Study summary

The primary objective of this study is to evaluate the durability of protection and immuno-persistence 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 before and to evaluate the durability of protection and immuno-persistence of the bivalent HPV vaccine on 90m and 114m after dose 1.

Exclusion criteria

Exclusion Criteria:

  1. Participants used other HPV vaccine products (including both marketed and unmarketed vaccines) since participating in the Phase III clinical study.
  2. According to the investigator's judgment, there might be some medical, psychological, social or occupational factors which might impact on the individual to obey the protocol or sign the ;
Terms in these criteria, in plain language(1)

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.

Informed consent

Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.

You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.

Groups and cohorts

  • Vaccine group

    Participants 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.

    Biological: Recombinant Human Papillomavirus Bivalent (Types 16, 18) Vaccine (Escherichia coli)

  • Control group

    Participants in this arm have received 3 doses of HEV vaccine that contains 30μg HEV virus-like particle antigen adsorbed in alum-adjuvant.

Interventions

  • 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

What researchers measure

Primary outcomes

  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

    Time frame: 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

    Time frame: expected 2-3 years

Secondary outcomes

  1. Anti-HPV16 and anti-HPV18 type-specific IgG antibody level on 90m and 114m after dose 1

    To detect the anti-HPV 16 and anti-HPV 18 seroconversion rates and geometric mean concentrations on 90m and 114m after dose 1

    Time frame: expected 2-3 years
