Active clinical trials for "COVID-19"

The purpose of this study is to evaluate the safety and tolerability of single ascending IV dose administrations of GIGA-2050 in patients hospitalized with COVID-19.

This is a 2 part study where the first part (Phase 1) evaluates the safety of XVR011 and aims to identify the recommended Phase 2 dose. The second part (Phase 2) follows after the part 1 and evaluates whether XVR011 added to standard of care in patients hospitalised for mild to moderate COVID-19 is a safe, well tolerated, and effective treatment. Part 1 (Phase 1) is completed as per protocol. The sponsor does not intend to start Part 2 (Phase 2) due to change in company strategy for phase 2 design.

This is an observational COVID-19 study that uses wearable health monitoring technology to follow COVID-19 positive individuals to monitor persistent symptoms and any potential long-term complications or cardiovascular and behavioral impacts from the disease.

This is a randomized, multicenter, placebo-controlled, double-blind clinical study in patients hospitalized due to severe Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2) infection.

This is a platform study to investigate the effectiveness of a variety of non-prescription approaches for the treatment of non-hospitalized adults recently tested positive for COVID-19.

This study investigates whether donors with previous exposure to COVID-19 can pass their immunity by hematopoietic (blood) stem cell transplant (HCT) donation to patients that have not been exposed. Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is the virus that causes the COVID19 infection. This study may provide critical information for medical decision-making and possible immunotherapy interventions in immunocompromised transplant recipients, who are at high risk for COVID19 severe illness.

Subjects (125) will be randomized to one of five mouthrinses and will be asked to give a saliva sample immediately before and after a 30-60 second mouthwash. Saliva samples will be collected from subjects at 15-minute intervals thereafter up to one hour (15, 30, 45 and 60 min). The saliva will be used for RT-PCR detection of Severe Acute Respiratory Syndrome CoronaVirus 2 (SARS-CoV-2) and viral infectivity assays, along with quantitative cytokine and chemokine concentration (pg/mL, Luminex). Subjects will complete a short survey on the taste and experience of using the mouthwash. Peripheral blood will be collected at the end of salivary collection. Subjects, except controls, will be provided materials and oral hygiene instruction related to daily use of oral hygiene products. In the seven-day period between study visit one and study visit two, subjects will be directed to brush with Colgate toothpaste (at least twice per day) and rinse with the Colgate mouthrinse (according to on-label procedures). Controls are asked to carry out their typical oral hygiene regimen with the products they typically use. All subjects keep a daily diary of oral hygiene performance, product usage, COVID-19 symptoms and exposures. Subjects complete study visit two one week after the baseline visit during which additional salivary (1 time point, 2 mL of saliva over 5 min, no rinse) will occur and blood samples collected. each subject will undergo a periodontal exam.

This is a double blind, placebo controlled, phase III randomized controlled trial evaluating the effects of the dietary supplements vitamin C, vitamin D, vitamin K, and zinc versus placebo on the overall health, symptom severity, and symptom duration of outpatients diagnosed with SARS-CoV-2.

COVID-19 is a severe disease with poor prognosis in patients receiving in-center haemodialysis (HD). A population-based registry of >4,000 patients with a diagnosis of COVID-19 receiving kidney replacement therapy (either haemodialysis or kidney transplant recipient) highlighted a 21.1 fold higher 28-day mortality risk among patients on dialysis (n = 3,285), than the expected 1.2% mortality of propensity-score matched historical controls. Vulnerability in uraemic patients is a combination of intrinsic frailty, increased risk of infection and a high burden of comorbidities. In patients on HD, abnormalities in the immune response may contribute to relative hyporesponsiveness to vaccines. However, patients on HD appear to seroconvert at a similar rate compared to the general population after SARS-CoV-2 infection, suggesting a likelihood of vaccine efficacy but this population has been excluded from vaccine trials. The primary aim of this study is to evaluate antibody synthesis induced after Covid-19 vaccination in a French adult multicentric cohort of in-center haemodialysis patients. The second aim of this study is to identify vaccine non-responders among HD patients and to assess the clinical and biological risk factors associated with non-response.

COVID-19 can cause myocarditis, which can cause myocardial fibrosis. This has been shown to increase mortality and morbidity among athletes. Several efforts have been made to guide sports participation after COVID-19, but not much scientific evidence is present to back-up those guidelines. The current initiative aims gain a heightened insight in this matter.To identify the presence of fibrosis athletes who recovered from COVID-19 will undergo CMR (Cardiac MRI). All athletes will also undergo echocardiography, 5-day Holtermonitoring among others. This will allow to determine whether differences between those with and those without fibrosis are present. If fibrosis is present, athletes will be offered an implantation of a very small monitoring device that will be able to detect arrhythmias with a much higher sensitivity. Also an exercise echocardiography will be performed, to determine the safety of continuation of athletic efforts. Amendment: Recently myocarditis and pericarditis have also been observed after the administration of mRNA-vaccines, specifically after the second dose. The effect of vaccination on exercise capacity is less clear. To investigate this we propose to amend the inclusion criteria for COVIDEX with "athletes undergoing or having undergone COVID vaccination"
