Treatment and study plan

quadrivalent human papillomavirus (types 6, 11, 16, 18) recombinant vaccine

Biological

V501; Gardasil, 0.5 ml injection in 3 dosing regimen

Other names: V501, Gardasil

Comparator: Placebo

Biological

Placebo 0.5 ml injection in 3 dosing regimen

Primary outcomes

  1. Combined Incidence of Persistent Human Papillomavirus (HPV) 6, 11, 16 and 18 Infection or HPV 6, 11, 16 and 18 Related-Disease as Determined by Clinical/Pathologic Criteria and Positive Polymerase Chain Reaction (PCR) Assay for Virus Subtype

    Time frame: Over 30 months

    Participants with HPV 6, 11, 16 or 18 persistent infection, and genital disease (e.g., cervical, vaginal or vulval intraepithelial neoplasia, or cancer, adenocarcinoma in situ and genital warts) per 100 person-years of follow up.

Secondary outcomes

  1. Vaccine Type Serum Antibody Titer at One Month After Completed Vaccination Series (Anti-HPV 6)

    Time frame: At one month after completed vaccination series (Month 7)

    Month 7 HPV Competitive Luminex immunoassay (cLIA) Geometric Mean Titers (GMTs) by vaccine group.

    The limit of detection of the assay was 7 mMU/ml. GMTs and confidence limits below the limit of detection are shown as "7.0".

  2. Vaccine Type Serum Antibody Titer at One Month After Completed Vaccination Series (Anti-HPV 11)

    Time frame: At one month after completed vaccination series (Month 7)

    Month 7 HPV cLIA Geometric Mean Titers by vaccine group.

    The limit of detection of the assay was 8 mMU/ml. GMTs and confidence limits below the limit of detection are shown as "8.0".

  3. Vaccine Type Serum Antibody Titer at One Month After Completed Vaccination Series (Anti-HPV 16)

    Time frame: At one month after completed vaccination series (Month 7)

    Month 7 HPV cLIA Geometric Mean Titers by vaccine group.

    The limit of detection of the assay was 11 mMU/ml. GMTs and confidence limits below the limit of detection are shown as "11.0".

  4. Vaccine Type Serum Antibody Titer at One Month After Completed Vaccination Series (Anti-HPV 18)

    Time frame: At one month after completed vaccination series (Month 7)

    Month 7 HPV cLIA Geometric Mean Titers by vaccine group.

    The limit of detection of the assay was 10 mMU/ml. GMTs and confidence limits below the limit of detection are shown as "10.0".
