Filter by:During the COVID-19 pandemic, testing primarily relied on the use of nasopharyngeal swabs to detect the SARS-CoV-2 virus, responsible for the disease. However, this technique has several limitations, including the variable quality of swabs, its invasive nature, and arbitrariness in the choice of the number of cycles. Furthermore, it does not allow for the detection of viral proteins. To overcome these limitations, researchers developed the eBAM-CoV test, patented for the detection of viral proteins in the exhaled air of COVID-19 patients. This portable device provides an immediate assessment of the "viral load" with both quantitative and qualitative results, showing promise for early virus detection. The researchers hypothesize that the eBAM-CoV test is likely to exhibit a satisfactory concordance with the reference RT-PCR test in the detection of COVID-19, especially among symptomatic patients or closed contacts.
Eligible participants were randomly assigned (1:1:1), using block randomization stratified, to either 3 groups. Group 1 will be immunized inactivated SARS-CoV-2 vaccine and varicella vaccine in day 0 followed by measles-mumps-rubella vaccine(MMR) in day 28. Group 2 will be immunized varicella vaccine in day 0 followed by SARS-CoV-2 vaccine and MMR in day 28. Group 3 will be immunized inactivated SARS-CoV-2 vaccine in day 0 followed by MMR and varicella vaccine in day 28. Vaccines were administered 28 days apart, with blood samples taken on day 0 and day 28 before vaccination, and on day 56. Local and systemic symptoms and serious adverse events following immunzation were collected.
This study is a phase Ⅱ clinical trial to evaluate the safety and immunogenicity of SCTV01E-2 in people of different ages who had been vaccinated with COVID-19 vaccines. A total of at least 600 subjects aged 3 years and older who were previously vaccinated with domestically licensed SARS-CoV-2 vaccines with recommended doses and immunization schedules are planned to be enrolled. Group A included 400 patients aged 18 years and above, and group B included 200 patients aged 3-17 years.
Following an infection with Severe Acute Respiratory Syndrome coronavirus 2 (SARS-CoV2), one in ten people will experience persisting symptoms, or develop symptoms which can last for months and even years. These symptoms affect people in different ways and have been demonstrated to broadly impact physical, mental, and cognitive health. This is called Long COVID. Currently, there are no treatments available to address the issues that patients experience but anti-viral medications have been suggested as being potentially effective. This study will recruit patients that have confirmed long COVID and participants will undertake a series of tests to determine their symptoms and the impact that their condition has had on their bodily systems. The total duration of each participant's involvement is approximately 8 weeks, and this will involve 13 visits (15 visits if taking part in Exeter) at the closest study location (Derby or Exeter). Initial assessments are conducted over three separate visits and then all participants will be scheduled to receive five consecutive days of a medication that has been identified as having the potential to reduce the impact of Long COVID. Following a period of 28 days, participants will be invited to repeat the same tests that were conducted before receiving the medication so that it can be determined how well the drug has worked. In this study we are specifically collecting information to understand how feasible this medication could be to help patients improve their condition and this will help us to determine how likely this drug is able to be used within the wider Long COVID community. The medication that will be used within this study is an existing anti-viral medication (Remdesivir). If we find patients are able to tolerate the treatment and the research tasks we will use this information to conduct a larger trial to determine how well this drug can be used to reduce the impact of Long COVID in a greater number of patients.
The study aims to investigate the safety and immunogenicity of one dose vs two doses of a T-cell priming next-generation vaccine against Coronavirus disease.
The pandemic caused by SARS-CoV-2 infection has resulted, in addition to the well-known acute symptoms, in the emergence of a plethora of persistent, diffuse and heterogeneous symptoms such as fatigue, shortness of breath and cognitive dysfunction among others, that have come to be called persistent COVID. Patients have reported that physical activity, stress and sleep disturbances often trigger exacerbations of their symptoms related by some authors to the so-called Post Exertional Malaise (PEM) characteristic of Myalgic Encephalomyelitis. Similarly, by analogy with other pathologies, it has been hypothesized that optimal exercise prescription would benefit these people with persistent COVID-19 symptoms but in practice, the rehabilitation of these patients runs the risk of collapsing respiratory and physical rehabilitation services. This is why COPERIA proposes the construction of a platform for respiratory, cardiac and muscular telerehabilitation, to compare with face-to-face rehabilitation treatment and to try to predict the influence of physical activity in the prediction of PEM.
The aim of the study is to characterize and to quantify SARS-CoV-2 strains in stools, in comparison with the viral strains in respiratory samples, from patients hospitalized for COVID-19. The methods will be standard ddPCR quantifying SARS-CoV-2 RNA and next generation sequencing-whole genome sequencing. The expected results will allow us to better understand SARS-CoV-2 dynamics and compartmentalization, both in the respiratory tract and in digestive-related tissues, according to the evolution of SARS-CoV-2 variants.
The purpose of this clinical trial is to Evaluate the Safety and Immunogenicity of PTX-COVID19-B Administered as Booster Vaccination in Previously Vaccinated Adults Aged 18 Years and Older. This study is seeking participants who are: Adult males and females 18 years of age or older; In efficacy cohort : Subjects who were previously vaccinated with 2 doses of Comirnaty® administered at least 3 months prior to the booster dose.. All participants in this efficacy cohort will receive 1 of the 2 study vaccines: PTX-COVID19-B or Comirnaty®. All participants in efficacy cohort will receive a single 40 microgram dose PTX-COVID19-B of the study vaccine or one dose of Comirnaty® at the first study clinic and will return to the study clinic 6 more times. At each clinic visit, a blood sample will be taken. They study is about 6 months long for each participant. In safety cohort: Subjects who have previously received any primary series approved by WHO Emergency Use Authorization at least 3 months prior to enrollment or subjects who have already received one authorized booster vaccination and planned to receive PTX-COVID19-B as the 4th shot will be enrolled. All participants in this safety cohort will receive 1 dose vaccines: PTX-COVID19-B. All participants in safety cohort will receive a single 40 microgram dose of the study vaccine at the first study clinic and will return to the study clinic 5 more times. At each clinic visit, a blood sample will be taken. They study is about 6 months long for each participant.
This is a Phase III, Randomized, Observer-Blind Study to Evaluate the Safety and Superiority in Immunogenicity of PTX-COVID19-B Administered as Booster Vaccination Compared to Vaxzevria® in Adults Aged 18 Years and Older Who Were Previously Vaccinated with Vaxzevria®. This study will be a competitive enrollment process in all participating countries. Once the target number of subjects is reached, the enrollment in all participating countries in the particular phase will be stopped.
The study is a randomized, double-blind Phase II study. It will evaluate the immunogenicity and safety of SCTV01E-1. Approximately 400 participants aged 18 years and older will be enrolled in this study. 160 participants who have not been vaccinated with any COVID-19 vaccine will be enrolled in Cohort 1 and randomly assigned to receive SCTV01E-1 or SCTV01E in a ratio of 1:1. 240 participants who were fully vaccinated with 2 or 3 doses of inactivated COVID-19 vaccines at least three months ago will be enrolled in Cohort 2 and randomly assigned to receive SCTV01E-1 or SCTV01E in a ratio of 1:1.
