NCT01702857

Brief Summary

This is a first time in humans (FTiH) study designed to assess the experimental TDENV-PIV vaccine in a predominantly dengue-primed adult population. The study is designed to afford a first time in humans (FTiH) safety and immunogenicity assessment of three TDENV-PIV vaccine candidates, each formulated with a different adjuvant: either aluminum hydroxide, AS01E or AS03B (adjuvants used in GSK Biologicals' hepatitis B candidate vaccine, malaria candidate vaccine and pandemic flu vaccine, respectively). Each vaccine candidate will contain 1 µg of purified virus antigen per each of the four DENV types. Additionally, the study will evaluate an alum adjuvanted TDENV-PIV vaccine candidate containing 4 µg of purified virus antigen per each of the four DENV types. The control group will receive a saline placebo. All experimental vaccinations will be administered according to a 2-dose schedule, 28 days apart. There is a parallel FTiH study that is conducted in the United States in a dengue-naive population using the same investigational vaccines.

Outcome Measures

Primary Outcomes (2)

  • Safety and reactogenicity of various TDENV-PIV formulations from Day 0 through 28 days after the second dose (Day 0 - Day 56)

    Safety and Reactogenicity: * Occurrence, intensity and relationship to vaccination of solicited local and general adverse events (AEs) during the 7-day follow-up period post each vaccination (Day 0-6) * Occurrence, intensity and relationship to vaccination of unsolicited AEs during the 28-day follow-up period post each vaccination (Day 0-27) * Hematological and biochemical levels at study visits on Days 0, 7, 28, 35 and 56 * Occurrence of serious adverse events (SAEs) from Day 0 to Day 56 * Occurrence of potential immune-mediated diseases (pIMDs) and medically attended AEs from Day 0 to Day 56

    Up to Day 56

  • Humoral immunogenicity to each of four DENV types of various TDENV-PIV formulations 28 days after the second dose (Day 56)

    Humoral Immunogenicity: Neutralizing antibody titers specific to each DENV type at Day 56 * Geometric mean titers (GMTs) of neutralizing antibody titers to each DENV type * Rate of fold increases in neutralizing antibody from Day 0 for each DENV type * Seropositivity rates for each DENV type * Trivalent and tetravalent seropositivity rates

    Day 56

Secondary Outcomes (3)

  • Safety of various TDENV-PIV formulations, from Day 0 to Month 13 (Visits 1-11)

    Up to month 13

  • Humoral immunogenicity to each of four DENV types of various TDENV-PIV formulations on Days 0, 7 and 28 and Months 7 and 13

    Up to month 13

  • • To evaluate the safety of various TDENV-PIV formulations from Month 14 through the end of the study (Visit 15)

    Up to the end of study (Month 37-39)

  • History of, or current auto-immune disease
  • History of any reaction or hypersensitivity likely to be exacerbated by any component of the vaccine/placebo or related to a study procedure
