Narrative objectives1 The objective of this randomized comparative study is to verify whether immunoglobulin (IVIG) + cyclosporin A (CsA) combination therapy as the primary treatment is superior to the standard IVIG treatment in preventing the development of coronary artery abnormalities (CAAs) in pediatric patients with severe Kawasaki disease (KD).

Primary outcomes Frequency of CAAs during the study period (central review of echocardiography data)
Key secondary outcomes [Efficacy]

Key inclusion criteria 1)Pediatric patients with a diagnosis of KD according to the Kawasaki Disease Diagnostic Guideline (the 5th revised edition).
Patients who meet 5 of the 6 main symptoms below are diagnosed as having KD.
2)Severe KD patients with a risk score of 5 points or higher.
The risk score is defined as the sum of all items in the risk-scoring system (5 blood exam data, 2 demographic data of the subjects) developed by Kobayashi et al. Of note, the risk scoring will be performed using a method employed in the previous literature in which the worst values of the blood exam obtained within the acceptable range of time points will be adopted.
3)Age of 4 months or more at the time of signing the informed consent form.
4)Inclusion in the study within 7 days of disease onset. (considering day 1 to be the day when the fever develops.)
5)Informed consent form signed by the patient or a legal guardian.
Key exclusion criteria 1)A history of KD recurrence.
2)CAAs prior to enrolment.
3)No presence of fever prior to enrolment.
4)Suspicion that the symptoms may correspond to a disease other than KD. (haemolytic streptococcal infection, EB virus infection, Yersinia infection, measles or Stevens-Johnson syndrome.)
5)Initiation of IVIG treatment later than 9 days after disease onset.
6)Administration of IVIG within 180 days prior to obtaining informed consent.
7)Treatment with steroids (except external preparations), steroid pulse, biological agents, neutrophil elastase inhibitors, immunosuppressants, or plasmapheresis within 30 days of screening.
8)History of hypersensitivity to CsA preparations, immunoglobulin preparations, or aspirin.
9)Having had treatment with tacrolimus, pitavastatin, rosuvastatin, bosentan, aliskiren, asunaprevir or vaniprevir.
10)Aspartate aminotransferase or, alanine aminotransferase values of 500 IU/L or higher.
11)An estimated glomerular filtration rate of 50 mL/min/1.73 m2 or lower.
12)Presence of an active bacterial infection: septicaemia, meningitis purulenta, peritonitis or bacterial pneumonia.
13)Treatment with other investigational drugs within 12 weeks of study commencement.
14)Others: patients who are judged to be inappropriate for participants of the clinical study for safety reasons by the investigators or the sub-investigators.
