COVID-19 Clinical Trials and Expanded Access

A study on the clinical and psychological characteristics of patients with coronavirus disease 2019 (COVID-2019)

The purpose of this study is to determine if a CGRP receptor antagonist may potentially blunt the severe inflammatory response at the alveolar level, delaying or reversing the path towards oxygen desaturation, Acute respiratory distress syndrome (ARDS), requirement for supplemental oxygenation, artificial ventilation or death in patients with COVID-19 on supplemental oxygen. * BHV-3500, formerly "vazegepant", is now referred to as "zavegepant" (za ve' je pant). The World Health Organization (WHO) International Nonproprietary Names (INN) Expert Committee revised the name to "zavegepant" which was accepted by the United States Adopted Names (USAN ) Council for use in the U.S. and is pending formal adoption by the INN for international use.

This study will investigate the impact of the Double-Trunk Mask (DTM) on the reduction of oxygen titration in patients with severe hypoxemia.

This non-interventional, observational study retrospectively (and in parts prospectively) investigates, if a Covid-19 associated Nephritis, diagnosed by Urine-dipstick and further Urine-analyses on addmission, can help to predict later complications, adverse outcomes and later need for ICU-capacity in Covid-19 patients as well as can guide preventive strategies.

The research aim to collect large samples of COVID-19 disease patients with clinical symptoms, laboratory and imaging examination data. Screening the biological indicators which are related to the occurrence of severe diseases. Then, investigators using artificial intelligence (AI) technology deep learning method to find a prediction model that can dynamically quantify COVID-19 disease severity.

The clinical study aims at assessing whether early administration of Tocilizumab compared to late administration of Tocilizumab can reduce the number of patients with COVID-19 pneumonia who require mechanical ventilation. The clinical study includes patients with recent-onset COVID-19 pneumonia who require hospital care, but not invasive or semi-invasive mechanical ventilation procedures.

There is no evidence that the Bacille Calmette-Guérin vaccine (BCG) protects people against infection with COVID-19 virus. Two clinical trials addressing this question are underway, and WHO will evaluate the evidence when it is available. In the absence of evidence, WHO does not recommend BCG vaccination for the prevention of COVID-19. WHO continues to recommend neonatal BCG vaccination in countries or settings with a high incidence of tuberculosis. There is experimental evidence from both animal and human studies that the BCG vaccine has non-specific effects on the immune system. These effects have not been well characterized and their clinical relevance is unknown

Single blind randomized clinical trial designed to evaluate the efficacy of the combination of hydroxychloroquine and dexamethasone as treatment for severe Acute Respiratory Distress Syndrome (ARDS) related to coronavirus disease 19 (COVID-19). We hypothesize that dexamethasone (20 mg for 5 days followed by 10 mg for 5 days) combined with 600 mg per day dose of hydroxychloroquine for 10 days will reduce the 28-day mortality compared to hydroxychloroquine alone in patients with severe ARDS related COVID-19.

Prone positioning (PP) is an effective first-line intervention to treat moderate-severe acute respiratory distress syndrome (ARDS) patients receiving invasive mechanical ventilation, as it improves gas exchanges and lowers mortality.The use of PP in awake self-ventilating patients with (e.g. COVID-19 induced) ARDS could improve gas exchange and reduce the need for invasive mechanical ventilation, but has not been studied outside of case series.The investigators will conduct a randomized controlled study of patients with COVID-19 induced respiratory failure to determine if prone positioning reduces the need for mechanical ventilation compared to standard management.

The COVID-19 epidemic is causing a global health crisis. In France, it has imposed a major reorganization of the healthcare system. This emergency reorganization is unprecedented. It involved first, second and third line care. Following this reorganization and from the first days of confinement, a decrease in care activity not related to COVID-19 was observed in médical offices, in emergency services, and in secondary and tertiary care services. This decrease in activity could indicate a decrease in pathologies related to work, transportation or non-COVID-19 infections, due to a favourable effect of lockdown. Nevertheless, some health professionals report the opposite in the media and on social networks, an unusual increase in events (appendicular peritonitis treated late, increase in domestic violence, etc.), while others are surprised by a decrease in activity that is difficult to explain (leukaemia diagnoses by biologists, for example). One hypothesis is that such changes could be related to the reorganisation of the health care system or to the consequences of lockdown. The World Health Organization (WHO) recommends a systematic collection and analysis of patient safety incidents (also called "adverse events" in France). The objective is to assess the roles of the system and human factors in patient safety, in order to propose changes to the global system and local organisation. In France, there is a system for reporting serious adverse events related to care. Only 4% of the 820 serious adverse events reported in 2018 were reported by primary healthcare professionals (1). However, patient safety incidents in primary care are known to have specific mechanisms, types and mechanisms (2). We hypothesize that the COVID-19 health crisis may have induced unusual patient safety incidents through new mechanisms in a context associating reorganization of the healthcare system and population lockdown. Such a scenario requires the implementation of a massive collection of potential incidents and their systematic and well-structured analysis. Thus, the objective of our study is to describe patient safety incidents related to the reorganization of care and/or lockdown in the context of the COVID-19 health crisis (types, severity, mechanisms) reported by general practitioners in France. 1.
