Active clinical trials for "Coronavirus Infections"

The primary objective is to determine the clinical efficacy of Chloroquine (CQ) in health care workers with moderate to high risk of exposure to COVID-19 in preventing symptomatic COVID-19 infections. Secondary endpoints will explore the efficacy of CQ in preventing any infection as defined by seroconversion to positive anti-COVID antibody status.

The overall objective of the study is to determine the therapeutic effect and tolerance of Anakinra in patients with moderate, severe pneumonia or critical pneumonia associated with Coronavirus disease 2019 (COVID-19). Anakinra (ANA) is a recombinant human decoy IL-1Ra and therefore blocks IL-1α and IL-1β. The study has a cohort multiple Randomized Controlled Trials (cmRCT) design. Randomization will occur prior to offering Anakinra administration to patients enrolled in the COVIMUNO-19 cohort. Anakinra will be administered to consenting adult patients hospitalized with CORVID-19 either diagnosed with moderate or severe pneumonia requiring no mechanical ventilation or critical pneumonia requiring mechanical ventilation. Patients who will chose not to receive Anakinra will receive standard of cares. Outcomes of Anakinra -treated patients will be compared with outcomes of standard of care treated patients as well as outcomes of patients treated with other immune modulators.

COVID-19's mechanism to enter the cell is initiated by its interaction with its cellular receptor, the angiotensin-converting enzyme. As a result of this union, a clathrin-mediated endocytosis process begins. This route is one of the therapeutic targets for which available drugs are being investigated in order to treat COVID-19 infection. This is one of the mechanisms blocked by drugs like ruxolitinib and chloroquine. Various drugs approved for clinical use that block the clathrin-mediated endocytosis pathway have been explored. It has been found that the best in vitro and in vivo results were obtained with statins, which also allowed generating a greater potent adaptive immune response. Therefore, statins and specifically simvastatin make it possible to block the entry process used by COVID-19, block inflammation by various mechanisms and increase the adaptive immune response. All of these processes are desirable in patients infected with COVID-19. Statins have been proposed to have beneficial effects in patients infected with MERS-COV, another coronavirus similar to COVID-19, but there have been no randomized studies supporting the use of statins in patients with COVID-19 infection. In this project we propose the combined use of one of these drugs, ruxolitinib with simvastatin, looking for a synergistic effect in the inhibition of viral entry and in the anti-inflammatory effect.

This study aims to use the regenerative and repair abilities of stem cells to fight against the harmful effects of the novel coronavirus Covid-19 and therefore develop a treatment strategy. It is known that fatalities from this virus is largely caused by its damage to lungs and other organs. As the disease progresses, these organs fail and lead to mortality. Our hope is that the stem cell transplantation from healthy donors will repair the damage caused by the virus and result in a healthy recovery.

A prospective case-control pilot study to evaluate the possible effect of a probiotic mixture in the improvement of symptoms, the reduction in the number of days of hospitalization and the increase in the percentage of patients with negative PCR after infection with the coronavirus SARS-CoV-2.

Coagulopathy of COVID-19 afflicts approximately 20% of patients with severe COVID-19 and is associated with need for critical care and death. COVID-19 coagulopathy is characterized by elevated D-dimer, an indicator of fibrin formation and clot lysis, and a mildly prolonged prothrombin time, suggestive of coagulation consumption. To date, it seems that COVID-19 coagulopathy manifests with thromboembolism, thus anticoagulation may be of benefit. We propose to conduct a parallel pragmatic multi-centre open-label randomized controlled trial to determine the effect of therapeutic anticoagulation compared to standard care in hospitalized patients admitted for COVID-19 with an elevated D-dimer.

There is an urgent need to evaluate effective treatments for COVID-19 patients. Melatonin has significant anti-inflammatory and antioxidant properties and it lacks of side-effects. This randomized controlled trial seeks to evaluate the efficacy of intravenous melatonin in reducing mortality in Covid-19 patients in the ICUs.

The purpose of this study is to evaluate the efficacy of vadadustat for the prevention and treatment of acute respiratory distress syndrome (ARDS) in hospitalized patients with Coronavirus Disease 2019 (COVID-19).

Preliminary data support the effect of Nitric Oxide (NO) on improving the oxygenation in mechanically ventilated patients and spontaneously breathing patients with COVID-19. In vitro studies showed an antiviral effect of NO against SARS-coronavirus. The optimal therapeutic regimen of NO gas in spontaneously breathing hypoxemic patients with COVID-19 is not known. We hypothesize that high concentration inhaled NO with an adjunct of continuous low dose administration between the high concentration treatments can be safely administered in hypoxemic COVID-19 patients compared to the high dose treatment alone. Prolonged administration of NO gas may benefit the patients in terms of the severity of the clinical course and time to recovery. Together with a clinical effect on ventilation-perfusion matching, a prolonged regimen would allow also an increase in antiviral activity (dose and time-dependent).

Maraviroc (MVC) is a drug, very well tolerated, it has been seen that MVC has properties of modulating the immune system, exerting an anti-inflammatory effect in different diseases. In COVID-19, very high levels of inflammation occur that cause organs and systems to be damaged. MVC could reduce this inflammation achieving a better prognosis of COVID-19.
