Active clinical trials for "COVID-19"

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).

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.

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.

The purpose of this study is to determine if treatment with convalescent plasma improves the clinical outcomes of Veterans who are hospitalized and require supplemental oxygen due to COVID-19.

The purpose of this trial is to assess the safety and toxicity profile of the combination of famotidine and oral n-acetyl cysteine in adult outpatients with newly diagnosed SARS-CoV-2 infection.

The overall objective of the study is to determine the therapeutic effect and tolerance of Camostat mesylate, compared to placebo in adult patients with ambulatory COVID-19 disease, presenting with risk factors of severe COVID-19. Camostat mesylate is a serine protease TMPRSS2 (Transmembrane Serine Protease 2) inhibitor which has been successfully and safely used to treat pancreatitis-associated pain and post-operative reflux oesophagitis in Japan. More recently, it has been shown to inhibit SARS-CoV-2 viral entry and reduce infection of human primary pneumocytes and lung cell lines. Camostat mesylate or placebo will be administered to consenting adult patients with virologically confirmed COVID-19, not requiring initial hospitalization. All patients will receive standard of care along with randomized treatments. Outcomes of included patients will be compared between the 2 groups.

This study is a combined Phase 1 and Phase 2 study with IV infusion of NGM621 to evaluate the safety, tolerability, and PK in healthy volunteers (Part 1), and safety, tolerability, PK and efficacy in subjects with confirmed SARS-CoV-2 infection (Part 2).

A) Phase II: Early viral responses to triazavirin In hospitalised patients with mild-moderate COVID-19, in addition to standard of care therapy, treatment with triazavirin 250mg three times daily for five days, the slope of increase of the Ct values of serial nasopharyngeal swabs to 12 days after initiation of treatment will be ≥24% higher than in hospitalised patients receiving standard of care treatment only. B) Phase III: Efficacy of triazavirin to improve clinical outcomes In hospitalised patients with mild-moderate laboratory proven COVID-19, in addition to standard of care therapy, treatment with triazavirin 250mg three times daily for five days will reduce a composite outcome - death; ICU admission or mechanical ventilation; or prolonged duration of admission- by ≥29% when compared to the composite outcome in hospitalised patients receiving standard of care therapy only.

This study is a multi-center, randomized, double blinded, prospective, placebo controlled study. Patients upon diagnosis of COVID-19 (Corona Virus Disease-19) will be eligible to participate in the study. The purpose of this study is to find out the side effects and ability to take the study drug, Nitric Oxide (NO) lozenges when taken twice daily by mouth. If this study shows that the drug has no or few, acceptable side effects, it will then include up to 840 participants to find out if the drug can reduce bad outcomes of COVID-19 infection (hospitalization, ICU admission, death). In each part of the study, half of the subjects will receive the study drug and the other half will be given a placebo (inactive pill).

This study aims to examine the association between gut microbiota composition and the magnitude and duration of immune response in subjects who have received different COVID-19 vaccines in Hong Kong and to identify the differences compared to those COVID-19 recovered subjects.
