COVID-19 Clinical Trials and Expanded Access

The purpose of this study is to investigate whether nicotinamide riboside supplementation can attenuate the severity of SARS-CoV-2 infections in elderly patients. A major event in aging is the loss of the central metabolite nicotinamide adenine dinucleotide (NAD+) that appear to be important in the proinflammatory environment that occur during aging. Notably, recent work from our and other groups suggest that aging can be ameliorated by even a short-term treatment of the NAD+ precursor nicotinamide riboside. Nicotinamide riboside has recently been shown to be able to return aging tissues to a younger state even after short term treatment. This vitamin B3- analog is naturally occurring, is readily taken up through oral administration and has been tested in human trials with few side effects. In this randomized double blinded case-control trial, the investigators will treat elderly (>70 year old) COVID19 patients with 1 g of nicotinamide riboside (NR-E) or placebo for 2 weeks and investigate if this affects the clinical course of the disease.

To date there is no brain imaging and olfactory data available in COVID-19 positive patients with anosmia. By describing the pathophysiological characteristics underlying the olfactory symptoms and clinical characteristics of COVID-19 infection, the study investigators wish to compare the MRI aspects obtained in COVID-19 patients with and without anosmia, in the absence of other underlying neurological disorders.

The Covid-19 viral pandemic has caused significant global losses and disruption to all aspects of society. One of the major difficulties in controlling the spread of this coronavirus has been the delayed and mild (or lack of) presentation of symptoms in infected individuals, and the insufficient Covid-19 testing capacity in the UK. This warrants the development of alternative diagnostic tools that reliably assess Covid-19 infection in the early stages of infection, while also being low- cost, low-burden, and easily administered to a wide proportion of the population. This study aims to validate machine learning models as a diagnostic tool that predicts infection with SARS-CoV-2 based on app-reported symptoms and phenotypic data, against the 'gold-standard' swab PCR-test. This study will take place within the Covid Symptom Study app, the free symptom tracking mobile application launched in March 2020.

COVID-19 is a rapidly evolving pandemic with approximately 5% of all patients which require intensive care unit admission. In critically ill patients infected with COVID-19, approximately 15% had severe shock requiring medications to increase blood pressure. It appears that blood vessel tone is altered and microcirculation is not well regulated in patients with COVID-19. The underlying pathophysiology and contributing factors are unknown. The association with subsequent organ dysfunction and outcome is also unclear. Therefore, the investigators aim to investigate serial changes of relevant biomarkers in this population to improve the understanding of this disease, to investigate the association with clinically important outcomes and to find out how best to treat patients. The data will serve to develop strategies for individualised management of this high-risk group.

This study aims to find out whether the use of angiotensin II, which is a drug to raise blood pressure has been approved by European Medical Agency in August 2019, as an add-on medication to increase blood pressure in patients with COVID-19, acute severe lung injury, inflammation and severe shock, compared with standard medication. In addition, the investigators will collect the data of Anakinra, another drug which is frequently used in this condition to reduce inflammation. The investigators will collect clinical data and outcomes from critical care patients. The investigators will analyse for whom these drugs are most beneficial and explore whether there are any patients who don't benefit or have side effects.

This is a multicenter, Phase 2 study, to assess the efficacy of the treatment with convalescent plasma in patients with severe COVID-19 infection.

This research aims to investigate the role of daily measurement of urinary cell cycle arrest markers and other serum and urinary biomarkers to predict the development of acute kidney injury in critically ill patients with COVID-19 and acute respiratory disease.

COVID/Homeless is a prospective observational cohort study of homeless people to determine the impact of the SARS-CoV-2 epidemic on this population. The cohort aims for exhaustiveness for the city of Marseille, being based on the active files of the partner teams, namely the four emergency shelters of Marseille and 12 outreach teams (including one specialized in psychiatry, three specialized in addictions, and three working in squats and shantytowns). Aims of this cohort include to identify of the prognostic factors of morbi-mortality of homeless people by COVID-19, and therefore to propose appropriate management strategies.

During the current COVID-19 pandemic many spinal cord injury (SCI) rehabilitation services are limited to emergency management, leaving those living in the community without access to services. Unfortunately, this can lead to negative effects including increase in emotional distress, feelings of isolation, and decreased activity engagement. Due to their limited mobility and greater likelihood of respiratory illness it is imperative to provide alternative forms of activity engagement to reduce their risk for secondary complications. Physical activity has been demonstrate to have numerous benefits for individuals with SCI ranging from enhanced health through prevention of secondary complications to improved subjective well-being. The current study proposes to provide an online physical activity program through web-based videoconferencing to person with SCI to improve overall wellbeing and activity engagement. The program will consist of six weeks of twice-weekly, 45-minute sessions in which an experienced fitness instructor (i.e., wheelchair aerobics) with lived experience and a Kinesiology graduate student will lead online sessions. The sessions will be comprised of a 10-minute warm-up phase, a 25-minute aerobic phase and a 10-minute cool-down phase that will incorporate upper-extremity flexibility exercises and guided meditation. In all cases, remote (i.e., in-home) participant monitoring of physiological signals will be conducted by the instructor to ensure safety of participants. Once the program has been completed, participants will be asked to complete self-report questionnaires related to acceptability, feasibility, and limited effectiveness. Participants will also be asked to complete a brief semi-structured interview examining barriers and facilitators of the program. Participant feedback from the interviews will be used to further develop of the program to meet the needs of the population and develop sustainable approaches for access to care in the community setting through collaborations with community partners (SCI Ontario, National SCI Alliance, Ontario Neurotrauma Foundation). Ultimately, the proposed project aims to improve overall wellbeing and access to health care service for those with SCI during the COVID-19 quarantine.

Coronavirus disease (COVID-19) is an infectious disease caused by a newly discovered coronavirus. At this time, there are no specific vaccines or treatments for COVID-19. However, there are many ongoing clinical trials evaluating potential treatments Drugs used to treat malaria infection has shown to be beneficial for many other diseases, including viral infections. In this Clinical trial, Investigators will evaluate the effect of Artemisinin / Artesunate on morbidity of COVID-19 patients in decreasing the course of the disease and viral load in symptomatic stable positive swab COVID-19 patients. Investigators are hypothesizing that due to the antiviral properties of this drug it will help as a treatment for the COVID -19 patients. In improving their condition and clearing the virus load,
