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.
Migraine is a very common condition characterised by frequent severe headaches that are very debilitating. Although the frequency and severity does reduce as patient's age, particularly above the age of 70, in younger and working age people this condition has a significant impact on people's lives. Patients with migraine are typically diagnosed and managed in primary care, but can also be treated by neurologists. Recently, NHS England has published guidance for clinical staff to optimise patient management: reduce admissions to hospital for migraine and improve the setting in which patients are seen. One recommendation is the increased use of headache diaries by patients. These may help patients and doctors to improve migraine diagnosis and its treatment, for example by identifying if there are triggers for getting a migraine attack. With technological advancements, there are now computer/phone applications (Apps) that can be used instead of a paper diary. The Curelator N1 Headache App is one of such migraine specific Apps. In this study, the investigators aim to evaluate if primary care migraine patients are open to using a digital headache diary App, and how compliant users of the App will be. The investigators also aim to assess patient feedback on the use of the N1 Headache App, and if its use aids them in the management of their migraine.
The dexamethasone 700 μg intravitreal implant (DEX-I) delivers dexamethasone gradually to the retina over time. It is an approved drug for the treatment of DME. This study will assess adult participants with diabetic macular edema (DME) and suboptimal response to anti-vascular endothelial growth factor therapy that are treated with DEX-I in the routine clinical setting. Approximately 327 participants who are prescribed DEX-I by their physicians will be enrolled at approximately 40 sites in approximately 10 countries globally. Participants will be followed for 18 months post-DEX-I implantation according to the routine clinical practice of the prescribing centers. Only one eye per participant will be evaluated in the study. No additional burden for participants in this trial is expected.
Malaria is a major public health problem. There were around 240 million cases of malaria and 627,000 deaths worldwide in 2020. There is a great need for a safe, effective malaria vaccine and the team at University of Oxford is trying to make vaccine(s) which can prevent serious illness and death. This study is being done to assess an experimental malaria vaccine for its ability to prevent malaria illness. This is done using a 'blood-stage challenge model'. This is when volunteers are infected with malaria parasites using malaria-infected red blood cells. The vaccine we are testing in this part of the study is called "RH5.2-VLP". It is given with an adjuvant called "Matrix-M". This is a substance to improve the body's response to a vaccination. RH5.2-VLP is being tested for the first time in humans in this trial. The Matrix-M adjuvant has been given to tens of thousands of people, with no major concerns, such as illness. The aim is to use this vaccine and adjuvant to help the body make an immune response against parts of the malaria parasite. This study will assess: 1. The safety of the vaccine in healthy participants. 2. The response of the human immune system to the vaccine. 3. The ability of the vaccine to prevent malaria illness (Group 2 only). We will do this by giving healthy adult participants (aged 18-45) three of the vaccines and/or expose participants to malaria infection at the Centre for Clinical Vaccinology and Tropical Medicine (CCVTM), Churchill Hospital in Oxford. We will then do blood tests and collect information about any symptoms that occur after vaccination. There will be 19 to 54 visits, lasting between 3 months to 2 years and 2 months.
This is a multicentre prospective cohort study, primarily aimed at reporting the frequency and intensity of radiotherapy side-effects of patients with soft tissues sarcoma of the extremities (STSE). Two sub-studies are proposed within this study: - MRI radiation response assessment Aimed at establishing whether changes in median apparent diffusion coefficients (ADC) are predictive of pre-operative STSE response measured using histopathology. - Biomarker development and Immune mediators associated with radiotherapy Aimed at establishing prognostic markers which may refine selection of cases for pre-operative, palliative or no radiotherapy. Also, aimed at determining if radiotherapy stimulates the tumour microenvironment, resulting in measurable change in anti-tumour immunity and if certain subtypes could potentially benefit from the addition of immunotherapy with radiation. Patients participation in the sub-studies is optional.
This study aims to establish the metabolic/molecular response in both adipose tissue and skeletal muscle as well as sensory experiences (pain, fatigue, drive) to prolonged fasting of 3 days duration. Participants will undergo sequential meal assessment before and after a 3 day fast with measures taken throughout each fasting day.
Respiratory disease affects one in five people and is a leading cause of global morbidity and mortality. Chronic obstructive airways diseases encompass conditions characterised by expiratory airflow limitation, exertional dyspnoea, activity limitation and impaired quality of life. The most common conditions include chronic obstructive pulmonary disease (COPD), asthma, bronchiectasis, cystic fibrosis and primary ciliary dyskinesia. In recent years, there has been concerted effort in the scientific and respiratory medicine community to improve the diagnosis and management of chronic obstructive airways diseases using personalised or precision medicine (i.e., tailoring therapies and interventions according to specific "treatable traits") and identifying phenotypes or endotypes using validated biomarkers. To date, however, research in this setting has primarily focussed on people with COPD and asthma, with limited studies in other forms of chronic obstructive airways diseases. The aim of this study is therefore two-fold; first, to compare pulmonary physiology (i.e., large and small airway involvement) and extra-pulmonary manifestations across the spectrum of chronic obstructive airways, and second, to determine how disease-specific treatable traits associate with physical activity and health-related quality of life.
Eating too much salt raises blood pressure and the risk of having a heart attack or stroke. The investigators do not fully understand why salt raises blood pressure, but storage of sodium in the body, particularly in the skin, may be important. For this reason, the investigators wish to study the link between skin sodium, blood pressure and cardiovascular risk in patients with high blood pressure, of different ethnicities, using techniques such as skin biopsy and magnetic resonance imaging (MRI). The results will provide detailed information on skin sodium storage and help us better understand the effects of blood pressure medications on these mechanisms. Ultimately, the investigators aim to develop personalized treatment guidelines for clinical use.
This is a retrospective non-interventional study to describe the HCRU and clinical outcomes before and after AspireSR® device implantation in subjects with drug resistant epilepsy at the Queen Elizabeth Hospital, Birmingham (QEHB).
Study KER-012-A201 is Phase 2, double-blind, randomized, placebo-controlled study to determine the efficacy and safety of KER-012 compared to Placebo in adults with PAH (WHO Group 1 PH) on stable background PAH therapy. The study is divided into the Screening Period, Treatment Period, Extension Period, and Follow-Up Period.
The goal of this clinical trail is to compare the differences in carotid plaque Treg cells' gene signature for activation, proliferation, and suppressive function using scRNA-seq in patients treated with IL-2 compared to control.
