Active clinical trials for "COVID-19"

The COVID-19 pandemic is of grave concern due its impact on human health and on the economy. Propolis, a natural resin produced by bees from plant materials, has anti-inflammatory, immunomodulatory, anti-oxidant properties, and various aspects of the SARS-CoV-2 infection mechanism are potential targets for propolis compounds. Propolis components have inhibitory effects on the ACE2, TMPRSS2 and PAK1 signaling pathways; in addition, antiviral activity has been proven in vitro and in vivo. This is a pilot randomized study that aims to assess the impact of using Brazilian green propolis extract against the deleterious effects of the new coronavirus.

COVID-19 morbidity and mortality has been associated with Cytokine Release Syndrome (CRS) and Acute Respiratory Distress Syndrome (ARDS). ATI-450 is an oral small molecule MAPKAPK2 (MK2) inhibitor that potently inhibits multiple inflammatory cytokines. The investigator hypothesizes that MK2 pathway blockade during active COVID-19 infection in hospitalized participants will result in improvement in respiratory-failure free survival.

The purpose of this study is to evaluate the tolerability, safety, pharmacokinetics of SCTA01(anti-SARS-CoV-2 monoclonal antibody) in Healthy Chinese Subjects.

In this 16-week randomized control study, health care workers will receive a bolus dose followed by a weekly dose of vitamin D or a placebo bolus and weekly dose. This study will test whether high-dose of vitamin D supplementation decreases the incidence of laboratory-confirmed COVID19 infection (primary outcome), reduces illness severity, duration, as well as work absenteeism among health care workers (HCW) in setting at high-risk of contact with COVID-19 cases in high COVID-19 incidence areas.

Problem: The COVID- 19 pandemic has not only affected our healthcare system, but the impact on the worldwide financial systems and our "normal" way of life is still to be determined. Although the percentage of patients infected with COVID-19 that need hospital care is low, Its high rate of contagiousness makes the total number of patients in need of hospital care cripple any healthcare system, limiting the space available for other patients in need of critical care, who cannot be admitted or even prefer not to attend the hospital in fear of infection. Early investigations report an Increase risk of thromboembolic complications, and a systemic inflammatory response not clearly understood. There is a possible vascular endothelial dysfunction due to chronic comorbidities (Hypertension, diabetes, obesity, chronic kidney disease, lung disease) as a risk factor for a more severe presentation. Justification: Sulodexide is a two-compound drug, each of them with different endothelial action that can be beneficial in COVID-19 patients. Glycosaminoglycans: Can help restore venous and arterial endothelial glycocalyx which can downregulate or limit the response to inflammatory molecules, by maintaining the integrity lost in certain chronic diseases (high blood pressure, diabetes). Heparin compound: It has an antithrombotic effect that could help reduce the incidence of thromboembolic complications, and also add to the anti-inflammatory response due to it anti-thrombin action (similar or a bit less to that of low molecular weight heparin) with less risk of major bleeding. It's a medication that can be used orally with minimal adverse effects and is less expensive than low molecular weight heparin. Hypothesis: We hypothesize that sulodexide instituted early in populations at significant risk and symptomatic patients affected with COVID-19 (shortness of breath, fever, weakness, diarrhoea) and risk factors of diabetes, hypertension, COPD, atherosclerosis, chronic kidney disease, will provide improvement in endothelial integrity, decrease inflammatory responses, and improved clinical outcomes with decreased hospital admission, decrease VTE and arterial complications, morbidity, and mortality. Objective: To use sulodexide in patients that have early onset of COVID-19 symptoms to mitigate the progression of the disease process that can allow them to recover at home, and limit the need of hospital care and a more severe clinical manifestation

This study is designed rapidly assess safety and preliminary efficacy in hospitalized patients with COVID-19 respiratory distress to provide clinical guidance for possible wider use in treating patients in this pandemic environment. This data will be used for FDA IND filings and pursuit of a BLA.

In a 2x2 factorial design randomized controlled trial, the investigators aim to elaborate the safety and efficacy of two pharmacological regimens on outcomes of critically-ill patients with COVID-19. The first randomization entails open-label assignment to intermediate versus standard dose prophylactic anticoagulation. The investigators hypothesize that intermediate dose compared with standard prophylactic dose anticoagulation will have a superior efficacy with respect to a composite of venous thromboembolism (VTE), requirement for extracorporeal membrane oxygenation (ECMO), or all-cause mortality. The second randomization will be double-blind assignment of the included patients to atorvastatin 20mg daily versus matching placebo. The hypothesis is that statin therapy, compared with placebo, will reduce the composite of VTE, need for ECMO, or all-cause mortality.

Currently, there is no specific treatment or vaccine for SARS-CoV-2 available, some drugs are being investigated as treatment, but the effect is unknown. A strategy and other method used before, in coronavirus pandemic (SARS-CoV in 2003 and MERS-CoV in 2012), was the use of immune (convalescent) plasma. Passive administration of antibodies through convalescent plasma transfusion may offer the only short-term strategy available to confer immediate immunity and being a relative immediately resource available for treat COVID-19 disease. This research proposes the passive administration of antibodies through the transfusion of convalescent plasma, in patients with severe COVID-19 disease.

A multi-centre Australian trial with four arms aims to evaluate several different immune modulating drugs for prevention and treatment of COVID-19 specifically in the cancer population. ARM 1 is evaluating the effect of interferon-alpha (vs placebo) on the incidence of COVID-19 infection in cancer patients with no COVID-19 infection or no known COVID-19 positive contacts. ARM 2 is evaluating the effect of interferon-alpha (vs placebo) on the incidence of COVID-19 infection in cancer patients with confirmed exposure to COVID-19 virus. ARM 3 is evaluating the effect of Selinexor (vs placebo) on the incidence of COVID-19 infection in cancer patients with moderate COVID-19 infection. ARM 4 is evaluating the effect of Lenzilumab (vs placebo) on the treatment of COVID-19 infection in cancer patients with severe COVID-19 infection. Participants may become eligible and transition to different arms and treatments if they become exposed to COVID-19 or are hospitalised with an active moderate/severe COVID-19 infection. It is hoped this research will provide insight into the best practice for prevention and treatment of COVID-19 in cancer patients as emerging standard of care measures are not always suitable to this especially vulnerable population.
