About this study

Official title: Immunogenicity and Reactogenicity of 13-valent Pneumococcal Conjugate Vaccine Among Infants, Toddlers and Children in Bobo-Dioulasso, Burkina Faso: a Phase 4 Randomized Trial

This study aims to evaluate the immunogenicity and reactogenicity of 13-valent pneumococcal conjugate vaccine among infants, toddlers and children in Bobo-Dioulasso, Burkina Faso. Infants will be randomized to receive vaccine at 6, 10, 14 weeks or at 6 weeks, 14 weeks and 9 months of age. Serotype-specific serum IgG, OPA and nasopharyngeal colonization will be assessed at 6 weeks, 18 weeks, 9 months and 10 months of age. Toddlers 12-15 months of age will be randomized to receive either a single dose of PCV13 or 2 doses 2 months apart. Serotype-specific serum IgG and OPA will be measured pre-dose 1 and again 3 months later. Children 2 to 4 years of age will receive a single dose of PCV13 and have IgG and OPA assessments pre-vaccination and 1 month post-vaccination.

The immunogenicity and reactogenicity of PCV13 in the "standard schedule" groups (e.g. 6, 10, 14 weeks for infants and single dose for toddlers) will be compared to that observed in the PCV13 licensure trials. Within each age group the alternative schedule will be compared to the standard schedule in terms of immunogenicity and impact on nasopharyngeal carriage (infants only).

What is being measured

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

  1. Serotype-specific pneumococcal serum IgG

    Primary outcome in other age groups is:

    • 3 months post-dose 1 (toddlers)
    • 1 month post-vaccination (children)

    Measured: 18 weeks for infants

Secondary outcomes (4)
  1. Serotype-specific pneumococcal serum OPA

    Measured: 18 weeks, 9 months and 10 months (infants), 3 months post-dose 1 (toddlers), 1 month post-vaccination (children)

  2. Vaccine-type and non-vaccine type pneumococcal nasopharyngeal carriage

    Measured: 18 weeks, 9 months and 10 months (infants)

  3. Adverse events following immunization

    Measured: 1 and 3 days after each dose of vaccine (active surveillance), up to 28 days post-vaccination (passive surveillance)

  4. Serotype-specific serum IgG

    Measured: in infants, at 9 months and 10 months of age

Questions about this trial

What is this clinical trial studying?

A Phase 4 study testing Prevnar13 (manufactured by Pfizer) in people with Pneumococcal Infections, run by Agence de Médecine Préventive, France at 4 sites in Burkina Faso.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

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 6 Mar 2017. 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 Burkina Faso. 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?

Serotype-specific pneumococcal serum IgG (time frame: 18 weeks for infants). 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 6 Mar 2017.
