Phase 3
Completed
Conditions
Pneumococcal Disease
Interventions
Registration Number
NCT05464420
Lead Sponsor
Merck Sharp & Dohme LLC
Brief Summary

This study will evaluate the safety, tolerability, and immunogenicity of a pneumococcal 21-valent conjugate vaccine (V116) in pneumococcal vaccine-naïve adults 18 to 49 years of age.

The primary study hypothesis is that all 3 lots of V116 are equivalent as assessed by the serotype-specific opsonophagocytic activity (OPA) Geometric Mean Titers (GMTs) at 30 days postvaccination for all serotypes included in V116.

Primary Outcome Measures
NameTimeMethod
Percentage of Participants With Solicited Systemic AEs Following Vaccination With Separate V116 LotsUp to 5 days

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 systemic AEs included headache, muscle aches/myalgia, tiredness/fatigue, and pyrexia. Per protocol, the PPSV23 treatment group was not included as it was not analyzed with the individual lots of V116.

Percentage of Participants With Solicited Systemic AEs Following Vaccination: Combined Lots of V116 or PPSV23Up to 5 days

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 systemic AEs included headache, muscle aches/myalgia, tiredness/fatigue, and pyrexia. Per the statistical analysis plan, no within group method of dispersion (MOD) were planned or calculated.

Percentage of Participants With Solicited Injection-site Adverse Events (AEs) Following Vaccination With Separate V116 LotsUp to 5 days

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. Per protocol, the PPSV23 treatment group was not included as it was not analyzed with the individual lots of V116.

Percentage of Participants With Solicited Injection-site AEs Following Vaccination: Combined Lots of V116 or PPSV23Up to 5 days

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. Per the statistical analysis plan, no within group method of dispersion (MOD) were planned or calculated.

Geometric Mean Titers (GMTs) of Serotype-specific Opsonophagocytic Activity (OPA) for All Serotypes in V116 Following Vaccination With Separate V116 LotsDay 30

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) were calculated using a constrained longitudinal data analysis (cLDA) model. Per protocol, within-group CIs were not calculated and the PPSV23 treatment group was not included as it was not analyzed with the individual lots of V116.

Percentage of Participants With Vaccine-related Serious Adverse Events (SAEs) Following Vaccination With Separate V116 LotsUp to 194 days

An SAE was any untoward medical occurrence that, at any dose, resulted in death, was life threatening, required inpatient hospitalization or prolonged existing hospitalization, resulted in persistent or significant disability/incapacity, was a congenital anomaly/birth defect, or was another important medical event. SAEs that were reported to be at least possibly related by the investigator to study vaccination were reported. Per protocol, the PPSV23 treatment group was not included as it was not analyzed with the individual lots of V116.

Percentage of Participants With Vaccine-related SAEs Following Vaccination: Combined Lots of V116 or PPSV23Up to 194 days

Serotype-specific IgG concentrations for all serotypes in V116 following vaccination were determined using pneumococcal electrochemiluminescence (PnECL). Serotype-specific pneumococcal IgG GMCs and GMC ratios with 95% confidence intervals were calculated using a cLDA model. Per protocol, within-group CIs were not calculated and the PPSV23 treatment group was not included as it was not analyzed with the individual lots of V116.
