A Phase 2, Randomized, Stratified, Observer-Blind Clinical Study to Evaluate Safety and Immunogenicity of an MF59-Adjuvanted Quadrivalent Subunit Inactivated Influenza Vaccine in Older Adults
In Brief
A Phase 2 clinical trial evaluating Investigational aIIV4c, IIV4c, and 2 other interventions for Influenza and Human. Completed, enrolled 471 participants across 21 sites.
Detailed Summary
This Phase 2, randomized, observer-blind, active controlled clinical study is evaluating the safety and immunogenicity of the investigational MF59-Adjuvanted Quadrivalent Subunit Inactivated Influenza Vaccine. Approximately 480 subjects are to be randomized into 1 of 4 possible treatment groups (investigational Influenza Vaccine or licensed Quadrivalent Influenza Vaccine comparators) at 120 participants per group. Every participant will receive an influenza vaccine injection on Day 1 and will be followed up for approximately 6 months following injection. The primary immunogenicity analysis is based on Day 29 serum.
