Kawasaki Disease Giant Coronary Artery Aneurysm Rivaroxaban Warfarin Anticoagulation

ClinConnect Summary

Lifelong anticoagulant treatment is required in children with giant coronary artery aneurysm after Kawasaki disease, imposing social and psychologic burdens on patients and parents. Rivaroxaban is a potential oral anticoagulant in this population. Considering the impact of ethnic difference and growth development, we proposed a Chinese-specific, optimized dosing regimen based on model- and clinical evidence-informed precision dosing.

This study is a multicenter, open-label, exploratory, randomized controlled trial to evaluate the feasibility, safety and effectiveness of rivaroxaban for thr...
