H7N9 Mix and Match With AS03 and MF59 in Healthy Adults
A Phase II Randomized, Double-Blinded, Controlled Study in Healthy Adults to Assess the Safety, Reactogenicity, and Immunogenicity of a Monovalent Influenza A/H7N9 Virus Vaccine Administered at Different Dosages Given With and Without AS03 and MF59 Adjuvants

This Phase II randomized, double-blinded, controlled study in up to 1000 males and non-pregnant females, 19 to 64 years old, inclusive, who are in good health and meet all eligibility criteria is designed to provide data on an A/H7N9 vaccine made with HA antigen derived from the influenza A/Shanghai/2/2013 virus.

This Phase II randomized, double-blinded, controlled study in up to 1000 males and non-pregnant females, 19 to 64 years old, inclusive, who are in good health and meet all eligibility criteria is designed to provide data on an A/H7N9 vaccine made with HA antigen derived from the influenza A/Shanghai/2/2013 virus. The study aims to address several critical questions, including the safety, reactogenicity, and immunogenicity of a monovalent influenza A/H7N9 virus vaccine manufactured by Sanofi Pasteur: 1) two doses administered at different dosages (3.75, 7.5, or 15 mcg of HA/0.5 mL dose) given with AS03 adjuvant manufactured by GlaxoSmithKline Biologicals or without adjuvant (15 mcg of HA/0.5 mL dose and 45 mcg of HA/0.75 mL dose); and 2) a combination of two doses of the A/H7N9 vaccine (15 mcg of HA/0.5 mL dose) each administered with a different adjuvant (AS03 or MF59 manufactured by Novartis Vaccines and Diagnostics); and 3) two doses administered at 15 mcg of HA/0.5 mL dose given with MF59 adjuvant manufactured by Novartis Vaccines and Diagnostics.
