Effectiveness, Safety and Immunogenicity of GSK Biologicals' HPV Vaccine GSK580299 (Cervarix) Administered in Healthy Adolescents

Genital infections with oncogenic human papillomaviruses (HPV) are common in both men and women. The most important disease associated with oncogenic HPV infection is cervical cancer, currently the second leading cause of cancer-related death among women globally. The current study is designed to evaluate the overall impact of HPV immunization in adolescents 12-15 years of age.

Who can participate

Healthy volunteers accepted: Yes

Only the study team can determine whether someone qualifies for participation.

Inclusion criteria

  • Study participants who the investigator or delegate believes that they and/or their parents/legally acceptable representative can and will comply with the requirements of the protocol (e.g. completion of the diary cards, return for follow-up visits) should be enrolled in the study.
  • A male or female between, and including, 12 and 15 years of age at the time of the first vaccination.

A written informed assent must be obtained from all study participants prior to enrolment. In addition, a written informed consent must be obtained from the study participants' parent or legally acceptable representative.

Note: As according to the Finnish law legal age of consent is 15 years, a written informed consent form can be obtained from study participants aged 15 years old and their parent(s)/legally acceptable representative(s) will receive a letter informing them of their child participation to the study.

  • Healthy male and female study participants as established by medical history before entering into the study. If needed, a history-directed clinical examination will be performed by the investigator or delegate (e.g. study nurse).
  • Study participants must not be pregnant. Absence of pregnancy should be verified (e.g. urine pregnancy test) as per investigator's or delegate's clinical judgement.
  • If the study participant is female, she must be of non-childbearing potential, i.e. be abstinent, have a current tubal ligation, hysterectomy, ovariectomy or be post-menopausal or pre-menarcheal, or if she is of childbearing potential, she must use adequate contraception for 30 days prior to vaccination and continue for 2 months after completion of the vaccination series.

Exclusion criteria

  • Previous vaccination against HPV or Hepatitis B virus.
  • History of allergic disease or reactions likely to be exacerbated by any component of the vaccines.
  • Acute disease at the time of enrolment. (Acute disease is defined as the presence of a moderate or severe illness with or without fever. All vaccines can be administered to persons with a minor illness such as diarrhoea, mild upper respiratory infection with or without low-grade febrile illness, i.e. Oral temperature <37.5°C (99.5°F) / Axillary temperature <37.5°C (99.5°F) / Rectal temperature <38°C (100.4°F).)
  • Pregnant or lactating female.

Primary outcomes

  1. Number of Female Subjects With Overall Vaccine Effectiveness Against Genital Infection With Human Papilloma Virus (HPV)-16/18 Types in Cervarix/Engerix-B B Group Versus Engerix-B Group and in Cervarix/Engerix-B A Group Versus Engerix-B Group

    Time frame: At the time of Visit 5 (i.e. at 18.5 years of age)

    The analysis of overall effectiveness of Cervarix vaccine against genital infection with HPV-16/18 types was based on stratified Mantel-Haenszel adjusted for clustering. The overall vaccine effectiveness was computed as 1- the prevalence odd ratio in all subjects from the investigated group (prevalence rate in all subjects from the investigated group/prevalence rate in all subjects from Engerix-B Group).

Secondary outcomes

  1. Number of Female Subjects With Overall Vaccine Effectiveness Against Genital Infection With HPV-16/18 Types in Cervarix/Engerix-B A Group Versus Cervarix/Engerix-B B Group

    Time frame: At the time of Visit 5 (i.e. at 18.5 years of age)

    The analysis of overall effectiveness of Cervarix vaccine against genital infection with HPV-16/18 types was based on stratified Mantel-Haenszel adjusted for clustering. The overall vaccine effectiveness was computed as 1- the prevalence odd ratio in all subjects from the investigated group (prevalence rate in all subjects from the Cervarix/Engerix-B A Group/prevalence rate in all subjects from Engerix-B Group).

    Note: As per Protocol and as the confirmatory objectives were not met, only exploratory interpretation could be performed for what concerns this secondary outcome measure.
