Randomised Evaluation of COVID-19 Therapy (RECOVERY) in Children With PIMS-TS in Switzerland (SWISSPED-RECOVERY)

In May 2020 a new COVID-associated inflammatory syndrome in children was identified, Paediatric Inflammatory Multisystem Syndrome - Temporally associated with SARS-CoV-2 (PIMS-TS). A rapid international consensus process identified the need to evaluate corticosteroids and intravenous immunoglobulin (IVIg) as initial therapies in PIMS-TS, and confirmed tocilizumab and anakinra as biological anti-inflammatory agents to be evaluated as a second line therapy. This Swissped-Recovery trial is a sister trial to the RECOVERY international trial with the implementation of the study at Swiss study sites. The protocol describes an overarching trial design to provide reliable evidence on the efficacy of candidate therapies for children hospitalised with PIMS-TS. It is an adaptive pragmatic platform trial with an open-label randomisation. New trial arms can be added as evidence emerges that other candidate therapeutics should be evaluated. Additional substudies can be added to provide more detailed information on side effects or sub-categorisation of patient types.
