简要总结
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.

盲法说明
This study was performed in a double-blinded manner. Blinding was maintained for all subjects and investigators and their study staff participating in this study with regard to the individual subject treatment (vaccine treatment) assignments allocated in this study.
GSK personnel directly involved in the conduct of this study were also blinded to the subjects' treatment assignments.

结局指标
主要结局
Number of Seroconverted Subjects for Anti-Human Papillomavirus (Anti-HPV)-16 at Month 7
时间窗: 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
时间窗: 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
时间窗: 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
时间窗: At Month 7
Anti-HPV-18 antibody titers were presented as Geometric Mean Titers and expressed in EL.U/mL.
