NCT05569954

Brief Summary

This is a phase 3, randomized, double-blind, active comparator-controlled study of the safety, tolerability, and immunogenicity of V116 in pneumococcal vaccine-naïve adults 50 years of age and older. The polyvalent (23-valent) pneumococcal vaccine, PPSV23, is the active comparator. In addition to studying safety/tolerability, it is hypothesized that, at 30 days postvaccination, the immunogenicity of V116 is noninferior to PPSV23 for the 12 common serotypes in V116 and PPSV23, and that V116 is superior to PPSV23 for the 9 serotypes unique to V116. It is also hypothesized that V116 is superior to PPSV23 in the percentage of participants with ≥4-fold rise from baseline in unique V116 serotypes, as measured by serotype-specific opsonophagocytic activity (OPA) geometric mean titers (GMTs).

Outcome Measures

Primary Outcomes (5)

  • Percentage of Participants With Solicited Injection-Site Adverse Events (AEs)

    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 injection-site AEs consisted of pain/tenderness, redness/erythema, and swelling. 95% confidence intervals (CIs) for between-group differences are provided using the Miettinen \& Nurminen method.

    Up to 5 days postvaccination

  • Percentage of Participants With Solicited Systemic AEs

    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 consist of the following: fatigue (tiredness), headache, myalgia (muscle aches), and pyrexia (maximum temperature ≥ 100.4 °F/38.0 °C). 95% confidence intervals (CIs) for between-group differences are provided using the Miettinen \& Nurminen method.

    Up to 5 days postvaccination

  • Percentage of Participants With Vaccine-Related Serious Adverse Events (SAEs)

    An SAE is any untoward medical occurrence that 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 an other important medical event. SAEs that were reported to be at least possibly related by the investigator to study vaccination are summarized. 95% confidence intervals (CIs) for between-group differences are provided using the Miettinen \& Nurminen method.

    Up to 6 months postvaccination

  • Serotype-Specific Opsonophagocytic (OPA) Geometric Mean Titers (GMTs) for All Serotypes in V116

    Serotype-specific OPA titers for all serotypes in V116 following vaccination were determined using multiplex opsonophagocytic assay (MOPA). Serotype-specific OPA GMTs and GMT ratios with 95% confidence intervals (CIs), and they hypothesis test (1-sided p-value), were calculated using a constrained longitudinal data analysis (cLDA) model. Per protocol, within-group CIs, or any other method of dispersion were not planned or calculated.

    Day 30 postvaccination

  • Percentage of Participants With ≥4-fold Rise From Baseline in Serotype-Specific OPAs for Serotypes Unique to V116

    The percentage of participants with ≥4-fold rise from baseline in serotype-specific OPAs for the unique pneumococcal serotypes contained in V116 was determined. The 9 unique pneumococcal serotypes in V116 are as follows: 6A, 15A, 15C, 16F, 23A, 23B, 24F, 31, and 35B. Per protocol, within-group CIs, or any other method of dispersion were not planned or calculated.

    Baseline (Day 1) and Day 30 postvaccination

Secondary Outcomes (6)

  • Percentage of Participants With ≥4-fold Rise From Baseline in Serotype-Specific Cross-Reactive OPAs

    Baseline (Day 1) and Day 30 postvaccination

  • Serotype-Specific Geometric Mean Fold Rise (GMFR) of OPA GMTs for All Serotypes in V116

    Baseline (Day 1) and Day 30 postvaccination

  • Serotype-Specific Immunoglobulin G (IgG) Geometric Mean Concentrations (GMCs) for All Serotypes in V116

    Day 30 postvaccination

  • Serotype-Specific GMFR of IgG GMCs for All Serotypes in V116

    Baseline (Day 1) and Day 30 postvaccination
