Study of Quadrivalent Influenza Vaccine Among Adults

Completed · Phase 3

Conditions studied: Influenza

In brief

The aim of the study is to evaluate a prototype quadrivalent influenza vaccine (QIV), the licensed 2010-2011 trivalent influenza vaccine (TIV) containing the primary B strain, and the investigational TIV containing the alternate B strain in adult subjects. Primary Objective: * To demonstrate non-inferiority of antibody responses to QIV compared with licensed 2010-2011 TIV (containing the primary B strain) and investigational TIV (containing the alternate B strain) as assessed by geometric mean titer (GMT) ratios for each of the four virus strains separately among subjects 65 years of age and older Observational Objective: * To describe the safety profiles of TIV among subjects 18 years of age and older and QIV in subjects 65 years and older, as assessed by solicited injection site and systemic adverse events (AEs) collected for 7 days post-vaccination, unsolicited adverse events collected from 21 days post-vaccination, and adverse events of special interest and serious adverse events (SAEs) collected from Visit 1 to Visit 2.

• Receipt of any influenza vaccine since 01 August 2010 (including 2009 H1N1 monovalent vaccine).
• Known systemic hypersensitivity to any of the vaccine components, or history of a life-threatening reaction to the vaccine(s) used in the trial or to a vaccine containing any of the same substances.
• Receipt of blood or blood-derived products in the past 3 months, which might interfere with assessment of the immune response.
• Thrombocytopenia, bleeding disorder, or receipt of anticoagulants contraindicating intramuscular vaccination.
• Any condition that in the opinion of the Investigator would pose a health risk to the subject if enrolled or could interfere with the evaluation of the vaccine.
• Personal history of Guillain-Barré Syndrome (GBS).
• Known or suspected congenital or acquired immunodeficiency; or receipt of immunosuppressive therapy such as anti-cancer chemotherapy or radiation therapy within the preceding 6 months; or long-term systemic corticosteroid therapy (prednisone or equivalent for more than 2 consecutive weeks within the past 3 months).
• Any chronic illness that, in the opinion of the Investigator, is not well controlled or that may interfere with trial conduct or completion or with assessment of adverse events.
• Known seropositivity for human immunodeficiency virus (HIV), hepatitis B, or hepatitis C.
• Deprived of freedom by an administrative or court order, or in an emergency setting, or hospitalized involuntarily.
• Current alcohol or drug use that, in the opinion of the Investigator, might interfere with the ability to comply with trial procedures.
