Rivaroxaban for Children Aged Over 2 Years With Giant Coronary Artery Aneurysms After Kawasaki Disease
Rivaroxaban Versus Warfarin for Thromboprophylaxis in Children Aged Over 2 Years With Giant Coronary Artery Aneurysms After Kawasaki Disease: a Multicenter, Open-label, Parallel, Exploratory, Randomized Controlled Trial
Source: ClinicalTrials.gov · Last updated 6 Jul 2026
Brief summary (registry, in English)
Based on population pharmacokinetic model-based simulation, a 15 mg-equivalent, age-, and bodyweight-adjusted dosing regimen for Chinese children with giant coronary artery aneurysms after acute Kawasaki disease was proposed. This exploratory trial aims to evaluate the feasibility, safety and effectiveness of rivaroxaban compared to warfarin for thromboprophylaxis in children aged over 2 years with giant coronary artery aneurysms after Kawasaki disease

Copied verbatim from ClinicalTrials.gov and grouped by topic. Only the trial team decides who can take part.
Prior treatment
- Thrombus within giant coronary aneurysm was confirmed by previous imaging examinations, including two-dimensional echocardiography, computed tomography angiography in coronary artery or coronary angiography
- Concomitant use of strong inhibitors of both CYP3A4 and P-glycoprotein, including but not limited to all human immunodeficiency virus protease inhibitors and the following azole-antimycotics agents: ketoconazole, itraconazole, voriconazole, posaconazole, if used systemically (fluconazole is allowed)
- Concomitant use of strong inducers of CYP3A4, including but not limited to rifampicin, rifabutin, phenobarbital, phenytoin and carbamazepine
Other illness
- Active bleeding or bleeding risk contraindicating anticoagulant therapy
- With history of venous thromboembolism or risk factors related with venous thromboembolism, like congenital heart disease, carcinoma, central venous catheter or long-term immobilization.
- Hypersensitivity or any other contraindications listed in the local labeling for the comparator treatment or experimental treatment
Lab values
- An eGFR \<30mL/min/1.73 m2 (For children younger than 1 year, serum creatinine results above 97.5th percentile)
- Platelet count \< 100 x 109/L
- Hepatic disease which is associated with either: coagulopathy leading to a clinically relevant bleeding risk, or alanine aminotransferase \> 5x ULN or total bilirubin \> 2x ULN with direct bilirubin \> 20% of the total
