Immuno-persistence Study of a Recombinant Human Papillomavirus 16/18 Bivalent Vaccine in Preadolescent Girls

January 3, 2019 updated by: Jun Zhang

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).

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

Detailed Description

This is a follow-up study which 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) .We 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 18 and 30 months after dose 1.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

10 years to 28 years (ADULT, CHILD)

Accepts Healthy Volunteers

Yes

Genders Eligible for Study

Female

Sampling Method

Non-Probability Sample

Study Population

Participants who participated in the bridging study (Unique Protocol ID:HPV-PRO-006-2, Identifiers: NCT02562508) and received at least one dose will be recruited.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Anti-HPV16 and anti-HPV18 seroprevalence and geometric mean concentrations at Months 18 and 30 (type specific IgG antibody)
Time Frame: Month 18 and 30
To detect the anti-HPV 16 and anti-HPV 18 type specific IgG antibody level on 18 and 30 months after the dose 1
Month 18 and 30

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Anti-HPV16 and anti-HPV18 seroprevalence and geometric mean concentrations at Months 18 and 30 (type specific neutralizing antibody)
Time Frame: Month 18 and 30
To detect the anti-HPV 16 and anti-HPV 18 type specific neutralizing antibody level on 18 and 30 months after the dose 1
Month 18 and 30
All the Serious Adverse Events(SAE) occurred during clinical trial time frame would be recorded
Time Frame: between 7 months and 30months after the dose1
between 7 months and 30months after the dose1

Primary Completion (ACTUAL)

Primary Completion

The date on which the last participant in a clinical study was examined or received an intervention to collect final data for the primary outcome measure. Whether the clinical study ended according to the protocol or was terminated does not affect this date. For clinical studies with more than one primary outcome measure with different completion dates, this term refers to the date on which data collection is completed for all the primary outcome measures. The "anticipated" primary completion date is the date that the researchers think will be the primary completion date for the study.
