There are about 25435 clinical studies being (or have been) conducted in United Kingdom. The country of the clinical trial is determined by the location of where the clinical research is being studied. Most studies are often held in multiple locations & countries.
This research aims to improve the way of deciding whether a lump in soft tissue such as fat or muscle is a type of cancer called a soft tissue sarcoma, or if it is benign (non-cancerous). To do this the investigators will use routine clinical MRI scans, additional quantitative MRI scans and artificial intelligence. The aims of this research are: To develop AI algorithms that can accurately classify soft tissue masses as benign or malignant using routine and quantitative MR images. To classify malignant soft tissue masses into their pathological grade. Compare different AI models on external, unseen testing sets to determine which offers the best performance. Participants will be asked if they can spend up to a maximum of 10 extra minutes in an MRI scanner so that the extra images can be acquired. A small subset of participants will be invited back so the investigators can check the reproducibility of the images and the AI software.
This is a Phase 2, international, multicenter, randomized, double-blind, placebo-controlled, dose-ranging, 12-week study. It is designed to assess the therapeutic dose, efficacy, and safety of treatment with SAR441566 in male and female adults with moderate to severe plaque psoriasis. Study details include a screening period (4 weeks and not less than 11 days before Day 1), a treatment period (12 weeks ± 3 days) and a post-treatment period (safety follow-up) (2 weeks ± 3 days). The total number of study visits will be 7.
This study will investigate the role of a portable Continues Positive Airway Pressure device (pCPAP) in management of patients with symptomatic Excessive Central Airway Collapse (ECAC). ECAC is characterised by complete or partial collapse of central airways on exhalation. In some cases, this can cause persistent breathlessness and severely limited exercise capacity. Current treatment options for ECAC are very limited. Standard assistive breathing devices such as CPAP machines are sometimes used to relieve symptoms at night or at rest. This does not address breathlessness during activity which drives accumulation of disability over time. The main aims of this project are to assess the effect of a portable CPAP (pCPAP) device on exercise capacity and symptoms and evaluate the feasibility of wearing pCPAP at home during routine activities. Lightweight battery-powered portable CPAP devices have been recently developed to facilitate travel to remote areas by people with Obstructive Sleep Apnoea (OSA). Patients with ECAC can wear them during physical activity to prevent airway collapse but their potential benefits have not been evaluated in clinical trials. For this study, the investigators will recruit 20 patients with ECAC who will attend for two study visits 4-6 weeks apart in a single centre (The Royal Papworth Hospital). The primary outcome measure will be a shuttle walk test performed repeatedly with and without pCPAP in a randomised order. Secondary outcomes will include assessment of activity level, breathlessness, quality of life ,pCPAP usage and its acceptability. The study will evaluate a pragmatic way of CPAP titration and application. Previously acquired diagnostic baseline computed tomography (CT) scans will be analysed with a novel Functional Respiratory Imaging (FRI) tool. This software tool will enable retrospective reflections on the changes occurring within the lungs for patients with ECAC. This may help identify predictive features of potential pCPAP responders and inform future use.
This study will assess the safety and efficacy of avutometinib (VS-6766) in combination with defactinib versus Investigator's choice of treatments (ICT) in subjects with recurrent LGSOC who have progressed on a prior platinum-based therapy.
Food nutritional labels are one way to support people to make more informed, healthier food choices. However, there is limited evidence from trials showing that nutrition information on food or drinks is changing the food purchasing or food/beverage consumption behaviours. Many people do not understand the meaning of kilocalories (kcals, calories) or grams of fat displayed on food labels, and often underestimate the number of calories when labelling is not provided. An alternative or complementary approach to current nutrition labelling, is to provide calorie information with a clear interpretation of what the calorie content of the food item/meal or beverage means in terms of energy expenditure. This approach has been called physical activity calorie equivalent (or expenditure) labelling (PACE), which aims to show the public how many minutes (or miles/kilometres) of physical activity (e.g. walking or running) are equivalent to the calories contained in food/beverages. For example, "the calories in this chocolate bar require 95 minutes of walking to burn off". One context in which the public consume a lot of calories is from vending machines. We hypothesise that providing consumers with PACE information on hot beverage vending machines will reduce the average number of calories per transaction dispensed from the vending machines compared with when no PACE information/labelling is presented on vending machines. The study will adopt what is called a stepped wedge randomised controlled trial design involving 42 hot beverage vending machines in 27 buildings (clusters). Clusters will be randomly allocated to one of eight sequences across 24 weeks, which will dictate the time (weeks) at which clusters display the vending machine PACE labelling intervention. Weeks one to four will constitute a baseline period, during which the data will be collected from all vending machines without PACE labelling in place. This will be followed by 20 weeks during which the PACE labelling intervention will be introduced and maintained at each building according to a stepped wedge design (Figure 2). Specifically, every two weeks, three or four clusters will move to the intervention condition. The number of transactions from the vending machines will be collected over the study period and we will compare the number of transactions in the weeks when the PACE labelling is displayed compared to when it was not.
Psychological distress (anxiety and depression) is common in and experienced differently by people living with long-term health conditions (LTCs). Being able to measure whether psychological distress is related to living with a LTC would allow researchers and clinicians to provide interventions specifically tailored to the challenges of living with a LTC and therefore provide the most appropriate support for these patients. Such a measure would also be useful in research to identify the presence of illness-related distress in different patient groups. This project will therefore create a new measure of illness-related distress that has applications for both research and clinical practice. This will involve the psychometric validation of the new illness-related distress measure to test how valid and reliable the measure is. The aim of the project is to provide initial validation of the Illness Related Distress Scale in a community sample, recruited through online platforms. The objective of the study is to gather initial validity and reliability data for the scale.
This study will assess the feasibility of performing pre-hospital resuscitative endovascular balloon occlusion of the aorta (REBOA) as an adjunct to conventional Advanced Life Support (ALS) in patients suffering from non-traumatic out of hospital cardiac arrest (OHCA). As well as providing valuable insights into the technical feasibility of performing this procedure as part of a resuscitation attempt, the study will also document the beneficial physiological effects of REBOA in this group of patients.
Prehabilitation is the use of exercise prior to surgery to improve peoples' fitness, which leads to improved outcomes of surgery. This service is now being run remotely, however, there is little existing evidence to support the best practice for this. Currently, baseline fitness is assessed remotely using either a sit to stand test or a step test. Once completed people are prescribed regular exercises and asked to exercise to a level of intensity using a measure called Rating of Perceived Exertion (RPE). However, these measurements may not be reliable. We are carrying out a study to assess if another waking test (modified Rockport test) and asking patients to exercise to a target heart rate are better measures of assessing baseline fitness and exercise intensity. All participants will receive weekly telephone calls to check their progress and be provided with a wrist worn fitness tracker (Fitbit). Participants will be randomised to one of two groups. The only difference between the groups will be the way the exercise is prescribed. In one group participants will be asked to complete the exercises to an exercise level they find "somewhat hard". The other group will be asked to complete the exercises to maintain a set heart rate. All participants will be asked to complete an activity log (submitted weekly) as an online form. A small group of people (maximum 10) will be asked if they would like to complete an in-person baseline fitness assessment also, this is optional. This study runs for up to eight weeks with participation ending after eight weeks or at the time of surgery, whichever is sooner. In the final week of participation, participants will be asked to complete an online questionnaire about their experience of using a wearable fitness tracker during the prehabilitation programme.
- 40% of patients presenting with stable chest pain (angina) have no significant blockage of the main heart arteries. Identifying why these patients have symptoms will mean better treatment options can be developed. - About 60% of these patients have evidence of coronary microvascular disease (CMD). In this condition there is a problem with the heart's microvessels (very small blood vessels that branch from the main heart arteries). Due to problems with these vessels there is a mismatch between the blood supply to the heart and its oxygen consumption, causing chest pain and this can also lead to major heart events. - At present, to diagnose this condition, specialised techniques during an invasive test, called a coronary angiogram, are required. As this is an invasive test, it can be lead to complications and cause discomfort. - Non-invasive ways of diagnosing CMD are required to improve the diagnosis and management of this condition. - This study aims to provide initial data on whether novel imaging techniques using CT and MRI scans, which are much less invasive, could identify CMD. - To do this, patients with suspected angina referred for angiography and who are already participants in the main research study 'CMR versus CT-FFR in CAD' study will be recruited. - These will be patients with suspected CMD and also those with blockage of the main heart arteries (triple vessel disease) to compare against. - Participants in this pilot study will have additional tests used to diagnose CMD during their invasive angiography procedure. Participants will then have an MRI scan involving novel techniques and exercise MRI, where individuals exercise use a cycle or stepping machine during the MRI scan. Further analysis will also be undertaken of CT images acquired as part of the main study. - These tests will be compared against invasive test results to see which show potential in being able to diagnose CMD.
The purpose of this research study is to find out the safety and effectiveness of a new medical device called H-Guard. During this research study, participants will receive the standard of care haemodialysis treatment, as decided by the treating doctor. Participants will be observed during 5-6 haemodialysis treatments throughout the course of the study. The only change to the treatment process, will be the use of the medical device (H-Guard) to prime the dialysis system, before one of the treatments. Participants will have various blood tests taken throughout the course of the study for safety and research analysis.
