COVID-19 Clinical Trials and Expanded Access

Evaluation of the agreement between fingerstick samples, venous blood, serum and plasmasamples when using the LumiraDx SARS-CoV-2 Ab Test against the reference method, usingstandard qualitative comparison techniques.

Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is the cause of atypicalemerging pneumonia. The clinical spectrum varies from an asymptomatic or mild illness toa serious illness with a high risk of mortality. The most severely affected patients (5%)present an acute respiratory distress syndrome (ARDS), requiring assistance withmechanical ventilation in intensive care.In 2003, persistent lung damage was observed in a third of patients in a Singaporeancohort one year after SARS-CoV infection. A Chinese study showed that 27.3% of theirSARS-CoV patients presented a decreased carbon monoxide diffusion (DLCO) and 21.5% ofpulmonary fibrosis lesions.Due to the very recent emergence of SARS-CoV-2, no data is currently available oflong-term outcome of these patients. However, recent publications including short-term CTmonitoring suggest the genesis of fibrotic pulmonary parenchymal sequelae.In view of these data, the investigators can fear the occurrence of pulmonary sequelae inpatients infected with SARS-CoV-2. It is therefore essential to evaluate the evolution ofthe respiratory status of the most severe patients who have had a stay in intensive carewith respiratory assistance.

The purpose of the study is to Assess of Long-term impact post COVID for patients andhealth care professionals.The patients and medical staff will be followed for 2 years inorder to provide clinical and paraclinical data not yet published in the literature.

The COVID-19 (coronavirus) pandemic has had a huge impact on healthcare resources andstaff in the UK. Understanding the key risk factors associated with infection amongsthealthcare workers is essential for future pandemic response plans.Currently there are scarce data relating to the infection rates and associated factorsamongst healthcare workers in the United Kingdom (UK). Studies of infection rates inhealthcare workers have largely relied on the real-time reverse transcriptase-polymerasechain reaction (RT-PCR) test to date and it appears that Healthcare workers are twice aslikely to succumb to Coronavirus infection, when compared to the general population andthose from Black and minority ethnic (BAME) backgrounds appear to be particularly atrisk.Currently there is no evidence that the presence of SARS-CoV-2 (severe acute respiratorysyndrome coronavirus 2) antibodies provides seasonal or long term immunity to futureinfection.Therefore, this study aims to understand the current level of SARS-CoV-2 antibodypositivity and try to determine the likely risk to healthcare workers in the UK toCOVID-19 infection. This study hopes to find out whether certain individualcharacteristics will have an impact on likelihood of infection susceptibility andantibody response and determine the impact of the presence of antibodies on thelikelihood of future clinical infection over a 12 month period.The study involves an initial online survey and linkage to the recent antibody test, thena further online survey in 6 and 12 months' time. The data obtained will be linked todata that the Human Resources Department (HR) holds.Participants also have the option to partake in another antibody test at 6 and 12 months'time and linked to the data collected.

Performance of the LumiraDx SARS-CoV-2 Ag assay will be assessed by comparison to areference method.

The primary objective is to assess the ability of COVID-19 IgG and IgM assays to detectan immune response in COVID-19 patients in the Henry Ford Health System (HFHS), bothduring hospitalization and over the following 12 months.

COVID-19 has become a global problem. There is an urgent need to improve the diagnosisand screening of patients and healthcare workers for COVID-19 in the UK. Mask basedsampling is a method of detecting SARS-COV-2 (the virus responsible for COVID-19) in thebreath of suspected COVID-19 patients or healthcare workers in the mask that they wouldwear in hospital. The investigators have previously demonstrated the utility of thismethod in other respiratory infections, such as tuberculosis.This project aims to investigate the utility of mask-based sampling is a tool for thediagnosis and quantification of COVID-19 in breath and the implications in a healthcaresetting using three cohorts of participants. Initially we will compare the amount ofCOVID-19 detected by mask sampling compared with standard nasopharyngeal swab, which isthe current gold standard test, in patients who present to hospital with COVID-19symptoms.We will address the length of time COVID-19 is breathed out by people affected by thevirus and the how infectious the virus is over time in a cohort of symptomatic healthcareworkers who are isolating at home. This will allow us to understand how long someonestays infectious for and may have the potential to inform public health measures, forinstance when healthcare workers can return to work or duration of isolation. Finally wewill investigate asymptomatic carriage of COVID-19 by different healthcare workers indifferent areas of the hospital during a screening study. This will allow us tounderstand the extent of infection amongst healthcare workers and allow us to addresshospital acquired transmission.

The aim of this preliminary study is to describe the potential decline in forcedexpiratory volume in 1 second (FEV1) or forced vital capacity (FVC) as measured by homespirometry in high-risk subjects infected with COVID-19. We hypothesize that themagnitude of such a decline in FEV1 and/or FVC may be associated with clinicaldeterioration and hospitalization. The study will ultimately inform a larger subsequentRCT that will evaluate the efficacy of home spirometry in the early detection (prerespiratory symptoms) of respiratory complications and therefore prompt early medicalattention which is a key for improving outcome.

Lower Respiratory Tract infections are a common cause of admission to the intensive careunit. Children routinely receive antibiotics until the tests confirm whether theinfection is bacterial or viral. The exclusion of bacterial infection may take 48 hoursor longer for culture tests on biological samples to be completed. In many cases, theresults may be inconclusive or negative if the patient has already received antibioticsprior to the sample being taken.A rapid assay to detect the most likely cause of infection could improve the speed withwhich antibiotic therapy is rationalised or curtailed.This study aims to assess whether a new genetic testing kit which can identify thepresence of bacteria and viruses within hours rather than days is a feasible tool inimproving antibiotic prescribing and rationalisation of therapy in critically illchildren with suspected lower respiratory tract infection.

This is a multicenter prospective study that aims to investigate the clinical impact ofSARS-CoV-2 infection in pregnant women, pregnancy outcomes and perinatal transmission.
