E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
Primary To demonstrate the non-inferiority of antibody responses of two 0.5 mL intramuscular (IM) injections administered 3 weeks apart of a monovalent MF59-adjuvanted H5N1 pandemic vaccine containing 3.75µg H5N1 antigen dose to a pandemic vaccine containing a 7.5µg H5N1antigen dose in terms of post-immunization geometric mean titers (GMT) Co-Primary Once non-inferiority has been shown as determined by SRH, subsequently non-inferiority will be assessed as determined by HI test in a stepwise procedure, thus non-inferiority can be concluded if either non-inferiority can be shown for SRH only or if it can be shown for both SRH and HI |
|
E.2.2 | Secondary objectives of the trial |
A. To evaluate the immunogenicity of two 0.5 mL intramuscular (IM) injections of a monovalent MF59-adjuvanted H5N1 pandemic vaccine containing 3.75µg H5N1 antigen dose and a pandemic vaccine containing a 7.5µg H5N1antigen dose according to CHMP criteria in terms of seroprotection, seroconversion and geometric mean ratio (CPMP/BWP/214/96) as determined by single radial hemolysis (SRH) in non-elderly adult and elderly subjects separately, for all post-vaccination blood sampling days B. To evaluate the immunogenicity according to CHMP criteria in terms of seroprotection, seroconversion and geometric mean ratio (CPMP/BWP/214/96) as determined by hemagglutination inhibition (HI) C. To evaluate the immunogenicity according to CBER criteria in terms of hemagglutination inhibition (HI) and microneutralization (MN) test D. To evaluate the immunogenicity as measured by microneutralization (MN) test |
