COVID-19 Clinical Trials and Expanded Access

The COVID-19 pandemic and the accompanying lockdown measures have made mental health a pressing public health concern. Acts that focus on benefiting others-known as prosocial behaviors-offer one promising intervention that is both flexible and low cost. However, neither the range of emotional states prosocial acts impact nor the size of those effects is currently clear, both of which directly influence its attractiveness as a treatment option. Using a large online sample from Canada and the United States, the investigators will examine the effect of a three-week prosocial intervention on two indicators of emotional well-being (happiness and the belief that one's life is valuable) and mental health (anxiety and depression). Respondents will be randomly assigned to perform prosocial, self-focused, or neutral behaviors each week. Two weeks after the intervention, a final survey will assess whether the intervention has a lasting effect on mental health and emotional well-being. The results will illuminate whether prosocial interventions are a viable approach to addressing mental health needs during the current COVID-19 pandemic, as well for those who face emotional challenges during normal times.

This study aims to evaluate the safety and reactogenicity profile after 1 and 2 dose administrations of investigational SARS-CoV-2 mRNA vaccine (CVnCoV) at different dose levels and to evaluate the humoral immune response after 1 and 2 dose administrations of CVnCoV.

The aeronautical community was also affected and greatly impacted economically and socially by the Covid-19 pandemic. Away from the acute phase, the epidemiological impact and the consequences of this disease within the French aviation flight crew population must be assessed. This study is aimed at providing original epidemiological data among civil and military aircrew, prior to possible prevention strategies or countermeasures to optimize risk management in terms of aviation safety and to promote, if necessary, future targeted studies.

To evaluate pulmonary changes and the results of a cardiopulmonary rehabilitation protocol (CPRP) in patients after SARS-VOC-2 infection. Clinical trial type study to be conducted between 2020 and 2024 involving clinical-functional cardiopulmonary imaging and blood transcriptome profile: before CPRP (T1), 2 months after CPRP (T2) and 1 year later (T3). Expected results: a) clinical, image and transcriptome changes; b) clinical-functional improvement after CPRP.

COVID-19 is a disease caused by the virus, SARS-CoV-2. Patients with this viral infection are at risk for developing pneumonia and acute respiratory distress syndrome (ARDS). Approximately 20% to 30% of hospitalized patients with COVID-19 and pneumonia require intensive care for respiratory support. Clinically, ARDS presents with severe hypoxemia evolving over several days to a week in combination with bilateral pulmonary infiltrates on chest X-ray. Widespread alveolar epithelial cell and pulmonary capillary endothelial injury can lead to severe impairment in gas exchange. In one report of 1,099 patients hospitalized with COVID-19, ARDS occurred in 15.6% of patients with severe pneumonia. In a smaller case series of 138 hospitalized patients, ARDS occurred in 19.6% of patients and in 61.1% of patients admitted to an intensive care unit (ICU). To date, no effective treatment has been established to treat COVID-19 or to prevent progression of ARDS. It is thought that a heightened immune response with an unbalanced release of inflammatory mediators in the airway is a major cause of morbidity and mortality associated with the disease. It is therefore reasonable to postulate that improved outcomes may be obtained in patients with a balanced immune response with adequate viral control and appropriate counter-regulatory immune responses whereas a poor outcome may be expected in patients with inadequate viral control or a heightened immune response or what is referred to as a "cytokine storm". Thus, modulating the pulmonary immune response without suppressing the immune system would be a viable strategy for patients with COVID-19. The current literature supports the role of neuromodulation, particularly vagal nerve stimulation (VNS), in modulating the immune response. Modulating the pro-inflammatory pathway through VNS has been demonstrated to decrease inflammatory mediators and improve outcomes in several animal models and in humans. Percutaneous electrical nerve field stimulation (PENFS) provides a novel, non-invasive method of VNS through a non-implantable device applied to the external ear. Already, the FDA has cleared this technology for reducing symptoms of opioid withdrawal in patients with opioid use disorder. Symptoms of opioid withdrawal can be decreased by approximately 90% after 1 hour of stimulation. Similarly, the IB-Stim device has been shown to improve symptom in children with abdominal-pain-related functional GI disorders and recently received market approval by the FDA for that indication. Unpublished studies have demonstrated marked decrease in inflammation with PENFS compared to sham stimulation in a model of TNBS colitis. While the efficacy of PENFS in modulating the progression of pulmonary disease in patients with COVID-19 is unknown, several proposed mechanisms for regulation of the immune response through VNS have already been demonstrated. We propose to perform an open label, randomized study to evaluate the efficacy of PENFS for the treatment of respiratory symptoms in patients with COVID-19.

North-east area of France was hit in February 2020 by the new coronavirus disease, more severely than other French regions. Factors affecting the evolution of the disease and its severity have been quickly identified, among them figuring different kinds of immune deficiency. Even if nowadays HIV infection is usually well controlled by ARV drugs, those patients with uncontrolled viral load and/or low CD4 cell counts, remain at higher risk of severe COVID infection. In this context, the primary objective of our study is aimed at evaluating the prevalence of SARS-CoV-2 antibodies in a cohort of HIV-infected patients followed-up in an HIV-infection care center. Secondary objectives are: evaluating whether the antibodies are protective or not, the kinetic of these antibodies, and HIV associated factors with the presence of antibodies.

Keeping in mind the rising number of cases in Egypt and the strain they put on hospital infrastructure, the idea of home isolation and follow up for COVID 19 positive cases has been adopted in many countries and was approved by World Health Organization (WHO) and Egyptian Ministry of health (MOH). Telehealth can help to mitigate this risk by minimizing the amount of face-to-face interactions. The WHO mentioned telemedicine among essential services in "strengthening the Health Systems Response to COVID-19" policy. The aim in this study is to study the effectiveness of telemedicine in managing mild COVID cases regarding isolation measures, symptoms, medications adherence, and reporting of red flags and side effects.

The current pilot study will explore the optimal cost-effective treatment configuration for online group-based weight control by focusing on two aspects of our existing treatment program which have significant associated cost and determine which contribute meaningfully to weight loss outcomes. Specifically, we will explore whether adding synchronous group social support (weekly group video chat sessions facilitated by a trained weight loss counselor) to on demand (asynchronous) social support provided through the program discussion board significantly increases weight losses achieved. We will also examine whether detailed feedback on dietary and physical activity self-monitoring records from a counselor enhances weight loss outcomes in comparison with basic feedback. Finally, we will examine the cost efficiency of the treatment constellations. Further, this pilot study will also explore the feasibility of recruiting participants nationally (rather than just locally) and the capture of data electronically (including body weight measurements) without any in-person contact.

This study proposes to evaluate the therapeutic efficacy, immunologic effects and normalization of laboratory parameters for patients at high risk for mortality when infected by SARS-CoV-2 (COVID-19) when administered one unit (approximately 200 mL) of convalescent plasma administered over a period of one hour. Following administration of the convalescent plasma, physical exam/clinical assessment information is collected daily and routine lab result data is collected every three days.

This study investigates a new diagnostic test in detecting SARS-CoV-2, the virus that causes the disease COVID-19. This may help to improve testing for COVID-19.
