COVID-19 Clinical Trials and Expanded Access

This is a phase 1 study in which healthy adult volunteers will receive BRII-196/BRII-198 or placebo and will be assessed for safety, tolerability, and pharmacokinetics.

A retrospective cohort study will be conducted using a large administrative database of U.S. hospitals to understand the volume-outcome relationship among patients hospitalized with COVID-19.

The purpose of this study was to conduct an epidemiological survey of the pediatric population via SARS CoV-2 IgG antibody testing in order to evaluate the incidence of asymptomatic infection and seropositivity among children and establish risk factors of infection and characterization of asymptomatic carriers. Additionally, among seropositive children, antibody titers will be explored in order to reach a better understanding of the relationship between immunity over time after different types of initial exposures. Methods Study Design and Population A prospective epidemiological survey was conducted in the Pediatric Emergency Department (ED) of the Shaare Zedek Medical Center, a tertiary medical center in Jerusalem, Israel, between October 2020 and January 2021. All patients presenting to the pediatric ED during the study period and requiring blood tests or and IV insertion for any clinical reason were considered eligible to participate in the study. The parents and/or legal guardians of these patients gave oral consent for an additional 1-3 ml of blood to be sent for Sars-CoV-2 antibody testing. In addition, all consenting parent/guardians filled out a comprehensive questionnaire regarding demographic background, past medical history, and specific Covid-19 details such as exposures to carriers, past PCR testing, symptoms etc. All patients with positive serology results were contacted by phone and updated of the test results. Laboratory testing All blood samples were collected in a clot-activator test tube. Initial testing was conducted using the Abbott SARS-CoV-2 IgG assay. A positive result was considered a value above 1.5 with 0.8 - 1.4 cosidered grayzone results. All positive and grayzone results were then retested in the DiaSoren LIAISON® SARS-CoV-2 S1/S2 IgG assay. Statistical Analysis Statistical analysis was conducted using SPSS Statistics for Windows, Version 25.0. Armonk, NY: IBM Corp. Clinical variables were analyzed using the Chi-squared test for categorical variables and the t-test for continuous variables. All statistical tests were two-way tests and P value of 5% or less was considered statistically significant.

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 project aims to investigate the sensitivity and specificity of the rapid antigen test compared to RT-PCR test performed on samples from the nasopharynx and the anterior nasal cavity and the oropharynx, respectively.

This is an adaptive Phase I trial of a vaccine consisting of autologous dendritic cells previously loaded ex vivo with SARS-CoV-2 spike protein, with or without GM-CSF, to prevent COVID-19 in adults.

The study has a retrospective and a prospective component. The retrospective component aims to review data of all airway management related SAEs in COVID 19 patients (between April and July 2020); hypoxemia, hypotension and cardiac arrest within 15 min of intubation. The prospective component aims to assess the incidence of COVID-19 infection in Airway Management Team members by means of an interview assessing their COVID19 status after participating in airway management in the period outlined above. This prospective interview component is starting in December 2020.

Approximately 20% of patients hospitalized with COVID-19 require intensive care and possibly invasive mechanical ventilation (MV). Patient preferences with COVID-19 for MV may be different, because intubation for these patients is often prolonged (for several weeks), is administered in settings characterized by social isolation and is associated with very high average mortality rates. Supporting patients facing this decision requires providing an accurate forecast of their likely outcomes based on their individual characteristics. The investigators therefore aim to: 1. Develop 3 CPMs in each of 2 hospital systems (i.e., 6 distinct models) to predict: i) the need for MV in patients hospitalized with COVID-19; ii) mortality in patients receiving MV; iii) length of stay in the ICU. 2. Evaluate the geographic and temporal transportability of these models and examine updating approaches. 1. To evaluate geographic transportability, the investigators will apply the evaluation and updating framework developed (in the parent PCORI grant) to assess CPM validity and generalizability across the different datasets. 2. To evaluate temporal transportability, the investigators will examine both the main effect of calendar time and also examine calendar time as an effect modifier. 3. Engage stakeholders to facilitate best use of these CPMs in the care of patients with COVID-19.

The use of personal protective equipment is mandatory for healthcare workers caring patient with COVID-19. To maximise the reduction of virus spread during clinical procedures involving the presence of healthcare workers, it is also recommended to patients to wear surgical facemask. Routine clinical procedures include cardio-pulmonary and strengthening exercises. During these exercises, the wearing of a face mask may be difficult to tolerate by patients, especially since they experience breathing difficulties due to the illness. Therefore, this study aims to verify the effects of the surgical facemask on breathing difficulties and exercise performance during a 1-minute sit to stand test.

The purpose of this study is to characterize microvascular reactivity on the forearm muscle using non-invasive near-infrared spectroscopy in critically ill COVID-19 patients, and to correlate its alterations with 28-day mortality in ICU COVID-19 patients.
