A Bridging Study of a Recombinant Human Papillomavirus 16/18 Bivalent Vaccine in Preadolescent Girls

August 15, 2018 updated by: Jun Zhang

Immunogenicity and Safety Study of a Bivalent Human Papillomavirus (Type 16, 18) Recombinant Vaccine (E.Coli) in Healthy Female Subjects Aged 9 to 17 Years

This is a bridging trial of the recombinant HPV 16/18 bivalent vaccine manufactured by Xiamen Innovax Biotech CO., LTD.The primary objective of this study is to evaluate the immunogenicity (type specific IgG antibody) and safety of the tested vaccine administered in girls aged 9-17 years is non-inferior to young healthy adults of 18-26 years according to the standard 3-dose schedule (0,1,6 months). Meanwhile, this study tries to compare the difference of safety and immunogenicity among different schedules (0-6m vs 0-1-6m).

Study Overview

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

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

Totally 750 healthy girls of 9-17 years and 225 healthy young women of 18-26 years were enrolled. The subjects of 9-14 years will be stratified into 2 subset. Subjects in each subsets will be randomly assigned into the standard 0-1-6m schedule group or an alternative 0-6m group. All subjects of 15-26 years of age will receive the standard 0-1-6m schedule. Participants were actively monitored for adverse events for 1 month after each injection. Severe adverse events during the trial were followed up. Serum samples from all the subjects would be collected on day 0, 6m, 7m to evaluate the immunogenicity.
