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 population-based study will identify patients with rapid and irregular heartbeat which is not due to a fault with the heart valves (non-valvular atrial fibrillation) who initiate rivaroxaban, apixaban or warfarin as treatment for Stroke Prevention in Atrial Fibrillation (SPAF). Purpose of the study is to learn more about the safety and how well the drugs rivaroxaban, apixaban and warfarin work in patients appropriately and inappropriately receiving standard and reduced doses of each drug for reducing the risk of stroke in atrial fibrillation. Real world data from routine general practice stored in the primary care database in the UK, The Health Improvement Network (THIN), will be used for investigation.
The COLOR trial is a Multicenter Randomized trial. Patients are eligible for study participation when PCI is indicated for complex coronary lesions. If patients comply with inclusion and exclusion and provide written informed consent they will be randomized in a 1:1 fashion between the two study treatments, (7 Fr. radial access with a Glideslender sheath or 7 Fr. femoral access with a standard femoral sheath) , in a 1:1 ratio.
This is a single arm study to evaluate the efficacy, safety and tolerability of zanubrutinib (BGB-3111) in participants with relapsed/refractory marginal zone lymphoma (R/R MZL).
The study will recruit frequent users of cannabis (defined at least fortnightly use) and randomize them either to: (1) form implementation intentions by linking situations in which they are tempted to use cannabis with strategies to avoid using cannabis in those situations by using a volitional help sheet, or (2) to consider the situations in which they are tempted to use cannabis alongside possible strategies to avoid using it as presented in the volitional help sheet but not to form implementation intentions. The effects on self-reported cannabis use will be assessed 1 month post-intervention. Predictors of cannabis reduction will also be examined.
Assessment of PF-06700841 in participants with moderate to severe active, generalized Systemic Lupus Erythematosus (SLE) that have inadequate response to standard of care.
The purpose of this Registry is to assess the procedural success and clinical outcomes associated with various operator techniques for mechanical thrombectomy in large vessel occlusions (LVO).
Factors affecting the pulpal prognosis of injured teeth. Dental injuries may affect the survival of teeth. It is recommended to monitor the injured teeth at regular intervals to ensure that the appropriate treatment is delivered promptly. In order to conclude what treatment is required, a correct diagnosis must be reached. However, reaching this diagnosis can be difficult as injured teeth often respond erroneously to many of the diagnostic tests used, thereby affecting our ability to interpret the results. This study aims to identify the clinical factors that affect the ability of the blood supply of a tooth to survive an injury. This will help ensure that patients are provided with the appropriate treatment with the avoidance of delays that may affect the long-term survival of the tooth. Patients that attend the Edinburgh Dental Institute trauma clinic will be invited to participate in this study. The patients, seen on this clinic, are assessed in regular intervals in a systematic way, as per accepted and validated international guidelines on the subject of dental trauma. There are specific investigations and clinical assessments that are carried out on the initial and each review appointment. The study will attempt to identify those teeth that lose their vitality at different points following the injury and will attempt to link this to the nature of the injury suffered. The data will be collected from the patients' routine dental trauma assessment and no additional investigations will be required. As per routine practice the patients are reviewed for one year following their injury unless otherwise indicated. All responses to the investigations will be collected and combined to identify the prognostic factors associated with the loss of vitality of traumatised teeth.
Tolerance and Acceptability of new oral nutritional supplement - STOCKHOLM.
RESCUE-RACER is jointly sponsored by the University of Cambridge and Cambridge University Hospitals NHS Foundation Trust. The RESCUE-RACER programme evaluates motorsports competitors at baseline (CArBON) and post-injury (CARS). The CArBON study (Competitor Assessment at Baseline; Ocular, Neuroscientific) collects a battery of neuroscientific data in a baseline assessment. The CARS study (Concussion Assessment and Return to motorSport), repeats the CArBON battery throughout the recovery period in competitors who sustain a potentially concussive event during motorsport. The primary outcome of the RESCUE-RACER programme is to establish the natural history of concussive symptoms and signs in motorsport competitors using a comprehensive neuroscientific battery. The standard clinical assessment of concussive symptoms will be correlated with objective clinical scoring, in addition to neurocognitive and neuropsychological assessments. Advanced brain imaging with MRI will be used to further characterize head injuries in motorsport. Finally, salivary biomarkers will be collected to monitor the measurable biological effects of a potentially concussive event immediately following injury and through recuperation in the recovery period. The secondary outcome is investigation of a novel diagnostic tool for concussion, in the form of a 3D head-mounted display and eye tracking system capable of assessing ocular, vestibular and reaction time (OVRT) functions (the I-PAS device, now re-named Dx 100). The results of RESCUE-RACER will form an evidence base for medical decision-making track side after a potentially-concussive incident and will advise on clinic management of motorsports concussion, including the important 'return-to-race' decision.
The purpose of this research is the evaluation of a combined coaxial optical coherence tomography (OCT) system to image retina/choroid and to evaluate if post processing of the data can give us insights into property of the tissue imaged.
