Filter by:This study is a multi-centre, blinded, randomized controlled trial. LTCF residents ≥ 65 years who have received three doses of mRNA vaccine will be randomized to vaccination with a fourth dose of Pfizer-BioNtech mRNA- COVID-19 vaccine or to vaccination with a control (Prevnar-13 vaccine).
The main aim of the study is to estimate the potential efficacy of i.v. canrenone as add-on therapy on maximal medical treatment versus maximal medical treatment alone in treating moderate-to-severe ARDS due to SARS-CoV-2.
The aim of the joint project PROVID is to contribute to better outcome prediction for COVID-19 patients, to better clinical management, and to the development of new therapies. To this end, the investigators will collect detailed data on the course of COVID-19 patients and deeply characterize them at the molecular level. The investigators also aim to identify compounds with the potential to improve outcome. The PROVID-PROGRESS study is being carried out as a prospective, longitudinal, multicenter observational study (case cohort study) with material asservation for genomic, transcriptomic and proteomic analyzes on adult patients with COVID-19.
Background: Some people have allergic reactions to COVID-19 mRNA vaccines. Researchers want to learn more about these reactions to provide guidance on who can safely receive the vaccines, including a second dose in people who had a reaction to the first. Objective: To study the safety of giving a second mRNA COVID-19 vaccine dose to people who had a systemic allergic reaction to their first dose. Eligibility: People aged 16-69 who had a systemic allergic reaction to their first dose of COVID-19 vaccine. Design: Individuals who have underlying health issues may need to come to the NIH for screening tests to make sure they are safe to receive the vaccine. People who are eligible to participate in the study will be admitted to the NIH hospital and stay for at least 4 days. They will give urine samples. They will have a nasal swab SARS-CoV-2 test. They will have an intravenous line placed in each arm. They will get the study vaccine (Pfizer-BioNTech COVID-19 vaccine) and one dose of placebo on different days. They will have breathing tests. They may have clinical photography if they develop a rash. Participants will have 4 follow-up visits - 2 by phone and 2 in-person visits at the NIH campus . They will have allergy skin testing at one visit. Drops of different allergens or controls will be placed on their back or arm. The skin under each drop will be scratched with a tool. If the results are negative, a small amount of allergen will be injected just below the surface of their skin. Participants who have no or only a mild allergic reaction to the second dose of the vaccine may be eligible to receive a Booster dose at the NIH. Participation will last for approximately 5 months.
The long-term goal of the study is to mitigate the spread of the pandemic in miners, a population of high-risk, rural essential workers who are susceptible and vulnerable to COVID-19, partly based on exposure to particulate air pollution, and who are predominantly racial/ethnic minorities in New Mexico (NM) (3, 11). The study objective is to provide proof-of-principle for frequent point-of-care molecular testing as a workplace surveillance tool to monitor and prevent the spread of SARS-CoV-2 infection in this unique population. The central hypothesis is that frequent workplace molecular surveillance is an effective method to reduce SARS-CoV-2 infection and discover novel host risk factors for the virus. The site of molecular surveillance (intervention site) will be a surface coal mine in McKinley County, NM, located just outside the Eastern Agency of the Navajo Nation, comprised of 66% minority miners. This site offers a unique opportunity for a community-based study of SARS-CoV-2 infection in this population. Miners at the intervention site will provide nasal swabs before beginning their work shift on alternate days that will be analyzed with a 'screening' molecular test (12). This test is ideal because it is low cost, simple, portable, point-of-care, rapid, and can be performed by minimally trained professionals in low-infrastructure settings. The control site is a similar coal mine in Campbell County, Wyoming (WY). Both mines, operated by the same company, have similar engineering, administrative, and personal protective measures in place. The rationale for this study is to establish the suitability of longitudinal molecular surveillance to prevent and control SARS-CoV-2 infection in this unique population by completing the following specific aims.
This phase 2 trial studies the immune response to GEO-CM04S1 (previously designated as COH04S1) compared to standard of care (SOC) mRNA SARS-COV-2 vaccine in patients with blood cancer who have received stem cell transplant or cellular therapy. GEO-CM04S1 belongs to a category called modified vaccinia Ankara (MVA) vaccines, created from a new version of MVA, called synthetic MVA. GEO-CM04S1 works by inducing immunity (the ability to recognize and fight against an infection) to SARS-CoV-2. The immune system is stimulated to produce antibodies against SARS-CoV-2 that would block the virus from entering healthy cells. The immune system also grows new disease fighting T cells that can recognize and destroy infected cells. Giving GEO-CM04S1 after cellular therapy may work better in reducing the chances of contracting coronavirus disease 2019 (COVID-19) or developing a severe form of COVID-19 disease in patients with blood cancer compared to SOC mRNA SARS-CoV-2 vaccine.
Blood samples are collected and stored in a biobank for later analysis of circulating substances in peripheral blood and genetic variations in patients with severe critical illness and risk of death. The aim is to analyze stored samples in order to identify substances that can help predict the outcome of critically ill patients, but also to optimize treatment and possibly prevent serious illness and death in the future.
This study aims to conduct formative usability and internal validation of the COVID-19 rapid diagnostic test tool based on DNA aptamers, involving 200 patients to assess aspects of experimental setup, testing center, testing kit configuration, designing algorithms or workflows for clinical trials, and also assess initial accuracy by validating with the patient's PCR test results.
