All Clinical Trials in United Kingdom

Breath and sweat samples will be collected from people who have been admitted to hospital after a potential seizure and analysed by the team. The researchers then hope to identify a pattern of small molecules that can distinguish seizures from other events, and perhaps determine the severity of the seizure. Read Less

The aim of this study is to develop techniques for non-invasive imaging of biology in participants with benign or malignant renal masses based on the novel scanning MRI techniques, including recently invented Hyperpolarised MRI, deuterium metabolic imaging and sodium MRI. This imaging study will: 1) acquire imaging data from human tissues following the injection of hyperpolarised 13C pyruvate and use 13C-MRI to monitor changes in the ratio of 13C-lactate to 13C-pyruvate; 2) acquire imaging data from human tissues using Sodium MRI or 3) acquire imaging data from human tissues following the oral consumable of deuterated glucose. Data acquired during this physiological study will be used to optimise future imaging protocols.In the UK and possibly in other countries, there are some patients with renal masses that are over treated or undergo unnecessary procedures such as surgery or biopsies, as they are thought to have a malignant tumour or a more aggressive tumour but after the procedure it is found that the mass was benign. The aim of this study is to determine whether one or all of these imaging techniques can differentiate between benign and malignant renal masses with the view to developing the techniques further and hopefully reducing the need for over treatment or unnecessary procedures in patients with benign masses.

Polycystic ovary syndrome (PCOS) affects 10% of all women and usually presents with irregular menstrual periods and difficulties conceiving. However, PCOS is also a lifelong metabolic disorder and affected women have an increased risk of type 2 diabetes, high blood pressure, and heart disease. Increased blood levels of male hormones, also termed androgens, are found in most PCOS patients. Androgen excess appears to impair the ability of the body to respond to the sugar-regulating hormone insulin (=insulin resistance). The investigator has found that fat tissue of PCOS patients overproduces androgens and that this can result in a build-up of toxic fat, which increases insulin resistance and could cause liver damage. In a large cohort of women registered in a GP database, the study team have found that androgen excess increases the risk of fatty liver disease. The aim is to identify those women with PCOS who are at the highest risk of developing metabolic disease, which would allow for early detection and potentially prevention of type 2 diabetes, high blood pressure, fatty liver and cardiovascular disease. The investigator will assess clinical presentation, androgen production and metabolic function in women with PCOS to use similarities and differences in these parameters for the identification of subsets (=clusters) of women who are at the highest risk of metabolic disease. The investigator will do this by using a standardised set of questions to scope PCOS-related signs and symptoms and the patient's medical history and measure body composition and blood pressure. This standardised recording of a patient's clinical presentation (=clinical phenotype) is called Phenome analysis. The investigator will collect blood and urine samples for the systematic measurement of steroid hormones including a very detailed androgen profile (=steroid metabolome analysis) and of thousands of substances produced by human metabolism (=global metabolome analysis). Phenome and metabolome data will then undergo integrated computational analysis for the detection of clusters predictive of metabolic risk. Read Less

To evaluate the therapeutic efficacy and metabolic impact of a low energy diet (LED) in people with familial partial lipodystrophy and diabetes. Participants will be provided with a LED (total diet replacement) for 12 weeks, before the introduction of a stepped food transition. Metabolic effects will continue to be assessed for 1 year. In order to better understand why this intervention changes insulin sensitivity, we will also collect adipose and muscle tissue samples at baseline and 12 weeks into the intervention in participants willing to have these procedures performed. These samples will be used for histological, metabolite, gene expression and protein expression analyses. Read Less

DURANCE is a two part, phase Ib/II, multi-centre study to assess the safety and activity of S-488210/S-488211 in combination with durvalumab, in patients with non-muscle invasive bladder cancer (NMIBC). Read Less

HSCT has been implemented in (inter)national treatment guidelines for diffuse cutaneous systemic sclerosis (dcSSc) and is offered in clinical care and reimbursed by national health insurance in several European countries. However, data and specific guidelines on the best timing of HSCT in the course of dcSSc are lacking. In particular, it is unclear whether HSCT should be positioned as upfront therapy or as rescue treatment for patients not responding to conventional immunosuppressive therapy. This multicentre, randomized, open label trial aims to compare two treatment strategies used in usual care: upfront autologous HSCT versus usual care with (intravenous (i.v.) cyclophosphamide (CYC) pulse therapy followed by mycophenolate mofetil (MMF) and HSCT as rescue option).

This is a multicentre randomised 3-arm phase II clinical trial in patients with resectable Hepatocellular Carcinoma (HCC). Sixty patients will be randomized 1:1:1 to 6 weeks of pre-operative therapy with: pembrolizumab, lenvatinib or the combination of pembrolizumab and lenvatinib followed by up to 12 months treatment with post-operative pembrolizumab. The aim of the study is to compare the efficacy of pembrolizumab combined with lenvatinib with that of pembrolizumab and lenvatinib alone in terms of major pathological response in patients with resectable HCC. Major pathological response will be defined by the proportion of patients with less than 10% viable tumour at resection. Read Less

The goal of this clinical trial is to evaluate two treatment strategies in patients with chronic atrial fibrillation and heart failure, who are eligible for atrial fibrillation ablation. Patients will be randomized to either atrial fibrillation ablation or to implantation of a pacemaker with conduction system pacing followed by atrioventricular node ablation. The effect of treatment allocation on total mortality, cardiovascular hospitalization and heart failure hospitalization will be compared. Read Less

This clinical trial aims to explore the effect of Vitamin B6 supplementation on anxiety sensory hyperreactivity in autistic adults. Researchers will compare a placebo group to high-dose Vitamin-B6 to see if vitamin B6 reduce anxiety and sensory reactivity differences in autism. Read Less

This study aims to explore how smart devices can be used to monitor the health of individuals with eating disorders. Eating disorders are serious mental health conditions that impact both mental and physical health. Effective monitoring is crucial for developing treatment plans and ensuring the safety of individuals both in hospitals and at home. Currently, healthcare professionals use manual methods to measure important health indicators like heart rate, blood pressure, and BMI. These methods can be time-consuming and may not always accurately reflect a patient's health due to the possibility of patients concealing the severity of their condition. Furthermore, monitoring at home is challenging due to the lack of professional equipment and training for caregivers. With advancements in digital technology, smartphones and smartwatches now have the potential to collect and analyse health data in real-time. These devices can capture data on heart rate, blood pressure, respiratory rate, and other vital signs through non-invasive methods like analysing facial and fingertip blood volume, namely the photoplethysmography technology. Additionally, video recordings from smartphone cameras can be used to assess physical and mental health by analysing facial expressions, voice patterns, and physical movements. By utilising these digital tools, combined with validated questionnaires and tasks to assess participants' psychological status and the severity of disorders, this study expects to create a more efficient and accessible way for individuals with eating disorders to monitor their health at home. The study will collect data from participants both in hospital settings and during outpatient care to ensure the reliability and effectiveness of these digital methods across participants with different levels of severity. This comprehensive approach aims to improve early detection of health issues, optimise treatment plans, and ultimately enhance the quality of life for individuals with eating disorders. Read Less

Recently there has been concern about the effect of inhaled steroids, routinely used in the treatment of asthma, on the body's ability to produce its natural stress hormone cortisol. Failure of adequate cortisol production in times of stress e.g. illness, can result in serious illness or death. Patients receiving longterm steroid treatment may have reduced levels of cortisol and not be able to produce adequate amounts in times of need, a process called adrenal suppression. Initially it was thought that the absorption of inhaled steroids into the bloodstream would be too low to cause adrenal suppression however high profile deaths followed by a national survey revealed a number of fatal or near fatal cases of adrenal suppression. The vast majority of these were in children. Since then doctors have been encouraged to ensure that children on high doses of inhaled steroids carry a steroid alert card and that the ability of their adrenal glands to produce adequate amounts of cortisol is checked. However it is unknown what dose of inhaled steroids puts one at risk, whether age or gender affects one's risk and when to check the function of the adrenal gland. The Short Synacthen Test (SST) investigates the ability of the body's adrenal glands to produce cortisol. Presently the SST requires intravenous (i.v) cannulation through which Synacthen is injected to stimulate the adrenal glands and multiple blood samples are collected to assess the response in terms of cortisol production. It is invasive, time consuming and unpleasant for the child. Our project aims to produce a noninvasive alternative to the current SST, with Synacthen given nasally and using saliva to measure the subsequent production of cortisol. A noninvasive test will allow us to establish the first normal ranges for children and determine which children with asthma are at risk of adrenal suppression. Read Less

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.
