Brief summary

This is a first in man study evaluating the tolerability and immunogenicity of BIPCV/IMX (V512) at increasing concentrations of influenza viral peptides A/M2+B/HA0 peptides and IMX, a saponin-based adjuvant.

Interventions

BIOLOGICALV512

Subjects received 1 of 8 formulations of the BIPCV/IMX vaccine (V512) in a 3-dose regimen of 0.5 mL injections at Day 1, Month 2, and Month 6: 1\) 0.5 mcg each of A/M2 and B/HA0 peptides with 225 mcg MAA and 20 mcg IMX; 2) 0.5 mcg each of A/M2 and B/HA0 peptides with 225 mcg MAA and 60 mcg IMX; 3) 5 mcg each of A/M2 and B/HA0 peptides with 225 mcg MAA and 20 mcg IMX; 4) 5 mcg each of A/M2 and B/HA0 peptides with 225 mcg MAA and 60 mcg IMX; 5) 5 mcg each of A/M2 and B/HA0 peptides with 225 mcg MAA and 100 mcg IMX; 6) 20 mcg each of A/M2 and B/HA0 peptides with 225 mcg MAA and 20 mcg IMX; 7) 20 mcg each of A/M2 and B/HA0 peptides with 225 mcg MAA and 60 mcg IMX; 8) 20 mcg each of A/M2 and B/HA0 peptides with 225 mcg MAA and 100 mcg IMX;

BIOLOGICALComparator: Placebo to V512

Subjects received placebo to the BIPCV/IMX vaccine (V512) in a 3-dose regimen of 0.5 mL injections at Day 1, Month 2, and Month 6.
