Study & Design

Study Type: Interventional clinical trial of medicinal product

Study Design: Not specified

Primary Outcome Measures

Name	Time	Method
Main Objective: •To characterize the pharmacokinetic profile of rivaroxaban administered as dry powder for suspension;Secondary Objective: •To document safety and tolerability in terms of AEs observed after administration of the rivaroxaban dry powder for suspension formulation;Primary end point(s): The primary variables for pharmacokinetics will be the standard pharmacokinetic (PK) parameters for exposure, area under the curve (AUC) and Cmax, derived via population PK approaches. ;Timepoint(s) of evaluation of this end point: After at least 6 children and end of study

Secondary Outcome Measures

Name	Time	Method
Secondary end point(s): The principal safety outcome is the composite of major bleeding and clinically relevant non-major bleeding.;Timepoint(s) of evaluation of this end point: After any incident, after 6 children and at the end of the trial
