Active clinical trials for "Coronavirus Infections"

COVID-19 may cause another world-wide epidemic. This study is divided into 2 arms: (1) Prospective longitudinal observational study involving patients with laboratory-confirmed COVID-19 and (2) Retrospective study on patients with laboratory-confirmed COVID-19. Arm 1: We will collect EDTA blood, stool samples, rectal swab, urine, saliva, and specimens from upper respiratory tract (nasopharyngeal aspirate or flocked swab), and lower respiratory tract (sputum or tracheal aspirate) on daily, alternate day, or weekly basis as appropriate. Arm 2: The remainder of specimens that were submitted for laboratory investigation as part of clinical management will be retrieved. Those specimens will only be used after all clinically indicated testing and confirmation procedures have been completed. Assistance from the Public Health Laboratory Service, Department of Health, will be invited to retrieve samples as well as participate in this study. Patients hospitalized for pneumonia in medical wards and ICU at the Prince of Wales Hospital tested negative for COVID-19 will be recruited as controls. Understanding the clinical, virological, microbiological and immunological profiles of this infection is urgently needed to facilitate its management and control.

This study seeks to determine whether the virus which causes COVID-19, SARS-CoV-2, is shed in the stools of patients who are infected.

At the time of writing (3/4/2020), close to a million people have been infected by the SARS-CoV-2 coronavirus around the world. The severe clinical condition that leads to deaths is now called CoVID-19. Currently, there are no effective treatments for the early or late stages of this illness. Governments worldwide have undertaken dramatic interventions to try and reduce the rate of spread of this deadly coronavirus. Early data from multiple studies in China, where the virus originated, show that severe cases of CoVID-19 are not as prevalent in patients with chronic lung diseases as expected. This data has been confirmed by the Italian physicians. The investigators think that the widespread use of inhaled corticosteroids reduces the risk of CoVID-19 pneumonia in patients with chronic lung disease. Early microbiological data also shows that these corticosteroids are effective at slowing down the rate of coronavirus replication on lung cells. Inhaled corticosteroids are widely used to manage common lung conditions, such as asthma. This type of medicine is among the top 3 most common medication prescribed around the world. Their safety is well understood, and their potential side effects are mild and reversible. The investigators propose to test this idea that, in participants early in the course of CoVID-19 illness, daily high dose inhaled corticosteroids for 28 days, will reduce the chances of severe respiratory illness needing hospitalisation. We will also study the effect of this inhaled therapy on symptoms and viral load.

Non tuberculous mycobacteria (NTM), Burkholdria spp, Aspergillus in the lung are almost impossible to eradicate with conventional antibiotics. In addition COVID-19 has know current treatment. These patients have few options to treat their lung infection. Nitric oxide has broad bactericidal and virucidal properties. It has been shown that nitric oxide was safe to be inhaled for similar cystic fibrosis patients and reduced drug resistant bacteria in the lungs. Further, research indicates that clinical isolates of NTM, Burkholderia spp, Aspergillus spp and Corona-like viruses can be eradicated by 160ppm NO exposure in the laboratory petri dish. This is not the first time inhaled NO treatment has been used in patients with difficult lung infections. This study will provide more data to see if NO therapy can reduce the bacterial load in the lungs, help the patients breath better; and in the case of COVID-19 act as a anti-viral agent resulting in the reduction of incidence of oxygen therapy, mechanical assistance of BIPAP, CPAP, intubation and mechanical ventilation during the study period.

The Severe Acute Respiratory Syndrome COronaVirus 2 (SARS-CoV2) is a new and recognized infectious disease of the respiratory tract. Most cases are mild or asymptomatic. However, around 5% of all patients develop Acute Respiratory Distress Syndrome (ARDS), which is the leading mortality cause in these patients. Corticosteroids have been tested in deferent scenarios of ARDS, including viral pneumonia, and the early use of dexamethasone is safe and appears to reduce the duration of mechanical ventilation in ARDS patients. Nevertheless, no large, randomized, controlled trial was performed evaluating the role of corticosteroids in patients with ARDS due SARS-CoV2 virus. Therefore, the present study will evaluate the effectiveness of dexamethasone compared to control (no corticosteroids) in patients with moderate and severe ARDS due to SARS-CoV2 virus.

This is a phase 3, randomized, double-blind, placebo-controlled multicenter study to evaluate the efficacy and safety of colchicine in adult patients diagnosed with COVID-19 infection and have at least one high-risk criterion. Approximately 6000 subjects meeting all inclusion and no exclusion criteria will be randomized to receive either colchicine or placebo tablets for 30 days.

Coronaviruses (CoV) are positive-sense single-stranded RNA viruses that infect a wide range of hosts producing diseases ranging from the common cold to serious / fatal events. Nitazoxanide (NTZx) is a derivative of 5-nitrothiazole, synthesized in 1974 by Rosignol - Cavier. NTZx has powerful antiviral effects through the phosphorylation of protein kinase activated by double-stranded RNA, which leads to an increase in phosphorylated factor 2-alpha, an intracellular protein with antiviral effects. The purpose of this study is to contrast the beneficial effect of NTZx vs NTZx plus hydroxychloroquine in patients Coronavirus Disease (COVID-19) as well as against other treatments.

This was a randomized, double-blind, placebo-controlled, 29-day study to assess the efficacy and safety of axatilimab plus standard of care (SOC), compared with placebo plus SOC, in participants with respiratory signs and symptoms secondary to COVID-19.

Plasma exchanges with 5% human albumin (2/3 of the exchanged plasma volume) and fresh frozen plasma (FFP: 1/3) in patients with quick <50% or only with 5% albumin in patients with quick of 50% or more. We will exchange between 1.2 and 1.5 plasma volumes, that will vary according to sex, weight, height and hematocrit.

COVID-19 is a disease with high rate of morbidity if symptomatic. There is a great need of treatments to decrease the severity. The vast majority of patients needing intensive care are men, and this may be due to the androgens, either by regulation of TMPRSS2, necessary for virus internalization, or other mechanisms. Enzalutamide is an antiandrogen inhibiting the expression of androgen regulated proteins, such as TMPRSS2. The aim of this trial is to evaluate a possible beneficial effect of short-term enzalutamide treatment of COVID-19 patients.
