About this study

Official title: A Phase III Open-label, Safety, Tolerability and Immunogenicity Study of a 9-Valent Human Papillomavirus (HPV) L1 Virus-Like Particle (VLP) Vaccine Administered to 9- to 15-Year-Old Japanese Preadolescent and Adolescent Girls

This study will evaluate the safety, tolerability, and immunogenicity of V503 in Japanese girls between the ages of 9 and 15 and will determine whether V503 induces an acceptable immune response to all human papillomavirus (HPV) strains contained in the vaccine. The success criterion for the primary analysis requires that point estimates for seroconversion rate be greater than 90% for all 9 HPV types.

What is being measured

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

  1. Percentage of Participants Who Seroconvert to Each of the HPV Types Contained in the Vaccine

    Serum antibody titers for HPV virus-like particles (VLPs), Types 6, 11, 16, 18, 31, 33, 45, 52 and 58 were determined 4 weeks post-vaccination 3 using competitive luminex immunoassay (cLIA). The serostatus cutoffs (milli Merck U/mL) for HPV types were as follows: HPV Type 6: ≥30, HPV Type 11: ≥16; HPV Type 16: ≥20, HPV Type 18: ≥24, HPV Type 31: ≥10, HPV Type 33: ≥8, HPV Type 45: ≥8, HPV Type 52: ≥8, and HPV Type 58: ≥8.

    Measured: 4 weeks post-vaccination 3 (Month 7)

  2. Percentage of Participants With an Injection-site Adverse Event (AE)

    An AE is defined as any unfavorable and unintended change in the structure, function, or chemistry of the body temporally associated with the use of the study vaccine, whether or not considered related to the use of the vaccine. Any worsening of a preexisting condition which is temporally associated with the use of the study vaccine is also an AE. AEs such as redness, swelling, and pain/tenderness/soreness at the injection site were recorded.

    Measured: up to 5 days after any vaccination

  3. Percentage of Participants With a Non-Injection Site (Systemic) AE

    An AE is defined as any unfavorable and unintended change in the structure, function, or chemistry of the body temporally associated with the use of the study vaccine, whether or not considered related to the use of the vaccine. Any worsening of a preexisting condition which is temporally associated with the use of the study vaccine is also an AE. Systemic AEs were those not categorized as injection-site AEs.

    Measured: up to 15 days after any vaccination

  4. Percentage of Participants With a Vaccine-related AE

    An AE is defined as any unfavorable and unintended change in the structure, function, or chemistry of the body temporally associated with the use of the study vaccine, whether or not considered related to the use of the vaccine. Any worsening of a preexisting condition which is temporally associated with the use of the study vaccine is also an AE. Adverse experience that is judged by the Investigator to be "definitely related," "probably related," or "possibly related" to the study drug is defined as a vaccine-related AE.

    Measured: up to 15 days after any vaccination

Secondary outcomes (1)
  1. Geometric Mean Titers (GMTs) for Each of the HPV Types Contained in the Vaccine

    Serum antibody titers for HPV virus-like particles (VLPs), Types 6, 11, 16, 18, 31, 33, 45, 52 and 58 were determined 4 weeks post-vaccination 3 using cLIA. Titers are reported in milli Merck Units/mL.

    Measured: 4 weeks post-vaccination 3 (Month 7)

Questions about this trial

What is this clinical trial studying?

A Phase 3 study testing V503 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 4 inclusion and 12 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 28 Nov 2018. 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. 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 22 Dec 2014). 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?

Percentage of Participants Who Seroconvert to Each of the HPV Types Contained in the Vaccine (time frame: 4 weeks post-vaccination 3 (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 NCT01254643, 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 28 Nov 2018.
