Brief Summary: The purpose of the study is to evaluate the safety, tolerability, and immunogenicity of 3 different dose levels of ASP3772 in comparison to the active comparator Prevnar 13® (PCV13) in adults 18 to 64 years of age in Stage 1. Stage 2 will evaluate the safety, tolerability, and immunogenicity of 3 different dose levels of ASP3772 in comparison to the active comparator PCV13 in elderly 65 to 85 years of age. In addition, Stage 2 will evaluate the immunogenicity of 3 different dose levels of ASP3772 relative to the response seen following administration of Pneumovax® 23 (PPSV23) for the serotypes not included in PCV13.
Detailed Description: The study population will consist of 3 different groups: Group 1 - Stage 1 PCV13 naïve participants randomized within 3 sequential cohorts to ASP3772 or PCV13; Group 2 - Stage 2 PCV13 naïve participants randomized within 3 sequential cohorts to ASP3772 or PCV13; and Group 3 - Stage 2 participants previously vaccinated with PCV13 that will receive PPSV23.
