A Clinical Study of the V116 Vaccine for Children and Teenagers (V116-013)

The purpose of this study is to evaluate the safety, tolerability, and immunogenicity of V116 compared to PPSV23 in children and teenagers 2 through 17 years of age, who had completed routine pneumococcal vaccine as infants/toddlers. Researchers want to learn if V116 is as good as, or is better than the PPSV23 vaccine in terms of the antibody immune response. V116 and PPSV23 will be studied in children and teenagers who have a higher risk of getting pneumococcal disease (PD).

Primary outcomes

  1. Percentage of Participants With Solicited Injection-site Adverse Events (AEs)

    Time frame: Up to 5 days postvaccination

    An AE was any untoward medical occurrence in a clinical study participant, temporally associated with the use of study intervention, whether or not considered related to the study intervention. Solicited injection-site AEs included pain/tenderness, redness/erythema, and swelling.

  2. Percentage of Participants With Solicited Systemic AEs

    Time frame: Up to 5 days post vaccination

    An AE is any untoward medical occurrence in a clinical study participant, temporally associated with the use of study intervention, whether or not considered related to the study intervention. Solicited systemic AEs included muscle aches all over the body (myalgia), headache, tiredness (fatigue), hives or welts (urticaria), irritability, joint pain (arthralgia), drowsiness (somnolence), feeling sick (malaise), and fever (pyrexia).

  3. Percentage of Participants With Vaccine-related Serious Adverse Events (SAEs)

    Time frame: Up to approximately 6 months

    A vaccine-related SAE is any untoward medical occurrence that, at any dose, results in death, is life threatening, requires inpatient hospitalization or prolongs existing hospitalization, results in persistent or significant disability/incapacity, is a congenital anomaly/birth defect, or is another important medical event.

  4. Geometric Mean Titer of Serotype-specific Opsonophagocytic Activity (OPA) Responses

    Time frame: 30 days postvaccination

    Opsonophagocytic activity (OPA) for the serotypes in V116 will be determined using a multiplexed opsonophagocytic assay (MOPA). Serotype-specific OPA GMTs and GMT ratios with 95% confidence intervals (CIs) were calculated using a constrained longitudinal data analysis (cLDA) model. The 12 common pneumococcal serotypes in both V116 and PPSV23 were as follows: 3, 7F, 8, 9N, 10A, 11A, 12F, 17F, 19A, 20A, 22F, and 33F. The 9 unique pneumococcal serotypes in V116 were as follows: 6A, 15A, 15C, 16F, 23A, 23B, 24F, 31, and 35B.

Secondary outcomes

  1. Geometric Mean Concentrations (GMCs) of Serotype-specific Immunoglobulin G (IgG) After Vaccination

    Time frame: 30 days postvaccination

    The GMCs for serotype-specific IgG antibodies will be determined using pneumococcal electrochemiluminescence (PnECL). Serotype-specific IgGs and GMC ratios with 95% CIs were calculated using a cLDA model. The 12 common pneumococcal serotypes in both V116 and PPSV23 were as follows: 3, 7F, 8, 9N, 10A, 11A, 12F, 17F, 19A, 20A, 22F, and 33F. The 9 unique pneumococcal serotypes in V116 were as follows: 6A, 15A, 15C, 16F, 23A, 23B, 24F, 31, and 35B.

  2. Geometric Mean Fold Rise (GMFR) From Baseline in Serotype-specific OPA GMTs

    Time frame: Baseline (Day 1) and 30 days postvaccination

    The GMFR from baseline in serotype-specific OPA GMTs was determined using MOPA at baseline and 30 days postvaccination and derived from a cLDA model. The GMFR (Day 30 GMT/Day 1 GMT) from baseline (Day 1) to Day 30 of each pneumococcal OPA serotype was calculated. The 12 common pneumococcal serotypes in both V116 and PPSV23 were as follows: 3, 7F, 8, 9N, 10A, 11A, 12F, 17F, 19A, 20A, 22F, and 33F. The 9 unique pneumococcal serotypes in V116 were as follows: 6A, 15A, 15C, 16F, 23A, 23B, 24F, 31, and 35B.

  3. Percentage of Participants With ≥4-fold Rise From Baseline in Serotype-specific OPAs GMTs

    Time frame: Baseline (Day 1) and Day 30 postvaccination

    The percentage of participants with ≥4-fold rise from baseline (Day 1) to Day 30 in GMTs of each pneumococcal serotype was calculated. Titer levels were determined by the MOPA and derived from a cLDA model. The 12 common pneumococcal serotypes in both V116 and PPSV23 were as follows: 3, 7F, 8, 9N, 10A, 11A, 12F, 17F, 19A, 20A, 22F, and 33F. The 9 unique pneumococcal serotypes in V116 were as follows: 6A, 15A, 15C, 16F, 23A, 23B, 24F, 31, and 35B.

  4. GMFR From Baseline in Serotype-specific IgG GMCs

    Time frame: Baseline (Day 1) and Day 30 postvaccination

The GMFR (Day 30 GMT/Day 1 GMT) from baseline (Day 1) to Day 30 of each pneumococcal IgG serotype was calculated. The 12 common pneumococcal serotypes in both V116 and PPSV23 were as follows: 3, 7F, 8, 9N, 10A, 11A, 12F, 17F, 19A, 20A, 22F, and 33F.
