Filter by:Brief Summary: SARS-CoV-2 virus infection is known to cause Lung Injury that begins as dyspnea and exercise intolerance, but may rapidly progress to Critical COVID-19 with Respiratory Failure and the need for noninvasive or mechanical ventilation. Mortality rates as high as 80% have been reported among those who require mechanical ventilation, despite best available intensive care. Patients with severe COVID-19 by FDA definition who have not developed respiratory failure be treated with nebulized ZYESAMI™ (aviptadil acetate, a synthetic version of Vasoactive Intestinal Polypeptide (VIP)) 100 μg 3x daily plus Standard of Care vs. placebo + Standard of Care using an FDA 501(k) cleared mesh nebulizer. The primary outcome will be progression in severity of COVID-19 (i.e. critical OR severe progressing to critical) over 28 days. Secondary outcomes will include blood oxygenation as measured by pulse oximetry, dyspnea, exercise tolerance, and levels of TNFα IL-6 and other cytokines.
The purpose of this study was to evaluate the efficacy of hydroxychloroquine (HCQ) and azithromycin (Azithro) to prevent hospitalization or death in symptomatic adult outpatients with COVID-19 caused by SARS-CoV-2 infection.
This is a randomized trial for the treatment of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection in high-risk adults not requiring hospital admission.The overarching goal of this study is to assess the effectiveness of interventions on the incidence of lower respiratory tract infection (LRTI) progression among high-risk adult outpatients with SARS-CoV-2 infection to inform public health control strategies.
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.
This is a prospective, multi-site study designed to evaluate whether the use of hydroxychloroquine in healthcare workers (HCW), Nursing Home Workers (NHW), first responders (FR), and Detroit Department of Transportation bus drivers (DDOT) in SE, Michigan, can prevent the acquisition, symptoms and clinical COVID-19 infection The primary objective of this study is to determine whether the use of daily or weekly oral hydroxychloroquine (HCQ) therapy will prevent SARS-CoV-2 infection and COVID-19 viremia and clinical COVID-19 infection healthcare workers (HCW) and first responders (FR) (EMS, Fire, Police, bus drivers) in Southeast Michigan. Preventing COVID-19 transmission to HCW, FR, and Detroit Department of Transportation (DDOT) bus drivers is a critical step in preserving the health care and first responder force, the prevention of COVID-19 transmission in health care facilities, with the potential to preserve thousands of lives in addition to sustaining health care systems and civil services both nationally and globally. If efficacious, further studies on the use of hydroxychloroquine to prevent COVID-19 in the general population could be undertaken, with a potential impact on hundreds of thousands of lives.
This is a three-arm randomized trial comparing the efficacy of single agent hydroxychloroquine to the combination of hydroxychloroquine and azithromycin, and to a delayed hydroxychloroquine regimen, which will serve as a contemporaneous Day 1-6 supportive care control, in eliminating detectable SARS-CoV-2 on day 6 following the initiation of treatment in order to determine which regimen is more effective.
Rationale: The current SARS-CoV-2 pandemic has a high burden of morbidity and mortality due to development of the so-called acute respiratory distress syndrome (ARDS). The renin-angiotensin-system (RAS) plays an important role in the development of ARDS. ACE2 is one of the enzymes involved in the RAS cascade. Virus spike protein binds to ACE2 to form a complex suitable for cellular internalization. The downregulation of ACE2 results in the excessive accumulation of angiotensin II, and it has been demonstrated that the stimulation of the angiotensin II type 1a receptor (AT1R) increases pulmonary vascular permeability, explaining the increased lung pathology when activity of ACE2 is decreased. Currently available AT1R blockers (ARBs) such as valsartan, have the potential to block this pathological process mediated by angiotensin II. There are presently two complementary mechanisms suggested: 1) ARBs block the excessive angiotensin-mediated AT1R activation, and 2) they upregulate ACE2, which reduces angiotensin II concentrations and increases the production of the protective vasodilator angiotensin 1-7. In light of the above, ARBs may prevent the development of ARDS and avert morbidity (admission to intensive care unit (ICU) and mechanical ventilation) and mortality. Objective: To investigate the effect of the ARB valsartan in comparison to placebo on the occurrence of one of the following items, within 14 days of randomization:1) ICU admission; 2) Mechanical ventilation; 3) Death. Study design: A double-blind, placebo-controlled 1:1 randomized clinical trial Study population: Adult hospitalized SARS-CoV-2-infected patients (n=651). Intervention: The active-treatment arm will receive valsartan in a dosage titrated to blood pressure up to a maximum of 160mg b.i.d. and the placebo arm will receive a matching placebo also titrated to blood pressure. Treatment duration will be 14 days or up to hospital discharge < 14 days or occurrence of the primary endpoint if < 14 days. Main study endpoint: The primary study endpoint is the occurrence within 14 days of randomization of either: 1) ICU admission; 2) Mechanical ventilation; 3) Death.
This is a pragmatic, randomized, open-label, incomplete factorial with nested randomization clinical trial evaluating the efficacy and safety of two potential treatments for hospitalized patients with confirmed SARS-CoV-2 infection. Participants who are hospitalized and have a positive nucleic acid amplification test for SARS-CoV-2 will undergo an initial randomization in a 1:1 ratio to one of the following regimens: Arm 1: Standard of care alone Arm 2: Standard of care plus hydroxychloroquine Participants who meet eligibility criteria to receive azithromycin will undergo a second randomization in a 1:1 ratio to receive additional concurrent therapy. This will effectively result in four treatment groups: 1. Standard of care alone 2. Standard of care plus hydroxychloroquine 3. Standard of care plus azithromycin 4. Standard of care plus hydroxychloroquine plus azithromycin
This individually randomized telemedicine-based trial aims to evaluate the efficacy of a single dose of azithromycin for prevention of progression of COVID-19 in patients with a recent positive SARS-CoV-2 test who are not currently hospitalized.
Hyper-inflammation, caused by a cytokine storm resulting from an exaggerated response of the immune system in the presence of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), is considered to represent one of the most important negative prognostic factors in patients infected with sSARS-CoV-2. The objective of this study is to investigate new treatment options to reduce the number of patients requiring mechanical ventilation. This is intended to address the most urgent need to preserve the access to intensive care unit support to the lowest possible number of patients and may potentially reduce mortality.
