- Conditions
- Influenza
- Interventions
- Biological: GSK Bio's influenza vaccine GSK2186877ABiological: Fluarix TM
- Registration Number
- NCT00753272
- Lead Sponsor
- GlaxoSmithKline
- Brief Summary
The purpose of this study is to evaluate the efficacy of GlaxoSmithKline Biologicals' influenza vaccine GSK2186877A in adults 65 year of age and older. The study design is divided in two surveillance phases: one passive phase along the study during the influenza season and one active surveillance phase during the influenza peak season.
- Detailed Description
This Protocol Posting has been updated according to Protocol Amendment 3, Sep 2009.
After the analyses for this study were completed, questions arose regarding the integrity of study data from a single study site in Romania, which enrolled 102 subjects in the trial. Because evaluation of data from this site did not reveal irregularities when compared with overall study data and because GSK has no current plans to use the data from the study in support of any regulatory filings, they were not excluded from the analyses reflected in this results summary.

Group Intervention Description FluNG Group GSK Bio's influenza vaccine GSK2186877A subjects received 2 doses (1 dose per season) of FluNG vaccine during the Northern Hemisphere (NH) vaccination periods. One dose at Day 0 of the Year 1 and one dose at Day 0 of the Year 2 (= Day 365 Year 1). Fluarix Group Fluarix TM subjects received 2 doses (1 dose per season) of Fluarix™ vaccine during the Northern Hemisphere (NH) vaccination periods. One dose at Day 0 of the Year 1 and one dose at Day 0 of the Year 2 (= Day 365 Year 1).
- Primary Outcome Measures
Name Time Method Serum Hemagglutination-inhibition (HI) Antibody Titers, Against Each of the 3 Vaccine Influenza Strains, in the FluNG Groups. At Days 0 (pre-vaccination Dose 1) and 21 (post-vaccination Dose 1) of the first year (2008/2009) of the study Vaccine strains assessed were A/Brisbane/59/2077, A/Uruguay/716/2007 and B/Brisbane/3/2007. Titers were expressed as geometric mean titers calculated on all subjects in the lot-to-lot subset of subjects.
Number of Subjects Reporting Polymerase Chain Reaction (PCR)-Confirmed Influenza A and/or B Infection. After the first dose during the corresponding surveillance period (from mid November 2008 to the end of April 2009 (end of influenza season)) Occurrence of PCR-confirmed influenza A and/or B infection, due to any matching or drift influenza strain relative to the vaccine strains (i.e. not emerging novel human influenza strain like H1N1v). PCR-confirmed influenza (PCI) was defined as an episode of influenza-like illness (ILI) occurring after the administration of the study vaccine for which a nasal and throat swab specimen yields influenza virus A and/or B by reverse transcription polymerase chain reaction (RT-PCR) analysis.
