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.
Atrial fibrillation (AF) is a heart rhythm disorder associated with debillitating symptoms, psychological distress and heart failure. It can also significantly increase an individuals stroke risk. Catheter ablation (CA) for AF is the most effective way to restore normal heart rhythm. However, AF can recur in up to 50% of patients after their first CA procedure and a second 'top-up' procedure may be needed to maximise effect. Early detection of recurrences can enable planning and treatment and repeat CA procedures. Post-CA follow-up strategies rely on episodic rhythm monitoring (Holter monitor tests) that usually last between 1 and 7 days. However, AF recurrences can be intermittent and may not occur during these short monitoring episodes. A greater duration of monitoring has been shown to yield greater detection of AF recurrences. Relying on symptoms alone to detect recurrence is also sub-optimal. AF recurrences can also be insidious. Similar symptoms may be reported from ectopy, atrial tachycardias or atrial flutter. These may require different management approaches, necessitating rhythm characterisation before considering a repeat CA. The Apple Watch (AW) is a wristwatch that is able to monitor a wearer's heart rate and rhythm regularity as well as facilitating an immediate, real-time single-lead ECG recording. This non-invasive device that can be purchased over- the-counter has demonstrated feasibility in detecting AF and may offer a potential non-invasive, alternative long-term rhythm surveillance strategy to diagnose AF in these patients. The investigators propose a single-centre, randomised controlled study to compare the standard follow-up strategy after index AF CA versus one supplemented with an AW-led prolonged monitoring strategy to determine if the latter will improve the expediency and rate of AF recurrence detection. Whether this will lead to improved downstream decision-making, reduction in symptomatic events and a lower prevalence of AF in the longer term will also be studied.
Melanoma (skin cancer) frequently develops from existing moles on the skin. Current practice relies on expert dermatologists being able to successfully identify new/changing moles in individuals with multiple moles. Total body photography (TBP-high-quality images of the entire skin) can track and monitor moles over time to detect melanoma. However, TBP is currently used as a visual guide when diagnosing melanoma, requiring visual inspection of each mole sequentially. This process is challenging, time-consuming and inefficient. Artificial intelligence (AI) is ideally suited to automate this process. Comparing baseline TBP images to newly acquired photographs, AI techniques can be used to accurately identify and highlight changing moles, and potentially distinguish harmless moles from cancerous changes. Astrophysicists face a similar problem when they map the night sky to detect new events, such as exploding stars. Using AI, based on two or more images, astrophysicists detect new events and accurately predict how they will appear subsequently. This project, called MoleGazer, is a collaboration with astrophysicists aiming to apply AI methods that are currently used for astronomical sky surveys, to TBP images. The MoleGazer algorithm, developed at Oxford University Hospitals NHS Foundation Trust, will automatically identify the appearance of new moles and characterise changes in existing ones, when new TBP images are taken. To optimise this MoleGazer algorithm TBP images will be taken at multiple time-points, as there are no existing datasets of TBP images that are publicly available. The investigators invite a) high-risk patients attending skin cancer screening clinics to attend sequential three-monthly TBP imaging and clinical assessment and b) any patient who undergoes TBP as standard care to share images so that the investigators can develop the MoleGazer algorithm. The ultimate goal is for the MoleGazer algorithm to 'map moles' over a patient's lifetime to detect changes, with the eventual aim to detect melanoma as early as possible.
Around one in ten women have high blood pressure in pregnancy. This is potentially serious, with risks to the woman and her baby. Whilst maternal deaths from high blood pressure in pregnancy are now rare in the UK, blood pressure problems in pregnancy still cause many stillbirths and early births. Studies have shown that women of Black and Asian backgrounds are more likely to have worse pregnancy outcomes when blood pressure problems in pregnancy develop. This study aims to: i) describe the burden of disease of high blood pressure in pregnancy amongst babies admitted to neonatal units on a national scale. ii) investigate outcomes for babies born to women with high blood pressure in pregnancy admitted to UK neonatal units across maternal ethnic groups. To complete this study, we will use the National Neonatal Research Database, which holds population-level data for all babies admitted to neonatal units (where unwell babies receive care) in the UK. We will look at records of babies admitted to neonatal units in England and Wales between 2012 and 2020. The records will include information on over half a million babies and their mothers. We will assess how many babies admitted to neonatal units were born to women who had high blood pressure in pregnancy. We will report the outcomes of these babies, and how they compare to babies born to women without high blood pressure in pregnancy. We will analyse whether outcomes for babies born to women with high blood pressure in pregnancy varies according to maternal ethnicity, and investigate what may be driving differences we find.
The primary objective of this study is to evaluate the effect of setanaxib on alkaline phosphatase (ALP) at Week 24 in participants with PBC and with elevated liver stiffness and intolerance or inadequate response to ursodeoxycholic acid (UDCA).
The purpose of the study (Part 1 and Part 2) is to evaluate the safety of a step-up dosing approach (starting with low doses followed by higher doses) of the study medicine (elranatamab) in participants with multiple myeloma that has come back after responding to treatment or has not responded to treatment (relapsed/refractory multiple myeloma). This study will also look at the safety and efficacy of different doses of elranatamab, as well as different intervals between doses. Participants in the study will receive elranatamab as an injection under the skin at the study clinic. After the initial step-up doses, participants will start receiving one dose every week. The frequency of clinic visits for injections may then decrease over time. Participation will be at least two years.
In the UK there are over 7,000 leg amputations each year because of diabetes. The most important cause of this is poor circulation. The detection of poor circulation in patients with diabetes is difficult. A number of tests exist to detect poor circulation (known as peripheral arterial disease (PAD)). However, there is confusion as to which is the gold standard. The DM PAD study aims to determine the diagnostic performance of index tests (audible handheld Doppler, visual handheld Doppler, ankle brachial pressure index (ABPI), exercise ABPI and toe brachial pressure index (TBPI)) for the diagnosis of PAD in patients with diabetes as determined by a reference test (CTA or MRA).
This study is an open-label, multicenter Phase II study of capivasertib administered orally in participants with Relapsed or Refractory (R/R) B-cell Non-Hodgkin's Lymphoma (NHL).
The geko™ Cross Therapy REGISTRY - Wound is a prospective, observational, anonymised data collection Registry with no experimental treatment that will fulfil an unmet need for an observational Registry to provide long-term clinical data to demonstrate patient benefit and regulatory compliance.
This study will test the COVID-19 vaccine candidate AZD1222 to investigate its safety, tolerability and capability of boosting immune responses both in the blood and the lung when administered to the respiratory tract, in volunteers previously vaccinated by intramuscular COVID-19 vaccination. Using standardised methods, we will measure immune responses in the blood, nose and lower airway and compare with data from ongoing clinical trials of intramuscular vaccination. Thus, we will show the effect of the delivery method and provide the critical information required to begin further clinical trials to show the efficacy of this needle-free vaccination strategy for booster vaccination.
This is a Phase 1, randomized, double-blinded, placebo controlled study. The study consists of 4 parts: Part 1 is a single ascending dose (SAD) study in healthy volunteers; Part 2 is a multiple ascending dose (MAD) study in subjects with stable, mild asthma; Part 3 is a repeat dose in patients with moderate to severe asthma and Part 4 is a repeat dose in patients with COPD.
