About this study

Official title: Evaluation of the Persistence of the Immunity in 4-year-old Children Previously Immunised With an Adjuvanted Reduced Dose Inactivated Polio Vaccine, IPV-Al AJV (Picovax®) by Measuring the Response to an Additional Dose of IPV-Al AJV

The trial is a phase 4, open-label, multicentre clinical trial with healthy subjects who have been vaccinated with IPV-Al AJV at 2, 4, 6 and 15 18 months of age in previous trials. Levels of antibodies against poliovirus types 1, 2 and 3 after immunisation with IPV Al AJV will be measured in the trial subjects at the age of 4 years. An additional IPV-Al AJV dose (investigational vaccine) will be administered and the booster response to IPV-Al AJV will be investigated one month after administration.

What is being measured

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

  1. Seroprotection (titer ≥8) against poliovirus types 1, 2 and 3

    Individual serum titers against poliovirus types 1, 2 and three will be measured in collected serum samples

    Measured: One month after administration of an additional dose of IPV-Al AJV

Questions about this trial

What is this clinical trial studying?

A Phase 4 study testing IPV-Al in people with Poliomyelitis, run by AJ Vaccines A/S at 1 site in Panama.

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 9 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 Jun 2021. 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 Panama. 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?

Seroprotection (titer ≥8) against poliovirus types 1, 2 and 3 (time frame: One month after administration of an additional dose of IPV-Al AJV). 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 NCT04448132, 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 22 Jun 2021.
