Patients with COVID-19 frequently develop lower respiratory complications. Difficulty breathing and a low concentration of oxygen in the blood are of concern in patients with COVID-19, as they indicate that the lungs may be significantly affected. In some patients, respiratory symptoms may progress to the point where oxygen support is needed (i.e. use of an oxygen prongs, mask or ventilator). The exact mechanism of why patients with COVID-19 develop low concentrations of oxygen in blood is not fully understood. Some data suggest that the Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2), the virus causing Coronavirus Disease 2019 (COVID-19), can affect the body's blood vessels directly and extensively. In the lung, blood vessels participate in the absorption of oxygen. Endothelin is a potent hormone produced by human blood vessels. When increased, endothelin can result in the narrowing of blood vessels in the lung and decrease the volume of blood flowing through the lungs. This decrease in in blood flow through the lungs may be one of many factors affecting normal lung function. Ambrisentan can block the effects of endothelin in the body, and this could theoretically improve blood flow through the lungs. This study will evaluate whether ambrisentan, by blocking the effects of the hormone endothelin in the lungs, improves the breathing capacity of patients with COVID-19, increases the concentration of oxygen in the blood and prevents the progression to respiratory failure and death. Ambrisentan is a drug that is currently used to treat patients with pulmonary hypertension, a disease where blood flow through the lungs is decreased. Subjects participating in this study are those patients hospitalised with severe respiratory symptoms related to COVID-19, and are considered to be at high-risk of developing respiratory complications. Ambrisentan will be administered in the hospital, and will be continued at home for up to 28 days. In this study, ambrisentan will be administered at much lower doses that those used in patients with pulmonary hypertension.

The purpose of this study is to collect information that will help the reasearchers learn more about COVID-19 infections in cancer patients, and to find out about the effects of these infections on cancer treatment and outcomes. The research study involves asking people to complete a series of online questionnaires that include questions about their medical history, lifestyle, and risk factors related to the COVID-19 infection. The study will enroll both MSK patients and their household family members.

Efficacy and Safety of DWJ1248 with Remdesivir in Severe COVID-19 Patients

Objective: To determine whether NIV delivered through helmet interface reduces intubation rate among patients with COVID-19 ARDS compared to face-mask NIV and HFNC. Design, setting & participants: Two-center randomized clinical trial of 360 patients with mild to moderate ARDS and confirmed COVID-19 requiring non-invasive ventilation between August 2020 to January 2021. The patients with respiratory rate (RR) more than 30/min or oxygen saturation (SpO2) less than 90% or PaO2/FiO2 ratio less than 300 despite standard oxygen therapy by face mask (<15 L/min) who present to Royal hospital or Sultan Qaboos University Hospital (SQUH) emergency department, medical wards or intensive care unit (ICU). Intervention: Patients will be randomly assigned (block randomization) to either face-mask NIV, HFNC or Helmet NIV. The helmet is a transparent hood that covers the entire head of the patient and has a rubber collar neck seal. Main outcome and measures: The primary outcome is the rate of endotracheal intubation at 28-days. Secondary outcomes include hospital mortality at 28 and 90 days, NIV free days, invasive ventilator free days and hospital length of stay. Expected results: We assume the failure rate of Helmet NIV to be 30%, failure rate of HFNC to be 40% and failure rate of face-mask NIV to be 50%. A sample size of 360 patients (120/group) will achieve a power of 0.90 at a significance level of 0.05. To account for 10% dropout rate, the total sample required is 396 subjects(132/group).

COVID-19 is a respiratory disease caused by a novel coronavirus (SARS-CoV-2) and causes substantial morbidity and mortality. Nosocomial acquisition of SARS-CoV-2 is a frequent concern across hospital settings in Canada and is associated with substantial morbidity and mortality. This clinical trial is initially designed to evaluate the role of monoclonal antibodies against the SARS-CoV-2 spike protein, for the treatment of hospitalized patients who acquire COVID19 via nosocomial infection. New treatments, as they become available, may be integrated, with appropriate adaptation of this document. The trial was initiated with the bamlanivimab product with the options of casirivimab/imdesimab and sotrovimab added as the prevalence of bamlanivimab resistant variants of concerns increased. It is believed that monoclonal antibody treatments are most likely to be effective early in the disease course. The ability to rapidly identify and initiate such treatments in patients with nosocomial acquisition of the infection, combined with the high mortality of 25-30% experienced by this group of patients led us to propose this trial in collaboration with the CATCO national network. The overall objective of the study is to evaluate the safety and clinical effectiveness of anti-SARS-CoV-2 monoclonal antibody treatment relative to the control arm, in patients who develop nosocomial SARS-CoV-2 infection, on need for mechanical ventilation or death. This study is designed as a pragmatic randomized, open-label, controlled clinical trial. Subjects will be randomized to receive either standard-of-care (control) or the study medication on a 1:2 basis. Bamlanivimab, casirivimab/imdesimab or sotrovimab will be administered intravenously as a one-time infusion after randomization. Casirivimab/imdesimab (REGN) and sotrovimab will be the default agents based on local availability unless both are unavailable AND virus strain known to be native or alpha (B.1.1.7). Incidence of infusion-related reactions in the 24 hours post administration.

A novel corona virus emerged in 2019 causing Corona Virus Disease 2019 (covid-19). In one year more than 80 000 000 cases worldwide were documented. Some patients experience symptoms, specifically shortness of breath, long after the viral infection has passed. These patients are colloquially known as "Covid-19 Long-Haulers" and it is currently unknown why symptoms remain after infection. Shortness of breath and exercise intolerance may be caused by corona virus infection, covid-19 therapy, and reduced physical activity. Exercise intolerance may be due to lung, heart, blood vessel and muscle changes. During infection, the corona virus appears to cause lung blood vessel and gas exchange surface damage. Early reports show heart dysfunction, secondary to pulmonary blood vessel dysfunction or damage. Critically, no data is available on lung blood vessel function or cardiac function during exercise. Moreover, no data are available to link persistent symptoms to physiology parameters. To better understand symptom persistence in Covid-19, the investigators aim to measure exercise tolerance and heart and lung function in covid-19 survivors and compare them to covid-19 free controls.

There are several ways in which the COVID-19 pandemic may affect the prevention and management of thrombotic and thromboembolic disease, either direct effect or the indirect effects of infection, such as through severe illness and hypoxia, may predispose patients to thrombotic events. The severe inflammatory response, critical illness, and underlying traditional risk factors may all predispose to thrombotic events. Therefore, considering the high-risk profile of cardiovascular comorbidities in patients with COVID-19, it is scientifically relevant to evaluate the use of anticoagulants as an adjunctive treatment in the context of COVID-19. Indeed, it will be tested the hypothesis that the use of moderate dose of rivaroxaban has a beneficial effect in the treatment of patients with a confirmed or probable diagnosis of COVID-19 infection, with no clear indication for hospitalization (mild and moderate cases) upon initial medical care, by reducing the need of hospitalization due to complications related to COVID-19.

This is a prospective single-center study for the follow-up of SARS-CoV-2 positive patients in the district of Konstanz (LKN). As part of the coronavirus pandemic, patients with SARS-CoV-2 infection are currently being treated in the clinics of the LKN's health network at the Singen (Hegau-Bodensee Clinic) and Konstanz (Konstanz Clinic) locations. So far, there is little data on the long-term effects of SARS-CoV-2 infection. As part of this study, the disease progression of these patients will be monitored. Study objective: Prospective, controlled follow-up observation of SARS-CoV-2 positive patients regarding their secondary diseases and quality of life.
