Study Comparing 13-valent Pneumococcal Conjugate Vaccine With 7-valent Pneumococcal Conjugate Vaccine

The purpose of this study is to evaluate the safety, tolerability, and immunogenicity of the 13-valent pneumococcal vaccine (13vPnC) compare to the 7-valent pneumococcal vaccine (7vPnC) and to compare the immune response to concomitant vaccines administered with 13vPnC and 7vPnC.

Treatment and study plan

13 valent Pneumococcal Conjugate Vaccine

Biological

1 single 0.5 mL dose together with a concomitant dose of Pediarix and ActHIB at the 2-, 4-, and 6-month visits and ProQuad, PedvaxHIB, and VAQTA at the 12-15 month visit.

7vPnc pneumococcal conjugate vaccine

Biological

1 single 0.5 mL dose together with a concomitant dose of Pediarix and ActHIB at the 2-, 4-, and 6-month visits and ProQuad, PedvaxHIB, and VAQTA at the 12-15 month visit.

Primary outcomes

  1. Percentage of Participants Achieving Antibody Level ≥0.35 μg/mL in 13vPnC Group Relative to 7vPnC Group After the 3-Dose Infant Series

    Time frame: One month after the 3-dose infant series (7 months of age)

    Percentages of Participants achieving World Health Organization (WHO) predefined antibody threshold ≥0.35 μg/mL along with the corresponding 95% CI for the 7 common pneumococcal serotypes (serotypes 4, 6B, 9V, 14, 18C, 19F, and 23F) and 6 additional pneumococcal serotypes specific to 13vPnC (serotypes 1, 3, 5, 6A, 7F, and 19A) are presented.

  2. Geometric Mean Antibody Concentration in 13vPnC Group Relative to 7vPnC Group 1 Month After the Toddler Dose

    Time frame: 1 Month After the Toddler Dose

    Antibody concentration/geometric mean concentration as measured by enzyme-linked immunosorbent assay (ELISA) for 7 common pneumococcal serotypes (serotypes 4, 6B, 9V, 14, 18C, 19F, and 23F) and 6 additional pneumococcal serotypes specific to 13vPnC (Serotypes 1, 3, 5, 6A, 7F, and 19A) are presented.

  3. Percentage of Participants Achieving Predefined Antibody Levels for Haemophilus Influenzae Type b, Diphtheria Toxoid, and Pertussis Antigens in 13vPnC Group Relative to 7vPnC Group After the Infant Series

    Time frame: One Month After the Infant Series (7 months of age)

    Predefined Antibody Levels for Haemophilus Influenzae Type b ([Hib] 0.15 µg/mL or 1.0 µg/mL), Diphtheria Toxoid (0.1 International Units [IU]/mL), and Pertussis antigens (Pertussis filamentous hemagglutinin [FHA] 40.5 Elisa Units [EU]/mL, Pertussis toxoid [PT] 16.5 EU/mL, Pertussis pertactin [PRN] 26 EU/mL).

  4. Percentage of Participants Reporting Pre-specified Systemic Events

    Time frame: Within 7 days after each dose

    Systemic events (any fever [Fv] ≥ 38 degrees Celsius [C], decreased (decr.) appetite, irritability, increased (incr.) sleep, decreased sleep, and hives [urticaria], use of antipyretic medication [med] to treat or prevent symptoms [sx]) were reported using an electronic diary. Participants may be represented in more than 1 category.

  5. Percentage of Participants Reporting Pre-specified Local Reactions

    Time frame: Within 7 days after each dose

    Local reactions were reported using an electronic diary. Tenderness was scaled as Any (tenderness present); Significant ([Sig.], present and interfered with limb movement). Redness and swelling were scaled as Any (redness or swelling present); Mild (0.5 centimeters [cm] to 2.0 cm); Moderate ([Mod.], 2.5 to 7.0 cm); Severe ([Sev.], > 7.0 cm). Participants may have been represented in more than 1 category.

Secondary outcomes

  1. Percentage of Participants Achieving Predefined Antibody Levels for Concomitant Vaccine Antigens Induced by Measles, Mumps, Rubella, Varicella (MMR-V) and Haemophilus Influenzae Type b (Hib)

    Time frame: One month after toddler dose (13 to 16 months of age)

  2. Geometric Mean Antibody Concentration of Hib PRP in 13vPnC Group Relative to 7vPnC Group After the Toddler Dose

    Time frame: one month after the toddler dose

  3. Geometric Mean Antibody Concentration of Measles, Mumps, and Varicella ELISA in 13vPnC Group Relative to 7vPnC Group After the Toddler Dose

    Time frame: one month after the toddler dose

    Normalization was performed for unit of measure "index value" as Index Value of 1.00 = 10 mIU/mL.

  4. Geometric Mean Antibody Concentration of Rubella in 13vPnC Group Relative to 7vPnC Group After the Toddler Dose

    Time frame: one month after the toddler dose

  5. Percentage of Participants Achieving Functional Antibody Titer ≥1:8 as Measured by Opsonophagocytic Activity Assay (OPA) in 13vPnC Group Relative to 7vPnC Group the 3-Dose Infant Series and the Toddler Dose

    Time frame: One month after infant series and one month after toddler dose

    Percentage of participants achieving functional antibody titer ≥1:8 as measured by opsonophagocytic activity assay (OPA) along with the corresponding 95% CI for the 7 common pneumococcal serotypes (serotypes 4, 6B, 9V, 14, 18C, 19F, and 23F) and 6 additional pneumococcal serotypes specific to 13vPnC (serotypes 1, 3, 5, 6A, 7F, and 19A) are presented.

  6. Geometric Mean Titer (GMT) as Measured by Opsonophagocytic Activity Assay (OPA) in 13vPnC Group Relative to 7vPnC Group After the 3-Dose Infant Series and the Toddler Dose

    Time frame: one month after the infant series and the toddler dose

    Geometric mean titer (GMT) as measured by opsonophagocytic activity assay (OPA) for 7 common pneumococcal serotypes (serotypes 4, 6B, 9V, 14, 18C, 19F, and 23F) and 6 additional pneumococcal serotypes specific to 13vPnC (Serotypes 1, 3, 5, 6A, 7F, and 19A) are presented.
