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 purpose of the study is to look at the levels of an HIV medication (raltegravir) in the blood, and how it is affected if raltegravir is taken at the same time as another medicine for high blood pressure (amlodipine). Many patients with HIV will also have high blood pressure, so it is important to know which drugs for each of these conditions can be taken together without affecting how well they work individually. Over a 3 week period, participants took amlodipine for 2 weeks, and raltegravir for 2 weeks, with the middle week being on both drugs. The investigators will look at and compare the levels of these two drugs in the blood after subjects have taken them separately and both together. This study is randomised into two groups with both study medications received by all participants in a three-period crossover pattern; randomisation determined which medication was taken first. Once randomised allocation was performed, medications were administered in an open-label fashion.
The rise in the prevalence of type 2 diabetes is related to recent lifestyle changes leading to a rise in obesity. Obesity is a risk factor for Impaired Glucose Tolerance (IGT) and diabetes. A type of fibre - fermentable carbohydrate - may help prevent diabetes in individuals with IGT by reducing appetite and food intake, and improving insulin sensitivity. Although fermentable carbohydrate is not absorbed in the small intestine it is full fermented by the colonic bacteria. The fermentation of this carbohydrate produces short chain fatty acids which act on specific G protein coupled receptors (GPR41/43) in the intestine to release GLP-1 and PYY. GLP-1 and PYY are hormones which act on appetite centres in the brain to decrease appetite. GLP-1 incretin effects and possible effect of the beta cell will increase insulin sensitivity. Short chain fatty acids also suppress the release of free fatty acids from adipocytes. Lower levels of free fatty acids in insulin resistant subject's leads to improved insulin sensitivity. This body of work will examine the effect of fermentable carbohydrate on appetite, weight loss, blood glucose control which will give an indication of the possibility of fermentable carbohydrate to prevent type 2 diabetes in this at-risk group.
The purpose of this study is to determine the optimal biological dose (OBD) of Irosustat (BN83495) in postmenopausal women with oestrogen receptor (ER) positive locally advanced or metastatic breast cancer with disease progression after prior hormonal therapy. This study is designed to provide necessary information on safety and dose response of BN83495, when given by repeated once daily oral administration, while achieving a maximal STS inhibition and a maximal reduction in plasma oestradiol (E2) and adiol levels. The data obtained will be used to plan further clinical studies.
The purpose of this study is to determine whether renal sympathetic denervation (RSD)(a treatment that lowers the activity of the sympathetic nervous system) is useful in the management of patients with heart failure with preserved ejection fraction (HF-PEF).
The Valiant Mona LSA thoracic stent graft system is for the endovascular repair of aneurysms of the descending thoracic aorta (DTA) in patients who require coverage of the left subclavian artery (LSA).The study is intended to assess safety and performance of the device acutely and at 30 days.
This study is an exploratory randomized controlled trial (RCT) of a group psychological intervention for postnatal depression in British mother's of south Asian origin. The aim is to evaluate the efficacy of a group psychological intervention (PHP) based on the principles of Cognitive Behaviour Therapy in treating depression in postpartum women. The hypothesis is that depressed British women of South Asian origin receiving the group intervention will show significant improvements in terms of severity of depression as compared to the treatment as usual (TAU) control group.
To evaluate the maintenance of efficacy and safety during long-term treatment with brexpiprazole as an adjunctive treatment for adult subjects with Major Depressive Disorder (MDD)
Evaluation of the best therapeutic index for patients with platinum-sensitive ovarian cancer when treatment with bevacizumab and gemcitabine/carboplatin or with bevacizumab and PLD/carboplatin.
Angiogenesis and fibrosis lie at the heart of a number of fundamental processes responsible for cardiovascular disease. In this proposal, the investigators intend to build upon a highly successful programme of studies exploring the cardiovascular applications of positron emission tomography. Specifically, the investigators will explore the potential role of a novel radiotracer, 18F-fluciclatide, which is a highly selective ligand for the αvβ3 and αvβ5 integrin receptors that are up regulated during angiogenesis, and tissue fibrosis and remodelling. This tracer has been successfully used to assess angiogenesis in metastatic tumours and its uptake is suppressed by anti-angiogenic therapies. The investigators here propose to describe the pattern of uptake of 18F-fluciclatide in cardiovascular diseases, specifically aortic stenosis and aortic atherosclerosis. The investigators will correlate 18F-fluciclatide uptake with in vivo measures of angiogenesis and fibrosis as well as ex vivo histological characterisation of tissue. If successful, this novel radiotracer could provide an extremely important non-invasive method of assessing in vivo angiogenesis, plaque vulnerability, and tissue remodelling as well as potential applications in developing stem cell therapies.
