Clinical Trial Summary

This study will assess the safety, reactogenicity and immunogenicity of different formulations of GSK Biologicals' pneumococcal vaccine 2189242A when administered alone or in combination with the 10-valent pneumococcal conjugate vaccine (GSK1024850A vaccine) as a 2-dose primary vaccination course followed by a booster dose in healthy children aged 12-23 months at the time of first vaccination. Considering that febrile reactions are frequently observed following pneumococcal vaccination, usually co-administered with other routine paediatric vaccines, the primary study objective will focus on evaluating the increase in grade 3 fever (i.e. rectal temperature >40.0°C).

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Number of Subjects With Fever > 40.0°C (Rectal Temperature)	The number of subjects with rectal temperature higher (>) than 40.0 degrees Celsius (°C) is reported.	Within 7 days (Day 0-Day 6) following at least one dose of the primary vaccination
Secondary	Number of Subjects Reporting Any and Grade 3 Solicited Local Symptoms	Solicited local symptoms assessed include pain, redness and swelling. Grade 3 pain was defined as crying when limb was moved/spontaneously painful. Grade 3 swelling/redness was defined as swelling/redness larger than (>) 30 millimeters (mm). "Any" is defined as incidence of the specified symptom regardless of intensity.	During the 7-day (Days 0-6) post-vaccination period following each dose (Dose 1, Dose 2 and Booster dose)
Secondary	Number of Subjects Reporting Any, Grade 3 and Related Solicited General Symptoms	Solicited general symptoms assessed include drowsiness, fever (defined as rectally temperature = 38.0°C), irritability, and loss of appetite. Grade 3 drowsiness = drowsiness which prevented normal everyday activities. Grade 3 fever was defined as fever (rectally temperature) above (>) 40.0 degree Celsius (°C). Grade 3 irritability = crying that could not be comforted/preventing normal activity. Grade 3 loss of appetite = not eating at all. "Any" is defined as incidence of the specified symptom regardless of intensity or relationship to study vaccination.	During the 7-day (Days 0-6) post-vaccination period following each dose (Dose 1, Dose 2, Booster dose)
Secondary	Number of Subjects With Unsolicited Adverse Events (AEs)	An AE 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. "Any" is defined an incidence of an unsolicited AE regardless of intensity or relationship to study vaccination.	During the 31-day (Days 0-30) follow-up period after each primary dose
Secondary	Number of Subjects With Unsolicited Adverse Events (AEs)	An AE 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. "Any" is defined an incidence of an unsolicited AE regardless of intensity or relationship to study vaccination.	During the 31-day (Days 0-30) follow-up period after the booster dose
Secondary	Number of Subjects With Serious Adverse Events (SAEs)	SAEs assessed include medical occurrences that result in death, are life-threatening, require hospitalization or prolongation of hospitalization or result in disability/incapacity.	During the entire study period starting at the administration of the first vaccine dose up to study end (from Day 0 up to Month 7)
Secondary	Anti-pneumococcal dPly and PhtD Proteins Antibody Concentrations	Seropositivity status, defined as anti-pneumococcal dPly antibody concentrations = 599 Luminex Units per milliliter (LU/mL) and anti-pneumococcal PhtD antibody concentrations = 391 LU/mL.	One month post-dose 2 (Month 3), prior to the booster dose (Month 6) and one month post-booster (Month 7)
Secondary	Anti-pneumococcal Serotypes and Cross-reactive Serotypes Antibody Concentrations	Seropositivity status, defined as anti-pneumococcal serotypes 1, 4, 5, 6B, 7F, 9V, 14, 18C, 19F and 23F and cross-reactive serotype 6A and 19 antibody concentrations = 0.05 microgram per milliliter (µg/mL).	One month post-dose 2 (Month 3), prior to the booster dose (Month 6) and one month post-booster (Month 7)
Secondary	Opsonophagocytic Activity (OPA) Titers Against Pneumococcal Serotypes and Cross-reactive Serotypes	Seropositivity status, defined as Opsonophagocytic activity against pneumococcal serotypes 1, 4, 5, 6B, 7F, 9V, 14, 18C, 19F and 23F and cross-reactive serotypes 6A and 19A = 8.

Secondary	Level of Anti-dPly Antibodies Inhibiting Ply Haemolysis Activity	Inhibition of haemolysis activity of pneumolysin (Ply) by anti-dPly antibodies was measured in vitro by mean of a haemolytic assay. The haemolysis activity could be followed by measuring the level of haemoglobin released. Anti-dPly titers (for inhibition of haemolytic activity) = 140.
