Active clinical trials for "Severe Acute Respiratory Syndrome"

The objective of this study is to determine whether oral NAC is effective at attenuating COVID-19 disease symptom severity and duration of symptoms.

This is a single center, single arm exploratory imaging study involving up to two intravenous microdoses of [18F]F-AraG (the second tracer dose is optional) followed by whole-body PET-CT imaging in participants with convalescent COVID-19. Up to 20 participants will be enrolled over an accrual period of approximately 24 months. Each participant will undergo one PET-CT scan following 50 +/- 10 minutes uptake following a single bolus injection of [18F]F-AraG in order to determine the tissue distribution of tracer in pariticpants with recent SARS-CoV-2 infection. A second optional [18F]F-AraG dose and PET-CT will be offered approximately 4 months following the initial imaging time point.

This is a prospective, multicentric, non comparative study aiming to evaluate the clinical and virological evolution of high-risk patients infected with SARS-CoV-2 treated withtin the framework of a cohort ATU ('Autorisation temporaire d'utilisation') or authorisation for early access (AAP) delivered by the French drug agency (ANSM).

This is a phase I/II, randomized, double-blind, placebo-controlled clinical trial that will evaluate the safety and potential efficacy of therapy with extracellular vesicles (EVs) obtained from mesenchymal stromal cells (MSCs), patients with moderate to severe acute respiratory distress syndrome due to COVID-19 or other etiology. Participants will be allocated to receive EVs obtained from MSCs or placebo (equal volume of Plasma-Lyte A). Blinding will cover the participants, the multidisciplinary intensive care team and the investigators.

Adults who do not have major health, kidney, gastrointestinal disease will be randomized to receive oral mitoquinone/mitoquinol mesylate (Mito-MES) versus placebo to prevent the development and progression of COVID-19 after high-risk exposure to a person with confirmed SARS-CoV-2 infection.

The protocol, in accordance with the objectives of ORCHESTRA project - Work Package 2, aims at investigating the characteristics and determinants of COVID-19 long-term sequelae. This goal will be reached through the harmonization of follow-up strategies across the participating cohorts to allow a standardized collection of data on COVID-19 long-term sequelae. The result will be a platform including a set of data and biomaterials from large scale international cohorts, that will be uniformly recorded, prospectively tracked and analysed. The ultimate goal will be that of providing evidence to contribute to the optimization and improvement of the management and prevention of COVID-19 sequelae. The follow-up will be organized in multiple levels of tests, according to the capability of each cohort, and will include questionnaires to collect demographic, epidemiological and clinical data, physical examination, radiological exams and biological sampling. The long-term follow-up will also allow the assessment of long-term immunological response to SARS-CoV-2 infection and its association to the vaccination and to different treatment strategies, including monoclonal antibodies.

VIDO has developed a vaccine called COVAC-1. The COVAC-1 study vaccine contains a portion of the SARS-CoV-2 spike protein, called S1. The spike protein is the part of the virus that is responsible for attaching to the surface of host cells. COVAC-1 contains a TriAdj adjuvant. An adjuvant is a compound that is added to a vaccine to help the vaccine produce a better immune response. The vaccine is expected to stimulate the body to make antibodies against the S1 protein. The antibodies will recognize the viral spike protein if the body is exposed to the virus and prevent COVID-19 illness. In animal studies, the immune response generated by the COVAC-1 vaccine was able to protect the vaccinated animals against a severe SARS-CoV-2 infection. The COVAC-005 Study is a Phase I, multi-centre trial of a SARS-CoV-2 vaccine booster. This is a randomized, observer-blinded, and placebo-controlled study to assess the safety and immunogenicity of COVAC-1 booster dose administered once in generally healthy adults 18-65 years of age who have received a minimum of 2 doses of an authorized COVID-19 vaccine at least 4 months prior to Day 0. The study will follow a dose-escalation design to test the safety and immunogenicity of three dosage levels (10, 25 and 50 µg). In each dose escalation group participants will be randomized in a 3:1 ratio, to receive either the investigational product or a placebo, respectively. Stratification will be according to the Investigational product dose received. Sub-analysis will be completed in two age groups, 18-54 and 55-65 years. Study participants will be initially randomized to the lowest dose of 10 µg or placebo. After approval by the Sponsor and based on the recommendations from the DSMB following the Day 7 safety analysis, new study participants will be allowed to be randomized in the higher dose escalation group of 25 µg. Approval will also be sought from the Sponsor, based upon the DSMB recommendation, to proceed with the higher dose of 50 µg. Within each dose escalation group of 16 participants (12 active vaccine recipients, and 4 placebo recipients) it is proposed to randomize a first cohort of 4 participants, including at least 3 active vaccine recipients, and pending no holding rule is met after 48 hours, as determined by the post-injection phone call, the remaining 12 participants within that dose escalation group will be randomized.

The aim of the CORONA.BOT project is to exploit the Artificial Intelligence methods of Generator Real World Data Facility to automatically extract structured and unstructured data from hospital databases and to implement an early risk assessment (warning system) regarding the negative outcome for patients infected with SARS-CoV-2. The objective of CORONABED.BOT is to analyze the care pathways of patients from the same cohort as CORONA.BOT, in order to identify the total length of stay, intensive care occupations and flows between departments, based on variables demographics and first entry clinics Early identification of patients with symptoms compatible with SARS-CoV-2 infection will enable more rapid activation of isolation procedures, contact monitoring/contact history and decisions on the most appropriate clinical pathway in terms of type of treatment and unit. Similarly, the identification of factors correlated with worse outcomes will allow more effective planning for the use of critical resources (such as intensive care and others).

Acute treatment of COVID-ARDS with direct topical lung instilled T3 therapy for patients on mechanical ventilation.

The aim of the study is to compare two methods of oxygen therapy in patients with acute respiratory distress syndrome in the course of SARS-CoV2 pneumonia. The initial method of oxygen supply during coronavirus pneumonia is conventional oxygen therapy using a face mask or nasal cannula. However, there have been reports in the literature that early initiation of high-flow oxygen therapy with a nasal cannula is associated with better prognosis. The study we perform is intended to provide reliable evidence for confirmation this hypothesis.
