Primary Outcome Measures
NameTimeMethod
Main Objective: The primary efficacy objective is: To assess the incidence of symptomatic recurrent venous thromboembolism<br><br>The principal safety objective is: ? To assess the incidence 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.<br>An additional objective is: To characterize the pharmacokinetic / pharmacodynamics profile of rivaroxaban.;Primary end point(s): 1. Efficacy: The composite of all symptomatic recurrent venous thromboembolism<br><br>2. Safety: The composite of overt major and clinically relevant non-major bleeding.;Timepoint(s) of evaluation of this end point: 1. After 90 days of treatment and again at 30 days post treatment<br><br>2. After 90 days of treatment and again at 30 days post treatment<br>
