Safety and Immunogenicity of V116 in Pneumococcal Vaccine-naïve Adults 50 Years of Age or Older (V116-010, STRIDE-10)

Phase 3
Active, not recruiting
Conditions
Pneumococcal Disease
Interventions
Biological: V116
Biological: PPSV23
Registration Number
NCT05569954
Lead Sponsor
Merck Sharp & Dohme LLC
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).

V116V116Participants will receive a single intramuscular (IM) vaccination of 0.5 mL of V116 on Day 1.

Primary Outcome Measures
NameTimeMethod
Percentage of Participants With Solicited Injection-Site Adverse Events (AEs)Up to 5 days postvaccination

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.

Percentage of Participants With Solicited Systemic AEsUp to 5 days postvaccination

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.

Percentage of Participants With Vaccine-Related Serious Adverse Events (SAEs)Up to 6 months postvaccination

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.

Serotype-Specific Opsonophagocytic (OPA) Geometric Mean Titers (GMTs) for All Serotypes in V116Day 30 postvaccination

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.

Percentage of Participants With ≥4-fold Rise From Baseline in Serotype-Specific OPAs for Serotypes Unique to V116Baseline (Day 1) and Day 30 postvaccination

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.

Secondary Outcome Measures
NameTimeMethod
Percentage of Participants With ≥4-fold Rise From Baseline in Serotype-Specific Cross-Reactive OPAsBaseline (Day 1) and Day 30 postvaccination

OPA induced by serotypes 6A and 15C in V116 but cross-reactive to serotypes 6C and 15B, respectively, were measured. The percentage of participants with ≥4-fold rise from baseline in serotype-specific cross-reactive OPAs was determined. Point estimate, 95% CI, and p-value are based on the Clopper-Pearson method. Per protocol, this outcome measure was not planned or analyzed in the PPSV23 study arm.

Serotype-Specific Geometric Mean Fold Rise (GMFR) of OPA GMTs for All Serotypes in V116Baseline (Day 1) and Day 30 postvaccination

The GMFR from baseline in serotype-specific OPA GMTs for all serotypes in V116 was determined using MOPA. The within-group 95% CIs are obtained by exponentiating the CIs of the mean of the natural log values based on the t-distribution.

Serotype-Specific Immunoglobulin G (IgG) Geometric Mean Concentrations (GMCs) for All Serotypes in V116Day 30 postvaccination

The GMCs for serotype-specific IgG antibodies for all serotypes in V116 were determined using pneumococcal electrochemiluminescence (PnECL). The GMC ratio estimation and 95% CI were calculated using a cLDA method. Per protocol, within-group CIs, or any other method of dispersion were not planned or calculated.

Serotype-Specific GMFR of IgG GMCs for All Serotypes in V116Baseline (Day 1) and Day 30 postvaccination

The GMFR from baseline in GMCs for serotype-specific IgG antibodies for all serotypes in V116 was determined using PnECL. The within-group 95% CIs are obtained by exponentiating the CIs of the mean of the natural log values based on the t-distribution.

Percentage of Participants With ≥4-Fold Rise From Baseline in Serotype-Specific OPA GMTs for All Serotypes in V116Baseline (Day 1) and Day 30 postvaccination

The percentage of participants with ≥4-fold rise from baseline in serotype-specific OPA GMTs for all serotypes in V116 was determined with MOPA. The within-group CIs were calculated based on the Clopper-Pearson method.

Percentage of Participants With ≥4-Fold Rise From Baseline in Serotype-Specific IgG GMCs for All Serotypes in V116Baseline (Day 1) and Day 30 postvaccination

The percentage of participants with ≥4-fold rise from baseline in serotype-specific IgG GMCs for all serotypes in V116 was determined using PnECL. The within-group CIs were calculated based on the Clopper-Pearson method.
