Active clinical trials for "Influenza, Human"

Seasonal influenza epidemics are important causes of morbidity and mortality. Cytokine dysregulation, with high levels of pro-inflammatory cytokines, occurs in patients with severe influenza. Early therapy with a neuraminidase inhibitor (NAI) is associated with better outcome in patients hospitalized with influenza, but significant mortality occurs despite use of antivirals. N-acetylcysteine (NAC) is a modified form of the amino acid cysteine, with anti-oxidant properties. NAC was shown to inhibit the production of pro-inflammatory molecules in lung epithelial cells infected with influenza viruses. Previous case report showed that high dose NAC, administered as continuous intravenous infusion, was effective and safe in improving the clinical outcomes. We aim to perform a randomized controlled trial to evaluate the therapeutic role of adjunctive NAC in the clinical management of patients with influenza complicated by lower respiratory tract involvement and abnormal respiratory status. Such information when available may reveal the potential of NAC for optimization of management of severe influenza, and provide important insights into future adjunctive therapy research.

This is a randomized, double-blind, placebo-controlled Phase 2-like, investigator-directed trial of hospitalized patients with laboratory confirmed influenza. Eligible and consented patients will be randomly assigned, in a 1:1 ratio, to one of two groups: Group 1, the combination treatment group (oseltamivir and baloxavir); Group 2, the standard treatment group (oseltamivir and placebo).

This study will evaluate the efficacy, safety, and population pharmacokinetics of a single, oral dose of GP681 compared with placebo in patients aged 12 to 65 years with acute uncomplicated influenza virus infection

This study was a randomized controlled trial to investigate the immune response of influenza vaccines when doses were increased. and a second vaccination together with an increase in the amount of vaccine in patients with chronic kidney disease receiving hemodialysis

This trial will use a previously validated platform, to quantitatively assess antiviral effects in low-risk patients with high viral burdens and uncomplicated influenza, to determine in-vivo antiviral activity. In this randomised, open-label, controlled, group sequential, adaptive, platform trial, we will compare the performance of available influenza antivirals, and those with potential activity, relative to the control (no treatment) and each other. AD ASTRA study is supported by the Wellcome Trust Grant ref: 223195/Z/21/Z through the COVID-19 Therapeutics Accelerator

The goal of this clinical trial is to compare ZX-7101A in Chinese Adults patients with uncomplicated influenza. The main questions it aims to answer are: The efficacy of ZX-7101A in Chinese Adults patients with uncomplicated influenza. The safety of ZX-7101A in Chinese Adults patients with uncomplicated influenza.

The objective of this multicenter, open, single-dose, parallel controlled, Phase I clinical study is to Evaluate a single oral ZX-7101A PK in subjects with varying degrees of (mild or moderate) liver insufficiency compared with healthy subjects matched by age, weight, and sex. And to evaluate the the safety and tolerability of ZX-7101A by a single oral dose in subjects. The main questions it aims to answer are: Evaluate a single oral ZX-7101A PK in subjects with varying degrees of (mild or moderate) liver dysfunction and healthy subjects with normal liver function matched for age, weight, and sex. To evaluate the safety and tolerability of ZX-7101A by a single oral dose in subjects.

This is a phase 2a double-blind, randomized, placebo-controlled study to evaluate the efficacy and safety of molnupiravir (MK-4482) in healthy participants inoculated with experimental influenza virus. The primary hypotheses are that MK-4482 initiated 12 hours following intranasal inoculation of the influenza challenge virus reduces the peak viral load compared to placebo and that MK-4482 initiated 2 days following intranasal inoculation of the influenza challenge virus reduces the viral load area under the curve (AUC) compared to placebo.

This is a randomized, double-blind, placebo-controlled pilot study of the efficacy and safety of baloxavir in combination with oseltamivir (standard of care) for the treatment of influenza in allogeneic stem cell transplant patients. Although there are no data about this treatment option currently available, the investigator hypothesizes that combination therapy may be more effective in clearing influenza virus infection and decreasing the rate of emergence of resistant influenza in immunocompromised human hosts.

To investigate the safety and tolerance of a single infusion of ProTrans® in subjects with "severe" respiratory complications associated with pneumonia caused by COVID-19, Influenza A, Metapneumovirus or RSV infection.
