Active clinical trials for "COVID-19"

Collection of nasal/nasopharyngeal/throat swabs and blood samples from patients presenting at their designated care facility displaying symptoms of COVID-19 and undergoing a SOC SARS-CoV-2 test or those who have tested positive in the past to aid development, calibration and performance evaluation for the LumiraDx POC test.

Seroprevalence study of COVID-19 in Saint Petersburg, Russia is a regional longitudinal cohort study aiming to evaluate the spread dynamics of the COVID-19 disease in the population of Saint Petersburg. Clinically asymptomatic adults are sampled from the population using random digit dialing and tested for the presence of SARS-CoV-2-specific antibodies in the blood serum. Data collection and serial sampling of the same individuals spans four weeks and is conducted every two weeks in order to understand both the spread of the virus in the population.

This open label clinical trial is to evaluate two different doses of dexamethasone on the health outcome using World Health Organization ordinal scale at day 28 in hospitalized patients with COVID-19.

This is a randomized, double-blind, placebo-controlled, adaptive two-stage design, human phase 2 study, with add-on treatment arrangement of fluvoxamine or placebo on top of standard of care (base therapy: the actual proposed therapy of moderate SARS-CoV-2 infected patients according to "Hungarian Coronavirus Handbook", including antiviral and immunmodulant therapy and reconvalescent plasma therapy in serious cases as indicated by the investigator).

In order to control the COVID-19 pandemic, a policy for the diagnosis and screening of people likely to be infected with SARS-CoV-2 has been established The reference diagnostic test is RT-PCR on nasopharyngeal swab. Nasopharyngeal swabbing requires training, generates a risk of aerosolization and therefore viral transmission to the operator, and is unpleasant or even painful for the patient. RT-PCR is efficient, but time-consuming. It is therefore necessary to consider techniques that are less subject to difficulties of production and sampling, and less time-consuming. Tandem mass spectrometry on saliva samples is a promising option. A combined "mass spectrometry/saliva test" should provide faster results.

A Study of the relation of COVID-19 infection and its severity to upper and lower airway nitric oxide, upper airway viral load and lung function.

The purpose of this study is to explore the factors that can affect the development of severe cases in hospitalized patients with COVID-19, including basic diseases, laboratory parameters, and clinical manifestations; In addition,to explore whether Azvudine can reduce the mortality of hospitalized patients with COVID-19.

Randomized, Parallel Group, Active Controlled Trial

This study aims to collect convalescent plasma and use it as experimental treatment in critically ill Covid-19 patients in order to reduce mortality and length of stay in intensive care unit.

A prospective and retrospective cohort study. The objective will to determine the frequency of COVID-19 in pregnant and postpartum women hospitalized with flu syndrome, to evaluate clinical and laboratory predictors of COVID-19 progression and to determine the factors associated with adverse maternal and perinatal outcomes in healthcare centers in two states of Northeast Brazil.The study will be conducted including pregnant and postpartum women with clinical or laboratorial diagnosis of COVID-19, admitted in six healthcare centers in the Northeast of Brazil. All pregnant and postpartum women with clinical and/or diagnosis of COVID-19, attended in prenatal care, in emergency (maternity triage), high-risk pregnancy ward, obstetric intensive care unit and rooming-in ward will be included. The data will be collected in specific forms. The exams will be carried out by trained professionals within each institution.
