Immunogenicity and Safety Study to Assess Influenza Vaccine Formulated With Haemagglutinin (HA) Antigen From Two Suppliers

29 augusti 2013 uppdaterad av: Crucell Holland BV

Randomized, Parallel-group, Double-blind Multi-center Phase III Study to Assess the Immunogenicity and Safety of the 2010/2011-season Influenza Vaccine Formulated With Haemagglutinin (HA) Antigen From Two Suppliers, in Elderly and Young Adults

The purpose of this study is to assess the humoral immune response and safety of the parenteral formulation of the 2010/2011-season virosomal subunit influenza vaccine Inflexal V using two different HA antigen suppliers (AdImmune and CSL), in groups of young and elderly adults, using the EMA (European Medicines Agency) regulation as a guideline.

Studieöversikt

Detaljerad beskrivning

The objectives of this study are to evaluate the humoral immunogenicity and safety of the parenteral formulation of the 2010/2011-season influenza vaccine, Inflexal V, using HA antigen obtained from 2 different production facilities, and to compare the immunogenicity of both formulations to pre-defined EMA criteria for the annual relicensing of seasonal influenza vaccines. The evaluation will be done in young adults and elderly.

Immunogenicity - Geometric Mean Titer Fold Increase From Baseline
Tidsram: 3 weeks after vaccination (Day 22 ± 2 days)
The primary endpoints were the immunogenicity parameters for HA assessed via hemagglutinin inhibition method (HI). These parameters were analyzed according to the EMA "Note for guidance on harmonisation of requirements for influenza vaccines," 1997 and they were the following: 1. Seroprotection rate, defined as proportion of subjects with HI antibody titer ≥1:40, 2. Seroconversion rate, defined as proportion of subjects with ≥4-fold increase in HI antibody titer and with a titer of ≥1:40, 3. GMT of HI antibodies and fold-increase in GMT
