About this study

Official title: A Phase 3, Open-Label Trial Evaluating the Safety, Tolerability, and Immunogenicity of a 13-valent Pneumococcal Conjugate Vaccine in Healthy Infants in Japan

The purpose of this study is to evaluate the safety, tolerability, and immunogenicity of the 13-valent pneumococcal conjugate vaccine (13vPnC) in infants of Japanese descent.

Being tested
13vPnC

What participants receive

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

  • 13vPnCBiological

    "First dose during 2 to 6 months of age Second dose at least 28 days after the first dose Third dose at least 28 days after the second dose Forth dose during 12 to 15 months of age"

What is being measured

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

  1. Percentage of Participants Achieving Antibody Level ≥ 0.35 μg/mL in the 13vPnC Group After the 3-Dose Infant Series

    Percentages of participants achieving World Health Organization (WHO) predefined antibody threshold ≥ 0.35 μg/mL along with the corresponding 95% CI for the 7 common pneumococcal serotypes (serotypes 4, 6B, 9V, 14, 18C, 19F, and 23F) and 6 additional pneumococcal serotypes specific to 13vPnC (serotypes 1, 3, 5, 6A, 7F, and 19A) are presented.

    Measured: one month after 3-dose infant series (at 7 months of age)

Secondary outcomes (3)
  1. Geometric Mean Antibody Concentration (GMC) in 13vPnC Group Relative After the 3-Dose Infant Series

    GMC as measured by enzyme-linked immunosorbent assay (ELISA) for 7 common pneumococcal serotypes (serotypes 4, 6B, 9V, 14, 18C, 19F, and 23F) and 6 additional pneumococcal serotypes specific to 13vPnC (Serotypes 1, 3, 5, 6A, 7F, and 19A) are presented.

    Measured: one mone month after 3-dose infant series (at 7 months of age)

  2. Percentage of Participants Achieving Antibody Level ≥ 0.35 μg/mL in the 13vPnC Group After the Toddler Dose

    Percentages of participants achieving World Health Organization (WHO) predefined antibody threshold ≥ 0.35 μg/mL along with the corresponding 95% CI for the 7 common pneumococcal serotypes (serotypes 4, 6B, 9V, 14, 18C, 19F, and 23F) and 6 additional pneumococcal serotypes specific to 13vPnC (serotypes 1, 3, 5, 6A, 7F, and 19A) are presented.

    Measured: one month after the toddler dose (at 12 - 15 months of age)

  3. Geometric Mean Antibody Concentration (GMC) in 13vPnC Group Relative After the Toddler Dose

    GMC as measured by enzyme-linked immunosorbent assay (ELISA) for 7 common pneumococcal serotypes (serotypes 4, 6B, 9V, 14, 18C, 19F, and 23F) and 6 additional pneumococcal serotypes specific to 13vPnC (Serotypes 1, 3, 5, 6A, 7F, and 19A) are presented.

    Measured: one month after the toddler dose (at 12-15 months of age)

Questions about this trial

What is this clinical trial studying?

A Phase 3 study testing 13vPnC in people with Vaccines, Pneumococcal Conjugate Vaccine, run by Wyeth is now a wholly owned subsidiary of Pfizer at 24 sites in Japan.

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 8 Aug 2012. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 24 sites in Japan. 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?

Yes. Results are posted in the registry (first posted 8 Aug 2012). 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 Achieving Antibody Level ≥ 0.35 μg/mL in the 13vPnC Group After the 3-Dose Infant Series (time frame: one month after 3-dose infant series (at 7 months of age)). 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 NCT00574795, 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 8 Aug 2012.
