About this study

Official title: A follow-on, Multi-centre, Open-label, Clinical, Phase 4 Trial to Investigate the Persistence of Serotype-specific Antibodies at 40 Months of Age in Children Who Have Received Either the 7-valent or the 13-valent Pneumococcal Conjugate Vaccine at 2, 4 and 12 Months of Age and Assessing the Immunogenicity of a 13-valent Pneumococcal Conjugate Vaccine Booster Dose Given at 40 Months of Age

This is a follow-on, multi-centre, open-label, clinical trial. The purpose of this trial is to investigate the concentrations of serotype-specific antibodies to IgG included in PCV13 in children who have received either the PCV7 or PCV13 primary immunisation at 2, 4 and 12 months of age. We intend to recruit all interested participants who completed the Wyeth-sponsored PCV13 infant trial study (6096A1-007) at selected study sites (i.e. those that recruited the majority of the children in the original study). The study will start in March 2010, at which time the eldest participants in the 6096A1-007 study will be approximately 42 months of age. There will be two visits per participant, 1 month apart from each other. At visit one, all participants will have a blood test and receive a dose of PCV13. At visit 2, all participants will have a blood test and will be offered the remaining pre-school booster vaccinations unless they have already received them.

What is being measured

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

  1. To assess the effectiveness of PCV13 booster vaccinations

    To assess the proportion of participants, immunised with the 13-valent pneumococcal conjugate vaccine (PCV13) at 2, 4 and 12 months of age, who have IgG concentrations ≥ 0.35mcg/ml for PCV13 serotypes at the time when preschool booster vaccinations are due (at 40 months of age).

    Measured: 1 month

Secondary outcomes (6)
  1. To assess IgG concentrations for PCV13 serotypes in children immunised with PCV7 and PCV13

    To assess the proportion of participants, immunised with the 7-valent pneumococcal conjugate vaccine (PCV7) at 2, 4 and 12 months of age, who have IgG concentrations ≥ 0.35mcg/ml for PCV13 serotypes at the time when preschool booster vaccinations are due (at 40 months of age) and comparing these to the proportion of participants achieving this threshold after infant immunisation with PCV 13.

    Measured: 1 month

  2. Compare PCV13 serotype-specific IgG geometric mean concentrations, opsonophagocytic activity geometric mean titres & the proportion of participants with PCV13 serotype-specific OPA titres ≥ 1:8 (at 40 months) when immunised in infancy with PCV7 or PCV13.

    Measured: 1 month

  3. Compare PCV serotype-specific IgG GMCs, OPA GMTs & proportion of participants with IgG concs ≥ 0.35mcg/ml & OPA titres ≥ 1:8 one month after booster dose of PCV13 at 40 months in children previously immunised with PCV7 & PCV13 at 2,4 & 12 months.

    Measured: 1 month

  4. To determine reactogenicity of the pre-school PCV13 booster in terms of rates of local and systemic reactions following vaccination.

    Measured: 1 month

  5. Investigate influence of genetic polymorphisms on the above immunological markers following infant immunisation with PCV7/PCV13 & following booster dose of PCV13 at 40 months & on the nature of adverse reactions observed after booster.

    Measured: 1 month

  6. Measure pneumococcal serotype-specific memory B cells frequencies before & 1 month after PCV13 dose (40 months) in subset previously immunised with PCV7/PCV13 at 2,4 & 12 months (serotype studies to include 4,14,23F (present in PCV7) & 1,3,19A).

    Measured: 1 month

Questions about this trial

What is this clinical trial studying?

A Phase 4 study testing PCV13 in people with Pneumococcal Disease, run by University of Oxford at 4 sites in United Kingdom.

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 5 inclusion and 11 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 22 Mar 2011. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 4 sites in United Kingdom. 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 4 studies take place after a treatment is approved, to learn more about its long-term benefits and risks in everyday use.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

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?

To assess the effectiveness of PCV13 booster vaccinations (time frame: 1 month). 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 NCT01095471, which also lists 2 linked publications.

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 22 Mar 2011; AzTrials last refreshed its copy on 6 Nov 2026.
