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.
The aim of this study is to assess the clinical utility of the whole blood transglutaminase-based rapid test against current serological tests and the gold standard of duodenal biopsy. The investigators will recruit patients (n=1000) from the endoscopy department at the Royal Hallamshire Hospital, Sheffield, United Kingdom (UK). The patients recruited for this study will already have been referred for a consultation and gastroscopy. In addition, these patients will already have been serologically tested for IgA TTG, EMA and a total IgA immunoglobulin level (as per normal clinical practice). All duodenal biopsy specimens will be fixed in buffered formalin and embedded in paraffin wax. Standard, 3μm thick sections at three levels will be stained with haematoxylin and eosin and reported routinely. Additionally, biopsies demonstrating increased intraepithelial lymphocytes only (changes compatible with but not diagnostic of coeliac disease) will be stained with KiRAS or CD4/CD8 which are markers for coeliac disease.
This study will assess whether Toll like receptor 7 (TLR7)-mediated pharmacology, with intranasal (i.n.) GSK2245035 20 nanogram (ng) administered weekly for a period of 8 weeks, will lead to reduced allergic reactivity in the lower airways in subjects with mild allergic asthma. This will be a randomised, double-blind (sponsor open), placebo-controlled, parallel group, 8-week treatment study. The study will consist of a screening period of up to approximately 4 weeks (involving two screening visits), a blinded treatment period of 8 weeks, followed by a follow-up period of up to 3 months. The total duration of the study for each subject will therefore be a maximum of approximately 6 months.
This is a study to evaluate the safety and pharmacokinetics in pediatric patients with secondary hyperparathyroidism receiving a single dose of etelcalcetide at the end of hemodialysis.
The study is divided into 2 parts. The first part of the study will be double-blinded and will last for 24 weeks. During this time, participants will be randomized in a ratio of 2:1 to receive either evolocumab once monthly (QM) or placebo QM. The second part of the study is a 24-week open label extension period. During this time all participants will receive evolocumab QM. The clinical hypothesis is that subcutaneous evolocumab QM will be well tolerated and will result in greater reduction of low density lipoprotein cholesterol (LDL-C), defined as percent change from baseline at Week 24, compared with placebo QM in human immunodeficiency virus (HIV)-positive participants with hyperlipidemia or mixed dyslipidemia.
Endoscopic submucosal dissection (ESD) is an endoscopic resection technique used to treat superficial neoplasia in the gastrointestinal tract. Bleeding is a commonly encountered problem during submucosal dissection and is usually managed with electrocautery. However, this does carry a risk of deep thermal injury and perforation. PuraStat® is a novel extracellular scaffold matrix of amino acids that forms a transparent adherent barrier when applied to a bleeding point. The aim of this trial is to study the use of PuraStat® in reducing the need for thermal haemostasis during ESD.
This trial will evaluate the safety, tolerability, pharmacokinetics, and pharmacodynamics of repeat dosing of UTTR1147A in participants with neuropathic diabetic foot ulcers that do not respond adequately to standard wound care. Participants across multiple sites will be assigned to one of five cohorts (Cohort A, B, C, D, and E) based on the eligibility criteria and randomized to receive subcutaneous (SC) injections of either UTTR1147A or placebo over 12 weeks in addition to standard wound care.
This research aims to determine whether selenium supplements improve bone and muscle health in older women at risk of osteoporosis (low bone density or weak bones) and fracture (broken bones). Osteoporosis is a major public health problem. One in two women and one in five men over age 50 will have a fracture. Fractures cause pain, disability and reduce life-expectancy. Women with below-average bone density around the time of the menopause might have previously taken hormone replacement (HRT) to prevent osteoporosis, but HRT is much less used now due to side effects. Therefore there is a need for safe, effective and inexpensive preventative interventions for women at risk of osteoporosis. Selenium is a chemical nutrient present in several human proteins, including anti-oxidants. Anti-oxidants may protect against ageing of tissues, including bone, by mopping up damaging reactive oxygen molecules (sometimes called 'free radicals'). Selenium is present in soil, and so is obtained from many foods. However, soil selenium levels are low in Europe, and dietary intake in the UK is below recommended levels. We previously found that women with higher blood selenium levels have stronger bones, but this doesn't prove that giving selenium will improve bone strength. The investigators propose a randomised controlled trial to compare selenium supplements with a placebo (dummy treatment) in women with below-average bone density. The investigators will give selenium (at two different doses) or placebo to 120 women for six months and use blood and urine tests and bone density scans to see if giving selenium does have any effect on bone. The investigators will also do muscle function tests and measurements of free radical molecules.
Although the first outpatient review following cardiac surgery is conventionally scheduled for six weeks after hospital discharge, there is no evidence to support this practice. Thirty-day mortality and morbidity rates, which are now widely used as indicators of the quality of surgical care, reveal rates that are higher than corresponding in-hospital rates. Secondly, the rates for mortality and morbidity occurring up to 6 weeks after surgery are not known. The objectives of our study are to determine the postoperative mortality and morbidity rates in the 6-week interval between hospital discharge and the first planned specialist review after cardiac surgery, and to assess the level of patient satisfaction with current practice. The study will enrol eligible patients who are undergoing elective and urgent coronary artery bypass and/or valve surgery at our institution over a 6-month period and provide them with study information. Prior to discharge after surgery, prospective participants will be consented and given a questionnaire to take home, complete and bring along to the outpatient appointment. The investigators will analyse the data to determine the rates and timing of the complications, and the impact on postoperative recovery. The investigators will also assess the level of patient satisfaction with the current practice. Appropriate conclusions either in support of current practice or, a change in practice would be drawn..
The objective of this pilot study is to explore whether repeat doses of AUT00063 can provide an indication of improvement in performance of tests across a battery of speech and hearing assessments in cochlear implant users.
The objective of the study is to investigate the efficacy, safety and pharmacokinetics of four different doses of BI 425809 once daily compared to placebo given for 12 weeks in patients with schizophrenia on stable antipsychotic treatment.
