Clinical Trial Summary

The present study is designed to evaluate the safety and immunogenicity of trivalent, surface antigen, inactivated influenza vaccine in 2 age cohorts: 18 to ≤60 years and ≥61 years.

For the immunogenicity endpoint the antibody response to each influenza vaccine antigen will be evaluated by means of Single Radial Hemolysis (SRH) or Hemagglutination Inhibition (HI) at approximately 21 days post vaccination.

The vaccine composition will be based on the WHO recommended influenza strains for the 2015 Southern Hemisphere vaccine, and the data from this study are intended to support the use of this vaccine in future influenza seasons if the recommended vaccine composition remains the same.

Outcome

Type Measure Description Time frame Safety issue
Primary Percentages of Subjects With Single Radial Hemolysis (SRH) Areas =25mm^2, Against Each of Three Vaccine Strains After Receiving One Dose of TIV. Immunogenicity was assessed in terms of percentages of subjects in both age groups with SRH areas =25mm^2 against each of the three vaccine strains, three weeks after receiving one dose of TIV.
The related European Committee for Medicinal Products for Human Use (CHMP) criterion for the assessment of immunogenicity is met if the percentage of subjects achieving post vaccination SRH areas = 25mm^2 is >70% for adults aged 18 to =60 years and >60% for subjects aged =61 years.
Day 1 and Day 22 post vaccination No
Primary Percentages of Subjects With Seroconversion or Significant Increase in SRH Area, Against Each of Three Vaccine Strains After Receiving One Dose of TIV. Immunogenicity was assessed in terms of percentages of subjects in both age groups achieving seroconversion or significant increase by SRH area against each of the three vaccine strains, three weeks after receiving one dose of TIV.
Seroconversion is defined as percentage of subjects with a pre vaccination SRH area = 4mm^2 achieving a post vaccination SRH area = 25mm^2. Significant increase is defined as percentage of subjects with a pre-vaccination SRH area > 4mm^2 achieving at least 50% increase in post vaccination SRH area.
The related European (CHMP) criterion for the assessment of immunogenicity is met if >40% for adults aged 18 to =60 years and >30% for subjects aged =61 years achieve seroconversion or significant increase in post-vaccination SRH areas.
Day 22 post vaccination No
Primary Geometric Mean Ratio (GMR) of Post Vaccination Versus Pre Vaccination Geometric Mean Area (GMAs), After One Dose of TIV. The antibody responses were evaluated in terms of GMRs of post vaccination GMAs to pre vaccination GMAs against each of the three vaccine strains, three weeks after receiving one dose of TIV.
The related European (CHMP) criterion for the assessment of immunogenicity is met if the GMR day 22/day 1 is >2.5 for adults aged 18 to =60 years and > 2.0 in for subjects aged =61 years.
Day 22/ Day1 post vaccination No
Primary Percentages of Subjects With Haemagglutination Inhibition (HI) Titers =40, Against Each of Three Vaccine Strains After Receiving One Dose of TIV. Immunogenicity was assessed in terms of percentages of subjects in both age groups with HI titers =40, against each of the three vaccine strains, three weeks after receiving one dose of TIV.
The related European (CHMP) criterion for the assessment of immunogenicity is met if the percentage of subjects achieving HI titers = 40 is >70% for adults aged 18 to =60 years and >60% for subjects aged =61 years.
Day 1 and Day 22 post vaccination No
Primary Percentages of Subjects With Seroconversion or Significant Increase in HI Antibody Titers After Receiving One Dose of TIV. Immunogenicity was assessed in terms of percentages of subjects in both age groups achieving seroconversion or significant increase in HI antibody titers after receiving one dose of TIV.
Seroconversion is defined as percentage of subjects with a pre vaccination HI titer <10 and a post vaccination titer =40. Significant increase is defined as percentage of subjects with a pre vaccination HI titer =10 and at least a 4-fold increase in post vaccination HI antibody titers.
The related European (CHMP) criterion for the assessment of immunogenicity is met if >40% for adults aged 18 to =60 years and >30% for subjects aged =61 years achieve seroconversion or significant increase in post-vaccination HI titers.
Day 22 post vaccination No
Primary GMR of Post Vaccination Versus Pre Vaccination HI Antibody Titers, After Receiving One Dose of TIV. The antibody responses following one vaccination of TIV were evaluated in terms of GMRs of post vaccination against pre vaccination geometric mean HI titers against each of the three vaccine strains, three weeks after receiving one dose of TIV.
The related European (CHMP) criterion for the assessment of immunogenicity is met if the GMR day 22/day 1 is >2.5 for adults aged 18 to =60 years and > 2.0 for subjects aged =61 years.
Day 22/Day 1 post vaccination No
Primary Number of Subjects Reporting Local and Systemic Solicited Adverse Events (AEs) After Receiving One Dose of TIV. The number of adult and elderly subjects reporting solicited local and systemic AEs and other solicited AEs after receiving one dose of TIV are reported. Day 1 to Day 4 post vaccination (including 30 mins) No

Primary Number of Subjects Reporting Unsolicited AEs After Receiving One Vaccination of TIV. The number of subjects in both age groups reporting any unsolicited AEs (between Day 1 to 4), serious adverse events (SAEs), medically attended AEs, AEs leading to premature withdrawal (Day 1 to Day 22), after receiving one vaccination of TIV is reported. Day 1 to Day 22 post vaccination No
