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.
Angina and heart attacks are caused by narrowings in the coronary arteries (blood vessels) supplying the heart. These narrowings can be opened using a balloon and stent (angioplasty). Traditionally, stents are constructed from metal and are permanent. However, newer stents are being constructed from carbohydrate polymers (scaffolds), which allow them to reabsorb over time leaving no permanent implant. New data has suggested that these scaffolds appear to reduce recurrent angina and may alter the blood flow down the artery. However, it is not known whether this is due to the scaffolds themselves or the way the scaffolds are inserted. In this study we hope to measure the blood flow to the heart and assess changes in that flow during stent and scaffold insertion. It is also important to know whether these effects are durable and thus, a cohort of patients will return at 3-months to be restudied. These data are important to help us understand why blood flow is affected by stent/scaffold selection or device implantation technique and whether this results in better long-term outcomes.
Glioblastoma (GB) is the commonest form of brain cancer in adults. Despite current treatment options including surgery, radiotherapy and chemotherapy, overall survival is poor. Therefore, other treatment options are being explored and there is increasing interest in the possibility of using the ketogenic diet (KD), alongside current treatment options. The KD is a high fat, low carbohydrate diet. This encourages the body to use fat (broken down to ketones) as its primary energy source, instead of carbohydrate (broken down to glucose, a type of sugar). KDs have been considered for use in patients with GB as this type of cancer is thought to use glucose as its main energy supply, which is of short supply in this diet. Animal studies have shown KDs may make GB more responsive to radiotherapy and chemotherapy and could improve survival by slowing the cancer's growth. However, clinical studies are needed in humans to assess any possible benefits. This trial will see patients randomly assigned to one of two types of KDs; the modified ketogenic diet (MKD) and the medium chain triglyceride ketogenic diet (MCT). Both diets follow the same high fat, low carbohydrate principles, with the MCT diet requiring the patient to take some of the fat as a supplement drink instead of as food. Patients will follow the diet for 12 weeks initially. The trial will look to enroll newly diagnosed GB patients, from The Walton Centre NHS Foundation Trust over a 12 month period. The aim of the trial is to investigate protocol feasibility and patient impact by comparing two KDs in an NHS setting, with a view to informing future phase III clinical trials.
GSK3036656 is being developed by GSK for the treatment of tuberculosis (TB). This is the FTIH study for GSK3036656 to evaluate the safety, tolerability and PK of single ascending and repeat oral doses of GSK3036656 in healthy adult subjects. The results of this study are intended to be used to identify appropriate and well-tolerated doses of GSK3036656 to be used in further studies. A food effect assessment will also be undertaken to investigate the influence of food on the PK of GSK3036656. The study will be conducted in two parts: Part A (single dose) and Part B (repeat dose). Up to two cohorts will be included in Part A. 9 healthy adult subjects will be included in each cohort. Each cohort will participate in up to 4 treatment (dosing) periods including a food effect treatment period. During each treatment period, GSK3036656 will be administered to 6 subjects and placebo will be administered to 3 subjects. The starting dose in Part A will be 5 milligrams (mg), and the maximum dose will be 1500 mg. The two cohorts in Part A will be dosed sequentially (i.e., dosing in Cohort 2 starts after dosing in Cohort 1 is completed). Initially, there will be a 14 day wash out period for individual subjects between each dose level. Study progression to Part B from Part A will be based on an acceptable safety, tolerability and PK profile in Part A. Part B will comprise up to 4 cohorts (Cohorts 3, 4, 5, and 6) each containing 10 (8 active: 2 placebo) healthy adult subjects to examine the safety, tolerability and PK of a repeated daily dose of GSK3036656 over a period of up to 14 days. Appropriate doses and dose regimens for Part B will be selected based on available safety, tolerability and PK data from Part A and/or any preceding repeat dose cohorts from Part B. Dividing the total daily dose into 2 or 3 smaller doses may be done in both Part A and Part B. Up to 18 subjects will be enrolled into Part A and up to 40 subjects will be enrolled into Part B. The total duration of the study for each subject recruited into Part A and Part B will be approximately 12 weeks and 8 weeks, respectively.
To learn in a general Cardiac Resynchronization Therapy Defibrillators (CRT-D) population, which optimization techniques are used and how effective they are. It will compare 12-month response rates among different optimization methods and characterize which selected subject subgroups achieve better response than others. A subset of SMART Registry subjects will contribute to the NG4 Post Market Clinical Follow Up (PMCF) Cohort whose objective is collecting data on the NG4 CRT-D features and device usage in a real world setting and monitor long term safety associated with these devices to support CE Mark.
Barrett's oesophagus is a condition where the lining of the oesophagus (gullet) wall changes. People with Barrett's oesophagus are at risk of developing oesophageal cancer but can have regular checkups to detect changes before they progress to cancer. Every two years patients with Barrett's are offered examination by passing a fibreoptic tube into the oesophagus (gastroscopy) to remove small tissue samples (biopsies), which are examined in the laboratory to check for changes. Bowel cancer is the third most common cancer in the UK, and the second leading cause of cancer deaths. Prevention and early detection are the most effective strategies of dealing with bowel cancer. Most cancers develop from benign polyps (growths) in the bowel. Polyps are common and have the potential of developing into cancer over the course of many years. Patients with a prior diagnosis of Barrett's oesophagus and colonic polyps undergo regular endoscopic examinations known as surveillance endoscopies. This is done to detect changes in the cells of Barrett's oesophagus or further polyps. Current practice is to capture recorded videos of Barrett's surveillance examinations and still images of polyps prior to their removal. Endoscope technology continues to advance. These newly developed technologies are marketed to have claims of superiority in performance over preceding generations often without the back up of scientific data but at a significant financial cost. The aim of this study is to use endoscopic images and videos recorded as part of routine clinical practice to compare the current version of Olympus endoscopes with the new version launched by the company.
This study aims to increase the well-being of individuals with chronic pain through a 4-week online positive mindfulness programme. Each module, lasting 4 days, will include a daily meditation and focus on a different aspect of positive psychology. This is a quantitative study. The independent variable is participation in the programme. The dependent variables are: wellbeing, mindfulness, pain severity, pain catastrophising and health quality of life. There will be one experimental group who participate in the programme as soon as they are recruited. There will be one control group who are put on a 'wait-list' to complete the programme after an 8 week wait. Pre and post measures will be taken. Participants are being recruited through NHS clinics in London and Oxford, including the Pain Management Centre at Oxford University Hospitals (Churchill site) and INPUT at St Thomas's Hospital (which are participant identification centres). Participants who hear about the study via other means including online or through word of mouth are also being accepted.
Total hip replacement is one of the most successful surgical procedures of modern times, with over 80,000 performed each year in the UK. However, up to 5% of all primary hip replacements need to be revised within the first 10 years, and in many cases malposition of the acetabular (hip socket) component is implicated in the early failure. The standard method of positioning the acetabular component is for the surgeon to be guided by a combination of the visible anatomical landmarks within the surgical field, and the wider environment of the operating theatre. The advent of 3D printing has led to the development of custom-made surgical guides which can be used during surgery, in order to assist the surgeon in the positioning of instruments and devices. These surgical guides are manufactured based on CT or MRI imaging, and are designed to clearly indicate to the surgeon the desired location and orientation of bony cuts and implant positions. This study will test the hypothesis that an acetabular alignment guide combined with three-dimensional CT-based planning using the Corin OPS™ (Optimised Positioning System), provides more accurate component alignment following primary total hip replacement compared with the current standard treatment, with the aim of improving patient outcomes and reducing the risk of complications of total hip replacement.
This study aims to assess the effect, if any, on the adenoma detection rate of BowelScope bowel cancer screening flexible sigmoidoscopies by using the Endocuff Vision device.
The purpose of this post-market study is to evaluate UFE agents for the treatment of symptomatic uterine fibroids, using Gel-Bead compared to four other commonly used embolic agents.
The investigators wish to assess whether intensive periodontal therapy will reduce the burden of chronic periodontal disease and will cause regression or prevent progression of atherosclerosis assessed by a surrogate end-point (carotid intima-media thickness) at 24 months compared to control periodontal therapy.
