A Study to Evaluate the Safety, Tolerability, and Immunogenicity of V114 When Administered Concomitantly With Influenza Vaccine in Healthy Adults 50 Years of Age or Older (V114-021/PNEU-FLU)

Phase 3
Completed
Conditions
Pneumococcal Infections
Interventions
Biological: V114
Biological: QIV
Biological: Matching Placebo for V114
Registration Number
NCT03615482
Lead Sponsor
Merck Sharp & Dohme LLC
Brief Summary

This study was designed to evaluate the safety and tolerability of a single dose of V114 when administered concomitantly and non-concomitantly (i.e., 30 days after) with influenza vaccine. It also evaluated whether V114 can be administered concomitantly with influenza vaccine without impairing the antibody response to the 15 serotypes contained in V114 and to the 4 influenza viruses contained in the seasonal inactivated quadrivalent influenza vaccine (QIV). The primary hypotheses state that immune responses to V114 and to QIV are non-inferior when administered concomitantly as compared with non-concomitant administration as measured by serotype-specific opsonophagocytic activity (OPA) and hemagglutination inhibition (HAI) geometric mean titers (GMTs) at 30 days postvaccination. This study will also contribute to the overall safety database and immunogenicity data for V114 to support initial licensure in adults.

Primary Outcome Measures
NameTimeMethod
Percentage of Participants With a Vaccine-Related Serious Adverse EventUp to 7 months

A serious adverse event (SAE) is an AE that results in death, requires or prolongs an existing hospitalization, results in persistent or significant disability or incapacity, is a congenital anomaly or birth defect, or is another important medical event deemed such by medical or scientific judgment. Relatedness of an SAE to the study vaccine was determined by the investigator.

Geometric Mean Titer (GMT) Ratio of Pneumococcal Serotype-specific Opsonophagocytic Activity (OPA)30 days after V114 vaccination (Day 30 for concomitant vaccination group and Day 60 for non-concomitant vaccination group)

Serotype-specific OPA GMTs (estimated) and GMT ratios with 95% confidence intervals (CIs) and 1-sided p-values were calculated using a constrained longitudinal data analysis (cLDA) method utilizing data from both vaccination groups. Per the statistical analysis plan, the only CIs calculated were the between-group CIs (for the GMT ratios); within-group CIs were not calculated.

Percentage of Participants With a Solicited Systemic Adverse EventUp to Day 14 after any vaccination

An adverse event (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. An AE can therefore be any unfavorable and unintended sign (including an abnormal laboratory finding), symptom, or disease (new or exacerbated) temporally associated with the use of a study intervention. Solicited systemic AEs included myalgia/muscle pain, arthralgia/joint pain, headache, and fatigue/tiredness.

GMT of Influenza Strain-Specific Hemagglutination InhibitionDay 30

Activity for the 4 strains contained in QIV vaccine was determined using an hemagglutination inhibition (HAI) assay. Serotype-specific HAI GMTs (estimated) and GMT ratios with 95% confidence intervals (CIs) and 1-sided p-values were calculated using a constrained longitudinal data analysis (cLDA) method utilizing data from both vaccination groups. Per the statistical analysis plan, the only CIs calculated were the between-group CIs (for the GMT ratios); within-group CIs were not calculated.

Percentage of Participants With a Solicited Injection-site Adverse EventUp to Day 5 after vaccination

An adverse event (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. An AE can therefore be any unfavorable and unintended sign (including an abnormal laboratory finding), symptom, or disease (new or exacerbated) temporally associated with the use of a study intervention. Solicited injection-site AEs included injection-site erythema /redness, pain /tenderness, swelling.

Immunoglobulin G for the 15 serotypes contained in V114 vaccine will be determined using an electrochemiluminescence assay. GMFR is the geometric mean of fold rise from baseline to postvaccination.

Percentage of Participants With GMFR ≥4 in Pneumococcal Serotype-specific OPABaseline and 30 days after V114 vaccination (Day 1 and Day 30 for concomitant vaccination group, and Day 30 and Day 60 for non-concomitant vaccination group, respectively)

Activity for the 15 serotypes contained in V114 vaccine will be determined using a Multiplex Opsonophagocytic Assay. GMFR is the geometric mean of fold rise from baseline to postvaccination. The percentage of participants who had ≥ 4-fold rise in GMFR were calculated from baseline to postvaccination.

Percentage of Participants Who Seroconvert for Influenza Strain-specific HAIBaseline (Day 1) and Day 30

Activity for the 4 strains contained in QIV vaccine will be determined using an HAI assay. Seroconversion for HAI responses is defined as achieving either 1) a 4-fold rise in influenza strain-specific HAI titer from Baseline to Day 30 among participants who are seropositive at Baseline (HAI titer ≥1:10) or 2) a influenza strain-specific HAI titer of ≥1:40 at Day 30 among participants who are seronegative at Baseline (HAI titer \<1:10).

Percentage of Participants With Influenza Strain-specific HAI Titer ≥1:40Day 30

Activity for the 4 strains contained in QIV vaccine will be determined using an HAI assay. Seroconversion is defined as achieving a 4-fold rise from baseline to postvaccination among participants who are seropositive at baseline (HAI titer ≥ 1:10) or a titer of ≥ 1:40 at postvaccination among participants who are seronegative at baseline (HAI titer \< 1:10).

Geometric Mean Concentration (GMC) of Pneumococcal Serotype-specific Immunoglobulin G (IgG)30 days after V114 vaccination (Day 30 for concomitant vaccination group and Day 60 for non-concomitant vaccination group)

Serotype-specific IgG GMC ratios (estimated) and GMC ratios with 95% confidence intervals (CIs) were calculated using a constrained longitudinal data analysis (cLDA) method utilizing data from both vaccination groups. Per the statistical analysis plan, the only CIs calculated were the between-group CIs (for the GMC ratios); within-group CIs were not calculated.

Geometric Mean Fold Rise (GMFR) in Pneumococcal Serotype-Specific OPABaseline and 30 days after V114 vaccination (Day 1 and Day 30 for concomitant vaccination group, and Day 30 and Day 60 for non-concomitant vaccination group, respectively)

Activity for the 15 serotypes contained in V114 vaccine will be determined using a Multiplex Opsonophagocytic Assay. GMFR is the geometric mean of fold rise from baseline to postvaccination.

Activity for the 4 strains contained in QIV vaccine will be determined using an HAI assay. GMFR is the geometric mean of fold rise from baseline to postvaccination.

Percentage of Participants With GMFR ≥4 in Pneumococcal Serotype-specific IgGBaseline and 30 days after V114 vaccination (Day 1 and Day 30 for concomitant vaccination group, and Day 30 and Day 60 for non-concomitant vaccination group, respectively)

Immunoglobulin G for the 15 serotypes contained in V114 vaccine will be determined using an electrochemiluminescence assay. GMFR is the geometric mean of fold rise from baseline to postvaccination. The percentage of participants who had ≥ 4-fold rise in GMFR are calculated from baseline to postvaccination.
