COVID-19 Clinical Trials and Expanded Access

The COVID-19 CHAMPS Study will obtain data on the physical and mental health and well-being of workers potentially exposed to the SARS-CoV-2 virus in the course of their duties. Included are a broad range of occupations including those working in the community (police officers, firefighters, emergency personnel, screening staff) as well as in permanent or temporary sites that care for patients (service staff, nurses, physicians and other health professionals). CHAMPS will obtain data on various exposure factors and health and create a registry of participants for extended follow up and sub-studies.

The aim of the study is to compare a treatment with doxycycline vs a placebo as soon as the patient is confirmed COVID-19 + and before the onset of oxygen dependence with the aim of reducing or even abolishing the cytokine explosion and thus the evolution towards a serious form of the disease which can lead to death. Three criteria support the rational use of tetrcycline in COVI-19 (1) The coronaviruses is known to bind to metalloproteases (MMPs) of the host, in particular to ensure viral survival. Tetracyclines are known to chelate zinc from MMPs. Their chelating activity may help inhibit COVID19 infection by limiting its ability to replicate in the host. (2) Tetracyclines may also be able to inhibit the replication of positive-polarity single-stranded RNA viruses, such as COVID19 (demonstrated on the dengue virus). (3) In addition, tetracyclines are modulators of innate immunity (anti-inflammatory activity), a property used in the treatment of inflammatory skin diseases for many years. These modulating effects are noted on several targets of innate immunity: They can decrease the expression of NFKB, the release of inflammatory cytokines such as TNF-α, IL-1β and IL-6, inhibit granulomas inflammatory and free radical release. Tetracyclines could therefore participate in limiting the cytokine release induced by COVID19. Their lipophilic nature and their strong pulmonary penetration could allow them to inhibit viral replication.

Hydroxychloroquine, a derivative of chloroquine (an antimalarial drug) with a weak immunosuppressive effect, is prescribed by some teams alone or in combination with azithromycin. No randomized controlled trials have demonstrated its efficacy, particularly in primary care in the early stages of the disease. However, currently available data suggest better efficacy if treatment is given early in the disease, before symptoms worsen. To date, the majority of COVID-19 patients treated in outpatient care, particularly in general practice, represent the majority of COVID-19 patients. It is essential to evaluate, in primary care, the efficacy and safety of hydroxychloroquine combined with azithromycin in Covid-19 patients in order to be able to implement this therapeutic strategy as soon as the first symptoms appear. We realize a randomized, controlled, open superiority trial, in 2 parallel groups (ratio 1:1).The main objective is to assess the efficacy of Hydroxychloroquine combined with azithromycin in COVID-19 patients in primary care, in add-on to standard of care, on unfavorable outcome defined by the onset of at least one of the following between D0 and D14: hospitalization, death or percutaneous O² saturation ≤ 92% in ambient air.

Few studies have reported the efficacy of HCQ in reducing the viral load and improving the severity of symptoms in hospitalized COVID-19 cases with serious respiratory infection. However, the prophylactic benefits of HCQ has not been clearly defined yet.

Prospective study evaluating the outcomes of implementation of a protective protocol for Covid-19 for patients and staff in a large endoscopy unit.

Since the novel coronavirus, SARS-CoV-2, was first reported in the Hubei province of China in December 2019, the US has become an epicenter for the pandemic, accounting for more than 220,000 cases and 4,800 deaths (CDC). The rapid spread of the associated disease, COVID-19, has overwhelmed healthcare systems in spite of unprecedented measures to reduce contagion. The resulting uncertainty with regard to the duration and magnitude of the pandemic and limited availability of resources and treatment have been detrimental to the mental health of frontline healthcare providers (NIH). Preserving the psychological wellbeing of these individuals is paramount to mitigating the effect of COVID-19 and delivering optimal patient care. Of particularly grave concern is how professional and personal distress caused by the COVID-19 pandemic will affect provider burnout (Lai et al. JAMA Network Open 2020). Professional burnout, characterized by emotional exhaustion, career de-prioritization, and loss of self-efficacy, represents a significant threat to the US healthcare system (Shanafelt et al. Ann Surg 2010; Han et al. Annals of Internal Medicine 2019). While burnout has been described as a reaction to chronic work-related stress (Melamed et al. Psychol. Bull. 2006), individual factors such as anxiety increase susceptibility to burnout (Sun et al. J Occup Health 2012). Although data suggests that occupational stress might amplify risk of anxiety (DiGiacomo and Adamson J Allied Health 2001), we have yet to understand how intensified anxiety among frontline providers during global health crises contributes to burnout. Similarly, it is unknown whether factors such as perceived organizational support (POS), a key driver of job satisfaction and performance (Muse and Stamper, J Managerial Issues 2007), modify anxiety and burnout under these circumstances. We hypothesize that diminished POS in response to the COVID-19 pandemic is associated with burnout and that this relationship is mediated by an increase in providers' anxiety. Delineating this relationship is a critical first step in developing interventions that ease the mental health burden of this pandemic and future crises for healthcare providers.

This study is being done to see if hydroxychloroquine is an effective treatment for COVID-19.

The Coronavirus disease 2019 (COVID-19) is causing a global pandemic with high morbidity and mortality among adults and mainly the elderly. Children seem to be little or not affected by this infection. It is estimated that children could be asymptomatic or pauci-symptomatic carriers and thus be vectors of the disease. This is why measures to close schools and confine populations have been decreed in a large number of countries, including France. However, there are only a few data on the prevalence of COVID19 disease in children. The deconfinement strategy depends on data on the prevalence of the disease, especially in children. Investigators propose to evaluate the incidence of Covid-19 in preschool and elementary schools children in the city of Nice (South of France) during the pandemic period using a local prospective study of 914 children

The project aims to clarify how immunity to SARS-CoV2 develops in humans and to investigate the possibility of finding patients with a particularly effective, neutralizing antibody response for future treatment. The project also aims to detail the virus's damage mechanisms in tissue.

The disease caused by the SARS-CoV-2 virus is a viral disease that infects the lungs, producing flu-like symptoms. Elderly infected patients and/or those with co-morbidities may suffer from acute respiratory distress syndrome due to pneumonia (COVID-19 disease). Given the high transmission, this virus has spread in recent months from Wuhan (China) to the whole world, becoming a global emergency pandemic. The lack of curative treatment for this disease justifies the need to carry out clinical trials that provide quality evidence on treatment options. Given the pathophysiology of the disease, which involves an uncontrolled inflammatory response of alveolar cells, a treatment that attenuates the cytokine cascade could be key in rescuing the patient's lung tissue. Mesenchymal cells, due to their immunoregulatory potential and regenerative capacity, can be an effective treatment for patients infected with the SARS-CoV-2 virus. In the present study we propose a therapy with undifferentiated allogeneic mesenchymal cells derived from umbilical cord tissue, a treatment whose safety has already been described in other clinical trials and that shows promising results in pilot studies carried out in China.
