Seasonal Influenza DNA Vaccine Prime With Trivalent Inactivated Vaccine (TIV) Boost Compared to TIV Alone
Double-Blind, Randomized Phase 1b Study of 2011/12 Influenza Investigational DNA Vaccine, VRC-FLUDNA061-00-VP, Followed by 2012/13 Trivalent Inactivated Vaccine (TIV) Compared to 2012/13 TIV Alone in Healthy Adults

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)
Study Arms (4)
Group 1A (18-50 yrs): DNA vaccine + TIV
EXPERIMENTALHA DNA Vaccine (VRC-FLUDNA061-00-VP) at Day 0 and licensed TIV at Week 36
Group 2A (51-70 yrs): DNA vaccine + TIV
EXPERIMENTALHA DNA Vaccine (VRC-FLUDNA061-00-VP) at Day 0 and licensed TIV at Week 36
Group 1B (18-50 yrs): TIV only
PLACEBO COMPARATORPhosphate buffered saline (PBS) on Day 0 + TIV at Week 36
Group 2B (51-70 yrs): TIV only
PLACEBO COMPARATORPhosphate buffered saline (PBS) on Day 0 + TIV at Week 36
Interventions
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.
