Active clinical trials for "Influenza, Human"

This is a Phase 2, randomized, double-blind, placebo-controlled single dose study in otherwise healthy adults with acute uncomplicated seasonal influenza A to assess the safety and tolerability, efficacy, and pharmacokinetics of MHAA4549A.

A phase 2 a study to assess the safety profile and the effect of VIS410 in healthy subjects after inoculation with influenza A virus (H1N1).

Title: An adaptive study of the pharmacokinetics of favipiravir in patients with severe influenza Study Design: An open label, single group assignment, adaptive study to evaluate the pharmacokinetics of favipiravir in adult patients with severe influenza. In the first stage, participants will receive favipiravir 1600mg BID on day 1, followed by favipiravir 600mg BID for 9 days. If the proportion of patients with a minimum observed plasma trough concentration above the MEC (20μg/ml) at all measured time points after the second dose is less than 80% then a second patient cohort will be recruited and will receive favipiravir 1800mg BID on day 1, followed by favipiravir 800mg BID for 9 days. Intervention: The 1st stage: 1600mg BID on day 1, followed with 600mg BID for 9 days. Sample size: 15 The 2nd stage: 1800mg BID on day 1, followed with 800mg BID for 9 days. Sample size: 15 Population: Males and females aged 18 years or older admitted to hospital with a positive PCR test for influenza and a PaO2/FiO2≤300mmHg or/and on mechanical ventilation for severe lung infection on admission. Sample size 15 or 30 severe influenza patients Research hypothesis The administration of oral favipiravir at either 1600mg/600mg BID or 1800/800mg BID will result in ≥ 80% patients achieving a minimum observed plasma trough concentration above the MEC (20μg/ml) at all measured time points after the second dose. Phase: Phase 2a, PK, safety and feasibility study. Description of Study Agent: Favipiravir (T-705) a viral RNA-dependent RNA polymerase inhibitor. Study Duration: 1 year Participant Duration: 38 days

Peramivir is the first intravenous neuraminidase inhibitor (NAI) available for treatment of uncomplicated influenza in adults. Data from placebo-controlled trials in outpatients have shown antiviral efficacy, safety, and tolerability. Although the unmet need for intravenous therapy lies mainly with patients hospitalized with complicated diseases, such data are limited because of feasibility and ethical considerations for placebo-controlled studies. In this study, the investigators aimed to examine more specifically treatment effects of peramivir in adults hospitalized with influenza-associated lower respiratory tract complications (LRTC). Such findings may have important implications on clinical management.

The purpose of this study is to determine whether Ingavirin® 90 mg once daily is effective and safe for the treatment of influenza and other laboratory confirmed acute respiratory viral infections in the course of standard therapy in patients 18-60 years old.

The purpose of this study is to assess the safety and immunogenicity of two doses of the H1N1 candidate vaccine administered in children aged between 8 and 12 weeks at the time of first vaccination.

The purpose of this study is to determine whether zanamivir aqueous solution given by intravenous injection is safe in treating hospitalized patients with confirmed influenza infection. A single arm open-label design has been selected to achieve the primary objective of providing regulatory authorities with safety data on IV zanamivir.

The purpose of this study is to evaluate the safety, reactogenicity and immunogenicity of GSK2231395A candidate vaccine in adults and elderly adults with chronic obstructive pulmonary disease. Subjects will be vaccinated 3 times with an interval of respectively 2 and 10 months.

Rituximab is a genetically engineered chimeric anti-CD20 monoclonal antibody that selectively targets CD20+ B cells and induces a transient depletion of the CD20+ mature B cell subpopulation.The objective of our study was to assess the effect of rituximab on the efficacy and safety of influenza virus vaccine in patients with rheumatoid arthritis (RA).

This 2-arm study will investigate the safety and tolerability of oseltamivir for the treatment of influenza in immunocompromised participants and characterize the effects of oseltamivir in immunocompromised participants on the development of resistant influenza virus. Eligible immunocompromised participants with laboratory-confirmed influenza will be randomized to receive either conventional dose (30 milligrams [mg] to 75 mg twice daily orally [po], depending on age and weight) or double dose (60 mg-150 mg twice daily po depending on age and weight) olseltamivir for 10 days. Nasal and throat swabs will be taken, and safety evaluations made, at intervals during the study. The anticipated time on study medication is 10 days and the anticipated time on study is 40 days.
