Study Overview
Brief Summary
The purpose of this study is to 1) evaluate the safety and tolerability of V114 and 2) to compare the immune responses of the 15 serotypes contained in V114 with V114 versus Prevnar 13™. The primary hypotheses are that 1) V114 is noninferior to Prevnar 13™ as measured by the serotype specific opsonophagocytic activity (OPA) geometric mean titers (GMTs) for 13 shared serotypes at 30 days postvaccination and that 2) V114 is superior to Prevnar 13™ as measured by serotype-specific OPA GMTs for 2 unique serotypes in V114 at 30 days postvaccination.

- •Has received any non-live vaccine within the 14 days before receipt of any study vaccine or is scheduled to receive any non-live vaccine within 30 days following receipt of any study vaccine. (Exception: Inactivated influenza vaccine may be administered but must be given at least 7 days before receipt of any study vaccine or at least 15 days after receipt of any study vaccine.)
- •Has received any live vaccine within 30 days before receipt of any study vaccine or is scheduled to receive any live vaccine within 30 days following receipt of any study vaccine.
- •Has received a blood transfusion or blood products, including immunoglobulin, within the 6 months before receipt of study vaccine or is scheduled to receive a blood transfusion or blood product within 30 days of receipt of study vaccine. Autologous blood transfusions are not considered an exclusion criterion.
- •Currently participating in or has participated in an interventional clinical study with an investigational compound or device within 2 months of participating in this current study.
- •In the opinion of the investigator, has a history of clinically relevant drug or alcohol use that would interfere with participation in protocol-specified activities.
- •History or current evidence of any condition, therapy, laboratory abnormality, or other circumstance that might expose the participant to risk by participating in the study, confound the results of the study, or interfere with the participant's participation for the full duration of the study.
- •An immediate family member (e.g., spouse, parent/legal guardian, sibling, or child) who is investigational site or Sponsor staff directly involved with this study.
Arms & Interventions
Prevnar 13™
Single IM dose at 0.5 mL of Prevnar 13™ at Visit 1 (Day 1)
Intervention: Prevnar 13® (Biological)
V114
Single intramuscular (IM) dose at 0.5 mL of V114 pneumococcal conjugate vaccine at Visit 1 (Day 1)
Intervention: V114 (Biological)
Outcomes
Primary Outcomes
Percentage of Participants With Solicited Systemic Adverse Events
Time Frame: Up to Day 14 postvaccination
An AE is any untoward medical occurrence in a patient or clinical study participant, temporally associated with the use of study treatment, whether or not considered related to the study treatment. Following vaccination with V114 or Prevnar 13™, the percentage of participants with solicited systemic AEs was assessed. The solicited systemic AEs assessed were muscle pain/myalgia, joint pain/arthralgia, headache, and tiredness/fatigue.
Geometric Mean Titer of Serotype-specific Opsonophagocytic Activity at Day 30
Time Frame: Day 30
Serotype-specific opsonophagocytic activity (OPA) geometric mean titers (GMTs) (estimated) and GMT ratios with 95% CIs and 1-sided p-values were calculated using a constrained longitudinal data analysis (cLDA) model 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. OPA for the serotypes contained in Prevnar 13™ and V114 (13 serotypes shared with Prevnar 13™ and 2 serotypes unique to V114) were determined using a multiplexed opsonophagocytic assay (MOPA). The measure type of "number" presented in the data table below for serotype-specific OPA titer is the geometric mean.
Percentage of Participants With a Solicited Injection-site Adverse Event
Time Frame: Up to Day 5 postvaccination
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. Solicited injection-site AEs consist of redness/erythema, swelling, and tenderness/pain.
Percentage of Participants With a Vaccine-related Serious Adverse Event
Time Frame: Up to Month 6
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. SAEs that are reported to be at least possibly related by the investigator to study vaccination will be summarized.
Percentage of Participants With ≥4 Fold Rise in Serotype-specific OPA for 2 Unique V114 Serotypes
Time Frame: Day 1 (Baseline) and Day 30
Activity for the serotypes contained in Prevnar 13™ and V114 was determined using a multiplexed opsonophagocytic assay (MOPA). The percentage of participants who had ≥4-fold rise in OPA titers were calculated from baseline (Day 1) to 30 days postvaccination (Day 30) for OPA responses for the 2 unique serotypes in V114. The observed response percentage (m/n) included: m=the number of participants with the indicated response divided by n=the number of participants contributing to the analysis. Per the statistical analysis plan, the only CIs calculated were the between-group CIs (for the percentage point difference); within-group CIs were not calculated.
