black-and-blue marks on the skin that get larger
If the subject has a bleeding incident, the parent/ legally acceptable representatives should 
consult the study physician in addition to their own cardiologist (if different) and always inform 
him/her of the date/time the subject took the last dose of anticoagulant medication. For severe 
bleeding, subjects should be moved to the nearest emergency room.
After resolution of the bleeding event, restarting study drug may be considered based on the 
clinical judgment of the investigator.  
9.3.3.
Other Safety Assessments
The safety and tolerability of rivaroxaban will also be evaluated by assessing other adverse 
events and clinical laboratory test values.
Any clinically relevant changes, including laboratory reports, occurring during the study must be 
recorded on the Adverse Event section of the eCRF. Any clinically significant abnormalities 
persisting at the end of the study/early withdrawal will be followed by the investigator until 
resolution or until a clinically stable endpoint is reached.

Approved, Date: 27 July 2017
The study includes the evaluations of safety and tolerability according to the time points 
provided in the Time and Events Schedule.
Adverse Events
Adverse events will be reported by the parents/legally acceptable representatives for the duration 
of the study up to the Follow-Up Contact (30-days after last dose). Adverse events will be 
followed by the investigator as specified in Section 12, Adverse Event Reporting.
Clinical Laboratory Tests
The following tests results with reference ranges will be obtained at the visits specified in the 
Time and Events Schedule. Either hospital laboratory/local laboratory results or central 
laboratory results are acceptable at the time of study screening period.  A central laboratory will 
be used during the rest of the study:

9.4.
Efficacy Evaluations/Outcomes
The primary efficacy outcome will be any thrombotic event (venous or arterial), defined as:

The appearance of a new thrombotic burden within the cardiovascular system on either 
routine surveillance or clinically indicated imaging, or

The occurrence of a clinical event known to be strongly associated with thrombus (such as 
cardioembolic stroke, pulmonary embolism).
Subjects who develop either a symptomatic or asymptomatic thrombotic event during the study 
must permanently discontinue the study drug. All thrombotic events and the primary cause of 
any death will be adjudicated by the CIAC. Transthoracic echocardiograms will be centrally read 
by an echocardiographic core laboratory. All available imaging results (eg, transthoracic or 
transesophageal echocardiograms, or MRIs), should be sent to the CIAC. Sites will be required 
to complete a worksheet, compile an adjudication package, and send it to the adjudication office
within 6 weeks from occurrence of the event.
After cessation of the study drug, it is at the investigator’s discretion to continue with other 
antithrombotic therapy. The investigator should document this therapy in the eCRF. Thrombotic 
events will not be reported as adverse events or serious adverse events, as they will be reported 
as efficacy outcomes, which will be documented in the eCRF.
9.5.
Sample Collection and Handling  
The actual dates and times of sample collection must be recorded in the eCRF or laboratory 
requisition form.
If blood samples are collected via an indwelling cannula, an appropriate amount (eg, 1 mL) of 
fluid slightly greater than the dead space volume of the lock will be removed from the cannula 
before each blood sample is taken. If a blood sample is taken from a central line, at least 3 mL of 
blood should be withdrawn prior to collecting study blood samples. Investigators should follow 
their institution’s policy for discarding or re-infusing withdrawn blood. Heparin can be used to 
maintain catheter patency; however, before collecting PK/PD samples, the catheter needs to be 
flushed with saline and the first volume of (diluted) blood should be withdrawn, as described 
above.
Refer to the Time and Events Schedule for the timing and frequency of all sample collections.
Instructions for the collection, handling, storage, and shipment of samples are found in the 
laboratory manual that will be provided. Collection, handling, storage, and shipment of samples 
must be under the specified, and where applicable, controlled temperature conditions as indicated 
in the laboratory manual.

10.2.1.
Temporary Discontinuation of Study Drug
Study drug may be temporarily discontinued if the subject: 

Undergoes any surgical procedure, or has a medical condition that may require temporary 
interruption of the study drug, or use of prohibited therapy due to bleeding risk, or use of 
other antiplatelet or anticoagulant therapy

Experiences a significant bleeding event

Develops a platelet count <50,000/L

Has any serious adverse event possibly related to or exacerbated by study drug 
administration

Requires a prohibited therapy on a temporary basis (see Section 8, Prestudy and 
Concomitant Therapy)
The investigator should consider stopping the study drug in pediatric subjects with elevated ALT 
values >5 x ULN and are increasing, or if ALT values remain unchanged at >5 x ULN with no 
change in total bilirubin for more than 2 weeks and are considered clinically relevant. In 
addition, investigators should also terminate the study drug in children with worsening clinical 
symptoms of liver injury and no other acceptable explanation. 
The study drug can be resumed at any time when in the opinion of the investigator it is safe to do 
so. Otherwise the subject will be permanently discontinued from study drug. 
10.2.2.
Permanent Discontinuation of Study Drug
A subject's study treatment should be discontinued permanently if:

The investigator believes that for safety reasons (eg, adverse event or persistent 
noncompliance) it is in the best interest of the subject to discontinue study treatment

The subject has a thrombotic event 

The subject develops any condition that requires treatment with anticoagulant or antiplatelet
therapy

The subject has a major bleeding event, eg, intracranial bleeding (for definitions of major 
bleeding see Section 9.3.1, Bleeding Events)

The subject, his or her parents/legally acceptable representatives request to discontinue the 
study drug permanently
For subjects in Part A and Part B who prematurely and permanently discontinue the study drug 
for any reason, the ESMD visit will be performed as soon as possible after discontinuation of the 
study drug. A Follow-Up phone contact will be performed 30 days following the last dose of the 
study drug. In addition, an ESMD Month 12 Follow-Up phone contact will be conducted at the 
end of the planned treatment period. This excludes subjects who are enrolled after local reading 
of the Screening transthoracic echocardiogram rules out thrombosis, and subsequently reported 
to have thrombosis after central reading by the core laboratory of the same transthoracic 
echocardiogram. These subjects will be withdrawn from the study when the result of the 
echocardiogram by the core laboratory becomes available. Subjects will be asked to return for

Approved, Date: 27 July 2017
the ESMD visit as soon as possible. They will not be required to have a repeat transthoracic 
echocardiogram as part of the ESMD. Subjects will go on to receive proper care according to the 
healthcare provider’s judgment. They will be contacted by phone approximately 30 days (+/-
7 days) after last dose of study drug (Follow-Up Contact). An ESMD Month 12 follow up visit 
will not be required.
10.3.
Withdrawal from the Study
A subject will be withdrawn from the study for any of the following reasons:

Lost to follow-up

Withdrawal of consent/assent

An internal DRC considers that the subject should not continue rivaroxaban treatment after 
the Initial PK, PD and Safety Assessment Period

The core laboratory reports a thrombosis on the same Screening transthoracic 
echocardiogram that was ruled out by the local reader.  

Other – eg, termination of the study by the sponsor, closing of study sites
When a subject withdraws before completing the study, the reason for withdrawal is to be 
documented in the eCRF and in the source document. Study drug assigned to the withdrawn 
subject may not be assigned to another subject. 
If a subject is withdrawn before the end of the study for reasons other than being lost to 
follow-up, the ESMD assessments should be obtained as soon as possible and a Follow-up phone 
contact will be performed approximately 30 days (+/-7 days) after last dose of study drug. This 
excludes subjects withdrawn after central reading by the core lab reports a thrombosis on 
Screening transthoracic echocardiogram. See Section 10.2, Discontinuation of Study Drug for 
more details. 
If a subject is lost to follow-up, every reasonable effort must be made by the study site personnel 
to contact the subject and determine the reason for discontinuation/withdrawal. The measures 
taken to follow up must be documented.
Subjects who withdraw will not be replaced.
If a subject is unwilling or unable to return for follow-up visits in person or have follow-up 
contacts, the sites should collect as much follow-up visit information as possible, including 
contacting the subject or the subject’s representative or health care professional, by telephone or 
by mail, to determine vital status and if an endpoint event has occurred, as agreed to by the 
subject and/or the subject’s representative during the initial informed consent process. If 
applicable, vital status may be obtained by reviewing the subject’s medical or public records 
unless this process is not allowed by local regulations.

STATISTICAL METHODS
Statistical analysis will be done by the sponsor or under the authority of the sponsor. A general 
description of the statistical methods to be used to analyze the PK, PK/PD, safety, and the 
efficacy data is outlined below. Specific details will be provided in the Statistical Analysis Plan
(SAP), including, if necessary, censoring rules for time-to-event analyses and imputation rules 
for missing or partially missing dates.
The SAP will be finalized prior to first subject enrolled in the study. 
Data from subjects participating in Part A of the study are planned to be combined with data 
from subjects in Part B of the study who were randomized to rivaroxaban. Summaries will also 
be provided based on data from: (a) randomized subjects only (rivaroxaban vs. ASA) from 
Part B, and (b) subjects participating in Part A only.
For both parts of the study, safety and efficacy results (adverse events, bleedings, and thrombotic 
events) will be summarized. All summaries will be presented using appropriate descriptive 
statistics for study variables including demographic and baseline characteristics. Descriptive 
statistics such as mean, median, standard deviation, minimum, and maximum will be used to 
summarize continuous variables. Counts and percentages will be used to summarize categorical 
variables. 
The best available data for safety events will be used by the DRC and IDMC to review subjects 
in the Initial PK, PD, and Safety Assessment Period of Part A. The CIAC-adjudicated results will 
be used in the final analysis for all subjects.
No statistical hypothesis will be tested in this study.

Analysis Populations and Periods
11.1.1.
Subject Information
Each summary or analysis involves the following 2 aspects: 1) analysis set, specifying the 
subjects to be included; and 2) analysis period, specifying the time window within which data 
will be included.
Key analysis sets and analysis periods are defined below.
11.1.2.
Analysis Sets  
Full Analysis Set: This analysis set consists of all subjects in Part A who receive at least 1 dose 
of study drug and all subjects in Part B who complete randomization and receive at least 1 dose 
of study drug.

56
Approved, Date: 27 July 2017
Safety Analysis Set: This is the same as Full Analysis Set.
PK Analysis Set: All subjects who received at least 1 dose of study drug and have quantifiable 
rivaroxaban plasma concentrations will be included in the descriptive PK analysis. 
PD Analysis Set: All subjects who received at least 1 dose of study drug and have quantifiable 
PT, aPTT, and anti-FXa activity values will be included in the descriptive PD analysis.
11.1.3.
Analysis Periods
On-Treatment Period: This analysis period includes all data from the first dose of study drug to 
2 days after the last dose of the study drug administration (inclusive). 
Up-to-End-of-Treatment Period: This analysis period includes all data from first dose to end of 
treatment visit (Month 12 or ESMD visit).
11.2.
Sample Size Determination
A total of at least 100 pediatric subjects overall are planned to be enrolled in this study. Due to 
the limited availability of the study population and the expected low event rates, this study is not 
powered to test a formal hypothesis for efficacy. The total sample size is based on regulatory 
feedback to obtain sufficient safety data in this pediatric population.
The sample size of approximately 10 subjects for Part A is considered adequate for the initial 
assessment of the rivaroxaban PK in the studied pediatric subjects. Approximately 90 subjects 
will be enrolled into Part B of the study. 
11.3.
Pharmacokinetics/Pharmacodynamics Analyses
Descriptive statistics will be used to summarize rivaroxaban PK data for each time interval. 
Pharmacodynamic measurements, including PT, aPTT, and anti-FXa activity will be plotted 
against rivaroxaban plasma concentrations and will also be summarized by timepoint.
Rivaroxaban PK parameters including AUC0-24, Cmax after single dose and AUC0-24, Cmax, and 
minimum plasma concentration (Cmin) at steady state will be derived through model-based 
methods. The PK/PD relationship will be quantified. Results from PK and PK/PD analyses will 
be reported separately from the Clinical Study Report. When appropriate, PK and PD data 
collected in this study may be used for ad hoc meta-analyses to further explore PK/PD 
relationships of rivaroxaban in pediatric subjects.
11.4.
Safety Analyses  
All safety analyses will be performed on the Safety Analysis Set (described in Section 11.1.2, 
Analysis Sets) and by treatment group as received.

Approved, Date: 27 July 2017
Bleeding Events
Bleeding events that occur during the On-Treatment Period will be summarized by treatment 
group. Bleeding events observed more than 2 days after stopping the study drug will be 
summarized separately. Individual listings of major and clinically relevant non-major bleeding 
events will be provided. The bleeding events will be adjudicated by the CIAC. 
Cumulative incidences and incidence rates over time based on time to the first bleeding event 
will be provided by treatment group using the Kaplan-Meier method.
Adverse Events
Overall safety will also be assessed by summarizing adverse events by treatment group.
The verbatim terms used in the eCRF by investigators to identify adverse events will be coded 
using the Medical Dictionary for Regulatory Activities (MedDRA). Treatment-emergent adverse 
events are adverse events with onset during the treatment period or that are a consequence of a 
pre-existing condition that has worsened since baseline. All reported adverse events will be 
included in the analysis. For each adverse event, the percentage of subjects who experience at 
least 1 occurrence of the given event will be summarized by treatment group. In addition, 
comparisons between treatment groups will be provided if appropriate.
Individual listings of adverse events (including treatment group, age, weight, height, gender, 
adverse event as reported, start, duration, severity, and relationship to the study drug) will be 
provided. The incidence of treatment-emergent adverse events will be summarized by treatment 
using MedDRA preferred terms grouped by primary system organ class.
Summaries, listings, datasets, or subject narratives may be provided, as appropriate, for those 
subjects who die, who discontinue treatment due to an adverse event, or who experience a severe 
or a serious adverse event. Additional summaries, listings, or subject narratives may be provided, 
as appropriate.  
Clinical Laboratory Tests   
This study will collect laboratory data at the timepoints specified in the Time and Events 
Schedule. Laboratory data will be summarized by treatment group. 
11.5.
Efficacy Analysis 
Efficacy analyses will be performed on the Full Analysis Set, excluding subjects who start on 
study drug but are discontinued if central reading by the core laboratory reports thrombosis on
the Screening transthoracic echocardiogram. These subjects will be included however in the 
safety analysis. Thrombotic events that occur during the Up-to-End-of-Treatment Period will be 
summarized by treatment received. Events that occur after Up-to-End-of-Treatment Period 
(after Month 12 or ESMD visit) will be summarized separately.
The efficacy outcomes will be adjudicated by CIAC.

ADVERSE EVENT REPORTING
Parents/legally acceptable representatives will receive a study booklet, specifying for both 
treatment groups important study-related information (see Section 9.6, Study Booklet).  
Timely, accurate, and complete reporting and analysis of safety information from clinical studies 
are crucial for the protection of subjects, investigators, and the sponsor, and are mandated by 
regulatory agencies worldwide. The sponsor has established Standard Operating Procedures in 
conformity with regulatory requirements worldwide to ensure appropriate reporting of safety 
information; all clinical studies conducted by the sponsor or its affiliates will be conducted in 
accordance with those procedures.
12.1.
Definitions
12.1.1.
Adverse Event Definitions and Classifications
Adverse Event
An adverse event is any untoward medical occurrence in a clinical study subject administered a 
medicinal (investigational or non-investigational) product. An adverse event does not necessarily 
have a causal relationship with the treatment. An adverse event can therefore be any unfavorable 
and unintended sign (including an abnormal finding), symptom, or disease temporally associated 
with the use of a medicinal (investigational or non-investigational) product, whether or not 
related to that medicinal (investigational or non-investigational) product. (Definition per 
International Conference on Harmonisation [ICH])
This includes any occurrence that is new in onset or aggravated in severity or frequency from the 
baseline condition, or abnormal results of diagnostic procedures, including laboratory test 
abnormalities.
Note: The sponsor collects adverse events starting with the signing of the ICF (refer to 
Section 12.3.1, All Adverse Events, for time of last adverse event recording).
Serious Adverse Event
A serious adverse event based on ICH and EU Guidelines on Pharmacovigilance for Medicinal 
Products for Human Use is any untoward medical occurrence that at any dose:

Results in death

Is life-threatening
(The subject was at risk of death at the time of the event. It does not refer to an event that 
hypothetically might have caused death if it were more severe.)

Requires inpatient hospitalization or prolongation of existing hospitalization

Results in persistent or significant disability/incapacity

Clinical Protocol 39039039CHD3001 - Amendment INT-2
59
Approved, Date: 27 July 2017

Is a congenital anomaly/birth defect

Is a suspected transmission of any infectious agent via a medicinal product

Is Medically Important*
*Medical and scientific judgment should be exercised in deciding whether expedited reporting is 
also 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 subject 
or may require intervention to prevent one of the other outcomes listed in the definition above. 
These should usually be considered serious.
For the purposes of this study, efficacy outcome events (thrombotic events) will not be reported 
as adverse events or serious adverse events, as they will be reported as efficacy outcomes (See 
Section 12.3.1, All Adverse Events.). 
Serious bleeding events will be considered serious adverse events and must be reported to the 
sponsor in an expedited manner as any other serious adverse events.
If a serious and unexpected adverse event occurs for which there is evidence suggesting a causal 
relationship between the study drug and the event, the event must be reported by the sponsor as a 
serious and unexpected suspected adverse reaction even if it is a component of the study 
endpoint. 
Unlisted (Unexpected) Adverse Event/Reference Safety Information
An adverse event is considered unlisted if the nature or severity is not consistent with the 
applicable product reference safety information. For rivaroxaban, the expectedness of an adverse 
event will be determined by whether or not it is listed in the Investigator's Brochure.
Adverse Event Associated With the Use of the Drug
An adverse event is considered associated with the use of the drug if the attribution is possible, 
probable, or very likely by the definitions listed below in Section 12.1.2, Attribution Definitions.
12.1.2.
Attribution Definitions
Not Related
An adverse event that is not related to the use of the drug.
Doubtful
An adverse event for which an alternative explanation is more likely, eg, concomitant drug(s), 
concomitant disease(s), or the relationship in time suggests that a causal relationship is unlikely.
Possible
An adverse event that might be due to the use of the drug. An alternative explanation, 
eg, concomitant drug(s), concomitant disease(s), is inconclusive. The relationship in time is 
reasonable; therefore, the causal relationship cannot be excluded.

Clinical Protocol 39039039CHD3001 - Amendment INT-2
60
Approved, Date: 27 July 2017
Probable
An adverse event that might be due to the use of the drug. The relationship in time is suggestive 
(eg, confirmed by dechallenge). An alternative explanation is less likely, eg, concomitant 
drug(s), concomitant disease(s).
Very Likely
An adverse event that is listed as a possible adverse reaction and cannot be reasonably explained 
by an alternative explanation, eg, concomitant drug(s), concomitant disease(s). The relationship 
in time is very suggestive (eg, it is confirmed by dechallenge and rechallenge).
12.1.3.
Severity Criteria 
An assessment of severity grade will be made using the following general categorical 
descriptors:
Mild: Awareness of symptoms that are easily tolerated, causing minimal discomfort and not 
interfering with everyday activities.
Moderate: Sufficient discomfort is present to cause interference with normal activity.
Severe: Extreme distress, causing significant impairment of functioning or incapacitation. 
Prevents normal everyday activities.
The investigator should use clinical judgment in assessing the severity of events not directly 
experienced by the subject (eg, laboratory abnormalities).
12.2.
Special Reporting Situations
Safety events of interest on a sponsor study drug that may require expedited reporting and/or 
safety evaluation include, but are not limited to:

Overdose of a sponsor study drug

Suspected abuse/misuse of a sponsor study drug

Accidental or occupational exposure to a sponsor study drug

Any failure of expected pharmacologic action (ie, lack of effect) of a sponsor study drug

Unexpected therapeutic or clinical benefit from use of a sponsor study drug

Medication error involving product preparation or dose administration of a sponsor product 
(with or without subject/patient exposure to the sponsor study drug, eg, name confusion)
Special reporting situations should be recorded in the eCRF. Any special reporting situation that 
meets the criteria of a serious adverse event should be recorded on the serious adverse event page 
of the eCRF

Procedures
12.3.1.
All Adverse Events  
Adverse events should be reported by the subjects or their parents/legally acceptable
representatives for the duration of the study. 
For the purposes of this study, thrombotic events will be captured in the eCRF and in the 
database as efficacy outcomes only, and will not be reported as adverse events or serious adverse 
events, regardless of seriousness and severity, except for those thrombotic events that ended in 
death. All other thrombotic events will be exempted from expedited reporting.
Any serious adverse events other than thrombotic events will be reported to the sponsor in an 
expedited fashion according to Section 12.3.2, Serious Adverse Events. 
All deaths (including those due to thrombotic causes) will be reported as serious adverse events. 
All bleeding events will be collected on the eCRF as a bleeding event and as an adverse event or
serious adverse event as appropriate. Serious bleeding events must be reported to the sponsor in 
an expedited manner as any other serious adverse events.  
Certain adverse events are considered to be Adverse Events of Special Interest and should be 
reported as serious adverse events. These include:

Suspected toxic effect on the bone marrow including severe thrombocytopenia (platelet 
count less than 50 x 109/L), severe neutropenia (white blood cell count less than 500/L), 
pancytopenia, aplastic anemia

Suspected severe hypersensitivity reaction (eg, anaphylaxis, angioedema, severe urticaria, 
bronchospasm, etc.)

Severe skin reactions such as Stevens-Johnson Syndrome

Suspected severe liver injury and concurrent elevations of ALT >5x ULN and total bilirubin 
>2x ULN 
All adverse events and special reporting situations, whether serious or nonserious, will be 
reported from the time a signed and dated ICF is obtained until completion of the subject's last 
study-related procedure (ie, Follow-Up Contact [phone contact]). 
Serious adverse events, including those spontaneously reported to the investigator within 30 days
after the last dose of study drug, must be reported via facsimile (fax) when applicable using the 
Serious Adverse Event page of the eCRF. The sponsor will evaluate any safety information that 
is spontaneously reported by an investigator beyond the time frame specified in the protocol.
All adverse events, regardless of seriousness, severity, or presumed relationship to study drug, 
must be recorded using medical terminology in the source document and the eCRF. Whenever 
possible, diagnoses should be given when signs and symptoms are due to a common etiology 
(eg, cough, runny nose, sneezing, sore throat, and head congestion should be reported as "upper

respiratory infection"). Investigators must record in the eCRF their opinion concerning the 
relationship of the adverse event to study therapy. All measures required for adverse event 
management must be recorded in the source document and reported according to sponsor 
instructions.
The sponsor assumes responsibility for appropriate reporting of adverse events to the regulatory 
authorities. The sponsor will also report to the investigator (and the head of the investigational 
institute where required) all suspected unexpected serious adverse reactions (SUSARs). The 
investigator (or sponsor where required) must report SUSARs to the appropriate Independent 
Ethics Committee/Institutional Review Board (IEC/IRB) that approved the protocol unless 
otherwise required and documented by the IEC/IRB. A SUSAR will be reported to regulatory 
authorities unblinded. Participating investigators and IEC/IRB will receive a blinded SUSAR 
summary, unless otherwise specified.
For all studies with an outpatient phase, including open-label studies, parent/legally acceptable 
representative must be provided with a "wallet (study) card" and instructed to carry this card with 
them for the duration of the study indicating the following:

Study number

Statement, in the local language(s), that the subject is participating in a clinical study

Investigator's name and 24-hour contact telephone number

Local sponsor's name and 24-hour contact telephone number (for medical staff only)

Site number

Subject number

Any other information that is required to do an emergency breaking of the blind
12.3.2.
Serious Adverse Events
All serious adverse events occurring during the study must be reported to the appropriate sponsor 
contact person by study-site personnel within 24 hours of their knowledge of the event.
Information regarding serious adverse events will be transmitted to the sponsor using the Serious 
Adverse Event page of the eCRF, which must be completed and signed by a physician from the 
study site, and transmitted to the sponsor within 24 hours. The initial and follow-up reports of a 
serious adverse event should be transmitted electronically via facsimile (fax).
All serious adverse events that have not resolved by the end of the study, or that have not 
resolved upon discontinuation of the subject's participation in the study, must be followed until 
any of the following occurs:

The event resolves

The event stabilizes

The event returns to baseline, if a baseline value/status is available

63
Approved, Date: 27 July 2017

The event can be attributed to agents other than the study drug or to factors unrelated to 
study conduct

It becomes unlikely that any additional information can be obtained (subject or health care 
practitioner refusal to provide additional information, lost to follow-up after demonstration 
of due diligence with follow-up efforts)
Suspected transmission of an infectious agent by a medicinal product will be reported as a 
serious adverse event.
Any event requiring hospitalization (or prolongation of hospitalization) that occurs during the 
course of a subject's participation in a study must be reported as a serious adverse event, except 
hospitalizations for the following:

For the purposes of this study, thrombotic events will not be reported as serious adverse 
events, refer to Section 12.3.1, All Adverse Events for details.

Hospitalizations not intended to treat an acute illness or adverse event (eg, social reasons 
such as pending placement in long-term care facility)

Surgery or procedure planned before entry into the study (must be documented in the 
eCRF). Note: Hospitalizations that were planned before the signing of the ICF, and where 
the underlying condition for which the hospitalization was planned has not worsened, will 
not be considered serious adverse events. Any adverse event that results in a prolongation of 
the originally planned hospitalization is to be reported as a new serious adverse event.
The cause of death of a subject in a study, whether or not the event is expected or associated with 
the study drug, is considered a serious adverse event.
12.4.
Contacting Sponsor Regarding Safety
The names (and corresponding telephone numbers) of the individuals who should be contacted 
regarding safety issues or questions regarding the study are listed on the Contact Information 
page(s), which will be provided as a separate document.

PRODUCT QUALITY COMPLAINT HANDLING
A product quality complaint (PQC) is defined as any suspicion of a product defect related to 
manufacturing, labeling, or packaging, ie, any dissatisfaction relative to the identity, quality, 
durability, or reliability of a product, including its labeling or package integrity. A PQC may have 
an impact on the safety and efficacy of the product. Timely, accurate, and complete reporting and 
analysis of PQC information from studies are crucial for the protection of subjects, investigators, 
and the sponsor, and are mandated by regulatory agencies worldwide. The sponsor has 
established procedures in conformity with regulatory requirements worldwide to ensure 
appropriate reporting of PQC information; all studies conducted by the sponsor or its affiliates 
will be conducted in accordance with those procedures.

Procedures
All initial PQCs must be reported to the sponsor by the study-site personnel within 24 hours after 
being made aware of the event.
If the defect is combined with a serious adverse event, the study-site personnel must report the 
PQC to the sponsor according to the serious adverse event reporting timelines (refer to 
Section 12.3.2, Serious Adverse Events). A sample of the suspected product should be 
maintained for further investigation if requested by the sponsor.

Drug Accountability
The investigator is responsible for ensuring that all study drug received at the site is inventoried 
and accounted for throughout the study. The dispensing of study drug to the subject, and the 
return of study drug from the subject (if applicable), must be documented on the drug 
accountability form. Parents/legally acceptable representatives must be instructed to return all 
original containers, whether empty or containing study drug. The study drug administered to the 
subject must be documented on the drug accountability form. All study drug will be stored and 
disposed of according to the sponsor's instructions. Study-site personnel must not combine 
contents of the study drug containers.
Study drug must be handled in strict accordance with the protocol and the container label, and 
must be stored at the study site in a limited-access area or in a locked cabinet under appropriate 
environmental conditions. Unused study drug, and study drug returned by the subject’s parents or 
legally acceptable representatives, must be available for verification by the sponsor's study site 
monitor during on-site monitoring visits. The return to the sponsor of unused study drug, or used 
returned study drug for destruction, will be documented on the drug return form. When the study 
site is an authorized destruction unit and study drug supplies are destroyed on-site, this must also 
be documented on the drug return form.
Study drug should be dispensed under the supervision of the investigator or a qualified member 
of the study-site personnel, or by a hospital/clinic pharmacist. Study drug will be supplied only 
to parents/legally acceptable representatives of subjects participating in the study. Returned study 
drug must not be dispensed again, even to the same subject. Study drug may not be relabeled or 
reassigned for use by other subjects. The investigator agrees neither to dispense the study drug 
from, nor store it at, any site other than the study sites agreed upon with the sponsor.

ETHICAL ASPECTS
16.1.
Study-Specific Design Considerations
The primary ethical consideration in this study is the use of young pediatric subjects who have 
recently completed the Fontan procedure with a high thrombotic risk and for whom there is scant 
evidence-based information regarding thromboprophylaxis. There is limited data on the optimal 
use of thromboprophylaxis for these children and the data are primarily extrapolated from 
clinical studies in adults. None of the current standards of care (ASA or warfarin) appear to have 
been very successful at mitigating the risk and incidence of post-Fontan thrombosis according to 
the small amount of data from few clinical studies and the cumulative years of 
practice.12,11,23,20,18 Using ASA as the comparator in this study will allow a descriptive
comparison of results across 2 different drug classes: antiplatelet (ASA) versus anticoagulant 
(rivaroxaban, which has demonstrated effectiveness in the adult population as a 
thromboprophylaxis agent). In combination with extrapolation from adult efficacy data, this 
study could support an alternative treatment in this population by providing PK, PD, safety, and 
supportive efficacy data.
Therefore, this study aims to assess the safety and efficacy of a novel oral anticoagulant that has 
been extensively studied and has demonstrated safety and efficacy for the prevention and 
treatment of multiple thrombosis-mediated conditions in adults, and thus far has been well 
tolerated in pediatric subjects. The study is designed with sufficient scientific rigor to meet its 
objectives while having close oversight of an IDMC, in addition to the sponsor, to protect 
subjects from experiencing unacceptably high levels of risk of harm or suffering. Further, the 
study risk/benefit consideration will be addressed, and reviewed, by an independent ethics 
review board before the conduct of the study. Due to the limited availability of subjects in this 
study population and the expected low event rate, formal hypothesis testing of the primary 
efficacy endpoint is not feasible.
Parents/legally acceptable representatives of potential subjects will be fully informed of the risks 
and requirements of the study, and during the study they will be given any new information that 
may affect their decision to continue participation. Parents/legally acceptable representatives and 
subjects 7 to 8 years of age will be told that their consent/assent to participate in the study is 
voluntary and may be withdrawn at any time with no reason given and without penalty or loss of 
benefits to which they would otherwise be entitled. 
When referring to the signing of the ICF, the term legally acceptable representative refers to the 
legally appointed guardian of the child with authority to authorize participation in research. For 
each subject, his or her parent(s) (preferably both parents, if available) or a legally acceptable 
representative(s), as required by local regulations, must give written consent (permission)

Clinical Protocol 39039039CHD3001 - Amendment INT-2
67
Approved, Date: 27 July 2017
according to local requirements after the nature of the study has been fully explained and before 
the performance of any study-related assessments. Assent must be obtained from children (minors) 
capable of understanding the nature of the study, typically subjects 7 years of age and older, 
depending on the institutional policies. For the purposes of this study, all references to subjects 
who have provided consent (and assent as applicable) refer to the subjects and his or her parent(s) 
or the subject's legally acceptable representative(s) who have provided consent/assent according to 
this process. Minors who assent to a study and later withdraw that assent should not be maintained 
in the study against their will, even if their parents/legally acceptable representatives still want 
them to participate. 
Clinical Study with a New Study Drug 
Thorough scientific evaluation of any promising treatment before market authorization is an 
ethical requirement. In the continuing search for medications with improved efficacy and safety 
profiles, it is necessary to fully investigate and understand new products before public exposure. 
Full investigation and study of a new product must always include the study of pediatric subjects 
if there is any reasonable belief that the treatment will benefit the pediatric population.
Rivaroxaban has been proven to have a positive benefit-risk profile in multiple 
thrombosis-mediated conditions. This study is being conducted in pediatric subjects 2 to 8 years 
of age with single ventricle physiology who have completed the Fontan procedure within 
4 months prior to enrollment. The results of this study are expected to provide useful information 
on the PK, PK/PD, safety, and efficacy of rivaroxaban as well as the dosing guidelines for this 
pediatric patient population. 
The daily, cumulative, and total blood volume to be collected from each subject in this study is 
within the range of maximum allowances for pediatric research set by hospitals routinely 
participating in pediatric clinical studies.13 The total blood volume to be collected will be 
approximately 32.7 mL in Part A and 25 ml in Part B over a 12 month period (Attachment 1: 
Blood Volume). These estimates do not include any blood discarded due to blood drawing from 
peripheral or central lines, as these volumes may vary according to each site’s practice.
Safety of Dose 
This is the first clinical study with rivaroxaban in pediatric subjects after the Fontan procedure; a 
potential risk will be the actual exposure to study drug at the planned dose in the studied 
population being inconsistent with the estimated exposure based on PBPK modeling, which can 
lead to adverse events including bleeding events, or lack of efficacy. 
To ensure appropriate exposure to study drug, a staggered approach was chosen. In Part A of the 
study, in a small number of subjects, the single- and multiple-dose rivaroxaban PK will be 
evaluated as well as the initial safety and tolerability. The DRC will review the subject’s PK, PD,
and safety data obtained from the Initial PK, PD, and Safety Assessment Period prior to allowing 
the subject to continue on rivaroxaban therapy to complete the 12-month period.

Approved, Date: 27 July 2017
Enrollment and randomization into Part B of this study will only begin once the PK and safety 
results in the Initial PK, PD, and Safety Assessment Period for subjects in Part A are deemed 
acceptable by the IDMC.
Capacity to Provide Informed Consent
Only parent(s) (preferably both parents if available) or legally acceptable representative(s) who 
are fully able to understand the risks, benefits, potential adverse events, and alternatives to 
participation, will provide their consent voluntarily. Subjects 7 to 8 years of age may be asked 
for their voluntary assent; the investigator will determine each subject’s capacity to provide 
informed assent. 
Subjects of 7 to 8 years of age or their parents or legally acceptable representatives may 
withdraw their assent or consent, respectively at any time without having to give a reason. 
16.2.
Regulatory Ethics Compliance
16.2.1.
Investigator Responsibilities
The investigator is responsible for ensuring that the study is performed in accordance with the 
protocol, current ICH guidelines on Good Clinical Practice (GCP), and applicable regulatory and

Approved, Date: 27 July 2017
At the end of the study, the investigator (or sponsor where required) will notify the IEC/IRB 
about the study completion (if applicable, the notification will be submitted through the head of 
investigational institution).
16.2.3.
Informed Consent/Assent
Parents/legally acceptable representatives and subjects must give written consent/assent
according to local requirements after the nature of the study has been fully explained. The ICF(s) 
must be signed before performance of any study-related activity. The ICF(s) and assent form that 
is/are used must be approved by both the sponsor and by the reviewing IEC/IRB and be in a 
language that the subject can read and understand. The informed consent/assent should be in 
accordance with principles that originated in the Declaration of Helsinki, current ICH and GCP 
guidelines, applicable regulatory requirements, and sponsor policy.
Before enrollment in the study, the investigator or an authorized member of the study-site 
personnel must explain to parents/legally acceptable representatives of potential subjects and 
subjects the aims, methods, reasonably anticipated benefits, and potential hazards of the study,
and any discomfort participation in the study may entail. Subjects and parents/legally acceptable
representatives will be informed that their participation is voluntary and that they may withdraw 
consent/assent to participate at any time. They will be informed that choosing not to participate 
will not affect the care the subject will receive.  Finally, they will be told that the investigator 
will maintain a subject identification register for the purposes of long-term follow up if needed 
and that their records may be accessed by health authorities and authorized sponsor personnel
without violating the confidentiality of the subject, to the extent permitted by the applicable 
law(s) or regulations. By signing the ICF the parent/legally acceptable representative and 
subjects are authorizing such access, and agrees to allow his or her study physician to recontact 
the subject for the purpose of obtaining consent/assent for additional safety evaluations, if 
needed.
The parent/legally acceptable representative and subjects will be given sufficient time to read the 
ICF and the opportunity to ask questions. After this explanation and before entry into the study, 
consent/assent should be appropriately recorded by means of the subject's parent/legally 
acceptable representative’s personally dated signature. After having obtained the consent/assent, 
a copy of the ICF must be given to the parent/legally acceptable representative of the subject.
If the subject or legally acceptable representative is unable to read or write, an impartial witness 
should be present for the entire informed consent/assent process (which includes reading and 
explaining all written information) and should personally date and sign the ICF after the oral 
consent/assent of the subject or legally acceptable representative is obtained.
Children (minors) or subjects who are unable to comprehend the information provided can be 
enrolled only after obtaining consent/assent of a legally acceptable representative. Assent must 
be obtained from children (minors) capable of understanding the nature of the study, typically 
subjects 7 years of age and older, depending on the institutional policies. Written assent should 
be obtained from subjects who are able to write. After having obtained the assent, a copy of the

assent form must be given to the subject, and to the subject's parent and/or legally acceptable 
representative.
16.2.4.
Privacy of Personal Data
The collection and processing of personal data from subjects enrolled in this study will be 
limited to those data that are necessary to fulfill the objectives of the study.
These data must be collected and processed with adequate precautions to ensure confidentiality 
and compliance with applicable data privacy protection laws and regulations. Appropriate 
technical and organizational measures to protect the personal data against unauthorized 
disclosures or access, accidental or unlawful destruction, or accidental loss or alteration must be 
put in place. Sponsor personnel whose responsibilities require access to personal data agree to 
keep the identity of subjects confidential.
The informed consent/assent
obtained from the subject’s
parents/legally acceptable
representatives includes explicit consent/assent for the processing of personal data and for the 
investigator/institution to allow direct access to his or her original medical records (source 
data/documents) for study-related monitoring, audit, IEC/IRB review, and regulatory inspection. 
This consent/assent also addresses the transfer of the data to other entities and to other countries.
The subject’s parents/legally acceptable representatives have the right to request through the 
investigator access to his or her personal data and the right to request rectification of any data 
that are not correct or complete. Reasonable steps will be taken to respond to such a request, 
taking into consideration the nature of the request, the conditions of the study, and the applicable 
laws and regulations.
16.2.5.
Country Selection
This study will only be conducted in those countries where the intent is to launch or otherwise 
help ensure access to the developed product, unless explicitly addressed as a specific ethical 
consideration in Section 16.1, Study-Specific Design Considerations.
17.
ADMINISTRATIVE REQUIREMENTS
17.1.
Protocol Amendments
Neither the investigator nor the sponsor will modify this protocol without a formal amendment 
by the sponsor. All protocol amendments must be issued by the sponsor, and signed and dated by 
the investigator. Protocol amendments must not be implemented without prior IEC/IRB 
approval, or when the relevant competent authority has raised any grounds for non-acceptance, 
except when necessary to eliminate immediate hazards to the subjects, in which case the 
amendment must be promptly submitted to the IEC/IRB and relevant competent authority. 
Documentation of amendment approval by the investigator and IEC/IRB must be provided to the 
sponsor. When the change(s) involves only logistic or administrative aspects of the study, the 
IRB (and IEC where required) only needs to be notified.

Subject Identification, Enrollment, and Screening Logs
The investigator agrees to complete a subject identification and enrollment log to permit easy 
identification of each subject during and after the study. This document will be reviewed by the 
sponsor study-site contact for completeness.
The subject identification and enrollment log will be treated as confidential and will be filed by 
the investigator in the study file. To ensure subject confidentiality, no copy will be made. All 
reports and communications relating to the study will identify subjects by subject identification
and date of birth. In cases where the subject is not enrolled into the study, the date seen and date 
of birth will be used.
The investigator must also complete a subject screening log, which reports on all subjects who 
were seen to determine eligibility for inclusion in the study.
17.4.
Source Documentation
At a minimum, source documentations consistent in the type and level of detail with that 
commonly recorded at the study site as a basis for standard medical care, must be available for 
the following: subject identification, eligibility, and study identification; study discussion and 
date of signed informed consent/assent; dates of visits; results of safety and efficacy parameters 
as required by the protocol; record of all adverse events and follow-up of adverse events; 
concomitant medication; drug receipt/dispensing/return records; study drug administration 
information; and date of study completion and reason for early discontinuation of study drug or 
withdrawal from the study, if applicable. 
The author of an entry in the source documents should be identifiable.
Specific details required as source data for the study and source data collection methods will be 
reviewed with the investigator before the study and will be described in the monitoring 
guidelines (or other equivalent document).
Inclusion and exclusion criteria not requiring documented medical history must be verified at a 
minimum by parent/legally acceptable representative interview or other protocol required 
assessment (eg, physical examination, laboratory assessment) and documented in the source 
documents.

An electronic source system may be utilized, which contains data traditionally maintained in a 
hospital or clinic record to document medical care (eg, electronic source documents) as well as 
the clinical study-specific data fields as determined by the protocol. This data is electronically 
extracted for use by the sponsor. If the electronic source system is utilized, references made to 
the eCRF in the protocol include the electronic source system but information collected through 
the electronic source system may not be limited to that found in the eCRF. Data in this system 
may be considered source documentation.
17.5.
Case Report Form Completion
Case report forms are prepared and provided by the sponsor for each subject in electronic format.
All data relating to the study must be recorded in eCRF. All eCRF entries, corrections, and 
alterations must be made by the investigator or authorized study-site personnel. The investigator 
must verify that all data entries in the eCRF are accurate and correct.
Electronic data capture will be used for this study. The study data will be transcribed by study-
site personnel from the source documents onto an electronic eCRF, if applicable. Study-specific 
data will be transmitted in a secure manner to the sponsor.
Worksheets may be used for the capture of some data to facilitate completion of the eCRF. Any 
such worksheets will become part of the subject's source documentation. All data relating to the 
study must be recorded in eCRFs prepared by the sponsor. Data must be entered into eCRFs in 
English. The eCRF must be completed as soon as possible after a subject visit, and the forms 
should be available for review at the next scheduled monitoring visit.
The investigator must verify that all data entries in the eCRFs are accurate and correct.
All eCRF entries, corrections, and alterations must be made by the investigator or other 
authorized study-site personnel. If necessary, queries will be generated in the eDC tool. 
If necessary, queries will be generated in the eDC tool. If corrections to a eCRF are needed after 
the initial entry into the eCRF, this can be done either of the following ways:

Investigator and study site personnel can make corrections in the eDC tool at their own 
initiative or as a response to an auto query (generated by the eDC tool)

Sponsor or sponsor delegate can generate a query for resolution by the investigator and 
study-site personnel.

Data Quality Assurance/Quality Control
Steps to be taken to ensure the accuracy and reliability of data include the selection of qualified 
investigators and appropriate study sites, review of protocol procedures with the investigator and 
study-site personnel before the study, and periodic monitoring visits by the sponsor, and direct 
transmission of clinical laboratory data from a central laboratory into the sponsor's data base. 
Written instructions will be provided for collection, handling, storage, and shipment of samples. 
Guidelines for eCRF completion will be provided and reviewed with study-site personnel before 
the start of the study.
The sponsor will review eCRFs for accuracy and completeness during on-site monitoring visits 
and after transmission to the sponsor; any discrepancies will be resolved with the investigator or 
designee, as appropriate. After upload of the data into the study database they will be verified for 
accuracy and consistency with the data sources. 
17.7.
Record Retention
In compliance with the ICH/GCP guidelines, the investigator/institution will maintain all eCRFs 
and all source documents that support the data collected from each subject, as well as all study 
documents as specified in ICH/GCP Section 8, Essential Documents for the Conduct of a 
Clinical Trial, and all study documents as specified by the applicable regulatory requirement(s). 
The investigator/institution will take measures to prevent accidental or premature destruction of
these documents.
Essential documents must be retained until at least 2 years after the last approval of a marketing 
application in an ICH region and until there are no pending or contemplated marketing 
applications in an ICH region or until at least 2 years have elapsed since the formal 
discontinuation of clinical development of the investigational product. These documents will be 
retained for a longer period if required by the applicable regulatory requirements or by an 
agreement with the sponsor. It is the responsibility of the sponsor to inform the 
investigator/institution as to when these documents no longer need to be retained.
If the responsible investigator retires, relocates, or for other reasons withdraws from the 
responsibility of keeping the study records, custody must be transferred to a person who will 
accept the responsibility. The sponsor must be notified in writing of the name and address of the 
new custodian. Under no circumstance shall the investigator relocate or dispose of any study 
documents before having obtained written approval from the sponsor.
If it becomes necessary for the sponsor or the appropriate regulatory authority to review any 
documentation relating to this study, the investigator/institution must permit access to such 
reports.

17.8.
Monitoring
The sponsor will use a combination of monitoring techniques, central, remote, or on-site 
monitoring, to monitor this study.  The sponsor will perform on-site monitoring visits as 
frequently as necessary. The monitor will record dates of the visits in a study site visit log that 
will be kept at the study site. The first post-initiation visit will be made as soon as possible after 
enrollment has begun. At these visits, the monitor will compare data entered into the eCRFs with 
the source documents (eg, hospital/clinic/physician’s office medical records); a sample may be 
reviewed. The nature and location of all source documents will be identified to ensure that all 
sources of original data required to complete the eCRF are known to the sponsor and study-site 
personnel and are accessible for verification by the sponsor study-site contact. If electronic 
records are maintained at the study site, the method of verification must be discussed with the 
study-site personnel. 
Direct access to source documents (medical records) must be allowed for the purpose of 
verifying that the recorded data are consistent with the original source data. Findings from this 
review will be discussed with the study-site personnel. The sponsor expects that, during
monitoring visits, the relevant study-site personnel will be available, the source documents will
be accessible, and a suitable environment will be provided for review of study-related 
documents. The monitor will meet with the investigator on a regular basis during the study to 
provide feedback on the study conduct.
In addition to on-site monitoring visits, remote contacts can occur. It is expected that during 
these remote contacts, study-site personnel will be available to provide an update on the progress 
of the study at the site.  Central monitoring will take place for data identified by the sponsor as 
requiring central review.
17.9.
Study Completion/Termination
17.9.1.
Study Completion/End of Study
The study is considered completed with the last scheduled study contact shown in the Time and 
Events Schedule for the last subject participating in the study. The final data from the study site 
will be sent to the sponsor (or designee) after completion of the final subject study contact at that 
study site, in the time frame specified in the Clinical Trial Agreement.
17.9.2.
Study Termination
The sponsor 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.

Approved, Date: 27 July 2017
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 IEC/IRB or 
local health authorities, the sponsor's procedures, or GCP guidelines

Inadequate recruitment of subjects by the investigator

Discontinuation of further study drug development
17.10. On-Site Audits
Representatives of the sponsor's clinical quality assurance department may visit the study site at 
any time during or after completion of the study to conduct an audit of the study in compliance 
with regulatory guidelines and company policy. These audits will require access to all study 
records, including source documents, for inspection. Subject privacy must, however, be 
respected. The investigator and study-site personnel are responsible for being present and 
available for consultation during routinely scheduled study-site audit visits conducted by the 
sponsor or its designees. 
Similar auditing procedures may also be conducted by agents of any regulatory body, either as 
part of a national GCP compliance program or to review the results of this study in support of a 
regulatory submission. The investigator should immediately notify the sponsor if he or she has
been contacted by a regulatory agency concerning an upcoming inspection.
17.11. Use of Information and Publication
All information, including but not limited to information regarding rivaroxaban or the sponsor's 
operations (eg, patent application, formulas, manufacturing processes, basic scientific data, prior 
clinical data, formulation information) supplied by the sponsor to the investigator and not 
previously published, and any data, including research data, generated as a result of this study, 
are considered confidential and remain the sole property of the sponsor. The investigator agrees 
to maintain this information in confidence and use this information only to accomplish this 
study, and will not use it for other purposes without the sponsor's prior written consent.
The investigator understands that the information developed in the study will be used by the 
sponsor in connection with the continued development of rivaroxaban, and thus may be disclosed 
as required to other clinical investigators or regulatory agencies. To permit the information 
derived from the clinical studies to be used, the investigator is obligated to provide the sponsor 
with all data obtained in the study.
The results of the study will be reported in a Clinical Study Report generated by the sponsor and 
will contain data from all study sites that participated in the study as per protocol. Recruitment 
performance or specific expertise related to the nature and the key assessment parameters of the
study will be used to determine a coordinating investigator. Results of analyses performed after

Approved, Date: 27 July 2017
the Clinical Study Report has been issued will be reported in a separate report and will not 
require a revision of the Clinical Study Report. Study subject identifiers will not be used in 
publication of results. Any work created in connection with performance of the study and 
contained in the data that can benefit from copyright protection (except any publication by the 
investigator as provided for below) shall be the property of the sponsor as author and owner of 
copyright in such work.
Consistent with Good Publication Practices and International Committee of Medical Journal 
Editors guidelines, the sponsor shall have the right to publish such primary (multicenter) data 
and information without approval from the investigator. The investigator has the right to publish 
study site-specific data after the primary data are published. If an investigator wishes to publish 
information from the study, a copy of the manuscript must be provided to the sponsor for review 
at least 60 days before submission for publication or presentation. Expedited reviews will be 
arranged for abstracts, poster presentations, or other materials. If requested by the sponsor in 
writing, the investigator will withhold such publication for up to an additional 60 days to allow 
for filing of a patent application. In the event that issues arise regarding scientific integrity or 
regulatory compliance, the sponsor will review these issues with the investigator. The sponsor 
will not mandate modifications to scientific content and does not have the right to suppress 
information. For multicenter study designs and substudy approaches, secondary results generally 
should not be published before the primary endpoints of a study have been published. Similarly, 
investigators will recognize the integrity of a multicenter study by not submitting for publication 
data derived from the individual study site until the combined results from the completed study
have been submitted for publication, within 12 months of the availability of the final data (tables, 
listings, graphs), or the sponsor confirms there will be no multicenter study publication. 
Authorship of publications resulting from this study will be based on the guidelines on 
authorship, such as those described in the Uniform Requirements for Manuscripts Submitted to 
Biomedical Journals, which state that the named authors must have made a significant 
contribution to the design of the study or analysis and interpretation of the data, provided critical 
review of the paper, and given final approval of the final version.
Registration of Clinical Studies and Disclosure of Results
The sponsor will register and disclose the existence of and the results of clinical studies as 
required by law.

Manual for further details)
Status Post Fontan Operation
Inclusion: Patient having undergone a Fontan operation. This operation has been performed with various 
surgical modifications including: 1) direct anastomosis of the right atrium to the pulmonary artery; 2) 
valved or non-valved conduit from right atrium to right ventricle; 3) classic Glenn shunt (superior vena 
cava to transected right pulmonary artery) and conduit from inferior vena cava to left pulmonary artery; 4) 
bidirectional Glenn shunt plus intra-atrial conduit connection from the inferior vena cava to the right 
pulmonary artery; 5) bidirectional Glenn shunt plus extracardiac conduit connection from the  inferior 
vena cava to the main pulmonary artery. Optimal evaluation of the Fontan is achieved by knowledge 
of the specific type of connection that was performed. The individual performing the examination 
must find out the details of the operation before the examination.
Blood pressure in arm and leg if status post Norwood or arch reconstruction.
Full examination of anatomy using 2D, color and spectral Doppler and 3-D evaluation when indicated. 
Particular attention should be given to the following:

Attachment 3: Estimated glomerular filtration rate (eGFR)

The original Schwartz formula: If serum creatinine (SCr) is measured with routine methods 
that have not been recalibrated to be traceable to isotope dilution mass spectrometry (IDMS) 
(eg, the traditional Jaffé reaction), the estimated glomerular filtration rate (eGFR) should be 
obtained from the original Schwartz formula:28
eGFR (mL/min/1.73 m2) = k * height (cm) / SCr g/dL) where k is proportionality constant:
k = 0.55 in children up to 13 years

The updated Schwartz formula: If SCr is measured by an enzymatic creatinine method that 
has been calibrated to be traceable to IDMS, the updated Schwartz formula should be used 
to obtain the eGFR:29
eGFR (mL/min/1.73 m2) = 0.413 * height (cm) / SCr mg/dL
The National Kidney Disease Education Program website
(http://www.nkdep.nih.gov/professionals/gfr_calculators/index.htm) offers electronic calculators 
of eGFR in the pediatric population based on the updated Schwartz formula. Serum creatinine in 
micromoles per liter, the value should be multiplied by 88.4 (1 mg/dL = 88.4 umol/L).
