Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The hypothesis for this trial is that the incidence of a pre-defined composite of common systemic hypersensitivity adverse events for Flublok recipients is non-inferior to that reported for licensed IIV recipients. Another hypothesis is that the safety and reactogenicity of Flublok is clinically acceptable, i.e. consistent with the overall safety profiles previously observed with Flublok and with the licensed comparator.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

The Advisory Committee on Immunization Practices (ACIP) recommends that all people aged 6 months and older be immunized to prevent influenza. Currently the only approved influenza vaccine across the entire age group is inactivated influenza vaccine (IIV). A Biologics Licensing Application (BLA) for Flublok was approved by the FDA for influenza immunization of adults 18-49 years of age. Additional safety and, ultimately efficacy, data is needed to support use in adults ≥50 years of age, an important age group as adults ≥65 years of age are among those at increased risk of influenza complications.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

Flublok

Flublok containing 3x45µg (135µg total) of recombinant hemagglutinin (rHA) derived from influenza A/H1N1 and A/H3N2 and influenza B viruses in a total volume of 0.5 mL

Group Type ACTIVE_COMPARATOR

Flublok

Intervention Type BIOLOGICAL

A Biologics Licensing Application (BLA) for Flublok was approved by the FDA for influenza immunization of adults 18-49 years of age. Flublok is produced using recombinant technology under serum-free conditions.

Afluria

Afluria, containing 3x15µg (45µg total), of trivalent, inactivated influenza vaccine (licensed IIV) containing influenza antigen derived from A/H1N1 and A/H3N2 and influenza B viruses in a total volume of 0.5 mL

Group Type PLACEBO_COMPARATOR

Afluria

Intervention Type BIOLOGICAL

Afluria is approved for use in persons 5 years of age and older and is produced by inactivation and disruption of live influenza virus grown in embryonated chicken eggs.

4. Plans to participate in any investigation involving an investigational product during this study.
5. Pre-existence of atopic dermatitis or any other cutaneous disorder that could complicate the evaluation of potential primary endpoints.
6. Any clinical or social circumstance that in the opinion of the investigator could interfere with compliance with study procedures or interfere with the interpretation of clinical data.
