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 EMINENT study is a prospective, multi-center study confirming the superior effectiveness of the ELUVIA stent versus Self-Expanding Bare Nitinol Stents in the treatment of lesions in the femoropopliteal arteries.
Fixed orthodontic braces are routinely used to straighten teeth and correct the bite of individuals. Once the braces are fit, the patient is recalled every few weeks to adjust or tighten the brace. Although convention states that the patient returns every 6-8 weeks to have the brace adjusted, there is no consensus or evidence to support a specific timeframe. Indeed some orthodontist see their patients as frequently as every 4 weeks and others as long as every 10 weeks. The aim of this investigation is to determine whether the amount of time between brace adjustment appointments has an effect on the overall treatment time. Knowing which appointment interval will lead to the shortest overall treatment time will be of benefit to patients as prolonged orthodontic treatment may be associated with an increased incidence of adverse effects associated with orthodontic treatment. Patients who are to be treated with fixed orthodontic braces at will be invited to take part in the study. Consenting subjects will be randomly allocated into one of four groups. The first will be seen to adjust their brace every 4 weeks, the second group every 6 weeks, the third group every 8 weeks and the fourth group every 10 weeks. The primary outcome measure is the total treatment time. The mean treatment time of each of the four groups will be compared to establish whether or not treatment appointment intervals affects treatment time. Secondary outcome measures will include difference in number of appointments required throughout the course of treatment between groups, differences in treatment outcomes, differences in patient compliance.
The primary objective of this study is to observe the long-term safety of filgotinib in adults who have completed or met protocol specified efficacy discontinuation criteria in a prior filgotinib treatment study in ulcerative colitis (UC).
This project will investigate the synergistic effects of Aerobic and Resistance type Exercise, in combination with Protein Supplementation, on; Body Composition, Musculoskeletal Functioning, Nutritional Status and Quality of Life in Age-related Sarcopenia.
The Primary purpose of this study is to identify the recommended Phase 2 dose [RP2D(s)] for JNJ-63723283 in Part 1, to assess the anti-tumor activity of JNJ-63723283 at the RP2D(s) in participants with selected advanced cancers including non-small-cell lung cancer (NSCLC), melanoma, renal, bladder, small-cell lung cancer (SCLC), gastric/esophageal cancer, and high-level microsatellite instability (MSI-H) or mismatch repair-deficient (dMMR) colorectal cancer (CRC) in Part 2, to determine one or more additional RP2Ds in Parts 3 and 4.
This is a Phase III, double-blinded, placebo-controlled, randomized, multicenter study designed to evaluate the efficacy, safety, and pharmacokinetics of atezolizumab + cobimetinib + vemurafenib compared with placebo + cobimetinib + vemurafenib in patients with previously untreated BRAFv600 mutation-positive metastatic or unresectable locally advanced melanoma.
The current study will investigate the effect if whey protein on postprandial glycaemia and appetite in type II diabetics, assessing incretin (GLP-1, GIP), insulin, and appetite control (leptin, PYY3-36) hormone responses.
A randomised controlled trial to compare two strategies for the investigation of coronary artery disease at the time of angiography. Patients will be randomised to conventional angiography or additional, routine pressure wire assessment - measuring fractional flow reserve (FFR) - in all main vessels judged as being of sufficient vessel calibre to allow percutaneous coronary intervention (PCI) (experimental arm).
The Investigators hypothesise that asthma is not a single disease, but a syndrome resulting from several distinct underlying disease processes known as endotypes. There are approximately 30,000 genes in humans, and each gene is responsible for the production of a particular protein. Using a technique called "whole genome expression profiling" The Investigators have undertaken a small study looking at the activity of all 30,000 genes in the airway tissue of people with asthma. This work has identified 3 mutually exclusive distinct molecular patterns (endotypes) of severe asthma and has identified other potentially important molecular targets (manuscripts in preparation). In particular,the Investigators have found that 25-50% of patients have asthma associated with the activity of proteins called Th2 cytokines (Th2-high asthma). New treatments are in development that target this pathway. However, the Investigators do not know what is driving severe asthma in patients who do not express these Th2 cytokines. The aim of this study is to investigate in more detail the molecular mechanisms driving severe asthma in patients who do not express Th2 cytokines (Th2-low asthma), so that the Investigators can identify new targets for treatment in this group. To do this the Investigators will collect airway tissue via a telescope (bronchoscope), and analyse gene and protein expression in the tissue. The Investigators will then compare the molecular activity between patients with Th2-high and Th2-low asthma, and healthy control subjects (data obtained from a parallel study).
