Official title

A Phase 3, Multicenter, Randomized, Double-blind, Active Comparator-controlled, Lot-to-Lot Consistency Study to Evaluate the Safety, Tolerability, and Immunogenicity of V114 in Healthy Adults 50 Years of Age or Older (PNEU-TRUE)

Brief summary

Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.

The primary objectives are to evaluate the safety and tolerability of V114 and to compare the serotype-specific opsonophagocytic activity (OPA) geometric mean titers (GMTs) across 3 different lots of V114. The primary hypothesis is that all 3 lots of V114 are equivalent as measured by the serotype-specific OPA GMTs for 15 serotypes in V114 at 30 days postvaccination.
