Immunogenicity and Safety of Booster Dose of PoliorixTM Vaccine in Previously Vaccinated Toddlers

September 18, 2018 updated by: GlaxoSmithKline

Immunogenicity and Safety of a Booster Dose of GlaxoSmithKline Biologicals' IPV (PoliorixTM) in Healthy Chinese Toddlers

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.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Number of Subjects Seroprotected for Poliovirus Types 1, 2 and 3 Antibodies Above the Cut-off Value
Time Frame: One month after Poliorix™ booster vaccination.
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.
One month after Poliorix™ booster vaccination.
Number of Subjects Seroprotected for Poliovirus Types 1, 2 and 3 Antibodies Above the Cut-off Value
Time Frame: Before booster vaccination.
A seroprotected subject was defined as a vaccinated subject whose antibody titer is greater than or equal to (≥) 8 ED50.
Before booster vaccination.
Antibody Titers Against Poliovirus Type 1, 2 and 3
Time Frame: One month after Poliorix™ booster vaccination.
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.
One month after Poliorix™ booster vaccination.
Antibody Titers Against Poliovirus Type 1, 2 and 3.
Time Frame: Before booster vaccination.
Antibody titers were summarized by geometric mean titers (GMTs) with their 95% CIs.
Before booster vaccination.

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Number of Subjects With Any and Grade 3 Solicited Local Symptoms
Time Frame: Within 4-days (Days 0-3) post Poliorix™ booster vaccination.
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.
Within 4-days (Days 0-3) post Poliorix™ booster vaccination.
Number of Subjects With Any, Grade 3 and Related Solicited General Symptoms.
Time Frame: Within 4-days (Days 0-3) post Poliorix™ booster vaccination.
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. Related = symptom assessed by the investigator as causally related to the vaccination. This outcome measure concerns subjects in the Poliorix Group only.
Within 4-days (Days 0-3) post Poliorix™ booster vaccination.
Number of Subjects Reporting Any Unsolicited Adverse Events (AEs)
Time Frame: Within the 31-day (Days 0-30) follow-up period after the Poliorix™ booster vaccination.
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.
Within the 31-day (Days 0-30) follow-up period after the Poliorix™ booster vaccination.
Number of Subjects With Serious Adverse Events (SAEs)
Time Frame: During the entire study period (Day 0 to Month 1).
Serious adverse events (SAEs) assessed include medical occurrences that resulted in death, were life threatening, required hospitalization or prolongation of hospitalization or resulted in disability/incapacity.
