NCT00717834

Brief Summary

The primary objective of this study is to assess the safety and tolerability of the Ross River Virus (RRV) Vaccine in a healthy young adult population. Other objectives of this study are to assess the immunogenicity of the RRV Vaccine in a healthy young adult population and to identify the optimal dose level of the RRV Vaccine in a healthy young adult population.

Outcome Measures

Primary Outcomes (2)

  • Rates of subjects with fever with onset within 7 days after the first and 7 days after the second vaccination

    Within 7 days after the first and second vaccinations

  • Immune response measured by RRV-specific IgG titer 21 days after the second vaccination

    21 days after the second vaccination

Study Arms (8)

Cohort 1, Treatment Arm 1

EXPERIMENTAL

Randomization of a total of approx. 200 subjects to one of four treatment arms at 1:1:1:1 ratio to receive 1.25 µg of the RRV Vaccine with/without adjuvant (Al(OH)3), or 2.5 µg of the RRV Vaccine with/without adjuvant (Al(OH)3). Cohort 1 is subdivided into Cohort 1a (n = 60, i.e. 15 subjects per dose/adjuvantation combination) to receive the first vaccination on Day 0, with Day 7 safety data being reviewed by a Data Monitoring Committee and, following DMC recommendation, to receive the second vaccination at Day 21; Cohort 1b (n=140, i.e. 35 subjects per dose/adjuvantation combination) is to be vaccinated twice 21 days apart upon availability of DMC recommendation. Booster vaccination to follow 180 days after first vaccination.

Biological: Formalin-treated, UV-inactivated, whole-virion, Vero cell-derived, preservative free Ross River Virus (RRV) vaccine with or without an Al(OH)3 adjuvant

Cohort 2, Treatment Arm 1

EXPERIMENTAL

Randomization of a total of approx. 100 subjects to one of two treatment arms at 1:1 ratio to receive 5 µg of the RRV Vaccine with/without adjuvant (Al(OH)3). Vaccinations take place upon review of Cohort 1a Day 7 safety data by DMC and recommendation to proceed. Booster vaccination to follow 180 days after first vaccination.
