Non Inferiority KawasakI Trial With Anakinra

Phase 4
Not yet recruiting
Conditions
Kawasaki Disease
Anakinra
Interventions
Drug: Intravenous Immunoglobulins, Human
Registration Number
NCT06697431
Lead Sponsor
Meyer Children's Hospital IRCCS
Brief Summary

This is a multicenter, open-label, randomized, controlled, interventional trial followed by a long-term observational extension period in patients with Kawasaki Disease (KD) to be treated eitherwith endovenous Immunoglobulins (IVIG-standard treatment) versus anakinra

Aim of the study: to demonstrate that anakinra is non-inferior to IVIG in KD, in terms of fever control in the acute phase and development of coronary artery dilation/aneurisms (CAA) within one year from the onset.

Detailed Description

This is a multicenter national, open label, randomized, controlled, interventional trial followed by a long-term observational extension period. This is a non-inferiority study Patients who fulfill the eligibility criteria and whose parent/carer (legal representative) has provided informed consent will be randomized 1:1 to receive either

1. IVIG 2g/kg administered in 10-12 hours as per local standard of care (standard treatment) OR

2. Anakinra 2mg/kg intravenously, max 100 mg/dose 4 times/day (investigational treatment)

PLUS Aspirin (ASA) 50mg/kg QID until 36 hours from fever disappearance, then switched to low-dose (3-5 mg/Kg once a day) as per standard of care

Primary Outcome Measures
NameTimeMethod
Number of patients with treatment response in both treatment arms12 months

Response rate

Number of patients with CAA (as per Z-scores) at the end of the study period in both treatment arms12 months

CAA rate in both arms. CAAs will be classified in accordance with the scheme based on Z scores proposed by AHA. No coronary involvement with Z score \<2, dilation only with Z score \> 2 to \<2.5 or if initially \<2 with a decrease during follow-up ≥1 3, small aneurysm with Z score ≥2.5 to \<5, medium aneurysm with Z score ≥5 to \<10 and absolute dimension \<8 mm and large or giant aneurysm with Z score ≥10, or absolute dimension ≥8 mm
