About this study

Official title: The Durability of Protection Study of A Bivalent Human Papillomavirus (Type 16, 18) Recombinant Vaccine (E.Coli) in Healthy Women Aged 18 to 45 Years

The primary objective of this study is to evaluate the durability of protection of Recombinant Human Papillomavirus Bivalent (Types 16,18) Vaccine administered in females aged 18-45 years.

Read the detailed description

This is a follow-up study that is based on phase III clinical study of a recombinant human papillomavirus 16/18 bivalent vaccine in females aged 18-45 years (Unique Protocol ID: HPV-PRO-003, Identifiers: NCT01735006). The investigators will recruit people who have participated in phase III clinical study on Hebei Province before and to evaluate the durability of protection of the bivalent HPV vaccine on 90m and 114m after dose 1.

    Also called There is no other Intervention in this study

    The bivalent HPV-16/18 vaccine was a mixture of two aluminum hydroxide adjuvant-absorbed recombinant L1 VLPs of HPV-16 and HPV-18 expressed in E. coli. A 0.5 ml dose of the bivalent HPV test vaccine comprised 40 μg of HPV-16 and 20 μg of HPV-18 L1 VLPs absorbed with 208 μg of aluminum adjuvant

Study groups in NCT04969445
Study groupRoleWhat they receive
Vaccine groupParticipants in this arm have received 3 doses of HPV 16/18 bivalent vaccine that contains 40μg HPV 16 virus-like particle antigen and 20μg HPV 18 virus-like particle antigen adsorbed in alum-adjuvant.
Receives: Biological: Recombinant Human Papillomavirus Bivalent (Types 16, 18) Vaccine (Escherichia coli)
Control groupParticipants in this arm have received 3 doses of HEV vaccine that contains 30μg HEV virus-like particle antigen adsorbed in alum-adjuvant.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Number of Subjects With CIN2+ and/or VIN2+ and/or VaIN2+ Associated With HPV-16 and/or -18 Cervical Infection on 90m and 114m after dose 1

    To observe the number of Subjects With Histopathologically-confirmed CIN2+ and/or VIN2+ and/or VaIN2+ Associated With HPV-16 and/or -18 Cervical Infection on 90m and 114m after dose 1

    Measured: expected 2-3 years

  2. Number of Subjects With HPV-16 and/or -18 persistent cervical infection(6-month+ definition) on 90m and 114m after dose 1

    To detect the HPV16 and HPV18 DNA on the gynecological specimens ( Cervical exfoliated cell specimens and biopsy specimens) collected from the subjects

    Measured: expected 2-3 years
