Study summary

This study aims to evaluate the persistence of anti-poliovirus antibodies in toddlers aged 18 months who were primed with oral polio vaccine (OPV) or inactivated polio vaccine (IPV) in the primary study. The study will also assess the immunogenicity and reactogenicity of a booster dose of IPV in subjects primed with three doses of IPV.

Read the detailed description

All subjects will also receive a booster dose of GSK Biologicals' DTPa/Hib vaccine (Infanrix+Hib) at Day 0. This vaccine will be provided as part of the local standard of care and will not be associated with any study endpoint.

What researchers measure

Primary outcomes

  1. Number of Subjects Seroprotected for Poliovirus Types 1, 2 and 3 Antibodies Above the Cut-off Value

    A seroprotected subject was defined as a vaccinated subject whose antibody titer is greater than or equal to (≥) 8 Effective Dose 50 (ED50). This outcome measure concerns subjects in the Poliorix Group only.

    Time frame: One month after Poliorix™ booster vaccination.

  2. Number of Subjects Seroprotected for Poliovirus Types 1, 2 and 3 Antibodies Above the Cut-off Value

    A seroprotected subject was defined as a vaccinated subject whose antibody titer is greater than or equal to (≥) 8 ED50.

    Time frame: Before booster vaccination.

  3. Antibody Titers Against Poliovirus Type 1, 2 and 3

    Antibody titers were summarized by geometric mean titers (GMTs) with their 95% confidence intervals (CIs). This outcome measure concerns subjects in the Poliorix Group only.

    Time frame: One month after Poliorix™ booster vaccination.

  4. Antibody Titers Against Poliovirus Type 1, 2 and 3.

    Antibody titers were summarized by geometric mean titers (GMTs) with their 95% CIs.

    Time frame: Before booster vaccination.

Secondary outcomes

  1. Number of Subjects With Any and Grade 3 Solicited Local Symptoms

    Solicited local symptoms assessed were pain, redness and swelling. Any = occurrence of the symptom regardless of intensity grade. Grade 3 pain = Cry when limb was moved/spontaneously painful. Grade 3 redness/swelling = redness/swelling spreading beyond 30 millimeters (mm) of injection site. This outcome measure concerns subjects in the Poliorix Group only.

    Time frame: Within 4-days (Days 0-3) post Poliorix™ booster vaccination.

  2. Number of Subjects With Any, Grade 3 and Related Solicited General Symptoms.

    Solicited general symptoms assessed include drowsiness, irritability, loss of appetite and fever \[defined as axillary temperature ≥ 37.1 degrees Celsius (°C)\]. Any = occurence of any general symptom regardless of their intensity grade or relationship to study vaccine. Grade 3 drowsiness = drowsiness that prevented normal activities. Grade 3 fever = fever (axillary temperature) \>39.0°C. Grade 3 irritability = crying that could not be comforted/ prevented normal activity. Grade 3 loss of appetite = not eating at all.

    Time frame: Within 4-days (Days 0-3) post Poliorix™ booster vaccination.

  3. Number of Subjects Reporting Any Unsolicited Adverse Events (AEs)

    An unsolicited AE covers any untoward medical occurrence in a clinical investigation subject temporally associated with the use of a medicinal product, whether or not considered related to the medicinal product. Any was defined as an adverse event (AE) reported in addition to those solicited during the clinical study. Any solicited symptom with onset outside the specified period of follow-up for solicited symptoms was reported as an unsolicited adverse event. This outcome measure concerns subjects in the Poliorix Group only.

Not marked actual or estimatedDates not marked actual or estimated

The record gives a start of Apr 2011, a primary completion of Sep 2011 and a completion of Sep 2011. It does not say whether these dates are actual or estimated.

Results were first posted in Dec 2016, 5 years 2 months after primary completion. A results delay was requested in Jul 2012.

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
No changes since tracking began. The registry record was last updated on Feb 11, 2019, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
