About this study

Official title: A Detailed Kinetics Study to Assess the Antibody and the B Cell Response to Either a 13-valent Conjugate Vaccine or a 23-valent Plain Pneumococcal Polysaccharide Vaccine Administered to Healthy Adults Without Prior Pneumococcal Vaccination

This is an open-label phase III clinical trial. The purpose of this trial is to investigate in detail the kinetics of the immune response to Prevenar-13, a pneumococcal conjugate vaccine, compared to Pneumovax-II, a pneumococcal plain polysaccharide vaccine. With their consent, healthy adults (n=2 in each group) aged over 18 years who have not received any pneumococcal vaccine in the past will receive either vaccine at their first visit. Blood will be taken before vaccination and at day 0,1,2,4,6,8,10,12,14,16,18,20,23,26,30,35 as well as 2,6 and 12 months following vaccination. With specific consent, a small volume of blood will be used to store DNA and RNA for analysis of the genetic associations with immune responses and adverse reactions to vaccines as well as the RNA expression following a vaccination. Serum or plasma will be used to assess antibody level and available whole blood will be used for B cell assays and to examine immunoglobulin gene usage in B cells.

What is being measured

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

  1. Frequency of serotype-specific B cell subsets determined by FACS.

    To assess and compare the kinetics of serotype-specific B cell subsets following a dose of PCV-13 or PPCV-23 given to healthy adults.

    Measured: within first month after vaccination

Secondary outcomes (1)
  1. Pneumococcal serotype-specific geometric mean concentrations (GMC)

    To assess and compare the kinetics of serotype-specific antibody (subclass) geometric mean concentrations (GMC) in response to a dose of PCV-13 or PPCV-23 given to healthy adults.

    Measured: within first month after vaccination

Questions about this trial

What is this clinical trial studying?

A Phase 3 study testing Prevenar 13 and Pneumovax II in people with Pneumococcal Disease, run by University of Oxford at 1 site 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 8 inclusion and 13 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 9 Nov 2015. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site 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 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?

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?

Frequency of serotype-specific B cell subsets determined by FACS. (time frame: within first month after vaccination). 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 9 Nov 2015.
