E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
The H1N1 vaccine (included in the trivalent influenza vaccine) when administered twice in transplanted patients, fulfils all serological efficacy criteria at day 21 as required for the elderly population (aged 60 and older) according to the respective European guidance documents. These criteria are 30% for seroconversion rate, 60% for seroprotection rate and 2 for geometric mean ratio (GMR). |
|
E.2.2 | Secondary objectives of the trial |
Main 1.Immune response (IR) of H1N1 vacc is at least as effective in Tx patients as in healthy volunt. Non-inferiority-margin of 0.45 for ratio of geometric mean titers (GMT) of Tx patients&age-matched healthy volunteers (AMHV) (day 21) is used 2.Primary&1st main sec.obj. are evaluated for the other 2 virus strains of trivalent vacc For each virus strain: -Serological efficacy criteria (SEC) for elderly in guidance documents are fulfilled for Tx patients (days 42,280) -Comparison of SEC (seroprotection, seroconversion rates) betw. Tx patients&AMHV -SEC in guidance documents are fulfilled for AMHV (days 21,42,280). Criteria: 40%(seroconv rate), 70%(seroprot rate), 2.5(GMR) -Comparison of IR in relation to immunosuppr. med. in Tx subjects -All serol. assessments&group comparisons measured by microneutralization for Tx patients&AMHV are performed in line with HI analyses (all timepoints). Comparison of safety of triv. vacc overall, and in Tx patients&AMHV

E.5 End points |
E.5.1 | Primary end point(s) |
The observed percentage of seroconversion and seroprotection, as well as the observed GMR (measured by HI) in transplanted patients at day 21 will be compared with the thresholds from the guideline for adults aged over 60. This study is successful, if all three point estimates pass the corresponding efficacy criteria at day 42. For descriptive purpose two-sided 95%-confidence intervals for the rates and the GMR at day 42 will be presented. |
