E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
To evaluate the humoral response [(anti- Haemagglutinin (HA) antibodies tested by Haemagglutination Inhibition (HI)] against each vaccine strain in adults 18-60 years and >60 years of age, 21 days after vaccination with Fluarix/Influsplit Tetra 2013/2014. |
|
E.2.2 | Secondary objectives of the trial |
1) To describe the reactogenicity and safety of Fluarix/Influsplit Tetra 2013/2014 in adults 18-60 years and >60 years of age, in terms of solicited adverse events (AEs), unsolicited AEs, and serious adverse events (SAEs).
2) To evaluate the humoral response (anti-HA antibodies tested by HI) against each vaccine strain, 21 days after vaccination, in adults 18-60 years and >60 years of age who have and who have not received an influenza vaccine during the 2 influenza seasons prior to season 2012/2013. |

• Healthy subjects or subjects with well-controlled chronic diseases as
established by medical history and clinical examination before entering
the study.

study
- Non-childbearing potential is defined as pre-menarche, current tubal
ligation, hysterectomy, ovariectomy or post-menopause

if the subject:
- has practiced adequate contraception for 30 days prior to vaccination,
and

treatment period and for 2 months after completion of vaccination |
|
E.4 | Principal exclusion criteria |
• Participation in previous year's Fluarix registration study (116663)
• Use of any investigational or non-registered product (drug or vaccine)
other than the study vaccine within 30 days preceding the dose of study
vaccine, or planned use during the study period.
• Chronic administration of immunosuppressants or other immunemodifying
drugs within the six months prior to vaccination. Inhaled and
topical steroids are allowed.
• Any administration of a long-acting immune-modifying drug within 6
months before study start, or planned administration during the study
period.
• Administration of immunoglobulins and/or any blood products within
the three months preceding the administration of the study vaccine or
planned administration during the study period.
• Administration of an influenza vaccine within the twelve months
preceding the study vaccination.
• Receipt of a vaccine other than the study vaccine within 30 days before
study vaccination and/or plan to receive any vaccine other than the
study vaccine during the entire study period.
• Clinically or virologically confirmed influenza infection within the six
months preceding the study vaccination.
• Acute disease and/or fever at the time of enrolment.
- Fever is defined as temperature ≥ 37.5°C/99.5°F on oral, axillary or
tympanic setting, or ≥ 38.0°C/100.4°F on rectal setting. The preferred
route for recording temperature in this study will be axillary.
- Subjects with a minor illness (such as mild diarrhoea, mild upper
respiratory infection) without fever may be enrolled at the discretion of
the investigator.
• Acute, clinically significant pulmonary, cardiovascular, hepatic or renal
functional abnormality, as determined by physical examination or
laboratory screening tests.
• Chronic underlying disease (such as cancer, chronic obstructive
pulmonary disease under oxygen therapy, insulin-dependent diabetes
mellitus), not stabilized or clinically serious.
• History of chronic alcohol consumption and/or drug abuse.
• Any confirmed or suspected immunosuppressive or immunodeficient
condition, based on medical history and physical examination (no
laboratory testing required).
• History of Guillain-Barré syndrome.
• History of allergic disease or reactions likely to be exacerbated by any
component of the vaccine including latex.
• Anaphylaxis following the administration of vaccine(s).
• Pregnant or lactating female.
• Female planning to become pregnant or planning to discontinue
contraceptive precautions.
• Any condition which, in the opinion of the investigator, prevents the
subject from participating in the study or would make intramuscular
injection unsafe. |

E.5 End points |
E.5.1 | Primary end point(s) |
Humoral immune response in terms of anti-HA antibodies against each of the four vaccine influenza strains.
The following parameters will be calculated with 95% confidence
intervals (CIs):
- Geometric mean titres (GMT) of anti-HA antibody titres
- Seroprotection rates (SPR)*
*SPR is defined as the percentage of vaccinees with serum HI titre ≥
1:40; usually accepted as indicating protection in at least 50% of the
vaccinees.
The following parameters will be calculated with 95% confidence
intervals (CIs):
- Seroconversion rates (SCR)*
- Mean geometric increase ([MGI] also known as the Seroconversion
factor [SCF])**
- Seroprotection power (SPP)***
*SCR is defined as the percentage of vaccinees with either a pre-vaccination
titre < 1:10 and a post-vaccination titre ≥ 1:40 or a pre-vaccination
titre ≥ 1:10 and at least 4-fold increase in post-vaccination
titre.
**MGI or SCF is defined as the fold increase in serum HI geometric mean
titres post-vaccination compared to Day 0.
***SPP is defined as the percentage of subjects who have a pre-vaccination
titre < 1:40 and a post-vaccination titre ≥ 1:40 |
|
E.5.1.1 | Timepoint(s) of evaluation of this end point |
At Day 0 and Day 21 post-vaccination for Geometric Mean Titres and
Seroprotection Rates.
At Day 21 post-vaccination for Seroconversion Rates, Mean Geometric
Increases (Seroconversion Factors), and Seroprotection Powers. |
|
E.5.2 | Secondary end point(s) |
1) Reactogenicity:
• Occurrence of solicited local and general symptoms
- Percentage, intensity and duration of solicited local symptoms
- Percentage, intensity, duration and relationship to vaccination of
solicited general symptoms
• Occurrence of unsolicited symptoms
- Percentage, intensity and relationship to vaccination of unsolicited
symptoms
• Occurrence of serious adverse events (SAEs)
- Percentage, intensity and relationship to vaccination of SAEs
2) Humoral immune response in terms of anti-HA antibodies against
each of the four vaccine influenza strains, in subjects aged 18-60 years
and >60 years who have and who have not received an influenza vaccine
during the 2 influenza seasons prior to season 2012/2013.
• The following parameters will be calculated with 95% CIs:
- GMTs of anti-HA antibody titres and SPRs, in subjects who have
and who have not received an influenza vaccine during the 2 influenza
seasons prior to season 2012/2013. |
|
E.5.2.1 | Timepoint(s) of evaluation of this end point |
• Solicited local and general symptoms: During a 4-day follow-up period
after vaccination (Days 0-3) (i.e. day of vaccination and 3 subsequent
days).
• Unsolicited symptoms: During a 21-day follow-up period after
vaccination (Days 0-20) (i.e. day of vaccination and 20 subsequent days.
• Serious adverse events: During the entire study period (Day 0-Day 21)
• Humoral immune response in subjects who have and who have not
received an influenza vaccine during the 2 influenza seasons prior to
season 2012/2013: At Day 0 and Day 21 post-vaccination |
