Active clinical trials for "Severe Acute Respiratory Syndrome"

The purpose of this study is to evaluate the safety and effectiveness of APL-9 in adults with mild to moderate ARDS (acute respiratory distress syndrome) caused by COVID-19 who are hospitalized and require supplemental oxygen therapy with or without mechanical ventilation. It is thought that COVID-19 activates the complement system, part of the immune system that responds to infection or tissue damage, and increases inflammation in the lungs. APL-9 has been designed to inhibit or block activation of part of the complement pathway, and potentially reduce inflammation in the lungs. Part 1 of the study is open-label to evaluate safety; all participants will receive APL-9 plus standard of care. Part 2 of the study is double-blind, randomized; participants will receive either APL-9 or the vehicle-control plus standard of care.

A Phase I, Randomized, Double-Blind, Placebo-Controlled Study to Evaluate the Safety, Tolerability, and Pharmacokinetics of Single and Multiple Ascending Doses of Inhaled MBS-COV in Healthy Participants

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.

The purpose of this Phase III study is to confirm that SNG001 can accelerate the recovery of hospitalised patients receiving oxygen with confirmed Severe Acute Respiratory Syndrome coronavirus 2 (SARS-CoV-2). Safety and other efficacy endpoints will also be assessed.

The ongoing pandemic of SARS CoV-2 virus is calling for effective preventive and theraputic interventions. Vitamin D has been shown to play immunemodulatory functions in human. Low vitamin D levels have been linked to increased susciptability to infections especially the acute respiratory infections. This randomised controlled study aims to explore the effect of vitamin D administration on the outcome of SARS- CoV2 virus

The benefit of the research is to provide information regarding the efficacy and safety of Favipiravir plus the Standard of Care (SoC) for mild-moderate COVID-19 patients to be a reference for policy recommendations regarding the use of Favipiravir as an antiviral drug for the treatment of Covid-19.

The primary objectives of this study are to evaluate the safety and reactogenicity profile after 1 and 2 dose administrations of investigational SARS-CoV-2 mRNA vaccine CVnCoV, and to evaluate the humoral immune responses 14 days after 2 dose administrations of CVnCoV.

In recent months severe acute respiratory syndrome-coronavirus 2 (SARS-CoV-2) has emerged as a novel human pathogen and, susceptibility amongst humans is presumed to be universal. Prevention measures of COVID-19 have included distancing, quarantines, use of facemasks in public places, and hand hygiene measures. Mandatory quarantines have also been applied on index cases and their contacts, as well as an active search for asymptomatic patients. Current strategies to reduce the spread of SARS-CoV-2 do not include measures that could prevent transmission prior to the onset of symptoms. Subjects infected with SARS-CoV-2 have been known to shed virus and be contagious for up to 5 days prior to developing symptoms ('pre-symptomatic transmission'). In fact, nearly 60% of all infected subjects can shed virus pre-symptomatically. Pre- or even asymptomatic shedding occurs across all age groups, contributing to the rapidly expanding pandemic. Post-exposure prophylaxis (PEP) using type 1 interferon (IFN) can potentially eliminate the spread of SARS-CoV-2. IFN could reduce the period of viral shedding by ~1 week. Since pre-symptomatic shedding of virus can start up to 5 days prior to symptom onset, our approach of a PEP intervention to all contacts recently exposed to a case could possibly entirely interrupt the spread of the virus, and with that, the pandemic. The current study focuses on prevention of the disease in addition to its treatment. Thus, the key distinction between these other trials and this study is that this study focuses on containing coronavirus (i.e. cause) in the community, rather than simply its treatment (i.e. consequence) in the individual. Viral spread could be eliminated through interventions effective at abolishing viral transmission. However, such post-exposure prophylaxis interventions, that is initiation of antiviral therapy in pre-infectious contacts to reduce or even eliminate such spread, must be safe since they are given to asymptomatic and possibly uninfected subjects. In none of the previous clinical trials of IFN therapy for SARS-CoV-2 have serious adverse events been recorded. Furthermore, the IFN chosen for this study (pegylated IFN 1b) has been extensively studied in clinical trials, and has been in clinical use for years for multiple sclerosis. Pegylated IFN formulations allow for weekly injections while maintaining serum levels and limiting dose-dependent side effects. Together these data support a sound safety profile for the planned intervention. The aim of this study is to ascertain whether IFN administered to index cases and household contacts of an index case, starting immediately following confirmed exposure (index case confirmed positive for SARS-CoV-2), will reduce duration of SARS-CoV-2 detectable by PCR in the index cases, and incidence of SARS-CoV-2 detectable by PCR in household contacts.
