Objectives
Primary Objective:
To demonstrate that a 3-dose
regimen of the 9vHPV vaccine will
reduce the incidence of HPV
16/18/31/33/45/52/58-related oral
persistent infection 6 months (± 1-month
window) or longer compared with
placebo in males 20 to 45 years of age
Secondary Objective:
To demonstrate that a 3-dose
regimen of the 9vHPV vaccine will
reduce the incidence of HPV 6/11-related
oral persistent infection 6 months
(± 1-month window) or longer compared
with placebo in males 20 to 45 years of
age

responses (GMT and seroconversion
percentages) to each of HPV 6, 11, 16,
18, 31, 33, 45, 52, and 58 at Month 7

tolerability of the 9vHPV vaccine when
administered to males 20 to 45 years of
age

Primary Outcome Measures :
Incidence of Human Papillomavirus (HPV)16/18/31/33/45/52/58-related 6-month Persistent Oral Infection [ Time Frame: Up to Month 42 ]
A 6-month persistent infection is defined to have occurred if a participant, after completion of the Month 7 visit, is positive for the same human papillomavirus (HPV) type by the HPV polymerase chain reaction (PCR) assay to at least 1 common gene in Oral Rinse and Gargle (ORG) samples obtained at 2 or more consecutive visits at 6 months (+/-1 month visit window) apart.
Secondary Outcome Measures :
Incidence of Human Papillomavirus (HPV) 6/11-related 6-month Persistent Oral Infection [ Time Frame: Up to Month 42 ]
A 6-month persistent infection is defined to have occurred if a participant, after completion of the Month 7 visit, is positive for the same human papillomavirus (HPV) type by the HPV polymerase chain reaction (PCR) assay to at least 1 common gene in Oral Rinse and Gargle (ORG) samples obtained at 2 or more consecutive visits at 6 months (+/-1 month visit window) apart.
Geometric Mean Titers to HPV Types 6, 11, 16, 18, 31, 33, 45, 52, and 58 Antibodies [ Time Frame: 1 month postdose 3 (Month 7) ]
Serum antibodies to HPV types are measured with competitive Luminex immunoassay (cLIA). Geometric mean titers of antibodies to HPV types will be calculated by exponentiating the mean estimates of natural logarithm of the anti-HPV titers.
Percentage of Participants who Seroconvert to Human Papillomavirus (HPV) Types 6, 11, 16, 18, 31, 33, 45, 52, and 58 [ Time Frame: 1 month postdose 3 (Month 7) ]
Seroconversion is defined as changing a participant's serostatus from seronegative at Day 1 to seropositive by 4 weeks postdose 3. A participant with anti-HPV competitive Luminex immunoassay (cLIA) titer at or above the serostatus cutoff of the cLIA for a given HPV type is considered seropositive for that HPV type.
Percentage of Participants with at Least 1 Solicited Injection-site Adverse Event (AE) [ Time Frame: Up to 5 days after any vaccination ]
An adverse event (AE) is defined as any untoward medical occurrence in a participant which does not necessarily have a causal relationship with the study vaccine. An AE can therefore be any unfavourable and unintended sign, symptom, or disease temporally associated with the use of study vaccine or a protocol-specified procedure, whether or not considered related to the study vaccine or protocol-specified procedure. Any worsening of a preexisting condition that is temporally associated with the study vaccine or protocol-specified procedure is also an AE. Solicited injection-site AEs such as redness/erythema, swelling, and tenderness/pain at the injection site will be recorded.
Percentage of Participants with Elevated Temperature (Fever) [ Time Frame: Up to 5 days after any vaccination ]
Participants are asked to record oral body temperatures. The percentage of participants with elevated temperature (≥37.8°C or 100.0°F) will be assessed.
Percentage of Participants Who Report at Least 1 Systemic Adverse Event [ Time Frame: Up to 15 days after any vaccination ]
An AE is defined as any untoward medical occurrence in a participant which does not necessarily have a causal relationship with the study vaccine. An AE can therefore be any unfavourable and unintended sign, symptom, or disease temporally associated with the use of study vaccine or a protocol-specified procedure, whether or not considered related to the study vaccine or protocol-specified procedure. Any worsening of a preexisting condition that is temporally associated with the study vaccine or protocol-specified procedure is also an AE. Systemic AEs are those not categorized as injection-site AEs.
Percentage of Participants Who Experience at Least 1 Serious Adverse Event (SAE) [ Time Frame: Up to 15 days after any vaccination ]
A serious adverse event (SAE) is defined as any untoward medical occurrence that, at any dose results in death, is life-threatening, requires inpatient hospitalization or prolongation of existing hospitalization, results in persistent or significant disability or incapacity, is a congenital anomaly/birth defect, or is another important medical event deemed such by medical or scientific judgment.
Percentage of Participants who Experience at Least 1 Serious Vaccine-Related Adverse Event [ Time Frame: Up to Month 42 ]
A SAE is defined as any untoward medical occurrence that, at any dose results in death, is life-threatening, requires inpatient hospitalization or prolongation of existing hospitalization, results in persistent or significant disability or incapacity, is a congenital anomaly/birth defect, or is another important medical event deemed such by medical or scientific judgment. An SAE that is considered by an investigator (a qualified physician) to be vaccine-related will be reported during entire study period.
Incidence of Human Papillomavirus (HPV)16/18/31/33/45/52/58-related 6-month Persistent Oral Infection [ Time Frame: Up to Month 42 ]
