E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
1. To assess persistence of antibody titers 17-18 months after primary immunization with
two 0.5mL intramuscular (IM) doses of FLUAD-H5N1 influenza vaccine containing
either 7.5ᄉg or 15ᄉg of H5N1 influenza antigen, as measured by Hemagglutination
Inhibition (HI), Single Radial Hemolysis (SRH), and Microneutralization (MN) test.
2. To evaluate the safety of the administration of one 0.5mL IM booster dose of FLUADH5N1
influenza vaccine containing 7.5ᄉg of H5N1 influenza antigen 17-18 months after
primary immunization. |
|
E.2.2 | Secondary objectives of the trial |
1. To assess immunogenicity of one 0.5mL IM booster dose of FLUAD-H5N1 influenza
vaccine containing 7.5ᄉg of H5N1 influenza antigen (A/Turkey/Turkey), as measured by
HI and SRH test in compliance with the requirements of the current European Union
recommendations (CPMP/BWP/214/96).
2. To assess immunogenicity of one 0.5mL IM booster dose of FLUAD-H5N1 influenza
vaccine containing 7.5 ᄉg of H5N1 influenza antigen, as measured by MN test. |

able to give written informed consent prior to study entry
2. Previously participating in study V87P1, but did not receive the booster dose on
day 202
3. Able to comply with all the study requirements
4. In general good health as determined by:
a. Medical history
b. Physical examination
c. Clinical judgment of the investigator |
|
E.4 | Principal exclusion criteria |
1. Any serious disease such as:
a. Cancer (except for benign or localized skin cancer and non metastatic prostate
cancer not presently treated with chemotherapy)
b. Autoimmune disease (including rheumatoid arthritis)
c. Advanced atherosclerotic disease or complicated diabetes mellitus
d. Chronic obstructive pulmonary disease (COPD) that requires oxygen therapy
e. Acute or progressive hepatic disease
f. Acute or progressive renal disease
g. Congestive heart failure
2. Hypersensitivity to eggs, chicken protein, chicken feathers, influenza viral protein,
neomycin or polymyxin or any other component of the vaccine
3. History of neurological symptoms or signs, or anaphylactic shock following
administration of any vaccine
4. Known or suspected (or have a high risk of developing) impairment/ alteration of
immune function (excluding that normally associated with advanced age) resulting,
for example, from:
a. Receipt of immunosuppressive therapy (any parenteral or oral corticosteroid or
cancer chemotherapy/radiotherapy) within the past 60 days and for the full length
of the study
b. Receipt of immunostimulants
c. Receipt of parenteral immunoglobulin preparation, blood products and/or plasma
derivates within the past 3 months
d. Suspected or known HIV infection or HIV-related disease
5. All females of childbearing potential who refuse to use an acceptable method of birth
control for 21 days after the booster vaccination and/or who refuse to perform a urine
pregnancy test prior to vaccination. Adequate contraception is defined as hormonal
(e.g., oral, injection, transdermal patch, implant, cervical ring), barrier (e.g., condom
with spermicide or diaphragm with spermicide), intrauterine device (e.g., IUD), or
monogamous relationship with vasectomized partner who has been vasectomized for
6 months or more prior to the subject's study entry
6. Pregnant or breastfeeding
7. Receipt of another vaccine or any investigational agent within the past 4 weeks
8. Experience of any acute disease or infections requiring systemic antibiotic or antiviral
therapy (chronic antibiotic therapy for urinary tract prophylaxis is acceptable) within
the past 7 days
9. Experience of fever (i.e., axillary temperature 38ᄚC) within the past 3 days
10. Participation in another clinical study
11. Surgery planned during the study period
12. Any condition which, in the opinion of the investigator, might interfere with the
evaluation of the study objective |

E.5 End points |
E.5.1 | Primary end point(s) |
The measures of immunogenicity, collected for all evaluable subjects include:
- Geometric mean titers/areas (GMTs/GMAs) on days 382, 389, and 403 and GMRs for days 389 and 403 versus Day 382 as determined by HI, SRH, and MN.
- Percentage of subjects achieving seroconversion1 or significant increase in antibody titer/area2 on days 389, and 403 as measured by HI and SRH.
- Percentage of subjects with titers 20, titers 40, titers 80, on days 382, 389 and 403 and percentage of subjects with at least a four-fold rise in titer on days 389 and403 as determined by MN.
- Percentage of subjects achieving a titer 40/ area 25 mm2 on days 382, 389, and 403 as determined by HI and SRH. |
