Filter by:The purpose of this study is to determine the antiviral activity and safety of VX-787 given to healthy adult volunteers that have been inoculated with the influenza virus.
The purpose of this study is to determine the immune response of three dose levels of the Novavax Quadrivalent vaccine in healthy young adults (18-64). The study is broken down into 5 treatment groups. Each group will enroll 100 subjects, for a total of 500 subjects. Group 1-3 will receive one of three dose levels of the Novavax Quadrivalent vaccine, Group 4 will receive a dose of the Novavax Trivalent vaccine, and Group 5 will receive a commercially available trivalent influenza vaccine (TIV). The study will also evaluate the safety and tolerability of the Novavax Quadrivalent vaccine.
This study will evaluate the safety and immunogenicity of VAX161B [STF2.HA5 H5N1], a recombinant, inactivated, subunit influenza vaccine given as a two dose regimen at a range of doses.
The clinical trial was designed to evaluate the immunogenicity and safety against pediatric Inactivated influenza vaccine (Split Virion) (0.25ml formulation) of Hualan administered on infants age 6 months to 36 months.
The clinical trial was conducted in Jintan City of Jiangsu Province, China in May, 2006. The purpose of the clinical trial was to evaluate the safety and immunogenicity against Hualan's Influenza Vaccine (Split Virion), Inactivated (0.5ml) administered on age 6 months and old population.

Rationale: Classical antiviral therapies target viral proteins and are consequently subject to resistance. To counteract this limitation, alternative strategies have been developed that target cellular factors. We hypothesized that such an approach could also be useful to identify broad-spectrum antivirals. The influenza A virus was used as a model for its viral diversity and because of the need to develop therapies against unpredictable viruses as recently underlined by the H1N1 pandemic. Gene-expression signature-based screening identified broadly effective influenza A antivirals. Midodrine showed great results in inhibiting viral growth and was the most suited to confirm its efficacy in vivo. The main objective of the study is to assess the efficacy of midodrine taken at usual recommended dose (7.5mg/day) versus no treatment on viral replication kinetics of virus Influenza A. Secondary objectives: evaluation of the number of patients with a normalized viral load 2, 3 5 and 7 days post-treatment; description of the anti-viral efficacy of midodrine defined as the delay to obtain a prolonged negativity of viral RNA; description of the tolerance of midodrine, evaluation of the clinical response to study treatment; evaluation of the dynamic of viral replication; analysis of the frequency of emergence of mutants and associated resistance. Methods: This is a multicenter, randomized, open-label study comparing patients aged 18 to 65 years infected by influenza A virus. Nasopharyngeal washing will be performed at day 0 (randomization), 2, 3, 5 to show the viral replication evolution. 161 patients will be randomized as follows : - Arm 1 : Midodrine, 2.5 mg, 3 times a day - Arm 2 : No treatment The recruitment is performed by general practitioners in the Lyon area.
This is a Phase I, randomized controlled trial to evaluate the safety of Lactobacillus rhamnosus GG (LGG) versus placebo in elderly subjects receiving the live attenuated influenza vaccine. Lactobacilli are part of the normal flora of the intestine. LGG is one of several strains of Lactobacilli that is used as a probiotic or microorganism administered to confer "health benefits". Our research is focused on studying the possible therapeutic effects of LGG. The study hypotheses are: 1. LGG or placebo administered twice daily will be safe and well tolerated in elderly subjects who have just received the live attenuated influenza vaccine, 2. The immune response to the influenza vaccine at day 21, 28, and 56 will be higher in the LGG group than the placebo group, 3. The diversity of the microbiota in nasopharyngeal and stool specimens at day 21, 28, and 56 will be greater in the LGG group than the placebo group.
This study will assess the efficacy of a new intradermal formulation of the trivalent inactivated influenza vaccine compared to the standard intramuscular vaccine in HIV-infected men who have sex with men in Bangkok, Thailand. Relative efficacy of the two different formulations of influenza vaccine will be assessed by comparing immunologic responses to vaccine between the two study arms.
