Clinical Trial Summary

A Phase I, randomised, single centre, double-blind, placebo-controlled, parallel group study to evaluate the safety, tolerability and immunogenicity of two doses of Group B Streptococcus vaccine.


Description:

There will be 4 arms in 2 cohorts of 30 subjects. Cohort 1 will receive two 0.5 mL injections, 4 weeks apart, each consisting of 25 μg of GBS-NN and 25 μg of GBS-NN2 (24 subjects) or placebo (6 subjects). Cohort 2 (30 subjects) will receive two 0.5 mL injections, 4 weeks apart, each consisting of 50 μg of GBS-NN and 50 μg of GBS-NN2 (24 subjects) or placebo (6 Subjects). All vaccines will be adsorbed to 500 μg Al3+ as Alhydrogel®. Safety will be assessed after all subjects have completed Visit 4 (Day 8) for Cohort 1, at which point the decision will be made as to whether proceeding with administration of the doses in cohort 2 is appropriate.
