A Phase 3 Randomized, Double-blind, Placebo-Controlled Clinical Study to Evaluate the Safety, Tolerability, and Immunogenicity of V116 When Administered Concomitantly With Influenza Vaccine in Adults 50 Years of Age or Older

In Brief

A Phase 3 clinical trial evaluating V116, QIV, and 1 other intervention for Pneumonia, Pneumococcal. Completed, enrolled 1,080 participants across 56 sites.

Detailed Summary

This a study of V116 in adults ≥50 years of age who concomitantly received Influenza vaccine. The primary objectives of this study are to evaluate the safety, tolerability, and immunogenicity of V116 when administered concomitantly with Quadrivalent Influenza Vaccine (QIV) compared with V116 administered sequentially with QIV. The primary hypotheses state that immune responses to V116 and to QIV are non-inferior when administered concomitantly as compared with sequential administration as measured by serotype-specific opsonophagocytic activity (OPA) for V116 and hemagglutination inhibition (HAI) geometric mean titers (GMTs) for QIV, at 30 days postvaccination.
