Multivalent HPV (Human Papillomavirus) Vaccine Study in 16- to 26-Year Old Men and Women (V503-003)

Phase 3
Completed
Conditions
Genital Warts
Anal Cancer
Anal Intraepithelial Neoplasia
Interventions
Biological: 9vHPV Vaccine
Registration Number
NCT01651949
Lead Sponsor
Merck Sharp & Dohme LLC
Brief Summary

This study is designed to evaluate the immunogenicity and tolerability of 9vHPV (9-valent HPV vaccine, V503) in 16- to 26-year old men and women. The overall goal is to bridge 9vHPV efficacy findings in young women to young men based on the demonstration of similar immunogenicity and safety profiles. The primary hypothesis is that 9vHPV induces antibody responses at 4 weeks postdose 3 in heterosexual males that are non-inferior to antibody responses in young women.

Detailed Description

Study participants will be administered a 3-dose regimen of 9vHPV. They will be assessed for immunogenicity 1 month following completion of vaccination. All participants will be followed for safety for a total of 12 months.

Primary Outcome Measures
NameTimeMethod
Geometric Mean Titers (GMTs) to the HPV Types Contained in the 9vHPV VaccineFour weeks post vaccination 3 (Month 7)

Serum antibodies to HPV types 6/11/16/18/31/33/45/52/58 were measured with a Competitive Luminex Immunoassay. Titers are reported in milli Merck Units/mL

Percentage of Participants With Elevated Oral Body Temperature (>=37.8° C, >=100° F)Up to 5 days after any vaccination

Participants were instructed by the investigator to use the Vaccination Report Card to document evening oral temperature daily after each study vaccination

Percentage of Participants With One or More Injection-site Adverse Experiences Prompted on the Vaccination Report CardUp to 5 days after any vaccination

An adverse experience (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 study vaccine, whether or not considered related to the use of the product. Any worsening of a preexisting condition which is temporally associated with the use of the study vaccine is also an AE. Injection-site AEs prompted on the Vaccination Report Card (VRC) were erythema, pain, and swelling. Participants were instructed to use the Vaccination Report Card to record AEs daily after each study vaccination.

Percentage of Participants With an Adverse EventUp to Month 12

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 study vaccine, whether or not considered related to the use of the product. Any worsening of a preexisting condition which is temporally associated with the use of the study vaccine is also an AE.

Percentage of Participants Who Had Study Vaccine Discontinued Due to an Adverse EventUp to Month 12

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 study vaccine, whether or not considered related to the use of the product. Any worsening of a preexisting condition which is temporally associated with the use of the study vaccine is also an AE.

Secondary Outcome Measures
NameTimeMethod
Percentage of Participants With Seroconversion to the HPV Types Contained in the 9vHPV VaccineFour weeks post vaccination 3 (Month 7)

Serum antibodies to HPV types were measured with a Competitive Luminex Immunoassay. The serostatus cutoffs (milli Merck U/mL) for HPV types were as follows: HPV Type 6: ≥30; HPV Type 11: ≥16; HPV Type 16: ≥20; HPV Type 18: ≥24; HPV Type 31: ≥10; HPV Types 33, 45, 52, and 58: ≥8.
