This Study Will Evaluate the Immunogenicity, Reactogenicity and Safety of the Routine Infant Vaccines Pediarix®, Hiberix® and Prevenar 13® When Co-administered With GlaxoSmithKline (GSK) Biologicals' Liquid Human Rotavirus Vaccine (HRV) as Compared to GSK's Licensed Lyophilized Vaccine

Immunogenicity was assessed using Enzyme Linked Immunosorbent Assay (ELISA) in terms of seroprotection rates against diphtheria toxoid. A seroprotected subject is a subject whose antibody concentration is greater than or equal to (≥) the level defining clinical protection. The following seroprotection thresholds were applicable:anti-D antibody concentrations ≥ 0.1 International Units/milliliter (IU/mL), anti-T antibody concentrations ≥ 0.1 IU/mL.

Immunogenicity was assessed using ChemiLuminescence ImmunoAssay (CLIA) in terms of seroprotection rates against Hepatitis B. A seroprotected subject is a subject whose antibody concentration is ≥ the level defining clinical protection. The following seroprotection thresholds were applicable:anti-HB antibody concentrations ≥ 10 milli International Units/milliliter (mIU/mL).

Immunogenicity was assessed using virus micro-neutralization test in terms of seroprotection rates against polio virus types 1, 2 and 3. A seroprotected subject is a subject whose antibody concentration is ≥ the level defining clinical protection. The following seroprotection thresholds were applicable:anti-polio virus types 1, 2 and 3 types antibody titers ≥ 8 Estimated Dose 50% (ED50).

Antibody concentrations against PT, FHA and PRN were determined and expressed as Geometric Mean Concentrations (GMCs).The GMC calculations were performed by taking the anti-log of the mean of the log concentration transformations.

Antibody concentrations against pneumococcal serotypes (1, 3, 4, 5, 6A, 6B, 7F, 9V, 14, 18C, 19A, 19F, 23F) were determined and expressed as GMCs in micrograms per milliliter (µg/mL).The GMC calculations were performed by taking the anti-log of the mean of the log concentration transformations.

Immunogenicity was assessed in terms of seroprotection rates against PRP antibodies. A seroprotected subject is a subject whose antibody concentration is ≥ the level defining clinical protection. The following seroprotection thresholds were applicable:anti-PRP antibody concentrations ≥ 0.15 µg/mL.

Immunogenicity was assessed in terms of seroprotection rates against PRP antibodies. A seroprotected subject is a subject whose antibody concentration is ≥ the level defining clinical protection. The following seroprotection thresholds were applicable:anti-PRP antibody concentrations ≥ 1.0 µg/mL.

Seroresponse is defined as the percentage of subjects showing an antibody concentration above a threshold that leads to 95% seroresponse in the HRV lyophilized Group. The cut-offs used were as follows: anti-PT (18.566 IU/mL), anti-FHA (35.711 IU/mL) and anti-PRN (11.034 IU/mL).

Immunogenicity was assessed in terms of seropositivity against Rota virus IgA antibodies. The cut off used was ≥ 20 U/mL.

Immunogenicity was assessed in terms of seropositivity against Rota virus IgA antibodies. The cut off used was ≥ 90 U/mL.

Immunogenicity was assessed using ELISA technique in terms of seropositivity against PT, FHA and PRN antibodies. The cut-offs for antibodies were the Lower Limit Of Quantification (LLOQ) of the assays which were ≥ 2.693 IU/mL (anti-PT), ≥ 2.046 IU/mL (anti-FHA) and ≥ 2.187 IU/mL (anti-PRN).

The Limit of Quantification is the lowest analyte concentration that can be quantitatively detected with a stated accuracy and precision, and LLOQ is the lowest standard curve point obtained by extrapolation, that can still be used for quantification.

Immunogenicity was assessed using ELISA technique in terms of seropositivity against Pneumococcal serotypes (1, 3, 4, 5, 6A, 6B, 7F, 9V, 14, 18C, 19A, 19F, 23F) antibodies. The cut-off used was ≥ 0.35 µg/mL.

Antibody concentrations against diphtheria and tetanus were determined and expressed as GMCs. The GMC calculations were performed by taking the anti-log of the mean of the log concentration transformations.

Antibody concentrations against PRP were determined and expressed as GMCs. The GMC calculations were performed by taking the anti-log of the mean of the log concentration transformations.

Antibody concentrations against Hepatitis B were determined and expressed as GMCs. The GMC calculations were performed by taking the anti-log of the mean of the log concentration transformations.

Antibody concentrations against Poliovirus types 1, 2 and 3 were determined and expressed as Geometric Mean Titers (GMTs).

Assessed solicited general AEs were cough/runny nose; diarrhoea; fever measured by 3 routes which were oral, axillary and rectal, defined as temperature ≥ 38.0 degrees Celsius (°C); irritability; loss of appetite and vomiting. Any = any solicited general AE irrespective of its intensity grade and relationship to vaccination

Unsolicited AEs assessed include any AE reported in addition to those solicited during the clinical study. Also any 'solicited' symptom with onset outside the specified period of follow-up for solicited symptoms were reported as an unsolicited AE. Any= Any unsolicited AE irrespective of its intensity grade and relationship to vaccination.

SAEs assessed include any untoward medical occurrence that resulted in death, were life-threatening, required hospitalization or prolongation of existing hospitalization or resulted in disability/incapacity.
