About this study
Official title: 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).
Read the detailed description
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.

The research question as the sponsor registered it. This describes what the study plans to test, not what it found.
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).
