A Single Ascending Dose Study in Adults (Stage 1) and Single Ascending Dose-Finding Study (Stage 2) in Elderly Subjects With ASP3772, A Pneumococcal Vaccine

A Phase 1/2, Randomized, Single Ascending Dose Study in Adults (Stage 1) and Randomized, Single Ascending Dose-Finding Study (Stage 2) in Elderly Subjects With ASP3772, a Pneumococcal Vaccine

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.

What is the study measuring?

Primary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Number of Participants With Treatment Emergent Adverse Events (TEAEs), [Stage 1, Group 1]	An AE is any untoward medical occurrence in a participant administered a study vaccine, and which does not necessarily have to have a causal relationship with this vaccination. A TEAE is defined as any AE with onset within 30 days from study vaccine administration. Medically attended TEAEs (MAAEs) are AEs for which the participant has received medical attention by medical personnel, or in an emergency room, or which led to hospitalization. A new-onset chronic disease TEAEs (NOCD) is defined as a MAAE which a) was absent at baseline; b) has not resolved at the follow-up telephone call; c) requires continuous medical care or attention. Potentially Immune Mediated medical condition TEAEs (PIMMCs) are defined as any AEs of autoimmune or auto inflammatory nature.	From Day 1, Up to Day 180
Number of Participants With TEAEs, [Stage 2, Group 2]	An AE is any untoward medical occurrence in a participant administered a study vaccine, and which does not necessarily have to have a causal relationship with this vaccination.

Medically attended TEAEs (MAAEs) are AEs for which the participant has received medical attention by medical personnel, or in an emergency room, or which led to hospitalization. A new-onset chronic disease TEAEs (NOCD) is defined as a MAAE which a) was absent at baseline; b) has not resolved at the follow-up telephone call; c) requires continuous medical care or attention. Potentially Immune Mediated medical condition TEAEs (PIMMCs) are defined as any AEs of autoimmune or auto inflammatory nature.
