About this study

Official title: A Phase 3, Randomized, Modified Double-Blind, Active-Controlled Trial Evaluating The Safety, Tolerability, And Immunogenicity Of A 13-Valent Pneumococcal Conjugate Vaccine In Japanese Elderly Adults Aged 65 Years Old And Older Who Are Naive To Pneumococcal Vaccine

The purpose of this study is to evaluate the safety, tolerability and immunogenicity of a single dose of 13-valent pneumococcal conjugate vaccine compared to a single dose of 23-valent pneumococcal polysaccharide vaccine in Japanese adults aged 65 years old and older.

Being tested
13-valent pneumococcal conjugate vaccine, 23-valent pneumococcal polysaccharide vaccine

What is being measured

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

  1. Serotype-specific Opsonophagocytic Activity (OPA) Geometric Mean Titers (GMTs) for 12 Common Serotypes 1 Month After Vaccination

    Antibody-mediated serum OPA against each of the 12 pneumococcal serotypes (1, 3, 4, 5, 6B, 7F, 9V, 14, 18C, 19A, 19F, and 23F) was measured centrally using a quantitative functional microcolony OPA (mcOPA) assay. Results were expressed as OPA titers. OPA titers were logarithmically transformed for analysis; geometric means calculated and expressed as geometric mean titers (GMTs).

    Measured: One month after vaccination

  2. Percentage of Participants Achieving At Least a 4-fold Rise in OPA Titers for Serotype 6A 1 Month After Vaccination

    For serotype 6A the percentage of participants achieving at least a 4-fold rise on the serotype-specific antibody titer from pre-vaccination to 1 month post-vaccination was computed along with exact, 2-sided 95% confidence interval for the proportion.

    Measured: One month after vaccination

Secondary outcomes (1)
  1. Serotype-specific Opsonophagocytic Activity (OPA) Geometric Mean Titers (GMTs) for 12 Common Serotypes and Serotype 6A 1 Month After Vaccination

    Antibody-mediated serum OPA against each of the 13 pneumococcal serotypes (1, 3, 4, 5, 6A, 6B, 7F, 9V, 14, 18C, 19A, 19F, and 23F) was measured centrally using a quantitative functional microcolonoy OPA (mcOPA) assay. Results were expressed as OPA titers. OPA titers were logarithmically transformed for analysis; geometric means calculated and expressed as geometric mean titers (GMTs).

    Measured: One month after vaccination

Questions about this trial

What is this clinical trial studying?

A Phase 3 study testing 13-valent pneumococcal conjugate vaccine and 23-valent pneumococcal polysaccharide vaccine in people with Pneumococcal Vaccines and Pneumococcal Conjugate Vaccine, run by Pfizer at 8 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 4 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 20 Sep 2013. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 8 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 20 Sep 2013). 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?

Serotype-specific Opsonophagocytic Activity (OPA) Geometric Mean Titers (GMTs) for 12 Common Serotypes 1 Month After Vaccination (time frame: One month after vaccination). The study lists 2 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?
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 20 Sep 2013.
