Efficacy, Immunogenicity, and Safety of V503 in Chinese Males (V503-052)
Sponsor: Merck Sharp & Dohme LLC
Summary
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.
