Filter by:The pandemic of coronavirus disease 2019 (COVID-19) caused by the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) has lately caused worldwide health problems. Patients suffering from a severe mental disorder are at increased risk for infectious diseases. The primary aim of the present surveillance study is to perform COVID-19 serological testing on patients with a diagnosis of schizophrenia, schizoaffective disorder or a bipolar affective disorder. Patients from the catchment area of the Capital Region of Denmark will be COVID-19 tested at baseline (0 months) and again at 6 and 12 months, in order to follow the spread of COVID-19 among this vulnerable patient population.
This is a phase II, observer-blind, multiple-centre, randomized, placebo-controlled study to evaluate the immunogenicity, safety, tolerability and lot consistency of 2 doses of UB-612 vaccine in adolescent, younger and elderly adults. Around 3850 adult subjects will be randomized to be composed of the core group, while around 385 adolescents will be randomized to be the supplementary group. Subjects will be unblinded at Visit 5, and subjects in the vaccine group will be encouraged to have 3rd dose of vaccination.
Patients with COVID-19 frequently develop lower respiratory complications. Difficulty breathing and a low concentration of oxygen in the blood are of concern in patients with COVID-19, as they indicate that the lungs may be significantly affected. In some patients, respiratory symptoms may progress to the point where oxygen support is needed (i.e. use of an oxygen prongs, mask or ventilator). The exact mechanism of why patients with COVID-19 develop low concentrations of oxygen in blood is not fully understood. Some data suggest that the Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2), the virus causing Coronavirus Disease 2019 (COVID-19), can affect the body's blood vessels directly and extensively. In the lung, blood vessels participate in the absorption of oxygen. Endothelin is a potent hormone produced by human blood vessels. When increased, endothelin can result in the narrowing of blood vessels in the lung and decrease the volume of blood flowing through the lungs. This decrease in in blood flow through the lungs may be one of many factors affecting normal lung function. Ambrisentan can block the effects of endothelin in the body, and this could theoretically improve blood flow through the lungs. This study will evaluate whether ambrisentan, by blocking the effects of the hormone endothelin in the lungs, improves the breathing capacity of patients with COVID-19, increases the concentration of oxygen in the blood and prevents the progression to respiratory failure and death. Ambrisentan is a drug that is currently used to treat patients with pulmonary hypertension, a disease where blood flow through the lungs is decreased. Subjects participating in this study are those patients hospitalised with severe respiratory symptoms related to COVID-19, and are considered to be at high-risk of developing respiratory complications. Ambrisentan will be administered in the hospital, and will be continued at home for up to 28 days. In this study, ambrisentan will be administered at much lower doses that those used in patients with pulmonary hypertension.
This study is being conducted to study the use and application of a point-of-care (POC) Covid-19 test developed by Spartan BioSciences and recently approved for clinical use by Health Canada.
This is an open-label unblinded, randomized study to treat hospitalized covid-19 patients with colchicine plus current care (per institution treating physicians) vs. current care per institution treating physicians alone (the control arm)
Monocentric open phase I (dose escalation component), followed by a multi-center, randomized, phase II component benchmarking IMP+SoC against SoC
There are several ways in which the COVID-19 pandemic may affect the prevention and management of thrombotic and thromboembolic disease, either direct effect or the indirect effects of infection, such as through severe illness and hypoxia, may predispose patients to thrombotic events. The severe inflammatory response, critical illness, and underlying traditional risk factors may all predispose to thrombotic events. Therefore, considering the high-risk profile of cardiovascular comorbidities in patients with COVID-19, it is scientifically relevant to evaluate the use of anticoagulants as an adjunctive treatment in the context of COVID-19. Indeed, it will be tested the hypothesis that the use of moderate dose of rivaroxaban has a beneficial effect in the treatment of patients with a confirmed or probable diagnosis of COVID-19 infection, with no clear indication for hospitalization (mild and moderate cases) upon initial medical care, by reducing the need of hospitalization due to complications related to COVID-19.
Niclosamide (2000 mg QD) and Camostate (600 mg QID) are expected to be safe and well-tolerated as a combination therapy and to show clinically beneficial for COVID-19 patients.
This is a Phase 2/3, randomized, double blind, placebo controlled, multicenter study to evaluate the efficacy and safety of FP-025 in adult patients with severe to critical COVID 19 with associated ARDS.
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.
