Study Summary
The purpose of this study is to evaluate the efficacy, immunogenicity and safety of the 9vHPV vaccine in men 20 to 45 years of age. The primary hypothesis tested after the primary database lock is that administration of a 3-dose regimen of 9vHPV vaccine will reduce the incidence of human papillomavirus (HPV) 16/18/31/33/45/52/58-related oral persistent infection (6 months or longer) compared with placebo. There will also be an Extension Study to offer an opportunity to complete the 3 dose regimen of 9vHPV vaccine for participants who received placebo in the Base Study, or received less than 3 doses of 9vHPV vaccine in the Base Study.
Primary Outcome
A 6-month persistent infection is defined to have occurred if a participant, after completion of the Month 7 visit, is positive for the same HPV type by the HPV polymerase chain reaction (PCR) assay to at least 1 common gene in Oral Rinse and Gargle (ORG) samples obtained at 2 or more consecutive visits at 6 months (+/-1 month visit window) apart.
