A Multicenter, Double-Blind Study of the Safety, Tolerability, and Immunogenicity of a Pneumococcal Conjugate Vaccine (V114) Compared to Pneumococcal Polysaccharide Vaccine (PNEUMOVAX® 23) and PREVNAR 13® (Pneumococcal 13-Valent Conjugate Vaccine [Diphtheria CRM197 Protein]) in Healthy Adults 50 Years of Age or Older

In Brief

A Phase 2 clinical trial evaluating Pneumococcal Conjugate Vaccine (V114), PNEUMOVAX® 23, and 1 other intervention for Pneumococcal Infections. Completed, enrolled 692 participants.

Detailed Summary

The purpose of the study is to see if an investigational vaccine for Streptococcus pneumonia disease (V114) has comparable safety, tolerability, and antibody response to Pneumococcal Polysaccharide Vaccine (PNEUMOVAX® 23) and 13-valent Pneumococcal Conjugate Vaccine (PREVNAR 13®) when administered to healthy adults 50 years of age or older. The primary hypothesis is the serotype-specific immunoglobulin G (IgG) geometric mean concentrations (GMCs) as measured by the pneumococcal electrochemiluminescence (Pn ECL) assay at one month postvaccination in subjects who receive V114 will be noninferior to those measured in subjects who receive PNEUMOVAX® 23.
