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.
Cancer is one of the leading causes of death internationally. When planning treatment for most cancers, it is important to know how far it has spread, including whether or not the cancer has spread to the local lymph nodes (LNs) because this affects the treatment strategy. This is termed "staging", and can be achieved by medical imaging, such as by ultrasound, computed tomography (CT) or magnetic resonance imaging (MRI) scans. However, these are imperfect, and sometimes incorrect treatment decisions are made because of errors in staging by imaging. Improved accuracy would be of great clinical value for almost all solid organ tumours. An emerging technique to address this is photoacoustic tomography (PAT), a non-invasive, safe modality that relies on light and sound to generate images. Laser light is applied to the area to be imaged; this is absorbed, and causes the illuminated tissue to emit ultrasound waves. These can be detected and turned into an image by post-processing techniques similar to those used in conventional diagnostic ultrasound. By changing the wavelength of light used, the technique can be adjusted to optimise detection of various body components, including fat, water and both oxygenated and deoxygenated blood. This means the images can represent tissue composition and function rather than just anatomical structure. Hitherto, most work on PAT has been on healthy volunteers, and has focused on imaging the vasculature. We would like to see whether we are able to generate images of deeper structures inside the body. Initially we will focus on patients with vascular disease, whom we expect to have abnormal blood vessels; and subsequently we will attempt to image tumours and LNs in patients with cancer.
Breast cancer is the most prevalent cancer affecting women. To treat locally advanced breast cancers, neoadjuvant chemotherapy (NACT) is often carried out before surgery to reduce the tumour size to allow breast conservation surgery. However, treatment response for individual patients varies, where the tumour may not respond to treatment and the quality of patient care is compromised if the NACT treatment plan is not optimised. Therefore, the assessment of NACT efficacy is beneficial for the early identification of these patients and appropriate management of treatment. Breast tumours have unique features compared to healthy tissue, including abnormal tissue structure and biochemical composition. With NACT there are specific changes to such tumour features indicating tumour treatment response. The purpose of this study is to establish how the changes to breast tumour features following NACT treatment are seen in non-invasive imaging. This study will look at scans of breast tumours using magnetic resonance imaging (MRI). Changes to tissue structure will be measured by advanced diffusion MRI techniques and changes to tumour related biochemical substances will be measured by advanced magnetic resonance spectroscopy techniques. The investigators aim to assess if these techniques can provide information on the tumour treatment response following subsequent rounds of NACT treatment. In this longitudinal study, 25 patients undergoing NACT will be recruited for four repeated MRI investigations over the course of NACT treatment. Magnetic resonance (MR) measurements of tissue microstructure and biochemical composition will be compared against histological measurements and radiological assessments of treatment response. The study will recruit patients undergoing treatment at the NHS Grampian. This research is funded by Friends of ANCHOR, Tenovus Scotland Grampian and the NHS Grampian Endowment Research Fund.
All UK patients who participated in the TARGIT-A Trial were initially treated for early breast cancer between 2000-2012. A total of 3451 patients from 33 hospitals in 11 countries participated in the trial and a comparison was made between traditional radiotherapy given over several weeks (external beam radiotherapy, EBRT) with TARGeted Intraoperative radioTherapy (TARGIT-IORT) as a single dose given during the operation to remove the breast cancer. The trial was funded by the Health Technology Assessment (HTA) programme of the Department of Health, UK and sponsored by University College London. The results from this trial have been published in major medical journals and have already started changing the way breast cancer in treated around the world; please see www.targit.org.uk for more details. We would like to continue to collect data about the health status of all patients to enable us to learn about longer term differences in the effects of these treatments on health. An analysis of this information could improve treatment for patients with breast cancer. For this, HTA have granted us further funding.
This project is aiming to identify the diagnostic utility CEB (Cardiac Electrical Biomarker) in patients who are undergoing cardiac investigations.
The objective of the rFVIIa for Acute Hemorrhagic Stroke Administered at Earliest Time (FASTEST) Trial is to establish the first treatment for acute spontaneous intracerebral hemorrhage (ICH) within a time window and subgroup of patients that is most likely to benefit. The central hypothesis is that rFVIIa, administered within 120 minutes from stroke onset with an identified subgroup of patients most likely to benefit, will improve outcomes at 180 days as measured by the Modified Rankin Score (mRS) and decrease ongoing bleeding as compared to standard therapy.
Increasing attendances by children (aged 0-16 years) at UK emergency departments (EDs) is putting pressure on the National Health Service (NHS). Health professionals make complex judgements on whether children attending EDs can be sent home safely or require admission. The Pennine Acute Hospitals (PAT) Paediatric Observation Priority Score (PAT-POPS) was developed as an ED-specific screening tool for this purpose. A preliminary study showed it to be a potentially effective tool for deciding admission of children from the ED. Therefore, the focus of this study is to refine the original screening tool.
The purpose of this study is to evaluate the long-term safety and efficacy of pembrolizumab (MK-3475) in participants from previous Merck pembrolizumab-based parent studies who transition into this extension study. This study will consist of three phases: 1) First Course Phase, 2) Survival Follow-up Phase or 3) Second Course Phase. Each participant will transition to this extension study in one of the following three phases, depending on the study phase they were in at the completion of the parent study. Participants who were in the First Course Phase of study treatment with pembrolizumab or lenvatinib in their parent study will enter the First Course Phase of this study and complete up to 35 doses or more every 3 weeks (Q3W) or 17 doses or more every 6 weeks (Q6W) of study treatment with pembrolizumab or a pembrolizumab-based combination or lenvatinib according to arm assignment. Participants who were in the Follow-up Phase in the parent study (post-treatment or Survival Follow-up Phase) will enter the Survival Follow-up Phase of this study. Participants who were in the Second Course Phase in their parent study will enter Second Course Phase of this study and complete up to 17 doses Q3W or 8 doses Q6W of study treatment with pembrolizumab or a pembrolizumab-based combination according to arm assignment. Any participant originating from a parent trial where crossover to pembrolizumab was permitted upon disease progression may be eligible for 35 doses as Q3W or 17 doses Q6W of pembrolizumab (approximately 2 years), if they progress while on the control arm and pembrolizumab is approved for the indication in the country where the potential eligible crossover participant is being evaluated.

Diet has a considerable influence on microbiota composition and the intake of either prebiotics (microbiota-specific food or probiotics (live microbiota species) has been shown to induce positive effects in both anxiety and depression. At present there are few studies exploring stress-related conditions such as emotional/comfort eating behaviours, particularly in individuals who have experienced early life stress and/or find stress difficult to deal with in regards to gut microbiome composition and subsequent behavioural outcomes. Early life stress has been linked to the development of bulimia nervosa and anorexia nervosa in adolescence and adulthood and since the gut microbiota has been proposed as having a causal role in the aetiology and/or maintenance of disordered eating, an empirical question is whether the microbiota may mediate the relation between stress and disordered eating. This is an investigation into the effects of chronic daily consumption of a prebiotic on stress-related eating and mood.
This study is an observational (ie, noninterventional), longitudinal, multicenter, global registry for patients with pyruvate kinase (PK) deficiency, a rare nonspherocytic hemolytic anemia. This Registry will be open for enrollment for 7 years and all enrolled participants will be followed prospectively for a minimum of 2 years, and up to 9 years. Data will be collected from participating Registry Physicians, participants, and, where appropriate, parents/guardians who have provided informed consent or assent (where relevant) and authorization pursuant to applicable laws and regulations. Data should include demographic, clinical, and treatment data; and other data of relevance to the management of patients with PK deficiency. Annual chart review and data entry are expected in order to enhance longitudinal understanding of PK deficiency; however, no specific protocol schedule of assessment is required by this Registry protocol.
