NCT ID: NCT04549805 Completed - Clinical trials for Coronary Artery Disease

Troponin to Risk Stratify Patients for Computed Tomography Coronary Angiography

PRECISE-CTCA
Start date: December 4, 2018
Phase:
Study type: Observational

Most patients presenting to hospital with chest pain are discharged home without further tests once a heart attack has been ruled out. Current strategies to assess patients with a suspected heart attack involve blood tests to measure troponin, a protein released into the bloodstream when the heart muscle is damaged. Despite having had a heart attack ruled-out, some patients have unrecognised coronary heart disease and are at risk of having a heart attack in the future. However, we do not know what is the best approach to identify and treat these patients. This study will use a heart scan known as computed tomography coronary angiogram (CTCA) to look for underlying coronary heart disease in patients who have had a heart attack ruled out. In an earlier study, we performed this scan in patients referred to the outpatient cardiology clinic with stable chest pain and found that this improved the diagnosis of coronary heart disease, leading to improvement in patient care that prevented many future heart attacks. Our research has also demonstrated that troponin levels below the threshold used to diagnose a heart attack identify those who are at greater risk of having a heart attack in the future. The aim of this study is to confirm whether these low levels of troponin can identify patients who have underlying coronary heart disease and may benefit from further testing and preventative treatment.

NCT ID: NCT04546854 Completed - Influenza Vaccine Clinical Trials

Influenza 2020/2021

Start date: September 21, 2020
Phase: N/A
Study type: Interventional

As part of the fight against COVID-19, the UK government has announced its most comprehensive flu campaign to date (https://www.gov.uk/government/news/most-comprehensive-flu-programme-in-uk-history-will-be-ro lled-out-this-winter). This should not be surpising: every year NHS hospitals experience an overwhelming number of influenza cases, and COVID-19 increases this concern. As in previous years, the flu vaccine is free at the point of care for people 65 and over. New this year is that later in the season the vaccine will be made available free at the point of care for people 50 and over. However, if people refuse to take the vaccine this comprehensive program cannot benefit public health. The degree to which vaccine hesitancy is expressed varies across characteristics of the vaccine considered and the time and place it is offered, and across characteristics of the person's perceptions of complacency, convenience, confidence, calculations, and communal responsibility, i.e. the "5Cs". Information campaigns can be used to influence all 5Cs, and public facing information is often a necessary component of public health campaigns that may also include structural components. Largely, information campaigns can be viewed as a type of educational intervention. Educational interventions may fall short of what is needed to alter people's intentions to vaccinate where they focus on system 1 rational thinking processes and neglect system 2 automatic thinking processes. To be more effective, public health messages must be tailored to align with the "beliefs, attitudes, and motivations" of the very people they intend to influence. Fact-led educational interventions to increase parents' intentions to vaccinate their children are particularly ineffective where more subtle content opposes the recipient's deep-seated values. In a different context, recycling behaviour, previous research demonstrated that messages aligned with people's deep-seated values (i.e. the moral foundations that underlie political ideologies) are more likely to promote desired behavioural intentions than unaligned messages. The present research expands the scope of previous research in two ways. First, rather than investigating parental attitudes towards vaccination, the investigators will look at people's intentions to self-vaccinate. Second, the investigators will explore the effectiveness of messages aligned with the moral foundations that underlie individual's political ideologies on their intentions to be vaccinated.

NCT ID: NCT04546581 Completed - COVID-19 Clinical Trials

Inpatient Treatment of COVID-19 With Anti-Coronavirus Immunoglobulin (ITAC)

Start date: October 8, 2020
Phase: Phase 3
Study type: Interventional

This protocol will serve as a platform for assessing treatments for adult patients hospitalized for medical management of COVID-19 without related serious end-organ failure. Trials will involve sites around the world strategically chosen to ensure rapid enrollment. This trial will compare hyperimmune intravenous immunoglobulin (hIVIG) with matched placebo, when added to standard of care (SOC), for preventing further disease progression and mortality related to COVID-19. SOC will include remdesivir unless it is contraindicated for an individual patient.

NCT ID: NCT04546347 Completed - Healthy Volunteers Clinical Trials

A Study to Assess the Rel Bioavailability, Food Effect and Absolute Bioavailability on the Pharmacokinetics of AZD9833

Start date: September 17, 2020
Phase: Phase 1
Study type: Interventional

AstraZeneca AB is developing the test medicine, AZD9833, for the potential treatment of oestrogen receptor (ER) positive breast cancer. ER-positive breast cancer is where the cancer cells grow in response to the hormone oestrogen. The study will try to identify and compare how much of the test medicine formulations (recipes) are taken up into the blood when given as a tablet, a solution and as an injection directly into the vein. The dose given directly into the vein will be radiolabelled, meaning that it contains a radioactive component in order to track where the drug is in the body. This study will also look at the effect of food when taking the test medicine in the form of the tablet. The test medicine safety and tolerability will also be assessed. This is a one-part study involving up to 32 healthy post-menopausal female volunteers aged 50 to 70. Volunteers will be randomly assigned to a group of up to 8, two groups will partake in four study periods and two groups will partake in three study periods. Volunteers will be admitted to the clinical unit on the day before dosing (Day -1) for each study period. On Day 1 of each study period, volunteers will receive either a single oral dose (tablet or solution) of AZD9833 or a single oral dose (tablet) of AZD9833 co-administered with a single radiolabelled IV dose of [14C]AZD9833, in either the fed or fasted state. There will be a minimum 7 day washout between periods. Volunteers will remain resident until 72 hours post dose (Day 4) of each study period. A follow-up phone call will take place 5 to 7 days post-final dose to ensure the ongoing wellbeing of the volunteers.

NCT ID: NCT04544956 Completed - Hepatitis B Clinical Trials

A Mechanistic Study of GSK3228836 With Fine Needle Aspiration (FNA) in Participants With Chronic Hepatitis B

B-Fine
Start date: October 6, 2020
Phase: Phase 2
Study type: Interventional

Hepatitis B virus (HBV) infection, especially chronic, is a significant worldwide medical problem. This is an exploratory study of the therapeutic mechanism of GSK3228836 in participants with chronic hepatitis B (CHB) on stable nucleos(t)ide therapy (which is the first line therapy for CHB). This study is a Phase IIa, multi-center open label exploratory study of the therapeutic mechanism of GSK3228836 in participants with hepatitis B virus e-antigen (HBeAg)-negative CHB on stable nucleos(t)ide therapy using repeat fine needle aspirations of the liver for intrahepatic immunophenotyping. It will investigate the virologic and immunologic correlates of hepatitis B virus surface antigen (HBsAg) loss observed in participants when treated for 12 weeks with 300 milligrams (mg) GSK3228836. Repeat fine needle aspirates of the liver will be performed to enable analysis of liver-resident immune cells to investigate any immunomodulatory properties of GSK3228836 and to study the biology of underlying treatment-associated liver flares. The study will consist of a screening, treatment, and post-treatment follow-up phase. Approximately 20 participants will be enrolled in the study.

NCT ID: NCT04544176 Completed - Covid19 Clinical Trials

COVID-19 Risk From Attending Outpatient Radiology Appointments

Start date: January 1, 2020
Phase:
Study type: Observational

By using recent data on hospital attendance and COVID-19 laboratory tests, available within two NHS trusts in Nottingham and Cardiff we will enable the calculation of the risk of developing COVID-19 infection after attending an outpatient hospital appointment. This will assist in the restart planning when resuming face to face outpatient radiology appointment.

NCT ID: NCT04544020 Completed - Alcoholic Hepatitis Clinical Trials

Changes in gUt micRobiota After Enteral Feeding (in Alcoholic Hepatitis)

CREED
Start date: September 1, 2019
Phase:
Study type: Observational

Drinking large amount of alcohol can cause damage to the liver. If the liver is severely injured by alcohol it can become very inflamed and this condition is called alcoholic hepatitis. Alcoholic hepatitis can be life threatening. There is no cure for alcoholic hepatitis. It is known that stop drinking and have good nutrition can help the liver to recover. Infections are very common for people who suffer from alcoholic hepatitis. Sometimes these infection can be very severe. It is not always possible to find out where the infection is coming from. But the bacteria living in the bowel may move to other organs causing these infections and an illness like alcoholic hepatitis can cause "bad bacteria" to take over from "good bacteria" in the gut. This study wants to understand the changes in the bacteria in the bowel of people who have an acute inflammation of the liver cause by alcohol (alcoholic hepatitis). The investigators will take stool samples from patients admitted in the hospital with alcoholic hepatitis. The investigators will run tests on the stools that can find out which bacteria live in the bowel. Its is expected to find these bacteria to be different from the ones living in the bowel of healthy people. The investigators are interested to see if these bacteria change once the patients are given good nutrition using a small tube from the nose to the stomach. This type of nutrition is used routinely to help improve the liver in severe alcoholic hepatitis. The investigators will take some more stool sample from these patients after the nutrition through the tube has started to check how the bacteria change with nutrition. Better tools to check the bacteria in the bowel are now available so this can help the investigators to understand better if changing bacteria in the bowel can help recovery in alcoholic hepatitis.
