E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
Immunogenicity Objectives Co-Primary: To demonstrate non-inferiority of the post-vaccination (Day 50) hemagglutination inhibition (HI) geometric mean titer (GMT) of the cell culture-derived influenza vaccine to the corresponding GMT of the egg-derived influenza vaccine for all three strains after two doses administered four weeks apart to a subset of children 3 to 8 years of age (Cohort 3, immunogenicity subset). To demonstrate non-inferiority of the percentages of subjects achieving seroconversion or significant increase in antibody titer at Day 50 following administration of the cell culture-derived influenza vaccine to the corresponding percentages of subjects following administration of the egg-derived influenza vaccine for all three strains after two doses administered four weeks apart to a subset of children 3 to 8 years of age (Cohort 3, immunogenicity subset).Safety Objectives To evaluate safety and tolerability of one dose of either the cell culture-derived or the egg |
|
E.2.2 | Secondary objectives of the trial |
Secondary: To evaluate immunogenicity, measured by seroprotection and by percentage of subjects achieving seroconversion or significant increase, of: - one dose of either the cell culture-derived or the egg-derived influenza vaccine administered to children and adolescents 9 to 17 years of age (Cohort 1) - two doses of either the cell culture-derived or the egg-derived influenza vaccine, administered 4 weeks apart to a subset of children 3 to 8 years of age (Cohort 3, immunogenicity subset) according to both the CPMP/BWP/214/96 guideline and the Center for Biologics Evaluation and Research (CBER) Draft Guidance for Industry issued in March 2006. |
