Active clinical trials for "Coronavirus Infections"

We aim to better understand the mode of action of COVID-19 in the context of its interaction with the host genome through whole-genome sequencing.

Severe acute respiratory syndrome (SARS) coronavirus 2 (CoV 2) (COVID19) is a readily transmissible virus that has a wide ranging incubation period of 2-14 days. The symptoms include fever, cough and loss of taste and smell. Symptoms range from mild to severe. Pre-existing potential drug therapies are under investigation, but so far few have demonstrated any benefit and only in patients with severe symptoms. There is a scarcity of other pre-existing drug treatments that change the outcomes/symptoms in non-hospitalised patients with COVID-19. Prophylaxis and prevention is currently dependent on social distancing and isolating with vaccines remaining in development, potentially not for mass use in the near future. Sambucus extract has well documented anti-viral properties both in vitro and in clinical trials of influenza, it has a low side effect profile so may be effective in reducing duration of symptoms and progression to more severe disease in patients with mild/ moderate COVID19. Black Elderberry Original Liquid (Sambucus nigra) (Sambucol®) is sold as a food supplement in heath food shops and supermarkets, does not require a prescription and has no known side effects, meaning it would be a well-tolerated treatment in early disease in comparison with other potential medications. The study will be conducted at East Kent Hospitals. Potential participants with mild or moderate confirmed COVID19 infection will be identified from the drive-through hospital test centre and accident and emergency. Following an eligibility check and consenting they would be randomised to placebo or Sambucol® Black Elderberry (Sambucus nigra) 15ml four times daily for 14 days which they will take at home. Telephone consultations with the research team and patient daily diaries will used to document symptoms on days 1,3,7,10,14 and a follow up on day 28. Time to clinical improvement will be compared between the 2 groups.

this study will be conducted to investigate the effect of Active Cycle Breathing Technique and incentive spirometer on COVID19 patient

The goal of this clinical trial is to examine the effectiveness of intranasal-administered Chlorpheniramine Maleate in COVID-19-positive participants as part of early treatment for COVID-19. The main questions it aims to answer are: To assess the efficacy of nasal spray with Chlorpheniramine (1.0%) for improving clinical recovery in COVID-19 patients. To assess the efficacy, safety, and tolerability of nasal spray with Chlorpheniramine (1%) as an adjunct to the standard of care in reducing hospitalizations and improving clinical recovery in adult patients with mild COVID-19.

Background: Middle East Respiratory Syndrome (MERS) is a newly discovered contagious and sometimes fatal respiratory virus. People often get MERS through close contact with an infected person. Scientists are worried that MERS may spread and cause more infections. There are no vaccines or treatments for MERS right now. Researchers think a new therapy called SAB-301 may be able to help. Antibodies are proteins the body makes to attack viruses. SAB-301 is made of antibodies made in cows to fight MERS. The antibodies are collected from plasma, the liquid part of cow blood. Objective: To evaluate the safety and tolerability of SAB-301 in healthy adults. Eligibility: Healthy people ages 18 60 who: Do not have chronic medical problems Do not take any medications (exceptions are acetaminophen, ibuprofen, vitamins, seasonal allergy meds and oral contraception) Do not have allergies to beef products Agree to use two forms of contraception while on study (both men and women) Design: Participants will be screened with: Medical history Physical examination Blood and urine tests Participants will have a return visit. They will have a physical exam and blood tests. They will be randomly assigned to receive either SAB-301 or a placebo which is given by infusion through an arm vein over 1 3 hours. They will be monitored at the clinic for 6 hours after the infusion. They will have additional blood draws. Participants will have 2-hour visits 1, 3, 7, 21, 42, and 90 days after the infusion. At each visit they will be evaluated and have blood and urine tests.

COVID-19 caused clusters of severe respiratory illness and was associated with 2% mortality. No specific anti-viral treatment exists. The mainstay of clinical management is largely symptomatic treatment, with organ support in intensive care for seriously ill patients. Cellular therapy, using mesenchymal stem cells has been shown to reduce nonproductive inflammation and affect tissue regeneration and is being evaluated in patients with ARDS. This clinical trial is to inspect the safety and efficiency of mesenchymal stem cells (MSCs) therapy for severe COVID-19.

Facing the challenge of finding an efficient treatment for COVID-19, the viral pneumonia caused by the Coronavirus SARS-Cov-2, this study intended to test if Chloroquine or Hydroxychloroquine, two drugs with strong in-vitro antiviral role proven by numerous studies and with a well defined safety profile established, for efficacy in treating COVID-19 and improving an ordinal primary outcome composed by a 9-levels scale, which was recomended by the World Health Organization.

In adults with COVID-19 without criteria for hospitalization or oxygen therapy but with risk factors for aggravation, early treatment may avoid hospitalization, indication for oxygen therapy or death. No treatment is currently validated for this indication.

Coronavirus (COVID-19) is a somewhat new and recognized infectious disease that is now spreading to several countries in the world, including Brazil. Hydroxychloroquine and azithromycin may be useful for treating those patients. COALITION I study aims to compared standard of care, hydroxychloroquine plus azithromycin and hydroxychloroquine monotherapy for treatment of hospitalized patients with COVID-19. COALITION I will recruit 630 patients with infection by COVID-19 (210 per arm). Ordinal endpoint of status at 15 days will be the primary endpoint.

Cytokines and chemokines are thought to play an important role in immunity and immunopathology during virus infections [3]. Patients with severe COVID-19 have higher serum levels of pro-inflammatory cytokines (TNF-α, IL-1 and IL-6) and chemokines (IL-8) compared to individuals with mild disease or healthy controls, similar to patients with SARS or MERS . The change of laboratory parameters, including elevated serum cytokine, chemokine levels, and increased NLR in infected patients are correlated with the severity of the disease and adverse outcome, suggesting a possible role for hyper-inflammatory responses in COVID-19 pathogenesis. Importantly, previous studies showed that viroporin E, a component of SARS-associated coronavirus (SARS-CoV), forms Ca2C-permeable ion channels and activates the NLRP3 inflammasome. In addition, another viroporin 3a was found to induce NLRP3 inflammasome activation . The mechanisms are unclear. Colchicine, an old drug used in auto-inflammatory disorders (i.e., Familiar Mediterranean Fever and Bechet disease) and in gout, counteracts the assembly of the NLRP3 inflammasome, thereby reducing the release of IL-1b and an array of other interleukins, including IL-6, that are formed in response to danger signals. Recently, colchicine has been successfully used in two cases of life-threatening post-transplant capillary leak syndrome. These patients had required mechanically ventilation for weeks and hemodialysis, before receiving colchicine, which abruptly restored normal respiratory function and diuresis over 48 hrs [4].
