View clinical trials related to Covid19.
Filter by:In December 2019, the first people got infected with COVID-19 in Wuhan, China. Within weeks, this highly infectious disease spread all over the world. Nearly one year later everyone is still trying to battle this disease and facing the consequences it causes. What became clear is that the disease and its severity differs largely between infected people. However, knowledge about who will experience severe COVID-19 and who does not is still unclear. Therefore, the aim of this study is to investigate the prognostic value of certain parameters (mtDNA and CT radiomics signature) for the severity of COVID-19.
TOFA-COV-2 is a cohort study of the efficacy of tofacitinib in reducing the risk of mechanical ventilation and/or death in patients with moderately severe COVID-19 pneumonia who received standard of care treatment (SoC). The study population consists of adults (≥18 years) with COVID-19, who are admitted to the university hospitals and don't require invasive or noninvasive ventilation on admission. All patients are divided into four groups depending on nadir levels of oxygen saturation and therapy: (1) patients with oxygen saturation ≤93% who received tofacitinib and SoC, (2) patients with oxygen saturation ≤93% who received only SoC, (3) patients with oxygen saturation >93% who received tofacitinib and SoC, (4) patients with oxygen saturation >93% who received only SoC. The aim of the study is to test the hypothesis that addition of tofacitinib to SoC could reduce the risk of mechanical ventilation and/or death.
This is a Phase 2/3, randomized, double blind, placebo controlled, multicenter study to evaluate the efficacy and safety of FP-025 in adult patients with severe to critical COVID 19 with associated ARDS.
Feasibility trial investigating the potential higher frequency of robotic assisted early mobilization in intubated COVID19 patients on the ICU.
To assess whether the COVID-19 pandemic delayed breast cancer diagnosis in Taiwan, an Asian country with a low COVID-19 incidence.
This Phase I study is a double-blind, randomized, placebo-controlled study designed to assess the safety, tolerability and PK profile of single intramuscular doses of DWRX2003 in healthy volunteers.
Since the innovation of our new half- elastometric half-piece respirator, this type of FFR has been used widely in our country. Decontamination methods including ultraviolet C (UVC) germicidal irradiation and 70% alcohol have been implemented to decontaminate the respirator. We than examined inactivation potential for the Porcine epidemic diarrhea virus (PEDV), numerous bacterial strains ,mostly skin-derived after the decontamination process.To enable rigorous integrity after repeated decontamination process, fit test by the Bitrex test ,tensile strength and elongation at break were also evaluated. Our results showed that the UVC at the dose of 3 J/cm2 can eradicate the bacteria at 60 min and virus at 10 min.No fungus was found on the mask surface at the beginning. Good Fit test , tensile strength and elongation at break were still main maintained after multiple cycles of decontamination. No evidence of physical degradation by gross visual inspection was found. 70% alcohol is also an easy and effective way to eradicate microorganisms on the mask.As the current pandemic is expected to continue for months to years, the need to supply adequate reserves of PPE and develop effective reprocessing is crucial. Our studies demonstrated that the novel silicone mask can be safely reprocessed and decontaminated for many cycles by UVC irradiation and help restore the shortage of the important protective devices in the COVID-19 pandemic era.
Subjects (125) will be randomized to one of five mouthrinses and will be asked to give a saliva sample immediately before and after a 30-60 second mouthwash. Saliva samples will be collected from subjects at 15-minute intervals thereafter up to one hour (15, 30, 45 and 60 min). The saliva will be used for RT-PCR detection of Severe Acute Respiratory Syndrome CoronaVirus 2 (SARS-CoV-2) and viral infectivity assays, along with quantitative cytokine and chemokine concentration (pg/mL, Luminex). Subjects will complete a short survey on the taste and experience of using the mouthwash. Peripheral blood will be collected at the end of salivary collection. Subjects, except controls, will be provided materials and oral hygiene instruction related to daily use of oral hygiene products. In the seven-day period between study visit one and study visit two, subjects will be directed to brush with Colgate toothpaste (at least twice per day) and rinse with the Colgate mouthrinse (according to on-label procedures). Controls are asked to carry out their typical oral hygiene regimen with the products they typically use. All subjects keep a daily diary of oral hygiene performance, product usage, COVID-19 symptoms and exposures. Subjects complete study visit two one week after the baseline visit during which additional salivary (1 time point, 2 mL of saliva over 5 min, no rinse) will occur and blood samples collected. each subject will undergo a periodontal exam.
COVID-19 is a respiratory disease caused by a novel coronavirus (SARS-CoV-2) and causes substantial morbidity and mortality. Nosocomial acquisition of SARS-CoV-2 is a frequent concern across hospital settings in Canada and is associated with substantial morbidity and mortality. This clinical trial is initially designed to evaluate the role of monoclonal antibodies against the SARS-CoV-2 spike protein, for the treatment of hospitalized patients who acquire COVID19 via nosocomial infection. New treatments, as they become available, may be integrated, with appropriate adaptation of this document. The trial was initiated with the bamlanivimab product with the options of casirivimab/imdesimab and sotrovimab added as the prevalence of bamlanivimab resistant variants of concerns increased. It is believed that monoclonal antibody treatments are most likely to be effective early in the disease course. The ability to rapidly identify and initiate such treatments in patients with nosocomial acquisition of the infection, combined with the high mortality of 25-30% experienced by this group of patients led us to propose this trial in collaboration with the CATCO national network. The overall objective of the study is to evaluate the safety and clinical effectiveness of anti-SARS-CoV-2 monoclonal antibody treatment relative to the control arm, in patients who develop nosocomial SARS-CoV-2 infection, on need for mechanical ventilation or death. This study is designed as a pragmatic randomized, open-label, controlled clinical trial. Subjects will be randomized to receive either standard-of-care (control) or the study medication on a 1:2 basis. Bamlanivimab, casirivimab/imdesimab or sotrovimab will be administered intravenously as a one-time infusion after randomization. Casirivimab/imdesimab (REGN) and sotrovimab will be the default agents based on local availability unless both are unavailable AND virus strain known to be native or alpha (B.1.1.7). Incidence of infusion-related reactions in the 24 hours post administration.
This study aims to evaluate the immunogenicity of Moderna mRNA-1273 vaccine in volunteers aged 65 years or more compared to volunteers aged 18-45 years, over 24 months duration. It will provide necessary data on the early immunological response to the vaccine and its evolution in quantitative and qualitative terms. This study will allow establishing how aging influences the response to the vaccine and help to adapt the vaccinal plan. For instance it will suggest the necessity of a vaccination booster.
