Non Inferiority KawasakI Trial With Anakinra

Официальное название

A Randomized, Controlled, Open-label, Non Inferiority KawasakI Trial With Anakinra

Обзор

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.

Подробное описание

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

• less than 5 days of fever but all 5 clinical criteria above
• incomplete KD cases defined as:

• children/adolescents (>1 year old) with fever greater than or equal to 5 days AND at least 2 other compatible clinical criteria as listed above;
• OR infants ≤ 1 year old with fever greater than or equal to 7 days without other explanation;

AND for both age groups, CRP ≥30 mg/L or erythrocyte sedimentation rate (ESR) ≥40 mm/hr (or both) AND for both age groups EITHER the presence of any 3 or more of: anaemia for age (haemoglobin < lower limit of normal reference range for local laboratory); platelet count ≥450,000/L or <140,000/L; albumin <30 g/L; elevated ALT (> upper limit of normal reference range for local laboratory); white cell count ≥15,000/L; urine ≥10 white blood cells per high power field iv.

OR abnormal echocardiogram compatible with KD but without established CAA, with ≥ 3 of the following suggestive features: decreased left ventricular function, mitral regurgitation, pericardial effusion, or dilated but non-aneurysmal coronary arteries (internal diameter 2≤Z<2.5; and not meeting the exclusion criteria for aneurysmal change as defined below).

• To be enrolled children need to show persistent fever ≤7 days

Критерии исключения

• Clinical picture consistent with Kawasaki Shock Syndrome (KDSS) or Macrophage Activation Syndrome (MAS) OR Multisystem Inflammatory Syndrome in Children (MIS-C)
• History or evidence of any previous heart disease
• Known hypersensitivity to anakinra, IVIG and ASA or any medical condition that contraindicates the use of these treatments
• Patients with KD receiving IVIG, corticosteroids, immunosuppressants, biologic treatments at the time of screening
