Active clinical trials for "Coronavirus Infections"

This is a randomized, double-blind, placebo-controlled, multicenter, 28-day study of adult participants hospitalized with COVID-19, with a safety follow-up telephone call at Day 60.

In December 2019, a group of patients with pneumonia of unknown cause was linked to a wholesale seafood market in Wuhan, China. The genetic analysis of samples from the lower respiratory tract of these patients indicated a new coronavirus as the causative agent, which was named SARS-CoV-2. The virus spread rapidly to more than 45 countries, including Brazil, causing an international alarm. However, in spite of its epidemiological magnitude, so far, there is no antiviral treatment or vaccine approved for the treatment of this infection. With about 15% to 20% of SARS-CoV-2 patients suffering from serious illnesses and overburdened hospitals, therapeutic options are desperately needed. So, instead of creating compounds from scratch that can take years to develop and test, researchers and public health agencies have sought to redirect drugs already approved for other diseases and known to be widely safe. In this context, the analysis of the international literature shows the existence of an in vitro antiviral activity of ivermectin against SARS-CoV-2. However, there are no studies that have evaluated its clinical effectiveness in patients diagnosed with SARS-CoV-2 infection. Therefore, and considering this knowledge gap, the present study aims to determine the clinical efficacy and safety of different doses of ivermectin in patients diagnosed with SARS-CoV-2 infection.

Treatment with glucocorticoids in COVID patients. Low-intervention, phase IV, open-label, randomised, low-intervention clinical trial comparing 2 active treatments.

The COVID-19 coronavirus has led to a global pandemic of respiratory diseases with an increase in hospitalization and death risk. To keep COVID-19 manageable for healthcare, early treatment is urgently needed to avoid hospitalization. Dexamethasone can dampen the exaggerated cytokine response to COVID-19 and is a promising agent for preventing disease aggravation, hospitalization and death. However, the evidence on the effectiveness, safety and cost-effectiveness of dexamethasone treatment in primary care is inconclusive.

SARS-CoV-2 is a member of a class of viruses: angiotensin converting enzyme 2 (ACE2)-binding viruses that study calls "ABVs". The World Health Organization (WHO) and others are performing randomized controlled trials (RCTs) of vaccines and novel antivirals to address SARS-CoV-2 directly. However, the critical illness complications of COVID-19 are caused in part by SARS-CoV-2's binding and inhibiting ACE2 and the consequent host response. ACE 2 is the receptor for H1N1, H5N1, and SARS-CoV-2. After binding ACE2, SARS-CoV-2 is endocytosed, and surface ACE2 is down-regulated, increasing angiotensin II (ATII a potent vasoconstrictor) in COVID-19. The original ARBs limits lung injury in murine influenza H7N9 and decreases viral titre and RNA. Study has a unique opportunity to complement vaccine and anti-viral RCTs with an RCT modulating the host response using an angiotensin II type 1 receptor blocker (ARBs) to decrease the mortality of hospitalized COVID-19 patient.

This multi-center, open-label, 2 arm parallel-group, randomized, interventional prospective exploratory study in 40 patients aimed to evaluate safety and explore putative clinical benefits of Silmitasertib 1000 mg BID dose in patients with severe illness caused be SARS-COV-2. This will be a two-arm trial comparing the SOC/best supportive care alone to the SOC/best supportive care with addition of Silmitasertib (allocation ratio 1:1).

The emergence & rapid spread of the coronavirus disease 2019 (COVID-19) since December 2019 across 188 countries globally has become a major public health crisis. COVID-19 was declared a pandemic by the World Health Organisation on 11 March 2020. To date, tens of millions of cases have been reported and over 3% of these cases have died. COVID-19 is an acute respiratory disease caused by the novel SARS-CoV-2 virus from the Betacoronavirus genus, just like SARS-CoV and MERS-CoV. SARS-CoV-2 is primarily transmitted person-to-person through respiratory droplets/close contact. Fomite transmission has also been shown as a transmission route. Common respiratory symptoms such as fever, sore throat, cough & shortness of breath, may appear 2 - 14 days after exposure. About 20% of infected cases progress to severe disease resulting in an estimated 2 - 5% mortality rate. With the unrelenting increase in cases being reported worldwide, there is thus an urgent need for therapeutics to be developed to treat disease & reduce further transmission in order to disrupt the ongoing pandemic. To date, there are no specific proven antiviral treatment to prevent disease progression from mild to severe respiratory dysfunction among COVID-19 patients. Supportive care is recommended for symptom relief & for severe cases. Numerous vaccine candidates against SARS-CoV-2 are under development. Tychan's TY027, a fully engineered human IgG, is one of the first few biologics in the world, specifically targeting SARS-CoV-2, to enter human clinical trials. Preliminary data from our phase 1 healthy volunteer trial (SCT-001; ClinicalTrials.gov Identifier NCT04429529) reveals that TY027 is safe & well-tolerated up to 20 mg/kg tested. A total of 10 adverse events (AEs) were observed, all were of mild in intensity with none resulting in subject withdrawal from the study. There were no serious adverse events & no clinically relevant trends in mean clinical laboratory, physical examinations, vital signs or ECG results were observed. Pharmacokinetic profile of subjects across dose cohorts 1 - 4, up to Day 14, were comparable to those typical of human IgG1 antibody with serum concentrations declining in a biphasic manner. Exposure of TY027, based on Cmax, increased in a linear & generally dose proportional manner. It is anticipated that TY027, when administered to acutely infected COVID-19 patients, could reduce disease severity. It may potentially also be used as a prophylaxis against COVID-19 amongst high risk contacts.

Our hypothesis is that treating ARDS caused by COVID-19 with bevacizumab improves mortality. This is a phase II, multi-centered, randomized, open label, two-armed clinical trial to study the safety and efficacy of bevacizumab in COVID-19 positive patients who consequently developed ARDS (acute respiratory distress syndrome) and who have previously received anti-viral and anti-inflammatory treatment.

to identify the diagnostic accuracy of chest X-ray in diagnosis of Coronavirus disease19 .

This was a Phase 2, randomized, double-blind, placebo-controlled, parallel-group, multicenter, dose escalation and proof-of-concept study to evaluate the safety and efficacy of razuprotafib, administered 3 times daily (TID) (every 8 hours [Q8H]), in hospitalized subjects with moderate to severe Coronavirus disease 2019 (COVID-19) receiving standard of care therapy. The study was planned to include 2 parts with Part 1 comprising the dose escalation period of the study and Part 2 comprising the proof-of-concept safety and efficacy period of the study.
