Endpoints

Primary and secondary outcome measures (English text)

Primary endpoints 1

  1. The main criterion-evaluating efficacy in both groups is: the patient must reach a body (axillary (+0.5°C), tympanic, oral) temperature <38˚C within 2 days after initiation of treatment (considering time of the last escalation dose if any) (i.e. a binary outcome: success/failure).

Secondary endpoints 6

  1. Temperature <38˚C within 3 days (72h) after initiation of treatment
  2. Decrease of the CRP values from baseline to day 30 (CRP<6 mg/L at day 30)
  3. Reduction in physician assessment of disease activity, on a 10 points scale, of at least to 50% between baseline and day 14.
  4. Reduction in patient’s parent’s assessment of disease activity, on a 10 points scale, of to at least 50% between baseline and day 14.
  5. Resolution of coronary abnormalities; i.e worst Z score <2.5, by echocardiogram if present at day 45.
  6. Adverse events: pain/redness at injection site, bacterial infection, hepatitis, macrophage activation syndrome, severe neutropenia,

Reason
Safety related (clinical or pre-clinical results), Sponsor decision
Explanation
An urgent safety measure was implemented following a safety alert issued by the French Pediatric Society regarding the risks of giant aneurysms in infants under 6 months of age. This alert, in addition to warning about these misleading forms, reiterates the need to administer solumedrol at 2 mg/kg as a first-line treatment in addition to IVIG and to adhere to the PNDS recommendations.
Follow-up measures
the sponsor took the urgent safety measure of:
- suspending inclusion on 21-Oct-2025 (blocking the eCRF) and notifying the centers of this suspension by email on 21-Oct-2025.
- modify the inclusion criterion concerning the age of eligible patients in order to exclude the population most at risk (infants under 6 months).
