ClinicalTrials.gov Identifier:
NCT01651104
First received: July 24, 2012

Last verified: April 2014
  Purpose

To evaluate the safety of a single intramuscular (IM) injection of trivalent adjuvanted influenza study vaccine, formulation 2012/2013, in elderly subjects and the antibody response to each influenza vaccine antigen, as measured by single radial hemolysis (SRH) and hemagglutination inhibition (HI) at approximately 21 days postimmunization in elderly subjects in compliance with the requirements of the current EU recommendations for clinical trials related to yearly licensing of influenza vaccines.

Primary Outcome Measures:
  • Percentages of Subjects Who Achieved Seroconversion or Significant Increase in SRH Area Against Each of Three Vaccine Strains After One Vaccination of aTIV [ Time Frame: Day 22 ] [ Designated as safety issue: No ]

    Immunogenicity was measured as the percentage of subjects who achieved seroconversion or significant increase in single radial hemolysis (SRH) area, against each of three vaccine strains, three weeks after vaccination (day 22), evaluated using SRH assay.

    Seroconversion or significant increase in SRH area was defined as the percentage of subjects with a negative prevaccination serum (SRH area ≤4 mm2) to a postvaccination SRH area ≥25 mm2; or a significant increase in antibody titer from a non-negative prevaccination serum, i.e., at least a 50% increase in area.

    The European (CHMP) criterion is met if percentage of subjects achieving seroconversion or significant increase in SRH area is 30% (≥65 years).


  • Geometric Mean Ratio of Subjects Against Each of Three Vaccine Strains After One Vaccination of aTIV [ Time Frame: Day 22 ] [ Designated as safety issue: No ]

    Geometric mean ratio (GMR) of subjects was calculated as the ratio of postvaccination to prevaccination SRH geometric mean areas (GMAs), directed against each of three vaccine strains, three weeks after vaccination (day 22).

    The CHMP criterion was met if the geometric mean increase (GMR, day 22/day 1) in SRH antibody area is >2.0 (≥65 years).


  • Percentages of Subjects Who Achieved SRH Area ≥25 mm2 Against Each of Three Vaccine Strains After One Vaccination of aTIV [ Time Frame: Day 1 and 22 ] [ Designated as safety issue: No ]

    Immunogenicity was measured as the percentage of subjects achieving SRH area ≥25 mm2 against each of three vaccine strains at baseline (day 1) and three weeks after aTIV vaccination (day 22).

    This criterion is met according to CHMP guideline if percentage of subjects achieving SRH area ≥25 mm2 is 60% (≥65 years).



Secondary Outcome Measures:
  • Number of Subjects Who Reported Solicited Local and Systemic Reactions (Day 1 - Day 4 Postvaccination) [ Time Frame: From day 1 through day 4 postvaccination ] [ Designated as safety issue: Yes ]
    Safety was assessed as the number of subjects who reported solicited local and systemic reactions from day 1 up to and including day 4 after the aTIV vaccination.
