COVID-19 Clinical Trials and Expanded Access

We hypothesize that the intake of Omni-Biotic® 10 AAD can reduce intestinal inflammation and improves dysbiosis in Covid-19 disease. We further hypothesize that Omni-Biotic® 10 AAD can reduce the duration of diarrhea, stool frequency, improve stool consistency, improve other gastrointestinal symptoms of Covid-19, reduce disease duration and severity. The investigators aim to perform a randomized, double blind, placebo-controlled study using telemedicine in patients with Covid-19 disease.

The objectives of this research is to: - Assess perceptions, concerns, and practices related to the COVID-19 pandemic and mitigation strategies using the MURDOCK Study Community Registry and Biorepository population as a measure of these features in Cabarrus County through a biweekly electronic survey. - Estimate the prevalence and change in prevalence of COVID-19 infection based on responses to questionnaire items on symptoms and practices using a biweekly electronic survey. - Among respondents to the baseline questionnaire, conduct at home mid-turbinate nasal swab collection for viral PCR testing for active COVID-19 infection as an estimate of the prevalence of active infection in Cabarrus County. - Among respondents to the baseline questionnaire, conduct serologic testing for IgG antibodies to SARS-CoV-2 as an estimate of the prevalence of exposure and potential immunity to COVID-19.

The reason for this study is to see if the study drug baricitinib is effective in hospitalized participants with COVID-19.

This project is based in the implementation of a combined monitoring system (technological solutions and medical visits) in survivors of the critical illness due to the infectious disease by COVID-19. The main objective of the project is to characterize the Post-Intensive Care Syndrome (PICS) and detect early needs for specific treatment.

COVID19-associated disease may have different clinical aspects classified in 3 stages. Some patients initially presenting with a non-hypoxemic viral pneumonia (stage 2a) may evolve toward a more severe stage 2b or 3 (acute respiratory distress syndrome, ARDS) around the 7th or 10th day of evolution, with a severe biological inflammatory syndrome (CRP>200 mg/l), and some times more severe complications such as acute renal insufficiency, consumptive coagulopathy or shock, requiring increasing oxygen therapy, ICU admission, invasive mechanical ventilation and possibly leading to death. This detrimental evolution is due to a host-derived "cytokine storm" with a great excess of circulating inflammatory cytokines. In animal models of ARDS complicating coronavirus or influenza virus infection, the cytokine storm has been linked to hyperactivation of the NLRP3 inflammasome. NLRP3 constitutes an intracellular protein platform which is responsible for caspase1 activation and processing of interleukin (IL)-1beta and IL-18 . IL-1b is a major proinflammatory cytokine which induces IL-6, whereas IL-18 is an inducer of interferon gamma (IFNg) production by Th-1 lymphocytes. A blood IL-1/IL-6 signature can be defined by increased neutrophilia and CRP concentrations, whereas an IL-18/IFNg signature is characterized by severe hyperferritinemia, consumptive coagulopathy and cytopenia. A majority of patients with COVID-19 infections seems to have an IL-1/IL-6 signature, evolving in the more severe forms toward an IL-18/IFNg signature, mimicking cytokine profiles observed in other inflammatory diseases such as Still's disease or hemophagocytic syndromes. In Still's disease, therapeutic inhibition of IL-1 or IL-6 has proven to be very efficient strategies. During hemophagocytic syndromes, inhibition of IFNg is effective in humans notably through blockade of its receptor signalization, using the JAK kinase inhibitor ruxolitinib. Following this strategy, we propose to use biological drugs currently available for inhibition of IL-1 (anakinra), IL-6 (tocilizumab) or IFNg signaling (ruxolitinib) in the severe forms of COVID19-associated disease. Our hypothesis is that IL-1, IL-6 or JAK kinase inhibition will allow: 1. to prevent stage 2b worsening and the need to be admitted in ICU, by decreasing oxygen-requirement and systemic inflammation 2. to improve stage 3 and extremely severe stage 3, allowing invasive mechanical ventilation weaning, improving multi-system organ dysfunction, leading to a faster ICU exit. We propose an open randomized therapeutic trial (1/1/1) on 216 patients with severe stage 2b and 3 of the disease

There is currently no clinically proven specific antiviral agent available for SARS-CoV-2 infection. Supportive treatment, including oxygen therapy, remains the most important management strategy. Since its discovery, lactoferrin and its related peptides are mainly considered to be important non-specific host defense molecules against a broad range of viruses including SARS-CoV, which is closely related to SARS-CoV-2 that causes COVID-19. Lactoferrin has been found to experimentally inhibit viral entry in murine coronavirus, and human coronaviruses hCOV-NL63 and pseudotyped SARS-CoV. Besides reducing viral entry, lactoferrin can also suppress virus replication after the viral entry. Another major aspect of lactoferrin bioactivity relates to its immunomodulatory and anti-inflammatory functions. Current thinking suggests that mortality from COVID-19 is not simply due to viral infection but is a result of a cytokine storm associated with hyper-inflammation leading to acute respiratory distress and subsequent mortality. A cytokine profile in severe COVID-19 cases is characterized by increases in cytokines and acute phase reactants and ferritin. In this regard, lactoferrin was demonstrated to reduce IL-6, TNF a, and downregulate ferritin in experimental settings simulating sepsis. In this study, we aim to study the potential application of lactoferrin against SARS-CoV-2 and propose the possibility of using different doses of supplemental lactoferrin as a potential adjunct treatment for COVID-19.

With the spread of COVID-19 epidemic since 2019 in Wuhan, China health plans have to be adapted continuously in response to the emergency. The first publications from the Chinese experience demonstrate an increase in the incidence of COVID-19 infections in patients over 60 years of age, a higher frequency of severe forms of the disease and therefore theoretical indications of orientation towards resuscitative care. However, the first published data from Hubei province suggest a low benefit of resuscitation for patients between 70 and 80 years of age and null in patients over 80 years of age. These data question the individual benefit / risk balance of an orientation towards resuscitation for this category of patients, their quality of life and the concept of unreasonable obstinacy. Among the covariates associated with resuscitation mortality described in the data published to date, cardiovascular comorbidities, certain biological covariates (LDH, creatinine, lymphocytes, neutrophils, TP, D-dimers, etc.), the time between the first symptoms and the entry into resuscitation have been identified. The objective of this multicentric observational study is to determine the clinical and biological covariates predictive of mortality in the population of patients over 60 years of age admitted in intensive care unit, in particular by integrating functional and nutritional data from patients 1 month before COVID-19 infection.

This multicentre prospective cohort trial is designed to demonstrate effectiveness and efficiency of a virtual care model for the management of COVID-19 patients isolating at home. The investigators have reoriented existing technology and networks for this research project. The investigators are amplifying our existing virtual care platform VIRTUES, combining it with home monitoring of COVID-19 patients, to provide real-time evidence, harmonize data collection, and share data provincially to mitigate the impact of the rapid spread of the virus. The study will facilitate early detection of complications associated with the disease, treatment and management of COVID-19 patients at home. The research will be conducted provincially in Ontario. This initiative will provide evidence to inform clinical and health system management and public health response to COVID-19 patients isolating at home.

The study objectives are to descript clinical, biological and echocardiographic features of an acute myocarditis in children in the context of COVID-19 and to identify the underlying mechanism : direct viral damage and/or inadequate host response risk.

The Covid-19 has, in a few weeks, made the world tremble: the number of deaths (mainly elderly and / or co-morbid) continues to increase, the confinement causes the collapsing of the economy and the decline of relationships inter-human. The data are too fragmented and the disease too recent to know its repercussions on the 3 million French people who have or have had cancer. The investigators would like, in 3 populations: * patients in treatment, * or in follow-up and * health personnel, to constitute a large prospective and longitudinal database of data: i / serological: humoral response, test performance, monitoring of serum immunoglobulin levels , reinfection threshold,…; ii / clinical: incidence, severity, mortality and their favorable factors impact of cancer treatment on Covid-19 infection and modification of the quality of oncological care in the context. In parallel, on a more limited sample of establishments, it will be : * appreciate the economic and functional repercussions, * will try to find out about the infection modalities in patients and health personnel and * will appreciate the levels of anxiety and depression to which health staff are subject.
