E.1 Medical condition or disease under investigation |
E.1.1 | Medical condition(s) being investigated |
Influenza poses a significant threat to individual and public health, and influenza vaccination with a trivalent inactivated influenza vaccine is widely recommended to children, adults at risk and elderly. Agrippal is a subunit inactivated influenza vaccine,purifeid,registered in Italy since 1986,recommended in the prevention of influenza in subjects from 6 months of age, in particular in subject at high risk for associated complications |

E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
To evaluate the antibody response to each influenza vaccine antigen, as measured by Single Radial Hemolysis (SRH) 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 hemagglutination inhibition (HI) test for confirmation purposes. (Note for Guidance on Harmonization of Requirements for Influenza Vaccines. CPMP/BWP/214/96: 12 March 1997). |
|
E.2.2 | Secondary objectives of the trial |
To evaluate the safety of a single intramuscular (IM) injection of Agrippal 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). |

E.5 End points |
E.5.1 | Primary end point(s) |
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 60 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 SRH and possibly HI 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. |
