View clinical trials related to Covid19.
Filter by:There are currently no antiviral drugs with proven efficacy nor are there vaccines for its prevention. Unfortunately, the scientific community has little knowledge of the molecular details of SARS-CoV-2 infection. The drugs we are chosen are used as clinical trials for antiviral and there is no proven guide for specificity and effectiveness against the virus so the results are different Now the clinical trials and research authorities are work speedily to target the most proven treatment for the virus so anything is infantile until now. the covid-19 with time be more explained by scientists it is steroid response disease and cause thromosis and cytokine storm , the aim of the study to inhibit viral replication and decrease the severity of the disease as antiviral and anticytokine storm , antithrombosis Zinc is a mineral element needed to regulate adaptive immune cells' functions. Higher level of intracellular zinc showed to increase intracellular pH; which affect on RNA-dependent RNA polymerase and decrease replication mechanism of RNA viruses. Therefore, drugs that described as zinc ionophores could be used with zinc supplement to act as antiviral against many RNA viruses including SARS-CoV-2 Quercetin is natural compound act as zinc ionophore to cause zinc influx intracellular. Quercetin is a safe natural anti-oxidant and anti-inflammatory polyphenolic compound that found in various natural sources include onion, red grapes, honey and citrus fruits. It was shown that quercetin has the ability to chelate zinc ions and act as zinc ionophore. Therefore, quercetin could have antiviral activity against many RNA viruses . Quercetin, a flavonoid found in fruits and vegetables, has unique biological properties that may improve mental/physical performance and reduce infection risk ; These properties form the basis for potential benefits to overall health and disease resistance, including anti-carcinogenic, anti-inflammatory, antiviral, antioxidant, and psychostimulant activities, as well as the ability to inhibit lipid peroxidation, platelet aggregation and capillary permeability, and to stimulate mitochondrial biogenesis .There are various studies that report the immunomodulatory effect of bromelain . Bromelain activates natural killer cells and augments the production of granulocyte-macrophage-colony stimulating factor, IL-2, IL-6 and decreases the activation of Thelper cells. Thus, bromelain decreases the majority of inflammatory mediators and has demonstrated a significant role as an anti-inflammatory agent in various conditions Vitamin C is known as an essential anti-oxidant.,and enzymatic co-factor for physiological reactions such as hormone production, collagen synthesis and immune potentiation . Naturally, an insufficiency of vitamin C leads to severe injuries to multiple organs, especially to the heart and brain, since they are both highly aerobic organs that produce more oxygen radicals. In fact, studies of in vivo effect on vitamin C are difficult since most animals, except human and some primate, are capable of synthesizing vitamin C endogenously
A key strategy in the treatment of COVID-19 would be to find an effective antiviral agent that would decrease the peak viral load and, consequently, the associated degree of immunopathological damage that follows this phase. The clinically approved substances considered for this study are used for treatment of other virus diseases, like HIV (atazanavir) and HCV (sofosbuvir and daclatasvir). Severe progression of COVID-19 among patients under treatment for these aforementioned viruses is empirical less common. Besides, the clinical rationale, there are pre-clinical evidence pointing out that patients with COVID-19 could benefit from treatments with atazanavir, sofosbuvir and daclatasvir.
The new coronavirus pandemic responsible for the severe acute respiratory syndrome SARS-CoV2 requires, in its severe forms, the use of invasive ventilation in intensive care. The first patients seen in intensive care presented with neurological symptoms and usually not seen in non-viral ARDS or due to other viral causes. These were mainly restless awakenings, attempts at self-extubation and confusional syndromes. Although the data in the literature do not seem to reveal the presence of SARS-CoV2 in the CSF of these patients, certain elements seem to show parenchymal brain damage with the description of hypometabolism of the frontal regions. In addition, most of these patients present a memory complaint after going into intensive care (personal data not published). We do not know to date what is the cognitive and psychic profile of these patients, nor what will be their future evolution. Some patients may require specific neuro-cognitive rehabilitation. The aim of this study is to assess the cognitive profile of patients infected with COVID-19 who have used invasive ventilation in the intensive care unit of Paris Saint-Joseph hospital since April 2020, in order to be able to compare them between them and follow their evolution in the medium term. This work could make it possible to describe the specific cognitive impairment of SARS-CoV2, by trying to evade other causes of cognitive disorders in patients hospitalized in intensive care for respiratory distress (hypoxia, treatments, metabolic disorders, etc.). The main objective is to follow the medium-term evolution between 3 and 6 months of the cognitive profile of patients with severe form of SARS-CoV2 with the use of ventilatory resuscitation.
This study aims to collect convalescent plasma and use it as experimental treatment in critically ill Covid-19 patients in order to reduce mortality and length of stay in intensive care unit.
Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), the virus responsible for COVID-19, enters type II pneumocytes using angiotensin-converting enzyme 2 (ACE2). It is unclear whether ACE inhibitors (ACEIs) and angiotensin receptor blockers (ARBs) increase, decrease, or have no significant effect on ACE2 expression or activity. Therefore, ACEI and ARB may be harmful, beneficial, or have no impact on Coronavirus Disease 2019 severity and mortality. The Specific Aims of this observational study are: (1) Among SARS-CoV-2-positive outpatients, compare all-cause hospitalization and mortality rates between: 1.1 Current users of a range of doses of ACEI/ARB- vs. non- ACEI/ARB-based regimens, and 1.2 Current users of a range of doses of ACEI- vs. ARB-based regimens, and (2) Among those hospitalized for COVID-19, compare all-cause mortality between: 2.1 Current users of a range of doses of ACEI/ARB- vs. non- ACEI/ARB-based regimens, and 2.2 Current users of a range of doses of ACEI- vs. ARB-based regimens.
The aim of this work is to conduct a randomized, double-blind, placebo-controlled clinical trial to assess the efficacy and safety of cannabidiol (CBD - 300 mg a day) in patients infected with SARS-CoV-2. The specific objectives are to assess whether, in patients with mild and moderate forms of SARS-CoV-2, daily use of CBD 300 mg for fourteen days is capable of: i) decrease viral load; ii) modify inflammatory parameters, such as cytokines, measured from serum; iii) reduce clinical and emotional symptoms through daily clinical evaluation; iv) improve sleep; v) reduce hospitalization and worsen the severity of the disease; v) Monitor the possible adverse effects of CBD use in these patients.
A phase 2/3 multi-center randomized, double-blind, parallel arm, placebo- controlled study in Adult Subjects Hospitalized with Severe SARS-CoV-2 Positive Pneumonia to determine the potential of opaganib to improve and/or stabilize the clinical status of the patient.
The purpose of this study is to assess the efficacy and safety of the administration of anti-SARS-CoV-2 convalescent plasma in COVID-19 patients who are sick enough to warrant hospitalization, but not yet admitted to the ICU (prior to the onset of overwhelming disease including a systemic inflammatory response, sepsis, and/or ARDS).
This study aims to evaluate several of Owlstone Medical's Breath Biopsy aerosol respiratory droplet capture techniques for the detection of nCOVID-19. These are single use disposable breath capture devices with removable filters and fitted PVA strip that directly sample exhaled breath aerosols and therefore, directly sample the primary transmission route for the virus. They can be used independently and shipped for analysis for the presence of nCOVID-19 using established existing assays available in any reference lab. The trial is a non-inferiority trial comparing diagnostic accuracy of collection via face mask vs. available diagnostic procedures in standard care and will also asses the feasibility of patient use of the equipment. Subjects will be recruited at the Addenbrookes Hospital, Cambridge. Minimal patient characteristics (e.g. age, sex) are collected. Between 20 and 100 subjects with with a positive nCOVID-19 diagnosis will be sampled to obtain to address the primary study hypothesis. Due to the pre-test probability of patients being positive for nCOVID-19 is unknown we will monitor the number of sampled subjects with a positive diagnosis on a weekly basis. The clinical diagnosis of the subject based on a combination of imaging, viral diagnostics and clinical assessment will be used as the reference standard. When this number hits 100 the study will be discontinued. In total no more than 500 subjects shall be sampled in this trial.
The COVID-19 pandemic has led to shortages of intravenous sedatives due to increased ICU patient admissions and greater use of mechanical ventilation. A shortage of sedatives is as concerning as a shortage of mechanical ventilators since critically ill patients require sedation for comfort and to tolerate mechanical ventilation. Anti-adrenergic medications are increasingly recognized for their role in sedation of critically ill patients. Propranolol is a plentiful and inexpensive, non-selective beta-adrenergic blocker with good penetration of the blood-brain barrier, which can reduce agitation and arousal. The study team published a single-centre retrospective study of 64 mechanically-ventilated patients which found the initiation of propranolol was associated with an 86% reduction in propofol dose and a roughly 50% reduction in midazolam dose while maintaining the same level of sedation. Propranolol has the potential to mitigate the threat posed by worldwide sedative shortages and improve critical care management of patients who require mechanical ventilation. This study seeks to evaluate whether the addition of propranolol to a standard sedation regimen reduces the dose of sedative needed in critically ill patients requiring mechanical ventilation. This study is an open-label randomized controlled trial, single-blinded with 1:1 allocation. Both arms will receive sedation according to usual intensive care unit practice with a sedative agent. The intervention arm will additionally receive enteral propranolol 20-60mg q6h titrated up over 24-48h until intravenous sedative doses have fallen to a minimal level (propofol <0.5mg/kg/h or midazolam <0.5mg/h) or the maximum dose of propranolol is reached. Intravenous sedative doses will be titrated downwards in response to sympatholysis produced by the propranolol, as evidenced by a decreasing heart rate or blood pressure. The control arm will receive sedation without the addition or propranolol. The primary outcome will be the change in primary sedative dose from baseline to Day 3 of enrollment. Analysis of the primary outcome will be a difference in differences; the change in sedative dose from baseline to Day 3 in the intervention group versus the same change in the control group. The Mann-Whitney U test will be used as a nonparametric test of independent samples for this outcome.
