NCT01147068

Brief Summary

The purpose of this study is to investigate the safety and immunogenicity of a recombinant hemagglutinin (rHA) influenza vaccine derived from A/Indonesia/05/2005 (H5N1) administered at 4 dose levels in adjuvanted (GLA-SE) rHA formulations and 2 dose levels in unadjuvanted rHA formulations.

Outcome Measures

Primary Outcomes (1)

  • Evaluation of Immunogenicity Measured by Seroconversion Rates of PanBlok With and Without Adjuvant Compared to Placebo in Healthy Adults 18-49 Years of Age.

    Immunogenicity was assessed by measuring the percentage of subjects in each group exhibiting seroconversion on Day 42. The treatment groups that received adjuvanted rHA were evaluated against non-adjuvanted rHA and placebo groups for whether they demonstrated seroconversion rates and 95% confidence intervals that met regulatory criterion for licensure.

    42 Days

Secondary Outcomes (2)

  • Evaluation and Comparison of Immunogenicity From Geometric Mean Titers of PanBlok With and Without Adjuvant and Placebo in Healthy Adults 18-64 Years of Age.

    Day 0, and Day 42

  • Serologic Response Rates at Day 21 Using PanBlok With and Without Adjuvant and Placebo in Healthy Adults 18-64 Years of Age

    21 Days

Limitations and Caveats

The absence of a treatment group receiving a SE- or GLA-alone adjuvanted vaccine formulation is a limitation to the study conclusion.
