About this study

Official title: Immuno-persistence Study of A Bivalent Human Papillomavirus (Type 16, 18) Recombinant Vaccine (E.Coli) in Healthy Female Subjects Aged 9 to 17 Years

The primary objective of this study is to evaluate the immuno-persistence (type specific IgG antibody) of the tested vaccine administered in girls aged 9-17 years,comparing to young healthy adults of 18-26 years who received the standard 3-dose schedule (0,1,6 months).

Read the detailed description

This is a follow-up study that is based on the bridging study of a recombinant human papillomavirus 16/18 bivalent vaccine in preadolescent girls(Unique Protocol ID:HPV-PRO-006,Identifiers: NCT02562508) .The investigators will recruit people who have participated in bridging study before and collect their serum samples to test the seroprevalence and geometric mean concentrations of anti-HPV16 and anti-HPV18 antibody on 54 months after dose 1

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • Recombinant Human Papillomavirus Bivalent (Types 16, 18) Vaccine (Escherichia coli)Drug

    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

What is being measured

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

  1. Anti-HPV16 and anti-HPV18 seroprevalence and geometric mean concentrations at Month 54 (type-specific IgG antibody)

    To detect the anti-HPV 16 and anti-HPV 18 type-specific IgG antibody level on 54 month after the dose 1

    Measured: Month 54

Secondary outcomes (1)
  1. Anti-HPV16 and anti-HPV18 seroprevalence and geometric mean concentrations at Month 54 (type specific neutralizing antibody)

    To detect the anti-HPV 16 and anti-HPV 18 type specific neutralizing antibody level on 54 month after the dose 1

    Measured: Month 54

Questions about this trial

What is this clinical trial studying?

An observational study of Cervical Intraepithelial Neoplasia and Cervical Cancer, run by Jun Zhang at 1 site in China.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 3 inclusion and 3 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: status not confirmed, as of the sponsor's last update on 26 Jan 2023. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in China. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

Results are not available in the source record.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Anti-HPV16 and anti-HPV18 seroprevalence and geometric mean concentrations at Month 54 (type-specific IgG antibody) (time frame: Month 54). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 26 Jan 2023.
