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 this study is to evaluate the effectiveness of enzalutamide in patients with metastatic castration resistant prostate cancer (mCRPC) in the clinical practice setting as measured by time to treatment failure defined as the time from baseline (treatment initiation) to treatment discontinuation of enzalutamide for any reason including disease progression, skeletal related events, treatment toxicity, patient preference, or death.
Muscle size declines at around 0.5-1% per year after 50 years of age, with muscle strength declining up to twice as fast as muscle size. This may eventually lead to loss of independence if tasks of daily living become too strenuous to be performed safely. Short periods of bed rest cause very rapid loss of muscle size and strength, and studies using healthy older participants have shown that age increases vulnerability to this muscle loss. However, it is unlikely that healthy individuals would be faced with periods of bed rest unless suffering a severe illness. In light of this, recent evidence has shown that even just reducing walking to less than 1,500 steps per day for two weeks caused 4% loss of leg muscle in over 65 year olds. This amount of activity is roughly the equivalent of being housebound, something that may become more common into older age, for example due to prolonged bad weather, or minor injury or illness. This study will investigate what causes such stark muscle loss during two weeks of reduced activity, and the impact on skeletal muscle function and size, as well as balance, body composition, and other indicators of general health such as how the body responds to food or exercise. Importantly, exercise strategies that could reduce muscle loss during a period of reduced activity will also be investigated. In brief, three groups of 10 older men (aged 65-80 years) will undertake two weeks of reduced physical activity by limiting their daily steps to <1,500/day. All groups will then undertake a re-training exercise programme to ensure that any losses in muscle strength or size are regained. One of the groups will be a control, whereby they will undertake the step-reduction intervention and re-training, but no protective exercise before or during the step-reduction intervention. This group will allow us to achieve our primary objective of determining the influence of two weeks of reduced physical activity on muscle strength and size in healthy older males. The two other groups will undertake either four weeks of strength exercise training before the step-reduction intervention, or daily home based exercise 'snacking' during the step-reduction intervention. The potential protective benefits of the exercise interventions in reducing the impact of two weeks of reduced activity on muscle strength and size, and any effect on how muscle is re-gained afterwards, will be compared to the 'control' group.
Vitamin D insufficiency has become a global concern, with low vitamin D status associated with bone disorders, cardiovascular disease and certain cancers. The United Kingdom (UK) and Ireland are at particular risk of vitamin D deficiency owing to the northerly latitude, increased use of sunscreen, decreased sun exposure and a high level of cloud cover. A recent survey in the UK showed that more than 50% of UK adults have insufficient vitamin D status, with lower levels noted in the winter months. Variations in vitamin D status have been known to vary between summer and winter, owing to our northern latitude (52-55°N) the Ultraviolet (UV)-B intensity in Northern Ireland is inadequate to promote the dermal synthesis of vitamin D during the winter months, causing us to rely on dietary sources. The aim of this intervention is to investigate the main effects of vitamin D3-fortified milk and supplemental vitamin D3 on vitamin D status and functional health outcomes during the winter, and how this intervention will affect subsequent dermal synthesis of vitamin D from UV exposure. Participants will be recruited from the local community. Blood samples will be collected from each participant at two timepoints (September/October and March/April). Pre- and post-intervention blood pressure, grip strength, height, weight, waist and hip circumferences will be measured, in addition participants will undergo a dual energy x-ray absorptiometry (DXA) scan to assess body composition and bone mineral density. Information on general health, lifestyle, physical activity, dietary intake and typical behaviours in the sun will be collected. Following the dietary intervention, a subset of participants will be invited to participate in a follow-up study, examining UV exposure during the summer months, when they will wear a personal wrist dosimeter for 1 month, complete a sun dairy and provide 2 additional blood samples.
This study is designed to evaluate the efficacy and safety of MED2005, a topically applied glyceryl trinitrate (GTN) gel administered to the penis of male subjects self-diagnosed with erectile dysfunction (ED) immediately before sexual intercourse.
The aim of volume replacement is to compensate a reduction in the intravascular volume e.g. during surgery and to counteract hypovolemia in order to maintain hemodynamics and vital functions. So far, there is only few data on the safety and efficacy of the products under investigation in children. The primary aim of this non-interventional observational study (NIS) is to collect further data of gelatine solutions in a large pediatric population during routine clinical practice.
This is a clinical trial in which healthy volunteers will be administered two experimental Ebola vaccines: ChAd3-EBO-Z and Ad26.ZEBOV. Four groups of volunteers will be vaccinated with both vaccines one after the other in a prime/boost regimen. All ChAd3-EBO-Z doses are 1x10^11 vp and all Ad26.ZEBOV doses are 5x10^10 vp. Group 1 will receive a ChAd3-EBO-Z priming vaccine and an Ad26.ZEBOV boosting vaccine 28 days later. Group 2 will receive an Ad26.ZEBOV priming vaccine and a ChAd3-EBO-Z boosting vaccine 28 days later. Group 3 will receive a ChAd3-EBO-Z priming vaccine and an Ad26.ZEBOV boosting vaccine 56 days later. Group 4 will receive an Ad26.ZEBOV priming vaccine and a ChAd3-EBO-Z boosting vaccine 56 days later. The study will assess the safety of the vaccinations, and the immune responses to vaccination. Immune responses are measured by tests on blood samples. The ChAd3-EBO-Z and Ad26.ZEBOV vaccines are called viral vectored vaccines. They are made from viruses which are modified so that they cannot multiply. The viruses have extra DNA in them so that after injection, the body makes Ebola proteins (but Ebola does not develop), so that the immune system builds a response to Ebola without having been infected by it. Healthy volunteers will be recruited in Oxford and London, England. The study will be co-funded by GSK Biologicals and Crucell Holland BV.
This study will evaluate the safety, tolerability, and pharmacokinetics of the combination of rhuMab 2C4(Perjeta) and capecitabine (Xeloda) in participants with advanced solid tumors that have progressed during or after standard therapy, or for which no standard therapy is available. Participants will be enrolled and evaluated for dose-limiting toxicities (DLTs) in escalating-dose cohorts in order to determine the maximum tolerated dose (MTD).
Mucopolysaccharidosis type IIIB (MPS IIIB, also known as Sanfilippo Syndrome Type B) is a severe neurodegenerative disorder. The purpose of this study is to learn more about the health problems in patients with MPS IIIB and how to measure these problems over time. It will particularly look at how the disease develops in young children. This is an observational study, so no experimental drug will be given. The results from this study will help us design future studies to measure whether these health problems get better when we give experimental drug for MPS IIIB.
The purpose of the protocol is to demonstrate the safety and the efficacy of a single injection of a new formulation of Clostridium Botulinum toxin type A haemagglutinin complex (BTX A HAC NG) to improve the appearance of moderate to severe glabellar lines (the lines between the eyebrows) and to assess the long term efficacy and safety of BTX-A-HAC NG after repeated injections.
Recessive dystrophic epidermolysis bullosa (RDEB) is a severe form of blistering skin disease caused by mutations in COL7A1 gene. This study aims to assess the safety of intradermal injections of gene-modified autologous fibroblasts in 5-10 adults with RDEB.
