About this study

Official title: A Randomized Controlled Trial to Compare a 1-dose vs. 2-dose Priming Schedule of 13-valent Pneumococcal Conjugate Vaccine in Canadian Infants; a Canadian Immunization Research Network (CIRN) Study

This study is assessing if a reduced dosing schedule (1+1) of the 13-valent pneumococcal conjugate vaccine (PCV13) is non-inferior to the currently used schedule used in most of Canada.The vaccine is currently usually given as 3 doses at 2, 4 and 12 months of age. This study aims to find out if it is possible to achieve the same protection using just 2 doses, at 2 and 12 months.

What is being measured

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

  1. Immunogenicity of PCV13 post-booster

    Serotype-specific pneumococcal IgG concentration at 1 month post-booster dose

    Measured: 13 months of age

Secondary outcomes (4)
  1. Immunogenicity of PCV13 post-priming

    Serotype-specific pneumococcal IgG concentration post-priming dose(s)

    Measured: 5 months of age

  2. Proportion of protected infants post-booster

    Proportion of infants achieving serotype-specific pneumococcal IgG concentration ≥0.35 µg/ml post-booster dose

    Measured: 13 months of age

  3. Proportion of protected infants post-priming

    Proportion of infants achieving serotype-specific pneumococcal IgG concentration ≥0.35 µg/ml post-priming dose(s)

    Measured: 5 months of age

  4. Incidence of adverse events following PCV13

    Adverse events following immunization after doses of PCV13

    Measured: 2, 4 and 12 months of age

Questions about this trial

What is this clinical trial studying?

A Phase 2/3 study testing PCV13 in people with Invasive Pneumococcal Disease, Protection Against and Streptococcus Pneumoniae Infection, run by University of British Columbia at 1 site in Canada.

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 3 inclusion and 34 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 4 Mar 2024. 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 Canada. 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 combined phase mean?

Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.

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?

Immunogenicity of PCV13 post-booster (time frame: 13 months of age). 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 4 Mar 2024.
