Mitochondrial Antioxidant therapy to Resolve Inflammation in Ulcerative Colitis (Mini-MARVEL): A Phase 2b feasibility randomised placebo controlled trial of oral MitoQ in mild-to-moderately active paediatric UC. Mini-MARVEL aims to assess the acceptability and practicality of delivering the intervention (MitoQ or placebo as add-on therapy) in a multi-centre UK placebo-controlled RCT in paediatric UC, and to estimate parameters for a possible larger study of this add-on therapy to conventional medical therapy in a multi-centre RCT. We will also obtain information on possible effectiveness of the repurposed drug MitoQ as an add-on to standard therapy compared to placebo add-on in mild-moderately active paediatric UC, to investigate effectiveness, safety and tolerability of MitoQ in UC, and also the effect on steroid burden and quality of life (QoL).
