Cervical Intraepithelial Neoplasia | Efficacy and Immunogenicity Study of Recombinant Human Papillomavirus Bivalent(Type 16/18 )Vaccine

Cervical Intraepithelial Neoplasia research study

What is the primary objective of this study?

This is a Phase III clinical trial of the novel recombinant HPV 16/18 bivalent vaccine manufactured by Xiamen Innovax Biotech CO., LTD. The primary objective of this study is to demonstrate the efficacy of the vaccine against relevant outcomes in healthy women above 18 years old at enrolment. The secondary objectives are to evaluate the safety, immunogenicity and immuno-persistence of the vaccine. Meanwhile, this study tries to compare the difference of safety and immunogenicity among different lots. Approximately 6000 study subjects will be enrolled and randomly stratified into 2 groups and receive human papillomavirus (HPV) vaccine(three different lots) or commercialized hepatitis E vaccine(Hecolin) according to a 0-1-6 month schedule.
