COVID-19 Clinical Trials and Expanded Access

The purpose of this research study is to determine if high-frequency, rapid turn-around SARS-CoV-2 surveillance testing with this assay is feasible and able to be optimized to enable isolation and follow-up diagnostic testing. This test will be performed at various locations in the Madison, Wisconsin area using a mobile laboratory or standard lab space for processing. Saliva samples can be collected and processed at these locations or participants can self-collect at home and drop their samples off at designated locations for same day processing. Up to 10000 participants will be recruited for this study.

This study is designed as a multicenter, randomized, double-blind, placebo-controlled clinical trial to evaluate the clinical efficacy and safety of MW33 injection in patients with mild or moderate COVID-19, and to evaluate its pharmacokinetic profile and immunogenicity.

Project is designed as a comprehensive population-based epidemiological study in Upper-Silesian Conurbation (Poland) aiming at: 1. analysis of available data on incidence and mortality due to COVID-19 and 2. estimation of the occurrence of viral infection SARS-CoV-2 as revealed by the results of serological test (ELISA: IgM, IgG), with assessment of risk factors. The project's objectives are: to assess incidence and mortality due COVID-19 according to sex, age and coexisting diseases; to determine the level of potential "underdiagnosis" of the magnitude of COVID-19 mortality using vital statistics data for Upper-Silesian Conurbation; to assess the prevalence of SARS-CoV-2 based on the level of seropositivity in Upper-Silesian Conurbation; to identify host-related and environmental risk factors if the infection. Analysis of existing data will include monthly records on incidence and mortality over the period 01.01.2020-31.12.2020 and comparison of the findings with the monthly records of 2018 and 2019, for the same population. Cross-sectional epidemiological study will be located in three towne (Katowice, Sosnowiec, Gliwice). In each town a representative age-stratified sample of 2000 subjects will undergo questionnaire assessment and serological examination performed by serological test. The project corresponds with analogous population-based studies on COVID-19 in a number of countries and responds to the WHO recommendation in that field.

The aim of this study is to assess the epidemiological and clinical features of patients diagnosed with COVID-19 in Kazakhstan at the onset of the pandemic.

It is known that vitamin D has been found to decrease incidence of viral respiratory infections, as well as have effects on multiple cytokines involved in immunomodulation and the bradykinin/renin-angiotensin system. Recently, data was released showing a correlation between baseline vitamin D deficiency status and increased risk of contracting COVID-19. Separate analysis shows that many of the deleterious effects of COVID-19 may be due to the bradykinin/RAS system, and that vitamin D is one plausible treatment option to modulate these effects. Studies are currently ongoing to determine if vitamin D supplementation of those hospitalized with COVID-19 has a beneficial effect on patient outcomes. Healthcare resources have been strained during the pandemic in areas of heavy caseload. It is possible that those with concurrent vitamin D deficiency and COVID positivity have an increased need for escalation of care. A small study has been conducted in this area, but was limited by small number of subjects.

The purpose of this study is to evaluate the efficacy and safety of the metformin glycinate and standard treatment of the hospital in hospitalized patients with Severe Acute Respiratory Syndrome secondary to SARS-CoV2.

On 30 January 2020, WHO declared the SARS-CoV-2 outbreak as a public health emergency of international concern. Compared to SARS-CoV, which caused an outbreak of SARS in 2003, SARS-CoV-2 has a higher transmission capacity. Although the clinical manifestations of SARS-CoV-2 are dominated by respiratory symptoms, some patients have severe cardiovascular damage. In addition, patients with underlying cardiovascular disease may be at increased risk of death. Therefore, understanding the impairments caused by SARS-CoV-2 to the cardiovascular system and the underlying mechanisms is of the utmost importance. Circulating endothelial cells (CECs) are generally considered markers of lesions and may be non-invasive markers of pulmonary vascular dysfunction during SARS-CoV-2 infection. Another marker of endothelial activation could be circulating extracellular vesicles. They could also be involved in the spread of the virus. Thus this project proposes to study different aspects of the diagnosis and pathophysiology of SARS-CoV-2. We propose to fully study activation state of coagulation and endothelium on a plasma and cellular side in patients diagnosed with SARS-CoV-2/COVID19. The different forms of the disease will be included: without lung disease, with a more or less severe lung disease, i.e. having evolved or not towards acute respiratory distress syndrome (ARDS). Extensive research of biomarkers will be compared to the detection of the virus in the respiratory tract as well as in the blood. This work will contribute to a better description of disease pathophysiology and should allow us to identify a patient profile in whom preventive or curative anticoagulant therapy could be considered.

The purpose of this study is to evaluate the efficacy and safety of metformin glycinate at dose of 620 mg twice per day plus standard treatment comparing to standard treatment alone (we will use placebo) of patients who have metabolic syndrome or type 2 diabetes, which have severe acute respiratory syndrome secondary to SARS-CoV-2.

The International Registry of Healthcare Workers Exposed to COVID-19 Patients (UNITY Global), is an international registry of approximately 10,000 healthcare workers in low- and middle-income countries experiencing increasing numbers of COVID-19 cases and commensurate increased exposure to the SARS-CoV-2 virus among their healthcare worker populations.
