Pharmacometrics Analysis of Rivaroxaban in Chinese Children Aged Over 2 Years

Summary

Based on an established Kawasaki disease cohort database, this prospective, single-center, single-arm, observational study will collect clinical data from children aged 2 years and older with giant coronary artery aneurysms after Kawasaki disease who received rivaroxaban treatment. Rivaroxaban plasma concentrations, anti-factor Xa activity levels, and genetic polymorphisms will be measured and analyzed to support the population pharmacokinetic/pharmacodynamic analysis
