Healthy subjects as established by medical history and history-directed clinical examination before entering into the study. Subjects must not be pregnant. Absence of pregnancy will be verified with a urine pregnancy test before each vaccination. Subjects must be either of non-childbearing potential, or if of childbearing potential, they must be abstinent or have practiced adequate contraception for 30 days prior to vaccination, have a negative pregnancy test and agree to continue such precautions for 2 months after completion of the vaccination series. Exclusion Criteria: Use of any investigational or non-registered product other than the study vaccines within 30 days preceding the first dose of study vaccine, or planned use during the study period. Chronic administration of immunosuppressants or other immune-modifying drugs within six months prior to the first vaccine dose. Planned administration/administration of a vaccine not foreseen by the study protocol within 30 days before and 30 days after (i.e., Days 0-29) the first dose of vaccine. Concurrently participating in another clinical study, at any time during the study period, in which the subject has been or will be exposed to an investigational or a non-investigational product. A subject planning to become pregnant, likely to become pregnant or planning to discontinue contraceptive precautions during the study period and up to two months after the last vaccine dose. Pregnant or breastfeeding. Subjects must be at least three months post-pregnancy and not breastfeeding to enter the study. Previous vaccination against HPV or planned administration of any HPV vaccine other than that foreseen by the protocol during the study period. Previous administration of components of the study vaccine. History of chronic condition(s) requiring treatment such as cancer or autoimmune disease. History of allergic disease, suspected allergy or reactions likely to be exacerbated by any component of the vaccine. Hypersensitivity to latex. Any confirmed or suspected immunosuppressive or immunodeficient condition, based on medical history and physical examination. Acute disease at the time of enrolment. Administration of immunoglobulins and/or any blood products within the three months preceding the first dose of study vaccine or planned administration during the study period.

Masking: Triple


Arms and Interventions

| Participant Group/Arm | Intervention/Treatment |
| --- | --- |
| Experimental: Cervarix Group<br>Subjects received 3 doses of Cervarix vaccine. Cervarix vaccine was administered intramuscularly into the deltoid muscle of the non-dominant arm according to a 0, 1, 6-month schedule. | Biological: CervarixTM<br>* Subjects will receive three doses of the Cervarix vaccine intramuscularly according to a 0, 1, 6-month schedule.<br>|
| Experimental: Placebo Group<br>Subjects received 3 doses of placebo. Placebo vaccine was administered intramuscularly into the deltoid muscle of the non-dominant arm according to a 0, 1, 6-month schedule. | Other: Control<br>* Subjects will receive three doses of control intramuscularly according to a 0, 1, 6-month schedule.<br>|

What is the study measuring?
-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Geometric Mean Titers (GMTs) for Antibodies Against Human Papillomavirus (HPV)-16/18 Antigens | Titers were given as geometric mean titers and were measured by Enzyme-linked Immunosorbent Assay (ELISA) and expressed as Enzyme-linked Immunosorbent Assay Units Per Milliliter (EL.U/mL). | One month after the third dose (at Month 7) | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Number of Subjects Seroconverted for Anti-HPV-16 and Anti-HPV-18 Antibodies | Seroconversion is 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 enzyme-linked immunosorbent assay units per milliliter (EL.U/mL) for anti-HPV-16 antibodies and 7 EL.U/mL for anti- HPV-18 antibodies. | At Month 7 | 
| Number of Subjects Reporting Any and Grade 3 Solicited Local Symptoms | Solicited local symptoms assessed were pain, redness and swelling. Any was defined as any solicited local symptom reported irrespective of intensity. Grade 3 pain was defined as pain that prevented normal activity. Grade 3 redness and swelling were defined as redness/swelling above 50 millimeter (mm). | During the 7 days (Days 0 - 6) following each vaccination | 
| Number of Subjects Reporting Any, Grade 3 and Related Solicited General Symptoms | Solicited general symptoms assessed were arthralgia, fatigue, gastrointestinal, headache, myalgia, rash, urticaria and fever (= axillary temperature above 37.0 degrees Celsius (°C). Grade 3 fever = axillary temperature above 39.0°C. Grade 3 urticaria = urticaria distributed on at least 4 body areas. For other symptoms, any = occurrence of any general symptom regardless of intensity grade or relation to vaccination and grade 3 = a general symptom that prevented normal activity. Related was a general symptom assessed by the investigator as causally related to the study vaccination. | During the 7 days (Days 0 - 6) following each vaccination | 
| Number of Subjects Reporting Medically Significant Conditions (MSCs) | Medically significant conditions (MSCs) are defined as: adverse events (AEs) prompting emergency room or physician visits that are not (1) related to common diseases or (2) routine visits for physical examination or vaccination, or serious adverse events (SAEs) that are not related to common diseases. Common diseases include: upper respiratory infections, sinusitis, pharyngitis, gastroenteritis, urinary tract infections, cervicovaginal yeast infections, menstrual cycle abnormalities and injury. MSCs were collected regardless of causal relationship to vaccination and intensity. | Throughout the study period (from Day 0 up to Month 12) | 
| Number of Subjects Reporting Pregnancies and Pregnancy Outcomes |  | Throughout the study period (from Day 0 up to Month 12) | 
| Number of Subjects Reporting Any, Grade 3 and Related Unsolicited Adverse Events (AEs) | Unsolicited AE covers any AE 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 occurrence of any unsolicited symptom regardless of intensity grade or relation to vaccination. Grade 3 was an event that prevented normal activities and related was defined as an unsolicited AE assessed by the investigator to be causally related to the study vaccination. | Within 30 days (Days 0 - 29) after any vaccination | 
| Number of Subjects Reporting Any and Related Serious Adverse Events (SAEs) | 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. Any was defined as occurrence of any symptom regardless of intensity grade or relation to vaccination and related was an event assessed by the investigator as causally related to the study vaccination. | Throughout the study period (from Day 0 up to Month 12) |
