Evaluation of Long-term Immunogenicity and Safety of a Human Papillomavirus (HPV) Vaccine in Healthy Female Subjects.

Follow-up Study to Evaluate the Long-term Immunogenicity and Safety of a HPV Vaccine (GSK 580299) in Healthy Female Subjects

Infection with human papillomavirus (HPV) has been clearly established as the necessary cause of cervical cancer. This study is designed to evaluate the long-term immunogenicity and safety of the 580299 HPV vaccine up to 10 years after administration of the first dose of HPV vaccine (Month 0) administered in the primary study 580299/013. This protocol posting deals with objectives & outcome measures of the extension phase from Month 60 to Month 120. The objectives & outcome measures of the primary phase are presented in a separate protocol posting (NCT00196924). The objectives & outcome measures of the extension phase up to Month 48 are presented in a separate protocol posting (NCT00316706).

Subjects were aged 10-14 years at the time of entry into the primary study. No vaccine will be administered in this extension study.

Results on outcome measures describing analyses on other studies are not reported in this record. Please refer to the records mentioned in the respective outcome measure titles.

Inclusion Criteria:

• Subjects who the investigator believes that they and/or their parents or legally acceptable representative (LAR) can and will comply with the requirements of the protocol should be enrolled in the study.
• A female enrolled in the immunogenicity subset of study 580299-013, who received three doses of HPV vaccine and participated in the extension study of 580299-013.
• Written informed assent obtained from the subject. For subjects below the legal age of consent, written informed consent must be obtained from a parent or legally acceptable representative of the subject.

Exclusion Criteria:

• 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.
• Use of any investigational or non-registered product (drug or vaccine) or planned use during the study period.
• Administration or planned administration of any HPV vaccine, other than the vaccine administered in study 580299-013.
• Chronic administration of immunosuppressants or other immune-modifying drugs occurring within the three months preceding study entry.
• Administration of immunoglobulins and/or any blood products occurring within the three months preceding study entry.
