Filter by:This study will perform prospective repeated serological antibody testing on a cohort of at least 1000 healthcare workers at Great Ormond Street Hospital. Within this cohort, a subset of 150-250 staff members with confirmed (PCR positive) SARS-CoV-2 disease will be followed with intensive monthly testing for 6 months to determine whether antibody levels in the blood are maintained or decrease during this time. All 1000 recruited healthcare workers will be followed 6-monthly
The purpose of this study is to evaluate the safety of administration of plasma containing antibodies to the SARS-CoV-2 virus (i.e., convalescent plasma) and if it is able to prevent disease or lessen the severity of disease in individuals who are at high risk of developing COVID-19 due to a recent exposure. This study will also measure the level of anti-SARS-CoV-2 antibodies in patient's blood after the administration of the convalescent plasma.
This is a Phase 1/2/3, randomized, placebo-controlled, observer-blind, dose-finding, vaccine candidate-selection, and efficacy study in healthy individuals. The study consists of 2 parts: Phase 1: to identify preferred vaccine candidate(s) and dose level(s); Phase 2/3: an expanded cohort and efficacy part. The study will evaluate the safety, tolerability, and immunogenicity of 3 different SARS-CoV-2 RNA vaccine candidates against COVID-19 and the efficacy of 1 candidate: - As a 2-dose (separated by 21 days) schedule; - At various different dose levels in Phase 1; - As a booster; - In 3 age groups (Phase 1: 18 to 55 years of age, 65 to 85 years of age; Phase 2/3: ≥12 years of age [stratified as 12-15, 16-55 or >55 years of age]). The candidate selected for efficacy evaluation in Phase 2/3 is BNT162b2 at a dose of 30 µg. Participants who originally received placebo will be offered the opportunity to receive BNT162b2 at defined points as part of the study. In order to describe the boostability of BNT162, and potential heterologous protection against emerging SARS-CoV-2 VOCs, an additional dose of BNT162b2 at 30 µg will be given to Phase 1 participants approximately 6 to 12 months after their second dose of BNT162b1 or BNT162b2. This will provide an early assessment of the safety of a third dose of BNT162, as well as its immunogenicity. The assessment of boostability will be further expanded in a subset of Phase 3 participants at selected sites in the US who will receive a third dose of BNT162b2 at 30 µg or a third and potentially a fourth dose of prototype BNT162b2VOC at 30 µg (BNT162b2s01, based upon the South African variant and hereafter referred to as BNT162b2SA). A further subset of Phase 3 participants will receive a third, lower, dose of BNT162b2 at 5 or 10 µg. To further describe potential homologous and heterologous protection against emerging SARS-CoV-2 VOCs, a new cohort of participants will be enrolled who are COVID-19 vaccine-naïve (ie, BNT162b2-naïve) and have not experienced COVID-19. They will receive BNT162b2SA given as a 2-dose series, separated by 21 days. To reflect current and anticipated recommendations for COVID 19 vaccine boosters, participants in C4591001 who meet specified recommendations and have not already received one, will be offered a third dose of BNT162b2 after their second dose of BNT162.
This randomized blinded multi-center phase 2 trial will assess the efficacy and safety of anti-SARS-CoV-2 convalescent plasma among adults with severe COVID-19. Adults ≥18 years of age may participate. A total of 219 eligible subjects will be randomized in a 2:1 ratio to receive either high-titer anti-SARS-CoV-2 plasma or non-convalescent fresh frozen plasma (control plasma).
The Investigators propose to set up a preventive trial of infection in hospital workers at risk of coronavirus infection by comparing the rate of SARS-Cov-2 infection in a population of negative SARS-Cov-2 hospital workers receiving preventively azithromycin, hydroxychloroquine or a Placebo
Rationale: The clinical manifestations of SARS-CoV-2 infection in children are poorly characterized. Preliminary findings indicate that they may be atypical. There is a need to identify the spectrum of clinical presentations, predictors of severe disease (COVID-19) outcomes, and successful treatment strategies in this population. Goals: Primary - Describe and compare characteristics of confirmed SARS-CoV-2 infected children with symptomatic test-negative children. Secondary - 1) Describe and compare confirmed SARS-CoV-2 infected children with mild versus severe COVID-19 outcomes; 2) Describe healthcare resource utilization for, and outcomes of, screening and care of pediatric COVID-19 internationally, alongside regional public health policy changes. Methods: This prospective observational study will occur in 50 emergency departments across 11 countries. We will enroll 12,500 children who meet institutional screening guidelines and undergo SARS-CoV-2 testing. Data collection focuses on epidemiological risk factors, demographics, signs, symptoms, interventions, laboratory testing, imaging, and outcomes. Collection will occur at enrollment, 14 days, and 90 days. Timeline: Recruitment will last for 12 months (worst-case model) and will begin within 7-14 days of funding notification after ongoing expedited review of ethics and data sharing agreements. Impact: Results will be shared in real-time with key policymakers, enabling rapid evidence-based adaptations to pediatric case screening and management.
COVID-19 is a respiratory disease caused by a novel coronavirus (SARS-CoV-2) and causes substantial morbidity and mortality. There is currently no vaccine to prevent COVID-19 or therapeutic agent to treat COVID-19. This clinical trial is designed to evaluate potential therapeutics for the treatment of hospitalized COVID-19. We hypothesis that chloroquine slows viral replication in patients with COVID-19, attenuating the infection, and resulting in more rapid declines in viral load in throat swabs. This viral attenuation should be associated with improved patient outcomes. Given the enormous experience of its use in malaria chemoprophylaxis, excellent safety and tolerability profile, and its very low cost, if proved effective then chloroquine would be a readily deployable and affordable treatment for patients with COVID-19. The study is funded and leaded by The Ministry of Health, Vietnam.
The purpose of this study is to test the effect of purified (acellular) amniotic fluid as a treatment for SARS CoV-2 (COVID19)-associated respiratory failure. Past use of human amniotic products (i.e., membrane and fluid) is FDA-approved for tissue injury and has been used to reduce inflammation and fibrosis in patients with a variety of medical conditions. The investigators hypothesize that using nebulized and/or intravenous purified (acellular) amniotic fluid will reduce both inflammation in patients hospitalized for in SARS CoV-2 (COVID19)-associated respiratory failure, potentially leading to a decrease in respiratory support.
