A Study to Evaluate the Immune Response and Safety of GSK Biologicals' HPV-16/18 L1 VLP AS04 Vaccine/Cervarix TM Vaccine in Healthy Females Aged 15-25 Years

Phase 3

Completed

• Conditions: Infections, Papillomavirus
• Interventions: Biological: Placebo; Biological: HPV-16/18 VLP/AS04 vaccine (Cervarix TM)

• Registration Number: NCT00485732
• Lead Sponsor: GlaxoSmithKline

Brief Summary

Human papillomavirus infection has clearly been recognized as the cause of cervical cancer. The infection of the cervix by certain oncogenic types of HPV, if not cleared, can lead to cervical cancer in women. This study will evaluate the immunogenicity and safety of the GSK Biologicals' HPV-16/18 L1 VLP AS04 vaccine (Cervarix TM) vaccine.

The Protocol Posting has been updated in order to comply with the FDA Amendment Act, Sep 2007.

• Pregnant or breastfeeding.
• Planning to become pregnant or likely to become pregnant.

Primary Outcome Measures

Name	Time	Method
Number of Subjects Seroconverted for Anti-human Papilloma Virus 16 (Anti-HPV-16) and Anti-human Papilloma Virus 18 (Anti-HPV-18) Antibodies	One month post Dose 3 (Month 7)	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.

Secondary Outcome Measures

Name	Time	Method
Number of Subjects Reporting Solicited General Symptoms	During the 7-day (Days 0-6) period following each vaccination	Solicited general symptoms assessed include arthralgia, fatigue, fever, gastrointestinal symptoms, headache, myalgia, rash, and urticaria.
Number of Subjects Reporting Serious Adverse Events (SAE)	From Day 0 up to Month 7	Serious adverse events assessed include medical occurrences that result in death, is 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 Pregnancies and Their Outcome	from Day 0 up to Month 7	Total: the total number of pregnancies in a group. The specific outcomes are also listed.
Anti-HPV-16 and Anti-HPV-18 Antibody Titres	Before vaccination (PRE) and one month post Dose 3 (Month 7)	Titres are given as geometric mean titres (GMTs) calculated on all subjects.
Number of Subjects Reporting Solicited Local Symptoms	During the 7-day (Days 0-6) period following each vaccination	Solicited local symptoms assessed include pain, redness and swelling at the injection site.
Number of Subjects Reporting Unsolicited Adverse Events (AE)	During the 30-day (Days 0-29) period following each vaccination	Unsolicited adverse event= Any adverse event (AE) reported in addition to those solicited during the clinical study. Also any "solicited" symptom with onset outside the specified period of follow-up for solicited symptoms was reported as an unsolicited adverse event.
Number of Subjects Reporting New Onset of Chronic Diseases (NOCDs) and Medically Significant Conditions	From Day 0 up to Month 7	NOCDs assessed include e.g. autoimmune disorders, asthma, type I diabetes. Medically significant AEs assessed include AEs prompting emergency room visits and physician office visits not related to common illnesses or Serious Adverse Events (SAEs) that are not related to common illnesses.
