Stage I: Combined Incidence of HPV 6-, 11-, 16-, 18-, 31-, 33-, 45-, 52-, and 58-related External Genital and Intra-anal 12-month Persistent Infection,Stages I and II: Combined Incidence of HPV 6-, 11-, 16-, 18-, 31-, 33-, 45-, 52-, and 58-related Genital Warts, PIN, or Penile/Perianal/Perineal Cancer
This study will evaluate the efficacy, immunogenicity, and safety of 9-valent human
 papillomavirus (9vHPV; V503) vaccine in Chinese men 20 to 45 years of age. It will enroll
 heterosexual men (HM) and men who have sex with men (MSM), will be stratified by age and
 sexual orientation, and will have two stages. The primary hypothesis of Stage I is: 9vHPV
 vaccine reduces the combined incidence of HPV 6-, 11-, 16-, 18-, 31-, 33-, 45-, 52-, and
 58-related external genital and intra-anal 12-month persistent infection (PI) compared with
 placebo in males 20 to 45 years of age who are seronegative at Day 1 and polymerase chain
 reaction (PCR) negative from Day 1 through one month post-Dose 3 to the relevant HPV type.
 The primary hypothesis of Stages I and II combined is: 9vHPV vaccine reduces the combined
 incidence of HPV 6-, 11-, 16-, 18-, 31-, 33-, 45-, 52-, and 58-related genital warts,
 penile/perianal/perineal intraepithelial neoplasia (PIN), or penile/perianal/perineal cancer
 compared with placebo in males 20 to 45 years of age who are seronegative at Day 1 and PCR
 negative from Day 1 through one month post-Dose 3 to the relevant HPV type.
