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 multicenter, single-arm study will evaluate the efficacy and safety of atezolizumab (MPDL3280A) in participants with PD-L1-positive locally advanced or metastatic NSCLC. Participants will receive an intravenous (IV) dose of 1200 milligrams (mg) atezolizumab (MPDL3280A) on Day 1 of 21-day cycles until disease progression. Eligible participants will be categorized in to three groups as follows: 1. Participants with no prior chemotherapy for advanced disease; 2. Participants who progress during or following a prior-platinum based chemotherapy regimen for advanced disease (2L+participants); 3. Participants who are 2L+ and previously treated for brain metastases.
To evaluate the efficacy and safety of 0.5 mg in adult patients with visual impairment due to macular edema (ME).
Capecitabine is a chemotherapy drug used to treat many types of cancer including bowel and stomach cancer. Unfortunately a side effect of this drug is that it causes heart problems including heart attacks. An alternative drug, called teysuno is used extensively in other countries instead of capecitabine and appears to have less of a bad effect on the heart whilst still killing cancer cells. This study will investigate the effect of these two drugs on the heart and blood vessels and will be the first of its kind in humans.
A double blinded randomised control trial comparing the differences between laparoscopic single incision versus multiple port bariatric surgery in morbidly obese patients (BMI>35). Single incision surgery is a new minimally invasive surgical technique requiring the surgeon to operate through one small single incision and is virtually scarless. The traditional laparoscopic approach to abdominal surgery is through multiple small incisions (4-7 ports) across the whole abdomen. This study seeks to identify the risks, benefits and costs of the adjustable gastric band insertion via single incision and multiple incision within the morbidly obese patient group.
The purpose of this interventional Phase IV study was to explore the ease of use of TIP and prevalence of microbial contamination of the T-326 Inhaler compared with TIS and colistimethate administered via nebuliser for the treatment of Cystic Fibrosis (CF) patients chronically infected with P. aeruginosa. It was anticipated that the data from this study would provide clinicians with further guidance on the relative differences between the speed and ease of use of these treatments as well as useful information on the prevalence of microbial contamination of the inhalation devices in "real world" use.
To evaluate the safety, efficacy and pharmacokinetics of nilotinib over time in the Ph+ chronic myelogenous leukemia (CML) in pediatric patients (from 1 to <18 years).
Currently available smoking cessation treatments help only about 15% of smokers to quit long-term. These treatments do not typically address the behaviours and sensations associated with the act of smoking (e.g. handling a cigarette, inhaling, taste and feel of smoke on the throat). There is evidence that these elements influence smoking behaviour and cessation. Electronic cigarettes (EC) are a new product with a strong potential to be a realistic behavioural replacement for smoking. Whilst EC deliver nicotine, their use does not involve tobacco combustion, which is the primary source of the many thousands of dangerous chemicals to which smokers of conventional cigarettes are exposed. Studies on EC products and users indicate there is little doubt that they are substantially safer than conventional cigarettes. The investigators plan to conduct a study one of the very first studies to test the effects of adding EC to standard care on long-term validated outcomes. Before launching such a large and demanding trial however, data are needed on what proportion of smokers would be interested in using EC and what compliance with EC use can be expected, and no data exist to inform how large a sample is needed. This pilot study would provide such data. A total of 200 smokers would be recruited at smoking cessation clinics in London and Prague. Half the smokers would be randomised to receive standard smoking cessation behavioural support and medication (standard care; SC), and half to receive SC plus EC. The EC group would receive a four week supply of EC. The outcome measures for the study would be smoking status at 4 and 24 weeks after the target quit date, EC use, acceptability, and adverse events.
This is a multi-centre, open-label long-term safety study of 100 milligram (mg) mepolizumab administered subcutaneously (SC) every 4 weeks for 12 months in addition to standard of care in subjects who have severe, refractory asthma and a history of eosinophilic inflammation. Subjects who completed either MEA115588 or MEA115575 will be offered the opportunity to consent for this study.
Despite considerable effort the optimal site to place a pacemaker lead at the time of pacemaker implant remains unclear. Historically pacemaker leads have always been inserted at the bottom (apex) of the heart. It is suggested that a lead placed at the apex is associated with an increase in heart rhythm problems and also heart failure (impaired pumping function). The top of the ventricle (septum) has been investigated as an alternative site and is now routinely used by some centres. Previous estimation of the hearts pumping function (ejection fraction) has been limited to the use of echo (sound waves). Echo is not sensitive enough to detect small changes in the ejection fraction reliably (measure of pumping function of heart). The gold standard for measurement of ejection fraction is MRI (using magnets). Previous pacemakers have not been compatible with MRI scans. The latest generation of pacemakers are now able to be safely scanned within an MRI scanner. This allows a much more accurate estimation of the effects of a pacemaker on the ejection fraction which has not yet been studied. The investigators plan to study those patients undergoing a pacemaker implant and ablation procedure as part of their standard care. Individuals will have an exercise test, blood test used to measure biomarkers and fill in a symptom questionnaire. Individuals will have a Cardiac MR compatible pacemaker fitted and 2 ventricular leads will be inserted, one apically and one septally. Only one lead will be used at any given time. Individuals will then undergo their planned AV node ablation. Following this they will have a cardiac MR scan. Further MRI scans will be performed at 9 and 18 month intervals, as will symptom questionnaires, blood tests (BNP) to determine heart muscle strain, exercise testing and echocardiograms. The hypothesis is that a lead placed on the septum will produce superior cardiac performance over the short and long term.
A lower rather than a higher glycemic load (GL) meal has been shown to benefit cognition and mood, however, the data in older adults and those most prone to cognitive dysfunction, is limited and conflicting. One explanation is that the GL of a meal may interact with a person's pre-existing glucose tolerance (GT). As older adults have a higher incidence of glucose tolerance and are more likely to experience memory problems the present study considers the interaction between the GL of meal in those with better or poorer GT. The population studied will not have a history of diabetes or dementia. A battery of cognitive tests will be administered after meals sweetened with one of three sugars known to vary in the rate that they release glucose into the blood stream.
