Description

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.

Official 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

Details

Part A: This part includes a 12-day Initial PK, PD, and Safety Assessment Period. Participants 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. 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 phone contact. Part B: Participants will be randomly assigned to two treatment groups and randomization ratio will be 2:1 for rivaroxaban and ASA. ASA will be used as control. There will be an up to a 21-day Screening Period, a 12 month Open-Label Treatment Period and a 30-day Follow-Up phone contact.
