Sequential Administration of Prevnar 13™ and Pneumovax™ 23 in Healthy Subjects 50 Years of Age and Older

Merck Sharp & Dohme LLC·interventional·Posted Aug 26, 2014·Updated Nov 2, 2021

In Brief

A Phase 3 clinical trial evaluating Prevnar 13™, Pneumovax™ 23, and 1 other intervention for Pneumococcal Infections. Completed, enrolled 400 participants.

Detailed Summary

The purpose of this study is to evaluate the safety and immunogenicity of sequential administration of Prevnar 13™ and Pneumovax™ 23 in healthy participants 50 years of age and older. The primary hypotheses in the study are that 1) geometric mean titers (GMTs) to pneumococcal serotypes 22F and 33F (serotypes in Pneumovax™ 23 but not in Prevnar 13™) as measured at Week 12 are superior in participants administered Prevnar 13™ on Day 1 and Pneumovax™ 23 at Week 8, as compared with participants administered Prevnar 13™ on Day 1 and placebo at Week 8 and 2) GMTs to pneumococcal serotypes shared by the two vaccines as measured at Week 12 are non-inferior in participants administered Prevnar 13™ followed by Pneumovax™ 23 as compared with participants administered Prevnar 13™ followed by placebo.
