V503 (9-valent HPV \[Types 6, 11, 16, 18, 31, 33, 45, 52, and 58\] L1 virus-like particle vaccine), 0.5 mL injection in 3 dose regimen (and a fourth injection for Cohort 1 only).

Experimental: V503

The purpose of this study was to evaluate the safety, efficacy, and immunogenicity of V503 in comparison to GARDASIL. The primary hypotheses tested in the study were 1) V503 administered to 16- to 26-year-old adolescents and young women is generally well-tolerated, 2) V503 reduces combined incidence of Human Papillomavirus (HPV) Type 31/33/45/52/58-related disease compared with GARDASIL, and 3) V503 induces non-inferior geometric mean titers for HPV Type 6/11/16/18 antibodies compared with GARDASIL.

The study included a dose-finding evaluation of a 3-dose regimen of V503 and GARDASIL, a safety/efficacy evaluation of a 3-dose regimen of the selected V503 dose formulation and GARDASIL, and an extension consisting of 2 substudies: an evaluation of immune memory in participants receiving a fourth vaccination with V503 (Cohort 1), and an opportunity for participants who received GARDASIL in the Base Study to receive a 3-dose regimen of V503 (Cohort 2).

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. This outcome measure applied to Cohort 1 participants only.

HPV Type 31/33/45/52/58-related high-grade Cervical Intraepithelial Neoplasia (CIN 2/3), Adenocarcinoma in Situ (AIS), Invasive Cervical Carcinoma, high-grade Vulvar Intraepithelial Neoplasia (VIN 2/3), high-grade Vaginal Intraepithelial Neoplasia (VaIN 2/3), vulvar cancer, or vaginal cancer were determined by clinical/pathologic criteria and positive Polymerase Chain Reaction (PCR) assay for virus subtype. This outcome measure reports data based on the protocol-specified plan of conducting hypothesis testing when at least 30 cases had accumulated. The cutoff date for this analysis was 10 April 2013. Disease incidence was defined as the number of primary efficacy cases per 10,000 person-years of follow-up in a treatment arm.

HPV Type 31/33/45/52/58-related high-grade Cervical Intraepithelial Neoplasia (CIN 2/3), Adenocarcinoma in Situ (AIS), Invasive Cervical Carcinoma, high-grade Vulvar Intraepithelial Neoplasia (VIN 2/3), high-grade Vaginal Intraepithelial Neoplasia (VaIN 2/3), vulvar cancer, or vaginal cancer were determined by clinical/pathologic criteria and positive Polymerase Chain Reaction (PCR) assay for virus subtype. This outcome measure reports cumulative study data through 10 March 2014. Disease incidence was defined as the number of primary efficacy cases per 10,000 person-years of follow-up in a treatment arm.

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. Statistical analysis was performed only for HPV types contained in both vaccines.

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.

Any worsening of a preexisting condition which is temporally associated with the use of the study vaccine is also an AE. AEs such as redness, swelling, and pain/tenderness/soreness at the injection site were recorded.

Any worsening of a preexisting condition which is temporally associated with the use of the study vaccine is also an AE. Systemic AEs were those not categorized as injection-site AEs.

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. An AE that is judged by the investigator to be "definitely related," "probably related," or "possibly related" to the study drug is defined as a vaccine-related AE.

An adverse event 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 adverse event.

Combined Incidence of HPV Type 31/33/45/52/58-related persistent infection as determined by clinical/pathologic criteria and positive Polymerase Chain Reaction (PCR) assay for virus subtype. Persistent infection was defined as infection detected in samples from \>=2 consecutive visits 6 months (+/-1 month visit window) or longer apart. Incidence was defined as the number of cases of persistent infection per 10,000 person-years of follow-up in a treatment arm.

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.

The analysis population included all participants who received \>=1 vaccination and had safety follow-up. Non-serious AEs were not solicited in Extension Cohort 2; however, some non-serious AEs were voluntarily reported.
