What is being measured

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

  1. Human Papilloma Virus (HPV) 6 Serum Antibody Titer at One Month After Completed Vaccination Series

    Month 7 HPV Competitive Luminex immunoassay (cLIA) Geometric Mean Titers (GMT) by vaccine group.

    The limit of detection of the assay was 7 mMU/ml. GMTs and confidence limits below the limit of detection are shown as "7.0".

    Measured: At one month after completed vaccination series (Month 7)

  2. Human Papilloma Virus (HPV) 11 Serum Antibody Titer at One Month After Completed Vaccination Series

    Month 7 HPV Competitive Luminex immunoassay (cLIA) Geometric Mean Titers by vaccine group.

    The limit of detection of the assay was 8 mMU/ml. GMTs and confidence limits below the limit of detection are shown as "8.0".

    Measured: At one month after completed vaccination series (Month 7)

  3. Human Papilloma Virus (HPV) 16 Serum Antibody Titer at One Month After Completed Vaccination Series

    Month 7 HPV Competitive Luminex immunoassay (cLIA) Geometric Mean Titers by vaccine group.

    The limit of detection of the assay was 11 mMU/ml. GMTs and confidence limits below the limit of detection are shown as "11.0".

    Measured: At one month after completed vaccination series (Month 7)

  4. Human Papilloma Virus (HPV) 18 Serum Antibody Titer at One Month After Completed Vaccination Series

    Month 7 HPV Competitive Luminex immunoassay (cLIA) Geometric Mean Titers by vaccine group.

    The limit of detection of the assay was 10 mMU/ml. GMTs and confidence limits below the limit of detection are shown as "10.0".

    Measured: At one month after completed vaccination series (Month 7)

Secondary outcomes (1)
  1. HPV 6, 11, 16 and 18 Serum Antibody Titer at 24 Month After Completed Vaccination Series

    Month 30 HPV cLIA Geometric Mean Titers by vaccine group.

    Measured: 24 month after completed vaccination series (Month 30)

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing Quadrivalent Human Papillomavirus (Types 6, 11, 16, 18) Recombinant Vaccine (V501) in people with HPV 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 1 inclusion and 1 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 21 Apr 2017. 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 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.

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 18 Aug 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?

Human Papilloma Virus (HPV) 6 Serum Antibody Titer at One Month After Completed Vaccination Series (time frame: At one month after completed vaccination series (Month 7)). 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 NCT00411749, which also lists 1 linked publication.

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 21 Apr 2017.
