Filter by:The investigators intend to screen for new donors, given that there may a donor effect (PubMed ID: 25857665), with some donors not inducing remission in any patient whilst others inducing remission in 20-40% of cases. It is important to give UC patients participating in RCTs stool that has been demonstrated to be effective in some patients. We therefore propose to conduct an open label study in patients with active UC to ensure new donors are effective at inducing remission in some patients. Patients that have FMT will relapse within 18 months (PubMed ID: 25857665) although further FMT therapy induces remission so it is possible that maintenance FMT will result in long term remission, but this needs evaluation. We will therefore follow UC patients that have responded to FMT long term in this open label study.
This is a Phase 2b, multi-centered, randomized, placebo-controlled trial with treatment phase over 24 weeks. Ulcerative Colitis (UC) is a condition that causes inflammation and ulceration of the inner lining of the rectum and colon (the large bowel). In UC, ulcers develop on the surface of the lining and these may bleed and produce mucus. Individuals with UC can become very unwell with disabling bloody diarrhoea, uncontrollable bowel habit and profound tiredness. In very severe cases, UC carry the risks of rupture of the inflamed bowel wall requiring an emergency operation to remove the colon. The MARVEL study investigates whether MitoQ is a beneficial drug treatment for UC. Earlier studies have shown that the inflamed UC gut lining releases 'danger signals' arising from the mitochondria. These 'danger signals' attract immune cells and make inflammation worse. Mitochondria are the 'batteries' or 'power stations' that reside within, and provide energy for living cells. In the gut lining of individuals with UC, the mitochondria are more prone to damage that increases the release of these danger signals. MitoQ protects the mitochondria and exerts an anti-inflammatory effect. The investigators hypothesise that MitoQ will improve UC and allow the bowels to heal properly following a disease flare. In the MARVEL study, individuals with an active flare of UC requiring standard oral Prednisolone will be given either MitoQ or placebo as a daily capsule for 24 weeks. The Investigators will carry out an assessment after 12 and 24 weeks to find out if MitoQ will result in higher rates of improvement in the participants' symptoms and gut lining inflammation. Furthermore, the investigators 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 MARVEL study will be the first study in UC. 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. If the MARVEL study provides supportive data, MitoQ can be a safe and cost-effective new treatment that works at blocking the specific inflammatory signal found in the gut lining of individuals with UC.
