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 a prospective, multi-center, single arm, non-randomized study to define safety and efficacy of the Veniti Vici™ Venous Stent System in relation to pre-defined Objective Performance goals. A maximum of 200 patients at up to 45 centers worldwide will be enrolled. Thirty (30) feasibility patients will be enrolled at approximately 7-10 centers and 170 pivotal patients will be enrolled at approximately 45 centers worldwide. The follow-up period is 36 months.
The purpose of this study is to determine whether fostamatinib is safe and effective in the treatment of IgA Nephropathy
The objectives of this study is to assess the characteristics and frequency of adenovirus conjunctivitis in a population of male and female patients from one year of age who present signs and symptoms of acute conjunctivitis.
This study is a prospective, multi center, randomized, controlled study of the VasQ in arteriovenous fistulas. The VasQ constraints and directs the geometrical parameters of the fistula as well as the vascular diameter and gradient in the vicinity of the AV shunt. These geometrical constraints direct flow and influence hemodynamics, and hence minimize turbulence and promote laminar flow. The device is designed to improve short term maturation and long term patency of the fistula. The VasQ is a permanent implant intended for use as a subcutaneous arteriovenous conduit support for vascular access.
The purpose of this study is to determine the absolute bioavailability of 150 mg oral dose of BMS-791325 relative to 100 µg IV infusion of [13C]-BMS-791325.
The VIABLE study sought to confirm the hypothesis that the combination of docetaxel with DCVAC/PCa followed by a maintenance therapy with DCVAC/PCa would improve overall survival in patients with metastatic castration-resistant prostate cancer.
The purpose of this study is to evaluate the efficacy and safety of rivaroxaban compared with placebo in the prevention of symptomatic venous thromboembolism (VTE) events and VTE-related death post-hospital discharge in high-risk, medically ill patients.
Egg allergy is common in early childhood, affecting at least one in 50 preschool children. Influenza ("'flu") vaccines contain egg protein, as the vaccine is cultured in hen's eggs. There is robust data to support the safety of influenza vaccines (containing low or negligible amounts of egg protein) in patients with egg allergy. A new influenza vaccine, known as LAIV (Live Attenuated Intranasal Vaccine) has recently been approved by a number of licensing boards and is given by a spray into the nose. This new vaccine has been available in the United States for several years and is highly effective and against influenza infection, with an excellent safety profile in children without egg allergy. However, LAIV is also grown in hen's eggs and contains egg protein, and there are NO published data on the safety of LAIV in egg-allergic children. In SNIFFLE 1 Study, 433 doses were given to 282 egg-allergic children; data is currently being analysed. The objective of this multicentre study is to further assess the safety of intranasal LAIV in egg-allergic children, in order to demonstrate that these children can safely be given the new LAIV within a primary care health environment.
Haemorrhage following major trauma is an important preventable cause of death. Those patients who survive may have a prolonged period of debility caused by failure of key body organs. We suspect that an important contributor to this organ failure may be dysfunction in the network of small blood vessels that supply the bodies organs with oxygen and nutrients. Our study will examine the link between the microcirculation and organ failure in patients who have suffered significant bleeding after traumatic injury. We will also explore the relationship between resuscitation of the global circulation (blood pressure, cardiac output etc.)an area that is monitored in clinical practice with the state of the microcirculation, which by contrast is not monitored. Patients with severe traumatic injury commonly have problems with blood clotting. Some researchers have suggested that microcirculatory failure may be an important contributor to this problem and we will explore this in more detail. Finally, we will attempt to examine some of the mechanisms by which the microcirculation may be disrupted by trauma and subsequent bleeding. These may include inappropriate activation of white blood cells, inadequate function of oxygen carrying red blood cells and changes to the cells lining the small blood vessels. We will use a non invasive method to assess the microcirculation termed Side Stream Dark Field microscopy. This involves recorded a video image of the movement of blood within the small blood vessels under a patients tongue. In addition we will use ultrasound to assess the flow of blood from the heart. Small samples of blood will be taken to assess blood clotting and to look at possible mechanisms of microcirculatory dysfunction. We aim to study ten patients in the first instance. The study will be carried out within the intensive care units at Kings College Hospital.
Carbohydrate is stored in the body as glycogen, which is mainly found in the liver and muscle. During endurance exercise, muscle glycogen is used as fuel for the working muscles and liver glycogen is broken down to provide glucose to maintain blood glucose (sugar) levels. Both liver and muscle glycogen are important for the ability to perform intense/prolonged endurance exercise. Therefore, nutritional strategies which can maximise the availability of glycogen in muscle and liver can benefit endurance exercise capacity. The carbohydrates typically found in sports drinks are glucose and sometimes fructose. If glucose only is ingested during exercise, then the maximum rate at which can be absorbed from the intestine into the blood stream is ~1 g/min. However, if different sources of carbohydrate (fructose) are used, which are absorbed through a different pathway, absorption of carbohydrate can be up to ~1.8 g/min. With more carbohydrate available as a fuel, this translates into an improvement in performance. Sucrose is a naturally occurring sugar that is made up of a single glucose and single fructose molecule. Therefore, theoretically, this can use the two different pathways of absorption and also maximise carbohydrate delivery. It is not yet known however, what impact this has on our liver and muscle glycogen stores during exercise. Therefore the aim of this study is to assess whether sucrose ingestion influences liver and muscle glycogen depletion during endurance exercise.
