Filter by:This is an adaptive Phase I-II trial of a vaccine consisting of autologous dendritic cells previously loaded ex vivo with SARS-CoV-2 spike protein, with or without GM-CSF, to prevent COVID-19 in adults.
Sarilumab is an anti-interleukin-6 human monoclonal antibody, such as tocilizumab, which is administered subcutaneously every two weeks for the treatment of moderate to severe active rheumatoid arthritis in adult patients. Despite the effectiveness reported for tocilizumab in the recently published experiences, the need to rapidly find alternative therapies to manage the complications of Covid-19 infection remains extremely high. The lack of clinical experience on the usage of sarilumab in such patients prevents the possibility of adopting early access programs for using commercially available sarilumab (prefilled syringe) packs in patients with severe Covid-19 pneumonia. The present study is aimed to generate a rapid, still robustly documented, evidence on the potential clinical efficacy and tolerability of a further IL-6R antagonist in Covid-19 pneumonia.
There is an evidence gap in relation to the incidence, impact and severity of COVID-19 in newborn babies. International data are very limited, we have no robust estimates of incidence and no UK-based data with which to inform policy, clinical care, service delivery or advice to pregnant women. The research aims are to investigate the three mains ways in which COVID-19 might affect newborns and babies that need neonatal care: 1. Newborn babies might catch COVID-19 before, during or soon after birth and this may lead to problems with breathing or feeding that need support in hospital. 2. COVID-19 could affect babies that are already on neonatal units with other medical conditions (like being very premature) that place them at greater risk of severe COVID-19. 3. COVID-19 might affect that way that pregnant women are looked after in pregnancy, labour or bith which could lead to problems for some babies, even if they do not themselves become infected with COVID-19.
The aim of this study is to reduce pulmonary complications in adult patients undergoing abdominal or thoracic surgery in COVID-19 exposed hospital environments. A Trial in Low and Middle Income Countries (LMICs)
The 2019 novel coronavirus disease (COVID-2019) pandemic is an enormous health issue of worldwide scale. Prevention and/or treatment with a widely-available and already-licensed product such as vitamin D (cholecalciferol) could have a large impact on healthcare worldwide. Given ethnic variation in vitamin D production, this could help to address the discrepancies in how people of different ethnicities are affected by COVID-19. There are currently no published studies analysing either individual-level evidence on the effect of vitamin D status on COVID-19 outcomes, or any prospective studies planning on following-up patients with reference to vitamin D and COVID-19 infection. The study will have 2 arms. Arm 1 will recruit patients hospitalised with COVID-19. Vitamin D levels will be measured in these patients and compared with outcome measures of COVID-19 severity. In Arm 2, patients will be recruited prospectively from local general practices (GPs) with measurement of vitamin D levels at enrolment. They will be followed up after 6 months to determine whether baseline vitamin D levels correspond with developing COVID-19. Data will be collected from a mixture of patient medical records, electronic patient records, laboratory data and from patients themselves. Data in Arm 1 will be analysed with a combination of linear and logistic regression, as appropriate, and with adjustment for covariates. Data in Arm 2 will be analysed as a case-control study, with adjustment for covariates. The primary objectives are to determine whether vitamin D levels affect outcomes in COVID-19 infection and whether vitamin D deficiency is associated with increased risk.
A novel coronavirus disease 2019 (COVID-19) outbreak is a global dramatic pandemic that is immeasurably impacting the communities. Due to lack of data, symptomatic management is used for COVID-19 infection including oxygen therapy and mechanical ventilation for those with severe infection. Considering immunomodulatory, anti-inflammatory anti-fibrotic and anti-oxidant actions of vitamin D, it's safety and ease of administration, as well as direct effects of vitamin D on immune cell proliferation and activity, pulmonary ACE2 expression and reducing surface tension, evaluation of vitamin D supplementation as an adjuvant therapeutic intervention could be of substantial clinical and economic significance. High prevalence of vitamin D deficiency in elderly, smokers, patients with chronic diseases and excess uptake by adipose tissue in obesity make investigations of its role as a secondary therapeutic agent in COVID-19 conceivable. It should be necessary to monitor serum 25(OH)D levels in all inpatient and outpatient populations with COVID-19 to identify the importance of maintaining or promptly increasing circulating levels of 25(OH)D into the optimal range of 100-150 nmol/L. The aim of this study is to conduct a double blind, randomized, controlled three weeks clinical trial on the efficacy of vitamin D (daily low dose versus weekly high dose) in COVID-19 patients in order to determine the relationship between baseline vitamin D deficiency and clinical characteristics and to asses patients' response to vitamin D supplementation in week three and determine its association with disease progression and recovery. Subjects who are randomized to high-dose will be asked to take 50,000 IU for two times during the first week and one dose over second and third weeks to quickly raise their serum levels. Subjects in the low-dose arm will take vitamin D 1000 IU daily for three weeks.
This is a phase 1b, randomized, blinded, placebo-controlled study in adult subjects with COVID-19. This clinical trial is designed to assess the safety and immunostimulatory activity of N-803.
The management of patients with SARS-CoV2 in respiratory distress can expose to corneal or retinal lesions induced by the stay in intensive care. Examination by ophthalmologists would make it possible to detect the most of the ophthalmologic problems known in intensive care and to provide an early, preventive or curative therapeutic response when possible, in order to avoid irreversible visual loss. The object of the research is to assess the presence and the importance of surface ophthalmologic lesions, the presence and the importance of retinal or optic nerve lesions, in order to improve the monitoring and primary prevention of this population
In December 2019 in the city of Wuhan in China, a series of patients with unclear pneumonia was noticed, some of whom have died of it. In virological analyses of samples from the patients' deep respiratory tract, a novel coronavirus was isolated (SARS-CoV-2). The disease spread rapidly in the city of Wuhan at the beginning of 2020 and soon beyond in China and, in the coming weeks, around the world. Initial studies described numerous severe courses, particularly those associated with increased patient age and previous cardiovascular, metabolic and respiratory diseases. A small number of the particularly severely ill patients required not only highly invasive ventilation therapy but also extracorporeal membrane oxygenation (vv-ECMO) to supply the patient's blood with sufficient oxygen. Even under maximum intensive care treatment, a very high mortality rate of approximately 80-100% was observed in this patient group. In addition, high levels of interleukin-6 (IL-6) could be detected in the blood of these severely ill patients, which in turn were associated with poor outcome. From experience in the therapy of severely ill patients with severe infections and respiratory failure, we know that treatment with a CytoSorb® adsorber can lead to a reduction of the circulating pro- and anti-inflammatory cytokines and thus improve the course of the disease and the outcome of the patients. The aim of the study is to investigate the influence of extracorporeal cytokine adsorption on interleukin-6-levels and time to successful ECMO explantation under controlled conditions in patients with particularly severe COVID-19 disease requiring extracorporeal membrane oxygenation.
This study compares two intubation boxes, that is the Taiwan "Aerosol Box" versus the UMMC "Intubation Box". The importance of this intubation box has come to light recently in view of the COVID-19 pandemic and the fact that intubation is an aerosol-generating procedure. Risks of the healthcare worker attending to the airway of COVID-19 patients is high and the intubation box aims to minimize that and reduce contamination of the environment. The original design of the "Aerosol Box" has limitations and is not easily used by intubators. This study evaluates the clinical usefulness of an innovation of the "Aerosol Box" design that is made to be more ergonomic and increases the rate of successful intubation. Anaesthetists with more than 5 years of clinical experience in intubating airways as well as more than 20 successful intubations using videolaryngoscopy , will be available to participate. This study will employ manikin and will be a randomized cross-over trial, conducted in UM.
