Evaluation of Safety and Immunogenicity of Co-administering Human Papillomavirus (HPV) Vaccine With Other Vaccines in Healthy Female Subjects

Phase 3
Completed
Conditions
Infections, Papillomavirus
Interventions
Biological: Boostrix ® Polio
Biological: GSK Biologicals' HPV-16/18 L1 AS04 vaccine (Cervarix TM)
Registration Number
NCT00426361
Lead Sponsor
GlaxoSmithKline
Brief Summary

Infection with human papillomavirus (HPV) has been clearly established as the central cause of cervical cancer. Vaccination of pre-teens and adolescents, ideally before sexual debut and thus before exposure to oncogenic HPV, is a rational strategy for prevention of cervical cancer, and so HPV vaccination could complement the existing pre-adolescent/adolescents platform. Therefore, this Phase IIIb study is designed to evaluate the safety and immunogenicity of co-administering Boostrix polio (dTpa-IPV) with GSK Biologicals' (580299)HPV-16/18 L1 AS04 vaccine (Cervarix TM) as compared to the administration of either vaccine alone.

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