Filter by:This study will evaluate intracutaneous delivery of 0.1, 0.25 and 0.5 milliliter volumes of saline from the FLUGEN 101.2 investigational microneedle-based device.
The primary research aim of this project is to test the effectiveness of a comprehensive, evidence-based vaccine promotion package implemented in the obstetric setting on increasing the likelihood that a pregnant woman in Georgia will receive an influenza and/or pertussis vaccine.
Influenza is an important and potentially preventable cause of morbidity and mortality, yet only 46% of U.S. adults were vaccinated by the end of the 2011-12 influenza season despite influenza vaccination being widely recommended, effective, and safe. Influenza vaccination rates are even lower in racial/ethnic minority groups. In order to address the problem of low influenza vaccination rates in minority adults, we plan to build on the well-accepted practice of immunization recall-reminders and the emerging practice of using text message to pilot the feasibility of using text messaging to improve influenza vaccination coverage rates in a low health literacy, largely minority, publicly insured adult population.
This is an open study of the use of AdimFlu-V (2012-2013 season) vaccine in non-elderly and elderly subjects. All participates will receive one dose of vaccine (0.5 ml) by intramuscular injection into the upper arm. Safety outcomes included immediate reactions at the time of vaccination, solicited local and systemic reactions for 7 days, unsolicited adverse events for 28 days, and serious adverse events. Sera prepared from blood samples will be collected from each subject immediately prior to, and 28 days after vaccination. Anti-hemagglutinin (HA) antibody titers will be determined using the WHO hemagglutination inhibition reference technique. The central laboratory who is responsible for antibody titrations will not be aware of the background of blood samples (e.g., pre- or post-serum), it is also called observer-blinded. All participates will be followed, either by clinical visit or by telephone contact, for 8 weeks after the vaccination for safety reasons.
The purpose of this study is to assess in healthy subjects the safety, tolerability, pharmacokinetics and immunogenicity of single escalating doses of CR8020, a monoclonal antibody against influenza A viruses.
This is an open study of the use of AdimFlu-V (2012-2013 season) vaccine in young healthy subjects. Subjects aged equal to or over 9 years old and less than 18 years old will receive one dose of vaccine (0.5 mL) by intramuscular injection into the upper arm. Subjects aged equal to or over 3 years old and less than 9 years old will received two doses of vaccine (0.5 mL) by intramuscular injection into the upper arm separated by 4 weeks (28 days). Safety outcomes included immediate reactions at the time of vaccination, solicited local and systemic reactions within 7 days after each vaccination, unsolicited adverse events observed since first vaccination to 28 days after the last dose of vaccination, and serious adverse events during the observation. Sera prepared from blood samples will be collected from each subject immediately prior to, and 4 weeks after each vaccination. Anti-hemagglutinin (HA) antibody titers will be determined using the WHO hemagglutination inhibition reference technique. The central laboratory who is responsible for antibody titrations will not be aware of the background of blood samples (e.g., pre- or post-serum), it is also called observer-blinded. All subjects will be followed, either by clinical visit or by telephone contact, for 8 weeks after the last vaccination for safety reasons.
The purpose of this study is to evaluate the antibody response to each of the three influenza vaccine strains included in the licensed seasonal flu vaccine, as measured by hemagglutination inhibition (HAI) at three weeks post immunization in non-elderly and elderly subjects in compliance with the requirements of the current European Union (EU) recommendations for the evaluation of the immunogenicity for a new formulation of a licensed flu vaccine (CPMP/BWP/214/96).
Background: - Influenza (flu) is a virus that causes people to get sick. Most of the time, the flu causes only a mild illness, but some people can become seriously ill or even die from it. Currently, some pills and inhaled powders can be used to treat the flu, but they only make flu symptoms end about a day sooner. More treatment choices for the flu are needed, especially for those who become seriously ill. Researchers want to test a new drug, AVI-7100, that might keep a person who takes it from having a more serious case of the flu. Objectives: - To see how healthy adult volunteers tolerate the AVI-7100 anti-influenza drug. Eligibility: - Healthy volunteers of normal weight between 18 and 60 years of age. Design: - Participants will be screened with a physical exam and medical history. Blood and urine samples will be collected. A heart function test will also be performed. - Participants will have either AVI-7100 or a placebo infusion. They will not know which infusion they have. . Participants will stay at the clinical center for a total of 8 hours after the infusion. Blood samples will be collected 1, 2, 4, and 8 hours after the end of the infusion - Participants will return on Days 1, 2, 4, 10, and 28 after receiving the drug. Blood and urine samples will be collected. A heart function test will also be performed. - There will be a second part of the study that is separate from the first one. Additional people will receive either AVI-7100 or placebo to test their reactions to a specific dose.
This is a Phase II open-label study in approximately 200, and up to 240, healthy males and non-pregnant females, aged 18 years and older. This study is designed to assess the safety, reactogenicity, and immunogenicity of an unadjuvanted subvirion monovalent inactivated influenza H3N2v vaccine manufactured by Sanofi Pasteur. Subjects will be stratified by age (approximately 100 (up to 120) subjects 18-64 years old and approximately 100 (up to 120) subjects >/= 65 years old) to receive two doses of vaccine, delivered intramuscularly as 15mcg HA/0.5mL dose, 21 days apart. The duration of the study for each subject will be approximately 7 months.
This protocol will seek to enroll 372 adult otherwise healthy subjects presenting with influenza-like illness (ILI). Subjects will enter the study based on listed inclusion/exclusion criteria, including a positive Rapid Antigen Test (RAT) for influenza virus (IFV). Subjects will be randomized into one of three treatment groups: a DAS181 30 mg total dose group (DAS181-F02 formulation), a DAS181 60 mg total dose group (DAS181-F04 formulation) or a placebo group. The modified intent to treat (mITT) analysis set will include subjects with confirmed influenza as documented by qPCR or TCID50. The full analysis set will be used for activity analysis and will include all randomized subjects with baseline and treatment data. Per protocol, the safety analysis sets are described below in statistical methods. A subpopulation of 60 participants will also have additional PK and Immunogenicity blood samples collected. For this subgroup, PK and Immunogenicity samples will be collected at all study visits.
