Summary
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).

- 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.
