Comparison of Safety, Tolerability and Immunogenicity of Influenza Vaccines in Adults and Elderly

Phase 3
Completed
Conditions
Influenza
Interventions
Biological: Cell culture derived influenza vaccine
Biological: egg-derived influenza subunit vaccine
Registration Number
NCT00306527
Lead Sponsor
Novartis Vaccines
Brief Summary

The purpose of the study is to evaluate safety, tolerability and immunogenicity (in a subset) following a dose of a trivalent subunit influenza vaccine produced either in mammalian cells or in embryonated hen eggs, in healthy adult and elderly subjects who received either vaccine one year before (2004) in the study V58P4.

Primary Outcome Measures
NameTimeMethod
Number of Subjects Reporting Solicited Adverse Events After One Dose of Cell Culture-derived or the Egg-derived Influenza VaccineDay 1 to Day 7 postvaccination

To assess the safety and tolerability in terms of number of adult and elderly subjects reporting solicited adverse events following one dose of the cTIV or the TIV vaccine .

Secondary Outcome Measures
NameTimeMethod
Six-months Safety Data of Subjects After One Dose of Cell Culture Derived or Egg-derived Influenza VaccineUp to 6 months postvaccination

To collect additional safety data for 6 months after vaccination with one dose of cell culture derived or egg-derived influenza vaccine in terms of serious adverse events (SAEs), adverse events (AEs) necessitating a physician's visit and/or resulting in premature subject's withdrawal from study.

Geometric Mean Titers (GMTs) After One Dose of Cell Culture-derived or the Egg-derived Influenza Vaccine in Adult and Elderly SubjectsDay 22 postvaccination

The haemagglutinin inhibition (HI) antibody titer response following one 0.5 mL dose of either cell derived (cTIV) or egg-derived vaccine (TIV) in adult and elderly subjects is reported as GMTs.

The HI GMTs were evaluated using egg-derived antigen assay.

Geometric Mean Ratios (GMRs), After One Dose of the Cell Culture-derived or the Egg-derived Influenza Vaccine in Adult and Elderly SubjectsDay 22 postvaccination

Immunogenicity was assessed in terms of GMR in adult and elderly subjects following one 0.5ml dose of either the cTIV vaccine or the TIV vaccine, according to the CHMP criteria.

The European licensure (CHMP) criteria was met if the mean geometric increase (GMR, day 22/day 1) in HI antibody titer is \>2.5 for adults and \>2.0 for elderly subjects.

Percentages of Adult and Elderly Subjects Achieving HI Titers ≥ 40 After One Dose of the Cell Culture-derived or the Egg-derived Influenza Vaccine.Day 22 postvaccination

Immunogenicity was assessed in terms of percentages of adult and elderly subjects achieving HI titers≥40,after one dose of either the cTIV vaccine or the TIV vaccine.

European (CHMP) criteria is met if the percentage of subjects achieving HI titers ≥ 40 is \> 70% for adults and \>60% for elderly.

Percentages of Adult and Elderly Subjects With Seroconversion or Significant Increase in HI Antibody Titers After One Dose of Cell Culture-derived or the Egg-derived Influenza Vaccine.Day 22 postvaccination

Immunogenicity was assessed in terms of percentages of adult and elderly subjects showing seroconversion or significant increase in HI antibody titers after one dose of cell culture-derived or the egg-derived influenza vaccine.

Seroconversion or significant increase as per European Licensure (CHMP) criteria is defined as percentage of subjects with a prevaccination HI titer \<10 to a postvaccination titer ≥ 40 for adults and ≥ 30 for elderly. Significant increase is defined as percentage of subjects with a prevaccination HI titer ≥ 10 and a ≥ 4-fold increase in postvaccination HI antibody titer.
