Assess Reacto- and Immunogenicity of Pneumococcal Conjugate Vaccine When Given as Booster or a 2 Dose Catch up Schedule

June 8, 2018 updated by: GlaxoSmithKline

Phase II, Observer-blind Follow-up Study to Assess reacto-and Immunogenicity of GSK Biologicals' Pneumococcal Conjugate Vaccine (GSK1024850A), When Given as Booster in Primed Children or as 2-dose Catch-up in Unprimed Children.

This is a booster study in 2 groups of healthy children less than 3 years old to measure the reactogenicity, safety and immunogenicity of GSK Biologicals' pneumococcal conjugate vaccine, when given as a booster or as a two-dose catch-up vaccination.

This protocol posting deals with objectives and outcome measures of the booster phase. The objectives and outcome measures of the primary phase are presented in a separate protocol posting (NCT number = NCT00338351).

What is the study measuring?

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Number of Subjects Reporting Grade 3 Symptoms (Solicited and Unsolicited)
Time Frame: Within 4 days after the administration of any study vaccine dose
Grade 3 symptoms are symptoms which prevent normal, everyday activities (e.g. in a young child such symptom would prevent attendance at school/ kindergarten/ a day-care center and would cause the parents/guardians to seek medical advice).
Within 4 days after the administration of any study vaccine dose

Secondary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Number of Subjects Reporting Solicited Local Symptoms
Time Frame: Within 4 days after the administration of any study vaccine dose
Solicited local symptoms assessed include pain, redness and swelling.
Within 4 days after the administration of any study vaccine dose
Number of Subjects Reporting Solicited General Symptoms
Time Frame: Within 4 days after the administration of any study vaccine dose

Solicited general symptoms assessed include drowsiness, fever, irritability and loss of appetite.

Fever was defined as rectal temperature ≥ 38 degrees Celsius.

Within 4 days after the administration of any study vaccine dose
Number of Subjects Reporting Unsolicited Adverse Events
Time Frame: Within 31 days after the administration of any study vaccine dose
An Adverse Event is 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.
Within 31 days after the administration of any study vaccine dose
Number of Subjects Reporting Serious Adverse Events During the Active Phase of the Study
Time Frame: Throughout the active phase of the study ( from the beginning of the booster phase up to 1 month after the second booster dose)
