Safety Objectives: To evaluate the safety of a single intramuscular (IM) injection of
Optaflu in adult and elderly subjects in compliance with the requirements of the current
EU recommendations for clinical trials related to yearly licensing of influenza vaccines
(CPMP/BWP/214/96).
Immunogenicity Objectives:
Primary
To evaluate the antibody response to each influenza vaccine antigen, as measured by hemagglutination inhibition (HI) at 21 days post-immunization in adult and elderly
subjects in compliance with the requirements of the current EU recommendations for
clinical trials related to yearly licensing of influenza vaccines.
Antibodies maybe additionally quantified using the Single Radial Hemolysis (SRH) test
for confirmation purposes. (Note for Guidance on Harmonization of Requirements for
Influenza Vaccines. CPMP/BWP/214/96: 12 March 1997). |

E.5 End points |
E.5.1 | Primary end point(s) |
Immunogenicity Endpoints
The following serological assessments will be considered for each strain in non-elderly
adult subjects, aged between 18 and 60, and at least one of the assessments should meet
the indicated requirements:
- The proportion of subjects achieving seroconversion or significant increase in HI
titer or SRH area > 40%
- Mean geometric increase > 2.5
- The proportion of subjects achieving an HI titer ≥ 40 or SRH area ≥ 25 mm2
should be > 70%
The following serological assessments will be considered for each strain in elderly
subjects, aged 61 years and over, and at least one of the assessments should meet the
indicated requirements:
- Proportion of seroconversion or significant increase in HI titer or SRH area >
30%
- Mean geometric increase > 2.0
- The proportion of subjects achieving an HI titer ≥ 40 or SRH area ≥ 25 mm2
should be > 60%
Circulating anti-HA antibodies will be measured by HI and possibly SRH assay just
prior to vaccination (Day 1) and approximately 3 weeks after the vaccination (Day 22).
For the purposes of calculation, any HI result < 10 (i.e. undetectable) will be expressed
as 5, and any negative SRH result will be expressed as 4 mm2.
In HI tests, seroconversion or significant increase in antibody titer corresponds to:
negative pre-vaccination serum / post-vaccination serum titer ≥ 40 or
at least a four-fold increase in titer from positive pre-vaccination serum
In SRH tests, seroconversion or significant increase in antibody titer corresponds to:
negative pre-vaccination serum / post-vaccination serum area ≥ 25 mm2
at least a 50% increase in area from positive pre-vaccination serum
Safety Endpoints
Safety will be assessed in accordance with available safety data on influenza vaccines:
Local and systemic reactions will be assessed for 3 days post the day of
vaccination
AEs Days 1 to 4. All AEs necessitating a physician’s visit or consultation and/or leading
to premature study discontinuation and all SAEs until Day 22 of until resolution. |
