Trial overview

Official title: ASP3772 Phase 1 Study: Single Ascending Dose Study in Japanese Healthy Male and Female Adults, and PPSV23-controlled, Randomized, Single Ascending Dose Study in Japanese Elderly Male and Female Subjects
Trial description: The purpose of this study is to evaluate the safety and tolerability of 3 different dose levels of ASP3772 administered subcutaneously or intramuscularly to Japanese healthy adults 20 to 49 years of age.
This study will also evaluate the safety and tolerability of 3 different dose levels of ASP3772 administered subcutaneously or intramuscularly, in comparison to the active comparator 23-valent pneumococcal polysaccharide vaccine (PPSV23) in Japanese elderly subjects 65 to 85 years of age.
