A Study to Evaluate the Safety, Tolerability, Immunogenicity, and Lot Consistency of V116 in Adults 18 to 49 Years of Age (V116-004, STRIDE-4)

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.

Time frame: Day 30

Population: Per protocol, all randomized participants who were vaccinated with V116 and were without deviations from the protocol that may substantially affect the results of the immunogenicity endpoint and who had sufficient data to perform the analysis. Deviations include, but are not limited to the following: randomized but not vaccinated, blood drawn out of time window, prohibited concomitant medication or vaccination.

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.

Time frame: Up to 5 days

Population: Per protocol, all randomized participants who received one of three lots of V116 were analyzed according to the vaccination they received. One participant randomized to the V116 Lot 1 incorrectly received V116 Lot 3 and one participant randomized into the V116 Lot 2 group incorrectly received V116 Lot 1, and one participant randomized to the V116 Lot 2 arm incorrectly received PPSV23.

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.

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.

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 the statistical analysis plan, no within group MOD were planned or calculated.

Time frame: Up to 194 days

Population: All randomized participants who received study vaccination were analyzed according to the vaccination they received. One participant randomized into the V116 Lot 2 group incorrectly received PPSV23.

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.

Population: Per protocol, all randomized participants who were vaccinated with V116 and were without deviations from the protocol that may substantially affect the results of the immunogenicity endpoint and who had sufficient data to perform the analysis. Deviations include, but are not limited to the following: randomized but not vaccinated, blood drawn out of time window, prohibited concomitant medication or vaccination.

Serotype-specific OPA GMFR for all serotypes in V116 following vaccination were determined using MOPA. The GMFR of each pneumococcal serotype was calculated as Day 30 GMT/Day 1 GMT. The 95% CIs were calculated based on based on the t-distribution. Per protocol, the PPSV23 treatment group was not included as it was not analyzed with the individual lots of V116.
