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 study is the first study in the RestorAATion clinical program. The purpose of this first-in human (FIH), double-blind, randomized, placebo-controlled, single ascending dose (SAD) and multiple-dose Phase 1 study is to assess the safety, tolerability, and PK of WVE-006 compared to placebo in healthy participants following a single dose (Period 1) and multiple doses (Period 2) of WVE-006. This information will be used to determine doses and regimes that have the potential to be pharmacologically active in patients with Alpha-1 antitrypsin deficiency in the RestorAATion 2 study, and the maximum safe and tolerable dose that may be given to these patients.
Percutaneous pulmonary valve revalvulation (PPVR) has emerged as an alternative to surgery for the treatment of congenital heart disease with right ejection pathway dysfunction. The Melody valve (Medtronic Inc., Minneapolis, Minnesota) was the first to be used, validated in 2006 by the European Commission and in 2010 by the Food and Drug Administration (FDA). Subsequently, the Sapien valve (Edwards SAPIEN pulmonic transcatheter heart valve, Edwards Lifesciences, Irvine, California) was subsequently approved for PPVR (Europe, 2010; FDA 2016). Infective endocarditis (IE) after PPVR is currently a major concern with an incidence after Melody PPVR estimated at 3%, much higher than the rate of prosthetic left-heart IE. The Sapien valve has been introduced more recently and some cases of IE have been published. Despite the attention this issue is receiving, there are few studies of sufficient size or statistical power to elucidate the risk factors for developing an IE after PPVR according to the type of valve implanted. Recently, a multicenter study was published by the American team of McElhinney et al (J Am Coll Cardiol 2021 ; 78 :575-589). Although it was a sizeable cohort (2476 patients), there was a large disparity in the ratio of patients who underwent revalvulation with either the Melody or Sapien valve, in favor of Melody patients (2038 Melody patients vs. 438 Sapien patients). In this study, the estimated risk of IE was higher for patients who received a Melody valve, according to univariable analysis but not anymore after multivariate analysis. To further answer this question, we develop an international retrospective multicenter registry whose main objective will be to characterize the incidence rate of infective endocarditis after percutaneous pulmonary revalvulation according to the type of valve implanted (Melody vs. Sapien) using a large population of patients with comparable characteristics (match-population).
The purpose of the study is to evaluate the safety, tolerability, pharmacokinetics, and pharmacodynamics of VX-670 at different single and multiple doses in participants with DM1.
Diseases of the heart and circulation are known as cardiovascular diseases, and they cause over 160,000 deaths each year. Coronary heart disease (CHD) is the most common cardiovascular disease. This is due to a build-up of fatty material, known as atherosclerosis, in the blood vessels supplying blood to the heart muscle. This can cause chest pain or if blocked, can cause a heart attack. Two of the main non-invasive tests to look for coronary heart disease are Computed Tomography Coronary Angiography (CTCA) and Stress Echocardiography (Ultrasound scan). CTCA shows the arteries and allows small amounts of disease to be seen that may not yet be causing any symptoms. However, if there's lots of disease and calcification, it becomes difficult to tell how severe it is, which means several tests may be needed. Stress Echocardiography shows if enough blood is reaching the heart muscle, so can show if there is severe disease that needs treatment. However, it can't see the arteries so doesn't showt small disease that may benefit from tablet treatment. There is not yet an effective non-invasive combined test that can give all this information in one go. Studies have shown that if there's atherosclerosis in another artery, a person is very likely to have coronary atherosclerosis as well. Carotid atherosclerosis, in the neck arteries, can be seen with ultrasound similar to stress echocardiography. So, by combining these two tests the investigators want to see if it is possible to see severe as well as small areas of disease in one test, to provide better treatment. The study will enrol 2,000 participants, who need investigation for CHD, equally randomised to CTCA or stress echocardiography with carotid ultrasound. We will follow these participants for 5 years and observe for any adverse outcomes and ask them to complete a questionnaire.
There has been literature demonstrating the effectiveness of correcting these MRI images by using an additional measurement of the magnetic field, but the implied improvement in lesion detection in these common distorted regions in the prostate has yet to be shown. We propose that introducing this distortion correction would greatly improve the DWI images used for tumour detection. For this study we propose testing this hypothesis as a primary objective, and as a secondary objective including additional b-values to further refine the ADC value. The study involves adding one additional distortion correcting scan to the standard clinical study, adding approximately 2 minutes to the study.
The goal of this trial is to compare the effect of using 3D (three-dimensional) versus 2D (two-dimensional) training models when novice medical students practise certain laparoscopic tasks. The main question our trial aims to answer is: -Are the 3D training models used superior compared to the existing 2D LapPass training models for laparoscopic skills learning in novel medical students? Participants will be assigned in one of the 2 groups and practise laparoscopic tasks in 2 separate sessions.
The primary objective of this study is to assess the efficacy of ALXN2220 in the treatment of adult participants with ATTR-CM by evaluating the difference between the ALXN2220 and placebo groups as assessed by the composite endpoint of all-cause mortality (ACM) and total cardiovascular (CV) clinical events.
A sample of 30 alcohol-related liver disease patients will be recruited through consecutive sampling, facilitated through the Alcohol Care Team, which will identify potential participants to the study that have been referred to the team. Patients will be randomised either to the control or intervention group. In the control group, patients will receive outpatient integrated liver care (hepatology, psychosocial and addiction follow-ups). In the intervention group, a contingency management intervention will be delivered in addition to integrated care.
Cancer therapy-related cardiac dysfunction (CTRCD) is when the heart's ability to pump oxygenated blood to the body is compromised. It is a side effect of cancer therapy which can occur as commonly as in 1 in 5 patients. When this occurs, heart failure medications are started to protect the heart from progressing to heart failure. With early detection and treatment, heart function recovers to normal in >80% of patients. Unfortunately, heart failure medications are associated with an undesirable long-term pill burden, financial costs, and side-effects (e.g., dizziness and fatigue). As a result, cancer survivors frequently ask if they can safely stop their heart failure medications once their heart function has returned to normal. Currently there is no scientific evidence in this area of Cardio-Oncology. To address this knowledge gap, the investigators have designed a randomized control trial to assess the safety of stopping heart failure medication in patients with CTRCD and recovered heart function. The investigators will enrol patients who have completed their cancer therapy and are on heart medications for their CTRCD, which has now normalized. The investigators will randomize patients with no other reasons to continue heart failure medications (e.g., kidney disease) to continuing or stopping their heart medications safely. All patients will undergo a cardiac MRI at baseline, 1 and 5 years with safety assessments at 6-8 weeks, 6 and 9 months and 3 and 5 years. The investigators will determine if stopping medications is non-inferior to continuing medications by counting the numbers of patients who develop heart dysfunction by 1 year in each group.
This study aims to investigate the effect of a single dose (300mg) of encapsulated aqueous lemon balm extract on measures of calmness and mood during periods of cognitive demand over the course of the day in healthy adults aged 18-40 years with moderate stress (PSS entry between 14 to 26).
