Active clinical trials for "Coronavirus Infections"

The primary purpose is to describe the safety of administration of three doses of STS to critically ill patients with confirmed COVID-19. A secondary purpose is to describe data on the clinical efficacy of administration of up to three doses of STS in critically ill patients with confirmed COVID-19.

The emergence of a novel coronavirus(SARS-CoV-2) in late 2019 has resulted in a global epidemic of the infectious condition COVID-19. Since March 2022, the Omicron mutant has caused widespread transmission in Shanghai, China, and is characterized by the majority of asymptomatic patients. Although showing no obvious symptoms, the asymptomatic patients have high transmissibility because of high viral loads in their oropharynx and nasopharynx. Therefore，this study puts forwards the hypothesis that local flushing treatment in the sino-nasal and mouth cavity can reduce the viral load to reduce their transmissibility. Nasal Irrigation and gargling is a safe and commonly used mechanism to treat a variety of sinonasal diseases including sinusitis, rhinitis, and upper respiratory tract infections. Povidone-iodine(PVP-I) is a water-soluble complex of povidone, a carrier molecule, and iodine, which has powerful microbicidal activity. Also, recent evidence of in-vitro virucidal action of povidone-iodine in Severe Acute Respiratory Syndrome-Coronavirus 2 (SARS CoV-2) has been supported. Therefore, the study is designed to assess the virucidal effect of nasal irrigation and gargling with PVP-I against SARS-CoV-2 located in the throat. The hypothesis was that the treatment would be effective in improving the negative conversion rate of SARS-CoV-2 nucleic acid on day 10.

The purpose for this study is to determine if the study drug baricitinib is effective and safe in hospitalized pediatric participants with Coronavirus disease 2019 (COVID -19) and to confirm the dose.

This study will evaluate the safety of administering an additional dose of an mRNA COVID-19 vaccine or mRNA bivalent COVID-19 booster vaccine to individuals who have had adverse reactions to a previous dose or administering an initial dose of an mRNA COVID-19 vaccine to individuals with a personal history of allergic reaction. In addition, this study will evaluate the safety of administering an initial or additional dose or bivalent booster of an mRNA COVID-19 vaccine to individuals experiencing an adverse reaction to a natural COVID-19 infection ("long COVID"). Eligible participants enrolled in this trial will receive an initial or additional dose of either the Pfizer-BioNTech COVID-19 bivalent vaccine or the Moderna COVID-19 bivalent vaccine. Participants will also be required to have 1-2 in person visits along with phone call follow up visits. We hypothesize that individuals who have had adverse reactions to a previous dose of an mRNA COVID-19 vaccine will tolerate an additional dose of the primary mRNA vaccine or bivalent booster, as indicated, and those with a personal history of allergic reaction will tolerate an initial dose of an mRNA COVID-19 vaccine. We also hypothesize that those individuals experiencing an adverse reaction will tolerate an initial or additional dose of a primary mRNA COVID-19 bivalent vaccine, as indicated. The study hypothesizes that individuals that have had adverse reactions to a dose of an mRNA COVID-19 vaccine will tolerate an additional dose and those with a personal history of allergic reaction will tolerate vaccination with an mRNA COVID-19 vaccine.

The overall objective of the study is to evaluate the safety and efficacy of MSC therapy combined with best supportive care in hospitalized patients with COVID-19.

It is planned to include 200 patients hospitalized with primary myocardial infarction with and without ST segment elevation (STEMI or NSTEMI) in combination with COVID-19 within the first 15 days from the disease onset. The total follow-up period is 96 weeks. Hypotheses: An integrated approach in assessing myocardial contractility, regulation of the heart and the structural and functional state of arteries will make it possible to more accurately assess the heart pumping function; explain the mechanisms of the relationship between left ventricular (LV) contractile function and its volumetric indices; to study the mechanisms of ventriculo-arterial coupling and the influence of autonomic regulation, the role of markers of the sudden cardiac death (late ventricular potentials, pathological turbulence of the heart rate, dispersion of the QT interval). In patients who have had myocardial infarction in combination with the new coronavirus infection SARS-CoV-2 (COVID-19), long-term highly effective lipid-lowering therapy, regardless of the drugs prescribed, has an antiarrhythmic effect and has a beneficial effect on the autonomic regulation of the heart rate. Highly effective lipid-lowering therapy leads to an improvement in LV contractility and structural and functional properties of the large arteries.

The Multi-arm trial of Inflammatory Signal Inhibitors for COVID-19 (MATIS) study is a two-stage, open-label, randomised controlled trial assessing the efficacy of ruxolitinib (RUX) and fostamatinib (FOS) individually, compared to standard of care in the treatment of COVID-19 pneumonia. The primary outcome is the proportion of hospitalised patients progressing from mild or moderate to severe COVID-19 pneumonia. Patients are treated for 14 days and will receive follow-up assessment at 7, 14 and 28 days after the first study dose. Patients with mild or moderate COVID-19 pneumonia will be recruited. Initially, n=171 (57 per arm) patients will be recruited in Stage 1. Following interim analysis to assess the efficacy and safety of the treatments, approximately n=285 (95 per arm) will be recruited during Stage 2.

Since december 2019, acute respiratory disease due to 2019 novel coronavirus (2019-nCoV) emerged in Wuhan city and rapidly spread throughout China. There is no confirmed antivirus therapy for 2019-nCoV infection. Natural killer (NK) cells are innate lymphocytes that may serve as useful effectors against danger infection. The purpose of this clinical investigation is to evaluate the safety and efficiency of NK Cells in combination with standard therapy for pneumonia patients infected with 2019-nCoV.

This will be a multistate, multicenter clinical study to determine the efficacy and safety of medical cannabis for a wide variety of chronic medical conditions.

The patients with coronavirus infection usually have fever, respiratory symptoms, headache, toothache, muscle soreness, physical decline, and so on, while others are asymptomatic patients. It is urgent to find drugs to improve the long-term rehabilitation of symptomatic patients with coronavirus infection and decrease the duration of viral shedding in both symptomatic and asymptomatic patients. This study aims to investigate the efficacy and safety of Lianhua Qingwen capsules in patients with coronavirus infection. The duration of viral shedding and symptoms before discharge, as well as the negative conversion ratio and disappearance ratio of main symptoms after 7-day treatment, will be evaluated. 6-month follow-up will be performed to evaluate the effect of Lianhua Qingwen on all infection events and the long-term rehabilitation of the symptoms induced by coronavirus infection.
