Infection with human papillomavirus (HPV) has been clearly established as the central cause of cervical cancer. Indeed, certain oncogenic types of HPV can infect the cervix (part of the uterus or womb). This infection may go away by itself, but if it does not go away (this is called persistent infection), it can lead in women over a long period of time to cancer of the cervix. This study will evaluate the immunogenicity and safety of GSK Biologicals HPV-16/18 vaccine over 12 months, in women up to 55 years of age at study start. Approximately 660 study subjects will receive the HPV vaccine administered intramuscularly according to a 0-1-6 month schedule. The study will be extended to assess long-term safety and immunogenicity of the HPV-16/18 vaccine.

Number of Seroconverted Subjects for Anti-human Papilloma Virus 16 (Anti-HPV-16) and Anti-human Papilloma Virus 18 (Anti-HPV-18) Antibodies, in Women 15 to 25 Years of Age and Women 26 to 45 Years of Age
Seroconversion was defined as the appearance of anti-HPV-16 and/or anti-HPV-18 antibodies \[i.e. antibody titer greater than or equal to (≥) the cut-off value\] in the sera of subjects seronegative before vaccination. Cut-off values were 8 enzyme-linked immunosorbent assay (ELISA) units per milliliter (EL.U/mL) for anti-HPV-16 antibodies and 7 EL.U/mL for anti-HPV-18 antibodies. Data for the Cervarix (46-55 Years) Group are presented in the Secondary Outcomes as per Protocol.
Time frame: At Month 7
Anti-HPV-16/18 Antibody Titers Assessed by ELISA Based on the ATP Cohort for Immunogenicity at Months 18, 24, 36 and 48
Anti-HPV 16/18 antibody titers were detected in sera samples and presented as Geometric Mean Titers (GMT), expressed in EL.U/mL. Data for pre-vaccination, Month 2, Month 7 and Month 12 are presented in the Secondary Outcomes as per Protocol.
Time frame: At Months 18, 24, 36 and 48
Number of Seroconverted Subjects for Anti-HPV-16 and Anti-HPV-18 Antibodies, in Women 46 - 55 Years of Age
Seroconversion was defined as the appearance of anti-HPV-16 and/or anti-HPV-18 antibodies (i.e. antibody titer ≥ cut-off value) in the sera of subjects seronegative before vaccination. Cut-off values were 8 EL.U/mL for anti-HPV-16 antibodies and 7 EL.U/mL for anti-HPV-18 antibodies. Seroconversion results at Month 7 for the Cervarix (15-25 Years) Group and for the Cervarix (26-45 Years) Group are presented in the Primary Outcome Measure 1.
Time frame: At Month 7
Anti-HPV-16/18 Antibody Titers Assessed by ELISA Based on the ATP Cohort for Immunogenicity at Pre-vaccination (PRE) and Months 2, 7 and 12
Anti-HPV 16/18 antibody titers were detected in sera samples and presented as GMT, expressed in EL.U/mL. Data for Months 18, 24, 36 and 48 are presented in the Primary Outcome Measure 2 as per Protocol.
Time frame: At PRE and Months 2, 7 and 12
Number of Subjects Seroconverted for Anti-HPV-16 and Anti-HPV-18 Antibodies at Month 2 and Month 12
Seroconversion was defined as the appearance of anti-HPV-16 and/or anti- HPV-18 antibodies (i.e. antibody titer ≥ cut-off value) in the sera of subjects seronegative before vaccination. Cut-off values were 8 EL.U/mL for anti-HPV-16 antibodies and 7 EL.U/mL for anti-HPV-18 antibodies. Seroconversion results at Month 7 are presented in the Primary Outcome Measure 1 for Cervarix (15-25 Years) Group and Cervarix (26-45 Years) Group and in the Secondary Outcome Measure 3 for the Cervarix (46-55 Years) Group.
Time frame: At Month 2 and Month 12
Number of Subjects With Any, Grade 3 and Related Solicited General Symptoms
Assessed solicited general symptoms were arthralgia, fatigue, fever, gastrointestinal symptoms, headache, myalgia, rash and urticaria. Any = occurrence of the symptom regardless of intensity grade. Grade 3 symptom = symptom that prevented normal activity. Grade 3 fever = fever above (\>) 39.0 °C. Related = symptom assessed by the investigator as related to the vaccination.
Time frame: During the 7-day period (from the day of vaccination up to 6 subsequent days) following vaccination after each dose and across doses
Number of Subjects With Any and Grade 3 Solicited Local Symptoms
Assessed solicited local symptoms were pain, redness and swelling. Any = occurrence of the symptom regardless of intensity grade. Grade 3 pain = pain that prevented normal activity. Grade 3 redness/swelling = redness/swelling spreading beyond 50 millimetres (mm) of injection site.
Time frame: During the 7-day period (from the day of vaccination up to 6 subsequent days) following vaccination after each dose and across doses
Number of Subjects With Any, Grade 3 and Related Unsolicited Adverse Events (AEs)
An unsolicited AE covers any untoward medical occurrence in a clinical investigation subject temporally associated with the use of a medicinal product, whether or not considered related to the medicinal product and reported in addition to those solicited during the clinical study and any solicited symptom with onset outside the specified period of follow-up for solicited symptoms. Any was defined as the occurrence of any unsolicited AE regardless of intensity grade or relation to vaccination. Grade 3 AE = an AE which prevented normal, everyday activities. Related = AE assessed by the investigator as related to the vaccination.
Time frame: During the 30-day (from the day of vaccination up to 29 subsequent days) post-vaccination period
Number of Subjects Reporting Serious Adverse Events (SAE)
An SAE is any untoward medical occurrence that resulted in death, was life-threatening, required hospitalization or prolongation of existing hospitalization, resulted in disability/incapacity, was a congenital anomaly/birth defect in the offspring of a study subject, or may have evolved into one of the outcomes listed above.
