Cardiometabolic disease may confer increased risk of adverse outcomes in COVID-19 patients by activation of the aldose reductase pathway, a trigger of the inflammatory cascade. The study team hypothesizes that aldose reductase inhibition with AT-001 (caficrestat) might represent a novel therapeutic approach to reduce inflammation and risk of adverse outcomes in diabetic patients with COVID-19. An open-label pilot study to assess safety, tolerability and efficacy of AT-001 in hospitalized COVID-19 patients with history of diabetes mellitus and heart disease will be conducted. Eligible participants will be treated with AT-001 1500 mg twice daily for up to 14 days. Safety, tolerability, survival and length of hospital stay data were compared with matched controls from a contemporaneous registry of COVID-19 patients.

The current COVID-19 pandemic is providing healthcare organizations with considerable challenges and opportunities for rapid cycle improvement efforts, in diagnostic and patient management arenas. Healthcare providers are tasked with limiting the use of personal protective equipment while minimizing unnecessary exposures to the virus. Results from real-time PCR tests to detect active COVID-19 infections may not be available in a timely fashion during emergent trauma assessments. Since the start of the COVID-19 pandemic, a rapidly expanding body of literature has identified a pattern of imaged lung abnormalities with CT and ultrasound (US) characteristic of an active viral infection. US evaluation provides a reliable, portable, and reproducible way of evaluating acute patients in a real time setting. During initial trauma evaluations, patients may also receive adjunct imaging modalities like the Focused Assessment with Sonography in Trauma (FAST) exam designed to discover life threatening findings that may require urgent interventions. We therefore propose a study expanding on the current FAST adjunct evaluation in the trauma bay that may include lung parenchyma imaging at the initial assessment to help stratify patients into low or high-risk groups for active COVID-19 infections. We believe the use of point of care US in the initial assessment of the trauma patient may help identify potentially infected individuals and aid ED providers to best directing subsequent laboratory and imaging evaluations for these patients, while further directing the necessary protective measures for additional team members involved in the care of the injured patient.

This is a platform trial to conduct a series of randomized, double-blind, placebo-controlled trials using common assessments and endpoints in hospitalized adults diagnosed with COVID-19. BET is a proof-of-concept study with the intent of identifying promising treatments to enter a more definitive study. The study will be conducted in up to 70 domestic sites and 5 international sites. The study will compare different investigational therapeutic agents to a common control arm and determine which have relatively large effects. In order to maintain the double blind, each intervention will have a matched placebo. However, the control arm will be shared between interventions and may include participants receiving the matched placebo for a different intervention. The goal is not to determine clear statistical significance for an intervention, but rather to determine which products have clinical data suggestive of efficacy and should be moved quickly into larger studies. Estimates produced from BET will provide an improved basis for designing the larger trial, in terms of sample size and endpoint selection. Products with little indication of efficacy will be dropped on the basis of interim evaluations. In addition, some interventions may be discontinued on the basis of interim futility or efficacy analyses. One or more interventions may be started at any time. The number of interventions enrolling are programmatic decisions and will be based on the number of sites and the pace of enrollment. At the time of enrollment, subjects will be randomized to receive any one of the active arms they are eligible for or placebo. Approximately 200 (100 treatment and 100 shared placebo) subjects will be assigned to each arm entering the platform and a given site will generally have no more than 3 interventions at once. The BET-C stage will evaluate the combination of remdesivir with danicopan vs remdesivir with a placebo. Subjects will be assessed daily while hospitalized. Once subjects are discharged from the hospital, they will have a study visit at Days 8, 15, 22, 29, and 60 as an outpatient. The Day 8, Day 22 and Day 60 visits do not have laboratory tests or collection of samples and may be conducted by phone. All subjects will undergo a series of efficacy and safety laboratory assessments. Safety laboratory tests and blood (serum, plasma and RNA) research samples on Day 1 (prior to study product administration) and Days 3, 5, 8, and 11 while hospitalized. Blood research samples plus safety laboratory tests will be collected on Day 15 and 29 if the subject attends an in-person visit or is still hospitalized. However, if infection control considerations or other restrictions prevent the subject from returning to the clinic, Day 15 and 29 visits may be conducted by phone and only clinical data will be obtained. The primary objective is to evaluate the clinical efficacy of danicopan relative to the control arm in adults hospitalized with COVID-19 according to clinical status (8-point ordinal scale) at Day 8.

This study is an observational registry of children with or suspected to have SARS CoV2 (COVID-19) admitted to pediatric intensive care units (PICU). This registry will help describe the prevalence, rate and severity of acute kidney injury (AKI) in children with Severe Acute Respiratory Syndrome Coronavirus-2(SARS CoV2) across the world. The registry will be developed using a point prevalence methodology and then full retrospective review. Once a week, from April through June 2020, data collection will occur in "real-time" to estimate a weekly point prevalence of AKI and renal replacement therapy (RRT). The operational definition of "patients under investigation" (PUIs) will be used to identify the denominator of patients to be studied. The PUIs will be cohorted into SARS CoV2 test positive, test negative, test pending, or test unavailable. The primary aim of this study is to deliver a global, objective data driven analysis of the burden of AKI in virus positive patients or patients under investigation (PUI) who are admitted to the pediatric intensive care unit.

This phase II expanded access trial will study how well tocilizumab works in reducing the serious symptoms including pneumonitis (severe acute respiratory distress) in patients with cancer and COVID-19. COVID-19 is caused by the SARS-CoV-2 virus. COVID-19 can be associated with an inflammatory response by the immune system which may also cause symptoms of COVID-19 to worsen. This inflammation may be called "cytokine storm," which can cause widespread problems in the body. Tocilizumab is a medicine designed to block the action of a protein called interleukin-6 (IL-6) that is involved with the immune system and is known to be a key factor for problems with excessive inflammation. Tocilizumab is effective in treating "cytokine storm" from a type of cancer immunotherapy and may be effective in reducing the inflammatory response and "cytokine storm" seen in severe COVID-19 disease. Treating the inflammation may help to reduce symptoms, improve the ability to breathe without a breathing machine (ventilator), and prevent patients from having more complications.

Coronavirus disease 2019 (COVID-19) is a novel infectious disease caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). This syndrome has been associated with high mortality, estimated to be about 1.7% of all infected in the US, though in those who develop acute respiratory distress syndrome (ARDS) in the context of the infection, mortality rates appear to be much higher, perhaps up to 70%. To avoid transmission of the virus, patient isolation has become the standard of care, with many hospitals eliminating visitors of any type, and particularly eliminating visitation to patients infected with COVID-19. These necessary, but restrictive, measures add stress to the ICU and particularly to the family members who are not only left with fear, but also many unanswered questions. In contrast to the Society of Critical Care Guidelines (SCCM) which recommend family engagement in the ICU and recent data from this study team which suggests engaging families in end-of-life situations reduces symptoms of Post-Traumatic Stress Disorder (PTSD) in family members, family members are now unable to say good-bye and unable to provide support to their loved-one throughout the process of the patients' ICU stay. The study hypothesizes is that these restrictive visiting regulations will increase rates of Post-intensive care syndrome- family (PICS-F) which includes symptoms of PTSD, depression, and anxiety and aim to evaluate for factors that either exacerbate these symptoms or protect from them.

Introduction: Survivors of acute respiratory failure develop persistent muscle weakness and deficits in cardiopulmonary endurance combining to limit physical functioning. Early data from the Covid-19 pandemic suggest a high incidence of critically ill patients admitted to intensive care units (ICU) will require mechanical ventilation for acute respiratory failure. Covid-19 patients surviving an admission to the ICU are expected to suffer from physical and cognitive impairments that will limit quality of life and return to pre-hospital level of functioning. In this present study, the investigators will evaluate the safety and feasibility of providing a novel clinical pathway combining ICU after-care at an ICU Recovery clinic with physical therapy interventions. Methods and Analysis: In this single-center, prospective (pre, post cohort) trial in patients surviving ICU admission for Covid-19. The investigators hypothesize that this novel combination is a) safe and feasible to provide for patients surviving Covid-19; b) improve physical function and exercise capacity measured by performance on 6-minute walk test and Short Performance Physical battery; and c) reduce incidence of anxiety, depression and post-traumatic stress assessed with Hospital Anxiety and Depression Scale and the Impact of Events Scale-revised. Safety will be assessed by pooled adverse events and reason for early termination of interventions. Feasibility will be assessed by rate of adherence and attrition. Repeated measures ANOVA will be utilized to assess change in outcomes from at first ICU Recovery Clinic follow-up (2-weeks) and 3- and 6-months post hospital discharge. Ethics and Dissemination: The trial has received ethics approval at the University of Kentucky and enrollment has begun. The results of this trial will support the feasibility of providing ICU follow-up and physical therapy interventions for patients surviving critical illness for Covid-19 and may begin to support effectiveness of such interventions. Investigators plan to disseminate trial results in peer-reviewed journals, as well as presentation at physical therapy and critical care national and international conferences.
