Mini-MARVEL - Mitochondrial Antioxidant Therapy in Ulcerative Colitis — Mini-MARVEL  

Ulcerative Colitis Clinical Trial

Official title:
Mitochondrial Antioxidant Therapy to Resolve Inflammation in Ulcerative Colitis (Mini-MARVEL): A Phase 2b Feasibility Randomised Placebo Controlled Trial of Oral MitoQ in Mild-tomoderately Active Paediatric UC

Clinical Trial Summary

Mini-MARVEL study, children and young people with an active flare of UC requiring either the start of or an increase in existing mesalazine therapy will be given either MitoQ or placebo as a daily capsule for 24 weeks in the Mini-MARVEL M arm of the study. Those children and young people with an active flare of UC requiring the start of an oral steroid course will be given either MitoQ or placebo as a daily capsule for 24 weeks in the Mini- MARVEL S arm of the study, Further, newly diagnosed children and young people with UC can have either MitoQ or placebo as a daily capsule for 24 weeks with their newly started mesalazine therapy in the Mini-MARVEL M arm of the study, or with their newly started oral steroid course in the Mini-MARVEL S arm of the study. This trial will look at how feasible a multi-centre stratified RCT of this add-on (adjunct) therapy in paediatric UC is in the UK. An assessment after 6, 12 and 24 weeks will be carried out to find out if MitoQ will result in higher rates of improvement in the participants' symptoms, quality of life and gut lining inflammation. Furthermore, the trial will investigate if their UC will be better controlled and that they are less likely to need further steroids or more potent forms of drugs. MitoQ has been shown to be safe in 2 large human clinical studies in Parkinson's disease and Hepatitis C, but the Mini-MARVEL study, starting alongside the adult MARVEL study, will be the first study in UC in children and young people. At low doses, MitoQ is used as a nutritional supplement that has an anti-oxidant effect. Currently, many drug treatments in UC are very strong, expensive and aimed at suppressing the immune system. Steroid courses are often needed but these have lots of adverse events in children and young people and are strongly disliked by many. If the Mini- MARVEL study provides supportive data on feasibility, including where we have to concentrate our efforts to include enough children and young people through to study end, we could design a full-scale trial to see if MitoQ can be a safe and cost-effective new treatment that works at blocking the specific inflammatory signal found in the gut lining of children and young people with UC.
