Safety and Immunogenicity of Catch-up Vaccination Regimens of V114 (V114-024)

A Phase 3, Multicenter, Randomized, Double-blind, Active Comparator-controlled Study to Evaluate the Safety, Tolerability, and Immunogenicity of Catch-up Vaccination Regimens of V114 in Healthy Infants, Children, and Adolescents (PNEU-PLAN)

The purpose of this study is 1) to evaluate the safety and tolerability of V114 with respect to the proportion of participants with adverse events (AEs) and 2) to evaluate the anti-pneumococcal polysaccharide (PnPs) serotype-specific Immunoglobulin G (IgG) Geometric Mean Concentrations (GMCs) at 30 days following the last dose for each vaccination group. There is no formal hypothesis testing in this study.

Participants ≥2 years of age could have received a PCV at least 8 weeks prior to study entry as follows: a partial regimen of Prevnar™,Synflorix™, or Prevnar 13™ or a full regimen of Prevnar™ or Synflorix™ based on local guidelines. Participants should not have received any dose of a pneumococcal polysaccharide vaccine

• Has received other licensed non-live vaccines within 14 days before receipt of study vaccine. Exception: Inactivated influenza vaccine may be administered but must be given at least 7 days before receipt of study vaccine or at least 15 days after receipt of study vaccine
• Has received a licensed live vaccine within 30 days before receipt of study vaccine
• Has received a blood transfusion or blood products, including immunoglobulins, within 6 months before receipt of study vaccine
• Has participated in another clinical study of an investigational product before the beginning or anytime during the duration of the current clinical study
