Summary

This is a Phase I cohort-randomized, double-blind, controlled trial designed to assess the safety, reactogenicity, and immunogenicity of a monovalent inactivated influenza A/H5N8 virus vaccine administered at different dosages (3.75 and 15 mcg of HA per dose) given with or without AS03 or MF59 adjuvants. This study will be conducted at 6 sites and enroll 150 (up to 380) males and non-pregnant females, 19 to 64 years old, inclusive who are in good health and meet all eligibility criteria. The entire study duration is approximately 24 months and each subject participation duration is approximately 13 months. The primary objectives are: 1) To assess the safety and reactogenicity of a monovalent inactivated influenza A/H5N8 virus vaccine following receipt of two doses administered intramuscularly at different dosages (3.75 and 15 mcg of HA per dose) given with or without AS03 or MF59 adjuvants approximately 21 days apart. 2) To assess the serum HAI and Neut antibody responses to a monovalent inactivated influenza A/H5N8 virus vaccine following receipt of two doses administered intramuscularly at different dosages (3.75 and 15 mcg of HA per dose) given with or without AS03 or MF59 adjuvants approximately 21 days apart.
