Filter by: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.
Viral respiratory infections are common infectious complications after kidney transplantation, especially in the pediatric age group, and immunosuppressed patients may develop more severe disease. Immunosuppressive medications alter the patient's immune response by acting on humoral, cellular immunity and neutrophil function, increasing the risk of serious viral infections. Little is known about how these patients respond to infection by the new coronavirus (SARS-CoV-2). Experience with SARS caused by the Influenza H1N1 virus suggests that the severity of the disease depends on pre-existing comorbidities and the individual immune response. In more severe cases, an imbalance between the inflammatory system and the immune system is observed, determining direct consequences when pro and anti-inflammatory cytokines reach the systemic circulation in an exacerbated and unbalanced manner. Such fact can generate "cytokine storm syndrome", resulting in multiple organ dysfunction syndrome. March 2020 reports from Papa Giovanni XXIII Hospital in Bergamo, Italy - one of the largest pediatric liver transplant centers - showed that the number of transplant patients infected with Coronavirus disease 2019 (COVID- 19) increased progressively. However, they did not see greater severity and complications in this population. Immunosuppression could act as a protective factor. The present study aims to describe the prevalence of viral infection by SARS-CoV-2 in a sample of immunosuppressed children, from three groups: kidney transplants, liver transplants and oncohematological. The investigators will also look for the epidemiological profile and clinical evolution of these patients, enabling a better understanding of the COVID-19 in this special population. The investigators' hypothesis is that infection with the new coronavirus may be asymptomatic in a large number of children and that immunosuppression, observed in liver and kidney transplant patients and also seen in cancer patients, may act as protection for severe forms of COVID-19. After obtaining written informed consent from the family, the investigators will include patients from 0-18 years of age, on regular outpatient follow-up, symptomatic or not, and will check for the presence of IgM/IgG antibodies against the SARS-CoV-2. For those symptomatic or with a positive IgM result, material (oro/nasopharyngeal swabs) for RT-PCR trial for the new coronavirus will be collected. Demographic and clinical variables will be registered. The outcomes are: Serology for COVID-19 result; PCR for COVID-19 result; presence of symptoms of COVID-19; proportion of patients with viral shedding on days 3,7,14,21 and 30 after diagnosis; need for hospital admission; need for Intensive care admission; death.
Rationale: The renin-angiotensin-aldosterone system (RAAS) dysregulation may play a central role in the pathophysiology of Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2) infection associated acute lung injury (ALI) / acute respiratory distress syndrome (ARDS). In the RAAS, Angiotensin I (Ang I) is converted to angiotensin II (Ang II) by angiotensin converting enzyme (ACE). Ang II mediates vasoconstrictive, pro-inflammatory and pro-oxidative effects through agonism at Ang II type 1 receptor (AT1R). ACE2 converts Ang II to angiotensin 1-7 (Ang1-7), which finally binds to Mas receptor (MasR) and mediates many beneficial actions, including vasodilation and anti-inflammatory, anti-oxidant and antiapoptotic effects. ACE2, a homologue of ACE, is an integral cell membrane protein with a catalytic domain on the extracellular surface exposed to vasoactive peptides. SARS-CoV-2 penetrates the cell through ACE2, and the increase of this receptor (due to the use of ACE inhibitors or angiotensin receptor blockers [ARBs]) may facilitate SARS-CoV-2 infection, which might increase the risk of developing severe and fatal SARS-CoV-2 infection. However, through upregulation of ACE2, ACE inhibitors/ARBs can exert anti-inflammatory and antioxidative effects, which may be beneficial in preventing ALI and ARDS. Objective: To evaluate the effectiveness and safety of telmisartan in respiratory failure due to COVID-19. Study design: This is an open label, phase 2 clinical trial. Study population: Adult hospitalized SARS-CoV-2-infected patients (n=60). Intervention: The active-treatment arm will receive telmisartan 40 mg daily and the control arm will receive standard care. Treatment duration will be 14 days or up to hospital discharge <14 days or occurrence of the primary endpoint if <14 days. Main study endpoint: The primary study endpoint is the occurrence within 14 days of randomization of either: 1) Mechanical ventilation or 2) Death.
The coronavirus (COVID-19) pandemic continues to grow exponentially. Angiotensin II levels are increased in human influenza and are associated with influenza viral load, disease progression and mortality. Preliminary data shows angiotensin II receptor blockers (ARBs) limits lung injury in murine influenza H7N9, as well as viral titre and RNA. ARBs could limit viral titre and organ injury in COVID-19. We will therefore collect clinical chart data and test angiotensin II levels of patients who are admitted to ICU with COVID-19 to determine whether there is a correlation between taking ARBs and clinical outcomes in these patients. Other blood biomarkers and clinical risk factors for COVID-19 have come to light in recent weeks. We include these in our observational analysis to help generate an understanding of COVID-19 presentation and blood biomarker characterization of disease.
this observational, cross-sectional, national, comparative study, including RMD patients followed in hospital centres of the FAI²R Rare Diseases Healthcare Pathway network and specialist private practitioners caring for patients suffering from inflammatory rheumatism, systemic autoimmune diseases and auto-inflammatory diseases. The objective of the study is to compare RMD patients with COVID 19 infection (cases) to RMD patients who have not had COVID 19 infection (controls) on their mental health.
Evaluation of the ddPCR ability to detect the SARS-CoV-2 in nasopharyngeal samples of symptomatic patients with suspected COVID-19 infection using an IgG serological assay (EUROIMMUN Anti-SARS-Cov2 ELISA Ig) as gold/reference standard (FDA validated commercial serologic test).
Title: Phase I/II Trial (Safety and Dosing) of Povidone-iodine (PVP-I) Nasal Swab For Preventing COVID-19 Spread in Healthy Subjects: Summary: This study will evaluate in a PH I/II trial in healthy volunteers the safety and tolerability of PVP-I nasal swabs daily application. The intent is to follow with a PH III randomized controlled clinical trial to assess the capacity for PVP-I nasal swabs to mitigate the transmission of respiratory viruses specifically COVID 19.
The global escalation of COVID19 pandemic has put the health care system under pressure with urgent need for treatment. In the absence of vaccine and approved drug against SARS-COV2 over the past 6 months, the health authorities were obliged to re-purpose existing drugs to fight this pandemic.
This is a multicenter, randomized, double blind, parallel placebo controlled, phase 3 clinical trial to evaluate the protective efficacy, safety and immunogenicity of inactivated SARS-CoV-2 vaccines in healthy population 18 years old and above.
The purpose of this trial is to understand whether: 1. Metformin vs fluvoxamine vs ivermectin vs metformin+fluvoxamine vs metformin+ivermectin is superior to placebo in non-hospitalized adults with SARS-CoV-2 disease for preventing Covid-19 disease progression. 2. To understand if the active treatment arms are superior to placebo in improving viral load, serologic markers associated with Covid-19, and gut microbiome in non-hospitalized adults with SARS-CoV-2 infection. 3. To understand if any of the active treatment arms prevent long-covid syndrome, PASC (post-acute sequelae of SARS-CoV-2 infection).
