Summary

Study FBP00005 is planned to be a translational Phase I, randomized, modified double-blind, active-controlled, multi-center study to be conducted in 2 stages in approximately 400 adults, 18 to 49 years of age and ≥ 60 years of age, in Australia. The purpose of the study is to evaluate the safety and immunogenicity of an influenza vaccine formulation composed of the WHO-recommended virus strains plus an additional H3 strain, compared to formulations containing a single strain from each influenza virus subtype. Younger adults 18 to 49 years of age will be enrolled in Stage 1 and offered study vaccine formulations at the standard dose. Adults ≥ 60 years of age in Stage 2 will be offered study vaccine formulations at a higher dose. Enrollment of participants in Stage 2 will occur after review of, and be guided by, safety and immunogenicity results from Stage 1. The study duration will be approximately 3 weeks.
