In Brief
A Phase 2 clinical trial evaluating V114-A, V114-B, and 1 other intervention for Pneumococcal Infections. Completed, enrolled 690 participants.
Detailed Summary
The purpose of this study is to assess the safety, tolerability, and immunogenicity of a single dose of different formulations of V114 (V114-A and V114-B) and Prevnar 13® (pneumococcal 13-valent conjugate vaccine) in adult participants ≥50 years of age in good health.

Interventions
Formulation A of V114 contains 2 µg of pneumococcal capsular polysaccharide serotypes 1, 3, 4, 5, 6A, 7F, 9V, 14, 18C, 19F, 19A, 22F, 23F, and 33F; 4 µg of serotype 6B; 32 µg of CRM197 protein carrier; and 125 µg of Aluminum Phosphate Adjuvant in each 0.5 mL dose (V114-A uses a unique excipient to improve stability of the vaccine against physical stress).
Formulation B of V114 contains 2 µg of pneumococcal capsular polysaccharide serotypes 1, 3, 4, 5, 6A, 7F, 9V, 14, 18C, 19F, 19A, 22F, 23F, and 33F; 4 µg of serotype 6B; 32 µg of CRM197 protein carrier; and 125 µg of Aluminum Phosphate Adjuvant in each 0.5 mL dose (V114-B uses a unique excipient to improve stability of the vaccine against physical stress).
Pneumococcal capsular polysaccharide serotypes 1, 3, 4, 5, 6A, 7F, 9V, 14, 18C, 19A, 19F, 23F (2.2 mcg each), and 6B (4.4 mcg) in each 0.5 mL dose.
