A study to evaluate the efficacy and tolerability of V501 (quadrivalent Human Papilloma Virus \[HPV\] \[Type 6, 11, 16 and 18\] L1 Virus-Like Particle vaccine, GARDASIL™) in healthy, 16- to 26-year old Japanese males. The hypotheses tested are: 1) V501 reduces the combined incidence of HPV 6-, 11-, 16-, or 18-related persistent infection compared with placebo, and 2) V501 reduces the combined incidence of HPV 6-, 11-, 16-, or 18-related persistent infection, condyloma acuminata, penile/perianal/perineal intraepithelial neoplasia, or penile, perianal, or perineal cancer compared with placebo.

Efficacy and Tolerability Study of V501 in Japanese Males (V501-122)

A Phase III Placebo-controlled Clinical Trial to Study the Tolerability, Immunogenicity and Efficacy of V501 in 16- to 26-year-old Japanese Men

Persistent infection was defined as 1) polymerase chain reaction (PCR) positive to HPV Type 6, 11, 16, or 18 in 2 consecutive anogenital or biopsy samples collected ≥4 months apart, or 2) Pathology Panel consensus diagnosis of condyloma acuminate, penile/perianal/perineal intraepithelial neoplasia (PIN), penile, perianal, or perineal cancer and PCR detection of HPV Type 6, 11, 16, or 18 in an adjacent section and PCR positive for the same HPV type at a separate adjacent visit. The combined incidence of HPV Type 6, 11, 16, or 18 persistent infection detected in samples from ≥2 consecutive visits ≥6 months apart was assessed.

Body temperature (oral or oral equivalent) was recorded on the Vaccination Report Card (VRC). The percentage of participants with a maximum temperature ≥37.5°C was summarized.

An adverse event (AE) is defined as any untoward medical occurrence in a participant which does not necessarily have a causal relationship with study drug. An AE can therefore be any unfavourable and unintended sign, symptom, or disease temporally associated with the use of study drug or a protocol-specified procedure, whether or not considered related to the study drug or protocol-specified procedure. Any worsening of a preexisting condition that is temporally associated with the study drug or protocol-specified procedure is also an AE. The percentage of participants with an injection-site AE prompted on the VRC (erythema, pain, and swelling) was summarized.

Quadrivalent HPV \[Type 6, 11, 16 and 18\] L1 VLP vaccine), 0.5 mL intramuscular injection on Day 1, Month 2, and Month 6

This is a study of V501 \[quadrivalent Human Papillomavirus (HPV) (Type 6, 11, 16 and 18) L1 virus-like particle (VLP) vaccine\] in healthy Japanese boys. This study will consist of two periods. Period I of the study is to evaluate the immunogenicity and tolerability of V501 up to Month 7. Period II of the study is to evaluate the long-term immunogenicity and safety from Month 7 to Month 30. Two analyses are planned. The first analysis will be conducted when all subjects have completed their Month 7 visit or have been discontinued before that time. The second analysis will be conducted at the end of study. The primary hypothesis tested in this study is that seroconversion rates for the vaccine HPV types will be \>90% at 4 weeks postdose 3.

Safety and Tolerability Study of V501 in Japanese Boys (V501-200)

A Phase III, Open-Label, Clinical Trial to Study the Safety and Immunogenicity of the Quadrivalent HPV (Types 6, 11, 16, 18) L1 VLP Particle (VLP) Vaccine in 9- to 15-Year-Old Japanese Boys

Antibodies to HPV Types 6, 11, 16, and 18 were measured using a competitive luminex immunoassay 4 weeks after 3rd vaccination (Month 7). Antibody titers were expressed as milli Merck units/mL (mMU/mL). Seroconversion was defined as an anti-HPV 6 titer ≥20 mMU/mL, an anti-HPV 11 titer ≥16 mMU/mL, an anti-HPV 16 titer of ≥20 mMU/mL and an anti-HPV 18 titer of ≥24 mMU/mL.

The parent/guardian of the participant was to record the participant's oral temperature in the evening after each study vaccination and daily for 4 days after each study vaccination. Elevated temperature was defined as ≥99.5°F (≥37.5ºC). The percentage of participants that had an elevated temperature was summarized.

An adverse event (AE) is defined as any untoward medical occurrence in a participant which does not necessarily have a causal relationship with study drug. An AE can therefore be any unfavourable and unintended sign, symptom, or disease temporally associated with the use of study drug or a protocol-specified procedure, whether or not considered related to the study drug or protocol-specified procedure. Any worsening of a preexisting condition that is temporally associated with the study drug or protocol-specified procedure is also an AE. The parent/guardian of the participant was to record the presence of any vaccination report card (VRC)-prompted injection-site AEs that occurred in the 5 days after any vaccination. The percentage of participants with an injection-site AE prompted on the VRC (erythema, pain, and swelling) was summarized.

An AE is defined as any unfavorable and unintended change in the structure, function, or chemistry of the body temporally associated with the use of the sponsor's product, whether or not considered related to the use of the product. A serious adverse event (SAE) is an AE that results in death, is life threatening, results in a persistent or significant disability or incapacity, results in or prolongs an existing hospitalization, is a congenital anomaly or birth defect, is a cancer, is an overdose, or is another important medical event. The percentage of participants that experienced 1 or more SAEs was summarized.

Antibodies to HPV Types 6, 11, 16, and 18 were measured using a competitive luminex immunoassay. Antibody titers were expressed mMU/mL. GMTs obtained for each anti-HPV from this study were compared to each of the ant-HPV GMTs obtained in study V501-122 (NCT NCT01862874) in which Japanese males 16 to 26 years received V501 in the same 3 dose regimen, to test a hypothesis that would demonstrate non-inferiority.

Antibodies to HPV Types 6, 11, 16, and 18 were measured using a competitive luminex immunoassay. Antibody titers were expressed as mMU/mL.

Serum antibodies to HPV types were measured with a competitive luminex immunoassay. The serostatus cutoffs (mMU/mL) for HPV types were as follows: HPV Type 6: ≥20; HPV Type 11: ≥16; HPV Type 16: ≥20; HPV Type 18: ≥24

Serum antibodies to HPV types were measured with a competitive luminex immunoassay. The serostatus cutoffs (mMU/mL) for HPV types were as follows: HPV Type 6: ≥20; HPV Type 11: ≥16; HPV Type 16: ≥20; HPV Type 18: ≥24.

The thirty-six-month immunogenicity evaluation of Quadrivalent HPV (Types 6, 11, 16, 18) L1 Virus-Like Particle (VLP) Vaccine in Chinese female subjects aged 9 to 45 years and male subjects aged 9 to 15 years.

All eligible subjects will be enrolled for one visit. A medical history and physical examination will be conducted on all subjects. A 10 mL blood specimen will be collected. All Sera should be shipped to PPD Vaccines and Biologics Laboratory in the US. The serum specimen will be tested at PPD Laboratory with competitive Luminex immunoassay (cLIA) and multiplexed HPV immunoassay. The purpose of the quadrivalent HPV cLIA and multiplex is to detect neutralizing antibody and total IgG to HPV virus-like particles (VLPs), serotypes 6, 11, 16, 18, respectively.
