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.
Prospective observational study to qualify NM-MRI as progression marker in early Parkinson's.
ANCA-associated vasculitis is an autoimmune disease that causes damage to blood vessels. This leads to organ damage with the number of organs affected and the severity of damage varying significantly between patients. Vasculitis patients also have a very high risk of heart attacks and strokes, called cardiovascular disease. A chemical called 'endothelin', produced by the blood vessels, causes vessels to stiffen and raises blood pressure and this associates with cardiovascular risk. The investigators have previously shown that by blocking the effects of endothelin you reduce vessel stiffness, lower blood pressure and improve vessel function. However, these studies only blocked endothelin for a few hours. Now, the investigators would like to see if it is possible to maintain these benefits by blocking endothelin for longer. Sparsentan is a tablet that blocks endothelin and lowers blood pressure. The investigators plan to give sparsentan to patients with vasculitis for 6 weeks. To determine if any beneficial effects of sparsentan are due to blood pressure lowering the investigators will give another group of vasculitis patients a tablet called irbesartan which lowers blood pressure but does not block endothelin. The investigators will compare the results between the two groups.
Patients with lung disease who report breathlessness on exertion are often referred for a 6MWT. Due to the nature of the 6MWT (hereon referred to as a Max-6MWT), patients are required to walk as far as they can in 6 minutes. This may lead to an inaccurate assessment of their requirement for ambulatory oxygen as this form of exercise may not correspond to their normal daily activities. In this study, patients who are routinely referred for a Max-6MWT to investigate possible exercise-induced hypoxaemia will be invited to perform an additional walking test which is performed at their normal walking speed, referred here on in as a Nor_6MWT. We hypothesise that performing a Nor_6MWT will provide a more accurate assessment of a patients' oxygen requirement, primarily from their oxygen desaturation during the test.
ARISTOCRAT is a phase II, multi-centre, double-blind, placebo-controlled, randomised trial to compare the cannabinoid Nabiximols with placebo in patients with recurrent MGMT methylated glioblastoma (GBM) treated with temozolomide (TMZ).
This is a Phase III, randomized, open-label, 3-arm, multicenter, international study assessing the efficacy and safety of Dato-DXd with or without durvalumab compared with ICT in participants with stage I to III TNBC with residual invasive disease in the breast and/or axillary lymph nodes at surgical resection following neoadjuvant systemic therapy.
Cataracts are the major cause of blindness in the world. Cataract surgery, being the most performed surgery in the world today, provide correction by extracting the natural lens from its capsular bag and replaced by an artificial intraocular lens (IOL) implantation. In the UK, almost all patients undergoing cataract surgery by the NHS are given monofocal intraocular lenses (IOLs) which do not correct corneal astigmatic error. It is estimated that around 20% of the population has over 1.50DC of corneal astigmatism. Uncorrected astigmatism not only increase spectacle dependency and reduce quality of life post surgically, but it also adversely affects the overall economic costs. Specialised toric IOLs offer the opportunity to correct pre-existing corneal astigmatism. Previous work has shown a link between reduced vision and balance or mobility. Full correction of refractive error may have greater impact on lifestyle than previously thought.
The goal of this observational patient registry is to learn how expert centers treat patients with chronic thromboembolic pulmonary hypertension (CTEPH). CTEPH is a condition in which blood clots block the blood vessels in the lungs. There are currently three treatment options for patients with CTEPH: - surgery to remove blood clots from large vessels in the lungs (pulmonary endarterectomy (PEA)) - the use of a small balloon to unblock smaller blood vessels (balloon pulmonary angioplasty (BPA)) - drugs Patients can also receive a combination of these treatments. The main question this registry aims to answer are: - How many patients receive a given kind of treatment? - How do expert centers combine the different treatments? - Are patients doing better after they receive a given kind of treatment? - How many patients are alive 1, 3 and 5 years after they receive a given kind of treatment? Participants will receive the same treatments that they would receive if they did not participate in the study. During the study, patients will visit their doctors as they would do normally. The doctors will collect information on the patients' health and enter it into the study database. The follow-up time will be at least 3 years for all patients.
Indonesia is one of the countries that does not sign The World Health Organization Framework Convention on Tobacco Control (WHO-FCTC), and the numbers of Indonesian smokers increase every year. The Volitional-Help Sheet (VHS) has been used successfully to help people quit smoking, but has not yet been tested in Indonesia. The present study aims to adapt and implement the VHS to promote smoking cessation among smokers aged 20- 45 years. The main outcome measure is smoking abstinence; secondary outcomes are nicotine dependence, and capabilities, opportunities and motivations.
Background There are no prospective trials comparing the two main reconstructive options after colectomy for Ulcerative colitis, ileal pouch anal anastomosis and ileorectal anastomosis. An attempt on a randomized controlled trial has been made but after receiving standardized information patients insisted on choosing operation themselves. Methods Adult Ulcerative colitis patients subjected to colectomy eligible for both ileal pouch anastomosis and ileorectal anastomosis are asked to participate and after receiving standardized information the get to choose reconstructive method. Patients not declining reconstruction or not considered eligible for both methods will be followed as controls. The CRUISE study is a prospective, non-randomized, multi-center, controlled trial on satisfaction, QoL, function, and complications between ileal pouch anal anastomosis and ileorectal anastomosis. Discussion Reconstruction after colectomy is a morbidity-associated as well as a resource-intensive activity with the sole purpose of enhancing function, Quality of Life and patient satisfaction. The aim of this study is to provide the best possible information on the risks and benefits of each reconstructive treatment.
TRACERx EVO is a programme of work using a prospective observational cohort study of participants with early- and late-stage non-small cell lung cancer (NSCLC), small cell lung cancer (SCLC) and pleural mesothelioma.
