What this Trial Is About

Based on a population pharmacokinetic model-based dose optimization study, a 15 mg-equivalent, age-, and bodyweight-adjusted dosing regimen for Chinese children with giant coronary artery aneurysms after Kawasaki disease was proposed. This single-center, single-arm, pilot study aims to evaluate the feasibility of the 15 mg-equivalent dosing regimen within a limited sample size. Patients will be followed for more than 6 months. Clinical outcomes, including coronary artery thrombosis, major adverse cardiovascular events, and bleeding events, will be recorded. Rivaroxaban levels will be measured to assess the robustness of the model-informed dose optimization.
