| E.2 Objective of the trial |
| E.2.1 | Main objective of the trial |
| To demonstrate non-inferiority of antibody responses induced by QIV compared with the licensed 2011-2012 TIV (containing the B/Brisbane strain) and the investigational TIV (containing the B/Florida strain) as assessed in all subjects by geometric mean titer (GMT) for each strain |
|
| E.2.2 | Secondary objectives of the trial |
Safety:
1) To describe the safety profile (injection site reactions, and systemic events) of each vaccine during the 21 days following vaccination, and SAEs, including AESIs, throughout the study in all adult and elderly subjects.
Immunogenicity:
2) To evaluate the compliance, in terms of immunogenicity, of QIV with the requirements of the European Medicines Agency (EMA) Note for Guidance (NfG) CPMP/BWP/214/96 in both age groups
3) To demonstrate, in each age group, superiority of antibody response to the B/Brisbane strain in the QIV group compared to antibody response to the B/Brisbane strain in the TIV2 group
4) To demonstrate, in each age group, superiority of antibody response to the B/Florida strain in the QIV group compared to antibody response to the B/Florida strain in the TIV1 group

| E.5 End points |
| E.5.1 | Primary end point(s) |
| For each group, anti-hemagglutinin (HA) antibody titers for the four strains, as applicable, 21 days (D21) after vaccination. GMTs will be used as the primary parameter |
|
| E.5.1.1 | Timepoint(s) of evaluation of this end point |
|
| E.5.2 | Secondary end point(s) |
Safety / Reactogenicity:
• Occurrence of unsolicited systemic adverse event (AE) reported in the 30 minutes after injection
• Occurrence of solicited (prelisted in the subject diary and electronic Case Report Form [CRF]) injection site reactions and systemic reactions within 7 days following injection
• Occurrence of unsolicited (spontaneously reported) AEs within 21 days following injection
• Occurrence of the following reactions (Medical Dictionary for Regulatory Activities [MedDRA] Preferred Terms given in parentheses) in the 3 days following injection will be more specifically reported (as defined by the EMA NfG [CPMP/BWP/214/96]):
• Injection site induration ≥50 mm for at least 4 consecutive days following injection
• Injection site ecchymosis (injection site hemorrhage) in the 3 days following injection
• Temperature >38°C (pyrexia) for 24 hours or more in the 3 days following injection
• Malaise in the 3 days following injection
• Shivering (chills) in the 3 days following injection
• Occurrence of SAEs including AESIs within the 21 days following vaccination, and up to the end of the trial.
Other endpoints recorded or derived will be described in the statistical analysis plan. Depending on the item, these could include: nature (MedDRA preferred term), time of onset, duration, number of days of occurrence, Grade of severity, relationship to vaccine, action taken, whether the AE led to early termination from the study, seriousness, or outcome.
Note: The following AESIs, considered as important medical events are to be considered as SAEs and reported to the Sponsor: anaphylaxis, Guillain-Barré syndrome (GBS), encephalitis / myelitis, neuritis, convulsions and vasculitis.
Immunogenicity
Immunogenicity will be evaluated using the hemagglutination inhibition (HAI) method in all subjects.
For each vaccine strain, anti-HA antibody titers will be expressed as HAI titers obtained in duplicate, summarized at the subject level by individual geometric mean of duplicates.
The derived endpoints will be:
• Anti-HA individual titer on D0 and D21
• Detectable HAI titer, i.e. with a titer ≥ 10 (1/dil) at D0 and D21
• Individual titer ratios: D21/D0
• Seroprotection status: titer ≥ 40 (1/dil) on D21
• Seroconversion for subjects with a pre-vaccination titer < 10 (1/dil): post-injection titer ≥ 40 (1/dil) on D21 or significant increase for subjects with a pre-vaccination titer ≥ 10 (1/dil): ≥ 4-fold increase from pre- to post-injection titer on D21
For the superiority testing, the GMT will be used as the parameter
