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 is a randomised, placebo-controlled, double-blind, crossover, phase IIa study to investigate the efficacy and safety of oral LAT8881 in neuropathic pain.
This is a cross-over randomized study. Eligible participants are preterm infants born at less than 37 weeks gestation (23+0 to 36+6 weeks), who are receiving conventional mechanical ventilation through an endotracheal tube and have a need for supplemental oxygen at the time of enrolment. The planned sample size is 19 subjects completing the study with both arms (38 study periods). The objective of this crossover study is to evaluate the efficacy of the automatic oxygen control function with or without Volume Guarantee®(automatic control of ventilator pressure to deliver the set volume) mode of ventilation in keeping oxygen levels in the safe target range (90 to 95%) in ventilated preterm infants requiring oxygen therapy.
People of black African and Caribbean descent have a greater risk of developing type 2 diabetes than white Europeans. The aim of this study is to increase our knowledge of how the condition may arise, and what underlies this increased risk. Following a successful screening visit to confirm eligibility for the study, we will be investigating how quickly a glucose drink empties out of the stomach in 30 white Europeans and 30 people of black African or Caribbean descent. In addition, we will study the impact that gastric emptying rate has on blood glucose and satiety hormones released normally by the gut in response to eating. Blood and breath samples will be collected before and during an oral glucose tolerance test.
This study will investigate whether administration of a single dose of the serotonin receptor subtype 4 (5-HT4) partial agonist prucalopride has effects on emotional processing and non-emotional cognition in healthy volunteers, compared to placebo administration. Using an experimental medicine approach, the effects of prucalopride on cognitive biomarkers of antidepressant action will be characterised. In a double-blind design, participants will be randomised to receive a single dose of either prucalopride (1mg) or placebo. All participants will come for a Screening Visit to ensure their suitability for the study. If they meet study criteria, they will be invited to a Research Visit, where they will receive the study medication and wait for two hours while the drug reaches peak levels. After two hours they will be asked to complete a series of computer-based tasks measuring emotional, non-emotional cognitive processing, and reward processing. The primary study hypothesis is that acute prucalopride administration will have positive effects on processing facial expressions of emotion. Secondary hypotheses are that acute prucalopride administration will affect other measures of emotional processing, and non-emotional cognition.
The purpose of this study is to evaluate the efficacy, safety and pharmacokinetics of patisiran in participants with hereditary transthyretin-mediated amyloidosis (hATTR amyloidosis) with disease progression after liver transplant.
This trial aims to reduce unnecessary prescription of antibiotics and broad spectrum antibiotics by general practitioners (GPs) in England. Unnecessary prescriptions are defined as those that do not improve patient health outcomes. The intervention is to send GPs a letter from the Chief Medical Officer (CMO) that gives feedback on their practice's prescribing levels. Specifically the sample was GPs whose practices whose prescribed more than 1.161 items per STAR-PU or whose practices prescribed more that .965 items per STAR-PU and greater than 10% broad spectrum items. The intervention groups received a letter telling them they are among the highest prescribers of either their total or broad spectrum antibiotics, with a graph showing their prescribing compared to average prescribing ("their peers"). The letter also contained a leaflet to help GPs discuss self-care advice with patients and some advice to use delayed prescriptions. The investigators hypothesize that the antibiotic prescribing rate in will be lower for the treatment group compared to the control group, following the receipt of the letter.
Covered stents (CS) are a potentially lifesaving treatment for grade III coronary perforation but delivery can be challenging, and the long-term durability and safety including risk of acute stent thrombosis are unknown. The GNOCCI study aims to evaluate long term outcomes after coronary perforation including patients treated with covered stents.
Prospective, Non-randomized, Single-arm Study to assess the accuracy of intracardiac echocardiography (ICE) for characterization of arrhythmogenic substrate in patients with ischaemic cardiomyopathy undergoing ventricular tachycardia (VT) ablation
The purpose of the study is to evaluate clinical efficacy of rozanolixizumab as a treatment for subjects with chronic inflammatory demyelinating polyradiculoneuropathy (CIDP).
This study is to understand the changes occurring in a blood clotting protein, von Willebrand factor (VWF), in patients undergoing cardiac surgery who receive the blood thinner called Heparin. These patients are given Heparin through their veins, to prevent blood clot formation as it passes through the heart bypass machine. At the end of the operation, the effect of Heparin is reversed by another drug, Protamine Sulphate. Heparin prevents blood clots forming mainly by inactivating thrombin, a crucial protein needed for blood clotting. This effect of Heparin is monitored through blood tests called the 'Anti Factor-Xa' and the 'APTT'. Heparin has another effect on clotting: it can block the attachment of special blood cell fragments called platelets to damaged blood vessels, but this effect is not usually measured. Following blood vessel injury, the large VWF sticks to the damaged surface and captures platelets to form a 'plug' which stops bleeding. The platelet plug is then stabilised by other clotting proteins. This stops blood loss and allows vessel repair underneath. Heparin blocks the ability of VWF to capture platelets at the site of blood vessel injury. The higher the dose of Heparin, the greater this blocking effect is. This secondary effect of Heparin cannot be readily monitored and may explain why bleeding complications occur in patients receiving Heparin despite the monitoring with blood tests used. This study will look at the blood levels of Heparin, VWF and platelets before, during and after surgery and how well VWF functions in the presence of heparin, including its ability to attach to platelets. The investigators will determine if all of the heparin related changes in blood clotting can be detected using a method that looks at all of the different steps in forming a blood clot.
