GSK Clinical Trials

This is a multicenter study in which women are planned to receive either the HPV vaccine or control. Study participation will last approximately 72 months and involves a total of thirteen or fourteen scheduled visits.

Originally, the study was planned for 24 months. It was then extended for 2 more years with 4 additional visits (study end at Month 48).

The protocol posting has been updated as the study was extended by additional 2 years with two or three additional visits (study end at Month 72) for subjects who consent to participate in the extension.

This protocol posting has been updated following protocol amendment 6 dated 24 April 2014.

Safety data presented here were assessed for all vaccinated subjects for whom data were available at the time of the event-triggered analysis irrespective of the initial (Month 0) HPV-16 or HPV-18 serostatus and DNA status.

Subjects received 3 doses of Cervarix vaccine. Cervarix vaccine was administered intramuscularly in the deltoid muscle of the non-dominant arm according to a 0, 1, 6-month schedule.
