Immunogenicity, Safety and Tolerability of Two Doses of Adjuvanted and Non-adjuvanted Swine Origin A/H1N1 Monovalent Influenza Vaccine in Healthy Subjects 18 or More Years of Age
A Randomized, Single-blind, Dose-Ranging, Study to Evaluate Immunogenicity, Safety and Tolerability of Different Formulations of Adjuvanted and Non Adjuvanted Egg-Derived, Inactivated Novel Swine Origin A/H1N1 Monovalent Subunit Influenza Virus Vaccine in Healthy Subjects 18 or More Years of Age

Brief Summary
This present study, randomized, single-blind, dose-ranging, multicenter study, will evaluate immunogenicity, safety and tolerability of two doses of an adjuvanted and not-adjuvanted new swine-origin influenza A/H1N1 virus monovalent subunit vaccine in healthy adult and elderly subjects. A booster dose will be administered 12 months after the first vaccination.

Outcome Measures
Primary Outcomes (1)
To identify the preferred vaccine formulation, dosage (antigen & adjuvant), schedule (one or two administrations) of the H1N1 sw monovalent vaccine in adults
43 days after first vaccination
Secondary Outcomes (1)
To evaluate immunogenicity against A/California H1N1sw strain after booster dose of egg-derived seasonal trivalent, MF59 adjuvanted vaccine Fluad, recommended for 2010/2011 season, administered 12 months after primary course according to CHMP criteria
3 weeks after booster vaccination
Study Arms (3)
low dose of antigen + low dose of adjuvant
EXPERIMENTALhigh dose of antigen + high dose of adjuvant
EXPERIMENTALhigh dose of antigen
EXPERIMENTALInterventions
This trial will be performed at multiple study sites in a population of healthy adults and elderly. Subjects will be randomized to receive two IM injections of low dose of antigen \& adjuvant,or high dose of antigen \& adjuvant, or high dose of antigen, according to the study groups
Eligibility Criteria
You may qualify if:
- Males and females 18 years of age and above on the day of enrollment;
- Individuals in good health
- Individuals are able to comply with all study procedures
- Willingness to allow for serum samples to be stored beyond the study period, for potential additional future testing to better characterize immune response.
You may not qualify if:
- Individual not able to comprehend and to follow all required study procedures;
- History or any illness that might interfere with the results of the study or pose additional risk to the subjects due to participation in the study;
- Any serious chronic or progressive disease according to judgment of the investigator
- History of any anaphylaxis, serious vaccine reactions, to any excipients.
- Adjuvanted influenza vaccine or documented confirmed or suspected influenza disease within 3 months prior to Day 1;
- Receipt of another investigational agent within 4 weeks prior to enrollment, or before completion of the safety follow-up period in this or in another study; unwilling to refuse participation in another clinical study through the end of this study;
- Any other vaccines within 4 weeks prior to enrollment or who are planning to receive any vaccine within 4 weeks from the study vaccines; only exception being plain seasonal influenza vaccines which are allowed until 1 week prior to and after 1 week study vaccinations.
- Receipt of blood, blood products and/or plasma derivatives or any parenteral immunoglobulin preparation in the past 12 weeks;
- Axillary temperature ≥ 38°C or oral temperature ≥ 38.5°C within 3 days of intended study vaccination;
- Known or suspected impairment/alteration of immune function, for example resulting from a receipt of immunosuppressive therapy within 60 days prior to Visit 1;
- History of progressive or severe neurological disorders;
- Surgery planned during the study period that in the Investigator's opinion would interfere with the study visits schedule;
- Female of childbearing potential, not used any acceptable contraceptive methods for at least 2 months prior to study entry;
- Female pregnant or nursing (breastfeeding) mothers or females of childbearing potential do not plan to use acceptable birth control measures during the first 3 weeks after vaccination;
- Members of the research staff or their relatives.
