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

Merck Sharp & Dohme LLC·interventional·Posted Jun 21, 2022·Updated Oct 26, 2024

In Brief

A Phase 3 clinical trial evaluating V116 and PCV20 for Pneumococcal Infection. Completed, enrolled 2,663 participants across 112 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 compared to PCV20 (pneumococcal 20-valent conjugate vaccine (\[Prevnar 20™ / APEXXNAR™\]) in pneumococcal vaccine-naïve adults. It is hypothesized that V116 is noninferior to PCV20 for the common serotypes and superior to PCV20 for the unique serotypes as assessed by serotype specific opsonophagocytic activity (OPA) 30 days postvaccination. It is also hypothesized that V116 in participants 18 to 49 years of age immunobridges to V116 in participants 50 to 64 years of age as assessed by serotype specific OPA geometric mean titers (GMTs) 30 days postvaccination for all 21 serotypes in V116. Participants ≥50 years of age will be enrolled in Cohort 1, and participants 18 to 49 years of age will be enrolled in Cohort 2.
