Filter by:Phase 1b, multi-center, open label, sequential dose escalation trial assessing 3 dose cohorts using a 3+3 design to evaluate safety and tolerability of Allocetra-OTS in adult patients with moderate COVID-19. The sample size for this trial is anticipated to range from 9 to 18 patients.
This is a randomized, double-blinded, placebo controlled phase III clinical trial to evaluate the efficacy, safety and immunogenicity of SARS-CoV-2 Vaccine, Inactivated (Vero Cell) in adults aged 18 years and above after 2-dose schedule.
COVID-19 infection causes a hypersensitive immune reaction and widespread inflammation through cytokines in various organs of the body, especially the lungs. This cytokine-mediated widespread inflammation can also affect the thyroid gland, causing thyroiditis and impaired thyroid functions. The researchers evaluated thyroid function tests and thyroid autoantibodies in patients hospitalized for COVID-19 infection. Researchers excluded patients on intensive care therapy and patients with known thyroid disease. The researchers examined the relationship of thyroid hormones and thyroid autoantibodies to COVID-19 disease, white blood cells, neutrophil / lymphocyte ratio, c reactive protein, fibrinogen, procalcitonin, ferritin, and D-dimer stages in these patients. Researchers compared changes in thyroid hormones and autoantibodies in people without COVID-19 infection and without thyroid disease.
This is a multicenter, observational, prospective, epidemiological cohort study at 45 hospitals in Germany, all part of a German hospital network. All hospitalized patients tested positive for SARS-CoV-2 will be included.
The purpose of this study is to determine if an investigational drug, AT-100, is safe and tolerated by adults who have severe corona virus disease 2019 (COVID-19) or respiratory failure secondary to severe community acquired pneumonia.
A randomized, double blind, multicenter, placebo-controlled, parallel group, fixed dose, phase II study to evaluate the efficacy and safety of glenzocimab in ARDS.
The Renin-Angiotensin-Aldosterone System (RAAS) is involved in blood pressure regulation and electrolyte balance. Angiotensin-converting enzyme (ACE) is a critical regulator of RAAS by cleaving angiotensin (Ang1) to Angiotensin2 (Ang2), which is the most powerful biologically active product of RAAS [1]. In the same context, angiotensin-converting enzyme 2 (ACE2) converts Ang2 to Ang (1-7), which is a vasodilator, antithrombotic, and antihypertrophic peptide [2]. ACE2 which is found in many tissues [3] has opposite effects to ACE on the heart, kidneys, and lungs [4]. Many pathological conditions, in particular cardiovascular disease (CVD), have shown a link between a disturbance in ACE/ACE2 ratio and the downregulation of ACE2 levels [5]. Also, ACE/ACE2 has been reported to be higher in moderate to severe chronic heart failure [6] as well as systolic blood pressure [7]. Recently, an elevated ACE/ACE2 ratio is linked to Coronavirus disease 2019 (COVID-19). SARS-COV2 enters target cells by binding of the spike protein to ACE2 and a specific transmembrane serine protease 2 (TMPRSS2) for the spike (S) protein priming, which also leads to downregulation of ACE2 [8]. Down-regulation of ACE2 caused by Coronavirus may have a potential role in the pathogenesis of COVID-19 infection. Accordingly, people with a higher ACE/ACE2 ratio may be more at increased risk of worse Covid-19 consequences [9]. On the other hand, omega-3 fatty acids could decrease CVD risk by their anti-inflammatory anti-thrombotic function [10]. A meta-analysis comprising 15,806 patients, showed that omega-3 fatty acids associated with a 30% reduction in fatal myocardial infarction and sudden death, in addition to a 20% reduction in overall mortality [11]. To the best of our knowledge, no clinical trials have evaluated the effect of omega-3 supplementation on serum ACE/ACE2 ratio which is recently ascribed as a potential key in 2019 Covid-19 as well as CVD [5,9].
The COVID-19 Prevention Network (CoVPN) is doing a study to estimate the number of people who have or have had the SARS-CoV-2 virus in different communities in the United States. This study is being done to help determine the best places to perform future research studies that will test new drugs for treatment or prevention of COVID-19.
Retrospective cohort study comparing the early prognosis after surgically-treated proximal femur fragility fractures in patients affected and not affected by COVID-19.
To assess the efficacy and safety of FOY-305 in patients with SARS-CoV-2 infection (COVID-19) in a placebo-controlled, multicenter, double-blind, randomized, parallel-group comparative study.
