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 an open label, long term extension to Study AMB115811. All subjects may remain in the extension study for a minimum of 18 months. Beyond the 18-month period, subjects may continue in the extension study until one of the following: - The product is approved locally for use in inoperable CTEPH patients; - Development for use in the CTEPH population is discontinued or product is not approved by the local regulatory authorities - The investigator decides to discontinue the subject or subject decides to discontinue from the study. The primary purpose of this study is to provide clinically relevant information on the long term safety of ambrisentan in subjects with inoperable CTEPH.
The airways in the lungs get smaller the further into the lungs they go. Most simple measurements of lung function only reflect the larger 'central' airways and do not provide information on the smaller 'peripheral' airways. Newer measurements have been developed that can now give us accurate information on how the smaller airways are working. Indeed the small airways seem to play a significant role in asthma in terms of inflammation and airway narrowing. Recently, new types of inhaler formulations have been developed that have a much smaller particle size than other standard formulations. These formulations have been shown to go further into the lungs, thus getting into the smaller airways. In this study we aim to compare the two extremes of available long acting beta agonists in terms of particle size i.e. extra fine formoterol (Atimos) versus coarse particle salmeterol (Serevent)in asthmatics with abnormal small airway function using a breathing test called impulse oscillometry. By using this test we will be able to find out whether using an extrafine particle inhaler improves small airway function.
Influenza morbidity and mortality cause a substantial financial burden to the NHS and to the UK as a whole. Influenza vaccine is safe and effective but is required annually because the circulating strain of virus changes each year. In the UK in 2012, the Chief Medical Officer (CMO) recommended that at least 75% of elderly people (aged 65+) and 75% people under 65 with certain chronic conditions (e.g. chronic heart disease, diabetes, asthma, etc) should be vaccinated. While primary care practices are achieving these targets for elderly patients, those set for younger patients with chronic conditions are not being met, with a third of patients being missed in the 2011/12 flu season and with no substantial improvements in uptake in the past decade. Therefore strategies to increase flu vaccine uptake in these patients are required. Previous trials have shown that patient reminders can increase vaccine uptake and in particular, text messaging has shown to work in some populations in the United States as a cheap, simple and effective reminder. However, whether the same is true in UK general practice is unclear. The use of text messaging in the NHS for appointment reminders is also increasing as it is cheap, quick and effective. Text messaging is already used in roughly 30% of practices to remind patients about their flu vaccine but there has been no trial addressing its effectiveness. Therefore, we propose a trial of a text messaging flu vaccine reminder in patients aged under 65 who have a chronic condition. We hypothesise that practices that send a text message will have increased flu vaccine uptake.
This study was designed as a 3-year extension to the phase III core study CAIN457F2306. It aimed to provide continuous treatment with secukinumab in pre-filled syringes (PFS) for subjects who completed the core study CAIN457F2306, to obtain further long term efficacy, safety and tolerability information in subjects with active psoriatic arthritis receiving secukinumab every 4 weeks. At Week 104 of the study CAIN457F2306, eligible subjects completed the assessments associated with the core study visit and subsequently continued in this extension study on the same dose that they were receiving during the core study. The regular assessments of disease activity ensure that subjects who are experienced worsening of disease in any of the treatment groups could exit the study upon their own wish or based on the advice of the investigator at any time.
This study is conducted in Europe and Asia. The purpose of the study (Diabetes Pregnancy Registry) is to evaluate the safety of treatment with insulin detemir in pregnant women with diabetes mellitus.
A double-blind randomised active-controlled trial aims to assess whether Cogmed (adaptive) working memory training results in improvements in untrained measures of cognition, speech perception and self-reported hearing abilities in older adults (50-74 years) with mild-moderate hearing loss who are existing hearing aid users, compared with an active placebo Cogmed (non-adaptive) control. It is hypothesised that improvements on trained Cogmed tasks, representing increased working memory capacity, will result in improved performance on cognitive and speech perception tasks that engage working memory. We also measure self-reported hearing ability to assess self-perceived benefit of Cogmed training.
The purpose of this study is to demonstrate equivalent efficacy of GP2015 and Enbrel® in patients with moderate to severe chronic plaque-type psoriasis with respect to PASI 75 response rate at Week 12.
The primary objective of the CORDIA study is to use an effective evidence-based self-management intervention (SMI) for type 2 diabetes, with and without a novel test to give a personalised genetic and lifestyle risk of coronary heart disease, to examine their capacity to reduce the risk of coronary heart disease (CHD) and improve diabetes management in primary care patients with type 2 diabetes. The effect of these interventions on clinical, behavioural and psychological outcomes will be investigated.
- Observe the long-term (1-year) outcomes of Dermagraft, compared with conventional treatment of four-layer compression bandaging therapy alone, in subjects who completed the ABH-Dermagraft-001-08 study. - Study Hypothesis: N/A (Long-term follow-up study)
The CONSORT (Consolidated Standards of Reporting Trials) Statement aims to improve the reporting of randomized trials. If trials are not well reported it is difficult for clinicians to use best evidence to inform clinical practice and patients may not get the best care. A number of different CONSORT extensions have been developed which specify additional information needed for more complex trials. The aim of this project is to evaluate whether using a simple web-based tool (WEBCONSORT) improves the reporting of clinical trials. The tool combines different CONSORT extensions and allows authors to obtain a checklist and flow diagram which is specific to their individual trial. In this study authors of participating journals are requested, at the manuscript revision stage, to use a web-based tool to improve the reporting of their randomized trial. Authors registering to use the tool are randomized to intervention or control. In the intervention group authors are directed to the WebCONSORT tool. In the control group, authors are directed to a different version of the WebCONSORT tool which includes the flow diagram part of the tool but not the main checklist or elements relating to CONSORT extensions. The aim is that this tool should lead to improvements in the reporting of randomized trials, making it easier for clinicians to read and interpret published findings.
