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 prospective study in which patients with castrate-resistant prostate cancer and bone metastases will undergo imaging, donate blood, bone marrow and urine samples, and where possible primary tumour and bone metastatic tissue, before and during treatment with ZD4054, an orally active specific endothelin-A antagonist. The samples will be used primarily for biomarker studies, and it is hypothesized that these will inform on the mechanism of action of this drug. Magnetic Resonance Imaging (MRI) will be performed to evaluate emerging functional imaging endpoints as markers of early response in bone metastatic prostate cancer.
This study is designed to investigate whether light therapy may be an effective treatment for some people with epilepsy. Light treatment is already an established treatment for depression. The chemical systems in the brain that are disrupted when someone becomes depressed, overlap with some of those that can be affected during some epileptic seizures. The investigators have designed this study to see whether light therapy may also lead to a decrease in seizures in people who have epilepsy. The study will be a placebo controlled trial. This means that half of the participants will receive a therapeutic dose of light therapy from a light box, whilst the other half will only receive a placebo light treatment.
This is a global study of tear osmolarity using the OcuSense TearLab technology to compare tear samples of age and sex-matched normals with those with Dry Eye Disease (DED). Diagnosis of DED subjects will be established using objective and subjective tests. Positive responses to 3 out of 6 defined criteria determine subjects with DED. DED subjects will be further categorized by severity, using results from the objective and subjective tests. Subjects will be assessed at a single visit.
Several large trials have shown that beta-blocker treatment reduces the risk of death and hospital admission in patients with symptomatic heart failure. Unfortunately, survey data suggests relatively poor utilisation of beta-blockers, despite ample evidence for good tolerability. Additionally there are several important unanswered questions, such as clinical efficacy for specific sub-populations (women, the elderly and patients with diabetes or other co-morbidities) and the effect of beta-blockers in combination with other medications. Previous meta-analyses, based on published tabular data, have been conducted although this approach has important biases and limitations. We plan to perform a carefully conducted systematic review of individual patient data from the major randomised trials of beta-blockers in heart failure. The goals of this collaborative project are to clarify the overall efficacy of beta-blockers and identify sub-groups that show particular benefit, thereby increasing the use of beta-blockers, reducing adverse clinical outcomes and the high costs associated with this condition.
The project has been designed to determine whether a brief period of leg ischemia will reduce the I/R injury sustained by the liver during liver surgery and liver transplantation. Adult patients (aged above 18) for liver resection (LR group) and for orthotopic liver transplantation (OLT group) will be analysed separately. Patients from each category will be randomised to two groups - a control and a Remote IPC group. In the remote IPC group Ischemic preconditioning will be induced during surgery by applying a pneumatic tourniquet to the upper part of the right thigh and then inflating it to twice the measured systolic arterial pressure in order to occlude the blood supply of the leg for 10 minutes. The tourniquet will then be deflated for 10 minutes to reperfuse the leg. This is repeated thrice to precondition the skeletal muscles of the leg.
Biliary atresia is a congenital disorder of bile duct development or destruction of established but immature bile ducts. The study tests the hypothesis that post-operative steroids improve outcome following the Kasai procedure - the commonest surgical treatment.
