What is being measured

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

  1. Geometric Mean Fold Rise (GMFR) for Serotype-specific Pneumococcal Immunoglobulin G (IgG) Antibody From 1 Month After Dose 2 of 13vPnC to 1 Month After Dose 3 of 13vPnC

    Geometric mean fold rises (GMFRs) for the 13 serotypes (1, 3, 4, 5, 6A, 6B, 7F, 9V, 14, 18C, 19A, 19F, and 23F) from 1 month post-dose 2 to 1 month post-dose 3 were computed using the logarithmically transformed assay results. Confidence interval (CI) for the GMFRs were back transformations of a CI based on the Student t distribution for the logarithmically transformed assay results.

    Measured: 1 month post-dose 2, 1 month post-dose 3

Secondary outcomes (6)
  1. Geometric Mean Concentration (GMC) for Serotype-specific Pneumococcal Immunoglobulin G (IgG) Antibody 1 Month After Dose 3 of 13vPnC Relative to 1 Month After Dose 2 of 13vPnC

Geometric means (GMs) were calculated using all participants with available data for both post-dose 2 and post-dose 3 blood draws.

    Measured: 1 month post-dose 2, 1 month post-dose 3

  2. Geometric Mean Concentration (GMC) for Serotype-specific Pneumococcal Immunoglobulin G (IgG) Antibody 1 Month After Dose 2 of 13vPnC Relative to 1 Month After Dose 1 of 13vPnC

    Antibody GMC for the 13 pneumococcal serotypes (1, 3, 4, 5, 6A, 6B, 7F, 9V, 14, 18C, 19A, 19F, and 23F) were presented. GMC (13vPnC) and corresponding 2-sided 95% CI were evaluated. GMs were calculated using all participants with available data for both post-dose 1 and post-dose 2 blood draws.

    Measured: 1 month post-dose 1, 1 month post-dose 2

  3. Serotype-Specific Pneumococcal Opsonophagocytic Activity (OPA) Geometric Mean Titers (GMTs) 1 Month After Dose 3 of 13vPnC Relative to 1 Month After Dose 2 of 13vPnC

GMT (13vPnC) and corresponding 2-sided 95% CI were evaluated. GMs were calculated using all participants with available data for both post-dose 2 and post-dose 3 blood draws.

    Measured: 1 month post-dose 2, 1 month post-dose 3

  4. Serotype-Specific Pneumococcal Opsonophagocytic Activity (OPA) Geometric Mean Titers (GMTs) 1 Month After Dose 2 of 13vPnC Relative to 1 Month After Dose 1 of 13vPnC

GMT (13vPnC) and corresponding 2-sided 95% CI were evaluated. GMs were calculated using all participants with available data for both post-dose 2 and post-dose 3 blood draws.

    Measured: 1 month post-dose 1, 1 month post-dose 2

  5. Serotype-Specific Pneumococcal Opsonophagocytic Activity (OPA) Geometric Mean Fold Rise (GMFR) From 1 Month After Dose 2 of 13vPnC to 1 Month After Dose 3 of 13vPnC

    Measured: 1 month post-dose 2, 1 month post-dose 3

  6. Serotype-Specific Pneumococcal Opsonophagocytic Activity (OPA) Geometric Mean Fold Rise (GMFR) From 1 Month After Dose 1 of 13vPnC to 1 Month After Dose 2 of 13vPnC

    GMFRs for the 13 serotypes (1, 3, 4, 5, 6A, 6B, 7F, 9V, 14, 18C, 19A, 19F, and 23F) from 1 month post-dose 1 to 1 month post-dose 2 were computed using the logarithmically transformed assay results.

Questions about this trial

What is this clinical trial studying?

A Phase 3 study testing 13-valent pneumococcal conjugate vaccine and Blood draw in people with HIV Infections and Pneumococcal Infections, run by Pfizer at 15 sites in United States.

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 9 inclusion and 22 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 10 Jun 2013. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 15 sites in United States. 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 10 Jun 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?

Geometric Mean Fold Rise (GMFR) for Serotype-specific Pneumococcal Immunoglobulin G (IgG) Antibody From 1 Month After Dose 2 of 13vPnC to 1 Month After Dose 3 of 13vPnC (time frame: 1 month post-dose 2, 1 month post-dose 3). 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 NCT00963235, 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 10 Jun 2013.
