Last Updated: 2019-07-23

Results Overview

With respect to samples from HA Group 1-related studies (i.e., with H1N1, H5N1,and H9N2 pandemic, and quadrivalent inactivated seasonal, influenza vaccines, analysis was performed for measuring levels of anti-H18 antibody by ELISA for the subjects who received an AS vaccine in each study cohort and for the subjects in the FLU D-QIV-015 study cohort, aggregate variables were calculated with 95% CI for each treatment group within each study cohort. Geometric mean concentrations (GMCs) were expressed in Elisa Unit per milliliter (EU/mL)

• Recruitment status: COMPLETED
• Target enrollment: 414 participants
• Primary outcome timeframe: At Day 42 (Post-vaccination 2) and final timepoint (for persistence) (i.e., Day 385)

Population: All subjects from each study cohort with available results were included in the analysis for this study. All subjects selected were from the ATP cohort for immunogenicity of respective primary studies.

With respect to samples from HA Group 1-related studies (i.e., with H1N1, H5N1,and H9N2 pandemic, and quadrivalent inactivated seasonal, influenza vaccines, analysis was performed for measuring levels of anti-H1 stalk antibody by MN for all subjects who received an AS vaccine in each study cohort, aggregate variables were calculated with 95% CI for each treatment group within each study cohort. seronegative subjects = titer < 10 1/DIL for anti-H1 stalk MN prior to vaccination seropositive subjects = titer ≥ 10 1/DIL for anti-H1 stalk MN prior to vaccination. 4-fold increase defined as: For initially seronegative subjects, antibody titer ≥ 20 1/DIL at post-vaccination; For initially seropositive subjects, antibody titer at post-vaccination ≥ 4-fold the pre-vaccination antibody titer. The ≥4-fold increases were only calculated relative to baseline.

Percentage of subjects with at least 4-fold increase to anti-H1 stalk ELISA was calculated with 95% CI at each specified time point. seronegative subjects = concentration < 66 EU/mL for anti-H1 stalk ELISA prior to vaccination. seropositive subjects = concentration ≥ 66 EU/mL for anti-H1 stalk ELISA prior to vaccination. 4-fold increase defined as: For initially seronegative subjects, antibody concentration ≥ 132 EU/mL at post-vaccination. For initially seropositive subjects, antibody concentration at post-vaccination ≥ 4-fold the pre-vaccination antibody concentration.
