A Safety And Immunogenicity Study Of A 13-valent Pneumococcal Conjugate Vaccine In Japanese Subjects Aged 6 To 64 Years.

Local reactions were recorded using an electronic daily diary. Local reactions included redness, swelling and pain at injection site. Redness and swelling were graded as mild (0.5 to 2.0 centimeter [cm]), moderate (greater than [>] 2.0 to 7.0 cm) and severe (>7.0 cm) for participants aged 6 to <12 years, and as mild (2.5 to 5.0 cm), moderate (>5.0 to 10.0 cm) and, severe (>10.0 cm) for participants aged 12 to <18 years. Pain at injection site was graded as mild (did not interfere with activity), moderate (interfered with activity), and severe (prevented daily activity).

Local reactions were recorded using an electronic daily diary. Local reactions included redness, swelling and pain at injection site. Redness and swelling were graded as mild (2.5 to 5.0 cm), moderate (>5.0 to 10.0 cm) and, severe (>10.0 cm). Pain at injection site was graded as mild (did not interfere with activity), moderate (interfered with activity), and severe (prevented daily activity).

Systemic events included fever, vomiting, diarrhea, headache, fatigue, muscle and joint pain, and were recorded by using an e-diary. Use of antipyretic or pain medication was also collected by using an e-diary. Fever was graded as 37.5 to 38.4 degree Celsius (C), 38.5 to 38.9 degree C, 39.0 to 40.0 degree C and >40.0 degree C. Vomiting was graded as mild (1-2 times in 24 hours), moderate (>2 times in 24 hours) and severe (required intravenous hydration). Diarrhea was graded as mild (2-3 loose stools in 24 hours), moderate (4-5 loose stools in 24 hours) and severe (greater than or equals to [>=] 6 loose stools in 24 hours). Headache, fatigue, muscle pain and joint pain were graded as mild (no interference with activity), moderate (some interference with activity) and severe (significant, prevented daily activity).

Diarrhea was graded as mild (2-3 loose stools in 24 hours), moderate (4-5 loose stools in 24 hours) and severe (>=6 loose stools in 24 hours). Headache, fatigue, muscle pain and joint pain were graded as mild (no interference with activity), moderate (some interference with activity) and severe (significant, prevented daily activity).

An AE was any untoward medical occurrence in a participant who received study vaccine without regard to possibility of causal relationship. An SAE is any untoward medical occurrence at any dose that results in death; is life-threatening (immediate risk of death); requires inpatient hospitalization or prolongation of existing hospitalization; results in persistent or significant disability/incapacity (substantial disruption of the ability to conduct normal life functions); results in congenital anomaly/birth defect.

Antibody-mediated serum OPA against each of the 13 pneumococcal serotypes (1, 3, 4, 5, 6A, 6B, 7F, 9V, 14, 18C, 19A, 19F, and 23F) was measured centrally using a quantitative functional microcolony OPA (mcOPA) assay. Results were expressed as OPA titers. OPA titers were logarithmically transformed for analysis; geometric means calculated and expressed as geometric mean titers (GMTs). Two (2)-sided 95% CIs were constructed by back transformation of the CI for the mean of the logarithmically transformed assay results computed based on the Student t distribution. OPA titer was expressed as reciprocal of highest serum dilution.

OPA GMFRs were calculated along with corresponding 2-sided 95% CIs for pneumococcal serotypes 1, 3, 4, 5, 6A, 6B, 7F, 9V, 14, 18C, 19A, 19F, and 23F. GMFRs were computed as the fold rise in titer value at 1 month after vaccination compared to baseline (pre-vaccination). The CIs for GMFRs were back transformations of a CI based on the Student t distribution for the mean difference of the log-transformed assay results before vaccination and 1 month after vaccination.

Pneumococcal IgG antibody against each of the 13 pneumococcal serotypes (1, 3, 4, 5, 6A, 6B, 7F, 9V, 14, 18C, 19A, 19F, and 23F) was measured centrally using direct binding Luminex assay. Results were expressed as IgG concentrations. IgG concentrations were logarithmically transformed for analysis; geometric means calculated and expressed as GMCs. Two (2)-sided 95% CIs were constructed by back transformation of the CI for the mean of the logarithmically transformed assay results computed based on the Student t distribution.

GMFRs were computed as the fold rise in concentrations at 1 month after vaccination compared to baseline (pre-vaccination).
