Filter by:This is a randomized, double-blinded, placebo-controlled, multi center, dose ranging study of safety and efficacy in both volunteers with chronic hepatitis B virus infection and in volunteers with hepatitis D virus coinfection. Volunteers will be administered multiple oral doses of ATI-2173 and assessed for safety and efficacy including blood tests to show how the body metabolizes and eliminates the investigational drug as well as how the drug effects the virus infection.
This is an open label controlled household-randomised trial designed to evaluate the efficacy of RESP301 alongside standard of care ("SOC") versus SOC alone.
Approximately 40 million people in the US are served by private, and frequently untreated, wells. Our best estimate is that 1.3 million cases of gastrointestinal illnesses (GI) per year are attributed to consuming water from untreated private wells in the US, but in reality, there are no robust epidemiological data that can be used to estimate cases of GI attributable to these sources. We propose the first randomized controlled trial (RCT) to estimate the burden of GI associated with private well water. We will test if household treatment of private well water by ultraviolet light (UV) vs. sham (inactive UV device) decreases the incidence of GI in children under 5. We will also examine the presence of viral, bacterial, and protozoan pathogens in stool and well water from participants. These data will fill a knowledge gap on sporadic GI associated with federally-unregulated private water supplies in the US.
This study will test the filtration, air leak, and breathability of a newly designed fully washable mask developed by Dr. Nordell with the Mayo Clinic. This mask is theorized to be a superior alternative to other respirators currently used when one-time-use N95 masks are unavailable.
This study seeks to identify and test host RNA expression profiles as markers for infections in young infants. Preliminary studies have shown high sensitivity and specificity for the discrimination of bacterial from non-bacterial infections in children, but the method has only been investigated in a limited number of young infants. The study aims to include 65 young infants with serious bacterial infections. The samples will be analysed by RNA sequencing. New diagnostic tools may help reduce unnecessary antibiotic treatment, antibiotic resistance, side-effects, hospitalisation and invasive procedures.
Acute lung injury (ALI) and acute respiratory distress syndrome (ARDS) are the most frequent complications of the COVID-19 pandemic. In these conditions, hypoxemia may result from : i) a pulmonary vascular dilatation resulting from an impaired hypoxic pulmonary vasoconstriction and leading to ventilation-perfusion mismatching within the lungs and ii) thrombosis-mediated perfusion defects. Pulmonary vascular dilation might be due to a relative failure of the physiological acute hypoxic pulmonary vasoconstriction, in the context of an over-activation of a regional vasodilatation cascade, as part of a dysfunctional inflammatory process. Perfusion abnormalities associated with pulmonary vascular dilation are suggestive of intrapulmonary shunting toward areas where gas exchange is impaired, ultimately leading to a worsening ventilation-perfusion mismatch, a regional hypoxia and a profound hypoxemia. Increased plasma levels of VEGF have been reported in moderate to severe COVID-19 pneumonia, highlighting the role of VEGF in the pathophysiology of the disease. A better prognosis has been reported in critically ill patients with lower levels of growth factors, HGF and VEGF-A at the time of ICU admission. Recent data of the study NCT 04275414 by Pang J et al have suggested that patients receiving a single-dose of bevacizumab have improved their oxygen support status in 92% of cases during a 28-day follow-up period, as compared with 62% of cases in an external cohort receiving standard care. Correcting endothelial permeability and vasodilatation with VEGF-targeted therapy could allow repair damaged vascular endothelium, have an indirect anti-inflammatory effect (limiting alveolar exudation of circulating inflammatory and procoagulant mediators) and improve oxygenation and therefore reduce the proportion of patients with severe forms requiring ICU referral and finally patient death. This clinical trial will therefore focus on the specific efficacy of bevacizumab in COVID-19 patients with severe hypoxemia.
- Three measures are currently being implemented to control Ebola outbreaks: - Monitoring of contacts - Isolation and treatment of sick people - Vaccination of the population in high-risk areas. - In contacts with high viral exposure and therefore a high risk of incubation and rapid expression of infection, the r-VSV-ZEBOV vaccine does not provide adequate protection because vaccine antibody production is effective 6 to 10 days after administration. - Specific monoclonal antibodies (Mab) from the Regeneron and mAb114 research specialties have been shown to be effective in reducing mortality in patients with Ebola virus disease (EVD). - Their use in a single parenteral administration and good tolerability make them candidates for use in post-exposure prophylaxis (PEP) in individuals at high risk of viral exposure. - A comprehensive strategy for the protection of high-risk contacts must therefore be implemented, including the vaccine and the Mabs, to ensure both immediate and prolonged protection. Indeed, the efficacy of the vaccine is likely to be diminished when co-administered with Mabs, as both strategies share the same viral target (the GP envelope glycoprotein) and the vaccine is replicative (and therefore may be inhibited by Mabs). PROVAE aim to evaluate the effectiveness of a comprehensive strategy to prevent transmission of MVE in contacts at high risk of infection, including (i) post-exposure prophylaxis with Mabs and (ii) vaccination with r-VSV-ZEBOV.
This study highlighted the possibility, even in epidemic settings, of providing advanced supportive care for patients with VMEs. Indeed, while the prospect of offering any invasive medical care was widely discussed in 2014 in West Africa with the aim of limiting the exposure of caregivers, the epidemic of 2018-2019 has on the contrary seen the development of a number of medical care strategies, in parallel with the deployment of specific treatments. This study aims to describe a cohort of patients receiving this upgraded supportive care during the tenth epidemic in the DRC.
A preparation of CimertrA, comprising Artemisinin, Curcumin, and Boswellia, and Vitamin C in a nanoparticular formulation, is proposed as a treatment for the disease associated with the novel coronavirus SARS-CoV-2. This initiative is presented under the urgent circumstances of the fulminant pandemic caused by this lethal disease, which is known as COVID-19 and has spread across the globe causing death and disrupting the normal function of modern society. The grounds for the proposal are rooted in existing knowledge on the components and pharmacological features of this formulation and their relevance to the current understanding of the disease process being addressed. The severe acute respiratory syndrome-associated coronavirus disease 2019 (COVID-19) illness results from the immediate response to the viral infection as well as from a subsequent host inflammatory response. Systemic proinflammatory cytokines and biomarkers are elevated as the disease progresses towards its advanced stages, and correlate with worse chances of survival. Serum cytokine levels that are elevated in patients with Covid-19-associated cytokine storm include interleukin-1β, interleukin-6, IP-10, TNF, interferon-γ, macrophage inflammatory protein (MIP) 1α and 1β, and VEGF. Higher interleukin-6 levels are strongly associated with shorter survival. The relative frequencies of circulating activated CD4+ and CD8+ T cells and plasmablasts are increased in Covid-19. In addition to the elevated systemic cytokine levels and activated immune cells, several clinical and laboratory abnormalities, such as elevated CRP and d-dimer levels, hypoalbuminemia, renal dysfunction, and effusions, are also observed in Covid-19. Laboratory test results reflecting hyper inflammation and tissue damage were found to predict worsening outcomes in Covid-19. CimetrA, comprising Artemisinin, Curcumin, Boswellia, and Vitamin C in a nanoparticular formulation, has been studied on patients with COVID-19 in a randomized double-blind control Phase II study (MGC-006 - under a previous product name - ArtemiC). The study product demonstrated excellent safety and efficacy profiles. Experiments performed in vitro with CimetrA demonstrated the ability to reduce cytokine elevation in response to stimulation of human PBMC preparations. The currently proposed Multi-center multinational-controlled study is designed to include 252 adult patients who suffer from moderate COVID-19 infection. Safety will be assessed through collection and analysis of adverse events, blood and urine laboratory assessments, and vital signs. After the screening visit, the study drug will be administrated twice a day morning and evening (every 12 hours) during (day 1 and day 2) The patients will be randomized in 1:1:1 ratio to study drug (CimetrA) in addition to Standard of Care (Arm 1 (CimetrA-1) or Arm 2 (CimetrA-2)) or Placebo in addition to Standard of Care (Arm 3).
The purpose of the study is to assess the potential therapeutic effect of N-acetylcysteine "NAC" in COVID 19 patients.
