Active clinical trials for "COVID-19"

This study is a randomized and controlled Phase IV clinical trial of the COVID-19 vaccine (Vero cell), Inactivated manufactured by Sinovac Research & Development Co., Ltd. The purpose of this study is to evaluate the immunogenicity and safety of COVID-19 vaccine (Vero cell), Inactivated co-administration with EV71 vaccine

This study is a randomized, double-blind, placebo-controlled trial to evaluate the efficacy of cetirizine and famotidine in reducing the duration of symptoms in patients with COVID-19. Secondary aims are to determine if cetirizine and famotidine decrease severity and duration of symptoms, incidence of hospitalizations, ICU admissions, and death.

Sars-Cov2 virus is transmitted through the respiratory route and by direct contact with contaminated surfaces and subsequent contact with nasal, oral or ocular mucosa. Many studies have found that the oral cavity and specifically the saliva may be a high-risk route for SARS-CoV-2 infection. Thus, strategies reducing salivary viral load could contribute to reduce the risk of transmission. Furthermore, studies have shown that SARS-CoV persists for two days in oral mucous membranes before its diffusion to the lower respiratory tract. This offers an interesting preventive and therapeutic window of opportunity for the control of this disease. In addition, Naso-pharyngeal viral load was linked with lung disease severity in a study of 12 patients with pneumonia.**. Some current studies around the world, as listed on ClinicalTrials.gov, are testing the effect of some common mouth rinses/gargles on the Covid-19 viral load, including Chlorhexidine gluconate, Hydrogen peroxide Povidone Iodine, Saline (1.102% w/v, slightly hypertonic) and Alcohol. This study aims to test whether Prolonged Hypertonic Saline Mouth Rinse would reduce/eliminate*** the viral load in the Oro- Naso-Pharyngeal cavity, and could therefore be used as a strategy to reduce transmission risk in clinical and social settings. The investigator hypothesizes that COVID-19-positive participants who use Hypertonic Saline Prolonged Rinse treatment will have an reduction/elimination of their Covid viral load, will develop a negative Covid test 7 days after intervention completion and will improve their clinical symptoms, potentially reducing lung disease severity.

This phase II trial investigates how well dasatinib works in treating patients with moderate and severe COVID-19. Dasatinib is a drug used to treat chronic leukemia which may help reduce the strong inflammation caused by COVID-19 that can damage the lungs or other organs.

This is an open-label, multicentre study evaluating the effect, safety and tolerability of the two regioisomers 1-(nitrosooxy)propan-2-ol and 2-(nitrosooxy)propan-1-ol (PDNO) infusion given to COVID-19 patients with acute pulmonary hypertension (aPH) and/or acute cor pulmonale (ACP).

The aim of this study is to explore potential for reduction of incidence and/or morbidity of SARS-CoV-2 infection in healthcare personnel. The study will include a comparison between placebo and RUTI® vaccine in a 2:1 design.

The 'CAPMYKCO' study is a randomized controlled, open-label, single center proof of concept trial. The aim of this study is to evaluate whether a CRP-apheresis in addition to the current standard therapy is intended to mitigate the severity of the disease course of SARS-CoV-2, especially with regard to tissue injury in the lungs, heart and kidneys and their consequences. CRP-apheresis should reduce the necessity and duration of non-invasive/invasive ventilation requirements compared to the control group. The influence of CRP-apheresis on the attenuation of pulmonary, myocardial and/or kidney tissue injury as well as the course of the COVID-19 disease will also be demonstrated by evaluating various biomarkers, several clinical scoring systems, and the duration of intensive care medical treatment.

To estimate the pulmonary response microvascular thrombosis in critical patients due to SARS-Cov-2., at the Hospital General de México "Dr. Eduardo Liceaga", a 15 patients compassionate treatment study was authorized and approved by the ethics and research committee DI-222-2020. Because of the severity of the illness the legal representative sign informed consent in all the patients for performing in-situ thrombolysis with alteplase selectively by catheter in each main pulmonary artery, under fluoroscopic guidance and acquiring images with the iFlow software to assess immediate and post-procedure response.

The study is designed to evaluate the safety, reactogenicity and immunogenicity of three groups ages ≤18 - >12, ≤12 ->6, ≤ 6 - >2 years of healthy volunteers who receive two doses of the whole virion inactivated SARS-CoV-2 virus vaccine (COVAXIN®) 28 days apart. Data will be un-blinded to the third party bio-statistician and an interim analysis will be performed on day 56 for Immunogenicity, Safety and submitted to CDSCO.

For an antiviral agent to act as an effective biological barrier on nasal mucosal surface, the formulation preferably has to be maintained on the site of action for several hours, and the nasal spray dispenser can be utilized for administering the solution to the upper respiratory tract. A "first-in-man" clinical study of the nasal spray containing anti-SARS-CoV-2 antibodies derived from bovine colostrum was conducted. The study on healthy volunteers was undertaken to evaluate how long the bovine antibodies would be maintained on the nasopharyngeal surface after administration of nasal spray. In addition, the study enabled to determine which of the two concentrations of antibodies should be used in the final nasal-spray formulation. The volunteers were followed up for 4h after administration of antibody spray and sampling was done at different time-points during this period. The concentration of antibodies from patient samples was measured using ELISA analysis. In addition, as this was a "first-in-man" study any adverse events following the administration of spray were also monitored.
