研究概览
简要总结
This study is designed 1) to evaluate the safety, tolerability, and immunogenicity of V114 and Prevnar 13™, 2) to describe the safety of sequential administration of V114 or Prevnar 13™ followed by PNEUMOVAX™23, and 3) to evaluate the immune responses to the 15 serotypes contained in V114 when PNEUMOVAX™23 is given approximately 12 months after receipt of either V114 or Prevnar 13™ in healthy adults 50 years of age or older. There was no formal hypothesis testing.

结局指标
主要结局
Geometric Mean Titer of Serotype-specific Opsonophagocytic Activity at 30 Days Following PNEUMOVAX™23
时间窗: Month 13 (30 days after Vaccination 2)
Serotype-specific opsonophagocytic activity (OPA) geometric mean titers (GMTs) (estimated) and GMT ratios with 95% confidence intervals (CIs) 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) will be determined using a Multiplexed Opsonophagocytic Assay.
Percentage of Participants With Solicited Injection-site Adverse Events Following PNEUMOVAX™23
时间窗: Up to 5 days after Vaccination 2
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 PNEUMOVAX™23, 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.
Percentage of Participants With Vaccine-related Serious Adverse Events Following V114 or Prevnar 13™
时间窗: Up to 12 months after Vaccination 1
A serious adverse event (SAE) is an AE that is life-threatening, 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 will be determined by the investigator. Following vaccination with V114 or Prevnar 13™, the percentage of participants with vaccine-related serious adverse events was assessed.
Percentage of Participants With Vaccine-related Serious Adverse Events Following PNEUMOVAX™23
时间窗: Month 12 to Month 13 (Up to 44 days after Vaccination 2)
A serious adverse event (SAE) is an AE that is life-threatening, 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 will be determined by the investigator. Following vaccination with PNEUMOVAX™23, the percentage of participants with vaccine-related serious adverse events was assessed.
Percentage of Participants With Solicited Injection-site Adverse Events Following V114 or Prevnar 13™
时间窗: Up to 5 days after Vaccination 1
An adverse event (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 injection-site AEs was assessed. The solicited injection-site AEs assessed were redness/erythema, swelling, and tenderness/pain.
Percentage of Participants With Solicited Systemic Adverse Events Following V114 or Prevnar 13™
时间窗: Up to 14 days after Vaccination 1
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.
