Active clinical trials for "Influenza, Human"

Seasonal influenza is responsible for many hospitalizations and deaths each year, despite effective antiviral treatments. Some individuals have medical conditions such as heart or lung diseases that make them particularly at risk of severe influenza infections that may result in hospitalization or death. Oseltamivir (Tamiflu) is used most often to treat flu, but there are still many hospitalizations, complications, and deaths even with treatment. This study evaluated the use of combination antivirals (amantadine, oseltamivir, and ribavirin) compared to oseltamivir alone in the treatment of influenza in an at-risk population.

Current guidelines recommend early initiation of empiric antibiotic therapy to cover typical and atypical bacteria that may cause community-acquired pneumonia (CAP). Influenza antiviral therapy in patients with suspected or confirmed influenza. However, many clinicians do not suspect influenza among patients with CAP or other acute lower respiratory tract illness (LRTI) and often do not test for influenza. Additionally, results from currently available diagnostic tests for influenza may be delayed and several tests have low sensitivity and will give false negative results. Thus, anti-influenza treatment for patients with hospitalized influenza CAP and LRTI is frequently initiated late if at all. There is an association between delayed time to administration of empiric antibiotic therapy with increased clinical failure and mortality. As a result, empiric antibiotic therapy for patients with suspect CAP is begun within 4 - 6 hours of hospitalization. This has recently been demonstrated for delayed antiviral treatment as well. We hypothesize that, as happens with early empiric antibiotics for bacterial CAP, a standardized approach of adding early empiric anti-influenza therapy during the influenza season to hospitalized patients with suspect CAP and LRTI will improve clinical outcomes of patients with influenza associated CAP and LRTI. To test our hypothesis we plan a prospective, randomized, multicenter clinical trial of hospitalized patients with acute LRTI, including suspect CAP, during . If early anti-influenza medications were not included on the patients admission orders, patients will be randomized to standard care, including empiric antibacterial therapy as recommended by ATS/IDSA guidelines plus standard influenza diagnostics and treatment (Standard of care) versus early initiation of empiric antiinfluenza therapy plus standard care, e.g. empiric antibacterial (oseltamivir group). The primary study outcome will be development of clinical failure and selected clinical outcomes during the 30 days after enrollment. Other clinical outcomes that will be compared between study groups include time to clinical stability, duration of hospitalization, development of cardiovascular events, re-hospitalization, short-term mortality (30 days), and long-term mortality (1 year). The secondary study outcome will be the cost-effectiveness of the intervention.

The purpose of this study is to compare the safety profile in healthy volunteers of a single intravenous administration of TCN-032 as compared with placebo.

Influenza poses a significant threat to individual and public health, and influenza vaccination with a trivalent inactivated influenza vaccine is widely recommended to children, adults at risks and elderly. Due to antigenic changes of influenza viruses, the virus strains used in interpandemic influenza vaccines are adjusted every year according to WHO (World Health Organization) and CHMP (Committee for Medicinal Products for Human Use) recommendations. Following a change in the vaccine antigen composition recommendation from the previous season, immunogenicity and tolerability of the newly composed vaccines are subject of evaluation in an annual clinical trial in non-elderly adult and elderly subjects according to the guidelines set by EMEA (CPMP/BWP/214/96).

The purpose of this study is to assess in healthy subjects the safety, tolerability, pharmacokinetics and immunogenicity of single escalating doses of CR6261, a monoclonal antibody against influenza A viruses.

Influenza vaccination reduces the morbidity and mortality associated with influenza infection in at risk groups including the elderly and individuals with an impaired immune response, but is not totally protective in all recipient. Cytokines including type I interferons are known to play a key role in the innate immune response to virus infection and in the induction of the primary adaptive-immune response. Thus, we evaluated the safety of sublingual administration of IFNa and its effect on immune response to influenza vaccination in a randomized double-blind placebo controlled study in elderly institutionalized individuals.

This protocol will seek to enroll adult otherwise healthy subjects presenting with influenza-like illness (ILI). Subjects will enter the study based on listed inclusion/exclusion criteria, including a positive diagnostic test for influenza virus (IFV).

The objectives of the study are to demonstrate the effectiveness, safety and tolerability of multiple daily doses of inhaled PUR003, in comparison with placebo, in healthy adults experimentally inoculated with Influenza A/Wisconsin/67/2005 (H3N2) virus.

This open-label study will assess the pharmacokinetics/pharmacodynamics and safety of intravenous (iv) Tamiflu (oseltamivir) in 3 cohorts of children, aged 6-12, 3-5 and 1-2 years, with influenza infection. Patients will receive iv Tamiflu therapy for 5 days (10 doses). For patients whose conditions no longer merit continued iv dosing, therapy may be switched to oral Tamiflu to complete their prescribed course of treatment. If medically necessary, iv or oral therapy with Tamiflu may be continued for up to 5 additional days. Anticipated time on study treatment is 5 to 10 days.

The project is to evaluate immunogenicity, efficacy and tolerance of vaccination against influenza (seasonal and H1N1) in patients affected with systemic and autoimmune diseases.
