Active clinical trials for "COVID-19"

Randomized, controlled study conducted in hospitalized patients with severe COViD-19 pneumonia and coagulopathy not requiring invasive mechanical ventilation. Aim of this study is to assess whether high doses of Low Molecular Weight Heparin (LMWH) (ie. Enoxaparin 70 IU/kg twice daily) compared to standard prophylactic dose (ie, Enoxaparin 4000 IU once day) are: More effective to prevent clinical worsening, defined as the occurrence of at least one of the following events, whichever comes first, during hospital stay: Death Acute Myocardial Infarction [AMI] Objectively confirmed, symptomatic arterial or venous thromboembolism [TE] Need for either non-invasive - Continuous Positive Airway Pressure (Cpap) or Non-Invasive Ventilation (NIV) - or invasive mechanical ventilation for patients who are in standard oxygen therapy by delivery interfaces at randomisation Need for invasive mechanical ventilation for patients who are in non-invasive mechanical ventilation at randomisation Similar in terms of major bleeding risk during hospital stay

Systemic medical ozone has proved to help in several viral diseases, chronic obstructive pulmonary disease and chronic inflammation process. The investigators are sure that its application to COVID-19 patients, as an adjuvant therapy, will improve the health status of these individuals.

The global pandemic of novel coronavirus disease 2019 (COVID-19) caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) began in Wuhan, China, in December 2019, and has since spread worldwide.1 As of April 14, 2020, there have been more than 1.5 million reported cases and 124 000 deaths in more than 200 countries. A recent open-label nonrandomized French study reporte that addition of azithromycin to hydroxychloroquine in 6 patients resulted in numerically superior viral clearance (6/6, 100%) compared with hydroxychloroquine monotherapy (8/14, 57%) or control (2/16, 12.5%). Azithromycin alone has never been tested, whereas azithromycin has immunomodulating and anti-inflammatory properties that could theoretically prevent or limit secondary worsening. Our hypothesis is that azithromycin combined with amoxicillin/clavulanate will be superior to amoxicillin/clavulanate alone to obtain viral clearance at Day 6 in COVID-19 patients with pneumonia and hospitalized in a non-intensive care unit ward.

The present study is a randomized, double-blind, controlled, clinical trial, with the approval of the ethics committee will be conducted on patients who have a positive test confirming COVID-19 in Shahid Modarres Medical Education Center and Hospital in Tehran. Patients will be randomly assigned to the two arms of the study and after completing the course of treatment and collecting and analyzing the necessary information from each patient, the results of the study will be published both on this site and in the form of an article in a reputable international journal.

The present study will try to respond first in an initial phase, what is the minimum effective dose necessary of convalescent plasma for getting better in severly ill (not intubated) or very severely ill (intubated) patients. Once the dose will be determined by each type of patient group (severely ill vs. very severely ill) has been determined, phase 2 of the study will begin, where the safety and efficacy of the use of plasma will be evaluated based on clinical, imaging and laboratory criteria. So, our hypotheses are: Is there a minimum effective dose to treat seriously ill patients with convalescent plasma with COVID-19? the plasma dose with the minimum effective effect will improve the clinical, laboratory and clearance conditions of the presence of the virus in the severely ill patient?

The main objective of this study is to assess the efficacy of the combination hydroxychloroquine and Azithromycin (HCQ and AZ) in reducing the infection risk among health care professionals in direct contact with COVID-19 patients.

Captopril being an effective drug available in liquid preparation, administration by nebulization could be of interest for maximizing lung action and minimizing systemic side effects. Such a treatment might be used for "Covid-19" patients with pneumonia in order to avoid ARDS.

This clinical study is the first clinical study in literature (submitted on 20 April, 2020) which demonstrated that Isotretinoin will provide complete protection against COVID-19 Abstract The COVID-19 pandemic caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) has infected over 100 million people causing over 2.4 million deaths over the world, and it is still expanding. There is an urgent need for targeted and effective COVID-19 treatments which has put great pressure on researchers across the world for developing effective drugs. In this clinical study we attempt to demonstrate Isotretinoin could be an effective and promising treatment for SARS-CoV-2 based on the intracellular mechanism of SARS-CoV-2 transmission and consequences caused. Isotretinoin could strongly inhibit both inflammation and viral entry in severe acute respiratory syndrome coronavirus 2 infection via decreasing the overproduction of early response proinflammatory cytokines (interleukin-6 ) which are over expressed in COVID-19 and contributed to disease progression, poor outcomes, vascular hyper permeability and multiorgan failure in patients infected with COVID-19. It could also block the entry of COVID-19 by inhibiting androgenic factors that induce serine 2 transmembrane protease (TMPRSS2) expressions.. In addition to inhibiting of Angiotensin-converting enzyme-2 (ACE2), Angiotensin T1 protein and Angiotensin II-mediated intracellular calcium release pathway which is responsible for COVID-19 cell fusion and entry, ACE2-expressing cells are prone to SARS-CoV-2 infection as ACE2 receptor facilitates cellular viral entry and invasion. Moreover, isotretinoin is a potential repressor and inhibitor of papain-like protease (PLpro), which is a lethal protein expressed by COVID-19 genes and is an enzyme of dubiquitination which facilitates virus replication in patients with COVID-19.The genome of Middle East Respiratory Syndrome Coronavirus is recognized by melanoma differentiation-associated protein-5 (MDA5), retinoic acid inducible gene-1 (RIG-1) and endosomal toll-like receptor 3 (TLR3) as pathogen-associated molecular patterns. This recognition resulted in the formation of type-1 interferon (IFN1). As an evasion mechanism, virus synthesize proteins that hinder the production IFN1 in the pathway. 13-cis retinoic acid induced significant upregulation of toll-like receptor 3 (TLR3), mitochondrial antiviral-signaling protein (MAVS) and IFN regulatory factor 1 expression in a time-dependent. Furthermore, 13 cis Retinoic Acid (13 cis RA) could be an effective and promising treatment for SARS-CoV-2 owing to its ability to increase CD4 cells and induce mucosal IgA antibodies that are less prone to Antibody Dependent Enhancement process (ADE) and responsible for passive mucosal immunity in the respiratory tract. ADE is a phenomenon in which antiviral antibodies facilitate viral infection of target immune cells and, in some cases, make a second infection worse, such as dengue fever (dengue virus), By inducing IgA antibodies, 13 cis retinoic acid enhances mucosal immunity and is known to be a potent IgA isotype.13 Cis retinoic acid induced significant upregulation of toll-like receptor 3 an immune boosting action that may result in an immune response to dsRNA intermediate leading to the production of type I IFNs which is important to enhance the release of antiviral proteins for the protection of uninfected cells. Isotretinoin therapy has furthermore proven anti-platelet and fibrinolytic activities which may protect patients infected with covid-19 from widespread blood clots. From this point, we suggest that isotretinon will be the Immunity passport" in the context of COVID-19

The purpose of this trial is to determine whether Prone Positioning (PP) improves outcomes for non-intubated hospitalized patients with hypoxemic respiratory failure due to COVID-19, who are not candidates for mechanical ventilation in the ICU. The investigators hypothesize that PP will reduce in-hospital mortality or discharge to hospice, compared with usual care for non-intubated patients with do-not-intubate goals of care with hypoxemic respiratory failure due to probable COVID-19.

The overall objective is to evaluate the clinical efficacy and safety of tocilizumab relative to placebo among approximately 300 hospitalized adult patients who have severe COVID-19. The study will be a 2 arm double blinded comparison between tocilizumab 8 mg/kg and matching placebo IV. The dose may be repeated in 8-12 hours if clinical symptoms worsens, (e.g. increase in oxygen requirements). Participants will be followed for 28 days.
