Pediatric Safety and Immunogenicity Study of Cell-Culture Derived and Egg-based Subunit Influenza Vaccines in Healthy Children and Adolescents

20. Oktober 2015 aktualisiert von: Novartis

A Combined Phase II/III, Observer-Blind, Randomized, Multi-center Study to Evaluate Safety, Tolerability and Immunogenicity of Trivalent Subunit Influenza Vaccines, Produced Either in Mammalian Cell Culture or in Embryonated Hen Eggs, in Healthy Children and Adolescents

The present study is the first study designed to evaluate safety, tolerability and immunogenicity of the cell culture-derived influenza vaccine in healthy children and adolescents aged 3 to 17 years. A step-down approach is utilized in which reactogenicity and safety will be assessed in children and adolescents 9 to 17 years of age (Cohort 1) prior to enrolling additional children and adolescents 9 to 17 years of age (Cohort 2) and children 3 to 8 years of age (Cohort 3).

Geometric Mean Titers of the Cell Culture-derived Vaccine Compared With the Egg-derived Vaccine in 3 to 8 Year-old Children
Zeitfenster: Day 50 post vaccination

To demonstrate non-inferiority of the post vaccination hemagglutination inhibition (HI) geometric mean titer (GMT) of the cell culture-derived influenza (cTIV) vaccine to the corresponding GMT of the egg-derived (eTIV) influenza vaccine, for all three strains, after two injections administered four weeks apart to a subset of children 3 to 8 years of age.

GMTs were evaluated using two assays, HI egg derived antigen assay and HI cell derived antigen assay.
