Brief Summary

The purpose of this study is to evaluate the safety, tolerability and pharmacokinetics and pharmacodynamics of oral doses of FB418 in healthy adult subjects and healthy elderly subjects.

Detailed Description

Part A:

Primary:

To assess the safety and tolerability of single ascending oral doses of FB418 in healthy adult subjects and healthy elderly subjects.

Secondary:

To assess the pharmacokinetics (PK) of FB418 and metabolite after single ascending oral doses of FB418 in healthy adult subjects and healthy elderly subjects.

To assess the effect of a high-fat meal on the PK of FB418 and metabolite after a single oral dose of FB418 when administered to healthy adult subjects.

Part B:

Primary:

To assess the safety and tolerability of multiple ascending oral doses FB418 in healthy adult subjects.

Secondary:

To assess the PK of FB418 and metabolite after multiple ascending oral doses of FB418 in healthy adult subjects.
