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

Brief Summary
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.

Outcome Measures
Primary Outcomes (6)
Percentage of Participants With Seroconversion for HPV Types 6, 11, 16, and 18
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.
Four weeks postdose 3 (Month 7)
Percentage of Participants With Elevated Oral Temperature (>=37.5° C)
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.
Up to Day 5 after any vaccination
Percentage of Participants With an Injection-site Adverse Event
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.
Up to Day 5 after any vaccination
Percentage of Participants With a Systemic Adverse Event
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 VRC-prompted systemic AEs that occurred in the 5 days after any vaccination. The percentage of participants with a systemic AE was summarized.
Up to Day 15 after any vaccination
Percentage of Participants With a Serious Adverse Event
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.
Up to Day 15 after any vaccination
Percentage of Participants With a Vaccine-related Serious Adverse Event
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 that were considered at least possibly related to the study vaccine was summarized.
