About this study

This is a Phase II, randomized, observer-blind, placebo-controlled, multi-site trial of the FDA licensed rMenB+OMV NZ vaccine, Bexsero. The targeted study population is men and women 18-50 years of age who are disproportionately vulnerable to N. gonorrhoeae infection. Approximately 2,200 participants are expected to be enrolled to achieve at least 202 primary endpoints in the Per Protocol Population. Data will be collected in an observer-blind manner. Study product recipients and study staff responsible for the evaluation of any study endpoint will be unaware of whether Bexsero or placebo were administered. The duration of the study for participants who are enrolled and randomized will be approximately 16 months. Study participation is expected to be completed in approximately 36 months. The primary objective of the study is to demonstrate efficacy of Bexsero in prevention of urogenital and/or anorectal gonococcal infection.
