COVID-19 Clinical Trials and Expanded Access

The recent Coronavirus Disease 2019 (COVID-19), has caused a global pandemic, and development of safe, effective vaccines is mandatory to return back to pre pandemic life. Many vaccines have been developed and requested by the authorities after the emergency license issued. The main mechanism of protection is through humoral and cell-mediated immune responses that might reduce the potential for disease development or severity. Cytotoxic T cells clear virus-infected host cells and contribute to control of infection. Preliminary data are now available indicating safty and effecacy of different vaccines . The vaccines were tolerated, with induction of neutralizing antibodies and antigen-specific T cells against the SARS-CoV-2 spike protein. The aim of this work is to evaluate the immune responses in adults, aged 25-65 years, up to 8 weeks after vaccination with a single and double doses live inactivated (Sinopharm), mRNA (Pfizer/ Biontech) and viral vector (Oxford/AZ- ChAdOx1 nCoV-19) vaccines. The Th1- response ( interferon-γ and tumor necrosis factor-α cytokine secretion by CD4+ T cells) and antibody production predominantly of IgG1 and IgG3 subclasses as well as CD8+ T cells mono, polyfunctional and cytotoxic phenotypes, will be also measured.

This study is a multicenter cross-sectional survey-based study conducted in four European countries (Czech Republic, Germany, Slovak Republic, and Turkey). An online questionnaire will be utilized to collect data from volunteer subjects following the STROBE reporting guidelines of cross-sectional studies.

The trial aims to assess the impact of cheap, licenced and widely available investigational products on the natural history of SARS-CoV-2 infection in 2 groups of patients - those with mild or moderate pneumonia (Cohort 1) and those with severe pneumonia (Cohort 2), through randomisation to non-identical placebo or intervention arm.

Platform with a mobile application to encourage the performance of respiratory exercises, controlled and supervised by physiotherapists. It also includes recommendations, frequently asked questions and the possibility of contacting by chat or video calls with experts to solve possible doubts. Currently, the application is ready for use, the registration of users and professionals is enabled and have 20 exercises divided into three intensity levels. It is available for all platforms (PC, ANDROID, iOS). presents a simple deployment, accessible to the entire population and does not require installation. In the future, investigators will include more languages, a greater variety of exercises and even other types of therapies. Investigators will also carry out the adaptation to functional diversity with subtitles and voice commands.

This national study will recruit expectant mothers with and without positive nasopharyngeal swabs for SARS-CoV-2, and aims to determine the seroepidemiology of SARS-CoV-2 amongst expectant mothers and their infants in the UK, the prevalence of vertical transmission of the virus or antibodies against the virus, and the effect, if any, on neonatal outcomes.

The aim of this study is to evaluate whether there are indicators of central sensitisation in patients post covid-19 infection.

During this exceptional health crisis, this study of the current care of a neurosurgical activity, which is essential in a University Hospital Centre, will enable us to better understand how we function, the response given to a population with the means at our disposal, the implementation of new therapeutic strategies and their limits, ethical reflection, and, how to pursue a distributive and quality medicine. The restriction of conventional medical resources to our care activity (resuscitation, personnel, operating theatre, constraints linked to the risk of contamination...) is leading to a new medical organisation imposing new Covid-19 standards, the description of which seems essential to us. A knowledge of the strategies to be adopted during a disaster health situation in order to continue providing care to the civilian population. How can we prevent the setting up of health care systems outside the cause of the health crisis? n triage medicine, Avoiding the "burn-out" of doctors struck by the health crisis.

A new pandemic, COVID-19, has spread rapidly around the world. She does not spare pregnant women. Little is known about the clinical course of pregnant women infected with COVID-19. As of April 1, 2020, six case series and one case report for a total of 61 pregnancies affected by COVID-19, all from the pandemic epicenter in China, except for one state case report -Unis, have been published. These preliminary reports suggest that pregnant women are not more seriously affected than the general population and show a certain gap with what we have observed in the care of pregnant women at HUS. For these reasons, additional information, especially from parts of the world other than China, as the severity of the disease can vary from country to country, is urgently needed to determine whether pregnant women with the disease of COVID-19 will not present with severe pneumonia to COVID-19.

An open-label, 56 day, single-center, exploratory, proof-of-concept study of the anti-viral effect of voclosporin (VCS) with an extended safety follow-up, up to 1 year. Study population are adult KTRs with positive SARS-CoV-2 infection with mild to moderate symptoms. At study entry, subjects are on standard therapy of dual immunosuppressive treatment of prednisone and tacrolimus (TAC), following randomization, 10 out of 20 subjects will remain on this therapy for the duration of the study, while the other 10 subjects will switch to VCS.

The aim of this study is to evaluate whether there are indicators of central sensitisation in patients post covid-19 infection.
