Summary

The Purpose of this study is to characterize the single and multiple-dose pharmacokinetic (PK) and pharmacokinetic/pharmacodynamic (PK/ PD) profiles after oral rivaroxaban therapy administered to pediatric participants 2 to 8 years of age with single ventricle physiology who have completed the Fontan procedure within 4 months prior to enrollment (Part A) and to evaluate the safety and efficacy of rivaroxaban, administered twice daily (exposure matched to rivaroxaban 10 milligram \[mg\] once daily in adults) compared to acetylsalicylic acid (ASA), given once daily (approximately 5 milligram per kilogram \[mg/kg\]) for thromboprophylaxis in pediatric participants 2 to 8 years of age with single ventricle physiology who have completed the Fontan procedure within 4 months prior to enrollment.
