13-valent Pneumococcal Conjugate Vaccine
Biological13-valent pneumococcal conjugate vaccine administered at 2-, 4-, 6-, and 12 months of age.
NCT Number: NCT00475033
The purpose of this study will be to evaluate the safety, tolerability and immunogenicity of 13-valent pneumococcal conjugate vaccine in healthy infants given with routine pediatric vaccinations in Canada. Immune responses induced by the infant series (NeisVac-C® and Pentacel®)and toddler dose(NeisVac-C®)of routine pediatric vaccines when administered with 13-valent pneumococcal conjugate vaccine will be studied for noninferiority to the immune responses when administered with 7-valent pneumococcal conjugate vaccine. Safety profile and immunogenicity of 13-valent pneumococcal conjugate vaccine will also be evaluated.

13-valent pneumococcal conjugate vaccine administered at 2-, 4-, 6-, and 12 months of age.
7-valent pneumococcal conjugate vaccine administered at 2-, 4-, 6-, and 12 months of age.
Time frame: 1 month after 2 doses of NeisVac-C® in the infant series (7 months of age)
Percentage of subjects achieving predefined antibody threshold ≥1:8 along with the corresponding 95 percent (%) confidence interval (CI) for concomitant antigen meningococcal C SBA are presented. Non-inferiority was declared if the lower limit of the 2-sided 95% CI for the difference between the 2 treatment groups > -10%.
Time frame: 1 month after 2 doses of NeisVac-C® in the infant series (7 months of age)
Antibody geometric mean titer of meningococcal C antigen are presented. GMT and corresponding 2-sided 95% CI were constructed by back transformation of the CI for the mean of the logarithmically transformed assay results computed using the Student t distribution. In addition, the 2-sided 95% confidence interval on the ratio of the geometric means for 13vPnC relative to 7vPnC was constructed by back transformation of the Student t distribution for the mean difference of the measures on the logarithmic scale.
Time frame: 1 month after the 3-dose infant series (7 months of age)
Percentage of subjects achieving predefined antibody threshold ≥5 enzyme-linked immunosorbent assay (ELISA) units per mL (EU/mL) along with the corresponding 95 % CI for concomitant antigens pertussis (pertussis toxoid [PT], filamentous hemagglutinin [FHA], and pertactin [PRN]) and ≥ 2.2 EU/mL fimbrial agglutinogens (FIM) are presented. Non-inferiority was declared if the lower limit of the 2-sided 95% CI for the difference between the 2 treatment groups > -10%.
Time frame: 1 month after the 3-dose Infant Series (7 months of age)
Antibody geometric mean concentration of pertussis antigens (PT, FHA, PRN, and FIM) as measured by EU/mL are presented. GMC and corresponding 2-sided 95% CI were constructed by back transformation of the CI for the mean of the logarithmically transformed assay results computed using the Student t distribution.

Time frame: 1 month after the 3-dose infant series (7 months of age)
Percentage of subjects achieving predefined antibody threshold ≥0.15 μg/mL along with the corresponding 95 percent (%) confidence interval (CI) for concomitant antigen PRP in Hib are presented.

Time frame: 1 month after the 3-dose infant series (7 months of age)
Antibody geometric mean concentration of PRP in Hib as measured by µg/mL are presented. GMC and corresponding 2-sided 95% CI were constructed by back transformation of the CI for the mean of the logarithmically transformed assay results computed using the Student t distribution. In addition, the 2-sided 95% confidence interval on the ratio of the GMCs for 13vPnC relative to 7vPnC was constructed by back transformation of the Student t distribution for the mean difference of the measures on the logarithmic scale.
Time frame: 1 month after the toddler dose of NeisVac-C® (13 months of age)
Percentage of subjects achieving predefined antibody threshold ≥1:8 along with the corresponding 95% CI for concomitant antigen meningococcal C SBA are presented. Non-inferiority was declared if the lower limit of the 2-sided 95% CI for the difference between the 2 treatment groups > -10%.
Time frame: 1 month after the toddler dose (13 months of age)

In addition, the 2-sided 95% confidence interval on the ratio of the GMs for 13vPnC relative to 7vPnC was constructed by back transformation of the Student t distribution for the mean difference of the measures on the logarithmic scale.
Time frame: 1 month after the 3-dose infant series (7 months of age)
Percentage of subjects achieving predefined antibody threshold ≥1.0 μg/mL along with the corresponding 95% CI for concomitant antigen PRP in Hib are presented. Non-inferiority was declared if the lower limit of the 2-sided 95% CI for the difference between the 2 treatment groups > -10%.
