The current COVID-19 pandemic is a worldwide healthcare crisis. Of concern is the large number of patients that are/will require mechanical ventilation, and the associated strain that this will place on healthcare resources. At present, there are no specific therapeutic interventions directed at COVID-19 infection. However, observational data suggest that there is a subgroup of patients that demonstrate a hyperinflammatory response in response to COVID-19 and have a higher requirement for Critical Care and higher mortality. There is a strong case for the use of the naturally occurring anti-inflammatory cytokine interleukin-1 receptor antagonist (IL-1Ra) in these patients. Anakinra is a recombinant form of IL-1Ra that is licensed for clinical use. Success of use of anakinra in COVID-19 trials will be greatly enhanced by robust scientific evidence and established pharmacokinetics which inform the most effective dosing regimens. The latter is especially important when, as in the case of anakinra, drug supplies are limited, the drug has short half-life and clinical ease of application is critical.
Background: Coronavirus disease 2019 (COVID-19) is an acute respiratory syndrome. It is caused by the SARS-CoV-2 virus. People with severe COVID-19 infection have a hyper-inflammatory response. Bruton tyrosine kinase (BTK) plays a role in the innate immune system. BTK inhibition can be used to target the innate immune system that appears to contribute to mortality. This could be an effective way to help the inflammatory responses in people with COVID-19. Objective: To learn more about the immunologic mechanisms by which BTK inhibition may decrease hyper-inflammatory responses in people with COVID-19. Eligibility: People ages 18 and older in one of the following groups: - They are in the hospital with COVID-19. They will or will not be treated with a BTK inhibitor. - They do not have COVID-19. They are or are not in the hospital. They will be treated with a BTK inhibitor for a reason other than COVID-19. Design: Participants will be screened with a review of their demographic and clinical information. Their medical history will be reviewed. If they have COVID-19, their symptoms will be assessed. Participants will give 3-4 blood samples. These may be taken through a vein. They may also be taken through an existing central venous catheter. Participants may give a stool sample. This will be collected by nursing staff. It will be collected using a stool collection vial. Stool collection is optional. Participants samples will be collected over about 7 days. These will be used for research and genetic testing.
Treatments for COVID-19 are urgently needed. Hydroxychloroquine (HCQ) is an antimalarial and immunomodulatory agent being repurposed for COVID-19 therapy based off in vitro data suggesting a possible antiviral effect. However, HCQ's effect on COVID-19 in human infection remains unknown. To fill this knowledge gap, we will enroll 626 adult patients hospitalized with laboratory-confirmed COVID-19 and randomize them 1:1 to a five-day course of HCQ or placebo. Notable exclusion criteria include ICU admission or ventilation on enrollment, prior therapy with HCQ, and baseline prolonged qTC. Our primary endpoint is a severe disease progression composite outcome (death, ICU admission, mechanical ventilation, ECMO, , and/or vasopressor requirement) at the 14-day post-treatment evaluation. Notable secondary clinical outcomes include 30-day mortality, hospital length of stay, noninvasive ventilator support, and cytokine release syndrome (CRS) grading scale. Secondary exploratory objectives will examine SARS-CoV-2 viral eradication at the EOT, changes in COVID-19 putative prognostic markers and cytokine levels, and titers of anti-SARS-CoV-2 antibodies. This randomized trial will determine if HCQ is effective as treatment in hospitalized non-ICU patients with COVID-19.
We propose a 3-arm RCT to determine the efficacy of hydroxychloroquine or azithromycin in treating mild to moderate COVID-19 among Veterans in the outpatient setting.
This is an exploratory study to evaluate the efficacy of hydroxychloroquine (400 mg BID on D1 and 400 mg/day on D2 to D7) and azithromycin (500 mg/ 5 days) to treat mild ambulatory COVID-19 patients.
This study will assess the efficacy of hydroxychloroquine in reducing the severity of symptoms in patients with COVID-19
Coronavirus disease 2019 (COVID-19) is a pandemic infection caused by a virus called severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). Because SARS-CoV-2 is known to require the angiotensin-converting enzyme 2 (ACE-2) receptor for uptake into the human body, there have been questions about whether medications that upregulate ACE-2 receptors might increase the risk of infection and subsequent complications. One such group of medications are anti-hypertensives that block the renin-angiotensin system, including both angiotensin converting enzyme inhibitors (ACEi) and angiotensin II receptor blockers (ARB). Both ACEi and ARB are widely used for the treatment of hypertension. Early reports from China and Italy suggest that many of those who die from COVID-19 have a coexisting history of hypertension. Consequently, there have been questions raised as to whether these 2 types of blood pressure medication might increase the risk of death among patients with COVID-19. However, it is well known that the prevalence of hypertension increases linearly with age. Therefore, it is possible that the high prevalence of hypertension and ACEi/ARB use among persons who die from COVID-19 is simply confounded by age (older people are at risk of both a history of hypertension and dying from COVID-19). Whether these commonly prescribed blood pressure medications increase the risk of COVID-19 or not remains unanswered. Statements from professional cardiology societies on both sides of the Atlantic have called for urgent research into this question. Our study aims to randomize patients with primary (essential) hypertension who are already taking ACEi/ARB to either switch to an alternative BP medication or continue with the ACEi/ARB that they have already been prescribed. Adults with compelling indications for ACEi/ARB will not be enrolled.
This is an exploratory study to evaluate the efficacy of hydroxychloroquine (400 mg BID on D1 and 400 mg/day on D2 to D5) and azithromycin (500 mg/ 5 days) to treat moderate to severe COVID-19 pneumonia.
In December 2019, Wuhan, in Hubei province, China, became the center of an outbreak of pneumonia caused by CoVID-19, and the number of cases of infection with CoVID-19 identified in Wuhan increased markedly over the later part of January 2020, with cases identified in multiple other Provinces of China and internationally.Given no specific antiviral therapy for CoVID-19 infection and the availability of Yinhu Qingwen Granula as a potential antiviral Chinese medicine based on vivo antiviral studies in CoVID-19, this adaptive, randomized,double-blind,controlled trial will evaluate the efficacy and safety of Yinhu Qingwen Granula in patients hospitalized with severe CoVID-19.
