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 the study is to demonstrate the non-inferiority in terms of acute bronchodilator effect between a single dose of CHF 1535 NEXThaler 200/6 µg and a single dose of CHF 1535 NEXThaler 100/6 µg at two dose levels in partially controlled and uncontrolled asthmatic patients.
Normal ageing affects vision as a result of preretinal and retinal changes. Photoreceptors, the light sensitive cells in the retina, degenerate and the rods (responsible for night vision) are most susceptible to damage with increasing age. Rod loss leads to poor vision in the dark which increases the risk of accidents amongst the elderly. Macular pigment (located in the photoreceptors)is thought to protect the retina and reduce the risk of age related changes. Dark adaptation, mediated by the rods, slows down with age, and is also reduced in AMD (age-related macular degeneration). Recent evidence suggests that lutein (the main component of macular pigment) supplementation improves the dark adaptation deficit in AMD subjects. Research into the effects of lutein in a normal human has not been previously conducted. Since the older population is increasing, our aim is to firstly establish the extent of night vision loss (using dark adaptometry) and secondly to examine the possibility of slowing down or reversing this loss through lutein supplementation.
The investigators will study Radial artery injury and endothelial function following trans-radial cardiac catheterisation. Radial artery injury will be quantified pre- and post- angiography using Optical Coherence Tomography. The participants will also have radial endothelial function assessed using flow-mediated dilatation at baseline, 24 hours, one week, one month and three months post- angiography. Blood will be taken pre and 24 hours post angiography for characterisation of endothelial progenitor cell numbers and function. The hypothesis is that trans-radial catheterisation will cause a reduction in flow-mediated dilatation which peaks at 24 hours and recovers at three months. The investigators hope to correlate the rate of this recovery with peri-procedural progenitor cell numbers.
A comparative evaluation of a newly marketed multifocal contact lens with a single vision contact lens when used with near vision spectacles. The evaluation was to quantify the difference between the two test corrections.
The purpose of this study is to evaluate whether sparing the hippocampi during whole brain radiotherapy following neurosurgery or stereotactic radiosurgery in patients with brain metastases from a systemic tumour helps preserve brain function.
Three groups of 8 Japanese males are given single ascending doses of ASP1707 or placebo to assess the safety and tolerability, and to evaluate how it is absorbed, metabolized and distributed through the body.
Schizophrenia is a chronic psychiatric illness with periods of remission and relapse. Patients vary in the frequency and severity of relapse, time until relapse and time in remission. Discontinuation of antipsychotic medication is by far the most important reason for relapse. A possible method to optimize medication adherence is to treat patients with long-term, depot medication rather than oral medication. However, despite its apparent "common sense" this approach has neither been universally accepted by practicing psychiatrists nor unequivocally demonstrated in clinical trials. Therefore, in this study we aim to investigate possible advantages of depot medication over oral antipsychotics in an independently designed and conducted, randomized, pragmatic trial.
Oral iron supplementation is often associated with rapid onset of gastrointestinal side-effects. The aim of this study was to develop and trial a short, simple questionnaire to capture these early side-effects and to determine which symptoms are more discriminating. The study was a double-blind placebo-controlled randomized parallel trial with one week treatment followed by one week wash-out. Subjects were randomized into two treatment groups (n=10/group) to receive either ferrous sulphate (200 mg capsules containing 65 mg of iron) or placebo, both to be taken at mealtimes twice daily during the treatment period. Subjects completed the questionnaires daily for 14 days. The questionnaire included gastrointestinal symptoms commonly reported to be associated with the oral intake of ferrous iron salts (i.e. nausea, vomiting, heartburn, abdominal pain, diarrhoea, and constipation).
Due to an unexpectedly high number of infant deaths from whooping cough in 2012, the Department of Health acted to protect newborns between birth and completion of primary immunisations, the period with greatest risk of disease. Vaccination of pregnant women with whooping cough vaccine in the third trimester of pregnancy was instigated nationally, so that antibodies produced by the Mum would cross the placenta to the unborn child, giving them passive protection at the most vulnerable time. This antibody transfer has been known for some time but has not been compared between the two whooping cough vaccines being used in pregnancy. Any effect the raised antibody might have on infant responses to the vaccines given in the first few months of life has also not been measured. This is particularly important as the infant immunisations include some of the same components as the whooping cough vaccines, which include diphtheria, tetanus and polio. Previous studies have shown that high levels of antibody prior to vaccination may affect subsequent antibody responses. It is therefore important to assess whether administration of the whooping cough vaccine in pregnancy adversely affects the protection afforded by the infant vaccines, particularly to those which are similar, namely tetanus and diphtheria as well as meningitis C and Hib vaccines which include diptheria and tetanus components in their structures. This study will assess immune responses of mothers and their babies (~200 pairs) to their vaccinations and will allow the comparison of two whooping cough vaccines being used in pregnancy. This will be done by taking small amounts of blood, which is the only way to measure antibody levels (the proxy of the immune response), before and after the vaccinations. A group of unvaccinated women and their babies (50 pairs) will also be recruited to allow comparison of their immune responses.
Losmapimod is a new anti-inflammatory medication which potentially may benefit patients with Acute Coronary Syndrome, (ACS), a condition which includes heart attack. There is a growing understanding that the inflammatory response to ACS is integral to the subsequent evolution of plaque instability. Losmapimod inhibits p38 mitogen activated protein kinase (MAPK), an enzyme which may play a central role in inflammation in the setting of heart attack. Inhibition of p38 MAPK may stabilize atherosclerotic plaques, reduce the risk of subsequent plaque rupture, indirectly improve vascular function and prevent subsequent thrombosis, and thus reduce infarct size and the risk of subsequent cardiac events. This study will test whether losmapimod can safely reduce the risk of a subsequent cardiovascular event (such as death, heart attack, or near heart attack requiring urgent treatment ) when started immediately after ACS (specifically, heart attack). Patients who present with heart attack and qualify for the study will be randomly assigned to receive 3 months treatment with either losmapimod twice daily or placebo, which will be administered in addition to the usual standard of care therapies for heart attack. Following the in-hospital period, subjects will return for outpatient visits at 4 and 12 weeks, as well as a follow up visit at 24 weeks.
