Active clinical trials for "COVID-19"

Measurement of aerosolisation during esophagogastroduodenoscopy (EGD) to compare two types of mouthpieces, conventional versus a new and commercially available one 'the droplet reduction mouthpiece B1'. This new mouthpiece is considered to reduce droplet spreading during EGD and therefore could be a good option for use in COVID-19 positive patients.

A new Rapid RNA test for Covid-19 has been developed by Professor Cui and his team at the Department of Engineering Science at the University of Oxford. This can give results in 30 minutes which is much faster than the routine PCR test, which often takes 2-3 days to produce results. In this study we aim to establish the sensitivity of the rapid RNA test, which has never before been evaluated clinically. Preliminary anecdotal evidence suggests that the test is easy to use and appears to give valid results. This initial trial aims to establish whether the sensitivity of this tests is above the threshold of 90%. We aim to include at least 173 patients with symptoms of Covid-19 in Watford General Hospital.

This study uses a population-based approach to increase uptake of COVID-19 testing within a highly segregated and underserved African American community in Chicago.

This study will conduct an evaluation of a program that is being implemented SickKids / Toronto Public health that provides take-home saliva testing kits in schools. Operationally, there is a planned randomization so that all schools have an equitable chance to receive the intervention at various time periods during the planned operational roll-out, which will require a staggered implementation consistent with the stepped-wedge study design. The study will leverage this chance implementation to do a robust evaluation of the public health intervention. Schools that are not being rolled out to week one, will begin in the "control phase" (testing at an assessment center) and transition to the program "intervention phase" (take home saliva kits available at schools) at a randomly assigned time (wedge) over a 6-week period with all schools receiving the program by the end of the study. The investigators will evaluate the impact of the program on SARS-CoV-2 case identification in schools.

A study to investigate Rhinoswab as an alternative method to combined throat and deep nasal (CTDN) swab for respiratory sample collection in children who present to the Royal Children's Hospital (RCH) for viral testing. Children and their parent/guardian will answer a short survey about their preferences. Laboratory staff will answer a short survey about handling the different samples.

Mixed-methods process evaluation of a residence-based asymptomatic SARS-CoV-2 testing participation pilot

This Lucira COVID-19 All-In-One Test Kit performance study will be used to establish the performance of the Lucira COVID-19 All-In-One Test Kit as compared to a known high sensitivity RT-PCR molecular assay. The results of this study will be used to demonstrate the Lucira COVID-19 'swab to result in 30 minutes' test kit is similar in performance to known high sensitivity best-in-class molecular assays performed in high complexity labs. The results of this study will be combined with other studies the Sponsor has underway and will support a FDA Emergency Use Authorization (EUA) of the Lucira COVID-19 All-In-One Test Kit. This performance study will include nasal swabs self-collected by study subjects at community-based locations with trained medical staff. A subject's participation in this study will consist of one study visit and one collection event. The subject self-collects a nasal swab sample according to Lucira COVID-19 Test Kit instructions and runs test according to Quick Reference Instructions (QRI). Following the Lucira COVID-19 All-In-One Test Kit self-collection will be an additional swab collection for reference method testing. One (1) additional NS specimen will be collected either by the health care professional or self-collection, prepared in Transport Medium and sent to a reference laboratory.

This study will determine the impact of pulmonary rehabilitation on quality of life, body composition and respiratory function in patients with a history of COVID-19.

This study is designed to compare the performance of the NOWDx COVID-19 Test to an emergency use authorized PCR test result. The intent is to show the rapid test device is comparable to a currently marketed device. The NOWDx COVID-19 Test is an in vitro lateral flow immunoassay intended for qualitative detection of total antibodies to SARS-CoV-2 in human whole blood (venous and fingerstick).

This is a prospective longitudinal census study conducted at a single center (DCI Inc., Henry Avenue, Philadelphia). The purpose of this study is to gain information about COVID-19 infection and antibody response in an in-center dialysis population. The investigators hypothesize that screening and surveillance for COVID-19 positive test (viral infection) and antibodies response to infection (potential immunity) in a dialysis center population within a high-prevalence region can provide foundational information to guide approaches toward prevention of COVID-19 related illness in a susceptible population. Participants will be given a questionnaire initially and monthly over the study period to find out whether they have had COVID-19 infection, hospitalization, or symptoms. A nasopharyngeal swab test for COVID-19 infection and a blood sample for COVID-19 antibody will be collected monthly for the study period.
