| NCT02369341 | Immunogenicity and Reactogenicity of GlaxoSmithKline (GSK) Biologicals' Quadrivalent Split Virion Influenza Vaccine Fluarix Tetra (2015 Season Southern Hemisphere) in Adults 18 Years of Age and Above | PHASE3 | COMPLETED | 121 | — | — | Apr 29, 2015 | Jun 3, 2015 | Oct 9, 2017 | 2 | Brazil |
Antibody titers were expressed as Geometric mean titers (GMTs). The vaccine strains assessed were Flu A/Christchurch/16/2010 (H1N1), Flu A/Switzerland/9715293/2013 (H3N2), Flu B/Phuket/3073/2013 (Yamagata) and Flu B/Brisbane/60/2008 (Victoria).
A seropositive subject was a subject whose HI antibody titer was greater than or equal to the assay cutoff value of 1:10. The vaccine strains assessed were Flu A/Christchurch/16/2010 (H1N1), Flu A/Switzerland/9715293/2013 (H3N2), Flu B/Phuket/3073/2013 (Yamagata) and Flu B/Brisbane/60/2008 (Victoria).
A seroprotected subject was defined as a vaccinated subject with a serum HI titer greater than or equal to (≥) 1:40 that usually is accepted as indicating protection in adults. The vaccine strains assessed were Flu A/Christchurch/16/2010 (H1N1), Flu A/Switzerland/9715293/2013 (H3N2), Flu B/Phuket/3073/2013 (Yamagata) and Flu B/Brisbane/60/2008 (Victoria).
A seroconverted subject was defined as a vaccinated subject with either a pre-vaccination HI titer less than (\<) 1:10 and a post-vaccination HI titer ≥1:40 or pre-vaccination HI titer ≥ 1:10 and at least a 4-fold increase in post-vaccination HI titer. The vaccine strains assessed were Flu A/Christchurch/16/2010 (H1N1), Flu A/Switzerland/9715293/2013 (H3N2), Flu B/Phuket/3073/2013 (Yamagata) and Flu B/Brisbane/60/2008 (Victoria).
SPP was defined as the number of vaccinated subjects with a pre-vaccination titer \< 1:40 and a post-vaccination titer ≥ 1:40. The vaccine strains assessed were Flu A/Christchurch/16/2010 (H1N1), Flu A/Switzerland/9715293/2013 (H3N2), Flu B/Phuket/3073/2013 (Yamagata) and Flu B/Brisbane/60/2008 (Victoria).
MGI also known as the seroconversion factor \[SCF\] was defined as the fold increase in serum HI GMTs post vaccination compared to pre-vaccination (Day 0). The vaccine strains assessed were Flu A/Christchurch/16/2010 (H1N1), Flu A/Switzerland/9715293/2013 (H3N2), Flu B/Phuket/3073/2013 (Yamagata) and Flu B/Brisbane/60/2008 (Victoria).
| Arm | Type | Description |
|---|---|---|
| Fluarix Tetra (Southern Hemisphere) Adult Group | EXPERIMENTAL | Subjects aged 18-60 years received 1 dose of Fluarix™ Tetra (Southern Hemisphere) vaccine at Day 0. The vaccine was administered intramuscularly in the deltoid of the non-dominant arm. |
