A Study to Evaluate the Safety, Tolerability, and Immunogenicity of V116 in Pneumococcal Vaccine-experienced Adults (V116-006, STRIDE-6)

Phase 3
Completed
Conditions
Pneumonia, Pneumococcal
Interventions
Registration Number
NCT05420961
Lead Sponsor
Merck Sharp & Dohme LLC
Brief Summary

This a study of V116 in adults ≥50 years of age who previously received a pneumococcal vaccination ≥1 year before enrollment. The primary objectives of this study are to evaluate the safety, tolerability, and immunogenicity of V116.

Detailed Description

Participants will be randomized to 1 of 3 cohorts depending upon prior vaccinations. Prior vaccinations by cohort include: PPSV23 (pneumococcal vaccine, polyvalent \[23-valent\], PNEUMOVAX™23) for Cohort 1; PCV13 (pneumococcal 13-valent conjugate vaccine; PREVNAR 13™) for Cohort 2; PCV15 (pneumococcal 15-valent conjugate vaccine; VAXNEUVANCE™), PCV20 (pneumococcal 20-valent conjugate vaccine; PREVNAR 20™), PCV13+PPSV23, PCV15+PPSV23, or PPSV23+PCV13 for Cohort 3.

Primary Outcome Measures
NameTimeMethod
Percentage of Participants With Solicited Systemic AEsUp to 5 days post-vaccination

An AE is any untoward medical occurrence in a patient or clinical study participant, temporally associated with the use of study intervention, whether or not considered related to the study intervention. Following any of the injections with either V116, PCV15, or PPSV23, the percentage of participants with solicited systemic AEs was assessed. The solicited systemic AEs assessed were fatigue, headache, myalgia, and pyrexia.

Geometric Mean Titer (GMT) of Serotype-specific Opsonophagocytic Activity (OPA)30 Days post-vaccination

OPA for the serotypes contained in V116 were determined using a multiplex opsonophagocytic assay (MOPA). GMT is defined as geometric mean titer (1/dil). Serotype-specific OPA GMTs with 95% confidence intervals are presented.

Percentage of Participants With Solicited Injection-site Adverse Events (AEs)Up to 5 days post-vaccination

An adverse event (AE) is any untoward medical occurrence in a patient or clinical study participant, temporally associated with the use of study intervention, whether or not considered related to the study intervention. Following any injection with either V116, PCV15, or PPSV23 the percentage of participants with solicited injection-site AEs was assessed. The solicited injection-site AEs assessed were erythema, pain, and swelling.

Percentage of Participants With Vaccine-related Serious Adverse Events (SAEs)Up to ~180 days

A serious adverse event (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. The percentage of participants with one or more SAE that were assessed by the investigator to be at least possibly related to the study vaccination are presented.

Secondary Outcome Measures
NameTimeMethod
Geometric Mean Concentration (GMC) of Serotype-specific Immunoglobulin G (IgG)30 Days post-vaccination

The geometric mean concentration (GMC) of serotype-specific immunoglobulin G (IgG) for the serotypes contained in V116 was determined using a pneumococcal electrochemiluminescence (PnECL) assay. Serotype-specific pneumococcal IgG GMCs with 95% confidence intervals are presented.

Geometric Mean Fold Rise of Serotype-specific IgGDay 1 (Baseline) and 30 days post-vaccination

Activity for the serotypes contained in V116 was determined using a PnECL assay. Geometric mean fold rise (GMFR) is defined as the geometric mean of the ratio of concentration at Day 30 after vaccination divided by concentration at baseline. The GMFRs IgG responses from baseline to 30 days post-vaccination with 95% confidence intervals are presented.

Geometric Mean Fold Rise in Serotype-specific Opsonophagocytic Activity (OPA)Day 1 (Baseline) and 30 days post-vaccination

Activity for the serotypes contained in V116 was determined using a multiplex opsonophagocytic assay (MOPA). Geometric mean fold rise (GMFR) is defined as the geometric mean of the ratio of concentration at Day 30 after vaccination divided by concentration at baseline. The GMFRs in OPA responses from baseline to 30 days post-vaccination with 95% confidence intervals are presented.

Percentage of Participants Who Achieve a ≥4-fold Increase in Serotype-specific OPA ResponsesDay 1 (Baseline) and 30 days post-vaccination

Activity for the serotypes contained in V116 was determined using a MOPA. The percentage of participants with a ≥4-fold rise from baseline to at 30 days post-vaccination for OPA responses with 95% confidence intervals are presented.

Percentage of Participants Who Achieve a ≥4-fold Increase in Serotype-specific IgG ResponseDay 1 (Baseline) and 30 days post-vaccination

Activity for the serotypes contained in V116 was determined using a PnECL assay. The percentage of participants with a ≥4-fold rise from baseline to at 30 days post-vaccination for IgG responses with 95% confidence intervals are presented.
