Combined Phase II/Phase III Efficacy Studies of
GARDASIL
  • 20,541 women (1626 years of age) from the
    Americas, Europe, and Asia were enrolled in one
    of four trials.1
  • In one trial, subjects were randomized to either
    a monovalent HPV 16 L1 virus-like particle (VLP)
    vaccine or placebo. In three trials, subjects
    were randomized to either quadrivalent HPV (types
    6, 11, 16, 18) L1 VLP vaccine or placebo.1
  • Vaccine or placebo was administered at day 1 and
    months 2 and 6.1
  • ThinPrep Pap smears and swabs for HPV DNA were
    taken at day 1, month 7, month 12 and in 6- to
    12-month intervals thereafter until month 48.23
  • All Pap tests and biopsies processed/read at a
    central laboratory.3
  • Expert pathology panel read all slides for
    end-point determination.3

GARDASIL Phase III Adolescent Immunogenicity
Substudy Study Rationale and Objective
  • Rationale1
  • Prophylactic HPV vaccines are most effective when
    given before population enters risk period for
    acquisition of infection.1
  • Peak prevalence of HPV occurs among women during
    their teens and in their 20s.2
  • Young adolescents represent an ideal population
    for HPV vaccination.1
  • Objective
  • Determine whether HPV L1 VLP vaccine-induced
    anti-HPV neutralizing antibody responses in 10-
    to 15-year-old girls and boys are comparable to
    responses in 16- to 23-year-old females.3

  • In both boys and girls, GMTs at month 18 were
    approximately 4- to 7-fold lower than the GMTs
    observed at month 7.

GARDASIL Demonstrated Immune Memory
Vaccination series for GARDASIL V Vaccination at
day 0, month 2, and month 6
Antigen challenge A Antigen challenge at month 60
When tested by antigen challenge, vaccinated
subjects demonstrated classic immune memorythe
hallmark of long-term protection.1
Antibody levels stabilized through at least five
years and counting.1
Antibodies were built up during the
3-dose vaccination series.
Minimum protective level of antibodies is defined
through breakthrough cases. Through five years,
there were no breakthrough cases for GARDASIL,
while there were continuing infections for
placebo.

GARDASIL Durable Protection Through Five Years
PPE population subjects were naïve to HPV types
6, 11, 16, and/or 18
A total of 241 subjects were entered into the
five-year extension phase of protocol 007. One
case of confirmed persistent infection HPV 18
DNA detected at months 12 and 18 only (not a case
in the five-year extension). One case of HPV 16
DNA detected at the last visit (month 36) not a
subject in the five-year extension
phase. GARDASIL is a trademark of Merck Co.,

Nordic Cancer Registry Extension Long-Term
Efficacy of Vaccination
  • Nordic European countries have organized
    mass-screening programs.
  • Compulsory reporting of Paps, biopsies,
    CIN/cancer
  • Registries are sources for prospective studies
  • Through these registries, we can evaluate
  • Duration of effectiveness
  • Interaction of vaccination with cervical
    screening programs
  • Long-term safety
