About this study

Official title: Immunogenicity and Safety of Gardasil-9 and Cervarix When Administered to 9-10-year-old Subjects According to 0-6 Month Schedule

A ninevalent HPV vaccine (Gardasil-9) has been recently approved for clinical use. No data on immunogenicity and safety of interchangeable use of the ninevalent and the bivalent vaccine (Cervarix) are available. The main objective of this study is to assess the immunogenicity of ninevalent and bivalent HPV vaccines when administered to 9-10-year-old girls and boys according to 0-6 month schedule.

Read the detailed description

The proportion of subjects with detectable antibodies and antibody geometrical mean titers to 9 HPV genotypes included in the Gardasil-9 vaccine will be assessed 1 and 6 months post-first dose and 1, 18 and 36 months post-second dose of vaccine.

Being tested
Immunogenicity two doses of Gardasil-9, Immunogenicity Cervarix and Gardasil-9
Keywords
HPV vaccines, interchangeable use

What participants receive

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

  • Immunogenicity two doses of Gardasil-9Biological

    Also called HPV vaccine

    Subjects will receive two standard doses of Gardasil-9 (0.5 ml)

  • Immunogenicity Cervarix and Gardasil-9Biological

    Also called HPV vaccine

    Subjects will receive a standard dose of Cervarix (0.5 ml) and a standard dose of Gardasil-9 (0.5 ml)

What is being measured

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

  1. Comparison of proportion of subjects with detectable antibodies to 9 HPV genotypes included in the Gardasil-9 vaccine observed in two study arms

    A Luminex Total IgG assay will be used to assess the presence of antibodies and antibody titers to 9 HPV genotypes included in the Gardasil-9 vaccine. Luminex Units will be used for the antibody titers assessment.

    Measured: 36 months post-second dose of vaccine

Secondary outcomes (1)
  1. Comparison of tolerability profile of Gardasil-9 and Cervarix

    Local and general symptoms observed after each vaccine dose will be assessed by using a standardized diary card. Proportion of subjects who reported local and/or general symptoms will be compared.

    Measured: During 5 days after each vaccine dose administration.

Questions about this trial

What is this clinical trial studying?

A Phase 3 study testing Immunogenicity two doses of Gardasil-9 and Immunogenicity Cervarix and Gardasil-9 in people with HPV Vaccines Immunogenicity and Safety, run by Laval University at 1 site in Canada.

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 1 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: finished, as of the sponsor's last update on 18 Jan 2019. 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 Canada. 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.

What does this phase mean?

Phase 3 studies compare the treatment with the current standard treatment or a placebo in a large group, to confirm how well it works and watch for side effects.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

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?

Comparison of proportion of subjects with detectable antibodies to 9 HPV genotypes included in the Gardasil-9 vaccine observed in two study arms (time frame: 36 months post-second dose of vaccine). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT02567955, which also lists 3 linked publications.

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 18 Jan 2019.
