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 accurately describe the rehabilitation needs of individuals with post-COVID-19 syndrome up to 36 months after infection, allowing better diagnosis, triage and resource management. A major focus will be the impact on everyday life to return to normal activities.
To compare the efficacy and safety of remibrutinib versus teriflunomide in patients with relapsing multiple sclerosis (RMS)
Multicenter, open-label, randomized, controlled phase III clinical trial to evaluate and compare the activity and safety of two experimental arms consisting of lurbinectedin as single agent (Group A) or the combination of lurbinectedin with irinotecan (Group B) versus Investigator's Choice (topotecan or irinotecan) as control arm (Group C), in Small-cell Lung Cancer (SCLC) patients who failed one prior platinum-containing line.
This non-randomised, prospective trial will examine the feasibility and efficacy of VT ablation guided by activation mapping using the Octaray and Optrell catheters. Annotation algorithms within the CARTO3 electro-anatomical mapping system will be integrated with 3D scar segmentation data from cardiac MRI (ADAS-VT), and extrastimulus voltage mapping will identify sites of interest for focussed activation mapping. The investigators hypothesise that the examination of these data will identify critical target sites for ablation. Intra-procedural diagnostic performance of the Octaray and Optrell catheters will be assessed as the primary outcome, and will be compared with the standard of care. Secondary, clinical outcomes - primarily the need for ICD therapies at 12 months post ablation - will be compared with propensity-matched controls undergoing substrate-based ablation alone. Follow-up MRI scans will review the impact of ablation on the elimination of conduction channels.
This study is being done to find out if zanidatamab, when given with chemotherapy plus or minus tislelizumab, is safe and works better than trastuzumab given with chemotherapy. The patients in this study will have advanced human epidermal growth factor 2 (HER2)-positive stomach and esophageal cancers that are no longer treatable with surgery (unresectable) or chemoradiation, and/or have grown or spread to other parts of the body (metastatic).
Stroke occurs when a blood clot causes a blockage in a blood vessel (artery) within the brain. This type of stroke is called an ischemic stroke and carries a high risk of disability or death. Stroke must be treated very fast. Any delay of even 10 minutes can result in the difference between an independent and a disabled outcome, and in some cases between life and death. Endovascular therapy (EVT) or Thrombectomy is a procedure to remove the blood clot (thrombus) from a blood vessel to reopen it (recanalization). Patients are likely to benefit from a thrombectomy procedure when it is performed in a larger blood vessel. Currently it is not known if thrombectomy procedure will benefit the patients presenting with the stroke that has been caused by a blood clot in a medium sized blood vessel (medium vessel occlusion, MeVO). This trial will enrol patients diagnosed with acute stroke due to a clot in the medium sized vessel. The patients will be randomized within 12 hours of their symptom onset to either standard of care or standard of care plus thrombectomy procedure. The participation will last for 12 months Escape MeVO coordinating centre is located at the University of Calgary. There will be up to 75 sites. We will be recruiting a total of 530 patients.
Malaria is a major public health problem in Africa. An important way to control the disease is by Indoor Residual Spraying of insecticide in houses. Insecticide resistance has become a major problem. This trial will evaluate a novel insecticide against those insecticide resistant mosquito vectors in Tanzania E Africa.
Loneliness is a significant problem for young people and is associated with a range of physical and mental health difficulties. Meta-analyses have identified that interventions aimed at young people who report loneliness as their primary problem are lacking within the literature. In adults, the most effective interventions for loneliness are those which target the underlying maladaptive social cognitions. Therefore, the investigators have developed a modular Cognitive Behavioural Therapy (CBT) intervention for children and young people aiming to reduce their feelings of loneliness. The aim of this study is to conduct a multiple baseline single-case experimental design (SCED) to assess the efficacy, feasibility and acceptability of this intervention. In total 6-8 11-18-year-olds and their families will be recruited. The design consists of AB+ post-intervention, where A is the baseline phase, B is the intervention phase and then a post-intervention phase. Participants will complete a baseline assessment, before being randomised to one of four different baseline lengths (12 days, 19 days, 26 days or 33 days). Participants will then complete an average of 12 sessions of CBT, with the aim being to reduce their feelings of loneliness over 12 weeks. Participants will then complete a 12-day post-intervention phase. Participant loneliness will be repeatedly assessed throughout the three phases of the intervention using the Three-item Loneliness Scale, which will be the primary outcome. Secondary outcomes will be reliable and clinically meaningful change on the UCLA-LS-3, RCADS and SDQ. Feasibility and participant satisfaction will also be assessed and reported.
Every day, doctors and nurses make hundreds of decisions about treatments - like when to start or stop them, or how frequently to give them. Ideally, decisions are based on gold standard evidence from Randomised Controlled Trials (RCTs). Unfortunately, for many treatments little or no evidence exists and clinicians must use knowledge and experience to decide what is best. As clinicians are all different, this leads to random variation in how treatments are given to patients. For example, magnesium is routinely given in intensive care to prevent abnormal heart rhythms. There is little evidence supporting this, and clinicians vary in how they administer magnesium. Traditional RCTs might be used to examine whether more magnesium is better than less magnesium, but this method is inefficient and expensive for investigating multiple comparative treatment questions. Clinical trials are becoming more efficient by using existing hospital computer systems to run them. However, research teams continue to perform tasks like randomisation manually. For questions like magnesium supplementation, which occur daily, this is labour intensive and infeasible. Hospital computer systems also possess mechanisms for prompting and alerting clinicians for particular decisions, reminding them of best practices, warning them of potential problems. These systems may be modified to allow clinicians to randomise patients, under specific conditions. The investigators propose to assess whether modified computer prompts can be used to highlight the magnesium supplementation decision to clinicians. These would prompt the clinician to evaluate the uncertainty around giving or withholding magnesium in that instance. If in agreement that the optimal decision is unclear, clinicians can choose to randomise the patient within a predetermined trial structure. If the clinician knows better, they may override the prompt and continue with their preference. In both cases, the system learns from the decision and the patient receives optimal care determined by their clinician.
