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 study will be conducted to demonstrate, using polysomnography, that lemborexant 10 milligrams (mg) and 5 mg is superior to placebo on objective sleep onset as assessed by latency to persistent to sleep (LPS) after the last 2 nights of 1 month of treatment in participants 55 years and older with insomnia disorder.
The purpose of this study is to evaluate potential biomarkers and method of action, efficacy and safety of olaratumab in participants with soft tissue sarcoma (STS).
In 1997, the global prevalence of diabetes was estimated to be 125 million and this has risen to around 400 million in 2015. In addition diabetes has a number of complications including heart disease, blindness, kidney failure and amputation. This represents a significant burden on healthcare services. Type 2 diabetes (T2D) is caused by a combination of genetic and environmental factors. The aim of GoDARTS is to recruit participants with T2D to a registry to provide a platform with which to investigate the genetics of T2D, its complications and response to treatment. This study will investigate the genetic basis of diabetic neuropathic pain.
Primary Objective: To determine the effect of avalglucosidase alfa treatment on respiratory muscle strength measured by percent (%) predicted forced vital capacity (FVC) in the upright position, as compared to alglucosidase alfa. Secondary Objective: To determine the safety and effect of avalglucosidase alfa treatment on functional endurance (6-minute walk test, inspiratory muscle strength (maximum inspiratory pressure), expiratory muscle strength (maximum expiratory pressure), lower extremity muscle strength (hand-held dynamometry), motor function (Quick Motor Function Test), and health-related quality of life (Short Form-12).
The study is a pilot study of Cognitive therapy for people with psychosis who have distressing visual hallucinations. The aim is to evaluate whether this is an acceptable, feasible and effective treatment. This is a pilot study and there is no randomisation to either CBT or treatment as usual (TAU). If a participant is allocated to the cognitive therapy plus TAU condition then the participant will meet with a therapist on initially a weekly basis and receive up to 8 sessions of CBT over a 2 month period. The participant will also have regular assessments conducted by a researcher who is independent to the treatment group. It is predicted that those people receiving CBT will improve on measures of symptoms, and particularly for measures of visual hallucinations.
Anal Acoustic Reflectometry (AAR) is a reliable and reproducible technique that has been studied in our department over the last 6 years. Sound waves pass into a balloon placed in the anal canal and are used to measure the cross-sectional area. By gradually increasing and decreasing the pressure in the balloon the investigators can measure the pressure at which the cross-sectional area starts to increase and decrease, and the anal canal starts to open and close. This assessment mimics the natural opening and closing of the anal canal and the effect of squeezing the muscles. The gold standard investigation of the anal sphincter muscles has been manometry which measures anal canal pressure at rest and during squeeze. However, it has limitations. In previous studies AAR has shown promise in the assessment of faecal incontinence and, that unlike manometry, it has been able to distinguish between different types of incontinence. The Recto-anal Inhibitory Reflex (RAIR) is a normal response when the rectum fills with faeces, fluid or air, whereby there is a change in the pressures within the anal canal to determine the type of contents. This can be absent or altered in patients who have difficulty in opening their bowels. The RAIR is currently measured by anal manometry using a 4.9mm catheter, resulting in an anal canal which is already partially opened prior to the measurement, and potentially distorted. AAR is considered a catheter free technique as the balloon has a cross-sectional area of only 0.4mm2 when collapsed. The investigators propose to measure the RAIR using a 1.7mm diameter catheter alongside the AAR balloon to determine the effect that its placement has on the recorded parameters of AAR. This aims to improve our understanding of the opening and closing of the anal canal in response to distension of the rectum.
Anal Acoustic Reflectometry (AAR) is a technique that has been studied in our department over the last 6 years.

This assessment mimics the natural opening and closing of the anal canal and the effect of squeezing the muscles. The gold standard investigation of the anal sphincter muscles has been manometry which measures anal canal pressure at rest and during squeeze. However, it has limitations. Despite the two measurements being within the normal range, some patients can have significant faecal incontinence. This has prompted clinicians to search for a better investigation to guide the management of this condition. AAR is a reproducible and repeatable technique that has been used as a research technique in the assessment of faecal incontinence. It has been shown to correlate with symptom severity and, unlike manometry, is able to distinguish between different symptomatic subgroups with faceal incontinence. In our studies so far the investigators have increased the bag inflation pressure a step at a time which means that each study takes about 20 minutes to perform. The limitation of this method is that during the measurement of squeeze pressure the sphincter muscle is subject to fatigue. A recent study using the acoustic technique in the urethra has demonstrated a faster method of recording measurements over an 8 minute period. The investigators propose to study the fatiguability effects of this faster technique and validate the method against the existing step-wise technique and standard anal manometry. Patients will be randomised into two groups: 1. Stepwise then fast-fill 2. Fast-fill then stepwise
Chronic viral hepatitis often leads to liver scarring - cirrhosis. If the virus is eradicated from the liver, the liver scarring and liver function often recovers. In some patients the damage is too severe and recovery does not take place. It is not yet known which patients have liver disease that is too advanced to benefit from therapy nor is it known how fast the recovery occurs. Non-intrusive dynamic liver testing (DLT) may allow us to predict the functionality of the liver post treatment and may guide us in treatment choices - for example patients who are predicted not to recover may be prioritised for transplantation. Indocyanine green (ICG) is a dye solely excreted by the liver into bile and used to measure its dynamic function. Transient elastography is similar to ultrasound and measures the degree of fibrosis within the liver. The investigators hypothesise that the use of non-intrusive dynamic liver testing pre-treatment, will allow us to delineate patients before therapy who will have functional liver recovery following viral eradication. The investigators hypothesise that monitoring changes in liver fibrosis and liver function in patients with historical viral clearance will allow an assessment of the likely speed of recovery of liver fibrosis and function - for example if all patients 5 years after treatment for viral hepatitis induced cirrhosis have 'normal' fibrosis and liver function scores the investigators will be able to conclude that recovery is complete within 5 years. The investigators will perform a study pre and post-treatment assessing liver function using non-intrusive dynamic liver testing in addition to currently-used 'liver function' scoring systems, in a multivariate analysis, to determine whether or not the investigators can identify patients who are will have functional liver recovery post therapy.

The primary objectives of this study are to evaluate the efficacy, safety, and tolerability of sofosbuvir /velpatasvir (SOF/VEL) fixed-dose combination (FDC) in participants with chronic hepatitis C virus (HCV) who have received a liver transplant.
