A Phase 3, Randomized, Double-blind, Active Comparator-controlled Clinical Study to Evaluate the Safety, Tolerability, and Immunogenicity of V116 in Pneumococcal Vaccine-naïve Adults 50 Years of Age or Older

In Brief

A Phase 3 clinical trial evaluating V116 and PPSV23 for Pneumococcal Disease. Completed, enrolled 1,484 participants across 55 sites in 11 countries.

Detailed Summary

This is a phase 3, randomized, double-blind, active comparator-controlled study of the safety, tolerability, and immunogenicity of V116 in pneumococcal vaccine-naïve adults 50 years of age and older. The polyvalent (23-valent) pneumococcal vaccine, PPSV23, is the active comparator. In addition to studying safety/tolerability, it is hypothesized that, at 30 days postvaccination, the immunogenicity of V116 is noninferior to PPSV23 for the 12 common serotypes in V116 and PPSV23, and that V116 is superior to PPSV23 for the 9 serotypes unique to V116. It is also hypothesized that V116 is superior to PPSV23 in the percentage of participants with ≥4-fold rise from baseline in unique V116 serotypes, as measured by serotype-specific opsonophagocytic activity (OPA) geometric mean titers (GMTs).
