- Brief Summary
Human Papillomavirus (HPV) infection has been established as a necessary cause of cervical cancer. GlaxoSmithKline (GSK) Biologicals has developed an HPV vaccine (580299) which targets the 2 most common oncogenic HPV types (HPV-16 and HPV-18), found in approximately 70% of all cervical cancers. In previous trials this vaccine has been found to be efficacious in the prevention of incident and persistent HPV-16/18 infections and associated cytological abnormalities and cervical dysplasia. In this partially-blind study, GSK Biologicals will evaluate the safety and immunogenicity of the HPV vaccine using an alternative schedule and an alternative dosing when administered in healthy young females aged 9 to 25 years, as compared to the standard HPV vaccine. The Protocol Posting has been updated in order to comply with the FDA Amendment Act, Sep 2007. The protocol posting has been updated following a protocol amendment.

The Cervarix vaccine was administered intramuscularly into the deltoid of the non-dominant arm.
- Primary Outcome Measures
Name Time Method Number of Subjects With Report of Any, and Grade 3 Solicited Local Symptoms Within 7 days (Day 0-6) after vaccination. Assessed solicited local symptoms were pain, redness and swelling. Any = occurrence of the solicited local symptom irrespective of intensity grade. Grade 3 pain = pain that prevented normal activity. Grade 3 redness/swelling = redness/swelling larger than (\>) 50 millimeters (mm).
Number of Subjects With Any, Grade 3 and Related Solicited General Symptoms Within 7 days (Day 0-6) after vaccination. Assessed solicited general symptoms were arthralgia, fatigue, fever (defined as axillary temperature equal or above (≥) 37.5 degrees Celsius (°C), gastrointestinal symptoms, which included nausea, vomiting, diarrhoea and/or abdominal pain, headache, myalgia, rash and urticaria. Grade 3 symptoms = symptoms that prevented normal activity. Grade 3 fever = axillary temperature ≥ 39 °C. Grade 3 urticaria = urticaria distributed on at least 4 body areas. Related symptom = symptom assessed by the investigator to be causally related to vaccination.
Titers of Anti-Papillomavirus 16 (Anti-HPV-16) and Anti-human Papillomavirus 18 (Anti-HPV-18) Antibodies One month after vaccination with the last dose of the Cervarix vaccine (Cervarix 1/Placebo Group: Month 3; Other groups: Month 7). Titers are given as Geometric Mean Titers (GMTs) expressed in Enzyme-linked immunosorbent assay (ELISA) units per milliliter (EL.U/mL).

Number of Subjects With Serious Adverse Events (SAEs). From Month 0 to Month 48. SAEs assessed include medical occurrences that result in death, are life threatening, require hospitalization or prolongation of hospitalization, result in disability/incapacity or are a congenital anomaly/birth defect in the offspring of a study subject.
Number of Subjects With Serious Adverse Events (SAEs) Throughout the study period, from Month 0 to Month 60. SAEs assessed include medical occurrences that result in death, are life threatening, require hospitalization or prolongation of hospitalization, result in disability/incapacity or are a congenital anomaly/birth defect in the offspring of a study subject.
Titers of Anti-Papillomavirus 16 (Anti-HPV-16) and Anti-human Papillomavirus 18 (Anti-HPV-18) Antibodies At Month 60 of the safety follow-up phase Titers are given as Geometric Mean Titers (GMTs) expressed in Enzyme-linked immunosorbent assay (ELISA) units per milliliter (EL.U/mL). The assay cut-off for Month 60 was defined as ≥ 19 ELISA units per milliliter (EL.U/mL).
Number of Subjects Reporting Clinically Relevant Abnormalities in Biochemical and Haematological Laboratory Parameters Assessed. At Month 7 (M7) Assessed parameters were alanine aminotransferase (ALT), basophils (BAS), creatinine (CREA), eosinophils (EOS), haematocritis (Hct), lymphocytes (LYM), monocytes (MON), neutrophils (NEU), platelets (PLA), red blood cells (RBC) and white blood cells (WBC). Subjects were categorized according to their results at pre-vaccination at Month 0 (PRE) which were normal, above normal or below the normal range. Per parameter and range, it was assessed whether laboratory values of the subjects were normal, above normal or below the normal range. This outcome presents PLA results.
Number of Seroconverted Subjects Against Human Papillomavirus 16 (HPV-16) and Human Papillomavirus 18 (HPV-18) At Month 60 of the safety follow-up phase Seroconversion was defined as the appearance of antibodies (i.e. titers greater than or equal to (≥) cut-off value) in the serum of subjects seronegative before vaccination. Assay cut-off was defined as ≥ 19 ELISA units per milliliter (EL.U/mL). Seronegative subjects are subjects who had an antibody concentration below cut-off value.

Pregnancy outcomes were ectopic pregnancy, elective termination with no apparent congenital anomaly (ACA), elective termination with congenital anomaly (CA), lost to follow up, pregnancy ongoing, spontaneous abortion with no ACA and live infant with no ACA.
Number of Subjects With Any, Grade 3 and Related Unsolicited Adverse Events (AEs). Within 30 days (Day 0-29) after vaccination. An unsolicited adverse event (AE) is any adverse event (i.e. any untoward medical occurrence in a patient or clinical investigation subject, temporally associated with use of a medicinal product, whether or not considered related to the medicinal product) 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.
