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.
To assess the effect of the device on the progression of diabetic peripheral neuropathy
Primary: To examine the within subject variability of Clexane (80 mg) in healthy male and female volunteers administered subcutaneously (s.c.) as a single dose, in two periods, under fasting conditions. Secondary: To monitor safety during the Treatment Periods.
Randomized. double blind, placebo controlled, parallel arms dose finding study with a 4 weeks treatment period
Gastroesophageal reflux disease (GERD), a common chronic disorder in the veteran population, is associated with drug costs exceeding $ 10 billion/year. Only 30-40% of patients with reflux symptoms have erosive esophagitis. The vast majority suffers from non erosive reflux disease (NERD), a condition in which standard endoscopy fails to identify any mucosal breaks and is unable to confirm the diagnosis. Unfortunately, a gold standard for the diagnosis of NERD does not exist. Narrow band imaging (NBI) utilizes spectral narrow band filters (incorporated into standard endoscopes) and helps to see abnormal areas not identified during standard endoscopy. Preliminary results have shown that NBI endoscopy may represent a significant improvement over standard endoscopy for the diagnosis of NERD. The purpose of this study is to accurately diagnosis non acid reflux disease by using a blue light (also known as NBI)upper endoscopy technique.
The purpose of the study was to evaluate the efficacy of tapentadol oral solution, based on the total amount of supplemental opioid analgesic used over 12 hours or 24 hours after initiation of investigational medicinal product (IMP) in children and adolescents who had undergone surgery that would produce moderate to severe pain during opioid treatment.
This randomised, open-label, single-centre, descriptive study aims to investigate gene expression (i.e what genes are 'switched on' and 'off') following vaccination with 4CMenB and to relate this to vaccine reactions and to immune response. 160 healthy Caucasian infants aged 8-12 weeks (at time of first visit) who have not yet received their routine infant immunisations will be recruited. Participation in the study will be limited to to Caucasian infants (defined as having two Caucasian parents). This is so that baseline variability in gene expression data which is to some degree affected by ethnicity is reduced. Participants will be randomised to either a 'test' group or 'control' group depending on what 4CMenB schedule they receive, with 80 infants in each. All participants will receive the usual paediatric immunisations according to the UK national immunisation schedule. In addition, participants in the test groups will receive 4CMenB at 2, 4 and at 12 months while those in the control groups will receive the same vaccine at 5, 7 and 13 months. Blood samples will be taken from each infant at specified time points before and after vaccination to address the objectives of the study. In addition, oro-pharyneal swabs will be obtained around different vaccination timepoints to investigate the effect of 4CMenB vaccination on the oro-pharyngeal Neisseria microbiome.
The objective of the study is to assess the efficacy and safety of PerioChip® (Chlorhexidine gluconate chip) in the treatment of patients with Peri-implantitis. The hypothesis of the study is that PerioChip® in adjunct to mechanical subgingival debridement is more effective in the treatment of peri-implantitis when compared to the common method of mechanical subgingival debridement alone. The primary efficacy measure will be the reduction in probing pocket depth at 6 months as measured at sites of qualifying target implant.
The aim of this open label feasibility study is to determine recruitment rates to a randomised trial of glibenclamide compared with insulin (both in addition to maximum tolerated metformin) for the treatment of Gestational Diabetes Mellitus (GDM). This feasibility trial will inform the design of a future substantive multicentre trial to test the hypothesis that combination therapy with glibenclamide and metformin could reduce the number of pregnant women with GDM who require insulin and would be superior to metformin and insulin in terms of acceptability and cost effectiveness. Women with GDM who have "failed" monotherapy with metformin will be recruited and randomised to either receive glibenclamide (test arm) or standard care with insulin, both in addition to their maximum tolerated dose of metformin. Patients will be recruited from three of the antenatal clinics. This is a feasibility study in preparation for a large multicentre randomised trial to test the hypothesis that the addition of glibenclamide to metformin (combination therapy) could reduce the number of pregnant women with gestational diabetes mellitus requiring insulin, without compromising glycaemic control or other clinical outcomes. The investigators hypothesise that combination therapy with metformin and glibenclamide is likely to be preferable to metformin and insulin in terms of acceptability and cost.
This research study is designed to investigate the effects of a simple cognitive task (a memory reactivation cue following by playing the computer game "Tetris") on flashbacks and other post-traumatic stress symptoms after a road traffic accident. Patients presenting to a hospital emergency department soon after a road traffic accident will be randomly allocated to either the simple cognitive task intervention or usual care. Participants will be followed up at one week and one month. It is predicted that participants given the simple cognitive task intervention will develop fewer flashbacks and less severe clinical symptoms than those who are not. This will inform the potential future development of a simple technique to prevent distressing psychological symptoms after a traumatic event.
The purpose of this study is to compare the 0.018-inch and 0.022-inch bracket slot systems to determine which is more effective for orthodontic treatment .
