Participants will receive oral suspension containing rivaroxaban 1 milligram per milliliter (mg/ml) twice daily in Part A and Part B. Following total daily doses of Rivaroxaban will be administered based on the weight of the participants: 7 to <8 kilogram (kg) will receive 2.2 milligram (mg); 8 to <10 kg will receive 3.2 mg; 10 to<12 kg will receive 3.4 mg; 12 to <20 will receive 4.0 mg and 20 to <30 will receive 5.0 mg.
|Experimental: Acetylsalicylic Acid||
Drug: Acetylsalicylic Acid
Participants will receive 5 milligram per kilogram (mg/kg) of acetylsalicylic acid once daily up to 12 months in Part B.
- Maximum Observed Plasma Concentration (Cmax) [ Time Frame: Up to Month 12 ]The Cmax is the maximum observed Plasma concentration.
- Area Under the Analyte ConcentrationTime Curve From Time 0 to 24 Hours (AUC24) [ Time Frame: Up to Month 12 ]The AUC24 is the area under the plasma concentration-time curve from time 0 to 24 hours.
- Maximum Plasma Concentration (Cmax,ss) at Steady State [ Time Frame: Up to Month 12 ]The Cmax,ss is the maximum observed plasma concentration at steady state.
- Minimum Plasma Concentration (Cmin,ss) at Steady State [ Time Frame: Up to Month 12 ]The Cmin,ss is the minimum observed plasma concentration at steady state.
- Absolute Prothrombin Time (PT) [ Time Frame: Up to Month 12 ]Absolute prothrombin time (PT) will be assessed as pharmacodynamic parameter.
- Activated Partial Thromboplastin Time (aPTT) [ Time Frame: Up to Month 12 ]Activated partial thromboplastin time (aPTT) will be assessed as pharmacodynamic parameter.
- Anti-Factor Xa (FXa) [ Time Frame: Up to Month 12 ]Anti-factor Xa (FXa) will be assessed as pharmacodynamic parameter.
- Number of Participants With Major Bleeding Events [ Time Frame: Up to Month 12 ]Major bleeding is defined as overt bleeding and associated with a fall in hemoglobin of 2 gram per deciliter (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.
- Number of Participants With Incidence of Thrombotic Events [ Time Frame: Up to Month 12 ]Thrombotic event is 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).
- Number of Participants With Adverse Events as a Measure of Safety and Tolerability [ Time Frame: For the duration of the study, average 13 months ]
- Number of Participants With Clinically Relevant Non-Major Bleeding Events [ Time Frame: Up to Month 12 ]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).
- Number of Participants With Trivial (Minimal) Bleeding [ Time Frame: Up to Month 12 ]Trivial (minimal) bleeding is defined as any other overt bleeding event that does not meet criteria for clinically relevant non major bleeding.
