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 risks and elderly. Due to antigenic changes of influenza viruses, the virus strains used in interpandemic influenza vaccines are adjusted every year according to WHO (World Health Organization) and CHMP (Committee for Medicinal Products for Human Use) recommendations. |

E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
Primary To evaluate the antibody response to each influenza vaccine antigen, as measured by Single Radial Hemolysis (SRH) at 21 days post-immunization in 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). Safety Objectives To evaluate the safety of a single intramuscular (IM) injection of FLUAD in 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). |

Individuals participating in any clinical trial with another investigational product 4 weeks prior to first study visit or intent to participate in another clinical study at any time during the conduct of this study. Individuals who received any other vaccines within 4 weeks prior to enrollment in this study or who are planning to receive any vaccine within 4 weeks from the study vaccines. Individuals who have ever received blood, blood products and/or plasma derivatives or any parenteral immunoglobulin preparation in the past 12 weeks and for the full length of the study. Individuals who are part of study personnel or close family members conducting this study. BMI > 35 kg/m2. |

E.5 End points |
E.5.1 | Primary end point(s) |
Immunogenicity Endpoints The following serological assessments should be considered for each strain in elderly subjects, aged 65 and over, and at least one of the assessments should meet the indicated requirements: The proportion of subjects achieving seroconversion or significant increase in anti-HA antibody titer should be > 30% Mean geometric increase should be > 2.0 The proportion of subjects achieving an HI titer ≥ 40 or SRH titer ≥ 25 mm2 should be > 60%. Safety Endpoints Safety will be assessed in accordance with available safety data on influenza vaccines. |
