What is being measured

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

  1. Number of Participants Who Seroconvert to HPV 6.

    Vaccine-induced anti-HPV 6 seroconversion following administration of a 3-dose regimen of GARDASIL® in females 9 to 23 years of age in Korea. Seroconversion for HPV 6 was defined as achieving an anti-HPV cLIA (Competitive Luminex immunoassay) level of at least 20 mMU/mL.

    Measured: Week 4 Postdose 3

  2. Number of Participants Who Seroconvert to HPV 11.

    Vaccine-induced anti-HPV 11 seroconversion following administration of a 3-dose regimen of GARDASIL® in females 9 to 23 years of age in Korea. Seroconversion for HPV 11 was defined as achieving an anti-HPV cLIA (Competitive Luminex immunoassay) level of at least 16 mMU/mL.

    Measured: Week 4 Postdose 3

  3. Number of Participants Who Seroconvert to HPV 16.

    Vaccine-induced anti-HPV 16 seroconversion following administration of a 3-dose regimen of GARDASIL® in females 9 to 23 years of age in Korea. Seroconversion for HPV 16 was defined as achieving an anti-HPV cLIA (Competitive Luminex immunoassay) level of at least 20 mMU/mL.

    Measured: Week 4 Postdose 3

  4. Number of Participants Who Seroconvert to HPV 18.

    Vaccine-induced anti-HPV 18 seroconversion following administration of a 3-dose regimen of GARDASIL® in females 9 to 23 years of age in Korea. Seroconversion for HPV 18 was defined as achieving an anti-HPV cLIA (Competitive Luminex immunoassay) level of at least 24 mMU/mL.

    Measured: Week 4 Postdose 3

Secondary outcomes (1)
  1. Number of Participants With Adverse Experiences

    Number of participants who reported 1 or more adverse experience.

    Measured: Overall study including 14 calendar days after the last vaccination visit.

Questions about this trial

What is this clinical trial studying?

A Phase 3 study testing Gardasil™ in people with Papillomavirus Infections, run by Merck Sharp & Dohme LLC.

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 2 inclusion and 5 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 4 Feb 2016. Status can change between updates, so confirm with the study contact before making plans.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. Some participants in this study may receive a placebo. 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?

Yes. Results are posted in the registry (first posted 14 Sep 2010). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.

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?

Number of Participants Who Seroconvert to HPV 6. (time frame: Week 4 Postdose 3). The study lists 4 primary outcomes in all. 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 NCT00157950, which also lists 2 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 4 Feb 2016.
