COVID-19 Clinical Trials and Expanded Access

Renal damage in patients hospitalized for ARDS in the ICU can also be related to multiple causes including, but not limited to, the consequences of hemodynamic fluctuations in these patients or the use of nephrotoxic drugs responsible for acute post-ischemic or toxic tubular necrosis. Frequently observed abnormalities of cioagumation may also have a potential impact on renal structures, particularly glomerular capillaries. The researchers wish to characterize and phenotype the renal impairment of patients hospitalized in intensive care with tables of severe Covid19 infections in ARDS: clinical, biological and histological (by performing post-mortem biopsies).

Surfactant replacement therapy (SRT) improves oxygenation and survival in NRDS and some infant ARDS. SRT was tried in adult ARDS with conflicting results. Research by Filoche and Grotberg helped to understand the failure of previous clinical trials and yielded a strong scientific rationale for SRT success, now allowing to design a new administration protocol for SRT in adults, to be tested by this clinical trial in COVID-19 adult ARDS patients. Patients will be randomized to receive either a bronchial fibroscopy alone (with aspiration of secretions) or a bronchial fibroscopy with administration of 3 mL/kg of a solution of poractant alpha diluted to 16 mg/mL and distributed into each of the 5 lobar bronchi.

Based on emerging experience and trials from countries affected early by the COVID-19 (COV19) pandemic, there is evidence that a subgroup of severely affected people develop a hyperinflammatory (HI) syndrome (COV-HI). Trials are in progress of cytokine inhibition and other immune modulation to treat COV-HI. This proposal aims to use a rapidly executed cohort study to characterise the clinical phenotypes of COV-HI in patients in the UK through an established and nimble network of clinicians and scientists with broad experience of identifying and treating HI. The aim is to confirm the COV-HI clinical phenotype and using routine data to try to infer the inflexion point where COV-HI emerges. This would enable refinement of the proposed treatment algorithm and translates to routine clinical practice to improve the outlook for COV-HI.

The use of both levamisole & Isoprinosine has both synergistic and complementary effect in the treatment of COVID 19 infection

Healthcare Workers (HCW) are at high risk for COVID-19. In addition to the risk of serious forms among HCW, significant absenteeism due to illness would have dramatic consequences in our ability to fight COVID-19. No coronavirus vaccine is available today and drug treatments are only at the start of clinical evaluation. Available since 1921, the bacillus Calmette and Guérin (BCG) is the most widely used vaccine in the world (> 3 billion doses administered) with an extremely low rate of adverse effects. BCG is indicated for the prevention of tuberculosis (TB), but more recent studies have shown that it also has nonspecific immune properties which may be interesting in the current COVID-19 epidemic. Data in mice and in humans have demonstrated protection conferred by BCG against viral respiratory infections such as influenza. In countries with high endemic TB, BCG decreases the incidence of acute respiratory infections by up to 80%, neonatal BCG vaccination has been shown to greatly reduce the risk of sepsis and of hospitalization of children for reasons other than TB. A recent study conducted in South Africa showed that re-vaccination with BCG in adults reduced the incidence of respiratory infections by 70% compared to unvaccinated controls. Beyond respiratory infections, BCG has also shown protective effects against inflammatory diseases. These non-specific beneficial effects are likely linked to the induction of "trained innate immunity", implying epigenetic and metabolic re-programming of innate immune cells. It is therefore possible that revaccination with BCG could significantly reduce the incidence and severity of COVID-19. Very recent ecological observations indeed suggest an inverse correlation between BCG vaccination coverage and the morbidity and mortality of COVID-19. In this context several trials began in Europe and Australia to evaluate the efficacy of BCG vaccination in populations at risk of exposure (HCW) or severe disease (elderly). This study is aligned with studies carried out in Australia, The Netherlands and Spain. In contrast to these latter studies, virtually all French study participants have been vaccinated in their childhood, since BCG vaccination was mandatory in France in neonates until 2007, and in HCW until recently. Therefore, the French study will be in a unique situation to evaluate the effect of re-vaccination with BCG in the context of BCG priming decades before revaccination.

JUPITER is an observational study protocol that aims to understand factors that can help prevent/mitigate the spread of COVID-19 and understand factors that help reduce disease progression in patients with COVID-19. We aim to accomplish this by obtaining self-reported historical and longitudinal data from study participants.

COVID-19 is a rapidly spreading and very contagious disease caused by a novel coronavirus that can lead to respiratory insufficiency. In many patients, the chest radiograph at first presentation be normal, and early low-dose CT-scan is advocated to diagnose viral pneumonia. Lung ultrasound (LUS) has similar diagnostic properties as CT for diagnosing pneumonia. However, it has the advantage that it can be performed at point-of-care, minimizing the need to transfer the patient, reducing the number of health care personnel and equipment that come in contact with the patient and thus potentially decrease the risk of spreading the infection. This study has the objective to examine the accuracy of lung ultrasound in patients with proven COVID-19 pneumonia.

This is a phase 1b, open-label study in adult healthy subjects. This clinical trial is designed to assess the safety, reactogenicity, and immunogenicity the combination of hAd5-S-Fusion+N-ETSD (Suspension for injection) and hAd5-S-Fusion+N-ETSD (Oral capsule) and to select an optimal combination dose for future studies.

As part of the Coronavirus Infectious Disease 2019 (COVID19) pandemic, the hospital care system is facing a major strain. Patients with SARS-Cov2 (severe acute respiratory syndrome coronavirus 2 ) infection can worsen very quickly, possibly presenting, within hours, severe respiratory failure requiring urgent specialized care. Therefore, it is essential to develop emergency assessment tools to assess relevant criteria to decide which patients must be kept under hospital monitoring and which patients can be treated on outpatient care. The aim of this study is to assess the efficacy of STST in the decision to hospitalize patients consulting emergency department for a SARS-Cov2 infection. The investigators wish to show that the addition of this test to the usual hospitalization criteria reduces the proportion of patients hospitalized 48 hours after their first visit to the emergency department.

A series of microbiota were correlated inversely with the disease severity and virus load. Gut microbiota could play a role in modulating host immune response and potentially influence disease severity and outcomes.
