Filter by:The objectives of this study are to assess the dose-related safety and immunogenicity of six different dose levels of inactivated, Vero cell-derived reverse genetic reassortant A/H5N1/Indonesia/05/2005 influenza vaccine in a healthy young adult population. Subjects will receive 2 vaccinations (21 days apart) at the dose to which they were assigned. Blood will be drawn from all subjects for serum antibody determination on Days 0, 21, 42 and 180. Body temperature will be measured daily for 6 days following vaccination. Injection site reactions and systemic reactions will be monitored throughout the entire 180 days of the study. Safety data obtained at 7 days after the first vaccination for all dose levels in Cohort 1 will be reviewed by a Data Monitoring Committee and a recommendation will be obtained whether to proceed to the second vaccination of Cohort 1 and to the first vaccination of Cohort 2.
A single center, non-randomized clinical trial in two-dose primed healthy adults to evaluate the safety and immunogenicity of a booster dose of an inactivated pandemic influenza (H5N1) vaccine (whole-virion, aluminium-adjuvanted).
A single center, randomized and double-blind phase II clinical trial is to be conducted in adults to evaluate the safety and immunogenicity of an inactivated pandemic influenza vaccine (whole-virion, aluminium-adjuvanted).
This is a Phase 1/2, randomized, observer-blind, placebo-controlled clinical trial. A maximum of 500 eligible subjects in 10 groups will be enrolled, randomized and vaccinated in this study. Subjects will receive an intramuscular injection of either the influenza A/H5N1 (low, medium or high dose) or placebo on Day 0 and Day 21 with or without a patch. This study will be performed in two parts. In Part 1, an initial safety evaluation will be performed in 100 randomized subjects. A Safety Review Committee (SRC)will review all safety data, including laboratory values, through the Day 7 visit, and compare those data against Stopping Criteria. If the treatments are considered safe, Part 2 of the study will be initiated and a second vaccination will be administered to subjects in Part 1 on Day 21. In Part 2, the remaining 400 subjects will be randomized, treated, and will follow the same visit structure and protocol-defined requirements as subjects in Part 1, without the additional laboratory safety measurements. An SRC review will also be performed of all safety data through the Day 28 visit for subjects participating in Part 1.
This is a Phase I/IIa randomized, double-blind, placebo-controlled study to evaluate the safety, reactogenicity, and immunogenicity of 3 potencies (dosages) of H5N1 VLP vaccine or placebo in healthy adults 18 to 40 years of age.
The purpose of this study is to test different adjuvanted vaccine formulations as a two-dose schedule in immunologically naïve adults against one vaccine formulation without adjuvant in terms of tolerance and immunogenicity Primary Objective: To describe the safety profile and immunogenicity following each injection.
