Influenza

Safety and Immunogenicity of Different Formulations of an MF59-Adjuvanted Influenza Vaccine in Older Adults

NCT04782323 | PHASE 2 | INTERVENTIONAL

This Phase 2, randomized, observer-blind, antigen and adjuvant dose-ranging Clinical study is evaluating different formulations of MF59-Adjuvanted Quadrivalent Subunit Inactivated Influenza Vaccine. Approximately 800 subjects are to be randomized into 1 of 8 possible treatment groups. Immunogenicity and safety will be assessed in the overall study population (adults ≥50 years and above) and in the age subgroups ≥50-64 years and ≥65 years. Data from this study will be used to select the optimal dose to be tested in the pivotal Phase 3 immunogenicity and safety study in older adults. Disclosure Statement: This is a parallel-group dose-ranging study with 8 arms that is participant, investigator and observer-blinded.
