Active clinical trials for "Influenza, Human"

This study will evaluate the safety, tolerability, and systemic exposure of an experimental influenza (flu) treatment medication called DAS181. DAS181 is a dry powder that is administered via oral inhalation using a special device. Study participants will include up to 60 healthy, non-smoking males and females, ages 18-65. They will be given either DAS181 or placebo. Participants will remain in the clinic overnight to be watched for health changes for 24 hours after receiving the medication. Study procedures include: physical exams, chest x-rays, ECGs, lung function tests, collection of blood and urine samples, and throat swabs. Follow-up visits will occur on study days 2, 7, 14 +/- 1 day, and 30 +/- 2 days. Participants will be involved in the study for up to 61 days, which includes the screening period.

This is a Phase 2, randomized, blinded, clinical trial. Up to 500 eligible subjects will be enrolled and randomized in a 1:2:2:1:2:2 ratio into one of six groups, and vaccinated in this study. Subjects will receive an intramuscular injection of the influenza A/H5N1 (low or high dose) on Day 0 with or without a patch (low or high dose).

The trial will examine the efficacy of sambucol in the treatment of influenza. The primary efficacy endpoint will be the length of time to resolution of influenza illness.The double blind trial will be conducted at the Personnel Clinic, and at the Clinical virology Unit, Hadassah University Hospital, and will include 100 patients with laboratory-confirmed influenza infection, 50 in the sambucol and 50 in the placebo study arm.

Influenza, also known as the flu, is a contagious respiratory illness caused by influenza viruses. The illness can range in severity, from mild to severe to even death, and it causes an estimated 500,000 to 1,000,000 deaths worldwide each year. In the last several years, there have been increasing numbers of human cases of avian influenza, or bird flu. This trend may pose a threat of a future pandemic--worldwide outbreak of disease--with an avian influenza virus that can easily spread from person to person. Oseltamivir is an antiviral medication that is used to treat people with uncomplicated human influenza, and it may be effective in treating people with either severe human influenza or avian influenza. The purpose of this international study is to compare standard-dose oseltamivir versus high-dose oseltamivir for treating people who are hospitalized with severe human influenza or avian influenza.

The objective of this study is to demonstrate that influenza vaccination of nursing home workers is an effective intervention for reducing mortality of elderly people.

- Trial to assess asthma exacerbation through to the end of the study; and to demonstrate that the efficacy over one season against culture-confirmed influenza-illness; and finally to assess the safety and tolerability of CAIV-T in children with asthma.

This study seeks to determine the incidence and transmission of avian influenza viruses in humans exposed to poultry. Enrolled subjects will be selected from five different rural areas (villages) in the Nile delta region in Egypt where poultry are commonly raised. From those study sites, 2400 healthy subjects will be monitored for 6 years with annual follow up visits to measure sero-prevalence and exposure variables, and more importantly, biweekly or weekly visits to measure incidence of infection, measure secondary transmission rates, monitor symptoms, and assess immunological response. Primary Objectives: To estimate the incidence of avian influenza (AI) in poultry-exposed human populations. To estimate sero-prevalent of AI in poultry-exposed human populations. To investigate potential risk factors associated with AI human infections in poultry-exposed individuals. To investigate secondary infection risk for household contacts. Secondary Objectives: To characterize the antigenic and genetic makeup of AI viruses infecting humans. To monitor the pathogenicity and disease severity of AI viruses causing human infections and the associated immune response. To investigate the serologic response following confirmed influenza virus infection.

This is a multi-center, randomized, single-blinded, prospective, parallel group intervention study to investigate whether methotrexate (MTX) discontinuation for 1 week is non-inferior to MTX discontinuation for 2 weeks in regard to satisfactory vaccination response to a seasonal influenza.

The investigators will conduct a brief educational intervention to pregnant women who have not yet received the influenza vaccine in this pregnancy to improve the uptake of seasonal influenza vaccine.

The purpose of this trial is to assess the affect of Certolizumab Pegol (CZP) treatment on antibody response to T cell-independent and T cell-dependent immunizations using pneumococcal and influenza vaccines, respectively.
