Primary Outcome(s)

Main Objective: The primary efficacy objective is: To assess the incidence of symptomatic recurrent venous thromboembolism

The principal safety objective is: ? To assess the incidence of overt major and clinically relevant non-major bleeding.

Primary end point(s): 1. Efficacy: The composite of all symptomatic recurrent venous thromboembolism

2. Safety: The composite of overt major and clinically relevant non-major bleeding.

Secondary Objective: The secondary efficacy objective is: To assess the incidence of symptomatic recurrent venous thromboembolism and asymptomatic deterioration on repeat imaging.
An additional objective is: To characterize the pharmacokinetic / pharmacodynamics profile of rivaroxaban.

Timepoint(s) of evaluation of this end point: 1. After 90 days of treatment and again at 30 days post treatment

2. After 90 days of treatment and again at 30 days post treatment

Secondary Outcome(s)

Secondary end point(s): 1. The composite of all symptomatic recurrent venous thromboembolism and asymptomatic deterioration on repeat imaging.

2. Results of pharmacokinetics (PK)/ pharmacodynamics (PD) analyses

Timepoint(s) of evaluation of this end point: 1. After 90 days of treatment and again at 30 days post treatment

2. PK and PD as defined in the protocol
