Active clinical trials for "Coronavirus Infections"

CCAP is an investigator-initiated multicentre, randomized, double blinded, placebo-controlled trial, which aims to assess the safety and efficacy of treatment with convalescent plasma for patients with moderate-severe COVID-19. Participants will be randomized 2:1 to two parallel treatment arms: Convalescent plasma, and intravenous placebo. Primary outcome is a composite endpoint of all-cause mortality or need of invasive mechanical ventilation up to 28 days.

Double blinded randomized clinical trial designed to evaluate the efficacy and safety of hydroxychloroquine combined with azithromycin compared to hydroxychloroquine monotherapy in patients hospitalized with confirmed COVID-19 pneumonia.

Study Objective: To test if early preemptive hydroxychloroquine therapy can prevent disease progression in persons with known symptomatic COVID-19 disease, decreasing hospitalizations and symptom severity.

This study aims to address the following objectives: To determine the efficacy of IC14, an anti-CD14 chimeric monoclonal antibody, in patients hospitalized with respiratory disease and hypoxemia due to SARS-CoV-2, in terms of improving the time to resolution of disease. To determine the efficacy of IC14 in reducing the severity of respiratory disease in patients hospitalized with respiratory disease due to SARS-CoV-2. To determine the safety of IC14 in patients hospitalized with respiratory disease due to SARS-CoV-2.

There is surge in COVID infected patients in New York City with a shortage of hospital beds, ICU beds and ventilators. Strategies to reduce the need for all of the above are immediately needed. Further, few interventions are targeted in COVID infected patients early in the course of their disease and especially in the community/home settings. Respiratory decompensation appears to occur later in the disease process (i.e. 7-10 days after becoming symptomatic) therefore many patients are sent home from the Emergency Room and they subsequently decompensate later at home. Some patients die at home and others are returning to the Emergency Room with hypoxemic respiratory failure. There is no treatment offered to this population of patients, i.e. COVID suspected or confirmed and with respiratory symptoms or abnormal chest x-ray at the time of presentation. Based on experience across the globe, these patients are likely to worsen at home. The study team therefore proposes a prospective, single-center, parallel group, open-label, randomized clinical trial to assess the efficacy of fixed low continuous positive airway pressure therapy (CPAP) (FDA approved and often used for treatment of sleep apnea) in COVID confirmed or suspected patients with abnormal chest x-ray or respiratory symptoms who do not require hospital admission and are discharged home from the emergency room.

Base on Arbidol antiviral therapy,the investigators conduct a randomized, open-label trial to evaluate and compare the safety and efficacy of ASC09 /ritonavir and lopinavir/ritonavir in patients with 2019-nCoV pneumonia.

The 2019 outbreak of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2 or COVID 19), which originated in Wuhan, China, has become a major concern all over the world. Convalescent plasma or immunoglobulins have been used as a last resort to improve the survival rate of patients with SARS whose condition continued to deteriorate despite any attempted treatment.. Moreover, several studies showed a shorter hospital stay and lower mortality in patients treated with convalescent plasma than those who were not treated with convalescent plasma. Evidence shows that convalescent plasma from patients who have recovered from viral infections can be used effectively as a treatment of patients with active disease. The use of solutions enriched of antiviral antibodies has several important advantages over the convalescent plasma including the high level of neutralizing antibodies supplied. Plasma-exchange is expensive and requires large volumes of substitution fluid. Albumin is better tolerated and less expensive, but exchanges using albumin solutions increase the risk of bleeding because of progressive coagulation factor depletion. With either albumin or fresh frozen plasma, increasing the risk of cardiovascular instability in the plasma donor and in the recipient, which can be detrimental in a critically ill patient with COVID 19 pneumonia. The aforementioned limitations of plasma therapy can be overcome by using selective apheresis methods, such as double-filtration plasmapheresis (DFPP).DFPP is a modality of plasma purification that performs an initial plasma separation from blood, and the subsequent separation of specific molecules, on the basis of their specific molecular weight (cut-off), by using a fractionation filter. The Fractionation Filter 2A20, because of its membrane sieving cut-off, retains larger molecules and returns plasma along with smaller molecules to the circulation, including the major part of the albumin. The selection of the membrane 2A20 is related to the appropriate Sieving Coefficient for IgG that allows to efficiently collect antibodies from patients which are recovered from COVID-19, with negligible fluid losses and limited removal of albumin. The total amount of antibodies obtained during one DFPP session exceeds by three to four times the total amount provided to recipients with one unit of plasma obtained during one plasma-exchange session from one COVID-19 convalescent donor. This should result in more effective viral inhibition and larger benefit for the patient achieved with one unit of enriched immunoglobulin solution obtained with DFPP than with one unit of plasma obtained with plasma exchange. These observations provide the background for a pilot study aimed to explore whether the infusion of antibodies obtained with one single DFPP procedure from voluntary convalescent donors could offer an effective and safe therapeutic option for critically ill patients with severe coronavirus (COVID-19) pneumonia requiring mechanical ventilation.

To create a protocol for treatment of Pakistani patients with SARS-CoV-2 infection with an intent to reduce burden on institutional healthcare services by determining efficacy of different quinone drug dosing regimens in controlling SARS-CoV-2 infection for asymptomatic patients.

There is an urgent need to evaluate interventions that could be effective against the infection with SARS-CoV 2. Tannins based wood extracts are an inexpensive and safe product with protective effect in both bacterial and viral infections likely due to its anti- inflammatory, anti-oxidative effects and their modulation of the intestinal microbiota. This randomized controlled trial seeks to evaluate the efficacy of the tannins based dietary supplement ARBOX in positive COVID-19 patients.

Prospective nationwide cohort study of pregnant women enrolled early in gestation and followed for Covid-19 exposure and infection, with follow up of obstetrical outcomes and infant development through the first year of life.
