Clinical Trials and Expanded Access

During the COVID-19 pandemic several countries have seen a high risk of transmission for health care personnel, with some countries having as many 20-25% of nurses and doctors either infected or showing symptoms of COVID-19. In this prospective cohort study, we will systematically screen all hospital staff in the Capital Region of Denmark for IgM and IgG antibodies against SARS-CoV-2 using a point of care tests and an Elisa kit. Testing will be offered 3 times: In April 2020, Maj 2020 and September 2020. All participants will submit a questionnaire regarding exposures, risk factors and symptoms of COVID-19 in relation to each testing. Follow-up will be through electronic patient records and national registries. We will compare the group of health care personnel with data from a control group of healthy volunteer blood donors from the Danish Blood Donor Study. The aim of the study is to investigate the proportion of hospital staff with SARS-CoV-2 antibodies during the study period compared to a control group representing the Danish population. We will compare the test characteristics of the two methods of testing, a point of care test and Elisa. Further, we will investigate the extent to which prior immunization or infection is protective for future infection with COVID-19.

Summary of the study Study population: A representative sample of the Viennese population stratified by age and gender (data from the Vienna Health Study LEAD) Potential output and analysis: - Extent of age-specific infection and antibody formation - Cumulative incidence of infection - Rate of asymptomatic infection - Relationship with socioeconomics, lifestyle and risk factors (comorbidities) Study design: Prospective, longitudinal, stratified by age and gender Duration of study: Initial testing as soon as possible and repeat based on monitoring of the pandemic curve (probably after 2-3 months) Information to be obtained from participants: - serum samples for information on SARS-CoV2 infection and antibody formation - data on clinical symptoms

Doctors, nurses and staff members of ear-nose and throat (ENT) departments are at high risk due to aerosol-inducing diagnostic procedures and surgery during the COVID-19 epidemic. Reports from China, Spain, Italy and England report of fatal cases among ENT specialists. With a concurrent lack of personal protection, it is of paramount importance to identify patients and healthcare workers at an early stage to prevent a COVID-19 outbreak in the department. A baseline study of all healthcare workers has been performed. Follow-up will be accomplished by interval testing, antibody measurements and REDcap Covid-19 questionnaires. All patients at risk of carrying SARS-CoV-2, or who are candidates for high-risk airway surgery will be tested. Infection control measures at the department will be implemented progressively according to the real-time surveillance results from both patients and healthcare workers.

The purpose of this research is to collect information about coronavirus exposures, symptoms, and health care visits due to the among Atrium Health clients and health care workers. Participation in this study will involve completing a daily questionnaire which covers participants coronavirus illness history or symptoms, health care seeking behaviors and treatments, contact with other sick people, and for health care workers, their use of personal protective equipment.

Purpose: To determine the number of asymptomatic individuals who have antibodies to SARS-CoV-2, the virus which causes COVID-19

This study seeks to investigate the role of lung ultrasound in caring for Covid-19 positive patients and whether it can be used to predict patient deterioration. This information will be vital for healthcare workers who seek to identify Covid-19 pneumonia or patients at risk for deterioration early in the disease course.

This study will study the potential utility of the Quantra QPlus System in patients inflicted with COVID-19 disease.

Healthcare workers play a critical role in fighting the pandemic, not only by managing the patients' health clinically, but also by implementing adequate measures for infection prevention and control in healthcare facilities. This puts healthcare workers at a greater risk of acquiring the disease. COVID-19 is caused by Severe Acute Respiratory Syndrome Coronavirus -2 (SARS-CoV-2) and many people can be infected with it asymptomatically and undetectably. Serology is an antibody test that provides additional information to polymerase chain-reaction (PCR) testing as it is the only way to reliably establish the fraction of the population that was infected . Seroconversion is the development of antibodies in the blood which can confirm suspected cases after the fact and reveal who was infected but asymptomatic and never realized it. Antibodies are specific proteins created as the body's response to the infection and this test is essential for detecting infected individuals with few or no symptoms at all.

Infection with covid-19 is associated with respiratory failure, which when related to other etiologies can lead to reduced quality of life, physical, cognitive and mental dysfunction. There is no knowledge of the possible consequences of severe covid-19 infection. Our objective is to describe these repercussions, identifying risk factors and assessing the impact of physical training. At least 100 patients over 18 years of age who survive severe Covid-19 infection will be evaluated. Assessments after 1, 4, 6 and 12 months after hospital discharge. Quality of life, dyspnea, activity of daily living, muscle strength, mental and cognitive dysfunction will be evaluated, as well as pulmonary function test, cardiopulmonary stress test and chest tomography. Return to work, thromboembolic events and mortality up to 12 months will also be monitored. Hospitalization data will be used to identify factors related to quality of life, fatigue and respiratory dysfunction. Predefined risk factors will be evaluated: age, sex, smoking, previous comorbidities index, previous clinical frailty, serum C-reactive protein and leukocyte / lymphocyte ratio in the first 24 hours of hospitalization, time between onset of symptoms and hospitalization, ICU and mechanical ventilation, time on mechanical ventilation, compliance corrected by the ideal weight at the start of mechanical ventilation, driving pressure, tidal volume corrected by the ideal weight and PEEP (positive end expiratory pressure) after 24 hours of intubation in controlled ventilation, tidal volume corrected by the ideal weight after 24 hours of spontaneous ventilation, inspiratory muscle training and pulmonary rehabilitation after hospital discharge.

"This is a prospective, single-center specimen collection study. Subjects 18 years of age or older who do not have symptoms of COVID-19 will be enrolled. Two nasal swab samples and one saliva sample will be collected from each subject. The saliva sample will be tested with the COVIDSeq Test and one nasal swab will be tested with an EUA approved COVID test. The other nasal swab sample will be stored and a subset (approximately 250 specimens) will be tested with the COVIDSeq Test. Results of all testing will be provided to the sponsor for statistical analysis. Results from the comparator EUA test will be provided to the collection site investigator or designated collection site study staff. No medical treatment, guidance on treatment decisions, nor medical care will be provided. "
