NCT01498718

Brief Summary

This is a Phase 1b, randomized study in healthy younger (18-50 years) and older (51-70 years) adults to evaluate the safety, tolerability, and immunogenicity of a prime-boost vaccination regimen with an investigational plasmid DNA vaccine directed towards the 2011/12 influenza vaccine strains as a prime followed 36 weeks later by the 2012/13 influenza trivalent inactivated vaccine (TIV) as the booster injection, as compared to placebo prime followed by the 2012/13 seasonal TIV. The hypothesis is that the DNA vaccine will be safe for human administration and that the DNA vaccine prime-TIV boost schedule will elicit a better immune response than the seasonal TIV alone.

Outcome Measures

Primary Outcomes (7)

  • Frequency of subjects per Group of serious adverse events (SAEs)

    Serious adverse events included any untoward medical occurrence that resulted in death; was life threatening; was a persistent/significant disability/incapacity; required non-elective in-patient hospitalization or prolongation thereof; resulted in a congenital anomaly/birth defect; may have jeopardized the subject or required intervention to prevent one of these outcomes. Association to vaccination was determined by a study clinician licensed to make medical diagnoses.

    Day 0 (after injection) to Week 60 (Visit 07)

  • Frequency of Subjects per Group of Solicited Local Reactions After First Study Injection

    Frequency and severity of solicited injection site reactions following first study injection (vaccine group compared to placebo group).

    Within 7 days after first vaccination

  • Frequency of Subjects per Group Reporting Solicited Local Reactions After TIV injection

    Frequency and severity of solicited injection site reactions following the TIV booster injection by Group.

    Within 7 days after TIV injection

  • Frequency of Subjects per Group Reporting Solicited Systemic Reactions After First Study Injection

    Frequency and severity of solicited systemic reactions following first study injection (vaccine group compared to placebo group).

    Within 7 days after first study injection

  • Frequency of Subjects per Group Reporting Solicited Systemic Reactions After TIV injection

    Frequency and severity of solicited systemic reactions following TIV injection.

    Within 7 days after TIV injection

  • Frequency by group of all unsolicited adverse events (AEs) after first study injection.

    Frequency of adverse events (AEs) during 28 days after first study injection (vaccine as compared to placebo groups).

    Through Day 28 after first injection

  • Frequency by group of all unsolicited adverse events (AEs) after TIV vaccination.

    Frequency of unsolicited adverse events (AEs) during 28 days after TIV vaccination by group.

    Through Day 28 after second vaccincation

Secondary Outcomes (2)

  • Proportion of subjects per group with an Hemagglutination Inhibition (HAI) titer ≥ 1:40 or four-fold greater than baseline (Day 0) compared to those who received the seasonal influenza TIV alone.

    Week 40 (4 weeks after TIV)

  • Proportion of subjects by group with a four-fold or greater rise from baseline (Day 0) and Week 40 in specific H1, H3 and B neutralizing antibodies

    Week 40 (4 weeks after TIV)

VRC-FLUDNA061-00-VP is composed of 3 closed-circular DNA plasmids that encode for the hemagglutinin (HA) from the following 3 strains: A/California/04/2009 (H1N1); A/Perth/16/2009 (H3N2), and B/Brisbane/60/2008. DNA vaccine vials will be supplied at 4 mg/mL and each dose will be 1 mL.
