Active clinical trials for "COVID-19"

Nursing homes are ground zero for the COVID-19 pandemic. Nursing homes are ill-equipped for the pandemic; though facilities are required to have infection control staff, only 3% have taken a basic infection control course. Significant research has focused on infection control in the acute care setting. However, little is known about the implementation of practices and effective interventions in long-term care facilities.The investigators propose an intervention utilizing Project ECHO, an evidence-based telehealth model, to connect Penn State University experts with remote nursing home staff and administrators to proactively support evidence-based infection control guideline implementation. Our study seeks to answer the critical research question of how evidence-based infection control guidelines can be implemented effectively in nursing homes

This is a phase I, randomized, placebo-controlled, double-blind study, to evaluate safety and immunogenicity of a recombinant SARS-CoV-2 vaccine (CHO cell) in Chinese healthy population aged 18 years and older. After randomization, the trial for each subject will last for approximately 13 months. Screening period is 1 week prior to randomization (Day -7 to Day -1), and each dose of either SARS-CoV-2 vaccine (CHO Cell) or placebo will be given intramuscularly (IM) on Day 0 and Day 14 for a two-dose regimen, or on Day 0, Day 14, and Day 28 for a three-dose regimen. Subjects who are ≥18 years old and ≤ 59 years old will be enrolled in adult group, and healthy elderly population who are >59 years old will be enrolled in elderly group. After adult group completes the follow-up 7 days after first vaccination, elderly group will be recruited.

COVAC Uganda is a study that is looking at the use of an innovative self-amplifying RNA (saRNA) vaccine (LNP-nCOV saRNA-02) against the virus (SARS-CoV-2) that causes COVID-19 and assessing the immune response in SARS-CoV-2 antibody seronegative and seropositive individuals. saRNA is designed to amplify the quantity of RNA upon injection to produce further antigen, thereby enabling lower doses for administration. In the trial "COVAC1", Imperial College London is currently evaluating one COVID-19 saRNA vaccine candidate in doses from 0.1-10ug for individuals who are seronegative for SARS-CoV-2 antibodies at baseline. Interim analyses of COVAC1 has shown a dose dependent response; however, up to 50% of seronegative participants receiving doses of 2.5-10ug do not seroconvert. The investigators hypothesize that a lack of seroconversion is due to type I and III interferon (IFN) production, which can inhibit translation and degrade cellular mRNA. Another variable that can enhance antibody production is serological history: recent studies have shown that seropositive individuals respond significantly better than naïve individuals who received the Pfizer or Moderna RNA-based COVID-19 vaccine. Therefore, designing the saRNA backbone to dampen IFN production and evaluating this in individuals seropositive at baseline will inform the optimised use of this innovative technology. In COVAC Uganda, the investigators aim to test an saRNA vaccine modified to dampen the activation of type I and III IFN, to increase antibody production, for individuals who are seronegative and seropositive for SARS-CoV-2 antibodies at baseline, to evaluate whether people with pre-existing seropositivity have enhanced immune responses compared to those without. This trial is NOT looking at whether or not the vaccine is effective in terms of protection. It is just assessing whether and how well the immune system responds based on SARS-CoV-2 antibodies at baseline and its safety.

The present study is a prospective phase IV study. All participants will receive the anti-Coronavirus Disease 2019 (COVID-19) Vaccine (messenger Ribonucleic acid-based vaccine, BNT162b2 or Comirnaty®, commercialized by Pfizer-BioNTech) being authorized in the European Union since December 2020. The vaccine is administered intramuscularly after dilution as a series of two doses at least 21 days apart.

The study will focus on cardiac blood and imaging biomarkers to facilitate early recognition of patients at risk for myocardial injury after COVID-19 vaccination. Ultimately, the intention is to identify patients at risk, reduce adverse events, and determine the need for longer-term follow-up in patients with myocardial injury after vaccination.

This trial aims to measure the humoral and adaptive immune response in patients with cancer diagnosis undergoing mRNA vaccination against SARS-CoV-2 and assess its efficacy in preventing COVID-19.

This is a phase Ⅱ, randomized, placebo-controlled, double-blind study, to evaluate immunogenicity and safety of a recombinant COVID-19 vaccine (CHO cells) in the subjects from healthy adults and elderly adults aged 18 years and above (aged 18-60 and 60-85 years) with an immunization procedure (0, 28, 56 days).

COVID-19 (SARS-CoV2 virus) was declared a global pandemic by the WHO on 11th March 2020. Currently there are no drugs proven to prevent COVID-19 or to reduce the severity of illness if given as prophylaxis. Although vaccines are now available, there remains a need for other prophylactic agents until vaccine use becomes widespread globally and effectiveness and durability is established, particularly in immunocompromised individuals, for whom vaccine responses may be suboptimal. Efforts are underway to repurpose established drugs with well understood drug interactions and safety profiles. PROTECT-V is a platform trial to test prophylactic interventions against SARS-CoV2 infection in vulnerable patient populations at particularly high risk of COVID-19 and its complications, seeking to identify treatments that either might prevent the disease from occurring or may reduce the number of cases where the disease becomes serious or life-threatening. In PROTECT-V, multiple agents can be evaluated on the same platform across vulnerable populations, with the option of adding additional treatments at later time points as these become available. The expectation is for as many sites as possible to recruit to all available trial treatments at any time, however, the platform structure and randomisation/data collection systems allow sites to open the trial treatment arms according to their capacity. The trial opened with intranasal niclosamide and matched placebo, aiming to recruit 1500 vulnerable renal patients in February 2021. A parallel study protocol, will be conducted in India, sponsored by The George Institute. Recruitment of approximately 750 Indian patients will commence in February 2022. The second agent, intranasal and inhaled ciclesonide and matched placebo, will be added to the platform in early 2022 in the same renal patient population. Sotrovimab and matched placebo will be added to the platform in early 2022 in patients who have mounted sub-optimal vaccine responses to vaccines against SARS CoV-2.

This project seeks to test the efficacy of a brief eHealth intervention in an international randomized controlled trial (RCT) to increase COVID-19 knowledge and protective behaviors, and reduce psychological distress among LGBT people. This project involves enrolling racially diverse samples of lesbian, gay, bisexual and transgender people in three cities, randomizing 900 people (stratified among cisengender men, cisgender women, and transgender people) to either the immediate behavioral intervention or the waitlist control condition. Participants will complete a baseline survey, a follow-up survey 2 weeks post-intervention, and a final survey 2 months after the post-intervention survey. Primary outcomes are COVID-19 transmission knowledge, COVID-19 protective behaviors, and psychological distress.

The goal of the research is to assess candidate COVID-19 rapid diagnostic tests (e.g. immunodiagnostic antibody tests, like Cellex qSARS-CoV-2 IgG/IgM Rapid Test, or antigen tests, like Turklab Test-It COVID-19 Home Test, AllBio Science Inc. and Artron Laboratories Inc. rapid COVID-19 antigen tests in order to judge their clinical accuracy compared to Centers for Disease Control (CDC)-recommended molecular genetic testing and clinical diagnosis. Second, it is our goal to determine if self-testing assisted by COVIDscanDX mobile device camera acquisition software platform and telemedicine clinical/technical support (virtual point-of-care) improves the ease of use and immediate interpretation of the tests, thus making self-testing comparable in accuracy and safety to testing in a clinical setting. Third, we are testing antibodies to SARS-CoV-2 after diagnosis with COVID-19 or following vaccination to measure the onset and time course of detectable antibodies from finger-stick blood drops and rapid antibody lateral flow tests. The overall purpose of the study is to dramatically increase the capacity of COVID-19 testing by establishing the safety, ease-of-use and validity of self-testing assisted by mobile device imaging and telemedicine remote support and provide evidence of antibody time-course response to vaccination.
