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.
In the last forty years the prevalence of asthma has increased in westernised countries. We have hypothesised that this increase may be a consequence of changing diet. Several birth cohort studies have now reported an association between reduced maternal vitamin E intake during pregnancy and childhood asthma. However, it remains to be seen whether increasing maternal vitamin E intake during pregnancy reduces the risk of childhood asthma. We are planning a large placebo controlled trial in pregnant women, to investigate whether optimisation of dietary vitamin E intake to the recommended 15mg/day reduces the likelihood of childhood asthma. We believe that a dietary intervention using vitamin E in its natural form of food is more likely to be successful and acceptable than a vitamin E supplement. We have previously demonstrated than pregnant women can optimise their vitamin E intake using a personalised dietary plan with the help of a dietitian however this intervention was complex and could not be translated into everyday use. With commercial support we have developed a range of soups containing foods naturally rich in vitamin E designed to optimise maternal vitamin E intake to 15mg/day. A range of similar tasting and looking placebo soups has also been developed. In this study we will pilot a randomised controlled trial of the active and placebo soups to ascertain whether pregnant women are willing and able to optimise their vitamin E intake during pregnancy using the soups in order to reduce the risk of their child developing asthma. optimising maternal vitamin E intake during pregnancy.
Vegetarians are known to be deficient in vitamin B12, due to a lack or absence of dietary animal produce, which can elevate homocysteine. There is strong evidence indicating that elevated plasma total homocysteine (tHcy) is a contributor to chronic conditions, such as primary cardiovascular disease (CVD). The study hypothesis is: There will be a significant decrease in plasma tHcy of vegetarians following the intervention by supplementary vitamin B12 (of the methylcobalamin type) and this will lead to a reduction of the risk of CVD.
RV568 is being developed as a possible treatment of smoking related lung disease (also known as Chronic Obstructive Pulmonary Disease - COPD). The main purpose of this study is to examine the safety and tolerability of a new inhaled formulation of RV568 in healthy volunteers. The study will be run in two parts; Part A and Part B. Part A (Cohorts 1, 2 & 3) will investigate 6 different dose levels of RV568 given as a single dose and Part B (Cohorts 4 & 5) will investigate 2 different dose levels of RV568 given once a day for 14 days.
Patients who have myocardial injury after noncardiac surgery are at a higher risk of dying than those who do not. One in 10 patients with myocardial injury will die within 30 days of surgery. This risk of death exists up to one year after myocardial injury. There are currently no treatments or guidelines available for heart injury after surgery, but there is evidence that taking a blood-thinner can prevent some of the deaths, both in the short and long-term. The purpose of this trial is to test the effect of two drugs (dabigatran and omeprazole) that may prevent mortality, major cardiovascular complications and major upper gastrointestinal bleeding in patients who have had myocardial injury after noncardiac surgery.
Patients with stable chest pain presenting to general practitioners in UK are routinely referred to the chest pain clinics in the hospitals. They are assessed by clinical history including risk factors, cardiovascular exam, resting ECG, chest x-ray, and exercise ECG. CT calcium scoring (CTCS) is a technique that is very sensitive in identifying and quantifying calcified atherosclerotic plaques. Recent guidance from the National Institute of Clinical Excellence (NICE, citation 1) proposes the use of CTCS in patients with stable chest pain who have low likelihood of coronary artery disease (CAD). They recommend that patients with low likelihood (10-30%) have a CTCS and if the score is 0, they can be considered to have non-cardiac chest pain. However, there is controversy regarding relationship of absent calcification with significant CAD and its prognostic value. At our institution, we have been performing CTCS in this patient cohort since 2003. We plan to retrospectively review the usefulness in CTCS in patients with different likelihood for significant CAD, particularly in patients with absent calcium and compare with the traditional assessment. We also plan to follow-up these patients for any myocardial infarction and death from any cause.
The objective of the study (part A) is to evaluate the efficacy and safety of BAY80-6946 in patients with indolent or aggressive Non-Hodgkin's Lymphoma, who have progressed after standard therapy. 30 patients will be enrolled to both indolent and aggressive disease group. The objective of the study part B (CHRONOS-1) is to evaluate the efficacy and safety of BAY80-6946 in patients with relapsed/refractory follicular lymphoma. 120 patients will be enrolled in the part B of the study. Further objectives are to evaluate the pharmacokinetics and biomarkers. Quality of life will be a further objective of part B of the study. In a cohort of 20 patients (enrolled both in part A and B) an ECG substudy will be performed to assess the potential for cardiac toxicity and QT/QTc interval prolongation of BAY80-6946. After an up to 28-day screening period, eligible patients will start treatment with BAY80-6946 at a dose of 0.8 mg/kg (Part A) and at a dose of 60 mg (Part B). Treatment will be continued until disease has progressed or until another criterion is met for withdrawal from study. An end-of-treatment visit will be performed within 7 days after discontinuation of study treatment. Thirty to 35 days after last study drug administration, a safety followup visit will be performed for the collection of adverse events (AEs) and concomitant medication data. Patients will be contacted quarterly to determine overall survival status up to 4 years after last patient completed treatment. Patients who discontinue study drug for reasons other than disease progression will enter the Active Assessment Follow-up period. The end of study notification to Health Authorities will be based on the completion of the collection of survival data. The efficacy is measured by the decrease in tumor size. Tumor assessments will be done at Screening, every 8 weeks during Year 1, every 12 weeks during Year 2, and every 6 months during Year 3. Blood samples will be collected for pharmacokinetic analysis. Archival tumor tissue and blood samples will be collected for biomarker analysis (mandatory) and for central pathology review (part B), fresh biopsy tissue will also be collected if available.
Subclinical hypothyroidism (SCH) is a common condition among older men and women. Although by definition SCH comprises biochemically mild thyroid hormone deficiency without overt symptoms, it is a possible contributor to multiple problems in older age. Thyroid hormone has effects on numerous physiological systems, including the vascular tree, heart, skeletal muscle and brain. Therefore, thyroxine substitution to overcome thyroid hormone deficiency has the potential to give multisystem benefits to older people with SCH. Small studies have reported reduced atherosclerosis and improved heart function with thyroxine replacement, but no large clinical trials have been performed. Therefore the available evidence is limited, leading to major variations in guidelines and clinical practice, with uncertainty regarding the indications for screening and treatment. The investigators propose a multicentre randomised placebo controlled trial to assess the impact of thyroxine replacement in a minimum of 540 older adults (maximum 750) with persisting SCH (excluding those in whom it is a temporary phenomenon who are unlikely to benefit). The investigators will include older men and women with a wide age range and of varying health status. Outcomes include health related quality of life, muscle strength, executive cognitive function and cardiovascular events, with a minimum of 1 year of follow up. Blood and urine samples will be stored in a biobank, to allow future research on causes of ill health in older people with SCH. The investigators have the support of patient advocacy groups and a consortium with the wide range of expertise and experience required to conduct large scale multicentre clinical trials. The proposal explores the multisystem and quality of life benefits to older people of a tailored approach to management of SCH. This clinical trial should definitively clarify whether thyroxine treatment for SCH provides benefits that are relevant for patients. This trial will provide strong evidence with the potential to improve clinical practice, reduce health care costs and promote healthy ageing of older adults.
The purpose of the REVERSE Post Approval Study (PAS) is to confirm the benefit observed in the REVERSE and RAFT pivotal studies in "real-world" clinical practice.
This is a double-blind, placebo-controled, randomized trial to investigate if aspirin pre-treatment has anti-inflammatory effects in a model of acute lung injury induced by inhaled endotoxin (LPS) in healthy human volunteers.
The primary objective of the study is to evaluate the safety and tolerability of tirabrutinib (formerly ONO/GS-4059) given as monotherapy to participants with relapsed/refractory non-Hodgkin's lymphoma (NHL) and chronic lymphocytic leukemia (CLL).
