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 milliMerck units per milliliter (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.

Percentage of Participants with an Injection-site Adverse Event [3] | ||||||||
End point description |
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.

Antibodies to HPV Types 6, 11, 16, and 18 were measured using a competitive Luminex immunoassay. Antibody titers were expressed as milli Merck units/mL (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. Due to limitations in EudraCT data entry system, these comparisons cannot be included in the record. The comparisons can be viewed at https://clinicaltrials.gov/ (NCT02576054).
