Overview

Brief Summary

Human Papilloma viruses (HPV) are viruses that cause infections of the skin and genitals in men and women. Several types of HPV infection are transmitted by sexual activity and, in women, can infect the cervix (part of the uterus or womb). This infection, if it persists, can lead over a long period of time to cancer of the cervix in women. In collaboration with MedImmune Inc., GlaxoSmithKline Biologicals has developed a HPV vaccine against the oncogenic types HPV-16 and HPV-18 formulated with the adjuvant AS04. GSK Biologicals is also evaluating novel HPV vaccine formulations.This study will evaluate the immunogenicity and safety of a novel GSK Biologicals HPV vaccine in women 18-25 years of age at study start. Approximately 376 study subjects will receive the novel HPV vaccine or the control vaccine administered intramuscularly according to a 0-1-6 month schedule.

  • Subject must be free of obvious health problems
  • Subject must be of non-childbearing potential and have had no more than 6 lifetime sexual partners

Exclusion Criteria

Outcomes

Primary Outcomes

Number of Seroconverted Subjects for Anti-Human Papillomavirus (Anti-HPV)-16 at Month 7

Time Frame: At Month 7

Seroconversion was defined as the appearance of anti-HPV-16 antibodies \[i.e. antibody titer greater than or equal to (≥) the cut-off value\] in the serum of subjects seronegative before vaccination. The cut-off value was 8 enzyme-linked immunosorbent assay (ELISA) units per milliliter (EL.U/mL).

Number of Seroconverted Subjects for Anti-HPV-18 at Month 7

Time Frame: At Month 7

Seroconversion was defined as the appearance of anti-HPV-18 antibodies (i.e. antibody titer ≥ cut-off value) in the serum of subjects seronegative before vaccination. The cut-off value was 7 EL.U/mL.

Anti-HPV-16 Antibody Titers Assessed by ELISA at Month 7

Time Frame: At Month 7

Anti-HPV-16 antibody titers were presented as Geometric Mean Titers (GMT) and expressed in EL.U/mL.

Anti-HPV-18 Antibody Titers Assessed by ELISA at Month 7

Time Frame: At Month 7

Anti-HPV-18 antibody titers were presented as Geometric Mean Titers and expressed in EL.U/mL.

  • Number of Subjects With Any Serious Adverse Events (SAEs)(From Day 0 to Month 7)
  • Number of Subjects With Any SAEs During the Extended Safety Follow-up(From Day 0 to Month 12)
  • Number of Subjects Reporting Pregnancies and Outcomes of Reported Pregnancies(From Day 0 to Month 12)
  • Number of Subjects Reporting New Onset of Chronic Diseases (NOCDs)(From Day 0 up to Month 12)
  • Number of Subjects Reporting Medically Significant Conditions(From Day 0 up to Month 12)
